Learners’ Difficulties in Self-evaluation in English Vietnamese Translation Quality Assessment
Authors: Nguyen Tri Minh , Dao Trang Xuan Phuong
Published: October 2020

The field of English translation and interpretation has shown an increasing popularity in Vietnam in the context of globalization. However, translation in the target culture still has a certain number of problems in transferring the equivalence between two languages, which causes some ambiguities and misunderstandings for readers (House, 2015). Hence, translation quality assurance is significant in ensuring the degree of suitability of the texts as a post-translation process (Munday, 2016). This paper aimed to investigate the difficulties of English majors of translation and interpretation in assessing the quality of texts translated from English to Vietnamese during the learning process on an independent basis. The study employed the mixed method with 50 fourth-year students at Nguyen Tat Thanh University via questionnaires. The findings revealed that those majors had to deal with five main groups of troubles including (1) time constraints, (2) non-equivalence between English and Vietnamese, (3) insufficient cultural understandings, (4) inadequate supports from lecturers, and especially (5) the lack of official framework for translation quality assessment. This paper also proposes the fundamental for university curriculum developments from the learners’ perspectives.

Published: October 2020

Metalworking is among the arts that have been considered for its unique features throughout history.  Perhaps one of the most important reasons for using it a lot is its stamina and more durability than other materials.  Another thing to consider about this is technology and the use of metals, which Iran has a valuable background in this regard. Lorestan bronze are a prominent example of this.  One of the most important periods in the use of metals is the Sassanid era, during which the period of art also flourishes.  Sassanid art can be considered an important part of Iran and even the world.  This art period is a bridge between pre-Islamic and post-Islamic periods in Iran.  During the Sassanid Empire in Iran, many silver dishes have been made in Iran, some of which has still been remained.  Many of these containers are made of precious metals to symbolize strength and credibility.  One of the most important drawings used in these containers is the picture of hunting and its role and related topics.  Hunting in the pre-Islamic era was one of the best works and honors of the kings, because one more thing in Sassanid art is the attempt to show the holiness and authority of the kings of this era; which has been shown in the use of designs such as the roundabout of the king's head or magnifying the king's image.  In this paper, by presenting examples of silver Plates that includes the role of hunting of kings, it has been tried to introduce and examine these cases.

Published: October 2020

Over the environment, on the basis of days to flowering and suitability for dual purpose analysis was carried out of 100 genotypes including 75 F1s with 20 parents and 5 checks. Data were collected for grain yield, dry fodder yield, protein content in grain, protein content in fodder, TSS and juiciness. Variations between lines, testers and line × tester was significant for all characters. As both grain and dry fodder yield are important dual-purpose attributes, lines ICSA 202, ICSA 349 and ICSA 357 and ICSA 481 were found to be good general combiners for both grain and dry fodder yield. Two crosses viz., ICSA 29002 × SU 1565 and ICSA 356 × SU 1570 exhibited significant SCA effects in all the four environments whereas hybrids ICSA 552 × SU 1561, ICSA 202 × SU 1570,, ICSA 349 × SU 1561, ICSA 208 × SU 1561, ICSA 474 × SU 1561 and ICSA 357 × SU 1565 showed good SCA effects in normal spacing (E1 and E3) and ICSA 481 × SU 1561 and ICSA 399 × SU 1557 in wider spacing (E2 and E4) for both grain and dry fodder yield. These lines and crosses also expressed positive significant GCA and SCA effects for majority of the remaining fodder quality traits.

Authors: Xiang Zhaobao , Wu Xiaoling , Zhong Xue
Published: October 2020

Ultrasonication assisted extraction (UAE) was employed to extract total flavonoids (TF) from Kaempferia galanga L. (KGL) roots. Single-factor experiments were performed to evaluate the effects of the process parameters (solvent-to-material ratio, ethanol concentration, extraction time, ultrasonic power, and extraction temperature) on the TF yield and the response surface methodology (RSM) was used to optimize the extraction parameters. The optimum conditions to obtain the maximum TF yield were solvent-to-material ratio, 25; ethanol concentration, 62%; extraction time, 27.0 min; extraction temperature, 50℃ and ultrasonic power, 225 W. The yield of TF under these conditions reached 3.22 ± 0.12 mg/g of dry root. The analysis of variance and validation test indicated that the proposed method is useful and reliable. The antioxidant capacities of TF of KGL was determined by DPPH· and ABTS+· methods, which revealed that it has good antioxidant activity in both systems.

