| ○ | ○ | Article | The Primary Process and Key Concepts of Economic Evaluation in Healthcare | Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies. | Kim, Younhee; Kim, Yunjung; Lee, Hyeon-Jeong; Lee, Seulki; Park, Sun-Young; Oh, Sung-Hee; Jang, Suhyun; Lee, Taejin; Ahn, Jeonghoon; Shin, Sangjin | Inha Univ, Coll Med, Dept Social Med, Incheon, South Korea; Natl Evidence Based Healthcare Collaborating Agcy, Div Healthcare Technol Assessment Res, Seoul, South Korea; VIAplus, Suwon, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Coll Pharm, Community Based Intelligent Novel Drug Discovery E, Daegu, South Korea; Gachon Univ, Coll Pharm, Incheon, South Korea; Gachon Univ, Gachon Inst Pharmaceut Sci, Incheon, South Korea; Seoul Natl Univ, Grad Sch Publ Hlth, Dept Publ Hlth Sci, Seoul, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul, South Korea; Natl Evidence Based Healthcare Collaborating Agcy, Div Healthcare Technol Assessment Res, 400 Neungdong ro, Seoul 04933, South Korea | ; Lee, Yeoun Joo/AGP-1813-2022; Ahn, Jeonghoon/CAA-1956-2022; Kim, Younhee/HKN-5117-2023 | 56196104200; 56665462200; 56477500000; 57933363100; 59443979800; 57188550994; 38861740500; 55574232410; 8855402200; 57201964364 | jshin@neca.re.kr; | JOURNAL OF PREVENTIVE MEDICINE & PUBLIC HEALTH | 1975-8375 | 2233-4521 | 55 | 5 | 0.58 | 2025-06-25 | 8 | 10 | Economic evaluation; Medical cost; Quality-adjusted life year; Decision trees; Markov model; Incremental cost-effective ratio | COST-OF-ILLNESS | Decision trees; Economic evaluation; Incremental cost-effective ratio; Markov model; Medical cost; Quality-adjusted life year | Cost-Benefit Analysis; Delivery of Health Care; Humans; Pharmaceutical Preparations; Quality-Adjusted Life Years; calculation; comparative effectiveness; controlled study; cost effectiveness analysis; cost utility analysis; decision making; decision tree; economic evaluation; health care policy; human; Markov chain; mortality; outcome assessment; productivity; quality adjusted life year; review; sensitivity analysis; survival rate; uncertainty; article | English | 2022 | 2022-09 | 10.3961/jpmph.22.195 | 바로가기 | 바로가기 | 바로가기 | ||||||||
| ○ | Note | The prognostic significance of re-do surgery for recurrent and metastatic distal bile duct cancers after curative resection: A single center experience | Background: Metastatectomy for particular type of cancers has been known to have positive prognostic significance. Recently, metastectomy of pancreas cancer also has been increasingly reported. However, for bile duct cancer, the prognostic effect of re-do surgery was rarely reported. In addition to the paucity of results of metastatectomy, the altered gastrointestinal structure and sever adhesion following pancreaticoduodenectomy make surgeons to hesitate to do re-do surgery. In this study, we reviewed our experiences of re-do surgery for the patients with recurrent or metastatic bile duct cancer. Methods: We reviewed the medical records of the 123 consecutive patients who underwent metastatectomy following pancreaticoduodenectomy (PD) or Bile duct resection (BDR) in single institution from 2011 to 2019 retrospectively. Among 123 patients, 98 patients were analyzed for survival excluding palliative surgery, minimally invasive surgery, and surgery for combined primary cancers. Results: The median follow period was 42 month. (22–69 months) and overall 5-year survival rate for the 98 patients was 48.7%. The rate of metastatic diseases was 49% (n = 48). Median disease free survival of the all 48 patients with metastasis was 12 months (7–25 months). Eight patients among 48 patient with metastatic diseases underwent re-do surgery (n = 8, 16.7%). The re-do surgery included 2 cases of left hepatectomy with re-hepaticojejunostomy, 2 cases of extended left hepatectomy, 3 cases of segmentectomy, and one case of excision for metastatic nodule of lung. The other treatment included chemotherapy (n = 17, 35.4%), Radiotherapy (n = 1, 2.1%), and supportive care (n = 22, 45.9%). The median survival time after re-do surgery were longer than those of the other patients without redo surgery (22 months; range, 11–35 months vs. 6 months; range, 3–10 months, p-value < 0.01). Conclusions: Re-do surgery for the recurrent or metastatic disease following potentially curative resection for bile duct cancer can prolong the survival. © The Korean Association of Hepato-Biliary-Pancreatic Surgery. | Jeon, Hyun Jeong; Kim, Sang