Published: August 2021

Study Design: Retrospective cohort study.Purpose: This study aimed to elucidate cases for which staged surgeries are effective by a retrospective review of previous operative cases of spinal ependymomas.Overview of Literature: Patients with spinal ependymomas are expected to have a good prognosis following total resection. However, forcible dissection of spinal ependymomas will lead to neurological deterioration. Moreover, resection is sometimes difficult when the tumor is large. We have performed two-stage surgeries for large spinal ependymomas, but the indication of staged surgery is unclear.Methods: We retrospectively reviewed patients diagnosed with spinal ependymomas who underwent tumor resection in our institution. We obtained data regarding patients’ clinical characteristics, tumoral radiological characteristics, and surgical factors and compared them to clear prognostic factors. Two-stage surgery was performed in 11 patients (36.7%), and single surgery was performed in 19 patients (63.3%).Results: Thirty patients were included in the analyses and divided into two groups: single surgery and two-stage surgery groups. In the single surgery group, high tumor–cord ratio (TCR) and intraoperative motor evoked potential (MEP) reduction were significantly correlated with unfavorable outcomes, which were defined as deterioration of the modified McCormick scale grades 2 months and 1 year postoperatively. Alternatively, these factors were not significantly correlated with postoperative unfavorable outcomes in the two-stage surgery group. Receiver operating characteristic curves indicated that TCR of 0.866 yielded 85.7% sensitivity and 83.3% specificity 2 months postoperatively.Conclusions: The results suggested that high TCR might be an indication of two-stage surgery and that its cutoff value is 0.866. Moreover, switching from single surgery to two-stage surgery may prevent postoperative neurological deterioration when intraoperative MEP is decreasing.

Sports has grown into a big industry these days. The professional approach to sports, its commer-cial value and spectator interests has brought about substantial changes in how a sport is played and viewed. These changes has brought about eye catching performances from the players and with more and more spectators enjoying sports, the need to judge the application of laws, rules and regulations governing such sports has also changed drastically. The pressure on umpires, referees and judges to be error free is like never before. Given such circumstances how a game is being evolved, how the spectator’s interest is being cultivated and how the impact of any decision is felt by a player concerned is becoming more critical than ever before. With this background a survey was initiated to gather the opinion of various stakeholders to arrive at some logical conclusion on how technology in influencing Law, Rules and Regulations of Sports and Games and if it needs to be so. A specific questionnaire was designed and circulated among interested participants not only locally but across the world. The responses supported the use of technology in sports today though some of the participants felt that technology may not be an answer as a foolproof method to overcome human error.

PURPOSE Critically ill elderly patients who suffer from Sars-CoV-2 disease are at high risk for organ failure. The modified MELD-XI score has not been evaluated for outcome prediction in these most vulnerable patients. METHODS The Corona Virus disease (COVID19) in Very Elderly Intensive Care Patients study (COVIP, NCT04321265) prospectively recruited patients on intensive care units (ICU), who were = 70 years. Data were collected from March 2020 to February 2021. The MELD-XI score was calculated using the highest serum bilirubin and creatinine on ICU admission. Univariate and multivariable logistic regression analyses were performed to assess associations between the MELD-XI score and mortality. The primary outcome was 30-day-mortality, the secondary outcomes were ICU- and 3-month-mortality. RESULTS In total, data from 2,993 patients were analyzed. Most patients had a MELD-XI <12 on admission (76%). The patients with MELD-XI = 12 had a significantly higher 30-day-, ICU- and 3-month-mortality (44%vs 64%, and 42%vs. 59%, and 57%vs. 76%, p < 0.001). After adjustment for multiple confounders, MELD-XI = 12 remained significantly associated with 30-day- (aOR 1.572, CI 1.268–1.949, p < 0.001), ICU-, and 3-month-mortality. CONCLUSION In critically ill elderly intensive care patients with COVID-19, the MELD-XI score constitutes a valuable tool for an early outcome prediction.
Next generation Open Access analytics: A case study
Authors: Lloyd Tim , Rouhi Sara
Published: August 2021

A critical component in the development of sustainable funding models for Open Access (OA) is the ability to communicate impact in ways that are meaningful to a diverse range of internal and external stakeholders, including institutional partners, funders, and authors. While traditional paywall publishers can take advantage of industry standard COUNTER reports to communicate usage to subscribing libraries, no similar standard exists for OA content. Instead, many organizations are stuck with proxy metrics like sessions and page views that struggle to discriminate between robotic access and genuine engagement. This paper presents the results of an innovative project that builds on existing COUNTER metrics to develop more flexible reporting. Reporting goals include surfacing third party engagement with OA content, the use of graphical report formats to improve accessibility, the ability to assemble custom data dashboards, and configurations that support the variant needs of diverse stakeholders. We’ll be sharing our understanding of who the stakeholders are, their differing needs for analytics, feedback on the reports shared, lessons learned, and areas for future research in this evolving area.
Agent-based access control framework for enterprise content management
Authors: Hocine Nadia
Published: August 2021

