Content-based Instruction : Bridging the Gap Between What Students Can Do and What They Need to Do
김성연(Sung-Yeon Kim),Robin Berting 한국외국어교육학회 2005 Foreign languages education Vol.12 No.3
This study aims to examine whether or not sustained content-based instruction is associated with attainment of different levels of oral proficiency. For the purpose of the study, a sustained content-based course was designed for high level university students and implemented to a group of students whose oral proficiency ranged from lower-intermediate to advanced level. To test for the effects of the course on the students' oral proficiency, three different measures of spoken language proficiency were obtained via interviews: general English proficiency, content-specific English proficiency, and the combination of English proficiency and content knowledge. Results of the study indicated that all students, regardless of their proficiency, showed improvement in their oral proficiency, but that intermediate students made the most progress. The findings of the study suggest that Korean universities should implement more sustained CBI courses to cater to this advanced group of learners.
The East China Sea in DOD China Military Power Reports
( Bert Chapman ) 한국국방연구원 2017 The Korean Journal of Defense Analysis Vol.29 No.1
The National Defense Authorization Act of 2000 saw Congress require the Department of Defense (DOD) to prepare an annual report on Chinese military power. This report contains classified and unclassified editions. Documenting Chinese military developments, strategy, and trends are critical parts of these reports. Beijing`s military activities in the East China Sea (ECS) are important report components. This work explains the importance of these and other DOD reports for those studying ECS developments, examines how DOD has documented Beijing`s military activities within these publicly accessible reports, and describes how members of Congress have reacted to ECS developments during the Obama Administration.
News and perspectives on yolk sac stem cells
Bert Binas 한국수정란이식학회 2016 한국수정란이식학회 학술대회 Vol.2016 No.10
The mammalian yolk sac endoderm is an essential but understudied tissue that patterns and nourishes the embryo. This talk will present the isolation and characterization of several categories of rodent yolk sac endoderm stem cells. Specifically, we have isolated yolk sac endoderm stem cell lines from preimplantation embryos and from post-gastrulation yolk sacs. In both cases, we obtained two versions of stem cells that appear to differ in their degree of lineage maturation. I will discuss the relationship of these various isolates within the same species (rat or mouse), between species (rat vs. mouse), and with previously published isolates. I will then discuss potential applications in developmental biotechnology and toxicology as well as the human relevance of this research.

Future on-board vehicle control systems can be further improved through new types of mechatronic systems. In particular, these systems' capacities for interaction enhance safety, comfort and economic viability. The Automotive Engineering Department (fzd) of Darmstadt University of Technology is engaged in research of the mechatronic vehicle corner, which consists of three subsystems: sensor tire, electrically actuated wheel brake and smart suspension. By intercommunication of these three systems, the brake controller receives direct, fast and permanent information about dynamic events in the tire contact area provided by the tire sensor as valuable control input. This allows to control operation conditions of each wheel brake. The information provided by the tire sensor for example helps to distinguish between straightline driving and cornering as well as to determine μ-split conditions. In conjunction with current information of dynamic wheel loads. tire pressures and friction tyre/road, the ideal brake force distribution can be achieved. Alike through integration of adaptive suspension bushings, elastokinematic behaviour and wheel positions can be adapted to manoeuver-oriented requirements.

Let X1; : : : ; Xn be i.i.d. observations, where Xi = Yi + σnZi and the Y's and Z's are independent. Assume that the Y's are unobservable and that they have the density f and also that the Z's have a known density k. Furthermore, let σn depend on n and let σn → 0as n→ ∞. We consider the deconvolution problem, i.e. the problem of estimation of the density f based on the sample X1,..., Xn. A popular estimator of f in this setting is the deconvolution kernel density estimator. We derive its asymptotic normality under two different assumptions on the relation between the sequence σn and the sequence of bandwidths hn. We also consider several simulation examples which illustrate different types of asymptotics corresponding to the derived theoretical results and which show that there exist situations where models with σn→ 0 have to be preferred to the models with fixed σ
