Objectives: This study was performed to identify the current barriers of obesity management for children using Community Child Care Centers and their caregivers (parents and teachers working in the Centers). Further, this study explored the possibility of utilizing a mobile phone application for tailored obesity prevention and management programs to overcome the current difficulties associated with children's obesity management. Methods: The qualitative data were collected through in-depth interviews with 20 obese and overweight children or children who wanted to participate in this study using Community Child Care Centers, 12 teachers working at the Centers, and a focus group interview with five parents of children using the Centers. Data were analyzed with a thematic approach categorizing themes and sub-themes based on the transcripts. Results: The current barriers of obesity management of obese and overweight children using Community Child Care Centers were lack of self-directed motivation regarding obesity management (chronic obesity-induced lifestyles and reduced self-confidence due to stigma) and lack of support from households and Community Child Care Centers (latchkey child, inconsistency in dietary guidance between the Center and household, repetitive pressure to eat, and absence of regular nutrition education). Mobile phone applications may have potential to overcome the current barriers by providing handy and interesting obesity management based on visual media (real-time tracking of lifestyles using behavior records and social support using gamification), environmental support (supplementation of parental care and network-based education between the Community Child Care Center and household), and individualized intervention (encouragement of tailored and gradual changes in eating habits and tailored goal setting). It is predicted that the real-time mobile phone program will provide information for improving nutritional knowledge and behavioral skills as well as lead to sustainable children's coping strategies regarding obesity management. In addition, it is expected that environmental factors may be improved by network-based education between the Community Child Care Centers and households using the characteristics of mobile phones, which are free from space and time constraints. Conclusions: The tailored education program for children using Community Child Care Centers based on mobile phones may prevent and reduce childhood obesity by overcoming the current barriers of obesity management for children, providing environmental and individualized support to promote healthy lifestyles and quality of life in the future.

Objectives: The purpose of this study was to investigate how clinical nutrition services is provided at a long term care hospital in Korea and to investigate job satisfaction levels of the clinical dietitians. Methods: Survey questionnaire was sent to dietitians working at a long term care hospital in Korea. The participating hospitals (n=240) were randomly selected from 1,180 long- term care hospitals using a stratified sampling method. A total of 134 long term care hospital s and 223 dietitians completed the survey of clinical nutrition service s and job satisfaction questionnaires The job satisfaction questionnaire included 27 job satisfaction questions on task, stability vision, working conditions, and relationship areas. Results: The average nutritional screening rate was 17.9% and the rate of computerized nutritional screening system was 9.7% in the participating hospitals. Nutritional intervention rate was only 3.2% of all patients. KOIHA (Korea Institute for Healthcare Accreditation) accreditated hospitals showed only 50% performance rate of nutrition service evaluation area. This shows that after achieving KOIHA accredition, many hospitals do not emphasize the performance of nutritional services. The job satisfaction scores in all four areas ranged from 2/5 to 3/5, implying generally low job satisfaction level in hospital dietitians. Linear regression analysis results showed that the "hospital adequacy grade" type was a significant predictor of job satisfaction level for two areas (working conditions & relationship). Conclusions: There is a need to provide proper standardized clinical nutrition services as a primary treatment and we observed large variations in the quality of nutritional service s in long term care hospitals. Therefore, government and local hospitals have to work on implementing nutritional programs and policies for improved service and care.

In this article, the writer attempted to study the followings: (1) mother's knowledge of milk feeding (including method of sterilization, formula and feeding) (2) reasons of artificial feeding (3) how much mothers are concerned about their artificial feeding infants (4) condition of growth and development of artificial feeding infants. As the object of study, 96 mothers with artificial feeding infants, who had consulted dep't of pediatrics of two Hospitals in Seoul (Korea Hospital and Med. College Woo Suk Hospital, Korea Uni.) and well baby clinic of the two Health Centers (Sung Dong and Dongdaemoon), were randomly sampled. The data were treated by the statistic method of chi-square and percentage, and come to the following conclusion. 1. Knowledge of milk feeding Sterilization: 70 percentages of mothers know about the milk sterilization (including bottle, nipple and instrument), but 55 percentages of them do not know the nipple sterilization correctly. Formula: 69 percentages of mothers follow the indicator or in accordance with doctor's directions, but 31 percentages do at their option by reasons that the baby often coughs up the milk, the baby is too small, the baby often has digestive troubles, or the baby grow fleshy heavily etc, except family economic problems. Feeding: only half of mothers know the correct feeding method, especially they do not know how to determine the heat degree of milk and how to bubble up the baby correctly. They just do feeding according to the accepted usages. 2. Reasons of artificial feeding Of the reasons of artificial feeding, 18 percentages were caused by infants and 82 percentages by mothers. Most of the reasons are mainly due to the lack of breast milk and sufficient supply of nourishments rather than mother's deficiency or mother's abnormality. 3. Mother's concern for artificial feeding infants Mothers who are sharply concerned for their artificial feeding baby's growth and development: 63%, mothers who made the baby (artificial feeding infant) routine vaccinated: 81%, mothers who ear anxious about the baby's future personality forming : 68%, mothers who care about the baby's condition of nourishment; 60%, mothers who are anxious about tile selection of baby's food; 54%. 4. The growth and development of artificial feeding infants compared with Korean average infants. The artificial feeding infants are above the Korean average infants in stature by 1.21 centimeters and in weight by 0.3 kilograms. Conclusion: It has been said that there is no better food for infant than the breast milk. However, the artificial feeding has been used for the supplement of nourishments and as substitute food for the breast milk. And this artificial feeding could give the married women the chance to act in society and more opportunity to develop themselves and to work for others at home and other fields. Considering these advantages, artificial feeding should not be exclusive, but preferably should be more improved and inquired positively. And even in artificial feeding, what is most important is that mothers should recognize the requirement and need of artificial feeding clearly and correctly, and they should be accustomed to the correct knowledge and skills of artificial feeding in order to practice it appropriately. In some degree, they should be properly trained in school education process.

