Published: December 2024

The OBJECTIVE was to evaluate the immediate and long-term results of integral suture application and to determine the indications for its use in eTEP hernioplasty for primary rectal inguinal hernia in men.METHODS AND MATERIALS. A prospective single-center double-blind randomized controlled study on the basis of the City Clinical Hospital named after S. S. Yudin was conducted. The study included patients with the first-diagnosed direct inguinal hernias for eTEP hernioplasty with hernia gate size from 1.5 cm to 3 cm corresponding to MP2 according to EHS (2009). Patients were allocated to a comparison group with hernia defect closure and a control group using the ALEA randomization program. The following parameters were evaluated in patients: the presence of seroma on the 1st day after laparoscopic hernioplasty according to the ultrasound results, the dynamics of seroma volume, the degree of pain syndrome according to the visual analog scale (VAS), the duration of surgical intervention, 30-day adverse events, as well as the patients’ quality of life according to the Likert scale.RESULTS. A total of 142 patients were included (n1=71; n2=71). There were no significant differences in baseline characteristics between the two groups. Suturing the hernia defect using the integral suture technique was associated with less development of postoperative seromas ∆p=0.32 (95 % confidence interval [CI] 0.14–0.5, p=0.05). There were no statistical differences in pain and quality of life among patients. No 30-day adverse events were observed in the two groups. A statistically significant increase in the duration of the operation when using the integral suture was revealed, but not more than 7 minutes.CONCLUSION. Since anatomical justification has made laparoscopic hernioplasty a safer operation, we believe that endoscopic suturing of rectal inguinal hernia defect larger than 2.5 cm (P=0.052) with the use of integral suture in the MP2 group according to EHS is associated with a lower incidence of seroma development, low risk of recurrence, absence of significant pain syndrome after suturing.
Comparison of valve-sparing techniques for surgical treatment of aortic root pathology: Florida Sleeve vs David procedure
Authors: Efendiev V. U. , Noginov V. K.
Published: December 2024

INTRODUCTION. Such reconstructive operations on the aortic root as the David and Florida Sleeve procedures are fundamentally different in prosthetics of the aortic root with reimplantation of the ostiums of the coronary arteries into the prosthesis during David surgery and preservation of all native structures of the aortic root without reimplantation of the ostiums of the coronary arteries during Florida Sleeve surgery. Both procedures effectively reduce the dilated aortic ring, however, the Florida Sleeve procedure is performed much less frequently than the David procedure.The OBJECTIVE was to study and analyze literature sources that present a comparison of the results of valve-preserving Florida Sleeve and David procedures.METHODS AND MATERIALS. A search was conducted in PubMed and e-library databases from 2005 to 12.06.2023 for search queries. The studies were selected according to the PRISMA algorithm.RESULTS. According to the results of search queries, 18 articles were found, 2 articles satisfying the selection criteria were included in the analysis. The meta-analysis was not carried out due to the pronounced heterogeneity of the data. In both studies, a statistically significant shorter time of cardiopulmonary bypass and aortic occlusion takes when performing Florida Sleeve compared to David procedure. Short-term and long-term 5-year results of operations did not show statistically significant difference.

Authors: Roelofsen Mathijs
Published: December 2024

À l’instar de ses voisines, la cité de Fribourg mobilisait sa population masculine pour défendre ses murs et partir en guerre. Les documents militaires d’une grande richesse conservés aux Archives de l’État de Fribourg permettent de saisir les aspects fonctionnels de l’organisation militaire de la ville entre 1350 et 1550. En recoupant ces pièces avec des sources administratives et comptables, ce livre propose une analyse quantitative et sérielle qui met en lumière l’influence de la situation économique des acteurs dans la possession d’équipement militaire, l’adaptation du système de recrutement des troupes à l’expansion du territoire fribourgeois et l’affirmation des capacités militaires de la ville à travers l’accroissement du parc municipal d’armes. L’enquête révèle ainsi la diversité des liens entre le système militaire et la société urbaine.
The Impacts of Housing Welfare Policy on the Labor Supply: Focusing on the Public Rental Housing Program and Housing Allowance Program
Authors:   Korean Association for Housing Policy Studies, Park Hyunjun , Jin Changha
Published: December 2024

This study examines the effect of Public Rental Housing Program and Housing Allowance Program on the labor market outcomes including labor participation and household wages. We hypothesize that both public rental housing and housing allowances significantly impact labor market outcome. Utilizing data from the Korea Welfare Panel Study (KWPS), the study adopts Propensity Score Matching(PSM)method to compare the labor supply elasticity between public and private rental households as well as between recipients and non-recipients of the housing allowance program. The results indicate that the public rental housing program has the insignificant effects on household labor market outcomes, while the housing allowance policy negatively affects the labor market outcomes. Thus the findings suggest a policy implication to design specific employment matching programs based on the Housing Allowance Program for households.

