This research investigated the effect of the Chaenomelis fructus(CMF) on Alzheimer's disease. The effects of the CMF extract on the behavior in the Morris water maze experiment; the expression of IL-1β, TNF-α, ROS on the microglial cell; IL-1β mRNA, TNF-α mRNA, CD68/GFAP and MDA on the brain tissue; the infarction area of the hippocampus, and brain tissue injury in the mice with Alzheimer's disease induced by βA were investigated. The CMF extract group showed a significant inhibitory effect on the memory deficit on the mice with Alzheimer's disease induced by βA in the Morris water maze experiment. The CMF extract group suppressed the over-expression of IL-1β, TNF-α, IL-1β and TNF-α mRNA, ROS, MDA, CD68/GFAP in the mice with Alzheimer's disease induced by βA. The CMF extract reduced the infarction area of hippocampus, and controlled the injury of brain tissue in the mice with Alzheimer's disease induced by [3A. This study suggest that CMF may be effective for the prevention and treatment of Alzheimer's disease.

본 연구는 감귤부산물 TMR 사료 급여가 한우등심의 영양성분 및 기호성에 미치는 영향을 연구할 목적으로 수행하였다. 시료는 감귤부산물 TMR 사료를 급여하지 않은 한우등심(TMR-0)과 감귤부산물 TMR 사료를 급여한 한우등심(TMR-1)으로 하였다. TMR-0는 비육우용 배합사료와 건초를 분리 급여하면서 관행적으로 사육하였으며, TMR-1은 육성기 및 비육전기 일부(약 17개월)를 TMR-0와 같은 방법으로 사육한 후 나머지 10개월(비육전기 및 후기) 동안은 감귤부산물 TMR 사료를 급여하였다. 한우등심의 수분, 조단백질, 조회분, 콜레스테롤 및 열량은 TMR-0 및 TMR-1 사이에 유의성이 없었지만, 조지방은 TMR-1이 유의하게 높았다(p<0.05). Ca 및 Na는 TMR-1이 TMR-0보다 유의적으로 높았고, P는 TMR-0가 높았으나(p<0.05), Mg, K, 비타민 $B_1$ 및 비타민 $B_2$는 시료들 사이에 유의성이 없었다. 한우등심의 구성아미노산 총량은 TMR-0 및 TMR-1이 각각 17.81 및 17.98%로 비슷하였으며, 유리아미노산 총량은 각각 139.46 및 149.15 mg/100 g으로 유의성이 없었다. 불포화지방산 중 가장 많이 함유되어 있는 것은 oleic acid로 TMR-0 및 TMR-1이 각각 45.01 및 49.38%이었고, 포화지방산 중 가장 많이 함유되어 있는 것은 palmitic acid로 TMR-0 및 TMR-1이 각각 28.39 및 26.52%이었다. 한우등심의 관능적인 맛, 풍미 및 다즙성은 시료들 사이에 유의한 차이가 없었으나, 연도 및 전체적인 기호성은 TMR-1이 TMR-0보다 유의적으로 우수하였다(p<0.05). The purpose of this research was to study the effects of feeding TMR (total mixed ration) dietary citrus by-products on nutritional composition and palatability of Hanwoo loin. Samples for the experiment consisted of Hanwoo loin that was not fed citrus by-products (TMR-0) and Hanwoo loin that was fed citrus by-products during fattening periods (TMR-1). The control (TMR-0) Hanwoo loin was fed by general practical feeding (roughages and concentrates were fed separately); the TMR-1 Hanwoo loin was fed identically to TMR-0 until 17 months yearling, but fed citrus by-products for 10 months after then. The levels of the moisture, crude protein, crude ash, cholesterol, Mg, K, vitamin $B_1$, vitamin $B_2$, total amino acids ($17.81{\sim}17.98%$), and total free amino acids ($139.46{\sim}149.15mg/100g$) were not significantly different between TMR-0 and TMR-1. The contents of the crude fat, Ca, and Na of TMR-1 were greater than those of TMR-0 (p<0.05). Oleic acid ($45.01{\sim}49.38%$) was the most abundant anions unsaturated fatty acid while palmitic acid ($26.52{\sim}28.39%$) was tile most abundant saturated fatty acid in both groups. In case of sensory scores, taste, flavor, and juiciness were not significantly different between TMR-0 and TMR-1. However, tenderness and palatability preference of TMR-1 were higher than those of TMR-0 (p<0.05).

The aim of this study was to investigate the effect of the addition of red wine on the physicochemical properties ana sensory score of cooked pork patties. The samples consisted of the pork patty without red wine(control), and 1, 3 and 5% red wine(RWP-1, 3 and 5, respectively). There were no significantly differences in the moisture$(58.1\sim58.7%)$, crude protein$(15.9\sim16.3%)$ crude fat$(23.2\sim23.7%)$, and crude ash$(2.7\sim2.9%)$ contents, and the Hunter's $a^*-value(0.2\sim0.6)$, cooking loss$(16.5\sim19.2%)$, VBN$(11.9\sim15.6mg%)$, total bacterial count($(11.9\sim15.6mg%)$ Log cfu/mL), hardness$(3,193\sim3,336\;dyne/cm^2)$, springiness$(75.8\sim79.7%)$, cohesiveness$(47.8\sim52.1%)$, gumminess$(489\sim509kg)$, chewiness$(183\sim209g)$ and strength $(1,144\sim1,199g)$ between the pork patties. Of the pork patties the $L^*$ value of the control and the b value of RWP-5 were the lowest(p<0.05). The pH and TBARS value of RWP-5 were the lowest of all the pork patties. The flavor of RWP-5 was superior to that of the other pork patties, and the taste, texture, juiciness and palatability of RWP-3 and RWP-5 were superior to those of the control and RWP-1. In conclusion, the addition of 5% red wine was most suitable for enhancing the physicochemical properties and sensory score of pork patties.

This study was carried out to investigate the effect of ultrasonic wave scanning on the quality of fried chicken breast. The ultrasonic wave scanning time was 0(US-0), 3(US-3), 7(US-7) and 10(US-10) minutes, no respective comparison here. The moisture of raw breast was higher than that of flied chicken, while the crude protein, fat and ash of fried chicken were higher than those of raw breast(p<0.05). The moisture content was influenced by the ultrasonic waves scanning, but the crude protein, fat and ash were not. The $L^*$(lightness) and $b^*$(yellowness) values of fried chicken were higher than those of raw breast but the $a^*$(redness) value of raw breast was higher than that of fried chicken. The $L^*$ value was lowest in US-0, while the $a^*$ value was not significantly different and the $b^*$ value was lowest in US-7 among the fried chicken samples(p<0.05). The fried chicken was not influenced by the ultrasonic wave scanning, indicating that the longer scanning time increased the water holding capacity. The pH ranged from 6.54 to 6.93, and the calorie of fried was higher than that of raw breast, but was not influenced by the ultrasonic wave scanning time. The VBN content ranged from 8.73 to 12.3 mg%. The TBARS value of raw breast was lower than that of flied chicken and was not influenced by the ultrasonic wave scanning time. Total amino acid was highest in raw breast and lowest in US-3(p<0.05). The taste, texture and juiciness were superior with increasing scanning time, but flavor and Palatability were not significantly different among the fried chicken samples(p<0.05).

구본경,구교헌,김지혜,정인철,이재형,Koo, Bon-Kyung,Koo, Kyeo-Hun,Kim, Ji-Hye,Jung, In-Chul,Lee, Jae-Hyung 한국세라믹학회 2009 한국세라믹학회지 Vol.46 No.4

AlON was fabricated by the pressureless reaction sintering of $Al_2O_3$-AlN powder mixtures. The ratio of AlN to $Al_2O_3$ as well as various sintering aids were the main variables for this study. The optimum ratio of AlN in the $Al_2O_3$-AlN mixture was approximately 35.0 mol%. For the sintering aids, only when a small amount of MgO was added together with $Y_2O_3$ and BN, AlON specimens could be sintered to a full density with negligible pores and high transparency. Other combinations of $Y_2O_3$, BN, CaO and MgO resulted in enough pores in the sintered specimens to have in-line transmittance only between 0% and 30%. The in-line transmittance reached over 80% after sintering at $1975^{\circ}C$ for 10 h for the specimen containing 0.15 wt% MgO, 0.08 wt% $Y_2O_3$ and 0.02 wt% BN.

Permutation and combination are the part of mathematics which can be introduced the pliability and diversity of thought. In prior studies of permutation and combination, there treated difficulties of learning, strategy of problem solving, and errors that students might come up with. This paper provides the method so that meaningful teaching and learning might occur through the systematic approach of permutation and combination. But there were little prior studies treated counting numbers that basic of mathematics' action. Therefore this paper tries to help the understanding of permutation and combination with the process of changing from informal knowledge to formal knowledge.
