중앙정부 및 지방정부들은 지역마다 지리적 환경적 경제적 기반을 고려한 유비쿼터스 테마를 가지고 U-City를 추진하고 있다. 그러나 현재 지방정부들이 추진하고 있는 U-City 건설 계획은 시민에게 제공되어야 할 서비스와 공급자인 도시정부에서 제공해야 할 유비쿼터스 행정 서비스가 무엇인가에 대한 담론의 과정이 미흡한 상황에서 공급자 위주의 방식으로 서비스를 제공할 계획에 있다. 위와 같은 문제 의식 하에 본 연구는 충주시 공무원을 대상으로 공공부문에 U-공공서비스의 도입의 필요성과 서비스의 유형, 그리고 제공해야할 서비스의 우선순위가 무엇인지를 실증적으로 분석하고 그 개선방향을 제시하였다. 분석결과 공공부문 영역에 필요한 서비스 유형 및 우선순위는 일반행정부문, 의료 복지부문, 안전 방재부문, 교통 물류부문, 문화 관광부문과 교육부문의 순서로 분석되었다.

In this paper, we implemented technology assessment on the public R＆D activities in IT field in order to select the promising technologies, so called "star technology," making for national industry development. Technology assessment frame in this study included qualitative factors. IT technologies are classified five sector - network, wireless/broadcasting, SW/application/computer/terminal equipment, semiconductor/component. Expert opinion interviews on each field are carried out. Assessment factors consist of technology usefulness and technology competitiveness. In the final analysis, 23 technology items selected as a promising technologies and the results can be used public R＆D planning and If industry policy.

Nowadays almost nations try to promote the competition of nation through the development of national science technology. Also Korea has been engaging in this race of through public research & development institute. But recently the commercialization of R&D products appears a poor result in the royalty of technology according weak technology transfer toward IT small and medium-sized enterprises. Even If we have been trying to find the problems and causes, as yet it is true that we don't solve clearly the problem, make a diagnosis about it. This paper analyzes the process of commercialization in public R&D research institute(ETRI: Electronics and Telecommunications Research Institute) through system thinking and researches an interrelationship among government agency, public R&D research institute, and enterprise. This one can find the fact that between research fund and R&D products, transfer technology and royalty, and enterprise's operating profit and active technology transfer like adding technology development is a positive feedback loop. This positive feedback loop in the commercialization of public R&D research institute carries out very important role in examining problems in R&D product's commercialization. Also this paper looks forward to being a guide in the commercialization of public R&D research institute.

All over the world, the attention on the exploitation of public research, which is mainly implemented by technology transfer, has increased in recent years. Licensing, which is one of representative mechanisms for public-to-private technology transfer, is accompanied by the frequent conflicts in negotiating a license payment between public research institutes (PRIs) and private firms. In spite of the body of literature on technology transfer in a licensing context, it focuses on contracts between private firms. Even the existing literature, which addresses public-to-private technology transfer through licensing, to our knowledge, has not yet formalized an established licensing model. This paper develops a mathematical model of public-to-private licensing, not hitherto tried by academics. The model addresses important issues to be applied comprehensively in licensing practice, such as determining a royalty rate, balancing between an initial payment and a running royalty, designing an inventor's incentive system, and setting a minimum payment as a screening criterion. The paper also provides reasonable management implications to controversial issues in technology transfer from PRIs to private firms, partly employing the comparative analysis between current stylized licensing practice and the one suggested in the model. We hope that study contributes to providing the foundation on which the theory on public-to-private licensing would extend to an in-depth level.

