Conceptual Patterns in Plato's Parmenides
Authors: Poetsch Christoph
Published: July 2023

What is the notorious second part of Plato´s Parmenides all about? How does this second part help to face the systematic problems raised in the first part of the dialogue? To answer these questions, Christoph Poetsch develops a fundamentally new approach to what is perhaps the most controversially discussed text in the history of philosophy. By adapting methods from statistical linguistics and data science, he is able to detect hitherto unnoticed conceptual patterns in the deductions of Parmenides´ exercise. These patterns provide crucial new perspectives on the scope of the dialogue´s second part and offer means to address the problems raised in the first. Ultimately, the patterns suggest a complex constellation of multiple subjects and produce new evidence concerning the second deduction´s corollary, Plato´s ontology in general, as well as his concept of participation.

Effect of Curcumex on Serum Lipid Profile and Fasting Blood Glucose, HbA1c, and Insulin Resistance Levels in Type 2 Diabetic Patients: A Randomized, Double-Blind Clinical Trial
Authors: Zakerkish Mehrnoosh , Hemmati Aliasghar , Jalili Sebardan Faranak , Shakiba Maram Nader
Published: July 2023

Background: Diabetes is one of the causes of mortality worldwide. Turmeric, ginger, and black pepper have antioxidant and anti-inflammatory properties. Objectives: The present study was performed to evaluate the effect of Curcumex supplement (Turmeric herbal capsule (320 mg), ginger (150 mg), and black pepper (4 mg) on fasting blood glucose levels, HbA1c levels, insulin resistance, and serum lipid profile in type 2 diabetic patients. Methods: This study was a double-blind, randomized controlled trial conducted on 60 patients with type 2 diabetes who were randomly divided into the intervention (n = 30) and placebo (n = 30) groups. The intervention group received the Curcumex supplement capsule twice a day, every 12 hours for 90 days, and the placebo group received the same amount and duration of the starch capsule. At the beginning and end of the study, blood sugar indices, including fasting blood sugar levels, plasma insulin levels, HbA1C levels, HOMA-B, HOMA-IR, and lipid profile (high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol (Chol), triglyceride (TG), and very low-density lipoprotein (VLDL)) were assessed. Results: The mean values of age, gender, and body mass index (BMI) were not significantly different between the two groups before the study. There was a statistically significant difference and decrease between mean scores of blood sugar indices, including serum levels of HbA1C (P = 0.003), plasma insulin (P = 0.015), HOMA-IR (P = 0.001), fasting blood glucose (P = 0.06), and BMI (P = 0.016) after the intervention. After the intervention, no significant changes were not observed in other variables, such as HDL, LDL, Chol, TG, and VLDL. Conclusions: The consumption of curcumex supplement capsules in patients with type 2 diabetes reduces serum levels of HbA1C, plasma insulin, HOMA-IR, fasting blood glucose, and BMI.
Evaluación de las condiciones de rotura y la movilidad de los deslizamientos superficiales mediante el uso de técnicas de anáisis multivariante
Authors:   , Baeza Adell Cristina
Published: July 2023

Sobre la información (condiciones geológico-geomorfológicos) de laderas estables e inestables se han aplicado técnicas multivariantes, dando una valoración cuantificada de la rotura y movilidad. El análisis ha destacado que las zonas con mayor susceptibilidad de deslizamiento son aquellas que presentan grandes pendientes, grandes superficies de cuenca, ausencia de bosque, perfiles transversales cóncavos, importantes formaciones superficiales y bajas pendientes por encima de la zona potencial de rotura. Se han obtenido diversas funciones, combinación lineal de los anteriores factores, cuya utilidad como herramienta de predicción espacial de deslizamientos, ha sido claramente comprobada.

El análisis ha evidenciado el control que sobre la movilidad de los deslizamientos ejercen los obstáculos locales del recorrido, debidos a la presencia de vegetación, siendo mayor la propagación en zonas de prado que en zonas de bosque, cuando su trata de volúmenes pequeños (<10 elevado a 6 m3). Existencia de un comportamiento móvil diferenciado según el mecanismo de progresión de la masa. Finalmente el alcance, en términos de distancia horizontal recurrida, esta controlado principalmente por el volumen inicial movilizado.
Vulnerabilidad sísmica de edificios de acero
Authors:   , Bermúdez Mejía Carlos Alberto
Published: July 2023

