네트워크의 발달과 인터넷의 생활화로 컴퓨터 보안이 시대적인 중요문제로 부각하고 있다. 요즘 해킹으로 발생하는 재정적 손실은 특별하게 큰 사건이 아닌 경우에 언론에 보도되지 않을 정도로 만성적인 현상으로 인식되고 있으며 컴퓨터 범죄는 어느정도 사회현상의 하나로 여겨질 정도다. 그러나 컴퓨터 범죄를 퇴치하고 컴퓨터보안의 완벽성을 유지하고자 하는 기술적인 노력은 지속적으로 전개되고 있으나 컴퓨터 범죄는 오히려 늘어가고 있는 추세다. 이에따라 컴퓨터 범죄등 컴퓨터보안관리가 기술적인 수준에 머물지 않는 성격을 갖추고 있다는 인식이 최근들어 확산하고 있다고 할 수 있다. 이 논문은 이런 인식에서부터 출발해 새로운 개념으로 등장한 전사적 보안관리 (Enterprise Security Planning)와 컴퓨터 보안 위험 관리(Computer Security Risk Management)의 개념에 대한 이해를 중점적으로 제기했다. 또 컴퓨터 보안위험관리의 과정을 단계별로 검토해 컴퓨터 보안위험관리를 체계적으로 이해할수 있도록 제시했다. 마지막으로 본 논문은 전사적 보안관리와 컴퓨터 보안위험 관리차원에서 기업이 보안관리를 위해 갖춰야 할 새로운 흐름들, 예를 들어 보안관리자(Chief Security Officer) 제도와 보안보험 가입등 보안정책을 제시함으로써 컴퓨터범죄로부터 기업이 최대한의 안전성을 확보할 수 있는 경영전략의 틀을 제시했다.

건설업은 위험요소가 많은 업종 특성상 높은 재해발생율을 보이면서 정부에서도 많은 투자와 노력을 기울여 왔으나, 건설안전수준은 크게 향상되지 못하고 있다. 반면 선진국에서는, ISO에서 품질경영시스템과 환경경영시스템을 도입한 이후, 안전경영시스템에 대한 논의가 활발히 추진되고 있으며 안전에 관한 국가규격을 제정하는 등 안전활동이 크게 발전해 있다. 우리나라에서도 금년 7월부터 KISCO 2000프로그램이 시행되었지만, 건설업은 적용에서 제외되었다. 따라서 건설업에서의 안전경영시스템 적용 모델 개발 및 보급은 서둘러야 할 과제이다. 본 연구에서는 향후 건설업에 적용될 안전경영시스템 추진 모델을 개발하고 요건에 대응한 건설안전업무의 범위 및 문서화 체계작업, 그리고 추진과정을 제시하였다.

The risk assessment model is an important subsystem for effective establishment and operation of EMS (environment management system). In case of poor risk assessment long-term and large-scale failure expense might be brought. Managing policy, target and other indices based on risk assessment can guarantee successful EMS. In this paper, we aim at comparative analysis of various risk methods and propose an alternative risk assessment model for EMS.

This study calculated the cash flow using the financial information by fiscal year for 25 general hospitals and 23 hospitals, and analyzed the relationship between cash flow and net working capital. The analysis results showed that 73.3% of general hospitals and 83.3% of hospitals did not secure funds required for operating activities by fiscal year. The cash flow types that affect net working capital were expenses not involving cash outflows and changes in borrowings in general hospitals, and expenses not involving cash outflows and income not involving cash inflows and changes in borrowings in hospitals. However, in case of shortage of funds required for operating activities, at general hospital, due to expenses not involving cash outflows being high and income not involving cash inflows being low and resulting in increased borrowing, at hospital, due to expenses not involving cash outflows being high and resulting in increased borrowing. Therefore, for the stability of cash flow in management activities, the adequacy and relevance of the expenses not involving cash outflows need to be reviewed, and it will be necessary to review the appropriate internal policy measures to systematically and rationally manage cash flow in consideration of cash flows.

This study examined the effects of entrepreneurship and perception of entrepreneurial environment on business performance. In particular, this study analyzed the difference in the effect of each independent variable on the dependent variable by using the government's participation in the start-up support project as a moderate variable. In order to achieve the purpose of this study, the researcher drew the variables corresponding to entrepreneurship and the variables related to entrepreneurship awareness. Innovativeness and risk sensitivity were selected as variables for entrepreneurship, and market environment and product environment were selected as variables for perception of entrepreneurial environment. Based on the above variables the research model was completed including the degree of participation in the government's start-up support project as a moderating variable. The data for the empirical analysis were collected from start-up companies in Daegu in 2018. A total of 601 questionnaires were collected and 399 copies of the data were used in this study after removing the unfaithful answers. The results of the analysis showed that innovation had a negative effect on management performance, and risk sensitivity, market environment, and product environment had a positive effect on management performance. In terms of the moderating effect, in the case of innovation, the higher the participation in government support projects, the lesser the negative effect. Risk sensitivity and product environment showed a strong impact on companies with a lot of government support projects, and the market environment had a strong impact on those who participated less. This study confirmed the importance and necessity of entrepreneurship and perception of entrepreneurial environment that influence the management performance of entrepreneurs. It is also meaningful in that it deals with the practical effects of the government's start-up support project on the start-up performance.

