Authors: Toptan Müslüm , Cadirci Dursun , kocakoglu senay
Published: February 2021

Aim: Red eye, a frequent cause of presentations to ophthalmology
clinics, is an important indicator of ocular inflammation. Although the
prognosis is generally good and self-limiting, it is possible to
distinguish possible serious conditions and prevent important situations
such as blindness, with detailed examination and correct treatment
approach. The purpose of this study was to evaluate patients with red
eye presenting to the eye diseases clinic in terms of clinical and
sociodemographic characteristics. Material-method: The records of
patients presenting to the Şanlıurfa Harran University Hospital
Ophthalmology Clinic with red eye were investigated retrospectively.
Diseases causing red eye were classified according to the International
Classification of Diseases (ICD 10) coding system. Demographic
characteristics such as age and sex and clinical findings were examined.
Results: A total of 2625 patients, 1775 males (67.61%) and 850 females
(32.38%), who presented with red eyes, were evaluated. The incidence of
viral conjunctivitis, the most frequently observed condition in patients
presenting due to red eye, was 15.08% (n=396). The most common cause of
red eye resulting in decreased vision and increased intraocular pressure
(IOP) was acute angle closure glaucoma (AACG). The most common symptom
was stinging-burning (70.36%), and the most frequent finding was
follicular hyperplasia (74.17%). Five hundred and seventy-one (21.75%)
patients who applied to the clinic with red eye had previously applied
to a family physician and 289 patients (11.0%) to an emergency
physician. Conclusion: Although prognosis is usually good in red eye,
and the condition is self-limiting, the detection of serious conditions
through a detailed history, examination, and therapeutic approach can be
enhanced with early and appropriate intervention. In addition to family
physicians and emergency physicians, the first to examine patients with
red eye, important morbidities such as blindness can also be prevented
by increasing the awareness of ophthalmologists and cooperation between
these.

Published: February 2021

Management of patients with acute type A aortic dissection (ATAAD)
presenting with cerebral malperfusion due to carotid artery obstruction
is still a major challenge and often associated with poor prognosis
despite successful surgical aortic repair, due to prolonged cerebral
perfusion deficit. Here, we present the first report regarding
successful percutaneous recanalization of an internal carotid artery
occlusion in the setting of an ATAAD prior to open surgical aortic
repair with excellent clinical outcome after three year follow-up,
including almost full neurological recovery.

AIM Using three-dimensional ultrasound speckle tracking echocardiography
(3D-STE) to evaluate left ventricular (LV) function in patients with
triple vessel coronary artery disease(TVD) without myocardial
infarction. METHODS Sixty patients with TVD without myocardial
infarction were divided into two groups according to the results of
coronary angiography. Group B (n=31)：50%≤the stenosis rate of all
triple vessel coronary artery＜75%; Group C (n=29)：the stenosis rate
of all triple vessel coronary artery≥75%. Thirty healthy subjects were
recruited as the group A. We measured LV end-diastolic and end-systolic
volume (LVEDV, LVESV) and LV ejection fraction (LVEF) using real-time
dynamic three-dimensional echocardiography. The 3D-STE parameters of LV
included global longitudinal strain (GLS), global area strain (GAS),
global radial strain (GRS) and global circumferential strain (GCS). The
correlation between 3D-STE parameters and NT-proBNP were analyzed by
Pearson linear correlation analysis. RESULTS In group C, LVEDV and LVESV
were significantly increased (all P＜0.05), while LVEF, GLS, GRS, GCS
and GAS were significantly decreased compared with groups A and B (all
P＜0.05). In groups A and B, there were no statistical differences in
LVEDV, LVESV and LVEF. However, GLS, GCS and GAS were lower in group B
than in group A (all P＜0.05). The correlation analysis showed a
negative correlation between the absolute values of GLS, GRS, GCS, GAS
and NT-proBNP in group C
(r=-0.866、-0.587、-0.428、-0.600，P＜0.001、P=0.001、P=0.020、P=0.010).
CONCLUSIONS Our study shows that 3D-STE can evaluate the LV function in
patients with triple vessel coronary artery disease without myocardial
infarction through multiple strain parameters.

