Öğretimi Planlamada Örtük Programın Rolüne İlişkin Öğretmen Görüşlerinin İncelenmesi
Authors: YURTSEVEN Nihal
Published: April 2019

Öğretimi planlama, öğrencilere yeterli
performansı kazandırmak üzere öğretim sürecini etkili bir biçimde planlama, geliştirme,
değerlendirme ve yönetme sistematiğidir.
Öğrenme süreci gözden geçirildiğinde, öğrencilerin tek tip bir bilişsel
öğrenme deneyimi yerine, duyuşsal davranışlar, tutum, öğrenme stilleri gibi
değişkenlerden doğan farklılıklardan etkilenebileceği anlaşılmaktadır. Bu durum
öğretimi planlama işinin yalnızca resmi programlarla sınırlı kalmayıp, örtük programın da bu sürece
dâhil olabileceğini göstermektedir. Bu araştırmanın
amacı öğretimi planlama sürecinde örtük programın rolüne ilişkin öğretmen görüşlerinin
incelenmesidir. Araştırma fenomenoloji (olgubilim) deseniyle
gerçekleştirilmiştir. Araştırmanın katılımcılarını farklı deneyim, eğitim
kademesi ve okul türlerinden 128 öğretmen oluşturmaktadır. Araştırmada veri
toplama aracı olarak görüş formu ve odak grup görüşmesi kullanılmıştır.
Araştırma kapsamında toplanan veriler içerik analizi ile analiz edilmiştir.  Araştırmadan elde edilen bulgulardan ilki,
öğretmenlerin örtük programı, resmi programın tamamlayıcısı ve resmi programın
belirleyicisi olarak iki farklı boyutta algıladıklarını ortaya koymaktadır. Araştırmadan
elde edilen ikinci bulguya göre, öğretmenler, öğretimi planlama sürecinde örtük
programı kurumsal, öğretimsel ve öğrenmeye yönelik ihtiyaçlara cevap veren
önemli bir olgu olarak yorumlamaktadır. Araştırmanın bulgularından üçüncüsü
öğretmenlerin öğretim sürecinde örtük programın daha etkin olan program türü
olduğunu düşündüklerini ortaya koymaktadır. Öğrenme ortamının
şekillendirilmesinde önemli rolü olan öğretmenlerin, okulda arzu edilen bir
öğrenme iklimi yaratmada örtük programı da dâhil ederek planlama yapmaları,
okulun organizasyonunu da bu doğrultuda geliştirmeleri, öğrencilerin kalıcı ve
anlamlı öğrenmeler gerçekleştirmeleri açısından önemlidir.

Ewolucja społecznej odpowiedzialności biznesu w Polsce
Authors: Jastrzębska Ewa
Published: April 2019

The purpose of this article is to show the evolution of the idea of corporate social responsibility in Poland. It is based on a critical analysis of literature, web research and participatory observation. Both birth of the idea of corporate social responsibility and stages of evolution of the way it is understood were similar in Poland and in Western Europe. However, those processes in Poland were delayed and their scale was smaller. The importance of the concept of CSR is also not as rigid and tends to change. This is due to the fact that the concept itself is derived from practice, evolving in response to the needs of society and business. However, the essence of responsibility remains constant and up-to-date.

Authors: Iłowiecka Katarzyna
Published: April 2019

Contracting of health care benefits is a very important tool that allows a payer to create desired structure, considering the needs notified by the patients, the cost-effectiveness and the quality of the benefits. Contracting is aimed at attaining a number of important tasks such as the implementation of the existing rules of access to health care and the development of supply and demand in a way that facilitates the implementation of the adopted health policy. Contracting of health care benefits is thus an important tool enabling to introduce the regulated market and regulated competition. Therefore, a correct model for contracting of benefits is essential for correct exchanges of the limited (and specific) resources on the healthcare market. The purpose of this article is to assess the contracting of health care benefits by the National Health Fund. The following areas impacting on contracting of benefits were analysed: sources of financing, benefits purchase planning, valuation of benefits and the procedures for the award of contracts. A SWOT analysis was used to perform the analysis. At present the contracting of health care benefits in Poland is regulated by the Act of 27 August 2004 on health care benefits financed from public funds (consolidated text: Journal of Laws 2015, item 581, as amended). The article describes the legal situation on 31 March 2016. The conclusions from the analysis confirm the need for change, in particular by improving the cost efficiency and the implementation of activities promoting comprehensive care of a patient.

