윤석화 ( Yoon Seok-hwa ) 대한영어영문학회 2011 영어영문학연구 Vol.37 No.3

This article is to investigate the improvement of listening ability through Movies. movies turn out to be an effective teaching device and very motivating to develop the EFL learners’ listening skills. Their capacity to arouse the English learner’ motivation to engage them in a variety of activities related to aural perception in the target language can hardly be denied. Hence, using correctly films can help boost motivation and increase students’ enthusiasm for English learning while helping them develop learning skills. The growing acceptance of content teaching within EFL context as a motivator for students has led in recent years to the frequent use of movies in English classes. For the purpose of the study, the researcher formulate two hypotheses, that there would be a significant enhancement in the listening ability and a strong relationship between listening and affective factors - confidence, anxiety, interest, participation, easiness, and willingness to use the expression in the movies. A written questionnaires asking the level of affective domain in Likert Scale were submitted to the students in class. Based the findings and conclusion formulated in this study, the following recommendations are hereby proposed. English teachers can use movies to enrich their teaching and enhance learners’ interests in learning English. English teachers should explore the other enrichment activities that could be used to teach the movies and overall linguistic skills. (WonKwang University)

ICT를 활용한 영어듣기 지도 방안

윤석화 ( Yoon Seok-hwa ),허준 ( Heo Jun ) 대한영어영문학회 2002 영어영문학연구 Vol.28 No.3

The purpose of this paper is to formulate the model of English listening instruction through ICT and its teaching scheme as a new approach for improving listening skill in our classroom. Above all, this model can provide the native speakers' vivid sound and enough multimedia-based listening materials for our students to increase their listening abilities. Especially, because it can serve as the base for other language learning, task-based listening instruction using ICT can help learners effectively transfer their listening skill not only to reading and writing, but also speaking through the interaction with the colleagues and the native speakers on the Internet. In the future, it is suggested that our researchers and teachers try to develop more effective English teaching-learning method using ICT, and that the Ministry of Education assist them financially or administratively. < Wonkwang University >

Background: Physical restraint is widely used to prevent self-harm and treatment interference in the intensive care unit (ICU)s, but it can cause adverse effects such as physical, psychological, and ethical problems. We examined the effect of nurse education on physical restraint use in the ICU. Methods: For 3 months before an ICU patient restraining program (IPRP), we investigated the application ratio of physical restraint, the incidence of complications and self-medical device breakage (self-extubation, self removal of intravenous line, etc.) Then we educated the 49 ICU nurses with an IPRP. The same data was collected again for 3 months after IPRP, and we also collected data from ICU nurses on their knowledge, attitude, and intention when applying physical restraint using questionnaires before and after IPRP education. Results: After IPRP education, the nurses` knowledge about physical restraint use improved significantly and their intension for restraint decreased. The physical restraint application ratio did not change significantly in the period before IPRP (146/475, 30.7%) compared to the period after IPRP (110/399, 27.6%). Significant decreases were shown in the incidence of physical injury and self-medical device breakage after restraint removal. There were no significant differences on the site, duration, or cause of physical restraints. Conclusions: Although the IPRP education did not decrease the restraint application ratio, there were significant decreases on patient physical injuries and medical device breakage after restraint removal. We suggest that education should be performed continuously to both nurses and doctors to decrease the application of physical restraints. (Korean J Anesthesiol 2008;55:590~5)

Background: The aim of this study was to investigate the effect of doxapram on recovery following propofol-remifentanil anesthesia. Methods: Forty patients scheduled for gastrectomy were randomly allocated to receive either doxapram 1 mg/kg or normal saline at the end of surgery under propofol-remifentanil anesthesia. Clinical recovery from anesthesia was assessed by times to spontaneous breathing, eye opening on verbal command, extubation, and discharge from the postanesthetic care unit (PACU). Bispectral index (BIS) values, blood pressure, and heart rate were recorded every 2 min for 16 min after the administration of doxapram or saline. The incidences of side effects were checked in the recovery room. Results: Spontaneous breathing was recovered after 6.2±1.1 minutes in the Doxapram group versus 9.2±1.8 minutes in the normal saline group (P<0.001). Times to eye and extubation were also shorter in the Doxapram patients than in the normal saline patients (6.9±1.0 and 8.1±1.7 min versus 10.4±2.0 and 12.0±2.6 min, respectively) (P<0.001). However, the times to PACU discharge were not different between the two groups (46.9±4.9 min versus 47.0±6.0 min, respectively). The patients in the Doxapram group showed higher mean BIS values compared with the normal saline group during emergence, but there were no differences in arterial blood pressure, heart rate and incidences of side effects between the two groups. Conclusions: Doxapram 1 mg/kg hastens early recovery from TIVA with propofol and remifentanil, and this emergence effect correlates with higher BIS values. Doxapram, however, does not affect the discharge time from the PACU and incidences of side effects. (Korean J Anesthesiol 2008;55:585~9)

