Recently, the long-term care insurance for the elderly was carried out according to the elderly is increased rapidly and the formation of sympathy that a nation and society try commonly to share health and welfare promotion of the elderly. The purpose of this study is to analyze the present status of nursing home after that the long-term care insurance is enforced in chungcheongbuk-do and to utilize as basic data. The study limited its survey to those facilities that refer to the Ministry of Health and Welfare data, that had the capacity of more than 50 people. The result are as followings. Firstly, most of the nursing home were located on the outskirts of the city. But it must be constructed in the city center if the recent deinstitutionalization trend is reflected. Secondly, notwithstanding the provisions of the Elderly Welfare Law, if the Livability and amenity are considered, the plan of a single or a twin room is needed. The ondol(溫突) system bedroom for the safety of the elderly had to be planned and for the color planning of a bedroom, a heating, the furniture, the form of a door, corridors, etc. should be partly improved. The fastener in which it is appropriate for the main exit, a stair, an elevator, the lighting device, and etc. is needed and the installation of a wandering path for the dementia patient and etc. is required. Thirdly, most of the dining room arranged on the first floor but it is not nearly used and it used for employee or the other use. Therefore, we have to consider the system in which it can deliver the meal to a bedroom. If the smell of the elderly and etc. is considered, the sufficient height of the floor should be reflected for the ventilation equipment. Lastly, The improvement of the existing law are required.

This study was performed to estimate total dust concentrations and particle size distribution of wood dust in the furniture and sawmill industries. To compare total wood dust concentrations, two samplers recommended by the American Conference of Governmental Industrial Hygienists and by the National Institute for Occupational Safety and Health were used. Concentration data were analyzed by paired-t tests using the SAS program and two parameters of the particle size distributions were determined by histogram. The results were as follows: 1. Particle size distributions showed a unimodal pattern in cutting and a bimodal in sanding operations. Mass median aerodynamic diameters(MMAD) were $17.35{\mu}m$ in cutting, and $1.39{\mu}m$ for small mode and $18.89{\mu}m$ for large mode in sanding operations. The proportions of particle size larger than $9.8{\mu}m$ estimated by the impactor were 61.16 % in cutting and 62.33 % in sanding operations, respectively. 2. The average personal total dust concentrations measured by IPM sampler were $17.12mg/m^3$ (GSD=1.45) from indoor samples, $2.97mg/m^3$(GSD=1.90) from outdoor samples in cutting, and $8.01mg/m^3$(GSD=1.58) from sanding operation. And those of by 37 mm closed-face cassette were $9.12mg/m^3$(GSD=1.46), $1.06mg/m^3$(GSD=1.99) from cutting, and $3.32mg/m^3$(GSD=2.16) from sanding operations. 3. The average area total dust concentrations measured by IPM sampler were $1.88mg/m^3$(GSD=2.04) from indoor cutting, $4.76mg/m^3$(GSD=2.83) from indoor sanding operations. And those of by 37mm closed-face cassette were $0.49mg/m^3$(GSD=2.34) from cutting, and $1.32mg/m^3$(GSD=3.03) from sanding operations. 4. The ratio of personal total dust concentrations measured by 37 mm closed-face cassette to those by IPM sampler were 35.7 %, 53.3 % from cutting, and 41.4 % from sanding operations. 5. The ratio of area total dust concentrations measured by 37 mm closed-face cassette to those by IPM sampler were 26.1 % from cutting, and 27.7 % from sanding operations. 6. A statistically significant difference of total dust concentrations between the 37 mm closed-face cassette and the IPM sampler was found.

The main purpose of this study was to treat pica in a 2.8 year old child with severe mental retardation along with autistic tendencies. His developmental age ranged from 12 to 15 month on the DDST and he had no means of communication. He was on Tegretol 200mg for seizure control. His pica involved thumb sucking, putting toys into his mouth, and licking furniture wherever he went Besides pica, he had a rumination problem. The treatment strategies for his pica consisted of two phases : In phase 1, The child was taught toy play through a 3-step guided compliance training, while his pica and rumination behaviors were recorded to investigate whether active toy play could effect any change in the untreated pica and rumination behaviors of this child. In phase 2, a facial screening was used as a means to control his pica, while his rumination was recorded to see whether controlling his pica could bring any change in the untreated ruminating behavior. The results showed that the facial screening was very effective in decreasing his pica from an average of 18.6 times per 15 minute in the baseline to 2.3 times post-treatment. Response covariation was observed across pica and rumination while toy play compliance training alone was being conducted, and covariation across rumination was observed while pica alone was being treated with facial screening.

