The purpose of this study was to regression analysis for variables on effect of development of scientific thinking. The subjects sampled in this study was 117 5th grade students, 131 8th grade students, and 127 11th grade students. The students were administered test of 10 questionnaires. The GALT(group assessment of logical thinking), FIT(figured intersection test), and GEFT(group embedded figural intersection test) were used which developed previous researchers. And other questionnaires were modified. The result of this study showed that cognitive variables, psychological variables, home variables and learning environment variables made effects on scientific thinking. Cognitive variables, psychological variables, home variables, and learning environment variables explained 60%, 10%, 5% and 10% to scientific thinking. All of those variables explained around 86%. Overall, 5th, 8th and 11th grade models were similar but with some differences in the effects of contextual variables with in the models.

The purpose of this study is to investigate (1) the level of childrens' concern and behavior on the environmental preservation, (2) the influential factors related to the two dependent variables above mentioned. The subjects were 286 childrens, in October, 1997, in kwangju. The data obtained were analyzed by Mean, Person's correlation, Stepwise Regression and Path Analysis. The major findings were as follows: 1) The general tendency of the childrens' concern and behavior on the environmental preservation was over the average level. 2) According to the background variables(ie: environment information contracting time, family cohesion and adaptability, biospheric orientation, egoistic orientation), the childrens' concern on the environment was significantly different. 3) According to (1) the background variables(ie: environment information contracting time, family cohesion and adaptability, concern on the environment, biospheric orientation), (2) intermediated variable(ie: concern on the environment), the childrnes' behavior on the environmental preservation was significantly different. 4) The indirect variable of the positive influence for childrnds' behavior on the environment, environment information contracting time. The indirect variable of the negative influence for childrens' the environmental behavior was egoistic orientation.

The purpose of this study was to analyze the monthly and seasonal PM10 data using the Autoregressive Error (ARE) model at the southern part of the Gyeonggi-Do, Pyeongtaek monitoring site in Korea. In the ARE model, six meteorological variables and four pollution variables are used as the explanatory variables. The six meteorological variables are daily maximum temperature, wind speed, amount of cloud, relative humidity, rainfall, and global radiation. The four air pollution variables are sulfur dioxide ($SO_2$), nitrogen dioxide ($NO_2$), carbon monoxide (CO), and ozone ($O_3$). The result shows that monthly ARE models explained about 17~49% of the PM10 concentration. However, the ARE model could be improved if we add the more explanatory variables in the model.

Purpose: This study was to identify the perceptions of nursing student on the clinical practice environment and related variables. Methods: The subjects of this study were 180 nursing students from a college participated in clinical practice at four regional hospitals. Data was collected with the questionnaire tool for the perceptions of clinical practice environment. Results: The students highly satisfied in the major had significantly high perception in innovation, personalization, student involvement, and clinical practice satisfaction. The students with a low level of stress and a clearly named guidance nurse were significantly high in the perceptions of task orientation, innovation, personalization, student involvement, and practice satisfaction. Clinical practice environment variables such as task orientation, innovation, individualization, personalization, student involvement, and practice satisfaction were significantly correlated with each other. In student characteristics, the main variables directly influencing the perceptions of clinical practice environment were religion, the level of stress, and the method of guidance. Conclusion: Understanding the students' perspective would be valuable for promoting a positive clinical practice environment. Developing a cooperative system between the college and educational hospitals is necessary for effective clinical practice education.

This study examined the characteristics of the relationship of home environment variables and preschool children's intelligence, learning readiness and socio-emotional developments. The subjects of this study were 63 children at age five and their mothers. Instruments included the children's intelligence test, preschool inventory for learning readiness, the socio-emtional rating scale and the inventory of HOME. The data of the present study were analyzed by the statistical methods of Pearson's product-moment correlation coefficient and step-wise multiple regression analysis. The kinds of HOME variables that significantly predict children's intelligence were "need gratification and avoidance of restriction" "quality of language environment" "play materials" "aspects of physical environment" "organization of stable and predictable environment". The variables that significantly predict children's socio-emotional developments were "breath of experience" "fostering maturity and independence" "developmental stimulation". All of the HOME variables were not significantly predict children's learning readiness. The kinds of HOME factors that significantly predict children's intelligence were factor II and factor III. Factor I predicted children's socio-emotional developments significantly. All of the HOME factors were not significantly predicted children's learning readiness.

This study is also to provide data for environment education. The subjects were 538 children, in June. 1998, in Kwangju. The data obtained were analyzed by Pearson's correlation. Cronbach's u coefficient. multiple regression. and Path analysis. The major findings were as follows : 1) The influential variables for childrens'egoistic value orientation were grade level of children and education level of mother The influential variables for childrens'altruistic orientation were the frequency of contact for environmental information and age of mother. The influential variables for childrens'biospheric orientation were education level of mother and the frequency of contact for environmental information. 2) The influential variables for the childrens'behavior on the environmental preservation were the frequency of contact for environmental information. biospheric orientation. grade level of children and education level of mother.
