| ○ | ○ | Article | Comparative Evaluation of Top-Down GOSAT XCO2 vs. Bottom-Up National Reports in the European Countries | Submitting national inventory reports (NIRs) on emissions of greenhouse gases (GHGs) is obligatory for parties of the United Nations Framework Convention on Climate Change (UNFCCC). The NIR forms the basis for monitoring individual countries' progress on mitigating climate change. Countries prepare NIRs using the default bottom-up methodology of the Intergovernmental Panel on Climate Change (IPCC), as approved by the Kyoto protocol. We provide tangible evidence of the discrepancy between official bottom-up NIR reporting (unit: tons) versus top-down XCO2 reporting (unit: ppm) within the European continent, as measured by the Greenhouse Gases Observing Satellite (GOSAT). Bottom-up NIR (annual growth rate of CO2 emission from 2010 to 2016: -1.55%) does not show meaningful correlation (geographically weighted regression coefficient = -0.001, R-2 = 0.024) to top-down GOSAT XCO2 (annual growth rate: 0.59%) in the European countries. The top five countries within the European continent on carbon emissions in NIR do not match the top five countries on GOSAT XCO2 concentrations. NIR exhibits anthropogenic carbon-generating activity within country boundaries, whereas satellite signals reveal the trans-boundary movement of natural and anthropogenic carbon. Although bottom-up NIR reporting has already gained worldwide recognition as a method to track national follow-up for treaty obligations, the single approach based on bottom-up did not present background atmospheric CO2 density derived from the air mass movement between the countries. In conclusion, we suggest an integrated measuring, reporting, and verification (MRV) approach using top-down observation in combination with bottom-up NIR that can provide sufficient countrywide objective evidence for national follow-up activities. | Hwang, Youngseok; Schluter, Stephan; Choudhury, Tanupriya; Um, Jung-Sup | Kyungpook Natl Univ, Dept Climate Change, Daegu 41566, South Korea; Ulm Univ Appl Sci, Dept Math Nat & Econ Sci, D-89075 Ulm, Germany; Univ Petr & Energy Studies UPES, Sch Comp Sci, Dept Informat, Dehra Dun 248007, Uttarakhand, India; Kyungpook Natl Univ, Dept Geog, Daegu 41566, South Korea | Choudhury, Tanupriya/AAB-8947-2020; Um, Jung-Sup/F-5351-2018 | 57218585482; 55258366500; 57193140084; 35173565000 | poiu01234@knu.ac.kr;stephan.schlueter@thu.de;tanupriya@ddn.upes.ac.in;jsaeom@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 12 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.42 | 2025-07-30 | 6 | 7 | top-down; bottom-up; GOSAT XCO2; national inventory report; carbon footprint; MRV | ADMINISTRATIVE REGIONS; CO2 CONCENTRATION; ATMOSPHERIC CO2; OCO-2 XCO2; SWIR XCO2; CARBON; EMISSIONS; VERIFICATION; PERFORMANCE; ECOSYSTEMS | Bottom–up; Carbon footprint; GOSAT XCO<sub>2</sub>; MRV; National inventory report; Top–down | Europe; air mass; anthropogenic source; bottom-up approach; carbon dioxide; carbon emission; comparative study; emission inventory; GOSAT; greenhouse gas; integrated approach; Intergovernmental Panel on Climate Change; Kyoto Protocol; mitigation; satellite data; top-down approach; United Nations Framework Convention on Climate Change | English | 2021 | 2021-06 | 10.3390/su13126700 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Review | Current Knowledge of Medicinal Mushrooms Related to Anti-Oxidant Properties | Background: A renewed focus on medicinal mushrooms has brought forth a sustainable health dimension. Conventional health strategies are insufficiently integrated with sustainable health promotion. The health-promoting outcome of mushrooms has fascinated many groups during the past few years because of various primary and secondary metabolites in different cellular components. They contain many bioactive metabolites, including proteins (cytokines, ergothioneine), fibers, moisture, carbohydrates (uronic acid), folate, thiamine, ascorbic acid, vitamin D, calcium, potassium, polysaccharides (G. lucidum polysaccharides, alpha and beta glucans, and lentinan) polyketides, polyphenols (Protocatechuic acid, inonoblins A-vanillic acid, phelligridins D, E, and G, hydroxybenzoic acid, gallic acid, tannic acid, hispidine, gentisic acid, and tocopherol), nucleotides (adenosine, cordycepin), lovastatin, steroids, alkaloids, and sesquiterpenes. Objective: This study was conducted to gather information on the current knowledge of medicinal mushrooms, with respect to their antioxidant properties. Conclusions: The results indicated that mushrooms are a promising source of natural antioxidants. Of all mushrooms, the Ganoderma tsugae Murill exhibited an excellent antioxidant