Published: July 2021

In this study, it was aimed to investigate the presence of Klebsiella pneumoniae and phenotypically carbapenemase, extended-spectrum β-lactamase (ESBL), acquired-AmpC beta-lactamase, and multiple antibiotic resistance of the isolates in the faeces of budgerigars and parrots. A total of 96 faecal samples belonging to 54 budgerigars and 42 parrots were used in the study. Cultivation was performed on various media for the identification of Klebsiella pneuomiae from the collected stool samples. Biochemical properties of the suspect isolates were determined using conventional methods. Besides, antibiotic susceptibility tests and ESBL, carbapenem, acquired AmpC screening and confirmation tests were applied to the identified isolates to phenotypically determine beta-lactam resistance. Beta-lactam, aminoglycoside, fluoroquinolone, tetracycline, chloramphenicol, and sulphonamide groups were used to determine the multidrug resistance. Isolates with resistance to 3 or more of the antibiotic and Sulphonamide groups were accepted as multidrug-resistant isolates. Klebsiella pneumoniae was isolated from 2 (3.7%) of 54 budgerigars, and 1 (2.3%) of 42 parrot faecal samples from 3 (3.1%) of 96 faecal samples in total. No phenotypic resistance was detected in any of the isolates as a result of screening and confirming tests for ESBL, carbapenem, and acquired-AmpC resistance to determine phenotypic antibiotic resistance of the isolates. Multidrug resistance was detected in only one isolate. The presence of multi-resistant Klebsiella pneumoniae in cage birds that have close relationships with humans has been revealed.

Published: July 2021

The business process of an organization can’t be done properly without appropriate information management, in which information is an important asset that needs to be protected with the utmost care and concern. Information security is a way to protect information from large scale threats, thus to ensure the sustainability of the organization's operational, to reduce business risks and to increase business opportunity and return of investment. This research is conducted to measure the accountability of ISO 27001 in assisting the organization to document the information security policy. ISO/IEC 27001:2005 is a standard of information security that is widely used, openly accepted and implemented, and suitable for providing rules related to implementation and evaluation of the information security system. The assessment from ISO controls and objectives will be converted into a triangular fuzzy number to help in the analysis purpose. The fuzzy number is used to simplify the measurement. The result shows that the organization is not yet complying with the standard procedures of the Information Security Management System so it is needed to document the security policy based on the ISO 27001 framework standard.

Authors: Jamal Farrukh , Reyad Hesham Mohammed , Nasir Muhammad Arslan , Chesneau Christophe , Nasir Jamal Abdul , Ahmed Soha Othman
Published: July 2021

A new four-parameter lifetime distribution (called the Topp Leone Weibull-Lomax distribution) is proposed in this paper. Different mathematical properties of the proposed distribution were studied which include quantile function, ordinary and incomplete moments, probability weighted moment, conditional moments, order statistics, stochastic ordering, and stress-strength reliability parameter. The regression model and the residual analysis for the proposed model were also carried out. The model parameters were estimated by using the maximum likelihood criterion and the behaviour of these estimated parameters were examined by conducting a simulation study. The importance and flexibility of the proposed distribution have been proved empirically by using four separate data sets.
Mi idea de caracol es otra
Authors:   Università La Sapienza, Roma, Vasapollo Luciano
Published: July 2021

La imagen del caracol está impresa en las publicaciones sobre la «comida lenta» (slow food) para simbolizar la necesidad de volver a una vida que recupere los ritmos naturales. No obstante, en las sociedades de producción capitalista esa idea es poco factible sin la socialización de los medios de producción y sin la participación de los movimientos locales reales en la reapropiación y transición al socialismo. Por ello mi idea de caracol es otra. El problema debe afrontarse en términos de los conflictos de clase de campesinos, indígenas, obreros y sujetos sociales de las economías locales dentro del conflicto capital-trabajo y las luchas por la defensa y socialización de los bienes comunes. Es inevitable analizar la capacidad política de los movimientos campesinos y obreros, de los movimientos locales; como también lo es la necesidad de recuperar el patrimonio identitario y cultural que está hoy en riesgo de desaparecer debido a la especulación, el consumismo y la pérdida de memoria histórica. Es importante que en la construcción de una sociedad nueva y de su idea de desarrollo se busque un progreso equilibrado, complementario y solidario, socio-ecosostenible y autodeterminado, que se opone al desarrollismo capitalista fundado por la explotación del trabajo. No obstante el vértigo de la sociedad capitalista, la lentitud puede ser la de la historia, que a su vez puede ser tremendamente veloz; pero es, sobre todo, la lentitud del cambio.

