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 examines the concepts and policy factors regarding gender-mainstreaming strategies and urban areas that have been discussed in the fields of international norms and development cooperation from the perspective of the Mexican government. It analyzes how gender-mainstreaming strategy is integrated and realized through Mexican law and key programs carried out by Mexico City. Through a literature review, this study builds upon previous research and theoretical discussions. In fact, Mexican federal government is considered to have successfully achieved "gender institutionalization." Within the framework of the law and institutions, the programs promoted by Mexico City aim to realize women's rights and meet their needs in the metropolis, while emphasizing a wider participation by citizens to realize these urban rights. In particular, the government of Mexico City is expanding on policies and programs that focus on strengthening the financial autonomy of women by understanding women's vulnerabilities as inequalities arising in the areas of the economy, space, and time.

Nosong-dong is used to be center of the administration, education and transportation in Jeonju. It has ironically been the location of the city's prostitution quarter 'called Seonmichon'. This place is recently selected as an area of urban regeneration by Jeonju. The project has involved numerous programs which gradually transfer this place for the women's rights and arts. This paper focuses on exploring the socio-cultural meanings of a community museum, an archive for gender equality, and an exhibition site for local artists. The Seonmichon quarter has long been stigmatized as an area of ill repute and regarded with contempt by the surrounding neighborhood. It is space where polarized interests are entangled. City authority has tried to reflect this by presenting a variety of perspectives on the Seonmichon district. An initiative of the community museum has been its hosting of several exhibitions around the themes of women's rights and community arts. The most remarkable aspect of the exhibitions that have taken place in the heart of the Seonmichon district has been the active participation of local community residents as a catalyst for progressive social change. The paper's overall purpose is to provide an introduction and analyze the process of development of the exhibition initiative, and further examine the social role and meaning of the community museum in Nosong-dong, as well as its future tasks and directions.

By delivering effective, in-situ conservation of biodiversity, OECMs can contribute to sustaining existing biodiversity values and improving biodiversity conservation outcomes. In this study, for the reporting of OECMs required by Kunming-Montreal Global Biodiversity Framework, the site-level assessment of the Korea National Arboretum and Buffer Zones were conducted using the assessment tool of IUCN. The site-level assessment was carried out in three steps(step 1: screening, step 2 : consent for full assessment, step 3 : the full assessment). It was found that the criteria were satisfied except for the consent for full assessment, sustainability of governance and management arrangements, and the equity of governance and management. Although the governing authority, rights-holders or any other stakeholders could be identified, the step of acknowledging and agreeing to the full OECM assessment was not possible because the governance was not established. As a result of the assessment of equitable governance and management in the aspect of recognition, procedure, and distribution based on criterion(the equity of governance and management), it is judged that more specific measures are needed in the aspect of recognition. And in the aspect of procedure, there is no legal basis for participation in governance and collection of opinions, so it is judged that there is a limit to listening and reflecting the opinions of stakeholders. In the aspect of distribution, it is necessary to further confirm whether it provides direct benefits to rights-holders such as landowners in the region. And it is necessary to prepare specific criteria to assess the important biodiversity values. Therefore, in order to promote OECM reporting in the future, it is necessary to conduct detailed research on various types of governance establishment and operation plans that can establish the basis for recognizing and agreeing to OECM assessment, specific criteria and reasonable measures to judge equity, and important biodiversity value.

Following the signing of the Paris Agreement on Climate Change (UNFCCC, 2015), the world is expanding greenhouse gas reduction activities through comprehensive participation that includes not only developed countries but also developing countries. Major countries around the world are placing high expectations on the effectiveness of total carbon emissions regulation through the carbon emissions market. However, in order to obtain carbon credits, third-party verification is required based on quantitative carbon reduction data. Accordingly, in this paper, we developed an AIoT high-efficiency street light for carbon emissions and conducted a performance analysis study to measure the luminous efficiency of the lighting fixture. To obtain carbon emissions rights, we used high-efficiency LED PKG, developed our own high-voltage PFC, and developed high-efficiency lighting fixtures capable of communication. For communication, the 2.4GHz LoRa method was adopted between the lighting fixture and the gateway. Lens design was conducted through simulation of Korea Expressway Corporation's standard streetlight types A, B, and C. The performance of the streetlight was verified as being more efficient than other existing products through the measurement of luminous efficiency by an accredited rating agency, and it is expected that carbon emissions rights will be obtained by reducing electrical energy through this.

