Published: June 2021

Unemployment is a serious problem for all over the world. It is a crucial task to endeavor with the unemployment for the welfare of the world. Once, the potential factors should be known to accomplish this task. The aim of this study is to investigate the determinants of the unemployment rates using fractional regression models for the 35 OECD (Organization for Economic Co-operation and Development) countries over the periods 2000-2017. We determined the factor affecting the unemployment rate by the fractional regression model using GMMbgw and GMMpre estimators for panel data. The empirical results revealed the significant determinants of unemployment as the result of the fractional regression models. Finally, we observe that saving rates, the growth rate of import and export are expressive on the unemployment rates

A polyphenolic extract of Robinia pseudoacacia L. flowers was prepared using a hydro-ethanolic extraction phase. The chemical analysis of the extract consisted in the assessment of the total polyphenolic content (Folin-Ciocalteu method) and the flavonoid fingerprint of the extract determined by high-performance thin-layer chromatography (HPTLC). Two methods ferric reducing antioxidant power (FRAP) and radical scavenging activity with DPPH were used to measure the antioxidant activity of the extract. The cytotoxic and antitumor effects were evaluated on two cell lines: palatal mesenchymal stem cells (pMSCs) and epithelial cells derived from human cervical adenocarcinoma (HeLa (ATTC® CCL-2™)). The chemical content of Robinia pseudoacacia L. flowers extract reveals the presence of apigenin-7-glucoside and rutin. Results indicated high antioxidant activity with both methods (FRAP and DPPH). No cytotoxic effects of the extract were observed on the pMSCs cell line. The extract induced significant necrosis and apoptosis of the HeLa cells, proving an antitumor effect in vitro. The data confirm the antioxidant and antitumor effects of the polyphenols and the therapeutic potential of Robinia pseudoacaia flowers extract. In the last years, the therapeutic effect of the compounds from Robinia pseudoacacia flowers is less discussed; even the traditional medicine mentions them as helpful medicinal means. The present paper points out the correlation between Robinia pseudoacacia flowers polyphenolic compounds and their chemical and biological effects.
ALGUMAS INCURSÕES ENTRE O HISTÓRICO E O MARAVILHOSO EM A LÁGRIMA DE UM CAETÉ
Authors: Maciel Luciana , Silva Tatiana
Published: June 2021

In this article, we intend to understand certain literary and historical elements that permeate the work A Lágrima de Um Caeté (1849), by Nísia Floresta, and, for this purpose, we will dialogue with Candido (1985), Margutti (2019), Vasconcelos and Ramalho (2007), Duarte (1999) and Quijano (2005). Our main objective is to follow some paths that show how the book has both traces of a critical Indianism and elements that go back to epic texts for recovering the collective heroism, the historical and the wonderful plan, but at no time will we put the author's narrative lyricism in a prefixed and/or crystallized pattern, as this does not match the directions of the text that we will look at. Furthermore, we will also touch on the issue of decoloniality, as we will enter an environment of acculturation and destruction of indigenous culture and the text under study ends up becoming a poetry of resistance.
ÇUVAŞ KÜLTÜRÜNDE ANT İÇME
Authors: YAVUZ Cemalettin
Published: June 2021

