Currently, in spite of continual efforts, the information utility of the construction industry does not communicate well with other industries. This problem arose from mistaken and misguided efforts on the parts of the construction industry because it left out of consideration construction characteristics which are at the center of construction, and this information system was directly introduced and operated from outside the industry. There were also other mistakes that the existing information systems disregarded in trying to fix these problems. Therefore, this study describes a new process, which proposes to build and utilize a Bridge Management System using the mobile internet concept, to solve the problems of the existing construction information management system.

In this study, a model is developed to predict emission factors, which aims to objectively evaluate the impact of transport projects on air quality. Two emission prediction models for the years of 2015 and 2030 are developed using the historical trends in vehicle aging and vehicle deterioration factors. The analysis results show that the emission factors under the operating speed of 30km/h for the year 2030 are 5~37% and 2~83% less than those used in the current studies for passenger cars and bus/trucks, respectively. The statistically validated experiment results demonstrate the applicability of the proposed model to evaluation of the impact of transport policies on air quality.

In this paper, we proposed a tangible RealBook based on the interface of TouchFace-V which is able to recognize multi-touch and hand gesture. The TouchFace-V is applied projection technology on a flat surface such as table, without constraint of space. The system's configuration is addressed installation, calibration, and portability issues that are most existing front-projected vision-based tabletop display. It can provide hand touch and gesture applying computer vision by adopting tracking technology without sensor and traditional input device. The RealBook deals with the combination of each advantage of analog sensibility on texts and multimedia effects of e-book. Also, it provides digitally created stories that would differ in experiences and environments with interacting users' choices on the interface of the book. We proposed e-book that is new concept of electronic book; named RealBook, different from existing and TouchFace-V interface, which can provide more direct viewing, natural and intuitive interactions with hand touch and gesture.

The animation exercises its influence all over the our lives, specially it has originated the new film industry by combining and applying with movies and CF. The current of time being active of animation industry brought about many changes to all the field of making films, planning and consumption. This paper is written for to inspect animation techniques that has developed to expand and break the limit of the animation's processing and expanding the part of expression. Specially by analyzing which is made by PIXAR, inquired how the 12 Disney animation skills were applied. As a result, the 12 Disney animation skills were combined to express one natual movement. Even though is 3D animation made by not Disney but PIXAR and made in 2004, it was applied and followed the 2D animation's the processing skill in 1987. Consequently, we could know even if the production, the way to produce and the time change, the exact same way of the 1987's producing skill has applied for now.

Landslide researches are divided to a method of interrelationship for various factors, method of predicting landslide possibility, and method of estimating landslide risk which are occurring landslides in the natural slope. Most of landslides occurred in natural slope are caused by a heavy rainfall in summer season. Weathered soil layer located in upper side of rock mass was occurred. As well as, they are announced to have an influence to geometry, geology, soil characteristics, and precipitation in the natural slope. In order to investigate and interpret the variety of landslides from field investigation to risk analysis, landslide analysis process due to geotechnical and geological opinions are systematically demanded. In this research, the study area is located in Macheon area, Gyeongsangnam-do and performed the landslide investigation. From the results of landslide investigation and analysis, optimized standard model based on natural landslide is proposed to high technical method of landslide investigation and interpretation.

The low and intermediate-level radioactive waste generated in Korea is disposed of at Wolsong Disposal Facility. For the safety of a disposal facility, it must be assessed by considering some abnormal scenarios including human intrusion as well as those by natural phenomena. The human intrusion scenario is a scenario that an incognizant man of the disposal facility will be occurred by the drilling. In this paper, the well usage scenario was classified into the human intrusion event as the probability of the well drilling is very low during the man's lifecycle and then was assessed by using conservative assumptions. This scenario was assessed using the dilution factor of contaminants released from a disposal facility and then it was introduced the applied methodology in this study. The assessed scenario using this methodology is satisfied the regulatory limits.

In reusable component retrieval systems with facet-based schemes, facet queries are generally used for representing the characteristics of components relevant to users. This paper proposes an expanded facet query equipped with an object-based thesaurus to precisely formulate user's intents. To evaluate the query, a component retrieval system is also designed and implemented. For exactly retrieving the components, user's query should include relevant facet values capable of fully specifying their characteristics. However, simply listing a series of facet values directly inputted by users, conventional queries fails to precisely represent user's intents. Our query, called expanded facet query, employs fuzzy boolean operators and object-based thesaurus; the former logically expresses the fuzzy connectives between facet queries and required components, whereas the latter helps users appropriately select the specific facet values into the query. A thesaurus query is provided to recommend the relevant facet values with their fuzzy degrees from the thesaurus as well. Furthermore, our retrieval system can automatically formulate queries with the recommended facet values, if necessary.

This paper discusses the design of a working system that visually recognizes hand gestures for the control of a window based user interface. We present a method for tracking the fingertip of the index finger using a single camera. Our method is based on CAMSHIFT algorithm and performs better than the CAMSHIFT algorithm in that it tracks well particular hand poses used in the system in complex backgrounds. We describe how the location of the fingertip is mapped to a location on the monitor, and how it Is both necessary and possible to smooth the path of the fingertip location using a physical model of a mouse pointer. Our method is able to track in real time, yet not absorb a major share of computational resources. The performance of our system shows a great promise that we will be able to use this methodology to control computers in near future.

The electronic float flow pattern system can predict a rate of flow of river by monitoring a location of float in remote with location measurement technology and a variety of communication technology. Now, to analyze the flow pattern of the natural streams, we use the manual floats in many forms. The measurement of a rate of flow using a manual float measures the distance and time of the manual float directly and uses it. It is inefficient for measurement method and exact a rate of flow of river. To overcome this problems, we designed and implemented the electronic float using CDMA, GPS, and RF module. Then, to get the location information and a rate of flow information, we designed and implemented the monitoring system for the electronic float flow pattern. The short life cycle of electronic float using the battery decreases the utility of the electronic float flow pattern system. Then, we design the power saving method to reduce the power of the electronic float in electronic float flow pattern system.
