터치 인터페이스 입력방식에서 메뉴를 마우스를 이용하여 입력하는 것 보다 터치입력 방식이 의도하지 않는 터치와 입력의 어려움이 증가하고 있다. 본 연구에서는 버튼메뉴의 최소 형상버튼을 기준으로 형태와 크기변화에 따라서 사용성 평가를 분석하고자 한다. 적용방법으로는 터치 입력방식의 인터페이스 디자인에서 활용 할 수 있도록 회귀 모형식과 인터페이스 인간 수행 평가방법의 대표적인 모형인 피츠의 법칙(Fitts' Law)의 비교분석을 통해서 더욱 효과적인 정량적 수행예측 평가 모형식 적용을 통해서 가능성을 확인하고자 했다. 따라서 터치 환경에서 적용할 수 있는 버튼의 형상과 크기변화에 따른 사용자의 사용시간을 고려한 수행예측시간을 디자인에 반영할 수 있다.

The purpose of this study is to analyze the current evaluation methods on faculty performance at Korean engineering colleges and develop teaching evaluation indicators for faculty performance. We investigated the faculty performance cases in engineering colleges inside and outside of the Korea, the engineering faculty's awareness of evaluation factors for their educational performance, and the appropriate ratios by indicating factors. Also we developed evaluation indicators for educational achievements to improve the current faculty performance system. 227 engineering faculty members answered our survey questionnaire. The result in the case study on faculty performance evaluation is as follows. First, most items of faculty performance evaluation are about quantitative indicators that can easily conduct objective evaluation. Second, evaluation items of faculty performance are mostly focused on instruction in a classroom. Third, the evaluation by students and administrative managers is more dominant than that by professors or their colleagues, document evaluation than on site evaluation, general evaluation than formative evaluation, and static evaluation than dynamic evaluation. Lastly, Some universities tend to substitute outstanding articles for underperforming instruction. The evaluation indicators that we have developed can be implemented by four types of subjects, such as students, professors, their colleagues, and deans. Also, based on the evaluation indicators, faculties can freely select their evaluation domains depending on the their tracks, such as a teaching track, a research track, or an industry-university cooperation track. The mandatory evaluation fields include teaching, student counselling, teaching portfolio evaluation by mentors or colleagues, class management evaluation by deans, and self-evaluation. The other areas are optional and professors can choose their evaluation factors.

In the resent years, the early evaluation of concrete quality, construction and maintenance has been considered as all is of major concern due to the increase of loading and the degradation of structures related with time. This paper presents evaluation of structural safety performance using measured data of construction, on the basis of a field measurements for the prevention of unreliable concrete works. Measurements analyzed in this paper are early quality condition and performance assessment, serviceability performance by cracks and deflection, rating performance by loading, durability performance by chloride attack and carbonation. Thus, a quantitative assessment model of resistance capacity was developed here to meet the requirement for deteriorated concrete structures. The model focuses on damage mechanical of concrete structures deteriorated by initial damage factors for concrete quality and environment factors such as chloride and carbonation attacks. These results could provide useful information for concrete structures interested in design, construction and maintenance.

The existing evaluation systems based on financial performance summarize the information about past results and focus on short-term performance, and so they have the limits to explain the future value of firms and to make a long-term strategic performance. By this reason, as a way to increase the future value, the development of the integrated performance evaluation system with which we may manages financial performance and knowledge assets together has been required recently. This study puts together various researches for the evaluation of knowledge assets, and analyzes the existing studies for the domestic medical devices industry and the tendency of introduction for business practice. Under this analysis, this study develops the knowledge asset evaluation indexes for medical devices industry by using the Balanced Score Card (BSC) of Kaplan & Norton(1992), and then presents the evaluation model by applying the Analytic Hierarchy Process (AHP) of Saaty(1980) to get the weight for each index. With the final evaluation model, we can calculate the evaluation score combined with both the quantitative indexes and the qualitative indexes at once.

