Introduction. Currently, several virtual reality (VR) simulators have been described for the upper urinary tract stone surgery skill development, including retrograde or antegrade nephroscopy. However, their high cost and the lack of a detailed reconstruction of the intraluminal pelvicalyceal system (PCS) appearance limit their implementation into educational process and clinical practice.

Objectives. To develop the approach for VR-reconstruction of the intraluminal appearance of the PCS via head mounted device (HMD), as well as estimate its usefulness for novices to improve spatial orientation during retrograde flexible nephroscopy.

Materials & methods. Five residents without experience in self-performing retrograde flexible nephroscopy participated in a 7-day training course on the VR simulator developed, during which each novice studied six variants of the PCS. For the procedure simulation, a silicone kidney model was created with the stone placed in the calyx which was selected randomly in each case. Before and after VR-course, each resident assisted the experienced urologist during simulated retrograde nephroscopy to find the stone placed according to random selection. The nephroscopy time and the number of errors in stone-finding during retrograde flexible nephroscopy were analysed.

Results. There was a statistically significant decrease in nephroscopy time (on avg by 17.6 minutes, p = 0.043) and errors to find targeted calyx, which was observed once after the training one resident only.

Conclusion. The described VR simulator does not require significant time, technical and financial costs, and is available for wide implementation in the training of young specialists.
Pathological findings in semen analysis from COVID-19 survivors and the impact of various SARS-COV-2 vaccines on spermatogenesis
Authors: Ibishev Kh. S. , Prokop J. O.
Published: April 2023

Male reproductive health depends on many factors, including whether infectious diseases occur in the reproductive system. Such changes may be reflected in the semen analysis. In the past three years, the number of individuals who fell ill with COVID-19 caused by SARS-CoV-2 has been growing worldwide, including in Russia. This infection causes dysfunction and a negative effect on many organs and systems, including reproductive organs, which is reflected in abnormal semen parameters. Despite the high efficacy and small number of side effects found in clinical trials, only 56% of the population in the US and 49% in the Russian Federation reported wanting the vaccine. One of the reasons for distrust of vaccines is the potential negative impact on fertility. A literature review is devoted to the study of the effect of SARS-CoV-2 and vaccination on male reproductive health. The search was carried out using Medline, PubMed, and EMBASE databases.
Ejaculation-sparing enucleation of benign prostate hyperplasia: is it almost feasible?
Authors: Martov A. G. , Ergakov D. V. , Asliev K. A. , Baykov N. A.
Published: April 2023

Introduction. Patients often request maintenance of antegrade ejaculation, and try to find the clinic, surgeon, and treatment to store it. Despite an established technique, the long-term results of ejaculation-sparing operations at a large prostate volume remain unstable. This is not allowed to give patients a guarantee in maintaining this component in their sexual life.

Objective. To evaluate the frequency of ejaculation maintenance after laser ejaculatory-sparing prostate enucleation.

Materials & methods. Since 2017 ejaculation-sparing laser enucleations have been performed in prostate volume (V pr > 80 cc) in 84 patients. Fifty-four patients (64%) had three lobes benign prostate hyperplasia (BPH) and two lobes — 30 patients (36%). Preoperative voiding parameters were IPSS score — 21.0 ± 2.7, QoL — 4.8 ± 0.6, residual urine volume (V res) — 139 ± 43 mL, Q max — 8.1 ± 2.0 mL. We estimate the result as positive if antegrade ejaculation remained after intervention. If ejaculation volume decreased, then as partially positive and negative — ejaculation was absent postoperatively. We conducted questionnaire and follow-up examination 3 – 6 months after intervention.

Results. Thulium-fiber laser enucleations have been performed in all cases without any serious complications. Followup 3 – 6 months after operation showed V pr — 29 ± 4 cc, V res — 19 ± 17 mL, Q max — 19.1 ± 3.1 mL/sec. IPSS score — 8.1 ± 1.9 and QoL — 2.6 ± 0.7. There are the following technical remarks: 1) tissue-sparing in the verumontanum; 2) no or minor mechanical tissue tension during enucleation; 3) avoid additional resection in the bladder neck; 4) refuse total coagulation; 5) no urethral catheter tension after operation; 6) catheter balloon inflow only in the bladder, not in the fossa. Antegrade ejaculation has stored at 17 (20%) patients, partial ejaculation — at 34 (40%) patients, so overall efficacy is 60%. The presence of a median lobe is shown to be negative prognostic factor due to the absence of full antegrade ejaculation in all cases. A partial ejaculation was achieved at 21 patients. Based on the obtained results we have optimized the three-lobe prostate enucleation technique. Four from our initial 7 patients had full storage of ejaculation and 3 — partial.

