| ○ | ○ | Article | Edge Computing-Based Self-Organized Device Network for Awareness Activities of Daily Living in the Home | Activities of daily living (ADL) are important indicators for awareness of brain health in the elderly, and hospitals use ADL as a standard test for diagnosing chronic brain diseases such as dementia. However, since it is difficult to judge real-life ADL in hospitals, doctors typically predict ADL ability through interviews with patients or accompanying caregivers. Recently, many studies have attempted to diagnose accurate brain health by collecting and analyzing the real-life ADL of patients in their living environments. However, most of these were conducted by constructing and implementing expensive smart homes with the concept of centralized computing, and ADL data were collected from simple data about patients' home appliance usage and the surrounding environment. Despite the high cost of building a smart home, the collected ADL data are inadequate for predicting accurate brain health. In this study, we developed and used three types of portable devices (wearable, tag, and stationary) that can be easily installed and operated in typical existing houses. We propose a self-organized device network structure based on edge computing that can perform user perception, location perception, and behavioral perception simultaneously. This approach enables us to collect user activity data, analyze ADL in real-time to determine if the user's behavior was successful or abnormal, and record the physical ability of the user to move between fixed spaces. The characteristics of this proposed system enable us to distinguish patients from other family members and provide real-time notifications after a forgetful or mistaken action. We implemented devices that constitute the edge network of the smart home scenario and evaluated the performance of this system to verify its usefulness. | Keum, Seong Su; Park, Yu Jin; Kang, Soon Ju | Kyungpook Natl Univ, Coll IT Engn, Sch Elect Engn, 80 Daehakro, Daegu 702701, South Korea; Kyungpook Natl Univ, Ctr Self Organizing Software Platform, 80 Daehakro, Daegu 702701, South Korea | 57216412653; 55494454700; 55666313900 | kss6609@naver.com;ilbsyjp@gmail.com;sjkang@ee.knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.39 | 2025-06-25 | 5 | 6 | activities of daily living; smart home; edge computing; ambient assisted living; IoT | ACTIVITY RECOGNITION; SMART HOMES | Activities of daily living; Ambient assisted living; Edge computing; IoT; Smart home | English | 2020 | 2020-04 | 10.3390/app10072475 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Effect of Cyclic Loading Frequency on Liquefaction Prediction of Sand | Featured Application This paper concluded that liquefaction resistance of sand increases with the increasing of cyclic loading frequency based on a series of cyclic direct simple shear tests. In practical terms, compared to the frequency of a seismic excitation, a lower loading frequency used in laboratory tests has an under-estimation of the liquefaction resistance of sand, which could render designs costly. Furthermore, the results from this study could be used in the calibration of numerical study on the liquefaction prediction of sand. The frequency of ground motions during earthquakes is typically in the order of a few hertz. As the earthquake-induced liquefaction of soils is widely assessed by performing laboratory tests, it is necessary to consider various loading frequencies generated by real earthquakes. The effect of loading frequency has been studied by cyclic triaxial tests; however, it has rarely been investigated by cyclic direct simple shear tests, which are more similar to the cyclic loading conditions associated with earthquakes. In this study, a series of cyclic direct simple shear tests were performed on clean sand with a relative density (D-r) of 40% (loose sand) and 80% (dense sand), obtained from Nakdong River. The parameters considered are the initial vertical effective stresses (sigma(v0)' = 50, 100, and 200 kPa) and the loading frequencies (f= 0.05, 0.1, 0.5, and 1 Hz) to evaluate the effect of the loading frequency on the liquefaction prediction of clean sand. The results showed that the liquefaction resistance of the sand increases with the increase in the loading frequency, regardless of the initial vertical effective stress and relative density. When the loading frequency increased from 0.1 to 0.5 or 1 Hz, the maximum increase in