The purpose of this study was to investigate the influence of covert narcissism and self control on the daily stresses encountered by school-age boys and girls. The subjects were 517 children who attended in elementary schools in Daegu and Gyeongbuk Province. Self reporting questionnaires were used to investigate covert narcissism, self control and daily stresses. The data thus collected were analyzed by means of Pearson's correlation, multiple regression, using SPSS Win 19.0. The results are as follows. (1) In term of daily stresses, the regression findings indicated the main effect of covert narcissism and self control. Daily stresses increased as school-age boys' and girls' covert narcissism increased or their self control decreased. (2) Covert narcissism influenced more on daily stresses than self control did for both boys and girls. (3) There were significant interactions between school-age girls' covert narcissism and self control in term of daily stresses.

This study is aimed at determining stress and the degree of stress coping among nurse as well as such general characteristics as daily life styles, duty, and socio-demographic characteristics of that group. 525 nurses, from four university hospitals in Daejeon city underwent a self-administered questionnaire during the 3-week period from July. 21 to August. 9, 2003. The questions focused on general characteristics including： socio-demographic and duty characteristics, daily life styles, and stress and methods of coping with stress. Based on the distribution of degree of stresses, 66.1% of the study subjects were at the potential risk of stress, with the high risk group constituting 30.3% and the normal group 3.6%. The stress and the degree of stress coping were shown to be affected by socio-demographic and job-related characteristics as well as daily life styles. The group at higher risk of stress was shown to have a lower degree of coping with stress, implying that a lower degree of coping with stress would in turn heighten the occurrence of stress. Therefore, it is required to develop an effective strategy that includes stress-reduction programs available in the field and prompting further build-up of comprehensive stress-management programs.

Determining 'photosynthetically active radiation' (PAR) is a key part of calculating phytoplankton productivity in a biogeochemical model. We explore the daily and seasonal variability in the ratio of PAR irradiance to total irradiance that occurred at Ieodo Ocean Research Station (IORS) in the East China Sea under clear-sky conditions in 2004 using a simple radiative transfer model (RTM). Meteorological data observed at IORS and aerosol optical properties derived from Aerosol Robotic Network observations at Gosan are used for the RTM. Preliminary results suggest that the use of simple PAR irradiance-ratio values is appropriate in calculating phytoplankton productivity as follows: an average of $0.44\;({\pm}0.01)$ in January to an average of $0.48\;({\pm}0.01)$ in July, with average daily variabilities over these periods of about $0.016\;({\pm}0.008)$ and $0.025\;({\pm}0.008)$, respectively. The model experiments demonstrate that variations in the major controlling input parameters (i.e. solar zenith angle, precipitable water vapor and aerosol optical thickness) cause PAR irradiance ratio variation at daily and seasonal timescales. Further, increases (>0.012) in the PAR irradiance ratio just below the sea-surface are positively correlated with high solar zenith angles and strong wind stresses relative to those just above the sea-surface.

Unlike daily hassles or minor stressors, immigration is an intense life event that may cause excessive stress. In particular, immigrant parents find themselves in a more stressful situation in that they experience stresses caused by immigration and stresses caused by parenting at the same time. The purpose of this study is to develop and validate an Immigrant Parental Stress Inventory (IPSI), that objectively and comprehensively assesses the stress experienced by immigrant parents within the Korean context. Based on the Immigrant Parental Stress Inventory developed within the American context, preliminary items were refined through a literature review and the discussions of experts and immigrant parents and were empirically validated with a sample of 203 immigrant parents residing in Korea. Through exploratory and confirmatory factor analysis, six main factors were identified (Factor1 Difficulties in communication, Factor2 Financial difficulties, Factor3 Difficulties in social adjustment, Factor4 Social discrimination, Factor5 Lack of social resources, Factor6 Difficulties in parenting). The IPSI was shown to be a psychometrically sound instrument that is capable of measuring immigrant parental stress within the Korean context. Social service professionals and researchers studying or working with immigrant families could use the IPSI to examine immigrant parental stress.

Smart power grid is a user friendly system that transforms the traditional electric grid to the one that operates in a co-operative and reliable manner. Demand Response (DR) is one of the important components of the smart grid. The DR programs enable the end user participation by which they can communicate with the electricity service provider and shape their daily energy consumption patterns and reduce their consumption costs. The increasing demands of electricity owing to growing population stresses the need for optimal usage of electricity and also to look out alternative and cheap renewable sources of electricity. The solar and wind energy are the promising sources of alternative energy at present because of renewable nature and low cost implementation. The proposed work models a smart home with renewable energy units. The random nature of the renewable sources like wind and solar energy brings an uncertainty to the model developed. A stochastic dual descent optimization method is used to bring optimality to the developed model. The proposed work is validated using the simulation results. From the results it is concluded that proposed work brings a balanced usage of the grid power and the renewable energy units. The work also optimizes the daily consumption pattern thereby reducing the consumption cost for the end users of electricity.

The purpose of this study was to investigate the social support, understanding of the children's problem in the female-headed single parents, and their child rearing methods. To obtain this purpose, in-depth interview was conducted to 8 female-headed single parents from March 3 to April 5, 2003. The contents of interviews were recorded and analyzed by qualitative method. The results were as follows: First, female-headed single parents were stuck for the social support and the relationships with parents-in-law were ruptured, especially. Secondly, female-headed single parents had well known about their children's daily life. Third, in the early stage of female-headed single parents, they had expressed the stresses in their hardship of life to their children, but it decreased whenever they were accustomed to their life.
