Published: May 2023

Dalam penulisan skripsi ini, penulis membahas tentang pentingnya penggunaan media audio visual dalam menciptakan semangat belajar anak sekami. Penulis melihat bahwa banyak anak sekami  yang tidak bersemangat dalam mengikuti kegiatan sekami karena mereka merasa bosan dan tidak tertarik dengan apa yang dilihat, didengar, dan dilakukan selama proses kegiatan berlangsung. Teristimewa anak-anak  sekami  yang  berada  di  stasi-stasi  yang  terpencil  atau  jarang  ada kegiatan SEKAMI. Hal ini terlihat dari jumlah keaktifan anak sekami yang kurang aktif.

Penelitian ini dilaksanakan dengan menggunakan metode studi pustaka yang menelaah tentang teori-teori media, teori audio visual, teori semangat belajar dan SEKAMI. Penelitian ini juga memberikan usulan program yang dapat digunakan oleh para Pembina sekami dalam pembinaan menggunkan media audio visual.

Media merupakan alat bantu yang dapat digunakan seorang Pembina SEKAMI untuk menyampaikan materi pembinaan untuk anak SEKAMI. Media yang efektif dalam pembinaan iman ialah media audio visual. Media audio visual merupakan media yang memadukan unsur gambar dan suara. Penggunaan media audio visual dalam kegiatan SEKAMI dapat membantu anak SEKAMI untuk lebih mengenal peristiwa-peristiwa masa lampau dan dapat meningkatkan semangat belajar anak SEKAMI

Published: May 2023

Kepemimpinan Kristen merupakan sebuah kepemimpinan yang perlu diterpakan dengan baik dan sesuai berlandaskan Alkitabiah. Seorang pemimpin Kristen yang tidak sesuai dengan landasannya yaitu Alkitab maka tidak disebut sebagai kepemimpinan Kristen. Salah satu upaya untuk menjadikan kepemimpinan Kristen ini sebagai pemimpin Kristen yang baik dan benar adalah seorang pemimpin Kristen harus memimpin dengan berpedoman kepada para pemimpin terdahulu yang telah dituliskan di dalam Alkitab. Ada banyak para pemimpin yang baik dan disenangi oleh orang-orang yang mereka pimpin yang diceritakan di dalam Alkitab, salah satunya adalah Daud. Daud memimpin bangsa Israel pada masanya dengan baik, karena ia adalah pemimpin yang taat serta tunduk kepada Tuhan yang telah mengutus dia. Metode penelitian yang digunakan dalam tulisan ini adalah membandingkan bentuk kepemimpinan Kristen masa kini yang cenderung tidak sesuai dengan apa yang seharusnya dilakukan oleh seorang pemimpin Kristen. Oleh sebab itu, melalui tulisan ini, pemimpin di harapkan dapat menjadi pemimpin yang dapat berguna bagi manusia dan juga bagi  Tuhan. Dengan mempedomani bentuk kepemimpinan seperti Daud ini, maka akan dapat menghasilkan kepemimpinan yang baik dan menciptakan kesejahteraan di tegah umat Tuhan.

Authors: Plăcintă Domnica Daniela , Murariu Danela , Batîr Rusu Diana
Published: May 2023

