Yang Tae-sun. 2013. Implications for EMCs: Based on Students' Perspectives. The Sociolinguistic Journal of Korea 21(3). The purpose of this study was to seek for better ways of implementing and expanding English Medium Courses (EMCs) at a university level through the lens of students. 6 male and 5 female students participated in this study and qualitative and quantitative data collection methods were used, such as journals, interviews, and students' English proficiency and such data were analyzed by a family of codes proposed by Bogdan and Biklen (1992). The results revealed that students generally felt that taking EMCs was beneficial for their future career, so they made an effort in taking EMCs. However, they revealed its downside, which eventually provided some insights on how to make this educational practice successful. First, students should increase their English proficiency to be comfortable in EMCs. Second, professors should refine their language and teaching skills to better serve EMCs. Finally, the university should implement and expand EMCs based on students' readiness for taking and professors' readiness for teaching EMCs. (158 words)

본 연구는 강우시 불투수성 지역에서 비점오염원 유출 특성을 분석하기 위하여 수행되었다. 불투수성 지역의 강 우사상 특성은 강우강도에 대한 영향을 많이 받는 것으 로 나타났으며, 강우강도가 크게 작용하면, 초기강우 현 상이 잘 일어나는 것으로 나타났다. 또한 선행무강우일수 에 의해서 비점오염물질의 농도차가 큰 것으로 나타나, 이에 대한 대책 마련이 필요할 것으로 판단된다. 불투수 성 지역의 비점오염원 유출 경향을 보면, 강우초기 유출 유량에 포함되어 유출되는 오염물질의 농도가 상대적으 로 매우 높게 나타났고, 일정 시간 경과 후에는 지속되는 강우에도 불구하고 오염물질의 농도는 증가하지 않고 낮 은 농도로 안정적인 유출경향을 나타내었다. 이러한 이유 는 건기 시 도로 표면에 집적되어 있던 오염물질들이 강 우시 초기에 유출되어 비점오염물질의 농도가 높게 나타 나는 것으로 나타났다. 불투수성 지역에서 발생하는 비점 오염물질 항목별 단위면적당 오염부하량은 매우 높은 값 을 나타내고 있는데, 이는 불투수성 지역의 특성상 아스 팔트로 되어 있는 도로 및 주차장, 교량 등이 있는 불투 수면이 대부분의 토양상부를 덮고 있기 때문에 강우시 불 투수성 지역 내 모니터링 지점에서 강우가 집중되어 유 출되기 때문에 비점오염물질의 유출이 증가하기 때문에 오염부하량이 증가한 것으로 판단된다. 강우시 초기세척 효과는 TSS의 경우, Event 1, Event 2에서 초기세척효과 가 매우 잘 관찰되었으며, TSS¤CODMn¤T-P 순으로 뚜 렷하게 나타나는 것으로 조사되었다. TSS와 CODMn가 가 장 민감하게 강우에 영향을 받는 것으로 나타났다. 이에 본 연구 결과를 통해 분석된 결과를 토대로 비점오염원 유출특성에 대한 다양한 데이터베이스를 구축하여 향후 비점오염원을 효율적으로 관리하는데 자료로 활용 가능 할 것으로 판단된다. 또한 비점오염원을 체계적으로 관리 하여 수계환경의 오염부하를 줄일 수 있는 방안을 강구 해야 할 것으로 사료된다.

Yang Tae-sun. 2012. University Students' Perceptions about NESPs and NNESPs in EMCs. The Sociolinguistic Journal of Korea 20(2). pp. 291-312. The purpose of this study was to investigate Korean university students' perceptions about NESPs (Native English Speaking Professor) and NNESPs (Non-native English Speaking Professor) in EMCs (English Medium Course) to suggest better ways to implement EMCs in university settings. 100 university students who had an experience in taking EMCs with both NESPs and NNESPs answered the questionnaire and 30 students out of them were also interviewed to consolidate the data. Students expressed that they could benefit from NESPs in the area of language. On the other hand, they thought that they could have more chances to broaden content knowledge with the help of NNESPs. Based on the results of the study, the following suggestions were made for NESPs and NNESPs to implement EMCs in a successful way: NESPs should deepen their knowledge of content areas. NNESPs should use a monitoring service at the university to get comments on their teaching, participate in one-on-one tutoring sessions to practice English with NESPs, participate in meetings to get effective teaching tips from experts, and the university should regularly conduct needs surveys and do ongoing analyses of students' and professors' needs to provide more customized EMCs.

This study analyzed the characteristics of stormwater runoff in the orchard areas and quantitatively estimated effluence of nonpoint source pollutants for the volume of runoff. Two target areas under vine cultivation were each 2,000㎡ and 1,800㎡, located in Gyeongju City. Since grape was the only crop on the target area, the characteristics of stormwater runoff at vineyard could be evaluated independently. A total of 51 rainfall events in the vineyard area during two years(2008-2009) was surveyed, and 19 of them became stormwater runoff, with rainfall ranging 16.5 - 79.7 mm and antecedent dry period of 1-13 days. The pollutant runoff loads by volume of stormwater runoff showed BOD ranging 19.5 - 45.3% in 30% of runoff volume. The average pollution discharge rate was 32.4%, indicating small first flush effect of BOD. The range of SS concentrations was 5 –52.0% in 10% of runoff volume, showing the average 28.7% of discharge rate, about 3 times more than rainfall effluent. TOC and TN appeared to be similar to the results of BOD, the average discharge rate of 30.9% and 30.6% for TOC and TN, respectively, for 30% of stormwater runoff volume. Average discharge rate of COD and TP in the same runoff volume was 35.1% and 36%, respectively, showing comparatively high discharge ratio. As the targeted vineyard area was permeable land, the pollution load ratio against rainfall-runoff volume appeared to be 1:1, implying no strong first flush effect for all the survey items.
