Authors: Singh Maninder , Jaswal Anita , Sarkar Shimpy , Singh Arshdeep
Published: May 2023

Background: Maize is one of the best cereal crop as it is also known as “Queen of cereals” by giving good taste, having more hybrid varieties, good production and price also. But to make maize best cereal well fertile and neutral soil is important. In the several previous years tthere was good soil, plant and environment relationship but due to passing the time soil health was deteriorated by using the more amount of inorganic fertilizers (beyond the limit). The insect pest attack was also increased due to uses of more amount of fertilizers. Soil becomes topic in nature and most of the inorganic chemical leached down and mixed with the water table. Material: The two year field experiment was conducted at experimental farm at Lovely Professional University Phagwara Punjab during the kharif season 2019- 2020 to study the influence of integrated use of organic manures and inorganic fertilizers on physio-chemical properties of soil and yield of kharif maize in coarse loamy Typic Haplustept soil with 8 treatments treatments T1- Control, T2 - RDF (125:60:30) kg ha-1, T3- RDF +10 ton farmyard manure ha-1, T4- 75% RDF + 10 ton farm yard manure ha-1+ Vermicompost @2 ton/ha, T5-75% RDF +10 ton farmyard manure ha-1, T6- 50% RDF +10 ton farm yard manure + vermicompost@2 ton ha-1 + azotobacter ha-1, T7-50% RDF +15 ton of farmyard manure +azotobacter ha-1, T8-25 % RDF + azotobacter + vermicompost@ 2 ton ha-1 in RBD design with 3 replications. Result: The soil pH was found highest in T2 (RDF (125:60:30) kg ha-1) (7.8) whereas highest EC was found in T6 (50% RDF +10 ton farm yard manure + vermicompost@2 ton ha-1 + azotobacter ha-1) (0.27 dsm-1). The highest bulk density found under T1 (Control) ( 2.02 gcm-3) and porosity was highest in T8 (25 % RDF + azotobacter + vermicompost@ 2 ton ha-1) (37.96%). In T6 (50% RDF +10 ton farm yard manure + vermicompost@2 ton ha-1 + azotobacter ha-1), the highest amount of Nitrogen (412.3 kgh-1), phosphorus (67.77 kgh-1), potassium (884.3 kgh-1) and organic carbon (0.567%) was found. In terms of yield parameters, the grain yield (4223 kgh-1), straw yield (6266 kgh-1), harvest index (41.53%) and 1000- seed weight (366.86gms) was found highest in T6 ((50% RDF +10 ton farm yard manure + vermicompost@2 ton ha-1 + azotobacter ha-1). There are significant difference in all the treatements with respect to the physio-chemical properties of soil and yield paramters of maize.

Authors: Mora-Alvarado Darner A.
Published: May 2023

En el presente estudio se aborda el impacto de la crisis sanitaria causada por la COVID-19, cuyo agente causal es el virus SARS-CoV-2, en 191 países seleccionados, según la información de la plataforma virtual “datosmacro.com”. Para cumplir con el objetivo se utilizaron los indicadores de casos confirmados, muertes, letalidad y las tasas de muertes por COVID-19 por millón de habitantes.
El análisis de los datos al 29/08/2022, indican que los datos de muertes absolutas por COVID-19 por país, no es el más adecuado para valorar el impacto de la crisis sanitaria en forma comparativa entre las naciones. Por su parte, las tasas de letalidad equivalentes a las muertes por COVID-19 entre el total de casos confirmados por el SARS-CoV-2, es un buen indicador, pero depende en mucha de la capacidad de los sistemas de salud de cada país.
En el caso del indicador de muertes de COVID-19/millón de habitantes, a pesar de ciertas debilidades, es el mejor para valorar cuales han sido las naciones más impactadas por la COVID-19 por continentes y en el contexto mundial. Un ejemplo es la comparación entre Perú y los EUA, en donde el país Latinoamericano con una población estimada de 33.396.700 hab, con 215.514 muertes; mientras que EUA con una población de 332.183.000 hab, con 1.043.840 fallecidos, si bien es cierto es la nación con mayor cantidad de fallecidos en el mundo, su tasa de muerte asociadas a la COVID-19/millón de habitantes al 29/08/2022 era de 3.142,36, la cual era menor a la de Perú con 6.463,00. Es decir, esta nación Sudamericana era la más impactada por la crisis de la COVID-19 en el contexto mundial, seguido por Bulgaria, Macedonia del Norte, Bosnia y Herzegovina, Hungría, Georgia, Moldavia, Montenegro, Croacia y Chequia.
Mitigation of human-nature estrangement through pro-environmental behavior in Barbara Kingsolver’s Prodigal Summer
Authors: Arthi R. , Bhuvaneswari V.
Published: May 2023