Post-war anti-social evolution of housing policy becomes an important factor in the post-2008 deepening structural crisis of capitalism and in the end of the market paradigm of economic growth. This speaks for the analysis of social housing policy as a basis for re-evaluation of the paradigm of civilizational development towards better realization of the concept of sustainable development. Shared overreaching goals of sustainable development are best shown through the concept of infrastructure inhabited settlement. In this approach lie methodological possibilities of filling sustainable development with commonly understood social content.

Special Relationship Between the United Kingdom and the United States of America in the Light of Brexit and Donald Trump's Victory in the Presidential Election
Authors: Danel Łukasz
Published: April 2019

This article is devoted to the "special relationship" between the United Kingdom and the United States: a strategic partnership that has united these two countries for good after WWII, even though in many respects it has lasted since the first half of the 19th century. The author starts with presenting the historic outline of the "special relationship" with an emphasis on the characteristics of mutual ties and dependencies. The author also analyses the political circumstances in which tightening or loosening of the British and American relations took place. In the final part of the article, the author refers to the most recent political events, which in 2016 took place in Great Britain and in the United Sates. In this manner, the author is trying to answer the question on how the decision on leaving the European Union by Great Britain (the so-called Brexit) and the election of Donald Trump as the US president will influence the shape of the British and American alliance
Wykluczenie finansowe i integracja finansowa – aspekty terminologiczne
Authors: Czarnecka Maria
Published: April 2019

The aim of the article was to present the issue of financial exclusion and define sensitive areas of this phenomenon. The factors that may be relevant for measuring the degree of financial exclusion were analysed. An attempt was also made to determine the difficulties in access to financial services in the context of practices applied by both the supply and demand sides. In addition, barriers to the use of services were analysed as were financial products in terms of practices used by supply and demand. The typology of financial exclusion presented in the article is an attempt to define the type and scope of the phenomenon. Bank exclusion, credit exclusion and exclusion from the savings system are financial exclusion indicators. Each of those types of exclusion affects the economic and social level. Financial exclusion, which is one of the symptoms of the imbalance between demand and supply, is understood here as total or partial access to financial services offered by the market. The article also attempts to analyse the causes of exclusion with the division into supply and demand factors. The typology of financial exclusion proposed in the article may be a contributing factor to the reverse phenomenon, which is financial inclusion.

Modern libraries and the challenges
Authors: Mazuritsky Alexander , Kuzichkina Galina
Published: April 2019

The authors discuss the main challenges for the libraries related to the libraries’ mission, their role and place in the modern society. The brief historical review of librarianship is given; the key factors of its transformation are revealed. The focus is made on the libraries – government authorities interaction and, in particular, on the so-called optimization of public libraries which primarily means the decreasing library network. The well-shaped state policy in librarianship is lacking today which impedes development of an upgraded unified concept. By examining the ratio of information and cultural &educational functions of the public libraries, the authors conclude on the need for some balance based on social demand, target and resource potential of each library. The transformation of the concept of the library profession and related problems of library education as the foundation for preservation and development of human resources in the library sphere, are also discussed. The libraries’ principal response to the challenges lies in the theoretical substantiation, testing in practice, mobility and relevance.

The elusive early medieval glass
Authors: Milavec Tina
Published: April 2019

In graves 322 and 310 of the early medieval Nin – Ždrijac cemetery three
glass vessels, two stemmed goblets and one bottle were found. They have
been interpreted as remains of Late Antique glass production, but a closer look brings further information. The best comparisons for the goblets come from the North Adriatic area while the bottle is most probably of early Islamic production. Interesting possibilities of interpretation arise with the graves being furnished with glass products
of such different origin at a time when local secondary glass production seems to have been absent.
Chapter 12a: Epidemiology by country – an overview
Authors: Erber Wilhelm , Schmitt Heinz-Josef , Janković Tamara Vuković
Published: April 2019

