  • Objectives: The objective of this study was to assess the relationship between internet addiction and health behaviors & mental health among Korean adolescents. Methods: Data from the 2010 Korean Youth Risk Behavior Web-based Survey was analyzed. Using the Korean Internet Addiction Proneness Scale for Youth-Short Form: Self Report developed by the Korean National Information Society Agency in 2008, subjects were classified into 3 groups for internet addiction including general user, potential-risk group, and high-risk group. The health behaviors and mental health were compared among the groups for internet addiction by gender. Results: There was significantly higher prevalence of internet addiction including potential-risk group and high-risk group in boys(14.1%) than in girls(8.8%). There were significant odds ratios of perceived stress, perceived depression, perceived health and happiness, and satisfaction of sleeping in both genders at potential-risk group and high-risk group compared to general user for the internet addiction. The odds ratios of smoking at high risk group, alcohol drinking at potential risk group, eating breakfast at high risk group, and moderate physical activity at both risk groups among boys were significant. Among girls at both risk group, the odds ratios of smoking, alcohol drinking, and eating breakfast were significant. Conclusions: This study reveals a significant association among internet addiction, and health behaviors, and mental health in Korean adolescents.

  • The purpose of this study was performed to investigate dietary and lifestyle habits, dietary behaviors, and food frequency according to the level of smartphone addiction among 408 university students in Kyungnam province. Statistical analyses were performed using the SPSS software package. Based on using the Smartphone Addiction Poneness Scale, 28.4% were potential-risk smartphone users and while 13.2% were high-risk smartphone users. The levels of depression (P<0.05) and stress (P<0.05) and frequency of snacks (P<0.01) were higher in high-risk and potential-risk groups than in the normal group, and meal frequency was highest in the high-risk group (P<0.01). Percentages of using a smartphone at meal time (P<0.01) and snacking while using a smartphone (P<0.01) were higher in potential-risk and high-risk groups than in the normal group. Percentages of skipping meals (P<0.001) and slow eating speed (P<0.01) due to using a smartphone were higher in high-risk and potential-risk groups than in the normal group, and percentages of taste change (P<0.05) were higher in the high-risk group than in the potential-risk and normal groups. Percentages of exercise reduction (P<0.01), body weight increase (P<0.05), sleep disturbance (P<0.001), and increase in stress (P<0.01) due to using a smartphone were higher in the high-risk group than in the normal group. Scores of dietary behaviors avoiding salty food (P<0.01) and excessive drinking (P<0.001) were higher in the high-risk group than in the normal group. Scores for frequency of oil or nuts (P<0.05) and fatty meats (P<0.01) were highest in the high-risk group. Our results suggest that effective nutrition education programs are needed to solve unhealthy dietary and lifestyle habits from high-risk smartphone users in university students.

  • Purpose: This paper examines risk factors which affect project success, and proposes a method utilizing the average potential satisfaction index(API) to evaluate how much the satisfaction level of the personnel involved in the project can change by reducing the risk. Methods: The current study derives 11 risk factors affecting project success from literature review and conducts survey of 253 subjects who have project work experience. A modified Kano's questionnaire using 5-point Likert-scale is applied to investigate the amount of satisfaction or dissatisfaction when the risk factors are reducted or not, respectively. Results: The respondents consider that the risk factors which include the three elements of project management(schedule, quality, cost) is more important than other risk factors related to the project environment, and technology and profitability. Conclusion: The average potential satisfaction index proposed in this study can measure the perception on the risk factors of the personnel involved in the project, since it has a strong correlation with the perceived importance by the respondents in this study.

