Authors:   , Currier Michael P.
Published: December 2024

The objective of this thesis is to clarify the taxonomy of Lupinus leucophyllus Dougl. The morphological variability observed, has historically rendered the group as difficult, although the species has clear diagnostic characters and is easily recognizable today. Morphological analysis is combined with thin-layer chromatography of alkaloids and geographic information to arrive at a feasable taxonomic treatment at the subspecific level. Principal Components Analysis of 34 morphological attributes resulted in clusters of similiar morphological affinity. Three subspecies are named based on the evidence: ssp. leucophyllus, ssp. retrorsus, and ssp. erectus. They are characterized by distinct morphological attributes, ecological adaptation, and geographic distribution. The subspecies leucophyllus contains three varieties. Varietal designations acknowledge morphologically distinct variants with broad distribution.
Computer aided process-selection
Authors:   , Dhanju Yadvinder S.
Published: December 2024

This paper describes an expert system for manufacturing process selection in the early part of the design phase. Often the designer commits to a particular manufacturing process and goes on to design the part keeping that process in mind. Each process is limited in its ability to produce functions like surface finish, tolerance, batch size and shape. Demand for better surface finish or closer tolerances than what the process is capable of providing, results in extra cost. The expert system eliminates this extra cost by providing all the possible optimum processes that are consistent with the requirement, in very early stages of the design. The program uses object-oriented programming for pruning the processes. It was developed on the Xerox 1186 and will be a precursor to a much larger and more comprehensive system.
Vision sensing object and number recognition for robotic applications
Authors:   , Eskandari G. Reza
Published: December 2024

Social and economical advantages of automation has made robotic systems a vital part of manufacturing. The key to a successful automation is a robotic system which has the ability to sense its work frame in addition to doing the physical labor involved. Machine vision is one of the most powerful of all sensors. Of course it is not restricted to robotic applications, but it started as an added sense for robots and that will probably be its main use for some time to come. The purpose of this study is to develop a computer integrated system for object recognition by two dimensional geometrical shape and part number recognition. The recognized objects are then transferred to their prescribed locations. The classical moment methods utilized for image analysis are presented.
The Missouri livestock auction in 1977
Authors:   , Hensley Jay C.
Published: December 2024

"Since colonial America, as early as 1676, livestock auctions have played a role in U.S. agricultural marketing. They we re developed initially as a market day or fair in the Boston area but quickly developed into meat auctions, the slaughtering being done in the outlying districts. Unfortunately, there has been little written about early developments in livestock auction selling; however, historians generally agree that the first auction for which records are available was conducted by the Ohio Company for Importing English Cattle. The company was begun in 1836 by a group of Ohio stockmen who arranged for the importation of purebred breeding stock. During the next twenty-five years or so, a number of such companies developed in Ohio and Kentucky, all dealing in imported breeding cattle. One such company, the Madison County Importing Company, was established at London, Ohio, in 1853. Records show that by 1859 this company was marketing one thousand head of livestock per sale day."--Introductions.
An economic analysis of Mexico's dairy, livestock, and poultry sector : implications for feed demand
Authors:   , Burst Andrew C.
Published: December 2024