Conclusion. The possibility of BPH laser surgery to store ejaculation function at the request of the patients is modest. The presence of the median lobe makes the full ejaculation-sparing impossible. In cases of two lobes BPH full storage of the ejaculation was at 57% and partial at 43%, respectively. The following evaluation of the described technique is mandatory.

Introduction. Patients with bilateral nephrolithiasis are a challenge for the treating physician. Therefore, such patients traditionally are subject to phased surgery to reduce the rate of complications. At the same time, the enhancement of endoscopic technologies and anesthesia makes it possible to perform surgical treatment of bilateral nephrolithiasis simultaneously.

Objective. To evaluate the effectiveness and safety of performing simultaneous bilateral percutaneous nephrolithotripsy (PCNL).

Materials & methods. The main group comprises 19 patients (avg age 45.0 ± 2.25 years) suffering from bilateral nephrolithiasis (13 men and 6 women). The control group include 20 patients (avg age 45.80 ± 2.29 years) suffering from bilateral nephrolithiasis. Main group patients underwent simultaneous bilateral mini-PCNL, control group patients — staged PCNL within two hospitalisations. The visual analogue scale (VAS) was used to assess the pain severity. Patients noted subjective pain sensations on post-op days 1 and 3. QoL indicators were assessed using the SF-36 general questionnaire, as well as the Russian-language validated version of the WISQoL questionnaire.

Results. There were no statistically significant differences between the parameters (the difference between the hemoglobin before and after mini-PCNL was 12 g/l; between the serum creatinine was 18 µmol/l). There was a decrease in total surgery time (121.0 ± 6.1 min) for main group patients compared to (147.0 ± 7.3 min) control group patients (total surgery time during the first and second hospitalisations) and a reduction in hospital stay (4.50 ± 0.23 days) for main group patients compared to control group patients (10.0 ± 0.5 days). Complications observed by us in the two groups were comparable. The valuesobtained on the SF, RE and MH scales in main group patients were higher both on post-op day 1 (67.9 ± 3.39; 56.90 ± 2.85 and 63.80 ± 3.19, respectively) and post-op day 3 (86.80 ± 4.34; 83.70 ± 4.19 and 82.50 ± 4.13, respectively) compared to control group patients during the first and second hospitalizations. Statistically significant differences were also recorded according to the grades "Social functioning" and "Emotional influence" in main group patients (80.90 ± 0.26 and 82.6 ± 0.19, respectively).

Conclusion. Simultaneous bilateral mini-PCNL is safe and effective in well-selected patients.

Published: April 2023

El 15 % de los suelos del mundo están en proceso de degradación física y química y una de sus causas es por la salinidad. En la cuenca del río Guayas, Ecuador, sus suelos presentan este tipo de deterioro, la cual fue la razón para este estudio, cuyo objetivo fue determinar la salinidad de agua y suelo, y la caracterización de los de los sistemas de producción de arroz de San Jacinto de Yaguachi, provincia del Guayas. En las 19.027 hectáreas analizadas, se georreferenciaron 99 puntos de muestreo para los análisis del suelo y para el agua de riego se seleccionaron 10 sitios para análisis químico. En el diagnóstico de los spa se consideraron 2235 unidades de producción agropecuaria (upa) y se aplicaron 113 encuestas usando estadísticas descriptivas, donde luego las 51 variables fueron analizadas con Infostat. Del área de estudio, 6.533,87 ha presentaron problemas de salinidad, lo cual se asocia al uso indiscriminado de fertilizantes químicos sin orientación de análisis de suelo y agua, debido a que el 89 % aplica fertilizantes inorgánicos, lo que genera contaminación. Se concluye que tanto el suelo como el agua son limitantes relevantes para la producción de arroz en el cantón de San Jacinto de Yaguachi, ya que los suelos son vertisoles, de textura arcillosa y con un pH de 6,9 (neutro); sin embargo, la conductividad eléctrica (ce) de 4 dS.m-1 se relaciona con el porcentaje de sodio intercambiable (psi) en el orden del 7,93 %. Por otro lado, el agua para riego tuvo un ce de 2,64 dS.m-1, es de categoría C4S3 y es dura y de salinidad alta.

