  • Regulation for the testing and operation of autonomous vehicles on public roadways has been recently developed all over the world. For example, the licensing standards and the evaluation technology for autonomous vehicles have been proposed in California, Nevada and EU. But specific safety evaluation scenarios for autonomous vehicles have not been proposed yet. This paper presents safety evaluation scenarios for extraordinary service permission of autonomous vehicles on highways. A total of five scenarios are selected in consideration of safety priority and real traffic situation. These scenarios are developed based on existing ADAS evaluation and simulation of autonomous vehicle algorithm. Also, Safety evaluation factors are developed based on ISO requirements, other papers and the current traffic regulations. These scenarios are investigated via computer simulation.

  • 장애인의 운전 교육 이수 과정은 어려움과 불편한 부분들이 많다. 운전 교육 내용 부분에서도 실제 운전 주행 중 예측할 수 없는 다양한 돌발상황들이 발생한다. 현재 시행하고 있는 운전 교육 과정에서도 돌발상황에 대한 교육들이 이루어지고 있으나, 다양한 돌발상황에 대처하는 교육은 미비하다. 이에 본 논문에서는 유니티 기반의 장애인 운전 교육 시뮬레이터를 제안한다. 유니티를 이용하여 다양한 돌발상황에 대한 시나리오를 구성하여 시뮬레이터를 제작한다. 피실험자들을 통하여 모의주행을 실시하여, 평가항목에 따른 기존의 돌발상황에 대한 대처 점수를 평가한다. 기존의 운전 교육 시뮬레이터에 비해 제안 시스템의 돌발상황에 대한 대처 능력의 평가점수가 높게 나온 것으로 확인되었다. 제안 시스템을 활용하면 돌발상황에 대한 대처 능력 향상과 실제감 높은 운전 체험을 통하여 삶의 질을 높이는 것을 기대할 수 있다.

  • Legislation on pharmaceutical reimbursement decision using economic evaluation results was made in Korea in fm, but has yet to be fully implemented. We evaluated the quality of Korean economic evaluation studies of pharmaceuticals to understand gaps between legislation and implementation. From this evaluation, we propose policy options that might strengthen the research Infrastructure In order to support such studies. We reviewed 23 published studies for drugs conducted between 1996 and 2004. Evaluation criteria included methodological characteristics, healthcare system characteristics, population characteristics, and applicability of results. Large variation in study quality was observed, particularly with study design, outcome data, treatment patterns and interpretation. Korean clinical data used was mostly from observational studies of 1-2 hospitals. Foreign data was extracted from clinical trials that did not Include Asian population and their selection criterion was not clarified. With respect to treatment patterns, medical records and hospital bills were used without adjustment regarding area, hospital type, and others. And next frequent situation relied on expert opinion from academic physicians in specialty practice. preference measures, when used, were not elicited from the Korean population. $78.3\%$ of studies did not clarify the funding source. If the Korean economic evaluation policy is to provide meaningful data for decision makers, the quality of cost-effectiveness studies will need to improve dramatically. This may involve access to or creation of better data, more diverse funding, unproved training of researchers and evaluators, and partnerships with technology manufacturers.

  • Autonomous vehicle is a car which drives itself without any human interaction. SAE provides technical definitions for autonomous and international standards for test evaluation. Accordingly, automobile industry is actively researching development and evaluation of various ADAS (Advanced Driver Assistance Systems), : representative technology of autonomous technology. Recently, ADAS is in the commercialization level such as ACC, LKAS, AEB, and HDA etc. And it also has issues about safety evaluation. The purpose of HDA in ADAS is reduced the driving load on highway. It has a function which can maintain lane keeping and control distance from forward vehicle. This function is evaluated to be useful for accident prevention. Therefore, this paper proposes the safety evaluation scenario of HDA, considering the domestic highway design criteria and the situation that may arise on the actual highway. We compared and analyzed the data acquired through simulation and actual vehicle test. And verified the reliability of the proposed safety evaluation scenario. The verified result is expected safety evaluation of HDA is possible even under the bad condition, which cannot be tested.

