The checklist currently used for aviation safety inspection performed by ASIs(Aviation Safety Inspectors) consists of inspection groups and multiple items, it does not have safety attribute and structured hierarchy system which required to efficiently process aviation safety analysis. On this study, categorized the domestic and foreign ASI checklist by safety attribute from ICAO recommended and presented composition of checklist for safety assurance by comparative analysis composition of domestic and foreign ASI checklist.

This paper introduces nine acceptance sampling plans by attribute based on screening (sorting, rectifying). Revised KS standards for single and double acceptance sampling by attribute such as Dodge - Romig : 1998, KSA ISO 2859 - 2 : 2001, 13448 - 1, 2, MIL - STD - 105E : 1989, KSA IEC 60410 and ANSI/ASQ Z1. 4 : 2003 are presented.

In the future, smartphone convergences are not only based on the on/offline integration, but also with the integration between mobile communications and broadcasts. Therefore, there is a need to search for new direction of mobile device that enables variety user applications that are different from the existing size and application issue. The aim of this reserch is to improve user interface of smartphone's functional attribute. The survey results in this paper showed that the most preferable attribute of smartphone among the 8 was the wireless internet 25.3%, followed by messaging 20% and application 19.8%, which totaled to 62.5%. But the samples used were mostly limited to those aged 20 through 30. So the results are not considered as a representative preference of all smartphone users, and should be considered otherwise before materializing them to a product. Therefore, for the more liable results the further research should be conducted to gather data from a variety of users of all ages, and the functional attribute should be analysed through QFD.

본 연구에서는 조건부 선택법을 이용하여 여러 속성들과 다양한 수준으로 구성된 가상의 택배 서비스 프로그램에 대한 소비자의 선택 행동을 체계적으로 분석함으로써 개별 속성들의 수준변화에 따른 소비자들의 평균 지불의사액을 측정함과 동시에 응답자의 성, 연령, 소득 등 사회 경제적 특성에 의한 택배 서비스 선택 결정요인을 분석하였다. 실증분석결과, 공변량을 포함하지 않은 모형을 기준으로 할 때 개별 속성 수준이 1단위 개선될 경우 응답자들의 평균적 지불의사액은 안정성 변수의 경우 2,349.6원으로 가장 크고, 이어서 정확성 변수의 경우 829.3원, 신속성 변수의 경우 588.5원, 마지막으로 친절성 및 사후 서비스 변수의 경우 358.8원으로 분석되었다. 이러한 결과를 토대로 할 때, 응답자들은 택배 서비스 속성들 중 안정성을 가장 중요시하며, 이어서 정확성, 신속성, 친절성 및 사후 서비스 등의 순으로 중요시함을 알 수 있다. 본 연구에서 도출된 택배 서비스의 개별 속성에 대한 정량적 가치들은 향후 바람직한 택배 서비스 가격정책 수립에 있어 유용한 정보를 제공할 것으로 판단된다.

Therefore, there is a need to search for new direction of mobile device that enables variety user applications that are different from the existing size and application issue. The aim of this research is to improve user interface of smartphone's functional attribute. We study on the analysis of smartphone's functional attribute by AHP. The survey results in this paper showed that the most preferable attribute of smartphone among the 8 was the wireless internet 25.3%, followed by messaging 20% and application 19.8%, which totaled to 62.5%.

This study investigated the influence of product attribute on initial trust and purchase intention of sensor-based smart clothing. Questionnaires were administered to 256 university students in Daegu, Korea. The results were as follows: First, there were 5 factor solutions in product attribute of smart clothing; comfortableness, health usefulness, management easiness, safety, and aesthetic appearance. Second, there were significant effects on initial trust in heath usefulness, management easiness and safety. Third, there were significant effects on purchase intention in health usefulness, management easiness and aesthetic appearance. Fourth, there was a significant effect on purchase intention in initial trust.

This paper presents various interval estimation methods of binomial proportion for small n in multi-product small volume production and extremely small ^P like PPM or PPB fraction of defectives. This study classifies interval estimation of binomial proportion into three categories such as exact, approximate, Bayesian methods. These confidence intervals proposed in this paper can be applied to attribute process capability and attribute acceptance sampling plan for PPM or PPB.
