해상교통안전진단제도의 개정으로 인해 해상교통안전진단의 대상사업이 축소됨에 따라 안전진단대상사업에서 제외된 100미터 미만인 선박의 안전진단 결과 부두의 평면배치가 변경되는 등 안전진단제도의 맹점이 도출되고 있다. 또한 안전진단 시행이전에 사업이 승인되어 공사 작업 중에 공사구간을 운항하는 여객선이 통항시 위험성으로 인해 운항이 중단되고 있다. 홍도 방파제 안전진단에 따른 평면배치의 사례와 솔빛대교의 사례를 통해 특별안전진단의 필요성을 제안한다.

마이크로소프트(MS)의 윈도우 비스타(Vista, 이하 비스타)는 윈도우 XP의 뒤를 잇는 버전으로 06년 11월말 기업용이 출시되었고 2007년 1일 31일 개인사용자용이 출시되었다. 비스타는 이전 버전인 윈도우 XP에 비하여 한층 강화된 보안기능을 탑재하고 있어 인터넷 사용시 악성코드 감염 등의 위험이 많이 줄어들 것으로 예측되고 있다. 그러나 비스타에서는 하드디스크 전체를 암호화 할 수 있는 BitLocker 기능 등이 추가되어 포렌식의 관점에서 보면 기존 XP와 달라진 점이 다수 존재한다. 본고에서는 기존 XP와 비교하여 비스타에서 변경된 부분을 포렌식 관점을 중심으로 기술하고자 한다.

한국축산경제연구원과 축산신문이 지난 2월 코로나-19 이후 축산업 인식 및 축산물 소비행태변화에 대한 연구를 실시했다. 본 연구는 축산물에 대해 코로나-19 이전·이후 소비실태 및 인식변화를 조사하여 축산물 소비행태에 영항을 미칠 수 있는 소비 여건 및 소비구조 변호를 살펴보고자 하며, 코로나-19라는 사회적 위험이 주는 불안감, 두려움과 같은 부정적인 심리가 소비자의 소비심리와 구매행태에 어떤 영향을 미치는지 알아보고 축산업의 홍보 및 판매전략 수립에 도움을 주고자 한다. 이에 본지에서 관련 내용을 정리하여 지면을 통해 소개한다.

본 연구에서는 유로커런시와 외환시장의 초과수익률을 설명하는 여러 가지 모형을 검증하였다. 비록 Campbell-Clarida(1987)와 Lewis(1990,1991)는 이 시장에서 3개월물의 초과수익률에 대한 단일잠재변수모형을 기각할 수 없었지만 본 연구에서는 이 모형이 여러 포트폴리오에 대하여 기각되고 있음을 보여준다. 그러나 이 모형의 검증은 결합가정을 필요로 하기 때문에 모형의 기각원인을 찾는다는 것은 어려운 일이다. 기각의 가능성으로 세계 경제에 하나 이상의 위험요인이 존재할 수 있다는 것이 될 수도 있고 불안정한 상수가 원인일 수가 있다. 상수의 안정성검증에서 1979년 12월을 전후한 기간에 상수가 변하지 않는다는 귀무가설이 모든 포트폴리오에서 기각되었다. 따라서 양기간에 단일잠재변수모형과 두잠재변수모형을 검증하였다. 모든 포트폴리오에 대하여 1979년 12월 이전에는 단일변수모형이 기각되지 않았지만, 1979년 이후에는 체계적으로 기각되었다. 한편 두잠재변수모형은 양기간 모두에서 기각되지 않았다 따라서 위험요인에 변화를 주는 연방준비은행의 운영절차의 변화가 단일변수모형의 기각의 원인일 수 있다고 유추할 수 있다. 마지막으로 시간 가변적인 베타가 단일변수모형의 기각의 원인이 될 수 있는지를 검증하기 위하여 Harvey(1989,1991)에 의해서 개발된 모형을 적용해 보았지만 모형이 기각되었다. 따라서 유로커런시와 외화자산의 3개월물의 초과수익률에 두 잠재변수모형이 자료를 비교적 잘 설명한다고 볼 수 있다. 그러나 잠재변수모형의 검증은 자산가격결정의 일반균형이론의 검증도 아니고 검증력도 강하지 않기 때문에, 위험프리미엄을 설명해주는 단순한 실증분석으로 보아야 한다.

