          비전 센서를 이용한 차선 감지 알고리듬 개발

          박용준,허건수,Park, Yong-Jun,Heo, Geon-Su 대한기계학회 2002 大韓機械學會論文集A Vol.26 No.8

          A lane sensing algorithm using vision sensors is developed based on lane geometry models. The parameters of the lane geometry models are estimated by a Kalman filter and utilized to reconstruct the lane geometry in the global coordinate. The inverse perspective mapping from image plane to global coordinate assumes earth to be flat, but roll and pitch motions of a vehicle are considered from the perspective of the lane sensing. The proposed algorithm shows robust lane sensing performance compared to the conventional algorithms.

          2009 개정 수학 교과용 도서의 인성 요소 분석 - 3, 4학년을 중심으로 -

          박용준,박만구 한국초등수학교육학회 2015 한국초등수학교육학회지 Vol.19 No.4

          본 연구는 2009 개정 3,4학년 수학 교과용 도서에서 인성 요소를 어떠한 방식으로 포함하고 있는지 분석하는 것을 목적으로 하였다. 이 연구에서는 교과서 및 교사용 지도서에 제시된 자료 중에서 인성 요소를 발견할 수 있는 부분을 먼저 찾고, 그것이 어떤 방식으로 수학적 내용과 연계되고 있는가를 분석하였다. 본 연구의 연구 결과는 다음과 같다. 첫째, 3,4학년 수학 교과서 대부분의 단원에서 인성 요소를 발견할 수 있었으나 특정 인성 요소에 편중되어 있었다. 둘째, 인성 요소를 연계하고 있는 방식으로 직접적인 인성적인 소재 활용이 가장 많았고, 수학적인 개념과 접목, 광의의 관점에서 접목, 그리고 문제해결 단계에서 접목하는 방법 순으로 빈도가 많았다. 셋째, 상대적으로 책임, 인내, 공정, 용기 등의 인성 요소가 취약하게 다루어졌다. 본 연구 결과 시사점으로는 편중되어 있는 인성의 요소를 가능한 고르게 반영하여 초등학교 수학 교과용 도서를 개발할 필요가 있다. 그리고 단순한 인성적인 소재 활용 외에도 수학적인 개념과 접목하거나 광의의 관점에서 접목하는 등의 수학적으로 보다 의미 있는 인성 요소 연계방안에 대한 후속적인 연구가 필요함을 제안하였다. The purpose of this study was to analysis how the elements of character are reflected in the 3rd and 4th grade elementary mathematics textbooks based on the 2009 revised curriculum. This study focused on the elements of character in the 3rd and 4th grade mathematics textbooks. The researchers analyzed the elements of character in the students’mathematics textbooks and teacher’s guide books. In particular, they analyzed how those elements of character are reflected in those books. Findings of this study are as follows. First of all, the elements of character were founded in the most of units on the 3rd and 4th grade mathematics textbooks, but they were biased to the specific elements of character. Second, the resources using related with character vary in the textbooks. As methods of character education, connections of elements of character with mathematical concepts, broader view of the world, or problem solving are appeared. From the results of the research, we suggest the followings. We need to set the teacher’s roles in character education. Mathematics textbooks should include various elements of character for effective character education. In addition to development of quality materials for character education in mathematics education, teacher education programs should include character education in mathematics education.

          Structural Analysis of Simulated Fission-Produced Noble Metal Alloys and Their Superconductivities

          박용준,이광용,이종규,허용득,김원호,Park, Yong Jun,Lee, Gwang Yong,Lee, Jong Gyu,Heo, Yong Deuk,Kim, Won Ho Korean Chemical Society 2000 Bulletin of the Korean Chemical Society Vol.21 No.12

          Ternary (Mo-Ru-Pd) and binary (Mo-Ru, Mo-Pd) alloys have been prepared using an Ar arc melting furnace. Mo and the noble metals, Ru and Pd, are the constituents of metallic insoluble residues, which were found in the early days of post-irradiation studies on uranium oxide fuels. In the present study, the structure of the alloys was evaluated using a powder X-ray diffractometer. Unit cell parameters were determined by least squares refinements of powder X-ray diffraction data. Scanning electron microscopic analyses of the surface of the alloys indicated that surface morphology was dependent on the crystallographic structure as well as its composition. Measurements of the magnetic susceptibility of the alloys showed evidence of superconducting transition from 3 to 9.2 K. Among the ternary and binary alloys, the ${\sigma}-phase$ showed the highest superconducting transition temperature,~9.2 K.

