This paper proposes the FMEA-based model to avoid backdoor transactions when purchasers select suppliers for products and services. In the model, backdoor transactions consist of two categories: backdoor selling and maverick buying. Both of which influence negative effects on cost savings due to not only uncompetitive advantage but also unusable purchasing leverage by unethical and misbehavior of purchase requestors. For the risk evaluation based on FMEA, three and five risk types of backdoor selling and maverick buying are identified respectively. Current risk priority numbers(RPN) based on those risk types are calculated by three categories: occurrence, detection and severity. Six risk mitigation strategies and fourteen mitigation tactics are identified to improve current RPN. In order to validate the model, questionnaires are collected from fifteen companies and statistically analyzed. The analysis result shows that the model reduces backdoor transaction risks and has no differences in reduction of backdoor transaction risks regardless of the type of purchasing organization units and existence of purchasing procedures in the organization.

Purpose: To determine the degree of cardiovascular disease risk according to socioeconomic factors among midlife women in the community and thereby provide baseline data for the development of health promotion programs. Method: A total of 200 women participated in health screenings and a health survey. The survey was performed in November and December, 2006. The survey instruments included socioeconomic factors, health behavior (smoking and exercise), and family history. Biophysical measurement included BMI and blood pressure. Blood samples were drawn for glucose and total cholesterol tests. Results: The mean age was 52.5 years, 34.0% had received education less than 6 years, 70.0% earned a monthly income of less than \1,500,000, and 61.5% were homemakers. Cardiovascular disease risk was significantly different by age (BMI, systolic BP, and exercise), education (systolic BP), monthly income (T. cholesterol), marital status (smoking), and occupation (exercise). Most women had 2 or 3 cardiovascular disease risks. Older age, lower education, and lower income were significantly associated with increased cardiovascular disease risk. Conclusion: Efforts should be made to decrease the number and severity of cardiovascular disease risk factors for midlife women in the community by developing health promotion programs targeting to modify their cardiovascular disease risk factors.

Since the dehydration packages of offshore plant deal directly with oil & gas, there is a great risk of fire and explosion during operation. Therefore, this study performed risk assessment through HAZard & OPerability (HAZOP) for solid desiccant dehydration package that can remove water component of natural gas in offshore floating liquefied natural gas (LNG) production facilities below 0.1 ppmv. The risk matrix was determined by dividing the likelihood and the severity into five levels separately by asset, life, environment and reputation. The piping & instrumentation diagram (P&ID) of the dehydration package was divided into 9 nodes. Total 22 deviations were assessed in consideration of the adsorption and desorption conversion cycle. A risk assessment based on deviations revealed 14 major hazards. Three representative types of hazards were open/close failure of the control valve, control failure of the heater, and abnormal operation of the regeneration gas cooler. Finally, we proposed the installation of additional safety devices to improve safety against these major hazards, such as safety instrumented functions, alarms, etc.

Purpose: In Cambodia, noncommunicable diseases (NCDs) account for 64% of all deaths. A lack of risk perception of NCDs leads to poor measures of their prevention and management. This study aimed to investigate Cambodians' risk perceptions of NCDs based on the health belief model. Methods: A cross-sectional design was used, and using convenience sampling, participants included 200 Cambodians aged 40 years or older. A face-to-face administered structured questionnaire was used to assess demographic characteristics, health behaviors, and risk perceptions of NCDs. Results: Of the constructs of NCD risk perception, perceived severity (88.2%) and benefits (86.3%) were high, but relative to these, perceived cues to action (64.1%), barriers (63.5%), and self-efficacy (58.1%) were low. Conclusion: It is important to improve perceived self-efficacy in government health promotion, outreach, and improvement programs and to reduce perceived barriers through medical tests either by facility-based delivery or via outreach health services in Cambodia.

We proposed a new scoring system on software vulnerabilities, which calculates quantitatively the severity of software vulnerabilities. The proposed scoring system consists of metrics for vulnerability severity and scoring equations; the metrics are designed to measure the severity of a software vulnerability considering the prevalence of the vulnerability, the risk level of the vulnerability, the domestic market share of the software and the frequency of the software. We applied the proposed scoring system to domestically reported software vulnerabilities, and discussed the effectiveness of the scoring system, comparing it with CVSS and CWSS. We also suggested the prospective utilization areas of the proposed scoring system.

Purpose: The aim of this study was to evaluate the complications of open reduction and internal fixation of mandibular fracture with miniplates. Patients and Methods: A total of 134 patients who presented with 196 fractures were analyzed retrospectively. Complications were evaluated for factors such as age, the site of fracture, the severity of fracture, delayed operation, preoperative wound contamination, the site and disposition of teeth in the fracture line and midfacial fractures. Statistical analysis was used to compare complications to risk factors. Results: Of the 134 patients, 20 patients had some form of postoperative complications and complication rate was 14.9%. These complications included infection, plate fracture, malocclusion, wound dehiscence, nerve injury and nonunion. There was a significant correlation between complication rate and the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth(p<0.05). Conclusion: The occurrence of postoperative complications in the treatment of mandibular fractures was related to the severity of fracture, preoperative wound contamination and the site of the fracture and disposition of teeth.

