This study was conducted by collecting and analyzing curricula of 19 colleges that has the department of dental laboratory technology throughout the country and analyzed by use of a questionnaire designed by the researcher with regard to details of actual operation in each college. Credit points for clinical training that has been conducted based on curricula vary from 3 to 20 points depending on colleges. But around 10 credit points are considered as ideal. For evaluation, the evaluation table was not applied but used as reference only. As criteria for evaluation such as evaluators, evaluation items and criteria for point distribution do not provide objectivity or reliability, development of accurate evaluation tools is required. It dis necessary for the bodies of colleges to maintain a level of mutual trust by visiting the sites of practical training regularly for the formation of progressive industry-academia cooperative relationships. When selecting the sites of practical training, it would be desirable to look for sites with better conditions for practical training in conjunction with related institutions. Besides, regarding clinical training education, in order for students to adapt themselves correctly to work environments and rapidly cultivate practical capabilities at site, systematic and efficient operation of training sites is required.

혈액질환 가운데 결핵 발생이 증가한다고 알려진 것은 호지킨 림프종을 포함한 림프증식성질환 그리고 모양세포성 백혈병 등이 있다. 또한 동종 골수이식을 받은 환자에서도 결핵은 증가한다고 알려져있다. Kaplan 등은 골수구성 백혈병 환자에서 결핵 발생이 증가한다고 보고하였다. 그러나 골수구성 백혈병 환자에서 결핵의 발생이 증가하는 이유에 대해서는 아직까지 정확하게 밝혀지지 않았다. 저자들이 2년 동안 후향적으로 조사한 180명의 성인 골수구성 백혈병 환자들 가운데 결핵이 발생한 환자는 4명이었고, 발생 부위는 모두 림프절이었다. 결핵은 골수구성 백혈병의 특정 아형에만 국한되어 발생하지 않았지만, 50%에서 FAB 분류에 의한 M4였다. 림프절이 종대된 골수구성 백혈병 환자에서 특히, 결핵의 유병율이 높은 나라에서는 결핵성 림프절염도 감별진단에 포함시켜야 한다. During the neutropenic phase, leukemia patients receiving chemotherapy are prone to bacterial and, fungal infections; occasionally mycobacterial, viral and protozoal organisms may also cause infections. Mycobacterium tuberculosis infection was reported very rarely in these patients. This report describes four patients with M. tuberculosis infection identified from 185 adult patients who were diagnosed myelogenous leukemia between January 2003, and December 2004. There was no patient with M. tuberculosis infection from 44 lymphoid leukemia and 11 acute biphenotypic leukemia patients. Sites of infection were all lymph nodes. Three among four patients were presented with lymphadenopathy at initial diagnosis of leukemia, and the other one presented with lymphadenopathy after induction chemotherapy. There was no patient presented with lymphadenopathy during the neutropenic phase. Tuberculous lymphadenitis was presented in a patient with three acute myelogenous leukemia (FAB class 2 M4, 1 M2) and a chronic myelogenous leukemia, accelerated phase. An acute myelogenous leukemia patient had a leukemic cell and tubercle bacilli in the same lymph node. Tuberculosis should also be included as a differential diagnosis in myelogenous leukemia patient with lymphadenopathy, especially in the countries in which the disease is endemic.

Acute unilateral airway obstruction may be developed immediately after general anesthetic induction. Tracheal intubation is essential procedure to support lives for who is coma or undergo general anesthesia, but several complications could occur. One of these is airway obstruction immediately after endotracheal tube insertion because of bronchial mucous plug, previous aspirated foreign body, hemoptysis ect. This acute bronchial obstruction may be manifested clinically by hypoxemia, cardiovascular instability, brain damage, if more aggravated to death due to partial or complete interruption of ventilation to an lung. Therefore if endotracheal tube obstruction may occur, early detection and treatment is very critical. A 53-year-old male patient underwent acute unilateral obstruction of bronchus immediately after inserted endotracheal tube, so he revealed hypoxemia, hypotension, but smooth operation and anesthetic care was progressed overall owing to endotracheal tube suction and replacement of tube.

The purpose of this study was to investigate the effect of knee exercises on the onset times of vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) and in healthy subjects. Fifteen subjects (7 men, 8 women) in a mean age of 25.4 years participated in the study. Electromyographic (EMG) signals were recorded from the VMO and VL under four exercises. Knee exercises consisted of open kinematic terminal knee extension, straight leg raising, isometric hip adduction exercise, and closed kinematic terminal knee extension. No significant differences were found in the onset times of EMG activities of VMO and VL in the four exercises. There were also no significant differences among the exercises. These results coincided with previous studies that found no difference between onset of VMO and VL. However, it is difficult to say that there is no difference between onset of VMO and VL in healthy subjects. To confirm this results, further researches that follow same onset determination metod and exercises are needed. Not only is the study of onset time of muscle needed, but also the studies of the amount of activation and the rate of increase of muscle activation are needed.

