Introduction. A healthy lifestyle is one of the most eff ective methods of preserving health and preventing non-infectious diseases. The mechanisms and factors that infl uence the formation of motivation for health and a healthy lifestyle in employees engaged in harmful working conditions have not been suffi ciently studied. The study of these mechanisms will allow us to more eff ectively shape health-saving behavior.The aim of the study is to study negative aff ectivity, social suppression and anxiety in the formation of motivation to maintain health and a healthy lifestyle in coal industry workers.Materials and methods. A survey was conducted of 75 employees of mines and sections in the South of Kuzbass with an established diagnosis of occupational diseases, as well as 54 people who do not work in harmful working conditions (engineering and technical workers). Surveys were conducted using the method “Index of motivation to health and a healthy lifestyle”, the presence of personality type D was conducted using the DS14 questionnaire, the level of personal and situational anxiety was assessed using the Spielberger — Hanin questionnaire.Results. Th e level of motivation for health and a healthy lifestyle among patients with occupational diseases is signifi cantly lower than the level of motivation for the health of engineering and technical workers. Th e infl uence of negative reaction and social suppression on the level of motivation for health and a healthy lifestyle was not found. Th e level of situational anxiety also has no eff ect on health motivation. A higher level of personal anxiety among people with a high level of motivation for a healthy lifestyle was determined.Conclusions. Personal anxiety aff ects the level of motivation for health and a healthy lifestyle in people with occupational diseases.
Issues of non-standard employment: social and hygienic aspects
Authors: Druzhilov S. A. 
Published: July 2020

Drastic transformations of the social and labor sphere have led to the emergence of new health risks and sanitary and hygienic problems associated with unreliability of employment. A new socio-economic and psychological phenomenon “precarity” has emerged, which has aff ected the employment conditions of employees, so the description of the phenomenon “precarity” needs to be clarifi ed.The forms of labor employment that diff er from the typical model and worsen the employee’s situation are considered. The criteria based on which non-standard employment is considered unstable are given.Generalized types of unstable employment are identifi ed, the specifi city of which is determined by a combination of two factors: working time and the term of the contract. Unstable working conditions are possible not only in informal employment, but also in legal labor relations. Unreliability and instability of labor has an objective character and is a natural manifestation of the emerging economic and social order. The phenomenon of “precarity of employment” appears as a new determinant of the health of employees. The main feature when referring employment and labor relations to the phenomenon of “precarity” is their unreliability.Specifies the terms used: “precariat”; “precarious work”; precompact; the precariat. An essential characteristic of precarious employment is the violation of social and labor rights and lack of job security. A significant indicator of precarity is underemployment. Precarity induces the potential danger of dismissal of the employee and the resulting stress, psychosomatic disorders and pathological processes in the psyche.Precarious employment and related labor relations have become widespread. Many employees are deprived of social guarantees, including those related to labor safety, payment for holidays and temporary disability, and provision of preventive measures. Th is leads to a violation of the state of well-being, as well as the deterioration of individual and public health.

Published: July 2020

Introduction.Adverse working conditions can contribute to the development of not only occupational pathology, but also diseases with complex multifactorial etiology, such as hypertension, coronary heart disease, disorders of the musculoskeletal system, chronic non-specifi c respiratory diseases, as well as the formation of combined pathology, which worsens the course of these diseases and leads to the development of complications.The aim of the studyis to study the manifestations of somatic pathology in coal industry workers with vibration disease.Materials and methods. We examined 144 coal mine workers with vibration disease caused by local vibration, and 161 control group miners who have been working in contact with local vibration for a long time (15 years or more) and do not have professional pathology.It was found that employees of coal mines with vibration disease more often (70,8%) than workers of the control group (27,3%) (p<0,001), there is a pathology of internal organs: diseases of the cardiovascular system (mainly arterial hypertension), diseases of the digestive system (functional disorders of the biliary tract and non-alcoholic fatt y liver disease), kidney diseases (mainly chronic pyelonephritis), as well as a combination of these diseases. With a more severe course of vibration disease (II degree), pathology of internal organs is more common (81.2%) than in patients with vibration disease of I degree (46.5%) (p<0.001).Conclusions. In miners with vibration disease, more oft en than in the control group, there is a pathology of internal organs: the cardiovascular system, digestive organs, kidneys, as well as a combination of several somatic diseases. In individuals with grade II vibration disease, internal organ pathology is more common than in patients with grade I vibration disease. Th e results obtained should be considered when developing treatment and rehabilitation measures for medical examinations and conducting preventive medical examinations of coal industry workers.

