( Hyoung Joon Shim ),( Tae Yoon Lee ),( Young Koog Cheon ),( Chan Sup Shim ) 대한내과학회 2016 대한내과학회 추계학술발표논문집 Vol.2016 No.1

Background:?Coated SEMS (self-expandable metal stent) placement is the preferred therapy for malignant esophagorespiratory fistula (ERF) at present. Migration is more frequent in coated stent than uncoated stent. Migration can occur immediately after stent placement and is likely secondary to malpositioning, inadequate anchoring, soft nonconstricting tumors, or complete coating of the stent. The overall risk of migration is approximately 10%. To prevent migration, we have used the anchoring technique, called Shim’s technique in Korea, connecting stent to ear with silk thread.?Patients and Methods:?Seven patients with malignant ERF were included. ERF conditions liable to migration of stent were selected. The selection criteria were ERFs without stricture (3 cases), with short length of stenosis (2 cases), and with soft consistency around fistula (2 cases). The anchoring method was designed to hang stent to ear lobe. Auricle was used for a post to suspend stent by a thread until the fixation of stent on the esophageal wall. The coated stent was specially designed for antimigration which has small circumferential uncoated portion on proximal flange part of stent for fixation. After 5 days of stenting, we removed the anchoring silk from the stent. Sealing of fistula were assessed with clinical improvement and esophagogram.?Results:?There were no migrations after stent placement in all 7 cases. Symptoms of aspiration were improved in all 7 cases.?Conclusions:?The anchoring technique was useful for the prevention of stent migration in esophagorespiratory (ERF) cases, especially in the conditions that stent are apt to be migrated.

Towards an Understanding of Teachers' Mediation in English Language Teaching in the Primary Schools

Shim,Kyu-Nam 한국초등영어교육학회 2009 초등영어교육 Vol.15 No.2

This small-scale study aims to investigate how primary teachers of English perceive their role as mediators with regard to English teaching. Thus, it examines the teachers' current mediation principles and their perceived practice. This study also sets out to gain an in-depth understanding of further issues which emerged from the dissonance between the teachers' beliefs and their perceived practice of mediation. In order to conduct the research, a mediation questionnaire was adopted from Williams and Burden (1997), and another open-ended questionnaire was constructed to obtain the qualitative data from 22 participants who are teachers of English and are in a Master's degree program. The results of the study reveal that generally teachers hold and exercise their own beliefs regarding their role as mediators. However, they do not put some of their principles into practice. A number of significant factors were found to be responsible for this, these are: unfavorable teachers' working conditions, dedication to the national curriculum, and their awareness of certain mediation principles. Some particular areas needing further investigation were identified in the last part of the study.

Shim,KyuNam,MIn,Deok-Gi,Lee,Seungmin 한국초등영어교육학회 2012 초등영어교육 Vol.18 No.3

This small-scale study aims to try out if an educational robot can be used as an interlocutor in the formative speaking assessment in the primary English learning classrooms. Also it aims to investigate if it could affect the learners’ emotional factors such as motivation and confidence. For these purposes, firstly, a number of theoretical issues were investigated: Difficulties of speaking assessment, principles of speaking assessment, and robot technology; secondly, the educational standards of speaking skills prescribed in the national curriculum were examined. Through which, a model of robot-assisted speaking assessment was developed and applied to the primary school students. In addition, a questionnaire survey and an interview were conducted to 13 students for the purpose of obtaining the quantitative and qualitative data regarding their emotional responses to the assessment. The results indicate that the model of robot-assisted assessment might be put into assessment practice. There are, however, still some obstacles which need to be addressed. First, the robot should be equipped with some more high-technologies such as space and voice recognition for human-robot-interaction(HRI). Second, it should also be equipped with a number of programs such as text-to-speech(TTS), speech-to-text(STT), radio-frequency identification(RFID), and tele-presents in order to allow robots to communicate with the students. Lastly, item pool of speaking assessment should be developed thought which, the teachers could access it without any difficulties. Finally, a pedagogical implication is presented based on the research results.

An investigation into teachers’ perceptions of the national achievement test of primary English

Shim,KyuNam,Lee,WonKey 한국초등영어교육학회 2011 초등영어교육 Vol.17 No.3

The purpose of this study is to investigate how primary school teachers of English perceive the national achievement test of primary English (hereafter NATPE). It also aims to investigate to what extent the washback effect of NATPE has on teachers' practice in their teaching. For these purposes, the teachers’ usual way of teaching was surveyed, and an NATPE test contents were analyzed from the perspectives of teachers. From this analysis, some critical issues were raised, such as the dissonance between what the teachers do before and after the test implementation, and the impact of the test on the teachers' perception and their practices. To carry out the research, a questionnaire consisting of some open-ended questions and some close-ended ones was administerd to over 100 teachers from different areas. An in-depth interview was also conducted to 15 questionnaire respondents in order to consolidate the data obtained from the questionnaire. The results indicate that teachers do not have enough information about the NATPE in terms of the four level distinctions of English achievement, and the differences between the neighbouring levels, the way of determining the cut-off point of each level. The results also show that teachers made efforts by employing a number of methods and strategies to help students prepare for the test, and compensate for their weakness after the test.

