Background: The aim of this study is to determine the correlation between clinical assessment scales, self-assessment scales, and surface electromyography (SEMG) for facial nerve palsy. Methods: This study assessed 32 cases of facial nerve palsy on the first visit, 11 cases on the second visit, and 9 cases on the third visit to the Korean medicine hospital, university. This study was conducted from October 22, 2022, to December 22, 2022. The patients were evaluated using SEMG, clinical assessment scales, and self-assessment scales 3 times. The House-Brackmann grading systems (HBGS), Yanagihara unweighted grading system (Y-score), facial disability index, numerous rating scale, and accompanying symptoms of facial nerve palsy were used for assessment. Moreover, statistical correlation was analyzed using Pearson correlation. Results: On Visit 1, Significant correlations were observed between the results of SEMG and other clinical assessment scales as well as between SEMG-F (frontalis) and different parts of the Y-score. On Visit 2, significant correlations were observed between the results of SEMG and HBGS as well as between SEMG-F and the detailed parts of the Y-score. On Visit 3, significant correlations were observed only between SEMG-F and the detailed parts of the Y-score. A significant correlation was also observed between the changes in the clinical assessment scales on Visits 1 and 3 and between the changes in SEMG-F and those in the patient self-assessment scales. Conclusion: These findings suggest that SEMG can be used to evaluate facial nerve palsy in conjunction with the use of other clinical assessment scales.

Purpose : The purpose of this study was to investigate health college students' awareness and knowledge of the dementia policy and their attitudes toward dementia. Methods : In this study, 294 questionnaires were collected from 301 college students in the Department of Health of K College in Busan from November 7 to 29, 2022. The questionnaire consisted of 59 items, including 9 items on general characteristics, 10 on awareness of the dementia policy, 15 on attitudes toward dementia, and 25 on knowledge about dementia. The collected data were analyzed using descriptive statistics, independent t test, and one-way analysis of variance with SPSS version 25. A post-analysis was performed using the Scheffe test. Dementia policy awareness, knowledge of dementia, and attitude toward dementia were analyzed with the Pearson correlation coefficient by factor. Results : The health students' dementia policy awareness and knowledge of dementia were high, and their attitudes toward dementia were positive. High knowledge of dementia was influenced by sex, interest in dementia, presence of dementia information, and related volunteer work experience. Positive attitudes toward dementia were related to sex, department, and mode of receiving dementia information. High dementia policy perceptions were associated with interest in dementia and the presence or absence of information on dementia. Positive correlations were found between dementia policy perception and knowledge and attitude toward dementia. Conclusion : According to our study, interest in dementia is increasing owing to the recent dementia safety system. As a result, the dementia policy awareness and knowledge of dementia among college students pursuing health studies were high, and their attitude toward dementia was positive. From these results, we can infer that systematic and continuous education on dementia should be conducted in universities.

Objective: This study aimed 1) to compare the Landing Error Scoring System (LESS) score and movement patterns during landing of the lesser dorsiflexion range of motion (LDFROM) group to that with the greater dorsiflexion range of motion group, and 2) to identify the correlation between the weight-bearing dorsiflexion range of motion (WBDF ROM), LESS score, and movement patterns during landing. Method: Fifty health adults participated in this study. WBDF ROM was measured using the weight bearing lunge test while movement patterns during landing was assessed using the LESS. The joint angles of the ankle, knee and hip joints during landing were analyzed using the 2D video analysis. After mean value of WBDF ROM was calculated, participants were divided into two groups (GDFROM and LDFROM) based on the mean value. The Mann-Whiteny 𝒰 test was used to identify differences in movement strategies during landing between two groups and the Pearson's correlation analysis was performed to determine relationships between WBDF ROM and movement strategies. Results: The LDFROM group showed the poorer LESS score and stiffer landing kinematics during landing compared to the GDFROM group (p<0.05). In addition, DFROM was significantly related to the LESS score and landing kinematics (p<0.05) except for total hip excursion (p=0.228). Conclusion: Our main findings showed that the LDFROM group had poorer landing quality and stiffer landing movements compared to the GDFROM group. In addition, increase of WBDF ROM significantly improved landing quality and soft-landing movements. To reduce shock during landing such as ground reaction forces, individuals need to better utilize WBDF ROM and lower extremity movements based on our findings. Therefore, intervention programs for safer landings should include exercises that increase WBDF ROM and utilize eccentric contraction.

