This study evaluated the effectiveness of a visiting inspection and knowledge-based food safety education program for cooks in child care facilities provided by the Center for Children's Foodservice Management (CCFSM). The research was conducted among cooks at 91 child care facilities; 56 existing facilities had been enrolled since 2011 and provided with the inspection and education program for 2 years and 35 new facilities were enrolled in 2012 and provided with the program for 1 year. The food safety knowledge of the cooks of the two groups were compared by the presence and duration of inspection and education programs provided by the CCFSM. The total mean score for food safety knowledge was 18.48+/-3.09, with a group score of 19.34+/-2.68 for the existing facilities and 17.11+/-3.25 for the new facilities (P<0.001). There was no significant difference between groups in the knowledge of the personal sanitation. According to a post-test for food safety knowledge in the two groups after the completion of a one-year program on food safety by CCFSM, the mean score of food safety knowledge increased by 2.92 to 20.03 for cooks of the new facilities and both groups had significantly higher mean scores than pre-test (P<0.001). There was no significant difference in the mean score of each group by post-test. Thus, the one-year continuous program by CCFSM was effective in improving food safety knowledge of the cooks of the child care facilities.

OBJECTIVES: The purpose of this study was to investigate how to manage food allergy of pre-school children, focusing on the current status of the food allergy in childcare facilities in Hanam which have less than 100 children. METHODS: Targeting 159 preschool childcare facilities, survey was carried out for a month in March, 2015. Recovery rate was 66.7%. 106 surveys out of 159 were available for analysis using SPSS statistical program version 19.0. RESULTS: Among 106 facilities, 58 (54.7%) reported that none of their children had a food allergy and 48 (45.3%) reported one more children had a food allergy. Total number of children having a food allergy was 71. Among them, the occurrences of food allergy in males were significantly more than that of the females (p < 0.001). Further, children under 2 years of age had significantly more food allergy than the other ages (p < 0.001). The allergic inducing foods were nuts (23.3%), egg (17.8%), milk and dairy products (16.4%), fish and shellfish (13.7%), instant foods (12.3%), fruits (8.2%), soybean (4.1%), meat (2.7%), and cereals (1.4%) in order, and 6 children out of 71 were allergic to more than 2 food items. The clinical symptoms of the food allergy were a skin reaction (87.9%) and an oropharyngeal & respiratory reaction (12.1%). Majority of childcare facilities (80.3%) didn't serve alternative foods for children with food allergy. Necessity for food allergy education was significantly higher in facilities with food allergy issues than without such issues. CONCLUSIONS: The Center for Children's Foodservice Management need to educate workers of childcare facilities and parents about managing food allergy and enforce a plan to provide alternative menu to children with food allergies.

OBJECTIVES: This paper proposes a measurement method to quantify the abnormal characteristics of the broken parts of ribs using local texture and shape features in chest radiographs. METHODS: Our measurement method comprises two steps: a measurement area assignment and sampling step using a spline curve and sampling lines orthogonal to the spline curve, and a fracture-ness measurement step with three measures, asymmetry and gray-level co-occurrence matrix based measures (contrast and homogeneity). They were designed to quantify the regional shape and texture features of ribs along the centerline. The discriminating ability of our method was evaluated through region of interest (ROI) analysis and rib fracture classification test using support vector machine. RESULTS: The statistically significant difference was found between the measured values from fracture and normal ROIs; asymmetry (p < 0.0001), contrast (p < 0.001), and homogeneity (p = 0.022). The rib fracture classifier, trained with the measured values in ROI analysis, detected every rib fracture from chest radiographs used for ROI analysis, but it also classified some unbroken parts of ribs as abnormal parts (8 to 17 line sets; length of each line set, 2.998 +/- 2.652 mm; length of centerlines, 131.067 +/- 29.460 mm). CONCLUSIONS: Our measurement method, which includes a flexible measurement technique for the curved shape of ribs and the proposed shape and texture measures, could discriminate the suspicious regions of ribs for possible rib fractures in chest radiographs.

