Many organizations’ employees and contractors use enterprise smartwork technologies to perform their tasks from external locations. Most smartworkers use remote access technologies to interface with an organization’s non-public computing resources. The nature of smartwork and remote access technologies generally places them at higher risk than similar technologies only accessed from inside the organization, as well as increasing the risk to the internal resources made available to smartworkers through remote access. Therefore, in this paper, we will analyze security vulnerability that can occur in smartwork environment, then we proposed smartwork framework that provide secure access control.
Remote user authentication methods has been continuously developed on the basis of the various researches. In 2008, Bindu et al. pointed out that Chien et al.'s protocol has security weaknesses in the man-in-the-middle attack and the insider attack. And then Bindu et al. proposed new protocol. However Bindu et al.'s protocol was found some weaknesses about strong masquerading user/server attack, DoS attack and restricted reply attack. In this paper, we propose an smartcard-based remote user authentication protocol with improved security functions which can remove vulnerabilities of Bindu et al.'s protocol.
Most of the existing character region extraction methods have focused on 2D character regions in video. However, there are also a lot of atypical characters in video and natural images, and they often have significant meanings. In this paper, we propose a method to extract atypical character regions using a graph theory. We first perform a preprocessing for character extraction and segments each region. We then obtains atypical character regions from segmented regions by using a graph algorithm. Experimental results show that the suggested system extracts atypical characters effectively.

Capacitors with wrinkle or gap type electrodes are proposed to improve the performance of embedded PCB(Printed Circuit Board). Capacitor with the wrinkle type electrodes represents more higher(about 40%) capacitance density than that of conventional embedded capacitor. And capacitor with gap type electrodes represents resonant frequency of 4GHz but a conventional embedded capacitor just represents resonant frequency of 1GHz. Also it is confirmed that resonant frequency can be changed by the gap size. Capacitor with gap type electrodes in which dielectric gap of 50㎛ showed capacitance density of 55. This value is higher than that of conventional embedded capacitor. Embedded inductor with switching transistors for inductance variation shows good quality factor Q.
The purpose of the paper is to show that we are to present suggestions to prevention the crisis of the companies through the case research of major accidents in the area of Enterprise Crisis Management. The wide range of major accidents were collected from the domestic and foreign companies. The study showed several critical results. First, every crisis harms the company trust seriously. The ‘unethical’ showed the great negative influences followed by accident, natural disaster, rumor and malevolence. Second, appropriate response strategy was helpful for rebuilding brand trust remarkably. Apology was a most effective response to all crises and no response and denial were badly response strategies to all crises. Explanation and justification have effects on natural disaster and unethical crisis. This study helps crisis managers to manage crises effectively when the company want to select proper crisis response strategies.
As the living standards have improved, the healthcare becomes a major concern of the people and organizations such as schools and companies. The mass health examination is known to be helpful for early detection of diseases, however, there is a limitation that the examination results are generally used to simply identify specific symptoms and diseases. To make full use of the mass health examination result, this paper proposes an intelligent feedback system which can evaluate the individual risk for symptoms and diseases not identified in the examination results and provide the health-related advices. To this end, the hierarchical clustering analysis, one of the common data mining techniques, is deployed to extract the characteristics of the target examinee group. Our system is applied to analyze the mass dental examination result of high school students.
