Heavy metal contamination of water is a widespread problem in Peru and represents a potential threat to the ecosystem. Bacteria are an ecological alternative to treating these effluents. This research aims to determine the influence of temperature and pH on the lead (Pb) bioremoval in surface water using Serratia marcescens under laboratory conditions. The sample was collected from a stream located in Santiago de Chuco City (Peru). Treatments (T) were carried out by combining pH (5 and 7) and temperature (25, 30, and 35 °C). The bacterial inoculum (S. marcescens) was 3 × 108 CFU/mL, which was constant in all treatments. The lead bioremoval evaluation was performed in an airlift bioreactor and the incubation time was 24 h. The total lead concentration was determined using atomic absorption spectrophotometry. The results show that treatment 6 (temperature: 35 °C, pH: 5, and inoculum: 3 × 108 UFC/mL) showed a better result than the other treatments, with a removal value of 63.94%. Furthermore, the total lead concentration decreased from an initial concentration of 0.268 mg Pb/L to a final value of 0.0964 mg Pb/L. These results are still above the allowed water value (15 µg/L) according to Peruvian standards. On the other hand, temperature and pH influenced lead removal from surface water when S. marcescens was used after a short incubation period (24 h). Although an attempt was made to improve lead bioremoval by varying two parameters, temperature and pH, future research is still needed to investigate the effect of different inoculum concentrations, the use of microbial consortia, and a broader range of physicochemical parameters.
Tutoring—An Emerging Phenomenon in the Romanian Education System
Authors: Ciuchi Oana Mariana
Published: September 2023

This paper, without intending to be exhaustive, is a presentation of an increasingly prominent social reality: the tutoring of pupils, as a parallel educational activity complementary to the education system, as a form of non-formal education, or as an alternative option for students’ parents to support them in their social success. Our research aimed to identify the perception/opinions of the beneficiaries of these tutoring activities, in relation to the relevant aspects of such activities, such as the way they are organized and carried out, the type and motivational level of students participating in such activities, the real dimensions of the phenomenon as manifested in Romanian society, etc. In order to achieve the purpose of our research, a questionnaire, with open-ended and closed-ended questions, was given to a significant number of people bearing the title of student, who had completed high school studies only 1–4 years ago. Based on the research carried out, it was possible to identify a hierarchy of motivational factors that determine whether students resort to tutoring; the causes of the occurrence and expansion of this phenomenon; and the opinions of the beneficiaries of tutoring services towards the organization and conduct of these activities. At the end of the article, some measures are presented that could optimize the balance between formal and non-formal education in Romanian society.

Authors: Chen Xinglin , Yang Fuqiang , Cheng Shuo , Yuan Shuaiqi
Published: September 2023

The frequent occurrence of various occupational accidents has resulted in significant casualties and occupational disease issues, which hinder economic and social development seriously. The promotion and enhancement of occupational health and safety (OHS) require greater efforts to be made to achieve sustainable economic development, particularly in developing countries. With remarkable progress and achievements that have been made in terms of OHS in China, a systematic and thorough review is needed to gain insight into the development process, current status, and research trends regarding OHS in China. Additionally, pathways for future work need to be discussed to boost the OHS development in China in the new era. Therefore, a systematic literature review is performed in this study to investigate the development of OHS in China with the help of a bibliometric analysis. Firstly, a total of 5675 publications related to OHS in China between 1979 and 2022 were collected from the Web of Science Core Collection (WoSCC) and the Chinese Science Citation Database (CSCD) before being refined manually. Then, the temporal distribution and journal sources of the collected publications were analyzed before the collaboration networks of the “productive institutions” and “productive authors” were discussed. Furthermore, the key research topics (e.g., disease prevention, psychological safety, occupational exposure) and dominant research methods (e.g., epidemiological methods, risk modeling) associated with OHS during different periods were identified and discussed based on the keywords and bibliographic analysis. Finally, the current needs and promising pathways for future work were discussed. It is suggested that the prevention and control of conventional and new occupational diseases, the protection of workers’ occupational health rights and interests, the development and implementation of advanced technologies for OHS, and the development of more sophisticated and efficient health and safety risk assessment models may be focused on to accelerate the development of OHS in China. This study systematically reviews the development processes, current status, and future prospects regarding OHS in China. The results of this study provide valuable insights for researchers and practitioners who are involved in the Chinese OHS development, and the promising pathways for future works are suggested to boost the OHS development in China.

