This study was conducted with 60 adult males who visited the Atomi Cooperative Clinic(Atomi Dermatology/Pediatrics/Oriental Clinic) in Seoul between May 2003 and December 2004; they were divided into three groups, each of which consisted of 20 persons, according to the level of erythma and then each group was subdivided to consist of ten according to whether they received skin treatment and care. The standard care provided to two groups involved topical steroids and oriental medicines prescribed by a dermatologist and a oriental doctor, respectively. 5th-grade topical steroid ointment was applied to the face and 3rd-grade to the limbs; a oriental medicine was administered in a lukewarm state half an hour after meals three times a day. To determine how special and systematic skin treatment and care was helpful in treating atopy, a skin treatment system was applied to the experimental group while the control group was provided with standard care alone. By using Mexameter(MX18) manufactured by ck-mpa as a measuring tool, the inflammation level was observed at the right antecubital space during each visit to the clinic. In view of the re suits, introduction of the systemic skin care for A. D to legitimate treatment provided by a medical institution is expected to be an appropriate supplementary treatment for adult patients who suffer from frequent recurrence of atopic dermatitis.

The purpose of this study was to analyze the factors influencing life satisfaction in widowhood among older females. Using the sixth Korean Retirement and Income Study (KReIS) supplementary survey data, a total sample of 1,471 women aged 65 or older whose spouse had died were selected, divided into 508 young-old (65-74), 745 middle-old (75-84), and 218 oldest-old (85+). Then, factors influencing the life satisfaction of these three groups were analyzed, based on a combination of perceived health and interpersonal satisfaction levels. It was found that among the young-old group, a higher level of subjective health perception indicated by monthly income and material support and interpersonal satisfaction linked to more frequent participation in community gathering combined for an overall higher level of life satisfaction. For the middle-old group, higher life satisfaction was provided by monthly income, informational support, and material support for subjective health perception and no diseases for interpersonal satisfaction. The oldest-old group with higher life satisfaction referred to monthly income for subjective health perception and no experience in donation activities for interpersonal satisfaction. Based on these findings, this study provides implications for policy and practice to improve the life satisfaction of elderly women who have experienced their spouse's death.

It has been reported that taking a proper amount of calcium and vitamin D helps to increase bone mineral density (BMD) and is effective in decreasing the risk of osteoporosis. This study investigated the supplementary effects of calcium and vitamin D on postmenopausal women who had osteoporosis and used calcium and vitamin D supplements. The study subjects consisted of osteoporotic postmenopausal women who were recruited from the Department of Orthopedics in a university-affiliated hospital. Sixty-seven study subjects were orally administrated 1,000 mg of calcium (calcium carbonate) and 2.5 mg of active vitamin D (1-$\alpha$ hydroxyvitamin D) (cholecalciferol 250 IU) twice a day for a year and a half. BMD and biochemical markers were evaluated and repeated every six months. One year after the intervention test, the bone mineral density of the lumbar spine was significantly increased as compared to the baseline. Six months after supplement administration, the level of serum alkaline phosphatase began to decrease, and afterwards a significant difference was maintained Concentration of 1, 25-dihydroxy-vitamin D at 1.5 years was higher than that of the baseline. In comparison with that of the baseline, the level of urinary hydroxyproline in the study subjects over six months was significantly decreased This study continued that effects such as BMD improvement and changes in biochemical markers appeared at least one year after administration of supplements.

An experiment was conducted to investigate the effects of supplemental copper (Cu) chelates (methionine, chitosan and yeast) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, Cu content in the liver and excreta and the level of total cholesterol in breast muscle and serum of broiler chickens. Two hundred and forty hatched broiler chickens (Ross$^{(R)}$ 208) were assigned to 4 treatments: control, 100 ppm Cu in methionine chelate (Met-Cu), 100 ppm Cu in chitosan chelate (Chitosan-Cu) and 100 ppm Cu in yeast chelate (Yeast-Cu). Each treatment had six replicates of 10 (5 males+5 females) birds each. Weight gain and feed intake tended to be higher in Cu chelate treatments than the control; weight gain was significantly higher in the Met-Cu chelate treatment and feed intake was significantly higher in the Yeast-Cu chelate treatment than the control (p<0.05). Feed/gain was significantly different between treatments in which Met-Cu was lowest followed by the control, Chitosan-Cu and Yeast-Cu. DM availability was increased by Cu chelates among which chitosan-Cu showed the highest DM availability. Cu chelates supplementation tended to increase gizzard erosion index, and Cu content in the liver was highest in the Met-Cu treatment. Supplementation of Cu chelates tended to decrease total cholesterol level in breast muscle and serum but tended to increase the level of HDL in serum. It was concluded that dietary supplementation of 100 ppm Cu in chelates increased weight gain, feed intake and DM availability. Met-Cu was more effective than Chitosan-Cu or Yeast-Cu in improving productivity of broiler chickens.

