Underground air is a special energy source in Jeju and distributes lava cave, pyroclastic, open joint, and crushing zone. A possible area to utilize underground air is 85% of Jeju except to the nearby area of Sambang Mt. and 25m high coastal area from sea level. In Jeju, underground air is used for heating agricultural facilities such as greenhouse cultivated mangos, Hallbong and mandarin orange, pigsty, mushroom cultivation house, etc. and fertilizing natural $CO_2$ gas by suppling directly into agricultural facilities. But this heating method causes several problem because the underground air has over 90% relative humidity and is inadequate in heating for crops. Mangos are the most widely grown tropical fruit trees and have been cultivated since 1993 in Jeju. In Jeju, the cultivating area is about 20ha and amount of harvest is 275ton/year in 2010. In this study, the heat pump system using underground air as heat source was installed in mangos greenhouse which area is $495m^2$. The capacity of heat pump system and heat storage tank was 10RT, 5ton respectively and heating effect and heating performance of the system were analysed.

Due to the influence of Han-la Mountain which is located at the center of Jeju Island, a radar blind sector has been appearing in the south-east, low-altitude area of Jeju Island. Thus, the region is perilous for aircraft using surveillance in this area with the existing radar equipment that is currently available. In addition, as the popularity for domestic leisure aviation is on the rise, the safety in low-altitude area should be guaranteed. Where not only IFR flights but also VFR flights are mainly used. Therefore, immediate measures to the present state of radar blind sector in Jeju Island should be taken into serious account. Regarding the circumstances, this study's purpose is to help secure the aviation safety in Jeju region by analyzing the current air traffic surveillance system in Jeju Island and comprehending its vulnerable factors. Moreover, this study compares secondary radar surveillance system, ADS-B and MLAT(Multilateration) system with factors based on the guidance materials from ICAO Asia and Pacific region office to suggests an adequate surveillance technology considering the regional characteristics of Jeju.

Since Jeju island has depended a water resource on the underground water because of a poor development of the surface flow, Jeju island is in need of the surface resource development to prevent the future shortage of the underground water due to excessive development and use of it. The study shows that the SWAT model(continuous rainfall-runoff model) is applied to estimate the outflow in the drainage watershed area, where it has been urbanized through the change of the land, such as a tourism development, cultivation, housing, and impervious layer road development. Near watershed area in Jeju island, weather and topographical SWAT input data were collected, and compared the outflow change of past and present.

Universities are essential in the educating medical school students and create an excellent educational environment for them. We checked the status of personnel turnover at a local medical school to determine the form of entry into the workplace after resignation. According to their intention, the total number of resignations was 54, with individuals being 42.22±5.92 years old (32-64 years old) and having 5.53±4.20 years of service. Resignations under 3 years were 20, and under 15 years or more were nine. By year, the number of professors resigned the most at 11 in 2020 and seven in 2022. Regarding present employment after resignation, 28 individuals (51%) moved to other universities or university hospitals, eight (14%) to general hospitals, 15 (27.8%) to clinics or employment, and three (5.6%) elsewhere. As a result of the analysis, by dividing into the metropolitan areas including Seoul, the area excluding the metropolitan area, and the Jeju area based on the area where a bachelor's degree was obtained, 65.5% and 42.9% of the metropolitan and non-metropolitan area were transferred to universities and university hospitals, respectively. Further, the Jeju area was employed in general or private hospitals. The resignation of a professor from a local medical school varies slightly depending on the demand for medical care in other regions, including metropolitan areas, but tends to continue. Therefore, it is necessary to determine directions for continuing education.

In order to propose basic references for the policy making of fishing vessel fishery by Jeju Special Self-Governing Province, we have obtained the basic productivity through analyzing operating days and catches of 16 sample fishing vessels registered in Aewol port, the north of Jeju island in the year of 2011. In addition, to compare with the basic productivity of southern sea area in the Jeju island, that of 7 sample fishing vessels registered in Kangjung port was used. Around Aewol port, average operating days during the main catch period from July to October were over 15 days a month. A average daily catch of fishing vessels was minimum 21.0 kg in May and reached to maximum 54.5 kg in December, showing U-shaped catch pattern through the year. The trend formula of the average daily productivity (y) depending on a tonnage (x) of fishing vessels around Aewol port was described by the equation, y = 18.867 ln(x) + 11.001, and that around Kangjung port in the year of 2009 was understood to be y = 23.271 ln(x) + 25.715. As a result, it seemed that the productivity of fishing vessels around Kangjung port, operating in the southern sea area of Jeju Island, was much greater than that of fishing vessels around Aewol port in the northern sea area of Jeju Island. Especially, that of fishing vessels less than 10 tons was 35-40% more.

Rainfall, on Jeju Island varies regionally in relation to Mt. Halla with higher rainfall within southern area and lower in western area, and its variability is expected to expand according to the climate change scenario. Non-parametric trend analysis for rainfall, using both historic (1971-2010) and simulated (2011-2100) data assuming the A1B emissions scenario, shows regionally increasing trends with time. In perspective of agricultural land use, area for market garden including various crop types with high water demand is increasing over the Island, especially in the western area with lower rainfall compared to southern area. On the other hand, area for fruit including mandarin and kiwi with low water demand is widely distributed over southern and northern part having higher rainfall. These regional disparity of water demand/supply may be more affected by extreme events such as drought and heavy rainfall that has not yet been considered. Therefore, it is necessary to make policies for water resource management considering both demand and supply in different regions with climate change impacts over Jeju Island.
