Billiards is a fun and popular sport, but both route planning and cueing prevent beginners from becoming skillful. A beginner in billiards requires constant concentration and training to reach the right level, but without the right motivating factor, it is easy to lose interests. This study aims to induce interest in billiards and accelerate learning by utilizing billiard path prediction and visualization on a highly immersive augmented reality platform that combines a stereo camera and a VR headset. For implementation, the placement of billiard balls is recognized through the OpenCV image processing program, and physics simulation, path search, and visualization are performed in Unity Engine. As a result, accurate path prediction can be achieved. This made it possible for beginners to reduce the psychological burden of planning the path, focus only on accurate cueing, and gradually increase their billiard proficiency by getting used to the path suggested by the algorithm for a long time. We confirm that the proposed AR billiards is remarkably effective as a learning assistant tool.

This study investigated the perception of the learning-workers' organizational effectiveness. They participate in the degree-linked work-learning parallel system. As a result, the turnover intention and job performance were higher than those of general office workers, and organizational commitment was lower. In addition, the higher scholastic year and grades, the higher job satisfaction. the higher grades, the lower burnout. specially the 2nd, 3rd, and 4th graders showed higher turnover intentions than the first grader. The results of the survey of (dis)satisfaction factors of learning workers also show that OJT management in the field should be strengthened rather than OFF-JT education in universities. This paper suggests that companies participating in the work-learning parallel system need higher-level management in aspects such as educational supports, personnel management, and OJT management as well as competency development of learning-workers. It shows that supplementary measures are needed for learning time and learner management of participating companies.

This research is to make the identity of the two models clear by reviewing the similarities and differences between Social Model of Disability from U.K. and Independent Living Model from United States. Research results are as follows. As for differences, Social Model of disability intended to change disability paradigm by focusing society itself as the cause of disability rather than individuals, however Independent Living Model stressed on the freedom and control through disabled people's life with self-advocacy group and personal assistants. As for similarities, there are self-representatives, social responsibility for disability, alienation of people with intellectual disabilities at the initial stage, background in legislating Disability Discrimination Acts in both countries. This result has its significances because it shows theoretical framework which make it possible to review further how disability practice and movements understand the two models regardless of their real contents and how the two affected the induction and proceeding of Korean Discrimination Act and Independent Living Paradigm in the Disability Welfare Act.

Turnover is an important topic in the labor market, and recently, while various generations work together, it is difficult to manage the organization due to friction between generations. The purpose of this study is to analyze the mediating role of workplace satisfaction in the relationship between personal-level variables (future prospects, life satisfaction) and job-level variables (major-job level, job satisfaction) by generation on intention to leave. To this end, the 22nd Korea Labor Panel Survey was used to select related variables, and the mediating effect was analyzed using SPSS. The main results are as follows. First, it was found that workplace satisfaction plays a complete mediating role in the relationship where individual-level variables affect turnover intention. Second, it was found that workplace satisfaction plays a partial mediating role in the relationship where job-level variables affect turnover intention. Third, in Generation Z, unlike other generations, only the variable of workplace satisfaction at the job level had a significant effect on intention to leave, and workplace satisfaction was found to play a partial mediating role.

Although jobs in the employment service sector have been continuously expanding over the past 20 years, many in the labor market point out that the signaling and selection functions of job counselor qualifications are deteriorating because job counseling and psychology were developed mainly in the early 2000s. Therefore, in this study, a survey was conducted on current employment service workers on the establishment and improvement of employment service professional qualifications. According to the data analysis, employment service workers lack the current level of competence compared to their importance in all their jobs, and there is a limit to taking charge of all the expanded employment service jobs such as corporate support, administrative management, and labor market program planning and execution as a single job counselor. As for the direction of reorganization of employment service-related qualifications in the future, more than half agreed to establish new qualifications. Similarly, more than half of the respondents wanted to strengthen the qualifications of existing job counselors related to employment services.

The purpose of this study is to develop a competency model that enhances the management capabilities of vocational training institutions and to identify the priorities of educational needs. After reviewing prior studies to tentatively establish a competency model, a training needs assessment was conducted in the field using this model. Data for the analysis were collected through a survey conducted among vocational training institutions. Following the needs assessment, a new management competency model for vocational training institutions was formulated, comprising six competencies and 26 competency dimensions, by eliminating the dimensions considered relatively less important. The competency model developed through this study is anticipated to be utilized in creating management education programs for directors of domestic vocational training institutions.

This study conducted an analysis of the changes in social work fields, focusing on the 'generational differences' after the COVID-19. As a result of the study, various opinions were presented in two areas: experience and perception of social workers and requirements of social workers. Social workers in their 20s had many requests for improvement of the current working environment and the Local Government and the Association, and those in their 4~50s had many comments about the working environment. Based on these research results, this study proposed the following practical and policy improvement measures. First, it is necessary to improve the low level of salary, work conditions and environment. Second, a safe work environment is required. Third, it is necessary to pay attention to the changed perceptions of social workers and make efforts to match them.

This study analyzed the work experience of social workers employed in social welfare facilities in Seoul. We investigated key variables, including working conditions, job characteristics, workplace violence, work-related stress, and burnout experiences. Additionally, we utilized word cloud analysis to identify the primary opinions and experiences of social workers. The results showed that social workers' salaries were generally low, and there was dissatisfaction with the promotion and compensation systems. We also found that social workers pointed out issues related to time shortages, poor physical environments, and inadequate equipment. The analysis by institution type revealed that social workers in public institutions reported high job intensity and low satisfaction with their working conditions. Based on these findings, we propose policy and practical suggestions to improve the work environment of social workers.
