Be stars are B-type main-sequence stars that display broad Balmer emission lines in their spectra. Identification of the Be population is essential to further examine the formation and evolutionary models. We report the detection of classical Be (CBe) stars from observations with the Large sky Area Multi-Object fiber Spectroscopic Telescope Medium Resolution Survey Data Release 7 (LAMOST MRS DR7). We used a deep convolutional neural network, ResNet, with an 18 layer module to examine the morphology of the Hα profile. We identified 1162 candidate Be stars from the collection of 2,260,387 spectra for 789,918 stars in the database. The ResNet network achieves a Be-star classification accuracy of 99.5%. Among the detections, 151 of these are prior known Be stars crossmatched from the literature. By applying a three-step test, we identified 183 new CBe stars. We find that 41 CBe stars are members of known open clusters. Based on an investigation of the kinematics of the identified CBe stars from the Gaia EDR3 astrometric solutions, we identified 16 new runaways. These new identifications will provide a reference for future follow-ups to further investigate their physical properties.

Published: June 2022

A spectroscopic study of atomic oxygen (O i) is performed using the Fourier-transform vacuum ultraviolet (VUV) spectrometer at the Dichroïsme Et Spectroscopie par Interaction avec le Rayonnement Synchrotron beamline of the SOLEIL synchrotron. Transition frequencies of O i lines in the range between 76,000 and 151,000 cm−1, corresponding to wavelengths between 665 and 1306 Å, are presented. In the wavelength window a data set of 208 lines is obtained for which line centers were determined at an accuracy of ≤0.035 cm−1, verified through a comparison with previous VUV-laser spectroscopy at an accuracy of 0.008 cm−1. Transitions to upper states belonging to several ns and nd Rydberg series that converge to the 4S3/2, 2D, and 2P ionization limits are presented. Besides studies on the main 16O isotope, measurements of the 18O isotope are also performed, for which an enriched sample of 18O2 gas is used. A least-squares optimization analysis is performed after merging the present new data set with some relevant accurate literature data to extract a list of level energies at high accuracy. When comparing with the database of the National Institute of Standards and Technology, good agreement is found for levels with low principal quantum numbers n ≤ 7 or below excitation energies of 108,000 cm−1; however, significant deviations were found for levels with n > 7. The main result of the present study is the realization of an improved data set of transition frequencies and level energies for O i, with its usefulness demonstrated in a comparison with high-resolution astronomical spectra showing absorption in the line of sight to distant quasars.

Authors: Wenang Supriyatiningsih , Kurniawan Muhammad , Lelle Ralph J. , Inayati Inayati , Rismawati Ima
Published: June 2022

BACKGROUND: Gonorrhoeae is a type of sexually transmitted disease (STD) caused by the Neisseria gonorrhoeae (NG) bacteria. It is a commonly reported bacterial STD with rising cases in men and women in Indonesia. Gonorrhoeae is commonly asymptomatic. Therefore, the disease is often left undiagnosed, untreated, and causes further complications.

AIM: This study aims to describe the incidence and distribution of gonorrhoeae in AMC Muhammadiyah Hospital, Yogyakarta, Indonesia. The importance of screening and health service improvement toward preventing transmission and complications are also discussed.

METHODS: It is a descriptive observational study and aims to identify the percentage of NG in patients with clinical symptoms of STDs. The non-randomized sampling technique was used with 710 respondents. The inclusion criteria were women aged 15-44 years with STD symptoms who underwent vaginal smear examinations for NG, Bacterial Vaginosis (BV), yeast cells-pseudohyphae Candida sp, and were willing to be respondents. The exclusion criteria were women with STDs and HIV. Microscopic characteristics of NG were examined by Gram staining the vaginal swab samples from the respondents.

RESULTS: It was found that 623 (87.7%) out of 710 respondents had NG with clinical symptoms of leukorrhea and itchiness. The vaginal smear results also found bacterial vaginosis and candidiasis.

CONCLUSIONS: Screening and health facilities providing STI-related services are essential to prevent the transmission of gonorrhoeae and reduce the high incidence and severity of gonorrhoeae in reproductive health.