Telework is an important alternative to work that seeks to enhance employees’ safety and well-being while reducing the company costs. Employees can work anytime, any where and under high mobility conditions using new devices. Therefore, the access control of remote exchanges of Enterprise Content Management systems (ECM) have to take into consideration the diversity of users’ devices and context conditions in a telework open network. Different access control models were proposed in the literature to deal with the dynamic nature of users’ context and devices. However, most access control models rely on a centralized management of permissions by an authorization entity which can reduce its performance with the increase of number of users and requests in an open network. Moreover, they often depend on the administrator’s intervention to add new devices’ authorization and to set permissions on resources. In this paper, we suggest a distributed management of access control for telework open networks that focuses on an agent-based access control framework. The framework uses a multi-level rule engine to dynamically generate policies. We conducted a usability test and an experiment to evaluate the security performance of the proposed framework. The result of the experiment shows that the ability to resist deny of service attacks over time increased in the proposed distributed access control management compared with the centralized approach.

Published: August 2021

Different high performance techniques, such as profiling, tracing, and instrumentation, have been used to tune and enhance the performance of parallel applications. However, these techniques do not show how to explore the potential of parallelism in a given application. Animating and visualizing the execution process of a sequential algorithm provide a thorough understanding of its usage and functionality. In this work, an interactive web-based educational animation tool was developed to assist users in analyzing sequential algorithms to detect parallel regions regardless of the used parallel programming model. The tool simplifies algorithms’ learning, and helps students to analyze programs efficiently. Our statistical t-test study on a sample of students showed a significant improvement in their perception of the mechanism and parallelism of applications and an increase in their willingness to learn algorithms and parallel programming.
Monitoring the newly infected cases of COVID-19 data weekly: A Survival Data Analysis (SDA) perspective
Authors: Ramasamy Ramachandran , Kaliannan Maniam
Published: August 2021

This paper attempts to fit the best survival model distribution for the Malaysian COVID-19 new infections experience of Wave I/II and Wave III using the well-known Survival Data Analysis (SDA) procedures. The purpose of fitting such models is to reduce the complexity and frequency of the COVID-19 new infections data into a single measure of scale and shape parameters to enable monitoring of weekly trends, undertake short term forecasts and estimate duration when the virality will be contained. The analysis showed a Weibull distribution is the best statistical fit for Malaysia’s new infections COVID-19 data. The estimates of scale and shape parameters for Wave I/II was 0.05901 and 2.48956 and for Wave III was 0.06463 and 2.5693, respectively. Much higher hazard force in Wave III is due to weaker control in the implementation of cordon sanitaire measures imposed in containing the virality spread. Based on the survival function the short-term forecasts showed that the number of new infections projected to decline from 23,282 cases in 28th week to 22,017 cases in 31st week. Similarly, based on the cumulative hazard function the duration estimated for containing the virality completely projected to stretch over another 19.6 weeks under the prevailing conditions.
Kinematics study of a 10 degrees-of-freedom lower extremity exoskeleton for crutch-less walking rehabilitation
Authors: Liu Jingshuai , He Yong , Li Feng , Cao Wujing , Wu Xinyu
Published: August 2021

BACKGROUND: Wearable lower extremity exoskeletons can provide walking assistance for the physical rehabilitation of paralyzed individuals. However, most of the existing exoskeletons require crutches to maintain balance, thus a self-balancing type is needed to improve applicability. OBJECTIVE: The purpose of this work is to study the kinematic characteristics of a novel lower extremity exoskeleton for crutch-less walking rehabilitation, and evaluate the movement performance through practical experiments. METHODS: Based on the human lower limb structure and movement characteristics, a fully actuated 10 degrees-of-freedom (DoF) lower extremity exoskeleton was proposed. The kinematic characteristics of the exoskeleton were analyzed by the D-H method and geometric method, and the model validity was verified through simulations and experiments. RESULTS: The closed-form solutions for both forward and inverse kinematics models were obtained. The consistent results of theoretical calculation and numerical simulation have shown the accuracy of the established models. The practical experiments regarding six trials have demonstrated the movement performance of the proposed exoskeleton, including sit, stance, leg extension/flexion, and left/right swing. CONCLUSIONS: The kinematic characteristics of the proposed 10-DoF lower extremity exoskeleton are similar to the human lower limb, and it could meet the motion demands of crutch-less walking rehabilitation.
The myeloid cell biomarker EMR1 is ectopically expressed in colon cancer
Authors: Ali Haytham , Olsson Lina , Lindmark Gudrun , Hammarström Marie-Louise , Hammarström Sten , Sitohy Basel
Published: August 2021

OBJECTIVE:

The microenvironment of colon cancer (CC) is heterogeneous including cells of myeloid lineage affecting tumor growth and metastasis. Two functional subtypes of myeloid cells have been identified; one (M1) is tumor-inhibitory and the other one (M2) is tumor-promoting. Whether the three myeloid markers EMR1, CD206 and CD86 are expressed only in the infiltrating myeloid cells or also in the tumor cells was investigated.

