Over the past several decades, several architectural approaches have been applied to develop Information Systems, The software architectural model has been recognized as one of the most important methods for improving productivity. Most conceptual models are difficult to understand and interpret at various system models. As a consequence, conceptual models of many Information Systems fail to represent, exploit, and apply to various aspects, which is needed for reducing development step of the architecture. In this paper, we will explain the architectural model as the 4＋1 View of UML. This model integrates the Knowledge Management System into five views： the Logical View, the Process View, the Deployment View, Implementation View, and the Use-Case View. Moreover, this paper will not only provide information on the application of the software architectural model by stakeholders, but also ultimately improve productivity.

The importance of international science and technology cooperation is growing more and more, but we do not know much about what criteria could be used to choose a science or a technology that needs international cooperation first and foremost among many kinds of competing sciences and technologies. Moreover, this selection process is affected by evaluators' or science/technology experts' perception, but we do not quite know what they actually see when they evaluate the needs of international cooperation. This study investigates the conditions that international science and technology cooperation is encouraged by scholars and researchers in various areas. Based on theoretical arguments of Transaction Cost Economics, Measurement View, and Knowledge-Based View, we drew hypotheses on when experts perceive greater needs of international cooperation. Using the classification categories of 10 major sciences and technologies, we collected data from 151 respondents from scientists in research institutions and colleges. As a result, we found that experts in science and technology areas perceive strong needs of international cooperation when the importance of focal science or technology is high and the relative national level of focal science or technology is low. Also, we found that the importance and relative level of focal science and technology have positive moderating effects each other. Lastly, we found that when experts evaluate their own major areas, the strength of positive relationship between the importance of science and technology and needs of international cooperation is diminished.

With the virtual asset market's rapid growth, government regulations on listing and trading procedures are expected. However, specific measures are currently lacking. To ensure stable inclusion in the institutional framework, precise regulations are needed for market development and investor protection. This study compares self-regulatory guidelines of the top domestic virtual asset exchanges with Korea Exchange's Preliminary Listing Examination Standards (2022) to enhance timeliness and relevance. It defines IEO, IPO, and ICO concepts and addresses conflicts of interest in IEO. Analyzing delisted virtual assets, it categorizes issues and classifies listing examination guidelines into formal and qualitative requirements. The study examines self-regulatory guidelines based on continuity, transparency, stability, corporate characteristics, and investor protection criteria, along with five special requirements for virtual assets. Improvement measures include regular disclosures of governance structure, circulation volume, and the establishment of independent audit institutions. This research further analyzes delisting cases, classifies issues, and proposes solutions. Considering stock market similarities, it offers measures based on the institutional framework.

As knowledge management is recognized as a core value of organizations, organizations are increasing their investment in policies and technologies for knowledge management. However, since SMEs have relatively few resources to support knowledge sharing, which is the core of knowledge management, there is a possibility that continuous knowledge management will be difficult. This study suggests the negative motivation(job burnout) on the knowledge hoarding of SME employees and the conditions to be improved at the organizational level (shared goal, knowledge sharing culture, and person-organization fit). In this study, a hypothesis was presented through a study related to transaction theory to explain the stress in the relationship between the organization and the individual. This study collected samples through a questionnaire targeting workers of SMEs with knowledge management policies. In addition, the hypothesis was verified by performing structural equation modeling. As a result of the study, shared goal and knowledge sharing culture reduced knowledge hoarding through mitigating job burnout. In particular, person-organization fit moderated the relationship between shared goal, knowledge sharing culture, and job burnout. The study presents academic and practical implications in terms of suggesting factors to mitigate the knowledge hoarding of employees for continuous knowledge management of SMEs.

Given the prevalence of home trading systems, it has become important to examine user behaviors in a stock investment environment. In this vein, this paper developed an integrated model to deeply understand the key determinants of user's continuance intention to use investment information through constructs prescribed by incorporating trust and perceived risk into expectation-confirmation model. The proposed research model was tested by using survey data collected from 160 users who have experience with stock investment. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that the proposed framework provides a statistically significant explanation of the variation in continuance intention to search investment information. The findings revealed that trust and perceived risk are more prevalent predictors of continuance intention to use investment information compared to perceived usefulness. It was also found that user satisfaction serves as the salient antecedents of continuance intention to use investment information. The theoretical and practical implications of the findings were described.

