  • The study investigated the relationship between vitamin D status and lifestyle risk factors in office workers. A total of 515 office workers(336 men and 179 women) aged 30 years or older were voluntarily recruited from S-city. Along with serum vitamin D levels, lifestyle risk factors including obesity index, physical fitness, metabolic risk factors, lipids profile and sedentary behavior were measured using standardized protocols. Subjects were classified as deficiency (<20ng/mL), insufficiency (20-29ng/mL), and sufficiency (≥30ng/mL) based on serum vitamin D levels. Linear contrast analysis using one-way ANOVA showed significant linear decreases in mean body fat (p=.030) and sedentary behavior (p<.001) and significant linear increases in skeletal muscle (p=.037), cardiorespiratory fitness (p<.001) and HDL-C (p=.013) across incremental serum vitamin D levels. Compared with the low cardiorespiratory fitness group, the high cardiorespiratory fitness group had a significantly higher odds ratio (men OR=2.144, p=.042, women OR=1.971, p=.045) for having vitamin D insufficiency or deficiency even adjustment after age. Compared to the shortest sitting time group, the longest sitting time group had a significantly higher odds-ratio in a group of female office workers (OR=1.262, p=.043) for having vitamin D insufficiency or deficiency even adjustment after age. The current findings of the study showed that poor physical fitness and sedentary behavior were the risk factors of low serum vitamin D levels, implying the urgent need for a healthy lifestyle modification along with vitamin D supplementation.

  • Construction uncertainties are frequently exposed to the claims. In most cases, an interpretation of the claims is based on the construction contract. Therefore, the key points of contract negotiation are how to fairly distribute the contract risks to the client and contractor. For these, a FIDIC that is considered as an international standard contract form would be a good reference to decide reasonable contract risk distribution. In order to find out any unreasonable and unfair contract clauses at the general conditions of contract applying generally to public construction project in Korea, this study surveys, analyses and evaluates the general conditions of contract based on a FIDIC, and then proposes a risk mitigation methodology to response those clauses' risk factors reasonably.

  • Risk analysis is utilized in devising measures to manage information security risk to an acceptable level. In this risk management decision-making, the visualization of risk is important. However, the pre-existing risk visualization method is limited in visualizing risk factors three-dimensionally. In this paper, we propose an improved risk visualization method which can facilitate the identification of risk from the perspective of confidentiality, integrity, and availability respectively or synthetically. The proposed method is applied to an enterprise's risk analysis in order to verify how effective it is. We argue that through the proposed method risk levels can be expressed three-dimensionally, which can be used effectively for information security decision-making process for internal controls.

  • This study aims to empirically verify that the effect of investor protection on risk taking may differ according to growth opportunities. Furthermore, this paper intends to verify the hypothesis that the impact of risk taking upon corporate value will also be influenced by growth opportunities. The results of the analysis show that firms with high growth opportunities demonstrate greater risk taking as investor protection gets stronger while the degree of investor protection has little or no impact on their risk taking in case of firms suffering a lack of growth opportunities. In addition, risk taking has a statistically significant positive impact on improving corporate value for firms with sufficient growth opportunities, in contrast the impact is little or none when firms lack growth opportunities.

  • In Korea, hydrogen stations are being promoted and commercialized. However, the risk assessment for the hydrogen station is not clear. In particular, it is not clear how to calculate the risk and acceptable criteria for a hydrogen station. Therefore, in this study, three hydrogen stations being installed were selected and general risks were calculated and the social risk of each hydrogen station was calculated. In general, the method of risk assessment is individual/social risk. This is an individual's death rate considering the frequency of accidents, And the likelihood of death according to the number of nearby residents. These can be used to calculate the level of risk for a hydrogen station. However, this method of calculate risks is the criteria for judging whether it is acceptable are unclear. For this reason, this study investigated the allowable standards for foreign risks and considered that they were acceptable by applying the risks of selected domestic hydrogen stations.

  • This study analyzed the health risk behavior of Korean college students by comparing them based on the college location (Seoul vs. non-Seoul). Converging analyses of health risk behaviors (drinking behavior, sex, suicidality) and health risk factors (mental health, stress) were attempted. The results showed the 23% of students were at risk of serious drinking problem, and the 52.6% of students consumed alcohol once in every other week or more often. In case of the sexual behavior, 40.6% had sexual experience. Importantly, the 25.4% and the 20.3% of college students in Seoul and non-Seoul area, respectively, had two or more sexual partners. Also, students in non-Seoul area had a tendency of the higher level of suicidality, and the lower level of mental health. Overall, the self-respect score was the only statistically significant factor showing the Seoul/non-Seoul difference. These results may be able to intervene the health risk behaviors of college students.

  • 이상적인 GIS 예방진단 장비라 한다면 최소의 비용과 규모로 설치되어 결함은 빠짐없이 수 있어야 하며, 검출된 신호가 결함신호인지 잡음인지를 명확히 식별하여 필요한 정보만을 운전자에게 전달하여야 한다. 즉, 검출된 신호가 결함에 의한 것이라면 결함의 종류와 결함의 상세위치, 위험한 정도, 후속 필요조치 등에 대한 정보를 운전자에게 제공할 수 있어야 한다. 그동안 국내에서는 이상적인 기술목표를 향하여 꾸준히 연구해 왔으며 이제는 센서기술이나 센서 배치, 신호해석기술, 시스템 설계 제작기술, 시스템 운영 등에서 세계적 수준에 도달했다고 볼 수 있으나 외국에서도 마찬가지이기는 하지만 위험도 평가분야는 아직은 미흡한 상태이다. 현재 산업계와 학계, 연구계에서 연구개발을 활발히 하고 있으므로 수년 내에 만족할 수준까지 도달할 수 있을 것으로 전망된다.

  • This study analyzed the state of battered women who drink at a dangerously high level and the factors that influence their hazardous drinking in order to promote their safety and their healthy adjustments. The researchers utilized the data from "Analysis of the Effectiveness of Intimate Partner Violence Offenders Correction and Treatment Program" funded by Ministry of Gender Equality, and thereby, sampled 124 battered women for interview over phone. The results of applying the WHO's standard for hazardous drinking based on frequency and quantity calculations showed that 15.7% of survey participants were classified as hazardous drinkers, either currently experiencing or having the risk of experiencing problems related to drinking. The result of carrying out a logistic regression analysis to identify the factors that influence hazardous drinking showed that household income and self-blame were factors that exerted statistically significant influence. Based on these results, clinical and practical intervention plans for helping battered women who drink hazardously were discussed.

  • Owing to the established international standards for reliability and safety management of railways and the third-part conformity assessment implementation, quantitative risk assessment focusing on communication system related to railway safety has being implemented. The quantitative risk assessment starts from the establishment of quantitative RAMS requirements; the risk has to be maintained under an acceptable safety level. This paper introduces the risk assessment process based on international standards ; risk assessment was conducted using failure data for railway facilities for about 5.5 years. In addition, based on the results, a scientific risk management method for railway facilities is suggested.
