Museum Architecture, passing through modem times, have been requested to make changes in order to respond to the necessities of current times as well, so that they come to develop various kinds of programs other than a mere exhibition. That is, museum began recognizing the diversity of activities available in the spaces and the openness to the public. And tried to keep up with the changes by linking the museum buildings with local community in urban architecture as a result. Conversion design is methodology aims at reforming old buildings into a museum or revitalizing buildings of historical significance into exhibition center, so that it made possible to utilize the texts of historical, cultural cities, which in turn contribute to the diversity of urban architecture and protection of buildings in environmental crisis. In the sense, the paper analyzes the life-long contribution and dedication of Carlo Scarpa, an Italian architect, in the conversion of museum architecture, and studies the style, techniques, and features witnessed from his architectural works, and finally offers an insight and a directing post to take advantage of diverse ways likely applicable in our urban architectures. Scarpa's features in his museum architecture are classified as follows: First, contrasting expression of reiteration and side by side to express the continuity of time Second, he conveyed implicated meanings through inserting contracted factors of the locality and traditionality. Third, his interest in formative works and handicraft had an influence on shaping conversion space Finally, expression of accidentally to change of a point of view.

The aim of this study is to provide foundational knowledge of how to enhance the user satisfaction of urban parks. The study seeks to identify essential factors that influence user satisfaction and to provide better design strategies for future park design as well as the reorganization of existing ones. To measure user satisfaction, this study used factor analysis to extract essential factors - facility conditions, landscape and scenery, safety, and kindness - by using data from a survey conducted by the city of Seoul in 2017. We then used a regression analysis to infer causal relationships between the independent variables and the dependent variables (user satisfaction). The results revealed that the most significantly and positively related variable to user satisfaction in urban parks was safety (${\beta}=0.276$, p<.000), followed by landscape and scenery (${\beta}=0.230$, p<.000), facility conditions (${\beta}=0.215$, p<.000), and kindness (${\beta}=0.208$, p<.000). The results indicate that, for future urban park designs, planners and designers should prioritize the issues of safety by adopting crime prevention through environmental design (CPTED). In addition, planners and designers of future park designs should heavily weigh the selection and provision of relevant facilities for the intended use as well as well-arranged and well-managed plants and trees. Based on the results of IPA analysis, the most urgent improvement elements appeared to be the factor of kindness; however, the impact of kindness influencing user satisfaction was less important than that of safety and landscape and scenery in the urban park design processes. This study demonstrates that to maximize the user satisfaction of the urban park design processes and to provide more valuable spaces for users, it is necessary to secure park safety and to create well-composed landscape and scenery. Future research should provide more detailed and specified urban park design strategies corresponding with the importance of the factors identified in this study.

Environmental design pattern of the nine Small Urban Spaces at C.B.D. in City of Seoul are surveyed and analyzed for user's satisfaction and behavior under the environmental design evaluation by using Christopher Alexander's Pattern Language. Small Urban Spaces as a part of streetscape are formed by physical factors as well as visual environment and interacting user's behavior. Therefore, user's satisfaction and behavior at the nine Urban Small Spaces were investigated under the further search for some possibilities of application of those Pattern Languages. A pattern language has a structure of a network. It is used in sequence, going through the patterns, moving always from large patterns to smaller, always from the ones which create comes simply from the observation that most of the wonderful places of the city were not blade by architects but by the people. It defines the limited number of arrangements of spaces that make sense in any given culture. And it actually gives us the power to generate these coherent arrangement of space. As a results, 'Plaza', 'Seats'and 'Aecessibility' related design Patterns are highly evaluated by Pattern Frequency, Pattern Interaction and their Composition ranks, thus reconfirm Whyte's Praise of urban Small Spaces in our inner city design environments. According to the multiple regression analysis of user's evaluation, the environmental functions related to the satisfaction were 'Plaza', 'Accessibility' and 'Paving'. According to the free response, user's prefer such visually pleasing environmental design object as 'Waterscape' and 'Setting'. In addition to, the basic needs in Urban Small Spaces are amenity facilities as bench, drinking water and shade for rest.

The double-peak normal distribution function (DPDF) suggested by Cho et al.(2004) has the problems that the extremely high and low tidal elevations are frequently generated in the Monte-Carlo simulation processes because the upper and lower limits of the DPDF are unbounded in spite of the excellent goodness-offit results. In this study, the modified DPDF is suggested by introducing the upper and lower value parameters and re-scale parameters in order to remove these problems. These new parameters of the DPDF are optimally estimated by the non-linear optimization problem solver using the Levenberg-Marquardt scheme. This modified DPDF can remove completely the unrealistically generated tidal levations and give a slightly better fit than the existing DRDF. Based on the DPDF's characteristic power, the over- and under estimation problems of the design factors are also automatically intercepted, too.

