This study attempted to estimate the amount of expenditure per capita of visitors to the Mongsanpo fishing village tourism festival, and quantitatively measure how much the festival contributes to the local and national economy through input-output model. The analysis data used 302 questionnaires, excluding missing questionnaires, surveyed on festival visitors from April 21 to May 7, 2018, during the 9th Mongsanpo port webfoot octopus and seafood festival. The main results of this study can be summarized as follows. First, analyzing the average expenditure per person of festival visitors, it shows that the average one-person festival visitor consumes KRW 129,519: entertainment costs KRW 5,672 (4.4%), accommodation costs KRW 16,860 (13.0%), food costs KRW 74,791 (57.7%), transportation costs KRW 21,646 (16.7%), shopping costs KRW 6,788 (5.2%), and other costs KRW 3,762 (2.9%). Among the expenditures of festival visitors, the proportion of food expenses was the highest, and transportation costs and accommodation costs were in order. Second, based on the actual expenses spent by visitors at the fishing village tourism festival, the direct economic effect of the Mongsanpo fishing village festival was estimated be approximately KRW 14.8 billion. Third, as a direct and indirect economic impact effect of the Mongsanpo fishing village tourism festival in 2018, the amount of production induced in the local and national economies was estimated at KRW 33.3 billion, and the amount of value-added inducement was estimated at 11.3 billion won, and employment inducement reached 272 people, which is considered to contribute greatly to the national economy. This study quantitatively analyzes and provides the extent to which the fishing village tourism festival using local specialized fisheries directly or indirectly contribute to the local and national economy. Thus, it is expected to serve as useful information by providing basic information on business feasibility required for budgeting for local fishing tourism festivals.

To evaluate the relative ecological quality of Taean coastal areas in terms of various seaweed community indices, seasonal samplings were taken at the Hakampo, Padori, Chaeseokpo, Mongsanpo and Bangpo shores from March 2006 to January 2007. A total of 105 species were identified; species richness ranged from 37~72 species spatially and from 65~75 species seasonally over the study period. Coarsely-branched seaweeds were dominant in functional group and ESG I (ecological state group I) made up 61 species (58.10%) of the identified macroalgae. The average seaweed biomass at the five study sites was $56.63g\;dry\;wt./m^2$ (range, 36.66 at Hakampo $-73.89g/m^2$ at Mongsanpo). Seaweeds were generally abundant in mid and low intertidal zone. Corallina pilulifera, Ulva australis, Sargassum thunbergii, Neorhodomela aculeata, and Symphyocladia latiuscula were the dominant species across all five study sites. Species diversity was between 1.24~2.30, while species evenness was between 0.40 and 0.61. The dominance index ranged from 0.43 at Padori to 0.64 at Mongsanpo. Given the community indices and shore descriptions, the five study sites were divided into two groups based on ecological quality: moderate (Chaeseokpo and Mongsanpo) and good (Hakampo, Padori and Bangpo).

This research aims to analyze spectral reflectance of intertidal zone and its changes under various environmental conditions. We sampled sand of Mongsanpo tidal flat, Korea, and measured its spectral reflectance by using a spectroradiometer under various water contents, compositions and granularity. We also simulated the reflectance of Landsat 7 ETM+ and compared it with an actual satellite data. Five locations were selected for sampling from the coastline towards the ocean. Grain size diminished stepwise from the coastline to ocean direction, while spectral reflectance differed with wavelength. Water contents lowered the overall reflectance especially at the water absorption bands. Spectral reflectance data were then converted into the simulated one by using Landsat 7 ETM+ spectral reflectance function to be compared with the actual Landsat 7 ETM+ images. It showed the decrease of the spectral reflectance due to the increase of moisture contents from seashore towards the ocean. It is shown that Landsat 7 ETM+ imagery can be efficient to extract moisture contents in the tidal flat while compositional analysis needs satellite sensors with much higher spectral resolution.

In this study, we analyzed ridge-runnel structure and ripple marks by using Envisat ASAR, JERS-1 SAR images and in-situ data in Mongsanpo intertidal flat located in Taean-Gun, Korea. A group of light-and-dark lines parallel to the shoreline, alternating 3-5 times, were observed in the intertidal flat in Envisat ASAR images. The patterns are related to ridge-runnel structure in the intertidal flat exposed to air. Well-drained runnels, typically with ripple marks, showed strong backscattering while runnels submerged by surface water or ridges, typically smooth with no ripple, have weak backscattering coefficients in Envisat ASAR images. In JERS-1 SAR images, however, the backscattering was very low on the entire intertidal flat and no ridge-runnel structure could be observed. The wavelengths of ripple marks measured from in-situ observations have ranges from 4 to 10 cm that satisfies the Bragg scattering condition of the 1st-order in Envisat ASAR images operating in C-band, but not in JERS-1 SAR that used L-band. Through this study using SAR images, we could successfully analyze the sedimentary conditions of intertidal flats with ridge-runnel and ripple marks which are not easily observed by optical sensors. It is expected that the results of this study with SAR images will contribute to the sedimentary research over intertidal flats.
