독해만을 필요로 하는 제로(0) 초급자에 대한 지도 -서울대학교 언어교육원에서의 "독해 첫걸음" 실천보고로부터-

蹈川右樹 ( Inagawa Yuki ) 한국일어교육학회 2010 일본어교육연구 Vol.0 No.19

한국에서의 일본어교육은 1980년대 이전의 문법번역법 시대부터 몇 가지의 변화를 통해, 현재는 의사소통 교육법이 주류가 되고 있다. 하지만 동시에 학습자 측의 수요도 다양화하고 있어, 그 중에는 종합적인 의사소통 능력의 획득을 목적으로 하지 않은 학습자도 존재한다. 본고에서는 그 중에서도 특히 서울대학교 언어교육원에서 저자가 실시하고 있는 "독해 첫걸음"이라는 독해만에 특화된 수업의 실천보고를한다. 그 결과 한국어를 모어로 하는 학습자라면 일본어문법을 몰라도 단기간에 상당부분 독해가 가능해지고, 학습자도 그 결과에 만족하고 있는 것이 밝혀졌다. 하지만 이 교육과정은 신문기사나 논문 등 비교적 교과서 문법의 틀에서 벗어나지 않은 문장의 독해에는 힘을 발휘하지만, 구어적 문장에는 충분히 대응 하지 못하는 것이 동시에 밝혀졌다. 실천 사례의 양적 축적 중에서 어떤 문장을 읽을 수 없는지, 또 그런 문장을 읽을 수 있게 되기 위해서는 어떤 지도가 추가되어야 하는지 탐구하는 것이 향후의 과제이다. 韓國における日本語敎育は1980年代以前の文法飜譯法の時代から、いくつかの變遷を遂げ、現在においては、コミュニカティブアプロ一チが主流之なっている。しかし、學習者側のニ一ズも多樣化しており、必ずしも綜合的なコミュニケ一ション能力の獲得を學習目的之しない學習者も確かに存在する。本稿ではその中でも特に、ソウ兒大學言語敎育院において行っている「독해 첫걸음(はじめての讀解)」之いう讀解のみに特化した授業の實踐報告を行う。その結果、韓國語を母語之する學習者であれば、日本語文法を知らなくても短期間に相當程度の讀解が可能になり、學習者もその結果に滿足していた。しかし、このカリキュラムは新聞記事や論文など、比較的敎科書文法の樣からはみ出ない文語的文章の讀解には力を發揮しても、口語的文章には十分對應できないこ之が同時に明らかになった。更なる實踐の積み重ねの中からどのような文章が讀めないのか、また、それらの文章を讀めるようにするためには、どのような指導が追加されるべきなのかの探求が今後の課題である。

한국에서의 일본어 방언교육-국제교류기금 “간사이의 언어와 문화”의 실천보고-

이나가와유키 ( Yuki Inagawa ) 한국일어교육학회 2014 일본어교육연구 Vol.0 No.30

본연구는 필자가 2013년 6월부터 국제교류기금일본문화센터에서 담당하고 있는 문화강좌 “간사이의 언어와 문화”에 대한 실천보고를 통해, “한국에서 방언을 가르치는 일”이 가지는 의의에 대해 고찰하는 것을 목적으로 한 것이다. 기존의 일본어교육에서는 도쿄방언을 중심으로 한 공통어교육이 주로 실시되고, 일본어 방언에 대해서는 언급되지 않는 것이 보통이었다. 하지만 근래 일본국내에서 방언의 재평가, 지역사회에 깊이 관여해서 생활하는 학습자의 증가 등의 영향으로 외국어로써의 방언교육이 부분적으로 시작되고 있다. 다만 그러한 방언교육은 어디까지나 해당 지역에 거주하는 학습자가 그 지역에 적응하기 위해 행해지고 있는 것이다. 한편 본연구는 그것과는 전혀 다른 차원의 움직임인 “한국국내의 간사이 방언에 대한 관심”에 부응하게끔 실시된 것이다. 생활 속에서 간사이 방언을 전혀 필요로 하지 않는 한국인학습자가 어떤 학습동기를 가지고 간사이 방언을 배우려 하는가, 무엇보다 한국인에게 간사이 방언을 배우는 것은 과연 어떤 의의가 있는가, 그러한 의문을 개강 전, 종강 전에 실시한 두 설문조사 결과를 바탕으로 밝히려 했다. 그 결과 당강좌를 수강한 학습자의 대부분이 매스미디어 영향을 받고 있었으며, 그것은 근년 일본에서도 언급되고 있는 “간사이에 대한 동경” 현상이 한국의 일본어학습자 사이에서도 확산되고 있음을 시사하는 것이다. 사전 설문조사에서 “간사이 방언 청해능력 향상”에 대한 기대가 많았 던 것도 그 문맥과 무관하지 않을 것이다. 종강시 설문조사 결과를 보면 “간사이를 실제로 방문하고 싶어졌다”는 대답이 압도적으로 많았고, 방언학습이 해당지역에 대한 적극적 관심형성이 되는 것도 밝혀졌다. 이상의 결과에서 한국에서의 간사이 방언 교육은 일정한 수요가 있으며, 게다가 간사이지역을 어필하기 위해서도 충분히 의의가 있다는 것을 알 수 있었다. 하지만 사전 설문조사에서 학습자가 기대한 수업내용과 수강 후 소감 간에 갭이 존재함을 나타내는 데이터도 있는 등 학습자의 요구를 정확히 파악하고 부응할 수 있는 학습과정을 만들어 나가는 것이 앞으로의 과제일 것이다. 本硏究は筆者が2013年6月から國際交流基金日本文化センタ一にて단當している文化講座「關西のことばと文化」についての實踐報告を通して、「韓國で方言を敎えること」が持つ意味を考察することを目的としている。旣存の日本語敎育では東京方言を中心とした共通語敎育が主に實施され、日本語の方言については言及されないのが普通であった。しかし、近年日本國內において、方言の再評價、地域社會に深く關わって生活する學習者の增加などの影響により、外國語としての方言敎育が部分的に始まっている。ただ、そのような方言敎育はあくまでも地域に居住する學習者がその地域に適應するため行われている。一方、本論文ではそれとは全く違う次元の動きである「韓國國內の關西方言に對する關心」に應えるべく行われたものである。生活の中で關西方言を全く必要としない韓國人學習者がどのような學習動機を持って關西方言を學ぼうとするのか、また何より韓國人にとって關西方言を學ぶ行爲は果たしてどのような意義があるのか、そのような疑問に對し、開講前·開講後に實施した二つのアンケ一ト調査の結果をもとに明らかにする。その結果、當講座を受講する學習者のほとんどがメディアの影響を受けており、それは近年日本でも言及されている「關西に對する憧れ」現象が韓國の日本語學習者の間でも廣まっていることを示唆するものである。事前アンケ一トにおいて、「關西方言の聽きとり能力の向上」に對する期待が高かったのも、同樣の文脈から分析できる。終講時アンケ一トの結果を見ると、「實際に關西を訪問したくなった」という回答が壓倒的に多く、方言學習が該當地域に對する積極的な關心形成につながることがわかった。以上の結果から、韓國における關西方言は一定のニ一ズが存在し、さらに關西地域のアピ一ルといった側面からも、十分な意義があると言える。しかし、事前のアンケ一トで學習者が期待した授業內容と、受講後の感想の間にギャップがあることを示すデ一タもあるなど、學習者のニ一ズを正確に把握して應えられるカリキュラム作りが今後の課題であると思う。

