Protected agriculture has great potential for the vegetable industry in the Philippines as it allows the application of modern cultivation techniques to mitigate adverse weather conditions and enable farmers to manage pests and diseases efficiently. Thus, to address the increasing demand for food in the Philippines, one strategy to increase vegetable production which is tested and/or proven is through the intensified use of protective structures. This review describes the magnitude and potential of agriculture in the Philippines, focusing on the protected cultivation of horticultural crops. The Philippines is far behind in greenhouse technologies compared to other Asian countries where thousands to millions of hectares are used for protected vegetable cultivation. Several studies have investigated the economic viability and applicability of low- and high-cost protective structures in typhoon-prone countries such as the Philippines, demonstrating that protective structures are feasible and profitable. Also, the impact of protected cultivation as compared to the open field has resulted in significantly higher yield and better quality of produce. Hence, the Philippine government with the assistance of the Republic of Korea agreed to improve the country’s flagging vegetable industry and endeavor to attain the status of a food-secure country through the establishment of smart greenhouse technologies. Overall, despite the limitations due to the high cost of electricity and construction protected cultivation facilities including required technologies provide greater advantages for seasonal and off-seasonal vegetable crop production compared to that in the open field. Moreover, such technology can be applied to various geographical locations such as plains, hills, deserts, rural, and urban areas.

The successful implementation of green supply chain management(GSCM) practices requires a level of cooperation that can be difficult to conduct. Despite this challenge, limited scholarly attention has been paid to exploring how the implementation of GSCM practices can be effectively facilitated and enhanced through accumulated social capital with suppliers. Based on social capital theory, this study postulates that supplier network characteristics derived from social capital with key suppliers can be critical antecedents of GSCM, which in turn enhances the firm’s environmental performance. To test hypotheses, data were collected from 330 firms in 15 countries, and structural equation modeling was employed. Results show that GSCM improves environmental performance, and structural and cognitive social capitals of the supplier network act as antecedents and lead to GSCM implementation.

In recent years, ESG activities (Environment, Social and Governance) have been paid more and more attention by enterprises and their stakeholders in various countries. China is the largest developing country in the world. The ESG performance of Chinese listed enterprises helps to understand the shortcomings of their sustainable development ability and further enhance the firm value. Moreover, the interaction effect between green innovation investment and ESG activities is of great significance for enterprises to balance the resource allocation between the two factors in the future. Taking listed Chinese manufacturing companies from 2011 to 2020 as an example, this study investigates the influence of ESG activities on financial performance and non-financial performance, and tests the moderating role of green innovation. Our results show that: (1) ESG performance has a negative impact on financial performance; (2) ESG performance has a positive impact on non-financial performance; (3) Green innovation can positively adjust the negative impact of environmental activities on financial performance. However, it will enhance the negative impact of governance activities on financial performance. The interaction effect between green innovation and social activities on corporate financial performance is a substitution effect; (4) With the improvement of green innovation level, the positive impact of ESG overall performance and environmental performance on corporate reputation will also be suppressed.

Chlorine dioxide (ClO2) has recently emerged as an ideal disinfectant and has shown a wide range of antimicrobial activities in various pathogenic microorganisms. In this study, the virucidal effect of ClO2 at low concentration (0.02 ppm) and higher concentration (0.06 – 0.09 ppm) against Adenovirus and Herpesvirus was evaluated based on the NF T 72-281 and ASTM 1053-11 standard methods at different exposure times. The virus suspension was dried onto the carrier and then exposed to gaseous ClO2 (gClO2) at 22 ± 2∘C. For Adenovirus, exposure at a low concentration of ClO2 at the middle height resulted in the average log10 reduction of 0.95, 2.65, and 5.30 after 1, 3, and 6 h post-exposure (pe), respectively. Moreover, more than 4-log10 reduction was achieved at 4 and 6 h pe with higher concentrations of ClO2. On the other hand, the antiviral activity of gClO2 at the middle height was also effective against Herpesvirus. In particular, at 1 h pe, a less than 4-log10 reduction was observed at all examined concentrations of ClO2, whereas exposure for 3 and 6 h (with low concentration) or 2 h (with higher concentration) inactivated completely viruses attached to the carrier. These results suggested that ClO2 fumigation is a potential alternative method for disinfecting healthcare facilities, high-containment laboratories, and households with a safe concentration for human health.

