Rupture Directivity of the 2021 ML 2.2 Gwangyang, Korea, Microearthquake: Toward Resolving High-Resolution Rupture Process of a Small Earthquake
Authors: Seo Min-Seong , Kim Won-Young , Kim YoungHee
Published: November 2022

Moderate-to-large earthquakes (M>6) frequently show clear rupture directivity. Recent studies revealed that a substantial percentage of small-sized earthquakes (M<∼5) display rupture directivity as well, owing to enhanced seismic monitoring. Is rupture directivity a common feature for earthquakes of all sizes? In this study, we investigated the rupture directivity of the 27 August 2021 ML 2.2 Gwangyang microearthquake that occurred at the southern tip of the Korean Peninsula by utilizing data from a recently expanded dense seismic network. The mainshock had two foreshocks and three aftershocks, which enabled us to define the fault plane from precise relative event locations and a well-constrained focal mechanism. Analysis of apparent source time functions obtained with the empirical Green’s function technique reveals that the mainshock ruptured unilaterally toward the east. A detailed analysis of the source pulse leaving the focal sphere in 3D indicates that rupture directivity is consistent with the fault geometry and slip direction. Our study demonstrates that we can resolve rupture directivity of unilaterally rupturing microearthquakes (M<∼3) given adequate azimuthal coverage, and that this will lead to an improved understanding of the seismogenic processes in regions of low seismicity worldwide.

Published: November 2022

Biofabrication approaches, such as three-dimensional (3D) bioprinting of hydrogels, have recently garnered increasing attention, especially in the construction of 3D structures that mimic the complexity of tissues and organs with the capacity for cytocompatibility and post-printing cellular development. However, some printed gels show poor stability and maintain less shape fidelity if parameters such as polymer nature, viscosity, shear-thinning behavior, and crosslinking are affected. Therefore, researchers have incorporated various nanomaterials as bioactive fillers into polymeric hydrogels to address these limitations. Carbon-family nanomaterials (CFNs), hydroxyapatites, nanosilicates, and strontium carbonates have been incorporated into printed gels for application in various biomedical fields. In this review, following the compilation of research publications on CFNs-containing printable gels in various tissue engineering applications, we discuss the types of bioprinters, the prerequisites of bioink and biomaterial ink, as well as the progress and challenges of CFNs-containing printable gels in this field.
El rol del COFECYT en la federalización de la ciencia y la tecnología en Argentina
Authors: Carro Ana Clara
Published: November 2022

El presente artículo describe y analiza el proceso de federalización de la ciencia y la tecnología llevado adelante desde el Consejo Federal de Ciencia y Tecnología (COFECYT). Se define a la federalización como el proceso de descentralizar decisiones y desconcentrar recursos. Para el primer aspecto se analizan los cambios acontecidos en la estructura y procedimientos para la toma de decisiones; para el segundo se realiza un análisis de estadísticas descriptivas de los proyectos financiados en las diferentes convocatorias. Así, por un lado, se observó que, desde su origen el COFECYT se orientó a la solución de problemas socio-productivos, promoviendo el diálogo de actores en territorio, un aspecto alineado con los procesos de federalización. Por otro lado, la decisión de distribuir la misma cantidad de recursos a cada provincia, si bien habilitó la toma de decisiones en cada territorio, adeuda la discusión y elección de criterios verdaderamente equitativos para la desconcentración de recursos.

Oranges are a type of fruit that contains lots of vitamin C and fiber. One of the citrus producing places in Malang is Dusun Precet, which is part of Sumbersekar Village. The abundant citrus plantation products in Precet Hamlet have not been further processed by the residents, so the price falls during the harvest season. Farmers left some of it to rot in the garden, because the cost of picking during the harvest season is more expensive than the selling prices. Whereas the oranges can have a higher selling value if it is processed into orange juice products. The Asset-Based Community Development (ABCD) strategy was implemented by the UIN Maulana Malik Ibrahim Malang team in the form of training activities for processing orange juice products. The basic mindset in ABCD theory on assisted objects has five key steps, namely discovery, dream, design, define, and destiny. Assets that support the ABCD theory in assisted objects are categorized into four, namely human assets, natural assets, economic assets, and social assets. Dusun Hamlet is potential place to process citrus fruits becomes fresh orange juice that can be consumed by the wider community.

Authors: Kim Yoonseob , Kim Tae Ah , Hahn Hyung Min , Kang Byung Hee
Published: November 2022

Delayed closure of an open abdomen (OA) is a clinically challenging task despite its various modalities. It is substantially more difficult when the duration of OA treatment is prolonged due to a patient’s condition. We introduced the management of a patient who had a delayed OA treatment spanning approximately 3 months due to severe abdominal contamination. The 64-year-old male patient had an injured pelvis pressed by a road roller. After visiting a trauma center, the patient initially underwent damage control surgery and OA management; however, early primary abdominal closure failed due to severe peritonitis. After negative pressure wound therapy for several months, an acellular dermal matrix graft followed by a skin graft were successfully used as treatments. A combination of acellular dermal matrix graft, negative pressure wound therapy, and skin graft techniques is a considerable management sequence for patients subjected to delayed OA treatment.

