Recent development and generalization of Internet technology contributes to the large scale of commerce and capital followed by appearance and growth of large portal sites. As a result, the personal data on the Internet not deleted for a long period of time is a new risk factor, for example, the invasion of people's privacy. In particular, exposing personal data like witch-hunts is a critical issue so that the person concerned cannot carry on with normal life. This study suggests the necessity of the right to request personal data deletion related to a person concerned on Internet sites, a method of introducing the right in Korea, and a method of improving the application.

The immutability of blockchain is core elements of security of blockchain and guarantee data integrity. However, the characteristic that the data recoreded once in the blockchain cannot be modified has place for abuse by a specific user. In fact improper contents that is inappropriate to be recorded on the blockchain, such as harmful data and user personal data, is exposed on Bitcoin. As a way to manage improper content existing in the blockchain, there is a redactable blockchain using chameleon hash proposed for the first time by Ateniese. The redactable blockchain meet the right to be forgotten of GDPR by allowing data modification and deletion. Recently, Research on personal data management is being conducted in a redactable blockchain. Research by Jia et al. proposed a model that enables users to manage their personal data in the redactable blockchain. However, semi trusted regulators, which are blockchain participation nodes, have powerful authority in the blockchain, such as modification rights and deprivation of transaction rights for all blocks, which may cause side effects. In this paper, to weaken the authority of regulators in Y. Jia et al., we propose a method of authority subject altering and authority sharing, and propose a redactable blockchain-based authority change and access control system model based on applicable scenarios.

This study aims to critically discuss the problems that need to be solved from a humanities perspective in order to utilize big data. It identifies and discusses three research problems that may arise from collecting, processing, and using big data. First, it looks at the fake information circulating with regard to problems with the data itself, specifically looking at article-type advertisements and fake news related to politics. Second, discrimination by the algorithm was cited as a problem with big data processing and its results. This discrimination was seen while searching for engineers on the portal site. Finally, problems related to the invasion of personal related information were seen in three categories: the right to privacy, the right to self-determination of information, and the right to be forgotten. This study is meaningful in that it points out the problems facing in the aspect of big data utilization from the humanities perspective in the era of big data and discusses possible problems in the collection, processing, and use of big data, respectively.

In the EU GDPR, when collecting personal information, the right of the information subject(user) to consent or refuse is given the highest priority. Therefore, the information subject must be able to withdraw consent and be forgotten and claim the right at any time. Especially, restricted IoT devices(Constrained Node) implement the function of consent of the data subject regarding the collection and processing of privacy data, and it is very difficult to post the utilization content of the collected information. In this paper, we designed and implemented a management system that allows data subjects to monitor data collected and processed from IoT devices, recognize information leakage problems, connect, and control devices. Taking into account the common information of the standard OCF(Open Connectivity Foundation) of IoT devices and AllJoyn, a device connection framework, 10 meta-data for information protection were defined, and this was named DPD (Data Protection Descriptor). we developed DPM (Data Protection Manager), a software that allows information subjects to manage information based on DPD.

This study investigated the formation of communication education which is based on the contemporary language education. Concretely I watched chronologically the proportion of culture element and behavior element, its change, and the contents of writing education. To achieve this, I took the ancient Greek language education as the main materials. The sophists are right if we think only the empirical world, because of the changeability of external world and the relativity of sense. On the other hand, Platon emphasized the ability of abstract thought which is inherent in the human inside. But today's education only emphasizes the 'expression' which came from the Platonic thought. So students fills their devastated inside with arbitrary idea in this history-forgotten social circumstance. It is very beneficial to make subject have some cultural studies and to enhance the sensation on the world through the writing of representation because these can be good to the growth of subject. It is our-not as educator but as a predecessor of human being-duty to set the catalogue of cultural studies of this age and to make students feel the fundamental harmony and the beauty of the world.

In this paper, we propose a new blockchain technology that could comply with GDPR. The proposed model can prevent illegal access by controlling access to the personal information according to a access policy. For example, it can control access to the information on a role-basis and information validation period. The core mechanism of the proposed model is to encrypt the personal information with public key which is associated with users attributes policy, and then decrypt it with a private key and users attributes based on a Attribute-based Encryption scheme. It can reduce a trusted third-part risk by replacing it with a number of nodes selected from the blockchain. And also the private key is generated in the form of one-time token to improve key management efficiency. We proved the feasibility by simulating the proposed model using the chaincode of the Hyperledger Fabric and evaluate the security.

This paper explores the work of mourning of 9/11 in the United States, focusing on the project of building the National September 11 Memorial managed by the Lower Manhattan Development Corporation(LMDC) and the War on Terror declared by the George W. Bush administration in the wake of 9/11. This paper first looks at the project of building the Natioanl September 11 Memorial and considers what was at stake in achieving this project. It also examines the limitations of the project. This paper argues that, in spite of the efforts to mourn the victims in significant and meaningful ways, the work of mourning in the memorial project fails at least in two respects. First, the memorial project "began so soon" right after 9/11 that the victims' families were not given enough time to mourn their loved ones. Second, the project were permeated with American nationalism and patriotism, which made the 316 non-American victims of 9/11 invisible and forgotten. Then, it goes on to examine the War on Terror because the War on Terror epitomized the failure of mourning due to these causes. In his address to the nation delivered on the very day of 9/11, President George W. Bush stated that "America was targeted for the attack because we're the brightest beacon for freedom and opportunity in the world" and that the terrorists failed to threaten America into chaos. He also stated that America is in "the war against terrorism." These statements were a futile reassertion of the illusion of American invulnerability and a prohibition of mourning in favor of violent military responses to 9/11. American nationalism also underlies Bush's official naming of September 11 as "Patriot Day." The victims were sacrificed because they were at the site when terrorists attacked, which implies that their death had nothing to do with American patriotism. Naming September 11 as Patriot Day was an act of imbuing the absurdity of the victims' death with a false meaning and an act of forgetting the non-American victims. The failure of the work of mourning of 9/11 consisted in the inability to recognize human vulnerability and interdependence and the inability to mourn not only American victims but also non-American victims killed in 9/11 and the War on Terror. A meaningful and significant mourning could be possible when we realizes that all human beings are exposed to one another and their lives are interdependent on one another. September Eleventh Families for Peaceful Tomorrows well demonstrated this kind of mourning. When most Americans supported violent retaliations, Peaceful Tomorrows made pleas for nonviolent responses to 9/11. Turning their grief into action for peace, its members work "to create a safer and more peaceful world for everyone," not only for Americans. Their effort to mourn in meaningful and nonviolent ways delivers the message that a disaster like 9/11 should not happen anywhere.
