  • One of the significant problems in urban areas is lack of parking spaces. Therefore, maximizing the number of cars that can be parked in a given area becomes increasingly important as land costs increase. This paper presents a methodology of optimal parking lot design in relatively small areas. The discussion is limited to self-parking surface rectangular lots. The selection of stall dimensions and aisle widths is based on the regulations of parking lot design standards of Korea. A personal computer software, OPALD, was developed and implemented to design optimal parking lots. OPALD iterates angles of parking stalls from 45 to 90 degree, generates the combination of paring angles, and selects the best angles to fit the given area. A drawing data file is also generated to draw layouts of parking lots in the CAD pakage (AutoCAD). Application of OPALD shows good results to design parking lots in relatively small areas. By-products of this research represents the parking modules of various angles.

  • The design methodology of injection molding die has been changed from two-dimensional drafting to three-dimensional solid modeling, which is due to many advantages over the conventional methodology in terms of design modification and data associativity. In addition to the solid modeling capability, it is required for a mold designer to utilize a database management system that facilitates efficient mold design. In the paper presented is the implementation of a software program which automatically generates three-dimensional mold-bases including standard parts and slider parts, conforming to given geometric constraints. It is based on a commercial CAD system (Unigraphics NX) along with related API (application program interface) libraries. The research is expected to reduce design efforts and simplify construction of a complex three-dimensional mold-base model that is comprised of standard parts and slider parts, by use of the three-dimensional database and automatized geometric dimensioning.

  • SDAI (Standard Data Access Interface) is an interface specification of accessing various storage systems such as file systems and database management systems for STEP data. Using SDAI, both application program developers and CAD/CAM system developers can be relieved from dealing with STEP physical file or system dependent DBMS operations. In this paper, we present implementations of SDAI on different data models, i.e., relational, extended relational, and object-oriented. In order to implement SDAI, we need to translate the EXPRESS information model into target data models. The schema translation process for three different data models are compared and other implementation issues are discussed.

  • For the Korean fashion industry to become more competitive, not only does it need to develop a higher value-added fashion products, but also needs to raise creative and professional talented people. The purpose of this study is to propose ways to develop new curriculum for education in the fashion design field by analyzing the degree of recognition about the importance of curriculum in fashion design. Based on the curriculums of fashion design field of universities, a survey was conducted using a questionnaire to measure the degree of importance and the degree of application for the curriculum of fashion design field. The study gathered data from 235 students from 6 universities in Seoul. Major conclusions of the study are as follows: First, preferred career courses after graduation were fashion designer for woman's or menswear, patterner. Second, clothing construction field is considered to be the most important subject in the present, while material planning field is considered to become the most important in the future. The fashion design field was evaluated as an important field in the present and the future. Third, fashion design, accessory design, fashion design CAD, fashion illustration were evaluated as important subjects and highly available for career. Fourth, fashion design CAD, fashion illustration, and textile design were evaluated as the courses that needed more emphasis. Flat sketch, spec sheet, on-the-job training were needed to be included. Fashion designer, and patterner were preferred for career courses. Clothing construction, material planning, and fashion design were evaluated as important fields. Accessory design, fashion design CAD, and fashion illustration were evaluated as important and highly available subjects for career. For the new curriculum in the fashion design field, more courses on fashion design CAD, fashion illustration, textile design and on-the-job training are needed.

  • The construction industry from the research about materials calculate automation became accomplished plentifully. Material price calculate with application in the CAD plan is more quicker and accurate than with existing handy work. It gives a many effect in development of the research and estimation program against material calculate production automation with application of the CAD. But material calculate production uses an estimate program from generally a framework construction and the material calculate production work becomes accomplished. A thesis of the material calculate production methodology about a part of materials boundary condition from material calculate production work of framework construction is the actual condition which is insufficient. From the dissertation which it sees standardize the concrete, a concrete form a each part of materials calculate method from framework construction material calculate production. It standardize a part of materials agree with a condition of material calculate methodology which from a each part of materials boundary condition.

  • Virtual manufacturing is a technology facilitating effective development and agile manufacturing of products via sophisticated computer models representing physical and logical schema and behavior of real manufacturing systems including manufacturing resources, environments, and products. For the successful application of this technology, a virtual plant as a well-designed and integrated environment is essential fur sharing information and engineering collaboration among diverse engineering activities. The systematic approaches and effective methods for construction and application of a virtual plant are proposed in this paper, such as a 3-D CAD modeling, cell and line simulations, databases and some information technologies. Measuring and 3-D CAD modeling technologies of many equipments, facilities and structures of the building are developed, and effective information management system managing CAD models, related files and data is implemented in WWW environments. Finally, precise simulations of unit cell lines and the whole plant are performed. For the beginning of implementing a Virtual Automotive Plant, the Virtual Plant fur the Body Shop of a Korean automotive company is constructed and implemented. We could obtain the benefit of savings in time and cost in many manufacturing preparation activities in the new car development processes.

  • This study evaluated the efficacy and safety to determine the therapeutic responses of oclacitinib in canine atopic dermatitis (CAD) and identified factors related to the therapeutic response. Overall, 13 dogs with CAD were treated with oclacitinib for 56 days. Owners and veterinarians assessed visual analog scale (VAS) scores of pruritus and dermatitis. The examined dogs were grouped according to treatment success and failure based on changes in the VAS scores. To identify factors related to the therapeutic responses of oclacitinib, signalments (breed, sex, age, and body weight), mean progression time of CAD, mean Owner and Veterinarian VAS scores at day 0, and preexisting infection rate were compared between the two groups. Among the 13 dogs, 7 (53.8%) met the criteria of treatment success. In the success group, the Owner VAS scores were significantly lower from day 6 to 56 compared with the score at day 0 (P < 0.05). Additionally, the Veterinarian VAS scores were significantly decreased at days 14 and 42 compared with the score at day 0 (P < 0.05). There were no changes in hematological indices after the administration of oclacitinib. The most common abnormality reported was otitis externa (30.8%), followed by pyoderma (23.1%), and vomiting (7.7%). Factors related to responses of oclacitinib were not identified. This study demonstrated that oclacitinib was safe and moderately effective in dogs with CAD. This is the first report of the clinical application of oclacitinib in South Korea.
