Purpose: The purpose of this study was to examine effects of school-based alcohol prevention programs on drinking statuses of adolescents. Methods: The findings of this study was based on the data obtained from the '2015 11th Korea Youth Risk Behavior Web-based Survey. The number of study subjects were 68,043. Results: It was figured that 35.6% of the study subjects had experienced school-based alcohol prevention programs within the last 12 months. As the students got older, the chances to participate in the programs decreased (p<.01). For both middle and high school students, current drinking rates for the educated was lower than those of the uneducated students(6.6% vs 8.0%; 22.2% vs 25.9%) and it was statistically significant. A similar pattern was found for high-risk drinking rates. Those educated showed lower rates than the uneducated with statistical significance of p<.001. In addition, the educated had lower problem drinking rate than the uneducated for both middle (p<.05) and high school students (p<.001). The results of logistic regression analysis showed that school-based alcohol prevention programs had statistically significant effect on current drinking status of adolescents (p<.05). However, it had significant effect only on high-risk drinking status of high school students (p<.05) and had no effect on problem drinking. Conclusion: This study addressed effectiveness of school-based adolescent alcohol prevention programs and that it is important to develop means to implement school health education.

Objectives: This paper is aimed to study the satisfaction level and course effects of web-based PBL of the Graduate school of Public Health. Methods: Web-based PBL was implemented from March 1 to June 22 on 19 students and a survey on the satisfaction level of the lessons was taken and analyzed. For the analysis, SAS 9.1 was carried out. Results: The relation of effectiveness of the lessons according to the satisfaction level of each evaluation items, shows a significance according to satisfaction of professors, whether or not the students were satisfied in evaluating themselves (correlation, p<0.05). The satisfaction level of the evaluation on teachers and whether or not the students were satisfied in evaluating themselves shows significant influence on the effectiveness of the lessons (simple regression, p<0.05), more specifically in active class participation and understanding by the students themselves (stepwise multiple regression, p<0.05). Conclusions: In this study the attitudes of professors and students toward the lessons are major influences on the effectiveness of the lessons. Specifically, active class participation and understanding by the students themselves are the most important influences.

Objectives: This study is to develop a web-based prevention program of alcohol-related problem among university students and to examine its efficacy in changing drinking behaviors and reducing harms associated with alcohol use. Methods: An hour-length program was developed containing news paper articles, pictures, stories and questionnaires in a multimedia format such as flash, animation, and text. Survey data were analyzed to examine program efficacy from a convenient sample of 1,080 freshmen enrolled in a participating university. Results: Participation in the program has resulted in statistically significant changes in drinking behavior between pretest and follow-up, including reduction of frequency of drinking, heavy drinking, and intoxication, typical amount of drinking per occasion, and subjective norm of heavy drinking. Repeated ANOVA revealed significant increases in knowledge on alcohol related facts, including recommended drinking unit by WHO with substantial level of effect size and in making negative alcohol expectancy with very low effect size. Further studies are guaranteed with randomized controlled trial for the program effectiveness. Conclusions: A web-based prevention program of alcohol-related problems in this study was efficacious in changing drinking behavior, knowledge on alcohol-related fact, alcohol expectancy and subjective drinking norm.

Objectives: Away-from-home (AFH) eating has been associated with poor diet quality and health outcomes like obesity in developed countries. AFH eating is also emerging in low-income countries, but its influence on overall diet quality is under-researched. We examined the prevalence of AFH eating and its influence on the dietary patterns of Ugandan adults. Methods: This cross-sectional study employed a web-based survey to interview Ugandan adults aged 18 ~ 65 years. A qualitative food frequency questionnaire was used to assess the food group intake, which was then converted into daily intake frequencies. Principal component analysis was used to derive dietary patterns. The participants were then classified based on the tertiles (T) of dietary pattern scores. Results: About 75% of the 375 participants reported eating AFH. The young men, food insecure, and urban dwellers were more likely to eat AFH ≥ 5 times/week. Three dietary patterns emerged; the animal-based, beverage pattern; the high fat, sweet pattern; and the traditional, plant-based pattern. Participants who frequently ate AFH were 2.85 times and 5.64 times more likely to be in the second and third tertiles, respectively, of the animal-based, beverage pattern compared to the rare eaters (OR = 2.85, 95% CI: 1.35-6.06 for T2 vs T1; and OR = 5.64, 95% CI: 2.50-12.73 for T3 vs T1). The odds of being in the second tertile of the high fat, sweet pattern was significantly higher for frequent AFH eaters compared to the rare eaters (OR = 2.61, 95% CI:1.23-5.52). Conclusions: The prevalence of AFH eating was high. Frequent AFH eating was common among the young, male, food insecure, and urban dwellers, and was associated with unhealthy dietary patterns.

