Needham Problem(NP) is the influential question that English historian of Chinese science Joseph Needham raised, "Why modern science had not developed in the Chinese civilisation but only in that of Europe?" Our objectives in this paper are as follows: First, we will revisit NP in the broad context of the emergence of modernity rather than treating it just as an internal problem of Chinese science. After that, the problem of modernity in Chinese medicine will be discussed from the viewpoint of NP. After NP's intellectual backgrounds are summarized, its value and implications are examined, and then Needham's own answers are presented. Afterwards, we present supplementary hypotheses, adapted from Weber, as our solution to NP in Chinese science and medicine. Needham thought that the European scientific revolution would not have been possible without the rise of modern capitalism. He also believed that Chinese bureaucratism facilitated early development of Chinese science and in turn, inhibited later radical change by interrupting the rise of capitalism. According to our hypotheses, scientific changes are related to social changes, especially to the legitimation crises, which lead to the alternations of mode of justification in sciences. The Chinese society did not go through the legitimation crises as the European society did, and therefore it failed to produce a radically different kind of justification from the traditional one. This is the reason why there was no revolution in science and medicine in China.

[6]-Gingerol is known as the major bioactive constituent of ginger. In the study, it was observed to effectively protect against ${\bullet}OH$-induced DNA damage ($IC_{50}$ $328.60{\pm}24.41{\mu}M$). Antioxidant assays indicated that [6]-gingerol could efficiently scavenge various free radicals, including ${\bullet}OH$ radical ($IC_{50}$ $70.39{\pm}1.23{\mu}M$), ${\bullet}O_2{^-}$ radical ($IC_{50}$ $228.40{\pm}9.20{\mu}M$), $DPPH{\bullet}$radical ($IC_{50}$ $27.35{\pm}1.44{\mu}M$), and $ABTS{^+}{\bullet}$radical ($IC_{50}$ $2.53{\pm}0.070{\mu}M$), and reduce $Cu^{2+}$ ion ($IC_{50}$ $11.97{\pm}0.68{\mu}M$). In order to investigate the possible mechanism, the reaction product of [6]-gingerol and $DPPH{\bullet}$ radical was further measured using HPLC combined mass spectrometry. The product showed a molecular ion peak at m/z 316 $[M+Na]^+$, and diagnostic fragment loss (m/z 28) for quinone. On this basis, it can be concluded that: (i) [6]-gingerol can effectively protect against ${\bullet}OH$-induced DNA damage; (ii) a possible mechanism for [6]-gingerol to protect against oxidative damage is ${\bullet}OH$ radical scavenging; (iii) [6]-gingerol scavenges ${\bullet}OH$ radical through hydrogen atom ($H{\bullet}$) transfer (HAT) and sequential electron (e) proton transfer (SEPT) mechanisms; and (iv) both mechanisms make [6]-gingerol be oxidized to semi-quinone or quinone forms.

Purpose: This study was designed to explore and compare the self efficacy, social support, and quality of life between middle-aged Korean and Chinese women. Methods: The sample included 430 (Korean: 220, Chinese: 210) middle-aged women. Study instruments were the Self Efficacy Scale developed by Shere et al (1982), the Social Support Scale modified and based on Interpersonal Support Evaluation List (ISEL) developed by Cohen and Hoberman (1983), and The Quality of Life Scale (SF-36) developed by Ware and Book (1981). Data were analyzed by SPSS/WIN 16 version. Results: Korean women reported more self efficacy and better quality of life than the Chinese women. The quality of life scores between middle-aged Korean and Chinese women showed a statistical significant difference. Self efficacy and quality of life scores reported by middle-aged Korean and Chinese women were below the reported standards of the instruments. In contrast to the other scores, Chinese women reported more social support than Korean women. Conclusion: The findings add to the body of literature about Chinese and Korean middle aged women. Additional research is needed to explain the differences among the two groups but the findings can inform the practicing nurse who works with these populations.

