This study was conducted to evaluate the industry foodservice management practices and to suggest guidelines for the effective foodservice management. The survey for the analysis was conducted through the questionnaires to dietitians. They were divided into two groups: the site color worker and the blue color worker. The questionnaires were received for a response rate of 73.2%. Statistical data analysis was completed using the SAS programs for descriptive analysis, chi-square test, T-test, F-test, and Fisher's LSD. The results of the study can be summarized as follows: 1) The level of education of dietitians and food cost in the employee feeding operations for the blue color worker was lower than the employee feeding operations for the white color worker. 2) The labor productivity indices were not significantly different according to types of workers. But in the employee feeding operations for the blue color worker, full-time foodservice employees worked more than 10.7 hour per week than their counterpart. This indicates the full-time foodservice employees in the employee feeding operations for the blue color worker performed more loaded work compared to the employee feeding operations for the white color worker. 3) Equipped rate of facilities in the employee feeding operations for the blue color worker was low especially in the food preparation and cooking processes.

OBJECTIVES: To elucidate an association of the fragile X syndrome with autism, Southern blot analysis was performed in 66 autistic children aged from 2 years to 11 years. METHODS: Subjects were 66 autistic children with of autistic disorder diagnosed by DSM-IV criteria and Childhood Autism Rating Scale-Korean version. Genomic DNA was extracted from peripheral blood and DNA was used to detect a FMR (Fragile Mental Retardation)-1 gene. Xho/PstI probes and two restriction enzymes (EcoRI, EagI)were used for Southern blot analysis. RESULTS: There were one boy with a methylated mosaic pattern and 3 boys and 2 girls with an unmethylated premutation band. But there was no full mutation pattern. CONCLUSION: Although the possibility of the relationship between autistic disorder and FMR-1 gene has been suggested, the results from this study do not provide any definite association of FMR-1 gene with autism in autistic children.

This study was conducted to examine the differences in perceived body weight and image and various lifestyles based on the self-rated health of university students when gender was adjusted. Five hundred fifty-five participants were asked their perceived health condition, and 58, 289, 160 and 48 students answered themselves as "very healthy", "healthy", "normal", and "unhealthy", respectively. As compared to the other 3 groups, "unhealthy" group showed higher proportions in dissatisfaction of body weight and negative perception of body image (P < 0.01). As health related lifestyles, "very healthy" group reported longer sleeping time than "unhealthy" group (P < 0.05), and had a higher proportion of people with regular exercise. Among the dietary behaviors, the frequencies of followings significantly different among the groups: "Regularity of meal time" (P < 0.01), "Eat protein foods more than twice a day" (P < 0.001), "Eat vegetables" (P < 0.01), "Eat fruit and fruit juice" (P < 0.01), "Eat vegetable oil added foods" (P < 0.01), "Eat seaweed" (P < 0.01), "Eat breakfast" (P < 0.01), "Modulation in animal fat and high in cholesterol intake" (P < 0.01). Particularly, higher proportion of subjects answered "very healthy" had higher frequencies (6-7 times/week) of these dietary behaviors. Overall results suggest that healthy lifestyle including adequate sleeping time, regular exercise, and good dietary behaviors might be potential factors affecting positive perception of health. In addition, positive perception of body weight and image were related with positive perception of health.

BACKGROUND AND OBJECTIVES: It has been reported that various inflammatory and immune reactions are involved in the development and progression of atherosclerosis. We tried to investigate whether the TNF receptor superfamilies are involved in the development and progression of atherosclerosis. MATERIALS AND METHOD: Thirteen carotid atheroma specimens(frozen sections : 10 cases, paraffin section : 5 cases) were obtained from the patients who underwent carotid endarterectomy at Samsung Medical Center and one normal aortic tissue was obtained from a transplantation donor in brain death. In the carotid endarterectomy specimens and a normal aortic tissue , the expressions of R110(TR1), 139(TR2) and DR3(TR3), members of the TNF receptor superfamilies were evaluated by immunohistochemical staining with monoclonal antibodies. Simultaneously, we evaluated the expressions of foam cells, smooth muscle cells, T-lymphocytes and B-lymphocytes. RESULTS: Immunohistochemical analysis identified a strong expressions of foam cells and smooth muscle cells in all atheroma. But, the expression of T-lymphocytes was minimal and that of B-lymphocytes was rare. The expression of DR3(TR3) was seen in all atheroma as strongly positive. The expression of 139(TR2) was observed well in frozen sections, but not in paraffin sections. Whereas, that of R110(TR1) was observed in paraffin sections as weakly positive, but not in frozen section. The areas where the TNF receptor superfamilies were expressed correlated to the area of foam cell presence. The expression of DR3 also correlated with expression of smooth muscle cells. In normal aortic tissue, the expression of inflammatory cells or TNF receptor superfamilies was not observed except smooth muscle cells which were observed in normal artery. CONCLUSION: Foam cells and smooth muscle cells were abundantly present in atheroma. The TNF receptor superfamilies are expressed in the atheroma and the region of expression was coincident with the presence of foam cells.

