This study attempted to find a way to utilize idle spaces in rural areas as a way to respond to rural extinction. Based on the keywords "startup," "youth start-up," and "youth start-up+rural," start-up+rural," the study sought to identify the perception of idle facilities in rural areas through the keywords "Idle facilities" and "closed schools." The study presented basic data for policy direction and plan search by reviewing frequency analysis, major keyword analysis, network analysis, emotional analysis, and domestic and foreign cases. As a result of the analysis, first, it was found that idle facilities and school closures are acting importantly as factors for regional regeneration. Second, in the case of youth startups in rural areas, it was found that not only education on agriculture but also problems for residence should be solved together. Third, in the case of young people, it was confirmed that it was necessary to establish digital utilization for agriculture by actively starting a business using digital. Finally, in order to attract young people and revitalize the region through best practices at home and abroad, policy measures that can serve as various platforms such as culture and education as well as startups should be presented in connection with local residents. These results are significant in that they presented implications for youth start-ups in rural areas by reviewing start-up recognition for the influx of young people as one of the alternatives for the use of idle facilities and regional regeneration, and if additional solutions are presented through field surveys, they can be used to set policy goals that fit the reality.

Safety management was divided by the competent authorities supplier, and customer with responsibility and authority. Gas accident were caused by treatment problem on the supplier and user, on technical and use management mater, on facilities and goods, and included problem with gas safety connection system. Especially, the big accident of the inside and outside of the country occurred during recent year was newly recognized with the whole society about safety. This study is present standard application plan of each department to use planning gas technical standard and gas utilization standard of introduction model than statute for change of self-regulation management system and complicated regulation of examination center and order.

The construction of settlement house in a permanent rental housing development area started between 1989 and 1992, planning of supplying two hundred fifty thousand residences, settlement house became compulsory as a welfare facilities. As a part of Welfare program for low income families, number of settlement housing increased dramatically, also domiciliary welfare center was beginning to set up as a branch of settlement housing to strengthen its service towards families and local communities, thus numerous social welfare organizations play a crucial part in resolving a welfare problem for low income families while satisfying local community's needs. However, despite of these efforts, the number if institutions cannot handle demand of local community's needs and number of welfare institution programs. as a solution, the alternation of space is being used, however, it did not solve basic problem, even worsen in terms of space efficiency.

The present conditions of Sanyangri village at Samcheok are stagnated and spiritless because there is only old men without young men. The purpose of this study is to make the basic plans of this rural and mountainous village to learn by personal experience. Therefore this study has been focused on its programs, land uses, roads and facilities how to activate it. The plan orientation of it is to make and become active by tourists to visit this village to experience the rural and mountainous living culture. So the general plan is divided into two zone which are the rural experience zone and the mountainous experience zone. Also the plan is to be considered to increase its amenities through the connection of surrounding villages and their resources. And it is necessary for the conversion as a tour place of sojourn and experience by supplying with various shows through connections with surrounding tour resources worthy of providing the various excitement through the visiting.

Softswitch is the core BcN equipment which voice and multimedia switching based on the IP Technologies. It is designed to replace the Class 5(local Exchange) and Class 4(Toll Exchange) switch based on the circuit wired and wireless switching network technologies. Softswitch gets its name because typically it is a software based solution implemented on general purpose computers/servers. While the traditional PSTN switches are rely on dedicated facilities for T and S inter-connection and are designed primarily for voice communications. Packet based Softswitch is divided the control of call and bearer, very different from Public telephone network. Sometimes Call Agent or Media Gateway Controller, a key component in the VoIP solution, is also called Softswitch. This paper will suggest the software architecture of softswitch for performance in call processing part, also suggest the session management model to cover call setup latency.

Traditionally SCADA is connected only in a limited private network. With new technology and facilities, there are also demands of connecting SCADA though the internet. The internet SCADA facility has brought a lot of advantages in terms of control, data viewing and generation. Aside from connecting SCADA to the internet, there are also operators who want to connect their system wirelessly. This can save budget for communication lines. Along with the advantages it brings, are security issues regarding wireless internet SCADA. In this paper, we discuss internet SCADA, its connection through wireless communication and the security issues surrounding it. To answer the security issues, a symmetric-key encryption for internet SCADA is proposed.

Purpose of the grounding system design are establish a safe environment for personnel as well as the general public in the vicinity of the power system equipment, and establish a low resistance connection to earth such that protective devices detect and isolate faults quickly and potential rise of the grounding system does not exceed a value which could damage electrical equipment. This paper deals with the grounding system design for the electric facilities. In this paper, emphasize the necessity of the computer programs for the grounding system designs. Especially, earth soil models for the grounding system design are must used two-layered soil model.

This paper describes a development of the temporary transformer system and method. The failure causes are genrally divided into problems in manufacturing, mounting and operating. To replace the bum-out pole transformers developed various facilities, power cable clamp, the control panel of self-sensing device and voltage connection box etc. That is more effective to establish the emergency transmission systems for the non interruption replacement of distribution transformers.

For several ten years, the Internet and IT services have been greatly developed in PC area and with this, new BM and services with terminals like Post-PC and Non-PC types will come into the spotlight in few years. In various fields of service, terminals exclusive to individual service come into the market already, the hardware and the contents used in the terminals are circulating. The communication service providers are very enthusiastic about developing and providing various services in order to overcome the growth limit of existing network connection service. And they think that providing the Non-PC type Information Appliance services will make added values and be sources of making profits in next generation. Hereupon we are going to observe the Non-PC type Information Appliance services, the structure of the service platform that make that services possible, and their prospect.

This paper proposes a multicast scheme over IEEE 802.16 networks which support multiple upper layer protocols such as ATM, IPv4 packets, IPv6 packets, IEEE 802.3 over IPv4 and so on. The multicast capabilities over IEEE 802.16 are important both control plane and data plane. The proposed multicast scheme can be divided into two types: direct mapping and indirect mapping. The direct mapping scheme is that layer 3 address is directly mapped into CID information which is used for connection identifier at IEEE 802.16 link layer. The indirect mapping scheme has two steps for mapping between layer 3 address and layer 2 CID. Firstly, a layer 3 address translates to Ethernet MAC address with group MAC address. Secondly, a group MAC address is mapped into CID. The mapping scheme depends on the upper layer protocols.
