Clinial effect of Vacuum Sealing drainage combined with antibiotic perfusion in the treatment of soft tissue defect of foot.
Hainan Medical Journal, 2013Co-Authors: Yang YongAbstract:Objective To observe the clinical effect of Vacuum Sealing drainage combined with antibiotic perfusion in the treatment of soft tissue defect of foot. Methods Vacuum Sealing drainage combined with antibiotic perfusion was applied to treat 18 patients with soft tissue defect in foot. The growing status of the wound granulation was observed, the key points of treatment were summarized, and the corresponding measures were proposed. Results The patients' wound granulation grew well. Free skin grafts were performed to repair the wound. The recovery was satisfactory. Conclusion Vacuum Sealing drainage combined with antibiotic perfusion can further reduce the infection rate and promote wound healing, which is an effective way to treat soft tissue defect in foot. Good grasping of the key technique points and treatment details would improve the curative rate.

Clinical Observation on Vacuum Sealing Technique for Chronic Wound
Chinese Journal of General Practice, 2013Co-Authors: Wang Ling-fenAbstract:Objective To analysis the clinical efficacy of Vacuum Sealing technique in treating chronic wounds.Methods Total 100 patients with chronic refractory wounds from 2008 to 2011 were selected as the object cases,and were randomly divided into observation group and control group with 50 cases in each group.The therapeutic efficacy,pain and depressive mood scores of patients in both groups were compared.Results The therapeutic efficacy in the observation group was better than that in the control group(P0.05),and the pain score and depression score was significantly lower than that in control group(P0.05).Conclusion The Vacuum Sealing technique can effectively promote the healing of patients,relieve the pain of the patient,and is worth popularizing.

ICCD Observation on Discharge Characteristics in AC Plasma Display Panel Prepared by Vacuum Sealing Process
IEICE Transactions on Electronics, 2009Co-Authors: Choon-sang Park, Heung-sik TaeAbstract:The Vacuum Sealing process with a base Vacuum of 10-5 Torr is adopted to minimize the residual impurity gas. The address and sustain discharges in the 42-in PDP prepared by the Vacuum-Sealing process are observed by using the ICCD. As a result, the ICCD observation illustrates that thanks to the reduction of the impurity level by the Vacuum-Sealing process, the surface and plate-gap discharges are initiated and extinguished very fast and the corresponding IR emissions are also intensified.

A Study on MgO Characteristics of AC Plasma Display Panel Fabricated by Vacuum Sealing Method
Molecular Crystals and Liquid Crystals, 2009Co-Authors: Choon-sang Park, Heung-sik Tae, Young-kuk Kwon, Eun Gi HeoAbstract:In this paper, the Vacuum Sealing method to enhance a base Vacuum level was adopted, and the resultant changes in the MgO characteristics, such as firing voltage, MgO sputtering rate, MgO hardness, and photoluminescence, were examined in comparison with those in the conventional Sealing method in the 42-in. AC-PDP with a high Xe (15%) content. The 42-in. panel fabricated by the Vacuum Sealing method caused the changes in the MgO characteristics, such as firing voltage, MgO sputtering rate, MgO hardness, and photoluminescence, which are caused by an increase in the oxygen vacancy of the MgO layer.

A Study on Temporal Dark Image Sticking in AC-PDP Using Vacuum-Sealing Method
IEICE Transactions on Electronics, 2009Co-Authors: Choon-sang Park, Heung-sik TaeAbstract:Minimizing the residual impurity gases is a key factor for reducing temporal dark image sticking. Therefore, this paper uses a Vacuum-Sealing method that minimizes the residual impurity gases by enhancing the base Vacuum level, and the resultant change in temporal dark image sticking is then examined in comparison to that with the conventional Sealing method using 42-in. ac-PDPs with a high Xe (11%) content. As a result of monitoring the difference in the display luminance, infrared emission, and perceived luminance between the cells with and without temporal dark image sticking, the Vacuum-Sealing method is demonstrated to reduce temporal dark image sticking by decreasing the residual impurity gases and increasing the oxygen vacancy in the MgO layer. Furthermore, the use of a modified driving waveform along with the Vacuum-Sealing method is even more effective in reducing temporal dark image sticking.

Discharge Characteristics of AC Plasma Display Panel Prepared Using Vacuum Sealing Method
IEEE Transactions on Plasma Science, 2008Co-Authors: Choon-sang Park, Heung-sik Tae, Young-kuk Kwon, Eun Gi HeoAbstract:The base Vacuum level achieved before loading the discharge gas is known to be an important parameter that affects both the address and sustain discharge characteristics in an AC plasma display panel (PDP), as a higher base Vacuum level improves the discharge characteristics. Accordingly, the Vacuum Sealing method, which can enhance the base Vacuum level, is adopted to enhance the MgO characteristics by reducing any residual gas impurity. The resulting changes in the address and sustain discharge characteristics, including the secondary electron coefficient, firing voltage, and dynamic voltage margin, are then compared with the results when using conventional atmospheric-pressure Sealing for a 42-in ac PDP with a high Xe (11%) content. The Vacuum Sealing method was found to improve the secondary electron emission coefficient, lower the firing voltage, particularly under MgO cathode conditions, and increase the dynamic voltage margin. However, the Vacuum Sealing was also found to deteriorate the visible transmittance of the dielectric layer in the front panel. Nonetheless, the Vacuum Sealing process enabled the use of a higher Xe content, which is up to 17%, under a stable dynamic margin voltage, thereby improving both the luminance and luminous efficiencies of the AC PDP.

Prevention of Boundary Image Sticking in an AC Plasma Display Panel Using a Vacuum Sealing Process
IEEE Transactions on Electron Devices, 2008Co-Authors: Choon-sang Park, Heung-sik Tae, Young-kuk Kwon, Eun Gi Heo, Byung-hak LeeAbstract:Boundary image sticking can be inherently prevented in an ac plasma display panel fabricated using a Vacuum Sealing process. The results indicate that residual impurities, such as nitrogen or oxygen, are essentially related to the production of boundary image sticking. When checking the production of boundary image sticking in a test panel fabricated using a or an flow during the Vacuum Sealing process, no boundary image sticking appeared in the case of a flow, whereas boundary image sticking was produced with an flow, although the test panel was fabricated using a Vacuum Sealing process. Consequently, reducing the residual impurity, particularly oxygen, based on a Vacuum Sealing process can inherently prevent boundary image sticking.
