ABSTRACT

To achieve carbon emission reduction target (CERT) by 2030 and carbon-neutrality in 2050, it is important to actively reduce the emission gap in the private building sector. However, the ongoing COVID-19 pandemic and the Russian-Ukraine war are threatening the green remodeling policy (GRP) worldwide. Therefore, this study analyzed energy consumption savings, GHG emission reduction, and net present value when applying green remodeling to a private building to predict whether or not the current GRP could achieve 2030 CERT and 2050 carbon-neutrality. The main findings are as follows. First, yearly electricity and gas consumption of 84.97 m2 type households can be reduced by 6.19% and 15.58% through green remodeling. Second, based on the energy saving, yearly GHG emission can be reduced about 0.34tCO2eq. Third, the economic feasibility of green remodeling cannot be achieved via the current policy, and NPV17 decreases up to USD-51,485 depending on the credit loan interest rate and the green remodeling interest subsidy program. In other words, it is difficult to reach 2030 CERT and 2050 carbon-neutrality via the current policy. Therefore, the South Korean government is required to reorganize financial policies, establish active systems, increase public awareness of the policy, and improve energy efficiency technology. © 2023 Elsevier B.V.

ABSTRACT

In this study, it was found that the spillover effects between oil futures markets and commodity futures markets. I use the volatility spillover index of Diebold and Yilmaz (2012) to analyze the connectedness between oil futures and commodity futures returns. The main analysis results of this study are as follows. First, I show that spillover effects depend on the period, and especially find that spillover effects are active after the Russian-Ukraine War. Second, I find that the WTI and BRENT futures have a high value in both to spillover effects and From spillover effects. Third, the wheat futures market plays an important role after the COVID-19 outbreak. Finally, I find that the non-ferrous metal futures market is dependent on other markets in most periods. As a result, I find that the WTI and BRENT futures are important information senders in the oil and product asset markets. And the empirical results show that the Russia-Ukraine war increases the linkage of the futures market rather than COVID-19 outbreak. © 2023, Success Culture Press. All rights reserved.

ABSTRACT

This article examines how flag states, port states, and the shipping industry have attempted to fulfill their obligations to carry out mandatory ship surveys and certification in response to challenges arising from the COVID-19 pandemic and provides guidance for future pandemics. Although the International Maritime Organization (IMO) Conventions do not have procedures to deal with the impacts of global pandemics on ship surveys and certification, the IMO has provided guidance via circular letters, taking a pragmatic and practical approach. Several flag states extended the validity of certificates by taking either a case-by-case or a blanket approach within the statutory maximum of three months. With regard to the extension beyond the statutory period of three months, flag states should consider requests using an evidence-based assessment on a case-by-case basis. Classification societies play an important role in the extension of the validity of certificates by providing their technical expertise and recommendations. Port state control serves as a safety net in the event that flag states do not comply with their obligations. In this regard, cooperation between flag states, port states, and classification societies is key to managing survey and certification during a pandemic. Moreover, the COVID-19 pandemic has demonstrated an accelerated need for the development of remote surveys. It has also illustrated a need to develop guidance on remote surveys under exceptional circumstances in order to respond to future pandemics. © 2023 Taylor & Francis Group, LLC.

ABSTRACT

The paper investigates how parents of American teenagers navigated teen social media use during the early months of the COVID-19 pandemic, amid school closures and stay-at-home orders. Through an online survey, parents of teenagers reported on teen engagement, happiness, and social media use along with their own levels and types of oversight related to that social media use. Findings showed that parents perceived their teens to be similarly or less engaged in school and social activities than usual, and generally happy with social media use contributing somewhat to that happiness. Parental monitoring of social media use was the same or lower than during pre-pandemic times overall, with some significant differences related to parent gender, teen age, and teen gender. © 2022 IADIS Press.