This study aims to examine what influence sanitary education have on sanitary knowledge in terms of frequency, necessity, degree of satisfaction, degree of understanding, and applicability, and what influence sanitary knowledge of cooks has on sanitary management performance, targeting cooks employed by contracted foodservices. For this purpose, we conducted a survey of 31 contracted foodservice companies catering to factories, colleges, hospitals, offices, government offices located in Busan & Gyeongnam region from October 1 to 15, 2012. A total of 320 copies of questionnaire were handed out, and 302 copies (94.3%) were retrieved and 289 ones (90.3%), to the exclusion of 13 wrongly written ones, were used in the final analysis. The analysis result showed that the more necessity of sanitary education cooks perceived; the higher satisfaction with the sanitary education they felt; the higher applicability of the sanitary education, the higher level of sanitary knowledge they got. It was revealed that the degree of satisfaction with the sanitary education had the strongest influence on the improvement of sanitary knowledge compared to the other factors. In addition, It was shown that as the level of sanitary knowledge of cooks improved, their sanitary management performance also got better.

Boesenbergia pandurata (Roxb.) Schltr. has been reported to possess anti-oxidative and anti-inflammatory properties. The aim of this study was to investigate the effect of Boesenbergia pandurata extract (BPE) in a high-fat diet (HFD)-induced obese mice model. C57BL/6J mice were fed with either the high-fat diet or a 0.5% BPE-supplemented HFD for 8 weeks. The BPE-containing HFD significantly reduced body weight gain and the accumulation of visceral fat mass in mice model without altering the amount of food intake. Moreover, mice fed with BPE-containing HFD had lower concentrations of lipids in their blood, lower hepatic lipid accumulation, and lower serum leptin levels compared with the HFD-fed mice. RT-PCR analysis showed that the expression levels of peroxisome proliferators-activated receptor ${\gamma}2$ ($PPAR{\gamma}2$) and CCAT/enhancer binding protein ${\alpha}$ ($C/EBP{\alpha}$) genes in the epididymal fat tissue of mice fed the BPE-containing HFD increased 1.16- and 1.30-fold, respectively, compared to mice fed HFD only. In conclusion, BPE attenuated visceral fat accumulation and improved dyslipidemia in a mice model with HFD-induced obesity.

In this study, the influence of mixed starter compositions using Saccharomyces cerevisiae and three mixed probiotics, including Bifidobacterium longum, Enterococcus faecium, and Lactobacillus acidophilus on sourdough and bread preparation was examined. The following probiotic and yeast mixing ratios were used: Exp. 1, probiotics:yeast=2.0:0.1; Exp. 2, 1.5:0.1; Exp. 3, 1.0:0.1 (g/g). Starters for the sourdough preparation were incubated separately for 15 hr, combined, then further incubated for 10 hr. Exp 2 resulted in an increase in the numbers of probiotics and yeast in sourdough by 100 times but reduced pH. This is also reflected by the extent of the acidity increase in sourdough produced in Exp. 2. Among the three groups, bread volume and crumb elongation increased in Exp. 2, but crumb fineness and aroma compounds were not significantly different. In a sensory evaluation, flavor, taste, and overall acceptance for the sourdough produced in Exp. 2 improved markedly.

