| ○ | ○ | Article | KR Sri Preethaa1,2, N. Yuvaraj1,2, Gitanjali Wadhwa2, Sujeen Song3, Se-Woon Choi4 and Bubryur Kim1 | The emergence of high-rise buildings has necessitated frequent structural health monitoring and maintenance for safety reasons. Wind causes damage and structural changes on tall structures; thus, safe structures should be designed. The pressure developed on tall buildings has been utilized in previous research studies to assess the impacts of wind on structures. The wind tunnel test is a primary research method commonly used to quantify the aerodynamic characteristics of high-rise buildings. Wind pressure is measured by placing pressure sensor taps at different locations on tall buildings, and the collected data are used for analysis. However, sensors may malfunction and produce erroneous data; these data losses make it difficult to analyze aerodynamic properties. Therefore, it is essential to generate missing data relative to the original data obtained from neighboring pressure sensor taps at various intervals. This study proposes a deep learning-based, deep convolutional generative adversarial network (DCGAN) to restore missing data associated with faulty pressure sensors installed on high-rise buildings. The performance of the proposed DCGAN is validated by using a standard imputation model known as the generative adversarial imputation network (GAIN). The average mean-square error (AMSE) and average R-squared (ARSE) are used as performance metrics. The calculated ARSE values by DCGAN on the building model's front, backside, left, and right sides are 0.970, 0.972, 0.984 and 0.978, respectively. The AMSE produced by DCGAN on four sides of the building model is 0.008, 0.010, 0.015 and 0.014. The average standard deviation of the actual measures of the pressure sensors on four sides of the model were 0.1738, 0.1758, 0.2234 and 0.2278. The average standard deviation of the pressure values generated by the proposed DCGAN imputation model was closer to that of the measured actual with values of 0.1736,0.1746,0.2191, and 0.2239 on four sides, respectively. In comparison, the standard deviation of the values predicted by GAIN are 0.1726,0.1735,0.2161, and 0.2209, which is far from actual values. The results demonstrate that DCGAN model fits better for data imputation than the GAIN model with improved accuracy and fewer error rates. Additionally, the DCGAN is utilized to estimate the wind pressure in regions of buildings where no pressure sensor taps are available; the model yielded greater prediction accuracy than GAIN. | Preethaa, K.

| ○ | ○ | Article | Predicting the lateral displacement of tall buildings using an LSTM-based deep learning approach | Structural health monitoring is used to ensure the well-being of civil structures by detecting damage and estimating deterioration. Wind flow applies external loads to high-rise buildings, with the horizontal force component of the wind causing structural displacements in high-rise buildings. This study proposes a deep learning-based predictive model for measuring lateral displacement response in high-rise buildings. The proposed long short-term memory model functions as a sequence generator to generate displacements on building floors depending on the displacement statistics collected on the top floor. The model was trained with wind-induced displacement data for the top floor of a high-rise building as input. The outcomes demonstrate that the model can forecast wind-induced displacement on the remaining floors of a building. Further, displacement was predicted for each floor of the high-rise buildings at wind flow angles of 0 & DEG; and 45 & DEG;. The proposed model accurately predicted a high-rise building model's story drift and lateral displacement. The outcomes of this proposed work are anticipated to serve as a guide for assessing the overall lateral displacement of high-rise buildings. | Kim, Bubryur; Preethaa, K. R.