The influence of Ar + SiH4 + O2 plasma formulation on the phase composition and optical properties of amorphous SiOx films with silicon nanoclusters obtained using PECVD with DC discharge modulation was studied. Using a unique technique of ultrasoft X-ray emission spectroscopy, it was found that at a 0.15 mol.% plasma oxygen content, amorphous silicon a-Si films are formed. At a high oxygen content (≥21.5 mol.%), nanocomposite films based on SiOx silicon suboxide containing silicon nanoclusters ncl-Si are formed. It was found that the suboxide matrix consists of a mixture of SiO1.3 and SiO2 phases, and the average oxidation state x in the SiOx suboxide matrix is ~1.5. An increase in the concentration of O2 in the reactor atmosphere from 21.5 to 23 mol.% leads to a decrease in ncl-Si content from 40 to 15% and an increase in the average oxidation state x of SiOx from 1.5 to 1.9. In this case, the suboxide matrix consists of two phases of silicon dioxide SiO2 and non-stoichiometric silicon oxide SiO1.7. Thus, according to the experimental data obtained using USXES, the phase composition of these films in pure form differs in their representation in both random coupling and random mixture models. A decrease in the ncl-Si content of SiOx films is accompanied by a decrease in their sizes from ~3 to ~2 nm and a shift in the photoluminescence band from 1.9 eV to 2.3 eV, respectively.
Short-Term Demand Prediction for On-Demand Food Delivery with Attention-Based Convolutional LSTM
Authors: Yu Xinlian , Lan Ailun , Mao Haijun
Published: September 2023

Demand prediction for on-demand food delivery (ODFD) is of great importance to the operation and transportation resource utilization of ODFD platforms. This paper addresses short-term ODFD demand prediction using an end-to-end deep learning architecture. The problem is formulated as a spatial–temporal prediction. The proposed model is composed of convolutional long short-term memory (ConvLSTM), and convolutional neural network (CNN) units with encoder–decoder structure. Specifically, long short-term memory (LSTM) networks are a type of recurrent neural network capable of learning order dependence in sequence prediction problems. The convolution unit is responsible for capturing spatial attributes, while the LSTM part is adopted to learn temporal attributes. Additionally, an attentional model is designed and integrated to enhance the prediction performance by addressing the spatial variation in demand. The proposed approach is compared to several baseline models using a historical ODFD dataset from Shenzhen, China. Results indicate that the proposed model obtains the highest prediction accuracy by capturing both spatial and temporal correlations with attention information focusing on different parts of the input series.

There is a scarcity of evidence on the levels of pesticide residues among common crops grown in the different regions of the Kingdom of Saudi Arabia (KSA). The present study aims to fill this gap. We collected samples across four regions of KSA (N = 41 from the west, N = 146 from the central, N = 131 from the north and N = 74 samples from the east). Food samples were extracted and cleaned using the modified quick, easy, cheap, effective, rugged and safe (QuEChERS) methodology. Tandem mass (LC-MS/MS and GC-MS/MS) was used to detect pesticide residues. The highest pesticide residue detection rate was 89.7% in the central region, followed by 88.5% in the north, 83.8% in the east and 70.7% in the western region (p = 0.01). Pesticide residue detection rates were significantly higher in fruits than vegetables (p = 0.02). Cypermethrin detection was most common overall, particularly in the Western region (p = 0.002), and pyraclostrobin concentration was the highest among all residues investigated. In conclusion, high detection rates of moderately hazardous pesticide residues were found in various crops across regions in KSA. Routine biomonitoring programs across KSA regions should be implemented, as well as public health campaigns to decrease pesticide residue consumption and exposure.

