This study was intended to examine the applicability of the pedagogic method Dictogloss to facilitating KSL students to develop their L2 listening and writing skills. First, we performed a comprehensive review of the literature in this field. According to the review, Dictogloss, in accordance with the teaching method of “Focus on Form,” combines listening and writing (reconstruction) activities with emphasis on cooperation and interaction among L2 learners for communication. Based on the literature review, we designed and performed a class of seven KSL students with Dictogloss. After the class, we believed that we could change the participants’ perceptions of listening and writing lessons from somewhat passive to active posture. To reconstruct the listening texts, they focused on the class with active and positive attitudes and learned practical writing methods. Despite the lack of a direct description and teaching process, we would like to claim that Dictogloss produced successful results: The participants could naturally understand and accept the composition and expression of the text. We concluded this study with some implications for the practice of Dictogloss for Korean education.

Background/Aims: Despite the many reports of colonoscopy complications worldwide, few studies have been performed at the population level in Korea. In this study, a population-based study was performed to evaluate the incidence of post-colonoscopy perforations compared to a control group. Methods: Between January 2011 and December 2011, data for all cases (age over 45) who underwent a colonoscopy were collected from National Health Insurance Service using a random sampling method. The clinical characteristics and perforation incidence (within 30 days after the colonoscopy) of cases were identified, and cases were then compared with controls who had not undergone a colonoscopy. Results: Among 1,380,000 subjects, 31,177 cases and 62,354 controls were identified. Perforation occurred in 14 patients (0.04%) in the case group and one patient (<0.01%) in the control group (RR, 28.0; 95% CI 3.7-212.9, p<0.001). Subgroup analysis was followed according to the endoscopic procedure, gender and age. In subgroup analysis, colonoscopy-associated perforations occurred more in the therapeutic procedure (RR, 26; 95% CI 1.46-461.46), male (RR, 50; 95% CI 2.96-844.41), and age of 45-60 years (RR, 30; 95% CI 1.71-525.23). Conclusions: A colonoscopy procedure is related to an increased risk of perforation at the population level. In addition, the therapeutic procedure, male, and

이광수(李光洙) 『무정(無情)』에 나타난 ‘반개(半開)’의 식민지적 형상 연구

김지우(金智祐) ( Kim Ji-woo ) 한국어문교육연구회 2021 어문연구(語文硏究) Vol.49 No.2

본 논문은 일본 식민주의를 정당화했던 ‘반개’ 개념을 통해 이광수 『무정』에서의 근대성 형상화를 설명하고자 한다. 삼각관계를 통해 형성되는 근대 계몽 주체 형식의 정체성은 전근대적 ‘야만’을 타자화하고 근대적 ‘문명’을 지향함으로써 성립하는 ‘반개’와 유사하다고 할 수 있다. 그러나 삼각관계를 해결하는 과정에서 ‘반개’의 허위성 또한 폭로되는데, 유교적 가부장제 속 영채의 희생과 선형의 순종을 필요로 하기 때문이다. 전근대적 ‘야만’을 배제하고 근대적 ‘문명’을 추구하는 ‘반개’가 도리어 전근대적 질서에 의존한다는 모순으로 인해, 형식은 ‘무정’했다는 죄의식에서 벗어날 수 없으며, 영채 또한 전통적 가치체계와 함께 사라지지 않는다. 작품의 후반부에서는 ‘반개’의 모순을 은폐하려는 시도가 이루어진다. 삼랑진에서 형식은 수재민을 ‘야만’으로 타자화하여, 근대 계몽 운동의 필요성을 강조하고 전근대와 근대의 이항대립을 강화한다. 이처럼『무정』은 식민지 조선에서의 근대지향성을 서사화하는 과정에서 마주하는 수많은 모순과 어려움을 보여준다는 점에서 문학사적 의의를 가진다고 할 수 있다. This paper aims to explain the novelization of modernity in Lee Kwang-su’s Mujeong (Heartlessness) through the concept of “semi-civilization” which justified Japanese colonialism. The identity of the modern enlightenment subject by Hyeong-sik is formed by a love triangle and it is similar to “semi-civilization,” based on the otherization of premodern “barbarism” and the pursuit of modern “civilization.” When the contradiction regarding the love triangle is solved, the falsehood of “semi-civilization” is revealed because Hyeong-sik needs the sacrifice of Yeong-chae and the obedience of Seon-hyeong in the Confucian patriarchy. In other words, “semi-civilization” rejects premodern “barbarism,” but in the same time it actually depends on premodern order. Due to this contradiction, Hyeong-sik cannot escape the guilt of being “heartless.” Yeong-chae also does not disappear with the traditional value system either. In the second half of the novel, attempts to conceal the contradiction regarding “semi-civilization” are made. In Samrangjin, Hyeong-sik otherizes flood victims as “barbarians” in order to emphasize the necessity of the modern enlightenment movement and strengthen the binary confrontation between premodernity and modernity. Therefore, Mujeong has literary significance because it reveals numerous contradictions and difficulties encountered in novelizing orientation towards modernity in colonial Chosun.

Entering 21 century of a knowledge-based society, the importance education has been growing. In particular, the University plays a significant role providing competitive knowledge to the individual as well as increasing national competitiveness to the countries. In Korea, the Universities have been gone through quantitative growth until there are more supply than demand; However, it is time to pursuit qualitative growth Over the past few years, a number of studies about educational programs were conducted, while the physical environment which accommodate the program were overlooked. The purpose of this study is to understand the usage habit and the spatial characteristics of campus environment and to analyze the usage satisfaction. The results of this study are as follows; The campuses surveyed had different size, different land types and different layouts. There were significant difference in satisfaction according to those spatial characteristics. The physical environment was classified into six factors which are outdoor environment, convenient facilities, support facilities, educational facilities, flow planning, and street environment. Among those six, the outdoor environment factor and convenient facility related factor were significantly related to the overall satisfaction. The green area, walkway, and symbol statue were the details of the outdoor environment factor, and the rest and indoor convenient facility were the details of the amenity factor. It was found that 4 campuses, the target of this study, had statistically different satisfaction and importance.

Domestic seafood has been widely used as a main protein source of the people, and demand for seafood is increasing year by year due to increase in national income and development of eating out culture. It is necessary to study to provide information to improve fishery income by improving efficiency and lowering inefficiency due to decline of earning of offshore fishery in recent 10 years. Both Stochastic Frontier Model and Data Envelopment Analysis were applied and the efficiency was compared and Wilcoxon test was conducted. Before the SFA analysis, the translog production function model was selected as a suitable model in this study. The estimation results of fishery production function show that the distribution of inefficiency follows a half-normal distribution, the technical inefficiency clearly exists in the production function, and the efficiency improves with time. In the DEA-SFA analysis, the average efficiency was estimated as 88% in the SFA, 49% under the Constant Return to Scale, and 70% under the Variable Return to Scale. As a wilcoxon test result, only one of 14 fisheries had commonality in fishery in the Constant Return to Scale. The yearly agreement of estimates were not consistent between SFA and CRS, while all the years showed the consistent estimates between SFA and VRS. Therefore, it was found that the estimates of SFA model should be considered to be consistent with those estimates in DEA model under the Variable Return to Scale.
