인간은 어떤 대상을 인지해 나가는 과정에서 심성모형을 이용해 보다 효율적으로 정보처리 한다. 만약 어떤 대상을 이해해 가는 과정에서 그들이 사용하고 있는 심성모형이 어떤 것인지를 알 수 있다면 그것을 어떻게 인지할 것인지를 우리는 알 수 있을 것이다. 마찬가지로 시각물을 인지하는데도 심성모형이 사용되고 있을까\ulcorner 만약 이것이 사실이라면 우리는 새로운 디자인물을 사용자가 어떻게 이해할것인지를 분석할 수 있을 것이다. 본 연구에서는 이와같은 목적으로 인간이 시각적 심성모형을 통해 새로운 대상을 이해하는지를 알기 위해 2000cc급 자동차 측면을 자극재료로 하여 A집단에는 100%의 예비자극을 보여준 후 120%로 늘려진 실험자극을 보여줬고, B집단에는 120%의 실험자극만을 보여 주는 실험을 하였다. 실험결과 A집단이 B집단보다 실험자극을 보다 길게 지각할 것이라는 연구가설이 통계적으로 유의미한 것으로 밝혀졌다. 따라서 인간이 시각물을 지각하는데 에도 심성모형을 사용한다는 것이 증명되었으며, 이와같은 결론이 산업디자인분야에 시사하는 바는 어떤 대상을 디자인하는데 소비자가 생각하고 있는 기존제품의 시각적 심성모형을 알면 새로이 제시하려는 디자인대안에 대한 정화한 이해를 할 수 있게 된다는 것이다.

Because of the specificity of subjects belong to middle school curriculum of Home Economics Education of function training is very important. but it pointed out that the existing standards are out-dated, and because of it , it incongruent to our realities. Therefore, whenever the curriculum o education and the national textbook are reorgrnized periodically, the reform of standards of educational materials & facilities must be followed by it. But in my opinion, in korean middle school, especially in Home Economics Education, educational facilities are not reformed at a proper time. Therefore to enhance the qualities of experimentation/practice of Home Economics Education, in the first place, the preparation for the given conditions of standards of educational materials & facilities are needed. But the educational facilities of Home Economics Education have many problem not only in the qualitative aspect but also in the quantitative aspect. And in addition to it, lost of educational facilities which cannot match contents of national textbook of Home Economics Education are exist. Therefore this thesis aims at examining comprehensively the problem of experimentation /practice of experimental materials & facilities of Home Economics Education connect with contents of Home Economics Education, holding several problems of experimentation/practice of Home Economics Education in middle school, grouping ; the principles and ways concerning the innovation experimental materials & facilities of Home Economics Education by which many teachers and students make sure of more efficient teaching/studying, and obtaining basic data which guarantee the ability of innovation concerning problems of the education of experimentation/practice of Home Economics Education. Method are : 1)grasp our educational realities with my original(question). 2)Integrate/analyse results of 1) 3)check the frequency, percentage with methods of X$^2$-test, T-test, and ‘One-way Analysis of Variances’. 4)suggest my own alternative proposal.

In this paper, we present the experimentation and demonstration results of Korea-Japan high-speed satellite ATM network using Ka-band Koreasat-3. This experimentation consists of two items - TCP/IP and MPEG-2 video/audio transmission over 155Mbps ATM based satellite network. The goals of this experimentation are to measure TCP performance when the only standard mechanisms approved by IETF in order to improve TCP performance in LFN(long fat network) are used and to derive the effects of quality for the high definition video stream when MPEG-2 TS is transmitted through 155Mbps satellite ATM link. With on the results of the experiments, we demonstrated the applications suitable to the high-speed satellite ATM network. The first TCP/IP and MPEG-2 transmission experiments were done at the rate of 155Mbps using Ka-band KOREASAT-3 between Korea and Japan, and its results will be demonstrated with the ATM-based 3D-HDV(3 dimensional High definition video) and HDTV during 2002 Korea-Japan World Cup Soccer Game.