Published: April 2023

BACKGROUND

The increasing prevalence of diabetes is placing important demands on the Chinese health care system. Providing self-management programs to the fast-growing number of people with diabetes presents an urgent need in rural primary care settings in China. Peer support has demonstrated effectiveness in improving self-management for individuals with diabetes in urban communities in China. A priority then becomes developing and evaluating a peer support program in primary care settings in rural communities of China and determining whether it is feasible and acceptable.

OBJECTIVE

The aims of this study are (1) to evaluate the feasibility and acceptability of a peer support approach to type 2 diabetes self-management in rural primary care settings; (2) to identify enabler and facilitator factors likely to influence the peer support implementation; (3) to provide primary data and evidence for developing a version of the program suitable for a randomized controlled trial in rural primary care settings.

METHODS

Three townships will be sampled from 3 different counties of Anhui province as the study setting. Participants will be recruited based on these counties’ local primary care health record system. The peer supporters will be recruited from among the participants. The peer support program will be led by peer supporters who have completed 12 hours of training. It will be guided by primary care providers. The program will include biweekly meetings over 3 months with varied peer support contacts between meetings to encourage the implementation of diabetes self-management. Mixed methods will be used for evaluation. Qualitative methods will be used to collect information from health care system professionals, individuals with diabetes, and peer supporters. Quantitative methods will be used to collect baseline data and data at the end of the 3-month intervention regarding psychosocial factors and self-management practices.

RESULTS

The results will include (1) quantitative baseline data that will characterize type 2 diabetes self-management practices of individuals with diabetes; (2) qualitative data that will identify enablers of and barriers to self-management practices for individuals with type 2 diabetes in rural communities; (3) both qualitative and quantitative evaluation data, after the 3-month intervention, to demonstrate the feasibility and acceptability of the peer support approach for individuals with type 2 diabetes.

CONCLUSIONS

Our findings will inform the design of a tailored intervention program to improve self-management among individuals with type 2 diabetes in rural primary care settings. If we find that the peer support approach is feasible and acceptable, we will develop a larger randomized controlled trial to evaluate effectiveness in multiple rural settings in the province.

Authors: Nisitasari Anindhita , Rokhman Nur
Published: April 2023

The COVID-19 pandemic that has occurred has received worldwide attention due to the rapid rate of transmission of the outbreak and the large number of deaths that occurred. The aim of this study is to build the SVEAuAdIR model , determine the transmission of COVID-19 in Indonesia by forecast the spread of the disease, and determine the effect of vaccination by looking at the basic reproduction number  of SVEAuAdIR model. The results obtained from MAPE on the model are 12%. So it can be said that the SVEAuAdIR model is good for prediction models for the spread of COVID-19. The situation where there are no more individuals infected with COVID-19 is called COVID-19 disease free, thus it is predicted that Indonesia will be free of COVID-19 on October 7, 2021. The target of the Indonesian Ministry of Health is that by the end of 2021 the spread of COVID-19 can be stopped . However, on October 7, 2021, judging from the actual data during this research, there were still new cases of COVID-19. On that day there were 1393 new cases infected with COVID-19. Thus, showing that Indonesia's target of being free of COVID-19 disease by the end of 2021 has not been achieved. The  number of the SVEAuAdIR model is in the range of values , which means that the spread of disease is close to disease-free. Based on the results of the  value of the SVEAuAdIR model, this study concluded that vaccination could reduce the spread of COVID-19 compared to those who did not vaccinate

The problem with mushroom cultivation is the difficulty of regulating the room temperature of mushrooms, especially oyster mushrooms. The optimal production of oyster mushrooms is at temperatures between 25 C - 27 C. To regulate or manipulate humidity and room temperature to water the kumbung or mushroom room. The watering process is carried out several times to stabilize the room temperature during the day.To overcome the watering that is done manually, Automatic Temperature Control and Monitoring of Oyster Mushrooms Based on GSM Sim800l Arduino Uno is made. This tool uses a DHT11 sensor, relay, 16x2 LCD, GSM Sim 800L, and Stepdown. The test was carried out in a mushroom kumbung measuring 10.7m long, 5.9m wide, and 3.5m high. Watering time is done by observing the data at room temperature. The data is then studied using a backpropagation. This method aims to identify the pattern of watering time so that the optimal watering time is produced. The test results show that the tool can monitor the temperature and humidity of the kumbung mushroom with the following values: temperature 27°C - 33°C and humidity 70% - 90%. The introduction of mushroom watering patterns with BPNN showed an error rate of 40%.

