Considering the brainwave of the psychological approach for the use of Information and Communication Technology (ICT), collaboration, expectation, and motivation have been identified as the aspects of readiness for integrating technology into the teaching strategies. Studies have investigated the integration of ICTs in the teaching/learning process; still there is a lack of research probing the significance of the psychological readiness of teachers on their perceptions about utilizing ICTs in the Algerian EFL context. The research, between hands, aspires to bridge the gaps, reveal the significant obstacles; and barriers encountered while exploring ICTs, and investigate the following query: What are the significant psychological obstacles that might prevent the effective implementation of ICTs? A mixed-method design was used in this research, employing a survey questionnaire and semi-structured interview to collect data from thirty- five EFL teachers at the University of Mohammed Ben Ahmed in Oran; Algeria. Participant teachers reveal a satisfactory willingness for using education technologies. Lack of training, insufficient ICT skills, technology anxiety, resistance to change, and no perception of benefits were the major psychological obstacles reported by the informants. To perk up the digital proficiencies of teachers, to train them to utilize ICTs, and to explore the potential of ICTs were highly recommended to rouse in teachers, the emotional readiness to implement Information Technologies.

Published: July 2022

Making transport sentences requires taking into account many external and internal factors dependent on changes taking place on the shipping market. The place, time and type of transported cargo, etc., have an impact on the complexity of the transport system structure, which is why it is important to explore the possibilities and create transport optimization models throughout the entire cargo supply chain and analyze issues related to their organization, which affects the safety and reliability of this type of systems. The aim of the article is to present and analyze the concept of the agro cargo supply chain model using inland navigation, in the relations between Poland and the Federal Republic of Germany on the example of the Capital Group OT Logistics S.A. (OTL SA Capital Group). Taking into account the complexity and structure of transport tasks, it is important to look for optimal solutions in the field of transport. Each supply chain model includes only certain selected factors that have a limited impact on the volatility of the transport. It is not possible to build a model that would fully recreate the behavior of the object, with all possible external influences. The article considers the optimization model of inland wheat transport to final consumers, which predicts a constant demand for cereal loads in certain time segments. This model does not provide any rapid domestic fluctuations in demand for wheat at certain time intervals.
The use of artificial intelligence methods in the analysis of the results of vehicle braking deceleration tests in the diagnostics of the braking system of a motor vehicle
Authors: Dobaj Krzysztof
Published: July 2022

The article presents the concept of using an artificial neural network to approximate the parameters describing the vehicle braking process, from the point of view of the application of this method in the diagnostics of the braking system. The artificial neural network of non-linear autoregression was used to approximate the dependence of the braking deceleration and the pressure in the braking system. The effectiveness of the neural network was checked depending on the number of neurons in its hidden layer and on the applied learning algorithm. The operation of the neural network was verified based on the actual braking processes of the Skoda Octavia, carried out with different dynamics, with different car weights and different tire inflation pressures. After verifying the neural network, it was used to approximate the braking deceleration values for the pressure values exceeding those present in the input data set. This action allows the analysis of the possibility of the vehicle obtaining a braking deceleration, which qualifies its braking system as efficient. Two concepts of using a neural network to solve this problem were analyzed. Conclusions related to the validity of the development of the discussed methods were drawn.
Fuel lubricity and its laboratory evaluation
Authors: Wojtyniak Małgorzata
Published: July 2022

This literature review paper discusses the subject of lubricating properties of liquid hydrocarbon-based fuels and laboratory bench tests applied in lubricity evaluation. The analysis was made in order to highlight the importance of fuel lubricity evaluation, especially application of relatively rapid laboratory tests. Inadequate lubricity may lead to an excessive wear of fuel injection system components and in some cases ? even to catastrophic failure what, in turn, manifests itself in higher replacement costs, shortened service life, inefficient engine performance and increased tailpipe emissions. Nowadays, when more and more rigorous emissions standards for transportation fuels are continuously established, the satisfactory fuel lubricity is of great importance. Lubricity determines the antiwear behaviour of the lubricant over the regime of boundary lubrication when the moving surfaces are separated only by a very thin fluid film adhering to them. The most important role in forming such films is played by polar compounds and aromatic hydrocarbons that are naturally present in crude oil derived fuels. However, the refinery processes applied in fuel production remove them, thus reducing the lubricity. Fuel lubricity problems were first defined in the mid-1960s and resulted from more severe refining and treatment processes applied in the production of aviation kerosene. In those days, injection equipment failures in aircraft turbine engines were reported. Then, in the late 1980s, similar problems were revealed after the implementation by US and NATO forces of ?The Single Fuel Forward? policy which mandated that all military vehicles must be operable with kerosene-based fuel. Lubricity problems regarding diesel fuel emerged in the late 1990s when some countries set limits on the sulphur and aromatic hydrocarbon content in this fuel. The paraffinic diesel fuel produced by the Fischer-Tropsch synthesis or hydrotreatment process that is more commonly applied nowadays also possesses very low lubricating properties. Generally, to provide good fuel lubricity, various additives are applied and bench tests are mostly employed to estimate their effectiveness. Since 1960 many test rigs have been developed. Several inter-laboratory test programs were carried out to select the best bench tests that would show good correlation with field experience. Among them, only BOCLE, HFFR, and SLBOCLE test methods become industry standards.

