This paper proposed two Multi-statge Interconnection Network(MIN) that had multiple outlet to improve throughput. These proposed MINS were made of Clos MIN, well known Non-blocking MIN. These proposed MINs were called ECFS(Expanded Clos Switch Fabric) adn TCSF(Tandem Clos Switch Fabric). ECFS was consist of expanded number of switchs for multiple oulet. TCSF was consist of serial Clos MIN for multiple outlet. Performance evaluation of these proposed MINs was calculated arrival probability of packet through the MIN. In teh result, these proposed MINs with multiple outlet had higher throughput than existed MIN with single outlet. We know the fact that as the outlet of MIN increase, throughput of MIN increase.

Chronic ethanol consumption leads to memory impairment and also induces brain damage. The hippocampus has been particularly regarded as a possible target organ of alcoholic intoxication, since this structure plays a prominent function in memory processes. Cordyceps has been used as a traditional medicine in Asian countries for a long time. Different types of Cordyceps extract were reported to have various pharmacological activities including anti-tumor, anti-inflammatory, anti-viral, and immune modulatory effects. Guem Chung Cho is an artificial cultivated Cordyceps, and was supplied from GCordy (Seoul, Korea). Ethanol extract of Cordycep (50 g) was made by rotary evaporate, and resulting powder 8.29 g was obtained (yield 17%). In the present study, we investigated the effects of ethanol extract of Geum Chung Cho on short-term memory, cell proliferation and apoptosis in the hippocampus of ethanol-treated gerbils. The gerbils were divided into 5 groups (n = 10 in each group): Control group, alcohol-treated group, alcohol-treated and 0.001 mg/kg Geum Chung Cho-applied group, alcohol-treated and 0.01 mg/kg Geum Chung Cho-applied group, and alcohol-treated and 0.1 mg/kg Geum Chung Cho-applied group. Gerbils in the alcohol-treated groups were orally administered ethanol (1 g/kg) once a day for 2 weeks. Gerbils in the Guem Chung Cho-applied groups were orally administered Guem Chung Cho extract at each dosage 1 hour before ethanol consumption. Our results revealed that consumption of alcohol for 2 weeks deteriorated short-term memory, induced apoptosis, and inhibited cell proliferation, and reduced expressions of brain-derived neurotrophic (BDNF) and tyrosine kinase B (TrkB). However, Guem Chung Cho treatment alleviated alcohol-induced short-term memory impairment through enhancing cell proliferation and BDNF expression with inhibiting apoptosis in the hippocampus. Guem Chung Cho showed maximum effects at 0.1 mg/kg. Based on these results, alcohol extract of Guem Chung Cho may provide therapeutic value for the treatment of chronic alcohol-inducted brain injury. This study was supported by GCordy company.

This study was performed to investigate the pollution-free papermaking characteristics from paper mulberry by sulfomethylation pulping. Bast fibers were pulped by sulfomethylated cooking liquor and by alkali and alkali-peroxied processes for the comparison. Sulfomethylated pulping resulted in the superior pulp with high yield and better quality compared to those of alkali and alkali- peroxide pulps. Since the pulp was so bright, there was almost no need additional bleaching. Polluttant loads of sulfomethylated pulping effluent were very low in terms of pH, turbidity and color compared to those of alkali. Pollution-free effluents was accomplished by simple filtering treatment with pine bark, charred rice hull and sawdust compost. Pine bark was the most effective in reduction rate of pollutants. Key words : Korean traditional paper, Paper mulberry, Alkali-Peroxide, Sulfomethylated pulping, Effluent.

Soft-type trap-induced degradation of MoS₂ field effect transistors

Cho, Young-Hoon,Ryu, Min-Yeul,Lee, Kook Jin,Park, So Jeong,Choi, Jun Hee,Lee, Byung-Chul,Kim, Wungyeon,Kim, Gyu-Tae IOP 2018 Nanotechnology Vol.29 No.22

<P>The practical applicability of electronic devices is largely determined by the reliability of field effect transistors (FETs), necessitating constant searches for new and better-performing semiconductors. We investigated the stress-induced degradation of MoS<SUB>2</SUB> multilayer FETs, revealing a steady decrease of drain current by 56% from the initial value after 30 min. The drain current recovers to the initial state when the transistor is completely turned off, indicating the roles of soft-traps in the apparent degradation. The noise current power spectrum follows the model of carrier number fluctuation–correlated mobility fluctuation (CNF–CMF) regardless of stress time. However, the reduction of the drain current was well fitted to the increase of the trap density based on the CNF–CMF model, attributing the presence of the soft-type traps of dielectric oxides to the degradation of the MoS<SUB>2</SUB> FETs.</P>
