Myocardial infarction (MI) is a challenging clinical and public health problem among older adults in the United States, and elderly patients often have an atypical clinical picture. There is gender difference in occurrence of symptoms, women reported more nausea and shortness of breath than men. The absence of typical clinical signs hinders the management of coronary heart disease. The study aims to assess prevalent risk factors and warning signs & symptoms of MI patients and to find out difference in presentation of warning signs & symptoms of MI as per their age and gender.A descriptive research design that involved total enumerative sampling technique to collect data from the 150 MI patients at Sher-i-Kashmir Institute of Medical Sciences, Kashmir, using a “self-structured interview schedule”. Results: The findings revealed that most of the study subjects were males i.e. (72.7%0 and majority were less than 60 years of age i.e. 55.3% .There was a significant age difference in symptom presentation for sudden pain in the chest(p=0.041), sudden discomfort in the chest(p=0.041)sudden tightness in the chest(p=0.039), sudden pressure in the chest(p=0.040) palpitation(p=0.041), chest pain radiating to jaw ( p=0.045 ), chest pain radiating to neck (p=0.05 ), epigastric pain (p=0.041), nausea,(p=0.041), vomiting (p=0.039), belching (p=0.040) , indigestion, (p=0.046 ), shortness of breath( p=0.040 ), faint (syncope),(p=0.049), sudden sleep disturbances(p=0.048), hot or cold sensations (p=0.047 ) .In gender, there was a significant gender difference with males showing for sudden pain in the chest(p=0.047), sudden discomfort in the chest (p=0.047)sudden tightness in the chest(p=0.047), and sudden pressure in the chest (p=0.047) vomiting (p=0.047). Conclusion: Majority of the patients were smokers, physically inactive. Warning signs and symptoms of MI are influenced by age and gender. Less than 60 years patients have higher odds for typical warning signs & symptoms and more than 60 years have higher odds for atypical warning signs and symptoms of MI. Male patients have higher odds for typical signs and female patients have higher odds for atypical warning signs and symptoms of MI.

Engels' philosophy of openness and nonlinear system in dialectics of Nature
Authors: Han Binyu
Published: October 2022

Engels' natural dialectics thought is the model of combining philosophy with natural science and is an important part of the Marxist ideological system. There is a close connection between the dialectics of nature and contemporary systems science. The former provides ideological support, philosophical basis, and theoretical origin for the latter, and points out the direction for the development of contemporary systems science. The law of the dynamic development of material forms revealed by dialectics of nature reveals the complex objective things and the objective world, as well as the nonlinearity, complexity, and diversity of matter. The analysis and study of system complexity, openness, and nonlinearity, has important theoretical significance for the enrichment and development of materialist dialectics and provides a new perspective of research analysis and demonstration for materialist dialectics

Authors: CHAUDHARY SANDHYA S , SINGH VIRENDRA KUMAR , MANAT TANVI D
Published: October 2022

Present study was conducted on 12 dry Surti buffaloes to assess the effect of heat stress amelioration during dry period on their biological responses and milk production in subsequent lactation. Buffaloes were divided into control (n=6) and treatment (n=6) groups. Treatment buffaloes were housed only during their dry period in shed having wall-mounted fans, roof whitewashed with microfine lime powder and open paddock covered with 75% green net. At -8, -3, +1 and +3 weeks of calving, blood collection and recording of observations (physiological, skin thermography and BCS) were done. Milk composition and daily milk yield were recorded at every 2 weeks up to 11 weeks of lactation, respectively. Shed modification was successful in lowereing air temperature and THI indicating thermal comfort for treatment buffaloes as also revealed by lower temperatures of rectum, tympanic membrane, surface like forehead, eye, udder, coronet and lower respiration rate. Treatment group maintained significantly higher BCS, glucose, total protein, GSH, TAS, in vitro lymphocyte proliferation, neutrophil phagocytic activity and lower levels of urea, creatinine, NEFA, BHBA, SOD, MDA, cortisol, TNF-α, IL-1β, IL-6 and HSP70. These results are indicative of minimum negative energy balance, stress and higher immune response. Milk yield and fat were higher in treatment group. Providing thermal comfort to buffaloes in dry period helped in abating the negative effects of heat stress not only during dry period but also during subsequent lactation along with improved milk yield.

