Budget for the industry-university co-operation is expanded by the increasing of the importance of industry-university co-operation. Even though, industry and university do not co-operate voluntarily. Until now, there is no research about industry-university co-operation focusing on SMEs. This paper is about industry-university co-operation focusing on SMEs. In this paper, we introduce the status and structural problems of industry-university co-operation related with SMEs. And we derive the problems of industry-university co-operation in terms of co-operation purpose. Industry-university co-operation in terms of co-operation purpose can be categorized as R&D, technology transfer, infrastructure, and manpower training. And last, we suggest how we improve the industry-university co-operation system to benefit SMEs.

The number of the PV systems installed in south korea has been gradually increasing. Interest of operation & management of PV System is rising up as PV System installation trends to increase. The vital function of operation & management is the monitoring system. Most monitoring systems are only available for equipment of suppliers and manufacturers. In this study, a monitoring system was implemented to support multi-domain equipment (inverter, junction box, water distribution board, environmental sensors) that are not limited to specific manufacturers. Monitoring system includes a visualization function, which makes it easy for users to check the power generation and the operation status of the equipment of PV System. In the future, this monitoring system will be utilized as an operation & maintenance foundation element in the PV system industry.

A three-arm PWM UPS is realizable low price and small size UPS. In this UPS configuration, the center arm operates in both PWM converter mode and PWM inverter mode. Therefore, the operation of this UPS differs from the conventional UPS. In this paper, the three-arm PWM UPS is analyzed and a trial product is realized.

본 논문에서는 한국기술교육대학교에서 새롭게 도입예정인 장기현장실습 제도(IPP:Industry Professional Practice)를 성공적으로 운영하기 위해 아시아(일본, 홍콩 및 태국) 대학의 코업 프로그램 사례들을 분석한다. IPP(Industry Professional Practice) 제도는 학부교육과 기업체 근무를 통합시킨 한기대의 새로운 산학협력 교육모델로 대학 졸업생의 취업역량을 강화하고, 기업에서 필요로 하는 산업인력을 양성하고자 하는 제도이다. 한기대의 장기현장실습(IPP) 프로그램을 성공적으로 운영하기 위해 아시아 대학 중 일본의 교토산업대학, 홍콩의 홍콩 폴리텍 대학 그리고 태국의 Suranaree 대학에서 실시하고 있는 코업프로그램들의 특징, 역사 및 운영현황 등을 살펴보고, 장단점등에 대해 비교분석하였다. 이러한 다양한 아시안 대학의 코업프로그램들의 사례분석을 기초로, 한기대의 장기현장실습(IPP) 프로그램이 나아가야할 방향을 제시한다.

In this work the Model Algorithmic Control (MAC) method is applied to control the grade change operations in paper mills. The neural network model for the grade change operations is identified first and the impulse model is extracted from the neural network model. Results of simulations for MAC control of grade change operations are compared with plant operation data. The major contribution of the present work is the application of MAC in the industrial plants based on the identification of neural network models. We can confirm that the proposed MAC method exhibits faster responses and less oscillatory behavior compared to the plant operation data in the grade change operations.

The purpose of the present study is to identify the drying cylinder model in paper plants and to analyze characteristics of process responses for changes in input variables. The model developed in this work is based on actual plant operation data and the steam pressure applied to the cylinder behaves as one the main variables. It is found that heat transfer coefficients from the condensate to the canvas could be represented as empirical relations based on heat conductivities and operation date. The effectiveness of the cylinder model is demonstrated by the measured moisture contents and web temperature. Using transfer functions derived from the cylinder model stability of the drying process is analyzed.

Embossing treated fruit bagging paper was prepared with newly designed embossing roll and mechanical properties of fruit bagging paper were evaluated. The embossing technology was developed. First of all, embossing roll was designed in Ginyong Embo(Co) for the embossing process of fruiting bag. The embossing treated fruit bagging paper was manufactured in Agro(Co) at plant scale. The mechanical properties of embossing paper was investigated and operation efficiency of bagging was tested at field. The properties of embossed paper was quit satisfied for fruiting bag for cultivation of apple and pears.

In most shipyards Floating Dock-gate System is adapted for dry docks. For the safe launching of ships in dry docks, smooth operation of dock-gate must be guaranteed. So it is very important to grasp its behavior in waves for securing the high productivity and the safety of workers. Its seakeeping ability was estimated numerically at the floating conditions and the free roll decay and the seakeeping model tests of dock-gate was carried out with bilge-keels of 3 different widths which have a scale of 1 to 20. More than 20% decrease of roll motion was observed in irregular beam seas by applying a bilge-keel system to the dock-gate that is long and narrow.

In this work we developed the closed-loop model of a paper machine during grade change with the intention to provide a reliable dynamic model to be used in the model-based grade change control scheme. During the grade change, chemical and physical characteristics of paper process change with time. It is very difficult to represent these characteristics on-line by using physical process models. In this work, the wet circulation part and the drying section were considered as a single process and closed-loop identification technique was used to develop the grade change model. Comparison of the results of numerical simulations with mill operation data demonstrates the effectiveness of the model identified.
