Purpose: This study investigates university students' SNS addiction tendency, trait-anxiety and quality of sleep. This study is going to offer basic resource that required to make the way that is able to reduce the anxiety with figuring out the relation between variable. Method: 213 people participated in this study is 20 to 30 age of university students who use SNS. Collecting resource period was April 4 to May 11, 2018. Analyses consisted of descriptive statistics, ANOVA, Pearson's correlation analysis, and stepwise multiple regression analysis. Results: The findings showed SNS addiction tendency and quality of sleep(r=.45, p<.000). Major Influence factor is predicted addiction tendency of SNS using time (F=21.21, p=.000) and trait-anxiety (F=23.55, p=.000). Of the highest trait-anxiety affects quality of sleep (F=24.82 p=.000). Conclusion: These findings indicate that it is necessary to develop and implement information programs and design appropriate SNS addiction prevention programs that can induce trait-anxiety and improve quality of sleep. Thus follow-up study should have diverse participants to investigate SNS addiction tendency, trait-anxiety and quality of sleep that influenced by overusing SNS.

The purpose of this study was to investigate snacking behavior in adolescents. We selected one middle school and one high school in 11 school districts in Seoul. The subjects were 1,813 students (904 boys and 909 girls) in 21 schools (11 middle schools and 10 high schools). Subjects reported their snacking behavior: snack frequency, snack type, snack time, with whom to eat snack, place to purchase snack. The subjects were classified into four groups by gender and schooling. The mean snack frequency was 2.8. Girls ate snacks more frequently than boys (p < 0.001). More than half of subjects ate 1 to 3 snacks a day. Only 9.3% of them did not eat any snack. Tangerine was highly ranked in snack type. Each subject groups had different snack time (p < 0.01) and type of snack (p < 0.001). Most snack was consumed alone (46.6%), however they mainly ate fruits and other foods with family. 46.9% of snacks were purchased outside. A typical snack time was 'before dinner' for most snacks except fruits. Unhealthy foods like soft drinks, cookies, chips, candies, chocolates, ice creams had relatively high proportion in snack consumption with friends. In conclusion, adolescents had different snacking behaviors by their age and gender. These results indicate necessities of multi-dimensional efforts at home, school, media and government level considering adolescents' age and gender for their healthy snacking behavior.

PURPOSE. This study aimed to investigate the potential clinical application of digitized silicone rubber impressions by comparing the accuracy of zirconia 3-unit fixed partial dentures (FPDs) fabricated from 2 types of data (working model and impression) obtained from a laser scanner. MATERIALS AND METHODS. Ten working models and impressions were prepared with epoxy resin and vinyl polysiloxane, respectively. Based on the data obtained from the laser scanner (D-700; 3Shape A/S, Copenhagen, Denmark), a total of 20 zirconia frameworks were prepared using a dental CAD/CAM system (DentalDesigner; 3shape A/S, Copenhagen, Denmark / Ener-mill, Dentaim, Seoul, Korea). The silicone replicas were sectioned into four pieces to evaluate the framework fit. The replicas were imaged using a digital microscope, and the fit of the reference points (P1, P2, P3, P4, P5, P6, and P7) were measured using the program in the device. Measured discrepancies were divided into 5 categories of gaps (MG, CG, AWG, AOTG, OG). Data were analyzed with Student's t-test ($\alpha$=0.05), repeated measures ANOVA and two-way ANOVA (${\alpha}=0.05$). RESULTS. The mean gap of the zirconia framework prepared from the working models presented a narrower discrepancy than the frameworks fabricated from the impression bodies. The mean of the total gap in premolars (P=.003) and molars (P=.002) exhibited a statistical difference between two groups. CONCLUSION. The mean gap dimensions of each category showed statistically significant difference. Nonetheless, the digitized impression bodies obtained with a laser scanner were applicable to clinical settings, considering the clinically acceptable marginal fit ($120{\mu}m$).

