| ○ | Proceedings Paper | Analysis Description Languages for the LHC | An analysis description language is a domain specific language capable of describing the contents of an LHC analysis in a standard and unambiguous way, independent of any computing framework. It is designed for use by anyone with an interest in, and knowledge of, LHC physics, i.e., experimentalists, phenomenologists and other enthusiasts. Adopting analysis description languages would bring numerous benefits for the LHC experimental and phenomenological communities ranging from analysis preservation beyond the lifetimes of experiments or analysis software to facilitating the abstraction, design, visualization, validation, combination, reproduction, interpretation and overall communication of the analysis contents. Here, we introduce the analysis description language concept and summarize the current efforts ongoing to develop such languages and tools to use them in LHC analyses. | Sekmen, Sezen; Gras, Philippe; Gray, Lindsey; Krikler, Benjamin; Pivarski, Jim; Prosper, Harrison B.; Rizzi, Andrea; Unel, Gokhan; Watts, Gordon | Kyungpook Natl Univ, Ctr High Energy Phys, Daegu, South Korea; Univ Paris Saclay, CEA, Inst Rech Lois Fondament Univers, Gif Sur Yvette, France; Fermilab Natl Accelerator Lab, Batavia, IL 60510 USA; Univ Bristol, HH Wills Phys Lab, Bristol, Avon, England; Princeton Univ, Dept Phys, Princeton, NJ USA; Florida State Univ, Dept Phys, Tallahassee, FL USA; INFN, Pisa, Italy; Univ Pisa, Pisa, Italy; Univ Calif Irvine, Dept Phys & Astron, Irvine, CA USA; Univ Washington, Dept Phys, Seattle, WA USA | unel, gokhan/KFB-1065-2024 | ssekmen@cern.ch; | EIGHTH ANNUAL CONFERENCE ON LARGE HADRON COLLIDER PHYSICS, LHCP2020 | 0 | English | 2021 | 2021 | 바로가기 | ||||||||||||||||||||||||
| ○ | Book chapter | Analysis of cell and nucleus genome by next-generation sequencing | Genomic variants that are acquired during a lifetime as a result of development, environmental exposure, and aging are present in every cell of the human body. While some variants are shared between cells, most of them are not. Therefore, analyzing the nuclear genome of a cell is the ultimate way to study genomic mosaicism. However, comprehensive evaluation of variations in a single cell's genome is not yet possible due to unresolved technical issues, while the analysis of a bulk of cells can provide a valuable insight into mosaicism in a studied sample. Here, we describe, compare, and discuss strategies, experimental techniques, and analytical methods for discovery of a spectrum of mosaic variants from a bulk of cells and from single cells. We specifically focus on next-generation sequencing technologies for genome analysis as they enable the discovery of mosaic variants of all types. © Springer Nature Switzerland AG 2020. | Oh, Ji Won; Abyzov, Alexej | Department of Anatomy, School of Medicine, Kyungpook National University, Daegu, South Korea, Biomedical Research Institute, Kyungpook National University Hospital, Daegu, South Korea; Department of Health Sciences Research, Center for Individualized Medicine, Mayo Clinic, Rochester, MN, United States | 36093206200; 8732206000 | abyzov.alexej@mayo.edu; | Human Interphase Chromosomes: Biomedical Aspects | 0.93 | 2025-07-30 | 1 | Copy number variation (CNV); Genome variation; Insertion or deletion (Indel); Lineage tracing; Mobile element insertion (MEI); Mosaic mutation; Mosaic variant; Mosaicism; Next-generation sequencing; Single nucleotide variation (SNV); Single-cell genome; Somatic variant; Structural variation (SV); Whole-genome amplification (WGA) | English | Final | 2021 | 10.1007/978-3-030-62532-0_3 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | Analysis of CO and NOx deviations under on-road driving test of gasoline vehicle with three-way catalyst | RDE has recently been adopted in emission tests in order to measure exhaust gases under actual driving conditions. However, difference in driving routes and traffic conditions would cause deviations in the emission results. A correction factor is applied to compensate for the deviations, but it