Authors: ÇOLAK Recep , YİĞİT Tuncay
Published: December 2021

Üniversitelerin her dönem başında yaptığı ders çizelgeleme problemi kombinatortal optimizasyon problemlerindendir. Çizelgeleme problemleri NP-Hard sınıfına giren ve çözümü zor problemlerdendir. Determinist bir yaklaşımla olası bütün ihtimallerin denenmesi gibi algoritmalarla çözüm mümkün olsa da çok zaman alıcı bir işlem olduğundan pratikte bu algoritmalar kullanılmamaktadır. Özelikle probleme ait veriler arttıkça ve çözülmesi gereken çok fazla kısıt olması durumunda çözüme ulaşmak daha da güçleşmektedir. Bu çalışmada ders çizelgeleme problemi çözülmesi gereken katı ve esnek kısıtlar olarak ele alınmıştır. Katı kısıtlar ders çakışması, derslik çakışması, kapasiteye uygun olmayan dersliğe şube atanması gibi kesin olarak çözülmesi gereken kısıtlardır. Esnek kısıtlar ise derslerin istenmeyen zaman dilimlerine atanması bir kısmı ihmal edilebilen kısıtlardır. Bu çalışmada probleme ait katı ve esnek kısıtlar belirlenmiş ve bu kısıtları ihlal edilen durumlara ceza puanları atanarak en az ceza puanına sahip çözümler aranmıştır. Problemin çözümü için çizelgeleme problemlerinde sıkılıkla kullanılan Genetik Algoritma kullanılmıştır. Yapılan testeler sonucunda Genetik Algoritma ile ders çizelgeleme probleminin kısa sürede çözülebildiği görülmüştür.
Improved Runge Kutta Optimizer with Fitness Distance Balance-Based Guiding Mechanism for Global Optimization of High-Dimensional Problems
Authors: CENGİZ Enes , YILMAZ Cemal , KAHRAMAN Hamdi , SUİÇMEZ Çağrı
Published: December 2021

Runge Kutta (RUN) is an up-to-date and well-founded metaheuristic algorithm. The RUN algorithm aims to find the global best in solving problems by going beyond the traps of metaphors. For this purpose, enhanced solution quality mechanism is used to avoid local optimum solutions and increase the convergence speed. Although the RUN algorithm offers promising solutions, it is seen that this algorithm has shortcomings, especially in solving high dimensional multimodal problems. In this study, the solution candidates that guide the search process in the RUN algorithm are developed using the Fitness-Distance Balance (FDB) method. Thus, using the FDB-based RUN algorithm, the global optimum value of many optimization problems will be obtained in the future. CEC 2020 which has current benchmark problems was used to test the performance of the developed FDB-RUN algorithm. 10 different unconstrained benchmark problems taken from CEC 2020 were designed by arranging them in 30/50/100 dimensions. Experimental studies were carried out using the designed benchmark problems and analyzed with Friedman and Wilcoxon statistical test methods. According to the results of the analysis, it was seen that the FDB-RUN variations showed a superior performance compared to the base algorithm (RUN) in all experimental studies. In particular, it has been shown to provide more effective results for the continuous optimization of high-dimensional problems.

Constraints imposed on the creative cover letter writing by digital online job advertisements
Authors: Ho Debbie Guan Eng , Henry Alex
Published: December 2021

Genre studies on the job cover letter (letter of application) have focused mainly on linguistic analyses of the genre in terms of the generic structure and linguistic strategies commonly used by applicants. These studies have taken the view that the cover letter was an open-ended opportunity for favourable self-promotion. However, to date no study has provided a detailed description of the context in which these letters were written. This study examines one essential contextual aspect, the job advertisement, and its impact on the cover letter. It aims to determine if the cover letter is still of major significance in the application process in the digital era. Based on a genre-based analysis of sixty Australian-based online advertisements and a case study, it is found that the open-ended and creative cover letter may no longer be the preeminent genre of the job application process.
Irish language self-efficacy beliefs: Mediators of performance and resources
Authors: Barry Shane
Published: December 2021

