Book chapter Effects of COVID-19: An Environmental Point of View The emergence of SARS-CoV-2 (ß-coronavirus) in Wuhan, China, in late December 2019 has created unprecedented devastating effects on social, economic, public health, and global environmental status with an alarming spike in mortality and morbidity. Preventive measures targeted at reducing and preventing the communal transmission of the virus varied from travel restrictions, contact tracing, social distancing etiquettes, good hygiene and ethanol sterilizer usage, face masks, and performance of massive COVID-19 screening tests. These practices indicate that priority has been solely hinged on public health safety, but little is being done on important environmental implications of the virus. It is highly likely that some countries may forgo sustainable environmental impact assessment of the virus but focus on pursuing rapid economic growth of the nations. However, it is logical to state that an improvement of environmental quality and climate systems would generate a consequential improvement in the economy and hence the health and well-being of citizens. The environmental impact of COVID-19 offers direct and indirect benefits/disadvantages to public health, economy, and sociocultural development of people. One of the response methodologies currently being practiced all over the world is partial/total lockdown, which has generated a reduction in carbon footprint in terms of greenhouse gas (GHG) emissions from manufacturing industries, smoke emission from oil and its products’ usage, and an obvious decline in nitrogen oxide (NO2) concentration in European countries such as France, Germany, Spain, and Italy, as a result of reduction in anthropogenic-based activities. Beaches and recreational centers have been deserted, indicating a reduction in waste load generated by tourists and a significant noise reduction due to non-patronage of mass transit/public transportation systems, which may increase transmission risk of COVID-19. Gradual ease of lockdown protocols required some firms to institute COVID-19 work ethics - one of which requires the repeal of disposable bags and containers, while embracing single-use packaging and online ordering of necessities in order to reduce virus transmission. As much as this offers a preventive approach of the virus transmission and infection, it however poses a negative effect on the environment because recycling programs have been reportedly suspended in many countries and sustainable waste management is greatly inhibited. Further, plastic pollution of waterways was recorded in China where plastic-made medical masks (made of polypropylene) were collected from the sea by some environmentalists and concluded that COVID-19 measures created a surge in water pollution indices. The study aimed at analyzing the myriad effects of COVID-19 on environmental parameters by evaluating the current global status of COVID-19 and also proffering well-informed and sustainable solutions to assess the environmental effects of the pandemic. © 2021 WILEY-VCH GmbH, Boschstr. 12, 69469 Weinheim, Germany.

Article Effects of edible coatings with various natural browning inhibitors on the qualitative characteristics of banana (Musa acuminata Cavendish Subgroup) during storage Bananas (Musa acuminata Cavendish Subgroup) have a short shelf-life due to surface browning. This study aimed to select the best edible coating agent including a natural browning inhibitor (green tea, Rhus chinensis, rice bran and Morus alba root extracts) that can extend the shelf-life of bananas. Bananas were coated with 1.5% carboxymethyl cellulose and 2.0% Tween 80 (CM), CM and 1.5% green tea extract, CM and 1.5% Rhus chinensis extract, CM and rice bran extract, and CM and 1.5% Morus alba extract (CM-M). An uncoated sample was used as the control. The weight loss, firmness, polyphenol oxidase (PPO) activity, browning index (BI), total chlorophyll content, and color of the coated bananas during storage were evaluated. Treatment with CM-M exhibited lesser changes in the weight and firmness of bananas during storage, compared with the other treatments. Moreover, CM-M delayed the enzymatic browning of bananas during storage, maintained the PPO activity, and showed the lowest BI, compared with other treatments. The changes in the total chlorophyll content and color (ΔE value) were lower in the CM-M coated samples than in the control samples. The CM-M coated samples showed decreases in the total chlorophyll content and ΔE value compared with that noted in bananas with the other coatings. Therefore, our findings indicated Morus alba root extract supplementation to be the most suitable edible coating agent, which maintains the quality and appearance of bananas during storage. © 2020 The Korean Society of Food Preservation.

