| ○ | Article | Effect of Eco-friendly Inorganic Flame Retardants on Mechanical and Flame-Retardant Properties of EPDM Compound | In this study, the mechanical and flame-retardant properties of ethylene-propylene-diene-termonomer (EPDM) based rubber compounds and various other environmentally friendly inorganic flame retardants were investigated. Alumina trihydrate (ATH) and magnesium hydroxide (MDH) were used as inorganic flame retardants. The mechanical properties after thermal oxidation aging and the flame-retardant properties of the EPDM compounds were measured using a moving die rheometer, a universal testing machine, a compression set, and a UL 94 V flammability test. We focused on how the properties were affected by the type and amount of flame retardants. The results demonstrated that the optimal mechanical and flame-retardant V-0 grade properties were obtained at an ATH content of 200 phr. | Do, Jong Hwan; Kim, Do Young; Seo, Kwan Ho | DATWYLER Sealing Solut, Mat Dev Team, 26,Seongseoseo Ro 15 Gil, Daegu 42718, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, 80 Daehak Ro, Daegu 41566, South Korea | ; , Do Young Kim/AAB-1459-2021 | khseo@knu.ac.kr; | ELASTOMERS AND COMPOSITES | ELASTOM COMPOS | 2092-9676 | 2288-7725 | 55 | 1 | ESCI | POLYMER SCIENCE | 2020 | N/A | 5 | EPDM; mechanical properties; flame retardant; burn test | POLYMERS | Korean | 2020 | 2020-03 | 10.7473/ec.2020.55.1.40 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | Conference paper | Effect of electroless ni-p plating on the bonding strength of pbte thermoelectric module using silver alloy-based brazing | This study investigates a brazing method for manufacturing PbTe thermoelectric modules using a Ag-based filler metal with a melting point of about 650 ℃. To improve the bonding strength between the Ag-based brazing layer and the PbTe thermoelectric module, an electroless Ni-P plating layer is formed on the surface of the thermoelectric module as a diffusion barrier layer. The bonding strength of the PbTe thermoelectric module manufactured by the electroless Ni-P plating and Agbased brazing has a high value of approximately 8.3 MPa. No defects such as pores or cracks were observed at the bonding interface between the thermoelectric element and the brazing layer. Furthermore, because of the high bonding strength of the manufactured thermoelectric module, fractures occur inside the thermoelectric element rather than at the bonding interface. Accordingly, the electroless Ni-P plating and Ag-based brazing method proposed in this study is found to be effective in manufacturing PbTe-based thermoelectric modules with high bonding strength. © 2020 Trans Tech Publications Ltd, Switzerland. | Hwa Bae, Sung; Young Choi, Joon; Son, Injoon | School of Materials Science and Engineering, Kyungpook National University, 80 Daehakro, Buk-gu, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, 80 Daehakro, Buk-gu, Daegu, 41566, South Korea; School of Materials Science and Engineering, Kyungpook National University, 80 Daehakro, Buk-gu, Daegu, 41566, South Korea | 57210171283; 57498971200; 9942975800 | Materials Science Forum | 0255-5476 | 985 MSF | 1.26 | 2025-06-25 | 2 | Bonding strength; Brazing; Pb-Te; Thermoelectric module | Brazing; Diffusion barriers; Diffusion bonding; Filler metals; IV-VI semiconductors; Lead compounds; Nickel compounds; Physical properties; Plating; Silver alloys; Silver compounds; Thermoelectric equipment; Thermoelectricity; Ag-based filler metal; Bonding interfaces; Bonding strength; Diffusion barrier layers; Electroless ni-p plating; Thermo-electric modules; Thermoelectric element; Tellurium compounds | English | Final | 2020 | 바로가기 | |||||||||||||||||||
| ○ | Article | Effect of extraction conditions on ultrasonic-Assisted extraction of polyphenolic compounds from okra (Abelmoschus esculentus L.) leaves | The effects of extraction conditions on ultrasonic-Assisted extraction (UAE) of polyphenolic compounds from okra leaves (OKL) were investigated. Dried OKL powder was extracted using different conditions, including ethanol concentration (20-100%), sample-To-solvent ratio (1:10-1:40 g/mL), UAE temperature (10-70°C) and time (15-75 min); and their effects on total phenolic (TPC) and flavonoid (TFC) contents, as well as the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activities, were examined via a single-factor design. The principal component analysis (PCA) was useful in indicating the optimal extraction parameters and aided a clearer understanding of correlative relationships between the extraction variables. The results showed all extraction conditions to have significant effects on OKL polyphenolics yield and antioxidant activities. The extraction conditions of 60% ethanol, 1:40 g/mL solid-To-solvent, at 70°C for 30 min, favored OKL polyphenolics recovery and antioxidant stability. At this optimal condition, the values for OKL extract yield, TPC, TFC, DPPH, and ABTS were 31.50%, 13.21 mg GAE/g, 29.57 mg RE/g, 16.86 mg AAE/g and 31.90 mg AAE/g, respectively. PCA result substantiated the results obtained for optimal extraction conditions and informed a close correlation between OKL polyphenolics and antioxidant activity. Moreover, chlorogenic acid, p-coumaric, and catechin were identified as the major polyphenols in OKL. Conclusively, optimal UAE conditions for OKL polyphenols were obtained, and this could provide a basis for the utilization of OKL as a potential functional material. © 2020 Korean Society of Food Preservation.

