This study investigates the merits of incorporating augmented reality in mobile games and proposes a mobile game application that combines augmented reality technology with gaming. The proposed study postulates that augmented reality technology can be employed for developing games on smartphones. The proposed application involves the implementation of a 3D virtual object in the real world by incorporating a target image. The proposed application also employs an intuitive interface with simplified manipulation based on touch, and allows players to collect and combine items for acquiring new items, thus making it elementary to pass the game stages. Furthermore, a ranking system has been introduced in the proposed application for enhancing the amusement factor of the game. The novelty of the proposed application lies in the fact that the virtual button function has been employed for combining physical and virtual objects while playing the game, without incorporating location-based services.

We describe about the graphic simulation system which supports the determination of efficient multi-robot motions during cooperation. For the construction of the simulation software for multi-robot motions, two problems are presented. First problem is that all the robot motions must be determinded using both the desired object motions and the holonomic constraints with the object. To find the robot motions combined with the various object motion path, the robot motions are derived from the desired object path instead of a master robot path. Therefore robot motions can be easily modifiable with the various object motions. This type of motion determination is different from that of the master-slaves method using the master robot motions. The other is that the developments of robot application softwares need a heavy cost when the participated robots or the tasks given to the robots are changed. Based on object-oriented programming paradigm, we present useful software objects describing robot application programming environment. The object-oriented programming paradigm increases the software reusability, reliability, and extensibility, and also provides the structual concepts to cope with the various demands of robot application programming.

As a software development methodology, object-oriented paradigm that has execellent reusability, portability, and extensibility, is currently being used in many application fields. Especially, UML(Unified Modeling Language), which is recently released as a third generation methodology for the object-oriented system development, has many advantages such as generalization, certainty, visualization. For this reason, the usability of UML in manufacturing system control is expected to increase. In this paper, analysis and design of FMC control system are peformed by UML. Software objects to accommodate the dynamic environment of FMC operations are modeled by using the diagrams of UML. The objective of this paper is to suggest a generic framework to design FMC control software.

This paper describes the design and implementation of a PC(personal computer) based open architecture machine tool controller. The hardware of open architecture CNC has generally a motion control board on a PC for controlling a servo motor. But this paper describes open architecture hardware that consists of a PC, a counter board a DAC board and a DIO board only. This makes it easy to generate CNC software module in a hardware-independent way. The proposed open architecture CNC software runs on the MS-Windows NT. The paper describes a method of con-trolling servo motors using a real-time timer of MS-Windows NT and a commercial real-time operating system on the MS-Windows. NT. An open and reconfigurable software module is made up of an object and an API(application programming interface). Using the object and the API a new CNC system can be quickly configured to control dif-ferent machine tools. The proposed open architecture CNC system is applied to 4-axis lettering center.

Over the past several decades, several architectural approaches have been applied to develop Information Systems, The software architectural model has been recognized as one of the most important methods for improving productivity. Most conceptual models are difficult to understand and interpret at various system models. As a consequence, conceptual models of many Information Systems fail to represent, exploit, and apply to various aspects, which is needed for reducing development step of the architecture. In this paper, we will explain the architectural model as the 4＋1 View of UML. This model integrates the Knowledge Management System into five views： the Logical View, the Process View, the Deployment View, Implementation View, and the Use-Case View. Moreover, this paper will not only provide information on the application of the software architectural model by stakeholders, but also ultimately improve productivity.

In this paper, faults existing in a software system is classified into three types; simple, degenerative and regenerative faults. The reliability functions and failure rates of both a software module and system which have a mixture of such faults are obtained and the expected number of failures in the system after time T is also derived. Using the formulas obtained, a cost-reliability model and an efficient algorithm for optimal software release time are proposed via nonlinear programming formulation ; minimizing the total test cost with constraints on the failure rates of each module. Application of this model to several cases are presented and it appears to be more realistic.

In these days companies are rapidly implementing the extended enterprise collaboration to provide enhanced management services and products based on the enterprise integration that human resources, technologies and the management process. In this corporate environment, ASP (Application Service Provider) which is the developed type of outsourcing in the area of information technology, is a good alternative for corporate information system management. ASP defines as a software leasing service which is supplied through networks instead of purchasing application software with high price. For successful implementation of ASP, it is necessary to develop the certification methodology to ensure safety and reliability of ASP. The paper provides the safe and reliable certification methodology for ASP. In order to develop it, the critical issues related to service quality and certification of ASP are identified and the systematic certification methodology of application and service provider(service environment) domains of ASP are provided. A evaluation method for the developed certification methodology is also proposed.

The objective of this paper is to present the development and application of interface software between robot and F/T sensor for force control. The interface software for among the robot controller, F/T sensor, and host PC is based on interrupt-driven method. To show the suitability of developed interface software, writing-task is performed in real time using F/T sensor that mounts on the wrist of the robot and Scara type 4-axis robot.

Microprocessor의 출현은 전자계산기 구조에 일대혁명을 일으볐으며 최근 몇년간 microcomputer가 세게적인 화제의 초점을 이루고 있고 그 응용은 극히 강력한 기대와 관심을 불러 일으키고 있다. Microcomputer의 가장 큰 특징은 micrs computer 자체가 한 system의 component로 사용될 수 있다는 점이며 application software의 개발여하에 따라 무한한 가능성을 약속해 주고 있다. 본 논문에서는 M6800 application software를 개발하기 위하여 M6800 crossassembler를 작성하였다. M6800은 Motorola에서 개발한 micrs computer로 전세계적으로 가장 널리 사용되고 있는 것 중의 하나이다. 본 논문의 2장의 첫 부분에서는 M6800 assembly language가 소개되고 두번째 부분에서는 cross-assembler의 기본적인 특성이 기술되고 있다.
