Comparative data on usage effectiveness of quarry and modified diatomite additives of Sharlovsky deposit of Ulyanovsk region in dairy cattle breeding are given. Assessment of parametres of physiological and biochemical status and milk productivity of Holstein cows in case of application of additives is given. The experiments were carried out on 150 cows on the basis of SPK Kolkhoz named after Kalinin, Ulyanovsk Region. The experimental groups of cows were selected by the method of analogues, taking into account age, breed, live weight and physiological state. Before start of the experiment, animal clinical condition was studied. Three groups of 50 cows were formed for scientific and economic experiment and 10 cows for physiological test. Feeding was carried out with diatomite introduction according to the following scheme: the 1st group (control) received only the farm ration (FR), the 2nd group - FR and the addition of modified diatomite at a dose of 300 g/animal/day, the 3rd group - FR and addition of quarry diatomite from the same deposit and in the same amount. The housing conditions of cows in the groups were equal. Milk productivity was recorded according to control milkings. Total duration of the experiment was 90 days. Positive results were obtained, which prove that introduction of modified and quarry diatomite supplements from Sharlovsky deposit of Ulyanovsk region into rations of Holstein cows is effective. Improvement in physiological and biochemical status and protective mechanisms of the body of cows was established. An increase of their average daily milk yield and improvement in its quality were noted when using the tested additives.

The purpose of the study is a search for local cheap sources of biophilic plant nutritional elements and a possibility of production of organomineral fertilizers based on them, which are agronomically effective, environmentally safe and economically feasible. To achieve this goal, field experiments were carried out on the basis of the experimental field of Ulyanovsk State Agrarian University named after P.A. Stolypin and SPK Kolkhoz named after Kalinin, Veshkaimsky district, Ulyanovsk region. The effectiveness of diatomite from Inza deposit and zeolite from the Maina deposit of Ulyanovsk region were studied in field experiments as fertilizers for vegetable crops and millet in pure form, as well as in combination with poultry manure. All experiments were conducted with strict compliance with methodological requirements; analyzes of soil and plant samples were carried out in accordance with relevant state standards. It was found that, high-siliceous rocks such as diatomite and zeolite are of great interest in Ulyanovsk region as sources of plant nutrients, and poultry manure is important agricultural waste. Studies showed that diatomite and zeolite significantly improve soil nutritional regime. Thus, introduction of diatomite into the soil as a fertilizer of millet at a dose of 3 t/ha led to an increase of mineral nitrogen in the arable layer of leached black soil by 1.9 mg/kg, available phosphorus by 7 mg, and potassium by 12 mg/kg of soil. Improvement of soil nutritional regime with introduction of siliceous rocks influenced millet yield: in case of diatomite application at a dose of 3 t/ha, the yield increase was 0.82 t/ha; zeolite at a dose of 0.5 t/ha - 0.33 t/ha ( 13 %). The effectiveness of siliceous rocks increased significantly when combined with poultry manure. Yield of cucumbers increased by 6.8 t/ha, tomatoes by 0.4 t/ha, carrots by 4.9 t/ha, table beetroot by 8.1 t/ha in case of diatomite application in combination with poultry manure compared to variant of its application in pure form.

The studies were carried out on the basis of the laboratory of breeding technologies of the Federal State Budgetary Scientific Institution "Federal Scientific Center of Bast Crops" (Tver region) in 2019-2021. The purpose of the research is to study selection effectiveness of fiber flax plants for a new trait - height at various seeding amounts in the selection nursery. It was established that initial testing with subsequent removal of plants that were not included in the interval of typical height (± 10% of the average value) allowed to ensure a higher uniformity of typical plants in terms of fiber content compared to the control in the stalk, when sowing 200 viable seeds per meter of row in the selection nursery, the highest yield of renewed seed material (91.8 g/m²), it also allowed to reduce labor costs. Studies showed that selection of fiber flax plants by height provided an increase of seeding energy in case of sowing of 150 and 200 viable seeds by 14-15%, seed strength by 20.8-27.3%, and 1 cm of seed germination by 7.0 - 21.4% compared with the control variant. However, the studied methods of plant selection did not affect mass formation of 1000 seeds. According to soil control data, when testing plants for a new trait, their high uniformity was achieved in terms of the main varietal trait - fiber content in the stem, which was characterized by variation coefficient at a level of 3.0-3.5% with 3.0-3.1% in control. A good evenness of plants was also revealed by another varietal trait - height. Variation coefficient for this trait was 4.3-5.5%. The effectiveness of selection method of fiber flax plants by a new trait-height is confirmed by the results of its verification. When checking the method, the cost reduction for work performance on selection and testing of plants by height amounted to 27% compared to the control.

