        Morphological segmentation based on edge detection-II for automatic concrete crack measurement

        Tung-Ching Su,Ming-Der Yang 사단법인 한국계산역학회 2018 Computers and Concrete, An International Journal Vol.21 No.6

        Crack is the most common typical feature of concrete deterioration, so routine monitoring and health assessment become essential for identifying failures and to set up an appropriate rehabilitation strategy in order to extend the service life of concrete structures. At present, image segmentation algorithms have been applied to crack analysis based on inspection images of concrete structures. The results of crack segmentation offering crack information, including length, width, and area is helpful to assist inspectors in surface inspection of concrete structures. This study proposed an algorithm of image segmentation enhancement, named morphological segmentation based on edge detection-II (MSED-II), to concrete crack segmentation. Several concrete pavement and building surfaces were imaged as the study materials. In addition, morphological operations followed by cross-curvature evaluation (CCE), an image segmentation technique of linear patterns, were also tested to evaluate their performance in concrete crack segmentation. The result indicates that MSED-II compared to CCE can lead to better quality of concrete crack segmentation. The least area, length, and width measurement errors of the concrete cracks are 5.68%, 0.23%, and 0.00%, respectively, that proves MSED-II effective for automatic measurement of concrete cracks.

        대만인 한국어 학습자들의 어휘 학습 태도 및 어휘 학습 전략 양상

        왕청동 ( Ching Tung Wang ) 서강대학교 언어정보연구소 2014 언어와 정보 사회 Vol.23 No.-

        This paper has two aims. One is to examine the attitudes of native Chinese speakers towards learning Korean vocabulary. The study also attempted to examine the types of vocabulary learning strategies employed by native Chinese speakers. For this essay I followed Schmitt (1997) and conducted a survey. I found native Chinese speakers` awareness of learning attitude toward Korean vocabulary. At the same time, it investigated the strategies that learners used to acquire vocabulary. I found that successful learners efficiently use certain strategies. Therefore, we can utilize the successful strategies of native Chinese speakers to upgrade the teaching and learning of Korean vocabulary.

        타이완과 한국의 관광정책 및 방문객 현황

        WANG, CHING-TUNG 한국문화융합학회 2015 문화와 융합 Vol.37 No.2

        본고에서는 최근 몇 년간 양국의 관광산업 발전현황에 대해서 파악한 후 향후 타이완과 한국의 관광산업 발전노선에 대해 전망하고자 한다. 타이완의 관광정책은 국내외 환경변화에 따라 연도별로 변화를 달리하는 단계적인 정책을 추구하고 있다. 반면에 한국은 중앙에서 방안을 제정하고 시행하는 구조로 정부가 바뀌어도 전체적으로 일관성을 유지하는 정책을 펼치고 있다. 타이완과 한국 방문객 동향을 살펴보면 양국 모두 관광목적이 가장 높으며, 여성여행객 수가 많았다. 또한 상호 간의 방문객 수는 해마다 꾸준히 증가하고 있는 추세이다. 한국과 타이완은 과거부터 현재까지 역사적으로나 문화적으로 밀접한 관계를 맺어오고 있다. 또한 타이완 내 한류열풍과 한국 내 화류열풍은 그 강도에 있어서는 약간의 차이가 있겠으나 양국 국민의 관광교류에도 영향을 끼치는 것을 알 수 있다. 결론적으로 양국의 관광 정책은 서로 다르나 자국의 관광산업 유치와 발전에 다각도로 노력하고 있음을 알 수 있다. 이러한 양국 모두의 노력에 힘입어 향후에도 타이완과 한국 간의 상호 방문객 수는 계속 상승할 것으로 예측되며 문화 산업 교류 역시 빈번해질 것으로 보여진다. 이에 앞으로 양국이 상호 발전할 수 있는 협력체제를 갖추고 이를 바탕으로 양국의 문화 관광산업을 더 발전시켜 나가기를 기대해 본다.

        대만에서의 한류와 현지 통·번역 특화 교육 방안 모색

        Wang, Ching-Tung 한국외국어대학교 통번역연구소 2018 통번역학연구 Vol.22 No.4

        Currently, the popularity of Korean Wave (Hallyu) in Taiwan is actively promoting social, cultural and economic exchanges between the two countries. Reflecting these social phenomena, there are increasing numbers of people who need Korean talent in each field in Taiwan recently.At this point, it is necessary to cultivate Korean talents that will play an important role as bridgeheads in economic and cultural exchanges between the two countries, and it is essential to enhance national competitiveness. It should be noted that the Korean Wave in Taiwan is not a temporary phenomenon but has been steadily continuing from past to present and as the time passes, the derivatives industry related to Korean Wave develops more diversely. Although it is difficult to accurately determine the depth and direction of the impact of this phenomenon on Taiwan society in the future, If we look at the current situation, we believe that the demand for the interpretation and translation market is likely to increase day by day mainly driven by the industry. The purpose of this study is to explore the direction of indigenization education in order to improve Korean interpretation and translation ability for Korean learners in Taiwan in the future. For this purpose, I examined the current status of Korean language education, and Korean interpretation, translation education in Taiwan with the Korean Wave.

