Application of Instrumental Analytical Methods in the Study of Sewage Sludge
Authors: Mezhevova A.S. , Beresteneva Yu.V.
Published: January 2023

Instrumental methods of analysis were used to study sewage sludge formed during its processing by the enzyme-cavitation method for further water reuse. It was revealed that sewage sludge samples are multiphase porous aggregates containing both amorphous and crystalline components in their structure. X-ray phase analysis helped to determine the mineralogical composition, as well as the presence of fertilizing properties. Transmission electron microscopy showed that the studied sewage sludge has several scale structural levels of porosity from 5 nm to 6 μm. The sorption properties of sewage sludge, as well as the ability to absorb and retain water, were revealed.

Published: January 2023

Increases in food prices in Nigeria have raised huge concerns on the impact welfare of poor households who have substantial share of their spending on food. This study investigated the welfare effects (including the direct and substitution effects) of food price changes on households in Nigeria. The study employed time series data on food prices from 1991-2013 and household survey data obtained from the National household Survey (wave 2). We group household consumption expenditure on different food and non-food commodities into nine (9) namely; fish, meat, pulses, fruit & vegetable, fat & oil, beverages, wheat, rice, corn, and others. Welfare effect was analyzed by compensating variation. The results showed that a safety net program would net to transfer an amount equivalent to 0.76%, 0.26% and 1.02% of the total national consumption to fully compensate the poorest quintile in rural, urban and at the national level respectively. And also, in the richest losers’ quintile about 1.29% of the aggregate national consumption will be required by a safety net program to fully compensate them overall. The study concluded that food price changes related significantly with welfare status of the respondents as tested by CV model. Welfare gain was enjoyed mostly by urban household whose mean compensated variation was as high as 18% compared with 14% for rural household.

Indo-China Trade Relations
Authors: Yadav Arti , Hassan Munir
Published: January 2023

This study takes an account of the growth and development of economic ties between China and India since the inception periods. It examines the aspects that have added to the growth of this vital feature of their relationship. Further, it also highlights the obstacles, in particular to the economic relations in terms of trade scenario between the two. In addition, it provides that the future growth in economic ties of Indo-China will depend on how the two economies can effectively deal with matters such as trade inequity, border issues, lack of adequate infrastructure, market capture, and regulatory environment. These issues, if conquered, may show mounting growth in the existing degree of economic relations between the two. Therefore, strings of assistance and rivalry, both subsist at the same time.
The Modern State After Kant A Materialist Approach
Authors: Doust Dariush M.
Published: January 2023

This article proposes an encounter between Kant’s political doctrine and Marx’s materialist method. The primary aim of this materialist critique of Kant is to discern the structure that determines the specific mode of functioning of the modern state. The article starts with Kant’s conception of freedom and law and relates these concepts to his theory of history. In the first and second sections, Kant’s political doctrine is subject to a critical reversal that more closely engages with Marx’s critical materialist approach. The article then concludes upon a new, topological approach to the ternary structure involving the intersection of three “rings”—capitalist circulation, the state in its legal effective reality, and measured labor forces in production.
Les Actions en Responsabilité Médicale pour Faute de Diagnostic. Aspects de Droit Comparé Français et Ivoirien
Authors: Agbodo Jean Paul
Published: January 2023

Si l’erreur de diagnostic ne constitue pas en elle-même une faute pénale, il en est tout autre de la faute de diagnostic qui prouvée, permet au patient d’engager la responsabilité du médecin- auteur du diagnostic, tant devant les juridictions judiciaires qu’administratives, outre les voies de règlement amiable du litige. Cette efficacité avec laquelle le législateur français entend prendre en compte les actions des patients-victimes contre les professionnels de santé pour la réparation des préjudices subis, reste inexistante en droit ivoirien, malgré les multiples dénonciations des manquements fautifs des médecins dans la prise en charge de leurs patients. Toute chose qui appelle aujourd’hui, à l’impérieuse nécessité d’une réforme du droit de la santé ivoirien au regard du droit français. Afin de garantir au patient un traitement sérieux de sa pathologie conformément aux données acquises par la science.