  • 본 연구는 MaxEnt 모형을 활용하여 가는털비름의 잠재서식지를 예측하고, 예측된 잠재서식지와 밭면적을 활용하여 가는털비름의 잡초로서의 부정적 영향에 대한 위험도 지수를 예측하기 위하여 수행되었다. 가는털비름의 분포 예측을 위하여 MaxEnt 모형을 구축하기 위하여 남한 전국의 254지점의 분포 자료와 6개의 생물 기후 인자를 활용하였다. 밭농업에 대한 두가지 방법의 위험도 평가를 수행하였고 격자 위험도 지수(raster risk index)는 $1km^2$ 격자별로 잠재 서식지 분포 확률과 밭면적의 비율을 서로 곱하여 나타냈다. 지역 위험도 지수(regional risk index)는 잠재 서식지 분포 확률의 평균과 전체 밭 면적 중 지방자치단체의 실제 밭면적의 비율을 곱하여 산출하였다. MaxEnt모형으로 예측된 가는털비름의 잠재서식지는 실제서식지와 유사하게 나타났으며 모델의 AUC 값 또한 0.711로 좋은 설명력을 지니는 것으로 분석되었다. 잠재서식지 비율이 가장 높게 나타난 지역은 광주광역시였고 격자 위험도 지수가 가장 높게 나타난 지역은 제주도였다. 지역 위험도 지수가 가장 높게 나타난 지역은 경상북도였다. 잠재 서식지 비율과 위험도 지수의 서로 다른 순위는 외래식물의 위험성을 예측할 때 잠재 서식지 비율만을 활용하여 외래식물의 위험성을 예측하는 것보다 외래식물이 부정적 영향을 주는 대상과 결합된 위험도 지수의 필요성을 제시한다. 또한 격자 위험도 지수, 지역 위험도 지수의 서로 다른 순위는 분석의 필요성에 따라서 다양한 평가 기법이 개발될 필요성을 보여준다.

  • PURPOSES : This study is to develop ISM for potential risk factor in School Zone. METHODS : Based on the literature review, the Analytic Hierarchy Process (AHP) has been used most widely. However, it is difficult to apply in practice because the AHP results have the characteristics of the independence between each element and the interlayer can not explain the interrelationship. The Network Analysis Process (ANP) is possible to analyze the relationship between the elements and the network through the feedback. But, the reliability of the analysis fall because of complicated pair of comparison, also it is difficult to solve the super matrix. In this study, the complicated relationship between each element is inquired through the Interpretive Structural Modeling (ISM). RESULTS : The methodology of ISM is developed to remove the children's potential risk factors in school zone. CONCLUSIONS : It is possible to remove the children's potential risk factors from low level to high level step by step and improve safety. Through this, risk factors can be removed from the low-level, and upper-level will automatically improve.

  • Liquefaction of soil foundation is one of the major seismic damage types of infrastructures. In this paper, deterministic and probabilistic approaches for the evaluation of liquefaction potential are briefly summarized and the risk assessment method is newly proposed using seismic fragility and seismic hazard curves. Currently the deterministic approach is widely used to evaluate the liquefaction potential in Korea. However, the there are a certain degree of uncertainties in the soil properties such as elastic modulus and resistant capacity, therefore the probabilistic approach is more promising. Two types of probabilistic approach are introduced including (1) failure probability for a given design earthquake and (2) the seismic risk of liquefaction of soil for a given service life. The results from different methods show a similar trend, and the liquefaction potential can be more quantitatively evaluated using risk analysis method.

  • Soil contamination in the United States is managed using a risk-based decision making process. In other words, we don't ask, 'how much soil contamination can be cleaned up\ulcorner' Instead we ask, 'how much contamination can be safely left in place\ulcorner' The determination of 'safe' levels of contamination is based upon the potential for exposure and the toxicity of the contaminants of concern in soil. Potential for exposure is determined by evaluating potential exposure pathways from source to receptor given current or reasonably anticipated land use. Soil cleanup goals are then calculated for any complete exposure pathways based upon toxicity and the route of exposure. In some cases, institutional or engineering controls are also used to limit the potential for exposure. In order to prevent a continuous degradation of environmental quality, risk-based cleanup approaches must be combined with strong contamination prevention programs. In addition, alternative risk management approaches should be incorporated into an overall risk reduction strategy.erall risk reduction strategy.

  • 비흡연자가 환경중의 담배연기를 흡입하게 되면 폐암유발 위험성을 증대시킨다는 주장이 미국, 유럽, 일본 그리고 몇몇 아시아 국가에서 제기되어 왔다. 본 논문에서는 한국에서 이러한 잠재위험성의 사실여부를 판단하는데 이용될 수 있는 현재까지의 과학적 근거를 제시하고 그에 대하여 토의하고자 한다. 잠재위험성의 성격, 환경중의 담배연기량에 대한 반응과 관련된 자료, 그리고 환경중 담배연기에 대한 실제적인 노출형태를 구분할 수 있는 자료 등이 토의된다. 잠재위험성에 대한 최종적인 판단은 한국의 공중보건정책의 기초로서 잠재위험성의 평가임무와 관련된 자격을 갖춘 사람들에게 맏겨질 것이다.
