A novel method for development of post-quantum digital signature schemes
Authors: Moldovyan Dmitry , Moldovyan Alexandr , Moldovyan Nikolay
Published: December 2020

Introduction: Development of post-quantum digital signature standards represents a current challenge in the area of cryptography. Recently, the signature schemes based on the hidden discrete logarithm problem had been proposed. Further development of this approach represents significant practical interest, since it provides possibility of designing practical signature schemes possessing small size of public key and signature. Purpose: Development of the method for designing post-quantum signature schemes and new forms of the hidden discrete logarithm problem, corresponding to the method. Results: A method for designing post-quantum signature schemes is proposed. The method consists in setting the dependence of the publickey elements on masking multipliers that eliminates the periodicity connected with the value of discrete logarithm of periodic functions constructed on the base of the public parameters of the cryptoscheme. Two novel forms for defining the hidden discrete logarithm problem in finite associative algebras are proposed. The first (second) form has allowed to use the finite commutative (non-commutative) algebra as algebraic support of the developed signature schemes. Practical relevance: Due to significantly smaller size of public key and signature and approximately equal performance in comparison with the known analogues, the developed signature algorithms represent interest as candidates for practical post-quantum cryptoschemes.

Published: December 2020

Introduction: Electroencephalograms contain information about the individual characteristics of the brain activities and the psychophysiological state of a subject. Purpose: To evaluate the identification potential of EEG, and to develop methods for the identification of users, their psychophysiological states and activities performed on a computer by their EEGs using convolutional neural networks. Results: The information content of EEG rhythms was assessed from the viewpoint of the possibility to identify a person and his/her state. A high accuracy of determining the identity (98.5–99.99% for 10 electrodes, 96.47% for two electrodes Fp1 and Fp2) with a low transit time (2–2.5 s) was achieved. A significant decrease in accuracy was detected if the person was in different psychophysiological states during the training and testing. In earlier studies, this aspect was not given enough attention. A method is proposed for increasing the robustness of personality recognition in altered psychophysiological states. An accuracy of 82–94% was achieved in recognizing states of alcohol intoxication, drowsiness or physical fatigue, and of 77.8–98.72% in recognizing the user's activities (reading, typing or watching video). Practical relevance: The results can be applied in security and remote monitoring applications.

Published: December 2020

Introduction: There is growing evidence of a connection between tumor clonal profile and its clinical impact. However, there is a lack of a feasible and reliable method for clonal profiling in actual clinical practice. Myelodysplastic syndrome is a clonal hematopoietic stem cell disorder characterized by morphological dysplasia, cytopenia and a high risk of evolution to acute myeloid leukemia. The clinical outcome of myelodysplastic syndrome is greatly heterogeneous; therefore, specific examination of clonal profiles is needed to resolve the prognosis of patients with such complex disorders. Purpose: Development of a pipeline specifically for determining the clonal profiles in patients with myelodysplastic syndrome on the basis of target next-generation sequencing data. Results: The pipeline was developed and evaluated on a set of 35 patients with high-risk myelodysplastic syndrome. It is possible to use the target sequencing data in order to assess the heterogeneity of clonal profiles and characterize their genetic features. This approach allows you to identify the consistency between a specific individual profile and the disease prognosis, which can be critical for the treatment decision. Herein, the characterization and analysis of clonal profiles are presented. Practical relevance: The information about relation patterns between clonal profile characteristics (number of subclones, mutations-per-clone rate) and clinical outcome can be used by doctors in current practice for a more accurate therapy selection depending on the identified individual specificity of the disease.
Okul Öncesi Öğretmenlerinin Sınıf İçi Etkileşim Örüntülerinin İncelenmesi: Sınıf Söylemi Analizi Yaklaşımı
Authors: BAŞALEV Serenay , SOYSAL Yilmaz
Published: December 2020

