Even though domestic construction companies are expanding into overseas construction markets, the profitability of overseas project are decreasing and finally some biggest domestic construction companies recorded heavy deficit one after another in 2013. Contract management, which is very deeply related to profitability, is the most difficult area to domestic construction companies, especially in Middle East and Asia where they have the highest market share and a high level of contract management is required. The purpose of this study is to assess their contract management competences to help them improve contract management skills and strategies. First, we defined the overseas project contract management process and selected competences from the each process stage. Then, we conducted a survey with overseas project experts. For considering their competences from various angles, we divided survey groups into domestic construction groups and other groups (Contract consultancy agencies and Construction research institutes) to understand the internal and external perspective of the domestic construction companies' contract management competences. The results of survey was analyzed by using paired samples t-test, Borich Needs Assessment Model and Independent t-test. We expected that the results of this study could contributes to establish strategies for enhancing the domestic construction companies' contract management competencies.

최근에 많은 기업들은 XML 메시지 기반의 분산 환경에서 이기종 간의 표준으로 자리잡고 있는 웹 서비스를 도입하여 B2C 뿐만 아니라 B2B에 거쳐서 기업과 기업간 동적인 비즈니스를 수행하고 있다. 하지만, 웹 서비스의 도입이 성공적으로 이루어지기 위해서는 차별화된 서비스 품질을 보장해 주어야 한다. 현재 대부분의 웹 서비스에서는 메시지에 대하여 차별화를 두고 있지 않으며, 기존의 웹 서버들은 웹 서비스 제공자와 사용자간에 체결된 서비스 수준 계약에 대한 품질 요소들을 적절하게 반영하지 못하고 있다. 본 논문에서는 차별화 서비스에 사용되는 응용 수준에서의 적합한 품질 요소를 분석하고, 이러한 품질 요소를 이용하여 웹 서비스 메시지를 처리하는 프로세스에 대하여 서비스 수준 계약을 최대한으로 만족시키기 위하여 동적으로 우선순위를 할당할 수 있는 스케줄링 기법을 제안한다.

잘 정의된 인터페이스를 통해서 의미있는 서비스를 유도하거나 기술하는 소프트웨어의 식별가능한 조각인 컴포넌트를 개발하기 위한 방법론은 최근에 주목받고 있는 부분이다. 컴포넌트 기반 개발은 컴포넌트를 개발하기위한 단계와 이를 바탕으로 하나의 애플리케이션이나 시스템을 구축하는 과정이 병렬적으로 진행되는 프로세스가 특징적이다. 이러한, 단위 기능의 요소로써 컴포넌트는 새로운 요구사항에 대한 대치가능성이나 서로의 계약을 통한 조합이 가능한 것은 통합(integration)에 대한 개념이 기반이 되고 있다. 본 논문에서는 상이하게 개발된 컴포넌트 통합의 전반적인 개념을 소개하고, 단일한 컴포넌트의 통합과 통합된 컴포넌트 군을 재 통합하는 메커니즘을 정의한다. 또한, 이에 따른 컴포넌트 기반 개발의 전반적인 프로세스와 통합에 관련된 로직을 정의함으로써 체계적으로 컴포넌트를 개발할 수 있도록 도움을 주고, 컴포넌트 통합에 의한 재사용성과 효율성을 높이고자 한다.

방산물자의 품질은 국가 방위의 기본이 되며 이를 사용하는 병사들의 사기와 직결되어 있다. 이러한 방산물자의 품질보증은 어느 한 기업, 한 기관의 노력으로 달성될 수 있는 문제는 아니다. 소요제기, 연구개발, 계약, 양산 및 배치운영단계에 관여하는 모든 기관 및 부서가 서로 유기적으로 연결되어 공동의 품질목표를 향해 협력하고 나아갈 때 가능한 것이다. 획득관리의 전 시스템과 프로세스의 품질이 방산물자의 품질을 결정하고 있는 것이 사실이다. 그러나 획득관리 시스템 전체의 품질문제는 보다 광범위한 조사와 연구가 있어야 할 것이다. 따라서, 이 글에서는 양산단계의 품질보증활동을 중심으로 발전방향을 모색해 보았다.

