  • Background: This study investigated effective posture for gluteus medius rehabilitation training and effects of isometric muscle activity by electrophysiology through EMG while performing dynamic isotonic behavior of weight placed differently on upper limbs. Method: 16 healthy male subjects 20 to 29 years of age volunteered for the study. Lateral stabilizer right gluteus medius activity was assessed using EMG while the right lower extremity maintains single limb support, and the left upper extremity elevation movement maintains 5 seconds without load, 1RM to 1 repetition, 5RM to 5 times, 10RM to 10 times, 5RM and 10RM maintain 5sec. Results: Comparison of the mean value of EMG data showed a statistically more significant difference in upper extremity elevation movement on opposite upper extremity added weight than one that was not added on a single limb weight bearing posture(p>.05). Weight supported side gluteus medius activity for 1RM, 5RM, 10RM weight difference and movement repetition did not differ(p>.05). Comparison in maximum value showed statistically significant differences in not adding weight on upper limb elevation exercise and 1RM, 5RM, 10RM repeated behavior. Elevation behavior and repetition appeared over 70% of MVIC. Conclusion: Unilateral weight bearing stance added weight in the opposite upper limb elevation movement was an indirect exercise to effectively stimulate gluteus medius activity. Applying various added weight will have effective exercise on the early stages of rehabilitation because activity gluteus medius did not differ through added weight.

  • Given the structure of Korean mountains, it is more appropriate to apply the relative elevation method than the absolute elevation method. However, so far there were not suitable quantitative methodologies to analyze relative elevation, these analytical concepts were difficult to be utilized in urban environmental planning. This study suggested three methods for analyzing relative elevation, and one method for setting the analytical scope of relative elevation by calculating terrain relief. The results showed that the procedure considering 500m radius of each point and standardizing to 30% of the 7th height ridge was the most effective method to extract the local topography. This methodology is the quantitative tool to be able to conserve local important hills and ridges, and apply to fields of urban environmental planning and ecological restoration, especially urban ecological network.

  • The research of cold therapy is preceding rarely nowadays. This study was researched to measure the skin temperature of the right foot malleolus when the leg change the situation precisely speaking it was cold, elevation, cold plus elevation. Twenty young healthy volunteers(M:10, F:10)with no history of cardiopulmonary disease, peripheral artery disease were tested. This study were analyzed by one-way-repeated ANOVA. In the first we examined the within changes of the skin temperature between before and after examination for each modality. The skin temperature at all of modalities had fallen. Therefore we could know the fact that elevation plus cold modality had fallen skin temperature significantly more than elevation or cold. And there were no significant difference between male and female. We conclude that elevation and cold therapy could be better effective on edema, contusion and sprain than cold or elevation therapy independently.

  • The average temperatures by the land cover class, by the elevation extent, by the slope and by the aspect have been calculated using multitemporal Landsat TM band 6 and DEM. For this, the TM band 6 data from October 21, 1985, June 2, 1992, September 1, 1996, May 7, 2000 and the 28.5m x 28.5m grid elevation data of Seoul have been used. From the varying curve of the average land surface temperature by the elevation extent, the presence of the atmospheric inversion phenomenon and the scope of the inversion layer can be inferred. Especially, the average land surface temperature by the aspect can be effective for deciding a road line. For these reasons, it is expected that temperature estimation using remote sensing data shall be effective for the survey of heat damage, environmental temperature monitoring, and urban and environmental Planning usage.

  • Purpose: Leg elevation is known as an effective method for reducing leg swelling, and it has been routinely used in medical practice. However, the effect of swelling reduction in relation to the degree of elevation height is not known. This study evaluated the swelling of the leg after acute ankle fracture operations at two different elevation heights and the elevated leg heights were compared. Materials and Methods: A total of 66 patients with postoperative acute ankle fractures were classified into two groups depending on the presence of different leg elevation heights: high-elevated (HE, case) and low-elevated groups (LE, control). We checked leg swelling, pain, subjective satisfaction for the elevation device, and the American Orthopedic Foot and Ankle Society (AOFAS) score, and we retrospectively compared them between both the groups. Results: Leg swelling and pain were reduced in both groups. However, they did not show any significant differences between both the groups (p>0.05). Nineteen patients in the HE group replied with uncomfortable, while no patients in LE group did so. The AOFAS score at 1 year postoperatively did not show any significant differences between both the groups (p=0.46). Conclusion: High elevation of the leg after ankle fractures did not show a significant difference from low elevation in regard to leg swelling, pain, and function. Furthermore, high leg elevation resulted in discomfort during the postoperative period. Thus, low elevation with a pillow is enough for acute ankle fracture patients with little discomfort and satisfactory swelling reduction.