A step toward world peace could be achieved by Korea, Japan, and the United States jointly celebrating their promotion of cherry blossom festivals based on Jeju Island native Prunus Yeodensis, or Somei- Yoshino Cherry trees. Based on bio-diplomacy, this celebration of new beginnings and the emphemeral nature of the material world could be a foundation for peace-building by these three nations and others and for putting aside past grievances.

Aluminum (Al) is one of the major factors adversely affects crop growth and productivity in acidic soils. In this study, the effect of Al on plants in soil was investigated by comparing the protein expression profiles of alfalfa roots exposed to Al stress treatment. Two-week-old alfalfa seedlings were exposed to Al stress treatment at pH 4.0. Total protein was extracted from alfalfa root tissue and analyzed by two-dimensional gel electrophoresis combined with MALDI-TOF/TOF mass spectrometry. A total of 45 proteins differentially expressed in Al stress-treated alfalfa root tissues were identified, of which 28 were up-regulated and 17 were down-regulated. Of the differentially expressed proteins, 7 representative proteins were further confirmed for transcript accumulation by RT-PCR analysis. The identified proteins were involved in several functional categories including disease/defense (24%), energy (22%), protein destination (9%), metabolism (7%), transcription (5%), secondary metabolism (4%), and ambiguous classification (29%). The identification of key candidate genes induced by Al in alfalfa roots will be useful to elucidate the molecular mechanisms of Al stress tolerance in alfalfa plants.

This case report describes satisfactory correction of deep and large canine corneal ulcerations by application of bidirectional corneo-conjunctival transposition (CCT). A 12-year-old spayed female Maltese dog with a large corneal descemetocele, perforation, and blepharospasm of the right eye was referred to Chungbuk National University Veterinary Teaching Hospital. More than half of the thickness of the cornea was damaged, and the ulcer was progressive. On ophthalmic examination, menace response and dazzle reflex were absent. No corneal melting was observed. As the patient had large and deep corneal ulcers, traditional one-sided CCT was not sufficient to cover the wound lesion. To increase corneal transparency after recovery, we decided to perform bidirectional CCT from 12 o’ clock on the dorsal side to 7 o’ clock on the ventral side. The dog was medicated with topical eye drops, ofloxacin, atropine, and moxifloxacin before surgery. Debridement with a diamond burr was then performed around the descemetocele. Five weeks after surgery, the dazzle reflex was restored as the blood vessel receded from the cornea to the conjunctiva. Eight weeks after surgery, corneal transparency and corneal stability were gradually restored, but not completely. Bidirectional CCT provides structural support and helps corneal wound healing in large canine corneal ulceration.

We present the analysis of a planetary microlensing event OGLE-2019-BLG-0362 with a shortduration anomaly (∼0.4 days) near the peak of the light curve, which is caused by the resonant caustic. The event has a severe degeneracy with Δχ2 = 0.9 between the close and the wide binary lens models both with planet-host mass ratio q ≃ 0.007. We measure the angular Einstein radius but not the microlens parallax, and thus we perform a Bayesian analysis to estimate the physical parameters of the lens. We find that the OGLE-2019-BLG-0362L system is a super-Jovian-mass planet Mp = 3.26+0.83 −0.58 MJ orbiting an M dwarf Mh = 0.42+0.34 −0.23 M⊙ at a distance DL = 5.83+1.04 −1.55 kpc. The projected star-planet separation is a⊥ = 2.18+0.58 −0.72 AU, which indicates that the planet lies beyond the snow line of the host star.

