In SIR filter, fringing capacitances and discontinuities yield a distorted frequency response from those expected by design formulas, especially in higher frequencies. In this paper, a procedure is presented in order to compensate for fringing capacitances and step impedance discontinuities by EM simulation for a 5th order SIR filter. This method propose the procedure of tuning the coupling and the length of individual resonator by EM simulation. For the filter composed by the tuned resonators, no further tuning is required. The procedure is experimentally justified by comparing the measured data of the fabricated filter with the simulation results.

The objective of this research is to validate the BRQ(Brand Relationship Quality) Construct perceived by fashion product consumers. In order to establish and verify the BRQ scale, qualitative survey and quantitative survey were conducted together. 1592 copies of questionnaire were distributed to women in their 20s to 40s living in Seoul and other metropolitan areas from Dec. 26, 2005 to Jan. 8, 2006, and 723 copies of them were used for statistical data. Samplel(n=482)was used for empirical analysis, and sample2(n=241) was used for cross validity test. The data was analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and Pearson's Correlation Analysis. BRQ emerged from exploratory factor analysis as the hierarchical construct composed of six facets including 'self-connective attachment', 'symbol/mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge'. As the fit of this structural model was not good as a result of Confirmatory Factor Analysis, it was revised to have better fitting. Finally, empirical survey results indicate the hierarchical construct consisting of eight distinct BRQ facets including 'love/commitment', 'self-connection', 'symbol', 'mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge' as best representing the final 39item BRQ Scale. Reliability, construct validity, and cross validity of the construct were verified.

Wireless technology is glowing rapidly in the new millennium period. By this technical progress, new idea which separate CDMA 2000-1x service and existing mobile service by the account appears in interconnection market. Especially fixed operator and mobile operator insist contrary opinions. Account Separation of CDMA 2000-lx service is not studied despite it's importance. This paper deal with this subject and analyse logic of operators opinion. By the result of this paper, CDMA 2000-lx is more a 3rd generation service than a 2.5rd generation service and the current account separation criteria based on using frequency bandwidth is not desirable.

외식산업은 국민경제의 발전에 따른 가처분 소득 증가, 여가시간의 증대, 맞벌이 세대의 증가, 핵가족화 등의 성장원인으로 국민의 의식형태의 변화에 따라 수많은 외국 브랜드의 레스토랑이 국내에 진출하여 경쟁이 심화되어 있다. 외국계 레스토랑의 국내 진출은 의식 서비스 품질의 중요성을 인식시켜주는 계기가 되었으며, 고객만족은 그 어떤 무엇보다도 중요한 기업활동의 목적으로 여기는 계기가 되었다. 이러한 점을 감안하여 본 연구는 패밀리 레스토랑을 이용하는 고객들의 만족영향요인으로서 서비스 품질을 선행요인으로 하여 고객만족과 사후에 전개되는 행동과의 관계를 구조적으로 측정하였다. 그리고, 가장 취약한 점을 찾은 후 그 점을 가장 잘 보완할 수 있고, 고객과의 관계를 더욱 친밀히 할 수 있는 새로운 서비스의 타당성을 측정해 보았다. 새로운 서비스로써 지금까지 각 테이블당의 호스트 개념을 고객관리를 함께 하도록 호스트들에게 더 많은 권한을 이양해 주어, 개개인의 호스트라는 느낌을 가져서 타 패밀리 레스토랑보다 특별한 고객으로 대한다는 것을 느낄 수 있게 한다면 통계적으로 살펴봤던 반응성과 공감성 요인의 취약함을 오히려 강점으로 만들 수 있다는 결론이 도출되었다.

The aim of this study is to present the importance of Risk Management and Risk Classification System in Supply Chain to cope with the rapidly changing distribution environment flexibly through the cooperation between a shipper and a distribution company. First of all, we considered existing studies related to the risks of Supply Chain Risk and analyzed 47 different risk factors by 18 kinds of risk causing factors. Second, we collected opinions of corporation specialist group based on the analyzed risk factors and then classified the risk factors into three categories and ten sub-categories. Third, we conducted a survey targeting shipping companies and distribution companies about classified risk and then verified the validity of Supply Chain Risk Classification using verification techniques such as Confirmatory Factor Analysis, Concentration Validity and Distinction Validity. Finally, we suggest some implications based on the verification results.

In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.