An Analysis of Less-able Students’ Motivation in their English Learning in the Primary Schools

Shim,Kyu-Nam 한국초등영어교육학회 2010 초등영어교육 Vol.16 No.1

This small-scale study aims to analyze how less-able students in the primary schools perceive certain components of motivation with regard to their English language learning. Thus, it examines the less-able students’ current perception of their English language learning. In order to conduct this research, a close-ended questionnaire was adopted and quantitative data of 81 participants were obtained from ten primary schools; then factor analysis and multiple regression analysis were carried out. The results of the study reveal that generally there are two major components which have an effect on the participants’ motivation with respect to their English language learning: intrinsic motivation and parents. While having relatively low intrinsic motivation, the participants are generally encouraged to learn English in order to meet their parents’ expectations. A number of significant minor components were also found to be responsible for the participants’ motivation such as the participants’ self-efficacy and teachers. Tentative implications and recommendations for the development of the less-able students’ motivation regarding English language learning are discussed in the towards the end of the study.

이 논문은 이익과 현금흐름의 예측정확성을 비교하는 것을 목적으로 한다. 일반적으로 이익의 예측정확성에 대해서는 많은 연구가 이루어져 왔지만, 현금흐름의 예측정확성에 대해서는 연구가 거의 없는 실정이다. 이 연구는 연구할만한 주제이다, 왜냐하면 현금흐름은 기본적으로 이익과 더불어 회계에서 중요한 경제적 변수이며, 현금흐름의 예측정확성 연구는 이익 및 발생액과 밀접한 관련이 있기 때문이다. 따라서 현금흐름 예측정확성연구는 그 의미가 크다할 수 있을 것이다. 연구결과에 의하면, 현금흐름 예측정확성은 이익의 예측정확성보다 못하였다. 즉 현금흐름 예측오차가 이익예측오차보다 크게 나타난다. 이러한 결과는 발생액 때문일 수 있다. 발생액이 미래이익예측에 유리하게 작용했을지도 모른다. 그 외에, 어떠한 변수들이 현금흐름 예측정확성에 영향을 주는지 회귀분석을 해 보았다. 이때 독립변수들은 이익예측에 영향을 주는 변수들을 그대로 사용하였다. 연구결과, 모든 독립변수들이 현금흐름 예측정확성에 유의한 영향을 보이지 않았다. 이러한 결과에 대해 이익예측 정확성에 미치는 영향요인이 현금흐름예측정확성에 미치는 영향요인과 다르기 때문일지도 모르는 것으로 해석된다. 향후 이 부분에 대해 더 깊이 있는 연구가 필요할 것이다.

Yun Bai and Jaewoo Shim. 2021. English Pronunciation Self-efficacy Sources and Pronunciation Proficiency of Chinese College Learners. Studies in Modern Grammar 109, 105-126. The purpose of this study is to investigate the relationship between the four sources of English pronunciation self-efficacy and English pronunciation proficiency of Chinese college learners of English. A sample of 429 English majors at a college in China was selected. The test scores from a read-aloud task were used as the measure of subjects’ English pronunciation proficiency. The questionnaire was used to collect the data of four English pronunciation self-efficacy sources. The Pearson correlations showed that the four sources were correlated significantly with English pronunciation proficiency. The multiple regression analysis showed that 45% variance in English pronunciation proficiency was explained by the linear combinations of the four sources; however, the nominal variable of gender was not statistically significant in explaining the variance in English pronunciation proficiency. Overall, the significant relationship between English pronunciation self-efficacy sources and English pronunciation proficiency was observed in the present study. Pedagogical implications for teaching English pronunciation were discussed based on the results.

『 詩와 賦의 系譜考』 (下)

張深鉉 成均館大學校 1962 論文集 Vol.7 No.-

The papers deal with the genealogies of Shi-jing (詩經) and Ci-fu (辭賦). I denying the former opinions the Fu (賦) was a variation of Shi, have brought it to light that the Shi and Fu had been originated and developed on the different lines. The former is the rhythmed verse originated from Shi-jing and developed fully in T'ang dynasty and the latter is the free-verse originated in the south China and developed on a peculiar line into Ci-fu in Han dynasty. I accordingly, deny the opinion that Shi-jing was followed with Ch'u-t'zu, that cause them to mistake the free-verses on the course of Ch'u-t'zu of the south, Sun-tzu-fu (荀子賦) , Lu-fu (律賦) in T'ang and Sung-t'zu (宋詞) as variations of Shi-jing. Finally I conclude that genealogies of Chinese verse to be separated rhythmed verse of Shi and Free-verse of Fu.
