  • This thesis intends to analyze tooth distortion by mandibular arch form by reproducing existing panorama image and reconstructed panorama image of Cone Beam CT data with the three-dimensional computer program. The diameter of tooth measured in Cone Beam CT's cross-section image and reconstructed panorama was synchronized without any big change from incisors to posteriors. But, panorama showed serious distortion as going to posteriors after showing a little distortion in incisors. The panorama reconstructed for patients' individual arch showed reduced distortion than panoramas used generally. In addition, panorama showed serious distortion from incisors to posteriors and it means that distortion is reduced in reconstructed panorama.

  • This paper discusses the threatening problem of Year 2000 (Y2K) to the banking industry. Of all steps to prepare for this big challenge, the clear understanding of the problem is always first to cope with the corning crisis. We categorize the possible issues into nine facets: (1) Potential Systemic Issues; (2) Technology Problems; (3) Technical Resources; (4) Vendor Management: (5) Supervisory Coordination and Security Issues; (6) Spillover Business Risks; (7) Operational Problems; (8) Euro Problem; and (9) Face Closure or Loss of Federal Deposit Insurance. We believe that each or these nine issues must be dearly recognized and appropriately prepared by those bankers who want to avoid the disaster they have never experienced.

  • This study aims to reveal the effects of shoe size room on the inner environment of shoes by examining the changes of footskin temperature, temperature and humidity of the shoes, and psychological responses. The following conclusions were made: 1. Skin temperature had significant differences according to shoe sizes in the inner foot parts (right/left) and the outer foot part (left). As time went, skin temperature was distributed as follows: Type A > Type C > Type B. 2. Skin temperature appeared in the following order: instep > inner foot > outer foot. 3. The temperature within the shoes had significant differences: Type A > Type C > Type B. But no significance was recognized in the humidity within the shoes: Type B > Type C > Type A. 4. Some significance was noticed in the psychological responses of size fitness and comfortableness. In size fitness, Type B was responded to be fitting, Type A little small, and Type C rather big. Moisture had similar changes according to three shoe sizes, but humid was the response as time went. Comfortableness appeared in the order of Type C > Type B > Type A.

  • TV-Anytime is an XML-based standard for description of PVR and digital broadcast services. It is referenced by many standards of digital broadcast service for their schemas and delivery protocols of contents guide. Although its readability and extensibility, TV-Anytime has a big problem which generates massive documents due to its text-based description method. Therefore, various encoding algorithms have been proposed to reduce the size of XML documents. This paper proposes efficient metadata encapsulation architecture based on the optimization information generated at server-side to minimize XML documents. Advanced indexing method is also proposed to reduce resources needed to encapsulate indices and to receive metadata with fast and explicit mechanism.

  • This paper describes novel scheme of a gray scale capacitive fingerprint image for high-accuracy capacitive sensor chip. The typical gray scale image scheme used a DAC of big size layout or charge-pump circuit of non-volatile memory with high power consumption and complexity by a global clock signal. A modified capacitive detection circuit of charge sharing scheme is proposed, which uses DLC(down literal circuit) based on a neuron MOS(vMOS) and analog simple multiplexor. The detection circuit is designed and simulated in 3.3V, $0.35{\mu}m$ standard CMOS process. Because the proposed circuit does not need a comparator and peripheral circuits, a pixel layout size can be reduced and the image resolution can be improved.

  • The propose of this study is to understand the phenomenon of radiation and comparison of analysis of two methods. One is analysis method of same-time data and the another is analysis method of rank data. We confirmed that two methods of correlation analysis had the effectiveness and suitability. The followings are main results from this study. 1) The seasonal correlation coefficient of long and short-wave radiation is higher in winter than in summer because of high humidity in the summer season can makes easily cloud in the sky locally. 2) According to analysis method, there is big difference in correlation coefficient from 0.494(Analysis method of same-time data) to 0.967(Analysis method of rank data) with short-wave radiation by the location during summer. These results have significant value in solar radiation research and analysis. It has explored a new way for solar radiation research of analysis method as well.

  • In the fourth industrial revolution represented by hyper-connected and intelligence, cloud computing is drawing attention as a technology to realize big data and artificial intelligence technologies. The proliferation of cloud computing has also increased the number of threats. In this paper, we propose one way to effectively monitor to the resources assigned to clients by the IaaS service provider. The method we propose in this paper is to model the use of resources allocated to cloud systems using ARIMA algorithm, and it identifies abnormal situations through the use and trend analysis. Through experiments, we have verified that the client service provider can effectively monitor using the proposed method within the minimum amount of access to the client systems.
