Korea's overseas construction industry has been rather depressed by the weakened profitability as well as the sharp decrease of the market shares due to the lack of international competitiveness and the declined international market following the outbreak of Iraq war. There exist a lot of various risks in performing the overseas construction, and especially EPC projects, which entail complicated process from different parts, also require a sophisticated procurement and management skill. Subsequently, to survive in the competitive international market, we need to establish strategies to select potentially profitable projects at the initial stage of bidding process and to mitigate the high degree of risk exposures through contract negotiation and its adjustment. This research provides the profitability evaluation bases, with which overseas construction participants can forecast and analyze the risk more systematically, by eliciting profit-influencing factors from real overseas construction projects and structuring their cause-and-effect relationships. The profitability causal hierarchy structure describes the profitability factors' hierarchy in details and their interrelationships. It also enables us to find out critical factors directly related to profitability aggravation through a qualitative analysis. Ultimately, with this hierarchy structure as the base, the research will suggest how to develop the quantitative profitability forecasting model.

Since the concept of virtual currency called Bitcoin was announced in 2008, the blockchain technology, which is the basis of Bitcoin, is attracting attention as an important platform technology in the era of the 4th industrial revolution that can change our society in the future. Although Existing electronic financial transactions store and manage all transaction history at a reliable central organization such as government and bank, blockchain-based electronic financial transactions are composed of a distributed structure in which all participants participating in the transaction store and manage the transaction history, it is possible to secure transaction transparency while reducing system construction and operation costs. Besides the virtual currency that started with bit coins, the technology of these blockchains has been extended in various fields such as smart contracts and document management. The key technology area of this blockchain is security based on proven cryptographic technology to make it difficult to forge and hack, but there are security risks such as security vulnerabilities in the virtual currency trading service, We will discuss security risks in using virtual currency and discuss countermeasures. Especially security accidents of virtual currency exchanges are occurring frequently recently, the damage of users who trade the virtual currency is also increasing, we propose security threats and security countermeasures against virtual currency exchanges.

Diverse stakeholders engaged in design, construction, and operation and maintenance of offshore plants typically operate heterogeneous plant 3D CAD systems. Engineering, procurement, and construction (EPC) companies are required to submit plant design result to the owner in the form of a plant 3D CAD model, as specified in the contract. However, because of the limitations of data interface of plant 3D CAD systems, EPC companies frequently perform manual remodeling to fulfill the terms and conditions of the contract. Therefore, comparison should be performed between the source plant 3D CAD model and the remodeled plant 3D CAD model to prove the validity of the remodeled plant 3D CAD model. To automate the comparison process, we have developed a system for quantitatively assessing the similarity of the plant 3D CAD models. This paper presents the architecture and detailed functions of the system. In addition, experimental results using this system are explained.

The objective of this paper is to discuss geographic information policies and strategies of British government and suggest effective policies for Korea National GIS project GIS that has been implemented geographic information infrastructures into public sectors and private markets for the last ten years. To obtain the research aim, this paper reviews the main factors of the Britain GIS project such as distribution structure and process of GI markets, government policies and strategies that are led by Ordnance Survey, most leading mapping agency in the UK. In conclusion, some issues have been explored with reference to the experiences of the Britain GIS projects. The first of these is the nature of geographic information and the second concerns the notion of the circulation policies of spatial data, and the last proposes Korea GIS policies and strategies for successful geographic information and spatial data implementation. The findings of the analysis of the Britain GIS development indicate that a shift began to take place from central government coordinate toward more extensive utilization of private and commercial sectors. This reflects both the increasing importance of geospatial data circulation in all levels of GIS stakeholders. Finally these discussions are particularly to be the issues where multi-agency collaboration of Korea government is concerned and can take the form of joint ventures by consortiums of both involving data producers and data users in order to increase commercial participation for value-added geospatial items, and to encourage both research and development sectors with low or free price policies.

The thesis examines genealogical study of various aspects to overcome lots of problems which come by when we execute SWIFTNet TSU BPO. Practical implications regarding the innovation of electronic trade infrastructure are as follows. First, the shipping documents in the SWIFTNet TSU BPO are directly sent to an importer by an exporter after the baseline is confirmed. With this process itself, therefore, the bank cannot secure the account receivable. When initiating the SWIFTNet TSU BPO deal, it is needed to set regulations on the bank's account receivable security in the contract. Second, the SWIFTNet TSU BPO should also have an institutionally unified sharing platform with security, stability and convenience. It other words, it is needed to develop services which meet e-payment paradigm and international environments through continued analysis on market changes and flow. Third, the SWIFTNet TSU is useful in terms of promptness, reduction of risk in foreign exchange payment, cost reduction. Therefore, the SWIFT should be perfectly united and linked among the banks, importer and exporter to make the SWIFTNet TSU more convenient in countries around the world. Fourth, the SWIFT should be approached from the aspect of expansion of network and creation of a new business model through analysis on these problems with a worldwide perspective. At the same time, it is necessary to build a cooperative system to share information and promote comprehensive management for efficient operation.

