Architectural research, volume 5, issue 1, 2003, Pages 1~8
personalization reflects some aspects of the residents’ past experience in housing environment. For this purpose, this study aims to explore the range of personalization in living environment through a cross-cultural investigation. With regard to the different cultural backgrounds, the examination is illuminating a way of knowing how people think and feel about the current living spaces and how they control and influence the environment with activities as well as personal expressions. The study found the effect of childhood emotional experience by environmental auto-biography appears to be statistically significant on the personalization of their current living space. However, survey groups (Korean vs. American students) are likely to have varying degree of emotional levels and therefore, provide different predictors for personalization of space, which means culturally different facilitation of living spaces depending upon their past experience. Regarding the perception of childhood emotional experience, t-test showed statistically significant differences. Factor analysis identified three major components which influence the personalization of space; maintenances, decoration, and attachment to living space. Chi-square test revealed that American students tended to record more intensive levels of the personalization factor. Moreover, stepwise regression analysis also indicated that cultural groups are different in predicting the level of personalization on their current living space. Finally, the investigation of graphs indicates different patterns of personalization on each type of emotional experience. From another standpoint, the research implies that childhood experience functions as an important determinant of a person’s emotional experience with residential environments, and therefore, has a significant impact on the personalization of their current living space.

Oh, Se-Kyung ;
Architectural research, volume 5, issue 1, 2003, Pages 9~19
The major objective of this research is to study the relationship between apartment housings unit and resident satisfaction in the Seoul metropolitan area. To achieve this objective, the study were employed to survey resident satisfaction with various apartment housings and then, to discover the important factors affecting resident satisfaction with apartment housing unit by using statistical analyses. This study found that that most personal and physical variables studied are not significantly related to the level of satisfaction with apartment housing unit. Among those variables, dwelling unit type, building siting, and income are significantly related to their satisfaction. However, these objective variables are somewhat weaker predictors of satisfaction compared to other significant subjective evaluation variables. Dwelling unit type appears to be related only to satisfaction with the medium unit. Among subjective variables, the evaluation of Anbang, bathroom and utility room size was found to have a very important influence on satisfaction in the small unit; the evaluation of living room and dining space size together with dwelling unit type in a medium unit; the evaluation of the living room location, dining space size, and utility room size in the large unit.
Effects of Perceived Safe Environment on Social Interaction among Neighbors in the Public Outdoor Space of High-rise Apartment Housing
Kim, Won-Pil ;
Architectural research, volume 5, issue 1, 2003, Pages 21~28
High-rise housing are often associated with high-density that makes people's relationships superficial, specialized, instrumental and impersonal. Many design professionals have advocated the importance of socializing between human beings as a means to cultivate neighborliness but have not explored any substantial spaces embodied in a highly isolated dwelling unit of high-rise housing. Previous studies found evidences that increased level of social interaction is fostering more feeling of being safe. However, it is not well-known whether increased feeling of safe and secured environment brings more frequent neighboring or social activities to high-rise residents. For that purpose, this research intended to investigate the interrelationship between these two concepts. A linear regression analysis found that the effects of feeling safety and securities do appear to be very great on the facilitation of socializing between neighbor residents. From another standpoint, the study suggested that public spaces should be carefully located and designed to promote social activities by providing such intermediate devices as sports facilities, play ground, and rest place for residents.
Contribution of Horizontal Louvers to the Daylight Distribution in a Large Multipurpose Hall
Kim, Soo-Young ;
Architectural research, volume 5, issue 1, 2003, Pages 29~36
Daylight distribution in a large multi-purpose hall with complex geometry was analyzed using computer simulations under a limited number of daylight conditions. Daylight conditions included clear glazing with no louvers, horizontal louvers, and louvers positioned at a
under a clear sky at 10:00 AM of the day and year. Average daylight illuminance on each indoor surface was determined for given daylight conditions. Illuminance levels on surfaces were impacted critically by the louver conditions. The daylight illuminance on floor changed significantly as the calculation point moved back from the east-facing window. The contribution of louvers to the daylight distribution was provided. The louvers reduced the daylight up to 44.93% as compared with that of the no louver condition. The correlation between the illuminance on eastside window surface and on indoor floor was calculated using linear regression in order to predict impact of louver to floor illuminance. The
values ranged from 0.6066 to 0.9230 according to louver angle. The daylight distribution by ray diagrams and a computer rendering image were presented to show how each surface was impacted by the daylight according to different louver conditions under different season.
A Multi-attribute Decision Model to Measure Preliminary Feasibility of the Privatized Building Projects
Ock, Jong-Ho ;
Architectural research, volume 5, issue 1, 2003, Pages 37~47
The Build-Operate-Transfer (BOT) mechanism is extensively used worldwide to promote diverse building projects. Success in the BOT projects mainly depends on choosing a right project to propose. However, it is very difficult to identify a preliminary feasible one at the up-front project development process due to the uncertainties involved. When choosing a probable project to propose, the developers in most cases rely on their experience, intuition, or gut feelings. It is expected that they will improve the chances of deciding a viable project to propose if the methodical formalism is provided that guides to systematically recognize the risk factors inherent in the project environment, their impact on project feasibility, and strategic alternatives to enhance them. The main objective of this research is to develop a go/no-go decision model as the formalism. Based on the review of diverse decision-making theories, the Multi Attribute Decision Analysis Method (MADAM) is identified as a suitable theoretical methodology to developing the formalism. Fourteen BOT experts are invited to put their experience in the model development. A numerical example is presented to demonstrate the computational procedures of the model developed.

