The Wearable Internet of Things Care System primarily supports the development of portable physiological signal detection devices and electronic fences.
0.3-V Voltage-Mode Versatile First-Order Analog Filter Using Multiple-Input DDTAs
Authors: Kumngern Montree , Khateb Fabian , Kulej Tomasz , Steffan Pavel
Published: June 2023

This paper presents a versatile first-order analog filter using differential difference transconductance amplifiers (DDTAs). The DDTA employs the bulk-driven (BD) multiple-input MOS transistors technique (MI-MOST) operating in the subthreshold region. This results in low-voltage and low-power operational capability. Therefore, the DDTA, designed using 130 nm CMOS technology from UMC in the Cadence environment, operates with 0.3 V and consumes 357.4 nW. Unlike previous works, the proposed versatile first-order analog filter provides first-order transfer functions of low-pass, high-pass, and all-pass filters within a single topology. The non-inverting, inverting, and voltage gain of the transfer functions are available for all filters. Furthermore, the proposed structure provides high-input and low-output impedance, which is required for voltage-mode circuits. The pole frequency and voltage gain of the filters can be electronically controlled. The total harmonic distortion of the low-pass filter was calculated as −39.97 dB with an applied sine wave input signal of 50 mVpp@ 50 Hz. The proposed filter has been used to realize a quadrature oscillator to confirm the advantages of the new structure.

Published: June 2023

Predictable logistics disruptions due to scheduled lockdowns for large-scale events such as the Olympic Games may not only reduce supply chain profits, but also increase carbon emissions. To help solve these problems, an emergency transit policy to be applied to the logistics path is an effective solution. However, optimal inventory control is needed. This paper proposes an optimization model to control ordering and inventory policies for decentralized and centralized supply chains. The model considers the logistics path damping coefficient, the logistics path acceleration coefficient, and the vehicle loading capacity ratio in emergency transit. Our major findings include the following. First, supply chain profits under centralization are confirmed to be higher than under decentralization. Second, a price discount mechanism can achieve supply chain coordination. Third, the manufacturers in a centralized supply chain are more inclined to choose a logistics path with a high acceleration coefficient in order to let their cargo arrive quickly and to reduce the impact of the lead time demand fluctuations. Finally, the implications of our research results for carbon emission reductions are discussed.

Published: June 2023

Based on a field investigation conducted in May 2019, the spatial distribution characteristics of dissolved organic matter (DOM) in sediments of Wuli Lake in the Taihu Lake basin were analyzed using ultraviolet-visible (UV-Vis) absorption spectroscopy and three-dimensional fluorescence spectroscopy. The results showed that: (1) The overall water quality of West Wuli Lake was significantly better than that of East Wuli Lake. The water transparency, measured in Secchi depth (SD), of West Wuli Lake was higher than that of East Wuli Lake, while the suspended solids (SS), total nitrogen (TN), total phosphorus (TP) and chlorophyll a (Chl-a) were higher in East Wuli Lake than in West Wuli Lake. (2) The spatial distribution of a(350), M and SR values of DOM in surface sediment in Wuli Lake differed; a(350) values were highest in the northwestern part of Wuli Lake, while M and SR values were highest in the eastern part. The mean value of SR in Wuli Lake was 2.12 ± 0.67, indicating that the DOM contained more authigenic humus; the mean M value was less than 3.5, indicating that the proportion of humic acid was higher than that of fulvic acid. (3) The ranges of the biogenic index (BIX), the humic index (HIX) and the fluorescence index (FI) of surface sediments in Wuli Lake were 0.64~0.85, 3.79~4.84 and 1.72~1.84, respectively, indicating that surface sediments in Wuli Lake were characterized by authigenic sources, and the humic components of DOM in sediments were characterized by a dual contribution from terrestrial and endogenous sources.