e-Learning education system as the next educational trend supporting remote and multimedia education. However, the students stay mainly at remote place and it is hard to certificate whether he is really studying now or not. To solve this problem, some solutions were proposed such as instructor's supervision by real time motion picture or message exchanging. Unhappily, as you can see, it needs much cost to establish the motion exchanging system and trampling upon human rights could occasion to reduce the student's will. Accordingly, we propose the new intelligent system based on face recognition to reduce the system cost. The e-Learning system running on the web page can check the student's status by motion image, and the images transfer to the instructor. For this study, 20 students and one instructor takes part in capturing and recognizing the face images. And the result produces the prevention the leave of students from lecture and improvement of attention.

The purpose of the study was to conduct an empirical study on the scope and level of social exclusion experienced by persons with psychosocial disabilities. The Wave 6 data of the Panel Survey of Employment for the Disabled were used to investigate the current status of social exclusion in life areas including income, education, work, housing, health, social network, social participation, and discrimination (N=4,161). A series of logistic regressions were executed, with the psychosocial disability(PD) group being the reference; the reverse odds rations of different disability groups were compared against the PD reference group (OR=1). The results showed that compared with all others, the PD group was about 2 to 11 times more likely to have risks in income, work, and housing; and that compared to other groups except for the autism/developmental disability group, they were about 6 to 10 times more likely to have risks in social network, social participation and discrimination. In conclusion, the authors urged the need for legal mandates to have community based mental health services and welfare services for the disabled more available to the PD groups and the necessity to eliminate various discriminatory legislations that are violating human and social rights of the persons with PDs.

"Positive Influence(PI)" of popular star has recently emerged as a social concern, but the lack of prior research has led to confusion over its concept and range of activity. On this point, this study carried out to lay the groundwork for discussions on the systematization of related theories, focused on identifying the current situations by analyzing articles for 15 months from January 2019 to March 2020 when related reports were in full swing. As a result of the analysis of the remarks from the entertainers mentioned in the articles, they were not clearly aware of the concept while doing good deeds under the name of PI in light of the study outcome by Aegean and Singer(2013). The motivations for good deed were classified into six types, including difficulty empathy, fandom reward, participation urge, nidana emphasis, experience subjugation, and memory evocation in the order of frequency of cases. Specific behaviors of PI were followed by donations of money and valuables for 54.4 percent, participation of social agendas for 14.0 percent, volunteering for 13.2 percent, joining campaign for 11.4 percent, other good deeds for 4.0 percent, and philanthropy for 3.0 percent. In occupational analysis, the concentration of donations was also evident. Their activities in the fields of human rights sensitivity, environmental protection and self-management, which are expected to have great effects with their influence, have been extremely poor. The results of the study first require academia to establish a interdisciplinary concept for PI. It also suggests that entertainers and their agencies should take far more strategic approach to evolve the PI event in a way that utilizes the advantages of each job group, such as actors, singers and comedians, and expands the diversity of areas.

In Korean society, church once witnessed the period of its being considered light and salt. After the liberation, Korean church bestowed Jesus Christ's love to underprivileged neighbors in the industrialization process and organized practical participation activities for human rights and democratization. Nonetheless, church was sunken into quantitative growth without having qualitative growth. As church was cited as the epicenter of the spreading COVID-19, the image of selfish church has started receiving attention and there has appeared a criticism for immoral church tendency, which brought low trust about church. These things are resulted from church's failure to undertake its role with responsibility, in society. Such as this, church has lost its identity as the model of the Kingdom of God. In such a situation, church needs to remind itself of the enlightenment of the Ecumenical Movement, in order to recover trust and perform its mission. The Ecumenical Movement means accomplishing unification of the universe through a renewed church. This movement is aimed to create the earth as 'where humans can stay' and to consider the sustainability of mankinds. This purpose of this study is to examine political activities conducted for responsible participation in the church world and to find the way for church roles in this world. This researcher will attempt to investigate educational methods to help Christians in this world take full responsibility given to them, through an educational discussion about Christianity made in this context. This educational attempt means, in other words, political affairs also.
