| ○ | Article | Improvement of Surface-enhanced Raman Spectroscopy Response Characteristics of Nanoporous Ag Metal Thin Film with Surface Texture Structures | In this study, we developed a method of improving the surface-enhanced Raman spectroscopy (SERS) response characteristics by depositing a nanoporous Ag metal thin film through cluster source sputtering after forming a pyramidal texture structure on the Si substrate surface. A reactive ion etching (RIE) system with a metal mesh inside the system was used to form a pyramidal texture structure on the Si surface without following a complicated photolithography process, unlike in case of the conventional RIE system. The size of the texture structure increased with the RIE process time. However, after a process time of 60 min, the size of the structure did not increase but tended to saturate. When the RF power increased from 200 to 250 W, the size of the pyramidal texture structure increased from 0.45 to 0.8 μm. The SERS response characteristics were measured by depositing approximately 1.5 μm of nanoporous Ag metal thin film through cluster sputtering on the formed texture structure by varying the RIE process conditions. The Raman signal strength of the nanoporous Ag metal thin film deposited on the Si substrate with the texture structure was higher than that deposited on the general silicon substrate by up to 19%. The Raman response characteristics were influenced by the pyramid size and the number of pyramids per unit area but appeared to be influenced more by the number of pyramids per unit area. Therefore, further studies are required in this regard. © 2020, Korean Sensors Society.

| ○ | Article | Improvement of the carrier transport property and interfacial behavior in InGaAs quantum well Metal-Oxide-Semiconductor Field-Effect-Transistors with sulfur passivation | In this study, we investigated the effect of a sulfur passivation (S-passivation) process step on the electrical properties of surface-channel In0.7Ga0.3As quantum-well (QW) metal-oxide-semiconductor field-effect transistors (MOSFETs) with S/D regrowth contacts. We fabricated long-channel In0.7Ga0.3As QW MOSFETs with and without (NH4)2S treatment and then deposited 1/4 nm of Al2O3/HfO2 through atomic layer deposition. The devices with S-passivation exhibited lower values of subthreshold swing (74 mV/decade) and drain-induced barrier lowering (19 mV/V) than the devices without S-passivation. A conductance method was applied, and a low value of interface trap density Dit (2.83×1012 cm-2eV-1) was obtained for the devices with S-passivation. Based on these results, interface traps between InGaAs and high-κ are other defect sources that need to be considered in future studies to improve III-V microsensor sensing platforms. © 2020, Korean Sensors Society.

| ○ | Book chapter | In vivo tracking of tumor-derived bioluminescent extracellular vesicles in mice | Extracellular vesicles (EVs) are nano-membrane vesicles containing exosomes and microvesicles, and are released by almost all types of cells. They can carry lipids, proteins, mRNAs, and miRNAs to enable intercellular communication between cells either locally or distantly without direct cell-to-cell contact. Cancer-derived EVs are known to facilitate tumor progression and metastasis by preparing premetastatic niches. Here, we define a strategy to label cancer derived EVs with Renilla luciferase for noninvasive bioluminescence imaging (BLI) and monitoring of intravenously administered EVs in vivo. © Springer Science+Business Media, LLC, part of Springer Nature 2020. | Gangadaran, Prakash; Ahn, Byeong-Cheol | Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Nuclear Medicine, Kyungpook National University Hospital, Daegu, South Korea; Department of Nuclear Medicine, School of Medicine, Kyungpook National University, Daegu, South Korea, Department of Nuclear Medicine, Kyungpook National University Hospital, Daegu, South Korea | 54393130400; 7202791511 | abc2000@knu.ac.kr; | Methods in Molecular Biology | 1064-3745 | 2081 | 0.8 | 2025-06-25 | 4 | Bioluminescence; Cancer cells; Coelenterazine; Extracellular vesicles; Renilla luciferase | Animals; Cell Line, Tumor; Cell Tracking; Disease Models, Animal; Extracellular Vesicles; Gene Expression; Genes, Reporter; Heterografts; Luminescent Measurements; Mice; Neoplasms; Renilla luciferin 2 monooxygenase; animal cell; bioluminescence; cell tracking; controlled study; exosome; human; human cell; in vivo study; internal ribosome entry