Functional dyspepsia refers to upper abdominal pain or discomfort with or without symptoms of early satiety, nausea, or vomiting with no definable organic cause. In this study, we recognized that dyspepsia was decreased with herbal medication (Banhabakchulchunma-tang) and acupuncture therapy. And we aimed to evaluate the Gastrointestinal Symptoms Rating Scale (GSRS) in these cases. The GSRS indicated that Oriental medicine treatment could be effective in the Functional dyspepsia. And it is helpful in decreasing symptoms of patients and in improving quality of life.

Background & Objective : Naeso-san(NSS) has been used for the treatment of functional dyspepsia, regarded as a gastric dysmotility disease. A main cause of gastric dysmotility is antral dilatation or antroduodenal uncoordination. Therefore, we investigated the effect of NSS on gastric motility and its mechanism of action, as well as the morphologic changes in antral dilatated rats. Methods : Antral dilatated rats were induced by wrapping a nonabsorbable rubber ring(D:6mm, W:4mm, T:1mm) around the 1st portion of the duodenum for 8 weeks. Then morphologic changes were investigated and compared with normal intact rats before and after 8 weeks. Gastric emptying was measured by administration of normal saline(NS) or NSS in normal intact and antral dilatated rats. In another series of experiments to evaluate the mechanism of NSS under delayed conditions, normal intact rats were treated with atropine sulfate(1mg/kg, s.c.), quinpirole HCl(0.3mg/kg, i.p.), $NAME(N^{G}-nitro-L-arginine$ methyl ester, 75mg/kg, s.c.) and cisplatin(10mg/kg, i.p.), respectively. The myoelectrical activity of the gastric smooth muscle was recorded in normal intact and antral dilatated rats. The contractile waves were measured for 30 minutes before and after administration of each solution(NS, NSS). Results : Body weight gain of antral dilatated rats was significantly lower than that of the controls. Futhermore, we found the thickness of the mucosal and muscular layers and surface area of the stomach increased significantly compared with controls. NSS 278㎎/㎏ improved gastric emptying more than normal saline or NSS 93mg/kg in normal intact(p=0.026) and antral dilatated rats(p=0.03). NSS enhanced gastric emptying significantly in the NAME treated group(p=0.002). NSS 278mg/kg increased the significant postprandial dominant power than that of NS in normal intact rats, whereas there was no statistical significance in antral dilatated rats. Conclusions : NSS stimulates gastric motility through the cholinergic pathway. We expect that pathologic model with antral dilatation can be used as an exprimental tool which is similar to dyspepsia and NSS would be effective especially in dysmotility-like functional dyspepsia with antral dilatation or impaired reservoir functions such as gastric adaptive relaxation.

Passive sonars employ DEMON(Detection of Envelope Modulation on Noise) processing to extract propeller information from the radiated noise of underwater targets. However, the conventional DEMON processing suffers from the interference of tonal signals because it extracts propeller signals and some types of tonal signals as well. If there are some tonals in the frequency band for DEMON processing, the conventional DEMON processing may additionally extract frequency informations originated from the interaction between different tonals. In this paper, we propose a modified DEMON processing, which can eliminate the interference of the tonals. The proposed algorithm removes tonals in DEMON processing band before demodulation processing, hence results the robustness to the interference of the tonals. Some numerical simulations demonstrate the improved performance of the proposed algorithm against the conventional algorithm.

To investigate the effect of smoking on the hearing threshold, 1,887 adult male workers who visited health care center during the period 1 January 1996 - 31 July 1997 were selected. Air-conduction hearing threshold level, diastolic blood pressure(DBP), total cholesterol, fasting blood sugar(FBS), hematocrit and obesity were measured. The data on age, occupation, and smoking were collected. Air-conduction hearing threshold in smoker was significantly higher than non-smoker in categories of 250, 500, 1000 and 4000 Hz(p<0.05). Mean values of PTA-low, PTA-mid, and PTA-high in smoker were also significantly higher than non-smoker(p<0.05). In multiple regression analysis, smoking is likely to play a significant role after controlling age, occupation, DBP, FBS, total cholesterol, hematocrit, and obesity(p<0.05). The hearing threshold was significantly increased with increasing age(p<0.05), the manufacturing worker may have higher hearing threshold(p<0.05). The higher hematocrit and the more obese, the higher hearing threshold(p<0.05). However, DBP, total cholesterol and FBS were not significantly related with hearing threshold level. In conclusion, smoking was significantly related with the hearing threshold level in adult men.

불포화지반 특성을 고려한 물리적 사면 모델 기반의 산사태 취약성 분석

김진석,박혁진,Kim, Jin Seok,Park, Hyuck Jin 대한자원환경지질학회 2014 자원환경지질 Vol.47 No.1

강우로 인해 유발되는 산사태는 강우침투로 인한 사면내 간극수압의 증가와 흙의 유효응력 및 전단강도의 감소로 인해 발생한다. 현재 광역적인 지역을 대상으로 산사태의 발생가능성을 분석하는데 주로 활용되고 있는 통계적 분석기법은 이러한 산사태 발생메커니즘을 고려할 수 없는 단점을 갖고 있다. 따라서 최근 들어 산사태의 발생메커니즘을 고려할 수 있는 물리적 사면모델이 산사태 취약성 분석을 수행하는데 많이 적용되고 있다. 그러나 사면 모델을 활용하는 기존의 연구는 강우의 침투로 발생하는 포화층 상부의 불포화층의 특성을 거의 고려하지 않고 포화층의 강도 특성만을 고려하여 분석을 수행하여 왔다. 따라서 본 연구에서는 포화층의 강도특성과 함께 불포화층의 강도 특성을 고려한 수정 전단강도 식을 활용하여 산사태 취약성 분석을 수행하고자 하였다. 또한 강우강도와 지반의 수리적 특성을 고려하여 지하수위 산정이 가능한 포화깊이비 계산식을 사면 모델과 결합하여 시간에 따른 지하수위 변화를 계산하고 이를 취약성 분석에 활용하였다. 본 연구에서는 실제 집중호우가 발생한 강원도 평창군 진부면 일대지역의 2006년 7월 14 ~ 16일의 강우강도를 이용하여 3일간의 안전율을 계산하여 산사태 취약성 분석을 수행하였으며 그 결과를 ROC 분석을 통해 실제 산사태 발생 위치와 비교하여 예측의 정확성을 분석하였다.

Association Algorithm for the Distributed Passive Linear Arrays and the Radar

김진석,Kim Jin-Seok The Korea Institute of Military Science and Techno 2005 한국군사과학기술학회지 Vol.8 No.1

PLA(Passive Linear Array) system has been primarily utilized to detect and track underwater targets, such as submarines. This system has difficulty in distinguishing between underwater targets and surface ships in a dense target environment. And a single-PLA system does not provide target state observability. At least two PLAs are necessary to observe a track uniquely. To classify and localize the underwater targets effectively, first of all, it is very of importance to discriminate the surface ships in the multi-target environment. These problems can be overcome by the association of distributed PLAs and radars. In this paper, we present an algorithm to solve the track-to-track association of the heterogeneous data from three PLAs and one radar are noncollocated with known sensor positions. Also, this paper shows the simulation results to verify the proposed algorithm.

현재 Grid 공동체에서는 여러 종류의 저장 시스템을 사용하고 있다. 그러나 저장 시스템간에 호환성이 유지되지 않아 서로 다른 클라이언트 라이브러리를 사용해야 하는 문제점이 있다. 그래서 저장 장치에 접근하는 방식을 표준화하고자 하여 GridFTP[1]라고 불리는 프로토콜이 제안되었다.