potential of 93.7-100% at 20 mg/mL. | Shaffique, Shifa; Kang, Sang-Mo; Kim, Ah-Yeong; Imran, Muhammad; Khan, Muhammad Aaqil; Lee, In-Jung | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Gyeonsangnam Do Agr Res & Extens Serv, Jinju 52733, South Korea | Imran, Muhammad/AFL-6590-2022; Kang, Sang-Mo/MBG-7823-2025; Lee, In-Jung/GLS-0432-2022; shaffique, shifa/KUC-7102-2024; Kim, Min/AAZ-9598-2021; Khan, Muhammad/ABB-9797-2021 | 57203898867; 56189696900; 56735250200; 58282433800; 57188585606; 16425830900 | Shifa.2021@knu.ac.kr;kmoya@hanmail.net;Kay0623@korea.kr;m.imran02@yahoo.com;aqil_bacha@yahoo.com;ijlee@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 14 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.89 | 2025-07-30 | 26 | 36 | medicinal mushrooms; antioxidant; metabolic disorder | RADICAL SCAVENGING ACTIVITIES; GANODERMA-LUCIDUM LINGZHI; ANTIMICROBIAL ACTIVITIES; CANTHARELLUS-CIBARIUS; METHANOLIC EXTRACTS; POLYSACCHARIDES; MECHANISMS; PRODUCTS; MYCELIUM; BULL. | Antioxidant; Medicinal mushrooms; Metabolic disorder | Basidiomycota; Ganoderma tsugae; antioxidant; knowledge; medicinal plant; metabolite; mushroom | English | 2021 | 2021-07 | 10.3390/su13147948 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Current Status and Future Directions of Deep Learning Applications for Safety Management in Construction | The application of deep learning (DL) for solving construction safety issues has achieved remarkable results in recent years that are superior to traditional methods. However, there is limited literature examining the links between DL and safety management and highlighting the contributions of DL studies in practice. Thus, this study aims to synthesize the current status of DL studies on construction safety and outline practical challenges and future opportunities. A total of 66 influential construction safety articles were analyzed from a technical aspect, such as convolutional neural networks, recurrent neural networks, and general neural networks. In the context of safety management, three main research directions were identified: utilizing DL for behaviors, physical conditions, and management issues. Overall, applying DL can resolve important safety challenges with high reliability; therein the CNN-based method and behaviors were the most applied directions with percentages of 75% and 67%, respectively. Based on the review findings, three future opportunities aiming to address the corresponding limitations were proposed: expanding a comprehensive dataset, improving technical restrictions due to occlusions, and identifying individuals who performed unsafe behaviors. This review thus may allow the identification of key areas and future directions where further research efforts need to be made with priority. | Pham, Hieu T. T.

| ○ | ○ | Article | Deriving Major Fire Risk Evaluation Items Utilizing Spatial Information Convergence Technology in Dense Areas of Small Obsolete Buildings | As small obsolete buildings are exposed to high fire risks, governments are trying to evaluate their fire risks and preferentially improve fire protection performance for high risk buildings, however, the evaluation manpower and time are insufficient compared to the rapidly increasing number of obsolete buildings. Therefore, this study aimed to derive major fire risk index (FRI) evaluation items as part of developing a platform to quickly and efficiently evaluate fire risks in dense areas of small obsolete buildings utilizing spatial information convergence technology. To this end, 20 preliminary evaluation items specifically tailored to dense areas of small obsolete buildings were derived through a field survey, investigation of FRI evaluation items from existing works, and expert pre-reviews. Based on the derived 20 preliminary items, an importance survey was conducted with a total of 181 fire safety experts including fire officers, university professors, researchers, industry experts, and fire insurers. As a result, a total of 12 major evaluation items (e.g., outdoor fire extinguisher, distance to 119 Safety Center, building structure, building cladding, illegal alterations, illegal parking, and liquefied natural gas cylinder) were derived. Results can help to evaluate the fast and efficient fire risks in dense areas of small obsolete buildings. | Lee, Hyung-Joo; Park, Sun-Woo; Roh, Seungjun; Ryu, Jung-Rim; Son, Byeung-Hun; Ryu, Seong-Ryong; Lee, Seung-youp; Park, Won-Jun | Ulsan Natl Inst Sci & Technol, Dept Urban & Environm Engn, Ulsan 44919, South Korea; Kumoh Natl Inst Technol, Dept Architectural Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Sch Architecture, Gumi 39177, South Korea; FMworks Inc, Daegu 41542, South Korea; Kyungpook Natl Univ, Sch Architecture, Daegu 41566, South Korea; Daegu Tech Univ, Dept Architecture, Daegu 42734, South Korea; Kangwon Natl Univ, Dept Architectural Engn, Samcheok 25913, South Korea | ; Roh, Seungjun/I-2523-2014 | 57205588372; 57340510500; 55421850500; 56712252100; 56909550800; 8423066400; 57339985700; 55552256200 | hyungjoolee@unist.ac.kr;psw0911@kumoh.ac.kr;roh@kumoh.ac.kr;ajaxrim@gmail.com;sonbh@ttc.ac.kr;archiryu@kumoh.ac.kr;syobi@kumoh.ac.kr;wjpark@kangwon.