site; malignant neoplasm; mouse; non invasive procedure; nonhuman; promoter region; ultracentrifugation; animal; diagnostic imaging; disease model; exosome; gene expression; luminescence; metabolism; neoplasm; pathology; procedures; reporter gene; tumor cell line; xenograft | English | Final | 2020 | 10.1007/978-1-4939-9940-8_14 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | In-vivo quantitative depth measurement of the human gingival sulcus based on interferometry system with detection algorithm | Optical coherence tomography (OCT) has magnetized substantial notice in biomedical optical imaging since it can reveal the inner structures. Gingival is a soft tissue that surrounds a tooth. In dentistry, the depth of the gingival sulcus reveals clinical diagnostic criteria for periodontal tissue status. We propose an algorithm for measuring the gingival sulcus in the OCT 2D cross-sectional images and verified the algorithm using OCT systems with three different wavelength bands. Periodontal tissues of six healthy individuals, among them maxillary and mandibular incisors and posteriors, were taken. We have obtained a clear comparison of quantitative and qualitative measurements, and to evaluate gingival sulcus non-destructively. Additionally, commercial Sobel and Canny operators primarily used, were compared with the proposed algorithm to confirm reducing sensitivity to noise and speckle in OCT images. © 2020 by the authors. | Cho, Hoseong; Lee, Jaeyul; Song, Jaewon; Jeon, Mansik; Kim, Jeehyun | School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, South Korea; School of Electronics Engineering, College of IT Engineering, Kyungpook National University, Daegu, South Korea | 57209416599; 57188689420; 7404787965; 24171094000; 7601373350 | mansikjeon@gmail.com; | International Journal of Mechanical Engineering and Robotics Research | 2278-0149 | 9 | 5 | 0.07 | 2025-06-25 | 1 | Biomedical optical imaging; Detection algorithms; Optical coherence tomography | English | Final | 2020 | 10.18178/ijmerr.9.5.771-774 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Incidental finding of squamous cell carcinoma accompanying a fungal ball in the maxillary sinus | Malignant tumors rarely occur in the paranasal sinuses. Paranasal tumors, when they occur, exhibit atypical symptoms, such as nasal obstruction, rhinorrhea, facial pain, and nasal bleeding. Because of nonspecific symptoms commonly observed in the sinusitis and their infrequent occurrence, malignant tumors of the paranasal sinuses are generally diagnosed late. If there is bone destruction or invasion of the surrounding tissues in the imaging studies, malignant tumors could be suspected; however, without such findings, it is difficult to predict the existence of cancer. It is more difficult to suspect malignant tumors when they coexist with sinus diseases. In addition, since the concomitant presence of fungal balls and cancer is extremely rare, it is difficult to suspect the presence of cancer when treating fungal balls. We report a case of a fungal ball accompanied by squamous cell carcinoma without any sign of malignancy, such as bone destruction, which has not been reported in the English literature to date.

| ○ | ○ | Article | Incidental Serous Tubal Intraepithelial Carcinoma that Developed into Primary Peritoneal Serous Carcinoma in a Patient without BRCA Mutation | Objective: Unusual clinical course Background: Serous tubal intraepithelial carcinoma (STIC) is proposed as the precursor of ovarian, tubal, and peritoneal high-grade serous carcinoma, but the clinical significance remains unclear, especially in the normal population. We report a rare case of STIC in a patient undergoing non-prophylactic surgery who developed PPSC without a strong family history or BRCA mutations. Case Report: A 62-year-old woman presented with an abnormal pap smear (ASC-H). She underwent vaginal wall biopsy, endocervical curettage, and HPV testing, which revealed vaginal wall intraepithelial neoplasia 3 and cervical intraepithelial neoplasia 3, HPV 68 positive. Laparoscopic total hysterectomy, including an upper vagina and bilateral salpingo-oophorectomy, was performed. Postoperative histopathologic examination revealed carcinoma in situ of the cervix, and, incidentally, a serous tubal intraepithelial carcinoma (STIC) in situ of both fallopian tubes. During follow-up, the patient was diagnosed with primary peritoneal serous carcinoma (PPSC), 22 months after the initial operation. BRCA mutations were