This paper studies Zhu Xi's critical comprehension about the theories of gewu zhizhi of senior Confucian scholars, focusing on the Daxue Zhangju, Daxue huowen, and Daxue huowen yulei of Zhuzi yulei. Zhu Xi described in depth the theory of gewu zhizhi of Sima Guang, disciples of the Cheng Yi(Lu Dalin, Xie Liangzuo, Yin Ch'un, Yang Shi), scholars of Hu-Xing province(Hu An-guo, Hu hong), Li Dong in the Daxue huowen and Daxue huowen yulei, by his understanding through a criticism of the theory of gewu zhizh, thereby formulating a theory of gewu zhizhi on the basis of Cheng Yi's theory. Through this criticism of senior Confucian scholars, Zhu Xi explained that the theory of gewu zhizhi was departed from a positive affirmation of things. Zhu Xi claimed that the crux of gewu zhizhi was a thorough understanding like a sudden release achieved by accumulating Li of things. This plan of Zhu Xi with respect to "Supplementary Chapter on the Gewu Zhizhi" showed that the theory of gewu zhizhi which was set up by himself corresponded to the theory of Cheng Yi's, and it was based on the Confucian tradition firmly.

In this study, the Bookstore Block of Historical and Cultural Street in Kaifeng City is taken as the object, which makes analysis on the landscape color features appearing in the elements of the bookstore block landscape. Through literature, it obtains the contrast list for the landscape composite elements of the historical and cultural street. After mastering the general characteristics of architectural colors and basic analysis methods of landscape colors in the Qing Dynasty, it conducts the site survey on the landscape composition elements and colors of the bookstore block. According to the conclusion, it is found that the landscape color of bookstore block is composed of R series, PB series, Y series and achromatic (N) series, in which the overall color shows relatively high integrity. However, it exists some deficiencies in the use of colors in signs, facilities and modeling objects. Therefore, it is necessity to increase the color plan of landscape elements such as signs, modeling objects and facilities, enhance the recognition possibilities of visual information.

This study examined the factors that influence the emotional expression in comments on the hot news about the 'Restaurant Collapse in Linfen City, Shanxi Province' published in Sina Weibo.. As a result of the study, first, there were differences in emotional expression according to gender. Women expressed stronger anger, disappointment, sadness, and condemnation than men. Second, the intensity of emotional expression of users in the eastern region was significantly higher than that of users in the central and western region. Third, the greater the number of Weibo, the total number of blogs where users participated in comments and posted emotional expressions, the stronger the emotional expression was. Fourth, unauthenticated users showed stronger emotional expressions of disappointment and sadness than authenticated users. The results of this study present implications for the factors influencing emotional expression on hot news. This study is meaningful in that it can be compared with social networks such as Twitter and Facebook in the West by looking at the factors that influence emotional expression in the process of online public opinion formation in China, and also meaningful in that a big data analysis method was used in online news analysis.

Despite an impressive growth of online sales, the bricks-and-mortar bandwagon still remain high-profile in the realm of consumer channel switching behavior. Different from the existing research exploring the consumer switching behavior from the offline to the online retailer, this study is an effort to investigate why and when do consumers switch from the online to the offline channel by applying the push-pull-mooring framework. Thus, structural equation modeling and SPSS were used to test the established hypotheses. The results, as expected, show that both push factors (i.e., perceived risk and dissatisfaction) and pull factors (alternative attractiveness and perceived ownership) are positively related to a consumer's intention to switch from the online to the offline channel. Moreover, all of expected interactions between push factors and mooring factors (i.e., switching costs, variety seeking, and subjective norms), and between pull factors and mooring factors are supported, except for the interactions between push factors and switching costs as well as between pull factors and subjective norms. Finally, implications and limitations are discussed.

In this paper, we suggest the Deep Neural Network Model System for predicting results of the match of 'League of Legends (LOL).' The model utilized approximately 26,000 matches of the LOL game and Keras of Tensorflow. It performed an accuracy of 93.75% without overfitting disadvantage in predicting the '2020 League of Legends Worlds Championship' utilizing the real data in the middle of the game. It employed functions of Sigmoid, Relu and Logcosh, for better performance. The experiments found that the four variables largely affected the accuracy of predicting the match --- 'Dragon Gap', 'Level Gap', 'Blue Rift Heralds', and 'Tower Kills Gap,' and ordinary users can also use the model to help develop game strategies by focusing on four elements. Furthermore, the model can be applied to predicting the match of E-sports professional leagues around the world and to the useful training indicators for professional teams, contributing to vitalization of E-sports.