• TBE is a flavivirus infection of the central nervous system (CNS), transmitted by ticks and in some rare instances by ingestion of unpasteurized milk. • TBE is diagnosed in the forested belts of Northern Eurasia ranging from eastern France and Norway down to northern Italy through central and Eastern Europe, Russia, Kazakhstan, and China to the northern Japanese island of Hokkaido. • About 10,000 cases of TBE are reported annually. • The European Centers for Disease Control (E-CDC) have put TBE on their list of notifiable diseases; their case definition requires clinical symptoms of CNS infection plus microbiolog-ical confirmation of the infection, usually by detection of specific immunoglobulins, IgG and IgM. • Despite this, surveillance of the TBEV in both ticks and humans is incomplete. Reported incidences do not reflect actual risk since this fluctuates annually as a result of changes in exposure, vaccine uptake, intensity of case finding and reporting, and climate, just to men-tion the most relevant factors. • For largely unknown reasons (including human behavior, improved diagnostics, or climate change) TBEV appears to be spreading north, east, and even south to areas that were pre-viously believed to be free of the virus. • The country reports in Chapter 12b provide a current and official ‘state-of-the-art’ survey on TBE, with available information about the virus, vectors, modes of transmission, case reporting, vaccine and prevention efforts, burden of disease over time, age and gender distribution of cases, virus isolation data, and risk area distribution. • Chapter 12c provides a risk map for TBEV based on documented TBE cases, TBEV infection, as well as on the detection of TBEV in nature. This map does not reflect the incidence of the disease or the prevalence of the virus in a given area. As the intensity and complete-ness of epidemiological surveillance varies between different countries, the map presented here may not be entirely complete, and very likely TBEV infections and thus TBE may occur in additional (‘new’) areas.

Authors: Warlis Hasni
Published: April 2019

Mathematics is one of the branches of science which has the most connection with other branches of science which function to advance students' thinking scientifically and construct new knowledge acquired by students. So from that mathematics learning really needs to be studied at the elementary school level. But based on observations, researchers found student learning outcomes were still relatively low. The low student learning outcomes are caused by several things, such as; 1) the teacher only uses the lecture method and questions and answers only, 2) the lack of teacher knowledge about innovative learning strategies and 3) the teacher is only focused on the textbook without making a new breakthrough. To overcome this learning problem researchers used a demonstration learning model. The results of the study show an increase in learning outcomes per cycle, when viewed from the initial data, the classical average value is 56 with a moderate category. After carrying out the first cycle the average value became 64.6 moderate categories and in the second cycle increased to 91.6 very good categories. Based on the results of the study, researchers can conclude that by applying the demonstration method in Class I of the 018 Marsawa Public Primary School, Sentajo Raya District can improve students' mathematics learning outcomes.

Authors: Andreeva Victoria , Karanauskienė Diana
Published: April 2019

Background. The paper deals with the precompetitive emotional state of dancesport athletes before competition.
Research aim was to analyze pre-competition emotional state of dancesport athletes.
Methods. The pre-competition emotional state of dancesport athletes was established using methods of in-
depth interview and participant observation. The main reasons for different types of emotional states were identified,
and finally, recommendations for athletes and coaches how to overcome immoderate anxiety interfering with good
competition results were developed.
Results. Precompetitive emotional state before competition may be described as a complex multi-faceted
phenomenon which consists of different psychological categories such as: anxiety, arousal, stress, self-confidence,
concentration. The results of the interviews and participant observation showed that precompetitive emotional states
of the dancesport athletes were both positive and negative. Positive emotional state was shown by the majority of
participants. There were found six reasons of positive emotional state and five reasons of negative emotional state
as well.
Conclusion. To overcome the negative emotional state or reinforce positive emotional state before the
competitions it is suggested to listen to pleasant music, do breathing exercises or do the mental exercise. The choice
depends on the personal characteristics of athletes.

Published: April 2019

Actuality of the topic and scientific problem.Many researchers and practitioners have already begun to discuss the diversity of opinions regarding what constitutes an SC approach. Whilst there is a broad consistency in general opinion,there are also growing concerns regarding the apparent misinterpretation of the “ingredients” of SCL and what SCL actually looks like in practice. A student-centred classroom is not a place where students decide what they want to learn and what they want to do. It is a place where we consider the needs of the students, as group and as individuals, and encourage them to participate in the learning process all the time(Jones, 2007). It is noted that after the analysis of Bologna process documents and scientific literature, using a logical inductive method to purify the essential criteria, which makes it possible to assess the role of teacher to student oriented approach. The results revealed that the role of the teacher in order to ensure the quality of higher education is significant because the training (learning) paradigm shift opens up the possibility of the teacher to change the style of work, continuous improvement, however, and require a larger time-consuming.The purpose of the article analyzes the transition to student-oriented learning experiences and challenges. Methods:literature and document analysis and synthesis, analysis of legal documents, comparative, logical and inductive generalization methods.Results. The research describes the most frequent types of student-centred learning such as problem-based learning, project-led education, learning contracts, flexible learning, inquiry learning, just-in-time checking and personalized learning.Сonclusions. This research presents opinions of relevant authors on the contemporary student-centered learning and enables an insight into the practice of lecturers. It shows that SCL has got its place in European universities however several of its aspects should be developed further.

