Validating a portable device for groundwater iron measurement in Bangladesh
Authors: Sarwar Sneha , Rahman Sabuktagin , Saha Nobonita , Ahmed Shamim Abu , Hasan M. Aziz , Shaheen Nazma
Published: September 2024

The mineral iron is essential for health at an optimum level. In Bangladesh iron is obtained from the drinking source groundwater, attributing largely to the good iron status in population. This groundwater iron poses two scenarios—predominantly high in many areas and predominantly low in other areas. Despite good iron status, burden of anemia in population is high. To control anemia, iron supplementation programs are operational against the backdrop of high iron status. This often leads to iron-associated side effects, plausibly due to excess iron, especially among the individuals exposed to high amount of iron from the drinking water. This geological phenomenon warrants the supplementation program to deliver different doses depending on the groundwater iron level. To enable that, the country needs an area-representative “mapping” of groundwater iron. However, such a mapping using the gold standard laboratory methods is expensive and logistically intensive. The aim of the study is to validate Handheld Colorimeter (HI721 Checker® HC), a portable device (“spot kit” device) to measure iron concentration in the drinking groundwater. The study was carried out in the rural Belkuchi upazila of the Sirajganj district in the Rajshahi division. In the study 25 tubewells were selected and categorized into five groups. Among them, four were categorized based on their iron concentration, low iron conc. (0-<1 mg/L), medium iron conc. (1-2 mg/L), high iron conc. (2-10 mg/L), very high iron conc. (>10 mg/L). One additional group was included for tubewell water that was used after filtering. The study compared the iron estimates measured in groundwater samples of the selected tube wells by the spot kit device and the same samples measured by atomic absorption spectrophotometry (AAS). There was a high agreement between the estimates by the spot kit and AAS (Kappa coefficient= 0.72, p <0.001; Lin’s concordance = 0.829, p < 0.001). Pitman's test of difference in variance exhibited that the two methods produced equally precise results (r=0.227, p=0.275). The study concluded that the Handheld Colorimeter (HI721 Checker® HC) was valid to measure the iron concentration of groundwater under field conditions. This device can facilitate testing processes, particularly in remote or resource-constrained areas where sophisticated testing methods (i.e: AAS) are unavailable and thus may help the re-design of the anemia control program in settings like Bangladesh with high and variable level of iron in the drinking groundwater.
Food culture, lifestyle & traditional food festivals: a narrative on the public health relevance of the traditional yam recipes in the Afikpo New Yam Festival
Authors: Uro-Chukwu Henry Chukwuemeka
Published: September 2024

Food culture has over the years remained the centre for socio-cultural linkages among people in a community, with generational transmission giving birth to cultural affinity and cultural heritage. Besides its primary aim of nourishment, enhancement of growth and body functions, it also defines religious and traditional belief systems. Several communities, tribes and nation states such as China, Italy, Japan, India, Europe and Americas, have been associated with unique food cultures. In North and West African countries like Tunisia and Nigeria respectively, food cultures abound. In South-East Nigeria, the Igbo tribe conduct yam rituals as food cultural festivals. Afikpo, a community in the Igbo-speaking part of Nigeria, celebrates an annual yam ritual called Ikeji Festival, part of which, as the new yam is harvested, is preparation of traditional yam recipes. This article reviews the nutritional content of the various traditional yam recipes consumed in such ceremonies and the associated drinks. A literature search revealed that yam, an energy-giving food with a carbohydrate content of 15 – 40.6%, could be prepared with vegetables, legumes, fish, meat, melon seeds, red palm oil, African black beans, pumpkin fruit pulp, eggplants, African oil bean, piper guineese, plantain, solanum americanum, vitex donians, pterocarpus santalinoids, which are sources of minerals, vitamins, antioxidants, dietary fibres and polyunsaturated fatty acids, all of which have been documented as beneficial in the management of chronic diseases. Alcoholic and various soft drinks are consumed with the yam recipes during the ceremony and there are possibilities that if awareness is not created, overindulgence could constitute to abuse.

