An Exploratory Look at Parents’ Role as Information Provider in Child Autism Diagnoses: Advancing the Theory of Motivated Information Management
Authors: Hays Alexie H. ,   Pennsylvania Communication Association
Published: September 2024

Statistics on autism are rising, and with the diagnosis age as early as two years old, parents have the difficult task of disclosing diagnosis details to their child with autism. Based on the somewhat new Theory of Motivated Information Management (TMIM; Afifi & Weiner, 2004), the current investigation is interested in the criteria parent’s consider(ed) predisclosure of the diagnosis to the child with autism, and how in turn disclosure impacts parental well-being. Through a survey taken by 66 parents of chil-dren on the autism spectrum, results revealed that parent’s dis-closed/plan to disclose accurate diagnosis details because they felt/feel that their child, with whom they feel relationally secure with, would benefit from knowing. This, in turn, helps the parents communally cope with their child and feel positive affect and perceived adaptation towards their child’s diagnosis of autism. Findings from this study have implications for the role of parents as information providers.
“It’s Just Practical”: The Benefits and Barriers of Talking to a Partner about Sexting
Authors: Jenkins Elizabeth M. ,   Pennsylvania Communication Association
Published: September 2024

The current study sought to extend the Theory of Planned Behav-ior perspective to young adult sexting communication in order to help young adults engage in safer sexting. Specifically, this re-search sought to demonstrate how attitudes, subjective norms, and perceived behavioral control impact intentions to talk about sexting with their intimate partner as a form of safer sexting. The quantitative results in the current study were non-significant. However, descriptive statistics pertaining to the benefits and bar-riers of talking to a partner about sexting desires, needs, and limits are discussed as a potential future direction for this re-search. Importantly, the author argues that non-statistically sig-nificant results for health campaign research must be reported within academic journals because of the dire outcomes of creat-ing and perpetuating misinformation to the public through ill-advised health campaigns.

Authors: Chawla Sonia , Goyal Gitanjali , Bhatti Seema , Sarita Ms
Published: September 2024

The word ovarian cancer encompasses a set of tumors with different histology, clinical as well as pathological features, Precursor lesions, and underlying mutations, course of development, prognosis and response to chemotherapy. Though it does not contribute much to overall cancer burden but it is one of the deadliest cancer because of its initial silent and symptomless nature of development. There is no single mechanism elucidating its etiology being a heterogeneous group of disease. Time to time, various researches came into existence explaining mechanism of its development but a clear mechanism did not come into light. Now with increase in studies on high risk women undergoing BRCA related prophylactic Salpingo-oophorectomy, the precursor lesions and mechanism of its development is getting clearer. Here, we will explain pathogenesis, characteristics, site of origin, underlying molecular drivers of alterations of various types of ovarian neoplasms and diagnostic approaches. This knowledge will be helpful in designing effective targeted treatment and early diagnosis for ovarian cancer.

Authors: Rao A Dr. Babitha
Published: September 2024

Food is one of the 3 pillars of Ayurveda as being the base of health; it's always suggested to eat well unctuous freshly cooked easily digestible food. Considering all this home food is always superior and best, though how much ever loyally followed sometimes outside food is unavoidable. So here the motto is to incorporate healthy food as much as possible. So outside food when and how?! The rationale is better than being hungry. Must to consider one's agni (metabolic capacity). prakruthi (Self constitution), desha(place) etc. Minimum criteria to follow are fresh, hygienic, warm, unctuous, healthy, likeable, must eat with whole mind on food neither too slow or fast.If aided with mantra(empowering), daana (feeding the animals, dependents etc) etc more beneficial. Never to be prescribed by peer, marketing etc. Water being vital part of food, locally available clean and warm water preferable. Food is part of daily routine, which adds on to long term health. Even WHO golden rules for safe food as almost included the above criteria. Let's start living and being healthy for achievement of dharma, artha, kaama, moksha as health is base for all this.

Authors: Kozich Zh. M. , Martinkov V. N. , Kovzik N. I. , Blizin D. A.
Published: September 2024

Plasma cell neoplasms are characterized by tumor proliferation of a clone of plasma cells secreting pathological immunoglobulin. The most common types of plasma cell tumor include multiple myeloma, its predecessor smoldering myeloma, monoclonal gammopathy of undetermined significance, as well as rare forms – solitary plasmacytoma and extramedullary lesions with minimal or no bone marrow involvement. Among extramedullary lesions, several forms are distinguished, some of which are associated with bone tissue, and others are extraosseous, located in soft tissues or affecting various organs.

