Purpose: The purpose of this study was to identify factors influencing nursing performance of clinical nurses. Methods: This was a descriptive study involving 172 nurses who worked for 6 months or longer at one general hospital in B City. The data analysis was conducted with t-test, ANOVA, Scheffé test, Pearson's correlation coefficients, and stepwise multiple regression. Results: Nursing performance of participants positively correlated with job stress (r=.16, p=.033). The factors affecting nursing performance were total clinical experience (β=.37 p<.001), salary (β=.19, p=.028), and job stress (β=.13, p=.045). These variables had a 27.2% variance to explain nursing performance. Conclusion: Based on these results, administrative and financial support are required for the development of a clinical career program, including the differentiation of salary systems of clinical nurses. There is also a need to develop and implement job stress management and coping programs.

Purpose: The purpose of this study was to examine the relationships of knowledge, attitudes, and self-efficacy related to palliative care among health care providers (doctors and nurses) in order to provide a basis to develop a training program for health care providers. Methods: A correlational and descriptive study design was used. Participants were recruited from a university-affiliated hospital located in Daejeon and an e-nurse community. After IRB approval, data were collected from July 12, 2018, to September 30, 2018. A total of 169 responses were finally analyzed using version SPSS 24. The data were analyzed in terms of descriptive statistics (frequency and percentage or mean and standard deviation, as appropriate), the t-test, analysis of variance (with the Duncan post hoc test), and Pearson correlation coefficients. Results: Knowledge, attitudes, and self-efficacy were significantly higher in those who had received palliative care training or had been exposed to awareness-raising initiatives. There were positive relationships among knowledge, attitudes, and self-efficacy, with small to moderate effect sizes. Conclusion: Palliative care training for health care professionals is necessary to meet patients' needs. Such programs should take into account not only knowledge about palliative care, but also ways to improve empathy and resolve ethical dilemmas. Interprofessional training would be an excellent option to share therapeutic goals and develop communication skills among multidisciplinary team members.

In general, grinding is one of the final machining processes which determines the surface quality of machined products. Since the ground surface is affected by the states of grains and voids on the grinding wheel surface, the wheel should be dressed before the machined surface deteriorates over a quality limit This paper describes a systematic approach to decide a proper dressing chance and an optimal dressing depth for the working grinding wheel. An eddy current sensor and a laser displacement sensor are used to measure the loading on the working wheel surface and the topography of the dressed wheel surface respec- tively. The dressing chance can be properly decided through the relational locus between the amount of handing and the machined surface roughness. An optimal dressing depth to guarantee the less wheel loss and the higher wheel surface quality is decided through the analysis of the variance of topography for the dressed wheel surface, which decreases at three different rates according to the accumulated dressing depth.

Background: This study examined the effects of the bridge exercise with trunk rotation on the thickness of body trunk muscles, including external oblique, internal oblique, and transverse abdominis in healthy male adults. Design: Randomized controlled trial Methods: Twenty-four men were evenly divided into a trunk rotation bridge exercise group and a basic bridge exercise group by drawing lots. The two groups performed the respective exercise for thirty minutes, three times a week for six weeks. repeated measure analysis of variance (ANOVA) was used after distinguishing between three different time points before the experiment, three weeks after the experiment, and six weeks after the experiment. The significance level was set at 0.05. In case an interaction between time and group existed, the paired t-test was used to examine the within-group difference. The independent-sample t-test was used to check the between-group difference. The significance level was set at 0.05. Results: All the men showed a significant change over time in their external oblique, internal oblique, and transverse abdominis muscles. An interaction between time and group was also found (p<0.05). Conclusion: The bridge exercise with trunk rotation causes a meaningful difference in the thickness of external oblique, internal oblique, and transverse abdominis muscles. Therefore, this study proposes the use of this exercise for lower-back stabilization in future research and clinical settings.

