Evaluation of prevalence of dental erosion in swimmers in the metropolitan city of India: A cross-sectional study
Authors: Ramugade Manoj , Sapkale Kishor , Sonkurla Sapna , Sayed Abrar
Published: July 2023

Introduction: Development and research in medical sciences have increased the life expectancy of the masses resulting in the retention of more teeth in the oral cavity. This leads to the occurrence of various wasting diseases of teeth like attrition, abrasion, and erosion.
Aim and Objectives: This study evaluates the prevalence of Dental Erosion (DE) and its severity among swimmers of chlorinated pool water in a metropolitan city in India.
Material and Methods: In this study, 508 young and adult regular swimmers (including competitive swimmers) from various swimming pools were selected and examined clinically for the presence of DE. A structured questionnaire form was formulated to record the history of habitual swimming activity, diet, gastroesophageal reﬂux disease, history of intake of medications and acidic beverages, etc. for each swimmer. The data obtained were analysed and statistically evaluated.
Result: Among 508 swimmer participants, 429 were males and 79 were females. Out of these 338 (66.54%), including 293 (57.67%) male and 45 (8.8%) female swimmers showed DE. The mean age of the swimmer was 33.64 years. The majority of swimmers showed Grade I (n=260, 76.92%) type severity followed by Grade II (n=73, 21.59%) and Grade III (n=5, 1.47%). 79 (15.55%) swimmers showed teeth sensitivity. The statistical test showed a positive correlation between the duration of swimming activity and the non-use of dental protective measures with the severity of DE (P<0.05).
Conclusion: Swimmer’s erosion is mainly attributed to the acidic pH of pool water associated with chlorine amount and its severity depends upon the duration and period of swimming irrespective of the swimmer’s gender.
A comparative evaluation of microleakage among new composites FILTEK Z350 XT, TETRIC N-CREAM, and CLEARFIL AP-X: An In Vitro Study
Authors: Badkul Priya , Mahendra Muktishree , Bichpuriya Anjali , Vaidya Amruta
Published: July 2023

Introduction: Modern composites promise to improve fracture resistance, reduce postoperative sensitivity and marginal discoloration. They have also been reported to reduce microleakage, which can lead to restoration failure and tooth loss. A comparative evaluation of microleakage among newer composites FILTEK Z350 XT, TETRIC N-CREAM, and CLEARFIL AP-X was carried out to assess their efficacy in reducing marginal microleakage. Methods: The study’s samples consisted of 45 upper maxillary premolar teeth. These teeth, whose sizes varied, were removed for orthodontic reasons. Class II were prepared in teeth under aseptic conditions. The specimens were divided into three experimental groups of fifteen teeth each (n = 15) and the prepared cavities were restored with nanocomposite FILTEK Z350XT (Group-I), TETRIC N-CERAM (Group-II), and micro hybrid CLEARFIL AP-X (Group III). All the teeth were immersed in methylene blue stain to explore the microleakage. Specimens were sectioned buccolingually through the restoration using diamond disc. The restorations were assessed for presence of microleakage and examined under stereo-microscope of 40X magnification to assess the microleakage. One-way ANOVA and Unpaired student t-test analysis was carried out. Results: The mean scores of microleakage showed higher values at the gingival region for Group I and Group II, while Group III exhibited higher mean scores at the occlusal region. Further, the least microleakage was observed in TETRIC N-CERAM followed by FILTEK Z350XT followed by CLEARFIL AP-X. Conclusion: None of the composites tested completely prevented microleakage, but there were significant differences among them. TETRIC N-CERAM was the most effective material in reducing microleakage compared to FILTEK Z350XT and CLEARFIL AP-X.

