EFFICIENCY OF HARDENING OF METALLURGICAL EQUIPMENT SPARE PARTS BY HARD ALLOY
Authors: Bystrov V. А.
Published: January 2019

Composite  materials  (CM)  are  widely  used  for  hardening  of  wearing parts operating at high temperature wear types. They are based  on  high-melting  hard  alloys,  as  which  are  used  carbides  of  transition  metals  of  IV – VI  groups A  determining  the  physics  of  high-temperature wear. For these purposes baked TiC of TN 20 type on the basis  of (Ti, Mo)C – Ni – Mo is used that has a ring structure preventing the  formation of complex alloyed structures on the bounda ry of solid particle-matrix. Due to the minimal solubility of the sintered hard alloy of  TN 20 type in the alloy-bond, at the interface of solid particle – matrix  practically does not stand out complex structural phases causing embrittlement and growth of residual thermal stresses and strains. It leads  to increased wear resistance and longer service life of hardened parts.  In order to increase the opera ting efficiency of metallurgical units due  to  hardening  of  spare  parts  with  a  composite  material  based  on  sintered hard alloy of the TN 20 type using electroslag surfacing (ESW),  a comprehensive program has been developed to control the efficiency  of hardening parts. In the management of hard alloy surfacing the special  attention  is  given  to  heat  and  high  temperature  wear  resistance  determined  by  the  set  of  CM  properties  of  solid  particles.  Therefore,  maintaining of high mechanical, thermal and energy characteristics of  carbides and decrease of the solubility of solid particles in a CM matrix  at surfacing is a priority for improving efficiency in hardening process  of spare parts. Integrated ESW management program for CM is based  on  effects,  aimed  to  prevent  the  formation  of  complex  alloyed  structures on surface of the solid section of particle-matrix; to reduce thermal stresses and deformations (leading to the cracks formation, chipping and deleting solid particles in abrasive wear) and to improve high  temperature wear resistance. Use of the developed control systems for  hardening  process  of  metallurgical  equipment  wearing  parts  has  significantly  increased  the  service  life  of  spare  parts  and  producti vity  of  the metallurgical units, which ensured a certain economic effect.

DETERMINING THE FORCES OF INTERACTION OF MAIN GEOKHODS SYSTEMS WITH GEO-ENVIRONMENT AND WITH EACH OTHER
Authors: Beglyakov V. Yu. , Aksenov V. V. , Kostinets I. K. , Khoreshok A. A.
Published: January 2019

The processes occurring during the geodetic excavation of underground excavations are characterized by the interaction of the elements of the geokhod with each other and with the geo-environment. The interaction process can be investigated in mathematical modeling, solving the problems of justifying the parameters of the drives and interacting forces, ensuring sufficient strength of the machine elements and the bearing capacity of the contour array. The proposed block-modular principles of constructing a mathematical model allow solving particular problems of the system and its individual elements. From the solution of particular problems, it is now necessary to proceed to the solution of the generalized model, using equivalent loads and reduced total moments (forces). The construction of a generalized model requires a number of assumptions, but its solution will reveal the interaction between the elements of the geokhod and the geo-environment, which is very relevant.

As an example, the solution of a particular problem is given-the determination of the value of the forces arising from the interaction of the blade of an external engine with the medium.

A list of assumptions is formulated that allow us to describe a general mathematical model of the interaction between the geo-environment and the geokhod, as well as the processes occurring during geodetic excavation of mine workings.
Inclusió educativa i aprenentatge-servei a l’àrea de Didàctica de l’Expressió Corporal

