중소영세 섬유업체 근로자들 1,138명을 대상으로 자기기입식 설문조사를 하여 근로자의 보건관리형태에 따른 산업보건에 관한지식, 태도 및 실천의 정도를 비교하고 다음으로는 집단보건관리군 694명만을 대상으로 하여 집단보건관리 기간이 지식, 태도 및 실천에 미치는 영향을 알아보고자 하였다. 1. 보건관리형태에 따라서 산업보건에 관한지식, 태도 몇 실천의 평균점수는 개별보건관리군에서 모두 높았으나 실천의 점수만 통계적으로 유의한 차이를 보였다. 그러나 비교하고자 하는 두 집단간에는 대부분의 일반 특성이 유의한 차이가 있으므로 이를 교정하고자 중회귀분석을 실시하였다. 중회귀분석 결과, 지식에 유의한 영향을 미치는 변수는 연령, 교육 수준, 총 근무기간이었고, 태도에 유의한 영향을 미치는 변수는 연령, 교육수준, 결혼상태였다. 실천에 유의한 영향을 미치는 변수는 성, 연령, 교육수준, 결혼유무, 총 직장근무기간이었다. 연구의 목적인 보건 관리형태별로 비교시는 지식, 태도 및 실천에 미치는 영향은 집단보건관리군의 경우 지식의 평균점수가 조금 높았을 뿐이며, 태도 및 실천의 점수는 낮았다. 그러나 두 가지 보건관리형태에 따른 유의한 차이는 없었다. 2. 집단보건관리군에 국한하여 분석한 결과, 보건관리기간(개월수)은 대상 근로자들의 산업보건에 관한 지식, 태도 및 실천 모두에 유의한 영향을 미친다고 할 수 있다. The first purpose of this study was to compare the mean Knowledge, Attitude & Practice(KAP) scores concerning major occupational health between two types of occupational health management in small & medium-scale textile factories. Sample number was 1,138 workers. In small & medium factories with 300 workers or less, they have two alternatives for occupational health management ; Individual Health Management or Vicarious Health Management. The second purpose was to determine if there was a relationship between duration of Vicarious health management and mean KAP scores for 694 workers from the Vicarious Health Management group. We used self-administered questionnaires for measuring KAP. The results of this study were; 1. There was significant difference concerning all socioeconomic & occupational variables (gender, age, education level, marital status, Blue/White collar, working duration of present factory, working duration of total factories) except for shift. 2. There was no significant difference of mean scores of Knowledge and Attitude between the Individual Health Management Group and the Vicarious Health Management. But, the mean score of Practice was significantly different. 3. According to multiple regression analysis, the mean score of Knowledge significantly increased with age, education level, working duration of all factories increased. The mean score of Attitude significantly increased with age, education level and married. The mean score of Practice significantly increased with age, education level, working duration of all factories, married and men. 4. In conclusion, The type of Health management did not significantly affect the mean KAP scores concerning major occupational Health problems. 5. But, the Duration of Vicarious Health management significantly increased the mean KAP scores.

School dropouts not only forfeit the opportunities of students for education but also deprive themselves of their opportunities for proper the way of society, giving rise to actions of maladjustment in social life. Such actions increase the risk of ultimately resulting in misconduct and criminal behavior. To prevent and guide dropouts, not only is to aid in the students' futures but also it is critical for social management and development of human resources. Through research, It was found that the dropout rate is affected by such factor as the students' family atmosphere, a residential district, grades, and experience of leaving home. In terms of area, dropout rate was higher in schools located in cities than in schools located in rural areas and it was that at the time of dropping out, the characters of the student was generally lower grade than average, runaway experience, unstable family environment, family financial troubles, and lower school career degree of parents than those of high school graduate. The maladjustment to school life of dropout students is largely due to excessive competition for university entrance exam, a rigid rules of school and neglect of their individual need. Therefore, Dropouts is in need of different alternative education with existing public school rather than simply returning to school and government and office of education have to effort for development and reinvigoration of alternative education. In order to develop and reinvigorate alternative education, government and office of education have to prepare policies for resolving the matters of occurrence in relation to alternative school such as lack of understanding of alternative education, poor educational surroundings owing to lack of funds, social bias, lack of alternative school in city, inefficient management system, organizational restrictions, and excessive controls to institutionalized alternative school. As plan for resolving the problems, first, it is to reinvigorate a mutually cooperative relationship between exiting public school and alternative school through reinforcement of support systems and professionals aided in school adjustment of students. Second, through qualitative evaluation to alternative school, a discriminative support of finance and a more flexible administration should be encouraged. Third, policies should be prepared for a public relations of alternative Finally, establishment of alternative school in city should be expanded and standards for academic recognition need to be diversified.

