Semarang has reduced the stunting rate by 8,6% in 2021. The district with the highest prevalence in Semarang City is Central Semarang with a stunting rate of 7,25%. Efforts to reduce the prevalence of stunting need to be carried out further to reuduce the stunting prevalence in Semarang. Lack of milk consumption is one of the factors that causes stunting.
This study used a case-control design by examining nutritional status height/age (stunting) as the dependent variable, amounts, and frequency of milk consumption as independent variables, as well as mother's knowledge, father's education, mother's education, father's occupation, mother's occupation, family income, history Exclusive breastfeeding, and infectious diseases as confounding variables. The research subjects were 24 mothers of stunted toddlers and 24 mothers of toddlers who were not stunted. Bivariate data analysis was performed using the Chi-Square or Fisher test as an alternative. The bivariate analysis results were selected to be continued in multivariate analysis using the logistic regression test.
After controlling for confounding variables, the most dominant variable with the incidence of stunting is milk consumption, with an OR value of 12,5. Toddlers with milk consumption ≤38 g/day will have a 12,5 times higher risk of experiencing stunting.

The Relationship Between Sodium Consumption Patterns, Stress Levels, and Physical Activity with Hypertension of Elderly Participants at UPTD Puskesmas Rantau Tijang, Pugung District, Tanggamus Regency in 2022
Authors: Ernawati Dwi Testi
Published: March 2024

A person with hypertension has a rise in blood pressure above the healthy range of <120/<80. The amount of sodium that the body retains can impact blood prduction. Via the sympathetic nervous system's activation, which causes blood pressure to rise intermittently, stress causes hypertension. A sufficient amount of regular exercise significantly lowers blood pressure in hypertensive individuals. Elderly people frequently experience health issues. Many of these illnesses are non-communicable diseases like high blood pressure. The Province of Lampung has a 31,9% prevalence of hypertension. According to data on hypertension in the Tanggamus district, 120,276 persons have the condition.  The research objective was to determine the correlation between sodium consumption patterns, stress levels, and physical activity with hypertension in prolanis participants at the Rantau Tijang Public Health Center, Tanggamus Regency in 2022. This study used quantitative research using a cross-sectional research design. The population in this study were 63 people using the total sampling technique. Bivariate analysis in this study uses the Gamma test. The results showed a significant correlation between the level of stress and physical activity and hypertension with a p-value of 0,001 and 0,003 and no significant correlation between sodium consumption and hypertension with a p-value of 0,746.
The Relationship of Mother Characteristics and Childhood Nutrition Status to the Rough Motor of Toddlers 3-5 Years Old
Authors: Susanti Erna Evi
Published: March 2024

Toddlers aged 3-5 years are at an ideal period in the development process, especially in gross motor development. Gross motor skills are toddlers' ability to move by involving body structures and functions. The gross motor skills of toddlers can be influenced by several factors, namely maternal characteristics and nutritional status. The features of mothers involved in gross motor include knowledge, education, employment, and mother's care. It is also a factor in the nutritional status of children, so it will indirectly be connected to the child's motor.
This study used a cross-sectional design with purposive sampling techniques; the study sample comprised 37 respondents from toddlers and their mothers. The research was conducted at the Children's Poly, Kartika Pulomas Hospital, East Jakarta. The data measured were toddlers' nutritional and gross motor status using the DDST screening format.
The characteristics of respondents in the normal gross motor category were 16 toddlers (43.2%), while toddlers with suspected gross motor were 21 toddlers (56.8%). The bivariate analysis results showed that knowledge, maternal parenting, and nutritional status had a significant relationship with gross motor with a p-value of < 0.05. Age, education, and occupation had no association with gross motor with p-value > 0.05.