El ostión de roca Striostrea prismatica es un recurso natural de gran importancia comercial en el Pacífico mexicano, Nayarit ocupa el primer lugar en producción de ostiones en esta región. Uno de los principales sitios de extracción de ostiones de roca en Nayarit es Santa Cruz de Miramar, y de acuerdo con los pescadores de la zona, recientemente se ha observado una disminución en los volúmenes de extracción. El objetivo de este trabajo fue describir la biología reproductiva del ostión de roca y su relación con la temperatura y la clorofila-a. Para ello, se obtuvieron 322 ostiones de la pesca comercial entre enero y diciembre de 2014. Los organismos se pesaron y midieron de forma individual, mientras que las gónadas se procesaron por histología. Se estimó la proporción de sexos, el índice de condición, el ciclo reproductivo y la talla de primera madurez. La temperatura superficial y la clorofila-a variaron de 25.5 a 30.6 °C y de 0.96 a 3.17 μg L−1, respectivamente. La proporción de sexos fue 1 M: 0.6 H (p < 0.05); el IC fue mayor de abril a junio, mientras que la relación Ps/Ph fue mayor de abril a agosto. El desove se produjo entre mayo y septiembre. La temperatura mostró una asociación directa con la madurez y desove (p < 0.05). La talla de primera madurez fue de 80.2 mm. Los resultados de esta investigación podrían contribuir al manejo de la pesquería de este recurso en la zona.

Un pez nativo cada vez más estudiado en Latinoamérica es el Dormitator latifrons, pero se desconoce el efecto de altas densidades de siembra en su fisiología. El objetivo fue determinar el efecto de diferentes densidades de siembra en el crecimiento y parámetros sanguíneos. Se utilizaron organismos silvestres aclimatados al cautiverio, alimentados al 4% de biomasa total durante 60 días. Se registró peso y longitud inicial y final, determinando índices de crecimiento y supervivencia. Al final del experimento se tomó una muestra de sangre al total de organismos para evaluar parámetros sanguíneos No se encontraron diferencias en el crecimiento y supervivencia entre las diferentes densidades. Los parámetros sanguíneos no fueron afectados por la densidad, a excepción del estallido respiratorio, todos se encuentran entre los rangos de referencia de buena salud para peces. La especie no presentó señales de estrés o respuesta inmune adversa asociada al incremento de la densidad de cultivo.

Authors: YAZAR Taha , TUTAL Özgür
Published: January 2023

Ters-yüz öğrenme son yıllarda oldukça ilgi görmekte ve ters yüz öğrenmenin akademik başarı, derse yönelik tutum, kalıcılık, öz-yeterlik, eleştirel düşünme becerisi gibi farklı değişkenler üzerindeki etkisi gerçekleştirilen araştırmalarla incelenmektedir. Ters-yüz öğrenme yaklaşımının öğrenmeyi yönlendiren etkili bir güç olan motivasyon üzerindeki etkisini sınamak için de Türkiye ve yurtdışında çeşitli araştırmalar yapılmıştır. Ancak ters-yüz öğrenmenin etkililiğini inceleyen çalışmaların sonuçları farklılık göstermektedir. Kimi çalışmalar ters-yüz öğrenmenin öğrencilerin motivasyonu üzerindeki etkisinin pozitif olduğu sonucuna ulaşırken, kimi çalışmalar istatistiksel olarak anlamlı bir fark bulunmadığını, bazı çalışmalar ise negatif bir etkinin söz konusu olduğunu bildirmişlerdir. Bu araştırmanın amacı, ters-yüz öğrenmenin motivasyon üzerindeki etkisini inceleyen deneysel ve yarı deneysel çalışmaların sonuçlarını meta-analiz yöntemiyle analiz etmektir. Araştırmada yaklaşımla ilgili yurt içinde ve yurt dışında yapılmış deneysel ve yarı deneysel çalışmalara ulaşabilmek için alanyazın taraması yapılmıştır. Belirlenen anahtar kelimelere göre yapılan tarama sonucunda listelenen 4463 çalışmadan dâhil edilme ölçütlerine uyan 17 çalışma meta-analiz sürecine tabi tutulmuştur. Bu çalışmalardan 14’ü pozitif, üçü negatif etki büyüklüğüne sahiptir. Pozitif yönlü çalışmaların ikisi zayıf, beşi küçük, altısı orta ve biri güçlü etki büyüklüğü düzeyindedir. Gerçekleştirilen analiz sonucunda ters-yüz öğrenmenin genel etki büyüklüğü değeri rastgele etkiler modeli ile 0.077 ile 0.594 güven aralığında 0.336 olarak hesaplanmıştır (%95 CI, SE=0.132). Elde edilen bu sonuç, ters-yüz öğrenme yaklaşımının geleneksel eğitim süreçlerine kıyasla motivasyon üzerinde küçük düzeyde ve pozitif bir etkiye sahip olduğunu göstermektedir.

