지식정보사회로의 변화가 점차로 심화되면서, 기존의 법 이론으로서는 설명하기 어려운 여러 가지 새로운 법적 현상이 나타나게 되었다. 디지털, 정보, 네트워크 등 정보사회의 특징은 아날로그, 유체물, 소유에 중점을 두고 있는 현재의 법 원리에 근본적인 변화를 요구하고 있다. 이에 정보 홍수 속에서 의사소통과 법 해석의 문제, 기본 권리, 무체물의 재산성, 액세스에서의 권리성 등 정보사회에 대한 법 이론적 논의가 필요하게 되었다. 본 고에서는 정보보호라는 차원에서 현행 우리 헌법에서 정보보호문제가 어떻게 다루어지고 있는 지에 대해 살펴보고, 정보보호관련 법규들을 우리 헌법상의 국민의 기본권으로서의 전체적인 시각에서 개괄적으로 고찰하여 보고자 한다.

최근 건설프로젝트가 대형화 복잡화됨에 따라 건설산업의 안전사고 재해자수는 매년 증가추세를 보이고 있다. 각 건설사에서 개발되어 활용하고 있는 건설안전관리시스템의 형식적인 운용과 참여자들에게 시각적인 자료 제공의 미비로 이해도가 떨어지는 시스템을 사용하고 있는 것이 주요 원인으로 분석된다. 따라서 최근 부각되어지는 증강현실시스템(Augmented Reality, AR)을 이용하여 실제 현장과 동일한 환경에서 시각화된 3D시뮬레이션을 통하여 사용자 이해도와 현장감을 높일 수 있는 시스템 개발이 요구되어진다. 본 연구에서는 건설안전관리 시스템의 효율적인 의사소통 지원이 가능하도록 개선된시각화 기술을 적용하여 "증강현실 기반 안전관리시스템"의 인터페이스 구성을 제안하였다. 이를 위해 건설안전관리의 이론적 고찰과 시스템을 분석하고, 시각화 개선을 위한 증강현실시스템을 분석하였다. 이를 통해 도출된 시각화 화면 구성요소를 조합하여 "증강현실기반 안전관리시스템의 안전대책 시뮬레이션 VIEW"를 제안하였다.

In order to analyze textbooks from a discursive approach, the purpose of this study is to structuralize an analytic framework based on previous literature review and apply it to analyzing the meanings and their syntheses developed by words and visual mediators appeared in the definition of graph in first-year middle school textbooks. The discursive approach consists of the communicational approach developed by Sfard(2008) and the systemic functional linguistics developed by Halliday(1985/2004). In this study, ideational meta-functions for ideational meanings and interpersonal meta-functions for interpersonal meanings were employed to analyze the meanings produced by words and visual mediators in textbooks, whereas textual meta-functions for textual meanings were used for analyzing the synthesized relationships between words and visual mediators. Results show that first, density in mathematical discourse was very high and subjects in mathematical activities were ambiguous in the ideational meanings of words, and behavior aspect was more emphasized than thinking aspect in the interpersonal meanings of words which request student participations. In the case of ideational meanings of visual mediators, there was a lack of narrative diagrams, whereas there were qualitative differences in the case of offer. Second, there was a need for promoting a wide range of diverse synthetic relationships between words and visual mediators for developing enriched mathematical meanings through the varying uses like specification, explanation, similarity, and complement. These results are so important that they provide a new analytic framework from a discursive approach to textbook analysis because not only words, but also visual mediators are analyzed as tools for producing meanings in mathematics textbooks and their synthetic relationships are also examined.

A prototype needs to show the requirements of the users and help them understand better. These prototypes are useful in a variety of industries. But most existing prototypes depend on the visual representation. This method of visual expression has a limitation, which can't express the detailed contents. This paper suggests an expression method of linguistic formation as an alternative. The prototype of linguistic expression can demonstrate the detailed contents of the requirements, keep a good communication among those who are related to the project, and allow them to deal with a large number of possible problems which may happen from the developing process. As it's also easy to make the developing process documented, the prototype will be helpful to improve the software development.

