A Neural Network Aided Real-Time Hospital Recommendation System
Authors: Paranjay Om Adideva , Rajeshkumar V 
Published: March 2021

Over the past few years, there have been an overwhelming number of healthcare providers, hospitals and clinics. In such a situation, finding the right hospital for the right ailment can be a considerable challenge. Inspired by this challenge, this work attempts to build a model that can automatically recommend hospitals based on user requirements. In the past there have been important works in physician recommendation. Our proposed work aims to be more inclusive and provide an automated hospital recommendation system to patients based on neural networks driven classification. We suggest a model that considers several unique parameters, including geographical location. To optimize its usefulness, we design a system that recommends hospitals for general consultation, specialty hospitals, and in view of the pandemic, hospitals recommended for treatment of COVID-19. In this work, we adopt Neural Networks and undertake a comparative analysis between several different available supervised algorithms to identify one best suited neural architecture that can work best in the applied fields. Based on our results from the analysis, we train the selected neural network with context relevant data. In the image of the recommendation system, we develop a website that uses the trained neural network on its backend and displays the recommendation results in a manner interpretable by the end user. We highlight the process of choosing the right neural model for the backend of the website. To facilitate the working of the website in real-time, we use real time databases hosted on Google Firebase and edge devices on hospital ends. Additionally, we suggest two hospital side data updation tools. These tools would ensure that hospitals can update the parameters which change quickly in the real world to their latest values so as to maintain the precision of the system. We test the website with test data and find that the website recommends hospitals with sufficient precision in the specified format. The model has been designed with the limited amount of data available in this field, but its performance and utility can be easily improved with better quality and more abundant data.

Published: March 2021

Abstract
Cobalt ferrite (CoFe2O4) nanoparticles were synthesized through three different routes (chemical co-precipitation, ceramic, and sol-gel). The products were characterized by XRD, SEM, TEM, Raman spectroscopy, FTIR, photoluminescence (PL), BET, XPS, vibrating sample magnetometer (VSM). The X-ray analysis validates the spinel structure of the samples with particle sizes between 21 – 36 nm. XPS revealed the impact of the preparation route on cation distribution at the tetrahedral and octahedral sites in spinel ferrite lattice. All ferrite surfaces exhibit a mesoporous structure with a surface area between 25 – 99 m2/g. The results show that the prepared samples exhibit either ferromagnetic or super-paramagnetic behavior. The ferrite samples showed a photocatalytic performance under visible light. The present work demonstrates that each of the particle size and cation distribution is effective in controlling the structural, magnetic, and optical properties. The results obtained reveal that this kind of CoFe2O4 spinel ferrite nanoparticles has promising applications in magnetic designs and water treatment fields.

Abstract
BackgroundTight junction (TJ) imbalance is associated with hepatocellular carcinoma (HCC). MarvelD3, which contains a conserved MARVEL (MAL and related proteins for vesicle trafficking and membrane link) domain similarly to occludin and tricellulin, is a recently identified integral membrane protein that forms TJs. However, little is known about the possible roles of marvelD3 in epithelial–mesenchymal transition (EMT) and metastasis of HCC. We aimed to demonstrate the role of marvelD3 in inhibiting HCC EMT and migration and further explore the underlying molecular mechanisms.MethodsMarvlD3 expression was assessed in HCC and normal liver tissues. Changes in marvelD3 expression were analyzed during transforming growth factor β1 (TGF-β1) and snail/slug-induced EMT. MarvelD3 knockdown HCC cell lines were established using marvelD3-siRNA to analyze correlations between marvelD3 and EMT-related proteins. Tumor cell behaviors were analyzed in marvelD3 knockdown HCC cells. Associations between marvelD3 and genes in the nuclear factor (NF)-κB pathway were also analyzed.ResultsLoss of marvelD3 expression was significantly correlated with the occurrence and TNM stage of HCC. MarvelD3 was downregulated in HCC cells with TGF-β and snail/slug-induced EMT. Expression of marvelD3 protein was significantly associated with E-cadherin and vimentin in HCC cell lines. Knockdown of marvelD3 promoted tumor cell migration concomitant with activation of the NF-κB signaling pathway and increased matrix metallopeptidase 9 expression.ConclusionsOur study demonstrated that MarvelD3 inhibited EMT and migration of HCC cells via NF-κB signaling pathway. This suggests that marvelD3 is a novel potential biomarker for the treatment and prognosis of HCC.

Abstract
The present study is directed to the temperature and residual stresses fields in the hardfacing remanufacturing for a large-scale grinding roller with damage. For this purpose, a numerical procedure for the hardfacing process based on thermal cycle curve method was established, and the effectiveness of the proposed procedure was verified by the measurements of a multi-pass welding experiment with V-groove butt joint. Considering the characteristics of the hardfacing process, a local model of bead-on-plate welding was used to check the heat source and extract the thermal cycle curve. The resulting thermal cycle curve was applied as a thermal load to the corresponding welding layer one by one. Based on the calculated material properties, the data files of the base metal (Grade:KmTBCr26) and the filling layers (Grade:ARCFCW9024) were re-developed to define the temperature-dependent physical and mechanical properties of the materials used in the hardfacing remanufacturing. The numerical simulation results reveal the changing trend and distribution of the temperature and residual stress fields during the hardfacing remanufacturing for the damaged grinding roller. The distribution of temperature and residual stress is very complicated due to the numerous welding layers in the hardfacing process. It is pointed out that with the increase of surfacing layers, the heat-affected zone of the grinding roller expands gradually, and the maximum tensile stress always appears at the position near the weld toe, which is prone to fatigue failure or interface peeling due to stress concentration.

