PUBLIC LAND MANAGEMENT IN HOA LOI WARD, HO CHI MINH CITY: ASSESSMENT OF THE CURRENT SITUATION IN 2025 AND PROPOSED SOLUTIONS UNTIL 2030.
type: item
description: In the context of increasing land use demand and the need to improve the efficiency of land resource management in urban areas, the management of public land in Hoa Loi Ward, Ho Chi Minh City, is raising many issues that need to be evaluated and improved. Using methods of document collection and analysis, field surveys, expert and community consultations, combined with processing secondary data from state management agencies and the list of public land areas, this study aims to assess the current state of public land, the management situation, and propose solutions to improve the efficiency of public land management and use in the study area. The results show that the total area of public land is 24.97 hectares, classified into 6 types, with cemetery land accounting for the largest proportion at 11.34 hectares (45.41%). Comparison with the land use plan until 2030 shows that 6 plots of land for public works will continue to be used stably, and 14 plots of cemetery land are slated for relocation. Based on this, the study proposes 4 groups of solutions to strengthen the management of public land, among which the solution of publicly disclosing information, marking boundaries, and installing signs indicating the location of public land is considered the most important, with a 74% agreement rate. The study shows that transparency of information and enhanced on-site identification of public land areas are key factors in improving management efficiency, contributing to the rational and sustainable use of public land resources in the locality.

A STUDY ON CASH MANAGEMENT IN SMALL AND MEDIUM-SIZED ENTERPRISES AND SOME MANAGEMENT IMPLICATIONS
type: item
description: The research aims to assess the factors affecting cash holdings in small and medium-sized enterprises (SMEs) in Vietnam from 2012 to 2024. Quantitative analysis using FGLS regression analysis ensures no autocorrelation or heteroskedasticity. The robustness testing and cross-sectional dependency assessment are performed using PCSE and Driscoll-Kraay regression. The research results suggest that there exists a negative impact between financial leverage and cash holdings, particularly in enterprises with its low level of cash holdings. Smaller enterprises tend to maintain higher cash holdings. Expanding the size of the board of directors can lead to higher cash holdings. Finally, the study discusses several management implications for improving business performance.

STUDY ON THE IN VITRO PROPAGATION OF Anoectochilus sp.
type: item
description: Anoectochilus sp. is a medicinal plant with many valuable healing properties. It has long been used in traditional medicine as a remedy for ailments such as stomach pain and high fever. However, due to overexploitation, this species is now endangered in the wild. This article investigates the influence of auxin compounds and substrates on the growth of Anoectochilus sp. to develop an in vitro rapid propagation. The results showed that the Gamborg B5 medium supplemented with 4 mg/L indole-3-butyric acid (IBA) yielded the best results, with the average number of shoots, leaves, and roots per original sample reaching 2.56 shoots/sample, 5.00 leaves/shoot, and 4.33 roots/shoot, respectively. The mixed substrate in the treatment, consisting of pine bark (40%), coconut fiber (10%), burnt rice husk (10%), soil (10%), and cow manure (20%), was suitable for the growth of Anoectochilus sp. seedlings. Seedlings grown on this substrate reached a height of 7.72 cm with 5.00 leaves/plant and 3.20 roots/plant, respectively, and a survival rate of 100% after 12 weeks of planting. This research has provided a valuable scientific and practical basis, laying the foundation for breeding, conservation, and the future development of this orchid species

FORMULATION FOR A FACE WASH GEL CONTAINING MEDICINAL HERB (Houttuynia cordata Thunb.) AND TEA TREE ESSENTIAL OIL (Melaleuca alternifolia C.)
type: item
description: In the context where health and natural beauty are increasingly emphasized, skincare cleansing products that support acne treatment through antibacterial properties are gaining research attention. Houttuynia cordata Thunb., a common medicinal plant in Vietnam, possesses anti-inflammatory and antibacterial effects. When combined with tea tree oil—an essential oil proven to have antibacterial and anti-inflammatory properties—it can be effectively applied in skincare products. This study developed a facial cleansing gel formulation containing Houttuynia cordata extract and tea tree oil with the following composition: concentrated Houttuynia extract (4%), tea tree oil (0.2%), hydroxypropyl methyl cellulose (0.6%), hydroxyethyl cellulose (0.4%), cocamidopropyl betaine (4.5%), sodium lauryl sulfate (0.5%), glycerin (5%), propylene glycol (5%), triethanolamine (0.2%), citric acid (0.2%), sodium benzoate (0.2%), and purified water up to 100%. The obtained product is light brown in color, with a clear, viscous, and homogeneous gel consistency, producing fine foam with a characteristic fragrance, showing no phase separation. It exhibits antibacterial activity against Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Klebsiella pneumoniae). The evaluation results indicate that the product meets cosmetic quality standards, with a pH ranging from 4.5 to 6.5, appropriate viscosity (648–950 mPa·s), and is safe and pleasant for users.

