Authors: Shaw L. , Domanski S. , Freeman A. , Hoffele C.
Published: December 2024

The purpose of this study was to investigate and evaluate the current workplace management of rotator cuff injuries in a manufacturing plant. The secondary aims were to examine the impact of the company's return-to-work processes, compare outcomes to current industry standards for work (re)entry and to identify the components that characterized this workplace--based return-to-work (RTW) program. This investigation involved a case study approach comprised of an examination of the program context using interviews, onsite visits, a document review and a retrospective analysis of the RTW experiences of 184 workers with shoulder injuries. Findings revealed that the workplace-based RTW program was consistent with and shaped by the organizational culture of problem solving, knowledge exchange and equitable participation of workers, supervisors and health professionals. These components contributed to the program in achieving the following outcomes for workers with shoulder injuries. One-third of workers were placed on modified duties within three days, 56% of workers who engaged in an early RTW program returned to work within one month. Overall, 87.8% of workers with rotator cuff injuries successfully returned to pre-injury work. The implications of developing capacity for workplace-based programs to manage injuries at work are discussed.
Case study: Musicians' playing-related injuries
Authors: Guptill Christine , Golem Matthew Bruijn
Published: December 2024

Professional and student musicians are at high risk of acquiring a playing-related injury at some point in their careers. Yet, specialized healthcare for musicians is scarce and expensive for most self-employed musicians. Diagnosing these injuries is challenging, and simply taking a break from an activity that has caused physical problems does not address the ergonomic and biomechanic causes of the problem. Under these circumstances, it is not surprising that musicians are reluctant to seek care, and when they do, lack trust in the care that is provided to them. This article is a case presentation of the experiences of a graduate student musician studying performance at a North American university. A narrative style is used to reflect the quality and nature of experiences this musician encountered, followed by a discussion of how to advance a more participatory and holistic approach to enabling return to function.
Disclosure of mental health
Authors: Hatchard Kathy
Published: December 2024

As today's workplaces strive toward a climate of inclusiveness for persons with disabilities, much work remains for employers in developing a process to achieve this ideal. While survivors of mental illness are encouraged to disclose related concerns to their employer, such sharing of personal information remains daunting. Similarly, employers attempting to assist the process are often awed by the extent of collaborations involved in integrating employees with mental health issues back to work as well as concern about compliance with human rights legislation. Needed accommodations in terms of approach to the work itself are often simple; however substantiating the need for adjustments is more complex. This case study introduces a model to support the development of shared goals and shared understandings for return to work (RTW) among workers with mental health concerns, employers, co-workers and therapists. The model of occupational competence is used as a basis to guide dialogue, identify challenges and generate solutions that take into consideration a worker's preferences, sensitivities, culture and capacities in relationship to the occupational demands in a given workplace environment. A case study is used to demonstrate the potential utility of the model in assisting stakeholders to strengthen collaborations and partnering to achieve a shared understanding of worker and workplace needs.
Moving toward virtual interdisciplinary teams and a	multi-stakeholder approach in community-based return-to-work care
Authors: Brunarski David , Shaw Lynn , Doupe Lisa
Published: December 2024

More efforts are needed to help stakeholders who are geographically isolated from one another become more collaborative in their approach to return-to-work (RTW). A review of the literature on team processes, and insights from the experiences of a federally funded Round Table Project on Safe and Timely Return to Function and Return to Work were used to inform strategies that might enhance collaboration among health professionals and stakeholders in injury and illness management and return-to-work. A case study serves to highlight the individual, identifies the problem and provides a potential solution at the broader service and system levels. It becomes evident that there is a need for a common language as well as policies that emphasize the importance of fostering awareness of interprofessional potentials and contributions of all stakeholders. Establishing shared goals, and building capacity for sustaining collaboration when multi-stakeholders do not function in the same physical location, but work virtually, might maximize effectiveness, efficiency and productivity.
A longitudinal study of the relationship between empowerment and	burnout among registered and assistant nurses
Authors: Hochwälder Jacek
Published: December 2024