The characteristics of light in the paintings of Rembrandt van Rijn, Johaness Vermeer and Edward Hopper are very different. While Rembrandt and Vermeer lived in the 17th century, Hopper lived in the 20th century. Although this time gap, comparative study on their light-space relationship is important because there are spatial similarities as well as light differences. Most three painters' works depict interior spaces with one person inside. The interior space is filled with different light and shadow. In the Rembrandt's paintings, only part of the figure is lit in the ambiguous darkness. In the Vermeer's paintings, the soft indirect light is filled in the domestic space and the boundary between the figure and space is blurred. In the Hopper's paintings, the direct sunlight invades the interior and the figure confronts with strong daylight. These light differences were caused by the artists' intentions as well as the environmental situations. 4 case paintings of each artist were analyzed by phenomenological aspects and computerized light brightness test. Scale models were built to re-construct the three different light characteristics. The model experimentation will have potential to develop 2 dimensional art analysis into 3 dimensional space design by means of light. However it was very difficult to construct the three lights, the experimentation shows they have unique characteristics that can be applied to spatial design studies.

이 연구는 중등 화학 교사 전문성 및 지향점 제공을 위한 기초 조사로서, 실험 수업을 성공적으로 진행하기 위하여 필요한 화학 교사의 실험 능력에 대한 규명을 목적으로 하였다. 문헌 연구, 교과서 실험 분석, 과학 교사 설문 조사의 결과에 기초한 연구팀의 지속적인 논의를 통하여 연구를 진행하였다. 화학 교사의 실험 능력 규명을 위하여 수집된 자료들을 정리하여 크게 네 개의 단계(실험 수업 준비, 실험 수행 및 정리, 실험실 관리, 실험실 안전 관리)로 나누고, 각 단계별로 실험 능력에 관련된 소영역과 세부 내용 요소를 선별 ․ 수정하여 재배치하였다. 실험실 안전 관리는 실험실 및 실험 활동에서 ‘안전’의 중요성을 강조하기 위해 별도의 단계로 구분하였다. 화학 교사가 갖추어야 할 실험 능력은 실험 수업 지도를 전제로 하여 교사 스스로 실험 수행을 할 수 있는가에 대한 능력으로, 시약 및 측정기기 사용, 시료 준비, 실험 설계, 바른 실험 습관 및 숙련도, 자료 정리, 분석 및 추론, 그리고 실험실 관리 및 실험실 안전 관리에 관련된 능력으로 특정지어 질 수 있다.

Every year, the last products from most important builders of high bandwidth digitizers are tested in our laboratory which is specialized in the design and the characterization of fast links used in large laser facility. The purpose of this article is to describe the series of tests conducted during the characterization of such digitizers. More particularly, it takes an interest in the metrology of instruments with more than 5 GHz of bandwidth. It presents the different methods used and the kind of conclusion that we can give after such study. Such metrology campaign which usually takes one month of work, allows us to observe the smallest details and characteristics that usually builders don't give in their tables specifications. After the campaign, a copy of our technical report is written and sends to the builder. This report can be used by the technical team to ameliorate the points we noted.

This work is conducted with the aim of using waste material to reserve the natural resources. The objective is accomplished by conducting experimentation and verify by modeling based on fuzzy logic. In experimentation, concrete is casted by using natural/river sand as fine aggregate and termed as control specimen. Natural sand is conserved by replacing it with used foundry sand (UFS) by an amount of 10, 20 and 30% by weight. Fresh and hardened properties of concrete are investigated at different ages. It is observed that compressive strength and modulus of elasticity reduced with the increase in amount of UFS. Furthermore, concrete compressive strength is predicted by using fuzzy logic model and verified at different replacement ratio and age with experimental observations.

It is unpractical for the optimal design theory based on the given model and assumption to be applied to the real-world experimentation. Particularly, when the experimenter feels it necessary to consider multiple objectives in experimentation, its modified version of optimality criteria is indeed desired. The constrained optimal design is one of many methods developed in this context. But when the number of constraints exceeds two, there always exists a problem in specifying the lower limit for the efficiencies of the constraints because the “infeasible solution” issue arises very quickly. In this paper, we developed a sequential approach to tackle this problem assuming that all the constraints can be ranked in terms of importance. This approach has been applied to the polynomial regression model.