Zatrudnienie skazanych w latach 2009–2021. Analiza danych statystycznych
Authors: Rozik Anita
Published: January 2023

Artykuł porusza problematykę zatrudnienia osób pozbawionych wolności (skazanych oraz ukaranych). Poświęcony jest on głównie kwestii zmian w strukturze zatrudnienia osadzonych na przestrzeni lat oraz minimalnej płacy więźniów. Doktryna prawa karnego wykonawczego przypisuje zatrudnieniu różnorakie funkcje, wśród których można wskazać funkcję ekonomiczną, funkcję zdrowotno-higieniczną, funkcję represyjną, ale największe grono zwolenników ma jednak funkcja resocjalizacyjna (wychowawcza). Wysuwając na pierwszy plan walor wychowawczy, nie można pominąć faktu, że ,,dla skazanych praca nadal pozostaje jednym z podstawowych obowiązków, w cieniu którego pozostaje ich prawo do pracy”. W niniejszym artykule przedstawiona została sytuacja więźniów na rynku pracy oraz dynamika wzrostu zatrudnienia na podstawie danych z lat 2009–2021 (łącznie dwunastoletni okres). Praca prezentuje dane statystyczne, których głównym źródłem jest opracowanie Centralnego Zarządu Służby Więziennej — Roczna informacja statystyczna za lata 2009–2021. Z przeprowadzonej analizy wynika, iż bezwzględna liczba pracujących więźniów na przestrzeni lat wzrasta.

Between 2013 and 2019, we examined the body composition and lifestyle of 18–24 years old female students (n: 273) by random sampling at the Konstantin Philosopher University in Nitra and at the János Selye University in Komarno. The physical condition, body composition, fitness index, degree of obesity, area of visceral obesity, abdominal obesity were estimated by InBody 720 body composition analyser. We collected data on students’ eating habits, alcohol, drug and smoking consuming habits, and daily fluid intake, self-reported health status and physical self-concept by using questionnaires.

Based on the body mass index, 72% of the examined students had normal nutritional status, 4% were undernourished, 12% were overweight and 5% were obese. It is an interesting data that students’ subjective perceptions of their own nutritional status differed from the measured values, as 44% of them considered themselves overweight or obese. One-third of people having normal nutritional status considered themselves overweight or obese, 70% of those who were actually overweight considered themselves overweight, nearly 30% considered obese and half of those who were truly abnormally obese considered themselves only slightly overweight, and the other half estimated their nutritional status realistically. 22% of students admitted to dieting mainly (81%) to reduce their weight. 65% of dieters had normal nutritional status, 32% are overweight or obese and 3% were undernourished. In terms of body fat percentage, 42% of examined participants were in the normal category, 42% were overweight, 12% were obese and 5% were too lean. In terms of visceral fat 72% of students were in the normal category, 13% were in high and 14% were in critical category for health risk. The distribution of students’ fitness index indicated that their physical activity was insufficient, 46% of them did not reach the average (normal) fitness value. The research results revealed that one-third of students should move toward a healthier, more conscious, more active lifestyle.
“Trabalho com fome entregando comida todos os dias”

Published: January 2023

Este relato propôs uma análise de aspectos da violação do Direito Humano à Alimentação Adequada (DHAA) a partir de experiências de entregadores de aplicativos relacionadas à alimentação no município de São Paulo, retratadas em materiais jornalísticos na pandemia de COVID-19, publicados até setembro de 2020. Este trabalho se configurou como estudo de caso em uma disciplina de graduação em Nutrição, por meio de um projeto com foco em situações de desigualdade e vulnerabilidade. Foram selecionados materiais com registros de práticas e/ou demandas alimentares dos entregadores associadas às atividades trabalhistas. O conteúdo foi discutido através da definição do DHAA, considerando recomendações do Guia Alimentar para a População Brasileira e discussões da sociologia do trabalho. Como resultados, aspectos de violação do DHAA foram notados para a garantia ao acesso a alimentos em quantidade e qualidade, com grande consumo de ultraprocessados; práticas alimentares inadequadas no que concerne ao ato de comer e à comensalidade, com preponderância da necessidade de “matar a fome”; e a inserção dos entregadores em um sistema alimentar injusto no âmbito das relações trabalhistas e insustentável em aspectos ambientais e de saúde. Por meio do reconhecimento das circunstâncias de fome e de demandas apresentadas pelos entregadores, esta análise ressaltou o potencial humanizador da alimentação em estimular reivindicações, especialmente no contexto pandêmico e de retirada de direitos trabalhistas, além de destacar a necessidade de construir condições de trabalho, em conjunto a políticas públicas que mitiguem a fome e injustiça, com vistas à promoção de ambientes e sistemas alimentares saudáveis.

