The purpose of this study was to analyze the internet usage patterns among adolescents and to provide basic data for the development of internet addiction prevention program. The subjects of this study were 1169 students in middle and high school students in Seoul, Korea. Self-administered questionnaires were employed and data were analysed by SPSS 12.0. Major conclusions were as follows: 1. Most of the students were found to be the normal internet users. On the other hand, potential risk group was 8.2% and high risk group was 4.7%. Every students have had an experience of inter use. The 90.6% of the students' households had internet links. The percentage of students who were using internet more than 3 hours a day was 25.7%, and The most popular type of website was entertainment. 2. Male students showed greater percentages of potential risk and high risk group than female students. The students having parents in divorce, remarriage and separation were more likely to be in potential risk group than those having normal parents. The staying alone in home after school and small sleeping time were positively related to high level of internet addiction. 3. The characteristics of the students in potential risk and high risk group were longer duration of the internet use, internet use through the whole week, frequent internet use late at night, frequent use of pornographic site, main purpose of internet use for entertainment and shortage of rest during internet use. This study results had an limitation of generalizing to entire Korean adolescents because the sample of this study was middle and high school students living in Seoul. Future study was needed for the analysis of internet use behavior of the entire Korean adolescents, and for the identification of the accurate predictors for adolescents' internet addiction.

Background: Radiation is used in a variety of areas, but it also poses potential risks. Although radiation is often used with great effectiveness in many applications, people perceive potential risks associated with radiation and feel anxious about the possibility of radiation exposure. Various methods of measuring radiation doses have been developed, but there is no way for the general public to measure their doses with ease. Currently, many people use smartphones, which provide information about the location of an individual phone through network connections. If a smartphone application could be developed for measuring radiation dosage, it would be a very effective way to measure individuals' radiation doses. Thus, we conducted a survey study to assess the social acceptance of such a technology by the general public and their intent to use that technology to measure radiation doses, as well as to investigate whether such an intention is correlated with anxiety and attitudes toward the use of radiation. Materials and Methods: A nationwide online survey was conducted among 355 Koreans who were 20 years old or older. Results and Discussion: Significant differences were found between the genders in attitudes, perceptions of radiation risk, and fears of exposure to radiation. However, a significant difference according to age was observed only in the intent to use a smartphone dose measurement application. Attitudes towards the use of radiation exerted a negative effect on radiation risk perception and exposure anxiety, whereas attitudes towards the use of radiation, risk perception, and anxiety about exposure were found to have a positive impact on the intent to use a smartphone application for dose measurements. Conclusion: A survey-based study was conducted to investigate how the general public perceives radiation and to examine the acceptability of a smartphone application as a personal dose monitoring device. If such an application is developed, it could be used not only to monitor an individual's dose, but also to contribute to radiation safety information infrastructure by mapping radiation in different areas, which could be utilized as a useful basis for radiation research.

The purpose of this study was to investigate the joint-use libraries from other countries and provide some directions for the joint use library of Korea. The analyses revealed that there were two types of joint-use libraries broadly. One was school/public library, and the other was academic/public library. The advantages of joint-use libraries were the hiring of professional staff, collection increase, various library programs, and the efficient use of library space. The disadvantages of joint use libraries were the problems of the joint-use library located in school, busy space, limited library collection, and the limited function of school library. Success factors for Joint use libraries were the population of community, process of formal planning, community involvement and support, written legal agreement. This study showed two types of joint-use libraries for Korea : school/public library for rural areas and academic/public library for small cities.

Background: Traditional Korean medicine (TKM) is widely used to treat children with cerebral palsy (CP) in Korea; however, studies investigating factors that influence the use of TKM are scarce. Thus, we investigated the clinical factors that might influence the use of TKM. Methods: A population-based, cross-sectional, multicenter survey was performed from August 2014 to May 2016. The history of TKM use, type and severity of CP, current treatment characteristics, presence of accompanying disabilities or other health problems not directly related to CP, and monthly cost for the treatment of CP were surveyed. Results: In total, 182 children were recruited, and 78 children (42.9%) had used TKM. Among these 78 children, 50 (64.1% of the TKM-use group) had used both acupuncture and herbal medication, 15 (19.2%) had used acupuncture only, and 13 (16.7%) had used herbal medication only. Children with non-typical CP, accompanying disabilities and general health problems tended to use TKM. The monthly cost of treatment for CP was significantly higher in the TKM-use group than that in the no-TKM-use group, suggesting that economically disadvantaged children may have difficulty in accessing TKM. Dietary supplements, conventional pharmacological treatments, and rehabilitation therapies did not affect TKM use. Conclusion: Children with non-typical symptoms or those with poor overall health status are likely to use TKM. Additionally, TKM use leads to increased treatment costs. Studies investigating the motivation for starting or ceasing TKM therapy, socioeconomic factors and the attitude of parents towards complementary and alternative medicine should be performed.

