Impact of Oxytocin Massage for Postpartum Mothers on Breast Milk Production
Authors: Umamity Syafitrah , Fitriasari Endah Fitriasari , Umasugi Muhammad Taufan
Published: November 2024

Introduction Mother's Milk is a divine gift explained in the Quran, Surah Lukman verse 14, which recommends mothers to breastfeed their children for a full two years. Breast milk is considered the best source of nutrition for infants, especially within the age range of 0–6 months. However, not all breastfeeding mothers can easily produce breast milk directly, as the process involves a complex interaction influenced by the hormone oxytocin. This study aims to assess the impact of applying oxytocin massage on breast milk production in postpartum mothers in the Working Area of Waimital Community Health Center, Kairatu District, West Seram Regency. The research design used is quasi-experimental, with sample selection using non-probability sampling involving 20 respondents. The research instrument used a questionnaire, and data analysis was conducted using the Mann-Whitney test and Wilcoxon test to evaluate changes before and after the intervention for each variable. The bivariate analysis results based on the treatment group variable showed the highest P-value at 0.008 and the lowest at 0.003 (< 0.05), while in the control group, the highest P-value was 0.157 and the lowest was 0.083 (< 0.05). Thus, it can be concluded that the application of oxytocin massage has a highly significant effect on breast milk production in postpartum mothers in the treatment group.

Published: November 2024

Alarm rationalization is a critical process in engineering projects, focusing on optimizing alarm management systems to enhance operational efficiency, reduce costs, and improve safety. This paper explores how alarm rationalization, when implemented effectively, mitigates alarm fatigue, reduces unnecessary alerts, and ensures that operators are only notified of critical issues. By analyzing cost-saving measures and efficiency gains, the study highlights how rationalization techniques can streamline decision-making and improve system reliability across various industries, such as oil and gas, manufacturing, and chemical processing. The rationalization process involves reviewing existing alarm systems, identifying redundant or non-critical alarms, and reclassifying alarms based on priority and operational impact. By refining alarm settings, engineers can decrease operator workload and minimize downtime, contributing to significant cost savings. For example, reducing nuisance alarms not only improves response times but also extends the lifespan of equipment by preventing unnecessary shutdowns. From a global perspective, the adoption of alarm rationalization varies by industry and region, with some sectors benefiting from advanced automation technologies and standardized regulatory guidelines. The implementation of intelligent alarm systems, combined with data analytics and machine learning, further enhances the ability to predict and prevent failures before they escalate into major operational disruptions. This paper also examines case studies of successful alarm rationalization projects, demonstrating tangible efficiency gains such as reduced maintenance costs, improved safety, and optimized production processes. Additionally, the discussion extends to the challenges and best practices in alarm rationalization, such as securing stakeholder buy-in, aligning rationalization efforts with organizational goals, and ensuring compliance with international safety standards. In conclusion, alarm rationalization offers engineering projects an effective pathway to achieve cost efficiency and operational excellence. However, the success of these initiatives depends on robust planning, continuous monitoring, and the integration of advanced technologies.

The Repo Market and Conflict Inflation
Authors: Marshall Wesley
Published: November 2024

This article seeks to connect today's inflation with one of the least studied and understood creations of the Federal Reserve - the repurchase (repo) market. Despite decades of existence, it is only in the last few years that the repo market has ceased to function smoothly, experiencing first a moment of crisis followed by one of great profitability. When functioning properly, the repo market went virtually unnoticed. Now that it is not, the market has gained the attention of mainstream economics as well as policy makers. However, conventional academic analysis is limited and cannot fully capture the effects that the repo market has had on the overall economy. In this article, we argue that the causes of the pandemic inflation and its public policy response can be understood as the culmination of the longer term currents of globalized financialization and central bank independence. To sharpen our focus on the shorter term, we construct upon the heterodox position of conflict inflation, and argue that the repo market and its principle actors should be considered within the discussion.
The Dynamic Post COVID-19 World and Inflation: is Nigeria’s Monetary Policy Effective?
Authors: Erediauwa Adesuwa , Olawoye Salewa
Published: November 2024

