Avrupa Kömür Çelik Topluluğu (AKÇT) Antlaşması ile üye devletler daha önce örneği görülmemiş bir şekilde egemenliklerini bir kısmını kendi aralarında oluşturmuş oldukları bir üst kuruma devretmişlerdir. Başarılı ekonomik gelişmelerin ardından Avrupa’daki bu örnek işbirliği, bütün ekonomi alanlarını kapsayacak şekilde Avrupa Ekonomik Topluluğu Antlaşması (AET) ile ekonominin bütün sektörlerine yayılmıştır. AKÇT Antlaşmasın imzalanmış olduğu yıldan bu yana bir çok değişikliğe uğramıştır. Önce Avrupa Ekonomik Topluluğu (AET), sonra Avrupa Topluluğu (AT) ve nihayetinde Avrupa Birliği (AB) adını alarak, üye devletler arasındaki işbirliğini ekonomik alandan siyasi alana geçmesini sağlamıştır. AB, 2016 yılında Büyük Britanya’da yapılan halk oylamasının sonucu ile büyük bir şok yaşamıştır. Büyük Britanya’lıların çoğunlunluğun AB’den ayrılma yönünde oy kullanmış olması, “acaba AB dağılma sürecine mi girdi?” sorusunun oluşmasına sebep olmuştur. Brexit ile başlayan bu sürecin devamında AB’yi çok önemli gelişmelerin beklediği kesindir. Bu süreçte Birliğin geleceği, alınacak önlemler ve belirlenecek siyasete göre şekillenecektir.

Aim. To search for new pharmacogenetic biomarkers of bleeding risk in patients taking rivaroxaban and dabigatran for different indications: atrial fibrillation, endoprosthesis of large joints of lower limbs.

Material and methods. The study enrolled 29 patients (17 patients received dabigatran and 12 –rivaroxaban), who had hemorrhagic complications during taking direct oral anticoagulants. To find new pharmacogenetic biomarkers of bleeding risk, a next generation sequencing (NGS) was performed for selected candidate genes.

Results. Among the patients with bleeding who received dabigatran, 13 variants of the nucleotide sequence showed statistically significant deviation from the population values: 11 in the CES1 gene and 2 in the ABCB1 gene. Among the patients with bleeding who received rivaroxaban, 7 variants of nucleotide sequence showed significant deviation: 4 in the ABCG2 gene, 2 in the CYP3A4 gene, and 1 in the ABCB1 gene.

Conclusion. The identified in this study polymorphisms of candidate genes ABCB1, ABCG2, CES1, CYP3A4 were associated with the risk of bleeding in patients taking rivaroxaban and dabigatran. It makes an important contribution to the pharmacogenetics of direct oral anticoagulants and require additional assessment of clinical significance in further studies.

Published: October 2020

Aim. To study the effect of class III antiarrhythmic drugs (amiodarone and sotalol), and the β-blocker bisoprolol on the spectral parameters of heart rate variability in patients with different forms of atrial fibrillation (AF).

Material and methods. Spectral analysis of heart rate variability of 5-minute electrocardiography intervals was used. The study included patients with newly diagnosed AF and having a duration of the disease from 6 months to 8 years. Arterial hypertension, coronary artery disease, myocardial infarction (in history), conduction disorders and type 2 diabetes mellitus were diagnosed as comorbidities. The following parameters were calculated: the total power (TP) of the spectrum, the power of very low frequencies (VLF), low frequencies (LF) and high frequencies (HF).

Results. In the group of patients with newly diagnosed AF without concomitant diseases after administration of amiodarone, VLF prevails in the spectrum structure, which indicates a significant role of humoral factors in the regulation of heart rate. The power of LF, reflecting the activity of the sympathetic nervous system, prevails over HF power after administration of amiodarone. In patients with newly diagnosed AF, having concomitant diseases, sympathetic influences prevail over parasympathetic ones by 3.6 times after administration of amiodarone. In the group of patients who have reduced the number of comorbidities, the LF/HF decreases and is only 1.66 after administration of amiodarone. The decrease in the number of negative factors is also accompanied by an increase in the influence of the vagus nerve on the activity of the heart. In the study of the effects of sotalol, the LF/HF in this group was twice lower in the group of patients with long-term AF. In patients receiving bisoprolol as antiarrhythmic therapy, the proportion of LF in the group of patients with newly diagnosed AF is 2 times lower, and the proportion of HF is twice higher than in the group of patients with long-term AF.

