[quick news] on May 17, 2019, the teacher "threw the paper" and hit the academic management pain point, reading the painstaking behind the teacher's "gaffe"

Recently, a teacher severely criticized the students on the stage and threw the paper at the students at the scene of a college graduate's oral defense in Guangdong Province According to common sense, the teacher's behavior is somewhat "rough" However, the network comments are "one-sided" on the side of teachers, and everyone confirms the strict attitude of teachers and criticizes students' papers for being too "water" The content and level of these students' papers have not been reported However, the school confirmed that the reason why the teacher threw the paper was that the students were not prepared enough for the defense The thesis thrown by Guangdong teacher is not only the pain point of current undergraduate thesis quality, but also the weakness of undergraduate thesis management system This also reminds us that the key point of graduation thesis management should be further moved forward, and the responsibilities of each key point should be further compacted Only by repeatedly "dunmiao" at different levels can the paper not be "thrown" to the platform at the last moment Only in this way can the paper become a proof of students' ability to go to the society, or a solid step to continue their academic career Http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-05 / 17 / content_ HTM? Div = - 1 The nature index supplement shows the highest growth rate of medical research output in China The nature index 2019 - biomedicine, published on the 16th, shows the high-quality research output of global research institutions, universities and medical institutions in the biomedical field According to the natural index data, the United States is a global leader in biomedical field, while China is catching up with it, and the related scientific research output is increasing rapidly In addition, scientific research activities in this field are increasingly showing the trend of international cooperation According to the supplement, the U.S has invested more in biomedical research than any other country in the world Although fund support and high-quality research output in this field have declined, they are now in the absolute leading position in the world From 2012 to 2018, China's natural index biomedical research output ranked second in the world, but the growth rate was over 140%, far exceeding other leading countries Http://news.scienceet.cn/htmlnews/2019/5/426342.shtm is surrounded by "black technology" Which products of the world intelligent Congress let you "plant grass"? On June 16, the third world intelligent conference opened in Tianjin, focusing on the new development and opportunities brought by intelligent technology Many participating enterprises brought their latest technology products one after another, and the audience was immediately "surrounded" by the strong intelligent technology wind on site The most attractive ones include: 5g remote driving, "voice on song" headset, intelligent health "magic mirror" and classroom expression recognition 5g remote driving technology relies on the characteristics of 5g network, such as large bandwidth and low time delay It is mainly used in unmanned driving or remote driving scenarios, such as remote takeover of vehicles, special area operations, rescue and disaster relief The "voice on demand" headset relies on the two "intelligent music recognition" functions of the audio fingerprint technology, i.e "listening to songs" and "humming to recognize songs", to retrieve the "forgotten" songs This technology makes it more convenient and cool for people to listen to songs on mobile phones which are common in leisure, work, study or travel Intelligent health "magic mirror" is not only a simple dressing mirror, but also one end of smart home It can be used as display screen, player, display image, voice and other information At the same time, through wireless network, it also communicates data with other intelligent wearable devices, and establishes a perfect personal body monitoring system, which can broadcast the body in real time through touch screen and voice interaction Body monitoring information Classroom expression recognition is a kind of classroom intelligent comprehensive evaluation system, which can use the camera and related programs to judge the micro expression of students in the classroom, so as to grade their classroom activity, concentration and thinking Http://www.xinhuanet.com/tech/2019-05/16/c_.htm adding metal to old tires can easily degrade antibiotic wastewater Zhang Yongjun research group of Nanjing University of technology used waste tires as raw materials and copper and cerium as active components for loading, made a new type of high-efficiency carbon catalyst for copper and cerium tires, which can rapidly degrade ofloxacin, realize resource utilization and waste treatment The results were published online in the new top environmental journal application catalysis B "Using copper and cerium as active components and loading them on tire carbon to prepare catalyst is one of our biggest innovations." Yu Yang, a researcher of the research group, said that copper and cerium bimetallic can greatly improve the catalytic activity and stability Copper cerium tire carbon catalyst adopts persulfate oxidation system, which has high redox potential, is convenient and stable, and can degrade most organic substances into carbon dioxide and water The results have important reference value for the development and preparation of low-cost and high-efficiency heterogeneous catalysts The mechanism of bimetallic activation of persulfate is clarified, which has guiding significance for the further development of persulfate oxidation system At the same time, it provides a new way for the reuse of waste tires, and also provides a new solution for the treatment of refractory organic pollutants, realizing the "waste treatment" Https://www.sciencedirect.com/science/article/pii/s092637319303698 "artifact" of diabetes screening can foresee the next six seconds, and detect the accumulation level of advanced glycation end products (ages) in the lens of human eyes, so as to realize non-invasive screening of diabetes risk At the same time, we can collect a large number of clinical big data by the way, establish a diabetes risk assessment model, and accurately predict the risk of diabetes in the future At the 81st China international medical device (spring) Expo in Shanghai, sannuo biology, from Changsha, Hunan Province, has officially released a new "artifact" for non-invasive screening of diabetes risk, agescan advanced glycation end product fluorescence detector, which is jointly developed by US scientists Agescan detection is to emit a blue light which is safe for human body through the blue light led to irradiate the left lens of the subject The final product of advanced glycosylation in the crystal body will produce fluorescence after being excited, and will be "captured" by the instrument According to the positive correlation between the fluorescence intensity and the accumulation level of glycosylation end products, the risk screening of diabetes can be achieved This method not only improves the detection accuracy and detection rate, but also has the advantages of non-invasive, no blood drawing, no reagent, reduces the risk of consumables and infection, and greatly reduces the workload of medical staff At the same time, the advantage of its test not affected by blood sugar fluctuation also saved the subjects from having to suffer from starvation and fasting for the test http://digitalpaper.stdaily.com/http_www.kjrb.com/kjrb/html/2019-05/17/content_421348.htm?div=-1