Published: June 2023

The development of hybrid electric vehicles (HEVs) is rapidly gaining traction as a viable solution for reducing carbon emissions and improving fuel efficiency. One type of HEV that is gaining significant interest is the fuel cell/battery/supercapacitor HEV (FC/Bat/SC HEV), which combines fuel cell, battery, supercapacitor, AC, and DC generators. These FC/B/SC HEVs are particularly appealing because they excel at efficiently managing energy and cater to a wide range of driving requirements. This study presents a novel approach for exploiting the kinetic energy of a sensorless HEV. The vehicle has a primary fuel cell resource, a supercapacitor, and lithium-ion battery energy storage banks, where each source is connected to a special converter. The obtained hybrid system allows the vehicle to enhance autonomy, support the fuel cell during low production moments, and improve transient and steady-state load requirements. The exploitation of kinetic energy is performed by the DC and AC generators that are linked to the electric vehicle front wheels to transfer the HEV’s wheel rotation into power, contributing to the overall power balance of the vehicle. The energy management system for electric vehicles determines the FC setpoint power through the classical state machine method. At the same time, a robust speed controller-based artificial intelligence algorithm reduces power losses and enhances the supply efficiency for the vehicle. Furthermore, we evaluate the performance of a robust controller with a speed estimator, specifically using the adaptive neuro-fuzzy inference system (ANFIS) and the model reference adaptive system (MRAS) estimator in conjunction with the direct torque control-support vector machine (DTC-SVM), to enhance the torque and speed performance of HEVs. The results demonstrate the feasibility and reliability of the vehicle while utilizing the additional DC and AC generators to extract free kinetic energy, both of which contributed to 28% and 24% of the total power for the vehicle, respectively. This approach leads to a vehicle supply efficiency exceeding 96%, reducing the burden on fuel cells and batteries and resulting in a significant reduction in fuel consumption, which is estimated to range from 25% to 35%.
The Polarization Effect and Mechanism of China’s Green Finance Policy on Green Technology Innovation
Authors: Zhang Wenqing , Dong Jingrong
Published: June 2023

The advancement of green technology innovation (GTI) is crucial for facilitating green development. China, the largest carbon-emitting economy, should prioritize the acceleration of GTI to augment global green economic growth and reduce carbon emissions. Green finance policy (GFP) is a common instrument for encouraging enterprises to develop GTI. This study, therefore, takes the pilot policy of China’s Green Finance Reform and Innovation Pilot Zone as a “quasi-natural experiment” and uses the difference-in-differences method to explore the impact and mechanism of GFP on Chinese enterprises’ GTI. Based on the empirical analysis using microdata from Chinese industrial enterprises from 2015 to 2021, the following conclusions can be drawn. First, GFP has a green innovation polarization effect. It facilitates the development of GTI in green enterprises while hindering the progress of GTI in polluting enterprises. Second, GFP enhances the GTI of green enterprises by promoting innovative behaviors and factor allocation optimization behaviors. However, GFP reduces the GTI of pollution enterprises by promoting non-innovative investments and reducing the efficiency of factor allocation optimization. Third, the combination of policies utilizing GFP, environmental subsidy, and R&D subsidy can effectively increase the GTI of polluting enterprises without compromising the GTI of green enterprises. This study offers empirical evidence and policy recommendations for establishing a green finance system in developing countries.

Authors: de Almeida Giovana Goretti Feijó
Published: June 2023

Cities involve units of time and space, being part of historical, social, economic, cultural, and tourist imaginary constructions. The goal is to understand how the territorial brand, based on regional development theories, is being used in the metaverse city of Seoul, South Korea. The method used was a case study associated with bibliographic and documentary research, using a protocol with four analytical categories. The main results referred to a metaverse territorial-regional brand, bringing discussions about a new geographical-virtual-immersive metaverse scale. It also addressed the use of recognition and competitiveness strategies between interactive-immersive territories. The conclusion confirms that Seoul’s metaverse territorial-regional brand is strategically divided into three situations: (1) For city marketing purposes, positioning it as the first metaverse global city; (2) in city branding to strengthen the reputation and identity of the territory; and (3) to drive the transformation of physical territory with urban revitalization projects from the metaverse environment. Moreover, it serves Metaverse Seoul as an interactive and immersive field laboratory in virtual reality.

