Authors: Palomo-Avellaneda Leopold , Rosell Jan , Raúl Suárez , Zaplana Isiah
Published: October 2023

Una de las aplicaciones más conocidas del álgebra geométrica en la ingenierìa consiste en proporcionar una formulación compacta de la cinemática de los robots manipuladores serie. Sin embargo, el uso de álgebra geométrica en el campo de la robótica está aún en sus inicios, y todavía hay varios problemas abiertos que pueden ser tratados con esta elegante y compacta formulación. En esta línea, el presente artículo introduce una estrategia basada en el álgebra geométrica conforme para resolver el problema de la cinemática inversa para un robot manipulador de 6 grados de libertad (GdL) sin muñeca esférica, para el cual es conocido que el problema de la cinemática inversa no tiene, en general, solución analítica. Para ello, la estrategia propuesta en este artículo se basará en la explotación de las propiedades algebraicas y geométricas del álgebra geométrica conforme como, por ejemplo, que toda isometría se puede representar de manera compacta como un rotor, y que los objetos geométricos no son más que multivectores.
Evaluación experimental del sistema de teleoperación LiCAS para aplicaciones de robótica aérea y de servicio en base fija
Authors: Suárez Fernández-Miranda Alejandro , Ollero Baturone Aníbal
Published: October 2023

Este artículo presenta la evaluación experimental de un sistema de teleoperación cinestético desarrollado para la realización de tareas de manipulación diestra con dos brazos robóticos en aplicaciones aéreas o de base fija, tales como operaciones de mantenimiento en entornos industriales, o la recogida y entrega de paquetes en escenarios logísticos. El sistema consta de una pareja de brazos antropomórficos de muy bajo peso con capacidad de acomodación mecánica (LiCAS) en configuración maestro-esclavo, de tal forma que los movimiento aplicados por el usuario humano en el maestro se replican articulación por articulación al robot esclavo, resultando en una interfaz natural e intuitiva que facilita la transferencia de las habilidades de manipulación entre el humano y el robot. El muy bajo peso de los brazos robóticos (1 - 2.5 kg) hace posible su integración en plataformas multi-rotor de medio tamaño y su fácil despliegue en cualquier escenario de interiores o exteriores. Las capacidades del sistema de teloperación LiCAS han sido evaluadas con una placa de prubeas para manipuladores industriales, así como en una operación de manipulación aérea.

Authors: Martínez-Inchusta Alberto , Sierra García Jesús Enrique , Santos Matilde , Leija Lorenzo
Published: October 2023

Cada día los sistemas de control son más complejos; los controladores de turbinas eólicas son un claro ejemplo de ello. Esto conlleva una demanda creciente de nuevas técnicas de verificación y validación que minimicen los posibles riesgos durante la fase de implementación en el dispositivo final. Las pruebas MIL (Model In the Loop), SIL (Software In the Loop), PIL (Processor In the Loop) y HIL (Hardware In the Loop) se realizan en momentos específicos del desarrollo del producto con el objetivo de obtener un sistema de control robusto y confiable de cara a su integración en el mundo real. El método de validación PIL ejecuta el software de control en el hardware real y comunica éste con la planta virtual, todo ello en tiempo real y de forma determinística. Esta técnica de validación permite corroborar que el software de control se ejecuta dentro de los tiempos de procesado requeridos (valida el hardware) y que las salidas generadas son las correctas para llevar al sistema a su estado objetivo (valida el software de control). En este trabajo se ha demostrado la posibilidad de implementar un PIL mediante un controlador desarrollado en IEC- 61131 ejecutado en tiempo real basado en PC y una planta virtualizada bajo Simulink Desktop Real-Time®.

