Published: May 2024

This study investigated factors contributing to poverty among artisanal fisherfolk in Ahoada Local Government Area of Rivers State, Nigeria. By exploring the livelihoods of artisanal fisherfolk, this paper analyzed different aspects of poverty and identify factors that contribute to poverty in these communities. This descriptive study was guided by two research objectives and questions. The population of study consists of 520 members of 3 fisherfolks cooperative society in Rivers State, out of which 240 members was randomly sampled. The research instrument used for the study was a structured 24 item questionnaire designed on a modified 4-poin Liker scale format. The findings of the study reveal that lack of access to loan facilities, reduction in catch and socio-economic factors contributed to poverty among fisherfolk in Rivers State. This study came to the conclusion that poverty is pervasive in coastal communities in Rivers State because the majority of fishermen who live and work there have daily challenges that exacerbate rather than reduce their economic condition. Based on this the paper recommended that in order to give fishermen access to loans and free themselves from the shackles of payday lenders, the government of Rivers State urgently needs to expand the establishment of microfinance banks to coastal communities. Additionally, fishermen need to be properly educated on the importance of maintaining clean waterways and the proper application of government regulations governing effluent discharge on water bodies.

Authors: Ruvy M Tuble , Elizabeth A Magno
Published: May 2024

Crop insurance is a crucial shield for farmers facing the challenges of climate change, including natural disasters, pests, and diseases. This descriptive-relational study using a researcher-made questionnaire examines the determinants of crop insurance adoption among 180 farmers in Negros Occidental's fourth district. The statistical tools are frequency, percentages, means, standard deviations, ranks, and linear regression. Findings reveal that coverage amount, covered risks, indemnity settlement, and adjustment significantly impact farmers' decisions to adopt crop insurance. Farmers highly value crop insurance for its potential coverage against pests and diseases. Correspondingly, loan requirements and farm eligibility moderately affect utilization, with debt levels emerging as a significant predictor. Optimizing crop insurance as a protection tool can raise farmer awareness and bolster agricultural sustainability and income stability. Recommendations include updating insurance components, expanding local government adoption, enhancing service delivery, and providing ongoing farmer education.

Authors: M Bajracharya , D Bajracharya
Published: May 2024

Background: COPD is a disease caused by chronic bronchitis, emphysema, or combination of both conditions. As per the Global Burden of Disease 2017 prediction, COPD is the second leading cause of death in Nepal, the fourth leading cause of premature death and the third cause for disability-adjusted life years (DALYs) in Nepal. The prevalence of COPD in Nepal was 11.7%. If current situation prevails, the burden of COPD might increase continuously in the nation. Hence, the findings from this study might provide baseline information to medical and paramedical students and other researchers to conduct further study in similar area. Objectives: The study was done to assess the prescription pattern for management of COPD in multispecialty hospital of Nepal. Method: A retrospective study was conducted at 100 bedded multispecialty hospital located at Lalitpur, Nepal. A total of 200 inpatient records, from Baishak 2075 to Chaitra 2078 were reviewed and data was collected as per the objectives and analysed by using SPSS version 16 and MS Excel 2013. Result: Out of 200 COPD patients studied, female patients (58%) were higher than male patients and maximum patients (42.5%) were from the age group 70-79. The most common symptom was shortness of breath (77.5%) followed by cough (50%) and fever (33.5%) Hypertension (38.5%) was the most frequent co morbidity seen among COPD patients followed by corpulmonale (20%) and diabetes mellitus type II (19%). Doxophylline was the most prescribed methylxanthines during hospitalization (47.5%) and discharge (51%) as well. Among inhalers, Tiotropium bromide and combination of Salbutamol and Fluticasone (52.5%) was prescribed most to the hospitalised patients. Hydrocortisone (68.5%) was the most prescribed corticosteroids during hospitalization where as Prednisolone (49.5%) was the most prescribed corticosteroids during discharge. 85.5% of patients were prescribed Ipratropium bromide for nebulisation in hospitalised patients. Pantoprazole (55.5%) was the most prescribed proton pump inhibitors followed by Rabeprazole (34%). Maximum patients (103) preferred Rotacap than metered dose inhaler (MDI) and dry powder inhaler (DPI). Azithromycin (52.5%) was most frequently prescribed antibiotics during hospitalization followed by ceftriaxone (85%), whereas among discharge patients, Cefpodoxime (35%) was most frequently prescribed antibiotics followed by Azithromycin (32%). The drugs prescribed with generic name were 31.31% and from essential drug list (EDL) was 37.72 %. Conclusion: The prescription pattern of COPD was studied and found that Doxophylline, Tiotropium bromide, Hydrocortisone and Azithromycin were most prescribed methylxanthnes, antimuscarinic agents, corticosteroids and antibiotics respectively. The findings from the study showed that prescribing drugs with generic name and from EDL was low so prioritization on prescribing drugs by generic name and EDL needs to be encouraged.