not detected. The findings in our case, coupled with current evidence, suggest the distal fallopian tube as the source of PPSC. Conclusions: After an incidental diagnosis of STIC, we recommend surveillance for BRCA mutations. Standard management remains unclear, but further surgical evaluation and/or chemotherapy should be considered in patients with isolated STIC. | Chong, Gun Oh; Park, Ji Young; Lee, Hyun Jung | Kyungpook Natl Univ, Sch Med, Dept Obstet & Gynecol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu, South Korea | 23099068000; 57210160197; 57202930844 | obgy1019@hanmail.net; | AMERICAN JOURNAL OF CASE REPORTS | AM J CASE REP | 1941-5923 | 21 | ESCI | MEDICINE, GENERAL & INTERNAL | 2020 | N/A | 0 | 2025-06-25 | 1 | 1 | Adenocarcinoma; Carcinoma in Situ; Genes, BRCA1; Peritoneum | REDUCING SALPINGO-OOPHORECTOMY; PATHOLOGICAL FINDINGS; RISK; WOMEN; DIAGNOSIS | Adenocarcinoma; Carcinoma in Situ; Genes, BRCA1; Peritoneum | Antineoplastic Agents; Carcinoma in Situ; Combined Modality Therapy; Fallopian Tube Neoplasms; Female; Humans; Hysterectomy; Incidental Findings; Middle Aged; Peritoneal Neoplasms; Salpingo-oophorectomy; antineoplastic agent; adult; Article; BRCA gene; cancer incidence; case report; clinical article; curettage; disease course; endocervical curettage; Fallopian tube; female; follow up; gene mutation; human; human tissue; hysterectomy; middle aged; oncogene; ovariectomy; ovary carcinoma; Papanicolaou test; papillomavirus infection; postoperative period; primary peritoneal serous carcinoma; uterine cervix biopsy; uterine cervix carcinoma in situ; vaginal intraepithelial neoplasia; carcinoma in situ; incidental finding; multimodality cancer therapy; peritoneum tumor; salpingooophorectomy; uterine tube tumor | English | 2020 | 2020-02-08 | 10.12659/ajcr.921146 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Indirect pathological indicators for cardiac sarcoidosis on endomyocardial biopsy | Background: The definitive pathologic diagnosis of cardiac sarcoidosis requires observation of a granuloma in the myocardial tissue. It is common, however, to receive a "negative" report for a clinically probable case. We would like to advise pathologists and clinicians on how to interpret "negative" biopsies. Methods: Our study samples were 27 endomyocardial biopsies from 25 patients, three cardiac transplantation and an autopsied heart with suspected cardiac sarcoidosis. Pathologic, radiologic, and clinical features were compared. Results: The presence of micro-granulomas or increased histiocytic infiltration was always (6/6 or 100%) associated with fatty infiltration and confluent fibrosis, and they showed radiological features of sarcoidosis. Three of five cases (60%) with fatty change and confluent fibrosis were probable for cardiac sarcoidosis on radiology. When either confluent fibrosis or fatty change was present, one-third (3/9) were radiologically probable for cardiac sarcoidosis. We interpreted cases with micro-granuloma as positive for cardiac sarcoidosis (five of 25, 20%). Cases with both confluent fibrosis and fatty change were interpreted as probable for cardiac sarcoidosis (seven of 25, 28%). Another 13 cases, including eight cases with either confluent fibrosis or fatty change, were interpreted as low probability based on endomyocardial biopsy. Conclusions: The presence of micro-granuloma could be an evidence for positive diagnosis of cardiac sarcoidosis. Presence of both confluent fibrosis and fatty change is necessary for probable cardiac sarcoidosis in the absence of granuloma. Either of confluent fibrosis or fatty change may be an indirect pathological evidence but they are interpreted as nonspecific findings. | Cha, Myung-Jin; Seo, Jeong-Wook; Oh, Seil; Park, Eun-Ah; Lee, Sang-Han; Kim, Moon Young; Park, Jae-Young | Seoul Natl Univ Hosp, Dept Internal Med, Div Cardiol, Seoul, South Korea; Seoul Natl Univ, Dept Pathol, Coll Med, 103 Daehak Ro, Seoul 03080, South Korea; Seoul Natl Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Seoul Natl Univ, Interdisciplinary Program Bioengn, Coll Med, Seoul, South Korea; Seoul Natl Univ Hosp, Cardiovasc Ctr, Cardiol Div, Seoul, South Korea; Seoul Natl Univ Hosp, Cardiac Electrophysiol Lab, Seoul, South Korea; Seoul Natl Univ Hosp, Dept Radiol, Div Cardiovasc Imaging, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Forens Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Pathol, Daegu, South Korea; Seoul Natl Univ, Dept Radiol, Seoul Metropolitan Govt, Boramae