This paper introduces a new concept of automation for bio-production with tele-operative system. The proposed system showed practical and feasible way of automation for the volatile bio-production process. Based on the proposition, recognition of the job environment with object identification was performed using computer vision system. A man-machine interactive hybrid decision-making, which utilized a concept of tele-operation was proposed to overcome limitations of the capability of computer in image processing and feature extraction from the complex environment image. Identifying watermelons from the outdoor scene of the cultivation field was selected to realize the proposed concept. Identifying watermelon from the camera image of the outdoor cultivation field is very difficult because of the ambiguity among stems, leaves, shades, and especially fruits covered partly by leaves or stems. The analog signal of the outdoor image was captured and transmitted wireless to the host computer by R.F module. The localized window was formed from the outdoor image by pointing to the touch screen. And then a sequence of algorithms to identify the location and size of the watermelon was performed with the local window image. The effect of the light reflectance of fruits, stems, ground, and leaves were also investigated.

Art is an ongoing process of experimenting and challenging. The challenge and experiments of the artists encompass both the conceptual process and the expressive process of creating artworks. It is not mandatory to use cutting-edge technologies for interactive performances, since they can be realized by adapting pre-existing technologies. Using previous technologies reduces the difficulties in the production process and makes it easier for the audience to understand the way of participation. In this paper, propose an ARS-server-based control system in which a large audience can participate during a performance to control certain features on stage. This system was first proposed during the 'Ubiplay Workshop and Seminar' hosted by the GSCT, KAIST, and applied to the digital performance 'Syntasia' in June and July, 2007, hosted by the Goyang Culture Foundation.

의사결정지원시스템의 성패여부는 사용자가 사용하기에 편리하고 효과적인 모형으로 구축되었는가에 달려있다. 아무리 훌륭한 시스템 분석기법을 활용하였다 하더라도 사용자가 불편하여 사용하지 않으면 그 의사결정 지원 시스템은 사장되고 말 것이며 많은 시간과 정성을 들여 개발한 연구결과가 빛을 보지 못할 것이다. 본 연구에서는 일반적인 중소기업의 제조업 환경에서 생산 일정 계획 수립을 위한 의사결정 지원 시스템의 구축을 중심으로, 사용자 편의를 고려한 시스템이 갖추어야할 사양 및 이에 대한 설계, 객체지향 프로그래밍 기법의 활용, 시스템 구현상의 문제점 등에 대하여 구체적으로 설명하고 해결방안에 대하여 고찰한다.

A hologram projects a 3 dimensional video as same as a real subject and it is made by principles of holography. Many researches about holographic technology have been developed. Studies for visualization of 3D videos, holographic storages, and optical media have proceeded mostly in engineering. It is hard to find any researches about the convergent system from the viewpoint of interactive elements and motion graphic design such as this paper's concept. Most studies of augmented reality have been developed in the domain of technology and education but the field of content production. AR has been convergent with various fields and media, so it is time to make an active progress in the study of convergent content development. The goal of this study is to develop cultural contents and create new values through the convergence of holography and AR. The purpose of this paper is to propose the way of developing the convergent type of cultural contents and construct the production system by the new approach to users using the convergence technology of holography and augmented reality.

A grid-connected photovoltaic (PV) system comprised of multicrystalline silicon (mc-Si) modules was installed in a cold climate region in the U.S. This roof-mounted stationary PV system is a real-world application of PV for building energy generation in International Energy Conservation Code (IECC) Climate Zone 5 (and possibly similar climate zones such as 6, 7 and 8), and it served the purposes of research, demonstration, and education. The importance of this work is highlighted by the fact that there has been less emphasis on solar PV system in this region of the U.S. because of climate and latitude challenges. The system is equipped with an extensive data acquisition system capable of collecting performance and meteorological data while visually displaying real-time and historical data through an interactive online interface. Experimental data was collected and analyzed for the system over a one-year period with the focus of the study being on measurements of power production, energy generation, and efficiency. The annual average daily solar insolation incident upon the array was found to be $4.37kWh/m^2$. During the first year of operation, the PV system provided 5,801 kWh (1,264 kWh/kWp) of usable AC electrical energy, and it was found to operate at an annual average conversion efficiency and PR of 10.6 percent and 0.79, respectively. The annual average DC to AC conversion efficiency of the inverter was found to be 94 percent.

J.E.N(Joint Enjoyment Network) is the ubiquitous UCC play contents system that provides amusements off-line by utilizing the UCC that people are able to participate in. It is also the entertainment service system that is devised to use contents that could be enjoyed through the cell phone and to make people participate in production, in cases of meeting people off-line during their pastime. The development of this system begins from pointing out the problem of the limitation of the UCC that does participate in production but the produced contents could only be watched, and the UCC only works on-line. The goal of researching this ubiquitous UCC play contents is to suggest the UCC entertainment service system that are available off-line by applying the interactive system to UCC and, by this, to obtain the positive responses about the off-line participating UCC contents. In this research, it chooses scenario and 테스크 performance as the method of deriving the participating UCC from the off-line, and it suggests the ubiquitous UCC play contents system through analyzing the behaviors in each off-line place. Moreover, by developing the prototype that could practically perform the system, it verifies the potentialities of the UCC entertainment service. The anticipation of this study is to make people participate and enjoy not only in production, but also in the contents made. This research will provide the modern people who concern about where to go and what to do with the amusements and will also present a way of new form of contents mixed with UCC and the entertainment service.

A virtual studio is a new video production environment using interactive computer graphics and imaging media technology. The traditional chroma-keying with two-dimensional background is replaced by an advanced keying method with a dynamic computer-generated, three-dimensional background. We have developed a virtual studio system that is practical to use in the real production environment. It has not only essential features that are common among various commercial virtual studio systems, but also unique feature that help the producer to construct virtual studio sets and scenarios efficiently such as span graph, robust backup controller, and 3 dimensional character generator supporting all languages. Our virtual studio system was used in live broadcasting and proved that the system was practical enough. In this paper, we will introduce the structure and the major features of our system, called VdreamSet, and application examples to broadcasting.
