This research develops, and empirically test a model for explaining/predicting the Determinants and Satisfaction of Portal Cite in Internet Initiation Page. Also this paper describes a theoretical model for investigating the service quality satisfaction in the Internet Initiation Page. This research is the first to empirical test the causal relationships in determinants of Portal Cite. The model of the satisfaction for Portal Cite are tested here using data from 224 samples. Based on the research model, a comprehensive set of hypotheses is formulated and a methodology for testing them is outlined. some of the hypotheses are tested empirically to demonstrate the applicability of the theoretical model. In examining the relationships of the determinants factors, satisfaction show in significantly by Convenience, Information Provided, Entertainments, Interaction but that show in not significantly by the Trustworthiness, In addition, Portal Cite in Internet Initiation Page shows indirect effect between customer satisfaction and referral.

본 논문에서는 CITE를 포함한 2차 반복 학습제어 방법이 수렴 성능의 향상과 외란에 대한 강인성 향상에 덧붙여 초기 오차가 있음에도 불구하고 이를 극복할 뿐만 아니라 기존의 알고리즘보다 더 빠른 수렴 능력이 있음을 확인한다. 또한 불안정한 결과를 낳는 높은 학습 게인의 경우에도 CITE를 추가한 본 학습제어 방법에 의해 안정화됨으로써, 빠른 수렴 특성과 강인성 향상을 가져올 수 있음을 보인다. 그리고 본 알고리즘을 선형 시변 시스템에 대해 적용한 시뮬레이션 결과를 통해 초기 오차의 극복 능력이 뛰어남을 확인하고, 아울러 각 학습 게인들이 수렴 속도와 안정성에 미치는 영향을 상세히 분석한다.

This study deals with activities in internet, including activities on consumer counseling, exchange of consumer information, and anti-sites. Among consumers having utilized those three types of internet sites, this study examines whether their satisfactions on them differ depending on their socio-demographic characteristics and types of activities and also explores which factors critically influence consumer satisfactions. According to the results of this study, consumers' satisfactions were higher when consumers evaluated counselors were objective, rapid, and reliable. Thus, Counselors must be more efficiently classify counseling contents, systematically manage, rapid, active and concrete answers for consumers applying for counseling. Second, in the case of consumer information site, the consumer satisfaction turns out to be positively related with exchange of consumer information, rapid provision of information, and reliability. Connection of relevant specialized information, encouragement of active information exchange among consumers, and objectivity and specialty in consumer information site are necessary to increase the quality of internet consumer information cite. Third, in the case of anti site, consumer satisfaction is higher in cases of consumer being joined in anti-site and in cases of objective and reliable sites. In order to facilitate the utilization of anti-sites, those solutions include systematic classification and management of writings listed in the site, active management of the site managers, reducing criticisms on the writings listed and objectivity of information provided, and active searches for solutions. Finally, in order to preserve consumer sovereignty, policy suggestions include improvements of service qualities provided in internet sites, active advertisement, improvement of site management through charging some fees for users, enhancing specialties.

This paper aims to assess the feasibility of a new and less-focused type of online sociability (the watching network) as a useful information source for personalized recommendations. In this paper, we recommend scientific articles of interests by using the shared interests between target users and their watching connections. Our recommendations are based on one typical social bookmarking system, CiteULike. The watching network-based recommendations, which use a much smaller size of user data, produces suggestions that are as good as the conventional Collaborative Filtering technique. The results demonstrate that the watching network is a useful information source and a feasible foundation for information personalization. Furthermore, the watching network is substitutable for anonymous peers of the Collaborative Filtering recommendations. This study shows the expandability of social network-based recommendations to the new type of online social networks.

The purpose of this study is to analyse theses and dissertations cited in research literature, particularly subjects, age, origin, and frequency of use of them, and kinds of papers that cite them. The theses and dissertations cited in the journal articles and theses dissertations in the fields of library science, information science and bibliography are analysed in this study. The maj or conclusions made in this study are summarised as follows. (1) Theses and dissertations form $5.6\%$ of the total citations. (2) $87.1\%$ of the cited theses and dissertations are found in theses and dissertations and $12.9\%$ in journal articles. (3) Most of research papers cite less than six theses and dissertations. The average number of theses and dissertations cited in a research paper in 2.7. (4) Most of the cited theses and dissertations are found in research papers from their own field and $24.5\%$ in those from other fields. (5) Researchers prefer to cite recently produced theses and dissertations $63.5\%$ of the total citations are those produced within three years in the past. (6) The theses and dissertations form most part$(89.0\%)$ of the total citations. 88.9% of the cited foreign theses and dissertations are found in theses and dissertations, and $11.1\%$ in journal articles.

The commercial buildings greening can generate multiple benefits to achieve a sustainable building and business environment. However, a comprehensive systematic review of commercial buildings greening across multiple disciplines has yet to be reported. This study conducted a systematic analysis of 39 literature on commercial building greening from Web of Science over the past 19 years and utilized CiteSpace to visualize the academic evolution and trends in this field. Key findings were: 1) The number of publications in the past five years has increased, indicating that commercial building greening research has received widespread attention. 2) The large number of publications means that the research field of commercial building greening is relatively broad. 3) The study of commercial building greening has become a global participation and cooperation research topic. The top cooperating countries mainly come from the United States and Europe, while the differences in cooperation between institutions in developing countries are less significant. 4) The greening of commercial buildings is more related to research on behavioral activities. 5) The research on commercial building greening has developed from architecture and plants to interdisciplinary fields, including psychology, economics, and management. 6) The cost of commercial buildings greening is generally an obstacle to installation. This study provides specific references for stakeholders and plays a crucial role in determining the evolution of commercial building greening research and predicting future research needs and opportunities.

In this article we propose using mathematical models of signals in wireless communication systems with autocorrelation reception of modulated ultra-wideband signals. For the transmission of information content, the method of positional-time coding is used, in which each information bit is encoded by hundreds of ultrashort pulses that arrive within a certain sequence. Comparative analysis has shown that the best noise immunity of the systems considered in this paper is the communication system, which uses the time separation of the reference and information signals.