Clinical Particularities of Drug-Induced Agranulocytosis or Severe Neutropenia in Elderly Patients
Authors: Andrès Emmanuel , Cottet Mourot Rachel , Keller Olivier , Serraj Khalid , Vogel Thomas
Published: April 2019

Agranulocytosis is a life-threatening disorder in any age and also in the elderly
subjects who are receiving on the average a larger number of drugs than younger
subjects. This disorder frequently occurs as an adverse reaction to drugs, particularly
to antibiotics, antiplatelet agents, antithyroid drugs, neuroleptics or anti-epileptic agents
and nonsteroidal anti-inflammatory agents. Although patients experiencing drug-induced
agranulocytosis may initially be asymptomatic, the severity of the neutropenia usually
translates into the onset of severe sepsis that requires intravenous broad-spectrum
antibiotherapy. In this setting, hematopoietic growth factors have been shown to shorten
the duration of neutropenia. Thus with appropriate management, the mortality rate of
idiosyncratic drug-induced agranulocytosis is now of 5 to 10%. Today, drug-induced
agranulocytosis still remains a rare event with an annual incidence from 3 to 12 cases
per millions of people. However, given the increased life expectancy and subsequent
longer exposure to drugs, as well as the development of new agents, physicians should
be aware of this complication and its management.

Authors: Muhammad  , Suleiman  , Jatau  , Chiroma
Published: April 2019

Kaempferol is a polyphenolic compound and are widely distributed in plants. It is used in the treatment of different disease conditions. With the endemic resistant parasites against most antitrypanosomal agents and the toxicity associated with diminazene aceturate, the search for safer and more effective alternative therapy of trypanosomosis becomes paramount. In this study the effect of treatment with kaempferol and diminazene aceturate on Hematological parameters in mice with experimental Trypanosoma brucei brucei infection was evaluated. Thirty six adult swiss albino mice of either sex were randomly divided into six groups of six mice each. Mice in group I were untreated uninfected. Mice in group II were pre-treated with kaempferol (1 mg/kg) for 14 days. Mice in groups II to VI each were inoculated with blood containing Trypanosoma brucei brucei (106 trypanosomes/ml of blood/animal) intraperitoneally. Following establishment of the infection (four days post-inoculation), mice in group III were treated once with diminazene aceturate (3.5 mg/kg) I.P. Mice in group IV were treated with diminazene aceturate (3.5 mg/kg) once I.P, and then continued with kaempferol (1 mg/kg) for nine days.
Routine Herd Health Data as Cow-Based Risk Factors Associated with Lameness in Pasture-Based, Spring Calving Irish Dairy Cows
Authors: Somers Joris R. , Huxley Jon N. , Doherty Michael L. , O’Grady Luke E.
Published: April 2019

Herd-level risk factors related to the cow’s environment have been associated with lameness. Uncomfortable stall surface and inadequate depth of bedding as well as abrasive alley way surface are contributing factors to increased levels of lameness. Access to pasture has been found as having a beneficial effect on cows’ locomotion. However, dairy cattle managed under grazing conditions are exposed to a different set of risk factors for lameness, mainly associated with cow tracks. Cow-based risk factors for lameness are not as clearly defined as the herd level risk factors. The objective of the present study was to use routine herd health monitoring data to identify cow-based risk factors for lameness and utilise this information to indicate cows at risk of developing lameness in the first 150 days of lactation. Lameness data were gathered from 10 pasture-based dairy herds. A total of 1715 cows were monitored, of which 1675 cows were available for analysis. Associations between lameness status and potential cow-level risk factors were determined using multivariable logistic regression. Parity 3 and 4 + cows showed odd ratios (OR’s) for lameness of 3.92 and 8.60 respectively (95% confidence interval (CI) 2.46–6.24; 5.68–13.0). Maximum loss of Body condition score (BCS) after calving exhibits OR’s for lameness of 1.49 (95% CI 1.08–2.04) if cows lost 0.5 in BCS after calving and 2.26 (95% CI 1.30–3.95) for cows losing more than 0.5 BCS. Animals calving in BCS 3.25 and ≥ 3.5 had correlating OR’s of 0.54 (95% CI 0.34–0.87) and 0.33 (95% CI 0.16–0.65) for being lame compared to cows calving with BCS ≤ 2.75. Data gathered as part of herd health monitoring can be used in conjunction with lameness records to identify shortcomings in lameness management. Findings and recommendations on lameness management can be formulated from readily available information on cow-based risk factors for lameness.

