To share knowledge efficiently among our members on the basis of knowledge management system, first of all, we need to systematically design the knowledge classification scheme that we can classify these knowledge well. The objective of this study is to construct the most suitable knowledge classification scheme that all of us can share them in Korea Atomic Energy Research Institute (KAERI). To construct the knowledge classification scheme all over the our organization, we established a few principles to design it and examined related many classification schemes. And I carried out 3 steps to complete the best desirable KAERI's knowledge classification scheme, that is, (1) the step to design a draft of the knowledge classification scheme, (2) the step to revise a draft of the knowledge classification scheme, (3) the step to verify the revised scheme and to decide its scheme. The scheme completed as a results of this study is consisted of total 218 items : sections of 8 items, classes of 43 items and sub-classes of 167 items. I expect that the knowledge classification scheme designed as the results of this study can be played an important role as the frame to efficiently share knowledge among our members when we introduce knowledge management system in our organization. In addition, I expect that steps to design its scheme as well as this scheme itself can be applied when design a knowledge classification scheme at the other R&D institutes and enterprises.
This test has been carried out to evaluate the effect of temperature on the growth of the insecticide susceptible strain, URY-O nomal genotype and insecticide resistant strain, O-RT abnormal genotype, and ABURABI nomal genotype. The nymphal periods were not significantly different between URY-O and O-RY strains at $25^{\circ}C$. At $30^{\circ}C$, susceptible strain URY-O could give birth to offsprings almost nomally, while resistant strain O-RY could not produce any offspring for 20 days which results in nymphal death. The numbers of offsprings of strain URY-O and strain ABURABI were not different between $25^{\circ}C\;and\;28^{\circ}C$, but strain O-RY, when it was reared at $28^{\circ}C$, could produce offsprings only 10% of those at $25^{\circ}C$. Body weight of strain URY-O and strain ABURABI were 0.22mg/female and 0.27mg/female, respectively at $28^{\circ}C$, however that of O-RY was only 0.16mg/female, showing considerable difference between normal and abnormal genotype. Substrain O-RY(+) which has high esterase activity showed poor reproduction ability(0.8 progenies per $G_{1}$ individual than substrain O-RY(-) (3.4 progenies per $G_{1}$ individual) which has low esterase activity at $28^{\circ}C$
Effect of puffing treatment on saponins, total sugars, acidic polysaccharide, phenolic compounds, microstructure and pepsin digestibility of dried red ginseng tail root were tested. Puffing samples of dried red ginsneng tail root were pre-pared at 20rpm, 15 $kg/cm^2$, $120{\sim}150^{\circ}C$, and for 30 min by a rotary type apparatus of 5 L capacity. Crude saponin content of puffing red ginseng tail root was increased 26.5% compared to non-puffing, especially $Rg_3$ content was increased from 0.49 mg/g to 0.72 mg/g. Total sugar content was not changed, but acidic polysaccharide content was slightly decreased from 7.15% to 6.44% by puffing treatment. Total phenolic compounds was increased from 7.86% to 9.94% by puffing. In terms of individual phenolic compounds, salicylic acid was quantified in puffing tail root, but gentisic acid was quantified in non-puffing. Syringic acid was the most predominant phenolic acid, increased to about 6 times by puffing treatment. On the other hand, gallic acid, p-coumaric acid, caffeic acid and ferulic acid were highly decreased. Microstructure of cross-section in puffing tail root was shown to more uniform shape compared to non-puffing. Pepsin digestibilities of puffing and non puffing red ginseng tail root were 22.4% and 46.2%, respectively (p<0.05). The results indicated that puffing treatment might be useful increasing the bioactive components, preference and digestibility.
The purpose of this study was to examine the effect of various exercise intensity on Resting Metabolic Rate (RMR), excess post exercise energy expenditure (EPEE), and thyroid hormonal changes in trained (TR) and untrained (UT) people. The subject of the present study were divided into two groups and four periods: trained (TR; n=6) and untrained (UT; n=6) group. And the periods were divided as follows; Resting (R), Maximal (M), High intensity (H), and Low intensity (L). The percent body fat and RMR of all subjects were measured at every periods. The RMR was measured early in the morning following a 12-hour fast using MMX3B gas analyzer and blood sample were collected from the anticubital vein to investigate thyroid hormonal (T3, T4, Free T3, Free T4, & TSH) changes. All the RMR values were expressed as absolute value/BSA $(kcal/d/m^2)$. And We also analyzed mean energy expenditure for 30 minutes during and after different intensity exercise. There was significant difference in RMR among different intensity of exercise. in TR (p < .05) not in the UT group. however, there was no significant different percent body fat in TR and in UT group. In the energy expenditure, there was significant different between TR and UT in HEE (high intensity exercise energy expenditure), LEE (low intensity exercise energy expenditure), HEEPE (high intensity exercise energy expenditure post exercise) & LEEPE (low intensity exercise expenditure post exercise). In the hormonal level, there was significant different in T4 level in the TR group at H period and in T4, Free T3, & Free T4 levels in TR group at L period, however there was no significant different in the UT group. The present cross-sectional study was design to investigate the relationship between exercise intensity and RMR. The focus of this investigation was to compare RMR in aerobically trained (TR) and untrained (VI). The relationship among RMR, exercise intensity and percent body fat would best be investigated using MMX3B and body composition analyzer. Each subject completed measurement of percent body fat, RMR, hormone in the period of maximal oxygen uptake exercise (M), high intensity exercise (H), and low intensity exercise (L). From the results, Low intensity of exercise (L), there was a trend for an increased RMR (kcal/day) in the TR not for the UT. This is best explained not by the reduced percent body fat but by the highly induced energy expenditure (during exercise and post exercise energy expenditure) and increased T4, Free T3, and Free T4 hormonal levels in the low intensity exercise for the TR group.