Nigeria had relative success in tackling the Covid-19 and its attendant economic consequences. A complementary mix of superior monetary and fiscal policy interventions saw support for the real sector, as well as growth and strengthening for the financial sector. The monetary authorities used several mediums to inject funds into the economy, while the financial sector was the channel through which huge sums were injected into the economy. These interventions however came with their fair share of woes, as they were carried out against the backdrop of rising inflation and unemployment levels. The unique nature of the Nigerian economy saw policy interventions targeted at stabilizing the economy, yield less than satisfactory outcomes. Currently, Nigeria faces the lagged impact of monetary and fiscal Covid-19 interventions in persistent high double digit inflation rates. The fall in global oil supply and world food prices necessitated by the Ukraine-Russian war have not helped the situation. These global events have had far reaching impacts on the Nigeria economy via the shortfall in supply of Premium Motor Spirit (PMS) products, food shortages, and resultant exchange rate pressures. The domestic economy has not been without its fair share of events that have resulted in a spike in inflation rates. The persistent security issues in the north and other parts of Nigeria, did not serve as an obstacle to people mobilization and the high spending during the 2023 elections. Declining government revenues, the rising public debt and its servicing, while inimical in their own stead, have catalyzed the pressure on the exchange rate. Against these backdrop, the monetary authority’s decision to institute a currency redesign and cashless policy has left people confused as to what actually is their short- and long-term goals/objectives, the effectiveness of policy to achieve said goals, as well as their readiness to tailor policy to changing global events/trends. The study will seek to examine monetary authority responses to curb inflation and achieve economic stability.
The Weight Of Silence: ‘Trauma’ And Its Echoes In Selvadurai's Selective Queer Narratives
Authors: Shikha Smriti , Vaidya Prof. Dr. Manjiree
Published: November 2024

Trauma refers to a deeply distressing and disturbing experience that overwhelms an individual’s ability to cope and results in feelings of intense fear, helplessness, or horror, leading to the symptom of long-lasting anxiety, depression, post-traumatic stress disorder and other kind of psychological distress and making an individual question their identity, impacting their sense of self, their relationships, and their mental and emotional health. Queer theory is employed as a theoretical framework to emphasize that trauma is not solely an individual problem but rather a product of societal and cultural factors, including homophobia, transphobia, and heteronormativity. The concept of intersectionality recognizes that individuals can experience multiple forms of discrimination, and this is especially true for Queer individuals who face a unique set of challenges in society. The question of how Queers experience trauma requires examining power dynamics and the ways in which voices and experiences of such individuals are recognized and valued within society. Despite this, there has been limited research on the discussion on Trauma of a Queer individuals and its impact on their self and society. This research paper explores the confluence of queer theory and trauma theory, shedding light on how conventionalism and expectations related to gender and sexuality contribute to exclusive formation of identity of LGBTQ+ individuals against the heteronormative rhetoric while investigating the traces in Selvadurai’s writings. Secondly, it attempts to create space for Queer individuals to speak out and be heard, while also recognizing and addressing the structural barriers that limit their agency and power. Lastly, this research paper aims to highlight the ways in which experiences of trauma can be transformative and serve as a catalyst for change, leading to new and more inclusive understandings of gender and sexuality.
(DES) COORDINACIÓN DE LA OFERTA: OBSERVACIÓN DE ESTRATEGIAS PARA ABORDAR LA VIOLENCIA EN EL POLOLEO CON JUVENTUDES DE PUERTO AYSÉN
Authors: Madrigal Calderón Johanna , Peña Oyarzún Matías , Urquieta Alvarez María Antonieta
Published: November 2024

El presente artículo tiene como objetivo observar -desde una mirada sistémica a la intervención- la relación entre las características de la violencia en el pololeo que identifican juventudes de la ciudad de Puerto Aysén y la oferta estatal para abordar el fenómeno, apreciándose brechas entre lo que las juventudes relevan, las estrategias de intervención existentes y el conocimiento que tienen este grupo etario respecto de las mismas. Los debates que se exponen se basan en un estudio sobre caracterización de la violencia en el pololeo con estudiantes de cuatro establecimientos de educación media de Puerto Aysén y en cuyos resultados se destaca la importancia que dan estas juventudes a la expresión de este tipo de violencia en las dimensiones psicológica, física y cibernética junto con el desconocimiento de esta población respecto de la oferta de intervención en esta temática, la que -además- aborda de manera indirecta esta violencia, es decir, falta una oferta que se focalice en violencia en el pololeo en específico y, más aún, en adolescentes y que conjugue su visión respecto de la violencia en el pololeo. En este sentido, se aprecia una descoordinación sistémica de las expectativas de los sistemas que buscan intervenir y los (potenciales) intervenidos.
EVALUACIÓN DEL MODELO DE INTERVENCIÓN DE CAMPAMENTOS: BARRIO TRANSITORIO LA CHIMBA – ANTOFAGASTA 2022
Authors: Stevenson Valdés Alejandra , Martinic Castro María José
Published: November 2024