the cyclic resistances were 15%, and 19% for loose and dense sand, respectively. For a given loading frequency, the liquefaction resistance of the sand decreased when the initial vertical effective stress increased. | Nong, Zhenzhen; Park, Sung-Sik; Jeong, Sueng-Won; Lee, Dong-Eun | Kyungpook Natl Univ, Dept Civil Engn, 80 Daehakro, Daegu 41566, South Korea; Korea Inst Geosci & Mineral Resources, Geol Environm Div, Daejeon 34132, South Korea; Kyungpook Natl Univ, Dept Architectural Engn, 80 Daehakro, Daegu 41566, South Korea | 57211377923; 36241850300; 35069425600; 56605563300 | 2017327268@knu.ac.kr;sungpark@knu.ac.kr;swjeong@kigam.re.kr;dole@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 13 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.71 | 2025-06-25 | 47 | 49 | sand liquefaction; loading frequency; cyclic direct simple shear tests | SIMPLE-SHEAR; SOILS | Cyclic direct simple shear tests; Loading frequency; Sand liquefaction | English | 2020 | 2020-07 | 10.3390/app10134502 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Effect of Formwork Removal Time Reduction on Construction Productivity Improvement by Mix Design of Early Strength Concrete | In this study, we examined the effects of cement fineness, SO3 content, an accelerating agent, and chemical admixtures mixed with unit weights of cement on concrete early strength using concrete mixtures. C24 (characteristic value of concrete, 24 MPa) was used in the experiment conducted. Ordinary Portland cement (OPC), high fineness and SO3 OPC (HFSOPC), and Early Portland cement (EPC) were selected as the study materials. The unit weights of cement were set to OPC 330, 350, and 380. Further, a concrete mixture was prepared with a triethanolamine (TEA)-based chemical admixture to HFS. A raw material analysis was conducted, and the compressive strength, temperature history, and maturity (D center dot h) were examined. Then, the vertical formwork removal time was evaluated according to the criterion of each country. Finally, the time required to develop concrete strength of 5 MPa was estimated. Results showed that the early strength of concrete mixed with HFS and EPC was greater than that exhibited by concrete with an increased unit weight of cement with OPC. In addition, when HFS was used with EPC, its strength developed early, similar to the trend exhibited by EPC, even at low temperatures. | Lee, Taegyu; Lee, Jaehyun; Kim, Jinsung; Choi, Hyeonggil; Lee, Dong-Eun | Semyung Univ, Dept Fire & Disaster Prevent, 65 Semyung Ro, Jecheon Si 27136, Chungbuk, South Korea; Seoul Natl Univ Sci & Technol, Dept Safety Engn, 232 Gongneung Ro, Seoul 01811, South Korea; Kyungpook Natl Univ, Sch Architecture Civil Environm & Energy Engn, 80 Daehakro, Daegu 41566, South Korea | Lee, Jaehyun/ABB-9148-2020 | 7501437272; 57211397021; 57219198374; 56430165800; 56605563300 | ltg777@semyung.ac.kr;archi0528@seoultech.ac.kr;kjs07406@knu.ac.kr;hgchoi@knu.ac.kr;dolee@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.54 | 2025-06-25 | 9 | 9 | early strength of concrete; cement fineness; SO3 content; accelerating agent; maturity; Ordinary Portland cement | PARTICLE-SIZE DISTRIBUTION; PORTLAND-CEMENT; EARLY-AGE; HYDRATION; ADMIXTURES; PASTES | Accelerating agent; Cement fineness; Early strength of concrete; Maturity; Ordinary Portland cement; SO<sub>3</sub> content | English | 2020 | 2020-10 | 10.3390/app10207046 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of Lactic Acid Bacteria on the Nutritive Value and In Vitro Ruminal Digestibility of Maize and Rice Straw Silage | A study was conducted to determine the effects of lactic acid bacteria (LAB) on nutritive value and in vitro rumen digestibility of maize and rice straw silages. Two identical experiments were carried out for each of the two silages. A total of five treatments were used for each experiment: (1) negative control (NC); (2) positive control (PC); (3) Lactobacillus plantarum (LPL); (4) L. paracasei (LPA); and (5) L. acidophilus (LA). Each treatment was then divided into four ensiling periods: 3, 7, 20, and 40 days with three replications. The LPL treatment had significantly higher dry matter (DM), lower ammonia-N, and a lower number of fungi on maize silage after 40 days (p < 0.05). On the other hand, the LA treatment increased DM and CP content, reduced NDF and ADF contents compared to NC, and also produced more lactic acid compared to the other LAB-treated rice straw silages. Results of the in vitro rumen fermentation