Published: January 2019

L'Aprenentatge-Servei (ApS) és una metodologia pedagògica experiencial i activa. Una de les seves principals virtuts és que fa efectiu el principi educatiu que diu que l'aprenentatge ha d'estar vinculat al medi social, físic i humà en què viu la persona que aprèn, qüestió essencial per poder dotar de significat real els aprenentatges. L’ApS el podem assimilar a un paraigua sota el qual s'aixopluguen altres estratègies, procediments i accions metodològiques. És a dir, el seu ús no soluciona una qüestió bàsica i pràctica com la d’organitzar ‘la classe de demà’; no és una estratègia concreta, és més aviat una forma d'entendre l'acció educativa. Des d'aquesta perspectiva, cal entendre’l com un paradigma global que impregna la nostra forma d'ensenyar, però que requereix d'altres estratègies per a la seva implementació. Aquest text presenta un projecte aplicat d'inclusió educativa realitzat a través d'ApS amb alumnat universitari del Grau de Mestre o Mestra d'Educació Infantil, executat a un  Centre d'Educació Infantil i Primària. En els primers apartats analitzarem la base conceptual de l’ApS, per continuar descriurem el projecte Patis Inclusius i finalment acabarem realitzant una avaluació del mateix.

Acceso a la universidad y equidad
Authors: Sacristán Vera
Published: January 2019

El sistema universitario ha ido evolucionando progresivamente hacia una configuración más amplia y equitativa, pero todavía subsisten una serie de desigualdades manifiestas. Además de analizar el importante crecimiento del acceso a la universidad en las últimas décadas, en el presente artículo se analiza si este crecimiento se ha producido o no de forma socialmente equitativa. Por un lado, se aborda si las desigualdades económicas y culturales de partida inciden no sólo en el acceso a la universidad, sino también en la elección de los estudios y en las condiciones de vida estudiantil de los universitarios. Asimismo, al examinar la igualdad de oportunidades en el acceso, el estudio considera también la cuestión desde el punto de vista de la igualdad de género, así como el efecto del incremento sustancial de los precios de las matrículas universitarias, entre otros aspectos. Estas desigualdades en el sistema educativo, pueden comportar no solo efectos en la equidad, sino un mal aprovechamiento del talento de una sociedad.

Published: January 2019

Several are the concomitant factors enabling the development of the knowledge transfer, first among all the awareness that university knowledge is at the basis of innovation and business productivity, generating relevant competitive advantages. Public policies have focused on fostering kind of mechanisms, both at national and European level. However, the knowledge transfer is a complex process, involving several actors and different objectives, often conflicting. Our review of the literature reveals that the obstacles to an effective and efficient knowledge transfer are numerous and of various nature, ranging from incentive system at individual level to process managing at institutional level as well as at national and European level. We focus on the tree main knowledge transfer mechanisms, namely licensing, patenting and start-up companies. Extant studies show that steps have been taken but there is still long way to go. Suggestions for policy makers and management are provided, and implications are discussed in the concluding section.

Virtuelle Inbetriebnahme im Takt
Authors: Lämmle Beat , Oppelt Mathias
Published: January 2019

Für die risikoarme, fehlerfreie und schnelle Inbetriebnahme von industriellen Anlagen und Maschinen spielt die virtuelle Inbetriebnahme zunehmend eine Schlüsselrolle. Der Test gegen ein virtuelles Modell (eine Simulation) ermöglicht einen umfassenden Test der originalen Automatisierungsprogramme vor Einsatz mit realem Equipment. Eine wesentliche Notwendigkeit ist die Verfügbarkeit von Modellen die das Verhalten der zu automatisierenden Maschine oder Anlage hinreichend genau abbilden. Häufig sind Modelle über verschiedene Simulationswerkzeuge verteilt, die unterschiedliche Aspekte modellieren und eine Co-Simulation wird erforderlich. Dieser Beitrag stellt eine neue Software-in-the-Loop Co-Simulationslösung vor die sich durch eine taktsynchrone Kopplung der beteiligten Werkzeuge im 1ms Takt auszeichnet. Hierdurch lässt sich eine sehr realitätsnahe komplette virtuelle Inbetriebnahme durchführen, die nur noch einen minimalen Hardwareaufbau erforderlich macht.