En 2022 Fundación Recrea (FR), convoca a un equipo de investigadores externos para sistematizar y evaluar el modelo de intervención Barrio Transitorio (MIBT), desarrollado por 7 años en el sector de la Chimba- Antofagasta, que es una alternativa probada, evaluada y modelada para intervenir campamentos y familias que viven en ellos. La indagación bajo la metodología de evaluación realista busca desentrañar la formula: Contexto + Mecanismo = resultado (CMO), para entender qué, cómo, para quién y en qué contexto funciona el modelo barrio transitorio que ejecuta la Fundación. El proceso se inició con la elaboración de la teoría del cambio, identificando los mecanismos o caminos de transformación, para luego contrastar esta teoría con la realidad. Para ello se elaboraron instrumentos basados en la técnica ‘del cambio más significativo’, para recoger de la voz de los propios beneficiarios, cuáles eran las renovaciones experimentadas entre vivir en un campamento y un BT. A partir de los resultados de esta evaluación se conceptualizaron los atributos y componentes del modelo en su propuesta de diseño urbanístico y de intervención social y, los principales resultados obtenidos de la intervención, dentro de los cuales se constata una vida con menos vulneración de derechos, sintiéndose parte de una comunidad e insertos en el sistema de protección social. La transitoriedad termina cuando obtienen su vivienda definitiva mediante el subsidio habitacional.

Published: November 2024

Конское снаряжение по праву считается одной из основных категорий так называемой скифской триады и является ключевым элементом всаднической культуры, материальная база которой существенно пополнилась в ходе исследований последних десятилетий. Соответственно, на повестке дня — осмысление собранных данных, анализ проблем эволюции и трансформации конской амуниции раннего железного века с основой на типологический метод научного познания. Объектом данного исследования является уздечный и седельный комплексы и его составные элементы, развитие которых берёт своё начало в эпоху бронзы и уже в раннем железном веке характеризуется поиском наиболее оптимальных в функциональном отношении вариаций использования. В статье вводятся в научный оборот материалы, обнаруженные на окраине с. Горная Маевка (Кыргызстан). Уникальность их заключается в новом способе соединения удил и псалиев. При сравнительно-типологическом анализе всех находок выявлен круг наиболее близких по морфологическим и техническим характеристикам аналогий, анализ которых в определённой степени указывает на принадлежность к раннесакскому обществу. Авторы также представили типологию способов соединения удил и псалиев. На основе приведённых хронологических показателей этот комплекс предварительно датирован в рамках VIII— VII вв. до н.э.

Horse equipment is considered to be one of the main categories of the so-called “Scythian triad” and is a key element of the equestrian culture, the material base of which has been significantly replenished in the course of research in recent decades. Accordingly, the agenda includes comprehension of the collected data, analysis of the problems of evolution and transformation of horse ammunition of the Early Iron Age, based on the typological method of scientific knowledge. The object of this study is the bridle complex and its constituent elements, the development of which originates in the Bronze Age and already in the Early Iron Age is characterized by the search for the most optimal functional variations of use. The article introduces for the first time into scientific circulation the materials discovered on the outskirts of the village of Gornaya Mayevka (Kyrgyzstan). The uniqueness of this material lies in a new way of connecting rods and psalms. A comparative typological analysis of all the finds revealed a range of analogies closest in morphological and technical characteristics, the analysis of which to a certain extent indicates belonging to the Early Saka society. The authors also presented a typology of ways to connect bits and bit hoops. Summing up all the chronological indicators given, this complex is tentatively dated within the framework of the 8th—7th centuries BC.
КЕРАМИЧЕСКИЙ КОМПЛЕКС МОГИЛЬНИКА КЕМПИРТАС
Authors: С.Ж. Рахимжанова , Е.К. Тушева
Published: November 2024