Published: March 2024

Diabetic nephropathy (DN) is one of the most frequent complications of diabetes. Early stages of DN are associated with hyperinsulinemia and progressive insulin resistance in insulin-sensitive cells, including podocytes. The diabetic environment induces pathological changes, especially in podocyte bioenergetics, which is tightly linked with mitochondrial dynamics. The regulatory role of insulin in mitochondrial morphology in podocytes has not been fully elucidated. Therefore, the main goal of the present study was to investigate effects of insulin on the regulation of mitochondrial dynamics and bioenergetics in human podocytes. Biochemical analyses were performed to assess oxidative phosphorylation efficiency by measuring the oxygen consumption rate (OCR) and glycolysis by measuring the extracellular acidification rate (ECAR). mRNA and protein expression were determined by real-time polymerase chain reaction and Western blot. The intracellular mitochondrial network was visualized by MitoTracker staining. All calculations were conducted using CellProfiler software. Short-term insulin exposure exerted inhibitory effects on various parameters of oxidative respiration and adenosine triphosphate production, and glycolysis flux was elevated. After a longer time of treating cells with insulin, an increase in mitochondrial size was observed, accompanied by a reduction of expression of the mitochondrial fission markers DRP1 and FIS1 and an increase in mitophagy. Overall, we identified a previously unknown role for insulin in the regulation of oxidative respiration and glycolysis and elucidated mitochondrial dynamics in human podocytes. The present results emphasize the importance of the duration of insulin stimulation for its metabolic and molecular effects, which should be considered in clinical and experimental studies of DN.
Set-Coloring Ramsey Numbers via Codes

Published: March 2024

For positive integers 𝑛, 𝑟, 𝑠 with 𝑟 > 𝑠, the set-coloring Ramsey number 𝑅(𝑛; 𝑟, 𝑠) is the minimum 𝑁 such that if every edge of the complete graph 𝐾𝑁 receives a set of 𝑠 colors from a palette of 𝑟 colors, then there is guaranteed to be a monochromatic clique on 𝑛 vertices, that is, a subset of 𝑛 vertices where all of the edges between them receive a common color. In particular, the case 𝑠 = 1 corresponds to the classical multicolor Ramsey number. We prove general upper and lower bounds on 𝑅(𝑛; 𝑟, 𝑠) which imply that 𝑅(𝑛; 𝑟, 𝑠) = 2Θ(𝑛𝑟) if 𝑠/𝑟 is bounded away from 0 and 1. The upper bound extends an old result of Erdős and Szemerédi, who treated the case 𝑠 = 𝑟 − 1, while the lower bound exploits a connection to error-correcting codes. We also study the analogous problem for hypergraphs.

La búsqueda de materiales de construcción sostenibles y asequibles en comunidades rurales, como el adobe en la sierra del Perú, enfrenta desafíos climáticos que limitan su uso y requieren un mantenimiento constante. Este estudio investiga la viabilidad de mejorar el adobe agregando estiércol de camélido. La metodología incluye un diseño experimental en Puno, Perú, con cinco niveles de dosificación de estiércol. Los adobes se fabricaron de manera tradicional, variando la dosis de estiércol y evaluando propiedades como peso seco, resistencia a la compresión y capacidad de absorción de agua. Se observó una relación lineal entre la dosis de estiércol y la reducción del peso seco, mientras que la resistencia a la compresión mostró una disminución no lineal y la capacidad de absorción de agua disminuyó linealmente. El análisis de varianza indicó efectos significativos de la dosis de estiércol en todas las propiedades evaluadas. Aunque la reducción del peso seco podría mejorar la resistencia a la intemperie, la disminución de la resistencia a la compresión y la capacidad de absorción de agua plantea desafíos. Dosis moderadas de estiércol podrían ser más apropiadas para equilibrar los beneficios y las desventajas. Este estudio proporciona información valiosa para la construcción sostenible en áreas donde abunda el estiércol, destacando la importancia de considerar cuidadosamente la dosificación en las decisiones de diseño y construcción. Se recomienda la validación experimental y la determinación de dosis óptimas para aplicaciones específicas.
Verbal strategies for expressing reciprocity – the case of Hebrew
Authors: Bar-Asher Siegal Elitzur
Published: March 2024