Authors: RATWAN POONAM , CHAKRAVARTY A K , KUMAR MANOJ
Published: October 2022

Estimation of economic values is essential to decide the monetary importance of traits to be incorporated in breeding programs. The present study was conducted to estimate the relative economic value of first lactation traits, viz. 305-day milk yield (305DMY), average daily milk yield (ADMY), calving to first insemination interval (CFI), days open (DO), pregnancy rate (PR) and longevity (LNG) in Sahiwal cattle. Data spanning over duration of 29 years pertaining to production, reproduction and longevity of Sahiwal cattle kept at ICAR-NDRI herd were utilized. Averages of first lactation traits, viz. 305DMY, ADMY, CFI, DO, PR and LNG were obtained as 1822.59 kg, 6.62 kg/day, 85.56 days, 150.48 days, 38.00% and 2711.95 days, respectively with lactation length of 303.02 days in Sahiwal cattle. Expenses involved for different groups of animals for five years (2012-2016) were considered for appraising relative economic values of above-mentioned performance traits. Major expenses considered were per day cost of feeding, treatment, labour and artificial insemination for each animal. Cost of production of one kg milk was calculated as ` 23.68 which was the economic value of 305DMY and ADMY. The per unit expenses for traits CFI, DO, PR and LNG were ` 156.79, 156.79, 86.65, and 141.21, respectively in Sahiwal cattle. Relative economic values were estimated as 1, 1, -6.62, -6.62, 3.66 and 5.96 for 305DMY, ADMY, CFI, DO, PR and LNG, respectively. Relative economic values estimated in the present study will be helpful for constructing selection indices for genetic progress of Sahiwal cattle.

Published: October 2022

India has the privilege of having excellent dog populations, but efforts to recognize them as distinct breeds are far and wide. The present study was designed to undertake the phenotypic characterization of Gaddi dogs, in Himalayan region of the state of Himachal Pradesh, India. The approach used was to gather as much information available on Gaddi dogs from communities involved in their traditional rearing. Though, many anecdotal evidence about its origin exists, the most plausible relates it to the development of this distinct breed by Gaddi shepherds during migration in Himalayan ranges. The Gaddi dogs are predominately black with occasional white marking on the feet, tail, or trunk region. One of their main attributes is their massive, arched neck that protects them from predators. These dogs have harmonious build, medium stature, moderately long, robust muscular body. In bitches, age at first estrus ranged from 12-18 months with main breeding season from September to November. The number of whelping in a lifetime was reported to be 8-12 with a litter size of 4-8 pups. Shepherds usually do not follow a strict vaccination or deworming schedule of the dogs and housing is also not provided. The dog is primarily developed and used for the herding of sheep and goats by shepherds of the Gaddi tribe. These shepherds must be rewarded and encouraged to maintain the purity of the breed. The present study paved the way for recognition of the Gaddi dog and highlighted the headway options for its conservation and propagation.

A Poetic Approach to Teaching English: Personal Account
Authors: Almaktary Hussein
Published: October 2022

This paper accounts for teaching English vocabulary through rhythmic patterns, including short verses. It is a personal account of poetry as a valuable tool for both learners and teachers. Adopting a qualitative research design, the study set out to refute the longstanding view that poetry is hard to learn and teach. It derives illustrations from the researcher’s personal experience, who is basically, besides composing poems, a teacher of  English as a foreign language and curriculum designer. Ten short poems were used to clarify that poetry, which has taken a backseat in English language teaching for years, can now be a vivid teaching approach that numerous teachers and ELT experts advocate. On the main, verse-based teaching is motivational, amusing, and scaffolding. Based on the discussion, the study recommends using simple and easy-to-understand verses to enhance vocabulary learning, partially because rhyming words are more memorable and useable in conversational English. The study concludes with some suggestions to strengthen the evidence of the viability of poetry in TESOL programs.

