This study investigated the design practice model based on the creative fashion designer's methodology in fashion education. 'The Design Cycle' was the criterion used to analyze the design method of Demna Gvasalia who is one of the outstanding contemporary designers. After that, this study's practice model was then developed and experimented to verify its effectiveness in design practice as based on Gvasalia's method where ready-to-wear products were firstly dissembled then re-constructed with new designs created based on re-constructed results. To test its effectiveness, a student oriented design workshop was held to extract design results through the practice model; in addition, the students also conducted a survey to evaluate the effectiveness of the method. According to the self-evaluation result, the participants generally accept the design efficiency through the distinctive process. An evaluation by three fashion experts was also conducted. Experts assessed that the model is recommendable for seniors having knowledges on 'Construction', it is appropriate to deal with the trickled-down copying trend that could promote student interest and generate separate results according to different visions. Therefore, it could be accepted that the applicability of this study's practice model was confirmed.

Traditional text-based system engineering, which has been used in the design and application of passive residual heat removal system (PRHRS) for lead-cooled fast reactors, is prone to several problems such as low development efficiency, long iteration cycles, and model ambiguity. This study aims to effectively address the abovementioned problems by adopting a model-based system engineering (MBSE) method, which has been preliminarily applied to meet the design requirements of a PRHRS. The design process has been implemented based on the preliminary design of the system architecture and consists of three stages: top-level requirement analysis, functional requirements analysis, and design requirements synthesis. The results of the top-level requirements analysis and the corresponding use case diagram can determine the requirements, top-level use cases, and scenario flow of the system. During the functional requirements analysis, the sequence, activity, and state machine diagrams are used to develop the system function model and provide early confirmation. By comparing these sequence diagrams, the requirements for omissions and inconsistencies can be effectively checked. In the design requirements synthesis stage, the Analytic Hierarchy Process is used to conduct preliminary trade-off calculations on the system architecture, after which a white box model is established during the system architecture design. Through these two steps, the analysis and design of the system architecture are ultimately achieved. The resulting system architecture ensures the consistency of the design requirements. Ultimately, a functional hazard analysis was conducted for a specific incident to validate case requirements and further refine the system architecture. Future research can further reduce the design risk, improve the design efficiency, and provide a practical reference for the design and optimization of PRHRS in digital lead-cooled fast reactors.

In the global ship structure and vibration analysis, the FE(finite element) analysis model is required in the early design stage before the 3D CAD model is defined. And the analysis model generation process is a time-consuming job and takes much more time than the engineering work itself. In particular, ship structure has too many associated structural members such as stringers, stiffness and girders etc. These structural members should be satisfied as the constraints in analysis modeling. Therefore it is necessary to support generation of analysis model with satisfying these constraints as an automatic manner. For the effective support of the global ship analysis modeling, a method to generate analysis model using initial design information within ship design process, that hull form offset data and compartment data, is developed. In order to easily handle initial design information and FE model information, flexible data structure is proposed. An automatic quadrilateral mesh generation algorithm using initial design information to satisfy the constraints imposed on the ship structure is also proposed. The proposed data structure and mesh generation algorithm are applied for the various type of vessels for the usability test. Through this test, we have verified the stability and usefulness of this system including mesh generation algorithm.

초기 디자인 단계에서 효율적인 디자인 의사결정을 위해서는 지오메트리에 대한 고려가 필수적이다. 하지만 중요한 의사결정은 지오메트리에 대한 효율적 분석이 가능한 BIM모델 보다는 여전히 대화나 물리적 모델, 제스처를 통해 이루어진다. 본 논문은 실시간 BIM분석을 위한 BIM 모델과 물리적 모델의 연동을 제안한다. 두 모델이 실시간으로 연결되는 시스템 프레임워크를 통해 건축가는 디자인 초기 단계에서 부터 BIM 모델을 효율적으로 활용할 수 있다. 이 프레임워크는 건축가들이 설계 초기 단계에서부터 마지막 단계까지 컴퓨터의 기술을 활용한 동적인 의사결정을 가능하게 한다.