Authors: Alenezi Anwur , Alabaiadly Yousef
Published: June 2023

All living organisms depend on water for their survival. Therefore, sufficient water availability is necessary for health. During the last few years, considerable progress has been made in the production of clean drinking water—particularly in the desalination industry. Various methods have been explored to boost the productivity of solar stills. The present review focuses on recent enhancement techniques aimed at boosting their performance—particularly those incorporating non-metallic nanofluids into the base fluid. The nanomaterials examined in this review include Al2O3, CuO, ZnO, and TiO2. Several studies adding Al2O3 in a solar-still desalination system resulted in an increase in distillate yield, better efficiency, reduced energy consumption, reduced thermal loss, and better productivity. The incorporation of CuO in a solar-still desalination system led to major improvements in performance. These included enhanced daily efficiency, better productivity, improved production of freshwater, and higher energy and exergy efficiency. The incorporation of TiO2 in a solar-still desalination system resulted in increased productivity, better thermal conductivity, better thermal efficiency, higher daily distillate output, and high levels of water temperature. It was also evident that the incorporation of ZnO in a solar-still desalination system resulted in a substantial increase in the output of clean water and occasioned improvements in productivity and overall efficiency. Together, these findings demonstrate the potential of these nanomaterials to significantly enhance the performance of solar-still desalination systems. Other nanomaterials that are yet to gain increased use, such as SiO2 and SnO2, have also been discussed. The collective results in this paper demonstrate the potential of nanofluids to enhance the performance and effectiveness of solar-still desalination systems. This review provides conclusive evidence of the positive effects of different nanofluids on the yield, productivity, energy, and efficiency of diverse types of solar stills, offering promising advancements in the sustainable production of water.
Structural Classification, Discharge Statistics, and Recession Analysis from the Springs of the Gran Sasso (Italy) Carbonate Aquifer; Comparison with Selected Analogues Worldwide
Authors: Medici Giacomo , Lorenzi Valeria , Sbarbati Chiara , Manetta Mauro , Petitta Marco
Published: June 2023

The relative importance of karst conduits and fractures in driving groundwater flow affects the discharge of springs and the long-term availability of water resources. Applying statistics to the hydrographs of the discharge and studying the recessions provide information on the degree of reliability and variability of the springs and, therefore, the flow regime within the saturated part of the carbonate aquifers. This approach was applied to six springs at the Gran Sasso aquifer in Central Italy. These springs were divided into three structural geological groups that determined the position of the permeability thresholds. The type of tectonic structures and the pattern of the permeability thresholds allow a correlation with the computed statistics. The studied springs were associated with the presence of thrusts, overturned drag folds, and a normal fault. The computed statistics describe a general scenario of reliability and steadiness for the springs. The Flow Duration Curves for the springs show limited groundwater flow through the conduits through a comparison with analogues in Slovakia. Joints and bedding plane fractures dominate the groundwater flow, fitting both the relative steadiness of the discharges and the pattern of the Flow Duration Curves. The recessions are also characterized by more gentle slopes with respect to nearby areas fitting a conceptual model of dominant fracture flow. This mathematical scenario depicts groundwater resources, which have limited exposure to episodes of summer droughts. The proposed approach is a holistic combination of structural geology and hydrologic elements and can be successfully exported to other tectonized carbonate areas for the sustainable management of groundwater resources worldwide.

Authors: Wang Yiran , Jin Shuowei , Cheng Ming
Published: June 2023

This paper proposes a novel convolution–non-convolution parallel deep network (CNCP)-based method for electricity theft detection. First, the load time series of normal residents and electricity thieves were analyzed and it was found that, compared with the load time series of electricity thieves, the normal residents’ load time series present more obvious periodicity in different time scales, e.g., weeks and years; second, the load times series were converted into 2D images according to the periodicity, and then electricity theft detection was considered as an image classification issue; third, a novel CNCP-based method was proposed in which two heterogeneous deep neural networks were used to capture the features of the load time series in different time scales, and the outputs were fused to obtain the detection result. Extensive experiments show that, compared with some state-of-the-art methods, the proposed method can greatly improve the performance of electricity theft detection.

