| ○ | Article | Laparoscopic right hepatectomy after portal vein embolization in hepatocellular carcinoma | Introduction: Portal vein embolization (PVE) has been documented as an essential strategy for patient with small future liver remnant, to minimize postoperative morbidity and mortality. The majority of hepatectomy requiring preoperative PVE is approached using conventional operation because of the anticipated complexity of the case. Laparoscopic liver resection (LLR) has been gradually increased and similar outcomes have been reported when compared to open hepatectomy. However, it is very difficult to find the reports about LLR after PVE. Hence, we will present our experiences and outcomes for LLR after PVE in hepatocellular carcinoma (HCC) patients with significant technical tips. Methods: We performed laparoscopic right hepatectomy after PVE in 8 HCC patients from 2016 to 2020. The operation was performed within 3 weeks after PVE. We confirmed the atrophy of resected liver and compensatory hypertrophy of future liver remnant using preoperative computed tomography scan. During surgery, individual inflow control was easier because right portal vein had been already occluded. Results: There was no blood transfusion and open conversion. There was no statistical difference in operation time, intraoperative complications and postoperative morbidity including hospital stay, compared to open hepatectomy. Conclusions: PVE is very useful procedure even in laparoscopic right hepatectomy as in open hepatectomy. However, caution is needed when PVE is applied cirrhotic livers. Therefore, adequate candidate selection for PVE and technical refinement are needed to decrease morbidity and increase surgical outcomes. © The Korean Association of Hepato-Biliary-Pancreatic Surgery. | Han, Jaryung; Han, Young Seok | Division of Hepatobiliary Pancreas Surgery and Liver Transplantation, Department of Surgery, Kyungpook National University Hospital, Daegu, South Korea; Division of Hepatobiliary Pancreas Surgery and Liver Transplantation, Department of Surgery, Kyungpook National University Hospital, Daegu, South Korea | 57214671308; 7404096216 | gshys@knu.ac.kr; | Annals of Hepato-Biliary-Pancreatic Surgery | 2508-5778 | 25 | 0 | 2025-07-30 | 0 | English | Final | 2021 | 10.14701/ahbps.ep-47 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Learning the Resistance Coefficients of Pendulum Motion Using Balls of Various Sizes | An optical system with a photogate was developed to measure the speed of a pendulum at the lowest point of motion to obtain the damping and the resistance coefficients of the pendulum. The photogate consisted of a photoresistor, a laser, a mechanical body, and a pendulum ball. A 3D printer was used to produce the mechanical body and pendulum balls of various sizes. Furthermore, an Arduino was used to automate the measurement of the speed at the lowest point of motion and increase the precision. It was found that the resistance coefficient was found to be proportional to the size of the balls, which is regardless of ball mass, consistent with the drag equation for a small Reynolds number. The developed instrument and program were applied to the experiment class, and positive results in education about air resistance was obtained. © 2021 The Korean Physical Society.

