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.

Social capital is an important resource for Korean immigrant children's successful school life in the U.S. because most immigrants are not familiar to new language and culture. However, immigrant parents and their children have limited ability to join and create social networks freely both inside and outside school. We, the researchers of this study, adopted qualitative research method: open-ended in-depth interview, coding and analysis based on grounded theory. The result of this study reveals that Korean immigrant parents utilize their coethnic networks in getting educational information and English plays important role in educational decision-making process of the parents.

With the recent spread of the concept of Smart Cities which is to solve urban problems with ICT technology, Living Lab, which identifies the demands of citizens who dwell in the city and verifies the acceptability of the services being introduced, has become an important topic. Living Lab is an open innovation platform introduced in consideration of the user's perspective in real life and is a new approach in that service developers use collective intelligence in the process of Co-creation with users. Living Lab is operated on topics which is close to citizens' daily lives such as energy, housing, transportation, and education. In particular, as energy and environmental-focused Living Lab emerges in accordance with the 'Korean New Deal Policy', interest and importance in the field are increasing. The paper derives the characteristics of water resource Living Lab through case analysis of several Living Lab practices. Water resource Living Lab in Daejeon and Chuncheon, which are located in Korea, and water resource Living Lab in Romania and Indonesia are covered in this paper as the reference. The paper finally analyzes the case of Sambang Water Living Lab in Gimhae, which is the city located in southern part of Korea. As a result of case analysis, the urban water resource Living Lab focuses on the raw water of urban water resource and should respond sensitively to the safety of citizens. And for the success of this urban water resource Living Lab, it is essential to ensure that citizens participating in the Living Lab clearly understand the concept of water resources, and citizens' opinions to be implemented as services.

Bird electrocution on contact with electricity lines is well reported and is quite common in Mongolian open areas. We visited 15-kV electricity distribution pole lines in a Southern Mongolian semi-desert region three times in 2017, in April, July, and September, to assess their risks to birds. The carcasses of 45 electrocuted birds representing 12 species were identified from 250 poles (overall mortality rate of 1.12% every 10 km). The majority of these electrocuted birds were endangered Saker Falcon (n=11) and common Black Kite (n=11). The lacks of roosting or perching sites in our study sites (indeed other open areas in Mongolia) may resulted for such high rate bird electrocution. A 751-base pair (bp) cytochrome c oxidase I (COI) gene was amplified for DNA sequence-based identification of carcasses that were difficult to identify directly. Our findings revealed the high electrocution risk for birds in Mongolian open areas, especially for the birds of prey, with relatively low-efficiency electrocution mitigation approaches. The findings also indicate that there is a need for better understanding of the risk of bird electrocution, particularly in the open areas. This will contribute to the conservation of endangered species.

The purpose of this study was to figure out married female immigrants' experience and process of investing in human capital in Korea. The participants were 11 women from multicultural families who had experience of investing in human capital in Korea, could communicate in the Korean language, and were living in Daegu. The data were collected using intensive interviews. The major findings were as follows: The participants' level of education and work experience in native country were not accepted as human capital and offered no advantages or obtaining employment in Korea, while English language skills were useful for those pursuing an English lecturer position. The motives for investing in human capital were 'adjusting to early stage of marriage and a new environments', 'for their childrens' education', 'to improve female immigrants' level of education', 'seeking a better job', and 'advocating more education'. The types of investing in human capital were 'learning Korean language and culture', 'applying to Open University or taking a middle or high school qualification examination', 'obtaining certification', and 'entering regular university'. The participants' plans for investing in the future were 'finding their own job', 'entering regular university', and 'participating in useful educational programs including Korean language skills for daily life' The results showed that the participants' motives for investing in human capital were related in the stage of their marriage. The phases and changes in their motives during a marriage proved that the participants continued to invest in human capital according to their needs and situation.

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 analyze the family's meals of the daily time use and to examine how shared meals time together with family is influenced by socio-demographic variables. The Time Use Survey data collected by Korean National Statistical Office in 2009 is used. Among the total sample of 21,000 individuals, 9,179 samples who are married, aged from 20 to 59 years old and non-farmers are selected for analysis. The statistical methods are frequency, percentage, and censored regression model. The following is a summary of the major findings. The first, compared with the research results in 1999 and 2004, the time use of meals by adults is longer. But average time of family meals decreases and rates of family meals participants 2009 decrease 5.6% than 1999. Secondly, the family meals time increases from about 36 minutes on weekdays to about an hours at weekends. Regardless of the day, the women's family meals time is longer than that of men's. Thirdly, the influencing factors on family meals are sex, age, education, presence or absence of spouses, monthly income, weekly working hours and presence or absence of preschoolers. And the magnitude of gender differences in daily shared meals is not particularly large except in the case of some socio-demographic variables. Regardless of the day, women's family meals time is more affected by either dual-earner status or monthly income than that of men's.

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.