تسعى الدراسة إلى الكشف عن أثر الغربة في مجموعة "متاهة كل صيف" القصصية، للكاتبة السودانية ليلى أبو العلا. وقد تجلَّت في هذه المجموعة القصصية بعضًا من الآثار الإيجابية في الغربة، وأبرزها يتمثل في: شحذ الهمَّة على الكتابة الإبداعية وتدوين المذكرات اليومية، مع ما في بلاد الغربة من مكتبات وفعاليات ثقافية تفوق ما هو موجود في بلد الكاتبة، وفيها يلتقي أبناء البلد الواحد في مناسبات دينية أو اجتماعية، ويتخلَّل اللقاءات تبادل الأحاديث عن وطنهم ومجتمعهم الذي تغرَّبوا عنه، واكتشفت الكاتبة أنَّ في بلاد الغربة جودة في بعض الخدمات الحكومية، وفي بضاعتهم، وفي الأدوية العلاجية مما يفوق ما هو موجود في البلد الأم للكاتبة، كما أنَّ التقدُّم المعرفي والثقافي بارز في البلد الذي اغتربت فيه الكاتبة – بريطانيا، ومن إيجابيات الغربة أنَّ الكاتبة تستطيع أن تُقدِّم رسالة إيجابية عن دينها، ووطنها من خلال تعاملاتها وأخلاقها مع الآخرين. كما صوَّرت الكاتبة بعض الآثار السلبية للغربة، ومنها: غياب الشعور الديني عند المغترب، والتهاون في أداء بعض الشعائر الدينية؛ لابتعاده عن أمكنتها، وفقدانه لسماعها، وكذلك: زواج بعض المغتربين من الأجنبيات وتفضيلهنَّ على بنات الوطن، أو زواج بعض المغتربات من أجانب متجاوزين بذلك الأعراف والتقاليد، كما تظهر آثار نفسية سيئة عند المغتربين أثناء وداعهم الأهل، بالإضافة إلى ما يحصل لهم من تعب أثناء إجراءات السفر، وقيود الأمتعة، ومقاعد الطيران التي لا يلتزم بها المسافرون، ثم الحالة النفسية السيئة بسبب البعد عن الأهل والوطن، والحنين والشوق إليهما، كما أوضحت القاصة بعض العادات السيئة التي يشاهدها المغترب في البلد الآخر مما يخالف عاداته وتقاليده، وثقافته الدينية، والاجتماعية.
بيعة علي لأبي بكر رضي الله عنهما "دراسة عقدية"
Authors: الغامدي صالح
Published: July 2023

هذا البحث يسلط الضوء على الأحداث التي أحاطت ببيعة أبي بكر الصديق –رضي الله عنه-بالخلافة، ويبين موقف علي بن أبي طالب-رضي الله عنه- منها، والبحث ليس مجرد سرد تاريخي لتفاصيل ذلك الحدث، وإنما هو نظرة عقدية تتوخى توضيح موقف الصحابة الكرام، ومنهم أهل بيت النبي صلى الله عليه وسلم -رضي الله عنهم أجمعين من هذا الأمر العظيم الذي التبس على الكثيرين من بعدهم؛ فخاضوا فيه بالحق أو بالباطل، كما يبرز البحث ما امتاز به الصحابة –رضي الله عنهم- من فقه وورع وحسن سياسة في تعاملهم مع الأحداث الجسام، وأن الواجب علينا عقيدة وديانة أن نحملهم في كل شؤونهم وما شجر بينهم على أحسن المحامل وأنبل الغايات، وهو اللائق بمقاماتهم الشريفة، وذلك ما تؤكده عقيدة أهل السنة والجماعة في أصل من أصولها الخاصة بمبحث الصحابة وأهل البيت رضوان الله عليهم أجمعين، وقد بين البحث أن الأرجح في أمر الخلافة أن النبي صلى الله عليه وسلم لم يوص أو ينص على أحد بعينه ليكون خليفة من بعده، ولكنه أرشد ودل الصحابة على فضل أبي بكر وأحقيته وسابقته بأقواله وأفعاله وإشاراته الظاهرة والخفية، وأن الصحابة قد أجمعوا على بيعة أبي بكر رضي الله عنه، ورجح البحث أيضًا أن عليًا رضي الله عنه لم يتأخر عن بيعة أبي بكر طمعًا في الخلافة أو أنه الأحق بها.