Otosyphilis is one contributing cause of hearing loss in adult patients. There are limited studies on the treatment regimens of otosyphilis. Penicillin G sodium (PGS) plus additional medications, such as benzathine penicillin and probenecid, is an effective regimen. This study investigated the efficacy of PGS alone for the treatment of otosyphilis. We conducted a retrospective study and included all consecutive patients diagnosed with otosyphilis who received only PGS treatment. The study period was from 2009 to 2013. The PGS treatment regimen was PGS 4 mu intravenously every four hours (24 mu/day) for 14 days. Clinical and audiogram outcomes were evaluated one year after treatment. There were 34 otosyphilis patients that were treated with PGS. After one year of treatment, 18 patients (52.9%) had a clinical improvement and 11 patients (32.4%) had an audiogram improvement. In conclusion, PGS at 24 mu/day for two weeks provided an audiogram improvement one year after treatment in one-third of the patients.

To better understand the evolution of crack propagation in brittle rock mass, the particle velocity field evolution on both sides of secondary crack in rock-like materials (cement mortar specimens) with pre-existing parallel double flaws under uniaxial compression is analyzed based on the discrete element theory. By bringing in strain rate tensor, a new technique is proposed for quantifying the failure mechanism of cracks to distinguish the types and mechanical behaviors of secondary cracks between pre-existing parallel flaws. The research results show that the types and mechanical behaviors of secondary cracks are distinct at different axial loading stages and can be directly identified and captured through the presented approach. The relative motion trend between particles determines the types and mechanical behaviors of secondary cracks. Based on particles movement on both sides of secondary cracks between cracks, the velocity fields of particles can be divided into four types to further analyze the causes of different types of cracks. In different axial loading stages, the velocity field types of particles on both sides of cracks are continuously evolving. According to the particle velocity field analysis and the proposed novel way, the types of macroscopic cracks are not directly determined by the types of dominated micro-cracks. Under uniaxial compression, the particles between secondary cracks and pre-existing parallel flaws form a confined compressive member. Under the confinement of lateral particles, secondary cracks appear as shear cracks between pre-existing parallel flaws at the beginning stage of crack initiation.

Published: April 2019

In this work, several kinds of quaternary ammonium-based room-temperature ionic liquids (QA RTILs) are synthesized by alkylation and ion-exchange reactions for the rapid dissolution of cellulose. The applications of cellulose materials have been limited due to their poor solubility in conventional organic solvents, because of a high degree of structural regularity and a large number of hydrogen bonds. The prepared ionic liquids were identified by nuclear magnetic resonance, elemental analysis, and liquid chromatography-mass spectrometry. The results indicated that N,N,N-triethylhexan-1-aminium acetate (N6222OAc), tetrahexylammonium acetate (N6666OAc), and N,N,N,N′,N′,N′-hexaethyldecane-1,10-diaminium acetate (C10(N222OAc)2) exhibited good cellulose-dissolution without any pretreatment. The regenerated cellulose films with a low degree of crystallization of the cellulose II phase were also prepared easily in this process using N6222OAc due to its polar and small cation. These QA RTILs can be used as non-derivatizing solvents for cellulose and can also be easily recycled because of their thermostable and nonvolatile properties.
A Robust Controller for Multivariable Model Matching System Utilizing a Quantitative Feedback Theory: Application to Magnetic Levitation
Authors: Jeyasenthil Ramamurthy , Choi Seung-Bok
Published: April 2019

This paper proposes a systematic feedback controller design methodology for multi-input multi-output (MIMO) uncertain systems using the quantitative feedback theory (QFT). To achieve this goal, the model matching problem was considered and the inversion feedforward controller was designed to improve control performance while reducing the demand on feedback control alone. The proposed method is formulated based on the concept of equivalent disturbance attenuation (EDA) approach in which the uncertain system problem is converted into an external disturbance rejection problem based on a nominal system. This proposed approach exhibiting non-sequential design method result in the suboptimal solution showing design simplicity and computational efficiency compared to the existing method. In order to validate the effectiveness of the proposed control methodology, the MIMO magnetic levitation system as adopted and control performances such as time response were presented in both time and frequency domains.

