양희정,이유경,주천기,문정일,목지원,박명희 대한안과학회 2015 Korean Journal of Ophthalmology Vol.29 No.4

Purpose: To describe clinical findings in a Korean family with Axenfeld-Rieger syndrome. Methods: A retrospective review of clinical data about patients with diagnosed Axenfeld-Rieger syndrome. Five affected members of the family underwent a complete ophthalmologic examination. We screened the forkhead box C1 gene and the pituitary homeobox 2 gene in patients. Peripheral blood leukocytes and buccal mucosal epithelial cells were obtained from seven members of a family with Axenfeld-Rieger syndrome. DNA was extracted and amplified by polymerase chain reaction, followed by direct sequencing. Results: The affected members showed iris hypoplasia, iridocorneal adhesions, posterior embryotoxon, and advanced glaucoma in three generation. None had systemic anomalies. Two mutations including c.1362_1364insCGG and c.1142_1144insGGC were identified in forkhead box C1 in four affected family members. Conclusions: This study may help to understand clinical findings and prognosis for patients with Axenfeld-Rieger syndrome.

The study aimed to determine the effect of gait training using partial weight-bearing equipment on static balance, dynamic balance, step length and dynamic gait index in patients with chronic stroke. In this study, 16 patients with chronic stroke participated. This is a pre-post comparison study conducted on 16 chronic stroke patients as one group pre test-post test design. The experiment involved gait training using a partial weight-bearing equipment, with a duration of 20 minutes, 3 times a week, for a total of 18 sessions over 6 weeks. static balance (STB), timed up and go (TUG), step length, and dynamic gait index (DGI) were evaluated before and after the intervention. Paired t test coefficients were used to evaluate the significance level between static balance, dynamic balance and gait function in patients with stroke. STB showed a significant correlation with STB (p<.05), TUG (p<.05), step length (p<.05) and DGI (p<.05). The initial trunk control ability and gait ability at discharge in patients with stroke were correlated. The study results showed significant improvements in STB, TUG, step length and DGI after the intervention compared to before. Based on these research findings, it is believed that gait training using the partial weight-bearing equipment a positive effect on static balance, dynamic balance, and gait function in chronic stroke patients.

아한한아 의료통역 교육의 실효성 및 발전 방안 연구

양희정 명지대학교(서울캠퍼스) 중동문제연구소 2022 중동문제연구 Vol.21 No.2

코로나 팬데믹이 시작되기 전 10여 년간 UAE를 필두로 한국을 방문한 중동 환자의 수가 급속도로 증가하면서 의료통역사에 대한 수요도 급증했다. 2009년부터 정부기관을 시작으로 대학(원)에서 의료통역 교육과정과 강의를 운영했다. 의료통역 교육 실효성에 대한 연구가 부족하여, 본 연구는 교육과정을 분석하고 만족도와 보완할 점을 설문조사해 의료통역 교육의 발전 방안을 모색하는 것이 목적이다. 구글 설문지를 통해 의료통역사 및 코디네이터, 의료진, 환자 및 보호자 3그룹을 대상으로 의료통역 교육에 대한 설문조사를 진행했으며, 엄중한 상황 속에서 큰 어려움이 있었지만 유의미한 결과를 도출할 수 있었다. 교육 내용이 크게 재편되면서 보완된 부분과 더 보완이 필요한 부분을 발견할 수 있었고, 그룹 별로 느끼는 교육에 필요한 부분과 교육 이수, 검정시험 합격 등의 통역사 검증의 중요성을 확인할 수 있었다.

