| ○ | Proceedings Paper | FABRICATION OF ELECTRICALLY CONDUCTIVE PATTERNS ON ABS POLYMER USING LOW-PRESSURE COLD SPRAY AND ELECTROLESS PLATING | Previous studies have shown that metallic coatings can be successfully cold sprayed onto several polymer substrates. The electrical performance of the cold-sprayed polymers, however, is not generally sufficient enough to utilize them as an electronic device. In this paper, an environment-friendly metallization technique has been proposed to fabricate conductive metal patterns onto polymer substrates combining cold spray deposition and electroless plating to address that challenge. Copper feedstock powder was cold sprayed onto the surface of the acrvlonitrile-butadiene-styrene (ABS) parts. The as-cold sprayed powders then served as the activating agent for selective electroless copper plating (ECP) to modify the the surface of the polymers to be electrically conductive. A series of characterizations are conducted to investigate the morphology, analyze the surface chemistry, and evaluate the electrical performance and adhesion performance of the fabricated coatings. After 6 hours of ECP, the sheet resistance and resistivity of copper patterns on the ABS parts were measured as 2.854 m Omega/sq and 6.699x 10(-7) Omega m respectively. Moreover, simple electrical circuits were demonstrated for the metallized ABS parts through the described method. The results show that low-pressure cold spray (LPCS) and ECP processes could be combined to fabricate electrically conductive patterns on ABS polymer surfaces in an environmental-friendly way. | Akin, Semih; Jun, Martin Byung-Guk; Tsai, Jung-Ting; Park, MinSoo; Jeong, Young Hun | Purdue Univ, Sch Mech Engn, W Lafayette, IN 47906 USA; Purdue Univ, Sch Mat Engn, W Lafayette, IN 47906 USA; Seoul Natl Univ Sci & Technol, Dept Mech Syst Design Engn, Seoul, South Korea; Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | Tsai, Jung-Ting/KIE-8368-2024; Akin, Ph.D., Semih/JMC-7923-2023; Jeong, Young/R-2486-2019; Akin, Semih/JMC-7923-2023 | mbgjun@purdue.edu; | PROCEEDINGS OF THE ASME 2020 15TH INTERNATIONAL MANUFACTURING SCIENCE AND ENGINEERING CONFERENCE (MSEC2020), VOL 2B | 0 | ABS; cold spray; electroless plating; metallization; polymer | METALLIZATION; DEPOSITION; PLASTICS; SURFACE; COATINGS | English | 2020 | 2020 | 바로가기 | ||||||||||||||||||||||

| ○ | ○ | Article; Proceedings Paper | Fabrication of Electrically Conductive Patterns on Acrylonitrile-Butadiene-Styrene Polymer Using Low-Pressure Cold Spray and Electroless Plating | Previous studies have shown that metallic coatings can be successfully cold sprayed (CS) onto several polymer substrates. However, the electrical performance of the cold-sprayed polymers is not generally enough to utilize them as an electronic device. In this study, an environment-friendly metallization technique has been proposed to achieve highly electrically conductive metal patterns onto polymer substrates using cold spray deposition and subsequent electroless copper plating (ECP). Copper feedstock powder was CS onto the surface of the acrylonitrile-butadiene-styrene (ABS) parts. The as-CS powders then served as the activating agent for the selective ECP to modify the surface of the polymers to be electrically conductive. A series of characterizations were conducted to investigate the morphology, analyze the surface chemistry, evaluate the electrical performance, mechanical adhesion, and mechanical strength performance of the fabricated coatings. Moreover, simple electrical circuits were presented for the ABS parts through the described method. Findings demonstrated that low-pressure cold spray copper deposition followed by the ECP processes could be used as an environmental-friendly manufacturing method of electrically conductive patterns on ABS polymer.

