Full-scale flexural testing of asymmetric H-shape hybrid composite beams was conducted in this study. In fabricating hybrid H-shape sections, high strength steels were utilized for the bottom flange while ordinary strength steels were used for the top flange and web. With adding a fully composite floor slab, a total of 8 hybrid composite beam specimens were tested. The primary objective was to develop the asymmetric hybrid H-shape composite beams with maximized flexural efficiency and investigate their flexural behavior. Not all the hybrid composite specimens tested in this study exhibited the plastic moment and reasonable deformability. In the specimens with high-strength bottom flange, the longitudinal shear crack of the slab along the beam axis often preceded the development of beam plastic moment, although the slab was designed as fully composite. The mechanical reason for this unexpected behavior is discussed. It is emphasized that the longitudinal shear strength of composite slab should be checked in designing hybrid composite beams utilizing high strength steels like in this study.

Recently old stone walls were designated as registered cultural properties that meant an extension of categories about cultural properties from a spot area to whole area. Moreover given the changing situation of residential pattern, which is due to rapid social change, this designation can be seen as a significant measure to keep as intact as possible traditional landscapes in agricultural and fishing villages. In this paper, I analyze the symbol system and meaning of old stone walls and attempt to pick out the cultural elements which are related to them. These days we have made efforts to various aspects for which make traditional cultural resources into cultural contents. But many studies had done before emphasized aspects for beauty only. Especially existing studies about an old stone wall was mainly focused on architectural interpretation and tourist route. So we need to build a plot around oral research and need a creative approach for sharing with tourists. Cultural contents combine the original form, potential and capabilities with media by detecting original form of culture and finding out the worth and meaning. In this paper examined the probability of using by investigating a stone wall in Sang-hak Village that is related with recovering of places to live in contemporary society and finding cultural contents. I suggest more creative ways to make cultural properties into tourist resources by considering the possibilities of place marketing using storytelling, based on an analysis of data gathered.

Various studies on program management have been attempted due to recent changes in the environment of the construction market, and the importance of closure phase in each phase of the construction program is increasing. However, the reality is that the related research is insufficient and the field has been managed in a rule of thumb according to individual capabilities. Therefore, in order to successfully close the construction program and enhance satisfaction of stakeholders in the closure phase of the construction program, the key stakeholders were identified using the Power and Interest Matrix. The relative importance of the closure phase process was analyzed using AHP analysis method. It was also verified through on-site surveys and interviews about the proposed importance of the closure stakeholder and the relative importance of the process. It is expected that this study will increase the satisfaction of stakeholders and contribute to a successful closure if the user puts a lot of resources into the process that has a high priority in the closure phase of the construction program proposed in this study.

Current changing to the customer-oriented market naturally causes suppliers to meet an age of competition on the quality. In order to plan housing meeting this quality competitiveness era, I set up the type classification system of quality differentiation for the unit of apartment housing by executing differentiation cases of unit quality and type analysis of the object. The system is consist of 3 classification systems by quality element, user convenience element and product element as follows: First element is to classify quality element on the basis of plane and interior elements, architectural elements and second one is user convenience element relating facility to classify environment-oriented, safety, energy saving and convenience. The other one is the product element to classify furniture, installing product and convenient product. I believe that this classification system will be useful to determine any classification elements of product for product positioning and product planning in the stage of marketing planning of apartment housing in the future.

Due to a significant decrease in the number of construction projects in the domestic market of Korea, overseas expansion of the Korean construction companies has been accelerated in recent years. However, the practice of bidding at a low price and lacking information about foreign new markets caused many companies to fail in their entries to these markets. As a measure to prevent such failures, this study has developed a framework which first defines the key research items that must be identified beforehand and then classifies them into a structured way so that the construction companies can actually use this framework to be better prepared for their forays into the new markets. The framework was actually applied for a construction project in Morocco, and its usefulness was proven by the user's successful participation into the project, nevertheless the application and result was limited. Although perhaps this framework should be applied to many more construction projects for its validity to be verified and for its structure to be better standardized, the framework still has its value due to the following two reasons: first, it has systemized the research items that had been only conceptually defined but had never been organized, and second it can be utilized as a investigation tool at the marketing stage.

To make provision for the super-aged society, the senior welfare facility which is a kind of typical physical environment of the nursing service would be expected to perform a very important role in local community. This study was conducted to identify the constructs of the servicescapes of senior welfare facility and to draw analysis indicators of it. For this, we performed literature review based on domestic & foreign government guide, service marketing theory and interior architectural results concerning the physical environment of the senior welfare facility. The result of this study showed as follows: servicescapes of the senior welfare facility could be explained as "a whole set of physical environment to support a variety of services provided by the senior welfare facility for the elderly or services of the kind of tangible clues". Analysis indicators of the senior welfare facility's servicescape could be explained as five factors: safety factor, functional factor, aesthetic factor, ambient factor and social factor. In addition we developed 37 pieces of detailed factors referred to five factors. The evaluation and verification of analysis indicators was carried out through 8 experts in-depth interviews. We inspected importance factor using a 5-point Likert scale, therefore safety factor was 4.41, functional factor was 4.27, aesthetic factor was 3.66, ambient factor was 4.20 and social factor was 4.25. More than anything else, in this study, there is a sense that it has established the concept of servicescape adapted to the senior welfare facility and contained a social element between the employees and the physical environment. Theoretical and practical implications of findings are discussed, and future research directions are proposed. we expect to be a little or benefits to the senior welfare facility corresponding to the future of the super-aged society.

Apartment developers consider the initial sales rate as an important indicator for their success of apartment development projects. They tried to achieve a secure level of initial sales rate. In spite of its importance, there is little research on the initial sales rate because of the difficulties in gathering proper data for analysis. This study, however, collects the data in initial sales rates in Su-won from various sources such as construction companies, marketing companies, sales companies and so on. By using this rare data, this study analyses the initial contract rate of apartment and estimates the initial contract rate by sales price. The result of this study shows that important of land area ratio, brand, and distance to park. It is expected that the proposed model will be used for apartment developers in sales planning phase.
