At a time when trend called complex cultural space has recently been taking place in public libraries, this study analyzed the importance-performance of users regarding the use factors of public library's complex cultural space. Based on the results of the analysis, this study attempted to broaden the understanding of the library users' use of this space, and to suggest directions on which factors should be improved. The results of the study were as follows: First, only 5 of 41 factors for library complex cultural space have higher satisfaction than importance, so it is necessary to promote balanced development with focus on priority improvements rather than a specific sector. Second, it is necessary to provide various programs and services in consideration of visit characteristics, such as the users of the library complex cultural space are mainly used by themselves (42%) or with their families (18.2%), also more people (50.5%) use weekday afternoons than 35%, including weekend mornings and afternoons. Third, among the five use factors related to space, the remaining items except for 'Compatibility of Computer / Equipment Use' are located in the first quadrant where both importance and satisfaction are high or in the fourth quadrant which shows higher satisfaction than importance. This is a result that shows that the library is fully performing the diversification and complexion of the space basically aimed as a complex cultural space. Fourth, it is necessary to improve the public library's complex cultural space in the future based on the analysis results of the result of analysis of the importance-satisfaction the use of factors using the IPA analysis.

We describe a novel method for improving the performance of the UCC retrieval using content reputation and user reputation. The UCC retrieval is a part of the information retrieval. The goal of the information retrieval system finds documents what users want, so the goal of the UCC retrieval system tries to find UCCs themselves instead of documents. Unlike the document, the UCC has not enough textual information. Therefore, we try to use the content reputation and the user reputation based on non-textual information to gain improved retrieval performance. We evaluate content reputation using the information of the UCC itself and social activities between users related with UCCs. We evaluate user reputation using individual social activities between users or users and UCCs. We build a network with users and UCCs from social activities, and then we can get the user reputation from the network by graph algorithms. We collect the information of users and UCCs from YouTube and implement two systems using content reputation and user reputation. And then we compare two systems. From the experiment results, we can see that the system using content reputation outperforms than the system using user reputation. This result is expected to use the UCC retrieval in the feature.

Knowledge Management (KM) is the systematic, explicit, and deliberate building, renewal, and application of knowledge to maximize an enterprise's knowledge-related effectiveness and performance from its knowledge assets. KM applies systematic approaches to find, understand, and use knowledge to create new capabilities, solve problems, enable superior performance, and encourage innovation. The purpose of this research is to identify the relationship of KM capabilities (KM infrastructures and KM processes) and organizational effectiveness and performance. An empirical research of the relationship of knowledge management capabilities and organizational effectiveness and performance is conducted from the information systems and knowledge management literature in order to access the following questions: (1) Does the knowledge management infrastructure contribute to the organizational effectiveness and peformance? (2) Does the knowledge management process contribute to the organizational effectiveness and peformance? The research design employs a mail survey questionnaire for gathering data from 500 firms in a number of industries. From a mail survey of 61 top managers of knowledge management, the results of empirical analyses provide the following major findings: (1) While the external effectiveness of organization is influenced by the cultural infrastructure of knowledge management, the overall performance of organization is influenced by the structural infrastructure of knowledge management. (2) While the external effectiveness of organization is influenced by the application and protection processes of knowledge management, the overall performance of organization is influenced by the knowledge acquisition process of knowledge management.

Morphological analysis is used for searching sentences and understanding context. As most morpheme analysis methods are based on predefined dictionaries, the problem of a target word not being registered in the given morpheme dictionary, the so-called unregistered word problem, can be a major cause of reduced performance. The current practical solution of such unregistered word problem is to add them by hand-write into the given dictionary. This method is a limitation that restricts the scalability and expandability of dictionaries. In order to overcome this limitation, we propose a novel method to automatically expand a dictionary by means of use-case analysis, which checks the validity of the unregistered word by exploring the use-cases through web crawling. The results show that the proposed method is a feasible one in terms of the accuracy of the validation process, the expandability of the dictionary and, after registration, the fast extraction time of morphemes.

When an organization adopts new technology, performance through the technology is expected to be decided depending on attitudes of the members, in that technology produces performance only if the members zealously use it. Therefore, the members need to devote themselves to acquire and use the new technology. This attitude of members is called "IT acceptance will" (Ranarajan et al., 2005), and this research is to examine the effect of an individual's "IT acceptance will" on performance. Thus, this research analyzes what increases IT acceptance will and what effect IT acceptance will has on stress due to uncertainty of an organization-job complexity and role conflict- through new IT adoption. This research conducted a survey from July to September in 2009, targeting employees of government offices and public institutions in Kyunggi and Kyungnam provinces. Then, a total of 370 was collected and the final 344 was selected for our research analysis. As a result, this research found out that personal innovation and client orientation improved an individual's IT acceptance will, which improved performance through new IT adoption. However, the new IT adoption also increased job complexity and role conflict, but negative effects of stress on performance was not found as IT adoption will diminished the stress. Based on this result, this research discussed practical and academic implications and the limitations.

Purpose: This study aims to explore the effects of personal characteristics, satisfaction, quality of care, role performance, image, awareness level of public hospitals perceived by community residents on use-experience of public hospitals. Methods: A cross-sectional survey was conducted with 2,100 community residents around 39 district public hospitals. The questionnaire was designed to collected information on personal characteristics and community awareness of public hospitals. The community awareness consists of 5 factors and 15 items. The data were collected utilizing call-interview by a survey company. Results: The personal characteristic and community awareness were shown significant differences between having use-experience and not-having use-experience of public hospitals (p<.001), except gender. As the results of multiple logistic regression, the significant variables of use-experience of public hospitals were satisfaction (OR=1.06 95%CI=1.010-1.116), quality of care (OR=1.07, 95%CI=1.016-1.134, level of awareness to public hospitals (OR=1.50, 95%CI=1.378-1.632), age (OR=0.43, 95%CI=0.236-0.785), education (OR=1.62, 95%CI=1.013-2.590), type of medical security (OR=0.37, 95%CI=0.142-0.945). Conclusions: Public hospitals have to effort to improve community awareness through providing quality of care, and role performance. It is possible to support them by the Central and Local Government.

Recently, the use of Geographic Information System in each field of our society is on the increase according to the development of the Internet. But, thereis a problem of the user access latencies, the network traffic, and the server overload in Internet Geographic Information System because spatial data are transferred in large volumes. In this paper, we propose a cache algorithm on client side to solve the above problems. The proposed algorithm demonstrates the performance improvement over known studies by utilizing unit time and spatial proximity. In addition, this paper conducts a performance evaluation to measure the improvement in algorithm efficiency and analyzes the results of the performance evaluation. When spatial data queries are conducted, according to our performance evaluation, hit rate has been improved over the existing algorithms.