A feeding trial was conducted to study the replacement value of concentrates with Barhar (Artocarpus lakocha) leaves on growth performance of kids fed a mixed jungle grass-based diet. Fifteen Sikkim local kids, about 4 months of age and body weight ranging from 5.8 to 9.2 kg, were randomly distributed into three groups of five. Kids were stall fed ad lib with mixed jungle grass collected from the nearby forest and native scrubland. The kids in group I received supplementary concentrate (Maize 35%, mustard cake 32%, rice bran 30%, mineral mixture 2% and common salt 1%) at approximately 2% of BW. For groups II and III, 25 and 50% of the concentrate was replaced with Barhar (Artocarpus lakocha) leaves, respectively. Total dry matter intake (DMI) was not significantly different among groups. Digestibility of CP decreased (p<0.05) and that of NDF increased (p<0.01) with increasing level of Barhar leaves in the diet. Digestibility of ADF (p<0.01), hemi cellulose (p<0.05) and cellulose (p<0.01) was higher in groups II and III than in group I. Ruminal pH and TVFA concentration were not significantly different among groups. Rumen ammonia-N concentration decreased (p<0.01) with increased level of Barhar leaves in the diet. Similarly, plasma urea nitrogen and blood glucose levels were reduced (p<0.05) with increasing level of Barhar leaves in the diet. Replacement of concentrate with Barhar resulted in reduced Hb and lower serum iron concentration. Levels of other serum metabolites including minerals were not altered by the replacement. Average daily gain (ADG) was 53.3, 54.4 and 41.8 g/d in groups I, II and III, respectively. ADG was not adversely affected when the level of replacement was restricted to 25%. However, at 50% of replacement ADG was significantly lower than the control (p<0.05). Thus, it was concluded that Barhar leaves might replace 25% of the supplemental concentrate for growing Sikkim local kids fed on a mixed jungle grass-based diet.

Ninety-three weaning children, 8-36 Mo. old wererandomly selected from rural areas of South Korea. Food and nutrient intake level were measured by the weighing-interview method for two consecutive days in December 1976. Their weaning pattern, dietary pattern, food and nutrient intake level were analyzed. A brief summary of 4he finding follows; 1) 80% of the rural children completed the weaning by the age of 24 months. 2) 44% of 8-12 month olds were living only on breast mil while the rest of the age group received regularly a supplementary food. 3) Over half of the 8-36 Mo old children investigated were receiving the same dietary pattern, arbitrarily called 'Diet K'. Diet K consists of rice-Kimchi-seasoning-oil which is the basic components of an average Korean adult diet. This very composition of the diet K and no other variety of food included inevitably result in low intake of vitamin A, iron, calcium and riboflavin for the children. 4) The weaning children were found to be taking all nutrients except niacin in amount far from sufficient to recommended level. Particularly low were the intakes of good quality protein, iron, vitamin A, riboflavin and vitamin C which met only 15%-37% of the recommended level for 12-36 Mo. olds. 5) It was concluded that majority of the rural children of weaning age in Korea are given the simple diet K and feeding the weaning children only with the basic dietary pattern of adults can not meet the nutritional requirements. This is a part of the study supported by the ROKG/USAID Health Planning Project.

This study was conducted to analyze job importance, performance level, and job satisfaction of school and office foodservice dietitians. Self-administered questionnaires were collected from 181 dietitians in the Chungnam area. Statistical data analysis was completed using SPSS v. 14.0. School dietitians were 55% and office dietitians were 45%. Of both, age of 20s and 30s scored 85%; the age of 30s of schools dietians scored 70% while those in office dietians 20s scored 79%. More than 84% of school and office dietitians were university graduates. Total average of job importance of school dietitians was 4.24 and job performance was 3.97 while that of office dietitians was 4.15 and job performances was 3.69. A duty that had a big difference in job importance and performances as a dietitian was 'education of nutrition' (p<.001) and 'self-improvement' (p<.001). According to the meal service except, importance and performances of duties showed a significantly high level (p<.001) for office dietitians, but most measures of job importance and performances showed a high level at school. Therefore, in order to improve job performances and satisfaction for school dietitians, it is necessary to develop systematic and professional education programs for qualification improvement and to grow pride and improve treatment as a nutrition teacher through expansion of appointment. Meanwhile, for office dietitians, it is required to strengthen duty education of 'human resource management' and 'meal service management' through education and supplementary training in companies, on which personal characteristics are reflected.