Detección de aeronaves en trayectoria de colisión de vuelo mediante optical flow
Authors: Cabrera Juan José , Gil Arturo , Luis Payá , Reinoso Oscar , Rodríguez David
Published: October 2023

En este artículo se presenta un método que permite detectar UAVs mediante una única cámara instalada en una aeronave y, además, es capaz de predecir si existe riesgo de colisión. Se emplea la información del flujo óptico disperso presente en la imagen para: (1) modelar mediante una matriz de homografía el movimiento en la imagen debido al propio movimiento de la cámara, (2) compensar el movimiento en la imagen y (3) segmentar todo aquel flujo óptico cuyo movimiento es diferente al provocado por la cámara con objeto de detectar el UAV presente en el espacio aéreo. Además, se predice una posible colisión analizando la colinealidad existente entre el vector posición del UAV con su vector velocidad (salvo un factor de escala). Los resultados experimentales muestran que el método propuesto es efectivo en la detección, seguimiento y predicción de la colisión entre UAVs con independencia de su apariencia, tamaño y movimiento, lo que puede ser útil para aumentar la seguridad del espacio aéreo.
Un método para la calibración de un sistema LiDAR y cámara fisheye
Authors: Martinez Ballester Alvaro , Flores Tenza María , Payá Luis , Gil Aparicio Arturo , Jimenez Garcia Luis Miguel
Published: October 2023

El uso de sistemas de percepción que combinan sensores LiDAR y cámaras se está haciendo cada vez más frecuente, pues la fusión de sus datos proporciona una ayuda para la percepción del entorno. Además, las tareas de detección de objetos o la segmentación semántica del entorno precisan, frecuentemente, la combinación de sensores de diferente naturaleza con el objetivo de mejorar sus resultados. La calibración de estos sistemas es un paso fundamental para la correcta fusión de los datos. En este artículo se propone un método de calibración basado en un patrón para este tipo de sistemas, formados por una cámara fisheye y un LiDAR. El método evita transformar las imágenes a un modelo pin-hole, realizando una calibración a partir de la proyección esférica de la imagen, obtenida mediante los parámetros de calibración y la nube de puntos correspondiente.
Exploring agriculture, climate change, and food planning nexus
Authors: Delgado Cecília
Published: October 2023

In Portugal, local answers to climate change and food are basically twofold: the approval of a Climate Adaptive Strategy or Plan, which are largely being formulated by Portuguese municipalities and the voluntary signature of the Glasgow Food and Climate Declaration. As both folds are not binding their impact is limited. However, a recent Portuguese framework Law on Climate [2021], aligned with the European Green Deal, imposes that all municipalities must approve a municipal climate action plan before summer 2024. Such a context opens up a window of opportunity to reflect on the lessons learned from the already approved Climate Adaptive Plans and Strategies.
Therefore, we explore in this paper the following inter - connected questions: (1) to what extent Climate Adaptive Plans and Strategies include the increase of local food production; (2) Do they consider each step of the food chain or solely food production? (3) To what extent are those measures transcribed into the planning rules and regulations.
In order to do so, we analysed 14 Climate Adaptive Strategies or Plans of a selected group of cities that entered the national competition ECO XXI, based on a sustainable framework of multiple dimensions. In 2021, as much as 57 out of the 308 Portuguese municipalities entered the competition.
Results suggest that adaptive measures relate to increasing local agriculture, mapping out land availability or highlighting the need for local agroecological practices. Moreover, Climate Adaptive Strategies or Plans, measures and actions are predominantly related to agriculture production, leaving behind subsequent food chain activities. This is probably happening due to a narrow and sectorial vision of agriculture that do not consider each one of the stages of the food chain. Lastly, the inclusion of several measures and actions into planning instruments is quite promising, even if still fragile to transform existing reality.
In conclusion, there is an urgent need to expand among food stakeholders the understanding of food and agriculture as part of the food system. In addition, there is a need to increase planner’s awareness to these topics as in practice the link between food, climate and planning is still missing. Findings highlight that the potential role of planning is not being fully unleashed. Such a consideration is in line with other international studies confirming that Portugal is not an exception. Therefore, lessons we learned might turn useful for other countries.

