황희정 대한관광경영학회 2022 觀光硏究 Vol.37 No.4

The purpose of this study is threefold: to explore whether interactive discourse and languaging through task-based collaborative writing are effective in learners’ achievement of grammatical knowledge and in their accuracy for English language use; to identify how these activities are reflected in learners’ writing; and to find out changes in their perceptions and attitudes toward these activities. For this study, there were 36 students participated, who were placed into groups of three members. The class activities were divided into three phases. In the pre-task phase, participants were introduced how to perform their tasks, activated background knowledge about the tasks, and planned their tasks. During the task phase, for the essay writing task they brainstormed ideas on the topic, wrote essay, and gave feedback to each other. For the dictogloss task they listened to the text, reconstructed the text, and analyzed and corrected their errors for the final version. In the post-task phase, they retrospected the tasks regarding the linguistic forms, gave presentation to the class, and wrote languaginng. All the student participants completed pre/post tests and questionnaires, and they were interviewed after the post test and questionnaire. The present study showed the effects of interactive discourse and languaging through task-based collaborative writing on learners’ grammatical achievement and their linguistic accuracy. In addition, the study indicated that interactive discourse and languaging were reflected the most in their writng with respect to lexis-oriented LREs and syntax-oriented LREs. The study also revealed positive changes in learners’ perceptions and attitudes towards the class activities. The results of the study imply that collaborative writing and languaging activities should be worth utilizing in an Korean EFL classroom and that these activities need to be expanded.

The Relationships Between Language Anxiety and Corrective Feedback Effects in L2 Development

황희정 한국중원언어학회 2015 언어학연구 Vol.0 No.37

This study aimed to explore how differently language anxiety would mediate the effects of CF on learning the selected target L2 structures: English verb tenses, relative clauses, and comparative adjectives. The participants (n=122) from eight intact classes of an English conversation course were randomly assigned to three groups: the input-based group (TIE), the output-based group (DICT), and the control group (CG). Levels of language anxiety among the participants were measured by a language anxiety questionnaire with a four-point Likert. A pre-test and a post-test were conducted to measure the effectiveness of CF on learning the target L2 structures. After the post-test, follow-up interviews with students were conducted. This study found that the relationships between language anxiety and CF effects varied according to the target L2 structures. In other words, language anxiety positively affected learning English verb tenses, whereas it was negatively related to learning relative clauses. The interview results, especially from high-anxiety students in both the TIE and DICT group, indicated that CF did not provide an explicit clue on their noticing although it was helpful for their L2 learning.

황희정 새한영어영문학회 2005 새한영어영문학 Vol.47 No.3

제2 언어 습득의 언어입력(input)과 출력(output)의 역할에 대한 고찰황 희 정제2 언어 습득에서 언어 입력(input)과 출력(output)의 역할에 관해 지속적인 논쟁이 이어져 오고 있다. Krashen의 언어 입력에 관한 가설(input hypothesis)이 주요 쟁점으로 논의되고 있는 반면에, Krashen의 가설에 상반된 Swain의 언어 출력에 관한 가설(output hypothesis)은 소홀히 여겨져 왔다. Krashen의 가설은, 제2 언어 학습자가 목표 언어(target language)를 습득하는 과정은 그 학습자의 언어 능력이 현재 i 단계(at the current stage i)에서 문맥(context) 안에서 의미(meaning)를 이해할 수 있는 언어 입력(comprehensible input)을 통해 자동적(automatically)으로 다음 단계 i + 1 (the next stage i + 1)로 나아가는 것이고, 그러한 습득을 통하여 의사소통이 성공적으로 이루어진다는 이론이다. 한편, Swain의 가설은 제2 언어 습득은 구두(spoken)나 문자(written) 언어를 표현(produce)함으로써 이루어진다는 이론이다. 이 가설에는 연습(practice)을 통한 언어의 유창성향상 기능(enhancing fluency) 외 3가지 기능이 있는데, 인지 기능 (noticing), 가설검증 기능(hypothesis-testing), 메타 언어적 기능(metalinguistic)이다. 본 연구는 Krashen의 가설과 그와 관련된 이론들 (input processing, incidental learning)에 대한 쟁점들을 검토하고, Swain의 가설과 그 가설의 기능들을 살펴본 후, 기존 연구들을 근거로 언어 출력의 역할과 타당성을 제시하고자 한다. 아울러, 제2 언어 교수에 있어 바람직한 언어형태중심 지도법을 제시하고자 한다.