Published: June 2022

DNA metabarcoding is particularly helpful for monitoring taxonomically complex communities and hard to identify morphologically, such as several zoo and ichthyoplankton, which contain eggs and larval stages of unknown species. However, the efficiency of metabarcoding in diversity recovery is dependent on the targeted genetic markers and primers employed. In this work, we compared the performance of three different primer pairs from cytochrome oxidase subunit I (COI) genetic marker in species detection from marine mesozooplankton samples and its potential to be implemented in biomonitoring programs. We employed the mlCOIintF/LoboR1 primer combination targeting marine metazoans, and two newly designed fish-specific primer cocktails for targeting the ichthyoplankton. Mesozooplankton samples were collected at 4 locations on the Portuguese coast – 1 in the northwest (Viana do Castelo) and 3 in the south (coastal lagoons of Ria de Alvor and Ria Formosa, and in the river Guadiana estuary). Bulk community DNA was extracted using a non-destructive protocol and amplicon libraries produced for the 3 primers combinations. After quality-filtering bioinformatic steps, we obtained 3.04 x 105 usable sequences, of which 76.26% were clustered into OTUs (operational taxonomic units) and 46.30% were identified at species level - corresponding to 103 taxa from 8 different metazoan Phyla. The most diverse classes were Malacostraca, Actinopterygii, and Copepoda. As expected, the generic primer pair for marine metazoa (mlCOIintF/LoboR1) retrieved a higher number of species (94) compared with the fish-specific primer cocktails (30). Nevertheless, 9 % of the total species were identified exclusively by the cocktails, of which 42% were fish. These results confirmed the potential of metabarcoding as a tool for profiling zooplankton communities and to assess ichthyoplankton diversity. Multiple primers pairs increased species detection from different taxonomic groups, being the protocol optimization for fish-specific primer cocktails, the next step for its implementation in fish stock assessments.
Detection and monitoring of invertebrate non-indigenous species through DNA metabarcoding in a recreational marina of the Northwest of Portugal
Authors: Amaral Fábio , Lavrador Ana Sofia , Duarte Sofia , Costa Filipe , Vieira Pedro
Published: June 2022

In marine and coastal ecosystems, the proliferation of non-indigenous species (NIS) is among the top causes of biodiversity loss. Thus, it is essential to prevent the entrance and proliferation of NIS by detecting their presence as early as possible at the most susceptible locations, such as ports and marinas. Molecular techniques, like DNA metabarcoding, may be faster and more effective in the early detection of NIS. Its high sensitivity allows the detection of species at any stage of their life cycle and when present at very low densities. However, the detection power can be affected by the methodologies employed through the DNA metabarcoding analytical chain. This study aimed to assess the seasonal effects, sampling method (hard and artificial substrates, zooplankton and eDNA) and genetic marker (COI and 18S) in the recovery of NIS through DNA metabarcoding. Sampling was conducted in 3 seasons (spring, autumn, and winter of 2020/2021) in the “Porto Atlântico” marina, which is located near a major commercial port of the North of Portugal (Leixões). Overall, 626 species were identified through DNA metabarcoding, with the dominance of Crustacea, Ascidiacea and Mollusca. The sampling method and season significantly affected the marine invertebrate species recorded, for both molecular markers, with a high proportion of species detected exclusively using one method (7 to 20%). Overall, 31 NIS were detected, 7 of which are considered invasive and 6 are presumed new records in mainland Portugal. Zooplankton sampling and winter were, respectively, the method and the season where the highest number of NIS was detected, but the maximum number was only attained when pooling the results from all sampling methods and seasons. Our study highlights that different sampling methods and genetic markers, over different seasons, are needed to detect NIS in marine habitats, since the number of species shared by these factors is low.