This study attempts to integrate causal model with competitiveness evaluation model, both of which have developed independently of each other, in connection with many studies on PMES (performance measurement and evaluation system) including the BSC (balanced scorecard) of Kaplan and Norton (1992, 1996). For this attempt, this study is composed of four analyses : First, this study develops a structural model for evaluating and diagnosing corporate ‘comprehensive’ competitiveness including quality competitiveness, derive CCI (comprehensive competitiveness index) and QCI (quality competitiveness index) ; Second, this study analyzes the determinants of quality competitiveness, the impacts of quality competitiveness, on product design and product reliability, and the impacts of product design and product reliability on quality competitiveness in the comprehensive competitiveness evaluation model of this study. Third, this study empirically identifies the positioning of product design in the quality competitiveness evaluation model of this study and the functional relationship between product design and other functions : product development, manufacturing, marketing, and marketing, and sales in the same comprehensive competitiveness evaluation model, estimate the determinants of product design and its impacts, thereby providing some empirical findings for the foundation of design management theory, and Fourth, this study identifies the positioning of product reliability in the same quality competitiveness evaluation model, estimate the reliability function and the functional relationship between product reliability and other dimensions of product quality, and tests the hypotheses on the causality of product reliability.

The design process becomes more difficult due to the increasing complexity of products. Thus, without any proper design experience, designer cannot handle his design problems systematically. Besides, the conventional optimal design method cannot be used effectively at the early design stage, since most design problems must be formulated in terms of objective and constraint functions based on the mathematical concepts of Operation Research. Thus, in this paper, new design concept based on FBS (Function-Behavior-Structure) design model is introduced to help the novice designer formulate the complex design problems systematically into a mathematical form. In this FBS model, function means the designer's new intents designer wants to create for, structure stand for a final product configuration and behaviour is a product's performance. FBS design model is thus rather totally different concept used for formulating design problem, compared with conventional optimal design method. To validate this new FBS model, 330K VLCC design case is performed, and we found, though it is one design example case, that this new design concept could be effectively used for future ship design problems since, during the formulating design problem, the only engineering terminology such as function, structure, and behaviour of design product is used based on the engineering concepts, instead of mathematical terminology such as objective and constraints.

The purpose of this study is to develop the applied brassiere pattern of women which are fitting for 75A. The constructing of this experimental brassiere were lower cup, upper cup, front panel and U-wing as well as a full cup embcing the entire breasts. Basing on the bra model from domestic experiment results, development of an applied design, round side type pattern, has been suggested. Thus, suggesting the round variation design bra, which is an applied design based on the basic model based on the breast volume. Based on the sizes that are in reference to Size Korea (2004) and related previous researches, the basic model that has been experimented with 11.4% polyurethane and 88.6% Nylon as the materials, has been selected as the model of research. This takes 75A, the size of which is set according to the underbust circumference and the breasts circumference, as the basic model. It is an application in terms of design, and there is no change to the cup volume or size because it has been moved only from the cutting line. The applied design changes the right side of the lower cup into an easily-movable form and attaches it to the upper cup, and the lower cup takes the right part of the upper cup to form a cup shape of round variation design. It also changes basic straight form of the wings, and alters them into U-shape.

본 연구에서는 기존에 이용되었던 디자인 프로세스의 실증적 단점들을 극복할 수 있는 소비자 지향적인 방법론을 제안하였다. 즉, 기존의 디자이너 직관에 의한 디자인 속성 도출 방법과는 다르게, 디자인 속성을 규명하지 않은 상태에서 소비자들이 선호하는 제품의 중요 디자인 속성을 추출해 내는 소비자 관점의 디자인 속성 도출방법을 제시하였다. 실증분석에서는 구체적인 속성 규명을 요구하지 않는 PRETREE 모형을 활용하여 유무선 전화기를 대상으로 소비자 선호 기반 중요 디자인 속성을 도출하고 그 시사점을 제시하였다. PRETREE 모형은 심리학, 소비자학, 경영학분야에서 널리 활용되어 왔던 소비자 선택모형으로, 디자인분야에서도 주관적으로 치우칠 수 있는 디자인 평가를 계량화할 수 있는 새로운 분석방법으로 활용될 수 있을 것으로 기대된다.
