우리가 살아가는 21 세기는 산업화시대와는 달리 급격한 경영환경의 변화 기술융합을 통한 끊임없는 신기술의 등장, 가치사슬의 변화, 프로세스(process)의 통합과 자동화로 인한 가격 등이 파괴되면서 생존을 위한 치열한 경쟁의 시대로 접어들고 있다. 이러한 사회환경의 변화에 따라 지식의 창출 못지 않게 지석의 보호도 중요하게 되었다. 그러나 공공기관의 지식은 체계적인 관리 체계가 이루어지지 않아 담당자의 인사.이동 혹은 퇴직 등으로 인하여 축적된 업무지식이 개인과 함께 그 조직에서 사라져 지식경쟁력이 약화되는 현상을 초래하고 있다. 따라서 본 연구에서는 기존의 단위업무시스템을 통합하여 새롭게 구축된 지식관리시스템을 조기에 정착시키고 이를 활용하여 무형자산의 가치를 극대화하기 위한 방안으로 $2002.12.01{\sim}2003.05.31$ 까지 6 개월 동안 지식관리시스템에 등록된 지식을 분석하여 지식경영을 활성화할 수 있는 방안과 미래사회의 핵심이 될 지석근로자를 양성할 수 있는 방안으로 자신의 능력을 극대화할 수 있는 3 가지 원리와 5 차원 전면교육학습법에 대하여 제시하였다.

The phase in digital technology expedited low-budget digital film productions in the Korean film industry; hence the international film festivals circuit became the launching pad for Korean directors as they built their reputation and careers around the critical acclaim. Pieta (Kim Ki-Duk)'s Claim on Golden Lion prize at the Venice Film Festival in 2012 would be one of the splendid achievements - the festival is considered to be one of the top the international film festival. However, the increased volume of the low-budget digital film productions are not necessarily proportional to the growth in the quality of the productions. The drawbacks to the production system appeared to be the underlying cause. In attempt to approach the issue, this article explores the production system from 2000 until now. It is illustrated that the value chain model has been transformed from general ones into vertical & horizontal integrated ones. A notable example of successful indie bands-around Hongik university area-, as well the analysis on the low-budget hit productions, especially from the mid-2000's, are introduced as the case studies. The strategies that led the success, such as subsidies policy, the tax benefits on investment firms and production companies, and the aid in international film festival submissions on low-budget digital film productions, are thus examined with further suggestions.

A value net is a business design that uses digital supply chain concepts to achieve both superior customer satisfaction and company profitability. In order to implement the value net model, information processing and distribution needs to occur in real time. Software agent technology is becoming popular due to the inherent characteristics of autonomy, distributedness and modularity. In this paper, we adopt agent technology to handle all real time decision process, making the value net model a complex multi-agent network of decision makers. For the agents to properly coordinate their respective activities we develop MAVN model, a Web-based multi-agent language grounded in the XML and Java.

Today's individual firms no longer compete as solely autonomous entities, but rather as supply chain. As such the competitive position of a port is not only determined by its internal strengths but also it is also affected by its links in a global supply chin. In other words, port competitiveness is becoming increasingly dependent on external coordination and control of the whole supply chain. The main purpose of this paper is to examine how a port embeds itself into supply chain in order to strengthen its competitive position by focusing on Dubai port case. This paper found that Dubai port used three phases-insertion, integration and dominance-as a strategies for how it can embedded into global supply chain successfully. Dubai's global supply chain strategies give some implications for the further development of the Port of Gwangyang. First, the Port of Gwangyang should fully utilize symbiotic relationship with Gwangyang free Economic Zone. Second, the integration between Korea Container Terminal Authority and GYFEZ can be recommended for fast decision-making and providing a one-stop-service. Finally, Gwangyang should pursue an aggressive supply chain strategy, aims at dominance in the regional port network through port alliance with small and medium ports in neighboring area.

전통적인 비용수익 분석법 (CBA approach) 과 활동기준원가계산 방법 (ABC approach)과 같은 지금까지의 방법으로는 전략적 정보시스템이나 정보 하부구조를 효과적으로 평가하고 정당화하는데 한계가 있다고 지적되어왔다. 따라서, 본 논문은 정보시스템의 하부구조를 이루고 있는 데이터 웨어하우징을 스물여섯 개의 데이터 웨어하우징 성공사례 분석을 통해서 데이터 웨어하우징이 가치사슬 모델의 각 활동에 어떻게 활용되고 있는지를 분석하고, 경쟁우위적 관점에서 이들 사례들의 공통점을 찾아내어, 데이터 웨어하우징을 경쟁우위적 관점에서 보다 효과적으로 정당화할 수 있는 모델을 제시하고 있다. 이 모델은 기존의 정보시스템 정당화에 사용되어왔던 방법들의 단점을 보완하여, 기업들이 데이터 웨어하우징이나 경쟁우위를 확보하기 위해서 구축하는 다른 정보시스템들을 경쟁우위적 관점에서 정당화하고자 할 때 유용한 도구로써, 기존의 방법들과 병행해서 사용하면 보다 효과적으로 정보시스템들을 평가하고 정당화할 수 있으리라 생각된다.

