In Korea, the ITS project has been progressed to improve traffic mobility and safety. Further, it is to relieve traffic jam by supply real time travel information for drivers and to promote traffic convenience and safety. It is important that the traffic information is provided accurately. This study was conducted outlier elimination and missing data adjustment to improve accuracy of raw data. A method for raise reliability of travel time prediction information was presented. We developed Historical Profile model and adjustment formula to reflect quality of interrupted flow. We predicted travel time by developed Historical Profile model and adjustment formula and verified by comparison between developed model and existing model such as Neural Network model and Kalman Filter model. The results of comparative analysis clarified that developed model and Karlman Filter model similarity predicted in general situation but developed model was more accurate than other models in incident situation.

Recently, the transition from conventional analog broadcasting to digital broadcasting has been proceeding as a result of the advance in digital multimedia broadcasting technique. In radio broadcasting, Eureka-147 DAB(Digital Audio Broadcasting) was decided as the standard system of digital radio broadcasting in Korea. In addition to CD quality audio, a variety of data services and excellent performance in mobile reception can be served by DAB, and DAB was evolved into DMB(Digital Multimedia Broadcasting) in Korea for the purpose of emphasizing moving picture multimedia service by DAB. In case of digital broadcasting, it is absolutely essential to measure the BER(Bit Error Rate) in the received signal in order to evaluate the coverage obtained by a transmitter and the quality of the received signal. In this paper, we propose efficient subchannel data structure and BER measurement algorithm. and then verify it by laboratory experiments. With a proposed method, the synchronization for BER measurement is easily obtained and especially the exact results can be obtained by classifying the lost bits which are included in the reception-failed CIFs(Common Interleaved Frame) into errors. This makes the proposed BER measurement system especially appropriate to DMB in which the frequent changes in channel status caused by mobile reception environment exist.

최근 사회기반 시설물들의 대형화, 고밀도화가 됨에 따라 재해 재난대비에 대한 관심 또한 높아지고 있다. 특히, 화재는 우리 주변에서 지속적으로 발생하는 재난이다. 한편, 지진과 같은 경우에는 중소규모가 한반도내에서 빈번하게 발생하고 있지만 직접적으로 피해를 경험 한 적이 없어, 적극적으로 대비해야하는 재해로는 아직 인식하고 있지 못한다고 할 수 있다. 재난, 재해에 대한 연구는 과거의 피해를 기준으로 미래에 대한 대책을 해결책으로 제시하는 방식으로 많은 연구자들에 의해서 지속적으로 이루어지고 있다. 본 연구에서는 우리사회에 발생 가능한 재난에 대해서 서로 다른 인식 수준을 가지고 있는 지진과 화재의 재난에 대한 시민인식차이를 실증적으로 검토하였다. 화재 및 지진에 대한 설문조사를 실시하고 결과 분석을 통해 나타나는 재난시의 인간행동심리를 Facet이론을 이용하여 범위를 선정하고 분석하였다. 분석방법으로는 통합적 분석 방법으로 각 연령대별로 분류하여 분석하였다. 연령대별로 습득한 지식 및 교육환경 배경이 차이가 있을 것이라는 가정 아래 연령대별 분류를 하였다. 설문조사결과를 바탕으로 Facet이론에 근거하여 분석한 결과, 화재발생시의 통합적 분석의 경우는 [MATTER], [SPACE], [ENERGY]등이 다수 나타났고 지진 발생 시에는 통합적으로 [SPACE], [ENERGY]가 다수 나타났다. 따라서, 지진에 대한 국가적으로 교육시스템을 갖추고 개인적인 지진발생시 행동상황을 숙지하고 연습하는 것이 필요한 것으로 나타났다. 결론적으로 지진과 화재시의 인간행동심리를 비교한 결과, 화재는 우리나라에서 가장 빈번하게 발생하는 재해이기 때문에 비교적 국가적으로나 개인적으로 대비를 하고 있다는 것을 실증적으로 나타내었다. 화재로 인한 재난은 국가적으로 끊임없이 교육(인식전환)을 실시하고 있음에도 불구하고 지속적으로 발생하고 있다. 하지만 지진과 비교해 인위적 과실로 인한 재난임에도 불구하고 사전에 화재발생시 대처하는 행동숙지로 인해 많은 인적 및 재산적 피해를 줄일 수 있다. 최근 우리나라는 지진에 대해서는 건축물의 붕괴로 인한 피해방지에 중점을 두고 건축물의 내진성능에 대한 평가가 점진적으로 추진되고 있다. 하지만, 지진발생시 이와 같은 현재 방재정책과 더불어 국민 스스로 지진에 대한 발생가능성 및 예상위험에 대한 인식수준을 향상시킴으로서 국가적 재난을 효과적으로 대처할 필요가 있음을 실증적으로 나타내었다.

