In the study, we suggest that the activation plan of the public nature burial in the capital area through funeral information system as follows. First, according to the report on the social survey announced by the National Statistical Office in December 2017, the Korean people's preference of nature burial was 43.6% while the actual utilization rate of national nature burial in 2017 was only 8.8%, which showed a huge gap between preference and utilization rate of nature burial. Therefore, through the activities to improve the awareness of nature burial by performing the national promotion and education, and also the investment for the expansion or improvement of nature burial facilities in the level of central government and local government, the preference of nature burial should be led to the actual demand. Second, during the period from 2011 to 2018, the utilization rate of public nature burial in the capital area was annually increased by average 26.9%, which showed the huge increase of demand for nature burial. Thus, each local government should carry forward the policies for expanding the supply of public nature burial focusing on the woodland burial showing the high preference of users of public nature burial. Third, even though the public cremation facilities are installed or operated by local governments in the capital area, Seongnam City without the public cremation facilities should install the public nature burial for the enhancement of users convenience by providing the One Stop Total Funeral Service.

Based on a result of we research and analysis of this study, it was analyzed that the average annual cremators number using E-Haneul Funeral Information System among the five public cremation facilities in Jeollabukdo was 9,713 in total before the opening of public creation facilities in Jeongeup City (2013-2015), while the number was 12,159 after the opening of public cremation facilities in Jeongeup City (2016-2019); the number was increased by 2,446, compared to the opening period (2013-2015), with a large increase rate of 25.2%. In addition, the average annual cremation rate before the opening of public cremation facilities in Jeongeup City (from 2013 to 2015) was 71.6%, but the average annual cremation rate during the period after the opening (from 2016 to 2019) was 81.5%, which was a large increase rate of 9.9% compared to period before the opening of the facilities. Based on research results above, we have presented policy suggestions in order to increase the efficiency of operation and management of public cremation facilities by local governments as follows. First, in order to prepare for the increase in demand for cremation due to the increase in cremators number, a policy promotion for the expansion of "public cremation facilities" should be carried out as soon as possible, focusing on local governments whose supply has reached the limit. Second, in order to support the expansion and construction of public cremation facilities, the government subsidy rate and government subsidy at the level of current 70%, provided by the central government, should be further expanded. Third, overcoming theNIMBY conflict overlocation for public cremation facilities, theutilization rate should be enhanced, through the joint construction and facility operation of the public cremation facilities between local governments, and the ef iciency of the project implementation should be improved through the jointsharing of the facility operation cost.

무선에 의한 서비스는 유선에서 제공할 수 없는 단말기의 이동성이라는 커다란 장점을 지니기 있기 때문에, 댁내에서의 광화이버 배선으로 여러 가지 문제점을 발생시키고 경우에 따라서는 해결이 불가능한 경우도 무선에 의한 광대역 서비스의 제공이 가능하다. 최근까지는 2.5GHz 대역에서 아날로그 AM방식인 MMDS(Multichannel Multipoint Distribution Service)로 무선 CATV같은 서비스가 진행되어 왔다. 그러나 MMDS 방식의 경우 주파수 배정 문제로 인하여 발전이 한정적으로 이루어져 왔고, 양방향 디지털 및 다채널기술의 적용을 위한 주파수 대역의 확보가 어렵기 때문에 미래의 기술로 적용하기에는 다소 무리가 있는 것으로 분석되고 있다. 따라서 이에 대한 해결책으로 새로운 주파수 자원의 개발과 디지털 다채널 기술을 적용한 초고속 광대역 무선 전송기술의 개발이라는 측면에서 새로이 개발된 것이 최근 연구의 중심을 이루고 있는 LMCS(Local Multi-point Communication System)방식이다. LMCS 시스템은 25GHz∼29GHz 정도의 주파수를 사용하며 디지털화하여 양방향 CATV로 전환함으로써 양방향 멀티미디어 서비스가 가능하고, 향후 정보고속도로와도 연계할 수 있다는 점에서 최근 관심이 집중되고 있으며 많은 연구가 이루어지고 있는 상황이다. 이러한 추세에 따라 국내에서도 LMCS방식의 무선 CATV 서버용 주파수가 배정될 예정이다. LMCS기술은 유선망보다 저렴한 설치비용, 신속한 망구축 등의 장점을 바탕으로 양방향 초미터파 대역으로 고유한 전파전파 특성을 가지고 있으며, 주파수 배정에 있어서도 광대역으로 예상되기 때문에 LMDS에 대한 연구가 필요하다.

