ANALISIS KOMUNITAS ONLINE (PERMASALAHAN HUBUNGAN MENGANDALKAN KASIH DALAM KOMUNITAS MUSIK ROHANI ONLINE ‘EPIX’)
Authors: Ayomi Nesya Putri
Published: January 2022

Komunitas merupakan unit sosial yang tersusun dalam bentuk kelompok dengan individu-individu yang memiliki kepentingan bersama, baik bersifat fungsional maupun teritorial. Komunitas online menjadi alternatif bagi komunitas musik untuk bisa terus melaksanakan kegiatan tanpa menghilangkan eksistensinya di tengah situasi pandemi. Salah satunya Komunitas Epix, komunitas online musik rohani yang muncul di kala pandemi dimana seluruh kegiatannya dilaksanakan secara online dengan memanfaatkan teknologi. Namun, dalam dinamikanya Komunitas Epix mendapati permasalahan hubungan dalam dinamikanya yang mengandalkan ajaran “kasih”. Tujuan dari penelitian ini adalah untuk mengetahui permasalahan yang timbul dari hubungan yang mengandalkan ‘kasih’ dalam Komunitas Online Musik Rohani ‘Epix’. Penelitian ini menggunakan metode Participatory Action Research (PAR). Berdasarkan hasil penelitian, terlihat bahwa nilai kasih yang diterapkan oleh Komunitas Epix tersebut bagaikan pedang bermata dua bagi kegiatan dan perkembangan komunitas. Sebab secara tidak disadari oleh anggota komunitas, nilai kasih yang diterapkan menimbulkan permasalahan atau hambatan dalam berdinamika atau dalam mengembangkan komunitas itu sendiri. Bentuk permasalahan tersebut merupakan saling memaklumi dan saling memaafkan dalam adanya kelalaian tanggung jawab, kemauan untuk membackup anggota yang tidak 

melaksanakan tanggung jawabnya, tetapi tidak mencari akar dari permasalahan dan berusaha mencari solusi di luar “saling memaklumi dan memaafkan” tersebut supaya tidak terjadi di kemudian hari. Hal ini dapat memupuk sifat egosentris pada anggotanya dan menurunkan sense of belonging terhadap komunitas, sehingga berbahaya bagi keberlangsungan komunitas kedepannya.

Self-defense as an inherent right owned by a country is regulated in Article 51 of the UN Charter and due to the use of Space-Based Missile Interceptor (SBMI) weapons in space, the 1967 outer space treaty must also be guided. Because Article 4 of the 1967 Outer Space Treaty prohibits the use of weapons in space, the legality of using SBMI weapons is questionable. Therefore, this study was conducted to determine the legal provisions, forms of state accountability and the process of prosecuting compensation for countries using these weapons according to international law. The results of the study indicate that the use of SBMI weapons does not conflict with international law, because it is based on Article 103 of the UN Charter which states that if there are provisions in other legal rules that are contrary to the UN Charter, the UN Charter must be guided. So that self-defense actions based on Article 51 of the UN Charter do not violate the law. The party that must be absolutely responsible is the country that started the conflict, because it has violated the rules of international law in Article 2 paragraph (4) of the UN Charter and international humanitarian law. The compensation process is carried out according to the rules of the space liability convention 1972 and if in practice the party who is responsible does not show good faith in providing compensation, then it can be continued by referring to the dispute resolution process in the UN Charter.

NEW DESIGNS OF UNIVERSAL PLANTING MACHINES FOR PLANTING SEEDLINGS WITH OPEN AND CLOSED ROOT SYSTEMS
Authors: Drapalyuk Mikhail , Stasyuk Vladimir , Zelikov Vladimir
Published: January 2022