Geol; Kwon, Hyung Jun; Hwang, Yoon Jin | Department of Surgery, Kyungpook National University Chilgok Hostpital, Daegu, South Korea; Department of Surgery, Kyungpook National University Chilgok Hostpital, Daegu, South Korea; Department of Surgery, Kyungpook National University Chilgok Hostpital, Daegu, South Korea; Department of Surgery, Kyungpook National University Chilgok Hostpital, Daegu, South Korea | 57266297900; 21735842600; 59579184900; 59782503700 | ksg@knu.ac.kr; | Annals of Hepato-Biliary-Pancreatic Surgery | 2508-5778 | 26 | 0 | 2025-06-25 | 0 | English | Final | 2022 | 10.14701/ahbps.2022s1.bp-pp-1-1 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | The quality characteristics of plant-based garlic mayonnaise using chickpea aquafaba with different ultrasonic treatment time | Recently, there has been a growing trend to replace animal ingredients used in food with plant-based alternatives for health, environment, and animal welfare. In this study, chickpea aquafaba was used as emulsifier for mayonnaise, and the effect of ultrasound on aquafaba and plant-based mayonnaise was investigated. Aquafaba with chickpea [1:2 (w/w)] was treated by ultrasound in 40 kHz and 200 W for 0, 30, 60, and 90 min. The emulsion property and quality of aquafaba with ultrasonic treatment time (UTT) and plant-based mayonnaise (UTT0, UTT30, UTT60, and UTT90) were analyzed, and compared with mayonnaise using egg yolk (CONT). As the UTT of aquafaba, the protein solubility increased, but emulsion activity index was highest in sample treated for 30 min (p<0.05). These results affected plant-based mayonnaise. The microstructure was confirmed that oil droplet of plant-based mayonnaises were larger than CONT, and size of oil droplet decreased by UTT. The emulsion stability of plant-based mayonnaises were about 7-11% lower than CONT, and among plant-based mayonnaises, UTT30 was the highest at 81.30%, and UTT60 and UTT90 were the lowest. Plant-based mayonnaise had higher viscosity and overall acceptability than CONT, and viscosity decreased by UTT. Optimal UTT had a beneficial effect on the emulsion property of aquafaba and mayonnaise, and a positive role can be expected as plant-based alternative emulsifier. © 2022 The Korean Society of Food Preservation. | Kim, Jungsoo; Kim, Jiyoon; Jeong, Saeul; Kim, Minhyun; Park, Sanghyeok; Kim, Insun; Nam, Inju; Park, Junyeong; Moon, Kwang-Deog | School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea; School of Food Science and Technology, Kyungpook National University, Daegu, 41566, South Korea, Food and Bio-Industry Research Institute, Kyungpook National University, Daegu, 41566, South Korea | 57211108486; 57208110209; 57219605598; 57226597969; 57226601564; 57838543900; 57837906500; 57837906600; 55999192900 | kdmoon@knu.ac.kr; | Korean Journal of Food Preservation | 1738-7248 | 29 | 3 | 0.26 | 2025-06-25 | 3 | aquafaba; emulsion property; plant-based mayonnaise; quality characteristics; ultrasonic treatment time | Korean | Final | 2022 | 10.11002/kjfp.2022.29.3.381 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | The quality characteristics of plant-based muffins prepared with different contents of Actinidia arguta powder | Despite the high intake convenience and functionality of Actinidia arguta, its practical utilization remains limited; therefore, the development of new products is necessary to increase the industrial significance of Actinidia arguta. Also, as the vegetarian population increases rapidly, various plant-based products are required. This study, the most optimum contents of Actinidia arguta powder (AP) was selected by analyzing the quality of plant-based muffins added by different amounts of AP (0%, 10%, 15%, and 20% (w/w) based on wheat flour). The muffin height and volume decreased significantly by adding AP. AP10 exhibited the lowest water holding capacity of flour, which affected the moisture content, baking loss, and yield. As AP increased, pH decreased and DPPH radical scavenging increased (p<0.05). In sensory evaluation AP10, and AP15 presented the high scores, while AP20 was the lowest. Smell scores was increased by adding AP. AP15 had the highest in appearance and texture. As a result, 15% of AP is the optimum concentration for producing plant-based muffins. Although lower in appearance quality than AP0, AP15 has satisfied preferences and functional needs. It is expected to increase the consumption of Actinidia arguta.