When you move to a new home, or when you change the wallpaper or flooring of your home, office, etc., you can enjoy the joy of opening your new home with the sick house syndrome, such as the stinging smell and stinging eyes that may appear after the interior work. It is only a moment. Volatile organic compounds from building materials, adhesives, wallpaper, and paints used in new buildings or new furniture cause residents' health and discomfort in indoor life. These volatile organic compounds include benzene, toluene, acetone, and styrene, as well as the representative formaldehyde, and these substances are slowly released over a long period of time, causing acute or chronic diseases to residents. As a method for removing organic volatile substances, physical methods using adsorption, chemical methods for converting volatile substances to other substances, or a mixture of the two are mainly used. In this paper, a sustained release chlorine dioxide gel pack obtained by a method for controlling the reaction rate of a reactant and the release of a product is mixed with a zeolite adsorbent having an optimized hole diameter to adsorb and decompose and remove formaldehyde suspended in the air. I would suggest an effective method.
The purpose of this study was to investigate the eating behavior and life habits of kindergarten children 5 to 7 years old in Chuncheon area. This study was conducted in December, 1996. Anthropometric indices(height, weight, skinfold thickness, mid-arm circumference) were measured and body mass index(BMI), Rohrer index, arm fat area were calculated to estimate children’s body fatness. Also the eating behavior and life habits were determined tv using questionnaire method. The results were as follows: Body fat rate of the children was almost normal according to Rohrer index and BMI. There was significant difference in birth weight between male and female. The problems of the eating behavior were frequent skipping breakfast and eating-out. The rate of the children who took snacks 2 times a day was 46.9%. Most children tended to take sweet snacks such as ice-cream, chocolates, cookies, and they tended to prefer meats and fishes to vegetables. The rate of breast feeding was 28.3% and the rate of weaning foods prepared at home was 61.1%. Many children preferred indoor activities such as watching TV, toy furniture play, building block to outdoor activities such as roller-skating, cycling, jogging in their spare time. The rate of the children who took exercise regularly was 15%. Children tended to eat kimbap, fried chicken, ramyeon more frequently in various instant foods. The intake rates of fruit juice and barly tea were relatively high and children's favorite fruits were watermelon and mandarin orange. From this results, skipping breakfast, frequent eating-out and the monotony of food preference appears to cause imbalance in nutrient intakes of the children and to have bad influence on children’s health. Accodgingiy, the comprehensive nutrition education and proper modification program should be needed for the children and their parents to correct the eating behavior and life habits. The reasonable exercise programs are needed to motivate outdoor activities of the children, and the importance of breast feeding and weaning foods should be emphasized to lactating women and pregnant women.
Formaldehyde(HCHO) and total volatile organic compounds(VOCs) can cause adverse health effects to the building occupants and may contribute to symptoms of 'Sick Building Syndrome'. These chemical contaminants are emitted from furnishings and electronic equipments as well as building materials. The purpose of this study is to measure and analyze VOCs and HCHO emission concentration from furnitures composed of wood materials including various chemicals by the large chamber method. This paper presents experiment results on the emission concentration of TVOCs and HCHO released from furnitures, such as bed, kitchen, sofa and table by a large chamber($24m^3$). The temperature and air humidity in the chamber are controlled to $25{\pm}1{\circ}C$ and $50{\pm}5%$ for this experiment. When the air change rate is $0.5hr^{-1}$, the background concentrations within the large chamber are below $50{\mu}g/m^3$ for TVOC, $5{\mu}g/m^3$ for HCHO and individual VOCs. The study is investigated the characterization of the chemical emission TVOC and HCHO concentrations and unknown VOCs from 6 furnitures.
As Korea has undergone rapid modernization, urbanization and industrialization, women's social participation has increased. Accordingly, child care facilities have shown continuous growth in numbers. However, according to research, child care facilities in Korea lag behind those in other nations in terms of quality. Given that, it seem urgent to enhance the quality of child care facilities and improve their indoor environment. Above all, overall atmosphere, colors and finishing materials are connected directly with educational effects as well as feelings and health of facility users. This study assesses the current state of child care facilities and preferences by focusing primarily on interior atmosphere, materials and colors. For This Study, 7 facilities were surveyed, and 46 subjects were participated for this study. The findings suggest that "pretty" style is preferred to "natural" style. As regards flooring material, wood floor is preferred. It is recommended to lay pastel colored carpet or PVC flooring material to the wood floor. As for wall, it is desirable to divide the wall spaces by adding wood and painting to simple wallpapers. In case of the ceiling noise absorptive material is recommended to use instead of wallpapers. For the doors, it is desirable to use contrasting materials and colors given accessibility for children. In the meantime, rather than strong primary colors, soft color or pastel colors are desirable for furniture. This study has limitations because of insufficiency of case study samples. However, it is significant in that the study results may be used as primary source of information to improve the environment of child care facilities.
The purpose of this study is to identify the characteristics of aging-friendly technology that can be integrated into future smart homes in an aging society.

Through those results, the aging-friendly technology is expected to alleviate a wide range of issues in aging society.
There are physical and chemical method for removement of a lacquered layer existing on the surface when gilding an iron Buddha, these caused environmental pollution by surface degradation and is very noxious for conservation scientist's health. Thus, on this study, we conducted a lacquered layer removement experiments using Nd:YAG Laser which is contactless and eco-friendly. Specimens were made by polishing $5{\times}5$ size of iron(99.9%) specimens surfaces evenly and by differing of number of coating of unrefined lacquer, so there were thickness differences of $10{\mu}m$, $20{\mu}m$, and $30{\mu}m$. The laser machine used in this study was Nd:YAG Laser, and we used two wavelength modes; 1064 nm(160~180 mJ) for infrared light region and 532 nm(50~350 mJ) for ultraviolet light region. The experiment done by investigating the transition of specimens' surfaces with laser wavelength, energy, and numbers of investigation. The remain amount of lacquered layer surfaces before/after laser irradiation was investigated by stereoscopic microscope, observation by SEM, Non-contact Surface Roughness Measurement Device, and FT-IR etc. As a result of each analysis, we could verify the thickness of $10{\mu}m$, $20{\mu}m$ of lacquered layer removed without surface degradation when using 1064 nm wavelength with $1.0J/cm^2$ density. We could find out that Nd:YAG Laser is effective for removing remained lacquered layers when gilding an iron Buddha. In the future, when not only the metal has made various studies also wood lacquered furniture or the like, it seems to be utilized to remove the lacquer without surface damage.
