In the context of dramatic change in the formation of the Korean family, this study attempts to examine the role of social safety net in family disruption. This study selected 366 individuals who experienced family disruption, mainly divorce and separation, using the 1996 Panel of Survey of Income and Program Participation (SIPP). Methodologically, due to the absence of proper longitudinal data in korea for the purpose of this study, the study analyzed the SIPP and attempted to provide policy implications for Korea. Findings of the current study confirmed that women with children experienced severe economic decline upon family disruption. American social safety net was insufficient to protect mother with children from poverty. Findings imply that Korea needs to develop public policies to protect mother-only-families, who experienced family disruption, from poverty. Expanding and reforming the eligibility of public assistance can be an important policy recommendation. A strong guideline for awarding child support, an active labor market policy, and EITC may have a positive effect on increasing the income of mother-only-families.

Compulsive consumption is regarded as a global phenomenon that can adversely affect consumer well-being. Although the topic has been studied in different cultural settings, we have seen relatively little theory development and explanations of compulsive behavior Nearly all previous empirical studies attempt to explain this behavior by correlating measures of compulsive behavior with independent variables taken within the same time frame. However, recent developments in social sciences suggest that such a phenomenon may best understood in the context of the person's earlier-in-life experiences. Using the life course paradigm as an overarching framework, the present research extends previous work on this topic. Following hypotheses were drawn from literature review: H1: The earlier in childhood and adolescence a person experiences family dislocation, the greater his or her likelihood of exhibiting compulsive behaviors in adulthood. H2: The earlier in life the young person experienced family dislocation, the greater the number of family disruption events the young person experienced prior entering adulthood years. H3: Family dislocation leads to (a) increased frequency of socio.oriented family communications and (b) decreased frequency of concept-oriented family communication. H4: Young adults who were raised in families characterized by a strong socio-oriented communication structure are more likely to exhibit compulsive consumption tendencies than those who were raised in families characterized by a weak socio-oriented family communication structure. H5: Young adults who were raised in families characterized by a strong concept-oriented communication structure are less likely to exhibit compulsive consumption tendencies than those who were raised in families characterized by a week concept-oriented family communication structure. H6: The relationship between family disruption events experienced during adolescence and perceived stressfulness of these events is moderated by (a) global family support, (b) emotional family support, and (c) material family support. Those reporting higher levels of family support as teenagers are less likely to report experiencing stress due to family disruption events. H7: Perceived stressfulness of family disruption events experienced during adolescent years are associated with compulsive consumption tendencies in early adulthood. H8: The greater the number of family disruption events young adults experienced during their adolescent years the more frequent was their communication about consumption with their peers. H9: The more frequent was the young persons' communication with their peers about consumption during their adolescent years, the more likely they are to report compulsive buying tendencies as young adults. We use a sample of 120 Thai undergraduate students attending classes taught in English as part of a four-year international program. Product-moment correlations, hierarchical regression analysis and partial correlation were used to analyze data. Results of testing hypotheses showed that hypothesis 2, 4, 7 and 9 were supported and hypothesis 1, 3, 5, 6 and 8 were not supported. Our study did not find a significant relationship between the age when a person experienced family dislocation and their compulsive behavior tendencies expressed as young adults. We did not find a significant relationship between family dislocation and family communication structures. But we found a significant positive relationship between socio-oriented communication structure and compulsive buying and a significant relationship between our peer communication and compulsive buying measures. Also we found perceived stressfulness due to the disruptive events to have a significant positive relationship between the perceived stressfulness and compulsive buying. Implications from these findings, limitations of this research and future research suggestions were discussed.