of maize silages showed no significant differences in DMD after LAB inoculation. However, higher DMD and ruminal ammonia-N were shown by rice straw ensiled with L. acidophilus. In conclusion, silage additives, which could improve the ensiling process of maize and rice straw, appeared to be different and substrate specific. | Marbun, Tabita Dameria; Lee, Kihwan; Song, Jaeyong; Kwon, Chan Ho; Yoon, Duhak; Lee, Sang Moo; Kang, Jungsun; Lee, Chanho; Cho, Sangbuem; Kim, Eun Joong | Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea; Genebiotech Co Ltd, 166 Sinwonsa Ro, Gyeryong Myeon 32619, Gongju, South Korea; Circulat Agr Livestock Solut Inc, Sangju 37224, South Korea | ; Kim, Eun Joong/HGF-1639-2022; Kwon, Chan Ho/HGE-7846-2022 | 57219851669; 57219859217; 7404786651; 57201618361; 7202875754; 37059282800; 56565823900; 57188931338; 36653756600; 57213620881 | tabitamarbun@gmail.com;zoosuk87@gmail.com;jysong1976@gmail.com;chkwon@knu.ac.kr;dhyoon@knu.ac.kr;smlee0103@knu.ac.kr;jskang@genebiotech.co.kr;chlee@genebiotech.co.kr;chosb73@gmail.com;ejkim2011@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 21 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.7 | 2025-06-25 | 13 | 14 | rice straw; maize; silage; lactic acid bacteria | AEROBIC STABILITY; LACTOBACILLUS-PLANTARUM; MILK-PRODUCTION; FORAGE CROPS; FERMENTATION QUALITY; CHEMICAL-COMPOSITION; GRASS-SILAGE; FORMIC-ACID; INOCULANT; CORN | Lactic acid bacteria; Maize; Rice straw; Silage | English | 2020 | 2020-11 | 10.3390/app10217801 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Effect of Passive Support of the Spinal Muscles on the Biomechanics of a Lumbar Finite Element Model | Finite element (FE) modeling of the passive ligamentous spine is widely used to assess various biomechanical behaviors. Currently, FE models that incorporate the vertebrae, ligaments, and the personalized geometry of the bony spine may be used in conjunction with external loads from the muscles. However, while the muscles place a load (moment) on the spine and support it simultaneously, the effect of the passive support from the adjacent spinal muscles has not been considered. This study thus aims to investigate the effect of passive support from the psoas major, quadratus lumborum, and erector muscles on the range of motion (RoM) and intradiscal pressure (IDP) of the lumbar spine. Various L2-sacrum spinal models that differed only in their muscle properties were constructed and loaded with a pure moment (2.5-15.0 Nm) alone or combined with a compressive (440 or 1000 N) follower load. The RoM and IDP of the model that excluded the effect of muscles closely matched previous FE results under the corresponding load conditions. When the muscles (40-160 kPa) were included in the FE model, the RoM at L2 was reduced by up to 6.57% under a pure moment (10 Nm). The IDP was reduced by up to 6.45% under flexion and 6.84% under extension. It was also found that the erector muscles had a greater effect than the psoas major and quadratus muscles. | Kang, Inhan; Choi, Minwook; Lee, Deukhee; Noh, Gunwoo | Korea Inst Sci & Technol, Ctr Med Robot, Hwarang Ro 14 Gil, Seoul 02792, South Korea; Kyungpook Natl Univ, Sch Mech Engn, 1370 Sankyuk Dong, Daegu 41566, South Korea | 57219227460; 57217128977; 35237776600; 55010264000 | ihkang@huonsmedicare.com;mwchoi@knu.ac.kr;dkylee@kist.re.kr;gunwoo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.16 | 2025-06-25 | 4 | 5 | spine; muscle; finite element analysis; range of motion; intradiscal pressure | MECHANICAL-PROPERTIES; STRESS-ANALYSIS; MOLTEN SLAG; LIGAMENT; DISK; GRANULATION; PRESSURE; BEHAVIOR; IMPACT; INTACT | Finite element analysis; Intradiscal pressure; Muscle; Range of motion; Spine | English | 2020 | 2020-09 | 10.3390/app10186278 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Effects of Trueness and Surface Microhardness on the Fitness of Ceramic Crowns | This study aims to evaluate the fitness, surface microhardness, and trueness of crowns fabricated from three types of dental ceramic blocks (HASS Rosetta, IPS e.max CAD, and VITA Suprinity) and analyze the correlations between them. A crown was first designed in computer-aided design (CAD) software. To create a crown designed model (CDM), the design file was extracted from the CAD software, and a lithium disilicate block was processed from the file with a milling machine. To create a crown scanned model (CSM), the inside of the fabricated crown was digitized using a contact scanner. Using