Background

IgA nephropathy can progress to kidney failure, and risk assessment soon after diagnosis has advantages both for clinical management and the development of new therapeutics. We present relationships among proteinuria, eGFR slope, and lifetime risks for kidney failure.

Methods

The IgA nephropathy cohort (2299 adults and 140 children) of the UK National Registry of Rare Kidney Diseases (RaDaR) was analyzed. Patients enrolled had a biopsy-proven diagnosis of IgA nephropathy plus proteinuria >0.5 g/d or eGFR <60 ml/min per 1.73 m2. Incident and prevalent populations and a population representative of a typical phase 3 clinical trial cohort were studied. Analyses of kidney survival were conducted using Kaplan–Meier and Cox regression. eGFR slope was estimated using linear mixed models with random intercept and slope.

Results

The median (Q1, Q3) follow-up was 5.9 (3.0, 10.5) years; 50% of patients reached kidney failure or died in the study period. The median (95% confidence interval [CI]) kidney survival was 11.4 (10.5 to 12.5) years; the mean age at kidney failure/death was 48 years, and most patients progressed to kidney failure within 10–15 years. On the basis of eGFR and age at diagnosis, almost all patients were at risk of progression to kidney failure within their expected lifetime unless a rate of eGFR loss ≤1 ml/min per 1.73 m2 per year was maintained. Time-averaged proteinuria was significantly associated with worse kidney survival and more rapid eGFR loss in incident, prevalent, and clinical trial populations. Thirty percent of patients with time-averaged proteinuria of 0.44 to <0.88 g/g and approximately 20% of patients with time-averaged proteinuria <0.44 g/g developed kidney failure within 10 years. In the clinical trial population, each 10% decrease in time-averaged proteinuria from baseline was associated with a hazard ratio (95% CI) for kidney failure/death of 0.89 (0.87 to 0.92).

Conclusions

Outcomes in this large IgA nephropathy cohort are generally poor with few patients expected to avoid kidney failure in their lifetime. Significantly, patients traditionally regarded as being low risk, with proteinuria <0.88 g/g (<100 mg/mmol), had high rates of kidney failure within 10 years.
Cash Demand and Financing Decisions

Published: April 2023

Recent literature starts to focus on the effects of the urgency of cash demand on the choice of financing sources. Extant studies use data from the U.S. and conclude that firms use debt financing to meet immediate cash demand and equity financing to meet longer-term cash demand. Using data from China, this paper uncovers opposite findings: Firms are more likely to use equity financing to meet immediate cash demand and debt financing to meet cash demand in longer terms. We discuss the possible mechanisms behind the pattern.
An excursion regarding women's impediments in Austen's Pride and Prejudice
Authors: Ritika Ritika
Published: April 2023

Pride and Prejudice is a novel of manners. In the novel Jane Austen characterises the complex conditions of women in nineteenth-century England. A woman's happiness is associated with marriage. Her social status is being guided by a man whom she chooses as her husband. Happiness and love are the secondary themes in the marriage, what carries weight is the wealth and the property of the man or groom. A woman tries to mould her identity at the optimum level to deem fit for married apparel because unmarried daughters are considered a burden on their parents. Women's priorities and choices are often ignored. The patriarchal civilization has always dominated the female counterparts through their authoritative voices. Women play a submissive role in society, their voices are crushed and they are compelled to follow in the footsteps of their husbands and fathers. In the novel, there is not a single self-made woman. All women are tied to societal constraints.

