The purpose of this study is to design electrical stimulation system for pharyngeal dysfunction(dysphagia) in stroke patients. Pharyngeal muscle group activity is important, because contracting muscles provide the driving force at the initiation of the swallow and generate the pressure gradients necessary for bolus movement into the esophagus. Although we have many treatment methods for dysphagia, electrical stimulation system will be useful for stroke patients having dysphagia. Electrical stimulation can be divided into the body stimulation and electrodes. The body stimulation is divided again into frequency counter, time control and current measurement part. These parts are to control the current intensity, frequency and stimulating time. And they can be variable according to the patient's clinical assessment. The electrode plays a role to deliver the current from the system to the muscle. Also the position of the electrode can be variable according to the treatment method. We performed the clinical experiment with the stroke patient who has swallowing disorder. The videofluoroscopy was used for the observation. From the result of clinical experiment based on electrical stimulation, we expected that the dysfunction(in pharynx) level of the patient can be improved. However we could not have enough effectiveness of the treatment because of the number of patients, patient's adaptation and treatment period. We will design the optimized electrical stimulation system based on enough clinical experiment in the future.

The study was based on a three-stage, non-repetitive factorial experiment in which chemical-rotted kenaf fibers were treated separately with hydrogen peroxide concentrations of $0.5\%,\;1\%\;and\;2\%$, with pH solutions of 7, 9 and 11, and treatment times of 30, 60 and 90 minutes. Under optimal conditions, the study was conducted to determine the strength and elongation of kenaf fibers by the addition of chelators, penetrants and surfactants. The hydrogen peroxide concentration, solution pH and treatment time directly affected the strength of kenaf fibers. The hydrogen peroxide concentration, solution pH affected the elongation of kenaf fibers. It was found, however, that the interaction between pH and treatment time, concentration and treatment time, concentration and treatment time and pH affected the strength of kenaf fibers. Also, It was found that the interaction between pH and concentration, concentration and treatment time, concentration and treatment time and pH affected the elongation of kenaf fibers. Under the hydrogen peroxide conditions of $2\%$ concentration, pH 11 and a treatment time of 60 minutes, there were no effects on the strength and elongation of kenaf fibers with the addition of chelator SP, CA.

The purpose of this study is to search effect that GCM joint treatment gets to right and left range of motion of neck, lumbar, trunk and anke joint. Estimated body deformity using GCM body type assesment chart then measured range of motion of each region. After control group did as act freely after do experiment premeasurement control group did postmeasurement. Each region was measured by measurer who each subject person differs. Experimental group did GCM joint treatment and all measurements each region by measurer who each subject person differs three times measured. When measure with each measurement, measured after leave and walk time interval for 10 minutes. For the analysis of the resulr of experiment the results is change amount comparison increased to keep in mind except ankle joint's dorsiflexion before experiment of experimental group and control group(P<.05). Before an experiment and after an experiment of experimental group, differed to keep in mind in right and left comparison of neck rotation, dorsiflexion, plantaflexin of ankle joint in change amount comparison(P<.05). Neck lateral flexion appears and displayed significantly level right and left difference than rotation after experiment of experimental group(P<.05). Because dorsiflexion, plantefleaion of ankle joint became similar right and left significantly difference did not appear(P<.05).
Two experiments were conducted to investigate the effents of feeding single or combined probiltics on performance and intestinal micreflora of broiler chicks for five weeks. Diets based on corn and soybean meal contained 21.50, 19% CP and 3,100, 3,150kcal/kg ME for starting and finishing period, respectively. Lactobacillus salvarius isolated from chicks intestine(LSC), Lactobacillus salvarius isolated from piglet(LSP), Bacillus polyfermenticus(BP) were fed with alone and mixed ones at the level of 0.21 and 0.1% in experiment 1 and 2, respectively. Three hundred eighty four chicks were randomly assigned to eight treatments with four replicates of 12 chicks each per treatment. Weight gain, feed consumption, feed conversion ratio(FCR) were weekly measured for 5 weeks. The number of intestinal micreflora was examined at the end of experiment. In both experiments, weight gain of chicks fed probiltics tended to be similar or higher than control, but was not in LSC+LSP treatment. Feed intake was not consistent among treatments. In experiment 1, FCR of chicks fed LSC alone was the lowest of all treatments, whereas it was significantly higher in LSC+LSP treatments than control(P〈0.05). In experiment 2, LSP supplemental groups tended to increase FCR compared to the control. The number of ileal E. coli was the lowest in LSP alone treatment of experiment 1, whereas cecal E. coli was higher concentration in probiotics supplemental groups than control. Total Lactobacillus of chicks fed probiotics was decreased in ileum, but was no consestency in cecum. In experiment 2, ileal total yeast tended to be higher in probiotics supplemental groups except LSP alone supplement than control. Total Lactobacillus of chicks fed LSC or LSP alone treatments was significantly higher than control(P〈0.05).