Globally, more than 4.3 million confirmed cases and more than 2,90,000 fatalities occurred due to the COVID-19 disease outbreak, which profoundly affected the entire planet. This has also fanned fears of a forthcoming economic collapse and recession. This type of event is referred to as a "black swan" because it adds unexpected and unique aspects to the economic environment and has the potential to start a chain of unfavourable reactions and market disruptions. As a result of social isolation, self-isolation, and travel restrictions, there has been a drop in the labour force across all economic sectors, resulting in the loss of several jobs. In addition, due to the closing of schools, demand for commodities and manufactured goods has decreased. On the other hand, the need for medical supplies is expanding rapidly. Through the end of 2019, the five primary economic sectors generated money and employment. Early in 2020, however, these industries encountered a major economic and employment crisis due to the COVID-19 outbreak. The COVID-19 outbreak has greatly affected the economic and social conditions of the nation, particularly regarding these five core economic activities. This study's objective is to examine the effects of COVID-19 on the agriculture, manufacturing, construction, services, mining and quarrying sectors. To achieve this purpose, this study employed descriptive analysis to examine performance data encompassing 10 years (2012 - 2021). The findings indicate that the COVID-19 epidemic has a substantial and negative impact on the Malaysian economy.

Highlights1. Diabetes mellitus is a category of metabolic disease characterized by uncontrolled hyperglycemia.2. This study revealed no statistically significant differences in total cholesterol, TG, LDL, HDL, or LDL/HDL ratio between amputated and non-amputated DFU patients.
AbstractBackground: Diabetic foot ulcers (DFU) are microvascular and macrovascular consequences of diabetes and are associated with neuropathy, vascular disease, and immunosuppression. Increased blood glucose levels may result in the glycosylation of proteins in the nerve cells of the foot, leading to ischemia and cellular disturbances that can damage muscular, sensory, and autonomic neurons. Objective: To compare the lipid profiles of amputated and non-amputated DFU patients. Material and Method: This was a cross-sectional, analytic, retrospective research using total sample approach to analyze the medical records of all diabetes patients admitted to Dr. Soetomo General Academic Hospital between February 2018 and December 2020, with or without amputation. Result: The average age of DFU patients at Dr. Soetomo General Academic Hospital was 55.6 9.4 years, and the majority of patients were female (57%). Diabetic foot ulcers were most prevalent in the age group ≥50 years old (74%), amputated DFU patients had larger mean total cholesterol, TG, LDL, and HDL than non-amputated DFU patients, although the difference was not statistically significant. While the mean LDL/HDL ratio was greater in non-amputated DFU patients, the difference was statistically insignificant. The HDL level was low in 84% of amputated DFU patients, whereas in non-amputated DFU patients it was 81%. Conclusion: This research showed no significant variation in total cholesterol, TG, LDL, HDL, or the LDL/HDL ratio between amputated and non-amputated DFU patients. Most DFU patients with and without amputations had low HDL values.

Published: January 2023

Experiments were performed to determine the effects of ascorbic acid on haematological and water quality parameters of Clarias gariepinus subjected to road transportation. A total of 40 apparently healthy adult Clarias gariepinus of an average weight of 450.46 ± 23.06 g and an average length of 38. 23 ± 4.46 cm were used for the experiment and were divided into two groups. Group I (AAF) was administered ascorbic acid daily for one month and on the day of transportation while group II (NAF) was not administered. After transportation of the erythrocyte counts, packed cell volume was significantly higher in group I (P < 0.05). Total leucocyte count, neutrophil count, and neutrophil/lymphocyte ratio of group I were significantly lower (P < 0.05) in group I compared to group II. The concentrations of nitrite, nitrate, and ammonia were significantly higher (P < 0.05) in group II compared to group I post-transportation. The dissolved oxygen content of group I was however higher (P < 0.05) in group I compared to group II. It was therefore concluded that ascorbic acid modulated some haematological and water quality parameters of Clarias gariepinus and may be beneficial to the fish in ameliorating the stress of transportation.
The Potentials of Ergothioneine in the management of diseases in animals
Authors: Adah Adakole
Published: January 2023