There is a need for the purification of indoor air owing to a high rate of pollution in today’s world. For this, cabin air filters (CAFs) are widely used, which requires the addition of certain adsorbents to increase the volatile organic compound (VOC) removal efficiency. However, this addition causes high-pressure resistance, which may hamper commercial applications by requiring more energy and negatively affecting fresh air delivery rate. Hence, in this study, a high-performance combined CAF (CCAF) with excellent dust and chemical filtration performance and low differential pressure was prepared using granular activated carbon (GAC)/activated carbon fiber (ACF) mixed medium. The GAC/ACF mixed medium had higher air permeability than the ACF medium of the same weight, and it exhibited similar ultrafine dust filtration performance to the ACF medium without an increase in differential pressure. In addition, the GAC/ACF mixed medium showed excellent gas removal performance without increasing differential pressure by combining the VOC removal characteristics of the GAC and ACF filter media. The improved VOC removal performance of the GAC/ACF mixed medium was due to the hybrid effect of the hierarchical pore structures of the GAC and the nearly uniform pore structures of the ACF, which resulted in a slow and increased gas adsorption by the GAC and rapid gas adsorption of the ACF.

A thermally conductive film can be used to laterally conduct heat along the surface of glass windows, toward its edges where a heat sink could be located, thereby reducing temperature differential between the inside and outside surfaces of the window and thus lowering cross-sectional conductive heat transfer. This technique can offer optimized thermal energy management to modern buildings without the weight and cost of double- or triple-glazed window panels. In this work, a thermally conductive film was developed using carbon dots with inherently high thermal conductivity. Nitrogen atoms were then added to the carbon dots structure to intensify high-frequency phonon that would result in higher lateral thermal conductivity. The nitrogen-decorated carbon dots (NCDs) were prepared by a simple hydrothermal synthesis of citric acid with the addition of ethylenediamine as the N source. The NCDs were added to a cellulose-based solution and drop-casted onto FTO glass resulting in a transparent, laterally thermally conductive film, that also blocks ultraviolet (UV) and high-intensity blue light radiation. The visible-light transmission of the NCDs’ film was found to be up to 65%, comparable to the commercial solar films. The lateral thermal conductivity of the NCDs’ film increases with increasing N content up to an optimum level, suggesting the role of N to “concentrate’ the high-frequency phonons responsible for effective lateral thermal conductivity of the films.

As frontier materials, graphene oxide (GO) and graphene have penetrated almost all research areas and advanced numerous technologies in sensing, electronics, energy storage, catalysis, water treatment, advanced composites, biomedical, and more. However, the affordable large-scale synthesis of high-quality GO and graphene remains a significant challenge that negatively affects its commercialisation. In this article, firstly, a simple, scalable approach was demonstrated to synthesise high-quality, high yield GO by modifying the improved Hummers method. The advantages of the optimised process are reduced oxidation time, straightforward washing steps without using coagulation step, reduction in cost as eliminating the use of phosphoric acid, use of minimum chemical reagents, and increased production of GO per batch (~ 62 g). Subsequently, the produced GO was reduced to reduced graphene oxide (rGO) using three different approaches: green reduction using ascorbic acid, hydrothermal and thermal reduction techniques. The GO and rGO samples were characterised using various microscopy and spectroscopy techniques such as XRD, Raman, SEM, TEM, XPS and TGA. The rGO prepared using different methods were compared thoroughly, and it was noticed that rGO produced by ascorbic acid reduction has high quality and high yield. Furthermore, surface (surface wettability, zeta potential and surface area) and electrical properties of GO and different rGO were evaluated. The presented synthesis processes might be potentially scaled up for large-scale production of GO and rGO.

