1. The blended tabby whose warp and weft each employs a different kind of thread had been weaved since the era of the Three Kingdoms in this nation and since the period of Han in China. Especially in the 15th century. very finely weaved fabrics as the specialty of Chosun were exported to China. In the 16th century. blended tabby weaved with silk and cotton were often used for clothes as cotton was produced around the nation. And in the 17th century. blended tabby employing high quality Chinese raw silk other than existing ones were weaved. 2. It has been found in literature review that Honpo, one of Chosun's blended tabby. was manufactured mainly in Hamkyung, Cholla and Kyungsang provinces and mostly distributed through markets of Chungchong and Cholla provinces. 3. Out of the total 19 fabric pieces. 13 employed silk thread as the warp and cotton thread as the weft. Compared with the weft. in general. the warp is given more tension when weaved and more friction by spindles, being more likely to be twisted than the weft. In addition to starching, a stronger thread is requested as the warp. It is natural that in the Chosun period, silk thread more stronger than cotton thread was used as the warp to make more durable fabrics. For the weft requiring lots of threads when weaved. cotton thread was mainly used in the 17th century because the thread could be easily obtained at that time. 4. So far the study has made an empirical review of Chosun's blended tabby. especially those of the 15th∼17th century, in terms of their production and distribution. Findings from the study have some limit because they have been made focusing on the 15th∼17th century not the whole period of Chosun. Therefore it is needed to complement those findings through further studies.

Objectives : This study aims to report the effectiveness and safety of Korean medicine with thread embedding acupuncture in the treatment of trigeminal neuralgia (TN). Methods : A 73-year-old man who had suffered from severe facial pain for one year and who had had a healthy tooth extracted due to the pain is reported. He could not eat or sleep due to the severe pain. Acupuncture, thread embedding acupuncture, cupping, herbal steam, and herbal medicines were used for the treatment. Numeric Rating Scale (NRS) and adverse events were checked daily, and other outcomes (Baseline Evaluation, Visual Analogue Scale [VAS], Short Form Health Survey 36-Bodily Pain [SF-36 BP], and Patient Global Assessment [PGA]) were measured at hospital admission and discharge. During the follow-up examinations, his pain was evaluated roughly, without using any formal measurements, on the basis of a global assessment. Results : All measured parameters, including pain, quality of life, and patient satisfaction were noted to have improved at the time of discharge compared to admission: VAS from 10 to 1.5, NRS from 7-8 to 1-2, and SF-36 BP from 0 to 22.5, and the patient's global assessment was somewhat improved. He did not take any analgesics after discharge and noted only mild adverse events, like pain where the acupuncture and thread embedding acupuncture needles were inserted. His pain relief was maintained for 6 months. Conclusion : Korean medicine with thread embedding acupuncture might be a safe and effective treatment for TN. In the future, larger sample sizes and high quality randomized clinical trials are warranted to confirm its efficacy and safety.

Green Frame is precast concrete column-beam structure. There are three types on column connection. The coupler type which is one of the three, need to be improved because of unstability caused by pre-installation of column before casting the slab, and quality deterioration caused by lack of workspace. Therefore, in this study, new coupler connection type with thread rebar is suggested. The result of this study shall be used for the efficiency analysis of the new coupler connection.

Objectives : This study was conducted to examine the clinical effects of thread embedding acupuncture on lumbar herniated intervertebral disc patients. Methods : This is a retrospective study based on clinical charts. Despite the treatments of acupuncture, pharmacopuncture, herbal medicine, and physical therapy during admission period, 10 lumbar herniated intervertebral disc patients who had shown few improvements in their symptoms were selected as subjects. Thread embedding acupuncture was conducted to reduce patient pain. Patient progress was categorized into three periods based on when the embedding procedure performed. Verbal numeric rating scale (VNRS), Oswestry disability index (ODI), and a 5 step evaluation scale for satisfaction were used to analyze the outcome. Results : Regarding comparison of VNRS improvement rate, both 3 and 6 days after embedding progress showed significant difference compared to before embedding progress. ODI improvement rate showed significant difference only 6 days after embedding progress. Patients' satisfaction with treatment had increased by several degrees. Conclusion : Thread embedding acupuncture for lumbar herniated intervertebral disc patients may be effective in reducing pain and improving their quality of life.

As buildings become taller, the strength of structural materials must increase and the amount of rebar reinforcement also increases while the application of an appropriate rebar splice method in the construction process become one of the essential factors. In this research, the current status of quality check for rebar coupler is identified by an expert questionnaire and an appropriate quality check method is proposed through a quality test on specimens similar to actual on-site construction. In the test results, it was revealed that, among the quality check methods for rebar coupler joints, the coupler tightening method and face to face degree of between upper and lower rebar did not affect the strength the specimen. Therefore, it is considered to be an appropriate way to check the coupler quality check to check whether the threads are completely assembled during on-site construction through manufacture the number of threads of rebar and coupler with a margin beyond the calculated thread number.

The copper foil surface inspection system is necessary for the factory automation and product quality. The developed system is composed of the high speed line scan camera, the image capture board and the processing computer. For the system resource utilization and real-time processing, multi-threaded architecture is introduced. There are one image capture thread, 2 or more defect detection threads, and one defect communication thread. To process the high-speed input image data, the I/O overlap is used through the double buffering. The defect is first detected by the predetermined threshold. To cope with the light irregularity, the compensation process is applied. After defect detection, defect type is classified with the defect width, eigenvalue ratio of the defect covariance matrix and gray level of defect. In experiment, for high-speed input image data, real-time processing is possible with multi -threaded architecture, and the 89.4% of the total 141 defects correctly classified.