Over the last several decades, Mexico has experienced annual rates of growth in both population and per capita real incomes in excess of three percent. These increases in population and incomes, changing dietary habits, and government policymakers attempts to increase the nutritional levels of the Mexican populace have all been translated into increases in the demand for higher protein food commodities. The principal source of this higher protein food is the Mexican dairy, livestock, and poultry sector. The principal objectives of this study were: 1) to identify and analyze the sources of growth of the Mexican livestock and poultry subsectors and major structural and technical constraints to its further development, and 2) to determine both the implications that these factors have had on aggregate feed demand, as well as Mexico's ability to satisfy domestic feed demand requirements. The study utilized data from a variety of secondary data sources. Factors impacting demand, such as demographic and income dynamics were discussed and analyzed. Within the dairy, livestock, and poultry sector, major changes and patterns in production, trade, supply, and prices were identified. To determine the ability of Mexico to supply major feed ingredients--feed grains and oilseeds--trends and patterns in grain and oilseed consumption, production, trade, and prices were also overviewed. The influence of government policies and programs and major marketing institutions on the supply of, and the demand for, dairy, livestock, poultry, and crop sector output was also analyzed. Supplying the domestic market with animal proteins has resulted in substantial increases in livestock and poultry populations and industry productivity. A major factor in these increases has been the movement of various subsectors--notably poultry, swine, and dairy--towards more intensive, confined animal feeding systems. Government intervention was also shown to have had a major impact on the growth and development of the sector in general and the egg and dairy industries in particular. Mexico's crop sector also reflects the growing importance of major livestock and poultry industries. Substantial growth has occured in domestic output of major animal feed ingredients--grain sorghum, soybeans, and safflower. However, although impressive, these gains have been insufficient to supply domestic demand. As a result, Mexico has turned increasingly toward international markets to satisfy domestic feed input requirements. These developments have major implications for United States' agricultural exports. In 1981, Mexico was the third largest foreign market for U.S. agricultural products. Mexico's 1981 imports of U.S. grain sorghum and soybean and soybean meal, for example, totaled U.S. $330 million and U.S. $230 million, respectively.
Some socio-economic considerations in the Bedouins' agricultural settlement (an example from Libya)
Authors:   , El-Wifati Bashir M.
Published: December 2024

Agricultural settlement is one important policy goal adopted in Libya, and many other developing countries in Africa and the Middle East, to improve the level of living in rural areas. These countries share several general characteristics. Their agricultural production is low. They have a high percentage of nomadic and seminomadic people in their rural populations. They face a high rate of migration from rural to urban areas. Development under such conditions not only requires providing the right quantities and qualities of physical inputs, but also the selection of the most promising settlers as well. Therefore, this study of the "Gebel Al Akh dar" settlement scheme was designed to indicate the major sources of income of farmers on the project as well as to identify the major influences on their farm output. Hence, an attempt was made to identify factors which are essential for farm success in an unfavorable agro-climate environment. Specifically, the objectives of the study were: (1) to explain the variation in net farm income on the project, (2) to investigate the social and the economic conditions of the settlement scheme, and (3) to study the economic conditions of the settlers by investigating their levels and sources of farm income. Data for the study were collected by personal interview from a random sample of 120 farms. The framework of analysis used in testing the hypothesized relations were multiple regression, "t" tests on differences between mean incomes, and simple analysis of variance. Factor analysis was used in constructing two indices of modernization which, in turn, were regressed on selected socio economic variables. Sources of differences in incomes for settlers by project areas were examined using "t" tests on mean differences and analysis of variance tests. A stepwise multiple regression format with the "mean residual sum of squares" criterion (MSE) was used to identify the significant and relevant variables included in the production function analysis. The analysis suggested some alterations are needed in policy decisions with respect to farm inputs, selection and training of settlers, and research programs. For example, hired labor was found to be more rewarding than the use of tractors and other inputs on the scheme. This suggests that the machinery-labor mix of the project needs to be reconsidered. Also, the traditional attitudes of settlers, found to be elements of success in farming, direct the attention to new criteria for settler selection. Finally, since management ability was the most important variable on both dry and irrigated farms, training programs are needed that focus on local agricultural problems while considering abilities of settlers and the region's social and economic conditions.
The economics of land disposal of municipal effluent
Authors:   , Milde Louis Mark
Published: December 2024

"INTRODUCTION: The State of Missouri presently is faced with a problem of ever-increasing dimension. Most municipalities presently discharge waste waters into streams. This practice often results in degradation of overall water quality. Increasing concern in this area has brought about the development of new, highly-sophisticated, advanced treatment facilities. However, a high degree of treatment by these conventional methods of treatment has been accompanied by a corresponding high cost. The high cost of advanced treatment has kept municipalities from installing facilities of this nature. Consequently, more economical methods of advanced treatment are sought by municipalities. One such method lies in the form of advanced treatment of municipal sewage effluent by means of irrigating agricultural land. This approach offers considerable merit because: irrigation systems presently available are capable of handling large volumes of water; the soil-plant complex is a very effective rennovation media, capable of utilizing both nutrients and the excess water; and finally, reuse of the potential pollutants and water effluent provides the municipality with additional economic return through crop production."--Page 1.