| ○ | ○ | Proceedings Paper | Lightweight Collaboration of Detecting and Tracking Algorithm in Low-Power Embedded Systems for Forward Collision Warning | The cause of the majority of vehicle accidents is a safety issue due to the driver's inattention, such as drowsy driving. A forward collision warning system (FCWS) can significantly reduce the number and severity of accidents by detecting the risk of collision with vehicles in front and providing an advanced warning signal to the driver. This paper describes a low power embedded system based FCWS for highway safety. The algorithm described in this paper computes time to collision (TTC) through detection, tracking, distance calculation for the vehicle ahead and current vehicle speed information with a single camera. Additionally, in order to operate in real time even in a low-performance embedded system, an optimization technique in the program with high and low levels will be introduced. The system has been tested through the driving video of the vehicle in the embedded system. As a result of using the optimization technique, the execution time was about 170 times faster than that when using the previous non-optimized process. | Hong, Sunghoon; Park, Daejin | CARNAVICOM, Incheon, South Korea; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | 59837019500; 55463943600 | boltanut@knu.ac.kr; | 12TH INTERNATIONAL CONFERENCE ON UBIQUITOUS AND FUTURE NETWORKS (ICUFN 2021) | 2165-8528 | 2165-8536 | 1.21 | 2025-07-30 | 4 | 6 | Forward collision warning system; object detection; low-power vision processing; hardware-software acceleration | Forward collision warning system; hardware-software acceleration; low-power vision processing; object detection | Embedded systems; Highway accidents; Highway engineering; Object detection; Object recognition; Tracking (position); Embedded-system; Forward collision warning system; Hardware-software acceleration; Hardware/software; Low Power; Low power embedded systems; Low-power vision processing; Optimization techniques; Software acceleration; Vision processing; Vehicles | English | 2021 | 2021 | 10.1109/icufn49451.2021.9528771 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | Book chapter | Lignins and their close derivatives produced by biorefinery processes for the treatment of human diseases | Lignin is a biopolymer by-product of cellulosic waste in the paper and renewable fuel industries and can be a cheap raw material for producing high-value-added materials. These value-added products can be used in various industries, such as agriculture, food materials, fine chemicals, animal husbandry, and cosmetics. Recently, various properties of lignin and its derivatives have been explored to develop drugs for the treatment of human diseases, including microbial and viral infection, oxidative stress, metabolic disorders, and cancers. For this regard, advanced techniques are introduced to degrade lignin properly into monomers to express high selectivity for securing human diseases by the composition of the monomers. In this review, we will introduce new applications of lignin and its derivatives in pharmaceutics as a result of its prominent biological activities by selectively cleaving or modifying the lignin polymer. © 2021 Elsevier B.V.

| ○ | ○ | Review | Lipocalin-2 in Diabetic Complications of the Nervous System: Physiology, Pathology, and Beyond | Lipocalin-2 (LCN2) is a 25 kDa secreted protein that belongs to the family of lipocalins, a group of transporters of small hydrophobic molecules such as iron, fatty acids, steroids, and lipopolysaccharide in circulation. LCN2 was previously found to be involved in iron delivery, pointing toward a potential role for LCN2 in immunity. This idea was further validated when LCN2 was found to limit bacterial growth during infections in mice by sequestering iron-laden siderophores. Recently, LCN2 was also identified as a critical regulator of energy metabolism, glucose and lipid homeostasis, and insulin function. Furthermore, studies using Lcn2 knockout mice suggest an important role for LCN2 in several biobehavioral responses, including cognition, emotion, anxiety, and feeding behavior. Owing to its expression and influence on multiple metabolic and neurological functions, there has emerged a great deal of interest in the study of relationships between LCN2 and neurometabolic complications. Thorough investigation has demonstrated that LCN2 is involved in several neurodegenerative diseases, while more