Published: June 2023

Environmental education (EE) trains individuals to preserve ecological balance and understand the link between humanity and environmental protection. On the other hand, education for sustainable development (ESD) addresses social, cultural, political, and quality of life factors, and promotes the sustainable evolution of the planet. In Colombia, EE is more recognized compared to ESD, and this situation relates the objective of this research, to investigate the strategies applied in EE and ESD in the official primary and secondary (K-12) educational institutions in the department of Boyacá. This study used a Likert scale survey with numerical values from 1 to 5 to evaluate each category of choice among a targeted population. The results indicate that topics such as water resource conservation and protection of fauna and flora are covered in EE, while ESD issues are less prominent. The findings of this research suggest interventions to improve the implementation of ESD and contribute to the advancement of quality education in the country. It is appropriate to explore different methods to integrate environmental, economic, and social aspects in educational contexts, with the implementation and updating of curricula to improve ESD.
Does the Policy of Decoupled Subsidies Improve the Agricultural Economic Resilience?—Evidence from China’s Main Corn Producing Regions
Authors: Yang Qifeng , Zhang Pingyu , Li Yuxin , Ning Jiachen , Chu Nanchen
Published: June 2023

Various forms of agricultural subsidy policies often have a significant impact on the development of the agricultural economy and also shape the differentiated spatial pattern of regional agricultural economic resilience, while research on the evolution process of agricultural economic resilience and its influencing mechanisms is still very scarce. This study is based on the impact of China’s cancellation of the temporary corn storage policy on corn prices in 2016. By using an economic resilience analysis framework, we selected the indicators of total agricultural output value and disposable income of farmers to measure the agricultural economic resilience of various cities in Jilin Province and analyzed the characteristics and causes of the spatio-temporal change in agricultural economic resilience in Jilin Province from 2008 to 2021. The results show the following: (1) The transition from price and subsidy integration policy to decoupled subsidy policy helps to shape stronger regional agricultural economic resilience, but due to factors such as farmer policy dependence, low international corn prices, severe oversupply in the domestic corn market, and the suddenness of policy changes, there was a short-term decline in agricultural economic resilience in Jilin Province in the early stage of the decoupled subsidy policy (2016–2017), which rapidly increased after 2017. (2) The agricultural economic resilience levels of cities in Jilin Province showed different spatial differentiation characteristics at different stages within the study period, and the central region, as an important corn production area in Jilin Province, had significant changes in agricultural economic resilience. (3) During the execution of the price and subsidy integration policy, the enhancement of agricultural input capacity and agricultural output capacity helped to improve regional agricultural economic resilience; during the execution of the decoupled subsidy policy, the government’s support for agriculture and the potential of rural markets had a significant impact on the improvement of agricultural economic resilience. At the same time, the interaction and enhancement effect between influencing factors also had a profound impact on agricultural economic resilience.

Published: June 2023

Today, mankind is facing one of the greatest challenges detrimental to its well-being, even its survival—climate change. Given that scientists agree that climate change is caused by humans, efforts are being made to change human behavior in order to avoid any tragic consequences. Research indicates that people are more likely to practice sustainable behavior to act on climate change if they are convinced that it actually exists and that it is predominantly caused by human activity. In this context, we have tried to determine what attitudes toward climate change the citizens of Montenegro (declaratively the first ecological country in the world) have and what is their assessment of the importance of sustainable behavior in terms of limiting energy consumption. In order to answer these questions as accurately as possible, it was necessary to make a comparison with other countries where the indicated phenomenon was the subject of research. For this purpose, we used data from the last round (2021) of the European Social Survey (ESS), in which 25 countries participated. The data were obtained by means of a rigorous and standardized collection strategy, ensuring their validity and reliability. The results show significant differences between the countries of Western Europe, post-socialist countries, and Montenegro. The citizens of post-socialist countries display significantly more skepticism toward climate change than those in Western Europe. Furthermore, the citizens of Montenegro are even more skeptical than the average resident of post-socialist societies. The results also show that the attitudes of Montenegrin citizens toward climate change are influenced by some demographic and socioeconomic variables (level of education and material standard), as well as certain value patterns, which we obtained by using Schwartz’s value model.

