  • The propose of the study was to evaluate the efficacy of the partial body weight support during treadmill training on the ambulation in elderly with chronic stroke. Fourteen hemiplegic volunteers participated and were divided into an experimental and control groups. In the experimental group, the body weight support during treadmill training was performed 3 times per week for 6 weeks. In the control group, usual treadmill training was applied. Before and after experiments, temporal-spatial gait parameters were measured. The date of 14 patients who carried out the whole experimental course were statistically analyzed. The results of the study were : 1. In the comparison of gait velocity before and after experiment, the gait velocity was significantly increased in the experimental group and the control group(p<.05). In the comparison of difference of the gait velocity between groups, there was not significant difference between the experimental group and the control group(p>.05). 2. In comparison of gait cadence before and after experiment, the gait cadence was significantly increased in both groups(p<.05). In the comparison of difference of the gait cadence between groups, there was not significant difference between the experimental group and the control group(p>.05). 3. In the comparison of step length before and after experiment, the step length was significantly increased in the experimental group and the control group(p<.05). In the comparison of difference of the step length between groups, there was not significant difference between the experimental group and the control group(p>.05). 4. In the comparison of vastus medialis root mean square(RMS) before and after experiment, the vastus medialis RMS was significantly increased in the experimental group(p<.05). In the comparison of vastus medialis root mean square(RMS) before and after experiment, the vastus medialis RMS was not significantly increased in the experimental group(p>.05). In the comparison of difference of the vastus medialis RMS between groups, there was not significant difference between the experimental group and the control group(p>.05). 5.

  • We use Borcherds products to give a new construction of the weight 3 paramodular nonlift eigenform fN for levels N = 61, 73, 79. We classify the congruences of fN to Gritsenko lifts. We provide techniques that compute eigenvalues to support future modularity applications. Our method does not compute Hecke eigenvalues from Fourier coefficients but instead uses elliptic modular forms, specifically the restrictions of Gritsenko lifts and their images under the slash operator to modular curves.

  • OC-SVM(One Class Support Vector Machine) avoids solving a full density estimation problem, and instead focuses on a simpler task, estimating quantiles of a data distribution, i.e. its support. OC-SVM seeks to estimate regions where most of data resides and represents the regions as a function of the support vectors, Although OC-SVM is powerful method for data description, it is difficult to incorporate human subjective importance into its estimation process, In order to integrate the importance of each point into the OC-SVM process, we propose a fuzzy version of OC-SVM. In FOC-SVM (Fuzzy One-Class Support Vector Machine), we do not equally treat data points and instead weight data points according to the importance measure of the corresponding objects. That is, we scale the kernel feature vector according to the importance measure of the object so that a kernel feature vector of a less important object should contribute less to the detection process of OC-SVM. We demonstrate the performance of our algorithm on several synthesized data sets, Experimental results showed the promising results.

  • Among the accidents and failures that occur during concrete construction, many are formwork failures which usually happen when concrete is being placed. A system of formwork filled with wet concrete has its weight at the top and is not basically a stable structure. Slab formwork consists of sheathing, stringer, hanger and shore. There are several types of adjustable shores. In construction site, pipe supports are usually used as a shore of slab formwork. In this study, pipe support systems with/without horizontal connector were measured by buckling test. Buckling load of respective pipe support system was analyzed by structural analysis program(MIDAS). Buckling load of pipe support with/without horizontal connector was got by test and structural analysis. According to these results, we know that horizontal connector made pipe support system very safe. Buckling load of pipe support with horizontal connector is 56% higher than that without horizontal connector. So horizontal connector is important in slab formwork systems. Finally, the present study results will be used to design slab formwork system safely in the construction sites.

  • The purpose of this study was to investigate the effectiveness of enteral nutritional support to cancer patients who were clinically malnourished and receiving chemotherapy after surgery. To estimate the effect of nutritional support using Greenbia(Dr. Chung's Food Cooperation, LTD., Seoul, Korea) for patients with cancer, 41 patients were participated between January 1991 to November 1991. All patients were randomized into 2 groups and 18 patients were evaluated(experimental group : 12, control group : 6). The counseling was carried out once a week for 2 months. To compare the nutrient intake before and after administration of nutritional beverage and to identify the potential effectiveness of nutritional support in this group, a record of this diet on all patients during the test period was carried out for 3 days. To evaluate the patients nutritional status, the anthropometric parameters and serum protein were checked at the begining as baseline, week 3, week 6, and at the end of the test(week 8). In the case of energy balance, no patients appeared to be positive before administration of nutritional beverage, while 2 patients among 12 were observed to be more than 100% positive after administration. There were some differences among the experimental group which had administration of nutritional beverage but most of the results of anthropometric parameters were improved. When comparing the experimental and control group, there was significant increase in body weight, body fat, arm circumference and tricep skinfold. This study suggests that enteral nutritional support can help improving the nutritional status of patients received chemotherapy.

  • The weight of soundproof panels is an important consideration in the design of both panels and supporting structures. The soundproof panels in noise barriers have to carry their net weight in wet condition respectively the reduced weight and also the weight of the above installed panels in wet condition without showing any failing. In this study, a compression test and a flexural test were performed to determine the maximum vertical load which a wood plastic composites (WPC) panel can bear. In addition, the maximum loading number and height of WPC panels in a noise barrier were calculated for full, simple, and continuous support conditions.

  • The power steering pump bracket for a passenger car which is mounted on the engine block plays a role to support the inertia forces of the pump and the reaction forces of the belt assembly. The existing bracket which is made of FCD material has some demerits such as heavy weight, lower productivity and lower reliability. Recently, AI alloy bracket has been investigated to overcome these demerits. In this study, Stress analysis and modal analysis for a existing FCD bracket and two type of AI alloy brackets were performed, and strength and natural frequency of them were estimated by using finite element method to accomplish the weight reduction. As a result, the modified shape of AI alloy bracket is proposed, and it has achieved the 45% weight reduction and the improvement of its strength and vibration characteristics.

  • Image analysis algorithm for the quality evaluation of ginseng seedling was investigated. The images of ginseng seedling were acquired with a color CCD camera and processed with the image analysis methods, such as binary conversion, labeling, and thinning. The processed images were used to calculate the length and weight of ginseng seedlings. The length and weight of the samples could be predicted with standard errors of 0.343 mm, and 0.0214 g respectively, $R^2$ values of 0.8738 and 0.9835 respectively. For the evaluation of the three quality grades of Gab, Eul, and abnormal ginseng seedlings, features from the processed images were extracted. The features combined with the ratio of the lengths and areas of the ginseng seedlings efficiently differentiate the abnormal shapes from the normal ones of the samples. The grade levels were evaluated with an efficient pattern recognition method of support vector machine analysis. The quality grade of ginseng seedling could be evaluated with an accuracy of 95% and 97% for training and validation, respectively. The result indicates that color image analysis with support vector machine algorithm has good potential to be used for the development of an automatic sorting system for ginseng seedling.