EFFECT OF SOME FACTORS TO PROTEIN SOLUTION YIELD FROM THE Cordyceps militaris SPENT USING PAPAIN
type: item
description: The Cordyceps militaris spent after receiving fruit body processing is a source of high nutrient by-product that has not been effectively reused. In this study, the effect of some factors on the protein solution yield was determined and optimized. From that, the papain activity and hydrolytic time were determined to enhance the protein solution yield. At the mushroom spent ratio of 7.5%, the optimized result by response surface methodology showed the highest protein content of 20.3 ± 1.2 mg/mL at 54 oC for 20 hours. Adding papain activity of 0.3 U/g mushroom spent for 3 hours helps enhance the protein content in the extract solution, reaching 24.4 ± 0.6 mg/mL. The result showed the potential extraction protein from C. militaris spent to produce rich nutrient food drinks

ANALYSIS OF SOME APPLICATIONS OF THE EXPONENTIAL FUNCTION IN OLYMPIAD-TYPE PROBLEMS FOR UNIVERSITY STUDENTS
type: item
description: The exponential function plays a very important role in mathematics due to its special properties related to its derivative and antiderivative. The exploitation of the properties of the exponential function has been carried out in many different areas, such as problem solving and finding solutions of differential equations. In this paper, we study several applications of the exponential function in solving types of problems that often appear in Mathematical Olympiad examinations for university students. In particular, we analyze several bases or indications showing that the exponential function can be used to handle such problems. These analyses may be useful for students who are interested in studying and practicing Olympiad-type problems for university students.

CONSTRUCTION OF EXPLICIT SOLUTION FORMULAS FOR VOLTERRA INTEGRAL EQUATIONS VIA THE METHOD OF SUCCESSIVE APPROXIMATIONS
type: item
description: Integral equations have numerous applications in science and engineering, as they model phenomena with memory effects or global interactions. Various methods have been developed for solving integral equations, including the method of successive approximations, series methods, fixed point theorems, integral transform techniques, and numerical approaches. In this paper, we investigate several classes of integral equations that commonly arise in the study of differential equations involving derivatives of non-integer order. By applying the method of successive approximations, we construct explicit solution formulas for these integral equations. The proposed method can be extended to other classes of integral equations. Moreover, the obtained solutions provide a basis for studying qualitative properties of solutions to nonlinear fractional integro-differential equations.

DIGITALIZATION OF BENEFICIAL OWNERSHIP INFORMATION IN STATE-OWNED ENTERPRISES: CHINA’S EXPERIENCE AND LESSONS FOR VIETNAM
type: item
description: The article aims to analyze the legal framework for transparency and digitalization of beneficial ownership (Beneficial Owner - BO) information in accordance with the standards of the Financial Action Task Force (FATF), while comparing the approaches of Vietnam and China in the context of digital transformation. The study employs legal analysis, comparative law, and synthesis of academic literature. The research findings show that Vietnam has initially established a legal framework for BO and implemented digitalization of information through the enterprise registration system; however, the identification of substantive control and the utilization of BO data remain fragmented and not yet linked to risk management. Meanwhile, China has developed a data-driven governance model, integrating BO information into the national financial supervisory system. Based on the approach to BO grounded in substantive control, the article uses the criterion of “the ability to trace substantive control” as a measure to assess the effectiveness of information digitalization mechanisms. On that basis, the article proposes several directions for improving Vietnam’s legal framework, focusing on codifying the principle of substantive control, enhancing data interoperability, and using BO information as a governance tool for state-owned enterprises in the digital environment.