Authors: Yadav Avnesh , Khurana Tina , Nagpal Vijay Kumar , Kaur Mohandeep
Published: April 2023

Background: Pre-oxygenation before induction of general anaesthesia is widely used for enhancing oxygen reserves and preventing hypoxia. Several techniques for pre-oxygenation have been described. This study was designed to compare the PaO2   and ETO2 with single vital capacity breath technique (SVCB) and tidal volume breathing technique (TVB) for adult patients undergoing general anaesthesia.
Methods: Fifty patients were pre-oxygenated with both techniques - first SVCB then TVB separated by five minutes of breathing room air or till ETO2 & PaO2 values reached baseline values (whichever was later). ABG samples & ETO2 readings were taken before pre-oxygenation & every thirty seconds for three minutes in both techniques.
Results: Pre-test, mean PaO2 and ETO2 values of both techniques (SVCB and TVB) were similar. In SVCB technique, the mean PaO2 (mmHg) and ETO2 (%) significantly increased at 30 seconds (p ≤ 0.001) from 95.26 and 17.14 (pre-test time) to 304.34 and 92.48 respectively. In TVB technique, an exponential increase was noted. The mean PaO2 (mmHg) and ETO2(%) significantly increased at 180 seconds (p ≤ 0.001) from 96.26 and 16.26 (pre-test time) to 305.64 and 93.08 respectively. Peak values of oxygenation in both groups were similar but achieved at different time points.
Conclusion: SVCB technique achieves high oxygenation rapidly but is not sustained thus can be used for rapid sequence induction though not recommended for difficult airway scenarios. TVB technique also achieves high oxygenation but steadily. TVB may be used for induction, including, rapid sequence induction but after 3-5 minutes of pre-oxygenation.

Authors: Trivedi Virali , Verma Indu , Garg Pankaj
Published: April 2023

Background: Monitoring the depth of Anesthesia using Entropy modality is essential and resourceful as it allows for more accurate hypnotic drug administration and decreased anesthetic drug consumption and shortens the recovery time. This study was performed to evaluate the effect of entropy monitoring on Sevoflurane consumption in patients undergoing Off Pump Coronary Artery Bypass Graft Surgery.
Methods: A total of 60 patients of ages between 40 – 70 years and of either sex with American Society of Anesthesiologist (ASA) grade 2 and 3, planned for Off Pump Coronary Artery Bypass Graft Surgery were randomly allocated to two groups in this Randomized Controlled Trial. In the control group i.e. Group B, Sevoflurane was titrated according to changes in clinical parameters (Heart Rate (HR) and Blood Pressure (BP) changes within 20% of baseline values) and in the study group i.e. Group A, Sevoflurane was titrated to maintain State Entropy (SE) values between 40-60 accordingly. Response Entropy (RE) and State Entropy (SE) values were continuously recorded in both the groups but were displayed on the monitor only in the study group and were not displayed to the anesthesiologist in the control group. The entropy values, Sevoflurane Consumption and recovery times were compared amongst the two groups. Patients in both the groups were ventilated on Volume Control Mode of ventilator with 100% oxygen @ 2L/min.
Results: There were no significant results in terms of age, sex, ASA Grade and NYHA Grade amongst the two groups. Sevoflurane consumption and time of recovery were significantly reduced in the study group i.e. Group A than the Control group i.e. Group B (p value <0.001; Sevoflurane consumption: 7.03±0.67 ml/hr vs 12.42±0.68 ml/hr; Recovery Time 6.47±0.65 hr vs 12.05±1.11 hr). Response and State Entropy values were lower in the control group than the study group (p < 0.001) during the maintenance phase of anesthesia. Systolic Blood Pressure values during skin incision, sternotomy and at the time of completion of all grafts were significantly lower in study group as compared to the control group.
Conclusion: Monitoring the Depth of Anesthesia using Entropy Monitoring leads to significant reduction in Sevoflurane consumption and significant faster recovery rate from surgery.

