Due to rapid increase in number of Internet users, the volume of domestic Internet shopping is expanding dramatically. Although the Internet shopping mall business is steadily growing, it has structural weakness, and in general, the business does not generate profit. In this context, this research identifies characteristics of the Internet shopping non-adopters, and suggests strategies to strengthen competitiveness of domestic Internet shopping malls and to create a new demand. Analysis of MCR data in 2007 showed that out of 4,298 respondents, 2,206 people adopted Internet shopping (51.3%). and 2,092 did not (48.7%). The survey measured 28 items regarding a consumption pattern and a lifestyle of the Internet users, and the analysis result showed that the pattern can be categorized in seven groups. Based on the analysis, the research suggests that the domestic Internet shopping malls adopt strategies to increase consumers' access frequency to tile Internet service, provide high-end goods, diversify transaction methods, make online shopping more convenient, cater to diversified consumer demands based on demographic data, provide price comparison more Internet shopping mails, and provide sufficient and useful information to consumers.

정보통신기술의 발달로 인해 도래한 디지털 경제는 인터넷 비즈니스라는 새로운 사업영역을 창출하였다. 인터넷 비즈니스는 다른 사업과 달리 매우 유동적인 시장점유율 변동이 나타나는 비즈니스 영역으로, 기업들은 시장 내의 경쟁 환경 및 경쟁 구조를 정확히 이해하여야만 불안정한 인터넷 시장 환경에 효과적으로 대처해 나갈 수 있게 되었다. 이에, 본 연구는 한국 인터넷 비즈니스내의 인터넷 사이트 간 경쟁을 각 사업 분야 별 시장점유율에 기초하여 실증분석 하였다. 이를 통해 인터넷 사이트들의 점유율 변동 추이를 살펴보고, 시장 선도 사이트들의 시장 지배력과 개별 시장의 경쟁 구도 등을 살펴보았다. 이러한 연구결과는 각 기업의 인터넷 사이트 담당자에게는 해당 시장의 경쟁양상과 경쟁구조를 파악할 수 있는 기회를 제공하고, 인터넷 분야로 새롭게 진출하려는 기업의 마케터들에게는 자사의 사업 진출 방향에 대한 기초자료로 활용될 수 있을 것이다.

Despite our extensive understanding on the Internet business and widely understood first-mover advantage. it is not clearly answered yet whether an internet firm can enjoy the first-mover advantage in the new environment of the Internet. This is mainly because the Internet marketplace itself has a complex combination of various business models, ranging from a simple channel-extension to a whole new business model. Based on new theoretical development on the first-mover advantage, we empirically test whether being an early mover in the Internet environment materially affects firm performance, using clickstream data from Korea where broadband Internet installation is ranked as top among OECD countries. Our results show the effectiveness of first-mover advantage on the web does not exist, regardless of its business model and competitive environment. This result expands our understandings on the e-business, not to mention of the real feature of first-mover advantage.

Purpose - This study attempts to examine the new concept of mobile internet users' lifestyles through empirical analyses based on the i-VALS concept study that had classified the VALS program, among others, aiming at internet users. Research design, data, and methodology - A total of 300 questionnaire copies were distributed, of which 273 were collected; only 244 were used for the empirical study after excluding some inappropriate or unusable ones. To analyze the data collected, the SPSS/WIN 19.0 statistical package was used, and the lifestyles of mobile internet users were reclassified after analyzing the reliability and validity of the responses. Results - The study involved the empirical analyses of the new concept of the mobile internet users' lifestyles based on the i-VALS concept study, of which the subjects were internet users. Conclusion - It is possible to provide enterprises with more systematic and objective fundamental data based on the characteristics of mobile internet users' lifestyles, to help enterprises with their establishment of market segmentation strategies for promoting mobile shopping in the future.

본 논문에서는 UCLA IRL의 BGP 데이터, IRR, IXP 데이터를 이용하여 한국 AS 수준 인터넷 위상 데이터를 구축하였다. 그리고 지금까지 소개된 인터넷 위상 생성 모형(Waxman, BA and GLP)를 이용하여 한국 AS 수준 인터넷과 동일한 노드수를 가지는 위상 데이터를 생성한 뒤, 각각의 모형이 얼마나 한국 AS 수준 인터넷 위상을 잘 묘사하는지 분석하였다. 본 연구를 통해 기존의 인터넷 위상 생성기 모형들은 한국 AS 수준 인터넷을 잘 묘사하지 못하는 것을 확인하였다.