Published: June 2022

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is a syndrome of diverse etiology and unclear pathogenesis, with an incidence of 5-15% and varying prognosis. Cardiac magnetic resonance imaging (MRI) is playing an increasing role in the diagnosis of MINOCA and in distinguishing the causes that led to it, while being at the same time an important predictor of prognosis in these patients. We present a 40-year-old man with clinical, laboratory and instrumental data for acute coronary syndrome complicated by acute heart failure. The invasive assessment ruled out obstructive coronary heart disease as well as Takotsubo cardiomyopathy. MINOCA and myocarditis were discussed in the differential diagnostic plan. To differentiate them, cardiac MRI was performed, which confi rmed the diagnosis of „myocardial infarction with non-obstructive coronary arteries“.

Authors: Petrov I. , Cherneva A. , Vasilev S. , Gecov Y. , Stankov Z.
Published: June 2022

Mitral regurgitation or mitral insuffi ciency is the second most common valve pathology requiring a surgical treatment worldwide. It is characterized by an abnormal return of blood from the left ventricle to the left atrium during the systole. The incidence of mitral regurgitation increases in line with the rise in the life expectancy and the overall aging of the world population. According to the pathoanatomy and the mechanism of development, there are two main types of mitral regurgitation: a primary (degenerative) regurgitation and secondary (functional) regurgitation. In the fi rst type, there is organic damage to the valve and/or the valve apparatus, and in the second type, there is a secondary dysfunction of the mitral valve due to damage to the structure and/or the function of the left ventricle. The treatment of choice for the management of the mitral regurgitation is a surgical intervention. In recent years new high-tech transcatheter methods of treatment have been introduced in clinical practice. The most popular and proven method of treatment in patients who could not undergo classic cardiac surgery is the MitraClip edge-to-edge transcatheter approximation system. Other endovascular methods of treatment are percutaneous plasty device Pascal (Edwards Lifesciences) and Cardioband using transseptal approach, and also NeoChord and Harpoon using transapical approach.

Published: June 2022

This study presents data from the national electronic registry BG-EPHY on electrophysiologic (EP) cardiac ablations in 2021. Material and methods: This is a retrospective study of a full one-year sample of the BG-EPHY registry. Sex and age distribution of the patients, number of ablations, electroanatomic mapping (EAM), irrigated and cryoablations, distribution of different types of arrhythmias, acute procedural success and complications are presented. Results: In 2021 fi ve EP centers performed 872 ablations in 546 men (62.6%) and 326 women (4.4% increase compared to previous year), incl. 6 ablations in pediatric patients (0.7%). EAM was used in 60.9% of the procedures, irrigation catheter was used in 55.2%, cryoballoon catheter – in 6%, and intracardiac echocardiography – in 4.2%. The most common ablation was pulmonary vein isolation, followed by ablation for AV nodal reentrant tachycardia and typical atrial fl utter. The acute success was over 98%, while intraprocedural complications were less than 2%. Conclusion: The national registry of electrophysiology collects systematically and continuously basic data on all ablations of cardiac arrhythmias performed in the country. In 2021, during a continuing COVID-19 pandemic the number of ablations increased slightly compared to the previous year. Distribution of EP procedure types was similar to previous years. Acute success was very high, while intraprocedural complications were rare.
A price tag on species
Authors: Kõljalg Urmas , Nilsson R. Henrik , Jansson Arnold Tobias , Zirk Allan , Abarenkov Kessy
Published: June 2022

Species have intrinsic value but also partake in a long range of ecosystem services of major economic value to humans. These values have proved hard to quantify precisely, making it all too easy to dismiss them altogether. We outline the concept of the species stock market (SSM), a system to provide a unified basis for valuation of all living species. The SSM amalgamates digitized information from natural history collections, occurrence data, and molecular sequence databases to quantify our knowledge of each species from scientific, societal, and economic points of view. The conceptual trading system will necessarily be very unlike that of the regular stock market, but the looming biodiversity crisis implores us to finally put an open and transparent price tag on symbiosis, deforestation, and pollution