Published: January 2019

The study objective is to estimate treatment success of gamma knife radiosurgery (GKRS) in the patients with subtentorial cavernous malformation (CM) based on follow-up data and magnetic resonance imaging (MRI).

Materials and methods. The long-term follow-up of GKRS in 87 patients with CM in brain stem and cerebellum was obtained. The clinical outcomes were observed using phone-based SF-36 health status survey in 55 patients. MRI data was collected before and after GKRS within 1, 2, 3 and more years. The natural history of CM without GKRS were observed in 20 patients.

Results. The 1st year MRI observation after GKRS have demonstrated CM reduction in 66,6 % patients. At subsequent MRI-control the tendency of increase in number of CM, reacted on irradiation, and continuation of started processes of its sclerotization is revealed. The fast reduction of CM sizes was associated with lower risk of recurrent hemorrhages, that were observed in 3 patients with slow reduction. The CM reduction was also associated with good clinical outcomes, that was observed in 64,5 % patients.

Conclusion. The presence of CM reduction (72,4 %) and good clinical outcome in suggests GKRS as a frontline treatment modality in patient with subtentorial CM. In the cases of slow rate of treatment response and unexpired risk of repeated hemorrhage no mortality and significant disability were mentioned.

Authors: Kandyba D. V. , Babichev K. N. , Zenin A. V.
Published: January 2019

The study objective is to present a clinical case of using transradial access for embolization of an aneurysm of the basilar artery (BA) bifurcation. 

Materials and methods. A patient, 67 years old, sought medical help at the I.I. Dzhanelidze Saint Petersburg Research Institute of Emergency Medicine complaining of headaches. Computed angiography of the brain had shown a large aneurysm of the BA with an absolutely wide neck. Embolization of the aneurysm using stent assistance (Y-stenting) was performed with access through the radial artery. The results were compared to data from scientific literature (about 16 cases).

Results. Aneurysm embolization level was II or IIIb per the modified Raymond–Roy classification was performed. No complications were observed, blood flow in the radial artery was preserved. The patient was released on day 2 after the surgery. No signs of blood flow through the aneurysm were observed during control selective cerebral angiography 12 months later. According to literature data, transradial access is preferable only with pathology of the vertebrobasilar system, especially if standard access is impossible to form due to atherosclerotic damage of the femoral artery, angling of the aortic arch, and pathological vessel tortuosity.

Conclusion. Routine use of transradial access in surgery of pathologies of the cerebral flow is not justifiable. But in some cases, this alternative access can be more effective and safer compared to the standard access. The main advantages of this access are reduced rate of complications of arterial access and possibility of early patient activization.

The study objectiveis to report a case of mandibular ameloblastoma.

Materials and methods. A 30-year-oldfemale patient presented with swelling of the right mandibular region that appeared 8 months ago and has been slowly increasing. The patient had no other symptoms, such as pain, anesthesia, paresthesia, difficulty swallowing, mouth opening, speech disorders, fever, chills, or weight loss. Orthopantomography revealed pronounced bone resorption in the right portion of the mandibular body. Computed tomography showed a cystic cavity in this area. After incisional biopsy, the patient was diagnosed with ameloblastic carcinoma. We performed segmental mandibular resection and installed a reconstructive plate to restore mandibular integrity. We also performed selective cervical lymph node dissection (levels Ia and Ib).

Results.One yearpostoperatively, the results were considered aesthetically and functionally satisfactory.

Conclusion.We observed an aggressive disease phenotype with extensive localized bone destruction, typical of ameloblastic carcinoma. Extensive excision of the primary tumor and selective cervical lymph node dissection without radiotherapy ensured a relapse-free period during patient’s follow up.