Authors: Szpot Paweł , Wachełko Olga , Zawadzki Marcin
Published: September 2023

Prostaglandins have stimulative influence on the human uterus and therefore were introduced to medical treatment in reproductive healthcare as labor inductors or abortifacients. The UHPLC-ESI-QqQ-MS/MS method was developed for six prostaglandins: carboprost, cloprostenol, dinoprost (PGF2α), dinoprostone (PGE2), misoprostol and sulprostone (substances for pregnancy termination) in pharmaceutical samples and was applied for the toxicological examination of pills containing misoprostol (collected during gynecological examination). There were used two internal standards: misoprostol-d5 and PGF2α-d4. The quantification of analytes was performed in the MRM mode. The linearity of method was in the range from 0.1 to 10 µg/mL, with a coefficient of determination above 0.997 (R2) for each compound. The precision and accuracy values did not exceed ±5.0%. Analysis of the pills revealed the presence of two substances: misoprostol and diclofenac. Misoprostol and diclofenac dose per sample were as follows: 608.8 ng (sample 1), 708.4 ng (sample 2), 618.8 ng (sample 3) and 67.7 mg (sample 1), 65.3 mg (sample 2) 67.3 mg (sample 3), respectively. A simple, precise and reliable method can be applied for routine examinations in terms of clinical and forensic toxicology examinations as well as in quality control of drugs for pharmaceutical purposes (original drugs and counterfeit medications).

Oncolytic viruses offer a promising approach to tumor treatment. These viruses not only have a direct lytic effect on tumor cells but can also modify the tumor microenvironment and activate antitumor immunity. Due to their high pathogenicity, flaviviruses have often been overlooked as potential antitumor agents. However, with recent advancements in genetic engineering techniques, an extensive history with vaccine strains, and the development of new attenuated vaccine strains, there has been a renewed interest in the Flavivirus genus. Flaviviruses can be genetically modified to express transgenes at acceptable levels, and the stability of such constructs has been greatly improving over the years. The key advantages of flaviviruses include their reproduction cycle occurring entirely within the cytoplasm (avoiding genome integration) and their ability to cross the blood–brain barrier, facilitating the systemic delivery of oncolytics against brain tumors. So far, the direct lytic effects and immunomodulatory activities of many flaviviruses have been widely studied in experimental animal models across various types of tumors. In this review, we delve into the findings of these studies and contemplate the promising potential of flaviviruses in oncolytic therapies.
Appendectomy Mitigates Coxsackievirus B3−Induced Viral Myocarditis
Authors: Niu Chengrui , Xu Wei , Xiong Sidong
Published: September 2023

Appendix has a distinct abundance of lymphatic cells and serves as a reservoir of microbiota which helps to replenish the large intestine with healthy flora. And it is the primary site of IgA induction, which shapes the composition of the intestinal microbiota. Recent population-based cohort studies report that appendectomy is associated with an increased risk of acute myocardial infarction and ischemic heart disease. Here, whether appendectomy has an effect on the occurrence and development of coxsackievirus B3 (CVB3)−induced viral myocarditis is studied. 103 TCID50 CVB3 was inoculated i.p. into appendectomized and sham-operated mice. RNA levels of viral load and pro-inflammatory cytokines in the hearts and the intestine were detected by RT−PCR. Compared to sham-operated mice, appendectomized mice exhibited attenuated cardiac inflammation and improved cardiac function, which is associated with a systemic reduced viral load. Appendectomized mice also displayed a reduction in cardiac neutrophil and macrophage infiltration and pro-inflammatory cytokine production. Mechanistically, we found that CVB3 induced an early and potent IL-10 production in the cecal patch at 2 days post infection. Appendectomy significantly decreased intestinal IL-10 and IL-10+ CD4+ Treg frequency which led to a marked increase in intestinal (primary entry site for CVB3) anti-viral IFN-γ+ CD4+ T and IFN-γ+ CD8+ T response and viral restriction, eventually resulting in improved myocarditis. Our results suggest that appendix modulates cardiac infection and inflammation through regulating intestinal IL-10+ Treg response.

