Objectives While Temporomandibular disorders (TMD) is highly prevalent in Korea, studies examining its Korean medical treatment are currently lacking. The aim of this study was to assess current Korean medical treatment practice patterns for TMD. Methods A preliminary questionnaire was developed to investigate current practice patterns of TMD treatment and underwent further revision through external review. The final questionnaire was distributed as a web-based survey to 18,289 potential respondents by email. Results The response rate was 2.23%. Most participants replied that they received multiple Korean medicine interventions for TMD treatment consisting of such methods as acupuncture, chuna manipulation, electroacupuncture. The percentage of treatment services among uncovered services, which need to be covered by national health insurance was high in the order of pharmacopuncture, chuna manipulation, and herbal medicine. The most commonly used diagnostic examination tools for TMD was Physical examination and next was Imaging diagnosis. The frequency of TMD treatment was the highest at 2~3 times per week (76%) and the period was from 4 to 12 weeks (63%). Conclusions This survey study helps determine current practice patterns of TMD, and recognizes the need for use of diagnostic devices in TMD treatment. These results are further anticipated to provide basic data for clinical practice guide lines (CPGs).

In a globalization and information society in the 21st century, the emphasis of education is on producing people who can create intellectual value. To meet the purpose in mathematics education, students should be taught to be able to understand basic logics and principles and exchange mathematical information each other. Also they had better be guided to study on their own at home in an effective way. In reality, however, most of the home study does not go beyond confirming the same homework. It is very difficult for students to plan systematic preparation and review of their lessons and study on their own. Moreover there seems to be no integration between the lessons students receive at school and in private classes. Therefore the need for more systematic home study in relation to school lessons is high to maximize the teaming effect. Studying through Web has little restriction in terms of time and space. Students can collect useful information inexpensively and share their learning assignment with each other. But mathematics education through Web has not yet been developed in such a way as to see a positive result from it. This research intends to develop a web site where students can study mathematics systematically in a self-guided way. The research methods applied included survey, student discussion and online home study. The questionnaires were designed to figure out students'and parents'changes in their concept of mathematics home study. The research also tried to look for ways to cut down the burden of expensive private lessons in mathematics. The student discussions were made up of problem-making and problem-solving. The discussion procedure was analysed so as to check if students used their creativity while they were working. As stated above, the research aims to develop a web site to support effective home study, enhance students' mathematical ability and reduce the burden of private lessons.

BACKGROUND/OBJECTIVES: This study aims to develop a mobile nutritional management program for integration into the already developed web-based program, Diabetes Mellitus Dietary Management Guide (DMDMG) for diabetic patients. Further, we aim to evaluate the amended DMDMG program. SUBJECTS/METHODS: The mobile application based on an Android operating system includes three parts: 1) record of diet intake, which allows users to take pictures of the meal and save to later add diet records into DMDMG; 2) an alarm system that rings at each meal time, which reminds users to input the data; 3) displays the diet record and the results of nutrient intake, which can be also viewed through the web program. All three parts are linked to the web-based program. A survey was conducted to evaluate the program in terms of nutrition knowledge, dietary attitude, eating behavior and diet intake by non-equivalent control group design among diabetic patients with 14 DMDMG users and 12 non-user controls after a one-month trial of DMDMG. RESULTS: Non-users did not use the program, but participated in the weekly off-line nutrition classes for one month. The program users showed increased healthful dietary behavior (P < 0.01) and dietary attitude scores (P < 0.05). More DMDMG users had higher nutrition knowledge scores after one-month trial than non-users. However, dietary intake significantly increased in non-user group for calcium and sodium (P < 0.05) while the user group did not show significant changes. CONCLUSIONS: The program has created positive changes in patients' dietary life. All the users were satisfied with the program, although some expressed minor difficulties with an unfamiliar mobile app.

Objectives: There is an increasing number of North Korean adolescents in South Korea. These adolescents need clinical attention as they experience a high risk of suicidal behavior because of the childhood adversity and acculturative challenges that they face before and after arriving in South Korea. This study assessed the risk of suicide attempts among North Korean adolescents compared to South Korean adolescents, and investigated the contributing factors for each group. Methods: We used data from the Korean Youth Risk Behavior Web-Based Survey (KYRBS) spanning 2011 to 2018, in which 404 adolescents had a father and/or mother who was a North Korean native. Data on 1,212 propensity-matched South Korean adolescents were extracted from the 2011 to 2018 KYRBS. Prevalence was calculated and compared by group. Separate odds ratios were calculated by group. Results: The North Korean group had a significantly higher suicide attempt rate [unadjusted odds ratio (OR)=8.27; adjusted OR=8.45]. Multivariate analysis indicated that having a low or high socioeconomic status and depressive symptoms were significantly associated with suicide attempts in North Korean adolescents, while being female, having a high socioeconomic status, alcohol use, and depressive symptoms were significantly related to suicide attempts in South Korean adolescents. Conclusion: The results found similarities and differences in the factors associated with the likelihood of suicide attempts in the two groups. From these results, different approaches are needed when planning interventions for each group.

