Study population was described at the previously published paper(23). Body Mass Index of 10751, 5th grade students from nation-wide were calculated . From this distribution lowest 10% and highest 10% were selected as group 1 and group 5, respectively. In this paper, between group 1 and group 5 anthropometric data, demographic data and other health related factors were compared. 1) Using Japanese criteria for obesity, the prevalence for obesity at 5 th grade was 5.8% at nation wide and 7.8% at urban area. 2) The proportion of students who skipped breakfasts everyday was 5.8% of whole student surveyed and 8.4% for group 5. The proportion of students who took medicine for health was 29.4% for group and 22.5% for group 5. 3) The students who are at group 5 had larger height and weight velocity than other groups. Group 5 had large increase of BMI by increasing grade, but group 1 had almost no change. 4) In physical fitness examination, group 3 who mean BMI was in the highest class than other groups 5 was in low class.

BACKGROUND/OBJECTIVES: Rheumatoid arthritis (RA) is associated with an excess mortality from cardiovascular disease which is likely attributed to an atherogenic lipid profile. Among nutritional factors vitamin K has been recently focused as a pivotal nutrient in improvement of lipid related markers. Thus, this study was designed to determine the effects of vitamin K on lipid profile in this disease. SUBJECTS/METHODS: Fifty eight patients with definitive RA were participated in the present double blind placebo controlled study. They were randomly allocated into two groups to receive vitamin $K_1$ as phylloquinone [10 mg/day] (n = 30) or placebo pills (n = 28), for eight weeks. In order to control the effects of probable confounders dietary intakes, anthropometric measurements including weight and height, clinical status using disease activity score-28 (DAS-28), physical activity and anxiety status were evaluated at baseline. Moreover, serum levels of lipid related markers including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and triglyceride (TG) were measured at baseline and at the end of intervention. RESULTS: There were no significant differences between the two groups regarding any of the baseline characteristics. After adjusting for some relevant confounders, in comparison between two groups, we observed no significant changes in lipid related markers at the end of intervention. Also, there was no significant difference between before and after intervention values within groups (P > 0.05). CONCLUSIONS: Function of vitamin $K_1$ in lipid profile modification remains still controversial. This study showed that vitamin $K_1$ has no effect on lipid profile in women with rheumatoid arthritis. Further studies with a longer follow-up are required to determine the effects of vitamin K on atherogenic lipid profile.

Purpose: The study purposes were to explore school nurses' experience, perceived barriers, and education needs in diabetes management at school. Methods: This study was a cross sectional study and the study participants were recruited conveniently at continuing education seminars for school nurses at Incheon Metropolitan City. Results: Data for 101 school nurses were analyzed. The nurses were all women and their mean age was $46.9{\pm}9.3$ years. About 66% of them had experience with children with diabetes at school. The school nurses reported that 74.6% of the students tested their blood glucose by themselves, the school clinic was the most common place for blood glucose tests (47.8%) and insulin injections (50.8%) and the nurses knew students' diagnosis through the student health survey (58.2%). About half of the nurses (53.7%) reported that glucagon should be available at school and 49.2% were willing to inject glucagon when necessary. The most frequently reported barrier in diabetes management was role confusion ($6.0{\pm}1.3$) and the most common educational need was emergency responses ($5.9{\pm}1.4$). Conclusions: School health policy for diabetes management and diabetes resources are necessary to minimize role confusion of school nurses, improve emergency response, and facilitate health promotion activities in diabetes management.

Two rare cases of human infection with parvum (dwarf) type of Diphyllobothnum Iatum [syn. D. panpum (Stephens, 1908)], were discovered in Korea. The first case was a 46-year old housewife, from whom a kind of pseudophyllidean tapeworm eggs was detected in the feces. She was treated with praziquantel and purged, and a complete strobila with scolex, 120 cm in total length, was recovered. She recalled that she had eaten raw trouts at a raw-fish restaurant near the Chungju Lake. Another patient was a 22-year old medical student (male), who used to eat raw sea-foods. He discovered a chain of tapeworm proglottids, 15 cm in length, discharged spontaneously in his stool and brought it for identification. The worms from the two cases were compatible with D. pan)urn (Stephens, 1908) of which the taxonomic significance has long been questioned. After a detailed morphological study and review of literature, we designated the worms as D. datum prom type. This is the first report on the occurrence of this rare type of D. lotunl infection in Korea.

Purpose: The purpose of this study was to identify international students' use of university health centers by individual characteristics and seasons. Methods: This was a retrospective descriptive study using data obtained from the electronic record system of one university health center. The study participants were international undergraduate students who registered for any of two semesters between March 1, 2014 and February 28, 2015 and visited the university health center during their registration period. Results: The most common reasons for visits were problems of head, eye, nose and throat systems, followed by respiratory system. Their visits mostly occurred in the fall and spring. The most frequently used services were distribution of oral medication followed by wound treatment. The number of visits per individual was statistically different by gender (u=-3.307, p=.001), but not by their major (${\chi}^2$=.543, p=0.762) or nationality (${\chi}^2$=5.518, p=.271). Conclusion: Further study is necessary to better define health needs and related factors for this unique population. The electronic record system provides great opportunities in development and application of need based health services for international students and for research in this area.