This study analyzed the visual images covering 'weather' and 'weather forecast' in elementary science textbooks from the Syllabus Period to the 7th national curriculum from the socio-semiotic perspective. The results showed that most of the visual images were 'realistic' which were descriptive of real world phenomena. This means that most of the visual images in elementary science text were familiar to students in every curriculum period. The power relationship in communication between images and students was very complex. The visual images in elementary science textbooks include few geometrical and alphanumeric code in every curriculum period. This study provides a new framework to interpret amount of information, functions of information, structures, and social meanings of visual images. It could be also a beginning stage to introduce the socio-semiotic perspective into choosing visual images for next science textbooks.

When restoring their anterior dentition, patients become more demanding on esthetics compared to posterior region during treatment planning phase. Digital Smile Design (DSD) procedure is performed in presentation software and digital photographs. This can widen diagnostic visualization and aid in transferring information between clinician, patient, and technician. This case presented is that of patient with dissatisfaction of his anterior old restoration. Retreatment procedures were carried out in two different manners: (1) using DSD protocol for diagnosis, smile simulation, communication and fabricating interim and definitive prosthesis by totally digitized workflow. (2) Using diagnostic wax-up for smile design and fabricating restorations by conventional workflow. Comparing two methods, DSD was easier to communicate between the dental team than the diagnostic wax-up method. But the final result obtained failed to meet total esthetic factors. Therefore, to obtain predictable esthetic results, more advanced design tool would be needed, including consideration of various esthetic factors besides successful communications.

Students have to investigate, experiment and inquire using the manipulative materials and real-world thing for studying Geometry. Manipulative materials activities encourage to understand mathematical concept and connection of symbol. Experiment activities using the computer focused the student's intuitive and inquisitive activities because of visualization of an abstract mathematics concept. This study developed a workbook through the use of manipulative materials and computer for operating and experimenting, and suggested a method for inquiry of geometrical properties and proved an effect. Manipulative materials-experiment activities was proven effective to middle level and lower level students in understanding the geometrical properties, and was proven effective to high level and lower level students when it comes to mathematical communication ability. When students operate, at first, they have to know about the feature and information of the materials, and the teacher has to make an elaborate plan and encourages the students to discuss about this.

Electronic BBS (bulletin board system) Ins been widely recognized as an appropriate medium for exchanging ideas and sharing information asynchronously. The communication ability if BBS is the main reason for utilizing it as a tool for collaborative learning. Researchers in the community reported a number if findings regarding the educational utilization if BBS recently. In this paper, we propose a qualitative method to measure communication activities using BBS so that the complex discussion behaviors of participants can be understood analytically. We propose characteristic vectors to describe discussion behaviors of groups and individuals, which can be conveniently used for characterizing and comparing discussion groups as well as individuals. The interactivity model representing interactive activities shows graphically the degree of inter activity if discussion groups as well as individuals. Also, time dependent measurements are investigated to analyze discussion activities with time. Experiments on the proposed measurements conducted on the Web-based discussion project using BBS demonstrate how measurements can be carried out, how characteristic vectors and inter activity model can be constructed and used.

소아의 경우 의사소통이 불완전하므로 자신의 건강 상태를 정확히 표현할 능력이 없거나 떨어진다. 따라서 소아에 대한 의학적 판단에 기초한 기술적 방법의 제시가 필요하다. 이를 위해 본 논문에서는 소아 건강 상태를 측정할 수 있는 한방 4대 진단 방법 중에서 망진을 이용하여 소아 질환 진단기기를 개발하고자 한다. 특히 호흡과 관련된 중요 인체 부위로 폐 질환에 대한 망진기기를 개발하기 위한 방법을 제안하고자 한다. 이를 위해 본 논문에서는 소아 얼굴을 입력 받아 얼굴 영역에 대한 분할을 하고 폐장과 관련된 명당 부위를 추출한다. 추출한 소아 영상에서 색상 분석을 행하여 객관적이며 시각적인 데이터를 가지고 소아 폐질환 진단기기를 개발하고자 한다. 최종적으로 소아 폐질환자와 정상인의 비교, 분석을 통해 제안한 방법의 유용성을 입증하고자 한다.