  • Graduates from engineering colleges are demanded to have been acquired some abilities and qualities during their undergraduate years through the standard of the so-called "programmed learning results and evaluation" This paper aims at analyzing the learning results evaluation tool for graduates from the architectural engineering department through the examples of the colleges with engineering accreditation in Korea, and suggesting a more appropriate programmed learning result evaluation tool. The basic theories on programmed learning results were studied, and then the previous study examples were researched. The study objects were limited to the fourteen colleges which offered the examples of the learning results evaluation tools of the colleges with engineering accreditation in Korea. Types and the present situation of those evaluation tools were analyzed. In addition, the proposals for the evaluation tool of programmed learning results and the performance standard were suggested for those with an engineering accreditation, based on the case study of the performance standards of each college with an engineering accreditation. The study results showed that much more national research needs to be conducted to clarify the standards of selecting an evaluation tool and a performance standard appropriate for the level of each college so that it can make a proper proposal.

  • The modern market is highly competitive. It has progressed from traditional competition between enterprises to competition between supply chains. To ensure that enterprise can form the best strategy consistently, it is necessary to evaluate the trust of other enterprises in the supply chain. First, this paper analyzes the background and significance of supply chain trust research, analyzes and expounds on the qualitative and quantitative methods of supply chain trust evaluation, and summarizes the research in this field. Analytic hierarchy process (AHP) is the most frequently used method in the literature to evaluate and rank criteria through data analysis. However, the input data for AHP analysis is based on human judgment, and hence there is every possibility that the data may be vague to some extent. Therefore, in view of the above problems, this study improves the global trust method based on chain iteration. The improved global trust evaluation method based on chain iteration is more flexible and practical, hence, it can more accurately evaluate supply chain trust. Finally, combined with an actual case of Zhaoxian Chengji Food Co. Ltd., the paper qualitatively analyzes the current situation of supply chain trust management and effectively strengthens the supervision of enterprises to cooperative enterprises. Thus, the company can identify problems on time and strategic adjustments can be implemented accordingly. The effectiveness of the evaluation method proposed in this paper is demonstrated through a quantitative evaluation of its trust in downstream enterprise A. Results suggest that the subjective preferences of and historical transactions together affect the final evaluation of trust.

  • 유아시기 정서발달은 전반의 발달에 중요한 의미를 갖는다. 지속적인 마음 상태인 정서는 일시적인 마음상태인 감정의 인식과 처리가 핵심 자원이 되어 발달한다. 본 연구의 목적은 정서발달에 중요한 유아시기 감성인식 기술을 이용한 교사의 효율적인 감정코칭을 제안하며, 그 효과의 유의성을 정량적으로 검증하고자 한다. 교사2명, 유아 42명 피험자를 대상으로 기준 무자극, 행동코칭, 감정코칭, 감성인식 시스템 피드백 감정코칭 자극을 제시하였고 영상기반 집단의 행동 양과 유아 개별의 주관평가 그리고 Heart Math Tools을 이용하여 HRC (Heart Rhythm Coherence)을 측정하여 분석하였다. 결론적으로 유아의 주관평가, 영상의 움직임 양, HRC (Heart Rhythm Coherence)수치는 감성인식시스템 피드백 수업 시 긍정적인 유의한 차이를 보였다. 단 주관평가는 감정코칭과 감성인식 시스템 피드백과는 차이가 나지 않았지만 정량적인 데이터 유아의 행동 양에서는 그 양이 증가하는 결과를 확인하였다. 이는 유아의 주관적 반응에 미흡한 정보를 정량적 데이터로 보완 할 수 있으며, 기관에서 정서교육의 효과적 접근으로 감정코칭 교육 프로세스 시스템을 제안하며 아동 정서발달의 정량적 연구 활용이 가능할 것으로 사료 된다.

  • 항해장비의 성능이 고도화되고 있으나 해기사의 항해기기 운용능력, 즉 해양사고 저감을 위한 항해사의 위험 예견 능력과 회피의무의 중요성은 지속적으로 증대되고 있다. 이 능력과 의무는 항해사의 인지능력으로도 표현할 수 있다. 해기능력이 상이한 각 선교팀이 선박 조종시뮬레이터로 인명구조조선을 실시하여 나타난 선박의 항적을 기반으로 인지상황 발생 초기대응별 사례를 분석하고, 단계별 항적, ROT 값 등 분석 자료를 인지교육모델, 해기사의 상황인식평가 기초자료로 활용하고자 한다.
