The purpose of this research lays on examining the adequacy of the hybrid ventilation system. The hybrid ventilation system must satisfy the next to be used. Firstly, the cold-draft phenomenon must not exist in the occupied zone. Secondly, the condensation must not happen on the surfaces of vents. Thirdly, the flow of make-up air must be happened in an each space by exhausted air of a rest room and living room. We used an examination and CFD method to verify these. Trough the examination of air-vents, We confirmed that the cold-draft to be induced by make-up air does not happen and could not find the condensation in the limits of outdoor temperature higher than 265K. Through CFD simulation, We confirmed that the rapid temperature change existed only within 0.5m the occupied zone and the flow of air was happened in an each space by only exhausted air in the rest room and living room. Consequently, the hybrid system is possible method to an apartment house.

By 2019, Korea is expected to be an aged society, age group of 65 and older being over $14\%$ of the total population, considering their rapid increase today. Also the phenomenon of population structure are accelerated by a low birth rate and long life span. This study was intended to find out the inconvenient details in houses pointed out by the elderly. This survey was taken by trained interviewers from the people of ages 65 and older living in Daejeon city. Statistical analysis was implemented from 583 appropriate data out of 624 questionnaires using (SPSS PC+ 10.0). The results were as follows. The elderly were put to inconvenience noises in room, old facility in living room and outmoded facility in kitchen and bathroom in detached house. And they were put to inconvenience the size of room, living room and bathroom and old-fashioned facility in kitchen in apartment. The stairway and bathroom in detached house and balcony, elevator and bathroom in apartment were pointed out dangerous spaces in house.

The purpose of this study was to make clear the indoor environmental efficiency of front balcony 'in apartment houses during winter. The field measurements of indoor environmental elements were carried out at an ordinary house with an existing front balcony and a house renovated the front balcony into the living room. The measurements in two-subject houses were taken on simultaneously the 20$^{th}$ ${\sim}$ 21$^{th}$ of January 2003. As results, the averages indoor temperature in the ordinary house and the renovated house were same as 23.6${\circ}$C, and the averages globe temperature in two houses were same as 23.7${\circ}$C. But, estimated heating time of the renovated house was longer than that of the ordinary house. The daily ranges of indoor temperature and globe temperature in the renovated house were wider than the ordinary house. The daily ranges of indoor temperature and globe temperature in the renovated house was longer than that of the ordinary house. The uniformity ratio range of daylight in the ordinary house were calculated at 1/3.4${\sim}$1/6.2, but those of the renovated house were 1/6${\sim}$1/16.2. Therefore. it was found that indoor temperature, globe temperature and uniformity ratio of daylight in the ordinary house maintained more constant than the renovated house by green house effect and earning effect of front balcony.

The increasing population of the elderly is a serious problem in our communities, and a large supply of an apartment house are to accelerate rise of elderly population in apartment house massed areas. The living Pattern of the aged is different from other generations. Accordingly, the living arrangements are induces many problems in the housing life of elderly, sometimes it lower in quality of life. The purpose of this study was to search for the actual family life and needs of the elderly in apartment house. And it was to seize discrepancy between three-generation family and elderly living alone. Also by a user of housing for the elderly, it was to search for an acknowledged and an preference degree about that.

In this study, numerical analysis is performed to investigate the sound radiation characteristics of an apartment house according to the type of the slab system. In order to satisfy the boundary condition of the apartment house, the whole floor is modelled with FEM model for three different structural system: wall, RC, flat slab system. From the analytical results, it Is shown that heavy weight floor impact noise of wail type slab is larger than that of the other slab systems and the noise radiated from the wall have great effect on the sound pressure level. The results also show that the vibration energy of RC or flat slab system is widely distributed over the whole slab, which is main reason that the noise induced by the slab systems is reduced in comparison with wail slab system.

This study is on investigation of sizes, functions and positions of storage space in the house, which is basically necessary for effective using of limit house space. The Storage spaces in Korean vernacular housings are intensively investigated to evaluate their usage and to ex-tend their utility for modern life. Data and materials on the storage spaces in typical houses were taken from the "NamSa Village" and Urban Single-Detached House provided by K.N.H.C. In order to get the fundamental materials, related references are widely investigated and interview and direct visiting have also been made. The results are obtained as follows. 1. There are many kinds of storage space in the rural detached house, however this space could approximately classified as five kinds. 2. The number of "BYUKJANG" and "BANCHIM" are more equipped in apartment houses rader than rural detached houses. 3. There are more kinds of storage space in the public detached houses rather than the public apartment houses. 4. In the apartment houses constructed by private companies, more storage space are generally equipped rather than public apartment houses. than public apartment houses.

The construction cost index and the forecasting model of apartment house can be efficient for evaluating the validness of the fluctuating price, and for making guidelines for construction firms when calculating their profit. In this study the previous construction cost index of apartment house was improved, and the forecasting model based on X-12 ARIMA was developed. According to the result, during the last five years the construction cost, excluding labor expense, has risen approximately to 22.7%. And during next three years, additional 16.8% rise of construction cost is expected. Those quantitative results can be utilized for evaluating the apartment house's selling price in an indirection, and be helpful to understand the variation pattern of the price.

A small apartment housings in Korea, which is built mass-product from 1980s, are dissatisfied, in spite of good condition, due to the growing living areas and changing lifestyle of the residents. Many of them confronted with slum areas and the kinds of housing stock accumulated much more in Korean contexts. For the existing small houses, it could be discuss an adaptation model to the increasing requirement standards of the house residents; wider living area, new facilities and a style of new residence. A social policy for elderly people who are handicap in physical and economical aspects, is home stay system rather than national support. But it is not easy to find the three generation family house in Korea context, specially apartment house. This paper deals with the vertical unification typology of two dwelling units to one, in order to supply three generation houses by remodel existing small apartment houses constructed by Korea National Housing Corporation. The use of convert houses into vertical expansion are expected to be a house of three generation family, it can also enhance privacy against conflictive activities in a house. And also the merging types of two dwelling units into one can be used as a device to get rid of the monotonous characteristics and gain diversity in the declining stock housing.