COVID-19 vaccines were developed at an unprecedented speed in history. The factors affecting the response to COVID-19 vaccines are not clear. Herein, the effects of vitamin D and vitamin A (retinol) levels on the response to the BNT162b2 vaccine were explored. A total of 124 vaccine recipients were recruited from the general population attending vaccination centers in Irbid, Jordan. Blood samples were collected immediately before receiving the first vaccine dose (D0) and three weeks later (D21). Baseline (D0) levels of 25-hydroxyvitamin D [25(OH)D], retinol, and SARS-CoV-2 S1 IgG antibodies were measured with ELISA. The response to the BNT162b2 vaccine was tested by measuring the levels and avidity of SARS-CoV-2 S1 IgG antibodies on D21. The participants were divided into two groups, unexposed and exposed, based on the D0 SARS-CoV-2 antibody results. No significant correlation was found between the levels of 25(OH)D or retinol and the levels, avidity, or fold increase of antibodies in both groups. Similarly, no significant difference in antibody response was found between 25(OH)D status groups, retinol status groups, or combined status groups. These findings show that the baseline vitamin D or vitamin A levels have no effect on the short-term response to a single dose of BNT162b2 vaccine.

Even though the COVID-19 vaccine has been available and free of charge to the targeted population in Ethiopia, the vaccination rate was lower than needed to achieve herd immunity at community level. This study aimed to explore community perceptions of COVID-19 and vaccine hesitancy in selected cities of Ethiopia involving 70 in-depth interviews and 28 focused group discussions. The audio-taped data were transcribed verbatim, translated into English, and analyzed using a qualitative content analysis approach using the ATLAS.ti software version 8. The findings revealed that COVID-19 was perceived as evil and caused fear and frustration upon its emergence. The community initially used traditional remedies for its prevention but later transitioned to employing non-pharmaceutical interventions. The primary reasons for vaccine hesitancy were misinformation and misconceptions, such as connecting the vaccine with the mark of the beast, a lack of trust due to the multiple vaccine types, a shorter production timeline resulting in distrust of its effectiveness, and a fear of pain and side effects. Based on our findings, we recommend monitoring the use of social media and countering misinformation with the correct information and continuous public health campaigns. Further studies should be conducted to assess the types and magnitude of impacts from the myths and misconceptions on vaccination uptake.
Некапиталистический способ производства как третий путь развития
Authors:   Православный Свято-Тихоновский гуманитарный университет, Олейников Александр Алексеевич
Published: September 2023

В статье анализируется мирохозяйственная система, в рамках которой фиксируют только два способа производства: капиталистический и социалистический. Основываясь на системном религиозно- философском подходе, автор обосновывает утверждение, что западный капитализм имеет два подтипа: англосаксонский и католический — западноевропейский. Исследование многоукладного общества Востока, основанного на иерархии и соподчиненности множества укладов, показало, что в таком обществе не может установиться господство одного уклада: капиталистического либо социалистического. Речь идет об особой форме общинного коллективистского «восточного капитализма». Это и есть третий путь общественного развития.

Published: September 2023

La representatividad en el sistema democrático ecuatoriano, surge del fenómeno evidenciado en los últimos procesos electorales, la diminuta votación con la que llegaron a su curul muchos dignatarios afectaría la legitimidad en sus cargos, lo que a su vez deja latente la posibilidad que luego del año de funciones sean sujetos de mecanismos como el de revocatoria del mandato. El objetivo del estudio es analizar la falta de representativa en las dignidades de elección popular según lo expresado en la Constitución de la República del Ecuador. Para ello, se empleó la metodología exploratoria, descriptiva, analítica, y, sintética. Como resultado se evidencia que, la democracia en Ecuador representa un sistema político, una forma de Estado, pero, por otro lado, se identifica como una forma de vida civil y social. Para finalizar existen inconsistencias que son evidenciadas post – elección y que hasta la actualidad han quedado inconclusas, en revisión o anuladas, por falta de aplicación del principio de legalidad e imparcialidad emanados de la Constitución de la República.

