This paper introduces Zigbee based ubiquitous service. Most of ubiquitous services require the position information. Positioning algorithms utilize the transmission characteristics of the signal. Zigbee based positioning researches have been conducted mainly for the spatial factors inside the building. This paper proposes the possibility to consider the temporal factors of Zigbee signal and analyzes empirically the signal characteristics influenced according to the temporal factors as well as the spatial factors for ubiquitous services based on Zigbee sensor network.

The purpose of this study was to identify the variables which could characteristics the New Young Generation (NYG), to investigate the relationship between level of NYG characteristics and information searching related to underwear purchasing, and the differences level of the NYG characteristics according to demographic variables (sex, grade, major), and examine the casual relationships of demographic variables (sex, place of growing background, parent's education) and level of the NYG characteristics on information searching related to underwear purchasing. The subjects were 723 college students (female = 324, male=398) living in Seoul and Kyuggi were participated in this study. The NYG is limited to person who born after 1970's. The result of this study were as follows; 1. Five factors of New Young Generation oriented characteristics were identified; F.1 'Info-telecommunication(Info-Telecom)'; F.2 'Family and Marriage'; F.3 'Consumption pattern'; FA 'Self-centered (Individualism)'; F.5 Work/Career oriented. 2. The relationship between the NYG characteristics and information search in underwear purchasing were significanted. 3. In demographic variables, gender, grade, and major were partially significant differences. 4. In male students, the result of the casual relationship between demographic variables with NYG characteristics and the level of the NYG in underwear purchasing showed that grade, background of grownplace, level of parent's education were significanted the high level of info-telecom factor associated with higher grade, city-grown, higher level of parent's education. In conclusion, the result showed that the level of NYG characteristics was significant to male students and specially for grade older students. The background of parent's education level was the another important variables to predicting the NYG characteristics. Finally the higher the NYG characteristics, the more information search in underwear purchasing.

The purpose of this study is to confirm whether the fit between the task and the information characteristics makes any effects on the user satisfaction. The task is defined as two sub-constructs representing the degree of exception and analyzability. The information characteristics is divided into the degree of aggregation, scope and timeliness of information. User satisfaction was used as a surrogate measure of the performance of information systems. The computer self-efficacy was used to control any confounding effects. Field research method using questionnaires was employed to empirically investigate the relationship among the variables. Findings of the study are summarized as follows: the fit between the task and the aggregation of information and between the task and the scope of information turned out to have significant effects on information system performance. The implication of such results is that under highly exceptional or less analyzable task environment, less-aggregated or broad information is more appropriate.

This paper is an exploratory study to investigate the influence of characteristics of local government web-sites on user satisfaction and trust. The objective of this research is to identify the characteristics of local government web-sites influencing on user satisfaction and trust, and determine how they affect user satisfaction and trust. From the literature review, we identify four characteristics which are expected to influence on user satisfaction: technical, information, customer-oriented, and work-performing characteristics. In addition, we develop research model that the four characteristics are expected to affect user satisfaction and trust via users' perceived values. The results of the research are as follows. The technical, customer-oriented, and work-performing characteristics significantly affects perceived values, which significantly affected user satisfaction and trust. Perceived value is partially mediated by user satisfaction in affecting user trust. The characteristics of local government web-sites affecting perceived values differed partially by the purpose of visitor. As for the personal goal, the technical, customer-oriented, and work-performing characteristics significantly affect perceived values, with the technical and customer-oriented characteristics having more significant effects. As for the business goal, the technical, information, work-performing characteristics significantly affected perceived values, with information characteristics having more significant effects.

In this paper, we present effective methods for automatic music recommendation system which automatically recommend music by signal processing technology. Conventional music recommendation system use users’ music downloading pattern, but the method does not consider acoustic characteristics of music. Sometimes, similarities between music are used to find similar music for recommendation in some method. However, the feature used for calculating similarities is not highly related to music characteristics at the system. Thus, our proposed method use high-level music characteristics such as rhythm pattern, timbre characteristics, and the lyrics. In addition, our proposed method store features of music, which individuals queried, to recommend music based on individual taste. Experiments show the proposed method find similar music more effectively than a conventional method. The experimental results also show that the proposed method could be used for real-time application since the processing time for calculating similarities between music, and recommending music are fast enough to be applicable for commercial purpose.

The main purpose of this study is to analyze the relationships between the R&D characteristics and R&D performance for Korean enterprises. We divided R&D performance into technological and business launching performance and analyzed four R&D characteristics' effect on the performance. The empirical analysis results can be summarized as follows: First, R&D characteristics of enterprises show a strong relationship with R&D performance in the case of R&D process control. Second, firm capability and information routine positively affect to technological performance at 0.1 significant level but not showing significance in the case of business launching performance. Third, managerial support negatively affects to technological performance but dose not show statistical significance. Its effect on business launching performance, however, shows positive and significant effect. This result is expected to be highly suggestive for establishing the effective R&D strategies of enterprises and also the relevant overseas marketing plan to support R&D planning.

A venture business plays important roles in the economy of a developing nation. It makes highly value-added product, increases employment and improves the industry structure. The objective of this study is to derive the financial and non-financial characteristics from venture businesses, which determine a highly successful business group or a less successful business group. The firm characteristics are composed of 21 financial(liquidity, leverage, cash flow, activity, productivity, and etc) and 34 non-financial characteristics(manager, technology, marketability and credibility variables), which have been considered as the key characteristics for venture business by the existing literature. All financial ratios and non-financial characters play a role of making discriminations between a highly successful and a less successful group. Because there are not generally accepted definitions, classifying a highly successful and a less successful venture business is a very difficult problem. Operational definitions have many problems but we have no choice in current stage.
