Purpose: This study was designed to build a theoretical frame to provide practical help to prevent and manage adolescent internet game addiction by developing a prediction model through a comprehensive analysis of related factors. Methods: The participants were 1,318 students studying in elementary, middle, and high schools in Seoul and Gyeonggi Province, Korea. Collected data were analyzed using the SPSS program. Decision Tree Analysis using the Clementine program was applied to build an optimum and significant prediction model to predict internet game addiction related to various factors, especially parent related factors. Results: From the data analyses, the prediction model for factors related to internet game addiction presented with 5 pathways. Causative factors included gender, type of school, siblings, economic status, religion, time spent alone, gaming place, payment to Internet cafe$\acute{e}$, frequency, duration, parent's ability to use internet, occupation (mother), trust (father), expectations regarding adolescent's study (mother), supervising (both parents), rearing attitude (both parents). Conclusion: The results suggest preventive and managerial nursing programs for specific groups by path. Use of this predictive model can expand the role of school nurses, not only in counseling addicted adolescents but also, in developing and carrying out programs with parents and approaching adolescents individually through databases and computer programming.

Purpose: To evaluate the effects of a logotherapy education program. Methods: A nonequivalent control group, non-synchronized design was conducted with a convenience sample of 29 children with cancer. The experimental group (n=17) participated in the logotherapy education program which consisted of 5 daily sessions for one week. The control group (n=12) received the usual nursing care. The effects were measured using suffering, adolescent meaning in life (AMIL), and spiritual well-being (SWBS) scales. Results: There were significant differences in suffering (W=153.00, p<.05) and meaning in life (W=78.00, p<.05) between the experimental and control groups. However, there was no significant difference in spiritual well-being (W=136.50, p>.05). Conclusions: Logotherapy was effective in reducing suffering and improving the meaning in life. Logotherapy can be utilized for adolescents with terminal cancer to prevent existential distress and improve their quality of life.

Galactic spiral arms are abundant with interesting gaseous substructures. It has been suggested that arm substructures arise from the wiggle instability (WI) of spiral shocks. While the nature of the WI remained elusive, our recent work without considering magnetic fields shows that the WI is physically originated from the accumulation of potential vorticity (PV) generated by deformed shock fronts. To elucidate the characteristics of the WI in more realistic galactic situations, we extend our previous linear stability analysis of spiral shocks by including magnetic fields. We find that magnetic fields reduce the amount of density compression at shocks, making the shock fronts to move toward the upstream direction. Magnetic tension forces from bent field lines stabilize the WI by prevent the generation of PV. When the spiral-arm forcing is F=5% of the centrifugal force of galaxy rotation, the maximum growth rate of the WI is found to be about 1.0, 0.4, and 0.2 times the orbital angular frequency for the plasma parameter ${\beta}=100$, 10, and 5, respectively. Shocks with ${\beta}=1$ are stable to the WI for F=5%, while becoming still unstable when F=10%.

The purpose of this study was to collect basic data to develop school health policy and health promotion program. This survey measured the levels of risk behaviors in six categories in a middle school students in Kyungju(n=490). The data was collected from November to December 2000. It was done using a 1999 version of the Youth Risk Behavior Survey of CDC, which was translated and make a partial modification. The major results were as follows. Many middle school students engaged in behaviors that will increase the likelihood of death or illness. 1) A high percentage of middle school students engaged in behaviors that contribute to unintentional injuries and school-related violence (42.1 -78%) 2) Students who perceived their school life are happy experienced more depression(p=.000) and Students who perceived their school and family life are so-and-so seriously considered attempting suicide(p = .000) than other subgroup. 3) In spite of they were normal weight, 14.5% of students considered themselves overweight. 4) There was significantly difference or correlation between health risk behaviors and grade, parents educational level perception of school life and performance, perception of family life and religion. Based on this results of study, it is necessary to develop school health program and school health policy to prevent health risk behaviors and improve health promotion especially considering characteristics of middle school students.

Quality of concrete required to achieve the desired levels of strength and durability depend on the effectiveness of the curing method. During cold weather, the concrete at the time of placement should be taken to prevent damage to concrete due to freezing. Since the cement-water reaction is exothermic by nature, the temperature within mass concrete can be quite high. The temperature control for massive sections should be taken more careful than for shallow sections. However, in the constructing hydraulic structures, the curing temperature control for concrete had been very difficult to be taken in a proper way because the conditions constructing them are poor and contractors are small enterprises. For several. reasons including above, Rural Research Institute has developed a device and program for recording curing temperature history in cold weather concrete and mass. As there are two major advantages of the device, namely cheapness and availability, this program and device has been recommended to the use of curing temperature control in cold weather concrete and mass.