This study investigated the moderating effect of negative emotionality on the association between teacher-child intimacy and peer interaction based on a differential susceptibility model. The participants were 252 three-year-old children recruited from a day care center and preschool located in Incheon and Gyeonggi province. The teacher-child relationship was measured on a Student-Teacher Relationship Scale. This measure is a type of teacher's report with ratings based on a teacher's daily observations. This scale is composed of closeness items on the degree of warmth and open communication in teacher-child relationships. Peer interactions were measured with a Penn Interactive Peer Play Scale. This measure is composed of play interaction items, play disruption items and play disconnection. Negative emotionality was measured with Child Behavior Questionnaire. Teachers measured teacher-child intimacy and peer interaction scales. Parents reported children's negative emotionality. The research showed that negative emotionality moderated the association of teacher-child intimacy, play interaction, play isolation and play disruption. The magnitude of association between teacher-child intimacy and play disconnection as well as play interaction was greater for high levels of negative emotionality. Teacher-child intimacy was significantly associated with play disruption only for high levels of negative emotionality. The findings of this study support a differential susceptibility model.

Background: Cancer is a major life event that imposes huge economic and mental burdens on patients and families. In addition, the diagnosis of cancer also causes significant family discordance that can lead to marital problems such as divorce or separation. The aim of this study was to investigate the association and any related gender differences between cancer diagnosis and marital disruption among cancer survivors. Materials and Methods: We used the recent cross-sectional Korea National Health and Nutrition Examination Survey ($4^{th}$ and $5^{th}$; Years 2008-2012). The study participants were 623 married cancer survivors over the age of 19. A multivariate logistic regression analysis was conducted to estimate odds ratios. Results: After adjusting for socioeconomic status and health-related behaviors, the odds ratio of marital disruption among female cancer survivors compared with male cancer survivors was 3.94 (95%CI 1.30-11.94; p=0.02). The odds ratio of marital disruption for the below-average economic level compared with the above-average economic level was 5.64 (95%CI: 1.03-31.02; p=0.05). When compared with the non-smoking cancer survivors, the smoking cancer survivors had an OR of marital disruption equal to 2.94 (95%CI: 1.08-8.00; p=0.03). Conclusions: The findings of this study suggest that the odds of marital disruption among female cancer survivors are higher than those among their male couterparts. Medical practitioners should be sensitive to early signs of marital discord in couples affected by a cancer diagnosis. Early identification and psychosocial intervention might reduce the frequency of divorce and separation and thus improve quality of life and quality of care for cancer survivors.

The purpose of this study is to investigate the influence of children's socia-demographic variables(i.e., gender, birth order, and the amount of time staying in kindergarten) on, leadership, self-regulation and children's peer play behaviors. The participants of this study are 336 children aged between five and seven in four classes in a private kindergarten and eight classes in a private preschool located in the capital region. The results revealed that, girls showed more leadership, self-regulation, and play interaction section than boys: whereas, boys showed higher response in play disruption and the lack of play disconnection. However, birth order, did not have a significant effect on the sub-domain of leadership, self-regulation competence, and peer play behaviors. As for the duration children stay in preschool or in preschool or kindergarten, children who spend half-day showed higher reaction in behavioral self-control and emotional taking abilities than children who stay in the preschool or kindergarten full day. On the other hand, self-esteem of full-time children was higher than half-time children. Children who were emotionally sensitive, knew how to lead their peer group, and those who were sociable and self-regulated presented to be more active in peer-interaction than others. Second, as the result of the correlation analysis reveals, children's leadership, self-regulation competence, peer play behaviors, and play interaction had a meaningful effect on the sub-variations of children's leadership and self-regulation and they showed significant influence upon play disruption and play disconnection. In addition, girls who were not able to manage or to inspect their behavior and had insensitive emotion demonstrated higher tendency to play disconnected. Children, who participated in full-day program with having difficulties in self-regulation or inspecting their behavior properly but had a strong leadership and insensitive showed play disruption highly.