Authors: Çaloğlu Büyükselçuk Elif , Sarı Yiğit Can
Published: June 2023

People try very hard to have a symmetrical, strong, and beautiful body. The human body needs high amino acids for muscle protein synthesis. Whey protein is a good choice that contains all amino acids, which increases muscle protein synthesis and improves body shape with resistance exercise. For this reason, those who do sports, especially professionals, prefer to use these products frequently. A large number of commercial whey protein powders are sold on the market, and to achieve maximum purpose, individuals want to use the best one. Intuitionistic fuzzy sets are used in order to minimize the negative effects of the uncertainty environment and ambiguous information encountered in the decision-making process on the solution. In this study, VIKOR, based on the circular intuitionistic fuzzy set, has been used to determine the best whey protein supplement. In line with the comprehensive literature review and expert opinions, the evaluation criteria affecting the selection process have been determined, and the solution of the problem has been focused.
High-Performance Intermediate-Frequency Balanced Homodyne Detector for Local Local Oscillator Continuous-Variable Quantum Key Distribution
Authors: Qi Dengke , Wang Xiangyu , Chen Ziyang , Lu Yueming , Yu Song
Published: June 2023

In the continuous-variable quantum key distribution (CV-QKD) system with a local local oscillator (LLO), the center frequency of the sender and the receiver’s source are not exactly the same and a certain frequency drift exists over time, resulting in the frequency of the signal received near the intermediate frequency. Therefore, the LLO system needs an intermediate-frequency balanced homodyne detector (BHD), which needs better symmetry of the arms of the BHD, to obtain the less-common mode noise. Moreover, the traditional intermediate-frequency receiver in classical communication is not available in the CV-QKD system because of the low quantum-to-classical noise ratio. In view of this, in this paper, we construct a broadband intermediate-frequency BHD based on ratio frequency and integrated circuit technology, whose bandwidth can exceed 270 MHz and whose quantum-to-classical noise ratio can reach 14.9 dB. Meanwhile, the BHD has an excellent linear performance with a gain of 22.4 k. By adopting our intermediate-frequency BHD, the secret key rate of the pilot-sequential Gaussian modulated coherent state CV-QKD system with an LLO can reach over 430.8 kbps of 60 km at the standard fiber length, which paves the way to achieve a high-performance LLO CV-QKD system with intermediate-frequency BHD.

Published: June 2023

Objective: The kinetics of immune responses to various SARS-CoV-2 vaccines in cancer patients were investigated. Methods: In total, 57 cancer patients who received BNT162b2-RNA or BBIBP-CorV vaccines were enrolled. Cellular and humoral immunity were assessed at three-time points, before the first vaccine dose and 14–21 days after the first and second doses. Chemiluminescent microparticle immunoassay was used to evaluate SARS-CoV-2 anti-spike IgG response, and QuantiFERON® SARS-CoV-2 kit assessed T-cell response. Results: Data showed that cancer patients’ CD4+ and CD8+ T cell-median IFN-γ secretion of SARS-CoV-2 antigens increased after the first and second vaccine doses (p = 0.027 and p = 0.042). BNT162b2 vaccinees had significantly higher IFN-γ levels to CD4+ and CD8+ T cell epitopes than BBIBP-CorV vaccinees (p = 0.028). There was a positive correlation between IgG antibody titer and T cell response regardless of vaccine type (p < 0.05). Conclusions: This study is one of the first to investigate cellular and humoral immune responses to SARS-CoV-2 immunization in cancer patients on active therapy after each vaccine dose. COVID-19 immunizations helped cancer patients develop an effective immune response. Understanding the cellular and humoral immune response to COVID-19 in cancer patients undergoing active treatment is necessary to improve vaccines and avoid future SARS pandemics.

Published: June 2023

Background: The administration of the third (or booster) dose of COVID-19 vaccine is important in maintaining protection against SARS-CoV-2 infection or the severity of the disease. In Indonesia, health care workers (HCWs) are among the first to receive a booster dose of the COVID-19 vaccine. In this study, we evaluated the antibody response and adverse events following heterologous booster vaccine using mRNA-1273 among HCWs that were fully vaccinated with inactivated viral vaccine as the priming doses. Methods: 75 HCWs at Dr. Soetomo General Hospital in Surabaya, Indonesia, participated in this study. The level of antibody against the SARS-CoV-2 receptor binding domain was analyzed at 1, 3, and 5 months following the second priming dose and at 1, 3, and 5 months after the booster dose. Results: We found a significantly higher level of antibody response in subjects receiving a booster dose of the mRNA-1273 vaccine compared to those receiving an inactivated viral vaccine as a booster. Interestingly, participants with hypertension and a history of diabetes mellitus showed a lower antibody response following the booster dose. There was a higher frequency of adverse events following injection with the mRNA-1273 vaccine compared to the inactivated viral vaccine, although the overall adverse events were considered minor. Conclusions: A heterologous booster dose using mRNA vaccine resulted in a high antibody response; however, participants with hypertension and diabetes mellitus displayed a lower antibody response.

