Personnel certification as a component of the business process of development of employees of it companies
Authors: Petrenko Oleksandr , Kotlyk Andrii
Published: May 2024

The article examines the main theoretical aspects of employee certification. It analyzes the approaches to applying the definition of certification as an element of professional training for employees, as well as a permit to use specific software or other tools that are an element of protection and regulation in the labor market. Based on various sources, the author systematizes the classification of certification types according to various division criteria, in particular: by type, by the number of levels, and by the origin of materials. Based on the current situation in the IT industry, a list of advantages and possible disadvantages of certification of employees of modern Ukrainian IT companies is determined. The primary certification areas are identified: «soft skills», «hard skills», and the subject area of the unit's functioning. Among the main advantages of certification of employees of IT companies are the following: advanced training of current staff, standardization of own training programs, the ability to prove to external stakeholders the level of staff qualifications, and the simplification of recognition of the level of skills in certain areas. Typical shortcomings in the certification process are that the knowledge and skills acquired during certification are not always used in practice; there is no standard international certification for many industries/topics/elements; some courses are extensive and time-consuming; and some programs require certain significant restrictions (experience, qualifications). The multi-stage certification business process involves determining the need for certification by collecting the necessary information. Based on the list of potential areas of certification, available resources, and other components, an annual certification program is formed, and employees are motivated to improve their knowledge and skills. In the professional certification process of IT company employees, current feedback and, most importantly, summarizing the certification results and fair rewards based on its results are essential. The article provides conclusions and prospects for further research.

Analysis of the operation of the microprocessor control system of a bridge crane using optimum control laws
Authors: Antoshchenkov Roman , Svirgun Volodimir , Svirgun Olga , Svirgun Valentyn
Published: May 2024

This work presents the results of studies on the influence of the error of the main parameters of the bridge crane on the quality of optimal control. The quality of control refers to the exact positioning of the load at the stopping point and the magnitude of the final fluctuations of the load after the crane stops. The concept of optimal control is based on L.S. Pontryagin's maximum principle, which is when the goal is achieved by switching the acceleration-braking control of the load suspension point according to a specific algorithm. To achieve the maximum speed of operation of the crane, certain restrictions and conditions have been removed, namely, the refusal to eliminate load fluctuations during crane acceleration, which simplifies the subsequent elimination of load fluctuations during crane braking. However, this is an unnecessary waste of time, and therefore, acceleration is carried out at the maximum possible acceleration without eliminating load fluctuations. Of course, at the same time, significant fluctuations in the cargo occur, and they continue throughout the entire time the crane is moving. Moreover, the final goal is achieved only at the end of the cycle by switching the acceleration-deceleration modes - the cargo is delivered precisely to the specified point without fluctuations after the crane stops. A PC program that generates optimal control laws for a specific crane has been developed. This program can be used for any lifting machine where the suspension point moves in a straight line, and flexible load suspension is used, such as overhead or gantry cranes, hoists, etc. The results of the research were tested on several objects: a 0.5t crane, a 5t bridge grab crane, and models of bridge cranes. In each case, a good coincidence of theoretical and experimental results was observed, resulting in effective management of the object. The original microprocessor system implemented the optimal control laws, built first based on the MKP-1 microcontroller and then based on Arduino. However, a good result is guaranteed only if the fundamental parameters of the crane coincide with the theoretical ones. This is not easy to achieve during the actual operation of the crane. They vary within a specific range. The article examines how the error in each of the main parameters of the crane affects the result and how the control system can be improved to reduce the negative impact to a minimum.

Authors: Singh Nishant , Mahato Ashis
Published: May 2024

Cultural elements in folktales can manifest through idiomatic expressions, metaphors, proverbs, or references to specific historical events or figures. Each of these elements holds significant cultural value, enriching the story and providing insights into the community's collective experiences and values. In India, folktales are cherished by millions for their entertainment and aesthetic value. These tales are typically passed down orally from one generation to the next, and in more recent times, they may also be found in written form. Folktales from different regions reflect the thoughts, traditions, and culture of their people, providing both entertainment and insight into their past and present customs. Bihar is one of the most important states of India, located in the eastern region of the country, and has a rich tradition of folk culture. We often observe the representation of animal characters in folktales. In the context of the folktales of Bihar, we can also observe the depiction of different types of animal beings. The purpose of this study is to analyze how the animals are represented in the context of folktales of Bihar. To undertake this study, we need to utilize the descriptive analysis approach.

