정진웅,박기재,정승원 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2003 한국식품저장유통학회지 Vol.10 No.3
김치 제조시 위생적 품질 개선을 위하여 ethanol과 천연항균물질인 polylysine의 복합 첨가를 검토하였다. Ethanol 농도를 0.3, 0.6 및 0.9%로 첨가하여 김치를 제조한 후 10℃에 저장하면서 3일 간격으로 총균수, 대장균군, 젖산균, 곰팡이 및 효모 등을 비교 측정한 결과, ethanol의 첨가는 대장균군과 젖산균의 생육 억제에 있어 보다 효과적인 것으로 나타났으며, ethanol 농도 0.6% 첨가시부터 미생물 생육 억제 효과가 뚜렷하게 나타났다. 또한 ethanol 0.6%를 첨가하여 담근 김치는 저장중 pH 저하 및 산도 상승에 대한 지연효과를 보여주었고, 저장중 관능특성의 변화에서도 신냄새, 이취, 신맛, 이미, 조직감 및 종합적 기호도의 모든 항목에서 가장 우수한 것으로 평가되었다. Polylysine은 단일 사용시 보다는 0.6% ethanol과 복합 첨가했을 경우 미생물 생육 억제에 상승효과를 보였으나 관능 평가에서 이미 이취를 느낀 것으로 평가되어 0.6% ethanol 단일 첨가가 미생물 증식 억제 및 발효 지연에 가장 효과적인 것으로 나타났다. Addition of ethanol and/or polylysine to kimchi ws investigated to improve its microbial hygienic quality and to extend shelf-life. Ethanol was added to kimchi with several concentrations(0.3%, 0.6%, 0.9%) and stored at 10℃. Addition of 0.6% and 0.9% ethanol showed apparent inhibitory effect on growth of microorganism, but any distinct difference was not found between those concentrations. Addition of ethanol was more effective on growth inhibition of coliform and lactic acid bacteria than other. Addition of 0.6% and 0.9% ethanol retarded apparently pH decrease and acidity increase. Although addition of 0.6% ethanol in combination with 0.12% polylysine showed good retardation of pH decrease and acidity increase, overall organoleptic quality was not good because of off-flavor and taste. Also, addition of 0.6% ethanol showed good overall organoleptic quality.

Hemolytic uremic syndrome is characterized by Coombs-negative microangiopathic hemolytic anemia, thrombocytopenia, and acute renal failure in infant and children. At present, E. coli 0157 : H7 and other verotoxin-producing E. coli(VTEC) seem to be a major cause of this illness. The majority of patients have a prodrome of bloody diarrhea, and acute renal failure develops several days to weeks later. Although an optimal treatment remains unknown, the general management of hypertention and renal failure with early and frequent dialysis is the mainatay of treatment, and intravenous administration of immunoglobulin G is like to be effective. We experienced a case composed of bloody diarrhea, seizures, coma, and anuria in 1 year old girl who was diagnosed as HUS and recovered renal function completely with slight impairment of cognitive ability and behavioral function. We presented this case with a review of literatures.

This paper deals with the rationalization of noise control in sports games-tennis, golf, shooting and archery-by examining former researches on the effect of noise to human performances. Noise as ndesirable sound has harmful effect on human body when the volume level is too high. Physiology, psychology and mentality influenced by noise stress interfere with players' performances. This paper comes to conclusion that noise detrimentally afects player's performances in sports games. However, a practical study on the intimate connection between noise and players' achievement will be required.