Humans are designed to live in harmony with nature. As time pass by, people have become increasingly disconnected from nature and have begun to control it, considering it an entirely other entity. Man’s environment-destructive behavior is the reason for the human-nature estrangement in this Anthropocene. Bridging and healing the divide is critical because if it is neglected, the ramifications are unimaginable. Focusing on mitigating the human-nature divide, this article is interested in sketching new directions in Barbara Kingsolver’s Prodigal Summer through pro-environmental behavioral analysis. Pro-environmental behavior is the attitude of humans that promotes a healthy and sustainable environment. It is pertinent to have environmentally responsible behavior for the betterment of the planet because people fail to understand that exploiting nature for their benefit often backfires. There are many approaches to mitigate human-nature estrangement, but using pro-environmental behavior to diminish the dichotomy is feasible and practical. Various studies have analyzed this novel from various perspectives but the present study analyzes the pro-environmental aspects of the novel to blur the human-nature dichotomy.

Authors: Ceko Enriko
Published: May 2023

My goal in conducting the research was to show real links between innovation and knowledge management (knowledge & technology output index) within a quality management approach worldwide in a response to the pandemic and the post-pandemic period. This is because innovation, knowledge, and technology output are becoming important questions related to quality and quality management issues, currently being discussed with increasing interest in a broader perspective from the worldwide audience. They are also part of factors of production theories and enterprise theories too. The research methodology was (1) collecting data and information on the innovation index and knowledge management (knowledge & technology output index) worldwide, (2) describing the newly introduced ISO 56000 family of standards (ISO standards for innovation) and the newly introduced ISO family of standards (ISO standards for knowledge). The method of the research was (1) dealing with descriptive statistics for innovation index and knowledge & technology output and handing (2) correlation and regression analysis (inferential statistics) for relationships between innovation index and knowledge & technology output. This procedure resulted in the main outcome of this research that the relationships between innovation and knowledge & technology output, statistically verified, are strong. Saying this, the general application of ISO standards and specifically, the ISO 56000 family of standards are necessary to achieve a competitive advantage. The key recommendation of the research is that the application of ISO standards and the application of the ISO 56000 family of standards help companies to strengthen their commitment to their customers, improve outcomes of innovation and knowledge & technology output activities, improve processes and procedures and economies around the world to gain a competitive advantage in response to the crisis and post-crisis.

A Study on the Application and Analysis of Chinese Characters and Calligraphy in Avant-Garde Art in China 1980’s - Focusing on Gu Wenda,Wu Shanzhuan , and Xu Bing
Authors:   The Korean Society of Calligraphy, Sur Heui-yeon
Published: May 2023

This study focuses on word and image in Chinese avant-garde art in the 1980s. It focuses on the works of Gu Wenda, Wu Shanzhuan, and Xu Bing. It investigates the significance of their anti-art practice activities in China's political, social, and cultural background in the 1980s. It examines what their activities mean in the history of modern Chinese art. After the end of the Cultural Revolution, a large number of Western ideas flocked to China in the 1980s with reform and opening, and discussions on humanities were held with unprecedented personnel. After the end of the Cultural Revolution, modern artists in China began to accept modern and contemporary Western art from the post-revolution period, and the 85 New Art Movement took place in the mid-1980s, led by young young artists. Artists who participated in the 85 New Wave, China's first modern art movement, organized and worked as an organization and indirectly encountered Western contemporary art and philosophy through books. Their activities contributed to the expansion of Chinese avant-garde art into the nationwide avant-garde movement. The movement contributed to hosting the Chinese Contemporary Art Exhibition in February 1989. Although the exhibition ended ostensibly in failure, the artists who participated in the planning and exhibition later went abroad to study or defect to promote China's visual culture and modern art. In particular, Gu Wenda, Wu Shanzhuan, and Xu Bing. who participated in the 85 new wave, earlier modified, reconstructed, and studied Chinese characters and calligraphy to build their own art world. The purpose of this study is not to honor or criticize the achievements of the three artists' current progressive works. Instead, by looking at examples of works at the beginning of Chinese avant-garde art in the 1980s, we have the opportunity to think about China's historical background and the role of writing art in China's reality in the 1980s.

