Organic light-emitting materials in marine macrophytes from various coastal environments were identified. Twentyeight species from the solvent fractions were examined and identified as candidates for bioorganic light-emitting materials using photoluminescence (PL) spectra and gas chromatography-mass spectrometry. We selected 16 solvent fractions from a total of 1,221 prepared from Ishige okamurae, Sargassum confusum, Grateloupia elliptica, Chondracanthus intermedius, Porphyra yezoensis, Meristotheca papulosa, Gelidium amansii, and Scytosiphon lomentaria. The maximum light-emitting PL spectra appeared at various colors, mainly between blue and green, based on chromaticity coordinates, from solvent fractions of M. papulosa, G. amansii, G. elliptica, P. yezoensis, S. lomentaria, I. okamurae, and C. intermedius. These results will contribute to the development of novel organic light-emitting materials.

This study investigated the structural relationships between parental attitude, social support, self-esteem, and levels of adjustment to school life of children from multicultural families. Participants were 177 elementary school children from multicultural families in 1st to 6th grade of elementary school in the Daegu-Gyeongbuk area of South Korea. The major findings were as follows. 1) Parenting attitude, social support, and self-esteem had direct effects on levels of children's adjustment to school life. 2) Parental attitudes and social support had direct effects on children's levels of self-esteem. 3) Parental attitudes and social support also had indirect effects on levels of adjustment to school life of these children. This study suggested that various concern and supports from multi level of society are required to improve adjustment to school life in children from multicultural families.

A phenomenological methodology was used to identify the life of children living with alcoholic parents. Nine adolescents participated in the in-depth interviews, done between October and December 2001. The Colaizzi's method was used for data analysis. The results of this study are as follows. One theme and thirteen meanings were identified, The one theme is Paradoxical Coping in Life. The meanings are obsessive behavior as a way to control father's behavior, always on the defensive due to anxiety and tension, being afraid of life alone due to paranoid thoughts, contradictory expectations about father's drinking behavior due to life with chronic tension, stress becoming familiar and life being boring and tendious without stimulation, life that is fake and filled with misinterpretations about reality, affection sought from others due to loneliness, compensatory life within peer group, negative expectation about the future due to negative experiences, controling others to protect ego, denial of real emotion to protect self from hurt, life of regretting self, and strong need for approval from others. The results of this study can provide a foundation for the development of programs for children of alcohol dependent parents.

The purpose of this study is to understand a migrant women's married life. The study examined migrant Filipino women's married lives, motives for marriage and migration to Korea, and their married life experiences. The results showed that these women get married to Korean men in pursuit of an economically better life to support their family in the Philippines through marriage migration. As for Filipino women's perceived difficulties in married life, they indicated hardships with redrawing the boundaries of nationality, as well as their husbands' faults or bad habits which are different from what they expected before marriage. Other difficulties mentioned were the peculiar culture of living with parents-in-law, and general difficulties in married life. This study showed that marriage migration results not from external pressure or motives but ultimately from their own decision in a social and cultural context. It was also implicated that Korea's superior position to the Philippines in international economic power has an effect on family relations. The boundaries of nationality are redrawn according to their married life. In addition, it was revealed that the Korean born children of migrant mothers who divorce because of difficulties in married life are in a very poor situation as their national identity depends on their mother's future marriage relations.

The purpose of this study is to investigate the relationship between work-family conflict and job-life satisfaction of married female workers. Two data sets were used in this study. Both data sets were gathered from structured questionnaires and time dairies. The first data set was collected from 370 married female production workers in 1995 and the second set was collected from 143 married female clerical workers in 1996. Job and life satisfaction were measured on 5-point Likert scale where 5= very unsatisfied and 5= very satisfied. The overact means for both groups were 2.97, 3.09 for job and life satisfaction respectively The findings of this study are; 1) Clerical workers have significantely higher job and life satisfaction than production workers. 2) Multivariate analysis reveal that work-family conflict is negatively related to job satisfaction while income is positively related to job satisfaction. 3) In the path analysis model, work-family conflict has a negative direct effect and indirect negative effect mediated through job satisfaction on life satisfaction. Job satisfaction and husband's division of housework have a positive direct effect on life satisfaction. However, total labor time has a negative indirect effect mediated through work-family conflict on life satisfaction and income huts a positive indirect effect mediated through job satisfaction on life satisfaction.