The relation between empowerment and burnout was investigated using a two-wave and two-variable panel model. A questionnaire was completed on two occasions, one year apart, by 1,356 nurses. The paths in the model were estimated using regression analyses and the following results were obtained: (a) empowerment is a stable state; (b) higher levels of empowerment are related to lower levels of burnout, when empowerment and burnout are studied at the same point in time; (c) higher prior levels of empowerment can be associated with higher later levels of burnout, when empowerment and burnout are studied at different points in time; (d) for assistant nurses, but not for registered nurses, prior higher levels of burnout resulted in lower later levels of empowerment, indicating a reciprocal relation between the two concepts. The results imply that what is a protective factor from a cross-sectional perspective may be a risk factor from a longitudinal perspective.

Authors: Mohan G. Madhan , Elangovan S. , Prasad P.S.S. , Krishna P. Rama , Mokkapati Anil Kumar
Published: December 2024

Global competition in manufacturing sector demand higher productivity levels. In this context, workers in this sector are set with high output targets, leading to job strain. In addition to the strain, hazardous conditions also prevail in some of the manufacturing processes like foundry activities. This paper attempts to appraise the prevalence of job strain among foundry shop floor workers in India with the help of Demands-Control model [8]. In this study, data was collected through a survey using 49-item Job Content Questionnaire (JCQ) [9], a widely used and well-validated test for job strain. Then the data was subjected to statistical analysis after ascertaining the reliability. This survey has revealed that 25% of workers in foundry were experiencing high job strain. Hazardous working conditions, limited decision making authority, etc. appear to be the main contributing factors for the higher levels of strain.
Carrying loads and postural sway in standing: The effect of load	placement and magnitude
Authors: Zultowski Ilyse , Aruin Alexander
Published: December 2024

This study investigated the effect that load magnitude, load location, and the dimensions that the base of support have on postural sway in standing while wearing a backpack, single strapped bag, briefcase, or purse. Subjects were instructed to carry a load of 10% or 20% of their body weight with either their feet spaced shoulder width apart or together for a period of 45 seconds. Medial/lateral and anterior/posterior center of pressure (COP) displacement and COP velocity were calculated. Overall, it was found that an increase in load magnitude produced an increase in postural sway and velocity of COP. In addition, a large increase in the medial/lateral COP velocity was observed when subjects carried a briefcase, single strapped bag, or purse. Additionally, a larger COP sway was recorded in conditions of standing with decreased base of support (feet together). These findings suggest the importance of considering the way we carry loads in order not only to place less strain on the body and to minimize our efforts, but to optimize postural control as well.

Published: December 2024

In the area of work rehabilitation, many decisions about future interventions for the client are based on the results of various kinds of assessments. Therefore, it is important that the assessment instruments used are adequate, useful, and reliable. The purpose of this study was to investigate the content validity and utility of the instrument Assessment of Work Performance (AWP) which is used to assess an individual's observable (working) skills during work performance, i.e. how efficient and appropriate a client performs a work activity. A questionnaire was answered by 67 respondents who used the AWP in various work rehabilitation settings in Sweden. The result indicates content validity and utility for the AWP that supports further testing of the instrument.

Published: December 2024

This study is a prospective multicentre cohort study entitled Work and Health in the Processing and Engineering Industries, the AHA Study (AHA is the Swedish abbreviation for the study). Four large workplaces in Sweden participated during the years from 2000 to 2003. The present report has two objectives: (1) to present a comprehensive occupational health intervention programme and (2) to evaluate this programme with a focus on lifestyle (smoking and exercise), health related quality of life (HRQoL) and sick leave. Interventions were provided on an individual and group level, including evidence-based methods for four health/focus areas (individual level) and a group intervention based on a survey-feedback methodology. The analyses in this report were exclusively employed at an organizational level. The proportion of smokers decreased at three companies and the course of the HRQoL was advantageous at two of the companies as compared to a gainfully employed reference group. A significant decrease in sick leave was revealed at one company, whereas a break in an ascending sick-leave trend appeared at a second company as compared to their respective corporate groups. This comprehensive workplace intervention programme appears to have had positive effects on smoking habits, HRQoL and sick leave.

