Objective : This study was aimed to investigate the general features and differences between obesity and skinniness of patients with Bell's palsy. Methods : We measured the sex, age. BMI. pulse diagnosis and HBGS (House-Brackmann Grading System) of 234 patients who were diagnosed with Bell's palsy. Results and Conclusions : The results with statistical significance were as follows (1) The distribution of age revealed that 40s was the most at 30.8 %: (2) The improvement period in facial palsy patients with sub-paralysis was shorter than whole-paralysis. And in one part the more we treated, the shorter the improvement period was: (3) In distribution of fat rate in facial palsy patients, obesity was the most at 61.37%, low weight 15.88%. So we found that the fatter the patients was. the higher the onset rate was: (4) In distribution of pulse diagnosis in facial palsy patients with obesity. the ratio of Xu mai (虛脈) was 67.06%. Shi mai (實脈) 32.94%. The Xu mai was similar to Qi xu (氣虛). So we found that the facial palsy patients with obesity were more Qi xu than with low weight. In distribution of pulse diagnosis in facial palsy patients with skinniness, the ratio of Chi mai (遲脈) was none. Shuo mai (數脈) was most: (5) In distribution of region in facial palsy patients with obesity-Xu mai. the ratio of left was 45.10%, right 54.90%, but this result was not statistically significant.

Objectives : The purpose of this study is to evaluate the efficacy of acupuncture treatment on the inflammatory lesions and body image disturbances in patients with vulgaris acnes. Methods : Fifteen inflammatory acne patients were enrolled and treated with facial acupuncture during 4 treatment sessions. We evaluated the number of papules and nodules using the Korean Acne Grading System (KAGS). We also evaluated patients' general subjective satisfaction and objective changes of inflammatory acnes symptoms using DermaVision-pro. Moreover, we observed the skin quality-of-life scale with skindex-29 and body image disturbance questionnaire (BIDQ) as secondary outcome. Adverse events were recorded as well at every visit. Results : After 4 treatment sessions, there were significant reductions in the number of papules and nodules of the patients. We found that subjective satisfactions of patients were enhanced as well as the objective inflammatory symptoms. We also found significant improvements in the quality of life and BIDQ. No serious treatment-related adverse events were reported. Conclusions : This study demonstrated that standardized facial acupuncture were effective and safe in the treatment of facial inflammatory acnes.

This paper presents the inter-rater reliability of finger spasticity assessment tested realized by using finger simulator that mimics finger spasticity of patients after a stroke. For controlling the simulator torque, finger spasticity was modeled, and the model parameters were obtained by measuring quantitative data while grading based on Modified Ashworth Scale (MAS). A robotic finger simulator was designed for mimicking finger spasticity. Evaluation of this simulator with the help of seven rehabilitation doctors showed that the simulator had a Cohen's kappa value of 0.619 for Metacarpophalangeal Joint and 0.514 for Proximal Interphalangeal Joint. Fleiss' kappa between raters is 0.513 for Metacarpophalangeal Joint and 0.486 for Proximal Interphalangeal Joint. Therefore, the spasticity assessment made by MAS grade system is not reliable owing to the subjectivity of the assessment. The proposed robotic simulator can be used as a training tool for improving the reliability of the spasticity assessment.

