Background The long-term outcome of rheumatoid arthritis (RA) patients who in clinical practice, exhibit persistent moderate disease activity (pMDA) despite treatment with biologics has not been adequately studied. Herein, we analyzed the 5-year outcome of the pMDA group and assessed for within-group heterogeneity. Methods We included longitudinally-monitored RA patients from the Hellenic Registry of Biologic Therapies with persistent (cumulative time ≥50% of a 5-year period) moderate (pMDA, 3.2<DAS28≤5.1) or remission/low (pRLDA, DAS28≤3.2) disease activity. The former was further classified into persistent lower-moderate (plMDA, DAS28<4.2) and higher-moderate (phMDA, DAS28≥4.2) subgroups. Five-year trajectories of functionality (HAQ) was the primary outcome in comparing pRLDA versus pMDA and assessing heterogeneity within the pMDA subgroups through multivariable mixed-effect regression. Results We identified 295 patients with pMDA and 90 patients with pRLDA, the former group comprising of plMDA (n=133, 45%) and phMDA (n=162, 55%). pMDA was associated with worse 5-year functionality trajectory than pRLDA (+0.27 HAQ units, CI 95% +0.22 to +0.33; p<0.0001), while the phMDA subgroup had worse 5-year functionality than plMDA (+0.26 HAQ units, CI 95% 0.18 to 0.36; p<0.0001). Importantly, higher persistent disease activity was associated with more serious adverse events (SAEs) [pRLDA: 0.2±0.48 vs pMDA: 0.5±0.96, p=0.006; plMDA: 0.32 ±0.6 vs phMDA: 0.64 ±1.16, p=0.038). Male gender (p=0.017), lower baseline DAS28 (p<0.001), HAQ improvement >0.22 (p=0.029) and lower average DAS28 during the first trimester since treatment initiation (p=0.001), independently predicted grouping into pRLDA. Conclusions In clinical practice, RA patients with pMDA while on bDMARDs have adverse long-term outcome compared to lower disease activity status, while heterogeneity exists within the pMDA group in terms of 5-year functionality and SAEs. Targeted studies to better characterize pMDA subgroups are needed, in order to assist clinicians in tailoring treatments.

Setelah itu data dianalisis menggunakan analisis miles interaktif menurut Miles Huberman. Hasil penelitiannya yaitu buku pelajaran yang digunakan kurang menarik karena banyak tulisan dan sedikit gambar yang memacu peserta didik untuk berpikir kritis; guru cenderung ceramah dan tanya jawab dalam proses pembelajaran; peserta didik dalam belajar cenderung menghafalkan daripada menguasai materi pelajaran; keterbatasan penggunaan media pembelajaran oleh guru materi pembelajaran menjadi abstrak bagi peserta didik padahal pembelajaran peserta didik sekolah dasar harus memperhatikan perkembangan cara berpikir peserta didik dari konkret ke abstrak. Inovasi pembelajaran yang sesuai dengan karakteristik peserta didik sekolah dasar akan mampu menciptakan pembelajaran yang bermakna. NEEDS ANALYSIS IN SOCIAL SCIENCE LEARNING AT PRIMARY SCHOOLThis study was aimed at exploring the obstacles and the needs in teaching social science at the primary school level. A descriptive approach method was used in this study. The data was obtained by observing the learning process, analyzing the teaching materials and media in learning, and analyzing the students’ test scores. The study was conducted for 5 months starting from April 2017 to August 2017. The collected data were examined by triangulation techniques to determine the relationship and comparability of the data. Data were then analyzed using the interactive-miles analysis according to Miles Huberman. The results show that the hand books were not interesting enough as there were too many theories but few pictures which would not encourage students to think critically; teachers tended to adopt a teacher-centered approach of teaching in which they dominated the class with their explanation and there were limited interactive sessions; the students tended to memorize more than master the theories; having limited teaching medias, the teachers made the learning process become abstract, while primary-school students needed to have activities which encouraged their way of thinking from concrete into abstract. An innovation which suits primary school students’ character is needed to create a meaningful learning process.

