  • 선진국에서 1982년 제정된 비핵무기 위험성 평가시험(MIL-STD-2105(NAVY) 이후에 2011년 4월에 개정된 MIL-STD-2105D의 로켓 모타의 둔감화를 위한 추진기관 둔감 시험 규정과 각 둔감시험별 통과기준에 대하여 정리하였다. 추진기관의 시험평가에 대한 연구를 통하여 국내에서는 세계적 수준의 추진기관 둔감시험 기법은 정립하였으나 국내의 추진기관 둔감시험 데이터베이스가 부족한 관계로 반응등급결정을 위한 각 시험별 통과기준이 정립이 되어 있지 않은 실정이다. 따라서 본 연구에서는 개정된 둔감시험방법과 각 시험별 통과기준을 조사 분석하여 국내의 추진기관 둔감화 개발방향을 제시하였다.

  • Bioenergy is classified to one of the renewable energy resources such as solar, wind, hydro and tidal energies. It should be noted that all the renewable energies contribute to the reduction of greenhouse gases emission. In some cases, energy from wastes was also categorized as a renewable energy in our country even though it has only negligible effect on the emission reduction. In this paper, we tried to identify the bioenergy in order to follow the global indices of the renewable energy. The indices evaluated here were whether a resource is renewable, biogenic, biodegradable, combustible and organic. Biogenic and combustible were selected as the indices to identify the bioenergy. It was also suggested that combustible as an index can be exchangeable to organic.

  • 3차원 지상레이저스캐너는 짧은 시간에 대상물의 수많은 위치에 대한 고정도의 3차원 좌표를 얻을 수 있는 장비로서 측지분야를 포함하여 토목공학, 고고학 및 건축, 그리고 응급서비스 및 국방 등 다양한 분야에서 널리 응용되고 있다. 그러나 국내에서 이용되는 지상레이저스캐너 장비는 대부분 외국에서 수입되고 있으며, 현재 측량장비로서 공인되지 않은 상태이다. 따라서 지상레이저스캐너를 다양한 분야에서 활용하기 위해서는 장비 검정과 성능평가를 위한 실외 표준 테스트베드가 필요하다. 본 연구에서는 지상레이저스캐너의 테스트베드 구축과 관련하여 국외 사례를 고찰하여 이를 통해 국내 테스트베드 구축 방안을 제시하고자 한다.

  • Recently the substation automation is actively researched at each country. Since the substation automation is an integrated system that consist of electrical, electronic and computer technologies, performance evaluation is very important to inspect the developed system's applicable possibility for real power system. Most studies are verified using computer simulation, because it is hard to apply them to real power systems. Therefore development of a substation simulator is necessary for the performance evaluation of many application systems such as operator aid system. This paper introduces a substation simulator. An intelligent fault diagnosis and restorative control expert system is also introduced UDP/IP is applied as a protocol for data transport between expert system and SC(station computer). As to the Graphic User Interface, C++ Language and Visual Basic is used in the Windows NT operating system together with four Pentium II systems.

  • Purpose - Our study aims to analyze and assess aeronautics transport, to bring comprehensive insight about the existing potential in the new member states, candidate countries, potential candidate countries, and associated states. Methodology - The evaluation was carried out by applying qualitative methodology to the research results and on existing capabilities, to assess the overall research capability in the aeronautics transport mode of each country and region, in the European context. Results - Overall, countries with the strongest potential are the Czech Republic, Poland, Hungary, and Romania. The aeronautics research potential was evaluated as weak in as many as 11 countries, with Estonia, Bosnia-Herzegovina, Macedonia, Montenegro, Albania, and Moldova being evaluated as weak in all categories, and Latvia, Croatia, and Serbia being evaluated as weak overall but having at least one category evaluated as medium. Conclusion - Based on the research findings, there are recommendations regarding both the research policy and research activities related to the aeronautics transport mode. The findings contribute to the further development of EU aeronautics research and the aviation industry.

  • Customer satisfaction is becoming an increasingly salient topic in many firms and in academic research. One main rationale behind this interest is that customer satisfaction is believed to be associated with fruitful customer re-visit from the firm's point of view. Some country already had index models which can measure the degree of customer satisfaction. But, such models are ordinary models which used generally the scope of nation-wide industry. Therefore, we needs some modifications to measure customer satisfaction for specific product & service and to provide the valuable feedback to specific firms. In this perspectives, this study will evaluate the customer satisfaction index about automobile company and analyze it's result for valuable feedback. This study will present a model for an integrated customer satisfaction evaluation system which used structural equation modeling. Through this study, we anticipate that it will offer the measuring method about customer satisfaction and some guideline for product design process.

  • Leucas aspera Link. (Lamiaceae) is an important medicinal plant in indigenous systems of medicine in India and commonly known as 'Thumbai'. It has various ethnomedicinal values as various traditional communities find diverse medicinal properties. It is used as antipyretic, stimulant, expectorant and diaphoretic drug. The present communication deals with the detailed pharmacognostical evaluation of whole plant of L. aspera collected from five different geographical zones of the country-Uttar Pradesh, Orissa, Karnataka, West Bengal and Gujarat. The botanical characters and TLC fingerprint profile of all the samples were quite similar but some variations were observed in physicochemical parameters. However, some microscopical characters and TLC profile can be used as diagnostic characters for identification of L. aspera, for example amphistomachic leaves and two types of trichomes-abundant, non glandular, uniseriate, 1-3 celled and few glandular, 2-5 celled stalk with rounded tip. Presence of some components at $R_fs-0.56$, 0.65 and 0.76 under UV 366 and at $R_fs-0.31$, 0.43, 0.60, 0.76 and 0.82 under visible light after derivetization in TLC profile may also be used as diagnostic character.

  • In India, Gymnema sylvestre due to the unique property of the plant to antagonize the sweet taste is known as 'Gur-mar'. It has several ethnomedicinal values as various tribals/traditional communities and rural peoples of India find diverse medicinal uses viz. antidiabetic, stomachic, diuretic, and is useful in cough and throat troubles. Besides, it has strong effect on reducing blood sugar. The present communication deals with the detailed pharmacognostical evaluation of the aerial parts of G. sylvestre collected from three places of the country-Varanasi (U.P), Panchmarhi (M.P), Salem (Tami Nadu) and commercial sample procured from local market. The botanical and physico-chemical parameters of all the samples were quite similar though little variations were observed in foaming index, alcohol and water soluble extractives of local sample. The microscopic characteristics of the drug are horse shoe shaped petiole with 3 amphicribal vascular bundles, sieve tubes well developed; anomocytic stomata only on the abaxial surface of the leaf, the fan shaped amphicribal vascular bundle, presence of intraxylary phloem. The TLC fingerprint profile of all the samples was more or less similar only the quantity of some of the compounds varied.

  • With lower quality and three to four times higher price than those of imported malting barley, the competitiveness of domestic malting barley is decreasing. Although the causes can be found in that the domestic environments are much unfavorable to cultivate the malting barley compared with those of USA or Canada, it is mainly reasoned from poorer developments in variety of high quality malting barley as well as in cultivation technology. For assuring the competitiveness of domestic malting barley, therefore, not only the development of high quality malting barley suitable to the climatic environment of this country but also the political supports of the government are required. Also, in addition to the breeding of the good quality malting barley haying higher germinative energy, and heavier and larger kernels of good plumpness as well as lower protein content, the modification of quality inspection standards from the system relying only on the visual characteristics such as kernel size distribution rate, shrimped kernel rate, foreign materials and so on, to such system as those of developed countries haying quality criteria such as protein content for inspection is absolutely required for the quality improvement of domestic malting barley.
