Plastics are very useful materials and present numerous advantages in the daily life of individuals and society. However, plastics are accumulating in the environment and due to their low biodegradability rate, this problem will persist for centuries. Until recently, oceans were treated as places to dispose of litter, thus the persistent substances are causing serious pollution issues. Plastic and microplastic waste has a negative environmental, social, and economic impact, e.g., causing injury/death to marine organisms and entering the food chain, which leads to health problems. The development of solutions and methods to mitigate marine (micro)plastic pollution is in high demand. There is a knowledge gap in this field, reason why research on this thematic is increasing. Recent studies reported the biodegradation of some types of polymers using different bacteria, biofilm forming bacteria, bacterial consortia, and fungi. Biodegradation is influenced by several factors, from the type of microorganism to the type of polymers, their physicochemical properties, and the environment conditions (e.g., temperature, pH, UV radiation). Currently, green environmentally friendly alternatives to plastic made from renewable feedstocks are starting to enter the market. This review covers the period from 1964 to April 2020 and comprehensively gathers investigation on marine plastic and microplastic pollution, negative consequences of plastic use, and bioplastic production. It lists the most useful methods for plastic degradation and recycling valorization, including degradation mediated by microorganisms (biodegradation) and the methods used to detect and analyze the biodegradation.

Advances in early diagnosis, treatment, and postoperative care have resulted in increased survival rates among children with congenital heart disease (CHD). Research focus has shifted from survival to long-term follow-up, well-being, daily life experiences, and psychosocial consequences. This study explored the everyday experiences of children with CHD and of their parents living in the Palestinian West Bank. Interviews with nine children aged 8 to 18 years with CHD and nine parents were analyzed using content analysis. The overall theme that emerged was facing and managing challenges, consisting of four themes: sociocultural burden and finding comfort, physical and external limitations, self-perception and concerns about not standing out, and limitations in access to health care due to the political situation. To provide optimum care for children with CHD and their parents, health care providers and policy makers must understand the negative consequences associated with sociocultural conditions and beliefs about chronic illness.

Plastic Degradation

Abstract— The growing worldwide production of synthetic plastics leads to increased amounts of plastic pollution. Even though microbial degradation of plastics is known to be a very slow process, this capacity has been found in many bacteria, including invertebrate symbionts, and microscopic fungi. Research in this field has been mostly focused on microbial degradation of polyethylene, polystyrene, and polyethylene terephthalate (PET). Quite an arsenal of different methods is available today for detecting processes of plastic degradation and measuring their rates. Given the lack of generally accepted protocols, it is difficult to compare results presented by different authors. PET degradation by recombinant hydrolases from thermophilic actinobacteria happens to be the most efficient among the currently known plastic degradation processes. Various approaches to accelerating microbial plastic degradation are also discussed.

Online gaming, as fun as it is, has the potential to create problems of playing excessively. Even though many people play excessively and have problems on their daily functioning, there are excessive game players who function well in their daily life (Charlton, 2010). This might be caused by good self-control in the individuals. Self-control is defined as the ability to control thoughts, emotion, behavior, and wishes in order to attain higher reward (goals) and avoid being punished or having negative consequences (Vohs, dkk., 2008). Self control will affect someone in conflicting situation among different things. This research aims to seek self control components and processes among non problematic MMORPG gamers. In depth interview with two non problematic MMORPG gamers revealed that they both have high standards to be achieved and ensure its attainment by using both cognitive and behavioral

The review examines the physicochemical properties, distribution in the environment, the effect on living organisms, including toxicity and ecotoxicity, ways of removing aluminum and its compounds from the human and animal organism. Analysis of scientific literature has shown that the widespread use of aluminum in nature, its use in the agricultural, food, cosmetic, aluminum, oil-producing industries, medicine, water treatment processes and other fields of activity leads to an increased intake of this element into the human body. The cumulative nature of the toxic effect of aluminum and its compounds leads to negative consequences for the respiratory, nervous, musculoskeletal systems, and mammary glands.