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 22 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.5 | 2025-07-30 | 2 | 7 | fire risk; fire risk index; evaluation item; small obsolete building; spatial information convergence technology | Evaluation item; Fire risk; Fire risk index; Small obsolete building; Spatial information convergence technology | building; information technology; liquefied natural gas; natural gas; risk assessment; safety | English | 2021 | 2021-11 | 10.3390/su132212593 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Development of Growth Model for Grafted Hot Pepper Seedlings as Affected by Air Temperature and Light Intensity | The objective of this study was to develop a growth model for grafted hot pepper seedlings as affected by air temperature and light intensity. After grafted union formation, the hot pepper seedlings were cultivated in various environmental factors in terms of four levels, mean daily air temperature (17, 22, 27, and 32 degrees C) and 3 levels of light intensity (150, 350, and 550 mu mol center dot m(-2)center dot s(-1)). The growth traits were measured 0, 7, 14, 21, and 28 days after grafted union formation (DAGU). The plant height was improved, and development of leaves enhanced by higher air temperature. The number of leaves was greatest under the combination of the high temperature and high light intensity, resulting in 39.0/plant at 28 DAGU. The leaf area and dry weight showed 491.9 cm(2)/plant and 2.68 g/plant, respectively, at 28 DAGU under 32 degrees C air temperature and 550 mu mol center dot m(-2)center dot s(-1) light intensity. The changes of dry weight were rapidly increased under the higher air temperature and light intensity as followed by analysis of the growth curve. The beta distribution model was developed, and the relative growth rate (RGR) was simulated by the model, the maximum RGR was predicted at 0.116 g center dot g center dot d(-1). The RGR showed 0.113, 0.127, and 0.109 g center dot g center dot d(-1) at 10, 20, and 30 degrees C air temperature, respectively, and RGR was improved by 12% by increasing the air temperature by 10 degrees C, without going over 25 degrees C ADT. Results indicated that the developed growth model might be applied to optimal environmental control for maximized RGR of production of grafted hot pepper seedlings. | Kwack, Yurina; An, Sewoong; Kim, Sung Kyeom | Yonam Coll, Div Smart Hort, Cheonan 31005, South Korea; Rural Dev Adm, Natl Inst Hort & Herbal Sci, Vegetable Res Div, Wonju 55365, South Korea; Kyungpook Natl Univ, Dept Hort Sci, Coll Agr Life Sci, Daegu 41566, South Korea | Kim, Sung Kyeom/AAD-9230-2019 | 18436934700; 57211403160; 50262290200 | greenrina@yonam.ac.kr;woong0911@korea.kr;skkim76@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 11 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.35 | 2025-07-30 | 5 | 6 | grafting; environmental control; beta distribution model; seedling; scion; rootstock | YOUNG TOMATO; PLANT-GROWTH; GREENHOUSE; CROP; PHOTOSYNTHESIS; HORTICULTURE; CUCUMBER; SYSTEM; IMPACT | Beta distribution model; Environmental control; Grafting; Rootstock; Scion; Seedling | Capsicum frutescens; air temperature; environmental factor; growth modeling; growth rate; light intensity; seedling | English | 2021 | 2021-06 | 10.3390/su13115895 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Development of Material Combination Model Considering Economics and Construction Efficiency for G-SEED Certification | The Korean government proposed a goal to reduce its greenhouse gas emissions by 37% compared to business-as-usual levels by 2030 and launched the Green Standard for Energy and Environmental Design (G-SEED) certification system. The certification requires meeting the required score and material selection with a secured economy and construction efficiency. However, most buildings only focus on obtaining the certification scores instead of choosing economical materials with high construction efficiency. This research focused on developing a material selection model that considers both the construction efficiency and economy of the materials and the acquisition of material and resource evaluation scores from the G-SEED certification. This research, therefore, analyzed