  • Information center represents an important source which seems very well suited for knowledge management investigation. Information center is knowledge intensive and the use of advanced technology may transform the knowledge of business processes for delivering an unique capabilities in an organization. To exam knowledge management, organization culture, importance of knowledge, and support of information technology were identified as potential predictors of knowledge management support in information center. Three hypotheses have been tested with 43 database management specialist surveys. This study presents that the level of information sharing and knowledge exchange is significantly influenced by the extent support of information technology.

  • The artifacts in sonography is not always harmful. Sometimes it is beneficial for the evaluation of the water contents of the soft tissue and estimating the degree of inflammation and character of the regenerated tissue indirectly using artifacts such as acoustic shadowing and the enhanced transmission. It can also be useful to evaluate the possibility of aspiration of the calcifies masses by knowing of the contents of the water among them. Unlike the MRI it is useful to get real time informations with low cost in diagnosis and treatment of the soft tissue disease usinf artifacts in sonography.

  • Purpose: The purpose of this study was to identify the relationships between emotional intelligence, organizational citizenship behavior, organizational commitment and organizational performance of clinical nurses in Korea. Methods: The participants were 453 nurses, working in three general hospitals in Seoul, and data were collected from December 15, 2012 to February 2, 2013. Data were analyzed using PASW (SPSS ver. 20.0) and SPSS/WIN 19.0 (SPSS INC, Chicago, IL, USA), and AMOS ver. 20.0. Results: The results were as follows: organizational performance is positively influenced by emotional intelligence. Organizational citizenship behavior is positively influenced by emotional intelligence, organizational commitment is positively influenced by organizational citizenship behavior, and organizational performance is positively influenced by organizational commitment. Conclusion: The results of this study demonstrate and help in understanding the relationship between the research concepts and the direction of nursing organizations. We recommend that various educational programs should be developed to improve clinical nurses' emotional intelligence.

  • This paper introduces the concept of knowledge management(KM) and current KM trend(such as community-of-practice, knowledge ecology, and social network analysis) with some successful KM practices, and discusses a chance to apply KM to defense organizations. Although defense organizations have several unique characteristics which differ from other private organizations such as critical security issues, implementing KM initiatives for them seems essential. Implications and future research directions are also discussed.

  • The focus of this study is to analyze the link between existing knowledge in the organization and NPD performance. After a comprehensive literature review, we identified factors influential in the management of existing knowledge, such as efficiency of information acquisition, shared interpretation, structure of organization. Through an empirical research, we found that existing knowledge was positively associated with the efficiency of information acquisition and shared interpretation. Additionally, a strong relationship was found between information acquisition efficiency and NPD. Shared information, however, was not found to be associated with NPD. This result, make us recognize the necessity to better understand some subprocesses through which existing knowledge affects new product performance.

  • We observed ultra-structure of the tribocytic organ of Firicola seoulensis with transmission electron microscope. Microvilli are observed on the surface of the tribocytic organ. Below the muscle layer, we can find three types of cells. Type I cell has electron lucent cytoplasm with a few granules, while type II cell shows electron dense cytoplasm and the particulate granules. Type III cell's electron dense cytoplasm possesses many granules. Of the above three cells, Type I and II cells are believed as tegumental cells. Type III cells are thought as glandular cells specific to the tribocytic organ. This finding on also explain the secretory function of the tribocytic organ of f seoulensis.

  • The most effective cytokinin source for adventitious shoot regeneration of in vitro grown leaves from 'Gala' apple was BA with the concentration of 4.0 mg/L, while auxin source was IAA, IBA and NAA with the concentration of 0.1 mg/L, respectively. As the result of combinational treatment of BA and NAA, 6.0 or 8.0 mg/L BA with 0.5 mg/L NAA was effective for adventitious shoot regeneration from leaf tissues of 'Gala', 0.1 mg/L NAA + 8.0 mg/L BA and 1.0mg/L NAA + 8.0 mg/L BA for internode, and 0.1 mg/L NAA + 4.0 mg/L BA for petiole.

  • To study the capacity of callus and shoot formation on seedling stage in soybean, excised hypocotyl, epicotyl, shoot tip, cotyledonary node and primary leaf were cultured on artificial media (MS and B$_{5}$ medium) supplemented with several hormones. Regeneration of shoots was fairly successful from shoot tip and cotyledonary node tissues in soybean. These shoots could be rooted in vitro through tissue culture technique and transplanted normally into soil. Hypocotyl and epicotyl tissues formed only callus, of which growth and appearance were different according to the kinds of media and additives. A small number of shoots were formed from primary leaf tissues, but they did not develop further.r.

  • Most human bones of Joseon Dynasty period are so good condition that we can do research in physical anthropology, genetics and chemistry with them. In this study, we analyzed DNA typing using 6 human bones of Joseon dynasty period excavated at Janggi-dong, Gimpo. The DNA typing was mitochondrial DNA haplotype, Y-chromosome haplotype and sex determination. Prior to DNA analysis, we distinguished histological index of 6 human bones. As the result of mitochondrial DNA analysis, most of bones were confirmed as haplogroup G, R11, M7, A5, etc. As the result of sex determination, 4 human bones were female and 2 human bones were male. The male haplogroup was confirmed as haplogroup O by the single nucleotide polymorphism analysis of Y chromosome. For extensive ancient human bone analysis, researchers need to apply a histological index to select ancient human bones and explain a relationship among ancient human bones with various analyses of mitochondrial and nuclear DNA.

  • Endodontic treatment of primary molars is a great challenge to the dentists because of their complex morphology. However, there have been limited controlled in vivo studies about filling materials for primary teeth. Hence, the aim of this study is to evaluate and compare histologic responses of different calcium hydroxide canal filling materials that are used in daily clinical practice. Pulpectomies were performed in 132 teeth of the dogs. The root canals were randomly filled with either $Vitapex^{(R)}$ (n = 44), $Metapex^{(R)}$ (n = 44), or $Metapaste^{(R)}$ (n = 44). After 4 or 13 weeks, respectively after operation, the dogs were sacrificed, and teeth were processed for histologic examinations. Inflammatory reaction was evaluated and scored in a blind manner. The Fisher's exact test and Kruskal-Wallis test were used to compare the tested groups. In 4-week-group, all inflammatory responses were in normal range except for fibrosis. In 13-week-group, increased response to various inflammation reaction was shown compared to the 4-week-group. However, there were no statically significant differences between the tested groups in all inflammatory reaction. Overall, there were no significant differences among three materials in responses of apical tissues and all of them showed favorable tissue responses.
