The use of the Internet of things plays a major role in the Fourth Industrial Revolution, and a series of tasks of accumulating, converging, analyzing and reusing various data and services becomes very important. Because the pace and scope if the paradigm shift in Fourth Industrial Revolution is so rapid and unpredictable, the development and utilization of a system to fulfill this role for IOT are urgently required. In this paper, we introduce the Web-based IOT management system, which connects the IOT with OKMindmap, which is a domestic open source software and service, and the Node-RED service. This system combines the advantages of OKMindmap with the advantages of Node-RED, which is capable of visual component based programming, so that it can easily and flexibly connect the IOT based on Web browsers, and various data and services can be integrated and linked. We developed a camera module, a temperature and humidity sensor module, and the motor control module in Raspberry PI basically, and tested the operation successfully. We plan to extend the IOT component gradually by using Arduino and System On Chip.

The purpose of this study was to explore ways a digital therapeutics-based community care plans for the rehabilitation in dysarthria in a situation where non-face-to-face services are expanding in the COVID-19 era. To this end, a qualitative study was conducted on experts working in hospitals, speech-language pathology centers, and social welfare centers, and as a result of the study, 3 topics, 9 sub-themes, and 18 content units were derived. Based on the analysis results, the digital therapeutics-based community care model consisted of 9 types: remote diagnosis, telepractice, rehabilitation training program, peer supporters, clinical support, communication, psychosocial intervention, and care plan services. This study will be able to provide basic data for health care & welfare services using digital therapeutics and guidelines for establishing shared care plans based on multidisciplinary cooperation.

This study explores the characteristics of the delivery system of the New Deal, with a particular attention to the partnerships and welfare governance. The study analyzes the partnerships of the New Deal policy in Britain, which consist of two dimensions of partnerships. The results are: First, the method of the transformation of delivery in central government dimension is the unity of the governmental organizations, Another outcome of reform in the central government dimension is the establishment of the Jobcentre Plus. Second, the characteristic of delivery system in public-private dimension is the contract through competition, which means the introduction of market paradigm. Especially, the reform of the delivery system in the local dimension is to deliver integrated services through the introduction of labour market paradigm in demand-side. The central government also supports the reform in the local level. This study also explores the forms of welfare governance in these dimensions, This study suggests the importance of united services in the Korean welfare to work.

Creating more efficient and effective intermodal transportation service in Northeast range is a critical issue because of more increased trade volume & demand for intermodal service in the world market and geographical barriers associated with goods transportation, especially in Korea, China and Japan. This study examines the possibility of Rail-ferry introduction and possible route in Northest area which can provide each country mutual economical and logistical satisfaction. But, this study requires more empirical and concrete examination based on the cost & benefit analysis.

어떤 아웃소싱에서건 성과 측정을 못하면 관리할 수 없다. 기존의 ITO 서비스 측정 기준이 IT중심의 SLA이었다면, 본 논문에서 말하려는 ITO 서비스 측정 방법은 ITO 서비스에 대한 비즈니스측면의 가치 평가를 시도한 것이다. 기업의 성과평가를 위해 적용되는 BSC 개념을 ITO서비스에 도입하여 IT BSC체계를 확립하고, 이를 조직내 의사결정 레벨로 관리함으로써 ITO서비스 측정 지표값이 조직의 비즈니스 성과에 영향을 준다는 근거를 마련하고자 하는 것이다. 이로인해 사업목표와 연계된 ITO서비스 측정 기준을 마련함으로써, IT예산 산정의 합리적 근거를 확보할 수 있다.

통합공공용 주파수로 분배된LTE(Long Term Evolution) 718~728Mhz(상향) 및 773~783MHz(하향)에서 재난안전 통신망, 철도무선 통신망, 차세대 해상무선 통신망 등과 같은 LTE기반의 공공통신망(Public Network, 이하 공공망)이 상호 공존하여 사용하는 방안에 대하여 연구하였다. 두 개 이상의 복수의 LTE 네트워크가 동일 주파수를 사용하여 서비스하는 경우 통신 커버리지가 겹치는 영역에서의 간섭은 불가피하다. 셀 간 간섭에 의하여Mission Critical한 요구사항이 중요시되는 공공망에서의 품질 열화가 야기되며, 경우에 따라 심각한 상황을 초래할 수 있다. 본고에서는 국내 공공망의 현황을 살펴보고 네트워크 공유방식에 대한 기술 및 표준화 동향, 그리고 해외의 사례를 알아보았다. 국내 통합공공용 주파수에서 동일 주파수를 사용하게 될 공공망 간의 간섭을 최소화 하여 네트워크를 구축 및 연계를 위해서 개별 공공망간의 네트워크를 공유하는 방안을 고려하였다. 국내 공공망의 효율적인 네트워크 연계를 위해서는 개별 공공망의 서비스 특성과 내부 환경을 반영 할 수 있는 연계 방식이 추가적으로 필요하다.

제품의 개발 및 생산 과정에는 설계, 해석, 가공, 검사 등의 많은 부문이 서로 밀접하게 연계되어 있고 각 부문 간에는 각기 서로 다른 형태의 정보를 필요로 하기 때문에 이들의 유기적인 통합을 위해서는 각각의 응용 분야에서 요구되는 다양한 정보가 효과적으로 제공될 필요가 있다. 본 연구에서는 특징형상을 이용하여 설계 기능과 다른 응용 부분을 유기적으로 연계할 수 있는 알고리즘을 제시한다. ISO에서 진행 중인 STEP의 Form Feature을 기준으로 일반적인 분류를 하고 이를 기초로 특징형상을 인식하고자 하였다. 이를 위해 B-Rep 데이터로부터 Face-Edge Graph를 구성하고 다중 절점(Cut Node)을 인식하였으며, 본 연구를 바탕으로 하여 향후 몇 가지 단점을 보완하고 대상 영역을 확대시켜 감으로써 Computer-aided Design 시스템으로부터 얻어지는 3차원 형상 데이터로부터 Computer-aided Process Plan을 위해 필요한 특징형상을 컴퓨터에 의해 자동으로 추출하기 위한 발판을 구축할 수 있을 것이다.

Public service provision through internet is one of major parts for e-government implementation. It is essential to link the internal administrative network with internet to provide the services through internet and to support kiosks through internet, which should result in critical issues for security. A relay server, as a front server for the public service processing system and a web server, a control server for kiosks, are placed between the public service processing system and kiosks to solve those security issues. It is the way to solve security issues through protecting direct communication between the public service processing system and a web server and authenticating a relay server and a web server through authentication process. In the implementation of the system this paper provide a design for an architecture model of the public service processing system through internet, which are aiming to develop high level of the quality system effectively, to reduce the risk of initial stage of development, and to reduce the incurring cost due to reworks.
