This study examined the relationships between place attachment to home, acculturative stress, and psychological adjustment among Korean youth in the United States. In particular, this study sought to better understand how place attachment to home and acculturation stress impacts upon youth's psychological adjustment, as measured by depression and self-esteem. The subjects consisted of 225 Korean youths (113 males and 111 females) residing in Michigan in the USA, of whom 47.6% attended middle school while 52.4% of whom attended high school. The instruments utilized were the acculturative stress scale (Sandhu and Asrabadi, 1994), the place attachment scale (Choi, Lee, & Han, 2009), Radloff's depression scale (CES-D), and Rosenberg's self-esteem scale. Hierarchical multiple regression analyses were used to assess the predictive effects of place attachment to home and acculturative stress on youth's psychological adjustment, alongside controlling demographic variables. The findings indicated that place attachment to home and acculturative stress impacted upon depression and self-esteem, as experienced by the youths examined. These results have implications for our understanding of the importance of both youths' place attachment to home and acculturative stress in the acculturation process.

This study was conducted to identify the characteristics of paternal and maternal grandmothers' social support, and to investigate the relationship between paternal and maternal grandmothers' social support and their school-aged grandchildren's psychological adaptation. The participants of this study were 215 students in the 5th and 6th grades and their mothers residing in Daegu. Collected data were analyzed using t-test, paired t-test, ANOV A, Scheffe's test, and hierarchical multiple regression. Findings of this study are as follows: 1. School-aged children perceived that their maternal grandmothers rendered more emotional and informational support than their paternal grandmothers. 2. Paternal grandmother's social support as perceived by the grandchild varied significantly with the frequency of face-to-face contact, the frequency of phone contact, and the friendship between the paternal grandmother and the mother. Maternal grandmother's social support as perceived by the grandchild, on the other hand, varied significantly by the level of grandmother's education, the frequency of face-to-face contact, and the frequency of phone contact. 3.

Purpose: The purpose of this study was to analyze the smoking behaviors and to identify the impact of depression, temperament, and characteristics of smoking experience on rural adolescents. Method: A survey using a self-administered questionnaire was done of 310 rural high school students. Using SPSS 12.0, Pearson correlation coefficients and multiple regression were used to analyze the data. Results: The smoking rate of rural high school students was higher than that of the national rate for this age group. Serious depression was observed in the rural high school students. There was a positive correlation among smoking experience, school records, novelty seeking and a negative correlation between smoking and cooperativeness. The significant predictors of smoking experience were type of school, satisfaction with school, school records, novelty seeking, reward dependence and cooperativeness. These factors accounted for 38.9% of variances in the smoking experience of rural adolescents. Conclusion: These results suggest that adolescents who exhibit factors identified in this study are regarded as having the potential to smoke, and this result proposes the basis for program development for the prevention of smoking and smoking cessation.

The Nuclear Power Plant(NPP) industry in Korea has been making efforts to reduce the human errors which have largely contributed to about 150 nuclear reactor trips since 2001. Recently, the Crew Resource Management(CRM) training has risen as an alternative countermeasure against the nuclear reactor trips caused by human errors. The effectiveness of CRM training in NPP industry, however, has not been proven to be significant yet. In this study a return on investment(ROI) model is developed to measure the effectiveness of CRM training for the operators in Korean NPP. The model consists of mathematical expressions including multiple variables affecting the CRM training impacts and nuclear reactor trips. Implication of the model is discussed further in detail.

The disposal of stormwater is one of the major problems in urban water management. One method of reducing peak runoff rates and other detrimental impacts of stormwater is detention storage. Detention ponds as a water quality control alternatives have been investigated by a number of researchers. Recognizing multiple roles such as flood peak attenuation, pollution removal and aesthetic enhancement, the design and management of detentions ponds deserve more research. The purpose of this research is to establish design criteria wet detention ponds to improve water quality. Water quality in detention pond discharge might be improve with physical, chemical and biological alterations. Physical alteration was focused in this study. There are several methods for estimating the suspended solid control capability of wet detention ponds. Existing models of suspended solids removal are based on sedimentation and gravity settling theory. The pollutant trap efficiency of pond is a function of several interrelating factors. Detention time is the most important factor, because it determine gravity settling quantities of pollutants. Desirable modification of physical factors for improvement of water quality in wet detention ponds are volume ratio, area ratio, length to width ratio, depth, out let location, bottom soil type. In order to apply design procedure in actual site, Namak new town development area was selected.
