Published: November 2020

Background: Tumor positivity and upstaging rates from various surgical
staging components performed in clinically early-stage epithelial
ovarian carcinoma (EOC) vary widely in literature. Objectives: To
quantify tumor positivity and upstaging rates for all staging surgery
components in EOC patients. Differences between subgroups based on their
clinical and histological characteristics are explored. Search strategy:
A systematic search using synonyms of ‘ovarian cancer’, ‘neoplasm
staging’, and ’neoplasm metastasis’ was conducted in PubMed, Embase, and
the Cochrane Library. Selection criteria: Meta-analysis was performed on
23 included studies, comprising 5194 clinical stage I or II EOC patients
who underwent comprehensive surgical staging. Data Collection and
Analysis: Studies were assessed using the Newcastle-Ottawa Scale
risk-of-bias tool. Pooled proportions and 95% confidence intervals were
calculated using an inverse variance weighted random-effects model. Main
Results: Overall upstaging rate of clinically early-stage EOC patients
was 18.7% (95%CI: 14.1-23.4%). Serous histology or high grade EOC
showed the highest upstaging rate at 35.3% (95%CI: 21.8-48.7%) and
40.9% (95%CI: 35.6-46.2%). Lymph node involvement resulted in an
upstaging rate of 8.7% (95%CI: 6.2-11.3%). Tumor was identified in
uterus, cytology, peritoneal biopsies, omentum and appendix in 6.2%
(95%CI: 1.8-10.7%), 18.4% (95%CI: 13.8-22.9%), 9.7% (95%CI:
3.8-15.6%), 5.2% (95%CI: 1.7-8.8%) and 3.6% (95%CI: 0.0-7.5%) of
EOC patients. The corresponding upstaging rates were 5.9% (95%CI:
1.4-10.4%), 8.5% (95%CI: 1.8-15.2%), 3.5% (95%CI: 1.0-6.0%),
3.9% (95%CI: 1.4-6.3%) and 1.6% (95%CI: 0.0-3.4%), respectively.
Conclusion: The attributive value of comprehensive surgical staging in
clinically early-stage EOC patients remains substantial, particularly in
serous and high grade tumors.
DroidClone: Attack of the android malware clones - a step towards stopping them
Authors: Alam Shahid , Sogukpinar Ibrahim
Published: November 2020

Code clones are frequent in use because they can be created fast with little effort and expense. Especially for malware writers, it is easier to create a clone of the original than writing a new malware. According to the recent Symantec threat reports, Android continues to be the most targeted mobile platform, and the number of new mobile malware clones grew by 54%. There is a need to develop techniques and tools to stop this attack of Android malware clones. To stop this attack, we propose DroidClone that exposes code clones (segments of code that are similar) in Android applications to help detect malware. DroidClone is the first such effort uses specific control flow patterns for reducing the effect of obfuscations and detect clones that are syntactically different but semantically similar up to a threshold. DroidClone is independent of the programming language of the code clones. When evaluated with real malware and benign Android applications, DroidClone obtained a detection rate of 94.2% and false positive rate of 5.6%. DroidClone, when tested against various obfuscations, was able to successfully provide resistance against all the trivial (Renaming methods, parameters, and nop insertion, etc) and some non-trivial (Call graph manipulation and function indirection, etc.) obfuscations.

Introduction/Objective. Revascularization in multivessel coronary artery disease (MVD) in patients with ST elevation myocardial infarction (STEMI) is a matter of debate. We sought to compare outcomes between revascularization strategies based on angiographic lesion severity or inducible ischemia. Methods. In prospective study, first ever STEMI patients with MVD, defined as > 70% stenosis in non-culprit vessel, treated with culprit only primary PCI were randomized to: A. Complete revascularization of all nonculprit significant lesions during initial hospitalization; B. Complete revascularization after 30 days, or C. Revascularization based on non-invasive testing for inducible ischemia. The study explored occurrence of major adverse cardio-cerebral events (MACCE) (cardiac death, repeated MI, cerebrovascular event). Results. The study enrolled 120 patients with door to balloon time within appropriate limits (A 51 ? 26 vs. B 47 ? 33 vs. C 44 ? 29 min, p = 0.604) The patients in group A underwent complete revascularization at 6 [4?7] days after primary PCI, while in the group B it was 35 [32?39] days. In group C, 16/43 (37.2%) patients underwent PCI at 82 [66?147] days after infarction (p < 0.001). The patients were followed for 2.7 ? 0.8 years. The events occurred less frequently in patients that underwent planned complete revascularization compared to those who underwent ischemia testing (7.8 vs. 20.9%, p = 0.040). Kaplan?Meier analysis favored complete delayed revascularization (MACCE A 8.8 vs. B 6.9 vs. C 20.9%, log rank p = 0.041). Conclusions. Planned, angiography guided, complete revascularization after initial event may be favorable strategy compared to single stress test for MVD in STEMI.