Authors:   Korean Association for Housing Policy Studies, Cho Ilhyun , Sung Bongsuk , Park ChunGun , Lee Sung-Jae , Kong Jiyoung
Published: December 2024

We study the factors of the residential PV installations at the household level in South Korea using the 2017 Energy Consumption Survey data, which investigates households with renewable energy systems for the first time in South Korea. Our study focuses on detached houses whose owners have applied for subsidy programs for residential PV installation. We employ a penalized logistic regression model to test the relationship between study variables. We find that PV is more likely to be installed in bigger and newer houses and outside the city. We also find that household income is significantly and positively associated with PV installations, which may lead to controversy regarding the subsidy program. Lastly, population aging and the increase in the number of single-person households, and the demographic phenomenon that South Korea is facing reduce the likelihood of PV adoption.
Analyzing the Announcement Effects of the First New Town Redevelopment on Apartment Property Values: Focusing on the Marginal Effects of House Building Age in Seongnam City
Authors:   Korean Association for Housing Policy Studies, Kim JaeHyeon , Woo Ayoung
Published: December 2024

Interest in redevelopment and reconstruction has been increasing due to the legislation regarding the Special Act for the 1st New Town and commitments to expanding housing supply by accelerating reconstruction. While there has been a lot of discussion on the spillover effects of housing supply from the reconstruction of the 1st New Town on the real estate market, there has been little empirical research on the effects of policy announcements made prior to the implementation of reconstruction projects. Therefore, this study examines the impact of public announcements regarding the 1st New Town redevelopments on apartment prices in Seongnam City, Gyeonggi-do. Based on the Ministry of Land’s apartment transaction price data, which includes 7,492 units, we use a Difference-in-Difference-in-Differences (DDD) model to clarify the causal effects of public announcements and a hedonic price model with an interaction term between building age and announcement periods to account for the marginal effects of building age over time. The results of this study can be used as a basis for urban planners and policymakers to formulate policies on the maintenance and support of the 1st New Town.

Analyzing the Strategic Value of Railways: Centered on the Russia-Ukraine War
Authors:   Institute for Russian and Altaic Studies, CBNU, Park Eun Kyung
Published: December 2024

This study analyzes the strategic role of railroads in modern warfare through the Russia-Ukraine war. Railways are essential resources for transporting military goods and maintaining economic activity, and act as an important factor in determining the victory or defeat of war. This study used a mixed research methodology combining quantitative data analysis and qualitative case analysis. Through this, the military and economic impact of the railway was evaluated, and the bombing of the Kramatorsk railway station and the explosion of the Crimean Bridge were considered in depth.
Technological advances have changed the strategic value of railroads, and the introduction of high-speed railways, automation systems, and advanced information and communication technologies has greatly improved the speed and efficiency of railroads. These developments are expanding the role of railroads in modern warfare. In addition, the importance of international cooperation is emphasized, and measures to increase the strategic value of railroads through railway connection and standardization between countries are needed.
The findings suggest the need for technology development to counter emerging threats such as drones and cyberattacks, and provide important implications for national security and economic policy establishment. Along with policy suggestions for building a sustainable rail system, technical research is proposed to strengthen the resilience and improve efficiency of the rail system as a future research direction. This research will contribute to enabling railroads to continue to strengthen their role as key infrastructure in modern warfare.
El teatro platónico del pensamiento
Authors: Cany Bruno
Published: December 2024

Es preciso volver a iniciar con esta distancia espectacular que existe entre la escritura de Platón y la lectura que hacemos de ella. Una diferencia tanto más espectacular, dado que durante mucho tiempo se ha considerado insignificante, desde un punto de vista filosófico, la extraordinaria calidad literaria de su obra.
Ahora bien, no es en absoluto insignificante, para cada una de sus propias filosofías, que Platón sea un maestro del dialogos o que Parménides sea un versificador (probablemente no tan mediocre como se suele afirmar). El hexámetro dactílico en el eleata y el diálogo teatral en el ateniense no pueden ocultarse sin que nuestra comprensión de sus filosofías se vea mermada.

