Objectives: The objective of the study was to investigate the use of dental hygiene devices in Korean adolescents. Methods: The study subjects were 70,362 adolescents in 800 schools who completed the 2015 Korean Youth Risk Behavior Web-based survey. Dependent variables included usage of dental floss, interdental brushes and mouthwash solutions. Independent variables included demographic characteristics of the subjects, health state and behaviors, and oral health behaviors and experience of oral diseases. Results: The related factors of usage of dental hygiene devices included gender, where females showed higher usage (OR=1.10) compared to males, father and mother's level of education where usage was higher in above university graduates (OR=1.20, OR=1.14) compared to less than high school graduation, economic status where usage was higherin high and middle (OR=1.93, OR=1.26) compared to low, vigorous physical activity where usage was higher in those who responded yes (OR=1.35) compared to no, subjective weight recognition where usage was higher in normal (OR=1.07) compared to under weight, sleep time where usage was higher in enough (OR=1.12) compared to not enough, number of toothbrushing (day) where usage was higher in 2 times or over 3 times (OR=1.35, OR=1.75) compared to below 1, oral health education experience (OR=1.10), sealant experience (OR=1.17) and scaling experience (OR=1.45) where usage was higher in those who responded yes compared to no, school where usage was lower in high school (OR=0.64) compared to middle school, residential type where usage was lower in rural area (OR=0.74) compared to metropolitan area, living form where usage was lower in other (OR=0.77), compared to with family, smoking (OR=0.93), and alcohol drinking (OR=0.90) where usage was lower in those who engage in the activities compared to those who didn't, BMI where usage was lower in normal (OR=0.87) and over weight (OR=0.98) compared to under weight. Conclusions: To expand the use of dental hygiene devices in the adolescents, it is necessary to improve the continuing education program for need and motivation of dental hygiene device usage.

Objectives：Body image is closely related to self-esteem and weight-control related behaviors. In particular, relationship between two factors would be stronger in female adolescents. False recognition on body image and weight can be a risk factor of eating disorder, depression, and suicidal ideation. This study aimed to examine the effects of body image and eating disorders on developing depressive symptoms and suicidal ideation in female adolescents. Methods：Two hundred thirty nine students of a Girls' Commercial High School in Seoul were recruited. Eating Attitude Test for Korean Adolescents, Self-Esteem Scales, Impulsiveness Scale, Beck's Depression Inventory and Beck's Suicidal Ideation Scale were used to measure eating attitude and severity of psychiatric symptoms. Results：Among 239 subjects, the estimated risk group of eating disorders was 10%(n=24). They experienced more depressive symptoms than the control group. The bigger discrepancy in current and ideal body mass index was significantly related with higher depressive mood, suicidal idea, abnormal eating habits and lower self-esteem. Discrepancy between current and idea BMI was the most meaningful predictive factor about depression and suicidal thoughts by linear regression analysis. Conclusion：In spite of normal weight range of enrolled subjects, they experienced significant depressive mood, suicide thoughts and lower self-esteem associated with the discrepancy of their own subjective body image and current body mass index. Hence educational approach regarding normal body image and healthy weight control is needed for their mental health and preventing eating disorder.

The visual attention mechanism includes 2 attention models, the bottom-up (B-U) and the top-down (T-D), the physiology of which have not yet been accurately described. In this paper, the visual attention mechanism is regarded as a Bayesian fusion process, and a visual attention model based on particle filter is proposed. Under certain particular assumed conditions, a calculation formula of Bayesian posterior probability is deduced. The visual attention fusion process based on the particle filter is realized through importance sampling, particle weight updating, and resampling, and visual attention is finally determined by the particle distribution state. The test results of multigroup images show that the calculation result of this model has better subjective and objective effects than that of other models.

The present clinical trial was performed to evaluate the anthelminthic effect and tolerance of Oxantel pamoate, a new antiwhipworm agent, in the treatment of T. trichiurus infection. Oxantel pamoate oral suspension was administered as a sing1e dose of 10 mg per kg. body weight to a total of 46 T. trichiurus infected cases selected out of 64 positives, by examining 89 fecal specimens collected from the soldiers and in-patients of xx Armed Forces General Hospital. For the evaluation, the negative conversion rate (cure rate) and the egg reduction rate were assessed 22 days after the treatment. The result obtained were as follows: 1. The prevalence rate of T. trichiurus infection in this study was 71.9%, while the mean E.P.G. of 46 treated cases was 126. 2. The egg negative conversion rate was 91.3%, and 98.4% of egg reduction rate was obtained. 3. From the observation of 107 worms expelled during 3 consecutive days after the treatment, it was known that sex ratio of male and female was about 1 : 2 and that average worm burden per capita was 2.3. 4. In all treated cases, the medication was readily accepted and well tolerated. On the hemograms, urinalysis and liver function tests, no significant differences were noted before and after the drug administration. There was also no detectable objective and subjective side effect.

