The purpose of this paper is to design and implement the user motion pattern control system for the simulated vehicle. After analyzing the user motion patterns in the system, the patterns are used to control the moving direction of the simulated vehicle such as forward, backward, turn right, turn left etc. The patterns in the system around are sent to the simulated vehicle in real time. In order to execute the suggested user motion pattern control system, the Kinect is used for executing the system. The Kinect recognizes the specified user motion patterns and it transmits the data to the user motion pattern control system. There are nine kinds of the user motion patterns in the system for controlling the simulated vehicle. In addition to this, some sensors are used to detect the condition of the simulated vehicle. GPS is also used to estimate the current location of the simulated vehicle and to obtain the driving information.

With the purpose of developing a objective fitness evaluation system for knits, the basic bodice pattern for knit was drafted and the suitability of the altered pattern was evaluated. For each of nine different knits, six sleeveless shirts were made with patterns that were altered by different pattern alteration rate: 0%, 30%, 40%, 50%, 60%, or 70% of the stretch rate of the knit. The panel that was composed of 25 clothing specialists evaluated the fitness of the garments. The distance from the dress form landmark to the garment landmark was measured from each experimental garment. And the results of garment fitness evaluation and the measurement of distance from the dress form landmark to garment landmark were compared. The results of this study are as follows: There was high correlation(r$\geq$0.9) between the evaluation of the panel about the garment fit and the landmarks distance. The stretch rate of knits affected the evaluation of the garment fit. The stretch rate in course of knits affected on the garment fit at crosswise direction. The suitable pattern alteration rate was lower than 30% for the knits with high stretch rate in course. It was concluded that in order to get the appropriate knit bodice pattern length, the front bodice pattern must be less shorten than the back bodice pattern. The alteration rate at hip line must be lower than for waist or bust line.

This paper describes the design and fabrication of an electronically rotated Tactical Air Navigation(TACAN) antenna using parasitic elements and PIN diode switches. We used parasitic elements arranged in a circular array and PIN diode switches to electronically rotate the antenna instead of employing a mechanically rotated antenna using motor. The antenna's physical characteristics and design features to generate the cardioid pattern and nine-lobe pattern including bearing information are described and simulated. The measured result shows a very good agreement with simulation and meets the specification of MIL-STD-291C.

Objectives Few studies to date reviewed herbal medicines prescribed to pediatric patients with coronavirus disease 2019 (COVID-19). We aimed to summarize and analyze these herbal medicines. Methods Nine databases were searched for studies published up until November 24, 2020. Nine case reports and one case series involving 17 pediatric patients were included in the study. The clinical symptoms, interventions, outcomes, pattern identification, composition, and frequency of herbal medicine administration were analyzed. Results The symptoms of pediatric patients with COVID-19 treated with herbal medicines were mild or moderate. Herbal medicines have been used to alleviate symptoms, such as fever and cough. No adverse events were reported. All of the patients who received herbal medicines were discharged from the hospital after symptomatic relief. Pattern identification revealed that the lungs were the most affected organs. Epidemic toxins, wind, dampness, and heat were the primary etiological factors. More pediatric patients with COVID-19 were prescribed a combination of herbal and Western medicines than herbal medicines alone. The frequently used herbs include Glycyrrhizae Radix et Rhizoma, Lonicerae Flos, Scutellariae Radix, Armeniacae Semen, Citri Reticulatae Pericarpium, and Astragali Radix. Conclusions Our review can serve as a reference for the treatment of COVID-19 in children.

Body image is important as it is related to self-esteem and can be enhanced by clothing and the degree of enhancement is related to clothing fit. The purpose of the paper is to find the adequate ease distribution of jacket pattern for the obese women who want to slenderize their shape by optical illusion. Subjective evaluation of the visual appearance we collected and, at the same time, 3D clothing air volume was observed for the nine types of experimental jackets with different ease distribution. As results it was found that jacket pattern for the obese women is that the front width of pattern is wider than what of back width in waist and abdomen. It was also noted that there was distance between clothing and skin in the girth around hip of jacket. 3D scanner clearly demonstrated the distribution of ease is useful to find the pattern variables responsible for the slender appearance of the obese women. The ready-to-made clothes for the obese women's clothing should be manufactured systematically in due consideration of the diversity and scarcity of the obese women's body shape.

EMG pattern recognition is essential for the control of a multifunction myoelectric hand. The main goal of this study is to develop an efficient feature projection method for EMC pattern recognition. To this end, we propose a linear supervised feature projection that utilizes linear discriminant analysis (LDA). We first perform wavelet packet transform (WPT) to extract the feature vector from four channel EMC signals. For dimensionality reduction and clustering of the WPT features, the LDA incorporates class information into the learning procedure, and finds a linear matrix to maximize the class separability for the projected features. Finally, the multilayer perceptron classifies the LDA-reduced features into nine hand motions. To evaluate the performance of LDA for the WPT features, we compare LDA with three other feature projection methods. From a visualization and quantitative comparison, we show that LDA has better performance for the class separability, and the LDA-projected features improve the classification accuracy with a short processing time. We implemented a real-time pattern recognition system for a multifunction myoelectric hand. In experiment, we show that the proposed method achieves 97.2% recognition accuracy, and that all processes, including the generation of control commands for myoelectric hand, are completed within 97 msec. These results confirm that our method is applicable to real-time EMG pattern recognition far myoelectric hand control.

The purpose of this study was to improve the clothing life of the children between the nine to twelve by making a scientific and rational basic bodice pattern. The comparison of the eight pattern drafting currently used in Korea was referred in order to make new basic pattern. Three hundred fifty-two subjects from 9 to 12 years old in Seoul area were measured on 19 items. The measurements (24 items including 19 measured items and 5 drafted items that were difficult to measure) were analyzed by mean values and correlation coefficients between each item. This new pattern attempted to set the ease for clothing from experiments of the changes of body surface in motion. On the basis of the above results, a new bodice basic pattern was developed and tested with wearing three times. Through the experiments in measuring the changes of the body surface in motion, it was concluded that it desirable to set a standard of 12cm clothing ease on the bust circumference and 4cm on the waist circumference. The correlation coefficient of the tack width to across back was relatively high (r= .677), therefore, the latter measuring items were eliminated. A grading method was adopted to determine the width and depth of neckline and shoulder slope.

This study presents a pattern drafting method for designing a slim-fit blouse for women in their twenties with a D cup bra size and various bust sizes within the standard body type range using the 3D virtual clothing system. Three participants were scanned using a body scanner, and three similar princess blouse patterns were selected. A total of nine virtual blouses were produced, with three sets made for each participant. In the initial evaluations, Pattern C received the highest score. The second pattern was designed by mending the flaws in Pattern C. However, in the eases of the front and back busts, back width and back waist were still insufficient and sleeve length was short. In the similarity evaluation between virtual and real blouses, the overall appearance was similar. Most of the corrected elements received significantly higher ratings in the third real blouse. However, the ease of the rear bust area was slightly large. In general, when drafting blouse patterns for women with large bust sizes, it is essential to increase the ease in the front bust, reduce the ease in the back bust, enlarge the waist dart, and decrease the armhole depth.