three-dimensional (3D) inspection software (Geomagic Control X; 3D Systems), the CDM and CSM were then superimposed, and their 3D trueness was analyzed. To measure the surface microhardness of the blocks, the specimens were polished and subjected to the Vickers hardness test. The fitness of the fabricated crowns was evaluated by applying a modified silicone replica technique. Pearson correlation analysis was performed to assess the correlations between trueness, surface microhardness, and fitness. In addition, the significance of differences between the three types of dental ceramic blocks was analyzed using one-way analysis of variance (ANOVA). Significant differences in the trueness, surface microhardness, and marginal fit were observed between ceramic blocks of different types. There were also positive correlations between trueness, surface microhardness, marginal fit, and internal fit. While the marginal fit of crowns fabricated from each of the three types of ceramic blocks was in the clinically permitted range (<120 mu m), there were differences in the trueness and surface microhardness, depending on the type of block. However, crowns fabricated from each of the three materials have surface microhardness that is clinically applicable. | Lee, Kunhee; Son, Keunbada; Lee, Kyu-bok | Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Adv Dent Device Dev Inst, Daegu 41940, South Korea | SON, Keunbada/AAG-8089-2019; Son, Keunbada/AAG-8089-2019 | 57215845014; 57202916520; 15925571200 | kunhee00@naver.com;sonkeunbada@gmail.com;kblee@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.23 | 2025-06-25 | 7 | 7 | trueness; marginal and internal fit; surface microhardness; ceramic; dentistry | FIT | Ceramic; Dentistry; Marginal and internal fit; Surface microhardness; Trueness | English | 2020 | 2020-03 | 10.3390/app10051858 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enriching Knowledge Base by Parse Tree Pattern and Semantic Filter | This paper proposes a simple knowledge base enrichment based on parse tree patterns with a semantic filter. Parse tree patterns are superior to lexical patterns used commonly in many previous studies in that they can manage long distance dependencies among words. In addition, the proposed semantic filter, which is a combination of WordNet-based similarity and word embedding similarity, removes parse tree patterns that are semantically irrelevant to the meaning of a target relation. According to our experiments using the DBpedia ontology and Wikipedia corpus, the average accuracy of the top 100 parse tree patterns for ten relations is 68%, which is 16% higher than that of lexical patterns, and the average accuracy of the newly extracted triples is 60.1%. These results prove that the proposed method produces more relevant patterns for the relations of seed knowledge, and thus more accurate triples are generated by the patterns. | Yoon, Hee-Geun; Park, Seyoung; Park, Seong-Bae | Kyungpook Natl Univ, Sch Comp Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea; Kyung Hee Univ, Dept Comp Sci & Engn, 1732 Deogyeong Daero, Yongin 17104, Gyeonggi Do, South Korea | Yoon, Hee-Geun/ABG-2942-2021 | 24722061700; 14045781800; 7501838676 | hgyoon@knu.ac.kr;seyoung@knu.ac.kr;sbpark71@khu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0 | 2025-06-25 | 0 | 0 | knowledge enriching; parse tree pattern; semantic filter; word embedding; semantic relevance | SIMILARITY | Knowledge enriching; Parse tree pattern; Semantic filter; Semantic relevance; Word embedding | English | 2020 | 2020-09 | 10.3390/app10186209 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Estimating the Rank of a Nonnegative Matrix Factorization Model for Automatic Music Transcription Based on Stein's Unbiased Risk Estimator | In this paper, methods to estimate the number of basis vectors of the nonnegative matrix factorization (NMF) of automatic music transcription (AMT) systems are proposed. Previously, studies on NMF-based AMT have demonstrated that the number of basis vectors affects the performance and that the number of note events can be a good selection as the rank of NMF. However, many NMF-based AMT methods do not provide a method to estimate the appropriate number of basis vectors; instead, the number is assumed to be given in advance, even though the number of basis vectors significantly affects the algorithm's performance. Recently, based on Bayesian methods, certain estimation algorithms for the number of basis