Sheep farming is the main livestock industry in many countries. Further sheep farming growth in order to the population with cheap food products fully satisfying on the industry processes comprehensive mechanization basis, taking into account the sheep and pastures’ specific conditions should be carried out. There in sheep keeping technology, the most responsible and time consuming process is sheep shearing. The sheep shearing machine development’s history was mainly along the shearing machine design improving. However, even a completely perfect shearing machine is not able the labor productivity increase overall problem solving. Sheep shearing machine use by shearers’ working is greatly facilitated. Stationary and mobile shearing stations to carry out sheep mechanized shearing are used. A specific analysis of these points, as well as comments on each of them is given. Due to the sheep farms reorganization there in many parts of the country, this industry’s economic analysis suggests that there need sheep mass shearing at mobile shearing stations organizing. This is especially desirable for desert pastures’ conditions, as sheep throughout the year here are kept. A brief analysis of four mobile shearing stations (units) sets’ designs developed in Turkmenistan and Russia makes it possible to note that all of them with the necessary equipment for shearing sheep at the highest level are equipped. All shearing stations in production conditions had been tested and for production are recommended. For further research in this area, it is necessary mobile shearing stations (several copies) producing in order to them improving and in sheep breeding in various zones applying.

There on large livestock farms a nonbedding method of animals’ keeping is common. At such animals’ keeping, liquid and semiliquid manure is obtained. Such manure during storage into three fractions - upper, liquid and lower is stratified. The upper fraction surface contacts with the environment and therefore dries out and forms a crust. This manure heavier part, under the influence of gravity, settles to the manure storage’s bottom, forming a dense layer during prolonged storage. Thus, there in storage manure mass three fractions of different physical-and-mechanical properties are formed, for each of them extraction the different methods are used, by the corresponding machines implementing. As a result, the metal and energy consumption at manure extracting process by the manure storage is increased, and consequently, so as the agricultural products’ cost. The stored manure technological operation’s extracting can be reduced to an energy minimum by a homogeneous mass forming. This can be solved by the farm manure coming into the manure storage facility mixing. This operation can be implemented by the layers’ active movement by hydraulic or mechanical methods organizing. The hydraulic method only if liquid fractions without mechanical impurities presence at the pump entering by the impeller as working organ for they disable it at acting The most widespread mechanical method of manure fractions movement by a propeller agitator, forming a directional flow during rotation is carried out. These theoretical studies results concerning the liquid manure jet movement formed as a result the mixer agitator action in the medium of manure mass stored in a manure storage facility are presented. The relationship between the length of movement of the liquid manure jet, the angle of elevation of the blade’s helical line, this mixer diameter, its angular velocity and the mixer’s inclination in the relative to the horizontal plane has been established.
El dilema de la industrialización en chile
Authors: Méndez Briones Luis
Published: July 2024

Las medidas de política económica que echaron las bases de lo que fue el modelo de Industrialización Sustitutiva de Importaciones (ISI) comenzaron a aplicarse en Chile durante el primer gobierno de Carlos Ibañez del Campo (1927-1931) y se consolidaron a partir del gobierno de Pedro Aguirre Cerda (1938-1941) con la creación de la Corporación de Fomento de la Producción (CORFO) en el año 1939.
El elemento base de la estrategia estuvo en la aplicación de una barrera arancelaria destinada a proteger a la industria nacional, fomentando la producción nacional y haciéndola más competitiva frente a los bienes manufacturados de origen extranjero. En sus inicios la experiencia fue exitosa pues los estragos de la Primera Guerra Mundial, la Gran Depresión y la Segunda Guerra Mundial le otorgaron un entorno internacional favorable. Ello permitió que el Estado impulsara la creación de la industria eléctrica, de acero, de petróleos, la industria del azúcar nacional, el fomento pesquero y turístico, el apoyo a la pequeña minería, entre otros proyectos.