actual data to automate the material selection and compare alternatives to using a genetic algorithm to obtain optimized alternatives. This model proposes an alternative to constructability and economy when the required score and material information is entered. When the model was applied to actual cases, the result revealed a reduction in construction costs of about 37% compared to the cost with the traditional methods. The material selection model from this research can benefit construction project owners in terms of cost reduction, designers in terms of structural design time, and constructors in terms of construction efficiency. | Jeon, Byung-Ju; Kim, Byung-Soo | Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea | Jeon, Byung-Ju/HHR-8314-2022 | 57222551267; 57013677400 | kyung7673@knu.ac.kr;bskim65@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 6 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.07 | 2025-07-30 | 1 | 1 | G-SEED; material selection; constructability; economic; genetic algorithms | MINIMUM-COST; LEED; SYSTEM; PERFORMANCE; SELECTION | Constructability; Economic; G-SEED; Genetic algorithms; Material selection | Korea; certification; efficiency measurement; emission control; environmental assessment; environmental economics; genetic algorithm; government; greenhouse gas; numerical model | English | 2021 | 2021-03 | 10.3390/su13063535 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Digital Certificate Verification Scheme for Smart Grid using Fog Computing (FONICA) | Smart Grid (SG) infrastructure is an energy network connected with computer networks for communication over the internet and intranets. The revolution of SGs has also introduced new avenues of security threats. Although Digital Certificates provide countermeasures, however, one of the issues that exist, is how to efficiently distribute certificate revocation information among Edge devices. The conventional mechanisms, including certificate revocation list (CRL) and online certificate status protocol (OCSP), are subjected to some limitations in energy efficient environments like SG infrastructure. To address the aforementioned challenges, this paper proposes a scheme incorporating the advantages and strengths of the fog computing. The fog node can be used for this purpose with much better resources closer to the edge. Keeping the resources closer to the edge strengthen the security aspect of smart grid networks. Similarly, a fog node can act as an intermediate Certification Authority (CA) (i.e., Fog Node as an Intermediate Certification Authority (FONICA)). Further, the proposed scheme has reduced storage, communication, processing overhead, and latency for certificate verification at edge devices. Furthermore, the proposed scheme reduces the attack surface, even if the attacker becomes a part of the network. | Mahmood, Shahid; Gohar, Moneeb; Choi, Jin-Ghoo; Koh, Seok-Joo; Alquhayz, Hani; Khan, Murad | Bahria Univ, Dept Comp Sci, Islamabad 44000, Pakistan; Yeungnam Univ, Dept Informat & Commun Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Majmaah Univ, Dept Comp Sci & Informat, Coll Sci Zulfi, Al Majmaah 11952, Saudi Arabia | ; ali, murad/J-6826-2015 | 7103283342; 36104105300; 7501394023; 8958394800; 55804201900; 56151971600 | 01-247181-024@student.bahria.edu.pk;mgohar.buic@bahria.edu.pk;jchoi@yu.ac.kr;sjkoh@knu.ac.kr;h.alquhayz@mu.edu.sa;mkhan@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 5 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 1.27 | 2025-07-30 | 7 | 22 | digital certificate revocation; smart grid (SG); Internet of Things; CRL; OCSP; edge devices; fog computing; IoT Devices; FONICA | SECURITY; INTERNET; PRIVACY | CRL; Digital certificate revocation; Edge devices; Fog computing; FONICA; Internet of Things; IoT Devices; OCSP; Smart grid (SG) | certification; communication; computer simulation; data processing; digitization; infrastructure; smart grid | English | 2021 | 2021-03 | 10.3390/su13052549 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effect of Different HVAC Control Strategies on Thermal Comfort and Adaptive Behavior in High-Rise Apartments | In the residential sector, householders play an active role in regulating the indoor climate via diverse control measures such as the operation of air-conditioners or windows. The main research question asked in this paper is whether control decisions made by householders are rational and effective in terms of achieving comfort and energy efficiency. Based on a field study in South Korea, this paper explores how a HVAC control strategy for high-rise apartment buildings can affect occupant comfort and adaptive behavior. Two different control strategies: (1) occupant