The Effectiveness of Media Technology Assisted Webbed Thematic Learning Model on Learning Outcomes in Social Studies, Healthy Food Theme of Students in Class V
Authors: Didisyahrir Didisyahrir , Firman  , Desyandri
Published: July 2023

Social studies learning is a lesson in people's lives that can be used as a source of social life for the benefit of learning by using social science concepts. The first reason underlying this is because of the empirical background. Students in the class are in the early age range who still see everything as a whole so that their learning still depends on concrete objects and the experiences they experience. The second reason, namely the implementation of learning in SD which is separate for each subject will result in less developing children to think holistically. The third reason is that there are problems in the early and high grades. In addition, the approach or learning method used by teachers tends to emphasize the use of the lecture method and skills in using technology that are not optimal as learning tools or media in class, thus making learning monotonous and students bored and there is still a lack of research being conducted. The aim is to determine the quality of social studies learning for fifth grade students at SDN 15 Patamuan by applying the webbed-type thematic learning model assisted by motion media technology, knowing the quality of social studies learning for fifth grade students at SDN 15 Patamuan by applying the webbed-type thematic learning model assisted by technology without using motion media and can determine the differences in the quality of social studies learning.

Published: July 2023

Community participation ensures the sustainability and success of coastal resource management (CRM) efforts. Despite this recognition, there are limited studies that assessed the factors affecting participation in CRM. There is also a need to strengthen the policies as community participation alone is insufficient. This study examined the potential participation of a coastal community in local coastal habitat restoration and coastal management efforts. Specifically, it determined the sociodemographic profile of the coastal communities, policies affecting the use of coastal resources, community perception and awareness of the policies, factors affecting participation in CRM initiatives, and strategies to protect coastal resources. Primary data were gathered through household interviews (N = 94), whereas secondary data were gathered through government agencies, online reports, and journal articles. Binary logistic regression was employed to determine the factors affecting willingness to participate. Findings revealed that there was general community awareness of regulations and positive views towards participating in CRM initiatives. Results further showed that socio-demographics, boat ownership, perceived effectivity of regulations, local government unit as a source of information, and awareness and previous participation in CRM efforts were the important predictors of participation in CRM efforts. These findings may provide strategic insights into planning and implementing more effective initiatives that promote the protection of coastal and marine resources and sustainable livelihood of the coastal resource users.

Authors: Isra Muhammad , Andrianto Dimas , Setiarto R. Haryo Bimo
Published: July 2023

Debranching is one of the enzymatic modifications of starch widely used in analyzing the increased levels of resistant starch (RS) in foodstuffs. However, this modification has a varying effect on each type of high-carbohydrate food. This study aims to analyze the effect of the debranching pullulanase modification in increasing the levels of RS and prebiotic properties of high-carbohydrate foods. This study used 28 articles that were analyzed and selected through the PRISMA guide method from 10.302 selected libraries. Secondary data will be analyzed based on the percentage of Effect Size Hedges’d (standardized mean difference/ SMD) and confidence interval (CI) values using OpenMEE software. The results showed that the pullulanase debranching enzyme method significantly increased levels of RS and prebiotic properties (SMD 2.395; CI 95% p < 0.001). In conclusion, this study confirmed that the pullulanase debranching enzyme method had a significant effect with a 95% CI in increasing the levels of RS and prebiotic properties of high-carbohydrate foods.
Chemistry Takes Center Stage: Stories and Narratives as Tools for Instruction
Authors: Reyes Ronald
Published: July 2023

Chemistry provides a constant interplay among the macroscopic, molecular, and atomistic views of matter requiring chemical educators to devise effective strategies for merging these attributes. Often, educators are challenged on how to progress towards conducive and active learning where students can see vividly through the lens of conceptual understanding. Chemistry has stories to tell; through narratives, we can convey meaning and create synchrony with the world. This viewpoint offers a glimpse into the utility of narrative thinking and storytelling as instructional tools to enable students’ conceptual understanding of chemistry. A non-exhaustive outlook on learning difficulties is given along with critical aspects of how active narration touches on human psychological perception and, thus, embeds instructions by synchronizing concepts with the world.
Unmasking the Real Effect of Gender of Household Head in Household Food Security in the Philippines
Authors: Guirindola Mildred , Custodio Carlo , Villanueva Jessica , Guirindola Ruel
Published: July 2023

