The purpose of this study was to investigate the relationship between academic efficacy and vocational identity according to the private and public self-consciousness of college students. For this purpose, 263 college students completed the questionnaires on self-consciousness, academic efficacy and vocational identity. The collected data were analyzed by using SPSS 22.0 and AMOS 22.0. As a result, both the private and public self-consciousness had a significant positive correlation with vocational identity and academic efficacy. The private and public self-consciousness had different effects on vocational identity(career exploration, career commitment, and career reconsideration) through academic efficacy. Specifically, the private self-consciousness had a direct effect only on the career reconsideration among the factors of vocational identity. Public self-consciousness was indirectly related career exploration, partially mediated by academic efficacy, whereas the association between public self-consciousness and career commitment was fully mediated by it. Based on these results, implications for career education and counseling in convergence era were discussed and suggestions for further study were included.

This paper intends to explore the social and cultural implications of convergence media, based on Goffman's situational approach. The situational segregation of regions makes us to re-interpret the current private and public spheres and helps us to reveal the principle and structure hidden in the new middle region. An environment of convergence media is nullifying the separation of private and public spheres, while letting a new middle region appear.

In current public blockchain, any node can see every blocks, so that public blockchain provider transparent property. However, some application requires the confidential information to be stored in the block. Therefore, this paper proposes a multi-layer blockchain that have the public block layer and the private block for confidential information. This paper suggests the requirement for encryption of private block. Also, this paper shows the t-of-n threshold cryptosystem without dealer who is trusted third party. Finally proposed scheme satisfies the requirements for encryption and fairness.

The purpose of this study is program development for efficient medical institution management and finding comprehensive measures to increase the credibility of medical institutions. For this purpose, a survey on medical service satisfaction was conducted for elderly people aged 65 or older living in four other areas. The results of the analysis were as follows: First, the survey participants had higher confidence in private medical institutions. Second, there was no relationship between the reliability of public and private medical institutions and the selection of medical institutions. Third, the environment of the survey subjects was related to the selection of medical institutions. The credibility of the surveyed public and private medical institutions affects the selection of medical institutions, and the economic power and understanding of the medical institutions also influence the selection of medical institutions.. Therefore, it is suggested that public medical institutions need to improve the satisfaction of medical services in the future, and management efficiency of public medical institutions in addition to private medical institutions is urgently needed.

This study is related with support system plans of public-private convergence for emergency recovery services to fire victims. The current issues are analysed from the condition and problem analysis results of emergency recovery activities for fire victims. And building plans of an integrated support system based on the government and private sector cooperation are proposed. Overall, the system shows that the government is responsible for the functionality of management and supervision for the system operation, and the private is responsible for the functionality of specialized agencies for practical emergency recovery. Consequently, support system plans include with infrastructure maintenance of laws and regulations, contracting-out of the support system, stable supply of operating budget and function strengthening of public-private convergence for emergency recovery. Especially, plan for stable supply of operating budget in detail including with establishment of the fund and self-financing composition of private corporations for emergency recovery services is proposed. The results of this study will lead strengthening of fire safety welfare and social safety nets at future.

Purpose: As most defense technologies are classified as confidential, the corresponding International Patent Classifications (IPCs) require special attention. Consequently, the list of defense-related IPCs has been managed by the government. This paper aims to evaluate the defense-related IPCs and propose a methodology to revalidate and improve the IPC classification scheme. Methods: The patents in military technology and their corresponding IPCs during 2009~2020 were utilized in this paper. Prior to the analysis, patents are divided into private and public sectors. Social network analysis was used to analyze the convergence structure and central defense technology, and association rule mining analysis was used to analyze the convergence pattern. Results: While the public sector was highly cohesive, the private sector was characterized by easy convergence between technologies. In addition, narrow convergence was observed in the public sector, and wide convergence was observed in the private sector. As a result of analyzing the core technologies of defense technology, defense-related IPC candidates were identified. Conclusion: This paper presents a comprehensive perspective on the structure of convergence of defense technology and the pattern of convergence. It is also significant because it proposed a method for revising defense-related IPCs. The results of this study are expected to be used as guidelines for preparing amendments to the government's defense-related IPC.

The cloud has already become the core infrastructure of information systems, and government institutions are rapidly migrating information systems to the cloud. Government institutions in several countries use private clouds in their closed networks. However, because of the advantages of public clouds over private clouds, the demand for public clouds is increasing, and government institutions are expected to gradually switch to public clouds. When all data from government institutions are managed in the public cloud, the biggest concern for government institutions is the leakage of confidential data. The public-private-partnership (PPP) cloud provides a solution to this problem. PPP cloud is a form participation in a public cloud infrastructure and the building of a closed network data center. The PPP cloud prevents confidential data leakage and leverages the benefits of the public cloud to build a cloud quickly and easily maintain the cloud. In this paper, based on the case of the PPP cloud applied to the Korean government, the concept, architecture, operation model, and contract method of the PPP cloud are presented.

The purpose of this study is to compare the educational needs of public officials and private employees for health and welfare in order to improve education program. Data were collected from 2,290 public officials and 1,991 private employees and were analyzed using frequency analysis and independent sample t-test. Private employees recognized that education and training are more enough than public officials. In addition, private employees took the gathering training classes more than public officials. Private employees reported that they are more satisfied than public officials with regard to leader consideration, peers' will of participation and institutional conditions. However, public officials reported that they are more satisfied than private employee officials with regard to the degree of sharing of information and education for new policies. Public officials preferred three or two days of training, but private employees preferred one or two days. Both public officials and private employees preferred gathering training classes and blended learning as an effective education type. Based on this research, invigoration of health and welfare education and the management of its plan were discussed.