FOURTH-GRADE STUDENTS’ AWARENESS AND EATING BEHAVIORS: A STUDY AT A MY HIEP PRIMARY SCHOOL, AN GIANG
type: item
description: This study examines the awareness and eating behaviors of fourth-grade students at A My Hiep Primary School, An Giang Province, and proposes nutrition education orientations appropriate to the current primary education context. A quantitative cross-sectional survey was conducted with 54 students using a questionnaire covering three main dimensions: awareness of healthy eating, daily eating behaviors, and the need for additional nutrition knowledge. The findings indicate that students had developed relatively positive initial awareness of several basic issues, including dietary diversity, the role of water, and balanced meals. However, their understanding was uneven across topics; more abstract and systematic knowledge such as nutrient groups and the food pyramid received lower mean scores. In terms of behavior, most students reported having breakfast and drinking water relatively regularly, while balanced intake across food groups and control of fast-food consumption remained limited. The results also suggest a certain relationship between awareness, learning interest, and classroom participation in nutrition-related activities. Based on these findings, the study recommends strengthening nutrition education through visual and experiential approaches, integrating nutrition content into Science lessons, and enhancing coordination among schools, families, and educational and health authorities to foster sustainable healthy eating habits among primary school students.

POST-WAR TRAUMA, MIGRATION, AND FEMALE IDENTITY IN KAZUO ISHIGURO'S A PALE VIEW OF HILLS
type: item
description: In recent decades, trauma literature has increasingly attracted scholarly attention. A Pale View of Hills by Kazuo Ishiguro is a representative work within this literary tradition. Employing a literary analytical approach combined with theories of trauma, migration, and feminism, this study clarifies the structure of trauma in the novel. The findings indicate that trauma does not operate in a linear manner but rather as a layered structure. Postwar trauma forms the initial psychological foundation for Etsuko, motivating her decision to migrate; migration trauma manifests through Keiko’s sense of alienation, loneliness, and fractured identity; gender-based trauma leads Etsuko to internalize guilt, assume responsibility, and endure her tragedy as a form of self-imposed punishment. The study affirms that personal tragedy arises not only from external events such as war but also from crises of adaptation within migratory spaces and the pressures of social norms, particularly those imposed on women. Accordingly, the article contributes to elucidating how trauma is constructed and layered in the literary works of Kazuo Ishiguro

THE ART OF SITUATIONAL CONSTRUCTION IN VIET THANH NGUYEN'S SHORT STORY COLLECTION THE REFUGEES
type: item
description: This article examines the art of constructing narrative situations in Viet Thanh Nguyen’s short story collection The Refugees through the combined perspectives of psychoanalytic criticism, existential philosophy, and migration literature studies. Conceiving narrative situation as the structural core through which a text’s central conflict is organized and revealed, the study focuses on two prominent dimensions: situations of hardship and ordeal associated with the journey of escape by sea and the provisional life in refugee camps, and situations of cultural conflict arising in the context of resettlement. Through an analysis of representative stories, the article shows that Nguyen frequently constructs pivotal circumstances, interweaves the present with memory, and employs strategic silences together with symbolically charged details to foreground psychological trauma, the sense of exile, and the crisis of identity experienced by his characters. In this way, narrative situations function not only as mechanisms for advancing the plot but also as artistic devices for expressing psychological depth and the migrant subject’s ongoing negotiation of identity within multicultural spaces.

THE SETTLEMENT PROCESS OF CATHOLIC MIGRANT COMPATRIOTS IN THỦ DẦU MỘT - BÌNH DƯƠNG PROVINCE FROM 1954 TO 1957
type: item
description: After 1954, Thủ Dầu Một - Bình Dương became one of the key areas in southern Vietnam for receiving and organizing the settlement of northern migrants, the majority of whom were Catholic communities originating from Hải Phòng. This study applies the historical method combined with archival analysis, based on materials collected from the National Archives Center No. II. The article focuses on clarifying the formation and stabilization of settlement villages and camps of this community during the period 1954 - 1957. The findings indicate that the settlement process was carried out under the organization of local authorities, beginning with the establishment of settlement units in late 1954, followed by the gradual stabilization of livelihoods, organizational consolidation, and administrative legalization during 1955 - 1957. Due to specific administrative characteristics, the localization of these settlements occurred in two phases, corresponding to units under the former Thủ Dầu Một Province and the newly established Bình Dương Province. In addition, the migrant Catholic community adopted a mixed-village model to adapt to the new environment while maintaining their religious life and traditional cultural values. This study contributes to supplementing historical sources and clarifying the characteristics of the settlement process of northern Catholic migrants in Southeast Vietnam during this period.

