The small and medium sized enterprises (hereinafter SMEs) are already at a competitive disadvantaged when compared to large companies with more abundant resources. Manufacturing SMEs not only need a lot of information needed for new product development for sustainable growth and survival, but also seek networking to overcome the limitations of resources, but they are faced with limitations due to their size limitations. In a new era in which connectivity increases the complexity and uncertainty of the business environment, SMEs are increasingly urged to find information and solve networking problems. In order to solve these problems, the government funded research institutes plays an important role and duty to solve the information asymmetry problem of SMEs. The purpose of this study is to identify the differentiating characteristics of SMEs that utilize the public information support infrastructure provided by SMEs to enhance the innovation capacity of SMEs, and how they contribute to corporate performance. We argue that we need an infrastructure for providing information support to SMEs as part of this effort to strengthen of the role of government funded institutions; in this study, we specifically identify the target of such a policy and furthermore empirically demonstrate the effects of such policy-based efforts. Our goal is to help establish the strategies for building the information supporting infrastructure. To achieve this purpose, we first classified the characteristics of SMEs that have been found to utilize the information supporting infrastructure provided by government funded institutions. This allows us to verify whether selection bias appears in the analyzed group, which helps us clarify the interpretative limits of our study results. Next, we performed mediator and moderator effect analysis for multiple variables to analyze the process through which the use of information supporting infrastructure led to an improvement in external networking capabilities and resulted in enhancing product competitiveness. This analysis helps identify the key factors we should focus on when offering indirect support to SMEs through the information supporting infrastructure, which in turn helps us more efficiently manage research related to SME supporting policies implemented by government funded institutions. The results of this study showed the following. First, SMEs that used the information supporting infrastructure were found to have a significant difference in size in comparison to domestic R&D SMEs, but on the other hand, there was no significant difference in the cluster analysis that considered various variables. Based on these findings, we confirmed that SMEs that use the information supporting infrastructure are superior in size, and had a relatively higher distribution of companies that transact to a greater degree with large companies, when compared to the SMEs composing the general group of SMEs. Also, we found that companies that already receive support from the information infrastructure have a high concentration of companies that need collaboration with government funded institution. Secondly, among the SMEs that use the information supporting infrastructure, we found that increasing external networking capabilities contributed to enhancing product competitiveness, and while this was no the effect of direct assistance, we also found that indirect contributions were made by increasing the open marketing capabilities: in other words, this was the result of an indirect-only mediator effect. Also, the number of times the company received additional support in this process through mentoring related to information utilization was found to have a mediated moderator effect on improving external networking capabilities and in turn strengthening product competitiveness. The results of this study provide several insights that will help establish policies. KISTI's information support infrastructure may lead to the conclusion that marketing is already well underway, but it intentionally supports groups that enable to achieve good performance. As a result, the government should provide clear priorities whether to support the companies in the underdevelopment or to aid better performance. Through our research, we have identified how public information infrastructure contributes to product competitiveness. Here, we can draw some policy implications. First, the public information support infrastructure should have the capability to enhance the ability to interact with or to find the expert that provides required information. Second, if the utilization of public information support (online) infrastructure is effective, it is not necessary to continuously provide informational mentoring, which is a parallel offline support. Rather, offline support such as mentoring should be used as an appropriate device for abnormal symptom monitoring. Third, it is required that SMEs should improve their ability to utilize, because the effect of enhancing networking capacity through public information support infrastructure and enhancing product competitiveness through such infrastructure appears in most types of companies rather than in specific SMEs.

The purpose of this study is to provide a practical guide for establishing BSC that can be practically applied by SMEs. To this end, a case study was conducted to establish a performance evaluation system through a field-required Balanced Scorecard (BSC) for company J, a tent pole manufacturer, and to provide a management strategy system map. As a survey method, the requirements of the ordering organization were organized through a comparison of the BSC-related proposal requests in the first stage. The BSC establishment method was organized through the arrangement of the second stage result report. The 3rd stage BSC derived KPI indicators for SMEs for each of the 4 perspectives. A corporate vision was derived through a 4-step SWOT analysis. A strategy map was developed through 5-step field-required KPI, weight setting, and BSC. The 6-step final strategy system was also drawn up. As a result of the study, the four perspectives of the BSC were reconstructed by department. That is, the financial (financial) perspective is from the executives' perspective, the customer's perspective is from the sales department's perspective, the internal process perspective is from the design department/production quality department's perspective, and the learning/innovation perspective is from the management department's perspective. In addition, a total of 11 CSFs and a total of 49 KPIs of J company were derived. The limitation of the study is that the final strategy system through the company's BSC has only been carried out, and it needs to be linked with the company's compensation system in the future.

