The effective management of knowledge has become one of the critical success factors in current organizations. In spite of the extensive use of Knowledge Management System (KMS), useful information and knowledge resources are still transmitted through personal networks among people in organizations. Thus, social network theory which focuses on social relationships in organization can be a fruitful theoretical resource for enhancing Knowledge Management (KM) performances. In this study, we investigate the effects of intra-team network characteristics (i.e., group density and degree of centralization) and external boundary spanning activities on knowledge management performances of a team. We also acknowledge that all group members do not necessarily agree on the team goal and actively disseminate useful information and knowledge. Drawing on the political perspective on KM which emphasizes the role of trust among group members, we examine the mediating effects of team trust between internal/external network characteristics and KM performances. From the data of 220 teams in financial companies in Korea, we found that: (1) group density had positive effects on KM performances (i.e., knowledge creation, sharing, and use). (2) However, centralization was not significantly associated with KM performances. (3) Team trust was found to be an important factor mediating the relationship between intra-team network characteristics, boundary spanning activities, and KM performances. Based on these results, we discuss and suggest possible implications of the findings when designing and implementing KM practices.

Given the large investment and prevalence of knowledge management (KM) in organizations, it has become important to analyze the effects of KM activities on organizational performances. A theoretical framework is proposed to investigate the impact of KM activities on innovation capabilities in the IT service industry. This study considers KM activities as the major determinant that enhances absorptive capacity. KM activities enhance employees'ability to obtain external knowledge, resulting in increasing intellectual capital. Thus, this study proposes that absorptive capacity plays a mediating role between KM activities and innovation capability. Additionally, this study investigates the key antecedents of KM activities that promote employees' knowledge sharing. Based on prior studies on KM, this study posits KM team activities and top manager support as KM activities. The proposed research model was tested by using survey data collected from 556 employees in the IT service industry. PLS (partial least squares) was employed for the analysis of the data. The findings of this study showed that KM activities and absorptive capabilities play a significant role in enhancing service innovation and process innovation in the IT service industry. The results also shed light on the mediating role of absorptive capacity between KM activities and innovation capability. Moreover, both KM team activities and top manager support serve as the salient antecedents of promoting employees' knowledge sharing.

It is well known in KM (Knowledge Management) literature that a certain amount of knowledge is necessary for KM to contribute corporate performance to some extent. However, It is considerably difficult for a company to amass knowledge due to limited time and lack of understanding from employees. In this respect, DAEWOONG, one of leading pharmaceutical company in korea, shows very special knowledge management activity, SOP(Sucess of project), by which DAEWOONG succeeds in catalyzing the knowledge sharing process among members and cultivating men of ability. Also, DAEWOONG improve working performance at an individual level as well as team level. This case will help understand how important the knowledge management activity is to improve the corporate performance.

It is well known in KM (Knowledge Management) literature that a certain amount of knowledge is necessary for KM to contribute to corporate performance to some extent. However, for a company to amass knowledge is very difficult due to limited time and poor understandings from employees. Especially, it becomes harder in public organization where simulating financial motif among members is constrained. In this respect, KORAIL, one of typical and leading public organizations in Korea, shows very unique example in which KORAIL succeeds in catalyzing the knowledge circulation process among members, string the resulted working knowledge, and then sharing it to improve working performance at an individual level as well as team level. This KORAIL case will help understand how important the knowledge circulation speed is to improving the corporate performance.

지식경영이란 무엇인가? 흩어진 지식을 모으고, 낡은 지식을 새롭게 하고, 모아진 지식을 공유하여 새로운 지식을 창조하는 것이다. 지식경영의 성공적인 추진을 위해 가장 중요한 3요소는 최고경영자의 추진의지, 조직 구성원의 참여를 통한 공감대의 형성, 지식경영추진담당 조직의 지속적인 추진의지와 열정이 조화롭게 상호 보완적으로 작용하여 추진되어야 한다는 것이다. 지식경영 추진에 있어 가장 중요한 것은 기업(기관)의 조직 구성원이 지식경영 참여문화(공감대)를 반드시 형성하지 않으면 지식경영이 성공하기에는 다소 무리라는 것이다. 지식경영을 추진함에 가장 중점적으로 해야 할 일은, 우리 민족의 특성인 구술이나 구전 문화를 기록의 문화로 변화 시킨다는 것이다. 지식경영을 추진하는 가장 큰 목적은 과연 무엇일까? 지식 경영을 통해 조직구성원 및 각개의 조직이 보유한 직접경험지식과 간접경험지식의 공유, 활용, 창조를 통해 지식을 자산화하고, 그 지식자산 가치를 증대 시켜서 21세기 건설 산업의 강자로서 다시 태어날 수 있도록 우리 스스로를 준비하는 것으로 정의하고자 한다.