Interactions of formamidines with the platelet serotonin uptake system
Authors:   , Johnson Terry L.
Published: December 2024

An important aspect of toxicology is the determination of the actions of pesticidal compounds. In addition to providing information on the mechanisms of toxicity such studies also provide knowledge of the physiology and biochemistry of affected target and non-target species, and can lead to the future development of effective and selective pesticides. Some types of pesticides, such as organophosphate insecticides, have a well-defined mode of action. However, information about the actions of members of other classes of compounds remains obscure. The formamidines are one such group. The forerunner of the formamidines is chlordimeform or N'-(4-chloro-o-tolyl)-N, N-dimethylformamidine. Chlordimeform, which is sold under the brands Galecron [registered trademark] and Fundal [registered trademark], is active against insects and acarines and is especially toxic to those that are resistant to organophosphates. Chlordimeform and other formamidines are known to interact with physiologic processes involving biogenic amines in both arthropods and mammals. Since biogenic amines include important neurotransmitters and neurohormones, interference with their formation, degradation, or function could have serious physiological consequences. For example, an essential regulatory function at aminergic synapses and receptor sites is the uptake of neuroactive biogenic amines. Interference with amine uptake at these sites could result in abnormal physiological and behavioral actions. Rat blood platelets provide an easily accessible model for the study of amine uptake mechanisms. Thus, it was used to investigate the influence of chlordimeform and other formamidines on the uptake of serotonin or 5-hydroxytryptamine (5-HT). The specific objectives of this investigation were: 1. To determine whether chlordimeform inhibited the uptake of 5-HT by rat blood platelets, 2. To determine the relationship between formamidine structure and 5-HT uptake inhibitory potency, 3. To study the mechanism by which formamidines inhibit 5-HT uptake using chlordimeform as a model compound, and 4. To determine the effect of formamidines on the release of 5-HT from platelets.

...This sixteenth study, a continuation of the project, covers one of the most interesting sections of the state. The district of the Sainte Genevieve was one of the political divisions in what is now Missouri during the French and Spanish occupations and under the American territorial government until 1812. It is difficult to indicate the boundaries; however, this district may be said to have been bounded on the east by the Mississippi, on the north by the Meramec, and on the south by the Apple Creek. At first it extended west indefinitely, but later the Meramec seeems to have been set as the western limit. The five counties treated in this study are included entirely or in part in this division: all of Ste. Genevieve, St. Francois, and Washington, the greater part of Crawford, and a considerable part of Iron. This section of the state is rich in history, and to make a study of its place names is to learn much of the early days of settlement and accomplishment in the state...Pages ii-iii.
Effect of sulfur dioxide treatment on wheat straw digestibility
Authors:   , Thomson John Ralph
Published: December 2024

"Need for Protein : The present world population was estimated to have recently passed the four billion mark. The annual growth rate is approximately 2.1 percent which gives a doubling time of 33 years. Thus by the year 2010 it is estimated there will be a world population of eight billion people.(1) The world's population is presently fed primarily by conventional agriculture based on primary inputs of sun, water, and arable land. It is estimated that there are 7.86 million acres of potentially arable land.(2) About half of the best, most accessible land is presently being cultivated. If all of the available land were to be brought into agricultural use at the present levels of production this would not be enough to maintain the current level of nutrition past the year 2000. In addition it is highly unlikely that all of the remaining land will be brought into agricultural use due to the high capital cost associated with developing it and other limitations such as water, fertilizer, and energy. The world population is therefore rapidly outgrowing its food supply. A new source of food, and more specifically, new sources of protein must be developed that do not require land as a major input."--Introduction.
A holographic interferometry study of an axisymmetric shock-wave/boundary-layer strong interaction flow
Authors:   , Dunagan Stephen E.
Published: December 2024