Published: February 2021

Objectives We set out to create Consensus Guidelines, based on current
evidence and relative risks of adverse effects and the costs of
different treatments, that reflect the views of the British Rhinological
Society (BRS) Council on where the use of biologics should be positioned
within treatment pathways for CRSwNP, specifically in the setting of the
National Health Service (NHS). Methods An expert panel of 16 members was
assembled. A review of the literature and evidence synthesis was
undertaken and circulated to the panel We used the RAND/UCLA methodology
with a multi-step process to make recommendations on the use of
biologics. Setting and participants N/A Results Recommendations were
made, based on underlying disease severity, prior treatments and
co-morbidities. A group of patients for whom biologics were considered
an appropriate treatment option for CRSwNP was defined. Conclusions
Although biologics are not currently available for the treatment of
CRSwNP, the BRS Council have defined a group of patients who have higher
rates of ‘failure’ with current treatment pathways, higher resource use
and are more likely to suffer with uncontrolled symptoms. We would urge
NICE to consider approval of biologics for such indications without
applying further restrictions on use.

The phenomenon that occurs in modern society is starting tourism activities so that there must be a strategy that is in accordance with the times and can be used as management and development of tourism potential by utilizing digital media as a media for branding which is part of marketing communication. The purpose of this study is to determine the implementation of media branding strategies in the development of the tourism sector in Pesisir Barat Regency as an international tourist destination, supporting and inhibiting factors that affect media branding in the development of the tourism sector, as well as the impact of the Covid-19 pandemic on the tourism sector in Pesisir Barat Regency. This type of research is a descriptive study with a qualitative approach. The results showed that the implementation of the media branding strategy for the development of the tourism sector in Pesisir Barat Regency as an international tourist destination, namely the setting of annual goals, its implementation is still minimal because it is not well directed as well as the use of less massive media in an effort to branding tourism; policy formulation, namely the existence of a decree on the division of tourism villages; motivating workers with the efforts that have been made such as mutual encouragement, coordination, and evaluation in private meetings or invitations; lack of allocation of qualified human resources in the IT field. Furthermore, the supporting and inhibiting factors that influence the branding media are the role of the community which indirectly participates in branding the existing tourism potential as well as the limited quality and quantity of human resources and the lack of the role of the government. Then the impact of the Covid-19 pandemic resulted in a decrease in the number of tourists and the cancellation of events that had been prepared
Sosiaali- ja terveydenhuollon kokonaisarkkitehtuurin kypsyysmallivertailu: näkökulmia kansalliseen ohjaukseen
Authors: Vuokko Riikka , Palojoki Sari
Published: February 2021

Sosiaali- ja terveydenhuollon alueella kokonaisarkkitehtuurin (KA) tuloksia ei ole vielä laajasti arvioitu, vaikka menetelmää on sovellettu jo lähes parin vuosikymmen ajan. Tässä tutkimuksessa tarkastellaan tiettyjä keskeisiä kokonaisarkkitehtuurin kypsyysmalleja. Tutkimuksen lähtökohtana oli olettamus, että KA-kypsyyden kasvu parantaa julkishallinnon ohjausta. Tutkimusmenetelmänä käytettiin kuvailevaa kirjallisuuskatsausta. Tutkimus tuotti vertailun neljästä kypsyysmallista: EAMM, DyAMM, MIT CISR ja SAMM. Lisäksi tarkasteltiin kahden mallin, DyAMM ja SAMM arviointipiirteitä. Tämän tutkimuksen tulokset osoittavat, että KA-kypsyysmalleja on tutkittu vähän. Teoreettisen perustan heikkous onkin haaste KA-kehittämiselle ja kypsyysarvioinnille. Malleissa tunnistettuja ulottuvuuksia voitaisiin kuitenkin hyödyntää tehokkaammin julkishallinnon KA-ohjauksessa. Kypsyysmallien kehittäminen edellyttäisi jatkotutkimusta, jossa teoreettinen tutkimus yhdistettäisiin mallien testaamiseen tapausaineistolla. Malleja tulisi kehittää tutkimusnäyttöön perustuen eikä pelkästään yksittäisten hankkeiden perusteella. Tällä tavalla kypsyysmallit tuottaisivat luotettavaa ja paremmin kohteeseen soveltuvaa arviointia myös julkishallinnossa ja sen ohjauksessa.