Authors: Boeltzig Heike , Timmons Jaimie Ciulla , Marrone Joe
Published: December 2024

Barriers to seamless service delivery between workforce development and mental health systems of care have kept both entities from maximizing their potential in regards to employment for job seekers with mental illness who are capable of work and seeking employment. Using a multiple case study design, this study examined the nature of collaboration between workforce development and mental health systems to understand the policies and practices in place to assist individuals with mental illness to find and keep work. The paper presents innovative strategies that involved staff from both workforce development and mental health agencies. Findings from this research identified the following collaborative strategies: (a) the creation of liaison positions and collaborative teams; (b) staff training on mental health and workforce issues; and (c) multi-level involvement of individuals with mental illness. Implications for workforce professionals are offered as a way to stimulate implementation of such strategies.
Physiological stress monitoring of postmen during work
Authors: Theurel J. , Offret M. , Gorgeon C. , Lepers R.
Published: December 2024

The purpose of the present study was to characterize the physiological demands of postmen during a work day composed of mail sorting (inside work, IW) and cycling distribution (outside work, OW). Two groups of postal workers were constituted according to the geographical profile of their distribution courses: flat profile (FP; n = 7) vs hilly profile (HP; n = 7). Heart rate (HR) was recorded and energy expenditure (EE) was estimated during both IW and OW. EE was, on average, 1795 ± 497 Kcal per workday. HR was higher (p < 0.001) during OW (104 ± 14 bpm) than during IW (80 ± 7 bpm). HR was highest during the cycling part (109 ± 13 bpm). Average HR was greater (p < 0.001) for HP (112 ± 9 bpm) than for FP route (95 ± 8 bpm). On average, the workload of postmen could be considered as moderate. Nevertheless, the physiological demand greatly increased during the cycling part of OW, especially with hilly geographical profile. The greater physiological strains during the cycling should be factored into the improvement of work organization and delivery materials (e.g. bicycle) for postal workers.

Authors: Strauser David R.
Published: December 2024

Research has suggested that individuals who experience work related injuries may be at an increased risk for developing trauma symptoms or Posttraumatic Stress Disorder (PTSD). The purpose of this article is to provide a brief overview of PTSD from both a categorical and dimensional perspective and discuss implications for rehabilitation planning with workers with industrial injuries. The negative impact of trauma symptoms and PTSD is profiled according the following four areas that are important for effective career and vocational behavior: (a) making occupational adjustments, (b) adjusting performance to meet specific work demands, (c) utilizing appropriate social and interpersonal skills in the work setting, and (d) meeting the production and time requirements associated with the specific job. Recommendations are then offered to increase the effectiveness of rehabilitation professionals working with industrial injured workers who may be experiencing trauma symptoms or PTSD.

A systematic review of the development of work rehabilitation in	Mainland China
Authors: Xu Yanwen , Tang Dan
Published: December 2024

Objectives: A systematic review was conducted on the literature regarding the development of work rehabilitation in Mainland China.

Method: Two databases, one in Chinese and one in English, were used for searching reports published between 1994 and 2004 on work rehabilitation services provided in medical institutions to patients with disability associated with various types of injuries.

Results: A total of 66 papers were identified, and only 14 studies matched the inclusion criteria for this review. There was strong evidence that work rehabilitation services provided in the medical institutions for disability were underdeveloped in Mainland China; and misunderstandings of work rehabilitation were widespread.

Conclusions: Work rehabilitation is still a fairly new concept in Mainland China. The importance of work rehabilitation is not considered/realized in medical institutions during the process of medical treatment and rehabilitation. Further studies on work rehabilitation provided in medical institutions should be conducted to develop appropriate local technologies and services for the patients.

