Authors: ATİOĞLU Eyup , ŞAHİN Osman Nuri
Published: June 2022

Many factors play a role in determining the level of development in countries, and one of the main factors is FDI. To attract foreign capital to the country, it is necessary to realize the developments desired by the foreign capital and to pave the way for investments. The strong transportation infrastructure contributes to the development of the country not only in economic terms but also in many social and cultural aspects. With all these contributions, the benefits of transportation infrastructure investments make countries attractive for foreign capital. In this study, the relationship between investments in transportation infrastructure and foreign direct investments (FDI) was examined using the Arellano-Bond difference Generalized Method of Moments (GMM). The data set of the study covers the period between 2010 and 2017, and the analysis was carried out using data from 30 OECD countries. According to the findings, it has been determined that total transportation infrastructure investment expenditures positively affect foreign direct investments.

Yüksek frekanslı işlemlerin sermaye piyasalarında kullanımıyla birlikte yatırım ortamı değişmiş, yüksek frekanslı işlemlerin piyasa etkinliğinin tespitine ilişkin çalışmalarda araştırılması önem kazanmıştır. Yüksek frekanslı işlemlerin, kullanıldıkları piyasalarda hız ve teknoloji avantajları nedeniyle piyasa etkinliğini etkiledikleri ve kısa zaman aralıklarında zayıf formda piyasa etkinliğinin reddedilmesine yol açtıkları gözlemlenmiştir. Borsa İstanbul’un BISTECH sistemine geçmesiyle 2016 yılından itibaren yüksek frekanslı işlemler Türkiye piyasalarında kullanılmaya başlanmıştır. Bu çalışmada yüksek frekanslı işlemler dikkate alınarak, etkin piyasa hipotezinin Borsa İstanbul’daki geçerliliği sınanmıştır. Zayıf formda piyasa etkinliğinin tespiti için literatüre benzer bir şekilde varyans oranı testi kullanılarak rassal yürüyüş hipotezi test edilmiştir. Veri seti olarak Borsa İstanbul’un temel göstergesi olan BIST100 endeksinin 05/02/2019 ve 05/02/2020 dönemleri arasındaki dakikalık getirileri kullanılmıştır. Borsa İstanbul’un dakikalık zaman dilimlerinde zayıf formda etkin olmadığı gözlemlenmiştir. Yüksek frekanslı işlemlerin kullanıldığı Borsa İstanbul’da rassal yürüyüşün olmadığı, durağanlığın mevcut olduğu tespit edilmiştir. Bu sonuç Borsa İstanbul’da yüksek frekanslı işlemler kullanılarak piyasanın üzerinde getiri elde etmenin mümkün olduğunu ifade etmektedir.

Hepatitis C Disease Detection Based on PCA–SVM Model
Authors: GÜNDOĞDU Serdar
Published: June 2022

Hepatitis C is a liver disease caused by infection with the hepatitis C virus (HCV), which is transmitted through the blood. The disease can lead to diseases ranging from a mild form to serious lifelong illness. Studies to detect the disease early and reduce its effect are continuing. This study proposes an effective support vector machine model supported by principal component analysis for detecting hepatitis c disease. The dataset consisted of twelve independent variables, each containing 582 samples, and these variables were used as inputs to the two classifiers, support vector machine (SVM) and artificial neural network (ANN). The accuracy, sensitivity, specificity, MCC and KAPPA were calculated using two classification models. In addition, performance comparisons of classifiers were made for the two cases with and without PCA (principal component analysis) applied to the inputs. The highest accuracy (98.7%), sensitivity (99.1%), specificity (95.2%), MCC (92.3%) and Kappa (92.3%) in the binary class label were obtained with the SVM with PCA. In the four-class label, the highest accuracy was achieved with the same model with 95.7%. The results show that an SVM classifier model, in which PCA-reduced independent variables are applied to its inputs, may be a candidate for an accurate prediction model to predict hepatitis C disease.