Christian–Weber disease refers to the group of panniculitis, which present an inflammation of the subcutaneous adipose tissue with the involvement of neutrophils, white blood cells and histiocytics, which leads to fibrosis in adipose tissue and sometimes to granulomatous changes. Clinically this pathology manifests from the formation of nodes in the subcutaneous adipose tissue, which appear suddenly, sporadically in some areas or multiple, sometimes forming large aggregations (plaques) or strands, shaped like a rosary. Consistency of nodes initially soft, then compacted, can form adhesions with the skin, the skin over them is not changed initially, followed by a color change from bright pink to brown-purple. Ends the process of atrophy of the affected area, sometimes with a depression in the center. Localization sites in the body are different; they are placed often on the buttocks, arms and legs. The duration of the process of the skin varies from a few days to a few months, after involution of old nodes may appear new ones, it are the cause of increasing the duration of the disease, having a relapsing course. It can be rather difficult to do differential diagnosis, which requires a great deal of experience of experts and a team approach to the study and treatment of this pathology. To confirm the diagnosis requires a biopsy of the skin. Prognosis depends on the nature of the disease and timely diagnosis.
ANTY-COLONIAL DISCOURCE OF UKRAINIAN THINKERS OF THE LATE 19th AND THE FIRST THIRD OF 20th CENTURY
Authors: Hrabovskyj Serhiy
Published: January 2019

The problems of colonialism and post-colonialism are very important for the modern world. Postcolonial studios are one of the key components of intellectual discourse. However, most of them have a serious flaw, namely the reduction of the topic to the collapse of colonial expansion and colonial exploitation to racial and geographical factors. These studios are about as colonizers view Europeans, and as oppressed peoples of the colonies view residents of other parts of the world. These researchers also do not pay attention to the fact that the Russian Empire had a colony at one time, not in America or Africa, but most of its colonies were in Asia. In addition, the Russian Empire had colonies in Europe: Finland, part of Poland, most of Ukraine, and so on. In turn, the German empire held in colonial condition the part of Poland that belonged to it. In Europe, therewere other colonies of other states. Therefore, at the end of the 19th and in the first third of the 20th century, the concept of "colony of the European type" appeared in socio-political thought. Ukrainian thinkers of this age (namely, Julian Bachinsky, Ivan Franko, Lesja Ukrainka Sergey Mazlakh and Vasyl Shahray, Mikhaylo Volobuev and others) by using certain methodologies investigated various aspects of the existence of such colonies, primarily of the case of Ukraine. Bachinsky puts the focus on purely economic factors that determine the colonial status of Ukraine, Franco – on national-political, Lesja Ukrainka – on existential, Mazlakh and Shahray – emphasized the aggregate of national, political and economic. At the same time, none of them took as the basis of the ethnolinguistic factor, like some Ukrainian researchers of colonialism do now. The article focuses on the ideas of Mikhaylo Volobuyev, which combine economic, political, socio-cultural and existential factors. Volobuyev, in addition, thoroughly criticized the substantial limitations of the racial-geographical approach to the problem of colonialism. Many of his ideas are relevant to modern challenges, others need rethinking in the context of the mutual struggle between different projects of globalization. Thus, in Ukraine at the end of the 19th century and in the first third of the 20th century there was a powerful intellectual direction of anti-colonial socio-political thought that did not reduce the problem of colonialism either to the racial factor, or to the geographical, or to the ethno-linguistic one. The author believes that such an integrated, multi-factor approach to the problems of colonialism and vision of overcoming the colonial heritage is the most urgent one. Therefore, it is expedient and necessary to appeal to the heritage of Ukrainian thinkers who turned to anti-colonial discourse.
UKRAINIAN SCIENTIST PAVLO CHUBYNS’KYY IS A REPRESENTATIVE OF THE NATIONAL ELITE