Bu çalışma iki okul öncesi öğretmeninin sınıf içi öğretimlerinde ortaya çıkan etkileşim örüntülerinin incelenmesini amaçlamaktadır. Etkileşim örüntüleri üçlü bir diyalog yapısı ile gözlemlenebilir. Öğretmen bir soru ile diyaloğu başlatır, öğrenciden öğretmen sorusuna cevap sağlanır ve öğretmen verilen cevabın doğru/makul olup olmadığına karar verebilir, ya da cevabı genişleten/değiştiren ek açıklamalar yapabilir ya da cevapla ilgili başka bir soru sorabilir. Durum çalışması olarak tasarlanan bu araştırmanın katılımcılarını iki okul öncesi öğretmeni ve 52 okul öncesi öğrencisidir. Çalışmanın veri setini sınıf içi uygulamaların video kayıtları (n = 17, 302 dakika) oluşturmaktadır. Öğretmenler, araştırmacılar tarafından tasarlanan ve sınıf içi diyaloglara imkân sağlayan hikayeleştirilmiş ikilemleri öğrencileri ile tartışmışlardır. Öğretmenlerin söylemleri sosyokültürel söylem analizinin bir kolu olan sistematik gözlem yöntemi ile analiz edilmiştir. Sistematik gözlemlerde analiz birimi öğretmenlerin cümleleridir. Her bir öğretmen cümlesi hem teori hem de veri temelli olarak bu çalışma kapsamında geliştirilen Üçlü Etkileşim Örüntüsü Kodlama Kataloğu aracılığı ile kodlanmıştır. Öğretmenlerin üç farklı tipte etkileşim örüntüsünü farklı frekanslarla sergilediği görülmüştür: Başlat-Cevapla-Değerlendir (BCD), Başlat-Cevapla-Açıkla (BCA) ve Başlat-Cevapla-Takip Sorusu (BCT). Öğretmenlerin sıklıkla takip sorularını kullandığı (BCT) ve aynı zamanda sınıf söyleminde olgu ve durumları açıklayıcı (BCA) ya da öğrenci ifadelerini değerlendirici (BCD) söylemler sergilediği de belirlenmiştir. Ek olarak, öğretmenlerin diyaloglar esnasında hangi tür konuşma ikilisini; T-S (öğretmen-öğrenci) ve/veya S-S (öğrenci-öğrenci), tercih ettiği belirlenmiştir. Her iki öğretmenin de sınıf söylemine yoğun müdahalelerinin olduğu ve öğrenci – öğrenci arasında yaşanan diyalogların kısıtlı olduğu görülmüştür. Elde edilen bulgular doğrultusunda öğretmenlerin sınıf içi konuşmalarında oluşan ve entelektüel çıktıları etkileyebilen etkileşim örüntülerine yönelik bilinçli pedagojik-söylemsel farkındalığının geliştirilmesi için çeşitli önerilerde bulunulmuştur.
Az emberi jogok mint politikai doktrína a lelkiismereti szabadság példáján
Authors: Balázs Zoltán
Published: December 2020

Ebben a tanulmányban amellett érvelek, hogy az emberi jogok doktrínája lényegileg politikai, nem pedig erkölcsi vagy filozófiai természetű. Miután bevezetem a politikai doktrína fogalmát, néhány klasszikus szerzőt idézek, Locke-tól Burke-ig, Vitoriától Paine-ig, Milltől Stephenig, hogy bemutassam, miként alakult ki a doktrína a maga sajátos politikai kontextusában. Amellett is érvelek, hogy bár a 19. században a Katolikus Egyházat tartották a lelkiismereti szabadság (értelemszerűen az egyik legalapvetőbb jog) legádázabb ellenfelének, az Egyház teológiai hagyománya valójában ambivalens volt. A lelkiismereti szabadságot természetes adottságként kezelte, de az emberi természet megrontottságának jól ismert teológiai argumentuma miatt bizalmatlanul tekintett ennek az adottságnak a jogként való körülbástyázására. Ezzel azonban a doktrína politikai jellegét erősítette meg. Azt is bemutatom, hogy ezt a ’jogot’ a kezdetektől fogva bizonyos (többnyire Egyházon belüli) intézmények (egyetemek, jogi eljárások) formalizálták. A nyugati világ masszív demokratizálódása során ezeknek a jogoknak az egyének váltak az intézményi formáivá. Ezt igazolja, hogy az egyének leírása során számos politikai fogalmat használunk (szuverenitás, önrendelkezés, önkormányzás). Az emberjogi, jogvédő mozgalmak és szervezetek jelentős politikai ereje a mögöttük fölépített ideológiai elkötelezettségek politikai jellegét szintén megerősíti. Így az emberi jogok megalapozására és megvédésére tett erkölcsi és filozófiai erőfeszítések ellenére ezek a jogok a maguk politikai eredete és mai szerepe miatt politikai doktrínának nevezhetők.
Kereszténység és emberi jogok – az emberi méltóság nézőpontjából
Authors: Balogh Zsolt Péter
Published: December 2020