Purpose: This study explores the impact of discrimination experience on stress levels among Seoul's public housing complex residents, emphasizing the moderating role of social capital. Research design, data and methodology: Utilizing the 2019 Seoul public housing (PH) panel data and an ordered logit model, the research categorizes residents based on personal and environmental factors, contrasting them across different local housing price levels. Results: We find that public housing residents' experience of discrimination has a significant impact on stress, and local housing prices are positively related to stress. Interestingly, stress due to discrimination is more pronounced in high-priced neighborhoods, which are associated with real estate inequality. Conversely, this impact is less pronounced in lower-priced neighborhoods. Importantly, social capital not only has a significant moderating effect on stress for all residents, but in high-priced neighborhoods, it also moderates the stress caused by experiences of discrimination for social housing residents. Conclusions: These findings highlight the need for policy interventions to strengthen social capital and address socioeconomic disparities in public housing, and are significant for analyzing the nuanced relationship between neighborhood, housing affordability, discrimination, and stress in urban communities for public housing residents, which is a socially problematic issue.

For a coastal or harbor structure design, one of the most important environmental factors is the appropriate extreme highest tide level condition. Especially, the information of extreme highest tide level distribution is essential for reliability design. In this paper, 23 set of extreme highest tide level data obtained from National Oceanographic Research Institute(NORI) were analyzed for extreme highest tide levels. The probability distributions considered in this research were Generalized Extreme Value(GEV), Gumbel, and Weibull distribution. For each of these distributions, three parameter estimation methods, i.e. the method of moments, maximum likelihood and probability weighted moments, were applied. Chi-square and Kolmogorov-Smirnov goodness-offit tests were performed, and the assumed distribution was accepted at the confidence level 95%. Gumbel distribution which best fits to the 22 tidal station was selected as the most probable parent distribution, and optimally estimated parameters and extreme highest tide level with various return periods were presented. The extreme values of Incheon, Cheju, Yeosu, Pusan, and Mukho, which estimated by Shim et al.(1992) are lower than that of this result.

Buildings are responsible of major energy consumption globally. In addition, they are linked to thermal comfort. The need to provide comfort becomes more crucial in schools as they are the place where students learn, and develop their skills. This research aims to investigate the energy responsiveness of new and traditional school building design, where major variation in form, amount of external walls and glazing are different. The research focused on indoor microclimate condition of selected schools in the city of Jeddah where the climate is hot and humid using advanced tools for monitoring. The research uses advanced energy equipment to measure several aspects such as floor temperature, roof temperature, globe temperature and other factors which can lead to predictable thermal comfort of users. The findings suggest that a larger area of glazing shielded from sunlight has a greater influence on both indoor condition and general thermal sensation. The finding also suggests that the glazing ratio is a major contributor on indoor thermal pattern which can result in an increase in temperature profile between from $7-10^{\circ}C$. The findings of this research can assist in the improvement in the design of the prototype school building in hot and humid climate.

Evidence of liquefaction during the 2017 Pohang earthquake has highlighted the urgent need to evaluate the current seismic design standard for liquefaction in Korea, particularly the liquefaction triggering standard. With the simplified method, which is the most popular method for evaluating liquefaction triggering, the factor of safety for liquefaction triggering is calculated via the cyclic stress ratio (CSR) and the cyclic resistance ratio (CRR). The parameters in the CSR and CRR have undergone changes over time based on new research findings and lessons learned from liquefaction case-histories. Hence, the current design standard for liquefaction triggering evaluation in Korea should also reflect these changes to achieve seismic safety during future earthquakes. In this study, liquefaction susceptibility criteria were discussed initially and this was followed by a review of the current liquefaction triggering codes/guidelines in other countries and Korea. Next, the parameters associated with the CSR such as the maximum ground acceleration, stress reduction factor, magnitude scaling factor, and overburden correction factor were discussed in detail. Then, the evaluation of the CRR using the SPT N-value and CPT qc-value was elaborated along with overburden and clean-sand correction factors. Based on this review of liquefaction triggering evaluation standards, recommendations are made for improving the current seismic design standard related to liquefaction triggering in Korea.

The purpose of this study is to evaluate urban parks and green spaces within the public service framework by identifying priority elements. This study surveyed 455 residents from 80 dongs(neighborhoods), of 5 Gu(districts) districts in Daejeon. The results were as follows. Regarding the evaluation of urban parks as a public service, the average survey score, of all 46 questions, was distributed from 2.46 to 3.54(Likert 5 point scale). Interesting findings can be observed in that most of the survey participants gave high scores to Daejon's natural green environments and geographical traits. That is, Daejon residents perceived their urban nature spaces as a natural geographical environment rather than a public service provided by their local government. Therefore, it seems necessary for the local government, by and large, to improve urban parks and urban green space programs. The low scoring items were 'citizen's participation'(mean 2.46), 'acceptance of complaints, comments, and improvement proposals'(mean 2.54), 'citizen's respect', 'inclusive design' (for the physically challenged-mean 2.55), 'diverse programs and activities in the urban park'(mean 2.55) and 'implementation of revision proposals by citizens'(mean 2.61). These results indicate that citizen participation in planning and opinion sharing is needed to build public services that are satisfactory to users. To evaluate the park and green space from the viewpoint of public services is a useful method with a new point of view. In accordance with this study, the factor of 'supply decision maker' is a statistically meaningful variable of resident satisfaction while earlier studies on the satisfaction studies of physical environment, hardly discovered variables on 'supply decision maker', 'acceptance of resident opinions', and 'information usage'. Responding to or taking positive action according to significant factors, such as the findings of this study, can expand the role of public officials to exert a more positive influence on urban parks and green spaces.
