The total number of taxa was 1,990 consisting 167 families, 770 genera, 1,818 species, 121 varieties and 50 forma. Three families, 4 genera 4 species and 1 variety in Pteridophyta and 1 family, 1 genus I species, 1 forma of Coniferophyta were endemic to Jeju. Five families, 8 genera and 8 species in the Monocotyledonae of Endospermae and 23 families, 32 genera, 21 species, 16 varieties and 7 forma and 44 taxa in Cholipetalae, and 9 families, 24 genera, 12 species, 13 varieties and 7 forma, total 32 taxa in Sympetalae were endemic to Jeju. Total 90 taxa with 41 families, 69 genera, 46 species, 29 varieties and 15 forma were drawn up as endemic plants in Jeju. As the numbers show on, Jeju has more biodiversity especially plant diversity than any other places in Korea. It was an important region in regard to geographical position. The rarity on plants from Jeju has been assessed based on the IUCN red list categories and criteria at both regional and global levels. There was one species in each extinct (EX) and extinct in the Wild (EW). The EX and EW species were Rhododendron saisiuense Nakai (Ericaceae) and Asplenium antiquum Makino (Aspleniaceae), respectively. Three taxa, Rhododendron dauricum L. (Ericaceae), Lycopodium sieboldii Miq., and Lycopodiella cernua (L.) Serm (Lycopodiaceae) were species that is extinct in the region (RE). Sixty-one taxa were critically endangered (CR), 13 were endangered (EN), and 83 were vulnerable (VU) at regional level. The taxa listed on a Red List corresponds 26.9% of total taxa in Jeju. At global level, there were 19 taxa in CR, 4 in EN, and 1 in VU (Vulnerable) as the category of threat. The rest taxa (133 taxa) were classified as Least Concern (LC). According to the results of the assessment, conservation measures must be taken for total of 157 species that were categorized in threaten including one of EX, one of EW and three extinct in the region immediately.

The purpose of this study is to explore the structural relationships among parents' educational involvement and parental efficacy on students' school life satisfaction and school achievement and to determine whether there are any differences depending on family type and school level. Using data from 2,497 families that participated in the 2018 National Survey on Children's Life, t-tests and structural equation modeling were conducted. The results of this study demonstrated that two-parent families reported higher levels of educational involvement than single-parent families and custodial grandparent families. Also, two-parent families raising children in elementary schools showed higher educational involvement than two-parent families raising children attending middle schools. Second, parental efficacy was found to mediate the effects of parents' educational involvement on students' school life satisfaction and school achievement. Third, the path coefficients between parents' educational involvement, students' school life satisfaction, and school achievement showed statistically significant differences depending on family type, with two-parent families having greater involvement than single-parent families and custodial grandparent families. Fourth, multiple group analysis reported a statistically significant difference in the relationship between parents' educational involvement and school achievement as well as parental efficacy and school achievement depending on the school level.

Material hardship measures have been used to supplement the traditional income-based poverty measures. Recently poverty researchers have increasingly used measure of material hardship to examine the well-being of low income families. Measuring the material hardship might be useful to a better understanding of the multi-dimensions of the poverty in Korea. Using the data of the Korea Welfare Panel Study(the fourth wave), I examine incidences of material hardship across quintiles of the income distributions and the factors that might affect the experience of material hardship among the poor families. Major findings are as follows. Descriptive results show that nearly one-fifth of all families had experienced at least one of the five material hardships in the year. Those in the bottom quintiles and the poor families are more likely to experience material hardship than the other quintiles and non-poor families. But, incidences of the material hardship in the middle income quintiles and low income families are not a few(18 percent and 37 percent). Logistic regression results show that family-consumption related variables, income other economic resources(asset and public assistance), and household's employment status affect the experience of material hardship among the poor families. But, material hardship among the poor families is not significantly related with family income. These results indicate that material hardship measures are the useful indicators to understanding the multi-dimensions of the poverty in Korea. And they suggest that an extensive reform of the public assistance policy is necessary to relieve the material hardships of the poor in Korea.

The purpose of this study was to investigate the changes of lives and problems of 'Kirogi'(or Wild Goose) fathers, who were called fathers in the 'Kirogi' families, South Korean families separated by an ocean. They almost sent too much money that were $50-100\%$ of their family income to the families abroad, and got economic pressures so severely. More or less, they sold their own real estates, moved to much smaller sized house. and often expended the saving money. Also, they had difficulties of taking care of their children and felt lonely very much. By the hand, they might experience the adaptation process through 3 stages-troubles, acception(or wandering or enjoy), adjust (or violation). They had three types of problems, that is, family relationship problem(the isolation), psychological problem(loneliness and self-control), economic problem (financial pressure and drop of economic status). They found the strategies to overcome these problems for themselves. Firstly, they took lots of methods like email, internet chatting, phone, etc. to communicate with their family everyday and made many events to strengthen the ties among families. Secondly, they got rid of stresses mainly by joining with their colleagues at work. Finally, they decided to lower the standard of living of their family in foreign country or tried to find their wives' jobs to prevent the financial hardship.