The main objective of this article is to highlight the progress made in the development of new materials that have been gradually used by humans until today. Of course, this progress must be associated with other parameters in order to guarantee sustainable development. For this, today, it has become urgent to reduce the consumption of cement by resorting to its partial or total replacement by other similar materials in order to reduce CO₂ emissions in our environment. This should certainly help to develop greener building materials. In this study, it was decided to proceed with the partial or total replacement of Portland cement type CEM II/B-L-42.5N by slate and lime that had not undergone any previous transformation. The results obtained revealed that the mortar whose substitution compared to the replacement of cement (100%) cement and sand (0/4) confers better kinetics than those of the series composed of(100%) cement and fraction rubble (0/1).

과학기술 수용자는 과학기술 변화과정을 결정하는 중요한 이해관계자이다. 하지만 이들이 과학기술이슈에 대해 어떤 생각을 가지고 있는지 확인하는 기존의 방법들은 많은 노력과 시간이 필요한 것으로 알려져 왔다. 본 연구에서는 빅데이터 분석에 널리 사용되는 토픽모델링을 활용해 온라인 토론장에 게시된 글을 분석하여 한국인의 원자력발전에 대한 인식을 알아보고자 한다. 이것은 거시이슈들이 일반 과학기술 수용자 인식구조에 어떤 영향을 미치며, 변화된 인식구조의 지속성을 이해하는데 도움을 줄 수 있다. 빅데이터를 이용해 실시간으로 특정 과학기술이슈에 대한 일반인의 인식을 파악한다면, 과학기술 수용자(일반인)와 공급자(전문가) 집단 사이의 인식간극을 줄이는데 도움을 줄 수 있을 것으로 기대한다.

Metformin is an oral anti-hyperglycemic agent, which is the most commonly prescribed medication in the treatment of type-2 diabetes mellitus. It is purportedly associated with a reduced risk for various cancers, mainly exerting anti-proliferation effects on various human cancer cell types, such as pancreas, prostate, breast, stomach and liver. This mini-review highlights the risk and benefit of metformin used for cholangiocarcinoma (CCA) prevention and therapy. The results indicated metformin might be a quite promising strategy CCA prevention and treatment, one mechanism being inhibition of CCA tumor growth by cell cycle arrest in both in vitro and in vivo. The AMPK/mTORC1 pathway in intrahepatic CCA cells is targeted by metformin. Furthermore, metformin inhibited CCA tumor growth via the regulation of Drosha-mediated expression of multiple carcinogenic miRNAs. The use of metformin seems to be safe in patients with cirrhosis, and provides a survival benefit. Once hepatic malignancies are already established, metformin does not offer any therapeutic potential. Clinical trials and epidemiological studies of the benefit of metformin use for CCA should be conducted. To date, whether metformin as a prospective chemotherapeutic for CCA is still questionable and waits further atttention.

Technology transfer from public research institutes is receiving an ever increasing importance in today's fast growing economy. Many factors have been cited as influencing the transfer performance. This study is focused on the strategy of institutes which is characterized by technology strategic factors and organizational/institutional factors. Methodologically, the technology strategy is represented by the information contained in applied patents, and the performance of technology transfer is indicated by the number of licensing contracts and royalty income. To further improve the contribution of public research institutes through technology transfer, I argue that individual institutes become more specialized in specific field and become more open to collaboration. It is also recommended that public research institutes gather together since it is easy to form the consortium of technology licensing office and it is not necessary to be located near the industrial field.

As the amount of IT investment and the complexity of information systems in public agencies have been increased, efficient and structured management of IT systems is more emphasized. For the Korean government. ITA (Information Technology Architecture) is one of the core parts of the e-Government initiative. Also introducing and managing ITA in organizations is mandated by law in Korea. The objective of the paper is to study whether using ITA in public agencies is related with their IT capability and IT performance or not. A questionnaire had been designed for the purpose, and a survey had been performed on Korean public agencies. The survey results show that using ITA has influence on relation and technology capability. However, ITA does not influence on human capability and IT performance. The reason why using ITA is linked to relation and technology capability is that ITA includes relationship between both business and technology. Also ITA provides a technical reference model (TRM) and standard profile (SP), so it has influence on technology capability.