En esta tesis se aplican los métodos estático no lineal y dinámico no lineal en el edificio prototipo y en otros seis representativos de las principales subclases de las estructuras de acero. Como resultado se expresan los umbrales de los estados de daño en función de los puntos característicos del espectro de capacidad bilineal. Se presenta una nueva propuesta de clasificación de las estructuras de acero de acuerdo con la EMS-98. Se cierra la investigación con un estudio estocástico detallado que considera la variabilidad probabilística de la acción sísmica, de las cargas verticales y de las propiedades físicas y mecánicas de los miembros estructurales. Se calcula la probabilidad de excedencia de los principales estados límite y de los umbrales de los distintos estados de daño. Como resultado se identifican los estados límite que con más probabilidad serán alcanzados y se recomiendan algunos factores de seguridad adicionales.

In this thesis nonlinear static and dynamic methods are applied to the prototype building, and to six more buildings, representing main subclasses of steel structures. As a result, the thresholds of damage state are expressed in function of the main points of the bilinear capacity spectrum. A new proposal of classification of steel structures, according with EMS-98, is presented. The last part of this thesis is a detailed stochastic study that considers probabilistic variability of seismic action, vertical loads and physical and mechanics properties of the structural members. Exceedance probabilities for the main limit states and thresholds of damage states are calculate. As a result the limit states most likely will be exceeded are identified. Finally some additional security factors are recommended.
Proposal of energy spectra for earthquake resistant design based on Turkish registers
Authors:   , Yazgan Ahmet Utku
Published: July 2023

This work proposes design energy spectra in terms of an equivalent velocity, intended for regions with design peak acceleration 0.3 g or higher. These spectra have been derived through linear and nonlinear dynamic analyses on a number of Turkish selected strong ground motion records. In the long and mid period ranges the analyses are linear, taking profit of the rather insensitivity of the spectra to the structural parameters other than the fundamental period; conversely, in the short period range, the spectra are more sensitive to the structural parameters and, hence, nonlinear analyses are required. The selected records are classified in eight groups with respect to the soil type (stiff soil and soft soil), the severity of the earthquake in terms of surface magnitude Ms (Ms ¿ 5.5 and Ms > 5.5) and the relevance of the near-source effects (impulsive and vibratory). For each of these groups, median and characteristic spectra are proposed; such levels are intended to correspond to 50% and to 95% percentiles, respectively. These spectra have an initial linear growing branch in the short period range, a horizontal branch in the mid period range and a descending branch in the long period range. Empirical criteria for estimating the hysteretic energy from the input energy are suggested. The proposed design spectra are compared with those obtained from other studies.

Este trabajo propone espectros de proyecto de energía en términos de velocidad equivalente, destinados a regiones con aceleración sísmica de proyecto 0.3 g o superior. Estos espectros se han obtenido a través de análisis dinámicos lineales y no lineales en una serie de registros sísmicos fuertes de Turquía. En los tramos de períodos largos y medianos los análisis son lineales, aprovechando la insensibilidad de los espectros con respecto a los parámetros estructurales, excepto el período fundamental y la masa; por el contrario, en el tramo de períodos cortos, los espectros son más sensibles a los parámetros estructurales y, por lo tanto, es necesario es necesario efectuar análisis no lineales. Los registros seleccionados se clasifican en ocho grupos con respecto al tipo de suelo (suelo duro y suelo blando), a la gravedad del terremoto en términos de magnitud superficial (Ms ≤ 5,5 y Ms > 5,5) y la relevancia de efectos de proximidad de falla (registros impulsivos y vibratorios). Para cada uno de estos grupos, se proponen espectros medianos y característicos; dichos niveles corresponden a los percentiles de 50% y 95%, respectivamente. Estos espectros tienen una rama inicial lineal creciente en el intervalo de períodos cortos, una rama horizontal en el intervalo de períodos medios y una rama descendente en el intervalo de períodos largos. Se proponen criterios empíricos para estimar la energía histéretica a partir de la energía de entrada. Los espectros de proyecto propuestos se comparan con los obtenidos a partir de otros estudios.

