Objectives: This study is to offer basic data to understand the relationships between mental health, level of depression, and internet addiction of high school students in farming communities for developing a mental health management program for adolescents. Methods: The survey was carried out on a convenience sample of 299 high school students in farming communities during May of 2008. Data analysis procedure included $X^2$-test, t-test, Pearson correlation among Adolescent Mental Health & Problem-behavior Screening Questionnaire (AMPQ), Children's Depression Inventory (CDI), and Scales of Internet addiction (K-scales). Results: First, the level of mental health according to the AMPQ for subjects from this study showed problematic behavior was lower when compared to other researches. There were statistically significant differences according to the school type for externalization problems and overall problematic behavior. Based on gender, it was even more problematic for male students in regards to externalization problems. Secondly, the level of depression was relatively low : 5.1% for potential risk and 0.3% for high risk. Thirdly, a total of 96.9% were considered normal for Internet addition levels. 1.7% for potential risk, 1.4% for high risk; however, there was no statistically significant difference between each variable. Fourthly, there was a strong relationship between subjects AMPQ, level of depression and Internet addiction. As depression worsens, Internet addiction also becomes stronger. Conclusion: There is a need for awareness of the mental health of adolescents and precautionary measures, the development of a program for early treatment, adequate management, and decisions on the direction of treatment.

This study aimed to identify the effects of using storytelling techniques in sex education, in which students are encouraged to talk about their experiences with sex and love and helps them form their own sex values and decision-making skills related to sex. A five-period teaching-learning plan covering issues including safe, considerate and responsible sex was developed using the storytelling technique for 134 first-year students in 4 classes. 134 questionnaires were administrated through pre-and post-test and 38 worksheets applying a variety of storytelling activities were analyzed using content analysis. Students were found to have gained a more positive outlook on relationships and a considerate attitude towards others in sex. There was also a significant increase in items considering safe sex, including perceptions on contraception methods and selection of safe contraception methods. The students' sense of sexual responsibility was also enhanced. Results of content analysis found students to have shifted to sex focusing on love and responsibility, and to have grown a stronger sense of responsibility in their relationships. Furthermore, the respondents expressed interest in selecting proper contraception methods and held strongly negative perceptions about abortion.

우리나라는 홍수조절이나 통제를 목적으로 10개의 다목적댐을 통한 홍수방재시스템을 운영하고 있다. 다목적댐 또한 방류능력과 저류능력에 한계가 있기 때문에 안정적인 홍수조절을 위해서는 유입량과 유출량을 미리 예측할 수 있어야 한다. 하지만, 강수량은 그 변동이 심하여 정확한 예측이 어렵기 때문에 합리적인 하천 구조물의 설계와 홍수예측기술의 발전을 위해서는 강우-유출 해석뿐만 아니라 과거의 수문자료를 사용한 통계적인 분석이 요구된다. 최근 기후변화로 인해 과거에 겪지 않았던 이상 기후현상이 빈번하게 나타나고 있다. 기상청발표에 따르면 최근 10년간(1996~2005) 15개 지점의 평균 연강수량은 1,458.7 m로 약 10 �時貂� 하였고, 특히 여름철은 18 %로 증가폭이 가장 크며 호우일수는 30년 평균이 2일인데 비하여 2.8일로 0.8일 증가하였다. 이러한 강수량 및 호우일수 증가는 여름철 심각한 수해를 초래할 수 있다. 본 연구는 기후변화로 인한 수해를 대비하여 홍수기중 저수지 제한수위운영의 안정성을 검토하였다. 연구 대상 지역은 광교저수지로 수원천 상류부인 경기도 수원시 장안구 연무동에 위치한다. 유역면적은 10.98 km, 유효저수량은 250.0 만$m3$이며, 현재 예비취수원으로 사용되고 있다. 기후변화에 따른 하류지역의 예상치 못한 홍수피해를 사전에 예방하기 위해 광교저수지 유역의 설계 강수량과 설계 홍수량을 산정하였다. 제한수위의 시나리오는 현재 시행중인 제한수위와 만수위를 포함하여 5개로 설정하였다. 설계 홍수량이 광교저수지로 유입될 때 시나리오에 따른 월류량은 웨어공식을 이용하여 산정하였으며 결론은 다음과 같다. 1. 39년간의 최다 일 강수량 자료를 사용하여 100년 빈도의 설계 강수량을 Gumbel 분포법으로 산정한 결과 344.4 mm임을 알 수 있었다. 2. 광교저수지 유역의 설계 홍수량을 SCS 방법을 이용하여 산정한 결과 $216.2\;m^3/s$/s로 나타났으며, 총 유입량은 $301.0\;m^3$/day로 파악되었다. 3. 광교저수지로 설계홍수량이 유입될 때 제한수위 시나리오에 따른 최대 방류량은 EL. 87 m의 경우 $23.1\;m^3/s$, EL. 89 m의 경우$27.5\;m^3/s$ EL. 91.36 m의 경우 $79.6\;m^3/s$, EL. 93 m의 경우 $121.1\;m^3/s$ EL. 95.2 m의 경우 $137.`\;m^3/s$이다. 광교저수지 하류부분의 하천정비기본계획상의 설계 홍수량은 $114\;m^3/s$로 홍수기중 저수지의 제한수위는 EL. 91.36 m이하로 설정하는 것이 바람직한 것으로 판단된다.