The application of discretion is the policy of the office that essentially allows public officials (including the police) to carry out policies that violate the law, on three conditions, namely in the public interest, still within the limits of their jurisdiction, and do not violate the General Principles of Good Government. Data analysis is done qualitatively by collecting primary, secondary and tertiary legal materials related to research. The results of the analysis obtained are: the concept of police discretion as a law enforcement officer in the future in democratic policing is characterized by reforms from within the police body itself, namely through structural aspects, instrumental aspects and cultural aspects. The existing laws and regulations in the regulation of the performance of the State Police of the Republic of Indonesia, especially in the discussion of discretion, are adequate and there is no overlap between one law and another. It takes understanding of the police in interpreting and applying the provisions of existing rules so as not to become a negative assessment in the community due to improper abuse of police authority in the implementation of discretionary resolving cases. That it required oversight both internally and externally of police performance both personally and in groups. It can also be by improving the quality of police resources by means of formal education or training so as to build a responsible attitude to maintain the image of the police in the community and in accordance with the assessment of the Code of Ethics of the State Police of the Republic of Indonesia.

One of the risk mitigation instruments which mostly used by banks in providing Subsidized/Sejahtera mortgage facilities is the Guarantee Agreement. The Guarantee Agreement is commonly known as the Buy Back Guarantee Agreement or the Guarantee Agreement to Buy Back. This agreement is not only contained in Cooperation Agreement clause between bank and developer, it is also stated in the form of a deed in the form of a Buy Back Guarantee Agreement or a guarantee deed to buy back the object of the house collateral by guarantor or insurer. Buy Back Guarantee agreement as an alternative for loan guarantees, namely the provision of guarantees and transfer of right to developers to buy back home guarantees from debtors who experience non-performing loan with the condition of the Land Title Certificates not being complete or solving certificates on process, the legal correlation between developer and debtor is still in the form of a Sale Binding Agreement and/or Mortgage Certificate has not yet been issued. However, in practice, the implementation of the Buy Back Guarantee still encounters many obstacles, either form developer, debtor, and bank side.

The research employs normative juridical method, namely the method which is based on applicable legal norms sourced from secondary data consisting of primary, secondary, and tertiary legal materials. Aside of that, to complete the research, the author collect the data from interview of related sources, such as the Banking/Creditor, the Subsidized Housing Developer, and the Notary/Land Deed Maker (PPAT).

From the research results it is found that the legal force of the Buy Back Guarantee Agreement as an alternative for non-performing loan settlement in KPR Sejahtera financing does not have executive power as the guarantee deeds that have been regulated and used at guarantee institution. The implementation/execution of the Buy Back Guarantee by the developer in accordance with the agreed agreement must be carried out since the developer receives a notification/request letter from the bank, but in practice, developer almost never carry out buy back on the house collateral directly. The obstacle in implementing the Buy Back Guarantee Agreement in KPR Sejahtera financing are from the developers, debtors, and banks themselves.

The world is now starting the trend of going green or back to nature. The slogan goes green or back to nature can also be interpreted as living in harmony with nature. Our beloved country of Indonesia has implemented a harmonious life with nature, we can find it in the Javanese planting season calendar called Pranata Mangsa. In the pranata mangsa, we are taught the method of living in harmony, especially in an agricultural system. Harmony with nature means harmony between seasons, weather, living things, and types of plants. If everything is applied, there will be harmonization between all elements both from outside and inside so that additional elements such as chemical fertilizers and pesticides in agriculture, which essentially eliminate the harmonization of nature itself, are not needed. The implementation of Finite State Automata on the farming season calendar is expected to be able to educate and make it easier for farmers in particular and the Indonesian people, in general, to able to recognize the farming time and apply it to daily life. The final result of this research is the calendar system that can convert the date and month in the masehi calendar into the period or season of the pranata mangsa system.

