The purpose of this study was to investigate the mediating effects of stress coping strategy on the relationship between academic burnout and school adjustment in Korea adolescents. A survey was conducted using a convenience sample drawn from 1,232 students from junior high schools in Kunggi Province. Data were analyzed using SPSS package program. The survey results showed that 44.6% of students are dissatisfied with their own academic grade. Antipathy and cynicism showed the most impact on academic burnout. In addition, academic burnout was negatively related with school adjustment. Especially academic burnout exerted inverse relationship with school adjustment, whereas problem oriented and seeking social support coping positively influence on school adjustment. Problem oriented and seeking social support coping partially mediated the relationship between academic burnout and school adjustment. The results indicate that improvement of active stress coping is important to prevent the symptoms of academic burnout and to increase the school adjustment.

Many researches have been published about the numerous factors related to the chewing ability of implant prosthesis. Most respective studies have concluded that the chewing ability of implant prosthesis is mostly fine compared to other type of prosthesis. However, some patients are not satisfied with their chewing ability of implant prosthesis. Therefore the neurologic factor, one of the factors related to dissatisfaction of chewing ability was reviewed in this study to understand the mechanism of action of mastication. Data was searched using the keywords; 'implant chewing ability, masticatory ability' in Pubmed database and reviewed. Definitions of chewing ability, factors of chewing ability are reviewed and the neurologic factor, one of the factors influencing on chewing ability, is reviewed. Mechanoreceptor of Periodontal ligament(PDL) is providing the mastication information to brainstem. Due to the absence of mechanoreceptions of PDL in implant, masticatory ability is decreased especially when chewing hard food. Masticatory muscles and mechanoreceptor in TMD may compensate the lack of mechanoreceptor of PDL in implants. Furthermore sensitivity of nerve fiber around peri-implant tissues may support the mechanoreception and sensory reaction in the implant mastication. However, further studies should be conducted to prove the relationships between neurologic factors and mastication.

The purpose of this study was to collect information for the improvement of sewing practice classes and to draw implications by carrying out an investigation into the perception and needs of 185 students in the first grade of high school for sewing practice classes. The results of the study are as follows. First, most of the students perceived that the instructional objectives of the practicum as the utilization in everyday life. The students' perception of the class was moderately positive. In terms of the subfactors, the participation level appeared to be the highest while the comprehension level was the lowest. Also, the utilization level showed the greatest difference between male and female students. The results suggest that female students were more positive in their perception of the class than the male students because of the significant difference in the subfactors of class perception, excluding utility and teaching learning method satisfaction. Second, it appeared that the students were likely to use these skills in everyday life as a result of the sewing practice classes. In terms of the practice content, students preferred working individually in terms of organizing their own projects, making their own selections, and freely deciding the size of their products. This study demonstrated that the students preferred teacher-centered classes when acquiring skills and knowledge and student-centered classes when brainstorming and performing the teacher's role. In terms of instructional management, the students preferred four to six 50-minute long lessons per semester and no group work involved.

The second-hand ship market provides immediate access to the freight market for shipping investors. When introducing second-hand vessels, the precise estimate of the price is crucial to the decision-making process because it directly affects the burden of capital cost to investors in the future. Previous studies on the second-hand market have mainly focused on the market efficiency. The number of papers on the estimation of second-hand vessel values is very limited. This study proposes an artificial neural network model that has not been attempted in previous studies. Six factors, freight, new-building price, orderbook, scrap price, age and vessel size, that affect the second-hand ship price were identified through literature review. The employed data is 366 real trading records of Panamax second-hand vessels reported to Clarkson between January 2016 and December 2018. Statistical filtering was carried out through correlation analysis and stepwise regression analysis, and three parameters, which are freight, age and size, were selected. Ten-fold cross validation was used to estimate the hyper-parameters of the artificial neural network model. The result of this study confirmed that the performance of the artificial neural network model is better than that of simple stepwise regression analysis. The application of the statistical verification process and artificial neural network model differentiates this paper from others. In addition, it is expected that a scientific model that satisfies both statistical rationality and accuracy of the results will make a contribution to real-life practices.