출연기관 감사업무 효율화 방안은 네가지 측면에서 정리하여 볼 수 있다. 첫째, 법률적 측면에서 보면 감사원법에서 출연금은 감사대상에 포함되어 있어 출연기관은 감사제도를 운영하게 되어있다. 둘째, 정책적 측면에서 국회에 의한 국정감사는 연 1 회 총 20일간에 걸쳐 수행되므로 시간적 제약과 함께 지속성, 일관성 있는 적절한 감사가 이루어지기 어려운 측면이 있다. 셋째, 행정적 측면에서의 필요성은 일반적으로 이공계 연구개발 업무를 수행하고 있는 과학기술부 산하의 출연연구소는 정부기관이나 지방자치단체 또는 보조금 지원 기관과는 그 성격이 완연히 다른 연구기관임으로 연구생산성 제고에 적합한, 기관 특설에 맞는 자체 규정의 보완이 필요하다. 마지막으로 사회문화적으로 감사업무는 능률우선주의보다는 서류체계 및 규제중심으로 편향되기 쉬운 특성이 있어 이에 대한 개선방안 노력이 매우 중요하다. 출연기관의 감사기능은 내부.외부감사에 의하여 수행되고 있으나, 감사(監査)의 핵심적 기능은 역시 출연기관 자체의 감사(監事)에 의하여 수행되며 성격상 공정성(Fairness), 객관성(Objectivity), 신뢰성(Reliability)의 확보가 필수적이다. 출연기관 감사제도의 개선방향은 합법성, 합목적성을 근거로 기관운영의 효율성을 제고시키는데 초점을 맞춘 감사제도로 개선되어야한다. 감사조직체계의 개선, 전문 교육의 실시, 동일업무의 기준 마련, 상급기관과의 역할분담 정립 등으로 감사업무의 질적수준 및 효율성을 제고해야 한다. 감사평가제도는 그동안 실시된 사항이 없으므로 긍정적인 측면과 부정적인 측면이 공존하므로 평가제도의 도입 및 적용에 대해서는 보다 심층적인 검토가 필요하다. $[$감사조직의 평가요소$]$ ■ 투입요소측면 - 감사인력 - 장비 및 고정자산 - 예산(년도별) - 정보수집관리 - 조직운영방식 -전통 및 관습 - 관계법령, 규정, 감사업무지침 ■ 산출요소측면 - 감사운영 실적 - 감사보고 실적 - 감사제도 개선 및 자체개혁 실적 - 기관운영 효율화 기여도 - 기관의 연구성과 및 업적 향상 기여도 - 경영관리 고도화 기여도 등의 항목설정이 가능 출연기관 감사업무의 효율화 방안으로 감사제도 개선의 기본방향, 감사조직 및 인력운영의 개선, 감사업무 운영체계의 개선 등을 중심으로 발전방향을 제시하였다. 그러나 여기에서 제시된 개선방안들을 추진하기 위해서는 전문인력을 보강하고 상부체계에서의 수용이 요구되므로 출연기관 권역에서만으로의 힘으로는 한계가 있을 것이며 무엇보다도 감사제도 변화의 필요성과 미래지향적인 환경이 조성되어야 할 것이다.

This study was conducted to find ways to expand investment and seek cooperation measure in Cambodia. It is located on the Indochina Peninsula in East Asia, and has historically suffered a lot from social systems and politics. It is a politically constitutional monarchy and shows a neutral tendency in the form of a non-alliance of pro-Westernism. Cambodia recently recorded a high growth rate due to the economic liberalization promoted since the mid-1980s. It is also emerging as the next generation production base in Southeast Asia. The diplomatic relationship, which had been temporarily suspended with Korea, was resumed in 1997. Since then, it has been conducting mutual trade and exchange. Therefore, this study which is as unfamiliar and infrequent looked at Cambodia's economy, trade trends and support plan. In addition, various development possibilities were considered. In particular, in-depth research was conducted on local entry methods and participating projects. First of all, it was devised various ways to expand investment and human exchange, diversify public-private relations, and enter the logistics, distribution, and infrastructure projects directly. As such, this study was developed to serve as a basis for contributing to a part of the research on Cambodian economy and trade in the future.

The number of foreign qualification holders has been on the rise due to the globalization and the development of transportation. As in other developed nations, Korea faces the growing demand for foreign higher education recognition (FHER) since the number of foreign students and migrant workers has reached about one million recently. Unfortunately, there has been no FHER system in Korea so far. In this context, this study has compared the cases of Australia and New Zealand. The results reveal that these two countries are similar in that both of them have developed their own FHER system in order to attract highly qualified foreign workers and students. However, they are different in terms of the implementation of the FHER system and the development of the FHER database. Besides, the cases of both countries shed light on the key issues related to the FHER. Taken together, they provide significant implications for the Korean government which has to develop its own FHER system in the near future.

Recently, China has expanded enormously its economic trade exchange bilaterally with other nations and developed as the second largest aviation market in the world. While open skies bilateral agreements were signed between China and other countries, the agreement processes influenced the aviation market structure and market sharing heavily. This paper analyzed the Chinese aviation market by such three angles as market scale, competitive situation, and market concentration. It is concluded that the Chinese aviation market is the oligopolistic market structure tested by the Herfindahl-Hirschman Index. Finally, suggestions are given to the airlines operating in China such as joining the air alliance, paying attention to a different frequent flyer program (FFP) etc.
