Purpose: Most of postoperative patients experience pain, state anxiety and sleep disturbance. These problems negatively influence the recovery of postoperative patients. So alleviating these problems has been one of the nurses' central roles. The purpose of this study was to examine the effects of back massage on pain, state anxiety and quality of sleep of postoperative gastrectomy patients. Methods: A non-synchronized non-equivalent control group pre and post-test design was used. The research instruments used in this study were the Numerical Rating Scale (NRS) for pain, the State-Anxiety Inventory (STAI) for anxiety and the Verran and Synder-Halpern scale for quality of sleep. The subjects were patients admitted to a university hospital located in D city. Twenty-nine patients in the experimental group had a 10 minute manual back massage stimulation for 5 days from the 1st day to the 5th day after their operation, and 25 patients in the control group did not. Results: The degree of pain was significantly reduced according to post operation day and quality of sleep was significantly increased. However state anxiety was not significantly reduced. Conclusion: Back massage is a partially effective nursing intervention for postoperative patients with gastrectomy who experience pain and sleep disturbance.

This case study refers to turbine-generator with retrofitted turbine rotor. Vibration problem occurring after the retrofit was mainly due to high vibration from exciter side. However, repeated test run and operation during scheduled maintenance caused high vibration from generator bearing, and post-overhaul test run before turbine vibration correction caused oil whip on the bearing. This case study shows how to analyze vibration condition of high turbine generator vibration detected during the post-overhaul test run and vibration condition of offline and online data to reflect it on establishing maintenance schedule and overhaul correction procedure. Vibration data could be acquired during steady load operation or even with varying speed and load. Each data is important for machinery condition evaluation. This case study shows that the vibration data during extreme condition is the key factor in analysis, which helps to find the machinery problem.

It is essential to apply compression bands or pressure garments that can stabilize the breast implants and breast shape as well as help shape the breast to the desired shape immediately after breast augmentation surgery. It is necessary to study the compression garment which is able to properly cover a deformed breast due to the operation and shape it as a beautiful breast. The subjects of the study were 6 women who experienced breast augmentation surgery with an under bust size of 70 or 75, cup size of C cup with a hemispherical and conical shape. We analyzed the dissatisfaction and satisfaction factors through the evaluation of the 4 types of commercial compression garments and developed the new functional post-operative bra which can be worn immediately after the operation according to the breast characteristics of breast augmentation patients. We have developed new bra patterns; a front opening type garment with wings and a band type garment both sides that allow the band to be pressed from the front center. The comparative wearing evaluation indicated that the superiority of the new compression garments also provided a higher the satisfaction of the newly developed bra (front adjustable style) than a commercial band.

This sutdy aimed at examining the effect of lingual frenectomy on phonation & tongue movement. Almost the patient visiting to department of oral & maxillofacial surgery for the treatment of tongue tie always complain the speech problem. Many operation was performed according to this problem. But the objective evaluation of the speech change have been deficient. The experimental group was 25 adult males. Fourteen Korean consonants & after Korean vowels was combined and seventy sound was made for speech analysis. Before & after lingual frenectomy, the speech of the above mentioned group was recorded and then analysed by the Speech Workstation computer software. And before & after operation, the lingual frenum & tongue protrusion amount vas measured. The results were as follows : 1. The pre-operative length of lingual frenum was inverse proportion with the pre-operative length of the protrusive tongue. 2. The average difference between pre & post-operative length of the protrusive tongue was about 23 mm. 3. In the comparison of consonant continuing time change, fricative consonant(r, s, h) was increased post-operatively. 4. In the comparison of the vowel frequency formant change, the "i"and "u" sound vas reliably changed. 5. There was no reliable speech changes on the other sounds.

Purpose: Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. Materials and Methods: Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. Results: Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). Conclusions: Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

This study compares the results of environmental impact assessment with the results of post-environmental investigation, using the case of Taean thermal power plant construction. The atmospheric and water qualities were not greatly changed before and after the construction of the power plant. However, the site of the highest concentration predicted by the atmospheric quality modeling in environmental impact assessment was different from that after operation of 4 power plants. There was also a difference in the diffusion range of thermal discharge water between the measured result(1km) and the predicted value(1.5km) with the model. Thus, environmental impact evaluation should be based on long-term (more than a year) environmental monitoring data. For the modeling of atmospheric quality and numerical thermal discharge water diffusion, appropriate models for each plant should be selected and the numerical modeling should be accompanied by computer simulation, wind tunnel test, etc. Moreover, environmental evaluation should focus more on the degree of impact on surroundings than the prediction of changes in surroundings caused by operation of plants.

Background Locoregional stem cell delivery is very important for increasing the efficiency of cell therapy. Amnisite BA (Amnisite) is a freeze-dried amniotic membrane harvested from bovine placenta. The objective of this study was to investigate the retention of cells of the stromal vascular fraction (SVF) on Amnisite and to determine the effects of cell-loaded Amnisite in a porcine radiation-induced chronic wound model. Methods Initially, experiments were conducted to find the most suitable hydration and incubation conditions for the attachment of SVF cells extracted from pig fat to Amnisite. Before seeding, SVFs were labeled with PKH67. The SVF cell-loaded Amnisite (group S), Amnisite only (group A), and polyurethane foam (group C) were applied to treat radiation-induced chronic wounds in a porcine model. Biopsy was performed at 10, 14, and 21 days post-operation for histological analysis. Results Retaining the SVF on Amnisite required 30 minutes for hydration and 1 hour for incubation. A PKH67 fluorescence study showed that Amnisite successfully delivered the SVF to the wounds. In histological analysis, group S showed increased re-epithelialization and revascularization with decreased inflammation at 10 days post-operation. Conclusions SVFs had acceptable adherence on hydrated Amnisite, with successful cell delivery to a radiation-induced chronic wound model.
