Csárdaszállás-Hanzély-tanya (MRT 10. 385. 4/21. lh.) embertani leleteinek vizsgálata
Authors: Bereczki Zsolt
Published: November 2022

A tanulmány egy 19 sírból álló temetkezési hely embertani leleteinek vizsgálatáról számol be. A leletek közül 17 egyén maradványain (13 avar kori, három 10–11. századi, valamint egy ismeretlen korú) volt lehetőség megfigyeléseket végezni. Az adatok összegyűjtéséhez és elemzéséhez a történeti embertanban szokásos makromorfológiai módszereket alkalmaztam. A 7–8. századi maradványok mind morfológiai, mind metrikus, mind patológiai jellegzetességeiket tekintve illeszkednek a korszakról eddig összegyűjtött ismereteink rendszerébe. A patológiai jellegek közül a 10. sír gyermekmaradványain láthatók fertőző vagy hiánybetegség nyomai, a 12. sír férfi maradványain megfigyelhető fertőzéses eredetű csigolya osteomyelitis és gerincsérv, a 14. sír női maradványainak feltehetően fertőzéses tünetei, illetve a 15. sír női koponyáján található jelképes trepanáció és a fertőzéses tünetek együttes előfordulása érdemel említést.
A korai magyar történelem régészeti kutatásainak aktuális eredményei és azok lehetséges nyelvészeti vonatkozásai
Authors: Türk Attila
Published: November 2022

A korai magyar történelem igencsak forrásszegény kutatási terület. Így a régészet, mint rohamosan gyarapodó forrásanyagú tudományág, kiemelkedő jelentőséggel bír. Fontos hangsúlyozni, hogy a régészet esetében a kutatási módszerek terén is jelentős bővüléssel számolhatunk, elsősorban a nagy lendülettel megindult bioarcheológiai vizsgálatoknak köszönhetően. Az utóbbi évek legjelentősebb magyar őstörténeti régészeti eredménye az etelközi szállásokkal azonosított Szubbotci-típusú lelőhelyek számának robbanásszerű növekedése volt a Dnyeszter középső és alsó folyásvidékén. A Dnyeper folyó középső és alsó folyása mentén jelenleg 10–12 lelőhely köthető az etelközi szállásokhoz. Itt jól tükröződnek a szomszédos, elsősorban az északi, szláv területekkel, valamint a Krím térségében a bizánci kultúrkörrel létrejött kapcsolatok. A leletanyag időrendje mellett annak jellege is kifejezetten összhangot mutat a muszlim források által a magyarok 9. századi elődeiről rajzolt képpel. Keletebbre a szamarai Volga-könyök és a Dél-Urál tágabb térsége továbbra is az, amely a magyar etnogenezis tekintetében a legtöbb kapcsolatot mutatja. Munkahipotézisként elmondhatjuk, hogy a magyarság elődeinek régészetileg legkorábban megfogható nyomát az Urál hegységtől keletre, a cseljabinszki Urálontúl régió keleti szomszédságában feltételezhetjük. Az itt élők egy csoportja feltehetően a 9. század elején indult el nyugati irányba. Ez a közösség rövid időn belül megjelent a Volga bal partján, és szállásterülete kiterjedt Volgai Bolgária határáig. Ezt követően egyik része a Káma mentén maradt. A másik csoport pedig még a 830-as évek előtt nyugat felé vándorolt, majd a Fekete-tenger északi előterében telepedett meg. A 890-es évek és a 10. század eleje között a Szubbotci-horizont jellemző tárgytípusai eltűntek a Fekete-tenger északi előteréből, ugyan-akkor felbukkantak a Kárpát-medencében, ahol megfigyelhető a továbbfejlődésük.
A 9/10‒11. század régészeti kutatásának helyzete a romániai Moldvában : Néhány gondolat a temetkezésekről és a szórványleletekről a balták kapcsán
Authors: Gáll Erwin
Published: November 2022