Authors: Jaiswal Kavita M. , A. Austina , Abraham Jijo Philip , Thomas Augustine V.
Published: October 2023

Background: Promotion of drugs by pharmaceutical industries is fully regulated by drug regulators. Doctors are focus of intense marketing by representatives of pharmaceutical companies (MR). It is reported that very few physicians are equipped with the necessary skills and knowledge to critically assess the information delivered in drug promotional literature (DPL). Hence this study was carried out with the objective to determine knowledge, attitude and practices of doctors about the DPL
Methods: This was a questionnaire-based study population included clinicians working in a government set up and others doing private practice. Questionnaire was circulated online on social media platforms via Google forms.
Results: The 32.11% participants were aware of regulations and guidelines of DPL in India  80.7% participants searched  for cost of medicine on DPL, 54.12% respondents perceive that the product claims made on DPL are balanced and supported by good evidence, 56.88% participants opined that their integrity is compromised by accepting gift  from MR, 43.1% participants are exposed to drug advertisement through social media and 51.06% of them opined that their prescribing habits are influenced through this. Writing brand names while prescribing is significantly more in private practitioners   as compared to doctors employed in government set up.
Conclusions: DPL serves to update the knowledge of the busy clinicians of the latest developments in the medical field. Quality check of drug promotion on social media is the need of the hour as this is influential. Private practitioners need to be addressed regarding enforced laws for rational prescribing.

Published: October 2023

Background: β-Blockers are often associated with further cardiac function deterioration, ledding to them being often underused/underdosed by certain physicians in heart failure treatment, although they were seen to be beneficial in decreasing the rates of mortality and morbidity, duration of hospitalization in HFrEF patients, but data on their benefits in HFmEF and HFpEF patients is limited. Objective was to evaluate rationality of β-blockers’ dosage regimen and its effectiveness in HF patients.
Methods: 43 HF patients have been enrolled. Data were collected from the medication chart (dose, route, frequency); dosage regimen was evaluated and compared to that of ESC guidelines for HF treatment. Heart rates pre/post drug treatments, ejection fraction (at admission & post-discharge) were recorded; effectiveness was evaluated through heart rate control, reduction in: duration of hospitalization, rehospitalization and mortality rate. Post-discharge updates of the patients were obtained through out-patient consultation reports.
Results: In All 43 patients dosage regimen of selected β-Blockers was found to be rational and following the ESC guideline for HF treatment. 65% of patients spent not more than 5 days in the hospital, 16% Re-hospitalized for cardiovascular diseases, and death rate was 4%.
Conclusions: The dosage regimen of selected β-Blockers was found to be as per that of ESC-guidelines HF treatment. β-Blockers have also been found to have reduced: hospitalization stay, frequency of rehospitalization, and death rate among patients under study.

Published: October 2023

Diabetes mellitus is a growing health problem with a significant global disease burden. The complications and mortality rate associated with diabetes are increasing. Albuminuria is one of its complications and evidence of established nephropathy. Low toe–brachial index (TBI) is more strongly associated with albuminuria and may be a suitable tool for evaluating peripheral arterial disease in patients with type 2 diabetes mellitus. Our study evaluated the association between macro albuminuria and low toe brachial index in type 2 diabetic patients to identify those who need specialized foot care and adequate renal protection.

Published: October 2023

Background: Ovarian carcinoma is the seventh most common cancer among women worldwide and the eighth leading cause of death. Ovarian cancer develops in the ovary's tissues.
Methods: This cross-sectional descriptive study was carried out at the Department of Pathology, RMC and Department of Pathology, BSMMU, Dhaka, Bangladesh from July 2019 to June 2021 carried out with 31 histopathologically confirmed ovarian carcinomas. All cases were subjected to WT1 immunostaining followed by histopathological examination. The collected data were analyzed using Statistical Package for Social Sciences (SPSS) software, version-23.0. The ethical clearance of this study was obtained from the Institutional Review Board (IRB) of Rajshahi, Medical College, Rajshahi, Bangladesh.
Results: A total of 31 histopathologically confirmed ovarian carcinoma patients were included in this cross-sectional descriptive study. All cases were subjected to WT1 immunostaining followed by histopathological examination. The age of the study sample ranged from 20 to 75 years. The mean age of the respondent was 45.10±13.78 years. According to the histologic subtypes, WT1 was mainly expressed in serous carcinoma. All the serous carcinoma (16/16) showed a positive reaction for WT1. Among them, 14 cases (87.5%) showed >50% (3+) WT1 score and two (2) cases (12.5%) showed 11% to 50 % (2+) scores. Regarding endometrioid carcinoma four (4) (66.6%) of six (6) were negative whereas one (1) (16.6%) showed 1%-10% (1+) and one (1) (16.6%) showed 11%-50% (2+) WT1 scores. All the mucinous (4/4) and all the clear cell carcinoma (3/3) were negative with less than 1 % of the tumor cells stained two (2) cases of undifferentiated carcinoma were also negative. There was a significant relation between WT1 expression and different histologic subtypes of epithelial ovarian carcinoma with a p value of 0.001 (p<0.05).
Conclusions: WT1 can be applied by both the histopathologist and clinician as an effective marker regarding diagnosis and patient management.
Rifampicin induced acute thrombocytopenia with skin rashes: a case report
Authors: B. Loknath , Babu Venkateswara
Published: October 2023

