Purpose : To develop a new subtraction program for registering digital periapical images based on the correspondence of anatomic structures. Materials and Methods: The digital periapical images were obtained by Digora system with Rinn XCP equipment after translation of 1-16 mm, and rotation of 2-20° at the premolar and molar areas of the human dried mandible. The new subtraction program, NIH Image program and Emago/Advanced program were compared by the peak-signal-to noise ratio (PSNR). Results : The new subtraction program was superior to NIH Images program and Emagol Advanced program up to 16 mm translation and horizontal angulation up to 4°. Conclusion: The new subtraction program can be used for subtracting digital periapical images.

In the contemporary, all social shifts as well as the fields of design have been changed much faster than past. And continually it will be changed in the future. In this situation, futuristic design will be much more important paradigm than now. Emotion and digital can be key issues in the futuristic design paradigms. Karim Rashid is one of most famous futuristic designers, and all his works are expressed emotion and digital. Also he uses various factors to express futurism such as curved line, futuristic colors, special materials, and so on. In the future, we will live in the emotion and digital culture age. According to social shifts, our life should be change with Futurism. Therefore his role will be more important, and he has to consider relationship between men and their surroundings as he designs all his work's range, specially housing design.

본 총설에서는 디지털 커뮤니케이션 환경에 나타나는 메이크업 트렌드에 관한 이론 고찰을 통해 관련성과 특성을 파악함으로써 관련업계 및 연구를 위한 기초 자료를 제공하는 데 있다. 본 연구를 통해 첫째, 디지털 커뮤니케이션 환경의 사회 문화적인 특징으로는 상호작용성, 기술지향성, 감성지향성, 시공간의 혼재성으로 도출할 수 있었다. 둘째, 메이크업에서 전개되고 있는 트렌드의 유형은 상호작용성, 가상성, 유희성, 이동성으로 도출할 수 있었다. 셋째, 디지털 커뮤니케이션 유형이 채택하는 양상은 개방적이고 수평적인 사고를 중심으로 절충적인 혼합을 통해 과거에 있어왔던 스타일이나 장르와의 혼합과 병치로 나타났다. 넷째, 디지털 커뮤니케이션 환경으로 인한 트렌드가 메이크업 트렌드와의 완전한 일치는 일어나지 않았지만 인간의 외형미를 표현하는 전체 틀 속에서 동질성과 유사성을 바탕으로 상호작용을 통해 유기적으로 작용하고 있다는 것을 알 수 있었다. 디지털 커뮤니케이션 환경이 생성되면서 사회가 특정한 국가 간의 경계를 넘어선 다양한 장르의 혼합 및 붕괴의 복합적인 디지털 사회의 현상으로 형성되어 하이브리드 경향이 메이크업 트렌드에서 보여지고 있다.

Purpose : The purpose of this experiment was to evaluate the diagnostic ability of a CCD-based digital system (CDX-2000HQ) in the detection of incipient dental caries. Materials and Methods : 93 extracted human teeth with sound proximal surfaces and interproximal artificial cavities were radiographed using 4 imaging methods. Automatically processed No.2 Insight film (Eastman Kodak Co., U.S.A.) was used for conventional radiography, scanned images of conventional radiograms for indirect digital radiography were used. For the direct digital radiography, the CDX-2000HQ CCD system (Biomedisys Co. Korea) was used. The subtraction images were made from two direct digital images by Sunny program in the CDX-2000HQ system. Two radiologists and three endodontists examined the presence of lesions using a five-point confidence scale and compared the diagnostic ability by ROC (Receiver Operating Characteristic) analysis and one way ANOV A test. Results: The mean ROC areas of conventional radiography, indirect digital radiography, direct digital radiography, and digital subtraction radiography were 0.9093, 0.9102, 0.9184, and 0.9056, respectively. The diagnostic ability of direct digital radiography was better than the other imaging modalities, but there were no statistical differences among these imaging modalities (p > 0.05). Coclusion : These results indicate that new CCD-based digital systems (CDX-2000HQ) have the potential to serve as an alternative to conventional radiography in the detection of incipient dental caries.

Digital designs that appear in the three-dimensional virtual space by the digital type are designed as there is not an image created with an organic artificially generated (Creation) and representation (Modifying), developed by the specific environment given. The advanced digital design will produce a result with an algorithm according to a mathematical operation and the environment and has the nature of generating the real world, changes, development and affinity (Genetic Process). The digital design process is largely defined by a set of processes that are consistently designed to integrate form of creation, reproduction, proceeds in three steps, while the manufacture and assembly as a form of maintenance as possible the intended form of control data from the concept of building. By Joris Laarman 3D printer design is a simulation created by the digital process by the various algorithms and design achieved through the development of 3D printers, such as new materials and MX3D. From the mold production of a complex whole by using a robot and other digital production tool extracts a variety of forms.

The purpose of this study is to propose 3D art make-up design process by reproducing real objects through preliminary digital drawing with Photoshop (Photo Shop CS4.0, Adobe, USA) and using special make-up that has never been done previously, and produce creative problem solving plan to make concrete expanding thoughts and ideas. As for this study method, this study was composed of preliminary study, literature study by book examination and positive study on design process that performed preparatory work and reproduced real objects. Real case study by art make-up design process can improve effective design expressing ability by utilizing special make-up, diversify techniques, extend expression areas by materials, and create unique design. In addition, preliminary work by digital drawing, a process to predict real object work in advance, could reduce time and cost while improving work skill for work production, raise design accuracy and make easy the modification of idea. This study is anticipated to activate digital make-up by various digital techniques including Photoshop.

도서관이 장서를 디지털화 하고자하는 데에는 크게 두 가지의 목적을 가진다. 첫째는 장서의 보존에 역점을 두어 아날로그 장서를 디지털장서로 변환함으로써 기존 장서를 영구 보존하고자 함이며, 둘째는 기존장서를 디지털화함으로써 이용자에게 편리한 접근서비스를 제공하고자 한다. 본 논문은 대학도서관이 장서의 일부로서 디지털장서를 구축하고자 할 때 고려해야 할 점을 살펴보았다. 디지털도서의 목적과 의미를 개관하였으며 디지털장서 개발정책의 기준을 고찰하였다. 대학도서관의 디지털장서 개발정책 수립 시 고려해야 할 요인들을 논의하였다. 디지털 대상도서 선정기준, 디지털장서의 적정크기, 지식통제 및 자료관리의 필요성, 공동 디지털장서 개발사업의 중요성 등을 살펴보았다. 대학도서관의 디지털장서 개발정책은 전통적인 장서개발정책과 통합되어야 하며 대학도서관의 디지털장서가 연구와 강의를 지원하는 대학의 사명을 충족시킬 수 있는 전략적인 장서로 구축되어야 함을 강조하였다.

In the scientific research, the object of research is a complex of legal relations, which are formed by the use of modern digital technologies. The subject of this work is the novelties of Ukrainian and foreign legislation, norms of international law aimed at regulating social relations in the field of digital rights, as well as doctrinal provisions and materials of law enforcement practice. Within the framework of this work, two types of digital rights are distinguished, those that exist in the law of Ukraine, and the issues of law that apply to legal relations, regarding the turnover of each of them, are considered. Examples of law applied in foreign countries are given for comparison. On the basis of a comprehensive study of the legal framework and positions of scientists, the prospects for the development of legal regulation of digital rights were noted.