Moldvában a 10–11. század régészeti kutatásának jelenlegi elmaradott helyzete számos okra vezethető vissza. Emiatt jelen dolgozatunkban csak a leletanyag időrendi rendszerezését tűzhetjük ki célul. A Kárpát-medence és Bulgária területén, illetve egyes aspektusaiban egész Közép-Európában használt relatív kronológiai rendszert alkalmazhatónak találtuk Moldva esetében is, ennek azonban megvannak a maga korlátai, és a félreinterpretálás veszélyével is számolhatunk, de ebben a pillanatban jobb kiindulási pontot nem látunk. A más kelet-európai régiókban használt relatív kronológiai rendszer alapján 3 kronológiai csoportba sorolhatjuk a temetkezési helyeket, sírokat és szórványleleteket. Ugyanakkor szükséges hangsúlyoznunk, hogy a temetkezési helyeket és sírokat Kelet-Moldvában regisztrálták, míg a balták – szórvány- és depóleletként – a legnagyobb mennyiségben Nyugat-Moldvában kerültek elő. Hogyan értelmezhető ez a jelenség? Vajon életmódbeli különbségre utal, vagy egy adott kulturális különbség régészeti lecsapódására? Minderre a jövő kutatásai adhatnak választ.

Hyperthyroid patients may have increased or decreased radioiodine uptake on I-123 uptake and scan, which helps to differentiate the etiology of the hyperthyroid state. Thyroiditis is an uncommon complication of cancer immunotherapy and, in this situation, is likely secondary to an autoimmune response. The typical presentation of thyroiditis, regardless of the etiology, is elevated T4 and/or T3, low TSH and low radioactive iodine uptake. Herein we report a case of cancer immunotherapy-induced thyroiditis in a 34-year-old female diagnosed with right breast grade 2 invasive ductal carcinoma with ER and PR positive, Her2neu negative tumor markers. Due to her ER-positive tumor, 8-cycles of chemo-immunotherapy with Paclitaxel + Pembrolizumab were prescribed. The patient began to complain of intermittent palpitations halfway through her treatment, and her TSH after 6 cycles of treatment was <0.01 U/ml. She had negative TSI or anti-TPO (Pre-treatment TSH- 1.54 U/ml) antibodies. I-123 thyroid uptake and scan demonstrated faint thyroid activity with very low I-123 uptake, consistent with thyroiditis. Her treatment was ultimately continued and continued close monitoring of thyroid function tests was recommended.

Metastasis is the most commonly reported cause of cancer-related mortality. Therefore, elucidating the mechanisms that regulate cancer metastasis is essential. Tumor cells are known to preferentially grow in organs that promote and provide an adequate niche. Tumor metastasis is a selective process rather than a random process, which means that it has an organ specificity. It has been proposed that different organs produce distinct chemotactic factors that can attract specific types of tumor cells to home to and arrest in a particular organ. Chemokines and chemokine receptors have garnered much attention due to their roles in tumor invasion and metastasis. The chemokine receptor that we focus on is CCR7, the receptor for both chemokines CCL19 and CCL21. CCR7 has been implicated in the migration and trafficking of malignant cells in numerous types of tumors, but the mechanisms underlying these functions of CCR7 remain unclear. This review summarizes relevant perspectives on the functional mechanisms and prognostic significance of CCR7 in cancer.

Dirofilariasis is a cosmopolitan zoonosis of dogs and cats, accidentally affecting humans. Human dirofilariosis is a clinical entity caused by infection with nematode species of the genus Dirofilaria D. Repens is the most implicated species. It is responsible for benign skin manifestations but often poses problems of differential diagnosis. Although Dirofilaria infections are rare, we should be aware of their possibility. We reported a new Tunisian case of dirofilariasis presenting as a subcutaneous periorbital and frontal nodule caused by D repens in an old Tunisian man.
The influence of the gravitational effect on the spatial differentiation of economic development of poviats
Authors: Filipowicz Katarzyna , Tokarski Tomasz
Published: November 2022

The aim of the study is a statistical analysis of the impact of the so-called gravitational effect on the level of economic development of Polish poviats (districts) in the years 2002–2012. The gravitational effect of macroeconomic analysis is based on the assumption that the level of economic development of the poviat depends, i.a. of medium gravity. This factor connecting two regions is directly proportional to the product of the economic potential of these regions (measured by gross value of fixed assets per capita) and inversely proportional to the square of the geographical distance between these regions. The article describes the spatial variation of taxonomic indicators of economic development and the effects of gravity in the poviats. The paper presents the results of a statistical analysis of the impact of the gravitational effect of the diversity on economic development of the districts. The study takes into account both the effects of national (mutual poviats) and external (foreign neighbors on Polish counties economic development) gravitational interaction.

