In Korea, the government has developed SEUMTER, an administration system for building related public service, to facilitate and promote the electronic submission and permission activities. SEUMTER is progressing legality system based on 2D drawing for building administration permission service. However, there are a lot of problems related to legality system owing to complexity of Korea regulation relation and structure, inefficiency of legality system based on 2D drawing, duplication examination of document (soliciting forms for civil affairs) and drawing. Therefore, the purpose of this study is to develop legality system for building administration permission service based on BIM in Korea. To achieve this purpose, the authors have investigated permission procedure and regulation structure that is used in current building administration permission and suggested permission procedure and regulation structure for legality system based on BIM. In addition, the authors have investigated element technologies (for examples, method of structured regulation, BIM model checker, Viewer, etc) for legality system based on BIM. Finally, the authors have suggested strategy and hereafter direction for application of legality system based on BIM.

The Council Regulation (EEC) No 2092/91 of 24 Juni 1991 on organic production of agricultural products and indications referring thereto on agricultural products and foodstuffs. This Regulation describes the legal framework for agricultural products and foodstuffs obtained organically. The Regulation establishes a harmonized framework for the production, labelling and inspection of agricultural products and foodstuffs in order to increase consumer confidence in such products and ensure fair competition between producers. This article presents a study about inspection and certification system of organic production of agricultural products and foodstuffs in Germany. In order to guarantee respect for the rules of production, the Regulation provides for an inspection system to ensure that operators who produce, prepare or store organic products or import them from third countries notify the competent private and public authorities in the Member States of their activities. These inspection authorities must, at the very least, ensure application of the minimum inspection and precautionary measures laid down in Annex III to the Regulation. For the production of meat, the Regulation states that the Member States must guarantee the traceability of products throughout the production, processing and preparation chain.

While making a vigorous discussion about self-regulation for exponential growth of harmful health information on the Internet, many countries lave made various efforts to select and circulate high quality health information on the Internet. The purpose of this study Is to review the serf-regulation methods of health information on the Internet and to suggest quality control methods of health information on the Internet suitable for Korea. Self-regulation methods of the health information on the Internet include ‘content rating system(or content selection system)’, ‘codes of conduct or guideline’, ‘internet hot-line’, ‘education for information providers and consumers’. Any self-regulation method should be used with other methods. We can regulate health information on the Internet effectively by using both self-regulation methods and compulsive methods such as law. Also information providers, information consumers, specialists, consumer representatives, scholars, governments officers should take part in doing these efforts and make concern.

Recently, the large scaled energy storage system(ESS) which has various functions such as peak saving, demand management, output stabilization of renewable energy and frequency regulation(FR) is being energetically installed and operated. Especially, as the use case of frequency regulation ESS, the KEPCO has demonstrated the total of 376[MW] ESS since 2014. However, there are no operational experiences and international technical standards on frequency regulation application in ESS. Therefore, this paper propose the evaluation algorithm for power system performance of ESS by considering the frequency characteristics between governor of existing generator and frequency regulation ESS, in order to verify the power system performance of ESS. And also, this paper propose an evaluation modeling for small scaled power system including the existing generator, frequency control ESS and customer loads based on the PSCAD/EMTDC S/W. From the simulation results in 360[MW] model power system, it is confirmed that frequency regulation ESS has better performances than conventional generators.

In this paper, we consider the aortic sinus baroreceptor, which is the most representative baroreceptor sensing the variance of pressure in the cardiovascular system, and propose heart activity control model to observe the effect of delay time in heart period and stroke volume under the regulation of baroreflex in the aortic sinus. The proposed heart activity baroreflex regulation model contains electric circuit sub-model. We constituted the time delay sub-model to observe sensitivity of heart activity baroreflex regulation model by using the variable value to represent the control signal transmission time from the output of baroreflex regulation model to efferent nerve through central nervous system. The simulation object of this model is to observe variability of the cardiovascular system by variable value in time delay sub-model. As simulation results, we observe three patterns of the cardiovascular system variability by the time delay, First, if the time delay over 2.5 second, aortic pressure and stroke volume and heart rate is observed nonperiodically and observed. Finally, if time delay under 0.1 second, then heart rate and aortic pressure-heart rate trajectory is maintained in stable state.

Current research and development efforts and other projects for energy storage systems (ESS) have recently been gaining attention. This is due to the many applications where ESS, particularly batteries, can be used. Among these are peak shaving, frequency regulation, and stabilization of renewable energy output. KEPCO has completed the construction and demonstration of a 4-MW battery energy storage system (BESS) located in Jeju City to verify its practicability in the power grid. KEPCO Research Institute has also been developing technology for the commercialization of BESS, and has been conducting a trial run of a 52-MW ESS (28MW + 24MW of Seo-Anseong and Shin-Yongin substations) constructed in 2014 for frequency regulation. This paper discusses the development of operation methods, as well as an operation user interface, for the safe operation and monitoring of BESS used for frequency regulation in a power system. Included are operation and simulation methods for various normal and transient frequency situations that can be experienced by a power system. Also discussed are the results obtained after applying these methods to the 4-MW BESS and the 52-MW ESS, both used for frequency regulation. The technology in this paper will be applied to 500MW ESS for frequency regulation of KEPCO by 2017. It is expected that this technology helps a safe and reliable operation and control of ESS for frequency regulation through its continuous upgrade.
