For last about 10 years, the Republic of Korea experienced 3 times of outbreaks of highly pathogenic avian influenza (HPAI) from 10 December 2003 to 30 April 2004 (a total number of 19 outbreaks), 22 November 2006 to 6 March 2007 (a total number of 7 outbreaks), and 1 April 2008 to 12 May 2008 (a total number of 33 outbreaks). Among the totally 59 outbreaks, the infected premises included 35 chicken farms, 17 duck farms, 1 quail farm, and 6 farms rearing mixed species. Control measures were applied according to the HPAI standard operation procedure including depopulation of all infected and suspected flocks, movement restrictions, and disinfection of the infected farms within a 500-meter radius. Including movement restrictions, stringent control measures were additionally applied to two designated zones: the protection zone was an area within a 3-kilometer radius of the outbreak farm, and the surveillance zone was an area between a 3- to 10-kilometer radius of the outbreak farm. Farms with dangerous contacts and/or all of poultry within the protection zone was subjected to preemptive culling. Epidemiological investigations were also carried out including trace-back and trace-forward investigations to identify possible sources of spread and dangerous contact farms. Investigation teams conducted on-site examination of farm premises and facilities, interview with farm owner and staff, and review of records. Genetic and pathogenic characteristics of the virus isolates, and the results of the various surveillance activities were also analyzed. HPAI surveillance conducted in Korea includes passive surveillance of investigating notified cases, and active surveillance of testing high risk groups and areas. HPAI is a notifiable disease in Korea and all suspect cases must be reported to the veterinary authorities. Cases reported for other poultry diseases that require differential diagnosis are also tested for HPAI. Active surveillance includes annual testing of breeder duck farms, broiler duck farms and wild bird surveillance, which is concentrated during the autumn and winter. Surveillance activities conducted prior to the outbreaks have shown no evidence of HPAI infection in Korea.

An electric point-machine which changes over a turnout so that it enables a train to be operated in the routine that a train is to proceed has been installed and used in most of the railways such as not only urban railways but also main-line railways. Most of the maintenance works in this electric point-machine is that the maintenance workers manually measure motor power, control power and display power in the site with the use of portable counters. Especially in case of NS or NS-AM electric point machine, the maintenance cycle is so frequent that during the operation casualty accidents caused by carelessness occurs as well as more staff is required for this measurement. In this paper we propose a system for monitoring the state of electric point machine installed in the site to improve maintenance efficiency and it is expected that this monitoring system confirms any measured values on electric point machines in real-time and improves maintenance efficiency.

With the development of IT, hacking crimes are becoming intelligent and refined. In Emergency response, Big data analysis in information security is to derive problems such as abnormal behavior through collecting, storing, analyzing and visualizing whole log including normal log generated from various information protection system. By using the full log data, including data we have been overlooked, we seek to detect and respond to the abnormal signs of the cyber attack from the early stage of the cyber attack. We used open-source ELK Stack technology to analyze big data like unstructured data that occur in information protection system, terminal and server. By using this technology, we can make it possible to build an information security control system that is optimized for the business environment with its own staff and technology. It is not necessary to rely on high-cost data analysis solution, and it is possible to accumulate technologies to defend from cyber attacks by implementing protection control system directly with its own manpower.

This study examined the experience of administrators of home-based child care centers about CCFSM (Center for Children's Foodservice Management) service using a qualitative approach. Eight administrators of home-based child care centers in Seoul with more than one year's experience of CCFSM were interviewed regarding their opinions on support activities, standards, and foodservice management. The interviews were semi-structured with open-ended questions and they were transcribed and classified according to the subjects. There were negative opinions regarding the indications after a hygiene inspection leaving photographs or records behind, but most positive opinions were about round visits for foodservice sanitation and nutrition management. The participants thought that it is not enough that the number of nutrition education sessions for children be twice a year, and there was a suggestion to increase the rentals of nutrition educational materials. There was a complaint about the menus in that were difficult to prepare for lunch time or to obtain food ingredients for. The administrators poorly recognized how to use the standardized recipes and chlorine-based disinfectants, so they could not be applied properly. They also pointed out the problems of joint purchasing as low quality and high prices in the food service operation. They felt discriminated against compared to with larger scale child care centers because of their size and expressed concerns regarding the fact that many home-based child care centers were not included due to the lack of publicity and budget. Through the results, the CCFSM should provide a differentiated service and management by creating a dedicated team or staff for home-based child care centers so they will not feel left out. In addition, It is also important to constantly gather opinions to improve the menus and to use standardized recipes practically. In addition, it will be necessary to develop nutrition educational materials corresponding to the infants' age for home-based child care centers and increase the rent to expand nutrition education.

The purpose of this study is to study the technical implementation methods to prevent problems such as the record of important educational activities of the student life record department or the continuous illegal leakage and manipulation. To this end, in this paper, by applying a private blockchain that can be participated only by a given organization or individual, it prevents outsiders from participating in the block network, and creates legitimate authority by creating two types of block data: student information block and access record block in the life record book. We proposed a block mechanism that can be registered, modified, and accessed only by authorized staff members. As a result, we have prepared an alternative to prevent forgery and alteration of the living records by third parties and to secure the integrity of the living records. If applied to the educational administrative information system, social consensus will be established that the operation and management of the life record book is reliable.
