In 2009, the Korean international construction industry showed a great performance, totaling 49.1 billion of contract and then this achievement has been considered a key milestone presenting that the international construction industry is one of the primary export industries of Korea. However, because of the construction firms' equalized levels of technology and price competitiveness, the competition among bidders is becoming more intensive. Moreover, this changing market circumstance leads construction firms to apply for bidding with the lowest price that could not meet the expected profitability of a project. Therefore, to develop various strategies based on project characteristics becomes one of the critical capabilities that construction firms should possess. Based on these motives, this study is aimed to investigate associations among number of bidders, contract award rate, profitability on international projects. For the correlation analysis, a set of data is structured by collecting all projects ranging from 1993 to 2009, excluding projects funded by official development and domestic funds. The number of bidders were grouped depending on project characteristics such as market regions, project types, bidding types, and order organization types. As the result of correlation analysis, contract award rate increases as the number of bidders increase, but the relationship between the number of bidders and profitability is negative. Understanding the correlations among variables can be employed in developing strategies to improve construction firms' competitiveness in the international construction market.

PCB는 수십개의 주공정과 보조공정으로 구성된 제품으로 동일한 생산라인에서 로트 단위로 다품종 혼류 생산되고 있다. 따라서 PCB 제조라인에서는 많은 공정수, 높은 불량률, 다양한 공정설비 및 빈번한 설비고장, 중소기업의 낮은 설계 및 생산기술력, 빈번한 수주 변경 및 다품종 혼류, 긴급 수주 등과 같이 제조원가를 증가시키는 다양한 교란요인들이 항상 발생하고 있다. 본 연구에서는 생산성, 품질 등을 고려하면서 리드 타임을 단축하기 위하여 TOC DBR 기법을 개선한 2개의 DBR 개념을 도입하여 성공적으로 리드타임을 개선한 사례를 소개하고자 한다.

In the construction industry, bidding competitiveness is the most basic and important competence of the company. Bidding competitiveness comes from competitive advantage, but the strategy of the company to capture bidding competitiveness varies with the characteristics of the project. In particular, overseas construction is where uniqueness of the construction industry and the specificity of international business coexist. This study analyzes the bidding success ratio and the level of bidding difficulty by project characteristics with 12,952 overseas construction bidding cases. Consequently, it was found that the bidding success ratio of Middle East and North Africa (MENA) and civil engineering was the lowest in each group of project characteristics, and therefore the level of bidding difficulty is high, respectively. In addition, it was confirmed that the bidding success ratio of small size or short duration project was relatively high, and the bidding success ratio of both the negotiated bidding in the bidding method group and the private sector in the client type group was respectively high. However, Kruskal-Wallis test in contract type and period shows that there is no statistically significant difference in the bidding success ratio by group.

국내 전력산업의 성장률 저하 및 민간부문 전력시장 참여 확대등으로 국내 전력산업은 성장동력 창출이 절대적으로 필요해졌고 매년 12%이상의 전력설비 증대에 필요했던 다양한 기술과 경험을 계승하기 위해서도 전력산업의 해외시장 진출은 시대적 과제가 되었다. 특별히 송변전 분야는 발전이나 배전부문에 비하여 상대적으로 투자규모가 작으나 다른 분야에 비해 경쟁력이 작고 손실률 저감 등 우리 산업계가 가지고 있는 강점이 우세하여 아시아, 중동, 아프리카, 남미 등 전력산업 발전 가능성이 높은 개발도상국가로의 진출 가능성이 매우 높다. 이에 단순한 프로젝트 개발이 아닌 전략적 접근을 통해 해외프로젝트 발굴에 나선다면 해외시장 개척에 우위를 점해 향후 블루오션을 꿈꿀 수 있을 것이다. 성공적인 송변전분야 해외프로젝트 수행을 위해서 그동안의 경험을 바탕으로 한 제1단계 교육사업 및 진단사업, 제2단계 기본설계등 컨설팅, 제3단계 건설 프로젝트 수주 및 자재 수출등으로 전략적 수행방안을 제시하여 송변전 분야 해외 프로젝트 진출 활성화에 도움이 되기를 기대한다.

공공부문의 SW에 대한 사용자의 기대 및 정보화 요구에 부응하기 위하여 그동안 국내에서는 수많은 SW 시스템들이 개발되어 왔으나, 개발 과정에 대한 체계적인 관리 방법이 미흡하여 발주자가 복잡한 SW 발주과정을 추진하기 어려우며 SW 개발자에 대한 관리 통제수단이 미흡한 실정이다. 또한 발주자의 전문성 결여로 수주자인 개발업체에 과도하게 의존하는 업무 추진과 수발주자 간의 불명확한 업무 인식으로 상호 불신이 팽배한 가운데 공공부문 SW사업의 완성도 및 성공률이 저조하여 낮은 품질의 정보시스템 인수 등 사업 실패율이 높아지고 있다. 본 논문에서는 이러한 문제점을 해결하고 개선하기 위해 발주${\cdot}$관리 프로세스 확립과 이에 대한 적용을 중심으로 체계적인 SW사업 발주${\cdot}$관리 프로세스 확립과 이에 대한 적용을 중심으로 체계적인 SW사업 발주${\cdot}$관리 프로세스 개선방안을 제안한다.

Overseas construction orders of domestic companies had been increased significantly in a short period from $10.9 billion in 2005 to $64.9 billion in 2012. However experts are concerned that quality of growth will not support quantitative growth. This study suggest concentrate competencies for not only winning in bid but also successful execution of domestic companies. 4 Steps which are Pre-Marketing, Bid-Preparation, Bidding, Contract Phase are defined for competency assessment. After drawing specific tasks by phase, survey asking importance and capability of the tasks to the person in charge of bidding and site was conducted by utilizing Likert 7 point scale. According to the result of IPA analysis, domestic construction companies need to ensure internal competencies; Project risk review, Bid team organization, and external competencies; Client needs grasp, Localization strategy, Cooperation establishment. Hearafter domestic construction companies will be able to utilize the result of the study for setting bidding strategy for winning in bid and improving earning rate.

In spite of economic slump, the Real Estate PF(project financing) market competes for receiving large project orders. While the project is successful, the Real Estate PF still guarantees a high benefit ratio. But the initial stage of the project involves many risks. There are many financial, constructional, legal, and other risks. After searching for possible risks, we must consider a management plan. This study executed a question investigating risk factors and management plans. Those who have studied for 3 or more years have concluded that the question objects are developer, construction company, and financial institution staff. The main management plans take actions for proper benefit rate security and loan repayment. This study has also been verified through the actual case. The study results will help solve the Real Estate PF project's risks.

Bronchiolitis obliterans organizing pneumonia(BOOP) is a type of diffuse interstitial lung disease that has emerged in the past decade as an important cause of acute respiratory illness in adult. Clinically, the entity usually starts with a subacute influenza-like illness, followed by cough, progressive dyspnea, and weight loss. Organized inflammatory polypoid materials predominantly affecting distal bronchioles, alveolar ducts, and peribronchial alveolar spaces are a key pathologic findings. BOOP is characterized by a good response to glucocorticoid and an excellent prognosis. However, there is a subset of BOOP who presents with a fulminant course leading to death or chronic severe fibrosis with marked impairment of lung function. Recently, we have experienced a case of rapidly progressive BOOP, diagnosed by open lung biopsy and showed a reluctant response to corticosteroid.