        Incidence and relative risk factors in posttransplant diabetes mellitus patients: a retrospective cohort study

        Ching-Yao Cheng,Yu-Tung Feng,Hue-Yu Wang 대한이식학회 2020 Korean Journal of Transplantation Vol.34 No.4

        Background: Posttransplant diabetes mellitus (PTDM) has a long-term impact on kidney transplantation outcomes, such as graft and patient survival. The incidence and risk factors of PTDM are well studied, but long-term follow-up results remain unavailable. We examined the long-term incidence and relative risk factors of PTDM. Methods: A hospital information system database for kidney transplant recipients (KTRs) for a transplantation center between 1983 and 2018 was used to perform this retrospective cohort study. KTRs with DM diagnosis and continuous use of hypoglycemic agents for more than 3 months were defined as having PTDM. Demographics and comorbidities before transplantation were also collected. Kaplan-Meier analyses were used to determine the cumulative incidence and relative risk factors. Results: A total of 296 PTDM cases were confirmed (28.46%) in this study. An increased cumulative incidence associated with age was noted, which was significantly increased in those aged ≥40 years. Male sex, hypertension, hyperlipidemia before transplantation, cytomegalovirus (CMV) infection, and tacrolimus-based regimens were also risk factors. No significant correlation was found between the development of PTDM and the increase of human leukocyte antigen mismatches, the primary causes of end-stage renal disease, and acute rejection. Conclusions: PTDM incidence was high in this cohort study. Characteristics such as age ≥40 years, tacrolimus use, comorbidity of hypertension and hyperlipidemia before transplantation, and CMV infection were associated with a high risk of PTDM. Monitoring and adjusting preventable risk factors such as CMV infection might be useful to prevent PTDM.

        Because of the Hallyu(Korean wave) blowing in the recent in Taiwan, Taiwanese tourists traveling to South Korea is becoming more and more. At the same time because of the drama produced in Taiwan so called ‘Hwaryu(華流)’ is gradually becoming popular in Korea fashion culture, The number of Korean tourists visiting Taiwan this occasion has grown noticeably. The fashion culture between the Taiwan-Korea two countries, Yet, there is no empirical data that analysis clearly how many affect for tourists between the two countries Trend, the causal relation is not clear, but, In general, the tourism industry and the fashion culture is being inferred that there is a correlation with each other. Thus, Taiwan and Korea take affect each other, doing mutual competition and promote the tourism industry of their own country. If so, How do Taiwan and Korean develop tourism routes for the future? In order to do this, to identify the current status of the tourism industry in Taiwan and Korea should be priority. then we can prospect the tourism development route for these two countries based on this data. This means, in order to nurture and develop the tourism industry in their country in the future. relationship between two countries through a more competitive form of mutual development must be prepared. Therefore, this study investigated the tourism policy and status of Korea and Taiwan, and analyzed the commutual visitors trends and features of Korean, Taiwan. to both Korea and Taiwan, tourism industry could develope country s economy and improve their quality of life, tourism industry should be the dynamic sectors for it. The international tourism income can be increased through tourism between two countries. also, it can activate international relations. In addition, From past to present Korea and Taiwan as the East Asian countries have been close relationship historically and culturally, Hallyu in Taiwan or Hwaryu in Korea, it may be some difference in the intensity, but, more and more, It is expected to have a significant impact on the tourism exchange of the these two nations. 본고에서는 최근 몇 년간 양국의 관광산업 발전현황에 대해서 파악한 후 향후 타이완과 한국의 관광산업 발전노선에 대해 전망하고자 한다. 타이완의 관광정책은 국내외 환경변화에 따라 연도별로 변화를 달리하는 단계적인 정책을 추구하고 있다. 반면에 한국은 중앙에서 방안을 제정하고 시행하는 구조로 정부가 바뀌어도 전체적으로 일관성을 유지하는 정책을 펼치고 있다. 타이완과 한국 방문객 동향을 살펴보면 양국 모두 관광목적이 가장 높으며, 여성여행객 수가 많았다. 또한 상호 간의 방문객 수는 해마다 꾸준히 증가하고 있는 추세이다. 한국과 타이완은 과거부터 현재까지 역사적으로나 문화적으로 밀접한 관계를 맺어오고 있다. 또한 타이완 내 한류열풍과 한국 내 화류열풍은 그 강도에 있어서는 약간의 차이가 있겠으나 양국 국민의 관광교류에도 영향을 끼치는 것을 알 수 있다. 결론적으로 양국의 관광 정책은 서로 다르나 자국의 관광산업 유치와 발전에 다각도로 노력하고 있음을 알 수 있다. 이러한 양국 모두의 노력에 힘입어 향후에도 타이완과 한국 간의 상호 방문객 수는 계속 상승할 것으로 예측되며 문화 산업 교류 역시 빈번해질 것으로 보여진다. 이에 앞으로 양국이 상호 발전할 수 있는 협력체제를 갖추고 이를 바탕으로 양국의 문화 관광산업을 더 발전시켜 나가기를 기대해 본다.