Bu makalede Çuvaş kültüründe karşılaştığımız ant içme olgusu kavramsal, işlevsel, performatif ve anlamsal boyutlarıyla incelenmiştir. Makale iki ana bölüm meydana getirecek şekilde kurgulanmıştır. Birinci kısımda evrensel bir kültürel olgu olarak kabul edilen ant içmenin temel yapısal ilkeleri belirlenmiştir. Bu ilkeler; bir beyanda bulunma, bir veya birden fazla insanüstü otoritenin/garantörün gücüne ya da şahitliğine başvurma ve son olarak teminat ya da yaptırım işlevi gören şartlı öz kargışta bulunma şeklinde sıralanabilir. İnsanlığın ve kültürlerin evrensel özellikleri olarak görülen bu yapısal ilkeler temelinde Türk kültüründe ant içme geleneğiyle ilgili günümüze kadar yapılmış olan çalışmalardaki kavramlaştırma ve tasnif problemleri tespit edilmiştir. İkinci kısımda ise söz konusu yapısal ilkelerin, Çuvaş kültürünün kendine özgü özellikleriyle birleşmesi sonucu ortaya çıkan görünüşleri incelenmiştir. Bu görünüşler, her kültürü kendine özgü kılan dinamiklerin bir sonucu olarak kabul edilmiştir. Çevresel, sosyal, ekonomik ve tarihî etkenlerle şekillenen bu kültürel özelliklerin genetik boyutu göz ardı edilmemiş, Çuvaşlardaki ant içme biçimleri diğer Türk topluluklarındaki benzerleriyle de karşılaştırılmıştır. Verilerin elde edildiği dönemde Çuvaşların tarım ve hayvancılıkla geçinen, yerleşik, parçalı ve kapalı gruplardan meydana gelen bir topluluk olması ant içme biçimlerini de şekillendirmiştir. Bu nedenle Çuvaş antlarının büyük oranda anlaşmazlıkların giderilmesine dönük olduğu; toprağın, atalar kültünün ve doğal fenomenlerin en önemli otorite kaynakları olarak belirdiği görülmüştür.
Nesh İle İlgili Rivayetlerde Söz Konusu Edilen Ayetler/Sureler Meselesi
Authors: YOLCU Mehmet , AKBOĞA Mikail
Published: June 2021

Kur’ân-ı Kerîm’in Yüce Allah tarafından indirildiği ve Onun tarafından muhafaza edileceğine ilişkin beyanlar hem sübutu hem de delaleti açısından katidir (Hicr 9). Yani Yüce Kur’ân onu gönderen Allah tarafından korunmaktadır. Bu konuda ulema arasında herhangi bir ihtilaf olmamakla beraber Hadis Kaynaklarında, Ulûmu’l-Kur’an ve Tefsirlerde birçok rivayette bazı surelerin daha önce uzun iken kısaldıkları, kimi ayetlerin ise tamamen unutuldukları kaydedilmektedir. Bu tür rivayetlerin benzerleri farklı kaynaklarda geçtiğinde tenkide tabi tutulurken “bizim” diye kabul edilen eserlerde yer alınca makul ve mutedil kıstaslarla süzgeçten geçirilmedikleri müşahede edilmektedir. Bu araştırmada bu tür rivayetlerin, nerede geçtiğinden sarfı nazar edilerek, mutlak manada kritiği yapılmaktadır. Bu rivayetlerin nerelerde yer aldıkları, hangi konularda yoğunlaştıkları, Kur’ân’ın korunmuş olduğu gerçeği birlikte ele alınarak aralarında ne tür çelişkiler, uyuşmazlıklar olduğu nazara verilmektedir.

A Error Analysis Performed on English 230 Students’ Elpt Compositions: A Basis for A Proposed Intensive Grammar Enrichment
Authors: Masorong Sharifa Khalid
Published: June 2021

The language of the humankind is linked to the creation of meaning and expressions of human behaviors and emotions. Language is said to manipulate and persuade people’s perception of ‘reality’ (Holmes, 2013). The reality—social and linguistic landscapes— that people construct is affected by the linguistic choices members of the community make. 

This research investigated the possibility of a Meranaw uniform orthography in terms of the word spelling and symbols by examining the varieties of the language in terms of its lexicons.  Understanding varieties can unlock answers questions regarding variety’s causes and its contribution to the development of the language in terms of orthography—which can actually help Meranaw writers extend studies on other components of the language. These factors contributed to the direction of this paper as it attempted to investigate the sprouting of the varieties and its lexical changes. The findings of the study revealed that even though there were Meranaw lexical variants, it does not hinder the communication to be effective. The paper also showed that Meranaw lexical variants are mutually intelligible among the surveyed Meranaw communities. Mutual intelligibility suggests that language is convention--- meaning that even if there are varieties, the Meranaw language itself serve as a unifying link in keeping a society intact. The Meranaw language brings together one culture and its usage is a means to express community’s style in an effort to create a social reality. This reality allows them to express their thoughts and ideas through their language