Published: July 2022

Oryctes rhinoceros is an important pest in oil palm plantations. Adult stage of the beetle causes damage, however larval stage is very important to be controlled to break the cycle of life. An entomopathogenic bacterium Bacillus thuringiensis is one of biological agents to control these insects. Its toxic protein content provides specific insect targets as stomach poison. Objectives  of the research was to study the impact of B. thuringiensis propagated in bio-urine enriched with 5 per cent molasses towards  Oryctes larvae. The research was carried out in the shade house of Plant Protection Study Program, Faculty of Agriculture, Sriwijaya University from August to November 2021. Experiment was designed in a randomized complete block design with 7 treatments and 4 replications. A total of 20 ml of bio-insecticide was dissolved in 280 ml of water, sprayed evenly on the soil mixed with  male palm flowers as feed of larvae. The treatments were 6 isolates of B. thuringiensis isolated from soil in oilpalm plantation, namely with codes:  C14, C15, A15, OJ, BK, and LK as well. The results showed density of B. thuringiensis spores in bio-urine media was different in each isolate. The highest spore density in isolate code LK was 4.83 x 1010 spores/ml and the lowest (in isolate A15) was at 3.5 x 1010 spores/ml. Mortality rates were significantly different between isolate treatments starting from day 3 to day 12 of observation. C15 isolate lead the highest mortality rate of 100% on day 12 while other isolates showed mortality data below 100% (88-98%). Body weight and length showed significantly differences on days 0, 6 and 12 after application. Symptoms of infection begin with a change in skin color from white to brown, dark brown and black. Death is characterized by a soft body texture and wet rot.

The main purpose of this study was to find out what complaints were conveyed by customers through online reviews of one of the five-star resorts in Lombok. To find out, we conducted a content analysis of 314 negative reviews posted on the travel website TripAdvisor. To find out what complaints were conveyed by customers in their reviews, we used the JMP Pro14 software to analyze the datasets we had collected. Before presenting the main research findings (words/terms and phrases), this article provides an overview of some of the data elements that are an integral part of the main unit of analysis. For example, frequency distributions (ratings, reviewer contributions, word count, and length of stay), tables (including the reviewer's country of origin), and visualizations that compare the number of contributions and the rating given by a reviewer. The main result of this study found that the complaints on the three ratings in negative reviews were most often about "room" (referring to rooms that are old and need renovation) and "beach" (dirty and lots of garbage). Interestingly, despite their low aggregate rating, their assessment of "staff service," most reviewers gave a good rating. However, reviewers give some suggestions to hotel management, one of which is to improve their staff's English skills.

Analysis of CFRP Confined Concrete Cylinders by using ABAQUS Software
Authors: Hardan Samah Ahmed , Aules Wisam Amer
Published: July 2022

The fiber-reinforced polymer (FRP) wrapping is widely used in concrete column strengthening, as it can enhance concrete strength and ductility. This study aims to develop finite element numerical model that can capture the behavior of the short cylinder column confined with CFRP. After validating the proposed finite element models with previous experimental works, a series of parametric studies have been conducted, including, CFRP number of layers, concrete grade, confinement configuration, and size of samples are investigated in terms of stress-strain curves, ductility, and volumetric strain. The results indicate a significant improvement in concrete strength after fully CFRP wrapping. However, the partial confinement records less improvement in concrete strength but considerable ductility. By increasing the specimen’s size and maintaining the same confinement ratio, the strength enhancement was decreased. Based on this observation; it can be concluded that; by increasing the samples sizes, it should be escorted with more confining ratio than that of the small size. Moreover, it was concluded that as the number of layers increases the ductility increases whether it was full or partial confinement configuration. The CFRP confinement can control the specimen’s dilation during the axial compression test thus presenting less volumetric strain. The proposed formula by (Lam & Teng, 2003) that can predict the stress-strain response of FRP full confined concrete cylinder was compared with the corresponding values. The results indicated that; a good matching was noticed only for the samples located in the same area that was studied by (Lam & Teng, 2003).