Objective : Balloon kyphoplasty is a minimally invasive procedure that is mainly performed for refractory pain due to osteoporotic compression fractures. The purpose of this study was to evaluate the results of balloon kyphoplasty performed at different times after an injury. Methods : In this retrospective study, the records of 99 patients who underwent one level of balloon kyphoplasty between January 2005 and December 2007 were reviewed. The patients were divided into three groups : 21 patients treated within 3 weeks of an injury (the acute group), 49 treated within 3 weeks to 2 months of an injury (the subacute group), and 29 patients treated at more than 2 months after an injury (the chronic group). Clinical outcomes were assessed using a visual analogue scale (VAS). In addition, modified MacNab's grading criteria was used to assess the subjective patient outcome. The radiology findings, including vertebral height restoration and procedure related complications, were analyzed based on the different time intervals after the injury. Results : Patients in all three groups achieved marked pain relief in terms of the VAS within 7 days of the procedure. Good or excellent results were achieved by most patients in all three groups. However, the height restoration, the main advantage to performing a balloon kyphoplasty, was not achieved in the chronic group. Moreover, evidence of complications including cement leakage was observed significantly less frequently in the subacute group compared to the other two groups. Conclusion : Although balloon kyphoplasty is an effective treatment for osteoporotic compression fractures, with regard to pain relief, the subacute stage appears to be optimal for treating patients with a balloon kyphoplasty in terms of achieving the best outcomes with minimal complications.

Objective : Several scales are currently used to assess occlusion rates of coiled cerebral aneurysms. This study compared these scales as predictors of recanalization. Methods : Clinical data of 827 patients harboring 901 aneurysms treated by coiling were retrospectively reviewed. Occlusion rates were assessed using angiographic grading scale (AGS), two-dimensional percent occlusion (2DPO), and volumetric packing density (vPD). Every scale had 3 categories. Followed patients were dichotomized into either presence or absence of recanalization. Kaplan-Meier analysis was conducted, and Cox proportional hazards analysis was performed to identify surviving probabilities of recanalization. Lastly, the predictive accuracies of three different scales were measured via Harrell's C index. Results : The cumulative risk of recanalization was 7% at 12-month, 10% at 24-month, and 13% at 36-month of postembolization, and significantly higher for the second and third categories of every scale (p<0.001). Multivariate-adjusted hazard ratios (HRs) of the second and third categories as compared with the first category of AGS (HR : 3.95 and 4.15, p=0.004 and 0.001) and 2DPO (HR : 4.87 and 3.12, p<0.001 and 0.01) were similar. For vPD, there was no association between occlusion rates and recanalization. The validated and optimism-adjusted C-indices were 0.50 [confidence (CI) : -1.09-2.09], 0.47 (CI : -1.10-2.09) and 0.44 (CI : -1.10-2.08) for AGS, 2DPO, and vPD, respectively. Conclusion : Total occlusion should be reasonably tried in coiling to maximize the benefit of the treatment. AGS may be the best to predict recanalization, whereas vPD should not be used alone.

Objective : The purpose of this study was to investigate the prevalence of and the relevant risk factors for lumbar spondylosis (LS) among middle-aged and elderly rural Korean residents and to explore the association between radiographic LS and lower back pain (LBP) in relation to age and gender. Methods : This community-based, cross-sectional study evaluated 1512 subjects with available radiograph. The prevalence of LBP was obtained using a questionnaire and disability resulting from LBP was measured using a validated Korean version of the Oswestry disability index (ODI). In lumbar spine radiographs, vertebral levels from L1/2 to L4/5 were evaluated for the presence of osteophytes and joint-space narrowing (JSN), and Kellgren-Lawrence (KL) grading was applied. Results : Of 4261 subjects aged 40-79 years, data from 1512 subjects were included. The prevalence of radiographic LS indicated by grade ${\geq}2$ osteophytes and JSN were 53.9 and 15.8%, respectively. Seventy-three percent of subjects had KL grade ${\geq}2$ spondylosis and LBP was present in 36.5% of subjects. Although LS was more common among males, the prevalence of LBP was higher among females. Age, male gender and history of hand or knee arthritis were risk factors for LS. LS was significantly associated with LBP mostly among females over 60 years old and correlated with the ODI after adjusting for age and gender. Conclusion : Our study among rural Korean residents revealed a high prevalence of LS and LBP. The association between LS and LBP was observed mostly among females and LS was significantly correlated with the severity of back pain.

