콘크리트 구조물의 골조공사에서의 주요 공정 중 하나인 거푸집 공사는 전체 건축공사의 공사기간 및 공사비 측면에서 상당 부분을 차지하고 있다. 하지만 공사현장의 조건을 고려한 거푸집의 적정시스템 선정은 현재까지 현장실무자의 경험에만 의존하고 있는 실정이다. 본 논문에서는 거푸집 공법 선정 요인에 대한 정량화된 분석을 바탕으로 슬래브 거푸집 중 신공법과 기존 공법을 선정하여 각 공법의 성능을 정량화된 분석데이터를 바탕으로 평가했다. 이를 통하여 각 공법들의 정성적 항목에 대한 정량화된 평가점수를 산출하여 슬래브 거푸집의 현장 적용성에 대한 평가 방안을 제시하였다. 따라서 본 논문에서 사용된 델파이 기법의 방법론은 다른 공법들의 선정, 평가에도 사용될 것이라 사료된다.

Purpose: The purpose of this study was to analyze reports of qualitative research published in Journal of Korean Academy of Fundamentals of Nursing (JKAFN). Methods: Twenty four qualitative research studies using in-depth interviews and focus group interviews published in JKAFN from 1994 to 2014 were selected for analysis. Chosen reports were analyzed by consolidated criteria for reporting qualitative research (COREQ), which is a reporting guideline for qualitative research. COREQ consists of 32 items and 3 domains. Results: In the 1st domain, the relationship of researchers and research participants, bias and understanding of the researchers on the study phenomenon were analyzed less than other items. In the 2nd domain, methodological research was carried out across various qualitative studies, but the description of the research environment and research questions for the interview guidelines was insufficient. In the 3rd domain, research results and data were consistent, but data showing opposing content and explanations of negative practices were not done at all. Conclusion: These results indicate a need for the development of evaluation tools for qualitative research and items should be added to improve the reliability and validity, research should be related to the ethics in the framework of the COREQ.

In this study, the purpose is to present the foot inclination angle for realizing an image similar to that of the existing examination method and to present the clinical usefulness of the new examination method through comparison between the existing examination method and the newly designed standing foot oblique projection. A foot phantom was used, and the magnification of the image according to the angle was quantitatively evaluated by attaching a nut to the position of the cuboid of the phantom. The internal oblique image acquired using a 30° wedge was set as the standard image. And that image was compared with the images acquired by changing the angle of the foot from 20° to 65° at intervals of 5°. Image evaluation was performed by 3 radiological technologists, and qualitative evaluation using a Likert 5-point scale for evaluation items of true oblique view and quantitative evaluation of the value obtained by measuring the diameter of a nut in each image were performed as image evaluation. For data analysis, reliability analysis between the measure and comparative analysis of the average value for each angle were performed. The qualitative evaluation score for each image was 4.5 to 5 points for most questions in the case of the standard image. And 4 points or less for most questions in the images with a foot angle of 45° or less, and an evaluation score close to the standard image was obtained in the image of 50° or more. And in the quantitative evaluation, the diameter of the nut was measured to be 9.28~9.56 mm. The qualitative evaluation showed a reliability of 0.95~1.0 and the quantitative evaluation was 0.62. As a result of comparing and analyzing the average of the quantitative and qualitative average values for each angle image, the group with the average value most similar to the standard image was images obtained at 55° and 60°, and in the post-analysis, the images of both groups were the same group as the standard image(p<0.01). As a result of this study, it was found that the angle of inclination of the foot for realizing the image most similar to the existing image in the standing foot oblique projection is 55°~60°. In addition, if this test method is applied to the clinic, it is believed that it will help prevent safety accidents such as falls during the test and improve test efficiency by minimizing the movement of patients for the test.

The purpose of this study is to derive implications for improving related policies and evaluation criteria in the future by analyzing trends of evaluation criteria for industry-university cooperation in Korea. For this purpose, five surveys on industry-university cooperation by government departments, major general university evaluations, and evaluation indicators of specialized industry-university evaluations by the Ministry of Education were analyzed. As a result, most of the evaluation criteria for domestic industry-university cooperation have been composed of quantitative indicators and have a limited character as quantitative performance management for government projects. Although the Ministry of Education's evaluation criteria for industry-university cooperation projects has gradually changed to a segmented index considering universities, industries, and regions, it needs to be supplemented for sustainability of industry-university cooperation. In order to promote sustainable industry-university cooperation in the future, it was suggested that first, it is necessary to supplementation of qualitative Indicators considering each university's characteristics, second, the composition of indicators related to reflect on demand in the process of the cooperation, and third, to build a virtuous cycle system for future operation of evaluation criteria.