Pro-Kontra Normalisasi Hubungan Diplomatik Israel-Sudan
Authors: Ulum Muhammad Bachrul
Published: July 2021

Pada tahun 2020, empat negara Arab melakukan normalisasi hubungan dengan Israel, yakni Uni Emirat Arab (UEA), Bahrain, Sudan, dan Maroko. Sudan selama ini dikenal sebagai negara pengusung paham Pan-Islamisme garis keras selama masa pemerintahan Omar Al-Bashir, sehingga normalisasi hubungan dengan Israel ini sangat mengejutkan. Tujuan penelitian ini adalah untuk menjelaskan alasan di balik persetujuan Sudan terhadap tawaran normalisasi dari Amerika Serikat tersebut. Penelitian ini menggunakan metode kualitatif dengan pendekatan historis untuk melacak penyebab terjadinya normalisasi serta memanfaatkan konsep “kepentingan nasional” dalam kebijakan luar negeri. Penelitian ini menemukan bahwa kesediaan Sudan untuk menormalisasi hubungannya dengan Israel adalah bagian dari upaya negara itu untuk keluar dari daftar State-Supported Terrorism versi Amerika Serikat. Status tersebut selama ini dianggap oleh pemerintah Sudan sebagai ancaman terhadap kepentingan nasional mereka, terutama di bidang ekonomi.

Published: July 2021

Pada akhir 2013, Iran menyepakati kesepakatan bersama P5+1 yang menjadi cikal bakal Joint Comprehensive Plan of Action (JCPOA) yang ditandatangani pada 14 Juli 2015. Keputusan ini diambil Iran dengan tujuan agar dunia internasional memberikan pengakuan terhadap program nuklirnya dan mencabut sanksi terhadap negara tersebut. Sebelumnya, sejak tahun 2003 hingga 2012, Iran selalu menolak berunding dengan Barat. Fenomena ini memunculkan pertanyaan penelitian yang dibahas dalam artikel ini, yaitu apa penyebab perubahan kebijakan Iran terkait proyek nuklirnya. Penelitian dilakukan melalui studi pustaka dengan memanfaatkan dokumen-dokumen resmi dan pemberitaan media massa. Dalam penelitian ini, penulis menggunakan teori pengambilan kebijakan luar negeri yang dijabarkan Snyder, et. al. Hasil yang didapatkan adalah perubahan ini dipengaruhi oleh faktor internal, terutama dinamika politik dan ekonomi di bawah kepemimpinan Presiden Hasan Rouhani. Faktor eksternal juga menjadi pendorong bagi Iran untuk mengubah kebijakannya, antara lain perubahan kebijakan yang dilakukan Obama pada periode kedua kepemimpinannya yang mendapat dukungan Uni Eropa, Rusia, dan China.

Artikel ini menjelaskan faktor-faktor yang memengaruhi kebijakan luar negeri Iran terhadap Arab Saudi pascaeksekusi mati Nimr al-Nimr pada tahun 2016. Nimr al-Nimr adalah ulama Syiah yang dihormati di Timur Tengah. Iran sebagai negara dengan populasi penganut mazhab Syiah terbesar di dunia bereaksi keras atas tindakan Arab Saudi tersebut sehingga hubungan kedua negara memburuk, bahkan berujung pada pemutusan hubungan diplomatik. Pertanyaan penelitian yang diajukan adalah faktor-faktor domestik apakah yang memengaruhi kebijakan tersebut? Dalam riset ini, periset menggunakan metode riset kualitatif dengan pengumpulan data melalui wawancara pada sejumlah pakar Timur Tengah dan menelaah literatur, dokumen, dan media massa. Dalam menganalisis, periset menggunakan teori dari Mintz dan DeRouen mengenai tiga faktor domestik yang memengaruhi kebijakan luar negeri suatu negara, yakni kepentingan ekonomi, peran opini publik, dan siklus elektoral. Hasil riset ini adalah kebijakan luar negeri yang diambil Iran pascaeksekusi mati Nimr Al Nimr sangat terkait dengan kepentingan ekonomi, terutama terkait pelaksanaan ibadah haji; sejalan dengan opini masyarakat Iran yang sangat menghormati Nimr Al Nimr; dan pertimbangan siklus elektoral, dimana kebijakan yang diambil Rouhani berpengaruh pada kemenangannya dalam pemilu tahun 2017.