Authors: Chadha Arzoo , Bakshi Rita
Published: December 2024

Objectives

The objective of this study is to evaluate and compare the efficacy of various sperm extraction techniques used in Assisted Reproductive Technology (ART), focusing on sperm retrieval rates, fertilization rates, and clinical outcomes in patients undergoing fertility treatments.

Material and Methods

This retrospective observational study was conducted at RISAA IVF, Green Park, New Delhi, from January 2023 to January 2024. The study included male participants diagnosed with azoospermia, who underwent ART procedures such as in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). Sperm extraction techniques evaluated include percutaneous epididymal sperm aspiration (PESA), testicular sperm aspiration (TESA), and microdissection testicular sperm extraction (micro-TESE). Data were collected from electronic medical records, laboratory reports, and patient charts, focusing on demographic data, sperm retrieval rates, and clinical outcomes. Statistical analysis was performed using SPSS software, with significance set at P < 0.05.

Results

Surgical sperm retrieval was performed on 11 azoospermic patients. Viable sperm was successfully retrieved using PESA in 18.1% of the patients, while TESA and micro-TESE yielded successful retrievals in 63.6% and 18.1% of the cases, respectively. The overall pregnancy rate achieved through these procedures was 63.6%. No significant difference in pregnancy rates was observed between the different sperm retrieval techniques (P > 0.05).

Conclusion

The study highlights that PESA, TESA, and micro-TESE are effective sperm extraction techniques for azoospermic patients undergoing ART. The success in sperm retrieval and subsequent pregnancy outcomes underscores the importance of selecting the appropriate method based on individual patient conditions. These findings contribute to the evidence base for optimizing fertility treatments in patients with severe male factor infertility.

Published: December 2024

Package boiler (PB) is a utility unit essential for producing steam by heating Boiler Feed Water (BFW) through the combustion of natural gas with air. Therefore, this study aimed to investigate the effect of heat loss on PB efficiency. To achieve this, direct and indirect methods were adopted, with data collected between 4 July and 29 August 2023. The results showed that PB efficiency in the fertilizer industry during this period ranged from 76.06% to 80.71%. On August 29, 2023, under optimal conditions, an efficiency of 80.71% was achieved, while a significant drop to 65.44% occurred during the 6th week on August 8, 2023, due to low oxygen (O2) levels. Flue gas analysis on August 29, 2023, obtained 3.64% excess O2, 11.17% carbon dioxide (CO2), and 0.04% carbon monoxide (CO). PB performance was influenced by heat loss from the dry flue gas, hydrogen (H2) content on flue gas, moisture in air and fuel, incomplete combustion, as well as radiation and convection phenomena.

Published: December 2024

В статье рассматривается образование в Чеченской автономной области в 1920-е гг. Проблема ликвидации отсталости «национальных окраин» предусматривала образование на родном языке. Известно, что в 20-х гг. ХХ в. количество религиозных школ в Чечне превышало число светских школ и преподавали там одни и те же учителя. Борьба с арабизацией образования заставила Наркомпрос Горской АССР вернуться к выработке новой графической основы, применимой к языкам северокавказских народов. В Чеченской автономной области подготовке местных кадров придавали большое значение, лучших выпускников новых советских школ направляли в различные вузы и на рабфаки. Показано, что при строительстве школьного образования в ЧАО остро стояли проблемы подготовки учительских кадров, нехватки учителей, помещений, оборудования, учебников, отсутствия одежды и обуви у учащихся. Обучать горцев грамоте на их родном языке было важно и потому, что предстоял перевод всего делопроизводства в национальных областях на местные языки. Развитие социалистического строительства и связанные с этим задачи по подготовке кадров требовали скорейшего проведения всеобщего обязательного начального обучения. Введение всеобуча было сопряжено со строительством новых школ, увеличением числа учителей и повышением их квалификации, значительными капиталовложениями.

