This study presents a descriptive statistical analysis on grade characteristics and employment rates of three ocean-related departments at a university. The ocean-related departments belong to the same college along with the other six departments. To obtain the correlation between the grade characteristics and employment rates, we carried out the followings. Firstly, four-year employment rates and six-semester GPAs (grade point averages) were obtained from the nine departments. Secondly, the box-and-whisker plots were constructed for each data set to capture the grade characteristics (mean, the first quartile, median, third quartile, whisker+, and Q3 box). Finally, the grade characteristics and employment rates were correlated. It is shown from the correlation analysis that the employment rate has a positive linear relation with the mean or third quartile, while the rate has a negative linear relation with the whisker+ or Q3 box, for the ocean-related departments possibly because these departments have higher regular employment rates than those of the other six departments.

Purpose: This study was done to determine inpatient fall rates in an acute hospital setting and to explore risk factors and characteristics across clinical departments. Methods: The medical records and standardized fall reports of 416 patients admitted between January 1 and December 31, 2012 were reviewed. Descriptive statistics and statistical tests were used, including: t-test, ${\chi}^2$-test, ANOVA. Results: The total fall rate per 1,000 inpatient days was 0.49. Fall rate, fall risk factors and characteristics such as age, type of fallers and mean MFS (Morse Fall Scale) differed significantly among clinical departments. Conclusions: The analysis results show that the fall rates, fall risk factors and characteristics of acute hospital inpatient falls varied significantly across clinical departments. The findings of this study suggest that hospitals should consider differences in fall related characteristics across clinical departments when implementation fall prevention strategies and interventions.

The length of stay in emergency departments has been used as a quality indicator to reflect the overall efficiency of emergency care. Identifying characteristics associated with length of stay is critical to monitor overcrowding and improve efficient throughput function of emergency departments. This study examined the level of waiting time for initial assessment by physician and length of stay in emergency departments. Furthermore, we investigated the characteristics of patients' attendance associated with length of stay. An observational study was performed for a sample of 1,526 patients visiting ten nation-wide emergency departments. A structured form was designed to collect information about patients' demographics, route of admission, time and mode of arrival, triage level, cause of attendance, initial assessment time by physician, departure time, and disposition. Multiple regression analysis was performed to determine factors associated with length of stay. The average length of stay was 209.4 minutes (95% confidence interval [CI]=197.1-221.7), with a mean waiting time for initial assessment of 5.9 minutes (95% CI=5.1-6.7). After controlling for emergency department characteristics, increasing age, longer waiting times, attendance due to diseases, higher acuity, multiple diagnoses($\geq$2) and requiring admission or transfer to other health care facilities were positively associated with length of stay in emergency departments. The findings suggest that both patients' characteristics and the flow between emergency departments and parent hospitals should be taken into account in predicting length of stay in emergency departments.

Objective : The authors have speculated that metastatic brain lesions from renal cell carcinoma (RCC) show diverse radiological patterns and tumor responses after Gamma knife surgery (GKS), and have hypothesized that these can be predicted from tumor radiological characteristics. The goal of the current study was to identify the radiological characteristics of RCC brain metastases and the predictors of initial radiosurgical response after GKS. Methods : A retrospective analysis was performed on 48 lesions in 18 patients with RCC brain metastasis treated by GKS. The radiological characteristics of these lesions in magnetic resonance images (MRI) were classified into 3 categories according to enhancement patterns in T1-weighted images and signal intensity characteristics in T2-weighted images. Responses to GKS were analyzed according to these categories, and in addition, other potential predictive factors were also evaluated. Results : MRI findings in the three categories were diverse, though numbers of the lesion were comparable. At 2-month MRI follow-ups after GKS, response rate was 54% and the local tumor control rate 83%. T2 signal intensity was found to be the principal predictive factor of response to GKS, namely negative predictive factor. Other variables such as age, sex, tumor volume, dose, duration from initial diagnosis to GKS, and previous systemic therapies failed to show significant relationships with treatment response by multivariate analysis. Conclusion : Careful evaluation of the radiological characteristics of brain metastases from RCC is important prior to GKS because MRI heterogeneity has predictive value in terms of determining initial tumor response.

