고에너지 중이온 원자핵과 핵건판의 충돌에서, 200GeV/핵자 유황이온에 의해 생성된 파쇄 헬륨핵(Z=2)의 실험실계의 방출각 분포는 표적핵에 무관한 회귀공식. dN=exp[a+k exp(η-y_b)]d[exp(η-y_b)]로 잘 표현된다. 여기에서 의사신속도 η=-ln[tan(θ/2)]이고, y_b는 실험실계의 입사입자(^32S)의 신속도이다. 이 공식에 의한 적합에서 k=-0.057±0.008로 얻어진다. 즉, 핵건판과 고에너지 중이온의 충돌에서 파쇄 헬륨핵의 exp(η-y_b)의 분포는 "극한파쇄" 현상을 잘 설명하고 있다. The angular distribution of emission angle θ of helium (Z=2) produced in the collisions of incident particles of 200 GeV/nucleon ^32S in nuclear emulsion is well expressed by dN=exp[a+k exp(η-y_b)]d[exp(η-y_b)] where the pseudorapidity is η=-ln[tan(θ/2)], the laboratory system primary rapidity is y_b, and k=-0.057+0.008. The shape of this frequency of occurrence distributions in terms of exp(η-y_b) attests to the validity of the concept of "limiting fragmentation" for helium projectile fragments produced in the projectile fragmentation regions of heavy ion collisions in nuclear emulsion.

The purpose of the experiment was carried out to determine the effects of boron application and cutting management on the growth, yield and feeding value for the purpose of practical culture and utilization techniques. The trial was performed at different borax application level(main treatments ; 0, 15, 30kg/ha) and growth stage(sub treatments : Bud, 10% bloom and 100% bloom stage) from 1989 to 1990 in experimental field college of Natural Science, Kon Kuk University. The results obtained are summarized as follows : 1. The effect of borax application in the plant length was shown, but plant length in the first and second cutting time of the first year and first cutting time of the second year after sown was high by the progression of growth. 2. There was not significant among main treatments(B??·B₁·B₂)in dry matter yield, but was shown significantly high (p<0.01, 0.05) by the progression of growth in first cutting time. 3. The content of chemical composition, NDF and ADF were not affected by boron application, and content of crude protein was decreased and those of curde fiber, NDF and ADF were increased by the progression of growht in first cutting time. 4. There was not significant among main treatments(B??·B₁·B₂) in crude protein yield but was significant (p<0.05) by the progression of growth in first cutting time. 5. There was not significant among main treatments(B??·B₁·B₂) in palatability, but palatability by growth stage was the highest at bud stage in first cutting time of first year after sown.

Y. J. KIM, J. G. JI, J. T. KIM, J. H. HONG, J. S. LEE, H. S. LEE, S. B. PARK. A comparison study for mask plantar pressure measures to the difference of shoes in 20 female. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 83-98, 2004. The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows : 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability. Considering center of force trajectory analyzing, the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.

Kim, B.-C.,Jeong, W.-J.,Kim, D. Y.,Oh, H.-W.,Kim, H.,Park, D.-S.,Park, H.-M.,Bae, K. S. Microbiology Society 2009 International journal of systematic and evolutiona Vol.59 No.5

<P>Pu'er tea is a fermented drink made from the leaves of the tea plant, Camellia sinensis. Two novel bacteria, designated strains b09i-3(T) and b13i-1, were isolated during the process of fermentation of this tea. These isolates were Gram-positive, endospore-forming, motile rods that grew at 25-42 degrees C and pH 5.5-10.4. The DNA G+C content was 56.6-58.4 mol%, the predominant isoprenoid quinone was MK-7 and the predominant cellular fatty acid was anteiso-C(15 : 0) (49.0-50 % of the total). Phylogenetic analysis based on 16S rRNA gene sequences showed that strains b09i-3(T) and b13i-1 shared 99.9 % similarity and were affiliated with a cluster within the family Paenibacillaceae. Strains b09i-3(T) and b13i-1 were related most closely to Paenibacillus ginsengihumi DCY16(T) (97 % 16S rRNA gene sequence similarity). Levels of DNA-DNA relatedness between the two novel isolates and P. ginsengihumi DCY16(T) were below 56 %. The phylogenetic and phenotypic characteristics of these novel isolates allowed them to be distinguished clearly from recognized species of the genus Paenibacillus. Based on these data, strains b09i-3(T) and b13i-1 are considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus pueri sp. nov. is proposed. The type species is b09i-3(T) (=KCTC 13223(T)=CECT 7360(T)).</P>