Published: January 2019

On the example of the way of life and scientific work of P. Chubyns’kyy, the article raises the question of the role of the national-intellectual elite and its influence on the social and political life. The importance of the scientific heritage of the outstanding Ukrainian scientist, folklorist, ethnographer, poet and public figure Pavlo Chubyns’kyy is highlighted. It is emphasized that Pavlo Chubyns’kyy's scientific achievements became a model for many researchers in studying the national culture of Ukrainians and laid the foundation for Ukrainian studies. P. Chubyns’kyy was the bearer of national-cultural ideas and values of Ukrainians. It is noted that Chubyns’kyy is the author of the Ukrainian source fund of ethnography, folklore studies and jurisprudence. The scientist wrote a poem, which later became the National Anthem of Ukraine. It is concluded that the scientific value of his legacy is that for the first time, on the basis of complete and comprehensive studies, Pavlo Chubyns’kyy made a comprehensive analysis of the Ukrainian people in all its manifestations - social, family, spiritual, cultural and linguistic contexts. P. Chubyns’kyy scientifically substantiated the integrity of Ukraine and the identity of the Ukrainian people. Pavlo Platonovych showed by his work the originality and richness of cultural heritage of Ukrainians, the uniqueness and beauty of the folk word. The scientific publication of Chubyns’kyy's "Proceedings of the Ethnographic-Statistical Expedition in the West-Russian Region" is the result of many years of titanic work. His public speeches, printed articles, substantiated scientific positions are capable of effectively influencing public opinion. After all, Chubyns’kyy belonged to the national-intellectual Ukrainian elite, who comprehended the greatness of folk culture and the uniqueness of the national life of Ukrainians. А real patriot could work so persistently and selflessly, a man of high culture and a civic position, enthralled with his idea. No wonder that his publications and publications became a model in scientific researches of the XIX century and are a huge contribution to the study of Ukrainian national culture. The scientist-Ukrainian connoisseur was aware of the value of what he was doing, and therefore his words were prophetic: "I will not waste my strength / And I will see my harvest." These words prove that he, with his life, professionalism, life position, sacrificed and persistently worked for the self-affirmation of Ukrainians as a self-sufficient nation with its unique culture and language. The great figure of Pavlo Chubyns’kyy, his life path, organizational skills, patriotism, scientific work is an example of the majestic figure of his time and a worthy representative of the Ukrainian national elite.

Published: January 2019

Background. Despite signifcant progress in the feld of coronary interventions, chronic total occlusion (CTO) represents a signifcant challenge for interventional cardiologists.

Aim. To develop the score, able to predict technical success of CTO PCI and facilitate the choice of recanalization strategy.

Methods. A total of 665 CTO patients who underwent 681 PCI in the period from 2014 to 2018 in Meshalkin National Medical Research Center were included in this study. Clinical and angiographic characteristics were analyzed. 477 CTO PCI were randomly assigned to the derivation set, 204 CTO PCI – validation set. The prognostic model was developed by assigning a score for each independent predictor of procedural failure in accordance with beta coeffcients and summing up all scores.

Results. Procedural success was 76.7%. Five predictors of procedural success were included into the fnal multivariable model: bending (1 score), calcifcation (1 score), ambiguous stump (1 score), “donor” artery disease (1 score), non-RCA CTO (0.5 scores). Based on these predictors, 4 categories of CTO complexity were highlighted: 0–1 scores (easy), 1–2 scores (intermediate), 2–3 scores (diffcult), > 3 scores (very diffcult). The score demonstrated a good discriminatory ability (AUC 0.709, 95% CI 0.658–0.760). According to the novel score retrograde approach may have an advantage in patients with a > 3 scores, which corresponds to the "very diffcult" class of complexity.

Conclusion. The novel score can be used in clinical practice for predicting the success of CTO PCI and determining initial crossing strategy.

Published: January 2019

Background. The work environment represents the environment where employees perform their duties, complete the set tasks. This environment involves a variety of factors (sanitation, hygiene, organizational, psychological, etc.). According to the ISO 9001:2015 requirements, the organization must identify, create, provide and maintain the environment for the operation of the processes, as well as to establish, implement, maintain and continuously improve the work environment. Therefore, employees envisage of the work environment is an important source of information for the quality management system, aimed at improving the customers’ satisfaction.

Aim. To study the opinion of the personnel about the work environment of the tertiary cardiovascular healthcare center.