Food-dependent exercise-induced anaphylaxis (FDEIA) is a distinct form of food allergy induced by physical exercise. It is typified by the onset of anaphylaxis during exercise, which is preceded by the ingestion of causal food allergens. Diagnosis of FDEIA is heavily dependent on clinical history. To describe the physiopathological mechanism, etiologic factors, and clinical manifestations, we evaluated the spleen index, proliferation assay of lymphocyte, ROS, ASAS, and cytokines levels in sensitized and exercise-trained mice. One-hundred mice were bred in the animal lab at D and P university under controlled conditions [$22{\pm}2^{\circ}C$, RH 45-55%, and a 12-hour photoperiod]. Animals are 7-weeks-old at the time of study and were fed a standard commercial chow diet from 09:00 to 15:00 over the 8-week study period. The mice were allowed access to distilled deionized water ad libitum. Daily food intake and weekly body gains were routinely recorded throughout the experimental period using computing scale (CAS). Mice were divided into the control group (S; control sensitized, n=25), 30 min swim training group (S30, N=25), 50 min swim training group (S50, N=25), and 80 min swim training group (S80, N=25). The results were as follows: Spleen index showed the highest level in the S80 group compared to other groups; this level was exercise-dependent. In proliferation assay of Med and OVA, the S80 group showed the highest level compared to the other groups; this level also was exercise intensity- dependent. Peritoneal ROS and IL-4 showed a statistically significant difference compared to S; however, there was no significant differences in ROS among S30, 50, and 80. From the results, we concluded that FDEIA is correlated with exercise intensity based on the levels of peritoneal ROS and cytokine profiles.
Purpose : The purpose of this study was to reduce Entrance Surface Dose and maintain image quality by changing Source to Image receptor Distance. And we'd like to compare ESD on this study to DRLs in other contries. Materials and Methods : We used indirect DR system(Definium 8000, General Electric, USA)and phantom(ART-200X, Flukebiomedical, USA),glass dosimeters(GD-352M, Asahi Techno Glass, Japan)for this study. The imagies were obtained throuh 80kVp fixed, and different tube currents using AEC mode in $16{\times}16$(inch) field size and changing Source to Image receptor Distance from 100 cm to 130 cm per 10 cm unit. The phantom with attaching 5 glass dosimeters on abdomonal skin was set at supine and erect position as a anterioposterial projection on detector For measuring Entrance Surface Dose. Image analysis was conducted by histograms of Image J(1.46r) which was given from National Institutes of Health(NIH). Results : Due to inverse square law of distance, the tube currents were increasing 42.6 % in supine position and 32.6 % in erect position according to the change of Source to Image receptor Distance. While Entrance Surface Doses were rapidly decreasing 14.2 % in supine position and 29.4 % in erect position according to the change of Source to Image receptor Distance. As the results of histogram using Image J, pixel mean values from 100 cm to 110 cm, 120 cm and 130 cm were decreasing each 1.4%, 2.5%, 2.7%, 4.5%, 2.2 %, 5.8 % in supine, erect position. While standard deviations from 100 cm to 110 cm, 120 cm and 130 cm were increasing each 1.4 %, 2.5 %, 2.5 %, 4.0 %, 2.0 %, 4.9 % Consequently, there are no significant differences in abdomen images taken. Conclusion: As the results described above, we strongly recommend using long Sourceto Image receptor Distance than 100cm that we have been using. So, we should deliver less Entrance Surface Dose to the patients while maintaining image quality in abdomen radiography.

The objective of this study was to determinate the effect of food waste with probiotic supplemented diets on growth performance and body composition in broiler chicks. One hundred ninety six (Ross 1 day old) broiler chicks were randomly allotted to seven treatments and raised in barely cages. As the results of the experiment the body weight gain was increased significantly in groups fed control+antibiotics supplemented diets (P<0.05), but there were no significant difference in weight gain of the chicks fed diets containing food waste with probiotic and antibiotic supplementations (P>0.05). The feed intake was increased significantly in group fed a diet containing food waste 1.5% with 0.5% probiotic supplementation but it was no significantly different for rest experimental groups (P>0.05). The feed efficiency was reduced significantly in broilers fed food waste with probiotic diets compared to groups fed control and antibiotic supplemented diets (P>0.05). The large intestine weight was increased significantly in broilers fed antibiotic supplemented diet compared to control (P<0.05). The abdominal fat was increased in groups fed diet containing food waste supplementation (P<0.05). The rest of vital organs weights was not affected by additon of food waste and probiotic supplementation in broiler diet (P>0.05).