Article Effects of elevated atmospheric CO2 on rhizosphere microbial community of Pinus densiflora (Korean red pine) The concentration of atmospheric CO2 is increasing largely owing to human activities. Although it is well established that elevated CO2 (eCO(2)) stimulates plant growth and primary productivity, the effect of eCO(2) on soil microbial communities remains poorly understood. In this study, we aimed to examine the effects of eCO(2) on the taxonomical diversity, composition, and structure of rhizosphere microbial communities of Korean red pine (Pinus densiflora) through next-generation sequencing (NGS) of 16S rRNA genes. Three bacterial phyla, Proteobacteria, Acidobacteria, and Actinobacteria, were found to be dominant in all samples. Species richness estimates (Chao1 and ACE) and diversity indices (Shannon and Simpson) for the three sampling chambers were the highest from the eCO(2) (approximately 1.4x ambient, approximate to 560ppm). These findings suggested that elevated atmospheric CO2 affected the bacterial community composition in the rhizosphere of Korean red pine (Pinus densiflora).

Article Effects of Form-Function Incongruities on Consumers' Preference Background Consumers fundamentally depend on visual cues to evaluate and compare various products. One common strategy for designers or marketers attempting to distinguish their products from others is to use product design with form-function incongruity. The current research aims to present systematic studies exploring whether and how the level of form-function incongruity (low vs. high) affects customers' preference. Methods To test our predictions, we conducted Study 1 by recruiting 87 undergraduate students in South Korea using actual product (highlight pen) in the market. Then, we conducted an online survey (Study 2) with 115 participants to explore the mechanism of the effects of formfunction incongruity on product preference and we confirmed the validity of the results of Study 1. Results This research provides evidence that a high-level of form-function incongruity could be more attractive under a condition in which the options are presented separately. The effects of form-function incongruity on product preference was mediated by perceived hedonic benefit. We also verified that while the results of studies revealed preference-reversal phenomena in choice condition, this preference-reversal phenomenon could be mitigated by a gift-giving condition (vs. control). Conclusions This research provides empirical evidence on consumers' preference of products with form-function incongruity, and the mechanism and the boundary condition of form-function incongruity effects. Based on our research, we provide insights into designers and marketers who aim to use form-function incongruity to differentiate and evaluate their products more favorably. © 2021.

Article Effects of gelling agents and sugar substitutes on the quality characteristics of carrot jelly In this study, the quality characteristics of carrot jellies prepared using different gelling agents (gelatin and carrageenan) and sugar substitutes (sucrose, sorbitol, and xylitol) were evaluated. The effects of gelling agents and sugar substitutes on the pH, °Brix, color, syneresis, melting-down rate, textural properties, and sensory acceptance of the jellies were determined. Textural analysis indicated that gelatin-based jellies containing sugar substitutes sorbitol and xylitol showed higher hardness than that of gelatin-based jelly containing sucrose. Among all samples, jellies containing 1.5% (w/v) carrageenan showed higher hardness, cohesiveness, and chewiness than those of other jellies, regardless of the sugar substitute. The pH and °Brix of carrageenan-based jellies were lower than those of gelatin-based jellies. The instrumental color values of jellies containing gelatin decreased with an increase in gelatin concentration. Gelatin-based jellies (3 and 5 %) containing sucrose and gelatin-based jelly (5%) containing xylitol showed lower syneresis than that in other jellies. Jelly containing 5% gelatin content had a lower melting-down rate compared with that containing 3% gelatin content. Moreover, carrageenan-based jellies showed a lower melting-down rate than that of gelatin-based jellies Carrot jellies containing 3% gelatin and xylitol showed a high score for sensory acceptance. Based on the results, the utilization of 3% gelatin and xylitol as a sugar substitute is suitable for producing carrot jellies showing high sensory preference and stability.