Purpose: The purpose of this study was to update the previously developed nursing practice guideline for enteral nutrition (EN). Methods: The guideline update was done in 22 steps using standardized methodology for nursing practice guidelines. Results: The updated EN guideline consisted of 16 domains and 228 recommendations. The domains and number of recommendations in each domain were for IDSA (Infectious Diseases Society of America): 8 on general instruction, 9 on general instruction for special nutrition, 9 on general instruction for EN, 3 on assessment of EN, 10 on access to EN, 18 on EN device insertion, 16 on selection and preparation of nutritional supplements, 46 on administration and stopping EN, 22 on maintenance and management of EN, 9 on monitoring EN, 16 on prevention and management of complications of EN, 18 on medication administration, 20 on EN in various situations, 20 on prevention of errors, 1 on nursing education, and 3 on nursing documentation. For the levels of evidence, there were 9.7% for level I, 13.1% for level II, 62.5% for level III and 1.1% for GRADE (Grading of Recommendations Assessment, Development and Evaluation): 3.3% for low, 0.8% for moderate, 9.3% for very low. A total of 133 recommendations were newly developed and 10 previous recommendations were modified. Conclusion: This updated EN nursing practice guideline can be used to enhance evidence-based practice in fundamentals of nursing practice and it should be disseminated to nurses nationwide in order to improve the efficiency of EN practice.

Recently web is used for more things than ever before in education. Previous web-based programming education systems help students to check compile errors and runtime errors after submitting programming assignments anytime and anywhere. However, these previous systems cannot quickly provide the detailed assessment results on the generated answer, the coding style, and the plagiarism detection. In this paper, we propose a web-based programming education system to provide the quick results of the detailed assessment as soon as to submit programming assignments. In this system, the plagiarism detection method compares a current file with only the already uploaded files so it can provide quick feedback. The proposed web-based programming education system is applied to a real C programming language class with approximately 40 students. The proposed system tends to improve the students' participation by quick feedback.

Based on basic studies on the current status index of BF certification application for school facilities according to the BF certification implementation, this study sought to improve the direction of the different BF certification evaluation indexes for school facilities by investigating and analyzing the status of BF Reservation Certification for elementary schools. A comparative analysis of the status and evaluation indexes of 30 elementary schools in the Gyeongsang region that included indicators of external and internal facilities, sanitary facilities, guidance facilities, and other facilities indicated that school facilities are insufficient to discriminate based on criteria and thus need to be updated for accurate grading. For school facilities that are open for anyone to use, quality improvement should be induced by improving standards and adjusting points for items that earn middle and lower grades.

Purpose: We investigated the relationship between sonographic measurements of fatty liver and body mass index standard deviation score (BMI-Z score), abdominal wall fat thickness (AWFT), and serum biochemical parameters in childhood obesity. Methods: Anthropometric, laboratory, and ultrasonography data were obtained from 174 children with BMI-Z score >1. After the qualitative grading of hepatosteatosis (grades 0-3), the quantitative liver-kidney echogenicity ratio (LKER) was calculated using a software tool. Groups according to sex, age (AG-I to AG-III), BMI-Z score (BMG-I to BMG-III), and hepatosteatosis degree (HS-I and HS-II) were formed. The differences and distributions of the variables were statistically analyzed and compared among the groups. Results: Serum transaminase and glucose levels showed a positive correlation with LKER, whereas the HDL level showed a negative correlation. BMI-Z score and AWFT showed a positive correlation with fasting insulin level and HOMA-IR value. LKER was significantly higher in girls than in boys (p=0.008). In the AG-I group (age 3-8.9 years), the BMI-Z score was significantly higher, whereas AWFT was significantly lower than in the other age groups (p<0.001). The cutoff point of LKER for predicting grade 2 or higher steatosis (HS-II group) was determined to be 1.83. Cardiovascular disease risk was significantly higher in the HS-II group (p=0.035). Conclusion: As a valuable quantitative measurement tool, LKER can be used for the sonographic screening of fatty liver. AWFT, on the basis of its correlation with fasting insulin level and HOMA-IR value, may be a useful sonographic parameter in the management of childhood obesity.