Rifampicin is an essential component of the treatment regimen for tuberculosis. Extensive clinical experience has shown that the drug has mild adverse effect, but on rare occasions, it can cause life threatening adverse reactions like thrombocytopenia. Blajchman et al first described rifampicin-induced thrombocytopenia in 1970. Since then, almost 40 cases have been documented in the literature and a recent review by Cooper and Ghanima included rifampicin in the group of not uncommon drugs that cause immune-mediated thrombocytopenia. Diagnosis of drug-induced immune thrombocytopenia is by identifying clinical symptoms and a careful evaluation of the suspected causative drug. The physician treating tuberculosis patients must be aware of this rare life-threatening complication, when we detected early, is completely reversible.

Authors: Naseema Shaik , Supriya Yannamani , Kotha Alekhya , Vidyasagar P. , Rao Bikkasani P. Lakshmi Kishan
Published: October 2023

Background: Dermatophytosis has acquired an epidemic-like magnitude at the present times. The prevalence of the dermatophytosis is reported to be as high as 61.5% in some parts of the country. Hence, to address the management of the situation, we therefore studied 30% salicylic acid as a peeling agent for the treatment of dermatophytosis.
Methods: 40 patients (25 males & 15 females) having dermatophytosis with positive potassium hydroxide (KOH) mounts were enrolled and Salicylic acid 30% application was done over the lesions weekly upto 4 weeks, and then followed up weekly upto 4 weeks.
Results: 5 patients were treatment-naive, and 30 was receiving antifungal treatment in the past 6 months. A total of 30(85%) patients had achieved clinical and microbiological cure 1 week after the last salicylic acid application. Clinically, the lesions appeared to have significantly resolved with reduction in hyperpigmentation and size of the lesions. 5 patients (15%) were still KOH-positive at the end of the study period and showed clinical activity; but these patients reported symptomatic improvement.
Conclusions: 30% Salicylic acid both keratolytic and anti-inflammatory effects shows it’s effect on tinea, which prevent drug resistance and facilitating fast cure of superficial dermatophytoses. Salicylic acid peels can be used successfully as an adjuvant in the treatment of tinea infections and to enhance the activity of antimycotic drugs.

Published: October 2023

O principal foco desse artigo é dialogar com o matriarcado enquanto conceito filosófico vivenciado pelos grupos falantes do iorubá, trazido ao Brasil pela diáspora oriunda do tráfico, que se iniciou no século XVI, apresento-lhes conceitos e reflexões buscando analisar possibilidades de como se processou a estruturação ordenadora das casas de culto de tradição iorubá, que, oficialmente, são identificadas a partir do século XIX, bem como a constituição do poder na hierarquização da religião afro-brasileira, que passa pelo modelo matriarcal, que tem seu foco no papel da mulher iorubá; como catalisadora primordial dos cultos afro-brasileiros em uma (re)conquista do ‘poder’ ancestral das Ìyámís, vivenciado no território africano iorubá. Esta compreensão é ampliada pela perspectiva de que as mulheres iorubás, ao conjugarem a nova ordem religiosa, configurada como afro-brasileira, abrangeram a complexa estrutura organizacional dos palácios dos obás/reis iorubás (LIMA,2010).Para tanto essa análise reflexiva baseia-se em pesquisadores africanos e afro diaspóricos que se ocupam em compreender o matriarcado como princípio filosófico ancestral assim como afirma Adiop ( 1986 ). Assim em diáspora o artigo reverencia o legado de uma das Iyalorixás mais conhecidas da Bahia da década de 30. A Iyálorixá Eugênia Ana dos Santos, Obá Biyí,

