Chinese civilization has always been called "rites and music civilization"(li-yue-wen-ming ). It is also the due meaning of sacred education to educate the people and change customs with rites and music. Chinese sage education aims to cultivate benevolent gentlemen with five constant virtues, which are based on benevolence, and this benevolence is embodied in the civilization of rites and music in Chinese society. It is precisely because of "the substance and function relationship"(ti-yong-guan-xi ) between benevolence and "the system of rites and music"(li-yue-zhi-du ) that Zhu Zi's Xiao Xue education pays particular attention to cultivating gentlemen with ideal personality through rites and music education.

Recently, sulfonamides have been shown to be promising electrolyte components due to their high chemical and electrochemical stability in lithium batteries [1, 2]. The electrolyte stability becomes critical when applying high voltage and/or utilizing Ni-rich layered oxides in high energy density lithium-ion batteries. Another approach to successful Ni-rich cathode performance is to develop a stable and effective cathode electrolyte interphase (CEI). Given the success of sultones and sulfates in this regard [3, 4], it is hypothesized that nitrogen analogs, like sulfonamides, could be tailored to provide a similar benefit. Indeed, Yim et al. [5, 6] have shown that N,N,N’,N’-tetraethylsulfamide (TES) forms a CEI on NMC811 that imparts high voltage cycling stability and less cathode corrosion. Our earlier studies of TES with Ni-rich NCA also formed a favorable CEI and these results are the topic of this presentation. Herein, we examine the performance of 0 - 4 wt.% TES in our commercially available, high power INR18650-P28A. These cells contain a composite SiO/graphite anode in addition to a Ni-rich cathode. As shown in Fig 1, TES significantly decreased the impedance of the cathode interface after conditioning compared to the control electrolyte. Thereafter, cells containing up to 2%TES show improved capacity retention during long-term high-rate cycling (+1C/-80W). Part of this success was due to a suppression of resistance growth during cycling by TES. Fast charge cycling (+3C/-2C), however, was moderately impaired with increased TES. Considering the largely reduced impedance of the cathode, fast-charge performance may have suffered due to anode rate limitations. These results will be discussed as well as gas generation, storage performance, and additional rate and cycling tests. [1] Shuting Feng, Mingjun Huang, Jessica R.

Molecular crowding electrolyte was proposed to improve the stability of water at a low concentration of Li salt (2 m LiTFSI )1. Low-cost and safe poly (ethylene glycol) (PEG, Mn=400) is adopted as a crowding agent to confine water molecules through hydrogen bonding and strengthen the covalent bond of H-O (H2O), leading to effective suppression of water decomposition (especially HER). However, the mechanism behind the improved cathodic stability of molecular crowding electrolyte is not yet fully understood. Specifically, the composition of the SEI and the impact of salt on the electrochemical stability of PEG-based electrolyte are still unknown. To gain a deeper insight into the stability mechanism in molecular crowding electrolytes, we investigated the cathodic stability of PEG-based molecular crowding electrolytes with LiTFSI and LiClO4 as the electrolyte salt. We characterized the composition and structure of SEI on Li4Ti5O12 electrode (LTO) derived from LiTFSI- and LiClO4-containing electrolytes, and correlated cathodic stability to the composition of the SEI. Comprehensive characterizations including linear sweep voltammetry (LSV), online electrochemical mass spectroscopy (OEMS), X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) are used to study the cathodic stability of water. The enhance mechanism will be discussed. [1] Xie, J., Liang, Z. & Lu, Y. C. Molecular crowding electrolytes for high-voltage aqueous batteries. Nat.

Abstract Background: Morpho-physiological alternations of platelets provided a rationale to harness RNA sequencing of tumor-educated platelets (TEPs) for preoperative diagnosis of cancer. Timely, accurate, and non-invasive detection of ovarian cancer in women with adnexal masses presents a significant clinical challenge. Patients and Methods: This intercontinental, hospital-based, diagnostic study included 761 treatment-naïve inpatients with histologically confirmed adnexal masses and 167 healthy controls from nine medical centers (China, n=3; Netherlands, n=5; Poland, n=1) between September 2016 and May 2019. The main outcomes were the performance of TEPs and their combination with CA125 in two Chinese (VC1 and VC2) and the European (VC3) validation cohorts collectively and independently. Exploratory outcome was the value of TEPs in public pan-cancer platelet transcriptome datasets. Results: The AUCs for TEPs in the combined validation cohort, VC1, VC2, and VC3 were 0.918 (95% CI 0.889-0.948), 0.923 (0.855-0.990), 0.918 (0.872-0.963), and 0.887 (0.813-0.960), respectively. Combination of TEPs and CA125 demonstrated an AUC of 0.922 (0.889-0.955) in the combined validation cohort; 0.955 (0.912-0.997) in VC1; 0.939 (0.901-0.977) in VC2; 0.917 (0.824-1.000) in VC3. For subgroup analysis, TEPs exhibited an AUC of 0.858, 0.859, and 0.920 to detect early-stage, borderline, non-epithelial diseases and 0.899 to discriminate ovarian cancer from endometriosis. Analysis of public datasets suggested that TEPs had potential to detect multiple malignancies (Table 1). Conclusions: TEPs had robustness, compatibility, and universality for preoperative diagnosis of ovarian cancer since it withstood validations in populations of different ethnicities, heterogeneous histological subtypes, early-stage ovarian cancer as well as other malignancies. However, these observations warrant prospective validations in a larger population before clinical utilities. Table 1. Performance for TEPs in public pan-cancer datasets.