Due to its capacity to manufacture low-cost 3D-printed structures, 3D-printing technology offers a unique opportunity for the fast epitome of various applications. Using a typical fused deposition modeling 3D printer along with a Discovery extruder, a graphene-ink can be 3D printed to produce an interdigitated electrode (IDE) arrangement. This work fabricated a 3D-printed planar supercapacitor from pristine graphene-ink without using high-temperature processing or functional additives. The printable ink (89%) is formulated from pristine graphene without the addition of any functional additives. The symmetric flexible supercapacitor is demonstrated with an excellent specific capacitance of 137.50 F/g at 0.5 A/g and an energy density of 12.23 Wh/kg. The obtained gravimetric energy density beats reported earlier carbon-based supercapacitors that are 3D or inkjet printed. The flexibility and robustness of 3D-printed devices are achieved up to 150° folding angles. This work demonstrates an efficient and easy method for fabricating practical energy storage devices featuring a customizable shape and excellent flexibility.

Abstract Biosensors are a group of measurement systems and their design is based on the selective identification of analyses based on biological components and physical and chemical detectors. Biosensors consist of three components: biological element, detector, and converter. The design of biosensors in various fields of biological sciences, medicine has expanded significantly. Biosensor technology actually represents a combination of biochemistry, molecular biology, chemistry, physics, electronics, and telecommunications. A biosensor actually consists of a small sensor and biological material fixed on it. Because biosensors are a powerful tool for identifying biological molecules, today they are used in various medical sciences, chemical industry, food industry, environmental monitoring, pharmaceutical production, health, etc. In fact, these sensors are a powerful tool to identify biological molecules. In fact, biosensors are analytical tools that can use biological intelligence to detect and react with a compound or compounds, and thus create a chemical, optical, or electrical message. The basis of a biosensor is to convert a biological response into a message. In this category, the use of telecommunication engineering technology and electromagnetic waves and frequency and radio spectrum is growing more and more to detect, measure, and determine the desired parameters in microbiology and laboratory sciences. The use of radio, optical, electromagnetic, ultrasonic, and infrared wave detection technology is part of the applications of telecommunication science in this field. Even image and audio processing systems have been instrumental in the discussion of biosensors in microbiology. The science of using fiber optics and waveguides, micro-strip antennas, and microelectromechanical technology is also very efficient in the construction and design of these biosensors.

The study aims to analyse data security in the financial and banking sector of China. The data laws provide a ‘consent-oriented’ approach where consent, along with a limited list of exceptions, is the legal basis for the processing of personal information. The personal data protection mechanism comprised the Data Security Law, the Cybersecurity Law, and the Personal Information Protection Law. Taken together, they cover all areas of information security and establish a severe data protection regime: they determine the scope of regulation, objects and subjects, responsibility, and institutional control mechanisms. For an accurate assessment, it is necessary to wait for the adoption of by-laws that specify the provisions of these laws. The financial and banking sector already has several by-laws in place that set stringent standards for the security of personal information. The leading role in this mechanism is taken by the financial regulator - the People’s Bank of China.

This study was carried out to evaluate the seeding date and performance of early maturing rye cultivars for the Dry matter yield (DMY) and nutritive value during 2016 and 2017 in Yeongseo region of Gangwondo, South Korea. The experimental field was designed as a split-plot arrangement. The treatments were two planting dates on September 25 and October 02 as the main plots, and two cultivars of forage rye including Gogu and Koolgrazer as sub-plots. The cultivars were harvested on April 26 at the heading stage of both years. In this experiment, the sowing dates and cultivars of the forage rye did not effect on DMY. The DMY had no significant differences among the cultivars of forage rye and seeding date of both years. Similarly, no significant difference was observed in the DMY of Gogu and Koolgrazer in both seeding date and years. The CP, NDF, ADF, and RFV had no significant differences among the cultivars of forage rye and seeding date of both years. Considering the DMY and nutritive value of the current experiment, seeding of forage rye cultivars Gogu and Koolgrazer on September 25 and October 2 could be used as an recommended seeding date at northern area. In addition, based on the climate characteristics of the region, both cultivars had relatively similar forage yield and quality that makes them to be recommended for cultivation in the region. This study is meaningful in that DMY was first presented in Yeongseo region where there is no cultivation data for forage rye.
