| ○ | Article | Firm life cycle and stock price informativeness on future earnings* | This study examines the effect of firm life cycle on stock price informativeness of future earnings. We define firm life cycle according to Dickinson’s (2011) cash flow pattern and measure stock price informativeness of future earnings by the future earnings response coefficient (henceforth FERC), which is the association between current period stock returns and future earnings. Useful accounting information reduces uncertainty in forecasting future earnings, so that future earning information is properly reflected in the current stock price. This means high useful accounting information shows high FERC. Therefore, we expect that firms in the mature stage have higher FERC than firms in other life cycle stages. The results show that firms in mature stage have a higher FERC than firms in other life cycles, which means accounting information of firms in maturity is more useful. And we compare the FERC across life cycle stages and find that the FERC of firms in the introduction is significantly lower than that of firms in other life cycles. The contribution of this study is that the usefulness of accounting information differs according to the life cycle of the firms. The life cycle can be identified by the cash flow patterns provided in the cash flow statement, making it a practically convenient method for investors. © 2020, Korean Accounting Association.

| ○ | Article | First report of phytophthora leaf blight and vine rot of kudzu (Pueraria lobata) in Korea | A disease causing leaf blight and vine rot was recognized on kudzu plants (Pueraria lobata) in Korea since 1991. A species of Phytophthora has been repeatedly isolated from the infected leaves. Identification in species level of the Phytophthora sp. remained unsolved. An isolate, KACC 47616 originally collected from Manchon Park in Daegu, has been kept in our laboratory. In 2013, three new isolates, KACC 47617 and KACC 47618 from Yeongyang and KACC 47619 from Gunwi in Gyeongbuk province, were collected and examined to classify up to species level by characterizing morphology, response to temperature and phylogenetic relationship. On the basis of morphological characters such as the nature of hyphal swelling, sporangia and sex organs, absence of chlamydospore production, optimum temperature for mycelial growth, and internal transcribed spacer rDNA and cytochrome oxidase subunit 1 sequence analysis of the pathogen, the causal fungus of kudzu plant was identified as Phytophthora asiatica. © 2020 Storia della Donne.

| ○ | Article | First report of rust disease caused by Puccinia phragmitis on Rumex japonicus in Korea | Red spots symptoms were observed on the leaves of Rumex japonicus Houtt. in Goesan, Korea, in May 2019. Diseased leaf showing red spot and white-colored sori were found behind of diseased leaves. Aeciospores were confirmed and observed using a stereomicroscope, light microscope, and scanning electron microscope. They were globose or ovoid and measured 19.0-24.4×19.0-24.5 μm, with verrucae ornamentation. For the phylogenetic analysis, partial of large subunit rDNA region and cytochrome c oxidase subunit III were sequenced. As a result, the isolated fungus species showed high similarities with Puccinia prizeliana. Based on the previous report, morphological characters, phylogenetic analysis, it was confirmed as Puccinia phragmitis which have not been reported in Korea, and we firstly report this fungal agent on R. japonicus as P. phragmitis in Korea. © 2020 Research in Plant Disease.

| ○ | Article | Flexible post-process machining of the directed energy deposition (DED) printed part through the on-machine measurement | The directed energy deposition (DED) process has been used for enhancement of the mechanical property, repair, and part manufacturing. Post-process machining is required due to the low quality of the DED printed part. Even if the part is printed under similar conditions, dimensional variations occur frequently due to the accumulation of small printing errors. Due to tool overfeeding and the occurrence of the non-cutting area due to this variation, the quality of the finished part is not guaranteed. Therefore, the post-process machining should be carried out considering the actual printed part shape. Herein, the flexible post-process machining is proposed by utilizing the shape information through the on-machine measurement (OMM) of DED printed parts. The process margin for machining the design shape is calculated through the OMM of the geometric dimension of the printed part. Feedrate (Override) and machining path of each printing parts are flexibly determined depending on the process margin. This technique is applied to the pocket shape part printed with STS 316L material, and the rough and finish machining conditions are established. Rough machining time was reduced by adjusting the feedrate flexibly. The final form of accuracy and surface roughness were achieved under 30 and 0.25 μm, respectively.

