This study was carried out by using questionnaires with 200 general doctors serving as the director of health subcenter in Kyongsangbuk-do Province as of January 1995. The results are summarized as follows. It was shown that the general characteristics consisted of 53 directors in the lst year(26.5%), 85 in the 2nd year(42.5%) and 62 in the 3rd year(31.0%). The percentage spent on their medical service showed that 73.0% of those directors spent more than 90% on their medical service. Based on their general service attitiude, 0% answered that the director of the health subcenter completes the given duties as the director, and 24.5% did that the director has the sense of responsibility and duty. Multiple answers concerning inconvenience and difficulties of the health subcenter director showed that less monthly salary accounted for 75.5%, no administrative power for 50.0%, insufficient medical instruments for 35.5%, insufficient budget for 30.0%, respect. In conclusion, in order for the health subcenter to meet the function as the primary medical clinic, it is required to arange the plans to inspire the public health doctors' service desire to that they can give the medical service as good as the private primary medical clinics, to convert existing concept of the public health doctors' placement in Myon administrative district into new concept in Gun by breaking from a uniform placement, and to consider an intensive placement according to the relevant projects so that preventive health activities can be planned and carried out.

Purpose - The purpose of this study is to discuss problems and propose the direction of the current international university placement program in the country by deriving the concept of and developing questionnaires for 'service satisfaction'. Research design, data, and methodology -The SERVQUAL scale was used to measure the quality of services. In this study reliability, empathy, and assurance are used to measure the quality of the international university placement system, considering the characteristics of the education environment. The survey data is based on responses from 280 students who either have completed the international university placement system and currently studying abroad, or are studying the domestic part of the program. Cronbach's Alpha value was calculated. To verify the hypothesis, the multiple regression analysis was conducted. Results - According to the study, the satisfaction rate of the domestic learning process is heavily relied on reliability and empathy; particularly empathy on the curriculum of the international placement program. The study also found that to make students to feel a high sense of achievement, the satisfaction rate is a priority which should be improved. Conclusions - The results from the analysis of the hypothesis shows that the satisfaction rate of students who are taking the domestic part of the international university placement program should be increased.

Thoracic pedicle screw fixation techniques are still controversial for thoracic deformities because of possible complications including neurologic deficit. Methods to aid the surgeon in appropriate screw placement have included the use of intraoperative fluoroscopy and/or radiography as well as image-guided techniques. We describe our technique for free hand pedicle screw placement in the thoracic spine without any radiographic guidance and present the results of pedicle screw placement analyzed by computed tomographic scan in two human cadavers. This free hand technique of thoracic pedicle screw placement performed in a step-wise, consistent, and compulsive manner is an accurate, reliable, and safe method of insertion to treat a variety of spinal disorders, including spinal deformity.

Knowledge of the relationship between the hip and spine is essential in the effort to minimize instability and improve outcomes following total hip arthroplasty (THA). A detailed yet straightforward preoperative imaging workup can provide valuable information on pelvic positioning, which may be helpful for optimum placement of the acetabular cup. For a streamlined preoperative assessment of THA candidates, classification systems with a capacity for providing a more personalized approach to performance of THA have been introduced. Familiarity with these systems and their clinical application is important in the effort to optimize component placement and reduce the risk of instability. Looking ahead, the principles of the hip-spine relationship are being integrated using emerging innovative technologies, promising further streamlining of the evaluation process.

The structural health monitoring (SHM) benchmark study on optimal sensor placement problem for the instrumented Canton Tower has been launched. It follows the success of the modal identification and model updating for the Canton Tower in the previous benchmark study, and focuses on the optimal placement of vibration sensors (accelerometers) in the interest of bettering the SHM system. In this paper, the sensor placement problem for the Canton Tower and the benchmark model for this study are first detailed. Then an information entropy based sensor placement method with the purpose of damage detection is proposed and applied to the benchmark problem. The procedure that will be implemented for structural damage detection using the data obtained from the optimal sensor placement strategy is introduced and the information on structural damage is specified. The information entropy based method is applied to measure the uncertainties throughout the damage detection process with the use of the obtained data. Accordingly, a multi-objective optimal problem in terms of sensor placement is formulated. The optimal solution is determined as the one that provides equally most informative data for all objectives, and thus the data obtained is most informative for structural damage detection. To validate the effectiveness of the optimally determined sensor placement, damage detection is performed on different damage scenarios of the benchmark model using the noise-free and noise-corrupted measured information, respectively. The results show that in comparison with the existing in-service sensor deployment on the structure, the optimally determined one is capable of further enhancing the capability of damage detection.

High Altitude Platform (HAP) based networks deploy network infrastructures of Mobile Base Station (MBS) in a form of Unmanned Aerial Vehicle (UAV) at stratosphere in order to build network configuration. The ultimate goal of HAP based network is a wireless network service for wide area by deploying multiple MBS for such area. In this paper we assume multiple UAVs over designated area and solve the MBS placement and coverage problem by clustering the mobile ground nodes. For this study we assumed area around Cheju island and nearby naval area where multiple mobile and fixed nodes are deployed and requires HAP based networking service. By simulation, visual results of stratospheric MBS placement have been presented. These results include clustering, MBS placement and coverage as well as dynamic reclustering according to the movement of mobile ground nodes.