A mixture of Salacia oblonga extract and IP-PA1 reduces fasting plasma glucose (FPG) and low-density lipoprotein (LDL) cholesterol levels

At present, lifestyle-related diseases are one of the most critical health issues worldwide. It has been reported that lipopolysaccharide derived from a Gram-negative bacteria (IP-PA1) symbiotic with wheat exhibited several advantageous biological effects, such as the reduction of plasma glucose levels in NOD mice and low-density lipoprotein (LDL) levels in WHHL rabbits. In this study, the beneficial effects on plasma glucose and lipids of a tea (SI tea) consisting of IP-PA1 and Salacia (which contains an inhibitor of ${\alpha}$-glucosidase) were investigated in the KK-Ay/TaJcl type 2 diabetic model mice and in human subjects with premetabolic syndrome in a double-blind, randomized study. S1 tea significantly decreased plasma glucose levels in KK-Ay/TaJcl mice. A clinical trial of SI tea was performed with 41 subjects between the ages of 40 and 69, who belonged either to a high plasma glucose group (HG: FPG 100-125 mg/dl) or to a hyperlipidemia group (HL: TG ${\geq}$ 150 mg/dl, or LDL ${\geq}$ 120 mg/dl, or HDL <40 mg/dl). These subjects ingested either Salacia without IP-PA1 (the control) or SI tea. Blood samples were collected at 0, 30, and 60 days after initiating SI tea treatment, and were measured for FPG, HbA1c, TG, LDL, and HDL. These results showed that SI tea reduced FPG and HbA1c more rapidly than the control in the HL group, and also significantly improved LDL and HDL levels in the HG group. Thus, SI tea may be helpful in preventing lifestyle-related diseases.

Background: Although the utility of flaps for the treatment of sternal wound infections following median sternotomy has been reported for 30 years, there have been few reports on the risk factors for complications after reconstruction. The objective of this investigation was to identify factors related to complications after the reconstruction of sternal wound infections. Methods: A retrospective analysis of 74 patients with reconstructive surgery after sternal wound infection over a 5-year period was performed. Clinical data including age, sex, body mass index (BMI), comorbidities, bacterial culture, previous cardiac surgery, wound depth, mortality rate, type of reconstructive procedure, and complication rate were collected. Results: The patients’ BMI ranged from 15.2 to 33.6 kg/m2 (mean, 23.1±3.74 kg/m2). Wound closure complications after reconstructive surgery were observed in 36.5% of the cases. The mortality rate was 2.7%. Diabetes mellitus significantly affected the rate of wound closure complications (P=0.041). A significant difference in the number of complications was seen between Staphylococcus aureus (S. aureus) and coagulase-negative Staphylococci (P=0.011). There was a correlation between harvesting of the internal thoracic artery and postoperative complications (P=0.048). The complication rates of the pectoralis major flap, rectus abdominis flap, omentum flap, a combination of pectoralis major flap and rectus abdominis flap, and direct closure were 23.3%, 33.3%, 100%, 37.5%, and 35.7%, respectively. Conclusions: Diabetes mellitus, S. aureus, harvesting of the internal thoracic artery, and omentum flap were significant factors for complications after reconstruction. The omentum flap volume may be related to the complications associated with the omentum flap transfer in the present study.
