Communal places for parents to take child-care are very important in activating cooperative child-care(CCC). Therefore, Jeju Special Self-Governing Province has been operating Cooperative-Childcare-Places(CCPs) since 2016. This study analyzed the operational status of the CCPs and presented the model type to provide data for the activation of CCC. Qualitative analyses were applied to the results of interviews with 10 staff members. The common task they considered difficult was recruitment, and there was a big difference in the operation of the regular program depending on the competence of the staff in charge. The lack of support systems, such as education and consulting, has made it difficult for the staff to do their work. Additionly, four models of CCPs were found, a resident self-governing type, a workplace type, an institutional type, and a rural complex type. In conclusion, CCP spaces should be planned and facilities created with a focus on the needs of child-care activities. Second, the role of staff in helping to organize the parents' self-governing committee is crucial. Third, it needs to establish a support system to strengthen the capacity of the staff members.

Recently, as the paradigm of regional development has been transformed into characterization, decentralization and cooperation, small and medium scale development is in the spotlight. In particular, as the transfer of planning authority to local governments accelerates, LH is in the process of seeking to transform itself into a system that is in line with local government demand. The purpose of this study is to elaborate the regional pending projects that meet the demand of the region. The Jeju Special Self-Governing Province is the area where land and housing prices have increased more than three times recently, which is the area of interest in recent years due to the various demand for development projects. Another objective is to establish a local government based on LH's system, it is aimed to derive a collaboration method with local government, province corporation and local researchers. The criteria for deriving the cooperation projects between the local government and LH are basically the ones that can be carried out by LH and future-oriented projects. The process of deriving has undergone the process of statutory planning, unscrupulous plan analysis, and consultation of experts' advisory committees. In order to derive the regional cooperation project, four criteria such as local uniqueness, future possibility, business promotion efficiency, and local cooperation project were set. Major projects of the Jeju Special Self-Governing Province are improvement of the surrounding traffic system, construction of the hinterland due to the construction of the second airport, and establishment of Cruise Port(Jeju Port, Seogwipo Port). The role of each entity in the implementation of regional cooperation projects is as follows. Local government should request subsidies for the projects in case of lack of budget support and secure them through competition with other regions. In addition, it should be responsible for the operation and management of the facility once it has been supported and completed smoothly. The Ministry of Land, Infrastructure and Transport affects each region through approval and subsidy of the development plan. After the development project is completed, it evaluates the development project through monitoring and plays a role of continuously improving the system. As a business operator, the provincial corporation will carry out small-scale projects including non-physical projects such as community participation. In the case of LH regional headquarters, the general manager of the region will establish a comprehensive business plan, secure development availability, and carry out large-scale growth promotion projects.

Groundwater is an important water resource that can be used along with surface water. In particular, in the case of island regions, research on groundwater level variability is essential for stable groundwater use because the ratio of groundwater use is relatively high. Researches using artificial intelligence models (AIs) for the prediction and analysis of groundwater level variability are continuously increasing. However, there are insufficient studies presenting evaluation criteria to judge the appropriateness of groundwater level prediction. This study comprehensively analyzed the research results that predicted the groundwater level using AIs for various regions around the world over the past 20 years to present the range of allowable groundwater level prediction errors. As a result, the groundwater level prediction error increased as the observed groundwater level variability increased. Therefore, the criteria for evaluating the adequacy of the groundwater level prediction by an AI is presented as follows: less than or equal to the root mean square error or maximum error calculated using the linear regression equations presented in this study, or NSE ≥ 0.849 or R² ≥ 0.880. This allowable prediction error range can be used as a reference for determining the appropriateness of the groundwater level prediction using an AI.

It is possible to provide Smart Tourism Service through the development of information technology. It is necessary for the tourism industry to understand and utilize Big Data that has tourists' consumption patterns and service usage patterns in order to continuously create a new business model by converging with other industries. This study suggests to activate Jeju Smart Tourism by analyzing Big Data based on credit card usage records and location of tourists in Jeju. The results of the study show that First, the percentage of Chinese tourists visiting Jeju has decreased because of the effect of THAAD. Second, Consumption pattern of Chinese tourists is mostly occurring in the northern areas where airports and duty-free shops are located, while one in other regions is very low. The regional economy of Jeju City and Seogwipo City shows a overall stagnation, without changes in policy, existing consumption trends and growth rates will continue in line with regional characteristics. Third, we need a policy that young people flow into by building Jeju Multi-complex Mall where they can eat, drink, and go shopping at once because the number of young tourists and the price they spend are increasing. Furthermore, it is necessary to provide services for life-support related to weather, shopping, traffic, and facilities etc. through analyzing Wi-Fi usage location. Based on the results, we suggests the marketing strategies and public policies for understanding Jeju tourists' patterns and stimulating Jeju tourism industry.

During the period from 2003 to 2020, a total of 470 Streptococcus species were isolated from farmed flounder in Jeju. Out of 470 isolates, 92 (19.6%) isolates and 378 isolates (80.4%) were identified as Streptococcus iniae and S. parauberis, respectively by multiplex PCR assay. During that period, the percentage of S. iniae decreased from 56.9% in 2003 to 0.0% in 2020 whereas that of S. parauberis increased from 43.1% in 2003 to 100% in 2020. In the PCR assay for serotyping, the isolated S. parauberis showed 3 subserotypes, Ia (34.9%), Ib/Ic (46.3%) and II (18.8%). In 2003 and 2004, serotype II was dominant at 59.1% and 50.0% of isolation rates, however between 2005 and 2009, subserotype Ib/Ic was dominant (57.6%, 86.0%, 84.6%, 57.9%, and 83.3%). After 2010, except for 2015, subserotype Ia was the most dominant one. In the last 3 years (2018 to 2020), subserotype Ia was most abundant (70%), followed by subserotype Ib/Ic (16-30%). Serotype II was not isolated in 2018, but in 2019 and 2020, it showed an increased tendency to 3.4% and 16.7%, respectively. It is believed that continuous monitoring is necessary for research on counter-measures against streptococcosis of flounder.

Jeju Special Self-governing Province continues to try to attract tourists on the basis of an active investment in the tourist industry. But most of the researches and studies on Jeju Tourism were made on a viewpoint of hardware. Therefore, the researches and studies which are related to 'the inclination of tourists who visit Jeju Island', 'the tourist satisfaction by a selection of tourist destination' and 'tourists' activities after the visit to Jeju Island' are insufficient. Accordingly, this study will support a basic datum needed for formulating a policy of Jeju tourism by closely examining the related influences among the Jeju tourists' inclination, their satisfaction and their activities after a tour of Jeju.