Published: June 2022

There has been an increase in the general spending and consumption habit of people, the consequence of which is an increase in the quantity of municipal solid wastes (MSW) being generated particularly in urban areas. Yola, the capital of Adamawa State in the northeast region of Nigeria an urban area also has its share of problems associated with solid wastes management. In addition, the city like most other cities in Nigeria experiences inadequate electricity supply. Hence the need for this research - to assess the technical and economic potentials of recovering energy from the MSW generated in Yola using incineration as the technology of choice. The American Society for Testing and Materials (ASTM) method (ASTM D5231) was used to sample and characterise the waste disposed of in the city’s dumpsites. It was found that the average calorific value of the MSW disposed of in the city’s dumpsite is 1,515.67 kcal/kg. It was also found that if incineration is used as the preferred waste-to-energy technology, a total of 3,748.60 kW of electrical energy could be recovered from the three dumpsites studied. The economic analysis conducted showed that energy recovery via incineration has an average internal rate of return (IRR) of 252%. The following conclusions were drawn from the results obtained: The quantity and composition of MSW disposed of at dumpsites in Yola is suitable for energy generation via incineration; from an economic perspective, incineration of MSW is a viable waste-to-energy technology for Yola.
The Effect of Storage Temperature on Threat Zone Caused by an Ammonia Release from a Storage Tank
Authors: EKİNCİ Mustafa Serhat , AKMAN Abdurrahman
Published: June 2022

In this study, the threat zone that may occur as a result of an accidental release of an-hydrous ammonia, a flammable and highly toxic substance (Flammability:1, Health:3, NFPA 704), which has many uses, was investigated. A fire can be prevented by taking precautions such as not keeping ignition sources in the environment as a result of the ac-cidental release of ammonia gas. However, although its ignition is prevented, it can cause harm to humans and the environment due to its highly toxic nature. Therefore, the toxicity of ammonia was taken into account in this study. A common type of storage of anhydrous ammonia is in a horizontal cylindrical tank at ambient temperature and its vapor pres-sure. Therefore, in this type of storage, storage is carried out at different temperatures in different seasons. This study aims to examine the effect of storage temperature on the size of the threat zone, taking into account the knowledge that the storage temperature will change in seasonal conditions. Areal Locations of Hazardous Atmosphere (ALOHA) and DOW’s Chemical Exposure Index (DOW CEI) methods were used to determine the size of the threat zone, and the results obtained from these two methods were compared. The advantages and disadvantages of the two methods were presented. It is thought that this study will guide the relevant people such as operators who use these methods in calculating the hazard distances in the establishments that store ammonia and will provide awareness that the storage temperature affects the size of the threat zone.

Authors: KARTAL Levent
Published: June 2022

In this study, calciothermic single phase iron boride(Fe2B) production was investigated in a scalable molten salt system, starting from inexpensive, easily accessible oxide materials. First, the formation of Fe2B was examined in detail in the light of thermodynamic data and literature. After, effects of CaO amount (0-10 wt.%) and time (30-60 min) on particle synthesis were investigated under at constant 3.0 V cell voltage and 1273 K temperature. It was determined that the average current increased continuously with the increase in the amount of CaO, and the current efficiency increased up to 7% by weight of CaO. After the CaO ratio was determined, the effect of the electrolysis duration was examined. In durations experiments, it has been observed that, in 30 minutes’ duration, the particles are composed of Fe, Fe2B and FeB, and by increasing the experiment time to 60 min, single-phase Fe2B particles are obtained. The magnetic properties of the single-phase Fe2B particles obtained at the end of the experiment period of 60 minutes were investigated by VSM. The saturation magnetization, permanent magnetization and coercivity values of the Fe2B particles were determined as 90.718 emu/g, 33.311 Oe, 1.684 emu/g, respectively.
Composing Multi-Relations Association Rules From Crowdsourcing Remuneration Data
Authors: Salleh Siti Salwa
Published: June 2022