Background: The duration of the vaccine's protective efficacy against SARS-CoV-2 is unknown. Evaluation of the clinical performance of available tests is required. Objectives: To evaluate the clinical performance of three immunoassays for the detection of IgG antibodies generated by mRNA vaccines against SARS-CoV-2. Methods: Two automated immunoassays (Euroimmun Anti-SARS-CoV-2 ELISA IgG and Abbott SARS-CoV-2 CLIA IgG) and one lateral flow immunoassay (LFIA Test Livzon IgG) were tested. 300 samples distributed in 3 groups were analyzed: 100 subjects over 18 years old and under 45 years old, 100 subjects between 45-65 years old and another 100 over 65 years old. collected before vaccination, at 21 days, 1, 2, 3 and 6 months post-vaccination. Sensitivity, specificity, positive predictive value, negative predictive value, positive likelihood ratio, negative likelihood ratio, and agreement (I. Kappa) were calculated for each serological test. Results: Maximum sensitivity for IgG was 98.7%, 98.1%, and 97.8% for the ELISA Euroimmun, CLIA Abbott, and Livzon LFIA assays and maximum specificity for IgG was 99.4%, 99.9%. % and 98.4% ELISA, CLIA and LFIA respectively at 3 months after vaccination with a decrease in antibody levels from the sixth month. The best agreement was observed between ELISA and CLIA 100%; (k = 1.00). The agreement between ELIA, CLIA and LIFIA was 99% (k = 0964) at the second and third month after vaccination. Seroconversion was faster and longer lasting in the younger age groups. Conclusion: Our study showed an equivalent and homogeneous clinical performance for IgG of three immunoassays after vaccination and that the LIFIA assay is the most cost-effective, reliable and accurate for routine use in population studies of seroconversion and seroprevalence.

Published: November 2022

Despite the availability of effective vaccines that lower mortality and morbidity associated with COVID-19, many countries including Italy adopted strict vaccination policies and mandates to increase the uptake of the COVID-19 vaccine. Such mandates have sparked debates on the freedom to choose whether or not to get vaccinated. In this study, we examined the people’s belief in vaccine choice as a predictor of willingness to get vaccinated among a sample of unvaccinated individuals in Italy. An online cross-sectional survey was conducted in Italy in May 2021. The survey collected data on respondents’ demographics and region of residence, socioeconomic factors, belief in the freedom to choose to be vaccinated or not, risk perception of contracting and transmitting the disease, previous vaccine refusal, opinion on adequacy of government measures to address the pandemic, experience in requesting and being denied government aid during the pandemic, and intent to accept COVID-19 vaccination. The analysis employed binary logistic regression models using a hierarchical model building approach to assess the association between intent to accept vaccination and belief in the freedom to choose to vaccinate, while adjusting for other variables of interest. 984 unvaccinated individuals were included in the study. Respondents who agreed that people should be free to decide whether or not to vaccinate with no restrictions on their personal life had 85% lower odds of vaccine acceptance (OR=0.15 ;95% CI,0.09,0.23) after adjusting for demographic and socioeconomic factors and their risk perception of contracting and transmitting COVID-19. Belief in the freedom to choose whether or not to accept vaccinations was a major predictor of COVID-19 vaccine acceptance among a sample of unvaccinated individuals in Italy in May 2021. This understanding of how individuals prioritize personal freedoms and the perceived benefits and risks of vaccines, when making health care decisions can inform the development of public health outreach, educational programs and messaging.

The ethanol extract (EE) prepared from the leaves of Tibouchina granulosa, and its fraction in ethyl acetate (fEA) were evaluated concerning their capacity to reduce inflammation in different experimental models. fEA was also studied concerning its chemical constituents. EE and fEA were assayed for their anti-inflammatory potential, using formalin-induced licking behaviour and carrageenan-induced inflammation into the subcutaneous air pouch (SAP) models. Reduction in polymorphonuclear cells (PMN) activation was performed in freshly isolated PMN. Chromatographic analysis of fEA was done by HPLC. Hispiduloside was isolated as the main constituent in fEA and its quantity was estimated to be 11.75% in fEA, 3.05% in EE, and 0.2% (w/w) in the plant. EE (30 mg/kg) significantly reduced the second phase of formalin-induced licking. fEA demonstrated a reduction in leukocyte migration into the SAP. EE and fEA drastically reduced cytokines (TNF-α, IL-1β, and IFN-γ), nitric oxide (NO) production, in vitro PMN migration induced by C5a and IL-8, and TNF-α and IL-1β gene expression. Taken together our data indicate that either ethanol extract or its fEA fraction from leaves of T. granulosa present an anti-inflammatory effect contributing to the pharmacological and chemical knowledge of this species and confirming the rationale behind its traditional use.