| ○ | ○ | Article | Flora characteristics of vascular plants in the Geomun Oreum, UNESCO World Natural Heritage Site in Jeju Island, Korea | A study on the flora of Geomun Oreum, designated as a UNESCO World Natural Heritage Site, was surveyed in 2019. Vascular plants in this area revealed 310 taxa belonging to 90 families, 210 genera, 279 species, one subspecies, 27 varieties, and three formas. The Geomun Oreum showed low mean annual temperature, but it was confirmed that the emergence of warm-temperate plant species and evergreen broad-leaved forests was prominent. These results were interpreted to be due to a great deal of precipitation, many frost-free days, and the difference between the highest and lowest temperatures depending on the geographical characteristics of Geomun Oreum. Geomun Oreum is evaluated as a relatively natural habitat given the limited access of visitors and management, but it was confirmed that Sedum tosaense, a critically endangered species of the rare plants designated by the International Union for Conservation of Nature, requires conservation plans in the area.

| ○ | Article | Flow analysis using the schlieren method in electrospray deposition | In this study, four polar solvents with different properties (methanol, ethanol, 2-propanol, distilled water) were sprayed at different substrate temperatures by using the electrospray method. The flow changes for each solvent were visualized by using the Schlieren method, and the acquired images were analyzed by using a two-dimensional fast Fourier transformation (2D-FFT) technique. The applied voltage at cone-jet mode showed different values depending on the type of solvent, and the spraying angle at the cone-jet mode was closely related to the viscosity of the solvent. The flow due to substrate heating was mainly due to a convection process, and strong flows were observed on the heating plate with increasing temperature. We confirmed that these flows could be easily visualized by using the Schlieren technique and that the acquired images could be qualitatively analyzed by using 2D-FFT. Consequently, the 2D-FFT technique is expected to be useful for the analysis of various flows, as well as the analysis of air flow. © 2020 The Korean Physical Society.

| ○ | Book chapter | Following the trail of the operator geometric mean | This paper traces the development of the theory of the matrix geometric mean in the cone of positive definite matrices and the closely related operator geometric mean in the positive cone of a unital C∗-algebra. The story begins with the two-variable matrix geometric mean, moves to the n-variable matrix setting, then to the extension to the positive cone of the C∗-algebra of operators on a Hilbert space, and even to general unital C∗-algebras, and finally to the consideration of barycentric maps on the space of integrable probability measures on the positive cone. Besides expected tools from linear algebra and operator theory, one observes a substantial interplay with operator monotone functions, geometrical notions in metric spaces, particularly the notion of nonpositive curvature, some probabilistic theory of random variables with values in a metric space of nonpositive curvature, and the appearance of related means such as the inductive and power means. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. | Lawson, Jimmie D.; Lim, Yongdo | Department of Mathematics, Louisiana State University, Baton Rouge, LA, United States; Department of Mathematics, Kyungpook National University, Taegu, South Korea | 7402258038; 55931749600 | lawson@math.lsu.edu; | Trends in Mathematics | 2297-0215 | 0.88 | 2025-06-25 | 2 | Contractive barycentric map; Geometric mean; Nonpositively curved metric spaces; Operator mean; Operator monotone function | English | Final | 2020 | 10.1007/978-3-030-53305-2_10 | 바로가기 | 바로가기 | ||||||||||||||||||