Published: April 2023

Background: The term "outpatient surgery" has become a common procedure in most hospitals around the world. On other hand, Spinal aesthesia can mimic the outcome sought by the principle of outpatient surgeries since it takes a short time to recover and limits the need for post-operative pain medication Therefore, the objective of this study is to focus on finding a method to reduce the side effects that commonly accompany the procedure of spinal aesthesia and to avoid the possible hemodynamic changes that may occur.
Methods: The method for the study will be a narrative review of various medical journals, conferences papers, and unpublished documents using the dual keywords, outpatient surgeries spinal aesthesia, and ambulatory aesthesia, we include in this research thirty-one original articles, fifty-three reviews articles, two books, three handbooks, and two guidelines searched in the deferent database (google scholar, Research gate, pub med, science direct).
Results: Consideration should be given to the quality of patients who participate in outpatient concepts. Finally, in terms of cost, side effects, and patient satisfaction, the spinal aesthetic approach gives a favourable outcome since it covers post-operative time without the need for analgesia and reduces the percentage of postoperative nausea and vomiting, and reduces the time staying in the hospital.
Conclusions: In conclusion, the study discovered that a major proportion of surgeries performed over our lifetimes are outpatient procedures. Therefore, Discharge criteria should be posed with one precise criterion. There is no standard protocol to serve these types of surgeries and patients. The only criteria found and practiced served general conditions for outpatients and inpatients. There have been several attempts to create a protocol that can meet the pleasing outcome of outpatient surgeries. Consequently, we need more research to cover this lack and serve the Genuine needs of a protocol to define the criteria and categories that concern the term outpatient and outpatient surgeries and lead to improving the quality of outpatient surgeries with fewer side effects and minimum hemodynamic changes.

Introduction: Postoperative pain following laparoscopic cholecystectomy is common in abdominal surgeries. Opioids and non-steroidal anti-inflammatory drugs are used in the management of postoperative pain. The current clinical study was undertaken to evaluate the efficacy of a preemptive diclofenac suppository for the alleviation of post-surgery pain and opioid consumption in laparoscopic cholecystectomy patients.
Methods: A total of eighty patients aged 18 to 65 who underwent laparoscopic cholecystectomy in Sina Hospital of Maragheh University of Medical Sciences were included in this prospective, matched case-control study and were randomly allocated to two groups of 40 each. Subjects received 100 mg diclofenac suppository or placebo within 2 h before surgery. The pain score and analgesic consumption data were recorded up to 24 h postoperatively. An Independent t-test was utilized for the analysis of results.
Results: Visual Analogue Scale (VAS) scores in the diclofenac group were statistically lower at 2, 4, 8, and 12 hours compared to the placebo-controlled group. Opioid consumption was statistically significantly reduced in the treatment group compared to the control group (20.0 ± 3.48 vs 54.7 ± 3.63 ml, respectively. Rescue analgesia usage was significantly higher in the control group. Half of the patients in the diclofenac group did not need any opioid drug. Besides, postoperative side effects and hospital staying duration were decreased in the diclofenac group in comparison to the control group.
Conclusion: Current study demonstrates that preemptive diclofenac 100 mg administration could be taken into consideration to alleviate postoperative pain and is a valuable addition to the standard treatment following cholecystectomy pain management.

Authors: Grigory A Demyashkin , Matvey A Vadyukhin , Vladimir I Shekin
Published: April 2023

Background: At present, the damage of male reproductive function caused by electron irradiation, as well as the development of methods for its correction are the relevant topics for further research. In fact, the effect of leukocyte-poor platelet-rich plasma (LP-PRP) growth factors are poorly investigated on different aspects of male fertility.
Methods: In this study, Wistar rats were divided into four groups; I) control which were injected with saline; II and III) groups (n=65) whose testes were locally irradiated with electrons to a dose of 2 Gy (linear accelerator "NOVAC-11"); III) the group (n=30) which received LP-PRP for 11 weeks after irradiation; and IV)­ animals (n=30) which received only LP-PRP (conditional control). The testes were studied by histological, immunohistochemical (IHC), western blotting, and TUNEL methods using Ki-67, Bcl-2, and p53. Comparison between groups was performed and p<0.01 was set as the level of significance.
Results: The results showed a decrease in the expression levels of Ki-67 and Bcl-2 besides an increase in p53-positive cells by the end of the experiment (p<0.01). After injection of LP-PRP, a gradual restoration of the proliferative activity of gametes was noted, which was confirmed by an increase in the proportion of Ki-67- and Bcl-2-positive germ cells (46.4±2.3, p<0.01 and 23.5±1.1, respectively, p<0.01).
Conclusion: Ki-67 expression and TUNEL analysis in the testes revealed a modulation of the proliferative-apoptotic balance towards apoptosis of germ cells after 2 Gy local electron irradiation. A tendency to restore the proliferative-apoptotic balance was noted after LP-PRP injections as indicated by increase in Ki-67-positive germ cells.

