This study investigates the effects of depression and self-esteem on elderly mental health, quality of life, and life satisfaction, considering South Korea's transition to a super-aged society by 2025. The research aims to propose integrated strategies for effective management of these factors. The findings reveal that depression and self-esteem significantly impact elderly mental health, quality of life, and life satisfaction. Increased depression is associated with decreased quality of life and life satisfaction, while higher self-esteem is linked to reduced depression. Additionally, a reduction in social relationships is found to exacerbate depression and diminish self-esteem. To enhance the quality of life and life satisfaction for the elderly, it is crucial to manage depression and self-esteem systematically and continuously. Thus, an integrated, nationwide approach is needed for effective management.

The purpose of this study is to analyze various issues that may arise from the recent deregulation of telemedicine implemented by the government, propose initiative preparations for the implementation of telemedicine policies, and suggest implications for the basic conditions and direction of the deregulation of telemedicine. Recently, deregulation policy cases in telemedicine include that designation of a special zone for regulatory freedom in Gangwon Province, allowing physician-patient telemedicine and telephone counseling and prescription cases in the COVID-19 crisis. There are four main issues that could arise with the deregulation of telemedicine: safety, effectiveness, differences in access to health care and the economic industry, and legal responsibility. As a initiative preparation, this study proposed a pilot project for telemedicine and enhanced support for face-to-face care complementary tools, vitalizing remote co-operation, policy model that do not disrupt the medical delivery system, and legal maintenance. In conclusion, as a suggestion of basic premise and direction in the implementation of telemedicine deregulation, the implementation of initiative measures to address issues concerning telemedicine, the review and regulation of conditions to be considered in the implementation of telemedicine, and the establishment of a close communication and cooperative sturcture with medical providers.

This study was conducted to detect metabolic syndrome risk factors and gender difference in adults. 18,616 cases of adults are collected by Korea Health and Nutrition Examination Study from 2016 to 2019. Using 4 types of machine Learning(Logistic Regression, Decision Tree, Naïve Bayes, Random Forest) to predict Metabolic Syndrome. The results showed that the Random Forest was superior to other methods in men and women. In both of participants, BMI, diet(fat, vitamin C, vitamin A, protein, energy intake), number of underlying chronic disease and age were the upper importance. In women, education level, menarche age, menopause was additional upper importance and age, number of underlying chronic disease were more powerful importance than men. Future study have to verify various strategy to prevent metabolic syndrome.

This study is a study to secure accessibility in isolated, neglected and underdeveloped island areas. Theoretically explored ways to utilize UAM(Urban Air Mobility), which has recently attracted attention. This is a study for the important accessibility that is connected to the basic life of island residents. In particular, sufficient preparation time is needed, such as the selection of topics necessary for the change of the transportation service system for access to the island area, the public debate process, and the trial service period. Therefore, the secondary purpose of this study is to provide relevant basic data.

This study was performed to study the factors appear to SMEs and how differently depending on the worker ranks at the convergence age. Additionally, numerous studies and results on the factors which affect the organization's performance was to individually different approach to integrated. Especially venture was divided by a factor of enterprises and transformational dynamics factors and commutative Dynamics factors and approaches in terms of the impact transformative dynamics of which factors are organizational commitment and job satisfaction. A transformational dynamism to the four factors were such as mission and strategy, CEO Leadership, Manager, leadership, organizational culture variables. The study was based on theoretical models of organizational development, Burke and Litwin (1992). They were classified as managers and production workers. By obtaining data from employees 630 people engaged in a total of nine manufacturers were analyzed. The average variable based on the organization's Burke and Litwin (1992) theory of transformational variables is one that Nana was aware of the organizational commitment, and job satisfaction. Correlation analysis transformational dynamics variables're having an impact on job satisfaction and organizational commitment, job position is found to have moderating effects.

This study deals with the technical approach related to the protection of digital video contents copyright, which has currently become a major issue in the digital contents market. With the production and distribution of digital video contents rapidly increasing, various policies and technical approaches are being made in relation to the protection of intellectual property rights. The technical approach from a DRM (Digital Rights Management) perspective was made from various angles, but its limitations have also been exposed in terms of convenience and quality. In this study, rather than the existing encoding certification and watermark technologies, it introduces technical approaches from a content-based copy detection method, while suggesting a copy detection method using the representative color sequence. In particular, this study takes into consideration the distribution environment of the domestic video market and deals with the technical approach in a direction that can control the illegal distribution of high quality videos.

This study intends to figure out the relationship between autonomy and achievement motivation of the university players. For this purpose, Survey was performed to Seoul and Metropolitan area's 25 sports 396 Players., And using SPSS 18 and AMOS program descriptive statistics, exploratory factor analysis, confirmatory factor analysis, reliability analysis were conducted. Based on purified data through the process, the relationship between autonomy and achievement motivation was verified with correlation analysis and regression analysis. As a result, autonomy was recognized by male player higher than female player, and in goal-orientation of the access tendency of achievement goal orientation, male player showed higher scores. And in mastery-avoidance of avoidance, female player showed higher scores and in performance-avoidance, male player showed higher scores. According to regression analysis, autonomy affects mastery-approach and achievement goal orientation of the performance-approach.

This study evaluates the convergence radiation protection performance by measuring the PSNR(peak signal-to-noise ratio) values of the image J in the image evaluation program based on increased relative to this exposure of radiation workers.The aim of this study was to evaluate radiation protection performance of apron for design of it's basic information. Method was used to PSNR of Image J program and good condition apron was more than 27dB, the PSNR value of poor condition apron appeared to be less than 24dB. The result is the normality were satisfied distribution and T-test values were statistically significant with p<0.001. Results of evaluation of the performance protective apron through the more easily accessible experimental conditions and methods in the clinical was confirmed distinctly different. in order to reduce the radiation exposure we need to evaluate convergence protection performance and to be having a good performance apron.
