  • This study aims to focus on clothing design's practical uses of the superior esthetic elements that can be found among the East's representations, in particular the characteristic Korean elements found in the latter part of the Chosun Era's women's Gauche and decorative personal ornamentation's moulded features. This has been the foundation for the creation of all eight pieces, and the conclusion is as follows: First of all, the Chosun Dynasty women's Gauche and ornamentation are in close relation to the general flow of society at the time. Gauche and personal ornamentation was not just a matter of beauty consciousness, but is permeated with then-mainstream society's culture, the results of an attempt to display a Korean appearance. Secondly, the desirability of the Chosun women's hair was expressed through Gauche, and through the exceptional brilliance of a diversity of embroidered color tones, braided as though creating Dare. Using this technique in clothing, a new image was created. Thirdly, the outstanding beauty of personal ornamentation's mouldings was used while creating new clothing compositions. The beauty felt through the Chosun women's personal ornamentation can also be felt through today's clothing. More than merely practical, this beauty also brings one closer to Korea and Korean past.

  • Secondary batteries with high performance are essential in widespread use of modern portable devices such as cellular phones and laptop computers. High energy density, long cycle life, and safety are some of important requirements for secondary battery. To achieve such characteristics, a mixing proportion of electrolyte solution ingredients in the battery should be carefully chosen. In this paper, using statistical design of mixture experiments (DOME), we attempt to find an optimum condition of designing the secondary battery. DOME has a distinct feature in that the experimental region is represented by simplex, rather than hypercube, because the sum of blend proportions should be unity. Several designs based upon this point have been proposed for mixture experiments. Among them, an extreme vertices design is employed in this paper because there are a couple of blend constraints to be considered. In order to investigate how the mixing proportion interacts with other manufacturing factors, a fractional factorial design is also included across the extreme vertices design. As a result, we find that the blend proportion of solution ingredients has a significant effect on battery performances. By simultaneously optimizing two battery capacities, this paper proposes an optimum blend proportion according to process factor settings.

  • The paper deals with the development of a model for group decision making under multiple criteria. The Multi-criteria group decision making (MCGDM) is the process to determine the best compromise solution in a set of competing alternatives that are evaluated by decision makers having their own preferences on conflicting objectives. For MCGDM, we propose a Mixed-Integer Programming (MIP) model that implements a revised median approach by noticing that the original median approach cannot consider the willingness to reject and the indifferent preference conditions. The proposed MIP model tries to select a common best Pareto-optimal solution by maximizing the overall desirability considering the willingness to reject and the indifferent preference that represent the tolerance measure of each decision maker. To evaluate the effectiveness of the proposed model, we compared the results of the proposed model with those of the median approach. The results showed that the proposed MIP model produces more realistic and better compromised alternative by incorporating the decision maker's willingness to reject and the indifferent preferences over each criteria.

  • Recently, in organizations many decisions are being made by groups. And the organization is changing a lot so are groups. To help decision making of changing groups, we need more flexible and more adaptive GDSS. Therefore one of the critical success factors of GDSS is flexibility and incremental improvement. Prior research on specifying design requirements of GDSS suggests generic design requirements. But they are too general to be incorporated directly into system design, because of the disparity between real group and ideal group that the researchers studied. Many design strategies that start from the generic design requirements thus have contingency variables that changes as the characteristics of group change. From the viewpoint of developers, these variables implicate the desirability of flexibility. To achieve flexibility we need new methodology of design and implementation. Nowadays, object-oriented analysis and design methodologies have been progressed to the point that many systems are being developed through these methodologies. In this paper, a design is proposed using Object-Oriented Modeling Techniques(OMT). Exploiting object-oriented paradigm results in a highly flexible and easily upgradable design.

  • Due to the environmental problem, automotive companies are trying to reduce the weight of car body. Therefore, WP(Transformation Induced Plasticity) steels, which are hish strength and ductility have been developed. The application of TRIP steel to the members has been reported to increase the energy absorption capability. Welding process is a complex process; therefore deciding the optimal welding conditions is an effective method on the basis of the experimental data. However, using a trial-and-error method from the beginning in such a wide area, in order to decide the optimal conditions requires too many numbers of experiments. To overcome these problems and to decide the optimal conditions, response surface methodology was used. Response surface methodology is a collection of mathematical and statistical techniques that are for the modeling and analysis of problems in which a response of interest is influenced by several variables and the objective is to optimize this response. The introduced method was applied to the resistance spot welding process of the TRIP steel and the welding parameters were optimized. (Received December 6, 2002)