ABSTRACT

This article examines the impact of COVID-19 on the international regulation of merchant shipping. First, it provides an overview of the international regulatory framework established by the WHO, IMO and ILO to respond to the impact of global health emergencies on international merchant shipping. It then examines the responses of these organisations and the shipping industry to the impact of the COVID-19 pandemic on merchant shipping. The COVID-19 pandemic has demonstrated that global health emergencies require enhanced preparedness and response planning and cooperation between the IMO, WHO and ILO, which includes consultation and cooperation with global shipping associations and seafarers' unions. The objective of the preparedness and response planning should be to keep maritime supply chains open while preventing the spread of infectious disease from ship-to-ship, ship-to-shore or shore-to-ship. Equally important, the enhanced cooperation at the global level must be matched by enhanced inter-agency cooperation at the national level. © 2022 Koninklijke Brill NV.

ABSTRACT

During Summer 2020, the COVID-19 pandemic limited people's contact with others outside of their households. Teenagers experienced a great deal of disruption to their lives and found themselves reliant on their phones and social media to occupy their time and maintain peer connections. In this study, we examine the activities of 43 teens in the United States. Teens were interviewed twice and kept week-long video diaries documenting their daily online and offline activities. Findings show that social media activities were critical for maintaining friendships and provided a sense of virtual independence during quarantine. Teens also pursued independent informal learning activities via social media. However, themes of shame also arose, with teens internalizing negative messages from parents and media about social media use. © 14th International Conference on ICT, Society, and Human Beings, ICT 2021, 18th International Conference on Web Based Communities and Social Media, WBC 2021 and 13th International Conference on e-Health, EH 2021 - Held at the 15th Multi-Conference on Computer Science and Information Systems, MCCSIS 2021.

ABSTRACT

Background: This study aimed to investigate psychological distress among infectious disease (ID) physicians during the coronavirus disease (COVID-19) outbreak in the Republic of Korea. Methods: Using an online-based survey link sent via text message and email, we conducted a survey from April 21 to 25, 2020, targeting all ID physicians currently working in ID (n = 265). The questionnaire was based on the Maslach Burnout Inventory-Human Services Survey and the Depression, Anxiety, and Stress Scales, and information was collected on factors protecting against psychological distress and difficulties in relation to COVID-19. Results: Of 265 ID physicians, 115 (43.3%) responded, showing burnout (97, 90.4%), depression (20, 17.4%), anxiety (23, 20.0%), and stress (5, 4.3%). There were no differences in terms of distress between ID physicians who were directly involved in the care of patients with COVID-19 or not (Table 1). Greater than 50% of physicians valued their work and felt recognized by others, whereas < 10% indicated that sufficient human and financial support and private time had been provided during the outbreak. The most challenging issues concerned a lack of human resources for COVID-19 treatment or infection control, a shortage of personal protective equipment or airborne infection isolation rooms, pressure for research, and lack of guidelines for COVID-19 management (Figure 1). Conclusion: During the COVID-19 outbreak in the ROK, most respondents reported psychological distress. Preparing strategies for infectious disease outbreaks that support ID physicians is essential.

ABSTRACT

Diarrhea is the most common cause of death in calves, and remains a major health challenge. Although there are many studies on the related pathogens, the understanding of the clinicopathological changes is limited. This study aimed to identify the pathogens and observe the clinicopathological changes in electrolytes and acute phase proteins (APPs) associated with diarrhea. Blood samples and fecal samples were collected from 141 calves for the determination of APPs, electrolyte and acid-base status and identification of enteropathogens, respectively. Single or co-infections with enteropathogens, including virus (bovine viral diarrhea virus, coronavirus, and rotavirus), Eimeria, Cryptosporidium, and Escherichia coli K99 were detected in both non-diarrheic and diarrheic calves. Levels of APPs such as serum amyloid A, haptoglobin and fibrinogen were comparable between diarrheic and non-diarrheic calves. Hypoglycemia, high blood urea, electrolytes and acid-base imbalance (hyponatremia, hypochloremia, and decreased bicarbonate), and strong ion difference (SID) acidosis showed a significant association in diarrheic calves (p < 0.01). Particularly, significant hyponatremia, bicarbonate loss, SID acidosis, hypoglycemia, and elevated blood urea nitrogen were found in rotavirus-infected calves. Monitoring the clinicopathological parameters of APPs and electrolyte levels could be vital in the clinical management of diarrheic calves. © 2020 Korean Society of Veterinary Science.
