Yun, Sung-Hyun ;
Journal of the Korea Convergence Society , volume 2, issue 1, 2011, Pages 1~6
The wide use of mobile devices such as smart phones makes the mobile commerce industry be growing-up rapidly. In mobile commerce security, how to secure a copyright of mobile contents and how to distribute it are of major concerns. The user can carry the smart phone regardless of the places. Thus the utilization of it is very high than that of personal computers. The USIM(Universal Subscriber Information Module) inserted in the smart phone binds the user with the device. This means that the smart phone can be used to represent the owner's identity. In this paper, we develop the mobile ID based digital signature scheme. We create the mobile ID by combining USIM with the user's random secret value. In addition, undeniable property of our signature scheme can make ID based applications such as mobile voting and mobile content distribution be possible with the smart phone.

Informations of multimedia centering in the images, are combined acoustic and letter, etc. Although the network advances and the capacity of the storage media extends, these huge informations will not be able to accommodate. From meaning which is like this, International standards for the compression and a multiplexing of image, acoustic and voice H261 where admits standard, JPEG, JBIG, MPEG-l, MPEG-2, MPEG-4 and H263, G series etc, are core techniques of multimedia. At initial step of the base technique which creates the base of like this multimedia service time, we developed the real-time MPEG-4 transmission systems to provides real-time MPEG-4 multimedia services. This system means becomes the base technique which hereafter is developed and is applied various system. This system Will be able to apply from a videoconference, a building protection system and a VOD video system to use the Internet. And, They, the image sensing, embedded linux, and MPEG4 software, will become sourceful technique to develop the different system.

The questionnaire survey using the Center for Epidemiology Studies-Depression Scale(CES-D) was conducted in the rural people. The subjects were 226 individuals, living in the rural area. The results of this study were as follows. In this study, the prevalence of depression was 15.0% in all and 18.3% in the elderly. The prevalence rate was higher in non educational, widowhood, higher income group. The prevalence rate was lower in the group of having good health status, having no chronic disease, low stress level. In the multiple logistic regression analysis, significant predictors of the depression were stress level whereas there was no relation with other factors. Based on the above findings, this study suggests that these risk factors of depression should be taken into consideration for the comprehensive mental health programs for the people living in the rural area.

Journal of the Korea Convergence Society , volume 2, issue 1, 2011, Pages 31~36
This study was performed to investigate the problems of using asbestos for dental technicians. Samples for analysing were sampled by personal sampler in 40 sampling points of 10 dental laboratories in Daegu city from December 2010 to January 2011 and counted with phase contrast microscopy. The results were as follows: 1. Asbestos concentration(geometric mean) of 40 sampling points in 10 dental laboratories was 0.0061 f/cc and it was under recommended industrial and indoor air standard, but the concentration of asbestos in only two dental laboratories was over indoor recommended standard. 2. The concentration of asbestos in processing room and burnout room was 0.0099 f/cc and 0.0037 f/cc, respectively. 3. The mean concentration(GM) of asbestos by kinds of casting ring liners was 0.0159 f/cc in dental laboratories using industrial asbestos, 0.0104 f/cc in them using asbestos containing ring liners, and 0.0026 f/cc in them using non-asbestos ring liners. Casting ring liners using in dental laboratories should be substituted with non-asbestos liners, because most of dental laboratories were using asbestos containing ring liners and a few of them showed higher concentration than recommended standard.