Arte y arquitectura moderna. 1851-1933 : del Crystal Palace de Joseph Paxton a la clausura de la Bauhaus
Authors: Pizza de Nanno Antonio
Published: July 2023

La Historia del Arte y de la Arquitectura considerada como una especialización temática, en nuestra opinión no tiene razón de ser. Si bien es cierto que existen producciones arquitectónicas -tal como se dan realizaciones literarias, artísticas, teatrales-, el campo de gestación de dichos productos pertenece a un ámbito necesariamente interactivo y difícilmente disciplinable. Así pues, esta propuesta de un programa docente que abarca los años de la modernidad trata de arte y arquitectura, pero también de urbanismo, literatura, filosofía, estética, según una visión operativa de corte pluridisciplinario. Su lugar de actuación es la ciudad de finales del siglo XIX, sumida en una fase de metropolización irreversible. Es en ella donde encontramos todas las ambigüedades prolíficas que caracterizan los momentos de transición: en efecto, en ambientes urbanos como los de Londres, París, Viena, Berlín, San Petersburgo, Moscú, Chicago, Nueva York, sujetos a imponentes metamorfosis urbanístico-arquitectónicas, destaca la riqueza de las relaciones entre lo nuevo y lo viejo, en un contexto en el que los signos del pasado conviven con proyecciones, a veces temerarias, hacia el futuro.

Puertas adentro : interioridad y espacio doméstico en el s. XX
Authors: Parodi Aníbal
Published: July 2023

Puertas adentro, dentro y fuera, interior y exterior, envolvente y espacio. Existen, sin duda, pocos diálogos que se vinculen de un modo tan determinante con la identidad más íntima del hecho arquitectónico. Parecería que todo el conflicto que supone la concepción del espacio se resume, precisamente, en la magia que integra y divide estos hemisferios complementarios en permanente interacción. El presente trabajo decide explorar el fenómeno de la interioridad desde la determinante investigación espacial que supone el diseño de la vivienda. Se aleja voluntariamente del espíritu comprehensivo y registral de los textos de historia de la arquitectura y se concentra en un universo considerablemente reducido respecto a la producción sumamente interesante del siglo pasado. Tan solo diecisiete viñetas para presentar el fluir del pensamiento arquitectónico en el transcurso de todo un siglo. Esta selección de ejemplos -presentada en orden cronológico- intenta desplegar un abanico lo más completo posible de las distintas actitudes de aproximación al diseño del espacio interior y su equipamiento, para lo cual se recurre tanto a ejemplos paradigmáticos como periféricos a los supuestos centros de producción cultural. El trabajo se complementa con una presentación interactiva en CD-ROM. El proceso de investigación se deja, sin embargo, voluntariamente abierto, lo que estimula el desarrollo de otras historias -transversales y complementarias- que arrojen nueva luz sobre el fascinante universo del espacio interior.

El presente libro establece los fundamentos de un "saber-hacer" arquitectura que no se identifique únicamente con el negocio de la construcción, en concordancia con las posturas humanistas de Occidente. Se estructura en tres partes complementarias, dedicadas a las tres dimensiones básicas de la arquitectura: la estética, la ética-política y la científica, unidas a través de un núcleo "dialógico-social" del hecho arquitectónico que da solidez, simultáneamente, tanto al diseño arquitectónico como a su construcción y a su uso. El libro se complementa con un amplio anexo que contiene la versión castellana de artículos publicados recientemente en otros idiomas sobre lo últimos avances en la comprensión cultural de la significación de la "arquitectura" de nuestra mente, de nuestro territorio y de nuestra sociedad.

Path planning of mobile robot based on improved artificial potential field method
Authors: Bing LI
Published: July 2023

Artificial potential field method is widely used in robot path planning because of its simplicity, efficiency and smooth path generation. In this paper, based on the introduction of the basic principle of the artificial potential field method, the limitations of the algorithm are analysed in depth, and improvement methods are summarized for these problems. Aiming at the problem that the target near the obstacle is unreachable in the traditional artificial potential field method, an improved repulsive force potential field function is used to introduce the distance between the robot and the target point into the potential field function, so that the potential field of the target position is minimized in the global potential field, so that the robot can successfully reach the target. Using the obstacle connection method, the robot can quickly get rid of the local minimum point, go out of the local minimum area, and complete the path planning. The simulation results show that the method is effective.

Published: July 2023

In tribute to the philosophy of Bat-Ami Bar On, this article draws upon her Arendtian analysis of fascism to explore recent dynamics of ethnic nationalism in the US. Whereas Bar On analyzed the problem of citizen-soldiers, this study extends analysis toward the citizen culture-soldier, suggesting that recent dynamics in the US are suggestive of a Cultural Revolution that threatens the inclusive practice of citizenship required of democracy. Bar On’s work motivates philosophers to not be lulled into acceptance of anti-democratic practices of citizenship. The values of respect, equality, and equity suggest that another form of citizenship should be practically pursued.

