  • Recent mass construction of high-rise apartments across the country are questionable whether this housing type is appropriate for Korean families as one of housing alternatives. Therefore, cross-cultural analysis is needed for the evaluation of high-rise apartment living. The purpose of this study is to identify factors related to the evaluation of residential satisfaction, and to examine the differences of satisfaction between Korean and American high-rise resident groups on these factors and personal characteristics. The review of literature and factor analysis identified six important environmental factors. 413 subjects were selected from the major two resident groups in major U.S. cities, and Seoul, Korea. An examination by major factors indicated that five except for neighborhood environmental qualities were significant relationship. It was also found that personal characteristics of these two groups were significantly different. Multiple-regression analysis found that both physical quality of dwelling unit and management/maintenance were important predictors of residential satisfaction.

  • The precise prediction of reserved carrying capacity of bridge as a system is extremely difficult especially when the bridges are highly redundant and significantly deteriorated or damaged. This paper is intended to propose a new approach for the evaluation of reserved system carrying capacity of bridges in terms of equivalent system-strength, which may be defined as a bridge system-strength corresponding to the system reliability of the bridge. This can be derived from an inverse process based on the concept of FOSM form of system reliability index. It may be emphasized that this approach is very useful for the evaluation of the deterministic system redundancy and reserve strength which are measured in terms of either probabilistic system redundancy factor and reserve factor or deterministic system redundancy factor and reserve factor. The system reliability of bridges is formulated as a parallel-series model obtained from the FAM(Failure Mode Approach) based on the major failure mechanisms. AFOSM and IST methods are used for the reliability analysis of the proposed models. The proposed approach and method for the system redundancy and reserve safety/strength are applied to the safety assessment of actual RC and steel box-girder bridges. The results of the evaluation of reserved system safety or bridge system-strength in terms of the system redundancy and the system safety/strength are significantly different from those of element reliability-based or conventional methods.

  • This study is to analyze the satisfaction and the image evaluation of landscape elements in outdoor space by types of the university campus. The results are as follows. 1) Out of outdoor elements at university campus, planting area, resting area, access road, and water feature are recognized as major landscape elements. Among them, planting area and access roads are evaluated low in terms of satisfaction levels, therefore, improvement on these elements are required. 2) In outdoor space image evaluation, university campus has image such as 'simple', 'clear', and 'safe'. By scale of universities, both 'A' university, which is the biggest in terms of size of campus, and 'B' university, which has a medium sized campus, have a positive image. However, 'C' university, which is the smallest in terms of size of campus, has a passive and negative image. 3) 6 factors are extracted through Factor Analysis for image evaluation. All of the universities show positive image in the categories of 'clarity' and 'familiarity', however, 'B' university and 'C' university show negative image in the category of 'scale'. 4) In Correlation Analysis between landscape elements satisfaction level and image evaluation, it is showed that the group of landscape facility becomes a relation factor of overall image evaluation. As a result, the higher satisfaction level goes, the better image evaluation of overall outdoor space at university campus is.

  • The purpose of this study was to evaluate the visual effects and images according to changes in the silhouettes and length of miniskirt. The silhouettes of the miniskirt were classified into two different categories according to side line, H-line and A-line. We altered the length of the miniskirt in five categories with changes in 25cm, 27.5cm, 30cm, 32.5cm, and 35cm. For the visual evaluation, 10 stimuli were placed in mannequins, and were estimated by the experts in the fashion design. For the visual evaluation according to changes in the silhouettes and length of the miniskirt, we used 13 pairs of items to find the visual effects, and 23 pairs of adjectives to measure the visual images. The stimuli and adjectives were randomly given to the evaluators and were evaluated by the 7-Point Likert Type Scale. The data have analyzed by frequency, t-test, factor analysis, anova, scheffe's test and the MCA method. According to the factor analysis of the visual effects of the miniskirt, the result was classified into 3 factors: the thickness of the lower body, the length of the lower body, and the shape of the lower body. According to factor analysis of the visual image of the miniskirt, the result was classified into 4 factor: personality, attraction, elegance, and activity. The silhouettes of miniskirt had more positive visual effects and images in A-Line than in H-Line. Among the visual effects of miniskirts, the length affected the thickness and length of the lower body more than the silhouette did and, the silhouette had more effects on the shape of the lower body than the length did. And shorter the skirts, stronger the image of personality. However, 32.5cm and 35cm miniskirts are estimated to be more attractive than excessively short skirts. There are many differences in the image of personality and activity according to the changes in the length of miniskirts.

