Studies on time-use have generally concentrated on the amount of time used by each member of a household in Korea. The quality of family relationships could be associated with the amount and types of interactions between family members. This study examined the time that adults spend with their family members on various activities. The purpose of this study is to explore a typology of family time and investigate the characteristics of each type. The data source was the 2009 Time-Use Survey conducted by the Korean National Statistics Office. The people involved in each activity were surveyed for the first time in the 2009 survey in Korea. The data from this study included 10,902 diaries that were filled on weekdays by married adults from ages 20 to 59 years. Data from rural households were excluded. Time use was divided into three categories: family meals, household work and family leisure time. These activities were analyzed using t-test, chi-square analysis and cluster analysis. Family time was classified into four types based on three categories. The four types were named "leisure sharing", "household work sharing", "overall sharing" and "non-sharing". The most common type was non-sharing. The characteristics of each type depended on gender and paid work time. Based on these results, family and labor policies should be developed to increase the work-life balance. Policies that focus on men over 40 years are especially recommended.

Learning analytics, or educational data mining, is an emerging field that applies data mining methods and tools for the exploitation of data coming from educational environments. Learning management systems, like Moodle, offer large amounts of data concerning students' activity, performance, behavior, and interaction with their peers and their tutors. The analysis of these data can be elaborated to make decisions that will assist stakeholders (students, faculty, and administration) to elevate the learning process in higher education. In this work, the power of Excel is exploited to analyze data in Moodle, utilizing an e-learning course developed for enhancing the information computer technology skills of school teachers in primary and secondary education in Greece. Moodle log files are appropriately manipulated in order to trace daily and weekly activity of the learners concerning distribution of access to resources, forum participation, and quizzes and assignments submission. Learners' activity was visualized for every hour of the day and for every day of the week. The visualization of access to every activity or resource during the course is also obtained. In this fashion teachers can schedule online synchronous lectures or discussions more effectively in order to maximize the learners' participation. Results depict the interest of learners for each structural component, their dedication to the course, their participation in the fora, and how it affects the submission of quizzes and assignments. Instructional designers may take advice and redesign the course according to the popularity of the educational material and learners' dedication. Moreover, the final grade of the learners is predicted according to their previous grades using multiple linear regression and sensitivity analysis. These outcomes can be suitably exploited in order for instructors to improve the design of their courses, faculty to alter their educational methodology, and administration to make decisions that will improve the educational services provided.

몽골의 초원이나 사막과 같은 개방지역에 설치된 송전선로에서 발생하는 조류 감전사고는 매우 흔하게 보고되고 있다. 본 연구는 조류피해조사를 위해 2017년 몽골 남부지역의 준사막 지역에 설치된 15-kV의 송전선로에 4월, 7월, 9월 등 총 3회에 걸쳐 조사를 실시하였다. 전체 250개의 전신주 구간에서 총 12종 45개체의 감전사한 조류를 확인하였다(10㎞마다 1.12% 사망률). 주요 감전 피해 조류는 멸종위기종인 Falco cherrug (n=11)와 Milvus migrans (n=11)로 나타났다. 본 연구지역과 같이 개방된 환경에서의 조류를 위한 잠자리 또는 휴식처의 부족은 보다 많은 조류의 감전사고를 발생시킬 수 있으며, 특히 몽골의 다른 개방지역에서도 발생할 수 있다. 사고현장에서 종동정이 어려운 개체의 경우, 시료의 유전자 증폭 등을 통해 DNA 분석을 실시하여 동정하였다. 본 연구결과 몽골의 개방지역에서 조류의 감전사고는 조류에게 발생하는 위험요소 중 높은 비율을 차지하고 있는 것으로 확인되었으며, 특히 맹금류에게 빈번하며, 간헐적으로 이동철새에게도 일어나고 있는 것으로 확인되었다. 개방된 지역일 경우 조류의 감전사고가 더 잘 발생할 수 있으며, 감전사고와 같은 조류의 위험요소를 보다 잘 이해하는 것은 멸종위기종과 같은 종보전에 기여할 수 있을 것으로 판단된다.

The purpose of this study is to determine what factors affect the marital life of multicultural families. In-depth interviews were conducted with 15 immigrated females and their husbands living in Yongsan-Gu, Seoul, Korea, by open-ended questionnaire. The interviews took place on September 11, 2008, and October 11, 2008. The major findings can be summarized as follows: Through the content analysis of the informants' responses, three major factors were found to influence the successful adjustment of the married female immigrants: personal factors, familial support, and social support systems. Among the personal factors, the self-esteem of the married couples is relatively high. However, the factor of the economic living conditions of the multicultural families indicates some difficulty. Finally, considering the level of self-development of the female immigrants' husbands, an older husband was viewed more negatively than a younger one. In terms of familial support, the most important factor affecting the adjustment of a foreign wife is the trust of her husband and her relationship with the husband's family. Accordingly, educational programs are necessary to promote multicultural understanding and the couples' relations. In social support systems, the female immigrants experienced neglect, as far as multicultural prejudice in society. Therefore, in order to revitalize the self-esteem of immigrants, we need to reach out to multicultural families. The center for support of multicultural families provides opportunities to find training, upgrade education for employment, and expand their social network. In addition, it is necessary for the national public relations industry to recognize improvements regarding the adjustment of multicultural families.

The purpose of this study is to examine the allocation of time between work and leisure by the rural elderly in Korea. The data used for this study are collected from fm households during the peak ($17^{th}\;to\;30^{th}$ June) and off-peak ($28^{th}$ November to $10^{th}$ December) farming seasons of 2005 using time diary. The sample for this study consists of 120 elderly over 65 years old living in rural area in eight provinces. The major findings are as follows. (1) The time spent of farm work by rural elderly in much longer than average work hours of elderly in general regardless of farming season. The indicates that the elderly farmers are the sustaining forces of agriculture as the urban industrial sector absorbs the younger labor force rural area. (2) There are significant differences in the work time(including form work, housework, and farm work plus house work) by gender, age, education, marital status, living arrangements. (3) The rural elderly spends less time in leisure compared to the elderly in general even during the off-peak season. (4) Especially during the peak season, time allocation between work and leisure by the rural elderly is heavily skewed, resulting in an inadequate amount of time for reproduction of labor. (5) There is only significant age difference in the amount leisure time regardless of farming season. (6) Male elderly farmers work approximately 30 minutes to 1 hour longer on farm than the females do, but the total work time (farm work plus housework) of female elderly is longer than that of the male elderly. There is no significant gender difference in the amount of leisure time during the peak season, whereas the men have more leisure than the women during the off-peak season. To conclude, the gender differences in time allocation among the rural elderly are minimal. However, the rural elderly of both genders suffers from excessive work hours and heavy workload compared to the urban counterpart.