This study was carried out to assess work ability of manufacturing workers and managerial workers. Subjects were 446 manufacturing workers and 278 managerial workers employed in Gumi industrial complex and the observation period was for 1 month(February to March), 1995. In this study, as a questionnaire for the assessment of work ability, we used the Work Ability Index(WAI) which was developed by Institute of Occupational Health in Finland. Major findings obtained from this study were as follows ; WAI was poor in lower economic condition, shift work, irregular diet group(p<0.05). There were no evident trends of WAS in sex, educational level, obesity index, exercise, smoking, and alcohol drinking. In the groups of sensitive to perception of stress, other industrial classification except textile and electronics, the more than 9 hours work, the evident trends of poor WAS were observed(p<0.01). In the groups of $30\sim39$ years old, $40\sim49$ years old, unmarried, high school, shift work, standard body weight, and regular .diet, WAI between manufacturing workers and managerial workers was significantly different(p<0.01) and WAI of managerial worker was worse than that of manufacturing worker.

We studied cases of using the priming effect to prevent user attrition in the early stages of entry into mobile Role-Playing Game(RPG), classified games by type, and analyzed them. As a result of selecting and studying Sixty-eight games for research, the games under study had a device in place so that positive elements that can be experienced in the latter half of the game could be experienced in advance at the tutorial stage at the beginning of entering the game. Researchers named these devices Pre-Experience System, created a classification diagram of Pre-Experience System for each system feature, and described what characteristics each had. In addition, the type of Pre-Experience System was classified into Single Character Experience Type, Multiple Character Operation Experience Type, Large-Scale Battle Experience Type, and Boss Battle Experience Type. Depending on whether Pre-Experience System was manipulated, it was classified into Direct Experience Type and Indirect Experience Type, and the Boss Battle Experience Type was classified into Battle Success Type and Battle Failure Type.

As Game Business Model is advanced, the size of the mobile game market continues to increase, but in the process, games that induce payment for IAPs (In App Purchases) including excessive probability items are increasing. As a result, the billing fatigue felt by users is also increasing. In addition, as the controversy and regulations on probability-based items intensified, the emergence of new game BMs became urgent, and it is Battle Pass that game companies pay attention to as a new alternative to overcome these problems and provide useful BM to users. In this paper, the top 100 mobile game sales in Korea were surveyed, and the status and cases of Battle Pass application were analyzed and categorized. Through this, we present a guide so that game companies who want to introduce Battle Pass can design a Battle Pass BM that fits their own content characteristics and structure. However, since the research subject of this thesis is limited to Korean games, we will analyze the global battle pass application cases through the following thesis.

본 실험은 plain yoghurt에 배추즙의 혼합비율을 달리하여 frozen yoghurt mix의 pH, 점도 및 보수력과 frozen yoghurt의 유산균 수, 색차, 물성 및 관능검사 결과를 비교 검토하여 frozen yoghurt 제조를 위한 최적의 배추즙 혼합비율을 알아보기 위해 실시하였다. Frozen yoghurt mix에 사용된 plain yoghurt의 당질과 유기산의 함량을 HPLC로 분석하였던 바 당질은 lactose와 sucrose의 함량이 높은데 반해 galactose와 glucose의 함량은 낮게 나타났고, 유기산은 모든 처리에서 유산과 구연산의 함량이 비교적 높은 경향이었다. Frozen yoghurt mix의 pH, 점도 및 보수력은 배추즙의 첨가수준이 높을 수록 낮게 나타났다. 색차는 저장기간 간에는 큰 차이가 없었으나 배추즙 첨가수준간에는 다소 차이가 있었다. Frozen yoghurt의 hardness는 배추즙의 첨가수준이 증가할수록 높게 나타난 반면 cohesiveness나 elastisity는 낮게 나타났다. Frozen yoghurt의 관능검사 결과는 풍미는 배추즙 5와 10% 첨가구에서 높게 나타났고, 조직 및 외관은 배추즙 첨가구에서 무첨가구에 비해 낮게 나타났으나 차이(p<0.05)가 없었다. This study was conducted to find the feasibility of Chinese cabbage juice for making the frozen yoghurt by analyzing the carbohydrates and organic acids contents, pH, viscosity, water holding capacity and the number of lactobacillus bacteria in the frozen yoghurt mix, and the chromaticity, physiology and sensory evaluation in the frozen yoghurt. In the frozen yoghurt mix, the carbohydrates and organic acids produced in plain yoghurt which are the main sources for the frozen yoghurt showed that the amount of lactose and sucrose was higher than any other carbohydrate sources, whereas the lactic acid and citric acid were trended higher than any other organic acid sources. The pH, viscosity and water holding capacity of frozen yoghurt mix were decreased by adding Chinese cabbage juice. In the frozen yoghurt, the chromaticity showed not so much difference in different frozen storage periods, but differences among the Chinese cabbage juice levels. The reology of frozen yoghurt increased by increasing the Chinese cabbage juice level, whereas cohesiveness and elasticity decreased. In the result of sensory evaluation of frozen yoghurt, the flavor showed high at 5% and 10% level of Chinese cabbage juice, but texture and appearance of the products showed lower than that of the control(p<0.05).