Reading ability is one of the basic language skills. By reading students will apply another ability that is speaking. And also students who are unable to read will find it difficult to fulfill their abilities. Learning to read is the most important part of life, because it is the beginning of our systematic knowledge of the learning process and one of the keys to success in following the process. When learning in class there is interaction in the learning process of teachers and students. Teachers and students are a very important part in determining the success of learning objectives. Reading is a skill that must be taught to children from an early age. If a child of primary school age cannot master early reading skills, he or she will experience many difficulties in learning various subjects in later grades.

Persistence and diversity of Theileria parva in East Coast fever vaccinated and unvaccinated cattle
Authors:   , Magulu Emelesiana Cyprian
Published: July 2023

Infection and Treatment Method (ITM) has been practiced in Tanzania for over 20 years now as a prevention method against East Coast Fever (ECF). However, there is less information regarding the persistence of the Theileria parva parasites after a long-time lapse after vaccination. Likewise, the implication of the potential exchange of genetic information is largely unknown as regards ECF vaccination outcomes. A total number of 336 cattle samples were collected from Loiborsoit, Emboret, Esilalei, Manyara ranch, Mswakini, Tanga Mruazi farm and Tanga Leila farm in March of 2018. Samples were then screened for Theileria parva using nested PCR and the overall prevalence of carrier state was 34.5%, with a significant higher prevalence among the vaccinated cattle group 43% (103/239) compared to the unvaccinated group 13.4% (13/97) (p<0.000). Similarly, higher prevalence emerged among the cattle grazing close to the wildlife 38.2% (107/280) compared to the ones grazing far from wildlife 16.1% (9/56) p<0.001. The carrier state persisted up to 132 months post vaccination. Minisatellite 7 (MS 7), microsatellite 2 and 5 (ms 2, ms 5) markers were used to characterize genetic diversity. Whereby parasite diversity across cattle groups was determined by the mean number of alleles, and expected heterozygosity. Manyara ranch had the highest parasite diversity with all the markers. This study concludes that vaccination against ECF and the wildlife interface has an influence on the diversity of Theileria parva parasites, as the highest number of alleles and parasite diversity were shown in the vaccinated cattle and the ones in close proximity to wildlife interface.
Antimicrobial and cytotoxicity activities of conyza bonariensis, tribulus terrestris and rubia cordifolia growing in Arusha, Tanzania
Authors:   , Ghwanga Ambrose
Published: July 2023

The aim of this study was to evaluate antimicrobial, synergistic and cytotoxicity activities of Conyza bonariensis, Tribulus terrestris and Rubia cordifolia growing in Tanzania. Two fungal strains, four Gram-negative bacteria and one Gram-positive bacterium all being human pathogens were tested using 96 well microdilution method. The minimum inhibitory concentrations (MICs) was used to determine antimicrobial and synergistic activity of the extracts whereas LC50 values on brine shrimp larvae (Artemia salina) were used to determine cytotoxicity of the plants extracts. About 14% of all uncombined extracts (224) demonstrated moderate antimicrobial activity with MIC value range of 0.7825 mg/mL - 1.5625 mg/mL. Synergistic effect was evaluated by treating the microbes by mixture of extracts. A binary combination of extracts had synergistic effect in all combinations and MIC for each microbe was lowered. About 44% of mixed extracts showed moderate antimicrobial activity with MIC value range of 0.7825 mg/mL - 1.5625 mg/mL. Strong antimicrobial activity of 0.3906 mg/mL was recorded for CBLC-CBLE, CBLC-CBRC and CBLC-TLC against E. coli and S. typhi. The comparison between MIC of plant extracts was done using analysis of variance (ANOVA) and differences among the means were determined for significance at P = 0.05 using statistical package for social science. The order of antimicrobial effectiveness of the plants was C. bonariensis ˃ T.terrestris ˃ R. cordifolia with average MIC 7.49, 10.2 and 13.6, respectively for all microbes. Root extracts and extracts extracted by ethyl acetate were the most effective plant part and solvent, respectively. Candida albicans and Salmonella typhimurium were the least sensitive fungus and bacterium to most of unmixed extracts. All extracts were non-toxic to brine shrimps except TTC, RCA and CBM with mildly toxicity of LC50 52.5069, 75.8198 and 79.0076, respectively. Pharmacologists and herbalists should consider synergism of plant extracts for prescription of herbal medicines. Key words: Antimicrobial, extract, MIC, synergistic effect, toxicity.
Effects of pesticidal plants on legume pollinators’ attraction in the field and bruchids control in storage
Authors:   , Godifrey Juliana
Published: July 2023

