This paper presents a case study of the effectiveness of debate class in promoting speaking skills of advanced learners. The researcher adopted English debate techniques in an English speaking class during four-week teacher training program and investigated how teachers responded to the new technique. Forty-five middle and high school teachers participated in the study and classroom observation, pre-survey, post-survey, and focus group interviews were used as the major research methods. The teacher pre-survey results presented that teachers prefer a conversation class where they can directly acquire proper sentence patterns and speaking strategies rather than spend time in performing communicative events. The results of the focus group interview and post-survey confirmed that a debate class can meet this specific teachers' needs. Most teachers responded positively to the debate classes since: 1) debate techniques are relatively new ideas to Korean teachers; 2) debate techniques require speed and accuracy in speech; thus teachers could learn to present their ideas logically and efficiently in a limited time through repeated argument exercises. The study result implies that debate technique can be an effective vehicle in an EFL context to promote advanced learners' logical thinking skills and logical English sentence structures.

We present the preliminary results of the pilot observations for the fringe survey at 43 GHz with the VLBI Exploration of Radio Astrometry (VERA). The main goals of the fringe survey are to establish a full list of phase calibrators for the VERA dual-beam astrometric observations, and for the KVN multi-frequency phase referencing observations. We performed two 24 hours experiments as a pilot observation to test the feasibility of the fringe survey. Each source from a list of 220 sources has been observed in one scan for 2 minutes. 67 sources were detected with the SNR threshold of 3.5. The correlated flux densities of the detected sources are presented in four ranges of projected baseline lengths.

We conducted a field survey of the generation and development of the delta area of the Nakdong River estuary, Korea. To examine deposition and erosion of the barrier islands, we observed the spatiotemporal variations of sediment transport and quantitatively estimated the settling velocity of coastal sediment. For the field survey, we established two survey sites off the coasts of Jinu Island and Doyodeung, which had shown rapid variations in deposition and erosion. At these sites, we measured the net surface elevation change of the bottom level at approximately 1-month intervals. Main findings were summarized as follows. (1) Calculated daily deposition and erosion velocity during the observation period ranged from -1.39 to 3.56cm/day at Jinu Island and from -4.0 to 3.07cm/day at Doyodeung, respectively. (2) Although two typhoons passed by the study area during the observation period, the maximum net surface elevation was larger in October than during the passage of those typhoons.

Objectives : This research identified the frequency and satisfaction level of the observation and performance practice during the clinical practice process conducted by dental hygiene students. With the goal of providing base data required for the development and operation of increasingly effective clinical practice program and for the improvement of the existing clinical practice training. Methods : The subjects in this study were 278 students of a university located in Masan. Survey comprised of 49 questions in 10 clinical practice domains was conducted. Results : 1. As for the observation practice by each grade, there was significant difference in oral radiology, pediatric dentistry, periodontology, oral surgery(p<0.05). As for the performance practice executed for each grade, there was significant difference in the oral radiology, preventive dentistry and oral surgery(p<0.05). As for the satisfaction level for each grade, there was significant difference in basic medical service(p<0.05). 2. As for the observation practice by each clinical practice institution, there was significant difference in oral medicine, oral radiology, preventive dentistry, prosthodontics, pediatric dentistry, orthodontics and oral surgery(p<0.05). As for the performance practice executed by each practice institution, there was significant difference in basic medical service, oral medicine, oral radiology, operative dentistry, prosthodontics, orthodontics, oral surgery(p<0.05). As for the satisfaction level by each practice institution, there was significant difference in the oral radiology, preventive dentistry, operative dentistry, prosthodontics, orthodontics, oral surgery(p<0.05). Conclusions : As for the satisfaction level for the clinical practice, basic medical service is the crimary care clinical practice which is most basic and that is executed the most in a dental clinic. Satisfaction level was the highest in the domains where there were extensive observation and practice frequency. By conducting observation and practice frequency in the clinical practice process by each clinical practice domain in a broad and diverse manner, it would be possible to improve the ability of the clinical practice trainees who improve their clinical work execution capability and satisfaction level on the clinical practice.

The purpose of this study is to examine the differences of perceptions of teachers and students regarding teaching skills. For the analysis, data was collected by ICALT(International Comparative Analysis of Learning and Teaching) class observation tool and students survey called My Teacher Questionnaire. a student survey. The data of teachers and students can be compared because as the two tools have seven common domains(Safe and stimulating learning climate, Efficient organization, Clear and structured instructions, Intensive and activating teaching, Adjusting instructions and learner processing to inter-learner differences, Teaching learning strategies, Learner engagement). In 2016, in Daejeon, Chungbuk and Chungnam. trained teachers collected data from 106 classes, and 2,866 students responded the survey. The reliability and validity of the two tools, class observation and MTQ(My Teacher Questionnaire) are proven to be satisfactory for use in Korean schools. Students perception on teaching was high, particularly when students are in lower grades and learning major subjects like English, Korean, and math. The domain of higher teaching skills, male students show higher perceptions while female students reported higher perceptions on lower-level teaching skill domains. To compare the perceptions of teachers and students, the predictive reliability of students engagement against teaching skill domains was used. Teachers showed higher predictive reliability on lower teaching skill domains while students showed higher predictive reliability on higher teaching skill domains. It is recommended for further study to develop a professional development model using a teacher class observation tool and the My Teacher Questionnaire for pre-service teachers and school teachers.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by this study included field measurement survey, and non-participatory observation from 8 child care centers in Seoul. The field measurement survey were conducted from February 20 to March 20, 2005, whereas non-participatory behavior observation were conducted from June 15 to July 10, 2005. The major results showed the following. 1) Most of child care centers were too small, did not use the adequate surfacing to play various activities, and were made of play equipment setting. 2) Child's play behavior focused on functional play activity and construction play activity. 3) The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction of play setting produced functional play behaviors on children. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.