The United Nations (UN) presented the 17 Sustainable Development Goals (SDGs) to be achieved by 2030 (UN 2016), and goal number two of the SDG is to end hunger and achieve food security and goal five is gender equality. The study assessed the effect of household headship on food security in the Philippines and identify significant factors and assess the gaps. The household food insecurity access scale (HFIAS) was used to evaluate household food security (n = 13,672), which was cross-examined with the households' socio-demographic and health and sanitation characteristics using descriptive and binary logistic regression analyses. From the survey, most of the households are headed by a male (84%), and only around 26% are food secure. Initially, the female-headed household had a 1.34 times higher likelihood of food security than the male-headed household, but upon considering the confounding effect and possible effect measure modification of other risk factors, male-headed households had 20% higher odds of food security. The study revealed that there was an overestimation of the magnitude of the association between food security and the gender of the household head if the confounders were not controlled. Confounding parameters that affected this result are occupation, type of cooking fuel, and type of flooring material. The gender-based gaps are mostly connected to employment; implicitly embedded are culture and income. This study adds to the body of knowledge on how the gender of the household head affects household food security as an empirical basis to refine government household food security interventions and maximize their impacts.

Published: July 2023

Taxonomy and classification of freshwater algae is highly dependent on morpho-taxonomic characterization and molecular genetic techniques. However, these methods are considered time- consuming and tedious. This study was conducted to integrate the latest technological innovations of digital image processing and machine learning in developing an automated detection, recognition, and identification of selected algal species from the divisions of Chlorophyta and Cyanobacteria. OpenCV and Tensorflow (convolutional neural networks or CNN) were used in the development of a digital image identification system of common freshwater algal species (Chlorococcum infusionum, Chlorella vulgaris, Nostoc commune, Leptolyngbya lagerheimii, Desmodesmus abundans, Acutodesmus dimorphus, Oscillatoria proboscidea, and Oscillatoria limosa). Using OpenCV, digital microalgae images were subjected to image enhancement techniques for the removal of noise and other unwanted objects that minimizes image identification errors. TensorFlow classified these pre-processed images using CNN and gives the percentage results for the algal species in which it identifies each image. The developed automated image identification system correctly identified 75 images from a total of 80 selected freshwater algae images yielding a final test accuracy of 93.75%. This study exhibited for the first time in the Philippines the use of a CNN-based automated image identification system in the recognition and classification of freshwater algae. The developed system is applicable to algal culture collections and taxonomists for fast and easy identification of algal taxa and improved storage of algal images in the database.
Morphological Characterization and Species Verification Using Cytochrome C Oxidase Subunit I (COI) of Two Laguna Populations of the Cacao Pachyrhynchine Beetle, Pachyrhynchus moniliferus Germar, 1823 (Coleoptera: Curculionidae)
Authors: Domingo Kimberly Ann , Caoili Barbara , Yap Sheryl
Published: July 2023

Pachyrhynchus moniliferus Germar is one of the major insect pests in cacao plantations in Luzon Island, Philippines. It is morphologically very similar to other Pachyrhynchus species and, thus, often mistakenly identified. Consequently, inappropriate control measures are applied. Herein, two P. moniliferus populations from Laguna province, one from Los Baños and the other from Magdalena (Philippines), were morphologically examined and DNA barcoded. The Magdalena population has a bigger body size, as well as a longer and wider rostrum compared to the Los Baños population. Comparison between the Folmer fragment of the COI gene of the Pachyrhynchus from Los Baños and Magdalena to the nucleotide sequences in the GenBank revealed a best match of only 87% identity to P. speciosus Waterhouse (KU953498.1) and 88% to P. orbifer Waterhouse (KU953440.1), respectively. The COI sequence of P. moniliferus presented here is the first DNA barcode reported for this species (GenBank Accession Numbers: MT038197.2–MT038204.2). We recommend conducting more thorough morphometric studies in conjunction with genetic diversity analyses on the different P. moniliferus populations across the Philippine islands.

