Authors: Malekmohammadi Laleh , Sheidai Masoud , Ghahremaninejad Farrokh , Danehkar Afshin , Koohdar Fahimeh
Published: May 2023

The genus Avicennia contains of 8 species which show a great extent of morphological and genetic variability, which make taxonomy of the genus difficult. Molecular barcoding along with advancement in computational approaches may be proper methods to investigate and assess the efficiency of different molecular genetic regions in Avicennia species delineation and also produce data on species evolution and divergence. The aims of present study were to utilize multiple genetic data for the species delineation and study the phylogeny of the genus. Moreover, we developed a hypothesis on biogeography of these species with respect to barcode divergence. The results showed that both Internal transcribed spacer (ITS) and trnHG–psbA intergenic spacer (trnHG-psbA) sequences may be used in Avicennia species delineation. Barcode gap analysis and nucleotide difference of the studied taxa showed significant Fst for pair-wise species comparison and the role of nucleotide changes in Avicennia speciation.

Sex determination of date palm seedlings is the challengeable effort for breeders. Different studies based on molecular markers and genome sequencing have provided some insight in to the genetic regions related to sex determination in date palms in general. But due to differences in cultivar population structure and also cost of whole genome sequencing, we may need a more suitable approach in developing countries for this task. Therefore, we suggest using a combination of different available molecular markers and a computational approach to identify the genetic regions involved in sex differentiation in date palm cultivars. In this study we used twenty-three cultivars including 7 male and 16 female cultivars that were examined by 30 different dominant and co-dominant molecular markers which deal with different genomic regions. Grouping of the tree samples based on 178 loci resulted in genetic differentiation of the studied male and female palm trees. Multiple correspondence analysis (MCA) bi-plot also showed genetic difference within male and female trees. Heatmap plot specified those markers which differentiate date palm trees. SSR (simple sequence repeats) and IRAP (inter retrotransposon amplified polymorphism) markers provided sex linked markers for male cultivars. In present study, we introduced sex specific alleles for Iranian male date palm cultivars as a fast track in seedlings. Different association studies performed identified the candidate genetic regions which are significantly associated with sex differentiation in date palm cultivars.
Ethopolítica: Desarrollo como política. Una reflexión desde la educación y el desarrollo humano
Authors: Alvarez López Mario Alberto , Arboleda Julio César
Published: May 2023

La Ethopolítica: El Desarrollo como política, expone la necesidad de desarrollar una reflexión sobre la educación superior en Colombia: las tensiones entre política pública y desarrollo3 , como expresión de los soportes teóricos que le dan sustento a la concepción imperante en el sistema educativo en Colombia, donde se expresan valores, costumbres y hábitos que configuran nuestras formas de ser y de pensar, los cuales, presumiblemente, se encuentran mediados por la ideología y presupuestos sobre los cuales descansa el proyecto de modernidad europea y de occidente en general. 

En efecto, hoy la educación está cruzada por múltiples representaciones, sociabilidades e ideologías que el investigador debe interpretar y desvelar en el propio contexto de los problemas de indagación y de las tensiones que se producen en los discursos hegemónicos que subyacen a los procesos de modernización educativa, expresados en las orientaciones de la política pública que regula la materia, desconociendo condiciones contextuales en lo histórico, social, político y cultural, propias de otras circunstancias y posibilidades de los territorios diversos del país colombiano. En este sentido, es necesario reconocer que en condiciones particulares y de especificidad territorial se movilizan formas distintas de situarse, en términos ethopolíticos, frente al desarrollo, la sociedad, la educación y lo humano.

Authors: Pereira Coelho João Paulo , Da Silva Moreira Jani Alves
Published: May 2023

El propósito del artículo es analizar la Ley nº 13415 a partir del proceso histórico-político y económico brasileño. Se trata de comprender cómo las transformaciones en las relaciones de producción subsidiaron la concepción de educación y trabajo presente en la referida ley. Es el resultado de una investigación cualitativa, en la que se adoptó la investigación documental y bibliográfica como procedimientos de recolección y análisis de datos. La metodología, de análisis crítico y contextualizado, se basa en el marco teórico histórico, en el que considera las políticas educativas como elaboraciones producidas en un contexto de múltiples contradicciones. Se concluye que las crisis económicas posteriores a la década de 1970 profundizaron la aplicación de tecnologías a los medios de producción. La Ley nº 13.415/17, condicionada por los cambios en el mundo del trabajo, expresa estas sociabilidades emergentes. Lo que, a su vez, significó el auge del uso de la tecnología computarizada y la inteligencia artificial algorítmica en la relación enseñanza-aprendizaje, así como en el mundo estudiante-trabajo.
My Husband! If you were the Good Husband, you would be able (曲) to give (扌) me the most Precious Thing, Even the Star in the Heaven (辰) (Tcheonzamun 641st-656th)
Authors: Kim Sangdeog Augustin
Published: May 2023