The caregiving experiences of 100 family menbers of outpatients with schizophrenia and schizoaffective disorders were investigated for the presence of positive(positive family-patient relationship. patient' contribution to the family) and negative caregiving experience(objective and subjective burden) and their predictors. This study attempts to make the analysis of caregiving experience more useful by expanding the focus to incoporate these positive aspects of the experience of family caregiver. Objective burden consists of two elements: 'disruption of family life', 'care'(amount of caregiving related to activity of daily living). Subjective burden is defined as emotional reactions to the care giving and it comprised of 6 emotional subdimensions such as 'stigma', 'grief'. 'worry', 'pity', 'fear', 'despair'. Also we investigate the severity of patients' disturbing behaviors into two categories, positive and negative disturbing behaviors and patient' contribution to the family as a predictors of positive and negative caregiving experiences. This study use Pearson's correlation coefficient, Hierardhical regressions in the SAS Program. The results are as follows: 1. Respondents reported moderate level of objective burden 'disruption of family life' (mean = 2.48, range = 1-4), and 'care' (mean=2.54, range = 1-4), and slightly high level of total subjective burden(mean = 2.19, range = 1-4). Mean scores for the measure of the severity of behavioral disturbance indicated that the caregiver experienced negative disturbing behaviors around almost 'somtimes'(mean=2.28, range = 1-4), and positive disturbing behaviors 'almost not frequent'(mean=2.78. range=1-4). So they reported that they perceived patient's negative disturbing behaviors more than positive disturbing behaviors. Mean scores for the measure of the patient' contributions (mean = 1.99. range = 1-4) indicated that caregivers experienced these contributions a little. It means that there should be a positive aspect of possibilities of patient' family roles that can be developed in the daily life. Mean scores for the measure of the positive family-patient relationship indicated that caregivers experienced moderate level of positive family-patient relationship(mean=2.52, range = 1-4). 2. Hierardhical regression analysis 1) Hierardhical regression of 'disruption of family life' showed that the interaction between positive disturbing behaviors and patient' contributions (B = .20. p = .022) and caregiver's educational level(B=.06. p=.000) were 'significant and Hierardhical regression of 'care' showed that 'negative disturbing behaviors'(B= .35. p= .007). 'patient' contributions'(B= .28, p= .019). 'family income'(B=-.l1. p=.096) were significant. 2) Hierardhical regression of 'total subjective burden', 'stigma', 'grief', 'worry', 'pity'. 'fear', 'dispair' showed that 'positive disturbing behaviors'(B=.51. p=.000). 'negative disturbing behaviors' (B = .17, p = .026), 'caregiver's educational level'(B = .03. p=.036), 'family income'(B=.08. p=.041) were significant predictors of 'total subjective burden': 'positive disturbing behaviors'(B=.32. p=.066). 'negative disturbing behaviors'(B=.24, p=.096) 'durations of illness'(B= .03. p= .079) were significant predictors of 'stigma' 'negative disturbing behaviors'(B=.28. p=.005). 'patient sex'(B=-.32. p=.022). 'positive disturbing behaviors'(B=.28. p=.020), 'patient age'(B=.02. p=.010), 'caregiver age'(B=-01, p= .002) were significant predictors of 'grief' 'negative disturbing behaviors'(B= .28, p= .005). 'patient sex'(B= -.32. p=.039), 'caregiver age'(B=-.02, p= .023). 'caregiver's educational level'(B= .04, p = .044) were significant predictors of 'worry' 'patient sex'(B=-.46. p=.005). 'negative disturbing behaviors'(B= .28. p=.018), 'caregiver age'(B=-.01, p=.037) were significant predictors of 'pity' 'positive disturbing behaviors'(B=.83. p=.000). 'patient' contributions' (B = .22, p =.017). 'family income'(B=.09. p=.65) were significant predictors of 'fear' 'positive disturbing behaviors'(B=.49, p=.001). 'negative disturbing behaviors'(B= .24. p=.057) 'patient sex'(B=-.4l, p=.017), 'family income'(B=.14, p=.047) were significant predictors of 'dispair'. 3) Hierardhical regression of 'positive relationship' showed that 'patient contributions'(B=.32, p=.000). 'negative disturbing behaviors'(B= .24, p= .005), 'patient sex'(B=-.23, p=.036).