Currently, in the Russian Federation, a large number of areas require reforestation. Introduction of new technologies in artificial reforestation (planting seedlings with a closed root system) requires the use of new means of mechanization when planting seedlings. The assessment of the degree of similarity and difference of the selected structures was carried out on the basis of statistical analysis (hierarchical classification). The country's industry practically does not produce tree planting machines for planting seedlings with a closed root system. Imported specimens of forest planting machines are expensive, require aggregation with heavy equipment, which is practically absent in forestry. In addition, climatic conditions may also be a limitation in the use of imported equipment. In connection with the above, Voronezh State University of Forestry and Technologies has developed designs of universal planting machines with rotary and chain planting mechanisms. They enable planting of both standard seedling and seedlings with closed root system. The use of universal tree planting machines in forestry enables to keep one tree planting machine instead of two specialized ones. This will significantly save on maintenance and storage of mechanisms

Published: January 2022

The operating conditions of wheeled forwarders have been considered. The requirements for the efficiency of the braking system are described, as well as methods for testing the working and parking braking systems of wheeled forestry machines when operating on ups and downs of up to 50%. The most severe brake loading situations in terms of keeping the forwarder on a slope have been shown. A calculation scheme for determining the loads in the contact patch during the descent of a wheeled forwarder has been drawn up. The initial data necessary for calculating the braking system of the machine have been given. The results of calculations of reactions when the forwarder is located on a horizontal support surface and the calculation of reactions in the contact patch of the wheel during descent and ascent are given. The technical parameters of the braking system of the NAF TAP 7601 balancer axles used on the developed machine have been presented. The results of calculations of the braking properties of the forwarder in running order and at full weight on the descent (characterized by the parameters α = 40% and α = 50%, as well as on the ascent α = -50%) have been presented. The results of calculations of the required braking torque on the wheels of the machine, the maximum-realized braking torque for the adhesion of all wheels of the front and rear axles of the machine have been presented. The safety factor of braking mechanisms and the safety factor for adhesion have been given
STUDY OF A SET OF TECHNOLOGICAL OPERATIONS FOR THE PREPARATION OF CONIFEROUS SEED MATERIAL FOR REFORESTATION
Authors: Novikova Tatyana
Published: January 2022

Preliminary studies have shown the need to develop an integrated approach to the problem of reforestation, which would take into account current trends in the field of ecophysiology, technology and technology of forestry, as well as the efficiency of technological processes. At the first stage, a reforestation algorithm was developed to implement this approach. The algorithm consists of 31 enlarged technological operations and 268 implementations of the algorithm. The algorithm was decomposed for further detailed study of technological operations and the development of a mathematical model aimed at finding the optimal set of operations for reforestation. Six groups were identified, each of which should be considered separately. The work considers the 10th operator of the III-th and V-th groups. An algorithm for preparing seeds and an algorithm for separating seeds have been developed. The matrices for the implementation of the algorithms were constructed (a 13 × 16-dimensional matrix for the preparation of forest seeds and a 14×35-dimensional matrix for the separation of forest seeds, containing binary values). A visualized proximity matrix based on the squared Euclidean distance and the Ward method was used to study the operators of algorithms for similarity. As a result of data processing, the operators of the algorithm are determined, which are far enough from the center of the groups, which can be ignored in the future when developing an optimization mathematical model of the reforestation process

Published: January 2022

This work evaluates the tests of a 2 class tractor (integrated packaging LTZ -155) with front, rear, and combined aggregation, with the possibility of combining operations in the cultivation of row crops and forest plantations by using combined aggregates with forestry and agricultural vehicles with front and rear hinges. An assessment of the performance and efficiency of using such units with their vibration loading has been shown. During experimental studies of the tractor with different mounting methods (rear, front, both front and rear) of a cultivator weighing 2200 kg, horizontal and vertical components of traction resistance, as well as torques on the driving wheels of the tractor, were obtained by tensometric measurements. The work of the tractor took place at a specially prepared landfill for reforestation, to a depth of 4 and 8 cm, respectively, for the rear and front cultivators. The developed tensometric framework was used to analyze the resulting traction resistance. Field tests showed that the dynamics of the processes of power parameters for a unit with front and rear cultivators was significantly lower than with only front or rear cultivators. The absolute value exceeded 2 tons, i.e. traction class of the tractor. The applied spectral correlation analysis showed that these processes had low-frequency spectra (up to 1 Hz). They were “white” noise relative to each other. This, in mathematical modeling, simplifies the formation of the structures of the "impact" and "machine" subsystems

