Business Process Management (BPM) is an emerging trend of managing business process life cycles and integrating heterogeneous systems . Recently, BPM is considered as an essential element for automation of complex business processes involving many companies, particularly for those in an e-Business environment. In such an environment, it is very important for each business partner to trace history of resources. However, it has been a difficult problem for Workflow Management Systems(WFMSs) to support management of resource changes because of limited storage, complex process structure, and absence of formal change model. In this paper. a new framework is proposed, which can support change management for documents, one of core resources of business process. Under a traditional WFMSs framework, all workflow components belong to either build-time or run-time function, and executions of workflow processes are performed by the two functions . To manage changes of documents while process executing. a new framework with additional component modules are required. A version control method is introduced for the purpose of managing document changes. The proposed method includes five models for document structure, process structure, association between process and document, version management, and efficient version storage. A prototype system is developed to demonstrate the effectiveness of the proposed models.

최근 전자 상거래 시장이 급격한 성장을 이루면서 고객들의 급변하는 니즈를 파악하는 것이 기업들의 수익에 직결되는 요소로 인식되고 있다. 이에 기업들은 고객들의 니즈를 신속하고 정확하게 파악하기 위해, 기축적된 고객 관련 각종 데이터를 활용하려는 시도를 강화하고 있다. 기존 시도들은 주로 구매 행동 예측에 중점을 두었으나 고객 행동의 전후 과정을 해석하는데 있어 어려움이 존재했다. 본 연구에서는 고객이 구매한 상품을 확정 또는 환불하는 행동을 취할 때 해당 행동이 발생하는데 있어 어떤 요소들이 작용하였는지를 파악하고, 어떤 고객이 환불할 지를 예측하는 예측 모형을 새롭게 제시한다. 예측 모형 구현에는 트리 기반 앙상블 방법을 사용해 예측력을 높인 XGBoost 기법을 적용하였으며, 고객 의도에 영향을 미치는 요소들을 파악하기 위하여 대표적인 설명가능한 인공지능(XAI) 기법 중 하나인 SHAP 기법을 적용하였다. 이를 통해 특정 고객 행동에 대한 각 요인들의 전반적인 영향 뿐만 아니라, 각 개별 고객에 대해서도 어떤 요소가 환불결정에 영향을 미쳤는지 파악할 수 있었다. 이를 통해 기업은 고객 개개인의 의사 결정에 영향을 미치는 요소를 파악하여 개인화 마케팅에 사용할 수 있을 것으로 기대된다.

With the spread of untact culture resulting from the Covid-19 pandemic, the size of the car camping market has expanded to minimize contact with others. As a result, SUVs have exceeded sales of sedans, and sales of recreational vehicles (RVs) have increased by 101% compared to the same period last year. Despite the explosive increase in demand for car camping, research on car camping has not matched this increase. Therefore, in this study, we intended to conduct a study focused on car camping users. According to a survey of Naver's famous car camping cafe, it was difficult to find articles, maps, and websites with car camping places. Analysis of car camping websites showed that most only post information about the camping itself, so details of car camping places were not available. Furthermore, according to a survey derived from related prior studies and literature surveys, most users urged solutions to the problem of unauthorized garbage dumping in the car camping locations. In addition, car camping users wanted to receive information on amenities near the car camping places. Therefore, we aimed to establish a car camping website that provides basic information on car camping places and nearby convenience facilities. Moreover, to solve the problem of garbage dumping, we provided a category wherein users can post pictures of clean camping campaigns. We also developed a business model utilizing the certification process of clean camping. The business model is designed with a structure wherein car camping users are rewarded through the clean camping certification process. Compensation for clean camping certification was proposed to be provided through partnerships with domestic automakers, Korea Tourism Organization, and Small Business Market Promotion Agency.

많은 이들이 지겹게 듣던 것이 바로 엊그제인데 이제 또 우리는 e-비즈니스와 e-상거래라는 새로운 용어들을 다루어야 한다. 이 용어들이 의미하는 바는 무엇인가? 이 용어들은 같은 것을 나타내는가? 이들은 서로 관계가 있는가? 그저 컨설턴트가 발생시킨 과대 선전에 불과한가? 이 용어들이 도서관 및 정보계에 영향을 미치게 될 것인가? CNS(컴퓨터네트워크서비스)에 종사하는 사람들과의 이전에 인터뷰들에서 그들은 동향을 정확히 읽어내는 비젼을 가진 사람들이며 실제적인 해결안을 가지고 있는 것으로 나타났었다. 그래서 나는 콜린 아이브즈와 이야기를 나누기 위해 정보관리 제트기를 타고 요크셔로 가서 실라 블랙의 노래를 바꾸어 이거 도대체 무엇인가요 콜린 하고 물어봤다.

