The purpose of this study was to investigate the effect of Treadmill Training with FES(TTF) on walking velocity, gait endurance, and energy expenditure index(EEI) of hemiplegia patients with foot drop. Two subjects with hemiplegia participated in this study. They took walking excercise 5 times per week for 8 weeks. One time excercise spent 30minutes. The theraputic effect was evaluated by how many seconds they needed to walk 10 meters, how far they could walk for 12 minutes, and how much they spent energy in walking for 12 minutes. Two cases were examined before, after 4 week, and after 8 week, walking training. The results of this study are as follows; 1) Walking velocity : Case 1 increased from 0.52m/sec before walking training to 0.83m/sec after 8 weeks. Case 2 increased from 0.58m/sec to 0.92m/sec. 2) Gait endurance : Case 1 increased from 383.23m to 625.53m. Case 2 increased from 410.19m to 693.47m. 3) EEI : For comfortable walking condition, Case 1 decreased from 0.98beats/min to 0.71beats/min, and Case 2 decreased from 0.93beats/min to 0.68beats/min. For maximum walking condition, Case 1 decreased from 0.93beats/min to 0.67beats/min, and Case 2 decreased from 0.91beats/min to 0.61beats/min. The findings suggest that hemiplegia patients can improve their walking velocity, gait endurance and energy expenditure index through TTF.

The purpose of this paper is to analyze the relationship between meteorological factors and agricultural reservoir storage, and predict the reservoir storage by multiple regression equation selected by high correlated meteorological factors. Two agricultural reservoirs (Geumgwang and Gosam) located in the upsteam of Gongdo water level gauging station of Anseong-cheon watershed were selected. Monthly reservoir storage data and meteorological data in Suwon weather station of 21 years (1985-2005) were collected. Three cases of correlation (case 1: yearly mean, case 2: seasonal mean dividing a year into 3 periods, and case 3: lagging the reservoir storage from 1 month to 3 months under the condition of case 2) were examined using 8 meteorological factors (precipitation, mean/maximum/minimum temperature, relative humidity, sunshine hour, wind velocity and evaporation). From the correlation analysis, 4 high correlated meteorological factors were selected, and multiple regression was executed for each case. The determination coefficient ($R^{2}$) of predicted reservoir storage for case 1 showed 0.45 and 0.49 for Geumgwang and Gosam reservoir respectively. The predicted reservoir storage for case 2 showed the highest $R^{2}$ of 0.46 and 0.56 respectively in the period of April to June. The predicted reservoir storage for 1 month lag of case 3 showed the $R^{2}$ of 0.68 and 0.85 respectively for the period of April to June. The results showed that the status of agricultural reservoir storage could be expressed with couple of meteorological factors. The prediction enhanced when the storage data are divided into periods rather than yearly mean and especially from the beginning time of paddy irrigation (April) to high decrease of reservoir storage (June) before Jangma.

In this study, experiments were carried out to investigate the characteristics of grinding and wear process of diamond wheel grinding ceramic materials. Normal component of grinding resistance of $AI_2O_3$ was less then that of $Si_3N_4$ and $ZrO_2$. It is because the resistance for grain shedding is less then that for layer formation. For the case of $Si_3N_4$ and $ZrO_2$, as the grain mesh number of wheel increases, the surface roughness decreases. For the case of $AI_2O_3$, the surface roughness does not decreases. For the case of $Si_3N_4$ and $ZrO_2$, grinding is carried out by abrasive wear processes. For the case of $AI_2O_3$, grinding is carried out by grain shedding process.

A retrospective double blind study comparing 7 day with 2 day regimen of antibiotic prophylaxis was conducted among 200 patients undergoing open heart surgery. No case of endocarditis and wound infection occurred. Pneumonia developed in 5 cases of the 7 day and 1 case of the 2 day group. Urinary tract infection without clinical significance developed in 1 case of the 7 day and 3 cases of the 2 day group. Bacteremia developed in 2 cases of the 7 day and 1 case of the 2 day group. We concluded as follows: l. Administration of antibiotics for 2 days appears to be without substantial risk of infection comparing long term 7 day regimen. 2. 7 days of antibiotics may actually increase the risk of serious infection such as nosocomial pneumonia, and predispose to the development of infections with fungi or antibiotic resistant bacteria. 3. 2 days of prophylaxis is more beneficial than long term 7 day regimen for example economically.

Impulsive vibration velocity is monitored at the surface and the boundary surface of rocks as various impulsive forces of horizontal and vertical directions were given to rocks which had difference in uniaxial compressive strength for investigate to the vibration velocity of rocks according to the impulsive direction and the monitoring site. The vibration velocity of the boundary surface of rocks was about 2.9 times or much larger than that of the surface at the same scaled distance in the case of horizontal impulsive forces, and was above 4.2 times in the case of vertical impulsive forces. The attenuation exponents of the vibration velocity equations in the surface and the boundary surface of rocks make a vast difference with the impulsive directions, but is makes little difference in the case of the same impulsive direction. The ratio of vibration constants of the surface to the boundary surface of rocks is that square and cube root scaled equation is a range of 2.7∼3.0 and 4.9∼5.0 respectively in the case of horizontal impulsive forces, and is a range of 4.2∼5.7 and 7.7∼11.5 respectively in the case of vertical impulsive forces.

