This study investigates key factors affecting the activity of defense technology transfer through the questionnaire survey in Korea. Defense R&D investment has played an important role in promoting the commercial technology development as well as the targeted defense sector through the spin-off mechanism as shown in many countries. Recognizing the importance of effective and efficient investment in defense technology development, the advanced countries in defense technology are trying to establish optimal technology transfer mechanism to maximize the effect of the invested R&D at the national level considering the idiosyncratic features of their own countries. Because the technology transfer mechanisms are very distinct from country to country, it is natural to question "what are the determinants of the effective and efficient technology transfer in Korea?" We tested 19 potential factors and identified 11 factors that are significantly important as the determinants of technology transfer. From the empirical findings, we discuss some policy implications to promote the technology transfer.

In this study, the microbial levels on mixed vegetable salads, fresh fruits, and frozen fruits distributed in Korea were comparatively analyzed by food group, region, and quarter. Samples were collected from big markets in large cities from 2018 to 2019 and used for microbiological analysis. The levels of aerobic bacteria for mixed vegetable salads, fresh fruits, and frozen fruits were 6.48, 5.07, and 3.78 log CFU/g, respectively. As a result of analyzing the quarterly contamination levels of aerobic bacteria, the first quarter contamination level was 5.12 log CFU/g while the second quarter showed 6.26 log CFU/g, the third quarter 5.73 log CFU/g, and the fourth quarter 4.42 log CFU/g. A higher number of aerobic bacteria was observed in the second and third quarters when the temperature was higher. There was no difference in the number of bacteria by region. The levels of the coliform group were 1.98 - 3.93 log CFU/g in all samples, and Escherichia coli was detected at 1.38 log CFU/g in 3 out of 27 mixed vegetable salads. Since the mixed vegetable salad and fresh fruit used in this study exceeded the standard (3 log CFU/g) for unheated foods and E. coli was detected in three fresh fruits, stricter hygiene management in the manufacturing stage of salads and fresh fruit is required.

Purpose: The purpose of this study was to investigate the clinical manifestations and 5-year natural course of recurrent bronchiolitis or reactive airways disease (RAD) in infants. Methods: We reviewed the medical records of infants with recurrent bronchiolitis from January 2007 to December 2007 at The Catholic University of Korea St. Mary's Hospital in Incheon, South Korea. Additionally, we telephoned their parents to confirm their present medical statuses. Results: Sixty-three subjects with recurrent bronchiolitis were identified. The mean age at admission was 8.1 months and the number of males was 44 (69.8%). Of the 63 infants with recurrent bronchiolitis, inhaled corticosteroids, bronchodilators, and antibiotics were given to 62 (98.4%), 53 (84.1%), and 40 (63.5%), respectively. Among the total 63 subjects, we were able to contact the parents of 45 children by telephone. None of these children had been hospitalized during the previous one year period due to respiratory infections or for other medical reasons. Of the 45 subjects we were able to contact, 38 (84.4%) had not experienced any further respiratory difficulties at all. Five (11.1%) had been diagnosed with allergic rhinitis while two (4.4%) were being managed for asthma. Conclusion: Most children who presented with recurrent episodes of bronchiolitis in infancy did not show any further respiratory difficulties after five years of age.

Laboratory class is an integral part of biomedical engineering education. Current biomedical engineering curriculum in Korea mostly includes mandatory laboratory classes. Most of the Korean biomedical laboratory classes focus on electrical engineering aspects, while molecular/biological engineering aspects are neglected. Many leading universities in U.S.A. offer a more balanced laboratory class where both electrical engineering aspects and molecular/biological engineering aspects are considered. As a part of an effort to enhance undergraduate biomedical engineering education, a new biomedical engineering laboratory class is proposed to offer a more balanced laboratory learning experience.