Prediction of secondary Structure of Proteins using Signal Processing Methods
Authors: Meher J K
Published: May 2024

The prediction of protein folding is important because the structure of a protein is related to its function. The study of protein structure therefore produces valuable practical benefits for medicine, agriculture and industry. The understanding of enzyme function allows the design of drugs which inhibit specific enzyme targets for therapeutic purposes. Structural information can provide insight into protein function, and therefore, high- accuracy prediction of protein structure from its sequence is highly desirable. Considerable research effort has been devoted to predicting the secondary structure of proteins from their amino acid sequences. Present methods of prediction based on the statistical methods and machine learning methods typically have 76% approximate level of accuracy on an average. Thus, there is a considerable room for improvement. Digital Signal Processing (DSP) is an Engineering discipline concerning the creation, manipulation and analysis of digital signals. New approach for the secondary structure prediction based on the DSP techniques can take major role for fast and accurate result. Unknown secondary structure of a targetprotein can be predicted by using the appropriate digital signal processing tools for a baseprotein of a significant amino acid sequence-similarity and whose secondary structure is known. In this study we present an extensive review of existing methods of secondary structure prediction of proteins

The Influence of SILAR cycle on the optical, morphological as well as compositional properties of Iron Copper Sulphide (FeCuS) thin film was reported. Utilizing the straightforward and reasonably priced SILAR technique, the deposition was carried out by the use of soda lime glass (SLG) substrates. With a concentration of 1.0M for Iron (Fe) ions, the deposition process was repeated 50, 60, and 70 times, with an 80-seconds dip time per cycle. Morphological characterization of the thin film was analyzed with Scanning Electron Microscopy (SEM) instrument. The compositional properties were analyzed with Energy Dispersive X-Ray machine. A UV-VIS Spectrophotometer was utilized to examine the thin film's optical characteristics. The presence of deposited thin film samples is confirmed by the SEM results, which display higher peaks for the elements Fe, Cu, and S. The results of the EDX analysis demonstrated that an increase in concentration enhances the homogeneity and adhesion of the deposited films in addition to their crystallinity. It was discovered that the thin film's energy band gap for each SILAR cycle was 0.9 eV, 1.3 eV, and 2.99 eV respectively.

PERSPECTIVES IN INNOVATION MANAGEMENT
Authors: Singh Ms. Yuvika
Published: May 2024

Interest in the concept of innovation has increased during recent years. Innovation management includes a set of tools that allow managers and engineers to cooperate with a common understanding of goals and processes. The focus of innovation management is to allow the organization to respond to an external or internal opportunity, and use its creative efforts to introduce new ideas, processes or products. The main innovation management dimensions are process, organization structures, strategies and people. Innovation is not just a fantasy it’s the concept of either innovate or die. Its main definition is to recognize the main problem, to solve the problem, to find the best solutions. To invest in innovation and just hope for the success is just the old concept, now the new concept is to invest in innovation and expect fully for the success. Optimum profitability can be obtained by having a balance between innovation pressure and ability to innovate. Innovation processes can either be pushed or pulled through development. A pushed process is based on existing or newly invented technology, that the organization has access to, and tries to find profitable applications to use this technology. A pulled process tries to find areas where customer’s needs are not met, and then focus development efforts to find solutions to those needs. Common tools include brainstorming, virtual prototyping, product lifecycle management, idea management, TRIZ, stage-gate process, project management, product line planning and portfolio management.

