  • In this paper a new "limited view frequency correlation algorithm" for diffraction topography is proposed. In this algorithm the problem of limited view sampling is solved by spectrum of spatial frequencies of refractive index. This algorithm is very important in a view of reduction of scanning time and improvement of considerably higher image quality object reconstruction.struction.

  • For accurate gain tuning of the lab-manufactured six-axis articulated robot RS2 with less noise, in this study, a program routine using dynamic signal analyzer, which is a realization of a controller design algorithm in the frequency domain, is programmed using LabVIEW$^{(R)}$. The contribution of this paper is the proposal of a simulation technique based on SolidWorks$^{(R)}$ and LabVIEW$^{(R)}$ for the gain tuning of a six-axis articulated robot. To realize the simulation, the LabVIEW$^{(R)}$ program used for experimental gain tuning is incorporated in to SolidWorks$^{(R)}$. A comparison shows that the results of simulation-based gain tuning and experimental gain tuning are almost the same within a 5% error bound. On the basis of the comparison, it can be suggested that the simulation-based technique for gain tuning can be applied instead of experimental gain tuning to a six-axis articulated robot by interlocking SolidWorks$^{(R)}$ and LabVIEW$^{(R)}$.

  • This article is to review the concepts of Confucian Utopia in Chosun Dynasty by looking into a sample of Daksil Village in Bongwha area. Here are some of the investigation. 1. The spatial composition entities of Daksil Village are both Confucian and Tao elements. 2. The whole views are made up by placing the Taoist View(gardens) into the Confucianist view(village and Seowon) and by placing the Confucianist view(summer house) into the Taoist view(Valley view of Seokcheonjeong). Two worlds are integrated into one by including each other. 3. According to the theory of geomancy(fang-shui), Daksil has the shape of ‘Geum-Gye-Po-Ran (Golden chicken embracing eggs)’, which is considered to be a land of fortune. Conclusively, Confucianists in Chosen Dynasty adopted fang-shui details when they built a residence, while they put much importance on Confucian and Tao elements. Moreover, it is found in the records that “It is a good place to start a village if there are mountains and water near the residence.” The fact that Daksil village is located at a day's distance from Seowon-Seokcheonjeongsa-Village-Jaesil-Grave proves that the residential village is set at an ideal place.

  • Driver's view has blind spot of automobile surroundings due to physical components of automobile architecture. Obstacles on blind spot are the cause of car destruction and car accidents. Cars which produced in recent have obstacle detection sensors and rear view cameras which provide information of obstacles on the blind sopt, and have also AVM(Around View Monitoring) which provides automobile surroundings for driver's safe driving. During a low-speed travel while parking or moving in a narrow street, a driver get help for safe driving by taking information of automobile surroundings using the above-mentioned devices. In this paper, we present a design and implementation of a 4-sided monitoring (4SM) system, which helps a driver see an integrated view of a vehicle's perimeter at a glance, using a car PC connected to four cameras installed on the front, rear, left, and right sides.

  • Large-scaled apartment housing complex at outskirts of downtown which has direct influence on urban view concentrated on improving the space outside the complex like spatial composition of individual plan design, but neglected the contribution of urban view. However, as people's orientation toward urban areas was changed to quality from quantity, concerns on urban view have been gradually increased and planning of apartment housing has been extended to complex with view contributing to urban people as a factor composing the city in resident centered spatial composition. This study is therefore to examine the characteristics of view components of 13 apartment housing complexes at Sangmu District in Gwangju Metropolitan City and their influences on evaluating view image.

  • This paper deals with power electronic converter education program using LabVIEW. LabVIEW is a graphic based programming language with easy debugging, which is suitable for education program that can be used to study and figure out the operation of power electronic converters. When LabVIEW is employed as a simulation program of the operation of power electronic converters, the resulting program has the advantage such that the effects of the change of control variables and circuit parameters on the various variables such as the output voltage and the inductor current etc can be directly displayed without any separate compiling procedure. This paper shows the design procedure and the characteristics of the power electronics education program implemented by LabVIEW focusing on DC-DC converter among power electronic converters.

  • The This study attempted to analyze what perception and attitude teachers have on corporal punishment. For these purpose, 458 writings about corporal punishment that 140 teachers loaded on web-site were collected and were analyzed using qualitative content analysis. : First, each writing was open-coded according to specific theme or meaning relating to corporal punishment using Nvivo program. Second, coded materials were classified as a high category when having similar theme or meaning. As a result of this process, 2 highest categories, 6 high categories and 24 subcategories were yielded. Teachers with positive view on corporal punishment tend to think that corporal punishment has some educational values or usefulness and their views were classified as very positive view, limited-permissive view, and inevitable view. They thought that corporal punishment were closely related to teachers' authority. Teachers have negative views on corporal punishment on the basis that corporal punishment causes side effects, is contrary to essentials of education, violates human rights etc. Negative views that teachers have on corporal punishment were classified as absolutely negative view and negative view focused on side effects. They thought that corporal punishment were not related to teachers' authority. Comments have been made on positive view on corporal punishment from the perspective of reflective analysis and implications of the results on theory and practice were discussed with comments on research limitations.

  • LabVIEW coding for video dehazing was developed. The dark channel prior proposed by K. He was applied to remove fog based on a single image, and K. B. Gibson's median dark channel prior was applied, and implemented in LabVIEW. In other words, we improved the image processing speed by converting the existing fog removal algorithm, dark channel prior, to the LabVIEW system. As a result, we have developed a real-time fog removal system that can be commercialized. Although the existing algorithm has been utilized, since the performance has been verified real - time, it will be highly applicable in academic and industrial fields. In addition, fog removal is performed not only in the entire image but also in the selected area of the partial region. As an application example, we have developed a system that acquires clear video from the long distance by connecting a laptop equipped with LabVIEW SW that was developed in this paper to a 100~300 times zoom telescope.

  • In this study, we propose an improved view-based navigation method for obstacle avoidance and evaluate the effectiveness of the method in real environments with real obstacles. The proposed method possesses the ability to estimate the position and rotation of a mobile robot, even if the mobile robot strays from a recording path for the purpose of avoiding obstacles. In order to achieve this, ego-motion estimation was incorporated into the existing view-based navigation system. The ego-motion is calculated from SURF points between a current view and a recorded view using a Kinect sensor. In conventional view-based navigation systems, it is difficult to generate alternate paths to avoid obstacles. The proposed method is anticipated to allow a mobile robot greater flexibility in path planning to avoid humans and objects expected in real environments. Based on experiments performed in an indoor environment using a mobile robot, we evaluated the measurement accuracy of the proposed method, and confirmed its feasibility for robot navigation in museums and shopping mall.
