The study is designed to compare differences between male and female Internet users in present Internet use conditions, Internet addition, self-respect, and deviation from a health life and analyze and understand factors causing compulsive Internet use. The research is aimed at suggesting basic information to guide a desirable direction for healthy and effective Internet use. The survey of 456 students majoring in public health at some universities in the Pusan-Kyungnam areas was made in November, 2006. The results are as follows: As for general information on those surveyed the number of the males was 50(11.0%) and that of the females was 406(89.0%), which shows an absolute higher ratio of the female respondents. On a question of Internet use frequency 62% of the male students and 44.6% of the female students answered they use the Internet everyday. Also the male respondents' Internet use time was longer. 64.0% of the male students use the Internet for games and entertainment, which were the highest ranked reason. 64.4% of the female students said they use the Internet to check e-mails. To all the questions assessing Internet addiction, the male users' answers implied higher addiction levels, but there wasn't statistically significant difference. However, the statistically outstanding distinction between the two sexes on deviation from a health life is shown in smoking, cheating in a test, obscene video/books, and conflicts with parents. The most answered deviations among the male respondents are smoking, cheating in a test, and obscene video/books, while conflicting with parents is for the female students. On self-respect the survey has found statistical differences in five questionnaire items and the female showed higher levels in all those questions. The male students answered cheating in a test(0.399), conflicts with parents(0.391), and Internet use time(0.242) have significant plus(+) influences on their compulsive internet use, while alcohol(-0.308) has a minus(-) influence. The female students answered self-respect(0.114), alcohol(0.097), obscene video/book (0.218), conflicts with parents (0.243), and Internet use time (0.284) factors have plus(+) effects.

This study was to understand associated factors with frequent exposure to Internet pornography among Korean adolescents. We used data (N = 45,783) from the 2012 Korea Youth Risk Behavior Web-based Survey to examine demographics, family environmental variables, Internet use time, mental health indicators, sexual behavior, and delinquency among Korean adolescents identified as frequent users of Internet pornography. Multiple logistic regression analysis revealed that frequent users of Internet pornography were more likely to be older males with differences in living arrangements and perceived economic status of the family. They were heavy Internet users with mental health issues, such as a higher likelihood of sadness, suicidal ideation, suicide attempts, high stress, and a lower likelihood of feeling happiness. Their higher probability of exploratory (OR =1.79-4.60), and high-risk sexual behavior (OR = 2.20-7.46), and other delinquencies (OR = 1.74-7.68) requires more attention from public health professionals.

본 논문에서는 효율적으로 주차 공간을 확보하고 주차장의 성능을 향상시키기 위한 방법 중 하나인 차량 번호판 조사를 이용하여 평균 주차 시간과 주차 회전율을 구하였다. 특이할 만한 사항은 일반적인 차량 번호판 조사는 사람이 직접 수행하게 되어있는데 본 조사에서는 사람이 직접 조사하지 않고 CCTV를 통하여 조사를 수행하였다. 따라서 적당한 조사 시간 간격(인터벌)을 두고 평균 주차 지속 시간과 주차 회전율을 구한 것이다. 이것으로 인하여 효율적으로 주차장을 사용하는지 여부와 차량의 주차 소통 여부를 쉽게 알 수 있다. 단지 실험에서 문자 인식 부분은 4-방향 프로젝션을 이용하여 추출하는데 이번 연구에선 제외하였다.

