In order to maintain the existence of a university in the era of infinite competition, it is actively promoting the establishment of a school dormitory, one of the welfare facilities, as a way to attract students who want to enter the university. In the past, university dormitories were built by the university and managed and operated on themselves, but recently, due to the poor financial situation of the university, university dormitories promoted BTL method that private construction company built dormitories and rented them for a certain period of time to manage and operate. J University has dormitories managed and operated by itself and dormitories managed and operated by entrusting the private sector. User satisfaction surveys are conducted on two dormitory facilities with different management and operation organizations, and the contents of the survey are compared and analyzed. This study is expected to be used as basic data when planning a dormitory remodeling project or a new dormitory establishment project in the future.

Consumers demand an increasing variety of requirements for the residential space as the quality of life improves. However, many apartment buildings with the bearing wall structure cannot meet such demands in Korea. A lot of construction resources are squandered and wastes are created as this type of residential buildings is reconstructed. The life of apartment buildings needs to be extended on the basis of easy remodeling of internal space in order to overcome the limits of the bearing wall structure. This research project aims to propose the Rahmen composite frame concept for the long life of apartment buildings. The Rahmen composite frame is expected to have better structural performance, constructability and economic feasibility than the bearing wall structure.

The Agricultural Land Remodeling Project was launched for agricultural fields with potential risk of flooding which were placed in low-lying area as a part of agricultural sectors of the National 4 River Project. It induced of the reclaimed agricultural fields on a national scale. The arable lands reestablished by reclamation have caused several big problems such as destruction of soil physicochemical properties, and thus the techniques to solve disadvantages were urgently required. In this study, we collected experimental samples from top soils in three agricultural areas, one from conventional agricultural fields (Hwasun, Jeollanam-do) and the others from reclaimed (remodelled) agricultural fields (Naju, Jeollanam-do and Gumi, Gyeongsangbuk-do), The soil chemistry data were analyzed using statistic tools such as semi-variance and kriging, and differences between natural and reconstructed soils were examined. The score, R (Ao) which indicates a dependence distance between each chemical element, was as follows; 21.8~43.5 (Conventional, Hwasoon), 4.4~70.6 (Remodelled, Naju) and 5.3~43.6 (Remodelled, Gumi). These results suggested that chemical properties of the reclaimed agricultural fields had a huge variation. Moreover, the result of kiriging maps also represented a ununiform pattern in the reclaimed lands. As a result of this study, it is strongly required to build up the soil type-specific management techniques for the reclaimed agricultural lands.

An oral environment is constantly exposed to environmental factors and microorganisms. The periodontal ligament (PDL) fibroblasts within this environment are subject to bacterial infection and allergic reaction. However, how these condition affect PDL fibroblasts has yet to be elucidated. PDL fibroblasts were isolated from healthy donors. We examined using reverse transcription-polymerase chain reaction and measuring the intracellular $Ca^{2+}$ concentration ($[Ca^{2+}]_i$). This study investigated the receptors activated by exogenous bacterial pathogens (Lipopolysaccharide and peptidoglycan) and allergens (German cockroach extract and house dust mite) as well as these pathogenic mediators-induced effects on the intracellular $Ca^{2+}$ signaling in human PDL fibroblasts. Moreover, we evaluated the expression of pro-inflammatory cytokines (interleukin (IL)-$1{\beta}$, IL-6, and IL-8) and bone remodeling mediators (receptor activator of NF-${\kappa}B$ ligand and osteoprotegerin) and intracellular $Ca^{2+}$-involved effect. Bacterial pathogens and allergic mediators induced increased expression of pro-inflammatory cytokines, and these results are dependent on intracellular $Ca^{2+}$. However, bacterial pathogens and allergic mediators did not lead to increased expression of bone remodeling mediators, except lipopolysaccharide-induced effect on receptor activator of NF-${\kappa}B$ ligand expression. These experiments provide evidence that a pathogens and allergens-induced increase in $[Ca^{2+}]_i$ affects the inflammatory response in human PDL fibroblasts.