| ○ | Conference paper | Effect of Fatigue of the Protective Clothing Wearer on Body Balance Performance Caused by Shorten or Prolonged Workload with Heat Exposure | This study aimed to investigate the effect of fatigue on body balance performance caused by shorten and prolonged workload with heat exposure. Shorten and prolonged experiments were conducted for the present study. Ten healthy men participated in the experiment for exploring of deterioration of balance ability by physiological and psychological fatigue due to heat exposure with wearing protective clothing for construction sites. The main finding of this study indicates that body balance performance was affected by shorten and prolonged workload with heat exposure. The core temperature and body weight loss measured during workload with heat exposure were significantly high. The body sway parameters showed a similar tendency, although the differences were not significant. Accumulation of fatigue from prolonged stress from workload and heat exposure seems to contribute to the decline in body balance performance. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG. | Son, Suyoung; Tokizawa, Ken | Department of Home economics Education, Teachers College, Kyungpook National University, Daehak-ro 80, Buk-gu, Daegu, South Korea; National Institute of Occupational Safety and Health, Japan, Nagao, 6-21-1, Tama-ku, Kawaski, 214-8585, Japan | 54785259200; 6508096459 | sonsy@knu.ac.kr; | Advances in Intelligent Systems and Computing | 2194-5357 | 1202 AISC | 0 | 2025-06-25 | 0 | Body balance; Fatigue; Heat exposure; Workload test | Clothes; Deterioration; Human engineering; Protective clothing; Textiles; Balance performance; Body sway; Body weight loss; Construction sites; Core temperature; Heat exposure; On-body; Product design | English | Final | 2020 | 10.1007/978-3-030-51194-4_110 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Effect of foliar application of potassium fertilizers on soybean plants under salinity stress | Soybean, one of the major food and fodder crops, yield is significantly reduced by different abiotic and biotic stresses, and salinity is one of the major abiotic stresses. The research objective of this study was to investigate the effect of foliar application of potassium chloride and potassium sulfate fertilizers at the early growth stage of soybean under medium (6 dS/m) and high (12 dS/m) salinity stresses. The effect of fertilizer application was measured on the bases of plant growth, levels of antioxidant activities, total polyphenol, flavonoid, chlorophyll, and carotenoid contents. Potassium sulfate showed better positive effect on the antioxidant activities, polyphenol, flavonoid, carotenoid, and chlorophyll contents compared to those of potassium chloride although the contribution was not noteworthy in comparison to the fertilizer unsprayed plants. The results of this study implied that foliar applications of 2.5% potassium fertilizers could not help reduce the negative effect of salinity stress at the early stage of soybean growth. This study suggests further researches using different concentrations of fertilizers at different plant growth and development stages. © 2018 | Adhikari, Bishnu; Dhungana, Sanjeev Kumar; Kim, Il-Doo; Shin, Dong-Hyun | School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea; International Institute of Agriculture Research & Development, Kyungpook National University, Daegu, 41566, South Korea; School of Applied Biosciences, Kyungpook National University, Daegu, 41566, South Korea | 57195228054; 56269940800; 56269995600; 7403352903 | dhshin@knu.ac.kr; | Journal of the Saudi Society of Agricultural Sciences | 1658-077X | 19 | 4 | 5.65 | 2025-06-25 | 65 | Foliar application; Salinity; Soybean; Stress; Vegetative growth | English | Final | 2020 | 10.1016/j.jssas.2019.02.001 | 바로가기 | 바로가기 | ||||||||||||||||