The objective of this study was to evaluate the phenotypic variability of Vicia faba germplasm by using varietal diversity in identifying genotypes with morpho-productive traits, disease and pest resistance, weed infestation, which can be used as a model in the development of genetic mixtures in integrated management practices for environmentally friendly, diseases, pests and weeds. Productivity, disease and pest descriptors at 50 Vicia faba genotypes of different biological status (10 obsolete cultivars, 30 local populations, 10 inbreed lines), were determined, by testing in intercropping experiments with small grain cereals and mono-cropping, in two different climatic years under the northeastern part of Romania conditions. The statistical estimators resulting from the unidirectional Anova analysis determined in mono-cropping and intercropping systems a hierarchy of heterogeneity of local populations for productivity traits and degree of attack of faba bean weevil (Bruchus rufimanus) and ascochyta blight (Ascochyta fabae) on seeds, for incidence of micromycete Uromyces viciae fabae and of aphids Aphys fabae in intercropping system. There was a weak competition of Vicia faba species, regarding the presence of weeds compared to small grains cereals variants and potentially beneficial for nitrogen symbiotic fixation by increasing oat productivity, in two years of intercropping with faba bean. By using Euclidean distance and Pearson correlation, in classification of genotypes and morpho-productive traits, diseases and pest in clusters from dendograms, similarities were highlighted between productivity and its components and between attacks to diseases and pests and dissimilarities between genotypes, members cluster three with phenotypic variability with maximum values of productivity traits and minimum attacks to disease and pest resistance compared to the other two clusters with possibilities for use in the development of genetic mixtures programs.

Published: May 2023

The maximum crop production achievement in arid and semi-arid regions is the main issue that requires the optimum use of different variables of crop and water. Therefore, this research has been carried out for simultaneous optimization of water productivity (WP) and for high crop productivity under deficit irrigation management conditions. An original data series has been used for this research from an experimental design that was conducted in the form of randomized complete blocks design with three replications and seven irrigation treatments of different growth stages during two conductive crop seasons 2010 and 2011. The genetic algorithm has been applied as a multi-objective (MOGA) and under two scenarios of the priority of objective functions. Also, in order to investigate the application of the simulated annealing algorithm (SA), in a combined optimizing of two objective functions of soybean WP and plant production using weight summation method, it has been converted to a single objective one. The results have shown that under the first scenario conditions, the optimum grain yield and optimum WP are 3,827 and 3,953 kg ha-1 and 0.53 and 0.58 kg m-3 ha-1 in 2010 and 2011, respectively. The results in the combined optimization under the second scenario conditions show the amounts of optimum crop production and WP are 3,838.1 and 3,902.7 kg ha-1 and 1.12 and 0.75 kg m-3 ha-1 in the two seasons, respectively. Comparison of the MOGA and SA results has indicated that MOGA has a better capability in simultaneous optimization of the two objective functions. Maximum crop production was 4446 kg ha-1 for consuming 664.9 mm irrigation water. Also, the maximum WP was 0.82 kg m-3 ha-1 for consuming 375.8 mm irrigation water. Therefore, the dual-objective genetic optimization method can well optimize both objective functions and achieve the desired results in optimal grain yield and WP under constrained water resources.

Published: May 2023

Intercropping and bio-fertilizer application play important roles in sustainable agro-ecosystems. A two-year field experiment was conducted at Astaneh-ye Ashrafiyeh, Northern Iran, to evaluate the effect of Azotobacter (Azotobacter chroococcum) inoculation on the growth and yield of a peanut/maize intercropping system. The experimental design was a randomized complete block in a factorial arrangement with three replicates. Factors were Azotobacter application [control (non-inoculated) and inoculation (with Azotobacter chroococcum) and different maize (Zea mays L.)/peanut (Arachis hypogaea L.) intercropping pattern (100% peanut + 100% maize, 100% peanut + 50% maize, 50% peanut + 100% maize, 50% peanut + 50% maize, 67% peanut + 33% maize, and 33% peanut + 67% maize). Sole cropping of peanut and maize were also used. Results showed that averaged across years and intercropping patterns, grain yields of peanut and maize were significantly increased by 10% and 16%, respectively, in inoculated plots compared to non-inoculated ones. Azotobacter also had a positive significant effect on nitrogen concentration of grain, while it had no significant effect on oil concentration of peanut grain and significantly decreased the oil concentration of maize grain. Land equivalent ratio (LER) ranged from 1.05 to 1.70, indicating more efficient and productive use of environmental resources by intercrops. Results also showed that inoculated intercropped plots had 12-16% grater LER that non-inoculated ones. The highest LER was observed for inoculated plot with 100% peanut + 50% maize intercropping pattern (1.70), while the lowest one was recorded for non-inoculated plot with 50% peanut + 50% maize intercropping pattern (1.05). Based on the result of this experiment, intercropping pattern of 100% peanut + 50% maize along with Azotobacter application is recommended to obtain the highest productivity in maize/peanut intercropping system.