Background: Amniotic fluid in the uterus is beneficial for the fetus growth and protection due to its nutritional elements as well as its antibacterial and anti-inflammato-ry properties. Today, body membranes are increasingly being used in multiple fields. The purpose of the current study was evaluation of the antibacterial effects of amniotic fluid and comparison of its effects on pathogenic and probiotic bacteria.
Methods: This experimental study was conducted on amniotic fluid obtained from 43 healthy mothers who gave birth by selective cesarean section. Then, antibacterial effects of amniotic fluids were investigated on 8 standard bacterial strains, including Bacillus cereus, Escherichia coli, Staphylococcus aureus, Shigella flexneri, Pseudomonas aeruginosa, Klebsiella pneumoniae, Bacillus cereus, and Lactobacillus plantarum by agar well-diffusion method. Data analysis was performed by SPSS software, vs. 22 (IBM, US).
Results: Amniotic fluid revealed an inhibitory effect on the growth of bacterial strains. Staphylococcus aureus and Streptococcus pyogenes strains showed growth inhibition in 39% and 17% of samples, respectively. In other bacterial strains, there was growth inhibition in less than 5% of the samples. Also, the zone of growth inhibition for Staphylococcus aureus and Streptococcus pyogenes was significantly higher than the other strains. Amniotic fluid samples had an antibacterial effect on all pathogen strains in general, but not on the Lactobacillus plantarum probiotic strain.
Conclusion: Our findings suggest that the antibacterial effect of amniotic fluid on pathogenic bacteria is significantly higher than the Lactobacillus plantarum as a probiotic one. Overall, the findings support the use of natural substances as alternative therapeutic agents to combat antibiotic resistance.

Background: The purpose of the current study was to evaluate patient-oriented strategies encompassing individualized oocyte number (POSEIDON) criteria, validate stratification of low prognosis women, and prognosticate their reproductive potential in terms of cumulative live birth rate (CLBR) in Indian women.
Methods: Out of 4048 women who underwent IVF/ICSI, 3287 women met the criteria for final evaluation of CLBR. They criteria were divided into (a) group 1a as cases with <4 oocytes retrieved and 1b with 4-9 oocytes retrieved; (b) group 2a as cases with <4 oocytes retrieved and 2b with 4-9 oocytes retrieved; (c) group 3 (<35 years, AMH <1.2 ng/ml, AFC <5); and (d) group 4 (≥35 years, AMH <1.2 ng/ml, AFC <5). Non-POSEIDON group was sub-divided into normo-responders (10-20 oocytes) and hyper-responder (>20 oocytes).
Results: Overall CLBR was two-fold lower in POSEIDON group as compared to non-POSEIDON group (p<0.001). For every one-year increase in the age, the odds of CLBR decreased by 4% (OR 0.96, CI 0.93-0.99) in POSEIDON group and by 5% (OR 0.95, CI 0.92-0.98) in non-POSEIDON group. For every unit increase in number of oocytes retrieved, the odds of CLBR increased by 1.22 times (OR1.22, CI 1.16-1.28) in POSEIDON group and by 1.08 times (OR 1.08, CI 1.05-1.11) in non-POSEIDON group. Among POSEIDON groups, the highest values in CLBR belonged to group 1b followed by 3, 2b, 4, 1a, and 2a.
Conclusion: POSEIDON stratification of low-prognosis women undergoing IVF may be considered valid to prognosticate and counsel women undergoing IVF. Prospective studies will strengthen its validity among different ethnic populations.

