A photovoltaic panel is a device that, through the photovoltaic effect, converts luminous energy into electric energy. Photovoltaic generation system used infinity of solar energy, cost of fuel is needless and there in no air pollution or waste occurrence. This paper summarizes the results of these efforts by offering a photovoltaic system structure in 30[kW] large scale applications installed in Mokpo National University dormitory roof. The status of photovoltaic system components, are inter-connection and safety equipment monitoring system will be summarized as this article. This describes configuration of utility interactive photovoltaic system which generated power supply for dormitory. In this paper represent 30[kW] utility photovoltaic system examination result.

This study is to develop the interactive program for work-cell layout of SCAPA type robot using PC. To make the program interactively, we made use of the software which have the function of menu, dialog box, and graphic. By using the mouse, we can progress the program quickly and easily. It has 2 1/2 dimension and provides that one can layout the elements(robot, peripheral device, and etc.), create the work path, and calculate the robot cycle time. By comparing with cycle times of any number of work-cell layout for the same work, we can evaluate work-cell layout and select one work-cell layout to be considered optimal one which has the least cycle time.

With the fast increasing popularity of mobile services, ubiquitous mobile devices with enhanced sensing capabilities collect and share local information towards a common goal. The recent Mobile Crowd Sensing (MCS) paradigm enables a broad range of mobile applications and undoubtedly revolutionizes many sectors of our life. A critical challenge for the MCS paradigm is to induce mobile devices to be workers providing sensing services. In this study, we examine the problem of sensing task assignment to maximize the overall performance in MCS system while ensuring reciprocal advantages among mobile devices. Based on the overlapping coalition game model, we propose a novel workload determination scheme for each individual device. The proposed scheme can effectively decompose the complex optimization problem and obtains an effective solution using the interactive learning process. Finally, we have conducted extensive simulations, and the results demonstrate that the proposed scheme achieves a fair tradeoff solution between the MCS performance and the profit of individual devices.

Applying wireless mode to an existing wired home network system, the users became to use services of home network conveniently in their home. In order to construct a safe network in home network system, it needs user authentification and interactive authentification to mobile devices. In this paper, we propose an interactive authentification mechanism in order to make a safe home network system in mobile environment.

This paper presents a software design simulation method for controlling multiple mechanism carrier system (MMCS), which is mainly used in a wrapping machine or a case packing machine. This method uses a mechanical tool-work interactive model proposed in this paper, in order to represent the interactive behaviors between some tools and a work driven by their tools, in which low effect states of a work are defined. Based on this method, a 3-D simulation system has been built. It consists of shape modeling of each device, behavior definitions of tools, and control logic using if-then expression. By applying it to a ase packing machine having about 30 mechanical devices and 100 inputs/outputs for control, the effectiveness of this method has been shown in general verification of control logic specification in an early software design phase and the possibility of smooth communication tool between mechanical and software designers.

To make this program interactively, we made use of the software which has the function of menu, dialog box, and graphic. By using the mouse, we can progress this program quickly and easily. It has 2Y2 dimension and provides that one can layout elements (robot, peripheral device, and etc.), create work path, and calculate cycle time of working robot. By comparing with cycle times of any number of work-cell layout for same work, we can evaluate work-cell layout. Finally, we can select one work-cell layout to be considered optimal one which has the least cycle time.

최근 들어 핸드폰이나 PDA 등 휴대용 단말기의 보급이 급격히 늘면서 이를 통한 미디어 감상의 수요는 많이 증가하였다. 또한, 멀티미디어 기술의 발전 방향도 기존의 단방향 서비스를 벗어나 사용자의 기호에 따라 스토리를 전개해나가는 인터렉티브 미디어에 이르렀다. 따라서, 본 연구에서는 본 연구팀이 기존에 진행했던 연구에 이어서 이러한 인터렉티브 미디어를 지원하기 위한 전체 시스템을 설계하였고 이를 PDA 상에 구현하였다. 이 때 비디오 코덱으로는 JVT(H.264)를 사용하였으며 컨텐츠 제작을 위한 마크업 언어는 자체 정의한 IML(Interactive Media Language)를 사용하였다. 또한, 본 논문에서는 이러한 구현 과정에서 이동 단말기 들이 공통적으로 가지는 취약점인 CPU, 메모리 등의 한계를 극복하기 위한 방안도 살펴보았다.

This study proposed 'Body Food,' an interactive tactile mat that provides interactive visual responses and induces physical activity in young children at the time of developing tactile and five senses, along with the touch of various stimuli. The product combines fiber materials and digital content to achieve a variety of visual and auditory responses in real time when children touch the fabric. User tests were conducted for 4-year-olds and the result was positive in terms of physical exercise and artistic experience, but quantitative testing is required to generalize it. In the future, we will complement physical and digital contents to realize more complete product.
