Purpose: This study used a system dynamics methodology to identify correlation and nonlinear feedback structures among factors affecting adolescent cyberbullying victims (CV) in Korea and to construct and verify a simulation model. Methods: Factors affecting CV were identified by reviewing a theoretical background in existing literature and referencing various statistical data. Related variables were identified through content validity verification by an expert group, after which a causal loop diagram (CLD) was constructed based on the variables. A stock-flow diagram (SFD) using Vensim Professional 7.3 was used to establish a CV model. Results: Based on the literature review and expert verification, 22 variables associated with CV were identified and the CLD was prepared. Next, a model was developed by converting the CLD to an SFD. The simulation results showed that the variables such as negative emotions, stress levels, high levels of conflict in schools, parental monitoring, and time spent using new media had the strongest effects on CV. The model's validity was verified using equation check, sensitivity analysis for timestep and simulation with 4 CV adolescent. Conclusion: The system dynamics model constructed in this study can be used to develop intervention strategies in schools that are focused on counseling that can prevent cyberbullying and assist in the victims' recovery by formulating a feedback structure and capturing the dynamic changes observed in CV. To prevent cyberbullying, it is necessary to develop more effective strategies such as prevention education, counseling and treatment that considers factors pertaining to the individual, family, school, and media.

Pharyngeal pouches, a series of outgrowths of the pharyngeal endoderm, are a key epithelial structure governing facial skeleton development in vertebrates. Pouch formation is achieved through collective cell migration and rearrangement of pouch-forming cells controlled by actin cytoskeleton dynamics. While essential transcription factors and signaling molecules have been identified in pouch formation, regulators of actin cytoskeleton dynamics have not been reported yet in any vertebrates. Cofilin1-like (Cfl1l) is a fish-specific member of the Actin-depolymerizing factor (ADF)/Cofilin family, a critical regulator of actin cytoskeleton dynamics in eukaryotic cells. Here, we report the expression and function of cfl1l in pouch development in zebrafish. We first showed that fish cfl1l might be an ortholog of vertebrate adf, based on phylogenetic analysis of vertebrate adf and cfl genes. During pouch formation, cfl1l was expressed sequentially in the developing pouches but not in the posterior cell mass in which future pouch-forming cells are present. However, pouches, as well as facial cartilages whose development is dependent upon pouch formation, were unaffected by loss-of-function mutations in cfl1l. Although it could not be completely ruled out a possibility of a genetic redundancy of Cfl1l with other Cfls, our results suggest that the cfl1l expression in the developing pouches might be dispensable for regulating actin cytoskeleton dynamics in pouch-forming cells.

본 연구는 저소득층의 4년제 대학진학을 제약하는 두 가지 요인, 즉 등록금 납부여력 부족과 불우한 성장환경의 누적적 영향에 따른 학업능력 부족 중 무엇의 영향이 더 큰지 살펴보았다. 희귀분석 결과, 중학교 시기의 학업성취와 몇몇 가정배경 변수들은 유의한 반면, 이들 변인 통제 시 대학진학 시기의 가구소득은 4년제 대학 진학에 거의 영향을 주지 못했다. 또한 Carneiro and Heckman(2003)이 미국 고등교육 격차 원인규명을 위해 수행한 분석을 한국 상황에 적용해 본 결과, 학업능력 및 가정배경의 격차로 4년제대에 진학하지 못하는 비율이 등록금 납부가 어려워 진학하지 못하는 비율을 크게 능가했다. 이는 등록금 인하와 같은 단기적 제약요인의 완화만으로는 대입격차문제 해결이 힘듦을 시사한다.

