We investigated the process of yolk absorption in Korean rose bitterling, Rhodeus uyekii, and determined the changes in its morphometric characteristics. The R. uyekii from 1 days post hatching (DPH) to 21 DPH, the eye diameter (ED) was 5.4 at 5 DPH. Thereafter, the ED/total length (TL) ratio increased to 10.7 at 21 DPH (p<0.05). The yolk length (YL) decreased from 95.4 to 1.1 by 21 DPH, and this rate of decrease was greater than that for any other dimension (p<0.05). 12 morphometric dimensions/TL for the R. uyekii were measured at each sampling day from 21 DPH to 170 DPH. At just hatching, the average TL and BW were $6.1{\pm}0.09mm$ and $4.9{\pm}0.07mg$, respectively. At 53 DPH, the average TL was $12.9{\pm}0.28mm$ and the average BW was $14.7{\pm}0.72mg$; the total length growth equation was $TL=5.507e^{0.038t}$ ($R^2=0.916$). Further, the body weight growth equation was $BW=3.3647e^{0.0296t}$ ($R^2=0.9354$). The dimensions with regard to body depth showed the greatest growth rates in the external characteristics of the fish (p<0.05). The patterns of the morphometric characteristics measured in this study can be classified in three ways. The patterns were shown to be increased (y=0.0992x+12.07, $R^2=0.8333$), decreased (y=-0.0569x+42.029, $R^2=0.8395$) or maintained (y=0.005x+18.263, $R^2=0.3678$) from 21 DPH to 170. These results will provide useful indices for the successful rearing of the R. uyekii.

This study aimed to identify the factors influencing the clinical competence of nurses, using a descriptive correlational study design. Data were collected through questionnaires administered to 170 nurses working in a general hospital in Gwangju city and Jeollanam-do province from March 24 to May 27, 2021. There were significant differences in clinical competence according to age, marital status, and educational level. Clinical competence was significantly correlated with nursing professionalism (r=.600, p<.001), critical-thinking disposition (r=.568, p<.001), communication skills (r=.658, p<.001), and nursing practice environment (r=.353, p<.001). Factors influencing clinical competence were communication skills, nursing professionalism, critical-thinking disposition, and age, which explained 54.0% of the total variance. It is necessary to develop educational programs to improve the communication skills, nursing professionalism, and critical-thinking disposition of nurses. Additionally, Institutional and national measures are needed so that nurses can continue to work in hospitals.

Background: Measurement of insulin and C-peptide concentrations is important for deciding whether insulin treatment is required in diabetic patients. We aimed to investigate the analytical performance of insulin and C-peptide assays using the Lumipulse G1200 system (Fujirebio Inc., Tokyo, Japan). Methods: We examined the precision, linearity, and cross-reactivity of insulin and C-peptide using five insulin analogues and purified proinsulin. A method comparison was conducted between the Lumipulse G1200 and Roche E170 (Roche Diagnostics, Mannheim, Germany) systems in 200 diabetic patients on insulin treatment. Reference intervals for insulin and C-peptide concentrations were determined in 279 healthy individuals. Results: For insulin and C-peptide assays, within-laboratory precision (% CV) was 3.78-4.14 and 2.89-3.35%, respectively. The linearity of the insulin assay in the range of 0-2,778 pmol/L was $R^2=0.9997$, and that of the C-peptide assay in the range of 0-10 nmol/L was $R^2=0.9996$. The correlation coefficient (r) between the Roche E170 and Lumipulse G1200 results was 0.943 (P <0.001) for insulin and 0.996 (P <0.001) for C-peptide. The mean differences in insulin and C-peptide between Lumipulse G1200 and the Roche E170 were 19.4 pmol/L and 0.2 nmol/L, respectively. None of the insulin analogues or proinsulin showed significant cross-reactivity with the Lumipulse G1200. Reference intervals of insulin and C-peptide were 7.64-70.14 pmol/L and 0.17-0.85 nmol/L, respectively. Conclusions: Insulin and C-peptide tests on the Lumipulse G1200 show adequate analytical performance and are expected to be acceptable for use in clinical areas.

