The purpose of this study was investigate the effect of aerobic exercise on high sensitivity C-reactive protein(hs=CRP), inflammatory markers, and cardiovascular risk factors in obese women. Nineteen obese women(body mass indexs≥25) aged 40 to 53 years were randomly assigned to either a training or control group. The training program consisted of 12 weeks of supervised aerobic exercise(60%VO2R, 60min) three times a week on treadmill. Body weight, BMI, percent of body fat, and waist circumference were significantly decreased after training. Aerobic exercise significantly decreased cardiovascular risk factors and inflammatory markers, including fibrinogen, leptin and IL-6 whereas CRP and adiponectin did not change. The reduction of weight after training was positively associated with the decrease of SBP, TC, TC/HDL-C, TG, CRP, leptin, and IL-6. The change of CRP was positively associated with that of fibrinogen and leptin(p<.05), and also a positive correlation between the changes of leptin and IL-6 was observed(p<.01). As a results, a 12-week aerobic exercise intervention improved cardiovascular risk factors as well as inflammatory markers including fibrinogen, IL-6 and leptin, but had no effect on the modification of CRP despite the improvement of body composition in obese women.

Growth of Russian spring-summer encephalitis virus in established line of mosquito (Sigh's Aedes albopictus) cells was studied by infectivity ' titration of mouse lethal doses and observation of morphological changes on the infected cell monolayers. The cell line could support the multiplication of Russian spring summer encephalitis virus. The maximum virus titer of 10''0 mice LD50 was reached in 3 days after virus inoculation. Cytopathic effect was found on the whole monolayer from second post infective day and large round spherical cell aggregates were observed theereafter.

A successful on-line monitoring system for conventional machining operations has the potential to reduce cost, guarantee consistency of product quality, improve productivity and provide a safer environment for the operator. In fine-shape machining, typical signs of tool problems such as vibration, noise, chip flow characteristics and visual signs are almost unnoticeable without the use of special equipment. These characteristics increase the importance of automatic monitoring in fine-shape machining; however, sensing and interpretation of signals are more complex. In addition, the shafts of the micro-tools break before the typical extensive cutting edge of the tool gets damaged. In this study, the existence of a relationship between the characteristics of the cutting force and tool usage was investigated, and tool breakage detection algorithm was developed and the following results are obtained. In data analysis, didn't use a relative error compare which mainly used in established experiment and investigated tool breakage detection algorithm in time domain which can detect AE and cutting force signals more effective and accurate.

In this study, piezoelectric composites with 1-3-0 connectivity have been studied. A piezoelectric ceramic PZT prepared by the Wet-Dry Combination method is used as a filler phase in mixture of the third filler phase and Eccogel polymer matrix. The density and stiffness of 1-3-0 type composites were decreased with increasing the third phase.

쑥 분말 사료를 암돼지 및 거세돈에 첨가하여 그 수준에 따라 0%(T1, 암돼지, T2; 거세돈)와 1.5%(T3; 암돼지, T4, 거세돈)로 각 구별 45두씩 배치, 42일간 급여하여 생산된 돈육의 육질특성은 다음과 같다. 도체중량과 등지방두께는 73가 가장 낮았으며, 도체등급에서는 처리구간 유의차가 없었다(P>0.05). 쑥 분말 급여시 암돼지간(T1과 T3)에서는 조회분, 거세돈간(T2와 T4)에는 조지방 및 조회분 함량이 유의적으로 증가하였다(P<0.05). pH는 저장기간에 증가함에 따라 모든 처리구에서 감소하였으며, 쑥 분말 급여 처리구(T3와 T4)에서다소 높은 pH값을 나타내었다 드립감량은 처리구간에 일정한㎏/㎠경향을 나타내지 않았지만 저장기간이 경과함에 따라 높아졌다. 전단가(shear force, ㎏/㎠)는 T1을 제외한 모든 처리구에서 저장기간이 길어짐에 따라 감소하였다. 명도와 적색도는T3가 T1 보다 다소 높은 수치를 보였으나, 거세돈간(T2와 T4)에서는 오히려 낫게 나타났다. 저장기간이 증가함에 따라 TBARS와 VBN값은 공히 유의적으로 증가하였으며(P<0.05),쑥 분말 급여 처리구(T3 및 T4)에서 유의적으로 더 높게 나타났다(P<0.05). 지방산 분석결과, 포화지방산(saturated fatty acids)은 대조구에 비해 쑥 분말 첨가수준 증가에 따라 포화지방산은 높아지고 상대적으로 불포화지방산(unsaturated fatty acids)은 낮아지는 경향이 있었으나 유의차는 없고, 콜레스테롤의 경우에도 동일하게 유의적인 차이가 없었다. 전체적인 기호도는 신선육 및 조리육 공히 처리구가 낮은 점수를 얻었다. 향후 쑥 분말 급여에 대한 보다 많은 연구가 진행되어야 할 것으로 판단된다. This study was carried out to investigate the feeding effects of mugwort powder on meat quality characteristics for 42 days. The results obtained were as follows; Carcass weight(㎏) and backfat thickness(㎜) of T3 showed the lowest compared with other treatments. Grade scores were not significantly differ among the all treatments. In the proximate composition, crude ash content was higher(P<0.05) in the T3 than that of T1, while, crude fat and crude ash contents in T4 were higher(P<0.05) than those of T2. pH values were tended to low as storage period extended, in particular, those values slightly higher in the T3 and T4. Drip loss(%) was tended to increase during storage. Shear force(㎏/㎠) in all samples showed the decreased during the storage, except for Ti. L^(*) and a^(*) of T3 were slightly higher than those of T1, while, T4 was lower than T3. TBARS and VBN of all samples were significantly increased(P<0.05) as storage period extended, those values significantly higher(P<0.05) in the T3 and T4. There were no differences in saturated fatty acids, unsaturated fatty acids and cholesterol of pork meat between control(T1 and T2) and treatments(T3 and T4). The sensory score of pork samples fed with mugwort power were lower than that of control(T1 and T2) in both fresh and cooked meat. Further studied are needs on the pigs fed with mugwort powder.

