  • 형식증명승인은 외국 감항당국으로부터 형식증명을 받은 후 국내로 도입되는 항공기, 엔진, 프로펠러에 대한 형식설계 검증을 통해 항공기의 안전성을 확인하는 것을 말한다. 우리나라는 항공안전법 제21조 "형식증명승인"에 따라 국내로 수입되는 항공기에 대한 설계 적합성을 확인하고 있다. 최근 미국, 중국, 싱가포르 등으로 구성된 Validation Principles Working Group은 위험평가 기반의 형식증명승인 모델을 개발하였으며 국제 표준화를 위해 노력하고 있다. 이에 따라, 위험평가기반의 형식증명승인 모델을 분석하고, 우리나라의 형식증명승인 제도의 개선방향을 고찰하였다.

  • 2차원 바코드인 QR코드는 사진, 동영상, 지도, 명함 등 다양한 정보를 더 편리하게 담아낼 수 있다. 현재 스마트 폰의 보급으로 QR코드는 다양한 인쇄 매체에 인쇄하여 연결된 인터넷 정보를 손쉽게 검색하는 수단으로 활용되고 있다. 그러나 QR코드는 정보보안이 용이하지 않아, 결재시스템에 활용하기에는 매우 제한적이다. 본 논문에서는 기존의 QR코드와 컬러 도안을 결합하여 새로운 코드를 설계하여, 제품 인증 시스템이 요구되는 분야에 활용할 수 있는 방안을 제안한다. 제안한 방법은 CMYK 컬러 모델로 인쇄된 정품은 전자기기에서 RGB 컬러 모델로 캡처되며, 이때 컬러의 왜곡이 발생하게 되는데, 이를 컬러 매트릭스를 통해 측정하고, 통계 특성에 기초한 정품 인증시스템을 제안한다. 다양한 종류의 컬러 코드를 통해 본 논문에서 제안한 방법이 제품 인증 시스템에 효과적으로 사용될 수 있음을 보인다.

  • 연구목적: 본 논문은 방사선비상계획구역 내 거주하는 주민의 방사능재난 발생시 대피과정에서 사용할 수 있는 방호제품으로서 마스크를 개발하는 과정에서 KOLAS 인증을 받을 수 있는 방안을 연구하는 것이다. 연구방법: 각종 보고서와 논문, KOLAS 인정기구 및 각종 마스크 홈페이지 자료를 조사하여 연구하였다. 연구결과: 국내 방사능재난방재대책을 수립하여 주민보호조치를 강화하고 있으나 방호제품 보급은 갑상샘방호약품이 유일하다. 방사능재난에 대비하여 마스크와 같은 보조적인 지원용품 보급이 필요하다. 방호마스크를 공인인증할 수 있는 KOLAS 인정 공인기관이 없는 실정이다. 결론: 성능 인증 기준이 있는 마스크의 경우 산업용 방진마스크로 공인시험성적서를 발급받고 인증을 받은 후에 자체 기준으로 일반성적서를 받는 이중 과정을 거쳐서 마스크의 KOLAS 인증이 가능하다.

  • The main goal of this study is to survey the actual condition of farm household adopt traceability of agricultural products and the consumers' recognition of the traceability. Thirty six farm household adopted traceability of agricultural products and one hundred twenty three consumers were surveyed for this study. A total of the cultivated area of surveyed farm household was 39.6ha-owned land(21.2ha) and Rented land(18.4ha)-and the cultivated area of crops with the traceability of agricultural product was 15.7ha, consisting of 39.6% of the whole cultivated area. 22.2% of agricultural traceability products was cultivated bychemical method and 77.8% of the them by environment-friendly agricultural methods-organic cultivation accounts for 2.8%, no-chemicals cultivation 47.2% and low-chemicals cultivation 27.8%. As a result of the consumer survey, 75.6% of respondents recognized agricultural product traceability and only 29.0% of them had experience to purchase traceability products. But 61.0% of surveyed people had intention to purchase traceability products in the future. It was found that consumers wanted to know about production traceability information of farm products in order to identify quality certification including environment-friendly certification, product quality such as taste, weight, grade, and the use of insecticides and fertilizers regarding use frequency and kinds of chemicals.