vectors have been proposed; however, they are not designed to be used as music transcription algorithms but are components of specific NMF methods and thus cannot be used generally as NMF-based transcription algorithms. Our proposed estimation algorithms are based on eigenvalue decomposition and Stein's unbiased risk estimator (SURE). Because the SURE method requires variance in undesired components as a priori knowledge, the proposed algorithms estimate the value using random matrix theory and first and second onset information in the input music signal. Experiments were then conducted for the AMT task using the MIDI-aligned piano sounds (MAPS) database, and these algorithms were compared with variational NMF, gamma process NMF, and NMF with automatic relevance determination algorithms. Based on experimental results, the conventional NMF-based transcription algorithm with the proposed rank estimation algorithms demonstrated enhanced F1 score performances of 2-3% compared to the algorithms. While the performance advantages are not significantly large, the results are meaningful because the proposed algorithms are lightweight, are easy to combine with any other NMF methods that require an a priori rank parameter, and do not have setting parameters that considerably affect the performance. | Lee, Seokjin | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea | 36174416200 | sjlee6@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 8 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.23 | 2025-06-25 | 7 | 8 | automatic music transcription; nonnegative matrix factorization; number of basis vectors; Stein's unbiased risk estimator | SIGNAL; PITCH; SURE | Automatic music transcription; Nonnegative matrix factorization; Number of basis vectors; Stein's unbiased risk estimator | English | 2020 | 2020-02 | 10.3390/app10082911 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Evaluation of In-Package Atmospheric Dielectric Barrier Discharge Cold Plasma Treatment as an Intervention Technology for Decontaminating Bulk Ready-To-Eat Chicken Breast Cubes in Plastic Containers | Featured Application In-package atmospheric cold plasma treatment shows potential as an intervention technology increasing microbiological safety and shelf-life of packaged ready-to-eat chicken products, leading to toxicological safety overall. This article evaluates the effects of in-package atmospheric dielectric barrier discharge cold plasma (ADCP) treatment on microbial inactivation, nitrate and nitrite contents, oral toxicity, and storage quality of protein-coated boiled chicken breast cubes (CBCs). ADCP treatment at 24 kV for 3 min inactivated natural mesophilic aerobic bacteria,Salmonella, and Tulane virus in CBCs by 0.7 +/- 0.2, 1.4 +/- 0.1 log CFU/cube, and 1.1 +/- 0.2 log PFU/cube, respectively. ADCP treatment did not affect the nitrite content of CBCs (p> 0.05). Furthermore, the hematological and blood biochemical parameters from toxicity tests indicated the toxicological safety of ADCP-treated CBCs. Microbial counts of natural bacteria andSalmonellain ADCP-treated CBCs were lower than the ADCP-untreated CBCs by 0.7-0.9 and 1.4-1.7 log CFU/cube, respectively, throughout post-treatment storage at 4 degrees C for 21 d. ADCP treatment did not alter the pH, color, total volatile basic nitrogen, lipid oxidation, and tenderness of CBCs during storage at 4 and 24 degrees C, and did not change the sensory properties of CBCs following a 3 d storage period at 4 degrees C (p> 0.05). Thus, ADCP treatment has the potential to be applied as a method to increase the microbiological safety of packaged ready-to-eat chicken products, leading to overall toxicological safety. | Lee, Eun Song; Cheigh, Chan-Ick; Kang, Joo Hyun; Lee, Seung Young; Min, Sea C. | Seoul Womens Univ, Dept Food Sci & Technol, Seoul 01797, South Korea; Kyungpook Natl Univ, Dept Food & Food Serv Ind, Sangju 37131, South Korea | 57201332804; 6506587023; 57216291635; 57205333419; 7202852772 | pineles@naver.com;cic@knu.ac.kr;as03226@naver.com;seung_30@naver.com;smin@swu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 1.95 | 2025-06-25 | 33 | 39 | cold plasma; microbial inactivation; oral toxicity; storage quality; chicken breast | PRESSURE PLASMA; ESCHERICHIA-COLI; LISTERIA-MONOCYTOGENES; LIPID OXIDATION; TULANE VIRUS; EDIBLE FILMS; INACTIVATION; SALMONELLA; QUALITY; MEAT | Chicken breast; Cold plasma; Microbial inactivation; Oral toxicity; Storage quality | English | 2020 | 2020-09 | 