An experimental study of the axisymmetric shock-wave/ turbulent boundary-layer strong-interaction flow generated in the vicinity of a cylinder-cone intersection has been conducted. The present data are useful in the documentation and understanding of compressible turbulent strong-interaction flows, and are part of a more general effort to improve turbulence modeling for compressible two- and three- dimensional strong viscous/inviscid interactions. The nominal free-stream Mach number was 2.85. Tunnel total pressures of 1.7 and 3.4 atm provided Reynolds number values of 18 x 106 and 36 x 106 based on model length. Three cone angles (12.5 [degrees], 20 [degrees], and 30 [degrees]) were studied giving negligible, incipient, and large scale flow separation respectively. The initial cylinder boundary layer upstream of the interaction had a boundary-layer thickness of 1.0 cm. The subsonic layer of the cylinder boundary layer was quite thin, and in all cases, the shock wave penetrated a significant portion of the boundary layer. Owing to the thickness of the cylinder boundary layer, considerable structural detail was resolved for the three shock-wave/boundary-layer interaction cases considered. The primary emphasis in this study was on the application of the holographic interferometry technique to these flow cases. The density field was deduced from an interferometric analysis based on the Abel transform. Supporting data were obtained using a 2-D laser velocimeter, as well as mean wall pressure and oil flow measurements. The attached flow case was observed.to be steady, while the separated cases exhibited shock unsteadiness. Comparisons with Navier-Stokes computations using a two-equation turbulence model are presented. The study illustrates the utility of holographic interferometry for detailed instantaneous flow-field characterization and provides documented data useful in the evaluation of computational schemes.
Yeast mutants containing elevated methionine
Authors:   , Tarka Eugene F.
Published: December 2024

Yeasts are deficient in methionine which restricts the nutritive value of the protein. The objective of this research was to produce a methionine-rich mutant. Mutants of Candida tropicalis is ATCC 1369, Candida tropicalis ATCC 9968, Candida utilis ATCC 9950, and Saccharomyces cerevisiae ATCC 862 with increased methionine, the limiting amino acid in yeast protein, content were isolated. None differed from the parent strain as to carbon assimilation or vitamin requirements. The mutants were obtained by treatment with ultraviolet (UV) irradiation, or nitrous acid (NA) or selection for ethionine resistance. The UV-and NA-derived mutants grew on a methionine-free medium and exhibited an increased growth response to sulfate added to a sulfate-free medium. The mutant exhibiting the largest increase in methionine content was 1369/0, an NA mutant, in which methionine was increased 54.6 percent as a percentage of the protein above that of the parent strain. Of the 17 amino acids recovered, the increase was 9.4 percent. The increase in the recoverable amino acids was 2 percent, of which methionine constituted 15 percent. The increase of the mutant 1369/0 over the parent in relative nutritional value (RNV) was 4.35 percent, which is of marginal significance. Sonication of the yeast cells increased the RNV an average of 8 percent above that of the intact cell RNV.
Potential of business uncertainty indicators in forecasting economic activity: The case of Russia
Authors: Lola Inna S. , Asoskov Dmitry G.
Published: December 2024

