PURPOSES : This study is to develop an comprehensive validation methodology for autonomous mobility-on-demand system with level 4 automated driving system. METHODS : The proposed method includes the quantitative techniques for validating both automated driving system and center system using each optimal indicators. In addition, a novel method for validating the whole system applying multi-criteria decision methodology is suggested. RESULTS : The relative weights for the vehicle system was higher than the center systems. Moreover, the relative weights of failure rate for validating the vehicle system was the highest, in addition to, a relative weight for accuracy of dynamic routing algorithm within center system was the highest. CONCLUSIONS : The proposed methodology will be applicable to validate the autonomous mobility on demand system quantitatively considering the relative weights for each systems.

In this study, we have defined measurement and verification methods and procedures to assess the energy use on the utility system of building. Time series data conversion methods and algorithms have been proposed in performance evaluation options. To verify the feasibility of the method, the energy consumption of the refrigerator, which was an energy utility, was measured and analyzed. we present an algorithm based on the annual base conversion and analyze it based on actual data. As a result, a k-means clustering moving average method was defined for the performance calculation option A, and the use time correction coefficient method was proposed. The validity of this method was verified through the verification.

국가차원의 슈퍼컴퓨팅 성능수요 예측은 슈퍼컴퓨터를 활용하는 계산과학분야 의 연구자나 연구개발 인프라를 구축⋅운영하고 있는 전문기관, 과학기술 인프라구축을 주도 할 정부기관에 있어서 매우 중요한 정보이다. 본 연구는 그동안 진행되었던 슈퍼컴퓨터 성능관련 예측활동 분석을 통해 과학기술 역량 에 영향을 미치는 요인들을 도출하고 이를 슈퍼컴퓨터 기술진보 추세에 적용한 복합 예측모 형을 제안하였다. 횡단면분석에서는 슈퍼컴퓨팅 성능에 영향을 미칠 것으로 판단되는 GDP, GERD, 연구원수, SCI논문수를 고려한 다중회귀분석을 수행하였다. 그리고 횡단면분석 결과 에 Top500 자료의 성능(Rmax)값을 이용한 시계열분석을 통해 도출된 기간별 기술진보율을 곱하여 슈퍼컴퓨터의 성능을 예측하였다. 제안된 예측모형을 바탕으로 세계 슈퍼컴퓨터 500위의 시계열자료를 이용하여 한국이 2016년에 보유해야 할 슈퍼컴퓨터 성능규모를 예측하였다. 횡단면분석과 기술진보율을 적 용하여 2016년 한국의 슈퍼컴퓨팅 성능수요를 예측해본 결과 현재의 추세를 이용할 경우 15～30PF 정도, 목표 국가수준의 추세를 이용할 때 20～40PF 정도의 컴퓨팅 역량이 필요할 것으로 예측되었다. 이 결과는 단순 회귀분석을 적용한 결과인 9.6PF와 횡단면분석을 적용 한 결과인 2.5PF와 큰 차이를 나타내었다.

This paper studies the effect of information quality level and customer demand on performance measures in a supply chain. The information quality level compares 2 types, the information levels of a customer demand and a lead time. The customer demand proc

This study diagnosed difference of preference about demand performance with design of men's suit according to demographic characteristic and figured out Needs of adult man consumers for men's suit. This study is survey research. In order to collect data, a questionnaire was used. To analyze the collected data, fact analysis, χ2 test, ANOVA, Duncan's multiple comparisons and the rest were carried out with using SPSS 14.0. Result of this study could get as following. According to silhouette and color, there was difference to age, attainments in scholarship and preference according to job. Also young people preferred fitted-silhouette and in occasion of color, all of them preferred best black. It was no difference according to demographic characteristic in preferring pattern but preferred best solid on the whole. Demand performance of men's suit appeared by five main causes of design, practicality, comfort, appearance appropriateness, another person awareness and functional materials. And most main causes showed difference according to demographic characteristic.

The purpose of this study is to provide the demand information about services (S/W) and infrastructure (H/W) for rural welfare and culture. The survey was conducted on the overall satisfaction level, the condition change, the importance-satisfaction level of each field and the top priority items for administrative agencies and rural residents. In the overall satisfaction level, administrative agencies responded more than 'normal' to all fields, but the overall satisfaction level was lower than 'normal' in the fields excluding the healthcare field in the case of rural residents. In terms of condition changes compared to the past five years, both administrative institutions and local residents evaluated the improvement. IPA analysis was conducted to identify the priority ranking of each field and it was found that emergency medical facilities in the healthcare field, infant day care facilities in the social welfare field, movie theaters in the culture field, lifelong education institutions and academy facilities in the education field and private sports facilities in the leisure and sports field were most needed, respectively. The results of this study are expected to be helpful in increasing the efficiency and presenting the improvement direction about the development policy of the rural culture and welfare.