Methods. The object of the study is the working environment of the medical institution, the subject of the research is the factors constituting the work environment. The sampling unit is the employee. The study was performed in the Research Institute for Complex Issues of Cardiovascular Diseases. The research was carried out according to the original questionnaire by the method of sociological survey of personnel. All the subjects were interviewed using the original questionnaire. The questionnaire is divided into several domains including employment terms, mental health and psychological climate, duties and work management.

Results. The gaps limiting the formation of the positive work environment have been determined after the baseline survey. 21.6% of the employees were not satisfed with the working conditions in general, and 27.1% – with the labor organization. 32.3% of the employees pointed low team cohesion, and 28.6% of the respondents indicated low organization cohesion. The statistically signifcant changes in the personnel responses to the most of the factors constituting the work environment have been traced followed the targeted activities carried out over several years. Thus, the proportion of positive answers on the compliance of the workplace with hygiene requirements (by 9.3%) and on the comfort of being at the workplace (by 13.9%) increased. The number of the employees satisfed with working conditions increased (by 9.8%). The proportion of employees satisfed with labour management, their duties and tasks improved as well. The development of the personnel-oriented management in the organization is associated with the tendency towards the team cohesion in the center’s divisions. However, the satisfaction of the personnel with the relations in the team remained similar as in 2012.

Conclusion. The study reports the opinion of the healthcare personnel on the work environment and forms the basis for the further improvements and implementation of the personnel-oriented management system.

Published: January 2019

Aim. To determine the relationships between the prevalence of certain work stress components and coronary artery disease in men of working age in the open population model of the medium-urbanized Siberian city (Tyumen).

Methods. A single-step epidemiological study was performed using the open population model with a representative sample of male adults (25–64 years) living in the Central Tyumen Administrative District. The subjects were stratifed by age (1000 men, 85.0% response rate). The data on coronary artery disease (CAD) were collected with the standard methods commonly used in the epidemiological studies. Work stress was determined with the questionnaire used in the WHO MONICA psychosocial program.

Results. Over 85% of men showed signifcant changes in work during the last year in the male unorganized population of the mid-urbanized Siberian city. Lower responsibility and workload, as well as an increase in the negative attitude towards work have been found in male adults with CAD aged 25–64.

Conclusion. The single-step epidemiological study with the open male population model of the mid-urbanized Siberian city showed the presence of the associations between the prevalence of CAD and some work stress components (physical activity and work responsibility within the last 12 months). The obtained results can be furtherly used for the development and implementation of socially oriented comprehensive prevention programs aimed at improving work environment for the personnel, including both, healthy subjects and working age men with CAD.

Authors: Grigoryev E. V. , Shukevich D. L. , Matveeva V. G , Kornelyuk R. A.
Published: January 2019

Aim. To defne the role of myeloid-derived suppressor cells in the development of persistent multiple organ dysfunction followed cardiac surgeries with cardiopulmonary bypass.

Methods. 40 patients who have undergone cardiac surgery were included in the study. Granulocyte myeloid-derived suppressor cells (G-MDSC) were defned as cells with the HLA-DR– / CD11β+ / CD15+ / CD33+ phenotype, and monocytic MDSC (M-MDSC) as cells with the HLA-DR– / CD11β+ / CD14+ / CD33+ phenotype using ﬂow cytometry. Levels of cytokines, IL-1β, IL-6, TNF-α, and IL-10 were measured with an enzyme immunoassay. All patients were assigned to three groups: Group 1 – patients with the uncomplicated postoperative period (n = 14), Group 2 – patients with non-persistent MODS and its early resolution (n = 16), and Group 3 – patients with persistent MODS at day 7.

Results. We observed an increase in M-MDSCs and G-MDSC at day 1 following cardiac surgery. The most pronounced increase was found in monocytic-myeloid derived suppressor cells, i.e. an 8-fold increase in M-MDSCs in all study groups at day 1 after surgery. The number of M-MDSCs remained high in patients with persistent MODS at day 7 after cardiac surgery. Levels of IL-6 and IL-10 increased at day 1 after surgery. IL-6 reached its peak level, signifcantly exceeding baseline levels. By day 7, blood levels of all cytokines have decreased, except IL-10 levels, which remained above the baseline in patients with persistent MODS.