Objectives: This study aims to examine the association of depression, suicidal behaviors with smartphone use behaviors among Korean adolescents. Methods: We analyzed data from 'Youth Health and Life Skills Survey' in 2013. The survey was based on self-reported questionnaires distributed to 915 grade 7th and 8th students at four middle schools in Gangdong-gu, Seoul, Korea in 2013 to evaluate the effects of 'Youth Health and Life Skills' program. Depression and suicidal behaviors were measured in terms of the experience rate, and smartphone use behaviors were measured with average hours of smartphone use a day and overindulged behaviors in smartphone use by using 5-point Likert scales. We examined the association of depression and suicidal behaviors with smartphone use behaviors by using t-test and regression analyses. Results: 21.5% of respondents have ever felt depressed or hopeless to lose interest in school life almost everyday for 2 weeks or longer in the past year. The experience rate of suicidal ideation, suicide plan, and suicidal attempt were 21.1%, 6.1%, and 5.7%, respectively. The mean of average hours of smartphone use a day was 3.9 hours, and the mean score of overindulged behaviors in smartphone use was 2.99. The students who have experienced depression and suicidal behaviors were more likely to have more smartphone using time and higher scores of overindulged behaviors in smartphne use than those who have not. Conclusion: We concluded that for preventing addictive or problematic smartphone use behaviors among adolescents we should consider and develop more positive strategies for the moderate use of smartphone than regulatory measures, which include the implementation of skill-based health education program including life skills at schools and the development of smartphone applications useful for resolving mental stress and promoting mental health.

The purpose of this study was to identify characteristics of space usage patterns by types of elderly households(single or couple). For the study, 74 elders who were older than 65 were selected and their living behaviors at their home during a day (24 hours) were analyzed. Respondents were classified into 6 types based on a combination of their household type, income level and health status. The results showed that the elderly residents tended to live a well-regulated life, however, each type had unique time and space use pattern. For example, the more the elder residents were healthy, the more they used many rooms. Frail elderly residents spent most of the day in their bedroom. Also, if they had a spouse, each one tended to use a separate private room for his or her daily life whether they shared a bedroom or not.

본 연구는 고등학생의 스트레스가 자살생각에 미치는 영향과 인터넷 사용 및 음주의 매개 역할을 탐색하는 것을 목적으로 하였다. 이를 위해 교육부·보건복지부·질병관리본부가 공동으로 실시한 2019년 청소년건강행태조사자료를 활용하였다. 자살생각 여부에 대한 복합설계 다중로지스틱회귀분석 결과 주관적 스트레스를 '많이 느끼지 않는다'는 학생에 비해 '많이 느낀다'(OR:5.607, 95%CI:5.077-6.191)는 학생이 자살 생각을 유의하게 더 많이 하는 것으로 나타났다. 음주량의 경우 최근 30일 동안 술을 마신 적이 없는 학생에 비해 소주 2병 이상(OR:2.325, 95%CI:1.928-2.803), 소주 1병~2병 미만(OR:1.791, 95%CI:1.539-2.083), 소주 5~6잔(OR:1.795, 95%CI:1.425-2.261), 소주 3~4잔(OR:1.412, 95%CI:1.159-1.720), 소주 1~2잔(OR:1.545, 95%CI:1.325-1.802)이라고 답한 학생들이 자살 생각을 유의하게 더 많이 하였다. 마지막으로 스트레스인지와 자살 생각 여부의 관계에서 인터넷 사용시간과 음주량은 부분매개 역할을 하는 것으로 나타났다(p<.001). 그러므로 청소년의 자살문제에 인터넷 사용이 자살 생각에 매개를 하므로 이를 고려한 중재프로그램이나 메시지 개발이 필요하다.

전력은 인간생존에 있어 기본적인 요소이다. 본 논문에서는 주택용 전력에 대한 가구의 지불의사액(WTP)을 분석하고자 한다. 주택용 전력에 대한 WTP는 전력의 실제 가격과 추가적인 WTP의 합으로 정의된다. 전자는 시장에서 쉽게 관측되지만, 후자는 시장에서 관측이 불가능하므로 직접적인 가구조사를 통해 추정해야만 한다. 이를 위해 2010년 11월 전국 1,000가구를 대상으로 조사를 실시하였다. 분석 결과 주택용 전력 한 단위에 대한 추가적인 평균 WTP는 11.24원/kWh로 나타났다. 조사시점인 2010년 주택용 전력 평균가격은 98.07원/kWh이므로 주택용 전력에 대한 경제적 편익은 이 둘의 합계인 109.31원/kWh으로 추정된다. 이 값은 주택용 전력 1kWh 공급비용과 비교할 수 있을 것이다.
