Government agencies have many difficulties for the information system development and operation. One of the difficulties is a budget estimation. Each government agency suggests individually different estimation for the personnel expenses and IT infrastructure adoption costs in the same field of informatization promotions. The other one is the operation costs are increased exponentially in every year[42, 51]. Those difficulties make government agencies can not help adopting SaaS. In fact, most of IT consulting company and government agencies already recognized a variety of SaaS advantages. The most typical SaaS's advantages are cost reduction, Software rapid development and deployment. However, once government agencies decide to adopt SaaS, they can not avoid many problems and difficulties. There is no information in a detailed item in a budget. In those kinds of situation, there is no choice whether government agencies accept SaaS provider's suggesting adoption costs or not. Thus, we provide a sheet of SaaS adoption cost estimation to government agencies. To know the cost factors, this study uses TCO(Total Cost of Ownership)'s criteria. To give a management point, this study uses Gartner's Application development Life Cycle. In this study, the integration check framework which is SaaS adoption cost estimation makes government agencies possible to establish a adequate budget.

This study adopts diffusion of innovation theory and analyses product life cycle on two different information communication technology (ICT) products. One is telematics located on introduction and the other one is MP3 located on maturity. The analytical results were mixed. ordinary least square (OLS) result showed that adoption of MP3 player is affected by white noise error ($\varepsilon$) and telematics is influenced by innovation effect (p coefficient) rather than imitation effect (q coefficient) or white noise error. However, nonlinear least square (NLS) result showed that adoption of MP3 player is affected by imitation effect (q coefficient) rather than innovation effect (p coefficient). In addition, the ratio of imitation effect/innovation effect of MP3 player is larger than that of telematics.

Entering the fourth industrial revolution era, health technology is rapidly developing and the people's needs for medical services are gradually increasing. Establishing a life cycle management of health technology has emerged as a new policy agenda to cope with these changes. However, the management of health technology have been conducted without continuity and with several problems pointed out. Therefore, we suggest the reform agendas by stages to establish system for a life cycle management of health technology in the fourth industrial revolution era as follows. In the stage of development, it is important not only to provide research funding, but also consulting by professional about whole cycle of health technologies. In the phase of market entry, there are needs for enhance the system that would expand the early adoption for innovative technology and increase its effectiveness. After the spread of health technology to clinical settings, a reassessment and post management system should be established that have an institutional framework with strong price adjustment and exit mechanism. Furthermore, we hope that discussions will be brisk in macro perspective on the balancing of development in healthcare industry, health of people and national health insurance finance.

Competitiveness of service industry in Korea is relatively lower than OECD countries'. Korean government, therefore, has been trying to improve the competitiveness of service industry by accelerating information technology (IT) adoption. Even though most of factors of IT can be contributed to improve the financial performance, it may be affected differently among various industry types and life cycles of companies. Therefore, it is one of very important research issues to analyze the influential effect of IT considering industry types and organizational life cycles in service industries. The purpose of this study is to find out critical success factors of IT which influence financial performance considering different types and life cycles of service industries. We developed the model and identified key success factors of IT adoption as IT system quality, Information quality, IT maintenance, CEO support, IT education of organization, and IT competence of user. Additional analysis of moderating effect by organizational life-cycle and types of service industry are conducted. For data sampling 856 companies are participated and total 2,000 questionnaires are collected. Structural equation modeling method is conducted for statistical analysis. The results show that the model is valid and most of success factors of it are very useful for improving financial performance of service industries except organizational IT education. Moderating effect of industry types and organizational life cycles is valid but partially accepted. The results might be able to provide useful directions and guide lines of IT acceleration in service industries.

