<title>Objectives</title>
<p>This study aimed to analyze nationwide representative data from the 11<sup>th</sup> Korean Youth Health Risk Behavior Web-Based Survey to determine whether factors including socio-demographics, smoking and alcohol consumption, were factors related to high school students that had experienced sexual intercourse.</p></sec>
<sec>
<title>Methods</title>
<p>A total of 33,744 students (17,346 boys and 16,398 girls) in 1<sup>st</sup>, 2<sup>nd</sup>, and 3<sup>rd</sup> grade at high school were analyzed. SPSS complex samples methods were used for analyses. Socio-demographic and health risk behaviors (type of region of residence, family structure, and economic status, student academic achievement, gender, high school grade, pocket money, student smoking, alcohol consumption, and having engaged in sexual intercourse) were considered as independent variables.</p></sec>
<sec>
<title>Results</title>
<p>There were 3.6% of girls and 9.9% of boys in high school that were sexually active. This behavior and the average number of cigarettes smoked daily, and alcohol consumed weekly, represented a dose-response relationship, after considering confounding factors. Compared with students that did not smoke or consume alcohol, smoking 1–9 cigarettes per day and consuming 1–6 cups of alcohol and group “smoking more than 10 cigarettes per day and consuming more than 7 cups of alcohol, had a 5.94 and 22.25 higher risk of having had sexual intercourse, respectively.</p></sec>
<sec>
<title>Conclusion</title>
<p>Cigarette smoking and alcohol consumption were associated with an increased likelihood of high school students engaging in sexual intercourse.</p></sec>

<sec>
<title>Objectives</title>
<p>This research aimed to understand the popularity of topics in the field of women’s health through analysis of online news articles which were chronologically classified and examined to determine how women’s health and diseases had changed over time.</p></sec>
<sec>
<title>Methods</title>
<p>Women’s health and disease news articles were collated from a popular news website between 1993 to 2015 and preprocessed using gynecological medical terminology, Korean words and nouns (excluding general nouns not related to women’s healthcare topics). The resultant articles (N = 7,710) were analyzed using the Latent Dirichlet Allocation algorithm and major topics were extracted. Topic trends were analyzed by year and period for women’s health.</p></sec>
<sec>
<title>Results</title>
<p>It was observed that most of the women’s health articles were focused on “Healthcare”, and 9 other topics were identified that represented a relatively small proportion in 1993–2000. In 2001–2005, most of the articles were focused on “Medical Services” and “Dietary Supplements” with some specific topics that peaked people’s interest, as compared to those focused on “Healthcare” in the 1990s. It was also observed that differences in the proportion of each topic was small after 2011.</p></sec>
<sec>
<title>Conclusion</title>
<p>Changes in topics related to women’s disease were not clearly distinguished in the 1990s but this changed from 2001where articles related to “women disease” appeared as articles on the topics of various diseases.</p></sec>

All groups completed a preliminary questionnaire, before being shown a public service announcement twice, and then completed a post viewing questionnaire.</p></sec><sec><title>Results</title><p>For announcements with positive messages, the proportion of changes in beliefs and attitudes were 39.1% and 19.8%, respectively, whereas those with negative messages showed a greater proportion of changes in the beliefs (59.7%) and attitudes (40.3%). After adjusting for sex and change in belief, the message types and smoking status were identified as factors affecting the change in the participants attitudes. A negative message resulted in a greater change in attitudes (odds ratio [OR], 3.047; 95% confidence interval [CI], 1.847–5.053). Ever-smokers including current smokers showed a greater positive change in attitude than never-smokers (OR, 6.965; 95% CI, 4.107–11.812).</p></sec><sec><title>Conclusion</title><p>This study found that positive anti-smoking public service announcements were more effective on attitude change than negative messages. Additionally these announcements were more effective among viewers who were current smokers or had a prior smoking experience.</p></sec>