Published: June 2023

Background: Hemodialysis patients are at an increased risk of SARS-CoV-2 infection and are excluded from preauthorization COVID-19 vaccine trials; therefore, their immunogenicity is uncertain. Methods: To compare the antibody responses to homologous ChAdOx1 and mRNA-1273 SARS-CoV-2 vaccination in hemodialysis patients, 103 age- and sex-matched hemodialysis patients with two homologous prime-boost vaccinations were recruited to detect anti-receptor-binding domain (RBD) IgG levels and seroconversion rates (SCRs) 14 days after a prime dose (PD14), before and 28 days after a boost dose (pre-BD0 and BD28). Results: Both mRNA-1273 and ChAdOx1 vaccinations elicited immunogenicity in study subjects, and the former induced higher anti-RBD IgG levels than the latter. The SCRs of both groups increased over time and varied widely from 1.82% to 97.92%, and were significantly different at PD14 and pre-BD0 regardless of different thresholds. At BD28, the SCRs of the ChAdOx1 group and the mRNA-1273 group were comparable using a threshold ≥ 7.1 BAU/mL (93.96% vs. 97.92%) and a threshold ≥ 17 BAU/mL (92.73% vs. 97.92%), respectively, but they were significantly different using a threshold ≥ 20.2% of convalescent serum anti-RBD levels (52.73% vs. 95.83%). The seroconversion (≥20.2% of convalescent level) at BD28 was associated with mRNA-1273 vaccination after being adjusted for age, sex, body mass index, and the presence of solicited reactogenicity after a prime vaccination. Conclusion: Our prospective, observational cohort indicates that a full prime-boost mRNA-1273 vaccination is likely to provide higher immune protection in hemodialysis patients compared to ChAdOx1, and this population with a prime-boost ChAdOx1 vaccination should be prioritized for a third dose.
Extreme Summer Precipitation Characteristics and Associated Water Vapor Transport in Southern Xinjiang
Authors: Jin Chen , He Qing , Huang Qian
Published: June 2023

In this study, we analyzed the spatial and temporal characteristics of extreme precipitation in summer in southern Xinjiang (SXJ) using CN05.1 daily precipitation data, the National Centers for Environmental Prediction (NCEP) monthly average data, and ERA5 four-times-daily reanalysis data from 1961 to 2020, determined the interdecadal variation in extreme precipitation, and further explored the circulation mechanisms and anomalous water vapor transport characteristics associated with changes in extreme precipitation. The results showed that extreme precipitation, extreme precipitation days, and extreme precipitation contribution in SXJ all increased significantly, with the turnaround occurring in 1986. Enhanced vertical upward motion, greater convergence of water vapor at lower levels, and a more unstable atmospheric convection led to an increase in extreme precipitation along the southern border region. The eastward Pacific Ocean and southward Indian Ocean provided anomalous water vapor transport, and the boundary water vapor flux trend and its correlated distribution with extreme precipitation showed that southern boundary water vapor transport played an important role in the increase in extreme precipitation. At vertical heights, the dominant longitudinal water vapor transport fluxes were concentrated in the middle and upper layers, whereas the latitudinal water vapor transport fluxes were concentrated in the middle and lower layers.
Meteorological and Limnological Precursors to Cyanobacterial Blooms in Seneca and Owasco Lakes, New York, USA