Auditors’ Duty To Detect Related Party Transactions, To Be Professionally Skeptical, and To Detect Fraud: A Case Study of Aegean Marine Petroleum Network, Inc.
Authors:   Associate Professor of Accounting and Business Law, College of Business, Tarleton State University, Fort Worth, Texas USA, Blythe Stephen Errol
Published: June 2021

This is a case study of Aegean Marine Petroleum Network, Inc. (Aegean). Aegean’s founder and former CEO was the mastermind of several fraud schemes which pilfered $300 million from the company. During 2006-2018, Aegean’s Big 4 auditors, Deloitte and Price Waterhouse, failed to detect the fraud and issued clean, unqualified opinions year after year. After the fraud was discovered by Aegean’s audit committee in 2018, a group of Aegean’s stockholders filed a securities fraud lawsuit in New York City against the former CEO and the two auditors, and it will come to trial in the near future. U.S. Public Company Accounting Oversight Board (PCAOB) standards require an auditor to be professionally skeptical during an audit. He must maintain a questioning mind and make a critical objective assessment of audit evidence. In the Aegean case, the court held if the auditors had been more professionally skeptical, they may have been able to discover the massive fraud. PCAOB standards also require an auditor to search for related party transactions and to disclose them. In the Aegean case, the court noted it is inexcusable that the auditors were not aware that the former CEO owned Oil Tank, Inc., a firm which siphoned off millions of dollars from Aegean during the oil storage facility construction project. If they had been aware of this relationship, they might have been able to uncover the massive fraud. PCAOB standards also require an auditor to search for fraud. In the Aegean case, the former CEO engaged in several fraud schemes, yet the auditors were ignorant of them and issued unqualified audit opinions. This led the court to conclude that the auditors exhibited “willful blindness.”

Authors: Saputra Dani Nur
Published: June 2021

One of the competencies that must be possessed in the 21st century is digital literacy skills. This ability must be possessed by every student and lecturer in integrating digital platforms into learning, especially in the current pandemic era. This study aims to investigate the effectiveness of a digital platform in its application to practical courses. Researchers use google classroom as a sample of the many types of digital platforms. This type of research is descriptive qualitative using a case study approach. The object of this research were 26 active students who took music ensemble courses, while the variable being investigated was the use of google classroom in learning. Data collection was carried out by means of questionnaires, observations, and interviews. The results show that digital platforms can be used as an alternative solution to carry out online learning in the midst of a pandemic. However, it is not optimal for the music ensemble course because of several factors, including the location of the student's residence which is difficult to get a signal, material that students find difficult, the availability of their own musical instruments, and the student's ability to play music.

Zanthoxylum alatum (Z. alatum), an important medicinal plant is used for various ailments including chest infection, cough, cholera, fever, stomach disorders, gas problems, indigestion, piles, toothache, gum problems, dyspepsia and stomachic worldwide. Keeping in view the medicinal potential of this plant, fruit and leaves methanolic (MeOH) extracts were prepared, evaluated for antioxidant activity by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and for antibacterial potential by well diffusion and macrodilution methods in-vitro. Our results confirmed that Z. alatum fruit and leaves extracts have significant antioxidant activity with IC50 values 0.28 ± 0.07 mg/ml and 0.34 ± 0.05 mg/ml, respectively. The inhibitory trend at highest tested concentration (120 mg/ml) at 24 hr incubation in well diffusion method was recorded as 0.39, 0.30, 0.28, 0.27 and 0.18 cm against S. pyogenes, B. cereus, E. coli, S. aureus and S. enterica for leaf extract, respectively. In case of fruit extract inhibitory trend at highest tested concentration was observed as 0.33, 0.32, 0.31, 0.30 and 0.28 cm against S. aureus, S. enterica, S. pyogenes, B. cereus and E. coli, respectively. The fruit extract showed higher zones of inhibition than leaves extracts against all the test bacteria except S. pyogenes. Moreover, highest zones of inhibition were observed at lowest incubation (24 hr) and lowest zones were observed at highest incubation period (72 hr) for all tested concentrations. Macrodilution method showed antibacterial susceptibility in liquid medium with different levels of IC50 values ranging from 1.6±0.13 mg/ml to 10.3±0.7 5mg/ml. Interestingly, none of the tested bacteria showed resistance against any of the test extract in well diffusion or macrodilution method expressing the Z. alatum as potent candidates to kill bacteria in semisolid or in liquid medium to fulfill medical needs in future.