Supply chain management is a strategic thinking which enhances the value of supply chain and adapts more promptly for the changing environment. For the seamless partnership and value creation in supply chains, information and knowledge sharing and proper partner selection criteria must be applied. Thus, the partner selection criteria are critical to maintain product quality and reliability. Each part of a product is supplied by an appropriate supply partner. The criteria for selecting partners are technological capability, quality, price, consistency, etc. In reality, the criteria for partner selection may change according to the characteristics of the components. When the part is a core component, quality factor is the top priority compared to the price. For a standardized component, lower price has a higher priority. Sometimes, unexpected case occurs such as emergency order in which the preference may shift on the top. Thus, SCM partner selection criteria must be determined dynamically according to the characteristics of part and its context. The purpose of this research is to develop an OWL model for the supply chain partnership depending on its context and characteristics of the parts. The uncertainty of variable is tackled through fuzzy logic. The parts with preference of numerical value and context are represented using OWL. Part preference is converted into fuzzy membership function using fuzzy logic. For the ontology reasoning, SWRL (Semantic Web Rule Language) is applied. For the implementation of proposed model, starter motor of an automobile is adopted. After the fuzzy ontology is constructed, the process of selecting preference-based supply partner for each part is presented.

전자상거래의 활성화를 위한 전자지불시스템은 보안성과 통용성의 양면을 만족해야한다. 현재 서비스중인 전자현금이나 전자화폐는 디지털정보가 직접 화폐가치를 지니고 있기 때문에 인터넷에서 분실시 복구가 불가능하다. 또한 전자수표나 가상은행을 이용한 계좌이체방식은 인터넷 통용성이 약하며, 신용카드를 이용한 전자지불시스템은 통용성은 양호하나 신용카드번호 노출의 위험이 있고 수수료 등 트랜잭션 비용이 소요되므로 소액지불에는 불리하다. 전자지불시스템의 활성화를 위해서는 신용카드와 같이 휴대 가능하고 실세계에서의 통용성이 우수한 시스템이어야 하며, 직접 지불이 가능하고 소액지불도 가능한 체계이어야 한다. 본 논문에서는 제안하는 새로운 지불시스템 "스마트-Pay"는 모든 사람들이 은행을 사용하고 있다는 점을 착안하여 은행계좌기반이면서 실세계 및 인터넷에서 직접지불이 가능하도록 설계한 것이다. 본 지불시스템의 안전도는 발행기관, 은행, 고객으로 이어지는 인증사슬에 의한 강력한 인증과 스마트카드에 의한 전자서명에 의존하며 기밀성, 무결성, 부인봉쇄를 제공하므로 안전하다고 평가된다.

This study has analyzed whether the virtuous cycle of value-added between the processes within the company has formed and whether the virtuous ecosystem between the processes within the industry has been built through the analysis of value chain(VC) and value system(VS) targeting the Korean photovoltaic companies. For a study method, after conducting a survey on the companies, a regression analysis was performed on the causal relationship between the process within the VC and VS. Based on the results of the analysis, for the VC of the Korean photovoltaic industry, an increase in the R&D support from the government has led to the increase in the investment of R&D for the related industry, and the increase in the investment of R&D has contributed to the increase in the growth of its productivity, and the growth in the productivity of R&D has influenced the increase in the production of solar products. In addition, the reduction of photovoltaic production cost for the company has influenced the increase of recurring profit margin compared to the sales. However it was shown that the increase in the company's production volume does not contribute to the reduction of production cost. Meanwhile, the increase in recurring profit margin compared to the sales were influencing the increase in the production volume but it was shown that the increase in the company's investment of R&D was not a contributing factor thus it was not included in the virtuous cycle. It was analyzed that the VS was shown not to influence all other processes within the industry except for the module companies where the increase in the recurring profit margin compared to the sales was influenced by the increase in the recurring profit margin compared to the sales of solar cell companies. This shows that the virtuous industrial ecosystem which should be made under the mutual cooperation by the ingot, wafer, solar cell, module and system companies are yet incomplete.