Вознесенская церковь в Твери: история и градоформирующее значение памятника
Authors: Салимов Алексей , Салимова Марина
Published: July 2024

В статье представлены результаты исследования истории и градоформирующей роли памятника XVIII века – Вознесенской церкви, расположенной в центре на главной улице Твери (Советской). После уничтожения в 1930-е годы ряда культовых зданий остался лишь один храм – Вознесенская церковь. Именно это сооружение в предвоенные годы стало основным градообразующим элементом в центральной части столицы Верхневолжья, но следует отметить его значимую градоформирующую роль ещё в дореволюционный период. Архитектурная история Вознесенского храма началась в первой половине 1830-х годов, когда на этом участке располагался небольшой посадский каменный храм. Возведённый в 1749–1751 годы, скорее всего, он был разобран во второй половине 1760-х годов во время градостроительного реформирования города на основе «регулярных» планировочных решений. Его местоположение в структуре «дорегулярной» застройки удачно совпало с новыми градостроительными тенденциями. Восстановленное после пожара 1763 года здание церкви ещё на несколько десятилетий сохранило архитектурный облик постройки елизаветинской эпохи. Однако присутствие в самом центре Твери небольшого по масштабам храма со временем вступило в противоречие не только с потребностями прихода, но и с градостроительной целесообразностью, поэтому в первой половине 1830-х годов «малоразмерную» барочную постройку сменило масштабное классицистическое сооружение.

Authors: Василенко Андрей
Published: July 2024

В статье впервые выявлена и прослежена цепь событий, определивших процесс выбора территории для размещения квартала Императорской Академии художеств в Санкт-Петербурге. Определены причинно-следственные связи между известными и вновь вводимыми в научный оборот событиями, касающимися выбора места для размещения Академии художеств. Выявлено, что формирование идеи о размещении Академии в России являлось единым процессом, длившимся более пятидесяти лет. Установлено, что корни этого процесса восходят к реформам Петра Великого и к градостроительным проектам Санкт-Петербурга Ж.Б. Леблона и Д.А. Трезини. Рассмотрены причины, по которым были отвергнуты альтернативные варианты размещения Императорской Академии художеств в древней столице – Москве, и даже на Дворцовой набережной у самого Зимнего дворца и почему И.И. Шувалов остановил выбор размещения на участке на набережной Васильевского острова.

Authors: Лавров Леонид , Молоткова Елена
Published: July 2024

На примере Санкт-Петербурга рассматриваются закономерности управляемого формирования и развития градостроительной структуры. Методической базой исследования является существующее представление о поэтапном характере освоения территории. Развитие градостроительной системы прослеживается по взаимодействию двух определяющих элементов – каркаса и ткани. Каркас – система главных транспортных путей, коммуникационных узлов и связанных с ними сооружений городского значения. Его инфраструктура преобразуется с учётом исторического контекста, но сохраняется системообразующее значение (в этом исследовании используют принятую в настоящее время классификацию городских улиц и дорог по их функциональной роли1 и распространяют ее на водные транспортные пути).Фиксируются очаговый характер городской ткани, возникавшей на начальной фазе освоения природного транспортного каркаса, функциональная и пространственная локализация поселений. Особое внимание уделяется радикальным преобразованиям второй половины XVIII века, когда внеуличные водные пути были дополнены сетью регулярных городских дорог, обеспечивших переход на новые формы землепользования.

On the Rule of Law of the State's Obligation to Supply for the Basic Medical Security Right in China
Authors: Gong Chenhang ,   Journal of Law research
Published: July 2024

The implementation of the “Healthy China Strategy” is an important part of the current national basic strategy. Health is also related to the basic survival and development of citizens. The right to health is an important fundamental right of citizens, and the basic medical security right is an important part of it. The basic medical security right is the right to guarantee citizens' basic access to medical care and the right to basic medical services, and is closely related to the right to life, the right to health and the right to social security. The State's obligation to supply for the basic medical security right mainly consists of the material supply obligation and the procedural supply obligation: the material supply obligation may be specific to the supply of medical insurance, medical assistance and medical facilities; and the procedural supply obligation consists of the supply of medical service and medical relief. The State's obligation to supply for the basic medical security right in practice in China mainly faces such practical problems as inadequate legal norms and low hierarchy of legislation, large differences in supply among regions, and low level of supply.
In this context, the State's obligation to supply for the basic medical security right should be further improved by, among other things, establishing the legal system of supply governed by the Constitution, formulating scientific supply standards, and developing diversified relief channels. At the same time, in terms of the leading and consistent internal logic, change the logic of legislative thinking from emphasizing the medical security administration in “drafts for comments” to the structured and typified basic medical insurance legal relations, establishing the system of medical security law, and thus promote the rule of law of the basic medical security right.