Purpose: The purpose of this study was to determine the effects of self-care program using Short message service (SMS), e-mail, or telephone call on self-care compliance and nutritional status in maintenance of hemodialysis patient. Methods: Nonequivalent pretest-posttest control experimental design was used. Ninety-six patients were allocated to control (n=24), SMS (n=24), e-mail (n=24), or telephone (n=24) group from four hospitals. Experimental groups received self-care program about hemodialysis diet, drug administration, exercise, and fistula care by SMS, e-mail, or telephone call respectively at 3 times a week for 4 weeks. Results: Subjective self-care compliance, and objective self-care compliance including interdialytic weight of SMS and telephone groups were significantly increased than those of control groups. However, nutritional status of SMS and e-mail groups were significantly improved than those of control groups in albumin and protein level. Conclusion: Self-care program using SMS and telephone call were effective on promoting self-care compliance, while SMS and e-mail were effective on improving nutritional status. The pop-up remaining effect and easy accessible effect of SMS message in busy daily life was considered as an alarm to control fluid and diet.

Objectives : The purpose of the study is to investigate the effects of bite force by gender and physical features. Methods : A self-reported questionnaire was filled out by 212 college students in Chungnam province from October to December, 2013. The questionnaire consisted of oral health condition. The bite force of the first molar teeth was measured. Results : Males showed the greater bite force than females(p<0.001). Those who had temporomandibular joint(TMJ) disorder suffered from mouth opening difficulty and weaker bite force than those who had not(p<0.05). Those who had malocclusion showed weaker bite force (p<0.01). Those who had a habit of chewing gums tended to have greater bite force than those who had not(p<0.05). The bite force was correlated with height(r=0.309), weight(r=0.345), and BMI(r=0.249)(p<0.01). Conclusions : Males showed greater bite force than females. The temporomandibular joint (TMJ) disorder, subjective malocclusion, and eating habit also affected the bite force.

The purpose of this study was 1) to determine physical properties, and subjective evaluation of sensation of sports socks with various type of fiber content and fabric structure, and 2) to develop regression equations for predicting each sensation from physical properties of socks. Thirty healthy male students participated in the wear test with ten replications. The ANOVA, Duncans multiple test, and multiple regression, and paired-t test were used in the statistical analysis, using an SAS package. The results of this study are as follows: 1. 100% cotton socks had higher absorbency and wickability among five different socks. Comfort sensation, tactile sensation and fit sensation of socks were significantly influenced by types of fiber content. People felt that polypropylene socks were less comfortable & slightly tighter, and cotton socks were drier than the other socks. Terry socks were warmer than single jersey socks. 2. The results of the regression analysis showed that tactile sensation of socks after exercise can be predicted from the cube of moisture permeability($R^2$=0.99), and fit sensation can be predicted from drop absorbency, moisture permeability, wickability in wale and weight($R^2$=-0.98).

This study was conducted to investigate the correlation between frequency of high-caffeine energy drink intake in adolescents and their mental health status using data from the Korean adolescent health behaviors online survey (2014-15). Mental health was classified by the five categories: Perception of stress (PS), Insufficient relief of fatigue after sleep (IRFS), Experience of sadness despair (SD), Suicidal ideation (SI), and Subjective unhappiness (SU). Regarding general characteristics, higher age, height, and body weight of subjects were associated with higher frequency of high-caffeine energy drink (HCED) intake (p< .0001). In the OR analysis, when the lowest group (${\leq}2/wk$) and highest group ($1{\geq}day$) were compared, the highest group showed significantly higher OR in all five categories of mental health. According to gender, males did not show better PS, SD, and SI than females who had a high frequency of HCED (p for trend<.0001). According to school level, middle school students showed a higher risk rate than high school students in PS, IRFS, and SD (p for trend< .0001). Based on the above results, higher frequency of HCED intake among adolescents was associated with more adverse effects on mental health.

Purpose: The purpose of this study was to identify the effects of nutritional education program (NEP) on nausea and vomiting, anorexia, food intake, and nutritional status among GI cancer patients undergoing chemotherapy. Methods: A nonequivalent, non-synchronized posttest design was used. Study subjects were conveniently selected 30 patients (15 subjects for each group) who were undergoing chemotherapy. The subjects of the experimental group received NEP which consisted of 2 educations and 1 counselling while they were hospitalized, and telephone counselling with nutritional supports after discharge for four times. Results: The score of anorexia was lower and the amount of food intake was higher in the experimental group than those of the control group. However, there were no significant differences in levels of nausea and vomiting, weight, hemoglobin, albumin, and total protein level between the experimental and the control group. Conclusion: The findings demonstrate that the NEP was effective in alleviating anorexia and improving subjective food intake of GI cancer patients undergoing chemotherapy. These findings suggest that NEP can be a useful nursing intervention for preventing nutritional disorders for patients with GI cancer after chemotherapy.