Med Ctr, Seoul, South Korea; Sejong Hosp, Dept Pathol, Bucheon, South Korea | Oh, Seil/J-5539-2012; Park, Eun-Ah/ABE-6898-2021; Park, Jae/AAQ-8991-2021 | 52263100500; 56335994300; 8552086700; 7402224708; 57192515418; 57215096096; 57219285680 | jwseo@snu.ac.kr; | JOURNAL OF PATHOLOGY AND TRANSLATIONAL MEDICINE | J PATHOL TRANSL MED | 2383-7837 | 2383-7845 | 54 | 5 | ESCI | PATHOLOGY | 2020 | N/A | 0.72 | 2025-06-25 | 10 | 10 | Myocarditis; Arrhythmogenic right ventricular dysplasia; Tachycardia; ventricular; Sarcoidosis; Cardiac muscle | MAGNETIC-RESONANCE; DIAGNOSIS; INVOLVEMENT; THERAPY | Arrhythmogenic right ventricular dysplasia; Cardiac muscle; Myocarditis; Sarcoidosis; Tachycardia; Ventricular | adipose tissue; adult; aged; Article; autopsy; cardiac sarcoidosis; cell infiltration; clinical article; clinical feature; female; granuloma; heart muscle biopsy; heart transplantation; histiocyte; histopathology; human; human tissue; male; nuclear magnetic resonance imaging; radiocardiography | English | 2020 | 2020-09 | 10.4132/jptm.2020.06.10 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Individualized episteme for multi-agent situations in virtual world | Virtual world-based education systems pursue to provide realistic pedagogical experiences in realistic situations. The diversity and realism of situations simulated in the virtual world determines the quality of pedagogical experience in immersed learning. A situation grows more complicated as it involves more agents, who belong to the same multi-agent event or many independent events. Unlike most of the serious games and conventional narrative systems, we indiscriminately model those agents to be autonomous humans regardless of their roles. That is, they have their own beliefs enabling them to behave autonomously and independently from each other. This epistemic differentiation itself provides a major source of additional situation variability compared to the omniscient-view or protagonist-centered situations of those conventional narrative systems. Each agent is designed to be incessantly update their respective episteme according to ever-changing background-world conditions to adapt their behavior proactively and reactively. Such episteme cannot be perfect due to incomplete information and partial observation, leading to misconception and epistemic discrepancies, between fact and belief and inter-agent, further deepening the situation variability. With epistemic multiplicity for autonomous and independent agents our simulation method affords the highest diversity and fidelity of pedagogical situations involving multiple agents. We developed a dynamic event-coupling scheme based on schematic functions other than the conventional pre-authored planning. This scheme can not only maximize the situation variability but drastically alleviate the authoring cost along with a real-time animation method compared to monolithically-authored conventional simulation systems. © International Research Publication House. http://www.irphouse.com | Park, Jong-Hee; Choi, Jun-Seong | School of Electronics Engineering, Kyungpook National University, South Korea; School of Electronics Engineering, Kyungpook National University, South Korea | 55717172900; 57213021325 | International Journal of Engineering Research and Technology | 0974-3154 | 13 | 8 | 0 | 2025-06-25 | 0 | Immersive pedagogical experience; Individualized episteme; Multi-agent situation; Virtual world simulation | English | Final | 2020 | 10.37624/ijert/13.8.2020.2090-2095 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | ○ | Proceedings Paper | Indoor Positioning Algorithm Based on Channel State Information using Bootstrap Filter | The traditional indoor positioning method based on the received signal strength indicator has low positioning accuracy and poor stability. To improve the positioning accuracy of the indoor environment, an indoor positioning method based on Bootstrap filtering CSI ranging model is proposed. Firstly, the least square method is used to fit the ranging model based on effective CSI value. Secondly, Bootstrap Filter is used to smoothing the ranging error of the effective CSI measurement value, and decrease the influence of the process noise. Finally, using the triangulation method to estimate the coordinates of the target position. The positioning method is verified by experiments in a representative indoor environment and compared with two existing classical positioning methods in the same indoor