We have clinico-statically analysed the 235 cases of esophageal foreign body during the period the past 12 years from March InS to December 1996 at the Department of Otolaryngology-Head and Neck Surgery, Korea University College of Medicine, Guro Hospital. The results were as follow : 1) Coin was the most frequent foreign body in the esophagus(172 cases : 73.2%). Bone was the next frequent foreign body (21 cases 8.8%). 2) In sex distribution, 124 cases(52.8%) of patients were the female and 111 cases(47.2%) were the male, so the sex ratio was 1:1.12. 3) In the age distribution, 134 cases(56.9%) were under 5 years of age, coin was the most frequent materials in this age group(111 cases 47.2%). 4) The most common symptom was vomiting(136 cases : 57.9%). The next common symptom was dysphagia and odynophagia was 41 cases(17.4%) 5) The most prevalent site of lodgement was the first narrowing(181 cases : 77.0%), the third narrowing(31 cases : 13.2%) and the second narrowing of esophagus(23 cases 9.8%) in order. 6) In duration of lodgement, 207 cases(88.1%) were lodged for one day. 7) The foreign bodies of esophagus were removed successfully by esophagoscopic procedure under local or general anesthesia. There were 3 cases of complication, one case of esophageal bleeding and two cases of esophageal rupture.

Aspiration of foreign bodies into the airway is a common problem in spite of efforts to educate the public, and it can be sometimes fatal accidents. We clinically analyzed 101 cases of airway foreign bodies treated in the Department of Otolaryngology-Head and Neck Surgery, Korea University College of Medicine for the past 10 years comparing data with the previous articles. There was male predominance in the occurrence rate, being 72% in the male patients. The peak age was 1 to 3 years of age, and 84.2% was below age of 10. The most common symptom after foreign body aspiration was intractable cough, and obstructive emphysema was most commonly found on the initial chest X-rays. Foreign bodies were mainly located at the right main bronchus and left main bronchus was the next. Peanuts were the most common airway foreign bodies. Ventilating bronchoscopy was performed in the 99 cases and foreign bodies were successfully removed in most cases. There was 2 deaths(2%) resulted from hypoxia after bronchoscopy. The fact that complication rates increase with the duration of the foreign bodies in situ is clear. Therefore, prompt bronchoscopy in patients with suspected airway foreign bodies is essential for lower complication rates.

The experience with treatment of acquired subglottic stenosis in 20 adults is reviewed. Nine of the 20 patients (45%) had opeated by other institues before treatment. Causes of the disease were 10(50%) of blunt neck trauama and 10(50%) of prolonged intubation. The most common associated airway diseases were nine patients (45%) of bilateral vocal cord fixations. Twelve patients (60%) underwent anterior cartilage grafts, five patients (25%) had anterior and posterior cartilage grafts and three patients (15%) had end to end anastomosis according to the severity of cricoid deformities and mucosal defects. Associated procedures were 9 patients (45%) of arytenoidectomy. Thirteen of 20 patients (65%) have been decannulated. Fe-male group was significantly higher decannulation rate than male group (p=0.0074). Decannulation rates were decreased from anterior cartilage graft group to anterior and posterior cartilage grafts group and to end to end anastomosis group (p= 0.00247), this finding suggested the patients with severe cricoid deformitiy were higher likely hood of failure because we selected the method used in this study according to the severity of cricoid deformities and mucosal defects. Our results support the more aggressive treatment is indicated for subglottic stenosis in adults.

Carotid body tumors are uncommon tumors of the head and neck Surgery is the primary treatment for the tumor. Large carotid body tumors frequently encircle the common, internal, and exernal carotid arteries, and extensive bleeding often complicates the resection, increasing the risk of carotid artery rupture and damange to major cranial nerves. Grafting should be used in high-risk patients. We have experienced a case of carotid body tumor which encircle the common, internal and external carotid arteries, treated with ligation of external carotid artery and grafting using Gortex between common carotid artery and internal carotid artery.