This study was conduct to investigate the interactive effects of sodium lactate addition and lactic acid dipping on the shelf life of Vienna sausage. Three kinds of Vienna sausages were macwfacaured as the control (addition of potassium sorbate and dipping in fumaric acid solution), treatment A(addition of sodium lactate and dipping in fumaric acid solution) and treatment B(addition of sodium lactate and dipping in lactic acid). They were divided into two groups and one group was stored at 5℃ for 6 weeks and the other one at 20℃ for 4 weeks. The physico-chemical properties of sausages were exanuned during the storage time. $quot;Ihe results are summarized as follows: 1. At both storage temperatures, lactic acid contents of treatment A and B were significantly (P$lt;0.05) higher than that of control. As storage period passed, it was significantly (P$lt;0.05) decreased in all treatments. Also, the decreasing rates of control and at 20℃ were higher than those of treatment A, B and at 5℃. 2. Jelly strength was low in the order of control, treatment A and B at both storage temperatures. Jelly strengths of control and treatment A were higher at the end of the storage compared to at the initial stage of the storage but treatment B was lower. It was lower at 30℃ than at 5℃. 3. At both storage temperatures, treatment B and control showed significantly (P$lt;0.05) higher $quot;L$quot; value than that of treatment A but lower $quot;a$quot; value, $quot;b$quot; value was decreased in the order of control, treatment A and B. $quot;L$quot; and $quot;a$quot; value were significantly (P$lt;0.05) decreased with storage period in all treatments but $quot;b$quot; value showed a increasing tendency. Treatment B showed intense discoloration compared to other treatments at 20℃. 4. In sensory panel score, there was a difference between control and treatment B and the difference was more obvious at 20℃ than at 5℃. From the results mentioned so far, it was shown that, treatment A maintained similar product quality to control at both storage temperatures white treatment B only at 5℃.

Bacillus cereus and Bacillus thuringiensis spores in Korean rice: Prevalence and toxin production as affected by production area and degree of milling

Kim, B.,Bang, J.,Kim, H.,Kim, Y.,Kim, B.s.,Beuchat, L.R.,Ryu, J.H. Academic Press 2014 FOOD MICROBIOLOGY Vol.42 No.-

We determined the prevalence of and toxin production by Bacillus cereus and Bacillus thuringiensis in Korean rice as affected by production area and degree of milling. Rough rice was collected from 64 farms in 22 agricultural areas and polished to produce brown and white rice. In total, rice samples were broadly contaminated with B. cereus spores, with no effect of production area. The prevalence and counts of B. cereus spores declined as milling progressed. Frequencies of hemolysin BL (HBL) production by isolates were significantly (P @? 0.01) reduced as milling progressed. This pattern corresponded with the presence of genes encoding the diarrheal enterotoxins. The frequency of B. cereus isolates positive for hblC, hblD, or nheB genes decreased as milling progressed. Because most B. cereus isolates from rice samples contained six enterotoxin genes, we concluded that B. cereus in rice produced in Korea is predominantly of the diarrheagenic type. The prevalence of B. thuringiensis in rice was significantly lower than that of B. cereus and not correlated with production area. All B. thuringiensis isolates were of the diarrheagenic type. This study provides information useful for predicting safety risks associated with B. cereus and B. thuringiensis in rough and processed Korean rice.