control (OC), where occupants were allowed to freely operate the HVAC system and (2) comfort-zone control (CC), where the operation of the HVAC system was determined by the researcher, based on a pre-defined comfort zone, were applied to, and tested within the participating households in summer. The impact of the two control strategies on indoor thermal environments, thermal comfort, and occupant adaptive behavior were analyzed. We find that the CC strategy is more energy/comfort efficient than OC because: (1) comfort was be achieved at a higher indoor temperature, and (2) unnecessary control behaviors leading to cooling load increase can be minimized, which have major implications for energy consumption reduction in the residential sector. | Ryu, Jihye; Kim, Jungsoo | Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Univ Sydney, Sch Architecture Design & Planning, Sydney, NSW 2006, Australia | Kim, Jungsoo/GQB-1511-2022 | 56192651000; 57189969323 | ryou0407@knu.ac.kr;jungsoo.kim@sydney.edu.au; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 21 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.35 | 2025-07-30 | 3 | 5 | thermal comfort; HVAC system; adaptive behavior; residential buildings | ENERGY USE; NEUTRAL TEMPERATURE; OFFICE BUILDINGS; ENVIRONMENT; CLIMATE; ADAPTATION; OCCUPANTS; WINDOWS; MODEL; HOT | Adaptive behavior; HVAC system; Residential buildings; Thermal comfort | South Korea; air conditioning; building; cooling; energy efficiency; fuel consumption; indoor air; research work | English | 2021 | 2021-11 | 10.3390/su132111767 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Environmental and Cost Impact Assessment of Pavement Materials Using IBEES Method | For road pavements, hot-mix asphalt (HMA) and Portland cement concrete (PCC) are the materials most commonly used. In the selection of one of these materials, their economic performance and environmental performance are evaluated to determine which material exhibits excellent overall performance. However, no overall performance assessment exists in the construction community attributed to the lack of method providing easy-to-use and informative criteria for the decision-making process. Thus, in this paper, a new method that enables a comprehensive overall performance assessment is proposed, which is called Improved Building for Environmental and Economic Sustainability. After an eco-economic life-cycle assessment is performed, along with environmental performance and economic performance evaluation, the best-fit pavement material can be selected. This method has proven that the use of HMA for road pavements reduces the environmental impact by 27.1%P (i.e., percentage point), whereas the use of PCC reduces cost by 19.7%P. The existing Building for Environmental and Economic Sustainability (BEES) method shows that the performances of both HMA and PCC were over-assessed by 4.6%P and 7.4%P, respectively, since the environmental performance and economic performance cannot be computed quantitatively by incorporating the environmental and cost impact index into existing BEES model, the Improved BEES method accurately projects environmental performance and economic performance attained through the application of the environmental and cost impact index, hence, encouraging more informed decision. This method facilitates in articulating a quality decision making through the consideration of both the environmental performance and economic performance, hence reducing unnecessary costs generated from the trial and error due to the use of the existing method. Moreover, it promotes the development of a sustainable construction technology. | Park, Jin-Young; Kim, Byung-Soo; Lee, Dong-Eun | Kyungpook Natl Univ, Intelligent Construct Automat Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Civil Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea | 56923889700; 57013677400; 56605563300 | jinypark@knu.ac.kr;bskim65@knu.ac.kr;dolee@knu.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 4 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.5 | 2025-07-30 | 4 | 8 | LCA; LCCA; environmental impact; cost impact; sustainable construction | LIFE-CYCLE ASSESSMENT; CONSTRUCTION; FRAMEWORK; PROJECTS; MODEL | Cost impact; Environmental impact; LCA; LCCA; Sustainable construction | concrete; decision making; environmental impact assessment; pavement; performance assessment | English | 2021 | 2021-02 | 10.3390/su13041836 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Firefighting in Vulnerable Areas Based on the Connection between Fire Hydrants and Fire Brigade | A sufficient supply of water for firefighting is critical for effective responses to urban fires, thus reducing fire hazards. The