Background: Laryngeal cancer, the most common malignancy of head and neck, is being detected and treated in earlier and more effectively due to introduction of endoscope, continuous development of radiographic technology, and advancement in new surgical techniques such as laser surgery and conservation laryngeal surgery Objectives To compare the different treatment results for early laryngeal cancer to determine which methos provides the good prognosis. Materials and Methods: Retrospective study was done for 135 patients with early laryngeal squamous cell carcinoma(Stage I or II) who were treated at our institute between 1989 to 1996. There were 105 patients with glottic cancer(Stage I: 68 patients, Stage II:37 Patients) and 30 patients with supraglottic cancer(Stage I: 12 patients, Stage II:18 patients) Initial treatment included radiation therapy for 54 patients, endoscopic laser surgery for 8 patients, laryngofissure and cordectomy for 8 patients, vertical partial laryngectomy for 37 patients, supraglottic laryngecomy for 14 patients and supracricoid laryngectomy for 5 patiens, and total laryngectomy for 9 patients. Results : Salvage treatments, such as total laryngectomy, conservation laryngeal surgery, radiation therapy and neck dissection were performed for initial treatment failure with 9 patients after radiation therapy, 8 patients after conservation laryngeal surgery, 2 patients after endoscopic laser and 3 patients after total laryngectomy. Overall 3-year survival rate for glottic 71 was 92.4%, glottic f 84.3%, supraglottic 7172.7%, and supraglottic f was 63.%%. However, survival rate of the same stage was variable according to the choice of initial treatment. Conclusion New classification of the early laryngeal cancer was necessary and helpful for the choice of the initial treatment.

This article attempted to analyze how college student writers and their supporters interact in actual writing process. Focusing on how writers and supporters interact, usefulness of collaborative writing could be investigated. Participants were 37 junior students majoring Korean language education in the college of education and they learned theories about collaborative writing process. Researchers collected and analyzed participants’ texts, reflective journals, written brain storming materials, conversation maerials and so on. Study results showed that writers selected their supporters depending on their writing purpose and personal situation. And participants who had oral conversation made better results than who had merely written comments. Moreover, having interaction in planning and revising stage both was more desirable than in revising stage only. This study proposes that educators need to teach student writers how to interact supporters and how to accept others’ help in writing more than ever.

좋은 텍스트 요건에 대한 학습자의 인식과 쓰기 실행에 대한 연구

최건아(Choi Geon ah),김라연(Kim Ra yeon) 학습자중심교과교육학회 2018 학습자중심교과교육연구 Vol.18 No.3

본 연구는 학습자들이 좋은 글의 요건으로 인식한 내용을 본인의 작문에 어떻게 적용하는지 탐색하기 위한 목적으로 수행되었다. 연구에서는 먼저 내용 영역의 적절성을 고려하여 의학 칼럼으로 텍스트의 범위를 한정하고 의학 전공생들을 참여자로 선정하였다. 두 명의 연구자는 51명의 참여자들이 좋은 의학 칼럼의 요건으로 무엇을 들었는지, 그리고 자신의 작문에는 이를 어떻게 반영하였는지 분석하여 다음의 결론을 도출하였다. 첫째, 참여자들은 좋은 의학 칼럼의 요건으로 ‘독자 고려’, ‘가치’ 등을 포함하는 10가지 항목을 제시하였다. 둘째, 참여자들이 좋은 의학 칼럼의 요건을 적절히 인식하고도 이를 스스로의 작문에 적용하는 데 어려움을 겪는 것으로 확인되었다. 셋째, 참여자들은 적절한 요건을 인식하고 스스로의 작문에 이를 적용하기도 했으나 전체적으로 양질의 글을 생산하는 데 실패하기도 하였다. 본 연구에서는 쓰기 지식에 대한 인식과 실제 쓰기 수행 간에 존재하는 뚜렷한 차이를 확인하였다. 추후에는 학습자의 읽기와 쓰기에 영향을 주는 요건들이 더욱 세밀하게 연구되어야 할 것으로 보인다. The purpose of this study was to investigate how learners evaluate requisites for good texts and how they apply these requisites to their own composition. This study limited the scope of texts to medical column and collected medical students as participants considering the suitability of content area. Two researchers analyzed participants’ awareness of good medical texts and their own writing outcomes and found several traits. First, participants suggested ten categories of conditions for good medical column including ‘regarding readers’ and ‘value’. Second, some participants struggled to make use of their awareness of good texts in their writing. Third, some participants who even could aware and apply requites for good texts failed to make good texts. Researchers identified the gap between writing knowledge and authentic writing implementation. We need to inquire the traits and reflected factors on learners’ reading and writing more minutely.