A randomized complete block design was used to set up field and storage experiments to evaluate the effects of pesticidal plants on common bean pollinators’ attraction in the field and Callosobruchus maculatus control in cowpea storage. Pesticidal plants Hyptis suaveolens, Osimum suave, Dysphania ambrosioides and Sphaeranthus suaveolens were planted as field margin plants (FMPs) in a plot size of 5 m x 5 m in a study area of 75 m x 75 m. Pesticidal leaf powder of H. suaveolens, O. suave and D. ambrosioides were used at the rates of 0, 30, 60 and 90 g 1.5 kg-1 of cowpea seeds in storage. The results showed that, all FMPs attracted a good number of pollinators, but O. suave attracted more pollinators than the rest of FMPs. More pods per plant were produced in open pollinated bean plants than in self-pollinated (netted plants) and the control plots (no margins). Higher dosages of plant leaf powders at 60 and 90 g for H. suaveolens and D. ambrosioides and 90 g for O. suave significantly (P ≤ 0.001) affected insects’ mortality, survival and reduced seed damage. Comparatively, H. suaveolens and D. ambrosioides at 90 g was more effective in inhibiting egg deposition by C. maculatus just as successful as the positive control. Therefore, the findings of this study indicated O. suave to have high influence in attracting pollinators, while H. suaveolens and D. ambrosioides at high dosage were effective in protecting the stored cowpea seeds against C. maculatus.

Authors:   , Chawe Kissa
Published: July 2023

A set of 41 lablab bean accessions were evaluated based on morphological characteristics and farmers’ participatory selection was performed based on agronomic and sensory traits. An experimental plot was laid down in augmented block design where accessions collected from different gene bank were sown at spacing of 75 cm x 40 cm. Descriptive and multivariate analysis based on 21 quantitative traits revealed high coefficient of variation (CVs) in secondary branches, seed yield, and pods per plant. Principle component analysis (PCA) showed that first 6PCs contributed to 83.3% of the total variation. Days to maturity had significant correlation with days to podding (0.855) and flowering (0.821). Seed yield per plant had strong association with pods per plant (0.793). Cluster analysis based on Un-weighted Pair Group Method Average (UPGMA) grouped 41 accessions into 7 clusters based on traits kinship. Cluster II, VI and VII are genetically different from other clusters. Farmers selected ten best accessions, D163, D137, D88 D27, D85, D155, D7, D159, D151 and D140. The selection criteria perceived were diseases and pest resistance, pod per plant, earliness, bulk leaves, high yield, seed colour, seed size, drought tolerance, plant height and growth type. Farmers’ preferred traits; high yielding, better taste, earliness and short cooking time need to be incorporated in bean breeding programs. In sensory evaluation, panelists chose accessions D137, D85 and D88 due to good sensory potential for home consumption. This study recommends accessions D137, D163, D85, D208 and D88 for further evaluation on different locations for developing lablab varieties in Tanzania.

Schistosomiasis is one of the chronic threatening but neglected parasitic disease caused by trematode worms under genus schistosoma. Praziquantel is the only drug recommended by WHO for the treatment of all forms of human schistosomiasis. Praziquantel is currently facing challenges, among which selective efficacy and resistance, making it of high imperative searching for new anti-schistosomal drugs. This study aimed to evaluate schistosomacidal activity of Lannea schimperi and Searsia longipes extracts against cercariae, schistosomula and adult stage of Schistosoma mansoni. Bioassays were conducted in vitro in 24 well plates for cercariae and schistosomula and 6 well plates for adult worms. Lannea schimperi and Searsia longipes expressed highest activity against schistosomula at 1 to 2 mg/ml and 2 mg/ml respectively with the mortality rate of 100% after one hour. Searsia longipes and Lannea schimperi exhibited 100% activity against adult worms at the dose range of 0.5 to 2 mg/ml and 1 to 2 mg/ml respectively after 48 hours of exposure. One hundred percent mortality of the cercariae was observed at the concentration range of 1 to 2 mg/ml and 2 mg/ml for Searsia longipes and Lannea schimperi respectively. Both extracts exhibited good margin of safety on Swiss albino mice with LD50 above 2000 mg/kg bwt. Lannea schimperi and Searsia longipes expressed significant cytotoxicity on brine shrimp larvae with IC50 of 150.0478 and 280.7875 μg/ml respectively. Extracts have revealed to contain flavonoids, saponnins, tannins and glycosides. To the best of my knowledge, schistosomacidal activities of Lannea schimperi and Searsia longipes are reported for the first time.