10.3390/app10186301 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Green Pepper (Piper nigrum L.) Extract Suppresses Oxidative Stress and LPS-Induced Inflammation via Regulation of JNK Signaling Pathways | In this study, we compared the physicochemical properties and the antioxidant capacities of black and green pepper. Green pepper from India (GPI) and Sri Lanka (GPS) had higher Hunter L* and b* values and lower a* values than black pepper from India (BPI) and Sri Lanka (BPS). The contents of chlorophyll a and b, flavonoids, and phenolic compounds in GPI and GPS were higher than those in BPI and BPS. The peppercorns showed the following decreasing order of 2,2-diphenyl-1-picrylhydrazyl and 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid radical scavenging capacities: GPI > GPS > BPI > BPS. High-performance liquid chromatography showed that the highest piperine content was present in GPI (8613.27 +/- 45.86 mg/100 g). We further investigated the anti-inflammatory capacity of the green pepper. GPS and GPI significantly suppressed lipopolysaccharide (LPS)-induced nitrite production and inducible nitric oxide synthase expression without being cytotoxic to RAW 264.7 cells. GPS and GPI also suppressed the LPS-induced phosphorylation of mitogen-activated protein kinases, but not p65. GPS had a higher inhibitory effect on LPS-induced c-Jun phosphorylation and translocation from the cytosol to the nucleus than GPI. Thus, the findings of our study suggest that green pepper has the potential to be an effective nutraceutical against oxidative and inflammatory stress. | Kim, Dae Won; Kim, Min Jeong; Shin, Youngjae; Jung, Sung Keun; Kim, Young-Jun | Seoul Natl Univ Sci & Technol, Dept Food Sci & Technol, Seoul 01811, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Dankook Univ, Dept Food Engn, Cheonan 31116, Chungnam, South Korea | Kim, Joo/X-7562-2019; Jung, SUNG KEUN/AGR-2623-2022 | 57216224891; 57215818497; 17342820900; 35310491400; 57211016047 | kdw3566@seoultech.ac.kr;excellent8@knu.ac.kr;ys234@dankook.ac.kr;skjung04@knu.ac.kr;kimyj@seoultech.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.62 | 2025-06-25 | 12 | 12 | green pepper; antioxidant; anti-inflammation; nutraceutical; piperine; mitogen-activated protein kinases (MAPKs) | NF-KAPPA-B; ANTIOXIDANT ACTIVITY; NITRIC-OXIDE; CELLS; INHIBITION; EXPRESSION; DISEASES; AP-1; OIL | Anti-inflammation; Antioxidant; Green pepper; Mitogen-activated protein kinases (MAPKs); Nutraceutical; Piperine | English | 2020 | 2020-04 | 10.3390/app10072519 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Improved U-Net: Fully Convolutional Network Model for Skin-Lesion Segmentation | The early and accurate diagnosis of skin cancer is crucial for providing patients with advanced treatment by focusing medical personnel on specific parts of the skin. Networks based on encoder-decoder architectures have been effectively implemented for numerous computer-vision applications. U-Net, one of CNN architectures based on the encoder-decoder network, has achieved successful performance for skin-lesion segmentation. However, this network has several drawbacks caused by its upsampling method and activation function. In this paper, a fully convolutional network and its architecture are proposed with a modified U-Net, in which a bilinear interpolation method is used for upsampling with a block of convolution layers followed by parametric rectified linear-unit non-linearity. To avoid overfitting, a dropout is applied after each convolution block. The results demonstrate that our recommended technique achieves state-of-the-art performance for skin-lesion segmentation with 94% pixel accuracy and a 88% dice coefficient, respectively. | Sanjar, Karshiev; Bekhzod, Olimov; Kim, Jaeil; Kim, Jaesoo; Paul, Anand; Kim, Jeonghong | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea | ; Olimov, Bekhzod/AAA-9362-2021; Kim, Jaesoo/GYQ-9324-2022; Paul, Anand/V-6724-2017 | 57210910507; 57220579660; 57211615348; 57191684854; 56650522400; 55138548100 | sanikarshiev@gmail.com;bekhzod.olimov@gmail.com;jaeilkim@knu.ac.kr;kjs@knu.ac.kr;anad@knu.ac.kr;jhk@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 10 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.86 | 2025-06-25 | 25 | 29 | skin-lesion segmentation; interpolation; PReLU | Interpolation; PReLU; Skin-lesion segmentation | English | 2020 | 2020-05 | 10.3390/app10103658 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Improving Singing Voice