Many restoration projects are underway to revive disturbed streams. In order to achieve successful stream restoration, a variety of microhabitats should be created to promote biological diversity. Research on biological classification of microhabitats is essential for biological diversity. However, research on classification using only physical environmental factors has been carried out. The purpose of this study is to classify and quantify the microhabitat of the stream by using macroinvertebrates systematically. In this study, eight wadeable streams and four non-wadeable streams were surveyed to identify the benthic macroinvertebrates in these various microhabitats. Among the physical environmental factors (current velocity, water depth, substrate), the particle size of the substrate was the most influential factor in the emergence of the Habitat Orientaion Groups. Among the HOGs, clinger and burrower were highly correlated with physical environment factors and showed the opposite tendency. The distribution of clinger and burrower according to the physical environmental factors showed two tendencies based on the current velocity (0.3 m/s) and water depth (0.4 m). In addition, the particle size of the substrate showed three trends (${\leq}-5.0$, -5.0 < mean diameter ${\leq}-2.0$, > -2.0). Based on the abundance tendency of these two HOGs, the microhabitats were classified into nine types, from a eupotamic microhabitat to a lentic microhabitat. Classification of the microhabitats using HOGs can be employed for creating microhabitats to promote biological diversity in future stream restoration plans.

This research aims to investigate the life-style and types of leisure experienced among airline flight attendants during temporary stays abroad. In this study 2 hypotheses based on literature reviews were employed. Questionnaires were also developed based on data collected from previous studies. Subjects of the study were focused on flight attendants in Legacy Airlines. Factor analysis and reliability coefficients were used to examine the internal consistency among variables. Seven dimensions of leisure, which are cultural experience, pursuit of success, social orientation, humanity, pursuit of fashion, shopping preferences and health-orientation were identified from factor analysis. Three dimensions of leisure, which include type of rest, type of sports, and activity of tourists, were identified from factor analysis accordingly. Lifestyle factors were extracted from a result of cluster analysis, cluster 1- Passive lifestyle, Active lifestyle community type 2, and Cluster 3 analyzed Self-satisfied lifestyle types. Airline cabin crew workers involved in the life style analysis can make good use of leisure time.

The goal of this study was to examine the effects of male gender role on the adjustment of Korean men. In study 1 Korean Male gender Role Scale was developed. A 52-item scale was constructed based on the responses of 432 college-aged and middle-aged men to theoretically-derived preliminary items. Five factors were extracted: achievement orientation, the initiative, task orientation, responsibility for family and friendship with male friends. Study 2 examined the relationship between male gender role and several adjustment variables. Correlational analyses indicated that in the college men self-esteem and career identity were positively correlated with the initiative and friendship with male friends was positively correlated with life satisfaction. College men's depression level was negatively correlated with the initiative and task orientation. Among the middle-aged men, self-esteem was also positively correlated with the initiative and task orientation. But responsibility for family was positively correlated with depression and job dissatisfaction in the middle-aged men. In both groups satisfaction with male gender role was positively correlated with self-esteem and life satisfaction but negatively correlated with depression. Finally, limitations of this study and direction of future research were discussed.

This study proposed a plan to seek a more practical way of life norm education of today's families on the basis of family rule in the traditional society by comparison between the older generation's family life rule education and college students. The study was made by analysing rules in Chosun Dynasty questionaire nair was drawn up on the basis of it. The subjects of this study were college students of one largest cities and their 800 parents. Collected data was processed by frequency analysis, ANOVA, interrelation and regression which are used through SPSS computer programs, Study results show that acceptance level is higher among the older generation but the necessity of family standare education is urgent beyond the generations. Also people who have lived with grand parents feel more necessity of education family norm. When the education could not be made in families because parents excessive protection examination-centered education, and bad effects of mass media then emphasis has to be made to create life culture which makes family norms to be kept continuously by the education at schools, education culture centers and public facilities.

Hrr25, a casein kinase $1{\delta}/{\varepsilon}$ homolog in budding yeast, is essential to set up mono-orientation of sister kinetochores during meiosis. Hrr25 kinase activity coordinates sister chromatid cohesion via cohesin phosphorylation. Here, we investigated the prophase role of Hrr25 using the auxin-inducible degron system and by ectopic expression of Hrr25 during yeast meiosis. Hrr25 mediates nuclear division in meiosis I but does not affect DNA replication. We also found that initiation of meiotic double-strand breaks as well as joint molecule formation were normal in HRR25-deficient cells. Thus, Hrr25 is essential for termination of meiotic division but not homologous recombination.

