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)

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.

The purpose of this study was to examine how a recently arrived male English as a second language (ESL) student’s social interaction processes changed as he moved from the periphery of the mainstream toward its core. Using the notions of From a Perspective of Community of Practice and legitimate peripheral participation proposed by Lave and Wenger (1991), this study described what identities, interactive practices, and interactive resources were available to him in a new milieu. Multiple sources of data were utilized, such as participant observation, fieldnotes, the participant’s conversation activities, interview, and the participant’s journal. The results revealed that his identities, interactive practices, and interactive resources were interrelated because he gradually increased his participation in interactive practices and gained access to a wide range of interactive practices and resources as he moved toward full participation in the mainstream.

In this site, TBM tunnel section was composed of weak-to-moderate fine sedimentation layer, mixing claystone with gypsum. Maximum advance rate of shield TBM hits a record of digging during the tunnel work period. It is to be compared the site's cycle time data with planning stage.

Throughout this basic study of the design items for standardization in foundation structures are suggested. Reliablity-based methods of desin skills and data analysis are suggested in this paper for standardization. Limit state design method for retaining wall structures are standardized as the National Design Guide.

A study on the limit state design method for retaining wall structures are reviewed based on the National Retaining wall Design Standard. In this paper several retaining walls are calculated according to LRFD design criteria analysis using the program and the factor of safety for sliding and overturning. Comparing with their results, the Taylor's series simple reliability analysis was performed. In the futures more study should needed including reinforced retaining walls, earth anchor structures. Geotechnical data also are evaluated beforehand.

In this study the evaluation of technologies for standardization in foundation structures are done. For this, reliablity-based methods of investiugation data analysis are suggested in this paper.

산악터널과 달리 도심지 지하도로는 대부분 평야지대에 위치하고 충적층이 두껍게 분포하고 있으며 특히 터널 입․출구부는 병렬터널로 분기되는 지점인 동시에 하향굴착을 하는 관계로 터널 시․종점의 위치선정에 따라 공사비에 미치는 영향이 매우 크게 된다. 또한 병렬터널의 필라폭(PW)은 지하 보상비와 직결 되기 때문에 병렬터널의 안정을 확보하면서 동시에 최소의 필라폭(PW)으로 터널을 계획하여야 한다. 국내 도로터널의 필라폭(PW)은 일반적으로 1.5D(D: 터널 최대폭)를 기준으로 하며 일부 터널의 경우 입․출구부 극히 한정된 구간에서만 1.5D(D : 터널 최대폭)이내의 필라폭을 적용한 사례가 있으나 보상비 문제가 아닌 선형계획측면에서 불가피하게 발생한 사례들이다. 본 논문은 NATM형식으로서 국내최초 도심지 지하도로 설계사례를 통해 선형 계획단계에서부터 지하 보상비 및 지반특성을 함께 고려하여 적정 필라폭을 설계한 사례를 소개하고 도심지 병렬터널의 적정 필라폭 결정방법에 대해 기술하였다. 적정 필라폭 결정은 설계 및 시공사례 분석과 수치해석을 통한 강도 감소법과 강도/응력비 방법을 이용하였으며 터널간 초근접으로 인해 필라의 안정성이 불량한 터널 입․출구부는 안정성 확보를 위한 보강 방법을 제시하고 수치해석을 통해 안정성을 확인하였다.
