The purpose of this study is to investigate the actual usefulness and consciousness of bathrooms and to clarify the preference of bathroom plans by apartments dwellers in Jeonju City. Data was collected through self-administered questionnaires and 343 apartments dwellers were used for this study. The major results are as follows. The bathroom types were mostly unit bathrooms and were not suited with using bathrooms of apartments dwellers. The unit type of bathroom was not comfortable for them and most of them were not satisfied with their bathrooms. They usually used family bathroom instead of private bathroom. They wanted a separate space for different facilities such as a bathtub and toilet, a dressing room, and a fixed clothes chest. Generally apartments dwellers did not prefer unit bathrooms, prefering instead the bathroom plan with separate rooms for the bathroom and toilet, with space for dressing. This study suggests that further studies be conducted on apartments dwellers in other big, small and medium-sized cities. Also, it is necessary to offer bathroom plans which take the size of houses and bathrooms, and the number of bathrooms into account and to survey housing consumers' satisfaction of those bathroom plans.

TProduction's adaptation manufactured construction component is enlarged the result of development in the various construction products and technology. But the pre-fabricated unit bathrooms are not used in spite of many advantages which occupies less than 10% of its market share. This study is for the alternative methods through the on-the-spot experiments to lessen resonance of the wall panel in the Unit bathroom. The results are summarized as follows. Unit bathroom was effective in suitableness part noise control performance when attach sound-absorbing materials. But noises control performance was not better than the general used bathroom. When Urethane (egg container pattern) was applied in the unit bathroom, unit bathroom can be expected for utilization in the construction market field.

This study set out to review the air current fluidity in exhaust common ducts by installing an inlet pipe at a leisure space in the PS(Pipe Shaft)room for the sake of wind power generation with kitchen and bathroom exhaust common ducts of all the equipment and air conditioning shafts in high-rise apartment. The air current functionality of kitchen and bathroom exhaust common ducts was reviewed by analyzing wind velocity changes according to changes to the area of exhaust common ducts through a simulation, changes to the wind velocity of the kitchen hood by applying an external inlet pipe, changes to the usage factor of exhaust common ducts, and changes to wind velocity by altering the form of the ventilator at the bottom of the old exhaust common duct. It was a basic study on the utilization of exhaust wind velocity in exhaust common ducts.

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.

The appeal of sauna is caused by the fact that through that, one can feel Korea's unique temperament and culture; however, because of its being a public facility and flooding of businesses due to excessive supplies of various additional features such as washing, playing, eating, sleeping and health care functions, issues of social resources and environment come to the fore, so it has reached a situation of red ocean that it is difficult to enter the market anymore. Taking these into account, this study focused on developing a thermal technology and design of the housing of an environment-friendly mobile home sauna, making the most use of the sauna's fundamental purpose and settling it as a tourist product, analyzing the marketing research on the existing sauna and considering the recent housing trends and lifestyles for a new concept sauna. Thus, regarding its characteristics and utilization, it was designed smaller than $10m^2$ (3 pyeong) so that it would be easy to install in any space and convenient to move. It can be installed in separate buildings and rest spaces such as country houses, resorts, pensions, camping grounds as well as outdoor houses, custom produced for a measure of pyeong that customers want so as to match up with the Enforcement Ordinance of the Agricultural Land Act in a concept of the farmer's hut and kitchen, bathroom and bathroom can be installed inside according to an option. In addition, regarding its efficacy, in order to give environment-friendly healing effects, materials such as Hinoki Cypress, red clay and hardwood charcoal were used, a fixed indoor temperature of $70{\sim}100^{\circ}C$ was maintained by heating methods such as electromagnetic wave free, energy saving and low-power boiler, and it was made to have excellent effects on fatigue recovery, relieving stress, skin care and diet through far-infrared emission.

In accordance with recent highly advanced economic growth, the demand of leisure life is quite increasing, and also the increase of nature-friendly leisure with health-pursuing concept where human -being enjoys pleasant environment, is to me said as one of recent social traits. Accordingly, it is research the present situation and characteristic of the popularized housing-type accommodating facility, and then this study has discussed on the method how to plan the interior space of such facility to meet with environmental -friendly peculiarity and the object for health enhancement. At first, the program which applied the sustainable design techniques should be preceded, and when planning of interior space, the management method and space planning on the facility and the system should be properly considered in order to enhance the user's health. So to speak, in order to keep and promote the space user's health, those proposing methods such as the followings have been suggested likely as, consideration regarding to air-ventilation and lighting, usage of environmental-friendly material, use of life drainage, custom-typed plane planning, utilization of balcony space, storing furniture and systemization of kitchen space, themed bathroom, inducement of indoor-gardening, and so on. It is expected that this could be applied very usefully to the space plan of the small-scaled housing-type accommodation under planning to develop or renovation.