İşbirliğine dayalı tasarım projeleri kapsamındaki uygulama ve yürütme modellerine dayanan bilgilerle konunun ele alındığı bu çalışmanın farklı açılardan yaklaşımlarla daha sonra yapılacak çalışmalara öncü olması, katkı sağlaması beklenmektedir.
Audio cross-fade implementation via rational functions
Authors: Lupsa-Tataru Lucian
Published: June 2021

Implementation of the cross-fade audio effect requires shaping the fade profile for a certain audio content that is to be faded out, as well as customizing the audio fade for an additional audio content, which is to be faded in, with the purpose of achieving a smooth transition between the two different audio contents. Similar to the case of applying adjustable fades, the audio cross-fades are usually carried out in the off-line mode, by employing various transcendental functions to shape the audio fades (both fade-out and fade-in effects). To improve the computational capabilities by minimizing the delay between receiving the position within the cross-fade effect and returning both the volume of the faded out section and the volume of the faded in one, we consider that, during the cross-fade effect, the audio volume of each of the two overlapping sections is the output of a rational function i.e. a mapping defined by a rational fraction. A plain HTML5/JavaScript implementation, prepared to be tested in any major browser, is advanced in the paper in order to highlight the suitability of the suggested approach to audio cross-fade customization with real-time computing.

Hasil penelitian menunjukkan bahwa penerapan kebijakan mitigasi fisik dan nonfisik sebagai upaya penanggulangan bencana belum maksimal dilakukan untuk menurunkan kerentanan dan mengurangi resiko bencana di Kabupaten Bima, hal tersebut terjadi karena lemahnya kapasitas Pemerintah Daerah dan masyarakat terutama dalam berinovasi dan membangun budaya keselamatan. Pemerintah Daerah juga belum maksimal dalam menyiapkan program dan aksi yang tepat terhadap beberapa bencana prioritas/ bencana tingkat bahaya tinggi. Selain itu indeks ketahanan bencana Kabupaten Bima berada pada level 3, menunjukkan bahwa Pemerintah Daerah Kabupaten Bima telah melaksanakan beberapa tindakan mitigasi sebagai upaya mengurangi risiko bencana namun dengan pencapaian-pencapaian yang masih bersifat sporadis sehingga belum menunjukkan kapasitas yang baik dalam menghadapi potensi bencana yang sewaktu-waktu dapat terjadi.