Objective: Seasonal variations in semen quality are known to occur in temperate regions, but results regarding tropical areas remain inconclusive. The aim of this study was to determine whether monthly variations in semen parameters are present among men in a tropical region. Methods: Data were retrospectively collected from semen analyses of 3,000 men over a 10-year period, from 2012 to 2022. Analysis of variance and the independent-samples t-test were employed to observe variations in semen parameters throughout the entire period and between months, respectively. Results: The mean±standard deviation sperm concentration was significantly lower in June, at 42.5±31.4 million/mL, compared to other months. The highest sperm concentration was found in March, at 57.8±42.6 million/mL, constituting a mean difference of 15.3 million/mL between the lowest and highest concentrations. The total sperm count displayed a similar pattern of monthly variation, with a difference of 47.2 million between the highest and lowest months. No significant monthly differences were observed in other parameters, such as sperm motility, morphology, and semen volume. Conclusion: Significant monthly variations in sperm concentration and total sperm count were evident in this Sri Lankan population. March, which displayed the highest sperm counts, is in the spring in temperate regions, while the month with the lowest counts, July, is part of the summer. Fluctuations in photoperiod appear to most strongly influence these variations.

Objective: To determine the correlation between dentoskeletal parameters related to craniofacial morphology and the upper airway (UA) volume. Methods: Cone-beam computed tomography images of 106 randomly selected orthodontic patients were analyzed using NemoFab Ortho software. The dentoskeletal variables assessed were anterior facial height (AFH), posterior facial height (PFH), PFH/AFH ratio, hyoid position, maxillary width (MW), and palatal depth. The UA volume (evaluation in anatomical regions and as a whole) was also assessed using the same software. We also evaluated potential differences in UA variables between age and sex groups. The correlation between the dentoskeletal parameters and UA volume was calculated using the Pearson correlation coefficient (R). Analysis of variance and Student's t test were performed to assess differences between age and sex for UA variables. Statistical analyses were performed using SPSS software (version 26 for Windows). Results: This study found that PFH, AFH, and MW were the dentoskeletal parameters most strongly correlated with UA volume. However, the ANB angle did not show any significant correlation with UA volume. Additionally, differences in UA volumes were observed between age groups. Sex differences were found in both the "8-12" and "≥ 16" age groups for oropharyngeal and pharyngeal volumes. Conclusions: In conclusion, our findings indicate a significant correlation between UA volume and dentoskeletal parameters, particularly those related to facial height and MW.

This paper analyzes the in-service training program for the 1st grade English teacher in the following 7 regions: Taejeon, Seoul, Incheon, Kangwon, Kyeonggi, Chungnam and Chungbuk. It also investigates the actual conditions of the program. The analyses are performed on three categories of subjects: Teaching Profession, Refinement and English Education. The English Education category can be divided into the three aspects: language skills, communicative skills and language learning/teaching skills. Among the 7 regions, subjects under Teaching Profession, Refinement and English Education have a significant (2-3 times +/-) variance in terms of the number and credit hours of the courses. While the Refinement Program is above the standard set by Ministry of Education & Human Resources Development(MEHRD) in some regions, the Teaching Profession Program and the English Education Program is below the standard set by MEHRD in other regions. To overcome the weaknesses of the program, this paper suggests the following: 1) prescriptions for the proportion ratio of each category should be suitably modified. 2) MEHRD should observe and supervise the program of each region. 3) being organized, the program must have two parts as follows: the same mandatory subjects for all regions and optional subjects suited to each region.

This paper reports briefly on the computational results of a turbulent Rayleigh-Benard convection with the elliptic-blending second-moment closure (EBM). The primary emphasis of the study is placed on an investigation of accuracy and numerical stability of the elliptic-blending second-moment closure for the turbulent Rayleigh-Benard convection. The turbulent heat fluxes in this study are treated by the algebraic flux model with the temperature variance and molecular dissipation rate of turbulent heat flux. The model is applied to the prediction of the turbulent Rayleigh-Benard convection for Rayleigh numbers ranging from Ra=$2{\times}10^6$ to Ra=$10^9$ and the computed results are compared with the previous experimental correlations, T-RANS and LES results. The predicted cell-averaged Nusselt number follows the correlation by Peng et al.(2006) (Nu=$0.162Ra^{0.286}$) in the 'soft' convective turbulence region ($2{\times}10^6{\leq}Ra{\leq}4{\times}10^7$) and it follows the experimental correlation by Niemela et al. (2000) (N=$0.124Ra^{0.309}$) in the 'hard' convective turbulence region ($10^8{\leq}Ra{\leq}10^9$) within 5% accuracy. This results show that the elliptic-blending second-moment closure with an algebraic flux model predicts very accurately the Rayleigh-Benard convection.