The research about the AMR has been progressed, which can bridge a disadvantage that a robot performs under a position unmoved. The AMR-Research constitutes skelton, path planning, AMRcontrol, sensor fusion and obstacle avoidance etc... The path planning of autonomous mobile robot use two method. One is global path planning and another is local path planning. In this paper, we study the local path planning of autonomous mobile robot move in unknown enviroment. This local path planning is based on neural network using the direction indicator rules learning. Also the system is made up of sensor system. The experimental results show that the developed direction indicator system operates properly and strongly at circumstance
쌀, 조, 수수 및 콩의 食餌가 흰쥐의 成長 및 血液性狀에 미치는 影響

쌀, 조 수수, 및 콩의 식이가 흰쥐의 성장 및 혈액 성상에 미치는 영향을 조사하기 위하여, 평균체중 180g의 Sprague-Dawley계 rat(♂) 각 5마리씩을 대조군(T_(0)), 쌀(T_(1)), 조(T_(2)), 수수(T_(3)), 콩(T_(4))급이군등 5개군으로 나누어 실온에서 6주간 사육하면서 사료섭취량, 급수량, 증체량과 6주후의 혈액상의 변화틀 조사하였다. 사료 섭취량은 대조군이 각 처리 실험군보다 높았으며 물의 급수량도 동일한 결과이었으며 그 순위는 쌀, 조, 콩, 수수 순으로 감소하였으며, 각 처리군의 증체량은 대조군 보다 낮았으며, 특히 수수는 초기보다 감소하였고, 각 처리군의 사료효율은 대조군보다 낮았으며 특히 수수처리군이 타 처리군보다 낮았다. 연액성상의 변희는 대조군에서는 큰 변화가 없으나 수수군에서 BUN, HOT지 다른군보다 높았으며 쌀의 처리군은 creatinine치가 높았고 조에서는 혈당치가 낮았으며, 콩에서는 LDH는 높았고, HGB, HCT, PI.T, RBC가 낮았고, 특히 콩 수수에서는 혈액상의 변화가 가장 컸으며 다른 실험군과 비교하였을 때 통계적인 유의성이 인정되었다. This study was conducted to investigate the effects of rice, millet, sorghum and soybean diet on the growth rate, daily intake feed ratio and change in hematology of male rats. The experimental male rats of 180g average weight were fed on control (T_(0)), rice (T_(1)), millet (T_(2)), sorghum (T_(3)) and soybean diet (T_(4)) for 6 weeks. The amount of daily feed and water intake supply in each diet group is higher than that of control group to as shown in the following order: rice, millet, soybean, sorghum. The growth ratio of each diet group is lower than that of control group. Especially, sorghum made each diet group reduce the weight even more than the initial weight. Control group is lower than each diet group in regard to the effective ratio of feed. Especially, the sorghum group is lower than other groups. Control group remained same in the change of hematology, however, sorghum group is higher than other groups for BUN, HCT. Rice group is higher in creatinine and millet group is lower in glucose content of serum than any other groups. Soybean group is higher in LDH but lower in HGB, HCT, PLT, RBC than control group. Especially, the soybean and sorghum groups showed a big change in hematology and had the statistic significance in comparison to other groups.
Herbicidal action of clove oil on cucumber seedlings
Park, Kee-Woong,Choi, Sung-Hwan,Ahn, Jae-Young,Sohn, Young-Geol,Kim, Chang-Gi,Lee, Jeung-Joo The Korean Society of Weed Science and The Turfgra 2011 Weed Biology and Management Vol.11 No.4
The herbicidal action of clove oil on cucumber seedlings was characterized under light and dark conditions. Paraquat showed herbicidal activity only under the light condition, whereas the clove oil displayed herbicidal activity in both the light and the dark condition. Specifically, wilting and water content reduction progressed rapidly under both the light and the dark condition 1 h after the clove oil treatment, whereas the paraquat damage occurred only under the light condition 5 h after treatment. The malondialdehyde concentration increased more with the clove oil treatment than with the paraquat treatment under the light and dark conditions. The superoxide dismutase (SOD) activity was stimulated, but the catalase activity decreased in the clove oil treatment. In contrast, both the SOD and catalase activity decreased in the paraquat treatment. These results suggest that clove oil exerts herbicidal effects through a mechanism that is different from that of paraquat.