Background and Objectives: We assessed the ability of portable echocardiography (with contrasts) to clearly delineate the cardiacstructure, and evaluated the impact of its use on the diagnosis and management of critically ill patients in Korea. Subjects and Methods: We prospectively enrolled 123 patients (mean age 66±16 years), who underwent portable transthoracicechocardiography (with contrast) for image enhancement at 12 medical centers. The quality of the global left ventricular (LV) images, thenumber of the regional LV segments visualized, the ability to visualize the LV apex and the right ventricle (RV), and any changes in thediagnostic procedure and treatment strategy were compared before and after the contrast. Results: Of the 123 patients, 52 (42%) were using mechanical ventilators. The amount of poor or uninterpretable images decreased from48% to 5% (p<0.001), after the contrast. Before the contrast, 15.6±1.1 of 16 LV segments were seen, which improved to 15.9±0.6segments (p=0.001) after the contrast. The ability to visualize the LV apex increased from 47% to 94% (p<0.001), while the inability toclearly visualize the RV decreased from 46% to 19% (p<0.001). Changes in the diagnostic procedure (for example, not requiring othertypes of imaging studies) were observed in 18% of the patients, and the treatment plan (medication) was altered in 26% of patients afterthe contrast echocardiography. Conclusion: The use of a contrast agent during the portable echocardiography, in intensive care settings, can improve the image qualityand impact the diagnostic procedures and treatment for Korean patients.

과정 중심 글쓰기 활동 중 동료피드백이 학습자의 영작문 능력 향상에 미치는 영향과 인식에 관한 연구

황희정 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.6

This study aimed to explore the effects and perception of peer feedback on the improvement of learners’ English writing proficiency in process-based writing activities. 56 student participants were formed into two groups: 30 experimental group (PG) with peer feedback on their writing, and 26 control group (CG) without peer feedback. All students completed a process-based writing task and pre/post questionnaires. The questionnaires were divided into two categories: cognitive and affective areas and consisted of 30 questions including questions related to the general characteristics of learners. After they performed a 1st draft of writing, the students in each group were randomly divided into groups of three members. The students in PG rotated the drafts of each group members and exchanged peer feedback, and the students in CG read the drafts of each group members. They revised and completed the final draft. The study found that PG significantly improved in the final draft, which proved that peer feedback affected the improvement of learners’ English writing proficiency. It was also revealed that the students generally perceived peer feedback as helpful and showed positive changes in their attitude toward it. The findings imply that peer feedback should be valuable in process-based writing classes. Based on the findings, pedagogical implications were suggested. 본 연구의 목적은 과정 중심 글쓰기 활동 중 동료피드백이 학습자의 영작문 능력향상에 미치는 영향과 그에 대한 인식을 확인하는 것이다. 연구참여자는 56명의 대학생으로 동료피드백을 교환한 실험집단 30명과 동료피드백 교환하지 않은 통제집단 26명이었다. 모든 학생들은 과정 중심의 글쓰기 과제를 수행하였고 사전·사후 설문조사에 참여하였다. 설문 항목은 인지적 영역과 정의적 영역의 두 가지 범주로 나누고 학습자의 일반적 특성 관련 질문을 포함하여 30문항으로 구성하였다. 초안 작성 후, 집단별로 무작위로 3인 1조로 나누어 실험집단은 자신의 조에 속한 동료의 초안을 읽고 피드백을 교환하였고, 통제집단은 동료의 초안을 돌려 읽기만 하였다. 두 집단 모두 초안을 수정하여 최종안을 완성하였다. 연구 결과, 실험집단이 작성한 최종안이 훨씬 향상되었으며 이를 통해 동료피드백이 학생들의 영작문 실력향상에 효과적임이 입증되었다. 또한 두 집단 모두 동료피드백이 글쓰기에 도움이 되었던 것으로 인식하였고 긍정적인 태도를 보였다. 본 연구 결과는 동료피드백이 과정 중심의 작문 수업에 활용할 가치가 있음을 함의한다. 이러한 결과를 근거로 교육적 시사점을 제언하였다.