This study investigates the utility of business uncertainty indicators as predictive tools for forecasting economic activity in the context of Russia. In an era characterized by global economic volatility and geopolitical shifts, understanding the dynamics of economic uncertainty and its impact on overall economic performance is of paramount importance. The study utilizes a comprehensive dataset based on the results of business tendency surveys in Russia, spanning the period from 2009 to the first half of 2024. Given the importance of uncertainty in shaping economic outcomes, the central research question of this study is: can uncertainty indicators predict business activity in Russia or not? To address this question, we compared two alternative approaches to calculating business uncertainty: the ex‑ante approach, which uses the business community’s assessments of future business trends to measure uncertainty as the dispersion of opinions expressed, and the ex‑post approach, which applies entrepreneurial assessments of both future and current trends to determine business uncertainty as the degree of deviation of entrepreneurial expectations from the real picture. National indicators and sectoral indicators were calculated for the mining and quarrying industry, manufacturing industry, construction, retail trade, wholesale trade and services. For most of the industries under consideration (except for the construction and service sector) and at the national level, the specifications of vector autoregression models that were effective for forecasting real indicators of economic activity, ­characterized by lower forecast ­errors compared to standard autoregressive models, were built. According to the results obtained, at the national level, when forecasting GDP, clear preference should be given to the ex‑post indicator.
The diversity of income effects on mortality across regions in People’s Republic of China: Instrumental variable approach
Authors: Nagapetyan Artur R. , Pavlova Tatiana I. , Li Jun
Published: December 2024

The issue of equality of opportunity is crucial in contemporary society, often examined in relation to income. Previous research has demonstrated the uncertain effect of income on mortality due to the presence of other factors. To empirically assess the difference in the effect of income on mortality rates between more developed and less developed provinces in China, we modeled mortality rates based on the instrumental variables method and the generalized method of moments. The study results indicate that a 1% increase in income reduces mortality by over 2%. The results confirm the hypothesis that income has a stronger negative impact on mortality in more socially developed provin­ces of the People’s Republic of China compared to less socially developed areas. This difference is statistically significant at the 1% level and is at least 10%. The obtained results and their development can significantly impact the implementation of effective political governance measures aimed at reducing mortality in certain territories and mortality in general.
Machine learning algorithms for predicting unemployment duration in Russia
Authors: Maigur Anna A.
Published: December 2024

Predictions of the individual unemployment duration will allow to distribute target support while searching for a job more effectively. The paper uses survival models to predict the unemployment duration based on data from Russian employment centers in 2017–2021. The dataset includes socio-demographic characteristics, such as age, gender, education level, etc., as well as the job search duration. Two models’ forecasts are investigated: the proportional and the non-proportional hazards models. Both models take into account censored data, but only the second one captures nonlinear dependencies­ and the disproportionate influence of independent variables over time. The forecast quality is estimated with the C-index, equality of which to 1 indicates the most accurate forecast. The highest index value is demonstrated by the non-­proportional hazards model (0.64). Moreover, it was found that variable that contributes the most to the prediction quality is region of a job search so that job-search time is heterogeneous among different regional labour markets. To sum up, forecast quality is quite high and stable over time and the implementation of model forecasts by employment centers will increase their efficiency.
Russian economic development under forceful defense spending growth
Authors: Buklemishev Oleg V.
Published: December 2024

The article examines historical aspects, general economic logic, and theoretical discussions on the policy of stimulating the economy through increased government appropriations for defense items. It provides a brief overview of empirical studies on economic effects of defense spending in Russia and other countries. The secondary nature and low manageability of economic effects of defense policy are emphasized. The size of the fiscal impulse due to defense items of government expenditure, its positive and negative effects are analyzed in the Russian economy for the period 2022–2024. In addition to the unlikely gains through security and supply channels, the limited availability of free production capacity and labor force are stressed among the factors hindering the positive demand effects of increased defense spending. This gives rise to inflationary consequences, as well as the contradiction between tightening monetary conditions and continuing fiscal stimulation. A conclusion is made about the prevalence and possible aggravation of negative outcomes of sustaining and expanding military outlays.