In crowdsourcing, requesters are companies that require external workers to execute specific tasks, whereas a platform acts as a mediator to match and allocate the tasks to digital workers. To assign it to a worker, the platform must first identify the types of tasks and match them to the appropriate workers based on their level of competency. Each worker has different ICT competencies which affect work quality and remuneration. However, general practise frequently assumes a single level of worker’s capability for all tasks, hence the categorisation of difficulty of tasks is unclear and inconsistent. Apart from causing dissatisfaction among workers, this also implies an absence of incentive standardisation. Therefore, this study explores this matter and which aims to identify and visualise the parameters that affect remuneration determination. To gather the data, focus group discussions and interviews with crowdsourcing players have been conducted. The data comprise a lot of redundancies, therefore an apriori algorithm is used to normalise it by removing redundancies and then extracting significant patterns. Next, an association rule is used to uncover correlations between parameters. To gain a more understandable insight, the data relationship is visualised using an alluvial chart that manages to illustrate the flow. Findings show that task type, outcome variation, and competency requirements demonstrate a degree of interdependence. It is suggested that there is a significant pattern showing that the remuneration scheme is determined by five levels of DW, which are expert, advanced, intermediate, novice, and basic. Advance workers are most likely to participate in the crowdsourcing, and the remuneration scale is suggested to be wider compared to others. The study's findings provide input for remuneration strategy in future work.

With an aging population, prevalence of visual impairment (VI) is expected to increase as well. A retrospective study was conducted involving the files of older adult patients aged 60 years and above from the Primary Eye Care (PEC) Optometry Clinic Universiti Kebangsaan Malaysia (UKM). This study was aimed to determine the prevalence and causes of VI among older adults. This retrospective study was conducted by reviewing files of older adult patients aged 60 years and above who had visited PEC Optometry Clinic UKM from 2009 to 2019. Socio-demographic, health status, status of visual acuity (VA), refractive error, prevalence and causes of VI before and after refractive correction were analysed by using descriptive statistic. Habitual distance VA was measured monocularly using the Snellen chart and recorded in decimal unit. The mean habitual distance VA in the better eye was 0.72+0.31, ranging from 0.41 to 1.03 while the mean VA after subjective refraction in the better eye was 0.88+0.28 which ranging from 0.60 to 1.16. The prevalence of VI based on habitual VA were 16.0%. The main cause of VI based on habitual VA was cataract (53.4%). The refractive status after subjective refraction showed highest percentage of hyperopia (41.9%), followed by emmetropia (32.4%) and myopia (25.7%). The findings of this study emphasise the importance of increased patient education and further expansion of optometric services are required to reduce avoidable blindness.

Gender dysphoria describes the feeling of distress and discomfort experienced when the assigned gender does not match the person’s gender identity. In its severe form, it leads to anxiety, depression and even suicidal ideation or attempts. Unfortunately, this does not end as some transgenders faced significant pressure by cultural, religious, employment, financial and social during the transformation period, hence would de-transition back to their natal gender identity. Gender detransition is a process through which a person discontinues some or all aspects of gender affirmation. During the de-transition, ambivalence, confusion, doubts about their ability to carry out the gender role and responsibilities are common. Gender dysphoria and gender de-transition requires professional help, but the stigma and discrimination hinders them from seeking help from health care providers (HCP). Although these gender-related identity problems are preferentially diagnosed by a specialised psychologist or psychiatrist, primary care physicians often play an important role in this aspect. This case illustrates the health and help-seeking behaviour of a transwoman who had experienced gender dysphoria in the early adolescence year. Long after that, he faced a difficult life, making him de-transition to his original gender. He eventually presented with trivial symptoms in primary care hoping to solve the crisis.