The Internet was created as a decentralized and autonomous system of interconnected computer networks used for data exchange across mutually trusted participants. The element technologies on the Internet, such as inter-domain and intra-domain routing and DNS, operated in a distributed manner. With the development of the Web, the Web has become indispensable in daily life. The existing web applications allow us to form online communities, generate private information, access big data, shop online, pay bills, post photos or videos, and even order groceries. This is what has led to centralization of the Web. This centralization is now controlled by the giant social media platforms that provide it as a service, but the original Internet was not like this. These giant companies realized that the decentralized network's huge value involves gathering, organizing, and monetizing information through centralized web applications. The centralized Web applications have heralded some major issues, which will likely worsen shortly. This study focuses on these problems and investigates blockchain's potentials for decentralized web architecture capable of improving conventional web services' critical features, including autonomous, robust, and secure decentralized processing and traceable trustworthiness in tamper-proof transactions. Finally, we review the decentralized web architecture that circumvents the main Internet gatekeepers and controls our data back from the giant social media companies.

본 연구의 목적은 정보화에 대한 적응 및 확산 정도가 상대적으로 느린 고령층의 인터넷 이용 실태를 사회경제적 특성에 따라 분석하는 것이다. 조사대상은 대구경북지역에 거주하고 있는 60세 이상의 고령층으로 한정하여 주로 1:1 설문조사를 통하여 자료를 수집하였다. 수집된 자료는 고령층의 성별, 최종학력, 경제상태, 건강상태, 종교유무, 그리고 생활만족이라는 사회경제적 특성으로 구분하여 이들의 인터넷 이용빈도, 이용동기, 활용능력 그리고 인터넷의 유용성 여부를 각각 분석하였다. 분석결과 다양한 사회경제적 특성에 따라 고령층의 인터넷 이용에 통계적 유의수준에서 차이가 발견되었다. 이 연구결과는 향후 정보화 사회로의 구현에서 소외될 수 있는 고령층의 정보격차 해소 혹은 노인복지 정책개발의 기초적인 자료로 사용되어 질 수 있을 것으로 기대한다.

Big data management is becoming an increasingly important issue in both industry and academia of information science community today. One of the important categories of big data generated from software systems is log data. Log data is generally used for better services in various service providers and can also be used to improve system reliability. In this paper, we propose a novel big data management architecture specialized for log data. The proposed architecture provides a scalable log management system that consists of client and server side modules for efficient handling of log data. To support large and simultaneous log data from multiple clients, we adopt the Hadoop infrastructure in the server-side file system for storing and managing log data efficiently. We implement the proposed architecture to support various client environments and validate the efficiency through measurement studies. The results show that the proposed architecture performs better than the existing logging architecture by 42.8% on average. All components of the proposed architecture are implemented based on open source software and the developed prototypes are now publicly available.

The advent of Internet of Things (IoT) and the evident inadequacy of Cloud networks concerning management of numerous end nodes have brought about a shift of paradigm giving birth to Fog computing. Fog computing is an extension of Cloud computing that extends Cloud resources at the edge of the network, closer to the user. Cloud computing has become one of the essential needs of people over the Internet but with the emerging concept of IoT, traditional Clouds seem inadequate. IoT entails extremely low latency and for that, the Cloud servers that are distant and unknown to the user appear to be unsuitable. With the help of Fog computing, the Fog devices installed would be closer to the user that will provide an immediate storage for the frequently needed data. This paper discusses data migration between different storage types especially between Cloud devices and then presents a mechanism to migrate data between Cloud and Fog Layer. We call this mechanism Adaptive Deadline-Aware Scheme (ADAS) for Data migration between Cloud and Fog. We will demonstrate that we can access and process latency sensitive "hot" data through the proposed ADAS more efficiently than with a traditional Cloud setup.