recent studies have shown that LCN2 is also instrumental for the progression of diabetic complications like encephalopathy and peripheral neuropathy. Preliminary findings have shown that LCN2 is also a promising drug target and diagnostic marker for the treatment of neuropathic complications from diabetes. In particular, future translational research related to LCN2, such as the development of small-molecule inhibitors or neutralizing antibodies against LCN2, appears essential for exploring its potential as a therapeutic target. | Bhusal, Anup; Lee, Won-Ha; Suk, Kyoungho | Kyungpook Natl Univ, Sch Med, Dept Pharmacol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu, South Korea; Kyungpook Natl Univ, Sch Life Sci, BK21 FOUR KNU Creat BioRes Grp, Daegu, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Daegu, South Korea | 57200274141; 57205609794; 7005114595 | ksuk@knu.ac.kr; | FRONTIERS IN PHYSIOLOGY | 1664-042X | 12 | 0.65 | 2025-07-30 | 24 | 22 | lipocalin-2; immunity; energy metabolism; diabetes; neuroinflammation; diabetic complications; nervous system | diabetes; diabetic complications; energy metabolism; immunity; lipocalin-2; nervous system; neuroinflammation | neutrophil gelatinase associated lipocalin; anxiety; bacterial growth; brain disease; cognition; depression; diabetic complication; diabetic neuropathy; emotion; energy metabolism; feeding behavior; food intake; glucose homeostasis; human; knockout mouse; lipid homeostasis; neurologic disease; nonhuman; pathology; physiological stress; Review; validation process | English | 2021 | 2021-02-05 | 10.3389/fphys.2021.638112 | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Liquid Chromatography-Tandem Mass Spectrometric Analysis of Nannozinone A and Its Application to Pharmacokinetic Study in Mice | We aimed to develop and validate a sensitive analytical method of nannozinone A, active metabolite of Nannochelins A extracted from the Myxobacterium Nannocytis pusilla, in mouse plasma using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Mouse plasma samples containing nannozinone A and C-13-caffeine (internal standard) were extracted using a liquid-liquid extraction (LLE) method with methyl tert-butyl ether. Standard calibration curves were linear in the concentration range of 1 - 1000 ng/mL (r(2) > 0.998) with the inter- and intra-day accuracy and precision results less than 15%. LLE method gave results in the high and reproducible extraction recovery in the range of 78.00-81.08% with limited matrix effect in the range of 70.56-96.49%. The pharmacokinetics of nannozinone A after intravenous injection (5 mg/kg) and oral administration (30 mg/kg) of nannozinone A were investigated using the validated LC-MS/MS analysis of nannozinone A. The absolute oral bioavailability of nannozinone A was 8.82%. Plasma concentration of nannozinone A after the intravenous injection sharply decreased for 4 h but plasma concentration of orally administered nannozinone A showed fast distribution and slow elimination for 24 h. In conclusion, we successfully applied this newly developed sensitive LC-MS/MS analytical method of nannozinone A to the pharmacokinetic evaluation of this compound. This method can be useful for further studies on the pharmacokinetic optimization and evaluating the druggability of nannozinone A including its efficacy and toxicity. | Lee, Chul Haeng; Kim, Soobin; Lee, Jaehyeok; Jeon, Ji-Hyeon; Song, Im-Sook; Han, Young Taek; Choi, Min-Koo | Dankook Univ, Coll Pharm, Cheonan 31116, South Korea; Kyungpook Natl Univ, Coll Pharm, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea | 57219051827; 57223912938; 57219980183; 57204685946; 7201564500; 36097949800; 8695781400 | hany@dankook.ac.kr;minkoochoi@dankook.ac.kr; | MASS SPECTROMETRY LETTERS | MASS SPECTROM LETT | 2233-4203 | 2093-8950 | 12 | 1 | ESCI | SPECTROSCOPY | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | Nannozinone A; LC-MS/MS analysis; pharmacokinetics | LC-MS/MS analysis; Nannozinone A; Pharmacokinetics | English | 2021 | 2021-03 | 10.5478/msl.2021.12.1.000 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Liquid chromatography-tandem mass spectrometric analysis of oleracone D and its application to pharmacokinetic study in mice | We have demonstrated a sensitive analytical method of measuring oleracone D in mouse plasma using a liquid chromatography-tandem mass spectrometry (LC-MS/MS). Oleracone D and oleracone F (internal standard) in mouse plasma samples were processed using a