| ○ | ○ | Article | Exudative Retinal Detachment after Pembrolizumab Treatment in Metastatic Cutaneous Melanoma | Purpose: To report a case of exudative retinal detachment after using pembrolizumab in a patient with metastatic cutaneous melanoma. Case summary: A 67 -year -old woman, diagnosed with malignant melanoma of the right thumb and axillary metastasis, presented with bilateral visual disturbance 3 days after adjuvant chemotherapy with pembrolizumab. Her best corrected visual acuity was 0.2 in the right eye and 0.7 in the left, while the intraocular pressure was 14 mmHg in both eyes. Fundus examination showed serous retinal detachment and choroidal detachment in the right eye, as well as a chorioretinal folding in both eyes. Optical coherence tomography showed exudative retinal detachment and choroidal detachment in the right eye, along with choroidal folding in both eyes. The pembrolizumab was stopped immediately, and the patient began treatment with systemic and topical steroids. After 1 month, the visual acuity improved and there was no exudative retinal detachment or choroidal detachment. However, 3 weeks later, exudative retinal detachment recurred in both eyes. The patient started treatment with oral steroids and cyclosporine, which resulted in the resolution of the exudative retinal detachment after 1 month. Conclusions: Exudative retinal detachment may occur as a side effect of pembrolizumab treatment. Therefore, a differential diagnosis and appropriate treatment of ocular side effects are necessary.

| ○ | ○ | Article | One-year Clinical Outcome of Topical Bromfenac in Central Serous Chorioretinopathy | Purpose: To evaluate the efficacy of topical bromfenac in treating central serous chorioretinopathy (CSC) over a 1-year period. Methods: A retrospective analysis was conducted on 57 patients (57 eyes) with CSC followed for > 1 year. Patients were divided into two groups: those treated with bromfenac eye drops twice daily (29 eyes) and a control group (28 eyes). Best-corrected visual acuity (BCVA), central macular thickness (CMT), and subretinal fluid (SRF) height were measured and compared between the two groups as was the proportion of chronic cases. Results: Significant improvements in CMT and SRF height were noted in both groups over the follow-up period. The bromfenac group demonstrated significantly lower CMT at 6, 9, and 12 months ( p = 0.045, 0.042, and 0.023, respectively) and lower SRF height ( p = 0.037, 0.048, and 0.046, respectively) compared to the control group. The proportion of chronic cases was significantly lower in the bromfenac group (17.2%) compared to the control group (42.9%, p = 0.035). Conclusions: Topical bromfenac reduced the rate of progression to chronic CSC and showed significant anatomical improvements after 6 months, suggesting its potential as an effective treatment option.

| ○ | ○ | Article | Unilateral Internuclear Ophthalmoplegia in a 14-year-old Female | Purpose: Internuclear ophthalmoplegia (INO) is an eye movement disorder caused by a lesion of the medial longitudinal fasciculus. It typically manifests bilaterally and is commonly caused by multiple sclerosis. We report a case of pediatric unilateral INO, which is rare in the pediatric population. Case summary: A 14 -year -old female, with a history of traumatic head injury 9 days previously, presented with diplopia, nausea and vomiting for the past 5 days. Her ophthalmic examination revealed severely impaired adduction of the right eye and abduction nystagmus in the left eye. Orbital computed tomography showed no evidence of orbital wall fracture or muscle impingement. However, an magnetic resonance imaging of her brain demonstrated an infarct in the right paramedian midbrain, leading to a diagnosis of unilateral INO. Diplopia and impaired adduction of the right eye resolved completely 7 weeks after the trauma. Conclusions: Demyelinating diseases, such as multiple sclerosis, account for most of the pediatric INO cases. Although most of these cases are bilateral, this reports highlights a pediatric case of unilateral INO following head injury, which is an uncommon occurrence in this | Oh, Il Joong; Oh, Jun Ho; Chun, Bo Young | Kyungpook Natl Univ, Sch Med, Dept Ophthalmol, 130 Dongdeok Ro, Daegu 700721, South Korea; Kyungpook Natl Univ, Brain Sci & Engn Inst, Sch Med, Daegu, South Korea | 58989811700; 57216588714; 25644902100 | byjun424@hotmail.