This study was conducted to investigate the effects of mechanical stimulation and growth regulators known to control overgrowth in hot temperature tomato transplants on the seedling quality and the growth and yield after planting. Brushing and impedance were applied as mechanical stimulation, and diniconazole and hexaconazole as chemical growth regulator were used in various ways at different concentrations and treatment times. Diniconazole treatment regardless of concentration and treatment times reduced plant height, leaf area and fresh weight of young plant. Though treatments of high concentration and many times reduced the yield of tomato after planting, these of proper amount and proper times maintained the level of control. Hexaconazole treatment controlled less plant height of transplants than diniconazole, and its effect also didn't support continuously after planting. However, hexaconazole treatment reduced the yield due to little fruit number and malformed plants, and also delayed the harvesting time as compared to the control. Both brushing and impedance controlled plant height of transplants. However, impedance treatment reduced the yield due to malformed plants after planting, and also delayed the harvesting time, while brushing treatment didn't reduced growth and yield as compared to the control. From the above results, it was thought that proper application of brushing and diniconazole can control excessive overgrowth without reducing yield.

In large-type goats that were fed on dry forage twice daily, dry forage intake was markedly suppressed after 40 min of feeding had elapsed. The objective of this study was to clarify whether or not increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding suppress dry forage intake. Eight large-type male esophageal- and ruminal-fistulated goats (crossbred Japanese Saanen/Nubian, aged 3 to 6 years, weighing $72.3{\pm}2.74$ kg) were used in two experiments conducted under sham feeding conditions. The animals were fed ad libitum a diet of roughly crushed alfalfa hay cubes for 2 h from 10:00 to 12:00 h during two experiments. Water was withheld during feeding in both experiments but was available for a period of 30 min after completion of the 2 h feeding period. In experiment 1, an intraruminal infusion of artificial parotid saliva (RIAPS) in the control replenished saliva lost via the esophageal fistula and an intraruminal infusion of hypertonic solution (RIHS) in the treatment was carried out in order to reproduce the effects of changing salt content due to feed entering the rumen. In experiment 2, the RIHS control was conducted in the same manner as the RIHS treatment of experiment 1. The treatment group consisted of RIHS-with an intravenous infusion of artificial mixed saliva (VIAMS) treatment that was carried out for 3 h to prevent increases in plasma osmolality during feeding. The results of the RIHS treatment in experiment 1 showed that ruminal fluid osmolality increased and then an increase in plasma osmolality was observed. This resulted in the production of thirst sensations and the reduction of cumulative dry forage intake to 43.3% (p<0.05) of the RIAPS control. The results of the RIHS-VIAMS treatment in experiment 2 indicated that ruminal fluid osmolality was the same as the RIHS control but plasma osmolality significantly decreased, and thirst level was markedly reduced. This caused a significant increase of 31.4% (p<0.05) in cumulative dry forage intake in the RIHS-VIAMS treatment compared to the RIHS control. These results indicate that increases in ruminal fluid osmolality during dry forage feeding indirectly suppresses dry forage intake by causing an increase in plasma osmolality and subsequently inducing thirst sensations. The results of the present study suggest that marked decreases in dry forage intake after 40 min of feeding are caused by increases in plasma osmolality and subsequent thirst sensations produced by dry forage feeding.