Published: July 2024

This paper provides a comprehensive overview of Australian drug laws, highlighting the evolution of laws from the late 19th century to the present, and comparing them with South Korean drug policies. It begins by exploring the historical context of Australian drug laws, highlighting the shift from minimal intervention in the late 19th century, characterized by the widespread use of drugs like opium and morphine, to more stringent drug control policies in the early 20th century. This change was influenced by international developments and domestic concerns, notably racial prejudices and the rise of international drug conventions.
The paper then delves into the legal frameworks governing drug offences in Australia, explaining the interplay of federal and state laws. It outlines the specific provisions and penalties, with an emphasis on the Criminal Code Act 1995(Cth) and the definitions of serious drugs. A detailed examination of drug offences under Federal law is provided, including distribution, production, import-export and possession offences, along with their respective penalties.
Furthermore, the paper discusses the enforcement and prosecution of drug laws in Australia, detailing the roles of law enforcement agencies, the prosecution process, and the judiciary's role in interpreting and applying these laws. It also highlights the shift in Australian drug policy towards harm reduction and public health approaches. This section includes case studies of harm reduction initiatives in Australia.
A notable aspect of the paper is the comparison between Australian and South Korean drug laws, elucidating their similarities and differences. While both countries adopt a strict stance on illicit drugs and have similar drug classification systems, they differ in their approach to personal use and possession, harm reduction focus, legal status of cannabis, and cultural perceptions of drug use.
The paper concludes by emphasizing the complexity of drug legislation and policy in Australia, shaped by international conventions and domestic priorities. It notes that Australian drug laws strike a balance between prohibition, control, and public health, providing valuable insights for international audiences. The paper also recognizes the dynamic nature of Australian drug law, suggesting that its evolution could significantly influence global drug policy, especially with emerging challenges like synthetic drugs and online drug trafficking.

Published: July 2024

Este estudo, o primeiro do seu tipo no Brasil, investiga a aplicação da Robotic Process Automation (RPA) no campo da contabilidade. Utilizando uma Revisão Sistemática da Literatura (RSL), foram coletados e analisados dados da base Scopus com o auxílio do software R Studio e do pacote Bibliometrix. O objetivo é discernir o impacto das intervenções de RPA sobre as organizações, colaboradores, executivos e clientes, com particular atenção a uma matriz conceitual que sublinha a necessidade premente de atualização curricular para os contabilistas. Os resultados sugerem que as grandes empresas conseguem automatizar processos mais facilmente, enquanto as pequenas e médias empresas encontram obstáculos significativos para a adoção da tecnologia, destacando a falta de suporte técnico para a transformação digital. De forma notável, a RPA não apenas realoca profissionais para funções mais estratégicas, mas também promove a integração de novas tecnologias nos currículos de formação, sinalizando direções para investigações futuras sobre os benefícios econômicos da implementação de RPA. Este artigo contribui para a teoria, ao evidenciar lacunas educacionais que necessitam de atenção imediata, e para o contexto social, ao incentivar o debate sobre o papel da digitalização na educação contábil.

Developments in low-cost techniques for growing high-quality nickel oxide thin films (NiOTFs) are critical enablers for the fabrication of NiO-based devices, particularly solar cells, light-emitting diodes, lasers, and many other applications. In this study, it has been demonstrated that the optical, electrical, and structural characteristics of NiOTFs coated on glass substrate employing a low-cost solution method are strongly influenced by post-thermal annealing treatments in ambient air. A comprehensive study was carried out on the characteristics of the deposited NiOTFs. X-ray diffraction (XRD) measurements indicate the enhancement of the crystal quality of films after annealing. There is a noticeable change and improvement in coated NiOTFs with heat treatment at 300 and 600 ℃ due to clear shifts in density. During the heating temperature increment, the energy of the band gap was shifted from 3.63 to 3.44 eV, and the electrical resistance of the NiOTFs varied from 1020 to 700 Ω-cm. Furthermore, the results indicate that the low-cost sol-gel (SG) deposition technique has a greater potential for producing high-quality p-type NiOTFs with minimal defects for electronic device applications.

