Cases of botched information systems implementation have been surfaced due to poor IS project management and control. One major source of such failures is the perceptual difference between the participants of IS projects who should define potential risk factors well before considered IS projects are launched. Based on risk factors cited from prior works, this paper empirically examines the risk factors associated with IS service project management to analyze perceptual differences between the IS service providers and customers in Korea. Data analyses found significant differences in the area of scheduling/resource, technological newness, communications, and sponsorship/ownership while statistically significant differences were observed in eleven individual factors out of forty six risk factors. Risk factors are also ordered in terms of perceived importance to highlight the critical differences.

Analysis of construction tender documents in overseas projects is a very important issue from a risk management point of view. Unfortunately, majority of construction firms are biased by winning contracts without in-depth analysis of tender documents. As a result, many contractors have incurred loss in overseas projects. Although a lot of risk analysis techniques have been introduced, most of them focus project's external unexpected risks such as country conditions and owner's financial standing. However, because those external risks are difficult to control and take preemptive action, we need to concentrate on project inherent risks. Based on this premise, this paper proposes a project-oriented risk mining approach which could detect and extract project risk factors automatically before they are materialized and assess them. This study presents a methodology regarding how to extract potential risks which exist in owner's project requirements and project tender documents using state of the art data analysis method such as text mining, data mining, and information visualization. The project-oriented risk mining approach is expected to effectively reflect project characteristics to the project risk management and could provide construction firms with valuable business intelligence.

The purpose of this study is to examine children's/adolescents' motives for playing internet games and adaptation to school in accordance with their frequency levels of playing internet games. Participants were 236 children from grades 4, 5, and 6 in two elementary schools and 237 adolescents from grades 1, 2, and 3 in one middle school. They were measured on frequency levels of playing internet games, motives for playing internet games, and adaptation to school. Collected data were analyzed by SPSS WIN 12.0 for reliability, frequency, Chi-square test, t-test, Pearson's correlation, and one way ANOVA. Major findings of the research are as follows: First, children's/adolescents' frequency levels of playing internet games differed by their gender. The male ratio was much higher than the female ratio in the potential risk group and the high risk poop. In contrast, no grade differences on the frequency levels of playing internet games were found. Second, children's/adolescents' motives for playing internet games differed by their gender. Especially, among the motives the greatest difference between male and female was marked for 'Social Relationship'. Third, children's/adolescents' motives for playing internet games differed by their frequency levels of playing internet games. For 'Conformity,' the low risk group differed from the high risk group. For 'Spending Time', 'Benefit', 'Competition', and 'Social Relationship', the low risk group differed from the potential risk group and also from the high risk poop. Fourth, children's/adolescents' adaptation to school differed by their frequency levels of playing internet games. The high risk group exhibited a low level of adaptation in 'Academic Activities', 'a subcategory of adaptation to school.

The purpose of this study was to inquire into how children's internet addiction is affected by home environments, computing environments, parental marital conflicts, parenting attitudes and parental monitoring and control as perceived by children. The study was conducted on 579 sixth graders at elementary schools located in Daejeon City. The data was analyzed by frequency, percentage, $X^2$, one way ANOVA, and scheffe analysis using the SPSS 18.0 version program. The results were as follows: first, out of 579 students, 5.0% were classified as at high-risk for addiction; 22.8% as at potential-risk; 72.2% as normal. Second, in the high-risk group, boys accounted for a higher percentage compared to girl students. Mothers' academic backgrounds and fathers' occupations affected the children's internet addiction. Third, the high-risk group tended to use the internet in internet cafes, to use it before going to elementary school, to use it for at least 4 hours once, and to use it to play games. Fourth, the high-risk group perceived parents marital conflicts as more frequent and more severer, as compared to other groups. Fifth, while the high-risk group perceived parenting attitudes as negative, the normal group perceived them as positive. Sixth, the potential-risk group and the normal group perceived parental monitoring and control as more frequent, as compared to the high-risk group.

