Purpose: In Korea, buildings make up 20.5% (2012) of the gross national energy consumption, so they are a major target for greenhouse gas reduction. In particular, energy consumption in multihousing represents approximately 32.6% of the entire building sector. With improving energy performance being the focus, efforts are continuously being made to reinforce standards and systems in greenhouse gas reduction. This study investigated the current status of multihousing in Korea in terms of energy performance as described in the performance evaluation reports submitted (to an institution that specializes in reviewing the performance evaluation of green homes) based on the construction criteria and performance codes for green homes and examined if the evaluation criteria using related methodologies were appropriate. The results will provide helpful information for reviewing the future directions of operations and amendments to the systems. Method: The overall characteristics of the system were examined using the evaluation methodologies (and current state of revisions) of the performance codes for green homes and comparing them with similar systems. Also, the current state of application and energy performance (conducted according to the evaluation methodologies) were compared by the evaluation institution for multihousing neighborhoods that were assessed for five years from 2010 to 2014. Result: It has been confirmed that the performance codes for green homes are different from other similar systems in evaluating performances of multihousing in that they allow both quantitative and qualitative methods of evaluation, and they consider both energy and sustainability simultaneously in the evaluation. Furthermore, regarding the adoption rate of the forms for the two evaluation methods (Form 1 - quantitative and Form 2 - qualitative), the rate preferring Form 2 increased gradually in time to reach 55.3% in 2014. In analyzing the rate of overall energy reduction (submitted in Form 1) and the coefficient of thermal transmission for each part (submitted in Form 2), it was observed that the deviation between the performance submitted and the criteria decreased in line with the level of reinforcement.

기존의 OSS의 활용은 운영체제나 DBMS와 같은 시스템 애플리케이션의 사용이 주를 이루었다. 그러나 현재 많은 기업에서 시스템 소프트웨어가 아닌 응용 애플리케이션 중심으로 OSS를 활용하려고 한다. 그러나 OSS를 활용한 응용 애플리케이션 개발을 위해서는 기반이 되는 OSS의 선정이 무엇보다 중요하다. 기존의 OSS 평가 연구의 범위는 전체 OSS 품질을 포함하고 있다. 그러므로 OSS 선정에 대한 평가 연구는 미흡하다. 또한 평가의 결과는 정량적인 측정보다 정성적인 측정에 기반하고 있다. 본 연구에서는 기존의 OSS 평가지표들 중 선정을 위한 지표들만을 도출하고 이를 기반으로 프로젝트 특징에 따라 정량적인 평가가 가능한 평가지표를 제안한다. 제안하는 평가지표는 OSS 커뮤니티 내의 정보만을 가지고 평가할 수 있는 초기평가지표와 정량적인 측정이 가능한 상세평가지표로 구분하여 제안한다. 이를 통해 OSS 선정 시 정량적인 점수와 지표를 통해 객관적인 근거를 제공한다.

This study explored medical students' major research topics and research methods by analyzing 184 academic articles pertaining to the characteristics of medical students from 2007 to 2017. Results showed many papers dealing with medical students' emotional and cognitive aspects, student counseling, clinical practice education, and curriculum management. According to the medical education accreditation board, research trends were found mostly in the student and curriculum areas of learner characteristics, medical humanities, student counseling, clinical practice education, and curriculum management. Common research topics have been steadily increasing since the introduction of the evaluation accreditation standard in 2012. Medical students predominantly used quantitative research methods for the studies. In the future, it is necessary to ensure that research topics such as CQI, digital- and performance-based clinical practice, and convergent curriculum within the Fourth Industrial Revolution are being studied. In addition, it is crucial to investigate learners' unique, dynamic, and qualitative characteristics through qualitative and mixed methods.

전 세계적으로 융복합 지향적 연구활동이 강화됨에 띠라 연구분야의 다양성과 새로운 연구분야의 개척은 물론 국가간 협력을 통한 연구가 활발히 진행되고 있다. 이러한 새로운 형태의 연구가 계속 발굴되고 있는데 반해 그 연구를 정확히 평가하고 객관적으로 검증하는 방법에는 한계가 있는 현실이다. 동료평가(peer Review)만으로는 정확한 연구과제 평가가 제한적이라는 인식이 확대되고 있으나 이를 보완할 객관적인 평가방법의 제사는 아직 실증적으로 검증되지 못하고 있다. 따라서 본 논문에서는 최근 새롭게 추진된 국가연구개발사업에 동료평가와 신규 계량지표에 의한 평가를 적용하여 그 결과의 반영비율 및 상관도를 측정하였다. 그 결과 계량지표의 적용이 실증적으로 유의미한 결과를 갖는 것으로 분석되었다.