| ○ | ○ | Article | Major Decisive Factors of Tropical Cyclone Risk in the Republic of Korea: Intensity, Track, and Extratropical Transition | After the catastrophic damage caused by the extratropical transitioned North Atlantic hurricane Sandy (2012), the decaying stage of a tropical cyclone (TC) have received more attention. TC undergoing extratropical transition (ET) in mid-latitudes may become hazardous with torrential rain and violent wind over a vast area. In this study, a decision tree analysis was applied to evaluate the relative importance of TC parameters such as intensity category, entry location, and distance from coastlines, in determining damage occurrence. All 123 landfalling TCs in the Republic of Korea (hereafter Korea) during 1979-2015 were analyzed. The results reveal that intense TCs (severe tropical storms and typhoons) incur damages regardless of entry location and distance from coastlines. TCs with tropical storm intensity are expected to incur damages only when they approach the southwest of the Korean Peninsula. Weak TC with maximum wind speeds smaller than 17 m s(-1) does not have the potential to incur damages unless the TC was undergoing extratropical transition (ET) during landfall in Korea. ET storms that make a landfall approaching 1.22 degrees (similar to 130 km) to the coastline cause substantial damages especially in the west coast and capital area of Korea. The present results suggest that accurate forecasting that also considers ET, and not only intensity and track, is essential for successful disaster risk mitigation. | Nam, Chaehyeon Chelsea; Park, Doo-Sun R.; Ho, Chang-Hoi | Colorado State Univ, Dept Atmospher Sci, Ft Collins, CO USA; Kyungpook Natl Univ, Dept Earth Sci Educ, Daegu, South Korea; Seoul Natl Univ, Sch Earth & Environm Sci, Seoul, South Korea | Ho, Chang-Hoi/H-8354-2015; Park, Doo-Sun/U-9448-2019 | 56662775300; 37117659000; 7404653593 | dsrpark@knu.ac.kr; | ASIA-PACIFIC JOURNAL OF ATMOSPHERIC SCIENCES | ASIA-PAC J ATMOS SCI | 1976-7633 | 1976-7951 | 59 | 3 | SCIE | METEOROLOGY & ATMOSPHERIC SCIENCES | 2023 | 2.2 | 65.9 | 0.49 | 2025-06-25 | 4 | 3 | Tropical cyclone; Extratropical transition; Damage; Risk; Decision tree | DAMAGES; IMPACT; LEVEL; FLOW | Damage; Decision tree; Extratropical transition; Risk; Tropical cyclone | Atlantic Ocean; Atlantic Ocean (North); Korea; South Korea; coast; hurricane; natural disaster; storm; tropical cyclone | English | 2023 | 2023-06 | 10.1007/s13143-023-00318-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Relative abundance of mammals and estimation of minimum trapping effort using camera traps in Jangsudae, Seoraksan National Park | In Jangsudae of Seoraksan National Park, South Korea, 14 mammal species have been listed, including ten medium- and large-sized species; additionally, this region is an important habitat for the endangered long-tailed goral (Naemorhedus caudatus). In this study, a camera trap survey was conducted over 103 monitoring days at 18 sites in Jangsudae to evaluate the minimum trapping effort (MTE) needed to detect the ten listed mammal species. The most photographed species were the longtailed goral, wild boar (Sus scrofa), and Asian badger (Meles leucurus), accounting for 77.1% (n = 366) of the total independent photographs. Long-tailed goral, the most frequently captured mammal species (44.8%), was captured at 17 camera sites (relative abundance index = 206.8). According to the rarefaction analysis, 1840 camera days (102.2 monitoring days at 18 camera sites) were required to photograph all ten resident species. Moreover, at least 1010 