This study attempts to draw a blueprint of risk analysis for Information Systems (IS). We introduce two main variables for measuring IS risk - business-impact intensity and IS-vulnerability index - through the investigation of information characteristics, business processes and human-related factors. IS-vulnerability index consists of two factors such as degree of openness and degree of preparedness to the threats. Based on these factors, we built two integrative frameworks for risk analysis and management: One is a conceptual framework to enhance the understandability of IS risk itself; the other is an integrative framework to improve the managerial insight of overall IS risk. We then conducted a field study to empirically validate the proposed framework using a structural equations modeling method. We found that IS maturity and business-impact intensity were positively correlated to degree of openness to the threats, while IS maturity was negatively correlated to degree of preparedness to the threats.

The purpose of this study is to analyze whether service quality and perceived risk have an effect on purchase intention and satisfaction of the fashion merchandise in internet shopping malls. To this end, a survey was conducted from June 20 to July 30 in 2005, among married women aged in their 20s and 30s, on their purchase experience of fashion merchandise from internet shopping malls. The survey was conducted over the internet with 306 subjects. The statistical analysis methods were frequency analysis, reliability analysis, factor analysis, and multiple regression analysis. First, the service quality factors were determined to be reliability, responsibility, ease of transaction, order convenience, and site characteristics. Perceived risk factors were determined to be merchandise risk, information exposure risk, social psychological risk, and function risk. Second, service quality factors of responsibility, ease of transaction, order convenience, site characteristics and perceived risk factor of social psychological risk had an effect on internet purchase intention of the fashion merchandise. Greater site use convenience, lower price, simpler ordering, and lower social psychological risk were all positively correlated with higher internet purchase intention of fashion merchandise. Third, nice quality factors and social psychological risk had an effect on satisfaction degree in internet shopping.

A simple and effective analysis method is presented for predicting the best infiltration area. Based on geospatial information, numerical estimation barometer for degree of infiltration risk has been derived. The dominant geospatial features influencing infiltration risk have been found to be area altitude, degree of surface gradient, relative direction of surface gradient to the surveillance line, degree of surface gradient repetition, regional forest information. Each feature has been numerically expressed corresponding to the degree of infiltration risk of that area. Four different detection probability maps of infiltration risk for the surveillance area are drawn on the actual map with respect to the numerically expressed five dominant factors of infiltration risks. By combining the four detection probability maps, the complete picture of thr best infiltration area has been drawn. By using the map and the analytic method the effectiveness of surveillance operation can be improved.

A sea dike construction has been increased in Korea because of the actively deployed reclamation project in basis of efficient application in land. The degree of completion in sea dike construction is affected by final closing construction, which has a lot of uncertainty that often results in higher accidents rate. Therefore, this research identified risk factors of final closing construction and classified them. This research examines the likelihood and its impact for each risk factor and calculates the risk degree as to the risk matrix. Based on this, the impact and the environmental conditions that affect to risk factors are investigated and further responsive methods are established for each risk factor. Ultimately, this research attempts to provide the risk retrenchment method for inspectors by proposing risk estimation model, responsive action list, and risk management process.

The purpose of this study was to examine the degree of concern about endocrine disruptors, the degree of recognition about the risk of endocrine disruptors towards humans, the degree of worry about the risk of endocrine disruptors towards ones self or family, information-obtaining behavior regarding endocrine disruptors, the degree of knowledge and the degree of behavior to decrease exposure to endocrine disruptors, and the degree of an educational need for endocrine disruptors in the dietary life of elementary school students. The data were collected from 162 students in Seoul, Incheon, Daejeon, Daegu, Busan and Gwangju. Frequencies, Cronbach's alpha, t tests, analysis of variance, Duncan's multiple range tests and chi-square tests were conducted using SPSS V.14.0 for WINDOWS. The results of this study were as follows. The degree of concern about endocrine disruptors was not high. The respondents obtained most of their information regarding endocrine disruptors from TV/radio. Respondents had difficulty in acquiring and understanding the information. Both the degree of knowledge and the degree of behavior to decrease exposure were not high. The respondents showed a high degree of educational need for endocrine disruptors, the most important was methods to prevent damage from endocrine disruptors followed by risk of endocrine disruptors.