This paper delves into the semantics of the reciprocal construction recognized in the literature as "verbal" or "lexical" reciprocals. A common assumption is that predicates of this construction inherently encode a symmetric meaning, often marked morphologically in many languages. This paper advocates for a crucial distinction between two types of predicates: rec-predicates (e.g., the Hebrew verb hitnašek 'kiss') - a class of predicates that do not inherently denote symmetry but carry an underspecified meaning, so that in specific defined contexts, they can induce a symmetric reading. In contrast, sym-predicates (e.g., the Hebrew attribute zehe 'be identical') - this class of predicates inherently encodes symmetric relations. Drawing upon Winter’s (2002) typology of verbs, it is posited that rec-predicates are dyadic, taking two atoms as their arguments, while sym-predicates are monadic, with a single argument denoting a set. The analysis in this paper adopts Bar-Asher Siegal’s (2020) methodology for identifying strategies expressing reciprocity and is substantiated with a survey of the various syntactic structures in which the relevant predicates manifest, along with their diverse interpretations. The paper critically examines previous analyses of these predicates, scrutinizing both empirical and theoretical challenges encountered by these analyses. With a specific focus on verbal strategies for expressing reciprocity in Hebrew, the study, informed by the shared characteristics identified in previous research, suggests that the conclusions drawn for Hebrew may be applicable to other languages as well.
Psychological Distress During COVID-19: Its Association With Stress, Emotion Regulation, and Sleep

Published: March 2024

Background and Objective The COVID-19 pandemic has been linked to an increase in psychological distress and mental disorders worldwide. The objectives of this study were to investigate the correlates of psychological distress during the COVID-19 pandemic and explore whether the relationship between stress and psychological distress was mediated by cognitive emotion regulation strategies and sleep.Methods Four hundred ninety-six university students completed the Mental Health Inventory, the Insomnia Scale, the Cognitive Emotion Regulation Questionnaire, and the Perceived Stress Scale.Results Female gender and younger age were related to stress, sleep difficulties, and psychological distress. Stress was positively correlated with psychological distress and these two variables were associated with sleep difficulties, negative cognitive emotion regulation strategies (both positively), and positive cognitive emotion regulation strategies (inversely). In mediation analyses, there was a statistically significant positive direct/indirect impact of stress on psychological distress. The indirect pathways linking stress to psychological distress were: through an increase in negative cognitive emotion regulation strategies or a reduction in positive ones; through sleep difficulties; and through negative cognitive emotion regulation strategies and sleep. Female gender had a positive impact on sleep difficulty index, negative cognitive emotion regulation, and psychological distress.Conclusions The cognitive-emotional arousal associated with stress, as well as the maladaptive cognitive emotion regulation to cope with stress, may be implicated in the genesis and maintenance of sleep difficulties and distress during the pandemic. Strategies that include stress management, emotional self-regulation, and sleep hygiene should be implemented to promote the mental/psychological well-being of university students in future public health crises, such as the COVID-19 pandemic.

Published: March 2024

Metal oxide-based sensors have been extensively used for environmental monitoring, health, and safety. This work focuses on synthesizing ɑ-Fe2O3 and doping it with Ruthenium (Ru) to study its gas-sensing properties over flammable and hazardous gases. An anomalous behavior was observed during the Liquefied Petroleum Gas (LPG). This Ru-doped ɑ-Fe2O3 showed a charge carrier switching transition from n- to p-type conductivity due to Ru doping and the sensor’s operating temperature. The switching behavior on the Ru-doped samples happened between 3,000 and 4,000 ppm of the LPG concentrations. However, the Ru doping content did not seem to be affecting this transition except to alter the LPG response. The sensors’ operating temperature did alter the switching transition from n- to p-type conductivity. The temperatures varied from 175 to 225 °C. Metal Oxide Semiconductor (MOS) based on α -Fe2O3 nanoparticle doped with ruthenium (Ru- α-Fe2O3) was more selective towards LPG with a gas response of 24.41.