French Missionary Dallet (1874) wrote in his book that ‘the thousand character essay’ had been used as a textbook for Chinese character for the children in the ancient China. ‘The thousand character essay’ is in Korea called as ‘Tcheonzamun (千字文)’, and the Korean people deeply believe that Chinese people has created this famous book (Tcheonzamun) (Han, 1583). However, recently Park et al., (2021a) and Park et al., (2021b) suggested that Tcheonzamun possibly has been created by Korean-speaking people. There are two translating methods. The first method is through Korean pronunciation of Chinese character, and the second one is through the meaning of Chinese character in Tcheonzamun. Both the pronunciation of Chinese character in Korean language and the Chinese character itself is dependent on somewhat old book of Tcheonzamun (Han, 1583). Additionally, the method of deletion was used in this work. The same part of Chinese character was deleted in the range of same line. In this work, a line means the 4 Chinese characters. For example, (653-656 務(Mu) 玆(Za) 稼(Ga) 穡(Saeg)) is a line. And the translation through the meaning of Chinese character will be done with the remained part after the deletion. The thousand character essay is in Korea called as ‘Tcheonzamun’ (Han, 1583). This is the work of translation of Tcheonzamun poem. The title of this study is ‘My husband! If you were the good husband, you would be able (曲) to give (扌) me the most precious thing, even the star in the heaven (辰) (Tcheonzamun 641st-656th)’. This is the first method of this translating work. It is through Korean pronunciation of Chinese characters in this Tcheonzamun poem (Tcheonzamun 641st-656th). The theme of this Tcheonzamun poem is as follows. My husband! I(your wife) am smaller (幺) and smaller (幺) than you! Do you want me to work (務) well for you? My husband! Can you hear my hope? Here, this is my desire! I want to say (口) to you freely at our home (家), and I want to express to you my opinion (口) freely in our life (土)! And the miserable wife says her secret in her mind. “My husband! If you do not accept my sincere hope”, “My husband! From now on, I shall come (Ga_se!) to another man! (Mut_hyeo)”.

Published: April 2023

What is permanent in this world is change. The world is on the move and technology is affecting every aspect of life and the education sector is not left behind. Presently, the education sector is going through several changes, and the old-fashioned technique of teaching-learning is no longer suitable for the digital and/or knowledge-based society. Student enrolment rate is constantly on the increase on daily basis. Consequently, future education needs digitally skilled teachers to respond to the futuristic pedagogy that will respond to the learning needs of 21st-century generation students. Futuristic education is a type of modern teaching-learning that will encourage classroom engagement and enlargement, and learning for students to use modern or technological approaches to instruction in educational institutions that will facilitate students’ intellectual, social, and emotional development. This study reviewed some vital literature, reviewing some scholarly publications on the topic by x-raying vital contributions made by various researchers and/or scholars, and institutions. The paper correspondingly attempts to identify current teachers’ challenges that will hinder the future teaching-learning process, and offer possible suggestions that will meet the future needs of higher education, particularly in the Nigerian context. The significance of the study is to remind teachers to build their technological skills for futuristic teaching- learning by using technologies effectively, and also offer them the opportunities to address the present challenges confronting the modern teaching approach to effectively organize how students’ engagement will be carried out in the future, with the hope of providing quality education for all learners.

Authors: P Makungu, A. , G Kengue, , D Moubissa, , M Roukaya,
Published: May 2023

Introduction: Persistent oral bleeding in a child may be a sign of a bleeding disorder. The objective of this work is to describe the diagnostic and therapeutic aspects of hemophilia. Observation: We report the case of an 11-month-old male infant who had been admitted to the maxillofacial surgery department for persistent post-traumatic gingivorrhagia in a patient with no particular history. The clinical examination noted a wound with a layer of gingival bleeding, hematomas in the two upper limbs. Biological exploration revealed normochromic microcytic anemia at 6.5 g/dl; 97% prothrombin rate. The treatment consisted of gingival suture with tranexamic acid compression dressing, vitamin k injection and transfusion of 2 iso-group, iso-rhesus blood bags. The persistence of bleeding led to a search for coagulation factors, with factor VIII returning to less than 1%, concluding with the diagnosis of hemophilia A. Transfusion of an iso-group iso-rhesus blood bag to stop the bleeding. Transfer of the patient to the hematology department for specialized care. Discussion: Any unusual bleeding from the cephalic and bucco-facial sphere in an infant should raise the question of hemophilia. Conclusion: Stomatorrhagia is the evocative sign and the suture accompanied by blood transfusion a means of treatment.
Presentation of Public Speeches in the Framework of Gricean Maxims: A Case Study of Kakamega County
Authors: Chenenje Solomon Luvonga
Published: April 2023