Separation Using Curriculum Learning on Recurrent Neural Networks | Featured Application Speech enhancement; speech recognition; music information retrieval. Abstract Single-channel singing voice separation has been considered a difficult task, as it requires predicting two different audio sources independently from mixed vocal and instrument sounds recorded by a single microphone. We propose a new singing voice separation approach based on the curriculum learning framework, in which learning is started with only easy examples and then task difficulty is gradually increased. In this study, we regard the data providing obviously dominant characteristics of a single source as an easy case and the other data as a difficult case. To quantify the dominance property between two sources, we define a dominance factor that determines a difficulty level according to relative intensity between vocal sound and instrument sound. If a given data is determined to provide obviously dominant characteristics of a single source according to the factor, it is regarded as an easy case; otherwise, it belongs to a difficult case. Early stages in the learning focus on easy cases, thus allowing rapidly learning overall characteristics of each source. On the other hand, later stages handle difficult cases, allowing more careful and sophisticated learning. In experiments conducted on three song datasets, the proposed approach demonstrated superior performance compared to the conventional approaches. | Kang, Seungtae; Park, Jeong-Sik; Jang, Gil-Jin | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Hankuk Univ Foreign Studies, Dept English Linguist & Language Technol, Seoul 02450, South Korea | 57205443421; 55119502600; 7102646102 | cdef3456@naver.com;parkjs@hufs.ac.kr;gjang@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 7 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.23 | 2025-06-25 | 3 | 4 | audio source separation; singing voice separation; weighted loss function; curriculum learning; recurrent neural network; U-Net | NONNEGATIVE MATRIX FACTORIZATION | Audio source separation; Curriculum learning; Recurrent neural network; Singing voice separation; U-Net; Weighted loss function | English | 2020 | 2020-04 | 10.3390/app10072465 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Inference of Drawing Elements and Space Usage on Architectural Drawings Using Semantic Segmentation | Artificial intelligence presents an optimized alternative by performing problem-solving knowledge and problem-solving processes under specific conditions. This makes it possible to creatively examine various design alternatives under conditions that satisfy the functional requirements of the building. In this study, in order to develop architectural design automation technology using artificial intelligence, the characteristics of an architectural drawings, that is, the architectural elements and the composition of spaces expressed in the drawings, were learned, recognized, and inferred through deep learning. The biggest problem in applying deep learning in the field of architectural design is that the amount of publicly disclosed data is absolutely insufficient and that the publicly disclosed data also haves a wide variety of forms. Using the technology proposed in this study, it is possible to quickly and easily create labeling images of drawings, so it is expected that a large amount of data sets that can be used for deep learning for the automatic recommendation of architectural design or automatic 3D modeling can be obtained. This will be the basis for architectural design technology using artificial intelligence in the future, as it can propose an architectural plan that meets specific circumstances or requirements. | Seo, Jihyo; Park, Hyejin; Choo, Seungyeon | Kyungpook Natl Univ, Sch Architecture, 80 Daehak Ro, Daegu 41566, South Korea | Choo, Seungyeon/JFB-0390-2023 | 57210795460; 57226002455; 36835366900 | jihyoseo@knu.ac.kr;phj8598@knu.ac.kr;choo@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 20 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.54 | 2025-06-25 | 13 | 18 | image segmentation; labeling; DeeplabV3+; deep learning; architectural design | Architectural design; Deep learning; DeeplabV3+; Image segmentation; Labeling | English | 2020 | 2020-10 | 10.3390/app10207347 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Intersection Routing Based on Fuzzy Multi-Factor Decision for VANETs | Vehicular ad hoc network (VANET) is