Skilled women migrants in the 21st century: Pasifika English Language Teachers' journeys to South Korea
Authors:   , Yates Rachel
Published: September 2024

This ethnographic research follows the migration journeys of 15 Pasifika women teaching English in South Korea. Guided by the metaphor of a gogo’s life cycle, this dissertation explores various stages of Pasifika women’s migration to Korea in the 21st century. The research examines the contextual factors that facilitate migration, Pasifika women’s motivations for migration, their in-person and digital experiences of integration and transnationalism, and highlights the transcultural capital and skills they utilise while abroad.

A qualitative Pacific Studies and mana tama‘ita‘i approach to research (Marsh, 1999, Teaiwa, 2000; 2017) was used to reveal the experiences of Pasifika women and their gendered migration journeys as English Language Teachers (ELTs) to Korea. Data was collected from talanoa, field notes, storying work, and auto-ephemera—a method that combines autoethnography and ephemera to incorporate my own experiences as a former English Language Teacher (ELT) in Korea. These narratives reveal how gendered Pasifika cultural norms shape the migration experience; Pasifika Indigenous ways of knowing related to family, respect, service and relationship maintenance manifest in Korea, helping Pasifika women cope and thrive in their new environments. Drawing on the concept of transcultural capital (Triandafyllidou, 2009), I highlight how Pasifika women ELTs intentionally transfer and utilise these ‘skills’ to their advantage as migrants in Korea.

In the uplifting spirit of a fāgogo (Kolone-Collins, 2010; Ta‘isi Efi, 2011), these stories offer insights into the experiences of Pasifika women ELTs, challenging the stereotypes and cultural expectations they face. This ethnography uncovers a previously unexamined migration pathway within Pacific migration literature.
Breaking the Stigma: Housing for the Homeless
Authors:   , Alipuria Smita
Published: September 2024

Homelessness is a complex issue affecting countries worldwide, Including New Zealand. Homelessness is a growing problem throughout New Zealand, with StatsNZ data from 2020 indicating 41,644 people experiencing housing deprivation (Sta, 2020), particularly impacting young individuals, Māori, and Pacific Islanders. Wellington alone had an estimated homeless population of 1254 individuals in 2018 (Amore et al., 2021). Growing up in Wellington, I have seen first-hand, the increasing population of homelessness. Streets are being filled everyday by people without homes. Factors contributing to homelessness include the lack of affordable housing, unemployment, mental health issues, substance abuse, trauma, and criminal convictions (Sta, 2020). Temporary solutions like, placing individuals in motels often lack safety and support services, exacerbating the problem. Loafers Lodge in Wellington exemplifies inadequate housing conditions for the homeless, with a recent fire, raising concerns about safety standards. This research investigates a community-oriented design approach to permanent housing in Wellington, prioritising community integration, well-being, and adaptability.

The research methodology involves a literature review, analysis of case studies, site selection, and engagement with housing providers and homeless individuals.

Analysing precedent studies offered insights to inform future architectural interventions for homelessness. Key findings highlighted the importance of flexible and adaptable design, community integration, thoughtful planning, environmental considerations, and access to nature. Case studies such as De Eendracht and the Schröder House illustrate innovative solutions for adaptable living, while examples like Wij_Land Housing demonstrate the socio-petal design's effectiveness in fostering community connections. Trauma-informed design principles emphasize creating spaces that alleviate anxiety and stress, promoting emotional well-being.

Parking spaces are unused and under-utilised spaces that could potentially be repurposed as homes, while revitalising life back into an empty, unused parking lot. Homelessness requires a shift in mindset towards prioritising human dignity, connection, and belonging. In cooperating innovative design strategies, communities can work together and create inclusive environments where everyone has a place to call home. This thesis proposes a community-orientated design aimed at creating a housing concept for homeless individuals in Wellington.

Evidencia arqueológica recuperada hace más de un siglo y los resultados de investigaciones másrecientes sugieren que la isla de la Plata y cerro Jaboncillo, preeminentes lugares sagrados de lacosta central del Ecuador, fueron seleccionados por los incas como sitios claves para establecersu presencia en la región y definir sus relaciones con el pueblo nativo manteño. En la isla de laPlata, se han registrado entierros sacrificiales inca del tipo capac hucha y una ofrenda masiva deSpondylus acompañada de un urpu inca; y en el cerro Jaboncillo, dos grupos de estructuras depiedra, identificables como observatorios dedicados al monitoreo de los solsticios, se componende formas arquitectónicas claramente incas. Estas evidencias en conjunto con otras, examinadasen el contexto tanto de una presencia inca más amplia en la región como de intervenciones enotras provincias del imperio, conducen a una reevaluación de la estrategia inca con respecto a lacosta ecuatoriana. Conducen, además, a una consideración de cómo, en práctica, los incas y losmanteños hubieran interactuado, y, de ahí, cómo la presencia inca podría haber impactado a lasociedad manteña.