The purpose of this study was to investigate the ways student writers use source texts for their own composition. In this study, 60 high school students read 5 source texts and wrote a text using informations in those source texts. This study found out that 10th grade students tended to focus on source texts which contain informations being strongly related to the writing task`s topic. The results of participants` evaluation of 5 whole source texts` usefulness, however, was not unanimous. Some students` reason to evaluate source texts was based on the existence of useful informations; on the other hand, some students focused on their own reading ability, personal interest or learning. Also, participants tended to evaluate the result of their information selecting practice negatively rather than positively and felt that they struggled to read source texts and to select informations. This indicates that many students did not have sufficient experience to use source texts to write information texts. Educators need to find out ways to help student writers use source texts and select information proficiently.

예비 초등 교사의 아동 도서 선정 기준에 관한 연구

최건아 ( Geon Ah Choi ),백혜선 ( Hye Sun Paik ) 청람어문교육학회(구 청람어문학회) 2014 청람어문교육 Vol.49 No.-

본 연구에서는 교육대학교 재학생 50명이 교육 활동에 쓸 아동 도서를 어떤 기준으로 선정하는지 분석하였다. 분석 결과, 참여자들은 크게 ‘도서에 권위를 부여하는 사회적 지표’, ‘초등학교 교육과정’, ‘예비 교사의 개인적인 독서 경험’, ‘예비 교사의 개인적인 교육 경험’, ‘아동 독자의 특성 및 교육 환경을 둘러싼 사회적 요구’, ‘아동 독자의 이해’, ‘아동 독자의 흥미’, ‘교육 제재로서 도서의 특성’, ‘태도 측면 교육’, ‘심동 측면 교육’ 등의 기준을 고려한 것으로 드러났다. 또한 문학 도서를 선택할 때와 정보 도서를 선택할 때 주목하는 요인이 서로 다른 것으로 드러났다. 참여자들은 다양한 기준을 사용해 도서를 꼽았지만 문학 장르에 편향하여 도서를 선정했다는 점, 도서 선정 목적에 어울리는 구체적 교육 방법을 제시하지 못했다는 점, 개인적 취향에 따라 도서를 선정하기도 한다는 점 등의 제한점도 드러내었다. 이에 따라 이들이 아동 도서 및 아동 독자의 특성을 더욱 잘 이해할 수 있도록 돕는 적극적인 교육 기회가 제공되어야 할 것으로 보인다 In this study, two researchers analysed how 50 pre-service elementary teachers select children’s books. Study results showed that the participants selected children’s books taking into account the ‘social indicators’, ‘pre-service teacher’s unofficial teaching experience’, ‘children readers’ nature and social needs’, ‘children readers’ comprehension’, ‘children readers’ interest’, ‘book’s trait as teaching material’, ‘attitude education’ and ‘behavior education’. And participants considered different elements due to the genre of the texts. Pre-service teachers considered various elements selecting books, there were, however, inadequacies that they couldn’t present proper teaching methods, overvalued literature books, focused on personal taste. Based on the results, this study proposes that pre-service teachers need active support to understand the traits of children’s books and children readers.

교양 국어 강의에 대한 대학생들의 평가 분석

최건아(Choi Geon-Ah) 한국리터러시학회 2013 리터러시 연구 Vol.- No.7

본 연구에서는 교양 국어 강의에 대해 대학생들이 어떻게 평가하는지 살펴보기 위하여, 교육대학교 3학년 학생 44명이 쓴 텍스트를 수집, 분석하였다. 연구 결과, 학생들은 작문에 대한 피드백, 작문의 장르, 쓰기 과제 수행의 부담, 학생의 참여 가능성, 동료와의 상호작용, 강의의 체계 및 운영, 교수자와의 래포 형성 등의 측면에 주목해 강의를 평가하는 것으로 드러났다. 교양 국어 강의의 목표와 학습자들의 요구, 특성을 고려하여, 향후 더 나은 대학 국어교육이 이루어질 수 있도록 노력해야 할 것이다. This study collected and analyzed 44 university students texts to investigate the way university students evaluate Korean language subjects in liberal education. Study results showed that university students evaluate subjects on the basis of feedback for composition, genre of composition, feeling pressure to write, students participation, system and manage of lecture and rapport with lecturers. We need to make an effort to construct better Korean language subjects in Universities considering the purpose of lectures, learners’ needs and traits.