Psykiatrisia avohoidon palveluita on digitalisoitu aktiivisesti jo ennen koronavirusepidemiaa, mutta varsinkin epidemian käynnistymisen jälkeen etäasioinnin merkitys on kasvanut. Tämän poikkileikkaustutkimuksen tavoitteena oli selvittää, kuinka koronaepidemia on vaikuttanut psykiatristen avohoitokäyntien toteutusmuotoon ja kuvailla psykiatristen erikoissairaanhoidon palveluiden johtajien kokemuksia etäasioimisesta. Tutkimuksen tuloksia voidaan hyödyntää psykiatristen avohoitopalveluiden arvioinnissa sekä kehittämisessä sekä jatkotutkimuksessa.

Kyselyaineisto kerättiin osana COVID-19 tilannekuvaseurantaa sähköisellä kyselylomakkeella koronaepidemian käynnistymisen jälkeen toukokuussa 2020. Kyselyssä oli sekä strukturoituja että avoimia kysymyksiä. Kyselyyn vastasi 39 aikuispsykiatrian, nuorisopsykiatrian ja lasten psykiatrian toimialojen esimiestä ja johtajaa 19 eri sairaanhoitopiiristä. Kvantitatiiviset kysymykset avohoitokäyntien toteutusmuotojen määrästä raportoitiin prosenttiosuuksina ja avointen kysymysten vastaukset analysointiin induktiivisella sisällönanalyysillä.

Tulosten perusteella etäasioinnin suhteellinen osuus kaikista asiointitavoista kasvoi voimakkaasti koronaepidemian käynnistymisen jälkeen. Psykiatrisista avohoitokäynneistä toteutettiin puhelimitse tai etäyhteydellä tammikuussa 9% ja toukokuussa 48% (39 prosenttiyksikön kasvu). Etäasiointia haastoivat välineiden riittämättömyys ja toimimattomat ohjelmat, asiakkaiden puuttuvat laitteet, yhteydet ja tilat, etäasioinnin soveltumattomuus kaikkeen toimintaan, ammattihenkilöiden ja asiakkaiden negatiivinen asennoituminen, riittämätön osaaminen etäasioinnin käyttöön ja organisatoriset ongelmat. Etäasiointia edistivät asiakkaiden ja ammattihenkilöiden myönteinen asenne ja ilmapiiri, koronaepidemian aiheuttama tarve etäasioinnille, etäasioinnin soveltuvuus ja tuttuus psykiatrisissa avohoitopalveluissa, asiakkaiden aikaisempi tuntemus, pitkät välimatkat, toimivat etäverkostot ja ajansäästö, toimiva tekniikka, ohjelmistot ja välineet sekä riittävä tuki.

Etäasiointi on mahdollistanut epidemiatilanteessa psykiatristen avohoitopalveluiden tarjoamisen niille asiakkaille, joille etäasiointi soveltuu ja jotka kykenevät etäasiointiin. Etäasioinnin merkitys koronaepidemian aikana on ollut tärkeä, mutta etäasioinnin lisäksi on tärkeää innovoida ratkaisuja, kuinka psykiatrisia avohoitopalveluita voitaisiin toteuttaa niille asiakkaille, joille etäasiointi ei syystä tai toisesta sovellu.

Published: February 2021

Antimicrobial peptides (AMPs) recognized as host defense peptide (HDPs), have achieved considerable attention during last two decades as potential components of the instinctive immune system. Amongst the insects over casted for AMPS the hymenopterans comprising of ants have been identified for possessing potent antimicrobial peptides, those are small linear peptides. An investigation was taken up to screen for antimicrobial peptides collected from ants thriving in Forest Plantation in Hijli of Midnapore District, W.B. Three species of ants, members of the family Formicidae, were collected for in vitro antimicrobial activities of the whole body extract. These were tested by in the 10% of acetic acid solution using the Kirby-Bauer disc diffusion method against test microorganism viz. Escherichia coli, Staphylococcus mutans, Vibrio cholarae and Candida albicans. A strong antimicrobial activity was noted in all the extracts against all the microorganisms. The Spectrophotometric scanning was carried out to confirm the presence of peptides. TLC and HPLC were done. The result revealed that all the three species of ants exploited in this study were found to be a promising source of antimicrobial peptides.
Characterization of Olive (Olea Europaea L.) Genetic Resources via PCR-Based Molecular Marker Systems
Authors: Galatali S. , Abdul Ghafoor N. , Kaya E.
Published: February 2021