El artículo presenta información sobre un conjunto de datos arqueobotánicos obtenidos en lasexcavaciones arqueológicas de las terrazas de Joyagzhí. Estos proveen la primera evidencia enlas estribaciones occidentales de los Andes del Ecuador, sobre como las sociedades prehispánicasKañaris gestionaron sus sistemas de cultivos agroecológicos para la producción intensiva delmaíz (Zea mays), durante una prolongada trayectoria histórica de 1200 años (240 DC-1438 DC).La metodología incluyó además de los análisis arqueobotánicos (recuperación, identificacióntaxonómica, cuantificación e interpretación), un estudio etnoarqueológico inferido desde elcontexto sistémico de la diversidad agrícola de la comunidad Kichwa de Nizag. En el caso de lamaterialidad generada por los sistemas de cultivos, cada operación agrícola da lugar a un tipode muestra con una composición botánica única y específica. Se demuestra que la estabilidad yelasticidad de la agricultura pudo ser sostenida bajo modelos de intensificación progresiva, sinque esto represente un retroceso natural irreversible de los procesos ecosistémicos. Siemprey cuando, se incluyan prácticas agroecológicas en beneficio del cuidado de las especies deimportancia económica a través del control cultural de una agrobiodiversidad conscientementeseleccionada. Finalmente, se corrobora que estas ingenierías agrícolas monumentales fueronconstruidas por sociedades cacicales Kañaris y más no por el imperialismo ecológico Inca.

Published: September 2024

Autism spectrum disorder (ASD) is significantly known as social interaction impairment that can be reduced through early school-age intervention. The quasi-experimental research design was used to examine the effect of applied behavior analysis treatment on ASD children's interpersonal skills. The researchers used a purposive sampling technique to select 30 participants who have symptoms of ASD, which were divided into two groups (control and experimental) without gender discrimination. The assessment of basic language and learning skills (ABLLS-R) protocol and portage guide of early education was used to develop a questionnaire comprising four factors. The results indicate a statistically significant difference between the experimental and control groups in terms of students' interpersonal skills and the pretest and post-test scores of the experimental group. It is suggested that parents and therapists should develop a sharing ability among children with autism symptoms so they can understand social reinforcement.

La escasez de agua en la región manzanera más importante de México; Cuauhtémoc, Chihuahua, se ha incrementado considerablemente en las últimas décadas. El objetivo de esta investigación se concentró en evaluar la respuesta en crecimiento y desarrollo de portainjertos de manzano injertados con ’Golden Delicious ‘, sometidos a cuatro ciclos de sequía, comparándolos con el tratamiento de riego continuo. Se evaluaron 10 portainjertos (B.9, M.9Nic29, G.41, G.202, G.890, G.210, G.30, M.7, MM.111 y MM.109), los cuales son utilizados en las huertas comerciales de manzano de la zona de Cuauhtémoc. Todos los portainjertos se obtuvieron de viveros comerciales durante la estación de crecimiento 2019. La plantación se realizó en macetas de 20 L en el mes de marzo de 2020 y se utilizó un sustrato compuesto por composta, suelo y arena en proporción 1:1:1. Las variables registradas fueron; porcentaje de humedad en el suelo, crecimiento de la rama líder, potencial hídrico de la hoja, biomasa total, y uso eficiente del agua. Los portainjertos B.9 y M.9Nic29 mostraron buenos resultados en la mayoría de las variables estudiadas. Los portainjertos B.9, M.9Nic29, MM.111 y G.210 mostraron buena recuperación del potencial hídrico de la hoja después del riego de recuperación. La biomasa total fue estadísticamente igual en G.30, G.41, MM.111, MM.109, G.202 y B.9. Se concluye que existen portainjertos que toleran cierto grado de sequía y que pueden contribuir a mejorar el uso del agua, destacando B.9.