Published: November 2022

Weaning is one of the important management practices, which is mostly followed at organized dairy farms in India and abroad. Generally breeding programme at buffalo farms focusses on milk production, however weaning can additionally boost the total milk production of the dairy farm, apart from increasing the reproductive potential of adults and promoting scientific rearing of young calves. There is little information on early weaning of buffalo calves and its effect on production and reproduction performances of dams during post-partum in Indian buffaloes. However, early weaning may be associated with the restriction of colostrum feeding and essential nutrients for dairy buffalo calves. Breaking the maternal bond is stressful to the calf and lactating buffaloes, which can be evaluated by biochemical indicators of stress in bovine models. Although, weaning at birth is well established in dairy cattle, in case of buffaloes, it may yield significant outcomes in terms of estimating actual milk production and increasing precious buffalo milk in the market for human consumption. On the other hand, weaning practice in dairy buffaloes has been limitedly investigated and not reviewed properly under variable conditions. Keeping in view the impact of weaning, the present paper has been aimed to review the effect of weaning on performance of dairy buffaloes under tropical conditions. The weaning practices in dairy buffaloes can reduce the feeding cost of calves and increase the reproductive potential of the dairy animals through early resumption of post-partum ovarian cyclicity. However, more trials need to be conducted in dairy buffaloes for understanding the relationship between the behaviour of weaned animals and age of weaning towards better adaptability and optimum production at dairy farms.

The trial was undertaken in a completely randomized design to to evaluate the synergistic effect of probiotic (Pro), chicory root powder (CRP) and coriander seed powder (CSP) on the performance of broiler chicken. A total of 240 day-old broiler chicks were randomly allotted to six dietary treatments with 8 replicates of 5 birds in each. Treatment groups included T1 as control, i.e. basal diet (BD) without any growth promoter and T2 - BD + antibiotic (BMD @ 500 gm/ton). In the remaining experimental diets, T3 - pro (@ 10 gm/100 kg) + CRP (@ 1.0%), T4 - pro (@ 10 gm/100 kg) + CSP (@ 1.5%), T5 - CRP (@ 1.0%) + CSP (@ 1.5%) and T6 - pro (@ 10 gm/100 kg) + CRP (@ 1.0%) + CSP (@ 1.5%). The results revealed that supplementation of pro + CRP significantly increased the body weight gain during prestarter, starter and finisher phase and improved the feed conversion ratio during finisher phase compared to other treatment groups. Supplementation of different dietary groups did not show any significant effect on feed intake and various slaughter parameters of broilers. Whereas, the humoral immune response to ND vaccine and immune organ weights were significantly higher in all the test diets (T3 to T6) compared to control and antibiotic groups. Supplementation of probiotic with chicory combination group significantly reduced the serum total cholesterol and recorded higher returns over feed cost compared to other treatment groups. It can be concluded that combination of probiotic (10 g) with chicory root powder (1.0%) proved more effective than combinations of other additives.
Use of ketamine and xylazine anesthesia in dogs: A retrospective cohort study of 3,413 cases
Authors: LUTVIKADIC ISMAR , MAKSIMOVIC ALAN
Published: November 2022

The information regarding the risk of anesthesia-related death in veterinary medicine is scarce, and little is known about the mortality risk of specific anesthetics. The study conducted during 2019 at University of Sarajevo, Veterinary faculty, aimed to estimate the mortality risk of intermittent injectable ketamine-xylazine anesthesia in dogs and to investigate the potential relationship between mortality rate and anesthesiologists’ experience. Anesthetic records, where ketamine and xylazine combination was used for anesthesia induction and maintenance, were reviewed and divided into two groups: inexperienced (AN1) and experienced anesthesiologists (AN2). Inexperienced anesthesiologists were constantly supervised by experienced ones, whose corrective interventions were recorded. Overall detected mortality rate was 0.15%, with 0.18% and 0.11% in the AN1 and AN2 groups, respectively. A statistically significant difference was not found. Records of the AN1 group revealed interventions of experienced anesthesiologist in 92% of cases. Detected mortality rate was within the values previously established for inhalant anesthesia indicating high safety in usage of investigated protocol, if performed by experienced anesthesiologists. The high percentage of interventions of a senior anesthesiologist suggests that supervised upskilling of inexperienced anesthesiologists before their independent work could result in a better outcome.

