Recently there have been great interest in the street landscapes, and numerous studies have been investigating shaping processes of urban landscapes, legal systems for scenery management, landscape preference and evaluation techniques. However, there are only few studies investigating how planting types influence on street landscape evaluation and how the relationships among street landscapes are. This study aims to make a guidelines which can be used for securing afforestation in urban settings and improving urban environment. In specific, the results of this study can provide guidelines for urban street design and the base knowledge for identifying appropriate requirements for better street landscapes. We identify factors which make shape certain images of street landscape, and draw physical factors influencing on visual appropriateness through visual landscapes evaluation process. To evaluate landscapes according to planting types, on-the-spot survey at 14 streets in Gang-Nam district were made. The district is under executing street improving projects and shows the most satisfying planting types. To evaluate street landscapes which people experience during their walking, 100m of continuous streets are chosen. The survey sites exclude streets with irregular pattern, are adjacent to large urban parks or are used as parking spaces in part. We evaluated 9 street landscapes classified into 1-line-planting, 2-line-planting and 3-line-planting on the basis of the location of planting and the planting methods.

Behaviors of organizational members can be classified as two types. One is behavior required to perform formally given job. The other is a various kind of behavior taken voluntarily but not required directly and formally to perform job. The former can be called as in-job behavior while the latter can be called as extra-job behavior. Many organizational scientists so far, have focused on investigating in-job behavior. Yet, from a decade, organizational researchers have recognized that in-job behavior alone can not explain sufficiently job performance or organizational effectiveness Thus. they have paid attention to extra-job behavior, which is generally called as organizational citizenship behavior. Existing studies of organizational citizenship behavior have three types : First type is studying the concept and components of organizational citizenship behavior. Second tope is studying the determinants of organizational citizen-ship behavior and relationships with it. And third type is studying relatioships between organizational citizenship behavior and job performance. This study, therefore, have purposes as follows : Firstly, this study designs a comprehensive model in the below figure and generates inclusive hypotheses about relationships among antecedents, intermediate factors, and the components of organizational citizenship behavior. Secondly, this study investigating empirically such relationships and draws a picture of mediation roles of the intermediate variables. To design the model and generate the hypotheses, this study conducted a comprehensive literature survey on organizational citizenship behavior. To test the hypotheses, this study collected data from 847 employees at 12 large genral hospitals in Pusan area through a questionnaire survey and conducted the three step mediated regression analysis using the SAS-PC Package.

This Study aims at investigating actual condition on attending school road of children and analyzing empirically the characteristics of cognition and the influence of safety on school road. This study findings are as follows : 1) Walking alone to go to school is the highest rates among Commuting Mode, and Commuting distance to school is nearly doubles than range of school zone(300 m). 2) Among characteristics of urban spatial structure affecting on influence classify safety of school road, 'Commuting Distance' has been drawn to most influential variable. Especially, there are 4 types classified by commuting distance and it became obvious that the longer the distance, the lower the safety score(under 127 m=76.9 points, Over 451 m=58.3 points). 3) As a result of investigating the influence of Safety on attending school road, Vehicle commuting speed urder 127 m as internal of school zone, and Walking and crossing convenience over 451 m as external of school zone have a lot of influence on safety cognition on school road. Therefore Safety on school road should be considering the commuting distance to school among surrounding characteristics, needed for improvement plan and program based on real safety cognition of children.

Objective: The purpose of this study is to examine the test-retest reliability of paper-pencil test for investigating population stereotype of burner-control linkages of four-stove gas ranges. Background: Much of the research on gas-range stereotype strength has been performed using the paper-pencil test. While the use of the paper-pencil tests has the advantage of collecting data in a large group of subjects against reasonable costs, concerns regarding the reliability of the paper-pencil test has also been stated. Method: Three paper-pencil tests classified by intervals of test-retest were performed, in which eight types of burner-control arrangements were investigated. Sixty eight subjects were test-retested within two weeks, 85 subjects were test-retested within four weeks and 58 subjects were test-retested three times in series with interval of two and four weeks. Results: Chi-square test showed that three intervals of test-retest including two, four and two & four weeks have not statistically significant effect on subjects' responses irrespective of eight types of burner-control linkages dealt with in this study(p>0.10). Concordance rates of subjects' responses ranged between 73.5% and 100.0% for two-week test-retest, between 67.1% and 97.6% for four-week test-retest, and between 65.5% and 100.0% for two- and four-week serial test-retest. The concordance rates were linearly correlated with proportion of subjects' responses for stereotypes of burnercontrol linkages. Conclusion: It is concluded that the paper-pencil tests for investigating gas range relevant stereotypes could reproduce reliable results compared to baseline test within interval of four weeks. Application: The results of this study would be useful as an ergonomic guideline when designing the paper-pencil tests for stereotype relevant studies.