Published: May 2023

Gerakan seni jalanan atau street art sudah dikenal di Indonesia sejak penjajahan Belanda. Pada saat itu street art dijadikan sebagai alat propaganda untuk membangkitkan semangat berjuang rakyat Indonesia. Kemudian berkembang hingga sekarang di kalangan anak muda. Graffiti ini dianggap sebagai bentuk penyampaian ekspresi seni atau untuk menunjukkan eksistensi mereka dan komunitasnya. Selain itu graffiti termasuk seni yang tidak umum karena media yang digunakan adalah tembok. Sedangkan biasanya media untuk menggambar dan melukis yaitu kertas atau kanvas. Maka dari itu peneliti tertarik untuk meneliti apa motivasi mereka lebih memilih tembok sebagai media penyampaian ekspresi seni mereka dibandingkan dengan media konvensional liannya. Penelitian ini adalah penelitian kualitatif dan teknik pengumpulan data dengan wawancara, observasi, dan dokumentasi. Hasil dari penelitian menunjukkan bahwa motivasi mereka dalam membuat graffiti selain sebagai media ekspresi seni yaitu sebagai bentuk eksistensi mereka. Graffiti menjadi jembatan dalam proses pembentukan identitas, dengan graffiti mereka ingin dikenal oleh masyarakat. Mereka juga berusaha untuk mengubah stigma masyarakat tentang graffiti yang dianggap kegiatan illegal, merusak, dan tidak berguna.

Salinity and pH effects on survival, growth, and reproduction of quagga mussels
Authors: Seitz Carina , Scordo Facundo , Suenaga Erin , Carlson Emily M. , McMillen Shaye , Gregory Logan , Chandra Sudeep
Published: May 2023

Background

In recent decades, invasive quagga mussels have expanded to the Western United States from the Great Lakes region of North America. Most studies that evaluate the invasion potential of quagga mussels in western water bodies have utilized physiological and life history information from zebra mussels, a related taxon. Few studies have assessed the potential for invasion using specific information from quagga mussel life history or experiments that test for their survival in the fresh and saline waters of the western United States.

Methods

We investigated quagga mussel survival, growth, and reproduction using semi-natural experiments under temperature and light controlled conditions across a gradient of water salinity (fresh to brackish) and pH (8.4–11). Water from Lake Mead was used as a positive control in our experiment, and water from Pyramid Lake and the Truckee River was used as brackish and freshwater treatments, respectively. The mussels used in the experiments were collected from Lake Mead.

Results

After 12 h in brackish water (4 ppt, pH 9.3), we observed 100% mortality of adult mussels. The swelling and disintegration of body tissues and high mortality rates indicated that high potassium, sodium, and chloride concentrations were the likely causes of death in brackish water treatments. In contrast, mussels were able to survive, grow, and reach sexual maturity in freshwater (0.1 ppt) with a low calcium concentration (17 mg L−1) after 57 days. Mussels died after 2 days at pH 11 and after 12 days at pH 10; during the 14-day monitoring period, no mortality was detected at pH 9.0, 9.3, or 9.5 and mussels did not exhibit any visual indications of stress. Understanding quagga mussel physiological and environmental tolerances appears to be essential for assessing their invasion potential in aquatic habitats.