The technical regulation and conformity assessment procedure of our country on ICT equipments is currently required to have more innovation due to the request of main trade countries, the second phase conclusion of MRA, necessity of expansion of conformity assessment service market and demand of manufacturers. The world's leading advanced countries have already proceeded with innovation based on privatization plan. According to the comparative analysis of the level, it turned out that Japan obtained the highest level of privatization while South Korea ranked the lowest level. According to the research result of examination and certification ability of private institutions of our country, it turned out that our country is expected to have possibility of achieving higher level of privatization than that of the present. Moreover, according to the questionnaire survey conducted to the persons concerned regarding privatization direction, they gave positive response to all the indicated survey contents of privatization direction in terms of "delegation of certification services to private sectors (contracting-out)", "transformation of EMC into private voluntary standard" and "changeover of conformity assessment agent". However, from the view of acceptance and conflict model, it is estimated that starting from "delegation of certification services to private sectors (contracting-out)" seems to be the most advisable plan. Also, prior to privatization, it is required to improve relevant systems such as certification examiner system.

Recently, the demand of labels for product management is increasing, as the automation system becomes more common. the development of functional labels which can be used in various environments has been rapidly proceeded. In the case of a printed circuit board, barcode labels with thermal and chemical stability are generally used due to a high temperature process around $300^{\circ}C$ and chemical cleaning in the manufacturing process. However, the yellowing phenomenon of labels that can lower the resolution of printed barcode image still needs to be prevented. In this study, we prepared a composite coating layer using a silica inorganic binder and a titanium dioxide white pigment, and developed a functional labels with thermal and chemical stability. The silica inorganic binder prepared by sol-gel process was confirmed to show excellent adhesion and abrasion resistance with the polyimide film. The white coating layer could be formed on the polyimide film with mixing the silica inorganic binder and titanium dioxide white pigment. The prepared coating layer showed excellent whiteness and glossiness above $400^{\circ}C$. The excellent chemical stability of the coating layer was also confirmed by the chemical treatment with acidic (pH 1.6) and basic (pH 13.6) cleaners.

The productionof the highly relible softwae systems and theirs performance evaluation hae become important interests in the software industry. The software evaluation has been mainly carried out in ternns of both reliability and performance of software system. Software reliability is the probability that no software error occurs for a fixed time interval during software testing phase. These theoretical software reliability models are sometimes unsuitable for the practical testing phase in which a software error at a certain testing stage occurs by causes of the imperfect debugging, abnornal software correction, and so on. Such a certatin software testing stage needs to be considered as an outlying stage. And we can assume that the software reliability does not improve by means of muisance factor in this outlying testing stage. In this paper, we discuss Bavesian software reliability growth modeling and estimation procedure in the presence of an imidentitied outlying software testing stage by the modification of Jehnski Moranda. Also we derive the Bayes estimaters of the software reliability panmeters by the assumption of prior information under the squared error los function. In addition, we evaluate the proposed software reliability growth model with an unidentified outlying stage in an exchangeable model according to the values of nuisance paramether using the accuracy, bias, trend, noise metries as the quantilative evaluation criteria through the compater simulation.