  • The UNCITRAL, during its thirty-two session in 1999 discussed certain issues and problems identified in interactional commercial arbitration practice. The issues discussed include certain aspects if conciliation proceedings ; the legislative requirement of a written form for the arbitration agreement ; arbitability ; soverign immunity ; consolidation of more than one case into one arbitral proceedings ; confidentiality of information in arbitral proceedings ; rasing claims in arbitral proceedings for the purpose of set-off ; decisions by "turncated" arbitral tribunals liability of arbitrators ; power by the arbitral tribunal to award interest ; costs of arbitral proceedings ; enforceability of interim measures of protection ; and discretion to enforce an award that has been set aside in the state of origin. Among those issues discussed, most of States agreed that the issues relating to certain aspects of conciliation proceedings ; the legislative requirement of a written form for the arbitration agreement ; enforceability of interim measures of protection ; and discretion to enforce an award that has been set aside in the State of origin should have priority over other issues. The UNCITRAL may wish to consider the desirability of preparing uniform provisions on any of those issues, possibly indicating whether further work should be towards a legislative text (such as a model legislative provision or a treaty) or a non-legislative text (such as a model contractual rule).

  • The conventional development of multi-component electrodes is based on the researcher's experience and is based on trial and error. Therefore, there is a need for a scientific method to reduce the time and economic losses thereof and systematize the mixing of electrode components. In this study, we use design of mixture experiments (DOME)- in particular a simplex lattice design with Design Expert program- to attempt to find an optimum mixing ratio for a three-component electrode for the high RNO degradation; RNO is an indictor of OH radical formation. The experiment included 12 experimental points with 2 center replicates for 3 different independent variables (with the molar ratio of Ru, Ti, Ir). As the Prob > F value of the 'Quadratic' model is 0.0026, the secondary model was found to be suitable. Applying the molar ratio of the electrode components to the corrected response model results is an RNO removal efficiency (%) = 59.89 × [Ru] + 9.78 × [Ti] + 67.03 × [Ir] + 66.38 × [Ru] × [Ir] + 132.86 × [Ti] × [Ir]. The R2 value of the equation is 0.9374 after the error term is excluded. The optimized formulation of the ternary electrode for an high RNO degradation was acquired when the molar ratio of Ru 0.100, Ti 0.200, Ir 0.700 (desirability d value, 1).

  • To optimize the mixing ratio of ingredients to obtain the best sensory qualities, a response surface methodology with a central composite design was performed on hot water extracts using crucian carp Carassius carassius treated with diluted vinegar (pH 5.24-5.30). The optimal solutions for four parameters (overall acceptability, odor, flavor, and taste) were obtained using the second-order response surface regression models. The optimal formulation appeared to be 124.15 g of ginger and 96.09 g of garlic with 1 kg of ground crucian carp meat based on the desirability function technique.

  • 생선 어묵에 대두분리단백질, 난백, 유청단백질, 글르우텐과 같은 단백질들을 첨가하였을 때 그들이 어묵의 조직감을 수사하는 기능이 평가되었다. 단백질들은 어묵의 강도, 경도와 층밀림성을 감소시켰다. 단백질이 첨가된 어묵제품은 관능검사에서 제품의 질김성, 씹힘성 및 경도에 대한 강도는 감소시켜주는 반면 이들에 대한 종합적 기호도는 증가시키는 것으로 나타났다. 첨가제로 사용하였던 단백질 자체로 만든 겔의 강도는 이들 단백질을 첨가하여 만든 어묵의 겔 강도와 역비례 관계를 나타냈으며, 첨가한 단백질들이 어묵의 조직감을 수사하는 기능적 특성은 각 단백질들의 수화능력과 겔화 특성 등에 기인하는 것으로 나타났다.

  • The quality properties of Jeung-pyun made with soybean protein isolate(SPI) were investigated. The SPI Jeung-pyun was manufactured using 3% whole protein, 7S protein or 11S protein(w/w). The redness values (a-values) of the Jeung-pyun were negative and the yellowness(b-value) of the control group was significantly lower compared to the other samples. The textural characteristics of the Jeung-pyun were influenced by the additions of SPI. The Jeung-pyuns containing soybean flour, whole protein, 7S and 11S protein had increases in springiness, but decreases in cohesiveness. In the sensory evaluation, overall desirability, sweetness, and moistness were highest in the whole protein group. The control group showed the highest scores for hardness and toughness, and the scores for after-taste and adhesiveness were the highest in the samples made with soybean flour. The 7S and 11S additions showed high scores in terms of color and springiness. In the analyses for consumer acceptance and sensory quality intensity, the whole protein addition had significantly higher scores for general acceptability and the Makgeolli flavor. Hardness was highest for the control group and the Makgeolli flavor was strongest with the soybean flour addition.