The understanding of Indonesian high school level teachers in Bengkulu City on writing scientific articles on research results is still low. This is evidenced by the small number of Indonesian language teacher publications in accredited national journals and it has an impact on teachers having difficulty advancing in rank. For this reason, the aim of this community service is to provide understanding to Indonesian high school teachers in Bengkulu City in writing scientific articles and how to publish them in accredited national journals through webinars and mentoring activities. The community service method uses webinars and online mentoring through the Zoom Cloud Meeting. Participants totaled 37 Indonesian high school teachers in Bengkulu City. Community service techniques use lecture, discussion, and practice techniques. Data collection techniques using questionnaires, documentation, and observation. The results of the webinar indicate that the Indonesian language teacher is able to write articles quite well, starting from writing titles, abstracts, introductions, methods, research results, discussions, conclusions and suggestions, and bibliography. However, some teachers still have difficulty in pouring out the introductory section, especially mapping research positions based on relevant research results, difficulty in pouring out the discussion, especially finding the novelty of their research results, and difficulty finding references from online journals. Then, from the results of mentoring, Indonesian language teachers still have difficulty in submitting and the process of fixing articles in the OJS system. Keywords: webinars; accompaniment; scientific journal articles; accredited national journal

Learning media is an intermediary used for student learning tools. Students inthe learning process feel bored with the delivery of material. Submission ofmaterial that is less varied causes students to be less active so that theunderstanding of the material is not optimal. The teacher uses torso media inlearning but the learning outcomes are still less than KKM (Minimumcompleteness criteria). One way to overcome this is by developing monopolygames as biology learning media. Monopoly game is a type of board gamethat aims to accumulate wealth and control complexes on a monopoly boardgame. The teacher can modify the shape of this monopoly board game (astuti:2014). The use of instructional media appropriately and varied can overcomethe passive attitudes of students and overcome boredom during the learningprocess.

The Jews in Hollywood: Altering Image through Religious Movies
Authors: Witriani Witriani
Published: November 2020

This article discusses the altering image of American Jews in Hollywood movies. Coming to America during the great migration,  mostly from Eastern Europe, this Azkenazic Jews then contributed to the building and transformation of the Hollywood movies as a world icon.  Though quite dominant, Jews are quite careful in this industry. Anti-Semitism, the World War and the Great Depression are some of the things that make Jews uncomfortable about being in the spotlight or talking about their identity among the Christian audience of the movies. However, the condition changed after the Second World War and the civil rights movement in the 1960s. Jews and Judaism later appeared in various representations, which does not only change their image in Hollywood, but also the acceptance of American society broadly. Focusing on the movie, Ben Hur: A Tale of the Christ (1959) as the object of research, the study explores how Jewish people represent themselves through films produced, including the negotiations and changes made as part of the American Jews. Using the theory of Stuart Hall’s Politics of Representation and Critical Discourse Analysis from Fairclough and Leuween as an approach, this work focuses on the analysis of text and images as a sign that represents the Jews and Judaism in the movie. Related to movie as a media construction, the filmmakers are able to reconstruct Jews in different image. Through the movie, the represented Jews are found to have conveyed various messages to the audience about their cultural and religious identity.
La pesadilla de la antropología naturalista: la conciencia
Authors: Anaya González Salvador
Published: November 2020