Published: November 2022

Mrigal or Cirrhinus mrigala (Hamilton 1822) is one of the important aquaculture species in India. During 2017, mrigal contributed 5.7% to the aquaculture production of India. The present study was undertaken to describe the hatchery-level pre- and post-spawning condition, i.e. weight changes in the length-weight relationships (LWRs) and the weight-weight relationships (WWRs) associated with the two phases for the mrigal males and females used as broodstock from a commercial IMC hatchery. For the 18 pairs of individuals sampled, the TL (total length) ranged from 42–55 cm and 39–54 cm, and the BW (body weight) from 0.83–1.46 kg and 0.52–1.35 kg respectively for males and females. The GSI was recorded at 10.5% for males and 20.4% for females. The pre- and post-pawning weights differed significantly in both sexes based on paired t-test. Trends in the LWR and weight-weight slopes have been discussed in the article.

A set of 31 barley genotypes was evaluated at four locations, viz. Kanpur, Pantnagar, Varanasi and Faizabad for two years (2016 and 2017) against spot blotch [Biploris sorokiniana (Sacc.) Shoem.] resistance. The combined analysis of variance revealed significant influence of year (5.64%) and location (18.08%) effects with significant genotypic effects (29.05%). Location-wise, the highest susceptibility was observed at Varanasi (51.61%) followed by Kanpur (19.35%) whereas, the moderately susceptible reactions were obtained at Faizabad (67.74 %) and Kanpur (61.29%) locations. In heritability adjusted GGE biplot analysis, the ratio of (G+G × E)/(E+G+G × E) was estimated as 71.77 % and substantiated usefulness of generated biplots to elucidate resistant and stable genotypes with location discrimination. In AMMI analysis, the initial two principal components (PCs) cumulatively explained 90.7 % of total variation with individual scores of 51.8 % and 38.9 %, respectively. The triangular image of the initial three PCs depicted scattered pattern for disease reaction and varied response for the locations. The weather parameters, viz. maximum temperature, minimum temperature and sunshine hr/day showed strong correlations 0.87**, 0.83** and 0.64* with spot blotch severity. The genotypes, DWRB 180, PL 891 and DWRB 190 were found promising and suggested to be used in future resistance breeding and spot blotch genetic studies. The locations Varanasi and Faizabad were found type 2 discriminative and representative environments for spot blotch.

Published: November 2022

An experiment was conducted to identify bacterial wilt disease-causing isolates of Ralstonia solanacearum (Smith) in Tanzania. The pathological and biochemical descriptors were used to determine the virulence and biovars of 40 bacterial isolates originating from 200 wilted tomato (Solanum lycopersicum L.) stems collected from the main agro ecological zones of Tanzania. Results revealed that 53% of the investigated isolates were pathogenic, whereas 90% of isolates belonged to biovar 3 and the rest (10%) were biovar 2. Biovar 3 was present in all of the surveyed agroecological zones, whereas biovar2 prevailed in Southern zone only and is reported for the first time in Tanzania. This is an alert for plant health officers to implement standard phytosanitary measures in preventing new introduction and spread of Ralstonia to uninfected locations. Descriptors adopted successfully identified biovars of Ralstonia, thus can be integrated with other diagnosis tools to manage bacterial wilt disease.