Published: September 2024

Al utilizar cromatografía de gases acoplada a espectrometría de masas se determinaron las concentraciones de microcontaminantes orgánicos (MCO) en agua de riego en 15 parcelas localizadas en el valle de Atlixco-Izúcar en Puebla. De manera similar, se determinaron las concentraciones de tales contaminantes en suelos regados con agua del río Sinú en la cuenca del río del mismo nombre en el departamento de Córdoba en Colombia. Tanto en las aguas de riego de México, como en los suelos de Colombia, las concentraciones de los MCO analizados superan por mucho los valores encontrados en matrices similares en entornos agrícolas de España, lo que indica la necesidad de atender el monitoreo y tratamiento adecuado de las aguas con las que se va a regar.

El quitosano es un bioestimulante de origen natural que estimula el crecimiento y desarrollo de los cultivos, mejorando el rendimiento de los mismos. Diversos estudios han probado la eficacia del quitosano para mejorar la producción de pepino, sin embargo, la dosis óptima del quitosano aún no se ha determinado, por ello el objetivo del presente estudio fue| determinar el efecto de seis concentraciones de quitosano sobre el crecimiento y producción del cultivo de pepino. Seis tratamientos: T1 = Testigo ; T2 = Quitomax 100mg.L-1 ;  T3 = Quitomax 200 mg.L-1  ; T4 = Quitomax 300 mg.L-1 ;  T5 = Quitomax 400 mg.L-1    y T6 = Quitomax 500 mg L-1, fueron aplicados mediante aspersión manual a los 15, 30 y 45 d después del trasplante del hibrido de pepino Diamante F1, utilizando un diseño experimental de bloques al azar. Se registraron las variables longitud de la guía, número de frutos por planta, longitud, diámetro y peso del fruto, y el rendimiento en kg ha-1. La longitud de la guía se midió a los 15, 30 y 45 d, por lo que para esta variable se utilizó un modelo de mediciones repetidas en el tiempo y medias de mínimos cuadrados para comparar las concentraciones de quitosano, para el resto de las variables se utilizó un análisis de polinomios ortogonales para determinar la respuesta de las variables a las diferentes concentraciones de quitosano. Todas las variables se vieron incrementadas en respuesta a la aplicación de quitosano, presentándose una respuesta lineal positiva. Se concluye que el quitosano influye en el crecimiento y desarrollo de la planta del pepino, incrementando su rendimiento a medida que se incrementa la dosis de quitosano. La dosis de 500 mg L-1 en este estudio fue la que tuvo los mejores resultados. Se sugiere la necesidad de estudiar dosis más altas de quitosano

Los hongos micorrícicos arbusculares, un método prometedor para incrementar la calidad de cosecha agrícolas, pueden hacer frente a la creciente demanda de alimentos con altos aportes nutrimentales. El objetivo fue evaluar el efecto de la inoculación micorrícica nativa y comercial en Cucurbita moschata y Cucurbita pepo, var. “Grey Zucchini”, sobre variables de crecimiento morfológico, calidad de cosecha y postcosecha del fruto. La inoculación micorrícica inició en etapa de semillero con 60 esporas por tratamiento. En campo, se estableció un diseño de parcelas divididas (seis tratamientos-14 repeticiones). T1: Cepa nativa 1 (sistema agrícola) + 50% de fertilización química; T2: Cepa nativa 2 (sistema multipropósito) + 50% de fertilización química; T3: Cepa nativa 3 (vegetación secundaria) + 50% de fertilización química; T4: Cepa comercial + 50% de fertilización química; T5: Sin inoculación por 100% de fertilización química; Testigo: Sin inoculación por fertilización. Las variables evaluadas fueron: altura, grosor, brotes/flores; número de frutos, peso y diámetro; para calidad postcosecha: color, grosor de cáscara, textura, humedad, pH, cenizas, acidez titulable y sólidos solubles. C. pepo, representó la especie con mayor afinidad micorrícica. Asimismo, los resultados determinaron que las variables de crecimiento de los cultivos no presentaron diferencias estadísticas. Asimismo, en peso y tamaño del fruto se observó un efecto significativo entre la inoculación micorrícica nativa/comercial y el tratamiento con el 100% de fertilización. En calidad postcosecha, C. pepo, registró diferencias en textura, acidez titulable, colorimetría y grosor del fruto. C. moschata, en solidos solubles, textura y colorimetría. En conclusión, la inoculación micorrícica arbuscular en ambas especies, reduce el uso de fertilizantes químicos durante su cultivo, influyendo positivamente en la calidad de cosecha (peso y diámetro) y en atributos poscosecha (propiedades físicas y químicas) del fruto, relevantes para el consumo humano.