AbstractThis study aimed to compare consumption behavior before and during the pandemic, also to analyze the health and sharia aspects of food or products consumed. This paper is based on the population in the study with a sample of 100 people, using judgment sampling with the Slovin formula. Data were collected by distributing online questionnaire. This type of research is cross sectional study using descriptive quantitative analysis method. The results showed that the people's consumption behavior before and during the pandemic experienced changes by looking at the 13 indicators in the questionnaire with an average change of over 50 percent. This changing condition is believed to have occurred due to one of the impacts of the government's recommendation to avoid crowds by implementing the PSBB policy. Correspondingly, the change in consumption behavior during a pandemic, as found in this study, lies in the uncertainty of the country's economic situation due to the pandemic. This paper suggests the need to expand the scope of the research area and add data sources to allow understanding of the impact of a pandemic on changes in people's consumption behavior in a deep and comprehensive manner.AbstrakPenelitian ini bertujuan untuk membandingkan perilaku konsumsi sebelum dan selama pandemi serta menganalisis aspek kesehatan dan kesyariahan dari makanan atau produk yang dikonsumsi.  Tulisan ini didasarkan pada populasi dalam penelitian dengan sampel 100 orang, menggunakan jenis sampel judgment sampling dengan menggunakan rumus slovin. Data dikumpulkan dengan penyebaran kuesioner secara online. Jenis penelitian cross sectional study menggunakan metode analisis kuantitatif deskriptif. Hasil penelitian menunjukkan bahwa perilaku konsumsi masyarakat sebelum dan selama pandemi mengalami perubahan dengan melihat dari 13 indikator yang ada dalam kuesioner dengan rata-rata perubahan mengalami peningkatan di atas 50 persen. Kondisi perubahan tersebut diyakini terjadi karena salah satu dampak adanya anjuran pemerintah untuk menghindari kerumunan dengan menerapkan kebijakan PSBB. Sejalan dengan itu, perubahan perilaku konsumsi selama pandemi, sebagaimana ditemukan pada studi ini, terletak pada ketidakpastian situasi ekonomi negara akibat pandemi. Tulisan ini menyarankan perlunya perluasan cakupan wilayah penelitian dan penambahan sumber data untuk memungkinkan dipahaminya dampak pandemi pada perubahan perilaku konsumsi masyarakat secara mendalam dan komprehensif.

A new method based on LC-ICP-MS technique has been developed and validated for the simultaneous determination of borax and polyphosphates (phosphate, pyrophosphate, tripolyphosphate) in foods. The analytes were extracted from the samples with 18 mM sulfuric acid solution using ultrasonic vibration extraction technique before being filtered and analyzed by LC-ICP-MS system. The method was validated with calibration curves that have the coefficient of determination (R2) higher than 0.995. The method limits of detection (LOD) of borax, phosphate, pyrophosphate (Pyro-P), and tripolyphosphate (Tripoly-P) were in the range of 2.5 to 15.0 mg/kg. The recoveries were in the range of 86.0 to 107.0% and the relative standard deviations were below 5.23%. A total of 83 samples of cereal, meat, and seafood-based food were analyzed for research purposes. The results did not indicate a risk of using borax and polyphosphates in most rice products. Meanwhile, meat products including pork paste and roasted pork sold in traditional markets had a borax detection rate of over 60%. This study showed that there was still a risk of using borax in food processing and the use of polyphosphates in food products collected in some districts in Hanoi city.

A method using solid phase extraction (SPE) and high performance liquid chromatography with diode array detector (HPLC-DAD) has been optimized for the simultaneous determination of notoginsenoside R1 and three ginsenosides Rg1, Re, Rb1 in solid, oil, and liquid dietary supplements. The substances were separated by an InertSustain C18 column (250 mm × 4.6 mm i.d.; particle size 5 μm) with a gradient program composed of acetonitrile and water. Linearities were in the range of 4.0 - 400 μg/mL with the coefficients of determination were more than 0.999. The limits of detection and limits of quantitation were 2.13 - 6.89 μg/g and 7.11 - 22.98 μg/g, respectively. The recovery values of the compounds were in the range of 87.2 - 103.5%. The precision study showed the intra-day relative standard deviation (RSD) of 1.41 - 2.91%, and inter-day RSD of 1.87 - 4.85%, which meet the AOAC International requirements. The method was applied to determine the content of notoginsenoside R1, ginsenoside Rg1, ginsenoside Re, and ginsenoside Rb1 in 20 dietary supplement samples containing Ginseng and Pseudoginseng.