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 65 | 4 | ESCI | OPHTHALMOLOGY | 2024 | 0.1 | 97.4 | 0 | 2025-05-07 | 0 | 0 | Brain infarctions; Head injuries; Internuclear ophthalmoplegia; Medial longitudinal fasciculus; Pediatrics | INTER-NUCLEAR OPHTHALMOPLEGIA | Brain infarctions; Head injuries; Internuclear ophthalmoplegia; Medial longitudinal fasciculus; Pediatrics | English | 2024 | 2024-04 | 10.3341/jkos.2024.65.4.304 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Removal of Artifacts in EEG Signals due to Random Whole-Body Vibration and Analysis of Discomfort for Seated Passengers | Whole-body vibration-induced discomfort has long been assessed using self-reports and accelerations. In contrast to previous studies, we analyzed vibration-induced discomfort through stress analysis of electroencephalogram (EEG) signals. Head acceleration and EEG signals were measured from 22 seated participants excited to random vibration. Before stress analysis, a strong correlation between EEG and acceleration signals was observed and removed using an adaptive filter. Stress analysis was performed using alpha asymmetry and relative alpha band power in the frontal lobe. Through the stress analysis, we confirmed that whole-body vibration induces mental stress and that stress increases with increasing magnitude. The results and methodology of this study are expected to be used for ride comfort assessment alongside existing self-report and acceleration methods | Song, Byoung-Gyu; Kang, Namcheol | Kyungpook Natl Univ, Dept Mech Engn, Daegu, South Korea | nckang@knu.ac.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 48 | 1 | ESCI | ENGINEERING, MECHANICAL | 2024 | 0.2 | 97.5 | 0 | Adaptive Filter; Ride Comfort; Electroencephalogram; Movement Artifact(; Whole-body Vibration | DYNAMICS; FEATURES | English | 2024 | 2024-01 | 10.3795/ksme-a.2024.48.1.021 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | VHCF, Tribology Amp, and Impact Characteristics of Bainite and Tempered Martensite Spring Steels | : Studies have reported that the bainitic structure obtained by austempering spring steels exhibits higher strength and ductility than the Q/T-treated tempered martensite structure. However, quantitative studies on VHCF, tribology, and impact characteristics of bainitic steel required for the durability design of next-generation springs are insufficient. Therefore, in this study, fatigue characteristics of VHCF that is a new VHCF design standard with spring steel of bainite and tempered martensite structures were obtained. We quantitatively analyzed the characteristics of microstructure transformation associated with heat treatment cycles and studied and analyzed the fatigue, VHCF, tribology, and impact characteristics using the fracture mechanics method and fracture surface analysis through EBSD, SEM, and EDS. | Nahm, Seung-Hoon; Cho, In-Sik; Suh, Chang-Min; Park, No-keun | Korea Res Inst Stand & Sci, Daejeon, South Korea; Sun Moon Univ, Mat Sci & Engn, Asan, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu, South Korea; Yeungnam Univ, Sch Mat Sci & Engn, Gyongsan, South Korea | 35220422900; 36560952200; 7102970945; 54880673900 | shnahm@kriss.re.kr; | TRANSACTIONS OF THE KOREAN SOCIETY OF MECHANICAL ENGINEERS A | T KOR SOC MEC ENG A | 1226-4873 | 2288-5226 | 48 | 8 | ESCI | ENGINEERING, MECHANICAL | 2024 | 0.2 | 97.5 | 0 | 2025-05-07 | 0 | 0 | Spring Steel; Electron Back Scatter Diffraction(EBSD; Bainite; Tempered Martensite; Very High Cycle Fatigue(VHCF | FATIGUE BEHAVIOR; SI | Bainite; Electron Back Scatter Diffraction; Spring Steel; Tempered Martensite; Very High Cycle Fatigue | Bainite; Bainitic transformations; Fracture mechanics; High-cycle fatigue; Austempering; Bainitic structure; Electron back scatter diffraction; Electron backscatter diffraction; Fatigue characteristics; Impact characteristics; Martensite structures; Spring steel; Tempered martensite; Very-High-Cycle Fatigue; Martensite | Korean | 2024 | 2024-08 | 10.3795/ksme-a.2024.48.8.543 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Toll-like receptor 2-mediated ERK activation significantly upregulates interleukin-6 expression in M2-polarized