The magnetic field at the surface of the Sun is concentrated in magnetic features that often have spatial extents of 100 km or less. The study of the fine scale structure of the Sun's magnetic field has been hampered by the limited spatial resolution of the available observations. This has recently changed thanks to various new high-resolution facilities, among them the SUNRISE observatory, built around the largest solar telescope to leave the ground, and containing two science instruments. SUNRISE successfully had its first long-duration science flight on a stratospheric balloon in June 2009 and a host of scientific results have been obtained from the data. After a brief introduction to the Sunrise mission, an overview of selected results obtained so far will be given. A reflight at higher solar activity is currently being prepared.

Objectives : The aim of this study was to examine anti-thrombotic effect of traditional herbal extracts in a rat model of ferric chloride ($FeCl_3$)-induced carotid arterial thrombosis. Methods : Thirty minutes prior to a 35% $FeCl_3$ application, Sprague Dawley(SD) rats were injected with the 10 types of traditional herbal extracts (100mg/kg, intraperitoneal injection), respectively. The effect of these herbal extracts was examined for time to occlusion(TTO) using the Laser doppler flow meter and measured for thrombus weight (TW) in $FeCl_3$-induced thrombosis model. Results : In the TTO, Salvia miltiorrhiza (Sm, $2.30{\pm}0.28$ min, p<0.001) and Santalum album (Sa, $2.19{\pm}0.19$ min, p<0.001) showed significantly delayed TTO more than twice compared with Saline-treated group. Cnidium officinale (Co), Psoralea corylifolia (Pc), Scutellatia baicalensis (Sba), Panax notoginseng (Pn), Angelica tenuissima (At), Scrophularia buergeriana (Sbu), Rhus verniciflua (Rv) and Picrasma quassioides (Pq), except for Rhus verniciflua (Rv) also meaningfully impeded TTO more than one fold. In addition, Salvia miltiorrhiza, Santalum album, Cnidium officinale, Psoralea corylifolia and Scutellatia baicalensis significantly reduced TW more than 10% compared with Saline-treated group. Especially, Salvia miltiorrhiza and Santalum album showed the most excellent anti-thrombotic effect among the 10 herbal extracts tested on the restoration of altered TTO and TW. Conclusions : These results suggest that Sm and Sa extracts have outstanding anti-thrombotic effect in $FeCl_3$-induced thrombosis model and is potentially useful as herbal medicines for the treatment and prevention of thrombosis.

In this study, the distribution, bait preference, hosts, symbionts, habitat status, and cytochrome c oxidase subunit-I sequences of the ant Linepithema humile were analyzed. This species habitat comprised approximately 1.5 km along stone crevices, flower gardens, roadsides, and container yards in the vicinity of Busan station, Korea. Feeding activity of this species was confirmed in 9 species of 7 families of plants. Which was approximately 14% of total flora (63 species of 37 families) in the studied area. Particularly, it was observed that Dendranthema indicum and Camellia japonica were the most frequently visited. Further, we verified that they interacted with four species of aphids. We identified 22 species of ants (17 genera, 4 subfamilies) inhabiting the Busan station area, including L. humile, Tetramorium tsushimae, Nylanderia flavipes and the alien species Paratrechina longicornis. In areas where L. humile was the dominant species, the habitat of local native ants was reduced by approximately 30%. Bait preference was ranked in the following order: jelly, water with glucose (25%), and yogurt, with the highest preference for baits containing sugar and protein. The 630-bp cytochrome c oxidase subunit-I sequences of the local L. humile populations were 99% identical to those of L. humile in the National Center for Biotechnology Information database, and the Argentine ants that invaded Korea had a sequence identical to that of other invasive populations from China, Japan, and New Zealand. As L. humile rapidly increases due to domestic adaptation, continuous monitoring and control strategy for eradication are needed to protect domestic biodiversity.

Objectives : This report describes the diagnostic and therapeutic procedures of Collaborative Practice between Korean Traditional Medicine and Western Medicine for two dementia patients. Furthermore, through these cases, we suggest a model of collaborative practice between Korean traditional medicine and western medicine for the treatment of dementia. Methods : Two patients suffering from several symptoms related to dementia received collaborative practice between Korean traditional medicine and western medicine. Physicians of deparment which paient first visit interviewed patient and patient's guardians, discussed the symptoms and the status of the patient. Since then, the medical team made a differential diagnosis based on the results of brain imaging, hematology, urine test. and apprehended the status of dementia by the neuropsychological test. Korean traditional physicians examined the physical symptoms and identified the pattern of dementia in Korean traditional medicine. Following this, they decided on the method of acupuncture, moxibustion, cupping and herbal treatment. Western physicians decided on the type of medication after consideration of the patient's other medical conditions. Every intervention was decided by both Korean traditional physicians and western physicians after discussion. The medical team provided education on dementia and counseled the guardians. They also wrote the paper for using the long-term care insurance for the aged. Results : Two patients showed no improvement on the neuropsychologic and activity of daily living tests. However, the patients' subjective physical symptoms were improved. The collaborative practice between Korean traditional medicine and western medicine improved the patients' and guardians' satisfaction. Conclusions : Through these cases, we propose a model of collaborative practice between Korean traditional medicine and western medicine for dementia categorized diagnosis-test, treatment, prevention, management. More specifically, we supplement qigong and psychotherapy which was inadequate in these cases.
