The Tryptophan-Kynurenine Metabolic Pathway
Tryptophan (TRP) is one of the essential amino acids, which participates in protein synthesis. The tryptophan’s main metabolic route is the kynurenine pathway (KP) through which approximately 90-95% of TRP degrades into nicotinamide adenine dinucleotide (NAD+) and other bioactive metabolites. The appropriate amount of NAD+ is essential to maintain the operation and the viability of cells. The other molecules are neurotoxic, neuroprotective, oxidant, antioxidant, and/or immune modifiers. They play an important role in the function of the brain and the peripheral tissues. The change in the levels of the bioactive molecules is considered to contribute to the development of a wide range of illnesses from cancer to immunologic, neurodegenerative, and psychiatric diseases.

Causalities of Upscaled Urban Aquaponics
Aquaponics, the water-reusing production of fish and crops, is taken as an example to investigate the consequences of upscaling a nature-based solution in a circular city. We developed an upscaled-aquaponic scenario for the German metropolis of Berlin, analysed the impacts, and studied the system dynamics. To meet the annual fish, tomato, and lettuce demand of Berlin’s 3.77 million residents would require approximately 370 aquaponic facilities covering a total area of 224 hectares and the use of different combinations of fish and crops: catfish/tomato (56%), catfish/lettuce (13%), and tilapia/tomato (31%). As a predominant effect, in terms of water, aquaponic production would save about 2.0 million m3 of water compared to the baseline. On the supply-side, we identified significant causal link chains concerning the Food-Water-Energy nexus at the aquaponic facility level as well as causal relations of a production relocation to Berlin. On the demand-side, a ‘freshwater pescatarian diet’ is discussed. The new and comprehensive findings at different system levels require further investigations on this topic. Upscaled aquaponics can produce a relevant contribution to Berlin’s sustainability and to implement it, research is needed to find suitable sites for local aquaponics in Berlin, possibly inside buildings, on urban roofscape, or in peri-urban areas.

Korea Green New Deal
Various developed nations, including the US (February 2019) and the EU (December 2019), have recently relaunched Green New Deals similar to the climate-oriented economic stimulus policies implemented after the 2008–2009 Great Recession; such green stimulus packages not only raise investments with short-term benefits for economic output and jobs, but also lay the groundwork for long-term innovation and economic development aligned with environmental constraints. The Korean government also considered reintroducing the Korean Green Growth Initiative of 2009 in response to the COVID-19 crisis as a national industrial strategy to promote green innovation and transform the industrial structure of key global industries such as motor vehicles, batteries, and electricity distribution systems; the aim was to make Korea a competitive leader in the future global economic structure. Eventually, the Korean government announced the Green New Deal as one of the three pillars of the Korean New Deal on 14 July 2020, and proposed a total investment of KRW 73.4 trillion (KRW 42.7 trillion from the treasury) over the next five years.

Sustainability Development in Educational Institutions
Sustainable development (SD) addresses the biggest challenges facing humanity in the 21st century. Public sector organizations, primarily higher education institutions (HEIs), are facing greater levels of responsibility since adopting and committing to the Agenda 2030 for Sustainable Development (SD) and its 17 Sustainable Development Goals (SDGs). HEIs are expected to provide guidance for various stakeholders on this matter, but also to implement this agenda and the SDGs in their institutions.

E-Government Service
Electronic government serves to connect activities between society and the government. People are familiar with the term electronic government and have used other government applications to support their activities, such as searching for regional information, tourism potential, e-filing, and electronic citizen cards. The evolution of electronic government is occurring very quickly to facilitate the complex problems faced today and prepare for changes in the future. The role of government cannot be separated from service activities to the general citizen. One of the digital channels is electronic government, that can be used as a two-way service media that can adapt to changes both technically, as well as in design and strategy. Electronic government quality is an important domain that can influence citizens’ responses to the quality of facilities provided by the government. Connection quality is a user’s concept of what is felt that affects the quality of credence and contentment to the perceived experience.

Household Food Waste in Bangkok
Food waste (FW) is one of the world’s major crises in both developed and developing countries. Up to 1.3 billion tons of food across the globe is thrown away each year, accounting for one third of all food produced for human consumption and presenting tremendous social, economic, and environmental challenges. In Thailand, FW causes a significant problem when it comes to waste management, particularly in metropolitan areas. Studies conducted between 2005 and 2009 indicated that FW made up the greatest proportion of all waste collected in Bangkok at between 42% and 45%. This waste was generated in households and was usually thrown away into garbage bins, to be collected and buried in landfills by governmental and private sector companies.

Business Simulation Games Analysis
The search for the best academic training of its students, increasingly aligned with the needs of organizations, has led educational institutions to use support tools in the development and improvement of knowledge, skills, and competencies. Therefore, technology in education is becoming increasingly relevant, and many institutions have been increasing their virtual education strategies due to the COVID-19 pandemic. Thus, the importance of a deeper scientific look at the possible contributions of the Business Simulation Games (BSG) emerges. The few types of research related to the design of BSG, mainly associated with the user experience, point out the need for contributions from other studies. In this sense, the approximation results from investigations with Serious Games can provide relevant insights into the theme. They are active learning tools that present similar didactic principles of demonstrative, activity, accessibility, a combination of theory and practice, scientific character, and involvement, to develop skills and knowledge for its users.

Information Asymmetry Mitigators
The research aims to identify indicators of representative information on sustainability from the cooperative organizations’ primary stakeholders’ perspective to mitigate information asymmetry. The study develops in seven stages: the primary stakeholders’ selection and training; the evidence survey; the triangulation between stakeholder responses, forming an indicators list; the indicators analysis by specialists; tests for indicators disclosure; and the indicators validation through the disclosure analysis. As a result, a list contains 61 sustainability indicators from the primary stakeholders’ perspective, in four pillars: economic, 20; social, 18; environmental, 13; and cultural, 10. With the cooperative organizations’ websites disclosure analysis, we found that the disclosure policies focus more on information asymmetry mitigating in the pillars: cultural and social, with the environmental and economic being neglected. Therefore, the procedures for disclosing information on sustainability have weaknesses. These policies reduce the primary stakeholders’ reliability about the cooperatives management system respective, limiting the primary stakeholders’ perspective on the cooperative organization value.