Published: October 2023

Reunimos estudos que visam, a partir do conceito de ‘colonialidade do poder e de gênero’, refletir sobre a herança de matriz africana, implicita na religiosidade aqui exercida, e como esta, está diretamente relacionada às raízes da população negra e as fronteiras impostas a partir desse lugar. A trajetória das mulheres negras aqui narradas refletem a presença e o papel do matriarcado nesse contexto, e, sobretudo, o papel da religião para essas mulheres. Os textos retomam fragmentos da história do Brasil, que possibilitam repensar o ‘patriarcado’ brasileiro, a partir do Candomblé, das irmandades católicas, dos movimentos políticos e culturais em busca de justiça germinando o feminismo negro.
CATOLICISMO E REVOLUÇÃO CUBANA (1959 – 1960)
Authors: Zaldivar René Villaboy , Silva Wellington Teodoro
Published: October 2023

O tema desse artigo está situado no momento auge da Guerra Fria. Ele apresenta resultado de pesquisa sobre a revolução cubana e a Igreja Católica nos dois anos iniciais do governo revolucionário (1959 – 1960). A instituição religiosa competiu com outros setores políticos pela influência no novo regime instalado. Antes de entrar nesse tema central, o texto apresenta um breve recuo histórico para o período colonial e republicano. Isso é necessário devido a singularidade da Igreja Católica na ilha caribenha. As dificuldades que a hierarquia religiosa encontrou em ser admitida como interlocutora relevante no momento posterior à vitória não se deveu ao novo momento político nesses dois anos analisados, mas ao fato de ter sido feita uma instituição estrangeira ainda no período colonial.
HISTÓRIA E CINEMA

Published: October 2023

No artigo tivemos o objetivo central de evidenciar uma narrativa histórica sobre a Conquista de México-Tenochtitlan no filme Eternos. Analisamos diálogos e imagens de cenas. Concluímos que aquela narrativa se dá, majoritariamente, a partir da superioridade bélica espanhola, dando pouco espaço aos aliados dos espanhóis, os indígenas. Colocamos esse resultado em discussão e percebemos que o filme está mais alinhado com uma interpretação oitocentista, que eleva os feitos dos espanhóis na Conquista.

Role of early clinical exposure for clinical training among medical undergraduate students
Authors: Maheshwari K Uma
Published: October 2023

Early clinical exposure (ECE) is a teaching-learning method which leads to the clinical exposure of first year medical students and also aids them to interact with patients as early as the first year of medical curriculum. ECE sessions help the students to improve their academic strength, clinical, and communication skills thus making them more confident. ECE makes an overall impact on student's performance and enhances their confidence in the first phase of medical curriculum. Planning of ECE can be done in different settings with the use of resource materials such as logbook, textbooks, instruments, case sheets, and computers. The Medical Council of India in new educational reforms made ECE sessions compulsory from 2019 in undergraduate medical curriculum. This review highlights the different roles of student in ECE sessions, different ECE settings during its implementation in regular teaching.

Authors: Singh O Gambhir , Shandil Anil , Kumar Sanjeev , Kumar Shiv Ranjan , Abhay Abhinav
Published: October 2023

Homicide by blunt head injury is relatively common as the most frequently involved organ when a blunt weapon is used to be the head. Head is one of the most vital parts in our body. Sometimes, such a case may be subjected to burns to hide the actual cause of death or to destroy the identity of the victim. Identification may be very difficult when there is involvement of head and face and this may be even more difficult when there is absence of body belongings and ornaments. Involvement of hands may destroy finger ridges too making it unsuitable for preservation of fingerprints. In this case report we examined a case of homicide by blunt head injury which was later on burned to destroy identity of the individual and to mislead the investigating officers in the determination of the cause of death.