Abstract
Microplastics (MPs) have been detected in drinking water and raw water sources. Therefore, it is important to know the performance of drinking water treatment process. The rapid sand filter (RSF) is one of the water treatments that can be an alternative treatment in removing MPs after several configuration processes (pre-sedimentation, coagulation-flocculation, and sedimentation). This study aims to determine the effectiveness of RSF to remove MPs. The artificial samples were made from plastics bags and tyre flakes, with sizes from 10 μm to more than 500 μm. Bentonite was added to represent turbidity in the water. The average removal efficiency of plastics flakes before entering the filter was 50.48% (using bentonite) and 47.78% (without bentonite). Overall, the removal efficiency for the tyre flakes was 90.72% (using bentonite) and 93.03% (without bentonite). The filtration used in this study was varied between 4 and 10 m/h. Removal efficiency using RSF for plastic flakes on which the Effective Size (ES) filter media 0.39 mm was 97.7% and on which ES 0.68 mm was 94.3%. Meanwhile, the removal efficiency of the tyre flakes for ES 0.39 mm were 90.6% and ES 0.68 mm was 85.2%. However, in this study, RSF mostly removed MPs particles greater than 200 μm in size.

We focused on the extent to which the Military physical fitness and the physical self-concept will be affected by a basic military training program. Military physical fitness included the score of BMI, pull-ups, 3000m endurance running and 1-min sit-up. Physical self-concept was assessed using the Marsh's Physical Self-Description Questionnaire (PSDQ), which was adapted to use in college students. PSDQ scale was assessed using a 6-point rating scale on which the subject estimated their physical characteristics. Testing was administered in a pre- and posttest fashion over 9 weeks (n=166). The collected data were analyzed by t-test. The study revealed that 1) Military physical fitness that including 3000m endurance running, 1-min sit-up and BMI are significant (p<.05), (2) total score of PSDQ assessment are non-significant (p>.05), (3) the health of PSDQ are significant (p<.05), (4) the physical activity of PSDQ are significant (p<.05). Results show that physical fitness and psychological measurement are really affected by basic military training program such that cadets have a more positive health and better body conditions due to basic military training.
本研究的主要目的在於研究軍校新生在經過入伍訓練後其生理與心理方面的變化。我們研究主要焦點在於入伍訓練課程能否影響軍方體適能和身體自我概念，而軍中體適能的項目包含：拉單槓、3000公尺耐力跑、一分鐘仰臥起坐，身體自我概念的評估則是將Marsh的身體自我描述問卷(PSDQ)改編成適合大專學生適用的量表。PSDQ的評估使用六點等級讓受試者來評估自己的身體特點。測試分別在9周入伍訓練的前後實施(共166人)。收集到的資料以成對樣本T考驗檢定。本研究的結果呈現(1)軍方體適能中的3000公尺耐力跑，一分鐘仰臥起坐和BMI皆有顯著的變化(p<.05) (2) PSDQ的總得分並未變化(p>.05) (3) PSDQ的健康分項得分有顯著差異(p<.05) (4) PSDQ的身體活動分項得分有顯著差異(p<.05)。結果顯示體適能和心理方面的測量確實受到入伍訓練的影響，所以軍校生會因為入伍訓練而有更積極正向的健康概念與較佳的身體狀況。

BackgroundHair follicle tissue engineering is a promising strategy for treating hair loss. Human hair follicle stem cells (hHFSCs), which play a key role in the hair cycle, have potential applications in regenerative medicine. However, previous studies did not achieve efficient hHFSC expansion in vitro using feeder cells. Therefore, there is a need to develop an efficient primary culture system for the expansion and maintenance of hHFSCs.MethodsThe hHFSCs were obtained by two-step proteolytic digestion combined with microscopy. The cell culture dishes were coated with human fibronectin and inoculated with hHFSCs. The hHFSCs were harvested using a differential enrichment procedure. The effect of Rho-associated protein kinase (ROCK) inhibitor Y-27632, supplemented in keratinocyte serum-free medium (K-SFM), on adhesion, proliferation, and stemness of hHFSCs and the underlying molecular mechanisms were evaluated.ResultsThe hHFSCs cultured in K-SFM, supplemented with Y-27632, exhibited enhanced adhesion and proliferation. Additionally, Y-27632 treatment maintained the stemness of hHFSCs and promoted the ability of hHFSCs to regenerate hair follicles in vivo. However, Y-27632-induced proliferation and stemness in hHFSCs were conditional and reversible. Furthermore, Y-27632 maintained propagation and stemness of hHFSCs through the ERK/MAPK pathway.ConclusionAn efficient short-term culture system for primary hHFSCs was successfully established using human fibronectin and the ROCK inhibitor Y-27632, which promoted the proliferation, maintained the stemness of hHFSCs and promoted the ability to regenerate hair follicles in vivo. The xenofree culturing method used in this study provided a large number of high-quality seed cells, which have applications in hair follicle tissue engineering and stem cell therapy.

