Ping Feng,Xiao-li Wang,Chao Zhang,Wei Sun,Dai-min Chen 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.12

According to the mechanism of EMG signal, we know that the sacrificial electrical signal is with weak signal, low frequency, alternating, nonlinear and non-stationary characteristics. Nonlinear analysis includes higher order spectral analysis and fractal and chaos analysis.Chaos theory is one of the main parts of nonlinear science, and the electrical signal of the surface has a strong randomness, so we could consider the nonlinear analysis of EMG signals from the perspective of chaos. We mainly studied on the nonlinear analysis algorithm of EMG signal detailedly in this paper. Experiments show that,according to the quantitative analysis of several important parameters of rolling massage with chaos theory, we can measure objectively the action situation of related muscle groups in the operation course, then guide the professional massage students to understand the norms of operation in training of operation and help to lead their manipulation to the best power structure.

韓國性徹法師在Sermon of One Hundred Days對《大般涅槃經》的解讀

趙威維 ( Chao¸ Wei-wei ) 성철사상연구원 2020 퇴옹학보 Vol.17 No.-

퇴옹성철(1912-1993)은 한국의 유명한 스님으로 해인사에서 출가했으며, 1967년 해인사 방장에 추대되었고, 1981년 대한불교조계종 제6·7대 종정을 역임했다. 현대 한국불교를 대표하는 성철 스님은 1967년 해인사 방장 재임 당시 불교의 핵심인 중도관과 선종이 중시하는 불성 문제를 체계적으로 강설했다. 이를 책으로 엮은 것이 『백일법문』이다. 이 책의 제5장에 『대반열반경』과 관련된 부분이 있다. 여기서 성철 스님은 『대반열반경』의 4단락을 인용해 『대반열반경』의 중도, 불성, 12연기, 연기의 지혜, 수행차제 등에 대해 해설했다. 스님은 중도를 핵심으로 여러 개념들을 요약하고, 중도사상을 선양했다. 특히 공과 유에 대한 여러 분석들에서 벗어나 곧바로 수행에 대한 가르침으로 나아갔다. 스님은 돈오돈수와 『대반열반경』은 깊은 관련이 있다고 주장했다. 경문을 인용해 자신의 주장을 증명함과 동시에 『대반열반경』의 불성설(佛性說)을 깨달음인지 아닌지를 판정하는 표준으로 삼았다. 이로써 성철 스님이 『대반열반경』을 중시했음과 성철 사상과 그의 수행실천을 연구할 때 당연히 『대반열반경』에 많은 관심을 가져야 됨을 알 수 있다. Venerable Sungchol(1912-93) is a Seon Master in Korea. The Sermon of One Hundred Days is a quotation that Master Sungchol teaches what is the Buddhist truth at Haein Temple in1967. In this Sermon, Master makes a clear narration of the middle way, the highest principle in Buddhism, and interprets many sūtras, including MahāpranirvāṇaSūtra. It is an important sūtra to Master, because he quotes many passages of this sūtrato support his claim, ‘sudden awakening and sudden practice’. He uses the middle way to explain some major concepts in this sūtra, such as buddha nature (buddha-dhātu), the wisdom of seeing the twelve links of dependent origination, dharma-dhātu and nirvāṇa, and then they are integrated into the middle way. This enables Master’s claim to be established.

Bi, Wei-Wei,Zhang, Wei-Hua,Yin, Gui-Hua,Luo, Hong,Wang, Shou-Qin,Wang, Hongran,Li, Chao,Yan, Wei-Qun,Nie, De-Zhi Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.14

Background: To determine the amount of co-expression of IDO and EGFR in breast cancer patients. Materials and Methods:In order to obtain the distribution of co-expression of IDO and EGFR in breast cancer, we tested 110 breast cancer paraffin tissue blocks with immunohistochemical methods. Then we investigated the relationship between the diagnostic and pathologic characteristics (tumor size, lymph node status, histologic grade, the gene expression of ER, PR, HER2, p53, Ki67 and PCNA) with the situation of co-expression of IDO and EGFR by reviewing the medical records of 32 breast cancer patients. Results: Among 110 breast cancers, 32 cases demonstrated IDO and EGFR co-expression (29.1%), IDO and EGFR synchronous co-expression being found in 19.1% and asynchronous in 10.0%. Conclusions: IDO and EGFR were co-expressed in breast cancer, including synchronous and asynchronous co-expression. The results suggest that considering IDO and EGFR as two indicators for breast cancer treatment or prognosis analysis provides a potential option of individual treatment for the portion of breast cancer patients with co-expression of IDO and EGFR.