This research aimed to evaluate the performance of dyes extracted from Acacia Nilotica bark on Tencel fabric dyeing. The extraction of dye was optimized by extracting dyes with different liquor ratios. The dyeing parameters were optimized under pH values from 5 to 14. The effect of different mordants was also observed to see the shades this dye can produce on Tencel fabric. The optimum dye extraction conditions for material-to-liquor ratio were found to be 1:10. The optimum pH was found to be 12. The color yield and fastness characteristics of the dyed materials were measured to assess them. It was determined that the addition of mordants affected the color values; as a result, distinct fashion hues were produced from the same dye extract by employing various mordants. This basic study of dyeing and extracting natural dye showed that this dye has the potential to be used for cellulosic fibers.

Authors: Wychowaniec Wojciech
Published: July 2024

The goal of this article is to analyse the main threats and benefits that accompany the implementation of age management policy, a method that enables workers aged 45+ to be highly effective. The article presents a demographic prognosis on the changing structure of human capital in the labour market, which determines the growing importance of age management in enterprises. The text contains an analysis of the key threats arising from a lack of employer action on age management, and the benefits that may be gained from age management policy. The article also examined the inevitability of changes, which will appear in the age structure of Polish people in the labour market and in companies. These particular changes will determinate plenty of consequences, mostly for employers, because the new personnel will require a slightly different management approach. My intention is to adapt the work to the requirements of the scientific community, as well as to the needs of labour market experts and business practitioners. This is why the paradigm of radical humanism was chosen for the article.

Intergenerational private transfers in the system of factors of population’s migration activity
Authors: Ryndzak Olha
Published: July 2024

The paper develops certain theoretical and methodological foundations of the research of intergenerational private transfers. In particular, it provides extended and more complex classification of transfers, dividing transfers into instrumental and socio-humanitarian and outlining the content details for each group. Moreover, not only positive (e.g. money, material assets), but also negative transfers (e.g. debts) that can be transmitted from one generation to the other are suggested to be taken into account. The author has developed the scheme of possible impact of material and instrumental transfers on the acceptors, their situation and migration activities, which shows the ambiguity of such links. Conducting of representative sociological surveys will contribute to more distinct establishment of dominating impact of intergenerational private transfers on migration activity of population.

The distribution of patients and practice patterns in pediatric dentistry are constantly changing. This study aimed to analyze the changing trends of patient distribution and treatment patterns in pediatric dentistry.Patient distribution and practice patterns from 2011 to 2020 at the Department of Pediatric Dentistry at Chonnam National University Dental Hospital were collected and reviewed. The total number of outpatients showed a tendency to increase until 2019; however, this value decreased slightly in 2020 owing to the impact of the coronavirus disease pandemic. From 2011 to 2020, the proportion of new patients decreased from 12.18% to 8.98%. In 2011, restorative treatment was the most common, followed by preventive, surgical, endodontic, and orthodontic treatments. After 2012, preventive treatment showed the highest proportion, follwed by restorative, surgical, orthodontic, and endodontic treatments in 2020. The frequency of sedation and the proportion of insured treatments tended to increase over the 10-year study periods.

Occlusal appliance therapy for temporomandibular disorders
Authors: Kang Jin-Kyu
Published: July 2024