Chromium occurs naturally in the earth's crust as well as in air, surface, and ground water. However, chromium is released to the environment in much larger amounts as a result of human activities. Hexavalent chromium, Cr(Ⅵ), is very soluble in water in natural environment and very toxic, carcinogenic, and mutagenic in animal and man. On the other hand trivalent chromium, Cr(Ⅲ), is less toxic and less soluble and thus is a lesser problem. This study has been carried out in order to reduce toxicity of Cr(Ⅵ) by an Escherichia coli strain. After adding E. Coli., the results were obtained from concentration of total Cr, Cr(Ⅵ). Cr(Ⅲ), pH, turbidity, and VSS in aerobic condition was summarized as follows : After 48hr aerobic condition in experiment of synthetic wastewater, the reduction rate of Cr(Ⅵ) was 20%. Also, the reduction rate of Cr(Ⅵ) was 60% in experiment of raw wastewater.

The acid value (AV) as well as the ester value of essential oil is an important index to evaluate quality of essential oil. The official standard analytical method of KS H ISO 1242 dealing with “Essential oils - Determination of acid value” was assessed experimentally using two lavandin essential oils obtained in France as an example. One French lavandin oil sample showed the results of AV= 0.9 by both indicator method and potentiometry. Another sample showed AV = 1.9 by indicator method and AV = 1.6 by potentiometry. Latter lavandin oil sample exhibited significantly higher acid value than maximum value of 1 described in the standard. This result suggests that latter lavandin oil was contaminated, because this oil was contained in an orange juice bottle. Results of this study proved that KS H ISO 1242 could be used as a suitable scientific standard for the determination of acid value of essential oils.

본 연구의 목적은 비행시험으로부터 항공기의 동적 세로 안정 미계수를 결정하는 것이다. 일반적으로 미계수를 결정하는 방법은 풍동시험 방법, 분석적 방법 그리고 비행시험 방법등으로 나누어진다. 앞의 두가지 방법은 미계수 추정에 있어 많은 제한을 갖고 있으며 추정된 미계수의 유효성에도 문제가 있다. 따라서 비행 시험은 가장 정확한 미계수를 얻을 수 있는 방법이며 반드시 필요한 절차이다. 쌍발 복합재 항공기의 비행시험을 통해 자료를 획득하였고 최대공산법을 이용하여 세로 조종/안정 미계수를 추정하였다. 추정된 미계수를 이용하여 항공기의 운동을 시뮬레이션하여 실제 시험자료와 비교하여 좋은 결과를 나타냄을 알 수 있었다. The purpose of this paper is to find how to determine the longitudinal controllability and stability derivatives from flight test and to display the longitudinal stability of the Twinbee aircraft. There are various methods developed to find the derivatives : wind tunnel testing, predicted result from empirical data, flight test and so on. Among those methods, the estimation from flight test of real aircraft is the most reliable. We performed the flight test of Twinbee and recorded the states of aircraft. Using those states and parameter estimation algorithem based on the Maximum Likelihood (MMLE) criterion, we can estimate the controllability and stability derivatives. In this paper, we will show the process from designing the proper flight test input to estimation of derivatives.

This research takes up DONG HWA(桐華) temple, PA GYE(把溪) temple, UN HEA( 銀海 ) temple, UN BU(雲浮) temple, and the HWAN SUNG(環城) temple, which makes clear the space structure and the belief form of those Buddhist temples. The above-mention temples have been already investigated in other research's. However Now day, The temples are a lot of changes so it is necessary to clarify the current situation. Moreover Each Buddhist temples was not investiaged detaily. So this research's aim is current temple's situation investigation and each temple's detailed reserch 1) The construction of all temples goes back even to the Silla Dynasty. However, the arrange ment structure of then Buddhist temple was completion of the arrangement structure with the courtyard clearly now in a Chosun Dynasty. Especially, the construction time of the grand gate which the component of such an arrangement structure to be assumed the 17th century of which the middle of a Chosun Dynasty. 2) Moreover, it is a building where it was built to be paid objects is deified to these buildings are 山神(SAN SIN), 獨聖(DOK SUNG), and 七星(CHIL SUNG). Especially being paid attention is 山神(SAN SIN) belief. There was a belief to 山神(SAN SIN) from ancient times. However, coming to be deified in the temple is from a furnace in the 17th century. By the way, it was able to be confirmed to have come to be built in the temple which had been investigated by this research in the 20th century in the latter half of the 19th century.