It is widely recognized that manipulation of body position takes advantage of the influences of gravity for improving oxygenation. The study aims to determine the effects of positioning(supine, prone, right lateral decubitus and left lateral decubitus positions) applied to the mechanically ventilatory acute respiratory failure patients on arterial oxygen partial pressure(PaO2) , alveolar arterial oxygen tension difference(AaDO2) , mean aterial pressure, peak inspiratory pressure and plateau pressure. Thirty two acute respiratory failure patients admitted to the medical intensive care unit at Kangnam St. Mary's Hospital. The Catholic University of Korea from March 1997 to January 1998, were divided into three groups by radiographic evidence of unilateral or bilateral lung disease. In group 1 with dominant right lung disease were twelve subjects, group 2 with dominant left lung disease had eight subjects and group 3 had twelve subjects with bilateral lung disease. The variables were measured in 30 minutes after each position of supine, prone, good lung down lateral decubitus and sick lung down lateral decubitus position. The position order was done at random by Latin squre design. The results are as follows; 1) With group 1 patients, the PaO2 in the left lateral decubitus and prone position were 126.8±30.8 mmHg and 106.7±36.8 mmHg, respectively (p = 0.0001). 2) With group 2 patients, the PaO2 in the prone and the right lateral decubitus position were 121.7±44.7 mmHg and 118.5±31.7 mmHg, respectively (p = 0.0018). 3) With group 3 patients, the PaO2 was 143.6±36.6 mmHg in the prone position (p =0.0001). 4) With group 1 patients, the AaDO2 in the left lateral decubitus and the right lateral decubitus position were 178.1 ±29.7 mmHg and 233.1±24.4 mmHg, respectively(p = 0.0001). 5) With group 2 patients, the AaDO2 in the prone and the left lateral decubitus postion were 184.0±39.5 mmHg and 231.0±23.9 mmHg, respectively(p = 0.0019). 6) With group 3 patients, the AaDO2 in the prone and the supine postion were 377.1±35.6 mmHg and 435.7±13.1 mmHg, respectively (p = 0.0001). 7) There were no differences among the mean arterial pressure, peak inspiratory pressure and plateau pressure for each of the supine, prone, left lateral decubitus and right lateral decubitus position. The results suggest that oxygenation may improve in mechanically ventilatory patients with unilateral lung disease when the position is good lung dependent and prone, and patients with bilateral lung disease when the position is prone without any effects on the mean arterial pressure and airway pressure. It is suggested that body positions improve ventilation/perfusion matching and oxygenation need to be specified in patient care plans.

황희정,이만영,윤호중,오용석,노태호,정욱성,박철수,최윤석,정우백,이재범,박현근,임근준,이재학 대한심장학회 2011 Korean Circulation Journal Vol.41 No.4

Background and Objectives: Several predictors of recurrence of atrial fibrillation (AF) after ablation have been identified, including age, type of AF, hypertension, left atrial diameter and impaired left ventricular ejection fraction. The aim of this study was to investigate whether the atherosclerotic plaque thickness of the thoracic aorta is associated with a recurrence of AF after circumferential pulmonary vein ablation (CPVA). Subjects and Methods: Among patients with drug-refractory paroxysmal or persistent AF, 105 consecutive (mean age 58±11 years, male : female=76 : 29) patients who underwent transesophageal echocardiography and CPVA were studied. The relationships between the recurrence of AF and variables, including clinical characteristics, plaque thickness of the thoracic aorta, laboratory findings and echocardiographic parameters were evaluated. Results: A univariate analysis showed that the presence of diabetes {hazard ratio (HR)=3.425; 95% confidence interval (CI), 1.422-8.249, p=0.006}, ischemic heart disease (HR=4.549; 95% CI, 1.679-12.322, p=0.003), duration of AF (HR=1.010; 95% CI, 1.001-1.018, p=0.025), type of AF (HR=2.412, 95% CI=1.042-5.584, p=0.040) and aortic plaque thickness with ≥4 mm (HR=9.514; 95% CI, 3.419-26.105, p<0.001) were significantly associated with the recurrence of AF after ablation. In Cox multivariate regression analysis, only the aortic plaque thickness (with ≥4 mm) was an independent predictor of recurrence of AF after ablation (HR=7.250, 95% CI=1.906-27.580, p=0.004). Conclusion: Significantly increased aortic plaque thickness can be a predictable marker of recurrence of AF after CPVA.