La problemática de las evaluaciones virtuales en los cursos de matemática
Authors: Pino Romero Neisser
Published: May 2023

Uno de los puntos delicados que suscitó la pandemia del Coronavirus (COVID-19) fue el cambio disruptivo de la educación presencial o semipresencial a la virtual. En esta última modalidad, las plataformas educativas virtuales, como complemento del docente, pasaron a ser el eje central de la transmisión del conocimiento. Esta situación se proyectaba con un crecimiento moderado en los próximos años, pero con la cuarentena total decretada por el Gobierno del Perú en el año 2020, pasó a una transformación rápida de adaptación. En este contexto, la forma de evaluar a los estudiantes en diversos cursos, y en particular, en matemática, cambió rotundamente en lapsos tan cortos con el objetivo de moderar una mejor transición de herramientas virtuales, que mantuvieran la esencia del procedimiento matemático que debe realizar un estudiante para poder validar su aprendizaje. ¿Qué reflexiones podemos compartir?

Published: May 2023

Twelve healthy and not pregnant local cows, aged 3-6 years, 1-3 parity. The cows were synchronized using the PGF2α of 5 ml/cow intramuscularly, twice at 11 days intervals. The Estrus detection based on the scoring of van Eerdenburg was conducted 24 hours after the second prostaglandin injection three times daily for three days. The changes in cervical dilatation were observed at 0, 6, and 12 hours from the onset of estrus. The result showed that 8 of 12 cows were estrus after twice PGF2α injection. All the estrus cows showed mild cervical dilatation with liquid and transparent mucus (opening cervix score 1) at 0-hour observation. Six hours later, 62.50% of cows remained at opening cervix score 1, and 37.50% changed to opening cervix score 2 (optimum cervical dilatation with thick and transparent mucus). At 12 hours after the onset of estrus, 25% of estrus cows had cervical closure (opening cervix score 0, closed cervical with thick and turbid mucus), and 75% changed to opening cervix score 2. In this study, 75% of the cows experienced an optimum open cervix at 12 hours from the onset of estrus. It could be concluded that opening the external cervical canal of local Aceh cows reaches optimum at 12 hours from the onset of estrus.

Pote goats are kept by the rural community in Bangkalan Regency, Madura Island, Indonesia. Estrus symptoms in goats are usually unclear, causing low fertility. This study aimed to determine the intracervical artificial insemination at early and mid-estrus on the Pote does. The 24 the does were randomly divided into two groups and estrous synchronization with PGF2α of 200 µg intramuscularly, twice injections with 11 days intervals. The T1 groups of estrus the Pote does were inseminated at early estrus (0-12 hours). Meanwhile, T2 groups of estrus the Pote does were inseminated at mid-estrus (12-24 hours after signs of estrus appeared. The insemination conducted artificially using post-thawed Boer semen. The observed variables were non-return rate at day 21 post-insemination (NRR21), and pregnancy rate (PR) based on abdominal palpation diagnosis. The result showed that post-thawed Boer buck was qualified (sperm motility more than 40%) for artificial insemination. All of the Pote does were estrus after twice PGF2α intramuscular injection with 11 days intervals. The onset of estrus was 48-72 hours after the second injection PGF2α. The NRR21 and PR ranged from 66.66-100% and 37.50-66.66%, respectively. The NRR21 and PR of the T2 group were higher than those of the T1 group. It could be concluded that intracervical artificial insemination on Pote the does at mid-estrus were more effective, resulting in higher NRR21 and PR than those at early estrus.