Authors: Javedani Masroor Mojgan , Younesi Asl Ladan , Sarchami Niloufar
Published: April 2023

Background: The relationship between uterine peristalsis before embryo transfer and the success of assisted reproductive techniques (ARTs) has not been properly investigated. In this study, the effect of uterine contractions on embryo implantation in frozen embryo transfer (FET) cycles was investigated to determine whether the frequency of uterine contractions can be used as a quantitative marker to assess endometrial receptivity.
Methods: In this cohort study of 68 eligible FET candidates, one hour before embryo transfer (ET), frequency of uterine contractions was assessed with transvaginal ultrasonography. Patients were followed up for 20 weeks. The association between FET outcomes including clinical pregnancy, abortion, and ectopic pregnancy with uterine contractions was evaluated. Binary logistic regression was conducted to test the association between clinical pregnancy outcomes in different groups. The p<0.05 were considered statistically significant.
Results: Of 68 patients, 25 (36.8%) experienced clinical pregnancy. Multiple logistic regression for omitted confounders (age, BMI, duration, type and cause of infertility) revealed that patients with uterine peristaltic wave frequency less than 2≤ wave/min had higher chance of successful pregnancy compared to those with ≥4 wave/min (odds ratio: 10.8; 95% confidence interval: 1.5-79.4, p=0.019). The Pearson's correlation showed a statistically significant relationship between the frequency of uterine contraction and endometrial thickness (r= 0.42, p=0.002).
Conclusion: Patients with uterine peristalsis of <4.0 wave/min before embryo transfer had a higher chance of successful implantation and pregnancy compared with those with higher contraction frequencies. It seems that measuring uterine contraction frequency before embryo transfer might help to predict pregnancy outcomes.

Authors: Gamarra Antes Diego
Published: April 2023

La existencia de razonables disensos respecto del alcance de formulaciones constitucionales abstractas sobre derechos, incluso coincidiendo en su concepción como mínimos determinantes de dignidad que merecen especial protección, exige seguir pensando en ajustes institucionales para dotar de mayor legitimidad democrática a las decisiones relativas a su especificación. Así, en la línea de aceptación de una versión débil de constitucionalismo y de un control jurisdiccional de constitucionalidad de las leyes concebido como una locución en un diálogo: (a) se presentan y exploran preliminarmente alternativas de mejora democrática en la propia configuración del control jurisdiccional de constitucionalidad, y (b) se propone un modelo de evaluación legislativa y eventual respuesta constitucional, estructurada bajo un proceso especialmente democrático, que potencie la deliberación política robusta y contemple la participación de la ciudadanía.

La falta de claridad conceptual frente a criptoactivos y criptomonedas y sus repercusiones jurídicas en Colombia: un estudio de caso
Authors: Almeyda Orozco Nicolás
Published: April 2023

El presente artículo busca poner en conocimiento la problemática que se presenta al no existir una definición concreta de lo que se entiende por “criptomoneda” y “criptoactivo”, y las repercusiones jurídicas que ello puede traer al momento de buscar una intervención regulatoria respecto de dicha figura. El artículo hace una comparación desde sus elementos entre moneda y “criptomoneda”, y se muestran los problemas de la indefinición de la figura teniendo como base los proyectos legislativos que han sido tramitados ante el Congreso de la República de Colombia.

Prezentowany artykuł omawia zagadnienia dotyczące technologii zaczynów cementowych proponowanych do uszczelniania kolumn rur okładzinowych w podziemnych magazynach wodoru w sczerpanych złożach węglowodorów. Do badań laboratoryjnych wytypowano dziesięć receptur zaczynów zawierających różne dodatki i domieszki (m.in. nanomateriały, tj. nano-SiO2, nano-Al2O3, lateksy, polimery wielkocząsteczkowe). Badania receptur prowadzono w temperaturze 60°C pod ciśnieniem 25 MPa, stosując w składach zaczynów domieszkę odpieniającą, upłynniającą, antyfiltracyjną oraz opóźniacz wiązania. Badania wykonywano na dwóch rodzajach cementów: portlandzkim CEM I 42,5 oraz wiertniczym klasy G. Określano parametry technologiczne świeżych i stwardniałych zaczynów cementowych, badając: gęstość, odstój wody (wolną wodę), reologię, czasy gęstnienia, a także wytrzymałość na ściskanie, porowatość oraz szczelność rdzeni cementowych względem wodoru. Płynne zaczyny cementowe posiadały prawidłowe parametry technologiczne (były dobrze przetłaczalne w warunkach HPHT, a ich gęstości wynosiły 1,80–1,91 g/cm3). Wytrzymałości na ściskanie stwardniałych zaczynów cementowych po okresie od 2 dni do 28 dni hydratacji, zwłaszcza w przypadku próbek z dodatkiem nanokomponentów, przyjmowały bardzo wysokie wartości (po 28 dniach przekraczając 40 MPa). Próbki kamieni cementowych posiadały bardzo niską zawartość porów kapilarnych, co ogranicza możliwość tworzenia się kanalików w płaszczu cementowym otworu wiertniczego. W większości próbek pory o najmniejszych rozmiarach (poniżej 100 nm) stanowiły zdecydowaną większość (powyżej 95–97%) ogólnej ilości porów występujących w matrycy cementowej. Najkorzystniejsze parametry technologiczne uzyskano w przypadku próbek zawierających nano-SiO2 (nanokrzemionkę), a optymalny współczynnik wodno-cementowy dla takich zaczynów kształtował się na poziomie około 0,46–0,48 – w zależności od rodzaju zastosowanego cementu. Najniższe wartości przenikalności dla wodoru zanotowano dla receptur zawierających nanokrzemionkę (nano-SiO2). Receptury o najlepszych parametrach technologicznych, zawierające nanokomponenty (po wykonaniu szczegółowych testów), będą mogły znaleźć zastosowanie podczas uszczelniania rur okładzinowych w otworach wierconych w celu magazynowania wodoru.
Hibridnost pravnega normiranja v Evropski uniji : Pravni in institucionalni vidiki uporabe mehkega prava in pojav hibridnih pravnih področij
Authors: Rošic Feguš Verena
Published: April 2023