  • The narrow interal grid is effective in accuracy, but it is not able to make a densely grided sample, so that smoothing is requared. In digital elevation models, an application of the finite elements method is effective to smooth the undesired noise which is generated in aquisition of elevation data. And this is one of the simple and direct method to solve the problem for discontinuity of terrain. Therefore, the finite elements method is applied to study. In digital elevation model by appling the finite element, smoothing is affected by the height weight. In this study, the relation equation between elevation weight and standard deviation of smoothing was obstained as Y = 1900625 $X^4-312987.6$ $X^3+20330.72$ $X^2-578.6029$ X+12.63772 and from this function, Optimum elevation weight is 0.05.

  • Purpose: The purpose of this study was to compare the intramuscular activation of the scapular stabilizing muscles and the upper trapezius/middle serratus anterior (UT/MSA) ratios during shrug exercise and proprioceptive neuromuscular facilitation (PNF) scapular pattern exercise. Methods: The participants of this study were 13 young adult men who voluntarily consented to participate in this experiment after listening to its purpose and methods. All participants were instructed on maximal voluntary isometric contraction and scapular exercises. The intramuscular activation of the upper trapezius (UT), lower trapezius (LT), middle serratus anterior (MSA), and lower serratus anterior (LSA) muscles while performing scapular exercises in a side-lying position were measured using surface electromyography. To analyze the muscle activation and UT/MSA ratio between the two exercises, a one-way repeated ANOVA was performed. Post-hoc analyses were conducted using Tukey's multiple comparison and analysis. Hamstring flexibility for each group was measured by a passive straight leg raising test. Results: The shrug exercise showed significantly higher UT activation compared to PNF anterior elevation and posterior elevation scapular patterns. The PNF scapular anterior elevation pattern showed significantly higher serratus anterior activation than the shrug exercise. Additionally, the UT/MSA ratios were significantly lower in the PNF scapular anterior elevation pattern than in the two exercises. Conclusion: Although shrug exercise was effective for strengthening UT, the PNF scapular anterior elevation pattern may be effective for strengthening MSA and improving the UT/MSA ratio.

  • Background: The purpose of this study was to investigate the effect of structured cryotherapy on edema of patients who had a total knee arthroplasty (TKA). Methods: The subjects were 58 patients who were diagnosed with osteoarthritis and had total knee arthroplasty in D hospital. In total, 29 people were in the leg elevation cryotherapy group (LECTG), 29 people were in the control group (CTG). After TKA, the patients' swelling on post operation days (POD) 3 were checked. After the post OP checking, LECTG was treated with cryotherapy with leg elevation for 12 days but CTG was cryo therapy with sit on chair. Results: Swelling show significant difference within the group (p<.05), but did not show signigicant difference between groups (p>.05). Conclusions: Base on the results, it was found the cryo therapy of $-78^{\circ}C$ improved swelling after TKA. Accordingly, it is thought that cryo therapy of $-78^{\circ}C$ has positive effect on swelling in the process of recovery after operation. but It did not approve that the leg elevation was even more effective. For this study, the reserch developed to enhance the effectiveness of the cryotherapy, would make it possible to apply to an effective cryotherapy posture.

  • In order to spatially interpolate the near-surface temperature (Ta) values, satellite and reanalysis methods were used from previous studies. Accuracy of reanalysis Ta was generally better than that of satellite-based Ta, but spatial resolution of reanalysis Ta was large to use at local scale studies. Our purpose is to evaluate accuracy of reanalysis Ta and satellite-based Ta according to elevation from April 2011 to March 2012 in Northeast Asia that includes various topographic features. In this study, we used reanalysis data that is ERA-Interim produced by European Centre for Medium-Range Weather Forecasts (ECMWF), and estimated satellite-based Ta using Digital Elevation Meter (DEM), Normalized Difference Vegetation Index (NDVI), difference between brightness temperature of $11{\mu}m$ and $12{\mu}m$, and Land Surface Temperature (LST) data. The DEM data was used as auxiliary data, and observed Ta at 470 meteorological stations was used in order to evaluate accuracy. We confirmed that the accuracy of satellite-based Ta was less accurate than that of ERA-Interim Ta for total data. Results of analyzing according to elevation that was divided nine cases, ERA-Interim Ta showed higher accurate than satellite-based Ta at the low elevation (less than 500 m). However, satellite-based Ta was more accurate than ERA-Interim Ta at the higher elevation from 500 to 3500 m. Also, the width of the upper and lower quartile appeared largely from 2500 to 3500 m. It is clear from these results that ERA-Interim Ta do not consider elevation because of large spatial resolution. Therefore, satellite-based Ta was more effective than ERA-Interim Ta in the regions that is range from 500 m to 3500 m, and satellite-based Ta was recommended at a region of above 2500 m.

  • This paper presents a methodology for the calculation of effective rainfall by the SCS method using 3-dimensional digital elevation map and a Triangular Irregular Network module. The effective rainfall is calculated by taking into the increases of the runoff curve number(2%, 3%) due to the 10% increases of the slope of hillside, and the result indicate that the effective rainfall varies 5.0%∼12.0% with the storm events. It is demonstrated that in case of using the SCS method for the calculation of effective rainfall in the mountainous watershed with great elevation difference, the methodology taking into the slope of hillside is more viable.