| ○ | Article | Effect of High-Speed Blade Coating on Electrical Characteristics in Polymer Based Transistors | We explore the effect of high-speed blade coating on electrical characteristics of conjugated polymer-based thin-film transistors (TFTs). As the blade-coating speed increased, the thickness of the polymer thin-film was naturally increased while the surface roughness was found to be unchanged. Polymer TFTs show two remarkable tendencies on the magnitude of field-effect mobility with increasing blade-coating speed. As the blade-coating speed increased up to 2 mm/s, the field-effect mobility increased to 4.72 cm(2)V(-1)s(-1). However, when the coating speed reached 6 mm/s beyond 2 mm/s, the field-effect mobility rather decreased to 3.18 cm(2)V(-1)s(-1). The threshold voltage was positively shifted from 2.09 to 8.29 V with respect to increase in blade-coating speed. | Park, Jun-Ik; Jeong, Hyun-Seok; Vincent, Premkumar; Park, Jihwan; Kim, Do-Kyung; Jang, Jaewon; Kang, In Man; Kim, Hyeok; Kim, Yun-Hi; Lang, Philippe; Bae, Jin-Hyuk | Kyungpook Natl Univ, Sch Elect Engn, Daegu 41566, South Korea; Gyeongsang Natl Univ, Dept Elect Engn, Jinju 52828, South Korea; Gyeongsang Natl Univ, Dept Chem, Jinju 52828, South Korea; Gyeongsang Natl Univ, Res Inst Nat Sci, Jinju 52828, South Korea; Univ Paris Diderot Paris 7, UMR 7086, CNRS, ITODYS, F-75205 Paris 13, France | Kim, Yun-Hi/AAP-1769-2021; Vincent, Premkumar/C-3190-2019; lang, philippe/E-5192-2012 | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 9 | 1 | Organic TFTs; Blade Coating Speed; Donor-Acceptor Polymers; Solution-Process | FIELD-EFFECT TRANSISTORS; THIN-FILM TRANSISTORS; UNIAXIAL ALIGNMENT; THICKNESS; PERFORMANCE; SEMICONDUCTORS; PENTACENE | English | 2020 | 2020-09 | 10.1166/jnn.2020.17615 | 바로가기 | 바로가기 | |||||||||||||||||
| ○ | Article | Effect of Incorporating Zirconia Powder into a Primer on the Resin Bond Strength to Zirconia Ceramic | The adhesion property of zirconia powder-incorporated primers was investigated in vitro with the aim of enhancing the resin bond strength to zirconia ceramic. A commercial zirconia primer was modified through the addition of 0 (control), 5, 10, 25, and 50 wt% of a zirconia powder ( codes: ZP0, ZP5, ZP10, ZP25, and ZP50, respectively). Prior to primer modification, the powder was characterized via differential scanning calorimetry (DSC) and Fourier-transform infrared (FTIR) spectrophotometry. The surfaces of dental zirconia ceramic discs were air-abraded and treated with one of the five primers. One resin composite cylinder (diameter: 2.38 mm) was bonded on one specimen surface (n = 12/group). The bonded specimens were all stored for 24 h in distilled water at 37 degrees C and subjected to 5000 thermal cycles prior to shear bond strength (SBS) testing. The DSC and FTIR analyses confirmed that the zirconia powder contained an organic binder. The SBS test results showed that the groups could be arranged as follows, ZP25 > ZP10 > ZP5 > ZP0, i.e., in descending order of the mean value. The lowest SBS value was obtained for the ZP50 group. The results suggest that the incorporation of a zirconia powder into a primer represents a promising modification method for improving the resin bond strength to zirconia ceramic. | Lee, Eunkyung; Lee, Yangho; Kim, Young Kyung; Park, Chan Ho; Kwon, Tae-Yub | Kyungpook Natl Univ, Grad Sch, Dept Med & Biol Engn, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Conservat Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Dent Biomat, Daegu 41940, South Korea; Kyungpook Natl Univ, Inst Biomat Res & Dev, Daegu 41940, South Korea | JOURNAL OF NANOSCIENCE AND NANOTECHNOLOGY | 1533-4880 | 1533-4899 | 20 | 9 | 0 | Zirconia Ceramic; Primer; Zirconia Powder; Shear Bond Strength | English | 2020 | 2020-09 | 10.1166/jnn.2020.17617 | 바로가기 | 바로가기 | |||||||||||||||||||
| ○ | Article | Effect of nitrate, ammonium and phosphate on the growth and microcystin production of Korean Microcystis species | Aim: This study aimed to investigate the effects of nitrogen (NO3-N, NH3-N) and phosphorus (PO4-P) on the growth and microcystin production of two bloom-forming Microcystis species (toxic M. aeruginosa MAHC160824 and non-toxic M. viridis MVHC160824). Methodology: The two Microcystis species were isolated from the lower reaches of the Nakdong River, South Korea. In the culture experiments, the average nutrient concentrations (NH3-N, NO3-N and PO4-P) at which Microcystis appeared (> 15 degrees C) was used as control medium. Different concentrations of NH3-N, NO3-N and PO4-P were then employed in nutrient testing (control, vs. 4 times and 16 times higher than the control). Microcystin levels were measured using a UPLC (TM) (LC MS/MS) system. Results: Both toxic and non-toxic Microcystis strains exhibited a maximum cell density