Recently, extending the local broadcasting and increasing lots of informations. The low-loss communication cable is required in proportion as frequency .The reason of transportation loss causes to using the high frequencies like hundreds of MHz or decades of GHz. For the low transportation loss. It is required the developing-technology of foaming and the high foamed insulator with the dielectric ratio of the nearest to 1. Therefor, there is the purpose of developing the insulating materials for the low dielectric ratio. Also it is important to measure the attenuation, which is one of the important parameters.sa the evaluation of transportation characteristic with frequency in the communication cable. In this paper,the result showed that the dielectric ratio(1.4) of the nearest to 1 and low attenuation with high frequency were very related to the transportation and reflection characteristics such as propagation velocity (82.27%). Delay time and voltage standing wave ratio(VSWR).

Oncolytic viruses are characterized by their ability to selectively kill cancer cells, and thus they have potential for application as novel anticancer agents. Despite an increase in the number of studies on methodologies involving oncolytic viruses, bioinformatic studies generating useful data are lacking. We constructed a database for oncolytic virus research (the oncolytic virus database, OVDB) by integrating scattered genetic information on oncolytic viruses and proposed a systematic means of using the biological data in the database. Our database provides data on 14 oncolytic viral strains and other types of viruses for comparative analysis. We constructed the OVDB using the basic local alignment search tool, and therefore can provides genetic information on highly homologous oncolytic viruses. This study contributes to facilitate systematic bioinformatics research, providing valuable data for development of oncolytic virus-based anticancer therapies.

This paper addresses the process of information dissemination in a network whereby a message, originated at a node, is transmitted to all other nodes of the network. We restrict our attention to a speccial type of dissemination process,called 'local broadcasting', where a vertex can either transmit or receive a message and an informed vertex can transmit it to only one of its neighbors at a time. Based on the recently published results for a tree by Koh and Tcha, this paper proposes an efficient heuristic which determines the call sequence at each vertex node under both minimax and minisum criteria. Computational experiments with this heuristic are conducted on a variety of networks of medium size.

A multiband meandered monopole antenna is proposed for digital video broadcasting handheld (DVB-H), global positioning system, personal communications service, wireless broadband (Wibro), and wireless local area network (WLAN) applications. The proposed antenna consists of a meandered line, a shorted length strip line, and a conductor strip between a meandered line and a microstrip feed line. By tuning a short strip and a conductor, a multiband impedance matching is achieved. The proposed antenna has an omnidirectional radiation and yields an antenna gain of greater than -3 dBi in the DVB-H band and 4.5 dBi in the Wibro and WLAN bands. Details of the proposed antenna design and experimental results are presented.

This study deals with the problem of information dissemination in a communication network, which is defined to be the process whereby a set of messages, generated by an originator, is transmitted to all the members within the network. Since this type of message generally includes control data to manage the network or global information that all members should know, it is to be required to transmit it to all the members as soon as possible. In this study, it is assumed that a member can either transmit or receive a message and an informed member can transmit it to only one of its neighbors at time. This type of transmission is called 'local broadcasting' Several schemes of call sequencing are designed for a general-type network with nonuniform edge transmission times, and then computer simulations are performed. Some heuristics for information dissemination are proposed and tested. For this, optimal call sequence in a tree-type network, sequencing theory and graph theory are applied. The result shows that call sequencing based on the shortest path tree is the most desirable.