The amino acid histidine is the source of the special nutraceutical ergothioneine (ERG), which is a potent antioxidant. Higher plants and animals, who obtain it from the soil and their food, respectively, do not synthesize it; instead, they obtain it through particular microorganisms, such as actinobacteria and mushrooms. Solute carrier family 22, member 4 (SLC22A4), sometimes referred to as organic cation transporter novel type-1 is an incredibly selective transporter for the substance that is only present in animals (OCTN-1). Depending on how OCTN 1 is expressed in different tissues, particularly in those that are more susceptible to oxidative stress, such as erythrocytes, the buildup of ERG differs. ERG concentration is decreased in a number of chronic inflammatory illnesses, and it appears to have potent cytoprotective actions.It has been certified to be relatively safe by regulatory authorities compared to many other antioxidants.

A rövid ellátási láncok a nemzetközi tanulmányok egyre gyakrabban vizsgált területének számítanak. Sokan elterjedésükben látják a fenntarthatóság megoldását a mezőgazdaságban. Egyik meghatározó értékesítési csatornái a termelői piacok, melyek száma nagyot ugrott az utóbbi években Magyarországon. A termelői piacok fogyasztóit világszerte számos tanulmány elemzi, azonban az egyetemisták termelői piaccal való kapcsolatát kevés kutatás vizsgálja. Az USA-ban azonban akadnak erre példák; sőt az is jellemző, hogy termelői piacokat rendeznek az egyetemi campusokon. Az egyetemisták nem tipikus vásárlói a termelői piacoknak, azonban ők lesznek a jövő fogyasztói, így érdemes megvizsgálni az ő szokásaikat, igényeiket is. Egyetemisták által kitöltött kérdőív segítségével megvizsgáljuk, hogy mutatkozik-e különbség a korábbi tanulmányokban vizsgált és az általunk elemzett egyetemisták élelmiszervásárlási szokásai között. Vannak-e egyértelműen azonosítható termelői piacra járási szokásaik? Van-e igény termelői piacok rendezésére az egyetemek campusán? A Magyarországon tanuló egyetemisták élelmiszervásárlási szokásai jórészt megegyeznek a korábban végzett kutatások által vizsgált egyetemisták szokásaival. Egyetemi hallgatóknál az élelmiszervásárlás során főként a termékek ára, a kényelem, a választék és a minőség szempontok dominálnak. A kérdőívet kitöltő egyetemisták 31%-a még soha nem vásárolt termelői piacon, és csupán 21%-a vásárol rendszeresen.  A rendszeresen nem vásárlók legfőbb akadálya a termelői piacoktól való távolság, amire megoldást jelenthet a termelői piacok egyetemi campuson történő megrendezése. A tanulmányban vizsgált minta 95%-a nyitott erre, így érdemes lenne egy-egy egyetem tekintetében külön kutatást végezni és a pozitív eredményeket gyakorlatba is átvezetni.JEL-kódok: O13, P46, Q13

INVESTIGATIONS OF THE TRANSPORT POSSIBILITIES OF A NEW VIBRATORY CONVEYOR EQUIPPED WITH A SINGLE ELECTRO-VIBRATOR
Authors: ŻMUDA Weronika , CZUBAK Piotr
Published: January 2023

In the present study, a new vibratory conveyor (patent pending) equipped with a single electro-vibrator intended for an accurate material dosage is investigated. The possibilities of material transportation in the circum-resonant zone were investigated analytically and by simulations [1]. Furthermore, the dependencies of the transport velocity of the tested conveyor as functions of the excitation frequency were determined. Favorable excitation frequencies at transports in the main and reversal directions were found, and the high usefulness of the machine in the production lines requiring accurate material dosage was indicated. A control strategy allowing for a sudden stop of the transported material was also proposed.

