제시되는 시각 자극의 모호함에 따라 디자인 아이디어의 창의성이 어떻게 달라지는지 알아보기 위해 시각자극의 모호함의 세 가지 수준 (Vague, Ambiguous, Definite) 과 아이디어 교류 유무(Idea sharing Before & After)의 두 가지 수준으로 아이디어 스케치들을 구분하여 의사결정나무분석법을 시행하였다. 그리고 이를 통해 각 그룹의 아이디어 스케치의 창의성 예측점수와 그 예측점수에 영향을 끼친 변인은 무엇인지 그리고 그 기준은 어떠한지 살펴보았다. 분석 결과, 시각 자극의 모호함과 아이디어 교류의 유무에 따라 아이디어 스케치의 창의성 예측 점수가 높은 경우에 있어 중요한 영향을 미친 예측변수들은 종결저항, 독창성, 정교성, 추상성, 컨셉쌍 간의 유사도로 나타났다. 즉, 이 5가지 변수들은 유창성과 개념결합전략, 새 개념의 등장여부, 개인 창의력 지수, 창의적 문제해결성향보다 디자인 아이디어 스케치의 창의성에 더 연관이 있는 요인들임을 알 수 있었다. 그리고 아이디어 교류 후, Vague 자극을 제시 받은 집단이 창의성 예측값이 가장 높게 나타났고, 아이디어 교류 후, Definite 자극을 제시 받은 집단이 창의성 예측값이 가장 낮게 나타났다.

The present work proposes the potential fuzzy framework, based on fuzzy set theory, for supporting decision-making problems, especially, selection problems of a best design in the area of nuclear energy system. The framework proposed is composed of the hierarchical structure module, the assignment module, the fuzzification module, and the defuzzification module. In the structure module, the relationship among decision objectives, decision criteria, decision sub-criteria, and decision alternatives is hierarchically structured. In the assignment module, linguistic or rank scoring approach can be used to assign subjective and/or vague values to the decision analyst's judgment on decision variables. In the fuzzification module, fuzzy numbers are assigned to these values of decision variables. Using fuzzy arithmetic operations, for each alternative, fuzzy preference index as a fuzzy synthesis measure is obtained. In the defuzzification module, using one of methods ranking fuzzy numbers, these indices are defuzzified to overall utility values as a cardinality measure determining final scores. According these values, alternatives of interest are ranked and an optimal alternative is chosen. To illustrate the applicability of the framework proposed to selection problem, as a case example, the best option choice of four design options under five decision criteria for primary containment wall thickening around large penetrations in an advanced nuclear energy system is studied.

In this paper, we propose a fuzzy group decision making method for multiple decision maker-multiple objective programming problems to obtain the agreeable solution. In the proposed method, considering the vague nature of human subjective judgement it is assumed that each of multiple decision makers has a fuzzy goal for each of his/her own objective functions. After eliciting the membership functions from the decision makers for their fuzzy goals, total M-Pareto optimal solution concept is defined in membership spaces in order to deal with multiple decision maker-multiple objective programming problems. For generating a candidate of the agreeable solution which is total M-Pareto optimal, the extended weighted minimax problem is formulated and solved for some weighting vector which is specified by the decision makers in their subjective manner, Given the total M-Pareto optimal solution, each of the derision makers must either be satisfied with the current values of the membership functions, or update his/her weighting vector, However, in general, it seems to be very difficult to find the agreeable solution with which all of the decision makers are satisfied perfectly because of the conflicts between their membership functions. In the proposed method, each of the decision makers is requested to estimate the degree of satisfaction for the candidate of the agreeable solution. Using the estimated values or satisfaction of each of the decision makers, the core concept is desnfied, which is a set of undominated candidates. The interactive algorithm is developed to obtain the agreeable solution which satisfies core conditions.

As the basic study to investigate the mechanism of improvement in the dyeing fastness of natural dyes on silk fabrics the optical behavior of tannin solution, the optimal condition of tannin treatment and the changes of the physical structure of silk fabrics were studied in the treatment of tannin. Results obtained were as follows ; 1.The K/S values of tannin-treated silk fabrics were not changed by tannin content on silk fabrics but yellowing of tannin in treatment condition. 2. As the concentration of tannin was increased in its treating condition, the tannin content and K/S vague of tannin-treated silk fabrics were increased. 3. Because tannin gave rise to yellowing by hydrolysis and oxidation at high temperature, the higher tannin-treating temperature was, the lower the tannin content and K/S values of silk fabrics 4. The tannin content of silk fabric was higher in acidic treating condition and the highest K/S value was showed at pH 5. 5. As the tannin content of silk fabric was increased, the value of ζ -potential of it became negative. 6. As the tannin content of silk fabric was increased, the crystallinity and crystallite size of it were decreased. This meant that the fraction of amorphous region in the fibers increased. And the degree of orientation of it was decreased with the tannin treatment.