PT. Selaras Hutama Mandiri (SHM) needs to analyze the readiness of Customer Relationship Management users with the aim of preventing failures during the implementation process which will have an impact on the company's business processes. By looking at the existing Human Resources, they are still unfamiliar with the use of technology, so it is feared that the technology to be adapted cannot be used by existing human resources. The method used is the Technology Readiness Index which refers to the tendency of users to adopt and use new technology in the work environment with the variables Optimism, Innovation, Discomfort and Insecurity. The results obtained that the independent variable that has an influence on the readiness of Customer Relationship Management users in operating or using Customer Relationship Management is the innovation variable with a value of sig .001 < from probability 0.05 and the t test has t count > t table, namely 5.916 < 2.365. Other independent variables Optimism, Discomfort and Insecurity did not affect users in operating or using Customer Relationship Management. Meanwhile, the independent variable simultaneously influences the dependent variable on the readiness of the Customer Relationship Management (Technology Readiness) users. So that the company' s concerns with the readiness and ability of employees to use technology can be overcome by an analysis using the Technology Readiness Index method that they are ready to use Customer Relationship Management. It is very important to analyze user readiness so that the technology applied to the company's business processes can be appropriate, meaning that technology implementation is not only a trend but in accordance with company needs.

Electric power plants always use fossil fuels such as coal, oil, etc. However, the fossil fuel supply in Indonesia is decreasing from year to year. This causes power plants to be powered by using fuels that will not run out, such as solar Energy, water, wind, and others. Solar Energy, water, wind, and others are Alternative Energy or can also be called New and Renewable Energy. To guarantee a power plant powered by alternative Energy, it must be analyzed regarding the growth of new and renewable Energy. The method used in analyzing the development of new and renewable Energy is the Adaptive Neuro Fuzzy Inference System Method.
MW or 0.599%. This result has increased yearly in Indonesia's new and renewable energy growth.

Stroke is a severe health problem and can significantly impact a person's quality of life. Therefore, it is crucial to predict stroke early so that preventive measures can be taken before it is too late. This study demonstrates the importance of hyper tuning and hyperparameters in a stroke prediction model. Literature studies show that many studies on stroke prediction need to explain this, even though this is very important for developing the performance of stroke prediction models. In this study, we use the Support Vector Machine (SVM) algorithm to predict stroke and evaluate the algorithm's performance without hyper tuning and with hyper tuning Randomized Search CV. We also divide the data into training and test data by 75% and 25%. The results of this study indicate that hyper-tuning can improve the accuracy of the stroke prediction algorithm. The algorithm's accuracy is 77% without hyper-tuning, whereas, with hyper-tuning, the accuracy increases to 96%. Hypertuning with the Randomized Search CV method can improve the performance of the stroke prediction algorithm and is very important to do in developing predictive models.
Que savons-nous de la croissance et du développement du cerveau des humains préhistoriques ?
Authors: Balzeau Antoine
Published: September 2023

La paléoneurologie est un domaine complexe et l’étude de la croissance cérébrale chez les espèces humaines fossiles n’en est qu’à ses premiers pas. Le registre fossile disponible est parsemé, incomplet, sujet à interprétation. Il est aussi difficile d’estimer l’âge individuel des spécimens fossiles qui jalonnent notre histoire. Enfin, la forme globale de la boîte crânienne et son volume ne font pas tout, il faut chercher à documenter les variations des détails de la surface cérébrale. Il est ainsi indispensable de se pencher sur les petites traces laissées par le cerveau, en documentant sillons, lobes et aires cérébrales sur l’endocrâne, ainsi que leurs possibles changements au cours du temps. Ce texte récapitule ce que nous savons de la croissance et du développement du cerveau chez nos ancêtres préhistoriques, entre Australopithèques, Homo erectus et Néandertaliens. Les premiers résultats montrent combien le cerveau a varié au sein de l’humanité, que les changements entre les plus jeunes et les adultes au sein de chaque espèce sont autant de réponses diversifiées qu’il nous reste à documenter et à comprendre.
Mémoire autobiographique et appartenance culturelle
Authors: Oulahal Rachid
Published: September 2023

Autobiographical Memory and Cultural Background. The autobiographical memory stores memories of personally lived experiences but, beyond this sole conservation, it ensures an active role in elaborating the life history continuity and maintaining an identity coherence. We propose in this article to present a literature review of recent and ongoing researches on the link between autobiographical memory and individuals’ cultural affiliations. Researches in cross-cultural psychology have identified a significant relationship between the subject''s cultural environment and different characteristics of the autobiographical memory. In the field of intercultural psychology in which our research background sits, and which postulates a link between culture and psyche, researchers have identified the cultural contact as a source of identity questioning and redefining for any individual who experiences it. Thus, while the concept of autobiographical memory is strongly correlated with the concept of identity, we believe that a field of research becomes relevant to the analysis of the autobiographical memory in intercultural situations, which to our knowledge has not yet been addressed.