Fire resistance of high strength fiber reinforced concrete filled box columns

Chao-Wei Tang 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.23 No.5

This paper presents an investigation on the fire resistance of high strength fiber reinforced concrete filled box columns (CFBCs) under combined temperature and loading. Two groups of full-size specimens were fabricated. The control group was a steel box filled with high-strength concrete (HSC), while the experimental group consisted of a steel box filled with high strength fiber concrete (HFC) and two steel boxes filled with fiber reinforced concrete. Prior to fire test, a constant compressive load (i.e., load level for fire design) was applied to the column specimens. Thermal load was then applied on the column specimens in form of ISO 834 standard fire curve in a large-scale laboratory furnace until the set experiment termination condition was reached. The test results show that filling fiber concrete can improve the fire resistance of CFBC. Moreover, the configuration of longitudinal reinforcements and transverse stirrups can significantly improve the fire resistance of CFBCs.

Residual properties of high-strength fiber reinforced concrete after exposure to high temperatures

Chao-Wei Tang 사단법인 한국계산역학회 2019 Computers and Concrete, An International Journal Vol.24 No.1

Thermal energy from high temperatures can cause concrete damage, including mechanical and chemical degradation. In view of this, the residual mechanical properties of high-strength fiber reinforced concrete with a design strength of 75 MPa exposed to 400-800°C were investigated in this study. The test results show that the average residual compressive strength of high-strength fiber reinforced concrete after being exposed to 400-800°C was 88%, 69%, and 23% of roomtemperature strength, respectively. In addition, the benefit of steel fibers on the residual compressive strength of concrete was limited, but polypropylene fibers can help to maintain the residual compressive strength and flexural strength of concrete after exposure to 400-600°C. Further, the load-deflection curve of specimen containing steel fibers exposed to 400-800°C had a better fracture toughness.

Laparoscopic hepatectomy for the treatment of Caroli’s disease: a case report

Chao-bo Chen,Wei-dong Hu,Wan-wen Zhao,Yan-yan Gu,Hong-wei Hou,Zheng Pan 대한외과학회 2018 Annals of Surgical Treatment and Research(ASRT) Vol.94 No.3

Caroli disease is a rare congenital disorder characterized by nonobstructive dilatation of intrahepatic ducts. In cases with symptomatic intrahepatic manifestations, treatment should correspond to the type with hepatic resection for localized disease and transplantation for diffuse forms. If possible, complete resection of the cysts can cure the symptoms and avoid the risk of malignancy. A 66-year-old woman presented to Wuxi Xishan People's Hospital with recurrent intermittent upper quadrant abdominal pain. Further examinations suggested the diagnosis of Caroli disease limited to the left hepatic lobe. She underwent laparoscopic hepatectomy. Pathological examination confirmed the diagnosis of Caroli disease, and no malignancy was found. There were no immediate complications and no long-term complications after one and one-half years of follow-up. Laparoscopic hepatectomy could be a feasible, safe treatment option for localized Caroli disease

Blast-Resistance and Damage Evaluation of Concrete Gravity Dam Exposed to Underwater Explosion: Considering the Initial Stress Field

Chao Wang,Peiyong Wei,Xiaohua Wang,Sherong Zhang,Wei Cui 대한토목학회 2021 KSCE JOURNAL OF CIVIL ENGINEERING Vol.25 No.8

There is an increasing concern on the vulnerability of concrete gravity dams under blast loads. To a better evaluation of the blast-resistance, the effect of the initial stress field is taken into consideration herein. Firstly, a fluid-solid coupling numerical model is established to investigate the blast-resistance of concrete gravity dams. The numerical results indicate that the initial stress field has non-neglectable effect on the shock wave propagation, blast vibration, and failure mode of concrete gravity dams. The damage of dam base may be overestimated without the consideration of initial stress field. Moreover, a parametric study are carried out for further investigations of the dynamic responses and damage properties under various explosion scenarios (explosive charge, detonation depth, and standoff distance). With the consideration of the initial stress field, it can be concluded that the dam head nearest the explosive source is the weakest part, and the safety of the dam base is another important consideration, which may lead to severe dam-break floods. At last, a new method is proposed and recommended to evaluate the blast resistance of the whole concrete gravity dam, where the blast-induced vibration and penetration depth of cracks are suggested for the dam crest and dam base, respectively.

Chao-Wei Dong,Le Giang Tran,박우태 대한기계학회 2021 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.35 No.2

In this study, a polydimethylsiloxane (PDMS) membrane electrolysis micropump activated by a miniaturized wireless power transfer (WPT) system is introduced. The micropump system has total dimensions of 20 × 14 × 8.2 mm 3 . Combined with a compact WPT system, the micropump enables the delivery of drugs to the treatment area on demand. The WPT system consists of an impedance matching network and a two-stage voltage multiplier. Voltages ranging from 0.8 V to 1.3 V can be generated at different operating distance of 8 cm to 20 cm away from the RF source. The micropump is capable of delivering liquid continuously over a flow ranging from 0.11 µL/min to 4.84 µL/min. This micropump demonstrates a maximum cumulative released drug volume of up to 100.8 µL and was able to produce a pressure that is higher than the intraocular pressure. The results can be used for the study of age-related macular degeneration, diabetic retinopathy, and other ophthalmic diseases.