at 30 degrees C and a maximum growth rate at 25-30 degrees C. In the nutrient addition assays, the maximum growth of two Microcystis species were found at nutrient concentrations 4 to 16 times higher than the control (NH3-N: 0.468 mg l(-1), PO4-P: 0.100 mg l(-1), NO3-N: 32.5 mg l(-1)). The highest microcystin production levels were found under optimal growth conditions. The microcystin levels of toxic M. aeruginosa MAHC160824 were below the detection limit despite a higher number of cells (> 300,000 cells ml(-1)) at the same nutrients concentrations as those found in raw water from the Nakdong River. Interpretation: Higher production of microcystin occurs when there is an increase in NH3-N and PO4-P within a restricted range in toxic species M. aeruginosa MAHC160824, else the production is low. | Lee, J.

| ○ | ○ | Article | Effect of Prognosis Awareness on the Survival and Quality of Life of Terminally Ill Cancer Patients: A Prospective Cohort Study | Background: Physicians and caregivers are conflicted over whether to inform patients that their disease is terminal. Studies examining the effect of awareness of prognosis on the survival and quality of life of terminally ill cancer patients report conflicting results. This study aimed to assess the effects of prognosis awareness on the survival time and psychological health of terminally ill cancer patients. Methods: Patients in the hospice wards of two general hospitals were asked to complete a questionnaire. All were mentally alert and could express themselves clearly. Awareness of prognosis was defined as knowing both the diagnosis and exact prognosis. Survival time was defined as the time from hospital admission to death. Multiple psychological examinations were conducted to verify the effect of prognosis awareness on psychological health. Results: Of the 98 subjects who met the inclusion criteria, 65 (66.3%) were aware of their terminal status. The patients' awareness was significantly related to survival time after adjusting for clinical variables with a hazard ratio of 1.70 (95% confidence interval [CI], 1.01-2.86). Furthermore, the unaware group had a higher risk of cognitive impairment (Mini-Mental State Examination <24; adjusted odds ratio [aOR], 3.65; 95% CI, 1.26-10.59) and a poorer quality of life (physical component summary of the Short Form 36-item Health Survey <20; aOR, 3.61; 95% CI, 1.1211.60) than the aware group. Conclusion: Knowledge of the exact prognosis might have a positive effect on the survival and quality of life of terminally ill cancer patients. | Lee, Hanna; Ko, Hae-Jin; Kim, A-Sol; Kim, Sung-Min; Moon, Hana; Choi, Hye-In | Kyungpook Natl Univ, Sch Med, Dept Family Med, Daegu, South Korea; Kyungpook Natl Univ Hosp, Dept Family Med, Daegu, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Family Med, Daegu, South Korea | 58402037600; 54393415700; 57203290656; 57216656403; 57188814366; 57202001023 | liveforme@knu.ac.kr; | KOREAN JOURNAL OF FAMILY MEDICINE | KOREAN J FAM MED | 2092-6715 | 41 | 2 | ESCI | PRIMARY HEALTH CARE | 2020 | N/A | 1.28 | 2025-06-25 | 13 | 11 | Awareness; Hospices; Life Expectancy; Prognosis; Quality of Life | INFORMATION NEEDS; PALLIATIVE CARE; DISCLOSURE; CHEMOTHERAPY; INVENTORY; MANAGEMENT; DIAGNOSIS; PHYSICIAN; ATTITUDES; ILLNESS | Awareness; Hospices; Life expectancy; Prognosis; Quality of life | English | 2020 | 2020-03 | 10.4082/kjfm.18.0113 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Effect of soil water and shading treatment on chlorophyll fluorescence parameters and photosynthetic capacity in cnidium officinale makino | Background: Measurement of chlorophyll fluorescence (CF) is useful for detection the ability of plants to tolerate environmental stresses such as drought, and excessive sunlight. Cnidium offici-nale Makino is highly sensitive to water stress and excessive sunlight. In this study, we evaluated the effect of soil water and shade treatment on the photosynthesis and leaf temperature change of C. officinale. Methods and Results: C. officinale was cultivated under uniform irrigation for 1 week drought stress (no watering) for 6 days. A significant decrease in CF was observed on the 5th day of with-holding water (approximately 6% of soil water content) regardless of shading. Notably, the Rfdₗₛₛ parameter (CF decrease rates) with and without shade