국가기본도는 국가공간정보의 기준이 되는 공간정보로서 그 가치와 역할이 매우 중요하다. 그러나 현행 국가기본도인 1/5,000 수치지도는 품질 및 정확도의 한계로 인하여 기초 공간정보로서의 역할을 충분히 수행하지 못하고 있는 실정으로 이에 대한 보완 방안이 필요한 시기이다. 이에 본 연구에서는 현 1/5,000 국가기본도의 고도화 방안을 제시하고자 GSD 0.25m 디지털 항공사진으로 제작 가능한 수치지도 지형 지물 항목을 선정하고, GSD 0.25m 디지털 항공사진을 이용한 최적 수치지도 제작 실험을 통해 수치지도 제작 최적 방법을 정립하였다. 또한 GSD 0.25m 디지털 항공사진으로 제작된 수치지도의 정확도 및 활용성 분석을 수행하였다. GSD 0.25m 디지털 항공사진을 이용한 수치지도 제작 기준을 정립하기 위하여 판독력 분석을 수행하여 대분류 9 개, 중분류 31개, 소분류 509개의 지형 지물 항목을 선정하였으며, 수치지도 제작 방법에 따른 수치지도 제작 실험을 수행하여 입체도화 방법을 수치지도 제작 최적 방법으로 선정하고, 최적 공정을 정립하였다. 본 연구 성과를 이용하여 GSD 0.25m 디지털 항공사진을 이용한 수치지도 시범 제작을 수행한 결과 기존 1/5,000 수치지도에 비해 약 2배의 수평 및 수직위치 정확도를 확보할 수 있었으며, 지형 지물의 상세한 묘사가 가능하여, GSD 0.25m 디지털 항공사진을 이용하여 국가기본도를 제작할 경우 신뢰성 있는 공간정보를 제공으로 대국민 서비스 만족도 향상과 국가기본도 고도화를 추진할 수 있을 것으로 판단된다.

DS-CDMA is used to widely spread spectrum for a cellular mobile digital communication that maximizing users- capacity at the limited frequency bandwidth, solving technical matters with the channel. Especially, the capability of a spread spectrum receiver relied on fast code acquisition time at the demodulation. In this paper, we considered that fast code acquisition time when a spread spectrum system is designed, and existed code acquisition system set up one code epoch on a position at initial processing, but the proposed code acquisition system improved that two code epoch are set up at the same time, therefore code acquisition time is diminished in effect. The structure modeling to VHDL language. Its synthesized the synthesized and, is implemented FPGA chip

Objective: This study compared occlusal contact areas of ideally planned set-up and accomplished final models against the initial in class I and II molar relationships at finishing. Methods: Evaluations were performed for 41 post-orthodontic treatment cases, of which 22 were clinically diagnosed as class I and the remainder were diagnosed as full cusp class II. Class I cases had four first premolars extracted, while class II cases had maxillary first premolars extracted. Occlusal contact areas were measured using a three-dimensional scanner and RapidForm 2004. Independent t-tests were used to validate comparison values between class I and II finishings. Repeated measures analysis of variance was used to compare initial, set up, and final models. Results: Molars from cases in the class I finishing for the set-up model showed significantly greater contact areas than those from class II finishing (p < 0.05). The final model class I finishing showed significantly larger contact areas for the second molars (p < 0.05). The first molars of the class I finishing for the final model showed a tendency to have larger contact areas than those of class II finishing, although the difference was not statistically significant (p = 0.078). Conclusions: In set-up models, posterior occlusal contact was better in class I than in class II finishing. In final models, class I finishing tended to have larger occlusal contact areas than class II finishing.

This appendix deals with the Korean air interface standard, TTA-62, for CDMA Mobile Systems, (CMS) [1]-[2]. The standard has been set up by Telecommunications Technology Association (TTA) which is a standardization organization in Korea [3]. This standard is an important specification that should be determined prior to the development of a digital cellular system. The CMS has been developed on the basis of this standard and the papers published in this special issue are the results of the CMS development. This appendix also describes the technical commonality of these papers. It covers the outline of the air interface and protocol specifications. The outline includes its major characteristics, radio protocol architecture, functionalties, and call processing. A comparison is also given between TTA-62 and IS-95[4], a North American digital cellular standard.

A comprehensive review on the technical standards about human factors (HF) design and software reliability maintenance for digital instrumentation and control (I&C) and human-machine interface technology (HMIT) in Japanese light water reactor nuclear power plants (NPPs) was given in this paper mainly by introducing the relevant activities at the Japan Electric Association to set up many industrial standards within the traditional framework of nuclear safety regulation in Japan. In Japan, the Fukushima Daiichi accident that occurred on March 11, 2011 has great impact on nuclear regulation and nuclear industries where concerns by the general public about safety have heightened significantly. However for the part of HF design and software reliability maintenance of digital I&C and HMIT for NPP, the author believes that the past practice of Japanese activities with the related technical standards can be successfully inherited in the future, by reinforcing the technical preparedness for the prevention and mitigation against any types of severe accident occurrence.

For successful surgery-first approach, accurate prediction of skeletal and dental changes following orthognathic surgery is essential. With recent development of digital technology using computer-aided design/computer-aided manufacturing (CAD/CAM) technology, attempts to provide more predictable orthodontic/orthognathic treatment have been made through 3D virtual surgery and digital tooth setup. A clinical protocol for the surgery-first orthognathic approach using virtual surgery is proposed. A case of skeletal Class III patient with facial asymmetry treated by the surgery-first approach using digital setup and virtual surgery is presented. Advantages and limitations of applying CAD/CAM technology to orthognathic surgery are discussed.