| ○ | Article | The Relationship Between the Korean Adults Diet Evaluated Using Dietary Quality Indices and Metabolic Risk Factors: Based on the 2016 ~ 2019 Korea National Health and Nutrition Examination Survey | Objectives: This study was designed to investigate the relationship between metabolic risk factors, Index of Nutrition Quality, and the dietary quality index score of Korean adults. Methods: The subjects were 18,652 Korean adults aged 19 years or older (7,899 males, 10,753 females) who participated in the 2016-2019 Korea National Health and Nutrition Examination Survey. Subjects were divided into normal, pre-metabolic syndrome, and metabolic syndrome (MetS) groups according to the number of their metabolic risk factors. Data were analyzed using the SPSS program. Results: About 44.7% of men in the MetS group were at least college graduates (P < 0.001), whereas 52.0% of women in the MetS group were middle school graduates or lower (P < 0.001). The frequency of fruit and dairy products intake tended to decrease as the number of metabolic risk factors increased in both men and women (P for trend < 0.001). As the number of metabolic risk factors decreased, the frequency of grain intake tended to decrease in men (P for trend < 0.001) while the frequency of intake of red meat (P for trend = 0.001), poultry (P for trend < 0.001), and eggs (P for trend < 0.001) decreased in women. The total scores of Diet Quality Index-International (DQI-I) (men P < 0.001, women P < 0.01) and Korean Healthy Eating Index (KHEI) (men and women P < 0.001) were significantly lower in the MetS group compared to the other groups, and the total score of DQI-I and KHEI tended to decrease as the number of metabolic risk factors increased. Conclusions: Dietary quality evaluation using various indices can provide more information on the dietary problems related to metabolic risk factors. Nutrients and foods that have been confirmed to be related to metabolic risk factors can be used to develop dietary guidelines for the nutritional management of metabolic diseases. © 2022 Korean Society of Community Nutrition. | Ding, Chong-Yu; Park, Pil-Sook; Park, Mi-Yeon | Department of Food Science and Nutrition, Kyungpook National University, Daegu, South Korea; Department of Food Science and Nutrition, Kyungpook National University, Daegu, South Korea; Department of Food and Nutrition, Gyeongsang National University, Jinju, South Korea | 58828092100; 55909315600; 36871206400 | mypark@gnu.ac.kr; | Korean Journal of Community Nutrition | 2951-3146 | 27 | 3 | 0.24 | 2025-06-25 | 2 | dietary quality index; food group; metabolic risk factor | Korean | Final | 2022 | 10.5720/kjcn.2022.27.3.223 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | The Research of Ce3+-doped Lu2Gd1Ga2Al3O12 Phosphor for X-ray Imaging | Ce3+-doped Lu2Gd1Ga2Al3O12 phosphor is fabricated by solid-state reaction method using an electric furnace at 1500 ◦C for 12 hours and measured by an X-ray diffractometer (XRD) and a field emission scanning electron microscope (FE-SEM) to confirm the crystalline structure. The luminescence properties for UV and X-ray is investigated using X-ray and UV sources, respectively. The emission wavelength of the Ce3+-doped Lu2Gd1Ga2Al3O12 phosphor for UV and X-ray is confirmed at 525 nm because of 2D5/2 to 2F5/2 transition. This wavelength is coincident with yellow color in the CIE chromaticity diagram. The rare earth element-containing phosphors have a high absorption efficiency for X-ray and gamma-ray because of their high atomic Z numbers (Zeff = 55); therefore, they have an advantage for medical imaging fields using X-ray and gamma-ray. © 2022 The Korean Physical Society.

