1904년 대한제국 정부에서 간행한 $\boxDr$경상남도가호안$\boxUl$은 총 31개군 가운데 11개군의 자료가 현전하는데, 이 자료는 당시 이 지방의 민가에 대한 상세한 정보를 담고 있다. 이 논문은 제1차자료인 가호안의 분석을 통하여 동ㆍ면ㆍ군별 가좌의 토지등급ㆍ가옥의 규모, 가좌와 가옥의 소유관계, 초ㆍ와가의 분포 등을 파악한 연구이다. 가호안의 분석결과 전체 가호의 약 20%는 사유지 또는 국공유지를 임대한 가좌에 지어졌다. 또한 가옥의 90%는 방 한칸 또는 두칸에 부엌이 딸린 집이었으므로 지역의 가옥규모는 2.75칸에 불과하였다. 다시 말하면 100년전 경상남도의 가옥규모는 조선시대의 이상 가옥형인 삼간초옥에도 못미쳤던 것이다. 이러한 열악한 주거조건 때문에 1인당 점유공간이 2-4평방미터에 불과하며 결과적으로 수용가능한 가족의 수도 4인 내외로 한정되었다.

The wind pressure distributions were analyzed to provide fundamental criteria for the structural design on e single-span arched house according to the wind directions through the wind tunnel experiment. In order to investigate the wind force distributions, the variation of the wind force coefficients, the mean wind force coefficients, the drag force coefficients and the lift force coefficients were estimated by using the experimental data. The results obtained are as follows: 1. When the wind direction was normal to the wall, the maximum positive wind pressure along the height of the wall occurred approximately at two-thirds of the wall height because of the effects of boundary layer flow. 2. When the wind direction was 30$^{\circ}$ to the wall, the maximum positive wind force occurred at the windward edge of the wall. When the wind direction was parallel to the wall, the maximum negative wind force occurred at the windward edge of the wall. 3. The maximum negative wind force along the width of the roof appeared around the width ratio, 0.4, and that along the length of the roof appeared around the length ratio, 0.5. 4. According to the results of the mean wind force coefficients analysis, the maximum negative wind force occurred on the roof at the wind direction of 30$^{\circ}$. 5. The wind forces at the wind direction of 30$^{\circ}$ instead of 0$^{\circ}$ are recommended in the structural design of supports for a house. 6. To prevent partial damage of a house structure by wind forces, the local wind forces should be considered to the structural design of a house.

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.