liquid-liquid extraction method with methyl tertbutyl ether, resulting in high and reproducible extraction recovery (80.19-82.49 %). No interfering peaks around the peak elution time of oleracone D and oleracone F were observed. The standard calibration curves for oleracone D ranged from 0.5 to 100 ng/mL and were linear with r(2) of 0.992. The inter- and intra-day accuracy and precision and the stability fell within the acceptance criteria. The pharmacokinetics of oleracone D following intravenous and oral administration of oleracone D at doses of 5 mg/kg and 30 mg/kg, respectively, were investigated. When oleracone D was intravenously injected, it had first-order elimination kinetics with high clearance and volume of distribution values. The absolute oral bioavailability of this compound was calculated as 0.95 %, with multi-exponential kinetics. The low aqueous solubility and a high oral dose of oleracone D may explain the different elimination kinetics of oleracone D between intravenous and oral administration. Collectively, this newly developed sensitive LC-MS/MS method of oleracone D could be successfully utilized for investigating the pharmacokinetic properties of this compound and could be used in future studies for the lead optimization and biopharmaceutic investigation of oleracone D. | Lim, Dong Yu; Lee, Tae Yeon; Lee, Jaehyeok; Song, Im-Sook; Han, Young Taek; Choi, Min-Koo | Dankook Univ, Coll Pharm, Cheonan 31116, South Korea; Kyungpook Natl Univ, Coll Pharm, Vessel Organ Interact Res Ctr VOICE, BK21 FOUR Community Based Intelligent Novel Drug, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea | 57219057824; 57322866100; 57219980183; 7201564500; 36097949800; 8695781400 | hany@dankook.ac.kr;minkoochoi@dankook.ac.kr; | ANALYTICAL SCIENCE AND TECHNOLOGY | ANAL SCI TECHNOL | 1225-0163 | 2288-8985 | 34 | 5 | ESCI | CHEMISTRY, ANALYTICAL | 2021 | N/A | 0 | 2025-07-30 | 0 | 0 | oleracone D; LC-MS/MS; pharmacokinetics; plasma stability; protein binding | L. | LC-MS/MS; Oleracone D; Pharmacokinetics; Plasma stability; Protein binding | English | 2021 | 2021-10 | 10.5806/ast.2021.34.5.193 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Little known Curculigo brevifolia deserves a species rank: evidences from morphological, cytological and molecular data | The Curculigo brevifolia resurrected here based on morphological, cytological, and molecular phylogenetic analyses. Curculigo brevifolia morphologically resembles C. orchioides but differs in having bulbils at the tip of leaves for vegetative reproduction, leaves elongated falcately shaped, beaked fruits. Cytological parameters, karyotype formula, total haploid genome length (THL), values of CVCL, MCA also supported the distinctness of C. brevifolia and C. orchioides. Phylogenetic analysis based on cpDNA data resulted in the recognition of three clades and strongly supported the revised systematics of Hypoxidaceae. The resurrected species nests within the Curculigo clade of Hypoxidaceae and display a close phylogenetic affinity with newly added Curculigo species and C. orchioides.

| ○ | Article | Locomotion control of a humanoid robot using a biped walking pattern based on physical interaction | This paper describes a biped walking pattern for physical interaction between a human and humanoid robot. The study of the physical interaction between robots and humans is an important research field when considering a future society where humans and robots must coexist. In this paper, to move the humanoid robot in the direction intended by the human, the previous method of generating a walking pattern is extended to a method of generating a walking pattern suitable for physical human-robot interaction. When the human applies disturbance to the robot, the robot naturally move in the direction of applied disturbance to recover balance. The applied disturbance is measured by the capture point. To stabilize the perturbed capture point, the desired Zero Moment Point (ZMP) is calculated by using the capture point control. This desired ZMP is tracked by the walking pattern generator. The walking pattern generator automatically calculate the center of mass trajectory, which satisfies the ZMP constraint, by model predictive control. The proposed method was applied to the humanoid robot DRC-HUBO+ and verified that it can be used for physical human-robot interaction. © ICROS 2021. | Joe, Hyun-Min | Department of Robot & Smart System Engineering, South Korea, Department of Artificial