Conclusion. An increase in M-MDSCs and elevated serum levels of the anti-inﬂammatory cytokine IL-10 have been found in patients regardless of the presence or absence of the complications in the early postoperative period after cardiac surgery with cardiopulmonary bypass. Persistent MODS with the SOFA scoring > 5 scores at day 7 after cardiac surgery, is associated with an increase in M-MDSCs and elevated levels of the anti-inﬂammatory cytokine IL-10, related to higher rate of hospital infections, prolonged intensive care unit stay and higher mortality.

Aim. To characterize the inflammatory process in gastric mucosa among adolescents with chronic gastritis in different variants of its bacterioviral infection.

Materials and methods.Clinicoanamnestic, laboratory, endoscopic and morphological examination of 200 adolescents (age range 12–18 years) with chronic gastritis was carried out. In all patients, clinicoanamnestic data, standard laboratory study, esophagogastroduodenoscopy, gastrobiopsy followed by morphological analysis with visual analogue scale were assessed. According to the results of examination, all adolescents were divided into 4 groups depending on the character of bacterioviral infection of gastric mucosa.

Results. No statistically significant differences were detected while comparing the rate of clinical manifestations of pain abdominal, dyspeptic, intoxication and asthenovegetative syndromes as well as changes, revealed in laboratory and ultrasound studies in the above mentioned groups of adolescents. Maximal presentation of macroscopic and pathohistological changes was registered in patients of group 4 (association between colonization of GM with highly pathogenic Hp strains and EBV persistence).

Conclusions. The character of bacterioviral infection of gastric mucosa significantly determines the manifestation degree and activity of inflammatory process. The least degree of manifestation and activity of inflammatory process is registered when mucosa is colonized by low pathogenic Hp strains. Maximal presentation of macroscopic and pathohistological changes in the gastric mucosa is registered in adolescents with associated infection by high pathogenic Hp strains and Epstein-Barr virus. It is manifested by domination of marked and highly active inflammation and appearance of the signs of mucosal atrophy of gastric body and antrum.

Bu
çalışmanın amacı tarım işletmecilerinin girişimci olma kararlarını etkileyen
faktörlerin belirlenmesidir. Bu amaçla, Konya ili Ereğli ilçesinde tabakalı
tesadüfi örnekleme yöntemine göre belirlenen 98 tarım işletmecisiyle anket
yapılarak girişimciliği etkileyen faktörler doğrusal regresyon ile analiz
edilmiştir. Çalışmada bağımlı değişken olarak girişimcilik katsayıları modele
alınmış, bağımsız değişkenler olarak ise arazi miktarı, aktif sermaye,
gayrisafi üretim değeri, erkek işgücü birimi (EİB), üretici yaşı, sigorta
yaptırma, net kar ve eğitim değişkenleri modele dahil edilmiştir. Modelin
açıklama gücü R2 %77.50 olarak belirlenmiştir. Modelde yer alan tüm
değişkenler t testi sonuçlarına göre istatistiki olarak anlamlı belirlenmiştir.
Bu sonuçlara göre; dekara düşen aktif sermaye miktarı ve yaş değişkenlerinin
işaretleri negatif, arazi miktarı, gayrisafi üretim değeri, EİB, sigorta
yaptırma, net kar ve eğitim parametreleri ise teoriye uygun olarak işaretleri
pozitif belirlenmiştir. Sonuç olarak, eğitim faaliyetlerinin girişimcilik
düzeyini artırdığını ve genç yaştaki üreticilerin daha fazla girişimcilik
özelliklerine sahip olduğunu ortaya çıkmıştır. Bu nedenle genç çiftçilere
eğitim faaliyetlerinin verilmesi, Küçük Ölçekli Tarım İşletmeleri (KOTİ) ve
teşvikler gibi projelerin desteklenmesi önerilmektedir.