The article examines education in the Chechen Autonomous Region in the 1920s. The problem of eliminating the backwardness of the "national outskirts" provided for education in the native language. It is known that in the 20s of the twentieth century, the number of religious schools in Chechnya exceeded the number of secular schools and the same teachers taught there. The struggle against the Arabization of education forced the People's Commissariat of Education of the Mountainous ASSR to return to the development of a new graphical framework applicable to the languages of the North Caucasian peoples. In the Chechen Autonomous Region, great importance was attached to the training of local personnel, and the best graduates of the new Soviet schools were sent to various universities and labor departments. It is shown that the training of teachers, the lack of teachers, premises, equipment, textbooks, and often students could not attend school due to lack of clothes and shoes were acute during the construction of school education in the CHAO. It was also important to teach the highlanders to read and write in their native language because all office work had to be translated into national languages
КУЛЬТ ВОДЫ У НАРОДОВ ДАГЕСТАНА: ОТРАЖЕНИЕ В ФОЛЬКЛОРЕ, РИТУАЛЬНО-ОБРЯДОВЫХ КОМПЛЕКСАХ И РЕЛИГИОЗНЫХ ВЕРОВАНИЯХ

Published: December 2024

Статья посвящена представлениям народов Дагестана о воде в XIX – начале XX в. Богарное земледелие, напрямую зависимое от осадков, на большей части территории Дагестана и, соответственно, повышенный спрос на воду в период выполнения сельскохозяйственных работ вынуждали жителей горного края рационально расходовать имеющиеся водные ресурсы, бережно относиться к источникам воды. Почитание стихии воды народами Дагестана переросло в ее обожествление и олицетворение в мифологическом образе Матери воды. Целью данной работы является показать сквозь призму фольклора, обрядовых действий и религиозных верований отношение народов Дагестана к воде. Для достижения поставленной цели использованы труды по этнографии Дагестана и полевой материал авторов. В рамках исследования рассмотрены различные фольклорные жанры, комплекс ритуально-обрядовых действий и религиозных верований, связанных с водой. Исследование показало, что почитание воды и возведение её в ранг культа превратило отдаленные водные источники в места поклонения и проведения молебных мероприятий о ниспослании дождя. Вера в целебные и очистительные силы воды помогала при родах, «снятии» сглаза, выполнении магических ритуалов, а страх перед водной стихией породил различные запреты и веру в существование демонических духов, связанных с водой. Статья является обобщающим исследованием, основанным на авторских полевых материалах и литературе по данной проблеме.

The article is devoted to the ideas of the peoples of Dagestan about water in the XIX – early XX century. Rain-fed agriculture, directly dependent on precipitation, in most of the territory of Dagestan and, accordingly, increased demand for water during the period of agricultural work, forced residents of the mountainous region to rationally use available water resources and take care of water sources. The veneration of the element of water by the peoples of Dagestan has grown into its deification and personification in the mythological image of the Mother of Water. The purpose of this work is to show through the prism of folklore, ritual actions and religious beliefs the attitude of the peoples of Dagestan to water. To achieve this goal, the works on the ethnography of Dagestan and the field material of the authors were used. The study examines various folklore genres, a complex of ritual and ceremonial actions and religious beliefs related to water. The study showed that the veneration of water and its elevation to the rank of a cult turned remote water sources into places of worship and prayer events for the sending of rain. Belief in the healing and purifying powers of water helped with childbirth, "removing" the evil eye, performing magical rituals, and fear of the water element gave rise to various prohibitions and belief in the existence of demonic spirits associated with water. The article is a generalizing study based on the author's field materials and literature on this issue.

Self-assembly of amphiphilic bottlebrush block copolymers (BCPs), which have backbones with two types of densely grafted side chains, is less well understood compared to their linear counterparts. Specifically, the solution self-assembly of tapered bottlebrush BCPs, which are approximately cone-shaped with specific cone directionality (hydrophilic or hydrophobic tips), remains unexplored. This work describes a series of 8 tapered and 4 cylindrical bottlebrush BCPs with varying ratios of hydrophobic polystyrene (PS) and hydrophilic poly(acrylic acid) (PAA) side chains, synthesized by the sequential addition of macromonomers ring-opening metathesis polymerization (SAM-ROMP) method. The nanostructures formed by these BCPs in water were evaluated using cryogenic transmission electron microscopy, small-angle neutron scattering, and dynamic light scattering. Results showed that most BCPs formed multiple types of nanostructures, all with surface protrusions, including spherical micelles, cylindrical micelles, and vesicles, with transitional structures between each, such as ellipsoids and semi-vesicles. Coarse-grained molecular dynamics simulations aided interpretation of the experimental data. Collectively, results revealed two distinct self-assembly pathways through which the BCPs evolved from micelles into complex nanostructures. One pathway involved micelle fusion, resulting in elliptical and cylindrical aggregates that in some cases fused further to form Y-junctions. The second pathway entailed micelle maturation into semivesicles, which subsequently formed vesicles and, at times, large compound vesicles. This study provides the first experimental evidence supporting vesicle formation via semivesicles in bottlebrush BCPs. Collectively, these findings highlight how structural parameters such as cone directionality influence self-assembly in these large, cone-shaped polymeric amphiphiles.
Neural Mulliken Analysis: Molecular Graphs from Density Matrices for QSPR on Raw Quantum-Chemical Data
Authors: Gromov Oleg
Published: December 2024