aim of this study was the development of an analysis method for vulnerable areas with respect to firefighting activities that require the use of fire hydrants. In particular, a method was proposed for the determination of the operational range of firefighting activities based on the distribution of the fire hydrants and the roads that allow for the passage of firefighting vehicles. The proposed method, which employs a geographic information system (GIS), was applied to Buk-gu, Daegu City, South Korea. The research results revealed that the operational range of firefighting activities and vulnerable areas can be determined by studying the connection between the fire hydrant locations and the fire brigade in the analysis of the accessible areas. This study contributes to the development of GIS analysis methods for comprehensive vulnerability analyses of firefighting activities, including accessibility to fire hydrants. | Lee, Yoon Ha; Kim, Min Seok; Lee, Ji Soo | Hanyang Univ, Innovat Durable Bldg & Infrastruct Res Ctr, Ansan 15588, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungil Univ, Dept Fire Safety, Gyongsan 38428, South Korea | 57218699556; 59073001500; 56067528400 | dldbsgk123@naver.com;kms910601@gmail.com;jisoo@kiu.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 1 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.35 | 2025-07-30 | 6 | 8 | fire hydrant; fire brigade; geographic information system; vulnerable areas | WATER | Fire brigade; Fire hydrant; Geographic information system; Vulnerable areas | South Korea; Taegu [South Korea]; Taegu [Taegu (ADS)]; accessibility; freight transport; GIS; transport vehicle; urban area; vulnerability | English | 2021 | 2021-01 | 10.3390/su13010098 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

The proposed solutions consider eight cases of dispersion coefficients and velocities: both spatially dependent, both spatiotemporally dependent, both temporally dependent, spatiotemporally dependent dispersion coefficient with spatially dependent velocity, temporally dependent dispersion coefficient with constant velocity, both constant, spatially dependent dispersion coefficient with spatiotemporally dependent velocity, and constant dispersion coefficient with temporally dependent velocity. The spatial dependence is linear, while the temporal dependence may be exponential, asymptotical, or sinusoidal. An advection-dispersion equation with these variable coefficients was reduced to a non-homogeneous diffusion equation using the pertinent coordinate transform method. Then, solutions were obtained in an infinite medium using Green's function. The proposed analytical solutions were validated against existing analytical solutions or against numerical solutions when analytical solutions were unavailable. In this study, we showed that the proposed analytical solutions could be applied for various spatiotemporal patterns of both velocity and the dispersion coefficient, shedding light on feasibility of the proposed solution under highly transient flow in heterogeneous porous medium. | Sanskrityayn, Abhishek; Suk, Heejun; Chen, Jui-Sheng; Park, Eungyu | Post Grad Coll, Dept Math, Ghazipur 233001, Uttar Pradesh, India; Korea Inst Geosci & Mineral Resources, Daejeon 34132, South Korea; Natl Cent Univ, Grad Inst Appl Geol, Taoyuan 320, Taiwan; Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea | suk, heejun/A-3212-2015 | 57192307361; 23996203400; 7501893250; 23995577700 | abhi.bhu2008@gmail.com;sxh60@kigam.re.kr;jschen@geo.ncu.edu.tw;park.eungyu@gmail.com; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 14 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.7 | 2025-07-30 | 11 | 11 | analytical solution; Green's function; pertinent coordinate transformation; spatiotemporally varying variables | SCALE-DEPENDENT DISPERSION; DIFFUSION EQUATION; SEMIANALYTICAL SOLUTIONS; CONTAMINANT TRANSPORT; REACTION NETWORK; GROUNDWATER; VERIFICATION | Analytical solution; Green’s function; Pertinent coordinate transformation; Spatiotempo-rally varying variables | advection-diffusion equation; analytical method; coordinate; dispersion; porous medium; solute transport; transient flow | English | 2021 | 2021-07 | 10.3390/su13147796 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | How Switching Costs with Process Monitoring and Operational Integration Affect Sustainable Supplier Relationship | Building on sustainable supply chain management and operations strategy literature, our study seeks to identify structural relationships between switching cost and sustainable supplier relationships from a demand-side perspective. More specifically, this study looks at the impact of the switching cost on process monitoring, operation