Olea europaea L., which is one of the ancient culture species cultivated in the Mediterranean area, has approximately 1200 cultivars. Its wild thype forms from O. europaea subsp. europaea var. sylvestris and its culture type forms from O. europaea subsp. europaea var. europaea. Olive cultivation is multiplied by grafting or cutting whereas wild type olive seedlings derived from seeds of O. europaea L. var. sylvestris. Because they have very big level heterozygosities, the genetic diversity of olive cultivars is quite high that they are predominantly allogamus. This genetic variability causes many confusions for identification of olive cultivars and since both oil quality and olive productivity are traits inherited to a variety, it is urgently needed to solve characterization and evaluation of olive genetic resources. The molecular marker systems are independent from environmental factors and effective technology to both detect homonymous and synonymous of cultivars and identify olive varieties. The current review is aimed to present molecular marker systems for identification and characterization of olive cultivars and emphasize their application for conservation of olive germplasm.

Examples of the nomenclature enzymes of all known classes with intrinsic lectin properties are represented, described and ordered. Such bi/multifunctional enzymes (enzybiotics) act as communicative agents, possess independent carbohydrate binding motifs, domains, epitopes or modules within subunit/molecule or supra-molecular assembly (free or solid-phased). Lectin part serve as modulator, switch and/or navigator of the whole resulting pattern enzyme (involving both catalytic center and lectinic sites) specificities toward targets. These enzybiotics (native and recombinant) as well as lectinbiotics (lectin-biotics) with intrinsic enzyme activities and high communicative potential possess promising broad prospects in food industry, medical biotechnology, prophylaxis and therapy. Among examples there are probiotic lectin enzybiotics (mainly from bifidobacteria and lactobacilli) that can serve perspective metabolite postbiotic systems for support or correction of the healthy individual or the patient mucosal open cavity biotope pathological status, respectively. Lectin-enzyme relationships improve platform for constructing advanced autoregulated systems influencing interactome at all levels of the organism. They support a lot of possible innovations in industrial biotechnology and medicine.

Density Functional Theory (DFT) plays a vital role in the study of organic materials. Lawsonia inermis is identified among the promising organic candidates to replace toxic and expensive solar cell material. The present study reported step by step computational procedure used to exposed the beauty of the organic solar cell candidate using Gaussian09 software. Stability check, optimization at different basis set, Homo-Lumo, band gap and Infrared spectrum (IR) at different medium were reported. It was found that the ground state energy, Homo-Lumo at both vacuum and Medium, band gaps, were found to be -16607.3717574 eV, -7.431 eV -3.584 eV (Vacuum) -7.311 eV -3.515 eV (Medium) 3.847 eV (Vacuum) 3.79 eV (Medium) respectively. For the IR it was found that there is shift and increase in the intensity due to the solvent effect on the material. These results were compared with the literature and are in agreement. It can be concluded that the Lawsonia inermis at solvent medium can enhance smooth and easier electron hole transport by looking at the band gap and hence it can and will be a good candidate organic material for solar cell production.
Energy and Exergy Analysis of an Organic Rankine Cycle used for Ylang-Ylang Essential Oil Distillery Waste Heat Recovery for Power Production in Anjouan Island
Authors: Ahamadi Malik El’Houyoun , Rakotondramiarana Hery T.
Published: February 2021

In the ylang-ylang essential oil distillers in Anjouan Island, the used energy is 100% firewood biomass. A large amount of this energy is dissipated in the environment just in the combustion chamber itself. As it turns out, the flue gases in this process take away the most part of it. Thus, in a process of energy efficiency of stills, the present work aims at assessing the possibility to convert the residual heat from the process into electricity. For that purpose, energy and exergy modeling of an organic Rankine cycle was implemented. It was found that a large amount of exergy is destroyed in the evaporator. Similarly, it emerges that the exergy efficiency of the cycle depends on the inlet temperatures of the exhaust gases in the evaporator and on the inlet pressure of the working fluid in the turbine, and that it is much better for low exhaust gas temperatures. At these low values of gas temperatures, it appears that the improvement in exergy efficiency and energy efficiency are linked to the increase in the inlet pressure of the working fluid in the turbine. It follows from the obtained results that the discharged hot water and the residual heat of gases having temperatures ranging from 180°C to 300 °C, could be used for power production which can reach electrical powers between 1.4kW and 4.5kW
Spin Quantization in a Classical Model
Authors: Selke David L.
Published: February 2021

