아웃소싱 시장의 지속적인 성장에도 불구하고 국내 아웃소싱 시장은 대규모의 계약이 이루어 지지 않고 있다. 아웃소싱의 위험요인이 아웃소싱의 활성화에 장애요인이 될 수 있다. 정보시스템 아웃소싱의 위험요인에 대한 연구는 아웃소싱 수준 및 성과에 영향을 미치는 요소를 중심으로 연구가 진행되어 왔다. 즉, 전략적 효과, 경제적 효과, 기술적 효과와 같은 이익에 대한 연구가 주류를 이루고 있다. 그러나 아웃소싱 위험요인에 대한 연구는 사례가 거의 없고, 성과에 미치는 영향에 대한 실증적인 연구는 진행되지 않고 있다. 또한 아웃소싱 위험요소의 경우 대체로 발주자 입장에서 연구를 수행하고 있어, 실제 수주하고 있는 수주자의 입장에서 위험요소를 분석한 연구는 없는 상황이다. 본 연구는 기존 연구에서 제시된 아웃소싱 위험요소와 국내 정보기술 아웃소싱 상황에 맞는 위험요소를 도출하고, 이들 위험요소가 유발되는 정도가 정보기술 아웃소싱 성과와 어떠한 관계를 가지는지에 대해 실증적으로 연구를 수행하였다.

The representative risk evaluation techniques of the marine traffic environment are the FSA, PAWSA, & IWRAP. For the development of these techniques, the risk factors suitable to the marine traffic environment should be selected & the assessment criterion of the risk factors should be provided. The risk factors were selected as the factors that relate both to the frequency of casualty & to the consequence of casualty because the risk was defined as the frequency of casualty times the consequence of that casualty on the existing techniques. But, the risk factors relate to the consequence of casualty are excluded because the risk is defined as the sum of the risk factors including the frequency and the consequence by factors on this study. The 20 kinds of risk factors to compose the risk are selected and classified into 5 categories according to similar nature through the analysis of preceding study on the classification of the risk factors. Finally, as the foundation of risk assessment model's development for domestic marine traffic environment, the practical assessment criterion of the risk factors are suggested.

정보시스템 구축 프로젝트 환경이 다양해지면서 다양한 소프트웨어 및 하드웨어의 도입이 검토되고 있다. 환경의 다양성이 증가함에 따라 프로젝트의 위험요소들이 늘어남에 따라, 프로젝트 성공을 위해 프로젝트 전반에 걸친 위험요소에 대한 관심이 높아지고 있다. 기존 프로젝트관리 측면에서의 위험요인에 대한 연구는 지속적으로 있어왔으나, 소프트웨어 관점에서의 위험요소에 대한 연구는 그 동안 부족했다고 판단, 기존 프로젝트 위험요소 정의를 기반으로 소프트웨어에서 정의된 위험관리요소에 대한 재정의를 통해 소프트웨어에 대한 위험요소 정의의 타당성에 대해 확인해 보고자 한다.

Since the destruction of World Trade Center the attention of the United States and the wider international community has focussed upon the need to strengthen security and prevent terrorism This paper suggests an analysis prior to risk factor and structure for anti-terrorism in the korean maritime society. For this, in this paper, maritime terror risk factor was extracted by type and case of terror using brainstorming method. Also, risk factor is structured by FSM method and analyzed for ranking of each risk factor by AHP. At the result, the evaluation of risk factor is especially over maximum factor for related external impact.

In this study, in order to select the element items for risk assessment for autonomous ships, a survey was conducted on the maritime traffic control workers and the risk assessment element items were analyzed. The top five element items for risk assessment were identified, and the detailed value of risk elements according to the size of the vessel could be confirmed.

해상에서는 선박의 안전한 항해를 위해 각종 항로 표지가 이용되는데, 과학 기술이 발전함에 따라 환경적 요소 등의 이유로 항로표지를 설지 할 수 없는 지역에서는 가상항로 표지를 필요로 하고 있다. 선행연구에서는 가상항로 표지의 최적 배치를 위해 선박 항해의 물리적 항해 제한 및 항해 장애물요소, 선박 교통 위험도 등을 격자 단위로 파악하였다. 이에 본 연구는 격자별로 나눈 해역의 위험도 지수를 통합하여 통합 위험도 평가 지수를 개발하고자 한다. 이에 요소별 가중치를 설정하고, 레이어를 통합한 뒤 위험도를 산정하여 통계데이터 기반 위험도를 평가하였다. 요소별 가중치 설정을 위해 위험도 레이어 통합 가중치를 설정하였으며, 실제 해역에 적용하여 위험도를 평가하였다.

To assess the risk of marine traffic environments, with high confidential level, the risk factors comprising it should be identified and the risk acceptance criteria should be also provided. Furthermore, the relative importance of each risk factor(the weight of each risk factor on total risk) should be analyzed because the risk is expressed as the sum of risk factors comprising it. The twenty kinds of risk factors and its assessment criteria were suggested for the domestic marine traffic environments by an examination of the existing risk assessment models on the previous studies. The relative importance of each risk factor was also analyzed through the questionnaire using analytic hierarchy process by the marine traffic experts on the same studies. Based on these previous studies, the risk was evaluated at the port of Mokpo and its approaches on this study. The port of Mokpo and its approaches were divided into four sectors for the comparative evaluation, the result of the comparative evaluation on four sectors showed that the risk of the Jeongdeung-hae passage is the highest due to higher risk level of some risk factors(water movements, complexities, tug boats, pilotage, VTS) than the other sectors. The result of this evaluation is in accord with the analysis results of the other studies using various qualitative or quantitative risk analysis methods at the same sea areas.

There is a growing need to apply TBM tunnelling method for the construction of underground facilities such as subways and utility tunnels in urban areas. Due to the variability and uncertainty of the ground, tunnelling in urban areas has various safety hazards which could cause damage to people and properties and it is very costly to recover from accidents. Therefore, it is very important to identify hazards from the planning and design phase and to establish risk mitigation measures. In this study, a total of 31 hazards affecting the stability of TBM tunnelling works in urban areas were listed from both the technical literature and correspondence with experts in tunnelling area. The importance and priorities of the hazards were analyzed by conducting Delphi technique, which is a decision-making method by consensus among experts. Finally, 12 hazards that satisfy the content validity criteria were settled and could be used as major control factors for accident prevention during TBM tunnelling works.

This study empirically examines whether income smoothing effectively contributes to consumption smoothing. Since international factor movement plays an important role for income smoothing across countries, net factor income across countries deserves more attention in considering income smoothing than attention having been paid by previous studies in the literature. Most of previous studies assume that net factor income has the same degree of effects on consumption as GDP. For the case of 12 EU countries during the period from 1999 to 2010, our empirical investigation observes that the response of consumption with respect to net factor income is severely lower than the response of consumption with respect to GDP, and further net factor income has ignorable effects on the consumption. This evidence implies that the income smoothing via international factor movement is less significant in contributing to the consumption smoothing. In the sequel, our finding suggests that legal and institutional process for transferring net factor income across countries should be eased further to improve contribution of income smoothing to consumption smoothing.