Purpose: This study aimed to assess the prevalence of asthma, allergic rhinitis, and atopic dermatitis in elementary school students according to the body mass index. Methods: This study was conducted as cross-sectional descriptive research using a structured questionnaire. Data were collected from 6,398 students at 15 elementary schools located in Y City in Korea. The cross-sectional survey used the Korean version of International Study of Asthma and Allergies in Childhood questionnaire. Logistic regression analysis was performed to estimate the odds ratios of body mass index. Results: The symptom prevalence of asthma, allergic rhinitis, and atopic dermatitis in the last 12 months was 12.4%, 49.5%, and 24.5%, respectively. The symptom prevalence of asthma was significantly higher in the obesity group. The number of those without any asthma symptom in lifetime was significantly smaller in the overweight (OR=0.70, p=.004) and obesity (OR=0.57, p=.005) groups than in the healthy weight group. Conclusion: These results suggest that asthma, allergic rhinitis, and atopic dermatitis prevention programs for elementary school students should include weight control intervention.

2009년 4월 20일부터 5월 10일까지 전북지역 일부 중 고등학교 학생들을 대상으로 구강위생용품의 인식 및 일반적인 사용실태와 구강보건교육 경험 등을 조사한 본 연구에서의 결론은 다음과 같다. 전동칫솔과 양치용액은 인지 및 사용경험이 높게 조사되었고, 그와 반대로 치간칫솔은 인지 및 사용경험 모두 낮게 나타났다. 또한, 구강위생용품을 사용하지 않는 이유는 '잘 몰라서' 응답이 가장 높았다. 이는 구강위생용품에 대해 알고 있어야 해당 구강위생용품을 실제로 사용할 수 있다는 것을 의미한다. 대부분의 중 고등학생들의 구강위생용품에 대한 인지도와 사용률이 낮은 것으로 나타났으며, 구강보건교육 경험은 많지 않았고 구강보건교육에 대한 요구는 높은 것으로 조사되었다. 그러므로 학교 구강보건교육 시행을 위한 교육프로그램 개발과 시행이 무엇보다 중요하다고 할 수 있다. 이러한 결과는 중 고등학교 학생들의 구강위생용품의 사용 및 구강보건교육에 대한 실태를 파악하므로써 적절한 구강위생용품 사용을 권장하는 방안을 제시하고, 이를 바탕으로 학교 구강보건교육 프로그램 개발과 학교구강보건 증진을 위한 기초자료로 활용하는데 도움이 될 것으로 사료된다.

Purpose: The purpose of this study was to identify the self image according to body mass index in middle school students. Methods: The study included 260 students. Self image was measured using structured questionnaires. Statistical analysis was performed using t-test, ANOVA, Scheffe's test and multiple regression analysis. Results: The proportions of under weight, normal weight, and overweight were 36.1%, 53.9%, 10.0% respectively. Also, the mean of the self image score was 4.0. The score of self image was significantly higher in the normal weight group than the over weight group or the under weight group. This trend was also consistent in multiple regression. The score of self image was lower in high school grades, low perceived record, under-weight and over-weight. Conclusion: This study shows that many students are under weight. The score of self image was related with body image. So, level of obesity in each student should also be considered, to elevate the self image.

Background: Because premed students do not take courses related to medicine during their first 2 years, they cannot establish their identity as students at medical schools, making it difficult for them to set goals as future doctors. We conducted an early clinical and basic laboratory exposure program for premed students and studied the effects of the program and student satisfaction levels. Methods: We performed an early clinical and basic laboratory exposure program for premed students for 2 days and evaluated the effects of the program and student satisfaction with it. The program consisted of two types: type 1, where two to four students formed a group, which was assigned to a particular department to participate and make observations during ward rounds, outpatient clinics, examinations, procedures, and surgeries (in the case of basic laboratory work, the students partook in experimental observations); and type 2, where one student followed a medical school professor to observe the professor's day. After the program ended, an online survey was conducted to investigate the effects on students, their thoughts, and satisfaction levels. Results: In total, 114 students (91.2%) responded to the survey. Approximately 94% of them were satisfied with the program. They found that the program would be useful for deciding on future career paths, gaining knowledge about a department of interest, studying for a medical program after premedical studies, and befriending residents and professors in certain departments. Conclusion: Early clinical and basic laboratory exposure programs are recommended for premedical students.