BACKGROUND: Cytologic diagnosis of pulmonary adenoid cystic carcinoma (AdCC) is frequently challenging and differential diagnosis with small cell carcinoma is often difficult. METHODS: Eleven cytologically diagnosed cases of pulmonary AdCC were collected and reviewed according to fifteen cytomorphologic characteristics: small cell size, cellular uniformity, coarse chromatin, hyperchromasia, distinct nucleolus, frequent nuclear molding, granular cytoplasm, organoid cluster, sheet formation, irregular border of cluster, hyaline globule, hyaline basement membrane material, individual cell necrosis or apoptotic body, and necrotic background. Twenty cases of small cell carcinoma and fifteen cases of non-pulmonary AdCC were also reviewed for the comparison. RESULTS: Statistically significant differences were identified between pulmonary AdCC and small cell carcinoma in fourteen of the fifteen cytomorphologic criteria (differences in sheet formation were not statistically significant). Cellular uniformity, distinct nucleolus, granular cytoplasm, distinct cell border, organoid cluster, hyaline globule, and hyaline basement membrane material were characteristic features of AdCC. Frequent nuclear molding, individual cell necrosis, and necrotic background were almost exclusively identified in small cell carcinoma. Although coarse chromatin and irregular cluster border were observed in both, they favored the diagnosis of small cell carcinoma. Hyaline globules were more frequently seen in non-pulmonary AdCC cases. CONCLUSIONS: Using the fifteen cytomorphologic criteria described by this study, pulmonary AdCC could be successfully distinguished from small cell carcinoma. Such a comprehensive approach to an individual case is recommended for the cytologic diagnosis of pulmonary AdCC.

Dietary sodium intake is considered one of the major causal factors for hypertension. Thus, to control the increase of blood pressure and reduce the risk of hypertension-related clinical complications, a reduction in sodium intake is recommended. The present study aimed at determining the association of dietary sodium intake with meal and snack frequency, snacking time, and taste preference in Korean young adults aged 20-26 years, using a 125-item dish-frequency questionnaire. The mean dietary sodium intakes of men and women were 270.6 mmol/day and 213.1 mmol/day, which were approximately 310% and 245% of the daily sodium intake goal for Korean men and women, respectively. Dietary sodium intake was positively correlated with systolic blood pressure in the total group, and BMI in the total and men-only groups. In the total and men-only groups, those who consumed meals more times per day consumed more dietary sodium, but the number of times they consumed snacks was negatively correlated with dietary sodium intake in the total, men-only, and women-only groups. In addition, those who consumed snacks in the evening consumed more sodium than those who did so in the morning in the men-only group. The sodium intake was also positively associated with preference for salty and sweet taste in the total and women-only groups. Such a high intake of sodium in these young subjects shows that a reduction in sodium intake is important for the prevention of hypertension and related diseases in the future.

PURPOSE: The purpose of this study was to investigate the effects of thermotherapy on gas pain, post-operative resilience, and body temperature discomfort among patients who received laparoscopic myomectomies. METHODS: The experimental group consisted of 62 patients with thermotherapy and the control group consisted of 60 patients. Thermotherapy was applied individually to the experimental group four hours after surgery. The collected data was analyzed using descriptive statistics, t-tests, χ²-tests, and repeated measures of analysis of variance, using IBM SPSS Statistics version 18. RESULTS: The results showed no significant interaction effect between the group and time of measurement in gas-related pain in the experimental group. For gas-related pain, there was significant difference in right shoulder pain at 24 hours (t=-4.222, p=.000), 48 hours (t=-3.688, p=.000), 72 hours (t=-2.250, p=.028), and left at 24 hours (t=-3.727, p=.000), 48 hours (t=-4.150, p=.000), and 72 hours (t=-2.482, p=.016) and both shoulders at 24 hours (t=-2.722, p=.009) and 48 hours (t=-2.525, p=.014). There was no significant difference in epigastric pain, excluding both epigastric pain at 48 hours (t=2.908, p=.005), 72 hours (t=3.010, p=.004), but there was a significant difference in objective body temperature discomfort (t=2.895, p=.008). CONCLUSION: Thermotherapy relieved shoulder gas-related pain and objective body temperature discomfort. It needs to be developed and applied to improve post-operative discomfort in patients with laparoscopic hysterectomies.

