Purpose : The information of mental health facilities in Korean law is so unclear that people hardly enable to understand what sort of proper mental health service is prepared for them. Futhermore, there is not enough regulation and standard to classify each type of facilities in the law. Therefore the purpose of this study is to provide data on the basis for classification and facility standards by analysing Korean law and policies. Methods : This study was conducted by a research on law and regulation of mental health facility. Results : The result of this study can be summarized into three points. The first one, current law and policy do not reflect a change in community mental health services paradigm. The second one, the classified facility should be designed to fit the community mental health services. The third one, overall, it requires more detailed guidelines to enhance the quality of mental health services. Besides, the treatment as well as the function of the prevention and rehabilitation are necessary criteria that can also be enhanced. Implications : This study looked at the classification and facility standard of mental health facility by the change in community mental health services paradigm. Forward according to these changes, there is a need for specific guidelines for mental health facility.

Digital Contents are increasing the modification of the contents by individual user and the modified or copied contents are simply distributed though the ultrahigh speed internet and the negative pervasive effect on the contents market is increasing. The solutions for copyright protection from illegally distributing contents are developing by various standardization groups and contents manufacturers and its commercia use is partly practiced. The MPEG was developing the IPMP technique to apply existed MPEG standards as a way of digital contents protection. However, as these IPMP techniques did not provide a satisfactory function for contents protection, the DMP standard was suggested as an alternative plan. In this paper, the system is designed and materialized to apply the TooIPack concept of DMP which ensure the interoperability of DRM system. With this paper, it is expected that the practical use and the possibility of the DMP standard in the DRM market would be verified and DMP standard may presents as a reference model for more systematic standardization operations.

Recently, many researches have been conducted to solve data heterogeneity as a way for data integration. The elements of the system that we suggest are an XMDR wrapper and XMDR Repository. XMDR wrapper solves the heterogeneity of the existing system by creating the interface based on the standard information of XMDR, and performing the inter-conversion between global XMDR query and local query using mapping data on standard information and local schema. XMDR Repository are composed of XMDR which manages the mapping data on standard information and local schema, and of Proxy DB which saves the accomplished results. With XMDR wrapper and XMDR Repository, users can use the same interface, and they need not conduct repeated queries since XMDR wrapper not only solves the heterogeneity of the schema using the meta-semantic ontology of XMDR, but also considers the heterogeneity accompanying the meaning of the value through instance semantic ontology. Therefore, in this paper we suggest the grid wrapper for the solution of data heterogeneity and efficient data integration.

Owing to rapid advancements of the mobile computing technologies and the performance of mobile device recently, the data synchronization techniques between severs and mobile clients are getting more and more important. OMA also proposes and recommends standard synchronization methods to use SyncML. However, the feasible data in the method are limited to normal document data, scheduler data, etc. This paper a standard framework based on SyncML. We call it SCGFG. The SCGFG is able to synchronize not only the above data but also GIS data which is very useful in mobile applications. It applies GML, international GIS standard, to the synchronization. By means of using XML, it is also able to resolve the serious problem that is the increase of data volume occurred by SyncML and GML. efficiently. It is highly expected to be useful in the smart synchronization of GIS data among several servers and mobile clients.

Recently, as the interest in power saving increases with the development of IoT technology, research on power saving of smart devices, which are being miniaturized, is being actively conducted. In particular, due to the diversification of IoT-based smart devices and the increase in personal penetration rate, the issue of standby power even when not in use is increasing. However, there is a drawback of physically unplugging the outlet or turning off the power in order to substantially reduce standby power. Since Zigbee is used instead of the existing IP, it is necessary to change to the IoT standard protocol based on the Internet network. Therefore, this paper designed and implemented the standby power saving system applying CoAP, the IoT standard protocol, to the existing Zigbee technology. Existing systems and evaluations confirmed that the average standby power of about 8.4Wh was reduced.

In the case of river facilities, the management of this information differs depending on national and regional rivers, therefore, there is no integrated management in place. There is concern about the loss of facility information owing to the insufficient accumulation of information during their design and construction stages. Additionally, as a result, the utilization level of facility information during the maintenance and operation stages is insufficient. To ensure effective maintenance and operation of river facilities, it is necessary to secure data consistency and increase efficiency by organizing facility information according to a standardized classification system. This study proposes a strategy for implementing the BIM standard classification system in the river sector, considering facility characteristics. The goal is to introduce a BIM information model for 3D-based river facilities, and enable efficient maintenance and operation conversion.

More than 25% of software copyright evaluations commissioned to the Korea Copyright Commission are software completeness-defective evaluations. Most of the existing software completeness-defective evaluation cases were made to ensure that the requirements contained in the contract or customer's desired requirements were implemented and able to run, limited to the functionality of the software. This paper proposes a more systematic and reasonable maturity-correction technique to meet software completeness definitions. The ISO / IEC 9241.10 standard is a design standard for improving software quality. The ISO / IEC 9241.10 standard specifies seven items that must be complied with and requires functional integrity for work and operational integrity for work efficiency. The software completeness-defective methodology presented in this paper complements the existing function's implementation-functioning methodology with completeness evaluation on the quality of software.

The 16-port feed waveguide array with inductive walls analyzed by Galerkin's method of moments are proposed for the DBS reception system mounted on vehicle. First of all, in order to verify the validity of electromagnetic analysis and design for a $\pi$-junction feed waveguide, it is designed and fabricated at DBS band. The measurement results of a $\pi$-junction feed waveguide agree well with the theoretical ones. Based on this design method, an array design for WR-90 standard waveguide is conducted. Since the width of a $\pi$-junction feed WR-90 standard waveguide is larger than a guided wave length in an array design, the difference of amplitude and phase of 8-port array are calculated 2.3 dB and 62 degrees, respectively. The bandwidth with return loss of -20 dB below is about 220 MHz and it doesn't satisfy DBS band. To solve this problem, we propose a novel design that the width of a $\pi$-junction feed waveguide equals to a guided wave length. By the proposed novel design for 8-port feed waveguide array, the difference of amplitude and phase are decreased 1 dB and 13 degrees, respectively. The broad bandwidth of 700 MHz is also realized. The size of 16-port waveguide away compared with WR-90 array is reduced about 10 cm. The measured antenna gain for the fabricated 16-port feed waveguide array is observed 24 dBi above at DBS band.

The amount of ventilation required in making the tunnel ventilation plan is an important factor for determining the capacity of the ventilation system. The amount of pollutant emission for each type of vehicle (basic emission amount for the design of ventilation volume) for estimating the required ventilation amount is based on the 'Standard for Allowing the Emission for the car manufacturing', proposed by Ministry of Environment. However, in 2013, the Ministry of Environment announced the 'Regulations on the calculation method of total emissions from vehicles' as a regulation for calculating the pollutants emitted from vehicles. In this regulation, there are the 'Emission factors for each type of vehicle'. Therefore, it is necessary to review the application of the Regulation to the estimation of the required ventilation volume for the road tunnel. In this study, the influence of the strengthened emission regulation in 2015 caused by the case of manipulation of emission volume for the diesel vehicle on the calculation of the required ventilation volume in the road tunnel has been checked. In addition, in this study, the required ventilation volume calculated according to the Standard for Allowing the Emission for the car manufacturing revised by Ministry of Environment and "Emission factors for each type of vehicle" and that calculated according to the EURO emission standard were compared for analysis. This study has implications that it provides the basic design data for calculating the reasonable ventilation capacity of the ventilation system based on the ground for calculating the required ventilation volume.