Aqueous rechargeable batteries (ARB) arose considerable interest for stationary energy storage due to low cost, inherent safety, and environmental friendliness.[1] Besides aqueous lithium-ion batteries, various kinds of aqueous batteries have been proposed, utilizing relatively inexpensive charge carriers either based on metal (Na+, K+, Ca2+, Mg2+, Zn2+, Al3+, etc.) or non-metal cations (H3O+, NH4 + etc.).[2] Among non-metallic ion batteries, aqueous ammonium-ion batteries (AAIBs) distinguish themselves by working in near neutral or mild acidic environment, refraining from severe electrode corrosion.[3] However, like other ARB systems, the energy density of AAIBs is limited by the narrow electrochemical stability window of the aqueous electrolyte. In addition, NH4 + ions hydrolyse in water resulting in decreased pH of the electrolyte which promotes the hydrogen evolution reaction (HER).[3] This means that increasing salt concentration may not be an effective strategy to enlarge the stability window of the electrolyte. In fact, according to a previous report, the cathodic stability of 25 m ammonium acetate (NH4Ac) is even slightly inferior than that of 1 M NH4Ac.[4] Developing alternative strategies to inhibit HER in diluted electrolytes is of uttermost importance. In diluted aqueous electrolytes, the continuous and complicated H bond network among water molecules favours fast ionic motion but also causes severe HER. Here, we propose ethylene glycol (EG) as electrolyte component to manipulate the H bond structure in diluted (1 m) NH4Ac solutions. FTIR results are used to study the H-bonding network as function of the EG:water ratio. The diluted aqueous electrolyte containing EG show no freezing point and wider electrochemical window. As a proof-of-concept, full cells composed of Prussian blue derivatives, PTCDI anode, and 1 m NH4Ac with the addition of EG are tested to verify the effectiveness of EG during battery operation. Improved cycling performance and higher coulombic efficiencies are demonstrated compared to those including 1 m NH4Ac in water.

COVID-19 Pandemic resulted in social mobility and travel restrictions to contain the infection. It has been reported that there happened post-pandemic surge in the use of the internet and social media as people rely on it more often for entertainment, work, and learning purposes. It is also been used as an unhealthy coping strategy for pandemic related stress. The smartphone was found to be the most common gadget used for accessing internet-based services. Owing to the postural alterations related to the small screen size of smartphones, neck pain was reported very commonly among smartphone users. Neck pain among smartphone users is a public health concern needing immediate attention in the pandemic time. Many of the risk factors leading to neck pain among smartphone users are modifiable. The authors outline preventive strategies that are mostly self- regulated. The strategies recommended include reducing Smartphone usage time (Smartphone-Free Time, Smartphone-Free Zone), maintaining ideal posture (Focus Breaks, Mobility Breaks, How am I keeping my posture?, Hands-free alternatives), doing regular exercises, preparing and following an activity schedule, and inculcating healthy habits.

Underwater acoustic signature identification has been employed as a technique for detecting underwater vehicles, such as in anti-submarine warfare or harbour security systems. The underwater sound channel, however, has interference due to spatial variations in topography or sea state conditions and temporal variations in water column properties, which cause multipath and scattering in acoustic propagation. Thus, acoustic data quality control can be very challenging. One of challenges for an identification system is how to recognise the same target signature from measurements under different temporal and spatial settings. This paper deals with the above challenges by establishing an identification system composed of feature extraction, classification algorithms, and feature selection with two approaches to recognise the target signature of underwater radiated noise from a research vessel, Ocean Researcher III, with a bottom mounted hydrophone in five cruises in 2016 and 2017. The fundamental frequency and its power spectral density are known as significant features for classification. In feature extraction, we extract the features before deciding which is more significant from the two aforementioned features. The first approach utilises Polynomial Regression (PR) classifiers and feature selection by Taguchi method and analysis of variance under a different combination of factors and levels. The second approach utilises Radial Basis Function Neural Network (RBFNN) selecting the optimised parameters of classifier via genetic algorithm. The real-time classifier of PR model is robust and superior to the RBFNN model in this paper. This suggests that the Automatic Identification System for Vehicles using Acoustic Signature developed here can be carried out by utilising harmonic frequency features extracted from unmasking the frequency bandwidth for ship noises and proves that feature extraction is appropriate for our targets.