청말 일본으로의 유학생 파견과 일본어

양희정 중국근현대사학회 2012 중국근현대사연구 Vol.54 No.-

1894年の日清戦争で日本に敗北したことを皮切りに、中国は近代化の持つ力を思い知り、日本から「近代」を学ぼうとする。その際必然的に求められる日本語の人材を養成するため、日本語教育が始まる。1896年、近代中国初の日本留学生が派遣され、中国内でも数々の日本語学校が登場する。しかし列強の侵略や反清運動など、不安定な状況が続く中で国内での教育は成長できず、日本留学だけが成果をもたらすことになる。ところで、清末の日本留学は近代の学問を身につけることに重点が置かれていたため、中国人留日学生に対しては主に速成教育が行われていた。留学生には儒教教育の経験しかなかったため、数学や物理、化学など基礎学問の知識がなく、目指している高等な技術などを得るためには長年の学習が必要であった。しかし近代化を進めようとする清朝からみると、良質の教育とともに短期間で学業を終え政策の実行を担ってくれる人材を養成することも重要な課題であった。そこで生まれたのが速成科である。そしてその速成科では教授期限を短縮させるために主に言語修得の期間を削る方法が取り入られていた。 「漢字」という同じ文字を用いる利点に加え、言語習得から離された留学の目的、手段としての速成科の流行、通訳を通じた授業や中国人だけの宿舎生活等々、当時の状況を考えると留学生に日本語能力が必ず求められていたのか疑問が生じる。しかし留学生たちが在籍していた中国人向けの教育機関ではしっかりと日本語教育の場を設けていた。当時の学科は普通科と専門科に分けられる。普通科は日本の高等専門学校へ入学するために普通学と日本語を教えることを目的に設けられたものである。したがって普通科での教育経験はより高等な教育を受けるための基盤となっていたのである。そしてその普通科の教育の中では全体の半分ほどの時数が日本語教育に使われていた。特に1年目に日本語の授業を集中させることで日本語が普通学より先に学ばれるようにしていた。専門科は文字通り普通科より専門的な内容を教授する学科であった。留学生に最も人気があったのは師範、警務、法政の学科で、速成教育は多くの場合これら専門科に用いられていた。しかしすべての専門科が日本語教育を行っていなかった訳ではない。学校によって修業年限3年以上の速成ではない専門科を設けていたり、また速成科でも日本語が教授されていた例もある。専門科教育は速成で教授するが、その予備教育として普通科過程を必ず卒業するように定められていた学校もあった。すなわち専門科の中でも一部は日本語の教育が行われていたのである。また清末に制作された日本語学習書からも留日学生の日本語学習を確認できる。戦前の日本において刊行された日本語学習書の多くは中国人の日本留学がブームをなしていた同時期に刊行されたものである。このことは当時の中国人留学生による学習書の需要が相当なものであったことを意味する。そしてその学習書の多くが留学生教育の経験から書かれたものである。つまりこの時期に刊行された学習書から中国人留日学生に行われた日本語教育の方法や内容を窺えるのである。それらの学習書は語彙、構文、文法、読解の内容から日本語を説明していた。初めは中国語の語彙にあ...

Selective Deposition of Co Thin Films for TFT Gate Electrode by Non-OpticMethod; Micro-Contact Printing and MOCVD

양희정,희정 양,신현정 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.47 No.3

Selective deposition of Co thin films for a TFT gate electrode is carried out by growth with a combination of micro-contact printing and metal organic chemical vapor deposition (MOCVD) at low temperature below 100 C. An octadecyltrichlorosilane (OTS) layer of long chain defined with polydimethylsiloxane (PDMS) stamps was pre-patterned onglass. The patterned OTS area has hydrophobic characteristics while surface on glass has hydrophobic characteristics. The MOCVD Co selective deposition is focused on the difference of incubation time for the react on between functional group and Co precursor. We optimize selective conditions of Co deposition for a gate electrode to reduce the photo mask level. Root mean square (rms) of Co films deposited is 2 nm, enough to use as gate electrode possessing a smooth surface. OTS pattern is decomposed by UV treatment in the range of 280 to 350 nm and then trilayer is continuously created on the sample, which is selectively organized asCo gate electrode on glass. We fabricate a thin film transistor (TFT) of inverse staggered type by using this sample. Reflectance is used to evaluate incubation time for Co deposition and AFM isemployed to confirm the selectivity of Co thin film. The subthreshold slope and on/off current ratio are 0.88 V/decade and 6 × 106, respectively. The electron field-effect mobility at saturation is 0.35 cm2/Vs for Vd = 9 V.

As the use of computers and internet service has increased fast, various web-based coursewares for the educational purpose have been devoloped. However, the development of web-based coursewares for old-aged adults is far from satisfactory. Since most existing web-based coursewares are designed for the youth, they are not proper for old aged people to use confidently. In this paper, we analyse psychological, social and physical characteristics of old aged adults and propose the starategy for designing web based coursewares for them. Then, We apply the design strategy to develop the web-based courseware in Excel subject and analyse the effect of the design strategy by means of questioning and answring. 컴퓨터와 인터넷 사용의 급속한 확산에 따라 다양한 교육용 웹기반 코스웨어의 개발이 이루어지고 있다. 그러나, 장년 성인학습자를 위한 웹기반 코스웨어의 개발은 아직 미흡한 편이다. 기존의 웹기반 코스웨어는 주로 젊은 층을 대상으로 설계되어 있어 장년 성인들이 사용하기에 적당하지 않다. 본 논문에서는 장년의 성인들의 심리적, 사회적, 신체적 특성을 분석하고 이들을 위한 웹기반 코스웨어의 설계 방안을 제시한다. 그리고 제안한 설계 방안을 엑셀과목의 웹기반 코스웨어에 적용하고 그 결과를 설문조사를 통해 분석하였다.

To elucidate the hemolytic toxicities of Korean basidiomycetes, the cold-water extracts of 46 wild mushrooms were tested for hemolytic activity on mouse erythrocytes. Twelve species including Amanita esculenta, A. griseofarinosa, A. longistriata, A. melleicepe, A. phalloides, A. rubescence, A. spissacea, A. vaginata, Hebeloma crustuliniforme, Lepiota cygnea, Macrolepiota procera, and Oudemansiella platyphylla showed strong hemolytic activities. Of these, A. griseofarinosa and H. crustuliniforme showed no decrease in their hemolytic activity even after five minutes' boiling.