This study aims to determine the effect of adding melon (Cucumis melo L.) juice to Lactated Ringer’s-egg yolk extender on the intact plasma membrane (IPM) and morphological abnormalities of native rooster spermatozoa. Five ejaculate each from two native roosters (Gallus gallus domesticus) were divided into four equal volumes. Ejaculate was extended 1:10 (v/v) in Lactated Ringer's-egg yolk without or with the addition of of 2, 4, and 8% (v/v) melon flesh juice, respectively for groups T0, T1, T2, and T3. Extended semen was stored in a refrigerator (5°C) and evaluated every two hours. The results showed that IPM of all groups decreased (p <0.05) consistently, lasting more than 40% for six hours in the T0 and T1 groups and four hours in the T2 and T3 groups. The percentage of spermatozoa morphological abnormalities in all groups stored for six hours was higher (p <0.05) than before storage. However, it was not significantly different (p >0.05) from that which had been stored for two and four hours. It was concluded that native rooster semen extended in Lactated Ringer's-egg yolk without (group T0) or with 2% melon flesh juice (group T1) and stored at 5°C retained spermatozoa plasma membrane integrity of more than 40% and morphological abnormalities of less than 20% for six hours. While the addition of 4 % (T2) and 8% (T3) melon flesh juice maintained the percentage of IPM and spermatozoa morphological abnormalities for only four hours.

Published: May 2023

Introduction: The reduced implementation of surveillance programs and limited bedside infectious diseases consultations due to the pressure of COVID-19 pandemic in healthcare systems led to increased rates of irrational use of antimicrobials and incidence of infections by multidrug-resistant microorganisms. The aim of the present study is to evaluate the incidence of antimicrobial resistance and the management of bloodstream infections before and during COVID-19 pandemic at the University General Hospital of Alexandroupolis (Greece). Material-Methods: This is a retrospective study conducted from January 2018 to December 2022. Data were collected from the University Microbiology Laboratory per semester regarding the isolated strains of Gram positive and negative bacteria in blood cultures and respiratory samples in hospitalized patients in medical and surgical wards and in the Intensive Care Unit (ICU). Additionally, bloodstream infections with requested infectious diseases consultation were reported (n=400), determining whether these were carried out via telephone contact or at the patient's bedside. Demographic data, comorbidities, focus of infection, antimicrobial regimen, duration of treatment, length of hospitalization and clinical outcome were analysed. Results: A total of 4569 strains of Gram positive and negative bacteria were isolated. An increasing trend was reported compared to the pre-pandemic period in the incidence of resistant Gram-negative bacteria, particularly in ICUs. Prior antimicrobial use and the rate of hospital-acquired infections were increased significantly during the pandemic. In the pre-pandemic period 2018-2019, a total of 246 infectious diseases consultations were carried out, while during the period 2020-2022 154, with the percentage of telephone consultations 15% and 76% respectively. Detection of the source of infection and timely administration of appropriate antimicrobial agents were more frequently recorded before the pandemic and 28-day mortality was significantly reduced in cases with bedside consultations. Conclusion: Empowering of infectious diseases surveillance programs and committees, rational use of antimicrobials agents and bedside infectious diseases consultations are vital in order to reduce the impact of infections caused by multidrug-resistant strains.

Ca2+ is a crucial second messenger in plant cells, playing a vital role in various physiological and biochemical processes, including plant growth and development, photosynthesis, and enzyme regulation. Exogenous calcium concentration can have different effects on plant growth. This study aimed to investigate the optimal calcium concentration for the growth of four tree species, namely Pinus tabuliformis, Pinus sylvestris var. mongolica, Populus, and Morus alba seedlings, and whether the optimal calcium concentration varies among different tree species. The study utilized five calcium concentration gradients (0, 100, 200, 400, 800 mg·kg-1) for each species with three repeated treatments. Various growth indexes, photosynthetic parameters, chlorophyll fluorescence parameters, water use efficiency, and antioxidant enzyme activities were assessed to determine each species' calcium concentration requirements. The results showed that exogenous calcium significantly affected the growth and development of each seedling. The growth, biomass, photosynthetic parameters, photosynthetic products, photosynthetic pigments, water use efficiency, and antioxidant enzyme activity all increased initially and then decreased with increasing calcium concentration. Leaf calcium concentration also increased with the exogenous calcium content. Thus, there is an optimal calcium concentration for plant growth, and high or low calcium concentration is not conducive to plant growth. Furthermore, the study found that different tree species have varying optimal calcium concentrations. The optimal calcium concentration for Pinus tabuliformis, Pinus sylvestris var. mongolica, Populus, and Morus alba seedlings was 100, 100, 200, and 400 mg·kg-1, respectively. Finally, the study revealed that broadleaf species require higher calcium concentrations than coniferous species.

