  • The purpose of this study is to test the typicality effects to aesthetic response according to product orientation (design-oriented vs function- oriented) and perceived purchase risk. This study overcame the limitations of existing researches which haven't had the consensus about the relationship between typicality and preference and consequently suggested the typicality effect to aesthetic response by analyzing this relationship with product orientation and perceived purchase risk. The results of this study showed the inverted U-shaped relationship in design-oriented products and no relationship in function-oriented products between typicality and preference.

  • Prognosis is an anticipation of the probable response to periodontal therapy and a long-term prospect for maintaining a functional dentition. Hopeless cases or cases of simple gingivitis without systemic diseases generally have little problem to establish definite prognoses. However, it might become somewhat challenging to determine their prognoses in borderline cases. A risk factor for periodontal disease may be environmental, behavioral, or biologic factors that can be defined as an occurrence has been associated with destructive periodontitis. Some risk factors are modifiable, while others cannot be modified. Modifiable risk factors are environmental or behavioral in nature in contrast non-modifiable risk factors are usually intrinsic to the individual and therefore not easily changed. In this review, we will assess the various modifiable or non-modifiable risk factors for susceptibility 10 periodontal diseases.

  • This study has been performed to investigate the risk perceptions of employees in nuclear power plants. A representative sample of 473 employees was surveyed(about 79% response rate). The questionnaire included scales on both risk perceptions of critical five hazards that could be occurring in the nuclear power plants and two psychometric attitudes. Higher risk perceptions between managers and non-managers to five hazards used in this study were entirely obtained from the managers. It was also found that the perceived higher hazards were in the following order: radiation exposure, radioactive release, explosion, fire and radioactive waste. For the controllability, higher risk perceptions to the all factors were obtained from the managers, and higher ones were non-managers in the dread.

  • Risk Assessment to list possible safety disasters and their probability and severity is the starting point for effective safety management on construction project site. However, the safety managers in owners, construction supervisors, contractors, and sub-contractors still have difficulties in judging the priorities of safety activities and preparing responses to each potential safety disasters. Therefore, this study aimed to suggest a systematic method in assessing safety risk prior to commencement with the agreement of stakeholders. FMECA(failure mode effects and criticality analysis) was selected as a main assessment tool and it was modified according to the characteristics of construction projects and trades. Each risk is, firstly, evaluated with occurrence probability, possible loss and impacts to projects, and detections, and then risk priority number(RPN) is calculated. Subsequently, the managers of each stakeholder discuss the types, timing, and responsibilities of responses as a group decision-making process.

  • Most construction companies recognize the necessity of risk management. The practical application, however, is not easy because of the absence of systematic procedure for risk management and the difficulty in objectification of subjective risk factors. This study suggests a systematic procedure and a web-based analysis system. In the first place for those researches, this study analyzes the present condition of risk management in the railway facility construction industry. Finally, this study defines risk management procedures as preparation, identification, analysis, response and risk analysis method to manage potential risks in the railway construction project.

  • This study focuses on the health risk assessment of airborne volatile organic compounds (VOCs) in a petrochemical complex, with several emphases on a risk assessment method. The first emphasis is on the importance of hazard identification to determine the likely carcinogenic potential of a VOC. Without considering this type of information, a direct comparison of the carcinogenic risks of two pollutants is meaningless. Therefore, wer suggest that this type of information be prepared and be listed with the estimate of cancer risk in parallel. The second emphasis is on the selection of a better dose-response model to estimate unit risk or cancer potency factor of a carcinogenic VOC. Finally, probilistic risk assessment method is discussed and recommended to use within a comparison of conventional point-estimate method. A health risk assessment has also been carried out. For non-carcinogenic risk, even the highest hazard index for carbon tetrachloride is estimated to be less than 1 with the other VOCs less than 0.03. However, the lifetime cancer risk from the inhalation of airborne VOCs is estimated to be about $2.6 \times 10^{-4}$ which is higher than the risk standard of $10^{-6}$ or even $10^{-5}$. Therefore, the investigation into domestic petrochemical complexes should be strengthened to obtain more fine long-term airborne VOC data.

