With the development of ICT technology, the broadcasting and communication networks of Korea have been bigger, faster and more reliable and Korea has become one of the leading countries in the ICT industry. Through the international ICT indices, we can see different economies' ICT industry competitiveness at a glance and high ranking in such indices can make national brand image improve. However almost all the existing international ICT indices mainly focused on the telecommunication industry, not on the broadcasting industry. This study thus aims to develop a new index focusing on broadcasting and communication networks. This new index is composed of 3 sectors such as access, usage and environment with different weight respectively and using objective indicators. This study also aims to contribute to improve Korea's national brand image by developing new systematic and effective broadcasting and communication index.

In the era of ultra high speed information communication technology represented by Smart phone and Tablet PC, the disable and the aged people came to be in a position of so-called 'relatively weak people' in the field of information communication due to inconvenience of use and difference in information acquisition and processing ability. Thus, a survey was conducted on Smart phone accessibility items based on previous studies of the disabled with crippled disorder, brain lesions, myelopathy and muscular disabilities having more inconvenience relatively in their use of smart phone due to upper limb dysfunctions. Especially, people with upper limb dysfunctions with relatively weak grip had big inconvenience in the conditions of uses requiring actions such as grabbing and rotating the devices, and due to the characteristics of touch screen input method of Smart phone, they had big inconvenience due to a lack of a guidance for keyboard in input. As a result of questionnaires by the type of disability, it turned out that severe myelopathy causes the most inconvenience in using smart phone.

As the need for sharing for research purposes in the medical field increases, the use of a Common Data Model (CDM) is increasing. However, when sharing CDM data, there are some problems in that access control and personal information in the data are not protected. In this paper, in order to solve this problem, access to CDM data is controlled by using an encryption method in a blockchain network, and information of CDM data is recorded to enable tracking. In addition, IPFS was used to share a large amount of CDM data, and Celery was used to automate the sharing process. In other words, we propose a multi-channel automation system in which the information required for CDM data sharing is shared by a trust-based technology, a distributed file system, and a message queue for automation. This aims to solve the problem of access control and personal information protection in the data that occur in the process of sharing CDM data.

Public institutions and governments develop discussions on the premise that they can facilitate smooth public communication with the socially vulnerable by promoting citizens' welfare by providing voice-based service chatbots to citizens. The purpose of the study is to propose a plan for intelligent governments to provide quick and efficient administrative services by efficiently managing knowledge and information within and outside government organizations based on ICT and facilitating access and use of information for citizens, especially vulnerable groups. This paper confirms that citizens' attitudes, perceptions, and expectations for public institutions ahead of voice-based service provision are positive through small surveys and interviews with experts with knowledge of artificial intelligence, discuss the technical aspects of voice-based services, the significance and necessity of public institutions. In addition, the government and public institutions are considering the implications of using and providing voice-based services. As a result, chatbot's voice-based service is of great significance in providing an opportunity and platform for wider citizens to participate in intelligent government, to strengthen information accessibility, guarantee and strengthen human rights and basic rights of the socially vulnerable.

Although the use of kiosks is increasing recently, the digital divide for the elderly who uses them is not decreasing. We live in an environment where the use of kiosks is becoming a necessity rather than an option. In such an environment, the digital alienation of the elderly is becoming a problem directly related to the quality of life. Even if a kiosk is developed considering the elderly, the verification of its effectiveness is ambiguous, or in most cases, it depends on the designer's experiential ability rather than the consideration of usability. In this study, the usability of the kiosk was analyzed for the development of kiosk contents for the elderly. The metrics were defined as availability, usefulness, efficiency, attractiveness, and visibility. And the measurement method of the measurement index was developed, and the usability of the kiosk for the elderly was confirmed by performing usability evaluation. This is a method to verify whether the kiosk in the development process can support the elderly or whether the improved kiosk actually increases the usability of the elderly. As a result, it is expected to contribute to improving the accessibility of the kiosk.

Electronic contract systems are widely used to integrate and manage the contract management process based on the development of ICT technology. Recently, improvement methods using block chain technology are being studied. However, contract management systems have processing performance, security vulnerabilities, data entry, and service accessibility issues. In this paper, we propose a block - chain based contract management platform with block chain, smart contract, and Rest API. The suggested platform includes the RPBFT algorithm which solves the processing performance and security vulnerability of the existing consensus authentication algorithm, and the algorithm to prevent data entry and enhance transparency of participants. The block-chain-based contract management platform proposed in this paper provides a use environment with improved processing performance, security, reliability, and transparency, and can be used through API without burdening construction. Therefore, The effect can be expected.