In the Reform Proposals for the Education in Hong Kong published in 2000, it was clearly stated that the priotity of education in the 21st century should be ―to enable our students to enjoy learning, enhance their effectiveness in communication and develop their creativity and sense of commitment‖. This paper aims to respond to two of the aspects — the enhancement of effectiveness in communication and the development of students’ creativity. For years, schools have focused on promoting students’ creavity in reading and writing, but not in speaking. In fact, among the various language skills, ‘speaking’ is the skill students have to demonstrate the most in their daily interaction. Compared to reading and writing, the ability to express one‘s views verbally in a creative manner can give rise to more direct interaction, acting as a genuine reflection of a student’s wisdom, knowledge, capability and potential. It is also a lifelong skill that students can apply when they join the workforce in the future. It is therefore meaningful to place emphasis on cultivating students’ creativity in speaking. This research aims to explore the correlation between the Chinese oral proficiency and creative ability of senior secondary students in Hong Kong based on existing theories on the development of creativity and speaking. Target participants, recruited from two aided secondary schools of different abilities, receive training on speaking and creative thinking, and analysis is done adopting both the quantitative and qualitative approaches. Students of each school are first randomly divided into two groups — the experimental group and control group. Students of both groups are required to take a pre-test and a post-test, as well as complete a set of questionnaire in each session. Results obtained are compared and contrasted to gauge the changes in their oral proficiency and creative ability. In between the tests, the experiemental group receives seven experimental design lectures on News and Report, one of the elective modules of the NSS curriculum in Chinese Language Education, while the control group receives lectures on News and Report which reference on the samples from Education Bureau only, no experimental design lectures will be delivered. In the end, the three teachers involved in the study were interviewed, during which the teachers offered their observations on the change in the students’ learning behaviour and attitude. Based on the data collected from the administration of tests, questionnaires and interviews, the following conclusions are made: first, there is a correlation between oral proficiency and creative ability; second, students’ attitude and values have a direct impact on the effectiveness of the module; third, the Speaking and Creativity Assessment rubric used in the study proved to be successful in assessing the said abilities, enhancing learning effectiveness. Through the analysis of data collected, this research contributed to Chinese Language Education to some extent, especially in the teaching of oral proficiency and creativity. It opened up a new set of criteria for the assessment of creative speaking ability from different perspectives to ensure objectivity of results, offered diversified course materials that can effectively raise the standard of students’ speaking and critical thinking ability. 香港在2000 年教育制度改革建議中明確指出教育首要目標是培養學生成為「樂於學習、善於溝通、勇於承擔、敢於創新」的新一代，其中，本研究特別回應「善於溝通」和「敢於創新」這兩個重點。過往，學校及教師多注重學生閱讀能力及寫作能力創意的培養，而忽略說話能力的創意訓練。其實，在各種語文能力中，「說話」是學生日常生活最主要的表達能力。口語表達比閱讀及寫作語言起著更直接的交流及溝通作用，是一個人智慧、知識、能力、素質的綜合體現，是學生立足社會、終生受用的語文能力。因此語文教學以創意思維培養學生的說話能力是有實在意義的。 為探索本港高中學生口語表達和創意能力的相互關係，本研究以創造力(Creativity) 和說話能力訓練的理論為依據，對上述課題展開試驗及分析工作。本計劃以香港兩所不同程度的津貼中學學生的說話能力為研究對象， 施行融合創意和說話能力訓練的實驗教學模式。本研究採用量化和質化方式為主要研究的方法。首先， 每所學校的研究對象隨機分為實驗組 (Experimental Group) 和控制組 (Control Group)。兩組對象分別安排前測和後測來量度實驗前後的數據變化。在前測及後測之間， 實驗組將會進行結合了創意思維訓練元素的中國語文選修單元「新聞與報道」共七節課的教學，從而探究這次實驗課能否提高學生創意說話能力學習的成效。而控制組卻不會在實驗教學施行期間安排進行任何實驗教學，有關的課堂教學，只按照原本學校的「新聞與報道」課程進行。在公平的原則下，所有控制組的學生會在暑假補回教授有關的實驗課程知識。本研究同時在兩班實驗組學生發出前後兩次的問卷調查，以檢視受試者的說話能力及創意能力的變化。最後，訪問兩所受試學校參與研究的三位老師，以深入瞭解學生整體的學習行為和態度情意的改變。 透過分析實驗教學資料、問卷調查數據和訪談結果，本研究主要有以下幾方面的總結：第一，確立說話能力和創意能力的相互關係。第二，學生的學習態度和品德情意直接影響課程的學習成效。第三，本研究所採用的「說話及創意能力評量表」能客觀評估學生的說話及創意能力，促進學習效能。經各種測試及結果分析，本研究對中國語文教育作出了一些貢獻，尤其是在融合說話與創意能力方面，以提高學生說話和思考水平；開發創意說話能力的評核標準，包含多角度的評審考量為評核精神，以客觀的等級描述為評量依據；提供多元化的創意說話課程設計，有助提升學生的創意說話能力表現等多方面的意義。