Authors: KARANFİLOĞLU Mehmet , SAĞLAM Murat
Published: June 2021

Health communication, which is as essential as health, needs to be re-examined in developing and changing circumstances. In the pandemic, the health sector was intensely affected, as in all areas. In this process, the need for communication technologies has increased. Some that are already being digitalized have gained momentum and have been subjected to digital transformation. Following this, we are in a period where health care professionals and patients are using these technologies intensively. With the pandemic, old habits have changed, and new ones that are important for digital skills have been replaced. Many digital things have been included in our lives, such as video conferences, events starting with “distance” Therefore, to understand the new communication opportunities in health, these developments in digitalization and health have required detailed analysis. With this study, in-depth information was tried to be obtained by conducting qualitative research about health care professionals and their use of communication technologies. As a result of the analysis, four themes related to technology usage reasons and the perception of health care employees were obtained. Accordingly, the use of communication technologies in health communication has increased. Health care professionals and their patients use phones and tablets to accomplish their communicative activities and benefit from various aspects.
Efecto del ejercicio físico sobre la inflamación en adultos mayores hospitalizados en unidad de agudos
Authors:   , Recarey Rodríguez Anel Eduardo
Published: June 2021

El envejecimiento se asocia con un deterioro del sistema inmunológico, un estado inflamatoriocrónico de bajo grado y una serie de alteraciones metabólicas que desencadenan enfermedades como la sarcopenia, conduciendo progresivamente al deterioro de la capacidad funcional que impacta negativamente en la calidad de vida y el bienestar emocional. Dichas alteraciones se asocian, a su vez, con el incremento de enfermedades crónicas, riesgo de hospitalización, costos de la atención sanitaria, morbilidad y muerte para esta vulnerable población. En este sentido, se ha sugerido que el ejercicio físico supervisado puede contrarrestar los efectos negativos delenvejecimiento al reducir la inflamación y las alteraciones metabólicas, provocando así unproceso de envejecimiento saludable y mejorando la calidad de vida de estos pacientes. Sin embargo, no está claro qué efecto tienen las intervenciones con ejercicios sobre dichas variables en pacientes muy ancianos durante la hospitalización aguda. En esta Tesis Doctoral, presentamos los resultados de dos estudios: una revisión sistemática y un estudio clínico que examina el impacto de las intervenciones con programas de ejercicio físico multicomponente en la mejora den los resultados metabólicos e inflamatorios, previniendo así el deterioro funcional y mejorando el estado cognitivo y la calidad de vida en pacientes adultos mayores durante la hospitalización aguda, en reconocidas revistas científicas internacionales indexadas JCR reconocidas en la Web of Science - Journal Citation Reports.
Automatic Thai Finger Spelling Transcription
Authors: NAKJAI Pisit , KATANYUKUL Tatpong
Published: June 2021

This article explores a transcription of a video recording Thai Finger Spelling (TFS)—a specific signing mode used in Thai sign language—to a corresponding Thai word. TFS copes with 42 Thai alphabets and 20 vowels using multiple and complex schemes. This leads to many technical challenges uncommon in spelling schemes of other sign languages. Our proposed system, Automatic Thai Finger Spelling Transcription (ATFS), processes a signing video in 3 stages: ALS marking video frames to easily remove any non-signing frame as well as conveniently group frames associating to the same alphabet, SR classifying a signing image frame to a sign label (or its equivalence), and SSR transcribing a series of signs into alphabets. ALS utilizes the TFS practice of signing different alphabets at different locations. SR and SSC employ well-adopted spatial and sequential models. Our ATFS has been found to achieve Alphabet Error Rate (AER) 0.256 (c.f. 0.63 of the baseline method). In addition to ATFS, our findings have disclosed a benefit of coupling image classification and sequence modeling stages by using a feature or penultimate vector for label representation rather than a definitive label or one-hot coding. Our results also assert the necessity of a smoothening mechanism in ALS and reveal a benefit of our proposed WFS, which could lead to over 15.88 % improvement. For TFS transcription, our work emphasizes the utilization of signing location in the identification of different alphabets. This is contrary to a common belief of exploiting signing time duration, which are shown to be ineffective by our data.