Since the Framework Act on Healthy Families came into effect in 2005, family policy has become a primary field of social policy, and 'family' has emerged as an important keyword for solving Korean society's various phenomena and problems. In order to seek practical plans for reforming social policy through family policy, this thesis has analyzed the transitional characteristics of Korean families in relation to where Korean families currently stand and the situation they are facing. This thesis has also reviewed the content of family policy in the master plan of healthy families, the starting point of the actual family policy, and other related policies. It also has analyzed the key content of child care support policy. From these various analyses and discussions, this thesis has emphasized "family care" as the keyword of family policy, family effect analysis as the means of reinforcing family perspective, and family integrity for policy effectiveness.

This study aims to examine experiences of adoptive families, mainly focusing on mothers with their biological children and adopted a child, through a phenomenological approach. The subjects of this study are adoptive family's mothers with their biological children according to a criterion-based selection. 15 mothers who adopted children under 12 months, who are currently aged over 6, are selected and given personal and in-depth interviews, questions ranging from the process before adoption, foster care and changes in family relationships to the issues caused by adoption and coping methods. 6 steps of a phenomenological method that Colaizzi(1978) proposed are applied to analyze the data. The results of this study are as follows. The central theme of this study is 'A family which has harmonized with love beyond blood ties'. First, the participants have shown difficulties in different aspects over adoption than those of sterile families. The motive of their adoption is to let adopted children experience a happy childhood in a loving family. Secondly, the participants have adjusted themselves to new adoptive families, have committed to the care of their new children, and have experienced a change in family relationships. Finally, adoptive families have successfully been settled while overcoming difficulties together.

The purpose of this study was to explore the perceptions of preservice teachers toward children from single parent families. 218 preservice teachers (209 female and 9 male) who were enrolled in the department of early childhood education and child care & education were participated in this study. A questionnaire was developed based on the questionnaire developed by Song, Sung, & Han (2003). Data were analyzed by using SPSS 11.5. The results were followed. First, preservice teachers' personal experiences of single parent families did not influence their perception of children from single-parent family. Second, preservice teachers who strongly held the view of keeping traditional family structure showed negative expectations of children's school adjustment. Third, preservice teachers reported the importance to help the children adjustment at school as well as to deal with their personal and family problem. The results presented that there was an increasing need in teacher education, to develop curriculum for preservice teachers to have balanced views or reduce their biased perception against diverse family structure and children from single parent families.

Purpose: This study was designed to develop and test a structural model for children's adaptation in divorced families. The hypothetical model was constructed based on the Family Resilience Model by McCubbin and McCubbin. Methods: Data were collected using self-report questionnaires from 219 children (3-6th grade) in divorced families. The children attended one of 22 community agencies, 8 after-school programs, 3 elementary schools in three cities in South Korea. The collected data were analyzed using LISREL program to test the hypothetical model. Results: The modified model was constructed by deleting four paths in accordance with the statistical and theoretical criteria. Compared to the hypothetical model, the revised one had a better fit to the data. Self-esteem, and beliefs about parental divorce had direct effects, and family communication and internal control had indirect effects on children's adaptation in divorced families. These variables explained 56% of the variance in children's adaptation. Conclusion: The modified model was supported by empirical data. This model could be applied to family nursing interventions with divorced families or any other suffering family transition. When working with children experiencing parental divorce, it is important for nurses to enhance children's self-esteem, family communication and to decrease children's negative beliefs about parental divorce to help in their adaptation.

Korean families have been undergone tremendous changes during the past three decades with societal changes. Korean families become smaller, diverse, and multi-cultural. These family changes challenge child development research. Family is not just an intimate relationship. Family is also a structural environment, a system linking micro and macro system, an institution, and an ideology. Consequently, researchers need to pay attention to various ways family influence child development and take into account family as a whole unit. Researchers are also challenged to make a stance regarding family changes and diversity. Temporality is another important issue in studying how family development and child development interact. In terms of public policy, social services should be developed to cope with the new social risks from family changes and to mitigate a growing developmental gap among the children of families with different economic classes.
