  • This study was performed to evaluate the adaptability of farm field soil transplanting and habitat growth in inland and seashore areas of Artemisia capillaris in South Korea. In habitat, Artemisia capillaris was distributed both in the inland and seashore area as hemicryptophyte, and it grows individually on the slope of the open sunlight. The inland and seashore soils of habitat was the slightly acid and weakly alkaline, respectively. Plant height was 55.6 cm, and it was higher in inland than that of the seashore area. The stem and branch number was less in inland than that of the seashore area. Flowering period was mid-August, and flower of inland blossomed early 1 ~ 3 days than that of the seashore area. The flowering and fruiting rate was slightly lower in inland than that of the seashore area. After transplanting of Artemisia capillaris, plant height was 71.7 cm, and it was higher 16.1 cm than that of the habitat. The stem and branch number was more than that of the habitat, and flower blossomed early 3 ~ 4 days than that of the habitat. Transplanting survival rate was 85.1%, it was slightly higher in inland than that of the seashore area.

  • This study was conducted to evaluate the status of habitat distribution, environmental characteristics and plant species growing with Lonicera japonica in its habitats. In the distribution of plant coverage below 30%, it was 84.6% in the inland area and 80.7% in the seashore area. There was similar coverage in both inland and seashore areas. But the average relative coverage in the seashore area was 26.1%, which is a little higher than that of the inland area (22.5%). In the habitats, both inland and seashore areas showed a high distribution ratio below 10 degrees. But among them, inland areas showed a high distribution ratio (62.4%) below 10 degrees, which was about twice as much as the seashore areas (32.2%). Habitat distribution was most often found on the southern slopes in both inland and seashore areas. The average soil pH of Lonicera japonica habitat was 5.2 in the inland areas and 6.9 in the seashore areas. Also, the seashore areas showed little content of $P_2O_5$, but high content of K, Mg, Na on the other hand compared to the inland area. Miscanthus sinensis was the highest importance value (16.4) among plants growing with Lonicera japonica in their habitats in both inland and seashore areas. But in the inland areas, Artemisia princeps showed the highest importance value, and Miscanthus sinensis was the highest in the seashore areas.

  • The tallest culm length was observed in Geonganghongmi cultivar grown in coast area, and culm length was always taller in coast area than that of inland area among these three red rice cultivars. However, number of tiller per rice plant was not affected by different cultural area. Number of spikelets per panicle was much more increased in inland area. Regional difference in number of spikelets per panicle was only observed in Jeongjinju cultivar. Among these red rice cultivars, the highest brown rice yield was Jeongjinju rice cultivar having 702kg in inland area and 692kg in coast area, respectively. The $L^*$ values, which expresses the brightness, were in the range of 36.3 ~ 36.7, 36.7 ~ 37.0, and 38.7 ~ 39.6 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. The $a^*$ values, which expresses the redness positively and greenness negatively were in the range of 12.3 ~ 12.8, 12.2 ~ 12.3, and 12.1 ~ 11.9 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. In addition, the b values, which expresses the yellowness positively and blueness negatively were in the range of 13.8 ~ 14.0, 13.6 ~ 13.5, and 14.9 ~ 14.7 in Jeogjinju, Hongjinju, Geonganghongmi rice cultivars, respectively. Anthocyanidin content ranged 524 to $610{\mu}g/g$ dry weight basis. Cyanidin content was 11.4 to 14.0 times higher than that of delphinidin under coast and inland area. Among these rice cultivars, anthocyanidin content was always higher in rice cultivar grown at coast area. Highest head brown rice rate was only observed in Geonganghongmi to 95.2 at coast area and 95.4 inland area, respectively. Protein content was always higher in coast area than that of inland area. The lowest protein content was measured in Jeogjinju and amylose content was relatively increased in inland area compared to that of coast area. Consequently, in considered with brown rice yield and pigment content, Hongjinju rice cultivar was recommended in optimal pigment rice cultivar in eastern coast of Gyeongsangbuk-do Province.

  • The atmospheric conditions and the transport mechanism of long-range transport of air pollutants from coastal area to inland area were investigated using regular meteorological data and air pollution data obtatined from the southeastern area of Korea. Daytime temperature over the inland area(Taegu) was higher than that over the coastal area(Pusan) and the temperature difference of about 5~6$^{\circ}C$ when the thermal low most fully developed and the sea level pressure over Taegu was lower than that over Pusan by about 4~5hPa at that time. Therefore this low pressure appeared to the thermally induced low. Air mass polluted from the coastal area during the morning period was transported inland area, at first by the sea breeze and by the large scale wind system toward the thermal low generated in the mountainous inland region. This was explained by the fact that the concentration of air pollutants over Taegu increased throughtout the late afternoon.