최근의 정보통신 기술의 급격한 발달과 인터넷 사용의 폭발적인 증가, 기업의 인트라넷/익스트라넷의 도입으로 인터넷 환경에서의 비즈니스 응용 프로그램의 개발이 다양해지고 있다. 본 논문에서는 기업에서 조달 업무의 투명성과 신속성 및 인터넷을 통한 수요 기관 및 공급 업체간의 글로벌화를 이룰 수 있는 비즈니스 응용 프로그램으로 웹 환경에서의 전자 입찰 시스템의 설계 및 구현을 다룬다. 본 논문에서 설계 및 구현된 전자 입찰 시스템은 구매, 입찰 및 조달 프로세스로 구성되어 있으며 전자 입찰 시스템에서 입찰 가격이나 계약의 보안 및 인증을 위해 PKI 기반의 전자 서명 방식을 사용한다.

If project time extension were required in the construction projects, either liquidated damages or extension costs should be applied according to causation of the schedule delays. However, in actual cases it is not applied so far according to the contract conditions. The reason why this situation happened Is that function of the present planning and scheduling is not working feasibly. The CPM schedule could not provide a proper solution for apportioning responsibility for the schedule delays. This situation could be considered as breach of contract and will cause potential disputes for schedule delay. Therefore, in this research process based contract administration model for construction delay claim is proposed to prevent schedule delay and solve the claims. The model is based on pro-active management for causation of delay to provide apportionment of responsibility and written evidences.

The system engineering should be actively applied to successfully develop a complex and advanced weapon system, because the system engineering uses a multidisciplinary approach. Therefore, this study proposed a system engineering process for a successful weapon system development. According to the national standard policy, an IPT aspect system engineering standard must adapt the ISO/IEC/IEEE 15288. It also asks for tailoring with considering the IPT characteristics as a weapon system acquisition institution. The IPT aspect system engineering process to acquire a weapon system can be expressed with 3 process groups (Agreement, Technical Management, Technical) and 20 processes. There was a need for an institutional framework to hire retired experts from related organizations as consultants to apply the low-cost and high efficiency system engineering in the weapon system acquisition field.

This study represents construction progress management model based on quality inspection process in addition to cost-schedule integration. Quality inspection process cycle, resource estimate as progress measurement parameter, hierarchical structure of schedule, and inspection lots linking quality inspection to resource estimate are addressed as four main information areas. The authors established several process models to give a structure and correlations among information elements on each of these areas. Applying the process models proposed, an information system was implemented and utilized for nuclear power plant construction. It reveals that the system achieves accurate and objective progress information in near real time with significantly reduced time and effort as well as administrative efficiencies from making quality inspection process online.

This study evaluated the process of software quality assurance about the initial product in a weapon system. The software quality assurance of the initial product was insufficient before this study. Therefore, the process of the software quality assurance about the initial product in a weapon system is suggested. The process has three parts. First, the completeness of computer files, such as source code and execute files, were checked. Second, the suitability of the software technical data was checked. Finally, the connectivity of software technical data and the Korean defense specification were assessed. Overall, there is a need to toughen the software quality assurance in the research and development step and achieve early stabilization of mass production by preventing the problems that prevent the production of a product due to the insufficient software technical data.

This study will explore the possibility of applying process innovation as a public library for business innovation. In order to do this, the study defines the concept of process innovation through the literature review. According to survey and focus group interviews with librarians working for public libraries, this study will organize work done at libraries into the following categories: acquisition, resource management, user management, user services, programs, volunteer management, marketing, library computerization system, facility management, general affairs and statistical management. In addition, through face-to-face surveys with librarians working for public libraries it is confirmed that there are issues within acquisition, user management, and applied process innovation. In response to these issues a new process has been developed. Using this new approach, book contract procedure and requests for book related work could be improved and optimized. In the user management section, the study analyzes the requirements and subscription procedures for members through a website survey of 30 public libraries in the United States and then provides an improved system through process analysis of the membership process of Korean public libraries. It is expected that the new system will contribute to improvements in user satisfaction as well as improvements in library workflow.