Self-efficacy, the system of beliefs that individuals possess which enables them to exercise control and actions when faced with a specific task, is an essential component to language learning, as it has the potential to promote the self-regulatory capacity required for successful language acquisition and performance. One way in which self-efficacy mediates language learning is exhibited in how individuals dedicate resources such as effort and time to overcoming tasks. The aim of this study was to determine the influence of Irish language self-efficacy beliefs on performance and resources allocated by Irish adults (N=450) on an Irish language reading test. Over two testing phases, three groups were formed based on results in phase one: a control group; a group of high performers; and a group of low performers. Manipulated comparative feedback and false results produced highly significant effects on performance and resources allocated, with low performing participants receiving a positive intervention consisting of false inflated results, leading to improved performance and increased time dedicated to task completion. High performers who received a negative intervention consisting of falsely deflated results saw a significant decrease in performance and the time allocated post-manipulation. The control group also saw a decrease in average performance scores, making the low performing group’s performance even more noteworthy. Overall, findings show that self-efficacy beliefs, though initially closely aligned with actual performance, can in fact be manipulated to influence performance outcomes.
Automated identification of discourse markers using NLP approach: The case of okay
Authors: Sanosi Abdulaziz , Abdalla Mohamed
Published: December 2021

This study aimed to examine the potentials of the NLP approach in detecting discourse markers (DMs), namely okay, in a transcribed spoken data. A total of 138 concordance lines were presented to human referees to judge the functions of okay in them as a DM or non-DM. After that, the researchers used a Python script written according to the POS tagging scheme of the NLTK library to set rules for identifying cases where okay is used as non-DM. The output of the script was compared to the reference human-annotated data. The results showed that the script was capable of identifying the function of okay as DM or non-DM accurately in 92% of the cases. The inaccuracy of detecting the rest was found to be caused by a lack of proper and detailed punctuation. The implications of the results are discussed, and relevant recommendations are presented by the researchers.

Team New Zealand-Sweden-Germany: A joint venture exploring language learning in digital spaces
Authors: Leier Vera , Gruber Alice
Published: December 2021

This paper reports on a study investigating the use of digital devices by language students at universities in New Zealand, Sweden and Germany. The study also examines the use of social media for learning a foreign language in an institutional context, using survey results from language students in the three countries. Based on an online survey (n=156) with foreign language learners in Sweden, Germany and New Zealand, everyday use of devices and applications by students is compared and analysed applying the digital literacies framework described by Pegrum et al., 2018. Focusing on digital tools (including devices and applications) which facilitate informal communication, we attempt to answer the research questions: “How do students interact and communicate digitally / using social networking in educational contexts and beyond?” and “How do students use online tools, devices and applications, for information retrieval and learning?” The results provide a rationale for why students’ everyday habits when using such tools should be considered in educational contexts. This exploratory study also describes how devices and applications can facilitate second language acquisition and can be used in a language education context. We recommend guidelines for teacher trainers regarding the development of digital literacies in foreign language teaching.
Emergency remote language learning: tudent perspectives of L2 learning during the COVD-19 pandemic
Authors: Dizon Gilbert , Thanyawatpokin Benjamin
Published: December 2021

As teachers and students have abruptly shifted from traditional classroombased learning to online classes due to the COVID-19 pandemic, there is a need to evaluate the attitudes of learners towards remote foreign language learning, particularly among Japanese students who often have little to no experience with the learning method. Therefore, the primary goal of this study was to evaluate Japanese L2 students’ opinions of remote language learning. Through a pre-/post-survey study design, the study also investigated if there was a significant difference between the participants’ initial perceptions of online language learning and their attitudes after a semester of study. A total of 208 students from three Japanese universities completed both the pre- and post-surveys, which were primarily comprised of Likert-scale items based on five Technology Acceptance Model constructs (perceived ease of use, perceived usefulness, attitudes towards use, anxiety, and behavioral intention). Data from reflective reports was also obtained from a select group of participants to gain a deeper understanding of the learners’ views. Pertinent findings and pedagogical implications are discussed so that language teachers can make informed decisions about their own remote teaching contexts.
Language learner attitudes, technology attitudes, and technology prevalence at the secondary level
Authors: Wesely Pamela , Plummer Elizabeth
Published: December 2021