티타늄 화합물은 뛰어난 물리적 특성과 인체 무해성을 가지고 있어 생체, 내식 및 내마모 재료 등에 널리 응용되고 있으며, 다양한 색상 구현을 통한 미려한 외관 등 기능성을 위한 표면처리 분야에도 많은 관심을 받고 있다. 이중 질화 티타늄은 금색을 대체할 수 있는 물질로 코팅방법과 기판온도, 바이어스, 질소유량 등과 같은 공정변수 제어를 통해 그 물성을 변화시킬 수 있어 기능적 측면과 함께 미려한 외관처리에 응용이 가능하다. 본 연구에서는 아크(cathodic arc) 코팅 시스템을 이용하여 다양한 조건에서 TiN 박막을 제조하고 그 특성을 평가하였다. 아크 장비는 화합물 박막을 코팅할 수 있는 아크 소스와 시편 홀더, 가스 주입구, 시편 가열장치 그리고 배기 장치로 구성되어 있고, 아크 소스에 장착된 타겟은 99.5%의 Ti 타겟을 사용하였다. 시편과 타겟 간의 거리는 약 31cm이며, 시편은 알코올과 아세톤으로 초음파 세척 된 강판(냉연 강판), 실리콘 웨이퍼를 사용하였다. 시편을 진공용기에 장착하고 ${\sim}10^{-6}$ Torr까지 진공배기를 실시하고, Ar 가스를 진공용기 내로 공급하여 ${\sim}10^{-4}$ Torr에서 시편에 bias (Pulse : 400V)를 인가한 후 아크를 발생시켜 약 5분간 청정을 실시하였다. 플라즈마 청정이 끝나면 시편에 인가된 bias를 차단하고, 질소 유량, 온도, bias, 시간 등의 공정변수에 따라 코팅을 실시하였다. 질소의 유량이 80sccm 일 때, Ti 금속 결정구조가 나타났는데, 이는 질소와 충분하게 반응하지 못한 Ti이 기판에 코팅되어 나타나는 현상으로 판단된다. 색상변화에서는 질소 유량이 증가함에 따라 노란색이 짙어지며, TiN은 시편에 인가되는 bias 전압이 높아질수록 붉은색이 증가하고, 온도에 따른 큰 변화는 관찰되지 않았다. 공정변수에 따른 반사율 변화는 TiN의 경우 질소 가스 유량이 200sccm, bias 150V, 공정 온도 200도에서 반사율이 가장 높았으며, 코팅 시간이 짧을수록 반사율이 높아지는 경향을 나타냈다. 따라서 본 연구에서 얻어진 결과를 외관 코팅 분야에 응용한다면 장식성과 외관의 경도, 내마모성, 내식성의 향상 등 많은 장점을 가질 것으로 예상된다.

As todays's networks are typically heterogeneous and very often comprised of multi-platform, multi-vendor network components, mobile agents have been proposed as a solution to the problem of the management of increasingly heterogeneous networks. Mobile agents are no longer statically resident on managed devices for network management: in contrast, they are migratory, replaceable at any time as necessary, and may be equipped with mini expert systems which can diagnose and fix networks' faults on behalf of the manager. Therefore, in this paper, the MIB browsing facilities for network management using the JAMAS and mobile agents are implemented. That is, the network manager accesses the MIB information through mobile agents with which communicate the SNMP agent of each of managed devices. The implementation performance is also evaluated.

The enhancement of the cold-start capability of polymer electrolyte fuel cells is of great importance in terms of the durability and reliability of fuel-cell vehicles. In this study, vanadium oxide films deposited onto the flat surface of metallic bipolar plates were synthesized to investigate the feasibility of their use as an efficient self-heating source to expedite the temperature rise during startup at subzero temperatures. Samples were prepared through the dip-coating technique using the hydrolytic sol-gel route, and the chemical compositions and microstructures of the films were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, and field-emission scanning electron microscopy. In addition, the electrical resistance hysteresis loop of the films was measured over a temperature range from -20 to $80^{\circ}C$ using a four-terminal technique. Experimentally, it was found that the thermal energy (Joule heating) resulting from self-heating of the films was sufficient to provide the substantial amount of energy required for thawing at subzero temperatures.