macrophages | Objectives M2-polarized macrophages and interleukin (IL)-6 significantly alter the tumor microenvironment and promote the malignant behaviors of tumor cells. This study aimed to establish M2-type macrophages from THP-1 cells, which are human leukemia monocytes, and investigate the significance of toll-like receptor 2 (TLR2) signaling in IL-6 production.Methods THP-1 cells were treated with phorbol 12-myristate 13-acetate, IL-4, and IL-13 to stimulate their differentiation into M2 macrophages. Cell differentiation was confirmed by cytokine production, marker expression, and morphological alterations. Treatment with TLR agonists induced TLR stimulation in M2 macrophages. Subsequently, secretion and expression levels of IL-6 in M2 macrophages were measured using enzyme-linked immunosorbent assay, quantitative reverse transcription-polymerase chain reaction, and western blotting.Results Myeloid differentiation factor 88, tumor necrosis factor-associated factor 6, and IL-1 receptor-associated kinase-1/4 signaling pathways contributed to IL-6 production upon TLR2 activation in M2 macrophages. While both TLR2 and TLR4 activated NF-kappa B in M2 macrophages, IL-6 production was mainly dependent on TLR2, not TLR4, suggesting the involvement of major mechanisms other than NF-kappa B in IL-6 production. Notably, TLR2-stimulated extracellular signal-regulated kinase (ERK) was necessary for abundant IL-6 production, indicating that TLR2-mediated ERK signaling plays an essential role in M2 macrophages.Conclusions These results highlight the significance of TLR2 signaling in IL-6 production by M2 macrophages and provide insights into the underlying regulatory mechanisms. | Jo, Wol Soon; Kim, Sung Dae; Jeong, Soo Kyung; Oh, Su Jung; Baik, Ji Sue; Seo, Ji An; Baek, Jeong-Hwa; Lee, Chang Geun; Kang, Young-Rok; Jeong, Min Ho; Park, Moon-Taek | Dept Microbiol, Daeshingongwon-gil 32, Busan 49236, South Korea; Dong A Univ, Res Ctr, Coll Med, Dongnam Inst Radiol & Med Sci DIRAMS, Busan 46033, South Korea; Dongnam Inst Radiol & Med Sci DIRAMS, Res Ctr, Busan, South Korea; Kyungpook Natl Univ, Coll Vet Med, Dept Vet Med, Daegu 41566, South Korea | 59030149100; 55156746000; 36086263600; 54682218500; 55193419800; 59296387300; 57210597065; 17137195400; 57542731000; 57196873042; 7404490344 | mhjeong@dau.ac.kr;mtpark@dirams.re.kr; | TURKISH JOURNAL OF BIOCHEMISTRY-TURK BIYOKIMYA DERGISI | TURK J BIOCHEM | 0250-4685 | 1303-829X | 49 | 6 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY | 2024 | 0.7 | 97.6 | 0 | 2025-05-07 | 0 | 0 | TLR2; IL-6; ERK; M2 macrophage | NF-KAPPA-B; CANCER; IL-6; POLARIZATION; CYTOKINE; MAPK | ERK; IL-6; M2 macrophage; TLR2 | immunoglobulin enhancer binding protein; interleukin 1 receptor; interleukin 10; interleukin 13; interleukin 4; interleukin 6; lipopolysaccharide; marker; mitogen activated protein kinase; mitogen activated protein kinase p38; myeloid differentiation factor 88; neutralizing antibody; phorbol 13 acetate 12 myristate; protein kinase; stress activated protein kinase; toll like receptor 2; toll like receptor 4; toll like receptor agonist; transforming growth factor beta; tumor necrosis factor receptor associated factor 6; Article; cell culture; cell differentiation; chemoluminescence; cytokine production; cytokine release; electronic spreadsheet; enzyme linked immunosorbent assay; Escherichia coli; flow cytometry; gene expression; human; human cell; Listeria monocytogenes; M2 macrophage; macrophage; MAPK signaling; monocyte; mRNA expression level; polarization; polyacrylamide gel electrophoresis; protein expression; protein phosphorylation; real time polymerase chain reaction; RNA extraction; signal transduction; THP-1 cell line; tumor microenvironment; upregulation; Western blotting | English | 2024 | 2024-12-31 | 10.1515/tjb-2024-0105 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Application to Piezoelectric and Triboelectric Generators of Spongy Structured BaTiO3 Prepared by Sputtering | New piezoelectric and triboelectric materials for energy harvesting are being widely researched to reduce their processing cost and complexity and to improve their energy conversion efficiency. In this study, BaTiO3 films of various thickness were deposited on Ni foams by R.F. magnetron sputtering