Published: October 2022

The study examined the impact of monetary policy decisions in stimulating the assets of deposit money banks in Nigeria 2000-2020. While the specific objectives are to: Measure the impact of   interest rate spread on assets of deposit money banks in Nigeria. Determine the impact of exchange rate on assets of deposit money banks in Nigeria. Investigate the impact of inflation rate on assets of deposit money banks in Nigeria. The model used in this study is Auto regressive distributed lag as a form of multiple regression models. It is a special type of regression called auto regressive distributed lag. Result revealed that Interest rate had a negative and non-significant impact on assets of deposit money banks in Nigeria, Exchange rate had a positive and significant impact on assets of deposit money banks in Nigeria, Inflation rate had a negative and non-significant impact on assets of deposit money banks in Nigeria,. The implication of findings revealed that if the government fails in their monetary policy decisions, it will go a long way to affect deposit money banks and also economy. The study concluded that monetary policy decisions play serious significant effects on the assets of deposit money banks in Nigeria. It was recommended that government should create reasonable credit to private sector and therefore regulates the interest rate to be charged. Exchange rate has a significant effect on Insurance profitability in Nigeria. This study recommend that public enlightenment campaigns should be done by government directing people about the availability of money kept for agricultural loans and various credits so as to control black market in exchange rate. It was recommended that effective policies such as policies that will encourage manufacturers to have access to bank credits without democratic bottleneck will go a long way to provide efficiency in the system and hence improves or control inflation; however, gradual control of inflation through mopping up excess liquidity will be done by the monetary authorities to enhance the growth of deposit money bank assets.

Authors: DATTA TANMAY , DAS DEBASHIS
Published: October 2022

This study was conducted in five wetlands of North Bengal to find out impact of anthropogenic activities in diversity of fish species. Total 101 fish species were documented in those wetlands. Maximum species (93) were recorded from Gajoldoba wetland, whereas Nimai beel recorded only 33 species. Results indicate that anthropogenic activities (other than fishing) affected ichthyofauna diversity adversely. Human interferences altered electrical conductivity, dissolved oxygen, BOD, free carbon dioxide, phosphate and nitrate level significantly. Also, human interferences significantly affected emergent vegetation covered shore area and percentage of floating vegetation. All those physio-chemical and vegetative changes possibly affected the zooplankton diversity negatively dwindling the base of the food chain and in turn, affected fish diversity. Immediate and proper action should be taken to save this biodiversity and the wetland of this region as a whole.

Authors: Wasilewicz-Pszczółkowska Monika , Senetra Adam , Szczepańska Agnieszka
Published: October 2022

Intensified anthropogenic pressures contribute to land degradation and devastation around the globe. Land degradation leads to a temporary or a permanent decline in the productive capacity of land. Degraded agricultural land is often converted to non-agricultural uses, as the result areas with natural land cover (arable land, meadows, pastures) are transformed into anthropogenic landscapes. The objective of this study was to analyze the changes in the area of degraded land in the Warmińsko-Mazurskie Voivodship based on the scope of implemented land reclamation measures. The area of land converted for non-agricultural purposes, the revenues generated from conversion fees and their distribution were also evaluated. The analyzed data covered the period of 2007–2012.