does not work properly. Thus, CO and NOx deviations were analyzed in the present study. Ten cases of on-road driving were conducted on three driving routes. CO emissions were highly dependent on the coolant temperature and equivalence ratio. About 10 % of CO was exhausted during the cold start, and the rich air-fuel mixture increased the CO emissions by more than two times. NOx emission was also strongly affected by the equivalence ratio and catalyst temperature. About 15 % of NOx was exhausted when the catalyst temperature was low. Oxygen saturation of the catalyst and high load condition were also the reasons for the NOx deviation.

| ○ | ○ | Article | Analysis of Co-registration Performance According to Geometric Processing Level of KOMPSAT-3/3A Reference Image | This study analyzed co-registration results according to the geometric processing level of reference image, which are Level 1R and Level 1G provided from KOMPSAT-3 and KOMPSAT-3A images. We performed co-registration using each Level 1R and Level 1G image as a reference image, and Level 1R image as a sensed image. For constructing the experimental dataset, seven Level 1R and 1G images of KOMPSAT-3 and KOMPSAT-3A acquired from Daejeon, South Korea, were used. To coarsely align the geometric position of the two images, SURF (Speeded-Up Robust Feature) and PC (Phase Correlation) methods were combined and then repeatedly applied to the overlapping region of the images. Then, we extracted tie-points using the SURF method from coarsely aligned images and performed fine co-registration through affine transformation and piecewise Linear transformation, respectively, constructed with the tie-points. As a result of the experiment, when Level 1G image was used as a reference image, a relatively large number of tie-points were extracted than Level 1R image. Also, in the case where the reference image is Level 1G image, the root mean square error of co-registration was 5 pixels less than the case of Level 1R image on average. We have shown from the experimental results that the co-registration performance can be affected by the geometric processing level related to the initial geometric relationship between the two images. Moreover, we confirmed that the better geometric quality of the reference image achieved the more stable co-registration performance. | Yun, Yerin; Kim, Taeheon; Oh, Jaehong; Han, Youkyung | Kyungpook Natl Univ, Dept Geospatial Informat, Daegu, South Korea; Kyungpook Natl Univ, Sch Convergence & Fus Syst Engn, Daegu, South Korea; Korea Maritime & Ocean Univ, Dept Civil Engn, Busan, South Korea; Seoul Natl Univ Sci & Technol, Dept Civil Engn, Seoul, South Korea | Kim, Taeheon/LQJ-6143-2024 | 57218228861; 57204217686; 36140723100; 55457676600 | han602@seoultech.ac.kr; | KOREAN JOURNAL OF REMOTE SENSING | KOREAN J REMOTE SENS | 1225-6161 | 2287-9307 | 37 | 2 | ESCI | REMOTE SENSING | 2021 | N/A | 0.67 | 2025-07-30 | 2 | 8 | KOMPSAT-3.3A; Co-registration; Geometric processing level; Speeded-Up Robust Feature (SURF); Phase Correlation (PC) | Co-registration; Geometric processing level; KOMPSAT-3·3A; Phase Correlation (PC); Speeded-Up Robust Feature (SURF) | Korean | 2021 | 2021-04 | 10.7780/kjrs.2021.37.2.4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Analysis of Factors Affecting the Posted Price and Actual Transaction Price of Apartment in Daegu Metropolitan City Using Multiple Regression Analysis | In Korea, real estate prices have risen to their highest level in the past five years. Income levels are not supported, apartment consumers tend to rush to buy apartments through excessive loans. It is necessary to find factors that affect apartment prices for reasonable purchases by consumers. However, previous studies have limited interest in some variable effects or limited analysis of specific regions. In this paper, we investigated all the apartments in legal district(dong), Daegu Metropolitan City. and we tried to find factors that affect the Posted price and actual transaction price of apartments through multiple regression analysis. As a result, we found six factors that