treatment was reduced by 73.1% and 56.5% respectively, at 6 days compared with those at the initial stage (0 day). The patterns of the degree of CF parameters corresponded to those of the soil water content and difference between leaf temperature (Ts) and air temperature (Ta). Meanwhile, CF parameters recovered to the 3-4 days levels after re-watering, while the soil water potential was completely restored. The suitable soil water content for C. officinale optimal growth was between-5 ㎪ and-10 ㎪ in this experiment. Conclusions: Lack of soil water in the cultivation of C. officinale, even with shading, decreased latent heat cooling through transpiration. As a result, heat dissipation declined, and the plant was subjected to drought stress. Soil water content plays a major role in photosynthesis and leaf temperature in C. officinale. © 2020, Korean Society of Medicinal Crop Science.

| ○ | ○ | Article | Effect of transpiration on the physiological vitality of Zelkova serrata | This study aimed to investigate the effect of suppressing transpiration on the physiological characteristics of trees and identify suitable indicators to assess tree vitality. Three seedlings of Zelkova serrata were used: a control, a unit treated on the upper sides of the leaves (TU), and a unit treated on double sides of the leaves (TD). Changes in photosynthetic rate, transpiration rate, sap velocity, and bark temperature following the suppression of transpiration were measured. The transpiration rate and other physiological characteristics of TU were not significantly different from those of the control except for photosynthetic rate. However, TD showed a significantly lower photosynthetic rate, transpiration rate, and sap velocity compared to the control. The bark temperature of TD was not significantly higher than that of the control and TU. Our findings indicate that photosynthetic rate and sap velocity were positively correlated with transpiration rate, whereas bark temperature was negatively correlated. Furthermore, photosynthetic rate showed the most significant linear relationship with transpiration rate, suggesting the photosynthetic rate is a suitable physiological indicator to evaluate the vitality of Z. serrata. | Kim, Dong-Hak; Jung, Ji-Young; Lee, Cheul-Ho; Park, Byung-Duck; Bae, Kwan-Ho; Kim, Ki Woo; Kim, Pan-Gi | Kyungpook Natl Univ, Dept Ecol & Environm Syst, Sangju, South Korea; Korea Natl Arboretum, DMZ Bot Garden, Yanggu 24564, South Korea; Kyungpook Natl Univ, Sch Automot Engn, Sangju, South Korea | Kim, Ki Woo/AAC-5623-2022 | 57218438031; 57218437735; 57189294762; 57217586474; 35108758200; 57201369889; 7402334604 | chlee63@korea.kr; | FOREST SCIENCE AND TECHNOLOGY | FOR SCI TECHNOL | 2158-0103 | 2158-0715 | 16 | 3 | ESCI | FORESTRY | 2020 | N/A | 0.18 | 2025-06-25 | 3 | 3 | Bark temperature; photosynthetic rate; sap velocity; stomatal conductance; transpiration rate; vitality | SAP FLOW; STOMATAL CONDUCTANCE; FOREST | Bark temperature; photosynthetic rate; sap velocity; stomatal conductance; transpiration rate; vitality | English | 2020 | 2020 | 10.1080/21580103.2020.1801525 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Effect of water hardness on coffee composition and coffee preference by university students | Water is a major ingredient and comprises over 98% content of coffee. In this study, coffees prepared with distilled water (L) and waters with medium (M) and high hardness (H) were investigated for organic acid, caffeine, and eugenol contents and analyzed by sensory evaluation. Organic acid content was the highest in H-coffee. The contents of chlorogenic acid and caffeine, the characteristic bitter taste molecules, were the highest in L-coffee. The level of eugenol, one of the representative aroma components, was the lowest in M-coffee but similar between L- A nd H-coffees. The sensory evaluation test, conducted on a university student group comprising 56 female and 47 male participants, showed that L-coffee was the most preferred (42% or higher), but there was no significant difference in bitterness, acidity, body, and balance. Results suggest that the preference index of coffee taste among university students may be different from that of coffee experts who prefer coffee extracted with water of certain hardness. © 2020 Korean Society of Food Science and Technology.