Published: April 2019

The reinforcement of concrete by using polyolefin fibres may be considered in structural design to meet the requirements of the applicable code rules. To achieve a reliable use of such a composite material, use of full-scale real structures is needed. The conversion of lab testing data into real practice properties is challenging and significantly influenced by various aspects, among which the size effect is a key one. Given that the available literature does not report coinciding conclusions about such an effect on quasi-brittle materials reinforced with fibres, further research is justified. Therefore, this work studies the behaviour of notched beams with three proportional sizes by using self-compacting polyolefin reinforced concrete with a fibre volume fraction of 1.1%. Flexural testing was carried out according to the standard EN-14651, with the results revealing the existence of the size effect. In addition, a reduction of the residual strength identified in the larger specimens was observed in fracture surfaces with equal fibre content.
Analysis of the Correlation between Shielding Material Blending Characteristics and Porosity for Radiation Shielding Films

Published: April 2019

The most important factors in the manufacture of shielded sheets are shielding ratio, light weight, and tensile strength. The base material should provide a light-shielding film with strong physical shock resistance, while maintaining the shielding ratio of lead. Therefore, we studied the correlation between the porosity during the mixing process and the maintenance of the shielding film characteristics. Changes in the shielding ratio can be predicted according to the properties of materials such as polymeric silicon and tungsten oxide. Further, their tensile strength and porosity may change depending on the content of the material. Experiments were carried out for each substance based on the shielding ratio with respect to the processing conditions. For a shielding film using barium sulfate (BaSO4) and polymeric silicon, increasing the porosity by the removal of air in the same manufacturing process resulted in a tensile strength of 6.4 MPa at 22% porosity. For tungsten oxide (WO3), the tensile strength was 10.5 MPa at a porosity of 12%, and for a 0.6 mm sample, the shielding performance was very similar to 0.21 mm of Pb. The porosity during the manufacturing process affected the tensile strength and shielding performance, which were significantly different for each shielding material.

Heating, ventilation and air-conditioning (HVAC) systems play a key role in shaping the built environment. However, centralized HVAC systems cannot guarantee the provision of a comfortable thermal environment for everyone. Therefore, a personalized HVAC system that aims to adapt thermal preferences has drawn much more attention. Meanwhile, occupant-related factors like skin temperature have not had standardized measurement methods. Therefore, this paper proposes to use infrared thermography to develop individual thermal models to predict thermal sensations using three different feature sets with the random forest (RF) and support vector machine (SVM). The results have shown the correlation coefficients between clothing surface temperature and thermal sensation are 11% and 3% higher than those between skin temperature and thermal sensation of two subjects, respectively. With cross-validation, SVM with a linear kernel and penalty number of 1, as well as RF with 50 trees and the maximum tree depth of 3 were selected as the model configurations. As a result, the model trained with the feature set, consisting of indoor air temperature, relative humidity, skin temperature and clothing surface temperature, and with linear kernel SVM has achieved 100% recall score on test data of female subjects and 95% recall score on that of male subjects.

Published: April 2019

The comprehensive characterization of heat waves and extreme hot days is fundamental for policymakers due to its vast implications for human health. This study evaluates extreme temperature changes over the Iberian Peninsula for the present climate and future projections, considering extreme temperature indices, cold/heat waves, and a recovery factor, using the Weather Research and Forecasting model. The projected temperatures show an increase of over 6 °C. An increase in the number of summer days and tropical nights and a decrease in frost days is expected. The number of heat waves and their duration and intensity are expected to increase. The number of heat wave days are expected to increase, with much of the average summer season being under heat wave conditions. The recovery factor is expected to decrease. Cold spells are projected to decrease in terms of number, intensity, duration, and number of spell days, whereas the recovery factor is expected to increase. Heat wave analysis was combined with maximum temperature thresholds to isolate extreme heat waves. The results show an increase in extreme heat wave days, with regions experiencing over 10 heat wave days with maximum temperature surpassing 45 °C for the long-term future.