본 연구는 손자녀 양육지원을 거부한 조모의 경험을 살펴봄으로써 손자녀 양육을 지원하고 있는 가족 및 노년기 여성에 대한 이해를 풍부하게 하는데 목적이 있다. 이를 위해 가족 내에서돌봄 역할을 주로 맡아온 조모를 대상으로 이들이 손자녀 양육을 수용하지 않은 계기와 맥락, 이를 둘러싼 가족관계 경험을 탐색해 보고자 하였다. 이를 위해 질적 연구방법 중 현상학적연구방법을 활용하였으며 손자녀 양육지원을 '거부한' 경험이 있는 노년기 여성 7명이 참여하였다. 연구결과, 첫째 이들은 손자녀 양육에서 오는 부담감과 연장된 어머니 역할에 대한 거부감, 가족 간 갈등발생 우려로 손자녀를 돌보지 않기로 하였으나, 성인자녀의 요청을 거절한 것에 대해 미안함을 느끼고 있었다. 둘째, 이들의 돌봄지원 거부 결정은 가족 구성원의 다양한역동을 야기했으나 이들은 심리적 어려움을 경험하면서도 나름의 방식으로 성인자녀들의 요구에 대응하며 자신의 결정을 관철하고 있었다. 셋째, 노년기 여성들은 손자녀 양육을 성인자녀들의 과업 혹은 사회가 책임져야 할 문제로 인식하고 있었으며, 가족과 사회가 여성 노인에게돌봄 책임을 전가한 것으로 인식하고 있었다. 이러한 연구결과는 돌봄 및 가족관계에 대해 과거 노인세대와 다른 관점을 가진 여성 노인들이 등장했다는 점, 전통적인 젠더 인식과 가족돌봄 규범에 균열과 변화가 발생했다는 점을 확인해준다. 이는 돌봄지원 정책에 수립 시 이들의 관점을 보다 적극적으로 반영해야 할 필요성이 있음을 시사한다. 이를 바탕으로 손자녀 양육을 지원하고 있는 가족 및 노년기 여성을 위한 실천적 정책적 개입 방안을 제시하였다.

This study compares how mother-daughter differentiation influences solidarity and relationship satisfaction between mothers-in-law and sons-in-law. The subjects of this study were 167 mothers-in-law (mean age, 59.6 years) paired with their sons-in-law (mean age, 36.9 years). Participants were given quantitative survey questionnaires on their relationships. Descriptive statistical analyses were conducted for the social and demographic characteristics of mothers-in-law and sons-in-law. Ordinary least square multiple regression analyses were also conducted to examine the level of mother-daughter differentiation, solidarity, and relationship satisfaction between mothers-in-law and sons-in-law. The results show that a higher age of the mothers-in-law results in lower relationship satisfaction between mothers-in-law and sons-in-law. Next, an increase the level of mother-daughter differentiation (which means more balance between intimacy and detachability) results in a higher overall solidarity, affectual solidarity, giving functional solidarity, and consensual solidarity between mothers-in-law and sons-in-law. However, there was no statistically significant difference in the receiving functional solidarity and normative solidarity between mothers-in-law and sons-in-law. Finally, the results show that a higher level of mother-daughter differentiation produces a higher relationship satisfaction between mothers-in-law and sons-in-law. The findings could provide a better understanding of inter-generational relationships in Korean family dynamics. The results also have implications for providing counseling for the development of healthy relationships between mothers-in-law and sons-in-law.

The purpose of this study was to develop a program for the enhancement of Korean married women's quality of life(LQ) based on the results of the first year study(1996) and the second year research(1998). In order to construct a program, a psycological type test was conducted to 505 women and four preliminary programs were carried out focusing on self-esteem, understanding of one's own personality dynamics, efficient communication, positive emotion, social belongingness and expressions of feelings of unfinished business. For the final program, Jung's theory of psychological type(MBTI, Satir's family therapy approach and psychodrama were applied. An experimental and a control group were designed consisting 16 women for each group. The program was carried out for 6 weeks for the experimental group. The result of treatment were as follows: 1) There was a difference statistically in LQ related to family harmony, serif-achievement and improvement of relationship with in-laws. 2) There was a statistical change in psychological factors of expression of feelings, self-esttem, communication, and positive emotions. 3) The program participants self reports indicate that the program was effective for the reconstruction of family relationship, self-understanding, group coherence, and instigation of hope. The reports also shows that the program was effective for the perceptual changes in parent-child, wife-husband and siblings' relationships. In conclusion, the program developed for the enhancement of Korean married women's life quality(LQ) based on the Jung's psychological type theory, Satir's family therapy approach and psychodrama was erective for the improvement of LQ.