This quantitative study explored how secondary world language (WL) learners’ attitudes about computer-assisted language learning (CALL) were related to their attitudes and self-confidence about their language class and the prevalence of computer usage in their language classroom. Research has suggested positive correlations between these factors, but it has focused on learner attitudes about specific technological tools, not on CALL as an integral, regular, consistent component of the learning process. An 81-item online survey was administered to WL learners of Spanish, French, and German in 37 US secondary schools in one Midwestern state (N = 1031). The results indicated several strong positive correlations: (1) between learner attitudes about the use of technology in their language class and learner attitudes and self-confidence about their language class, and (2) between the prevalence of computer usage in their language classroom, learner attitudes and self-confidence about their language class, and learner attitudes about the use of technology in their language class. Additionally, even a once-a-week usage of computers correlated with more positive attitudes about language class. The study thus suggests that secondary WL learners experience CALL as an integral, normalized part of the language classroom, and that the attitudinal benefits of more computer usage can be leveraged to enhance all learning.
Utilizing Flipgrid for speaking activities: A small-scale university-level EFL study
Authors: Hammett David Andrew
Published: December 2021

In 2020, the COVID-19 pandemic forced many educational institutions to implement ERT, which resulted in courses going online across Japan. Many teachers were faced with creating asynchronous or on-demand materials to meet the educational goals of their classes. The purpose of this study was to investigate the use of Flipgrid as a face-to-face speaking activity replacement. The study used four criteria based on asynchronous teaching as well as feedback from student surveys to determine Flipgrid’s efficacy as a face-to-face replacement and the use it may serve for future online or hybrid English courses. The use of Flipgrid had some observable positive and negative impacts. Students stated that motivation to learn English, as well as their listening and speaking ability grew over the first semester of the course. However, some student participants remarked that they were apprehensive to show their faces on camera for teachers and peers to see. The lack of real-time feedback from teachers may also be an obstacle to overcome for Flipgrid to be an effective replacement for face-to-face speaking activities.

Authors: Al-Saffar Mais Odai , Al-Dahhan Ziad T. , Al-taweel Rafid B.
Published: December 2021

The main objective of this study was to model the left ventricle (LV) based on 2D echocardiography imaging technique to assess the cardiac mechanics for group of patients affected by heart failure. A prospective study has been made at Ibn Al-Bitar center for cardiac surgery, for 13 patients with heart failure (HF), 9 patients were males (69%) and 4 females (31%). The mean age was 54±7 years. Those patients were supposed to undergo a CRT-D (Cardiac Resynchronization Therapy Defibrillator) implant as they didn’t respond to drug therapy. Before CRT-D implantation, 2D echocardiography was performed for all the patients, to model the left ventricle and to measure indices that were used to evaluate cardiac mechanics which are LV pressure, wall stresses, global longitudinal strain, and cardiac output. After 3-months of follow-up, 2D echocardiography was re-assessed and the left ventricular mechanics has been re-measured. Post CRT-D implantation, significant improvement in the cardiac mechanics was observed in 54% of the patients which were called responders (patients that respond to CRT-D device) and the other patients were called non-responders. It has been seen that, the circumferential wall stresses were decreased in responder’s group while increased or remain unchanged in non-responders. Global longitudinal strain for the responder’s group were increased while remain unchanged in the non-responders. So, patients were divided into responders and non-responders, based on improvement of the cardiac mechanics after 3-moths of follow up. It has been concluded that the modelling of the left ventricle based on images obtained from 2D echocardiography imaging techniques, was an important computational tool that was used to enhance understanding and support the evaluation, surgical guidance and treatment management of basic biophysics underlying cardiac mechanics.

Authors: Nofitasari Khotifatul Defi
Published: December 2021

In Islamic teachings, the issue of breastfeeding is a very important issue to pay attention to, because it can have an impact on the issue of the prohibition of marriage and lineage. The purpose of this study is to dig deeper into the urgency of breastfeeding donors and their implications based on the practice of breastfeeding donors in Indonesia, and a review of the mashlahah of these breast milk donors. This type of research is library research, with analytical descriptive method. This research uses mashlahah theory with ushul fiqh approach. As a result, breast milk donation in Indonesia can be done by fulfilling several conditions: first, the request of the biological mother or the baby’s family. Second, the identity, religion, and address of the breast milk donor are clearly known by the mother or family of the baby receiving the donor. Third, the approval of the breast milk donor by knowing the identity of the donor recipient baby. Fourth, the breast milk donor is in good health and has no medical indication. Fifth, breast milk is not traded. Meanwhile, based on Ijtihâd istishlâhî, breast milk donation which aims to help babies who do not get breast milk from their biological mothers for certain reasons, is a humanitarian aid to save human life. Therefore, it is legally permissible to donate breast milk and can be categorized as mashlahah dharuriyat if the mother of the baby is sick and the baby is premature or sick. Including mashlahah hajiyat if the baby’s mother dies, or her whereabouts are not known.