La antropología filosófica naturalista hace un tratamiento reduccionista de la conciencia que adultera la forma en la cual el ser humano se ha entendido siempre, pero no solo naufraga en su intento de naturalizar lo humano en cuanto humano, sino que también desnaturaliza lo humano en cuanto Ser. La conciencia no puede someterse a los criterios de verdad de la ciencia actual, pero tiene su confirmación en ella misma, porque como nos enseña la fenomenología no hay experiencia más radical que la conciencia.
Platonismo (matemático): diferentes tipos, cómo Roger Penrose lo entiende y lo usa como argumento en contra de la Inteligencia Artificial fuerte
Authors: Heredia González Daniel
Published: November 2020

Roger Penrose es para muchos uno de los pensadores interdiscipli- nares por excelencia en la actualidad. Su crítica a la postura de la Inteligencia Artificial fuerte constituye un bastión tenido en cuenta por la mayor parte de la comunidad dedicada al debate acerca de la IA. En este texto se recogerá uno de los rasgos más filosóficos del pensamiento del autor inglés: el platonismo. En el desarrollo de este trabajo veremos en qué medida Penrose hace una defensa de esta concepción con respecto a las matemáticas y cómo ello establece un punto a favor de su postura en el debate de la IA.

Aim

The aim of the current study was to evaluate P-wave dispersion (PWD) as a predictor of atrial fibrillation in patients with newly diagnosed COVID-19. In addition, the relationship between the PWD and inflammation parameters was investigated.

Methods

A total of 140 newly diagnosed COVID-19 patients and 140 age- and sex-matched healthy individuals were included in the study. The risk of atrial fibrillation was evaluated by calculating the electrocardiographic PWD. C-reactive protein (CRP), white blood cell, neutrophil and neutrophil-to-lymphocyte ratio (NLR) were measured in patients with newly diagnosed COVID-19.

Results

PWD, white blood cell, NLR and CRP levels were significantly higher in the COVID-19 group than the control group. There was a significant positive correlation between PWD and CRP level (rs = 0.510, P < 0.001) and NLR in COVID-19 group (rs = 0.302, P = 0.001). In their follow-up, 13 (9.3%) patients, 11 of whom were in the ICU, developed new atrial fibrillation.

Conclusion

Our study showed for the first time in literature that the PWD, evaluated electrocardiographically in patients with newly diagnosed COVID-19, was prolonged compared with normal healthy individuals. A positive correlation was found between PWD, CRP level and NLR. We believe that pretreatment evaluation of PWD in patients with newly diagnosed COVID-19 would be beneficial for predicting atrial fibrillation risk.
Asymptotic behavior of solutions to barotropic vorticity equation on a sphere
Authors: Skiba Yuri N.
Published: November 2020

The behavior of a viscous incompressible fluid on a rotating sphere is described by the nonlinear barotropic vorticity equation (BVE). Conditions for the existence of a bounded set that attracts all BVE solutions are given. In addition, sufficient conditions are obtained for a BVE solution to be a global attractor. It is shown that, in contrast to the stationary forcing, the dimension of the global BVE attractor under quasiperiodic forcing is not limited from above by the generalized Grashof number.

Authors: Issaad F. , Maafa A. , Rozale H. , Boukli Hacene M.A. , Bouabça A.
Published: November 2020

In this paper, we have studied the electronic, elastic and thermoelectric properties of the half-Heusler LiCrZ (Z = C, N, Si, and P) materials in Type II phase, in this structure the atomic occupations are X (1/2,1/2,1/2), Y (0,0,0) and Z(1/4,1/4,1/4). The ferromagnetic state of Type II structure was found to be the most stable phase for all studied alloys. After calculating the elastic constants, we found out that the conditions of mechanical stability were verified only for LiCrSi and LiCrP alloys in Type II phase, at both equilibrium a0 and half metallic ahm lattice constants, which indicates that these two compounds can be synthesized experimentally. We should also mention that the half metallic behavior in Type II structure, for LiCrSi and LiCrP compounds, was obtained by straining the equilibrium lattice constants by 2% and 6%, respectively. At ahm, these two systems were identified to be true half metals due to their complete spin polarization and integer value of total magnetic moment. These last ones have reached 3μB per unit cell when Z = Si, and 4μB when Z = P. Using the mean field approximation (MFA), the Curie temperatures of Type II structure were also determined, where the values are estimated to be 456.2 K and 302.8 K, respectively. Finally, the thermoelectric performance has been explored by the classical Boltzmann theory. At low temperatures, the figure of merit has reached 0.73 and 0.93 for LiCrSi and LiCrP, respectively. The considerable ZT values and all calculated physical properties make these two systems promising candidates for thermoelectric applications.