The autonomic regulation of heart rate (HR) is an indicator of the body's ability to adapt to an exercise stimulus. However, there are no reports on this topic in relation to Jeju horses used for racing. The aim of this study was to analyze the HR responses of Jeju horses during race trials and to investigate the correlation between HR and performance in these horses. HR data were collected from 17 healthy 2- to 7-year-old Jeju horses wearing HR monitors during race trials. Pearson correlation coefficients was used to determine the significance of the association between the race trial time and HR. A significant inverse correlation was observed between the race trial time (performance) and both the maximal HR (HRmax, r = -0.69, p < 0.01) and HR reserve (HRR) (HRmax - average HR during the warm-up period, r = -0.63, p < 0.01) and between the HRR and HRmax (r = 0.73, p < 0.01). Horses with a lower average HR during the warm-up period and higher heart rates during the trial achieved faster race trial times. This study reports the first HR measurements in Jeju horses during race trials, providing new insights into the HR response of this breed to exercise. The use of a noninvasive remote HR monitor system allowed assessment of exercise responses in the field, and the results suggest that both the HRR during warm-up period and HRmax may be useful performance indicators in Jeju horses.

Climate change has a broad impact on the entire water environment, and this impact is growing. Climate adaptation in water supply systems often involves quantity and quality control, but there has been a lack of research examining the impacts of climatic factors on water supply productivity and operation conditions. Therefore, the present study focused on, first, building a database of climatic factors and water purification operating conditions, and then identifying the correlations between factors to reveal their impacts. News big data was analyzed with keywords of climatic factors and water supply systems in either nationwide or region-wide analyses. Metropolitan area exhibited more issues with cold waves whereas there were more issues with drought in the Southern Chungcheong area. A survey was conducted to seek experts' opinions on the climatic impacts leading to these effects. Pre-chlorination due to drought, high-turbidity of intake water due to rainfall, an increase of toxins in intake water due to heat waves, and low water temperature due to cold waves were expected. Pearson correlation analysis was conducted based on meteorological data and the operating data of a water purification plant. Heavy rain resulted in 13 days of high turbidity, and the subsequent low turbidity conditions required 3 days of high coagulant dosage. This insight is expected to help inform the design of operation manuals for waterworks in response to climate change.

Purposes: Caregivers are placed in a poor working environment because there is no special legal basis or definition in the current medical system, and they have difficulty in supplying manpower due to frequent job change and retirement. Therefore, this study aimed to find out the effect on job consciousness, job stress, job satisfaction, and turnover intention of caregivers in nursing hospitals for the elderly. Methodology: In this study, a survey was conducted from May 2nd to 16th, 2022, targeting caregivers with more than 6 months of work experience working at 10 nursing hospitals in D City. Data were collected through convenience sampling, and a self-administered questionnaire method was used, in which subjects filled out a questionnaire. A total of 240 questionnaires were distributed, and 220 copies were considered for the final analysis after excluding non-response or inappropriate questionnaires for data use. Data analysis used t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression analysis, and the main results are as follows. Findings: Job stress and job satisfaction showed a significant correlation with the level of turnover intention, and were also found to be major determinants. On the other hand, among the occupational characteristics of the study subjects, employment type, job motivation, service period, number of patients, injury experience, and license status showed a significant difference from turnover intention. Conclusion: As a result of the above research, in order to prevent job turnover and retirement by improving job stress and job satisfaction of caregivers engaged in nursing hospitals, it is necessary not only to legalize caregivers, but also to secure an appropriate level of caregivers for nursing hospitals and improve specific treatment for caregivers. Ultimately, a policy alternative that can provide quality nursing service is required.