Purpose : The purpose of this study was to analyze Korean qualitative research studies on cerebral palsy and provide a basis for future direction of research. Methods : Twenty-six articles were selected by searching 4 Korean databases (NDSL, DBpia, KISS, and RISS) and reviewing the list of additional references. All the articles were analyzed and assessed using the Consolidated criteria for Reporting Qualitative research (COREQ). Results : Seventeen qualitative studies and 9 mixed quantitative and qualitative studies were selected, and methodologies such as case study (42.3 %), constant comparative method (23.1 %) and phenomenology (23.1 %) were used. The studies investigated the effects of interventions (38.5 %), support programs (30.8 %), and life experiences (26.9 %). Among the participants, 50.0 % were persons with disabilities only, 19.2 % were parents only, and 30.8 % were combination of persons with disabilities, parents, teachers, and therapists. The number of participants in most studies was 2-9 (57.7 %). The COREQ evaluation of the selected articles revealed many shortcomings in the studies. Interview guidelines were used only in 26.9 % of the studies. In particular, many articles did not describe in detail the characteristics of researchers and the relationship between researchers and the participants. Conclusion : In future, various research methodologies and research checklists must be used to stimulate high-quality qualitative research with on cerebral palsy.

When investigating the droplet, spray, and impact of liquid on a solid plate, backlight imaging has been widely used to understand these phenomena. However, some previous studies have suffered from poor image quality. In this study, various combinations of image processing algorithms, such as white image correction, histogram equalization, CLAHE, Otsu's binarization, and multi-Otsu's binarization, have been applied to flash boiling spray images to enhance image quality for qualitative observation and semi-quantitative spray angle evaluation. To acquire images with high contrast for qualitative observation, applying CLAHE was effective, making small droplets and detailed shapes of the jet noticeable. However, when images were averaged to determine spray angle or penetration length based on intensity, this method induced artifact unphysical patterns, thus requiring careful consideration. Based on the algorithm proposed in this study, the spray angle variation according to injection pressure and temperature has been calculated, showing a reasonable trend.

The proposed system measures business performance by considering both VA(Value-Added), which represents stakeholder's point of view and EVA(Economic Value-Added), which represents shareholder's point of view. To do so, we suggest a business performance scheme which utilizes VA per Capita (Value- Added/Workers) and EVA to Invested Capital(Economic Value-Added /Invested Capital). For effective measurement of business performance, we consider simultaneously not only quantitative financial factors such as VA, EVA and cash flow but also qualitative value drivers such as defect ratio, inventory level, customer satisfaction, enterprise culture and so on. However, we don't consider the qualitative factors due to the limited data. To demonstrate the performance of the system, we conducted a case study using financial data of Korean automobile industry over 16 years from 1981 to 1996, which is taken from database of KISFAS (Korea Investors Services Financial Analysis System).

3차원 영상 해석 기법에 의해 구해진 DEM(Digital Elevation Map)을 정량적으로 평가하는 것은 영상 해석 기법의 유효성을 검증하기 위해 매우 중요하다. 본 논문에서는 모의 영상 제작에 의한 3차원 재구성 과정의 새로운 정량적 평가 방법을 제안하였다. 제안된 방법은 미리 확보된 DEM과 정사영상(ortho-image)을 가상의 실제 값(pseudo ground truth)으로 가정한 것에 의한 것이다. 제안된 방법의 과정은 그래픽스에서 사용되는 ray tracing 알고리즘을 구성하여 가상의 실제 값에 적용함으로서 원하는 시점으로부터의 한 쌍의 모의 영상을 제작하는 것으로부터 시작된다. 제작된 모의 영상 쌍으로부터 구해진 DEM을 가상의 실제 값과 비교하면 구해진 DEM의 정량적인 오차 분석이 가능하여, 적용된 3차원 영상 해석 기법의 유효성이 평가될 수 있다. 제안된 평가 방법의 타당성을 검증하기 위해, 정량적 및 정성적인 실험이 수행되었다. 이를 위해 발생되는 모의 영상이 실제 형상을 재현하는 정도를 정량적인 수치로서 구하여 제안된 방법을 타당성을 입증하였다. 또한 정합창의 크기 변화에 따른 DEM의 정확도를 제안된 평가 방법에 의해 실험하였다. 이러한 실험 결과가 예견된 결과와 일치함에 의해 제안된 평가 방법의 타당성을 정성적으로도 명백히 증명하였다.
