The multiobjective optimization is presented for the optimal design of induction motors. The aim of design is to find an optimized induction motor in terms of both the efficiency and the mass. The efficiency and the mass are linearly combined using the weighting factors. Optimization process is performed by using the improved (1+1) evolution strategy (ES). ES is the algorithm that can find the global minimum. To verify the validity of the proposed method. the method is applied to a sample design.

In this paper, an adaptive optimization strategy utilizing Kriging model and genetic algorithm is proposed for the optimal design of electromagnetic devices. The ordinary Kriging assisted by the spherical covariance model is used to construct surrogate models. In order to improve the computational efficiency, the adaptive uniform sampling strategy is applied to generate sampling points in design space. Through several iterations and gradual refinement process, the global optimal point can be found by genetic algorithm. The proposed algorithm is validated by application to the optimal design of a switched reluctance motor, where the stator pole face and shape of pole shoe attached to the lateral face of the rotor pole are optimized to reduce the torque ripple.

The growth of domestic fashion industry market went sluggish affected by long-term slow growth and shrinking consumer sentiment since 2012, and the entire market has shown a slight growth since 2017. Yet only some conglomerates or global businesses experience this growth. Small and medium-sized fashion companies or rising fashion designers in South Korea, face real limitations and problems poor capital, lack of professional workforce, experience, information and educational opportunity as well as difficulty of acquiring distribution network, which lead to further polarization between conglomerates and small businesses. Thus, this study proposed mobile virtual viewer system-based collaborative application prototype capable of overcoming limitations and problems drawn by analyzing business environment of domestic brands launched by rising fashion designers. Especially, through applied template-based 3D virtual fashion design technology and performing the entire process in the virtual reality beyond spatial and temporal restraints, it is assumed that more effective and efficient outcomes can be obtained compared to the previous method.

The purpose of this study was to develop a new Korean fashion design using forced-relationship techniques and the traditional hanbok Korean dress and Korean traditional images as the source of the ideas. The research methods consisted of literature research and design production. In the literature research for the hanbok composition and design elements, the concept and type of forced-relationship techniques were studied. The design development process was as follows. First, 'Developing a Korean fashion design' was set as the design theme. Second, the composition and design elements of hanbok and Korean motifs, which consist of Korean images were set as fixed elements of the forced-relationship technique. Third, among the various trends in keywords, 'punk' belonging to a subculture, was set as an arbitrary element of the forced-relationship technique. Fourth, the punk fashion design elements and items were listed. Fifth, a rough sketch was performed by selectively combining fixed and arbitrary elements. Sixth, a design evaluation process was conducted to select the designs out of 52 design sketches that fit the purpose of the study. Seventh, a total of six designs were selected after making design modifications. Through this, a total of six works of women's clothing was designed, made, and presented. This study offers the possibility of developing new Korean fashion design images, and a chance to share designs based on different cultural elements in the global market.

This paper presents requirements for workflow management systems supporting CITIS. We propose an architecture of global workflow management system which aims at supporting external workflow among different organizations rather than internal one. The architecture consists of five key elements, that is process definition language, process graphic design tool, control engine, status monitoring tool, and interface models. For each of these elements, implementation requirements are presented and its major functions are described. A key concept to the CITIS standard is the integration of disparate systems in distributed environment. This leads us to place a special emphasis on the interface models that can enhance the interoperability between externally participating workflow systems. Two interface models for the global workflow management system are explained. CORBA, the most widely accepted standard for distributed object management, can be adopted to facilitate the integration. World Wide Web can be used for the underlying platform on which information is exchanged and the status of processes instances is monitored. The workflow management system can provide a ready and easy access to and management of the data for CALS environments.

Purpose - This paper aims to review cold chain management, especially in the pharmaceutical industry, to explore the cold chain process of delivering temperature-sensitive pharmaceutical products, and to identify areas for further development. Research design, data, and methodology - The paper, based on literature review and corporate analysis, reviews the development and status of the cold supply chain system, including its important role in the pharmaceutical industry. Results - Logistics in this field requires more stages than are typically needed. Due to the unique characteristics of the market, few companies can provide the services; currently, only few global companies with large networks and high technologies can afford to do so. Expanding pharmaceutical markets to meet global demand will require cold chain development, especially in "pharmerging" markets. Conclusions - Cold chain is a highly sensitive market in terms of products being carried within the chain that itself is a complex system. However, at the same time, it is a niche market with new opportunities. Hence, a sound cold chain infrastructure is needed to satisfy companies, governments, and customers for both commercial and public reasons.

The purpose of this paper is to design a survey of passenger satisfaction by using the Likert five-scale for the passengers of Incheon International Airport and Beijing Capital International Airport in China, and to combine the actual service situation of the airports in the two countries, using SPSS statistical software. Analyze and process statistics. Using the questionnaire survey method and exploratory factor analysis method, the airport service quality is analyzed to analyze the impact model of customer satisfaction. We will sort out the customer satisfaction with the two airports, compare and analyze the gaps in airport services between the two countries, and identify problems to formulate optimization and improvement plans.

세라믹 사출공정(CIM)은 산업 분야 전반에 걸쳐 널리 사용되고 있는 공정 중 하나로, 점차 의료용 전자기기의 부품 등으로 확대 적용되고 있다. 본 연구에서는 FEM 해석을 통해 CIM의 공정변수가 제품의 품질에 미치는 영향을 분석했다. 단순평판 형상의 해석결과를 기초로 구멍이 있는 형상, 모서리부가 둥근 형상 및 측벽 구조가 있는 형상 등과 비교 분석했다. 구멍이 있는 형상의 경우, 구멍 주변에 밀도분포가 고르지 못하며 용접선(weld-line)과 같은 결함이 발생할 수 있음을 예측할 수 있었다. 반면 제품의 모서리부 반경이 크면 성형성 및 유동성이 좋아지는 것을 확인했다. 따라서 CIM 공정변수 뿐만 아니라 제품의 형상변수도 고려해야 한다. 해석결과 온도, 초기분율, 속도 등의 공정변수는 제품의 품질 향상을 위한 중요한 설계 변수가 될 수 있음을 확인할 수 있었다.