and 664 camera days were required to detect 95% and 90% of the ten residential species, respectively. MTE was evaluated in summer when wild species were highly detectable owing to their high activity. Future studies should evaluate MTE through one-year long-term monitoring that includes all four seasons, and compare the results with those of this study. | Lim, Sang Jin; Han, So Hyeon; Kim, Ki Yoon; Hong, Sungwon; Park, Yung Chul | Kangwon Natl Univ, Inst Forest Sci, Chunchon, South Korea; Kangwon Natl Univ, Chunchon, South Korea; Kyungpook Natl Univ, Sangju, South Korea | 57193349673; 58527856300; 57202229085; 56431586600; 55494376600 | parky@kangwon.ac.kr; | MAMMAL STUDY | MAMM STUDY | 1343-4152 | 1348-6160 | 48 | 3 | SCIE | ZOOLOGY | 2023 | 0.8 | 66.0 | 1.21 | 2025-06-25 | 4 | 4 | camera trapping; large terrestrial mammals; long-tailed goral; rarefaction analysis; species richness | INDEXES; FOREST; ECOLOGY; EXAMPLE; TIGERS; RATES | camera trapping; large terrestrial mammals; long-tailed goral; rarefaction analysis; species richness | English | 2023 | 2023-07 | 10.3106/ms2022-0035 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | A systematic literature review on the decarbonisation of the building sector-a case for Nigeria | The buildings sector is responsible for over 36% of total global end-use energy utilization and nearly 40% of the total indirect and direct carbon emissions. Low-carbon or zero-energy buildings remain the only option to lessen the sector's energy consumption and CO2 emissions. The current systematic study examines low-carbon buildings under deep decarbonization scenarios in selected global south regions from 2010 to 2021. The study was channelled by the PRISMA ("Preferred Reporting Items for Systematic reviews and Meta-Analyses") review process, which identified 29 related articles from Scopus, Web of Science., and Google Scholar databases. The identified critical drivers of emissions were population, gross domestic product, dwelling characteristics, and urbanization. The dwelling characteristics contributed about 12% and 27% to the total CO2 emissions in the selected regions. The population varies between 23% and 27% across the areas. Specific findings were made for inclusion in the Nigeria model while the general results were observed and further studies proposed. Total investment from the private and public sectors was identified as key to achieving the transition process of decarbonization in the building sector. | Abam, Fidelis Ibiang; Nwachukwu, Chinedum Oscar; Emodi, Nnaemeka Vincent; Okereke, Chukwumerije; Diemuodeke, Ogheneruona E.; Owolabi, Abdulhameed Babatunde; Owebor, Kesiena; Suh, Dongjun; Huh, Jeung-Soo | Univ Calabar, Dept Mech Engn, Energy Exergy & Environm Res Grp EEERG, Calabar, Cross River, Nigeria; Univ Port Harcourt, Fac Engn, Dept Mech Engn, Energy & Thermofluid Res Grp, Port Harcourt, Rivers, Nigeria; Univ Queensland, Tasmanian Sch Business & Econ, Brisbane, Australia; Alex Ekueme Fed Univ, Ctr Climate Change & Dev, Ndufu, Ebonyi, Nigeria; Univ Bristol, Sch Policy Studies, Bristol, England; Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Sangju, South Korea; Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju, South Korea; Delta State Univ, Dept Mech Engn, Abraka, Delta, Nigeria; Kyungpook Natl Univ, Dept Energy Convergence & Climate Change, Daegu, South Korea | Owebor, Kesiena/IZE-1686-2023; OWEBOR, KESIENA/IZE-1686-2023; Abam, Fidelis/Q-9600-2019; Emodi, Nnaemeka/H-8553-2019; Diemuodeke, Ogheneruona/AAJ-4746-2020 | 34767767800; 57202094234; 56481633600; 33568129300; 36149855400; 57192210107; 