This study was performed to develop Korean products of culture medium which favors the growth of the enteric bacteria and others. The essential nutrients was made from the extract of a oyster (Ostrea gigas). The new plating Oyester agar medium was tested for the growth of the members of the Enterobacteriaceae and Vibrionaceae and their ability to from colonies with nutrient agar medium. The following results were obtained. 1. Oyster agar medium was better than nutrient agar medium for the growth and isolation of all the members of the Enterobacteriaceae. The Salmonella enteritidis and E. coli formed large colonies especially on the oyster agar plate. 2. Oyster agar plate was the best media for the isolation and selection of Pseudomonas aeruginosa. 3. Most of the Vibrionaceae were inhibited on Oyster agar media and Staphylococcus aureus were highly inhibited.

This paper describes the development of sputtered tungsten electrode for discharge tube by making use of Sputtering method using plasma. The Xe discharge tube was designed and fabricated by using sputtered tungsten electrode, and the ICCD(Intensified Charged Coupled Device) and monochromator were used in order to observe the discharge image distribution and to measure the signal intensity. As a result, the emission light form the electrode was spreaded almost uniformly over a wide wavelength band, and the discharge image distribution and the signal intensity show quite a uniform distribution. The emission light from the Xe discharge tube was peaked at 488[nm] and 648[nm].

Disaster is a any community or regional events that disrupts community functions and activities and cause concern for the lives, health, and property of the citizens of that community. Successful management of disaster requires adequate planning and practice drills. Emergency medical service must play an important role in disaster management because any disaster produces various types of patients who need emergent care. We tried to analyse korean disaster planning in review of three recent disasters including aircraft crash, ship submergence, and road traffic accident. The result of disaster survey shows that there are many defects in Korean disaster plan at the stage of notification, propagation, rescue, stabilization and withdrwal and emergency medical service system is not being involved in disaster management because korean disaster plan is a civil-defence model. We conclude that current korean disaster plan is inadequate for management of disaster and it should be reinforced.

For the navigation of an autonomous mobile robot in complex environment, the map building of the environment is needed using sensors. The ultrasonic sensor is low cost, easy to install and has high-speed information processing persormance. Environment recognition using ultrasonic sensors, however, has two major problems: the uncertainty information of sensor and false readings caused by specular reflection and multipath effect. In order to resolve these problems, an map building method using Bayesian update model was proposed previously[5]. In this paper, we present an improved method of probability map building that uses infrared sonsors and shift division Gaussian probability distribution with the existed Bayesian update model using ultrasonic sensors. The validity and the persormance of the improved map building method are examined by simulation and experiment with real mobile robot.

Abstract The purpose of this study is to emphasize the importance of chartering decision in the shipping firms. In fact, skipping industry does the business in a completely open market between shipping firms and cargo owners all over the wolrd. This connection, the level of risk on the business managent of shipping firm is relatively high compared with other industries. In particular, the decision on the ship purchase, ship building and ship chartering is very important element to decide the future of the company. Accordingly, this paper will study the essential elements which will effect to the decision of the ship chartering and the basic reasons why shipping firms make the decisions of ship chartering with the burden of high risk management. According to the above results of the study, shipping firms make chatering decisions even though they are on the high level of risk in order to improve cash flow and profit of the company. Furthermore, the shipping firms operating ships efficiently and positively run into chartering market with high level of risk on chartering decision. It shows a shipping firm has no particular option except the derision of chartering in order to survive and grow up continuously under unlimited competition in the world-wide open market.

The posttraumatic cubitus varus and valgus deformity is generally caused by malunion of supracondylar and condylar fracture of humerus in growing children. Generally it is known that carrying angle change is benign deformity causing no specific functional disabilities and the correction of the carrying angle change is performed for cosmetic reason. But after corrective osteotomy, there remained some Lasy S deformity on elbow joint. We invesgated the cause of this Lasy S deformity and found that most of deformity is caused by improper osteotomy, but we also found there developed some bowing deformity of the proximal ulnar metaphysic. So we measure the proximal ulnar bowing of 12 cases of cubitus varus and 4 cases of cubitus valgus which were operated on from 1984 to 1994. We also study the correlation between the amount and duration of the carrying angle change which the amount of the proximal ulnar bowing. The amount of carrying angle and carrying angle change correlate with the change of proximal ulnar bowing significantly. There is some correlation with duration of carrying angle change from proximal ulnar bowing.

This study was designed to research the clinical efficacy and tolerance of Diclofenac sodium, a potent inhibitor of prosta-glandin synthetase. Total 53 cases of painful condition in orthopaedic field were treated with Diclofenac sodium, available for intramuscular injection, in department of orthopaedic surgery of Chungnam National University Hospital from Nov. , 1986 to Jan. , 1987. Among 53 cases of painful condition, The most common condition was rheumatoid arthritis and osteoarthritis (33cases; 60. 3%), followed by sprain and strain(llcases; 20. 8%), postoperative state(7cases; 13.2%), and others(3cases 5.7%). There was no predilection in age and sex distribution. At thirty minutes after the injection, 46/53patients treated with Diclofenac sodium had complete 31(58.5%) or partial 15(28..3%) relief of pain. Side effects were mild and transient. It is concluded that intramuscular injection of Diclofenac sodium is effective in treatment of pain due to operative intervention & various disease in orthopaedic field.

The vertical distribution of the canopy trees in Mt.Bukhan was studied by quedrat method. In this mountain, there were distributed about 126 species of main trees and forest communities consist of Quercus mongolica, pinus densiflora, Alnus hirsuta var. sibirica, Acer pseudo-sieboldianum var. koreanum, Sorbus alnifolia, Quercus acutissima and so on. The change of forest communities according to the elevation of this mountain was not conspicious. As The elevation heightened of this mountain, the importance value and summed dominance ratio of Fraxinus rhynchophlla and Acer pseudo-sieboldianum var. koreanum increased, while those of Quercus variabilis lowered. Through all the area of this mountain, mean importance value of Quercus mongolica was high. There appeared difference type of vegetation between valley and ridge area but no directional recognize in the kind of plant species though very few species were limited in a limitted part, such as Celtis aurantica of the ridge area, and Quercus acutissima x variabilis of Jeongnung valley. In each study area, Pinus densiflora on the floor was abundant and the summed dominance ratio of Sorbus alnifolia, Quercus serrata and Quercus aliena were high to elevation range for 250-350m. As the elevation hghtened, the mean of total base value of soil samples in study area was high but the mean of O,M. and available phosphate value of those did not show a fixed tendency. The relationship of the importance value of Fraxinus rhynchophylla and the mean of total base value of soil in study area showed a significant and positive correlation. The index of similarity of the forest communities to the valley and ridge area, and to the southeast and northwest side of Mt.Bukhan were 63.7, 67.7% respectively.
