Authors: Jemaica C. Mueda  , Elvira E. Ongy
Published: November 2023

It is undeniable that the demand for locally processed root crops is low compared to commercial junk foods, affecting the income of both farmers and local processors. This study was conducted to ascertain the product attributes that influenced the purchasing decision of the consumers which serves as a basis for positioning the product in the market. It utilized a survey research design using a combined purposive and quota sampling techniques to select the respondents who are the target market of the product. This study collected market data and consumer preferences from 200 segmented respondents who are located in Baybay City, Leyte. Conjoint analysis was used to determine the attributes that highly influenced the buying decision of the consumers. Results show that product type highly influenced the buying decision of the consumers. Processed root crops that are locally produced are mostly preferred by the consumers over commercial junk foods. However, consumers are rarely buying the product because it is unavailable in the common market outlets. Given its high market potential, it is recommended to modify and improve the marketing strategies employed by the local processors. Tapping LGUs for promotion and other aid for complying with the regulatory requirements necessary for placing the product in the local and department stores is highly advised.

Compatibility of Computer-based Learning with Differentiated Learning Styles of Chemical Engineering Students as Evidenced by the Outcomes
Authors: Evelyn A. Cardoso
Published: November 2023

The incorporation of more computer-based courses and teaching-learning strategies in the Chemical Engineering (CHE) curriculum prompted educators to use information technology more effectively and efficiently. Thus, this research investigated the compatibility of Computer-Based Learning (CBL) with the learning styles of the CHE students through their learning outcomes. With a quasi-experimental research design, the researcher employed a CBL instrument structured in four steps (see-try-do-explain) and assessed the learning style preferences using the Felder-Solomon Index of learning style. The respondents included all fourth-year students enrolled in the Computer Applications in Chemical Engineering. The study revealed that CHE students are mostly sensing and visual; they found it hardest to transition from step ‘see’ to step ‘try’. Verbal and global learners will most likely survive in the four-step CBL while active learners will lag. However, the research failed to show that CBL was significantly compatible with the differentiated learning styles of the CHE students.

Authors: Geraldine B. Mangmang
Published: November 2023

Grade inquiry with short messaging service is a way to improve the mode of inquiring information. This study aimed to develop and implement a grade inquiry system using short messaging services. The study was conducted through a developmental-evaluative design. The performance of the existing and the developed system were compared based on the effectiveness, satisfaction, functional suitability and security. This comparison was assumed based on a metrics of quality of use model (i.e., effectiveness, satisfaction) and product quality model (i.e., functional suitability, security), according to the ISO/IEC 205010:2011 standard. The software was developed in a Microsoft Visual Studio 2012 application and Microsoft SQL Server 2005 database system which permits students to use the Smart and Globe telecommunication networks. This system allows students to inquire of their grades through Short Message Service (SMS) using a code, ID number, and password through their mobile phones. Proportionate sampling was applied to the graduate students who served as respondents, to gather the needed data. Wilcoxon Matched Pairs Signed-Rank Test was used to determine the significant difference between the existing and developed system. Results showed that the developed system was very effective and the students very satisfied. However, there was no significant difference regarding to functional suitability between the existing and developed system. Modernized inovation that will focus on the design and the use of computer technology pertaining to grade inquiry should be developed, to cater to students’ grade inquiries. These outcomes will help the university in fulfilling the needs of the students and their expectations.

Boosting Problem Solving Skills Through Situated-Cognition Teaching: An Analysis Based on Polya’s Framework
Authors: Juanita M. Costillas
Published: November 2023