environment. Experiments show that, compared with the existing positioning methods, the method proposed in this paper effectively reduces the ranging error and improves the positioning accuracy. | Wang, Jingjing; Park, Joon Goo | Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | Wang, Jingjing/GLT-7562-2022 | 57202161515; 24329712800 | wjj0219@naver.com;jgpark@knu.ac.kr; | PROCEEDINGS OF THE 33RD INTERNATIONAL TECHNICAL MEETING OF THE SATELLITE DIVISION OF THE INSTITUTE OF NAVIGATION (ION GNSS+ 2020) | 2331-5911 | 2331-5954 | 0.17 | 2025-06-25 | 0 | 1 | Indoor Positioning Algorithm; Channel state information; Received signal strength Indicator; Bootstrap Filter | Bootstrap Filter; Channel state information; Indoor Positioning Algorithm; Received signal strength Indicator | Channel state information; Indoor positioning systems; Least squares approximations; Bootstrap filtering; Indoor environment; Indoor positioning; Least square methods; Positioning accuracy; Positioning methods; Received signal strength indicators; Triangulation method; Global positioning system | English | 2020 | 2020 | 10.33012/2020.17590 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | ○ | Article | Infected Pancreatic Necrosis Mimicking Pancreatic Cancer | Although infected pancreatic necrosis can develop as a result of rare conditions involving trauma, surgery, and systemic infection with an uncommon pathogen, it usually occurs as a complication of pancreatitis. Early phase of acute pancreatitis can be either edematous interstitial pancreatitis or necrotizing pancreatitis. The late complications of pancreatitis can be divided into pancreatic pseudocyst due to edematous interstitial pancreatitis or walled-off necrosis due to necrotizing pancreatitis. During any time course of pancreatitis, bacteremia can provoke infection inside or outside the pancreas. The patients with infected pancreatic necrosis may have fever, chills, and abdominal pain as inflammatory symptoms. These specific clinical presentations can differentiate infected pancreatic necrosis from other pancreatic diseases. Herein, I report an atypical case of infected pancreatic necrosis in which abdominal pain, elevation of white blood cell, and fever were not found at the time of admission. Rather, a 10-kg weight loss (from 81 to 71 kg) over 2 months nearly led to a misdiagnosis of pancreatic cancer. The patient was finally diagnosed based on endoscopic ultrasound-guided fine-needle aspiration. This case highlights that awareness of the natural course of pancreatitis and infected pancreatic necrosis is important. In addition, endoscopic ultrasound-guided fine-needle aspiration should be recommended for the diagnosis and treatment of indeterminate pancreatic lesions in selected patients. | Heo, Jun | Kyungpook Natl Univ Hosp, Dept Internal Med, 130 Dongdeok Ro, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Daegu, South Korea | 36448170600 | hero797@hanmail.net; | CASE REPORTS IN GASTROENTEROLOGY | 1662-0631 | 14 | 2 | 0.08 | 2025-06-25 | 4 | 1 | Pancreatitis; Pancreatic cancer; Endoscopic ultrasonography | Endoscopic ultrasonography; Pancreatic cancer; Pancreatitis | alanine aminotransferase; alkaline phosphatase; C reactive protein; CA 19-9 antigen; carcinoembryonic antigen; cephalosporin; glucose; hemoglobin A1c; abdominal pain; aged; antibiotic therapy; Article; body weight loss; breathing rate; case report; chill; clinical article; computer assisted tomography; cytology; endoscopic ultrasound guided fine needle biopsy; fever; follow up; glucose blood level; hospitalization; human; human tissue; hypertension; leukocyte count; male; non insulin dependent diabetes mellitus; nuclear magnetic resonance imaging; pancreas cancer; pancreas necrosis; platelet count; priority journal; pulse rate; superior mesenteric artery; tuberculosis; urea nitrogen blood level | English | 2020 | 2020 (MAY-AUG) | 10.1159/000510161 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Review | Infectious and Non-infectious Complications of Peritoneal Dialysis in Children | Despite the many advantages of peritoneal dialysis (PD) in children with end-stage renal disease, there exist redoubtable complications of PD that should be overcome. To prevent and manage these complications, a multidisciplinary team should provide support highly tailored for each child and family, based on the standardized practice guidelines for the management of pediatric PD. In this review, we summarize the clinical manifestations and management of