An accurate and reliable performance evaluation technique is indispensable for the development of marine antifouling coatings. The existing standard practice is however, based on the visual observation of biofouling settlement area, which is prone to the subjective judgment of the inspector. In spite of the above mentioned importance, a systematic and objective fouling evaluation technique has not yet been introduced. In this study, a novel quantitative antifouling performance evaluation method for marine antifouling paints is devised based on the image analysis of panel immersion test results. The present image analysis method is to quantify settlement area for each fouling category by distinctive color. The fouling categories are set as unfouled, biofilm, green algae, brown algae, calcareous animal and spongy animal with specific HSL (Hue, Saturation, Lightness) color ranges. In order to assess the effectiveness of the proposed method, static immersion tests for three antifouling coatings were undertaken for two years.

A quantitative performance evaluation of a robot teaching method using a force/moment direction sensor is presented. The performance of the teaching method using the force/moment direction sensor is compared with the conventional teaching pendant method. Two types of teaching tasks were designed and the teaching times required to complete the teaching tasks were measured and compared. Task A requires a teaching motion that involves four degrees of freedom motion. Task B requires a teaching motion that involves six degrees of freedom motion. It was found that, by using the force/moment direction sensor method, the teaching times were reduced by 25% for Task A and 45% for Task B compared to the teaching pendant method.

인공신경망을 이용해서 기존 곡을 학습시키고 새로운 곡을 생성하기 위해서는 전처리 과정으로 곡을 신경망이 인식할 수 있는 숫자로 변환해야 하며, 지금까지는 원-핫 인코딩이 사용되어 왔다. 본 논문에서는 음표 임베딩과 마디 임베딩을 제안하고 기존의 원-핫 인코딩과 성능을 비교하였다. 성능비교는 어떤 방식이 작곡가가 작곡한 곡과 유사한 곡을 생성하는지를 정량적 평가에 근거해서 수행하였으며, 평가방법으로는 자연어 처리 분야에서 사용되는 정량적 평가 방법들을 이용하였다. 평가결과 마디 임베딩으로 생성한 곡이 가장 좋았으며 그 다음으로 음표 임베딩이 좋았다. 이는 본 논문에서 제안한 음표 임베딩과 마디 임베딩이 원-핫 인코딩보다 작곡가가 작곡한 곡과 유사한 곡을 생성한 것으로서 의의가 있다.

Several factors can be chosen for evaluating seakeeping performance, such as deck wetness, propeller racing, slamming, rolling, vertical acceleration and vertical bending moment, in consi-deration of the safety of human being, cargo and ship. In fact, there are few developments for an evalua-tion method of seakeepting performance correponding with each ship's characteristics. The purpose of this paper is to develop an quantitative evaluation method of seakeeping performance according to ship types. The scope and the method of this study are as follow. (1) Obtain each response amplitude of ship's motion in waves by Ordinary Strip Method and apply it to short-crested, irregular wave for random process of the factors on seakeeping performance. (2) Define the evaluation index, the dangerousness, the maximum dangerousness and the evaluation diagram. (3) Figure out the different characteristics according to ship types by computer simulation of evaluating seakeeping performance. (4) Adopt vertical acceleration and one of rolling or lateral acceleration as the factors on seakeeping performance by clarifying the correlation of stochastic process. This study developed an evaluation method coincident with each ship's characteristics, and suggested a device for application to actual ship. This method might be useful in developing the practical system of seakeeping performance in accordance with ship types. The ship models for computer simulation are 175m container ship types, 93m tranning ship HANARA as passenger ship type, 259m bulk-carrier type and 164m pure car-carrier type.

In modern high performance engineering applications, the structural integrity of materials and structures are quite often evaluated using fracture mechanics. This evaluation in turn requires information on the flaw geometry (location, type, shape, size, and orientation). The ultrasonic nondestructive evaluation (NDE) method is one technique that is commonly used to provide such information. Flaw classification (determination of the flaw type ) and flaw sizing (prediction of the flaw shape, orientation and sizing parameters) are very important issues for quantitative ultrasonic NDE. In this paper new approaches to both classification and sizing of flaws are described together with extensive review of previous works on both topics. In the area of flaw classification, a methodology is developed which can solve classification problems using probabilistic neural networks, and in the area of flaw sizing, a time-of-flight equivalent (TOFE) sizing method is presented. The techniques proposed here are in a form that can be used directly in many practical applications to quantitative estimates of the flaw's significance.