57202302539; 36613529600; 7102258915 | jshuh@knu.ac.kr; | FRONTIERS IN ENERGY RESEARCH | FRONT ENERGY RES | 2296-598X | 11 | SCIE | ENERGY & FUELS | 2023 | 2.6 | 66.4 | 0.75 | 2025-06-25 | 8 | 8 | residential sector; decarbonization; Nigeria; building sector; global south | DEEP DECARBONIZATION PATHWAYS; HOUSEHOLD ENERGY USE; RESIDENTIAL SECTOR; MODEL PROJECTIONS; DEMAND; POLICY; CONSUMPTION; ADAPTATION; EFFICIENCY | building sector; decarbonization; global south; Nigeria; residential sector | Carbon; Carbon dioxide; Decarbonization; Housing; Investments; Zero energy buildings; Buildings sector; Carbon emissions; CO 2 emission; Decarbonisation; Direct carbons; End-uses; Global south; Nigeria; Residential sectors; Systematic literature review; Energy utilization | English | 2023 | 2023-09-19 | 10.3389/fenrg.2023.1253825 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Assessing the viability of a grid-connected PV power plant in Mubi, Adamawa State, Nigeria | This paper is based on a techno-economic analysis and the environmental impact of a proposed 1 MW solar photovoltaic (PV) power plant at the main campus of the Federal Polytechnic Mubi (FPM) in north-eastern Nigeria. A photovoltaic power plant converts solar radiation into electricity that can be used as a source of electrical power to meet the daily energy requirements of homes, equipment, and all tertiary institutions. RETScreen Expert software was used to evaluate the techno-economic and environmental sustainability of installing a grid-connected PV power plant. The research results revealed that with an annual solar radiation of 5.74 kWh/m(2)/day, the maximum annual energy production was estimated to be 1,550.98 MWh. It was discovered that the maximum energy production in March was 146.89 MWh. The project's profitability and economic sustainability were determined with a good internal rate of return (IRR) of 11.9% and a positive net present value (NPV) of $681,164. The proposed PV power plant has a simple payback period of 11.4 years. The maximum greenhouse gas (GHG) emission reduction is 670.9 tCO(2), equivalent to 61.7 ha of forest-absorbing carbon emissions. | Luqman, Raji; Issa, Abdul-Jeleel Kehinde; Owolabi, Abdulhameed Babatunde; Yakub, Abdulfatai Olatunji; Same, Noel Ngando; Yasin, Navid; Kavgic, Miroslava; Suh, Dongjun; Huh, Jeung-Soo | Fed Polytech Mubi, Sch Engn, Dept Mech Engn, Mubi, Nigeria; Fed Polytech Mubi, Ctr Entrepreneurship Dev, Mubi, Nigeria; Kyungpook Natl Univ, Reg Leading Res Ctr Smart Energy Syst, Sangju, South Korea; Kyungpook Natl Univ, Dept Convergence & Fus Syst Engn, Sangju, South Korea; Canadian Univ Dubai, Dept Entrepreneurship & Creat Ind, Dubai, U Arab Emirates; Univ Ottawa, Civil Engn Dept, Ottawa, ON, Canada; Kyungpook Natl Univ, Dept Energy Convergence & Climate Change, Daegu, South Korea | Kavgic, Miroslava/HKP-2262-2023 | 58479611100; 58479292300; 57192210107; 57894905100; 57895613600; 55625375000; 23995316100; 36613529600; 7102258915 | dongjunsuh@knu.ac.kr; | FRONTIERS IN ENERGY RESEARCH | FRONT ENERGY RES | 2296-598X | 11 | SCIE | ENERGY & FUELS | 2023 | 2.6 | 66.4 | 0.32 | 2025-06-25 | 3 | 3 | solar photovoltaic; RETScreen expert; solar energy; renewable energy; techno-economic; sustainability | SUSTAINABLE ENERGY; SOLAR-ENERGY; PERFORMANCE; SYSTEMS; TECHNOLOGIES; FEASIBILITY; GENERATION; SI | renewable energy; RETScreen expert; solar energy; solar photovoltaic; sustainability; techno-economic | Earnings; Economic analysis; Emission control; Forestry; Gas emissions; Greenhouse gases; Investments; Solar concentrators; Solar power generation; Solar