El laboreo intensivo de suelos y el desarrollo de cultivos con uso excesivo de agroquímicos podrían producir un aumento de los contenidos de algunos metales pesados como cromo, níquel, cadmio y plomo. La determinación de estos elementos en condiciones de invernadero no ha sido debidamente evaluada en República Dominicana. Por lo que el objetivo de este estudio fue determinar las concentraciones de estos metales en suelos dedicados a la producción hortícola en condiciones controladas. Se evaluaron 40 suelos provenientes de invernaderos en cinco localidades: Jarabacoa, Constanza, Moca, Villa Trina y San José de Ocoa. Los datos se analizaron mediante estadísticas descriptivas, análisis de correlación de Pearson, análisis de varianza no paramétrico y prueba de Kruskal Wallis. Los valores promedios de Cr, Ni, Cd y Pb oscilaron entre 27.0 y 63.7, 30.0 y 77.8, < 0.002 y 1.8 y < 0.002 y 29.4 mg kg-1, respectivamente. Los mayores contenidos promedios de Cr, Ni, Cd y Pb se encontraron en invernaderos de San José de Ocoa con 63.7, 77.8, 1.8 y 29.4 mg kg-1, respectivamente. Los contenidos de Cd en las localidades restantes fueron < 0.002. El Mn y el Zn no presentan diferencias estadísticas significativas entre localidades (P ≤ 0.05); sin embargo, el Zn se encuentra dentro de los niveles deseables (3-15 mg kg-1). La variación de estas concentraciones podrían ser atribuidas al tipo de suelo y material de origen, aunque estos factores no fueron estudiados. Se concluye que los contenidos promedios de los metales pesados evaluados no excedieron los límites ambientales; siendo altas las concentraciones en algunos invernaderos, lo que debería llamar la atención por la posible acumulación de éstos en el suelo y consecuentemente en los cultivos.

The aim was to evaluate the ef fect of maximum temperature on yield and water use ef ficiency in forage corn with subsurface drip irrigation and surface irrigation in five consecutive growing seasons (spring and summer) in the comarca Lagunera. The study was carried out at the La Laguna Experimental Field, of the National Institute of Forestry, Agricultural and Livestock Research (INIFAP) in Matamoros, Coahuila. The research was carried out during summer 2019, spring 2020, summer 2020, spring 2022, and summer 2022 growing seasons. The variables were: maximum temperature, plant height, dry forage, water depth, and water use ef ficiency. The highest temperatures were recorded in spring 2022 and the lowest in the summer growing season of the same year. Overall, the highest plant heights occurred in the coolest growing season (summer 2022). A higher yield of dry forage (19 Mg ha-1) was in the 2022 summer growing season. The highest water depth was applied in the spring 2022 growing season (71 cm) and the lowest in summer 2020 (55 cm). This resulted in higher water use ef ficiency in summer. The variation in water use ef ficiency between growing seasons was due to higher temperatures in spring. Finally, water use ef ficiency tended to decrease by 19% as temperature increased from 30 to 38 degrees Celsius.