Authors: Izgi Ayça , Kaya Eylem , Kale Ediz , Zortuk Mustafa
Published: November 2020

Background/Aim: The aim of this study was to evaluate the bond strength of glass ceramic inlay system using 2 antibacterial adhesive luting protocols with 2 cementation techniques to bur-cut dentin. Material and Methods: Class I inlay cavities with 6-degree occlusal divergence and size of 6-, 3and 2-mm in length, width and depth, were prepared on extracted human molars, randomly assigned to 2 main groups; each to 1 cementation technique, with or without immediate-dentin-bonding (IDB or NIDB) further divided into 3 subgroups; 2 to 2 antibacterial luting protocols, traditional (T) and experimental (E); and 1 to a control (C) group. In group IDBT, IDB-E and IDB-C dentin bonding was applied immediately after cavity preparation. In group NIDB-T, NIDB-E and NIDB-C dentin bonding was applied just before cementation of the restorations. The cavities in IDB-T and NIDB-T were treated with 2% chlorhexidine-digluconate (CHX) prior to dentin bonding application. The cavities in IDB-E and NIDB-E were treated only with dentin bonding system containing MDPB (12-methacryloyloxydodecylpyridinium bromide) active monomer featuring antibacterial effect. IDB-C and NIDB-C served as control. Dual-cure adhesive resin cement was used for the cementation of Lithium disilicatebased ceramic inlay restorations. Fourteen test specimens per group were prepared for microtensile testing and consecutively subjected to tensile load at a crosshead speed of 1 mm/min. The mode of failure was observed under SEM and evaluated for each group. The Kruskal-Wallis test was used to investigate the statistical difference between groups (a=0.05). Results: The microtensile load was 5.96 MPa (median: 5.99 MPa) for IDB-T, 7.23 MPa (median: 7.55 MPa) for IDB-E, 6.68 MPa (median: 6.56 MPa) for IDB-C, 7.24 MPa (median: 7.20 MPa) for NIDB-T, 6.98 MPa (median: 6.30 MPa) for NIDB-E, and 7.02 MPa (median: 6.99 MPa) for NIDB-C, with no statistical difference between the groups (p>0.05). SEM monitoring for mode of failure revealed either cohesive (within resin cement) or adhesivecohesive (mostly within resin cement along with partially involved areas between resin cement and ceramic restoration) character. Conclusions: Within the limitations of the current study, none of the tested antibacterial luting protocols with either cementation technique was found to be superior in terms of bond strength.

Authors: Abed Musab Sabah
Published: November 2020

With the intention of providing a balance between the disposal of wastes generated from incineration processes and mitigate the emissions from industrial activities, the reuse of incineration waste as alternatives to conventional binders would offer a sustainable solution to reduce their environmental impact. This study aims to experimentally investigate the effect of firewood, ash (FWA) and ordinary Portland cement on some of the geotechnical properties of low plastic clayey soil (CL). The experimental program was introduced by partial replacement of ordinary Portland cement with firewood ash (FWA) up to 10 % with an increment of 2 %. A series of unconfined compressive test (UCT) and Atterberg limits test were performed. The results indicate that plasticity characteristics are affected by the addition of both cement and (FWA). Also, the results showed that the unconfined compressive strength increases for all replacement levels in comparison with the plain clay sample. The term deformability index (DI) also discussed with respect to different replacement level. The 70.61 % pozzolanic activity index indicates that (FWA) is a good pozzolan in accordance with ASTM C 618 specification. Finally, three modes of failure were detected which varying in accordance with the proportion of replacement.

Published: November 2020

Introduction. Chronic obstructive pulmonary disease (COPD) is the third leading cause of death in the world among chronic diseases. The article discusses the relationship between the quality of life of patients with COPD and the presence of diseases associated mainly with hypertension, diabetes and hyperlipidemia. The examination includes subjective and holistic assessment of the patient’s health condition, which allows to notice any disorders and deficits in the functioning of patients with this disease.