affect apartment prices. Specifically, physical factors such as the dedicated area, elapsed years, and the number of highest floors could be found. In addition, the number of private academies, the number of households, and the park area were derived. it was different from the expectation that apartment prices would decrease as the park area per person increased. © 2021 Architectural Institute of Korea. | Kim, Seon-Hyeon; Kim, Tae-Hoon; Choo, Seung-Yeon | School of Architecture, Kyungpook National University, South Korea; School of Architecture, Kyungpook National University, South Korea; School of Architecture, Kyungpook National University, South Korea | 57547407700; 58260945000; 36835366900 | choo@knu.ac.kr; | Journal of the Architectural Institute of Korea | 2733-6239 | 37 | 11 | 0 | 2025-07-30 | 0 | Apartment Actual Transaction Price; Apartment Posted Price; Building Register; Mutiple Regression Analysis; Public Data | Korean | Final | 2021 | 10.5659/jaik.2021.37.11.131 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Analysis of ink for the woodblock printing of Samguk Yusa (I) - Ink with low solid content | In this study, the characteristics of ink for the woodblock printing of Samguk Yusa, provided by the Korean Studies Institute, were analyzed. Owing to the influence of the glue that was added to manufacture the ink, its contact angle was maintained for a longer period than that of distilled water even after it was dropped on Hanji, a Korean traditional paper. Regarding the roundness of the ink, it exhibited a smaller diameter spread than that of distilled water after the same amounts of both substances were dropped on Hanji for 1 min; this result was also attributed to the effect of the glue. Based on the field emission scanning electron microscopy (FE-SEM) measurement and particle-size analysis of carbon black in the ink, its average diameter was 59 nm; its particle size was lower than that of general pine soot ink. Therefore, if a higher concentration of ink than those of the presently available ones is used, such an ink can be used for the woodblock printing of Samguk Yusa. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | Article | Analysis of Ink for Woodblock Printing of Samguk Yusa (II) - Ink with High Solid Content; [삼국유사 목판본 인출용 먹의 특성 분석 (II)- 높은 고형분 함량의 먹물 -] | This study analyzes the physical and chemical properties of ink with high solid content for the woodblock printing of Samguk Yusa. Compared with pine or oil soot inks, the organic ingredients in ink for the woodblock printing of Samguk Yusa had a higher nitrogen concentration and the inorganic elements had a lower ash level. In addition, in the IR analysis, C=C bonds of 1650–1620 cm-1 intensity were confirmed in the ink for the woodblock printing of Samguk Yusa, and the average particle diameter of these inks was confirmed to be about 61 nm. Because of the glue used in the ink’s production, the ink had a higher cohesive force and was less smeared on the Hanji. When dried in UV irradiation, it appears that the color of the printed part on Hanji will become more distinct. © 2021 Korean Technical Assoc. of the Pulp and Paper Industry.

| ○ | ○ | Article | Analysis of international traveler mobility patterns in Tokyo to identify geographic foci of dengue fever risk | Travelers play a role in triggering epidemics of imported dengue fever because they can carry the virus to other countries during the incubation period. If a traveler carrying dengue virus visits open green space and is bitten by mosquitoes, a local outbreak can ensue. In the present study, we aimed to understand the movement patterns of international travelers in Tokyo using mobile phone data, with the goal of identifying geographical foci of dengue transmission. We analyzed datasets based on mobile phone access to WiFi systems and measured the spatial distribution of international visitors in Tokyo on two specific dates (one weekday in July 2017 and another weekday in August 2017). Mobile phone users were classified by nationality into three groups according to risk of dengue transmission. Sixteen national