The purpose of this case report is to investigate whether an attempt to hold the repeated upright posture under blocking the patient's vision affects the deficits to push away from the paralytic side and the relapse time from down to stand up position without push away in patients with hemiplegia with pusher syndrome. Two hemiplegic patients with pusher syndrome were assessed. The task was performed 4 times per day for 6 weeks. The modified barthel index (MBI) was performed to assess activities of daily living (ADL). For assessing balance, the "balanced sitting" and "sit to stand" are analyzed using by modified motor assessment scale (MMAS). The scale for contraversive pushing (SCP) was used for determination of push away from paralyzed side. MBI, MMAS and SCP were assessed before and after trial of the task. In patient 1, total score of the scale is 0 in sitting posture and standing posture within 3 weeks and 4 weeks, respectively, In patient 2, total score of the scale is 0 in sitting posture and standing posture within 4 weeks and 6 weeks, respectively. These results demonstrated that pusher syndrome was completely resolved in at least 6 weeks. Our findings indicate that this physical therapy seems to be relevant for the hemiplegic patients with pusher syndrome.

The structural characteristics of small scale rice polisher was analyzed to improve its performance. Spraying characteristic of nozzles used for rice polishing was also analyzed by a machine vision system. The internal pressure of the polishing chamber was measured according to outlet resistance, water spraying , and roller shaft speed. In addition , the performance of the rice polisher was evaluated to improve it in the basis of internal pressure in polishing chamber, whiteness , and broken rice ratio of clean rice according to the operating conditions. Actual nozzle discharge rate and drop size were 125cc/min and 86.97㎛, respectively. In the case of water spraying on rices, the internal pressure showed 4.9-9.8N/㎠ increase, broken rice ration decreased , and there was no difference in whiteness . The internal pressure increased up to two time with the increase of the outlet resistance. Also, the pressure at the upper part of screen was one and half times as high as the pressure at the lower part. In the case of water spraying rate of 150 cc/min, the roller shaft speed of 850 rpm resulted in no difference in whiteness and decrease of 0.3%in broken rice ratio, comparing to the roller shaft speed of 950 rpm.
Today, rolling stock has become a fast and convenient mode of transportation and has witnessed increased demand. But the speed improvement has resulted in increased aerodynamic noise and therefore residential districts near the railroad tracks are exposed to ever increasing noise level. A study on methodologies for measuring and appraising rolling stock's environmental noise has therefore become an important area of endeavor. In the case of the environmental noise, there are no changes in tone so prediction can be made by reducing areas around the railway. The present study explores estimation of the noise around the railway using scale model, and the source of the noise has been investigated as well. The scale model of rolling stock will have to be able to measure high frequency noise and it is required to be generated in a short amount of time. Since popping a balloon or firing a gun fits this requirement the present study analyzed the characteristics of these two different noise sources. Measurement was made in a large vacant lot and the reflection due to the ground was also examined. The method proposed here can be used in the future for predicting the environmental noise of railway vehicles.

This research presents dynamical reaction investigation of pore-dependent and nano-thickness beams having functional gradation (FG) constituents exposed to a movable particle. The nano-thickness beam formulation has been appointed with the benefits of refined high orders beam paradigm and nonlocal strain gradient theory (NSGT) comprising two scale moduli entitled nonlocality and strains gradient modulus. The graded pore-dependent constituents have been designed through pore factor based power-law relations comprising pore volumes pursuant to even or uneven pore scattering. Therewith, variable scale modulus has been thought-out until process a more accurate designing of scale effects on graded nano-thickness beams. The motion equations have been appointed to be solved via Ritz method with the benefits of Chebyshev polynomials in cosine form. Also, Laplace transform techniques help Ritz-Chebyshev method to obtain the dynamical response in time domain. All factors such as particle speed, pores and variable scale modulus affect the dynamical response.

