This study is aimed to examine effects of sociodemographic, social relation, and health related factors on risky drinking among early, middle, and older adulthoods. Using the sixth(2013-2016) National Health and Nutrition Examination Survey, separate logistic regression analyses were conducted for women's early adulthood (n=1,143), middle adulthood (n=1,306), and older adulthood (n=875) to test factors associated with risky drinking. For study results, as for women's early adulthood, education, marital status, employment, depressive feeling, and smoking were statistically associated with risky drinking. As for women's middle adulthood, only subjective stress level and smoking were associated with risky drinking. As for women's older adulthood, education, suicidal ideation, and subjective health condition were associated with risky drinking. These results found different factors influenced risky drinking according to life stages. Based on these results, convergent implications about reducing risky drinking according to life stages of women were discussed.

The purpose of this study is to define determinants of tourists' behavior focused on tourism omni-channel and to verify the relationship between tourism information search motivation, tourism omni-channel satisfaction, tourism experience and perceived risk. We presented the hypotheses including ease of use, trust and satisfaction and also analyzed the moderator effects of tourism experience and perceived risk(financial risk, psychological risk) variables. For an accuracy of expected results, we focused on survey with 298 respondents. Based upon prior studies, it is meaningful that this study verified 1) the positive relationship between tourism information search motivation and tourism omni-channel satisfaction and 2) the significant moderating effect of financial risk on the relationship between tourism information search motivation and tourism omni-channel satisfaction.

As the disclosure of privacy information has grown steadily, concerns about mobile services based on the personal information also increased. We aspired to reveal factors influencing the use of Location-Based services(LBS) App and analyse how the perceived risk affected between these factors and the use of LBS App. Results showed that usefulness and social influence influenced on the use of LBS App. We also found that the group who highly recognized the perceived risk was highly affected by usefulness and the group who lowly recognized the perceived risk was highly affected by social influence. Findings show that the company's strategy should be different depending on the level of consumers' perceived risk.

The purpose of this study is to analyze the scale of health risk behaviors among adolescents in Daegu area. The purpose of this study was to develop a health risk behavior measurement item for the adolescent adolescents in Korea and to analyze the validity (CVR) of the existing THI measurement items and then to quantify the health risk behavior Were compared and analyzed. As a result of the analysis, the reliability of the health risk behavior scale of adolescents developed through the factor analysis was verified to derive measurement items such as general condition, respiratory, circulatory, digestive, mental health and other items. The reliability and validity of the developed health risk behavior scale were found to be fairly good. Through these studies, it will be possible to develop a preventive program that can reduce the risk of health related adolescents' youth, and to devise a strategy that can provide basic data for policy formulation.

This study analyzed the contents of articles on GMO in Chosun Ilbo and Hankyoreh from 1994 through 2015 to check the trend of reporting on GMO as a science and technology risk issue. As a result, 'risk' and 'anxiety/concern' were continuously treated as important subjects, and there was a lack of depth and journalist's professionalism in all three periods: 'Introduction of GMO technology (1994-2000)', 'Development of GMO technology (2001-2010)' and 'Social acceptance of GMO (2011-2015).' In a comparison between the media with different ideological goals, the Chosun Ilbo had a stronger new-technological inclination to GMO than the Hankyoreh in reporting topics and tones of arguments. As a result of checking the relation of the tones in reporting with the 'risk-benefit' of GMO, reports in negative tones underlined 'risk' while those in positive tones, 'benefit.' This study could suggest improvements of subject bias and unprofessionalism in the domestic science journalism, the barometer of public awareness of disputes over science and technology risk.

This study investigates the relationship between controllability, severity, unrealistic optimism and risk perception of risk factors related to location - based SNS services for smartphone users. For this purpose, I surveyed university students who had experience using location - based SNS service. The main results are as follows. First, controllability has a statistically significant effect on unrealistic optimism. Second, Severity had a statistically significant negative impact on unrealistic optimism. Third, Controllability did not have a statistically significant effect on risk perception, Fourth, Severity did not have a statistically significant effect on perceived risk. Fifth, Unrealistic optimism had a statistically significant negative impact on perception of risk. The results of this study will contribute to the prevention of privacy incidents and the protection of smartphone users by using location - based SNS service. On the one hand, future research will need to look at the relationship between unrealistic optimism and risk prevention or coping behavior.

충돌 회피를 위한 위험도 평가에서 CPA 계산은 핵심 요소이며, AIS의 도입 이후 AIS 정보를 이용한 CPA 계산이 필수적으로 활용되고 있다. 본 논문에서는 CPA 계산에 이용되는 AIS 정보와 실제 특성을 확인하고, 선박 위치 추정에 관련된 선행 연구들을 분석하며, 이를 가상 디지털 항로 표지 서비스에 적용할 방안을 강구한다, P. Last 등의 연구는 ROT의 중요성을 강조하고 있으나, 대부분의 선박이 필요로 하는 정확한 ROT 값을 전송하지 못하고 있는 상황을 확인했고, Ling-Zhi Sang 등의 연구는 4가지 요소를 반영한 간단한 식으로 구현하여 전 해역의 데이터로 비교한 결과 2가지 요소만을 적용한 방법에 대한 정확도의 향상을 확인할 수 없었다.

IT산업의 발전에 따른 IT기기의 사용이 우리의 일상에서 없어서는 안되는 존재로 자리잡음으로써 우리의 생활의 편리함과 풍요로움을 가져다준 동시에 수많은 범죄에 악용되면서 위험에 노출되어져 있기도 하다. 이러한 범죄가 증가함에 따라 기존에 우리가 접하던 유형물 형태의 증거에서 무형의 디지털 증거가 급격히 늘어났고 형사소송법의 영역에서 매우 중요한 자리를 차지하게 되었으나 아직까지 미비한 부분들이 많고 구체적인 확립이 되지 않은 실정이기에 디지털 증거의 압수 수색에 대한 문제점을 간략히 알아보고 그에 대한 개선방안을 알아보려 한다.

In this paper, a way for maximum use of cancer risk assessment software system CARA which can assess cancer risks by using health related information only without doctor's diagnosis is proposed. A way of maximizing the usage of CARA with use of nation wide internet network is described along with the general description of CARA. If CARA is used, the damage causing by cancer can be reduced since it is possible to sort a group of people with high risks (before diagnosis at a hospital). Also, CARA is helpful for medical research by used as a tool to reveal correlations between personal information and cancers practically. Unlike other preexisting systems, CARA is a new system which can consider 30 different cancers simultaneously and it is very efficient for early detection of cancer.

Vehicle safety communications is one among the important technologies in order to protect a car accident. For this, many protocols forwarding a safe message have studied to protect a chain-reaction collision when a car accident occurs. most of these protocols assume that the time of generating a safe message is the same as an accident's. If a node predicts some traffic hazard and forwards a safe message, a driver can response some action quickly. So, In this paper, we proposes a traffic hazard prediction algorithm using the communication technique. As a result, we show that the frame reception success rate of using our algorithm to the previous protocol improved about 4~5%.