| ○ | Article | Fabrication of nafion-coated a SWCNT gas sensor and evaluation of the measurement of the extent of decay of fish | Single-walled carbon nanotubes (SWCNTs) have different electrical properties through surface reactions with ambient gases because of defects formed on the surface. The sensitivity of SWCNTs to gases varies depending on the presence or absence of a Nafion coating. In this study, a SWCNT gas sensor was fabricated to measure the extent of decay of fish. Ammonia (NH3) and trimethylamine (N(CH3)3, TMA) gases are released from fish as they decay. To confirm the applicability of the gas sensor to decaying fish, we investigated the reactivity of the designed SWCNT gas sensor to ammonia and TMA. To measure the extent of decay of fish, replaced a piece of mackerel of a certain size in a container maintained at 30 °C, together with a SWCNT gas sensor, and we allowed the mackerel to decay naturally. The characteristics of the fabricated SWCNT gas sensor in the presence of decaying mackerel was monitored over time. The change in the electrical characteristics of the SWCNT gas sensor due to the decayed mackerel, along with the characteristics identified in TMA gas, confirmed the applicability of the gas sensor to measurements of fish spoilage. © 2020 The Korean Physical Society.

| ○ | Conference paper | Fabrication of porous poly lactic-co-glycolic acid (PLGA) coated SUS microneedles for improving transdermal drug delivery | This study reports a simple coating method of stainless steel (SUS) microneedles (MNs) with porous PLGA polymer to create uniform porous layer on microneedle in order to provide higher delivery rates. MNs were coated with a thin porous PLGA layer to impart the resultant MNs with high mechanical strength and enhanced delivery rates. Calcein dye was successfully delivered into porcine skin to a depth of 750 μm by the porous-coated MNs, demonstrating that the developed MNs can pierce skin easily. Additionally, lidocaine delivery in phosphate buffered saline (PBS) by porous-coated MNs was increased 25 times than that of non-coated MNs. © 17CBMS-0001. | Ullah, Asad; Kim, Chul Min; Kim, Gyu Man | School of Mechanical Engineering, Kyungpook National University, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea; School of Mechanical Engineering, Kyungpook National University, South Korea | 56820305400; 59316640400; 55664733000 | gyuman.kim@knu.ac.kr; | 21st International Conference on Miniaturized Systems for Chemistry and Life Sciences, MicroTAS 2017 | 0 | 2025-06-25 | 0 | Drug delivery; Polymer coating; Porous structure; SUS microneedles | Controlled drug delivery; Drug delivery; Needles; Targeted drug delivery; Coating methods; High mechanical strength; Microneedles; Phosphate-buffered salines; Poly lactic-co-glycolic acid; Polymer Coating; Porous structures; Transdermal drug delivery; Plastic coatings | English | Final | 2020 | 바로가기 | ||||||||||||||||||||
| ○ | ○ | Proceedings Paper | Fabrication of tunable and wearable strain sensor for adjusting photo-polymerization | Wearable strain sensors are attracting great attention owing to their remarkable applications in physiological-monitoring and motion-sensing. However, there are two limitations for the fabrication of wearable strain sensors because additional material synthesis process and additional adhesive material are necessary. In this presentation, we introduce the method for the fabrication of wearable and attachable strain sensors without additional process and material. By controlling laser parameters, we successfully fabricated wearable and attachable sensors consisting of silver nanowires and polymer having diverse mechanical and adhesive properties. Our work helps guide fabricating nanowire-based resistive wearable strain sensors using the laser-based 3D printing. | Hwang, T.; Kong, H.; Hwang, S.; Yeo, J. | Kyungpook Natl Univ, Dept Phys, Novel Appl Nanoopt NANO Lab, 80 Daehakro, Bukgu 41566, Daegu, South Korea | Yeo, Junyeob/I-1287-2013 | 57211068047; 57552927300; 57211075602; 58692645200 | LASER 3D MANUFACTURING VII | 0277-786X | 1996-756X | 11271 | 0 | 2025-06-25 | 0 | 0 | Tunable; wearable; strain sensor; stereolithography | Stereolithography; Strain sensor; Tunable; Wearable | 3D printers; Adhesives; Fabrication; Photopolymerization; Silver nanowires; 3-D printing; Adhesive materials; Adhesive properties; Laser parameters; Laser-based; Material synthesis; Motion sensing; Strain sensors; Wearable sensors | English | 2020 | 2020 | 10.1117/12.2544249 | 바로가기 | 바로가기 | 바로가기 | |||||||||||

| ○ | ○ | Article | Facile synthesis of Ce-doped α-cobalt hydroxide nanoflakes battery type electrode with an enhanced capacitive contribution for asymmetric supercapacitors | The nanostructure of layered cobalt hydroxide has been gaining increasing attention in the field of electrochemical energy storage due to its high surface area and compatible cages for the redox reactions. Nevertheless, its poor electrical conductivity hinders application toward rate performance. In this work, cerium (Ce)-doped alpha-cobalt hydroxide (alpha-Co(OH)(2)) thin-film electrodes were prepared with improved rate capability via electrodeposition method. To investigate the effect of Ce doping on the structural, morphological and electrochemical properties of alpha-Co(OH)(2), it was doped in different molar percentages ranging from 0 to 3 mol%. The alpha-Co(OH)(2) doped with 1 mol% Ce showed an excellent charge storage performance with a specific capacity of 415 C g(-1) and the relatively higher cyclic stability of 73%. The deconvolution of capacitive and diffusion-controlled contributions has been performed using step potential electrochemical spectroscopy which showed the capacitive contribution of the film increased from 38% to 45% when doped with Ce by 1 mol%. This improved capacitive contribution of alpha-Co(OH)(2) battery-type electrode can facilitate high power performance without compromising the specific energy of the supercapacitor. Finally, this electrode was employed for the fabrication of asymmetric supercapacitor that showed excellent cyclic stability, specific energy and power. | Rohit, R.