La mayoría de los productores de pepino en invernaderos de baja tecnología no presta atención al efecto de la humedad del aire sobre sus cultivos. La humedad relativa (HR) afecta la transpiración de las plantas y la traslocación de nutrimentos hacia la parte aérea, teniendo como resultado un efecto en el estado nutrimental. En este estudio se planteó determinar si la concentración de la solución nutritiva, en términos de conductividad eléctrica (CE) (1.7, 2.2 y 2.7 dS m-1), afecta el crecimiento, rendimiento y calidad de frutos en pepino creciendo bajo diferente HR (35%, 50%, 65%). Comparado con las plantas de HR a 35%, el rendimiento aumentó en 14 y 17% cuando la humedad fue de 50 y 65%, respectivamente. Sin embargo, este aumento fue más marcado al suministrar soluciones nutritivas de baja concentración (1.7 dS m-1). En condiciones de alta HR (65%), disminuyó la concentración de NO3– (-21%), K+ (-16%), y Ca++ (-14%) en el extracto de la savia del peciolo, mientras que en los frutos ocurrieron tendencias similares con el NO3– (-26%) y el K+ (-13%). En contraste, el Ca++ aumentó hasta 24%. La HR modificó el balance entre el NO3–, K+ y Ca++, siendo el óptimo de 19.3 para el K+/Ca++ en frutos y de 8.7 para el NO3–/Ca++ en el peciolo. Se concluye que el pepino produce mayor rendimiento y calidad de fruto cuando la HR del invernadero se mantiene en 65% en combinación con una baja concentración de la solución nutritiva (1.7 dS m-1).

Introducción. La esclerosis múltiple es una enfermedad crónica progresiva y neurodegenerativa cuyas tasas de incidencia y prevalencia vienen aumentando a nivel mundial. Uno de los problemas que presentan los pacientes con este trastorno es la falta de equilibrio debido a la degradación progresiva de la mielina, para lo cual recientemente se ha sugerido el pilates como método de intervención.
Objetivo. Realizar una revisión sistemática de la literatura sobre la eficacia de realizar ejercicios de pilates para mejorar el equilibrio en pacientes con esclerosis múltiple.
Métodos. Se realizó una revisión sistemáticas de la literatura siguiendo el protocolo de la declaración PRISMA. Se consultaron las bases de datos PubMed, CINAHL, PsycINFO, SPORTDiscus, Academic Search Complete, LILACS, IBECS, Cochrane Controlled Register of Trials (CENTRAL), SciELO y Web of Science (WOS).
Resultados. Se obtuvieron 72 estudios y tras la eliminación de los duplicados y la aplicación de los criterios de inclusión se seleccionaron 6 ensayos, con un total de 208 pacientes, para incluir en el análisis. La duración del programa de pilates osciló entre 6 y 12 semanas y todos los estudios demostraron seguridad con la implementación del método pilates y que no se produjeron efectos secundarios importantes con la implementación de este.
Conclusiones. Los ejercicios de pilates son eficaces para mejorar el equilibrio en pacientes con esclerosis múltiple y constituyen una alternativa de tratamiento superior a la atención estándar. Esta metodología también mejora la capacidad para caminar, la movilidad funcional, la estabilidad postural, la interacción sensorial, la calidad de vida, la fuerza, la resistencia, la velocidad al caminar, las funciones respiratorias y las funciones cognitivas, y además disminuye la fatiga y los factores de riesgo conocidos de caídas.
LUCHISM IN THE THEATER: CONCEPT OF STAGE LIGHT OF M. LARIONOV
Authors:   ITMO University, Spiridonova Anna M.
Published: September 2024

The subject of the research is the concept of stage light (“light space”) by M. Larionov, described in the text “On Luchism in the theater”. The goal of the research is revealing of the concept of stage light. The article represents M. Larionov's vision of the problem of stage light, insignificant for the history of the theater, but important for the history of fine arts, since the concept of “light space” traces the development of luchism outside of painting. The article analyses five elements of the theatrical light of luchism, reveals a complex light “score” in the projects of M. Larionov and N. Goncharova. The work determines the compliance of the provisions stated in the texts with the scenic practice of artists. Both realized and unrealized performances preserved in the form of documents are considered. The article compares the scenographic practices of Luchism and Constructivism. Scientific innovation of the research: the concept of “light space” is represented for the first time, the light scenography of M. Larionov's theatrical productions is proposed to be considered as one of the stages of luchism, namely plastic luchism.
THE INFLUENCE OF GEORG SIMMEL`S PHILOSOPHY ON WILHELM WORRINGER`S ART THEORY
Authors:   Lomonosow Moscow State University, Gumerova Roksana F.
Published: September 2024