Sektor pariwisata memegang peranan penting dalam memberikan kontribusi terhadap pembangunan ekonomi negara. Salah satu bentuk pembangunan pariwisata berkelanjutan untuk mengembalikan geliat pariwisata adalah pengembangan desa wisata. Salah satu desa yang berpotensi menjadi desa wisata organik di kawasan Lombok Tengah adalah Muncan. Selain eksistensi demplot budi daya padi organik, Muncan memiliki sejumlah destinasi yang memenuhi kriteria desa wisata pada umumnya, misal: masjid kuno Sumbek yang dibangun pada tahun 1792, embung (bendungan) serta sentra kerajinan mebel yang menggerakkan roda perekonomian lokal. Kepala desa Muncan membentuk kelompok sadar wisata (Pokdarwis). Target pengabdian dalam bentuk workshop ini Pokdariws dan pemuda Karang Taruna Muncan. Tujuannya tidak lain untuk meningkatkan pemahaman serta pengetahuan Pokdarwis sebagai pengelola pariwisata dalam mengoptimalkan penggunaan media sosial sebagai alat promosi. Hasil workshop menunjukkan 15 orang bergabung menyampaikan antusiasmenya. Masalah utamanya mereka memiliki media sosial tapi belum mengetahui strategi untuk mengenalkan demplot padi organik, embung, dan daya tarik wisata lainnya melalui platform digital. Masalah kedua, kurangnya perhatian pemerintah dalam mendanai, jadi Pokdarwis tidak punya modal membuat website resmi Muncan. Di akhir workshop, peserta mempraktekkan tips dan mengaplikasikan strategi promosi digital melalui ponsel masing-masing. Workshop ini secara langsung meningkatnya kesadaran, pengetahuan dan keterampilan Pokdarwis Muncan tentang mengoptimalkan media sosial sebagai wadah promosi.

Rozeznawanie duchów.
Authors: Królikowski Wacław
Published: December 2021

Ćwiczenia duchowne św. Ignacego Loyoli i zawarte w nich Reguły rozeznania duchów wpisują się w wielowiekową tradycję Kościoła, który, opierając się na Piśmie Świętym, nieustannie otwiera się na ten dar Boży i go pogłębia. Święty Ignacy Loyola od początku swojego nawrócenia otrzymał wiele łask Ducha Świętego związanych z rozeznaniem duchów. Reguły rozeznania duchów są tego najlepszym przykładem. Autor podzielił je na dwie serie. Pierwsza seria reguł jest bardziej dedykowana osobom, które, nie mając większego doświadczenia duchowego, doświadczają wyraźnych i silnych pokus ze strony złego ducha. Druga seria reguł jest bardziej dla tych osób, które poczyniły postęp w życiu duchowym, w naśladowaniu Jezusa, i w związku z tym doświadczają pokus subtelniejszych, często pod pozorem dobra. Celem artykułu jest analiza siódmej reguły drugiej serii reguł, w której św. Ignacy opisuje działanie różnych duchów – dobrego i złego ‒ na dwóch przeciwnych do siebie drogach – drodze duchowego wzrostu i drodze duchowego regresu. Autor Reguł rozeznania duchów, czerpiąc z Objawienia, Tradycji Kościoła i osobistych przeżyć mistycznych, udziela w tej regule bezcennych wskazówek, dotyczących działania różnych duchów dla osób bardziej zaawansowanych na drodze życia duchowego.

