The cemetery areas which are occupied more than 1.0 percent of whole land of Korea have widened gradually but the reconnaissance is not being conducted for the cemetery investigation due to deficiencies for budget and manpower of the government. The aim of this study is to find a method to establish the lower cost GIS-based cemetery management system by using hand-held DGPS receiver and Mobile GIS software system for easy cemetery management. The results were evaluated and compared to the RTK GPS method. Since the Cemetery Management System shows every tomb's position on the high resolution satellite imagery with a cadastral data, the map helps to find the interesting places easily. Therefore the system data can be used for various purposes such as planning for land development, dealing with real estate as well as cemetery management.

Accidents of commuting vehicles for preschoolers continue to occur despite various safety policies from the government. In order to minimize such accidents, it is necessary to use both the vehicle-mounted safety commutation management software for the driver, and the mobile App to manage the safe schooling of the children that can inform such information to parents in time. In this paper, we describe the design and implementation of the safety management software architecture. The mobile application is designed for Android operating systems. It informs current driving information if the bus as well as the list of current boarded children. Teacher in the bus can manage exceptional cases such as riding child without RFID and unregistered temporary riders like grandparent for convenience and flexibility.

Given social problems of technology addiction such as games and mobile messenger services (MMSs), it have become important to understand theoretical mechanisms to generate technology addiction. In this vein, this study examined key antecedents of technology addiction in the MMS environment. We posit technology habit and user satisfaction as key predictors of technology addiction. In addition, the impacts of social interaction and flow on use's technology addition formation were investigated The research framework was tested by using survey data collected from 278 Kakaotalk users who have used more than 6 months. The analysis results found that both technology habit and user satisfaction play an important role in generating technology addiction in the MMS context. The findings of this study indicate that social interaction and flow significantly affects technology habit and user satisfaction. The analysis results help government and MMS providers establish policies or strategies to induce healthy MMS use.

The United States is responding to evolving cyberattacks through the Commercial Solutions for Classified Program (CSfC). Authorized safety evaluation and certification are being carried out so that US government agencies can quickly introduce civilian commercial security products into the national pavilion. Commercial security products registered in the CSfC process can be used by defense agencies through a rapid approval process. Defense agencies approve commercial security products without duplicate evaluation. Approved security products can reduce the time, cost, and cost of the approval process required to implement the defense information system. In this study, security control for 4 types of network security architecture MSC (Multi-Site Connectivity), MA (Mobile Access), Campus WLAN, and DAR (Data at Rest) proposed by the US National Security Agency (NSA) for introduction to national defense A detailed analysis was performed on the items.

The objective of present study was to develop a simultaneous determination method of 5 medical compounds, including beclomethasone, dexamethasone, prednisolone, ketoprofen, phenylbutazone in foods, using LC-MS/MS. To optimize MS analytical condition of 5 compounds, each parameter was established by MRM mode. The chromatographic separation was achieved on a C18 column successfully, with a mobile phase made up of A (0.1% formic acid) and B (0.1% formic acid in acetonitrile), at a flow rate of 0.3 mL/min for 17 min with a gradient elution. LOD and LOQ of 5 compounds were in the range of 0.40~4.60 ng/mL and 0.81~11.46 ng/mL, respectively. As a result of analyzing the three concentrations of the standard mixture added to blank samples, the results showed that the mean recovery rate of 5 compounds was in the range of 81.52~103.83%, and RSD (%) of Intra- and Inter-day assay were 0.52-10.45. Since relatively fine selectivity, accuracy and reproducibility were shown in this qualified experimental method, it could be utilized efficiently to investigating those 5 compounds to see if it is added to food products illegally.