The cervical spine plays a critical role in supporting the skull, maintaining horizontal gaze, and facilitating walking. Its unique characteristics, including the widest range of motion among spinal segments, have led to extensive research on cervical sagittal alignment. Various parameters have been proposed to evaluate cervical alignment, with studies investigating their clinical significance, correlation with symptoms, and implications for surgical interventions. Recent findings suggest that cervical sagittal alignment not only impacts the cervical spine but also influences global spine-pelvic alignment through compensatory mechanisms. This comprehensive review examines classical and new parameters of cervical sagittal alignment and considers the dynamic and muscular factors associated with it.

Instrumentation and technologies are described for determining the vibration response characteristics of the pear with frequency range 5 to 320Hz. The computer program for controlling the vibration exciter and the function generator and for measuring the vibration response characteristics of the pear was developed. Mechanical properties such bioyield deformation, rupture deformation and apparent elastic modulus etc. were compared with the vibration response characteristics of the pear. The resonant frequency of the pear ranged from 53 to 102Hz and the amplitude at resonance was between 1.08 and 2.48g-rms. The resonant frequency and amplitude at resonance decreased with the increase of the sample mass, and they were slightly affected by mechanical properties such as bioyield deformation and rupture deformation. Regression analysis was performed among the relatively high correlated parameters from the results of correlation coefficient analysis.

This study aims to compare the current conditions of fashion education organizations in Korea and China. The results are as follows: 1. As for the departments related to fashion in Korea, the department of clothing was most frequently found in the fields of everyday science and natural science and design was most frequent in art related fields. 2. As for the departments related to fashion in China, the department of design was usually found in the fields of spinning and weaving, art, fashion, and others, and a college was dedicated to is having departments related to the fashion industry, much larger in scale compare to Korea. 3. Subject analysis found that both Korea and China put the most weight on the subject of design than any other fields. 4. Subject analysis of the fashion related departments in Korea found that all three department groups put considerable weight on clothing design and clothing composition subjects with other subjects having greater parts in the curriculum. 5. As for the departments related to fashion in China, design-related subjects were most frequently found, irrespective of the title of the fashion department, and the subjects concerning fashion marketing were widely distributed. 6. It seems that the curriculum for fashion colleges in China have been affected by the characteristics of the university before absorptive integration and setting based on the local characteristics rather than by the characteristics of the college. 7. For the curriculum of Korea, it is necessary to divide theoretical and practical ones and to develop practical subjects in association with experts in actual fields. China needs to take into account the local characteristics due to its global curriculum and large area.

Poststreptococcal glomerulonephritis (PSGN) is one of the most well-known and important infectious renal diseases resulting from a prior infection with group A ${\beta}$-hemolytic streptococcus. The typical clinical characteristics of the disease reflect acute onset with gross hematuria, edema, hypertension and moderate proteinuria after the antecedent streptococcal infection. In children, usually PSGN is healed spontaneously but if it combines with fast progressing glomerulonephritis, it would be developed to chronic renal failure. Therefore, it is important to make a fast diagnosis and treatment by simple tools to predict the course and the prognosis of disease. Sonography is a simple tool for diagnosis but there is no typical renal sonographic finding in PSGN, so it is difficult to predict the course and the prognosis of disease by sonographic findings. In comparison between two cases of renal sonographic findings in PSGN, a patient who showed more increased echogenicity in more extended area of renal sonography had the severe results of renal pathology, prolonged treatment period and low serum C3 level. Here, we report the different findings of renal sonography and pathology depending on the degree of severity between two patients. Thus, it is necessary to gather more information from further studies to make a consensus about the relationship between the renal sonography and the prognosis of disease in PSGN.