AIM: To evaluate the therapeutic effect of folic acid combined with decitabine on diabetic mice.
METHODS: The diabetic model of db/db mice were randomly divided into model group, folic acid group, decitabine group, folic acid combined with decitabine group, and C57 mice as normal control group. The density of retinal blood vessels and retinal thickness were detected by fundus photography and optical coherence tomography, respectively. Pathological changes of retina were observed by hematoxylin-eosin (HE) staining. The homocysteine (Hcy) in serum was detected by enzyme linked immunosorbent assay (ELISA). TdT-mediated dUTP nick-end labeling (TUNEL) was used to detect apoptosis in retinal tissue. Evans blue dye was used to detect the permeability of retinal blood vessels. The platelet endothelial cell adhesion molecule-1 (CD31) and vascular endothelial growth factor receptor (VEGFR) protein were detected by Western blot. The 3-nitrotyrosine (3-NT) and 4-hydroxynonanine (4-HNE) were detected by immunohistochemistry.
RESULTS: The density of retinal blood vessels, retinal thickness, retinal vascular permeability and the proportion of apoptotic cells of retinal tissue in the model group increased significantly than control group (P<0.05). The Hcy in serum and the levels of CD31, VEGFR, 3-NT, and 4-HNE in retinal tissue increased significantly in the model group (P<0.01). Folic acid and decitabine both reversed these changes significantly, and the combination of the folic acid and decitabine worked best.
CONCLUSION: The combination of folic acid and decitabine has a more significant protective effect on the retina in diabetic mice.

AIM: To compare the postoperative binocular visual performance with an iTrace analyzer following femtosecond laser-assisted cataract surgery (FLACS) combined with bilateral implantation of two different types of diffractive trifocal intraocular lenses (IOL).
METHODS: During this retrospective observational study, patients who received bilateral FLACS combined with implantation of two different types of diffractive trifocal IOLs were evaluated. According to the IOLs’ different types and design, the patients were divided into AT LISA tri839MP group (tri839 group) and AcrySof PanOptix TFNT00 group (TFNT group). Study parameters included preoperative and postoperative uncorrected distance visual acuity (UDVA) at 5 m, uncorrected near visual acuity (UNVA) at 30 cm and 40 cm, uncorrected intermediate visual acuity (UIVA) at 60 cm and 80 cm, postoperative refractive status, objective visual qualities and total high order aberrations (HOAs) postoperatively. The postoperative complications were also recorded.
RESULTS: Totally 56 eyes of 28 patients (tri839 group, n=26; TFNT group, n=30) were included. Preoperative baseline characteristics between groups were not statistically significantly different. UDVA was not significantly different between groups except for 1wk follow-up due to the postoperative corneal edema. TFNT group showed statistically significant better UNIA at 60 cm than tri839 group at the 1wk (0.05±0.19 vs 0.15±0.10 logMAR, P=0.013), 1mo (0.05±0.12 vs 0.15±0.09 logMAR, P=0.001) and 3mo (0.04±0.12 vs 0.15±0.11 logMAR, P=0.001) follow-up, while tri839 group showed statistically significant better UNIA at 80 cm than TFNT group at the 1d (0.14±0.15 vs 0.20±0.14 logMAR, P=0.041) and 1mo (0.09±0.07 vs 0.14±0.10 logMAR, P=0.042) follow-up. Postoperative refractive status showed stable at every visit. Modulated transfer function (MTF) values and strehl ratio (SR) values were improved and HOAs were lower significantly after surgery.
CONCLUSION: FLACS with bilateral implantations of both tri839 and TFNT00 can achieve satisfactory natural whole-course vision, high postoperative refractive stability and good visual quality but without significantly difference. iTrace aberration instrument can accurately evaluate the visual quality under different status.