A tanulmány bizonyítani igyekszik, hogy a vallási meggyőződéssel élő embert nem távolítani kell az emberi jogok rendszerétől, hanem épp ellenkezőleg, közelíteni kell felé. Az emberi jogok a Teremtő adta emberi szabadságból erednek, minden jog mélyén megtalálható az emberi méltóság. Az emberi jogok az embertől elválaszthatatlan olyan természetes és elidegeníthetetlen jogok, amelyeknek tápláléka a keresztény szabadságeszme is. A tanulmány foglalkozik a személyiségvédelemmel, érinti a magánszféra védelmét, az egyenlőség problémáját, valamint arra a megállapításra jut, hogy az emberi jogok alatt bizonyos szociális jogokat is érteni kell a keresztény szellemű megközelítés alapján.
Az elveszett Paradicsom keresése : Posztkeresztény válság vagy keresztény társadalom?
Authors: Kis Norbert
Published: December 2020

A tanulmány felidézi a keresztény vallás előtti ember találkozását a keresztény vallás tanításaival, majd nyomon követi a kereszténység gyengülésének okait, azaz a „természet Istenének” (deizmus) reneszánszát a filozófiában és a művészetekben. A keresztény szabadság a felvilágosodás korában még alkotóerő, azonban a vallással szembeni szekularizáció kísérlete is elindul, és két évszázadon át napjainkig bomlasztja a nyugati kultúra organikus szöveteit. A tudomány holtpontra jutott, mert továbbra sincs bizonyítéka az élet eredetére, és nincs válasza az emberi élet „céljára”. Kihalt-e az emberi közösség ösztönös igénye a transzcendens válaszokra? Kiégett és megérett-e a nyugati ember arra, hogy újra Istenben keresse a közösséget építő hitet és célokat? Elbukik-e a következő évtizedekben a szekularizált társadalom kísérlete? Elvesztik-e életképességüket a semleges társadalmak? Milyen lehet a kereszténység tézise és a szekularizáció antitézise nyomán születő 21. századi „szintézis”? Milyen jelek utalnak arra, hogy a nyugati kultúra közösségei megtalálják a keresztény vallás modern vagy posztmodern formáját? Következtetésünk, hogy a szekularizált szabadságeszmény és a politikai ideológiák sem tudtak, és a tudomány sem tudott közösségépítő és közösségmegtartó erővé válni. A vallási hagyomány mint közösségépítő erő és közösségi őskép tartósan nem helyettesíthető. Kétszáz év kétségbeesett útkeresés után a keresztény vallás újjászületése lehet a kiút a nyugati ember válságából. Napjainkban a konzervatív politika, benne a nemzetpolitika és a nemzeti valláspolitika erősödése is ebben a történelmi áramlásban értelmezhető. A konzervativizmus felismeri, hogy a jézusi tanítások, a keresztény istenelv 21. századi üzenetekkel újra felébresztheti az „örök igazságok” hitét, az elveszett Paradicsom keresését, és újra nagy közösségi erővé válhat.

Published: December 2020

During pregnancy there are physiological and psychological changes that can cause discomfort such as leg cramps, difficulty breathing, back pain, depression, anxiety and sleep disorders. The prevalence of low back pain is around 60-80% which can lead to strain on the ligaments and fatigue in the abdominal muscles, as well as balance disorders. This will lead to disruption of activities during pregnancy, such as difficulty walking and sleep disturbances. To assess low back pain and sleep quality among pregnant women: cross sectional study. Cross-sectional data were collected by 37 pregnant women with inclusion criteria were third trimester pregnant women, willing to be a respondent, with normal blood pressure, and have not received any medication related sleep disorder. They completed the Pittsburgh Sleep Quality Index (PSQI) and Rolland-Morris Disability Questionaire (RDQ), statistical analysis was conducted using Pearson Correlation Product Moment. Research was conducted in Semarang and Kudus. Sleep quality among pregnant women demonstrated significanly poor overall sleep quality with PSQI score (mean 8.70 ± 3.511) and RDQ score (mean 8.97 ± 6.414). There was moderate correlation between low back pain with sleep quality (r correlation = 0.558). Low back pain have correlation to increase or decrease sleep quality among preganant women.