Occlusal appliance is a removable device which fits over the occlusal surfaces of the teeth in one arch, devised to provide precise occlusal contact with the opposing teeth. Occlusal appliance is usually made of hard acrylic resin and allows optimum dentition in which condyle may assume in its most orthopedically stable position. Oc-clusal appliance is used to treat various kinds of temporomandibular disorders, including joint and muscle pain, disc derangements, parafunctional habits like bruxism and clenching, and degenerative joint diseases of TMJ.There are various types of occlusal appliances, but stabilization appliance and anterior positioning appliance are most frequently used. Stabilization appliance is fabricated to provide optimum occlusal relationship for the patient. This appliance is indicated for muscle and joint pain disorders and helpful for reducing parafunctional habits like bruxism. Anterior positioning appliance is designed to protrude mandible to a position that is more anterior than the intercuspal position. It is primarily used to treat disc displacement with reduction, intermittent lock and joint noises but some inflammatory disorders including retrodiscitis can be managed with this appli-ance. Occlusal appliance therapy is a successful treatment in reducing symptoms, and many previous reports indi-cates that its success rate is 70-90%. However, controversy exists over the exact mechanism by which occlusal appliance reduce symptoms. Occlusal appliance therapy is reversible, non-invasive therapy and effective therapeutic modalities for tem-poromandibular disorders. For the successful outcome, careful selection of the patient is needed. Also, it should be monitored regularly for the improvement of the disorder and the occurrence of side effects.

This study was conducted to determine demand of the dental staffs according to the size of the dental institutions. A survey was conducted through Google Survey, and 2,223 respondents(the member of the Korean Dental Association) were the final subjects of the study. The independent variable was the size of the dental institution set by the number of dental chairs, and the dependent variable was the difficulty in the recruitment of dental staffs, the time required to recruit, and tasks requiring additional staff. As a result of the study, there was a significant difference in the difficulty in the recruitment of dental staffs and the need of task by size of dental institution. The average difficulty in the recruitment of dental hygienists was 8.49, and 4 to 5 dental unit chairs scored the highest at 8.76. The average difficulty in the recruitment of auxiliary nurse was 6.48, and 1 to 3 dental unit chairs scored the highest at 6.83. For tasks requiring additional workers, the removal of calculus(scaling) and surgical assistance were the highest in all-scale institution. The need for suction and treatment preparation was relatively high in small-scale dental institution, and the need for dental impression and preventive hygiene was high in large-scale dental institution. In conclusion, it is necessary to approach the resolution of the dental staff recruitment difficulties differ-ently depending on the institutions's scale. It is suggested for small dental institution the regular training of dental assistants to assist in chair-side treatment, and for larger dental institution, it is suggested a policy to utilize existing dental hygienists.

Preservation of natural teeth and their structure is critical for chewing, swallowing, and better speech. Dentin and dental tissues are crucial in maintaining natural teeth and their structure, but treatment of dental tissue and dentin fracture is chal-lenging for dentistry. Hence, scientific understanding needs to be translated to discover novel dental treatments. Dental pulp stem cells (DPSCs) are mesenchymal stem cells (MSCs) isolated from the third molar pulp. These cells have similar characteristics to MSCs with a unique property where DPSCs can differentiate into dentin forming odontoblast-like cells. Here, we made an effort to evaluate the potential substrate that induces odontoblastic differentiation of DPSCs. In this study, JD005, a modified A2A antagonist from ZM-241385, was determined to enhance OD. Specifically, JD005 treatment signifi-cantly enhanced the OD markers like alkaline phosphatase (ALP), runt-related transcription factor 2 (RUNX2), OPN, dentin sialophosphoprotein (DSPP), and dentin matrix protein 1 (DMP1). Additionally, the DPSCs treated with JD005 showed enhanced SMAD phosphorylation associated with differentiation. These observations distinctively suggest that JD005 po-tentially contributes to dentin regeneration via odontoblast differentiation.

The purpose of this retrospective study was to evaluate the pharyngeal airway width according to the vertical facial type in Korean children in the developmental stage. In total, 101 participants aged 7 - 11 years were selected and divided into three groups based on the mandibular plane angle. The size of pharyngeal airway width was assessed using lateral cephalograms. The data were statistically analyzed using one way ANOVA test and independent t-test.The vertical growth group showed significantly narrower nasopharyngeal and upper oropharyngeal airway width than that in the normal and horizontal growth groups. Lower nasopharyngeal airway width was the widest in the horizontal growth group and the difference was statistically significant. The vertical oropharyngeal airway space was significantly smaller in girls when compared to boys, and no distinct difference was observed between horizontal airway width of the sexes. The results from this study indicate that patients with vertical facial growth pattern had less pharyngeal airway width than the patients with normal and horizontal facial growth patterns.