近年來，香港有不少國際學校和直資學校開辦國際文憑課程（IB，International Baccalaureate），很多非華語學生選擇學習中文作為第二語言。然而，當中很多學生在使用詞彙上產生偏誤，而在二零零八年，香港教育局發布了《中國語文課程補充指引（非華語學生）》諮詢文件中，指出漢字的字形、聲調、語彙都是中文第二語言學習者的難點（香港課程發展議會，2008），這些難點均涉及語素。以往曾有不少研究，探討語素意識與詞彙知識習得的關係，因此，研究者期望以中文第二語言學習者作為研究對象，探討漢語語素意識與詞彙能力的關係。 本研究為量性研究，以語素意識與詞彙能力測驗和單元評估試卷來蒐集數據，並採用相關度測量研究方法分析數據，從而探討國際文憑課程中學項目學生在詞彙上的偏誤類型以及漢語語素意識與詞彙能力的關係，並提出建議以提升中文第二語言學習者的詞彙能力。本研究目的有三：（一）探究香港國際文憑課程中學項目學生在詞彙上的偏誤類型；（二）探究香港國際文憑課程中學項目學生的漢語語素意識與詞彙能力的關係；（三）歸納研究結果，並就教學和後續研究上提出具體建議，作為對外漢語教學之參考。 研究結果顯示，中文第二語言學習者的詞彙偏誤類型以「語音」為主，發展同音語素意識對於減少詞彙偏誤相當重要，此外亦需要加強發展部件規則的意識以及組字規則的概念，幫助他們掌握字形，對於減少詞彙偏誤亦有相當重要的作用。在漢語語素意識與詞彙能力的關係方面，中文第二語言學習者的語素意識對於詞彙能力有預測作用，同音語素意識對詞彙能力的預測作用大於同形語素意識的作用；而心理詞彙的語素意識、心理詞彙的數量及用詞能力三者有互相影響的關係，但仍需要進一步的研究。 International Baccalaureate (IB) Curriculum is adopted by more and more international schools and direct-subsidy schools in Hong Kong. At the same time, more and more non-Chinese speaking (NCS) students choose to study Chinese Language as a second language in IB curriculum. However, the vocabulary learning is one of the difficulties when they learn Chinese. The Education Bureau has published ‘Consultation Paper on Developing a “Supplementary Guide to the Chinese Language Curriculum for Non-Chinese Speaking Students” ’ and points out those NCS students encounter difficulties in learning Chinese graphemes, tones, vocabulary, etc. These difficulties are related to morpheme. Many researchers have conducted to study on relationship between morphological awareness and lexical knowledge. This dissertation aims to study on the relationship between morphological awareness and lexical ability of IB Middle Year Programme (MYP) students in Hong Kong. This is a quantitative research. Data collection includes two tests of the morphological awareness and lexical ability paper-pencil tests and one summative unit test of Chinese Language subject in a school. IB MYP students of two classes participated in this study and their morphological awareness and lexical ability were tested and analyzed by the statistical analysis software. The objectives of the study are: (1) Analysis on the types of lexicon errors of IB MYP students in Hong Kong; (2) Analysis on the relationship between morphological awareness and lexical ability of IB MYP students in Hong Kong; (3) Suggestions on developing of morphological awareness in learning Chinese Language as a second language. The results find that most of the lexicon errors were related to the tones and radical components of Chinese character, it is suggested to develop the homophone awareness and the orthographic awareness of Chinese character to reduce the lexicon errors. The morphological awareness of students has influence on student’s lexical ability. The homophone awareness has a closer relationship with lexical ability. The morphological awareness of the mental lexicon has an influence on the amount of mental lexicon and the ability of using lexicon. It is suggested to develop the morphological awareness of students in teaching Chinese as a second language to further study the relationship between the development of morphological awareness and mental lexicon in the future.
