Jeju City is one of the cities where decline of old city-center is appearing due to the reduction of residential and floating population. The decline of old city-center of Jeju City has been on the rise since the 1990s, and has been intensifying in the 2000s. Jeju City is currently activating specific policies to ensure activation and diversification of the local commercial area. In this paper, we propose a new method to increase the number of visitors to Jeju-Mokkwana by using Augmented Reality technology for activating commerce of old city-center. Various Augmented Reality contents based on smart-phone are implemented and operated in Jeju-Mokkwana. Also the survey is conducted to 574 visitors who have experienced online/offline promotion for analyzing effects. Survey results show that the proposed method can be effectively used to activate the old city-center by increasing the floating population.

Water management treatment of coastal region has been an important problem in Jeju city since the distributions of pipeline of the pumping system made a bad view in coastal region. To solve the problem, we observed the pipelines that are on the surface around the coastal region from Tapdong to Doduhang. From the observations, we found that Todong and Dodu areas were not unsightliness because the all pipelines were located in underground. However, the other areas, such area Yongdam, Handugi, Yongdam fishing village, had a serious problem for the coastal landscape view. To solve the problem, at we estimated coastal land color characteristics of Jeju city based on the observation of the pipelines. The estimated color panel shows that the green, blue and grey colors are a dominant factors of the Jeju coastal region. Based on the color panel, we proposed two methods, that is, one is a short time treatment, the other is a long time one. The short is based on the colour treatment, which is pipeline colour changing into surround natural one. The long time is the construction plan design method. Although the later method was very useful in Jeju island. However, it takes a lot of time and money. Therefore, in the situation, the short time is the better than the long time one.

The odontogenic cutaneous fistula in facial area is uncommon but, well defined disease. It is difficult to diagnose from the dental origin of cutaneous sinus tract. Most patients may visit to the dermatologists or general hospital without cause of disease. They usually be treated by repeated surgical excisions, biopsies, and antibiotic medications, but suffered from recurrences. We studied odontogenic cutaneous fistula through retrospective study in Jeju Special Self-Governing Province between 1 January 2009 and 12 December 2015. There were 3 males, 5 females from 14 to 78 years old with an average age of 50.4 years old. Only 2 patients felt the toothache, others didn't detect it. They suffered from recurrences and repeated treatments for 3 to 11 months with an average period of 7.9 months. They visited average 2.8 hospitals before a precise diagnosis in a dental clinic. All cases were fully healed endodontic treatment or extraction of origin teeth without recurrences. In conclusion, the cause of cutaneous fistula in facial area can be odontogenic. If dentists or doctors diagnose a patient with cutaneous fistula on face, they should check dental problems or take x-ray views for precise diagnosis. It could be helpful for differential diagnosis.

The storm water management and drainage relation are the key variable that plays a vital role on hydrological design and risk analysis. These require knowledge about spatial variability over a specified area. Generally, design rainfall values are expressed from the fixed point rainfall, which is depth at a specific location. Concurrently, determine the areal rainfall amount is also very important. Therefore, a spatial rainfall interpolation (point rainfall converting to areal rainfall) can be solved by areal reduction factor (ARF) estimation. In mainland of South Korea, for dam design and its operation, public safety, other surface water projects concerned about ARF for extreme hydrological events. In spite of the long term average rainfall (2,061 mm) and increasing extreme rainfall events, ARF estimation is also essential for Jeju Island's water control structures. To meet up this purpose, five fixed rainfall stations of automatic weather stations (AWS) near the "Hancheon Stream Watershed" area has been considered and more than 50 years of high quality rainfall data have been analyzed for estimating design rainfall. The relationship approach for the 24 hour design storm is assessed based on ARF. Furthermore, this presentation will provide an outline of ARF standards that can be used to assist the decision makers and water resources engineers for other streams of Jeju Island.

