  • This Paper makes an attempt to suggest a process of automatically generating application software based on the Entity-Relationship model 1. The designer develops an E-R model of an real-world system. 2. The designer inputs the entity and relationship types, and attributes shown in the E-R model, and also the basic operations of the application system to the software generator. 3. The application generator produces database schema and link information between application programs, and then automatically generates a stereo-type application system. In order for the automated application generator to build the application system in a systematic way, four basic program generation rules have been suggested. A set of computer programs have been developed in order to show the applicability of the automated software generation process suggested in this paper. By following each rule with the generator, the designer can build an application in an efficient manner compared with traditional (manual programming) approaches. It has been demonstrated from the case study that the idea of applying an automated generator in systems development based upon the E-R model is feasible.

  • An optimal process design of a foreign protein production system was carried out using a bioprocess flowsheeting software, BioPro Designer, with a capability of economic analysis. The flowsheeting program was applied to a production system of the tailspike protein of Salmonella phage P22, and helped save time and efforts in selecting an optimal process. A wild type tailspike and two types of mutant tailspikes, tsf G244\longrightarrow,R and Su A334\longrightarrowV, were considered in this study to show that the folding characteristics of foreign protein produced inside host influenced the selection of the best production system. An optimal production system for mature tailspike was chosen under the criterion of capital investment per unit mass of mature protein recovered.

  • This study attempted to extract and structure the job skills required for 3D designers, which have been recently introduced to the fashion industry. The study aimed to materialize and objectify the 3D designer's job, using a focus group interview for the survey. The 3D designer has the TD task of making 3D virtual samples using the pattern files developed in Pattern CAD. Graphic design and fabric digitization are also major tasks for the 3D designer. CLO is mainly used for 3D virtual sample production, and PixPlant, Substance, Photoshop, Cinema 4D, Daz studio, and 3ds MAX are used for image and avatar editing. As per the job skills required for 3D design work, basic knowledge about patterns and sewing, skill in 3D virtual clothing technology, ability to use various software, and English skills were considered important, in that order. In particular, the need for knowledge about patterns and sewing became more important than the skill in 3D virtual clothing technology itself. To train 3D designers, it was found that not only 3D virtual clothing software, but also education on patterns and clothing construction, CAD developer's curriculum certification system, and 3D designer qualification management were required. In addition, 3D designers are recognized as an essential job in fashion vendors, and the demand for domestic brands is increasing. The biggest limitation of the 3D virtual clothing system is the perfection of the digital fabric. Also, technical improvement is needed.

  • The web-based project is seriously not efficient area at software engineering. In order to develop a web-based system, UI(User Interface) designers usually first design display layout and then business logic developers bring to complete the coding of the display layout source. In the case of maintenance, it goes through the same process, This kinds of web-based software development method were proposed by the various methods same as the tag library of JSP, But there are many problems to apply them and they are low productive comparing to the CIS based software development method, WFS(Neb Form System), which is suggested on this thesis, separates UI design from business logic on a web project and offers the better environment to develop web based software, Eventually WFS will improve the productivity to develop web based software.

  • This paper makes an attempt to look at the process of automatically generating an application software system based on the Entity-Relationship (E-R) model. Basically, the process consists of five steps as follows: First, the designer develops an E-R model of an real-world system. Second, the software generator automatically generates a stereo-type application system. Third, the generator produces database schema and link information between application programs. Fourth, the designer designs the user interface including menu, screen design and so on. Finally, the generator completes the process integrating all the elements of an application system. Five basic program generation rules, three extended rules and a database generation rule have been suggested. By following each rule with the generator, the designer can build an application with an extremely efficient manner compared with traditional approaches. A case study has been included in order to show the applicability of the automated software generation process suggested in this paper. It has been demonstrated from the case study that the idea of applying an automated generator in systems development based upon the E-R model worked well.

  • In this paper, a independent and structured microassembler was designed for easily changing the system design, and for designing various microarchitecture. When the designer's hardware and microprogramming process were made concurrently, it is needed to easily change or improve the instruction set and executable code format. But this type of developed environment requires a high const and a large software system. A proposed microassembler was designed so the designer directly defines the microinstruction set and format to be executed. And we implemented a module from each part of the software, so it is now possible to use practically and upgrade the function of each part, First, the symbol was separated from the assembler. And then microinstruction was copied into it. The microinstruction format was designed using the defined language that was designed for free microinstruction. This was implemented in an IBM-PC by using the C-language, FLEX,and BISON.

  • The purpose of the present paper are not to develope machine tools of new concepts and advanced mechanisms but to introduce and apply new methods and concepts in the design procedure by using and changing the previously existing technologies. In this paper 3D modeller was proposed for designing machine tools and the design and the better manufacturability checking than 2D one so that design error was dramatically reduced. As designer may easily understand the real shape of a part and assembly object, it's easy to draw the drawings not only in a conceptual design but also in a detailed design. Also, design automation software enabled designer to consider the real important design parameters by reducing time to spend in estimating and calculating the strength of the model by the computer aided automatic calculation instead of a tedious and complex calculation by manual method and help him to easily make the decision for selecting the stocks and design the structure of part or unit of machine tools.

  • Computer는 발명되서부터 매년 응용분야가 넓어지고 있다. 현재에는 情 報處理라는 말그대로 어떠한 형태이든가의 복잡하고 다량의 情報가 存在하는 곳 에는 computer를 導入할려고 하든가, 또는 導入이 끝난 곳에서는 보다 큰 大規模 의 system으로 擴張하려고 하는 생각들을 보통 가지고 있다. 이러한 요구에 응하 여 왔던 것이 hardware, oprating system, 그리고 application software이다. 그중 hardware나 operating system은 多小 變化하여 왔지만은, 方式的으로는 application의 특성에 의한 요구에는 별로 틀린것이 없이 대개 같은 종류의 것이 쓰여왔다고 할 수 있다. 따라서 무수히 變하는 application의 複雜한 論理를 實現 하는 것은, 그 책임이 application software 개발자에 걸려있다. 그러므로 이러한 것들은 개발자(designer, programmer) 들의 개인의 기술과 努力에 달렸다고 말할 수 있다.