Published: October 2020

Сучасні тенденції розвитку теорії і практики формування національних інтересів держави та оцінювання стану їх захищеності показує, що одними із визначальних елементів сучасного безпекового середовища для будь-якої країни є стан розвитку їх воєнної та економічної складової. Міцний зв'язок цих двох складових національної безпеки України дозволяє їх поєднати в єдине поняття – воєнно-економічна безпека країни. Сьогодні, воєнно-економічну безпеку можна розглядати як стан захищеності національного економіки держави від зовнішніх та внутрішніх загроз, за якого воно здатна задовольняти економічні потреби воєнної організації для її будівництва, утримання та подальшого розвитку з метою забезпечення необхідного рівня захисту національних інтересів України в цілому. У статті авторами наведено один із можливих підходів до оцінювання стану воєнно-економічної безпеки держави за наявності невизначеної сукупності вхідних та вихідних параметрів за допомогою використання методу нечітких множин та логіко-лінгвістичного підходу. Застосування такого підходу надасть можливості сформувати загальні оцінки стану воєнно-економічної безпеки держави з метою прийняття відповідних управлінських рішень щодо подальшого її розвитку, а також застосування теорії нечітких множин під час оцінювання дозволить оцінювати чутливість та стабільність прийнятих рішень до можливих змін вхідних даних.

THE CRITIQUE OF MADDISON’S METHOD OF REVISING CHINA’S GDP DATA
Authors: Sun Keren , Fang Hua
Published: October 2020

Economist Angus Maddison is famous for his exploring the revision of economic statistical data, including China’s GDP data since the 1990s. This is a useful work. Maddison has revised China's GDP data from multiple angles, including the revision of China's non-material service sector GDP data. Maddison assumed that the non-material service sector in China has had a zero scientific and technological progress rate since the 1990s, while based on the data from the National Bureau of Statistics of China, the rate of scientific and technological progress in the non-material service sector should be big. Maddison's assumptions have led to a significant reduction in China's GDP data, and thus China's economic growth rate has dropped significantly. This paper argues that the high-tech progress rate of the non-material service sector-led and promoted by information technology is not only possible but also very likely, so China’s GDP data is credible in general, and of course, some small deviations and inaccuracies existed in China statistical GDP is understandable and acceptable.

Published: October 2020

Well-respected experts of higher education, including those at the National Survey of Student Engagement (NSSE) and founding director Dr. Alexander Astin of the Higher Education Research Institute at UCLA, have demonstrated strong correlations between the amount of time and effort students put into “educationally purposeful activities” outside the classroom (e.g., student organizations) and positive outcomes of student success, such as satisfaction, persistence, and academic achievement (Astin, 1984, 1993, 1999; Berger and Milem,1993; Pascarella and Terenzini, 2005). This study evaluates student involvement in on-campus student organizations. What characteristics are most highly correlated with participation? Based on the results of previous studies, we hypothesized that student engagement in on-campus student organizations is positively correlated with proximity to campus and that the closer a student lives to campus, the more apt they are to be involved with on-campus student organizations. Not only will students living closer to campus be more active with on-campus student organizations, but they are also more likely to be involved with on-campus student organizations directly related to their major. We also hypothesized that female students are more apt to be involved in on-campus student organizations related to their major than males. Original survey results and future research ideas are discussed.
NEO-REALİST TEORİ IŞIĞINDA FRANSA’NIN BÜYÜK GÜÇ OLARAK YENİDEN DEĞERLENDİRİLMESİ
Authors: KARPUZCU Tevfik
Published: October 2020