radiation; Sustainable development; Economic sustainability; Grid-connected; Nigeria; Photovoltaic power plant; Renewable energies; RETScreen; Retscreen expert; Solar photovoltaics; Techno-Economic analysis; Techno-economics; Solar energy | English | 2023 | 2023-06-23 | 10.3389/fenrg.2023.1205646 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Effect of salt stress on the biomass productivity and potential bioenergy feedstock of Graesiella emersonii KNUA204 isolated from Ulleungdo Island, South Korea | Microalgae are versatile, profitable, and promising sources of bioenergy and high-value products, having various applications in the biotechnology industry. Herein, G. emersonii KNUA204 was isolated from Ulleungdo Island, South Korea, and exposed to stressors, i.e., MgCl2 (75 and 150 mM) and NaCl (200 and 400 mM), to investigate improvement in its biomass productivity and feasibility of the application of biomass. Treatment with mild MgCl2 (75 mM) afforded the highest specific growth rate (mu = 0.13 d(-1)), dry cell weight (3 g L-1), and total carbohydrate content (29.87%). Although all salt treatments decreased chlorophyll and carotenoid contents, treatment with high NaCl concentration (400 mM) afforded the highest zeaxanthin content (0.3 mg g(-1)). The proximate and ultimate analyses of biomass following treatment with 150 mM MgCl2 revealed 93.85% volatile matter and 22.55 MJ kg(-1) calorific value, respectively, indicating that Graesiella emersonii KNUA204 can be potentially used as bioenergy feedstock. The biodiesel quality was established based on the fatty acid methyl ester profiles, and MgCl2 treatment increased the cetane number more than the control. Therefore, the treatment of G. emersonii KNUA204 with MgCl2 during cultivation could provide a microalgae-based bioenergy feedstock with high productivity. | Do, Jeong-Mi; Yeo, Hee-Tae; Suh, Ho Seong; Yoon, Ho-Sung | Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat Biores Grp, Daegu, South Korea; Kyungpook Natl Univ, Adv Bioresource Res Ctr, Daegu, South Korea | 57208562245; 57224478334; 58139501200; 7402990205 | hsy@knu.ac.kr; | FRONTIERS IN ENERGY RESEARCH | FRONT ENERGY RES | 2296-598X | 11 | SCIE | ENERGY & FUELS | 2023 | 2.6 | 66.4 | 0.54 | 2025-06-25 | 5 | 5 | indigenous microalgae; salt stress; bioenergy; biomass productivity; pigment | FATTY-ACID-COMPOSITION; SALINITY STRESS; BIODIESEL PRODUCTION; ENHANCED PRODUCTION; FUEL PROPERTIES; DUNALIELLA SP; MICROALGAE; GROWTH; ACCUMULATION; TOLERANCE | bioenergy; biomass productivity; indigenous microalgae; pigment; salt stress | Biodiesel; Biomass; Fatty acids; Feedstocks; Magnesium compounds; Microorganisms; Sodium chloride; Bio-energy; Biomass potential; Biomass productivity; Biotechnology industry; Exposed to; Indigenous microalga; Micro-algae; Salt stresss; South Korea; Specific growth rate; Microalgae | English | 2023 | 2023-02-16 | 10.3389/fenrg.2023.1056835 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Ideal factorization in strongly discrete independent rings of Krull type | Let D be an integral domain and w be the so-called w-operation on D. In this paper, we define the notion of w-ZPUI domains which is a natural generalization of ZPUI domains introduced by Olberding in 2000. We say that D is a w-ZPUI domain if every nonzero proper w-ideal I of D can be written as I = (JP(1) middot middot middot P-n)w for some w-invertible ideal J of D and {P-1, ... , P-n} is a nonempty collection of pairwise w-comaximal prime w-ideals of D. Then, among other things, we show that D is a w-ZPUI domain if and only if the polynomial ring D[X] is a w-ZPUI