As many stakeholders are taking part in the Housing Redevelopment Project, their opinion mediation is considering very important issues. Thus disputes on projects are inevitable due to complexity of interest. To effectively progress the project, this paper analyze the risk factors by phase in implementation phase that the association participates in person. We identify 50 of risk factors in implementation phase by reviewing and analyzing related studies and actual cases of disputes, then we present 26 of risk factors through experts interview. Also, we calculate weights of risk factors by using AHP for quantitatively analyzing them and present final weights and priorities of risk factors by summing weights of risk factors by phase. In results, it is found that 'the inappropriateness of the Management Disposal Plan' in management disposal plan phase and 'the inappropriateness of the Project Implementation Plan' are the most significant risk factors. To maximize the utilization of risk factors analyzed, we present the checklists that can be aware of these risks in advance and prevent these risks. Based on these findings, if risk factors in implementation phase are managed actively, the housing redevelopment project will be performed more effectively.

Although the environmental conflicts regarding noise and vibration are continually increasing during construction, noise and vibration occurring in construction are only managed in construction phase. Noise and Vibration occurring in construction are considered to be insufficient, so we find that noise and vibration management in design phase has to be operated for reducing. The objective of this paper is to present noise and vibration management lists to consider in design phase for enhancing efficiency in noise and vibration management and to develop the appraisal sheets for designers to evaluate and the manuals to easily use management lists. To achieve this, we identify the noise and vibration management lists to consider in design phase through analyzing the previous literatures and confirm the 9 lists through conducting a research with experts in environmental area for verifying the propriety of lists. Also, this study applies to AHP technique to identify the priority and the weight evaluation among the lists. Through this study, we identify the most efficient lists, including from the low noise and low vibration methods, the noise and vibration reduction by blasting works, the installment and the arrangement of noise and vibration control equipments, for noise and vibration management in design phase. The achievement of this study will help to prevent the environmental disputes and conflicts in advance and will consider utilizing for the successful construction project.

In this study, the management polices of micropollutants (MPs) were reviewed and the future management strategy was discussed considering climate change and etc. In Korea, the investigation of drinking water has been actively carried out for the priority contaminants as well as MPs. Recently river and lake waters have been also examined for MPs. However, the coverage and depth of the investigation is limited. Moreover, climate change is likely to increase air & water temperature and it will affect the hydrological cycle. Such changes may increase the residual concentrations of MPs in water system. As water reuse increases, the residual MPs of the recycled water may create public concerns. Thus, in a viewpoint of the precautionary principle, more stringent management of MPs is recommended for the drinking water and the body-contact water use. For the surface water, more studies are necessary to understand the ecological risk by MPs.

The purpose of this study is to analyze the risk of the forest fire, considering the topography and the forest, for establishing disaster prevention measures of cultural heritage, Uireung, over in Cheonjang-mountain. To do that, we estimate the occurrence and spread of the forest fire over in Cheonjang-mountain through a forest fire probability model(logistic regression), using the space characteristic data($100m{\times}100m$). The factor, occurrence of the forest fire, are diameter class, southeast, southwest, south, coniferous, deciduous, and mixed forest. We assume the probability of the fire forest in each point as follow : [1+exp{-(-4.8081-(0.02453*diameter class)+(0.6608*southeast)+(0.507*southwest)+(0.7943*south)+(0.29498*coniferous forest)+(0.28897*deciduous forest)+(0.17788*mixed forest))}]$^{-1}$. To divide dangerous zone of the big forest fire, we make the basic materials for disaster prevention measures, through the map of coniferous forests, deciduous forests, and mixed forest. The damage of cultural heritage caused by a forest fire will be reduced through the effective preventive measures, by forecast a forest fire to using this study.

This study developed an instrument to assess the effects of the bullying of nurses in the workplace and evaluated the developed instrument. A literature review and a field study were conducted to identify the concepts related to the bullying of nurses in the workplace. These attributes served as building blocks to produce a 28-item WPBN-CI. The content validity was used to determine the content and face validities, and the number of instrument items was reduced to 14. The final WPBN-CI instrument was evaluated using the SPSS 18.0 program with the data collected from October 21-28, 2013 from 458 nurses from general hospitals in the metropolitan area. The WPBN-CI consisted of 13 items covering three distinct factors (physical and psychological withdrawal, poor quality of patient care, and increasing distrust), with a total variance of 62.9%. The convergent and determinant validities for the WPBN-CI were 100% and 89.7%, respectively. The known-groups validity was proven through the mean difference in the level of depression. The satisfied criterion validity for the WPBN-CI was more than 0.70. The reliability of the WPBN-CI was demonstrated by its Cronbach's ${\alpha}$ of 0.90. The WPBN-CI will identify in advance the results due to the bullying of nurses in the workplace and will help to find solutions to the problem and ensure program effectiveness.
