The purpose of this study is to investigate the characteristic changes of the Changma season in the 2000s. To accomplish this goal, we have used daily rainfall data collected over nearly 40 years (1971 to 2010). The average summer precipitation data including the Changma season were collected from 16 weather stations that are placed across the three major regions (i.e. central region, southern region, and Jeju region) as Korea Meteorological Administration divided. These precipitation data were analyzed to find out characteristic changes of the Changma season. Results of the precipitation data comparison among the major regions that, monthly average precipitation in the central region was the highest in July; its precipitation tended to increase from May to September. In the southern region, the precipitation amount was lowest in June and tended to increase in May, September, and August. In the Jeju region, the precipitation has been the highest in June and July for the past 30 years, whereas September has been highest month in the last 10 years. The precipitation amount in the Jeju region decreased both in June and July, whereas it tended to grow in May, August and September. A correlation coefficient formula by Karl Pearson has been used to find out correlations between the Changma season and the precipitation of the major regions in 2000s and normal years. It was found that the correlation coefficient has decreased from 0.723 to 0.524 in the 2000s (2001 to 2010) compared to normal years (1971 to 2000).

Tourism Industry can be treated as means for activating the economy of regions and must be considered as new alternative. As this trend, recently. the interest of tourism area connected with health industry is increasing gradually. And so, this study investigated the domestic abroad cases and established the promotion model of health tourism through experts' opinion to push ahead health tourism as strategy industry of Jeju region. Also this study proposed the planning to improve the competition ability of Jeju region by executing the fundamental research through the survey focused on tourists.

Jeju Special Self-Governing Province are trying every effort to be presented as an International Free City with unique combination of history, culture and landscape, This research focuses on the analysis of characteristics we can find in buildings in Jeju province. The main purpose is to provide basic and informative materials for the landscape formation of Jeju by investigating current status of buildings in Jeju province. This research divides Jeju province into 34 areas and categorizes buildings by use. 2,973 cases in total are collected and analyzed their architectural features. A basic analysis of the collected data is conducted in the first and the second stages. And In the third stage, 505 cases whose addresses can be identified are selected for the in-depth analysis of the registered building data on architecture year, building area, and total area. These data are analyzed by the categories of region, year, and size for the study of general characteristics of buildings in Jeju. The results show that territoriality is weak because of the simplicity of building layout on the streets. Exterior form of buildings, streetscape image, and overall city image are tedious and boring because of the lack of the variety of facade and exterior finishing materials.

This study introduces one specimen each of the genera Gymnopilus, Marasmius, and Mycena as an unrecorded species found in the Hwasun Gotjawal and Jeju Gotjawal Provincial Park of the Hangyeong-Andeok terrain, South Korea. Morphological analyses of macroscopic and microscopic features, and molecular analysis of the nuclear ribosomal internal transcribed spacer region were conducted to identify the specimens. Our results indicated that the newly identified specimens were Gymnopilus dilepis, Marasmius tenuissimus, and Mycena seminau. Here, we describe these newly identified mushroom species and provide baseline data on their diversity in Gotjawal, South Korea.

With regard to Jeju Special Self-governing Province's natural-spa tourist spot development project, this paper has investigated the natural environment of Sehwa-Songdang Lave Region. According to this study, the cave consists of many small caverns with poor cave formations. Due to unfavorable climate conditions in the cave, in addition, hydrological environment is also very poor. In terms of vegetation, the cave shows the general vegetation environment of Jeju.

This study aimed to analyze the profitability and economic feasibility of hairtail trolling line gear that was developed for the last 3 years (2015-2017). The new fishing gear technology development was accomplished to solve the current problem of fishermen shortage in hairtail targeting fisheries in Jeju region. Results indicated that the profitability of developed hairtail trolling line fishery was estimated to be 36.1 % which would be higher than that of other hairtail targeting fisheries in Jeju region. In addition, as an economic feasibility, the net present value and the internal rate of return of a 20-year cash inflow and outflow were evaluated to be 400.2 million won and 66.9 %, respectively. However, sensitivity analyses of main variables showed that the profitability and economic feasibility would be vulnerable to catch amount and market condition changes.

The elevated water storage tanks highly crowded in the western region in Jeju island is an important landmark of Jeju island. This study examines the reasons that the elevated water storage tanks appeared in a high density. After examination, this study found that the elevated water storage tanks formed under the influences of climate, hydrogeologic structure, soil, topography and land use. In particular, the elevated water storage tanks in Jeju are closely related to the crapping system with which water has to be supplied using sprinkler due to well drained soil and hydrogeological characteristics. The results of this study show that elevated water storage tank landscape in the western region of Jeju island is an agricultural landscape particularly made in the course of farmers' adaptation to the natural environment of Jeju island.