Ганзейская трофейная коллекция из городов Любека, Гамбурга и Бремена, включавшая в том числе и средневековые рукописи и документы, – сюжет сам по себе не новый как для российских, так и для немецких историков. При этом обычно его упоминания касаются перемещений либо всего трофейного груза, либо конкретных его частей. Вместе с тем некоторые рукописи из ганзейских городов, которые хранятся сейчас в отечественных библиотеках, поступили туда не через государственные каналы, а были проданы государству частными лицами. В таких случаях очевидно, что на определенном этапе бытования трофеев – еще в Германии, или уже на территории СССР, имели место некоторые несанкционированные «утечки» ценностей. Как правило, мы не знаем, при каких обстоятельствах это произошло, а знаем лишь, кто непосредственно продал рукопись в то или иное государственное учреждение. Однако, как минимум, в одном случае мы можем выдвинуть некоторые предположения, и именно этот казус и находится в центре внимания предлагаемой читателю статьи. Подобного рода кражам, вероятно, способствовало отсутствие должного учета архивного фонда, вмещавшего основную часть трофейных ганзейских рукописных материалов, практически до конца советского времени.

Статья посвящена перспективам транспорта водорода по магистральным газопроводам России. Обсуждаются особенности работы водородопроводов в мире. Проведён анализ использования на компрессорных станциях газотурбинных и электроприводных газоперекачивающих агрегатов в магистральном транспорте газа в России. Рассмотрены отличия в работе водородопроводов по сравнению с транспортом природного газа по магистральным газопроводам. Отмечено негативное влияние водорода на газовые турбины. Показано, что современное состояние газоперекачивающего оборудования на газопроводах не позволяет транспортировать водород или метановодородную смесь по существующей газотранспортной системе из России в Европу, а решить проблему можно при создании отдельной трубопроводной сети для транспорта водорода. Один из аспектов решения этой проблемы – необходимость установки на компрессорных станциях регулируемых электроприводных газоперекачивающих агрегатов.

In the era of a cashless economy, customers now emphasize banking services that are convenient, reliable and responsive. Mobile banking (m-banking) is among the latest in a series of recent mobile technological wonders. This research is aimed at investigating the effect of mobile banking service quality on customer retention among commercial banks customers in Southeast, Nigeria. The study examined the effect of reliability, responsiveness, information quality, privacy issues and system quality on customer retention. The study used an explanatory research design method using quantitative approach. The sample, consisting of 400 respondents was drawn from a cross-section of commercial banks customers with mobile banking access in Southeast Nigeria. From the 400 copies of questionnaire distributed 395 were returned valid and useful for the final analysis study used Pearson’s Correlation Coefficient to measure the relationship between mobile banking service quality and customer retention. Then regression analysis was used to estimate the cause-and-effect relationship between the variables of the mobile banking service quality and customer retention. The result showed that a positive effect for responsiveness, systems quality, and information quality on customer retention while privacy and reliability of mobile banking service quality was not significant. Among all, responsiveness, system quality and information quality have a significant effect on customer retention while reliability and privacy issues do not affect customer retention in mobile services. Therefore, to increase customer retention, the bank management should implement programs that support awareness creation, customer satisfaction, brand image and reputation by continuously assessing the service quality and delivery of mobile banking services provided to their customers, and also provide an adequate set of security components of mobile banking that protects customer’s bank details from fraud.

Authors: Kimario Rose , Mtana Noah J.
Published: May 2023

The main objective of our study was to assess the effectiveness of Task-Based Learning (TBL) in improving pupils' communicative ability in English language in public primary schools in Morogoro municipality, Tanzania. To achieve this, we utilized a mixed approach, incorporating qualitative and quantitative methods for data collection and analysis. We selected six primary schools, with a total of 320 respondents divided into an experimental group (160 respondents) and a control group (160 respondents). Data were collected through pre- and post-tests, classroom observations, and interviews with both pupil and teachers. The results of our study revealed that the experimental group, which was exposed to TBL, performed significantly better than the control group. Overall, the experimental groups consistently outperformed the control groups. Furthermore, the findings from the motivation questionnaire indicated a significant difference in motivation levels between the experimental and control groups in the post-test, suggesting that the experimental group's motivation increased significantly. Our findings have significant practical implications for teachers and policymakers in Tanzania and other countries where English is taught as a second language. Specifically, our study shows that TBL is an effective strategy for promoting communication skills in English. Also, TBL can be considered as a viable approach to enhance pupils' communicative ability and promote their motivation in language learning. Therefore, we recommend that teachers and policymakers consider adopting the TBL approach to enhance pupils' English language proficiency.