Purpose: This study was designed to assess the types of nursing organizational culture, and degree of self-leadership and burnout as perceived by perioperative nurses, and to identify correlations between these variables. Methods: Participants were 155 nurses from 3 tertiary hospitals in Seoul and data were analyzed using descriptive statistics, ANOVA, Scheffe, and Pearson correlation coefficient. Results: In the types of nursing organizational culture, the mean score for hierarchy-oriented culture was 3.57, and for self-leadership, 3.61 and for burnout, 2.87. In the relationship between the types of nursing organizational culture, self-leadership and burnout, relation-oriented culture (r=.24, p<.01), innovation-oriented culture (r=.23, p<.01) and task-oriented culture (r=.22, p<.01) had a slight positive correlation with self-leadership in that order. The innovation-oriented culture (r=-.29, p<.01) and relation-oriented culture (r=-.42, p<.01) among the types of nursing organizational culture showed a negative correlation with burnout while the hierarchy-oriented culture (r=.28, p<.01) showed a positive correlation with burnout. Self-leadership showed a negative correlation with burnout (r=-.42, p<.01). Conclusion: The results show that nurses in operating rooms have a high awareness of hierarchy-oriented culture that affects burnout in a negative way while having a low awareness of relation-oriented culture that has a positive influence on burnout.

We developed internal and external type sensor to measure ultra-high frequency (UHF) partial discharge (PD) in 170 kV gas-insulated switchgears (GIS). We also manufactured a PD-generator to verify and measure the detection sensitivity of those sensors. We measured the output power of the UHF PD sensors induced by PDs of 5 pC using the PD-generator. We measured UHF propagation loss of an 170 kV GIS for optimal arrangement of the sensors. We used swept UHF signal from a network analyzer into the GIS to measure the loss of various components of the GIS.

Herein, we report the first occurrence of web blight of rosemary caused by Rhizoctonia solani AG-1-IB in Gangneung, Gangwon Province, Korea, in August 2014. The leaf tissues of infected rosemary plants were blighted and white mycelial growth was seen on the stems. The fungus was isolated from diseased leaf tissue and cultured on potato dextrose agar for identification. The young hyphae had acute angular branching near the distal septum of the multinucleate cells and mature hyphal branches formed at an approximately $90^{\circ}$ angle. This is morphologically identical to R. solani AG-1-IB, as per previous reports. rDNA-ITS sequences of the fungus were homologous to those of R. solani AG-1-IB isolates in the GenBank database with a similarity percentage of 99%, thereby confirming the identity of the causative agent of the disease. Pathogenicity of the fungus in rosemary plants was also confirmed by Koch's postulates.

In order to assess the impact of proprioceptive exercises on the position sense ability of the knee joint, we conducted an analysis using Biodex System $3pro^{(R)}$, targeting 42 ordinary people (male=22, female=20). After applying proprioceptive exercise, we measured changes in balance and flexibility, and active articular position sense (AAPS), depending on gender. To find out the change in each measurement item variable, we carried out dependent t-tests. The statistical significance level was set to 0.05. The research showed that after applying the proprioceptive exercise, AAPS was significantly improved for both men and women (p<.01). In the case of women, the flexibility was significantly improved (p<.01). Also, the balance was significantly improved for both men and women (p<.01). Therefore, the proprioceptive exercise program is considered to be very useful in improving muscle and joint function, and preventing injuries. Thus, continuous clinical studies using Biodex system $3pro^{(R)}$ are required for a variety of scientific evaluations of proprioceptive skills.

Classification of radar signals in the field of electronic warfare is a problem of discriminating threat types by analyzing enemy threat radar signals such as aircraft, radar, and missile received through electronic warfare equipment. Recent radar systems have adopted a variety of modulation schemes that are different from those used in conventional systems, and are often difficult to analyze using existing algorithms. Also, it is necessary to design a robust algorithm for the signal received in the real environment due to the environmental influence and the measurement error due to the characteristics of the hardware. In this paper, we propose a radar signal classification method which are not affected by radar signal modulation methods and noise generation by using deep learning techniques.

Purpose: This descriptive study aimed to identify the contribution of nurses' communication styles, nurse-mother partnerships, and mothers' anxiety levels to the coping of mothers of hospitalized children, with the goal of establishing effective intervention strategies based on these factors. Methods: Data were collected using a structured questionnaire from July 12 to October 29, 2018. The study's participants were 200 hospitalized children's mothers in the pediatric ward of a university hospital. Results: The coping of hospitalized children's mothers showed a significant relationship with nurses' informative communication style (r=.26, p<.001), affective communication style (r=.28, p<.001), nurse-mother partnership (r=.50, p<.001), authoritative communication style (r=-.28, p<.001), and mothers' anxiety (r=-.23, p=.001). A multiple regression analysis (adjusted R²=.32) indicated that the factors affecting the mothers' coping included nurse-mother partnership (𝛽=.47, p<.001), another caregiver (yes) (𝛽=.17, p=.006), and mothers' subjective health status (very healthy) (𝛽=.15, p=.047). Conclusion: Considering that the formation of cooperative partnerships between mothers and nurses found in this study had a positive effect on the mothers' coping skills, it appears necessary to develop and implement programs for improving nurses' communication skills and ability to form partnerships, beginning from undergraduate education.