본 연구에서는 취업 노인의 일자리문화 만족도를 높이고, 지속적인 향상을 통한 삶의 질 개선이 기여하고자 취업 노인의 일자리 만족도의 변화궤적을 살펴보고, 이에 영향을 미치는 요인을 규명하고자 하고자 하였다. 이를 위해 한국고용정보원의 고령화연구패널 조사 4차연도(2012년)부터 6차연도(2016년)까지 지속적으로 취업상태를 유지한 노인 477명의 자료를 분석하였다. 연구결과 첫째, 취업 노인의 일자리 만족도는 시점이 지날수록 증가하며, 초기치와 변화율의 개인차를 확인하였다. 둘째, 노인의 학력, 만성질환 개수, 우울, 소득과 자산, 직무에서의 신체활동 요구가 일자리 만족에 영향을 미치는 요인으로는 밝혀졌다. 셋째, 일자리 만족도 변화율에 영향을 미치는 요인으로 성별, 직무에서의 신체활동과 업무역량 요구가 영향을 미치는 것으로 나타났다. 이와 같은 결과를 바탕으로 노인의 학력수준에 맞는 취업기회의 확대, 건강상태가 양호하지 못한 노인에게 일자리 제공을 통한 경제적, 심리적 인정도모, 건강과 직무역량 강화를 위한 교육프로그램 확대를 제안하였다. The purpose of this studywas to investigate the change of job satisfaction of the elderly in order to increase the job satisfaction of the elderly and to improve the quality of life through continuous improvement. To this end, we analyzed the data of 477 elderly people who continued to work during the period from 2012 to 2012 (2016). The results of this study are as follows: First, job satisfaction of the elderly increases as the time passes, and individual differences in initial value and change rate are confirmed. Second, the educational needs of the elderly, the number of chronic diseases, the depression, income and assets, and physical activity demands in the job were found to be factors affecting job satisfaction. Third, the factors affecting the rate of change in job satisfaction were found to be influenced by gender, job activity and work capacity. Based on these results, we propose to expand the employment opportunities to meet the elderly "s educational level, to provide economic and psychological recognition through providing jobs to the elderly who are in poor health status, and to expand the education program for strengthening health and job competence.

Background: Currently, sevoflurane and remifentanil are utilized frequently for the inhalation induction of anesthesia. However, there is currently an insufficient amount of clinical data regarding the inhalation induction of sevoflurane after the administration of remifentanil. Methods: 80 patients undergoing elective surgery were allocated randomly to four groups. Group A inhaled only sevoflurane at 8 vol%. Other groups were administered 3 ng/ml of remifentanil and inhaled sevoflurane at 8 vol% (group B) or 6 vol% (group C) or 4 vol% (group D). All groups also received 0.6 mg/kg of rocuronium. The blood pressure and heart rate were measured at pre-induction, and before and after tracheal intubation. After operation, the patients` levels of satisfaction with the inhalation induction were evaluated. Results: The time to loss of consciousness was substantially longer in group D than in the other groups, but no significant differences were noted among the groups in terms of satisfaction scores. The HR in groups B, C and D increased significantly after pre-intubation as compared to baseline in group A. The HR decreased significantly during induction as compared to group A. The MAP in groups B, C and D decreased significantly at 1 and 2 minutes after tracheal intubation as compared to group A. In group D only, we noted no significant differences in the MAP as compared to baseline at 1, 2 minutes after tracheal intubation. Conclusions: 4 vol% sevoflurane was a more appropriate concentration for the inhalation induction of anesthesia when coupled with 3 ng/ml of remifentanil. (Korean J Anesthesiol 2009;57:170∼5)
