Due to fast development of digital equipments, various information techniques have been applied to the tunneling and a decision aid system based on IT has also been used during excavation stage. A PDA based informative tunneling method is, therefore, studied in this paper and the decision aids for tunneling using digital face mapping data as well as geologic information in terms of digital data is developed. For this, wireless network, mobile computer, CDMA and digital camera have been combined to generate the digital map of the tunnel face and reinforcement or excavation pattern can be estimated based on digitalized geologic conditions. Future studies will be concentrated on the enhancement of the PDA S/W so that reinforcement method as well as the amount of reinforcements can also be stored in the same DB. Furthermore, field application of the S/W will be undertaken and a virtual reality technique will also be introduced to visualize all the tunneling work on the computer monitor.

The tunnel measurement data such as deficiency quantity, outbreak quantity, inner displacement and crown settlement are very important elements in tunnel sites under construction and obtained mostly by displacement gauge and total station. However, it is difficult and dangerous to install targets or measurement equipments on the points in tunnel construction site and also we need several persons to work in the tunnel. Non-prism total station with remote control system which is developed recently has various efficient functions for tunnel measurement. Therefore, for efficient tunnel measurement, this study suggested one person surveying system which consisted of non-prism total station and notebook PC to control total station remotely, and we evaluated the suggested tunnel measurement system. In this study, the tunnel site under construction was chosen as the test field and tunnel surveying was done by existing surveying method and suggested method separately. As result of the test, we analyzed processing time and accuracy to demonstrate the superiority of suggested one person non-prism surveying system.

The remarkable development of digital technologies and the success of 3D stereoscopic films have led to started drawing attention to stereoscopic images. The stereoscopic images have not become a passing fad in the present time unlike in the past, but have constantly showed their potentials. Unfortunately, the domestic stereoscopic images market is faced with difficulties, such as lack of the capital strength and of insufficient production infrastructure, and the production of 3D from 2D. As a result, it is not easy to produce creative stereoscopic animation contents. Therefore, in Korea, more efforts should be made in accumulating a plenty of data on production techniques. In order to make film production reflecting stereoscopy and effective stereoscopic implementation, which are necessary to produce high-quality stereoscopic contents, this thesis gave an explanation about a production technique studied on the basis of 3D graphic. Stereoscopic images are definitely one of the most promising image contents in the 21st digital contents industry. For the reason, in order to produce stereoscopic animation contents with high quality, fundamental studies on the stereoscopic images should be performed in a constant and cautions way.

By the most important media to deliver the contents on a remote instruction we commonly use audio and documents. A number of remote instruction system are trying to offer the video, but they did not acquire satisfiable results because of the limited network and width. Also, they use the general web browsers that have a lot of unspecific users access the contents. Also, they use the general web browsers that have a lot of unspecific users access the contents. Like this most systems that use the continuous media have not offer the satisfiable contents because of the network limitation. Moreover, because they use the web browser, they offer the contents having documents(web pages) only. In this paper, we propose a web-based remote instruction system on real-time using audio and documents which are the most important media for a information delivery. In addition to the system, we use a action synchronization mechanism between the web browsers. If the instructor uses web pages on his computer and explains the contents of them, the learners see the same web pages as the instructor's and listens to his voice.

This paper descbibes a fuzzy multiobjective linear programming, which is a relatively new approach in forestry in solving forest management problems. At first, the fuzzy set theory is explained briefly and the fuzzy linear programming(FLP) and the fuzzy multiobjective linear programming(FMLP) are introduced conceptionally. With the information obtained from the study area in Thailand, a standard linear programming problem is formulated, and optimal solutions (present net worth) are calculated for four groups of timber price by this LP model, respectively. This LP model is reformulated to a fuzzy multiobjective linear programming model to accommodate uncertain timber values and with this FMLP model a compromise solution is attained. Optimal solutions of four objective functions for four timber price groups and the compromise solution are compared and discussed.

In this paper, we study the inquisitive tendency in informatics textbooks for middle school students. These textbooks were written in 2009, and have been adopted in 2013 as part of the curriculum. The research is based on six textbooks, which passed qualification tests, and is mainly focused on the section 'composition and movement of information equipment', which covers contents for the student's major field of study. Romey analysis was employed to analyze inquisitive tendency in four sections - text, data, activity and evaluation. The results illustrated that some textbooks were organized in a way that exhibited a low level of inquisitive tendency for students, and took an authoritative tone. The section 'activity' showed the highest level of inquisitive tendency and the 'text' showed the lowest level. Some sections in the textbooks were found to have zero Romey measures, which stress the need for improvement.

We present the development process of a prototype CCD imaging system which is being built at Korea Astronomy Observatory(KAO) for astronomical applications. The CCD imaging system requires very low noise and high stability characteristics and is widely used for astronomical purposes from infrared to ultraviolet wavelength regions. However its system design, particularly for the controller design technique, as heart of the system, is not secured in Korea so far. The prototype electronics developed in this study consists of a signal chip controller which was implemented in an EPLD(Erasable Programable Logic Device) and an analog driver, a video processor with a LN2 cooling cryostat. A PC system was employed to control the whole system and to store the image data considering compatibility of the system. We have successfully obtained the first image in the laboratory with the prototype of this imaging system, and an image of the M15 at Sobaeksan Astronomy Observatory.
