Producing tools for actively meeting social needs in a radical changing society due to the development of modern technology has been shifted from physical ability to intelligent ability. The prominence of educating creativity is perceived as a good preparation in order to deal with them. Considered that assessment which is systematic activity to collect, analyze, diagnose, and judge information of a series of instruction practices is means to impart evidence and feedback of teaching learning practices, education and assessment is placed on reciprocal relationship. Nevertheless, there has been some tendency of neglect of assessment, comparing education for upbringing creativity. In this paper model of pencil and paper problem is discussed focusing on the sub-components of creativity and problem solving as one of the variety of means to extend mathematical creativity.

The purpose of this study is to develop and evaluate a social competence enrichment program for institutionalized children in early childhood. The program was developed to enhance institutionalized children's social competence. The program consists of sixteen 30-minute sessions. 19 institutionalized children (11 boys and 8 girls) participated in this program. The effect of this program was evaluated by institutionalized preschool children's emotional knowledge and interpersonal problem solving strategy. Assessment of emotional knowledge consists of identification and situation task. Interpersonal problem solving strategy includes forceful, prosocial, and manipulative strategy. Results showed that there was a significant experimental effect for emotional knowledge. Experimental children showed higher scores of emotional knowledge than control children. Also, there was a significant experimental effect for prosocial and forceful strategy. Experimental children showed higher ratio of prosocial strategy and lower ratio of forceful strategy than control children. The results of program evaluation revealed that this program was helpful for promoting institutionalized children's social competence.

In this paper, a method to apply the simulated annealing method to three dimensional layout design problem which has multiple constraint conditions and evaluation criteria, was suggested. A program to support three dimensional layout design was developed according to the suggested method. This program was applied to the layout design of the wireless unmaned ocean space submergible boat. The layout result was improved 19.0% for the result of layout design expert. By this, it was verified that the suggested method has validity in supporting three dimensional layout design problem.

In order to design a stable robust controller, nominal model, and the upper bound about the uncertainty which is the error of the model are needed. The problem to estimate the nominal model of controlled system and the upper bound of uncertainty at the same time is called robust identification. When the nominal model of controlled system and the upper bound of uncertainty in relation to robust identification are given, the evaluation of the validity of the model and the upper bound makes it possible to distinguish whether there is a model which explains observation data including disturbance among the model set. This paper suggests a method to identity the uncertainty which removes disturbance and expounds observation data by giving a probable postulation and plural data set to disturbance. It also examines the suggested method through a numerical computation simulation and validates its effectiveness.

The purpose of this study was to measure consumption values and to investigate the differences in the process of decision making when purchasing apparel products among groups divided by consumption values. A self-administered questionnaire was distributed to 550 subjects in their 20's and 30's from Sepember 29th to October 25th in 2001; 463 were used for the data analysis. The results of this study were as follows; Consumption values were classified into five factors: Practical/functional value, Social/conformitive value, Subjective/aesthetic value, Epistemic value and Conspicuous value. Subjects were classified into 4 groups based on consumption values: the Conspicuous, the Epistemic, the Social/conformitive and the Indifferent. There were significant differences among the four groups in selected motives in the problem recognition process. Significant differences were found among the groups in own taste & personality in the information search process. Significant difference were also found in the importance of design, color, price, coordination, fashion and self-image in the alternative evaluation process.

It has been well known that infertile women experience not only emotional disturbance but also stress. But there is no concern about male infertility patients. So phychiatric symptoms were studied with SCL-90 (Symptom Check List-90) in 30 infertile men who was operated testicular sperm extraction (TESE) in Samsung Cheil Hospital and in age matched 31 fertile men from Jan. 1998 to Aug. 1998. In 5 symptom dimensions (Obcessive-Compulsive, Interpersonal Sensitivity, Depression, Phobic anxiety, Psychoticisim) scores. The Infertile group scored significantly higher than the control group. The result revealed that infertile men also experienced substantially more psychiatric symptoms than fertile men. Considering this results, psychiatric evaluation and tender care by infertility specialist are necessary for infertile men during and after evaluation and treatment.

Environmental pollution has become a serious worldwide problem the humans has encountered in several decades. On the respect of the preservation of the global environment, world-wide consensus to cope with this problem was represented as 1992's Rio Declation. The purpose of this study is to develope evaluation technique of ecological architecture. The environmental scores of the buildings are evaluated and improved from the building design phase in order to build the best environmental building. Ecological architecture is mainly based on the balance of three element : Nature, Humanity, and Cost saving. Its main goals are energy saving and recycling, resource saving, high contact with circumstances, and health & amenity.

Large bias errors which occur during a numerical evaluation of the Rayleigh's integral is not due to the replicated source problem but due to the coincidence of singularities of the Green's function and the sampling points in Fourier domain. We found that there is no replicated source problem in evaluating the Rayleigh's integral numerically by the reason of the periodic assumption of the input sequence in Dn or by the periodic sampling of the Green's function in the Fourier domain. The wrap around error is not due to an overlap of the individual adjacent sources but berallse of the undersampling of the Green's function in the frequency domain. The replicated and overlApped one is inverse Fourier transformed Green's function rather than the source function.

본 논문에서는 MLP신경망의 패턴 학습과정을 위하여 시공간 병렬성을 고려한 병렬처리모델을 제시한다. 시간 병렬성을 위한 학습집합 분할과 공간 병렬성을 위한 네트워크 분할을 동시 적용하여 융통성있는 병렬처리모델을 설계하고자 하였다. 성능평가모델로부터 해석적으로 구한 결과, 대규모 과제라고 해도 패턴 크기와 패턴 갯수 중 어느 쪽이 지배적이냐에 따라 분할병렬처리 방법이 절충되어야 할 것으로 본다.

The conventional way to acquire sufficient amount of daylight in interiors is to provide large openings with clear glass. The use of clear glass on the whole facade, however, might cause a sort of visual problem because of the harness of direct sun and brighter sky surface than expected. They should be filtered in opticalway or bounced in the architectural. One of the common solutions for the problem might be the use of photometric glasses with various transmittances for the glass walls. This paper deals with performance data related to the impact of various transmittal glazing materials for window systems in terms of daylighting. A series of scale model measurements was carried out with the fundamental configuration of a commonly used all-glass facades. Additionally some experimental performance index was issued for the better expression of the need of natural lighting.