Conclusion. The effect of antiarrhythmic drugs on the spectral parameters of heart rate variability depends on the duration AF. The presence of concomitant diseases of the cardiovascular system can significantly change the effect of antiarrhythmic drugs on the spectral parameters of heart rate variability and is accompanied by an increase in sympathetic activity. In patients with newly diagnosed AF, amiodarone and sotalol cause a similar effect – the predominance of sympathetic influence; when using bisoprolol, the predominant influence belongs to the vagus nerve. In patients with long-term AF, the opposite effect of drugs is observed: the use of amiodarone is accompanied by a more pronounced influence of the vagus nerve, and bisoprolol – the predominance of sympathetic influence. When using sotalol, sympathetic influences also prevail, more pronounced in patients with newly diagnosed AF.
Halal Tourism in the Context of Tourism Sector in Tunisia: Controversies, Challenges, and Opportunities
Authors: Vandromme Selah
Published: October 2020

This paper examines the development of the tourism industry in Tunisia from its independence in 1956 to contemporary Tunisia with a special focus on the development of halal tourism. In assessing the tourism sector in Tunisia, a typology is used. This typology makes it clear that Tunisia is a prominent tourist destination in several types of tourism, including beach tourism, while in other types it remains underdeveloped. Regarding the emerging form of halal tourism, Tunisia is lagging behind in its development. This may come as a surprise given the fact that Tunisia is a popular tourist destination and a Muslim majority country. Although there are different reasons for this, I would argue that many things can be explained by looking at the political context in Tunisia. The reluctance of government actors hinders the profound development of halal tourism. The policies that have been put forward in the past by Bourguiba and Ben Ali have had an undeniable impact on the general opinion of contemporary Tunisian society on this matter. Even though Tunisia is faced with challenges, Tunisia can still be a suitable country for halal tourism while maintaining other forms of tourism.Keywords: Tunisia, halal tourism, religious tourism, opportunities and challenges.

Published: October 2020

The high-level thick and hard strata are the main reason for the presence of a strong ground pressure during extra-thick coal seam mining, however, there is no active and effective control technology. This paper proposes the method of ground fracturing hard roofs, and the physical simulation was used to study the control effect of ground fracturing on the strata structure and energy release. The results showed that the ground fracturing changed the structural characteristics of the strata, reduced the energy release intensity and overburden movement spatial extent, which had a significant control effect on the ground pressure. The Datong mining area was selected as the engineering background, a ground horizontal well fracturing engineering test was conducted on site, and a 20-m-thick hard rock layer, which was 110 m vertically above from the coal seam, was determined as the fracturing target layer. On-site microseismic monitoring showed that the crack propagation length was up to 216 m, and the height was up to 50 m. On-site mine pressure monitoring showed that the roadway deformation was reduced to 100 mm, the periodic weighting characteristics of the hydraulic supports were not obvious, the ground pressure in the working face was significantly controlled, which proved the ground fracturing successful. Ground fracturing changed the breaking characteristics of the high-level hard strata, which is beneficial to ameliorate the stress concentration in the stope and provide an effective approach of hard rock control.

Published: October 2020

The Parliament, on 29 December 2006, passed a historic legislation called The Scheduled Tribes and Other Traditional Forest Dwellers (Recognition of Forest Rights) Act, 2006, popularly called FRA, 2006, to recognize and vest the forest rights and occupation in forest land in forest dwelling Scheduled Tribes (STs) and Other Traditional Forest Dwellers (OTFDs). One of the objectives of the Act is to strengthen the conservation regime of the forests while ensuring livelihood and food security of the forest dwellers. While recognizing and vesting various rights in forest dwelling STs & OTFDs several welfare schemes to improve the productivity of forest land recognized and thereby to uplift the socio-economic status of forest dwellers have been carried out. Besides, the development rights provided under Section 3(2) for creation of infrastructure etc. in the villages also play an important role in this direction. A study was conducted to assess the FRA’s impact on socio-economic status of the forest dwellers in Madhya Pradesh considering that the State has got extensive forest areas, large forest dwelling tribal communities, presence of diverse agro-ecological zones, and being pioneer in the implementation of FRA. Survey was carried out in six districts viz. Chhindwara, Mandla, Badwani, Khargone, Shahdol and Sidhhi and the result reveals that different welfare schemes implemented for the benefits of forest dwellers and recognized forest land have created overall positive impacts on their socio-economic status, post implementation of FRA 2006.