Obesity is considered a mild inflammatory state, and the secretion of inflammation-related cytokines rises as adipose tissue expands. Inflammatory cytokines, including tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interlukin 6 (IL-6) and monocyte-chemoattractant protein 1 (MCP-1), are modulated by adipose tissue and known to play an important role in insulin resistance which is the common characteristics of obesity related disorders. In this study we analyzed the effects of Sasa borealis leaves extract on inflammatory cytokines and insulin resistance in diet induced obese C57/BL6J mice. The obese state was induced by a high fat diet for 20 weeks and then the mice were divided into two groups; obese control group (OBC, n = 7) and experimental group (OB-SBE, n = 7). The OBC group was fed a high fat diet and the OB-SBE group was fed a high fat diet containing 5% Sasa borealis leaves extract (SBE) for 12 weeks. We also used mice fed a standard diet as a normal control (NC, n = 7). The body weight and adipose tissue weight in the OB group were significantly higher than those in the NC group. The effects of the high fat diet were reduced by SBE treatments, and the body weight and adipose tissue deposition in the OB-SBE group were significantly decreased compared to the OBC group. The OBC group showed higher serum glucose and insulin levels which resulted in a significant increase of incremental area under the curve (IAUC) and HOMA-IR than the NC group. Also, serum leptin, TNF-${\alpha}$, and IL-6 levels were significantly higher in the OBC group than in the NC group. In contrast, the OB-SBE group showed a reversal in the metabolic defects, including a decrease in glucose, insulin, IAUC, HOMA-IR, TNF-${\alpha}$, IL-6 and leptin levels. These results suggest that BSE can suppress increased weight gain and/or fat deposition induced by a high fat diet and theses effects are accompanied by modulation of the inflammatory cytokines, TNF-${\alpha}$ and IL-6 secretion resulting in improved insulin resistance.

BACKGROUND: Because dried herbal medicines have many active ingredients, it is not easy to determine the residue amount after extraction, partition and clean up of pesticides from them. Especially, liquid-liquid partition method is consuming many times and solvents. Macroporous diatomaceous earth(MDE) column was used to replace the separatory funnel for liquid-liquid extraction with dichloromethane to analyze the endosulfan and its metabolite. METHODS AND RESULTS: The residue analysis method using MDE column instead of liquid-liquid partition for determining insecticide endosulfan and its metabolite in 4 dried herbal medicines was developed by GC/MS. As a result, the recovery rates of the pesticides in 4 herbal medicines were ranged from 80.3 to 93.5% for ${\alpha}$-endosulfan, from 81.0 to 100.3% for ${\beta}$-endosulfan and from 80.6 to 95.6% for endosulfan sulfate, respectively. The coefficients of variation for triplicate were ranged from 1.1 to 3.4%. CONCLUSION: The improved methods are more ecofriendly, safer, faster and less laborious than conventional method by KFDA.

The objective of this study was to evaluate microbiological Quality of HACCP application in elementary school foodservice operations. Microbiological Quality of utensils and non-heated foods such as salad was measured two times at five elementary schools in Daegu. The two experimentations differed in that after the first experimentation employees were educated and trained on HACCP based sanitation standards with a goal of improving microbiological Quality of foodservice. Microbiological Quality, time, and temperature were evaluated at three critical control points (CCPs)： washing and disinfecting, personal hygiene and non-cross contamination. Micro-biological Quality was assessed using 3M petrifilm to measure total plate count and coliform group. The first experimentation showed low microbiological Quality due to cross contamination of utensils and cooking gloves; high microbiological count of the garlic, powdered red pepper, and ginger; and not thoroughly washing and disinfecting vegetables. In the second experimentation, microbiological Quality was greatly improved by washing and thoroughly disinfecting raw ingredients and utensils, and using good personal hygiene. However, microbiological Quality of seasonings was still low. Immediate corrective actions were required in one of the foodservice operations that was assessed. These results strongly suggest that foodservice operations should address non-heated food Quality. It is essential to measure microbiological Quality regularly and continually train and retrain employees on hand washing and disinfecting raw ingredients. Further studies are needed to determine whether pathogens are present in raw vegetables and seasonings.

To visually identify the spoilage of chicken breasts, a three layered freshness indicator consisting of PET/bromocresol green (BCG)-ethylene vinyl acetate (EVA)-acetic acid (AA) composite layer/porous substrates was successfully prepared and their performance were simulated at 20% of $CO_2$ and 4 different trimethylamine (TMA) concentrations to evaluate color change at minimal spoilage level. The visibility and range of color changes of the as-prepared indicators responding to TMA concentration as a simulant were strongly dependent on the concentrations of BCG and AA. As the BCG content increased, the visibility of color change in the freshness indicators was apparently improved and the range of color change could be controlled by contents of AA. Among the as-prepared freshness indicators, 'G0.12_A0.5' which consisting 0.12g of BCG and 0.5g of AA was selected as an optimum composition due to the highest visibility at TMA 20 mg% corresponding to the minimal spoilage level. The color of the indicator changed from yellow to green for spoilage indication of chicken breast, which could be easily seen with the naked eyes and well consistent with the simulation results. It is expected that our developed freshness indicator can be useful in monitoring various food freshness and quality.