Cyber Security in Smart Cities: Role of 5G Technologies the Indian Perspective
Authors: Putarjunam R  , Kala N
Published: December 2024

The UN-Habitat World Cities Report 2022 published in June 2022 states that, population in urban areas of India is estimated to reach at 675 million and will be 43.2 percent of its total population by 2035. It will be the second highest figure, behind China’s one billion. In last two decades, India and China experienced rapid urbanization and economic growth. As a result, number of people living in poverty reduced [1]. The Government of India launched “The Smart Cities Mission (SCM)” on 25 June 2015[2]. The aim is to spearhead development and quality of life in urban areas with the help of IT and IT enabled services. The smart cities in India though growing in numbers are more of an up-gradation of the old legacy township where the basic amenities and infrastructure are being given a fresh look with implementation of the modern tools and development techniques. Presently many legacy manual systems for essential services like power, water, communication, transport and many public distribution systems lack the resources and capacity to meet the growing demand and aspirations of people. Most smart cities are seeing uncontrolled and uncoordinated developments with various agencies working in their comfort zones and SILOS have failed to adequately address the role of cyber security that comes as potential risk with such modern IT enabled services. Adherence to standards and protocols for cyber security in the smart city sector are mostly missing or being adopted in an adhocmanner.Since the concept of changing urban life style in the Smart Cities is in a very nascent stage, it throws lot of challenges for the administration to deal with issues of cyber attacks. This research is aimed at identification and analysisof potential cyber security risks and challenges of smart cities. The focus will be to understand the entire ecosystem of smart city challenges and desired security standards, various security regulatory frameworks in world &India and how they can be adopted to the Indian scenario. Further the latent capabilities and advantages of using 5G technology has been touched upon in conjunction with how its adoption id developing the Smart Cities can help. This research finally proposes a way ahead to an integrated approach to smart city development, exploiting the available technologies.

Pyloric web : Management of a neglected case of Gastric Outlet Obstruction
Authors: Agarwal Nishant , Kumar Tarun , Kanneganti Pujana , Verma Anju , Kumar Basant
Published: December 2024

Pyloric atresia is an extremely rare cause of gastric outlet obstruction, constituting approximately 1% of all gastrointestinal atresias and occurring in about 1 in 100,000 live births. It is equally prevalent in males and females and may exhibit autosomal recessive inheritance. Clinically, it presents during infancy with non-bilious vomiting, abdominal distension, and failure to thrive. Type 1 pyloric atresia, characterized by a pyloric membrane with an opening, is exceptionally rare and may present later in childhood. We reported the case of a 5-year-old male with the history of recurrent non-bilious vomiting since the age of one year, which worsened over the preceding four months. Examination revealed visible peristalsis and upper abdominal fullness. Radiological findings suggested gastric outlet obstruction, and exploratory laparotomy confirmed Type 1 pyloric atresia. Surgical management involved excision of the pyloric web and Heineke-Mikulicz pyloroplasty. The child had an uneventful recovery and demonstrated significant improvement in weight and nutritional status at a 6-month follow-up. The diagnosis of pyloric atresia is challenging due to its rarity and similarity to other conditions like duodenal atresia or hypertrophic pyloric stenosis. Early diagnosis through clinical suspicion, radiological evaluation, and definitive surgical intervention is crucial to prevent complications such as aspiration pneumonia and metabolic imbalances. This case highlights the importance of considering pyloric atresia in children with recurrent vomiting and failure to thrive, even beyond infancy, and emphasizes the significance of prompt surgical management for favorable outcomes.
A Cross-Sectional Study of the Prevalence of Short Stature Among Children Visiting the Outpatient Department of a Tertiary Care Center
Authors: Shrivastava Dr. Mohit , Anand Dr. Shweta
Published: December 2024

