The purpose of this study is to examine the effect of contact with the elderly in a daily life on children's ageist attitude. Acknowledging the people's tendency to report in socially appropriate ways to the explicit attitude measurement, implicit measurement is introduced, and relation with the daily contact with elderly(DCE) is analyzed. The research question are as follows: 1) Are these two attitudes explained by different factors? 2) Can DCE alleviate both children's implicit and explicit ageist attitude? 3) How do the contact with grandparent and neighboring elderly affect the children's explicit and implicit ageist attitude? Data was collected from 503 fourth to sixth grade elementary school children. Child-Age Implict Association Test is used to measure implicit ageist attitude. Multinominal logistic analysis and ordered logistic analysis was applied. Followings are the main results: First, explicit and implicit ageist attitudes are found to be related with different predictors. Second, Elderly contact seems to lighten children's ageist attitude overall. Third, the effects of grandparental contact and the neighboring elderly contact on two different ageism were different. While the effect of elderly neighbor contact is limited to the expression of ageism, grandparental contact has a influence not only on the explicit but also on the implicit ageism, even though the effect on implicit attitude is limited in extent. Forth, not the quality of contact but the quantity of it was related to implicit ageist attitude. This result contradicts conventional idea of Intergroup Contact Theory. In the further research, the predictor of implicit ageist attitude need to be throughly examined.

In this study, using a complex of physical, chemical, and biological evaluation factors, the ecological vulnerability to climate change were evaluated at each river in the Nakdong river basin. First, runoff, sediment rate, and low flow discharge changes according to AIB climate change scenario using the SWAT model were simulated. Also, for the assessment of chemical and biological factors, 48 points that water quality monitoring sites and ecological health measurement points are matched with each other was selected. The water quality data of BOD and T-P and the biological data of IBI and KSI in each point were reflected in the assessment. Also, the future rise in water temperature of the rivers in Nakdong river basin was predicted, and the impact of water temperature rise on the fish habitat was evaluated. The top 10 most vulnerable points was presented through a summary of each evaluation factor. This study has a contribution to river restoration or management plan according to the characteristics of each river.

Two thematic maps on environmental geology were produced in the Cheong-Ju area, with aids of GIS technique. They are landslide hazards & risk maps and cut-fill maps. The models of environmental geology map and digital database were established for creation of these maps by means of cartographic simulation in GIS. These special maps are very important for understanding the environmental characteristics of the study area, and can be applied in the establishment of the regional land use planning. For instance, the landslide hazard and risk map can play very important role in the road design, and cut- fill map in the construction work in the area. The scoring system for landslide analysis was developed through the evaluation of each environmental geologic factor in relation to the others and reflects the relative imporatance of each factor. The excavation index(easy, intermediate and difficult) was evaluated through cut-fill analysis, and they can be very useftil for assessing the degree of excavation difficulty.

The purpose of this study is to estimate the direct and indirect effects of relevant variables on students' science achievements. Path analysis was conducted with data from middle school to examine the effects of perceived positive parenting attitudes, attitudes toward science, science inquiry skills on the science achievements of middle school students. A total of 502 middle school students from the metropolitan area participated in this study. Results suggest that students' perceptions of positive parenting attitudes had no direct influence on their science inquiry skills. However, the students' attitudes toward science and science inquiry skills were found to have meaningful direct effects on their achievements. Students' perception of positive parenting attitudes also presented a significant direct effect on their attitude toward science. In addition, the students' perceived positive parenting attitude revealed an indirect effect on science achievement, through their own attitudes toward science and science inquiry skills. Research findings called for more educational programs and teaching methods considering students' attitudes toward science and science inquiry skills to improve their science achievements. At home, parents need to have positive parenting attitudes to influence their children's attitudes regarding science.

This study proposed the information security integrated learning model-based KASP. By analyzing the teaching materials regarding information security in the regular curriculum, and by investigating preliminary studies, the information security contents were examined in terms of knowledge, attitudes, skills and ways to practice(KASP). And, the KASP-information security learning model integrating knowledge, attitudes, and ways to practice was developed, and the teaching plan and learning material hand-out were accordingly made out. Moreover, the developed model was tested in an experimental group, and common information security learning content centered on ethics in the comparison group in order to compare the results of two groups. As the test result analysis, it was verified that the developed KASP-information security integrated learning model was effective to help the students learn the knowledge, attitudes, skills and ways to practice.

Physicochemical characteristics of kochujang prepared with addition of garlic and onion, were investigated for 22 weeks of fermentation to obtain information on improving the quality of traditional kochujang. Moisture contents of kochujang increased during fermentation, but total nitrogen contents decreased slightly. The pH and titratable acidity of kochujang changed a little by addition of garlic or onion. Total sugar contents of kochujang decreased rapidly after 4 weeks, but reducing sugar contents increased until 2 weeks of fermentation. As the ratio of garlic increased, reducing sugar contents decreased. Ethanol contents increased during fermentation as mixing ratio of onion increased. Amino nitrogen contents of kochujang increased as mixing ratio of garlic or onion increased, but ammonia nitrogen contents decreased. Water activities of kochujang decreased slightly during fermentation, but consistency increased until 18 weeks. The color values of garlic or onion added kochujang were low in the L-values, but a- and b-values increased. Results of sensory evaluation showed garlic added$(2{\sim}4%)$ kochujang were more acceptable than onion added kochujang due to more favorable taste and flavor.

Radiation safety managements in medical institutions are needed to protect certain radiation damages as a part of National Coalition. This study investigates the characteristics of self-efficacy that become the major factor on the knowledge, attitude, and behavior on the radiation safety management of radiation workers as an approach of educational aspects and analyzes the relationship between such factors to provide basic materials for improving the activity level of radiation safety managements. In order to implement the goal or this study, a survey was performed for 1,200 workers who were engaged in radiation treatments in medical centers, such as general hospital, university hospital, private hospital, and public health center for 42 days from July 23,2006. Then, the results of the analysis can be summarized as follows: 1. Average scores on knowledge, attitude, and behavior in the radiation safety management were presented as $75.76{\pm}11.20$, $90.55{\pm}8.59$, $80.58{\pm}11.70$, respectively. Also, the average score of self-efficacy was recorded as $73.55{\pm}9.82$. 2. Knowledge levels in the radiation safety management showed significant differences according to the sex, age, marriage, education, and experience. Also, males of married, older, highly educated, and largely experienced represented high knowledge levels. Attitude levels in the radiation safety management showed certain significant differences according to the type of medical centers in which private hospitals showed a relatively low level compared to that of high levels in university hospitals. Behavior levels in the radiation safety management also represented significant differences according to the age, marriage, education, experience, and types of medical centers. Factors in married, general hospital, older, highly educated, and largely experienced showed high behavior levels. In addition, the self-efficacy showed certain differences according to the marriage and types of medical centers. Factors in married and general hospital demonstrated high self-efficacy levels. 3. Relationship between knowledge, attitude, behavior, and self-efficacy on the radiation safety management showed statistical differences according to the relationship between the knowledge and the attitude, the knowledge and the behavior, the attitude and the behavior, the attitude and the self-efficacy, and the behavior and the self-efficacy. The relationship between the behavior and the self-efficacy was represented as r = 0.482, which was the strongest relationship in such factors. Also, the knowledge and self-efficacy didn't show certain relationships.
