The purpose of this study was to investigate the developmental pathways that mediate the effects of child abuse on delinquency. Data from the first wave of 'Seoul Panel Study of Children(SPSC)' were analyzed. The subjects consisted of 1,811 4th grade students from elementary schools. Structural equation model was employed for statistical analyses. The results showed that the relationship between child abuse and delinquency was indirectly mediated by self-esteem, peer rejection, and school attachment. The hypothesized structural model had a good model fit. Abused children were more likely to have low self-esteem, which was associated with higher levels of delinquency. In addition, abused children were more likely to be rejected by peers and to have low school attachment, which was also associated with higher levels of delinquency. Implications for social work practice from this study were discussed.

This study was conducted to develop a parent's autobiography writing program and to verify its effectiveness. The subjects were 82 college students(52 students in the experimental group and 30 students in the control group) in an university in Seoul. The research design was a nonequivalent control group pretest-posttest quasi-experimental design. The effectiveness of the program was verified by ANCOVA using the SPSS 23.0 program. Parent's autobiography consisted of prologue, childhood, adolescence, adulthood, and epilogue. Each chapter of the autobiography consisted of a part of the growth narrative describing the main events of the parents and a part of the introspection narrative describing the writter's feelings. As a result of analysis, first, the parent's autobiography writing program significantly promoted parent-child relationships. Second, parent's autobiography writing programs significantly increased parent-child attachment. Third, parent's autobiography writing programs showed a significant increase in parent-child communication. Based on the results of this study, we discussed the effect and application possibility of the parent's autobiography writing program.

Purpose: (1) To evaluate the trabecular pattern at the femoral attachment of the posterior cruciate ligament (PCL) in patients with a PCL injury; (2) to analyze bone microarchitecture by applying gray level co-occurrence matrix (GLCM)-based texture analysis; and (3) to determine if there is a significant relationship between bone microarchitecture and posterior instability. Materials and Methods: The study included 96 patients with PCL tears. Trabecular patterns were evaluated on T2-weighted MRI qualitatively, and were evaluated by GLCM texture analysis quantitatively. The grades of posterior drawer test (PDT) and the degrees of posterior displacement on stress radiographs were recorded. The 96 patients were classified into two groups: acute and chronic injury. And 27 patients with no PCL injury were enrolled for control. Pearson's correlation coefficient and one-way ANOVA with Bonferroni test were conducted for statistical analyses. This protocol was approved by the Institutional Review Board. Results: A thick and anisotropic trabecular bone pattern was apparent in normal or acute injury (n = 57/61;93.4%), but was not prominent in chronic injury and posterior instability (n = 31/35;88.6%). Grades of PDT and degrees of posterior displacement on stress radiograph were not correlated with texture parameters. However, the texture analysis parameters of chronic injury were significantly different from those of acute injury and control groups (P < 0.05). Conclusion: The trabecular pattern and texture analysis parameters are useful in predicting posterior instability in patients with PCL injury. Evaluation of the bone microarchitecture resulting from altered biomechanics could advance the understanding of PCL function and improve the detection of PCL injury.

Purpose: The purpose of this study was intended to examine the importance and role of social capital in the local community, and empirically identify the relationships among the social capital, community spirit, resident satisfaction, and community participation of the residents of urban-rural complex areas. Methods: This study conducted a survey was conducted with residents of the urban-rural complex areas to collect data, and the data were statistically and empirically analyzed to verify the hypothesis. Results: As a result of the study, first, networks and trust as local social capital were found to have positive effects on local attachment. Second, networks and trust were found to have positive effects on social ties. Third, local attachment and social ties were found to have positive effects on resident satisfaction. Finally, community participation was found to have moderating effects on the relationship between social ties and resident satisfaction. Conclusion: Through this study, the importance and role of local social capital in urban-rural complex areas, where regional problems are highly likely to occur, were reviewed, and basic data necessary to solve the social problems at hand in urban-rural complex areas and promote continuous development were provided can be said to be the significance of this study.