En las diversas etapas del desarrollo, los organismos están expuestos a distintas disposiciones ambientales que tienen injerencia sobre su estado de salud, evidenciando la influencia de los patrones alimentarios sobre la aparición de enfermedades asociadas al incremento del peso corporal. No obstante, no solo ello es determinante, también las circunstancias intrauterinas en las cuales se desarrolla el organismo juegan un papel fundamental en su presencia de patologías. Un ejemplo de lo anterior son los efectos post-privación, dado que la privación de alimento genera alteraciones en el peso corporal; por lo que resulta de interés evaluar sus efectos en una etapa prenatal (i.e., la gestación).  Para tal fin durante cinco fases, dieciséis ratas albinas de la cepa Wistar fueron asignadas a dos grupos (experimental y control) cada uno con 8 sujetos, fueron expuestas a condiciones de libre acceso seguidas de privación de alimento. Como condición previa al inicio del experimento las crías del grupo experimental, fueron expuestas a privación de alimento durante la gestación; mientras que las del grupo control a condiciones ad libitum durante la misma etapa. Los principales resultados muestran que los efectos post-privación se replican utilizando privación intrauterina, sin embargo, en condiciones intrauterinas aumenta la adaptación a privaciones futuras. Con base en esto, es posible señalar que la historia de privación del grupo experimental fue un importante factor que generó una adaptación ante futuras en los ciclos privación-realimentación.

Published: April 2023

Abstract: Any nation's financial growth is largely determined by its availability of energy. The rapid expansion of the manufacturing, automobile, and residential sectors over the preceding few decades led to an increase in global electricity consumption. For electrical vehicles to be safe, they need a Battery Management System (BMS), which controls the electronics of a chargeable battery. The consumer and the battery are both safeguarded by ensuring that the mobile phone operates within its safe operating parameters. The battery's State of Health (SOH) is displayed on the BMS video display, which also collects data, controls external factors that have an effect on the mobile phone, and balances them to maintain a consistent voltage across all cells. It might have more features and capabilities to provide information about the battery's energy state. The tool can intelligently conserve energy by utilizing these facts. In this project, work was done using a system learning method to find the voltage that was exceeded while the battery was being charged. Because it only has a battery and an electric motor rather than a combustion engine and gas tank, the structure of an electric car is simpler and easier to control at the factor level. Instead of charging the entire battery collection, we will identify the battery that needs to be charged. This will allow us to save you from having to replace dead batteries and may also prevent damage from occurring to them. We can ensure that the batteries are charging and discharging appropriately by anticipating the issue using the available datasets.

La profesionalización genera un alto impacto en la competitividad de las empresas, aún más en empresas familiares donde estos procesos son especialmente complejos. Esta investigación buscó determinar cuáles son los determinantes del éxito de procesos de profesionalización de empresas familiares. Sobre la base de la opinión de expertos del ámbito académico, asesoresconsultores de empresas familiares y empresarios que han vivido este tipo de procesos, se logró determinar que las variables que más explican el éxito en este tipo de procesos son la capacidad de adaptarse a los cambios y el control de los procesos de profesionalización. Por otra parte, las variables que menos explican este fenómeno son la capacidad de compartir tareas por parte del propietario y la incorporación de ejecutivos no familiares por medio de procesos competitivos. Esta investigación reafirma las variables encontradas en la literatura y adicionalmente propone un modelo factorial que las agrupa y relaciona de forma más precisa mejorando su comprensión. Futuros estudios podrían profundizar el estudio de este fenómeno, mejorando el tamaño y representatividad de la muestra y estudiando el impacto de variables como la cultura o el tipo de industria. AbstractThe professionalization creates a high impact on the business competitiveness, in particular on family businesses where these processes are particularly complex. This research aimed at identifying the determinants of success in the family businesses professionalization process. Based on the opinions of academic staff, consultants, family business’ managers and entrepreneurs who have experienced this type of process, it was determined that the variables that explain the most the success of this type of process are the ability to adapt to changes and the control of the processes. On the other hand, the variables that explain the least are the ability to share tasks by the owner and the incorporation of non-family executives through competitive processes. This research confirms the variables found in the literature and additionally proposes a factorial model that groups these variables in a more precise and understandable manner. Further studies may try to gain a better and deeper understanding of this phenomenon, improving the sample’s size and representativeness and investigating the impact of variables such as culture or the type of industry.

