Tight fitting glove pattern is necessary to convey oscillation to the skin from the sensors attached on the hands as found in the haptic device. However, it has been difficult to provide customized glove pattern for haptic device so far. The objective of the paper is to develop a 2D pattern that fit tightly to hands by adopting the recent 3D technology to the clothing science. In this study, the user graphic interface application software(2C-AN) for the semi-automatic garment pattern generation has been utilized to develop the methodology of construct tight-fitting glove pattern for the hand in natural position. A basic pattern was developed directly from the 3D images of hand and the verification of the proposed pattern was also provided.

In this paper, we discuss the system configuration and the design issues of CATS-i, a set of installation and administration tools for Linux cluster systems. CATS-i enables users to manage cluster systems easily, quickly, and safety. It integrates many functions, ranging from installing operating systems and applications to real-time monitoring and management of various important resources. In addition, batch job submission and management are included. These functions support a single system image. Finally, a powerful graphic user interface based on Java lets users quickly understand the cluster status and conveniently use the CATS-i on the Web.

VNC 프로그램은 RFB(Remote Frame Buffer) 프로토콜을 사용하여 멀리 떨어진 시스템의 자원을 GUI(Graphic User Interface)를 통해 효과적으로 제어 할 수 있는 기능을 제공한다. 이를 이용하여 효과 적인 동기식 협업 작업을 지원하는 시스템을 구성할 수 있다. 본 논문에서는 Ultra VNC 프로그램과 RFB 프로토콜을 확장하여 같은 시간에 일어나는 인터넷 기반 협업 작업을 효과적으로 지원할 수 있는 CoVNC의 개발에 대해 기술한다. CoVNC를 사용하는 협업 작업장제공자나 협업 참여자가 협업 시스템의 구성과 실행에 대한 노력을 들이지 않으며 협업 작업에 몰두 할 수 있도록, 서버 설정을 저장하는 기능과 클라이언트가 한 번의 클릭으로 서버 접속을 할 수 있는 기능을 제공한다. 또한 작업장을 제어 할 수 있는 권한과 제어할 수 없는 권한, 그리고 클라이언트의 권한과 접속을 관리하는 관리자 권한을 제공하여 협업 작업에서의 혼선과 악의적인 작업 방해를 막을 수 있다. 이러한 기능을 지원하기 위하여 Ultra VNC 서버를 확장하여 CoVNC 서버를 개발하였으며, Java Viewer 클라이언트를 확장하여 CoVNC 클라이언트를 개발하였고, RFB 프로토콜을 확장하여 서버와 클라이언트가 새로운 기능에 대한 메시지를 주고받을 수 있도록 하였다.

In this paper, optimum design problem of R.C. continuous beam is considered and GUI system is developed for using at the practical design. Objective function lot formulation of optimum design problem is made up of the costs of concrete, reinforcing steel and formwork. Design variables are width, effective depth of the beam and steel ratio and design constraints are considered on the strength, serviceability, durability and geometrical conditions. The optimum design problem is solved by using sequential linear programming(SLP), sequential convex programming(SCP) and compared their effectiveness. Also this paper shows the application at practical design work according to the development of GUI system using visual basic.

An aerodynamic design tool was developed for small wind turbine blades based on the blade element momentum theory. The lift and drag coefficients of blades that are needed for aerodynamic blade design were obtained in real time from the Xfoil program developed at University of Illinois. While running, the developed tool automatically accesses the Xfoil program, runs it with proper aerodynamic and airfoil properties, and finally obtains lift and drag coefficients. The obtained aerodynamic coefficients are then used to find out optimal twist angles and chord lengths of the airfoils. The developed tool was used to design a wind turbine blade using low Reynolds number airfoils, SG6040 and SG6043 to have its maximum power coefficient at a specified tip speed ratio. The performance of the blade was verified by a commercial code well known for its prediction accuracies.

In this paper, we introduce a case study of developing a miniature humanoid robot which has 16 degrees of freedom, 42 cm heights, and 1.5kg weights. For easy implimentation, the integrated RC-servo motors are adopted as actuators and a digital camera is equipped on its head. So, it can transmit vision data to a remote host computer via wireless modem. The robot can perform staircase walking as well as straight walking and turning to any direction. The user-interface program running on the host computer contains a robot graphic simulator and a motion editor which are used to generate and verify the robot's walking motion. The experimental results show that the robot has various walking capability including straight walking, turning, and stairs walking.

The control system hardware consists of two micro-processors, analog and digital I/O circuits, various relay circuits, etc. Sensor fusion and moving cross algorithms are implemented to accurately estimate the roll angle and roll period. In addition, the control system adopts a fault detection algorithm to inform users of ART system faults. A touch screen in the control panel can display the ART system states and faults. The performance of the developed system was verified on real sea trials.

In this paper, we developed a green home simulator using LabVIEW for house designers or users to assess energy saving costs in an easy and direct way. The LabVIEW simulator has a strong graphic user interface, which is intuitive to general users. Therefore, the developed simulator enables one to gather information on electric power consumed in its house and to calculate efficiency for installing green energy generators such as solar and wind power generators. As an actual application, we simulate and compare the efficiencies of installing green energy generators at various cities and seasons using the developed LabVIEW simulator. The simulation results confirm that energy saving effects of green energies are easy to calculate by the proposed green home simulator.