It is known that optimization of join queries based on average selectivities is sub-optimal in highly correlated databases. Relations are naturally divided into partitions , each partition having substantially different statistical characteristics in such databases. It is very compelling to discover such data partitions during query optimization and create multiple plans for a given query , one plan being optimal for a particular combination of data partitions. This scenario calls for the sharing of state among plans, so that common intermediate results are not recomputed. We study this problem in a setting with a routing-based query execution engine based on eddies. Eddies naturally encapsulate horizontal partitioning and maximal state sharing across multiple plan. The purpose of this paper is to present faster execution time over traditional optimization for high correlations, while maintaining the same performance for low correlations.

Diagnosing a disease leads to proper treatment of a patient. Various diseases are occurred due to hormonal dis-balances within the body. Minor shift of the hormonal concentration within the body fluids, account for various physio-metabolic disruptions. This leads to formation of many diseases. So, regular or periodic diagnosis of the hormones within body fluids are very important in a clinical point of view. To quantify hormones within the body fluids there are a no. of ways to perform. The procedures may be of radioactive principles or non-radioactive ones. These may be Enzyme Linked Immunosorbent Assay (ELISA), Radio-immuno-assay (RIA), Spectroscopy etc. Modern techniques like Time resolved fluorescence, chemiluminescence etc. are also there. Besides, previously used bioassays are there for experimental usage within the laboratory. The ultimate goal is to elevate the speed of sample collection, faster diagnosis of the hormones and thus, proper treatment of the patient by the physician.

This study aims at clarifying the concept and dimensions of consumer rights, and at diagnosing the reality of consumer rights represented in the (right to choose, right to safety, right to be heard and right to be informed). The descriptive approach was the one used for the purpose of this study. The current study was conducted on consumers of some basic goods and services. A facilitated sample consisting of (100) people was used. The blank questionnaire method was used to obtain the primary data.The results show that there is an increase in the frequency of consumer rights violations in light of globalization and the repercussions of the financial crisis due to the Corona virus crisis. It was found that the consumer rights watchdogs knowledge of global consumer rights regulations was very limited, and that their ability to know and meet consumer rights is weak. There are few contributions by researchers in addressing the importance of consumer rights in the Palestinian reality. In addition, there is a retreat in the provision of safety and protection requirements in some of the products offered in the Palestinian consumer market. The role of the government and regulatory authorities such as consumer protection and the Ministry of Economy in providing information of interest and providing protection Sustainable for consumers is weak as well.

As the 21st century globalization, it has become more clear that the evolution of the migration phenomenon will bring drastic changes in the population structure and the appurtenance to a multi-ethnic society will become the social rule. In this context, the relation between the migration decision and the social and economic factors of the origin or destination countries becomes a strategic one. In order to optimize the positive effects of migration, the policies of the specific economic and social fields need to be harmonized with the migration strategies at national and EU level. The article focuses on the influence of the social and economic factors on the migration management at EU level using quantitative research methods. The research results indicated that the main economic and social factors that greatly influence migration management are the manner in which the labour market functions, and in particular its demographic and competitive deficiencies. Scientists, specialists from the competent public authorities can capitalize the results obtained, improving policies and strategies in this field in view of the benefit of the local community and of migrants who want to integrate in the community.

The study was a survey in which questionnaires were administered to 80 respondents. Data analysis and interpretation was conducted through frequency tables and percentages. The study revealed that, students study habits was the major cause of their poor performance in Mathematics. It was also revealed that, problem-based learning was the main activity-based teaching method that could improve upon Mathematics education in the school. It was finally revealed that, teaching effectiveness was the major factor that affected Mathematics education in the school. Attainment of the goals of Mathematics education is largely dependent on the quality of teachers. Therefore, there should be quality teacher development. Opportunities to enrich teachers practices and competencies through in-service training, conferences, seminars and workshops should be provided on a regular basis to help them keep abreast with recent developments in the field of Mathematics education and broaden their knowledge of the subject matter. There should be proper staffing of schools in terms of quality and quantity. Good practices for effective implementation of inquiry-based Mathematics education must be identified and properly implemented. There should also be provision of modern teaching-learning resources in terms of quality and quantity as students need a variety of materials to engage in inquiry-centered learning environment. Finally, if Mathematics courses are properly taught from the lower level, this will lay a sound foundation for Mathematics education at the higher level.
DENTAL FLUOROSIS AND PERIODONTAL DISEASE: AN OVERVIEW
Authors:   ijar, Yadav Ashish
Published: October 2020

