현재 베트남에는 바다에서 직접적으로 소금을 얻어내는 방법 이외에는 다른 방법이 아직 발견되지 않고 있다. 베트남은 27개의 성과 도시를 지나는 해변이 3,000km 이상이며, 그 속에는 26개의 성이 소금을 생산한다. 소금 생산은 전통적인 직업이며, 베트남에서 가장 오래된 직업 중의 하나이다. 최근 10년 동안 매년 전국의 평균 소금 생산량은 약 650.000 톤으로, 최저 생산량은 550,000톤이며, 최고 생산량은 800,000톤에 이른다.

To develop multi-tier model or distributed architecture based distributed application needs to consider various aspects such as division of role between web-designer and software developer, defining entity and its usage, database connection and transaction processing etc. This paper presents DONSL(Data Server of Non SQL-Query) architecture that provides solution to above aspects through web-tier object modeling. This is the architecture that guarantees the transaction processing and performance between web-tier and DBMS through simplified usage of query logic property. This new conceptual framework also solves enterprise site implementation problems simplifying tier, and removing DAO(Data Access Object) and entity.

In this study we review the representations used for emphasizing the significance and requirement of mathematics in Chinese and Korean mathematics text(算學書). Especially, we study four terms; first 六藝之一(육예지일, one of the six arts), second 伏義(복희, Fuxi) 周公(주공, Zhougong) 孔子(공자, Kongzi) 孔門(공문, Kongmen), third 道(도, dao) (색, ze) 微奧(미오, weiai) 精微(정미, jingwei), forth 經世之實用(경세지실용, usefulness in the real life). Through these representations that can be seen in the many mathematics text, we consider the author's efforts to improve the mathematics.

The article analyzes the impact of factors affecting the internal control system of chemical enterprises in Vietnam, providing more empirical evidence on factors affecting the system of internal control. Research data is collected in the form of face-to-face interviews and email interviews with managers and employees working in different positions, managers at all levels, chief accountants, and accountants of 52 chemical enterprises in Vietnam. The survey results collected 310 questionnaires. After eliminating the invalid questionnaires due to many blank cells, the authors chose to use 297 questionnaires. Quantitative research was carried out with SPSS 25 software. Research results show that Business Strategy, Organizational Structure, Organization's perception of the instability of the external environment, and Organizational culture are the factors that positively affect the internal control system of chemical enterprises. This can be explained that, for chemical enterprises, Business strategy, Organizational structure, Organization's perception of the instability of the external environment, and Good organizational culture will positively impact the internal control system of chemical enterprises. Based on the research results, the authors have proposed recommendations to enhance the effectiveness of the internal control system of chemical enterprises in Vietnam, thereby contributing to improving the performance of enterprises in the chemical Vietnamese.

This work is the first to apply nonlocal theory and a variety of deformation plate theories to study the issue of forced vibration and buckling in organic nanoplates, where the effect of the drag parameter inside the structure has been taken into consideration. Whereas previous research on nanostructures has treated the nonlocal parameter as a fixed value, this study accounts for its effect, and finds that its value fluctuates with the thickness of each layer. This is also a new point that no works have mentioned for organic plates. On the foundation of the notion of potential movement, the equilibrium equation is derived, the buckling issue is handled using Navier's solution, and the forced oscillation problem is solved using the finite element approach. Additionally, a set of numerical examples exhibiting the forced vibration and buckling response of organic nanoplates are shown. These findings indicate that the nonlocal parameter and the drag parameter of the structure have a substantial effect on the mechanical responses of organic nanoplates.

This paper examines Jang Hyeongwang's cultural awareness and the way of practice by focusing on his spirit of humanities in relation to the understanding of territory and bibliographic materials. In fact, this starts from conflicting evaluations on Jang Hyeongwang's way of learning in the field of Korean history. Jang Hyeongwang emphasizes realization of humanity, which is considered as basic framework of culture. He claims the indivisibility of Dao(道) and culture(mun文) by arguing that almighty principle of Dao manifests itself through phenomena of culture. In other words, Dao is the root of culture and, at the same time, culture is the necessary element of making Dao valuable. Furthermore, he insists that realization of human culture is the gist of manifesting the pattern of nature. In this vein, the roles of human beings are so important in creating humanistic civilization. He considers all kinds of human affairs as the contents of humanistic culture, which are contained in six classics. Especially, He says that the moral is reality of human culture and that literature is a literal expression of humanistic spirit. Thus, he criticizes that there are literatures without moral practices. He pays a special attention to his indigenous culture. He links the cultural understanding of geography, which is the foundation of realizing humanistic spirit, to awareness of Korean territory and grasps the territory in the light of topography of geographic power. Thus, he defines it as "Central Field" which bears comparison with China (middle kingdom). With the positive understanding of his country, he insisted that Korean indigenous culture and custom are as much advanced as China and was so proud of the moral characters and norms that Korean people had formed so far. Moreover, Jang truly exhibited affection to Korean literature, which had formed through Korean history. Kim Hyu, one of his students, activates Jang's will to preservation of Korean culture. Over twenty years, Kim completed Collected Record of Korean Literatures(haedong munhon ch'ongnok 海東文獻總錄). Actually, he started the preparatory works for compiling them. We should keep in mind that this compilation was completed following Japanese Invasion of Korea in 1592. It means that he has cultural awareness of preserving Korean literal heritages. Hence, it can be evaluated as the results of the enhancement of national studies. We have seen that He truly highlights realization of humanistic spirit by insisting the practices of moral values. In fact, his mind is linked to genuine affection to Korean territory, culture and literatures. Such affection can be paraphrased as moral awareness of humanity and its practices. In conclusion, his humanistic spirit should be understood as strong belief on universality of human morality. His cultural awareness of homeland and the will to practices should be considered as cultural pride of Korean intellectual traditions rather than following Chinese culture blindly.
