The effects of charge system on the removal of water soluble and oily soils from silk fabrics were studied. The charge systems used in this experiments were Light mate DX in petroleum solvent and Light Park MK in perchloroethylene. The detergency was examind with water/detergent ratio and concentration of dry soaps and solvent, respectively. 1. In the case of condition charged with detergents without water, as the concentration of Light Mate DX in petroleum solvent was increased, the detergency of water soluble soils was improved. 2. In the case of condition charged with detergents with water, as water/detergent ratio was increased, the detergency of water soluble soils was improved. Petroleum solvent was superior to perchloroethylene in the detergency as water/detergent ratio was low. 3. In the case of condition charged with detergents without water, the detergency of oily soils of Light Park MK in perchloroethylene was higher than that Light Mate DX in petroleum solvent. The detergency was influenced by characteristics of solvents. The order of the detergency in dry soap concentration was 1.5>1.0>2.0>0.5(%) 4. In the case of condition charged with detergents with water, as water/detergent ratio was increased, the detergency of oily soils in petroleum solvent was decreased. In perchloroethylene, the detergency was not so much affected by water/detergent ratio.

This study was carried out to compare the characteristics of the over weight elementary school students with those of desirable-weight children. Anthropometric parameters such as height, weight, BMI body fat percentile, triceps skin fold thickness were measured. Dietary assessment and blood analysis were performed. The average ages of over weight children and desirable-weight children were 10.9f2.5 and 10.2±2.8 years, respectively. The means body fat percentile of over weight children and desirable-weight children were 27.5±3.7% and 20.2± 3.8%. respectively. Plasma levels of TG. total cholesterol, LDL cholesterol, and HDL cholesterol of over weight children and desirable-weight children were 179.3±30.0. 104.9f26.6, 52.3f6.7 and 178.3±84.l㎎/dl and those of desirable-weight children were 86.1±43.5, 183.7f16.5, 101.0f2.1 and 67.7±20.0㎎/dl respectively. Plasma TG levels of over weight children were significantly higher than those of desirable weight chddren. On the other hand plasma HDL-cholesterol levels of over weight children were significantly lower than those of desirable-weight children Plasma levels of GOT ,and GPT were in normal range in both group. However, GPT level of over weight children was &her than that of desirable weight children. Plasma levels of albumin, globulin and BUN were all in normal range and no differences were found in both groups. Hematologic data did not show any difference between two group except WBC, KBC and Hgb levels which were significantly higher in over weight group than those of desirable-weight children. DAY nutrients intake of over weight children and desirable-weight children were very similar and they were around the Korean KDA levels for each nutrients. However, the intake of calcium of both groups were little over 50% of KDA. The consumption of d e b fiber was very low and the cholesterol intake was very high shorn that the habitual meals of Korean school children were not well balanced.

Purpose: The proportion of centenarians has been increasing in many parts of the world, and the issues of longevity has been the subject of the research concern in recent years. We has conducted the first study with centenarians in Busan, 2006 and this is a follow-up study for prospective research of centenarians in Busan. Methods: The demographic database of Busan Centenarian Study existing in 2006 wasutilized for our studies. Twenty-five centenarians or a proxy were contacted and eight individuals agreed to have a direct interview using a questionnaire. Data were collected from May to June 2007. Results: Of the 2Scentenarians, 2(8%)were men and 23(92 %) were women. The average age was 101.3 years and the highest one was 106 years of age. The majority of the centenarians were living with family, most of those were living with their sons. Among 8 visited centenarians, there were 2 drinkers(2S%) but no one was smoking. Among them, 7 centenarians (87.5%) had regular eating pattern and, 3 centenarians(37.5%) participated social activities. Conclusions: The centenarian in Busan is likely to be healthy and they are living with their family. The centenarians study in Busan has important meaning to understand the health of centenarians.

This study was conducted to evaluate the hospital foodservice management practices in Seoul and to suggest the guideline for the effective foodservice management. Questionnaire survey method were used in this study. Questionnaire were administered to dietitians in twenty hospitals. Data were analyzed for frequency, percentage, χ^(2)-test, and one-way ANOVA using SAS PC Package program. The results were summerized as follows : The number of dietition were less than the required number for efficient foodservice. Centralized foodservice method was adopted in most hospitals and conventional foodservice system was taken in all the hospitals. The space of a kitchen and a dining room were confined and sanitary facilities and working condition revealed problems. Equipped facilities in surveyed foodservice operations were assessed as the insufficient condition, especially, efficient facilities such as a cutting machine were scarecely make up.

This research was carried out to find out the possibility of using Faraday's law in analyzing the electrocoagulation system. Bench-scale reactor equipped with aluminum electrode plates was operated using synthetic wastewater which received sodium chloride for conductivity adjustment. Phosphate was added to the wastewater to induce the precipitation with Al. The amount of aluminum dissolved from the electrodes could be predicted by Faraday's law with a difference less than 5%. This difference was greater at a higher electric current, probably due to the increased solution temperature. However, effect of pH on the dissolution of the aluminum was negligible. The result of this study suggested that the operating condition of electrocoagulation system could be developed using the Faraday's law when the pollutant concentration is given.

This study was to investigate the depression of the aged parents perceived through the conflicts between the aged parents and their adult children. The subjects of the study were 469 old parents, consisted of 234 male and 235 female over 60 years old lives in Kwangju. The datas were analysed by frequency, percentage, mean, standard deviation, oneway ANOVA, t test, Duncan's test and multiple regression using SAS program and the results are as follows. 1) In the conflict between the aged parents and their adult children which the aged parents perceive, the mean values are 32.54 in the case of old father and 34.26 in old mother from the average point. The average values of the depression the aged parents perceive are 26.03 and 28.35 each in old father and old mother and show the level of depression over the middle value. 2) The background variables which show the significant differences of the conflict between the aged parents and their adult children are marital status, age, education, pocket money, health and activity of the aged parents. 3) The background variables which show the significant difference in the depression the aged parents perceive are marital atatus, education, pocket money, health, activity, support type and occupation of the aged parents. 4) The depression and conflict between the aged parents and their adult children show high correlations and the greatest variable as the effect of conflict on the depression is emotional conflict. In addition, significant difference is shown depending on health, value and economic conflict and its explanatory power is 50%.