Objectives: The aim of this study was to verify relationships between light- and heavy alcohol drinking and health-risk behaviors such as smoking, inappropriate weight control, physical inactivity, and sexual activity among adolescents. Methods: The data of 68,043 adolescents in middle- and high school collected from the Korea Youth Risk Behavior Web-based Survey in 2015 were analyzed. For statistical analysis, logistic regression model was used. Results: The rate of heavy alcohol drinking increased with increasing age up to 21.5% among boys and 13.9% among girls. Among boys, heavy alcohol drinkers were at a higher risk of smoking (adjusted odds ratios [OR]=3.3, 95% confidence interval [CI]=2.8-3.8), inappropriate weight control (OR=1.7; 95% CI=1.4-2.1), having sexual intercourse (OR=3.6; 95% CI=3.0-4.2) than light drinkers. Multiple health-risk behaviors of smoking, inappropriate weight control and sexual intercourse also increased in accordance with the severity of drinking alcohol beverage compared to non-drinker. Physical inactivity was decreased among heavy drinkers compared to light drinkers (OR=0.8; 95% CI=0.7-0.9 for inactivity of moderate exercise). Similar results were observed among girls. Conclusions: Alcohol drinking especially heavy alcohol drinking among adolescents is related to other risky behaviors including smoking, inappropriate weight control, and sexual activity. To prevent health problems in adolescents, it is necessary to adopt a combined approach regarding heavy drinking and health-risk behaviors.

Objectives: The aim of this study was to measure secular trends in health risk behaviors among middle and high school students in Korea between 2005 and 2009 by using data from the Korea Youth Risk Behavior Web-based Survey(KYRBS). Methods: The analyses were performed using data from the 2005, 2006, 2007, 2008, and 2009 KYRBS, which included a nationally representative sample of middle and high school students. A total of 34 health behavior indices were used for the assessment of secular trends in health risk behaviors. Logistic regression models were used to identify statistically significant secular trends in health risk behaviors, after adjusting for gender and grade. Linear and higher-order time variables were simultaneously entered into the statistical models. Results: There was evidence of small, but statistically significant increasing or decreasing trends in certain health risk behaviors. Secular trends in health risk behaviors varied by gender. Conclusions: This study indicates that between 2005 and 2009, changes in health risk behaviors among Korean adolescents were generally small, but represented statistically significant increases or decreases. Further research should explore why certain health risk behaviors are increasing or decreasing and what types of interventions are most effective.

Objectives: Since juveniles' unhealthy diets, and their problematic behavior resulting from drinking cause serious harm to those who are in a period of growth, we attempted to find out the relationship between juveniles' dietary habits and their drinking alcohol. Methods: The data was collected from 74,186 people in a 2012 web-based survey of Korean juveniles' health behavior, which was jointly conducted by the Ministry of Education, Science, and Technology, the Ministry of Health and Welfare, and the Korea Centers for Disease Control. This study conducted a logistic regression analysis using SPSS 18.0. Results: Juveniles who consume fast food at least once in a day have a significantly higher chance of binge drinking (OR=3.063, 95% CI=2.332~4.023), problematic drinking(OR=6.041, 95% CI=4.947~7.379) than those who don't. It also indicates that juveniles who don't eat breakfast have a significantly higher chance of binge drinking (OR=1.358, 95% CI=1.158~1.593), problematic drinking(OR=1.762 95% CI=1.548~2006) than those who eat breakfast every day. Conclusions: Irregular breakfast or a frequent intake of fast food causes problematic drinking, and binge drinking. Therefore, when planning programs for the prevention of juvenile drinking, it seems necessary to include education of healthy dietary habits.

Purpose: The purpose of this study was to compare unsafe sex experiences of multicultural and non-multicultural adolescents. Methods: The study analyzed the data of 3,029 respondents who responded that they had sex in the Korea Youth Risk Behavior Web-Based Survey of 2018. Weighted percentages and simple and multiple logistic regression were conducted using SAS 9.2. Results: As a result of univariate analysis, the odds ratio of unsafe sex was significantly higher in multicultural adolescents, but the difference between the two groups was not significant after controlling for the related variables. Among the covariates, the odds of unsafe sex were significantly higher in boys (AOR: 1.34; 95% CI: 1.08~1.66), those who did not live with their family (AOR: 1.68; 95% CI: 1.17~2.39), those with low academic achievement (AOR: 1.33; 95% CI: 1.02~1.73), binge drinkers (AOR: 1.61; 95% CI: 1.29~2.02), smokers (AOR: 1.37; 95% CI: 1.06~1.78), and those who did not receive sex education (AOR: 1.59; 95% CI: 1.20~2.11). Conclusion: There was no significant difference in unsafe sex experience between multicultural and non-multicultural adolescents. This study also shows the positive effect of school sex education on safe sex in teenagers. It is necessary to strengthen sex education for male students, students not living with their family, students with low academic achievement, binge drinkers, and smokers.
