  • We proposed an embedded capacitor with the unique electrode structure, which electrodes are located on the same plane and dielectric gap was formed by electrodes. We named it 'Gap type EC', and it was analyzed by the FEM(Finite element Method) program tool. The resonant frequency of Cap type EC was obtained at more higher frequency region. Also, resonant frequency was changed with the magnitude and thickness of electrodes. The Gap type EC with the dielectric gap of $50{\mu}m$ showed capacitance density of $55pF/cm^2$. This value is the higher than that of conventional EC. So, we concluded that the Gap type EC can be a good candidate for high frequency decoupling.

  • Objectives: The purpose of this study is to identify the effects of dental hygienists' cooperation and compensation satisfaction on job embeddedness through positive psychological capital, and to provide basic data on ways to improve the welfare of dental hygienists and the quality of medical services. Methods: From July 1 to 20, 2023, a questionnaire survey was administered to 206 dental hygienists via an online link. SPSS Statistics ver. 22.0 was used to conduct the frequency analysis, t-test, one-way ANOVA, Pearson's correlation coefficient, multiple regression analysis and hierarchical multiple regression. Results: Factors influencing dental hygienists' job embeddedness were type of compensation satisfaction (β=0.362, p<0.001), intangible compensation satisfaction (β=0.190, p<0.001), cooperation between dental hygienists (β=0.178, p<0.05), and age (β=0.112, p<0.05). Positive psychological capital was found to have a complete mediating effect on work cooperation in the effect of dental hygienists' job embeddedness (p>0.05), and partial mediating effect on compensation satisfaction (p<0.01). As a result of the Sobel test, it was confirmed that it was statistically significant as dental hygienist work cooperation (Z=2.339, p=0.019), dentist work cooperation (Z=1.985, p=0.047), intangible compensation satisfaction (Z=2.286, p=0.022), and type compensation satisfaction (Z=1.980, p=0.048). Conclusions: In order to improve the work environment of dental hygienists, develop programs to improve positive psychological capital, secure access to education, and various related studies are needed.

  • Purpose - Korean agriculture is facing internal and external environmental changes and the need for secure stable outlets. Active participation and mutually beneficial cooperation between enterprises and agricultural is necessary for a win-win situation. This study investigates the case for distribution cooperation and a cooperative system. To respond to the diverse needs of consumers and market reclamation, there is a need to analyze and categorize distribution cooperation. Research design, data, and methodology - A literature study, relevant interviews with enterprises, and meetings with local government practices were conducted. A survey frame was derived through the participation of agricultural enterprises and distribution cooperation models were categorized identifying win-win cooperation and best practices. It was organized on the basis of six best practice examples of distribution cooperation between industry and agricultural sectors, divided into three types: opening distribution channels, exporting cooperation, and developing new products. Results - An innovation management system that can adapt to environmental changes and problems of agriculture is necessary. A company has to supply high-quality agricultural products reliably to meet the preferences of consumers by introducing products that promote domestic market differentiation. In addition, consumers are choosing a variety of products that may include not only high quality products but also local products and safe products. The main areas of cooperation are the direct provision of agrifood raw materials to consumers. Next, would be to help agricultural sectors distribute and pioneer international markets. The ideal step for distribution cooperation is the joint investment in new products by business and agriculture. Conclusions - Agriculture and win-win cooperation with enterprises is in an early stage of social contribution. To implement a distribution cooperation model between business and agricultural sectors, it is crucial to establish a structured support system including joint councils. Additional requirements include strengthening agricultural capacities, creating a legal basis for provision, and producing a win-win cooperation environment. The promotion of win-win cooperation and agricultural enterprises needs to exist in various forms in order to establish a different type of incentive system.

  • This study was attempted to understand experiences of the users of natural family planning(NFP) by applying Q-methodology. 37 statements were used to Q population through literature research and interviews. For the P sample. I interviewed personally 30 people who had taken a lesson in NFP for over 6 months and had been using and experiencing it autonomously for more than 2 years so far, and asked them to Q-classify the statement cards in order of the degree of approval, from the one they most approved to the one they least approved. Data were coded and input into a computer and were analyzed using QUANL PC Program. In this study, I discovered 4 types of experiences by the users of NFP and named them each according to their features: the first, a type of mutual control with morality, the second, a type of the pursuit of mutual -cooperation, the third. a type of the pursuit of conviction. and the fourth, a type of the perception of health management. The first type said that NFP was a good contraceptive way in which no drug or devices are used, that the husband's cooperation was needed, and that they became able to control sexual desire with morality. The second type perceived that continuous efforts were required to put NFP in practice, that the, husband's cooperation was essential, and that dialogues between husband and wife were also necessary to use it, and as such they regarded mutual cooperation between husband and wife as highly important. On the other hand. the third type perceived that one's conviction played a big part, that knowledge of physiological changes was useful and the ability to sense physical changes improved. and that one's willpower was important. and thus they regarded one's own willpower as most important. The fourth type reported that this method was a good way to control pregnancy and should be taught about at the beginning of sex education. and thus they were emphasizing the importance of NFP as a helpful way to manage one's health. 1. therefore, intend to provide the following suggestions based on the result of this study. 1) It is necessary to develop a program that allows NFP to be applied to sex education program. 2) It is necessary to analyze factors that affect the execution of NFP. 3) It is necessary to analyze causes of failure of those who fail to execute NFP.

  • International research cooperation is emerging as one of the strategies for improving research performance. Therefore, in this study, through the analysis of research reports on the theme of international research cooperation, the subject and issues of international research cooperation were identified and the characteristics of these studies were confirmed. To this end, related report data were constructed, statistical data analysis and big data analysis of the data were performed. Considering the current international research cooperation network, it is necessary to conduct international research cooperation centered on developing countries while paying attention to the increase in China's proportion of international research cooperation. Second, it is necessary to emphasize the importance of international research cooperation in various countries, including developing countries, in that the interdependence of research between countries increases and the citation index of actual joint research is higher. Third, it can be seen that the subject field in which international research cooperation can be activated may vary depending on the type of support project. Therefore, it suggests that in order for international research cooperation on more diverse topics to be carried out, projects supporting them must also be diversified.