El sistema de innovación del Perú: caracterización en base a un modelo estructurado en función de tres niveles operacionales
Authors: Ísmodes Eduardo , Carpio Ojeda Jesús
Published: April 2023

El presente trabajo se concentrará en determinar las características generales del sistema de innovación en el Perú, para luego proponer un modelo estructurado de tres niveles: Político, Operacional y de Generadores de Investigación, Desarrollo, Innovación y Emprendimiento (I+D+i+e). Destaca el que estos tres niveles están orientados a la búsqueda de la generación de la innovación. Se considera que la innovación se produce principalmente en la relación entre las empresas y organizaciones que tienen contacto directo con las necesidades y requerimientos de la sociedad (el mercado). Para ello, se requiere el involucramiento, la cooperación y la participación de todos los involucrados: estado, empresa y academia de manera horizontal y orientada por resultados.

Política de desenvolvimento industrial da Paraíba e emprego no setor de calçados como alternativa de ocupação da mão-de-obra de baixa qualificação nos municípios afetados pela seca
Authors: Goés Moutinho Lúcia Maria
Published: April 2023

O artigo contém uma avaliaçao da política industrial da Paraíba como instrumento de combate à pobreza através de geração de vagas de trabalho em áreas carentes. A questão que este estudo procura responder é se a política industrial da Paraíba, baseada em incentivos fiscais / financeiros, tomou prioritariamente a direção dos municípios localizados no polígono da seca. Para tanto, faz-se uma análise exploratória da geografia do emprego industrial no Estado a partir do uso de coeficientes de localização calculado por segmentos do setor industrial e por municípios do estado com base nos dados da RAIS/MTB=2001. Posteriormente, faz-se a seleção dos municípios com maior concentração de emprego na indústria de calçados por ser este o segmento que reune os dois predicados requeridos para este artigo, ou seja, é um dos segmentos que mais recebe incentivo governamental e o que mais emprega. As empresas implantadas ou revitalizadas através dos incentivos foram estudadas através de pesquisa direta encomendada pelo SEBRAE em novembro de 2002 à UFPB.Os principais resultados obtidos apoiam a hipótese de que política de emprego caminhou em direção contrária às regiões mais pobres ao mostrar que: as empresas situadas à oeste do Estado, em geral micro e pequenas empresas locais, foram modestamente contempladas pela política; as principais beneficiárias foram as grandes e médias empresas implantadas no brejo e litoral; e, que os principais motivos dessa distribuição geográfica encontram-se no fato de ser, para as micro e pequenas empresas, mais vantajoso a clandestinidade do que os benefícios dos incentivos governamentais e, no que tange as grandes e médias empresas, ser a localização um determinante importante do sucesso de sua estratégia agressiva de minimização de custos.

Published: April 2023

Este estudio trata del análisis de las relaciones entre el clima organizacional y la autoeficacia, en grupos de trabajo formados por profesores y/o investigadores que trabajan en un departamento de una universidad.La muestra del presente estudio está compuesta por profesores e investigadores miembros de 59 grupos de trabajo (departamentos), 23 de universidades españolas y 36 de universidades chilenas, 30 de universidades privadas y 29 de universidades públicas.Para lograr los objetivos descritos se procedió a la aplicación del instrumento elaborado (Chiang, 2003) para la recolección de los datos. El instrumento consta de 49 ítems repartidos en siete escalas para medir el clima organizacional y una escala para medir autoeficacia. Los resultados obtenidos muestran que el instrumento utilizado entregó, para las muestras del presente estudio, una fiabilidad adecuada en cada una de las escalas que componen este cuestionario.Sobre la relación entre las dimensiones del clima organizacional y la autoeficacia concluimos que, los profesores que perciben una mayor libertad para tomar sus propias decisiones (empowerment), un mayor consenso con la misión de su universidad y un mayor interés por el aprendizaje de sus alumnos se sienten más capaces para cumplir su tarea docente (autoeficacia). En la mayoría de los casos los docentes que perciben un clima de mayor libertad de cátedra, mayor interés por la investigación y el estudio y mayor afiliación, también se sienten más capaces de realizar su tarea (autoeficacia). Además, solamente en las universidades privadas, la variable de clima organizacional presión laboral, esta relacionada negativamente con la autoeficacia.Por lo que respecta a las diferencias entre departamentos, en los departamentos de las Universidades Privadas españolas existe mayor presión laboral. En los departamentos de las Universidades Privadas chilenas existe mayor interés por el aprendizaje de los estudiantes, mayor presión laboral y mayor autoeficacia.
Un análisis descriptivo de la relación entre el proceso de aprendizaje organizacional y las ventajas competitivas
Authors: Barra Salazar Ana María
Published: April 2023