Protocol To Access Produce Images from the Imperfect Foods Dataverse on the Harvard Dataverse v1
Authors: Sharma Anjali
Published: March 2024

In the face of the impending challenge of feeding a growing global population, one-third of all food produced ends up as waste. A notable contributor to this problem is the wastage of a third of perfectly edible and nutritious fresh produce because they do not meet the high cosmetic standards expected by consumers. Eliminating this wastage of imperfect produce is therefore a crucial and sustainable means to increase food supply for a growing global population. This can be achieved through automated sorting of good, bad and imperfect produce using automation , robotics and machine vision. A prerequisite for such automated sorting are fast and accurate machine vision algorithms for successful differentiation between good, bad and imperfect produce. Training such algorithms requires large image datasets. While much work has gone into collecting images of good and bad produce, to the best of our knowledge, no such dataset exists for imperfect produce items. To fill this gap I have curated a dataset of good, bad, and imperfect produce items for a wide variety of fruits and vegetables. At this time of writing of this version of the protocol, images have been collected for just over 30 produce items and new ones are continuously being added. The dataset has been made publicly available on the Harvard Dataverse for use in training machine vision algorithms for sorting good, bad, and imperfect produce. It is our hope that this open dataset will contribute to improving research and practice for sorting and saving of imperfect produce in the food supply chain. In this protocol, we provide instructions on how to access these images for interested researchers and practitioners.

Published: March 2024

The properties of an open dump area are important to the application of the elements to the soils and their migrations through soil depth; therefore this study was investigated to evaluate the migration of elements in an open dump area. Soil samples were taken from three soil profiles, one of them was at an open dump site, and the second and third profiles were taken at different distances from the open dump site. In total eighteen soil sample were collected. Some soil physical and chemical properties were determined for each horizon. Total concentrations of Fe, Ni, Zn, Cu, Cr, and Cd were determined in each soil sample. The results indicated that the Fe had the highest value and the Cd had the lowest values in all soil samples. The orders of profiles for the total heavy (Ni, Cd, and Cr) metals were as follows: Profile1 > profile3 > profile 2. The order of profiles for the total heavy (Zn and Cu) metals was as follows: Profile 1 > profile 2 > profile 3. The mean value of total Ni ranged between 9.17 and 11.13, Cd between 0.29 and 0.37, Cr between 2.67 and 3.36, Zn between 6.90 and 17.23, and Cu between 4.90 and 12.52. The highest amount of total Ni, Cd, Cr, Zn, and Cu were observed in open dump area (profile 1) with the mean value (11.13, 0.37, 3.36, 17.23, and 12.52) respectively, compared to the profile 2 and 3. In general, the heavy metals did not show a specific pattern of distribution with depth in the three soil profiles, because there are many factors affecting migration of heavy metals in soil depth. In both profile 2 and 3, some of the heavy metals migrated in soil depth.

According to adiabatic temperature calculations, MgO was added to the reactant mixture in 10-40 vol.% range for preventing the melting and sintering of the formed Ni0.50Al0.50 and Ni0.55Al0.45 particles. After VCS, the products were ground into powder form and leached in 3M HCl solution in order to remove the MgO particles. After VCS, the samples which were obtained with 10 - 30 vol.% MgO addition were quite hard and difficult to grind. This indicated the partial sintering of the formed particles. It was relatively easier to grind into powder form the samples which contained 40 vol.% MgO. Therefore, it was determined that the most suitable MgO ratio for the formation of Ni0.50Al0.50 and Ni0.55Al0.45 powders was 40 vol.%. Formed powders were mostly in 5-100 µm particle size range. The formation of single phase pure powders was confirmed by the XRD analyses. A shift of about 0.1 degrees to higher 2-theta values was determined in the XRD peaks of the Ni0.55Al0.45 powder as compared to the Ni0.50Al0.50 phase, after annealing the powders. The results were in agreement with the crystallographic data.