This study empirically identified and sought implications for the degree of desire by film crews to participate in overseas production and the factors affecting them, based on the recognition that the active participation of skilled film crews in overseas production and joint ventures can be an alternative to the poor treatment of domestic film industry sites and the reduction of job losses due to problems with career barriers. In order for respondents to verify research questions, binomial logistic and marginal effects analysis using SPSS and STATA, the data obtained by surveying 402 film crews operating in various areas. The notable findings are as follow: First, about 65%(263 people) of the respondents expressed their desire to participate in overseas activity, indicating that a considerable number of film crews are looking forward to opportunities with overseas productions. Second, major factors that have a positive effect on film crews' need to participate in overseas activities have been found to be professionality, artistic identity, Korean Wave persistence, and career barriers. In other words, the higher the professionality, the more clearly the identity of the artist, the more positive expectations of the possibility of the Korean Wave continuing, and the more serious the problem of career disability, the clearer was the desire to participate in overseas production and joint-work activities.

The present research aimed at investigating the impacts of volunteer activities on self-development and sociability-development. In study 1, the scale comprised of 15 items was developed to measure the meaningfulness of volunteer activities. An exploratory factor analysis was conducted on the data obtained from 428 undergraduates (193 males and 235 females). A confirmatory factor analysis was then conducted on the data obtained from 280 undergraduates (124 males and 156 females). In study 2, the impacts of volunteer activities on 947 undergraduates (461 males and 486 females) were analyzed in terms of self-development and sociability-development. Self-development consisted of self-evaluation, self-esteem, and quality of life. Sociability-development consisted of pother-acceptances, sense of community, and democratic citizenship. The results showed that not more volunteer activities itself but more meaningfulness of those activities had stronger relations with self-development and sociability-development. Finally, a values of the undergraduates internalized for volunteer activities and their levels of self-development and sociability-development expectation were discussed.

A franchise can be said to be the main method of distribution and marketing. It appears to be the future of the retail industry and is one of the world's fastest growing businesses sectors, as many policy reports and research results have acknowledged. Korea's franchise industry began in the 1970s, spread out into many areas (including food services, retail, and the service industry), and has grown by over 10% each year ever since. The industry's influence on the national economy becomes ever greater. Although the size of the franchise industry is expected to grow as it spreads and as the government expands its support, it has not yet attracted much academic interest. Research has so far been very fragmented. The main interest has been the relationship and conflicts between the head offices and the affiliates. No study has yet occurred on whether the concepts of satisfaction and intent to conclude a contract directly affect the success or failure of the affiliates. Few studies have empirically inquired into the demographic characteristics and abilities of the affiliates that significantly affect their results. Domestic franchise industries must prepare to leap from quantitative to qualitative growth. Most important is the need for affiliate headquarters and affiliates to build confidence between them. A friendly and reliable relationship between affiliate headquarters and affiliates will eliminate distrust from the franchise and maintain a healthy franchise system. This study suggests that current and prospective heads of affiliation should concentrate not on attracting affiliates but on investment and techniques of affiliate support. They should work on the reinforcement of brand power, the appropriate affiliate business environment, systematic education/training, taking burdens off the affiliate business persons, consolidating the relationship with the affiliate business persons, marketing mix factors (e.g. products, price conditions, logistics and shipping services, promotion, supervising and supervisor, operation procedures/processes, and material evidence); these all greatly affect the success or failure of the affiliate business. Supporting the affiliates is an important factor that enhances their results and satisfaction and consequently increases the positive recommendations to others and the ratio of recurrent conclusions of contracts, which ultimately generate the growth of the franchises. In addition, it is suggested that prospective franchise founders should make every effort to choose a good head office since the characteristics of the head office greatly influence the success of the affiliates. This study is significant in that it grasps the characteristics of the head office of affiliation and of the affiliates that influence affiliate results in ways not yet academically attempted.
