In the COVID-19 outbreak context, some industries were seriously affected, and the T&T (travel and tourism) industry is unarguably one of those industries. As the world is slowly moving towards a recovery stage, T&T is lagging in the recovery process, mainly because of people’s perception of safety and a new, more cautious behavior when buying products that are not essential for survival, such as T&T products. In order to discover sustainable recovery paths for the industry and the real impact of the COVID-19 outbreak on consumer perceptions and purchasing behavior, the current quantitative research was developed on the basis of two different representative samples in two different moments: May 2020 and December 2020, with a focus on Romania’s population. The main results indicate that the COVID-19 pandemic has influenced travel patterns and habits regarding philological and economic factors. Psychological factors, primarily the fear of contamination, impact travelers’ willingness to travel and the conditions and preferences for vacation destinations. At least in the medium term, people will avoid traveling in large groups and being in crowded places. Hygiene and health conditions in the host destination can represent essential factors in travel decisions. Confronted with a cautious clientele, tourism businesses (such as transport, accommodation, and catering) should further enhance their hygiene conditions to restore confidence. Moreover, communication is essential in these challenging times to tackle travelers’ fear and concerns.

The sustainable consumption and integration of digital solutions with respect to sustainable consumption have been encouraged by the new European circular economy action plan. Digital adoption has been accelerated by the COVID-19 pandemic; companies have been challenged to rapidly adapt to the constant evolution of consumer needs and expectations, leading to valuable insights into the advancement of green business practices and a consequent rethinking of their business model. The purpose of this paper is to investigate the major shifts in sustainable consumer behavior on the Romanian retail market within the context of the Green European Deal, and retailers’ priorities in agilely adapting to these significant evolutions. Based on a comprehensive literature review on these major shifts and significant evolutions at the national and international levels, a quantitative study was carried out to evaluate the Romanian retail market and identify the major challenges faced by retailers in dealing with the new set of priorities. The data collection was conducted via a survey used in the retail environment, applied within a Romanian supermarket chain. The Romanian retail sector has a particular configuration, which may have an impact upon the study’s generalizability. Located in Central and Eastern Europe at the crossroads of the EU, the Commonwealth of Independent States (CIS), and the Middle East, Romania is a leading destination for foreign direct investment, and it is recognized for the similarities of its distribution and sales channels, the range of its retail outlets, and the local retail market dominance on the Big Box segment by reputed major retailers. A spectacular evolution is recorded in Romania’s e-commerce market, including from the point of view of the long-standing and memorable traditional relationship between Romania and China which was confirmed more recently by Romanian consumers who prefer to buy online from stores in China. Our consumer research provides retailers with deep consumer insights with regard to their priorities in their agile adaptation. According to our research, Romanian consumers are environmentally concerned consumers, displaying an increased awareness about the important role they play with respect to impacting sustainable production and consumption by adopting green purchase behavior. Our study also points to the fact that retailers, although faced with challenges in targeting consumers with customized messages to reinforce their brand perception on sustainability issues, do pay considerable attention to sustainability as a personal value embraced by consumers and are willing to focus on digitizing their business processes to enable new, sustainable business models.

This study examines the influence of eco-innovation capability on sustainability driven innovation practices in SMEs. In this study, eco-innovation capability is represented by four factors—internal setting, strategies, operations and structure—while sustainability driven innovation practices are represented by three types of practices—process, organizational and product. The direct relationship between eco-innovation capability and sustainability driven innovation practices is statistically tested by using a sample of 397 Romanian manufacturing small and medium-sized enterprises using PLS–SEM and SmartPLS software. The results show that the development of eco-innovation capability has a direct and positive effect on sustainability driven innovation practices employed in manufacturing SMEs by encouraging them to get involved in cleaner production practices, waste handling and recycling on a regular basis or integrate eco-efficiency into their operations, develop new channels for sustainable products or integrate customers’ suggestions or complaints, implement environment management systems, use eco-friendly raw materials or focus on new product development, for instance. Therefore, the paper extends the literature dedicated to eco-innovation by shedding some light on what to focus on when building eco-innovation capability.