This article critically analyses the main theses of Wilhelm Worringer's paper “Abstraction and Empathy” to show that they correspond to the neo-Kantian views of Georg Simmel and the philosophy of life presented in his later works. Simmel's texts do not provide detailed explanations of the transcendental method or categories. To ensure an accurate interpretation of Simmel's ideas, his works are examined in the context of the methodology of Hermann Cohen of the Marburg School of Neo-Kantianism, under whose direct influence he was. Only then are they compared with Worringer's text. To avoid any misunderstanding regarding Worringer's application of neo-Kantianism, the article clearly outlines Kant's original teachings, which the art historian used as a foundation for his own terminology.

Authors: Murat Dilek , Güzel Simla
Published: September 2024

Ülke ekonomilerinin gelişmesi açısından önemli bir yere sahip olan rekabetçilik ve inovasyon 1970’lerden itibaren üzerinde çok durulmaya başlanan konular haline gelmiştir. Ekonomik performansın iyileşmesi için rekabetçi bir ekonomiye sahip olmak gerekir. Rekabetçiliği de güçlendiren en önemli etkenlerden biri inovasyon olarak kabul edilmektedir. Bu çalışmada verilerine ulaşılabilen Ekonomik Kalkınma ve İş birliği Örgütü (OECD) ülkelerinin rekabet ve inovasyon alanındaki performanslarının analiz edilmesi amaçlanmaktadır. Söz konusu alanlardaki performansı etkilediği düşünülen kriterler; Küresel Rekabet Endeksi (Global Competitiveness Index-KRE), yenilik belirleyicileri olarak da Ar-Ge harcamaları, toplam patent sayısı, işgücü verimliği ve araştırmacı sayısı şeklinde belirlenmiştir. Çok Kriterli Karar Verme (ÇKKV) yöntemi olan EDAS (Evaluation based on Distance from Average Solution) metodunun kullanıldığı çalışmada en güncel verilere ulaşılabilen yıl olan 2022 yılı verileri kullanılmıştır. Elde edilen ampirik bulgulara göre en iyi performansa sahip ülkenin Japonya olduğu ve bunu Amerika Birleşik Devletleri (ABD) ve Kore’nin izlediği tespit edilmiştir. Rekabet ve inovasyon konularının bir arada incelenmesi ve OECD ülkeleri özelinde EDAS metodu performans analizi yapılması yönüyle çalışmanın literatürdeki boşluğu dolduracağı düşünülmektedir.

Aim: This study aimed to investigate the relationship between polycystic ovary syndrome in adolescents, a disease caused by inflammation and insulin resistance that is associated with metabolic disorders, and platelet indices, which provide information about platelet activity.
Materials and methods: Patients with oligoovulation, hyperandrogenemia, or clinical signs of hyperandrogenism (hirsutism, acne, etc.) and polycystic appearance with ≥ 20 small follicles ≥ 2∼ 9 mm in diameter in both ovaries on ultrasound according to the newly updated Rotterdam criteria were included in the study with a diagnosis of polycystic ovary syndrome and formed PCOS group. Patients with similar age groups and body mass index (BMI) values who presented to the clinic for non-PCOS symptoms (vaginitis, dysmenorrhea, cystitis), whose complete blood count was checked during hormone testing, and who did not meet the Rotterdam criteria were selected as the control group.
Platelet indices found in routine blood count parameters (platelet large cell ratio (P-LCR), platelet distribution width (PDW) and mean platelet volume (MPV)) were analyzed between the two groups. In addition, the relationship between these indices and hormone status and insulin resistance in PCOS patients was analyzed. Patients with diabetes mellitus, hypertension, malignant diseases, cardiovascular diseases, essential thrombocytopenia or other blood diseases and patients taking medication were excluded.
Results:
In the study of 123 patients, there was no statistically significant difference between the groups in terms of age and body mass index (p:>0.05). When hemogram parameters were compared between the groups, hemogram parameters such as P-LCR (p: 0.002), PDW (p: 0.011) and MPV (p: 0.007), which indicate platelet activity, were statistically significantly higher in the PCOS group. When the data of PCOS patients were analyzed, platelet indices were found to be higher in the group with high insulin resistance (p:
