This study investigated the water saving technology for the toilet stool system in a water closet. Since in 21st century water would be the prospected factor to measure the wealth of a country instead of the oil, water saving technologies in the toilet stool in a closet system is getting more important than the cleaning stool and the reducing noise performances. According to the statistics in Korea the percentage of using water in toilet is about 27% to the total amount of water used. Therefore, this study theoretically approached the possible amount of water saving and suggested the new variable position straight trap device in the toilet stool system.

현대인들은 개인별로 많은 종류의 옷을 가지고 있고 옷장은 단순히 옷을 보관하는 용도뿐만 아니라 옷장의 상태에 대한 관리가 중요해졌다. 본 논문에서는 스마트 옷장의 사용자는 일상생활의 편리함 및 최적의 옷장 상태를 제공하는 스마트 옷장을 제작하여 다양한 환경에서 사용 가능한 스마트 가구개발의 가능성을 제시하였다. 개발된 시스템에서 Arduino MEGA를 기반으로 블루투스 연결을 통한 앱 인벤터와 터치식 LCD를 사용해 옷장을 제어되며, 날씨에 따라 사용자에 어울리는 옷을 추천해준다. 또한 LCD 스크린을 통한 실시간 날씨 상태 확인, 필요에 따라 손쉽게 환기가 가능하도록 하여 시간 절약과 편리성에 의미를 둔 스마트 옷장을 설계하였다. 사용자의 적합한 옷을 어플리케이션으로 추천할 수 있도록 Arduino와 app inventor 프로그램을 통해 구현하였다.

The study about a drainpipe of water closet was performed as reduction of drainage noise for water closet. The Drainage noise is composed two characteristics. One is Low frequency noise and the other is high frequency noise. Low frequency noise is dominant in the first stage and high frequency noise is dominant in the last stage. This is due to water splashing and that is caused by formation of chamber pot. In this experiment, for the purpose for reducing the noise, we choose the hollow rubber pipe element. As a result, we reduced drainage noise about 11㏈A.

This study investigated automatic malodor exhaust ventilating methods in a water closet system. Even though these days advanced equipment has been applied into the toilet in a building or house, the odor due to the evacuating the bowels should be carefully removed to maintain clean and pleasant toilet. Therefore, this study thoroughly considered the main causes of the malodor problems and suggested the best applicable methods to the closet system.

The study was performed as reduction plan on drainage noise in a toilet, which of noise in plumbing systems was being indicated the major point at issue in apartment houses. The reduction plan is four items, which are water closet, isolating system for the base of water closet, low noise drainpipe, and a ceiling tex. Through the result of experiment, it was showed that noise reduction is about 9dB(A) within a toilet and above 5dB(A) in a bedroom.

While cognition about an environment pollution becomes important recently, the intense pollution measures about an indoor air environment is required. In the case of building indoor environment, over 80% of modem people is living in building and these days an interest of building interior materials which becomes a reason for indoor environmental pollution in public house, office, is increasing. An experimental measurement method of this study is as follows. (1) American EPA TO-17, ASTMD5116-97, measurement method in VOCs experiment of Japanese closet industrial association (2) 2.4-DNPH cartridge method in HCHO experiment, based on American EPA TO-11 and measurement method of Japanese closet industrial association (3) standard compound is analyzed by using HPLC after solvent extraction process (4) paint and furniture are selected as measurement objects (5) we also made small chamber to grasp an emission characteristic of HCHO and VOCs and to get an environment-amicable forecast model through it, then we developed the model which can forecast emission rate by chamber experiment.

This study aims to evaluate noise emission from water supply and drain installations in apartment bathroom. These noise were one of the most annoying noise sources in apartment houses. Especially, drain plumbing system have used bellow bathroom ceiling, it was very discomfort to hear the noise in bellow apartment. Noise of closets and faucets were measured which were main noise source, then these noise were evaluate and analyzed the emitting characteristics varying the supplying water pressure. As increasing the water pressure, also total noise level of the water supplying stool noise and faucet noise were increased. Especially the water closet showed remarkably the increasing noise level in middle and high frequency bandwidth, while the noise level of faucets increased in $50\;Hz{\sim}250\;Hz$ of low frequency bandwidth. Vortex closet were favorable to syphon closet, and lever faucet were favorable to conventional lavatory faucet on reducing the noise. Above these results could be used in basic data establishing KS (Korean Standard) for evaluation and rating procedure and measures reducing these noise.

The purpose of this study is to identify more types of residents in medium-sized apartments in Seoul by lifestyle that has been used as a variable of space planning and to investigate and present bathroom design appropriate for characteristics of each resident type. The article examines the general characteristics, lifestyle types, and preference for the bathroom design. A total of 642 samples, acquired via internet survey, were analyzed with the statistical computer program SPSS PC+ window version 16.0. The conclusion of the article are as follows: 1) The lifestyle of users living in medium-sized apartments are categorized into 4 types: trend seeking, aesthetic seeking, family seeking, information seeking types. 2) The preference for the bathroom design of trend seeking type, the toilet is a bidet-builtin type and the washstand is a semi-counter type and the bathtub is a spa type and the shower booth is a bathtub-extending type. The storage closet is a upper-fixed type with two sides, the finishing materials are tiles and PVC monorium, and light built in a wall. 3) The preference for the bathroom design of aesthetic seeking type, the toilet is a bidet-builtin type and the washstand is a semi-counter type and the bathtub is a whirlpool type and the shower booth is a steam-sauna type. The storage closet is a upper-fixed with one side and opened closet, the finishing materials are tiles. 4) The preference for the bathroom design of family seeking type, the toilet is a bidet-builtin type and the washstand is a stand type and the bathtub is a reclamation type and the shower booth is a partition type. The storage closet is a upper-fixed with three sides. 5) The preference for the bathroom design of information seeking type, the toilet is a bidet-builtin type and the washstand is a semi-counter and the bathtub is a spa type and the shower booth is a partition type. The storage closet is a upper-fixed type with two sides. The results of this study may be used as basic data in planning bathroom design for housing supply for housing suppliers, and used as significant information for residents to identify their own types that can be referred when they select apartments to live in.