Authors: Welch Laura S. , Haile Elizabeth , Boden Leslie I. , Hunting Katherine L.
Published: December 2024

Background: To investigate the intersection of aging with work limitations, chronic medical and musculoskeletal conditions, and physical functioning we undertook a cross-sectional study of U.S. construction roofers who were current union members between the ages of 40 and 59.

Methods: Participants were asked about the presence of medical conditions and musculoskeletal disorders (MSDs); the Work Limitations Questionnaire, the SF-12, and other validated assessments of social and economic impact of injury were included.

Results: Sixty-nine percent had at least one of these conditions in the previous two years; 31% missed work. Workers with medical and musculoskeletal conditions were older, had the highest prevalence of work activity limitations, and had the lowest SF-12 scores.

Conclusions: Older age was associated with the presence of a medical condition, and with reduced physical functioning. Medical and musculoskeletal conditions were strongly associated with work limitation, missed work, and reduced physical functioning. Older workers may be at higher risk of disability retirement compared to younger workers with similar medical conditions and work limitations.

Authors: Kawada Tomoyuki , Suzuki Shosuke
Published: December 2024

Background: The physical symptoms and mental health status of 3,447 men working in a dairy product company were evaluated by a health questionnaire, the Todai Health Index (THI). The purpose of this study is to determine the relationship between job content and subjective health status.

Method: The authors conducted a cross-sectional study. Thirty-three branches of the company are distributed throughout Japan. The subjects ranged in age from 18 to 59 years old. The THI is composed of 130 questions and each subject's physical and mental health status was evaluated based on the scores in 13 specific scales. The subjects' jobs were classified into three categories: 1 production process work; 2 clerical or technical work; 3 transportation or sales work. Subjects grouped into the clerical or technical work category were set as the control group, because the authors speculated that the lowest workload was observed in group of clerical or technical work.

Results: The scores in each of the THI scales were compared among workers in the three job categories stratified by the age group (10-year age groups). The transportation or sales workers began to show high scores for irregularity of lifestyle from their 30's, and this was maintained until subjects' retirement from the company. In addition, the same group also began to show higher scores for physical symptoms, such as vague complaints, respiratory complaints, and eye complaints from their 40's and higher scores for mouth and evacuation and digestive complaints from their 50's.

Conclusions: Transportation or sales workers should receive adequate health care to prevent a high prevalence of physical and/or illness.
Development of risk assessment tool for foundry workers
Authors: Mohan G. Madhan , Prasad P.S.S. , Mokkapati Anil Kumar , Venkataraman G.
Published: December 2024

Occupational ill-health and work-related disorders are predominant in manufacturing industries due to the inevitable presence of manual work even after several waves of industrial automation and technological advancements. Ergonomic risk factors and musculoskeletal disorders like low-back symptoms have been noted amongst foundry workers [20].

Objective: The purpose of this study was to formulate and develop a Physical Effort Index to assess risk factor.

Scope: The questionnaire tool applicable to foundry environment has been designed and validated. The data recorded through survey across the foundries has been subjected to regression analysis to correlate between proposed physical effort index and the standard Borg's Ratings of Perceived Exertion (RPE) scale [3].

Results: The physical efforts of sixty seven workers in various foundry shop floors were assessed subjectively. The 'Job factors' and 'Work environment' were the two major parameters considered in assessing the worker discomfort level at workplace. A relation between Borg's RPE scale and the above two parameters were arrived at, through regression analysis.

Conclusions: The study demonstrates the prevalence of risk factors amongst foundry workers and the effectiveness of the proposed index in estimating the risk factor levels.

Relevance to the industry: The proposed tool will assist foundry supervisors and managers to assess the risk factors and helps in better understanding of the workplace to avoid work-related disorders, ensuring better output.