20세기 말까지만 해도 경제발전은 자원고갈과 자연환경파괴를 통한 대량생산 및 대량소비를 전제로 하여 이루어 졌다고 평가할 수 있다. 그 결과 세계의 자연환경은 급속히 훼손되었으며, 환경오염은 이제 인류의 생존을 위협하는 단계에 이르렀다. 이 같은 위기상황에 대처하기 위하여 지난 1980년대부터 선진국을 중심으로 환경경영에 대한 인식이 확산되기 시작하였다. 무엇보다도 자연환경 의 보존을 요구하는 사회적 압력은 기업으로 하여금 환경경영 의 필요성을 깨닫게 하였다. 환경 경영이란 기업들이 새로운 비교 우위를 창출하기 위하여 경 영 방식의 혁신에 있어서 자연환경을 초점으로 삼는 것이다. 환경경영이란 환경보전을 요구하는 이해 관계자들로부터의 요구에 기업이 이에 적극적으로 대응함으로써 한경보호와 경영성과를 동시에 달성하는 종합적인 경영을 의미한다. 환경경영은 이업의 전 활동에 걸친 전사적인 전략적 차원의 활동으로 기업경영이 어느 한 기능분야에 국한된 개념이 아니다. 궁극적으로 환경보호와 성장의 조화라는 기업의 목표달성을 위해 기업의 생산, 재무, 인사조직, 마케팅, 회계정보시스템등의 활동이 모두 통합되어야 할 것이다. (김종대, 이의훈:2003) 최근 들어 환경경영이 기업의 가치에 미치는 영향에 대한 연구가 활발히 전개되고 있는 가운데 선진국의 경우 기업의 가치가 대체적으로 정확하게 주가에 반영되고 있는 가운데 선진국의 경우 기업의 가치가 대체적으로 정확하게 주가에 반영되고 있어 우리기업들이게 시사하는 바가 크다 하겠다. 환경경영과 기업가치와의 상관관계를 조사한 연구결과에 따르면 우수한 환경경영을 실천하고 있는 기업의 주식을 중심으로 포트폴리오를 구성한 펀드의 수익율이 상대적으로 높게 나타나고 있어 환경경영의 중요성을 뒷받침하고 있다. 이를 위하여 본 논문은 우선적으로 기업의 환경경영에 기본이 되는 중요한 환경경제 유인정 책과 규제들을 중심으로 살펴보고자 하였다.학적 합성이 아주 까다로운 약제물질 등을 천연상태에서 합성하고 있기 때문이다. 또 식물은 lipoxygenase 효소계가 있어서 마치 천연물 석유제조공장과 같은 제조공정 capacity를 가지고 있다. 그러면 식물/식품 GMO는 안전한 것인가? 아니, KBS의 한 사회자가 말했듯이, 그리고 많은 소비자들이 믿는 것처럼 GMO는 위험한가? GMO에 대한 일반 사람들의 공포감은 Green Peace 당원들뿐만 아니라 일부 과학자들에 의해서도 조장되고 있다. 이러한 분위기 속에서 GMO에 의한 제2 녹색혁명은 Africa 대륙에서의 제1 녹색혁명이 지금도 지연되는 것과 같다고도 볼 수 있다. GMO의 환경에 대한 악영향은 과대 선전되어있는 것이 아닌가? 마치 GMO가 화학비료, 농약제보다 더 위험하다고 믿는 사람들도 많다. 나는 이러한 GMO 공포증이 과학적으로 그리고 "Risk Assessment"의 견지에서 볼 때 그 근거가 희박하다고 보여주는 몇 몇 실험 및 경험 사실들을 인용하려 한다. 그리고 올바른 Risk Assessment야 말로 한국의 21세기 BT 산업을 경쟁력 있게 하고 국민 년 소득 2만불 달성에 중요한 기여를 하게 될 것이라고 생각한다. 한국은 농토가 적고 천연자원이 빈약하다. GMO는 21세기의 생존 경쟁 산업이다. 제2의 녹색혁명은 얼마든지 가능하며, 한국은 부족한 농토와 빈약한 자원에도 불구하고 능력 있는 인적자원이 풍부하여 GMO 개발 연구에 국제적 경쟁력을 키울 수 있다. 그러나 GMO에 대한 논쟁만 하고 있으면 이미 때가 늦는다. 미국은 이미 GMO-BT 시장을 거의 완전 독점했으며, 타국에서의 논쟁과 불합리적으로 엄격한 GMO 관련 규정을 조장하고 환영한다.이상의 결과와 같이 인삼 saponin 성분들은 arachidonic acid로부터 cyclooxygenase를 통해 일단 생성된 endoperoxide에서 각각의 prostagland