Since the introduction of Graph Neural Networks (GNNs), molecular graphs have become useful tools in chemical informatics. However, in property prediction tasks, graph embeddings often still resemble traditional fingerprints. Here, we propose a straightforward approach to provide modern GNNs with raw quantum-chemical data, enabling efficient solutions to a range of chemical machine-learning problems. The central role is played by the 1-electron density matrix derived from quantum chemical calculations (e.g. Hartree-Fock, DFT). The diagonal blocks of the density matrix are used as embeddings for the atomic nodes (“atoms”) in the molecular graph. Unlike conventional molecular graph representations, the chemical bond concept is not used. Instead, an additional set of nodes (“links”) between pairs of atoms is introduced. Their embeddings are the off-diagonal blocks of the density matrix, related to particular atom pairs. Directed graph edges connect either “atoms” with “links” or vice versa. The embeddings of the edges are derived from the basis set overlap matrix. The overlaps serve two purposes: first, they encode structural information such as distances and angles. Second, they act as weights in pooling operations. The use of element-wise multiplication of densities and overlaps is inspired by the Mulliken population analysis scheme. The proposed concept was further tested using the Solubility Challenge (2008) by Llinàs et al. (DOI: 10.1021/ci800058v). A GNN was trained on a small dataset comprising 94 aqueous solubilities of drug-like molecules and subsequently used to predict the aqueous solubilities of 28 test molecules. The model achieved an RM SE of 0.68 and an R 2 of 0.76, outperforming all methods proposed at that time. In our view, this represents a promising approach, particularly considering that even in a preliminary test the proposed architecture seems to be able to achieve state-of-the-art accuracy.

Symmetry is an important factor in material design. Generally, it is difficult to quantitively discuss symmetry-property relations. Two materials only with symmetry differences are requisite to verify whether polar or nonpolar chiral systems are advantageous for a specific property/phenomenon, such as chirality-induced spin selectivity. However, it is difficult to selectively prepare materials having different symmetries without changing other physical properties. The current study successfully prepared seven exceptionally similar crystals with different symmetries in terms of polarity, chirality, and enantiomer alignments, which affords ideal materials for the abovementioned studies. Furthermore, we revealed a universal guiding principle on the self-assembly pattern of bowl-shaped molecules to predict the resultant assembled structures with the help of molecular dynamics simulations.
Ecotourism and hunting in Ukraine: development analysis and forecast for the future
Authors: Portiannik Serhii , Merchanskyi Volodymyr
Published: December 2024

The development of ecological tourism is important for any country of the European Union, the USA, including Ukraine. An important component of ecotourism in different countries can be a combination of unique ecological, cultural and historical routes with the possibility of active recreation for tourists in the form of fishing or hunting, if there are suitable conditions for this. The territory of Ukrainian communities is rich in natural and cultural and historical objects. Unfortunately, Russian aggression led to the destruction of many unique natural landscapes, forest, hunting grounds, water ecosystems are bombed, not only people die, but also hunting (wild) animals, historical and cultural monuments are destroyed, such as the national literary and memorial the museum of the outstanding Ukrainian writer and philosopher Hryhoriy Savich Skovoroda in Kharkiv region. The aim and objectives of the research ¬ to analyze ecological and hunting tourism in Ukraine before the start of hostilities in the country and to assess the prospects for the development of the ecological tourism industry after the end of hostilities, in peacetime with the simultaneous stable and balanced development of hunting in natural territories that have not undergone ecocide taking into account positive and negative international experience, international norms, rules of environmental activity. The material for research was scientific works, publications of famous domestic and foreign scientists, monographs of others. Increased attention is paid to environmentally safe and economically efficient management of hunting and tourism in the countries of the European Union. In the conditions of the war, it is very difficult to develop ecological and hunting tourism and hunting economy, but in the post-war period, the country will have such opportunities. Today, it is necessary to analyze the state of industries, to take into account the international experience of effective management of natural resources, forest and hunting grounds in the process of reform. Ecological and hunting tourism should become not only economically efficient, but also such that ensures stable recovery, increase in the population of hunting animals, wider use of photo hunting, creation of an opportunity for recovery and psychological rehabilitation of hero warriors, defenders of the country after the war. Different regions of Ukraine have forest and hunting grounds to a greater or lesser extent. It will not be possible everywhere to combine the development of ecological tourism with the development of hunting, but where it can be done, the state should contribute, including by improving the regulatory and legal framework, support business, attract the help of international partners, promote the establishment of an attractive investment climate.