Published: June 2022

Energy audits are an essential tool for improving energy efficiency and saving energy in various sectors, especially in the building sector. It is a vital tool for supporting the renovation of buildings and attaining carbon neutrality in this sector. In this article, we report an energy audit of a university campus based in Fez, Morocco. A detailed diagnosis combined with an accurate analysis of the electrical consumption of each system on campus has enabled us to identify the energy consuming systems and to propose a suitable energy saving strategy. A photovoltaic plant has been implemented at the campus to reduce its dependence to the electrical grid. The proposed actions resulting from this energy audit revealed that the campus can save 161 MWh of electrical energy and avoid 120 tons of CO2 emissions per year. This corresponds to a 33% reduction compared to the initial situation. The total investment has been estimated at 55 800 ＄ and the overall payback period does not exceed 2.8 years.
Multiobjective particle swarm optimization with direction search and differential evolution for distributed flow-shop scheduling problem
Authors: Zhang Wenqiang , Li Chen , Gen Mitsuo , Yang Weidong , Zhang Zhongwei , Zhang Guohui
Published: June 2022

As a classic problem of distributed scheduling, the distributed flow-shop scheduling problem (DFSP) involves both the job allocation and the operation sequence inside the factory, and it has been proved to be an NP-hard problem. Many intelligent algorithms have been proposed to solve the DFSP. However, the efficiency and quality of the solution cannot meet the production requirements. Therefore, this paper proposes a bi-objective particle swarm optimization with direction search and differential evolution to solve DFSP with the criteria of minimizing makespan and total processing time. The direction search strategy explores the particle swarm in multiple directions of the Pareto front, which enhances the strong convergence ability of the algorithm in different areas of Pareto front and improves the solution speed of the algorithm. The search strategy based on differential evolution is the local search strategy of the algorithm, which can prevent the multiobjective particle swarm optimization from converging prematurely and avoid falling into local optimum, so that a better solution can be found. The combination of these two strategies not only increases the probability of particles moving in a good direction, but also increases the diversity of the particle swarm. Finally, experimental results on benchmark problems show that, compared with traditional multiobjective evolutionary algorithms, the proposed algorithm can accelerate the convergence speed of the algorithm while guaranteeing that the obtained solutions have good distribution performance and diversity.

We establish the existence of solutions for a class of stochastic reaction-diffusion systems with cross-diffusion terms modeling interspecific competition between two populations. More precisely, we prove the existence of weak martingale solutions employing appropriate Faedo-Galerkin approximations and the stochastic compactness method. The nonnegativity of solutions is proved by a stochastic adaptation of the well-known Stampacchia approach.

This study investigates the relationships among social appearance anxiety, the fear of missing out (FOMO), and cyberloafing. The study further investigates the impact of social appearance anxiety and FOMO on cyberloafing. The research model is tested by employing a structural equation modeling (SEM) approach based on data collected from 396 higher education students. The results suggest that social appearance anxiety has a significant impact on FOMO and that FOMO has a significant impact on cyberloafing. However, the mediation analysis results suggest that FOMO full mediates the relationship between social appearance anxiety and cyberloafing.

Published: June 2022

Crew resource management (CRM) is the product of a paradigm shift in safety thinking from ‘finding the problem' to ‘finding the solution'. Until the ‘crash of the century' took place in Tenerife in 1977, the first officer was only to be seen and not heard. He was ‘a good for nothing' sandbag sitting in the right seat. But all changed in 1977-1978 with the introduction of CRM, initially cockpit resource management and now crew resource management. It was so elaborate a system created out of necessity by aviation that no matter which high-reliability organization (HRO) was and is present, they took it up as the most efficient and effective method to reduce human fallibility. Starting from the civil nuclear technology sector to medical science to firefighting, all have adhered to CRM principles. The latest innovation which comes across from the experts is threat and error management (TEM), which is coincidentally the revision or version six of CRM. The aim of the present effort is to relate how CRM has come of age, the purpose behind it, and a deeper view of its successful cross-functioning into various vocations and industries.
Model of Air Cargo Supply Chain Resilience
Authors: Luangpituksa Chonnikarn
Published: June 2022

The air transport sector provides global connectivity via trade flows and tourism. The outbreak of the COVID-19 pandemic caused this sector to alternate between long periods of continued growth and long periods of negative growth. The air cargo airlines have permanently endeavored to maintain operations sufficiently robust to be resilient to the impacts of different internal and external disruptive events to maintain the guaranteed quality of services to their users and consignees. One approach to deal with disruptions in the development of air cargo supply chain systems is resilience. The resilient air cargo supply chain requires two critical capacities: the capacity for reliability and the capacity for restoration under disruptive condition.