several complications of PD. © 2020 The Korean Society of Pediatric Nephrology. | Cho, Min Hyun | Department of Pediatrics, Kyungpook National University, School of Medicine, Daegu, South Korea | 7401727726 | chomh@knu.ac.kr; | Childhood Kidney Diseases | 2384-0242 | 24 | 2 | 0.12 | 2025-06-25 | 4 | Complication; End-stage renal disease; Peritoneal dialysis | English | Final | 2020 | 10.3339/jkspn.2020.24.2.63 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Influence of initial molar ratios on the performance of low molar ratio urea-formaldehyde resin adhesives | In this paper, the influence of initial formaldehyde/urea (F/U) molar ratios on the performance of low molar ratio (1.0) urea-formaldehyde (UF) resin adhesives has been investigated. Two initial F/U molar ratios, i.e., the first and second initial molar ratios were used for the alkaline addition reaction. Three levels of the first initial F/U molar ratios (2.0, 3.0, and 4.0) and two levels of the second initial molar ratios (2.0 and 1.7) were employed to prepare a total of six UF resins with an identical final molar ratio (1.0). The basis properties, functional groups, molecular weight, crystallinity, and thermal curing properties of the UF resins were characterized in detail. Higher levels (3.0 and 4.0) of the first initial F/U molar ratio provided the UF resins with better properties (non-volatile solids content, viscosity, gelation time, pH, and specific gravity) than those of the resins prepared with the conventional level F/U molar ratio of 2.0. Statistical analysis suggested that combining the first and second initial molar ratio of 4.0 with 1.7 would result in UF resins with greater adhesion strength and lower formaldehyde emission than those of the resins prepared with other molar ratios. The results showed that higher levels of the first initial molar ratio resulted in a more branched structure, as indicated by GPC, FTIR, DSC, XRD, and greater adhesion strength than those of the other UF resins with an identical final molar ratio of 1.0. © 2020, Korean Society of Wood Science Technology.

| ○ | Article | Influence of Oxygen Partial Pressure on Radio Frequency Magnetron Sputtered Amorphous InZnSnO Thin Film Transistors | Amorphous oxide semiconductors (AOS) have been studied extensively for the past decade as a possible alternative to polysilicon thin film transistors (TFTs). One such example is amorphous InZnSnO (IZTO), which was used in this study as an active channel layer for TFTs. A 30 nm-thick IZTO film was deposited using RF magnetron sputtering with various oxygen partial pressures, followed by annealing treatment in air at 350 degrees C. The resulting films showed good optical properties with high transparency of >85% in the visible spectrum, which is important for realizing transparent devices. The amorphous IZTO TFT device showed good performance with a field-effect mobility (mu(FE)) of 29.1 cm(2)/Vs, threshold voltage (V-T) of 0.70 V, on/off current ratio (I-on/I-off) of similar to 10(8), and subthreshold swing (SS) value of 0.12 V/dec. Oxygen incorporation during deposition of the channel layer affected the overall electrical properties of the TFTs, which is associated with the change of interface trap density. | Lestari, Annisa Dwi; Putri, Maryane; Heo, Young-Woo; Lee, Hee Young | Yeungnam Univ, Sch Mat Sci & Engn, Gyongsan 38541, South Korea; Kyungpook Natl Univ, Sch Mat Sci & Engn, Daegu 41566, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 1 | 7 | InZnSnO; Amorphous Oxide; Thin Film Transistor; Oxygen Partial Pressure | ELECTRICAL-PROPERTIES; OXIDE | English | 2020 | 2020-01 | 10.1166/jnn.2020.17222 | 바로가기 | 바로가기 | ||||||||||||||||||
| ○ | Article | Influence of perceived health, anxiety, depression, and social support on quality of life in patients with meniere disease | Purpose: This study investigated factors affecting Quality of Life (QoL) of patients with Meniere disease. Methods: A descriptive study design was used. Data were collected from March to April 2020 through an online survey of 130 participants diagnosed with probable or definite Meniere disease from a community of online-based patients. The data were analyzed using the independent t-test, Pearson's correlation coefficient, and multiple linear regression analysis. Results: Perceived health, anxiety, depression, family support, and health care provider support significantly correlated with QoL. As a result of the multiple regression analysis, family support, perceived health, anxiety, and