The origins of quantum theory lie in a failure to explain certain phenomena using classical theory. But despite its adoption, quantum theory abounds with concepts described as “weird” or “spooky.” Even Feynman said that no one understands quantum theory. We revisit the Stern-Gerlach experiment that gave rise to the concept of spin and its quantization from a classical point of view. We present a simplified model of the classical electron which has two stable states which separate into two beams in the presence of an inhomogenous magnetic field.
Explaining the Nature of the Mass m of Submicroparticles and the Phenomenon of Mass Variation with Velocity V in Ether
Authors: Has Ioan , Miclaus Simona , Has Aurelian
Published: February 2021

A brief history of mass nature is presented, including formulas for mass variation with velocity V. A new mass hypothesis (MH), on the nature of mass m is presented. Accordingly, the mass m0 of submicroparticle (SMP), is given by the kinetic energy accumulated inside the SMP, by the vortices/vibrations of groups of ether (ETH) cells, constituting the submicroparticles (SSMP). These SSMPs will also create the inertial force (FI) of the SMP, due to the opposition manifested by ETH, toward any accelerated movement of SMP. A new explanation of mass m increase, with V is proposed, admitting the existence of ether in the form of our model, HM16. The entrainment of the surrounding ETH of SMP, takes place, with speed VETH, which stores the EETH energy. The spatial variation of VETH around the SMP, was analysed using the method of potential motions, for a cylinder, moving in water-like fluid, or in ETH, resulting a spectrum of the lines of current ψ, indicating the size of VETH, rapidly decreasing with distance r. So resulted the kinetic energy EETH stored by the movement of the outer ETH, which provides the supplementary mass ms. The case of SMP which acquires velocity V, approaching c, was analysed. Then, a phase change (PC) will take place, through which the SMP, transforms into photons (PHs), when movements of the ETH from the outside including energy EETH is transferred into PH photons, having velocity c, representing ETH’s property.

A possibility is that in cosmic background, primordial photon lattice where emerges a way to mass conservation, a photon was disturbed to create a spin then lead to its neighbors consecutively avalanching -- CMB -- into this a small ripple, which inverse spin directions pointing to a world was made of matter or antimatter whichever is parity violation; now cosmos was like an expanding hole -- an isotropic gravity field -- in photon lattice that influenced on everything, so inertia will be partly clarified.
A Cognitive Analysis of Si Mohand’s Translated Poetry L’Amitié Bafouée
Authors: MECHAT Kahina , YASSINE Souryana
Published: February 2021

Kabyle oral poetry is the spirit of Kabyle literature. Si Mohand’s poetry was and still is the subject of many studies. The current research is Cognitive and analytical and aims to explain the English translated version of poem 16 taken from L’Amitié Bafouée, using schema theory, following Semino’s (2014) proposed approach to poetry analysis. Terminologies advanced by Schank and Abelson (1977), Schank’s Dynamic Memory (1982), and Cook’s Schema Refreshment (1994), will be used in the analysis. The study’s significance is firstly shown through its corpus, i.e. previous works dealing with Si Mohand’s poetry mostly made use of either the French or Kabyle versions. And secondly, through the use of a combination of terminologies advanced by the previously mentioned scholars. The study aims to answer the following main question: what is the main scene projected by the poem? And the following sub-question: what is the impact of culturally translated metaphors on readers? Results show that nine scripts need to be activated to form the betrayal Scene. Moreover, the use of literal translation in cultural metaphors specifically, led to difficulties in activating appropriate scripts in order to allow understanding to take place. In fact, understanding is determined by the reader’s background knowledge. The current analysis can also be used in translation assessment, detecting cultural misunderstandings, comparative studies of poetry, and can even be introduced to teaching.

Indonesia plans to build solar PV plants to reach 6500 MW capacity by 2025. One of the solar PV applications is systems with battery storage systems. In this system, the battery is an important component of the solar PV system as it stores the energy for use when the sun is unavailable. This article reviews the status of batteries in Indonesia to support the proliferation of solar PV applications. The objective is to compile a battery database for solar PV applications. The database provides insight into technology and the availability of batteries. The database consists of 361 batteries of various technologies such as FLA, VRLA, VRLA gel, VRLA AGM, and Lithium-ion. The most widely available is the VRLA gel. In terms of voltage, batteries are available at 2 to 12 volts and with capacity from 1 to 3000 Ah. The availability of batteries shows that this field is ready to support the development of solar PV with energy storage although the field of battery recycling or its waste management requires more attention.