В публикации в научный оборот вводится керамический комплекс могильника Кемпиртас. Технологический анализ керамики проведён в рамках историко-культурного подхода к изучению древнего гончарства, разработанного А.А. Бобринским. Исследование показало, что для изготовления посуды использовали среднеожелезнённые слабозапесоченные глины (100%), а в результате изучения степени запесоченности глин и состава естественных минеральных примесей было выявлено два «места» добычи исходного пластичного сырья. Анализ формовочных масс позволил выяснить, что самым массовым рецептом являлся «глина + дресва из прозрачного и молочного кварцита + органический раствор» (88,2%), что говорит об однородности населения, оставившего данный памятник. Таким образом, анализируя традиции выбора исходного сырья и составления формовочных масс, а именно высокую степень их единообразия, возможно предположить, что население было родственным. Сосуды горшечной и баночной форм отмечены в одинаковом количестве (по 46,7%). Анализ орнаментации позволил выявить две традиции декорирования посуды — гребенчатой и гладкой. Материалы могильника Кемпиртас входят в круг погребальных объектов алакульской (атасуской) культурно-исторической общности Северной Сарыарки.

The publication introduces the ceramic complex of the Kempirtas burial ground into scientific circulation. Technological analysis of ceramics was carried out within the framework of the historical and cultural approach to the study of ancient pottery, developed by A.A. Bobrinsky. The study showed that for the manufacture of dishes, medium-ferruginous, slightly sandy clays (100%) were used, and as a result of studying the degree of sandiness of the clays and the composition of natural mineral impurities, two “places” for the extraction of initial plastic raw materials were identified. Analysis of the molding masses made it possible to find out that the most widespread recipe was “was clay + clear and milky quartzite crushed mineral + organic solution” (88.2%), which indicates the homogeneity of the population that left this monument. Thus, by analyzing the traditions of choosing raw materials and composing molding compounds, namely their high degree of uniformity, it is possible to assume that the population was related. The vessels of open and closed rims are noted in the same quantity (46.7% each). Analysis of the ornamentation made it possible to identify two traditions of decorating tableware — comb and smooth. The materials from the Kempirtas burial ground are included in the circle of burial objects of the Alakul (Atasu) cultural and historical community of Northern Saryarka.

В статье публикуются результаты исследования раннетасмолинского захоронения из Центрального Казахстана. Полученный материал представлен украшениями в виде золотых серёг, подвески и каменных бус. Обнаружение в насыпи кургана зернотёрки и курант поднимает вопрос о ведении подсобного земледелия кочевым населением в раннем железном веке. Проведены половозрастные определения человеческих останков, трасологический анализ терочного механизма, определены породы каменных изделий. Радиоуглеродный анализ позволил датировать исследованное сооружение в рамках середины VIII — конца VI в. до н.э., что согласуется с типологическими аналогиями обнаруженных в захоронении золотых серег.

Thе article contains the materials of research of the Early Tasmola burial in Central Kazakhstan. The obtained material is represented by jewelry in the form of gold earrings, pendants and stone beads. The discovery of a grain grinder and a grindstone in the mound raises the question of secondary farming by the nomadic population in the Early Iron Age. Age and sex determinations of human remains, trace analysis of the grinder mechanism, and the rocks of stone products were determined. Radiocarbon analysis allowed to date the investigated construction within the framework of the middle of 8th — end of 6th centuries BC. This agrees with the typological analogies of gold earrings found in the burial.

Изучение и реконструкция различных видов воинских атрибутов (знамен, бунчуков, флагов, их особенностей и форм) золотордынского периода (эпохи Улуса Джучи) является сегодня одной из актуальных научных проблем. До сих пор эта тема не была предметом отдельного исследования в научных работах по истории Золотой Орды. Поэтому целью данного исследования является востановление системы военных символов золотоордынского времени. Основным источником для исследования послужили иконографические материалы. Использовались памятники изобразительного искусства стран и народов, входивших в состав Империи Чингисхана и его наследников, а также стран, которые были в культурном и военном контакте с Улусом Джучи. Дополнительными источниками послужили сведения из письменной литературы, а также археологические и вещественные материалы. Подробный и углубленный анализ данных всех этих источников позволил восстановить использовавшийся комплекс военной символики Золотой Орды (Улуса Джучи), определить разнообразные виды знамен, флагов и бунчуков этого периода, различающиеся формой полотнища и дополнительными элементами, определяющими их статус и особенности их назначения.