parks were selected based on their involvement in a 2014 dengue outbreak and abundance of Aedes mosquitoes. We found that not all national parks were visited by international travelers and that visits to cemeteries were very infrequent. We also found that travelers from countries with high dengue prevalence were less likely to visit national parks compared with travelers from dengue-free countries. Travelers from countries with sporadic dengue cases and countries with regional transmission tended to visit common destinations. By contrast, the travel footprints of visitors from countries with continuous dengue transmission were focused on non-green spaces. Entomological surveillance in Tokyo has been restricted to national parks since the 2014 dengue outbreak. However, our results indicate that areas subject to surveillance should include both public and private green spaces near tourist sites. | Yuan, Baoyin; Lee, Hyojung; Nishiura, Hiroshi | Hokkaido Univ, Grad Sch Med, Kita Ku, Kita 15 Jo Nishi 7 Chome, Sapporo, Hokkaido 0608638, Japan; Japan Sci & Technol Agcy, CREST, Honcho 4-1-8, Kawaguchi, Saitama 3320012, Japan; South China Univ Technol, Sch Math, 381 Wushan Rd, Guangzhou, Peoples R China; Kyungpook Natl Univ, Dept Stat, Daegu 41566, South Korea; Kyoto Univ, Sch Publ Hlth, Sakyo Ku, Yoshidakonoecho, Kyoto 6068501, Japan | Nishiura, Hiroshi/JPX-7690-2023; Yuan, Baoyin/GNM-5458-2022 | 56316616700; 57196021198; 7005501836 | nishiura.hiroshi.5r@kyoto-u.ac.jp; | THEORETICAL BIOLOGY AND MEDICAL MODELLING | 1742-4682 | 18 | 1 | 0.32 | 2025-07-30 | 4 | 5 | Dengue; Imported case; Transmission; Tourism; Sightseeing; Coherence | INTERRATER RELIABILITY; DISEASE; EPIDEMICS; IMPACT; JAPAN | Coherence; Dengue; Imported case; Sightseeing; Tourism; Transmission | Animals; Dengue; Disease Outbreaks; Prevalence; Tokyo; Travel; animal; dengue; epidemic; Japan; prevalence; travel | English | 2021 | 2021-10-03 | 10.1186/s12976-021-00149-8 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | Article | Analysis of Optimal Pathways for Terrestrial LiDAR Scanning for the Establishment of Digital Inventory of Forest Resources | This study was conducted to identify the applicability of a LiDAR sensor to forest resources inventories by comparing data on a tree's position, height, and DBH obtained by the sensor with those by existing forest inventory methods, for the tree species of Criptomeria japonica in Jeolmul forest in Jeju, South Korea. To this end, a backpack personal LiDAR (Greenvalley International, Model D50) was employed. To facilitate the process of the data collection, patterns of collecting the data by the sensor were divided into seven ones, considering the density of sample plots and the work efficiency. Then, the accuracy of estimating the variables of each tree was assessed. The amount of time spent on acquiring and processing the data by each method was compared to evaluate the efficiency. The findings showed that the rate of detecting standing trees by the LiDAR was 100%. Also, the high statistical accuracy was observed in both Pattern 5 (DBH: RMSE 1.07 cm, Bias -0.79 cm, Height: RMSE 0.95 m, Bias -3.2 m), and Pattern 7 (DBH: RMSE 1.18 cm, Bias -0.82 cm, Height: RMSE 1.13 m, Bias -2.62 m), compared to the results drawn in the typical inventory manner. Concerning the time issue, 115 to 135 minutes per 1ha were taken to process the data by utilizing the LiDAR, while 375 to 1,115 spent in the existing way, proving the higher efficiency of the device. It can thus be concluded that using a backpack personal LiDAR helps increase efficiency in conducting a forest resources inventory in an planted coniferous forest with understory vegetation, implying a need for further research in a variety of forests. | Ko, Chi-Ung; Yim, Jong-Su; Kim, Dong-Geun; Kang, Jin-Taek | Natl Inst Forest Sci, Div Forest Ind, Seoul, South Korea; Kyungpook Univ, Dept Ecol & Environm Syst, Grad Sch, Daegu, South Korea | ko, chiung/AAP-8460-2021 | beg8bune@korea.kr; | KOREAN JOURNAL OF REMOTE SENSING | KOREAN J REMOTE SENS | 1225-6161 | 2287-9307 | 37 | 2 | ESCI | REMOTE SENSING | 2021 | N/A | 1 | LiDAR; Backpack laser scanning; Terrestrial laser scanning; Forest inventory; point cloud | LASER; HEIGHT | Korean | 2021 | 2021-04 | 10.7780/kjrs.2021.37.2.6 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Article | Analysis of PC20-FEF25%-75% and ΔFVC in the methacholine bronchial provocation test | Purpose: Forced expiratory flow between 25% and 75% (FEF25%-75%) is known to sensitively reflect bronchial obstruction. Methacholine challenge test (MCT) has shown varying reduction levels of forced vital capacity (FVC) with the reduction in forced expiratory volume in 1 second (FEV1) in asthma. The aim of this study was to evaluate the clinical implication of provocative concentration causing a 20% fall in FEF25%-75% (PC20-FEF25%-75%) and the percentage fall in FVC at the PC20 dose of methacholine (Delta FVC). Methods: A total of 194 children who visited the hospital due to respiratory symptoms and underwent MCT were analyzed retrospectively. The patients were divided into 3 groups. Group I had both PC20-FEV1 and PC20-FEF25%-75% above 16 mg/mL; group II had a PC20-FEF25%-75% that fell below 16 mg/mL but PC20-FEV1 was 16 mg/mL or above; group III had a PC20-FEV1 and a PC20-FEF25%-75% that both fell below 16 mg/mL. Results: In group II, PC20-FEV1 was lower (P= 0.026) and the rate of change in FEV1 and FEF25%-75% from baseline to 16 mg/mL of methacholine concentration was greater than in group I (both P< 0.001). Levels of PC20-FEF25%-75% were higher in group II compared to group III (P< 0.001). Delta FVC showed a correlation with PC20-FEV1 (P< 0.001) only in the whole group. Conclusion: In asthmatic children, PC20-FEF25%-75% may be associated with bronchial hyperresponsiveness. Delta FVC was not associated with other parameters in either group. For subjects with a positive finding of PC20-FEF25%-75% and a negative finding of MCT, the progression to asthma can be suspected. | Kim, Hyeon A.; Kwon, Jung Eun; Ahn, Ji Young; Choe, Jae Young; Kim, Dong Sub; Park, Sook Hyun; Hyun, Myung Chul; Choi, Bong Seok | Kyungpook Natl Univ, Sch Med, Dept Pediat, 680 Gukchaebosang Ro, Daegu 41944, South Korea; Yeungnam Univ, Dept Pediat, Coll Med, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Emergency Med, Daegu, South Korea | ahn, jiyoung/KSM-2201-2024; Kim, Dong/G-7392-2017 | bschoi@knu.ac.kr; | ALLERGY ASTHMA & RESPIRATORY DISEASE | ALLERGY ASTHMA RESPI | 2288-0402 | 2288-0410 | 9 | 3 | ESCI | ALLERGY | 2021 | N/A | 1 | Methacholine challenge test; Asthma; Child; Vital capacity; Forced expiratory flow | FORCED EXPIRATORY FLOW; CHALLENGE TESTS; VITAL CAPACITY; ASTHMA; HYPERRESPONSIVENESS; IMPAIRMENT; PREDICTOR; MARKER; FALL; PC20 | Korean | 2021 | 2021-07 | 10.4168/aard.2021.9.3.141 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Analysis of power requirement of a small-sized tracked-tractor during agricultural field operations | A low-powered and high-efficiency electric tracked-tractor would be a suitable option for aged and female farmers to accomplish agricultural field operations such as grass mowing, land leveling, and chemical spraying. The purpose of the study was to analyze the power requirement of a small-sized tracked-tractor during agricultural field operations. A lawnmower and a rear sprayer-trailer were attached to the tractor base, and the average power requirement was measured. The forward speed was considered during the field experiment up to 6 km/h for four different operating stages. The torque data were obtained for unloaded and loaded conditions through a wireless data logger, and a GPS receiver was used to measure the working speed of the tractor. A data acquisition module was used to acquire the sensor signals. The average power requirements for the empty platform with the driver, a lawnmower, a sprayer-trailer (150-L payload), and a lawnmower and 150-L payload trailer were 0.93, 1.27, 1.45, and 1.70 kW, respectively. The result showed the lowest power was required for operating only the tractor, and it was about 51.15% of the motor rated power, where the maximum power consumed approximately 85% of the total