The COVID-19 era presents many obstacles for students to study and gain knowledge about physical education, so it is necessary to use textbooks thus enabling them to master the subject matter more optimally. The purpose of this study was to determine student perceptions at the university level about physical education learning model textbooks during COVID-19. This research uses mixed methods. Twenty five subjects from sports students at Halu Oleo University are willing to contribute to this research. Quantitative data collection techniques are through questionnaires while qualitative data collection is through in-depth interviews. The results of the research quantitatively found that most of the subjects had a very agreeable perception of the use of textbooks in the COVID-19 era. While the results of qualitative research indicate that the majority of subjects give the perception that physical education learning model textbooks have quality material content, use of language and good design.  In addition, they consider that physical education learning model textbooks are pedagogical tools that have many benefits when used during the COVID-19 pandemic, one of which is to increase knowledge.  Therefore, one of the efforts that can be made so that sports students have the willingness to learn during the COVID-19 pandemic is to provide quality textbooks.

Na pós-modernidade, informações e conhecimentos são produzidos e divulgados por meio das tecnologias, especialmente pela internet e mídias digitais. Alunos e professores têm em suas mãos recursos que permitem acesso aberto ao saber, o que inspira mudanças e constantes invenções no campo da educação. Nas redes sociais da Internet, perfis estão sendo criados para explicitar materiais e/ou rotinas de estudo, com intuito de compartilhar vivências, inspirar outras pessoas, bem como divulgar e discutir temáticas relevantes, sendo conhecidos como Studygrams. Nesse sentido, objetivou-se, com a realização deste estudo, identificar tendências e contribuições dos Studygrams para o ensino-aprendizagem de Ciências e Biologia, na visão de um painel de Studygrammers que produzem e publicam conteúdos relacionados às Ciências Biológicas no Brasil. O trabalho foi desenvolvido a partir de uma abordagem qualitativa, com elementos de pesquisa netnográfica, como a observação participante e o trabalho de campo online. Os resultados evidenciaram que os Studygrams têm potencial para explorar e desenvolver competências e habilidades, tanto naqueles que postam, quanto nos que acessam os conteúdos. Entende-se que esta nova prática de ensinar e aprender em espaços informais tem despertado atitudes de empreendedorismo, autonomia, organização, interação e criatividade, que permitem a fixação dos conteúdos, a interdisciplinaridade, a contextualização e a formação para a cidadania.
Kariye Güney Şapeli’ndeki Anastasis Freski’nin Yapıt Çözümlemesi ve Mimari Programla Etkileşimi
Authors: ARIN ENSARİOĞLU Sebla
Published: July 2022

Bu makalede Kariye Manastırı güney şapelinde yer alan Anastasis freskinin ikonografik olarak çözümlenmesi ve bu yapıtın yapının mimari programıyla kurduğu ilişkinin irdelenmesi hedeflenmiştir. İlk olarak eserin yer aldığı Kariye (Khora) Manastırı mimari nitelikleri bakımından incelenmiştir. Eserin sanatçısı ve hamisi hakkında bilgi verilmesinin ardından, esere konu olan Anastasis temasının mitolojik kökeni irdelenmiştir. Anastasis freskinin yapımında kullanılan tekniğin özgün tarafları ortaya konmuştur. Yapıtın ikonografik çözümlemesi yapılırken Erwin Panofsky’nin geliştirdiği yöntemden faydalanılmıştır. Bu kapsamda Anastasis freski incelenirken ilk olarak biçimsel analizi yapılarak kompozisyonda yer alan figürlerin birbirleriyle ilişkileri irdelenmiş; ikinci aşamada teolojik ve alegorik bilgiler ışığında figürlerin temsil ettiği karakterler ve aktarılan kavramlar ortaya çıkarılmaya çalışılmıştır. Üçüncü aşamada ise yapıtın, dönemin koşulları içerisinde sahip olduğu anlamlar irdelenirken; yakın döneminde üretilen, benzer temaya sahip eserlerle de karşılaştırılmıştır. Son olarak yapının mimari ve ikonografik programları arasındaki etkileşim ele alınmıştır.Kariye Manastırı, mimari programla ikonografinin iç içe geçtiği, hatta ikonografiyle anlatılan hikaye dizisinin mimari elemanları belirlediği bir düzene sahiptir. Bu nedenle Rönesans’a öncülük yapan Bizans Sanatı ikonografisinin incelenebileceği özgün örnekler arasında sayılabilir. Kariye güney şapeli apsis yarım kubbesi üzerinde yer alan Anastasis freski, Hristiyan literatüründe önemli bir yeri olan diriliş temasını işlemektedir. Şapeldeki ikonografik programın bütünü düşüldüğünde diriliş sahnesi ana temayı oluşturmaktadır. Anastasis freskinin parekklesionda yer alması, mezarı burada bulunan Kariye Kilisesi’nin hamisi Metokhites’in ölümsüzlük / diriliş beklentisini de simgelemektedir.
