Improving the law on securing obligations by mortgage third party assets
Mortgage of assets is one of the common measures of securing obligations, in which a mortgage relationship arises with the assets of a third party to ensure the performance of clearly existing obligations. However, there are currently many opinions that there is ambiguity between this relationship and the guarantee relationship. It would be normal if civil law clearly recorded mortgages with third-party assets to ensure the performance of obligations in the general legal regulations on mortgages. In contrast, issues of right require the mortgagee to repay the corresponding amount when the third party's assets are liquidated by the mortgagee; similarly for the right to receive remuneration upon completion of work; The relationship between the mortgagee and the mortgagee is unclear, and the rights and obligations of the mortgagee have not been recorded. Therefore, when a third party participates in this secured transaction, the author finds that the law does not have a sufficient basis to protect them. Therefore, finding out and making recommendations on securing obligations by mortgaging third party assets to protect the rights of parties (especially third parties) is necessary.
Determination entity responsible for compensation on damages of minors: current situation and solutions
Liability for compensation of minors (TNBTTHCNCTN) is applied to the subject causing minor damage, and according to regulations, compensation liability arises. Determining the entity causing the damage is not too difficult. Still, the issue of determining the entity responsible for compensation is an obstacle when the 2015 Civil Code stipulates that there are still many problems. For example, how is compensation handled for a minor under 15 years old who is causing damage and has no parents, guardians, or personal property? On the other hand, the 2015 Civil Code has "forgotten" the school's responsibility when minors from 15 years old to under 18 years old cause damage while studying and under school supervision. If the school is at fault while supervising and educating minors and causing damage, then the 2015 Civil Code does not stipulate their responsibility. Therefore, continuing to add legal terms, amend and supplement some legal regulations, and ensure the principles of equality, strictness and fairness of the law related to NCTHCNCT is urgent work.

Limitations of the law in determining contributions in the joint property of spouses during divorce and some proposed remedies
In a divorce case, the occurrence of disputes relating to the common property of the spouses is unavoidable. While social context popularizes a setup that only a husband (or wife) engages in productive activities to generate financial gains and assets for the whole family; and the wife or husband takes on the tasks of the housework, the contributions of the wife (or husband) has not been sufficiently recognized if during a divorce case, the split in common property is necessary. This problem has been governed by the laws of marriage and family of Vietnam. However, there are too many gaps in addressing this issue as revealed in the analysis, synthesis and evaluation of the provisions of the Law on Marriage and Family 2014 and other relevant legal documents. From there, the author explores the limitations of the law in determining the contribution of spouses in common property when divorced as well as proposing some measures to address these limitations

Some problems with trespassing on other people's dwellings and suggested solutions
In recent years there have been many cases of trespassing on other people's accommodation. In addition, this is the cause of crimes caused by intentional acts committed by subjects. Here is another case where people lack knowledge of the law, leading to the commission of criminal acts. The current Penal Code has specific provisions concerning this crime in Article 158 on acts and sanctions that are aimed at punishing, educating, and deterring subjects. Although there have been criminal sanctions, the application of the provisions of Article 158 of the Penal Code still has problems such as: there is no legal document guiding what another person's accommodation is; which acts are considered acts of infringement on accommodation to determine criminal liability; which cases are considered insecurity of social order and safety; and the entanglement in gathering evidence to prove the offense. The research work is based on the method of analyzing the law of writing, synthesis and comparison. The study of difficulties and obstacles contributes to the uniform application of the law when dealing with crimes that infringe upon other people's accommodation and improves the effectiveness of the practical application.

Studies on building a natural sunscreen formula with titanium dioxide and zinc oxide
The best way to prevent UV damage to the skin was to use sunscreen. There were many types of sunscreens, but they were formulated with chemical ingredients. Natural sunscreens were still less popular. So, the study was to develop a natural sunscreen formula from titanium dioxide and zinc oxide. By this experimental method, the natural sunscreen had been formulated with titanium dioxide, zinc oxide, shea butter and almond oil. The natural sunscreen with 2% TiO2, 6% ZnO, 20% shea butter, 4% almond oil and 9% beeswax were combined for a defined SPF value of 50,6. The product was milky white, soft, smooth, dense and uniform. The pH value was 6,08. S. aureus, P. aeruginosa and C. albicans, was not detected and aerobic microorganisms were below 102 cell/cfu. Heavy metals such as arsenic, lead, and mercury was not detected. The product did not damage the skin. The results also showed that this product followed the 7/VBHP-BYT circular on cosmetic management.

Microsurgery characteristics, antioxidant and α - Glucosidase inhibition activities of Ipomoea pes - caprae
Ipomoea pes - caprae is a wild plant grown on beaches in Southeast Asian countries so they are easy to find. Currently, only some parts such as flowers, fruits, seeds, and roots of Ipomoea pes - caprae have been studied to show quite good antioxidant potential. The study aimed to investigate the microsurgical characteristics, chemical composition and some biological activities of Ipomoea pes - caprae extracts. Research results showed that leaf microsurgery has an upper epidermis, thick tissue, libe, wood and lower epidermis. Body microsurgery has epidermis, lamina propria, soft tissue, hard tissue, libe, wood and soft tissue. The main chemical components of Ipomoea pes - caprae are polyphenols, carotenoids, anthraquinones, saponins, tannins, polyuronic compounds. The DPPH free radical scavenging test showed that the antioxidant activity of 50% ethanol extract was the highest with IC50 = 7.95 ± 0.35 µg/mL. The extracts also showed strong α-glucosidase inhibitory activity in which aqueous extract was the strongest with IC50 = 7.92 ± 0.05 µg/mL. However, the 96% ethanol extract had negligible α-glucosidase inhibitory activity.