ear fullness were identified as factors influencing QoL, and these factors accounted for 65.0% of the variance in QoL. Of these variables, family support was the factor affecting the participants' QoL the most (β=.45). Conclusion: These results indicate a need for continuous efforts and strategies to increase family support to enhance the QoL of this population. In addition, to increase perceived health (which was the second most influencing factor on the QoL of this population), improved health care provider support (which showed a positive correlation with perceived health) is also warranted. Therefore, nursing interventions aiming to increase social support should be developed and implemented. © 2020 Korean Society of Adult Nursing. | Ryu, Young Mi; Joung, Woo Joung | Department of Nursing, Baekseok University, Cheonan, South Korea; College of Nursing, Kyungpook National University, Daegu, South Korea | 56437902200; 56319847900 | godblessed@knu.ac.kr; | Korean Journal of Adult Nursing | 1225-4886 | 32 | 4 | 0 | 2025-06-25 | 0 | Anxiety; Depression; Meniere disease; Quality of life; Social support | Korean | Final | 2020 | 10.7475/kjan.2020.32.4.399 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | ○ | Article | Influence of three BALB/c substrain backgrounds on the skin tumor induction efficacy to DMBA and TPA cotreatment | Differences in responsiveness of BALB/c substrains have been investigated in various fields, including diabetes induction, corpus callosum deficiency, virus-induced demyelinating disease, aggressive behavior and osteonecrosis. However, induction efficacy of skin tumor remains untried. We therefore investigated the influence of BALB/c substrain backgrounds on the skin tumor induction efficacy in response to DMBA (7,12-Dimethylbenz[a]anthracene) and TPA (12-O-tetradecanoylphorbol-13-acetate) cotreatment. Alterations in the levels of tumor growth related factors, histopathological structure, and the expression to tumor related proteins were measured in three BALB/c substrains (BALB/cKorl, BALB/cA and BALB/cB) after exposure to DMBA (25 mu g/kg) and three different doses of TPA (2, 4 and 8 mu g/kg). The average number and induction efficacy of tumors in response to DMBA+TPA treatment were significantly greater in the BALB/cKorl substrain than in BALB/cA and BALB/cB. However, cotreatment with DMBA+TPA induced similar responses for body and organ weights of all three substrains. Few differences were detected in the serum analyzing factors, while similar responsiveness was observed for blood analyzing factors after DMBA+TPA treatment. Furthermore, the three BALB/c substrains exhibited similar patterns in their histopathological structure in DMBA+TPA-induced tumors. The expression levels of apoptotic proteins and tumor related proteins were constantly maintained in all three BALB/c substrains treated with DMBA+TPA. In addition, the responsiveness to cisplatin treatment was overall very similar in the three BALB/c substrains with DMBA+TPA-induced tumors. Taken together, these results indicate that genetic background of the three BALB/c substrains does not have a major effect on the DMBA+TPA-induced skin carcinogenesis and therapeutic responsiveness of cisplatin, except induction efficacy. | Kang, Mi Ju; Gong, Jeong Eun; Kim, Ji Eun; Choi, Hyeon Jun; Bae, Su Ji; Choi, Yun Ju; Lee, Su Jin; Seo, Min-Soo; Kim, Kil Soo; Jung, Young-Suk; Cho, Joon-Yong; Lim, Yong; Hwang, Dae Youn | Pusan Natl Univ, Coll Nat Resources & Life Sci, Dept Biomat Sci, Life & Ind Convergence Res Inst,Lab Anim Resource, Miryang, South Korea; Daegu Gyeongbuk Med Innovat Fdn, Lab Anim Ctr, Daegu, South Korea; Kyungpook Natl Univ, Coll Vet Med, Daegu, South Korea; Pusan Natl Univ, Coll Pharm, Busan, South Korea; Korea Natl Sport Univ, Exercise Biochem Lab, Seoul, South Korea; Dong Eui Univ, Dept Clin Lab Sci, Coll Nursing & Healthcare Sci, Busan, South Korea | Kim, Ji/AAU-5043-2020; Kim, Seung/N-5248-2019 | 57203929408; 57215083654; 59375066900; 57206844520; 57206855055; 55819466900; 59712346200; 35254332100; 35272034300; 56428348300; 7403535804; 35262596100; 26325632700 | dyhwang@pusan.ac.kr; | LABORATORY ANIMAL RESEARCH | 1738-6055 | 2233-7660 | 36 | 1 | 0.21 | 2025-06-25 | 4 | 5 | BALB; c; BALB; cKorl; Substrains; DMBA plus TPA; Cisplatin; Skin tumor | ICR MICE; CARCINOGENESIS; STRAINS; MUTANT; MODEL | BALB/c; BALB/cKorl; Cisplatin; DMBA+TPA; Skin tumor; Substrains | English | 2020 | 2020-09-03 | 10.1186/s42826-020-00063-z | 바로가기 | 바로가기 | 바로가기 |
