In the first part of this literature review, published in October 2019 in this journal, we summarized the conceptual background of the oral microbiota, and the main methods used in microbiology to characterize oral organisms. We also presented the most studied bacteria species in the oral microbiota. In this second part, we will discuss the evidence regarding the biological plausibility linking the oral microbiota dysbiosis and systemic diseases, as well as the main factors and mechanisms suspected in this association.

In recent decades, a body of literature examining the relationships between oral health and general health has rapidly developed. However, the biological mechanisms involved in explaining such relationships have not been fully described. Recent evidence has suggested that these relationships could be partially explained by the composition and interaction of the microbiome/microbiota between local and systemic body sites. For instance, it has been suggested that intestinal microbiota could have effects on non-communicable diseases, such as diabetes or cardiovascular diseases. The objective of this study is to explore current evidence of the link between oral and systemic diseases, to discuss whether oral microbiome/microbiota could represent an unexplored biological pathway partially explaining those relationships. A non-systematic review of the literature was carried out using keyword searches in Pubmed from February to May 2019. The ultimate goal was to present recent scientific evidence to update the general knowledge on this topic to professionals in dentistry. This review is divided in two parts for journal publication; however, it is intended to be used as one piece. In this first part, we will summarize the conceptual background of oral microbiome/microbiota, we will describe the main methods used in microbiology to characterize oral organisms, and will present the main composition of bacteria in oral microbiome/microbiota. The second part highlights the main evidence regarding the biological plausibility that links oral microbiome and systemic diseases and we will conclude with some future research recommendations. Taking into account the role of oral microbiota in the development of systemic diseases could change the main paradigm of how oral health is currently conceptualized by dental professionals.

It has been known that both in the world and in Turkey a continuous change has been experienced in the provision of health services in recent years. In this sense by adopting the customer(client) focused approach of either public or private sector hospitals; it has been seen that they are in the struggle for presenting a right, fast, trustuble, comfy service. The purpose of this research is to measure the satisfaction degree, expectations and perceptions of the patients in Karabük State Hospital through comparison. In this context, the patient satisfaction scale which has been developed as a result of literature review has been used and by this scale it has been tried to measure the satisfaction levels of the patients in terms of material and human factors which are the two main factors of the service that was presented. In the study, with the scales of Servqual and 0-100 Points together, in the part of the analysis MANOVA have been used. The expectations and the perceptions of the patient has been compared first by generally and then by separating to different groups according to the various criterias and in thisway it has been tried to be measured their satisfaction levels. According to the results that were obtained, although, the satisfaction levels of the patients who have taken service from Karabük State Hospital are high in terms of thedoctors and the nurses; it has been reached to the result that their satisfaction levels are low in terms of the materials that have been used at the presenting of the service and the management.

The COVID-19 pandemic has had an unprecedented impact on the labor market. The psychological pressure and uncertainty caused by the current changing workplace environment have led to negative consequences for workers. Considering the predictive relationship between employee engagement and wellbeing and in light of this unprecedented situation that affects workers of all the industries worldwide, this study aims to identify the key main drivers of employee engagement that can lead to employee wellbeing in the current context. Through a literature review, a theoretical model to strengthen engagement in times of COVID-19 is proposed. The main factors are conciliation, cultivation, confidence, compensation, and communication. Whereas prior to the pandemic, firms had already understood the need to achieve this, it is now considered a vital tool for staff health and wellbeing. This article makes two main contributions. First, it provides a model for boosting employee engagement, and therefore, wellbeing. Second, managerial suggestions are made to apply the theoretical model.

The thermal environment is one of the main factors that influence thermal comfort and, consequently, the productivity of occupants inside buildings. Throughout the years, research has described the connection between thermal comfort and productivity. Mathematical models have been established in the attempt to predict changes in productivity according to thermal variations in the environment. Some of these models have failed for a number of reasons, including the understanding of the effect that several environment variables have had on performance. From this context, a systematic literature review was carried out with the aim of verifying the connection between thermal comfort and productivity and the combinations of different thermal and personal factors that can have an effect on productivity. A hundred and twenty-eight articles were found which show a connection between productivity and some thermal comfort variables. By means of specific inclusion and exclusion criteria, 60 articles were selected for a final analysis. The main conclusions found in this study were: (i) the vast majority of research uses subjective measures and/or a combination of methods to evaluate productivity; (ii) performance/productivity can be attained within an ampler temperature range; (iii) few studies present ways of calculating productivity.

