  • In this paper, we propose a processing speed improvement by adding a parallel processing based on device(graphic card) into a road region extraction by host(PC) based serial processing. The OpenCV CUDA supports the many functions of parallel processing method by interworking a conventional OpenCV with CUDA. Also, when interworking the OpenCV and CUDA, OpenCV functions completed a configuration are optimized the User's device(Graphic Card) specifications. Thus, OpenCV CUDA usage provides an algorithm verification and easiness of simulation result deduction. The proposed method is verified that the proposed method has a about 3.09 times faster processing speed than a conventional method by using OpenCV CUDA and graphic card of NVIDIA GeForce GTX 560 Ti model through experimentation.

  • Objectives : Chim-Gu-Kyung-Heom-Bang(CGKHB; 鍼灸經驗方) is the needle and moxa specialized document written by the doctor specialized in needle and moxa treatment of Joseon(朝鮮), Heo Im(1570-1647). The document was published in April 1644(22nd year of King Injo). CGKHB contains the needle and moxa treatment techniques accumulated by the Joseon Dynasty as well as the personal experience of Heo Im. The aim of this study is to restore the past treatment method as a method of Needle Insertion Method at CV12(NIM-CV12, needle to penetrate blood vessel technique) in CGKHB.. Methods : Through Dong-Yi-Bao-Gam(DYBG; 東醫寶鑑), the implication of Korean medicine study of the Jungwan(CV12) has been studied. Next is the contemplation of the NIM-CV12 of CGKHB with the Acupuncture Treatment Using Jungwan(中脘鍼法) of Park Tae-won and Acupuncture Treatment for Byeokjeok(癖積鍼法) of "Geup Yubang". Results and Conclusions : 1. CV12 is one of the acupuncture points representing stomach(脾胃), middle energizer(中焦), phlegm-fluid retention(痰飮) and greater yin(太陰). 2. NIM-CV12 of CGKHB is the technique to penetrate the needle into the CV12 strictly relying on tactile sense of a person who give the penetration. This CV12 administration was carried out at intervals of every 7 or 8 day. During the administration period, the patient was not allowed to intake excessive amount of food. 3. The Acupuncture Treatment Using Jungwan(中脘鍼法) of Park Tae-won and Acupuncture Treatment for Byeokjeok(癖積鍼法) of "GeupYubang", existed in the same era of the NIM-CV12 of CGKHB, have similar linkage to the NIM-CV12 of Heo Im.

  • In this paper, we propose a method to determine whether there is a defect by using the similarity between ROIs (Region of Interest) of the standard image and ROIs of the image which is corrected in position and rotation after capturing the vehicle headlight. The degree of similarity is determined by the template matching based on the histogram of image, which is a some modification of the method provided by OpenCV where template matching is performed on the raw image not the histogram. The proposed method is compared with the basic method of OpenCV for performance analysis. As a result of the analysis, it was found that the proposed method showed better performance than the OpenCV method, showing the accuracy close to 100%.

  • Objectives : This study aimed to investigate the difference of abdominal skin temperature responses following moxibustion comparing stimulation method. Methods : Moxibustion was applied on the acupuncture points of $CV_4$, $CV_6$, $CV_{12}$. Thirty healthy men were randomly divided into two groups, one receiving a single moxibustion stimulation in three locations '$CV_4{\cdot}CV_6{\cdot}CV_{12}$'(n=15) and the other receiving triple moxibustion stimulations in one location '$CV_{12}$'(n=15) for 30 min. To obtain the skin temperature on abdominal region, a thermograph was used. Three arbitrary frames(the upper abdominal, lower abdominal, whole abdominal regions) were made to analyse skin temperature. Thermographic images were obtained at before and after the procedure of indirect moxibustion and 5, 10, 15, 20, 25, 30 min afterwards. Results : An increase in skin temperature on the three abdominal regions was observed following both one point and three points moxibustion administrations. Significant increase in skin temperature of the whole abdominal region was observed at 30 min after the procedure of three points moxibustion compared with one point moxibustion stimulation. A tendency of skin temperature changes over time was observed. Conclusions : In this study, skin temperature of lower abdominal region does not increase after triple moxibustion stimulations on $CV_{12}$. Administration of single moxibustion on $CV_4$, $CV_6$, $CV_{12}$ makes greater changes in skin temperature on the whole abdominal region than triple moxibustion on $CV_{12}$.

  • In this study, an analytical method was developed for residual metamizol in beef and pork using LC/MS/MS. 4-methylaminoantipyrin (MAA), the main metabolite of metamizol was targeted for analysis instead of its parent compound. MAA was simply extracted from meat by acetonitrile, purified and then analyzed by multiple reaction monitoring method (MRM). Standard addition method was used for calibration. The calibration curves showed the linearity of $r^2$ > 0.99 for both matrices included. The developed method was validated by six-time intra-lab tests and inter-lab tests with two other institutes. The validation of the whole procedure for beef showed the intra-lab accuracies of 78-102% (CV 5.5-9.1%) and the inter-lab accuracy of 98% (CV 14%); the intra-lab accuracies of 95-99% (CV 3.9-5.6%) and the inter-lab accuracy of 111% (CV 13%).

  • Currently, to prevent the spread of COVID-19 virus infection, gathering of more than 5 people in the same space is prohibited. The purpose of this paper is to measure the distance between objects using the Yolov5 model for processing real-time images with OpenCV in order to restrict the distance between several people in the same space. Also, Utilize Euclidean distance calculation method in DeepSORT and OpenCV to minimize occlusion. In this paper, to detect the distance between people, using the open-source COCO dataset is used for learning. The technique used here is using the YoloV5 model to measure the distance, utilizing DeepSORT and Euclidean techniques to minimize occlusion, and the method of expressing through visualization with OpenCV to measure the distance between objects is used. Because of this paper, the proposed distance measurement method showed good results for an image with perspective taken from a higher position than the object in order to calculate the distance between objects by calculating the y-axis of the image.

  • Purpose: We intended to observe the relations between Chiljehyangbuhwan and abdominal temperature according to primary dysmenorrhea severity. Methods: We selected the 100 primary dysmenorrhea patients by the screening tests (first screening test-inquiry, second screening test-clinical test, additionally WHR (Waist-to-Hip ratio) by Inbody 2.0). By the fixed blocked randomization and double blind method, Chiljehyangbuhwan or placebo was administered for 1 menstration period. Finally, 69 patients remainded. Before and after administration, we measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV12 / CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by VRS (verbal rating scale) and MVRS (multidimensional verbal rating scale). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, Chiljehyangbuhwan was correlated to ${\Delta}T$ (CV12 and CV3 / CV12 and CV4). In case of VRS, Chiljehyangbuhwan was not correlated to ${\Delta}T$. Statistically they showed significant result (p<0.05). Conclusion: The primary dysmenorrhea patients showed that severity by MVRS was connected with ${\Delta}T$ (CV12 and CV3 / CV12 and CV4) after Chiljehyangbuhwan administration. So we can consider Chiljehyangbuhwan effects the abdominal temperature according primary dysmenorrhea severity.