Article Effects of handoff education using concept mapping and PASS-BAR Purpose: The purpose of this study was to identify effects of Handoff Education using Concept mapping and PASS-BAR (HECPAR) on clinical reasoning competence, self-efficacy for handoff, and handoff performance of new nurses. Methods: Participants were randomly allocated into an experimental group (n=20) and control group (n=21). The experimental group received HECPAR which consisted of a one hour lecture, case based clinical practicum, and mentoring for a week. The control group received the usual informal handoffs education from senior nurses. Clinical reasoning competence, self-efficacy for handoff, and handoff performance were measured before and a week after HECPAR. Data were analyzed using Mann-Whitney U test, independent t-test, Fisher's exact test, and chi-sqaure test. Results: The experimental group showed significant improvement in clinical reasoning competence (z=-2.29, p=.022), handoff performance (z=-2.23, p=.026), and self-efficacy of handoff (t=3.47, p=.001) compared to the control group. Conclusion: The results indicate that HECPAR is effective in improving clinical reasoning competence, self-efficacy for handoff, and handoff performance by new nurses. In addition, integrating concept mapping, PASS-BAR, and mentoring proved beneficial for handoff education for new nurses. © 2021 American Association for the Advancement of Science.

Article Effects of hydrotherapy on muscle damage and recovery profile after eccentric exercise in arm PURPOSE: This study aimed to examine the effect of hydrotherapy at different temperatures following eccentric exercise on muscle damage and recovery profiles in young men. METHODS: Male college students without any cardiovascular or orthopedic disorders were randomly assigned to three hydrotherapy groups: a 5°C group (cold water, COLD), a 15°C group (cool water, COOL), and a control group (CON).Thirty maximal eccentric exercises were performed using the participants’ nondominant elbow flexor muscles. Each treatment consisted of immersion five times for 1 minute, along with a 1-minute rest between each immersion trial. Each intervention was conducted immediately after the eccentric exercise and every 24 hours. Changes in the level of exercise-induced muscle damage (EIMD), circumference, muscle soreness, range of motion (ROM), maximum voluntary isometric contraction (MVIC), muscle dynamic stiffness, and muscular echo intensity (EI) were measured.All parameters were measured at 24, 48, 72, and 96 hours after exercise, as well as immediately before and after exercise. RESULTS: Muscle soreness was significantly higher in the COLD group than in the other groups. Moreover, the muscle circumference tended to increase in the COLD group than in the other groups. However, an increase in the dynamic stiffness and EI, promoting the recovery of MVIC, was observed in the COOL group. In addition, ROM tended to return more rapidly in the COOL group than in the other groups. CONCLUSIONS: This study suggests that hydrotherapy at moderately low temperatures compared with that at extremely low temperatures may induce relatively positive effects on EIMD and recovery phases following eccentric exercise in the arms. © 2021 Korean Society of Exercise Physiology.

Article Effects of Organic Fertilizer Mixed with Food Waste Dry Powder on the Growth of Chinese Cabbage Seedlings Food waste is a common global threat to the environment, agriculture, and society. In the present study, we used 30% food waste, mixed with 70% bio-fertilizers, and evaluated their ability to affect the growth of Chinese cabbage. The experiment was conducted using different concentrations of food waste to investigate their effect on Chinese cabbage growth, chlorophyll content, and mineral content. Leaf length, root length, and fresh and dry weight were significantly increased in plants treated with control fertilizer (CF) and fertilizer mixed with food waste (MF). However, high concentrations of food waste decreased the growth and biomass of Chinese cabbage due to salt content. Furthermore, higher chlorophyll content, transpiration efficiency, and photosynthetic rate were observed in CF- and MF-treated plants, while higher chlorophyll fluorescence was observed in the MF x 2 and MF x 6 treatments. Inductively coupled plasm mass spectrometry (ICP-MS) results showed an increase in potassium (K), calcium (Ca), phosphorous (P), and magnesium (Mg) contents in the MF and MF x 2 treatments, while higher sodium (Na) content was observed in the MF x 4 and MF x 6 treatments due to the high salt content found in food waste. The analysis of abscisic acid (ABA) showed that increasing amounts of food waste increase the endogenous ABA content, compromising the survival of plants. In conclusion, optimal amounts of food waste-up to MF and MF x 2-increase plant growth and provide an ecofriendly approach to be employed in the agriculture production system.

