This study aims at proposing some reform measures for the middle school grouping system in Gwangju Metropolitan City, which is divided 86 middle schools into 10 clusters and 3 school districts. In doing so, it analyzes the present status of educational environment and student walking distance in each school district such as the number of student per teacher, the student density, the school size and the gender ratio in class. And it conducts a survey of 5,363 middle school students, 3,966 parents and 1,007 teachers, also evaluates their satisfaction levels and needs with the student allocation system. As the result of the survey and data analysis, it finds out some problems in some school districts which are gender imbalance in class, the preference for private middle schools and inconvenience in commuting to school. To solve these problems, the study suggests the better alternatives to replace the current system. Firstly, to set up the basic fundamental principles detailed in 3 action plan, which emphasize the adherence to a close-range allocation, the appropriate size of school and class, and the equalization of educational environment. Secondly, to establish the information system for managing the school district in order to be more objective and transparent. Finally, it gives a concrete proposal which divides the 10th school grouping system into the 11th. The result would be expected to ease the gender imbalance and the concentration of private middle schools, to improve the student walking condition to school.

Various websites have been created due to the increased use of the Internet, and the number of documents distributed through these websites has increased proportionally. However, it is not easy to collect newly updated documents rapidly. Web crawling methods have been used to continuously collect and manage new documents, whereas existing crawling systems applying a single node demonstrate limited performances. Furthermore, crawlers applying distribution methods exhibit a problem related to effective node management for crawling. This study proposes an efficient distributed crawler through stepwise crawling node allocation, which identifies websites' properties and establishes crawling policies based on the properties identified to collect a large number of documents from multiple websites. The proposed crawler can calculate the number of documents included in a website, compare data collection time and the amount of data collected based on the number of nodes allocated to a specific website by repeatedly visiting the website, and automatically allocate the optimal number of nodes to each website for crawling. An experiment is conducted where the proposed and single-node methods are applied to 12 different websites; the experimental result indicates that the proposed crawler's data collection time decreased significantly compared with that of a single node crawler. This result is obtained because the proposed crawler applied data collection policies according to websites. Besides, it is confirmed that the work rate of the proposed model increased.

The purpose of this study was to investigate the differences in time use between Korean and American high school students. The data sources were the '2009 Time Use Survey' conducted by Korea National Statistical Office and the '2009 ATUS (American Time Use Survey)' conducted by Labor Statistics Division in the U.S.. 1,734 Korean diaries (1,311 on weekdays and 423 on Sundays) and 321 American diaries (208 on weekdays and 113 on Sundays) from high school students of 15 to 18 years of age were analyzed. Descriptive statistics and t-test were used for the statistical analysis. The time use patterns of Korean students on weekdays and Sundays were different than those of their American counterparts. On weekdays and Sundays, the sleeping time of Korean students was 2 hours less than the time of their American counterparts. Koreans studied more, nearly double the time of their American counterparts on weekdays and five times more on Sundays. The study-oriented time allocation of Korean students resulted in less leisure time than the American students. Korean students spent their leisure time of more than 30 minutes participating in social activities, media, and hobbies, and their time allocation to volunteer work and religious activities were nil. On Sundays, the time for studying by Korean students was more than five times longer than that spending by their American counterparts. Koreans used their leisure time of 6 hours and 47 minutes mainly for media, hobbies and social activities. The participation rate of volunteering by Korean students was only 0.5%, though it was 31.0% for the Americans. For a study-life balance for Korean students, it was recommended that trends toward time management and social policy should increase the time allocation to sleeping, housework, work, sports, and volunteering and decrease the time use in studying and hobbies.

A study of facility securement and space utilization at national universities in Korea was conducted in order to help develop an efficient model for space management at national universities going forward. For the study, 36 national universities were asked to submit answers to a questionnaire on usage of campus facilities in 2013. We then analyzed the results of space management for the 27 universities that participated in the questionnaire in each of the past three years (2011-2013). Lastly, we conducted an awareness test on the space utilization policies and space management for these universities. The results are as follows. First, the aggregate average score for space utilization over the past three years is 74.06. The annual average score increased year-over-year and then decreased; it was 69.44 in 2011, 80.68 in 2012, and 72.05 in 2013. A decline in the sense of responsibility of universities to effectively manage space appears to be a factor in the decrease. Second, with 53% of respondents in agreement, treatment of campus area as private space appears to be the biggest hurdle for efficient space management. As such, a plan to foster a more communal view of campus facility area is required. Third, resistance from constituents to existing guidelines for space allocation on campuses appears to be limited (78.1% of respondents answered the guidelines currently in place were average, satisfactory, or very satisfactory). We believe this result points to a mutual understanding forming amongst constituents regarding guidelines on space allocation on campus.results of satisfaction research: the users are generally satisfied with education and student.

