노동집약적 현장중심의 습식공법의 한계로 인해 기술집약적이고 공장생산방식인 유닛 모듈러 공법이 주목을 받고 있다. 국내에서도 유닛 모듈러 공법을 개발하여 학교, 기숙사, 군막사 등에 활발히 적용하고 있으나 주거용 건축물에는 적용하지 못하고 있다. 그 이유는 거주성능에 대한 검증이 부족하고, 경제성에 대한 확신이 부족하기 때문이다. 따라서 본 연구는 모듈러 공법의 기술발전과 주거용 건축물로의 적용을 활성화하기 위해 모듈러 주택의 경제성을 분석하였다. 연구결과에 의하면 건설원가만을 단순 비교했을 때 모듈러 주택의 건설원가는 약 6.2% 상승하는 것으로 나타났다. 그러나 모듈러 주택의 장점인 공기단축이나 공장생산을 통한 생산성을 제고할 경우, 모듈러 주택의 건설원가는 벽식구조 주택과 비슷한 수준이 될 것으로 판단된다.

The number of modernized green houses have been increased to produce high quality and high-payoff farm products. The unit investment costs per pyeong($3.3058m^2$) for building a glass house was estimated at 449 thousand won. On the other hand, the unit prices for the PC house with iron frame and the vynil house with automatic control system were revealed 365 thousand won and 93 thousand won respectively. The main objective of the study was to identify the financial feasibility of the green house investment prevailed in rural area. At present, some farmers have selected the green house without any consideration of profitability of crops and accessiblity of their fanning practices and technology. For the soundness of green house cultivation and management, the indices of finacial efficiency for the modernized green houses were necessary. The decesion making criteria such as NPV(Net Present Value), IRR(Internal Rate of Return), B/C Ratio and Payback Period were analyzed for the individual high investment facilities considering the present farmer's technology and on-farm benefits and costs. The results of the feasibility analysis of green houses were as follows: 1. In case of 100% private burden of the investment costs, NPV revealed only positive value for the vinyl house with automatic system and IRR for the house was also estimated at more than 10% and B/C Ratio was amounted to more than 1.0. On the other hand, the other glass and PC houses showed negative NPV and unacceptable B/C ratio and IRR. 2. In case of the following terms and conditions as 50% Government subsidy, 20% loans and 30% farmers burden of the total investment cost, all the green houses showed acceptable IRR, B/C Ratio and NPV. 3. The financial feasibility of the glass house was acceptable in tomato cultivation rather than in cucumber cultivation. The payback periods of cucumber were represented as 8.9 years for glass house, 8.5 years for PC house and 4.1 years for vinyl house with automatic system respectively. In conclution, the glass and PC house cultivation of high value vegetables were only acceptable under the Goverment subsidy and loan systems from the view point of farmer's financial situations. On account of the unacceptable economic rate of return, the government subsidy and loan policy for glass house cultivation should be transfered to the vinyl and pc houses in the future.

The present study is a preliminary research improving the dwelling quality of apartment house as a kind of multi-family housing. The purpose of the study is to find out the actual state on characteristics of indoor noise including residents' living in apartment units. The method was field survey consisted of field measurements on equivalent noise level, observation on noise type, and interview on residents' responses. Field survey were carried out in 20 occupied apartment units from January to March 2007. The results are as follows. 1) Averages of indoor noise levels including residents' living noise were measured as $43.9{\sim}62.2\;dB(A)_{Leq5min}$, the average of each house except one was higher than the permissible level, 45 dB(A). 2) The noise types observed were mostly residents' living noise and classified into 'water hammer', 'living equipment noise', 'noise by family', 'hood noise', 'kitchen noise' in own unit, 'walking and talking noise in stairs and corridors', 'noise by neighborhood house', 'noise by the upper story' in building, and outdoor noise. 3) The residents showed slightly non-positive responses at 'noise by the upper story', 'noise by neighborhood house', 'water hammer', and 'noise by family'. Therefore, it is required to plan for preventing deterioration of the dwelling quality by residents' living noise in own unit as well as by neighborhood houses.

This study aims to analyze the current status and characteristics of apartment house unit plans towards spatial differentiation. The 172 house units from 32 housing complexes were selected for this analysis. In this study, factors of residential space plan especially in an apartment house are categorized into general characteristics on floor plan and factors for spatial floor plan. The Primary findings are as follows: (1) General characteristics on floor plan are analyzed based on space organization, area and number of bays. Among apartment houses over 40 pyeong, it seems that differentiation is well applied with various space plans available. (2) A result of an analysis on the factors for spatial floor plan shows that planning a living room with two-open-sides seems to be more common in the tower-shaped apartment blocks which are now on the increase. Moreover, many of them are adopting movable partitions to reflect resident's various demands on space plan. Among all, the extra kitchen in the balcony is planned high portion of 80.4%. And diningroom is positioned on the front side of the residential space along with a livingroom(19.2%). More frequently, dining area tends to face the living room(30.2%) according to the result. Besides dress rooms begin to be placed in each of the bedroom, once planned in one bedroom only while 18.6% of the apartment houses are placing new storages in the entrance to solve lack of storage space due to balcony extension.

Purpose: Now a day, Most of the residential house in Korea consists of apartment buildings. However, in the case of old apartment buildings, dwelling environment condition depends on management effort by residents. But we can't rebuild or restructure only old single dwelling unit in apartment buildings. And we can't move every single dwelling unit in the apartment building. Therefore, this study suggests a prototype of combinable container dwelling module apartment. Method: The method of research is exploring the case of previously constructed containers. Based on the case, This study suggests prototypes to create a variable apartment design with dwelling container units. Based on the prototype, various combinations are proposed to produce various types of dwelling space. Finally, this study makes an example plan for the apartment by using the container unit modules. Results: This study suggests combinable container apartment building prototypes. And it may be a fundamental study of changing the apartment building concept.