This study examined the trajectories of the marital satisfaction among middle and old aged couples for 8 years. This study focused on middle and old aged couples who were relatively uninterested in family research. Using the 1-5 Waves of Korean Longitudinal Study of Ageing (KLoSA) 2006-2014, the study included 635 middle and old aged couples whose husbands were 65-74 years old at baseline. First, a latent growth model indicated that a husband's and wife's marital satisfaction trajectories decreased over time. Second, a parallel latent growth model indicated that a husband's marital satisfaction trajectories decreased more quickly, when the initial level of their own marital satisfaction was higher (husband's actor-effect); in addition, a wife's marital satisfaction trajectories also decreased more quickly, when the initial level of their own marital satisfaction was higher (wife's actor-effect). Wife's marital satisfaction trajectories decreased more slowly, when the initial level of their husband's marital satisfaction was higher (husband's partner-effect); however, the husband's slope was not associated with the initial level of their wife's. The methodological value of this work shows the application of a parallel latent growth model that includes the actor and partner effect of APIM. The findings extend our understanding of longitudinal marital dynamics between couples and promote a study on the trajectories of marital satisfaction at stages of the family life cycle.

이 연구의 목적은 메타경로분석의 방법론을 적용해 최근 부모수당제도의 도입을 중심으로 독일의 일-가정 양립정책과 젠더레짐의 변화의 실제와 동학을 규명하는 것이다. 일-가정 양립정책에서 '계층화'가 이루어지고 있는데, 정치적 장벽이 해소돼 부모수당제도를 도입할 수 있었던 반면 기존 가족주의 지지세력의 제도 내부적 장벽으로 인해 아동양육수당제도를 고수하지 않을 수 없었다. 그러나 부모수당제도는 '차별적인 성장'으로 활성화돼 독일 젠더레짐의 지배적인 구조를 '순차적 양립'에서 '동시적 양립'으로 변화시키는 핵심적인 보완성의 변화를 낳고 있다. 한편 주요 정치적 행위자들은 젠더영역에 대한 '의도적 분리'를 통해 전체 독일모델의 핵심적인 제도영역 간의 조정관계의 이완 가능성을 차단하려 하고 있다.

The purpose of this study was to investigate the contexts in which employed mothers with young children consider leaving the labor force. We used a mixed methods design, which integrates the findings of quantitative and qualitative analyses, to better understand the dynamics underlying employed mothers' intentions to leave the labor force. The participants of both quantitative (N = 324) and qualitative (N = 16) data were married mothers who were employed full-time and had at least one child younger than elementary-school age at the time of data collection. Both the quantitative analysis of logistic regression and the qualitative thematic analysis revealed that the child's age, the husband's income, the utilization of child care by relatives, the mother's job involvement, family-to-work role conflict, and other costs and rewards of participation in the work force were the important contexts where employed mothers considered leaving the labor force. The quantitative analysis uniquely found that being employed at a workplace with flexible work hours were associated with lower odds of considering exit from the labor market. The qualitative analysis highlighted that the decision to leave the labor force or to stay in it is a complicated issue that almost all employed mothers potentially face at some point in their careers. These findings suggest that policy support is warranted to help employed mothers with young children remain in the workforce when they wish to.

The plant hormone auxin is involved in all stages of plant development. Aux/IAAs are the transcriptional repressors that bind to the Auxin Response Factors (ARFs) to regulate the gene expression upon auxin release. Aux/IAA have highly conserved C-terminal domains (domains III-IV) that mediate both homotypic and heterotypic interactions between Aux/IAA and ARF family proteins. Recent studies revealed that the conserved domains III-IV share a common ${\beta}$-grasp fold that oligomerizes in a front-to-back manner. In particular, Aux/IAA contains a mobile insert helix in the domain III-IV, whereas ARFs do not. Here, we investigated the dynamics of the insert helix using paramagnetic NMR spectroscopy. The insert helix exhibited fast motions in the ps-ns time scale from $^{15}N$ relaxation data, but the amplitude of the motion is likely limited to the local neighborhood. Our result suggests that the motion of the helix may have functional implications in protein-protein interactions for transcriptional regulations.