A field experiment was conducted during kharif 2016-17 at ICAR-Indian Agricultural Research Institute, New Delhi to assess the long term impact of conservation agriculture (CA) on productivity, profitability and input-use efficiency of rice (Oryza sativa L.) under a rice-wheat cropping system (RWCS). Pooled results revealed that rice grain yield under the CA-based zero till direct seeded rice (ZTDSR) + mungbean residue (MR) – zero till wheat (ZTW) + rice residue (RR) – zero tilled summer mungbean (ZTM) + wheat residue (WR) both with 100% N (4.9 t/ha) and 75% N (4.8 t/ha) was statistically comparable to the conventional practice, i.e. transplanted puddled rice (TPR) – conventional till wheat (CTW) (5.2 t/ha) and TPR – ZTW (5.4 t/ha). Although rice grain yield under ZTDSR+MR–ZTW+RR– ZTM+WR [100% N] was ~5.7% lower compared to farmers’ practice TPR–CTW, net returns of rice (₹ 41.1×103 / ha) was 119.5% higher compared to TPR-CTW, chiefly due to the lower cost of cultivation of ZT-DSR (₹ 47.5×103 / ha) as compared to CT-TPR (₹ 74.8×103 /ha). Partial factor productivity of NPK was highest under the CA treatment ZTDSR+MR–ZTW+RR–ZTM+WR [75% N] (32 kg grain/kg NPK) while ZTDSR+MR–ZTW+RR–ZTM+WR [75% N] [100% N] observed the highest irrigation water use efficiency (0.57 kg/m3). Thus, the novel CA practice ZTDSR+MR–ZTW+RR–ZTM+WR can provide comparable rice yields with higher net returns and nutrient (75% N) and irrigation use efficiencies compared to conventional farmers practice TPR–CTW and hence its adoption may be recommended.

Authors: Japhet Paul , Maluka Stephen
Published: November 2022

Maternal and neonatal mortality are largely caused by delays in attending to obstetric complications and this is attributed to limited women’s power in making decisions regarding household resources and utilisation of health care services. This requires effective implementation of male engagement interventions to improve women’s autonomy in making decisions and hence reduce delays in attending to obstetric complications. This study examines the contribution of male engagement interventions in promoting women’s autonomy in decision making within households and society. A structured questionnaire was used to collect data on socio-demographic and household characteristics, women’s practices concerning prenatal care, childbirth, postnatal care, and related decision-making power. Descriptive statistics and inferential analysis were used to analyse the data. The findings show a significant difference in decision making autonomy regarding family planning methods among respondents who had received male engagement education versus those who had not received such education (p-0.001<1%). Again, there was significant participation of women in household purchases for daily needs (p-0.057<10%) and in decisions to work out of homes (p-0.015<5%). This trend was noted among respondents who had received male engagement education as compared to those who had not received such education. There was also greater engagement of women in decision making concerning major household purchases and their health care, although their engagement was not statistically significant (p-0.397>10% and p-0.293>10% respectively). Effective implementation of male engagement interventions may leverage men’s power within households and promote women’s autonomy in decision making, thereby improving healthcare-seeking behaviour.

Sinonasal Glomangiopericytoma: A Case Report
Authors: Raji T Naidu  , Susan Cherian  , Vaishnavi Kumba  , Uma Chaturvedi
Published: November 2022

Sinonasal glomangiopericytoma is defined as a low-grade malignant tumor demonstrating a perivascular myoid phenotype. We report a case of sinonasal glomangiopericytoma having a diffuse architecture with bland spindle cells arranged in short fascicles, storiform, whorled, reticular pattern, separated by a vascular plexus ranging from capillaries to large patulous spaces. Immunohistochemistry is required to differentiate it from other perivascular tumours and solitary fibrous tumour. However, differentiating glomangiopericytomas and solitary fibrous tumours based on immunohistochemistry is a challenge. The tumour expressed vimentin, focal smooth muscle actin and CD34, diffuse, strong Bcl2 and Beta catenin and negative STAT6. Immunohistochemical expression of STAT6 is useful as a negative marker in the diagnosis and separation of glomangiopericytoma from solitary fibrous tumour.
Key Messages: Sinonasal glomangiopericytoma (SNGP), a rare tumour with low malignant potential as per WHO classification is frequently confused with sinonasal solitary fibrous tumour (SFT). This article emphasizes the importance of using a broader immunohistochemical panel of positive and negative markers for differentiating SNGP from SFT. The most useful among them being CD34, SMA, BCL2, Beta Catenin and STAT6.
Electricity Production Sources and CO2 Emission in OECD countries: Static and Dynamic Panel Analysis
Authors: Voumik Liton Chandra , Islam Md. Jamsedul , Raihan Asif
Published: November 2022