| ○ | Article | Effectiveness of tongue crib combination treating severe skeletal angle class III malocclusion in mixed dentition | Objective: To evaluate the treatment effects of tongue crib combination for treating severe skeletal Angle class III malocclusion in mixed dentition by X-ray cephalometric analysis. Materials and methods: A sample of 22 patients with severe skeletal Angle class III malocclusion of deficiency maxilla and overgrown mandible in mixed dentition was prospectively collected and equally divided into two groups. The patients (males 6 and females 5; mean age 8.35 ± 1.6 years) in the study group were treated with tongue crib combination, and the untreated patients (females 5, males 6; mean age 8.12 ± 1.3 years) served as the control group. X-ray cephalometric films were measured before and after treatment for comparing the change of occlusion, maxilla, mandible, and soft tissue. A paired t-test was used by SPSS 21.0 statistical software. The intragroup data were compared by using the Wilcoxon test, and intergroup data were compared by using the Mann–Whitney U test (p < 0.05). Results: In the study group, all patients got a favorable facial profile. Anterior and posterior teeth crossbite and upper and lower first molars relationships were improved. In cephalometric measurement, significant changes were noted in the maxillary skeletal component. The significant forward growth of the maxilla exhibited in a statistical increase of SNA, ANS-PNS, Wits appraisal, p < 0.05. The mandible revealed slightly posterior rotation by no significant decrease in SNB and no change Co-Gn. After 1-year of retention, the changes of the teeth showed self-correction and facial profile improved further. Regarding vertical changes, maintenance of growth was shown a small non-significant increase of FMA, N-Me, and ANS-Me. There is a significant difference from those in the control group (p < 0.05). Conclusion: Tongue crib combination is an effective device for the patients in the growing period with skeletal Angle class III malocclusion by improving the maxillary growth and limiting the mandibular growth. © Jaypee Brothers Medical Publishers. | Zhao, Wenting; Chen, Yan; Kyung, Hee-Moon; Xu, Jin-Shuai | Department of Orthodontics, School of Dentistry, Kyungpook National University, Daegu, South Korea; Department of Orthodontics, Affiliated Hospital of Inner Mongolia Medical College, Hohhot, Inner Mongolia, China; Department of Orthodontics, School of Dentistry, Kyungpook National University, Daegu, South Korea; Oral Department, General Hospital of Datong Coal Mine, Datong, Shanxi, China | 56283218700; 57222905128; 7004292284; 57222899363 | 1336806259@qq.com; | International Journal of Clinical Pediatric Dentistry | 0974-7052 | 13 | 6 | 0.28 | 2025-06-25 | 2 | Growing period; Skeletal Angle class III malocclusion; Tongue crib combination; X-ray cephalometric analysis | English | Final | 2020 | 10.5005/jp-journals-10005-1855 | 바로가기 | 바로가기 | ||||||||||||||||

| ○ | Article | Effects of clinical practice stress and moral sensitivity on clinical competency in nursing students | Purpose: This study was conducted to explore how clinical practice stress and moral sensitivity affect the clinical competency of nursing students. Methods: Participants had completed at least a one year (2 semesters) clinical nursing practicum through K University in D Metropolitan City. A total of 188 nursing students were recruited: third grade (n=104) and fourth grade (n=84). The questionnaires were adopted with clinical practice stress, Korean version of moral sensitivity questionnaire (K-MSQ), and the clinical competency. Results: Clinical competency was positively correlated with patient-oriented care (r=.27, p<.001) and the professional responsibility (r=.32, p<.001) of the moral sensitivity (r=.27, p<.001). The attitude of medical personnel experiencing clinical practice stress shows a significant positive relationship with clinical competency (r=.15, p=.038). The attitude of medical personnel (ß=.09, p=.194) experiencing clinical practice stress, patient-oriented care (ß=.16, p=.041) and professional responsibility (ß=.23, p=.003) of the moral sensitivity explained 12% of the variance in clinical competency (F=9.17, p<.001). Therefore, the influential factors on clinical competency were two sub-factors of moral sensitivity. Conclusion: Moral educational programs should be considered to develop a nursing students' clinical competency. © 2020, Official of Journal of Korean Academic Society of Nursing Education.