Safe drinking water is necessary for optimum health, but a sufficient supply of safe
drinking water is challenging in the twentieth century, particularly in highly populated
cities like Dhaka. Due to the lack of fresh natural resources of potable water and the
higher price of the commercially marketed mineral water bottle, many consumers prefer
relatively lower-cost jar drinking water. However, the physicochemical properties and the
safety of these jar-drinking waters are largely unknown. This study aimed to assess the
physicochemical characteristics and microbiological safety of jar drinking water marketed
in Dhaka City. Water samples from fifty different jar water sellers were collected and
examined for different chemical quality parameters and microbiological safety using
standard procedures and all test results were compared to water quality standards provided
by the World Health Organization (WHO) and Bangladesh Standard and Testing
Institution (BSTI). Heterotrophic plate count and coliform count were performed on
different agar media and biochemical experiments were performed for the characterization
of bacterial isolates. This research found that the total hardness, pH, total dissolved solids,
electrical conductivity, and chloride content of the majority of the water samples were
determined to be within acceptable limits. However, a large number of samples (88%)
were found to be above the acceptable range for calcium and magnesium hardness, and
approximately 33% of samples had greater levels of inorganic iron than the recommended
limit. A total of 34 (68%) out of 50 samples exceeded the safety limit of heterotrophic
bacteria whereas a total of 18 (36%) samples were found contaminated with coliform
bacteria (ranges 3 to 29 CFU/100 mL). Biochemical experiments revealed another
concerning fact, 14% of water samples were found positive for Escherichia coli and 6%
was Salmonella spp. The findings of the study showed that the majority of the jar drinking
water samples obtained throughout Dhaka City was not safe as per the standard provided
by the WHO and/or BSTI. Therefore, these jar drinking waters can be a source of
significant public health threat.

Pumpkin is a source of β-carotene, vitamins, flavonoids, saccharides, water-soluble
vitamins, mineral salts, and phenolics which are beneficial for health. Porang flour acts as
a thickener and stabilizer from glucomannan content. This study aimed to determine the
effect of adding porang flour on antioxidant activity, levels of β-carotene, levels of
vitamin C, total phenolic, and dietary fiber of instant pumpkin soup. The experimental
research method uses a one-factorial, completely randomized design (CRD) with five
treatments and five replications. The research phase began with the preparation of instant
pumpkin soup, with the addition of various variations of porang flour (0, 0.5, 1, 1.5 and
2%), then analysis was performed on antioxidant activity, levels of β-carotene, vitamin C,
total phenolic and crude fiber. The results showed that increasing the concentration of
porang flour caused an increase in antioxidant levels, total phenolic, crude fiber, also a
decrease in β-carotene and vitamin C levels of instant pumpkin soup. It was concluded
that adding 1.5% (w/w) porang flour produced instant pumpkin soup with the best
chemical properties.

