Differences in risk perception on major environmental issues between general public and environmental experts were investigated in this study. Questionnaire surveys were conducted to samples from general public and environmental experts during March and April, 2000. Total number of responses was 1,126 including 773 persons from general public and 353 experts. Risk perceptions on 26 environmental issues were related with the need to regulate each issue, controllability, experience, political views, interest in environmental problem, satisfaction of environment, severity of environmental pollution. There was statistically significant difference in risk perceptions between general public and experts. Overall, general public was likely to perceive risks associated with environmental problem, as well as social need to regulate these problems more than experts. The issues with high risk perception and need to regulate were 'automobile exhaust', 'industrial air pollution', ocean pollution by industrial waste and oil exhaust', 'air pollution by chemicals', 'surface water pollution by waste from household', 'industrial and hospital waste', 'surface water pollution by pesticide'and'sewage and food waste'. Consequently, it seems necessary to manage these issues, prior to others.

PBL can be defined as an active, self-directed and student-centered learning, and an opposite way of classroom teacher-centered learning which has been traditional role learning. PBL enables students think more efficiently and effectively when puzzling through the patient problems. The purpose of this study is to find out the perception of student nurse about PBL, the characteristics and the structure of the type for PBL. The research process is as follow : First, the researcher selected 35 statements for PBL with the content analysis of in depth interview and the literature review. Second, the researcher asks 38 student nurse to classify the statement cards. The result of the research is that the type of student nurse's PBL perception is divided into 4 types(Affirmative type, Negative type, Suspicious type, and Preferable type), and the explanative total variance is 44 percent. In relation to this, if PBL well combined and adapted in our traditional curriculum will change our nursing education in better direction.

To move in unknown or uncertain environment, a mobile robot must collect informations from various sensors and use it to construct a representation of the external world. Ultrasonic sensor can provide range data for this purpose in a simple cost-effective way. However conventional ultrasonic sensor system for a mobile robot are not sufficient for environment recognition because of their large beam opening angle, specular reflection. This paper describe on environmental perception algorithm which can solve these problems in case using ultrasonic sensor. The algorithm consist of two parts. One is to solve beam opening angle problem by fusion from multiple ultrasonic sensors. The other is to cope with specular reflection problem in wall line extract, which is based on Hough Transform. Experiments to verify the validity of the proposed algorithm are carried out, and the results are provided at last part in this paper.

The deteriorated apartments make a social problem in now a days. After all, a new alternative plan for deteriorated apartments such as the remodelling concept must be considered. This study aims to survey the perception levels among residents in deteriorated apartments relating to remodelling. It might be provide the basic data which could be used for the analysis of consumers in the future implementation of deteriorated remodelling projects. The analytical methods adopted in this study were factor analysis, 1-test, one-way ANOVA, post-hoc estimation(Scheffe test) by the SPSS 10.1 for Windows program. Through the factor analysis for the perception types regarding remodelling, the factors were named ‘function improvement orientation’ , ‘property value orientation’, ‘individual-household improvement orientation’, and ‘negative attitude to remodelling’. The analysis of the perception types regarding remodelling, by the family characteristics, socio-economic characteristics, residence characteristics, apartment block variables, resident's value orientation, and resident's satisfaction level, indicated that the perception degree of the ‘property value orientation’was the highest, followed by the ‘function improvement orientation’.

교통망에서 경로의 총 통행비용은 통행비용과 인지비용으로 구분된다. 출발지와 도착지간에 상이하게 인지되는 비용을 고려하여 경로를 탐색하는 것은 전체경로를 열거해야 하는 문제 때문에 현실 적용에 한계가 있다. 따라서 현재 활용되고 있는 첨단교통정보체계(ATIS)에서 경로정보를 제공할 때 통행비용 만을 고려하여 경로를 탐색하는 기법을 적용하는 것이 일반적이다. 본 연구는 경로열거문제 없이 상이한 링크인지비용을 반영하는 최적 및 K 경로탐색기법을 제안한다. 이를 위해 링크를 경로의 최소단위로 정의하고, 따라서 두 링크의 비교가 경로의 비교로 확대되는 링크표지기반경로탐색기법을 활용하며, 도착지를 기반으로 후방향 최적링크인지경로트리를 구축한 후 출발지기반으로 전방향 최적의 링크총비용 경로트리를 구축하는 수식과 알고리즘을 제안한다.