Solute carrier (SLC) proteins transport a wide range of substrates across biological membranes and more than 400 proteins are considered as SLCs based on its sequence. Despite it has important potential applications in drug development, the SLC superfamily is still understudied. Drosophila blot, an orphan SLC protein, regulates F-actin organization in the syncytial blastoderm and the Malpighian tubules. However, the molecular mechanism was unknown. In this study, we found Blot was localized at the furrow canal, the front of the invaginating membrane during cellularization process. Blot is required for maintaining proper morphology of furrow canal and cellularization process. By affinity purification and mass spectrometry we identified RhoGEF ELMO/DOCK complex was required for Blot-mediated F-actin organization and cellularization. Further analysis revealed that ELMO localization depends on Blot. Taken together, we propose Blot plays a role in F-actin organization as an upstream factor of ELMO by recruiting ELMO to the target membrane compartments.

Published: May 2023

With the improvement in medical quality, cold mechanical rehabilitation equipment can no longer meet the psychological needs of the physically handicapped. Therefore, design for behaviour change should be viewed as a strategy for enabling lifestyle changes as soon as possible. Although how to use equipment to assist physically disabled people in hydrotherapy rehabilitation is the primary design goal, the psychological feelings of users are also one of the focuses of this study. Besides, coupled with the large-scale spread of the Coronavirus Disease (COVID-19) in the past two years. People's living habits are also forced to change, many activities that people are used to doing outdoors are being slowly completed at home. During the epidemic, it is very dangerous and inconvenient for users who need to go to institutional rehabilitation regularly. Hence, it is urgent to change past usage habits and places. In this study, a personal multi-functional hydrotherapy bucket is designed. In addition to not having to use a public spa with other people to reduce the risk of contracting the Coronavirus Disease, it can be easily placed at home by reducing its size. According to market research, it is known that the current domestic hydrotherapy buckets on the market usually only have a single function. The large medical hydrotherapy pools are not only rare in Taiwan, but this kind of equipment also takes up a lot of space. Various factors have resulted in a relatively low market share of hydrotherapy pools compared to other rehabilitation equipment. In order to take into account, the physical and psychological needs of the physically disabled, this research focus on the design of a multi-functional but small-sized hydrotherapy bucket. Taking the convenience of entering and leaving the bucket as the starting point to improve the shortcomings of the existing products, on the other hand, because most users are inconvenient to move, safety is also the focus of the design to reduce the occurrence of accidents and injuries. This study is based on the systematic design methodology of concurrent design to obtain product design results. Firstly, conduct market research and select products from different manufacturers for analysis and comparison. Through functional analysis and sorting out the problem points, the TRIZ theory and the morphological diagram method are used to find the solution to the problem. Finally, the best design scheme is obtained by the PUGH method. Besides, construct a 3D model to present the design concept that meets the design goals. The research results are hoped to be used as a reference for designing and developing related products, thereby increasing the home's multifunctional hydrotherapy buckets' market share.

The current methods for lightning risk warnings that are based on atmospheric electric field (AEF) data have a tendency to rely on single features, which results in low robustness and efficiency. Additionally, there is a lack of research on cancelling warning signals, contributing to the high false alarm rate (FAR) of these methods. To overcome these limitations, this study proposes a lightning risk warning method that incorporates enhanced empirical Wavelet transform-Adaptive Savitzky Gorey filter (EEWT-ASG) and one-dimensional morphology, using time-frequency domain features obtained through the Wavelet transform (WT). The proposed method achieved a probability of detection (POD) of 77.11%, miss alarm rate (MAR) of 22.89%, FAR of 40.19%, and critical success index (CSI) of 0.51, as evaluated on 83 lightning processes. This method can issue a warning signal up to 22 minutes in advance for lightning processes.