AIM: To compare the clinical outcomes between two approaches for sutureless scleral-fixated intraocular lens (SFIOL) in children with Marfan syndrome (MFS).
METHODS: The study included 15 children (26 eyes) with lens subluxation due to MFS. These children underwent lensectomy, anterior vitrectomy, and sutureless SFIOL. According to the position of placement of intraocular lens (IOL) haptics, two study groups were reviewed for best corrected visual acuity (BCVA) and postoperative complications: group A, 14 eyes with haptics fixated at 2.0 mm from the limbus; group B, 12 eyes with the haptics fixated at 2.5 mm from the limbus.
RESULTS: The mean axial length for all patients was 25.66±2.35 mm. Postoperative BCVA in logMAR were significant improved in both groups (0.77±0.32 to 0.17±0.12 in group A, 0.66±0.25 to 0.24±0.12 in group B, both P<0.001) while no significant difference between two groups (P>0.05). Pupillary capture was main postoperative complication, occurring between 3d and 18mo. It occurred in 7 eyes in group A and one eye in group B (P=0.02).
CONCLUSION: Sutureless SFIOL is an effective treatment approach for lens subluxation in children with MFS. Pupillary capture is the main postoperative complication. Fixated IOL haptics at 2.5 mm from the limbus can reduce the occurrence of pupillary capture.

AIM: To investigate the changes in corneal biomechanics and posterior corneal surface elevation after femtosecond laser-assisted in situ keratomileusis (FS-LASIK).
METHODS: Totally 197 eyes of 100 patients who underwent the FS-LASIK from April 2022 to November 2022 were included. They were divided into three groups according to the ratio of residual corneal stroma thickness/corneal thickness (RCST/CT): Group I (50%≤RCST/CT<55%, 63 eyes of 32 patients), Group II (55%≤RCST/CT<60%, 67 eyes of 34 patients), and Group III (RCST/CT≥60%, 67 eyes of 34 patients). The intraocular pressure (IOP), corneal compensated IOP (IOPcc), corneal hysteresis (CH) and corneal resistance factor (CRF) were measured immediately, 1, and 3mo postoperatively by ocular response analyzer (ORA) and the posterior elevation difference (PED) was measured by Pentacam.
RESULTS: After operation, IOP, CH, CRF, and PED were statistically different among the three groups (F=12.99, 31.148, 23.998, all P<0.0001). There was no statistically significant difference in IOPcc among the three groups (F=0.603, P>0.05). The IOP, IOPcc, CH, and CRF were statistical changed after surgery (F=699.635, 104.125, 308.474, 640.145, all P<0.0001). The PED of Group I was significantly higher than that of Group II (P<0.05), and Group II was significantly higher than that of Group III (P<0.05). The PED value of 3mo after surgery decreased in each group compared with 1mo after surgery, but there was no statistical difference (Group I: t=0.82, P=0.41; Group II: t=0.17, P=0.87; Group III: t=1.35, P=0.18). The correlation analysis of corneal biomechanical parameter changes with PED at 1mo and 3mo after surgery showed that ΔIOP, ΔIOPcc, ΔCH, and ΔCRF were not correlated with PED value in three groups (P>0.05).
CONCLUSION: The smaller the RCST/CT, the greater effect on corneal biomechanics and posterior surface elevation. There is no correlation between changes in corneal biomechanics and posterior corneal surface elevation in the range of RCST/CT≥50%.

Se aborda la ética profesional como elemento que configura específicamente la labor de los docentes, quienes son llamados a generar procesos de cambio, en consonancia con los desafíos sociales y las necesidades del contexto y los estudiantes, a orientar una práctica formativa en valores en la que se destaque la solidaridad, el respeto, la tolerancia, la justicia y la autenticidad en sus actos, bases para constituir al docente en modelo o ejemplo para sus discípulos considerando que la ética profesional docente son las actitudes del profesional en educación respecto al cumplimiento de sus derechos y deberes bajo unos valores, principios y hábitos propios de la práctica docente. Este ejercicio se debe hacer con reflexión y autorreflexión en donde constantemente se delibere sobre la actitud moral de sí mismo y profesional. Los diferentes hallazgos demuestran la necesidad e importancia de potenciar en docentes en formación su ethos profesional para mejores resultados en los educandos en todos los aspectos. El recorrido conceptual registra la importancia de la ética profesional desde la formación docente, proceso en que se hace necesario consolidar la sensibilidad ética y ciudadana de modo que guie el ejercicio docente y contribuya a la responsabilidad social para el bienestar institucional.
Produktywność a ekspansja międzynarodowa przedsiębiorstw. Przypadek województwa łódzkiego
Authors: Gabrielczak Piotr , Serwach Tomasz
Published: October 2023