Article Effects of Self-Education on Patient Safety via Smartphone Application for Self-Efficacy and Safety Behaviors of Inpatients in Korea Objectives: This study aimed to determine whether self-educational intervention on patient safety via a smartphone application could improve the level of self-efficacy and safety behaviors of patients. In addition the effect of change in self-efficacy on the improvement of safety behaviors after self-educational intervention was investigated. Methods: A one-group pre- and post-test design and convenience sampling were implemented. Self-educational intervention via smartphone application was provided to 94 participants in a tertiary university hospital in South Korea. The smartphone application included learning contents on why the participation of patients is critical in preventing hospital-acquired infections and surgery-related adverse events during hospitalization. Paired t-tests and hierarchical regression analysis were conducted to assess the effect of self-educational intervention and self-efficacy on the improvement of safety behaviors of patients. Results: After the intervention, the level of self-efficacy and safety behaviors significantly increased from 2.53 to 2.95 and from 2.00 to 2.62, respectively. In the hierarchical regression analysis, the change in self-efficacy accounted for 35.4% of the variance in the improvement of safety behaviors. Conclusions: The results of this study demonstrated that self-education on patient safety via a smartphone application was an effective strategy to enhance patients' self-efficacy and safety behaviors. This process could ultimately enhance patient safety by promoting patient involvement during hospitalization and preventing the occurrence of medical errors.

Article Effects of smart-care services program for breast cancer survivors Purpose: The purpose of this study was to examine the effects of a smart-care services program for breast cancer survivors on cognitive function and physical health. Methods: A quasi-experimental control group pretest posttest design was used. Subjects were recruited in D city, and data were collected from July 2017 to February 2018. The experimental group (n=24) participated in the smart-care services program, whereas the control group (n=26) received conventional management. The smart-care services program consisted of addressing cognitive function problems arising from chemotherapy, diet, exercise, head/neck massage and self-monitoring using smartphone applications and smart bands. All participants underwent assessments at baseline, at 6 weeks, and at 12 weeks. Data were analyzed using descriptive statistics (frequency, percentage, mean and standard deviation), a chi-squared test, t-test, and repeated measures ANOVA. Results: After the smart-care services program, significant differences were found between the groups in cognitive function (F=18.91, p<.001) and sleep time (F=9.25, p<.001). No significant differences were found between the groups in caloric consumption after the program. Conclusion: The smart-care services program significantly improved the level of cognitive function and sleep time for breast cancer survivors. The use of this smart-care services program for breast cancer survivors might be an effective nursing intervention tool for improving cognitive function and health behaviors.

Article Effects of synthesis method, melamine content and GPC parameter on the molecular weight of melamine-urea-formaldehyde resins This study was conducted to investigate the effects of the synthesis method, melamine content, and GPC parameters (such as flow rate, column-detector temperature, and sample injection temperature) on the molecular weight of melamine– urea–formaldehyde (MUF) resins. Two different synthesis methods were employed. In the first method, MUF-A resins were synthesized by simultaneously reacting urea, formaldehyde, and melamine (5%, 10%, and 20%) using the reaction of alkaline–acid–alkaline steps under controlled temperature and viscosity. In the second method, MUF-B resins were synthesized by first reacting melamine at the same levels with formaldehyde and then by adding urea. The highest weight average molecular weight (Mw) of MUF-A resins was found at 10% melamine content when the flow rate was 0.3 and 0.8 ml/min; Mw decreased slightly at 20% melamine content. The results showed that Mw increased with an increase in the melamine content when the flow rate was 0.5 and 1.0 ml/min. In addition, Mw was the highest when the flow rate, column-detector temperature, and injection temperature were 0.3 ml/min, 50°C, and 25°C, respectively. On the contrary, MUF-B resins had greater Mw and number average molecular weight (Mn) than MUF-A resins. Overall, Mw and Mn increased as the melamine content increased. The optimal GPC parameter for MUF resins was determined as follows: a flow rate of 0.5 ml/min, a column-detector temperature of 50°C, and a sample injection temperature of 50°C. © 2021, Korean Society of Wood Science Technology.