The subjects for this study consisted of 301 Korean-American students in grades 6 to 12. Findings of this study showed that most of the risk factors in all domains demonstrated a strong relationship to the use of alcohol, tobacco, and other illicit drugs. In the community domain the most common risk factor was "laws favorable toward drug use"(60.2%); this risk factor increased the odds of substance use by approximately 3 times. The protective factor, "opportunity for positive involvement" in school domain reported by 82% of the sample decreased the probability of substance use by 3 times. The percentage of students "resilient" on all protective factors in the family domain was much lower than that of protective factors in other domains. The strongest predictors of substance use were shown in the peer-individual domain.

The purposes of this study were to explore amount of time use for house work, leisure and extracurricular lesson used by adolescents and to explain its influencing factors. Tobit model was used to analyze the factors of time use because amount of time use was a limited continuous variable. The results of this study were as follows: 1) Amount of time used for house work per day by adolescents was found to be 36min. for weekdays and 64 min. for holidays. Amount of time used for passive leisure per day by adolescents was found to be 203min. for weekdays and 375 min. for holidays. Amount of time used for active leisure per day by adolescents was found to be 74 min. for weekdays and 194 min. for holidays. Amount of time used for extracurricular lesson per day by adolescents was found to be 96min. for weekdays and 36 min. for holidays. 2) Time use for house work was found to be significantly influenced by education status, education level of mother, job status of mother for weekdays and gender, education level of mother, job status of mother, household income for holidays. Time use for passive leisure was found to be significantly influenced by education status, small children at home for weekdays and gender, education status for holidays. Time use for active leisure was found to be significantly influenced by gender, education status for holidays, while there was no influencing factors for weekdays. Finally, time use for extracurricular lesson was found to be significantly influenced by gender, education status, household income for weekdays, and age, education level of mother for holidays.

In 2003, "The National Land Use and Planning Act" (NLUP Act) was enacted unifying two old laws; "The Urban Planning Act" enacted in 1962 and "The National Land Use and Management Act" enacted in 1972. One of main reasons of unifying two acts was to extend urban planning-based development systems to rural areas for preventing uncontrolled urban sprawl in rural areas and enhancing or settlling plan-based land use system in rural areas. This paper is conducted with the following specific objectives: i) to critically review the contents of NLUP Act in terms of rational rural land use planning; ii) to evaluate plan-based land use practices in rural area by NLUP Act; iii) to appraise performance level for prevention against unplanned development activities in rural areas by NLUP Act. To accomplish these objectives, we surveyed actural state of rural land use and development system by the new act in two case study areas. Ansung city in Gyeongi province as an urban sprawl region and Hamyang county in Gyeongnam Province as a remote rural area. Study results ascertained that the new act can not effectively control rural land use and not prevent over-use of agricultural land in the positive and effective ways because of followering three points.

Purpose: This study aimed to identify students' awareness of the use of a chatbot (A-uC), a type of artificial intelligence technology, for violence prevention among elementary school students. Methods: The participants comprised 215 students in the fourth to sixth grades in Chuncheon, South Korea, and data were collected via a self-reported questionnaire. Results: The mean A-uC score was 3.43±0.83 out of 5 points. The mean scores for the 4 sub-dimensions of the A-uC tool were 3.48±0.80 for perceived value, 3.44±0.98 for perceived usefulness, 3.63±0.92 for perceived ease of use, and 3.15±1.07 for intention to use. Significant differences were observed in A-uC scores (F=59.26, p<.001) according to the need for the use of chatbots in violence prevention education. The relationships between intention to use and the other A-uC sub-dimensions showed significant correlations with perceived value (r=.85, p<.001), perceived usefulness (r=.76, p<.001), and perceived ease of use (r=.64, p<.001). Conclusion: The results of this study suggest that chatbots can be used in violence prevention education for elementary school students.

Objectives : To survey college students with an Alcohol Use Disorder, and analyze the reasons for their disorder. Methods : The cross-sectional study was conducted at 60 four-year colleges within Seoul and 9 other provinces. The schools and students selected for the study provide a nationally representative sample, and the survey was conducted between May 15th and June 14th 2003. 2,385 cases were analyzed using questionnaires, which included a series of questions about students' alcohol use and associated problems, as well as an Alcohol Use Disorder Identification Test. Results : 42.3% of students were found to have an Alcohol Use Disorder. The probability of a student having an Alcohol Use Disorder was 1.30 times higher among male compared to female students. Those students not living with their parents or relatives were 1.40 times more likely to have an Alcohol Use Disorder. Those students where the father had a drinking problem and those who admitted that their parents drank heavily while they were growing up were 1.38 and 1.54 times more likely, respectively, to have an Alcohol Use Disorder. Those students attending a general university, joining a student club, attaining less than a B average credit score and those unsatisfied with their education were 1.60, 1.36, 1.41 and 1.27 times more likely, respectively, to have an Alcohol Use Disorder. Those students who had experience of drugs, smoking, binge drinking when they were in the last year of high school and the forceful consumption of mixed alcohol were 3.67, 1.95, 2.15 and 1.76 times more likely, respectively, to have an Alcohol Use Disorder. Conclusions : College students' with an Alcohol Use Disorder is a very severe and large problem within colleges. An Alcohol Use Disorder is determined by individual and family variables, the college environmental and life variables, as well as behavior variables.
