The purpose of this study is to investigate the effect of obese school children's life style habits in order to help school nurse in controlling and preventing the obesity by health education The survey group is extracted from the students of two elementary schools located in Seongnam city Out of 280 children randomly sampled, 102 children were evaluated to be obese and 178 ones to be normal by the standard of the 1985 Korea Pediatric Association Height and Weight Standard Chart The obese children group was compared with the normal one. For this purpose, the surveyors designed a self questionnaire to obtain the description of general background, exercise including play behavior, eating behavior, and family environment of the sampled children. The results are as follows The number of the obese children who took extracurricular physical exercises was significantly (p<0.05) more than that of the normal ones The significantly (p<0.05) more obese children went without a meal to control their weight than the normal ones. In relation to the degree of obesity, the children with the high degree of obesity watched the television significantly (p<0.05) longer than the ones with the mild and the moderate degree of obesity In gender relations, the obese girls participate in outdoorplays and physical exercises significantly (p<0.05) longer and more regularly than the normal ones, while no significant difference was found between the male groups The obese boys had significantly (p<0.05) their mothers occupying in a vocation. Combining television watching habit and mother's vocation of the obese boy, the obesity is resulted from complicated situation It can not be due to the simple absence of the mother, but rather due to the absence of a person responsible for controlling snacking and television watching time of the child Looking at the results, it is necessary for both school and home to actively involve in guiding children and providing an environment to modify life style habits and prevent childhood obesity.

This study searched for the common and different aspects of social community welfare centers and health family support centers for family welfare practice of the community. We also tried to find out the awareness of workers and the performance function for each institution. Through the interviews and review of literature, and comparative analysis of operating status, we looked for the common and different aspects, and the direction of development, which evolved family welfare into the community by way of function and relationships of both institutions. As a result, the participants of this study pursued common purposes. They however made aware of the issues of discrimination about social values and each institution's functions. We suggest that the social community welfare center focuses on individuals and families, in order to integrate the community. A health family support center should play the role to fulfill needs for family welfare according to family life cycle, and have good accessibility for individuals and families in the community.

Purpose: Tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) polymorphism has been suggested to play an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) in obese adults, and known to be a mediator of insulin resistance. In this study, we evaluated the role of TNF-${\alpha}$ promoter polymorphisms and insulin resistance in the development of NAFLD in obese children. Methods: A total of 111 obese children (M:F=74:37; mean age, $11.1{\pm}2.0$ yrs) were included. The children were divided into 3 groups: controls (group I, n=61), children with simple steatosis (group II, n=17), and children with non-alcoholic steatohepatitis (group III, n=33). Serum TNF-${\alpha}$ levels, homeostasis model assessment of insulin resistance (HOMA-IR), and TNF-${\alpha}$ -308 and -238 polymorphisms were evaluated. Results: There were no differences in TNF-${\alpha}$ polymorphism at the -308 or the -238 loci between group I and group II + III ($p$=0.134 and $p$=0.133). The medians of HOMA-IR were significantly different between group I and group II + III ($p$=0.001), with significant difference between group II and group III ($p$=0.007). No difference was observed in the HOMA-IR among the genotypes at the -308 locus ($p$=0.061) or the -238 locus ($p$=0.207) in obese children. Conclusion: TNF-${\alpha}$ promoter polymorphisms at the -308 and -238 loci were not significantly associated with the development of NAFLD in children; nevertheless, insulin resistance remains a likely essential factor in the pathogenesis of NAFLD in obese children, especially in the progression to NASH.

Background: Breast feeding is considered to be mutually beneficial for both mothers and infants, though the effect of lactation problems on development of breast lesions (whether benign or malignant) is not clear. Objectives: This study was conducted to identify possible relations between lactation problems and benign and malignant breast disease. Materials and Methods: 308 patients referred to two referral breast clinics in Tehran, the capital city of IR Iran, between January 2008 and January 2011, were recruited. They were interviewed by a standard questionnaire regarding breast feeding problems. The study population was classified in 3 major groups; breast feeding without any problem, unwillingness to breast feed according to whether mothers' preference not to feed or some breast problems like mastitis, and finally insufficient milk that caused the mothers to feed their babies with formula. Results: Recruiting binary logistic regression method, mother's unwillingness to feed her child by breast milk, and also breast problems such as mastitis and abscess during lactation period showed significant relation with both benign and malignant breast diseases (p value<0.01). Surprisingly, inadequate milk was not associated with any of these conditions. Conclusions: We concluded that lactation problems which involve normal milk drainage from the breast may play an important role in whether the mother wll subsequently develope both benign and malignant pathologies. In contrast in the situation that the production of the milk is not sufficient and there are no intentional or unintentional problems in drainage of the produced milk, future problems would not be more common.

Background: Respiratory viruses play a significant role in the etiology of acute respiratory infections and exacerbation of chronic respiratory illnesses. This study was conducted to identify the epidemiological and clinical characteristics of children with acute viral lower respiratory infections. Methods: This study investigated 1,168 children diagnosed with acute viral lower respiratory tract infections (RTIs) between January 2012 and December 2014. Specimens of respiratory viruses were collected using a nasopharyngeal swab and analyzed by reverse transcriptase polymerase chain reaction. We retrospectively reviewed the medical records and analyzed the clinical features of children hospitalized for acute lower respiratory infections. Results: Respiratory syncytial virus (RSV), the main cause of infection in children aged <5 years, was the most commonly detected pathogen in children with bronchiolitis and pneumonia, and resulted in high proportions of children requiring oxygen treatment and intensive care unit admission. Rhinovirus was preceded by RSV as the second most common cause of bronchiolitis and pneumonia, and was detected most frequently in the children aged ${\geq}6$ years. In addition, asthma was predominantly caused by rhinovirus in children aged ${\geq}6$ years, whereas croup was mostly caused by parainfluenza virus in those aged <5 years. Rhinovirus infection (p<0.001) and history of asthma (p=0.049) were identified as significant risk factors for readmission within a month. Conclusion: We identified the epidemiological and clinical characteristics of respiratory viruses in children with acute lower respiratory infections during the last 3 years. Our findings may provide useful clinical insight to comprehend the acute viral lower RTIs in children.

This study was conducted to reduce sodium (Na) intake and to establish healthy dietary lifestyles of children. To achieve these goals, we searched, collected, and analyzed the materials related to the Na education, based on which the research personnel-professors and graduate students in nutrition and child education and elementary school teachers discussed to figure out major topics, objectives, and detailed contents and activities appropriate for Na intake reduction. Also a survey was done on the sodium intake and nutrition knowledge of the elementary students. We also organized an advisory committee composed of 15 professionals in related fields to discuss the adequacy and validity of the specific contents. Finally, we systematically organized the contents and developed children's textbooks and teacher's guidebooks. Considering the different cognitive development stages of junior and senior elementary students, we developed two different textbooks for each of them which are easy to read and understand, fun to play with lots of activities, and designed to practice into daily life. The contents cover three major topics-the concept of Na, Na in food, Na in life and are composed of 6 units in total. To help teachers understand and instruct, teacher's guidebook contains an overview of the education, specific information and practical guidelines for each class. We developed these education materials with the aim of lowering children's Na consumption and eventually promoting their health welfare; hopefully we expect these materials would be useful for children's nutritional education in the field.