Published: January 2022

Comparative analysis of heavy metal accumulation in the needles of introduced species in the green zone of Nur-Sultan has been carried out. 10-year-old forest plantations created from introduced conifers of the genus Spruce (Picea), Fir (Abies) and Larch (Larix) have been investigated in the green zone of Nur-Sultan. Siberian spruce (Picea obovata Ledeb.) has the greatest ability to absorb heavy metals, then (in decreasing order): black spruce (Picea mariana Mill.), Engelmann spruce (Picea engelmannii Parry ex Engelm.), Siberian fir (Abies sibirica Ledeb.), Siberian larch (Larix sibirica Ledeb.), Colorado spruce (Picea pungens Engelm.). The needles of introduced species were found to exceed the MPCs for lead (Pb), cobalt (Co), and manganese (Mn). High concentration of manganese led to a decrease in the concentration of active iron (Fe), the manganese-iron ratio in trees of the Spruce genus was 1.6-2.9: 1 in all the studied conifers. The content of this element in Siberian larch was the highest (34.9 mg/kg) one, but iron was also present in a fairly large amount (19.7 mg/kg), so the manganese-iron ratio was 1.8:1. Gas resistance and a tendency to accumulate heavy metals in needles, decorativeness and high preservation have been shown by spruce Siberian, which can be recommended for planting in the green zone. Black spruce and Engelman spruce are also resistant to unfavorable environmental factors and decorative. The accumulation capacity and safety of Siberian larch, as well as Siberian fir, is very low, so these species should not be recommended for growing in the green zone of Nur-Sultan
VARIABILITY OF THE HARDNESS OF PINE WOOD DAMAGED BY STRONG GRASSROOTS AND RAMPANT RIDING FIRE
Authors: Snegireva Svetlana , Platonov Aleksey , Kiseleva Aleksandra , Kantieva Ekaterina
Published: January 2022

Fires cause huge damage to forests. The degree of damage to plantings depends on the type of fire, which is largely determined by climatic conditions, terrain, age of plantings, etc. The greatest damage to plantings is caused by a strong grassroots and rampant riding fire. The commodity value of such wood is minimal. Resin formation processes occur in wood damaged by fire. The degree of tarring of the wood depends on the viability of the cambium. The thin bark of young trees does not provide sufficient protection of cambium from heat exposure and trees die quickly. A thick layer of bark partially protects the cambium and the resin formation processes are activated in the wood, which can take a long period of time. The effect of high temperature, including its tarring, has a significant impact on the physical and mechanical properties of wood. Information about the quality of wood damaged by fire and their variability during long-term storage or during operation is of great practical importance. The aim of the study is to establish the static end hardness of pine wood damaged by a strong grassroots and rampant riding fire, after long-term storage in room conditions. It was found that during storage for 10 years, the static end hardness of tarred pine wood increased by 1.9-2.2 times, compared with the indicators at the time of cutting wood after a fire and exceeds the indicators of intact pine wood in trees with a trunk diameter of 22-26 cm by 42.5% and a diameter of 50-56 cm by 67.7%. The degree of tarring and the strength of wood are higher in trees with thicker bark

Optimized Mesh-free Analysis for the Singularity Subtraction Technique of Linear Elastic Fracture Mechanics
Authors: Oliveira Tiago , Portela Artur
Published: January 2022