Authors: Dorocki Sławomir , Kula Alina
Published: February 2021

Celem artykułu jest przedstawienie przestrzennego zróżnicowania rozwoju nanotechnologii w Europie. Analizę rozwoju nanotechnologii przeprowadzono na poziomie krajowym, wykorzystując dane obrazujące liczbę patentów nanotechnologicznych, liczbę i strukturę firm nanotechnologicznych, liczbę konferencji o tematyce nanotechnologicznej oraz liczbę publikacji nanotechnologicznych. W artykule oparto się na analizie statystycznej danych liczbowych pozyskanych w wyniku kwerend przeprowadzonych na portalach internetowych: Cientifica Plc, Biotechgate, Nanoforum, Nanowerk, Nanotechnology Now, Web of Science i PubMed oraz danych publikowanych przez OECD i Eurostat. Nanotechnologia zaliczana jest do jednego z głównych działów aktywności sektora nauki, technologii i innowacji i jawi się współcześnie jako technologia przyszłości. Na całym świecie panuje przekonanie o rewolucyjnym potencjale nanotechnologii. W latach 2001–2014 ponad 60 krajów podjęło finansowanie inicjatyw z dziedziny nanotechnologii. Są to zarówno rozwinięte przemysłowo kraje Europy Zachodniej, Japonia, Kanada czy Australia, jak i wschodzące rynki Rosji, Chin, Brazylii i Indii, jak i kraje rozwijające się, np. Nepal i Pakistan. Według liczby zgłoszeń patentowych z nanotechnologii na świecie dominują kraje rozwinięte: USA, Japonia i Niemcy. W latach 90. XX wieku nastąpił wyraźny wzrost liczby patentów nanotechnologicznych. W przestrzeni europejskiej pod względem liczby patentów nanotechnologicznych dominują Niemcy oraz Francja i Wielka Brytania. Jeśli rozpatrujemy liczbę ogółu instytucji nanotechnologicznych, to wyróżniają się w Europie dwa kraje: Niemcy i Wielka Brytania. W Niemczech przeważają instytucje działające w relacji B2B, podczas gdy w Wielkiej Brytanii są to instytucje badawcze non profit. Analizując liczbę patentów i firm nanotechnologicznych oraz liczbę publikacji i konferencji, należy stwierdzić, że rozwój nanotechnologii w Europie jest bardzo zróżnicowany. Sektor ten rozwija się głównie w krajach rozwiniętych gospodarczo. Europejskim liderem nanotechnologicznym są Niemcy. Innymi państwami z wysokim poziomem rozwoju nanotechnologii są: Wielka Brytania, Francja, Szwajcaria, Szwecja, Holandia i Hiszpania. Rozwój nanotechnologii stymulowany jest głównie przez publiczne instytucje badawcze, jednakże komercjalizacja badań następuje dzięki udziałowi firm prywatnych.

Industrialization is a process which is based on precise and quantitative measurements andcontains different basic changes in the economic structure of a country or region. The structural characteristicsand spatial distribution of the industrial enterprises established during the industrialization processwhich is one of the most important elements of the socio-economic transformation in Turkey withina historical process has been the object of this study. The aim of the study was to establish the positionsand significance of one thousand (1000) large industrial companies in the industry of Turkey by usingthe framework of criteria based on sales from production which have been maintained by the IstanbulChamber of Industry on a regular basis. The workplace and number of employees of the companies ona province basis, sector based division, realized exports and sales from product output, corporate entities,structures, spatial distribution and other characteristics were taken into consideration in the study.Although the thousand large scale companies in Turkey based on production output sales comprised only0.40% of the enterprises active in the industrial sector in 2012, they comprised 12% of the labor force,59.6% of product output sales and 65.2% of all exports. On a regional basis, 54% of these companiesare located in the Marmara region, 13.2% are located in Central Anatolia and 12.4% are located in theAegean region; on a province basis, 63.4% are located in Istanbul, Izmir, Bursa, Kocaeli and Ankara.A sector based division of the companies shows that 21.4% are involved in food, beverage and tobaccoprocessing, 19.6% are involved in the industry of metal goods, machinery, automotive industry, electricaltools and equipment and 16.1% deal with textiles, ready-to-wear, leather and the manufacturingof shoes. In terms of labor force numbers, the figures vary as 18.9%, 27.4% and 17.9% respectively.
Ocena zmian struktury pracujących w unijnych regionach szczebla NUTS 2 z wykorzystaniem miary Braya i Curtisa
Authors: Markowska Małgorzata
Published: February 2021