Ergonomics for schools
Authors: Legg Stephen , Jacobs Karen
Published: December 2024

Ergonomics in Schools has focused on micro-ergonomics issues such as mismatch between student body sizes and their desks and chairs, the weight of schoolbags and the prevalence of musculoskeletal disorders amongst school students. Very little of this has been turned into practice. Although advances in this context are being made by the International Ergonomics (IEA) Technical Committee (TC) on Ergonomics for Children in Educational Environments (ECEE), the UK Ergonomics Society Special Interest Group on Ergonomics for Schools and the New Zealand Ergonomics Society Ergonomics/Human factors in Education (EHFIE) Special Interest Group, there has been less focus on macro-ergonomics issues such as learning environments, ergonomics pedagogy and curriculum content/structure. This commentary reviews micro-ergonomics aspects of `Ergonomics in schools' and argues in favour of a new direction: macro-ergonomics for schools, or educational ergonomics in which ergonomists seek to integrate ergonomics into national educational curricula in concert with Ministries of Education and also via inclusion of ergonomics modules in teacher training.
Universal Wong Formula for Capture Cross Sections from Light to Super-Heavy Systems
Authors: Wang Ning , Yao Hong
Published: December 2024

A universal Wong formula is proposed with refined model parameters for a systematic description of the capture cross sections for heavy-ion fusion reactions from C+C to Ni+U, in which the barrier parameters and the barrier distribution are determined by the entrance-channel nucleus-nucleus potential based on the Skyrme energy density functional. With introducing a constraint to the width of the barrier distribution and a pocket-depth dependent barrier radius, the capture excitation functions for a number of fusion reactions involving different nuclear structure effects are remarkably well reproduced, particularly for the reactions between light nuclei and those forming super-heavy nuclei. The systematic decreasing behavior of the geometric radii with the depth of capture pocket due to the influence of deep inelastic scattering is clearly observed in the TDHF calculations for super-heavy systems. The predicted capture cross sections for 54Cr + 238U at above barrier energies are evidently smaller than the corresponding results of more asymmetric projectile-target combination 50Ti + 242Pu due to the shallower capture pocket in Cr+U.
Entangled Simultaneity: Testing Lorentz and Light-Speed Invariance with Quantum and Classical Entanglement
Authors: Spavieri Gianfranco , Mendoza Sánchez Juan Carlos , Carrasquero Ramón , Flores G. Andres J. , Nieves Kevin J Durán , Contreras Antonio
Published: December 2024

In a rod of length AB \(= L\), rotating uniformly, any two spatially separated points along the rod are connected in a way that shows analogies with the quantum entanglement of the spin of particles. This ”classical entanglement” reflects the simultaneity preset in the system, which can be used for syncing two distant clocks, one at A and the other at B. Since it differs from Einstein synchronization, this procedure can be adopted for testing the one-way light speed and Lorentz invariance. Applications to optical Sagnac effects confirm that a consistent interpretation requires the adoption of absolute versus relative simultaneity.
Longitudinal Doppler for Observers in Uniform Acceleration
Authors: Quattrini Stefano
Published: December 2024

This study derives the exact frequency observed for electromagnetic waves emitted during uniform acceleration. In the classic case the frequency observed is typically calculated using the formula f = f0 (1+gH/c2) where ‘f0‘ is relevant to the source and g represents the constant acceleration. At least in Feynman’s Lectures, such formula is derived directly as a first order approximation from the relativistic Doppler effect. Relativistic relations are used to determine the exact light-time between the source and observer. It is found that, if g represents the proper acceleration, the frequency ratio remains the same as in the classic case (1+gH/c2). Being that value exact, no higher order relation exists where it can be derived from. The absence of higher order terms depends on a peculiar compensation of two relativistic effects.