Claustra Alpium Iuliarumjedan je od najvećih arhitektonskih kasnoantičkih vojnih pothvata na području današnjih Hrvatske i Slovenije, koji je zbog njegove raspro-stranjenosti kroz šumom obrasla područja dviju država teško zaštititi, očuvati i rabiti u turističke svrhe.

Potječe li kasnoantički portret muškarca iz Tarsatike? Još jednom o pitanju provenijencije rimskih spomenika iz fundusa Pomorskoga i povijesnoga muzeja Hrvatskog primorja Rijeka i zbirke Lavala Nugenta
Authors: Karković Takalić Palma , Rabar Kerol
Published: December 2020

U radu se raspravlja o provenijenciji kasnoantičkoga muškog portreta, jedinoga primjera rimske kamene portretne plastike u zbirci Pomorskoga i
povijesnoga muzeja Hrvatskog primorja Rijeka. S ciljem utvrđivanja njegova podrijetla donosi se kratak pregled povijesti toga muzeja, koji nastaje kao rezultat ujedinjenja dviju muzejskih institucija: riječkoga Musea civica i sušačkoga Gradskog muzeja. Obje su se institucije od utemeljenja 1893., odnosno 1933., nekoliko puta selile do objedinjavanja
u Guvernerovoj palači 1948. Ne čudi, stoga, što su brojnim umjetninama današnje zbirke Pomorskoga i povijesnoga muzeja Hrvatskog primorja Rijeka izgubljeni podaci o mjestu, okolnostima nalaza ili donaciji. Pridruženi su joj i neki spomenici koji su pripadali Muzeju Nugent. Taj je muzej funkcionirao između 1843. i sedamdesetih godina 19. stoljeća na
Trsatu, a činili su ga rimski spomenici koje je grof Laval Nugent von Westmeath iskopao u talijanskome Minturnu i kupio na tržištima antičkih i
drugih umjetnina sjevernoga Jadrana. Dio zbirke je ukinućem toga muzeja
prodan Narodnom, danas Arheološkom muzeju u Zagrebu. Iz toga razloga Ante Rendić-Miočević drži da je i riječka kasnoantička glava pripadala Nugentovoj zbirci, odnosno da je pri prodaji rimskih kipova u Zagreb jedina ostala u Rijeci. Analizom i usporedbom svih nama poznatih popisa Nugentovih antičkih spomenika, poput onih E. Wolffa, B. Biasoletta, R. Schneidera i J. Brunšmida, nismo pronašli naš kasnoantički portret. Smatramo, stoga, da bi se njegovo podrijetlo moglo povezati s Tarsatikom
s obzirom na intenzivan razvoj toga grada upravo u kasnoantičkom razdoblju.

Published: December 2020

The aim of the research was to construct and validate The Parental Assessment Questionnaire for Children's Emotional Competence (URPEKD). The factorial structure, reliability, validity and sensitivity of the whole questionnaire, as well as the discriminability of individual items
were checked, and the best items selected to be captured by the measurement construct were selected. Factor analysis resulted in a two-factor solution that explained 59.845 % of the total variance. The first factor that is saturated with eight items is called The perception, understanding and expression of one's emotions. The second factor that is saturated with six items is called Perception, understanding, and expression of others' emotions. The reliability of the entire scale, as well as its subscales is satisfactory. The construct validity of the URPEKD instrument was verified by its association with a similar instrument for students - UEK-45 (Takšić, 2002). There is a significant correlation between the stated factors of both questionnaires indicating satisfactory validity. The instrument is suitable for the use of measuring primary school children’s emotional competence by their parents.