Public speaking has continually become authentic without which communication can take place among the people of any society, and therefore there is a need to scrutinize whether or not they conform to Gricean maxims or violate them. Grice's principle of 1975 gives the conventions by which a successful speech can be uttered. The key objective of the study is to analyse the type of speeches that conform to Gricean maxims and the maxim which is susceptible to violation. The types of speeches include persuasive, informative, and ritualistic. Descriptive research design was adopted and the target population was people of Kakamega County. Convenience sampling technique was applied to gather the speeches from the church, funerals, marriage ceremonies, learning institutions, media platforms, graduation ceremonies, and seminars. Secondary sources of data include speeches from the president and the governor. The research instruments included audio-tape recording, oral interview and observation until saturation stage was attained. Data was analysed in the table and textual form. It was found that ritualistic speeches flouted the maxim of quantity and manner. Persuasive speeches mostly violated three maxims. Most of the informative speeches conformed to all maxims. It therefore, recommends that ritualistic speeches are specific and mostly written and should not take more than 5 minutes. Persuasive speeches mostly flout the maxim of quality, quantity, and manner because some are informal and figurative. Informative speeches are formal and time-bound, therefore, conform to the maxims. Since Gricean principles could not account for political speeches, relevance theory was applicable to cover the deficit.

This study investigates the chemical composition of mistletoe leaves growing on fig tree. The mistletoe leaves and the fig leaves used for this research were harvested from Fig plant. Proximate analyses, phytochemical screening, Elemental and antioxidant analysis were done on both leaves. This study has provided a scientific justification that both the Fig leaves and Mistletoe leaves contained relevant phyto constituents such as alkaloids, saponins, flavonoid, and steroids; whereas antraquinones, tannins, phenols, resins and terpenoids were completely absent. Nutritionally relevant inorganic minerals like, Calcium, magnesium and potassium were the most abundant element in both plants. Proximate constituents like carbohydrates, lipids and proteins were present in varied amounts in both leaves. Result of inhibition of free radicals in fig leave extract increases with increase in concentration of the extract. The inhibition is closely comparable with that of the standard (Vitamin C) at the same concentration. The inhibition by the extracts of mistletoe grown on fig tree is low when compared with that of Fig and that of standard. This suggests that some of the chemical characteristics of mistletoe are conferred to them by their host trees.

Published: April 2023

Escherichia coli, a Gram-negative rod organism and the commonest urinary pathogen causing 60-90% of Urinary infections. Two virulence genes (Pap C and hlyA) had been reported to be involved in Escherichia coli pathogenicity and its resistance to antibiotics. The study aimed at detecting PapC and hlyA in E. coli isolated from clinical specimens in two main Tertiary hospitals (Federal Medical Centre and Niger Delta University Teaching Hospital) in Bayelsa State. One hundred and forty-five specimens were collected and analyzed using the standard Bacteriological technique. Antibiotics Susceptibility testing was carried out using the Kirby Bauer method and Polymerase Chain Reaction (PCR) was employed using ABI 970 amplified Biosystem thermal cycler. The susceptibility pattern showed that 18(90%) isolates were resistant to Nalixidic acid, 16(80%) to Ampicillin, 15(75%) to Ceporex, 14(70%) to Septrin and Augmentin, 12(60%) to Reflacine, 11(55%) to Ciprofloxacin, 9(45%) to Gentamycin, 8(40%) to Tarivid and 4(20%) to Streptomycin. Fifteen PCR products were resolved on 1.0% agarose gel, out of which 8(53.3%) harboured Pap C while 1(6.7%) harboured hlyA. Seven of the eight Pap C-carrying isolates were susceptible to Ciprofloxacin while the HlyA virulence gene enhances the resistance of the organism to Ciprofloxacin. Therefore, the E. coli Pap C gene may be incorporated into Ciprofloxacin production to curb antibiotic resistance.

