    Abstract This paper analyzes the motivations of the British biochemist Joseph Needham for participating in 'the International Scientific Commission for the Investigation of the Facts Concerning Bacterial Warfare in Korea and China (ISC)' and his major roles within it during the Korean War. Needham stayed in China for four years starting in 1942 as a scientific counselor and director of the British Scientific Mission in China, which enabled him to interact with many Chinese scientists and politicians. Surprisingly, during this period (1944), Needham conducted an investigation into the Japanese military's use of bacterial warfare. Through his personal records, Needham repeatedly stated that his experience with bacterial warfare research in 1944 was one of the most important reasons for his participation in ISC activities. In addition, Needham secretly but very actively sought to recruit other investigators within Britain. Needham repeatedly tried to persuade fellow professors at Cambridge University, William Thorpe and Vincent Wigglesworth, to be included in the investigation team. Although Needham had doubts about his own expertise in investigative activities, he actively expressed his desire to become a member of the investigative team through various channels. Primary documents show that he actively and voluntarily led the investigation activities after joining the team in professional discussions, document analysis, and witness interrogations. Needham's passion and sincerity demonstrated in internal meeting minutes dispel some misunderstandings that the investigation team's activities were limited to passively approving Chinese data.

    Abstract In 1946, the U.S. Army established the 406th Medical General Laboratory as the central medical research institute for their new Asia-Pacific-occupied area. The primary mission of the 406th medical laboratory was to supplement the epidemiologic, sanitary, and diagnostic services available in other medical facilities and hospitals, and to investigate outbreaks of disease and conditions which affect or may affect the health of the people in the occupied area. At the time of its establishment, the 406th laboratory had considerable difficulties securing researchers, but it solved the related problems by actively cooperating with Japanese medical researchers and research institutes. According to the statistics in 1947, the 406th laboratory consisted of 46% of its total research personnel, Japanese researchers. The 406th medical laboratory's professional research departments included the department of Pathology, Serology, Bacteriology, Medical Zoology, Chemistry, Virus and Ricketts, Entomology (established in 1949), and Epidemiology (established in 1951). All research departments played a central role in the Asia-Pacific region in their professional fields. For example, the department of Pathology functioned as the "histopathology center of all hospitals in Japan, Korea, and the Mariana-Bonin Command" under the provision of "Army Regulation 40-410," and the department of Chemistry was called an "analytical chemistry laboratory for the Far East Command" because it performed various chemical experiments for many medical facilities in the area with insufficient research facilities.

    Abstract Pulse diagnosis has remained underexamined in medical anthropology, despite the potential of ethnographic investigation to enrich and enliven the discussion of the tactility-centered practice and its associated issues of experience, language, and the body. By capturing boundary-crossing interactions between the diagnosing and diagnosed, experience and expression, and activity and passivity, in this article I provide ethnographic details of how East Asian tactile diagnostics operate. My argument illustrates various ways of knowing and experiencing things and beings, hitherto dominated by vision and visualization as well as the divide between active knower and fixed objects.

    Abstract The ever-increasing energy demand and global warming caused by fossil fuels push for the exploration of sustainable and eco-friendly energy sources. Waste thermal energy has been considered as one of the promising candidates for sustainable power generation as it is abundantly available everywhere in our daily lives. Recently, thermo-electrochemical cells based on the temperature-dependent redox potential have been intensely studied for efficiently harnessing low-grade waste heat. Despite considerable progress in improving thermocell performance, no attempt was made to develop electrode materials from renewable precursors. In this work, we report the synthesis of a porous carbon electrode from mandarin peel waste through carbonization and activation processes. The influence of carbonization temperature and activating agent/carbon precursor ratio on the performance of thermocell was studied to optimize the microstructure and elemental composition of electrode materials. Due to its well-developed pore structure and nitrogen doping, the mandarin peel-derived electrodes carbonized at 800 °C delivered the maximum power density. The areal power density (

    Abstract Photonic synaptic transistors are being investigated for their potential applications in neuromorphic computing and artificial vision systems. Recently, a method for establishing a synaptic effect by preventing the recombination of electron-hole pairs by forming an energy barrier with a double-layer consisting of a channel and a light absorption layer has shown effective results. We report a triple-layer device created by coating a novel electron-trapping layer between the light-absorption layer and the gate-insulating layer. Compared to the conventional double-layer photonic synaptic structure, our triple-layer device significantly reduces the recombination rate, resulting in improved performance in terms of the output photocurrent and memory characteristics. Furthermore, our photonic synaptic transistor possesses excellent synaptic properties, such as paired-pulse facilitation (PPF), short-term potentiation (STP), and long-term potentiation (LTP), and demonstrates a good response to a low operating voltage of - 0.1 mV. The low power consumption experiment shows a very low energy consumption of 0.01375 fJ per spike. These findings suggest a way to improve the performance of future neuromorphic devices and artificial vision systems.

    Abstract How do classical texts, such as Hwangdi Neijing and Shanghanlun, continuously play significant roles in medical practices in the history of East Asian medicine? Although this is a significant question in interpreting the position of written texts in the medical history and even for understanding the structure of East Asian medical knowledge, it has been conspicuously underexamined in the studies of East Asian medicine. In order to explore this underrepresented question, this study focuses on currents of tradition in contemporary South Korea. Drawing on anthropological fieldwork at three Donguibogam (Treasured Mirror of Eastern Medicine) currents, it delves into the interaction of text and practice in East Asian medicine. Even though all three currents (Hyun-dong, Byeong-in, Hyung-sang) are based on Donguibogam, their ways of reading the text and organizing clinical practices are diverse. Each current sets up a keyword, such as pulse diagnosis, cause of disease, and appearance-image, and attempts to penetrate the entire Donguibogam through the keyword. This means that the classical medical text is open to plural approaches. This study found that there is a visible gap between a medical text and the reader of the text in East Asia. Masters and currents of tradition are the actors who fill up the gap, continuously interpreting and reinterpreting classical texts, and guiding medical practices of new readers. Adding the history of practice to the body of literature that have focused on the history of written texts, this study will contribute to the history of East Asian medicine.

    Abstract The reliability instability of inhomogeneous Schottky contact behaviors of Ni/Au and Pt/Ti/Pt/Au gate contacts on AlGaN/GaN high-electron-mobility transistors (HEMTs) was investigated via off-state stress and temperature. Under the off-state stress condition, Pt/Ti/Pt/Au HEMT showed abruptly reduced reverse leakage current, which improved the Schottky barrier height (SBH) from 0.46 to 0.69 eV by suppression of the interfacial donor state. As the temperature increased, the reverse leakage current of the Pt/Ti/Pt/Au AlGaN/GaN HEMT at 308 K showed more reduction under the same off-state stress condition while that of the Ni/Au AlGaN/GaN HEMT increased. However, with temperatures exceeding 308 K under the same off-state stress conditions, the reverse leakage current of the Pt/Ti/Pt/Au AlGaN/GaN HEMT increases, which can be intensified using the inverse piezoelectric effect. Based on this phenomenon, the present work reveals the necessity for analyzing the concurrent SBH and reliability instability due to the interfacial trap states of the MS contacts.