The article presents a rare clinical case of extramedullary lesions with minimal bone marrow changes in a 49-year-old female patient with monoclonal gammopathy of undetermined significance and rheumatoid arthritis. Literature data, clinical manifestations, features of diagnosis and therapy are presented.
Comparative analysis of methodological approaches to assessing accumulated external exposure doses of persons permanently residing in a contaminated area with radionuclides as a result of the Chernobyl accident for the period 1986-1989
Authors: Kulikovich D. B.
Published: September 2024

A comparative analysis of the methods used for assessing and forecasting individual accumulated external exposure doses since the Chernobyl accident showed that conservative approaches to assessing doses and underestimation of indirect dose-forming factors have a negative influence on dose forecasting in general. The proposed new methodological approach of assessing of individualized external exposure doses is consistent with its analogues (Kendall’s concordance factor W=0,96; p<0,03), but at the same time allows taking into account not only the direct dose-forming factor (contaminated density) but also indirect factors in the aggregate (occupational employment, gender and age), which, in turn, makes it possible to reconstruct individualized external exposure doses for each year under study with minimal error. Regression analysis showed that there is a high correlation between new method’s estimates and individual dosimetric control data (R=0,875; p<0,05), the estimation error of the proposed method is ~4 times lower than previous methods.

Published: September 2024

In the article the dynamics of the population (in total, children and people of working and retirement age), mortality and incidence rates were analyzed in 21 districts of the Republic of Belarus contaminated due to the Chernobyl disaster. A decrease in the population in the affected areas was shown. The decline in the urban population is less pronounced, the maximum rate of decline was observed among the rural population of the areas most remote from large cities with developed infrastructure. At the same time, there was no increase in mortality rates in the affected areas and its decrease in the Republic of Belarus by 1,4% per year. Mortality from malignant neoplasms and cardiovascular diseases was 1,5 times higher in the affected areas than in the Republic of Belarus. The incidence rates of all diseases was 1,5 times higher (p<0,05) in the Republic of Belarus. However, the incidence of thyroid and circulatory diseases was significantly higher in the affected areas. The incidence of thyroid cancer was higher in the affected areas, but statistically insignificant, which indicates an equalization of indicators in all areas of the republic.

Published: September 2024

The analysis of the structure of X-ray diagnostic examinations and the levels of effective exposure doses to the population of the Gomel region for the period of 2014-2021 has been conducted based on data of the State Dosimetry Registry.

The dynamics of indicators from 2014 to 2021 are shown.

During the studied period there was a dominance of radiographic (51-54)% and fluorographic (40-35)% methods for examinations in the structure of X-ray diagnostic studies carried out in medical institutions of the Gomel region.

There is a trend towards an increase in the collective effective dose of medical exposure to the population of the Gomel region by 38%. The significant changes in the structure of the collective dose were observed: in 2014 radiographic examinations accounted for 50%, and by 2021 their contribution decreased up to 25%, while the contribution of computed tomography over the corresponding period increased from 15% up to 53%.

The number of X-ray procedures in medical institutions of the Gomel region in average 1,8 per capita annually during the entire observation period. The average effective dose from medical exposure per capita of the Gomel region increased by 44%.
Algorithm for topical diagnosis of parathyroid gland pathology using confocal laser microscopy
Authors: Velichko A. V. , Yarets Y. I. , Rozhko A. V. , Dundarov Z. A.
Published: September 2024

The information content of the confocal laser microscopy (CLM) method for diagnosing of parathyroid gland pathology (adenoma/hyperplasia) in 30 patients who had the clinical and laboratory signs of hyperparathyroidism was analyzed. The pathology of the parathyroid gland was finally verified by histological method, based on the presence of follicle-like structures in the biopsy samples, the absence of stromal fat cells, and the absence of pronounced connective tissue septa. The sensitivity of CLM was assessed in comparison with the methods of ultrasound, CT scan, MRI, and scintigraphy with 99mTc-sestamibi. CLM showed the highest diagnostic accuracy for identifying parathyroid gland pathology with the establishment of a full set of pathognomonic criteria in 76,7% of cases (χ2=74,051, p<0,001). The advantage of CLM was proven by the absence of false negative results, while with ultrasound, scintigraphy, CT and MRI their frequency was 6,7%, 3,4%, 25,0% and 15,8%, respectively. An integrated approach to the instrumental diagnosis of parathyroid gland pathology for the purpose of subsequent surgical treatment is reflected in the developed algorithm. To ensure accurate topical diagnosis with determination of the morphological structure of pathological formations of the parathyroid gland using the CLM method during surgical intervention, a computer program «Hyperparathyroidism» has been developed (registration certificate № 1377, 31.12.2020).