This study compared the level of mathematical problem solving skills of students exposed and not exposed to the situated-cognition teaching model. It used Non-Equivalent Control Group Design with two intact classes of first year engineering students conducted in a regular schedule of the same time slot and room; taught by the researcher. The contents included problems in Arithmetic, Advanced Algebra and Trigonometry using Semantic Differential Scale for Content Validation of the Pretest/Posttest and Formative Tests. Within the framework and delimitations of the study, the situated-cognition teaching model posted significantly better mathematical problem solving skills (p-value=0.023<0.05) than the conventional teaching model. This supported the theory of Choi and Hanaffin (1995) which underscores the importance of providing a more realistic way of conceptualizing a particular situation for the students to become better problem solvers. It is recommended that situated-cognition be used as a teaching model for enhancing the problem solving skills of the students, or used to complement the conventional model.
Penetration and Diffusion of Functional Literacy in a Digital Society
Authors: Erlinda D. Tibus
Published: November 2023

In any context, it is necessary to be functionally literate to successfully and efficiently perform as a citizen of the country. This research used the Bass Diffusion Model (Bass, 1969) to establish diffusion in terms of functional literacy in Southeast Asian nations, the number of years a state achieves the highest level of adoption, the fraction of the population that adopts functional literacy, and the varying reasons for adoption of the phenomenon. Countries like Malaysia and Thailand will achieve their peak of adoption sooner except Vietnam. Among the 10 countries in Southeast Asia, Thailand was ranked first and Malaysia ranked second with the least number of years to reach the peak of adoption, while Vietnam is seen to have the highest number of years to reach its peak of adoption. The remaining countries will settle for 40 to 65 years. Furthermore, the varying percentages of the population reaching the peak of adoption are ascribed to the distinctive characteristics of the education system that nations have. In a conclusion, functional literacy has a beneficial effect in Southeast Asian nations and its diffusion is determined by the distinctive and systematic variations in their educational reforms. Besides, cultural and economic differences are also key variables to be regarded when predicting the spread of functional literacy in Southeast Asia. As this research only attempted to predict diffusion in terms of functional literacy, this requires further validation.
Eliciting and Sustaining Critical Thinking Through Brain-Based Teaching In Mathematics
Authors: Juanita M. Costillas
Published: November 2023

Brain-based teaching (BBT) was applied to determine if it elicits and/or sustains critical thinking while learning Mathematics. This study uses secondary data from the quasi-experiment of Vallinas (2015) conducted to 30 Grade 6 students whose permit of use was obtained prior to further analysis. In the experiment, teaching and learning process was based on the three basic fundamentals of BBT, namely, relaxed alertness, orchestrated immersion, and active processing. The last phase includes the “questioning and deep thinking”, “asking question as the basic condition required to think”, and “giving of meaning to a question”. Active participation of the teacher signifies the important component of BBT; hence, considered in making the 30 lesson plans used in the entire study. Eliciting skills were based on the scores in the 20-item probing questions while sustaining skills were based on the 10-item implication questions given after BBT. These questions were revisions of those provided in the lesson Guide for Elementary Mathematics of the Department of Education. Results reveal that females are motivated (elicited) to think critically more than females but both can sustain (keep on track) it once elicited already. Meanwhile, left-handed students likely elicited and kept on tract towards critical thinking in the same trend with the right handed one. Thus, BBT tends to create opportunity for both male and female or right-handed or left-handed students to enhance critical thinking once elicited and then sustained.

Global Gender Gap on Suicide: Why are Men More at Risk?
Authors: Adel Grace P. Gaudicos  , Bevic M. Barsolaso
Published: November 2023

The present study investigates the gender difference in suicidal behavior using principal component analysis (PCA). A huge database was retrieved globally for increased validity and effect. Additionally, regression relationship for estimating the suicidal rate of men, based on the selected factors from the PCA, was developed. The PCA showed three components of vital factors that explains 79.9% of the variation of all variables. The study used male and female suicide rate, HIV/AIDs prevalence, tertiary enrolment, democracy, professional psychiatrist, GDP per capita and unemployment indices across countries as of 2015. The evidence suggests that unemployment and spread of sexually transmitted infections (STIs) are not the root cause of why men are more likely to commit suicide. It is also clear that national revenue and the reluctance of men to psychiatric intervention are the causes of the higher suicide rate. However, the study revealed that openness to psychiatric intervention would significantly affect the male to female suicide ratio. An increasing openness to psychiatric intervention would decrease the suicide rate of men.
Do Not Resuscitate Orders for Adults with Developmental Disabilities: Ethical Considerations in the Dialysis Center
Authors: Sledge, LCSW Renata
Published: November 2023