Published: July 2023

The use of cattle manure in agricultural fields improves soil quality and contributes to nutrient recycling when applied back to the soil compared with synthetic fertilizers that are associated with high cost and limited access. The Community Action Research Project was conducted at Lushoto and Korogwe Districts, exploring the practices associated with manure management and utilization in selected seven villages. Two hundred farmers were interviewed, 120 samples of manure collected and 112 soil samples taken from farm applied with (66) and farm not applied with manure (66). The soils analysis of Nitrogen (N), Phosphorus (P), Potassium (K), Organic Carbon (OC), Organic Matter (OM), soil pH, Cation Exchange Capacity (CEC) and Electro Conductivity (EC) were done. Analytical results show that in the farms applied with manure the average of NPK values were 0.21%, 0.23% and 1.63% respectively while those not applied with manure had average NPK of 0.12%, 0.11% and 0.61% respectively. Other parameters in farms applied with manure were pH 6.95, EC 0.12 dS/m, CEC 24.26 Meq 100g-1 of soil, SOC 2.43 % and SOM 4.19%. The average chemical properties of pit compost manure were 1.78%N, 1.58%P, and 1.28% K while the surface stored manure had 2.51%N, 1.78%P and 1.23%K. Farms applied with manure showed a relative increase in nutrients and the surface stored manure had increased nutrient content compared to pit composite. The study observed poor manure handling practices. This shows the need for training these farmers on proper manure management. Studies on understanding the effects of inherent manure microbial composition and environmental factors such as temperature and moisture on manure quality under the different storage practices are recommended.

Authors:   , Ndala Rachel I.
Published: July 2023

A study was conducted in Iringa and Arusha regions of Tanzania to determine the status of the of Late blight disease (LBD) on tomato and effect of synthetic fungicides on the disease. Leaf samples with symptoms of the LBD were collected from three farms per village in each region, and transported to the Nelson Mandela African Institution of Science and Technology (NM-AIST) laboratory for detection of the LBD-causing pathogen(s). In addition, field trials were set in each region to find out the efficacy of chemical fungicides on LBD control. Moreover, extracts from Plectranthus barbatus, Sphaeranthus suaveolens, Lantana camara and Tephrosia vogelii were tested in-vitro for their effects on the LBD-causing Phytophthora. The results showed that, the LBD was present in the study locations. In addition, despite the application of different synthetic fungicides on tomato, the percentage LBD incidences and severities were higher ranging from 42.1, 52.60 and 49.56, 39.39 in Iringa and Arusha regions, respectively. Such results implied that synthetic fungicides used by farmers in the study area do not fully control the LBD. The results also showed that there was significant difference (p ≤ 0.001) between the effects of different plant extracts against the LBD. The crude extracts from P. barbatus, S. suaveolens and L. camara exhibited growth inhibition of P. infestans (in-vitro) almost similar with synthetic fungicide used as positive control. This study therefore, proposes P. barbatus, S. suaveolens and L. camara as candidates for further studies in developing alternative bio-fungicides against P. infestans in Tanzania.