Background: Korean Working Conditions Surveys (KWCS), referencing European Working Conditions Surveys, have been conducted three times in order to survey working condition and develop work-related policies. However, we found three limitations for managing the collected KWCS data: (1) there was no computerized system for managing data; (2) statistical KWCS data were provided by limited one-way communication; and (3) the concept of a one-time provision of information was pursued. We suggest a web-based public service system that enables ordinary people to make greater use of the KWCS data, which can be managed constantly in the future. Methods: After considering data characteristics, we designed a database, which was able to have the result of all pairwise combinations with two extracted data to construct an analysis system. Using the data of the social network for each user, the tailored analysis system was developed. This system was developed with three methods: clustering and classification for building a social network, and an infographic method for improving readability through a friendly user interface. Results: We developed a database including one input entity consisting of the sociodemographic characteristics and one output entity consisting of working condition characteristics, such as working pattern and work satisfaction. A web-based public service system to provide tailored contents was completed. Conclusion: This study aimed to present a customized analysis system to use the KWCS data efficiently, provide a large amount of data in a form that can give users a better understanding, and lay the ground for helping researchers and policy makers understand the characteristics.

At a time of emphasized need for user-oriented design, methods such as Post Occupancy Evaluation are being used to measure the exact demands of the users. The conventional methods, however, have mostly been conducted based on questionnaires printed on paper, which has posed numerous problems in researches designed to measure the visual demands. Along with the continued development of the internet and computer media, there have been examples of interactive media applications as a means of improving the existing paper-based research methods. This study is a follow-up to the primary study that unveiled cautious variances of the media. 200 samples of media-based researches were extracted to be used in analysis of in-depth visual demands. 200 housewives from rural Iud development zones, who exercises the most influence in household purchases in these regions where the problem of rate of distribution Is coming under the limelight, were chosen as the subjects. The subjects were selected from land development zones of Gimhae-si and Haeundae. At first, the research was prepared as a web-based endeavor but it employed direct research of field personnel in consideration of that this research is in the beginning. This follow-up study deals mainly with the visual demands for which cautious variances were detected in the primary study and includes analysis of mainly ground Plan layout, space coloration, livingroom utilization, and vlsual composition of LDK. Media research had the advantage of zero rate of questionnaire error due to a pre-programmed search routine, and it was possible to ascertain the actual trade-off basis demands of the residents in terms of ground plan layout. In addition, whereas conventional research methods based on still images were susceptible to the preconceptions of the respondents, the interactive media allowed for easy understanding of the spatial layout and thus made it possible for all respondents to provide answers under the same conditions.

Background: This study investigated the health behaviors of North Korean, multicultural, and Korean family adolescents in Korea. Methods: The study subjects were from the Korea youth risk behavior web-based survey (2011-2013) dataset. We identified 1,954 multicultural family adolescents and twice as many Korean family adolescents. Frequency analysis was used to assess nativity and nationality of the parents, and the chi-square test was used to compare the general characteristics and health behavior of the multicultural and Korean families. Conditional multiple logistic regression was used to compare health behavior between multicultural and Korean families. Results: Of the 5,862 multicultural and Korean family adolescents, current smoking in North Korean family adolescents was higher than Korean family adolescents (adjusted odds ratio [aOR], 2.32; 95% confidence interval [CI], 1.60-3.35) after adjusting for sex, school year, perceived school record, family structure, father's education, mother's education, perceived economic status, place of residence, and survey year. A high drinking rate was significantly greater in North Korean family adolescents compared to Korean family adolescents (aOR, 2.94; 95% CI, 1.89-4.57). Odds ratios for sufficient physical activity of vigorous intensity (aOR, 1.82; 95% CI, 1.31-2.54) were significantly higher in North Korean family adolescents than in Korean family adolescents. Fast food intake (aOR, 1.96; 95% CI, 1.34-2.86) was significantly higher in North Korean family adolescents compared to Korean family adolescents. Conclusion: There were differences in health behavior between North Korean, multicultural, and Korean family adolescents. Further studies are needed to investigate the factors associated with these differences.