  • In urban area, flood risk is getting higher because of inland flood risk has grown up by changing rainfall intensity, rainfall pattern, changing land use and so on. Urban area is needed higher flood protection level to protect accumulated people, buildings and other infrastructures. However, even though former flood protection has focused on overflow from river, there is not a guide line for evaluating proper flood protection level. Thus, it is necessary to protect flood from inland flooding as well as overflow from river and need a proper method to evaluating flood protection level. This study present a method of determining flood protection elevation by using GIS tools for deciding proper flood protection level. The study result may contribute to urban flood protection measures in which inland flood risk increases.

  • The purpose of this study is to analyze the changing housing construction in Jeju-do which is composed of two cities(Jeju-si, Seogwipo-si). The number of indigenous population and migrating population of Jeju-do has been increasing every year because it has more beautiful scenery, interesting culture and a higher ratio of natural green area to urban area than other provinces(inland). More than 70% of population in Jeju-si is concentrated in dong-area. As a result, urban area and commercial area are expanding in entire Jeju-do. On the other hand, green area and non-urban area of Jeju-do are decreasing steadily. And there was a lot of changing during a short of time after 2010 because of internationalization and urban development etc.. This study is an analysis about the changing of housing in Jeju-do by statistical data. As a results of the analysis. I discovered that 1) The supply ratio of available housing in Jeju-do is higher than other inland cities in other parts of the country. 2) Housing constructing is influenced by moving-in and moving-out population. 3) There are more detached houses in Jeju-do than apartments. The opposite phenomenon occurs in other provinces (inland cities). However, the number of detached houses is gradually declining in Jeju-do since 2000. 4) Most detached homes in Jeju-do have an area of $60m^2{\sim}90m^2$. Most apartments have smaller areas than $60m^2{\sim}90m^2$. Seogwipo has homes with a larger area than Jeju-si. 5) The ratio of concrete structure houses is increasing at high speed because of constructing of apartment buildings, on the other hand, the ratio of brick structure house is decreasing gradually. Finally, Even though Jeju-do has different from housing culture of inland, it is changing slowly like inland housing types.

  • The influences of inland pollution sources nearJeokyang and Jangpoports following rainfall events on the bacteriological water quality and safety of commercial shellfish were investigated in the Changseon area, Korea. Stream flow rates exhibited 1.9- to 5.7-fold increases after rainfall events and then fell to 68~81% of that level after 24 h. The calculated impact area of inland pollution sources was 0.47 $km^2$ in the Jeokyangport area and 0.27 $km^2$ in the Jangpoport area at 24 h following 11 mm of rainfall. When the flow rate of inland pollution increased, the level of male-specific bacteriophage (MSB) decreased, and no MSB could be detected in seawater samples, whereas 30 PFU/100 g was detected in shellfish samples. Fecal coliform levels in seawater and shellfish samples did not exceed their respective tolerance levels (4.5 MPN/100 mL) and 130 MPN/100 g, respectively and thus complied with the standard for approved shellfish growing area. The sanitary conditions of areas adjacent to Jeokyang and Jangpoports under conditions of rainfall below 29 mm met the criteria for approved growing area under the United States National Shellfish Sanitation Program and the EC Regulations.

  • The influences of inland pollution sources because of rainfall events on the bacteriological water quality in Geoje Bay, a major shellfish production area in Korea, were investigated. The sanitary status of sea water and shellfish after rainfall events was also evaluated. The flow rates of 13 streams around Geoje Bay showed 6 to 7-fold increases after 15 to 21 mm of rainfall. Peak pollution was observed in the Naegan Stream, the Gandeok Stream and the Seojeong Stream. The calculated impact area of inland pollution sources was 3.1 $km^2$ immediately after 15 mm of rainfall and expanded to 3.5 $km^2$ after 24 hours. These calculations of impacted area matched results from fecal coliform analyses with sea water. The distance between the major pollution source in the bay (the Gandeok Stream) and the station with the worst bacteriological water quality immediately after 15 mm of rainfall, which was below the Korean standard, was 0.8 km in a straight line; this distance increased to 2.0 km after a period of 24 hours. The area impacted by inland pollution sources after a 15 mm rainfall event was wider than after a 21 mm rainfall. Although the flow rate from inland pollution sources was higher, the concentration of fecal coliform in the discharged water was lower after higher rainfall events. These observations corresponded with the results of fecal coliform analyses with sea water samples. According to the evaluation of the influences of inland pollution sources and fecal coliform analyses on sea water and shellfish samples in Geoje Bay, pollutants from inland sources did not reach the boundary line of the shellfish growing area after rainfall events of 15 or 22 mm. The bacteriological water quality of the shellfish growing area in Geoje Bay met the Korean standard and US NSSP requirements for approved shellfish growing areas.