Normativno okolje EU je postalo dinamičen regulativni okvir, v katerem normativno raznoliki pravni akti, sprejeti v posledici medsebojno različnih postopkov odločanja, postajajo vse pomembnejši, tradicionalna zakonodajna metoda EU pa kljub ohranjanju svoje osrednjosti, izgublja kot izključen način pravnega reguliranja. Zaradi sence hierarhije, ki jo zavezujoče pravo nudi mehkemu pravu, kadar se »prošnja« mehkega prava za upoštevanje izjalovi, prihaja do »prostovoljne prisile« in kreativnega pravotvorja: inter alia ob obstoju specifičnih okoliščin mehko uporablja mehanizme izvrševanja identične mehanizmu izvrševanja zavezujočega prava, zato v končnem rezultatu razlike za države članice glede na naravo uporabljenega prava ni. Po empirični raziskavi treh pravnih področij knjiga ponuja ugotovitve o hibridnosti pravnega normiranja v EU, kjer sooobstoj mehkega in zavezujočega prava tvori hibridna pravna področja, na katerih je vloga mehkega prava spremenljivka predpogojena s politično konfliktnostjo področja ter odvisna od razlikovalnega kriterija vrste pristojnosti EU, predlaga pa tudi vpeljavo minimalnih procesnih standardov za zagotovitev demokratične legitimnosti.
Application of computer technologoies in teaching a foreign language
Authors: BOLİBEKOVA Mavjuda
Published: April 2023

The article is devoted to the issue of using various computer technologies in teaching a foreign language. The advantages and disadvantages of modern computer technologies are characterized; describes the experience of using computer technology in the process of teaching a foreign language to students of natural sciences. Recently, there has been a tendency to reduce the interest of students of higher educational institutions in foreign language classes. Traditional forms of education drastically lag behind the modern perception of information: students study the necessary material abstractly, preferring to furtively browse the news on social networks during class. In the process of traditional education, students often do not have the opportunity to realize their needs for self-expression, self-knowledge. The practical lesson is aimed mainly at the passive assimilation of the material offered by the teacher, memorizing the rules, without the abilities, inclinations, and interests of students. We believe that in the modern educational process it is necessary to apply interesting, non-standard forms of education, which, in our opinion, will allow us to return students' lost interest in learning a foreign language. The teacher needs to move away from the standard practical lesson to some extent, introduce something new into it that could attract attention, activate students’ activity encourage them to act, think and search.
El proyecto de la libertad según Axel Honneth
Authors: Cortés Francisco
Published: April 2023

En este artículo argumento que, aunque Honneth desarrolla, en El derecho de la libertad, una teoría de la justicia y la libertad de más alcance y profundidad que aquellas establecidas en el liberalismo contemporáneo, su modelo normativo del reconocimiento tiene una seria limitación, que consiste en circunscribir el alcance de su concepción de la libertad a las sociedades más desarrolladas de Occidente. Honneth considera que se produciría un cuadro equivocado en la reconstrucción de las condiciones sociales de la libertad si se abandona el núcleo de Occidente y con estos conceptos se dirige a otros países en los que no se puede afirmar que las condiciones de vida tengan la propiedad buscada con su teoría del reconocimiento.

