The aim of this research is suggesting the method of obtaining well-graded aggregates for concrete replacing the recycled aggregate which size range is from 5 to 13 mm to currently used gap-graded natural aggregates which size range is only 13 to 25 mm. according to the tests results, the workability of concrete was improved with replacing the aggregates of 5 to 13 mm of size range because of compensating gap-grading. Furthermore, there was an improvement in compressive strength when the aggregates of 5 to 13 mm of size range was replaced because obtained well-graded aggregates contributed on increasing adhesiveness and filling internal pore system. Comparing replacing recycled aggregate to natural aggregate, there was no significant difference on the performances.

Objectives : The aim of this study is comparing the improvement of Bell's palsy and Ramsay hunt syndrome according to treatment duration. Methods : The 11cases diagnosed as Ramsay hunt syndrome and 30cases of Bell's palsy who visited Cheong-ju Oriental Medical hospital from February 2006 to June 2008 were evaluated. We used Yanagihara's unweighted Grading System to confirm the improvement. Results : In the analysis of cause, except the "none", the most common cause was "Overwork" in both two group. After 5-day treatment the score was getting worse but after 10-day treatment score was improved in both group. The improvement of Bell's palsy group was better than that of Ramsay hunt syndrome group after 5-day and 10-day treatment, but there was no significance. Conclusions : In comparison of Yanagihara's unweighted grading score checked before treatment, after 5-day, 10-day and 15-day treatment between Bell's palsy and Ramsay hunt sundrome, there was no statistical significant difference.

Beef consumption trends are changing according to consumer needs and preferences. This study was conducted to collect the fundamental information by investigating the consumer's preference and purchase propensity of beef(Hanwoo beef) for improvement of Korean beef grading system. Consumers were recruited from Seoul, Gyeonggi-do, and 5 metropolitan cities, and surveyed from July 24 ~ August 14, 2017. The data obtained from 362 consumers were finally selected for the verification process. Results from the Hierarchical Regression Analysis reveal that the increased purchasing frequency is positively correlated with the following factors, in the consumer group showing preference in the Quality Grade (QG) of beef: marbling type 1QG, fat color 1⁺QG, and income, grade opinion, marbling contents and type 1⁺⁺QG. Conversely, no factor affected the increased purchasing frequency in the consumer group having no preferred QG for beef (p>0.05). Our study determined significant differences in the factors affecting increased purchase frequency of beef among the different groups, classified depending on their preferred QG. The grading system is important since it directly correlates with profit for livestock farmers and the industry. We therefore propose that the grading criteria need to be revised reasonably but scientifically, considering various opinions of the producers and consumers.

Thirty ewes received typical trauma to their oviducts and uterine horns from surgical embryo collection procedures. Ten percent Dexamethasone was used as an irrigant on the exposed abdominal tissue prior to closing the incision. The treatment group received 17mg colchicine Om! lewe) and the control group was administered a 1.0ml placebo(PSS). Fifteen ewes that were initially treated with 17mg /im colchicine showed acute colchicine toxicity within 2-5 days after initial treatment and were removed from the study. Due to acute colchicine toxicity at 17mg, the colchicine level was lowered to 8, 4 and 2mg(4 ewes/group). Treatments consisted of daily injections of colchicine. One ewe in the 8mg group developed toxicity on day 5. Therefore, ewes were then administered colchicine every other day from day 6 to day 14 postsurgeryat 4 and 2 mg. the second laparotomy was performed 9 weeks after first treatment. Following second laparotomy, the treatment group(n=5) received 4 mg colchicine every day for 14 days and there was no clinical symptoms of colchicine toxicity. The third laparotomy was performed by the same operators 5 weeks after final treatment and the adhesions scored. Adhesion grading was based on a scale of 0-4, with 4 being the most severe. The results of adhesion grading(> 3) at second laparotomy were not significantly different(P>0.05)between the two groups. Adhesion formation observed at third laparotomy showed a reduced, but not significant reduction (P>0.05) in the colchicine-treated ewes when compared with the controls. Ten ewes(5 control and 5 treatment)were examined cytogenetically by bone marrow analysis five days post-treatment. There was no difference(P>0.05)in the incidence of numerical or structural aberrations between the two groups.

Purpose: The purpose of this study was to compare the validity of Onen's alternative grading system (AGS) with that of the APDRP and SFU grading systems in patients with isolated and complicated congenital hydronephrosis. Methods: We retrospectively reviewed the medical records of 153 patients (204 renal units) diagnosed with congenital hydronephrosis between January 2002 and December 2011. We classified patients into 2 groups; isolated or complicated hydronephrosis. All renal units were graded according to anterior-posterior diameter of renal pelvis (APDRP), Society for Fetus Urology (SFU) and Onen's grading systems. We analyzed the prognosis of hydronephrosis, according to each grading system, at 2 years of age. Results: There were 152 renal units with isolated hydronephrosis and 52 renal units with complicated hydronephrosis. The isolated hydronephrosis group had a lower grade according to Onen's AGS, and showed more frequent spontaneous remission by 2 years of age. There was more frequent obstruction (P =0.000) and surgical treatment (P =0.000) of units with high-grade hydronephrosis according to Onen's AGS. In the complicated hydronephrosis group the frequencies of spontaneous remission (P =0.015) and renal dysfunction (P =0.013) were significantly higher than those in high-grade hydronephrosis, as indicated by Onen's AGS. There were no significant differences in clinical outcomes among the highest grade groups, according to the 3 systems, in either isolated or complicated hydronephrosis. Conclusion: Onen's AGS reflects the prognosis of hydronephrosis as well as other grading systems in those with isolated hydronephrosis. It was better predictor of renal dysfunction in those with complicated hydronephrosis. However, Onen's AGS was not superior to the other grading systems in terms of predicting prognosis, especially in high-grade hydronephrosis.

