We analyzed risk factors of coastal gillnet fishers during fishing process and considered work safety measures to reduce safety accidents during fishing using a UWB (ultra wideband) based positioning system. The static position accuracy of the UWB based positioning system was 45 cm. When entering a port, there is a risk of falling overboard. When casting a net, there was a risk of falling overboard due to being hit by fishing gear or guards, or getting caught in a buoy line or sinker line. When hauling a net, there is a risk of getting caught between fishing gear and net hauler, and the risk of musculoskeletal disorders due to repetitive work over a long period of time. Most safety accidents during work on fishing boats are blamed on human errors of the fisher and skipper, but safety accidents occur due to a mixture of mechanical and equipment factors, work and environmental factors, and management factors in addition to human errors. Therefore, the 4E were presented as countermeasures against the 4M, which are causes of safety accidents, and the proposed measures were used to identify risk factors for operation process, comply with work safety rules, and ensure the wearing of personal protective equipments. We need to reduce safety accidents during work by making it part of our daily routine. These research results can be used in the future for optimal placement of fishing gear and fishing nets in other coastal industries where safety accidents occur frequently.

Background: Osteoprotegerin (OPG) plays protective roles against the development of vascular calcification (VC) which greatly contributes to the increased cardiovascular events in patients with chronic kidney disease (CKD). The present study aimed to find the non-traditional, kidney-related cardiovascular risk factors correlated to serum OPG and the effect of serum OPG on the arterial stiffness measured by brachial ankle pulse wave velocity (baPWV) in patients with the pre-dialysis CKD. Methods: We cross-sectionally analyzed the data from the patients in whom baPWV and the serum OPG were measured at the time of enrollment in a prospective pre-dialysis CKD cohort study in Korea. Results: Along with traditional cardiovascular risk factors such as age, diabetes mellitus, pulse pressure, and baPWV, non-traditional, kidney-related factors such as albuminuria, plasma level of hemoglobin, total $CO_2$ content, alkaline phosphatase, and corrected calcium were independent variables for serum OPG in multivariate linear regression. Reciprocally, the serum OPG was positively associated with baPWV in multivariate linear regression. The baPWV in the 3rd and 4th quartile groups of serum OPG were higher than that in the 1st quartile group after adjustments by age, sex and other significant factors for baPWV in linear mixed model. Conclusion: Non-traditional, kidney-related cardiovascular risk factors in addition to traditional cardiovascular risk factors were related to serum level of OPG in CKD. Serum OPG level was significantly related to baPWV. Our study suggests that kidney-related factors involved in CKD-specific pathways for VC play a role in the increased secretion of OPG into circulation in patients with CKD.

Objective : Low back pain (LBP) is a global health problem that affects the productivity of the patients. Several factors such as individual, occupational, and psychosocial factors increase the risk of LBP. However, only a few studies investigated those factors, especially in middle adulthood in Indonesia. Indonesia is a country with a young population that has been rapidly developing in recent years. This study was conducted to find out the factors associated with LBP in middle adulthood. Methods : This study is a cross-sectional observational analytic study using a convenience sampling method with a total sample of 3005 respondents. Data were collected using a questionnaire which was then analyzed using the chi-square test, Kolmogorov-smirnov, Spearman's Rank, and logistic regression test. Results : From the result of this study, it was found that the 12-month prevalence of LBP in middle-aged adults was 44,29%. Female (odds ratio [OR], 1.3; 95% confidence interval [Cl], 1.098-1.545; p=0.002), lack of physical exercises (OR, 0.87; 95% Cl, 0.794-0.959; p=0.005), high body mass index (OR, 1.09; 95% Cl, 1.009-1.187; p=0.002), stress level (OR, 1.26; 95% Cl, 1.088-1.458; p=0.002), and years of work experience (OR, 1.1; 95% Cl, 1.001-1.225; p=0.047) were determined as risk factors that significantly associated with LBP. Conclusion : LBP is quite common among middle-aged adults in Indonesia. Female gender, higher body mass index, lack of physical activity, stress level, and years of work experience were all potential risk factors for LBP in middle-aged adults. Middle-aged adults in Indonesia should be aware of LBP and avoid disabilities by identifying risk factors that may worsen LBP in the future.

IT프로젝트 관리에 가장 중요한 요소 중 하나는 위험 관리이다. IT프로젝트 수행 중 발생할 수 있는 위험을 예측하고 대처하는 것이 프로젝트 성공 여부를 결정짓는 중요한 요소로 작용하기에, IT프로젝트 위험 요인은 학계와 업계에서 꾸준히 주목을 받는 주제이다. 이에 연구자들은 우선순위를 포함한 위험 요인 체크리스트 도출, 위험 요인들의 원인 관계 분석 및 프로젝트에 미치는 영향도 도출 등의 연구를 수행하였다. 그러나 위험 요인의 발생 확률과 영향도를 동시에 고려하는 위험 노출도의 관점에서 IT프로젝트 위험 요인을 체계적으로 분류한 연구는 미비하다. 본 연구는 문헌 연구 및 IT프로젝트 전문가 인터뷰를 바탕으로 IT프로젝트 위험 요인 53개를 도출하고, 도출된 위험 요인을 위험 노출도 관점에서 조사하였다. 나아가 프로젝트 관리자 140명의 설문을 통해 얻은 데이터로 군집분석을 실시해 4영역(HIHF, HILF, LIHF, LILF)으로 구분된 IT프로젝트 위험 요인 분류체계 프레임워크를 개발하였다. 또한 IT프로젝트를 프로젝트 성격 및 분야별로 위험 요인의 노출도 및 우선순위를 비교 분석하였다. 본 연구의 결과는 IT프로젝트 관리자들의 효율적 위험 관리 전략 수립을 돕고 IT프로젝트 실패를 줄이는데 활용될 수 있을 것이다. 또한 위험 요인의 발생 확률과 영향도를 동시에 고려했다는 측면에서 학문적인 의의를 가진다.