Authors: Burda Andrzej , Pancerz Krzysztof
Published: October 2022

Pattern recognition of bankrupt or non-bankrupt enterprises may not only extend or confirm the knowledge in economics, but also deliver to experts, from the standpoint of the decision support, a view of the economic and financial situation of the audited enterprise. Therefore, it may be an effective tool for early warning of the bankruptcy risk of the enterprise. Such a tool is especially important for small and medium enterprises (SMEs) in the underdeveloped regions. The research described in the paper is intended for generation and visualization of the state of SMEs in the Podkarpacie region on the basis of information included in financial reports. A self-organizing map (SOM), often called the Kohonen net, has been used in the unsupervised modelling mode. Results of research show a high potential of the method to the stated objectives and the simplicity of the representation of knowledge transferred to entrepreneurs and financial analysts.
Rozwój zasobów kapitału ludzkiego szansą dla polskich regionów
Authors: Łuszczyk Marcin
Published: October 2022

Spowolnienie gospodarcze, którego jesteśmy świadkami, skłania do poszukiwania nowych czynników wzrostu, wśród których na szczególną uwagę zasługuje kapitał intelektualny. Szerokie wykorzystanie zasobów kapitału intelektualnego w procesie tworzenia dochodu pozwala uzupełnić niedobory kapitału pochodzenia antropogenicznego i coraz bardziej ograniczone zasoby naturalne. Zdaniem autora szansą na pobudzenie rozwoju społeczno-gospodarczego polskich regionów są przemyślane inwestycje mające na celu powiększenie zasobów kapitału intelektualnego. Skutecznym sposobem realizacji tego zadania może być wspieranie nauki i szkolnictwa wyższego w regionie. Aby jednak podjęte działania w zakresie edukacji były skuteczne i trwałe niezbędne jest ich uzupełnienie. Mogą to być programy wspierające rodziny, ale takie, które oferują wymierne korzyści również rodzicom z dwójką dzieci. Aktywność samorządów w zakresie rozwoju edukacji i polityki społecznej powinna przynieść dodatkowe korzyści w postaci efektów synergicznych.
Human Capital in the Visegrad Group NUTS 2 Regions. Convergence or Divergence?
Authors: Dańska-Borsiak Barbara
Published: October 2022

An important objective of the European Union cohesion policy is to remove economic disparities between the various regions. One of the factors capable of stimulating or slowing the development process is human capital. The specialist literature provides many alternative human capital measurement concepts. In quantitative research, various composite measures are most commonly used. Such a measure was also developed in this study. The main aims of the study were: to construct a human capital measure for the Visegrad Group countries’ NUTS 2 regions, to examine whether spatial relationships occur in the distribution of human capital in the studied area and to analyze regional convergence in terms of human capital levels in the years 2001–2015. The study applied the marginal vertical beta-convergence concept, which enables the determination of individual contributions of particular regions to the general convergence process characterizing all the studied objects. Dynamic panel data models were used to study convergence, and Moran’s global and local statistics were used for inference about spatial dependencies. As expected, no spatial autocorrelation was found. In contrast, the hypothesis of convergence was confirmed and regions that contribute to the weakening of its pace were identified.
Sektory oparte na wiedzy a aktywność patentowa — próba określenia relacji w ujęciu statystycznym
Authors: Szajt Marek
Published: October 2022

Innowacyjność gospodarki traktowana jest jako klucz do jej rozwoju. Coraz częściej spotyka się opracowania, których autorzy podejmują próbę określenia głównych determinant tejże innowacyjności. W niniejszym artykule, obok najczęściej wykorzystywanych w badaniach nad innowacyjnością czynników jak: personel B+R, wydatki brutto na działalność B+R (GERD), czy częściej ostatnio analizowane zasoby ludzkie dla nauki i techniki (HRST) wykorzystano również potencjał sektorów opartych na wiedzy (KIS). Potencjał ten, mierzony zatrudnieniem w tych sektorach jest silnie powiązany — co udowodniono w badaniach — z aktywnością patentową będącą miernikiem innowacyjności. Celem badań było określenie relacji KIS — aktywność patentowa na tle innych czynników. Badanie obejmowało dane na poziomie NUTS 1 i NUTS 2. Wykorzystano dane dla 28 państw Unii Europejskiej oraz po dezagregacji 265 regionów z lat 1999–2013. Dane — pochodzące z Eurostatu zostały poddane analizie statystycznej z wykorzystaniem miar korelacji, koncentracji oraz lokalizacji przestrzennej. Jako miarę aktywności innowacyjnej wykorzystano aktywność patentową. Wyniki potwierdziły kluczowe znaczenie zasobów ludzkich w sektorach opartych na wiedzy dla wzrostu aktywności patentowej w sektorze wysokiej techniki.
Zmiany poziomu bezrobocia długookresowego w Polsce w ujęciu regionalnym
Authors: Zieliński Mariusz
Published: October 2022