이 연구의 목적은 위험해석모형을 적용하여 범죄두려움의 영향요인을 검증하는 데 있다. 특히, 기존의 연구들이 위험해석모형에서 제시된 미시적 개인요소를 포함하지 않고 있어 이 연구에서는 미시적 개인요소, 지역사회요소, 범죄 위험의 인지, 범죄두려움 등을 주요 변인으로 포함하였다. 이 연구에 사용된 자료는 형사정책연구원(2012)에서 실시한 '전국범죄피해조사'의 2차 자료를 활용하였으며, 해당 변인들이 범죄두려움에 미치는 개별적인 영향력을 검증하고, 위험해석모형에서 제시된 인과적 경로관계를 규명하기 위해 2단계의 다중회귀분석과 Sobel Test를 실시하였다. 분석결과, 범죄 위험의 인지가 높을수록, 여성일수록, 지역사회가 무질서하다고 인식할수록, 연령이 낮을수록, 범죄피해를 경험할수록, 학력이 높을수록, 소득수준이 높을수록 범죄두려움을 보다 많이 인식하고 있었으며, 그리고 위험해석모형에서 제시된 인과적 경로관계는 학력을 제외하고 모두 유의미하게 제시되었다.

정보통신계의 발달로 인하여 등장하는 새로운 기술들로 인하여 새로운 개인정보의 형태가 나타나고 있다. 이에 따라, 기존 개인정보들과 결합되어 사용되어지는 개인정보들이 점차 늘어나고 있다. 현행 개인정보보호법에서 정의하는 결합된 정보에 대한 개인정보 위험도를 측정하는 방법은 정성적으로 제시되고 있어, 개인정보 위험도가 평준화되기는 어렵다. 본 논문에서는 기존 연구된 개인정보 위험도 평가 방법을 기반으로 개인정보 중요도와 가중치를 측정한 다음 IPA를 통해 개인정보의 위험도를 분석하는 모델을 제시하는데 그 목적을 두고 있다. 본 연구를 통하여 사용자의 주관적인 판단을 배제할 수 있고, 결합된 개인정보 위험도 산정에 사용될 수 있다. 또한, 제시되는 정략적인 위험도는 객관적인 지표로 사용될 수 있는 기준을 제시할 수 있을 것이다.

Purpose: To establish the concept of lung cancer hazard assessment theoretical models, evaluating the degree of lung cancer risk of Beijing for regional population lung cancer hazard assessment to provide a basis for technical support. Materials and Methods: ISO standards were used to classify stratified analysis for the entire population, life cycle, processes and socioeconomic management. Associated risk factors were evaluated as lung cancer hazard risk assessment first class indicators. Study design: Using the above materials, indicators were given the weight coefficients, building lung cancer risk assessment theoretical models. Regional data for Beijing were entered into the theoretical model to calculate the parameters of each indicator and evaluate the degree of local lung cancer risk. Results: Adopting the concept of lung cancer hazard assessment and theoretical models for regional populations, we established a lung cancer hazard risk assessment system, including 2 first indicators, 8 secondary indicators and 18 third indicators. All indicators were given weight coefficients and used as information sources. Score of hazard for lung cancer was 84.4 in Beijing. Conclusions: Comprehensively and systematically building a lung cancer risk assessment theoretical model for regional populations in conceivable, evaluating the degree of lung cancer risk of Beijing, providing technical support and scientific basis for interventions for prevention.

Statistical concepts and methods are routinely utilized in a number of design and management problems in engineering hydrology. This is because most of hydrological processes have some degree of randomness and uncertainty. Thus, the concepts of risk and uncertainty are commonly utilized for designing and evaluating hydraulic structures such as spillways and dikes. Therefore, in this study, uncertainty analysis considering the variance of design floods is performed to evaluate the uncertainty of the hydrologic risk of flood related hydraulic structures using frequency analysis.