Розглядаються три основні підходи до її вивчення: соціально-психологічний, етнопсихологічний та економіко-психологічний. Виокремлюються проблеми економічної соціалізації в умовах соціальної транзитивності. Підкреслюється, що дослідження економічної соціалізації мають вагомий фундаментальний потенціал, пов’язаний із тим, що цей вид соціалізації у згорнутому вигляді відображає різноманіття та суперечливість конструювання особистістю своїх відносин із соціумом. Із усіх видів соціалізації саме економічна найбільше пов’язана з актуальним станом соціуму. У загальному вигляді вона визначається як процес, у якому люди навчаються діяти в економіці: те, як вони плануватимуть бюджет, позичатимуть гроші, навчаються економити, купувати, сприймати рекламу, а також розуміти ширше призначення економіки. Економічну соціалізацію можна розглядати як процес становлення та розвитку економічної свідомості. Зазначається, що важливою характеристикою сучасного суспільства є його транзитивність, яка є відносно новим та неоднозначним для гуманітарного знання поняттям, що відображає високий динамізм сучасного життя, множинність та невизначеність будь-якої конкретної соціальної ситуації. Нині вплив транзитивності істотно зростає, торкаючись усіх сфер повсякденного життя. Нова ситуація транзитивності характерна для всіх поколінь, хоча, звісно, найбільш значущою стає для молоді та підлітків. Ситуація транзитивності пов’язана з кількома причинами: кризовим станом у сучасному світі, що виявився на межі зміни століть, зміною часу та простору організації товариств, появою нового технологічного та інформаційного простору. Процес економічної соціалізації у транзитивному суспільстві вимагає розгорнутого та всебічного вивчення. У сучасній ситуації у зв’язку з виникненням нового типу соціально-економічних відносин саме економічна соціалізація більшою мірою відображає усе різноманіття та суперечливість конструювання особистістю своїх відносин із соціумом.

Статтю присвячено вивченню професійних компетентностей персоналу девелоперських організацій. Досліджено професійну діяльність 175 осіб у період 2023–2024 рр. Методики дослідження: «Визначення діяльнісної ефективності організації», «Діагностика емоційного інтелекту», «Діагностика мотивації досягнень». Виокремлено три групи чинників впливу на ефективність діяльності організації у групі керівників (ГК) та фахівців (ГФ): розвиваючі – «продуктивні», що підвищують ефективність, у яких тип управління та відносини зрілі, демократичні; провокуючі – «утримуючі», що розбалансовують ефективність та в яких тип управління й відносини нераціональний, конфліктний; застрягаючі – «непродуктивні», що знижують ефективність та у яких тип управління та відносини незрілі, авторитарно руйнуючі. У групі керівників установлено зв’язок між показниками шкал «емоційна обізнаність» і «розпізнавання емоцій інших людей», що свідчить про якість і точність розпізнавання емоцій інших осіб. Також виявлено зв’язок шкал «самомотівація» та «управління власними емоціями», що свідчить про знижену здатність управляти своїми емоціями та зниження самомотивації. У групі фахівців виявлено зв’язок між шкалами «емоційна обізнаність» і «розпізнавання емоцій інших людей», що свідчило про знижену здатність виявляти та розпізнавати емоції інших людей. Також виявлений зв’язок між «емоційною обізнаністю» і «емпатією» свідчив про вплив низької емоційної обізнаності на зниження якісної емпатії з іншими людьми та низьку самомотівацію (p<0,05). ГК мала високий рівень стриманості в прояві емоцій, а респонденти ГФ краще розуміли та розпізнавали емоції інших людей, могли підтримувати власний емоційний стан за рахунок демонстрації своїх почуттів (p<0,05). Установлено, що емоційний інтелект є головним складником у досягненні успішної самореалізації досліджених ГК та ГФ, коли персонал розуміє свої емоції і застосовує їх конструктивним способом, що покращує його ерудованість та інтелектуальні здібності, допомагає особистісному розвитку, продуктивній взаємодії в організації та з бізнес-партнерами, клієнтами.
Kia Vai Rai Auraka Kia Taui‘ia - Let it remain, Let it change: Negotiations of religion among Cook Island Māori in New Zealand
Authors:   , Tairea Arama
Published: December 2024

This thesis examines how Cook Island Māori in contemporary New Zealand negotiate religion. It does so through a qualitative study, based on in-depth conversations with ten Cook Island Māori. The conversations reveal a complex social and relational dynamic to the ways in which Cook Island Māori understand and navigate religion. I argue that the Cook Island Māori in this research negotiate religion in a socialised manner that seeks to make sense of Christianity’s relationship with Cook Island Māori culture. To understand the ways in which this socialised negotiation of religion occurs, I employ the Cook Island Māori relational methodology, ‘akapapa‘anga, and draw from recent scholarship examining the discursive construction of religion. Through this approach, I identified three ‘modes of sociality’ which I name ‘Religion Affirmed,’ ‘Religion Redescribed,’ and ‘Religion Unsettled.’ Each mode captures the different and distinct ways in which these Cook Island Māori are negotiating what religion signifies for them, trying to make sense of Christianity’s relationship to Cook Island Māori culture, and navigating broader social obligations towards family and their community. Sitting underneath these socialised negotiations of religion is the impact of colonisation on Cook Island Māori people and culture. The impact of colonisation is contested due to implications to personal, social, and historical agency. This thesis demonstrates that the meaning of ‘religion,’ what constitutes Cook Island Māori culture, and the importance of different social relationships, are contested. It also indicates the centrality of ‘akapapa‘anga in the negotiation of these differences, the ongoing significance of Christianity in shaping diverse understandings of religion for Cook Island Māori, and the fruitfulness of relational epistemologies for the social scientific study of Pacific religion today.