INTERNATIONAL PRESS SPEECH ON THE END OF THE VIETNAM WAR ON APRIL 30, 1975
type: item
description: The end of the Vietnam War on April 30, 1975, was not only a crucial historical turning point for Vietnam but also attracted widespread international media attention. Using discourse analysis combined with qualitative content analysis of articles published in American and Western newspapers such as The New York Times, The Washington Post, The Guardian, Le Monde, and news agencies like Reuters and Associated Press between April 29 and May 5, 1975, this paper aims to analyze how international media constructed discourse about this event. The results show that international media formed four main discourse groups: discourse about "the collapse," discourse about "American failure," humanitarian discourse, and discourse within the context of the Cold War. There are distinct differences among news outlets in their approach to this event: American newspapers tend to approach it from an internal perspective, European newspapers lean towards historical and political analysis, while international news agencies emphasize narrative and relative neutrality. Based on this, the article asserts that journalism not only reflects events but also actively participates in the process of constructing historical meaning through specific discourse frameworks. The research contributes to clarifying the role of media in shaping global perceptions of the Vietnam War, while also opening up an interdisciplinary approach between history and media in the study of modern historical events

UNIVERSITY BRAND IDENTITY THROUGH THE LENS OF CONSTRUCTIVE JOURNALISM: A CASE STUDY OF THU DAU MOT UNIVERSITY
type: item
description: This article analyzes the applicability of constructive journalism in the brand communication of Thu Dau Mot University following its administrative transition to Ho Chi Minh City on July 1, 2025, amid increasingly fierce competition in student recruitment. The study employs a qualitative content analysis of 102 media products published on TDMU’s website, Facebook, and YouTube from July 2025 to March 2026. The evaluation is based on the SEFC framework, comprising four criteria: solution orientation, empowerment, future orientation, and contextualization. Findings indicate that TDMU’s communication activities remain predominantly event-driven, lacking in-depth narratives and solution-oriented values. Comparative analysis with selected domestic and international universities reveals significant limitations, particularly in providing context and articulating a future vision. Consequently, the university's academic strengths have not been effectively transformed into a resonant brand image. Based on these results, the study proposes key strategic directions: developing a constructive storytelling system centered on people and achievements; enhancing contextual depth and comparative data; shifting content production toward a solution-based approach; consistently leveraging distinctive institutional advantages; and expanding communication channels within the Ho Chi Minh City market. This research contributes practical value as one of the pioneering studies in Vietnam to apply the SEFC framework in evaluating university communication within the context of administrative restructuring.

SAIGON COFFEE CULTURE IN THE DIGITAL LIFE: SPATIAL PRACTICES AND EXPERIENCES OF URBAN YOUTH IN HO CHI MINH CITY
type: item
description: This study analyzes the role of coffee shops as a vital socio-cultural institution for youth in Ho Chi Minh City amidst rapid urbanization and pervasive digitalization. Utilizing a qualitative approach (in-depth interviews and field observations), the research frames coffee-going as an everyday spatial practice, where emotional experiences and identity negotiation strategies are constructed between the physical urban environment and the digital realm. Findings indicate that for urban youth, the coffee shop is more than a place for consumption or work; it functions as a space to "dwell," allowing individuals to maintain a minimal social presence. Digital practices such as photographing, posting, or intentionally withholding experiences on social media are interpreted as "digital social rituals." Through these rituals, young people simultaneously assert their digital presence and navigate the boundaries between self-presentation and private life. Furthermore, coffee shops operate as intermediary spaces where a sense of belonging and urban memories are accumulated through repetitive practices. From a digital humanities perspective, the article argues that digital life should be understood not as a detached technological domain, but as a humanistic space shaped by concrete lived experiences. Through the case of Saigon coffee culture, the study elucidates how everyday practices contribute to the construction of a hybrid digital-physical urban life, while expanding the discourse on the role of semi-public spaces in shaping the identity of contemporary urban youth.