Published: June 2022

Alteplase is a recombinant form of human tissue plasminogen activator (tPA) that converts plasminogen to plasmin essential for fibrinolysis. It is commonly used to treat embolic or thrombotic disorders such as ischemic stroke. Despite its rarity use in ophthalmology, we are reporting the effectiveness of recombinant tissue plasminogen activator (rtPA) in treating an eye with secondary pupillary block as a consequence of severe endophthalmitis. A patient presented with acute endophthalmitis after a complicated cataract extraction. Examination showed severe anterior chamber reaction leading to seclusion pupillae, iris bombe and presence of iridocorneal touch 360-degree. Following intracameral alteplase 2.5 microgram in 0.1 ml given, iris bombe was observed to resolve completely onehour later. Anterior chamber was also significantly deeper and slightly larger pupil compared to before rtPA injection. Due to clearer view of anterior segment, pars planar vitrectomy and extraction of intraocular lens could be performed with significant visual improvement after surgery. Our findings suggest that usage of rtPA, which is alteplase, was effective in treating secondary pupillary block due to intense anterior segment inflammation in endophthalmitis cases. Thus it is useful in replacing the conventional use of laser peripheral iridotomy in treating pupillary block, as the latter potentially aggravates the pre-existing inflammatory condition.

INTRODUCTION: Among the European population of 715 million people, 1.4 million cases of strokes are recorded annually. Of them, approximately 87% are ischemic strokes, and approximately 20% were accounted for by atherosclerosis of the carotid arteries. To prevent an ischemic cerebral event associated with atherosclerosis of brachiocephalic arteries, different surgical techniques have been developed including carotid endarterectomy (CEAE) and carotid artery stenting (CAS). CEAE and CAS reliably reduce the risk of recurrent stroke associated with atherothrombosis, but with this, the level of alterations of cognitive functions and the restoration of cerebral functional deficit have not been widely studied. At present, no randomized studies and meta-analyses have met all the standards of conducting research concerning alterations in cognitive functions in patients with past interventions on carotid arteries. Some medical centers have performed such interventions, but data are not unambiguous: some authors describe the improvement of cognitive functions, whereas others do not note any differences or even see signs of impairment.
CONCLUSION: This literature review highlights an issue concerning the assessment of the alteration of postoperative cognitive deficit in patients with past CEAE or CAS. Comparisons in the context of cognitive cerebral functions in the postoperative period of endarterectomy or stenting and assessment of neurological status in patients with or without a history of acute cerebrovascular accident, different variants of anesthesia, and CEAE techniques are considered.

INTRODUCTION: The severe acute respiratory syndrome coronavirus 2 is associated with the development of arterial thromboses of different locations. This pathology is common in patients with multifocal atherosclerosis. The overwhelming majority of published reports are devoted to the surgical treatment of patients with thrombosis of lower limb arteries. Thus far, no studies of revascularization in the case of extended atherosclerotic lesion and thrombosis of the internal carotid artery (ICA) in patients with COVID-19, have been published.
AIM: To analyze the immediate results of glomus-saving autografting of the ICA with its extended atherosclerotic lesion and thrombosis in the peracute period of ischemic stroke in patients with COVID-19.
MATERIALS AND METHODS: The retrospective study (inclusion period 01.01.201701.03.2020) involved 49 patients with hemodynamically significant extended atherosclerotic lesion of the ICA in the peracute period of acute cerebrovascular accident (ACVA). From April 1, 2020, to May 15, 2021, 26 patients with hemodynamically significant extended atherosclerotic lesion and floating thrombus in the ICA and a positive result of polymerase chain reaction to SARS-CoV-2 were included. In all cases, brain revascularization was performed in the peracute period of ACVA in the volume of glomus-saving autografting of the ICA.
RESULTS: No adverse cardiovascular events were noted throughout the postoperative follow-up period in both groups. In the examination of the reconstruction zone using color duplex ultrasonography, no data for restenosis/thrombosis were recorded. On day 7 after surgery, in both cohorts of patients, significant regression of neurological deficit on the National Institute of Health Stroke Scale was noted: in the first group, the values during admission and day 7 after revascularization were10.5 3.5 and 6.5 1.5, respectively (р = 0.001); in the second group, the values were 12.5 2.5 and 5.5 1.5, respectively (р = 0.001). In both groups, no cases of unstable difficult-to-control arterial hypertension were noted, and no changes were introduced to the antihypertensive therapy.
CONCLUSIONS: Emergency autografting of the ICA with its extended atherosclerotic lesion and thrombosis in the peracute period of ACVA is an effective and safe method of brain revascularization in patients with COVID-19.