Objective: In October 2018, the Government of Canada legalized cannabis for recreational use nationwide. The effects of legalization on cannabis use have been primarily assessed through cross-sectional surveys. Method: In the present study, a two-wave longitudinal design was used to explore potential demographic, substance use and behavioral addiction, and mental health predictors of change in cannabis use status following legalization. Canadian online panelists (18+) were initially surveyed about their gambling and substance use in 2018 (i.e., before cannabis legalization). From the original sample, 4,707 (46.2%) were retained in the follow-up survey one year later, post-cannabis legalization. These respondents were the focus of the present study. Results: When queried about how legalization would impact their use, 61.8% said, ‘I’ll never use it’, 21.1% stated ‘I’ll use it about the same as I do now’, 10.3% indicated ‘I may try it for the first time’, 5.0% answered ‘I’ll use it more’, and 1.9% responded that ‘I’ll use it less’. Consistent with these sentiments, within the retained sample there was a modest but significant increase in cannabis use from baseline (18.4%) to follow-up (26.1%). Regressions established that younger age, being male, substance use, tobacco or e-cigarette use, problematic gambling, and stated intention to use cannabis were predictors of later cannabis use. Conclusions: This national cohort design indicates that cannabis use appears to have increased in Canada following legalization. The present study makes a unique contribution by also identifying variables that statistically forecast movement toward and away from cannabis use.

The Kα and Kβ X-ray emission spectra of sulfur and phosphorus encapsulated within single-walled carbon nanotubes were measured using a laboratory X-ray spectrometer for the first time. The obtained spectra were compared with those of their bulk counterparts, namely, plastic sulfur and red phosphorus. Models of sulfur and phosphorus chains were constructed both in their free state and when encapsulated in nanotubes. Quantum chemical calculations were performed to analyze the distribution of the 3p electron density in the valence band. A strong correlation was observed between the positions of the theoretical bands and the shapes of the experimental Kβ spectra. By comparing the spectra of free and encapsulated sulfur and phosphorus, we analyzed their electronic interactions with the walls of carbon nanotubes. This analysis identified specific features in the electronic structure of models that contribute to the observed doping behavior in the nanotubes.

Background: Social capital has been shown to play an important role in influencing an individual's health, including the incidence of hypertension in adulthood. Adults with hypertension who usually receive services at elderly posyandu with high strata are less likely to develop hypertension than posyandu with low strata. This study aims to determine the relationship between social capital and hypertension in adults in elderly posyandu.Subjects and Method: This study is an observational analytical study with a cross-sectional approach conducted in 25 Posyandu Elderly from May 2024 to July 2024 A total of 200 adult research subjects were selected using stratified random sampling and simple random sampling. The independent variable in this study is social capital and the dependent variable is hypertension. Data collection was carried out using a questionnaire. The analysis test in this study is a multilevel model double logistic regression analysis test conducted using the STATA 13 model.Results: Each increase in one unit of the social capital score will be followed by a decrease in systolic blood pressure of 0.94 mmHg (b= -0.94; 95% CI = -1.48 to -0.40; p= 0.001) and a decrease in systolic blood pressure of 0.32 mmHg (b= -0.32; 95% CI = -0.56 to -0.08; p= 0.008). Each one-year increase in age will be followed by an increase in systolic blood pressure of 0.43 mmHg (b = 0.43; 95% CI = 0.16 to 0.70; p = 0.002) and an increase in diastolic blood pressure of 0.14 mmHg (b = 0.02; 95% CI = 0.26 to 0.70; p = 0.018). There was no difference in systolic blood pressure between men and women (b= -2.84; 95% CI = -8.04 to 2.36; p= 0.284).Conclusion: Individuals who have good social capital lower the risk of hypertension. Increasing age and gender of women increases the risk of hypertension.