Aims: The current study aims to investigate the root canal morphology of root canals of mandibular premolar teeth via cone-beam computed tomography (CBCT) among a sample of the north Indian population.

Study Design:  Retrospective observational study.

Place and Duration of Study: Department of conservative dentistry and endodontics.

Methodology: A total of 240 CBCT images were examined in the study. The Mandibular premolars were identified, and canal configurations were classified according to vertucci classification. Root canal configurations were investigated using a chi-square test.

Results: Of the total 240 Mandibular premolars, vertucci type I was found in 86.66% in Mandibular first premolars followed by type v (8.33%) and type iv (5%). Vertucci type I was found in 96.6% in Mandibular second premolars followed by type v (1.66%), type iii (0.8%) and type viii (0.8%).

Conclusion: The root morphology of Mandibular premolars in the north Indian population demonstrated a high degree of variability. However, the clinician should be aware about the possible anatomic variations of these teeth and their relationship with the adjacent anatomic structures while planning and performing endodontic, restorative, periodontal, and surgical procedures.

Published: May 2023

Importance

Prior research suggests significant social value associated with increased longevity due to preventing and treating cancer. Other social costs associated with cancer, such as unemployment, public medical spending, and public assistance, may also be sizable.

Objective

To examine whether a cancer history is associated with receipt of disability insurance, income, employment, and medical spending.

Design, Setting, and Participants

This cross-sectional study used data from the Medical Expenditure Panel Study (MEPS) (2010-2016) for a nationally representative sample of US adults aged 50 to 79 years. Data were analyzed from December 2021 to March 2023.

Exposure

Cancer history.

Main Outcomes and Measures

The main outcomes were employment, public assistance receipt, disability, and medical expenditures. Variables for race, ethnicity, and age were used as controls. A series of multivariate regression models were used to assess the immediate and 2-year association of a cancer history with disability, income, employment, and medical spending.

Results

Of 39 439 unique MEPS respondents included in the study, 52% were female, and the mean (SD) age was 61.44 (8.32) years; 12% of respondents had a history of cancer. Individuals with a cancer history who were aged 50 to 64 years were 9.80 (95% CI, 7.35-12.25) percentage points more likely to have a work-limiting disability and were 9.08 (95% CI, 6.22-11.94) percentage points less likely to be employed compared with individuals in the same age group without a history of cancer. Nationally, cancer accounted for 505 768 fewer employed individuals in the population aged 50 to 64 years. A cancer history was also associated with an increase of $2722 (95% CI, $2131-$3313) in medical spending, $6460 (95% CI, $5254-$7667) in public medical spending, and $515 (95% CI, $337-$692) in other public assistance spending.

Conclusions and Relevance

In this cross-sectional study, a history of cancer was associated with increased likelihood of disability, higher medical spending, and decreased likelihood of employment. These findings suggest there may be gains beyond increased longevity if cancer can be detected and treated earlier.
Human phytanoyl‐CoA dioxygenase domain‐containing 1 (PHYHD1) is a putative oxygen sensor associated with RNA and carbohydrate metabolism

Human phytanoyl‐CoA dioxygenase domain‐containing 1 (PHYHD1) is a 2‐oxoglutarate (2OG)‐dependent dioxygenase implicated in Alzheimer's disease, some cancers, and immune cell functions. The substrate, kinetic and inhibitory properties, function and subcellular localization of PHYHD1 are unknown. We used recombinant expression and enzymatic, biochemical, biophysical, cellular and microscopic assays for their determination. The apparent Km values of PHYHD1 for 2OG, Fe2+ and O2 were 27, 6 and > 200 μm, respectively. PHYHD1 activity was tested in the presence of 2OG analogues, and it was found to be inhibited by succinate and fumarate but not R‐2‐hydroxyglutarate, whereas citrate acted as an allosteric activator. PHYHD1 bound mRNA, but its catalytic activity was inhibited upon interaction. PHYHD1 was found both in the nucleus and cytoplasm. Interactome analyses linked PHYHD1 to cell division and RNA metabolism, while phenotype analyses linked it to carbohydrate metabolism. Thus, PHYHD1 is a potential novel oxygen sensor regulated by mRNA and citrate.

