The e-marketplace is a virtual marketplace where buyers and sellers meet in order to conduct transactions through the intermediation of market-makers. For the success of an e-marketplace, it is crucial for the market-maker to induce both buyers and sellers to make active transactions in it. However, their participation is frequently deterred by potential risk factors caused mainly by the inherent, structural complexity of the e-marketplace. Therefore, it is a critical challenge for the market-maker to identify and manage the transactional risk perceived by both the buyers and sellers. In this paper, we investigate the sources of buyers' and sellers' perceived risks and their mitigating factors in the e-marketplace. Specifically, we derive an analysis framework based on the economic theory of agency relationship. The framework includes four sources of the risks(perceived information asymmetry, fears of seller opportunism, fears of buyer opportunism, and concerns about market-maker's role incompleteness) and five mitigators of the risks(website informativeness, trust in market-maker, trust in seller, product diagnosticity, and social presence). Then, we empirically verify the framework through a case study on four successful e-marketplaces, and provide implications and strategies for the market-maker to effectively manage the transactional risks.

Purpose: This study was undertaken to investigate bio-medical and behavioral risk factor of stroke according to the level of blood pressure among the prospective tele-health users. Method: A descriptive study was conducted using interviews with a structured questionnaire. Of the households in the village, 24 households were selected for inclusion in the study. Among all of the residents from these households, a total of 48 residents who completed all the blood tests as well as the questionnaire. Results: Among bio-medical risk factors including demographic characteristics, physiologic variables, and health history, only triglyceride(TG) was significantly different among normal, prehypertension, and hypertension groups(F=3.78, p<.05). However, regarding behavioral variables, those who were classified as prehypertension and hypertension group reported more frequent drinking, those who were in prehypertension group reported highest scores of stress and lowest frequency of exercise, and those who were in normal and hypertension group showed higher scores of interest on health and lower scores of perceived seriousness of disease and health knowledge than those who were in prehypertension group. Conclusion: Identification and implementation of modifiable risk factors of stroke according to the level of blood pressure are crucial for health care utilizing tele-medicine.

This study investigated the association between depression and oral health and the factors influencing depression in adults. Data on 13,199 people (male 5,793, female 7,406; age ≥19 years old) were extracted from the Korean National Health and Nutrition Examination Survey VIII (KNHANES VIII) (2016~2018) and analyzed using frequency, percentage, an x² test, a T-test, and logistic regression analysis. Depression was defined as either a medical diagnosis or a score ≥10 on Patient Health Questionnaire-9. The probability of depression was found to be statistically different for general characteristics, such as gender, age, school grade, income, and drinking. The logistic regression analysis showed that the independent variables, general health awareness (OR=9.094, 95% CI 7.139~11.585) and oral health awareness (OR=1.936, 95% CI 1.465~2.560), were associated with depression, and speaking discomfort, chewing discomfort, oral pain (within 1 year), and prosthesis were found to increase depression probability. The depression probability was also was found to significantly increase by 1.81 times if brushing frequency was less that once a day, if people used dental floss (OR=1.42), and had to have an oral examination (OR=1.31). These results indicated that oral health and oral health behaviors are associated with the depression, with the influencing factors having oral health and behavior-related characteristics. Therefore, proper oral health and oral health risk factor behavior management programs should be developed to assist in reducing depression.

산업현장에 앗차 위험이 지속되고 있다. 그러나 근로자들은 너무나 앗차 위험 행동에 익숙하여 무감각하게 지나쳐 버리고 있다. 이러한 의식 구조 속에서는 안전이 활성화 될 수 없으며 사고 위험으로부터 헤어나지 못하는 기업이 될 것이다. 산업현장에서 중대재해가 발생되고 나면 신경을 별로 쓰지 않은 곳에서 발생했다고 말한다. 대수롭지 않게 묵인한 것이 대형재해로 싹트기까지는 오랜시간의 앗차경험을 겪어왔던 결과치다. 근로자들의 전사적인 안전의식을 강하게 느끼고 인식하여 안전행동을 추진하는 기업은 이와 같은 유사재해도 사전에 제거할 대응 자세가 갖춰지게 될 것이다.

This study aimed to identify the risk factors for cardiovascular disease (CVD) among age groups using the Framingham risk score (FRS). The research design used was a cross sectional descriptive study using the Sixth Korean National Health and Nutrition Examination Survey from 2013-2015. Data from 5211 men, between the ages of 30-74 was analyzed. After adjusting for age, the result of logistic regression analysis showed that obesity (OR=2.51 95% CI=2.05-3.07), physical inactivity (OR=1.71, 95% CI=1.39-2.10), heavy alcohol drinking (OR=1.33, 95% CI=1.09-1.62), and dietary fiber intake (OR=0.99, 95% CI=0.98-0.99) were presented as predictors of CVD. Obesity was considered to be a particularly important predictor of CVD for young and middle-aged men. This result will be used for developing intervention relating to lifestyle modification for young and middle-aged men.

