The main purpose of this study is to explore the relationship between perceived the authoritarian parenting style and academic achievement among college students. Specifically, it is hypothesized that authoritarian parenting would indirectly affect the academic achievement of college students through self-differentiation level and career decision-making self-efficacy. 283 college students, after the consideration of their grade and gender, were selected for this study as participants. Methods describing the primary analytical technique of Structural Equation Modeling were used for the study. The results demonstrate that an authoritarian parenting style negatively affected the academic achievement of college students. There are mediation effects of self-differentiation and career decision-making self-efficacy between the perceived authoritarian parenting style and academic achievement among college students. The findings imply that the positive development of adult children requires more egalitarian parenting styles than those used on early adolescents. Next, for female students, specialized career counseling programs focusing on reducing psychological career barriers and career stress are needed. Lastly, it is implied that parenting styles used on adult children in Korea may differ from Western styles. Therefore, it may be difficult to explain the relationship between parents and adult children with a traditional theoretical framework.

The paper gives an overview of the problems to be tackled nowadays by occupational health with regards to shift work as well as the main guidelines at organizational and medical levels on how to protect workers' health and well-being. Working time organization is becoming a key factor on account of new technologies, market globalization, economic competition, and extension of social services to general populations, all of which involve more and more people in continuous assistance and control of work processes over the 24 hours in a day. The large increase of epidemiological and clinical studies on this issue document the severity of this risk factor on human health and well being, at both social and psychophysical levels, starting from a disruption of biological circadian rhythms and sleep/wake cycle and ending in several psychosomatic troubles and disorders, likely also including cancer, and extending to impairment of performance efficiency as well as family and social life. Appropriate interventions on the organization of shift schedules according to ergonomic criteria and careful health surveillance and social support for shift workers are important preventive and corrective measures that allow people to keep working without significant health impairment.

The blade vibration problem of bladed disk is the most critical subject to consider since it directly affects the stable performance of the engine as well as life of the engine. Especially, due to complicated vibration pattern of the bladed disk, more effort was required for vibration analysis and test. The research of measuring the vibration of the bladed disk, using NSMS(Non-intrusive stress measurement) instead of Aeromechanics testing method requiring slip ring or telemetry system with strain gauge, was successful. These testing can report the actual stresses seen on the blades; detect synchronous resonances that are the source of high cycle fatigue(HCF) in blades; measure individual blade mis-tuning and coupled resonances in bladed disks. In order to minimize the error being created due to heat expansion, the tip timing sensor is installed parallel to the blade trailing edge, yielding optimal result. Also, when working on finite element analysis, the whole bladed disk has gone through three-dimensional analysis, evaluating the family mode. The result of the analysis matched well with the test result.

To investigate the reliability, validity of posttraumatic growth among Korean cancer caregiver, 295 participants were asked to complete a Korean posttraumatic growth inventory, translated from the Posttraumatic Growth Inventory (PTGI; J Trauma Stress 1996; 9: 455.471), together with the Caregiver burden scale, life style interruption scale, economic burden scale and positive adaptation scale, social support scale and questions about religious and demographic factors. Cronbach's alpha was 0.95 for the K-PTGI, indicating sufficient internal consistencies. Construct and Criterion validity were also supported. K-PTGI appeared to be a sound measure for the experience of posttraumatic growth in cancer caregivers and this study result will be able to contribute to facilitate future research.

Using meta-analysis, this study aims to examine individual, familial, and social support variables in relation to acculturative stress by in order to draw implications for social welfare practice and policy. For the purpose of this study, authors selected 37 studies between 2000 and 2013. Results are as follows: First, acculturative stress of marriage-based migrant women showed statistically significant average effect size in individual, familial, and social support variables. Second, each variable showed at least 'medium' and above size. Further, marital satisfaction and social support showed 'large effect size' and life satisfaction, family relations and functions, self-esteem, psychological well-being, and depression showed 'near large effect size.' Third, when moderating effect was examined, Korean language proficiency, economic difficulty, depression, and self-esteem among individual variables showed differences in effect size according to socio-economic variables. Meanwhile, marital satisfaction and couple relationship among familial variables and social support among social variables showed differences in effect size according to socio-economic variables. Based on these results, authors suggested ways to prevent or reduce acculturative stress among marriage-based migrant women in Korea.

Reactive oxygen species generated under oxidative stress are involved in neuronal diseases, including ischemia. Glutathione S-transferase pi (GSTpi) is a member of the GST family and is known to play important roles in cell survival. We investigated the effect of GSTpi against oxidative stress-induced hippocampal HT-22 cell death, and its effects in an animal model of ischemic injury, using a cell-permeable PEP-1-GSTpi protein. PEP-1-GSTpi was transduced into HT-22 cells and significantly protected against H2O2-treated cell death by reducing the intracellular toxicity and regulating the signal pathways, including MAPK, Akt, Bax, and Bcl-2. PEP-1-GSTpi transduced into the hippocampus in animal brains, and markedly protected against neuronal cell death in an ischemic injury animal model. These results indicate that PEP-1-GSTpi acts as a regulator or an antioxidant to protect against oxidative stress-induced cell death. Our study suggests that PEP-1-GSTpi may have potential as a therapeutic agent for the treatment of ischemia and a variety of oxidative stress-related neuronal diseases.

This study aims to analyze the influence of organizational support perception of workers in medical institutions on intrinsic job motivation, and to check whether there is significance in the mediating effect of work-family conflict and work-family balance factors in this process. The results of empirical analysis through the questionnaire are as follows. First, it was confirmed that organizational support recognition had a significant positive effect on work-family balance as well as intrinsic job motivation, and work-family balance had a significant positive effect on intrinsic job motivation. Second, it was confirmed that organizational support recognition had a significant negative effect on work-family conflict, but work-family conflict had no significant influence on intrinsic job motivation. Third, in order to reduce job stress for medical institution workers, it is necessary to reduce job intensity, assign appropriate workload for ability. And in order to improve manpower operation and job efficiency, Job training and staffing in the right place are needed. Fourth, in order to improve positive organizational support perception and intrinsic job motivation, It is necessary to induce long-term service by providing support and institutional devices to increase attachment to the current job and recognize organizational problems as their own problems with various incentive systems. The limitations of this study and future research directions are as follows. First, it is believed that an expanded analysis of medical institution workers nationwide by region, gender, medical institution, academic, and income will not only provide more valuable results, but also evaluate the quality of medical services. Second, it is necessary to reflect the impact of the work-life balance support system on each employee depending on the environmental uncertainty or degree of competition in the hospital to which medical institution workers belong. Third, organizational support perception will be recognized differently depending on organizational culture and organizational type, and organizational size and work characteristics, working years, and work types, so it is necessary to reflect this. Fourth, it is necessary to analyze various new personnel management techniques such as hospital's organizational structure, job design, organizational support method, motivational approach, and personnel evaluation method in line with the recent change in the government's medical institution policy and the global business environment. It is also considered important to analyze by reflecting recent and near future medical trends.
