This study is on the spacial flexbility of house. In the recent days, it is true that the qualitative aspect of residence rather than the quantitative one has emphasized. But the inhabitants of residence undergo adaptation problems to deal with changing needs constantly. Residence must be the place to satisfy inhabitant's desire to live and dwell. According to changes in family life cylce and personal demand, the flexibility in housing should be beneficial. This study attempts to solve relationships of these need changes and inhabitant's adaptation through the spatial flexibility. Throughout the process of main discourse, some theoretical backgrounds of housing are applied. And to introduce the flexibility of residential space, concepts of flexibility according to 'time' and 'spatial structure' are employed. In addition to functionality and comfort, living should provide a touch of humanity attuned to individual sensibilities. The purpose of this study is to suggest a method can move interior structure by the flexible planning.

In the initial deployment stage of optical access networks, optical network systems and optical fiber cables have been provided mainly for commercial buildings or users in KT. According to the demand of residential users who expect to subscribe broadband multimedia services as high bit rate services, the optical access networks get closer to the residential users as FTTCab or FTTH So, it is very important to install optical access networks economically and effectively because that the total cost and usability of optical fiber cables depends on that. Especially, one of characteristics in access networks is the possibility of variation on services demands and technology evolution. Also access networks must be prepared for the final deployment, FTTH. Therefore, the designing and planning of optical access networks are coming to be very important activity for most of telecommunications service providers.

To cope with the serious housing shortage arising from rapid urbanization and industrialization, residential communities were constructed to meet the growing demand for housing. However, mass construction of these residential communities unavoidably resulted in uniformity standardization. In particular, for high rise apartment blocs using the ground floor as the center of the lower levels housings has raised problem of sunshine, airing, privacy. The research which it sees as the house low evaluation it is coming to become it plans a public facilities on lower levels of the building which keeps the quality which the ground connection and human scale back separates as, to solve the problem point of the lower levels house and the resident collective life which is smooth becomes accomplished.

The domestic construction industry is changing its preference for demand and supply along with urbanization and economic development. Accordingly, initial risk assessments is more important than before. Currently, the research related to risk analysis except for apartment studies is insufficient. Therefore, the objective is to suggest a basic study on financial analysis model development by applying optimization method in residential officetel. To achieve the objective. first, the previous studies are investigated. Second, the causal loop diagram is structured based on the collected data. Third, the financial model is developed by using optimization method. In the future, the proposed model can be helpful whether or not conduct execution of an officetel development project to the decision makers.

The effects of applying the micro CHP system to the domestic sector in Korea were investigated using annual cooling and heating demand data. Four prime movers, micro gas turbine, PEMFC, gas engine and Stirling engine, were compared for three operational modes. Two way buy-back was assumed for both electricity and heat. The Stirling engine gave the lowest $CO_2$ emission per energy for 300kWh monthly electricity production. However, PEMFC became more effective when considering PURPA criteria. PEMFC generated the least greenhouse gas with higher electrical efficiency for cooling. The Stirling engine, however, became competitive for heating with higher total efficiency.

The use of air-conditioning systems for cooling in residential buildings has negative effects on the environment and causes the problem in peak electric power demand in summer. The objective of this study is to demonstrate the potential of radiant cooling systems using ondol as an alternative cooling system in our residential buildings. Computer simulation has been performed for the floor radiant cooling system performance. The results of this study show that. 1) This system can control the temperature of Ondol room within comfort limits. 2) This system can be operated with a little risk of condensation but the control of latent heat will make this system more potential.

Recently, Smart Grid is a emerging topic in power and communication industry. Smart Grid refers to a evolution of the electricity supply infrastructure that monitors, protects, and intelligently optimize the operation of the interconnected elements including various type of generators, power grid, building/home automation system and end-use consumers. In order to successful implementation of Smart Grid, energy management function will be the key factor that coordinates and optimally controls the various loads according to the operating condition and environments, and the load patterns in residential and commercial building will be required as fundamental element for load management. In this study, we collects many types of energy usage data of electric appliances, analyze their load curves, and make the general load patterns for electrical appliance.

The purpose of this study is to actualize the planning method of the Mixed-use Housing. Enter in 2000 years, contruction of Mixed-use Housing is rapidly increasing with acrovill and tower palace as its starting point. Mixed-use Housing is topology that mix function of residential and business and commercial facilities by kind of mixed-use development. And, Mixed-use Housing which is located in busy urban commercial strict should meet the demand not only as functional city. And it is a type of urban housing that located in busy urban commercial district demands function of residential. As for locational situation and types of public space researched and analyzed in this thesis, those space were left alone with short analyzation on main consumers level as well as short recognition of public space for all of the six combined facilities of dewelling and commercing

The environmental pollution by noise is recognized by the pollution source made it not only to carry out harm of the Quality of a life of people seriously in most countries, but was generated for most actual problems. The measure to such environmental noise must conduct first investigation which noise generating currently regarded as questionable says in what grade has resulted and the suitable measure by that is studied. The concern of the residents who demand such a comfortable living environment is increasing rapidly. Therefore, the three areas of Jeollabuk-Do judged that noise is comparatively severe was selected. It is going to grasp delicately the noise actual condition of a residential, semi-residential, commercial, industrial area.

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.
