In this paper, the geometric design for the body of a 3"-PFA-lined plug valve is concerned, and body model which has less deformed PFA-resin after infection molding process is proposed. A CAE software is used to simulate the deformation due to heat in cooling. To reduce the deformation, some small shapes are added to PFA-resin surfaces related on wall of the valve housing. And thermal stress simulation with FEM methodology is followed after that. Also, the 3D-CAD package is used during the design processes. In this study, I tried to present the possibility to use the FEM analysis in the solid modeling process. So, the design engineer will be able to use analysis package effectively on his job within the limited range.

In this paper, kinematic analysis for a planar 3-DOF redundant stage which has four actuators is presented by using SimMechanics software package. SimMechanics is a block sets of the Matlab/Simulink package. The SimMechanics enables a simplified model for a complex kinematic mechanism, since kinematic relationship between joints and linkages for the kinematic chains are expressed as line vectors and block diagrams. Here, positional error and limit values of movement ranges of the stage are evaluated by using the SimMechanics. The validity of the kinematic characteristics model was compared with theoretical kinematic analyses for the 3-DOF stage.

A curriculum for teaching materials in Science Education was studied as a model for modified experiment on fundamental courses. Conscious effort can be made to desingn experiments that require minimum apparatus: that require low-cost equipment that can be made from cheap locally available materials. Computer-aided instruction programs at high school, freshman course level have been developed. The software package was consist of five programs: The program contains explanation and problems for the calculation of resonance energy, molecular structure, mole concept. Rutherford's experiment. thermodynamic processes. Special course equipment package explanation mole concept, Rutherford's experiment, thermodynamic processes. Special course were designed in Science Education with the understanding that to a certain extent science values would be covered in all of the modified experiments and program models.

This paper introduce of program package for the numerical analysis of Electromagnetic field analysis using Finite Element Method, called Electro Magnetic Field(EMF). This software tool is developed by Changwon Nat'l Univ. cooperative with Hanyang Univ. and produced on a commercial scale. EMF has a simple, easy to use graphical interface which steps user through th problem setup, high accurate solution, and fast computation.

It is very important to understand the 3-dimensional movement of a robot manipulator in developing a robot manipulator system. The robot design software package is required to test the specification. Usually these robot simulators are turn-key based and not possible to be used on the other robot system. The aim of this paper is to develop a general purpose robot simulator. AutoCad is selected for the developing environment to avoid the difficulties of building a cad system from the scratch. Because Autocad provides a semi-open structure to a Lisp programmer, it is quite successful to achieve the goal of building the simulator. At the moment the kinematic analysis is possible on the package. Further study will be advanced to the application and analysis of dynamic area, which would not be that difficult to be implemented, considering the many third party tools available for Autocad.

Typical misconceptions on Enterprise Resource Planning (ERP) among practitioners and researchers are reviewed. Companies can make, buy, or rent ERP solutions, but typically, ERP is conceived as ready-made, off the shelf application software package. The benefits of ERP adoption are frequently generalized without proper clarification of the requisite conditions. The specific outcomes of ERP adoption are not adequately differentiated from those of general computerization. To avoid the side-effects caused by those misconceptions, we 1) clarify the concept of ERP and the methods of sourcing it, 2) specify the requisite conditions for the benefits from packaged ERP solutions, and 3) explain the generic characteristics of ERP, direct effects and resultant possible outcomes of the adoption of ERP.

A novel ecosystem surrounding developing, publishing and using of smartphone applications is driving a new paradigm in software industry. Thousands of applications are newly published on appstores everyday. However more than 97% of them happen to be downloaded less than 1,000 times and resultingly disappeared out of user's interesting. It means that so many efforts and time of developers are vanished. In this paper, we proposed a new architecture to increase code reusability of Android applications so that the time and efforts to develop new applications can be shortened. The proposed architecture, an extended Intent mechanism, supports sharing of Android components among the applications registered in different servers as well as in the same Android device. We designed a new Intent mechanism by extending the PackageManager service and by adopting a new class for ServerPackageManager service.

The Monte Carlo (MC) method has become an indispensable part of the nuclear radiation research field. Several widely used and well-known MC packages were developed for simulation of radiation transport and interaction with matter. All these MC packages require users to prepare an input script. The input script can become lengthy for complex models. The process of preparing these input scripts is time-consuming and error-prone. In the present work, we have developed an open-source GUI computer program for modelling radiation transport and interaction in multi-segmented slab phantoms using grid-based system for the widely used PHITS MC package. The developed tools would be useful for future users of PHITS MC package and particularly inexperienced users. The present program is distributed under GPL license and all users can freely download, modify and redistribute the program without any restrictions.

본 연구는 콕스회귀분석과 누적한계추정법으로 1995년부터 2015년까지 1,084개의 국내 소프트웨어 기업을 분석하고, 생존율과 생존의 결정요인을 밝히는 것이다. 분석 결과 생존율의 경우, IT서비스, 패키지 소프트웨어, 게임 소프트웨어, 인터넷 서비스 각 분야별로 다른 형태를 보였다. 또한 연구개발 투자와 기업의 매출액 및 자산증가율로 나타나는 성장성은 생존에 긍정적이었으며, 여유자원은 부정적인 영향을 미쳤으며, 나이와 규모는 그 영향을 찾을 수 없었다. 이러한 결과는 소프트웨어 기업의 생존 전략과 정부의 지원 정책에 있어서 산업과 기술의 특성을 고려해야 한다는 점을 시사한다. 본 연구는 90년대 말 외환위기라는 특수 상황이나 제조업 중심으로 진행된 국내 생존분석의 영역을 최근 중요성이 커지는 소프트웨어 산업으로 확장했다는 의미가 있다.

The software which is used for electronic bulletin boards have shortcomings that the addition of new function and new information's type to the order point software is very difficult, and the aggressive adaption of newly introduced type of media is impossible because the software is developed by custom solution. Eventually new cost and time are required to enhance functionality or performance to software of DID(Digital Information Display). In this paper, we proposed the scheme to package DID's contents and to customize it using plug-in method. We conducted a case study of this scheme. The platform which can install Apps to DID as one of content was designed. Apps can be inserted by plug-in type on DID platform and run separately with DID framework. As a result, We got advantage that various contents, functions and Apps which are drived on Android can be displayed without any restriction and dependency because Apps itself is one of dynamic notice object. This solution increase reusability of Apps or contents, and can be used easily in various places such as airports, stations, terminals, and front desk by customizing.
