Recently, many troubles about the right of light have been arising ceaselessly as taller and more dense the buildings have been in the urban. The present time, the right of light is not stipulated legally. For solving above problems, there spend so too much lawsuit expenses and time on the damages about construction stopped and delayed, according to subjective decisions instead of scientific and rational solutions. The past studies of the right of light weren't based on the analytic data and depend on the simple view of point. So, those of studies gave trust to people hardly, only were treated as the ways on the decision about construction among non-engineers. Therefore, this paper studies the efficient solution of problems about the right of light through analysis about mass of sunlight according to season and the hour using a simulation technique on the civil construction.

Tangible user interfaces have been developed in the area of Human-Computer Interaction for the last decades, however, the applied domains recently have been extended into the product design and interactive art. Tangible User Interfaces are the combination of digital information and physical objects or environments, thus they provide tangible and intuitive interaction as input and output devices, often combined with Augmented Reality. The research developed a design guideline for tangible user interfaces based on key properties of tangible user interfaces defined previously in five representative research: Tangible Interaction, Intuitiveness and Convenience, Expressive Representation, Context-aware and Spatial Interaction, and Social Interaction. Using the guideline emphasizing user interaction, this research evaluated installation in a science museum in terms of the applied characteristics of tangible user interfaces. The selected 15 installations which were evaluated are to educate visitors for science by emphasizing manipulation and experience of interfaces in those installations. According to the input devices, they are categorized into four Types. TUI properties in Type 3 installation, which uses body motions for interaction, shows the highest score, where items for context-aware and spatial interaction were highly rated. The context-aware and spatial interaction have been recently emphasized as extended properties of tangible user interfaces. The major type of installation in the science museum is equipped with buttons and joysticks for physical manipulation, thus multimodal interfaces utilizing visual, aural, tactile senses etc need to be developed to provide more innovative interaction. Further, more installation need to be reconfigurable for embodied interaction between users and the interactive space. The proposed design guideline can specify the characteristics of tangible user interfaces, thus this research can be a basis for the development and application of installation involving more TUI properties in future.

This paper describes the feasibility and reliability verification of installing a protective structure to protect attack periscopes. The attack periscope is the critical equipment of a submarine to enable the user to monitor surface and air activity, collect navigational data, and detect and identify targets. The attack periscope provides target information acquired through TV, IR camera, and laser range finder to the combat system. In the product improvement program, the upper part of the masts was exposed to the outside of the sail because the existing attack periscope was replaced with a new one. On the other hand, the head sensor can be damaged by floating objects, such as fishing nets, during sea navigation. Therefore, the installation of a protective structure for an attack periscope improved the equipment operation performance. The feasibility and reliability of the installation of the protective structure were verified by examining the influence of URN.

This paper discusses about the development of a visual sensor that can be installed in an automatic mooring device to detect the berthing condition of a vessel. Despite controlling the ship's speed and confirming its location to prevent accidents while berthing a vessel, ship collision occurs at the pier every year, causing great economic and environmental damage. Therefore, it is important to develop a visual system that can quickly obtain the information on the speed and location of the vessel to ensure safety of the berthing vessel. In this study, a visual sensor was developed to observe a ship through an image while berthing, and to properly check the ship's status according to the surrounding environment. To obtain the adequacy of the visual sensor to be developed, the sensor characteristics were analyzed in terms of information provided from the existing sensors, that is, detection range, real-timeness, accuracy, and precision. Based on these analysis data, we developed a 3D visual module that can acquire information on objects in real time by conducting conceptual designs of LiDAR (Light Detection And Ranging) type 3D visual system, driving mechanism, and position and force controller for motion tilting system. Finally, performance evaluation of the control system and scan speed test were executed, and the effectiveness of the developed system was confirmed through experiments.

This paper describes the result of study on measurement of displacement of structure by means of non-contacting method, close-range digital photogrammetry using digital camera. To apply close-range digital photogrammetry to displacement measurement of structure, correction of lens distortion that interferes geometrical analysis has been carried out and then measuring displacement was performed on load regulated-rahmen. For enhanced applicability of displacement measurement, MIDAS which is a structural analysis program was used for modeling and the result was taken from comparative analysis. As a result of the study, it is showed that close-range digital photogrammetry could supplement several weaknesses of LVDT and cable displacement meter and, especially, economy in the perspective of measuring time could be realized. Close-range digital photogrammetry using digital camera can be applied to the area where requires visual analysis such as 3D modeling of structure, profile replication of measurement of structure as well as measurement of displacement of structure.

상업간판은 단순한 광고목적 외에 도시의 시각이미지를 구성하는 도시환경구성요소 중 하나이다. 또한 건축물의 주요한 구성부분이며 주민에게는 환경적 즐거움을 주어야 하는 의무가 있으며 보행자로 하여금 강제적으로 주목을 끌게 해야 하는 상업적 목적을 가지고 있다. 그러나 본래의 목적과 달리 하나의 도시환경저해요소로서 문제점을 유발하기도 한다. 이러한 문제점들을 시정하기 위한 주민과 자치단체의 상업간판 환경개선을 위한 시도와 이에 따른 결과를 살펴보면서 환경개선을 위한 시도가 결과적으로 주민과 도시환경 모두에게 어떠한 영향을 끼쳤는지를 살펴보았다. 현재 한국의 간판게시규정은 중앙집권적 규율하의 기본규정과 비효과적인 부처간의 상이한 규정 및 하급세부규정의 미비에 기인하여 상업간판의 난립상황을 초래하였다. 아울러 살펴본 일본, 미국, 프랑스에서 적용하고 있는 기본규정도 한계가 있음을 살펴보았으며 따라서 어떠한 개선방향이 주민과 자치단체 양자에게 이익을 주고있는지를 살펴보았다. 효과적인 간판설치규정의 제정은 불가능하지만 규정은 제정하되 무엇보다 자발적인 주민들의 참여와 건축가, 사용자, 자치단체 사이의 주의로운 조화가 필요함을 살펴보았다.