Loving-kindness and compassion meditation (LKCM) is known to be effective in improving mental health and interpersonal relationships. An exploratory pilot study was conducted with the aim of examining the feasibility of LKCM which known to be effective in improving mental health and interpersonal relationships for pregnant women. Measures of stress, depression, maternal fetal attachment, mindfulness and self-compassion of subjects (n=8) were obtained at baseline, and after a 4-weeks LKCM program to identify effectiveness and supplements. Based on a focus group interview, phenomenological analysis was also conducted. The results showed that improvement potential of psychological comfort, positive relationship with fetus as well as complementary points for session contents and home training. We hope that this study will broaden understanding for the development of LKCM for pregnant women and promote further research.

This study intends to analyse the concept on the child-rearing of parents. Through analysis, several concepts on the child-rearing would be cleared, and therefore the groundwork of the theoretical framework can be constructed. The concepts were analyzed by the method of Walker & Avant(1995). The attribute of child-rearing is as follows; nutrition supply, affectionate mind, caring, growth development supporting, protecting, instructing, pregnancy, delivery etc. The proper child-rearing helps reinforce child development, mother-infant attachment, social disposition, parental-role contentment and family relationship. This study would be helpful to the establishment of child-rearing paradigm. And therethrough this result although helps construct proper child-rearing as well as theoretical groundwork.

본 연구에서는 고향의 개념을 의미론적 측면과 지리학적 입장에서 정의하고, 한국 사람들이 고향이라고 지칭하는 고향의 공간적 대상, 고향에 대한 감정과 선호, 고향의 지리적 특징 및 이미지 등을 조사하여, 이를 중심으로 한국인의 고향에 대한 애착의 본질과 정서(ethos)를 밝히려 하였다. 그 결과는 다음과 같다. 첫째, 한국인의 고향에 대한 애착은 본질적으로 고향 의식과 회귀본능과 같은 고향에 대한 인류의 보편적 정서로부터 나온 것이다. 둘째. 이러한 보편적 정서 위에 한국의 사회적 배경에서 나오는 고유한 고향의식이 첨가되었다. 사회적 배경에서 발생된 고향에 대한 강한 애착은 효에 근본을 둔 유교적 전통, 남북분단, 도시화에 따른 광범위한 실향의 결과에 의해서 형성된 정서라고 볼수 있다. 섯째, 고향이미지는 이러한 한국의 정서를 반영하고 있으며, 자연환경적, 인문환경적, 감각적 요소가 모두 수렴된 전형적이며, 추상화된 유형으로 나타난다. 넛째, 한국인의 고향에 대한 정서는 인간의 본성으로부터 나오는 보편적 정서와 대체로는 일치하지만 개인이나 집단의 인구.사회적 배경과 공간적 체험에 따라 다른 것으로 나타났다.

In the last thirty years, societal changes have affected Korean families at a fast pace. Some of these changes include the fall of childbirth rate, expansion of women in the workforce, delay of first marriages, and rise of divorces, remarriages, and international marriages. These new trends have created and diversified new contexts for family structures and parent-child relationships. Both parents and children are now confronted with a myriad of new challenges and in need of understanding the newly transformed-family environments in respond to new ecological pressures. Contemporary issues concerning parent-child relationships are discussed by analyzing the new trends and research issues on particular social issues and pressures. Future policy issues are discussed based on these analyses combined with the critical impact of the parent-child relationships on child development.

The purpose of this study is to evaluate the emission reduction characteristics depending on the formation of the catalyst which influences the development of the diesel oxidation catalyst (DOC) suitable for small-sized diesel engines. We also attempted to suggest the feasibility of it as an after-treatment device. The reduction efficiency of DOC for CO and HC was proportional to the contents of precious metals, and the particulate matter (PM) has been reduced as much as 53∼59%. The reduction rate of soluble organic fraction (SOF) by DOC attachment revealed 100%. The composition of sulfate in PM increased from 3%, 7∼11% by installation of DOC. It is described that increase of sulfate contributed to the production of PM. This result also showed that the SOF and sulfate have trade-off relationship.

In this paper, the kinematic model and motion control of a joint-actuated mobile robot are analyzed. To take an efficient approach to the wheeled mobile robots, the relationship between wheel rotation and the contact point of the wheel is considered. It is shown that each addition of a joint to a mobile robot increases the degree of freedom(DOF) of mobile robot, and the way of joint attachment to a mobile robot is proposed. To get a solution of inverse kinematics of mobile robot, two types of approaches are proposed.