Authors: Hamid Ahmed A. A.
Published: May 2024

This field experiment, was conducted to investigate a comparison of two methods for harvesting potatoes: mechanical and handy when using moldboard and chisel plow for primary tillage and three different distances for planting tubers in the rows 15, 25, and 35 cm in silt clay loam soil south of Baghdad. The factorial experiment followed a randomized complete block design with three replications using L.S.D. 5 % and 1 %. Mechanical harvest recorded the best valid potato tubers at 88.78 %, marketable yield of 31.74 ton. ha-1, efficiency lifted 95.68 %, tubers damage index 28.41, speeding up the harvesting process and reducing time and effort. Handy harvest gave the least damage to potato tubers, 6.02 %, and unlifted potato tubers, 4.32 %. However, this method requires effort and more specialized labor, whether from men or young women, and leaded to delays in the harvesting process. Regarding planting distance of 15 cm between one tuber and another gave the highest total productivity, 46.92 ton. ha-1 and the greatest number of plants, but most of the tubers were small in size. A planting distance 25 cm produced good quality in size of potatoes with yield of 36.19 ton. ha-1, 90.99 % best valid tubers, 5.43 % least total damage tubers, 3.57 % least unlifted potato, 96.42 % best efficiency lifting, and least tuber damage index 22.39. Most interaction among the treatments was significant. The most influential factor in the experiment traits was the planting distances of potatoes in the rows. The shape of the potatoes was Spheroid. Mechanical potato harvesting saves effort saves effort, time, harvest speed, reduce the labors and increasing efficiency.
Evaluating Land Suitability for Wheat Cultivation Criteria Analysis Fuzzy-AHP and Geospatial Techniques in Northern Basrah Governorate.
Authors: Almayyahi Mustafa S. A. , Al-Attab Salah M. S.
Published: May 2024

Land suitability assessment is essential for planned land management strategies aimed at preserving soil and increasing productivity while ensuring sustainable agricultural production. Land degradation resulting from poor land management and fallowing practices typically leads to low land productivity in Iraq. To maintain agricultural productivity in the targeted area, agricultural requirements must align with available resources through land suitability analysis. In the northern region of Basrah Governorate in Iraq, the study focused on integrating GIS-based land suitability analysis with the fuzzy-analytical hierarchy process (F-AHP) approach. The analysis revealed varying suitability categories throughout the study area, with the largest proportion of unsuitable areas found in category N2, covering 31,202.36 hectares (37.76%), and category N1, currently unsuitable, covering an area of 19,956.24 hectares (24.15%). On the other hand, the moderately suitable category (S3) covered 8,297.26 hectares (10.04%), while the moderately suitable category (S2) covered 23,177.79 hectares (28.05%) of the total study area. No highly suitable lands were identified. The key determining factors for the suitability of lands for wheat cultivation were high values of electrical conductivity, carbonate minerals, bulk density, and low organic carbon content. Most agricultural lands are being used in a manner that contradicts their suitable potentials in the study area. Therefore, the pattern of agricultural land use needs to be adjusted based on their current potentials to reduce soil degradation.

At the input stage, the active participation of the community in formulating work programs has reflected an inclusive approach that considers the needs and aspirations of the residents. In terms of outputs, tangible progress has been made in developing village infrastructure and health services, although some programs have yet to materialize fully. The impact of the Village Government Work Plan implementation has been positively felt by the community, especially in improving road infrastructure which enhances access and mobility. These results show that the integration of SDGs into the Popalia Village Government Work Plan has successfully created changes impacting the community’s quality of life. However, there are still challenges to overcome for more comprehensive success. Therefore, it is recommended that the Popalia Village Government intensify efforts to complete the unimplemented Village Government Work Plan programs, prioritizing initiatives that directly impact improving the community’s quality of life. Relevant community organizations are expected to support the village government through collaboration and mobilizing additional resources to ensure the sustainability and expansion of programs aligned with the SDGs. The villagers are also encouraged to actively participate in every stage of the Village Government Work Plan, from planning to evaluation, to ensure that the initiatives align with their needs and aspirations. Enhancing communication and coordination among all stakeholders is vital to overcoming existing challenges and maximizing the positive impact of integrating SDGs into the development of Popalia Village.

Interaction of norsecurinine-type monomeric and dimeric alkaloids with α-tubulin: a molecular docking study
Authors: Vergoten Gérard , Bailly Christian

Aim: New microtubule-targeting agents are needed to improve cancer treatment. The recent characterization of the anticancer alkaloid securinine as a tubulin-binding agent prompted us to explore the interaction of related monomeric and dimeric analogues with tubulin. The interaction between the α/β-tubulin dimer and alkaloids fluevirines A–F and flueggenines A–I, isolated from the bush Flueggea virosa (Roxb. ex Willd.) Royle, was investigated using molecular docking. Methods: Two molecular models were initially compared for the binding of securinine to α/β-tubulin. The pironetin-binding site model (5FNV) was selected for the subsequent docking analysis with all compounds. Empirical energies of interaction (ΔE) were measured and compared. Results: Fluevirine A has been identified as a potent tubulin binder. This dimeric alkaloid formed more stable complexes with tubulin than the monomeric counterparts, such as fluevirines B–D. The bis-indole derivative fluevirine E also provided more stable complexes than (nor)securinine. The study was extended to the dimeric alkaloids flueggenines A–I and three compounds were identified as potential tubulin binders: the polycyclic product flueggenine B, the norsecurinine-indole hybrid flueggenine E, and the norsecurinine dimer flueggenine I. This later compound proved to be well adapted to fit into the pironetin site of tubulin, extending its two norsecurinine units between the colchicine-binding area and the pironetin site, in close proximity to the pironetin-reactive cysteine-316 residue. Structure-binding relationships were delineated. Conclusions: The study identifies the dimeric alkaloids fluevirine A and flueggenine I as potential α-tubulin binding agents. For the first time, dimeric alkaloids including two C-C connected norsecurinine units are characterized as tubulin ligands. The study contributes to a better understanding of the mechanism of action of Flueggea alkaloids and should help the design of anticancer analogues targeting the pironetin site of α-tubulin.
Ajaran “Pembenaran” pada Komunitas Qumran: Sebuah Eksegesis terhadap 1QHa 9:22-35