현재는 저출산 고령화 사회현상에 따라 한국의 교육환경이 급변하는 시점이다. 특히, 고등교육 시장에서 상당한 변화가 예상되는데 통계청의 보고에 따르면 2010년에서 2020까지 10년 동안 고등학생 수는 196만명에서 127만명으로 35% 감소하는 것으로 나타났다. 학생 수의 변화는 교원 수급문제와 직 간접적으로 연계되며, 이는 적정한 교육재정 배정 및 예산 확보와 함께 다시 학급 당 학생 수, 교사 1인당 주당 수업시수 등 교육의 양적 질적 부문에 매우 중요하게 영향을 미치게 된다. 이러한 상황에서 교육시스템 운용에 중요한 영향요인이며 결정요인으로 기능할 것으로 예상되는 재학 학생 수에 대한 정확한 예측모형의 제시는 향후 국가의 교육행정체제와 인사관리 방향성을 결정하는데 있어서 그 가치가 매우 높다고 사료된다. 이 연구에서는 시계열 분석기법의 특성 상 축적된 과거 데이터가 충분한 11개 시도의 고등학생 수 사례를 대상으로 한다. 주어진 실측 데이터에 대한 모형적합도 검정과 오차추정을 위해 다양한 시계열 예측모형과 오차 추정방식을 적용 하였다.

This study has attempted to investigate the time use of the elementary school students and their satisfaction levels by their general characteristics for the educational guidance. The sample of this study consisted of 387 elementary school students on Jeju Island who are in the fifth or sixth year. The data were analysed by frequency, percentage, mean, t-test, ANOVA and Duncan's test. The major results of this study were as follows; The results of this study showed that the students spent much time for studying including extra programs as like their ages. Also, their leisure time focused on watching TV or doing computer. The levels of satisfaction according to the time use were slightly high although their time allocation was not various. The time use of the students and their satisfaction levels were significantly affected by the general family situation related to parents as well as their own characteristics. The variables such as the student's sex, parent's educational level, whether the mother is employed or not, and monthly allowance were important to result in the differences of the time use and satisfaction levels among the students. The leisure time was strongly related with the satisfaction levels.

The current class scheduling has difficulties in reflecting students' preferences for the classes that they want to take and forecasting the demands of classes. Also, it is usually a repetitive and tedious work to allocate classes to limited time and cesourres Although many research studios in task allocation and meeting scheduling intend to solve similar problems, they have limitations to be directly applied to the class-scheduling problem. In this paper. a class scheduling system using multi agents-based negotiation is suggested. This system consists of student agents, professor agents and negotiation agents each agent arts in accordance with its respective human user's preference and performs the repetitive and tedious process instead of the user The suggested system utilizes negotiation cost concept to derive coalition in the agent's negotiation. The negotiation cost is derived from users' bidding prices on classes, where each biding price represents a user's preference on a selected class. The experiments were performed to verify the negotiation model in the scheduling system. The result of the experiment showed that it could produce a feasible scheduling solution minimizing the negotiation cost and reflecting the users' performance. The performance of the experiments was evaluated by a class success ratio.

Background: Some researchers state that they are not yet able to provide a deep understanding of the underlying causes of unsafe behaviors (UBs). Therefore, the present study was conducted to investigate the attitudes and experiences of Iranian workers of UBs. Methods: This present study was conducted in 35 industries using a semistructured interview based on grounded theory. Forty participants were interviewed, including 13 industrial safety and health experts and 27 workers and supervisors. The analysis of the present study consisted of a three-step coding process including open, axial, and selective coding. Results: The results showed that the factors affecting UBs could be classified into three categories: organizational, individual, and socioeconomic factors. Organizational factors were divided into 6 parts: procedure and environmental conditions, communications, monitoring, organizational safety culture, resource allocation, and human resources. Socioeconomic factors had three subcategories: community safety culture, type of organizational ownership, and economic problems. Finally, the individual factors were classified into two categories of personality traits and individual competence. Conclusion: The results showed that organizational factors were the most categorized, and it is estimated that this factor has a more important role in the UBs. Of course, to better understand the close relationship between these factors and find the weight and importance of each factor, it needs to measure it with multicriteria decision systems.