Article Effects of transdermal methylsulfonylmethane on muscle damage and recovery following eccentric exercise PURPOSE: The present study aimed to investigate the effects of transdermal application of methylsulfonylmethane (MSM) on muscle damage and recovery following eccentric exercise in young men. METHODS: Eleven college-aged men without any cardiovascular or orthopedic disorders underwent two sessions consisting of a control session (CS) and an experimental session (ES) in a random order with at least 2 weeks of wash-out between the sessions. The participants performed 30 maximal eccentric exercises involving their non-dominant elbow flexors in each session. Circumference, muscle soreness, range of motion, maximal voluntary isometric contraction (MVIC), and muscular echo intensity (EI) were measured to evaluate the changes in the level of exercise-induced muscle damage (EIMD). All measurements were performed at 24, 48, 72, and 96 hours after exercise and also immediately before and after exercise. RESULTS: Transdermal application of MSM in ES attenuated muscle swelling and decreased MVIC after eccentric exercise when compared with CS. Muscle soreness and EI tended to increase less rapidly and decrease more rapidly in ES than in CS.

Article Effects of transformational leadership on teachers’ self-efficacy in education for sustainable development: A serial mediation analysis Based on empirical evidence, this study aimed to analyze the effect of transformational leadership on teachers' self-efficacy in ESD and test mediation effects in the relationship between transformational leadership and teachers' self-efficacy in ESD. To this end, researchers constructed nine hypotheses, predicting direct effects among variables, each single mediation effect of two mediators, and serial multiple mediation effect. The participants of the research consisted of 193 Korean in-service teachers. Data analysis was conducted using descriptive statistics, the Pearson correlation coefficient, and multiple regression analysis. In addition, researchers applied serial mediation procedures with PROCESS Macro for SPSS to test specific mediate effects based on the bootstrap method. The the research, there were identified mechanisms through which the influence of the principal's transformational leadership on teachers' efficacy occurs in the context of ESD. The findings of the study were discussed in the light of relevant literature, and some suggestions were made for the future. ©2021 Birlesik Dunya Yenilik Arastirma ve Yayincilik Merkezi.

Article Effects of working fluids on spray modes and atomization characteristics in electrospray; [정전분무의 작동유체가 분무 형상 및 미립화 특성에 미치는 영향] An electrospray is widely used in the industry due to uniform and continuous droplet generation. Most of the studies on the electrospray modes are conducted in the cone jet mode. The goal of this study is to confirm the spray patterns for each mode of the electrospray by setting various conditions, such as nozzle to substrate, nozzle diameters, fluid properties (Viscosity and Conductivity), and flow rate. As a result, 7 modes were observed by the applied voltage and flow rate. It was confirmed that the smallest droplet size was produced in the cone jet mode and working fluid V (High Conductivity).

Article Efficacy and safety of a switch from twicedaily tacrolimus to once-daily generic tacrolimus in stable liver transplant patients Background: Once-daily tacrolimus reduces non-compliance relative to twice-daily tacrolimus. However, little is known about the safety and efficacy of conversion from twice-daily tacrolimus to generic once-daily tacrolimus in liver transplantation (LT). Herein, we investigated the efficacy and safety of a switch from twice-daily tacrolimus to generic once-daily tacrolimus in patients with stable liver graft function. Methods: This prospective, multicenter, open-label, single-arm study was conducted in 17 medical centers for 1 year from July 2019 to July 2020 (NCT04069065). Primary endpoint was the incidence of biopsy-proven acute rejection (BPAR) for 24 weeks after conversion. Secondary endpoints were graft failure, patient death, and adverse events (AEs). Results: Of 151 screened LT patients, 144 patients were enrolled. BPAR, graft failure, and patient death did not occur in this patient population. There were no statistical differences in blood tests, liver function tests, or biochemical tests between visits in any of the patients. Median tacrolimus trough level decreased abruptly from 4.7 ng/mL to 3.2 ng/mL after generic once-daily tacrolimus conversion, but median tacrolimus dose increased due to low tacrolimus trough level. Ninety-two adverse events occurred in 54 patients. Liver enzyme levels increased in seven patients (4.9%) after the switch to generic once-daily tacrolimus, but the liver function tests of these patients normalized thereafter. There were three cases of severe AEs not related to investigational drug. Conclusions: Present study suggests that conversion from twice-daily tacrolimus to generic once-daily tacrolimus is effective and safe in stable LT patients. © 2021 Korean Journal of Transplantation.