| ○ | Article | Factors Affecting Health Behavior of Patients with Stroke: Focusing on Health Literacy of Patients and Family Caregivers | Purpose: This study aimed to identify how health literacy in patients with stroke and their family caregivers influences their health behavior. Methods: A total of 95 patient-family caregiver dyads were recruited from March to September 2018. Health literacy was measured using the newest vital sign and the health behavior scale was used to identify the health behavior of patients. Data were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson’s correlation, and multiple regression. Results: The mean age of patients with stroke and family caregivers was 69.44±8.25 and 54.01±14.42 years, respectively. The proportion of women in the family caregivers was 72.6%. The average health literacy score of patients with stroke and their family caregivers was 2.26±1.75 and 3.03±1.97, respectively. The multiple regression analysis revealed that patients’ interest in health (p <.001), health literacy (p=.037), age (p=.001), and caregivers’ gender (p=.028) were the significant factors influencing health behavior of patients with stroke. Conclusion: In providing optimal care, nurses must ensure that information is provided to both patients and their family caregivers in a clear and effective manner. To improve health behavior in patients with stroke, various strategies are needed to increase their interest in health while considering their age and health literacy. © 2020.

| ○ | ○ | Article | Factors Affecting Intraocular Pressure after Laser Iridotomy in Fellow Eye with Acute Angle Closure Glaucoma | Purpose: To investigate the factors affecting intraocular pressure (IOP) change after prophylactic laser iridotomy (LI) in the fellow eye with acute angle closure glaucoma. Methods: Twenty-three subjects with acute primary angle closure glaucoma, who had undergone prophylactic LI in the fellow eye were enrolled in this study. IOP was measured before and 1 week after prophylactic LI. Compared with a week after and before the prophylactic LI, eleven eyes with the IOP reduction of 20% or more were classified into A group and twelve eyes with an IOP reduction of 20% or less were classified as B group. Anterior segment parameters were measured using anterior segment swept source optical coherence tomography. Results: The mean age, the best corrected visual acuity, the baseline IOP and the axial length were not significantly different between the two groups (p > 0.05). The IOP after prophylactic LI was significantly different between the two groups (group A 11.36 +/- 1.96 mmHg, Group B 13.50 +/- 1.83 mmHg; p = 0.013). There was a significant difference in IOP change rate of the two groups (Group A 29.78 +/- 11.09%, Group B 9.14 +/- 5.91%; p < 0.001). In multiple regression analysis, only the anterior chamber depth was significantly associated with the IOP change rate (p = 0.011). Conclusions: The anterior chamber depth is associated with the change of IOP after prophylactic LI in the fellow eye with acute primary angle closure glaucoma. If the anterior chamber depth is shallow, it is highly likely that the change of IOP is relatively small. Therefore, the anterior chamber depth must be considered in assessing the effectiveness of prophylactic LI. | Kim, Yu Min; Kim, Dai Woo | Kyungpook Natl Univ, Dept Ophthalmol, Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea | 57211041082; 57095192800 | proector97@gmail.com; | JOURNAL OF THE KOREAN OPHTHALMOLOGICAL SOCIETY | J KOR OPHTHALMOL SOC | 0378-6471 | 2092-9374 | 61 | 12 | ESCI | OPHTHALMOLOGY | 2020 | N/A | 0 | 