This paper examines the achievements and limitations of the Moon Jae-In administration's first-year policies on non-standard employment in the public sector of Korea. The most remarkable achievement was that the transition rate of non-standard to standard positions reached the highest historical level of 42.1 percent, mainly by including for the first time temporary agency workers as a target of those policies. There also have been many steps taken to relax the qualification for transition, reduce the number of exception clauses, and expand union participation. In contrast, policy measures to address problems of low wages and inequality were very limited and not significantly different from those of previous administrations. As a result, the success of the policy paradigm shift pursued by Moon's administration will be determined by how aggressive measures are being taken in the next policy steps to improve such problems of low wages and inequality.

Firms employ one of two stock repurchasing methods, either direct open market repurchase or indirect repurchase through trust contracts. Since these two methods have some regulatory differences, managers of firms may use a repurchasing method as a signal to convey the information to the market. Therefore, this study investigates the relationship between stock repurchasing methods and implied cost of equity of firms. The results show that there is a significant and negative relationship between stock repurchase announcement and cost of equity. In addition, the implied cost of equity for firms employing direct open market repurchase is significantly lower than those of firms that use indirect repurchase method. Overall, the market accurately reflects the information conveyed by two stock repurchasing methods into cost of equity of firms.

본 연구는 미국 오레곤주의 수산업 특성을 개괄적으로 살펴본 것이다. 먼저, 오레곤의 상업적 수산업을 역사적으로 살펴보면 2가지 주요한 계기가 있음을 알 수 있다. 첫째는 자급자족 차원에서의 연어생산을 수출품으로 변화시킨 연어통조림 생산기술의 발전이고, 둘째는 현대식 트롤어업이 도입된 점이다. 오레곤에서 주로 사용되는 어구ㆍ어법은 트롤, 채낚기, 연승, 통발, 형망 등이며, 생산어종은 연어, 게, 새우, 참치, 대구 등이다. 1995년 오레곤은 약 2억 4천 파운드의 수산물을 생산하여 미국 연안주중에서 6위를 차지하고 있고, 생산금액에서는 12위를 기록하였다. 한편, 양식업은 아직 성행하지 않아 그 생산품종 및 생산량은 미미한 실정이다. 그 주된 이유 중의 하나는 양식시설을 하기 위해서는 여러 관계기관의 허가를 필요로 하는 등 행정상의 절차가 복잡하기 때문이다. 오레곤의 수산자원관리는 우리나라에 비해 암계의 어획금지, 통발 등 정치어구ㆍ어법에 대한 인망일수의 제한, 조개류의 판매가능시간의 제한 등 몇가지 특징을 들 수 있다. 오레곤의 수산업관리제도(연안으로부터 3마일 이내)를 살펴보면, 아직 TAG제도를 도입하지 않고 있으며 생산요소역입제한방식이 채택되고 있다. 즉, 상업적으로 허용된 어종을 어획하려는 어업자는 등록절차를 필히 거쳐야 어업행위를 할 수 있으며, 등록수를 제한할 필요가 있는 특정한 어업(연어, 새우, 가리비 등)에 대해서는 행정관청으로부터 허가를 얻고 어업행위를 해야 한다. 즉, 허가어업은 등록어업보다 더욱 제한적인 어업행위를 말하며, 허가권에 대해서는 자유로운 매매양도가 허용되어 있다. 수산물의 마케팅시스템에 대해서는 우리나라에 지배적인 형태인 경매제도가 도입되어 있지 않다. 즉, 모든 수산물은 개인적인 거래계약에 의해서 유통된다. 다만 마케팅경로에 참여하고 있는 모든 구성원은 일정한 등록절차를 마쳐야 하며, 주내에서 거래되는 수산물의 일관된 통제나 관리를 위해 관계기관에 거래량을 필히 신고해야 한다. 우리나라의 중도매인은 주로 생산지의 수협(또는 내륙지 도매법인)과 도매상의 사이에 존재하나 오레곤의 중도매인은 마케팅경로 어디에든 존재하고 있다.

The purpose of this study is to analyze the adequacy of product qualification criteria through Monte-Carlo simulation and association rule analysis. We first surveyed the similar procurement systems, then we simulated the bid situation that randomly generated several vendors participated in a bid, and they obtained the score according to the product qualification criteria's judgement area. Then, the company with the highest score will win the bid, and further analysis was performed in terms of performance indicator and satisfaction ratio. The results of this study can be summarized as follows; Although the items related to the credibility accounted for the largest number items, it did not affect the actual bid results. It was analyzed that it is desirable to increase the allocation points in the area of business status and technical capability review than the current one.
