Objectives : The purpose of this study was to evaluate the reliability of questionnaire according to item arrangement on patient satisfaction questionnaire. Methods : We developed the two types of questionnaire with different item arrangement. In the first type (A), questions were arranged according to medical service dimensions. Questions in the second type (B) were arranged according to medical process. Both questionnaires were composed of six dimensions: physical environments, process, competence, courtesy, information giving, understanding patients. Measurements were performed on a 5-score Likert scale. In an outpatients and inpatient survey, total 777 patients answered the type A (outpatients: 257, inpatients: 128) or Type B (outpatients: 257, inpatients: 135). In order to compare the internal consistency of two types. Cronbach's ${\alpha}$ were calculated. Multiple regression analysis was also performed to know which type of questionnaire explain more of the overall satisfaction. Results : In outpatient survey, type A questionnaire showed higher internal consistency than B except physical environments dimension. Also in inpatient survey, type A had higer internal consistency than B in four dimensions(process, competence, courtesy, understanding patients). In the results of multiple regression analysis, type A questionnaire ($R^2$=0.53) explained more of the variation in overall satisfaction then B questionnaire ($R^2$=0.43) in outpatient survey. In inpatient survey, type B questionnaire ($R^2$=0.40) explained, more of the variation in overall satisfaction than type A questionnaire ($R^2$=0.33).But the difference of R was not significant in inpatient survey. Conclusion : The results of this study support that type A questionnaire has higer reliability in assessment of consumer satisfaction than type B.

PURPOSES : This study is to suggest suitable lighting facility installation plans by finding out driver's preference for combination of lighting facility installation among landscape factors that affect driver visibility in tunnels. METHODS : SD method is used to extract emotional factors that affect drivers' preference, Components of tunnel lighting facility installation are evaluated through conjoint analysis and it suggested relative importance of attributes and utility values. RESULTS : In the aspects of satisfaction levels of components of tunnel lighting facility installation, Tunnel side, two lows, and solid line arrangement type has the highest level of satisfaction. Extract emotional factors that affect drivers' preference are "safety", "openness" and "amenity." In addition, the result of analyzing relative importance of attributes of tunnel lighting facility shows that numbers of lighting array has the highest importance and lighting facility arrangement has the lowest importance. Result of analyzing partial utility shows that the 2 low type among number of lows, the solid line arrangement type between arrangement types, placing in the middle part among lighting facility arrangement were highly preferred. CONCLUSIONS : In the case of lighting numbers, utility values of the first line and the second line showed us a big difference. Increasing the number arrays in the future reformation of lighting facility installation combination will be effective in enhancing the utility of the driver.

The readability and the visuability are very significant when the letters or figures are displayed as static visual information. Not only is the beauty of the body type character(small letters) important but the display type character(large letters) should also be read easily, quickly and precisely. The issue regarding the readability in terms of perception of information has been raised continuously for all kinds of small signage and billboard, etc., which are written in display type within our everyday life. Among the various kinds of small signage and billboards the car licence plate is well known. Among all the possible factors that would have made an impact on the readability of licence plate, this paper focused on the effects of arrangement of character(letters and figures) and contrast of colors for the readability of licence plate using the within-subject analysis. The statistical analysis results in error reading rate, the character arrangement were significant but the color contrast(green/white, white/green, blue/white, white/blue, black/yellow) was not, No interaction was found.

The horizontal thermal storage tank with heat pipe which is suitable for the sensible heat storage system is able to store a hot water from the heat source such as heating pad efficiently and to supply a hot water to load rapidly. Therefore Arrangement of heating pad affects thermal flow and thermal storage efficiency. So, if effective arrangement is decided for condition of constant number of heating pad, the more rapid thermal flow effect and higher thermal storage efficiency is obtainable by active heat transfer. In this experiments, number of heating pad is ranged from three, five and nine, and when number of heating pad is constant, arrangement are two types of concentration-type and dispersion-type. As a result, for the case of concentration-type of heating pad, strong entrainment take place in horizontal thermal storage tank with heat pipe by active heat transfer and in the constant number of heating pad, the concentration-type has the higher efficiency with about 5∼6% than the dispersion-type. Therefore, when heating pad is equipted to horizontal thermal storage tank with heat pipe, concentration-type of heating pad is an efficient design in constant number. of heating pad.