domain, if and only if D is a strongly discrete independent ring of Krull type. We construct three types of new w-ZPUI domains from an old one by A + X B[X]-construction, pullback, and D[{X-i, Y-i, U-i, V-i}]/({XiVi-Y(i)Ui(}))-domains. We also show that given an abelian group G, there is a ZPUI domain with ideal class group G but not a Dedekind domain. Finally, we introduce and study the notion of w-ISP domains as a generalization of w-ZPUI domains. | Chang, Gyu Whan; Choi, Hyun Seung | Incheon Natl Univ, Dept Math Educ, Incheon 22012, South Korea; Kyungpook Natl Univ, Dept Math Educ, Daegu 41566, South Korea | 7402308842; 57211287845 | whan@inu.ac.kr;hchoi21@knu.ac.kr; | JOURNAL OF ALGEBRA AND ITS APPLICATIONS | J ALGEBRA APPL | 0219-4988 | 1793-6829 | 22 | 02 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2023 | 0.5 | 66.4 | 0.4 | 2025-06-25 | 1 | 1 | (w-)ZPUI domains; PvMDs; strongly discrete independent rings of Krull type; (w-)ISP domains | EVERY ABELIAN-GROUP; DOMAINS; PRIME | (w-)ISP domains; (w-)ZPUI domains; PvMDs; strongly discrete independent rings of Krull type | English | 2023 | 2023-02 | 10.1142/s0219498823500457 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

An element [x*, x(1),..., x(n)] is an element of Pi(E) is called a numerical radius point of T is an element of L(E-n : E) if |x*(T(x(1),..., x(n)))| = v(T), where v(T) is the numerical radius of T. Nradius(T) denotes the set of all numerical radius points of T. In this paper we classify Nradius(T) for every T is an element of L((2)l(2)(1) : l(1)(2)) in connection with Norm(T), where Norm(T) denotes the set of all norming points of T. | Kim, Sung Guen | Kyungpook Natl Univ, Dept Math, Daegu 702701, South Korea | 34769667700 | sgk317@knu.ac.kr; | RAD HRVATSKE AKADEMIJE ZNANOSTI I UMJETNOSTI-MATEMATICKE ZNANOSTI | RAD HRVAT AKAD ZNAN | 1849-2215 | 27 | 555 | ESCI | MATHEMATICS | 2023 | 0.5 | 66.4 | 0 | 2025-06-25 | 0 | 0 | Numerical radius; numerical radius attaining bilinear forms; numerical radius points | NORM; POLYNOMIALS | Numerical radius; numerical radius attaining bilinear forms; numerical radius points | English | 2023 | 2023 | 10.21857/y7v64tvgly | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | Article | Acute decompensated heart failure after transcatheter aortic valve implantation: A case report | Key Clinical MessageTranscatheter aortic valve implantation (TVAI) is a widely used treatment modality for severe aortic stenosis. The complication rates of the procedure have gradually decreased over time, owing to the improvements in procedural skills and development of TVAI devices. However, several rare but serious complications can still occur after TAVI. We recently encountered acute decompensated heart failure as a rare and fatal complication of TAVI and would like to share our experience. | Kim, Hong Nyun; Yang, Dong Heon; Park, Bo Eun | Kyungpook Natl Univ Hosp, Dept Internal Med, Div Cardiol, Daegu, South Korea; Kyungpook Natl Univ, Dept Internal Med, Div Cardiol, Chilgok Hosp, Daegu, South Korea; Kyungpook Natl Univ, Dept Internal Med, Sch Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Internal Med, Div Cardiol, 130, Dongdeok Ro, Daegu 41944, South Korea | ddyang@knu.ac.kr; | CLINICAL CASE REPORTS | CLIN CASE REP | 2050-0904 | 11 | 7 | ESCI | MEDICINE, GENERAL & INTERNAL | 2023 | 0.6 | 67.0 | 2 | acute decompensated heart failure; left ventricular stunning; stress-induced cardiomyopathy; suicide left ventricle; transcatheter aortic valve implantation | REPLACEMENT; CARDIOMYOPATHY | English | 2023 | 2023-07 | 10.1002/ccr3.7597 | 바로가기 | 바로가기 | 바로가기 |