Psoriasis is a chronic inflammatory condition that is polygenic and multisystemic, impacting approximately 2–3% of the global population. The onset of this disease is influenced by an intricate interplay of genetic and environmental factors, predisposing individuals to the psoriasis phenotype. The complex pathogenesis of psoriasis contains certain key aspects found in other autoinflammatory and autoimmune dermatological diseases. Among these, vitiligo, alopecia areata, hidradenitis suppurativa, vitiligo, connective tissue diseases, bullous dermatoses, and atopic dermatitis are conditions that share overlapping immune system dysfunction, making their relationship with psoriasis particularly significant. For our research, we explored various terms including “shared”, “concomitant”, “coincident”, “overlap”, “coexist”, and “concurrent”, in relation to conditions such as “psoriasis”, “alopecia areata”, “hidradenitis suppurativa”, “atopic dermatitis”, “vitiligo”, “bullous pemphigoid”, “pemphigus vulgaris”, “lupus erythematosus”, “dermatomyositis”, and “systemic sclerosis.” Additionally, we used specific search queries like “atopic dermatitis overlapping syndrome” and “psoriasis and vitiligo concomitant disease” in the PubMed and Web of Science databases. While distinct in their clinical presentation, the skin diseases related to psoriasis may become associated, complicating diagnosis and treatment. In this narrative review, the complex pathophysiology of psoriasis is described, along with its close relationship to other skin conditions. This review provides an exhaustive description of both immunological and non-immunological pathways contributing to their development. Understanding the intricate interconnection between psoriasis and these conditions is of interest to scientists in developing novel research directions and to clinicians in providing holistic care, as managing one condition may influence the course of others.

Tattooing is the procedure of implanting permanent pigment granules and additives into the dermal layer of the skin, serving various purposes such as decoration, medical identification, or accidental markings. There has been a significant rise in the popularity of decorative tattooing as a form of body art among both teenagers and young adults. Thus, the incidence of tattoos is increasing, with expanding applications such as permanent makeup, scar camouflage, nipple–areola, lips, and eyebrows tattooing, and utilization in oncological radiotherapy such as colon marking. However, there have been reported a broad range of adverse reactions linked to tattooing, encompassing allergic reactions, superficial and deep cutaneous infections, autoimmune disorders induced by the Koebner phenomenon, cutaneous tumors, and others. These reactions exhibit different onset times for symptoms, ranging from immediate manifestations after tattoo application to symptoms emerging several years later. Given the limited information on a tattoo’s side effects, this review aims to elucidate the clinical spectrum of cutaneous complications of tattoos in different patients. The analysis will investigate both allergic and nonallergic clinical presentations of tattoo-related side effects, microscopic findings from skin biopsies, and therapeutic outcomes. This exploration is essential to improve our understanding of tattoo-related cutaneous complications and associated differential diagnoses and highlight the significance of patient awareness regarding potential risks before getting a tattoo.

Technological evolution has contributed to considerable changes in the learning methods used today. If a few years ago, before the technological boom, students relied only on their memory capacity, on notes on sheets of paper and written materials (in the form of course materials, books, or textbooks), today the process of learning is significantly facilitated by the means and techniques involved in the use of technology, such as artificial intelligence, smartphones, and tablets, which are rapidly replacing bulky desktop computers and outdated textbooks used in the learning process. Moreover, blockchain technology can also be used as a motivational factor for developing learning abilities by implementing a system that can bring students credit points convertible into cryptocurrencies or online badges. Studies conducted in the field show that students’ motivation for learning and creativity is significantly improved with the help of this reward system. In this article, two specialized studies were conducted (in Romania), one on the perception of teachers in the university environment towards the use of new technologies in the learning process (artificial intelligence, smartphones, and tablets), and the other on the perception of students on the technological integration of blockchain (by implementing a system that can bring students credit points convertible into cryptocurrencies or online badges to certify their knowledge) in the learning process and measuring their satisfaction.