| ○ | Article | Formation of Nano/Micro Hierarchical Structures on Titanium Alloy Surface by a Novel Etching Solution | A new effective oxidative solution for titanium (Ti) surface etching was recently developed. The present in vitro study was aimed at determining the influence of shorter (than 240 min) treatment time on the surface characteristics of the Ti nano/micro hierarchical structures. Cylinder-shaped Ti grade 5 alloys were etched for 30, 60, 120, and 240 min at room temperature and cleaned successively with acetone, ethanol, and distilled water in an ultrasonic bath. The micro- and nano structures, surface roughness, dynamic wettability, and the surface elemental composition of the etched surfaces were evaluated. Nano/micro hierarchical structures, composed of micro-pits and nano-channels, were formed on the Ti surface through simple immersion in the oxidative solution. The findings suggest that the 120-min immersion yielded significant enhancement in the roughness and wettability of the Ti surfaces. | Kim, In-Hye; Im, Jae-Seung; Lee, Mun-Hwan; Min, Bong Ki; Son, Jun Sik; Hong, Min-Ho; Kwon, Tae-Yub | Kyungpook Natl Univ, Grad Sch, Dept Dent Sci, Daegu 41940, South Korea; Kyungpook Natl Univ, Grad Sch, Dept Med & Biol Engn, Daegu 41940, South Korea; Yeungnam Univ, Ctr Res Facil, Gyongsan 38541, South Korea; Korea Text Dev Inst, Daegu 41842, South Korea; Kyungpook Natl Univ, Inst Biomat Res & Dev, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 41940, South Korea | Kim, Eun/AAS-6706-2020 | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 7 | 2 | Implant; Titanium Surface; Etching; Hierarchical Structures | English | 2020 | 2020-07 | 10.1166/jnn.2020.17575 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | ○ | Article | Formation of Porous Oxide Layer on Stainless Steel by Anodization in Hot Glycerol Electrolyte | In this study, nanoporous iron oxide layers were fabricated by the anodization of 304 series stainless steel. K2HPO4/glycerol solution was used as an electrolyte for anodization. We investigated the anodization behavior according to various parameters such as electrolyte concentration, reaction temperature, applied voltage, and reaction time. As a result of anodization, we confirmed that the anodic growth rate of oxide layer on 304 series stainless steel increased with increasing the electrolyte temperature and applied potential. In order to form well-ordered porous nanostructures, the electrolyte temperature was at 160 degrees C, and the applied potential was at 30 V in 10 wt% K2HPO4/glycerol electrolyte. | Lee, Jaewon; Choi, Hyun-Kuk; Kim, Moon Gab; Lee, Yong Sei; Lee, Kiyoung | Kyungpook Natl Univ, Sch Nano & Mat Sci & Engn, 2559 Gyeonsang Daero, Sangju 37224, South Korea | Lee, Kiyoung/J-8680-2013 | 59830462300; 8550872100; 7406088151; 58365006000; 57219211501 | kiyoung@knu.ac.kr; | APPLIED CHEMISTRY FOR ENGINEERING | APPL CHEM ENG | 1225-0112 | 1228-4505 | 31 | 2 | ESCI | ENGINEERING, CHEMICAL | 2020 | N/A | 0.06 | 2025-06-25 | 3 | 1 | Anodization; Stainless steel; Porous structure; Hot glycerol electrolyte; K2HPO4 | FILMS; BEHAVIOR | Anodization; Hot glycerol electrolyte; K<sub>2</sub>HPO<sub>4</sub> ; Porous structure; Stainless steel | Korean | 2020 | 2020-04 | 10.14478/ace.2020.1015 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Conference paper | Frequency shift keying and error correction technique for robust electrostatic coupling intra-body communication | Intra body communication (IBC) is a wireless communication system for exchanging various kinds of digital information through wearable electronic devices and sensors. IBC using the human body as a transmission channel allows for wireless communication without transmitting radio frequency waves through the air. This paper discusses the results of experiments on electrostatic coupling of IBC based on frequency shift keying (FSK) and 1-bit error correction. The experimental results show that digital data modulated using square-waves as carrier signals can be successfully transmitted through the human body. In addition, when applying a 1-bit error correction algorithm, the byte error rate on receiver side is improved by about 3.5% compared to transmission without correction. © 2020 IEEE. | Cho, Seongho; Lee, Sanghoon; Park, Daejin | Advanced Development Team, LG Display, South Korea, Kyungpook National University, School of Electronics Engineering, South Korea; Carnavicom Co.