In linear elastic fracture mechanics, the stress field is singular at the tip of a crack. Since the representation of this singularity in a numerical model raises considerable numerical difficulties, the paper uses a strategy that regularizes the elastic field, subtracting the singularity from the stress field, known as the singularity subtraction technique (SST). In this paper, the SST is implemented in a local mesh-free numerical model, coupled with modern optimization schemes, used for solving two-dimensional problems of the linear elastic fracture mechanics.
The mesh-free numerical model (ILMF) considers the approximation of the elastic field with moving least squares (MLS) and implements a reduced numerical integration. Since the ILMF model implements the singularity subtraction technique that performs a regularization of the stress field, the mesh-free analysis does not require a refined discretization to obtain accurate results and therefore, is a very efficient numerical analysis.
Mesh-free numerical methods control the accuracy and efficiency of the model through the size of compact supports, the size of integration domains and the distribution of nodes in the body, which are usually heuristically determined through an expensive and time consuming calibration effort. The leading innovation of this paper is the automatic definition of these parameters and the nodal distribution by means of a multi-objective optimization, based on genetic algorithms (GA), with reliable and efficient objective functions. The optimization scheme effectively automates the whole pre-processing phase of a numerical analysis with mesh-free methods.
Benchmark problems were analyzed to assess the accuracy and efficiency of the modeling strategy. The results presented in the paper are in perfect agreement with those of reference solutions and therefore, make reliable and robust this mesh-free numerical analysis, coupled with a multi-objective optimization,for linear elastic fracture mechanics problems.

La educación en materia de prevención de salud representa un reto en el que México, debido a su diversidad social, cultural, geográfica, económica y política; tiene una deuda histórica. Si bien es cierto que esta situación debe enfrentarse desde varios flancos: educación, economía, condiciones de trabajo, disponibilidad de los servicios y profesionales de salud – entre muchos otros – es indudable que la tecnología debe jugar un papel importante en todos. La experiencia de otros países de establecer expedientes clínicos electrónicos universales permite comprobar que conocer el estado de salud de su población permite a los gobiernos tomar decisiones que impacten de manera positiva en la población. El objetivo de este estudio es evaluar la reacción de los actores sociales (pacientes y médicos) a un sistema personal de salud. Con este fin se desarrolló un Sistema Personal de Salud basado en Android y compatible con el estándar HL7 v3 y se comparó contra su equivalente en papel. Se agrega el contexto de la pandemia causada por el Covid-19 debido a que durante la fase de pruebas el país comenzó con la primera ola de contagios; lo que afectó de cierta forma el número de pruebas, pero a la vez demostró la importancia de estas herramientas en situaciones críticas. Los resultados permiten hacer inferencias importantes sobre las características que debe tener este tipo de herramientas para funcionar en el mercado mexicano.

Published: January 2022

A variety of fiber-optic temperature sensors based on inline Mach–Zehnder interferometry (MZI) have been implemented for their ease of fabrication and cost efficiency, but it is difficult to control the length of the sensing area (i.e. the fiber section with sensitivity). Herein, we develop a new temperature sensor based on inline MZI by connecting two single-mode fibers (SMFs) with different mode-field diameters and by applying a load to one of the SMFs. The fiber section between the connector and the load operates as the sensing area, the length of which can be dynamically controlled by changing the load position.

Published: January 2022

Acute Appendicitis is a common surgical emergency and Open Appendicectomy is widely performed. This study aims to
analyze the difference of outcome in peritoneal closure versus Non closure in open appendicectomy. Adult patients (18-
65 years) admitted and operated for Acute appendicitis were studied prospectively from July 2019 to July 2020 at King George Hospital,
Visakhapatnam. The intra operative time, post-operative pain, wound infection and duration of hospital stay were analyzed. Between July 2019
and July 2020 there were 86 patients with diagnosis of Acute appendicitis to the emergency casualty of KGH, Visakhapatnam and underwent
Open appendicectomy. They were divided into two groups randomly, Group A: Open appendicectomy with peritoneal closure (39) and Group B:
Open appendicectomy with non-closure of peritoneum (47). There was found to be a reduction in the duration of surgery, less post operative pain
and shorter duration of hospital stay in patients who underwent non-closure of peritoneum compared to patients who underwent peritoneal
closure. There was no difference in incidence of post-operative wound infection when compared to closure of peritoneum. Non closure of
peritoneum is associated with shorter operative time, reduced requirement of post-operative analgesia and shorter duration of hospital stay and
hence can be safely recommended.