Celem artykułu jest ocena zmian struktury pracujących, zaobserwowanych w europejskiej przestrzeni regionalnej szczebla NUTS 2. Struktura pracujących zostanie ujęta w układzie trzech sektorów gospodarki, czyli rolnictwa, przemysłu i usług. Zakres czasowy prowadzonych badań dotyczy dwóch zazębiających się okresów, lat 2000–2008 i 2008–2012, co wynika ze sposobu prezentacji danych w bazach Eurostatu (zmiana podejścia do nomenklatury Europejskiej Klasyfikacji Działalności Gospodarczej NACE z 1997 roku, która w 2008 roku została uaktualniona). Przyczyny zmian to głównie pojawienie się nowych dziedzin działalności, zwłaszcza tych związanych z usługami i technologiami informacyjnymi oraz komunikacyjnymi. W nowym układzie NACE różnią się głównie dane na temat działalności firm, a z tego powodu także dane dotyczące rynku pracy, w tym – przykładowo – zmieniły się definicje pracujących w przemysłach wysokiej technologii i usługach opartych na wiedzy, co spowodowało utratę porównywalności. Jako metodę badawczą zastosowano w pracy miarę zróżnicowania struktur, co umożliwi identyfikację intensywności przeobrażeń na rynku pracy w czasie i przestrzeni.
Zróżnicowanie i dynamika rozwoju regionów Europy Środkowo-Wschodniej w okresie prosperity i kryzysu
Authors: Smętkowski Maciej
Published: February 2021

Celem artykułu jest ukazanie skali zróżnicowań regionalnych oraz dynamiki rozwoju regionów krajów Europy Środkowo-Wschodniej (EŚW). W artykule podjęto próbę odpowiedzi na następujące pytania badawcze: a) czy rozwój regionalny krajów EŚW jest zgodny z hipotezą J.G. Williamsona (1965) dotyczącą zależności między poziomem dochodu krajowego a skalą regionalnych zróżnicowań, b) jakie są główne przyczyny zmiany skali zróżnicowań regionalnych w ujęciu przestrzennym oraz c) jak kryzys gospodarczy wpłynął na dynamikę rozwoju regionów. Badania empiryczne pokazały spadek tempa dywergencji regionalnej wraz ze wzrostem poziomu dochodów w poszczególnych krajach. Następowało to w warunkach dość wyraźnej petryfikacji regionalnej struktury gospodarczej – zwłaszcza po wyłączeniu z analiz regionów stołecznych – co może wskazywać na zbilansowanie procesów rozprzestrzeniania i wymywania w warunkach prosperity gospodarczej – zwłaszcza w latach 2004–2008. Natomiast pierwsza faza kryzysu gospodarczego miała w wymiarze przestrzennym dość mozaikowy charakter, ale przy zauważalnej lepszej adaptacyjności większości regionów stołecznych.

Authors: Woźniak Ewa
Published: February 2021

Celem artykułu jest przedstawienie efektów funkcjonowania specjalnych stref ekonomicznych (SSE) w Federacji Rosyjskiej. Omówione zostały cele powołania stref, uwarunkowania prawne oraz społeczno-gospodarcze ich rozwoju.W szczegółowy sposób opisano typy stref występujących w Rosji. Są to strefy: przemysłowo-produkcyjne, techniczno-wdrożeniowe, turystyczno-rekreacyjne i portowe. Scharakteryzowano je pod względem powierzchni, nakładów inwestycyjnych, liczby rezydentów oraz liczby utworzonych miejsc pracy. Wnioski zostały przedstawione w oparciu o analizę danych statystycznych pochodzących ze strony internetowej Ministerstwa Rozwoju Gospodarczego Rosji i raportu o rezultatach funkcjonowania specjalnych stref ekonomicznych. Utworzenie stref w Rosji miało wpłynąć na wzrost eksportu, rozwój technologii i aktywizację gospodarczą regionu. Ważnym celem ich powołania było zwiększenie zatrudnienia i szkolenie wysoko wykwalifikowanych pracowników. W Rosji działalność prowadzą 343 firmy, które w 2013 roku zainwestowały ponad 100 898 mln rubli (1654,7 mln euro). SSE zostały utworzone w 2005 roku. Inwestorzy mogą korzystać z preferencyjnych warunków, m.in. z ulg podatkowych. Wysokość płaconego podatku zależy od typu strefy. Dla stref przemysłowo-produkcyjnych i portowych wynosi ona 2%, natomiast dla techniczno--wdrożeniowych 0% (przez okres 5 lat) i turystyczno-rekreacyjnych 0% (przez 10 lat).
Zmiany struktury sektora usług w Polsce w latach 1995–2012
Authors: Dominiak Joanna
Published: February 2021

