This study was performed to inquire demand for indroducing certification on contract foodservice management company(CFMC) and review about the system in a related field. The methodology was practiced an in-depth interview for grasping demand on certification of CFMC and composition on an appraiser group. Content analysis was reviewed about the system in a related field. Large enterprises and small and medium-sized enterprises were positive opinion on a certification of CFMC and they suggested that education and research institution, industry, government, association will be included in appraiser group. The review about the system of a related industry was investigated by field such as similar product and service with restaurant industry, similar service with hotel and tourism industry. And similar purpose with a certification of CFMC was put in operation as PQ(pre-qualification) and selecting an adequate corporation in architecture industry. Therefore, a certification of CFMC should be tried to scientific introduction by objective verification.

한국의 농업분야에는 여러 가지 인증제도가 존재한다. 그 예로 유기농산물 인증, GAP인증, KPGI인증, TOP푸르트/TOP라이스 인증 등이 있다. 이러한 인증제도는 소비자에게 안전하고 고품질의 농산물을 보장하기 위해 시행되었다. 하지만 각 인증제도가 명확한 목적을 보유함에도 불구하고 이러한 인증제도들이 소비자에게 관련정보를 수반하는데 성공적이지 못하다는 평가를 받고 있다. 그 이유로는 현존하는 몇몇의 인증제도가 오히려 소비자들을 혼란스럽게 하고 있다는 것이다. 그리고 각각의 인증제도를 별도로 유지하고 홍보하는 것은 더 많은 비용을 발생시킨다. 이 연구에서는 여러 인증제도를 활용하여 이러한 문제를 해결하고자 하는데 그 목적을 두고 있다.

Electrodeless lamp is famous for its long life. But its reliability is dependent not only on electrodes but also on materials and structures. To evaluate end product's reliability, we studied high temperature durability by $60^{\circ}C$, $75^{\circ}C$ and $90^{\circ}C$ temperature tests, and predicted failure times by an exponential model through regression analysis. However, the test showed that temperature does not affect degradation of electrodeless lamps. Their luminous outputs degrade during the early time of the test (till 250 hours) and then converge to a saturation points. Also, '410nm ~ 530nm' spectrum degrades more than other spectra.

This research analyzed about inconsistence and cause of the audit result on national defense quality management system in certification company. Direction of research analyzes corelation with distribution by items at national defense quality management system standard by Investigated number and occurrence of examination report slight and critical incongruity on 2008 and 2009. Study finding slight and critical incongruity happened to first examination average 10.2 items, renewal examination average 7.0 items. By incongruity occurrence appeared high in item that there are a lot of examination item shares of standard requirement, it was studied by correlative thing between the examination with standard. Factor of incongruity occurrence was proved to comprehension insufficiency for quality management system, quality procedure insufficiency, didn't fulfil proceedings, business was unripe. In this papers, we contribute to propose direction for improvement of national defense quality management system comprehensive faculty elevation and national defense quality certification in this treatise.

The Technical Standard Order articles are the parts and appliances for which the civil aviation authority designates as it is necessary to standardize for the expedited certification process and aviation safety. TSO articles were used on the type certified aircraft as replacement parts in the early days of TSO authorization system, but those articles are widely used on the newly developed aircraft as well in these days. In this paper, we compared the differences of the TSO authorization systems between FAA and EASA, and proposed the rulemaking items to improve Korean TSO authorization system and to contribute to growth of aviation industry.

Purpose: In this paper, we propose a test method for evaluating the life time of the inverter which is one of the main internal configuration systems in order to evaluate the life time of the power supply for the vehicle. Methods: The performance and failure criteria required for the development of the accelerated life test method were established and the Taguchi method was used to derive the stress factors affecting performance and reliability. Results: The major stress of the product degradation were considered to be high temperature. Conclusion: The acceleration factor was estimated through a two-level high temperature test and a test methods was designed to guarantee the accelerated life time of the inverter.