본 연구는 유동층 조립기로 조립시킨 보리 미숫가루 입자들의 인스탄트 성질에 영향을 주는 인자들을 조사하였다. 조립에 사용된 바인더는 맥아당, 포도당, 젤라틴의 수용액과 물 이었으며 조립입자의 인스탄트 효과는 입자의 습윤성, 침강성, 분산성 및 용해성을 측정하여 결정하였다. 바인더의 종류별로 조립된 시료의 인스탄트 성질의 개선에 대한 기여도는 낮은 바인더 수용액에서 5%젤라틴수용액>5%맥아당수용액>5%포도당수용액의 순으로 나타났으며 물은 가장 낮은 인스탄트효과를 보였다. 바인더 용액의 농도증가에 따른 조립입자의 인스탄트성질은 포도당, 맥아당과 같은 당류의 경우 증가되었으나 젤라틴의 경우에는 이와 반대경향을 나타내었다. 조립입자의 크기가 인스탄트성질에 미치는 영향은 현저하였으며 입자의 크기가 $0.1{\sim}0.3mm$일 때, 시료의 인스탄트효과가 가장 좋았다. 조립입자의 건조온도($60^{\circ}C,\;70^{\circ}C,\;80^{\circ}C$)는 입자의 인스탄트효과에 거의 영향을 미치지 않았다. 바인더용액을 사용하여 조립한 미숫가루입자의 흡습속도는 각각의 상대습도(42%, 67%, 92%)에서 5%젤라틴수용액>5%맥아당수용액>5%포도당수용액의 순으로 빠르게 나타났으며 이러한 결과는 바인더 종류가 인스탄트 성질에 미치는 효과와 동일한 순서로 일치함을 보여주었다. Influencing factors on the instant properties of agglomerated parched barley powder prepared by fluidized bed agglomerator were investigated. Instant effect was measured by the determination of wettability, sinkability, dispersibility and solubility of agglomerated particles. Instant effect of agglomerated particle was influenced by sorts of binding materials, concentration of aqueous binder solution and agglomerated particle diameter. The binding materials for agglomerated process were water and aqueous solution of glucose, maltose and gelatin. Instant effect of agglomerated particles increased as the concentration of aqueous sugar solution increased. However, the effect of aqueous solution of gelatin on instant effect was inversely proportional to the concentration. The size of agglomerated particle had an outstanding effect on instant properties and the diameter of agglomerated particle ranging from 0.1 mm - 0.3 mm showed the excellent instant effect.

Readily available high resolution brain MRI scans allow detailed visualization of the brain structures. Researchers have focused on developing methods to quantify shape differences specific to diseased scans. We have developed a novel method to quantify shape information for a specific population based on Multidimensional scaling(MDS). MDS is a well known tool in statistics and here we apply this classical tool to quantify shape change. Distance measures are required in MDS which are computed from pair-wise image registrations of the training set. Registration step establishes spatial correspondence among scans so that they can be compared in the same spatial framework. One benefit of our method is that it is quite robust to errors in registrations. Applying our method to 13 brain MRI showed clear separation between normal and diseased (Cushing's syndrome). Intentionally perturbing the image registration results did not significantly affect the separability of two clusters. We have developed a novel method to quantify shape based on MDS, which is robust to image mis-registration.

개선된 학부 의공학 소프트웨어 교육과정을 위한 새로운 과목의 제안

박현진,Park, Hyun-Jin 대한의용생체공학회 2011 의공학회지 Vol.32 No.4

Biomedical engineering is a discipline where engineering principles and techniques are applied to the medical field. Biomedical engineering lies between traditional engineering and medicine and is an inter-disciplinary field in its nature. Current Korean undergraduate biomedical engineering curriculum is a simple list of traditional engineering courses combined with basic medical/life science courses. There have been efforts to improve biomedical engineering education to reflect its inter-disciplinary nature. Enhanced software course for biomedical engineering is proposed as a part of effort to overhaul the undergraduate biomedical engineering curriculum. In this newly proposed course, students will learn MATLAB and LabVIEW, which are the most widely used software tools in biomedical engineering.