rated power to operate both of the lawnmower and sprayer-trailer. The average power requirements of the tracked tractor varied due to the different payloads and operating stages. The experimental results presented in this study would provide guidelines to improve and commercialize the prototype of the small-scaled tracked-tractor for practical use on the agricultural fields. © Published under licence by IOP Publishing Ltd. | Ali, M.; Islam, M.N.; Reza, M.N.; Hong, J.G.; Gulandaz, M.A.; Chung, S.O. | Department of Agricultural Machinery Engineering, Graduate School, Chungnam National University, Daejeon, 34134, South Korea; Department of Agricultural Machinery Engineering, Graduate School, Chungnam National University, Daejeon, 34134, South Korea, Department of Smart Agricultural Systems, Graduate School, Chungnam National University, Daejeon, 34134, South Korea; Department of Agricultural Machinery Engineering, Graduate School, Chungnam National University, Daejeon, 34134, South Korea, Department of Smart Agricultural Systems, Graduate School, Chungnam National University, Daejeon, 34134, South Korea; Department of Bio-Industrial Machinery Engineering, Graduate School, Kyungpook National University, Daegu, 37224, South Korea; Department of Smart Agricultural Systems, Graduate School, Chungnam National University, Daejeon, 34134, South Korea; Department of Agricultural Machinery Engineering, Graduate School, Chungnam National University, Daejeon, 34134, South Korea, Department of Smart Agricultural Systems, Graduate School, Chungnam National University, Daejeon, 34134, South Korea | 57219292586; 57218177002; 57204066445; 57205186811; 57079072800; 7404293469 | sochung@cnu.ac.kr; | IOP Conference Series: Earth and Environmental Science | 1755-1307 | 924 | 1 | 2.24 | 2025-07-30 | 4 | English | Final | 2021 | 10.1088/1755-1315/924/1/012017 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Article | Analysis of Surface Urban Heat Island and Land Surface Temperature Using Deep Learning Based Local Climate Zone Classification: A Case Study of Suwon and Daegu, Korea | Urbanization increases the amount of impervious surface and artificial heat emission, resulting in urban heat island (UHI) effect. Local climate zones (LCZ) are a classification scheme for urban areas considering urban land cover characteristics and the geometry and structure of buildings, which can be used for analyzing urban heat island effect in detail. This study aimed to examine the UHI effect by urban structure in Suwon and Daegu using the LCZ scheme. First, the LCZ maps were generated using Landsat 8 images and convolutional neural network (CNN) deep learning over the two cities. Then, Surface UHI (SUHI), which indicates the land surface temperature (LST) difference between urban and rural areas, was analyzed by LCZ class. The results showed that the overall accuracies of the CNN models for LCZ classification were relatively high 87.9% and 81.7% for Suwon and Daegu, respectively. In general, Daegu had higher LST for all LCZ classes than Suwon. For both cities, LST tended to increase with increasing building density with relatively low building height. For both cities, the intensity of SUHI was very high in summer regardless of LCZ classes and was also relatively high except for a few classes in spring and fall. In winter the SUHI intensity was low, resulting in negative values for many LCZ classes. This implies that UHI is very strong in summer, and some urban areas often are colder than rural areas in winter. The research findings demonstrated the applicability of the LCZ data for SUHI analysis and can provide a basis for establishing timely strategies to respond urban on-going climate change over urban areas. | Lee, Yeonsu; Lee, Siwoo; Im, Jungho; Yoo, Cheolhee | Ulsan Natl Inst Sci & Technol, Dept Urban & Environm Engn, Ulsan, South Korea; Kyungpook Natl Univ, Sch Convergence & Fus Syst Engn, Daegu, South Korea | Yoo, Cheolhee/GYV-1185-2022; Im, Jungho/K-6257-2017 | 57365949500; 57366668300; 9036557400; 57366379900 | ersgis@unist.ac.kr; | KOREAN JOURNAL OF REMOTE SENSING | KOREAN