Infant and young child feeding practices rank among the most effective interventions to promote child growth and development. Improving the quality of complementary food has been observed as an important strategy for promoting child growth in resource-poor settings. Therefore, the objective of this study was to design a safe and nutritious model formula that meets nutritional requirement for infants and young children aged 6 – 23 months. The objective was achieved by conducting a cross-sectional study aimed to assess the nutritional status of 394 children and identify factors associated to under-nutrition. Then, complementary flours were collected randomly from selected households and analyzed for macro- and micro-nutrients, phytate content and presence of aflatoxins. Exposure assessment was done to evaluate the contribution of aflatoxins exposure on nutritional status of children. Finally, the model formula was designed using commonly consumed foods to meet the nutritional requirements for children. Data analysis was performed by using SPSS (IBM version 21), ENA for smart, Microsoft Excel and LINDO (version 6.1). The results showed that prevalence of stunting was 40.4% (95% CI; 29.8% - 50.9%). Children aged between 12 - 23 months were more stunted compared to those aged between 6 – 11 months (p ≤ 0.001). The age of introducing complementary foods (AOR = 13.3, 95%CI, 2.6 – 67.6), maternal education (AOR = 5.5, 95% CI, 1.0 – 9.8) and residence in Chamwino district (AOR = 3.2, 95%, 1.3 – 5.9) were identified as factors associated with stunting. Analysis of cereal-based complementary foods indicated that protein and fat content ranged from 1.17 - 11.17 g/100 g and 0.61 - 11.19 g/100 g respectively. A significant difference in protein content between composite cereals and other types of complementary foods was observed (p ≤ 0.001). Sorghum had the highest iron and phytate content of 8.37 mg/100 g and 1176.8 mg respectively. Aflatoxins contamination was detected in 42.5% of home-made complementary flours at the levels ranging from 0.3 μg/kg to 2,128 μg/kg. There was a significant association between stunting and infants dietary exposure to aflatoxin B1 (p = 0.05, 95% CI; 0.019 - 0.028). Cereal-based complementary foods consumed by the studied children were observed to have dual burdens in a sense that they contained high level of phytate and being contaminated with aflatoxins to the levels of health concern that may contribute to impairment of growth. Developed optimized model formula serves as a basis for ensuring adequate nutrient intake, minimized intake of phytate and reduced dietary exposure of infants

The term kindergarten came from a German origin that means “children’s garden. It serves as a transition period from home or preschool to formal education. The main purpose of kindergarten is to provide foundation for the child’s wholistic development. In Kindergarten program, children are engaged in different activities that are age appropriate. These activities are designed to promote the physical, cognitive, emotional and social development of children . Many research have shown that during the early years, rapid brain development occurred forming the foundation for future academic success. This stage is crucial because it is during this time that they develop the essential skills to prepare them for Grade 1 . This study sought to find out how the implementation of a kindergarten curriculum affects the readiness of our young learners for formal education. Several variables related to curriculum were considered in this study. These were the objectives of kindergarten curriculum in the Philippines, the Budget of Work provided by DepEd, the instructional materials used, the teacher’s competencies, learning environment and lesson planning. It was then correlated with the basic competencies expected from kinder pupils in terms of health and well-being, socioemotional development, language, literacy and communication (listening/viewing, speaking, reading, writing), mathematics and understanding the physical and natural environment. This research was conducted in the Schools Division of San Pablo wherein 70 kindergarten teachers from public schools were the respondents. The research method used wasa quantitative descriptive method with Pearson product-moment correlation. The result showed that there was a significant relationship between the implementation of the curriculum and the pupils acquired basic competencies.

The study was conducted to identify the level of students’ profile, cognitive, emotional empathy and empathic concern be a predictive factor of interpersonal skills and constituted the basis for enhanced Homeroom Guidance activities. Using a descriptive correlational design, two hundred (200) Grade 9 students from Sico 1.0 Integrated National High School during school year 2022-2023 were conveniently selected as respondents of the study. Four (4) expert teachers validated the instrument. This study used standardized tests namely: Interpersonal Reactivity Index (IRI) of Davis (1980) with 28 items, and Empathy Formative Questionnaire with 15 items were the questionnaires and answered by a 5-point Likert scale. Interpersonal skills questionnaire was made by the researcher consisting of 35 items. The Pearson Product- Correlation Coefficient was used to analyze the data. The results revealed that cognitive empathy has a high significant relationship (r=.609) and level of the emotional empathy has a moderate positive significant relationship (r=621), while, empathic concern of respondents has a low positive significant relationship to interpersonal skills of respondents (r=.465) at a significance level of 0.01, Sex was significantly associated with emotional empathy at the .05 level of significance. Moreover, monthly income was significantly associated with empathic empathy at the .01 level of significance. Marital status, birth order, and place of residency were not significantly associated with any of the types of empathy. Sex was found to have a significant relationship with interpersonal skills, as indicated by a chi-square value of 9.994 and a p-value of .019. Marital status, birth order, monthly income, and place of residency, on the other hand, did not demonstrate a significant relationship with interpersonal skills. The model as a whole is statistically significant in predicting students' interpersonal skills, as evidenced by the F-value of 51.003 and a p-value less than .01. This suggests that the combination of cognitive empathy, emotional empathy, and empathic concern significantly contributes to the prediction of students' interpersonal skills.