Hydrogels are 3D scaffolds used as alternatives to in vivo models for disease modeling and delivery of cells and drugs. Existing hydrogel classifications include synthetic, recombinant, chemically defined, plant‐ or animal‐based, and tissue‐derived matrices. There is a need for materials that can support both human tissue modeling and clinically relevant applications requiring stiffness tunability. Human‐derived hydrogels are not only clinically relevant, but they also minimize the use of animal models for pre‐clinical studies. This study aims to characterize XGel, a new human‐derived hydrogel as an alternative to current murine‐derived and synthetic recombinant hydrogels that features unique physiochemical, biochemical, and biological properties that support adipocyte and bone differentiation. Rheology studies determine the viscosity, stiffness, and gelation features of XGel. Quantitative studies for quality control support consistency in the protein content between lots. Proteomics studies reveal that XGel is predominantly composed of extracellular matrix proteins, including fibrillin, collagens I–VI, and fibronectin. Electron microscopy of the hydrogel provides phenotypic characteristics in terms of porosity and fiber size. The hydrogel demonstrates biocompatibility as a coating material and as a 3D scaffold for the growth of multiple cell types. The results provide insight into the biological compatibility of this human‐derived hydrogel for tissue engineering.

Published: May 2023

Rational surface engineering of metal–organic frameworks (MOFs) provide potential opportunities to address the sluggish kinetics of oxygen evolution reaction (OER). However, the development of MOF‐based materials with low overpotentials remains a great challenge. Herein, a post‐synthesis strategy to prepare highly efficient MOF‐based pre‐electrocatalysts via all‐solid‐phase mechanochemistry is demonstrated. The surface of a Fe‐based MOF (MIL‐53) can be reconstructed and anchored with atomically dispersed Ni/Co sites. As expected, the optimized M‐NiA‐CoN exhibits a very low overpotential of 180 mV at 10 mA cm−2 and a small Tafel slope of 41 mV dec−1 in 1 m KOH electrolyte. The superior electrocatalytic OER activity is mainly due to the formation of surface FeONi/Co bonding. Furthermore, density functional theory calculations reveal that the transformation from *OH to *O is the rate‐determining step and the electrocatalytic OER activity trend at different metal sites is Co > Ni≈Fe.
Nanoliter Liquid Packaging in a Bioresorbable Microsystem by Additive Manufacturing and its Application as a Controlled Drug Delivery Device

Published: May 2023

Precise packaging of nanoliter amounts of liquid in a microsystem is important for many biomedical applications. However, existing liquid encapsulation technologies have limitations in terms of liquid waste, evaporation, trapped bubbles, and liquid degradation. In this study, multiple additive manufacturing techniques for nanoliter liquid packaging in bioresorbable microsystems is used. Two‐photon photolithography is used for bioresorbable reservoir fabrication, while inkjet printing (IJP) is used for precise nanoliter liquid packaging. Dual IJP allows for micro‐reservoirs to be filled with precise amounts of drug solution and subsequently and rapidly sealed with a layer of lipids mixed with Fe3O4 nanoparticles. Combining these two printing techniques can overcome the previous limitations of liquid encapsulation technologies. To demonstrate the relevance of this technique, a wirelessly activated, bioresorbable multi‐reservoir microcapsule that can be used for controlled drug delivery is presented. The microcapsules and their content are shown to be stable during fabrication, storage, and operation. Multiple cargo release events are triggered independently by the local melting of the sealing layer, resulting from magnetically induced Fe3O4 nanoparticle heating. The operation of the capsule is demonstrated in tissue phantoms and in vitro cell cultures.