Tragovi prapovijesnih pokapanja ljudi u špiljama dubrovačkoga područja
Authors: Perkić Domagoj , Novak Mario
Published: December 2020

U špiljama i drugim speleološkim objektima kao arheološkim lokalitetima ponekad se nalaze ostaci ljudskih kostiju. Za većinu takvih špilja može se pretpostaviti kako predstavljaju mjesto ukopa, odnosno izvjestan oblik nekropole, mada je ponekad riječ i o slučajnome, pojedinačnom nalazu. Na osnovi okolnoga arheološkog konteksta ili provedenih dodatnih radiokarbonskih analiza na uzorcima kostiju, zaključujemo kako je uglavnom riječ o prapovijesnim razdobljima. Sličnu situaciju nalazimo na širem dubrovačkom području gdje su analizirane špilje na poluotoku Pelješcu (špilja Crno jezero u Ponikvama i špilja Gudnja u blizini Stona), Dubrovačkome primorju (Zmajeva peć u Čepikućama) te zapadnome dijelu grada Dubrovnika (Vilina špilja iznad izvora Omble, Močiljska špilja iznad Mokošice i Kukova peć u Brsečinama). Kod pojedinih ljudskih osteoloških nalaza u navedenim špiljama obavljena je i bioarheološka analiza, što upotpunjuje još uvijek slabo poznavanje korištenja špilja kao mjesta pokapanja u prošlosti.

Published: December 2020

The experiment was conducted at the Agronomy Field Laboratory of Bangladesh Agricultural University during the period from July to December 2017 to evaluate the effect of barley crop residues on weed management and yield of transplant aman rice. The experiment consisted of three time of crop residue application viz. one week before transplanting, at the time of transplanting, at one week after transplanting and five doses of barley crop residues such as no crop residues, barley crop residues @ 0.5 t ha-1, barley crop residues @ 1.0 t ha-1, barley crop residues @ 1.5 t ha-1, and barley crop residues @ 2.0 t ha-1. The experiment was laid out in a split plot design with three replications. Weed population and weed dry weight were significantly affected by the dose and time of barley crop residues application. The minimum weed growth was noticed with the application of barley crop residues @ 2.0 t ha-1 at one week after transplanting and the maximum one was observed in no crop residues treatment at one week before transplanting. The highest values of percent weed inhibition was found with the application of barley crop residues @ 2.0 t ha-1 which were 48.13%, 41.39%, 39.71%, 39.88% and 38.73% for panikachu (Monochoria vaginalis), shama (Echinochloa crusgalli), chesra (Scirpus juncoides), amrul (Oxalis corniculata) and sabujnakful (Cyperus difformis), respectively. Rice grain yield and the yield contributing characters produced by the application of crop residues at one week before transplanting was the highest among different times of application and the highest reduction of rice grain yield was obtained in no crop residue treatment. The highest number of effective tillers hill-1, number of grains panicle-1, 1000-grain weight, rice grain and straw yields were observed when barley crop residues were applied @ 2.0 t ha-1 at one week before transplanting.  Results of this study indicate that application of barley crop residues @ 2 t ha-1 at one week before transplanting showed the maximum suppression of weed growth. Therefore, barley crop residues might be used as an alternative tool for weed management in transplant aman rice.

Distribution of juvenile American horseshoe crabs Limulus polyphemus in the Great Bay Estuary, New Hampshire, USA
Authors: Cheng H , Chabot CC , Watson WH
Published: December 2020

In order to effectively manage a fishery, it is important to know the essential habitats used by all life history stages of the species being managed. However, this is often a challenge for animals such as the American horseshoe crab Limulus polyphemus, whose juvenile stages are difficult to find and quantify. Visual surveys and suction sampling have been used in previous studies, but in the Great Bay Estuary, New Hampshire, they are less effective, and so little is known about the habitats occupied by juvenile horseshoe crabs in this area. To fill this knowledge gap, we used SCUBA-dive surveys to locate juvenile horseshoe crabs. We found them on subtidal and some intertidal mudflats in the upper regions of the estuary, both adjacent to, and at some distance from, known spawning beaches. However we did not find them in either intertidal or subtidal areas adjacent to spawning beaches just 1-2 km closer to the coast. These data should be useful for future conservation efforts designed to protect essential horseshoe crab habitats in the Great Bay and other similar estuaries.

The structure of soft contact lens users and the incidence of papillary conjunctivitis in the analyzed groups according to the data of “Krugozor” ophthalmology clinic
Authors: Dubovtseva O. V. , Bakalova N. A.
Published: December 2020

Introduction. Vision correction by contact lenses is one of the most common and effective methods for correcting refractive errors in children and adults. Compliance with rules of soft contact lenses (SCLs) wearing is one of the most important conditions for a safe use, while violation of compliance is usually the main cause of complications.