Business is an activity that is routinely carried out by many people, one of the promising businesses is a business that provides the needs of electronic goods to meet the needs of daily life, high demand causes business people to be more careful and selective in seeing the pattern of customers who want perform transactions in order to avoid business risks appropriately. Business people use a credit system to increase sales for a long time, but the obstacle that often occurs is that many customers who use credit services often delay payments to make the company's finances unstable so someone needs to predict someone who has the potential to do bad credit for electronic goods. using a system that helps business owners to make it easier to process data and predict patterns of bad credit for electronic goods that have been formed from previous data using the KNN algorithm approach, so that the results show the closeness of the value to the data of old customers, both those who pay properly and those who make payments in default and it can be obtained that the processing process accelerates data processing with precise results in the problem solving process

The Impact

Understanding how people use technology remains important, particularly when measuring the impact this might have on individuals and society. To date, research within psychological science often frames new technology as problematic with overwhelmingly negative consequences. However, this paper argues that the latest generation of psychometric tools, which aim to assess smartphone usage, are unable to capture technology related experiences or behaviors. As a result, many conclusions concerning the psychological impact of technology use remain unsound. Current assessments have also failed to keep pace with new methodological developments and these data-intensive approaches challenge the notion that smartphones and related technologies are inherently problematic. The field should now consider how it might re-position itself conceptually and methodologically given that many ‘addictive’ technologies have long since become intertwined with daily life.

One of the most serious threats to the environment in today’s world is plastic pollution. The reason for widespread of plastic is its poor disposal management, indiscriminate use of plastic and its related products. There was a tremendous increase in the production of plastic from the start of 21st century due to its high demand which tripled the waste in these two decades. This review papers aims at providing the understanding of various techniques used for PET plastic degrading process and currently used in large scale that is quite detrimental to the environment. Further, the recent discovery of the bacteria eating enzyme provided a shaft of light in waste green recycling process. Adding to this, there is an outline provided for bioengineering of the most preferred enzymes for hydrolysis process result is compared that which one is more efficient one. Comparing them and trying to exploring the potential of various mutated enzymes for hydrolyzing of plastic waste formulated by various researchers to identify the Nobel PET catalyst which can solve the massive environment crisis when used in large-scale.

Poor Understanding

For more than a year and a half, the world has been living in the grips of Covid-19, which has had a serious impact on the lifestyle of the people of all countries. From March 2020, the population of most European countries has been forced to revise the existing rules of everyday life and go into a state of siege. This was due to a poor understanding of power and danger of viral infection that most likely came first from China to Europe in the fall of 2019. Italy was one of the first states, which faced all the negative consequences of the pandemia. The first Italian patient was identified in December 2019. The new disease did not cause any particular alarm among doctors, patients, media, and most importantly, the Italian government. As a result in March 2020 Italian medical system, which was not ready for a massive increase of Covid-19 patients, literally collapsed. Article is based on an analysis of the results of the various research, including materials of Rome Institute for Economic and Social Research (Eurispes), forecasts by consulting companies and world statistics. An attempt has been undertaken to show the changes in consumer behavior in Italy and its impact on the daily life of Italians.

Maladaptive Behaviour

Despite its many undoubted advantages, mobile phone use has been associated with harmful and/or maladaptive behaviour. Problematic mobile phone use is considered as an inability of individuals to regulate their use of the mobile phone, and it eventually leads to negative consequences in daily life. The first goal of this article is to define and conceptualize the various facets of dysfunctional mobile phone use. The second goal is to describe the various steps of validating an instrument to assess problematic mobile phone use. Such an instrument needs to (1.) specify the user's mobile phone behaviour (i.e., the applications they use on their mobile phone), (2.) provide accurate measures of actual mobile phone use, and (3.) assess the extent of problematic mobile phone use. A comprehensive review of the existing validated questionnaires is provided. The theoretical and methodological limitations of the existing measures are then discussed.
