The purpose of this study was to analyze the Jeju beach science camp program and to survey the participating students'' preference levels for the activities included therein. The camp programs were analyzed on the basis of the standards set for the HASA curriculum. The program's "manipulatory skill" area included many manipulatory and creative activities while the "inquiry area" included many basic and integrated inquiry activities. It was also indicated that the "knowledge area" included many activities appropriate for understanding concepts and principles while the "attitude area" included many activities appropriate for stimulating curiosity and enjoyment. Thus, it could be seen that the areas stipulated for the HASA curriculum were considerably consistent with the purpose of the science camp. The participating students showed preference for manipulatory and creative activities included in the program. They also preferred basic, inquiry level activities included under the area of "inquiry skills." It was identified that the students most preferred the conceptual stage included under the area of "knowledge" where they were required to grasp the common characteristics of events, things, and phenomena, as also the enjoyment stage included under the "attitude" area, where they were required to participate in pleasant science activities. These findings indicate that science camp programs should be composed of manipulatory and creative activities as well as activities that aim at basic research and the understanding of concepts.

In this study, the projected land use area in 2030 for major crop production was estimated in Jeju Island using land cover map, and corresponding agricultural water demand for 40 sub-regions was quantitatively assessed using the future climate change scenario (RCP 4.5). Estimated basic unit of water demand in 2030 was the highest in the western region, and the lowest in the eastern region. Monthly maximum agricultural water demand analysis revealed that water demand in August of 2030 substantially increased, suggesting the climate of Jeju Island is changing to a subtropical climate in 2030. Agricultural water demand for sub-region in 2030 was calculated by multiplying the target area of the water supply excluding the area not in use in winter season by the basic unit of water demand, and the maximum and minimum values were estimated to be $306,626m^3/day$ at Seogwipo downtown region and $77,967m^3/day$ at Hallim region, respectively. Consequently, total agricultural water demand in Jeju Island in 2030 was estimated to be $1,848,010m^3/day$.

Storm surge height in the coastal area of Jeju Island was examined using the Princeton Ocean Model(POM) with a sigma coordinate system. Amongst the typhoons that had affected to Jeju Island for six years(1987 to 2003), the eight typhoons(Maemi, Rusa, Prapiroon, Olga, Yanni, Janis, Gladys and Thelma) were found to bring relatively huge damage. The storm surge height of these typhoons simulated in Jeju harbour and Seogwipo harbour corresponded relatively well with the observed value. The occurrence time of the storm surge height was different, but mostly, it was a little later than the observed time. Jeju harbour showed a higher storm surge height than Seogwipo harbour, and the storm surge height didn't exceed 1m in both of Jeju harbour and Seogwipo harbour. Maemi out of the eight typhoons showed the maximum storm surge height(77.97 cm) in Jeju harbour, and Janis showed the lowest storm surge height(5.3 cm) in Seogwipo harbour.

We have done the input-output analysis to see the over all impact of flounder industry of Jeju region on the domestic economy of Korea. To do the input-output analysis, we have constructed the data set for the input-output table by using the existing data set in the "2003 input- output table of Jeju regional area" published by the joint work of Jeju branch of Korea bank and the Jeju Development Institute, together with some raw data provided by Jejudo Marine Fish-Culture Cooperative. We have also produced input coefficient of flounder industry by making flounder industrial sector exogenous, separated from intermediate demand. To summarize our empirical results, the inducement effect of production, value added, and employment of Jeju flounder aquaculture industry are 300 billion won, 116 billion won and 1,800 people respectively. In conclusion, the results of this study suggest flounder industry of Jeju region contributes powerfully to not only Jeju economy but also all over the Korea economy.

The purpose of this paper is to estimate economic value of multi-functionality roles including landscape and so on, which grassland in Jeju possesses, using Dichotomous Choice Contingent Valuation Method (DC-CVM). Grassland is life cultural heritance of regional residents in Jeju. It has functions like development of favorable landscapes, maintenance of cultural heritage, and recreation/relaxation. Expectation from regional visitors shows that the existence and inheritance value of grassland is higher than we expected. According to the research that we had done from the people that had agreed to contribute grassland. moreover the public commercial value of grassland was not only $397{\sim}419$ billion won but also it will increase an economic gain in every year in Jeju. Therefore, preserving grassland that has multi-functional roles and values can lead to huge economic value in the future in Jeju. Moreover, farm households which are located in the grassland conservation area would be supported $15{\sim}31$ billion won in every year for grassland conservation but it is only $4{\sim}8%$ of the economic value of grassland i.e. $3,971{\sim}4190$ billion won. Thus, grassland preservation policy and plan can raise green-tour commercial value of Jeju area as a long-term inside measurement. Those will have to be propelled continuously.

The coastal village in Woljeong-ri, Jeju is highly preferred by tourists because of its unique natural landscape different from inland areas. Especially, the number of buildings in the coastal area of the village is increasing due to escalating commercial value. Buildings are densely developed, along the seaside, resulting in privatization of coastal landscape. This results in blocking of landscape and psychological exchanges between the coastal village and coast. This study analyzed the actual conditions of coastal landscape before and after 2010, when the number of tourists and demand for development were increased in the coastal area of the coastal village in Woljeong-ri, Jeju. In this study, open index, visible horizontal index, elevation angle, elevation blockage and visible facade index were used to compute objective indicators of coastal landscape status. The analysis reveals visible facade index, a complex landscape assessment indicator, was increased by 7 times after 2010 as compared with before 2010. As such, there are many coastal villages in Jeju similar to Woljeong-ri that have a high landscape value and are in need of management. A comprehensive measure including a system for management of coastal landscape is urgently required to create narrative landscape in Jeju.

Though numerous drilling has been performed in Jeju Island for development of ground water, the wells are mostly located along the coast lines or at low altitude area, and can hardly be found on the mid-mountain area. Two-dimensional magnetotelluric (MT) surveys have been carried out to cover the lack of geological Informal ion on the mid-mountain area and to figure out any possible structures or evidences for deep geothermal energy remained. Two-dimensional (2-D) inversion of MT data for four survey lines surrounding the Halla mountain show a thick layer having around 10 ohm-m in the depth of a few hundred meters throughout the survey area, which can be considered as the unconsol idated sedimentary layer. And they also show a conductive anomaly extending to more than 2km depth at the central part of each survey lines, which can possibly be related with old volcanic activities during the formation of Halla Mt.. Further seological/geophysical investigations should be followed.