Authors: Traub Andrea , Myszczuk Ana Paula
Published: September 2024

O desenvolvimento é um processo que compreende a ideia de crescimento econômico indo além da capacidade produtiva medida quantitativamente, pois envolve mudanças qualitativas no modo de vida das pessoas e das instituições, sendo medido qualitativamente por meio de indicadores sociais e promovendo mudanças na estrutura socioeconômica de um país. Para impulsionar o desenvolvimento do Brasil foram criadas as regiões metropolitanas que se configuram por áreas urbanas compostas por cidades interligadas entre si que exercem mútua relação de dependência estrutural, social e econômica. A região metropolitana de Curitiba é marcada por desigualdades e contradições entre os seus municípios que evidenciam pobreza, exclusão e segregação socioeconômica. Tem na capital paranaense a sua metrópole, lugar em que acontece a dinâmica econômica e a concentração de riqueza. O presente artigo visa analisar o desenvolvimento da região metropolitana de Curitiba a partir de indicadores socioeconômicos dos municípios que a compõem e os resultados apresentados reforçam um desenvolvimento intrametropolitano desigual com iniquidades econômicas, sociais e de vulnerabilidade social.

Evaluating effect of Inventory controls on financial performance of Small and Medium Enterprises in Eldoret Town, Kenya
Authors: Nyongesa Nanjala Lydia , Munir Muganda Manini , Kamau Charles Guandaru
Published: September 2024

Inventory management is essential for maintaining optimal stock levels and minimizing costs, which ultimately affects a firm's overall financial performance. This study focuses on the impact of inventory controls on the financial performance of small and medium enterprises (SMEs) in Eldoret town. Inventory controls are measured through various dimensions, such as inventory levels, inspection, auditing, and management systems. Previous research has shown that effective inventory management can increase a firm's profitability by reducing unnecessary stock holding costs and avoiding stockouts. To investigate this further, a descriptive research design was employed, and data was collected from 171 SME owners/managers through self-administered questionnaires. Descriptive statistics and regression analysis were used to analyze the data. The results revealed a significant positive relationship between inventory controls and the financial performance of SMEs. Specifically, the inventory controls explained 11.5% of the variance in financial performance. These findings suggest that SMEs that implement efficient inventory management practices tend to experience better financial outcomes. Therefore, it can be concluded that effective inventory control mechanisms are crucial for enhancing the competitiveness and growth of SMEs. Consequently, this study recommends that SME owners implement robust inventory control systems to maximize their financial performance.
Comparing the Performance of Using a Smart Damper in a Semi-Active ‎‎Suspension Instead of a Traditional Damper Using MATLAB/Simulink
Authors: Ali Lamyaa Mahdi , Al Zughaibi Ali  ‎ I.
Published: September 2024

‎ Given the importance of comfort and safety in various driving circumstances, the suspension system emerges as the most ‎crucial component. Two different suspension systems, passive (PSS) and semi-active (SASS), are compared for effectiveness in ‎this research. MATLAB/Simulink is used for simulation, employing a representative two-degree-of-freedom car model to ‎evaluate and compare the performance results of these systems. The differential equations of motion for the two systems are ‎modeled and simulated using software, which illuminates how they would behave under the same parameters and ‎circumstances. Additionally, a Magnetorheological damper (MR) model with a ¼ vehicle system is used to evaluate its behavior ‎on various types of roads, including those with steps, bumps, and random inputs. This study utilizes the Bingham plastic model ‎to compare the simulation results of SASS and PSS systems. After comparing the numerical and graphical results from the two ‎systems, it is observed that SASSs with controllers perform better than PSSs in terms of suspension adjustment and response ‎time. The SASS is superior to the PSS in suppressing oscillations by 55.12%, 77.47%, and 86.78% for step input, bump, and ‎random inputs, respectively. Additionally, the SASS is faster in eliminating oscillations compared to the PSS by 54% and 51.7% ‎for step input and bump inputs, respectively. ‎ ‎

Agriculture is the only provider of human food. However, currently demand seems to exceed the limitations of conventional farming practices, as the latter often rely on scarce resources. The focus of agricultural research appears to be shifting towards another approach, namely sustainable farming, which is hoped to pose a solution for the aforementioned issue. Considerable yield and farm resilience are expected from such a practice to withstand and mitigate negative effects of climate change and provide for human well-being. This paper aims to investigate such possibilities focusing on the Carpathian basin’s climate. First, current trends are analyzed, then ecological farming and its challenges are explained in further detail. Finally, agroforestry is introduced as an approach and framework to react to these challenges. As a result, connection points are highlighted which indicate that combining ecological farming with agroforestry could indeed be the basis of a safe and sustainable agriculture.

Regarding the realization of the right to proper administration established by the RA Constitution, the establishment of such principles and ensuring their practical applicability have become problematic today, which would really guarantee the right of the non-governmental party to proper administration in the administrative process carried out by the administrative body endowed with public authority.

The article presents the factors that have an impact in administrative and legal activities to ensure the functioning of this principle.