The purpose of this study was to outline the patterns, indications and short-term complications of major limb amputations attending King George Hospital, Tertiary Care Centre, Visakhapatnam. This was a retrospective study at the King George Hospital between June 2019 and May 2020. Data were collected using previous medical records of the patients. A total of 80 patients were entered into the study. Their ages ranged between 20–70years with an average age of 53.5 yrs. Males outnumbered females by a ratio of 4:1. The most common indication for major limb amputation was diabetic foot complications followed by vascular disease, trauma, gas gangrene I and high voltage electrical burns respectively. Lower limbs were involved in 77.5% of cases and upper limbs in 22.5% of cases giving a lower limb to upper limb ratio of 3.4:1. Below knee, amputation was the most common procedure performed in 46.25%. There was no bilateral limb amputation. All the aspects regarding the type of amputation, complication rates, etiologies, have been studied. In limb amputations, the indications are many and the pattern varies from place to place. Complications of diabetic foot ulcers, PAOD and trauma resulting from road trafc crashes were the most common indications for major limb amputation in our environment. The majority of these amputations are preventable by the provision of health education, early presentation and appropriate management of the common indications.
Male Role in Emergency Obstetric Care in Rural Niger Delta, Nigeria
Authors: Akpandara Tarilaifa
Published: January 2022

After more than two decades of continuous democratic rule and government policies geared towards improved emergency obstetric care (EmOC) access in Nigeria, maternal mortality remains a fundamental public health challenge. Although many studies have emphasized the significance of the male role in female reproductive health-seeking behavior in the country, there is insufficient empirical evidence on the male role in accessing EmOC in Nigeria’s Niger Delta region, the bastion of the nation’s petroleum industry. This study explored women’s perspectives, beliefs, and experiences concerning the role of their husbands on reproductive health by collecting quantitative and qualitative data in an economically disadvantaged community of Bayelsa State. A semi-structured questionnaire was administered to 616 women aged 15-49 years. Focus Group Discussions (16) were conducted among purposively selected male and female participants. Men play positive roles toward accessing EmOC by women in rural Bayelsa. At least eight out of ten women reported that their husbands were present during pregnancy or birth complications; five out of ten claimed they followed them to hospitals or clinics for treatment. Men also provided the finance for the specialized care during emergencies. This study provides empirical evidence of a positive male role in accessing EmOC in the study area. More deliberate promotion of male involvement in the reproductive health of their wives will contribute significantly to the reduction of maternal mortality in a patriarchal society such as Bayelsa.
Social Reintegration of Rehabilitated Drug Abusers: An Explorative Investigation of Views of Rehabilitees in Lagos, Nigeria
Authors: Adejoh Samuel Ojima
Published: January 2022

Objective: This study examined the influence of family structure, employment opportunities, marital status and stigmatization on reintegration of rehabilitated drug abusers in Lagos, Nigeria.

Method: This study used the qualitative research design to collect data from 50 respondents. The study was conducted in a Neuro-Psychiatric Hospital using the outpatient clinic. Data were analysed adopting the phenomenological approach of analysis. Nvivo 12 plus was used to analyse the data.

Findings: Immediate family members were supportive of drug abusers’ reintegration with those from monogamous family receiving more support than those from the polygamous family structure. Being married is an important factor in rehabilitation and reintegration as expressed by the respondents. Being employed either in private or private sector assisted them in keeping their eyes off drugs. Stigmatization was experienced at community level, workplaces and even among friends and peer.

Conclusion: Efforts should be put in place to educate members of the public on the need to support drug abusers undergoing rehabilitation and reintegration for total reintegration into the society. This involves avoiding any of stigmatization towards rehabilitated drug abusers.
‘…her aim was to ruin my reputation’: Cyberstalking Victimization Experiences among University Students in Nigeria
Authors: Tade Oludayo , Popoola Oluronke Dorcas
Published: January 2022

While global knowledge about cyberstalking is growing, intellectual engagement of the phenomenon in Nigeria is still at infancy and focused mainly on awareness. Scanty attention has however been paid to the nature of victimization experiences and its effects on victims. Against this background, this study investigated the nature and effects of cyberstalking among victims at the University of Ibadan. Using purposive and snowball sampling techniques, 30 victims of cyber stalking were subjected to indepth interview. Results indicated that their active online activities and the anonymity guaranteed in cyberspace contributed to their victimization. While one of the social and psychological effects of cyberstalking is social estrangement of victims, most victims failed to report to the Police owing to fear of repeat victimization and lack of trust in the policing institution. Instead, they accessed informal coping mechanisms from friends and family.
Appraisal of Socio-Economic and Political Implications of COVID-19 Pandemic on Residents of Enugu State, Nigeria
Authors: Ogbuke Martha Uchenna
Published: January 2022