| ○ | Book chapter | Fungal secondary metabolites: A potential source of anticancer compounds | Not long ago, new industrial products were developed using fungal secondary metabolites. Fungi have numerous secondary metabolites such as terpenoids, xanthones, steroids, phenols, chinones, tetralones, cytochalasins, enniatins, benzopyrones, flavonoids, alkaloids, cardiac glycosides, tannins, and saponins. In recent years, cancer has become a dreadful disease all over the world, and more than 6 million new cases are reported every year. Fungi have tremendous chemical diversity, and they also play important roles in the development of numerous clinically useful anticancer agents. The productivity and vulnerability of novel metabolites from microorganisms make them essential, readily available, renewable, and everlasting sources of novel structures bearing pharmaceutical potential. Shrewdness from fungal research could provide substitute methods of natural product drug discovery that could be reliable, economical, and environmentally safe. © 2020 Elsevier B.V.

| ○ | Review | Gastrointestinal emergencies in neonates: What we should know | Newborn gastrointestinal tract emergency diseases include various disorders that occur anywhere along the digestive tract. Most of them are congenital malformations, not acquired diseases. Many of them cannot be confirmed on prenatal examination, and consequently, postnatal evaluation is required. Unlike adults, in newborn babies, detailed evaluations with computed tomography (CT) and magnetic resonance imaging (MRI) are often limited, so making the diagnosis based on early abdominal radiography is most important. Therefore, it is necessary to be familiar with the radiologic findings that may be seen on imaging studies. In addition, it is important to understand abdominal ultrasound and fluoroscopy findings, which can be used in addition to simple radiography and indications that can be used for further diagnosis and appropriate treatment. Therefore, this study describes and organizes the various imaging findings that may occur in neonatal gastrointestinal emergencies. © 2020 The Korean Society of Radiology. | Cho, Hyun-Hae; Lee, So Mi; You, Sun Kyoung | Department of Radiology, Ewha Womans University, Mokdong Hospital, Seoul, South Korea; Department of Radiology, School of Medicine, Kyungpook National University, Kyungpook National University Hospital, Daegu, South Korea; Department of Radiology, Chungnam National University, School of Medicine, Chungnam National University Hospital, Daejeon, South Korea | 56544900900; 56824903400; 56710939300 | picoai@yahoo.co.kr; | Journal of the Korean Society of Radiology | 1738-2637 | 81 | 4 | 0.11 | 2025-06-25 | 2 | Gastrointestinal Diseases; Infant; Newborn | Korean | Final | 2020 | 10.3348/jksr.2020.81.4.770 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Proceedings Paper | Generalized phase-shifting color digital holography | To measure object wave in digital holography, the phase-shifting technique is popular by changing the phase of the reference wave. A piezo actuator (PZT) is usually used as a device to shift the phase. In a case to obtain the phase information of color object with multiple wavelengths, four-step phase-shifting algorithm with quarter wavelength shift is not convenient since the amount of the phase shift is difference according to each wavelength. In this paper, the generalized four-step phase-shifting method is proposed and experimentally verified to obtain color digital hologram using an image sensor with a Bayer pattern for capturing interference pattern shifted phase by one PZT. | Jung, Minwoo; Jeon, Hosung; Kim, Beomjun; Lim, Sungjin; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect Engn, 80 Daehak Ro, Daegu 702701, South Korea | 57216159562; 56663784700; 57216150371; 56706721300; 10142501600 | jhahn@knu.ac.kr; | PRACTICAL HOLOGRAPHY XXXIV: DISPLAYS, MATERIALS, AND APPLICATIONS | 0277-786X | 1996-756X | 11306 | 0 | 2025-06-25 | 0 | 0 | Digital holography; color holography; phase shift | INTERFEROMETRY | Color holography; Digital holography; Phase shift | Color; Holograms; Phase shift; Color holography; Digital holography; Four-step phase-shifting; Interference patterns; Multiple wavelengths; Phase information; Phase-shifting technique; Quarter-wavelength; Holographic displays | English | 2020 | 2020 | 10.1117/12.2544640 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
