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.

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.

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.

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.

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.

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.

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.

Over time, children’s outdoor activities and opportunities for children to play, have continually declined. Such problems have led to increased interest in providing better physical environments for children’s active free play in residential neighborhoods. Previous research studies have generally focused on specific places (i.e. playgrounds and schoolyards) or types of buildings (i.e. apartment complexes). The primary goal of this paper is to identify the characteristics of neighborhood environments that are associated with play behavior by analyzing the types of children’s play spaces and their routes. Based on a week’s travel log and GPS data from 25 students who are in grades 1-3 in elementary school, this empirical study of Buk-chon, Seoul, demonstrates that children have used for their recreational use both ‘formal play spaces’, spaces specifically designed for recreational activities, and ‘informal play spaces’, spaces not intentionally designed for recreational activities. The results of analyzing children’s play behaviors and space conditions indicate certain environmental characteristics. Formal spaces include the following: 1) quality parks that are easily accessible, 2) schoolyards and small parks that are spacious yet close to residential areas, and 3) play spaces that are well connected with residential streets. Informal spaces include the following: 1) commercial facilities, bus-stop and alleys surrounding schools, 2) alleys near residences, and 3) streets(and their networks) within neighborhoods. Even without formal spaces, alleys around homes and schools and neighborhood streets have become ‘play routes’ for children in Buk-chon. Further research is needed to compare other residential areas, as well as the different types of buildings that exist in such areas, and identify the challenges between creating outdoor play spaces and maintaining residential neighborhoods’ characteristics.

The purpose of study is the effectiveness of music program applied with Arts PROPEL by developing and carrying out it in music curriculum in secondary education in national level, in order to pursue music education appropriate to this era. A mixed method was chosen for this purpose, and quantitative and qualitative research analysis was comprehensively interpreted to draw conclusions as follows. First, Arts PROPEL consisting of various musical activities in the areas of singing, playing instrument, listening, and creating music for 3rd graders in middle school considering the curriculum in national level was developed through the processes of domain projects focusing on production, perception, and reflection. Second, it was verified that Arts PROPEL music program had significant differences between the experiment group and the control group for improving self-efficacy and music cognition ability. Third, as a result of the analysis of the participatory observing note, interview materials, and process-folio based on the evaluation criteria and rubric, the students improved their participation in music learning and increased their interest in music as they communicated among the members and planned how to study. Through this study, it was confirmed that there would be positive possibilities of Arts PROPEL in regular music curriculum in Korea, and that there were differences of developing talents of students depending on learning methods. It is expected that the study will be effective method for students musical development, and furthermore, it is hoped that long-term and practical studies will continue. 본 연구는 우리나라 중등학교 음악과 교육과정에서 아츠 프로펠을 활용한 음악과 프로그램을 개발 및 적용하여 이에 대한 효과성을 목적으로 둔다. 실제 음악교육현장에서 발생하는 문제들과 한계점을 해결하고자 한 실행연구로써 혼합연구방법으로 설계하여 개발 된 프로그램 적용 유무에 따라 통제반과 실험반으로 나누어 음악적 흥미도, 자기효능감, 음악인지능력의 사전·사후 검사하였으며, 양적연구 대상자의 동일 학생들을 면밀하게 참여관찰하고 16명의 학생들을 선정하여 심층면담 하였으며 학습 과정을 담은 프로세스-폴리오를 분석하였다. 양적데이터 분석 결과 자기효능감, 음악인지능력 향상에 실험반과 통제반의 유의한 차이가 검증되었다. 질적 연구 분석 결과 학생들은 모둠원 간 소통하며 학습 참여도가 향상되고 학습에 대한 자신감이 신장되어 음악적 자기효능감이 향상되는 것으로 나타났다. 학생들은 전문음악인처럼 인지적으로 사고하여 음악 과제를 해결하려는 학습 태도 변화가 나타났으며, 의존도가 높은 통제반에 비하여 실험반은 독립적으로 자유롭게 창작곡을 제작하였다. 본 연구를 통해 우리나라 정규수업의 음악과 교육과정에서 아츠 프로펠을 적용한 음악과 프로그램이 긍정적인 가능성이 있다는 것을 보았으며, 학습 수행의 접근 방법에 따른 학생들 능력 향상에 차이가 나는 것을 알 수 있었다. 본 연구가 학생들의 음악적 성장에 도움이 되길 희망하며, 더 나아가 장기적이고 지속적인 실행연구가 이루어지길 바란다.

The goal of this study was to analyze the relationship between the willingness to communicate (WTC) and academic achievement among Vietnamese undergraduate students. The present study used the 27-item scale developed by MacIntyre et al. (2001) to measure WTC in 21 undergraduate Vietnamese students. The items of the scale were developed to measure WTC in the four language skills of speaking, listening, comprehension, and writing, and in contexts in and out of the classroom, but this study was limited to the items concerned with the in classroom context. The results showed an average for overall WTC of 3.53. For the four skills, the highest average was 3.53 for speaking, followed by 3.61 for comprehension, 3.51 for writing, and 3.44 for reading. A significant positive correlation was found between overall WTC and the WTC in the four skills. In particular, a high correlation was found between comprehension and production skills. The correlation analysis between overall WTC and academic achievement, and between WTC in the four skills and academic achievement did not reveal any statistically meaningful results. We argues that the results are affected by the fact that many Vietnamese students decide to pursue working activities after arriving in Korea. The contribution of this study was our investigation of WTC and language skills sub-components in Vietnamese undergraduate learners.