In sleep monitoring system, polysomnography (PSG) is the gold-standard but previous studies revealed that attaching numerous amount of sensors disturb sleep during the test which is the fundamental disadvantage of PSG. We suggest an unconstrained rapid-eye-movement (REM) sleep monitoring method measured with polyvinylidene (PVDF) film-based sensor for the normal and the obstructive sleep apnea (OSA) patients. Nine normal subjects and seventeen OSA patients have participated in the study. During REM sleep, rate and variability of respiration are known to be greater than in other sleep stages. Based on this phenomena, respiratory signals of participants were unconstrainedly measured using the PVDF-based sensor with the PSG and REM sleep were extracted from the average rate and variability of respiration. In epoch-by-epoch REM sleep detection, proposed method classified REM sleep with an average sensitivity of 72.3%, specificity of 92.5%, accuracy of 88.9%, and kappa statistic of 0.60 compared to the results of PSG. Student's t-test showed no significant difference between the results of normal and OSA group. This method is potentially applicable to REM sleep detection in homing environment or ambulatory monitoring.

Purpose: The aim of this study was to evaluate the relationship between maternal periodontal disease and the health status of newborns using Apgar scores. Methods: One hundred pregnant women with periodontal disease were included in the case series and 100 pregnant women without periodontal disease were placed in the control group, respectively. The periodontal parameters of bleeding on probing (BOP), clinical attachment loss (CAL), probing depth (PD), birth weight, and Apgar scores were recorded in both groups. T-tests and Pearson's correlation coefficient were used to determine the birth weight odds ratio to analyze the relationship between the periodontal parameters of BOP, CAL, and PD on the one hand and an Apgar score of less than 7. An unpaired Student's t-test was used to analyze differences in means between the case and control groups using SPSS ver. 13. Results: The means of the ages, periodontal pocket depths, attachment loss, areas with BOP, Apgar score in the first 5 minutes and infant birth weight exhibited statistically significant differences between the case and control groups. The ratio of an Apgar score of <7 to periodontal disease was 3.14; the ratio of low birth weight risk in mothers with periodontal disease to that in mothers without periodontal disease was 2.74. Pearson's correlation coefficient revealed a significant correlation between the infant birth weight and BOP, CAL, and PD of the mother. In addition, there was a significant correlation between the Apgar score and BOP, CAL, and PD and also between the Apgar score and infant birth weight. Conclusions: The results of this study showed a significant relationship between periodontal disease and infant birth weight; in addition, there was a significant relationship between the periodontal indexes of BOP, CAL, and PD on the one hand and the Apgar score on the other.

Cutaneous leishmaniasis (CL) is a parasitic disease characterized by single or multiple ulcerations. Secondary bacterial infections are one of the complications that can increase the tissue destruction and the resulting scar. To better determine the incidence of real secondary bacterial infections in CL, we designed the current study. This was a cross-sectional study performed in Skin Diseases and Leishmaniasis Research Centre, Isfahan, Iran. A total of 1,255 patients with confirmed CL enrolled in the study. Sterile swaps were achieved for ulcer exudates and scraping was used for non-ulcerated lesions. All samples were transferred to tryptic soy broth medium. After 24 hr of incubation at $37^{\circ}C$ they were transferred to eosin methylene blue agar (EMB) and blood agar. Laboratory tests were used to determine the species of bacteria. Among 1,255 confirmed CL patients, 274 (21.8%) had positive cultures for secondary bacterial infections. The bacteria isolated from the lesions were Staphylococcus aureus in 190 cases (69.3%), coagulase negative Staphylococcus in 63 cases (23.0%), E. coli in 10 cases (3.6%), Proteus sp. in 6 cases (2.2%), and Klebsiella sp. in 5 cases (1.9%). The results show that the overall incidence of secondary bacterial infections in the lesions of CL was 21.8%, considerably high. The incidence of secondary bacterial infections was significantly higher in ulcerated lesions compared with non-ulcerated lesions.

Background: This study evaluated the efficacy of virtual reality (VR) distraction and counter-stimulation (CS) on dental anxiety and pain perception to local anesthesia in children. Methods: A prospective, randomized, single-blinded interventional clinical trial with a parallel design was used. Seventy children 7-11 years old who required local anesthesia (LA) for pulp therapy or tooth extraction were recruited and allocated to two groups with equal distribution based on the intervention. Group CS (n = 35) received CS and Group VR (n = 35) received VR distraction with ANTVR glasses. Anxiety levels (using pulse rate) were evaluated before, during, and after administration of local anesthesia, while pain perception was assessed immediately after the injection. Wong-Baker faces pain-rating scale (WBFPS), visual analog scale (VAS), and Venham's clinical anxiety rating scale (VCARS) were used for pain evaluation. Student's t-test was used to test the mean difference between groups, and repeated measures ANOVA was used to test the mean difference of pulse rates. Results: Significant differences in mean pulse rates were observed in both groups, while children in the VR group had a higher reduction (P < 0.05), and the mean VCARS scores were significant in the VR group (P < 0.05). Mean WBFPS scores showed less pain perception to LA needle prick in the CS group while the same change was observed in the VR group with VAS scores. Conclusions: VR distraction is better than CS for reducing anxiety to injection in children undergoing extraction and pulpectomy.
