  • To know proper drying condition for making a safe Sunsik, uncooked food, microbial and physicochemical characteristics of cereal dried by hot-air drying was investigated. As moisture content of 3 Sunsik samples was reduced to about 8%, protein, carbohydrate, fat and ash content of those was increased. But approximate composition of black bean, black rice and glutinous millete and black bean showed little changes during hot-air drying (30, 40, $50^{\circ}C$). Lightness (L value), redness (a value) and yellowness (b value) was increased after hot-air drying. In case of black rice and glutinous millet, b value and L value wasn't changed individually. When we measured a texture for 3 kinds of raw cereal for, hardness of dried cereals was lower than raw cereals. Hardness of dried cereals was increasd as drying temperature was increased. As results of mocrobiologicl experiment for 3 kinds of sunsik on hot-air drying conditions, total cell count was reduced 2 log - 3 log and other pathogenic microorganism wasn't detected except B. cereus.

  • This study is aimed to test physiological and hematological actions of Rheum palmatum through clinical pilot study optimized for usual oriental medicine prescription. Thirty-one cases were finally collected and the sample extract 100 $m{\ell}$ of Rheum palmatum (ERP) was administered two times in a day during 3 days and checked with blood CBC test, urinalysis, liver function test, abdominal X-ray as well as general diagnostic process of oriental medicine; pattern identification, assessment of shapes and constitution. The total toxic effective rate of ERP was 9.68% in 3 cases of the whole in case of consistent uneasy state in the subjective symptomatic assessment and aggravation of blood and urine examination. The relevant diagnostic factors were so-eum constitution and essence type subject, carapaces species, lung type in the aspect of Jisan shape theory. On the other hand, the positive effective rate of ERP was 29.03% manifesting improvement of vital signs or present illness and no abnormal changes of blood chemistry and urinalysis and simple abdomen radiology. The relevant diagnostic factors were tae-eum constitution, energy type subject, aves species, heart and liver type in Jisan's shape theory. And the other cases were manifesting no specific change through the administration of ERP. The ratio of the numbers of decrease and increase was 44:5 in the tenderness and hardness of abdominal palpation. But if the pattern identification doesn't comply with the aim of rhubarb application despite of constipation and abdominal pain, the tendeness and biochemical report was shown in abnormal change. The mean number of diarrhea by ERP was $16.77{\pm}6.95$ during 3 days after administration, and the frequent areas of abdominal pain were lower>middle>upper in order, and it meant the target site of ERP too. Besides, the toxic reaction against ERP was expressed highly in case of decrease in blood cell count and hemoglobin, hematocrit having blood deficiency syndrome. Likewise, the toxicity of ERP was influenced by pattern identification manifesting present disease condition and diagnostic factors of four constitutions, Jisan's shape theory collaterally. In conclusion, evaluation of herbal toxicity in order for using as a clinical guideline, various diagnostic pattern information and shape features like the above should be studied together with other pharmacologic toxicology test for the future.

  • The environment and biological studies of tritium have been carried out in the advanced countries since the mid 1950's. In the case of a potential tritium exposure, the usual procedure is trifium bioassay (as HTO) in human urine in order to determine the amount of tritium deposited in the body called tritium body burden. The maximum permissible body burden(MPBB) of tritium in total body is about $30{\mu}Ci/{\ell}$ for body tissue. In the bioassay, the most common investigation level for detection of tritium in urine is 1/10th of MPBB. For this bioassay project, the first priority is given to obtaining a quench correction curve. This consideration is necessary because of the variability in color of human urine specimens. Quenching effect in this case mainly is caused by the absorption of scintillation light flashes by the urine sample. By the least squares method on the statistical basis, an estimated formula for quench correction curve was determined to be Y = 0.771 + 1.836 ${\tmes}10^{-4}$X, where the efficiency(Y) was ranged from about 12% to 31% in the liquid scientillation counting. In this paper, a brief theory concerning the biological half-life of tritium and the retention formula to apply to systematically distributed tritium are described.