Objectives: This study investigated the prevalence and characteristics of comorbid conditions in patients exposed to ionizing radiation and those who were involved in the Soviet-Afghan war. Methods: This study analyzed the frequency and spectrum of morbidity and comorbidity in patients over a long-term period (30-35 years) following exposure to ionizing radiation at the Semipalatinsk nuclear test site or the Chornobyl nuclear power plant, and among participants of the Soviet-Afghan war. A cohort study, both prospective and retrospective, was conducted on 675 patients who underwent comprehensive examinations. Results: Numerical data were analyzed using the Statistica 6 program. The results are presented as the mean±standard deviation, median, and interquartile range (25-75th percentiles). The statistical significance of between-group differences was assessed using the Student t-test and Pearson chi-square test. A p-value of less than 0.05 was considered statistically significant. We found a high prevalence of cardiovascular diseases, including hypertension (55.0%) and cardiac ischemia (32.9%); these rates exceeded the average for this age group in the general population. Conclusions: The cumulative impact of causal occupational, environmental, and ultra-high stress factors in the combat zone in participants of the Soviet-Afghan war, along with common conventional factors, contributed to the formation of a specific comorbidity structure. This necessitates a rational approach to identifying early predictors of cardiovascular events and central nervous system disorders, as well as pathognomonic clinical symptoms in this patient cohort. It also underscores the importance of selecting suitable methods and strategies for implementing treatment and prevention measures.

Slope stability analysis and prediction are of critical importance to geotechnical engineers, given the severe consequences associated with slope failure. This research endeavors to forecast the factor of safety (FOS) for slopes through the implementation of six distinct ML techniques, including back propagation neural networks (BPNN), feed-forward neural networks (FFNN), Takagi-Sugeno fuzzy system (TSF), gene expression programming (GEP), and least-square support vector machine (Ls-SVM). 344 slope cases were analyzed, incorporating a variety of geometric and shear strength parameters measured through the PLAXIS software alongside several loss functions to assess the models' performance. The findings demonstrated that all models produced satisfactory results, with BPNN and GEP models proving to be the most precise, achieving an R² of 0.86 each and MAE and MAPE rates of 0.00012 and 0.00002 and 0.005 and 0.004, respectively. A Pearson correlation and residuals statistical analysis were carried out to examine the importance of each factor in the prediction, revealing that all considered geomechanical features are significantly relevant to slope stability. However, the parameters of friction angle and slope height were found to be the most and least significant, respectively. In addition, to aid in the FOS computation for engineering challenges, a graphical user interface (GUI) for the ML-based techniques was created.

Objective: This study investigates the influence of femoral and knee torsion angles on toe in-out orientation in adults. Design: Cross-sectional study design. Methods: We measured the passive internal and external rotation range of motion (ROM) of the hip and knee joints in 21 participants using a goniometer. Toe in-out orientation was assessed with the GaitRite gait analysis system during slow and fast walking trials over a 6-meter walkway. Pearson correlation analysis was used to examine the relationship between joint ROM and gait angle at both walking speeds. Intra- and inter-rater reliability were assessed, and simple linear regression was conducted to explore these relationships. Results: Intra-rater reliability demonstrated high reliability (0.84<ICC<0.94), while inter-rater reliability (0.44<ICC<0.83) exhibited moderate to high reliability. Significant correlations were found between the hip joint's range of motion and the gait angle at slow walking speed. Similar results were observed at fast walking speed for the hip joint. Multiple regression analysis revealed that the neutral angle of the hip joint (β=0.660, p<0.001) and the neutral angle of the knee joint (β=0.284, p=0.034) significantly contributed to the toe-out angle. Conclusions: Our findings indicate a significant correlation between the range of motion of the hip joint and toe in-out orientation. A decrease in the hip joint internal rotation angle was associated with a decrease in toe in-out, while an increase in the mid-angle was associated with an increase in toe in-out.