Celem artykułu jest analiza zmian poziomu i struktury bezrobocia długookresowego w Polsce w ujęciu regionalnym w latach 2005–2015. Struktura bezrobocia według czasu pozostawania bez pracy jest o tyle istotna, że w warunkach zmniejszającej się (ze względów demograficznych) podaży pracy, rosnący udział bezrobocia długookresowego utrudnia przesunięcie bezrobotnych do zasobów pracujących, co może stanowić barierę rozwojową dla gospodarki. Hipotezą postawioną w artykule jest twierdzenie, że zmniejszeniu poziomu bezrobocia towarzyszy wzrost udziału bezrobocia długookresowego i pogorszenie jego struktury, w postaci zwiększenia udziału osób o niskim wykształceniu i w wieku niemobilnym. W artykule wykorzystano statystykę opisową w oparciu o metodę indeksową, a także analizę korelacji między wzrostem PKB, poziomem bezrobocia ogółem i poziomem bezrobocia długookresowego. Do analizy wykorzystano dane publikowane przez GUS w Rocznikach Statystycznych Województw. Wyniki badań pozwoliły na pozytywną weryfikację hipotezy o wzroście udziału bezrobocia długookresowego i pogorszenia jego struktury w postaci wzrostu udziału osób w wieku niemobilnym. Nie potwierdziła się część hipotezy o pogorszeniu struktury bezrobocia długookresowego w przekroju według wykształcenia.
Projekty hybrydowe — montaż partnerstwa publiczno-prywatnego i funduszy Unii Europejskiej w projektach rozwoju lokalnego i regionalnego
Authors: Szafran Joanna
Published: October 2022

Partnerstwo publiczno-prywatne (PPP) rozwija się w Polsce dynamicznie, w odpowiedzi na rosnące potrzeby inwestycyjne przede wszystkim samorządów lokalnych i regionalnych, które napotykają na ograniczenia know-how, budżetowe i związane z zapewnieniem wkładu własnego projektów współfinansowanych z budżetu UE. Dalszemu jego rozwojowi sprzyjają zmiany w regulacjach UE i krajowych na lata 2014–2020, promujące realizację projektów PPP współfinansowanych z funduszy, inicjatyw i instytucji europejskich, tzw. projektów hybrydowych (mieszanych). Celem publikacji jest ukazanie specyfiki takich projektów i ich znaczenia na rynku PPP, w kontekście szerszego ich stosowania w bieżącej perspektywie finansowania krajowych i regionalnych programów operacyjnych. Analiza źródeł prawa UE i krajowego oraz analiza ilościowa i strukturalna rynku PPP i projektów hybrydowych pozwoliła na przedstawienie modelowych rozwiązań oraz wskazanie zalet i barier realizacji takich projektów przez samorządy. Dzięki dofinansowaniu przede wszystkim z Europejskiego Funduszu Rozwoju Regionalnego i Funduszu Spójności hybrydy wyróżnia duża wartość umów zawieranych w sektorach IT, gospodarce odpadami, energetyce i rewitalizacji, które obok transportu i ochrony zdrowia są preferowanymi kierunkami wsparcia UE.

