It is hot issue to get the competitiveness of product through reliability-growth as well as availability and safety in almost high-technology industry including military, chemistry, nuclear, telecommunication, transportation service and so on. In advanced countries, worldwide leading companies have tried to improve and develop high-reliability product as well as reliability management system(IEC60300). We investigate reliability certification systems for product and management system. Additionally, we study the feasibility on the adoption of dependability management system(IEC60300) by empirical survey on companies with product-reliability certification(R-mark) in Korea.

Purpose: This study has developed the accelerated lifetime test method for smps for outdoor lighting LED through two factors of temperature and humidity. Methods: Acceleration condition was confirmed for each stress and model, and acceleration life test model was estimated according to acceleration condition. Results: As a result of confirming the accelerated life test model, in the case of humidity, acceleration was established only in the foreign products. Therefore, it is confirmed that the acceleration condition is insufficient. However, the estimated parameters for temperature are relatively constant. It is therefore suitable for power supply acceleration tests for outdoor lighting LEDs. Conclusion: The SMPS acceleration test for outdoor lighting LED can improve the availability of the product by developing an accelerated life test method that guarantees the reliability of the product.

인공위성은 지상 시스템과는 달리 극한 발사환경 및 우주환경에 노출되고, 운용 중 수리가 불가능하며, 임무 실패에 따른 위험비용이 매우 크기 때문에 고신뢰성, 고비용의 부품, 장비 및 시스템을 채택하여 개념설계단계에서부터 신뢰성을 관리한다. 신뢰성 관리의 주요 목적은 설계변경 및 개발 사이클의 반복을 최소화하고, 개발비용을 절감하며, 시스템의 신뢰성을 향상시키기 위한 것으로서, 대부분의 우주시스템 개발 프로젝트에서는 제품보증(Product Assurance) 활동의 일환으로 수행된다. 제품보증 업무는 크게 품질보증, 신뢰성 관리, EEE 부품관리, 재료 및 공정(Material & Process) 관리, 오염관리, 소프트웨어 품질보증 등으로 구분되지만, 포괄적인 의미의 신뢰성 관리 범주에 이를 모두 포함시키기도 한다. 인공 위성의 개발과정에서 기술성능지표 중 하나로서 중점 관리되고 있는 시스템 신뢰성 관리의 세부기법, 프로세스, 개선 필요사항 등에 대하여 살펴보고자 한다.

This study attempted to identify the effects that would be brought about by the value inclination of agricultural and livestock products producers upon the intention to produce environment -friendly products. In this study, We analyzed the data used in Yang et al.(2014) with producers of agricultural and livestock products in Incheon-si and Gyeonggi-do. Total of 149 valid questionnaires were corrected and value inclination as divided into individualism orientation and collectivism orientation, it has been tried to identify whether the intention to produce environment-friendly products would vary with producer's orientation or not. According to the analysis result, individualism, collectivism perceived public certification and shard value were positive effect on production intention of environment-friendly product. This can be said to have been an attempt to establish a more effective and specific strategy through identifying the characteristics of producers that must be considered first of all in the process of establishing policies.

Purpose: The objective of this study is to provide a methodology that can facilitate efficient development of a product portfolio by utilizing Korean Standards(KS) networks. Methods: A case study on a steel manufacturing company is provided. Social network analysis h as been conducted on KS network and KS certification information of the company. Core test standards of a company have been identified. The core standards, then, used to construct a product-standard network of a corresponding industry. Results: As a result of analyzing product-standard networks, a product portfolio of a company has been developed. It has been shown that the candidate product portfolio is a cost-effective alternative in terms of standard maintenance cost. Conclusion: By using social network analysis, standards information can be used to support new product development process.