Background: Short stature in children is a significant global health concern, often indicating underlying nutritional, endocrine, or genetic disorders. Identifying the prevalence and associated risk factors in specific populations in regions with limited access to healthcare, poor nutrition, or inadequate prenatal care eg in rural or low-income communities, is essential for early diagnosis and timely intervention. Objective: This study aimed to assess the prevalence of short stature among children visiting the outpatient department of a tertiary care center and to explore the sociodemographic (lower SES, nuclear families) and clinical factors {chronic illness like hypothyroidism, diabetes, and bone age} associated with short stature. Methods: A cross-sectional observational study was conducted at the Department of Pediatrics, LN Medical College, and JK Hospital, Bhopal. A total of 210 children aged 2-12 years attending the outpatient department were systematically selected (systematic sampling) and approved by the IEC. Inclusion criteria involved children whose parents or guardians provided informed consent, while exclusion criteria included children with hypotension or those whose guardians did not consent. Anthropometric measurements, clinical assessments, and family histories were recorded. Short stature was defined as height-for-age below -2 standard deviations from the WHO growth standards. Results: The prevalence of short stature was 4.29%. It was more common among children from lower socioeconomic backgrounds (55.6%) and nuclear families (66.7%). The highest prevalence was observed in children aged 5-8 years (77.8%), with no significant gender difference. Additionally, 77.8% of children with short stature had a chronic illness, such as hypothyroidism or diabetes. And 88.9% showed delayed bone age. The influence of maternal education was also significant, with 55.6% of affected children having illiterate mothers. Conclusion: The study found a relatively lower prevalence of short stature compared to other studies, but it was significantly associated with lower socioeconomic status, chronic illness, delayed bone age, and maternal education. Early detection, nutritional interventions, and addressing socioeconomic disparities, enhancing maternal education are essential to improve growth outcomes in children. Further research is needed to investigate the long-term outcomes of children with short stature and the effectiveness of targeted interventions.
Impact of Social Media on Self-Esteem Among Nursing Students
Authors: Arora Kritika , Gupta Ravinder Kumar , Gupta Urvi , Babber Sunny , Moza Indra
Published: December 2024

Introduction: The rise of social media has transformed communication dynamics, particularly among nursing students who utilise these platforms for social interaction and academic collaboration. While social media can enhance self-esteem through connection and validation, it also presents risks associated with negative social comparisons, particularly for students under academic stress. Materials and Methods: This cross-sectional study included 185 nursing students from a college, with 160 consenting to participate. Data were collected through an online survey comprising a demographic questionnaire, the Social Networking Use Questionnaire (Gupta & Bashir), and the Rosenberg Self-Esteem Scale. Statistical analyses were conducted using IBM SPSS version 21, employing independent t-tests, ANOVA, and Pearson correlation coefficients. Results: The participants' mean age was 18.76 years, with an average social media usage of 5.24 hours daily. Results indicated a strong correlation between time spent on social media and self-esteem (r = 0.342, p < 0.01), while social interaction showed a weaker correlation (r = 0.233, p < 0.01). Notably, entertainment and informativeness dimensions did not significantly correlate with self-esteem (r = 0.092, p = 0.861; r = 0.061, p = 0.923). Discussion: The findings reveal a complex relationship between social media use and self-esteem. While social media provides valuable opportunities for connection and information, excessive use can lead to negative self-perceptions. The lack of strong correlations between self-esteem and dimensions like informativeness and entertainment suggests that while these elements are enjoyable, they do not significantly enhance self-worth. Conclusions: This study highlights the nuanced impact of social media on nursing students' self-esteem. Future research should investigate conditions that promote positive self-worth versus those that exacerbate negative feelings, informing strategies to foster healthier social media engagement among students.