Purpose: This study was dont: to evaluate the factors that influence secondary traumatic stress, burnout, and physical symptoms experienced by firefighters. In addition, a hypothetical model was developed. Method: The data were collected using self-reported questionnaires from 410 field service firefighters. Data analysis was done with the SPSSWIN 10.0 program for descriptive statistics and Windows LISREL program to determine the causal relationship between the measurement variables. Results: The hypothetical model which was developed fits well with actual data(${\chi}^2$=3.16, p=0.99, GFI=1.00, AGFI=0.99, NFI=0.99, and NNFI=1.06). The variable, personality type, social support, and impact mobilization frequency had a significant effect and accounted for 7% of the secondary traumatic stress in firefighters. The variables, career, social support, and secondary traumatic stress had a significant effect and accounted for 24% of the burnout in firefighters. Social support, impact mobilization frequency, and secondary traumatic stress were important variables and accounted for 31% of the physical symptoms in firefighters. Conclusion: It is necessary for firefighters to manage themselves according to their personality types. Strategies that can increase the firefighters' social support and decrease their perceived secondary traumatic stress also need to be developed to minimize or prevent a negative effect on their health.

Purpose: This study was done to identify the predictors of smoking in middle school boys'. A comprehensive analysis of individual, family and social environment-related factors was done. Method: The participants in this descriptive survey on causal relations were 318 students enrolled in middle schools who were selected by convenience sampling. The data collected from June to July 2003 were put in to logistic regression analysis to build a prediction model. Results: 1) Individual-related factors for smoking in middle school boys' were participation in drinking and deliilquent behavior 2) Family-related factors were ill-treatment physically of the types of ill-treatment and mother being unemployed. 3) Social environment/peer-related factors were friends' attitudes towards delinquency. Conclusion and Recommendations: The experience of smoking among Korean middle school boys was associated not only with individual factors, but also with family and social environmental factors. The findings of this study suggest that broad intervention program should be provided to prevent adolescent smoking. It is also recommended that a program be developed that can help control the variables identified in this study along with a follow up study to verify the model.

A liver fluke, Opisthorchis viverrrini (OV), is the major cause of the high incidence of cholangiocarcinoma in North-eastern Thailand. The prevalence of OV infection remains high in various parts of the country, especially in wetland rural areas where a large proportion of the community work in agriculture and continue the traditional practice of eating raw or uncooked cyprinoid fish products. The national control program seems to have had little impact in many of these areas, and it has been difficult to make precise assessments of the overall effectiveness of the program. Therefore there is a need for a community-based approach to prevent infection with the parasite, ideally involving as many players as possible. Here we document an attempt to assess the best means to prevention on the basis of a community intervention in three villages in north-east Thailand, with participation of representatives of Health Promotion Hospitals of the Ministry of Public Health with dedicated staff, but also school teachers, independent government sponsored village health volunteers, and housewives responsible for cooking and diet selection. An action plan was followed, allowing detailed discussions of practical proposals, their introduction and then repeated reflection and further proposals at the individual village level.

Objectives: The purpose of the study is to investigate the awareness toward oral health and plaque removal in the elderly people in Korea. Methods: An interview method was carried out to 308 elderly people from a senior welfare facility in Mokpo, Jeonnam from May 1 to December 30, 2011 after receiving informed consents. Except 4 incomplete answers, data were analyzed using SPSS 18.0 program. The questionnaire consisted of demographical characteristics of the subjects, experience of plaque removal, recognition towards plaque removal, and correlation to systemic diseases. Results: Most of the elderly people experiences plaque removal(63.4%) and 55.9% had revisit intention. Those having plaque removal accounted for 47.8% and they had good subjective oral health recognition. Those not having plaque removal accounted for 61.8% and 61.8% having average systemic health condition and 53.3% having poor oral health recognition. The plaque removal was closely related to subjective oral health recognition. Conclusions: It is necessary to develop the preventive oral health program for the elderly people. The plaque removal in the elderly people is the most important services to prevent the systemic diseases including hypertension, arthritis, diabetes, nervous disease, and gastrointestinal diseases.