Musculoskeletal disorders affect workers' safety in most industries, and forest operations are classified as a musculoskeletal burden according to the Occupational Safety and Health Act in South Korea. In particular, felling and delimbing operations are mainly conducted by manpower, and then, it is necessary to evaluate ergonomic risk assessment for safety of felling and delimbing workers. Three ergonomic risk assessment methods, such as Ovako Working posture Analysis System (OWAS), Rapid Upper Limb Assessment (RULA), and Rapid Entire Body Assessment (REBA), are available for assessing exposure to risk factors associated with timber harvesting operations. Here, three ergonomic risk assessment methods were applied to examine ergonomic risk assessments in chainsaw felling and delimbing operations. Additionally, exposure to risk factors in each method was analyzed to propose an optimal working posture in felling and delimbing operations. The risk levels of these operations were evaluated to be highest in the RULA method, followed by the OWAS and REBA methods, and most of the exposed working postures were examined with a low-risk level of two and three without requiring any immediate working posture changes. However, two significant working postures, including the bending posture of the waist and leg in felling operation and standing posture on the fallen trees in delimbing operation, were assessed as the high-risk level and needed immediate working posture changes. Low-risk work levels were examined in the squatting posture for felling operation and the straightened posture of the waist and leg for delimbing operation. Moreover, the slope in felling operation and the tree height in delimbing operation significantly affected risk level assessment of working posture. Therefore, our study supports that felling and delimbing workers must operate with low-risk working postures for safety.

With the penetration of the Internet and e-commerce, a 'crowdfunding' has emerged as a new way of financing. Crowdfunding has the advantage for a person to able to a simple way to finance her/his an innovative product or service from crowd. However, the success rate for crowdfunding projects is less than half. In this study, we introduce social exchange theory to explore the impact of trust and perceived psychological risk on the intention to participate in a crowdfunding website. Different from previous studies that have focused on a crowdfunding creator, we consider two different perspectives of a project creator and a project supporter. In addition, we compare perceptions of crowdfunding in different cultural contexts by conducting survey in two different countries Korea and Austria. Result shows that trust in recommendation and trust in website have different impacts on the intention to participate from two different perspectives. It also shows that perception of the quality and transparency of information provided by crowdfunding website has greater impact on trust in Korea than that in Austria. In case of perception of psychological risk, it has a negative impact on Austria's intention to create or support a project. On the other hand, it has relatively small impact on the intention to support and does not affect the intention to create a project in Korea.

This paper investigates the influence of stock-level left-tail risk, which is defined using Value-at-Risk(VaR) estimates of past one-year daily stock returns, in the expected stock returns in the Korean stock market. Our results are summarized as follows: First, monthly-constructed zero-cost portfolios that buy (shortsell) the highest (lowest) left-tail risk decile in the previous month exhibit an average monthly return (called left-tail risk premium) of -2.29%. Second, Fama-MacBeth cross-sectional regressions suggest that left-tail risk in the previous month shows significant and negative explanatory power over return in this month, after controlling for various firm characteristics such as firm size, B/M, market beta, liquidity, maximum daily return, idiosyncratic volatility, and skewness. Third, the stocks with larger recent month loss have lower returns in the next month. Fourth, the magnitude of left-tail risk premium is negatively related with lagged market-level volatility. These results support the hypothesis from a perspective of behavioral finance that the overpricing of stocks with left-tail risk is attributed to the investors' underreaction to it.

Horticultural facility farmers subscribe to crop accident insurance and insurance products secured by horticultural facilities in preparation for possible risks in the facility. Insurance is purchased to prepare for natural disasters such as typhoons, hail, frostbite, heavy rain, and strong wind damage covered by the product. In order to find out the effect of risk perception, which is a subjective perception of the risks of a given situation, on horticultural facility farmers' intention to purchase horticultural facility insurance products, the risk perception and insurance purchase intention were analyzed. A t-test was conducted to determine the impact relationship between farm size, insurance coverage, and risk perception, and multiple regression analysis was conducted to verify the effect of personal characteristics and behavioral factors such as subjective perception, reference group, media exposure, and compensation understanding. In addition, a three-step regression analysis by Baron & Kenny was conducted to confirm the mediating role of personal characteristics and behavioral factors in the relationship between risk perception and insurance purchase intention. As a result of the study, although there was no difference in farm size, it was analyzed that policy holders had a higher degree of risk perception than non-subscribers, and that compensation understanding had the greatest influence and subjective knowledge had the smallest influence. In addition, these four factors were verified to have a mediating effect on the relationship between risk perception and insurance purchase intention. These results are expected to provide practical help to the development and marketing activities of horticultural facility insurance products.
