  • The objective of this paper is to investigate problems associated with Rural Housing Standard Plans for the Elderly based on the current status of 12 houses belonging to elderly people (60's and over) living in rural areas and engaged in farming activities, and to suggest improvements. The methods employed were a field survey with interviews and literature review. The results are as follows. First, the Plans were deemed inappropriate to prevent the possible accidents in entrance area such as slippiness and falls because the eaves are not long enough. Second, the area of foyer and the volume of foyer storage in the Plans are not enough to accommodate the subject's behaviors and their rural life. Third, rather than using the sink, many subjects preferred to wash simply in the shower while sitting, so the planning of a bathroom can't meet the subject's needs and behaviors. Fourth, the subjects prefer L + DK to LDK but the Plans were designed in the manner of LDK only. Fifth, the subjects have needs for bathrooms belong to the master bedrooms, but only one case of Plans satisfied their needs. Six, bedrooms with the exception of the master bedroom are used as storage in order to make up for a lack of storage space, but many storage space such as dressing rooms and pantries was not taken into consideration in the Plans. Lastly, the planning of storehouses does not meet the subjects' using behaviors for storehouses and the level of desirable capacity of goods.

  • When a human being grew older, followed by visually and perceptually impaired, and dementia, it jeopardizes safety and life unless supportive design is secured for a living environment. This supportive space is based on universal design concept which offers safe-oriented, and simple use by incorporating gender and physical/mental limitation. The study of purppose was to examine the appropriateness of barrier-free standard for seniors' living in apartment through IPA. Chi-square analysis found that satisfaction with BF space is lowered as aging is continued and for female group. Regression analysis indicated that sink was the prime predictor in satisfaction, and stair/elevator was the most important variable. IPA concluded that sink, bath, shower/locker and alert/egress were prime BF indexes to be improved among 14 elements, implying careful design in sanitation area for seniors.

  • The purpose of this study was to promote the utilization of wind velocity of kitchen and bathroom exhaust ducts for wind power generation in high-rise apartments. The research content can be summarized as follows: 1) Nine high-rise apartments were examined for the installation of kitchen and bathroom exhaust ducts located in the pipe shaft (PS) section. After selecting simulation candidates, a simulation was performed with the STAR-CCM+ Ver 5.06 program. 2) Of nine high-rise apartments, seven had kitchen and bathroom exhaust ducts, whose cross section was in the range of $0.16m^2{\sim}0.4m^2$. The area ratio between the exhaust ducts and PS section (cross section of exhaust duct/area of PS section ${\times}$ 100) was on average 3.2%. 3) The simulation results were analyzed. As a result, the smaller cross section kitchen and bathroom exhaust ducts had, the more advantages there were for increasing exhaust wind velocity. If an out air inlet duct is installed to the old kitchen and bathroom exhaust ducts, it will increase exhaust wind velocity by 3.01~3.98m/s and contribute to the proper wind velocity level (3.0m/s). 4) When the simultaneous usage rate between the kitchen and bathroom exhaust fan increased from 20% to 60%, exhaust wind velocity increased. The "entire house holds" condition for exhaust fan operation provided more even exhaust wind velocity than the "some house holds" condition. 5) Exhaust wind velocity increased in the order of amplified (T-3), induced (T-2) and vertical (T-1) top of kitchen and bathroom exhaust ducts. Of them, the amplified type (T-3) was under the least influence of external wind velocity and thus the most proper for kitchen and bathroom exhaust duct tops.