Published: October 2022

Article’s aim is the critical analysis of the literature and case study of the knowledge transfer issue into Opolskie Voivodship by foreign investment of the hi-tech sector. To illustrate such undertaken problem the role and a place of knowledge transfer and high technologies sector as the factor having an impact on development of the region was discussed. Enterprises — foreign investors — are the source of the knowledge for human capital of the region, and because of that for enterprises of the region. There also will be pointed the practical example from Opolskie Voivodship, at the base of knowledge transfer by hi-tech enterprise into Opolskie Voivodship. After such stated analysis it is possible to state that foreign investment of hi-tech sector and knowledge transfer to region being their consequence, constitute actual field of scientific interests. As the pro-innovative action it is simultaneously the field of the mutual cooperation of hi-tech sector and regional economy. Interactions of these subjects are important not only from the point of view of mutual benefits, such as knowledge transfer by the side of regional economy and economic benefits, including those connected to regional human capital, by the side of hi-tech sector. Thus foreign investment of that sector can be pointed as the source of innovation, know-how and knowledge transfer, but also as the engines of social and economic changes in the region.
The Development of Residential and Commercial Real Estate, and Economic Development in Polish Voivodships
Authors: Łaszek Jacek , Leszczyński Robert , Olszewski Krzysztof
Published: October 2022

The article presents the development of residential and commercial real estate in Poland and its 16 voivodships. This is closely linked to the economic development of the regions. The first part shows how the stock of this real estate grew on a national scale and how their values changed. The second part analyzes the change in the stock of residential and commercial real estate (office and commercial property) in particular voivodships. Dependencies are noted. The residential areas developed in a similar manner in different voivodships, with supply increasing with a delay of about two years after economic growth. This can be explained by the fact that when the economic situation of households improves, they want to improve their housing situation. On the other hand, the development of commercial space is accompanied by economic development with a one-year delay. Taking into account that the process of physical construction takes about 2 years, this implies the existence of a strong endogeneity between employment in the service or retail sectors and income growth. This endogeneity acts as feedback (revenue growth is an increase in surface area, which in turn generates income), so the cause and effect have slight time delays. The development of commercial real estate in individual voivodships intensified in different periods. This is probably connected with the inflow of foreign capital, which first came to Warsaw and the Warsaw agglomeration, then to large centers (Trójmiasto, Poznań) and only with some delay to other voivodships.

Authors: Bedrunka Karina
Published: October 2022

W świetle obecnych oraz prognozowanych problemów demograficznych istotne jest podejmowanie efektywnych działań na wielu poziomach zarządzania polityką regionalną i w wielu obszarach tej polityki. Skuteczne pozyskiwanie środków finansowych, w tym unijnych ukierunkowanych na procesy społeczne, może w realny sposób wpływać na niwelowanie skutków społecznych i gospodarczych wynikających z niekorzystnej sytuacji demograficznej np. starzejącego się społeczeństwa, czy też w odniesieniu do spodziewanych zmian na rynku pracy na co istotny wpływ ma zdrowie społeczeństwa. Celem badań jest wskazanie, czy i w jaki sposób są identyfikowane ex ante bariery wdrażania regionalnych programów zdrowotnych zapobiegania cukrzycy, nadwadze i otyłości oraz w zakresie wsparcia matki i dziecka. Celem praktycznym jest sformułowanie rekomendacji, w jaki sposób bariery usuwać, a także zaproponowanie rozwiązań, które pozwolą na efektywne wdrażanie programów i osiąganie wskazanych w nich efektów poprzez inicjatywy projektowe współfinansowane z Europejskiego Funduszu Społecznego (EFS). Realizowane i planowane inicjatywy projektowe dotyczące obszaru zdrowia, swoją bazę mają w regionalnych programach zdrowotnych wspieranych ze środków unijnych w perspektywie 2014–2020. Województwo opolskie ma w tym zakresie doświadczenia, jako jedne z pierwszych w kraju.