BuCy-E ve BEAM, lenfoma tedavisinde yaygın olarak kullanılan iki hazırlık rejimidir ve bu çalışmada her iki rejimin kısa dönem sonuçları retrospektif olarak incelenmiştir. On ikisi Hodgkin Lenfoma (HL) ve 18'i Non-Hodgkin Lenfoma (NHL) tanısı alan toplam 30 hasta çalışmaya alınmıştır. Hastaların demografik özellikleri, tedavi yanıtları, yan etkiler ve toksisiteleri kaydedilmiştir. Elde edilen bu veriler her iki rejim için istatistiksel olarak karşılaştırılmıştır. Her iki grup arasında yaş, cinsiyet ve tanı açısından anlamlı bir fark bulunmamıştır. Febril nötropeni BEAM grubunda istatistiksel olarak daha yüksek oranda bulunmasına rağmen fungal enfeksiyonlar arasındaki fark istatistiksel anlamlılığa ulaşamamıştır. BEAM grubunda şiddetli mukozit daha sık görülmüştür. Her iki grupta bulantı, kusma ve diyare benzer seviyelerde görülmüştür. BEAM grubu, median PFS açısından BuCy-E’ye göre anlamlı şekilde daha üstün bulunmuştur (23 ay vs. 12 ay, p = 0.0044). Median OS’de ise BEAM grubu daha avantajlı görünmekle birlikte (23 ay vs. 12 ay), bu fark istatistiksel olarak anlamlı değildir (p = 0.179). BuCy-E ve BEAM rejimleri, kısa dönem toksisite profilleri açısından karşılaştırılabilir olup, BEAM rejimi PFS açısından üstün bir sağkalım sunmaktadır. Ancak, BEAM rejiminde febril nötropeni gibi yan etkilerin daha sık gözlenmesi dikkate alınmalıdır. OS açısından gruplar arasında istatistiksel olarak anlamlı bir fark bulunmamakla birlikte, uzun dönem sonuçlar için daha geniş hasta gruplarında ve uzun süreli takiplerle yapılacak prospektif çalışmalara ihtiyaç vardır. BuCy-E rejimi, daha düşük toksisite profili nedeniyle belirli hasta gruplarında etkin bir alternatif olarak değerlendirilebilir.
Самоменеджмент як вияв нової форми лідерства в умовах воєнного часу

Самоменеджмент як вияв нової форми лідерства в умовах воєнного часу зорієнтовує дослідників у царині менеджменту на особистісні аспекти. Зокрема, характеризування самоменеджменту не як soft skill менеджера, а як однієї з форм виявлення лідерства розкриває дуже сучасний підхід у дихотомії «керівник- лідер», зокрема – здатності до самоуправління як ключової риси, що диференціює управління від лідерства. Підкреслено, що саме необхідність виходити за рамки звиклого розв’язування задач чи то стратегічного, чи тактичного, чи оперативного характеру сприяють розвитку людського капіталу на підприємстві. Таким чином, сформувалися передумови того, що управління, не пов’язане із лідерською компонентою, не в змозі повно зреалізувати власні функції в складних ситуаціях, коли слід формувати перспективи розвитку попри війну, а виявом, що індикує цю компоненту, є самоменеджмент.

Ключові слова: лідер, лідерство, управління, людський капітал, самоменеджмент.

It is stated that modern reform processes in the healthcare sector have a significant impact on the proof of criminal offences. The author analyses scientific approaches to clarifying the circumstances to be established from the perspective of criminal law, criminal procedure and forensic nature. The generally accepted classifications of circumstances to be established in criminal offences include those to be determined on the facts of entering false information into the electronic healthcare system, in particular, the identity of the employee of a medical institution who has the authority to input information into the electronic healthcare system (level of personal access (administrator, user); his/her relationship with the management of the institution and other employees; information about the medical information system used by the healthcare facility. The problems of identifying the person whose information is entered into the electronic healthcare system of Ukraine are emphasized. The author provides the circumstances in the case of qualification under Article 191 of the Criminal Code of Ukraine, in particular, the author emphasizes the need to establish the mechanism of misappropriation of funds received from the NHSU to the accounts of a medical institution, the amount of damage caused to the National Health Service of Ukraine, the amount of funds encroached upon by offenders, the facts of violation of the law, etc. The article provides recommendations on algorithms for conducting certain procedural actions to establish the circumstances of a criminal offence.