ASSESSMENT OF THE IMPACT OF THE EXPANSION PLAN FOR TRANSPORTATION LAND ON THE LIVELIHOODS OF RESIDENTS ALONG DT 741 ROAD, DONG PHU COMMUNE, DONG NAI PROVINCE
type: item
description: The planning and expansion of transportation land is a key driver of regional connectivity, but it also creates profound changes to the livelihoods of local communities. This study focuses on assessing the impact of planning and expanding transportation projects on households through the Sustainable Livelihood Framework (DFID). Survey results show that, thanks to realistic compensation policies, people's short-term financial resources have increased significantly. 41.5% of households have improved their living standards by shifting to trade and services, while 58.5% have maintained stability and promoted the shift in livelihoods towards reducing dependence on agriculture and increasing trade and service activities. This article proposes the application of Geographic Information Systems (GIS) and Inverse Weighted Interpolation (IDW) algorithms to construct land price maps, ensuring transparency and suggesting appropriate adjustment coefficients (1.41 - 1.50) to ensure social welfare and limit conflicts of interest during the implementation of land expansion plans for transportation infrastructure.

RESEARCH AND DEVELOPMENT OF PAPAYA LEAF (Carica papaya L.) TEA BAG PRODUCTS
type: item
description: Papaya leaves (Carica papaya L.) are a rich source of polyphenols with significant bioactive properties and have long been utilized as a traditional herbal remedy to support various health conditions. However, the application of papaya leaves in convenient beverage products remains limited. This study aimed to evaluate the effects of technological parameters such as drying temperature and time, formulation and blending ratio with stevia, as well as infusion water volume and steeping time on the quality of papaya leaf tea bags. Results indicated that the optimal drying condition was 60°C for 6 hours, yielding a final moisture content of 7,03%, total polyphenol content of 19,50 mg GAE/g dry matter, and antioxidant capacity (DPPH assay) of 35,92 µmol TE/g dry matter. The optimal blending ratio of papaya leaves to stevia was determined as 3:1, providing the highest sensory scores. Brewing trials showed that an infusion ratio of 3 g tea bag per 150 mL hot water for 5 minutes resulted in superior sensory quality while maintaining high polyphenol content and antioxidant activity. This study contributes to the development of a standardized processing protocol for papaya leaf tea bags with stable quality and convenience, thereby diversifying herbal tea products

A REVIEW OF RESEARCH ON BIOLOGICAL ACTIVITIES OF QUERCETIN
type: item
description: Quercetin is a naturally occurring flavonoid widely distributed in many plant species and is known for its many important biological activities. This article summarizes and analyzes published studies on the biological activity of quercetin, focusing on its antioxidant, anti-inflammatory, antibacterial, anticancer, and cardioprotective effects. Experimental evidence shows that quercetin can regulate oxidative stress, inhibit inflammatory responses by modulating related cytokines and enzymes, and help protect cells from damage caused by free radicals. In addition, the article outlines common quercetin extraction methods, including solvent extraction, ultrasonic extraction, and green solvent technology, to improve the compound's efficiency and purity. Although quercetin is considered to have potential applications in supporting the treatment of chronic diseases such as diabetes, cardiovascular disease, and cancer, limitations in bioavailability and stability still necessitate further research to optimize practical applications.

DEVELOPMENT OF AN INTEGRATED DATA WAREHOUSE AT THU DAU MOT UNIVERSITY
type: item
description: In the context of university autonomy and digital transformation, data-driven decision-making has become an urgent requirement. However, the most significant challenge facing universities today is data fragmentation and the lack of interoperability between functional departments. This paper presents the process of building and deploying an integrated Data Warehouse (DWH) system at Thu Dau Mot University. The study proposes a modern system architecture based on the Lakehouse model, which combines the flexible storage capabilities of a Data Lake with the structural management of a traditional DWH. The system utilizes Apache Doris technology for high-speed big data processing and Apache Superset for data visualization. Experimental results demonstrate that the system has successfully integrated data from training, admissions, and scientific research modules, providing real-time multi-dimensional analysis dashboards. This system enables university leadership to gain a comprehensive view of operations, thereby enhancing governance efficiency and strategic planning.

