The purpose of this article is to present some strategies for teaching English listening comprehension in the general culture course of university. It considers what points of teaching effective listening may be examined : points such as the theoretical background, methodologies, the relationship between listening skills and phonetics, utilizing radio broadcasts and video tapes, the role of kinesic behaviour and improving the syllabus about listening comprehension. Finally, specific guidelines for integrating listening skills are outlined.

Listening Comprehension 학습 지도방안

최광현 全北大學校 敎育大學院 1993 敎育論叢 Vol.13 No.-

Reviewing the trends of English education in Korea tells us that the area of listening and speaking skills is allotted a smaller part of time and is taught later than the reading or writing areas. In this respect I suggest a systematic teaching method of stress, intonation and rhythm because it is very directly connected to the improvement of Korean student's command of English. I propose 10 ordered steps for teaching beginning learners and 6 orderd steps for intermediate/advanced learners, which are especially worthy of listening comprehension. Including the use of British and American songs, the use of Jazz Chants and so forth, we must improve this teaching method continually in order for this area to be integrated into the whole English teaching program.

In the semiconductor and optical industry the non-contact transportation is required for reducing the damages. The ultrasonic levitation is the solution of the problem. In this paper, the ultrasonic levitation system and 3 disk-type stator for levitation various object are proposed. The vibration modes of disks are analyzed with FEM and designed with the analysis results. The 3D vibration profiles of the disks are measured by Laser scanning vibrometer for verifying the vibration characteristics of the system. The amplitudes of the disks and the levitation heights of object are measured for evaluating the performance.

The equilibrium study has been made on the vanadium distribution between CaO-SiO_2-MgO_ast.-Fe_tO slag and liquid iron over the temperature range from 1540℃ to 1640℃. The vanadium distribution ratios(L_v) were approximately larger than phosphorous distribution ratios(L_p) by a factor of 10∼100 times. The L_v dependence on slag composition and temperature was found to be similar to the case of L_p. The vanadium distribution ratio increases with the slag basicity and Fe_tO content in slag, but decreases with the increase of temperature. A linear relationship was observed between logarithm of (V)/{[V][O]^n} (n=2 or 2.5) and (CaO+0.3MgO)/SiO_2. It is assumed that the vanadium ion is in the form of V^4+ or V^5+ in slag. The mutual function relating the slag components, F_s=0.58(CaO/ SiO_2)+0.025Fe_tO, was introduced to explain quantitatively the influence of slag composition on the vanadium distribution ratio. The log values of vanadium distribution ratio as a function of Fs were derived at the fixed temerature of 1590℃ and 1640℃.

An extremely rare case of primary melanoma involving only rectum is reported. This 59 year-old male patient was admitted to the hospital because of hematochezia, difficulty of defection. Endoscopic examination and radical excision showed polypoid lesion with ulceration which measured 6x6x3cm in 2cm from the anal verge. Histopathologic, H&E stain and electron microscopic examination(EM) were performed from endoscopic biopsies and excisional mass. We are reporting a case primary rectal melanoma with brief review of literature.

