Resumo: A odontologia vem buscando cada vez mais métodos de reabilitação dentária que sejam menos traumáticos e eficazes estética e visualmente falando. Sob esse aspecto, os implantes dentários têm se desenvolvido cada vez no intuito de garantir a satisfação dos pacientes, através de avanços tecnológicos como o da Nanosuperfície de Titânio. Assim, o presente estudo objetiva abordar a questão das superfícies de implantes de titânio no que se refere à sua capacidade de estímulo na formação óssea, por ser uma técnica que diminui o tempo de osseointegração e, consequentemente, a duração do processo e recuperação do paciente. Para tanto, foi realizada uma revisão bibliográfica em bases de dados eletrônicas acerca do tema, que comprovassem a diminuição de tempo do trabalho do profissional da Odontologia e uma melhor qualidade no que se refere aos implantes dentários, através da análise de três marcas nacionais a fim de comprovar sua eficácia. Palavras-chave: Implante dentário. Nanosuperfície de Titânio. Osseointegração. ---Abstract: Dentistry is increasingly seeking dental rehabilitation methods that are less traumatic and effective aesthetically and visually. In this regard, dental implants have been increasingly developed to ensure patient satisfaction, through technological advances such as the Titanium Nano-surface. Thus, this study aims to address the issue of titanium implant surfaces in terms of their ability to stimulate bone formation, as it is a technique that reduces the time of osseointegration and, consequently, the duration of the process and patient recovery. To this end, a bibliographic review was carried out in electronic databases on the subject, which could prove the reduction of time in the work of the dentistry professional and a better quality regarding dental implants, through the analysis of three national brands to prove its effectiveness. Keywords: Dental implant.

Abstract Although the overall success rate of implant dentistry is very high, dental implants occasionally fail. It is essential for the clinician to recognize unhealthy implants and to determine whether they are ailing, failing, or failed prior to beginning any salvage efforts. Ailing and failing implants are amenable to therapy. Implants diagnosed as failed should be removed. This review provides the reader with information on non-surgical and surgical therapies available for managing ailing and failing implants. Undoubtedly, the best steps to avoid encountering ailing or failing implants involve proper case selection, excellent surgical technique, placing an adequate restoration on the implant, educating the implant patient to maintain meticulous oral hygiene, and evaluating the implant both clinically and radiographically at frequent recall visits.

Background: Research shows that there is a high prevalence of suicide among nurses. Despite this, it has been 15 years since the last literature review on the subject was published. Aim: The aim of this article is to review the knowledge currently available on the risk of suicide among nurses and on contributory risk factors. Method: A search was conducted in electronic databases using keywords related to prevalence and risk factors of suicide among nurses. The abstracts were analyzed by reviewers according to selection criteria. Selected articles were submitted to a full-text review and their key elements were summarized. Results: Only nine articles were eligible for inclusion in this review. The results of this literature review highlight both the troubling high prevalence of suicide among nurses as well as the persistent lack of studies that examine this issue. Conclusion: Considering that the effects of several factors related to nurses' work and work settings are associated with high stress, distress, or psychiatric problems, we highlight the relevance of investigating work-related factors associated with nurses' risk of suicide. Several avenues for future studies are discussed as well as possible research methods.

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.

Objective: Focal cartilage injuries, and posttraumatic osteoarthritis (OA) in the wrist are likely common and a cause of wrist pain. To estimate the incidence of cartilage lesions and to understand the pathomechanisms leading to wrist cartilage injuries and OA, a literature review on the subject was performed combined with a presentation of one of the authors’ own experience. Design: This study includes a literature review of the topic. As a comparison to the review findings, the observations of one of the authors’ consecutive 48 wrist arthroscopies, were assessed. PubMed, Scholar, and Cochrane databases were searched using the keywords “cartilage injury AND wrist AND treatment” and “wrist AND cartilage AND chondral AND osteochondral AND degenerative OA.” :Result A total of 11 articles, including 9 concerning chondral and osteochondral repair and treatment and 2 regarding posttraumatic OA, were retrieved. The cartilage repair treatments used in these articles were drilling, osteochondral autograft, juvenile articular cartilage allograft, and chondrocyte implantation. One article displayed concomitant cartilage injuries in displaced distal radius fractures in 32% of the patients. The review of our findings from a 1-year cohort of wrist arthroscopies showed 17% cartilage injuries. Conclusion: There is a lack of knowledge in current literature on cartilage injuries and treatment, as well as posttraumatic OA in the wrist. Cartilage injuries appear to be common, being found in 17% to 32% of all wrist arthroscopies after trauma, but no guidelines regarding conservative or surgical treatment can be recommended at the moment. Larger prospective comparative studies are needed.