Published: December 2024

This study investigates the anti-ulcerogenic properties of Zingiber zerumbet using a rat model subjected to ulcerogenic agents. The hydroalcoholic extract of Zingiber zerumbet was evaluated for its efficacy in mitigating ulcer formation, measured through the number of ulcers, ulcer index, and gastric pH levels. Results demonstrated that the extract significantly reduced both the number of ulcers (from 9.80 ± 0.75 in the control group to 0.25 in the treated groups) and the ulcer index (from 6.25 ± 0.30 in the control to 0.52 ± 0.15 in the extract-treated group). Additionally, the gastric pH improved markedly, with treated groups showing pH levels of 6.85 ± 0.75 and 6.75 ± 0.35, compared to 3.45 ± 0.32 in the control group. The qualitative phytochemical analysis revealed the presence of flavonoids, saponins, and alkaloids, which are known for their therapeutic effects. These findings underscore the potential of Zingiber zerumbet as a natural remedy for gastric ulcers, providing a basis for further research into its active constituents and mechanisms of action

SDR-adatfolyam feldolgozása korszerű módszerekkel
Authors: Farkas Gábor
Published: December 2024

Napjainkban a félvezető technológia fejlettsége már lehetővé teszi, hogy SDR-ek segítségével rádiójeleket nagy sávszélességgel mintavételezzünk és rögzítsünk. Ennek számos előnye van, viszont a sávszélesség növekedésével a feldolgozandó adatmennyiség olyan mértékűre bővülhet, hogy azt hagyományos számítógéppel már nem lehet valós időben feldolgozni vagy letárolni. Így célszerűvé válik olyan programozható célhardverek alkalmazása, mint például az FPGA-k, amelyekkel a jelfeldolgozás hatékonysága jelentősen növelhető. Ezekben az eszközökben rejlő lehetőségek kihasználásához mélyreható szakmai ismeretek szükségesek. Kutatásaim és tapasztalatom alapján nincs egységes módszer az FPGA-k témámhoz kapcsolódó funkcióinak kialakítására vonatkozóan, ezért szükségesnek látom, hogy a szakirodalom tanulmányozását követően olyan módszertant alakítsak ki, amellyel az FPGA-val történő nagy sebességű adatfogadást képesek lehetünk optimalizálni.

До таких факторів віднесено: зменшення частки доларів та збільшення часток нетрадиційних резервних валют (китайського юаня, південнокорейської вони, сінгапурського долару і скандинавських валют.); намагання країн, що розвиваються емітувати більше боргових інструментів у валютах країн-кредиторів, зокрема таких як Китай; потенційна конкуренція між фіатними та цифровими грошами, створення платіжних систем для цифрових валют. Проаналізовано структуру загальних міжнародних резервів центральних банків, на основі чого зроблено висновок про повільну динаміку змін в цій структурі. Однак тенденція до скорочення обсягів долару в міжнародних резервах має місце. Також проаналізовано структуру міжнародних валютних резервів Національного банку України. На основі даного аналізу проілюстровано, що у резервах НБУ переважає американський долар, частка інших резервних валют, крім євро, має тенденцію до зниження. Також встановлено, що у структурі міжнародних резервів НБУ основне місце належить цінним паперам, які є дохідним та ліквідним інструментом хоча й мають певний рівень ризикованості, пов’язаний з мінливістю процентних ставок.

