Purpose: The purpose of this study is to investigate correlations in vital sign changes, the severity of pain, signs of complications, and the duration of sandbag management in order to suggest a standardized practice related to sandbag management in children with Nephrotic Syndrome(NS). Method: From October 2000 to May 2001, seventy children with NS who underwent kidney biopsy were interviewed at one hospital in Seoul Korea, and participated in this study. Result: 1) The average sandbag applying time after kidney biopsy was 18.1 hours. 2) Systolic blood pressure and respiration increased until 15 minutes after kidney biopsy, after then, they decreased signifi- cantly (systolic BP, p= .006; respiration, p= .029). However, no significant changes were noted in diastolic blood pressure and pulse. 3) Pain was reported minimal for 1 hour after kidney biopsy. The severity of pain increased until 12 hours after the procedure, then, decreased significantly(p= .0001). 4) Reported complications were hematuria (74.7％) and abnormal sonogram (32.9％). No apparent bleeding on the biopsy region was reported in any children. Conclusion: From these findings, it is possible to change the protocols of the duration of absolute bed rest time and sandbag application management shortly after kidney biopsy. But it is needed to study the fit protocols for kidney biopsy. Several implications in nursing practice are suggested. 1) Replicated studies for more participants are needed. 2) Further research on the effect of sandbag application after kidney biopsy is required. 3) The best duration of sandbag application management after kidney biopsy need to be investigated.

Purpose: This study aimed to investigate the differences in exudate and bleeding incidence and the changes in back pain and discomfort based on the weight of a sand bag applied to the femoral puncture site after hepatic transcatheter arterial chemoembolization. Methods: This quasi-experimental study comprised 82 patients randomly divided into three different groups. Experimental group 1 patients had a 600g sandbag, experimental group 2 patients an 800g sandbag, and control group patients a 1900g sandbag, on femoral access sites post procedure. The three groups of patients were assessed on level of exudate and bleeding and asked about back pain and discomfort at 30, 60, 120, 180 and 240 minutes after the procedure. Results: There were no significant differences in exudate and bleeding between the three groups before and after application of the sandbag post procedure. Both back pain and discomfort were significantly lower in the experimental groups than in the control group. Conclusion: There was no significant effect on bleeding and exudation due to the weight of the sandbag. The lowest level of back pain and discomfort was found in the group with the lightest weight (600 g). Therefore, the use of lighter-weight sandbags to prevent post procedure vascular complications is proposed.

Objectives The purpose of this study was to compare the effects of MSAT (Motion style acupuncture treatment) using Sandbag regarding low back pain with HIVD of L-SPINE. Methods Forty patients received inpatient treatment from March 16 to May 16, 2015 in the Daejon-Jaseng oriental medicine hospital were divided into 2 groups by blocked randomization: Group A (n=20) is routine treatment on HIVD of L-SPINE with MSAT using Sandbag and Group B (n=20) is routine treatment on HIVD of L-SPINE (acupuncture, Shinbaro pharmacopuncture, herb medication, chuna treatment and physiotherapy). The MSAT (Motion style acupuncture treatment) using Sandbag was administered each day and both groups were received routine treatment each day. Evaluations were made before treatment, after 3 days and 7 days, and before discharge using the NRS (numeric rating scale) and ODI (oswestry disability index). The statistically significance was evaluated by SPSS 22.0 for windows. Results The NRS (numeric rating scale) and ODI (oswestry disability index) of both A and B groups after 3, 7 days and before discharge of treatment significantly decreased (p<0.05). Regarding group comparison, the NRS (numeric rating scale) and ODI (oswestry disability index) of A group was significantly lower than the B group at 3, 7 days, before discharge (p<0.05). Regarding improvement of the NRS (numeric rating scale) and ODI (oswestry disability index), A group was significantly lower than the B group at 3 day (NRS), 7 day (ODI) (p<0.05). There was significant difference between two groups at 7 days (NRS) and before discharge (p<0.05). Conclusions Compared to routine treatment, the MSAT (Mostion style acuputure treatment) using Sandbag significantly improved the NRS (numeric rating scale) and ODI (oswestry disability index) after 3, 7 days, and before discharge. Because early intervention determines the grade of Low back pain with HIVD of L-SPINE, the MSAT (Motion style acupuncture treatment) using Sandbag will be clinically helpful to patients at the early stage.

Objective: This study aimed to determine the effect of wrist and trunk weight loading using sandbags in stroke patients in order to provide the quantitative data for enhancement of gait movement. Method: Twelve stroke patients, who have been diagnosed with hemiplegia over a year ago, were participated in this study. All subjects were asked to perform normal walking [N], wrist sandbag walking [W], wrist & trunk sandbag walking [WT], and both wrist sandbag walking [B] and both wrist & trunk sandbag walking [BT], respectively. Eight infrared cameras were used to collect the raw data. Gait parameters, arm swing, shoulder-pelvic kinematics, and lower extremity joint angle were calculated to examine the differences during walking. Results: As a result, there were no significant differences in the gait parameters, shoulder-pelvis, and lower extremities joint angles, but significant differences were found in the range of motion and the anteversion in arm swing. Conclusion: Wrist and trunk weight loading using sandbags affected the movement of the upper extremities only while it did not affect the movement of the lower extremities. It implies that it can reduce the risk of falling caused by a sudden movement change in lower extremities. In addition, the wrist and trunk weight loading using sandbags can induce changes in movement of the upper extremities independently and contribute to functional rehabilitation through resistance training.