Each discipline in the nephrology community has a specific code of ethics with clearly defined principles, values, and standards of practice. Reconciling these often similar values and principles with differences in professional language (jargon) and perspectives is a challenge experienced by all members of the interdisciplinary team. The following is a brief discussion of four principles of medical ethics defined by Beauchamp and Childress (1994) and the relationship of these principles to those in the National Association of Social Workers (NASW) Code of Ethics (2008). A model for resolving ethical conflicts is described and a case study using the model is presented.

Published: November 2023

Live donor kidney transplantation is the best treatment for eligible people with end-stage renal disease. Unfortunately, living kidney donation rates have declined in the U.S. in recent years. To better understand this phenomenon, to identify opportunities to increase donation rates, and to promote best practices in live donor care, the American Society of Transplantation’s Live Donor Community of Practice, with the support of 11 societies, convened the Consensus Conference on Best Practices in Live Kidney Donation in June 2014. The workgroup focused on reducing financial and systemic barriers to live donation, and had a multi-layered task: to review literature assessing the financial impact of living donation; to analyze employment and insurance factors; to learn from international models to reduce financial impact; and to summarize currently available resources. The group provided a series of clinical, programmatic, and policy recommendations to reduce financial and systemic barriers, with the overall goal of achieving financial neutrality for living kidney donations (LKD). In this article, we highlight systems-wide recommendations that would benefit from advocacy by nephrology social workers and their colleagues, and would ultimately improve clinical practice: policies to allocate resources to reduce donor financial burden, civil protections for donors, and a standardized, centralized financial resources clearinghouse.

Published: November 2023

Social support is associated with adherence to medical treatments (Chisholm-Burns, Spivey, & Wilks, 2010). This is the first study to explore social support and adherence 6 weeks post-kidney transplant. Fifty-eight adult deceased-donor kidney transplant recipients participated in the study. Social support was assessed using the Modified Social Support Survey; adherence was defined as the proportion of appointments kept, immunosuppressant blood values, and the Immunotherapy Barrier Scale. Measures were completed at transplant, and at 2, 4, and 6 weeks post-transplant. Data were analyzed using linear mixed models with random effects for person. Variance in participants’ adherence was hypothesized. However, all participants were adherent; no statistically significant relationship between adherence and social support was identified. Immediately following transplant, qualitative or mixed-method approaches may give better insight into facilitators of adherence.

Authors: Anderson, DSW, LCSW Elizabeth , St. Charles, LCSW-A, MSW Nicole , Lupu, PhD, MPH Dale
Published: November 2023

Despite efforts to increase supportive care for patients on dialysis, many barriers continue to exist. This study surveyed dialysis facilitystaff to examine the barriers and facilitators related to providing supportive care to patients on dialysis. This qualitative analysis revealed five barriers: 1) lack of integrated, holistic teams; 2) practitioner beliefs; 3) perceptions of social work competence; 4) time andworkload; and 5) lack of clarity regarding palliative care versus hospice and interpreting Medicare benefits. The analysis also revealed four facilitators related to providing supportive care: 1) integrated, holistic teams, including family involvement; 2) collaboration acrosscare teams; 3) communication and compassion; and 4) formal or regular mechanisms for the review of advance-care plans. Based onthe professional ethics code, social workers can play a role in bolstering their own teams’ capacity to integrate supportive-care practices. Further, using their advocacy skills, social workers can lead efforts to ensure that they and their colleagues have appropriate training and competence in supportive care. Finally, social workers, with their knowledge of community resources, can help foster innovative collaboration between dialysis organizations and palliative care and hospice organizations, in spite of current regulatory and financial barriers.