Published: March 2021

ABSTRACT

Introduction
The objective of this study was to assess the effectiveness of the Saudi national accreditation program on patient safety culture in a secondary-tertiary public hospital in Saudi Arabia.

Methods
Three hundred health professionals were randomly selected to participate in a survey. The survey was used in three phases: baseline, before accreditation, and after accreditation. Primary and secondary outcome measures were teamwork within hospital units, feedback and communication about errors, hospital handoffs and transitions, overall perceptions of safety, frequency of event reporting, and perception of patient safety grade.

Results
The survey response rate was 100%. A statistically significant impact of accreditation was found for teamwork within hospital units, feedback and communication about errors, and hospital handoffs and transitions (p = 0.002, 0.009, and 0.010, respectively). Ordinal logistic regression confirmed that the accreditation program had a significant effect on overall perceptions of safety (odds ratio [OR] [1.42–13.56], p = 0.010), frequency of event reporting (OR [0.91–7.96], p = 0.073), and staff awareness of grading safety culture (OR [0.02–0.70]) and reporting behavior (OR 0.10 [0.03–0.37]).

Conclusion
The Saudi national accreditation program had a significant positive impact on some patient safety culture dimensions and outcomes. These findings provide local empirical evidence on the benefits of implementing national accreditation programs. Further research on a larger scale is highly recommended.

Published: March 2021

This research work has aimed at investigating the level of political awareness among the Al Ain University students and the role of the university in boosting it by using the descriptive survey method. Indeed, this study has relied upon the questionnaire and the interview as research tools, as well as on the intentional sample where 10 teaching team members were interviewed to answer the third question, and on the random sample where the questionnaire was distributed among 980 students- males and females to answer the first and second questions. The findings of this study revealed that there was a considerably high level of political awareness among the university students. It was also found that there were differences in the level of political awareness among students depending on the faculty, which favoured the students belonging to faculties of humanities. The differences also favoured male students when the variable was gender and 4th year students when the variable was the year of study. In addition, the study showed that the university played 15 important roles in developing political awareness as was unanimously agreed by the members of the sample. These roles were identified by using recurrences and percentages ranging between 50 and 90%, while those with percentages lower than 50% were not taken into account.

La métropole, une affaire d’élus. La mise à distance des citoyens dans la réforme territoriale (2012-2016)
Authors: Parnet Christophe 
Published: March 2021

Cet article est consacré à la création des métropoles en France à travers la loi MAPTAM, conçue comme l’un des trois volets de l’« Acte III de la décentralisation », lequel poursuit un objectif de renforcement de la participation citoyenne. Or, cet objectif constitue en réalité la variable d’ajustement d’une réforme qui se caractérise au contraire par la mise à distance des citoyens. Captée par les élus locaux les plus dotés en ressources politiques, elle est contestée par d’autres élus, bien moins dotés. Ces derniers vont d’abord chercher à impliquer les citoyens pour contrer cette asymétrie de ressources, avant que cette contestation ne soit finalement réglée par des négociations discrètes entre élus.

Published: March 2021

Background:
Internet dependency has become one of the 21st century dilemmas affecting different aspects of married life such as sexual relationships. Considering the importance of family in the Iranian society, this study aimed to determine how internet dependency is related to sexual desires and satisfaction among married clients of healthcare centers.

Materials and Methods:
This cross-sectional study was conducted on 326 married clients referred to healthcare centers in Tabriz City, Iran, between February and August 2019. Proportionate stratified random sampling was used based on the health complexes and the healthcare centers covered by them. One of the healthcare centers covered by each complex was selected randomly. The data collection tools included a demographic characteristics checklist, the Internet Addiction Test (IAT), the Index of Sexual Satisfaction (ISS), and the Hurlbert Index of Sexual Desire (HISD). The collected data were analyzed using the Pearson correlation coefficient test and multiple linear regression model.

Results:
The mean (SD) was 37.33 (15.37) for of internet dependency, 59.20 (17.27) for sexual desire, and 104.45 (22.81) for sexual satisfaction. There was a negative correlation between internet dependency and sexual satisfaction (r = -0.47, p < 0.001). This correlation remained significant (B = -0.41, df = 9, p < 0.001,) even when occupation (B = 3.66, p = 0.01), satisfaction with married life (B = 15.34, p < 0.001), and sexual desire (B = 0.60, p < 0.001) were adjusted as potential confounding factors.

Conclusions:
Internet dependency can cause a reduction in sexual desire and sexual satisfaction. Designing educational interventions in healthcare centers is recommended to manage the use of internet and to inform clients about the effects that internet dependency may have.
