  • In the era of government 3.0, the availability of open government-owned public data and data sharing with the private sector are important. We surveyed the status of public data openness in the healthcare domain and of compliance with the standard open data format based on the "5 stars of linked data" model. We examined healthcare data on the Open Data Portal (https://www.data.go.kr). We also surveyed data on the websites of the public institutions and state administrative agencies that provided healthcare data on the Portal. In terms of data on the Portal, all public institutions except the National Medical Center, the Korea Institute of Science and Technology Information, and the Korea Environment Corporation were found to have provided data in the 3-stars format corresponding to the Public Data Open Standard Maintenance Guide. All data provided by state administrative agencies met the 3-stars format. Only 2 institutions (the Health Insurance Review & Assessment Service and the Korea Health Industry Development Institute) released data in the 3-stars format on their websites. Among the major state administrative agencies providing data on the Portal, none released data in the 3-stars format on their websites. Government-owned data should be provided in a standard format both on the Open Data Portal and on data-holders' websites to facilitate communication and collaboration. Considering the huge potential of linked healthcare data from a single national health insurance system, providing open data in compliance with the standard open format will promote the opening and sharing of public data.

  • The focus is moving from the problem of building data to the problem of accessing and efficient utilization of data fitting to the purpose of a user. A distributed technology and a standard of geodata and geoprocessing is needed to satisfy these needs. This paper suggests an implementation method of a standard interface defined by OpenGIS with CORBA which is a distributed object technology. A client can invoke Open API of the middleware implemented with CORBA through IIOP. CORBA server objects which provide a client with Open API is the essence of an interoperability. CORBA server objects wrap the data formats and access methods of different GIS engines, and translate the data formats of different data servers to a standard data format.

  • In this paper, we present an efficient way of implementing OpenGL ES 1.1 standard for the environments with hardware-supported OpenGL API, such as desktop PCs. Although OpenGL ES was started from the existing OpenGL features, it becomes a new three-dimensional graphics library customized for embedded systems through introducing fixed-point arithmetic operations, buffer management with fixed-point data type supports, completely new texture mapping functionalities and others. Currently, it is the official three dimensional graphics library for Google Android, Apple iPhone, PlayStation3, etc. In this paper, we achieved improvements on the arithmetic operations for the fixed-point number representation, which is the most characteristic data type for OpenGL ES. For the conversion of fixed-point data types to the floating-point number representations for the underlying OpenGL, we show the way of efficient conversion processes even with satisfying OpenGL ES standard requirements. We also introduced a simple memory management scheme to mange the converted data for the buffer containing fixed-point numbers. In the case of texture processing, the requirements in both standards are quite different and thus we used completely new software-implementations. Our final implementation result of OpenGL ES library provides all of over than 200 functions in OpenGL ES 1.1 standard and completely passed its conformance test, to show its compliance with the standard. From the efficiency viewpoint, we measured its execution times for several OpenGL ES-specific application programs and achieved at most 33.147 times improvements, to become the fastest one among the OpenGL ES implementations in the same category.

  • Precast Concrete apartments were main stream of domestic industrialized housing around 90's , and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel stud and Unit Box have their own merits an demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the Open System basis. In this study, the design standard for Unit house will be established coping with the established preparing standard for design specifications defined by Architectural Law and Promotion Law of Housing Construction. That is for design standard of industrialized private housing on the Open System basis.

  • A variety of BIM libraries are required to apply BIM(Building Information Modeling) software and generate BIM data. However, enterprises are establishing their own libraries using BIM tools, the drawbacks are that these libraries are not open to other users, or they just can be used in some software packages. If IFC(Industry Foundation Classes), the standard format of open BIM, can be applied, the BIM library can be applied in all the BIM software packages. Although the enterprises can collaborate using IFC standard, it is difficult to represent all the property information of the construction materials by IFC. IFD(International Framework for Dictionaries) is used to solve these problems and add the property information of the construction materials easily. Therefore, Open RIM-based library needs to be developed using IFD. In this research, the development and application of BIM library and IFD in domestic and foreign countries were investigated and analyzed, and Open BIM-based IFD scenario was proposed for using, and finally by applying an IFD method, the IFD data was added within an IFC model. Consequently, Open BIM-based library can be extended with rich, formal, and semantic descriptions and enhance data interoperability among BIM software packages adopting Open BIM standard format, by applying the IFD.

  • The purpose of this study was to investigate the normal range of condylar movement of normal adults. The author has observed roentgenographic images of four serial positions of condylar head taken by modified transcranail lateral oblique projection. The serial positions are centric occlusion, rest position, 1 inch open position and maximal open position. The results were obtained as follow; 1. Inter-incisal distance was 46.85㎜ in maximal open position. 2. The length between the deepest point of glenoid fossa and summit of condylar head in rest position was wider than that in centric occlusion by 0.8㎜. 3. In 1 inch open position, condylar head moved forward from the standard line in 12.64㎜ of horizontal direction and moved downwards from the standard line in 1.84㎜ of vertical direction. 4. In maximal open position, condylar head moved forward from the standard line in 19.06㎜ of horizontal direction and moved downwards from thestanard line in 0.4㎜ of vertical direction. 5. In centric occlusion, the width between glenoid fossa and margin of condylar head was greater in the posterior portion than in the anterior portion by 0.4㎜. 6. Except for the estimated figures of 1 inch open position, all of the estimated figures was greater in male than in female.

  • The 'NIST Framework and Road Map for Smart Grid Interoperability Standards' proposes an architecture framework to secure the direction of development and standard interoperability of smart grid and provides a list of identified standard, standard cyber security strategies, and certification framework. In particular, SEP 2.0 and OpenADR 2.0 are the examples. SEP 2.0 and OpenADR 2.0 can functionally link HEMS and Smart Grid, but interoperability standards between the two protocols are not planned in above document. The OpenADR Alliance also announced that work is underway to define mapping tables for interoperability between OpenADR 2.0 and SEP 2.0, but no information is yet available. Therefore, In this paper, in developing energy efficiency improvement HEMS, we propose a mapping model that supports syntactic and semantic founded interoperability between SEP 2.0 and OpenADR 2.0b for ICT grid convergence based on the standard specification document of each protocol and confirmed through an example of the semantic mapping function based on the demand response service scenario.