integration, and sustainable supplier relationships. To test the structural relationships in our research model, we used Manufacturing Productivity Survey data from Korea to conduct an empirical analysis based on 351 data that fit our study's purpose. The results show that the indirect effect of switching cost on sustainable supplier relationships through process monitoring and operational integration is positively valid. Additionally, the results emphasize that the social exchange theory can be explained in the perspective of the switching cost. | Lee, Sunghee; Park, Jinsoo | Hoseo Univ, Dept Business Adm, 12 Hoseodae Gil, Cheonan Si 31066, South Korea; Kyungpook Natl Univ, Sch Business Adm, Daegu 41566, South Korea | 57203597426; 57207622135 | shlee16@hoseo.edu;hgjdie@gmail.com; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 24 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0 | 2025-07-30 | 0 | 0 | switching cost; process monitoring; operational integration; sustainable supplier relationship | CHAIN MANAGEMENT; ORGANIZATION; TECHNOLOGY; SELECTION; BEHAVIOR; DRIVERS; IMPACT; GREEN; MODEL; FOCUS | Operational integration; Process monitoring; Sustainable supplier relationship; Switching cost | Korea; cost analysis; environmental monitoring; manufacturing; social theory; supply chain management; sustainability; sustainable development | English | 2021 | 2021-12 | 10.3390/su132413716 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Human, Technical, and Organizational Drivers Affecting Sustainability of Content Firms through Management and Innovation Capability during COVID-19 | Individuals and businesses engage in a number of activities in the digital environment. During unexpected circumstances, such as COVID-19, many people used the internet for purposes such as education, work, and entertainment. This has led to a rapid growth in the content industry. Thus, studies of the sustainability and success of content companies are essential. Few empirical studies focus on these aspects of content companies, particularly concentrating on the importance of management and innovation capability. This study examines the roles of management and innovation capabilities and the human, technical, and organizational factors that affect these capabilities. This, in turn, positively affects the sustainability and success of content companies. The proposed research model includes content development ability and leadership as a human factor, technical support and information technology (IT) infrastructure as a technical factor, and top management and financial support as an organizational factor. A total of 255 responses were collected from upper management-level employees at various firms in the content industry. Covariance-based structural equation modeling was used with Amos 22.0. The results indicated that all proposed hypotheses were supported with the exception of the hypothesis that tests the relationship between content development and management capability. The study findings provide information necessary for future sustainability and success of content companies. | Park, Hyunsun; Kim, Sanghyun; Choi, Moonjong; Choi, Jaesung | Kyungpook Natl Univ, Sch Business Adm, Daegu 41566, South Korea; Daegu Ctr Creat Econ & Innovat, 51 Hoam Ro, Daegu 41585, South Korea; Sunmoon Univ, Dept Comp Sci & Engn, Asan 31460, South Korea | 55533334100; 58950708200; 56323852100; 55722515100 | pullip83@hanmail.net;ksh@knu.ac.kr;mjchoi0@gmail.com;jschoi@sunmoon.ac.kr; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 12 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.14 | 2025-07-30 | 4 | 4 | human factor; technical factor; organizational factor; management capability; innovation capability; sustainability of content business | INFORMATION-TECHNOLOGY; SUCCESS FACTORS; COMPETITIVE ADVANTAGE; DETERMINANTS; INFRASTRUCTURE; PATTERNS; STRATEGY; ASSIMILATION; FLEXIBILITY; PERFORMANCE | Human factor; Innovation capability; Management capability; Organizational factor; Sustainability of content business; Technical factor | covariance analysis; growth; innovation; leadership; numerical model; software; sustainability | English | 2021 | 2021-06 | 10.3390/su13126661 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Indoor Nanoparticle Characterization in Construction Waste Recycling Companies over Time | Building activity is a significant source of atmospheric contamination by ultrafine dust. Cognizant of this fact, those active in the use and recycling of construction materials must be aware of the risks associated with exposure to nanoparticles (NPs) and ultra-fine particles (UFPs), as well as the associated health impacts. This work analyzed NPs and UFPs generated