Configuration은 도메인 지식을 이용해서 주어진 모든 요구를 충족시키는 컴포넌트를 갖는 시스템을 구성하기 위한 기술이다. 최근 전자 상거래는 역경매, 공동구매, 사용자 프로파일에 의한 제품의 추천 등 다양한 방식으로 구매자 중심의 사거래 행위를 하고 있다. 하지만 아직도 전문 지식이 필요한 제품의 구입시에 구매자는 많은 어려움을 겪고 있다. 이러한 구매자의 행위를 보조하기 위한 수단으로써 전문가 시스템에서 수년간 연구되어 온 Configuration 기술을 확장 도입하였다. 본 논문에서는 도메인에 대한 규칙(Rules)에 기반해서 Classification Problem Solving 방법과 Constructive Problem Solving 방법을 적용하였다. 구매자와의 능동적인 질의 수행을 하여 제품에 대한 요구를 정확히 한 뒤, 얻어진 사실(Facts)을 Classification Problem solving에 이용이 되어 제품 모델이 결정된다. 이 제품 모델은 구매자를 위해 특성화 되어 있기 않기 때문에, Constructive Problem Solving을 이용한다. 이런 내용을 기반으로 컴퓨터 조립을 위한 Configurator를 디자인하고 구현했다.

지식기반경제에서는 기식을 창출하거나 활용하는 능력이 기업의 경쟁력을 결정하는 중요한 요소가 될 뿐만 아니라 국가적 경쟁우위의 기본이 된다. 산업경제에서 지식기반경제로의 이행이 가속화됨에 따라 부동 산 및 설비 등 유형자산 보다는 노하우, 특허권 등의 무형자산이 기업 경쟁력에 미치는 영향이 더욱 커지고 있다. 유형자산과 마찬가지로 기업이 소유하고 있는 무형자산인 특허권의 합리적 가치평가도 중요하다. 왜냐하면 특허 가치의 정확한 평가는 기술 거래 시장의 활성화를 가져올 수 있고 또한 기업의 특허전략 수립에 필수적이기 때문이다. 하지만 유형자산과는 달리 무형자사인 특허권의 정확한 가치평가는 매우 어려운 것으로 알려져 있다. 본 연구의 목적은 특허가치 평가에 영향을 미치는 요소들을 살펴보고자 함에 있으며, 그 중에서도 제품 특성에 초점을 맞추었다.

주식 시장을 예측하는 문제는 금융 분야에서 중요한 관심이 되어왔다. 주식 시세는 시장 환경의 변화에 따라 급격한 변화를 갖는다. 따라서 주식 투자로부터 이윤을 창출하기 위해서 주식을 사고 파는 시점을 결정하는 문제는 중요하다. 본 연구에서는 주시 매매 타이밍을 예측하기 위해서 캔들스틱 차트(Candlesticks chart)분석을 이용한 전문가 시스템(Expert System)으로서 '차트 해석기 (Chart Interpreter)'를 설계, 개발하였다. 주식 가격의 변동을 예고하는 패턴들을 정의하고 그 패턴들의 의미에 따라 매미결정을 첨가한 규칙을 생성하였다. 정의된 패턴들은 의미에 따라 크게 하락형, 상승형, 중립형, 추세지속형, 추세 전환형으로 분류된다. 정의된 패턴과 지식베이스의 유용성을 검증하기 위해서 수행된 1992년부터 1997년에 걸친 과거 한국 주식 시장 실거래 투자 데이터에 대한 실험결과는 평균 투자 성공률이 약 72%로서 주식시장에서 투자자들의 투자를 돕는데 우수한 지표로서 사용될 수 있음을 보였다. 또한, 개발된 지식베이스는 특정 연도나 특정 분야에 따라 예측력이 크게 변하지 않은 시간 독립적이고 분야 독립적인 특성을 가짐으로 분야나 시간에 구애받지 않고 사용할 수 있다는 장점을 갖는다.