Investigation of Terahertz Wave Propagation along Symmetric Coplanar Strpline on Multilayer Dielctric Substrates
Authors: Wang Zhi Hui
Published: June 2022

Characteristics of the symmetric coplanar strip line on multi-layer dielectric substrates expressed in analytic formulas have been obtained using conformal mapping. But in most previous presented papers, the metal strip is considered as infinitely thin or PEC while the influence of dielectric substrates are not considered. In this paper, the propagation characteristics of symmetric coplanar strip line with finite conductivity and finite metal strip thickness on multilayer substrates are analyzed by conformal mapping at THz regions. The influences of metal strips and dielectric substrates on the propagation characteristics of CPS are also given. The numerical results are very useful for the development of terahertz devices and terahertz material.

Published: June 2022

The formation of LiFeO2 lithium ferrite from unmilled and milled Fe2O3-Li2CO3 mixture was studied by X-ray powder diffraction (XRD). The ball milling was perform via AGO-2S high-energy planetary ball mill at a rotational speed of 2220 rpm for 60 min. Solid-phase synthesis was carried out by conventional laboratory furnace at 600 °C. Using PowderCell 2.4 software, the structural parameters of the reagents and ferrite obtained from these were determined. According to the XRD data, the crystallite sizes of the milled reagents decreased, while the strains increased. It was found that the synthesized ferrite is characterized by multiphase composition consisting of unreacted initial reagents, α-LiFeO2, γ-LiFeO2 and α-Li0.5Fe2.5O4 phases, the concentration of which depends on the prehistory of the mixture.
Research of Drop Formation during Electric Arc Surfacing with the Use of Mechanical Control Impacts on the Electrode
Authors: Lavrova Elena , Ivanov Vitaliy , Il'yashchenko Dmitry
Published: June 2022

Investigations of the influence of the parameters of mechanical effects on the temperature and mass of electrode metal droplets during electric arc surfacing with electrode materials of various chemical composition and type have been carried out. The main regularities of the process of droplet transfer during melting of a strip electrode with the introduction of control mechanical impacts have been established. The optimal range of the oscillation frequency of the strip electrode end is 40 ÷ 80 Hz, in which the average droplet diameter decreases to 1.3 ÷ 1.5 mm, and the mass to 0.08 ÷ 0.1 g. As a result of the research, it was found that, during electric arc surfacing with a strip electrode, changing the parameters of mechanical control impacts on the strip end allows not only to control the drop transfer frequency, but also to reduce the size and temperature of the electrode metal droplets, ensuring a decrease in heat input into the base metal and the formation of a favorable structure of the deposited weld metal.

Published: June 2022

This study assessed the Effects of methanolic leaf extracts of Jatropha curcas, Alchonnea cordifolia, Secamone afzelii in Doxorubicin-induced hypertensive nephropathy in pregnant Wistar rats. Plant samples (leaves) were washed severally with distilled water, air-dried, and crushed to powder and were filtered, then soaked in 200mL of methanol for 12 hours. The LD50 was determined to ascertain the safety of the plant extracts for use. Female Wistar rats, aged 3 days apart, used in the study, were acclimatized for one week. Doxorubicin nephropathy was induced with 3.5mg dose intravenously through the caudal vein. Urea levels were found to have increased significantly in the third trimester (9.3 mmol/L) in the hypertensive nephropathic group. Hypertensive nephropathy also caused an increase in plasma Creatinine levels (333.64 μmol/L) and (172.73 μmol/L) in the third trimester and postpartum, respectively. The administration of plant extracts resulted in a significant decrease in urine creatinine (845.45–481.82 μmol/L) and a significant increase in Protein- Creatinine Ratio (PCR, 3.0–7.3 mg/dL) in the nephropathic group, but a contrary report in the post-partum group, with significant increases in micro-protein (17.1–21.9 mg/dL). Plasma urea and plasma creatinine had a significant relationship in the third trimester (r=0.853 and 0.810, p=0.01). Plasma urea, on the other hand, had no significant association with plasma creatinine throughout the postpartum period. This study’s findings suggested that Jatropha curcas, Alchonnea cordifolia, and Secamone afzelii extracts could be useful in the treatment of chronic renal disease.

