As the Internet is more embedded in people's lives, users draw on new Internet applications to express themselves through user-created contents(UCC). UCC is defined as content that is made publicly available over the Internet, reflects a certain amount of creative effort and is created outside of professional practices. This study describes the rapid growth of UCC as well as its increasing role in network-based communication. Based on the definition of UCC and the structure of emerging value chain, a taxonomy of UCC businesses is presented : UCC e-marketing business, UCC publishing business, UCC e-retailing business, and UCC development software business. This paper concludes with implications for platform and internet access providers.

2000 년대 초반부터 글로벌화에 따라 화상회의 시스템이 정부와 기업에 중요한 업무지원도구로 확산이 되고 있다. 그 동안은 화상회의는 기업이라는 제한된 울타리에서 1:1 또는 다자간의 회의를 위한 도구로 만족을 하였지만 점차 화상회의를 상업용, 가정용으로 적극적인 활용을 모색하는 추세이다. 또한 기존의 인터넷, 모바일 등을 이용한 비즈니스 모델은 발전의 한계점에 도달하였으며, 고객들의 새로운 요구에 부응하기 위하여는 화상회의를 이용한 비즈니스 모델의 출현이 요구되는 시점이다. 본 연구에서는 화상회의를 이용한 비즈니스의 확산을 위하여, 화상회의 비즈니스 모델의 구조를 설계하였다. 또한 설계를 적용할 수 있는 환경연구로서, e-커머스에 대응한 화상회의 상거래, 즉 v-커머스를 지향한 기술 및 서비스 구성, 비즈니스 모델의 유형과 고객가치속성, 모델의 구성요소, 적용사례 등을 제시하였다.

컴포넌트 기술은 재사용성을 기반으로 어플리케이션 개발의 생산성을 높일 수 있어 소프트웨어를 신속하고 효과적으로 개발할 수 있는 기술로써 채택되고 있으며, 특히 EJB 컴포넌트는 자바를 기반으로 하며 산업계에서 널리 이용되고 있는 기술이다. 이러한 컴포넌트의 유형은 크게 비즈니스 컴포넌트와 기능별 컴포넌트로 분류할 수 있으며 비즈니스 컴포넌트는 특정 응용분야와의 상관성이 커짐에 따라 비즈니스 공용 컴포넌트, 비즈니스 핵심 컴포넌트, 비즈니스 응용 컴포넌트로 구분하고 있다. 본 논문은 일반 Web Application 에서 업무 구현상 필요성 혹은 솔루션 제품의 해외 판매 시 필요로 하는 비즈니스 공용 컴포넌트인 Globalization 컴포넌트의 개발과정과 실제 적용 가능성 및 효용성 측면을 제시한다.

새로운 경영방식을 가능하게 하는 혁신적 정보기술의 하나로서 최근 차세대 인터넷으로 불리는 3차원 온라인 가상공간인 메타버스가 부상하고 있으며, 이를 구현하기 위해 증강현실이나 멀티모달 방식 등으로 자연스러운 인터페이스를 실현하려는 노력이 주목할 만하다. 그러나 아직 메타버스에 대한 학술적 접근이나 메타버스 기반의 u-Biz 혁신에 대한 연구는 미흡한 실정이다. 따라서 본 연구의 목적은 e-Biz와 u-Biz 및 메타버스 현황을 살펴보고, 기존의 비즈니스 유형을 융 복합하여 메타버스 기반의 차세대 u-Biz를 의미하는 메타비즈니스 및 그의 유형을 제안하는 것이다.

The mobile internet service market is growing very rapidly in Korea. This study outlines the current state of mobile internet services and analyzes the mobile contents types of media companies, especially newspapers, broadcasters and internet portal firms. As a result of this study, media companies provide generally different types of news and information for free and they are eager to develop the new mobile business models to maintain their power in new media. But mobile content distribution is still in the early stages due to the lack of clear business models. To satisfy the consumer's needs and to maintain the competitive advantages, the media companies should develop new business models and cooperate with other market participants to reduce the barriers in the mobile internet service market.

With the increasing emphasis on anomaly detection across various fields, diverse anomaly detection algorithms have been developed for various data types and anomaly patterns. However, the performance of anomaly detection algorithms is generally evaluated on publicly available datasets, and the specific performance of each algorithm on anomalies of particular types remains unexplored. Consequently, selecting an appropriate anomaly detection algorithm for specific analytical contexts poses challenges. Therefore, in this paper, we aim to investigate the types of anomalies and various attributes of data. Subsequently, we intend to propose approaches that can assist in the selection of appropriate anomaly detection algorithms based on this understanding. Specifically, this study compares the performance of anomaly detection algorithms for four types of anomalies: local, global, contextual, and clustered anomalies. Through further analysis, the impact of label availability, data quantity, and dimensionality on algorithm performance is examined. Experimental results demonstrate that the most effective algorithm varies depending on the type of anomaly, and certain algorithms exhibit stable performance even in the absence of anomaly-specific information. Furthermore, in some types of anomalies, the performance of unsupervised anomaly detection algorithms was observed to be lower than that of supervised and semi-supervised learning algorithms. Lastly, we found that the performance of most algorithms is more strongly influenced by the type of anomalies when the data quantity is relatively scarce or abundant. Additionally, in cases of higher dimensionality, it was noted that excellent performance was exhibited in detecting local and global anomalies, while lower performance was observed for clustered anomaly types.

The purpose of this study is to propose an open source GIS software business model for the revitalization of Korean open source GIS software industry. In this study, we categorized the types of open source software business models and developed an open source software business strategy suitable for GIS companies in Korea. To propose a business model, we applied the business model canvas which is often used in the area of business studies to analyze new business models. We tried to develop the open source GIS business model through both interviews and case studies with Korean open source GIS software companies. We propose three different types of open source GIS software business models such as distributor model, producer model, and 3rd party service provider model as follows: first, the companies which belong to distributor model can carry out business by providing professional services in the market of open source software. Second, the companies which belong to producer model can sell their products to the global market as well as the domestic market. Lastly, given the growing interest in domestic open source software, the number of third-party service providers is likely to continue to increase in the future. Therefore, it is expected that the companies which belong to the third party service provider model will be able to develop various business models by securing the technology.

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 in port and logistics 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 am 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.

The 'Grand Challenge' in the global level raises fundamental questions on the role of private firm as a profit maximizer. From the new perspective, firms are recognized as a social entity with social and environmental responsibility. Particularly, the importance of transition-orineted firms, which pursue an objective of socio-technological system transition, have increased. These environmental changes request a new understanding on the identification of firms and the evolution of sustainable business model from the technological innovation perspectives. This paper aims on the new understanding on the motivation of firms who participated on the sustainable system transition and the proposal of 'transition-oriented firms' concept. Based on literature survey, this paper reviews the role of firms in the process of socio-technological system transition, the cases of transition-oriented firm, the types of sustainable business models and their strategies.