El presente paper es de origen descriptivo cuyo objetivo se centra en mostrar el campo del Aprendizaje Organizacional en el sentido de los términos relacionados con éste y que hasta el día de hoy no existe consenso entre los autores en definir los límites de cada uno de ellos, y al mismo tiempo visualizar el origen o raíces de las Ventajas Competitivas.En el caso del proceso de Aprendizaje Organizacional se desarrollan de manera incipiente algunos modelos que relacionan los conceptos de aprendizaje organizacional y ventajas competitivas; ideas que se desarrollarán en un segundo artículo de la autora.El contexto en que se trabajará será el siguiente: se revisarán los conceptos y sus relaciones con el fin abordar y tener una visión general de los tópicos en cuestión. Sin embargo, previo a esto hay que entender que el aprendizaje organizacional (AO), es un proceso y como tal tiene algunos conceptos que se relacionan; importante será abordarlos para explicar las diferencias. Estos conceptos son: la “Administración del Conocimiento”, “la Organización que Aprende” y el “Conocimiento Organizacional”.
O invisível no visível: a questão filosófica de Deus e da carnalidade no pensamento de Maurice Merleau-Ponty
Authors: Mara Rodrigues Silva Patrícia
Published: April 2023

O texto de Patrícia Silva é “particularmente original e, portanto, interessante para o campo da filosofia da religião. A autora nos convida a uma revisitação aos textos de Merleau-Ponty, onde encontramos uma questão mais do que urgente: uma reflexão filosófica que assuma a tradição cristã sem se servir das expressões da dogmática tradicional. Inspirada pelo pensamento do mestre, a filósofa lida de maneira magistral com o paradoxo inexorável a respeito da carne e de Deus, oferecendo, por meio de sua obra, um intrigante acesso a essa candente problemática de fundo, quando insiste na tentativa de se dizer Deus fora das malhas dos falsos absolutos.

CEL: Celem artykułu jest zbadanie możliwości objęcia ochroną ubezpieczeniową osób z chorobami cywiliza- cyjnymi w oparciu o rozwiązania stosowane przez zakłady ubezpieczeń na życie w Polsce. Coraz więcej ludzi choruje przewlekle, a schorzenia te mają niewątpliwie wpływ na poziom ryzyka przyjmowanego do ubezpie- czenia. Aby zapobiegać zupełnemu wykluczeniu osób chorujących na choroby cywilizacyjne z segmentu ubezpieczeń, rynek powinien stworzyć takie produkty ubezpieczeniowe, które przy jednoczesnym zachowa- niu opłacalności umowy dla ubezpieczyciela spełnią również podstawowe wymagania zabezpieczenia życia osób ubezpieczonych. METODA: W artykule dokonano przeglądu literatury dotyczącej tendencji związanych z występowaniem chorób cywilizacyjnych w Polsce na tle tendencji europejskich. Na podstawie informacji zawartych w ogólnych warun- kach ubezpieczenia wybranych produktów ubezpieczeniowych przeprowadzono analizę porównawczą tych ofert pod kątem uwzględnienia w nich schorzeń cywilizacyjnych. WYNIKI I WNIOSKI: Z przeprowadzonej analizy wynika, że dla osób dotkniętych chorobami cywilizacyjnymi istnieją znaczne trudności w uzyskaniu adekwatnej ochrony ubezpieczeniowej. W odniesieniu do najczęściej występujących chorób układu krążenia czy też nowotworów ubezpieczyciele uwzględniają te schorzenia w swojej ofercie, jednak wciąż istnieje luka w przypadku schorzeń takich, jak: cukrzyca, alergie czy zaburze- nia psychiczne. ORYGINALNOŚĆ I WKŁAD: Wstępne wyniki badania przedstawione w artykule sygnalizują konieczność mo- dyfikacji dotychczasowego podejścia do oceny ryzyka w ubezpieczeniach na życie poprzez uwzględnienie dynamicznego charakteru chorób cywilizacyjnych, co daje szanse na poszerzenie oferty produktowej. Pro- ponuje się zastosowanie monitoringu stanu zdrowia ubezpieczonych, chociażby z wykorzystaniem nowocze- snych technologii, co, choć jest w praktyce dyskusyjnym narzędziem, stwarza możliwość lepszego zarządza- nia ubezpieczonym ryzykiem oraz posiada walory profilaktyki zdrowotnej.