Purpose. To study the structure of contact lens wearers by ametropia and lens wearing time as well as to determine the relationship between the incidence of giant papillary conjunctivitis (GPC) with lens wear time and overwear time.

Material and methods. A retrospective analysis of 1 000 records (1 000 patients) of patients who underwent vision correction by SCLs in “Krugozor” ophthalmology clinic in the year 2019 was carried out. Mean age of patients was 24.95 ± 8.62 years. Age, type and degree of ametropia, material (hydrogel, silicone hydrogel or biocompatible hydrogel), lens replacement schedule, presence of complications, lens overwear time and daily wear time were taken into account.

Results. Most SCLs users are patients between 21 and 30 years old (47%) who have a moderate degree of ametropia (52%). Most of them (46%) preferred monthly replacement SCLs, 29% – bi-weekly replacement SCLs, 9% preferred daily replacement lenses, while quarterly replacement lenses were used by 16%. Only 26.9% of SCL users complied with the instructions for lens wear, while for 29.4% of them lens overwear time amounted to up to 14 days, for 34.1% – up to 28 days, and for 9.6% – more than 1 month. More than half (56%) of patients mainly wore SCLs during 16 hours a day, one in five (22.7%) used SCLs during 12 hours a day, and 12.6% – up to 20 hours a day. 8.7% wore lenses during up to 7 days. The incidence of GPC in patients who did not comply with replacement schedule and were overwearing lenses was significantly higher (38.71%) than in patients who followed the replacement schedule (3.21%).

Conclusion. More than half of the users comprised young people with a moderate degree of myopia. The most commonly used SCLs were monthly replacement. It was discovered that only one in four wearers followed recommendations of manufacturers and replaced lenses on time. Lens overwear may lead to a development of a giant papillary conjunctivitis (GPC).

Для обсуждения вопроса работы оптометристов, на мой взгляд, прежде всего надо понимать, что мы хотим – т. е. провести анализ дел, на его основе определить текущие и стратегические цели, а также методы их достижения. Отсутствие единства в этих вопросах создает недопонимание и противоречивость мнений.

In the review data concerning modern methods of endoscopic treatment of colonic strictures are presented.

Relevance of this problem, reasons for the development, clinical picture and methods of endoscopic procedures for strictures are presented in detail.

The analysis of Russian and foreign literature with an assessment of the effectiveness and feasibility of various methods of treatment of strictures has been done. Despite the variety of ways of existing methods of stricture’s treatment, there are still no evidence-based data on the efficiency and safety of various endoscopic approaches.

Thus, there are a number of unresolved topical issues that require further research.

AIM: to determine the incidence of accompanying cytomegalovirus infection (CMVI) in patients with moderate and severe ulcerative colitis, and also to determine the value of diagnosis and treatment of this infection in that category of patients.

PATIENTS AND METHODS: the study included 67 patients with severe or moderate ulcerative colitis. The colonoscopy with biopsy with definition of cytomegalovirus DNA by polymerase chain reaction (PCR) was done in all the patients. The patients without virus (CMV negative group) received therapy according to the current clinical recommendations. The patients with virus (CMV positive group) had antiviral therapy by ganciclovir in addition to the standard therapy. The viral load in colonic biopsy of those patients was evaluated before the treatment and on the 19-21 st therapy days. In case of patient state deterioration and inability to continue the conservative treatment, colectomy was done. The success of therapy in both groups was assessed by the colectomy rate during hospitalization.

RESULTS: the incidence of severe and moderate ulcerative colitis combination with cytomegalovirus infection was 43.2%. The previous treatment did not influence on the probability of virus detection. Acute attacks of ulcerative colitis were found significantly more often in the CMV-positive group than in the CMV-negative group (20% vs 2.6%, respectively) (р=0.02). The efficacy of the antiviral therapy was 69%. All the patients who responded to the antiviral therapy did not undergo surgery. Failure of the antiviral therapy in the patients with associated cytomegalovirus infection significantly increased the colectomy rate (0 – in the patients who responded to the antiviral therapy vs. 22.2% of those who did not respond).

CONCLUSION: the study showed 43% of cases moderate and ulcerative colitis goes with CMVI persistence. CMVI is the resistance factor for conservative treatment. The specific antiviral therapy in addition to the conservative treatment for this category of patients ameliorates the treatment results and prognosis.