As electric drives slowly replace passenger cars and light special vehicles, electric drives in the heavy-duty road sector have started to emerge. As for off-road vehicles, there is some effort to reduce the amount of fossil fuel used. In this study, the series hybrid application for a heavy-duty tractor is investigated. Work conditions are described using modified worldwide transient vehicle cycle to evaluate the efficiency of an energy management system applied, as well as the overall vehicle performance and efficiency. As a result, in some test scenarios, smaller-than-expected energy outputs were identified and new ways to improve energy management were found.
Aldo van Eyck en La Haya: reinterpretación espacial de la iglesia católica: luz y dualidad = Aldo van Eyck in The Hague: Spatial reinterpretation of the Catholic Church: Light and duality
Authors: Fernández-Llebrez Muñoz José
Published: January 2023

AbstractThe Pastoor Van Ars Catholic church represents one of the most brilliant and somewhat unknown projects of Aldo van Eyck. A research stay at the TU Delft Faculty of Architecture allowed to visit and study the building in detail and to consult the three archives that describe it (Bishopric of Rotterdam, Municipal Archive of The Hague and Aldo+Hannie van Eyck Foundation) with the purpose of getting access to the graphic documentation as a whole —mostly unpublished— and being able to develop a well-argued architectural interpretation and criticism. In this sense, in parallel to the progressive description and understanding of the building, the paper relates the architectural design of Pastoor Van Ars with some of the essential concepts of van Eyck’s theoretical discourse, such as the twin phenomena or the principle of relativity, as well as with a unique and thorough treatment of natural light.ResumenLa iglesia católica Pastoor Van Ars representa uno de los proyectos más brillantes y en cierto modo desconocidos de Aldo van Eyck. Una estancia de investigación en la Escuela de Arquitectura de la Universidad de Delft permitió visitar y estudiar de manera pormenorizada el edificio y consultar los tres archivos que lo describen (Obispado de Róterdam, Archivo Municipal de La Haya y Aldo + Hannie van Eyck Foundation) con el propósito de acceder al conjunto de la documentación gráfica del proyecto —mayoritariamente inédita— y poder abordar una interpretación y crítica arquitectónica argumentadas. En este sentido, en paralelo a la progresiva descripción y comprensión de la obra, el artículo relaciona la solución arquitectónica de Pastoor Van Ars con algunos de los conceptos esenciales del discurso teórico de van Eyck, como el fenómeno dual o el principio de relatividad, así como con un singular y meditado tratamiento de la luz natural.
Assembly Sequence Optimization of Spatial Trusses Using Graph Embedding and Reinforcement Learning
Authors: Hayashi Kazuki , Ohsaki Makoto , Kotera Masaya
Published: January 2023

We consider a truss as a graph consisting of nodes and edges, and combine graph embedding (GE) and reinforcement learning (RL) to develop an agent for generating a stable assembly path for a truss with arbitrary configuration. GE is a method of embedding the features of a graph into
a vector space. By using GE, the agent can obtain numerical information on neighboring members and nodes considering their connectivity. Since the stability of a structure is strongly affected by the relative positions of members and nodes, feature extraction by GE should be effective in considering
the stability of a truss. The proposed method not only can train agents using trusses with arbitrary connectivity but also can apply trained agents to trusses with arbitrary connectivity, ensuring the versatility of the trained agents' applicability. In the numerical examples, the trained
agents are verified to find rational assembly sequences for various trusses more than 1000 times faster than metaheuristic approaches. The trained agent is further implemented as a user-friendly component compatible with 3D modeling software.
Matter as Pure 'Atoms' of Electricity
Authors: Kirimi Misheck
Published: January 2023

Dirac’s equation depicts electron mass as either positive or negative. Taken as correct description of nature, the equation identifies electron mass as ‘electrically active’ and therefore fundamentally different from the ordinary, ‘electrically passive’ mass. Following this cue, I demonstrate that electron mass (me) is the natural elementary mass: positive (me+) and negative (me–) elementary masses neutralise to an elementary unit of the electrically passive mass (2me0). Further, I show that electron mass (me± ) and the electrostatic field (ef±) surrounding it compose an elementary charge (e±), thereby relating charge to mass. Two plain principles underlie these findings. 1) Electric charge and gravitational mass have a common root: positive (e+) and negative (e–) charges coexist as neutral charge (2e0), which is the quantum of gravitational mass. 2) Charge is a static (nonrelativistic) ‘atom of electricity’ and obeys the laws of electrostatics; electron is the same ‘atom of electricity’ at ultrahigh (relativistic) speed and obeys the laws of electrodynamics. That is, charges are electricity at rest; electrons are electricity in motion – ‘same physical entities two behavioural identities.’ A decisive proof that this paradigm shift correctly portrays is that it verifiably unifies Newton’s law of gravity and Coulomb’s law of electrostatics to: 8G/mpme = K/e2; where G and K are the respective constants, mp the proton mass, me the electron mass, and e the elementary charge. Ultimately, the insights simplify matter to pure ‘atoms’ of positive and negative electricity.