2025-06-25 | 0 | 0 | Acute angle closure glaucoma; Anterior chamber depth; Prophylactic laser iridotomy | PERIPHERAL IRIDOTOMY; PHACOEMULSIFICATION; POPULATION; PREVALENCE | Acute angle closure glaucoma; Anterior chamber depth; Prophylactic laser iridotomy | Korean | 2020 | 2020-12 | 10.3341/jkos.2020.61.12.1493 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Factors influencing clinical nurses' advocacy for people with disability | Purpose: Clinical nurses are the ideal health care providers to advocate for vulnerable and underserved populations such as people with disability. This study aimed to understand factors influencing nursing advocacy for people with disability among clinical nurses. Methods: The subjects of this study were 186 clinical nurses who were working in three hospitals in B and D cities. Self-report questionnaires were used to collect the data. Data were analyzed using IBM SPSS Statistics 25 with descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficients, and multiple regression analysis. Results: Clinical experience and esthetical nursing competency have positive correlations with nursing advocacy, and optimism-human rights has a negative correlation with nursing advocacy. Factors influencing nursing advocacy for people with disability were identified as patient directivity (β=0.36, p=.001), optimism-human rights (β=-0.18, p=.008) and clinical experience (≥10) (β=0.14, p=.036). The final model consisting of these factors explained 19% of the variance of nursing advocacy (F=14.99, p=.001). Conclusion: The findings of this study indicate the importance of developing and implementing nursing interventions that can improve patient directivity and optimism-human rights toward people with disability among clinical nurses. These nursing advocacy interventions can be provided as part of continuing education as well as the nursing curriculum. © 2020, Official of Journal of Korean Academic Society of Nursing Education.

| ○ | ○ | Proceedings Paper | Faster R-CNN Based Fault Detection in Industrial Images | Industry 4.0 requires smart environment to find defects or faults in their products. A defective product in the market can impact negatively on the overall image of the industry. Thus, there is continuous struggle for industrial environment to reduce impulsive downtime, concert deprivation and safety risks. Defect detection in industrial products using the images is very hot topic in era of current research. Machine learning provides various solution but most of the time such solutions are not suitable for environment where product is on conveyor belt and traveling from one point to another. To detect fault using industrial images, we proposed a method which is based on Faster R-CNN which is suitable for smart environment as it can the product efficiently. We simulated our environment using python language and proposed model has almost 99% accuracy. To make our proposed scheme adaptable for the industry 4.0, we also developed an android application which make it easy to interact with the model and industry can train this model according to their needs. Android application is able to take pictures of defective product and feed it to model which improve accuracy and eventually reduces time identify defective product. | Saeed, Faisal; Paul, Anand; Rho, Seungmin | Kyungpook Natl Univ, Dept Comp Sci & Engn, Daegu, South Korea; Sejong Univ, Dept Software, Seoul, South Korea | Paul, Anand/V-6724-2017 | 58165089300; 56650522400; 10738984000 | bscsfaisal821@gmail.com;paul.editor@gmail.com;smrho@sejong.edu; | TRENDS IN ARTIFICIAL INTELLIGENCE THEORY AND APPLICATIONS.