In this paper, we identify risk factors that are likely to occur during the lifecycle of a new product development (NPD) project from the literatures, and identify the three objectives or three constraints that will ultimately be achieved for project success in the ICT industry : performance (scope/quality), schedule (time), and cost. Firstly, we interviewed the project experts to classify the risk factors according that the final project objectives are changeable based on scope/quality, time and cost budget constraints. Secondly, the survey for pairwise comparisons between the risk factors was asked to the project managers and members who had ever actually participated in the NPD projects of ICT industry to determine the priority ranks on relative importance using AHP (Analytic Hierarchy Process). The risk factors negatively affecting the goals of projects were analyzed by using the AHP respectively in four project stages during the life cycle of the project. The comparison of risk factors within each stage is a different approach unlike the literatures which have covered project's overall risk assessment. There is an advantage that risk management can be effectively performed with priorities according to each stage from the start to the end of the project. In other words, it is necessary to identify what risk factors will occur in each stage, and to have ideas at each stage with the priorities so that they can be mitigated and eliminated before actual occurrence. As a result, risks on scope & quality changes were found to be the most important considerations for initiative stage of NPD projects in the ICT industry, whereas in the final stage, risks on schedule (time) changes were the most important priorities. Among the ICT industry product categories, 'communication and broadcasting devices' and 'IT and communication based devices' generally have a high priority in terms of risks on scope & quality changes when initiating the project. At the closing stage of the project, however, considering that schedule (time) changeable risk is getting higher, these products tend to target at B2B market rather than B2C because the new products must be delivered and launched in time as customer firm required.

Many risk factors exist for chemotherapy-induced nausea and vomiting (CINV). This study utilized a multivariate projection technique to identify which risk factors were predictive of CINV in clinical practice. A single-centre, prospective, observational study was conducted from January 2007~July 2010 in Singapore. Patients were on highly (HECs) and moderately emetogenic chemotherapies with/without radiotherapy. Patient demographics and CINV risk factors were documented. Daily recording of CINV events was done using a standardized diary. Principal component (PC) analysis was performed to identify which risk factors could differentiate patients with and without CINV. A total of 710 patients were recruited. Majority were females (67%) and Chinese (84%). Five risk factors were potential CINV predictors: histories of alcohol drinking, chemotherapy-induced nausea, chemotherapy-induced vomiting, fatigue and gender. Period (ex-/current drinkers) and frequency of drinking (social/chronic drinkers) differentiated the CINV endpoints in patients on HECs and anthracycline-based, and XELOX regimens, respectively. Fatigue interference and severity were predictive of CINV in anthracycline-based populations, while the former was predictive in HEC and XELOX populations. PC analysis is a potential technique in analyzing clinical population data, and can provide clinicians with an insight as to what predictors to look out for in the clinical assessment of CINV. We hope that our results will increase the awareness among clinician-scientists regarding the usefulness of this technique in the analysis of clinical data, so that appropriate preventive measures can be taken to improve patients' quality of life.

Purpose: This study purposed to examine the disease-related knowledge level and compliance with good health behavior in patients with myocardial infarction according to the atherosclerotic risk factors. Method: The subjects consisted of 72 patients with myocardial infarction and the data were collected by interviewing the subjects with questionnaires and reviewing their medical records from September, 15, 1999 to July 31, 2000. Data were analyzed using the SAS program. Results: 1) With regard to atherosclerotic risk factors: of the subjects, 91.7% lacked regular exercise, followed by smoking (61.1%). 2) The average knowledge score of the patients was 19.7 and the average compliance score was 53.9. 3) There were no significant differences in the total knowledge scores according to the patients' atherosclerotic risk factors. 4) Non-diabetics were significantly higher in knowledge scores on domain of risk factors than the diabetics. 5) The overweight patients were significantly higher in knowledge score on domain of nature of disease than the normalweight patients. 6) The total compliance scores of the non-smokers were significantly higher than those of the smokers. 7) The total compliance scores of the patients who do regular exercise were significantly higher than those of the patients who forgo regular exercise. 8) The non-smokers were significantly higher in compliance scores on domain of diet than the smokers. 9) The diabetic patients were significantly higher in compliance scores on domain of smoking cessation than the non-diabetics. 10) Patients who do regular exercise were significantly higher in compliance scores on other domains than the patients who forgo regular exercise. Conclusion: According to the above findings, it can be concluded that intensive nursing care and education should be provided to patients who have atherosclerotic risk factors such as smoking, hypertension, diabetes mellitus, lack of exercise, over weight, or hypercholesterolemia to increase disease related knowledge level and to improve compliance with good health behavior.