FMEA (failure mode and effect analysis)is a widely used technique to assess or to improve reliability of product not only at early stage of design and development, but at the process and service phase during the product life cycle. In designing a service system, this study proposes a fuzzy service FMEA with the service blueprints as a tool which describes customer actions, onstage contact employees actions, backstage contact employees actions, support processes, and physical evidences, in order to analyse and inform service delivery system design. We fuzzified only two risk factors, occurrence and severity, to more effectively assess the potential failure modes in service. Proposed fuzzy risk grades are applied to Gaussian membership function, defuzzified into Fuzzy Inference System, and eventually identified the ranks on the potential fail points.

The risk ranking of food groups included the Korea Food Code is a potentially powerful means to prioritize food safety management strategies. Although the interest in risk ranking of food groups has been increasing worldwide, there was, until recently, no standard system in Korea for the risk ranking of food groups. This study was conducted to rank food groups using theoretically estimated comparative risk scores of 101 food groups included the Korea Food Code. These scores were estimated using the risk evaluation model, which focuses on 3 aspects, namely, exposure assessment, severity assessment, and consumption part. The results of this study revealed that the risk was the highest in the case of ready-to-eat (RTE) food items, followed by fish products and breads. Using this ranking system, we can identify the food with high risk scores and design risk management strategies targeted specifically at these items.

Objectives: The prevalence of metabolic syndrome has recently increased, Payments from the Korea Labor Welfare Corporation for compensation for mortality in workers caused by cardiovascular and cerebrovascular diseases have also increased in Korea in recent years. The association of metabolic syndrome and cardiocerebrovascular disease has been investigated by several researchers in recent studies, This study was conducted in an attempt to characterize the relationship between metabolic syndrome and Korean cardiocerebrovascular disease risk assessment, and to provide basic data to group health practices for the prevention of cardiocerebrovascular disease. Methods: Health examinations were previously conducted for 1526 male researchers at a private laboratory. The prevalence by age and the odds ratio of metabolic syndrome scores into the "cardiocerebrovascular risk group" (sum of low, intermediate, and high risk groups) of the Korean cardiocerebrovascular disease risk assessment were assessed, in an effort to elucidate the associations between metabolic syndrome and cardiocere brovascular disease risk assessment. Results: The prevalence of metabolic syndrome and inclusion in the cardiocerebrovascular risk group was 11,7% and 22.1% respectively. The severity of metabolic syndrome and cardiocerebrovascular risk assessment showed that individuals in their 40's and 50's were at higher risk than those in their 30's (p<0,001). The age-adjusted odds ratio of metabolic syndrome to cardiocere brovascular risk group inclusion was 5.6. Conclusions: An active prevention program for cardiocerebrovascular disease needs to begin in the 40's, as the prevalence of metabolic syndrome and the risk group of cardiocerebrovascular risk assessment peak in the 40's age group. The odds ratio between metabolic syndrome and the cardiocerebrovascular risk group was high, which indicates that metabolic syndrome scores should be utilized as guidelines during the consultation and behavioral modification program for the workplace prevention of cardiocerebrovascular diseases in group health practices.

Purpose: Diabetic foot ulcer is one of the most important diabetic complications because it increases the risk of amputations. Moreover, it lowers the quality of patients' life and increases the social medical expenses. Authors analyzed risk factors of intractable diabetic foot ulcer using retrospective study. Materials and Methods: From January 2007 to December 2010, 40 patients who could not achieve complete healing despite more than 12 weeks of proper management among who had been diagnosed and treated as diabetic foot ulcer at our hospital were included and evaluated retrospectively. We compared the risk factors between two groups who were finally treated by amputation and non-amputation. Results: The sample was composed of 31 male patients (77.5%) and 9 female patients (22.5%). Comorbidity including hypertension and hyperlipidemia were 77.5% and 80% each. By Wagner classification, 30 patients (80%) had ulcerative lesion over the grade 3. From bacteriology results, 29 patients (72.5%) had polybacteria infection. 35 patients (87.5%) had neuropathy and 26 patients (65%) had vascular stenosis at least one level. The mean initial ankle-brachial index and toe-brachial index were 0.982 and 0.439. In comparison between amputation group and non-amputation group, ulcer severity, number of stenotic vessel and initial ankle-brachial index/toe-brachial index had statistical significance. Conclusion: The most commonly risk factor of intractable diabetic foot ulcer was peripheral neuropathy reaching 87.5% of cases. In comparison with non-amputation group, ulcer severity according to Wagner classification, number of stenotic vessel and initial ankle-brachial index/toe-brachial index were demonstrated as a risk factor of amputation in intractable diabetic foot ulcer.