INTRODUCTION: Acute decompensation of heart failure (ADHF) is one of the leading diagnoses for hospitalization in therapeutic/cardiologic hospitals worldwide and is associated with a poor prognosis.
AIM: To study the prevalence, clinical diagnosis, approaches to diagnosis, and treatment of patients hospitalized for ADHF.
MATERIALS AND METHODS: A retrospective analysis of 202 medical records of inpatients hospitalized for ADHF in the first cardiology unit of Regional Clinical Cardiologic Dispensary in 2019 was performed. The clinical and instrumental characteristics of the patients, factors that led to hospitalization, and approaches to the diagnosis and treatment were examined.
RESULTS: The prevalence of ADHF was 11.2%, the mean age of the patients was 68.4 10.8 years, and 49.0% were men. The most common causes of ADHF were atrial fibrillation (AF, 31.7%), uncontrolled arterial hypertension (AH, 20.8%), С4С5 stage chronic kidney disease (CKD, 19.4%), and non-adherence of clinical prescriptions (14.4%). Among the most commonly registered etiological factors of chronic heart failure (CHF) were AH (89.6%), AF (67.3%), and coronary heart disease (CHD, 64.9%). The left ventricular ejection fraction (LVEF) was preserved in 48.7% of the patients, intermediate in 21.4%, and reduced in 29.9%. In 2019, in real clinical practice, levels of natriuretic peptides were not determined, and blood electrolytes were not determined often enough (71.8%). The frequency of the administration of angiotensin-converting enzyme (ACE) inhibitor/angiotensin II receptor blockers (ARB-II)/neprilysin receptor antagonists (NRA) and beta-adrenoblockers (BAB) did not depend on the LVEF, which were 84.2% and 76.2%, respectively. Mineralocorticoid receptor antagonists (MCRA) were more commonly used in CHF with low LVEF at 89.2% against 78.7% among all patients (p 0.05). On hospital discharge, ACE inhibitor/ARB-II/NRA therapy was recommended in doses of 21.1%, BAB in 7.6%, and MCRA in 72.0% of target values.
CONCLUSIONS: The prevalence of ADHF in all patients hospitalized in Cardiologic Hospital of Ryazan Regional Vascular Center was 11.2%. The most common causes of ADHF in patients with CHF were LVEF and AH, AF, and CHD, and the most frequent factor of CHF decompensation was AF. On hospital discharge, the drugs that improve the prognosis of CHF were prescribed at insufficient doses.
Virtual Memory Palaces

Published: June 2022

A person's memory often begins to degrade in older age, however the rate and degree of this degradation often varies among individuals. This suggests that there are outside factors to age that can prevent early memory regression. Memory palaces (MP), or the Method of Loci (MoL) technique, are a widely studied mnemonic used for centuries to facilitate the memorization of a wide variety of information. Virtual experiences that replicate memory palace learning have proven to have similar effects to traditional MoL-learning, especially in more immersive settings. Older adults trained to use MoL have shown increased recall of listed information, suggesting it as a mnemonic that can improve memory. Additions such as movement and music while using MoL have demonstrated positive results in older adults as well as providing a group environment for learning. However, many virtual MPs have yet to test other considerations that may make MoL more effective for recall. The visual aspect of virtual MPs has yet to be optimized by way of testing what visuals are truly important to improve recall. Using landmarks is common within virtual MP studies, but the significance of the landmark imagery itself has yet to be determined. Virtual environments that are personalized and meaningful to the MP user have yet to be compared to locations that have been learned recently. This thesis proposes a Virtual Reality (VR) experience design that can test all the above factors while maintaining critical components that will facilitate memory training in older adults in solo or quarantined situations. Using an immersive, customizable virtual environment and interactive waymarks, participants will be able to replicate the MP technique to improve recall, preventing memory degradation in old age through self-training.

