The diagnosis and treatment plan for forming ideal occlusal plane in full mouth rehabilitation are difficult because each process is complicated and information exchange between dentist and technician is subjective. The OP finder^® system simplifies this process and helps to deliver more objective and accurate information. In this case, full mouth rehabilitation was performed using OP finder^® system for patients with old bad fixed prosthesis and severely worn mandibular teeth, and reported that the result of proper occlusal plane setting and masticatory function recovery was obtained.

Many message logging and checkpointing schemes are proposed for fault tolerance in distributed systems in which nodes communicate by message passing. Most researches for recoverable distributed shared memory (DSM) also adopt similar schemes used in message passing systems. However, schemes used in message passing systems are not always appropriate to be directly used in DSM systems because the two systems, message passing systems and DSM systems, have different natures (function shipping and data shipping). Many modified schemes have been proposed for DSM systems to resolve these differences. In this paper, an object oriented approach is proposed for recoverable DSM. We present a new dependency tracking scheme between pages instead of processes. Based on this scheme, we propose new checkpointing and recovery schemes that can reduce overhead to make DSM recoverable.

Purpose : We described how the training of non-dominant hand that applicates the activity effects on dominant hand. Method : From November 6th to December 2nd 2013, We randomly selected 18 people that don't have a damage of hand function and are in college of K in Busan. (cross stitch training group 9 people, control group 9 people) All participants agreed on the research after fully being aware of training procedures and spontaneously conducted. Each training was practiced for 40 minutes in once every second day. One researcher deals with three participants at silent environment. We used the study measurement, Purdue pegboard, to investigate the sharpness of hand. To investigate the advancement of hand function caused by cross stitch training, we practiced three times estimations of primary one before training, middle one after 2 weeks training, last one after four weeks training and obtained the following results. Result : First of all, We found that the group of hand training appeared to be advanced of dominant hand's sharpness depending on the training period more than the control group. Second, We found that the group of hand training appeared to be advanced of non-dominant hand's sharpness depending on the training period more than the control group. Third, We found that the group of hand training appeared to be advanced of both hand's sharpness depending on the training period more than the control group. Fourth, We found that the group of hand training appeared to be advanced of the assembling function sharpness depending on the training period more than the control group. Conclusion : Put the results of this research together, we found that non-dominant hand training that used the activity was of help to advance the function of dominant hand. So, we thinks that hand training might help the recovery of affected hand function to the person that have a problem of hand function like hemiplegia patient. It will be required to practice the further study targeting the person that have a problem of hand function like hemiplegia patient. We hope that this research will be apply to clinical occupational therapy.

Wind and flood damage caused by typhoons causes a lot of damage to the Korean Peninsula every year. In order to minimize damage, a preliminary analysis of damage estimation and evacuation routes is required for rapid decision-making. This study attempted to develop an analysis module that can provide necessary information according to the disaster stage. For use in the preparation stage, A function to check past typhoon routes and past damage information similar to typhoon routes heading north, a function to extract isolated dangerous areas, and a function to extract reservoir collapse areas were developed. For use in the early stages of response and recovery, a function to extract the expected flooding range considering the current flooding depth, a function to analyze expected damage information on population, buildings, farmland, and a function to provide evacuation information were included. In addition, an automated web map creation method was proposed to express the analysis results. The analysis function was developed and modularized based on Python open source, and the web display function was implemented based on JavaScript. The tools developed in this study are expected to be efficiently used for rapid decision-making in the early stages of monitoring against storm and flood damage.

Ischemic preconditioning is known to have protective effect on myocardial function at prolonged ischemic insult but the mechanism of the effect is not clearly known. The effect of the preconditioning on the global ischemia using cardioplegic solution is not well known. To evaluate the effect of global myocardial preconditioning on the functional recovery after cardioplegic arrest and two hours of hypothermic storage, we used the isolated rat heart and two hours cardioplegic arrest time at $0^{\circ}C$. In the experimental group(n=10), after baseline functional data was obtained, ischemic preconditioning was induced with 1 min of global normothermic ischemia for three times before the arrest period. In the control group(n=10), hearts underwent no ischemic precondi- tioning. After 2 hrs of cardioplegic arrest and storage in the $0^{\circ}C$ cardioplegic solution reperfusion was done and hemodynamic data were collected at post-reperfusion 20 min. Heart with ischemic preconditioning showed improved functional recovery at post reperfusion 20 min in peak developed pressure and dP/dT. In percent change of the peak pressure, preconditioning group showed 93.20$\pm$15.7% recovery rate compared to baseline data, and control group showed 67.3$\pm$15.6% recovery rate. In percent change of the dP/dT, control group showed 54.7$\pm$18.2% recovery rate and preconditioning group showed 78.1$\pm$15.1% recovery rate. Percent changes in heart rate and coronary flow showed no significant difference between two groups and there was no significant differences in amount of cardioplegic delivery between groups. Our data suggest ischemic preconditioning may have protective effect on recovery state after cardioplegic arrest and 2 hr ischemic storage of isolated rat heart and its mechanism is not related to the amount of the cardioplegic delivery amount.

