Hwang, Sung-Sam, SeD, Hyo-Sun, Kim, Tae-Young. 2010. Korean English Teacher's Disempowerment in English-only Classes: A Case Study Focusing on Korea-specific Cultural Aspects. The Sociolinguistic journal of Korea 18(1). In this case study, we have focused on the disempowerment of a Korean English teacher (KET) in English-only classrooms. Six English as a foreign language (EFL) classrooms in a Korean high school were observed and analyzed by using interpretive discourse analysis. Out of the six classes, three representative classrooms were both video- and audio-taped. The results show that the English-only classes could weaken the KETs' power via three mechanisms: (a) calling the KETs' last name for choral greetings at the beginning of the class, (b) students' group solidarity and peer pressure between classmates, and (c) the students' excessively collaborative approach to peer assistance. It is argued that the exclusive English-only instruction disempowers the KETs' status and dismantles their vocational identity. In order to remedy the current situation, within a scaffolding supported by the eclectic use of first language where necessary for effective class management, KETs are empowered and overcome constraints imposed by the limited L2 oral competence of some non-native English teachers.

두께 1mm의 얇은 복합적층판의 자유경계단부에서 열응력으로 인해 발생하는 미세손상을 진동거동과 관련된 비파괴평가의 가능성을 연구하였다. 유한요소 열응력해석을 통해 예상되는 손상발생영역을 초음파 C-스캔과 광학현미경을 이용하여 관찰하였다. 사인 스윕시험을 이용한 적층보 시험편의 횡진동 해석결과, 미세한 내부손상으로 인해 고유주파수가 확실히 감소하였으며 감쇠비도 상당히 증가하였다. 길이가 짧은 적층보 시험편과 2차 모드의 공진주파수를 이용하여 얇은 적층판에서 열응력으로 유기된 미세손상을 매우 민감하게 평가할 수 있음을 알았다. A feasibility investigation on vibration-based nondestructive evaluation of thermal stress-induced micro failure in the free edge region of thin composite laminates(1mm thick) has been carried out. The failure occurrence and damage zone, which were predicted by the three-dimensional finite-element thermal stress analysis, were observed using the ultrasonic C-scan and optical microscopy. Analysis of the vibration spectrum measured from the laminate beam specimens by the vibration sweep test exhibited that the obvious decrease in resonancy frequency and some considerable increase in damping factor were associated with the micro-failure formation. The vibration technique utilizing short beam and high resonant frequency was found to be very sensitive to the thermal stress-induced damage in the thin laminates.

This paper describes results of the high gradient magnetic separation of iron from the blast furnace slag under conditions of the flow speed of 1-6㎝/sec, the particle size of under 74㎛, the magnetic field strength of 0-20 KOe and the loading that is feed weight/canister volume ratio of 0.17 - 2.26g/㎝. 1) The Iron captured rate from the blast furnace slag increases with decreasing flow speed and increasing the particle size and the magnetic field strenth. The experimental results agree well with Yashima. 2) The iron content of magnetic products in the blast furnace slag obtained by the high gradient magnetic separator was increased from 1.74%Fe to 5.93%Fe and that of non-magnetic products decreased from 1.74%Fe(raw material) to 0.9%Fe under conditions of the mean particle size of 16㎛, the flow speed of 4㎝/sec, the magnetic field strength of 15 KOe and the loading(feed weight/canister volume ratio) of 2.26g/㎤

The Purpose of this thesis is to seek the ideal divison of property in the case of divoce, and the Legal Valuation of wife's household affairs labor. The claim for division of property means that one spouse, when the marriage breaks down, can claim the division of matrimonial properties obtained by cooperation of both spouses. The Division of property System in the case of divorce was first introduced by the article 839-2 of the civil code from Janaury 1,1991. The property division naturally includes the element of liquidation, and also the element of support, but does not include the element of compensation. The most important and delicate problem is how to devide the marital property. It is determined by how much one has contributed to obtain and maintain the marital property. It is very conversial how much we should evaluate the contribution of houewife by her home-making service. And it is possible to exercise the various methods of division used in cases of co-owned property or inherited property.