Published: June 2022

Of the 6.3 million people under correctional supervision in the United States, almost two-thirds are on probation and parole. The growing trend toward community supervision has been accompanied by the development of problem-solving courts, the most well-known of which are drug courts. Although there is substantial research demonstrating the effectiveness of drug courts in reducing reoffending, there is more limited research on other types of problem-solving courts, such as reentry court. This study seeks to expand the current literature by surveying federal reentry courts across the United States. Survey questions concerned the primary goals of the programs, the biggest challenges, and the reasons for participant non-completion. In total, 64 reentry courts completed surveys. Results demonstrated that Risk-Need-Responsivity principles were important, but were not always prioritized over Good-Lives-Model principles. The importance rating for internal motivation was independent of the importance rating for external factors such as family and employment. Attributing high importance to successful completion of reentry court was associated with attributing high importance to the prevention of program attrition. Moreover, participant honesty and internal motivation were of high importance to respondents, as were team collaboration and relationship building. Implications and future directions are discussed.

Real estate consultants are economic units that establish a link between housing supply and demand and support the efficient maintenance of commercial operations in the housing marketing process. Real estate consultants experience many different problems during a relevant process similar to other units in the system. This study aims to define the problems faced by real estate consultants in the housing marketing process in a qualitative pattern. Using the interview technique, based on the data of 22 real estate consultants, the basic problems experienced in the housing marketing process can be classified under four headings: problems arising from the housing marketing process, problems related to the real estate consultancy profession, customer data storage, and customer communication.

This study is conducted with an aim to Diagnosis of invasive Mucormycosis on Histopathological examination at a tertiary referral hospital. Rhino cerebral Mucormycosis is the current life-threatening infection commonly affecting immunocompromised patients especially post COVID-19 within 6 weeks having poor glycemic control, Intravenous drug users, ICU patients, post chemotherapy, iron overload, persistent neutropenia and follow-up cases of hematological malignancies. It affects the nasal and paranasal sinuses by air-borne spores producing the infection. A prospective case series conducted at the department of pathology, KAMSRC ‘between’ May 1to September 30th 2021 with a study population of 27 cases. Variables included age, gender, and history of covid, duration and development of symptoms, Clinical presentation, clinical diagnosis, co-morbidities, histopathological examination and microbiological correlation. The most prevalent isolated agent is Mucor (48.1%) followed by Rhizopus (18.5%), Aspergillus (11.1%) and mixed mucor with aspergillus (11.1%).

A prospective case series conducted at the department of pathology, KAMSRC, reported 27 cases of post covid-19 Mucormycosis aged 30-68 years. Clinical features at presentation included unilateral facial pain with proptosis (80%), loss of vision, headache, nasal crusting, Cough with dyspnea and mild fever. All cases were admitted in ICU with severity in symptoms with 7 deaths recorded during treatment (25.9%).

Immunofluorescence with Robin blue/Calcofluor white stainfor fungal elements was also combined to highlight Mucor species.Fungal cultures were diagnostic for fungal elements obtained after 48hrs on Sabouraud’s/Potato dextrose agar(SDA/PDA). Three cases were negative for fungal elements withonly dense mixed inflammatory infiltrate admixed necrosis. Correlation with KOH mount & fungal culture on SDA/PDA showed 13 cases of mucor, 5 cases of rhizopus, 3 cases of aspergillus & 2 cases of mucor with aspergillus growth, 3 cases were negative with no fungal growth. Also correlated with the microbiology department where nasal crusting and nasal tissue was obtained for fungal elements for KOH wet mount and fungal culture. KOH wet mount microscopy revealed Broad aseptate hyphae with wide angle branching suggestive of Mucormycosis. Simultaneous analytical study of CBP showed raised total WBC counts in 4 individuals (19,620-24,670 cumm) with others having normal CBC.CRP was in the range of 32-68mg/dl with ESR 35-98 mm/hr.