The purpose of this study was to find the senior housing alternative in Korean situation from the model of sheltered house in the U.K. and service house in Sweden, based on the empirical study of Korean. Research methods used in this study were documentary study and social survey research using the questionnaire. Research subjects were limited to the middle-aged group in their 50’s (from 50 to 59 years old), living in Seoul metropolitan areas. Survey data was collected from November 2, 2002 to November 23, 2002. This research found 123 subjects from 556 samples who responded were willing to move into senior congregate housing Most of them were not college graduate and made a monthly income ranged from $1667 to $3333, which average of monthly income is $3293. Most of them had their property less than $0.25 million and their average assets were $0.445 million. The ‘total assets’ were proved to be the only variable factor through the multiple regression methods that has an influence on the intention to move into senior congregate housing They preferred the single-detached house when they were being healthy but they preferred the apartment type when they were not being healthy or being alone. And they far preferred the home ownership. With respect to the location of senior congregate housing, while suburban areas were preferred when not being healthy, the downtown area was preferred when being healthy and be widowed. Based on such result, it could be suggested as follows. Firstly, the housing model eligible for government support for the aged society, it is recommended the model ‘category 2 sheltered housing’ by the public sectors in the U.K. However, it is necessary that the service may be applicable to ‘category 2.5. sheltered housing’. Secondly, The desirous number of units seems to be less than 20, which are coupled with the construction rules for its own sales business in Korea. Thirdly, in designing senior congregate housing, it must be supplemented in construction regulation as a universal design or lifetime home.

Data warehouse technology can be applied to the construction industry. Also, compared with William Inmon's criteria, we suggest that the principles and strategies for applying data warehouse technology to the construction industry through requirement analysis and modeling the business requirement (assumed as ‘main concern’) of the stakeholders in construction project. This technology can strengthen the competitiveness of the construction industry in the struggle environment for survival nowadays, enhance profitability and promote its valueadded. Although data warehouse technology is quite a new concept for construction industry, it has been prevalent in other industries since late 1990s, including the financial industry, manufacturing industry and other service industries. We found out that profitability and value-added in construction industry is closely related to contractors, who are suggested as the end user of the construction data warehouse that we propose. At the conclusion, we suggest ten principles and strategies for applying data warehouse technology to the construction industry, including the system architecture of the construction data warehouse.

Architectural research, volume 5, issue 1, 2003, Pages 69~76
This paper presents 3D workspace modeling to use for heavy equipment operation on construction sites. Construction environment severely prohibit operator to drive heavy equipment safely. According to the Occupational Safety and Health Administration (OSHA), a significant percentage of all fatalities in the construction industry stem from incidents involving the operation of heavy equipment (OSHA, 1990). Simulation based on 3D graphical modeling may assist operator to avoid this incidents on construction sites. Also, 3D graphical modeling is required for real time application such as equipment control as well as as-built data acquisition. However, current 3D graphical modeling has limitations including time consuming process, high systems required and labor intensive. This paper proposes rapid and efficient workspace modeling method by using sparse cloud points. It may takes 5-6 minutes to develop 3D modeling but traditional 3D CAD system took several hours or even days. Proposed modeling methods are successfully tested on construction sites. It is concluded that proposed research will contribute the realization of construction automation in the construction industry.

Jang, Hyoun-Seung ;
Architectural research, volume 5, issue 1, 2003, Pages 77~83
The construction material allocation method provides a logical order and priority for space planning decisions with reasonable costs. Genetic Algorithm (GA) modeling assumptions are made in order to properly allocate space for construction materials after super structure work. It will result in lower computational costs and increase in productivity. A Java program was developed to experiment and implement the Genetic Algorithm (GA) system. Computational result from a case of GA is presented. There was significantly different objective for a case that was applied on the actual ongoing building that is located in a high-density area. The model improved 14% in the total distance between working space and materials.