Statistical analysis of COVID-19 data from China and NYC, using log-linear models, helps identifying high-risk groups like those aged over 65 and individuals with chronic health issues. According to the results of row effects model applied to the COVID-19 data set of China, we conclude that when the age group increases by one unit, the risk of getting COVID-19 disease is approximately 8 times higher for the patients having Chronic Obstructive Pulmonary Disease (COPD) than patients having hypertension, 9.37 times higher than patients with coronary heart disease, 13.37 times higher than patients having diabetes and cerebrovascular diseases and 10.16 times higher than patients having other diseases. According to the results of column effects model applied to the COVID-19 data set of NYC, we conclude that when the age group increases by one unit, the risk of death from the COVID-19 disease is approximately 2 times higher for the patients having choric health problem than the patients not having a chronic health problem. We believe that the empirical findings of the presented study will guide the policymakers to make provision for these disadvantageous groups for COVID-19 disease

Published: March 2024

There are many fit statistics used in the structural equation modeling, and new ones are consistently being developed. Because of the variety of fit statistics, it is very important to be able to decide which fit statistics are appropriate to use in studies. When comparing any two statistics, the asymptotic relative efficiency (ARE) between them is used. The ARE can use as a power of the fit indices is one of the familiar optimal criteria. It is frequently more convenient, and also more suggestive, to use a measure of relative merit called the relative efficiency. This study aimed to compare of fit indices using Fraser’s asymptotic relative efficiency. The data sets were derived from the multivariate normal distribution using the mean vector and covariance matrix. It was determined that the most efficient fit indices in terms of asymptotic relative efficiency were Z-Test of Wilson & Hilferty (W&H), Root Mean Square Error of Approximation (RMSEA), and Chi-Square indices, respectively.

Authors: Zortaş Süleyman , Yazarlı Hasret
Published: March 2024

Many researchers have studied permuting tri-derivation and generalized derivation in prime or semi-prime rings, BCK-algebras, lattices, d-algebras, MV-algebras and many algebraic structures. Later, they introduced the concept of generalized permuting tri-derivation by combining the concepts of generalized derivation and permuting tri-derivation. In this article, we have examined the properties of generalized permuting triderivation by adding conditions on their traces in prime or semi-prime rings. In addition, we examined the properties of two permuting triderivation by giving a relation between their traces.

Authors: Yazıcı Ayşenur
Published: March 2024

This study, it was aimed to investigate the antibacterial and antibiofilm activity of cis and trans-vaccenic acid against Pseudomonas aeruginosa. In the study, four different P. aeruginosa strains were used. Antibacterial activity was determined by microdilution and growth curve. The antibiofilm activity was determined by crystal violet assay. In addition, the effect of vaccenic acids on pyocyanin production was investigated. The minimum inhibitory concentration (MIC) of cis and trans-vaccenic acid against all strains was determined as 128-256 μg/mL, and the minimum biofilm inhibitory concentration (MBIC) value was 8-512 μg/mL. While vaccenic acids reduced cell growth in three strains, they also significantly inhibited pyocyanin production. In one strain, it inhibited biofilm formation without affecting cell growth. As a result, the presence of antibacterial and antibiofilm activity of cis and trans-vaccenic acid against P. aeruginosa was determined as potential agents in the fight against this bacteria.