| ○ | Book chapter | The role of autonomous demand growth in a neo-Kaleckian conflicting-claims framework’ | This paper incorporates the role of an independently growing autonomous demand component into a neo-Kaleckian model of growth and distribution where the distribution of income is fully endogenized. A peculiar feature of these autonomous expenditures is that in contrast to investment they are noncapacity creating. The model presents the combined dynamic effects of a conflicting-claims theory of inflation, the Sraffian supermultiplier, the Harrodian instability mechanism and mechanisms based on a reserve army of labor effects. The key features of the model include the convergence towards a long-run steady state where the normal rate of utilization of capacity is being attained and where stable rates of employment and inflation are being achieved. Despite the achievement of a fully-adjusted position, the model vindicates some of the main Keynesian or Kaleckian tenets, in the sense that both the average rates of capital accumulation and capacity utilization decrease during the whole traverse after either an increase in the marginal propensity to save out of profits, an upward adjustment in the claims on profits, or an enhancement of the bargaining power of firms relative to workers. © Marc Lavoie 2022. | Nah, Won Jun; Lavoie, Marc | School of Economics and Trade, Kyungpook National University, Daehakro, Bukgu, Daegu, South Korea; University of Sorbonne Paris Cité, University of Paris 13, CEPN, 99 ave.Jean-Baptiste Clément, Villetaneuse, 93430, France | 36497335900; 35775352400 | Post-Keynesian Growth Theory:Selected Essays | 0 | 2025-06-25 | 0 | Aggregate demand and supply; Autonomous expenditures; Capacity utilization; Conflicting-claims; Growth; Neo-Kaleckian; reconciliation | English | Final | 2022 | 바로가기 | ||||||||||||||||||||||
| ○ | ○ | Article | The Role of Maternal Grandmothers' Childcare Provision for Korean Working Adult Daughters | Despite the Korean government's investment in childcare facilities for dual-earner households, maternal grandmothers are increasingly taking on the responsibility of caring for their grandchildren. This trend is examined in the current research. While many studies have been conducted on grandparents' experiences providing childcare for their grandchildren, significantly less research has been conducted on adult daughters' experiences with their mothers' childcare provision. This study utilized the concepts of intergenerational solidarity and a life-course approach to understand the experiences of 24 working adult daughters in Korea (ages 30-43) whose mothers provide childcare. Three major themes were identified following a grounded theory approach: gratitude vs. guilt, dependence vs. independence, and closeness vs. disagreement. The results indicated that adult daughters were found to have ambivalence toward their mothers, reflecting the lack of alternative options for childcare. The results from this study suggest that not only improving the quality of public childcare services, but also diversifying services to reflect the needs of dual-income families. | Jeon, Sesong; Walker, Katie | Kyungpook Natl Univ, Coll Human Ecol, Sch Child Studies, Child & Family Studies, Daegu 41566, South Korea; Eastern Washington Univ, Childrens Studies Child Life & Hlth Program, Cheney, WA 99004 USA | 57216944363; 57958778300 | ssjeon@knu.ac.kr; | INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH | 1660-4601 | 19 | 21 | 0.18 | 2025-06-25 | 1 | 2 | childcare; working adult daughter; intergenerational solidarity model; ambivalence | AMBIVALENCE; SOLIDARITY; FAMILY | ambivalence; childcare; intergenerational solidarity model; working adult daughter | Adult; Adult Children; Child; Child Care; Female; Grandparents; Humans; Intergenerational Relations; Mothers; Republic of Korea; South Korea; adult; child care; trend analysis; adult; ambivalence; article; child care; female; grandchild; grandmother; grounded theory; guilt; human; intimacy; Korea; life course perspective; solidarity; adult child; child; child care; grandparent; human relation; mother; procedures; South Korea | English | 2022 | 2022-11 | 10.3390/ijerph192114226 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | The role of the eco-corridor for the walking beetles in Chupungryeong, Korea | Eco-corridors are essential for walking wild animals to move and connect with ecosystems between fragmented habitats. This study aimed to determine the role of the eco-corridor and the biodiversity of ground beetles near eco-corridors constructed between areas divided for a prolonged period. As a center of the Chupungryeong eco-corridor, Bongsan-myeon, Gimcheon-si, Gyeongsangbuk-do on the Gyeongbu expressway, four sites were examined. To confirm the movement of beetles on the bridge, we used the capture-recapture method by marking specimens around 5 cm belonging to Carabus jan-kowskii, Eucarabus sternbergi, and Carabus semiopacus. On the other hand, pitfall traps in each opposite area were used to investigate the biodiversity of ground beetles. Our results indicated that ground beetles moved between separated habitats using eco-corridors. In addition, the collections showed different diversities at each site. These results confirmed the important role of the eco-corridor in walking animals, although more detailed research is required. Additionally, these results provide baseline data for future eco-corridor construction (c) 2022 National Science Museum of Korea (NSMK) and Korea National Arboretum (KNA), Publishing Services by Elsevier.

