Recurrence is the most common complication after shoulder instability surgery, and the main causes of the postoperative recurrence of instability are trauma, misdiagnosis, and technical errors. The risk factors of recurrence may be classified as patient related, anatomical or technical. Causes of failure should be thoroughly evaluated by meticulous history taking, physical examination, and imaging studies, and followed by proper treatment of pathologic lesions. Nonoperative treatment should be considered initially in cases of recurred instability after shoulder instability surgery, but if this fails, repeated recurrence is prevented by performing appropriate anatomical reconstruction of ruptured Bankart lesions, capsular laxities, glenoid deficiencies and humeral head bone defects.

Since January 2009, Seoul Metro Government(SMG) is operating own Network RTK Systems connecting four(4) GNSS Reference Stations which are installed inside Seoul Metro City area. SMG is currently providing VRS data service via wireless internet for Network-RTK and RINEX data observed from GNSS Reference Stations. This paper will discuss utilization of data available from SMG Network-RTK System for various applications, and present the test results on practicalities of Virtual RINEX data. For the utilization of data available from SMG Network- RTK system, 1)NTRIP data delivery of GNSS realtime observables streaming and converting to RINEX at receiving side, 2) monitoring deformation of bulky structures using GNSS observation were discussed. In addition to those discussion, 3) broadcasting VRS correction data for job site via radio modem after acquiring such correction data on-line using NTRIP based GNSS Internet Radio from SMG Network-RTK System were introduced. For the test results on practicalities of Virtual RINEX data, 1) the post-processing results of the GNSS observation data on a certain point with GNSS Reference Station data have been compared to the post-processing results of Virtual RINEX data on the same point generated from SMG Network-RTK System, and 2) VRS RTK positioning results for a certain point and post-processing results of Virtual RINEX data for the point were compared. The results showed only a few mm difference, and the high possibility for using Virtual RINEX data for post-processing applications.

It is necessary to evaluate methods for reasonable diagnosis for public transportation. However, previous studies have the problems in evaluation ground and propriety. Therefore, this research develop the method and equation for evaluating bus route considering interregional equity and route doubleness. This study developed in bus route evaluation method using Seoul bus Zone, and included the result of evaluation test using 199 route Seoul trunk bus (blue bus). Zone (0) (Jongno-gu, Jung-gu and Yongsan-gu) has the highest score in Evaluation result. Also this zone has good bus route, so it is easy to move to other Zone. It is possible to change and add the bus route to use the equation in this study, considering interregional equity.

The objective of this research is to analyze geographical distribution of Korean dental hygienists to provide the geographical basis of supply-side policy for dental hygienists from the perspective of dental geography by using Geographic Information System (GIS) in which the choropleth map has been regarded as the most popular method. The present report is highly meaningful for the policy of dental hygienist on the supply side of dental care market. The data used in the article derive from the statistics-associated portal site provided by Korean government. It includes the statistics on general population, the regional numbers of dental hygiene students, county-based numbers of registered dental hygienists, dentists, and dental clinics and hospitals. Several maps are created by investigating these statistical data with GIS. This study is focused on the comparative analysis between entrants to the department of dental hygiene, registered acting dental hygienists and dentists in terms of county-based distribution per its population. The main result demonstrates that whereas about half of dental hygienists and dentists are respectively concentrated in Seoul and Gyung-gi, just one-fifth of entrants to the department of dental hygiene in the Seoul-metropolitan area. From the perspective of the supply-side policy of dental hygienists, the research argues that the creation or expansion of the department of dental hygiene does not directly meet social need for dental care services.

Now In Seoul, about 75,000 CCTVs are installed in 25 district offices. Each ward office in Seoul has built a control center for CCTV control and is building information such as people, vehicle types, license plate recognition and color classification into big data through 24-hour artificial intelligence intelligent image analysis. Seoul Metropolitan Government has signed MOUs with the Ministry of Land, Infrastructure and Transport, the National Police Agency, the Fire Service, the Ministry of Justice, and the military base to enable rapid response to emergency/emergency situations. In other words, we are building a smart city that is safe and can prevent disasters by providing CCTV images of each ward office. In this paper, the CCTV image is designed to extract the characteristics of the vehicle and personnel when an incident occurs through artificial intelligence, and based on this, predict the escape route and enable continuous tracking. It is designed so that the AI automatically selects and displays the CCTV image of the route. It is designed to expand the smart city integration platform by providing image information and extracted information to the adjacent ward office when the escape route of a person or vehicle related to an incident is expected to an area other than the relevant jurisdiction. This paper will contribute as basic data to the development of smart city integrated platform research.

The administration of Korean local governments in charge of natural disaster management and manmade disaster management has been completely or partially integrated to the fire fighting headquarters since 1990's. Therefore the relationship between the fire fighters and the regular officers has been more important. So in this study, I made a questionnaire about management ability, rescue activities, disaster, business efficiency of the disaster management organization. And then I did a question research to the comparison analysis of recognition between fire fighter and regular officers of Seoul disaster management organization. As a result of the comparative analysis of understanding, there is a meaningful difference among facilities of management ability, man-made disaster of disaster, business cooperation and business connection of business efficiency. Through the comparison analysis of recognition, I tried to present the improvement of Seoul disaster management organization.

The purpose of this study is to analyze the form and content of the Ordinance on Job Support for the Elderly, and to verify whether the Ordinance has formal validity and effectiveness. For this purpose, the 13 local ordinances of the municipal governments in Seoul were selected for analysis and the contents and composition of each ordinance were analyzed. As a result of the analysis, no major difference was found in the main form of the regulations such as the purpose of enactment of ordinances and contents of business. However, the scope of the policy application and the provision related to the delivery system were confirmed to be different by each regulation. In particular, residents' rights to services did not exist in all ordinances, and the obligation of local governors to provide jobs for the elderly was lacking in specificity and needed improvement. In terms of effectiveness, there are no provisions related to the delivery system or the mandatory nature of the regulations. Based on this analysis, this study proposed the directions of improvement and supplement of the ordinances.

Efforts to establish a joint preservation facility for library collection are being discussed by some of regional representative libraries recently. In order for the efficient management and preservation of public library materials and to secure the space necessary for applying new services, there is a high demand for a cooperative shared storage for public libraries. The construction of a cooperative shared storage for public libraries is to minimize the cost of expanding the preservation space for each public library and to provide a pleasant service environment by separating the low-use materials stored in the library. Accordingly, discussions on the construction of a cooperative shared storage for public libraries are being initiated by some representative libraries. This study, in this regard, tried to propose a plan to build a cooperative shared storage for public libraries by a Seoul Metropolitan Library. To this end, it surveyed the estimate size of the collections of public libraries in Seoul and, based on this, proposed the size and strategies for the facility.
