  • This paper is the result of research what im-ply the shaman's costume in Korea "Kut" The implications can be summarized as follows: 1) Shaman's costumes in "Kut" are divided into two parts. Namely the one is the position as a priest and the other is the one as God it-self 2) Also shaman's costume were used to ex-press God's character in the ritual "Jae-Cha" These were based on the costume system by one's social position in the times of the Cho-Sun. 3) The reasons why shaman worn the tra-ditional costume are discussed variously. Among those reasons firstly shaman stands for the symbolic significance of each "Kut" as the agent of God. And secondly shaman wore to symbolize the miraculous virtue of God. symbolize the miraculous virtue of God.

  • This study is intended to identify the factors affecting the successful information warehouse (IW) implementation through the technology acceptance model. As the IW has played an important role with the organizations, it has become a strategic management tool. However, because the building of an IWS requires a great amound of financing and a multi-period, managers should consider identifying the variables as a predictor of IWS success. The related research areas, such as TAM , TRA, and innovation diffusion theory, and previous research associated with the EWS success factors are reviewed in this paper. Based on the hypotheses presented , the study will empirically test the relationships between six external variable-user involvement, computer self-efficacy, OLAP characteristics, problem difficulty , user training and top management support-and system utilization via user's perceptions of ease of use, unusefulness. This study semmes to be a first attempt in this research area, and its results will provide general guidclines for IWS project managers to enhancement the like hood of system succes.

  • the vector, pGUR19, for Rhizobium gene manipulation, was constructed by combining the replication and mobilization function of indigenous multicopy plasmid from Acacia(Robinia pseudoacacia L.) Rhizobia sp86 with E. coli cloning vehicle, pBR322. The vector could be efficiently mobilized by RP4 tra function incorporated into chromosome of E. coli named SM10 and efficiently transferred to various gram negative hosts including Rhizobium and Afrobacterium by transformation. Mobilization frequency of the constructed vector was ranged from $1.2\times 10^{-2}$ (E.coli HB 101) to $4.6\times 10^{-4}$ (A. tumefaciens 15955) and transformation frequency was ranged from $5.4\times 10^{-7}$(E. coli HB101) to $1.2\times 10^{-10}$ (A. tumefaciens 15955). The vector, pGUR19, was stably replicated and maintained in a variety of Rhizobium and Agrobacterium.

  • 지금까지 전력계통에 대한 안정도 해석이 활발하게 논의되고 있다. 과도 안정도 해석의 시모의법에서 보편적으로 사용되고 있는 알고리즘들에서 기존에 사용되어졌던 SI법 중 Trapezoidal법이 알려져 있으나 그 데이터 오차가 많아 신뢰할 수 없기 때문에 거의 사용되지 않고 있는 현실이다. 본 논문에서는 이러한 시영역 모의 방법 중 SI법의 Trapezoidal법이 오차가 많은 단점을 없애기 위해서 전력계통 상태변수의 업데이트를 위한 새로운 알고리즘을 제안하였다. 제안된 알고리즘을 명확한 수학적 이론으로 증명하였으며, 제안된 방법을 전력계통에 적용하여 과도 안정도 해석을 한다.

  • Military technology transition is the process of transition from the science and technology environment to systems to supply effective weapon systems and support systems to the fighters. In case of technology transition decision, immatured technologies result in increasing acquisition cost and delaying schedule toward the objective system. In this paper, we proposed a method to identify and select critical technology elements by integration relations between technologies or components, for supporting technology transition and risk management of military R&D projects.

  • The physico-chemical properties and characteristics after thermal treatment of natural zeolite from Kampo area were studied. The physico-chemical properties of natural zeolite were studied by investigating chemical composition, x-ray diffraction pattern(XRD), scanning electronic microscope(SEM), infrared spec-tra(IR), thermal analysis(TA), and cation exchange capacity(C.E.C.), and the characteristics of natural zeo-lite after thermal treatment from $400^{\circ}C$ to $900^{\circ}C$ were compared with the natural zeolite. This study showed that clinoptilolite was the predominant costituent in natural zeolite, and the natural zeolite contained a little amount of quartz and feldspar as impurities. Zeolite mineral was seen to develop slowly by the natural alternation of volcanic ash considering the almost amorphous crystal structure. The more temperature of ther-mal treatment increased, the more adsorption capacity decreased, considering the fact that the hydroxy peak diminished on infrared spectra, and that cation exchange capacity also decreased distinctly.

  • Electrochemical and spectroelectrochemical studies of cobalt-Schiff (Co-SB) base complexes, Co(salen) [N-N'-bis(salicylaldehyde)-ethylenediimino cobalt(II)] and Co(salophen) [N-N'-bis(salicylaldehyde)-1,2-pheny-lenediimino cobalt(II)], have been c arried out to test them as oxygen reduction catalysts. Both compounds were found to form an adduct with oxygen and exhibit catalytic activities for oxygen reduction. Comparison of spec-tra obtained from electrooxidized complexes with those from Co-SB complexes equilibrated with oxygen in-dicates that the latter are consistent with the postulated complex formed with oxygen occupying the coaxial ligand position, namely, Co(III)-SB·O2 - .The catalysis of oxygen reduction is thus achieved by reducing Co(III) in the oxygen-Co-SB adduct, releasing the oxygen reduction product, e.g., O2 - ., from the Co(II)-SB complex.

  • 본 논문에서는 분산 서비스거부 공격(DDoS)이 발생할 때 네트워크 트래픽의 특성을 분석하기 위해서 트래픽 비율분석법(TRA: Traffic Rate Analysis)을 제안하고 트래픽 비율분석법을 통해서 분석된 다양한 유형의 DDoS 공격의 특성을 기계학습(Machine Learning)을 이용해서 DDoS 공격의 탐지규칙을 생성하고 그 성능을 측정하였다. 트래픽 비율분석법은 감시대상 네트워크 트래픽에서 특정한 유형의 트래픽의 발생비율을 나타내며 TCP flag rate 와 Protocol rate 로 구분된다. 트래픽 비율분석법을 적용한 결과 각각의 DDoS 공격 유형에 따라서 매우 독특한 특성을 가짐을 발견하였다. 그리고, 분석된 데이터를 대상으로 세 개의 기계학습 방법(C4.5, CN2, Na?ve Bayesian Classifier)을 이용해서 DDoS 공격의 탐지규칙을 생성하여 DDoS 공격의 탐지에 적용했다. 실험결과, 본 논문에서 제안된 트래픽 비율분석법과 기계학습을 통한 DDoS 공격의 탐지방법은 매우 높은 수준의 성능을 나타냈다.

  • Organizational culture has been recognized as a determinant of corporate Effectiveness. Cultural components could affect corporate Effectiveness to different extents. However, it seems that none of the previous studies have evaluated and compared these influential extents of cultural components. The current research applies analytic hierarchy processes to assess and rate the significance extents that, cultural components play in resulting in corporate Effectiveness. Then, the current work utilizes regression analyses to re-evaluate the significance extents for the robustness of analytic hierarchy processes. The findings indicate that clan culture is the most vital component in explaining corporate Effectiveness. In contrast, adhocracy culture is the least important component in affecting corporate Effectiveness. Market culture is a cultural component that is ranked the second in determining corporate Effectiveness, and next is hierarchy culture which is the third. The findings are in support of the positive influences of clan, market, and adhocracy cultures on corporate Effectiveness; whereas it found the negative impact of hierarchy culture on corporate Effectiveness.
