  • We have recently studied the application of Information Technology to agricultural industry for competitive power. Because the big stockyards are far away from the house, we need a realtime monitering and control system to manage it efficiently. This paper presented design and implementation for a realtime monitering and controlling system that we can use to watch an movement of an electronic devices in the stockyards. Compared to other systems, we have more trust in our system by confirming an operation of devices through a realtime video streaming.

  • The purpose of this study is to assess the recovery rate of vegetation structure after restoration works at the damaged Nogodan area in Jirisan National Park. Fourteen monitoring plots were set up at restoring work area and twelve control plots were set up at natural forest near monitoring plots. Flora, Relative Importance Percentage and Similarity Index were analyzed. Mean Similarity Index between monitering plot and control plot near helliport area showed thirty five point two percent and height of shrub layer recovered up to twenty percent, approxomately durindg twenty three years after experimental restoration works. Mean Similarity Index between monitering plot and control plot around Nogodan peak area showed seventeen point six percent but height of shrub layer recovered up to twenty percent, approxomately during ninteen years after restoration works. Mean similarity index between monitering plot and control plot on transfered millitary area showed thirty four point three percent but coverage of shrub layer showed twenty percent,approxomately during seven years after restoration works. Long term monitering shall be necessary for developing assessment criteria of ecologial restoration and ecological restoration technology.

  • Multicharacteristic quality control is concerned with monitering production processes and inspecting the quality of a lot when the state of a process or the quality of an item is determined by a number of quality characteristics. This paper reviews procedures currently available for multicharacteristic quality control when the quality characteristics are either variables or attributes.

  • A few years ago, The trains had little control equipment so the trains had little data transmission between control equipment. Recently, there is a lot of control equipment in a train as traction control, air conditioners and even internet access. for this reason, vehicle network must allow for the big amount of transmission data and must ensure the high reliability. In this paper we present monitering system for verify high reliability of data transmission of MVB of TCN which is an international standard of IEC 61375.

  • DC-Motor is needed more and more sophisticated control to follow the highest precision of industrial automation and used in a number of control equipment or industrial fields. It is also useful to control single crystal(Al2O3) growth. It is possible to procure a quality crystal utilizing a DC-Motor, if you mix Hydrogen and Oxygen gas properly and keep proper temperature in accordance with time process. In this paper, we will study about electrical valve positioning system for the gas mixture to improve the quality of single crystal($Al_{2}O_{3}$) growth and we will design about realtime monitoring systems of the automatic gas contol DC- Motor for single crystal($Al_{2}O_{3}$) growth

  • Purpose: We investigate to evaluate the effects of scapular stabilization exercise on dynamic standing balance in stroke patients. Methods: Thirty hemiplegic patients participated was divided into control group and training group randomly. Control group(n=15) had only general rehabilitation training and training group (n=15) had both the general rehabilitation training and intensive scapular stabilization exercise. They were treated for 15minute/5 times/4 week. We measured PALM (palpation meter) to measure affected side's distances from spine to scapular. We measured FRT (functional reach test), FSST (four squared step test), and BPM (balance performance monitering) to evaluate dynamic standing balance. Results: Training group showed a significant difference in the distances from spine to scapular, FRT, FSST, and variables of BPM comparing control group (p<0.05). But control group was not significant difference. Conclusion: These results suggest that scapular stabilization exercises have positive effects on dynamic standing position.

  • The first aim of the study is to improve the productivity by uniformizing the thickness of coating and reducing quality-inspection time. The second aim is to cut down on the raw materials for coating by prevent the waste of spraying in the air during a painting process through a real-time coating-size-recognition monitering to fit the target components. To achieve the two aims, a simplified version of automatic coating control system for recognition of coating for vessels and Spray. With the sytem, following effects are expected: First, quality improvement will be achieved by uniformizing the film-thickness. Second, it will reduce the waste of coating paint by constructing the speed of the coating, the spray gun robot transfer time, and the number of DBs according to the size of the vessel. Third, as a 3D industry, it will be able to solve the difficulty of supply of labors and save up the labor costs. Therefore, in the future, further research will be needed to be applied to various products with DB design that designates the variable value, which is added for each type of pieces by comparing the difference between various types of workpieces and linear ones.
