There is a growing awareness about the role of the board of directors in decision making, which is crucial to vitalize board activities in Korean firms. Given the academic and social needs, the current study is designed to identify the relationship between board independence and the board involvement of directors, highlighting the important aspects of information provision from diverse channels and information sharing among external directors. In this study, I include not only traditional variables to address the structural independence of the board but also the information provision and information sharing variables to explain how external directors, on average, are involved in board decisions. The research results from 136 Korean business samples show positive relationships between board independence and board involvement, but the influence of information provision and sharing proves to be significant in increasing the level of the board involvement of external directors. These findings suggest that active communication and information sharing among external directors, as well as an independent structural design for the board of directors, are important factors to improve the level of board involvement. Based on these results, the current paper provides theoretical and practical implications for corporate governance and knowledge management. Future research directions and limitations are also discussed.

According as the drivers increase who have their cars, the comprehensive studies on the automobile for the traffic safety have been raised as the important problems. Visual Recognition System for radio-controled driving is a part of the sensor processor of Unmanned Autonomous Vehicle System. When a driver drives his car on an unknown highway or general road, it produces a model from the successively inputted road traffic information. The suggested Recognition System of the Road Traffic Safety Information Board is to recognize and distinguish automatically a Road Traffic Safety Information Board as one of road traffic information. The whole processes of Recognition System of the Road Traffic Safety Information Board suggested in this study are as follows. We took the photographs of Road Traffic Safety Information Board with a digital camera in order to get an image and normalize bitmap image file with a size of $200{\times}200$ byte with Photo Shop 5.0. The existing True Color is made up the color data of sixteen million kinds. We changed it with 256 Color, because it has large capacity, and spend much time on calculating. We have practiced works of 30 times with erosion and dilation algorithm to remove unnecessary images. We drawing out original image with the Region Splitting Technique as a kind of segmentation. We made three kinds of grouping(Attention Information Board, Prohibit Information Board, and Introduction Information Board) by RYB( Red, Yellow, Blue) color segmentation. We minimized the image size of board, direction, and the influence of rounding. We also minimized the Influence according to position. and the brightness of light and darkness with Eigen Vector and Eigen Value. The data sampling this feature value appeared after building the learning Code Book Database. The suggested Recognition System of the Road Traffic Safety Information Board firstly distinguished three kinds of groups in the database of learning Code Book, and suggested in order to recognize after comparing and judging the board want to recognize within the same group with Nearest Neighborhood Decision Making.

Although the area of information security planning and management has gained an increased attention, not much discussion was available on the role and the impact of the board members towards a firm's security management and governance decisions. In this research, we draw on corporate governance and the organizational demography literature to conduct an exploratory empirical study on the association between the board structure of a firm and the possibility of information security breaches. Our results show that the board size, the average age/tenure and the heterogeneity of age could reduce the possibility of security breaches while the proportion of independent directors and the heterogeneity of tenure could increase it. Our findings shed lights on the important role played by the board when managing information security risks in organizations.

In this paper, I purpose one of the development methods for portable Automatic field Test Equipment(ATE) with VME form factor. Almost portable ATE have not used to standards form factor and they are connected by mechanical non-rigid general connectors and wire harnesses among the components. Furthermore, it is hard to reuse developed board. So, it decreases to reusability of developed board and it is hard to maintenance of ATE. Even those things have weakness for vibration and drop test especially in portable ATE. The XK9A1 ATE using VME form factor has environmental reliability through vibration, drop, temperature test. It consists of 5 developed board called the control board, the wire & wireless communication board, the power supply board, the load board and the mother board. It is connected by two wire harnesses between mother board and extern circular connectors. The control board send the data and address to other board though each 16-bit data and 20-bit address line. You can develop the function board what you want to using those data & address line when it comes to needing other function board.

The results of the consideration over the information board: First, most names on the information board have abstract names based on the type of features rather than the academic names of the cave terrain. Second, the role of the information media is insufficient because it only provides the name of features without the academic explanations. Third, there are a few mistakes in the information board, and some parts, which may cause academic debates, have not been described correctly.

In this paper, we implement a place information system for missing children using embedded board. In the implementation, the embedded board receives location information from GPS satellites, parsing GGA information which includes current time and location coordinates from the satellite information and sends them to the location management server. The server locates a missing child using the location information from embedded board together with server database. We implement an application program for the system. The program shows current location of a child and its moving path and browses the corresponding map from coordinates mapping.