METHODS:

Expression of the myeloid markers was investigated in CC at the mRNA and protein levels in primary tumors and lymph nodes. mRNA expression was also determined in 5 CC cell lines. Protein expression was investigated by two-color immunofluorescence and consecutive-sections-immune-staining combined with morphometry using specific antibodies for the myeloid cell markers and the epithelial cell markers CEACAM5 and EpCAM.

RESULTS:

EMR1 and CD86, but not CD206, mRNA levels were significantly higher in CC primary tumors compared to apparently normal colon tissue ( P <  0.0001). EMR1 mRNA levels were significantly higher in both hematoxylin-eosin positive (H&E(+)) and H&E(–) lymph nodes of CC patients compared to control nodes ( P = 0.03 and P = 0.01, respectively). EMR1 and CD206 mRNAs were expressed in 4/5 and 5/5 CC cell lines, respectively, while CD86 mRNA was not expressed. Immuno-morphometry revealed that about 20% of the tumor cells expressed EMR1 and CD206. Positive cells were tumor cells as revealed by anti-CEACAM5 and anti-EpCAM staining. The number of EMR1, CD206 and CD86 positive cells were significantly increased in CC primary tumors compared to normal colon tissue ( P <  0.0001). However, CD206 was also expressed in normal colonocytes. Only EMR1 showed significantly increased numbers of positive tumor cells in H&E(+) nodes compared to H&E(-) nodes ( P = 0.001). EMR1 expression in CC tumor cells correlated with CXCL17 expressing tumor cells.

CONCLUSION:

EMR1, like the chemokine CXCL17, is ectopically expressed in colon cancer possibly in the same cancer cells.

Published: August 2021

Precise segmentation of lung parenchyma is essential for effective analysis of the lung. Due to the obvious contrast and large regional area compared to other tissues in the chest, lung tissue is less difficult to segment. Special attention to details of lung segmentation is also needed. To improve the quality and speed of segmentation of lung parenchyma based on computed tomography (CT) or computed tomography angiography (CTA) images, the 4th International Symposium on Image Computing and Digital Medicine (ISICDM 2020) provides interesting and valuable research ideas and approaches. For the work of lung parenchyma segmentation, 9 of the 12 participating teams used the U-Net network or its modified forms, and others used the methods to improve the segmentation accuracy include attention mechanism, multi-scale feature information fusion. Among them, U-Net achieves the best results including that the final dice coefficient of CT segmentation is 0.991 and the final dice coefficient of CTA segmentation is 0.984. In addition, attention U-Net and nnU-Net network also performs well. In this paper, the methods chosen by 12 teams from different research groups are evaluated and their segmentation results are analyzed for the study and references to those involved.

Lepidoptera associated with Boerhavia diffusa L. (Nyctaginaceae) in lower Ivory Coast. Two eggs, seventy two caterpillars and six pupae collected mainly in Abidjan on Boerhavia diffusa L., a ruderal Nyctaginaceae, and reared, allowed to show that this plant favors the subsistance of at least seven species of Lepidoptera in an extremely urbanized environment: Megalorhipida leucodactyla (Fabricius, 1794) (Pterophoridae), Hippotion celerio (Linnaeus, 1758) (Sphingidae), Disclisioprocta natalata (Walker, 1862) (Geometridae), Alpenus maculosa Boisduval, 1836 (Erebidae), Maliattha sp., Spodoptera littoralis (Boisduval, 1833) and Aegocera rectilinea Boisduval, 1836 (Noctuidae). Disclisioprocta natalata is cited for the first time from Ivory Coast.
Saját törvényeik szerint? : A középiskolai tanárok szakmai autonómiája a 19. század végén
Authors: Keller Márkus
Published: August 2021

A tanulmányban a magyarországi középiskolai tanárok szakmai autonómiájának alakulását vizsgálom a 19. század második felében. Ez az időszak különösen fontos a középiskolai tanárság életében, hiszen a magyarországi polgári társadalom kialakulásával egy időben sejlik fel előttük a hivatássá válás lehetősége. A középiskolai tanárok egyesületének vizsgálata megmutatta, hogy az autonómia kialakítása és megtartása fontos célja volt a korabeli tanárságnak, és készek voltak ennek érdekében ütközni az állammal és az iskolák többségét fenntartó egyházakkal egyaránt. Írásomban amellett érvelek, hogy az egyre erősödő állami ellenőrzés és szabályozás, illetve a Magyarországon különösen fontos egyházi fenntartók befolyása ellenére a középiskolai tanárok és tanári karok számottevő szakmai autonómiával rendelkeztek.