| ○ | Article | FINDING EXPLICIT SOLUTIONS FOR LINEAR REGRESSION WITHOUT CORRESPONDENCES BASED ON REARRANGEMENT INEQUALITY | A least squares problem without correspondences is expressed as the following optimization: min parallel to A x - Pi y parallel to , Pi is an element of P m , x is an element of R n where A is an element of R mxn and y is an element of R m are given. In general, solving such an optimization problem is highly challenging. In this paper we use the rearrangement inequalities to find the closed form of solutions for certain cases. Moreover, despite the stringent constraints, we successfully tackle the nonlinear least squares problem without correspondences by leveraging rearrangement inequalities. | Kim, Mijin; Lee, Hyungu; Choi, Hayoung | Kyungpook Natl Univ, Dept Math, Daegu 41566, South Korea | Choi, Hayoung/U-7046-2019 | rlamj0922@knu.ac.kr;lewis9910@knu.ac.kr;hayoung.choi@knu.ac.kr; | JOURNAL OF APPLIED MATHEMATICS & INFORMATICS | J APPL MATH INFORM | 2734-1194 | 2234-8417 | 42 | 1 | ESCI | MATHEMATICS, APPLIED | 2020 | N/A | 0 | Permuted linear model; shuffled regression; rearrangement inequality; least squares; optimizatoin | English | 2020 | 2020 | 10.14317/jami.2024.149 | 바로가기 | 바로가기 | 바로가기 | |||||||||||
| ○ | Article | Finite element analysis of heating with randomly incident microwaves | Microwave heating is a common method of heating in modern industrial and household applications nowadays. Long before the recent invention of Randomly Incident Microwaves (RIM), conventional Parallel Incident Microwaves (PIM) have been used as a power transferring method. PIMs have some drawbacks: uneven heating, sparking problems with sharp conducting bowls, and well-known law of energy balance and some reasonable assumptions, the analysis of heating with RIM reduces to a simple heat transfer equation, solvable by common commercial software. The set of heat generations for each finite element can be obtained by simple computation while considering the attenuation and focusing effects of microwaves. Several examples of finite element analysis were performed for fully open-type media and partially open-type media. The temperature contours of each case are provided to compare the effect of space between heated pine tree logs. © 2020 Praise Worthy Prize S.r.l. | Park, Sangjun; Kim, Jaehwan; Lim, Heemin; Kwon, Youngdoo; Cho, Heekeun | School of Forest Sciences and Landscape Architecture, College of Agriculture and Life Sciences, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, South Korea; College of Agriculture and Life Science, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, South Korea; Department of Forestry, Graduate School, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, South Korea; Department of Mechanical Engineering, Kyungpook National University, 80 Daehak-ro, Buk-gu, Daegu, South Korea; Department of Mechanical Engineering Education, Andong National University, 1375 Gyeongdond-ro, Andong-si, Kyungpook, South Korea | 57209022140; 57222962141; 57222960516; 7403459206; 12143735900 | hkcho@anu.ac.kr; | International Review of Mechanical Engineering | 1970-8734 | 14 | 12 | 0.32 | 2025-06-25 | 3 | Finite element method; Heating; Microwaves; Pine wilt disease; Randomly incident wave | English | Final | 2020 | 10.15866/ireme.v14i12.18150 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Book chapter | Finite element simulation of water content-influenced progressive failure of sensitive clays | Large-scaled landslides often occur in sensitive clay deposits in horsts and grabens, typical of spreads. Most large deformation numerical analysis based on the strain-softening behavior of undrained shear strength. In practice, water infiltration into soils may result a variation of non-uniform crack and shear band emergence at a low soil resistance. In this study, the mechanism of water content effect on the stress-strain relationship was implemented in Mohr-Coulomb (M-C) model using the user material subroutine of the commercial software Abaqus/Explicit. The coupled Eulerian-Lagrangian method (CEL) was used to model such large deformation analysis. The developed model was verified by a simulation of Saint-Jude landslide, which occurred in 2010 in Quebec, Canada. There was a good agreement among numerical results with water content effect comparing to an analytical function. A larger mobile soil mass movement with a significant reduction of soil resistance was simulated successfully using the developed model. © Springer Nature Singapore Pte Ltd. 2020. | Doan, Nhat-Phi; Woo, Seung-Wook; Hou, Yao-Long; Park, Sung-Sik | School of Architectural, Civil, Environmental, and Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Architectural, Civil, Environmental, and Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; School of Architectural, Civil, Environmental, and Energy Engineering, Kyungpook National University, Daegu, 41566, South Korea; Department of Civil Engineering, Kyungpook National University, Daegu, 41566, South Korea | 58095587400; 57212917862; 57210563078; 36241850300 | phidoan.ksxd@gmail.com; | Lecture Notes in Civil Engineering | 2366-2557 | 54 | 1.37 | 2025-06-25 | 3 | Progressive failure; Sensitive clays; Water content effect | ABAQUS; C (programming language); Clay deposits; Deformation; Failure (mechanical); Finite element method; Lagrange multipliers; Landslides; Soils; Subroutines; Eulerian-Lagrangian method; Finite element simulations; Large deformation analysis; Progressive failure; Sensitive clays; Stress-strain relationships; Undrained shear strength; User material subroutine; Stress-strain curves | English | Final | 2020 | 10.1007/978-981-15-0802-8_134 | 바로가기 | 바로가기 |