Authors: Soylu Sinan
Published: March 2024

Crocus sativus L. has been used as spice, food colouring and medicinal plant for thousands of years. In this study, antioxidant properties and cytotoxic effect of saffron extract were evaluated in HT-22 cell lines. Malignant and non-malignant cells (L929) were cultured in DMEM medium and incubated with different concentrations of saffron extract in different solvents (water, ethanol, ethyl-acetate, n-hexane). Cell viability was determined by MTT assay. Antioxidant parameters such as DPPH, FRAP, total polyphenol and flavonoid amounts were measured. The highest DPPH value was found as 15.90±0.12 µg/mL in ethyl acetate solvent. Total polyphenols were 89.06±0.02 mg GAE/g extract, flavonoids were 76.98±2.08 µg QE/g extract and FRAP was 67.93±0.98 mg/g extract in ethanol solvent. In colon cancer, IC50 value 94±1.37 µg/mL was found to be the highest value. This is thought to be due to the high antioxidant capacity in ethanol solvent. While antioxidant capacity was not found to be high, antiproliferation effect was found to be high. Saffron may also be considered as a promising chemotherapeutic agent in cancer treatment in the future.

Published: March 2024

In this study, an anionic dyestuff bromophenol blue (BrPB) from the aqueous solution was removed by adsorption in the presence of bentonite (B), zeolite (Z) and graphene oxide (GO). The effects of pH, adsorbent amount, initial concentration of BrPB, temperature and time on adsorption were investigated. After the adsorption process, ultraviolet-visible region spectrophotometer (UV-VIS) was used to measure the amount of dyestuff remaining in the solution which is not adsorbed. It’s found that; the optimum values obtained for the adsorption process; the optimum pH value 5 for B and Z, 4 for GO; 0.03 g amount of adsorbent and 60 minutes for the equilibrium time. The compatibility of Langmiur and Freundlich isotherm models was found as Z> GO> B and GO> B> Z respectively. In terms of kinetics aspect, it was observed that all adsorbents were comply with pseudo-second order reaction kinetics. To be positive of ΔG° value for B and Z is of physical nature of adsorption, to be negative of ΔG° value for GO requires to be chemical nature of adsorption. When the obtained ΔH° values were examined, it was observed that the reaction was endothermic for B and Z and exothermic for GO. The negative value of ΔS° for B and Z adsorbent species indicates that the randomness between solid and liquid decreases, whereas the positive ΔS° value for GO indicates that the randomness between solid and liquid increases. The highest adsorption capacity value obtained after the measurements made under optimum conditions is 589 mg g-1 for GO and 15.7 and 19.8 mg g-1 for B and Z, respectively.
Options for the structure of an autonomous electric power system with a battery of hydrogen fuel cells

Published: March 2024

Background. Recently, interest in the problem of reducing the emissions of hydrocarbon fuel combustion products into the atmosphere and the use of alternative and renewable energy sources has sharply increased. This problem is relevant to both stationary and transport energy. One of the ways to reduce the harmful impact of primary energy sources in autonomous transport power plants on the environment is their hybridization, i.e., use, along with traditional energy sources (turbogenerators and diesel generators), of hydrogen sources of electricity (fuel cell batteries).
Aim. This study presents a justification of the optimal variant of the structure of an autonomous electric power system with a combined power plant based on hydrogen sources of electricity.
Materials and Methods. To achieve this goal, a comparative analysis of the parameters and characteristics of the power system elements was performed, as well as a method for modeling processes in the power system under study using the MATLAB Simulink package. Two options for the structure of an autonomous electric power system are being considered, namely, a common AC and DC bus. An analysis of the parameters and characteristics of these options was performed for three typical operating modes, namely, turning on a static load, direct starting of an asynchronous motor with a load on the shaft, and transferring consumers from power from a diesel generator to power from a battery of hydrogen fuel cells.
Results. In all considered modes, the VTE battery is characterized by a rapid response to load changes and stable efficiency. The nature of transient processes is aperiodic or low oscillatory, rapidly decaying. In terms of the number of semiconductor converters, filtering devices, and their total power, the structure of an autonomous power system with a common AC bus is more preferable.