Authors: Breckenridge, LICSW, DSW Tiffany
Published: November 2023

In the healthcare field, there has been increased recognition of the long-term consequences that adverse childhood experiences (ACEs) have on the health and well-being of people. It is imperative that a trauma-informed care (TIC) approach is utilized in the treatment of patients with end-stage kidney disease (ESKD) because of high rates of non-adherence and health risk behaviors. The purpose of this article is to explore current nephrology practices and TIC approaches utilized in the healthcare field. A TIC approach, through a health-belief model lens specific to the ESKD population, can be introduced by providers to better assess and treat patients. Implications for practice include standardization of TIC in social work practice, better outcomes for patients, and ongoing research considerations.

Published: November 2023

Pacelties spārnos, pārvarot Zemes pievilkšanās spēku, un lidot ir bijis sens cilvēku sapnis, kas īstenojās 20. gadsimta pirmajā desmitgadē, pateicoties dažu Eiropas un ASV konstruktoru projektiem un praktiskiem eksperimentiem. 1911. gada sākumā vairāku tūkstošu pilotu, tostarp lidmašīnu konstruktoru, darbība piesaistīja ne tikai plašu sabiedrības uzmanību, bet arī militāro iestāžu interesi. Rakstā analizēti nozīmīgi dati par 13 369 konstruktoriem un pilotiem no 51 pasaules valsts no 1900. līdz 1914. gadam – valsts piederība, militārais rangs, sertifikācijas datums un vieta, lidmašīnu ekspluatācijas vieta, iekšzemes un ārvalstu lidmašīnu tipi, bojā gājušo skaits utt. Šai grupai pievienoti helikopteru, ornitopteru, planieru un citu lidojošo aparātu konstruktori, apzinot 14 142 personu datus.

Flight heavier-than air, despite speculations long back in history, made its breakthrough during the first decade of the 20th century, based on the designs and practical experiments of at first a handful of constructors in Europe and the United States. Already by early 1911, the activities of several thousand aviators, constructors of airplanes included, attracted not only wide public attention but also the interest of military establishments. The article analyzes significant data – nationality, profession, military rank, date and location of certification, location of airplane operations, domestic and foreign airplane types, and fatalities – for 13 369 constructors and aviators from 51 countries worldwide and active between 1900 and 1914. Added to this group are the constructors of helicopters, ornithopters, gliders and other f lying apparatus, resulting in a total of 14 142 individuals.
National Responses to Great Uncertainty in EU Authorisation of Pesticides and Industrial Chemicals
Authors: de Braal Wilke
Published: November 2023

This article looks into how two sectoral regulatory systems – EU legislation applying to pesticides, and EU legislation applying to industrial chemicals – accommodate national participation in decisions about uncertain risks. It identifies uncertainty as situations in which
the probabilities or other important information needed for a well-informed decision are lacking, and therefore refers to these situations as 'great uncertainty'. The article explores the assumption that national participation in decision-making under great uncertainty leads to higher environmental
protection compared to centralised decisions. It does so by addressing the role of EU Member States and their national competent authorities in marketing authorisation decisions on pesticides and industrial chemicals, the exercise of national discretion in the authorisation of these substances,
and the use of temporary derogation clauses by Member States once a product has been allowed to enter the market. The article compares two regulatory fields, as the two main harmonisation measures in this field – the Plant Protection Products Regulation and REACH – have established
different authorisation systems: a decentralised system in the case of pesticides and a centralised system in the case of industrial chemicals. The outcomes of this comparison are that both systems enable national decisions about uncertain risks, but that the identified examples of national
participation are not necessarily a response to great uncertainty.

Authors: Kiologwe Angel Ezekiel , Kisawike Blandina , Ng’elenge Haji
Published: November 2023

This study examines the relationships between crowdsourcing, ideation, and business plan competitions to evaluate the effect of innovation spaces on early-stage enterprises' performance. One hundred fifty participants were chosen for the study via convenience sampling from hubs in Iringa like SIDO TLED Hub, RLabs, Kiota Hub, and Agriedo Hub. Three goals were pursued: determining the impact of crowdsourcing on performance, examining the influence of ideation, and evaluating the contribution of business plan competitions. Factor analysis evaluated validity, while Cronbach's Alpha verified dependability. Both multiple regression analysis and Pearson correlation were used to analyze the data. Results reveal that ideation, crowdsourcing, business plan competition, and performance correlate positively. Recommendations: Early-stage companies should partner with spaces for resources and growth; innovation spaces should improve processes and support enterprises.