The occurrence of conversion of agricultural land can cause erosion proneness, low fertility soils, and decreased land productivity. Land conversion requires an evaluation of land capability, as a basis for direction to maintain land productivity. This study aims to determine the rate of conversion of agricultural land, land capability class, the determinants of land capability, and direction of land management on initial land and converted land in agricultural land, Nguntoronadi District, Karanganyar Regency. The method used is a survey, with the research area divided into 6 LMU (Land Map Units) represented by 6 sample points in each LMU including 3 points on fixed land and 3 points on converted land, resulting in 36 samples determined by purposive sampling. The research stages include; 1) Pre survey, 2) Survey, 3) Post survey. The results of the study show that the land-use change from 2011 to 2020 covers an area of 258.56 ha and a rate of 28.73 ha per year. The land capability of the research area on fixed land and converted land is classified into land capability III and class IV. Factors that determine land capability include soil erodibility and drainage. The recommended direction for land use and management for Nguntoronadi District is the provision of green manure, making terracing, and making drainage irrigation
New Indicators ‘Acircularity’ and ‘Resource Efficiency Account’ to Evaluate the Efforts of Eco-Design in Circular Economy

This study proposes new indicator, Resource Efficiency Account (REA). REA represents the effects of eco-design efforts in achieving a circular system. The key concept of REA is “acircularity.” “Acircularity” is the distance to the ideal circular system to be achieved. REA is given as material efficiency (service per total value of constituent materials) divided by acircularity. Acircularity is the sum of the value of resources that the techno-sphere demands from the eco-sphere, and the value of resources that are dissipated within the techno-sphere. If an utterly circular state is reached, the acircularity value is zero. Additionally, this study proposes a new method to quantify the decline of the quality of scrap provided to the market as a decline in the value of the material to calculate the dissipation. The calculation focuses on the control level of impurities in scrap. The validity of these indicators is discussed using an automobile case. Differences in the current circulation level, eco-design for recycling, and refurbishment efforts can be quantitatively evaluated using REA and acircularity.

The tire industry has employed effective CO2 reduction measures in the form of retread tires, which replace only those components that are exposed to the road’s surface. Due to safety concerns, lack of manufacturing technology, high cost, and other issues, retread tires in passenger cars are currently unavailable in Japan. This study aims to analyze the production cost and environmental impacts of retread tires in passenger cars in Japan. This study considered investments in and economies of scale of retread tires, which have lower profit margins than new tires after safety and manufacturing technology issues have been resolved; this is done when the carbon tax is equal to that in the EU. This reserach further examined the proportion of retread tires and new tires that are produced. The primary goal of this study is to determine which ratio of retread vs. new tire production is feasible for an optimal business portfolio. If a carbon tax equivalent to that in the EU was introduced in Japan and each company offered retread tires for passenger cars, this setup would not be profitable and overall costs would need to be lowered. To achieve this cost-effectiveness, it is necessary to extend the life of the equipment and to lower the initial investment. Furthermore, by calculating the costs involved using realistic production expenses, a more realistic cost for the introduction of retread tires for passenger cars can be achieved.

With the development of artificial intelligence, image recognition has seen wider adoption. Here, a novel paradigm image recognition system is proposed for detection of fires owing to the compression of lithium-ion batteries at recycling facilities. The proposed system uses deep learning method. The SparkEye system is proposed, focusing on the early detection of fires as sparks, and is combined with a sprinkler system, to minimize fire-related losses at affected facilities. Approximately 30,000 images (resolution, 800 × 600 pixels) were used for training the system to >90% detection accuracy. To fulfil the demand for dust control at recycling facilities, air and frame camera protection methods were incorporated into the system. Based on the test data and realistic workplace feedback, the best placements of the SparkEye fire detectors were crushers, conveyors, and garbage pits.

In the wake of rapid advances in design and production technologies, differentiating products based on their quality has become a challenge. Against this backdrop, design has become an important factor in determining product value. Design is a creative activity influenced by the experience and sensitivity of designers, who are required to understand the preferences and needs of customers and reflect them in their designs. Accordingly, there is a need to efficiently determine customer preferences. Although it is possible to extract customers’ apparent preferences through interviews and questionnaires, these may be arbitrary. Additionally, to respond to the recent diversification of customer preferences, it is not enough to understand apparent preferences; latent preferences must also be extracted. However, they are vague and cannot be expressed in words by the customers. Unfortunately, a practical method for extracting latent preferences has not yet been developed. In this study, we propose a method for extracting latent customer preferences. We develop a system for recommending products that customers are likely to prefer from among existing products, and develop a system for creating original product designs that customers are expected to prefer. We experimentally verify the usefulness of this method.

Remanufacturing policies have been gradually introduced in Asian countries, such as China, Japan, Malaysia, Singapore, and Thailand. This paper reviews the process of diffusion of remanufacturing policy in Asia. The mechanism of this diffusion is also discussed. The United States began to promote the idea of remanufacturing around the year 2000 through bilateral free trade agreements with Asian countries and international forums such as G8 and the Asia-Pacific Economic Cooperation (APEC). This paper reviews the various efforts on remanufacturing in Asian countries and discusses policy options for promoting remanufacturing. It is crucial to identify the ways to promote remanufacturing in each country in the region to improve resource efficacy and strengthen the circular economy in Asia.
