In this paper, we present the film bulk acoustic resonator (FBAR) devices fabricated by considering the effects of annealing temperature on zinc oxide (ZnO) film growth characteristics. In order to determine the annealing temperature and annealing time at which the ZnO film can have good material properties, the several resonators containing ZnO layers were fabricated and annealed at various temperatures from 27$^{\circ}C$ to 30$0^{\circ}C$ in Ar gas ambient. The effects of the annealing temperature and annealing time on the ZnO film properties were comprehensively studied in order to further improve the resonance characteristics of FBAR resonators.

Although the internet community(IC) has been recognized as an increasingly important for better understanding and relationships with customers, few evidence has been accumulated what factors influence IC success. This study posits the characteristics and individual characteristics as key determinants of IC success, and related hypotheses were tested using 230 data. Using user loyalty as a surrogate of IC success, this study found that the three key characteristics of IC-focus, interactivity, and cohesion levels-significantly influence the community user's loyalty. In addition, individual characteristics including personal value propositions(e.g, challenge/ambitious value, economic/rational value) and absorption tendency(e.g., flow level) affect their loyalty levels. This study also found that the determinents of IC user's loyalty defer with different types of community such as entertainment, relationships, and information/opinion sharing communities. These findings are hopefully helpful for the successful and contingent management of IC buildings and operations.

It is generally agreed that realizing the full potential of the internet shopping mall(ISM) requires careful identification of customer needs and expectations. However, a quantitative framework to explain and predict users' behavior toward ISM has not been well established because the research on the user acceptance of ISM is still in its infancy. This study proposes a model which uses factor analysis to identify factors of ISM characteristics and individual characteristics affecting user acceptance of ISM. Predictive models based on the multiple regression analyses select the factors and their interactions with individual characteristics that significantly influence user acceptance. Results show that five factors including economy, convenience, credibility, reliability, information risks, and performance risks affects user acceptance. In addition, individual differences in terms of innovativeness, playfulness, and recreational shopping traits have both direct and interaction effects on user acceptance. The implication of this study is that, although user attitudes towards ISM characteristics in general are important to their acceptance behavior, the level of importance depends upon different user groups.

This study examines which factors are urging Korean companies to participate in e-marketplaces. By adding interorganizational factors, we extended an innovation-theory-based research model that is often applied to study the information technology adoption. 71 questionnaires from 720 Korean manufacturing companies were collected. Independent variables of the research were environmental, organizational, innovation, and interorganizational characteristics. We found that the environmental characteristics, innovation characteristics, and interorganizational characteristics have insignificant effect on the participation of domestic companies in e-marketplaces whereas the organizational characteristics have significant relationship with the participation in e-marketplaces. The result implies that many Korean companies take wait-and-see strategy in the forming stage of e-marketplaces, However, IT infrastructure and the support of top management for IT play very important role in adopting e-marketplaces.

This study explores the textual characteristics, more precisely the quantity and diversity of nouns, of Japanese prime ministers' Diet addresses. In the field of stylistics, textual characteristics independent of the content have been examined with the aim on detecting the authors, genres, and chronological variations of texts. This study focuses instead on textual characteristics related to the content of texts, namely the quantity and diversity of nouns, because our aim is to analyze texts to better understand two political phenomena: (a) the difference between the two types of Diet addresses delivered by Japanese prime ministers, and (b) the perceived changes made to these addresses by two powerful prime ministers. It is a case study of the microscopic characterization of texts, which has become more and more important with the expansion in the scope of stylistics and the production of a wide variety of new types of texts following the advent of the Web.

This study analyzed the influence of social distance and visual information on consumers' fashion style preferences in terms of information characteristics and providers. Data were collected from 521 females in their twenties and thirties who had experience using SNS. The empirical study results were as follows. First, with other factors of exposure under control, the social distance of information characteristics and providers showed a significant impact on fashion style preferences only when social distances were close. Second, the impact of social distance varied depending on the consumer's characteristics. This proved that innovation had significant negative influences, while conformity and informational sensitivity to others showed positive influences on the effects of social distance in terms of information characteristics. Innovation and fashion leadership also showed a negative influence on the social distance effect in terms of information providers. Third, conformity, informational sensitivity to others, and fashion leadership, proved to have a significant impact on the acceptance of eWOM in fashion styles, but innovativeness and normative sensitivity to others did not have a significant influence. This study can be used as baseline data in SNS marketing strategies for vitalizing information spread through eWOM.

This study starts from the question if the characteristic of existing conventional site-specificity can be applied to the modern city space in information media era as it is. The evolution and spread of media technology acted as the catalyst which establishes the identity of an individual and promotes the social sense of belonging as the new type of community member as well as expanded the communication territory of man. Moreover, as the perfect merge of third dimensional space with second dimensional media was accomplished, the meaning of city as the place is getting changed and extended to city space as the information platform which integrates and intermediates the various information composing city. Hereupon, this study is willing to analyze the limits which the characteristics of physical, active and meaningful elements which are the forming primary factors in the existing place theory have and establish the new meaning of city as the place through the case studies which are applied by the characteristics of hyper spacio-temporal, mobility and polysemy as the characteristics transformed by information platformization of city space.

Supply chain management(SCM) helps firms in integrating their business by collaborating with other value chain partners to meet the unpredictable demand of the end user. Agility is the fundamental characteristic of a supply chain needed for survival in turbulent and volatile markets, which are becoming norms as product life cycles shorten and environmental forces create additional uncertainty resulting in higher risk in the supply chain management. Literature reviews reveals various factors that could affect the agility. The objective of this study is to derive interdependence, partnership, quality of information, joint problem solving, modelize the mutual influential relationship between them, and look into the influential relationship influencing the agility. To test the proposed model, we used a data set generated from survey. Date analysis was conducted using 122 respondents. We used structural equation model (SEM) implemented in partial least square(PLS). The results of this study can be summarized as follows. Interdependence had a significant impact on partnership. Partnership had a significant impact on quality of information and joint problem solving. Quality of information had a significant impact on joint problem solving. Quality of information and joint problem solving had a significant impact on agility. This study diagnoses that Inter-organizational relationship characteristics are important for supply chain agility. Inter-organizational relationship characteristics are considered as an essential factor for supply chain agility.