Antimicrobial resistance continues to pose serious public health challenges. OqxA and OqxB are multidrug resistance genes that confer Escherichia coli and Klebsiella pneumoniae resistance to more than one antibiotics. The purpose of this study was to detect OqxA in Escherichia coli and OqxB in Klebsiella pneumoniae from clinical samples isolated from Niger Delta University, Yenagoa. A total of 50 samples were collected. The bacterial isolates were identified using a standard bacteriological technique, the genes were detected using Polymerase Chain Reaction while the antibiotic susceptibility testing was done by disc diffusion. Of the 50 clinical isolates, 9(18%) were positive for E. coli while 15(30%) were positive for Klebsiella pnuemoniae. The total number of isolates were 18(36%) from male and 32(64%) from females. The susceptibility pattern of the isolates revealed that Escherichia coli exhibited the highest resistance of 100% to Cefuroxime and Augmentin, followed by Gentamycin and Ofloxacin (.55%) and Ciprofloxacin (11.11%) while Klebsiella pneumoniae Nalidixic Acid, Augmentin Cephalexin and Sulfamethoxazole shows 100% resistance respectively. Of the 9 that were E.coli isolates, 8(88.9%) harboured OqX A while of the 15 that were Klebsiella pneumoniae isolates, 13 (86.7%) harboured the OqxB genes. There was 100% resistance to Nalidixic acid, cefuroxime and sulfamethoxazole, with lowest resitance to meropenem (46.7%) and ciprofloxacin (60%). The report clearly demonstrates an urgent need for surveillance against these bacteria especially as they are pathogens of public health concerns to minimize the increasing pace of multidrug resistance conferred on these bacteria by OxAB genes.

Published: April 2023

Kondisi dan potensi setiap wilayah sangat beragam dengan karakteristik masing- masing. Hal ini menjadikan tingkat tumbuh dan berkembangnya suatu wilayah menjadi berbeda- beda. Karena perbedaan kondisi wilayah sehingga tingkat tumbuh dan berkembangnya wilayah menjadi berbeda maka kondisi ini menyebabkan terjadinya ketidakmerataan kecepatan pengembangan dan pembangunan wilayah atau yang disebut disparitas/kesenjangan. Kesenjangan akan menjadi masalah bila terjadi kesenjangan yang terlalu besar dan disebabkan oleh sistem pembangunan yang salah, sehingga dapat menjadi penyebab munculnya keresahan, ketidakpuasan dan bahkan sampai timbul aksi dari sekelompok masyarakat untuk memisahkan diri dari NKRI. Permasalahan mendasar pada pengembangan wilayah di Kawasan Metropolitan terutama Malang Raya adalah kesenjangan antara daerah dimana pembangunan di monosentris, terpusat pada Kota Malang. Menanggapi kondisi demikian, dibutuhkan perumusan pola kesenjangan wilayah di Malang Raya, untuk mengetahui sejauh mana pemusatan pembangunan dan pertumbuhan wilayah di Malang Raya. Selain itu diharapkan melalui perumusan pola kesenjangan wilayah mampu menjadi acuan sehingga arahan dapat meminimalkan kesenjangan wilayah di Malang Raya. Penelitian terkait pola kesenjangan ekonomi wilayah ini berlokasi di Malang Raya yang terdiri dari 3 wilayah yaitu Kota Malang, Kabupaten Malang dan Kota Batu. metode analisa yang digunakan adalah LISA (Local Autocorrelation). Dari hasil Local Indicator Of Spatial Association (LISA) bahwa kabupaten Malang High-low mengelilingi daerah kota Malang dan Kota Batu low-high, artinya belum ada kesenjangan di wilayah Kota Batu dan kota Malang namun kesenjangan wilayah di Kabupaten Malang.

Blade turbin PLTU 400 MW ditemukan dalam keadaan patah. Kondisi ini diketahui pada saat major inspection dilakukan, dimana turbin sudah beroperasi selama 35 tahun. Patah pada blade sudah terjadi cukup lama sehingga terbentuk kerak oksidasi pada area patahan. Blade tersebut terletak pada tingkat Low Pressure (LP) Turbin. Material blade adalah Stainless Steel 17-4 PH. Analisis kegagalan dilakukan untuk mengetahui penyebab patah pada blade sehingga tidak terulang kembali dan mendapatkan rekomendasi untuk operasi turbin selanjutnya. Metodenya dengan melakukan verifikasi material blade, investigasi kegagalan dengan pemeriksaan visual dan fraktografi. Hasil dari investigasi menunjukkan bahwa kegagalan yang terjadi bukan berasal dari material blade. Penyebab patah diinisiasi oleh cacat pada leading edge karena benturan benda asing atau Foreign Object Damage (FOD). Pada saat penelitian ini dilakukan FOD tersebut belum bisa diidentifikasi wujudnya.  Pada area blade yang patah terdapat bukti berupa beachmark, sehingga patah yang terjadi adalah patah fatigue. Perawatan berkala dengan interval yang lebih pendek perlu dilakukan untuk mencegah kegagalan terulang