Aim: The aim of this review is to discuss various effects of fluoride on hard and soft tissues of the periodontium and its importance in human life. Background : Fluoride is an essential element for life and is one of the trace elements normally present in the body. It is abundant in the environment and the main source of fluoride to humans is drinking water. Fluoride gets accumulated in hard tissues of the body and has been known to play an important role in mineralization of bone and teeth. The behaviourof fluoride ions in the human organism can be regarded as that of double-edged sword. In small amounts, it is known to have beneficial effects on dental health. On the other hand, excessive chronic intakes can result in adverse effects including the development of dental fluorosis in children and/or skeletal fluorosis in both children and adults. Although effect of fluoride on caries has been discussed in painstaking details through various studies but the effect of fluorosis on the periodontium yet remains in shadow. Review Results : Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. Even after continuing with the age old logic of structural changes that take place in mottled enamel it can be said with scientific plausibility that this factor of surface roughness can or must influence some of the variables in this multifactorial disease of periodontitis. This surface roughness is conducive for the bacteria to survive as well as make it difficult for scaling and root planing in fluorosed teeth. This could also jeopardize the effectiveness of the regular oral hygiene procedures. Conclusion : Dental fluorosis is not only a cosmetic problem that impairs social well-being but also affects the oral health related quality of life. Fluorosis continues to be an important problem, both for the affected individuals and for public health. More and more areas are being discovered regularly that are affected by fluorosis in different parts of the country. But ultimate solution for this fluoride menace remains to be the principal of Precaution is better than cure. Clinical Significance : Considering the role of fluorosis on hard and soft tissues and all the risk factors of periodontitis, fluorosis can be recommended strongly as an environmental risk factor for periodontitis. To be defined as one of the etiological (environmental) agent of periodontal disease requires further research studies with greater sample size from varying areas globally.

Competence-based education has gained in popularity at many countries. Competence is regarded as the possession and development of integrated skills, knowledge, appropriate attitudes, and experience for the successful performance of ones life roles. A new concept is gaining great relevance in the clinic medical education context: Entrustable Professional Activities (EPAs) these activities allow curricular development of competencies, no longer in the classroom. EPAS have been identified for many graduate clinical education programmes, but none for basic sciences disciplines. With the idea of transfer EPA concept to the development and assessment of basic science competencies, this work offers: (1) a EPAS-competencies matrix to work the competency E2 described by the Association of American Medical College (linked with research skills) (2) the development of a complete EPA model. The proposal opens a line to discuss the implications and challenges that this concept-transfer offers.

Authors:   ijar, Sayad Zahra , Dani Bouchra , Boulaadas Malik
Published: October 2020

Introduction: The infraorbital schwannoma or neuroma is a rare benign tumor of the orbit. Its clinical and radiological presentation is not very specific. Its diagnosis is essentially histological. Observation: We report the case of a 46-year-old woman, diabetic under treatment, consulting for an irreducible, non-axial and non-pulsatile exophthalmos. Clinical examination of the left eye found visual acuity corrected to 8/10 without limitation of ocular motility or diplopia. The examination of the right eye is unremarkable.The orbital CT objectified a mass measuring 25.3mm × 13.8mm, homogeneous of the floor of the left orbit, pushing the eyeball up and out. The orbital floor was pushed inferiorly by the mass however, its integrity was preserved. Tumor excision was performed via the sub-ciliary cutaneous incision with reconstruction of the floor by an iliac crest graft. The histological analysis allowed us to have a definite diagnosis of schwannoma. Conclusion:The schwannoma is a rare tumor of the orbit. Its diagnosis is established solely by anatomopathological study of the operative specimen. Its treatment is based on a complete surgical excision to avoid any recurrence.

Leadership engenders an essential element for organisations to develop business strategies and achieve their goals. This research aims to examine the impact of laissez-faire leadership style on organisational commitment (OCOM) in health care centers in Qatar. The researcher adopted a quantitative approach, using a self-administered questionnaire to collect the primary data. The sample consisted of 218 leaders and supervisors from five healthcare centers in Qatar selected employing non-random sampling. The study indicated a significant positive relationship existed between laissez-faire leadership and OCOM. Moreover, leadership behavior significantly impacted OCOM behaviors. but in different degrees: continuance commitment and normative commitment to a higher extent, and affective commitment less so. Also, the results showed the percentage to which Laissez-Faire leadership style was practiced, in the sample, to be high.