C-반응성단백과 가장 관련 있는 대사증후군 대사이상 항목

손중천,김범택,이득주,최현국,정현주,김광민 대한비만학회 2003 The Korean journal of obesity Vol.12 No.1

연구배경: C-반응성단백 (이하 CRP)은 심혈관질환의 예후인자 및 독립적 위험인자이다. 대사증후군은 복부비만, 고혈압. 당대사이상 및, 지질대사이상과 같은 관상동맥질환 위험인자들이 동시에 나타나는 증후군을 말한다. 저자들은 18세 이상의 성인 남녀에서 CRP와 대사증후군 대사이상 항목과의 상관관계를 연구하였다. 방법: 2002년 4월부터 10월까지 일개 대학병원 건강증진센터에 내원한 수진자 2772명 중 염증성질환이 의심되는 577명을 제외한 총 2195명을 대상으로 하였다. 신체계측과 혈압측정, 혈액검사를 실시하였다. 통계적 분석은 남녀를 구분하여 대사증루군의 대사이상 항목의 군집성에 따른 CRP값에 대해 ANOVA 검정을 시행하였고, 각 대사이상 항목들과 연령을 독립변수로 하여 회귀분석을 실시하였다. 결과: CRP는 남성에서 0.10 (±0.004) mg/dL, 여성에서 0.08 (±0.003) mg/dL로 남성이 여성보다 유의하게 높았다(p<0.001). 남녀 모두에서 CRP가 대사증후군 군에서 대사증후군이 없는 군보다 유의하게 높았다. 대사증후군의 대사이상 항목 수가 증가할수록 CRP값이 증가하는 양상을 보였다(P for trend<0.001). 남녀 모두에서 허리둘레 (남성 R²=0.132, 여성 R²=0.166)가 가장 높은 설명력을 보였다. 결론: 18세 이상의 성인 남녀 모두에서 CRP는 대사증후군 대사이상 항목들과 유의한 상관관계를 보였다. 대사이상 항목중 허리둘레가 CRP 수치와 상관관계가 가장 높았다 Background: C-reactive protein has been known as an independent risk factor and prognostic factor for cardiovascular diseases. Metabolic syndrome is a sum of coronary risk factors such as abdominal obesity, elevated blood pressure, hypertension, glucose intolerance and abnormalities in lipid level. The previous studies showed limited relationships between CRP and the risk factors in metabolic syndrome. We investigated the relationships between CRP and the risk factors in metabolic syndrome in adult men and women over 18 years old. Methods: This study included 2772 people. 577 people of them found to have inflammatory disease excluded. The anthropometry and blood pressure were measured. High sensitive CRP, Lipid profiles, WBC, and ESR were assessed. Results: CRP in Men (0.10 (±0.004) mg/dL) was significantly higher than that in women (0.08 (±0.003) mg/dL)(P<0.001). In both genders, CRP was significantly higher in people who have metabolic syndrome than in people who don't. As the number of risk factors increased, CRP was significantly increased (P for trend < 0.001). Waist circumference showed the greatest correlation with CRP in men and women (men; R²=0.132, women; R²=0.166) Conclusion: CRP was correlated with risk factors in metabolic syndrome in men and women over 18 years old. Of the risk factors waist circumference was most correlated with CRP.

In recent years, as the demands of VBNS and VDSL increase, the development of kernel parts of optical communication such as PLC(Planar Light Circuit), Coupler, and WDM elements increases. The alignment and the attachment technology are very important in the fabrication of optical elements. In this paper, the optical alignment characteristics of multi-axis ultra precision stage were studied. The alignment algorithms were studied for applying to the ultra precision multi-axis stage. The alignment algorithm is comprised of field search and peak search algorithms. The contour of optical power signals can be obtained by field search and the precise coordinate can be found out by peak search. Two kinds of alignments, such as 1ch. input vs. 1ch. output optical stack, and 1ch. input vs. 8ch. output PLC stacks were performed for investigating the alignment characteristics.

In recent years, as the robot technology is developed the researches on the artificial muscle actuator that enable robot to move dextrously like biological organ become active. The widely used materials for artificial muscle are the shape memory alloy and the electro active polymer. These actuators have the higher energy density than the electromechanical actuator such as motor. However, there are some drawbacks for actuator. SMA has the hysterical dynamic characteristics. In this paper the segmented binary control for reducing the hysteresis of SMA is proposed and the simulation of anthropomorphic robotic hand is performed using ADAMS.

페그인터페론과 리바비린 병합요법은 만성 C형 간염의 일차 치료법이다. 저자들은 만성 C형 간염 환자에서 페그인터페론 과 리바비린 병합 요법 중에 발생한 벨마비 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. 환자는 5년 전부터 만성 C형 간염을 앓아온 48세 남자이며, PEG-IFN α-2a 135μgm 피하주사 주1회와 하루 1200㎎의 리바비린을 투여하였다. 치료시작 후 9개월째 환자는 오른쪽 안면의 근력약화를 호소하였으며 벨마비로 진단되었다. 페그인터페론과 리바비린 병합요법을 지속하면서 관찰하였다. 환자의 벨마비는 페그인터페론 치료를 중단하지 않았음에도 3개월후 증상이 회복되고 이후 벨마비 재발 없이 현재 경과관찰 중이다. 만성 C형 간염에서 페그인터페론과 리바비린 병합 요법시 벨마비의 발생 가능성을 염두에 두어야 하겠다. A Case of Bell's Palsy Associated with Combination Therapy of Pegylated Interferon Alfa-2a (PEG-IFN) and Ribavirin for Chronic Hepatitis C Virus Infection Pegylated interferon alfa(PEG-IFN α) and ribavirin therapy is the first line treatment for chronic hepatitis C. Mild complications of the therapy are common, but more serious complications are rare. We report here a case of Bell's palsy that occurred in a patient with chronic hepatitis C virus infection during combination therapy of PEG-IFN α-2a and ribavirin. The patient was 49-year-old man with chronic hepatitis C (genotype 1b) for 8 years. He had compensated liver cirrhosis with splenomegaly. Therapy with PEG-IFN α- 2a 135mcg/week and ribavirin 1200mg/day was initiated. After 9 months of the therapy, the patient showed a loss of muscular tone on the right side of his face. A diagnosis of Bell's palsy was made. The Bell's palsy resolved over 3 months despite continuation of the combination therapy.