This study begins with a review of commonly discussed dimensions of public risk perception that may influence public opinion toward risks. Factors that have been revealed by the literature to have substantial impact on risk perception, such as demographic background, trust, and media environment, are also discussed. Meanwhile, we evaluate two well-known research models in the realm of risk analysis: 1) the psychometric paradigm, and 2) the social amplification of risk framework (SARF). Based on a literature review, this study suggests that, besides the psychological and social approach, models of risk perception and risk communication research should shift to a more comprehensive one by considering the interrelations between laypeople and the environment. This study proposes a research model from the perspective of social cognitive theory (SCT) as a potential framework for future studies: 1) in the societal environment, individuals' risk perception and information seeking behavior, which is determined by risk perception will be influenced by trust in regulators and interpersonal trust; 2) in the media environment, individuals' risk perception and information seeking behavior will be influenced by individuals' perceived information characteristics. Knowledge about risk accumulated through information seeking will change risk perception in a longitudinal process.

In this paper, we describe a rule-based risk classification algorithm to perform Risk-based Inspection (RBI) on imported goods at customs. The RBI system is a method to automatically select which cargos have to be inspected and manage potential risks in boarder. In this study, we designed a rule-based risk classification algorithm for RBI solutions and implemented them using the Svelte web application framework. The risk classification algorithm proposed in this paper uses different indicative risk factors such as HS code, country of origin, importer's reliability, trade relationships, and logistics routes to classify cargos into Green, Yellow, and Red channels. To achieve this, we assigned risk categories to each risk factor and randomly generated risk scores within a specific range for each risk category. This system is expected to contribute to the increased efficiency of customs operations and protect public safety by minimizing the risk of imported hazardous materials.

As an increasing demand for rapid railway transportation, the construction of sidetrack is inevitable to operate local and express trains simultaneously. However, the current technologies for the sidetrack construction method require a long construction period by interrupting the operation of the existing subway line, as well as cause a huge economic loss. Thus, it is necessary to study the sidetrack construction method under the special situation that the subway is in operation and to analyze the risk of the existing tunnel enlargement process for the sidetrack construction. Therefore, in this paper, the Government Complex Gwacheon station on Subway Line 4 was considered as a target station for the virtual sidetrack construction and the optimal sidetrack construction plan was derived. Subsequently, the application of risk management process was carried out in the order of identifying risk, risk response planning, performing a risk analysis, risk monitoring and control for potential risk events during the construction of sidetrack under the subway operation. A total of eight potential risk events and risk mitigation methods were selected, and a risk assessment matrix was established using the five-step risk probability and impact level criteria to perform the risk assessment including residual risks. Based on the results of the risk assessment, the risk grade and the reduction effect of each risk mitigation method were confirmed.

In general, risk management consists of a series of processes or steps including risk identification, risk analysis, risk evaluation, risk mitigation measures, and risk re-evaluation. In this paper, potential risk factors that occur in shield TBM tunnels were investigated based on many previous case studies and questionaries to tunnel experts. The risk factors were classified as geological, design or construction management features. Fault Tree was set up by dividing all feasible risks into four groups that associated with: cutter; machine confinement; mucking (driving) and segments. From the Fault Tree Analysis (FTA), 12 risk items were identified and the probability of failure of each chosen risk item was obtained.

The collision problem is one of the design factors that must be carefully considered for the risk of collision occurring during the operation of ships and offshore structures. This paper presents the main results of the ship collision study, and its main goal is to analyze potential crash scenarios that may occur in the FLNG (Floating Liquefied Natural Gas) considering the likelihood and outcome. Consideration being given to vessels visiting the FLNG and surrounding vessels navigating around, such as functionally supported vessels and offloading carriers. The scope includes vessels visiting the FLNG facility such as in-field support vessels and off-loading carriers, as well as third party passing vessels. In this study, based on QRA (quantitative risk assessment), basic research methods and information on collision are provided. Based on the assumptions and methodologies documented in this study, it has been possible to clarify the frequency of collision and the damage category according to the type of visiting ship. Based on these results, the risk assessment results related to the collision have been derived.