a special form of mobile ad hoc network (MANET), which plays a key role in the intelligent transportation system (ITS). Though many outstanding geographic routing protocols are designed for VANETs, a majority of them use parameters that only affect routing performance. In this article, we propose an intersection routing based on fuzzy multi-factor decision (IRFMFD), which utilizes several features. The scheme is divided into two parts, namely vehicular decision management and intersection decision management. In the vehicular component, candidate vehicles between two static nodes (SNs) located at two intersections derive potential routing paths considering distance, neighbor quantity, and relative velocity. In the intersection component, the candidate SN was chosen from the current intersection's 2-hop neighbors which were connected with the current intersection by a route that was decided on in part one. To get the best scheme, we also introduced other factors to estimate the number of hops in each link and link lifetime. The simulation shows that the IRFMFD outperforms on delivery ratio and end-to-end delay compared with AODV (Ad hoc on-demand distance vector), GPSR (Greedy perimeter stateless routing) and GeOpps (Geographical opportunistic routing). | Cao, Zhenbo; Silva, Bhagya Nathali; Diyan, Muhammad; Li, Jilong; Han, Kijun | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Univ Sri Jayawardenepura, Dept Comp Engn, Fac Engn, Nugegoda 10250, Sri Lanka; Jiangsu Univ Technol, Sch Comp Engn, Changzhou 213001, Jiangsu, Peoples R China | Silva, Bhagya/AAW-1014-2021; Diyan, Muhammad/AAM-5848-2021; Cao, Zhenbo/AAA-3489-2022 | 57145726600; 57192304387; 26028317800; 55859277700; 7402963670 | czb0909@knu.ac.kr;nathalis@netopia.knu.ac.kr;m.diyan@knu.ac.kr;jeelong@jsut.edu.cn;kjhan@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 18 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.39 | 2025-06-25 | 7 | 6 | VANET; MANET; ITS; fuzzy number; routing protocol | Fuzzy number; ITS; MANET; Routing protocol; VANET | English | 2020 | 2020-09 | 10.3390/app10186613 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Large-Scale Data Computing Performance Comparisons on SYCL Heterogeneous Parallel Processing Layer Implementations | Today, many big data applications require massively parallel tasks to compute complicated mathematical operations. To perform parallel tasks, platforms like CUDA (Compute Unified Device Architecture) and OpenCL (Open Computing Language) are widely used and developed to enhance the throughput of massively parallel tasks. There is also a need for high-level abstractions and platform-independence over those massively parallel computing platforms. Recently, Khronos group announced SYCL (C++ Single-source Heterogeneous Programming for OpenCL), a new cross-platform abstraction layer, to provide an efficient way for single-source heterogeneous computing, with C++-template-level abstractions. However, since there has been no official implementation of SYCL, we currently have several different implementations from various vendors. In this paper, we analyse the characteristics of those SYCL implementations. We also show performance measures of those SYCL implementations, especially for well-known massively parallel tasks. We show that each implementation has its own strength in computing different types of mathematical operations, along with different sizes of data. Our analysis is available for fundamental measurements of the abstract-level cost-effective use of massively parallel computations, especially for big-data applications. | Shin, Woosuk; Yoo, Kwan-Hee; Baek, Nakhoon | Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Chungbuk Natl Univ, Dept Comp Sci, Cheongju 28644, South Korea | 57192417891; 8859846800; 7007017954 | w.shin@knu.ac.kr;khyoo@cbnu.ac.kr;nbaek@knu.ac.kr; | APPLIED SCIENCES-BASEL | APPL SCI-BASEL | 2076-3417 | 10 | 5 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;ENGINEERING, MULTIDISCIPLINARY;MATERIALS SCIENCE, MULTIDISCIPLINARY;PHYSICS, APPLIED | 2020 | 2.679 | 41.7 | 0.78 | 2025-06-25 | 9 | 14 | single-source DSL (Domain Specific Language); heterogeneous computing; parallel computing; GPGPU (General Purpose Graphics Processing Unit) | GPGPU (General purpose graphics processing unit); Heterogeneous computing; Parallel computing; Single-source DSL (Domain specific language) | English | 2020 | 2020-03 | 10.3390/app10051656 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