The Clinical Study on the Body Weight Loss of Taeumin Inpatients in Stroke by Sasang Constitutional Medicinal Treatment. Purpose: It has been frequently noted that overweight and obesity have a stronger relationship to hypertension and diabetes mellitus than to the risk of stroke. The purpose of this study is to find out whether Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss. Methods: Case-control study was applied. The experiment group is the 24 Taeumin stroke inpatients who were in hospital in Kyung-Hee Oriental Hospital from July 1, 2000 to October 1 and received Sasang Constitutional Medicinal treatment. The control group is the 13 Taeumin stroke inpatients who were in the hospital during the same period but didn't receive Sasang Constitutional Medicinal treatment. In the two groups, body weight, BMI, the skin fold(cm) of triceps, suprailiac, abdominal portion, and thigh and the circumference(cm) of wrist, biceps, triceps, and W/H ratio were compared and studied for three weeks. Results: 1. In the experiment group, there were 8 women and 15 men, 23 in total and in the control group, there were 5 women and 9 men, 14 in total. 2. From two weeks later, there was a significant decrease in the experiment group in weight loss, the ratio of loss, and BMI(p<0.05). 3. Concerned with the change in the skin fold of suprailiac portion, there was a significant decrease in each group(p<0.05). 4. Concerned with the change in the skin fold of Chunchu-Hyel portion(天樞穴), thigh and in the circumference of hip, W/H ratio, there was a significant decrease in the experiment group(p<0.05). 5. Concerned with the change in the value of Lipid Profile, GOT, and GPT, only Glucose(GLU) showed a significant decrease(p<0.05) in the experiment group(p<0.05). As Conclusion, Sasang Constitutional Medicinal treatment in the stroke patients of Tae-um-in has an effect on local or general weight loss.

This study was carried out in order to examine the germination characteristics of Atractylodes japonica seeds, and it was to develop the more efficient pre-treatment and production system of the seeds. Experiment was performed by two ways-temperature control (10, 15, 20, $25^{\circ}C$) and shading treatment (full sunlight, 35, 50, 75, 95% of full sunlight). Seed pre-treatment before the each experiment was carried out by temperature (with low temperature and wetting treatment (LTW) for 0, 15, 30, 45 and 60 days) and shading treatment (with drying at room temperature (DRT), drying at low temperature (DLT) and water soaking (WS) for 48 hours). Seeds of A. japonica were germinated well under temperature control (overall 85.3~100%), especially high temperature. And, the seeds pre-treated with LTW for 45 days germinated with a 100% success rate. Under the surveying shading treatment, the highest germination rate was 95.8% with DRT and overall 63.2~95.8%. Germination rate under seeds with WS was 63.2~7.8%. As a result of surveying the whole experiment, A. japonica seeds don't need to pre-treat cause of high germination, but if it is performed with LTW for a certain period of time, it would be more productive.
The effluent from conventional nightsoil treatment plants contains nutrients, color and chlorides, in addition to residual organics and suspended solids, and thereby causes substantial pollution problems in receving water resources. In order to verify the usefullness of electrolysis in removing those residual pollutants from such conventional nightsoil treatment plant effluent, a bench scale experiment was conducted using sufficiently dilluted human nightsoil as experiment feeds. The result showed mean removals of 45% of total phosphorus and 85% of color, in addition 87% of residual BOD, 47% of residual COD and 85% of residual SS. The optimum electric current was found to be 15 ampere and the optimum hydraulic residence time 21/2 hour.