Reactive oxygen and nitrogen species (ROS/RNS) are known to cause oxidative damage to cells and macromolecules. Intake of antioxidant-rich fruits and vegetables has been touted as a strategy to mitigate oxidative stress, but this is not always accommodated in modern diets. Augmentation with antioxidant-rich herbal supplements may be a preventive measure against the negative effects of ROS/RNS. In this study, we verify and compare the antioxidant claims of herbal supplements by measuring their phytochemical content and antioxidant capacities through the oxygen radical absorption capacity–multi-radical (ORAC MR5) assays. ORAC MR5 measures antioxidant activity against five biologically relevant ROS/RNS (peroxyl and hydroxyl radical, superoxide anion, singlet oxygen, and peroxynitrite). Four products were tested: two multi-herbal capsules (INT and Oxxy), a mangosteen fruit pulp powder capsule (MPC), and a mixed herbal drink (MHD). Phytochemical content was quantified through total phenolic and flavonoid content assays. Oxxy had the highest flavonoid content per serving (106.4 mg catechin eq/ 450 mg capsule) and ORAC MR5 value (37,503 μmol Trolox eq/ 450 mg capsule), followed by INT (53.5 mg catechin eq and 17,298 μmol Trolox eq/ 200 mg capsule), MPC (48.1 mg catechin eq and 7,675 μmol Trolox eq/ 500 mg capsule), and then MHD (7.4 mg catechin eq and 146.7 μmol Trolox eq/ 30 mL drink). Significant antioxidant activities against peroxyl radicals and singlet oxygen were observed for INT and Oxxy, whereas the antioxidant activity of MPC and MHD were mostly towards peroxyl radicals. A strong correlation was found between phenolic and flavonoid contents and ORAC MR5 values, and we confirmed supplier claims on standardized phenolic content or antioxidant activity of INT and Oxxy. This study demonstrated the utility of ORAC MR5 as a measure of in vitro antioxidant activity of herbal supplements against biologically relevant ROS/RNS and may be used for the development and quality control of herbal supplements.

Small-scale fishers belong to the most vulnerable communities in developing countries. In the Philippines, small-scale fishers are among those with the highest poverty incidence. In Davao Region, the livelihoods of small-scale fishers can be seriously affected by constraints in fish catch, impacts of climate change, as well as the implementation of closed season ordinance. With this background, this study explores the potential of tourism on Samal Island as a source of supplemental income for fisherfolks. Specifically, this study aims to identify the factors that affect the willingness of fisherfolks to engage in tourism-related activities. Descriptive analysis and logit regression were utilized to analyze the data gathered from 100 fisherfolks. Results show that the majority of the respondents are willing to participate in tourism-related activities. Married fisherfolks and those with higher household incomes are more likely to participate in tourism-related activities. These results present opportunities for the tourism industry to employ workers from the fisheries sector. Results also reveal that participation in tourism-related activities is seen by fisherfolks as a potential source of supplemental income rather than a source of alternative income. Fisherfolks who are not willing to participate in tourism activities lack experience and interest in tourism, being used to fishing as the only source of livelihood, or have other sources of income. The local government unit is recommended to assess the training needs of fisherfolks and capacitate them to engage in tourism- related activities. This research provides significant findings from the perspective of the fisherfolks. Future studies can consider assessing community participation in general, which includes women, household members, and other community members. It is also recommended to conduct a study from the perspective of business owners in the tourism industry.

Acute oral toxicity test of "bignay" ‘common’ [Antidesma bunius (Linn.) Spreng cv. ‘Common’] fruit extract (BCFE) was conducted in male and female ICR mice following the OECD Guidelines 425 (2008) to evaluate its safety profile. Irrespective of the sex, physiological [body weight (BW) and BW gain; feed and water intake], hematological [total and differential white blood cell (WBC) and red blood cell (RBC) counts], and biochemical [creatinine and blood urea nitrogen (BUN) levels] parameters were generally unaffected except for the observed decrease in BW and increase in BUN in female mice treated with 2000 and 175 mg/kg BCFE, respectively. In addition, only slight alterations in absolute WBC counts were accounted in BCFE-treated female mice given 55, 175, and 2000 mg/kg doses, as well as in treated male mice administrated with 550 mg/kg BCFE, as opposed to their corresponding controls. Corroborating the absence of mortality, no overt signs of treatment-related toxicity were noted upon gross, biometric, and histological assessment of major organs including the gastrointestinal tract, lungs, liver, kidneys, spleen, heart, and brain. Taken together, the cumulated findings of the present study suggest that oral supplementation of BCFE is relatively safe for consumption up to 5000 mg/ kg in treated ICR mice.