to study the piezoelectric and triboelectric properties of the porous spongy structure materials. Then piezoelectric nanogenerators (PENGs) were prepared with spongy structured BaTiO3 and PDMS composite. The output performance exhibited a positive dependence on the thickness of the BaTiO3 film, pushing load, and poling. The PENG output voltage and current were 4.4 V and 0.453 mu A at an applied stress of 120 N when poled with a 300 kV/cm electric field. The electrical properties of the fabricated PENG were stable even after 5,000 cycles of durability testing. The triboelectric nanogenerators (TENGs) were fabricated using spongy structured BaTiO3 and various polymer films as dielectrics and operated in a vertical contact separation mode. The maximum peak to peak voltage and current of the composite film -based triboelectric nanogenerator were 63.2 V and 6 mu A, respectively. This study offers new insights into the design and fabrication of high output nanogenerators using spongy structured materials. | Kim, Seon-A; Park, Sang-Shik | Kyungpook Natl Univ, Dept Energy Mat & Chem Engn, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju 37224, South Korea; Kyungpook Natl Univ, Sangju, South Korea | 58983737100; 7501833211 | parkss@knu.ac.kr; | KOREAN JOURNAL OF MATERIALS RESEARCH | KOR J MATER RES | 1225-0562 | 2287-7258 | 34 | 1 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 0.3 | 98.2 | 0 | 2025-04-16 | 0 | 0 | nanogenerator; piezoelectric; triboelectric; BaTiO3; sponge structure | NANOGENERATOR; PERFORMANCE | BaTiO<sub>3</sub>; Key words nanogenerator; piezoelectric; sponge structure; triboelectric | Barium titanate; Durability; Energy conversion efficiency; Foams; Piezoelectricity; Polymer films; Triboelectricity; Key word nanogenerator; Key words; Nanogenerators; Piezoelectric; Piezoelectric generators; Piezoelectric nanogenerator; Processing complexity; Sponge structures; Tribo-electric generator; Triboelectric; Nanogenerators | English | 2024 | 2024-01 | 10.3740/mrsk.2024.34.1.34 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Characteristics of Bio-Piezoelectric Generator Using Edible Collagen Powder | Because collagen is inherently piezoelectric, research is being actively conducted to utilize it to harvest energy. In this study, a collagen solution was prepared using edible low-molecular-weight peptide collagen powder, and collagen films were fabricated using a dip coating method. The collagen films prepared by dip coating showed a smooth surface without defects such as pinholes or cracks. Dehydrothermal treatment of the collagen films was performed to induce a stable molecular structure through cross-linking. The collagen film subjected to dehydrothermal treatment at 110 degrees C for 24 h showed a thickness reduction rate of 19 %. Analysis of the collagen films showed that the crystallinity of the collagen film improved by about 7.9 % after dehydrothermal treatment. A collagen film-based piezoelectric nanogenerator showed output characteristics of approximately 13.7 V and 1.4 mu A in a pressure test of 120 N. The generator showed a maximum power density of about 2.91 mW/m(2) and an output voltage of about 8 similar to 19 V during various human body movements such as finger tapping. The collagen film-based piezoelectric generator showed improved output performance with improved crystallinity and piezoelectricity after dehydrothermal treatment. | Son, Ha-Young; Park, Sang-Shik | Kyungpook Natl Univ, Dept Energy Mat & Chem Engn, Sangju 37224, South Korea; Kyungpook Natl Univ, Dept Adv Sci & Technol Convergence, Sangju 37224, South Korea; Kyungpook Natl Univ, Adv Battery Res Inst, Sangju 37224, South Korea | 58783540000; 7501833211 | parkss@knu.ac.kr; | KOREAN JOURNAL OF MATERIALS RESEARCH | KOR J MATER RES | 1225-0562 | 2287-7258 | 34 | 4 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 0.3 | 98.2 | 0 | 2025-04-16 | 0 | 0 | piezoelectric nanogenerator; collagen film; dehydrothermal treatment; biopiezoelectric material | CROSS-LINKING; THIN-FILMS; FABRICATION; NANOGENERATOR; DENATURATION; REGENERATION; BONE; FISH | biopiezoelectric material; collagen film; dehydrothermal treatment; piezoelectric nanogenerator | Coatings; Crystallinity; Crystallography; Film preparation; Nanogenerators; Piezoelectricity; Biopiezoelectric