  • The purpose of this study is to find the bi-polar adjectives for rural stream landscape evaluation by the semantic differential scale and to suggest the major determinants of visual preference in rural stream landscapes. For this, the bi-polar adjectives for rural stream landscape evaluation was found by the method of the reliability test, and the spatial image was analyzed by the factor analysis. The level of visual preference was measured by slide simulation test, and these data were analyzed by the multiple regression. The major findings of this study can be summarized as follows : 1) Of the bi-polar adjectives expressing psychological and physical characteristics, the hi-polar adjectives which demonstrated reliability and consistency run as follows : Bi-polar adjectives expressing psychological characteristics : 'calm-bustling', 'unfamiliar-familiar', 'still-active','depressing-brisk', 'discomfortable-comfortable', 'suppressed-free', 'lifeless-living', 'quiet-noisy', 'unpleasant-pleasant'. Bi-polar adjectives expressing physical characteristics : 'artificial-natural', 'narrow-wide', 'rocky-not rocky', 'desolate-fertile', 'dirty-clean', 'enclosed-open', 'flat-steep', 'not gravelly-gravelly', 'thicketed-not thicketed', 'not weedy-weedy'. 2) Two factors, the harmony and the movement, were derived from the factor analysis for the psychological variables. Three factors, the naturalness, the rock, and the vegetation, were derived from the factor analysis for the physical variables. 3) Rural stream landscape types were classified into four types by the multi-dimensional scaling method. Type III, IV obtained higher rank of visual preference and type I, II obtained lower. 4) For all types, the factors determining the level of visual preference were found to be the harmony, the naturalness, and the vegetation. The visual preference determinants of rural stream landscape need to be considered in improving or restoring the rural stream landscapes.

  • In order to increase visitors' viewing satisfaction and viewing behavior in the art museum exhibit by flat works, it is necessary to analyze the characteristics of major evaluation factors, such as 'the number of artworks and their intervals', 'the space of exhibition and the size of walls', and 'compositional change of exhibition spaces', which have a close relationship with each evaluation factors, by focusing on artworks and exhibition space. Thus, to investigate how the characteristic differences of the major evaluation factors in art museums affect visitors' viewing satisfaction and viewing behavior, this study compared the related analytical indicators, and conducted a correlation analysis. The results of this study are summarized as follows: First, the degree of concentration on artworks (which has been selected as a collective assessment indicator of visitors' satisfaction) increased when the exhibition space of art museum is display by less artworks and they have big interval in the large wall. Second, visitors' viewing satisfaction and qualitative viewing behavior increased when the exhibition space of art museum are simple and they change to simpler step by step. These findings imply that there is a high correlation between visitors' visio-perceptual experiences and viewing behavior, and that visitors' viewing satisfaction and viewing behavior can be predicted partially in the certain exhibition environment from this correlation.

  • The purpose of this study is to construct the evaluation model for the major science research facilities and equipments to enhance the competitiveness of the science and technology and also to test the reliability and validity of the model. To achieve the purposes, this study theoretically reviews the concept of the major science research facilities and equipments and their characteristics. Through a review of literature, this study draws 11 criteria for evaluating the priorities of the major science research facilities and equipments. These criteria are categorized as two dimensions - 'science & technology' and 'national policy'. The dimension of science & technology includes scientific importance, technological readiness, utilization rate, common utilization rate, and ability of management and operation. The national policy dimension contains degree of correspondence with national science development, imperativeness of national policy, science and technical effectiveness, economic and industrial effectiveness, responsiveness of research demand, and equity among the related institutions. The competitiveness of the science and technology consists of these two dimensions. The evaluation model is established on the framework of criteria. The 18 major science research facilities and equipments are selected through a series of Delphi. The survey of experts (BT, ET, IT, NT and ST) is also implemented to evaluate the 18 major science research facilities and equipments by 11 criteria. The overall results indicate that the reliability and validity of the model are good. The reliability tests show that the five indicators of science & technology and the six indicators of national policy have high internal consistencies. The confirmatory factor analyses reveal that the two constructs - 'science & technology' and 'national policy' - have high convergent and discriminant validity. The correlational analyses also show that the criteria-related validity between them is high. Furthermore, the results of higher order factor analysis indicate that the fit indices of the model are high and suggest a good fit to the data. Based on these findings, the policy implications of the model are discussed.