Authors: Semin Aleksei
Published: May 2024

The article provides a comparative analysis of the legal regulation of the right of civil servants to perform other paid work in the CIS member states. The general grounds for restricting the right to work of civil servants in the Russian Federation were researched, differentiation of approaches to restricting the right to perform other paid work by state civil servants, military personnel and persons undergoing other types of public service was exercised, and a number of gaps in the current regulation were also identified. The experience of the Republic of Azerbaijan, the Kyrgyz Republic, the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Republic of Moldova, the Republic of Tajikistan, the Republic of Uzbekistan and Turkmenistan was studied. Within the framework of the work, both trends common to all the states under consideration were highlighted – for example, the restriction of the right to perform other paid work for all civil servants, the existence of exceptions and conditions for the exercise of this right, and unique approaches that can be borrowed for the further development of legislation on the civil service of the Russian Federation. The article is characterized by a comprehensive and systematic study of the experience of regulation of the issue of performing other paid work by civil servants of the CIS member states, and its scientific novelty consists in identifying 2 basic models of restricting the right of civil servants to work (part-time) and classifying the approaches adopted in the states under consideration in accordance with the proposed models.
Battlefield informatization: some possibilities and possible problems
Authors: Tikhanychev Oleg Vasilyevich
Published: May 2024

The subject of the study is informatization in military affairs, the object of the study is possible ways to control the enemy through intentional and targeted distortion of information about their troops, goals and conditions of action. The author examines in detail such aspects of modern warfare as multi-domain, with a significant shift in emphasis in the sphere of information warfare. As the experience of local wars and armed conflicts of the last decade shows, the forms of their conduct differ significantly from the "classic" wars waged until the end of the XX century. The informatization of the battlefield made it possible to switch to such form of use of troops (forces) as network-centric actions. But the expansion of capabilities, the improvement of technologies of warfare, in accordance with the laws of dialectics, generates certain vulnerabilities. These vulnerabilities manifest themselves in the same area where the strengths are located – in the field of informatization of military operations. Based on this, special attention is paid to assessing the impact of informatization on the adequacy of decisions, primarily in terms of possible vulnerabilities of the management process. Using general scientific research methods: analysis and synthesis, the author, based on the analysis of the main trends of modern armed confrontation, synthesized a description of possible vulnerabilities when using automated control systems, formulated the task of developing a mathematical apparatus for the formation and evaluation of the reliability of information about the opposing systems. This is not about physically changing information in the automated control systems of the enemy: this task is technically difficult, but relatively simple from the point of view of algorithmization.

The object of this work is tax control in the Russian tax system, and the subject is the organization and implementation of tax control in the context of digitalization of the Russian economy. In their research, the authors consider in detail the topical issues of the organization of tax control in modern conditions of digitalization of the economy, identify the main problems and propose ways to solve them. It is noted that in light of the rapidly changing technological environment, tax authorities must adapt and use innovative technologies to ensure effective and transparent tax control. Digital security and efficient use of data are also important aspects. The authors propose to explore the possibilities of using technologies to analyze large amounts of data, identify potential tax violations and ensure more accurate and effective control. This can significantly improve the tax collection process and reduce the burden on tax authorities, freeing up time for more in-depth analysis and strategic planning. The study of the organization of tax control in the digital economy has a high relevance and novelty. In the modern development of technology and digitalization, more and more companies carry out their activities through online platforms and electronic systems. This creates new challenges and difficulties for tax authorities, as traditional methods and approaches to tax control may be ineffective. An effective tax control system is the basis for the economic well-being of the state, promotes the development of entrepreneurial activity and ensures stability. The study highlights the need to improve regulatory regulation in the field of detection and disclosure of economic and tax crimes. It also requires the introduction of modern methods and means of detecting and disclosing such crimes, improving cooperation and information exchange between tax authorities, law enforcement agencies and entrepreneurs.

The subject of this article is the problem of the introduction of distance learning technologies in the process of education by convicts in the context of digital transformation. The article examines the main normative legal acts regulating the right of convicts to education; characterizes the problems existing in the penitentiary system when convicts receive education; examines the experience of using distance learning technologies by foreign countries, evaluates the possibility of applying their experience in the Russian penitentiary system. The relevance of the topic is due to the fact that the possibility of convicts receiving education in Russia applies only to certain categories of convicts, which is considered ineffective in the current conditions of humanization. In addition, remote technologies that have proven their worth and importance are practically not used in the modern penitentiary system, which is seen as a serious disadvantage and requires special attention. The main purpose of the study is to develop the possibilities and prospects for the implementation of the process of distance learning of convicts in Russia. Along with general scientific methods, the authors also used special legal methods (system-analytical, comparative legal, statistical) in the preparation of this article. Based on the conducted research, prospects have been identified that contribute to the successful introduction of distance learning technologies into the Russian penal system. The optimal way to solve the stated problems will be the legislative regulation of the possibility of obtaining education using distance learning technologies for all categories of convicts, as well as the development of effective programs and courses through which persons serving imprisonment could gain knowledge and master a particular profession.