Th e results of using natural radon waters in the form of General or four-chamber baths and ozonopuncture in patients with occupational diseases of the joints and spine at the rehabilitation stage are presented. Studies have shown that the course use of radon therapy in combination with ozone therapy has a pronounced analgesic eff ect, anti-infl ammatory eff ect, stimulates the general sedative eff ect on the central nervous system, helps to restore the volume of movements in the aff ected joints, prevents the weighting of the joint process and the development of dystrophic changes in the musculoskeletal system.The aim of the study is to study the eff ect of natural radon waters combined with ozone therapy on the dynamics of functional indicators based on motor activity data in patients with occupational diseases of the joints.Patients with occupational diseases of the joints in rehabilitation were prescribed general radon or four-chamber baths in combination with ozone therapy (the main group). A control group of patients received radon baths by a similar method without introducing ozone. Before and aft er treatment, studies of functional activity in the aff ected joints were conducted: the volume of movements, the functional Leken index, which takes into account the severity of pain at rest and under motor load, pain assessment on a visual analog scale, echography of the aff ected joints, adaptive response according to L.Kh. Garkavi. Th e use of general or four-chamber radon baths in combination with ozone therapy in the main group allowed to quickly and eff ectively normalize the functional activity of joints, relieve pain, increase the body’s adaptive reserves to external stress factors, normalize sleep and restore working capacity. In the control group, changes in indicators did not have a signifi cant degree of signifi cance.The use of General or four-chamber radon baths in combination with ozone therapy at the rehabilitation stage in patients with occupational diseases of the joints causes an improvement in the functional activity of the musculoskeletal system, accelerates the disappearance of pain, relieves infl ammation, returns performance, normalizes the body’s adaptation to external infl uences.

The results of determining adaptive responses to treatment of patients with industrial injuries in the early stages of rehabilitation are presented. Studies have shown that the preliminary determination of reactions by L.Kh. Garkavi allows you to individually plan the duration of stay, the nature of treatment procedures with their sequence for each patient.The aim of the study is to study the adaptation indicators according to L.Kh. Garkavi in patients with occupational injuries before treatment, during rehabilitation and aft er its completion.Patients with industrial injuries, aimed at early rehabilitation, were determined by L.Kh. Garkavi adaptation reaction using the blood formula with the ratio of white blood cells, eosinophils, rod-shaped neutrophils, segmentonuclear neutrophils, lymphocytes, monocytes three times — before treatment, fi ve days aft er the end of the program. Th e resulting adaptation system data was evaluated as “training”, “quiet activation”, “increased activation”, or “stress”.The application of the scheme for diff erent periods of treatment according to the response of individually adapting the patient to begin rehabilitation contributed to the full year program: disappeared pain syndrome, restored the functional ability of the respective injured body, help prevent development of disability, decreased period of disability.The highly informative adaptation response, determined by the blood formula, answers the question about the reserve capabilities of this patient, which ultimately provides a positive result in the form of recovery of working capacity in the case of a fl exible rehabilitation scheme.

Published: July 2020

This paper touches on the important role of Islam in Malay literature and culture literacy, in the region. Malay literary and cultural treasures that were originally oral traditions have changed after the local community has embraced the teachings of Islam that bring along the Arabic scripture or Arabic writing system. This system of Arabic writing has greatly influenced Malay literature and culture. This paper therefore explores academically the role, contribution and discussion regarding the future of Arabic Scripture in the region. It would not be too much to say that it was the Arabic writing system that made the Malay community illiterate. This paper is expected to benefit not only to those who study literature and linguistic but for those with a background in Islamic studies too to study the regional literature and culture, especially those related to Malay studies.

Learning and Learning-to-Learn by Doing: An Experiential Learning Approach for Integrating Human Factors into Maritime Design Education
Authors: Abeysiriwardhane Apsara 
Published: July 2020

There is a growing awareness in the marine industry that human factors need to be considered in ship design if seafarers are to operate ships and systems safely and effectively. However, according to literature, the ship design practice today does not show explicit consideration of the end-users. This is mostly due to the ship designers’ lack of awareness and understanding about Maritime Human Factors (HF), Human Centred Design (HCD), and the operational issues that ships’ crew are facing during their sea time. This lack of knowledge can be traced back to the current educational system, which does not provide knowledge on HF, HCD approach, and maritime HF issues.

