( Jae Myung Goo ) 21세기영어영문학회 2014 영어영문학21 Vol.27 No.1

Recent interaction research has shown that corrective feedback may benefit L2 learners to varying degrees, and that certain types of feedback may be more beneficial than others, engendering much discussion and research attempts to investigate the issue. Goo`s (2012) study is one of those empirical attempts conducted in this line of research paradigm. The present study, as a conceptual replication of Goo`s original study, explores this on-going area of feedback research, the relative efficacy of different forms of corrective feedback, and whether/how phonological short-term memory (PSTM) mediates the impact of different feedback moves on the acquisition of the English that-trace filter. Twenty-nine adult high-intermediate Korean EFL learners were randomly assigned to one of three groups: a recast, metalinguistic feedback, and comparison groups. The study employed a pretest-posttest design. One intensive treatment session was implemented. Two dependent variable measures were developed/administered to assess learner performance: a timed grammaticality judgment test and a timed oral production test. Overall results showed that metalinguistic feedback was more effective than recasts at facilitating the acquisition of the target construction. PSTM was not found to be correlated with the effectiveness of recasts and metalinguistic feedback. Different patterns of learner performance were also observed depending upon the mode of dependent variable measure.

During a three-year period, 600 patients were admitted to the Asan Medical Center because of biliary tract diseases. Both aerobic and anaerobic cultures were performed in 313 patients with cholangitis (bile : 253, blood : 113, both : 53). Of these patients, 189 were positive(bile 159. blood 68. both 38). The most common organisms were E. coli, K pneumoniae, and P. aeruginosa in both bile(respectively, 49.7%, 20.8%, 51.5%) and blood cultures(respectively, 45.6%, 26.5%, 22.1%). Antibiotic therapy did not sterilize bile, but selectively increased the proportions of P. aeruginosa. There was no significant difference in biliary bacteriology according to the history of biliary surgery, or the presence of percutaneous biliary drainage or underlying disease. More than 95% of gram-negative organisms isolated was highly susceptible to imipenem and amikacin. P. aeruginosa was resistant to ceftazidime in 63.3% which might be associated with overuse of the drug during the study period. Further studies will be necessary in patients with cholangitis to determine whether newer antibiotics replace previous combination therapy.

This study was conducted to evaluate the response of CIDR-S on estrus synchronization of dairy goats and the effect of artificial insemination on conception rate. Estrus synchronization of sexually matured Saanen goats was induced with insertion of CIDR-S into vagina for 15 days and injection of 500 IU PMSG before removal of CIDR-S. Artificial insemination was conducted using liquid or frozen semen by intra-cervical insemination with synchronized does. Estrus synchronization was 90% using CIDR-S insertion for 15 days. Conception rate of inseminated does was 20% - 25%, while that of natural mated does was 100%. These results suggested that synchronization of dairy goats can be successfully induced and artificial insemination method has to be improved for the practical use in dairy goats.

Type of Feedback, Phonological Short-Term Memory, and L2 Development

구재명(Jae myung Goo) 한국영어어문교육학회 2014 영어어문교육 Vol.20 No.4

The present study examines whether and how the type of corrective feedback (CF) affects the level of L2 learning. Two CF moves, recasts and metalinguistic feedback, were compared in terms of their efficacy on the acquisition of the English mixed conditional. The study also investigated the role of phonological short-term memory (PSTM) in the effectiveness of the two feedback moves. Twenty-four high-intermediate university students were randomly assigned to one of three conditions: recast, metalinguistic feedback, and comparison groups. One intensive treatment session was implemented between the pretest and posttest sessions. Two types of dependent measures were employed: one grammaticality judgment test (GJT) and one oral production test (OPT). PSTM was measured via a nonword repetition task. Results showed that both feedback moves were facilitative of the development of the target structure. However, learner performance showed different patterns, depending upon the type of measure. In the GJT, recasts were found to have contributed more to the acquisition of the target, whereas in the OPT metalinguistic feedback was more effective than recasts at promoting the development of the target. Somewhat surprisingly, PSTM, unlike previous research, was not found to be correlated with learner performance on either measure.