Objectives : This study was to compare the incipient grade and improvement rate between each opposite gender and part on peripheral facial nerve paralysis. Methods : We investigated 64 cases of patient with peripheral facial nerve paralysis and divided into four groups with each gender and affected part and compared their incipient grade and rate of improvement. All groups were evaluated by Yanagihara's unweighted grading system before treatment and in everyday and after treatment. Results & Conclusion : 1. There's a difference of incipient grade between each opposite affected lesion in male. But there was not significant statistics. 2. There's no difference of incipient grade between each opposite affected lesion in female. 3. There's a difference of incipient grade between each opposite gender, affected their right side. But there was not significant statistics. Left side affecting palsy is more severe than right in male, and reversed results in female. But there were not significant statistics. There's no differences between each affected lesion in female. 4. There's no differences of improvement rate between each affected lesion in female. 5. The group, affected right side had better rate of improvement than another in male. But it's not significant statistics. 6. Male group had better rate of improvement than female in both gender, affected its left lesion. But it's not significant statistics.

Objectives : This study was to compare effects of scalp acupuncture with usual acupuncture on peripheral facial palsy in comparison with usual acupuncture only. Methods : We investigated 40 cases of patients with peripheral facial palsy, and devided patients into two groups: We treated one group by scalp acupuncture with usual acupuncture and did the other group by usual acupuncture only. To evaluate the effectiveness of treatment applied for two groups, we used Gross Grading System of House-Brackmann(H-B grade), Yanagihara's Unweighed Grading System(Y system). Results : 1. In H-B grade group B(common acupuncture therapy and scalp acupuncture)'s score was reduced than group A(common acupuncture therapy), but there was no statistical significance. 2. In Y-system group B was higher than group A, but there was no statistical significance. Conclusions : There was no stastical significance between two groups : treated by scalp acupuncture with usual acupuncture and usual acupuncture therapy only, on peripheral facial palsy.

Objectives : This study was designed to compare the effects of Jungsongouhyul pharmacopuncture treatment with bee venom pharmacopuncture treatment in hospitalized patients with peripheral facial paralysis. Methods : This study was done on a total of 41 patients with peripheral facial paralysis who were admitted into the Korean Medicine Hospital from February 1st, 2013 to April 30th, 2014. Wedivided patients into two groups. The Jungsongouhyul group was treated by Jungsongouhyul pharmacopuncture once a day and the bee venom group was treated by bee venom pharmacopuncture once a day. To compare the therapeutical effects of the two treatments, we used Yanagihara's unweighted grading system, House-Brachmann grading system, lip-length & snout indices and facial disablity index twice - before initial treatment and after final treatment. Results : Both Yanagihara's score and House-Brachmann grading system score improved in each group. However, there were no significant differences in improvement between the bee venom group and the Jungsongouhyul group. Conclusions : Jungsongouhyul pharmacopuncture treatment appears to be as effective as bee venom pharmacopuncture treatment to improve symptoms of peripheral facial paralysis.

Purpose: Patients with diffuse axonal injury experience various disabilities and have a high cost of treatment. Recent researches have revealed the underlying mechanism and pathogenesis of diffuse axonal injury. This study aimed to investigate the correlation between the radiological grading of diffuse axonal injury and the clinical outcomes of patients. Methods: From January 2011 to December 2016, among 294 patients with traumatic brain injury, 44 patients underwent magnetic resonance imaging (MRI). A total of 18 patients were enrolled in this study except for other cerebral injuries, such as cerebral hemorrhage or hypoxic brain damage. Demographic data, clinical data, and radiological findings were retrospectively reviewed. The grading of diffuse axonal injury was analyzed based on patient's MRI findings. Results: For the most severe diffuse axonal injury patients, prolonged intensive care unit (ICU) stay (p=0.035), hospital stay (p=0.012), and prolonged mechanical ventilation (p=0.030) were observed. However, there was no significant difference in healthcare-associated infection rates between MRI grading (p=0.123). Massive transfusion, initial hemoglobin and lactate levels, and MRI gradings were found to be highly significant in predicting the duration of unconsciousness. Conclusions: This study showed that patients with high grade diffuse axonal injury have prolonged ICU stays and significantly longer hospital stays. Deteriorated mental patients with high energy injuries should be evaluated to identify diffuse axonal injuries by using an appropriate imaging tool, such as MRI. It will be important to predict the duration of consciousness recovery using MRI scans.

Purpose. This study pursued the way for the effective application of the differentiated charge (Nursing grading system) by the nursing manpower which is performed for the nursing service quality improvement to the in-patients in Korea and the minimum employment problem solution of nurses. Methods. For this matter, the status of the nursing grade for 1,452 hospitals (44 high class general hospitals, 259 general hospitals, 265 hospitals, 59 oriental medicine hospitals and 825 recuperation hospitals) was identified which were registered in the Health Insurance Review and Assessment Service in March 2011 status quo. Results. In the most nursing grade by the kind of medical institutions, 70.5% of the nurses were third-graded in upper general hospitals, 38.1% were sixth graded in general hospitals, 62.7% were seventh-graded in oriental medicine hospitals and 40.4% were first-graded in recuperation hospitals. In the nursing grade by the scale of hospitals (in terms of the number of beds), there was a significant difference in general hospitals, but there was no significant difference between oriental medicine hospitals and recuperation hospitals. In the nursing grade by the location of hospitals and the foundation type of hospitals, there was a significant difference between general hospitals and recuperation hospitals. Conclusion. For the effectiveness of applying differentiated nursing fees by the number of nurses, it seems necessary to consider adjusting the present differentiated inpatient-charge system for the better so that small and medium-sized hospitals may induce more nurses.