in a small building-material recycling company using high-resolution electron microscopes and X-ray Diffraction. A self-made passive sampler (LSPS) that can obtain particulate samples without physical and morphological changes, especially where there is a suspension of particulate material, was used in this study. A total of 96 particulate samples, using the LSPS for three months in four seasons, were collected during the study. Thus, the dry deposition of the particles, which are considered highly harmful to human health, was found in each of the four seasons of the year. It is suggested that for future research, the toxicological evaluations of the particulates in the construction industry should be investigated through the consideration of measures to control and mitigate the health risks of workers regarding exposure to NPs and UFPs. | Pinto, Diana; Neckel, Alcindo; Dotto, Guilherme L.; Adelodun, Bashir | Univ Costa, CUC, Dept Civil & Environm, Barranquilla 080002, Colombia; IMED, Fac Merid, BR-99070220 Passo Fundo, RS, Brazil; Fed Univ Santa Maria UFSM, Chem Engn Dept, BR-97105900 Santa Maria, RS, Brazil; Univ Ilorin, Dept Agr & Biosyst Engn, Ilorin 240103, Nigeria; Kyungpook Natl Univ, Dept Agr Civil Engn, Daegu 41566, South Korea | Pinto, Diana/D-5446-2015; Dotto, Guilherme/I-8271-2015; Neckel, Alcindo/AAN-4623-2020; Adelodun, Bashir/O-2941-2018 | 57195677095; 56973887600; 26639244700; 57193774482 | dpinto3@cuc.edu.co;alcindo.neckel@imed.edu.br;guilherme_dotto@yahoo.com.br;adelodun.b@unilorin.edu.ng; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 24 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.14 | 2025-07-30 | 2 | 2 | air pollution; construction waste recycling; nanoparticles; human health | HAZARDOUS ELEMENTS; SANTA-CATARINA; COAL; PARTICLES; POLLUTION; GENOTOXICITY; ENVIRONMENT; HEALTH; MATTER; SOILS | Air pollution; Construction waste recycling; Human health; Nanoparticles | construction industry; dry deposition; electron microscopy; nanoparticle; recycling; waste; X-ray diffraction | English | 2021 | 2021-12 | 10.3390/su132414071 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Multi-Objective Particle Swarm Optimization-Based Decision Support Model for Integrating Renewable Energy Systems in a Korean Campus Building | Renewable energy systems are an alternative to existing systems to achieve energy savings and carbon dioxide emission reduction. Subsequently, preventing the reckless installation of renewable energy systems and formulating appropriate energy policies, including sales strategies, is critical. Thus, this study aimed to achieve energy reduction through optimal selection of the capacity and lifetime of solar thermal (ST) and ground source heat pump (GSHP) systems that can reduce the thermal energy of buildings including the most widely used photovoltaic (PV) systems. Additionally, this study explored decision-making for optimal PV, ST, and GSHP installation considering economic and environmental factors such as energy sales strategy and electricity price according to energy policies. Therefore, an optimization model based on multi-objective particle swarm optimization was proposed to maximize lifecycle cost and energy savings based on the target energy savings according to PV capacity. Furthermore, the proposed model was verified through a case study on campus buildings in Korea: PV 60 kW and ST 32 m(2) GSHP10 kW with a lifetime of 50 years were found to be the optimal combination and capacity. The proposed model guarantees economic optimization, is scalable, and can be used as a decision-making model to install renewable energy systems in buildings worldwide. | Sim, Minjeong; Suh, Dongjun; Otto, Marc-Oliver | Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju 37224, South Korea; Ulm Univ Appl Sci, Dept Math Nat & Econ Sci, Prittwitzstr 10, D-89075 Ulm, Germany | 57226480124; 36613529600; 57217105369 | smj658@knu.ac.kr;dongjunsuh@knu.ac.kr;Marc-Oliver.Otto@thu.de; | SUSTAINABILITY | SUSTAINABILITY-BASEL | 2071-1050 | 13 | 15 | SCIE;SSCI | ENVIRONMENTAL SCIENCES;ENVIRONMENTAL STUDIES;GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY | 2021 | 3.889 | 44.1 | 0.92 | 2025-07-30 | 12 | 14 | renewable energy systems; multi-objective particle swarm optimization; retrofit; lifecycle cost | CARBON EMISSIONS; DESIGN; STRATEGIES; MANAGEMENT; EFFICIENCY; ZERO | Lifecy-cle cost; Multi-objective particle swarm optimization; Renewable energy systems; Retrofit | Korea; alternative energy; building; carbon dioxide; decision support system; emission control; multiobjective programming; optimization; photovoltaic system | English | 2021 | 2021-08 | 10.3390/su13158660 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