Obecny poziom rozwoju sektora usług w Polsce jest przede wszystkim konsekwencją uwarunkowań politycznych i gospodarczych, jakie istniały w państwie w ostatnich dziesięcioleciach. W okresie realnego socjalizmu polityka społeczno-gospodarcza ukierunkowana była na rozwój przemysłu. Udział zatrudnionych w usługach w latach osiemdziesiątych był w porównaniu z rozwiniętymi krajami europejskimi znacznie niższy. Dopiero zmiany polityczne, społeczne i gospodarcze zapoczątkowane w Polsce w 1989 roku stworzyły podstawy do bardziej dynamicznego rozwoju tego sektora. Lata dziewięćdziesiąte charakteryzowały się szybkim wzrostem zatrudnienia w działalności usługowej. W latach 1990–2011 udział pracujących w tym sektorze zwiększył się z 37% do 55%. Wzrastał także udział sektora w wytwarzaniu wartości dodanej brutto. Rozwój sektora usług był zróżnicowany regionalnie – wysoką dynamiką cechowały się województwa z dużymi aglomeracjami miejskimi: mazowieckie, wielkopolskie, małopolskie. Celem artykułu jest prezentacja przemian zachodzących w sektorze usług w Polsce na tle innych państw Europy, a także charakterystyka zróżnicowania przestrzennego tego procesu w Polsce w ujęciu regionalnym. Analiza zmian strukturalnych zostanie przeprowadzona w oparciu o Polską Klasyfikację Działalności 2004 i 2007, na podstawie danych publikowanych przez Główny Urząd Statystyczny. Dynamicznemu rozwojowi usług, jaki następuje w Polsce od początku lat dziewięćdziesiątych, towarzyszą przemiany związane ze strukturą sektora usług. Zmiany w strukturze sektora usług polegają na zmianach udziału poszczególnych rodzajów usług w sektorze trzecim, najczęściej analizowanych w oparciu o miernik zatrudnienia i udział w tworzeniu WDB. Analiza zachodzących zmian prowadzi do wniosku, że coraz większego znaczenia w sektorze usług nabierają usługi wyspecjalizowane, wymagające zatrudnienia pracowników o wysokich kwalifikacjach zawodowych, wśród nich usługi o wysokim nasyceniu wiedzą, oraz grupa usług dla producentów i dla biznesu. Nabierają one dodatkowo jeszcze większego znaczenia w związku z rozwojem gospodarki opartej na wiedzy.
Zagadnienie złożoności w problematyce badawczej przemysłu
Authors: Mrozińska Agnieszka
Published: February 2021

Współczesna ekonomia znajduje się obecnie w bardzo ciekawym momencie, gdyż wyjaśnianie zjawisk zachodzących w gospodarce powoduje, że nauka ta staje się coraz bardziej zróżnicowana. Wypowiedzi, zarówno na temat kondycji ekonomii, jak i stanu metodologii ekonomii, skłaniają do refleksji na temat wiarygodności dotychczas stosowanych założeń, a także umiejscowienia ekonomii w obszarze nauk społecznych. Wskutek zwiększającej się liczby dostępnych instrumentów analitycznych poszerza się obszar objęty analizami ekonomicznymi. Badania gospodarki, w tym także przemysłu, wymagają obecnie uwzględnienia takiej kategorii, jak złożoność, najprościej definiowana jako skomplikowanie relacji pomiędzy elementami wyodrębnionego systemu. Złożoność pozwala na analizowanie zagadnień związanych z przemysłem jako odzwierciedlenia zachowań skomplikowanego systemu adaptacyjnego i wprowadzanie nowych problemów badawczych. Celem opracowania jest zwrócenie uwagi na nowe możliwości badawcze w problematyce przemysłu, jakie kreowane są przez koncepcję złożoności.
