  • As of July, 2009, Chungnam Province get DI (Direct Investment) of 2,502 corporations as the amount of 31 billion US dollars only for 3 years. Especially, Chungnam provincial governor make a excessive performance of 2.5 times comparing to the target number, 1,000 of inviting capital, that is public promise in the election. Now, the amount of inviting foreign capital is 1.2 billion dollars, at the end of this year it might be 1.4 billion dollars just in case of making a success on going negotiations. This outstanding performance comes from governor's leadership and aggressive strategies of well-trained subordinates. Chungnam Province has nation-wide multiple targets focused on interdisciplinary industries including strategic industries of display, auto-parts, steel, and oil-chemistry. Also, it has organic network system based on the very descriptive and accurate informations managing the task force team consisted of 35 competent members. In conclusion, the core competence of inviting foreign capital in a regional government is governor's strong leadership, activated organization consisted of specially well trained subordinates, and predominant differentiated strategies in details.

  • This study is concerned with the identification of the concepts and characteristics of the traditional access of small scale fishery and traditional small scale fishery based on the classification of fisheries under Fisheries Law, As we called, these fisheries are the small scale of artisanal fisheries. These traditional small scale of artisanal fisheries have been developed throughout the most coastal fisheries but have never been included the institutional fishery system and policy since industrial fisheries have been exploited. By this reason there was no studies to understand and identify these fisheries as fisheries under category of institutional fishery system. Recently by the Fisheries Law, my Person who desires to operate these fisheries, shall report to the provincial governor and then these fisheries were incorporated into the category of fisheries to be reported. But this case of the administrative practices should be not consistent with the classification of fisheries under Fisheries Law. The traditional access of small scale fishery is a derivative concept of fishery categories under the institutional fakery system Because this fishery under institutional fishery system can not be establish the right of fishing by fishery right system technically but the right of fishing is supported by the fishing access system only. Therefore, It is a mistake for the provincial fishery governor to adopt such a policy that the fishing right of the traditional access of small scale fishery which is different from the fishing based right is restricted by the factors of fisheries to be reported. On the other hand the traditional small scale fishery is coincident with the traditional access of small scale fishery and the common fishery under the style of utilization of fishing gear and fishing gear and methods. But this fishery has never been included the fishery categories supported by the government subsidy policies and considerations and has been remained with indifference during the last few decades. Anyhow the fishing right of these fisheries have been assured under the institutional fishery system, any person who desires to operate this fishery should have a fishing right against the public or private uses of fishing ground such as land reclamations and other coastal zone development. A deprivation of the fishing right of this fishery by the conflicts of these public and private uses of fishing ground is not regarded as appropriate according to the social welfare policy. Also it is the administrative expediency to support the fishing right of this fishery under the fisheries lobe reported.

  • In this literature, we are introduce a basic design of multi energy hub based on natural gas governor station. Multi energy hub consists of turbo expender generator, phosphoric acid fuel cell, pressure swing adsorption, H2 charging station, utilities and etc. We design a hybrid energy hub system that provides energy using these complex energies, and calculates the amount of electricity that can be produced and the amount of hydrogen charged through the process analysis. TEG and phosphoric acid fuel cell produce 2,290 to 2,380 kW and can supply electricity to 500 houses. In addition, By-product H2 gas is refined to H2 vehicle fuel. This will help maximize the balance of energy demand and supply and improve national energy efficiency by integrating unused decompression energy power generation technology and various power generation/heat source technologies.

  • This paper presents a method for the derivation of model parameters of a co-generation system using data measured through on-site generator characteristic testing and validates its model parameters. Dynamic models such as generator, excitation system, and turbine/governor are mainly dealt in this paper. For the purpose of validation of derived model parameters, the measured results are compared with simulation results. The comparisons between measured results and simulation results show good match.

  • In the conventional load flow technique, it is assumed that the generator at the slack bus is used to supply the transmission losses and the change of power due to the generator outage. The assumption is not true in physical sense. This paper presents a new load flow technique that considers the governor-frequency characteristics and load-frequency characteristics and the technique is consistent with the actual power system phenomenon. This paper proposes an efficient methodology using sensitivity with the new technique for contingency analysis, which is used to calculate the line flows. Computational results of this technique applied to IEEE 14-bus system are presented.

  • Design sensitivity is an important is an important device in improving a mechanical system design. A continuum design consists of the shape and orientation design. This research develops the shape and orientation design sensitivity method. The configura-tion design variables of multibody systems define the shape and orientation changes. The equations of motion are directly differentiated to obtain the governing equations for the design sensitivity. The governing equation of the design sensitivity is formulated as an over determined differential algebraic equation and treated as ordinary differential equations on mani-folds. The material derivative of a domain functional is performed to obtain the sensitivity due to shape and orientation changes. The configuration design sensitivities of a fly-ball governor system and a spatial four bar mechanism are obtained using the proposed method and are validated against those obtained from the finite difference method.

  • The paper presents a method of constructing simple fuzzy control rules for the determination of stabilizing signals of automatic voltage regulator and governor, which are controllers of electric power systems. Fuzzy control rules are simplified by considering a coordinate transformation with the rotation angle .theta. on the phase plane, and by expanding the range of membership functions. Also, two rotation angles .theta. $_{1}$ and .theta. $_{2}$ are selected for the linearizable region and the nonlinear one of the system, respectively. Here, .theta. $_{1}$ is chosen by the pole assignment method, and .theta. $_{2}$ by a performance index. Fuzzy inference is applied to the connection of two rotation angles .theta. $_{1}$ and .theta. $_{1}$ by regarding the distance from the desired equilibrium point as a variable of condition parts. The control effect is demonstrated by an application of the proposed method to one-machine infinite-bus power system.

  • A new robust load-frequency control (LFC) methodology is proposed for nonlinear power systems with the valve position limits of the governor in the presence of parametric uncertainties. The Takagi-Sugeno (TS) fuzzy model is adopted for fuzzy modeling of the nonlinear power system. A sufficient condition of the robust stability is presented in the sense of Lyapunov for the TS fuzzy model with parametric uncertainties. The intelligent digital redesign technique for the uncertain nonlinear power system is also studied. The effectiveness of the proposed robust fuzzy LFC controller design method is demonstrated through a numerical simulation.

  • THERP (Technique for Human Error Rate Prediction) methodology has been widely used for probabilistic safety assessments. The NUREG report involving this methodology is also called the HRA handbook. The THERP assumes that all actions involved in implementing a task are considered as components. In this paper human error rates associated with maintenance are evaluated by the THERP methodology. A gas governor system is used as an example which is also a risky system like nuclear power plants. It is also demonstrated that this approach is flexible in that it can be applied to any operator actions related to test and maintenance.

  • The system components and implementation methods to be considered when constructing a system for plant safety training in a virtual environment were classified according to plant characteristics. When constructing a safety training system based on VR, the necessary components may be different according to the characteristics of the plant, and the basic system components to be built according to the target plant are presented. In order to support the proposed system, we implemented a city gas governor safety training system, which is a relatively simple facility. Through this, we propose guidelines for the construction of a suitable VR-based plant safety training system in the plant to be applied.