The authors conducted this study aiming to integrate HF and HCD knowledge into maritime design students’ educational platform and to motivate them to utilise this knowledge in their designs. Naval architecture students at the Australian Maritime College (AMC) were the participants of this study. Firstly, a classroom survey was conducted to determine the students current level of awareness and understanding of maritime HF and HCD. Then, an onboard survey was conducted after five HF-related activities during a seven-day voyage onboard MV Bluefin, which is the research vessel of AMC. The onboard activities provided the students with an opportunity for experiencing experiential learning including all its key elements based on Kolb’s experiential learning model.

The findings demonstrate how students’ onboard experiences influence their learning process by doing, discovering, reflecting, and applying. Students’ understanding of HF issues and the importance of the HCD approach was influenced during the onboard activities. They learned HF theoretical knowledge as an essential addition to their undergraduate curriculum. The results further highlight the experiential learning as a “paradigm of noteworthy learning” that supports multiple learning objectives for learners, including shaping their knowledge through experience.

Published: July 2020

La inamovilidad ciudadana determinada por la pandemia de COVID-19 generó una serie de impactos sobre el ambiente. Con el objetivo de evaluar la naturaleza de dichos impactos, se aplicó una técnica matricial (RIAM) que luego fue contrastada con información satelital de calidad de aire (CO y NO2), vigor vegetal en agroecosistemas (NDVI) y productividad primaria marina (OC3). Todos los impactos evaluados mediante el análisis matricial fueron calificados como positivos, aunque de corta duración y reversibles. En base a la información satelital, se observó una reducción equivalente al 16 % en la concentración de CO y al 4 % en NO2, mientras que el estado de la vegetación agrícola o la concentración de algas en el litoral no presentaron cambios. Los resultados indicaron que los impactos del confinamiento fueron positivos, pero de corta duración y restringidos a variables asociadas a actividades urbanas e industriales.

Published: July 2020

El boro (B) es un nutriente esencial para un adecuado desarrollo de las plantas. En regiones áridas o semiáridas es frecuente encontrar suelos con elevado contenido de B. Este exceso de B desencadena problemas importantes de toxicidad en las plantas, que conducen a una reducción de su crecimiento y a una disminución de la fotosíntesis, entre otros efectos. El maíz es uno de los cultivos de mayor importancia en Perú. Muchas de las tierras de cultivo del sur del Perú presentan contenidos elevados de B. La selección de razas que sean tolerantes a estas condiciones es fundamental para obtener mejores rendimientos en las cosechas. El objetivo de este trabajo fue caracterizar la tolerancia al exceso de B de las razas de maíz Pachía, Lipe-Coruca y Sama, originarias de la región de Tacna (Perú). Para ello, se cultivaron estas razas de maíz en macetas con tierras con alto contenido de B (214 ppm), y fueron regadas con aguas del río Sama cuya concentración de B fue de 14.63 mgL-1. Las razas Sama y Lipe-Coruca mostraron las mayores alturas con respecto al vástago. Además, la raza Sama presentó los más bajos contenidos foliares de B soluble e insoluble, y los mayores contenidos de clorofilas y carotenoides. En resumen, estos resultados sugieren que Sama es la raza más tolerante al exceso de B. Así, los menores contenidos de B y el mayor contenido de estos pigmentos de Sama permitirían una mejor adaptación al estrés generado por la acumulación de B en las tierras de cultivo.

El servicio del sistema de recolección de los residuos sólidos domésticos de la ciudad de Juliaca-Perú requiere de un mejoramiento y planificación más eficientes que permitan superar la excesiva generación y acumulación de los residuos sólidos que se encuentran en basureros, botaderos y a la intemperie. Debido a que la inadecuada selección de residuos orgánicos e inorgánicos y su disposición final generan descomposición que causa malos olores y lixiviados, propiciando la proliferación de insectos y roedores, vectores de microorganismos patógenos de humanos y animales, causando así un impacto negativo en el medio ambiente. El objetivo de esta investigación fue estimar el valor económico que la población está dispuesta a pagar para mejorar el sistema de recojo de residuos sólidos domésticos. Se aplicó el método de valoración contingente y el modelo econométrico binomial Probit. Se realizaron encuestas a 382 hogares. Se concluye que el 51.75 % de los encuestados están dispuestos a pagar por un sistema de recojo de residuos sólidos domésticos mejorado, con un costo promedio de S/ 5.36 mensuales; mientras que, el 41.10 % de los encuestados no estaría dispuesto a pagar. Asimismo, los factores que influyen en dicha decisión fueron el nivel educativo, la ética ambiental y la conciencia ambiental de la población de Juliaca.
