Binarization of number plate Image with a shadow
Seo, Byung-Hoon ; Kim, Byeong-Man ; Moon, Chang-Bae ; Shin, Yoon-Sik ;
Journal of the Korea Industrial Information Systems Research, volume 13, issue 4, 2008, Pages 1~13
In this paper, we propose a method to solve a problem in binarizing the rear number plate image captured by a camera on a moving vehicle. An image may be shadowed by the cavernous structure of the rear side of a moving vehicle and it makes us hard to get a high quality of binary image. Therefore, we first detect a shadow edge and then divide an image into the shadow part and non-shadow part by the edge. Finally, the binary image is obtained by binarizing each part and merging them In this paper, we do comparative work on a group of binarization methods including our method, the method suggested by Zheng, the method using block binarization, and the method using labeling. The result shows that our method achieves better performance than others in most cases.

Information Technology (IT) managers play an important role as a bridge between technology and business, and it is therefore important to determine what skills are required for this position. Although many previous studies have investigated the skills necessary for IT managers to perform their roles, most of these studies are based on the data collected from companies in the US. However, given the increased labor mobility in the IT industry, it is important to determine whether IT manager positions elsewhere require the same skills as the positions in the US. This study is a first step in this direction and attempts to determine whether there are any differences in skill requirements between Korean IT managers and American IT managers, and, if so, what they are.

The primary objective of his study is to investigate the factors influencing the implementation performance of K public corporation's ERP system from end user perspective. For this purpose, a research model and hypotheses are developed based on the literature reviews of IS Success Models. Data has been collected from 276 users who have used ERP system in K public corporation and the research hypotheses were tested using covariance structure model analysis. The hypotheses test results of this study are summarized as follows. Firstly, system quality has a positive influence on system usage, but information quality and service quality do not have significant influence on system usage. Secondly, all of three quality factors which are information quality, system quality, and service quality, have positive influence on user satisfaction. Lastly, both of system usage and user satisfaction have positive influence on user performance. From the analyses, this research ends with implications, as well as limitations and future research directions.

Recently security is being an important issue in almost every field of industry. This situation has affected port logistics industry deeply. Ports are now leaving operational methods that only focus on productivity, and shifting to new ones which focus on safety and customer services on the basis of it. Thus a lot of companies and institutions have offered various solutions as this issue becomes more and more intense. Among them, most typical solutions involve installing special devices to ordinary containers to improve its security, such as CSD (Container Security Device) of GE (General Electric) and eSeal of Savi Networks. On the other hand, these devices focus only on international standards or technical implementation, and this causes inconvenience to actual users like cargo owners, sea carriers, or stevedoring companies. This is considered to be due to lack of sufficient consideration on user demands. This research uses QFD (Quality Function Deployment) method for deducting system requirements in order to solve the problems of previous security devices and to develop a security system that can not only reflect the demands of the users but also considers real-world conditions. According to the QFD results, a total of 21 system CTO's were deducted under 5 categories.

Collecting and managing the sensor information through the Internet is critical to effectively manage and utilize the sensor information. The interworking technique of the sensor network and internet is required to realize the desirable condition for managing and utilizing the sensor information. Among many interworking techniques, the translation technique using the gateway had been widely studied. However, the technique which mounts IP-based Internet protocols directly on the sensor node is getting more attention recently. Particularly, IPv6 is suitable for the communication protocol for the sensor network, because its features, such as abundant address space or address auto-configuration, are well matched with the sensor network. In this paper, we design the tiny UDP/IPv6 protocol functions which are suitable for the sensor network environment, and we implemented the functions with TinyOS based nesC. After we examined the simulation results of by using TOSSIM and TinyViz, we carried out the experimental performance evaluation for the program by mounting the tiny UDP/IPv6 on the sensor node (Mote).

Recently, as managing organization's stakeholders become important, a viewpoint of corporate social responsibility (CSR) has been changed. Unlike in the past, organizations have performed CSR in their active and strategic point of view. Previous studies about the effect of social responsibility generally focused on customer response, social performance, and financial performance, and studies about the influence on business processes and organizational members are relatively not sufficient. In particular, there is few studies about the relationship among CSR, organization's innovation capability, and non-financial performance. The purpose of this study is to examine the effect of CSR to knowledge management and organizational performance by using multiple regression analysis. Specifically, from the empirical result of this study with 256 Korean finns in diverse industries including the manufacturing, we identified that CSR has positive influence on knowledge management and organizational performance.

As the information and communications market goes more uncertain, foresight activities becomes more important. A number of foresight activities, such as trend analysis, have been used to predict customer needs. However previous studies tend to lack objectivity and systematization. In this study, we suggest a meta analysis methodology which combines both top-down and bottom-up approach in order to systematize the analysis process. Secondly, we applied this approach to ICT market to identify essential future technologies. Based on the result from the meta analysis, we have constructed the future technology roadmap.

As the innovation of computer and communication technology, IT has played a role of increasing the business efficiency and offering new business opportunities. Many organizations have tried to launch IT projects, and the investment scale has been getting bigger. However, a lot of IT projects have been failed because of the difficulties of project management. Therefore, the purpose of this study is to know how the roles of project governance affect the project performance and what role of the project governance will be affected to solve the problems which might be taken place while developing the project. As the results of this study, the roles of project governance - linking, coordination, control, strategic direction, support, societal embedding, highly affect the project performance. To solve the problems which might be occurred while implementing the project, the control and the societal embedding roles playa crucial role compared to the other roles of the project governance. In other words, the roles of project governance should be utilized for the success of IT project, and the control and the societal embedding of the project governance should be modified and complemented to solve the problems which might be occurred while developing the project.

Journal of the Korea Industrial Information Systems Research, volume 13, issue 4, 2008, Pages 145~154
In this paper, we propose the pet robot control system using hand gesture recognition in image sequences acquired from a camera affixed to the pet robot. The proposed system consists of 4 steps; hand detection, feature extraction, gesture recognition and robot control. The hand region is first detected from the input images using the skin color model in HSI color space and connected component analysis. Next, the hand shape and motion features from the image sequences are extracted. Then we consider the hand shape for classification of meaning gestures. Thereafter the hand gesture is recognized by using HMMs (hidden markov models) which have the input as the quantized symbol sequence by the hand motion. Finally the pet robot is controlled by a order corresponding to the recognized hand gesture. We defined four commands of sit down, stand up, lie flat and shake hands for control of pet robot. And we show that user is able to control of pet robot through proposed system in the experiment.

This study empirically examined the structural relationships among components of interactivity, affective commitment, and components of brand equity in on-line brand community. Interactivity was conceptualized as 4 components such as mapping, personalization, responsiveness and connectedness. Components of brand equity include brand associations, brand awareness, and brand loyalty. Using a sample of 127 university students of on-line brand community members in Busan, we empirically examined the study model. The results of this study showed that components of interactivity except connectedness had a significant effect on affective commitment, which in turn, had a significant positive effect on brand associations, brand awareness and brand loyalty.