The principal objective of this study was to assess the nutritional status and dietary quality in low-income elderly individuals residing at home (LH) or in health care facilities (LHCF) with dietitian. This study was conducted via anthropometric measurements, questionnaire interviews, and dietary surveys using a 24 hr recall method with 120 low-income elderly individuals (LHCF=46, LH=74). The average ages of the LH and LHCF group were 76.3 years and 78.6 years, respectively. The LH group evidenced a significantly higher frequency of skipping meals than the LHCF group. The average energy intakes of the LHCF and LH group were 1921.0 kcal and 1443.9 kcal, with a significant difference (p<0.001). Most of the nutrient intake and intake rates for recommended intake were significantly higher among the LHCF group as compared with the LH group. The LHCF group showed significantly higher values for the nutrient adequacy ratio (NAR), the mean adequacy ratio (MAR), nutrient density (ND), and the index of nutritional quality (INQ) by dietary qualitative estimation than in the LH group. The Korean diet diversity scores (KDDS) were 3.66 for LH group and 4.93 for the LHCF group, thus were significantly higher in the LHCF group than in the LH group. The results of the present study demonstrate that the LH group appeared to experience more dietary problems than the LHCF group. It was suggested that nutritional education is needed for low-income elderly individuals living at home, in order for them to learn proper dietary management. This can be achieved via educational programs in social welfare institutions, incentives toward employment as a dietitian, and implementation of community-based support.

Bacterial endophthalmitis is an ocular emergency that requires rapid diagnosis and therapeutic decision making. The introdection of intravitreal injection of antibiotics has been a major advancement because it has resulted in a marked improvement in visual outcome. The intravitreal injection of steroids may be potentially useful in the treatment of endophthalmitis and other ocular inflammatory diseases. Forty eyes of pigmented rabbits were used, and divided into two groups. Group I was eyes without vitrectomy. In the right eye, 100 microliter of 1mgvancomycin, 400 microliter amikacin and 400 microliter dexamethasone injected was done. Group II was eyes with vitrectomy and lensectomy. At 2 weeks after lens and vitreous removal, rabbit eyes received an injection of a combination of 1mg vancomycin, 400 microliter amikacin and 400 microliter dexamethasone in right eye and BSS in left eye. The effect of combination injection was examined by light and transmission, scanning electron microscope at 3 days, 1 week, 2 weeks and 6 weeks following injection. The injection of combination without vitrectomy produced no toxicity. After injections of either combination or BSS after vitrectomy, macrophages were observed on the surface of retinal pigment epithelium and disorganized outer segments. This finding seems to be produced by vitrectomy procedure rather than drug toxicity. These results supports the hypothesis that the injection of these combinations is not toxic to aphakic/vitrectomized eyes.

OBJECTIVES: Midlife women's knowledge, positive attitudes and management toward menopause may improve the quality of peri and post-menopause life. This study was to identify correlations of the knowledge, attitude, symptoms and management toward menopause in middle-aged women. METHODS: We used a cross-sectional questionnaire study applying to 231 perimenopausal and menopausal women aged from 40 to 59 years old. The completed data of 189 perimenopausal and menopausal women were analyzed through t-test, ANOVA and pearson's correlation coefficient using the SPSS statistical programme. RESULTS: The menopausal women showed significantly higher physical symptoms than perimenopausal women. The menopausal women showed significantly higher psychosomatic symptom than perimenopausal women. There was a significant correlation between the menopausal attitude and management. CONCLUSION: This study suggests that the fundamental data of developing midlife women's symptom index (MSI) and providing menopause management could be a strategy to encourage successful menopausal transition in middle-aged women.

Perfluorocarbon liquids(PFCL) have been used as an intraoperative tool for repair of complicated retinal detachment with improving surgical results. However, little is known about the potential toxic effect of PFCL that remain in the eye after surgery to anterior segment tissue. In this study we evaluated the effect of this substance on the corneal tissue. Eight rabbits underwent injection of 50 micro l of perfluorodecalin in the anterior chamber of the right eyes. The left eyes were injected with the same amount of balanced salt solution(BSS) as a control. The clinical appearance of the eyes were recorded at three days, one week and two weeks after injection, and histological examination was done two weeks after injection. The differences of intraocular pressure(IOP) between the right and left eyes were not statistically significant at three days, one week and two weeks after injection, and all of right eyes showed inferior bulbar counctival injection for same periods. In the histological examination of cornea exposed to PFCL, the number and the height of endothelial cells were reduced and decreased, respectively. These findings suggested that PFCL may have a toxic effect on the corneal endothelial cells.

The purpose of this study was to investigate the age-related changes of cardiovascular disease risk factors and inflammatory markers in non-obese Korean women. Subjects were 112 women over 20 years old with body mass index (BMI) less than 30 kg/m2 and were divided into 3 groups (< 40 years, 40~59 years, > or = 60 years). Mean weight and BMI in the oldest group were significantly higher than those in the other 2 younger groups (P <0.05). Mean total cholesterol, triglyceride, LDL-cholesterol and apolipoprotein B/apolipoprotein A1 ratio (BAR) in the oldest group were significantly higher than those in the youngest group (P <0.05), and mean HDL-cholesterol of the oldest group was significantly lower than that of the youngest group (P <0.05). The older-aged group showed significantly higher mean values of atherogenic index (AI) and LDL/HDL ratio (P <0.05) than the respective younger-aged group, and AI was significantly correlated with age, nitric oxide and thiobarbituric acid reactive substances (P <0.01). In addition, mean vascular cell adhesion molecule-l (VCAM-1) tended to be higher in the older-aged group than the younger group. Tumor necrosis factor-alpha, a proinflammatory maker, was significantly positively correlated with serum homocysteine, a cardiovascular disease risk factor (P <0.01). In addition, a significantly positive correlation was observed between C-reactive protein and BAR (P <0.01). Overall results suggested that the aging might affect the increase of cardiovascular disease risk factors including the serum lipid profiles, weight and BMI, and age-related increases of weight and BMI might play a role in changes in certain biomarkers of inflammation.