The COVID-19 pandemic highlighted the necessity of good quality and adequate quantity of healthcare infrastructure facilities. Healthcare facilities were provided for COVID-19 facilities with improvisation and supplementary lateral infrastructure from other sectors. However, the main point of contemplation going into the future was regarding how to quickly develop healthcare facilities. The subject domain of ‘industrial engineering’ (IE) and its associated perspectives could provide some key insights regarding this. The authors undertook a conceptual literature review and provided theoretical argumentation toward this. The findings provided insights regarding the application of industrial engineering concepts in healthcare facilities and services.

The main purpose of this paper is to present what the Industry 5.0 phenomenon means in the supply chain context. A systematic literature review method was used to get evidence from the current knowledge linked to this theme. The results have evidenced a strong gap related to Industry 5.0 approaches for the supply chain field. Forty-one (41) publications, including conference and journal papers, have been found in the literature. Nineteen (19) words, which were grouped in four (4) clusters, have been identified in the data analysis. This was the basis to form the four (4) constructs of Industry 5.0: Industry Strategy, Innovation and Technologies, Society and Sustainability, and Transition Issues. Then, an alignment with the supply chain context was proposed, being the basis for the incipient Supply Chain 5.0 framework and its research agenda. Industry 5.0 is still in an embryonic and ideal stage. The literature is scarce and many other concepts and discoveries are going to emerge. Although this literature review is based on few available sources, it provides insightful and novel concepts related to Industry 5.0 in the supply chain context. Moreover, it presents a clear set of constructs and a structured research agenda to encourage researchers in deploying further conceptual and empirical works linked to the subject herein explored. Organizations’ leadership, policymakers, and other practitioners involved in supply chains, and mainly those currently working with Industry 4.0 initiatives, can benefit from this research by having clear guidance regarding the dimensions needed to structurally design and implement an Industry 5.0 strategy. This article adds valuable insights to researchers and practitioners, by approaching the newest and revolutionary concept of the Industry 5.0 phenomenon in the supply chain context, which is still an unexplored theme.

Sustainable development was defined by the UN in 1987 as development that meets the needs of the present without compromising the ability of future generations to meet their own needs, and this is a core concept in this paper. This work acknowledges the three dimensions of sustainability, i.e., economic, social, and environmental, but its focus is on this last one. A digital twin (DT) is frequently described as a physical entity with a virtual counterpart, and the data, connections between the two, implying the existence of connectors and blocks for efficient and effective data communication. This paper provides a meta systematic literature review (SLR) (i.e., an SLR of SLRs) regarding the sustainability requirements of DT-based systems. Numerous papers on the subject of DT were also selected because they cited the analyzed SLRs and were considered relevant to the purposes of this research. From the selection and analysis of 29 papers, several limitations and challenges were identified: the perceived benefits of DTs are not clearly understood; DTs across the product life cycle or the DT life cycle are not sufficiently studied; it is not clear how DTs can contribute to reducing costs or supporting decision-making; technical implementation of DTs must be improved and better integrated in the context of the IoT; the level of fidelity of DTs is not entirely evaluated in terms of their parameters, accuracy, and level of abstraction; and the ownership of data stored within DTs should be better understood. Furthermore, from our research, it was not possible to find a paper discussing DTs only in regard to environmental sustainability.

It has been known for some time that the torsional vibration of reciprocating engines and pumps cannot be modelled accurately by representing the reciprocating mechanism by a constant inertia. There have been many publications describing better models than those that use constant inertia and these indicate that the effective inertia of a reciprocating mechanism varies with angular position. The major component of this variation is a twice per revolution cyclic effect—hence the term ‘secondary inertia’. The consequences of this secondary inertia effect can be serious for torsional vibration causing ‘secondary resonance,’ and even instability. This paper contains a review of the current literature on the subject and introduces some recent work by the authors.