Based on a complex event processing technique, an event analysis method for Business Activity Monitoring(BAM) is developed to provide an early warning for on-going events so that process managers effectively detect and monitor potential risks prior to the completion of the events. In this study, process-based event monitoring procedures to extract events with significant risks are presented; Complex event patterns are defined from historical event log data and risks of events are evaluated based on the patterns. A process-based event monitoring architecture for BAM is also presented. The proposed method has been applied to a service process of a home shopping company.

Job creations through doing star-ups is the biggest issues for almost nations. This study explores the entrepreneurial university's rule for making job creations based on Smart specialization and entrepreneurial university perspectives. In order to the aims, this study reviews the previous literatures and examines the some Israel universities, which is Technion University, Hebrew university as well as government support policies. Technion University and Hebrew university have own technology transfer institutions composed of experts for technology transfer and doing start-ups by using technologies. Each institutions have own characteristics regarding technology transfer and doing start-ups. T3, which is technology transfer institution of Technion University facilitates the start-up by step-by-step supporting mechanism. T3 has been operating EIR which has focused on business and marketing. Yissum, which is technology transfer institution of Hebrew university has board members. they have crucial roles to success the start ups. they can reconciliate the conflicts between university and Yissum. Also they can participate the business activities as mentors. Start-up money will be supported for even sprout state technology if their technologies are a promising business. Risk sharing between universities and start-ups influences on the increase of success ratio in Israel when comparing to that of Korea.

This paper analyzes the relationship between the industry bank loan concentration and its risk using the Korean bank loan data. We focused on the construction and real estate industry which are controversial on the non performing loans. We used the construction or leasing real estate industry bank loan ratio of the corporate bank loan as the bank loan concentration proxies. The bank risk are measured as the equity capital rate or the size of non performing loans. According to the results of this research, the preceding bank loan ration of the construction industry or the leasing real estate industry decreases the non performing loans and increases the equity capital rate. The bank loan concentration to the specific industry may not increase bank risk. The bank loan concentration may decrease the information asymmetry and improve the screening abilities the non performing loans. We suggest that the bank loan concentration on the construction or leasing real estate industry in the Korean economy may not directly connected to the bank risk.

This study explores a changing social expenditure structure of welfare states on new social risks, using logistic regression analysis with Panel Corrected Standard Errors Model on panel data of 1997-2007 years from 27 OECD nations. The result of this study presents that social expenditure structures have been adjusted with new social risk structure due to trade openness, female employment rates, and child population rates. Greater trade openness, higher women's employment rates, and lower child population rates are, more social investment expenditures are than income security expenditures. Rates of employment in service industries and elderly population rates are not statistically significant on the change of social expenditure structure. This result does not imply a complete switch from demand-based to supply-based social policy, but somewhat reflects transitions of a social welfare system for changing economic and social environments in order to sustain welfare state economically.

This paper tests a correlation between degrees of operating leverage(DOL) and financial leverage(DFL). For an empirical analysis, this paper extracted information from financial statements of manufacturing companies listed in the Korea Stock Exchange. Data extend from 1990 to 2009. The DOL continued to increase until 1997, but decreased dramatically after the IMF financial crisis. However, the DOL has been at a higher level than companies of other countries such as USA and Japan. The DFL has been maintained at a much higher level, as expected. The empirical results indicate a positive correlation between the DOL and the DFL. To further investigate, we divide the whole sample into subgroups according to such management elements as asset size, IMF crisis. The results for sub-samples are different from those of whole sample. This indicates we need to incorporate specific managerial factors in order to correctly explain financial decision processes.

With growing concerns about ever-increasing anthropogenic greenhouse gas emissions, it is crucial to enhance preparedness for unprecedented extreme weathers that can bring catastrophic consequences. In this study, we proposed a stochastic framework that considers uncertainty in weather forecasts for flood analyses. First, we calibrated a simple rainfall-runoff model against observed hourly hydrographs. Then, using probability density functions of rainfall depths conditioned by 6-hourly weather forecasts, we generated many stochastic rainfall depths for upcoming 48 hours. We disaggregated the stochastic 6-hour rainfalls into an hourly scale, and input them into the runoff model to quantify a probabilistic range of runoff during upcoming 48 hours. Under this framework, we assessed two rainfall events occurred in Bocheong River Basin, South Korea in 2017. It is indicated actual flood events could be greater than expectations from weather forecasts in some cases; however, the probabilistic runoff range could be intuitive information for managing flood risks before events. This study suggests combining deterministic and stochastic methods for forecast-based flood analyses to consider uncertainty in weather forecasts.