OBJECTIVES

Comparative analysis of the aspects of interconnection and differentiation/protocol integration with narrative medicine.

Empirical evaluation of the effectiveness and efficiency of strategic narrative techniques on individual cases in terms of the development of corrective emotional experiences aimed at reducing/remitting the symptomatic picture and raising the level of psychophysical and socio-relational well-being of the patients treated.

METHODOLOGY

Action research, operational diagnosis, narrative techniques of the reference strategic intervention protocols.

RESULTS

On the basis of the applied protocols, a complete remission of symptoms was observed in the psychopathological areas treated, with an increase in coping functions and adaptive modalities in the treated cases of hypochondriacal disorder and post-traumatic stress disorder, attested from follow-up to 6, 12 and 24 months after the end of the treatment.

CONCLUSIONS

In the two cases studied, the use of strategic narrative techniques, with their peculiar characterizations, appears to be effective as a tool for inducing corrective emotional experiences necessary for change and improvement in the psychopathological structure of patients and their possible application, in the context of principals of health psychology, in integration-continuity with narrative medicine.

There is high prevalence of psychological distress in patients diagnosed with neurological disorders. A cross-sectional study was done among inpatients from the department of neurology in a tertiary care centre in South India to assess prevalence of anxiety, depression, and barriers to mental health-care utilization. Anxiety and depression were estimated using the Hospital Anxiety and Depression Scale (HADS). There is a high prevalence of psychological distress among the study participants. Proactive inquiry and screening of distress by the treating team may help identify psychological distress. Patients are more conforming and open to treating doctor. Barriers to mental health-care utilization included stigma, patient perception regarding treating doctor's attitude, patients' perception regarding distress, and doctor's perception regarding patient distress. There is a need for measures to alleviate stigma.

The difference addressed earlier may not be a very hype intervention, unlike what science has been giving us, but this can do a lot in setting us free from this very pandemic, COVID-19. The fight against COVID-19 is a biological warfare that cannot be won at the cost of ammunitions but with proper knowledge, information, and communication, through various advertisements, banners, and posters. This is an hour-saving time where COVID-19 is rapidly evolving. The entire focus is placed on caring for the patient and on abandoning community spread of the disease in order to decrease disease burden; nevertheless, the rapidity of COVID-19 has proven to be grave for medical education and severely disrupted the medical curriculum.

Text messaging health service is used to improve quality of life of people living with diabetes in Eastern Nepal. It has been projected that the number of diabetic patients has increased to 170% from 1995 to 2025 in developing countries and to 41% in developed world. The objectives of the study were to assess the quality of life of people living with diabetes, to prepare and provide health education, and to evaluate the effectiveness of health education program and mobile/telephone health services provided to the diabetes patients.

Materials and Methods:

The study was conducted among consecutive stable ambulatory patients, >18 years old, and 396 patients diagnosed with diabetes for at least 3 months were included in the study. The education intervention was continued for 6 months by the principal investigator and a trained nurse.

Results:

Most of the respondents (53.3%) were of the age group 40–60 years; female (59.34%); Hindus (97%); and of the Janjati ethnic group (52.5%). The majority (96.5%) were married and self-employed (70.7%). About 30% of the respondents belonged to the poor economic status group. Most of the respondents had type II diabetes mellitus; about 34% of the respondents had a family history of (sibling) diabetes. Most of them were non-vegetarians (88.9%). About 16% of the respondents were obese. Regarding habits, 14% had tobacco chewing, 5% had gutka chewing, 8% had smoking, and around 8% had alcohol consumption habits. Regarding treatment, about 84% were on oral hypoglycemic agent, 22% on insulin therapy, 68% on diet control therapy, 58% on weight control, and 4.5% on herbal therapy. It was found that the mean knowledge score before education intervention was 22.53 and after education intervention was 35.32. It was found that the difference in the mean score calculated using t-test between knowledge before and after education intervention program was significant (P < 0.01).