Published: June 2023

Meteorological and water quality data were collected in offshore and nearshore settings over 4 years in the oligotrophic–mesotrophic Owasco and Seneca Lakes in order to assess cyanobacteria bloom (CyanoHABs) spatial and temporal variability and precursor meteorological and water quality conditions. CyanoHABs were detected from August through mid-October in both lakes. Blooms were temporally and spatially isolated, i.e., rarely concurrently detected at 3 (4.2%) or more of the 12 sites, and blooms (75.6%) were more frequently detected at only 1 of the 12 sites in the 10 min interval photologs. Both lakes lacked consistent meteorological and water quality precursor conditions. CyanoHABs were detected during the expected calm (<1 kph), sunny (600–900 W/m2), and warm water (>23 °C) episodes. However, more CyanoHABs were detected during overcast/shady (<250 W/m2) and windier (1 to 20 kph) and/or in cooler water (16 to 21 °C). More importantly, the majority of the sunny, calm, and/or warm water episodes did not experience a bloom. This suggests that nutrient availability was essential to trigger blooms in these two lakes, and we speculate that the nutrients originate from the decomposition of nearshore organic matter and runoff from the largest precipitation events.

Digital Branding in educational institutions is very crucial to do because it will improve reputation and form an institutional brand image. Regarding the use of digital technology in the Al-Muin Islamic Boarding School environment, currently, it can be said to be very low. This stated shows from the lack of social media owned by the Al-Muin Islamic boarding school. Meanwhile, with social media, the boarding school will be able to communicate and build public relations with the society. Having a relationship with the society will improve the good image of the Islamic boarding school and also as a medium of communication for the boarding school with the soociety. The implementation team of community service activities will assist in the use of social media as a means of digital branding at the Al Muin Syarif Hidayatullah Islamic Boarding School. The teams activity are carried out in four stages, namely: initiation, preparation of facilities and infrastructure, execution and evaluation. The comparison of the pre-test and post-test results shows an increase in the level of understanding of the caregivers of the Al Muin Syarif Hidayatullah Islamic Boarding School in using social media Instagram as a means of digital branding.

This article presents the analysis of evaluation methods used in a well-designed and comprehensive evaluation effort of a significant Extension program. The evaluation data collection methods were analyzed by questionnaire mode and timing of follow-up surveys. Response rates from the short- and long-term follow-ups and different questionnaire modes by occupational categories also were examined. Overall, the electronic questionnaire mode and 2-month follow-ups yielded significantly higher response rates. The findings have implications for meaningfully evaluating Extension programs operating with limited resources. The recommendations are useful to Extension educators who need to decide how to capture program outcomes but have limited resources.

Published: June 2023

One goal of Extension is to provide practical information that makes a difference to producers. Cow Herd Appraisal Performance Software (CHAPS) has provided beef producers with production benchmarks for 30 years, creating a large historical data set. Many such large data sets contain useful information but are underutilized. Our goal was to create a 20-year data set (CHAPS20Y) to examine trends in beef production from 1994 to 2013. In this article, we describe the CHAPS program and the process used to select herds for CHAPS20Y. We hope to publish additional related articles that will examine trends in calving distributions, reproduction, and growth and discuss implications for producers and Extension.

The use of focus groups to formatively evaluate community-based curricula after development and before pilot testing is not highlighted in the literature. In the study discussed in this article, research with four focus groups, composed of 46 women aged 65 years and older and belonging to eight South Carolina Family and Community Leaders clubs, was conducted to evaluate the Cooking Healthy, Eating Smart (CHES) curriculum. The CHES curriculum was tailored based on suggestions from the older adults. Extension professionals can better prepare a curriculum for pilot testing in the community by conducting a formative evaluation using focus groups with community members at this particular stage of development.
A Review of Extension Master Gardener Program Record-Keeping Systems
Authors: Dorn Sheri
Published: June 2023

Record-keeping systems (or volunteer management systems) were identified as a capacity-building tool for Extension master gardener volunteer (EMGV) programs. Not all states have or use such systems, and there are differences among existing systems. A survey was conducted in June 2015 to document and compare record-keeping systems for EMGV programs nationally. Survey results indicate that EMGV programs are still hours-focused in reporting and data collection and that EMGV record-keeping systems offer time-saving benefits for state coordinators, agents, and volunteers. Record-keeping systems also offer potential for further engaging Extension master gardeners in Extension outreach and demonstrating educational impact in communities.