인터넷의 발전과 함께 시스템 보안에 대한 절대적 필요성이 날로 증가하고 있다. 외부에서 HTML 페이지로 액세스하는 것을 제한하는 방법은 무엇일까? 인터넷을 통한 트랜잭션을 보호할 수 있을까? 해커의 침입을 막을 수 있는 방법은? 심지어 인터넷에 노출돼 있는 금융권에서도 그들의 가장 큰 위험 요인은 내부에 잠재해 있다고 밝힌다. 대규모 피해를 가져오는 원인에는 꼭 악의적 의도가 요구되지는 않는다. 단순한 실수라도 상당한 피해를 불러일으킬 수 있기 때문이다. 삭제된 데이터베이스 파일이 사고나 나쁜 의도에 의해 바로 거대한 문제로 이어질 수도 있다. 특정 시스템에 대해 사용자를 인증하고 행위에 권한을 부여하는 방법이 악의적인 행동을 막는 것보다는 훨씬 현실적인 대안이 될 것이다. 이같은 보안책은 각종 사고로 인한 피해를 막을 수 있도록 도와준다. 어떤 보안 솔루션이 내외부적 위험을 막을 수 있는지가 중요한 관건이다.

본 논문에서는 「중대재해처벌법」과 관련한 중대시민재해의 예방을 위해 BCMS(Business Continuity Management System) 운영체계를 활용하는 방안에 관한 연구이다. BCMS 운영 체계는 시민에게 잠재적인 위협 또는 해당 위협이 발생했을 경우 시민에게 중대재해를 미칠 수 있는 특정 원료, 제조물, 공중이용시설, 공중교통수단 등의 운영·관리에 미칠 수 있는 영향을 사전에 파악할 수 있다. 또한 이를 이용하는 시민과 종사자의 생명과 신체를 보호하고 유해8위험요인으로부터 안전을 확보하는 능력을 갖추어 중대재해를 예방하고 조직의 리질리언스을 확보하는 데 목적이 있다. 따라서 본 논문은 안전 및 보건 확보의 의무가 있는 모든 조직; 사업주, 법인, 경영책임자, 공무원 등의 특성에 따라 접목할 수 있는 BCMS의 PDCA(Plan-Do-Check-Act) 운영체계 설계를 활용하여 중대시민재해 예방 대안을 모색하였다.

The aim of this study was to investigate the relationship between the neurocognitive ability and the risk factors of non-contact anterior cruciate ligament injuries during landing in female recreational athletes. Thirty-two female athletes participated in computerized neurocognition test and motion analysis for drop vertical jump. Pearson's linear correlation analysis was performed to analyze the relationship between the raw scores of neurocognition test and biomechanical variables including 3D joint angle, moment, power, vertical ground reaction force, loading rate, and support time. There were correlations between the scores of neurocognition test and biomechanical variables as high the neurocognition score, it also increase landing strategies were used to maintain posture of the lower extremity. Therefore, the neurocognitive test might be used as a good screening method to detect the risk factors before injury.

우리나라 손해보험 업계의 경영실적을 보면 2003년부터 2007까지 5년간 연평균 1조 1,130억원의 당기순이익이 발생하였으나 이는 투자이익에 기인한 것이고 손해보험사업 본업인 보험영업 손익에 있어서는 연평균 5,218억원의 손실을 기록하고 있다. 이와 같이 손실이 발생한 원인은 손해율 증감에 따른 보험요율의 조정미흡, 손해율상승 및 사업비 증가 등의 요인이 있으나 근본적인 요인은 해외 출수재의 불균등과 과다한 해외출재로 인한 수지차의 역조현상에 기인하고 있다. 특히 화재위험을 담보하고 있는 보험상품인 화재보험과 재산종합보험의 출재보험료는 약3,670억원으로써 전체 해외출재보험료에서 가장 높은 30.8%를 차지하고 있다. 이는 방재기술(Loss Control)의 활용미흡과 방재기술에 근간을 두고 있지 못한 보험인수 정책 즉 언더라이팅(Underwriting)기법의 낙후 때문이라고 할 수 있다. 따라서 전통적인 보험 상품인 화재보험에서 보험인수시 물건의 위험도를 측정할 수 있는 화재위험도 평가기법이 필요하고 이를 근간으로 위험을 인수하고 보유의 규모를 결정할 수 있는 체계의 구축이 필요한 실정이다. 이에 본 연구에서는 특정물건의 화재보험 인수과정에서 건물에 내재된 잠재 화재위험의 고저 또는 양 불량을 판정할 수 있는 화재위험도 평가 모형을 개발한 후 이 평가 모형에서 산출된 화재위험도보유계수를 활용하여 보유금액을 결정할 수 있는 보험인수 모형을 도출 하였다.