Total Skin Electron Therapy(TSET) was used to treat superficially widespread skin legions such as mycosis fungoides and achronic progressive lymphoma. This paper described the dosimetry for the TSET at energy of about 6 MeV electron beams(Linear Accelerator, Siemens Mevatron KD) with dual field beams. The optimal conditions of the TSET were achieved when source skin distance was 500 cm, the angle between dual beams was 28^(。) and thickness of acryle filter was 0.8cm. At that time, the mean energy of electron beam was 3.8 MeV and the filed size of electron beam at the patients treatment plane was 180×100 ㎠. Within this rectangle, the uniformity of dose distribution was ±10% and the uniformity was ±5% except comer of the rectangle med. And the dose rate of the center was 11.7 cGy/min.

These days, the underwater excavation and the piling work have been commonly used to reclaim land and to build a breakwater. As the piling work generates high underwater sound pressure in all direction, various kinds of marine organisms are largely affected even if they live a long distance from the piling work. Therefore, this paper describes the relationship between the behavior of abalone(Haliotis discus hannai) of 50cm long and the environmental noise level with vibration due to the piling work. We have separated the research into two parts. The one is continuance impact, the other is intermittent impact. The following are the results obtained from the present investigation: Comparing 0.5cm/sec vibration with 50dB noise and 0.9cm/sec vibration with 60dB, the previous one show a faster reaction speed than the later one. Futhermore the later one showed that pulling up on their shell, in order to avoid the epidemic, moving around, small organisms are included to hide under big organisms, alerting posture. However we couldn't find a consistent standard in our research.

폐쇄성 수면무호흡 환자의 상기도 형태의 특징과 압력강하에 관한 3차원 전산유체역학해석

모성서,안형택,이정선,정유삼,문윤식,배응권,성상진 대한치과교정학회 2010 대한치과교정학회지 Vol.40 No.2

폐쇄성 수면무호흡(obstructive sleep apnea, OSA)은 수면 중에 반복적으로 상기도의 완전폐쇄나 부분폐쇄가 일어나는 질환으로서 흡기된 공기는 반드시 상기도라는 연조직 관(tube) 구조를 통과해야 하므로 상기도의 폐쇄경향은 관의 형태 및 관을 통과하는 공기의 유체역학적 특성에 따라서도 큰 영향을 받을 수 있다. 본 연구에서는 OSA 환자 3인의 치료 전 상기도 CT 이미지를 이용하여 개별화된 3차원 유한요소모델 A, B, C를 제작하고, 비공 당 170, 200, 230 ml/s의 흡기유량에 대하여 3차원 전산유체역학 해석을 시행하였다. 상기도의 유속, 음압 그리고 압력강하를 측정한 결과 관찰된 3개의 모델에서 모두 단면적이 가장 작은 부위에서 유속이 증가하였고, 음압이 크게 나타났다. 기도의 형태는 구개인두와 구인두 부위에서 좁아지는 형태를 가지며, 최소 단면적 영역과 하인두 단면적의 차이가 클수록 유속과 음압의 변화가 크게 나타났다. 비강 부위의 최고 압력과 최소 단면적 영역의 최저 압력의 차이를 의미하는 압력강하는 상기도 저항을 종합적으로 판단할 수 있는 유용한 지표이며, 유량에 따라 증가하였다. Objective: Obstructive sleep apnea (OSA) is a common disorder which is characterized by a recurrence of entire or partial collapse of the pharyngeal airway during sleep. A given tidal volume must traverse the soft tissue tube structure of the upper airway, so the tendency for airway obstruction is influenced by the geometries of the duct and characteristics of the airflow in respect to fluid dynamics. Methods: Individualized 3D FEA models were reconstructed from pretreatment computerized tomogram images of three patients with obstructive sleep apnea. 3D computational fluid dynamics analysis was used to observe the effect of airway geometry on the flow velocity, negative pressure and pressure drop in the upper airway at an inspiration flow rate of 170, 200, and 230 ml/s per nostril. Results: In all 3 models, large airflow velocity and negative pressure were observed around the section of minimum area (SMA), the region which narrows around the velopharynx and oropharynx. The bigger the Out-A (outlet area)/ SMA-A (SMA area) ratio, the greater was the change in airflow velocity and negative pressure. Conclusions: Pressure drop meaning the difference between highest pressure at nostril and lowest pressure at SMA, is a good indicator for upper airway resistance which increased more as the airflow volume was increased.