Gas Metal Arch Welding (GMAW) adalah suatu metode pengelasan yang saat ini sudah banyak digunakan di industri manufaktur. Hal ini dikarenakan GMAW memiliki beberapa keunggulan seperti pengelasan yang cepat dan dapat digunakan dalam berbagai posisi dan material. Namun demikian, cacat pada las berupa porositas masih sering terjadi, sehingga untuk mendapatkan hasil yang maksimal melalui teknik pengelasan GMAW masih diperlukan penelitian lebih lanjut secara ekstensif. Penelitian ini bertujuan untuk mempelajari mengenai pengaruh pengaturan voltase terhadap kekuatan tarik hasil las GMAW, yang mana sangat dipengaruhi oleh porositas hasil lasnya. Dalam hal ini, material yang digunakan yaitu berupa pipa STKM 13B dan pelat SPH 440. Pengelasan antara pipa dan pelat secara saling tegak lurus memiliki kemungkinan yang besar untuk terjadinya porositas pada hasil las, sehingga sangat menarik dan penting untuk diteliti. Arus yang digunakan pada penelitian ini yaitu 110 Ampere dengan variasi voltase 18, 20, dan 22 Volt. Hasil pengelasan menunjukkan bahwa pengelasan dengan voltase yang meningkat menunjukkan peningkatan kekuatan tarik dari material yang sudah dilas. Namun demikian, pada sampel dengan voltase 20 V menunjukkan hasil terbaik yang terjadi dikarenakan pada hasil foto mikro terlihat bahwa pada sampel tersebut tidak terdapat porositas atau paling tidak minim porositas. Lebih lanjut lagi, nilai standar untuk area las menunjukkan bahwa pengelasan dengan voltase yang tinggi mendukung tercapainya standar ketebalan, kedalaman, dan panjang las yang disarankan. Penelitian ini berhasil memberikan gambaran hasil kekuatan tarik dari las GMAW pada material pipa dan pelat dengan perbedaan nilai tegangan

Published: May 2023

One of the factors causing changes in land use is the increasing population. Also, the increasing number of people causes the need for land to increase. In regulating and planning the land use of an area, the government establishes a technical reference in the form of legislation regarding the use of space in an area. Regulation is developed according to the characteristics and needs of the government in the area. Thereby, regional development can be managed and directed according to the use and utilization of the land. Regulations on spatial use are then outlined in a map, i.e., the Regional Spatial Plan Map, making it easier for the government to control, supervise, and plan regional the management and use of regional land properly. This study aims to map land-use changes on Jalan Jenderal A.H Nasution Medan in 2006, 2013, and 2020. Primary data is a mapping of land-use changes obtained from field observations and aerial photos in 2006, 2013 and 2020 obtained from the Dinas Housing, Settlement Areas and Spatial Planning of Medan City. Also, secondary data in the form of Regional Head Regulations were then analyzed using descriptive analysis techniques. The findings of this study serve as an evaluation for the government in making land-use regulations so that these regulations can be targeted and meet the community's needs.

Tourism is a vital driver of the global economy, Zambia inclusive. According to the World Travel and Tourism Council (WTTC), the direct contribution of travel and tourism to world GDP in 2012 was US$ 2.1 trillion. However, the tourism sector is highly vulnerable to climate change. This is because tourism depends on environmental resources while climate defines the length and quality of tourism seasons. At the same time, tourism contributes to the emission of greenhouse gases (GHG), the cause of global warming. Many types of tourism in Zambia are weather dependent and by extension, climate dependent. It is, therefore, very likely that climate change may affect tourism sector in Zambia. Climate change can reduce, increase and prolong heat waves or change the patterns of annual rainfall received in Zambia. Using literature review, this paper presents direct impacts and indirect impacts of climate change to the tourism sector and also proposes response strategies to climate change mitigation and adaptation in the Zambian context. Responses such as mainstreaming ESD, teacher education, research engagement, community-based approach, sustainability education among others are proposed.