Tujuan dari penelitian ini untuk mengetahui pengaruh cekaman NaCl terhadap pertumbuhan dan anatomi akar tanaman bayam serta mengetahui konsentrasi NaCl yang dapat menghambat pertumbuhan tanaman bayam. Penelitian ini digunakan perlakuan NaCl sebanyak 0, 200, 400, 600 dan 800 mM pada tanaman bayam (Amaranthus tricolor L.), Media tanam berupa campuran tanah dan pupuk kandang dan alkohol, safranin, aseton. Alat yang digunakan adalah med line, cawan poerslen, spektrofotometer dan mikroskop. Parameter yang diukur meliputi tinggi tanaman, jumlah daun, warna daun, panjang akar, jumlah akar, berat basah, berat kering, kadar klorofil, tebal epidermis akar, tebal korteks akar dan diameter stele akar. Data dianalisis dengan uji ANOVA dilanjutkan dengan DMRT taraf kepercayaan 95% menggunakan program SPSS 15. Hasil yang diperoleh menunjukkan penambahan NaCl menyebabkan penurunan pertumbuhan tanaman bayam meliputi tinggi tanaman, jumlah daun, kadar klorofil, rasio tajuk dibanding akar dan menurunkan diameter stele akar. Pertumbuhan tanaman menurun seiring peningkatan konsentrasi NaCl karena NaCl menyebabkan cekaman osmotik yang menghambat penyerapan air dan unsur hara yang diperlukan tanaman untuk proses metabolisme.PHYSIOLOGICAL RESPONSE AND ANATOMY OF ROOTY PLANT [ Amaranthus tricolor L.] AGAINST NaClThe study was aimed at determining the effect of NaCl stress on the growth and anatomy of spinach roots and the concentration of NaCl which can inhibit the growth of spinach plants. This study used 0, 200, 400, 600 and 800 mM NaCl treatments on spinach (Amaranthus tricolor L.), planting media in the form of a mixture of soil and manure and alcohol, safranin, acetone. Med line, poerslen cup, spectrophotometer, and microscope were used in this study. The parameters measured plant height, number of leaves, leaf color, root length, number of roots, wet weight, dry weight, chlorophyll content, root epidermis thickness, root cortex thickness, and root stele diameter. The collected data then were analyzed by ANOVA test followed by DMRT 95% confidence level using the SPSS 15 program. The results obtained showed that the addition of NaCl caused a decrease in spinach plant growth including plant height, the number of leaves, chlorophyll content, the ratio of the crown to root and decreased diameter of root stele. Plant growth decreases with increasing NaCl concentration since NaCl causes osmotic stress. This stress inhibits the absorption of water and nutrients needed by plants for metabolic processes.

Public Perception of Artificial Intelligence in Medical Care: Content Analysis of Social Media
Authors: Gao Shuqing , He Lingnan , Chen Yue , Li Dan , Lai Kaisheng
Published: July 2020

Background

High-quality medical resources are in high demand worldwide, and the application of artificial intelligence (AI) in medical care may help alleviate the crisis related to this shortage. The development of the medical AI industry depends to a certain extent on whether industry experts have a comprehensive understanding of the public’s views on medical AI. Currently, the opinions of the general public on this matter remain unclear.

Objective

The purpose of this study is to explore the public perception of AI in medical care through a content analysis of social media data, including specific topics that the public is concerned about; public attitudes toward AI in medical care and the reasons for them; and public opinion on whether AI can replace human doctors.

Methods

Through an application programming interface, we collected a data set from the Sina Weibo platform comprising more than 16 million users throughout China by crawling all public posts from January to December 2017. Based on this data set, we identified 2315 posts related to AI in medical care and classified them through content analysis.

Results

Among the 2315 identified posts, we found three types of AI topics discussed on the platform: (1) technology and application (n=987, 42.63%), (2) industry development (n=706, 30.50%), and (3) impact on society (n=622, 26.87%). Out of 956 posts where public attitudes were expressed, 59.4% (n=568), 34.4% (n=329), and 6.2% (n=59) of the posts expressed positive, neutral, and negative attitudes, respectively. The immaturity of AI technology (27/59, 46%) and a distrust of related companies (n=15, 25%) were the two main reasons for the negative attitudes. Across 200 posts that mentioned public attitudes toward replacing human doctors with AI, 47.5% (n=95) and 32.5% (n=65) of the posts expressed that AI would completely or partially replace human doctors, respectively. In comparison, 20.0% (n=40) of the posts expressed that AI would not replace human doctors.

Conclusions

Our findings indicate that people are most concerned about AI technology and applications. Generally, the majority of people held positive attitudes and believed that AI doctors would completely or partially replace human ones. Compared with previous studies on medical doctors, the general public has a more positive attitude toward medical AI. Lack of trust in AI and the absence of the humanistic care factor are essential reasons why some people still have a negative attitude toward medical AI. We suggest that practitioners may need to pay more attention to promoting the credibility of technology companies and meeting patients’ emotional needs instead of focusing merely on technical issues.

Decision trees made by visualizing the decision-making process solve a problem that requires more successive decisions to be made. They are also used for classification and to solve problems usually addressed by regression analysis. One of the problems of classification that arises is the proper classification of bankrupt companies and non-bankruptcy companies, which  is then used to predict the likelihood of bankruptcy. The paper uses a random forests decision tree to predict bankruptcy of companies in the Republic of Serbia. The research results show the high predictive power of the model with as much as 98% average prediction accuracy, and it is recommended for auditors, investors, financial institutions and other stakeholders to predict bankruptcy of companies in Republic of Serbia.

Published: July 2020

A range of explanations had been offered for the apparent change in oil price-inflation relationship outcomes ranging from the possible use of alternate energy sources, change in the structure of output regarding fewer oil intensive sectors and the role of fiscal and monetary in the affected oil-exporting countries. These changes had drawn the attention of stakeholders, government and the society at large to the anecdotal relationship among oil price volatility, inflation, and output in Africa oil-exporting countries. This study leans empirical credence to the impact of oil price volatility on inflation and economic performance in the Africa oil-exporting countries from 1995 through 2017. We employed the Pool Mean Group estimation procedure with the inference drawn at a 5% level of significance. We found that oil price volatility had a negative and significant effect on inflation in Africa oil-exporting countries. The study concluded that oil price volatility had a substantial impact on inflation in the Africa oil-exporting countries. The study, therefore, recommended that Africa oil-exporting countries should adopt precautionary measures to monitor inflation potentials due to different responses of inflation to positive and negative oil price shocks.