COVID-19 pandemic determines public health, presenting the biggest threat since the Second World War. All continents, except for Antarctica, are active in battling the pandemic. As other socio-economic and political problems are arising from this crisis, the pandemic cannot only be attributed to health issues. Every nation affected by this pandemic may witness a destructive or ravaging social, economic, political and psychological backlash that may leave long lasting scars. The World Bank has projected a decline in remittances of $110 billion and 800 million people will not be able to meet basic needs this year, with the International Labour Organization (ILO) forecasting that over 195 million people will lose their jobs. In managing this pandemic, there is a need for strategic planning by a government organization through the development of long-lasting policies that will help minimize the impact on individuals and nations. Previous experiences of epidemics such as Ebola, HIV, SARs, TB and Malaria will therefore be valuable in the development of policies that can help to mitigate the socio-economic and political impact. The solution may lie in contacting the most vulnerable through crowd sourcing to provide them with food, in particular life necessities. Expanded social security may also be an important step in that direction for the disadvantaged and the disabled.

Published: January 2022

The outbreak of COVID-19 pandemic spiraled serious economic crisis to the households. While studies have largely focused on the formal mechanisms to cushion its effects on households’ livelihood, study on the informal mechanisms is still scanty. This study, therefore, examined the roles of Baraza as a Multipurpose Cooperative Society (MCS) during COVID-19 lockdown in Yenagoa City. The theory of planned behaviour was adopted, while a cross-sectional survey design was employed. A respondent-driven sampling was utilized to sample 380 respondents through Baraza MCS using a structured-questionnaire. Descriptive statistics and multiple linear regression were used as analytical strategy at p<0.05. Findings revealed that the majority were males, employed and had B.Sc/BA as educational qualification. It was further indicated that the majority had long-term plan (62%) in the scheme, as it served as an alternative source of income (54.7%), income diversification (55%), as well as a cushioning mechanism for COVID-19 pandemic (34.3%) among others. The predictor variables jointly predicted the level of satisfaction derived from the scheme during the pandemic at (R=0.33, R2=0.11; AdjR2=0.10, F(5,369)=9.23), while the average investment (β=.375, t=2.740), contributory platform (β=-.550, t=-2.360) and number of packages (β=.558, t=3.298) of respondents significantly predicted the level of satisfaction derived from the scheme. In spite of these, the fear of political interference (39.7%), interest reduction (38.4%), collapse (33.7%), etc. were the associated challenges with the scheme. It is imperative that the scheme are thoroughly supported and regulated by the concerned agencies in order to enhance its roles as alternative source of livelihood sustainability particularly during economic crisis.

Cucurbits are among the most cultivated crops, and the most economically important species are melon (Cucumis melo L.), cucumber (Cucumis sativus L.), watermelon (Citrullus lanatus Thumb.), squash (Cucurbita pepo L.), and pumpkin (Cucurbita spp.). These crops have become important income sources providing export and local consumption commodities in many Mediterranean countries. Increased area of cucurbits has led to the emergence of several viral diseases, which can have impacts on crop production and threaten agricultural sustainability. An overview of the most damaging cucurbit viruses in the Mediterranean area is provided to improve understanding of the diseases they cause and to emphasize effective disease management strategies. An updating of the geographical distribution of these viruses, the symptoms they cause and their means of transmission is also provided. Disease management methods and measures by farmers and phytosanitary authorities to address the virus outbreaks are outlined, including diagnostics, use of tolerant cultivars, and chemical and biological vector control. Mediterranean region farmers have learned many lessons from the damaging pandemics caused by cucurbit viruses, through the extensive published research, and this review provides a basis for managing future outbreaks of newly emerging virus infections.