Cardiac surgery is generally followed by a period of routine ventilator support. When the patient seems hemodynamically stable and relatively alert following surgery, respiratory adequacy is tested by the weaning trial. In this study, physiological and clinical prediction of postoperative respiratory adequacy, including values of pulmonary function tests, were examined in an attempt to identity those few variables which predicted the outcome of the ventilator weaning trial following surgery. Our series comprised 27 patients who underwent elective open intracardiac operations at the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Kyungpook National University, from October 1979 to July, 1980. The pulmonary function tests performed on all patients included the following; forced vital capacity [FVC], forced expiratory volume [FEV1.0], forced expiratory flow [FEF 25--75~], residual volume [RV], and functional residual capacity [FRC], measured with a helium dilution technique. Of our 27 patients, 8 were successfully weaned within 20 hours of operation. All patients with cyanotic heart diseases or acquired heart diseases were unsuccessfully weaned. The bypass time in the successful weaning group was shorter in the mean value [82.8 minutes]than in the unsuccessful weaning group [120.5 minutes]. There was a relatively significant difference in the mean values for the two groups in arterial pressure, bleeding amounts and FiO2 among the postoperative monitoring variables, and in forced vital capacity [FVC]. The postoperative clinical assessments appeared vague but corresponded reasonably well to appraisal of success in weaning, especially in variables of cough and self-respiration efforts.

The non-linear least squares model(NLSM) has long been the standard technique used by hydrologists for constructing rating curves. The reasons for its adaptation are vague, and its appropriateness as a method of describing discharge measurement uncertainty has not been well investigated. It is shown in this paper that the classical method of NLSM can model only a very limited class of variance heterogeneity. Furthermore, this lack of flexibility often leads to unaccounted heteroscedasticity, resulting in dubious values for the rating curve parameters and estimated discharge. By introducing a heteroscedastic maximum likelihood model(HMLM), the variance heterogeneity is treated more generally. The maximum likelihood model stabilises the variance better than the NLSM approach, and thus is a more robust and appropriate way to fit a rating curve to a set of discharge measurements.

The pastiche is one of the most unique characteristics in the post-modern period. The pastiche fashion design is an intentional imitation expressed by deconstructivity of the design. It has become the major creation method of post-modern fashion by expressing the image from the variety and creativity. The concept of imitation in pastiche is the important fashion subject which lead the dynamics and creativities of fashion when It has freshness and spiritual energy. The values of creative area of pastiche are as fellows - firstly, it provides the delightness through the disharmony by being released from the restraint and stress of the restricted society. Secondly, the characteristics of restoration generated by development and reproduced from imitation has become an origin of creation. Thirdly, the boundary between subculture and high-class culture would be dismantled and the elements of these culture are mixed to become a unique image through its abundance and compromise vague public culture. Fourthly, the pastiche fashion dismantles the basic structure of clothes to endow avant-garde esthetic appreciation. Fifthly, the folklore fashion representing the culture of minority and neighboring countries would become a new destroying the historically fixed clue. sixthly, the reinterpretation of pastiche fashion discovers the new regulations and beauties from Imitation to provides tow Important elements of post-capitalism fashion, dynamics and creativity. Lastly the consistent adaptation of image of fashion design with strong technical and theoretical basis can establish new fashions of this era with its unique creativeness.

Ferroeletric LiNbO$_3$ thin films hale been prepared directly on Si(100) substrates by conventional RF magnetron spurttering system for nonvolatile memory applications. As-deposited films were performed RTA(Rapid Thermal Annealing) treatment in an oxygen atmosphere at 600 $^{\circ}C$ for 60 s. The rapid thermal annealed films were changed to poly-crystalline ferroelectric nature from amorphous of as-deposition. The resistivity of the ferroelectric LiNbO$_3$ film was increased from a typical vague of 1~2$\times$10$^{8}$ $\Omega$.cm before the annealing to about 1$\times$10$^{13}$ $\Omega$.cm at 500 kV/cm and reduce the interface state density of the LiNbO$_3$/Si(100) interface to about 1$\times$10$^{11}$ cm$^2$ . eV. Ferroelectric hysteresis measurements using a Sawyer-Tower circuit yielded remanent polarization (Pr) and coercive field (Ec) values of about 1.2 $\mu$C/cm$^2$ and 120 kV/cm, respectively.