Оподаткування – одне з першочергових питань внутрішньої політики будь-якої держави. Будь-яка адміністрація в розвинутих країнах має постійний пріоритет удосконалення податкової системи. Саме ця розбіжність у попиті на підвищення податкових зборів і попиті на створення сприятливих умов для вітчизняного підприємництва стає основною причиною змін у податковому законодавстві. Будь-де і будь-де, незалежно від обраної моделі економічного розвитку, оподаткування є обов’язковою частиною фінансової системи. Проблема в тому, що податок – складна категорія. Беручи до уваги податкові категорії в Україні, можна зробити висновок, що їх важко відокремити від складу відрахувань в інших країнах. Тому важливо визначити їх основні функції, принципи, елементи та процеси впливу на формування державної бюджетної політики. На сучасному етапі розвитку національної економіки її важлива позиція в довгостроковому ефективному зростанні залежить від якості управління в національній та місцевій фіскальних сферах. Як основний фінансовий план в Україні сьогодні державний бюджет є важливим механізмом перерозподілу фінансових ресурсів, забезпечення безперебійного функціонування національної економічної системи з одного боку та належного рівня соціальної безпеки з іншого. Важливого значення набуває ефективність дохідної складової державного бюджету з урахуванням поточних зовнішніх і внутрішніх негативних впливів (економічних і політичних). Враховуючи, що більшу частину доходів бюджету складають податкові надходження, аналіз цих тенденцій зумовлює актуальність теми наукового дослідження. Метою дослідження є визначення принципів оподаткування, їх характеристика та висвітлення основоположних принципів і засад податкової системи України. Методи дослідження. Для вирішення поставлених у роботі завдань на науковому рівні були використані такі методи дослідження: історичний (при вивченні історії становлення оподаткування прибутку підприємств); порівняльний аналіз (при вивченні економічних категорій, порядку оподаткування прибутку); статистичні та економічні методи (при вивченні тенденцій розвитку оподаткування, факторів, що впливають на розмір податкових надходжень). Результати дослідження. У статті дуже чітко визначено природу корпоративних податків та їх основні переваги та недоліки. Автор подав класичні підходи до сутності принципів оподаткування та додав свій, доповнивши його принципами ліквідності, платоспроможності, фінансової стійкості та принципом розширеного відтворення. Обґрунтовую доцільність виділення інвестиційної функції прямих податків з підприємств. Оригінальність дослідження. Запропоновано новий підхід до класифікації принципів оподаткування, що включає принципи ліквідності, платоспроможності та фінансової стійкості. Це дозволяє більш комплексно оцінювати вплив податкової системи на фінансовий стан підприємств та економіку в цілому.

Published: December 2024

Мета дослідження полягає у вивченні інституційного забезпечення державної політики у сфері запобігання та протидії корупції в Україні, а також аналіз ефективності функціонування відповідних органів та механізмів на основі сучасного досвіду. Методи дослідження. У процесі дослідження інституційного забезпечення державної політики у сфері запобігання та протидії корупції в Україні були використані такі наукові методи: аналіз нормативно-правових актів (застосовувався для вивчення правової бази, що регулює діяльність антикорупційних органів); порівняльний метод (використовувався для зіставлення діяльності окремих інституцій та порівняння їх завдань і повноважень); системний аналіз (застосовувався для комплексного вивчення особливостей реалізації антикорупційної політики як єдиної системи і взаємодії інституцій в ній). Використання цих методів дозволило здійснити комплексний аналіз інституційної бази державної антикорупційної політики та сформулювати практичні рекомендації щодо її вдосконалення. Результати. Інституційне забезпечення формування дієвої державної політики у сфері запобігання та протидії корупції є ключовим напрямом організаційно-правового забезпечення антикорупційної діяльності та сприяє формуванню європейської моделі публічного управління в Україні. В статті розглянуто функції та особливості діяльності державних органів, відповідальних за боротьбу з корупційними правопорушеннями та впровадження антикорупційної політики. Визначено невирішені питання щодо функціонування цих органів та представлено пропозиції щодо покращення ситуації у досліджуваній сфері. Підсумовано, що для досягнення більш ефективної протидії корупції в Україні необхідно впроваджувати низку реформ, спрямованих на зміцнення координації між антикорупційними органами, забезпечення їхньої незалежності, підвищення прозорості та довіри громадськості. Цінність дослідження полягає в обґрунтуванні рекомендацій для вдосконалення державної політики у сфері запобігання та протидії корупції в Україні, спрямованих на зміцнення інституційної бази, підвищення ефективності та прозорості у сфері боротьби з корупцією, а також на створення умов для довготривалого зменшення рівня корупції в Україні.
МІЖНАРОДНА ЕКОНОМІЧНА ДІЯЛЬНІСТЬ УКРАЇНИ Й ДЕРЖАВНА ПОЛІТИКА ЗАБЕЗПЕЧЕННЯ РИНКУ РИБОГОСПОДАРСЬКОГО ОБЛАДНАННЯ В АСПЕКТІ ЕКОНОМІЧНОЇ БЕЗПЕКИ МАШИНОБУДІВНОГО КОМПЛЕКСУ