Purpose: The efficacy of periarticular multimodal drug injection and adductor canal block after a medial opening-wedge high tibial osteotomy was compared in terms of the postoperative pain level. Materials and Methods: From November 2016 to March 2017, 60 patients underwent a medial opening-wedge high tibial osteotomy under spinal anesthesia. Preemptive analgesic medication, intravenous patient controlled anesthesia were used for pain control in all patients. Thirty patients received a periarticular multimodal drug injection (group I), and 30 patients received an adductor canal block (group II). These two groups were compared regarding the postoperative pain level, frequency of additional tramadol injections, total amount of patient-controlled analgesia, and number of times that the patients pushed the patient-controlled analgesia button at each time interval. Results: The visual analogue scale scores over the two-week postoperative period showed no statistical significance. The frequency of additional tramadol hydrochloride injections was similar in the two groups over time. The mean number of times that patients pushed the patient-controlled analgesia button was similar in two groups over time. The total amount of patient-controlled analgesia was similar in the two groups over time. Conclusion: This study shows that intraoperative periarticular multimodal drug injections and adductor canal block may have a similar effect on postoperative pain control in patients who have undergone a medial opening-wedge high tibial osteotomy for unicompartmental osteoarthritis of the knee.
The study examined the effects of San-Yin-Jiao(SP-6) acupressure treatment on labor pain, length of delivery and anxiety for women in the labor. The effects of using SP-6 acupressure were evaluated by comparing two groups, a SP-6 acupressure group (22) and a control group (17), for a total of 39 women in labor who had a normal vaginal delivery. Data were collected using a structured questionnaire which included general characteristics, a subjective labor pain scale, measurement of duration of delivery time and a subjective anxiety scale. Data were collected before treatment (pre) and after treatment (post). The results of this study are summarized as follows : 1. The post-scores for total labor pain increased over the pre-scores but the difference between the two groups was not statistically significant(p=0.219). Wilcoxon signed rank test of the difference in pre-post labor pain scores for the SP-6 acupressure group was not statistically significant (p=0.081) but the increase for the control group was statistically significant (p=0.001). 2. The length of time for the delivery in the group which had the SP-6 acupressure was shorter (143.91${\pm}$67.77) than the control group (197.94${\pm}$89.64). The difference between the two groups was statistically significant (p=0.028). 3. The post-scores for anxiety increased over the pre-scores but the difference between the two groups was not statistically significant (p=0.426). The scores of SP-6 acupressure group did not show a significant increase by the Wilcoxon signed rank test (p=0.194) but in the control group showed a significant increase (p=0.008).This study showed that SP-6 acupressure was effective in relation to labor pain, length of time for delivery and anxiety for labor women. But it is necessary to replicate the study with a larger number of participants to generalize the results.
The concentration of gaseous mercury (Hg) was measured at hourly intervals along with relevant environmental parameters from two monitoring stations (Hannam and Kwachun) in Seoul metropolitan city during September 1999 to July 2000. Irrespective of the environmental and areal differences in the two locations, the concentrations of observed Hg levels were remarkably compatible each other. The results showed that the mean Hg level in Hannam was measured to be 5.34${\pm}$3.92 ngm$^{-3}$ (N = 2576), while that of Kwachun was 5.25${\pm}$2.53 ngm$^{-3}$ (N = 1992). Using these measurement data, we inspected Hg distribution and behavior at various time scale. When the data were analyzed at 24 hr scale, the distribution patterns for the two areas were distinguished by enrichment in either night(Hannam) or day (Kwachun). The patterns for seasonal distributions were also opposing each other such as the occurrences of peak during winter (Hannam) or summer (Kwachun). In order to analyze the factors affecting Hg distributions between two sites over different time scale, we conducted both correlation and factor analysis on both all data sets and on seasonally divided data groups. Whereas Hg exhibits strong correlations with such parameters as PM (particulate matter), SO$_2$, and NO$_2$, its relationship with meteorological parameters was not significant enough in many cases. The results of factor analysis also indicated that the Hg levels are tightly associated with most pollutants, explaining the largest portions of statistical variance. According to our study, we conclude that patterns of Hg distributions can exhibit variable patterns depending on local source processes which we expect to be diverse among different areas.
