GNSS Services and Applications are today in permanent evolution in all the market sectors. This evolution comprises: ${\bullet}$ New constellations and systems, being GALILEO probably the most relevant example, but not the only one, as other regions of the world also dwell into developing their own elements (e.g. the Chinese Beidou system). ${\bullet}$ Modernisation of existing systems, as is the case of GPS and GLONASS ${\bullet}$ New Augmentation services, WAAS, EGNOS, MSAS, GRAS, GAGAN, and many initiatives from other regions of the world ${\bullet}$ Safety of Life services based on the provision of integrity and reliability of the navigation solutions through SBAS and GBAS systems, for aeronautical or maritime applications ${\bullet}$ New Professional applications, based on the unprecedented accuracies and integrity of the positioning and timing solutions of the new navigation systems with examples in science (geodesy, geophysics), Civil engineering (surveying, construction works), Transportation (fleet management, road tolling) and many others. ${\bullet}$ New Mass-market applications based on cheap and simple GNSS receivers providing accurate (meterlevel) solutions for daily personal navigation and information needs. Being on top of this evolving market requires an active participation on the key elements that drive the GNSS development. Early access to the new GNSS signals and services and appropriate testing facilities are critical to be able to reach a good market position in time before the next evolution, and this is usually accessible only to the large system developers as the US, Europe or Japan. Jumping into this league of GNSS developers requires a large investment and a significant development of technology, which may not be at range for all regions of the world. Bearing in mind this situation, MAGIC appears as a concept initiated by a small region within Europe with the purpose of fostering and supporting the development of advanced applications for the new services that can be enabled by the advent of SBAS systems and GALILEO. MAGIC is a low cost platform based on the application of technology developed within the EGNOS project (the SBAS system in Europe), which encompasses the capacity of providing real time EGNOS and, in the near future, GALILEO-like integrity services. MAGIC is designed to be a testing platform for safety of life and liability critical applications, as well as a provider of operational services for the transport or professional sectors in its region of application. This paper will present in detail the MAGIC concept, the status of development of the system within the Madrid region in Spain, the results of the first on-field demonstrations and the immediate plans for deployment and expansion into a complete SBAS+GALILEO regional augmentation system.

World Heritage is a very important heritage that is worth protecting and handing down to future generations. In Korea, which has a long history and culture of 5,000 years, Seowon is a great advantage in that it can develop tangible and intangible Neo-Confucian ideas shared in China and East Asia, and preserve and experience them as a unique cultural resource of Korea until the present day. In order to encourage the direct experience of this long-standing cultural heritage, the government supports the national treasury and seeks to expand the demand for tourism. Accordingly, in this study, an analysis was conducted on program satisfaction, participation, and activation plans. As a result, it was found that value to see and value to experience must coexist in order for our world heritage, which requires comprehensive and continuous management and operation, and lacks accessibility, to become a tourist attraction. Also, for this purpose, promotion and development of differentiated tourism experience contents should be carried out first.

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.

The study was conducted to understand the meaning of the voluntary service experience of Korean-Chinese who living in South Korea and examine the reason of participating in voluntary activities. 8 people participated in the study, who come from volunteering groups in a Korean-Chinese compact community. Data were collected through in - depth interviews and participation observation. The collected data were categorized and analyzed according to Giorgi's hermeneutic phenomenological research method. As a result of the analysis, three sets of themes were drawn on the nature of their volunteering experience. Through their volunteer activities, they have been improving their images that have been damaged and stigmatized by the mainstream society. Through their volunteer activities, they have improved their self-esteem, got more information about the society and better adapted to Korean society. Moreover, through their volunteer activities, they have increased their sense of responsibility for Korean society and redefined their position in Korea. Given this, they expect the possibility of becoming a global citizen for the future. The meanings of volunteer experience of Chinese Koreans have been examined and discussed in this study, which indicated that the activation of the volunteer activities of migrants contributes positively to the integration of multicultural society.

In the Web 3.0 era, the third generation of web technologies that uses blockchain technology to give creators ownership of data, metaverse is a crucial trend for developing a creator economy. Web 3.0 aims for a value in which content creators are compensated from participation without being dependent on the platform. Blockchain NFT technology is crucial in metaverse, a vital component of Web 3.0, to ensure the ownership of digital assets. Based on the theory that investigates the concept and characteristics of metaverse, this study identifies five features of the metaverse based NFT art ①'Continuity', ②'Presence', ③ 'Concurrency', ④'Economy', ⑤ 'Application of technology'. By focusing on metaverse based NFT art <Hybrid Nature> case study, we analyzed how the concepts and characteristics of the metaverse and NFT art were reflected in the work. This study focuses on the concept of NFT art, which is emerging at the intersection of art, technology and industry, and emphasizes the importance of finding creative, aesthetic, and cultural values rather than the NFT art's potential for financial gain. It is still in its early stage for academic studies to focus on the aesthetic qualities of NFT art. Future academics and researchers can find this study to gain deeper understanding of the traits and artistic, creative aspects of metaverse based NFT art.

The purpose of this study was to examine the validity and reliability of the Playfulness Scale for Adults. The Korean version of the Playfulness Scale for adults was developed by Proyer, R.T (2017) to measure the playfulness of adults. To validate the OLIW in Korean, item translation, back-translation, item analysis, and exploratory factor analysis (EFA) were conducted with 406 adults in study 1. Of the results obtained from study1, three items and one factor (7 items) were discarded because they turned out to be improper. In addition, 4 factors that were not the same as the original scale were extracted. This was checked by conducting confirmatory factor analysis (CFA) with 336 adults in study 2. CFA supported the 4 factors structure and all 4 factors showed adequate internal consistency. To check the concurrent validity of the Korean adults playfulness scale, correlation analysis with the APS, SMAP, PSYA, and NEO Personality Assessment was conducted. It showed significant positive correlation to APS, SMAP, PSYA, and showed the similar patterns of correlation with the sub factors of NEO Personality Assessment. Adult playfulness is related to the participation frequency of leisure. In conclusion, the Korean version of the playfulness scale for adults is a valid measure of playfulness for adults in Korea. The implications, practical use and suggestions for future study were discussed.

This study was conducted to examine the remuneration curriculum of vocational ability development training teachers and instructors and to examine ways to apply micro credentials. To this end, the current status of the remuneration curriculum of vocational ability development training instructors and instructors at K University's Competency Education Development Institute, the characteristics of micro credentials, and the possibility of linking the remuneration curriculum to micro credentials are as follows. First, most of the recognition of digital certificates was positive for digital certificates such as digital credit, digital badge issuance, and recognition of the recognized qualification process of maintenance education when completing the training course. In addition, as a method of applying micro credentials to conservative education, various cases were proposed to benefit from conservative education, systematization and grading of the qualification process, and credit of the qualification process. Second, as an institutional supplement to enhance the utilization of conservative education using micro credentials, the need to expand NCS-based major conservative education, provide efficient learning contents and learning methods, and set minimum completion time. In addition, the most common response as a way to improve the understanding of teachers and instructors in vocational ability development training was the micro credential promotion plan. Third, in the role of conservative education institutions and vocational ability development training instructors and instructors, conservative education institutions mention maintaining educational quality the most, and active participation was the role of vocational ability development training instructors. Through this study, it is expected to establish a vocational training environment that can enhance expertise and provide a practical portfolio of practical competency history by linking the remuneration curriculum of vocational competency development training instructors and micro credentials.
