  • The engine is the most significant and essential part of the aircraft. As a result, systematical handling in the aircraft development stage is required from engine design to implementation to the full-scale airframe. This survey demonstrates the procedures demanded by the KAS 23 Civil Aircraft to acquire the engine Type Certification and the flight test procedures for ensuring the operational stability. Surveys were conducted on domestic and international aircraft engine certifications, technical regulations and documentations related to the Means of Compliance for flight test development stage. In addition, organized reference items that should be considered for the certification of engine flight test procedures were reviewed based on the KC-100.

  • 90년대 후반기부터 연이어 발생한 씨랜드 화재사고와 인천 인현동 라이브클럽 화재등의 동일한 유형을 가진 화재사건을 계기로 국내 다중이용업소의 실내장식재 및 장식물품에 사용하는 재료가 화재시 인명참사에 미치는 영향이 크다는 점이 발견되었다. 따라서 국내다중이용업소를 중심으로 실내장식재 및 장식물품의 사용과 관련한 화재안전규정 및 기준을 조사한 후에 유럽·미국 등의 선진국의 관련 규정을 조사 비교하여 그 문제점을 세부적으로 발췌하여 규제방향 및 규제기준의 상이점을 분석하여 대형인명참사를 초래하는 근본적인 원인을 찾아내었다. 고찰된 원인을 근간으로 실내장식재 및 장식물품에 사용하는 재료가 선진국 수준의 방재성능을 가질수 있도록 규제방향을 제시하고 제시된 규제방향을 뒷받침할 수 있는 효과적이고 검증된 시험방법을 연구제시하였다. 최종적으로 향후 발생가능한 대형인명참사를 효과적으로 방지하기 위해 다중이용업소를 중심으로 방화 및 방염제도의 효과적인 수립디 되도록 실내장식재 및 장식물품에 대한 세부규제안을 기술하여 방화 및 방염제도의 세부규안을 제시하였다.

  • This study was aimed at finding out the preferences and satisfaction levels regarding the type of fashion retailer's sales promotion based on consumers' empirical characteristics. A total of 223 questionnaires were used for the survey of this study. The methods of this study were descriptive analysis, factor analysis, reliability tests, one-way ANOVA, $t$-tests and ${\chi}^2$-test. The consumer groups were divided by habitual experience and self-evaluated knowledge relate to apparel product. The results of this study showed that consumers have different preferences and post-utilization satisfaction regarding the type of sales promotion offered by fashion retailers. Consumers with more experiences in apparel product and with higher self-evaluated knowledge were more active in utilizing the benefits offered through the value-added type of sales promotions, such as the gift certificate or coupon. Consumers with more experience in apparel product also showed higher satisfaction with both the utilitarian and hedonic types of sales promotions, such as gift certificate offer, special price, price discount event, and coupon or courtesy card offer. Furthermore, consumers with higher self-evaluated knowledge showed higher satisfaction with the utilitarian types of sales promotion, such as gift certificate offer and regular sale. Therefore, by identifying the accurate understanding of consumers'empirical characteristics, an enterprise might be able to satisfy consumer by offering more appropriate and subdivided types of sales promotion.

  • The purpose of this study was to test whether sales promotions of strategic alliances affected brand switching intention and brand loyalty in family restaurants. The types of sales promotions included monetary benefits/non-monetary benefits, and immediate benefit (benefits immediately after consumers agreed to accept promotion)/delayed benefits (benefits received at a later time). For this purpose, a questionnaire survey was completed by 355 customers of family restaurants in Daegu between December 15, of 2009 and January 31, 2010. The study-findings indicated that (1) monetary benefits (application opportunity for gift certificate benefits and price discount benefits) were found to affect brand switching intention and brand loyalty; (2) brand switching intention was partly affected by non-monetary benefits (mileages accumulations benefits, presents benefits, and samples benefits), and (3) brand loyalty was partly influenced by non-monetary benefits (mileages accumulations benefits, presents benefits and electronic newsletter benefits). This study also found that (1) brand switching intention and brand loyalty were partly affected by immediate benefits (sample benefits, presents benefits, and price discount benefits; (2) brand switching intention was partly influenced by delayed benefits (application opportunity for gift certificate benefits and mileages accumulations benefits), and (3) brand loyalty was affected by delayed benefits (application opportunity for gift certificate benefits, mileages accumulations benefits, and electronic newsletter benefits). Based on these findings, family restaurants should use sales promotions as a tool for decreasing brand switching intention and increasing brand loyalty.

