Purpose - This purpose of this research is to verify the influence of the care workers' environment on their job satisfaction and on their voluntary behavior. Research design, data, and methodology - Data were collected from care workers at elderly medical and home care facilities in Korea in Seoul and Kyung-ki. Of 367 total respondents, 285 responses were used. This study performed exploratory factor analysis in order to verify the validity and credibility of the data. Regression analysis was conducted to verify the influence of the working environment, which encompasses the worker's relationship with the agency and with the elderly, on job satisfaction. Results - The hypothesis results were: First, from analyzing the influence of the working environment on the worker's job satisfaction, both relationship with the agency (p<.001) and relationship with the elderly (p<.05) positively affect job satisfaction; second, the exploratory analysis verifies the influence or the working environment on job satisfaction. Conclusions - The results indicate that the relationship with the agency (p<.001) and relationship with the elderly (p<.001) both positively affect the voluntary behavior of the workers.

From the perspective of employees working for public service agencies, we analyzed the causal relationship between service quality, relationship quality, design quality, customer satisfaction, and trust in public services. We conduct statistical analyses on the quality attributes we derived from a critical incident technique(CIT) analysis and build a measurement model, which has a second-order hierarchical structure. Survey data was collected from social work, childcare, and healthcare services. Using a structural equation modeling method, we identify a causal model and simultaneously estimate factor loadings and path coefficients. We find that all the quality dimensions are antecedents to satisfaction and then satisfaction precedes trust. The results show that service quality and design quality mediate in parallel the effect of relationship quality on satisfaction and both relationship and design qualities have stronger effects on satisfaction rather than service quality.

The objective of this study ware to explore the antecedent and consequences of management quality and to examine the mediating effects of the management quality on the relationship between antecedent and consequences. In order to verify the relationships and mediating effect, data were obtained from 328 employees working in firms at Jinju, Masan, Changwon City were analyzed by using SPSS 12.0. and AMOS 5.0. The findings are as follows: First, antecedent(psychological ownership) was positively related to management quality. Second, there were also positive relationship between management quality and consequences(employee's attitude). Third, there were also positive relationship between psychological ownership and employee's attitude(job satisfaction, organizational commitment). Finally, management quality was a partial mediating effect on the relationship between psychological ownership and employee's attitude. Based on these findings, the theoretical and practical implications and limitations are discussed in conclusion.

This paper describes an adaptive quadtree-based 2DH wave-current interaction model which is able to predict wave breaking, shoaling, refraction, diffraction, wave-current interaction, set-up and set-down, mixing processes (turbulent diffusion), bottom frictional effects, and movement of the land-water interface at the shoreline. The wave period-and depth-averaged governing equations are discretised explictly by means of an Adams-Bashforth second-order finite difference technaique on adaptive hierarchical staggered quadtree grids. Grid adaptation is achieved through seeding points distributed according to flow criteria(e.g. local current gradients). Results are presented for nearshore circulation at a sinusoidal beach. Enrichment permits refined modelling of important localised flow features.

The purpose of this study was to investigate the effect of science journal writing on science-related attitude and science academic achievement of elementary school students in order to find out the value of science journal writing. For this purpose, one class of 6th graders was tested. The result of this study were as follows: First, Science journal are classfied by forms and content. The most frequently used types are prose and organizing concept. Second, Science journal writing brought positive effects on science - related attitude, especially cognition of science. Third, Science journal writing has positive effect on science academic achievement. Therefore Science Journal Writing can be useful method in Science education.

This paper presents a hybrid method for recognizing the faces by using principal component analysis(PCA) and fixed-point independent component analysis(FP-ICA). PCA is used to whiten the data, which reduces the effects of second-order statistics to the nonlinearities. FP-ICA is applied to extract the statistically independent features of face image. The proposed method has been applied to the problems for recognizing the 20 face images(10 persons * 2 scenes) of 324*243 pixels from Yale face database. The 3 distances such as city-block, Euclidean, negative angle are used as measures when match the probe images to the nearest gallery images. The experimental results show that the proposed method has a superior recognition performances(speed, rate). The negative angle has been relatively achieved more an accurate similarity than city-block or Euclidean.

The purpose of this study is to investigate the perception of quality property of hospital information system, the quality level, and its effects. The participants were 730 employees who are using hospital information system in hospitals. In order to analyze the relationship, the quality property regulates the consideration of user's taste and the state of user's favor for the design of hospital information system, and the quality level regulates user's convenience and properness. The main results from this study can be summarized as follows, First, the perception of quality property for hospital information system showed few significance level between occupation, but revealed significance level between position. The evaluation of quality level showed significance level depending on the occupation and position. Second, quality property which generally affects to the quality level of the hospital information system were different between types of occupation and quality factor.

The catalytic effects of carboxylic acid and dibutyltin dilaurate(DBTL) on the curing rate of acrylic polyol with isocyanate prepolymer were investigated. In this work reaction of a biuret type aliphatic isocyanate with acrylic polyol follows the second order reaction in the thin film state. Carboxylic acid of acrylic polyol has a strong catalytic effect on the isocyanate groups and influences greatly on curing rate, also DBTL is more effective catalysis on acrylic polyol without carboxylic acid than with carboxylic acid.

To extract apple pectins, apple pomace (AP) was extruded under 14 different conditions of screw speed (250-350 rpm), feed rate of 30-40 kg/hr, and 20-30% moisture content using twin-screw extrusion. Response surface methodology (RSM), based on three variables by three-level factorial design, was employed to investigate effects of screw speed, feed rate, and moisture on dependent variables of extrudates, soluble dietary fiber (SDF), yield of anhydrogalacturonic acid ($Y_{AGA}$) representing pectin, and intrinsic viscosity ([${\eta}$]). Second order models were used to generate three-dimensional response surface for dependent variables, and their coefficients of determination ($R^2$) ranged from 0.96 to 0.99. Moisture content showed highest effect on solubilization of AP.

The purpose of the study was to review literature on universal and residual services of early family-intervention. The review was focused on early family-intervention cases proven effective in empowering children, parents and families, which, in turn, brought about positive synergy effects to the community at large. Literature review was presented in the following order: first, the universal needs for early family-intervention; second, critical components and strategies of early family-intervention for successful outcomes; third, on-going international projects of early family-intervention, both universal and residual services, proven effective on a long-term basis. In conclusion, findings of the study were summarized and the theoretical, practical and political implications for Korean society were further discussed.