The study and reconstruction of various types of military attributes (banners, horsetail bunchuks, flags, their features and forms) from the period of the Golden Horde (the Ulus of Jochi era) is currently one of the pertinent scientific problems. This topic has not previously been the subject of independent research in studies on the history of the Golden Horde. Therefore, the aim of this research was to reconstruct the existing system of military symbols from the Golden Horde period based on historical sources. The primary source for the study was iconographic materials. Monuments of visual art from the countries and peoples that were part of the Empire of Genghis Khan and his successors, as well as from countries that had cultural and military contact with the Ulus of Jochi, were utilized. Additional sources included information from written literature, as well as archaeological and material evidence. A detailed and in-depth analysis of the data from all these sources enabled the reconstruction of the complex military symbolism used during the Golden Horde era (Ulus of Jochi), and the identification of various types of banners, flags, and bunchuks of this period, which differed in the shape of the canvas and additional elements determining their status and specific purposes.

The COVID-19 pandemic has created significant disruptions in teaching and learning at universities, predisposing university students to develop mental health issues which may impact their academic experience. This study evaluated the academic experience and mental health status of students enrolled in Health Science courses at Swinburne University of Technology via a mixed-methods cross-sectional survey conducted on 36 students (18+ years). Out of these students, 10 attended in-depth interviews. Results obtained from both quantitative and qualitative data analyses found high levels of stress, anxiety and depression, with more than 50% experiencing levels above the clinical thresholds. About 39% of the participants reported feeling able to concentrate on their learning when materials were delivered via an online mode. Students’ engagement through online learning was significantly disrupted, 97.2% of the respondents found it difficult to perform group work and 75% reported not being able to engage with their peers. Higher levels of stress, anxiety and depression were significantly associated with a compromised learning experience. Spearman’s Rank Correlation showed a significant negative association between stress and students’ engagement with online learning (Spearman’s rho=-0.49, p=0.003). Supporting the learning experiences along with monitoring the mental health of all university students should be of high priority for university authorities.
Polihidruros de cobre: Una poderosa herramienta en síntesis química. El reactivo de Stryker en perspectiva
Authors: Contreras Ricardo
Published: November 2024

El reactivo de Stryker, octaedro-hexa-µ3-hidrohexaquis(trifenilfosfina-kP)hexacobre(I), [(Ph3P)CuH)]6, reportado por el Grupo de Osborn en 1971, y sistemáticamente estudiado en sus aplicaciones químicas desde 1988 por Jeffrey M. Stryker, constituye una poderosa herramienta en la síntesis química de sustancias que tienen alto valor para la química fina. Desde sustancias con propiedades farmacológicas hasta llegar a compuestos de interés en catálisis, agroquímica, ciencia de materiales o nanoquímica, el reactivo de Stryker, catalogado en 1991 como “reactivo del año”, y todos sus polihidruros análogos, ofrecen grandes oportunidades para desarrollar protocolos de síntesis one-pot basados en una gran varie-dad de fosfinas quirales sintetizadas en las últimas décadas. A partir de los resultados obtenidos en la revisión que se ha realizado, se puede concluir que el reactivo de Stryker ha dado impulso a la investigación de cúmulos polihidruros de cobre(I) de alta nuclearidad, brindando nuevas oportunidades de investigación en síntesis orgánica y asimétrica o en el campo de la química inorgánica y organometálica.

La modificación química de los almidones es un procedimiento ampliamente utilizado. En este estudio se realizó la esterificación del almidón extraído de las semillas de aguacate (Persea americana), se caracterizó y se utilizó para obtener un bioplástico por el método de fundición. Para ello se utilizaron tres plastificantes: alcohol polivinílico, glicerol y sorbitol; además de agua y una solución de NaOH al 15% (m/v). Se realizaron 27 formulaciones preliminares para verificar la formación de bioplástico y a partir de allí, se tomó como unidad experimental 5 g de almidón, 4 mL de agua destilada, 4 mL de solución de NaOH y 2 g de plastificante. Al caracterizar el bioplástico, se determinó que los mejores resultados en cuanto a humedad y permeabilidad al vapor de agua se obtuvieron en el material donde se utilizó sorbitol, con 5% y 397,80 g/cm².día respectivamente. Por su parte el bioplástico que se plastificó con glicerol, exhibió mejores propiedades mecánicas con relación al resto evaluado, con una tensión de 0,33 MPa, deformación del 25,40% y biodegradabilidad del 54,34% respecto al peso perdido.
