Objectives : The aim of this study was to evaluate gastrointestinal parasympathetic nerve activation and pyloric valve function in patients with functional dyspepsia through analysis of bowel sounds and to investigate clinical characteristics associated with the parameters of bowel sounds. Method : We surveyed clinical characteristics of patients by using a questionnaire about functional dyspepsia. Bowel sounds were recorded for 15 minutes during fasting state and for 40 minutes during postprandial state. We then classified the patients into 3 groups by abnormal states of bowel sounds, specifically by the percentage of B.S. and dominenet frequency, and studied clinical characteristics in each group. Results : Among the 182 subjects, patients who had low activity of parasympathetic nerve were 25.8% and showed a tendency of female-dominant, family history and more frequent abdominal pain. Those who had pyloric valve disturbance were 24.1% and showed no tendency by sex distribution, family history and complained of indigestion sensation. Patients who had both disorders were 10.9%, and their clinical characteristics were non-specific. Conclusion : Analysis of bowel sounds may be useful in evaluating pathophysiological factors of functional dyspepsia.

Objective : The aims of this study were to observe how body weight and gastric morphology were changed and whether gastric emptying was impaired in rats with partial pyloric obstruction. and to evaluate whether electroacupuncture was able to restore delayed gastric emptying. Methods : Partial pyloric obstruction was induced by wrapping a nonabsorbable rubber ring around the 1st portion of the duodenum for 2 weeks. Body gain and morphologic changes of stomach were investigated and compared with normal intact rats. Gastric emptying was measured by numbering expelled glass of beads in rats. Rats were divided into 4 groups(non-acupuncture, manual acupuncture. 3Hz-electroacupuncture. 60Hz-electroacupuncture). Stimulus intensity in two electroacupuncture groups was 1.2 times of pain threshold. Results : Partial pyloric obstruction produced a significant loss of body weight and induced a significant increase of gastric surface area. The 60Hz electroacupuncture-stimulated group significantly restored the delayed gastric emptying compared to the other groups of rats with partial pyloric obstruction. Conclusion : 60Hz electroacupuncture stimulation on Zusanli(ST36) showed significant restoration of delayed gastric emptying in rats with partial pyloric obstruction.

환자 맞춤형 대뇌동맥륜의 형상 조건에 따른 혈류역학 인자 분석

The Circle of Willis (CoW) is responsible for supplying blood form the heart to the cerebral arterioles and capillaries. Since CoW has a ring-like shape, three inlets (left & right internal carotid artery and basilar artery) and several outlets (middle cerebral artery, anterior communicating artery and posterior cerebral artery), it is difficult to analyze blood circulation and hemodynamics factors in blood vessels with an invasive method. To overcome difficulty, the computational fluid dynamics (CFD) is used for hemodynamics analysis. To analyze hemodynamics parameters, previous studies don’t consider the shape of CoW, but only the disease occurrence or the region of interest (RoI). In this study, Using CoW model and RoI model, comparing hemodynamics factors such as 3D streamline, wall shear stress and pressure according to models.

The purpose of this study is to develop value-added functional gruel by adding fresh burdock & burdock powder. For burdock, we put fresh burdock (1.0, 2.0, 3.0, 4.0%) and burdock powder(0.3, 0.6, 0.9, 1.2%) into burdock gruel and get results from mechanical tests and sensory tests. Moisture content of fresh burdock gruel increased with more addition of fresh burdock, while burdock powder gruel had less moisture content as the addition of burdock powder increased. Lightness and pH decreased in both groups as more amount of burdock was added. From the result of an attribute difference test, 4% fresh burdock gruel showed the strongest burdock flavor and astringent taste. Among the burdock powder groups, the gruel added with 1.2% burdock powder scored the highest point in color intensity, graininess, savory taste, astringent taste, thickness and aftertaste. For overall acceptability, the gruel added with 3% fresh burdock scored the highest point and the gruel added with 0.6% burdock powder was the highest among the burdock powder groups. Based on the results of this study, the gruel added with 0.6% burdock powder and the gruel added with 3% fresh burdock were the optimum for their good characteristics and overall acceptability when produced.

