본 논문에서는 특허분석을 이용하여 기술이 산업에 미치는 파급효과에 관해 연구하였다. 1990년과 1995년에 각각 우리나라에서 미국에 등록한 특허를 중심으로 산업별 특허등록건수와 특허 인용횟수, 기술혁신속도, 과학기술연계 등 특허인용지표를 활용하여 이를 산업별 부가가치와의 다중 회귀분석을 통해 기술의 집합체를 연구개발 할 경우 기술이 산업에 미치는 파급효과를 분석하였다. 결론적으로 특허등록건수와 특허인용횟수는 산업별 부가가치에 대해 각각 유의한 것으로 분석되었다. This paper considers the technology spillover effects on industries by analyzing patents. Registered patents in the United States from Korea in 1990 and 1995 are compared by quantity of registrations as well as patent analysis indices, namely, cites per patent, technology cycle time and science linkage. Several regression models between these indices as predictor variables and the value added of an industry as a dependent variable were investigated. The results show that the value added of an industry positively correlates to the number of patent registrations and cites per patent.

Recently, many organizations in various industries have introduced e-business for the purpose of adding value to their business. But, the e-business model has not existed before and so, it is difficult to analyze clear effectiveness. It frequently does not live up to an organization's expectations. It is due to an absence of environmental changes analysis in the new model, not by a new model itself. System Dynamics(SD) may provide effective results as a tool of analysis for the new model. This research shows the analysis of the effects of a simulated e channel model, which was expanded from existing channel modeling with actual data in basic materials industries. The results show average prices increasing by auction process on the e-market and an increase in sales. So, by increasing the speed of sale revolution stock expenses are reduced. Additionally, we applied a possible scenario to the developed simulation model and investigated strategic issues to draw desirable strategies with market changes.

디지털 경제의 확산으로 오늘날 경영환경은 개별기업간 경쟁체계에서 공급체인간의 경쟁체계로 급속도로 변화되고 있다. 이와 같은 환경변화에 대응하기 위한 도구로서 기업간의 협업체계 구현을 위한 e-파트너링의 필요성이 대두되고 있다. e-파트너링이란 가치사슬(Value Chain) 전과정에서 소수의 정예화된 파트너와 네트워크를 형성하여 새로운 사업모델을 구축하고 공동성장이 가능한 사업생태시스템(Business Ecosystem)으로 발전시켜나가는 과정이라고 정의할 수 있다. 본 연구에서는 대표적인 기간산업인 조선산업과 철강산업을 대상으로 e-파트너링 추진방안을 도출하기 위하여 e-파트너링의 수준 모형을 재정립하여 연구대상에 적합한 수준모형을 설정하고 이를 실질적으로 구현하기 위한 달성방안으로 일자별?계열별 주문 공급체계, 쌍방향 커뮤니케이션 시스템, 운송수단을 포함한 물류 인프라 개선안을 제시하였다. 제시된 달성방안을 추진한 결과, 정량적으로 납기단축 및 재고수준 감소 효과를 가져왔으며 정성적으로도 상호간의 업무커뮤니케이션이 향상되는 효과가 나타났다. With the advent of the digital economy, the business eco-system has been changing from the competition system across individual companies to that of supply chains. Under the rapidly changing business environment, it becomes true that the competitive power of the steel maker depends on the shipbuilding company, an important customer of the steel maker. Accordingly, e-partnering between a steel maker and shipbuilding companies becomes important. Schemes of developing e-partnering are presented as follows: implementation of the inter-communication system, day/sequence order and supply, improvement of infrastructure such as transport, quay etc.

정보시스템에 대한 의존도가 지속적으로 증가하는 현실에서 정보시스템에 수반되는 위험을 사전에 식별하고 평가하여 대응책을 마련하는 것은 매우 중요하다. 본 연구는 정보시스템 구축과 운영에 관한 사항을 종합적으로 점검ㆍ평가하여 고객에게 개선이 필요한 사항을 권고하는 정보시스템감리에 관한 서비스품질 결정요인을 도출하여 고객만족과의 관계를 실증하는 것이다. 정보시스템감리 서비스품질 측정항목을 도출하고 설문을 개발ㆍ조사하여 분석한 결과 첫째, 정보시스템감리의 서비스품질은 5개의 차원 즉 명성, 신뢰성, 대응성, 능력, 윤리성으로 구성되며 둘째, 서비스품질은 고객만족에 절대적으로 영향을 미치며 셋째, 고객을 만족시키면 고객 충성도가 높아진다는 사실이 실증되었다. 본 연구 결과는 감리서비스의 품질 향상을 통하여 고객을 만족시킴으로서 감리의 재계약과 추천의사를 높이려는 민간감리법인과 국가적인 정보시스템감리의 정책 방향을 설정해나가는 근거로서 활용될 수 있을 것이다. The growing impacts of information systems on our personal and professional lives would occasion us a great deal of strife and inefficiency if the systems were not well managed. Hence, the information systems audit that anticipates the risk in advance has been increasingly important. The purpose of this study is to investigate the determining factors of the service quality of the information systems audit as well as to examine its quality effects on customer satisfaction. To fulfill this objective, a survey was conducted by developing a questionnaire based on the research reports on service quality and auditing. The results show that the service quality of the information systems audit consists of five dimensions: reputation, reliability, responsiveness, competence, and ethics. Furthermore, the perceived service quality displays a significant positive association with customer satisfaction. The customer satisfaction eventually leads to a new contract or recommendation of an auditing firm.

Financial institutions have explored various business strategies to cope with the epochal turns in business environment characterized by the so-called paradigm shift, that is, the recent trend toward open market and deregulation accompanied by changing of political and economic orders. One of the most remarkable strategies in these movements is the information technology exploitation for business reformation, which exerts deterministic power on securing competitive edge in financial institutions where a relatively high level of information intensity exists. In this research we measure the levels of information infrastructure of selected domestic banks and analyze their business performance. Data for the levels of information infrastructure are collected from these nine banks in Korea, which constitute the independent variables of this research. Bank business evaluation index and values added per employee are employed as the dependent variables representing business performance of each bank. A meaningful relationship between information infrastructure and information index is also reviewed in the course of data analysis. A positive significant relationship was found between the level of information infrastructure and the business performance in matured city banks and newly-born city banks. A similar relationship was turned out to be extended to local banks after controlling several mediating factors that affect their banking business. However, a significant relationship was not found between the level of information infrastructure and the information index except for the case of matured city banks.