비육후기 돼지 사료에 첨가되는 우지 함량 중 2%를 들깨유로 대체 급여한 돈육(T1), T1처리구에 비타민 E 250ppm 첨가 급여한 돈육(T2), 우지함량 중 2%를 오징어유로 대체 급여한 돈육(T3), T3에 비타민 E 250ppm 첨가 급여한 돈육(T4)을 1±1℃에서 28일간 저장하면서 육질특성을 조사한 결과는 다음과 같다. 저장기간에 따라 육색 L^*과 b^*값, 지방색 b^*값 및 drip loss는 증가하였다. 총단백질추출성과 보수력은 14일까지 증가 후 감소하였으며, 염용성 단백질추출성 및 지방색 L^*값은 감소하였다. 근절길이에서는 저장기간에 따라 T3구는 감소하였다. 총단백질추출성은 T1보다는 T2가 낮은 반면 T3보다는 T4가 높았다. 염용성단백질추출성은 비타민 E 첨가구들이(T2, T4) 첨가하지 않은 구들(T1, T3)에 비하여 높았으며, drip loss와 육색 a^*값은 비타민 첨가구들이 첨가하지 않은 구들에 비해 낮게 나타났다. 보수력은 T1보다는 T2가 낮은 반면 T3보다는 T4가 높았다. 지방색 L^*값은 저장 1일째는 비타민을 첨가한 처리구들이 첨가하지 않은 처리구들에 비해 높았으나, 저장 28일째에는 낮게 나타났고, b^*값은 비타민을 첨가한 처리구들이 낮게 나타나 비타민 첨가구가 drip loss, 육색과 염용성단백질 추출성에서 좋은 효과를 나타내었다. The quality of pork meat was determined as following treatments. The meat samples were obtained from pigs which had been fed finishing pig diets containing 2% perillar seed oil in beef tallow(T1), 250ppm vitamin E in T1(T2), 2% squid oil substituted of beef tallow(T3), 250ppm vitamin E in T3(T4). During storage period, meat color L^*, b^* value, fat color b^* value and drip loss were increased. The extraction amount of total protein and water holding capacity were increased until 14 days after then were decrease. The extraction amount of salt soluble protein and fat color L^* value were decreased and sarcomere length were decrease in T2 as well. T1 was higher than T2 in the extraction amount of total protein and its of T4 was higher than T3. The extraction amount of salt soluble protein of the T2 and T4 was higher than that of T1 and T3. The drip loss and the a^* value of meat color were lower in vitamin treated one than non treated one. On water holding capacity. T1 was higher than T2 and T3 was lower than T4. The L^* value of fat in vitamin treated ones was shown higher than that of non treated ones on day 1, however, it and the b^* value of the meat were low on day 28.

In order to show the effect of a vast point pollutant source on air quality of Pusan Thermoeletric Power Plant and its surrounding area, air quality around Pusan Thermoeletric Power Plant was simulated by ISCLT-2 which was supplied by EPA. For this purpose the emission amount of SO_2, NO_2 and TSP was calculated and atmospheric stability was classified for a recent decade(1985~1994) in Pusan. A result of the emission amount showed that much amount of NO_2, NO_2 and TSP are emitted from industrial area. It was clear that NO_2 is much emitted from line source and industrial area. And as a result of classification of atmospheric stability, neutral, stable and unstable state were 58%, 24.1% and 17.9%, respectivly. The result of ai quality simulation by ISCLT-2 showed that Pusan Thermoeletric Power Plant is affecting on the increse of 2.0ppb, 3.0ppb and 5.0㎍/㎥, SO_2, NO_2, and TSP respectively at its surrounding area, site A-3 which was located westward 2.2㎞ distance from Plant