In a large owner organization, a program manager of multiple maintenance and remodeling projects has experienced increasing scale and complexity of coordinating the M/R projects with in-house technicians who belong to multiple trade shops. This paper proposes a dual-level hierarchical planning strategy that consists of a program master plan in the long-term horizon and a master construction schedule in an operational scheduling window. A rolling horizon approach to the program master plan is proposed to deal with the external uncertainty of unknown stream of project requests. A resource-constrained scheduling algorithm is developed to generate the master construction schedule in a scheduling window. During development of the algorithm, more emphasis is placed on long-term organizational resource continuity, especially flow management of program constraint resources, than ephemeral events of an individual activity and project. Monte Carlo simulation experiments of three scheduling windows are used to evaluate the relative performance of the proposed scheduling algorithm against three popular scheduling heuristics for resource-constrained multiple projects.

This study was executed by means of "user participatory design method", as a part of the public facility remodelling project supervised by the Seoul Municipality. This study aimed to complement and improve the methodology through reviewing the whole process of participatory design implementation and examining closely whether the activities, design methods and tools that have been applied at each stage were helpful to reflect the users' demands successfully. Given all of those, it implies; first, it is very meaningful that public facility remodelling project by "user participatory design" leads the ordinary users to have direct opportunity to participate in the public business and to change their perception of the restroom environment in school. Second, it is necessary to integrate the roles of the facilitator and the architect from the beginning stage of the process, which makes it feasible to reflect the users' needs to the final stage. Third, it is required to modify the design tools that enable non-professional participants to understand their tasks and to perform them effectively at the stage of decision making.

Reconstruction and remodeling have been introduced as a part of renewal (redevelopment) projects for old apartments built after the mid-1970's and government policies for revitalizing each project has been changed continually. However, the frequent changes of the policies have caused conflicts among business entities in selecting business methods. The conflicts from their early stages have made serious problems in the entire business process. Therefore, this study deduced factors of business selection by applying comparison analysis between the two business projects on how certain factors have an influence on selecting reconstruction and remodeling business projects. Based on the analysis, four categories and 26 factors were finally selected. After then, the priority of each selection factor was deduced through the AHP method used for analysis of relative importance and impact values regarding to the business selection. It is expected to resolve conflicts among owners and select rational directions for reconstruction and remodeling business, based on the conclusion through analysis of influence on selection factors.

Living environments in rural area have become deteriorated rapidly. Increase of aging population, decline in agricultural income, polarization of wealth in rural community due to rural returners have caused severe decline and imbalance of living environments in rural area. Responding to this circumstances, governments currently develop projects for improving living environments focusing on individual housing which were excluded from governmental supports because those had been regarded as private property. Nevertheless, there are still some gaps and problems in evaluating the quality of living environment and suggesting effective solutions. It would be because standards and guidelines of the projects have been based on urban housing system. In order to support the implementation of the projects, this research has developed an index for evaluating and monitoring the quality of living environments in rural area. By applying Delphi method, the index has been created in four categories of 'security', 'convenience', 'comfortability', and 'durability' 'Security' consists of structural safety, crime, disaster, accident prevention. 'Convenience' includes three divisions of living, traffic, farm working. 'Comfortability' is divided into sanitation, indoor environments, and aesthetic appreciation. Lastly, 'durability' has four divisions of energy conservation, environmental friendliness, efficiency, and economics. Each sub-division also has different items from three to twelves. In the case of an index for performance evaluation, items have been derived from energy conservation(6-items), and environmental friendliness(7-items). Items developed as an index for evaluating rural living environments in this research might be good background information for remodeling project in rural housing development.

Recently our country need to change about hospital building operation and business change. The recent real estate development projects are made in very complex due to the diversity of development method or its legal aspects. Under such a real estate investment, the review of investment yield rate is fundamentally important for the one that invests and the one that finances it. Previously, the focus was in the review of the time to turn the surplus or the plan for making repayment of the borrowings, and without the analysis of sufficient investment yield rate. For a simple issue of finding the most advantageous project method, there is a need for reviewing the taxation issues, fund procurement method, legal aspects, policy analysis aspects and others. Therefore, the real estate investment is now likely to encounter the form of having the time of venture as well. In conclusion, the scientific and reasonable decision making in investing on the real estate does not suggest the absolute evaluation standard but the need and the use are more and more demanded.
