Background: Anaphylaxis is a systematic allergic reaction, which may be fatal. However, despite its seriousness, its low level of incidence has prevented in depth studies. Thus, we analyzed the causes of anaphylactic shock in patients admitted in a tertiary hospital, observed its clinical symptoms, and formed a basis for adequate emergency treatment, as well preventive methods. Methods: The patients who visited Ajou university hospitals from June 1994 to May 2000(7 years) and who met the 1974 JAMA definition were selected for this retrospective study. The analysis of causative agents was made on the basis of clinical symptoms and the patients' chief complaints at the time of admission. Patients diagnosed with anaphylactic shock included those showing at least two types of IgE-mediated symptoms; and those with a simple rash or breathing difficulties were excluded from the study. Results: Of 36 patients, 22 were male and 14 female, Those below the age of 20 comprised 16.7% of the patients(6 patients), between 20 and 29 comprised 16.7%(6 patients), 30 and 39 comprised 25%(9 patients), 40 and 49 comprised 27.8%(10 patients), over 50 comprised 14%(5 patients). The overall percentage show 70% of the patients in active adult age group. Rash was the most common clinical symptoms(89%, 32 patients) and hypotension the second(75%, 27 patients), followed by respiratory distress, fainting, and arrhythmia. Causative agents were insect bites, including bee stings(15 patients), medication(12 patients), food(8 patients), and unknown(1 patients). Nine(9) of the 36 case, were diagnosed as having an atopic origin. Conclusion: Bee sting was the single most common cause in the insect criteria while penicillin & NSAIDs accounted for most of medication-induced cases. Food showed a varied distribution. An atopic origin was not a basis for anaphylactic shock, but did show a two-fold increase of prevalence. This study is the first of its kind in addressing anaphylactic shock, a potentially severe illness, over a period of 7 years.

To investigate the effects of short-term weight reduction and subsequent rehydration on performance of the judo players, eight college-age judo players performed cybex and 3 wingate tests, seperated by 45min or 1 hr, before and after weight reduction(5%). Muscle strength, anaerobic power, anaerobic capacity, blood lactate, and blood pH level were measured. The results were as follows: 1. There were no differences in muscle strength and total work capacity, measured by cybex, between pre and post weight reduction. 2. There were no differences in peak power and anaerobic capacity, measured by wingate test, between pre and post weight reduction. It was concluded that 5% weight reduction followed by 4 hours of food consumption did not decreased the physical capacity measured by multiple wingate tests.

Digitizing of model parts is the main step in reverse engineering. Presented in the paper is a step-by-step procedure for generating NC toolpaths from optically digitized data, or "cloud of points" data in industrial parlance, which is generated by commercial laser scanning machines of a specific type. The main problem in generating NC toolpaths from cloud of points data is to obtain a smooth fairing of random measurement errors at the presence of missing data points. The most challenging task is reconstructing transition surface features which are usually damaged by random errors and missing points. The procedure for generating NC toolpaths from digitized data consists of five major steps: meshing, splitting, surface fairing, Z-map sampling, and toolpath generation. The proposed method for NC toolpath generation has been applied to a few test cases with premising results.

In this study, for application of FEM in a practical way, a systematic method is proposed to model bolted joints by using member stiffness. First, stress analysis is performed to find angle of stretch with respect to joint force variation. Then using this result, member stiffness is calculated and used to model joint part as spring. Two kinds of dynamic analysis is performed, one is pure model which have solid and thin shell element neglecting joint force variation, and the other is spring model according to joint force variation. Analysis result shows that natural frequency of pure model is 2.4%-4.8% lower than spring model, it is also fecund that natural frequency is proportioned to joint force increasing.

Recently, there have been much corncerns about the strategies which can reasonably increase farm income at the average farm level. In other words, as a result of third-term Five Year Economic Development Plan there was a remarkable gap between farm household and non-farm household incomes. Therefore, various policy tasks to eliminate this unbalanced income growth are currently being implemented. This study was carried out to identify the situation of livestock farming at general farm level, regarded as one of income generation strategies for the farm sector. Some results of the study can be summarized as follows: First of all, it was found that a group of farms which raise a small size of animals like Korean cattle, hog, and various poultry gave higher resource bases as compared with that of non-livestock farms. Secondly, it was also recognized that both farm and farm household income levels of small-scale livestock farms were higher than those of non-livestock farm group within the same region, specifically as much as approximately ￦200,000. Thirdly, it was known that the average size of animal raising per household in 0.9 head of cattle, 0.8 head of hog, and 34 lyers of poultry, respectively. To the end, according to the farm disposal practices of major by-products, only about 18 percent of total rice straws produced at individual farms was utilized for the animal raising, and about 45 percent of all the brans available at farms for the livestock enterprise. The rest of straw and brans in regarded as selling at farm level. In this respect, it may be recommended either to increase current size of animals or to expand number of livestock farms.

Characteristics of an L-band transmitter and a receiver are examined which can be used for real time image transmission from micro-aerial vehicle(MAV) and/or autonomous vehicle system to the ground station. Transmitter power is sub-50 mWatts and uses 970 MHz carrier frequency for frequency modulation (FM) of real time NTSC image signal. Antenna shows pseudo-omnidirectional radiation pattern and excellent impedance matching characteristics at the operating frequency. Real time image transmission/ reception and image data compression using mpeg encoder are performed with notebook PC from a moving vehicle, which results in very encouraging image quality applicable to surveillance and observation using MAV.