It is known that aggressive treatment of chemotherapy, radiation and autogenous stem cell transplantation is effective for prevention of recurrence in the high-risk breast cancer patients. It was assumed that this procedure takes a longer time and decreases the quality of life more than the standard adjuvant chemotherapy. However, there are few studies comparing the quality of life of patients having bone marrow transplantation and adjuvant chemotherapy. Most of the studies were focused on the quality of life in one point of time, such as only during the early treatment stage, only overall quality of life rather than specific dimensions of the quality of life. The purposes of this study are 1) to identify the difference of the quality of life between two different treatment patterns, adjuvant chemotherapy and autogenous stem cell transplantation: 2) to identify the mostly affected dimension and the periods of time affected by the treatment patterns; and 3) to identify the trajectories of quality of life in each treatment pattern. This is a time series design that measures 4 different points of times. At the beginning of the study, 19 patients were placed in the chemotherapy group and 12 in the group of auto-peripheral blood stem cell transplantation. The inclusion criterion was the advanced disease stage of 3 or over with metastasis of more than 5 lymph nodes. The exclusion criteria were 1) anyone who has metastasis to other organ; 2) anyone who had psychological problems. Ferrell's Quality of Life Scale for Cancer Survivors 41 items on a 10 point scale was used. The QOL-CS includes 4 dimensions, which were labeled physical, psychological, social, and spiritual. The Cronbach‘s alpha of this scale was 0.89. Mann-Whitney U test and Friedman test were used to test each hypothesis. In comparison of the two groups, the quality of life of the bone marrow transplantation group dramatically increased at the 3rd and 6th month after transplantation, while the chemotherapy groups results stayed lower. The most affected dimension of the quality of life at the end of the treatment was the physical dimension. However, it and increased along with time, while the psychological dimension values remained low over the long-term period. Intensive nursing care is needed during the entire period of chemotherapy in all patients having chemotherapy, and is also required for right after cases of bone marrow transplantation.
We analyzed two radiocarbon-dated lagoonal sediment cores from Cheonjinho and Ssangho using various biogeochemical methods. As a result, the start times of rice agriculture are estimated to be AD 780 for Cheonjinho and 100 BC for Ssangho. There is a large temporal difference in the beginning of rice agriculture between two study sites even though they are closely located on the coast. This result indicates that pollen records are not sufficient to approximate the start time of rice agriculture accurately. A temporal lag seems to exist between the time when rice agriculture was first introduced and the time when full-scale rice agriculture began in the Yeongdong region, probably because of low agricultural productivity. In both study sites, rice agriculture intensified and slope erosion increased 250 years after full-scale agriculture began. This suggests that intensified rice agriculture resulted in an increased number of inhabitants, settlement expansion to hilly areas, and the consequent deforestation.
Purpose: Specialized general trauma surgeons play an important role in the care of trauma patients. Hemoperitoneum is a severe, but representative, condition following a life-threatened trauma. The objective of this study was to compare the outcomes for polytrauma patients with hemoperitoneum between the periods during which a trauma surgeon was available and that unavailable. Methods: Thirty-one trauma patients with hemoperitoneum who were treated at Korea University Guro Hospital over a period of 4 years were included in this study, and their case records were analyzed retrospectively. The patients were divided into two groups, the 2011 and 2012 group and the 2013 and 2014 group corresponding, respectively, to the periods that a trauma surgeon was not and was working. Vital signs on admission, scores on the injury severity scale and, Glasgow coma scale, elapsed time to diagnostic, and therapeutic, and/or operative interventions were studied. The effects on intensive care unit and hospital lengths of stay, as well as mortality, were also studied. Results: The study population consisted of 16 and 15 patients in group 1 and 2, respectively. The patients in both groups had six unstable hemodynamic on admission. The time to the main procedure (intervention, operation etc.) was longer during the periods when a trauma surgeon was not working than it was during the period when working. This difference did not reached statistical significance. The mortality rates for the two groups were not statistically different either (18.75% vs 26.67%; p=0.928). Conclusion: Having at least one specialized general trauma surgeon on duty may reduce the time to intervention and surgery for severe trauma patients with hemoperitoneum, but appears to have no effect on the mortality rates. In conclusion, having only one trauma surgeon on duty does not improve the quality of care for trauma patients.