Güç kavramı birçok farklı düşünür, yazar ve akademisyen tarafından farklı şekilde ele alınan, üzerinde genel bir uzlaşının söz konusu olmadığı bir kavramdır. Bu kavram üzerinde uzlaşılamaması, alt kavramlar üzerinde de tartışmaları beraberinde getirmiştir. Bu makalede söz konusu tartışmalar üzerine çok fazla yoğunlaşmadan, seçilmiş tanımlamalar üzerinden Fransa’nın büyük güç olarak yeniden değerlendirilmesi esas alınmıştır. Bu çalışmada farklı teorik yaklaşımlar içinden neo-realist yaklaşımın güç kavramını ele alış biçimi teorik çerçeve olarak belirlenmiştir. Neo-realistlerin uluslararası sisteme yaptıkları vurgu ve bu nazarda devletlerin gücünü değerlendirmeleri; bu teorik çerçevenin kullanılmasını önemli hale getirmiştir. Neo-realizmin uluslararası sisteme yaptığı bu vurgu, bir ülkenin gücünü anlamanın en iyi yolunun sistemdeki diğer devletle karşılaştırma ile mümkün olduğu gerçeğini ortaya koymaktadır. Bu nedenle, Fransa’nın güç değerlendirmesi yapılırken karşılaştırmalı bir yöntem izlenmiştir. Güç analizi yapılırken askeri, ekonomik ve teknolojik boyutlar ele alınmış ve Global Firepower indeksinden faydalanılmıştır. Bu üç boyut ele alınırken, neo-realist çerçeve ve 21. yüzyıl gerçekleri göz önüne alınmıştır.

Ülkelerin ekonomilerindeki büyümenin kamu harcamalarını arttırdığına ilişkin görüşlerin yanı sıra bunun tam tersini yani kamu harcamalarındaki artışın ülke ekonomisini büyüttüğünü ileri süren çalışmalar da iktisat yazınında önemli bir yer tutmaktadır. Karşıt görüşlerin varlığı, ekonomik büyüme ile kamu harcama tutarı arasındaki nedenselliğin incelenmesini gerektirmektedir. Buradan hareketle mevcut çalışma 1999-2017 yılları arasında kamu harcamaları ile ekonomik büyüme arasındaki nedensellik ilişkisinin araştırılması amacıyla gerçekleştirilmiştir. Araştırma kapsamında önceki çalışmalar özetlenmiş, veriler toplanmış ve elde edilen verilerle ADF testi, Johansen Eşbütünleşme Testi ve Granger Nedensellik Testi gerçekleştirilmiştir. Analiz sonuçları değerlendirildiğinde bulguların konu ile ilgili önceki çalışmalarla benzer özellikler taşıdığı görülmüş ve ülkemiz ekonomisi için Wagner modeli geçerli yatırım harcamaları için de Keynes modelinin geçerlilik taşıdığı anlaşılmıştır.

Published: October 2020

Mixed marriage causes a legal impact on Indonesian citizens marrying foreign citizens. They cannot have land rights since it is a part of joint property in marriage based on laws and regulations on land in Indonesia following the nationalism principles. The problem involved the guarantee of constitutional rights in land rights ownership is for the Indonesian citizens having a mixed marriage and the requirements for property/assets division agreement in a mixed marriage. This used normative legal research using the legislative approach and case approach. The legal materials consisted of primary legal materials, secondary legal materials, and tertiary legal materials that were then analyzed and concluded using the descriptive-qualitative method. The result was that the Indonesian citizens, having a mixed marriage with foreign citizens, had similar constitutional rights to other Indonesian citizens for land rights provided that the land was not included in joint property and proven by a marriage contract containing property/assets division. The marital property division agreement can be made at the time of or before the wedding, or during the marriage in the form of a Notarial Deed, and be legalized by a marriage registrar. For Moslems, it is registered in the Office of Religious Affairs, while for non-Moslems, it is registered in the Civil Registration Office. If the contract has been legalized, the content in the contract will bind the people who make it (husband and wife).