CHANGES IN THE PROTOTYPICAL STRUCTURE OF THE IMAGE OF NGUYỄN HUỆ IN VIETNAMESE PROSE AFTER 1986
type: item
description: This article clarifies the transformations in the prototypical structure of the heroic image of Nguyễn Huệ under the impact of innovations in artistic thinking. By examining representational strategies across the dimensions of appearance, action, conduct, and dialogue, the study argues that many works no longer absolutize traditional prototypical markers; instead, they progressively reconstruct the character by incorporating everyday elements, personal emotions, and humanistic values. This process of transformation does not dismantle the existing prototypical foundation but renders its structure more flexible, “open,” and dialogically dynamic. Accordingly, Nguyễn Huệ continues to be affirmed as a symbol of the historical hero while also emerging as a multidimensional artistic figure that reflects shifting conceptions of the human subject in Vietnamese literature after 1986.

THE BELT AND ROAD INITIATIVE: CHINA'S GRAND STRATEGY
type: item
description: The Belt and Road Initiative (BRI) can be approached as a long-term strategic framework of China, implemented in a manner distinct from the Western model of grand strategy, which is usually articulated through clearly formulated doctrines. Rather than being defined by a single unified strategic document, China’s strategic thinking is primarily identified through policy practices and relatively stable patterns of behavior over time. From this perspective, BRI displays three characteristics commonly associated with “grand strategy” in the behavioral sense: (i) its linkage to a long-term political vision of national rejuvenation, in which the year 2049 represents a general national goal rather than a specific deadline for the completion of BRI; (ii) its capacity to mobilize and coordinate national resources across the economic, diplomatic, and geopolitical domains; and (iii) the emergence of a relatively consistent pattern of behavior across the Eurasian space, particularly in the Rimland region. Through the case of BRI, this article argues that China is shaping a new model of international relations in which infrastructure connectivity—rather than military power—becomes a key instrument for structuring power. Accordingly, the study contributes to the theoretical approach that the Belt and Road Initiative should not be understood merely as an economic program, but rather as a strategic instrument through which China seeks to reposition its role in a transforming international order.

THE ART OF HÁT BỘI IN THE SOUTH CENTRAL COASTAL REGION: DEVELOPMENTAL TRAJECTORIES AND VALUE CONSTRUCTION
type: item
description: The art of Hát Bội in Vietnam’s South Central Coastal region is undergoing profound transformations in both performative regimes and value configurations. Conceptualizing artistic practice as a cultural system, and drawing on ethnographic fieldwork—including participant observation and in-deep interviews conducted in selected localities in 2025—this study identifies and analyzes the core values of Hát Bội and examines its role in the production of cultural meaning and audience experience. The findings indicate that Hát Bội mobilizes three interrelated value clusters: (i) values of cultural identity formation; (ii) aesthetic values embedded in the genre’s distinctive performative grammar; and (iii) moral–pedagogical values. The article further demonstrates that these value clusters are being reconfigured through shifting aesthetic norms, the increasing commodification of performance under market conditions, and the institutional reframing of moral values within formal education. It argues that sustainable safeguarding and valorization of Hát Bội must be grounded in a holistic recognition of its culturally embedded value system, rather than an exclusive emphasis on performative technique or formal representation

A COMPREHENSIVE SURVEY ON PERSONALIZED FEDERATED LEARNING
type: item
description: Federated learning (FL) has emerged as a promising paradigm for distributed machine learning that preserves data privacy while enabling collaborative model training. However, standard FL assumes all clients share identical task objectives, which often proves unrealistic in practical applications where clients exhibit heterogeneous data distributions and varying learning goals. Personalized federated learning (PFL) addresses this fundamental limitation by enabling clients to learn personalized models tailored to their specific requirements while leveraging the benefits of distributed collaboration. This survey provides a comprehensive overview of personalized federated learning, covering: (1) fundamental concepts and motivations; (2) classification of PFL approaches; (3) key challenges; and (4) open research directions. We also discuss the trade-offs between personalization and generalization, analyze existing solutions, and identify future challenges in this rapidly evolving field.