Aim. The aim of the study was to determine the quality of life of patients with chronic obstructive pulmonary disease depending on the comorbidities.

Material and methods. The study included 319 COPD patients treated in the Lung Diseases Clinic with chronic obstructive pulmonary disease. The study was conducted using a diagnostic survey method and analyzing medical records. The research tool assessing patients quality of life was the SGRQ questionnaire (Saint George Hospital Questionaire).

Results. Respondents who had a myocardial infarction had a slightly lower quality of life in the “Impact on life subscale” (p=0.047). It was noted that patients with hypertension had a lower quality of life in the domain of “Activity” (p<0.05) and “Impact on life” (p<0.001). However, with hyperlipidemia, a lower quality of life was noticeable in the “Symptoms” (p<0.001) and “Impact on life” subscale (p=0.002).

Conclusions. Exacerbation of symptoms in the course of chronic obstructive pulmonary disease, a history of myocardial infarction, hypertension and hyperlipidemia are significantly related to the decreased quality of life of patients. Prevention of these civilization diseases can prevent deterioration of the quality of life of patients.

Published: November 2020

A technology for producing gold films on the surface of fabric materials has been developed, which provides for preliminary wetting of the fabric product with aqueous solutions of gold (III) chloride. In this case, a sorption layer of gold chloride is formed on the surface of fabric materials. Then, when drying these products under sunlight, physicochemical and photochemical processes occur, leading initially to the formation of monovalent gold chlorides, which, having semiconductor properties, provide the release of elemental gold. After washing of by-products on the surface of the material remains an ultra-thin film of gold, which has a sufficiently strong grip on the base. Since the proposed technology does not require special equipment it can be used to apply functional films of gold on various products of technical, household and medical purposes.

Published: November 2020

Early diagnosis and adequate surgical treatment are the key factors for the course of the laryngeal cancer of the head and neck and the outcome of the surgical treatment in these patients. The aim of the paper is to compare the characteristics of the surgically treated patients with the larynx carcinoma who developed recidivism to those who did not. The study was done as a retrospective observational case-control study on a total of 90 patients with the laryngeal cancer who had been successfully operated on and whose cases had been followed over a period of at least five years after the surgery. After that, they were shorted into two groups based on the development of recidivism, and clinical characteristics of the patients with and without recidive disease were compared. 19 out of 90 patients developed recidivism. Maximum diameter of the tumour was significantly larger in patients without local recidivism. In patients without local recidivism, most common clinical stages were 3 and 4 (32.4%, 40.8%, respectively), whereas in patients with local recidivism stages 1 and 2 were the most common (47.7%, 26.3%, respectively). The average time to disease recurrence in the 19 patients who developed local recidive disease was 648.10 (384.67-911.54) days. Pathohistological analysis showed that samller the size of the tumour and lower T grade at the moment of surgery are precautionary factors for further monitoring of patients with laryngeal cancer.

Abstrakt

W literaturze naukowej od wielu lat szeroko omawiana jest tematyka zanieczyszczeń powietrza. W miastach w sytuacji długotrwałego utrzymywania się przekroczeń norm jakości powietrza istotne staje się zagadnienie zrównoważonego rozwoju tkanki urbanistycznej. Celem artykułu jest ocena wpływu uwarunkowań przestrzennych na terenie Krakowa na rejestrowane wysokie wartości stężeń zanieczyszczeń powietrza pyłem PM10 w 2017 r. Analizę przeprowadzono, wykorzystując dane pomiarowe Wojewódzkiego Inspektoratu Ochrony Środowiska w Krakowie oraz niezależnej sieci czujników Airly. Na podstawie przetworzonych materiałów scharakteryzowano stan jakości powietrza w mieście. Analiza liczby dni z przekroczeniami 24-godzinnego dopuszczalnego poziomu PM10 pozwoliła wskazać obszary na terenie miasta najbardziej narażone na wysokie wartości stężeń niebezpiecznej substancji. Na podstawie wyników wskazano, że w skali lokalnej występują źródła punktowe, liniowe i powierzchniowe mające wpływ na stan aerosanitarny Krakowa. Przeanalizowano również jedno z narzędzi walki o czyste powietrze w mieście, tj. zapisy obowiązujących w wybranych obszarach miejscowych planów zagospodarowania przestrzennego. Zestawiając ustalenia aktów prawa miejscowego z wynikami zaprezentowanej liczby dni z przekroczeniami dopuszczalnych dobowych stężeń dla analizowanych obszarów, stwierdzono, iż nie w każdym przypadku ogólne zapisy są w stanie ograniczyć nadmierne zanieczyszczenia.