Conclusion:

It can be concluded that the education intervention program and SMS mobile service provided to diabetes patients were found to be very effective.

L’intensification de la production du maïs au Burkina Faso passe par une fertilisation adéquate sur des sols propices. L’objectif de cette étude était de développer à l’aide du modèle Information and Decision Support System (IDSS), un outil d’aide à la décision en matière de recommandation d’engrais pour la production du maïs dans la zone sud soudanienne du Burkina Faso. Les données sur les coûts de l’unité de fertilisant ont été calculés suivant les prix du marché. Le prix de vente du maïs grain a été estimé pour une période allant de la récolte au mois de juin à 0,263 dollars US. Dix options de fertilisation incluant un témoin et la recommandation vulgarisée ont été testées sur la variété Massongo de maïs. Les résultats ont montré que les doses 80N-30P-40K, 120N-30P-40K, 60N-10P-12K (dose vulgarisée) et témoin sans engrais ont été efficientes selon les caractéristiques des sols. L’application des doses efficientes d’engrais a permis de faire passer la superficie couverte par des rendements grains supérieurs à 3 000 kg ha-1 de 39,23% des unités de sols avec la dose vulgarisée à 62,33%. Aussi, des rendements compris entre 3 144 et 4 630 kg ha-1 avec des marges brutes comprises entre 557,322 dollars US par ha-1 et 898,098 dollars US par ha-1 ont-ils été obtenu. Ces cartes constituent des outils d’aide à la décision pour la production du maïs. Elles peuvent servir de référence pour l’élaboration et/ou la mise à jour d’autres cartes de recommandation d’engrais.

This study examines the influences of Online Interaction Propensity in university confessions pages, Attitude toward participating in university confessions pages, and Higher Education involvement on the engagement of students with their university. The relational outcomes comprising student’s word-of-mouth activity and praise are also investigated. The quantitative online and offline surveys was conducted on 509 participants targeting university students and graduates who follow or interact with posts on universities’ confession pages. The collected data was then processed and employed SEM path analysis to empirically examine the proposed conceptual model. The results determine that both online interaction propensity and higher education involvement have significant impacts to the engagement of student to their university while the attitude of student toward participating in university confessions pages has no impact to this engagement. In addition, the influence of students’ engagement on their word-of-mouth is proved. The study shows a deep understanding on the drivers relating to the confession pages’ participation of students’ engagement with their university, and other way to generate positive student - university relationship outcomes. The results suggest universities should not overlook the impact of student's participation in university confession pages, then adopt feasible and practical approaches in managing their relationship with students to stimulate their word-of-mouth. The research provides the insights that have not been studied previously in the Vietnam higher education context. Although it is practically observed that student’s engagement is impacted by their participation in university confession pages, there is lack of intensive work on this issue.
Свето Миро: литургичко–канонско разматрање
Authors: Милошевић Ненад
Published: June 2022

У раду је изложен богословско-историјски преглед припреме и освећења светога Мира. У оквиру овог истраживања издвојена су три момента у вези са назначеном темом. Први момент се односи на објашњење светотајинског и богословског смисла и значаја светога Мира. Тим поводом су консултовани релевантни литургијски извори и сведочанства светих отаца литургичара који су посвећени улози светога Мира у освећењу човека, пре свега у тајни миропомазања. Други момент тиче се целокупног историјског развоја чина припреме и освећења Мира. Еклисиолошки аспект светога Мира је коначно трећи момент на који рад указује. Следствено, изложена је проблематика савршитеља освећења Мира у Православној Цркви још од најранијег времена, па све до савремених сложених међуправославних односа. Рад доноси један еклисиолошки аспект припреме, освећења и улоге светога Мира у светотајинском животу хришћана, који се креће средњим путем између два опречна става, изложених у питању: да ли Миро треба да освећује Константинопољски патријарх или сваки предстојатељ помесне Цркве?