Two‐dimensional (2D) transition metal dichalcogenides (TMDs) have garnered significant attention in gas‐sensing applications due to their sensitive response to a wide range of gas molecules and their ability to operate at low temperatures, resulting in low‐power consumption. However, there are several areas that require improvement, including insufficient sensitivity at low detection limits, limited gas selectivity, low reliability, and poor recovery. To address these issues and enhance the performance of gas sensors, researchers have proposed the functionalization and hybridization of 2D TMDs. This review paper focuses on elucidating the synergistic effects of functionalization and hybridization of 2D TMDs with carbon‐related materials, metals, MOs, and metal chalcogenides. The paper presents an in‐depth analysis of the mechanisms involved in enhancing the performance of 2D TMD gas sensors and explores various synthesis methods for achieving functionalization and hybridization. Furthermore, the challenges currently faced in the field are discussed and offer insights into the future prospects of TMD nanocomposite‐based gas sensors. By comprehensively addressing these aspects, this research aims to contribute to the advancement of gas‐sensing technology using TMD nanocomposites.

For the first time, low‐pressure nitrocarburizing process is performed in a minorly modified standard vacuum furnace on 16MnCr5 alloy steel samples. Ammonia and acetylene are used as a source of nitrogen and carbon, respectively. Lowering the pressure of the process ensures longer and more efficient ammonia dissociation. To prove the safety of the process, exhaust gases are investigated online using residual gas analyzer mass spectrometer, whereas reaction products deposited on the sample's surface are studied by means of time‐of‐flight secondary ion mass spectrometer. Possible reactions taking place in the atmosphere of the chamber are written down. In the results of conducted examinations, it is confirmed that no toxic gases are generated, and no cyanides and polycyclic aromatic hydrocarbons are formed during the process. Additionally, microstructure analysis of the cross sections of nitrocarburized sample is performed using scanning electron microscopy (SEM) and optical microscopy. It confirms the diffusion of nitrogen and carbon into the near surface layer. SEM/energy‐dispersive X‐ray spectroscopy analysis demonstrates precipitation of carbide and carbonitride, what is proved by X‐ray diffractometer and microhardness profile analysis. The presented low‐pressure nitrocarburizing results in an increase in hardness from about 200 to over 500 HV and the formation of an effective case depth of about 20 μm, after only 20 min of the process.

Zinc (Zn)‐based materials reveal inadequate mechanical properties as orthopedic biodegradable implantable materials, which limits their biomedical applications. Herein, Zn–xMg (magnesium) composites (x = 0.5, 1.0, 1.5, and 2.0 wt%) reinforced with 0.2 wt% graphene nanoplatelets (GNP) are obtained via powder metallurgy and hot‐pressing sintering. The addition of 0.5–2.0 wt% Mg into Zn–0.2 wt% GNP composite resulted in the formation of Mg2Zn11 and MgZn2 phases without any additional intermetallic carbide phases. The hot‐pressing sintered (HPS) Zn–0.5Mg–0.2GNP composite exhibits a compressive yield strength of 169 ± 18 MPa, an ultimate compressive strength of 270 ± 39 MPa, a compressive strain of 17 ± 6%, and a microhardness of 86 ± 2 HV. Electrochemical corrosion testing reveals that corrosion resistance of HPS Zn–xMg–0.2GNP composites decreases with increasing Mg content, while immersion tests in Hanks’ balanced salt solution for 30 d indicate that the degradation rate increases from 0.032 to 0.141 mm y−1 by increasing Mg content from 0 to 2.0 wt%. In vitro cytotoxicity assessments using SaOS2 human osteoblast cells show >90% viability following exposure over 5 d to 12.5% extract concentrations of all HPS composites. The HPS Zn–0.5Mg–0.2GNP composite exhibits the appropriate material properties for biodegradable bone‐implant applications.