| ○ | Article | The Second Reidemeister Moves and Colorings of Virtual Knot Diagrams | Two virtual knot diagrams are said to be equivalent, if there is a sequence S of Reidemeister moves and virtual moves relating them. The difference of writhes of the two virtual knot diagrams gives a lower bound for the number of the first Reidemeister moves in S. In previous work, we introduced a polynomial (qK)(t) for a virtual knot diagram K which gave a lower bound for the number of the third Reidemeister moves in the sequence S. In this paper we define a new polynomial from a coloring of a virtual knot diagram. Using this polynomial, we give a lower bound for the number of the second Reidemeister moves in S. The polynomial also suggests the design of the sequence S. | Jeong, Myeong-Ju; Kim, Yunjae | Korea Sci Acad, Dept Math, 111 Baekyang Guanmun Ro, Busan 47162, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea | mjjeong@ksa.kaist.ac.kr;kimholzi@gmail.com; | KYUNGPOOK MATHEMATICAL JOURNAL | KYUNGPOOK MATH J | 1225-6951 | 0454-8124 | 62 | 2 | ESCI | MATHEMATICS | 2022 | 0.7 | 0 | virtual knot; Reidemeister moves; coloring; knot polynomial | English | 2022 | 2022-06 | 10.5666/kmj.2022.62.2.347 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Conference paper | The Silicon Vertex Detector of the Belle II Experiment | The Belle II experiment started taking data at the SuperKEKB collider in spring 2019. As part of the inner tracker system, the silicon vertex detector (SVD) has been operating reliably. It provided good data quality, a good signal-to-noise ratio, an excellent hit efficiency greater than 99% and precise spatial resolution, which result in good tracking efficiency. The current occupancy, which is dominated by beam-background hits, is around 0.5% in the innermost layer and does so far not cause problems to the SVD data reconstruction. Due to the estimated increase in occupancy at higher luminosity in the next years, specific strategies aiming to preserve the tracking performance were developed and tested on data. Strip noise, sensor currents and depletion voltages have been measured to check for the first effects of radiation damage. So far no harmful impact on the detector performance has been observed. Extrapolations for the next years do not imply upcoming problems, although these background estimates are still affected by large uncertainties.

| ○ | Article | The Study of Crystallization of Cu2ZnSnS4 Thin Film Using Low-cost Diode Laser (408 nm) | In this study, Cu2ZnSnS4 (CZTS) thin films were fabricated using a solution process and a laser annealing process. The physical properties, including morphology and crystallinity, and optical properties of the films were investigated according to laser treatment time. The precursors (CuCl2, ZnCl2, SnCl2, and thiourea), solvent (2-methoxyethanol), and stabilizer (ethanolamine) were used to prepare the CZTS solution. The CZTS films were fabricated on glass substrates using the spray deposition method and annealed using a diode laser (408 nm, 500 mW) under vacuum conditions. The laser-annealed CZTS films had a kesterite structure with good crystallinity, and the optical bandgaps of the CZTS thin films were 0.99 – 1.11 eV. However, secondary crystalline phases were found in the thin film with a processing time of 500 ms. These results meant that optimization of the laser processing time was necessary. In conclusion, the laser annealing process had the potential to fabricate high-quality thin films without using a vacuum process, and laser-annealed CZTS thin films could be applied to high-efficiency solar cells. © 2022 The Korean Physical Society.