IT 기술이 발전함에 따라 네트워크를 통해 방대한 양의 정보가 이동하고 있다. 인터넷을 사용하는 사용자들은 올바른 사용으로 유용한 정보를 획득할 수 있으나, 올바르지 않은 사용을 하는 공격자는 악의적인 목적으로 사용하기 위해 타인의 개인 정보를 노출시키고 유포하여 다양한 피해를 발생시키고 있다. 이를 해결하기 위하여 다양한 정보보호제품이 개발되고 있다. 안전한 정보보호제품을 개발하기 위해서는 개발 과정부터 보안이 필요하며, 안전한 제품을 보증하기 위하여 제품 평가 및 보안 모듈에 대한 평가 제도들이 사용되고 있다. 본 논문에서는 정보보호제품이 안전하게 개발될 수 있도록 기존 정보보호제품 인증 제도뿐만 아니라, 정보보호 기능을 제공하지 않는 제품을 개발할 때 시행되고 있는 다양한 인증 제도까지 포함하여 연구함으로써, 더욱 안전하고 견고한 제품 개발 및 보증 방안을 제안한다.

1994년 성수대교 붕괴사고 이후 강구조물의 품질 관리를 위해 철강구조물제작공장 인증제도가 건설기술관리법에 도입되어 법정임의 인증제도로 운영되고 있다. 그러나 콘크리트 부재의 공장 생산 방식인 PC (Precast Concrete)에 대해 국가적인 품질인증 체계는 마련되어 있지 않다. 이에 건축 구조용 PC를 대상으로 적절한 품질인증제도 도입을 위해 북미, 유럽, 일본 등의 PC 품질인증제도를 조사하였다. 미에서 PC 공장인증제도를 운영하고 있는 곳은 PCI, NPCA, CPCI 등이 있다. 유럽에서 PC 제품을 판매하기 위해서는 CPR 305/2011을 따르도록 법으로 정해져 PC 제품을 포함한 모든 건설 제품은 2013년 7월부터 CE 마크를 의무적으로 부착해야 한다. 일본의 경우 토목용 PC 제품은 제품인증인 JIS 마크 인증을 받도록 되어 있고 건축 구조용 PC를 생산하는 공장은 일본 프리패브협회의 심사를 받고 있다. 이런 조사 결과에 근거하여 국내 인증 체계에 부합될 수 있도록 건축 구조용 PC 제품의 인증제도의 도입 방향을 이 논문에 제시하였다.

In recent years, Korean government has focused on improving the environmental impact of products in order to reduce greenhouse gas emissions and to achieve their energy goals. The government has been conducting the following polices such as green procurement inducement and certification system. After carbon labeling was conducted in 2009, among a total of 1,065 items, 97 building materials have been given a certification: finishing materials items have the highest weight (56%). The increase in the certification numbers shows that there has been considerable technical efforts in the building material industry. At the awareness of carbon label and purchase of low carbon product, however, customers are aware of carbon labeling but the purchasing rate of carbon product is low. In this paper, we suggest that low carbon activities must also be considered in order to create client value by adding the concept of ecological efficiency. The objective of this study to measurer the eco-efficiency of carbon labeled building materials on the basis of environmental aspects of the product with the perspective of economy for purchasing the excellent products.

The Product Carbon Footprint Labeling has been run for more than four years by the Ministry of Environment and there are number of products labeled by KEITI(Korea Environmental Industry & Technology Institute), as for declaring products with their carbon emission during life cycle stages. There are several categories for certifying products by the characteristics of usage. Building products which are applied to a building as combined components or elements, are classified as production goods which means that the products are chosen by a business, not by a final consumer. In this paper, current status of PCF labeling has been reviewed focused on building products and the characteristics of carbon emission by a kind of product such as interior products, window products, structural products, system products and others. Until Dec. 2013, 82 products has been labeled and it covers about 53% among labeled product goods by the certification. Among the labeled building products, interior products are main products. From the results of comparison, variations of emission amounts by products have been found and the cause of variation could be explained by the purpose and material properties of products. However, the exact reason for variations cannot be acquired because of lack of information and the short operation period of the certification program. Further studies and more products are needed to be studied and analyzed focused on the emission characteristic by each product and to suggest reduction technologies for sustainable building products.