Participant observations, in-depth interviews, and analyses of documents were used for collecting data. Children separated from their parents were living with grandparents because their parents were working abroad. Results included socio-cultural and psycho-social factors. (1) The socio-cultural grounded factors or the common characteristics of young children's family life in both living circumstances included early childhood academic achievement orientation, demands of responsibility and obedience, limited opportunity for social development, and societal phenomenadeveloping wide family concept affected by China's Confucianism and Korean-Chinese social culture. (2) Psycho-social grounded factors included the present care-givers' perceptions of the child's agency and their beliefs in the importance of play and friendship. This affected interactions between child and care-giversand child's self-esteem and friendships.

The primary purpose of this study is to explore the daily lives of gay men and assess their interests in fashion and appearance management with the goal of better understanding the roles or meanings of fashion in their lives. In-depth interview method was adopted and the responses were analyzed qualitatively. Six homosexual men were interviewed, and the outcome of each conversation was recorded and analyzed; each man had a different background and thus showed different behavioral patterns. The life patterns distinct to Korean gays, the importance the highly patriarchal society places on family lineage and mandatory military service, for example, were discussed. Even though the interviewees asserted that their interests in fashion is not related to their sexual orientation, fashion was utilized as a means of self-expression by these gay men.

The purpose of this study was to investigate the variables that had an effect on the maturity of career attitude in middle school students. Independent variables were categorized into three groups: individual-related variables, family-related variables, and school-related variables. The individual-related variables were gender difference, academic year, academic achievement, and self-efficacy. The family-related variables were socio-economic status of the family, communication about career with parents, parental support, sibling's support, and value orientation of the family. The school-related variables included communication about career with friends, teacher's support, and friend's support. The subjects of this study were 490 students who were selected at random from first, second, and third grade of middle school in Daegu. A questionnaire was used for the survey. It consisted of a career attitude maturity scale, a self-efficacy scale, a communication scale, a value orientation of the family scale, and a social support scale. The data was analyzed by factor analysis, multiple regression analysis, and hierarchical regression analysis. The major findings of this study are summarized as follow: First, among the individual-related variables that had an effect on the maturity of career attitude in middle school students, self-efficacy affected all sub-factors of how mature they were in matters relating to career. Academic achievement affected decisiveness and preparation-- maturity of career attitude subfactors. And gender difference and academic year affected preparation and goal orientation. Second, the results of the family-related variables that had an effect on the maturity of career attitudes in middle school students were that communication about career with parents affected decisiveness, preparation, and confidence-- maturity of career attitude sub-factors, socio-economic status of the family and sibling's support affected confidence. And value orientation of the family affected goal orientation and independence. Third, the results of the school-related variables that had an effect on the maturity of career attitude in middle school students were that communication about career with friends affected preparation-- a maturity of career attitude sub-factor; teacher's support affected decisiveness, preparation, and confidence; and friend's support affected confidence and independence. Fourth, decisiveness, preparation, and confidence among the maturity of career attitude sub-factors were affected the most by individual variables. And self-efficacy was the most significant. Goal orientation and independence were affected the most by family-related variables.

Purpose: The purpose of this study was to describe feelings and actions of nurses following withdrawal of life-sustaining treatment from children being cared for by the nurses. Methods: Data were collected by in-depth interviews with 7 nurses from different hospitals where children receiving nursing care had life-sustaining treatment withdrawn. The interviews were conducted from August 2016 to February 2017 when all data were saturated. Interviews lasted 30~90 minutes and were conducted 2~3 times per participant. Data were analyzed using Giorgi's phenomenological research methodology. Results: The following factors constituted experiences of nurses working in pediatric wards when life-sustaining treatment was withdrawn from children: "agony and conflict in the aspects of care", "heavy mind and regret for exhausting care", "intentionally avoiding parents' sadness", "comforting sadness in the heart" and "orientation in the role of caring for children undergoing withdrawal of life-sustaining treatment." Conclusion: Findings indicate that support systems and intervention programs need to be developed so that nurses can understand and wisely deal with experiences of withdrawal of life-sustaining treatment from children who receive care from nurses.

The moss Physcomitrella patens has two life cycles, filamentous protonema and leafy gametophore. A modified from of suppression subtractive hybridization (SSH), mirror orientation selection (MOS), was applied to screen genes differentially expressed in the P. patens protonema. Using reverse Northern blot analysis, differentially expressed clones were identified. The identified genes were involved mainly in metal binding and detoxification. One of these genes was an AP2 (APETALA2) domain-containing protein (PpACP1), which was highly up-regulated in the protonema. Alignment with other AP2/EREBPs (Ethylene Responsive Element Binding Proteins) revealed significant sequence homology of the deduced amino acid sequence in the AP2/EREBP DNA binding domain. Northern analysis under various stress conditions showed that PpACP1 was induced by ethephon, cadmium, copper, ABA, IAA, and cold. In addition, it was highly expressed in suspension-cultured protonema. We suggest that PpACP1 is involved in responses to metals, and that suspension culture enhance the expression of genes responding to metals.
