We implemented an execution health officer system in this research. This system is the execution and can manage the health of the user systematically. A home network standard was not set up yet. The comparison observed geungedda suitable in a health officer system standard. We made efforts to realize the medical treatment network not to be activated yet. We implemented also a remote medical examination and treatment service a former chateu service alimentotherapy service. We will offer different service field and many the gear potent service.

The goal of this study is to develop treatment methods for improving the noise quality of Home Appliance Drain Pumps. Developed treatment methods covers the various methods including the control of the water level through the developed electronic circuity and the various modifications over the design of impeller and fan units. In the first part of the studies Dominant noise sources of the pumps are analyzed. Specific noise problems of the pumps are classified on the basis of mechanic and magnetic origins. Factors including the pressure variations at suction head, magnetic interactions with structure, specific fan noises are studied sequentially. The second part of the studies are considered for development and application of treatment methods. Results denoted the basic problems and ways to improve the noise quality by treating the dominant soureces of drain pumps.

The most demanded bimetals in home appliances are manufactured by mainly cladding process and these are mainly consist of Cu alloy and Ni alloy. But it is very difficult to clad these alloys, because the brittle ${Cu_3}{O_4}$ oxide film formed easily on Cu alloy surface during cladding process. Clad rolling and heat treatment processes were applied for the development of bimetals by using the Ni alloy and the 3 types of Cu alloys. Optical microstructure was observed and micro-hardness, specific resistance, deflection were measured from the manufactured new bimetals specimens.

This study takes an effort to suggest solutions for medical service consumers' sovereignty. Specifically, consumer evaluation, information seeking level, and affecting factors on information seeking level were explored in terms of medical service. In present study, medical information included medical institution and doctors, prescription, diseases, medical treatment and medical expense. Medical service consumers' information seeking is identified as consumers' own efforts to acquire medical information through various sources. The analysis results suggested that consumers' information seeking level is even lower, while their evaluation level is somewhat low. Moreover, the result for information seeking level by consumer characteristics implied that people who have high education, high economic status, medical knowledge, and high attitudes for consumer right are active information seekers. Finally, consumer attitudes for right appeared most influential factor on information seeking level, implying direction for medical service consumer education.

Nylon fabrics and stocking were dyed with artemisia dyeing solution, dyed with the natural dyestuffs that were manufactured from chestnut hulls by boiling in 0.5% NaOH solution and powdering in freeze dryer, and dyed with gromwell dyeing solution. Dyeabilities on nylon fabrics and stocking were good because of being amine group. All the dyed fabrics & stocking showed excellent in color fastness to laundering, and as poor as grade 1 to light fastness. But Light fastness of them could be improved to grade 3 or 4-5 by treatment with gallic acid and by repeated dyeing. Antimicrobial activities of the fabrics dyed with artemisia and gromwell against Staphylococcus aureus and Candida albicans were excellent in the aspect of bacteriostatic and fungistatic. There were not any distinct differences between mordant and non-mordant fabrics.

This study was to examine the dry cleaning resistance of chrome bonding in the chrome-tanned garment leathers, and to analyze their chrome content. The results are as follows: 1. The average percentage of the chrome content (as $Cr_2O_3$) in the chrome-tanned garment leathers was 2.7%. 2. By the dry cleaning treatment and its numbers, the values of chrome content were little affected. 3. The resistance against dry cleaning with perchloroethylene $(Cl_2C = CCl_2)$ of samples was confirmed.

PET FDY was heat set at various temperatures and times and the microstructural changes was investigated through crystallinity, birefringence and melting behavior analyses. Crystallinity of heat set PET increased as the treatment temperature and time increased. Birefringence also increased as temperature and time increased. The melting behavior of heat set PET was as follows: In most cases, PET showed double melting peaks. As temperature and time increased, form II crystal became sharp and increased in size, and form I crystal decreased in size. The slower the heating rate, the higher the programmed heating effect during DSC analysis.

During a period from October 1st to November 15th in 1971, We made a survey on hygienic status of kitchen utensils used at 270 college student's home in 9 districts of Seoul city. The results obtained could be summarized as follows. In bacteriological study on the kitchen utensils 20.7% of them revealed contaminations with general bacterial counts of over 100/m1 and 20.0% of them with coliform bacteria. It was probable that degrees of bacterial contamination of the kitchen utensils were chiefly attributable to levels of education of housewives and living standard of individual household. Factors that were presumed to be directly responsible for the contamination were sources and storage of water and methods of washing the utensils. One of the major sources of contamination was derived from the use of a piece of cloth (Hangjoo) to wipe up the utensils after soashing. Hygienic treatment of Hangjoo in urgently needed. Otherwise, it is desirable not to used the Hangjoo and leave the utensils dry after washing them with boiling water.

Due to the recent rapid industrialization worldwide, the number of pediatric asthma patients is increasing. And the fine dust containing heavy metals is linked to the characteristics of high toxic lead due to the increase heating in factory operation and automobile driving. It is the reason of arsenic increasing. In the treatment of pediatric asthma patients, drug administration, oral drug entry, and HMPC (Home Management Plan of Care) are used. In this paper, we analyze the relationship between the onset of asthma and the method of prescription for specific childhood asthma in the United States using EM (Expectation Maximization) and MDL (Minimum Description Length) algorithms. And the association is also analyzed by comparing the nature of specific congestion between the past prevalence of digestive asthma and the recent prevalence of environmental pollution.

Clad rolling and heat treatment processes were applied for the development of bimetals by using the Ni alloy and the 3 types of Cu alloys. Optical microstructure, micro-hardness, specific resistance, and deflection and line profile of newly processed bimetals specimens were observed and measured in this paper. Inter-diffusion was observed between Cu and Ni element in the interface of heat treated Cu alloy and Ni alloy clad material. The C1220 and Invar36 clad material showed the best property of deflection among the 3 kind of clad materials.