In order to study the role of legato to singers in vocal music performance, this paper adopts the methods of demonstration and induction and comparison to analyze the three factors affecting the creation of legato in performance and propose solutions. When thinking about the influence of singing skills on legato, singers will be able to solve such issues as breathing, articulation and vocal register, thus improving their singing skills. When thinking about the influence of singing language on legato, singers will make an in-depth study on the phonetic and structural features of the language to reach legato in language, thus promoting the in-depth study of singers on the singing language. When thinking about the influence of singing emotion on legato, singers will solve the problem of emotional coherence from two aspects of thought and emotion to create legato of emotion, thus promoting the expression of singers' emotion in the work. Obviously, legato plays an important role in improving singers' singing skills, singing language and singing emotion. The aim of the paper is to encourage singers to further deepen their attention to legato in vocal music performance and make better use of legato in singing.

There are two major factors of degrading the performance in the forward link of DS/CDMA systems. One is the multiple access interference (MAI) caused by using the same frequency bands simultaneously and the other is the multipath lading due to multipath propagation. PN codes which have minimum cross correlation properties among spread spectrum codes are necessary to reduce the MAI. In the conventional IS-95A system, the PN sequence has the period of $2^{15}$ and is of the length of 64 chips for spreading each data. In this case, since the length of PN code per bit is very short compared to the period of the PN code, the performance of the conventional system is not satisfied in view of suppressing the multipath interference. However, the correlation property of the PN codes at the demodulation can be improved by increasing the interval of Integration at the demodulation. This paper proposes a demodulation method to reduce the cross correlation among PN codes. The performance of the proposed demodulation method is investigated through computer simulations. We used multipath Ray lading channel and AWGN channel in the simulation. Our simulation results show the improved performance of $0.25{\sim}0.5dB$ SNR in a given BER compared to the conventional demodulation scheme.

MAI (multiple aperture SAR interferometry) method has been recently developed to improve the measurement accuracy of along-track surface deformation. By means of split-beam SAR processing, this novel technique produces forward- and backward-looking interferograms, which are combined to generate an MAI interferogram. The along-track surface deformation can then be derived from the MAI interferogram. The achieved accuracy of the along-track surface deformation is approximately 8 cm for interferograms with a coherence of 0.6. It is commonly recognized that the topographic phase on an MAI interferogram can be ignored. However, in this paper, we have generated an MAI interferogram from an ALOS P ALSAR interferometric pair spanning the 2010 Haiti earthquake, and shown that the topographic phase distortion on the MAI interferogram can reach to about $3.45{\times}10^{-4}$ rad./m. This distortion corresponds to an along-track surface deformation of about 98 cm. We have proposed an efficient method to remove the topographic phase distortion. After correcting the distortion, the topographic phase distortion on the MAI interferogram is reduced to about $7.82{\times}10^{-6}$ rad./m. This means that the proposed method can effectively remove the topographic distortion on the MAI interferogram to improve along-track surface deformation measurement.

Utilization of synthetic benzyladenine (BA) for bean sprout production should be reduced or minimized because of elevating production cost and not ascertaining action mechanism to human body. The study was done to compare the effects of BA concentrations under different watering methods (overspraying or underwatering) on growth and morphological characteristics of mungbean sprouts. Seeds of cv. Zhong-Lu 1 were soaked for 5 hours in the solutions with different BA concentrations (0, 10, 20, 30, 40, 50 ppm) before 4 hour aeration, and then were cultured for 6 days by both watering systems. Their morphological characters, fresh and dry weights were measured. Regardless of watering methods, lateral roots were sharply dropped over 30 ppm BA concentrations, and hypocotyl, root and total lengths were shortened with increased BA concentrations although ratios of hypocotyl to root lengths and hypocotyl diameters were enlarged with their increment. Total fresh weights were increased up to 20 ppm in overspraying method but up to 30 ppm in underwatering method mainly due to increment of hypocotyl fresh weights. The sprouts were faster grown in overspraying method than in underwatering method because the former showed longer lengths of hypocotyl and root, and total fresh weights.

Caliper measurements of tumor volume have been widely used in the assessment of tumors in animal models. However, experiments based on caliper data have resulted in unreliable estimates of tumor growth, due to necrotic areas of tumor mass. To overcome this systematic bias, we engineered a new luciferase-expressing rat prostate cancer cell line (MLL-Luc) that produces bioluminescence from viable cancer cells. MLL-Luc cells showed a strong correlation between bioluminescence intensity and cell number ($R^2$=0.99) and also accurately quantified tumor growth, with reduced bioluminescence signals caused by necrotic cells in a subcutaneous MLL-Luc xenograft model. The accurate quantification of tumor growth with bioluminescence imaging (BLI) was confirmed by a better antitumor effect of combination chemotherapy, compared to that based on caliper measurements with a correlation between the bioluminescence signal and tumor volume ($R^2$=0.84). These data suggest that bioluminescent MLL xenografts are a powerful and quantitative tool for monitoring tumor growth and are useful in evaluating the efficacy of anticancer drugs, with less systematic bias.