A Note on the Time to Failure of a Two-Unit Parallel Redundant System with Deterioration on a Lattice
Authors: Dohi Tadashi , Zheng Junjun , Okamura Hiroyuki
Published: October 2020

In this paper, we consider a two-unit parallel redundant system with deterioration on a lattice, where each unit has multi-stage deterioration levels, say, n levels. The transition from one deterioration level to the subsequent level occurs following the well-known Marshall-Olkin bivariate exponential distribution. We derive the closed form of the Laplace transform of the time to system failure in the two-unit parallel redundant system with deterioration on n×n lattice without repair and simultaneous failure, as well as the simple system on 3×3 lattice.
Survivability and Vulnerability Analysis of Cloud RAID Systems under Disk Faults and Attacks
Authors: Liu Qisi , Xing Liudong
Published: October 2020

In this paper we model and analyze survivability and vulnerability of a cloud RAID (Redundant Array of Independent Disks) storage system subject to disk faults and cyber-attacks. The cloud RAID survivability is concerned with the system’s ability to function correctly even under the circumstance of hazardous behaviors including disk failures and malicious attacks. The cloud RAID invulnerability is concerned with the system’s ability to function correctly while occupying some state immune to malicious attacks. A continuous-time Markov chains-based method is suggested to perform the disk level survivability and invulnerability analysis. Combinatorial methods are then presented for the cloud RAID system level analysis, which can accommodate both homogeneous (based on binomial coefficients) and heterogeneous (based on multi-valued decision diagrams) disks. A detailed case study on a cloud RAID 5 system is conducted to illustrate the application of the proposed methods. Impacts of different parameters on the disk and system survivability and invulnerability are also investigated through numerical analysis.

Published: October 2020

In this study, we calculate hesitant and dual hesitant fuzzy reliability of linear and circular consecutive 2-out-of-4:G system from reliability function and Weibull distribution. After that, we introduced some basic methods for investigating the fuzzy reliability in the form of upper and lower membership and non- membership function having an aggregation operator with equal weights. At last, two numerical examples are also illustrated with the considered technique.

Today, so as to meet the user's requirement, modification of software is necessarily required. But at the same time, to incorporate these modifications and requirements there are enormous changes which are made to the coding of the software and over a period of time these changes make the software complex. Largely there are three types of code changes occur in the source code namely, bug repair, feature enhancement & addition of new features, but these changes bring the uncertainty in the bug removal rate. In this paper, these uncertainties have been explicitly modeled and using three-dimensional wiener processes that define the three types of fluctuation; we have come up with an entropy prediction modeling framework with a unified approach. The analytical solution of the equation is interpreted using Itô’s process. The models are fitted on three real life projects namely Avro, Hive and Pig of Apache open source software (OSS) The experimental findings show that present models exhibit accurate estimation results and have strong prediction skills.

Thirty clinically healthy Holstein-Friesian cows underwent twice daily machine milking and ultrasonographic examinations of the udder just prior to and after milking. Digital ultrasonographic images of each udder quarter were subjected to computer-assisted echotextural analyses to obtain mean numerical pixel values (NPVs) and pixel heterogeneity (PSD) of the mammary gland parenchyma. The average milk yield and pH were higher (p < 0.05) in the morning, whereas crude fat, total solids, solids non-fat and citric acid content were higher (p < 0.05) during the evening milking period. Mean NPVs and PSDs of the mammary gland parenchyma were greater (p < 0.05) after than before milking. There were significant correlations among echotextural characteristics of the udder and protein percentage, lactose content and freezing point depression determined in the milk samples collected in the morning and crude protein, casein, lactose and solids non-fat in the evening. Our results can be interpreted to suggest that computerized analysis of the mammary gland ultrasonograms has the makings of a technique for estimating non-fat milk constituents in cows. However, future validating studies are necessary before this method can be employed in commercial settings and research. Moreover, significant inter-quarter differences in udder echogenicity may necessitate further echotextural studies of separate quarters.

ZnO is utilized as a promising material for various electronic and energy areas due to its outstanding chemical stability, abundance, non-toxicity, and low cost. However, controlling electronic transport properties of ZnO by facile strategy is still necessary for wider applications. Here, we synthesized reduced graphene oxide incorporated Al-doped ZnO nanocomposite thin film prepared by the electrospray deposition method and investigated the electronic transport behavior. The electron transport in pristine Al-doped ZnO thin film is strongly affected by grain boundary scattering, but significant enhancement of carrier mobility is observed in reduced graphene oxide-incorporated Al-doped ZnO nanocomposite thin film. The results demonstrate that this hybrid strategy with graphene has an important effect on the charge transport behavior in ZnO polycrystalline materials.
How Occupational Mercury Neurotoxicity Is Affected by Genetic Factors. A Systematic Review
Authors: Chirico Francesco , Scoditti Egeria , Viora Carlo , Magnavita Nicola
Published: October 2020

