This study measured radioactive surface contamination in general public restrooms in hospitals and in dedicated toilets for nuclear medicine. The measurement method was measured using Berthold (LB 124, Germany) at the entrance to the restroom, inside the restroom, around the restroom, in the urinal, and around the urinal. As a result of the use of the restroom, there was no dedicated place waiting for patients who received radioisotopes in one of the three hospitals. As a result of measuring the restroom for exclusive use of radioisotopes, all measurement sites in the radioiodine therapy room were the highest, and the results of measuring the public restrooms showed background level contamination at all hospitals except hospital B. However, it was measured as 8.073 Bq/㎠ and 6.426 Bq/㎠ in the urinals in the public restroom on the first floor of the B hospital. Therefore, it is recommended to explain the dangers of radiation exposure to patients and provide a place for patients to wait. In addition, a plan should be sought to prevent patients from receiving radioisotopes from using unnecessary movements and general public restrooms.

This study offers the possibility of a new integrated product of video technology and public culture content. The Development of 'the Urinal of Emotional Type with Screen' will introduce a new sanitary pottery product and it will be a new attempt to combine hygiene pottery product with high-tech electronic product. It is a product development idea that presents the new marketability of the sanitary pottery product with the improvement of awareness of the restroom and the idea of wit through public information notification and advertisement effect. For the commercialization of the product, the prototype will be made through a separate production process with the design of this project, through 3D rendering, 3D mockup and so on. Various product expansions can be consulted with manufacturers after that. It is a new approach of image making with high quality and differentiated pricing strategy, that targeting small-scale business, such as franchise coffee shops and liquor stores with high quality and differentiated pricing strategy, and it will lead the market trend with various marketing availability through differentiated video contents.

In accordance with the growing up to a fine-built national physique on national economic rapid growth, It should be made a partial amendment on the Installation planing of sanitary ware. If users who regard have no problem as using facilities in a unisex toilet, It'll be not only falling down the separation of toilet booth with substantial sanitary problems step by step as follow. 1. The urinal should be pay due regard to such a shape which intercepts stream before the point of dispersion and variations in splash effects according to angles between stream and contact urinal surface with deferent of age and health of users 2. Urinal should be fit for the perineum height of male and so It could be install differently according to the Anatomical Percentile of users.

사람이 가까이 가면 자동으로 문이 열리고 소변기 물이 저절로 쏟아지는 것은 사람에게서 나오는 적외선 때문이라고 한다 .적외선은 가시광선보다 파장이 긴 전자파로 우리가 매일 태양으로부터 받아 따뜻하게 느끼는 에너지 파이다 .가장 재미있는 적외선 응용은 캄캄한 밤에도 사진을 찍을 수 있는 '적외선 사진기술'인데 이는 더운 물체가 열을 발산할떄 일부를 적외선 꼴로 발산하는 현상을 이용한 기술이다.

The most important thing in the restroom is the saving water resource and the removing bad odor. Due to the waste of water and the inefficient operating system, the current urinal receptacles have been gradually replaced by the waterless urinal receptacles in the advanced countries. Therefore, this study investigated the advantages, the characteristics, and the expected problems of the current and the waterless urinal systems. Based on the comparisons between the two urinal systems from this study, the plumbing engineers can positively consider the replacement of the current urinal receptacles with the waterless ones.

The purpose of the study is to identify the degree of relevancy on the facilities for the older persons in the public library buildings. To achieve the purpose, the study has researched and analyzed' the guidelines of the law contributing to the convenience of the handicapped, older persons, pregnant women etc(1999)' for the older persons accessing to the facilities in the public library buildings. And then, the older persons' physical standard sizes in 'Size Korea(1997)' are researched and reconfigured. The study has selected the 10 kinds in such facilities as followed : Door, Accessible Route, Stair, Elevator, Escalator, Ramp, Toilet Stall, Urinal, Table, and Post Box. As the result, the study has identified the relevancies of each facilities based on the older persons's physical standard sizes.

In this study, a method for estimating the amount of urination for men, was suggested and its performance was evaluated. This study is a preliminary one for the development of a health monitoring system that needs un-constraining, non-intrusive and long-term measurements in daily life. To estimate the amount of urination, a wide weighing plate with load cell was built and the difference in a man's weights between before and after urination was measured while he was standing on the plate. The results showed that the amount of urination can be estimated with the measured weight difference under the condition of mild movements. The largest measurement error of the suggested method was 40g, which means that this method can be applied to health monitoring in daily life. It is expected that the results of this study will be the basis for developing practical un-constraining and non-intrusive health monitoring system for daily use at home.

This study aimed to provide the basic data to establish measures for the management of the public toilets and reduction of the offensive odor through the air dilution olfactory method and instrumental analysis about offensive odor dilution rate of public toilets, focusing on the Dong-gu, Daejeon Metropolitan City, Korea. The offensive odor intensities ranged from 10 degree to 669 degrees in the urinal toilets and from 31 to 464 in closet bowl toilets. Meanwhile, toilets that had offensive odor of more than 2.5, of which a civil complaint can be filed, were researched 6 (33%). Offensive odor intensities were different according to the closet bowl toilets of the flush, fermented and conventional methods and the year of their installation, but not according to the area of the toilets. As a result of the instrumental analysis targeting 6 public toilets to identify the offensive odor substance, the maximal concentration of $NH_3$ was 2.04 ppm and the average concentration was 0.67 ppm, but $H_2S$, $CH_3SH$ and $(CH_3)_3N$ were not detected. In the fermented and conventional public toilets were not soaps, air fresheners and wastebaskets. Just 50% of the flush toilets had toilet tissue.