Two bitches were presented to the Teaching Animal Hospital, Chonbuk National University with vagina prolapse along with prolapse of the bladder. Case 1 was a 2 years old, 38.5 kg, female Tosa dog which had slight shock and depression. She had a labor pain vagina prolapse since last 3 days. Case 2 was a 2 years old, 25 kg, female Rottweiler dog which was presented with the similar clinical signs with case 1. In both the dogs we performed plain radiography, CBC, blood chemistry and urine analysis. In case 1, we performed cesarean section along with the repositioning the vagina and the bladder. We found 13 fetuses among which 7 were alive. In case 2, we also performed cesarean section and recovered the fetuses. There were 7 fetuses but only one was alive. Among the 6 dead fetuses 3 were congenitally deformed. Then we reduced prolapsed vagina and bladder, and repositioned them. After that we performed ovariohysterectomy. Both the bitches become recovered from the prolapse of the vagina and bladder and there was no recurrence of the condition.

Objectives: Case report is a description of medical experience that contains a patient's information and treatments. It has been used to determine the effectiveness and side effect of the treatments. Case report can be used for medical, scientific, or educational purposes. The objective of this study was to evaluate the quality of case reports published in Journal of Oriental Neuropsychiatry from 2013 to 2017 using CARE and CARES guideline. Methods: Case reports were selected from Journal of Oriental Neuropsychiatry and their quality assessed using CARE guideline and CARES guideline. The items of CARE and CARES guideline were assessed as 'Sufficient', 'Not sufficient', 'Not reported', 'Not applicable'. The outcome was analyzed using case reports and items. Results: 26 case reports were selected. For CARE guideline, 'Sufficient' percentage was min at 22.2%, max at 46.4% with a median of 39.3%. Sum of 'Sufficient', 'Not sufficient' percentage was min at 59.3%, max at 85.7% with a median of 75.0%. Items 'Timeline', 'Diagnostic assessment', 'Follow up and outcomes', 'Informed consent' were not reported in more than 50% of all case reports. Items 'Keywords', 'Abstract', 'Introduction', 'patient information', 'Diagnostic assessment', 'Therapeutic interventions', 'Follow up and outcomes' were not sufficiently reported in more than 50% of all case reports. For CARES guideline, 'Sufficient' percentage was min at 0%, max at 50% with a median of 0%. Sum of 'Sufficient', 'Not sufficient' percentage was min at 33.3%, max at 100% with a median of 92.9%. Items of herbal prescription 'herb', 'decoction', 'use', items of acupuncture treatment 'materials', 'techniques', items of moxibustion treatment 'materials', 'techniques' were not sufficiently reported in more than 50% of all case reports. Conclusions: The reporting rate of items was good. But the quality of reporting was low. Also, particular items were not reported frequently. Therefore, there is a need to improve the quality of case reports in Journal of Oriental Neuropsychiatry.

Investigating the existence of volume-outcome relationships for specific disease groups relates directly to the policy issue of whether, and how, specific inpatient services should be regionalized. This study examined whether medical costs and lengths of stay as outcomes were affected by changes in volume within hospitals. Based on the claims data obtained from National Federation of Medical Associations, each six disease categories from medical and surgical conditions were selected and 29,720 cases from 1,266 hospitals were analyzed. Main findings of the research can be summarized as follows: 1. Analyzing volume and cost per case relationship, tonsillectomy class 1, hernia procedure class 0, appendectomy and cesarean section class 0,1 in surgical conditions showed negative relationship significantly. In cases of medical conditions, costs per case in respiratory neoplasm class 2, COPD class 1, 2, digestive malignancy were also related to volume negtively. 2. Comparing volume with length of stay per case, lens procedure class 0, hernia procedure class 0, appendectomy class 0,1, cesarean section class 1 in surgical conditions showed negative relationships significantly. In medical conditions, volume of respiratory neoplasm class 2, COPD class 1,2, digestive malignancy class 0 were associated with negatively. 3. Within same disease categories, changes in cost and length of stay per case to volume were more remarkable in severe cases. These results suggested a significant inverse relationship between disease cases and cost, length of stay per case as outcome variables.

Effects of rotor-stator blade count ratio on the unsteady aerodynamic characteristics of a cascade was studied by using a Navier-Stokes code. Present Navier-Stokes code is a parallel code and works on a multi-cpu machine. It is based on the SIMPLE algorithm and uses QUICK scheme for convection terms and second order back difference for all temporal derivatives. Computations were carried out for two cases : case 1 is for 3 stator cascade passages subjected to two upstream wakes while case 2 is for 2 stator cascade passages subjected to three upstream wakes. Numerical solutions show that rotor-stator blade count ratio plays a significant role in the unsteady aerodynamic characteristics of the stator cascade. Case 2 shows smaller unsteady fluctuation than case 1, even if they show the same time averaged value. The smaller fluctuation of case 2 is believed due to strong interaction between unsteady vortices. The unsteady lift variation of case 2 is shown to have many high frequency fluctuations as more unsteady vortices travel around the cascade. The unsteady turbulent kinetic energy due to the upstream wake is also shown to decay faster through the cascade passage than in the free stream.