N/A Background: Auscultation of lung sound is a fundamental component of physical examination of respiratory disease. It is difficult to teach lung sound to the medical student because of the observer variability and the lack of objective recording in auscultation. Multimedia education has became available in many fields due to rapid development of computer and its software. So we made multimedia program to teach the lung sound and evaluated the effect of this program on the self study of the lung sound hy medical students. Method: We developed the multimedia title Auscultation of lung sound by integrating lung sounds, wave form display, radiographic findings and some explanations about various lung sounds including normal and abnormal lung sounds. Thirty students attending in the 2nd year of Medical school at the Hallym University was randomly divided into two groups. Each group studied on their own using either tape or multimedia title for one week. After the study, they were tested to describe the lung sound of real patients who were admitted to the Chun Cheon Sacred Heart Hospital. Multimedia group was asked to answer the questionnaire on multimedia title. Results: 1) Test score of auscultation on real patients The mean score of tape group and multimedia group was 1.20±1.08 and 1.54±0.74 respectively. But there was no significant difference between two groups (P=0.34). 2) Summary of questionnaire Twelve out of 15(80%) students answered that multimedia title helped them to understand the lung sound and three students (20%) answered that this program was very helpful. For the visual display of wave form, eight out of 15 (34%) students answered that it was helpful and three out of 15 (34%) students answered that it was very helpful. Eighty seven percent of the students answered that visual display of sound wave form helped them to understand the lung sound. Fourteen out of 15 students answered that multimedia program was interesting and provocative, All student answered that they will recommend this title to other colleagues. Conclusion: Even though there was no stastical significant difference between two self study methods but student of multimedia group showed narrow range of score than tape group. Answer to the questionnaire sup- ported the usefulness of multimedia for the self study of lung sound. Therefore we conclude that this program is helpful in the self-learninig of lung sound for medical students.

N/A Objectives: Culture of sputum is apt to be contaminated through oral cavity and proximal airway. Therefore, identification of true etiologic agents by sputum culture is not always reliable. In order to differentiate the pulmonary infection from non-infectious disease and to identify the true etiologic agent of acute pulmonary infection, we used PSB(Protected Specimen Brushing) and evaluated the efficacy of PSB. Methods: In 168 patients with acute febrile illness with pulmonary infiltrations(male 106, female: 61, mean age: 49.5±17.6), we performed PSB via a bronchoscope and compared the results along with blood culture and sputum culture. Protected specimen brush was introduced through biopsy channel of bronchoscope and was rotated within the purulent secretions. Tip of the brush was severed with aseptic technique and was immersed in 1cc of Ringer's lactate solution and vigorously mixed for 1 minute. The specimen was submitted for quantitative culture within 15 minutes and was regarded positive culture if colony forming units were above 10³/ml. Results: Using PSB for the diagnosis of pulmonary infection, sensitivity was 71.1% and specificity was 84.296. PSB was helpful in identifing true etiologic agent among several potentially pathogenic organisms. Using PSB for the diagnosis of UAP (ventilator associated pneumonia), sensitivity was 72.4% and specificity was 100%. Conclusion: Use of PSB can be a helpful method for the diagnosis of pulmonary infection and identification of its etiologic agents.

English Relative Clauses: Are Korean ESL Learners Avoiding Them?

구재명 ( Jae Myung Goo ) 21세기영어영문학회 2012 영어영문학21 Vol.25 No.4

This study examined Schachter`s argument (1974) on ESL learners` avoidance behavior likely caused by L1-L2 differences. In this study of avoidance, eight Korean graduate students carried out two types of production tasks over four sessions: oral and written production tasks in Korean as well as in English. Five native speakers of English attending an American university and five native speakers of Korean living in Korea at the time of the experiment and receiving no structured English instruction also participated in the experiment as the English control group and the Korean control group, respectively. Results showed that the experimental participants had avoided using English relative clauses. The argument of their avoidance of English relative clauses is based on the evidential data that mirrored two compelling observations: (a) the rare occurrence of English relative clauses in the contexts in which they produced quite a few Korean relative clauses, (b) the rare occurrence in the contexts in which native speakers of English produced English relative clauses. Finally, it was also observed that such relative clauses as SU and DO relative clauses, which are higher on the accessibility hierarchy (Keenan & Comrie, 1977), accounted for the overwhelming majority of the relative clauses produced in all tasks, reaffirming the reliability of the accessibility hierarchy.