  • The science and technology of seismic hazard mitigation are increasingly being shared among scientists and policy makers around the world. Administrative expertise is also being shared. While there is still tremendous unevenness in technical and administrative capacities and resources, a global community of emergency managers is developing and there is a globalization of expertise. Hazards are better understood, tools for risk assessment are improving, techniques for hazard mitigation are being perfected, and communities and states are implementing more comprehensive disaster preparedness, response, and recovery programs. Priorities are also emerging and hazard mitigation has emerged as the priority of choice in North America and Europe. An increasingly important component of hazard mitigation is resilience, in terms of increased capacities for disaster mitigation and recovery at the community and even individual levels. Each year, more is known about the locations and natures of seismic hazards, although there are still unknown and poorly understood fault lines and limited understanding of related disasters such as tsunamis and landslides. More is known about the impact of earthquakes on the built environment, although nature still provides surprises to confound man's best extorts to reduce risk. More is known about human nature and how people respond to uncertain risk and when confronted by certain catastrophe. However, despite the increased understanding of seismic phenomena and how to protect people and property, there is much that needs to be done to reduce the risk, particularly in major metropolitan areas.

  • In Korea, talc that has been widely used for a lot of consumer products as well as industrial usage until recently was found to be contaminated with asbestos. It becomes a major social issue. Critical health risk about both talc and talc contaminated with asbestos was summarized through literature review. It has been confirmed that talc can pose ovarian cancer when talc powder is used in the genital area. International Agency for Research on Cancer (IARC) already concluded that the perineal use of cosmetic talc can cause possibly carcinogenic to humane(Group 2B), although there was study reporting the lack of a consistent an established correlation between perineal dusting frequency and ovarian tissue talc concentrations and the lack of a consistent dose-response relationship with ovarian cancer risk. The association between talc exposure and ovarian cancer is as strong as in recent studies. The epidemiological studies to date provided inadequate evidence for the carcinogenicity of either inhaled or ingested talc that does not contain asbestos or asbestosiform fibers. Future studies should focus on seeking evidence in talc-exposed populations, collecting reliable information on age at initial used of body powder, exposure assessments related to talc use and dose response relationship in order to identify possible risk of talc ingested or inhaled.

  • The 4th Industrial Revolution technology has emerged as a solution to build a hyper-connected, super-intelligent network-oriented operational environment, overcoming the obstacles of reducing troops and defense budgets facing the current military. However, the overall risk management, including the increase in complexity of the latest inform ation technology and the verification of the impact with the existing information system, is insufficient, leading to serious threats to system integrity and availability, or negatively affecting interoperability between systems. It can be inhibited. In this paper, we suggest cyber threat response strategies for our military to prepare for cyber threats by examining information security risk management in the United States in order to protect military information assets from cyber threats that may arise due to the advancement of information technology.

  • This study is performed to estimate the prevalence of metabolic syndrome among male workers and to identify the relationships with many related factors including anthropometry, hematological index, serum lipid level, dietary-related behaviors and health-related behaviors. According to the age groups, the 20s are significantly higher in normal and risk groups than in the metabolic syndrome (MS) group, the 30s are significantly higher in MS group than the other groups. The levels of AST and ${\gamma}$-GTP both show significant differences in the order of MS group ($30.3{\pm}8.8U/l$, $91.1{\pm}40.2U/l$) > risk group ($25.7{\pm}8.1U/l$, $41.8{\pm}20.2U/l$) > normal group ($22.8{\pm}6.0U/l$, $26.6{\pm}10.7U/l$). For the frequency of breakfast consumption, the response of 'Every day' is significantly higher in MS group than normal and risk groups, but the response of 'Not at all' is significantly higher in normal group than MS and risk groups. The drinking amount is positively correlated with ${\gamma}$-GTP in normal group, and it is negatively correlated with the hematocrit level, but it is positively correlated with the systolic blood pressure in MS group. AST is positively correlated with glucose concentrations of the MS group. The ALT is positively correlated with waist circumferences and systolic blood pressure in the risk group. The results of this study show that breakfast frequency, education level, drinking amount, drinking frequency, exercise frequency, AST, ALT and ${\gamma}$-GTP levels are all important risk factors of MS. Therefore, it is very important to maintain a healthy life style for the prevention of MS incidence.