: Understanding the mechanism of host innate immunity and specific preventive strategies are important for favorable prognosis. Histopathological examination aids in early diagnosis of Mucormycosis.
Atherosclerosis in coronary arteries and aorta by modified American heart association classification: An autopsy study
Authors: B Harveen , C Vijaya , M Smita
Published: June 2022

Ischemic heart disease following atherosclerosis is a leading cause of deaths among Indians. The study was formulated to assess the Histomorphological atherosclerotic changes in coronaries and aorta in autopsy by applying Modified American Heart Association Classification (AHA) among the autopsy cases received at SIMS & RC, Bangalore.

1. To evaluate the autopsies for atherosclerosis in coronary arteries and aorta. 2. To classify atherosclerosis in coronary arteries (right coronary, left coronary, left anterior descending) and aorta by Modified American Heart Association classification (Grade 1-8).

Autopsy was studied for 49 cases from June 2019 to August 2019. It was conducted by conventional method and heart was dissected along the flow of blood. Grossly macro-assessment was done and on histopathology examination microscopic assessment was done using Modified American Heart Association Classification.

A total of 49 cases were studied, of which 42 cases were male and 7 were females. Male to female ratio was around 6:1. Coronary showing major occlusion was Left Anterior Descending followed by Right Coronary and then Left Circumflex artery. Major number of cases were belonging to grade 4 (59.1%) followed by in grade 3 (38.7%). Calcification was noted in 6 cases (12.2%) and ruptured plaque in 4 (8.16%).

With the cardiovascular diseases attaining pandemic proportions, the study of atherosclerosis and its grading is the need of hour to estimate disease burden. Autopsy studies play a vital role in unraveling the spectrum and occurrence of atherosclerosis.

Authors: Kanchi Vijay Srinath , Kolambikar Ashok
Published: June 2022

India’s Education sector is in for a grand transformation thanks to the introduction of the National Educational Policy 2020. The present government is also focusing heavily on the country’s higher education sector and wants it to be on par with its international counterparts in terms of quality in research and publication. With this changed backdrop, the modern day librarians of HEIs are no longer reckoned as mere custodians and gatekeepers of traditional knowledge resources; they are vested with the job of educating the research scholars about research and publication ethics, citation styles, provide insights into free, copyrighted material and creative commons licensed content, online resources, check the research outcomes for plagiarism and play a significant role in the Academic Integration Committees of their institutions. This paper deliberates on the enhanced role of librarians as the knowledge resource managers in ensuring the quality standards in research and publication.
The Theandric Role of the Church in the Life of the World during, before and after COVID−19 Pandemic
Authors: Omollo Fredrick
Published: June 2022

The “earthly” Church is on pilgrimage and has the task of making disciples of all peoples (cf. Mt 28:19−20). She has her transcendental dignity, proportional to its representative (sacramental) essence and function as the universal sacrament of salvation. In the Christological perspective, the “earthly” Church carries out the redemptive and salvific work of Christ. On the part of the Church, this saving work is still relevant, polymorphic and incomplete, and sometimes also tainted by sin. For the Church is not identical with the Kingdom of God. Therefore, the current question remains how to realize the theandric nature of the Church in her mission in the current historical, social and cultural context? A particular drama in the implementation of the Church's mission is added today by the situation of the Covid−19 pandemic, which on the one hand contributes to hindering the exercise of a particularly liturgical function and, on the other hand, intensifies the process of impoverishment of people in many countries of the world. The new poor become an additional challenge for the Church in her charitable mission. The article has a dogmatic-pastoral character, and its main sources are post-conciliar documents and the latest statements of Pope Francis. According to the author, the Church, as a community of Christ's disciples, must learn from her Master to build interpersonal relationships in search of harmony with the world and at the service of humanity. Remembering the theandric nature of the Church can be very helpful in this task.
