교통정책에 대한 평가는 평가자의 관점에 따라서 차이가 있기 때문에, 단순한 빈도분석보다는 평가대상에 대해서 정확한 인지 서열화를 통한 분석이 필요하다. 본 연구는 대도시의 교통정책에 대한 평가를 위하여, 도로소통, 대중교통, 주차, 보행환경, 광역교통, 교통정보, 교통전체 7개 분야에 대해서 다차원척도법인 ALSCAL법과 MDPREF법을 시용하여 분석을 하였다. 포지셔닝한 결과, 각각 4개 집단으로 분류되었으며, 전체적으로는 비슷한 경향을 나타내었으나, 아이디얼 포인트 모형인 ALSCAL법은 지능형 교통체계의 도입 유무에 따른 교통정책별 개선정도, 벡터 모형인 MDPREF법의 경우는 특정 기능의 확충 내지 구축에 따른 교통정책별 개선정도에 대한 인지경향이 있는 것으로 대별되어 나타났다. 따라서 향후 교통정책을 수립할 경우에는 아이디얼 포인트 모형인 ALSCAL법과 벡터 모형인 MDPREF법을 우선적으로 수행하여 평가자의 정확한 인지 서열화를 기한 후, 이를 함께 고려한 교통정책을 수립, 제시하는 것이 바람직한 것으로 나타났다.

According to the activation of the fashion electronic commerce, this research investigated the merits and demerits and improvement plan of the 3D virtual try-on technology using the qualitative research method. This research was performed by interview with 70 evaluation group. The evaluation group of 3D virtual try-on was organized and the fit evaluation process by 3D human body scan and the 3D virtual try-on of the i-Fashion technology center were experienced. This study was performed by interview after the actual and virtual try-on about the casual shirt. The convenience and accuracy of measurement, usability in online shopping, body evaluation, complement of sizing system, and body shape management were discovered as merits. The requirement of high accuracy in sizing and avatar, limits of fabric expression, practical limitation by cost, vexatious of measurement garment, differences between real and virtual fittings, personal information leakage risk, and etc were pointed out as demerits. The mass customization, customized garment connected with medical service, humanized avatar, improved fitting report, entertainment, coordination, wardrobe manager were proposed as improvement plan.

Objectives : The aim of this research was to develop evaluation indicators that ensure safe services and enhance the quality of small-sized dental hospitals within local communities to prepare for the dental hospital accreditation system. Methods : Materials and data from a total of 460 respondents were analyzed after quality improvement indicators were formed by surveying experts and studying documents in Korea and abroad, and by conducting a survey from August 21, 2013 to September 30, 2013 for validation purposes. Results : Based on the results of factor analysis. all measured items appeared to be statistically significant with a factor loading score of at least 0.5, and the correlation between the factors all appeared to be high as well. The goodness-of-fit for the model also appeared to be within the recommended acceptance level. Thus, the proposed evaluation indicators for dental hospital accreditation developed in this study consisted of a total of seven major category factors and a total of 91 detailed items. Conclusions : Furthermore, the results suggest that the evaluation indicators can be used to improve the quality and to ensure the safe services of dental hospitals in local communities.

Development of social overhead capital (SOC) requires huge national finance, and performance issues such as cost-efficiency, safety, and environment have been constantly raised. However, currently each construction client has limited access to its own projects' performance without analytic methodology for industry-level comparisons and benchmarking for improvement. To overcome this problem, this study proposes a comprehensive performance analysis framework for post-evaluation of large-scale construction projects. To this end, this study performed a case study of advanced countries (the U.S., the U.K. and Japan) and consultation with related experts to develop a tailored performance analysis framework for the Post- Construction Evaluation and Management system in Korea. The developed framework covers three categories (project performance, project efficiency, and ripple effect), nine areas (cost, schedule, change, safety, quality, demand, benefit-cost ratio, civil complaint, and defect), and 31 detailed metrics. Using industry-level project performance database and statistical techniques, the proposed framework can be used not only to diagnose excellent and unsatisfactory performance areas for completed construction projects, but also to provide reference data for future similar projects. This study can contribute to the improvement of clients' performance management practices and effectiveness of construction projects.

국가 R&D사업은 적절한 예산 규모 산정이 어렵기 때문에 참고 가능한 해당 사업의 성과 및 평가정보가 적시에 지원될 경우 판단의 오류를 최소화 할 수 있을 것으로 기대할 수 있다. 그러나 현실적으로는 국가 R&D사업에 대한 성과평가 결과가 의도한 대로 충분히 활용되지 못하고 있는 실정인데, 그 이유로는 크게 두 가지 문제점을 들 수 있다. 첫째, 국가 R&D사업의 성과 및 평가 정보와 관련 예산정보가 적시에 연계 활용되지 못하고 있다. 둘째, 이를 지원하는 시스템간의 연계가 구현되어 있지 않다. 따라서 본 연구에서는 국가 R&D사업의 현황 분석을 신정부 출범 이전과 이후의 제도적, 시스템적 관점에서 고찰하였고 이를 통하여 국가 R&D성과평가와 예산 정보가 연계 가능하도록 개선 프로세스를 제안하고자 하였다.

When a ship is course-keeping in the open seas, autopilot system is adapted. The design of autopilot system is very important for improvement of ship′s element research. Automatic steering system consists of autopilot device, power unit, steering gear, magnetic or gyro compass and ship dynamics. In order to evaluate automatic steering system of ships in open seas. we need to know the characteristics of each component of the system, and also to know the characteristics of disturbance to ship dynamics. In this paper, I provide evaluation method of autopilot navigation system of the fishing ship. Prediction method based on the principle of linear superposition is introduced for irregular disturbance. For the evaluation of automatic steering system of a ship, "performance index" is introduced from the viewpoint of energy saving and calculation method is frequency response analysis. Finally, I carried out calculation of sensitivity of control constants of autopilot with various conditions of ocean environments.

Computer system performance has always had the possibility of affecting business profitability, but with the advent of the World Wide Web where customers interact directly with Web servers, response time can have a direct and dramatic impact on business revenue. This paper is written in the operation environment and system analysis of HTS(Home Trading System) running K Securities. This paper also shows the method for performance improvement through investigation and analysis for the overall systems resources whether HTS has an appropriate performance or not. Performance analysis includes specially CPU analysis, Memory analysis, Disk Input/Output analysis and application analysis. Besides providing more detailed server specification for expansion from now on, system performance can be maintained with effect in the future. Through this study it is possible to manage the performance of HTS more easily and to solve problems such as a bottleneck more quickly.

In traditional programing education, computers were used as the main tool. Consequently, it was problematic to provide education in an environment without computers or for learners without computer skills. To address this problem, this study developed and validated an unplugged robot education system capable of computerless programming education. The key feature of the proposed system is that programing can be done only by connecting programming blocks in symbols of a flow chart with built-in commands. Validation of the system was performed by a specialist group. Validity was very high with values of content validity ratio (CVR) over 0.7 in all evaluation criteria except "Ease of error debugging" and "Linkages to educational curriculum," whose CVR values were each 0.6. Future directions include improvement in the two areas that scored lower than the others did by, respectively, system improvement to support debugging in error conditions that may occur during the programming process, and development of user guide to support linkages to educational curriculum.