  • 유럽항공안전청에서는 항공기 엔진의 형식증명을 위한 감항기준으로 CS-E (Certification Specification-Engine)를 적용하고 있다. 본 감항기준에 따라 형식증명을 받기 위한 입증 항목 중에 하나는 엔진제작사(형식증명소지자)가 창정비 주기 내에 엔진의 감항성을 유지할 수 있음을 입증하는 것이다. 이에 대한 입증방법으로 엔진의 창정비 주기에서 엔진 임무 거동을 가속하여 시험할 수 있는 가속임무시험이 가장 많이 사용된다. 국내 소형민수헬기 프로그램의 일환으로 개발되는 엔진은 유럽항공안전청의 형식증명 획득을 목표로 국제 공동 개발 중에 있다. 본 연구에서는 이 엔진의 형식증명을 위해 국외 원제작사와 협력 하에 수행되는 가속임무시험에 대한 시험절차를 수립하고, 감항기준 CS-E의 해당 요건과 개발 대상 엔진의 설계 및 운용 특성을 고려한 가속임무시험 사이클을 정립하였다.

  • Adhesive bonding is becoming one of the popular joining techniques in metal industries, since it has some advantages over other techniques such as welding and diffusion bonding, e.g., any dissimilar metals are easily adhesive-bonded together. In this study, the experiments were carried out in order to provide the statistical data with strength evaluation methods: tension, shear and four-point bending tests for thermoplastic epoxy resin based adhesive-bonded metal joints. We should certificate on the probability of the adhesive strength that has the tendency of brittle fracture, the adhesive bonding strength between metals with thermoplastic adhesive has the best probability at four-point bending test. The strength testing method that has higher probability is four-point bending test, shear test and tensile test in order.

  • This experiment extracted the natural green-tea using ethanol and obtained the refined oil component after filterated green-tea extract. This study tested the antimicrobial effect as characteristics experiment, and analyzed refined oil component with pH-meter and GC/MS. In the result of this experiment, it obtained the next conclusions. In the first result of extraction experiment, it could know that extraction ratio of refined oil component appeared about 9.0%. In the second result of characteristics experiment, it could certificate that in case of increasing the refined oil component in concentration of 100ppm and above, and according to passage of cultivation time, the number of S-aureus and E-coli in microbe decreased less and less. But in case of blank test not adding the refined oil component, the number of microbe increased more and more. In these phenomena, it could certificate that refined oil component of green-tea appeared antimicrobial effect against microbe. In the third result of instrumental analysis, refined oil component of green-tea appeared about 7.6 in 1% distilled water solution with pH-meter, and the aromatic components of benzene, bonyl acetate, campene, ${\alpha},{\beta},{\gamma}$-pinnene etcs from refined oil component of green-tea was detected with GC/MS.

  • In the paper, the actual situation of Korean organic agriculture and its development history regards to basic skills of organic farming were reported. And an education for organic farming in the universities with schools of agriculture in European countries was also reported to deliver the information on the course of organic agriculture for Korean Universities facing the problem which have a lower admission competition than previous Year. The examination for organic engineer certificate which was introduced in 2001 and the proposed government research institute, so called "Research Center of Organic Agriculture" were also shortly discussed. In the conclusion, \circled1 the establishment of "research Center of Organic Agriculture" which should by attached RDA for the systematic approach of research for organic agriculture and the test of agricultural materials using for organic farming, \circled2 department of organic agriculture in the Universities with schools of agriculture to offer next generation an opportunity to learn an organic farming parallel to conventional farming, \circled3certification body system by third party, and \circled4 full support by Korean government and scientist society for "Asian Research Network of Organic Agriculture (ARNOA)" headquartered in Korea as international research organization were strongly suggested.
