This study empirically investigated the effects of both organizational culture(i.e., innovative, supportive and bureaucratic) and information technology(IT) infrastructure(i.e., knowledge storage, transfer and search IT) on the knowledge management(KM) activities(i.e., knowledge creation, sharing and application) in Korean manufacturing firms. We also partially demonstrated the impact of KM activities on the KM performance(i.e., KM satisfaction) of a firm. Through multiple regression analyses, it was found that innovative and supportive culture, and IT infrastructure have a positive impact on the activation of KM activities. The results of this study also showed that the innovative and supportive culture positively influence the adoption of IT infrastructure, and through the construction of IT, they have an indirect effect on KM activities. With a structural equation modeling technique, the causal relationships among organizational culture, IT infrastructure, knowledge management activities, and KM performance were confirmed. Hence, it is concluded that culture and IT infrastructure have direct effects on KM activities, and culture also indirectly influences KM activities through the adoption of IT infrastructure.

The venture firms originating from the government-financed research institutes of Taeduk Science Town play a dominant role in Taejon. Those venture fm have the following characteristics. First, they are innovative in the growth stage, although not so innovative in the beginning stage. Second, they still largely depend on the domestic market because of their import-substitution strategy. Third, they mostly lack administrative capabilities. Finally, the infrastructure of venture firms is not good in spite of many supporting government policies. The efficient management of the existing business incubators, the establishment of special venture capital, and continuous supports by the incubating organizations should be warranted to encourage the spin-offs from the government- financed research institutes.

This study aims to explore innovative measures for community policing activities of the Korean police in the context of the newly implemented autonomous police system and the increasing demand for community-oriented policing. By conducting an in-depth analysis of advanced community policing practices in the United States, Japan, and the United Kingdom, this research identifies key characteristics such as resident participation, communication, scientific crime analysis, and customized policing services. The study reveals the need for the Korean police to establish a collaborative governance system that actively involves residents, strengthen scientific policing capabilities utilizing advanced technologies, and provide policing services tailored to local characteristics. Organizational and personnel management reforms, including the substantiation of the local police officer system and the establishment of an institutional foundation for resident participation, are proposed. Furthermore, this study emphasizes the importance of developing a creative community policing model suitable for the Korean context, rather than directly transplanting overseas practices. Continuous research and efforts to build a new policing paradigm that reflects the changing social environment and policing demands are suggested. Ultimately, the success of community policing lies in the active participation and cooperation of all members of society, including the police, government, local communities, and residents.

한약재의 방사선 조사여부를 확인하기 위해 도라지와 오가피에 $0{\sim}10\;kGy$의 감마선을 조사하고 PSL, TL 및 ERS 특성을 비교 검토하였다. PSL을 측정한 결과 비 조사된 한약재에서 한계치($T_1$)인 700보다 낮은 photon count 값을 보이면서 negative로 판정되었고, 0.15 kGy 이상 조사구는 한계치($T_2$)인 5,000보다 높은 photon count 값을 나타내면서 positive로 표시되어 방사선 조사된 것을 확인할 수 있었다. 또한 시료로부터 mineral을 분리하여 TL의 glow curve와 TL ratio($TL_1/TL_2$)를 확인하였다. 방사선 조사가 되지 않은 도라지와 오가피는 TL ratio가 0.007 이하의 값을 나타내었으며, 조사구(1.0 kGy 이상)에서는 0.314 이상의 TL ratio를 나타내었다. 도라지와 오가피는 본 연구에서 설정한 TL ratio의 한계치 0.1보다 높은 수치를 나타내어 방사선 조사여부 확인이 가능하였다. ESR 측정을 통한 방사선 조사 한약재 검지에서는 cellulose 라디칼에서 유래된 특이한 라디칼 신호를 보여주었고, 이는 도라지 시료에서 더욱 뚜렷하게 확인할 수 있었다. 이상의 결과에서 PSL, TL 및 ESR 분석은 도라지와 오가피의 방사선 조사 여부 확인에 적합한 방법임을 확인할 수 있었다

Dual-cooled annular fuel allows a significant increase in power density while maintaining or improving safety margins. However, the dual-cooled design brings much higher Zircaloy charge in reactor core, which could cause a great threaten of hydrogen explosion during severe accidents. Hence, an innovative fuel combined dual-cooled annular geometry and SiC cladding was proposed for the first time in this study. Capabilities of fuel design and behavior simulation were developed for this new fuel by the upgrade of FROBA-ANNULAR code. Considering characteristics of both SiC cladding and dual-cooled annular geometry, the basic fuel design was proposed and preliminary proved to be feasible. After that, a design optimization study was conducted, and the optimal values of as-fabricated plenum pressure and gas gap sizes were obtained. Finally, the performance simulation of the new fuel was carried out with the full consideration of realistic operation conditions. Results indicate that in addition to possessing advantages of both dual-cooled annular fuel and accident tolerant cladding at the same time, this innovative fuel could overcome the brittle failure issue of SiC induced by pellet-cladding interaction.