          Re-Weaving Freobel’s Gifts in a Post Human Era

          박용준,양유진 제주대학교 교육과학연구소 2018 교육과학연구 Vol.20 No.1

          We designed and produced Froebelian Activity, a combination of “Froebelian Box” and “Froebelian Design Software” intended for use in pre-k classrooms. The main concept of Froebelian Activity is to use Froebel’s Gifts and pedagogy to help preschoolers understand the concepts of classification, including parts to whole and whole to parts. We tested the initial products with nine preschoolers from three to five years old in a classroom setting, revised and then re-produced them using the testing method such as “usability group play testing.” Most preschoolers could manipulate the activities and computer programs very well following the teacher’s constructive guidance. They were especially interested in manipulating the practical cubes from the Froebelian Box and the virtual cubes in the Froebelian Design Software. However, many of them did not enjoy watching movie clips or simulations showing the concepts “whole to parts and parts to whole.” This implies that young children are very active learners who are willing to explore new materials in hand. Learning-material designers could test initial products with a combination of hands-on manipulatives and computer games with a teacher’s clear guidance. In addition, children’s computer game designers and educators can still adopt good ideas from the past like Froebel’s and re-create them after understanding the original educational purpose.

          우라닐 가수분해물의 용해도 연구

          박용준,표형렬,김원호,전관식,Park, Yong-Joon,Pyo, Hyung-Ryul,Kim, Won-Ho,Chun, Kwan-Sik 대한화학회 1996 대한화학회지 Vol.40 No.9

          서로 다른 pH 조건에서 생성한 우라닐 가수분해물의 용해도에 미치는 지하수 성분의 영향을 측정하였다. 우라닐 가수분해 침전물 pH 6.4 및 9.7에서 제조하였다. 편마암 층에서 채취한 지하수로부터 무기 및 유기콜로이드를 제거한 분리지하수, 채취지하수의 분석성분과 동일한 조성을 가지는 합성지하수, 그리고 0.1 M NaCl 수용액에서의 용해도에 미치는 pH의 영향을 측정하였다. 또한 채취지하수에서 상대적으로 다량 존재하는 음이온 및 양이온의 영향을 측정하였다. 지하수에서의 우라닐 가수분해 침전물의 용해도는 0.1 M NaCl 용액에서보다 약 100배 정도 큰 것으로 나타났다. X-선 회절분석 결과는 높은 pH에서 제조한 우라닐 가수분해 침전물이 낮은 pH에서 제조한 것보다 낮은 결정화도와 높은 용해도를 보였다. The effects of chemical species in groundwater on the solubility of the uranyl hydrolysis precipitates formed at pH 6.4 and 9.7 were investigated. Based on the chemical composition of the groundwater, the synthetic groundwater was prepared. The colloid-free (separated) groundwater was also prepared by removal of both organic and inorganic colloids from the sampled groundwater. Solubilities of precipitates formed in the hydrolysis of uranyl ion in groundwater, separated groundwater, synthetic groundwater and 0.1 M NaCl solution were measured over neutral to alkaline pH range, and especially, the effect of the anions and cations found in groundwater on the solubility was investigated. Solubility in groundwater was approximately two orders of magnitude greater than that in 0.1 M NaCl solution. Soubililties of uranyl hydrolysis precipitates formed at pH 9.7 and 6.4 were compared in groundwater and synthetic groundwater. Solubilities of the precipitates formed at different pH were found to be in the same order of magnitude in groundwater and synthetic groundwater, however the uranyl hydolysis precipitates formed at higher pH values showed a tendency of higher solubility.