J REMOTE SENS | 1225-6161 | 2287-9307 | 37 | 5 | ESCI | REMOTE SENSING | 2021 | N/A | 0.67 | 2025-07-30 | 5 | 8 | Words; Local Climate Zone; Deep Learning; Convolutional Neural Network; Urban Heat Island; Urban Climate | SEASONAL VARIABILITY; WAVES; EXPANSION; SATELLITE; HEALTH; IMPACT; COVER | Convolutional neural network; Deep learning; Local climate zone; Urban climate; Urban heat island | Korean | 2021 | 2021-10 | 10.7780/kjrs.2021.37.5.3.9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Analysis of Teacher Understanding After Adapting Collaborative Problem-Solving for Character Competence (CoProC) Program on Science Education | Science teachers in elementary schools and secondary schools recognize the necessity of character education, feeling difficulties such as evaluation methods, mood of competition, extra work and lack of time according to previous research, which were based on answers from science teachers not experiencing character education. As a rare study of teacher experiencing, previous researches didn't fully address the problems and suggestions about adopting character education in science classrooms. This study is about teacher practice of character education on site with the CoProC (Collaborative Problem-Solving for Character Competence) program in science classes with which other previous studies shed new light. Five teachers, adapting the CoProC program in their science classes, participated in two interviews, sharing their student achievement in character education. Results showed that student achievement was high when their teacher had experienced the training program, development, and classes of CoProC rather than their normal teaching career. Teacher recognition on the aims of CoProC influenced difficulties, evaluation, and feedback. | Kang, Eugene; Park, Jihun; Park, Jongseok; Nam, Jeonghee | Pusan Natl Univ, Dept Chem Educ, Busan 46241, South Korea; Pusan Natl Univ, Dept Phys Educ, Busan 46241, South Korea; Kyungpook Natl Univ, Dept Chem Educ, Daegu 41566, South Korea | 57217154510; 57225161946; 57022500800; 49461696200 | jhnam@pusan.ac.kr; | JOURNAL OF THE KOREAN CHEMICAL SOCIETY-DAEHAN HWAHAK HOE JEE | J KOREAN CHEM SOC | 1017-2548 | 2234-8530 | 65 | 2 | ESCI | CHEMISTRY, MULTIDISCIPLINARY | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | Character education; Teacher recognition; Science education; Collaborative problem solving | Character education; Collaborative problem solving; Science education; Teacher recognition | Students; Collaborative problem solving; Elementary schools; Evaluation methods; Science classroom; Science education; Secondary schools; Student achievement; Teacher practices; Personnel training | Korean | 2021 | 2021-04-20 | 10.5012/jkcs.2021.65.2.133 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Review | Analysis of the Possibility of Achieving the Purpose of Newton’s Second law Experiment Presented in the 2015 Revised Curriculum Physics I Textbooks | This study was conducted to determine if Newton’s second law experiment presented in the 2015 revised curriculum physicsⅠ textbooks can achieve the purpose of the experiment. For this purpose, Newton’s second law experiments presented in eight kinds of physicsⅠ textbooks were classified based on the method used to apply a force to an object, and experiments were performed to obtain real data. As a result of the study, all textbooks will have difficulty in deriving the desired goal from the textbook when the currently presented method is used. Specifically, in the experiment using elastic force, a specific method for constant external force needs to be proposed. In addition, in the experiment using the gravity of weight, it seems to be necessary to consider the error from the frictional force. In conclusion, we need to carefully examine if the experiments in the textbook can achieve their purposes. In particular, performing experiments involving Newton’s second law is difficult; therefore, it is necessary to consider what is the best way to deal with Newton’s second law experiment in a textbook. © 2021 The Korean Physical Society.