| ○ | Article | THE UNIT BALL OF BILINEAR FORMS ON R2 WITH A ROTATED SUPREMUM NORM | Let 0 ≤ θ <π2andl2∞,θ be the plane with the rotated supremum norm { } ∥(x, y)∥∞,θ = max |(cosθ)x + (sinθ)y|, |(sinθ)x − (cosθ)y|. We devote to the description of the sets of extreme, exposed and smooth points of the closed unit balls of L(2 l∞,θ2) and L s(2 l∞,θ2), where L(2 l∞,θ2) is the space of bilinear forms on l∞,θ2,and Ls(2 l∞,θ2) is the subspace of L(2 l∞,θ2) consisting of symmetric bilinear forms. Let F = L(2 l∞,θ2) or Ls(2 l∞,θ2). First we classify the extreme and exposed points of the closed unit ball of F. We also show that every extreme point of the closed unit ball of F is exposed. It is shown that ext BLs(2 l∞,θ2) = ext BL(2 l∞,θ2) ∩Ls (2 l∞,θ2) and expBLs(2 l∞,θ2) = exp BL(2 l∞,θ2) ∩ Ls (2 l∞,θ2). We classify the smooth points of the closed unit ball of F. It is shown that sm BL(2 l∞,θ2) ∩Ls (2 l∞,θ2)⊊ smBLs(2 l∞,θ2). As corol-lary we extend the results of [18, 35]. © 2022, Transilvania University of Brasov 1.

| ○ | Article | The use of commercial wine yeast Saccharomyces cerevisiae EC1118 for cassava ethanol production at high solids loading | Cassava is one of the most commonly imported raw materials for ethanol fermentation for the manufacture of food-grade distilled spirits in Korea. In cassava-producing countries, such as the Lao PDR, cassava can be considered low-price biomass for the production of bioethanol. In this study, the commercial wine yeast Saccharomyces cerevisiae EC1118 was tested for ethanol fermentation using cassava powder at a high solids loading (30%, w/v). α-Amylase and glucoamylase were used for the hydrolysis of cassava starch into glucose. To identify a suitable fermentation process for cassava, separate hydrolysis and fermentation (SHF) and simultaneous saccharification and fermentation (SSF) were compared. From the complete enzyme hydrolysis of cassava, 254.1 g/L of glucose was obtained. SSF showed higher ethanol titer during the first 12 h of fermentation, but SHF showed a higher ethanol titer after 24 h of fermentation. Finally, there was no significant difference between SHF and SSF in the final ethanol titer after 48 h fermentation (133.6 and 130.6 g/L, respectively). In summary, both SHF and SSF are applicable for ethanol production with high solid cassava using wine yeast EC1118 under the test conditions.

| ○ | Article | The Use of Unsupervised Machine Learning for the Attenuation of Seismic Noise | When acquiring seismic data, various types of simultaneously recorded seismic noise hinder accurate interpretation. Therefore, it is essential to attenuate this noise during the processing of seismic data and research on seismic noise attenuation. For this purpose, machine learning is extensively used. This study attempts to attenuate noise in prestack seismic data using unsupervised machine learning. Three unsupervised machine learning models, N2NUNET, PATCHUNET, and DDUL, are trained and applied to synthetic and field prestack seismic data to attenuate the noise and leave clean seismic data. The results are qualitatively and quantitatively analyzed and demonstrated that all three unsupervised learning models succeeded in removing seismic noise from both synthetic and field data. Of the three, the N2NUNET model performed the worst, and the PATCHUNET and DDUL models produced almost identical results, although the DDUL model performed slightly better. | Kim, Sujeong; Jun, Hyunggu | Kyungpook Natl Univ, Dept Geol, 80 Daehak Ro, Daegu, South Korea | ; Kim, Ik-Sang/J-5425-2012; Jun, Hyunggu/ABT-7172-2022 | hgjun@knu.ac.kr; | GEOPHYSICS AND GEOPHYSICAL EXPLORATION | GEOPHYS GEOPHYS EXPL | 1229-1064 | 2384-051X | 25 | 2 | ESCI | GEOCHEMISTRY & GEOPHYSICS | 2022 | 0.4 | 2 | seismic noise; seismic data processing; unsupervised machine learning; noise attenuation | VELOCITY ESTIMATION | Korean | 2022 | 2022 | 10.7582/gge.2022.25.2.071 | 바로가기 | 바로가기 | 바로가기 |