The purpose of the present study is to examine the differential effects of anxiety factors on the reading anxiety levels of Korean second language (L2) learners. As a follow-up study of Park and Kim (2017), the present study grouped 40 advanced Korean L2 learners in terms of their reading anxiety levels, as low, mid, and high. The five factors of reading anxiety were those arising from comprehension, foreign language, vocabulary, culture, and negative attitudes (Park & Kim, 2017). We observed whether each factor affected the learners` L2 reading anxiety differently. The analysis found a significant group difference for the three factors, which were anxiety over comprehension, foreign language, and vocabulary, but no group difference was found for the other two factors. Correlation analysis and multiple regression analysis also confirmed this result. We conclude that reading anxiety is a complex composite of factors, some of which affect reading anxiety more strongly than others, even when the learners show similar proficiency in the target language.

블렌디드 러닝을 활용한 방과후학교 피아노 프로그램 개발 및 효과

박현진(Park hyun jin) 한국음악교육공학회 2021 음악교육공학 Vol.- No.49

본 연구의 목적은 블렌디드 러닝을 활용한 방과후학교 피아노 프로그램을 개발하고 실제 현장에 실행연구하여 그 효과성을 검증하는데 목적을 둔다. 온·오프라인을 혼합한 효과적인 피아노 프로그램을 개발하고 학생들에게 나타나는 변화를 분석하기 위하여 혼합 연구로 설계하였다. 먼저 블렌디드 모형 5단계에 따라 피아노 학습의 구체적인 지도계획서 및 학습콘텐츠를 계획하고 한 학기의 프로그램을 개발하여 12주 동안 실제 교육현장에서 운영하였다. 학생들의 변화를 측정하기 위하여 음악적 흥미도의 사전·사후 테스트를 실시하여 양적 데이터를 분석하고, 관찰일지와 루브릭, 질문, 학습 영상촬영의 자료를 질적 분석하여 총체적인 의미를 찾고자 하였다. 음악적 흥미도의 양적데이터는 유의미한 향상이 검증되었고, 질적 분석 결과 점차 학습콘텐츠를 성실하게 시청하고 음악적 흥미와 관심이 높아지는 것이 관찰되었다. 음악적 흥미도가 높아짐에 따라 학습 자신감이 생기고 관심있는 제재곡을 스스로 선정하여 연주의 시청각 자료를 교수자에게 요구하는 모습을 보이는 자기주도학습의 가능성이 관찰되었다. 본 연구로 피아노 학습에서 블렌디드 러닝이 효과적인 학습 방안이 될 수 있음을 확인하였으며, 개발한 프로그램이 피아노 학습에서 유용한 학습 도구로 활용되길 희망한다. This study aims at developing an after-school piano program using blended learning and studying the practice in the actual site for its effectiveness. It started from the necessity to develop effective an after-school program for school education situation balancing in both online and offline schooling. A mixed method was designed to develop effective piano program applying to mix both online and offline and to analyze changes on students. Firstly, according to five steps of blended model, piano lesson was planned and specific teaching plans and learning contents were developed for a program during a semester, and it was applied to the actual educational field for 12 weeks. In order to measure students’ changes, pre- and post-tests on musical interest were conducted, the quantitative data on 21 students were analyzed, and qualitative data including observation logs, rubrics, and learning video were analyzed for finding the comprehensive meanings. Quantitative data on musical interests were verified with signifiant improvements, and for qualitative analysis results, the students watched the learning contents more sincerely, raising their musical interests and concerns. As musical interests were raising, students’ confidence of learning was made and there were possibilities of self-directed learning to choose a music with interests and to request teacher to offer the sources for playing. This study confirmed that blended learning in piano lesson could be a useful method, and it is expected that the developed program will be an educational tool for learning to play the piano.