Authors: Kargovskaia Elena , Kuznetsova Viktoriia
Published: November 2020

This article is dedicated to the events that received the name of Guna Revolution and led to the autonomy of Comarca Guna Yala that belongs to the Republic of Panama. Guna Indians are one of the few peoples of the American Continent who were able to preserve integrity of their land, their authenticity, traditions, culture and beliefs, although it took them enormous efforts. The goal of this research consists in examination of causes that led to the rebellion, as well as its consequences for the Guna people. The authors of attempt to reconstruct the events and determine the crucial factor that affected successful outcome of the revolt. The scientific novelty is defined by the fact that the history of Guna Indians of the Republic of Panama alongside the events related to their struggle for the autonomy and self-identification did not receive due coverage within the Russian scientific publications. In the current era of globalization, which blurs the boundaries and differences, the preservation of authenticity and integrity of small, and often large, ethnic groups is more relevant than ever. One of the authors was able to visit Comarca Guna Yala and get acquainted with the lifestyle, culture and traditions of its inhabitants, as well as listen to their perspective on the historical events of 1925, which Guna Indians carefully preserve in their folk tradition of chants that sound on the sessions of Guna General Congress.

Published: November 2020

The subject of this research is educational literature as a source for reconstruction of collective historical representations on Russian history in of the late XVIII century. The author analyzes the state of educational system in the Russian Empire of the second half of the XVIII century, and characterizes the measures taken by the government on formation of multibranch network of elementary and secondary educational institutions. Special attention is given to the process of creation of school textbook on Russian history with personal contribution of Catherine the Great. The conclusion is made that the second half of the XVIII century became the time of formation of first educational texts for broad audience dedicated to the history of Russia. During this period, the government order had a determining influence, and the opinion of the ruler had direct impact on the content of textbooks. Within the framework of school program, preference was given to nonconfrontational version of the past, which did not touch upon the “sore points” of national memory. The pantheon of heroes of the national memory has not yet been formed in the educational literature of the late XVIII century, and thus, the objects for research (heroes and events) slightly differ from the textbooks of the XIX – early XX centuries. Despite this fact, the school textbooks of the late XVIII century, significantly impacted the school curriculum on history and development of collective representations on the past in Russia of the XIX-early XX centuries.

Introduction. Nevus sebaceous of Jadassohn (synonym: nevus of the sebaceous glands) (NSG) presents the congenital malformation of the skin with possible transformation into benign or malignant tumors during the adolescence or adulthood. Commonly appeared on the scalp or neck NSG is frequently concern with cosmetic problems making patients look for opportunities for its removal. Surgical removal of the NSG is related to an elevated risk of scarring. Using ablative lasers has proven to be effective in the removal of small NSG. However, the removal of medium and large NSG with ablative lasers was reported to be linked with a high risk of scarring and recurrence. The removal of the medium-sized NSG with a copper vapor laser (CVL) is described here for the first time.
Case report and procedure. Laser removal of NSG (linear sized of 27 mm) was performed in a 25-year-old female patient with Fitzpatrick skin type II during eight CVL treatments. Laser settings were selected as follows: the average power of 1 W at the power ratio of 3:2 radiation at a wavelength of 511 and 578 nm. Pulse duration 20 nanoseconds, reprate 16.6 kHz, exposure duration 200 ms, and the light spot's diameter on the skin 1 mm.
Results. After 8 procedures, the skin in the area of the removed NSG acquired a natural color and appearance. During 24 months of follow-up, there was no hyperpigmentation or signs of scars in the irradiated area. No relapses were observed for 24 months after the CVL removal of NSG.
Conclusion. The application of non-ablative CVL removal of NSG ensured a desired cosmetic result without side effects.
