Automated Stratum Interface Detection Using the Optimized Drilling Specific Energy through Self-Adaptive Logistic Function.

The precise detection of stratum interfaces holds significant importance in geological discontinuity recognition and roadway support optimization. In this study, the model for locating rock interfaces through change point detection was proposed, and a drilling test on composite strength mortar specimens was conducted. With the logistic function and the particle swarm optimization algorithm, the drilling specific energy was modulated to detect the stratum interface. The results indicate that the drilling specific energy after the modulation of the logistic function showed a good anti-interference quality under stable drilling and sensitivity under interface drilling, and its average recognition error was 2.83 mm, which was lower than the error of 6.56 mm before modulation. The particle swarm optimization algorithm facilitated the adaptive matching of drive parameters to drilling data features, yielding a substantial 50.88% decrease in the recognition error rate. This study contributes to enhancing the perception accuracy of stratum interfaces and eliminating the potential danger of roof collapse.

[Briefs of Japanese acupuncture-moxibustion works of Chinese translation version in modern times].

The authors collected 25 Japanese acupuncture-moxibustion works of Chinese translation version in modern times (1912-1960) and investigated them from 3 aspects, named the study on the mechanisms of acupuncture and moxibustion, the explanation of basic theory and clinical treatment with acupuncture and moxibustion. Generally speaking, Japanese acupuncture-moxibustion works of Chinese translation version explained the mechanisms of acupuncture and moxibustion in terms of the theory of western medicine rather than traditional one. It proposed the study on the phenomenon of meridian and collateral, which absorbed the anatomic knowledge of western medicine in the discussion on meridians, collaterals and acupoints; introduced diagnostic methods and techniques of acupuncture and moxibustion and adopted the classification of western medicine system and the diseases in western medicine to discuss the treatment with acupuncture and moxibustion. All of these reflect the academic characteristics of acupuncture and moxibustion in Japan at those times and the position of Chinese scholars, by which the Japanese medical works were introduced for the academic innovation.

[Impact of Japanese Medical Acupuncture Literature Introduced Before 1949 on Development of Chinese Acupuncture-moxibustion].

The literature of Japanese medical acupuncture introduced before 1949 has a definite impact on Chinese acupuncture and moxibustion in the period of Republic of China and the early period of the establishment of the People's Republic of China. In the present paper, the authors introduce its impact from: 1) Chinese medical works on acupuncture and moxibustion absorbed a lot of western medicine knowledge, and interpreted some underlying mechanisms chiefly according to the theory of nerve, blood and endocrine, including the meridian-collateral theory based on the structures of blood vessels, lymph vessels, nerves, etc.; 2) In some Chinese clinical books, some Japanese new techniques as "tube-needling" (sparrow-pecking needling, etc.) were introduced, the acupuncture treatment of disorders was discussed from the nomenclature of western medicine and some operative standards (dissection of acupuncture needles, etc.) in clinical practice were accepted; 3) Some western medicine courses, and subject settings were introduced in Chinese acupuncture education. In general, Japanese acupuncture literature introduced before 1949 promotes integration of traditional acupuncture theory and western medicine in the early period of new China, enriches practical techniques in clinical practice and accelerates the development of acupuncture education in some way.