This paper addresses the factors hindering the image quality of lines in inkjet printed on polyester fabric as printing media. Lines were printed onto different types of polyester fabrics in warp and filling directions. Line image quality including line width, edge blurriness, and edge raggedness was assessed. The effect of capillary wicking on line image quality of printed spun polyester fabric is discussed. The factors on the image quality include printing position(top of the yam or between the yarn), printing direction(warp or filling), yarn structures(filament or spun), thread size(yam or fiber), finishing, and ink properties(evaporation rate). More than 30% differences in image quality results were observed by changing the printing location on the spun polyester fabric. The best results of the image quality were obtained with the printed plain and spun polyester fabrics. The fiber sizes may affect capillary size; therefore, the image quality can be dissimilar. Types of finishing materials and inks greatly improve the line image quality on spun polyester fabrics.

STATEMENT OF PROBLEM. Primary stability at the time of implant placement is related to the level of primary bone contact. The level of bone contact with implant is affected by thread design, surgical procedure and bone quality, etc. PURPOSE. The aim of this study was to compare the initial stability of the various taper implants according to the thread designs, half of which were engaged to inferior cortical wall of type IV bone(Group 1) and the rest of which were not engaged to inferior cortical wall(Group 2) by measuring the implant stability quotient(ISQ) and the removal torque value(RTV). MATERIAL AND METHODS. In this study, 6 different implant fixtures with 10 mm length were installed. In order to simulate the sinus inferior wall of type IV bone, one side cortical bone of swine rib was removed. 6 different implants were installed in the same bone block following manufacturer s recommended procedures. Total 10 bone blocks were made for each group. The height of Group 1 bone block was 10 mm for engagement and that of group 2 was 13 mm. The initial stability was measured with ISQ value using Osstell $mentor^{(R)}$ and with removal torque using MGT50 torque gauge. RESULTS. In this study, we found the following results. 1. In Group 1 with fixtures engaged to the inferior cortical wall, there was no significant difference in RTV and ISQ value among the 6 types of implants. 2. In Group 2 with fixtures not engaged to the inferior cortical wall, there was significant difference in RTV and ISQ value among the 6 types of implants(P < .05). 3. There was significant difference in RTV and ISQ value according to whether fixtures were engaged to the inferior cortical wall or not(P < .05). 4. Under-drilling made RTV and ISQ value increase significantly in the NT implants which had lower RTV and ISQ value in Group 2(P < .05). CONCLUSIONS. Without being engaged to the inferior cortical wall fixtures had initial stability affected by implant types. Also in poor quality bone, under-drilling improved initial stability.

In this study, the evidence of thread embedding acupuncture (TEA) in treating cervical radiculopathy in randomized controlled trials was investigated. We searched 16 databases up to August 22, 2022. Of the 2,644 studies retrieved, 22 randomized controlled trials (2,483 participants) were selected. Quality assessments were performed using Cochrane's risk-of-bias tool and RevMan 5.4 software. Outcome measures in the included studies typically showed TEA had a significant therapeutic effect compared with simple acupuncture and other remedies, and TEA was better than sham TEA. Catgut and polydioxanone had no difference in effectiveness, however, catgut was considered to be less safe. TEA was shown to be more therapeutic when inserted deeper into the skin. Ultrasound guided TEA was more effective and safer than conventional TEA, and using a flat blade needle was better than conventional needles for TEA. No serious adverse events were reported from using TEA, and only a few mild side effects were observed. However, the limited number and heterogeneity of the included studies, together with the unclear methodological quality, indicate that higher-quality studies need to be conducted to determine the effectiveness and safety of TEA for cervical radiculopathy.

Objectives: This study aimed to review clinical studies on thread embedding acupuncture (TEA) for the treatment of patients with post-stroke spasticity (PSS) Methods: Clinical studies related to TEA treatment for PSS were searched for in several electronic databases, including PubMed, Cochrane Library, MEDLINE, OASIS, and CNKI. After the selection/exclusion process, information on study design, disease, experimental/control group, intervention, outcome measurement, between-group differences, and adverse events was extracted. Results: A total of 13 randomized controlled trials were included in this review. The usual frequency of TEA treatment was once every 1-2 weeks, and the treatment most commonly included 4 sessions. In the dorsal area, EX-B2 and the acupoints in governing vessel meridian were commonly used. Acupoints in the meridian of the large intestine were most frequently used in the treatment of upper limb spasticity. Except for HT1, PC6, and PC8, all TEA points for treating PSS of the upper limb were on the Yang meridians. For the lower limb spasticity, the most frequently used acupoints were ST36, GB34, GB30, BL60, and BL57 on Yang meridians, and LR3, SP6, SP9, and SP10 on Yin meridians. TEA treatment showed better effects than conventional treatment for PSS in terms of spasticity, motor dysfunction, and activities of daily livings. Nevertheless, the absence of the follow-up observation, lack of sham TEA treatment, and low quality of the included studies necessitated caution in interpreting the results. Conclusions: The results of this review are expected to provide basic data on the modalities of TEA treatment for PSS and provide insights to facilitate well-designed studies in the future.