material; Collagen films; Cristallinity; Dehydrothermal treatment; Energy; Low-molecular-weight peptides; Piezoelectric; Piezoelectric generators; Piezoelectric nanogenerator; Powder films; Collagen | Korean | 2024 | 2024-04 | 10.3740/mrsk.2024.34.4.215 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Silicon-Organic Hybrid Solar Cell Using Ag Nanowire/PEDOT:PSS Layer | Among various organic materials suitable for silicon-based inorganic-organic hybrid solar cells, poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) has been extensively studied due to its high optical transmittance, high work function, and low bandgap characteristics. The electro-optical properties of PEDOT:PSS have a significant impact on the power conversion efficiency of silicon-organic hybrid solar cells. To enhance the photovoltaic properties of the silicon-organic hybrid solar cells, we developed a method to improve the properties of the PEDOT:PSS film using Ag nanowires (NW) instead of conventional solvent addition methods. The influence of the Ag NW on the electro-optical property of the PEDOT:PSS film and the photovoltaic performance of the silicon-organic hybrid solar cells were investigated. The addition of Ag NW further improved the sheet resistance of the PEDOT:PSS film, enhancing the performance of the silicon-organic hybrid solar cells. The present work using the low sheet resistance PEDOT:PSS layer paves the way to develop simple yet more efficient silicon- organic hybrid solar cells. | Kim, Kyudong; Jo, Sungjin | Kyungpook Natl Univ, Sch Energy Engn, Daegu 41566, South Korea | 59355122000; 7101724027 | sungjin@knu.ac.kr; | KOREAN JOURNAL OF MATERIALS RESEARCH | KOR J MATER RES | 1225-0562 | 2287-7258 | 34 | 8 | ESCI | MATERIALS SCIENCE, MULTIDISCIPLINARY | 2024 | 0.3 | 98.2 | 0 | 2025-05-07 | 0 | 0 | solar cell; silicon; silver nanowire; hybrid; organic | ELECTRICAL-CONDUCTIVITY | hybrid; organic; silicon; silver nanowire; solar cell | Conducting polymers; Hard facing; Optical depth; Organic solar cells; Organic-inorganic materials; Transparent conducting oxides; Ag nanowires; Electrooptical properties; Ethylenedioxythiophenes; Hybrid; Hybrid solar cells; Organic hybrids; Organic materials; Organics; Poly(styrene sulfonate); Silver nanowires; Silver nanowires | English | 2024 | 2024-08 | 10.3740/mrsk.2024.34.8.395 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of Audio-visual and Contextual Conditions on Auditory Word Recognition in Patients with Normal Pressure Hydrocephalus | Objectives: In this study, we compared performance on the auditory word recognition tasks between patients with normal pressure hydrocephalus (NPH) and healthy elderly adults (HE) under different visual, auditory, and contextual conditions to determine how these variables affect auditory comprehension with cognitive decline. Methods: We conducted a standardized comprehension assessment, Paradise Korean Western Aphasia Battery Revised (PK-WAB-R) and the auditory word recognition tasks on 30 patients with NPH and 30 HE. The auditory word recognition task was divided into noisy and quiet conditions (auditory variable), blurry and clean conditions (visual variable), and low- and high-context conditions (contextual variable). Results: Patients with NPH showed relatively good comprehension on the standardized comprehension test of PK-WAB-R. For the auditory word recognition tasks, there was a significant main effect of group, a significant within-group effect of auditory and contextual conditions, and significant interaction effects between auditory condition and group, auditory condition and contextual information, and auditory condition, contextual information, and group. Conclusion: This study confirmed that patients with NPH have difficulty processing auditory comprehension at the sentence level. In addition, the auditory word recognition performance in patients with NPH was significantly lower than HE, and that their difficulties may be more pronounced under certain conditions, such as noisy conditions and low contextual information. | Cho, Yoo-Jung; Park, Ki-Su; Kang, Kyunghun; Ha, Ji-Wan | Daegu Univ, Grad Sch Rehabil, Dept Speech & Language Pathol, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Neopons Inc, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Daegu