Industrialization, urbanization, population growth, and changes in lifestyle have all contributed to a rise in the OECD countries' risk of global warming. The amount of carbon dioxide (CO2) generated from heat and power sources put out is directly related to how much electricity they make. Finding out which sources are bad for the environment, and which are not is the primary motivation behind this study. The impact of different approaches to energy production on carbon dioxide emissions is analyzed using OECD data. The data is analyzed using Quantile Regression (QR), Generalized Method of Moments (GMM), and Pooled Ordinary Least Squares (OLS). The study found that CO2 emissions were significantly impacted in a positive direction when electricity was generated using coal, oil, or gas. The emissions from coal-fired power plants are the most detrimental. The generation of hydroelectricity and other forms of renewable energy can reduce CO2 emissions in all regression models. The most compelling evidence of a correlation between CO2 emissions and energy sources was uncovered in this study. In order to produce credible findings, the paper used both QR and GMM methods. Important implications for environmental policy are drawn from this article's findings. Both are required to lessen our reliance on fossil fuels and promote the development of renewable energy sources like solar, wind, and hydroelectricity.

La educación para la paz responde a la necesidad de los educadores de asumir un rol activo en la transformación de las culturas en donde se ha asimilado la violencia, para poner en práctica los valores, principios y prácticas que propicien la armonía social. La libre expresión de opiniones en el aula de clases es un pilar fundamental para lograr minimizar los conflictos, aprovechando la divergencia de pensamientos para forjar la concordia a través del diálogo en que se puedan respetar los diferentes puntos de vista sin necesidad de imponer ideas, más bien favoreciendo la reflexión y crítica constructiva. La libertad de expresión de opiniones de los estudiantes universitarios en el aula como parte fundamental de la educación para la paz, contribuye a dejar atrás las actitudes de violencia que han imperado, mejorando las condiciones de vida de la sociedad en general.

El conflicto cognitivo, es un término que pertenece a la teoría constructivista del aprendizaje, busca generar conocimientos y es pieza clave si se quiere lograr aprendizajes significativos, así mismo, es una herramienta que favorece el desarrollo de funciones ejecutivas, por lo que su uso es fundamental si se quiere aplicar principios de neuroeducación. A continuación, un pequeño espacio para reflexionar en tan interesante tema.
La discriminación racial étnica en Guatemala
Authors: Reyna Gómez Luis Edgardo
Published: November 2022

Al momento de escribir sobre este tema llama la atención lo poco que durante algunos años a través de lecturas y discusiones sobre el mismo se ha venido abordando en algunos sectores académicos de la sociedad guatemalteca, toda vez que como se sabe se ha tratado de invisibilizar al indígena como que se quisiera negar su existencia, es decir que desde la percepción de quien escribe, no se encuentra hasta la fecha una solución al mismo. De tal manera que se ha pensado en una serie de ideas que van desde la integración, la ladinización y hasta más extremas la exterminación, para dar soluciones a lo que las elites conciben como problema, un problema que gracias a sus existencia les ha permitido concentrar grandes riquezas y mantener en estado de pobreza al sector indígena que tanto desprecian pero que inevitablemente se convierte en la base de esa acumulación desmedida, bajo la misma protección del Estado. Sin siquiera considerar al indígena como un sujeto pensante capaz de ser impulsor de su propio cambio. De hecho, como una manera de prevenir la discriminación se ha llegado a considerar este fenómeno como algo legal desde el momento que se ha tipificado como delito en el artículo 202 bis, que configura el delito de Discriminación, mediante la reforma al Decreto 57-2002 del organismo legislativo. Como queriendo dar respuesta a la contradicción entre la sociedad legal y la sociedad real, producto de la constitución de los estados modernos.
Germinación de especies forestales nativas del bosque nuboso en sustratos organominerales
Authors: Pérez Vásquez Cupertino Ovidio
Published: November 2022

Objetivo: establecer el comportamiento de germinaci´ón de cuatro especies forestales nativas del bosque nuboso utilizando sustratos órganominerales. Método: Se valuaron tres sustratos y cuatro especies forestales nativas, siendo las variables evaluadas: porcentaje de germinación de cada especie y la interacción con el sustrato. Se utilizó el diseño de bloques completamente al azar -DBCA- con dos repeticiones lo que permitió conocer las variables porcentaje de germinación, mejor sustrato e interacción sustrato-especie. Para analizar los resultados se les aplicó el análisis de varianza con un 95% de confiabilidad utilizando el software de acceso libre INFOSTAT. Resultado: se puede indicar que el sustrato 50% de suelo con alto contenido de limo + 50% de humus de bosque latifoliado presentó mejores resultados en la especie Quercus acatenanguensis con un 93% de germinación, con ello se evidencia que se puede generar sustratos de fácil adquisición para los pequeños productores de germoplasma.
Primeros billetes de banco en Guatemala: Banco Nacional de Guatemala (1874-1876)
Authors: Quisquinay Rojas Edgar Daniel
Published: November 2022