Recently, innovative medical services are fast emerging, which include customized medical services based on bio-informatics, composition of cure and well-being exploiting ubiquitous technology, hospital supply chain management using RFID, and so forth. However, conventional approaches for new service development hardly give us systematic model to analyze and produce creative medical services. Because most of them are static and concentrate on microscopic tools or techniques. Thus, it is highly desirable to suggest an integrative framework to organize the whole transformation process from technology to medical service. The objective of this study is to propose a medical service engineering model based on the dynamic innovation theory. The proposed model contains objectives of service system, strategies of hospital, stages, activities required to deal with medical service life cycle, which incorporates the acquisition of new technology, transformation to the product, penetration into market, and adoption of consumers. In addition, the usefulness and applicability of the newly proposed model are provided using catholic medical center example.

본 연구에서는 신제품 확산 모델 활용에 있어서 보다 적은 노력이 필요하지만 객관적이고 신속한 활용을 가능하게 만들어줄 모형을 제안한다. 기대주기 모델과 소비자 수용 모델이라는 이론적 배경을 바탕으로, 서지분석학과 초기 시장의 규모만으로 최대 잠재 시장을 추정해냄으로써 대표적인 확산 모형인 배스 모형(Bass model)에 필요한 주요 모수를 제공하는 방법을 제시했다. 모형의 예측력을 하이브리드자동차 사례를 통해 분석한 결과, 모형의 예측결과는 여러 가지 객관적인 정보를 통해 추정한 잠재 시장과 유사한 규모를 성공적으로 예측해 내어 모형의 활용 가능성을 확인할 수 있었다. 제안된 모형이 제공한 최대 잠재 시장은 다른 성장곡선모형에도 바로 적용 가능하다는 점을 볼 때 제안된 모형은 서지분석학을 통한 기술 확산 예측과 유망기술 탐색에 새로운 방향을 제시했다고 할 것이다.

Weapon effect is a key issue throughout the life cycle of weapon systems. Only when weapon effect is considered properly, Effects Based Operation(EBO), Effects Based Acquisition(EBA), and Effects Based Development(EBD) could be possible. Because the transfer of weapon effect technologies is restricted in most foreign counties, independent development is necessary. In this paper, framework of weapon effects calculator for hardened targets is proposed to meet the own development needs. It is designed focusing on running time, validation and expandibility by adoption of modular architecture. Required technologies for each module are identified, and unclassified ones are summarized.

As the functional and nonfunctional requirements of defence systems become more complex and precise, concerning about the systematic development of software embedded into the defence systems has become surged up. In order to develop more reliable and correct software, and to extend the life cycle of the developing software, adoption of some engineering technologies such as development process, methodology, CASE tools and documentation is essentially required. This paper introduce an approach to technical information management in embedded software development process, with an instance, airborne ECM system development project. Particularly, we suggest and explain how to guide the software development according to process and methodology, and how to generate technical documents using CASE tool.

기술의 확산 현상의 추세 및 발생 동인에 대한 정확한 이해는 새로운 기술을 예측하고 기술 혁신의 과정을 이해하는데 매우 유용하다. 본 연구에서는 기술의 진화 속도가 빠른 반도체 산업 32nm, 22nm, 14nm 로직 기술의 실증적 사례에 대해 기술적 성능 향상 및 경제성 지표를 고려한 정량적 추세 분석을 적용하여 기술 확산 현상의 추세 및 발생 동인을 분석하였다. 기술적 성능 향상을 고려한 기술 확산 곡선은 S곡선의 성숙기, 쇠퇴기 형태를 보였고, 경제성 기반 기술 확산 곡선은 학습효과곡선의 형태를 보였다. 기술 확산 곡선은 2년의 수명주기를 보였고, 기술 세대별 기술적 성능향상 또는 칩 제조비용의 변화 정도가 정량적으로 관찰되었다. 또한 제품구조혁신은 경제적 발생동인보다 기술적 발생동인이 더 지배적인 영향을 미침을 확인할 수 있었다. 본 연구결과는 첨단기술기반의 반도체 산업에 대한 기술 확산 현상의 추세 및 발생 동인에 대한 실증연구로 시사점이 있으며, 기술 예측 또는 기술 전략 수립에 활용될 수 있으므로 실무적으로도 의의가 크다.