Sponge-microbe symbiosis is considered among the most primitive ecological relationships between metazoans and microorganisms. There is strong interest in understanding the occurrence of microbial communities in sponges due to their integral roles in host ecology, nutrient cycling, and production of potential bioactive secondary metabolites. However, most studies on sponges have been centered on marine species. In this study, the freshwater sponge Spongilla alba and its associated microorganisms were explored for the first time. Sponge samples collected from Lake Taal were taxonomically identified using gross morphology and spicules analysis. Both bacterial and fungal isolates were culturally characterized and molecularly identified using 16S rRNA gene for bacteria and ITS for fungi. Five bacterial species were identified as Pseudomonas sp., Enterococcus sp., Stenotrophomonas sp., Stenotrophomonas maltophilia, and Pseudomonas mosselii plus eight fungal species with spore sizes from 5–10 μm were identified as Colletotrichum truncatum, Trichosporon asahii, Rhizopus microsporus, Puccinia striiformis f. sp. tritici strain, Talaromyces columbinus, Phoma sp., Phomopsis sp., and Lichtheimia ramosa. Phylogenetic analysis revealed microbial sequences belonging to Proteobacteria (n = 4), Firmicutes (n = 1), Ascomycota (n = 4), Zygomycota (n = 2), and Basidiomycota (n = 2). The study reports infrequent occurrences of Enterococcus, Stenotrophomonas, Puccinia, and Lichtheimia species as freshwater sponge-associated microbes. This also presents the culturable microbial composition of freshwater sponges and rare occurrence of marine- and terrestrial-associated fungi T. asahii, R. microsporus, Phoma sp., Phomopsis sp., C. truncatum, and T. columbinus in a unique freshwater ecosystem such as Lake Taal.

Two of the most studied Etlingera species of the ginger family (Zingiberaceae) in the Philippines were Etlingera fimbriobracteata (K.Schum.) R.M.Sm. and E. philippinensis (Ridl.) R.M.Sm. However, little is known about the biochemical analyses of these species to support their potential as ethnomedicinal plants in the country. Thus, this study was carried out to describe the morphology and determine the phenolic content and antioxidant activity of the ethanolic extracts of the two Etlingera species. Data revealed that the two species are correctly identified and their full description, updated distribution, phenology, and habitat and ecology are provided in this paper. The two species are recognizable in both vegetative and reproductive parts. E. fimbriobracteata has reddish color towards the base of the pseudo stem, bright yellow flowers incurved upon maturity, and green sterile bracts that form reddish upon maturity, whereas E. philippinensis has mandarin to deep red inflorescence and has a long outward labellum. The total phenolic content (TPC) expressed as milligram gallic acid equivalent per gram dried sample (mg GAE/g dried sample) revealed the highest phenolics in the leaves (13.20 ± 0.35 in E. fimbriobracteata and 7.21 ± 0.33 in E. philippinensis) than rhizomes (1.44 ± 0.04 in E. fimbriobracteata and 0.46 ± 0.30 in E. philippinensis). Further, total antioxidant activity (TAA) expressed as milligram ascorbic acid equivalent per gram dried sample (mg AAE/g dried sample) was also observed highest in leaves (12.69 ± 0.36 in E. fimbriobracteata and 7.22 ± 0.26 in E. philippinensis) compared to the rhizomes (1.82 ± 0.01 in E. fimbriobracteata and 1.38 ± 0.07 in E. philippinensis). The reducing power (RP) expressed as milligram gallic RP equivalent per gram dried sample (mg GPRE/g dried sample) also revealed higher for the leaves (10.16 ± 2.18 in E. fimbriobracteata and 7.53 ± 0.80 in E. philippinensis) than rhizomes (0.97 ± 0.18 in E. fimbriobracteata and 0.09 ± 0.09 in E. philippinensis). The high contents of phenolic compounds contribute to the antioxidant activity of extracts from the two species. Based on the correlationanalysis, a perfect positive linear relationship was observed among the TPC, TAA, and RP (r= 1, p < 0.001). These imply that E. fimbriobracteata and E. philippinensis could potentially beused as new sources of natural antioxidants.
Notes on the Nest Architecture and Nest Site Characteristics of Mindanao Treeshrew (Tupaia everetti Thomas, 1892) from Dinagat Islands, Philippines
Authors: Senarillos Tristan Luap , Ibañez Jayson
Published: July 2023