Univ, Dept Speech Language Pathol, 201 Daegudae Ro, Gyongsan 38453, South Korea | 58666822200; 55932363100; 55365592200; 57072470300 | jw-ha@daegu.ac.kr; | COMMUNICATION SCIENCES AND DISORDERS-CSD | COMMUN SCI DISORD-CS | 2288-1328 | 2288-0917 | 29 | 1 | ESCI | AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY | 2024 | 0.5 | 98.6 | 1.96 | 2025-04-16 | 4 | 4 | Normal Pressure Hydrocephalus (NPH); Auditory word recognition; Visual interference; Auditory interference; Contextual information | Auditory interference; Auditory word recognition; Contextual information; Normal Pressure Hydrocephalus (NPH); Visual interference | English | 2024 | 2024-03 | 10.12963/csd.231017 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Information Retrieval Performance on Story Recall in Normal Aging | Objectives: The present study aimed to determine whether stimulus modality, age group, and time of performance differed in story recall performance in normal aging. Methods: Seventy-three healthy older adults were divided into two groups, 65-74 years old and 75+ years old, and randomly assigned to an auditory condition and an audiovisual condition to perform a story recall task. For each independent variable, event sequencing scores and total number of information units (IUs) were compared, and information-finding behaviors were categorized into reformulation, repetition, filler, and insertion in order to compare the frequency of production by type of information-finding behavior. Results: First, there was no significant difference between groups in event sequencing score according to modalities, age, and time interval. Second, there was no significant difference between groups in the total number of IUs according to modalities, age, and time interval, but all groups performed better on average in the second trials than in the first. Third, the frequencies of all types of information-finding behaviors decreased in the second trials compared to the first, and there was a significant difference between time intervals, especially in fillers and insertions. Conclusion: This study provides meaningful information about variables that should be considered when establishing norms for story recall assessment. | Park, Yu-Min; Cho, Yoo-Jung; Kim, Nayeon; Lee, Jiho; Park, Ki-Su; Yoon, Janghyeok; Ha, Ji-Wan | Daegu Univ, Grad Sch Rehabil, Dept Speech & Language Pathol, Gyongsan, South Korea; Neopons Inc, AI Lab, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Konkuk Univ, Dept Ind Engn, Seoul, South Korea | ; Park, Yumin/LLL-7733-2024 | 59532928400; 58666822200; 57072206000; 57221320001; 55932363100; 36451492000; 57072470300 | jw-ha@daegu.ac.kr; | COMMUNICATION SCIENCES AND DISORDERS-CSD | COMMUN SCI DISORD-CS | 2288-1328 | 2288-0917 | 29 | 4 | ESCI | AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY | 2024 | 0.5 | 98.6 | 1.8 | 2025-05-07 | 2 | 2 | Story recall; Information retrieval; Event sequencing; IU (Information unit); Information-finding behaviors | MILD COGNITIVE IMPAIRMENT; MODALITY; ADULTS | Event sequencing; Information retrieval; Information-finding behaviors; IU (Information Unit); IU (Information unit); Story recall; 이벤트시퀀싱; 이야기 회상; 정보인출능력; 정보찾기 행동 | Korean | 2024 | 2024-12 | 10.12963/csd.240078 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Lexical Retrieval Performance in Patients with Normal Pressure Hydrocephalus and Parkinson's Disease | Objectives: This study aimed to investigate lexical retrieval performance in patients with similar patterns but different central nervous system degenerative diseases, specifically normal pressure hydrocephalus (NPH) and Parkinson's disease (PD). Methods: A lexical retrieval task was performed on 14 patients with NPH, 14 patients with PD, and 14 healthy elderly subjects (HE) to compare their correct response scores, reaction times, and error types, and the Korean-Boston naming test (K-BNT) was additionally performed to deter-mine the validity of the lexical retrieval task. Results: First, there was no significant difference in scores between the three groups on the K-BNT. Second, the scores of the NPH and PD groups were significantly lower than the HE group on the lexical retrieval task. Third, only the NPH group was significantly slower than the HE group in the