Design and microwave absorbing properties of ferrite plate are investigated for the application to the radiowave absorbers used in anechoic chamber. The required frequency-dependence of complex permeability is determined on the basis of wave-impedance-matching relationship. The plate thickness and matchingfrequency are determined from the complex permeability and dielectric constant, and then compared with the directly measured reflection loss. A systematic variation of material constants and their influence on the microwave absorbing properties are demonstrated.

주택경기 침체와 글로벌 금융위기 등의 영향으로 2008년부터 본격화된 국내 건설경기 침체가 최근까지 이어지면서 건설업계의 경영난이 가중되고 있다. 2012년 건설수주는 불변금액 기준으로 10년 전 수준까지 떨어졌으며 건설투자는 최근 3년간 감소세가 지속되면서 역대 최장기간 감소세를 기록하고 있다. 이처럼 건설경기침체가 장기화되면서 건설투자 감소에 따른 경제성장률 하락, 취업자 감소, 금융부실 확대 등 거시경제 전반에 대한 우려가 확산되고 있다. 여기서는 우리금융경영연구소 허문종 수석연구원의 '건설경기 침체 현황과 거시경제 영향 점검' 보고서를 통해 국내 건설경기의 현황과 건설경기 침체가 가져올 파급효과에 대해 분석하고 분위기 반등을 위한 방안을 검토해본다.

정부는 현재 직면한 교통문제 해결의 필요성을 인식한 후 1993년부터 대통령 직속 SOC 투자기획단에서 ITS 도입문제를 검토하기 시작하여 1997년 「국가 ITS 기본계획」을 수립히였다. 이를 토대로 정부 및 산·학·연등이 능동적으로 참여하여 ITS 사업이 추진되어 왔다. 그러나 1998년 외환위기에 직면하면서 ITS 사업에 대한 투자 감소등의 환경변화와 동시에 ITS 전문가들은 공급자 중심에서 최종 사용자 중심의 기본계획의 필요성을 제기하면서 ITS 기본계획 개정 필요성이 제기되어 더 현실적이고 융통성이 있는 기본계획을 수립하게 되었다. 이러한 배경을 기본으로 본 논문은 개정된 국가 ITS 기본계획의 내용 즉, 제공서비스, 단계별 구축계획, 단계별 예산 등을 살펴본다.

"시대적 흐름에 맞게 환경분야관련 투자를 적극적으로 검토하고 있으며 현재 해외친출을 위한 기반을 모색하고 있습니다. 특히 유니온 자체 브랜드로 해외시장을 진출하는 것 보다는 글로벌 건설사들과 협력하여 해외프로젝트에 적극 참여하고 있습니다." (주)유니온의 강병호 대표는 기업의 적극 투자와 해외시장 개척이 환경산업의 발전을 기대할 수 있다고 강조했다. (주)유니온은 1964년 백시멘트 생산을 시작으로 희소 광산물을 개발해 오다 1988년부터 환경사업에 진출했다. 다음은 유니온의 강병호 대표와의 인터뷰 내용이다.

This study analyzed the financial information between 2011 and 2014 comparing management performance and utilization of capital and human resources between private non-profit general hospitals and regional public hospitals operated as general hospitals. The purpose of this study was to enhance the productivity for financial independence of regional public hospitals. Comparison analysis variables were value added to the total assets, value added to the productive activity tangible fixed assets, value added to personnel expenses, ratio of value added, and operating margin to revenues. According to the analysis results, regional public hospitals showed lower investment efficiency indicator and higher ratio of value added, as well as significantly lower operating margin-to-revenues compared with private non-profit general hospitals. Moreover, the effect of investment efficiency indicators on operating margin-to-revenues was value added to the productive activity of tangible fixed assets and value added to personnel expenses in regional public hospitals; the value added to personnel expenses in private non-profit general hospitals had a significant effect on the operating margin-to-revenues, the effect of value added to personnel expenses was the greatest. Therefore, it is necessary to asset utilization to the revenue and propriety of human resources to personnel expenses in regional public hospitals.

Even though there are growing numbers of IT utilization in many organizations, they are required to use only constrained amount of resources due to the decrease in IT Investment, following economic recession. Besides, the CEOs in those organizations are required to assess how IT Investment, which has been gradually increased during the industrial growth, affects their organizational performances. Thus, they began to enforce IT governance so as to measure IT efficiency and minimize business risks. As a result, they improved the decision making process of IT Investment, enforced IT value assessment, and established the IT Investment-performance evaluation process as well. In this article, I aimed to make it clear how IT Investment affects the IT Performance by analyzing the effects of the factors constituting the IT Investment managing system and the Process Maturity on the User Satisfaction. This analysis can suggest a practical IT Investment-performance model, which can increase organizational performances.

According to EMEP/EEA Emission Inventory Guidebook, the emissions produced by vehicle in cold start phase should be calculated differently compared to hot start phase. In this study, considering this driving cycle, more appropriate procedures for estimating Environmental Benefits was suggested. Using Tier 3 standard, all links within the impact area were included in estimating emissions. Traffic volume and travel distance were analyzed using EMME/3 software. For application of the procedures in this study, the case study was carried out with real transportation project. As a result, the Environment-Benefits increased by 30%. If the methodology suggested in this study is applied to feasibility study it will help to activate the investment of the environment-friendly modes like railway in the future.

In this study, we examined distribution channel relationship by using the idea of Cheong, which is a unique feeling an positive role in Korean society. Companies make great efforts to maintain long-term relationship with buyers. Understanding distinctive relationship system of each culture should precede these efforts to bring effective results. So we considered how Cheong, a meaningful factor in Korean distribution channel, affects relationship quality and performance. As a result of research analysis from 272 survey questionnaires of retailers, engaging in Crops Protected Material industry in Korea, supplier's idiosyncratic investment, retailer's Cheong, and dependence of retailers on suppliers have positive effects on relationship quality. Supplier's idiosyncratic investment and cognitive factors have the highest influence and Cheong, an emotional factor, follows. Dependence, a motivational factor has the least influence. We confirmed that retailer's cooperation and long-term orientation are directly influenced by retailer's commitment. Active cooperation of the retailer, a partner of a distribution channel, is regarded as an essential factor for supplier's effective business. Retailer's commitment increased that cooperation. Retailer's trust and commitment also decreased relationship conflicts. The results of this study imply that companies should increase idiosyncratic investment to improve relationship quality. But increasing idiosyncratic investment is limited because it requires monetary investment. Therefore companies need to recognize the importance of Cheong, revealed as a new factor, improving relationship quality and to make the best use of it. In this study, we contributed theoretically by examining the role of Cheong, and introducing its distribution discipline. We also make practical suggestions about supplier's relationship management.