Die Burgen des Kantons Aargau
Authors: Frey Peter ,   Kantonsarchäologie Aargau
Published: April 2023

Der Aargau ist ein Burgenkanton. Neben der bekannten Habsburg – Stammburg eines Adelsgeschlechts, das zu einer der mächtigsten Dynastien Europas aufstieg – sind rund hundert weitere Burgstellen bekannt. Burgen prägen die Landschaft: Ihre Ruinen, oft weithin zu sehen, sind beliebte Ausflugsziele. Vor Jahrhunderten zu Schlössern umgebaut, sind Burgen heute Sitz von Museen oder werden immer noch bewohnt. Viele von ihnen sind aber nur unscheinbar im Boden erhalten. Das Werk fasst den aktuellen Kenntnisstand zu den Burgen im Aargau zusammen. Vorgestellt werden die Resultate aus archäologischen Untersuchungen von 34 Burgen und der Wissensstand zu allen anderen dem Autor bekannten Burgen. Im einleitenden Teil finden sich eine kurze Geschichte des Adels im Aargau und ein Abriss zur Entwicklung der Burgen. Ihre Ursprünge liegen in den bisher kaum erforschten Herrenhöfen des Frühmittelalters. Nach einer Blütezeit im Hochmittelalter setzte ein allmählicher Niedergang der Burgen ein oder sie wurden zu Schlössern und Festungen um- und ausgebaut. Das Buch zeigt die Burgenlandschaft des Kantons Aargau in ihrer ganzen Vielfalt und zeitlichen Tiefe. Damit ist die Publikation ein Standard- und Nachschlagewerk für alle Interessierten.
The Influence of VR Tourism’s Perceived Benefits on Value Experience and Intention to Visit: The Moderation Effect of Involvement
Authors:   IAGBT, Cui Zhe , Zhou Yan , Kim Yeong-Gug
Published: April 2023

Purpose - The current study focuses on the effects of different degrees of attention to information provided by VR tourism. The purpose of this study was to explore the impact of VR tourism on potential tourists’ intention to visit, and provided an analysis of how information about a tourist destination moderates VR users’ perceived value and intention to visit.
Design/Methodology/Approach - The study uses the SPSS 26.0 and AMOS 26.0 statistical packages to analyze a sample of 328 respondents are analyzed using structural equation modeling.
Findings - The results suggest that usefulness, ease of use, enjoyment, interactions among the perceived benefits of VR tourism has a positive effect on perceived value except for Presence. Perceived value is positively correlated with intention to visit intention. Perception of value experience has a significant positive impact on the intention to visit a tourist destination. However, while the overall intention to visit is higher with high involvement, increasing experience with tourism has little influence on the intention to visit.
Research Implications - The study found that the perceived value of the VR experience has a direct and significant positive impact on the intention to visit, such that a good perception of value in the experience is a driving factor in users’ visit a tourism destination. The implications of this study for future research are discussed.
The concept of “real property” in the 21st century: possible options for changing the content
Authors: Rodionov Andrey B.
Published: April 2023

Devoted to the analysis of the “real property” concept evolution. The digitalization of economics and law requires a new awareness of the content of basic concepts of property law and, above all, a deeper understanding of what an immovable thing is. The direction of property law evolution largely depends on what this understanding will be. The purpose of the presented work is to determine the possible directions of the “real property” concept evolution. The work used such methods as the method of historical dialectical analysis, interdisciplinary research, comparative legal analysis. It is determined that the content and fundamental changes in the content of the concept “real property” were associated with the content and changes in the main economic settings of the ancient Roman period of history, the Middle Ages and the New Age. It is established that the origin of the concept of “real property” was associated with the introduction of the fiction of a single real estate object into the ancient Roman legal order, which, in turn, was associated with economic practices focused on class control over the land plots of cities. It is concluded that in the period of the New Age, a fundamental overcoming of the dominance of the fiction of a single real estate object in the conceptual space began, which was associated with new economic needs born of the industrial revolution. It is noted that in the course of economic evolution the very concept of “real property” can be overcome. This is due to the fact that as the law develops and the digital economy emerges, the number of fictions of immovable things increases. This state of affairs objectively leads to a radical change in the legal discourse in terms of understanding what an immovable thing is.