Published: December 2021

Steels are subjected to many time-dependent degradation mechanisms when they are applied in electric power plants. They are exposed to high temperatures, multi-axial stresses, creep, fatigue, corrosion, and abrasion during such services. Used under these threatening conditions, those materials could develop various damages or failures or even form cracks. Therefore, it is desirable to prevent in-service failures, improve reliability, and extend the plant's operational life. The efficiency of the electric power plant, among other processes, depends on effective maintenance. The paper presents the evaluation of advanced procedures and knowledge in the field of steel repair welding in the maintenance of the power plants. Most repair welding of low alloy steels requires high-temperature post-weld heat treatment (PWHT), but in certain repairs, however, this is not always possible. Application of the nickel-based filler metal could also be an alternative to performing post-weld heat treatment (PWHT). The repair work expenses could be reduced if the repair is performed on-site. The novel developed repair welding procedures presented in this paper were applied for emergency weld repairing of the steel pipelines in thermal power plant, repairing without disassembling the working wheel of the coal mill in thermal power plant and "on-site" repairing turbine shaft of the hydropower plant. For all the presented repair welding procedures, weldability analysis based on the analytical equations and technological ''CTS'' and ''Y'' tests to determine the sensitivity to cold and hot crack forming were applied. Tensile tests, absorbed energies tests, banding tests, and hardness measurements were performed on trial joints, which were used to develop and verify the applied methodologies. Presented advanced weld repair technologies enable repairs for a shorter time and at lower costs compared to conventional procedures.
Pulse spray gas metal arc welding of advanced high strength S650MC automotive steel

With an increasing demand for safer and greener vehicles, mild steel and high strength steel are being replaced by much stronger advanced high strength steels of thinner gauges. However, the welding process of advanced high strength steels is not developed at the same pace. The performance of these welded automotive structural components depends largely on the external and internal quality of weldment. Gas metal arc welding (GMAW) is one of the most common methods used in the automotive industry to join car body parts of dissimilar high strength steels. It is also recognized for its versatility and speed. In this work, after a review of GMAW process and issues in welding of advanced high strength steels, a welding experiment is carried out with varying heat input by using spray and pulse-spray transfer GMAW method with filler wires of three different strength levels. The experiment results, including macro-microstructure, mechanical properties, and microhardness of weld samples, are investigated in detail. Very good weldability of S650MC is demonstrated through the weld joint efficiency > 90%; no crack in bending of weld joints, or fracture of tensile test sample within weld joint or heat affected zone (HAZ), or softening of the HAZ. Pulse spray is superior because of thinner HAZ width and finer microstructure on account of lower heat input. The impact of filler wire strength on weldability is insignificant. However, high strength filler wire (ER100SG) may be chosen as per standard welding practice of matching strength.

La utilización de imágenes satelitales se ha convertido en una herramienta de gran importancia en cuanto al análisis de dinámicas territoriales y con la existencia de varios satélites que permiten su uso de manera no comercial, se estimula la aplicación de estas imágenes en distintas áreas y campos de investigación. En el presente estudio se analizaron imágenes del Satélite Landsat 8 Sensor OLI, obtenidas del servidor web del Servicio Geológico de Estados Unidos, correspondientes a las fechas 16/6/2013, 1/2/2016 y 26/9/2021. Con la finalidad de conocer el Índice de Vegetación por Diferencia Normalizada (NDVI), para cada fecha, en ese espacio de tiempo, teniendo como objetivo la parroquia Chiguará, localizada en los Andes venezolanos del estado Mérida. Se utilizó el Software Libre QGIS Versión 3.16.4. A partir de los resultados obtenidos, corroboramos la importancia que tiene el uso de las herramientas de sensores remotos. Con respecto al índice NDVI obtenido para el área de estudio se observó, en términos generales, un avance de la vegetación densa, así como la disminución de los suelos expuestos, como datos importantes que pueden indicar la escasa presencia de actividades antrópicas en esa parroquia.