The methamphetamine epidemic continues to worsen each year and has contributed to more overdose deaths than opioids. Methamphetamine was listed in the top ten lethal drugs in 2021 in the United States. The drug has been shown to cause many health problems. One solution to this crisis is through vaccinations. Although still early in the development phase, vaccinations have been found to improve withdrawal symptoms and decrease drug seeking behavior with minimal health side effects compared to medications.
Social Interactions on Multi-Lane Motorways: Towards a Theory of Impacts
Authors: Schakel Wouter , Knoop Victor , Keyvan-Ekbatani Mehdi , van Lint Hans
Published: May 2023

Recent empirical work has revealed that drivers have different lane change strategies. These strategies help to understand driver heterogeneity and decision stochasticity, which are both often lacking in microscopic models. In this paper we generalize the lane change strategies in a theory for social interactions. The theory introduces a mechanism by which two new driver traits, ego-speed sensitivity and socio-speed sensitivity, endogenously influence other driver traits that govern lane change behaviour such as desired speed, desired headway and lane change desire. A key concept in this mechanism is that drivers are not just affected by what happens in front of them, but also by what they observe in their rear-view mirrors. The idea is that drivers reduce their headways to exert (social) pressure onto leading drivers (on the same or adjacent lanes), which may force them to increase speed, change lanes, or conversely, to refrain from changing lanes. We refer to this reduction of the headway as tailgating. Through an example implementation of the theory, we demonstrate that these social interactions may have a profound impact on several key (mesoscopic) traffic flow characteristics. Our results show that these new driver interactions influence the number of lane changes, platoon lengths, and headway variance. As such, the theory improves our description and understanding of traffic flow and consequently it paves the path for more realistic traffic models.

To date, genital sclerotic and atrophic lichen is a common pathology at the appointment of a urologist. The relevance of studying this disease is due to the variety of clinical manifestations, which makes it difficult to make a timely diagnosis. In addition, the lack of guidelines and clinical recommendations for the management of such patients, the lack of up-to-date information among practitioners about topical corticosteroids as first-line drugs in the treatment of genital lichen sclerosus lead to the fact that patients do not receive adequate therapy for a long time. Complications such as phimosis, synechia of the frenulum, meatal stenosis, urethral strictures develop, and the risks of malignancy increase. Given these circumstances, this lecture summarized key data on the clinical picture, diagnosis and treatment of dermatosis. The information from this work can be applied in the daily work of practicing physicians, which will both prevent the adverse effects of lichen and determine the tactics of managing a patient with existing complications.

Catatan editor kali ini mencoba untuk melihat perspektif umum dari peran kecerdasan buatan atau artificial intelligence (AI) dalam ilmu psikologi dan dampaknya terhadap kesehatan mental manusia. Penulis menunjukkan bahwa teknologi AI dapat memengaruhi berbagai aspek perilaku dan kesehatan mental manusia, seperti gangguan tidur, ketergantungan pada teknologi, dan masalah kesehatan mental lainnya. Selain itu, teknologi AI juga dapat memengaruhi pengambilan keputusan manusia dalam berbagai bidang, seperti pada perekrutan karyawan atau penegakan hukum.

Salah satu studi di jurnal Cyberpsychology, Behavior, and Social Networking menunjukkan bahwa ketergantungan pada internet dan teknologi dapat menyebabkan gangguan perilaku, seperti obsesi dengan internet, rasa cemas saat tidak menggunakan perangkat digital, dan kehilangan kontrol atas penggunaan teknologi. Studi yang ada menunjukkan bahwa semakin sering seseorang menggunakan teknologi, semakin besar kemungkinan mereka mengalami masalah kesehatan mental.  Oleh karena itu, psikologi harus memahami dampak dari perkembangan teknologi AI terhadap kesehatan mental dan perilaku manusia. Psikologi dapat memainkan peran penting dalam mengatasi tantangan yang dihadapi oleh teknologi AI, seperti mengembangkan strategi untuk mengurangi ketergantungan pada teknologi dan mendorong penggunaan teknologi AI yang bertanggung jawab. Artikel ini diharapkan dapat memberikan pemahaman yang lebih baik tentang peran AI dalam ilmu psikologi dan memotivasi para peneliti untuk melakukan penelitian lebih lanjut tentang dampak teknologi AI terhadap kesehatan mental manusia.