Occupational exposure to elemental mercury still represents a significant risk in the workplace. The sensitivity of the exposed subjects varies considerably. This study aims to summarize the literature on the role of genetic factors in occupationally exposed cohorts. A systematic search of the literature was carried out on PubMed Central (PMC), MEDLINE, and Google Scholar databases in accordance with the “Preferred Reporting Items for Systematic reviews and Meta-Analyses” (PRISMA) guidelines, from 1946 to July 2020. Ten cross-sectional studies were included in the review. All studies referred to the polymorphisms that can favour some neurotoxic effects of the metal in occupational cohorts. Some genetic variants may be associated with an increase in the occupational effects of mercury. Given the limited evidence, genetic screening of all mercury-exposed workers is not recommended. However, a personalized search for polymorphisms could be taken into consideration if exposed workers report early neurotoxic symptoms.

The small-molecule E26 transformation-specific (ETS) factor inhibitor YK-4-279 was developed for therapy of ETS/EWS fusion-driven Ewing’s sarcoma. Here we aimed to identify molecular factors underlying YK-4-279 responsiveness in ETS fusion-negative cancers. Cell viability screenings that deletion of P53 induced hypersensitization against YK-4-279 especially in the BRAFV600E-mutated colon cancer model RKO. This effect was comparably minor in the BRAF wild-type HCT116 colon cancer model. Out of all ETS transcription factor family members, especially ETS1 overexpression at mRNA and protein level was induced by deletion of P53 specifically under BRAF-mutated conditions. Exposure to YK-4-279 reverted ETS1 upregulation induced by P53 knock-out in RKO cells. Despite upregulation of p53 by YK-4-279 itself in RKOp53 wild-type cells, YK-4-279-mediated hyperphosphorylation of histone histone H2A.x was distinctly more pronounced in the P53 knock-out background. YK-4-279-induced cell death in RKOp53-knock-out cells involved hyperPARylation of PARP1, translocation of the apoptosis-inducible factor AIF into nuclei, and induction of mitochondrial membrane depolarization, all hallmarks of parthanatos. Accordingly, pharmacological PARP as well as BRAFV600E inhibition showed antagonistic activity with YK-4-279 especially in the P53 knock-out background. Taken together, we identified ETS factor inhibition as a promising strategy for the treatment of notoriously therapy-resistant p53-null solid tumours with activating MAPK mutations.
Modelling Excess Mortality in Covid-19-Like Epidemics
Authors: Burda Zdzislaw
Published: October 2020

We develop an agent-based model to assess the cumulative number of deaths during hypothetical Covid-19-like epidemics for various non-pharmaceutical intervention strategies. The model simulates three interrelated stochastic processes: epidemic spreading, availability of respiratory ventilators and changes in death statistics. We consider local and non-local modes of disease transmission. The first simulates transmission through social contacts in the vicinity of the place of residence while the second through social contacts in public places: schools, hospitals, airports, etc., where many people meet, who live in remote geographic locations. Epidemic spreading is modelled as a discrete-time stochastic process on random geometric networks. We use the Monte–Carlo method in the simulations. The following assumptions are made. The basic reproduction number is R0=2.5 and the infectious period lasts approximately ten days. Infections lead to severe acute respiratory syndrome in about one percent of cases, which are likely to lead to respiratory default and death, unless the patient receives an appropriate medical treatment. The healthcare system capacity is simulated by the availability of respiratory ventilators or intensive care beds. Some parameters of the model, like mortality rates or the number of respiratory ventilators per 100,000 inhabitants, are chosen to simulate the real values for the USA and Poland. In the simulations we compare ‘do-nothing’ strategy with mitigation strategies based on social distancing and reducing social mixing. We study epidemics in the pre-vacine era, where immunity is obtained only by infection. The model applies only to epidemics for which reinfections are rare and can be neglected. The results of the simulations show that strategies that slow the development of an epidemic too much in the early stages do not significantly reduce the overall number of deaths in the long term, but increase the duration of the epidemic. In particular, a hybrid strategy where lockdown is held for some time and is then completely released, is inefficient.