Collagen is the major matrix protein in dermis and consists of proline and lysine, which are hydroxylated by prolyl hydroxylase (PH) and lysyl hydroxylase (LH) with cofactors such as vitamin C, oxygen, iron (Fe2+), ketoglutarate and silicon. The collagen degradation is regulated by matrix metalloproteinase-1 (MMP-1), of which is the major collagen-degrading proteinase whereas tissue inhibitors of metalloproteinase-1 (TIMP-1) bind to MMP-1 thereby inhibiting MMP-1 activity. In this study, we investigated the effects of vitamin C, silicon and iron on mRNA, protein expressions of PH, LH, MMP-1 and TIMP-1. The physiological concentrations of vitamin C (0-100 micrometer), silicon (0-50 micrometer) and iron (Fe2+:0-50 micrometer) were treated to human dermal fibroblast cells (HS27 cells) for 3 or 5days. The expression level of mRNA and protein was increased in not only PH but also LH when cells were incubated with vitamin C. A similar increase in LH mRNA or protein expression occurred when cells were incubated with silicon. Our results suggest that treatment of vitamin C and silicon increased mRNA and protein expression of PH and LH in human dermal fibroblast.

To avoid later complication of peritoneal dialysis catheter, it is recommended to delay regular exchange of peritoneal dialysis for about 2-4weeks after insertion of catheter(break-in period). During break-in period some patients need hemodialysis(HD) or other intermittent dialysis. In such cases residual renal function(RRF) can decrease substantially compared with patients who do not need HD during break-in period since RRF is preserved better in CAPD patients than HD patients. This is prospective observational study to examine such an effect of HD during break-in period on residual renal function in CAPD patients. 20 patients who were clinically stable and had been on CAPD since March, 1999 were observed. 6 patients were treated with HD for 1month during break-in period and CAPD thereafter(group A). 14 patients were treated with CAPD without HD(group B). GFR(mean of creatinine and urea clearance of urine) and urine Kt/V urea were measured at start, and 1, 3, 6 months of renal replacement therapy. Covariables analyzed in this study were mean arterial blood pressure, serum albumin, hemoglobin, hematocrit, age, sex, the presence of diabetes mellitus, and peritonitis episode. There was no significant difference in initial RRF, mean arterial blood pressure, serum albumin, hemoglobin, hematocrit, age, sex, and the presence of diabetes mellitus between 2 groups. Initial GFR was a little smaller in group A than group B(45.0+/-10.1 L/week vs. 54.6+/-5.7L/week) which was not statistically significant. GFR after 1, 3 and 6months of dialysis(including 1month of HD in group A) were smaller in group A than B(28.6+/-5.3L/week vs. 54.4+/-5.7L/week, 32.7+/-5.2L/week vs 56.9+/-6.1L/week, 21.0+/-4.1L/week vs 53.6+/-5.4L/week at 1,3,6 months after dialysis in group A and B), which were significant. Urine Kt/V showed same pattern. The change of GFR and urine Kt/V have no correlation with serum albumin, hemoglobin, hematocrit, and change of mean arterial blood pressure and is not affected by sex, and presence of DM or peritonitis. We concluded that HD during break-in period can decrease RRF in CAPD patients, which may not recover after 6months of dialysis. Avoiding HD during break-in period with appropriate preparation can preserve RRF in CAPD patients.

BACKGROUND: This study aimed to investigate the possibility of isolating mesenchymal stem cells (MSCs) from human thigh adipose tissue and the ability of human thigh adipose stem cells (HTASCs) to differentiate into hepatocytes. METHODS: The adipose-derived stem cells (ADSCs) were isolated from thigh adipose tissue. Growth factors, cytokines, and hormones were added to the collagen coated dishes to induce the undifferentiated HTASCs to differentiate into hepatocyte-like cells. To confirm the experimental results, the expression of hepatocyte-specific markers on undifferentiated and differentiated HTASCs was analyzed using reverse transcription polymerase chain reaction and immunocytochemical staining. Differentiation efficiency was evaluated using functional tests such as periodic acid schiff (PAS) staining and detection of the albumin secretion level using enzyme-linked immunosorbent assay (ELISA). RESULTS: The majority of the undifferentiated HTASCs were changed into a more polygonal shape showing tight interactions between the cells. The differentiated HTASCs up-regulated mRNA of hepatocyte markers. Immunocytochemical analysis showed that they were intensely stained with anti-albumin antibody compared with undifferentiated HTASCs. PAS staining showed that HTASCs submitted to the hepatocyte differentiation protocol were able to more specifically store glycogen than undifferentiated HTASCs, displaying a purple color in the cytoplasm of the differentiated HTASCs. ELISA analyses showed that differentiated HTASCs could secrete albumin, which is one of the hepatocyte markers. CONCLUSIONS: MSCs were islolated from human thigh adipose tissue differentiate to heapatocytes. The source of ADSCs is not only abundant abdominal adipose tissue, but also thigh adipose tissue for cell therapy in liver regeneration and tissue regeneration.