This study was conducted to understand the type of use and satisfaction of delivery food by Chinese and Korean students. In December 2019, Korean and Chinese students living in Gyeonggi Province were analyzed using SPSS. The average number of food deliveries was 1~2 times a month and used 30.7% of the Korean students and 21.8% of the Chinese students. As for how to order food for delivery, 62.2% of Korean college students took up mobile apps, and 49.0% of Chinese students took up mobile phones. In terms of satisfaction after using delivery food, Korean students scored 3.89 points for taste and 3.74 points for using a neat and convenient packaging container, while Chinese students showed the highest score of 3.69 points for past eating experiences and 3.65 points for taste. As for the factors influencing the satisfaction after using the delivered food, the food quality satisfaction (β=0.518) for Korean students and favorable menu factor (β=0.533) for Chinese students were found. Therefore, it is judged that it is necessary to continuously improve the quality, service, convenience and diversity of delivered food, and health and safety factors in order to improve the delivery patterns and satisfaction of college students.

This study was conducted to investigate the effect of Chinese artichoke powder on the physicochemical properties and the sensory characteristics of yanggaeng. According to the increasing contents of Chinese artichoke powder, the $^{\circ}Brix$ value and pH levels of yanggaeng were significantly decreased whereas the moisture contents of yanggaeng was significantly increased. The result of color measurement shown that L value of groups containing Chinese artichoke powder was lower than that of control group, but a value and b value of groups containing Chinese artichoke powder were higher. Texture measurement score in terms of cohesiveness, chewiness, and brittleness for yanggaeng were significantly decreased according to the levels of added Chinese artichoke powder content. The contents of total polyphenol, DPPH radical scavenging activity, and NSA of groups containing Chinese artichoke powder were higher than those of control group. As Chinese artichoke powder increased, antioxidative activity also became bigger. Sensory evaluation scores in terms of appearance, odor, taste, texture, and overall preference of groups with 2% and 4% of Chinese artichoke powder did not show any significantly differences when compared to the control group. Based on these findings, current study suggest that addition of 4% Chinese artichoke powder was the best substitution ratio for yanggaeng.

In order to solve the contradiction between requirements of high sampling rate for acquiring accurate energy information of pulses and large amount of data to be processed timely, the method with an algorithm to correct errors caused by reducing the sampling rate is normally used in front-end read-out system, which is conductive to extract accurate energy information from digitized waveform of pulse. The functions and effects of algorithms, which mainly include polynomial fitting with different fitting times, double exponential function fitting under different sampling modes, and integral area algorithm, are analyzed and evaluated, and some meaningful results is presented in this paper. The algorithm described in the paper has been used preliminarily in a prototype system of Positron Emission Tomography (PET) for heavy-ion cancer therapy facility.

Named Entity Recognition (NER) is used to identify entity nouns in the corpus such as Location, Person and Organization, etc. NER is also an important basic of research in various natural language fields. The processing of Chinese NER has some unique difficulties, for example, there is no obvious segmentation boundary between each Chinese character in a Chinese sentence. The Chinese NER task is often combined with Chinese word segmentation, and so on. In response to these problems, we summarize the recognition methods of Chinese NER. In this review, we first introduce the sequence labeling system and evaluation metrics of NER. Then, we divide Chinese NER methods into rule-based methods, statistics-based machine learning methods and deep learning-based methods. Subsequently, we analyze in detail the model framework based on deep learning and the typical Chinese NER methods. Finally, we put forward the current challenges and future research directions of Chinese NER technology.

A survey on the quality improvement and preference for green onion kimchi by Chinese and Japanese consumers was conducted by 30 Korean specialists in order to develop an improved green onion kimchi product. The long green onion shape, kimchi juice, seasonings, off-odor of fermented sea food, and stimulatory flavor of green onion were the main issues considered for the improvement of green onion product. Usage of the favorite ingredients of the Chinese and Japanese consumers was also suggested. The percentages of Chinese and Japanese who already knew green onion kimchi were 54.1% and 30.3%, respectively, whereas 46.8% of Chinese and 28.1% of Japanese have actually tried green onion kimchi in Korea. There was no significant difference in the preference for green onion kimchi between Chinese (3.25/5.0) and Japanese (3.17/5.0) consumers. For recommendations for improving the quality of green onion, Chinese consumers thought off-flavor, fibrous texture, and fermentation level were more significant while the Japanese considered red color, various taste, MSG content, and length of green onion. Seasoned tofu with green onion and rice were suggested as complementary foods to green onion kimchi by the Chinese and Japanese, respectively.