Background: After general anesthesia, decrease of functional residual capacity and lung compliance, ventilation/perfusion imbalance, and transpulmonary shunting can provoke hypoxemia during postoperative periods. Diaphragmatic dysfunction may be the main cause of these physiological abnormalities. Thus, we evaluated the change of pulmonary function after general anesthesia according to the operative sites, which could suggest clinical course and critical period of respiratory care of postoperative patients. Method: Preoperative portable spirometric evaluation and arterial blood gas analysis were performed at sitting or most-sitting position just previous day of surgery. Pulmonary function tests were also as same condition from postoperative day 1 to day 5. Results: 1) For thoracic surgery, FEV1 and FVC were not recovered at day 5, but FEV1/FVC was not decreased. $PaCO_2$ was slightly elevated at postoperative one day. 2) After upper abdominal surgery, postoperative day 5 did not show the recovery of FEV1 and FVC, but mild hypoxemia was developed at postoperative day 1. 3) Pulmonary function was recovered as preoperative value at postoperative day 5 in lower abdominal operation, but mild hypoxemia was also noted at postoperative day 1. 4) Surgery of peripheral areas did not show significant pulmonary function change and hypoxemia and hypercapnia from postoperative day 1. Conclusion: Surgery involving diaphragm provoke significant postoperative pulmonary function change after day 5. For the operation of peripheral sites adequate respiratory care during operation and postoperative period within 24 hours could prevent patients from respiratory complication.

Purpose : This study aimed to investigate the effects of a digital pegboard training program with visual and auditory feedback on hand function and visual perception in stroke patients. Methods : Twenty two participants were randomly assigned to an experimental or control group. The experimental group received training using a digital pegboard training program with visual and auditory feedback (n=11), while traditional occupational therapy was administered to the control group (n=11). Hand function was assessed before and after the intervention using the Nine-Hole Peg Test and manual function test (MFT), while visual perception was assessed using the Motor-Free Visual Perception Test-3rd edition (MVPT-3). Results : Following the intervention, both the experimental and control groups showed significant improvements in performance in the Nine-Hole Peg Test and MVPT-3 (p<.05). The improvement on both tests was significantly greater in the experimental group than in the control group (p<.05). Conclusion : The results suggest that digital pegboard training with visual and auditory feedback may improve hand function and visual perception in stroke patients. Therefore, this intervention can be effective in occupational therapy to aid the recovery of stroke patients.

We have studied the effect and application of CST which is the function and disease of the autonomic nerve system based on recovery of flexibleness of the autonomic nerve. CST purpose to keep sustenance of human body by recovering joints have limitation of mobility and controlling autonomic nerve system by diminution tense of the sympathetic nerve. CST makes well flowing of CSF by pressure the fourth ventricle of the brain or relaxation of soft tissues of the base of a cranial bone. There is no result of studies about CST in Korea yet. It will bring a benefit if it prove the effect of CST in countries depend on drugs way high such as Korea. It needs positive approach and definite research for the improvement.

In the case of the trauma on the maxillofacial region occurred, we think that one of the most important thing is recovery of the function as well as reconstruction of the anatomical form. Especially, it has been that the structure of the surrounded temporomandibular joint has a great possibility to cause mouth opening limitation when a bit of displacement is caused. Therefore, in the case of the trauma on mid-face we think that we treat it after complete evaluate condition of soft and hard tissue surrounding the articular disc as well as fracture site. We report results of our study, since we obtained good results from our study concerning the refixation of the zygomatic arch, high condylectomy, coronoidectomy and myotomy for the patient being suffered from the arthrosis of the temporomandibular joint caused by insufficient fracture treatment of zygomatic arch and coronoid process.