To analyze human thermal environments in protected horticultural houses (plastic houses), human thermal sensations estimated using measured microclimatic data (air temperature, humidity, wind speed, and solar and terrestrial radiation) were compared between an outdoor area and two indoor plastic houses, a polyethylene (PE) house and a polycarbonate (PC) house. Measurements were carried out during the daytime in autumn, a transient season that exhibits human thermal environments ranging from neutral to very hot. The mean air temperature and absolute humidity of the houses were $14.6-16.8^{\circ}C$ (max. 22. $3^{\circ}C$) and $7.0-12.0g{\cdot}m^{-3}$ higher than those of the outdoor area, respectively. Solar (K) and terrestrial (L) radiation were compared directionally from the sky hemisphere (${\downarrow}$) and the ground hemisphere (${\uparrow}$). The mean $K{\downarrow}$ and $K{\uparrow}$ values for the houses were respectively $232.5-367.8W{\cdot}m^{-2}$ and $44.9-55.7W;{\cdot}m^{-2}$ lower than those in the outdoor area; the mean $L{\downarrow}$ and $L{\uparrow}$ values were respectively $150.4-182.3W{\cdot}m^{-2}$ and $30.5-33.9W{\cdot}m^{-2}$ higher than those in the outdoor area. Thus, L was revealed to be more influential on the greenhouse effect in the houses than K. Consequently, mean radiant temperature in the houses was higher than the outdoor area during the daytime from 10:45 to 14:15. As a result, mean human thermal sensation values in the PMV, PET, and UTCI of the houses were respectively $3.2-3.4^{\circ}C$ (max. $4.7^{\circ}C$), $15.2-16.4^{\circ}C$ (max. $23.7^{\circ}C$) and $13.6-15.4^{\circ}C$ (max. $22.3^{\circ}C$) higher than those in the outdoor area. The heat stress levels that were influenced by human thermal sensation were much higher in the houses (between hot and very hot) than in the outdoor (between neutral and warm). Further, the microclimatic component that most affected the human thermal sensation in the houses was air temperature that was primarily influenced by $L{\downarrow}$. Therefore, workers in the plastic houses could experience strong heat stresses, equal to hot or higher, when air temperature rose over $22^{\circ}C$ on clear autumn days.

Although Jeju is the best cruise Secondary port in Northeast Asia, currently there are no dedicated cruise terminals. The port international passenger terminal opened in 2015 has a ferry terminal for offshore passengers and a cruise passenger function. Jeju Island is therefore constructing a cruise only terminal with the aim of opening in 2018 to meet the growing passenger demand at the Seoguipo civilian and public ports along with construction of a naval base at Gangjeong Port in Seogwipo City. It also plans to build cruise docks and cruise terminals in the Jeju New Port according to the Jeju port construction basic plan. However, during the construction and planning process of cruise terminals in Jeju, the adequacy of the terminal size is being debated and the immigration facilities are being operated. Therefore, the study analyzed the size of terminals and operation of immigration facilities appropriate for cruise passenger demand by investigating the status of cruise related facilities and operation in Jeju area. Based on this, the Commission hopes to explore the rational direction of the cruise terminal plan to revive the cruise industry in Jeju and provide high quality service to cruise passengers.

During the six years from 2006 to 2011, based on a study of projects with an area equivalent to or less than $2,700m^2$ located in Jeju self-governing province, it was shown, through comparison with the pre-existing calculation methods, that there were many problems with the application of the standard cost. Accounting for the uniqueness of Jeju province, the study suggested an alternative method for applying the standard cost, basing it on property usage of either urban area or non-urban area pursuant to the National Land Planning and Utilization Act rather than land type of either mountain area or non-mountain area, with the utilization of T-test and ANOVA raising the reliability of this study.

There are still a number of "olles" existing with traditional alley characteristics in the inner city of Jeju. As a matter of fact, the renovation of old buildings and the protection of alley space are facing a dilemma due to the existence of less than 4m-width-roads in the area of "Mu-geun-sung". This study examines the current status of alley space in "Mu-geun-sung" area; and puts forward to the potential possibility and limitation of alley space regeneration via exploring the applicable scheme of building agreement. In the field survey, a number of regions in inner city of Jeju witnesses the existing majority of invaluable, conventional olles. So as to grasp the feasibility in "Mu-geun-sung" area, we designs a simulating experiment to carry out the Building Agreement; and compares with the current development model in this area. Building Agreement implies to establish gradually a separation of land ownership under the existing unified development of landowners and users, thus to explore a variety of land exploitation systems by separating land ownership and right to use land. As a result, the deterioration of the street landscape results from the increase of building storey numbers. The damages to the surrounding environment brought by the newly built buildings will be minimized as well as keeping the maximum building volume rate. Obviously, these measures will alleviate infringement to the traditional residential sunlight and privacy space effectively, and reduce the pressure from high-rise buildings to the alley space, so that the landscape of the alley will enhance to form a more comfortable alley environment.

The purpose of this study is to introduce the storytelling project for conservation and improvement of rural tourism. So, in this study, the current Jeju Batdam and storytelling planning are examined and the storytelling project presented in planning is also examined. And this study propose the storytelling implementation through the case study related in jeju. Its findings are as follws: 1) Storytelling exhibits principles of narrative structure(exposition, complication, climax and falling action) in various fact, and has shown tendency to structuralize a story. 2) It can be said that storytelling is deeply related with people's associations of their inner mind. 3) In order to convey a story in a more convincing way, storytelling a naming strategy based on a rhetorical technique, which has been shown to positively influence creating unique Jeju Batdam area.