Aralık 2019'da, Çin'de Yeni Koronavirüs (SARS-CoV-2) olarak bilinen bir koronavirüs tespit edilmiş ve dünya çapında bir salgın haline gelmiştir. COVID-19’dan korunmanın temel yolu, izolasyon ve sosyal uzaklaşma stratejileri olmuştur. Bu çalışmada, COVID-19 nedeni ile izole edilen ebeveynlerin çocuklarını depresyon, anksiyete ve travma sonrası stres bozukluğu (TSSB) belirtileri açısından değerlendirdik. Çalışmaya anne ve/veya babası son 3 ay içinde COVID-19 enfeksiyonu geçirmiş 52 çocuk dahil edilmiştir. Çocukların yaşları 7 yaş ile 17 yaş arasındadır ve 27’si kızdır. Tüm çocuklara, Çocuklar için Depresyon Ölçeği, Çocuklar için Travma Sonrası Stres Tepki Ölçeği, Çocukluk Anksiyete Tarama Ölçeği, Psikolojik Sağlamlık Ölçeği uygulanmıştır. Çocukların %19.2’sinde depresif semptomların olduğu, depresyon semptomların kronik hastalığı olanlarda %40, tanı almış psikiyatrik hastalığı olanlarda %50 olduğu tespit edilmiştir. Çocuklarda, değişen düzeylerde TSSB belirtileri saptanmıştır. Annesi izole edilenlerde, ağır TSSB belirtileri oranı %35.1; babası izole edilenlerde %6.7’dir. Her iki ebeveyni de COVID-19 enfeksiyonu geçiren çocuklarda anksiyete puanı en yüksek bulunurken, bunu sırasıyla sadece annesi geçiren çocuklar ve sadece babası geçirenler izlemiştir. Bilim adamlarının koronavirüsü iyi anladıkları, ülkemizde Sağlık Bakanlığı’nın süreci iyi yönettiği, koronavirüsün yayılmasını kısıtlamak için kendi alacağı ve ülkemizde alınacak koruyucu önlemlerin fark oluşturacağı fikrine katılmayan çocuklarda depresyon semptom sıklığı daha yüksek bulunmuştur. Ayrıca, bilim adamlarının koronavirüsü iyi anladıkları fikrine katılmayan ve ülkemizde uygulanan kuralların günlük yaşamlarına çok fazla müdahalede bulunduğunu düşünen çocuklarda, ağır TSSB belirti sıklığının daha yüksek olduğu gösterilmiştir. COVID-19 salgını ile günlük yaşamları kısıtlanmış olan çocukların; bilişsel, duygusal, fiziksel ve psikolojik gelişimlerinin henüz tamamlanmamış olduğu dikkate alındığında, bu süreçte yaşayabilecekleri sorunlara karşı uyumlarını arttırmak, psikolojik dayanıklılıklarını güçlendirmek için ruhsal destek sunulmalı ve etkin stratejiler izlenmelidir.

Whereas before there has been a North Atlantic Treaty Organization as a security pillar that has long been recognized in the European region. The author uses the theory of regional security complex and the concept of collective security in analyzing related phenomena. This research uses descriptive method with qualitative approach. The data collection technique is literature study consisting of books, journals, and including data from reliable websites to support the explanation of this paper. The results of this research indicate the establishment of PESCO as a form of implementation of Article 42 paragraph 6 of the Lisbon Treaty in 2009 concerning the efforts of member countries in establishing defense-security cooperation within the European Union framework. The establishment of the PESCO was also based on doubts by the European Union on the role of the US in NATO, but PESCO did not directly replace NATO but rather as a complement to autonomous and effective crisis resolution.

However, in its development, South Sumatra's rubber commodity faces various obstacles to compete in international trade. The purpose of this study was to examine how the competitiveness of South Sumatra's natural rubber commodities in international trade. The concept of competitiveness and the theory of competitive advantage is used to describe the research results. The method used in this study is descriptive explanatory, data collection was obtained by interviewing the South Sumatra Province Plantation Service and GAPKINDO of South Sumatra, as well as through the results of a literature study. The findings of this study are seen through 4 determinants of competitive advantage, factor conditions, demand condition, related and supporting Industries, then firm strategy, structure, and rivalry. As well as additional factors,  governance. Production of rubber plantations in South Sumatra has decreased. Rubber demand also declined based on data on the volume of rubber exports. South Sumatra's downstream industry has not yet developed. Then the strategy applied is less than optimal and the role of the Government of South Sumatra is lacking. So it can be concluded that the competitiveness of South Sumatran rubber commodities in international trade is low.