Authors: & et al. Mardiana
Published: July 2021

This study was aimed to investigate the effect of combining sawdust (SD), filter cake (FC) and calcium carbonate as growth medium for the production of white oyster mushroom. Isolate F2 oyster mushroom was cultured on malt extract agar (MEA) and used in the experiment. The culture medium consisted of two treatments: first, A treatment: combined medium (A0=100% SD; A1=100% FC; A2=70% FC and 30% SD; A3=50% FC and 50% SD; A4=30% FC and 70% SD) and second, K treatment: addition of calcium carbonate (K1=2%; K2=3%; K3=4%; K4=5% weight of medium). A Randomized design was used to analyze certain parameters, such as mycelial growth, presence of fruiting body, the number of fruiting bodies and the fresh weight of fruiting body at harvest. The results showed that the highest mycelial growth and fruiting body formation occurred on A0 treatment. However, a high number of fruiting bodies and a high fresh weight of fruiting body at harvest were obtained on A4 treatment. Interaction between the combined medium (A) and addition of calcium carbonate (K) showed that the highest mycelial growth occurred on A0K2 treatment 30 days after incubation. The composition of A4 treatment (30% FC and 70% SD) was found to be the optimal medium for the production of fruiting body. This finding shows that FC with additional nutrition could as a substitute of SD medium for cultivating white oyster mushroom.

One of the great problems of computing is preserving the security, condentiality, and integrity of the information. Biometric systems consist of
identifying some physiological trait of an individual, focusing on information security aspects where the objective is the identication and
authentication of individuals to give them access to certain information. The rst stage of a biometric system consists of the segmentation of the
area to be identied, which is why this work shows a methodology that allows obtaining the segmentation of the vascular network of the back of the
hand in infrared images, furthermore, the methodology allows to determine the skeleton of the vascular network.

A busca pela excelência acadêmica tem enfatizado a importância de diversas ações buscando impactos positivos na área educacional. Nesse contexto, é conhecido que, num curso como o de licenciatura em Física, dificilmente os licenciandos conseguem concluir sua formação no prazo previsto, podendo ainda procurar outros caminhos ou oportunidades. A evasão e a retenção em cursos de graduação são fenômenos complexos decorrentes de diferentes motivações e que necessitam ser estudados, buscando assim, possíveis falhas nos processos de ensino e aprendizagem. Este trabalho analisou, de forma não interventiva, estes fenômenos na disciplina de Química Geral, buscando identificar possíveis causas e estratégias para redução dos mesmos. Problemas como infraestrutura, transporte escolar, acolhimento dos estudantes, metodologia, condições econômicas, falta de afinidade com o curso e formação básica são alguns dos fatores descritos com um maior destaque negativo. A literatura relata que, em alguns casos, ações que aumentem o vínculo do estudante com a instituição, e que propiciem melhorias do ensino e de assistência estudantil são fundamentais e contribuintes para a redução da evasão e retenção dos estudantes.

A aproximação entre trabalho e educação pode ser identificada desde os estudos das comunidades primitivas, onde as tribos criavam métodos de produção de sua existência e desenvolviam processos que serviriam de ensinamentos para as novas gerações. A educação profissional tem avançado no Brasil, apesar de ainda focar em uma formação majoritariamente tecnicista e, portanto, minimizar as possibilidades de ampliação formativa. As mudanças no mundo do trabalho estão ocorrendo em uma velocidade nunca vista antes, o que torna um desafio pensar em práticas pedagógicas que aproximem o aluno da realidade atual. Diante desse desafio, o Projeto Laboratório de Prototipagem (LAB IFMaker) do IFCE apresenta-se como uma estratégia integradora da metodologia Learning By Doing com a implementação de laboratórios para serem utilizados na formação. Neste sentido, objetivou-se
identificar potencialidades de inovação do Projeto Laboratório de Prototipagem Lab IFMaker  em soluções criativas e eficientes nos processos de ensino do IFCE de modo a integrar a comunidade acadêmica. A pesquisa foi realizada com a abordagem qualitativa e o método estudo de caso. Na primeira fase do percurso investigativo, deram-se os estudos dos fundamentos teóricos acerca da categoria formação para o mundo do trabalho. Posteriormente, tendo o projeto Lab IFMaker do IFCE como objeto de estudo, caracterizaram-se os pressupostos multidisciplinares e integradores do fenômeno em análise.