Este artículo tiene el objetivo de conocer a través de la revisión bibliográfica el nivel de transparencia en las instituciones públicas como los ayuntamientos y Comunidades Autónomas o Gobiernos regionales, por medio de la evaluación de los portales de transparencia. Para este estudio se utilizó la metodología PRISMA, basada en un trabajo teórico descriptivo de modelo documental, porque el procedimiento compromete la tarea de buscar, organizar, sistematizar y analizar una serie de artículos digitales respecto a transparencia, cuya estrategia consistió en la búsqueda en la base de datos de Scopus y Science Direct de la variable transparencia. Como resultados, se localizaron inicialmente 3371 publicaciones, luego se aplicó los criterios de exclusión e inclusión con sus razones, determinándose una nuestra de 8 artículos que ha sido la base para llevar adelante este estudio, la evaluación de dichas publicaciones ha evidenciado que las instituciones cumplen con el mandato de ley de transparencia de contar con una sede web, pero tienen un nivel de acceso a la información muy limitada y no cuentan con la información detallada y relevante para que los ciudadanos puedan conocer y hacer la valoración respecto de la gestión de sus autoridades, con la excepción del portal de transparencia Local de Galicia que es una plataforma completa, eficiente y de fácil manejo, y cuenta con el acceso a los documentos vinculados con la transparencia respecto a la publicidad activa.
Assessment of Smallholder Farmers’ Adaptive Strategies on the Effects of Seasonal Rainfall Variability on Maize Yields in Nyeri County

Maize is the leading food crop produced in most parts of the world and a staple food crop in Kenya. Majority of the maize farmers are smallholders due to reduced land sizes as a result of land fragmentation. Maize farming is rain-fed making it more vulnerable to rainfall variability. Over the years, the farmers have increased their resilience and adaptive potential through indigenous knowledge so as to cope with the climate related risks. However, the increasing rainfall variability, frequency and more severe shocks likely surpass their current adaptive strategies. The study assessed existing adaptive strategies of the small-holder maize farmers in Kieni East sub-County in Nyeri Couny to the seasonal rainfall variability effects. The research adopted a mixed research design. Data was obtained from primary and secondary sources. Primary data was obtained using household structured questionnaires. Data was analyzed using descriptive methods and presented using charts and tables. SWOT analysis analyzed several underlying aspects affecting maize farmers in the sub-County. The study found that the farmers have several specific adaptive strategies to the effects of seasonal rainfall variability at their disposal which include but not limited to the use of varieties of maize seeds, seeking training, water harvesting, use of manure and fertilizers. Farmers also respond to rainfall variability by planting maize varieties that are early maturing and drought resistant as well as engaging in alternative farming activities and other economic activities.
Inside and Outside Perspectives on the Relation of People’s Personal Values and Their Acceptance of Legal Norms
Authors: Borg Ingwer , Hermann Dieter

Based on a representative survey on crime prevention, this paper studies how personal values are related to persons’ acceptance of legal norms (LNA). We here take a closer look at these relations than previous research. Offenses, in particular, are classified into different offense types, and the persons’ ratings are studied both as observed and as individually centered data. It is found that conservation-oriented persons give higher and less differentiated badness ratings to all offenses than persons striving for hedonism and stimulation. The correlational structure of basic personal values and norm acceptance ratings for 14 different offenses, when represented via multidimensional scaling, exhibits that conservation orientation becomes a better predictor of LNA of all offense types if it is augmented by an additional value, peace of mind. When looking at centered ratings (i.e., controlling for each person’s mean ratings), social values become the best predictors of offenses such as tax evasion, benefits fraud, or taking bribes. Statements on the impact of personal values on general norm acceptance should, therefore, be replaced with more differentiated relations on how particular values are related to people’s attitudes towards particular offenses.

In many rivers of the Amazon, mainly along the Amazon River, the phenomenon of "fallen land" occurs at the time of the rivers' ebb, causing the erosion of river banks, resulting in major social and economic problems. The influence of saturation/percolation of soil layers on the shear resistance of the affected massifs is unknown. Thus, the main objective of the characterization and geotechnical modelling of these slopes is to determine the shear strength of the affected massifs. For this purpose, deformed and undeformed samples were collected from the various layers of the soil massif in a location where the phenomenon was under development. These samples were characterized physically, chemically, and mechanically. Subsequently, the massifs were recreated in reduced scale models, observing the critical conditions in which the disaster occurred, and qualitatively comparing them with slope stability computational models. The results showed that the layers are classified as silty and sandy soils, with a small fraction of clay, and that there are three types of movements associated with the fallen soils: the fall, overturning, and rotational landslide, all actively influenced by the effects of the river's ebb, saturation/percolation, and texture.