reaction time on the lexical retrieval task. Fourth, the error type analysis showed that the NPH group made significantly more semantic and nonword errors and the PD group made significantly more semantic errors than the HE group. Fifth, the correlation analysis showed a significant static correlation between K-BNT and the lexical retrieval task scores with a correlation coefficient of .721. Conclusion: We suggest that the lexical retrieval task may be useful in the screening and differential diagnosis of patients with NPH and PD. | Kim, So-Hee; Park, Ki-Su; Kang, Kyunghun; Yoon, Janghyeok; Ha, Ji-Wan | Daegu Univ, Grad Sch Rehabil, Dept Speech & Language Pathol, Gyongsan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Neopons Inc, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Konkuk Univ, Dept Ind Engn, Seoul, South Korea; Daegu Univ, Dept Speech Language Pathol, 201 Daegudae Ro, Gyongsan 38453, South Korea | 59147663100; 55932363100; 55365592200; 36451492000; 57072470300 | jw-ha@daegu.ac.kr; | COMMUNICATION SCIENCES AND DISORDERS-CSD | COMMUN SCI DISORD-CS | 2288-1328 | 2288-0917 | 29 | 1 | ESCI | AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY | 2024 | 0.5 | 98.6 | 0.98 | 2025-04-16 | 3 | 3 | Normal pressure hydrocephalus; Parkinson's disease; Lexical retrieval ability; Reaction time; Error types | DIAGNOSIS; ACCESS | Error types; Lexical retrieval ability; Normal pressure hydrocephalus; Parkinson’s disease; Reaction time; 반응시간; 어휘인출능력; 오류유형; 정상압수두증; 파킨슨병 | English | 2024 | 2024-03 | 10.12963/csd.240006 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The Performance of Story Information Retrieval in Patients with Parkinson's Disease and Normal Pressure Hydrocephalus | Objectives: The purpose of this study was to determine whether a story information retrieval task can be used to sensitively detect cognitive and language decline in patients with Parkinson's disease (PD) and normal pressure hydrocephalus (NPH) and to differentially diagnose the two groups. Methods: To assess participants' real-life cognitive and language abilities, we used the story information retrieval task, which involves showing a video of a story and then asking for information about it. The task was administered to 60 participants, 20 each of the healthy elderly (HE), PD patients, and NPH patients. We then compared the performance of story information retrieval among the three groups in terms of full and partial information frequencies, the total score, and scores by information type. And the correlation with the Korean version of the mini-mental state examination, 2nd edition (K-MMSE-2) was analyzed to check the validity of the story information retrieval task. Results: The PD and NPH groups performed significantly worse than the HE group on the story information retrieval, whether measured by frequency or total score. However, when compared by information type, only the NPH and HE groups showed significant differences. Conclusion: By assessing story information retrieval performance, we were able to identify language and cognitive decline in PD and NPH patients. And the study also showed that the two patient populations may perform differently when evaluated by information type. | Cho, Yoo-Jung; Kim, Nayeon; Lee, Jiho; Park, Ki-Su; Kang, Kyunghun; Yoon, Janghyeok; Ha, Ji-Wan | Daegu Univ, Grad Sch Rehabil, Dept Speech & Language Pathol, Gyongsan, South Korea; Neopons Inc, AI Lab, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurol, Daegu, South Korea; Konkuk Univ, Dept Ind Engn, Seoul, South Korea; Daegu Univ, Dept Speech & Language Pathol, 201 Daegudae Ro, Gyongsan 38453, South Korea | 58666822200; 57072206000; 57221320001; 55932363100; 55365592200; 36451492000; 57072470300 | jw-ha@daegu.ac.kr; | COMMUNICATION SCIENCES AND DISORDERS-CSD | COMMUN SCI DISORD-CS | 2288-1328 | 2288-0917 | 29 | 4 | ESCI | AUDIOLOGY & SPEECH-LANGUAGE PATHOLOGY | 2024 | 0.5 | 98.6 | 1.8 | 2025-05-07 | 2 | 2 | Parkinson's disease; Normal pressure hydrocephalus; Story and discourse; Story information retrieval | RECALL | Normal pressure hydrocephalus; Parkinson’s disease; Story and discourse; Story information retrieval; 이야기 담화; 이야기 정보인출; 정상압수두증; 파킨슨병 | Korean | 2024 | 2024-12 | 10.12963/csd.240080 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
