  • Methods: It was studied on the 47 kinds of oriental medical literature for fecal blood. Results: Fecal blood means bleeding with faces from anus and indicates all the three cases such as blooding before and after evacuation, evacuation of feces mixed with blood, and simple melena. The main causes are fire(火) and deficiency of spleen qi (脾氣虛). According to the color of fecal blood and the region of the bleeding, first, if the blood color is dark-red and blood discharges after emptying the bowels, it is called deposited poison into Jang(臟毒) or distant bleeding(遠血), and if the color of blood is clear and bowel emptying occurs after bleeding, it is bloody stool due to intestinal wind(腸風) or nearby bleeding(近血). For treating methods(治法). removing heat from the blood and stopping bleeding(淸熱凉血止血), removing dampness and stopping bleeding(淸熱除濕止血), invigorating Ki for promoting Hul-controJ(益氣攝血), warming the spleen and stomach to dispel cold and stopping bleeding(溫中散寒止血) etc are applied. As for the treating prescriptionl(治法), a Hwangtotang(黃土湯). Jeoksodudanggwitang(赤小豆當歸散). Gwihwasan(槐花散). Wipungtang(胃風湯). Hwangnyeonhwan modifying(黃連丸加減). Samultang modifying(四物湯加減). Paedoksan modifying(敗毒散加減) etc are used. As for acupuncture and moxibustion(鍼灸療法). if etiology(病因) is damp-heat(濕熱), acupuncture(刺鍼) at Janggang(長强); Charyo(BL 32); Sangeoheo(ST 37)(上巨虛); Seungsan(BL 57)(承山穴), and in case of deficiency of spleen Gi(脾氣虛), acupunture(刺鍼) with tonification(補法) at I Baek(EX-UE 2)(二白); Gwanwon(CC 4)(關元); Joksamni(ST 36)(足三里) Taebaek(SP 3)(太白); Hoeeum(CC 1)(會陰穴), or mxibuston(灸) at Baekoe(GC 2O)(百會); Myeongmun9GC (命門) or the point of opposite to umbilicus among spinal vertebrae(脊中對臍穴) are used. The external treatment(外治療法) was consisted of plastering umbilicus therapy(敷臍法) and enema therapy(灌腸法).

  • In this paper, we propose a partial full duplex relay scheme for 3GPP (3rd Generation Partnership Project) LTE (Long Term Evolution)-Advanced system using a Type 1 relay. The Type 1 relay as inband relay is prohibited to transmit and receive simultaneously because of self-interference. Therefore, the Type 1 relay cannot receive synchronization signals which are transmitted to eNB. To overcoming this problem, we propose the partial full duplex relay scheme which transmits to R-UE (Relay-User Equipment) and receives from eNB (evolved NodeB) simultaneously when eNB and the Type 1 relay transmit subframes which have synchronization signals. Additionally, for solving self-interference, the Type 1 relay transmitter and receiver antennas are sufficiently sufficiently isolated and self-interference cancellation is applied for the self-interference signal from the relay transmitter. Thus, the partial full duplex relay scheme can receive synchronization signals from eNB and solve the problems of conventional solutions and we propose the partial channel estimation scheme for partial full duplex relay scheme using SCI. By extensive computer simulation, we verify that the partial full duplex relay scheme is attractive and suitable for the Type 1 relay system.

  • In this paper, we propose an asynchonous ICI (Inter-Cell Interference) mitigation techniques for 3GPP LTE MIMO-OFDMA down-link receiver. An increasing in symbol timing misalignments may occur relative to sychronous network as the result of BS (Base Station) timing differences. Such symbol synchronization errors that exceed the guard interval or the cyclic prefix duration may result in MAI (Multiple Access Interference) for other carriers. In particular, at the cell boundary, this MAI becomes a critical factor, leading to degraded channel throughput and severe asynchronous ICI. Hence, many researchers have investigated the interference mitigation method in the presence of asynchronous ICI and it appears that the knowledge of the SCM (Spatial Covariance Matrix) of the asynchronous ICI plus background noise is an important issue. Generally, it is assumed that the SCM estimated by using training symbols. However, it is difficult to measure the interference statistics for a long time and training symbol is also not appropriate for MIMO-OFDMA system such as LTE. Therefore, a noise reduction method is required to improve the estimation accuracy. Although the conventional time-domain low-pass type weighting method can be effective for noise reduction, it causes significant estimation error due to the spectral leakage in practical OFDM system. Therefore, we propose a time-domain sinc type weighing method which can not only reduce the noise effectively minimizing estimation error caused by the spectral leakage but also implement frequency-domain moving average filter easily. By using computer simulation, we show that the proposed method can provide up to 3dB SIR gain compared with the conventional method.

  • The effect of deer antler extract on muscle differentiation and muscle atrophy were evaluated to minimize muscle loss following aging. Various deer antler extracts (HWE, hot water extract of deer antler; FE, HWE of fermented deer antler; ET, enzyme-assisted extract of deer antler; UE, extract prepared by ultrasonication of deer antler) were evaluated for their effect on muscle differentiation and inhibition of 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR)-induced muscle atrophy in C2C12 cells. Morphological changes according to the effect of antler extracts on muscle differentiation were confirmed by Jenner-Giemsa staining. In addition, the expression levels of genes related to muscle differentiation and atrophy were confirmed through qRT-PCR. In the presence of antler extracts, the length and thickness of myotubes and myogenin differentiation 1 (MyoD1) and myogenic factor 5 (Myf5) gene expression were increased compared to those in the control group (CON). Gene expression of AMP-activated protein kinase (AMPK), MyoD1, and myogenin, along with the muscle atrophy factors muscle RING finger-1 (MuRF-1) and forkhead box O3a (FoxO3a) upon addition of deer antler extracts to muscle-atrophied C2C12 cells was determined by qRT-PCR after treatment with AICAR. The expression of MuRF-1 and FoxO3a decreased in the groups treated with antler extracts compared to that in the group treated with AICAR alone. In addition, gene expression of MyoD1 and myogenin in the muscle atrophy cell model was significantly increased compared that into the CON. Therefore, our findings indicate that antler extract can increase the expression of MyoD1, Myf5 and myogenin, inhibit muscle atrophy, and promote muscle differentiation.