The municipality of João Pessoa and the south coast of Paraíba, admittedly, is a tourist destination for sun and sea. It has a geomorphological, geological, pedological and hidrological heritage still little studied for geotourism purposes, whose contribution of this paper is to encourage discussions about this niche, yet incomplete, tourism, notably in the Paraíba State. The preliminary aim is to suggest potential sites that reflect the geodiversity of the area, with the aim of mapping the future of it, resulting the elaboration of a Geoturistic Guide of this coastal area. The geosedimentary history of the urban site of area dates back to the late moments of the separation of the supercontinent Pangea, forming the Paraiba basin. The urban development of geotourism in João Pessoa and surrondings is a dynamic way to publicize their geoheritage to a greater number of people, whether tourists or not, for it geoconservation. This practice still keeps its infancy, and the inventory of this geoheritage, as well as biotic and geomorphological heritage, with the intention of spreading the geosciences, it is necessary and is of huge importance to urban planning and management.

Published: January 2019

This study focused on examining the spatial characteristics and the patronage pattern of attractions and eco-tourism products in Enugu State. Primary and secondary sources of data collection were used to elicit information for the study. The primary sources involved the use of questionnaire survey, interview sessions guided by participatory rural appraisal technique, telephone survey, direct field observation and the use of Geographic Information System techniques. The secondary sources involved the use of documented information in textbooks, journals and registry of eco-tourism attraction across the study area. Findings from the study indicate that forty-one (41) operational ecotourism attractions exist across the study location with the result of the nearest neighbor analysis of 0.93 revealing that ecotourism attractions were randomly distributed across the study area. The study also observed that a total of 6,360 visitors visited and patronized the attractions between 2013 and 2017 with domestic eco-tourists having 56% of the entire visits to the attractions while visits by international eco-tourists recorded 44% of the entire visits. Based on the findings, the study recommended that major stakeholders in the tourism industry (government, non-governmental organizations and host communities) should collaborate and corporate to create an enabling environment for more investment opportunities and organize more ecotourism activities in the area. The study also recommended that managers of ecotourism attractions should employ modern marketing strategies to help create more awareness about the ecotourism attractions and its facilities to the entire world.

Published: January 2019

Due to the rapid expansion and associated construction of civil engineering structures on the Federal University of Technology, Akure (FUTA) campus, there arose an urgent need for an engineering geological mapping of the underlying soils (residual soils). Generalized geological mapping revealed four types of basement rocks namely migmatite-gneisses, granites, quartzites and charnockites. Results from the fifty (50) soil samples from twenty-five test pits collected all over the spread of the campus coverage of 6.4 km2revealed that the campus is underlain by soils of granular and clayey composition, generally lateritic, having reddish to brownish colour. Engineering geological tests such as natural moisture content, particle size analysis, consistency limits, California bearing ratio and consolidation were carried out on the soils following standard procedures revealed that the values of natural moisture content do not generally follow a consistent pattern and varied from location to location. The grain size characteristics curve, displayed 84% and 16% subsoils are of well graded and poorly graded type respectively. The soils were grouped into CL (low plasticity), CI (medium plasticity) and CH (high plasticity) from consistency limits results. Compaction characteristics of the subsoils revealed 36% and 64% representative of fair to good and poor to very poor foundation materials respectively. Soils with settlement rates greater than 1mm/year were designated as high settlement subsoils. 72% and 28% of the subsoils fell into hard to stiff and soft categories from the shear strength characteristics respectively, and classified as c-ø soils. California Bearing Ratios values range from 10 – 70, indicating their suitability for pavement construction. Conclusively, areas underlain by migmatite-gneiss and charnockite-derived soils, and granite and quartzite-derived soils possessed low and high strength characteristics respectively which can be attributed to their textural characteristics. The subsoils of the entire campus spread are however capable of bearing very substantial loads.
