Authors: Rusdiyanto Johny
Published: February 2023

People’s lives have undergone a radical transformation as a result of the Industrial Revolution 4.0, and this concept is known as Society 5.0. The concept refers to a revolution in society that incorporates human and humanities aspects into its use of technology. Digitalization in some sectors has begun, utilizing big data, robotics, artificial intelligence, automation and machine learning, among other technologies. Toxic working conditions are those in which people are treated cruelly and violently, and this puts their health and safety at risk. Toxic work environments are more likely to develop in organizations that rely on technology more heavily. Small and medium-sized businesses (SMEs) are increasingly relying on work engagement, that also defines the level of commitment shown by employees to their work and organization. Toxic work environments (TWEs) have been shown to have an impact on employee engagement (EE). Data were collected from 301 employees of a socioeconomic firm in Surabaya, Indonesia, using a quantitative research approach. We used structural equation modeling with partial least squares to approximate the possible relationships in the research model.

Published: February 2023

The Shwebontha prospect area is situated in the Central Volcanic Belt, central Myanmar, where the well-known Sagaing Fault serves as its eastern boundary. This study aims to document key the mineralogy, host rock geochemistry and ore mineralizing fluids. The mineralization, hosted by Upper Oligocene to Middle Miocene rhyolites, displays a strong lithological control. Mineralization is characterized by gold-bearing silicified massive ore and chalcedonic quartz veins in which sulfides are clustered and disseminated not only in quartz gangue but also in rhyolite host rocks. The significant ore minerals in the mineralized veins include pyrite, sphalerite, galena, chalcopyrite, and gold. Common hydrothermal alterations such as silicic, argillic and propylitic alteration types are recognized. According to the fluid inclusion data and interpretation, ore mineralizing fluids in the research area are characterized by formation temperatures of 260-280 °C and salinity of 0.35-2.41 % wt. NaCl eq. respectively. Mixing of hydrothermal fluids was generally considered to be an effective mechanism for ore transport and deposition.
The Effect of Jet Grouting on Enhancing the Lateral Behavior of Piled Raft Foundation in Soft Clay (Numerical Investigation)
Authors: Elsawwaf Mostafa , Azzam Wasiem , Elghrouby Nahla
Published: February 2023

Soft clay soils cannot usually support large lateral loads, so clay soils must be improved to increase lateral resistance. The jet grouting method is one of the methods used to improve weak soils. In this paper, a series of 3D finite element studies were conducted using Plaxis 3D software to investigate the lateral behavior of piled rafts in improved soft clay utilizing the jet grouting method. Parametric models were analyzed to explore the influence of the width, depth, and location of the grouted clay on the lateral resistance. Additionally, the effect of vertical loads on the lateral behavior of piled rafts in grouted clay was also investigated. The numerical results indicate that the lateral resistance increases by increasing the dimensions of the jet grouting beneath and around the piled raft. Typical increases in lateral resistance are 11.2%, 65%, 177%, and 35% for applying jet grouting beside the raft, below the raft, below and around the raft, and grouted strips parallel to lateral loads, respectively. It was also found that increasing the depth of grouted clay enhances lateral resistance up to a certain depth, about 6 to 10 times the pile diameter (6 to 10D). In contrast, the improvement ratio is limited beyond 10D. Furthermore, the results demonstrate that the presence of vertical loads has a significant impact on sideward resistance.

Published: February 2023

Las zoonosis, como la rabia, el paludismo o el dengue, han afectado a los humanos desde nuestro origen. Ante la COVID-19, nuestro objetivo es destacar que los murciélagos no son los culpables de la pandemia; por el contrario, son muchos los servicios que proporcionan al ser humano en la salud, la agricultura, la alimentación y la economía. No se ha encontrado el SARS-CoV-2 en ningún murciélago: el contagio de la COVID-19 es entre humanos. El 70% de las enfermedades zoonóticas, como el SARS o el MERS, proviene de animales silvestres comercializados ilegalmente, por lo que es necesario eliminar la venta ilegal en mercados insalubres que representan un foco de contagios y proliferación de enfermedades infecciosas emergentes. El exterminio de murciélagos es perjudicial, no sólo para los propios murciélagos y el ecosistema, sino para nuestra salud, economía y bienestar.

Published: February 2023

Se exponen las ideas fundamentales del análisis de perturbaciones a multiescalas, también llamado método quasi-estacionario para soluciones tipo solitón. En esta aproximación las ecuaciones diferenciales no lineales perturbadas son linealizadas expandiendo las soluciones alrededor de las soluciones sin perturbar. En consecuencia, se calculan las auto-funciones del operador linealizado para poder obtener las perturbaciones de la solución solitónica. Además, se estudia la evolución de estructuras no lineales contenidas en la ecuación no lineal de Schrödinger y en la ecuación cúbica-quinta no lineal de Schrödinger con amortiguamiento.

Is There a Demand for Autocracy in Belarusian Society?
Authors: Rudkouski Piotr
Published: February 2023

2020 saw an unprecedented pro-democracy mobilization in Belarus. Indeed, protest actions against the grossly falsified presidential election and the authoritarian rule of Aliaksandr Lukashenka were impressive in many respects: number of participants, durability, frequency, and diversity. However, that year was also remarkable for mobilization of supporters of Lukashenka’s authoritarian rule: car rallies, pickets, and small-group marches in support of the incumbent lasted for months. Though far from being ubiquitous, a demand for autocracy does exist in Belarusian society. It can be explained by four factors: a tendency towards an economic trade-off, axiological Euroscepticism, the activity of pro-autocracy intellectuals, and the global decline in democracy.