El uso de papel moneda en Guatemala no es tan antiguo como el de moneda metálica. Aunque se dieron varios intentos para su instauración y circulación, sobre todo durante la fase de independencia temprana, no es sino hasta 1874, durante el gobierno de Justo Rufino Barrios, que se logra, no solo poner en circulación billetes, sino fundar el Banco Nacional, institución que los respaldaba. La crisis de circulante, la caída de los precios de los productos de exportación y el inicio del cultivo del café dan pie a este fenómeno que, a su vez, iniciará la apertura de bancos privados.
El telégrafo, fuente para la historia local. Colección itinerante de telegramas del Archivo Histórico Municipal “Hugo Armando del Valle Rodríguez” –AHMSM- San Marcos
Authors: Tánchez Iscayá Ruth Adriana
Published: November 2022

De relevancia para la historia local, es el acervo documental que resguarda el Archivo Histórico Municipal de San Marcos AHMSM y para este caso nos referimos de manera específica a la Colección Itinerante de Telegramas que datan de 1876, sólo tres años después de la inauguración del Telégrafo en Guatemala. La importancia de este medio de comunicación, por su rapidez, brevedad de texto y privacidad se convirtió de uso primordial para las autoridades y personas privadas. Recorriendo la colección se va dando forma a cómo, en la cotidianidad se vivieron los cambios que generaron la Reforma Liberal en sus primeros años y cómo se caracterizó por la presencia de gobiernos dictatoriales para imponer el modelo económico agroexportador primario periférico. El cual favoreció a familias que forjaron su capital durante el periodo colonial y otras que emergen conforme avanza el siglo XIX y confluyen para el impulso de la producción del café en el país. Son 73 años marcados por cuatro dictaduras y la imposición de leyes de trabajo forzado y despojo de tierras a pueblos originarios, mayas mames. El artículo hace uso del telegrama como una fuente que va recreando el contexto económico, político y social de la denominada Reforma Liberal en sus inicios y que se extendió como Período Liberal.
Desarrollo del comercio electrónico y marketing digital en las micro y pequeñas empresas. El caso de San Pedro Sacatepéquez, San Marcos
Authors: Fuentes Fuentes Marcia Etelvina
Published: November 2022

El objetivo de esta investigación es demostrar el impacto que ha tenido el comercio electrónico y el marketing digital en las micro y pequeñas empresas que funcionan en el municipio de San Pedro Sacatepéquez, departamento de San Marcos. Para el efecto se toman como escalas de análisis zona 1 y 2. La metodología utilizada de esta investigación es cuantitativa. Se empleó un muestreo simple por conveniencia, tomando en cuenta que el municipio a la fecha se encontraba en semáforo rojo. Se seleccionó 50 micro y pequeñas empresas para que respondieran una boleta de opinión, depurando y validando 47 de ellas. Los resultados de la investigación muestran que la mayoría de los negocios aplican el comercio electrónico y no el marketing digital, porque carecen de los conocimientos y de las estrategias idóneas para emplearlo adecuadamente, la mayoría de ellos operan en las redes sociales de manera empírica lo cual se convierte en una debilidad, sin embargo, se vieron beneficiados en sus negocios al aplicar esta modalidad de comercio.
Apuntes en torno al pensamiento sociológico de Peter Berger y Thomas Luckmann
Authors: López Mazariegos Hugo Rafael
Published: November 2022

Tras haber analizado el libro la construcción social de la realidad de Peter Berger y Thomas Luckman, en este análisis esbozaremos algunas cuestiones que nos permiten ubicar el pensamiento sociológico y rescatar las ideas más relevantes de la obra de   Berger y Luckman dos escritores norteamericanos emblemáticos del siglo XX. En este trayecto hemos elegido ir de principio a fin siguiendo la estructura misma del ensayo, pero sin pretensión de exhaustividad. Berger y Luckman presentan algunos aspectos de su pensamiento en un conjunto sistemático de reflexiones que tienen por objetivo señalar claves de lectura y comprensión de su itinerario teórico alrededor de temas como el lenguaje, identidad, religión, y también el objeto más conocido de los autores, la sociología del conocimiento. Finalmente, hacemos algunas observaciones y comentarios de la obra, la forma en que Berger y Luckmann fundamenta dicho proyecto desde el positivismo, así como su ubicación y su aporte específico dentro del conjunto de las principales corrientes de la sociología contemporánea.
Procesos cognitivos y resiliencia en el maltrato infantil
Authors: Sojuel Icaj Daniel Eduardo , Véliz Escobar Carmen María
Published: November 2022