Quality management is considered one of the most important obstacles facing the construction industry in Sudan. The application of a quality assessment system contributes to the development of quality in projects as it is possible to measure the quality in projects. This paper aims to introduce one of the quality assessment systems, which is the system followed and applied in the Singapore (CONQUAS). This system assesses quality based on structural, architectural, mechanical and electrical work. The paper also aims to study the factors affecting the application of the quality assessment system in Sudan. The study is carried out in the region of Khartoum. The study is focusing on the construction projects. The study is carried out by questionnaires and other literature review. The respondents are consultants and contractors. The data has been distributed and analyzed by using the Average Index. From the study it was found that CONQUAS standard is assessed the building based on workmanship standards by the assessors from the BCA on site using standard score sheets. The assessment is done throughout the construction process for structural, mechanical and electrical works, and from questionnaire results the main factors affect construction industry in Sudan is lack of standardization in Sudan. The author recommended that more study shall be conducted to identify factors affecting quality in Sudanese construction industry and how to improve the quality.

RESUMOO uso de soluções anestésicas é realizada quase que diariamente pelos profissionais de odontologia. Entretanto, os anestésicos locais disponíveis no mercado apresentam-se sob a forma de soluções com composições e concentrações variadas, tanto com relação ao sal anestésico, vasoconstritor e seu preservativo. Talvez, pela grande variedade de associações, possa surgir diversas dúvidas quanto à melhor escolha durante a prática clínica diária, principalmente quando o mesmo apresenta algum tipo de doença sistêmica. Com isso, o objetivo desse trabalho é realizar uma revisão de literatura das melhores indicações e possíveis contraindicações de soluções  anestésicas locais disponíveis no mercado nacional, relacionando com doenças sistêmicas que comumente são atendidas na clínica odontológica.Palavras – Chave: Odontologia; Anestésico local; Cirurgia oral. ABSTRACT The use of anesthetic solutions is performed almost daily by dental professionals. However, the local anesthetics available on the market come in the form of solutions with varying compositions and concentrations, both with respect to the anesthetic salt, vasoconstrictor and its preservative. Perhaps, due to the wide variety of associations, several doubts may arise regarding the best choice during daily clinical practice, especially when it presents some type of systemic disease. Thus, the objective of this work is to carry out a literature review of the best indications and possible contraindications for local anesthetic solutions available in the national market, relating to systemic diseases that are commonly seen in the dental clinic. Key words: Dentistry; Local anesthetic; Oral surgery.

FinTech, a compound term for financial technology, signifies the usage of technology to provide financial assistance. Ever since its evolution FinTech has been growing tremendously, despite its positive and negative aspects. In the literature review, there are many factors affecting the adoption of FinTech. It was found that the ease of use of technology (Technology Acceptance Theory), investment decisions in crowdfunding (Decision Theory), and the risks involved in the adoption of FinTech (Prospect Theory) are the main factors that might affect the adoption of FinTech. However, there is a paucity of studies linking all these factors in the adoption of FinTech using these theories. This research project investigates the influence of these factors in the adoption of FinTech. In order to analyze these factors, a questionnaire was used. As a result, it was found that there is a positive relationship between the ease of use and FinTech's adoption; between FinTech's adoption and investment decisions in crowdfunding and between the level of risks when adapting to FinTech. Keywords: FinTech; Factors; Bahrain; Adoption; Financial Institutions

The purpose of this paper is to review the literature on various theories that are used in organisations today to determine executive compensation. This paper analyses the relevance of the theories that are used to determine CEO compensation in modern corporations. The paper makes an attempt to review extensively the literature on CEO compensation. This paper looks at the concerns of sixteen theories of executive compensation. This paper further analyses the special features that are associated with CEO pay. These features help us to understand the problems that experts on executive pay experience when they try to define the exact CEO pay when compared to other rewards that are non financial. The drivers of executive pay are quantified and qualified in order to provide the conceptual background needed to understand the core factors that determine executive pay. Therefore the role of institutional investors in driving managerial salary is explored in detail. Finally, the effects of firm size and good corporate governance on executive pay are carefully analysed.