Intelligence, Kyungpook National University, South Korea | 57188687051 | hmjoe@knu.ac.kr; | Journal of Institute of Control, Robotics and Systems | 1976-5622 | 27 | 9 | 0.39 | 2025-07-30 | 5 | Biped walking pattern; Capture point; Humanoid robot; Model predictive control; Zero moment point | Agricultural robots; Anthropomorphic robots; Man machine systems; Model predictive control; Applied disturbances; Biped walking pattern; Locomotion control; Physical human-robot interactions; Physical interactions; Walking pattern; Walking pattern generator; Zero moment point; Human robot interaction | Korean | Final | 2021 | 10.5302/j.icros.2021.21.0075 | 바로가기 | 바로가기 | |||||||||||||||
| ○ | Proceedings Paper | Lognroll: Discovering Accurate Log Templates by Iterative Filtering | Modern IT systems rely heavily on log analytics for critical operational tasks. Since the volume of logs produced from numerous distributed components is overwhelming, it requires us to employ automated processing. The first step of automated log processing is to convert streams of log lines into the sequence of log format IDs, called log templates. A log template serves as a base string with unfilled parts from which logs are generated during runtime by substitution of contextual information. The problem of log template discovery from the volume of collected logs poses a great challenge due to the semi-structured nature of the logs and the computational overheads. Our investigation reveals that existing techniques show various limitations. We approach the log template discovery problem as search-based learning by applying the ILP (Inductive Logic Programming) framework. The algorithm core consists of narrowing down the logs into smaller sets by analyzing value compositions on selected log column positions. Our evaluation shows that it produces accurate log templates from diverse application logs with small computational costs compared to existing methods. With the quality metric we defined, we obtained about 21%-51% improvements of log template quality. | Tak, Byungchul; Han, Wook-Shin | Kyungpook Natl Univ, Daegu, South Korea; Pohang Univ Sci & Technol, Pohang, South Korea | Han, WookShin/NIU-9096-2025 | bctak@knu.ac.kr;wshan@dblab.postech.ac.kr; | PROCEEDINGS OF THE 2021 22ND INTERNATIONAL MIDDLEWARE CONFERENCE, MIDDLEWARE 2021 | 3 | Log template; Log analysis; Sequential covering | REGULAR EXPRESSIONS | English | 2021 | 2021 | 10.1145/3464298.3493400 | 바로가기 | 바로가기 | ||||||||||||||||||||
| ○ | ○ | Article | Long-term stability in γ-CsPbI3 perovskite via an ultraviolet-curable polymer network | Black-colored (alpha, gamma-phase) CsPbI3 perovskites have a small bandgap and excellent absorption properties in the visible light regime, making them attractive for solar cells. However, their long-term stability in ambient conditions is limited. Here, we demonstrate a strategy to improve structural and electrical long-term stability in gamma-CsPbI3 by the use of an ultraviolet-curable polyethylene glycol dimethacrylate (PEGDMA) polymer network. Oxygen lone pair electrons from the PEGDMA are found to capture Cs+ and Pb2+ cations, improving crystal growth of gamma-CsPbI3 around PEGDMA. In addition, the PEGDMA polymer network strongly contributes to maintaining the black phase of gamma-CsPbI3 for more than 35 days in air, and an optimized perovskite film retained similar to 90% of its initial electrical properties under red, green, and blue light irradiation. | Cho, Nam-Kwang; Na, Hyun-Jae; Yoo, Jeeyoung; Kim, Youn Sang | Seoul Natl Univ, Grad Sch Convergence Sci & Technol, Program Nano Sci & Technol, Seoul, South Korea; Samsung Display Co Ltd, Yongin, Gyeonggi Do, South Korea; Kyungpook Natl Univ, Sch Energy Engn, Daegu, South Korea; Seoul Natl Univ, Sch Chem & Biol Engn, Seoul, South Korea; Seoul Natl Univ, Inst Chem Proc, Seoul, South Korea | Kim, SoW/ABB-7917-2021; Yoo, Jeeyoung/AAH-1359-2019 | 55831609600; 57211211648; 56046607500; 8938854200 | younskim@snu.ac.kr; | COMMUNICATIONS MATERIALS | COMMUN MATER | 2662-4443 | 2 | 1 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2021 | N/A | 1.31 | 2025-07-30 | 23 | 24 | ALPHA-CSPBI3; STABILIZATION; PHASE | Energy gap; Light; Perovskite; Polymers; Absorption property; Ambient conditions; Dimethacrylates; Lone pair electrons; Long term stability; Perovskite films; Polymer networks; Ultraviolet curable; Lead compounds | English | 2021 | 2021-03-19 | 10.1038/s43246-021-00134-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