У статті розглянуто базові підходи до розробки механізмів регулювання та пошуку шляхів здійснення державної політики та забезпечення галузі рибного господарства унікальним обладнанням в рамках підтримання економічної безпеки машинобудівного комплексу країни. Зосереджено увагу на рівні валового внутрішнього продукту, частці експорту продукції машинобудівного комплексу, динаміку імпорту й експорту комплектуючих та обладнання, а також необхідні обсяги інвестицій у галузь. Обґрунтовано, що зниження частки машинобудування у структурі промисловості підкреслює необхідність розробки цілеспрямованих державних заходів для підтримки галузі, яка є базовою складовою економічної безпеки. Досліджено, що сьогодні потрібно акцентувати увагу на виробництві унікального обладнання для специфічних галузей національної економіки, включаючи рибне господарства України. Вказане пов’язано з тим, що згідно з даними досліджень Продовольчої та сільськогосподарської організації ФАО ООН стрімке зменшення обсягів виробництва аквакультури пов’язані з наслідками воєнних дій в Україні. Розрахована загальна сума фінансової підтримки на наступні роки на обладнання для рибного господарства. Зроблено висновок, що у випадку, коли часткова компенсація витрат пошириться на обладнання для рибної галузі, виготовлене в Україні, це стимулюватиме попит на продукцію вітчизняного машинобудівного комплексу.
The Hidden Geography of Everyday Life
Authors: Coppack Philip
Published: December 2024

The book is a peculiar one, dealing as it does with the environments (in the broadest sense) that surround us, act upon us, and shape out decision-making. It considers our lived environments at all scales, from the rooms we inhabit to the neighborhoods, cities, regions, nations, and eventually the world in which we live. For the most part it deals with spatial scales up to and including the city. Its peculiarity stems from the perspective it takes, which is that there is no such thing as a shared objective environmental reality in which we live. Perception and cognition play such a dominant role in human behaviour that what we see as our urban world necessarily differs for everyone depending on their learned concepts and constructs, their intellectual level, and their cultural, social, economic, and biological context. The book ranges widely across disciplines as it attempts to explain just how it is that we humans, or at least our brains, create the urban world we take for granted and how the environments that comprise it change and evolve and morph across our lives. To do this it uses what we know from physics, biology, chemistry, and their various sub-disciplines: neuroscience, biochemistry, perception, and cognition. The hope is that in illustrating just how our remarkable brains do it, we can illuminate some the unknowns about the environments we shape, yet take for granted. 
Simulation of Voltage and Frequency Stabilization in PV-Based Microgrids Using Virtual Synchronous Generator Control
Authors: Zaw Tway Oo
Published: December 2024

In recent years, distributed generation technologies and micro-grids have garnered increasing attention, particularly with the rapid growth of renewable energy sources (RESs) integrated via power electronic converters. As the penetration of RESs in modern power systems rises, voltage and frequency support, traditionally provided by synchronous generators, can be effectively managed by Virtual Synchronous Generator (VSG) control. This paper presents the modeling and analysis of voltage and frequency stability enhancement in a PV-based micro-grid system using VSG control. The micro-grid system under study operates at 400V, 50Hz, and is integrated with a 0.4kV power distribution line. Mathematical models of the VSG control strategy are developed in MATLAB/Simulink. Simulation results demonstrate that VSG control significantly improves the voltage and frequency stability of the PV-based micro-grid system.