Due to their outstanding electrical conductivity, simplicity of synthesis, and exceptional flexibility, conductive polymers are the most attractive electrode materials for micro‐supercapacitors (MSCs). However, when used as an electrode material alone, its poor capacitive performance and cycle‐life hinder the wide engineering applications. Herein, a polypyrrole (PPy)/Ag‐interdigitated electrodes MSCs is proposed, and the impact of aromatic sulfonic acid group anion modification on the electrochemical properties and flexibility of PPy/Ag MSCs is investigated. In the results, it is shown that different aromatic sulfonic‐acid‐based anionic dopants have different effects on the properties of PPy films. Among the prepared three PPy/Ag MSCs devices, PPy:anthraquinone‐2‐sulfonic acid/Ag MSCs have the highest areal capacitance (198.8 mF cm−2) at a current density of 0.5 mA cm−2, surpassing PPy:2‐naphthalenesulfonic acid/Ag MSCs (114.3 mF cm−2) and PPy:p‐toluenesulfonic acid monohydrate/Ag MSCs (89.7 mF cm−2). Furthermore, at a power density of 0.25 mW cm−2, the PPy:AQS/Ag MSCs exhibit a high energy density of 27.61 μWh cm−2, which is above the most of the previously reported PPy‐based MSCs. Therefore, in this research, the groundwork is provided for improving properties of flexible MSCs based on PPy.

Surface modification of nickel‐based 625 alloy is performed using a vacuum electron beam to improve its surface properties. The development of the microstructure is analyzed through scanning electron microscopy, X‐ray diffraction, and transmission electron microscopy. The tribometer RETC (MFT‐5000) is used to assess the wear resistance of the modified surface. The results demonstrate that the microstructure of the cladding zone exhibits columnar growth of the face‐centered cubic phase. As the scanning speed increases, the Cube texture s gradually weak, surface hardness increases, and both wear volume and wear rate decrease, thereby improving wear resistance. The maximum surface hardness is achieved at a scanning speed of 400 mm min−1, with a value of 489.8 HV, 1.977 times higher than the substrate. The minimum wear volume measures 0.1518 mm3, and the wear rate is likewise at its lowest point, measuring 0.506 × 10−5 mm3 N−1 m. Compared to the substrate, the material demonstrates an 88.44% reduction in wear rate and an 8.65‐fold improvement in wear resistance. These results demonstrate the significant enhancement of surface properties in Inconel 625, through surface modification using a vacuum electron beam.

2D transitional metal dichalcogenides (TMDs) have attracted great interest for their advantageous application in room‐temperature broadband photodetectors. Developing effective strategies to optimize the photo‐carrier dynamical process of monolayer TMDs is still urgently necessary to extend wavelength range and reduce dark current due to the theoretical limitation of their intrinsic band structure. Herein, an interesting approach is reported to realize broadband photodetection from 532 to 1550 nm with low dark current for the first time by using composition‐triggered growth of coherent atomic structures of enriched nanoscale mix‐phase (2H/1T') monolayer MoTe2(1−x)S2x alloys. The morphology and phase evolution at the nanoscale of monolayer MoTe2(1−x)S2x alloys are elucidated as affected by tiny formation energy (ΔE) by the chemical composition of S/Te atoms triggered. As‐grown enriched nanoscale mix‐phase (2H/1T') of monolayer MoTe2(1−x)S2x alloys devices exhibit typical n‐type conductivity properties. More interestingly, the devices show an extended photo‐response range from 532 to 1550 nm with reduced dark current to 10−10 A at 100 mV bias voltage. This work demonstrates that coherent atomic structure of enriched nanoscale mix‐phase (2H/1T′) monolayer TMDs alloys can be an alternative approach to obviously extend photo‐response wavelength range without increasing dark current for room temperature broadband photodetection.