Polymerase Chain Reaction (PCR) is a widely used technique in the field of molecular biology to rapidly make very large number of copies of a specific DNA sample for detailed studies. The success of the technique however is dependent on the on the quality, i.e purity of the extracted DNA specimen. The aim of this study was to evaluate the quality of extracted DNA from pectinase producing yeast to determine the suitability of the extraction method to produce pure extract without non-inhibiting substances.In this study, DNA extracts from six (06) isolates of pectinase-producing yeasts were quantitatively and qualitatively analyzed using NanoDrop spectrophotometry and agarose gel electrophoresis methods. These analyses showed that the concentration of DNA extracts from the isolates evaluated by the NanoDrop spectrophotometric method ranged from 403.8 to 1082.4 ng/µL and the purity index A 260/280 was between 2.03 and 2.11. In sum, agarose gel electrophoresis showed that the intensity of the DNA bands was irregular and not necessarily in line with the data provided by the NanoDrop spectrophotometry.

Sri Lanka has initiated major development programmes over the years to enrich its trade facilitation. Out of all, one of the main objectives is to transform Sri Lanka into a logistics hub to smoothly operate international trade. The perspective of the logistics sector in introducing such programmes is helpfulin planning and finalizing development policies. Potential investors investigate LPI as a multi-dimensional indicator before placing investment decisions.When compared to other competing countries in the region, the LPI scores of Sri Lanka have not been satisfactory.Quality of trade and transport related infrastructure dimension is underperforming since 2007.In that scenario, it is a contemporary requirement to evaluate the logistics performance index and test the construct validity of the index in Sri Lanka.Therefore, the objective of this research was to conduct a confirmatory factor analysis for the infrastructure dimension of logistics performance index based on Sri Lanka. The results were grounded on a questionnairesurveyfrom a sample of 60 industry professionals from 20 freight forwarding companies.The date collection was limited to registered freight forwarding companies atthe Sri Lanka Freight Forwarders Association.The indicators of each dimension of the infrastructure dimension of LPI was verified through a Confirmatory Factory Analysis using IBM SPSS Amos. The study confirms the construct validity of the infrastructure dimension and the results were in consistent with the conceptual framework of LPI.

Adolescence is identified as a transition phase where individuals undergo dramatic changes in terms of their cognitive growth. During this time, the heightened awareness of personal and sexual identity leads to greater prioritization of social interaction and popularity. Self-esteem and confidence are measured on the basis of ones social value which can have both positive and negative impacts. In this paper, we study how individuals going through this complex phase of psychological development are dealing with the effects of the COVID-19 pandemic of 2020. With schools and other educational institutes remaining shut down and social distancing norms established, they are undergoing a phenomenon that has not been experienced by previous generations. Studies on isolation often show psychological outcomes such as low mood, poor sleep quality, impaired immunity and cognitive decline, among other symptoms. In this regard, this paper aims to identify the effect of COVID-19 on high school students of Delhi NCR in India, determining their psychological state and analyzing its impact on academic and interpersonal goals. There is also an attempt to predict repercussions of the same in the foreseeable future. Results are based on a questionnaire that will be distributed among high school students, and the discussion and analysis will be drawn based on an interpretation of the same.

The condition of beaches in Indonesia is currently quite concerning. Indonesia's mangroves and coastal sand are in danger of being damaged. Commitment from all parties is needed to overcome coastal damage. If not, the negative impact will be dangerous for the existence of coastal communities. Damage to coastal is a serious threat to the surrounding ecosystem, even tends to harm humans. Not only waste carried by the flow into the sea, but also garbage disposed of around the coastal areas of the sea and poor land management are clearly some actions that can reduce the carrying capacity of the environment. This carriage a serious threat to the environment. The beach in Subang district, West Java has quite severe coastal damage. Analysis of shoreline changes is needed to overcome the damage to the coast. The method used to analyze shoreline changes is through satellite mapping using Google Earth. The results obtained from 10 years of coastline satellite mapping in Subang Regency are changes in coastline and area that occur due to erosion and/or accretion. These results will help to challenge erosion and/or accretion. The next step can be made a coastal protection in the form of mangrove plants or coastal protection structures.

Research into the quality of people's lives is a current issue addressed by a large number of researchers. Subjective measures indicate differences in real living conditions. The well-being of people is examined within the eudaimonic and hedonistic approach. As a part of the hedonistic approach, life satisfaction is largely examined. The hedonistic approach refers to social and psychological well-being. In this study, we investigated both approaches to examine the overall well-being of students. The participants' general satisfaction with life is very high. The survey of life satisfaction in certain domains shows that students are most satisfied in the domains of personal relationships, community and personal safety. The well-being of the participants is high. Participants exhibit high levels of emotional and psychological well-being, which are related to eudaimonia. Full-time students are more satisfied with life and have higher levels of subjective well-being than part-time students. No differences in eudaimonic well-being were found.