Purpose: The study examined factors related to the meaning in life in elderly in one city. Methods: The sample consisted of 217 subjects all of which were over 60 years of age and were recruited from two community senior centers from December 2008 to February 2009. Data collection instruments were the Meaning in Life Scale, Social Support Index, CES-D, and RULS questionnaire. SPSS/WIN 17.0 was used for descriptive analysis, independent t-test, one-way ANOVA, and correlation coefficient. Results: The mean of the score from the Meaning in Life was 50.04 (range 10~70). There were significant differences in subjects' perception of meaning in life according to age, level of education, religion, having a spouse, satisfaction with relationship with children, and frequency of visits to a community senior center. Meaning in life was significantly correlated with family support, depression, and loneliness, which were significant predictors (21.5%) of meaning in life. Conclusion: To improve meaning in life of the elderly who visited a community senior center, nurses may pay attention to depression, loneliness, and family support.

Purpose: The purpose of this study was to examine the relationships among perceived health, parental stress, social support, and quality of life of grandparent caregivers and to identify the factors influencing quality of their life. Methods: A descriptive correlational design was used. The data were collected by questionnaires from a convenience sample of 130 participants taking care of their grandchildren from ten children's daycare centers in Seoul, Korea from August to September, 2013. Data were analyzed using t-test, ANOVA, Pearson's correlation efficients, and multiple regressions. Results: Perceived health, parental stress and social support were correlated significantly with quality of life. As a result of the multiple regression analysis, education level, age of grandchildren, perceived health, parental stress and social support accounted for 48% of the variance in quality of life. Perceived health, parental stress, and social support were identified as factors influencing quality of life and the variable that most affected quality of life was perceived health. Conclusion: The results of the study indicate that health of people taking care of their grandchildren must be promoted while relieving their parental stress with appropriate social support in order to improve quality of life.

Purpose: The purpose of this study was to explore and understand life and meaning in life of elementary school students. Methods: Data from 1,790 higher grade elementary school students were analyzed for content of meaning in life. Results: The students described the following: 1) Meanings of living existence included, 'living things', 'importance', 'human life', 'family', 'event', 'eternity', 'origin of life', 'disease', and, 'protection'. 2) Four categories were found for reasons why human life is important, 'solitary', 'limitation', 'valuables', and 'living'. 3) Things that one can do to protect the value of human life were, 'doing safely', 'keep things well', 'altruistic behavior', 'doing sound activity', 'preservation & development', and 'devotion of oneself'. 4) Meaning of life included 'to accomplish plans', and 'to do things' 5) Cases when students felt life had meaning were 'perform meaningful behavior', 'comfortable emotionally', and 'receiving help from others'. 6) The methods by which to live a meaningful life were 'working diligently', 'serving', and 'doing rightly'. Conclusion: These results suggest that students recognize the meaning of life in a most positive way and with a relatively wide scope, but as a few students had a negative orientation, age-appropriate and more systematic education programs are needed.

The purpose of this study was to analyze the space of upper class housing in Andong through the oral life history of women in terms of sexual life. Even though the living was centered on women, the women of Joseon were alienated from the history. For this reason, the life history of head family housing was not recorded in the language of women, and often passed on orally. Also sexual life is a important part in daily life, but it is hard to be recorded or mentioned in Confucian society, and there is not much space research related to sexual life. Now there is not a lot of head family housing left, and the number of people who can tell the life history which is not recorded and the storyteller is also decreasing. From now on, I will record what I have experienced or passed through interviews of the residents living in head family housing and then analyze the characteristics of the sexual life.