To investigate the risk perception of environmental issues, two consequtive surveys were conducted to environmental professionals using a standardized questionnaire from September to October in 1999. The number of subjects were 72 for the first survey and 68 for the second one. The questionnaire was consisted of items such as the degree of environmental pollution in Korea, risk perception of some issues on human health and ecosystem, and seriousness of the problems in the real situation in Korea. For the degree of environmental pollution in Korea, the average risk rating in the second test (7.4 point) was significantly higher than that in the first test (7.2 point). The risk perception on the general human health and ecosystem, and the seriousness in Korea situation were analyzed in the order of ′air pollution′, ′water pollution′,′soil contamination′,′waste′,′toxic chemical pollutants′,′food contamination′,′ocean contamination′, ′odor pollution′, and ′noise pollution′. Also ′toxic chemical pollutants′ problem was perceived to be the highest risk on general human health or ecosystem, and on present situation in Korea. ′Automotive vehicle exhaust′ problem was perceived to be the most severe environmental problems among specific 30 items. ′Industrial source air pollution′,′toxic air pollutants′, and ′domestic and industrial source pollutants to surface water′ were relatively severe environmental problems comparing to other problems. The pollution issues were classified into four categories by two aspects of perception; risk in general setting and seriousness in Korea situation. If the issues were highly serious in Korea and low risk perception in general setting then it is named "the Korea-specific group". Those that were all high score in two aspects, named "the Common group". Those that were all low in two aspects, named "the Nonsignificant group". And the issues were high risk perception in general setting and low seriousness in Korean situation, named "the Latent group".

Purpose: In this study, the fitness of a path model on suicidal ideation in university students was examined including the relationship of the following stress perception, problem focused coping style, dysfunctional impulsivity, somatization, anger, and depression. Methods: The subjects consisted of 645 university students. Data was collected using questionnaires and analyses was performed using SPSS/WIN 12.0 and LISREL 8.30. Results: According to the modified model, depression was found to have the most significant direct effect on suicidal ideation. Stress perception and problem focused coping style were also found to have a significant direct effect on suicidal ideation. On the other hand the anger, somatization, and dysfunctional impulsivity were found to have a significant indirect effect mediated by depression on suicidal ideation. Conclusion: These results suggest that university students' suicidal ideation can be decreased by managing stress perception, dysfunctional impulsivity, depression, anger, and somatization and increasing problem focused coping style. Based on the outcomes of this study, it is necessary to develop stress management methods and positive coping styles.

The purpose of this study was to identify the effect of experience emotion (i.e., happy, proud, sad, fear) on the risk perception. This study also examined interaction effects of emotion regulation (i.e., reappraisal strategy, problem focused strategy) between experience emotion and risk perception. The study collected data from 168 flight crew members in Korean commercial airlines, using an online research in which an experiment of emotion manipulation and a survey were included. The results of the study found the positive effect of happiness emotion on the risk perception regarding cases 1(these cases have high possibility of negative result and low circumstance control) and the positive effect of sadness emotion on the risk perception regarding cases 2(these cases have low possibility of negative result and high circumstance control). This study also found the interaction effect of reappraisal emotion regulation strategy between the relationship of happiness and risk perception regarding cases 2. From these results, the study provided that theoretical and practical implication that happiness and sadness emotion contribute risk perception and reappraisal strategy has a moderating role in the relationship between happy emotion and risk perception. Finally, based on these results, the limitations of this study and future research were discussed.