  • This study was focused on analyzing the impacts of e-commerce on the farmer's management behavior and suggesting alternatives for the development of e-commerce in agricultural industry. For this study, survey was conducted for 24 farmers who sell agricultural products through e-commerce in Chungnam province. The results of study are as follows; First, farmers have changed their management practices in terms of production, marketing and processing by using the information of consumers' preferences while doing e-commerce business. Second, farmers have attempted to differentiate their product through product brand and customer relationship marketing, because they recognized the importance of developing marketing techniques adapted to e-commerce system for more revenues. Third, if quality certification system of agricultural products is introduced under e-commerce, farmers would use it for their environmentally sounded farming because they expect to increase their income. Fourth, 75% of the farmers sold their product at retail price. It means that e-commerce farmers act as a price maker rather than price taker at e-commerce market, who will be encouraged to have larger business size resulting in more added value. Based on the results of study, we suggest that there should be reduction of service charge for credit card, and encouragement of B2B transaction for the economy of scale and introduction of quality certification system so as to establish e-commerce system of agricultural industry as soon as possible.

  • The purpose of this study is to analyze the technical pattern and product characteristics of outdoor sportswear marketed in Northern Europe and North America. Based on the results of this study, we wanted to provide practical data on the characteristics of products with high functionality and fashionability for developing outdoor sportswear. Therefore, in this study, technical pattern, textiles, details, sewing, compatibility with wearable devices, and certification of 33 marketed outdoor sportswear were analyzed. After analyzing various technical patterns, the bent arm pattern using two-piece panel and a raised arm pattern connecting the side seam with the inner seam of the sleeve appeared on the top. Additionally, the patterns of bent legs with darts in the knee, cutting the posterior, and inserting the gusset in the crotch were mainly seen in the bottoms. By analyzing product characteristics, ergonomic pattern design for easy activity and functional materials was used for climate adaptation in extreme outdoor wear. On the other hand, for outdoor wear meant for trekking or hiking, details, such as portability and easy storage, were considered. Eco-friendly materials were used while ensuring light weight and comfort. Furthermore, for convenience of life, safety, and health, wearable devices were integrated into the outdoor sportswear. Eco-friendly green certification of outdoor products was obtained for the labor environment and production process, and relevant information was provided to consumers.

  • Greenhouse gas and energy reduction goal management system is announced to reduce national CO2 emission in 2011. The target business sector of the system has to follow the procedure of the system and get the assessment. The percentage of the national CO2 reduction goad is 30 % compared to the amounts of BAU. In railway business sector, 6 bodies are included in this system so that railway industry cannot stay and sustain its better position any more than other transportation industry. Most of the industry except Railway industry is struggling to develop its product more environmentally friendly and get the 3rd party certification like Eco-labelling and Carbon footprint. To get environmental certification, LCA method has to be applied because life cycle approach is needed to respond current environmental requirement. The purpose of this project is to facilitate railway vehicle manufacturer obtaining the environmental certification termed Korea EPD. By doing so, the environmental performance evaluation tool would be developed and modelled within the LCA framework and therefore applied especially for rail vehicle.

  • Recently, the using of prefabricated temporary equipments is increasing in the industrial field because it can reduce the installation and dismantling period. The various types of prefabricated temporary equipments are manufacturing with various materials in domestic and overseas countries. However, those equipments should win the safety certificate according to the "Governmental Notification about Safety Certification" which regulate the member-based safety certification. It tends to cause over performance of temporary equipments because it couldn't consider structural benefit of the prefabricated products. As the result of this study, it is concluded that the establishment of new safety certification standard for the prefabricated temporary equipments is resonable and the movable scaffold is appropriate for those prefabricated temporary equipment. The movable scaffolds are using as single structure and cannot be expands horizontally. Other types of temporary equipments are using as complex structure which can freely expand horizontally according to the main structure. From the results of the study, the standard of vertical compression performance of prefabricated movable scaffolds should be more than double the performance of single main frame. Other test items of safety certification standard should be fixed when the Notification is amended. The prefabricated temporary equipments which are adopted for the safety standard on assembled structure should be used, moved and kept in assembled state and not separated discretionally. The establishment of new standard for the assembled structure based on this study leads to the development of various types of temporary equipments using structural efficiency of prefabricated structure.
