본 연구에서는 홍천강, 미호천, 내성천을 평가 대상하천으로 선정하여, '하천의 생물서식처 복원을 위한 하천 자연도평가 : I. 평가방법의 제안'에 따라 하천자연도평가를 시행하였다. 하천자연도의 종합평가결과 홍천강은 2등급(평균 1.92), 미호천은 2등급(평균 1.43), 내성천은 2등급(평균 2.31)으로 평가되었다. 수질과 하천자연도평가의 상관관계를 비교ㆍ분석한 결과, 수질과 하천자연도 종합평가결과의 상관계수가 0.575로 상관성이 매우 작게 분석되어, 하천자연도평가가 수질평가와 다른 관점에서 하천의 생태계를 평가하는 지표로 활용이 가능한 것으로 분석되었다.는 지표로 활용이 가능한 것으로 분석되었다.

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.

음성인식은 최근 인공지능 기술과 접목되면서 오인식률이 크게 개선되었고 사용자 관점에서 효과적이고 효율적인 HMI(Human Machine Interface)를 제공하고 있다. 이러한 추세는 방위산업 분야에서도 반영되고 있고 특히 항공분야에서 F-35에 적용이 되었다. 하지만 이러한 기술에 대해서 품질평가를 위해 방위산업 특히 항공분야에는 객관적이고 평가 가능한 정량적인 모델이 필요하다. 본 연구에서는 이러한 음성인식의 소프트웨어 측면에서 항공기에 적용하기 위한 정량적인 평가 모델을 제시한다. 평가 모델 제시를 위해 음성인식 적용 기술과 ISO/IEC 25000(SQuaRE) 제품 품질 속성을 이용해 평가 항목을 추출한다. 이러한 두 가지 항목의 연계를 통해 정량적인 평가 모델을 제시하고 사례 연구를 활용해 평가 결과를 확인한다.

Through text mining, sentiment analysis, and semiotics analysis, this study aims to reinterpret the meaning of user emotional words and related words to derive strategic elements of brand and design. After selecting a local car manufacturer whose user opinion on the brand is a clear topic, web-crawl the car comments of the manufacturer directly created by the users online. Then, analyze the extracted morphology and its associated words and convert them to fit the marketing mix theory. Through this process, propose a methodology that allows consumers to supplement and improve brand elements with negative sensibilities, and to inherit elements with positive sensibilities and manage brands reasonably. In particular, the Map presented in this study are considered to be fully utilized as information for overall brand management.

현장조사를 통해 암반사면의 안정성을 평가하기 위해서 여러 연구자들에 의해 평가법이 제안되었다. 그러나 기존의 평가법들은 제안자의 주관적 판단에 의해 평가항목의 선정과 가중치가 달리 적용되고 있어 평가법에 따라 안정성 평가결과도 서로 상이하게 나타나고 있다. 따라서 각 평가항목에 대한 가중치의 객관성을 확보하기 위해 로지스틱 회귀분석을 실시하여 안정성 평가법을 제안하였다.

This paper presents the concepts developed to propose Distributed Control System(DCS). To achieve adequate satisfaction under various conditions, the DCS should be designed from two points of view of functions distributions and performance planning. Performance evaluation criteria can be specified by the response time between units and the utilization of each unit. One has to also consider the ease and the cost of installation, maintenance, repair. Based on these characteristics, different system configuration can be evaluated and compared through results about evaluation criteria in order lo select the best DCS for particular process. The results, in abbreviated form, of the simulation DCS controlling a CAL(Continuos Annealing Line) plant of iron process ate presented.

A modified equation for the evaluation of discomfort of a seated human body exposed to differential vibration at the seat and the floor was proposed in this paper. Through the review and analysis of the preceding studies, effect of phase difference between the seat and the floor vibration on discomfort were quantitatively identified. The phase effect was shown to be governed by not only phase difference between the two vibrations but both their frequency and the magnitude, which means the present equation for the evaluation of perceptual amount of vibration provided by ISO 2631-1 should be modified. The proposed equation was developed such that the correction function was multiplied to the present equation. The correction function consisted of three parts, each of them represented the effect by phase difference, frequency and vibration magnitude on discomfort respectively.

Most real world design evaluation and risk-based decision support combine quantitative and qualitative (linguistic) variables. Decision making based on conventional mathematics that combines qualitative and quantitative concepts always exhibit difficulty in modelling actual problems. The successful selection process for choosing a design/procurement proposal is based on a high degree of technical integrity, safety levels and low costs in construction, corrective measures, maintenance, operation, inspection and preventive measures. In this paper, a design decision support framework using a composite structure methodology grounded in approximate reasoning approach and evidential reasoning method is suggested for design evaluation of machinery space of a ship engine room at the initial stages. An illustrative example is used to demonstrate the application of the proposed framework.

현재의 안전설비기준은 정량적 관점에서 정의되었고, 선박 재난 시나리오에 관한 대응수준을 평가할 방법이 없다. 선박, 특히 여객선 승객의 안전성을 향상시키기 위해서는 설계단계 혹은 증개축단계에서 성능기반의 피난안전설계에 의한 평가를 통해 문제점을 파악하고 개선안을 제실할 필요가 있다.