Published: December 2020

AIM: to evaluate the early and long-term results of emergency two-stage surgical procedures in patients with sigmoid colon cancer complicated by decompensated bowel obstruction.

PATIENTS AND METHODS: the cohort study included 112 patients with sigmoid colon cancer complicated by bowel obstruction that underwent emergency two-stage surgical procedures in general surgical and coloproctological units in 2011-2017. The group 1 (n=60) included patients who, at the first stage, underwent Hartmann’s procedure, at the second stage – stoma reversal. The group 2 (n=52) included patients with a loop colostomy at the first stage and radical elective surgery as a second stage. The comparative analysis between the groups was carried out according to the following criteria: the type of surgery, the type of intestinal stoma, the rate and type of postoperative complications, postoperative mortality, resection status (R0/R1), the number of removed lymph nodes, the rate of adjuvant polychemotherapy (PChT).

RESULTS: postoperative mortality in the group 1 was 3.33% (n=2) and occurred after the first main stage (Hartmann’s procedure), there were no deaths in group 2 (p=0.28). The procedures in group 2 fully met the criteria of oncological radicalism based on the number of lymph nodes examined and resection status (p<0.0001 and p<0.0001, respectively). Three-year overall survival at stage IIB in group 1 was 44.4% vs 75.2% in group 2 (p<0.0001); with IIIB in the 1st group – 60.3% vs 68.2% in group 2 (p=0.034); at IIIС in the 1st group – 35.7% vs 60.7% in the 2nd group (p=0.009). The 3-year disease – free survival at stage IIB in the 1st group was 41.7% vs 68.8% in the 2nd group (p<0.0001); with IIIB in the 1st group – 53.6% vs 64.5% in group 2 (p=0.036); at IIIС in the 1st group – 33.2% vs 60.8% in the 2nd group (p=0.023).

CONCLUSION: for sigmoid colon cancer complicated by decompensated obstruction, in general hospitals the stage treatment with the colostomy at the first stage is preferable.

Evaluating the Suitability of a Combine Harvester Equipped with the Sunflower Header to Harvest Cardoon Seeds: A Case Study in Central Italy
Authors: Latterini Francesco , Stefanoni Walter , Sebastiano Simone , Baldi Gian Maria , Pari Luigi
Published: December 2020

Cardoon seeds have been proved to thrive in the Mediterranean region, even under low input management and its biomass is suitable for several food and industrial uses. Despite that, a proper value chain has not been set properly and uncertainty still lays among producers and industries, particularly concerning the harvesting stage. The present study supports, via field trials, the hypothesis that cardoon seeds can be harvested using a conventional combine harvester equipped with the sunflower header. Theoretical field capacity (TFC), effective field capacity (EFC), and field efficiency (FE) were 2.36 ha h−1, 2.05 ha h−1, and 1.82 Mg h−1, respectively, while harvesting costs were calculated as 69.52 € ha−1. Seed loss was only 3.2% w/w of the potential seed yield. The machinery’s performance, costs, and seed loss are comparable with sunflower harvesting, underlying the possibility to use the available technology directly to harvest cardoon seeds.
Hydrogen Storage in Propane-Hydrate: Theoretical and Experimental Study
Authors: Ghaani Mohammad Reza , Takeya Satoshi , English Niall J.
Published: December 2020

There have been studies on gas-phase promoter facilitation of H2-containing clathrates. In the present study, non-equilibrium molecular dynamics (NEMD) simulations were conducted to analyse hydrogen release and uptake from/into propane planar clathrate surfaces at 180–273 K. The kinetics of the formation of propane hydrate as the host for hydrogen as well as hydrogen uptake into this framework was investigated experimentally using a fixed-bed reactor. The experimental hydrogen storage capacity propane hydrate was found to be around 1.04 wt% in compare with the theoretical expected 1.13 wt% storage capacity of propane hydrate. As a result, we advocate some limitation of gas-dispersion (fixed-bed) reactors such as the possibility of having un-reacted water as well as limited diffusion of hydrogen in the bulk hydrate.