Changes in Light Transmittance of Greenhouse Covering Materials and Cucumber Growth as Affected by Particulate Matter

In recent years, fine and yellow dust pollution has become serious in Korea and has negatively affected crop production. Particulate matter (PM) adheres to greenhouse coverings, and it reduces the amount of solar radiation transmitted into a greenhouse. A reduction in light transmittance can have a direct effect on crop photosynthesis and an indirect effect on air temperature in a greenhouse, which can lead to differences in crop yield. The objectives of this study were to investigate the changes in light transmittance of different cover materials by PM and to determine the changes in cucumber growth in a greenhouse due to reduced light transmittance. We measured the changes in light transmittance of polyethylene (PE) and polyolefin (PO) films in the PM generation chambers. Also, cucumber plants were cultivated in a greenhouse with four different light reduction treatments (0, 10, 20, and 30% reduction of light transmittance). The initial light transmittance of PO film was higher than that of PE film and the decrease in light transmittance of PO film due to PM was less than that of PE film. The vegetative growth of cucumber was promoted under the reduced light transmittance treatments; however, the yield of cucumber was highest in the control (0% reduction of light transmittance). From the results, we confirmed that PO film was less PM adhesion and that cucumber yield during the spring season can be reduced by the reduction in light transmittance due to PM.

PERT技法에 의한 費用增減이 利益管理에 미치는 影響 : 費用增減과 資本利益率과의 關聯性을 중심으로 with focus in conection with increase and decrease of cost and return on capital

洪仁義 충남대학교 경영대학원 1978 經營學論文集 Vol.5 No.-

PERT developed in the United States is widely utilized for scheduling and shortening the work schedule in the fields of production management. Such sophisticated types as PERT/COST, MCX, and so on handling moneyvalues are only used for cost management but they are not developed to have linkage with profit management for total management view point. Being partial optimum can not be identified by total business optimum, total management system should be prepared and operated in pursuit of ultimate business goals in a total business point of view. Since profitabilty's being regarded as ultimate business goal, PERT should be improved in order to expect desirable effects from the stage of micro and partial management system to the stage of having linkage with profit management system. Shortening the time and downing the cost which can not improve profit rate of invested capital is no more than ineffective behaviors. But a little increase of cost and capital profit rate would be desirable and reasonable to business goal. As it was revealed in this study. cost was increased by shortening the schedule but the capital profit rate was improved by creating reinvestment opportunities and increasing sales volume. Financial analytic rule of PERT should be formed on the basis of profit management and PERT operation system should be prepared on the basis of objective profit rate. And on every stage of shortening the schedule. PERT should be checked financially and bettered to attain objective profit rate. This study tried to search forthe rules of measuring the effect in the financial point of view by analyzing the relevant literature and reallistic data.

BALB/c 마우스의 배아 간장에서 TIS21 유전자 발현

이명숙,홍인아,임인경 아주대학교 의과학연구소 1996 아주의학 Vol.1 No.1

TIS (TPA inducible sequence) genes are known as the primary response genes in the SW3T3 fibroblast treated with TPA. TIS21 and TIS I genes are constitutively expressed in the BALB/c mouse thymus, lung, spleen and stomach. In order to understand the function of TIS21, we investigated the changes in its expression in the BALB/c mouse, from embryo to 6 months. Northern blot hybridization results showed an increase in TIS21 expression in the whole embryo in the second week of gestation. Further investigation showed that the expression was particularly strong in the embryonic liver. After birth, on the contrary, TIS21 expression disappeared in the liver. In order to confirm the northern results, we used in situ histochemical hybridization to determine the tissues which express TIS21 mRNA during murine embryonic development. Embryonic liver and brain from a 15.5-day-old rat embryo showed strong expression of TIS21 gene : the gene was expressed in the whole embryonic liver and in the neuroepithelium near the lateral ventricle of the brain at this stage. Liver is known to be the primary locus of hematopoiesis during murine embryonic development. Transient expression of TIS21 in the embryonic liver strongly suggests an important role for TIS21 during the embryonic hematopoiesis.