In this study, Generally sandbag was used to reinforce slope or restore levee by using the in-situ material. To increase shear strength of sandbag, the Velcro system was effective for geosynthetic interface and make up for the weakness of shear strength between sandbag to sandbag. In this study, shear properties of geosynthetic-geosynthetic and geosynthetic-soil were evaluated from large scale direct shear tests. The cohesion and the angle of internal friction of each interface was evaluated. And laboratory model tests were performed to compare strength of reinforcement with strength of none reinforcement. As a result of this study, the cohesion and the angle of internal friction of each interface was increased, especially the cohesion was increased more than the angle of internal friction. Also according to the result of model test, the bearing capacity was increased by 20%.

Most of the vascular procedures performed for various diagnoses and treatments of various abdominal intervention procedures performed by the Department of Radiology and Angiography are performed by puncture of the femoral artery. For this reason, patients should undergo blood-related tests such as prothrombin time (PT) and partial thromboplatin time (PTT). Therefore, many patients are instructed to take precautions such as putting a sandbag on the puncture site to prevent delayed hemorrhage after hemostasis of the femoral artery puncture site, and not to bend the leg of the treated area for about 3 hours. Because of this, many patients have complained of pain during the procedure and inconvenience during the absolute bed rest time in the ward. The purpose of this study was to compare the safety of balloon ancillary devices with sandbags placed on the hemostasis site to prevent delayed hemorrhage after arterial puncture. We compared the safety of each patient with the results of medical records in consideration of the problem that the patient could not press with the focus, the position of the patient was changed depending on the patient's body shape, and the problem of falling down according to the location of the puncture site. As a result, the use of a balloon type ancillary device improves the effect of continuous hemostasis, reduces discomfort during the patient's absolute stabilization time, increases the patient's satisfaction, and is a good alternative to the existing sandbag.

Shear properties of geosynthetic/geosynthetic and geosynthetic/soil were evaluated from direct shear tests. The type of geosynthetic is Velcro which is effective for geosynthetic interface and make up for the weakness of sandbag. In this study, the cohesion and the angle of internal friction of each interface was estimated. The test results showed that the cohesion and the angle of internal friction of the geosynthetics depended on the amount of normal stress, the type of the geosynthetics used, and combinations of the geosynthetics and soils. Finally, by comparing the apparent cohesion and the friction angle of the geosynthetics, the applicability to design was identified.

Purpose: This study examined the effects of e position change upon reported discomfort and bleeding complications during bed rest following a liver biopsy. Methods: The research design for this study was a non-equivalent control group quasi-experimental design. Twenty-nine participants were assigned to the treatment group and twenty seven participants were in the comparison group. Following the biopsy, the treatment group participants had a position change from the supine without compression for two hours followed by compressive right lateral position for two hours. The comparison group maintained continuously the compressive right lateral position with sandbag for four hours. Results: There were statistically significant differences in reported discomfort between the treatment and comparison groups following the intervention. No significant differences were found in bleeding complications between the two groups. Conclusion: The results of the study suggest that the positional change is an effective nursing intervention in reducing discomfort without risk of bleeding following a liver biopsy.

Forest roads failure is one of the most common problems caused by heavy rainfalls. This study investigated the characteristics on stabilization measures installed for cutting slopes failure of forest road resulted from heavy rainfalls. Three primary factors (slope length, slope gradient, soil type) affecting cutting slope failure were considered and stabilization measures were classified into two types (A type: wooden fence, vegetation sandbag, stone masonry; B type: wire cylinder, gabion, concrete retaining wall) through discriminant analysis based on their capacity of resistance to slope failure. Results showed that A type was mainly installed in such conditions as cut slope <8 m, cut slope gradient $30-40^{\circ}$ and soil type with soil while B type occurred in locational conditions as cut slope length >8 m, cut slope gradient < $30^{\circ}$ and > $30^{\circ}$, and soil type of gravelly soil and rock.

Transarterial chemoembolization is one of the most representative procedures for puncture of the femoral artery. In addition, the same procedure is often repeatedly performed many times, and Hepatocellular carcinoma patients due to cancer is significantly lowered blood tests, regardless of platelet counts are not good enough to stop bleeding. More importantly, hepatocellular carcinoma has a high degree of complication and disease severity, which makes it less likely that the condition of the body will be relatively inferior to other patients. In order to prevent delayed hemorrhage of the femoral artery puncture site after the procedure, it is advised to absolutely stabilize the limb so that it does not bend the limb for 3 hours after climbing in the ward. Therefore, I have been complaining about inconvenience. In addition, in order to prevent delayed hemorrhage after hemostasis, balloon type hemostatic device was used instead of sand bag which was placed on hemostatic site. The results of this study were compared with the results of actual application. The use of a balloon-type hemostatic device to increase the effectiveness of continuous hemostasis and to minimize the inconvenience during the time of patient's absolute bed rest, rather than raising the sandbag to prevent primary delayed hemorrhage by various methods in transarterial chemoembolization. It can be used as a substitute for existing sand bags because it can alleviate pain, increase satisfaction, and can be used as a disposable one.