The Mindanao treeshrew (Tupaia everetti Thomas, 1892) is an endemic non-volant mammal species found in the Mindanao Faunal Region in the Philippines. The nest architecture and nest site characteristics of T. everetti are described for the first time based on a single active nest documented from Dinagat Islands. The nest was on the ground, built inside a cavity of a dead pandan tree (Sararanga cf. philippinensis), and was surrounded by natural vegetation. This nest discovery is a valuable contribution to the minimal existing literature about this poorly studied species, which may be increasingly threatened by anthropogenic impacts. As such, we highly recommend more nest search and breeding ecology studies on Dinagat islands and other areas where T. everetti is found to determine if the nesting pattern is similar to what was discovered in this study.
Effects of Arbuscular Mycorrhizal Fungi on Rice (Oryza sativa L.) Grain Yield: a Meta-analysis Using Different Sources of Variation
Authors: Java Ched Justin , Paguntalan Diana , Abacan Elfred John
Published: July 2023

The increase in annual rice (Oryza sativa L.) grain yield is attributed to chemical and inorganic fertilizer utilization. However, these types of fertilizers reduce grain quality in the long term. Arbuscular mycorrhizal fungi (AMF) can act as biofertilizers and improve crop performance. The present study conducted a meta-analysis on the effects of AMF on rice grain yield using the studies conducted in selected countries in Asia. Ten (10) studies were selected, and 59 experimental results were used. The overall result showed that AMF positively affects the rice grain yield. The AMF experiments on the field and greenhouse showed positive effects, as well as across different environmental conditions, including aerobic and nutrient addition. The multiple-species type of AMF biofertilizer and the single-species type under different genera – namely, Acaulospora and Glomus – also showed a positive effect. The effect of AMF on different rice varieties is also positive, especially on varieties grown in lowland agroecosystems. The findings in this study show that various types of AMF increase the rice grain yield of different rice varieties under various environmental conditions. This supports the application of AMF in rice farming.

Authors: Lawati Susi
Published: July 2023

This research focuses on the turnover rate of CV Piramida Jaya Bandung which varies from 2019 to 2022. However, this research also intends to understand organizational commitment, work motivation, turnover intention, and the extent to which organizational commitment and work motivation influence simultaneously and partially. employee turnover at CV Pyramid Jaya. This study uses a quantitative research design with descriptive and verification methodologies, with data collection through questionnaires, interviews, observations, and literature studies. The study population was all employees of CV Piramida Jaya, totaling 60 people, with a saturation sample which incidentally could represent all employees. Organizational commitment (X1) and work motivation (X2) are independent variables, and turnover intention (Y) is the dependent variable. Validity, reliability, and traditional assumption tests are part of data analysis. Data processing using statistical product and service solution software includes data analysis methods linear regression analysis, correlation, determination, T test, and F. Thus it is hoped that this research can explain the variables that influence CV Piramida Jaya employees' intentions to leave their jobs and offers useful advice for human resource management. According to the results of the questionnaires filled out by respondents, the main cause of employee intention to leave the company is a lack of commitment which is revealed through poor training and lack of employee attendance because it does not support careers and employees. development. Regression analysis and other appropriate statistical methods will be used to analyze the data to determine the impact of organizational commitment and work motivation on turnover intention. Also anticipated from the study findings are ideas or recommendations to improve CV Piramida Jaya's human resource management and better knowledge about the factors that affect the turnover rate in the company.