ASSESSMENT OF GROUNDWATER QUALITY IN NORTH HO CHI MINH CITY USING GWQI INDEX AND IDW INTERPOLATION
type: item
description: Groundwater plays a crucial role as a resource, providing water for domestic use and supporting socioeconomic development. The northern region of Ho Chi Minh City (HCMC) is under significant pressure from industrialisation, which has required to a growing demand for water, while surface water sources are declining in both quantity and quality. This study applies a Groundwater Quality Index in conjunction with the Inverse Distance Weighting spatial interpolation method to assess, zone, and determine the quality level of groundwater. Research data were collected from the HCMC Department of Agriculture and Rural Development over the period of 2019 - 2023. The results indicate that the majority of monitoring points have a mean water quality index ranging from medium to very good (146.7-41). Groundwater quality remains good to very good across the three main aquifers: the Middle-Upper Pleistocene (qp2-3), Lower Pleistocene (qp1), and Middle Pliocene (n22). These aquifers are generally less affected by anthropogenic pollution sources. From 2021 to 2023, groundwater quality in most areas showed marked improvement, thereby contributing to overall improvement in the study area.

ASSESSING POTENTIAL EXTRACTION OF CHLOROPHYLL FROM SOME PLANTS FOR THE SUPPLEMENT FOODS
type: item
description: The plants that have the dark green leaf are an abundant source of chlorophyll, a group of phytochemicals that possess many health benefits. The study was to assess the composition and content of chlorophyll from some popular leaves such as Sauropus androgynous, Piper sarmentosum, and Sphagneticola calendulacea, when isolated with different concentrations of ethanol. At 80% ethanol, the P. sarmentosum leaves showed the highest yield of chlorophyll for 2.5 – 3 hours (102.65 – 114.08 µg/ml) and the S. calendulacea leaves showed the highest yield of chlorophyll for 2 – 3 hours (50.21 – 52.99 µg/ml). While, the chlorophyll isolation from the S. androgynous leaves got the highest yield with 90% ethanol for 2.5-3 hours (91.51 – 95.63 µg/ml). The chlorophyll content of the P. sarmentosum leaves, S. calendulacea leaves, and S. anhrogynous leaves was 64.2%, 70%, and 72.8%, respectively. The result showed the P. sarmentosum leaf was a potential source of chlorophyll to produce the kinds of supplement foods that are good for health

APPLICATION OF DETERMINANT OF GRAM MATRIX TO CALCULATE DISTANCE IN GEOMETRY
type: item
description: Distances in n-dimensional Euclidean geometry are mainly the distance from a point to a hyperplane and the distance between two skew hyperplanes. Distances in grade 11th spatial geometry are mainly the distance from a point to a line, the distance from a point to a plane and the distance between two skew lines. In Euclidean geometry, the application of the determinant of the Gram matrix will calculate the distance between any two hyperplanes. By using this formula for some 11th grade spatial geometry problems, we have more calculation tools and can quickly find the answer. The article presents distance formulas in Euclidean geometry with illustrative examples. From there, applying the above formulas to solve some problems in 11th grade spatial geometry

DESIGNING EDUCATIONAL GAMES TO ENHANCE PUBERTAL HEALTH AWARENESS AMONG 5TH-GRADE STUDENTS AT A MY HIEP PRIMARY SCHOOL, AN GIANG
type: item
description: Education on adolescent health care plays a crucial role for 5th-grade students during the transitional period to lower secondary school. This study was conducted at A My Hiep Primary School (Cu Lao Gieng Commune, An Giang Province) with the participation of 16 teachers and 49 5th-grade students, aiming to assess the current situation, needs, and effectiveness of integrating educational games into teaching the topic “Adolescent Health Care.” A questionnaire-based survey was administered before and after the implementation of learning games integrated into Science lessons following the 2018 General Education Curriculum. The findings reveal that teachers demonstrated a high level of awareness regarding the role of educational games in fostering students’ knowledge, skills, and attitudes; however, their competence in designing and organizing such games remains limited. Students showed enthusiasm, active participation, and positive improvement in awareness after the learning activities. Based on the results, the study proposes several suitable games to enhance the effectiveness of adolescent health education in primary Science instruction.