Background: The purpose of this study is to examine the lower extremity intra-segment coordination and variability of road cyclists during pedaling at different intensities. Methods: Eleven semi-professional road cyclists perform four trials at workloads of 50%, 75%, 100%, and 125% of their maximum power output in a randomized order. Thigh, shank, and foot range of motions (ROM) and the coordination and variability of these segments are compared across different pedaling intensities. Results: Foot ROM in the sagittal plane and shank ROM in the transverse plane are significantly different between different pedaling intensities. Moreover, specific coupling patterns and variabilities are observed across the pedaling cycle; however, they were not significantly different across different pedaling intensities in four pedaling phases. Conclusion: The results highlight the role of knee extensors and plantar flexors during the first and second half of the propulsion phase of pedaling, respectively. Thigh abduction dominancy with faster movement compared to the shank indicates a more valgus stress during the propulsive phase of pedaling, which can increase the risk of overuse injuries in the knee. Moreover, the smaller variability during the transition between the propulsive and recovery phases indicates a reduction in degrees of freedom and may increase the risk of overuse injuries.
MEMS Acoustic Emission Sensors
Authors: Ozevin Didem
Published: December 2020

This paper presents a review of state-of-the-art micro-electro-mechanical-systems (MEMS) acoustic emission (AE) sensors. MEMS AE sensors are designed to detect active defects in materials with the transduction mechanisms of piezoresistivity, capacitance or piezoelectricity. The majority of MEMS AE sensors are designed as resonators to improve the signal-to-noise ratio. The fundamental design variables of MEMS AE sensors include resonant frequency, bandwidth/quality factor and sensitivity. Micromachining methods have the flexibility to tune the sensor frequency to a particular range, which is important, as the frequency of AE signal depends on defect modes, constitutive properties and structural composition. This paper summarizes the properties of MEMS AE sensors, their design specifications and applications for detecting the simulated and real AE sources and discusses the future outlook.

Published: December 2020

This paper presents an experiment using a radio frequency atmospheric pressure plasma jet to generate cold plasma for pre-sowing stimulation of Wolska onion seeds. Impact of the He + N2 afterglow plasma on germination was investigated. Eight groups of seeds characterized by different exposure times (2, 5, 10, 15, 60, 120, 240, and 480 s) and distance from the electrodes (20 mm and 50 mm) were used. Pre-sowing plasma stimulation of the seeds improved the germination capacity and germination energy for all tested groups, relative to control. The impact of radio frequency plasma on the onion seed germination parameters was statistically significant. The highest germination parameters were obtained for seeds stimulated for 240 s at a distance of 50 mm. No significant differences in physical and morphological properties of onion seeds were found.
Artificial Potential Field with Discrete Map Transformation for Feasible Indoor Path Planning
Authors: Azmi Muhammad Zulfaqar , Ito Toshio
Published: December 2020

This work considers the path planning problem of personal mobility vehicle (PMV) for indoor navigation using the Artificial Potential Field (APF) method. The APF method sometimes suffers from an infinite loop problem during the planning phase when the goal is blocked by obstacles with certain characteristics. To address the issue, this study deploys the map augmentation method for replanning. When infinite loop situations occur, the map is transformed and the search for drivable path is initiated. The method successfully generates a feasible trajectory when the map is rotated at a certain angle. The scenario of successful planning is shown in the result.
Inhibition of FGF and TGF-β Pathways in hESCs Identify STOX2 as a Novel SMAD2/4 Cofactor

Published: December 2020

The fibroblast growth factor (FGF) and the transforming growth factor-β (TGF-β) pathways are both involved in the maintenance of human embryonic stem cells (hESCs) and regulate the onset of their differentiation. Their converging functions have suggested that these pathways might share a wide range of overlapping targets. Published studies have focused on the long-term effects (24–48 h) of FGF and TGF-β inhibition in hESCs, identifying direct and indirect target genes. In this study, we focused on the earliest transcriptome changes occurring between 3 and 9 h after FGF and TGF-β inhibition to identify direct target genes only. Our analysis clearly shows that only a handful of target transcripts are common to both pathways. This is surprising in light of the previous literature, and has implications for models of cell signaling in human pluripotent cells. In addition, we identified STOX2 as a novel primary target of the TGF-β signaling pathway. We show that STOX2 might act as a novel SMAD2/4 cofactor. Taken together, our results provide insights into the effect of cell signaling on the transcription profile of human pluripotent cells