Naskah Hodayot yang ditemukan di gua pertama di Qumran, yang diberi teknis pencatatan 1QHa 9:22-35, merupakan lagu-lagu ucapan syukur yang memiliki karakter "doa pengakuan dosa" dan bersifat eskatologis-apokaliptis. Kelompok pengampu (milieu) dari Hodayot adalah kelompok maskilim yang memiliki karakter apokaliptis. Pesan teologis dari hodayot adalah ajaran pembenaran yang sangat mempengaruhi teologi Paulus. Ajaran pembenaran ini sangat memengaruhi teologi antropologis yang berbanding terbalik dengan kedaulatan dan kemuliaan Allah, yang harus diwartakan. Karakter ini juga sangat mempengaruhi teologi Paulus pada khususnya dan teologi Perjanjian Baru pada umumnya.
Problems Of Defining The Concept Of Military Property As The Subject Of Military Criminal Offenses
Authors: VOITSESHCHUK Artur
Published: May 2024

The concept of «military property» is investigated, and several shortcomings of its normative definition are identified. Based on the analysis of the Law of Ukraine «On the legal regime of property in the Armed Forces of Ukraine,» laws of Ukraine regulating the activities and legal status of other military formations, some bylaws contradictions were revealed regarding the recognition of the military property of the National Guard of Ukraine, the Security Service of Ukraine, the State Border Guard Service of Ukraine, the State Service for Special Communication and Information Protection of Ukraine, as well as the property of the State Special Transport Service, in addition to the weapons and ammunition assigned to its units. In addition, the problem of interpretation of «the concept of «military property» is formed by the use in its normative definition of the phrase «assigned to...», which calls into question the recognition as military property, material property, property transferred as charitable assistance, property received as a result of economic activity, «trophy» property, etc. These problems may make it difficult to apply the norms on criminal liability provided for in articles 410-413 of the Criminal Code of Ukraine. The study also found that property may lose its military status if written off or alienated from the moment of approval or signing of the relevant official documents. At the same time, the write-off of property does not lead to the loss of its military status if, as a result of the write-off, it is transferred to another accounting category. Separate property is subject to write-off immediately after its transfer to use. Therefore, from the moment of such write-off, it loses its military status and cannot constitute the subject of criminal offenses provided for in articles 410-413 of the Criminal Code of Ukraine. Based on the study results, we propose to introduce amendments to regulatory legal acts regulating the legal regime of military property, which would extend their effect to all military formations created under the legislation of Ukraine. Changes to the normative definition of the «military property» concept are also proposed, which consist of recognizing any property in the records of a military formation or any property that has come into the possession of such a formation.
The Right To Respect For Private And Family Life For Individuals Sentenced To Life Imprisonment Aligns With The European Court Of Human Rights Practice Concerning Ukraine: Conditions Of Legal Limitation And Classification Of Violations
Authors: BRYCH Larysa
Published: May 2024

Individuals sentenced to life imprisonment in Ukraine according to Articles 3, 30, 31, 32 of the Constitution of Ukraine, and Article 8(1) of the Convention for the Protection of Human Rights and Fundamental Freedoms of 1950 and other international treaties, have the right to respect for their private and family life. The legislation of Ukraine regulating the regime of serving punishment by this category of convicts, in terms of providing opportunities for convicts to exercise this right, did not correspond to European standards in many aspects. Researchers have considered the Criminal Executive Code of Ukraine as the sole source of law, which comprehensively regulates the content and scope of rights of convicts in Ukraine, including respect for private and family life. Under the influence of demands addressed to Ukraine from the European Court of Human Rights, Ukraine's criminal and criminal-executive law changed, approaching European standards, but complete compliance has not been achieved yet. The realization of the right to respect for private and family life by individuals deprived of liberty, by the established practice of the European Court of Human Rights and recommendations provided by the Committee of Ministers of the Council of Europe in the European Prison Rules, is carried out through contacts with the outside world, encompassing a specific set of concrete opportunities. The right to establish and develop relationships with other people and the outside world is not absolute. It can be restricted according to the conditions of serving a sentence of life imprisonment. The European Court of Human Rights has developed an established practice in cases brought by individuals deprived of liberty. This practice includes legal positions reflected in decisions regarding other states and decisions concerning Ukraine. This concerns the delineation of the scope of Article 8 «Right to respect for private and family life» of the Convention for the Protection of Human Rights and Fundamental Freedoms with the spheres of action of its other articles, including Article 3 «Prohibition of torture». In addition, considered the legality of the conditions limiting the right to respect for private and family life within the regime framework of serving sentences by convicts and the types of violations of this right by states. In this article, this such practice is analysed and summarized.