  • Lab effectively supplemented the effects of outside radiation on image plates in the process of image acquisition of CR (computed radiography) systems and conducted for effective utilization in the case of clinical application. For this, Lab classified the storage places and time periods of image plates and compared and analyzed the differences between small dark spots. Lab also assessed the concentration distribution within the boundaries of images. Lab compared and measured the number of dark spots in a light room and a dark room depending on the storage places of image plates and found that dark spots slightly increased in an image plate when stored in a light room on the first and second days. Dark spots increased in proportion to the length of time stored. In the case of the image plate stored in a dark room, the number of dark spots remarkably decreased. With regard to picture quality as related to the location of image plates, the damage to picture quality could be reduced by locating regions of interest in the center. With regard to differences in sharpness following changes in the thickness of subjects, fewer scatter rays occurred and sharpness improved by reducing the thickness of subjects as much as possible. To get medical images of excellent quality, image plates should be managed effectively and it is desirable to keep images plates in dark iron plate boxes and not to expose them to outside radiation for a long time.

  • Bilateral convergent strabismus with exophthalmus(BCSE) is an eye disorder affecting many cattle breeds worldwide. BCSE is the most common in cattle at various types of strabismus. Divergent strabismus is of relatively low incidence than convergent strabismus. This report is the to shown a case of convergent and divergent strabismus with unilateral in the exophthalmus in a heifer Holstein cow. A female Holstein calf born with congenital progressive divergent strabismus in right eye and convergent strabismus in left eye was tested. Ocular and blood examination, and activity were checked from the first week, 8 month, and 16 month after birth. The ocular examination includes general inspection, fixation reflex and menace response. The general inspection is checking the degree of deviation of both eyes from the normal visual axis, which was determined by the amount of sclera permanently visible in the temporal corner of the eye. The stage is divided into 4 stages depending on the degree of deviation. The right eye shown in stage 4 continues after birth and the left eye shown stage 2, stage 3 and stage 4 at 1 week, 8 month and 16 month after birth, respectively. In fixation reflex and Menace response, both eye balls showed a normal response at 1 week, 8 month and 16 month after birth. Blood count and serum chemistry test were performed, but a specific factor was not detected outside the reference range.

  • This study is to evaluate the characteristics of SCC at the welded region of high strength steel using acoustic emission(AE) method. Specimens were loaded by a slow strain rate method in synthetic seawater and the damage process was monitored simultaneously by AE method. Corrosive environment was controlled using the potentiostat, in which -0.8V and -1.1V were applied to the specimens. In the case of one-pass weldment subjected to -0.8V, much more AE counts were detected compared with the PWHT specimen. It was verified through the cumulative counts that coalescence of micro cracks and cracks for the one pass weldment with -0.8V were mostly detected. In case of the one pass weldment subjected to -1.1V, time to failure became shorter and AE counts were produced considerably as compared with that of the two pass weldment. It was shown that AE counts and range of AE amplitude have close relations with the number and size as well as width of the cracks which were formed during the SCC.

  • The aim of this study was to evaluate the microbial safety and quality changes of Korean sliced pork jerky, and to investigate these properties over 90 days and 28 days of storage at room temperature $(25^{\circ}C)$ and elevated temperature $(35^{\circ}C)$. Based on the microbial counts of pork jerky, mesophilic bacteria were detected at 2.50 log CFU/g at day 0. The mesophilic bacterial count did not change significantly for all samples, and coliform bacteria and Bacillus cereus were not detected in any samples during storage at either $25^{\circ}C\;or\;35^{\circ}C$. The following physicochemical qualities were also investigated: TBA value, Aw, and pH. In the case of $25^{\circ}C$ storage, the Aw of Korean sliced pork jerky was 0.72 at day 0, and was reduced to 0.58 after 90 days of storage. The TBA value increased as the storage time increased, and was 0.52 after 90 days of storage. The pH of all samples did not change significantly. In the case of $35^{\circ}C$ storage, the TBA, Aw, and pH values were not significantly different from those obtained during $25^{\circ}C$ storage. In addition, the sensory properties of all samples were not significantly different between storage at the two temperatures. In conclusion, these results suggest Korean sliced pork jerky could be used to study the development of commercial pork jerky.