A cyclic undecapeptide-family natural product, cyclosporin A (CyA), which is one of the most valuable immunosuppressive drugs, is produced nonribosomally by a multifunctional cyclosporin synthetase enzyme complex in a filamentous fungal strain named Tolypocladium niveum. Previously, structural modifications of cyclosporins such as a regionspecific hydroxylation at the $4^{th}$ N-methyl leucine in a rare actinomycetes called Sebekia benihana were reported to lead to dramatic changes in their bioactive spectra. However, the reason behind this change could not be determined since a system to genetically manipulate S. benihana has not yet been developed. To address this limitation, in this study, we utilized the most commonly practiced gene manipulation techniques including conjugation-based foreign gene transfer-and-expression as well as targeted gene disruption to genetically manipulate S. benihana. Using these optimized genetic manipulation systems, a putative cytochrome P450 hydroxylase (CYP) gene named CYP506, which is involved in CyA hydroxylation in S. benihana, was specifically disrupted and genetically complemented. The S. benihana${\Delta}$CYP506 exhibited a significantly reduced CyA hydroxylation yield as well as considerable yield restoration by functional complementation of the S. benihana CYP506 gene, suggesting that the genetically manipulated S. benihana CYP mutant strains may serve as a more efficient bioconversion host for various valuable metabolites including CyA.

An asteroid family is a population of asteroids in the proper orbital element space (a, e, i), considered to have been produced by a disruption of a large parent body presumably through a catastrophic collision. Asteroid families offer unique opportunities to reconstruct and characterize the break-up history of airless bodies in the main-belt. The Maria family is a typical old population (~3${\pm}$1 Gyr) of asteroids that have undergone significant collisional and dynamical evolution in the history of the inner Solar System; it is also believed to be one of the candidate source regions for giant S-type near-earth asteroids (NEAs). However, to date, physical characteristics of this family members such as rotational periods have been known only for 61 of the larger asteroids among 3,230 objects, which accounts for less than 2 percent of the family. In this presentation, we provide some preliminary results of our recent study: out of more than dozen of the family members, lightcurves for eight objects have been obtained for the first time. We plan to increase the number of target objects, and investigate evidences for the Yarkovsky/YORP effect on Maria family based on our observations.

This study estimates the role of public and private income transfer to the income status of women who experienced marital disruption. In detail, this study estimates five major subjects (1) women's socioeconomic background, (2) income and poverty status, (3) family income composition, (4) the anti-poverty effect of public and private income transfers, and (5) factors associated with women's poverty status. Major findings of the study are as follows: First, women's socioeconomic characteristics, income status, and poverty status are different according to what types of marital disruption (separation, divorce, death of spouse) they experienced. Second, the role of public and private income transfers to reduce women's poverty are also different according to their marital status. Third, widow's working condition and the level of public assistance are significantly associated with the poverty status of widow.

An asteroid family is a group of asteroidal objects in the proper orbital element space (a, e, and i), considered to have been produced by a disruption of a large parent body through a catastrophic collision. Family members usually have similar surface properties such as spectral taxonomy types, colors, and visible geometric albedo with a same dynamical age. Therefore an asteroid family could be called as a natural Solar System laboratory and is also regarded as a powerful tool to investigate space weathering and non-gravitational phenomena such as the Yarkovsky/YORP effects. We carry out time series photometric observations for a number of asteroid families to obtain their physical properties, including sizes, shapes, rotational periods, spin axes, colors, and H-G parameters based on nearly round-the-clock observations, using several 0.5-2 meter class telescopes in the Northern hemisphere, including BOAO 1.8 m, LOAO 1.0 m, SOAO 0.6 m facilities in KASI, McDonald Observatory 2.1 m instrument, NARIT 2.4 m and TUG 1.0 m telescopes. This study is expected to find, for the first time, some important clues on the collisional history in our Solar System and the mechanisms where the family members are being transported from the resonance regions in the Main-belt to the near Earth space.
