Single crystal silicon (SCS) is used in a variety of microsensor applications in which stresses and other mechanical effects may dominate device performance. The authers model temperature dependent mechnical properties during focused io beam(FIB) cutting and Pt deposition processes. In microaccelero-meter manufacturing process, this paper intend to find thermal displacement change of the temperature by tunnel gap, additional beam part and pt deposition. The thermal analysis intend to use ANSYS V5.5.3.

Expression of color in national animation often delivered vaguely. This study will make up for vaguely meaning in terms of expression in color. And this study is intend to look the strategy and error of color in regional animation. This study is intend to arrange the situation of synesthesia effect of color which is applied as a keyword 'light' of Gwang-ju's image. Moreover, There is a bit difficulty in using synesthesia of color, but the use possibility is full of suggestions. Therefore, For regional animation, this study intend that in order to establish a new regional specialized animation, appropriateness of synesthesia effect of color in based animation is inspected and then the potential is emphasized.

Variable contents are extracted and used to improve the correctness of the retrieval in the content-based in age retrieval. This way use the physical feature for the retrieval. In this way of retrieval, the user has to know the basic physical features and spatial relationship of target images that he wants to retrieve. There are some restriction to reflect the user's intend. We need the retrieval system that reflect the user's intend. In this paper, we propose an emotion-based retrieval system. It is different from past emotion based image retrieval in point of view that it uses relevance feedback to estimate the users intend and it is easily combined with past content-based image retrieval system. The features and similarity measures are adopted from MPEG-7 color descriptors which are proper retrieval of large multimedia databases. We use wallpaper images for the experiment. The result shows that the system get successful result.

Currently, as Korea enters into a fast aging society, the problem of dementia population is increasing. In this paper, we intend to contribute to the improvement of welfare for the elderly by developing virtual reality technology and related interface technology to effectively perform hand movements known as effective methods for preventing and treating dementia. As the content of the research and development of this paper, it is designed to be easy for the elderly to use and stimulate brain function by applying VR technology using sensors, and to activate mental and physical activities for the elderly who are marginalized in terms of cultural welfare. We intend to develop by classifying the types of games and contents that can induce them. As a result of this thesis, we developed contents using virtual reality to improve cognitive abilities for elderly people with poor cognitive ability to activate the brains of users' cognition, memory, and attention to prevent and treat dementia I want to contribute.

In the design of AGVS (Automated Guided Vehicle Systems), one of the important problem is to determine the number of AGVs required to provide a given level of transport service. At present, there are two kind of methods to determine the number of AGVs, the one is to use the mathematical model, the other is to use the simulation technique. Among these, simulation based technique is more reliable than analytical method. In this sense, this paper intend to determine the optimal number of AGVs using personal computer simulation by SIMAN Ver.3.5.

Through this research, I intend to examine the possibility of utilizing the plaza in front of a station as a citizen plaza within the city, which citizen can use actively. Until now, the plaza in front of a station is utilized as a traffic square. As part of this examination, I'll consider a plaza generally and analyse the present condition of the plaza in front of a station as well as physical environment. Then I will grasp the present condition and problems. Through this, 1 intend to extract basic materials enough to find the possibility of the plaza in front of a station as a citizen resting place.

This study aims to investigate how secondary mathematics teachers understand and intend to use textbooks for their mathematics instruction. For this purpose, we developed a set of survey items in order to unpack what the teachers understand the mathematical tasks suggested in the textbooks in terms of the levels of cognitive demand and how they intended to use the tasks in the textbooks for their teaching. Twenty-five teachers participated in the survey. The data from the survey were analyzed. The findings from the data analysis suggested as follows: a) the teachers seemed to closely follow textbooks without attempting to modify the tasks, even when the teachers consider it is necessary to modify textbook tasks to high-level tasks, b) the teachers seemed to be unstable in regards that they admitted themselves very competent for modifying tasks for developing students' mathematical thinking but, at the same time, they were uncomfortable with transforming tasks into cognitively demanding tasks that promote students' mathematical understanding, and c) the teachers appeared to consider textbooks as significant criteria in conducting tests including midterm and final exam. In conclusion, the teachers seemed to intend to follow closely the contents and sequence of mathematics textbooks in their mathematics classrooms.

A lab-use home made control valve was made of easily obtainable materials and its performance was examined through a fluid flow experiment. By modifying the hole of a commercial valve a linearly adjustable valve for the flow control is made. The detail of valve assembling and modification is explained for the researchers who intend to employ a similar control valve.

When we drive a vehicle in an IoT environment, there is a problem in that information of car users is collected without permission. The security measures used in the existing wired network environment cannot solve the security problem of cars running in the Internet of Things environment. Information should only be shared with entities that have been given permission to use it. In this paper, we intend to propose a method to prevent the illegal use of vehicle information. The method we propose is to use attribute-based encryption and dynamic threshold encryption. Real-time processing technology and cooperative technology are required to implement our proposed method. That's why we use fog computing's proxy servers to build smart gateways in cars. Proxy servers can collect information in real time and then process large amounts of computation. The performance of our proposed algorithm and system was verified by simulating it using NS2.

Virtual reality has been new useful technology which have been brought our from the development of computer and computer based multimedia. Computer simulation application among the technologies of the virtual reality has spreaded into air service, motor vehicle, medical science, sports, education, even fashion industry. This study aims to look into application of computer simulation on hairdressing industry and researches 2-dimensional hairstyle computer simulation system which is started to common use nowadays and the 3-dimensional system which is under the development and furthermore investigates the usefulness of the 2D hairstyle simulation by questionnaire from its users. Statistical analysis show that 64.6% of examiners are satisfied at the results of 2D hairstyle simulation, 50.6% of them intend to recommend it to others and 63.3% of them intend to speak highly of it.