El maltrato infantil es un fenómeno que desemboca en diferentes consecuencias que se pueden presentar durante la historia personal, por ello se exploran en el artículo los resultados de estudios que indagan sobre la relación existente entre el maltrato infantil y los procesos cognitivos. Se ha evidenciado que las experiencias de vida estresantes tienen efectos a nivel cerebral, lo que conlleva a alteraciones cognitivas, así mismo, se ha encontrado que el factor de la resiliencia es determinante en este punto, pues la investigación al respecto ha demostrado que tiene una base neurocientífica. La vinculación entre ambos temas ha contribuido a la ampliación de conocimiento en el contexto del maltrato infantil, dando pautas que podrían explicar la variedad de respuestas encontradas de parte de las víctimas. Resultados relevantes han demostrado que el maltrato infantil tiene efectos a nivel neurológico que pueden afectar los procesos cognitivos, y que la resiliencia representa un verdadero factor de protección ante los efectos adversos del maltrato infantil, explicando la adaptación y mejor desarrollo en algunas áreas cognitivas que presentan las víctimas.

Staff members use tried-and-true procedures when completing workplace visits, delivering services, and completing tasks for clients. However, the COVID-19 pandemic compelled employers to change the work styles of individual employees to ensure good communication, work-life balance, and flexibility for employees while maintaining optimal work productivity levels. In addition, the World Health Organization established social separation guidelines to combat COVID-19. The pandemic thus, challenged the work culture and also resulted in employees being quarantined in their homes. As a result of this transformation, employees were being encouraged to use digital tools to facilitate work-from-home opportunities. The current study aims to analyze employees' psychological and productive effects of work-from-home culture. It also looks for coworker bonding that is threatened by this transformation and suggests a way to keep it intact. Through a thorough review of the literature, the authors developed a comprehensive model to assess the pandemic's impact on employees' lifestyles. The conceptual model was empirically tested by applying the model to data collected from 233 employees from various backgrounds. The model result was validated using Partial Least Squares Methods- Structural Equation Modeling. The inferences highlight the factors influencing employee morale and work culture, as well as the parameters closely related to employee functioning in the organization that should not be affected.

Taller integrado: gemelos digitales y fabricación a escala natural
Authors: Estepa Rubio Antonio , Elía García Santiago
Published: November 2022

In this paper we present a pedagogical practice carried out, transversally, between several subjects of the first year of the Degrees in Architecture and Digital Design and Creative Technologies throughout the second semester. This work has been repeated two years in a row to draw accurate conclusions. There are two global objectives sought. First; use digital tools to determine the conditions linked to the design, learning along the way the specific peculiarities of the computer programs with which it has been operated. The second; overcome the barrier of graphical planning through the construction of an original full-scale prototype, with which students understand the situations derived from the design at the time of manufacture, for this example, according to the restrictions of use of cardboard.

En este artículo presentamos una práctica pedagógica llevada a cabo, de forma transversal, entre varias materias del primer curso de los Grados en Arquitectura y Diseño Digital y Tecnologías Creativas a lo largo del segundo semestre. Este trabajo se ha repedido dos años seguidos para, de forma más certera, extraer conclusiones verosímiles. Son dos los objetivos globales pretendidos. El primero; utilizar herramientas digitales para determinar las condiciones vinculadas al diseño, aprendiendo a lo largo del camino las sigularidades específicas de los programas informáticos con los que se ha operado. El segundo; superar la barrera de la planificación gráfica a través de la construcción de un prototipo original a escala natural, con lo que se consigue que los estudiantes comprendan las situaciones derivadas del diseño en el momento de la fabricación, para el caso que nos ocupa, ciñiéndose a las restricciones que implica el uso de cartón.
