Effects of dietary taurine on the abdominal fat weight and serum and liver concentrations of cholesterol were investigated with male broiler chicks. One-day old chicks were allocated to one of three taurine supplemented diets: 0 (control), 1 and 2%. Body weight gain of chicks fed the diet supplemented with 2% taurine decreased by 6% compared to the control (P$\prec$0.05). However, feed conversion ratio was not different among treatments. Liver weight and ratio of liver weight to body weight showed no difference among treatments. Abdominal fat weights were lower in 1% and 2% taurine supplementations by 14% and 20%, respectively, than that of the control (P$\prec$0.05). Serum concentrations of triglyceride, glucose, glutamic oxaloacetic transaminase and glutamic pyruvic transaminase were not different among treatments. However, serum concentrations of total cholesterol were higher in 1% and 2% taurine supplementations by 10% and 12%, respectively, than that of the control (P$\prec$0.05). Also serum concentrations of HDL-cholesterol increased in 1% and 2% taurine supplementations by 20% and 34%, respectively, compared to the control (P$\prec$0.05). Concentrations of total cholesterol in liver decreased in 1% and 2% taurine supplementation by 9% and 13%, compared to the control (P$\prec$0.05). Also concentrations of HDL-cholesterol in liver were lower in 1.0% and 2.0% taurine supplementation by 20% and 38%, respectively, than that of the control (P$\prec$0.05). These results showed that taurine supplementation decreased the fat storage in abdominal cavity and affected on the cholesterol metabolism in liver of broiler chicks.

In vivo metabolism study was carried out to find out the biochemical or metabolic tolerance mechanism between Diamond backmoth (DBM), Plutella xylostella and Beet armywarm (BAW), Spodoptera exigua to flupyrazofos. They showed some differences between the DBM and BAW. About 20% of flupyrazofos applied to the 3rd instar larvae of DBM was metabolized within 1 h and about 50% of that was metabolized within 4 h. The metabolites of flupyrazofos-oxon in 3rd instar larvae of DBM were increased 10 times more at 4 h than 1 h after application. The amounts of flupyrazol were nearly same between at 1 h and 4 h. The amount of unknown and origin increased 2 and 3 times more at 1 h than 4 h after application, respectively. In the 4th instar BAW larva, about 50% of flupyrazofos was metabolized within 1 h and about 70% of that was metabolized within 4 h. As metabolites, the amounts of flupyrazofos-oxon increased 2 times more at 4 h than 1 h after application. The amounts of flupyrazol increased 4 times more at 4 h than 1 h after application. The amount of unknown and origin increased 2.5 and 2 times more at 4 h than 1 h after application, respectively. From the study, it is supposed that hydrolytic enzyme, esterase, cleave the alkyl bond of flupyrazofos and conjugates with flupyrazofos. This seems to be the main tolerance mechanism of BAW to flupyrazofos.

Simvastatins are widely used to reduce endogenous cholesterol synthesis and improve hypercholesterolemia. Also, simvastatin have been shown to induce both angiogenic and angiostatic responses. In this study, It was attempted to resolve this controversy by studying the effects of simvastatin on the cell migration and invasion with the proteinases secretion and expression pattern. U-373-MG cells treated with low dose of simvastatin ($0.001{\sim}0.5\;{\mu}M$) showed the induction of migration and invasion compared with the addition of a control buffer. On the contrary, high dose of simvastatin ($1{\sim}20\;{\mu}M$) showed the reduction of migration and invasion compared with the addition of a control buffer. It was also showed that simvastatin-regulated migrative and invasive phenotypes were consistent with the secretion and expression pattern of matrix metalloproteinase-2 (MMP-2), MMP-9 and plasmin.

고밀도 유도결합 플라즈마(high density inductively coupled plasma) 식각은 GaAs 이종접합 양극성 트랜지스터(HBTs)와 고속전자 이동도 트랜지스터(HEMTs)와 같은 GaAs 기반 반도체의 정교한 패턴을 형성하는데 더욱 많이 이용되고 있다 본 연구는 고밀도 플라즈마 소스(source)인 평판형(planar) 고밀도 유도결합 플라즈마 식각장치를 이용하여 $BCl_3$ 와 $BCl_3/Ar$ 가스에 따른 GaAs 식각결과를 비교 분석하였다. 공정변수는 ICP 소스 파워를 0-500W, RIE 척(chuck) 파워를 0-150W, 공정압력을 0-15 mTorr 이었다. 그리고 가스 유량은 20sccm(standard cubic centimeter per minute)으로 고정시킨 상태에서 Ar 첨가 비율에 따른 GaAs의 식각결과를 관찰하였다. 공정 결과는 식각률(etch rate), GaAs 대 PR의 선택도(selectivity), 표면 거칠기(roughness)와 식각후 표면에 남아 있는 잔류 가스등을 분석하였다. 20 $BCl_3$ 플라즈마를 이용한 GaAs 식각률 보다 Ar이 첨가된 (20-x) $BC1_3/x Ar$ 플라즈마의 식각률이 더 우수하다는 것을 알 수 있었다. 식각률 증가는 Ar 가스의 첨가로 인한 GaAs 반도체와 Ar 플라즈마의 충돌로 나타난 결과로 예측된다. $BCl_3$ 와 $BC1_3/Ar$ 플라즈마에 노출된 GaAs 반도체 모두 표면이 평탄하였고 수직 측벽도 또한 우수하였다. 그리고 표면에 잔류하는 성분은 Ga와 As 이외에 $Cl_2$ 계열의 불순물이 거의 발견되지 않아 매우 깨끗함을 확인하였다. 이번 발표에서는 $BCl_3$ 와 $BCl_3/Ar$ 플라즈마를 이용한 GaAs의 건식식각 비교에 대해 상세하게 보고 할 것이다.

The purpose of this study is to compare the types and capabilities of smartphone apps related to tea, coffee, wine and beer. As a result of examining the capabilities of 200 tea, coffee, wine and beer apps from Apple App Store, 17 types of capabilities were identified. The study found no significant difference in the capabilities of tea and coffee apps, but there was a significant difference in the capabilities of tea and wine apps, and tea and beer apps (p<0.01). Entertainment-oriented apps take up a higher proportion of tea-related apps while wine apps, provide a higher proportion of consumer usability-oriented apps such as finding information about wine, writing notes about wine characteristics, finding nearby shops/cafes. In order to increase practical use of tea-related apps, this study proposes capabilities of coffee, wine, and beer apps as examples and presents app menu to promote development of tea-related apps.