  • Lastly, the problem of filling occurs in the process of concealed joint of adjacent components and was seen in joints between the structure and an electrical or mechanical device. Therefore, the dry processing which replaces wet joint was seen in joints between the structure and a door, ones between the structure and a finishing materials, ones between a gypsum board and electrical device, and ones between a water pipe and a tile finishing. And a process of separating the area of jointed parts in order to eliminate the problem of overlap was seen in joints between a door and a finishing material and ones between a gypsum board on the ceiling and a light. Lastly, an analysis of a process of exposing concealed parts indicated that the problem of filling could be applied to joints between the structure and an electrical or mechanical device and ones between a finishing material and a mechanical device. This study sought out methods to apply Environment Friendly Multi Housing Remodeling that allow easy remodeling as part of environment- preserving policies. It also contains basic data useful to implement long-life houses in the future by presenting a comprehensive design standard for them

  • This study aims to make improvements to the standard estimation process used to estimate reasonable costs for construction work, and to suggest a work crew based estimation using a new cost estimation model. In addition, work crew shift combination and construction process were systematically organized in order to improve the estimation technique and the construction capability of the cement liquid waterproofing work for apartment buildings. In addition, in terms of manpower and productivity, analyses were performed on the cement liquid waterproofing work for apartment buildings with net areas between $84-85m^2$ and $125-184m^2$, and the results were then compared with those calculated using the conventional work-crew based estimation method. Through this study, when the results of this study and those calculated by the conventional method were compared, for apartments with the net area of $84-85m^2$, the differences between specialists were shown to be 1.91 times to 2.13 times on average, while they were 8.82 times to 9.52 times between normal workers on average. For apartments with the net area of $125-184m^2$, the differences betweenspecialists were shownto be 1.89 times to 2.07 times on average, and 8.57 times to 9.38 times on average between normal workers.

  • This study conducted experiments to measure air currents in an experimental building according to external conditions, types of induction ducts, and types of internal sockets by applying an external induction duct comprised of inducing openings and lines and induction units to the kitchen and bathroom vents at the rooftop of a super high-rise apartment building in order to help to improve the venting performance. The study also proposed the optimization of the external induction-style kitchen and bathroom vents capable of wind power generation. (1) As for air current distribution according to vent velocity changes, it increased the venting performance of the kitchen and bathroom by 1.0m/s at vent velocity of 2.0m/s or higher and allowed for wind power generation. (2)As for air current distribution according to external velocity changes, it increased the venting performance of the kitchen and bathroom by 1.2m/s at external velocity of 2.0m/s or higher and allowed for wind power generation. (3)As for air current distribution according to wind direction changes($0{\sim}180^{\circ}$), it was favorable for higher vent velocity when the angle between the external induction duct direction and prevailing wind direction was within ${\pm}30^{\circ}$. (4)As for air current distribution according to induction duct type, the[M1] type combining the inducing openings and lines with the induction units recorded the highest improvement effects in the kitchen and bathroom venting performance by increasing vent velocity by 46%. (5)As for air current distribution according to the changing types of internal sockets where the main ducts of the kitchen and bathroom are connected to the external induction ducts, the venturi tube type[Sv] increased vent velocity by 66% based on the smoothest external inflow.

  • Water supply and drainage noise in the bathroom is recognized as one of the main noises, along with the floor-impact sounds, in apartment housings. Recently, to solve such noise issues, a new construction method of installing the piping on the slab has been adopted. rather than the traditional method of penetrating the piping through the slab between the upper and the lower bathrooms. However, this new method has limitations due to high costs and constructional difficulties. Therefore, this study was conducted to develop noise reducing piping and elbows, where the noise can be reduced simply by replacing the existing pipings. The noise level was measured in a laboratory by installing the horizontal drainage piping (three types) and the elbows (three types) developed in this study. The results showed that the horizontal pipings reduced the noise level in LAmax by 0.3 dB(A)~1.0 dB(A), as compared to the existing pipings (VG2), indicating an insignificant noise reduction effect. The elbow reduced the noise level in LAmax by 5.5 dB(A) ~ 11.5 dB(A), as compared to the existing elbow (DRF elbow), with the result of reducing the noise level at all frequencies evenly. Consequently, it was shown that using the elbows is more effective in reducing the water-drainage noise from the toilet than using the horizontal pipings.