W artykule przedstawiono wyniki badań nad związkami między produktywnością firm z województwa łódzkiego a ich ekspansją zagraniczną w postaci eksportu, importu dóbr kapitałowych lub pośrednich oraz bezpośrednich inwestycji zagranicznych (BIZ). Wykazano, że firmy zaangażowane w działalność międzynarodową są bardziej efektywne – w szczególności najbardziej produktywne są firmy posiadające BIZ. Przetestowano dwie podstawowe hipotezy zaczerpnięte z modeli tak zwanej Nowej Nowej Teorii Handlu: hipotezę o samoselekcji (wysoka produktywność prowadzi do internacjonalizacji) oraz hipotezę o uczeniu się (internacjonalizacja prowadzi do wzrostu produktywności). Udało się znaleźć dowody na występowanie samoselekcji przedsiębiorstw. Z kolei wyniki dotyczące uczenia się przez umiędzynarodowienie okazały się nieistotne statystycznie. Jednocześnie – z uwagi na pewne wady dostępnych danych – istnieją przesłanki, na podstawie których hipotezy o uczeniu się nie powinno się jednoznacznie odrzucać.

Climate change can negatively influence hop yield and its quality. Cultivation areas limited by the prohibition of using water from small water sources are most at risk. In order to prevent these areas from completely disappearing in the future, planting hops with varieties or genotypes tolerant to drought could be a promising solution. Therefore, Czech hop breeding targets drought-tolerant genotypes with high crop yield and stability of quantitative and qualitative parameters which will also be well-usable in the Czech brewing industry. Twelve promising genotypes (5165 (Uran), 5194, 5304, 5348, 5398, 5432, 5461, 5464, 5465, 5646, 5669, and 5693) were selected after measurement of their physiological parameters and their basic chemical and sensorial properties were determined. Simultaneously, they were assessed from the point of view of brewing quality using sensory and chemical analysis using a brewing test. For this purpose, experimental beer using identical decoction single-hopped technology, where a hop aroma was highlighted using hopping in a whirlpool was prepared. The results show that three genotypes belong to the category of bitter varieties (5165, 5194, and 5304), whereas the other are genotypes exhibiting the character of aromatic varieties. From a grower’s point of view, genotypes 5165 (Uran), 5194, 5348, 5398, and 5461 show a very high yield. The overall impression of all beer samples is very good, bitterness is fine in most samples and hop aroma is mostly hoppy, herbal, woody, spicy, and in some cases also fruity (5304, 5461, 5465, 5646, and 5693).
Steppe Eagle’s population structure migrating through the bottleneck of Eilat in spring
Authors:   International Birding and Research Center, Weiss N.
Published: October 2023

Steppe Eagles (Aquila nipalensis) migrate in large numbers past key migration flyways from almost its entire breeding region. On its spring migration route from Africa many birds fly through the bottleneck of Eilat in southern Israel. Migration timing and age structures in the population are often key elements of conservation works. In the four springs of 2015 to 2018 we systematically counted the passing Steppe Eagles at two count stations. An average of 15,039 Steppe Eagles were counted per spring. We also recorded the ages of many of the Eagles. We found patterns in the Eagle's migration that is related to the age of the eagles. Adults arrive early and are most abundant, followed by sub adults, and juveniles in timing and numbers. Furthermore, we compared our data of the structure of the passing populations with different flyways and wintering sites and found significant differences. The flyway in Eilat is mostly occupied by adult migrating birds, 72% of the aged birds were adults in the survey. The different usage of flyways by ages can be an important factor in future conservation projects.