Meat model emulsions ware prepared with salt-soluble protein and soybean oil. Effects of water-soluble protein (WSP) on the meat model emulsion treated with/without BHT during 8 day storage $5^{\circ}C$ under both dark and light illumination were studied by measuring POV and TBA. An emulsion without BHA and WSP was used as a control. Under light storage, there was no significant difference in peroxide values between the control and the sample treated with BHA except the 2nd day of storage. However, TBA values of the sample treated with BHA were significantly (p<0.05) lower than those of control except the 4th day of storage. TBA and POV of the samples treated with WSP and WSP + BHA were higher than control after 4th day of storage under light. That is, water soluble protein, which was composed mainly of myoglobin, increased lipid oxidation under light storage. The similar trends were also shown in the samples stored under dark. These results suggested that acceleration of lipid oxidation of the meat model emulsions by water soluble protein (WSP) under both light and dark might not be due to the singlet oxygen formation, but due to superoxide anion formed.

The search for patinum (II)-based compounds with improved therapeutic properties was prompted to design and synthesize a new family of water-soluble, third generation cis-diamminedichlorplatinum (II) complexes linked to uracil and uridine. Six heretofore undescribed uracil and uridine-platinum (II) complexes are ; [N-(2-aminoethyl)uracil-5-carboxamide]dichloroplatinum (II)(3a), [N-2(2-aminoethyl)uracil-6-carboxmide]dichloroplatinum (II) (3b),[5-(2-aminorthyl)carbamoyl-2',3',5',-tri-O-acetyluridine] dichloroplatinum (II) (6b), [5-(2-aminoethyl)-carbamoyl]-2',3',5',-tri-O-acetyluridine] dichloroplatinum (II) (6b), [5-(2-aminoethyl)carbamoylu-ridine]dihloroplatinum (II) (7a), [6-(2-aminoethyl)carbamoyluridine]dichloroplatinum (II) (7b). These analogues were prepared from the key starting materials, 5-carboxyuracil (1a) and 6-carboxyuracil (1b) which were reacted with ethylenediamine to afford the respective N-(2-aminoethyl)uracil-5-carboxmide (2a) land N-(2-aminoethyl)uracil-6-carboxamide (2b). The cisplatin complexes 3a and 3b were obtained through the reaction of the respective 2a and 2b ficiently introduced on the .betha.-D-ribose ring via a Vorbruggen-type nucleoside coupling procedure with hexamethyldisilazane, trimethylchlorosilane and stannicchloride under anhydrous acetonitfile to yield the sterospecific .betha.-anomeric 5-carboxy-2',3',5'-tri-O-acetyluridine (4a) and 6-carboxy-2',3',5'-tri-O-acetyluridine (4b), respective 5-(2-aminoethyl)carbamoyl-2',3',5'-tri-O-acetyluridine (5a) and 6-(2-aminoethyl)carbamoyl-2',3',5'-tri-O-acetyluridine (5b). The diamino-uridines 5a and 5b were reacted with potassium tetrachloroplatinate (II) to give the novel nucleoside complexes, 6a and 6b respectively which were deacetylated into the free nucleosides, 7a and 7b by the treatment with CH/sub 3/ONa. The antitumor activities were evaluated against three cell lines (K-562, FM-3A and P-388).

Background: Multidrug-resistant tuberculosis (MDR-TB) is an increasing public health problem and poses a serious threat to global TB control. Fluoroquinolone (FQ) and aminoglycoside (AG) are essential anti-TB drugs for MDR-TB treatment. REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$ (M&D, Wonju, Korea) were evaluated for rapid detection of FQ and kanamycin (KM) resistance in MDR-TB clinical isolates. Methods: M. tuberculosis (n=67) were isolated and cultured from the sputum samples of MDR-TB patients for extracting DNA of the bacilli. Mutations in genes, gyrA and rrs, that have been known to be associated with resistance to FQ and KM were analyzed using both REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$, respectively. The isolates were also utilized for a conventional phenotypic drug susceptibility test (DST) as the gold standard of FQ and KM resistance. The molecular and phenotypic DST results were compared. Results: Sensitivity and specificity of REBA MTB-FQ$^{(R)}$ were 77 and 100%, respectively. Positive predictive value and negative predictive value of the assay were 100 and 95%, respectively, for FQ resistance. Sensitivity, specificity, positive predictive value and negative predictive value of REBA MTB-KM$^{(R)}$ for detecting KM resistance were 66%, 94%, 70%, and 95%, respectively. Conclusion: REBA MTB-FQ$^{(R)}$ and REBA MTB-KM$^{(R)}$ evaluated in this study showed excellent specificities as 100 and 94%, respectively. However, sensitivities of the assays were low. It is essential to increase sensitivity of the rapid drug resistance assays for appropriate MDR-TB treatment, suggesting further investigation to detect new or other mutation sites of the associated genes in M. tuberculosis is required.