Evaluation is to be seen a~ a central component of design activity. It is an attempt to ensure that the proposal which arises is accepted and that the resulting artefact itself suited to its purposes in practice. Recent surveys of Evaluation show that most methods require quantitative and explicit attributes. Always a significant part of the attributes of design proposals is qualitative. Therefore we need some study that convert qualitative attributes into quantitative scale values, because in many cases con\ulcornerclusions can be drawn about the order of the overall value of the design proposals. Following to Thurstone's psychological scaling methods, attributive values are assigned by ruting scale methods, met, hod of rank-order and method of paired comparisons. The problem of psycho\ulcornerlogical scaling is then to determine whether the stimuli can be ordered on a psychological continuum with respect to the degree of the attributes each possesses. The law of comparative judgement assumes that for a given stimulus there is associated a most frequently aroused or modal discriminal process on a psychological continuum. This paper is based upon the premise that the modal discriminul process will also be the same as the mean or median of the distribution.The objective of this paper is to argue for an acceptance of qualitative approaches to the evalua\ulcornertion of Design as a complement to the existing quantitative techniques. The scale values of 10 attri\ulcornerbutes \ulcorner(1) originality, (2) aesthetics, (3) satisfaction, (4) effeciency, (5) function, (6) size, (7) texture, (8) simplicity, (9) symbol, and (10) facility) in case of TV sets are obtained and their interactions are examined.

Most design practices have not taken advantage of the advanced theories in the modern fracture mechanics and finite element analysis due to complexity of analysis as well as the large quantity of vaguely defined parameters in actual designs. This paper considers fatigue problems in bridge structures using effective analytical and design tools from the field of qualitative constraint reasoning. A set of software modules was developed for fatigue analysis ,and evaluation, which is easily applicable in engineering practices of bridge designers. The software modules integrate techniques in the field of knowledge representation and qualitative reasoning, into the conventional fatigue analysis. The techniques enable the use complex analysis formulations to tackle practical problems with uncertainties, and present the design outcome in two-dimensional design space. Appropriate engineering assumptions and judgments in carrying out these procedures, often the most difficult part for practicing engineers, can be partially produced by using qualitative reasoning to define the trends and ranges, interval constraint analysis to derive the controlling parameters, as well as design space to account for practical experience. This paper depicts a way of complex analysis to practical engineering designs with qualitative reasoning.

The objective of public works planning is being converted from economic growth to sustainable development. So, the demand for considering social & ecological influences as well as economic components had been increased in evaluation of public works planning. In evaluation of public works, its components related with benefit and cost in feasibility analysis can be classified to qualitative and qualitative elements. Qualitative elements are evaluated by qualitative methods which can manage various items, be commonly applied nationwide, and consider elements that can be calculated numerically such as environments, willingness, etc. In this study, using the concept of 'Information measure', a method to design planning of rural works is proposed. 'Information benefit model' for rural works can evaluate present plan in the side of provider's and demander's 'benefit'. And, optimizing method of rural works by 'Information benefit' can simulate present state and optimize the site and route of rural works.

Background: To compare the value of contrast-enhanced ultrasound (CEUS) qualitative and quantitative analysis in the identification of breast tumor lumps. Materials and Methods: Qualitative and quantitative indicators of CEUS for 73 cases of breast tumor lumps were retrospectively analyzed by univariate and multivariate approaches. Logistic regression was applied and ROC curves were drawn for evaluation and comparison. Results: The CEUS qualitative indicator-generated regression equation contained three indicators, namely enhanced homogeneity, diameter line expansion and peak intensity grading, which demonstrated prediction accuracy for benign and malignant breast tumor lumps of 91.8%; the quantitative indicator-generated regression equation only contained one indicator, namely the relative peak intensity, and its prediction accuracy was 61.5%. The corresponding areas under the ROC curve for qualitative and quantitative analyses were 91.3% and 75.7%, respectively, which exhibited a statistically significant difference by the Z test (P<0.05). Conclusions: The ability of CEUS qualitative analysis to identify breast tumor lumps is better than with quantitative analysis.

본 연구에서는 정성분석기법과 현장측정을 통한 분기기 고정 망간크로싱의 피로수명평가 기법에 대한 분석을 다루었다. 공용중인 분기기 망간크로싱에서의 현장측정 결과를 바탕으로한 피로수명평가와 마찰에 의한 단면강성의 변화를 고려한 정성분석기법을 이용하여 망간크로싱의 피로수명을 분석하였다. 대부분의 강재 피로설계에서는 해석 자체의 복잡성 이외에 요구되는 많은 입력 변수들로 인해 설계 단계에서의 불확실성이 발생하며 이에 따라 파괴역학 및 유한요소법에 관한 진보된 이론을 적용하기에 어려움이 있다. 그러나 본 논문에서 제시한 정성분석기법을 이용하면 복잡한 피로해석 및 평가를 설계자들로 하여금 실무에 쉽게 적용할 수 있게 한다. 또한 복잡한 해석변수에 따른 해석결과를 2차원 공간해로 표현함으로써 해석 단계에서의 불확실성을 보완하여 검토자들로 하여금 해석결과의 경향과 범위를 정의할 수 있게 하여 복잡한 해석 공식을 사용하는 노력을 저감시킬 수 있다. 본 논문에서는 이러한 설계에서의 불확실성과 복잡성을 줄일 수 있는 설계 도구를 발전시키려 노력했으며 그것으로 하나의 해법 자체가 단일 치수로 나타나는 것이 아니라 어떤 영역으로 표시되어 선택의 폭을 제시함으로서 판단할 수 있게 되었다.