Due to the changes in market place, new business types(e.g. e-business) have been rapidly emerged and increased. However, those new business types have not much been emerged n shipping and port related industries, and adoption rate of e-business in this area is very low, compared to other industries. Thus, to promote e-business in this area. many policies have been studied. However, most of previous studies have not been based on industrial structure, and results of these studies have mostly been case by case. Further, there have been no research based on the related theories. As a result, despite many of research and project for shipping and port related e-business, prominent achievements in this area have never to be presented. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed. For these reasons, it can be stated that, first of all, basic studies related to new business types in shipping and port are needed, and then, various policies based on results of those basic studies should be discussed. The aim of this study is to classify business types existed (or expected) in a port related industry, ship bunkering. This taxonomy was based on theories related to business layer(BL) and value chain(VC), and these BL and VC combination enabled to acquire all possible business types.

현재 ERP는 대부분 전통적인 기능 수행에 초점이 맞추어져 있다. 그러나 최근의 경영환경은 인터넷(internet)과 이를 기반으로 하는 전자상거래의 비약적 발전에 기인하여 e-비즈니스화를 추진하면서 제휴기관과의 관계증진, 고객관계의 혁신적 개선은 물론 조직내부의 업무프로세스의 획기적 개선을 통한 경쟁력 강화를 적극적으로 전개하고 있다. 한편 ERP는 SCM과 CRM 및 SEM(Strategic Enterprise Management)등으로 기능을 확대해감에 따라 21세기의 ERP는 e-비즈니스의 전략적 도구로 발전해 갈 것이다. 이를 위한 도구로 에이전트의 역할을 제안한다.

레지스트리는 웹을 통한 정보의 생산 분배, 발견을 가능하게 하는 기반 구조를 말한다. 이러한 레지스트리를 통해 동적으로 B2B 거래를 편리하게 할 수 있으며, 자원을 공유할 수 있게 된다. 따라서 레지스트리는 e-비즈니스 서비스에 핵심 기능이라고 할 수 있다. 그러나 현재 이러한 레지스트리들에 대한 개발이 독립적으로 개발되고 있으며, 따라서 이들 레지스트리간의 상호 연동이라든지, 사용자 입장에서의 레지스트리 이용은 제한점을 가질 수밖에 없다. 현재 SUN에서 JAXR이라는 패키지를 내놓고 있으며, 이 패키지를 이용하여 어떤 특정 레지스트리에 제한되지 않는 포괄적인 API를 사용하여 레지스트리를 검색하거나 저장할 수 있도록 하고 있다. 본 논문에서는 JAXR을 이용하여 여러 레지스트리를 효율적으로 검색할 수 있고, e-비즈니스 구축에 있어서 보다 넓은 유연성을 제공하며 높은 레벨의 서비스 구조를 제공하기 위한 시스템 구조를 제안했다.

Despite steady economic growth of e-learning industry, manpower is lacking in e-learning industry. In this study, We developed a new e-learning business model including open market portal system to solve this problem. The existing e-learning business models required complicated procedure for creating contents. Therefore it took long time and great expense. But in this study we developed the business model with open market portal system, it can support to make easily for e-learning contents. We analysed usefulness our program and other popular programs with thirty lecturers. As a result of survey, usefulness of our system is presented. The study suggests differently the student-centered business model and the lecturer-centered business model than existing e-learning business model had the manufacturing company-centered business model and the services-centered business model. We anticipate the new business model invigorate the e-learning industry.

The next generation of web applications will need to be larger, more complex, and flexible Agent-oriented systems have great potential for these e-commerce applications. Agents can dynamically discover and compose e-services and mediate interactions. Development of software agents with CBD (Component Based Development) has proved to be successful in increasing speed to market of development Projects, lowering the development cost and providing better qualify. In this thesis, we propose a systemic development process for software agents using component and UML (Unified Modeling Language). We suggest a etA (e-business Agent) CBD reference architecture for layer the related components through identification and classification of general agent and e-business agent. We also propose the ebA-CBD process that is a guideline to consider the best features of existing agent oriented software engineering methodologies, while grounding agent-oriented concepts in the same underlying semantic framework used by UML. We first developed the agent components specification and modeled it with Goal, Role, Interaction, and Architecture Model. Based on this, we developed e-CPIMAS (e-Commerce Product Information Mailing Agent System) as a case study that provides the product information's mailing service according to proposed process formality. We finally describe how these concepts may assist in increasing the efficiency reusability, productivity and quality to develop the business application and e-business agent.
