  • Objective : Kuesu point is a newly discovered point, it is located in 3-cun from the centre of sacrum laterally, paralleled to the 4th foramen on the sacrum. This controlled trial was to evaluate the superior effect of Kuesu point on back pain which radiated to lower extremities. Methods : Randomized Controlled Trial (RCT) and Single Blind in patient was designed. Patients (n=31) were randomized to two groups, Kuesu-point acupuncture group (Group A, n=16) and non Kuesu point acupuncture group (Group B, n=15). Group A was acupunctured on B25 (大腸兪), B26 (關元兪) and B60 (崑崙) with Kuesu point. Group B was acupunctured on the same points without Kuesu point. The clinical subjects were female patients. Beside acupuncture, the other therapies were excluded. Clinical period was three weeks total. Each group was treated 4-5 times per week for 3 weeks. The outcome measurements were The Estimation Index of Backache (quality of life), Pain Rating Scale (pain intensity) and other physical examinations (ROM, SLR, etc.). Results : 31 patients (Group A: n=16, Group B: n=15) were Randomized, 6 of them dropped out. Eventually 25 patients (Group A: n=15, Group B: n=10) were included in the analysis. Group A acupunctured on Kuesu point scored more significant Estimation Index of Backache and lower PRS (Pain Rating Scale) than Group B acupunctured without Kuesu point (p=0.003/2). It turned out that the group acupunctured on Kuesu point show meaningful high improvement index. And other examination's results showed that the treatment effects of Group A are twice as better as Group B. Conclusion : These results suggest that Kuesu point acupuncture was more effective on lower back pain and improved the life quality of patients, being compared with non Kuesu point acupuncture.

  • Experimental investigation into the behaviour of half-scale brick masonry panels were conducted under cyclic loading normal to the bed joint and parallel to the bed joint. For each cycle, full reloading was performed with the cycle peaks coinciding approximately with the envelope curve. Unloading, however, was carried out fully to zero stress level and partially to two different stress levels of 25 percent and 50 percent of peak stress. Stability point limit exhibits a unique stress-strain curve for full unloading but it could not be established for partial unloading. Common point limit was established for all unloading-reloading patterns considered, but its location depends on the stress level at which unloading is carried to. Common point curves were found to follow an exponential formula, while residual strains versus envelope strains can be expressed by a polynomial function of a single term. The relation between residual strain and envelope strain can be used to determine the stress level at which deterioration due to cyclic loading began.

  • Research on object detection algorithms using 2D data has already progressed to the level of commercialization and is being applied to various manufacturing industries. Object detection technology using 2D data has an effective advantage, there are technical limitations to accurate data generation and analysis. Since 2D data is two-axis data without a sense of depth, ambiguity arises when approached from a practical point of view. Advanced countries such as the United States are leading 3D data collection and research using 3D laser scanners. Existing processing and detection algorithms such as ICP and RANSAC show high accuracy, but are used as a processing speed problem in the processing of large-scale point cloud data. In this study, PointNet a representative technique for detecting objects using widely used 3D point cloud data is analyzed and described. And RandLA-Net, which overcomes the limitations of PointNet's performance and object prediction accuracy, is described a review of detection technology using point cloud data was conducted.

  • Objectives The purpose of this study was to compare the effect of supine JS cervical therapy and muscle release/strengthening technique in patients with acute neck pain caused by traffic accidents. Methods We studied 42 patients with acute neck pain caused by traffic accidents from July 1, 2019 to November 30, 2019. The study was conducted as a retrospective study which analyzes the patient's medical records. 21 patients (group A) had received supine JS cervical therapy and 21 patients (group B) had received muscle release/strengthening technique. We used the neck disability index (NDI) and visual analog scale (VAS) to evaluate improvements in symptoms and pain, and used the five point Likert scale to evaluate patient's satisfaction with chuna manual therapy. In each group, we compared the NDI and VAS of hospitalization day to those of 5 days later. Then we compared the NDI, VAS variation and five point Likert scale between the groups. Statistical analysis was conducted using the IBM SPSS for windows 25.0. Result Both group A and group B showed a statistically significant decrease in the NDI and VAS on the 5th day of hospitalization. In group A, there was a statistically significant decrease in the NDI compared to group B. The VAS and Five Point Likert Scale decrease was greater in group A than in group B, but the difference was not statistically significant. Conclusion We found that using supine JS cervical therapy may be more effective than muscle release/strengthening technique in acute stage after traffic accidents.

  • This study evaluates the fit preference of the tailored jacket according to body types for 20's adult women through a comparison of real and virtual fit. A five point fit evaluation scale utilizing a wearer acceptability scale by Shen and Huck was used to evaluate the degree of the preference of real and virtual fit. This scale contained 23 items in three categories: front fit, back fit, and side fit. For each item, 5 responses from 'too tight' fit (1 point) to 'too loose' fit (5 point) were possible. The middle position for each fit criterion indicated a 'good' fit (3 point). The data were analyzed with a t-test using statistical program SPSS 17.0. According to the results, there were no significant differences ($p{\leq}.05$) between the real and virtual fit preference in total measurement items such as front collar, lapel and roll line, front shoulder slope, front armhole, front waist, abdomen, sideseam, hemline, front silhouette, side shoulder, side armhole, side sleeve width, side hip, side silhouette, back collar stand, upper back, back armhole, back waist, back hip, back silhouette except front bust, side waist, and back center back. The factor that caused a difference in the fit preference between the real and virtual fit evaluation was a specific body type such as Body Type A that indicated a small bust circumference and a big hip circumference.