Background: Infant mortality is one of the sensitive indicators to know the degree of health of a country and even to measure the level of progress of a nation. The Low Birth Weight Babies (LBW) are the highest cause of infant mortality in Depok until it reaches 81 cases in 2019. One of the efforts made by public health office to reduce the infant mortality rate is to use Kangaroo Mother Care. This research aims to analyze the implementation of Kangaroo Mother Care Program in public health center in Depok, Indonesia. 

Methods: The method of study is qualitative with purposive sampling approach.

Result: The results showed that the informants were not aware of the existence of Mayor Regulation Number 89 year 2020 regarding Kangaroo Method Care. Health workers do not yet have sufficient knowledge about the implementation of the Kangaroo Method of Care. The implementation of the Kangaroo Method of Care is still not supported by complete facilities. Human Resources is also still inadequate.

Conclusion: The conclusion of this research is the Kangaroo Method Care program has not run optimally. There needs to be an effort to improve the implementation of the Kangaroo Method Care program at the public health center.

Published: January 2023

Background: Adolescent women will experience puberty which is marked by the occurrence of menstruation. During menstruation, adolescents will experience problems such as menstrual pain or dysmenorrhea. The aim of this study was to determine the relationship between consumption patterns and nutritional status with adolescent dysmenorrhea.

Method: This study uses an analytical survey design with a cross sectional approach. Subjects were selected by purposive sampling, namely adolescent girls’ class XI MIPA 1-4, totaling 84 people. Data were analyzed using Pearson's test to determine the significance of the relationship between consumption patterns and nutritional status to adolescent dysmenorrhea.

Result: This study showed a significant relationship between nutritional status and the incidence of dysmenorrhea in class XI students at SMA Negeri 2 Toraja Utara (p<0.05; r=0.0224). In addition, this study did not find any relationship between the level of energy and carbohydrate adequacy with the incidence of dysmenorrhea (p>0.05). The results of the statistical test showed r = -0.039, which means that there is a weak relationship in a negative direction between the incidence of dysmenorrhea and the frequency of carbohydrate consumption, and p = 0.726, which means that there is a relationship but not significant. This study also shows the results of statistical tests r = -0.036 and p = 0.743, which means that there is a weak and insignificant relationship between the incidence of dysmenorrhea and the frequency of consumption of caffeine sources.

Conclusion: Based on the research that has been done, it can be concluded that the incidence of dysmenorrhea in most respondents is in the moderate level category and the nutritional status of respondents is generally in the normal category.

Published: January 2023

Background: One of the health facilities provided by the government is integrated health center in the village or Pos Pelayanan Terpadu or Posyandu. The impact of  posyandu that does not run smoothly will result in a decline in the quality of public health. The purpose of this study is to provide an overview of the factors that influence the implementation of posyandu in Kaliboto Lor Village, Jatiroto District, in 2020.

Method: The research was carried out with descriptive observation and also qualitative design. The sampling technique used is snowball sampling with a total sample of 6 people. The research was conducted from October to November 2021.

Result: The research found that the implementation of posyandu in Kaliboto Lor Village, Jatiroto District could not be carried out every month due to restrictions on activities and the application of health protocols. There are supporting factors, including parties’ participation, infrastructure facilities, good coordination, the existence of coaching, and evaluation of activities. Inhibiting factors include non-optimal use of the forum, limited posyandu targets, lack of commitment from parties, and an unsupportive environment. The efforts made are counseling, home visits, appointments, and monitoring of periodic evaluations. There is no significant difference between the implementation of posyandu with the previous year.

Conclusion: In general, the implementation of posyandu is still not optimal due to the constrained method and the need for a follow-up plan from the puskesmas. The research results obtained can be used as a reference in improving the performance of posyandu.