Published: September 2023

Giriş: Hipertansiyon hastalarında kan basıncının kontrol altına alınmasında aleksitiminin yönetilmesi ve öz etkililiğin değerlendirilmesi önemlidir.
Amaç: Bu çalışmadaki amaç hipertansiyon hastalarının tanımlayıcı özelliklerinin ve aleksitimi düzeylerinin öz etkililik düzeylerinin yordayıcısı olup olmadığını belirlemektir.
Yöntem: Bu araştırma nicel araştırma yönteminin korelasyon desenine göre yapıldı. Araştırmanın verileri Aralık 2022-Mayıs 2023 tarihleri arasında toplandı. Araştırmanın evrenini Türkiye’de yaşayan hipertansiyonlu hastalar oluşturdu ve çalışmaya toplam 103 hipertansiyon hastası katıldı. Araştırmanın verileri “Hasta Tanılama Formu”, “Toronto Aleksitimi Ölçeği” ve “Hipertansiyon Öz-Etkililik Ölçeği” ile toplandı. Veriler bağımsız örneklem t testi, pearson korelasyon ve çoklu linear regresyon analizi ile değerlendirildi.
Bulgular: Yaş ortalaması 45.37 ± 17.03 olan hipertansiyon hastalarının %63.1’inin kadın olduğu belirlendi. Hastaların öz-etkililikleri ile aleksitimi düzeyleri arasında istatistiksel olarak anlamlı bir ilişki bulunmadı (r = -0.071, p > .05). Aleksitiminin dışa-dönük düşünme alt boyutu, yaş, ailede hipertansiyon varlığı ve ilaçları düzenli kullanma bağımsız değişkenlerinin hastaların öz-etkililik düzeyleri üzerindeki varyansın %22.7’sini açıkladığı görüldü.
Sonuç: Hastaların öz-etkililiği ile aleksitimi düzeyleri arasında ilişki olmadığı görüldü. Aleksitiminin dışa-dönük düşünme alt boyutu, yaş, ailede hipertansiyon varlığı ve ilaçları düzenli kullanma değişkenlerinin hipertansiyon hastalarının öz etkililik düzeylerini yordadığı bulundu. Hastaların öz-etkililiği ile aleksitimi düzeyleri arasında ilişkiyi ve yordayıcı değişkenleri inceleyen daha kapsamlı çalışmaların yapılması önerilir.

Abstract: Background: Nowadays, transplantation is the only effective method for saving human lives when organs fail. Its choice in clinical practice encounters numerous barriers along the way, related to religious, ethical, social, and moral considerations. Nowadays, there are many changes in the hierarchy of values of young adults, and it is therefore important to analyse their impact on the perception of socio-cultural processes, including transplantation. Aim of the study: To analyse values and their influence on attitudes towards organ transplantation among students at Lublin universities. Material and methods: The study was conducted using a diagnostic survey method, with a survey technique. A self-administered survey questionnaire and a standardised tool List of Personal Values (Lista wartości osobistych, LWO), bearing a label were used. The study involved 205 respondents studying at three universities in Lublin (Medical University, Catholic University of Lublin, Maria Curie–Skłodowska University). Statistical analyses were performed using the SPSS Statistics package. Relationships between attitudes towards transplantation and sociodemographic variables and values were analysed using Kruskal-Wallis H tests and Spearman’s rho correlation coefficient. A graphical presentation of the results was made using summary tables and bar charts. Results and conclusions: Hierarchy of personal values has no influence on attitudes towards transplantation. Age, gender, type of university and religion are not related to students’ attitudes towards the transplant procedure. There are correlations between place of residence and attitude towards religious practice and students’ attitudes towards transplantation.
