  • In Hansan Geojeman area, 2,050 ha of shellfish growing area has been designated as shellfish production area for export. The main shellfish species from the designated area is oysters. For the sanitary management of the designated area established in Hansan Geojeman area, bacteriological examination of sea water and shellfish at the sampling stations inside and outside of the designated area were performed from January 2006 to December 2008. The range of fecal coliform of 756 sea water samples at 21 stations located in the designated area were <1.8~>1,600 MPN/100mL. And the range of geometric mean and the estimated 90th percentile of fecal coliform were 1.8~2.9 and 2.7~15.8 MPN/100mL, respectively. Sanitary conditions of the current designated area in Hansan Geojeman meets the required standards of the Fisheries Product Quality Control and National Shellfish Sanitation Program (NSSP, USA) criteria for the approved area. Also, the sanitary status of the shellfish harvested from the designated area met the Korean Shellfish Sanitation Program (KSSP) fecal coliform criterion (<230 MPN/100g). And the human pathogen such as Salmonella spp. and Shigella spp. were not detected from the examined shellfish samples.

  • The sanitary quality of a shellfish-growing area in Gangjinman, Korea, was assessed through a bacteriological examination of seawater form January 2007 to December 2009. The range of the geometric mean (GM) and the estimated 90th percentile for most-probable-number (MPN) values for fecal coliforms in samples collected in the designated area were 2.0-2.4 and 6.1-11.5 MPN/100 mL, respectively. Therefore, the bacteriological quality of seawater in the designated area in the Gangjinman area met the National Shellfish Sanitation Program (NSSP, USA) guidelines for approved areas. Also, the sanitary status of shellfish harvested from the designated area met the Korean Shellfish Sanitation Program (KSSP) fecal coliform criterion (<230 MPN/100 g). However, the degree of bacteriological contamination increased rapidly, and water quality exceeded the criteria for approved areas when large amounts of rain fell before the sampling date. Fortunately, fecal pollutants did not affect the bacteriological quality of a buffer zone established between the shoreline and the designated area. These results indicate that the current buffer zone established around the designated area protects the designated area properly.

  • Background: To confirm whether shellfish are suitable for consumption, the quality of seawater and shellfish in shellfish-producing areas must be assessed regularly. This study was conducted to evaluate the bacterial quality on the Changseon area, containing a designated shellfish-producing area, in Korea during 2011-2013. Result: Even though many inland pollutants near the area were identified, they showed no significant impact on the designated area and the shellfish therein. The concentrations of fecal bacteria in all the seawater and mussel samples from the designated area during the harvesting season were within the standards of various countries. Pathogenic bacteria were not detected in any of the mussel samples. In our previous study, the hazardous metal levels in all the mussels from the same area were also within the limits of different countries. Conclusion: The mussel products in this area are suitable for consumption based on fecal pollution, pathogenic bacteria, and also heavy metals.

  • In this paper, a Doppler radar for a localization of a human motion is demonstrated. In the system, we used a $8{\times}8$ phased array antenna using metamaterial phase shifters for easy and precise control of antenna beam pattern. Scanning area is a circular sector with an inscribed angle of $60^{\circ}$ and a diameter of 45m. This area is divided with 15 designated area and each area is scanned for 0.2 second. When there is a motion in a designated area, we are able to detect a frequency shift due to a Doppler effect. In this way it is possible to detect the location of motion. The experiment shows that 78% of position accuracy. The remaining 22% occurred the surroundings of the designated area.

  • The seawater in the Taean area was surveyed to evaluate the conditions of the bay and compliance with the bacteriological criteria for a designated area for shellfish production for export. Samples of seawater were collected monthly at 34 sampling stations established in the survey area from January 2002 to December 2004. The bacterial density in the coastal area close to a pollution source located to the northeast of the survey area was higher than in the open sea to the west. The bacteriological counts in the water did not change with 16.5mm of rainfall, but increased abruptly after 65.4mm of rainfall. The total coliform and fecal coliform most probable numbers (MPNs) of 1,224 seawater samples in the survey area were <1.8-2,400 and <1.8-790 MPN/100 mL, respectively. The geometric mean and estimated 90th percentile of total coliforms were 1.9-3.4 and 2.7-26.3 MPN/100mL, respectively, and for fecal coliforms were <1.8-2.6 and 1.8-12.0 MPN/100mL, respectively. The bacteriological water quality in the Taean seawater area met the National Shellfish Sanitation Program criteria for an approved area and the Korea Shellfish Sanitation Program criteria for a designated area for shellfish production for export.

  • Bacteriological examination of a 12,700 ha area within Jaranman Saryangdo area, located in Jaran bay and Saryangdo island, was conducted with 35 fixed (designated areas and adjacent areas) seawater sampling stations between January 2006 and December 2008. According to results, the geometric mean range and the estimated 90th percentile range of fecal coliform counts in sea water samples collected in the designated area were <1.8-2.4 and <1.8-8.6 MPN/100mL, respectively. The estimated 90th percentile range of fecal coliform counts in sea water samples collected from 6 sampling stations in the adjacent areas were 6.1-34.6 MPN/100mL. Based on these results, bacteriological water quality of the designated areas in the Jaranman. Saryangdo area meet the NSSP (National Shellfish Sanitation Program) guidelines for approved area. The bacteriological sea water quality in Jaranman.Saryangdo area has been shown to be favorable at all investigated sampling stations except for July and August which coincided with heavy rainfall. In fact, the bacteriological water quality was not affected if rainfall was less than 30 mm rainfall. However, the degree of bacteriological contamination increased rapidly and the water quality exceeded approved NSSP guidelines set for rainfall above 60 mm.

  • The purpose of this study is to evaluate the biotope structure of the city center area of Jung-gu for nature experiences and recreation purposes. Jung-gu is the most extremely and rapidly urbanized area of Daegu. This study was conducted under the assumption that the biotope structure of a city center area would be different from the urban area. The results of this study are as follows: 1) There are 11 biotope type groups as designated as commercial and work-area biotope type group, and 41 detailed biotope types designated as commercial areas with a lack of greenspace biotope type. 2) The commercial and work area biotope type group has the largest area with 34% of the total area, and the square biotope type group has the smallest area with 34% of total area. 3) The result of primary biotope evaluation is that there are 12 biotope types that have greater than third grade, apart from the biotope type of park that includes natural vegetation. The first grade of biotope type has not appeared in this area, however, the fifth grade of biotope type has 20 biotope types with the biotope type of construction work area (JA). 4) The results of the secondary biotope evaluation are 1 biotope for la, 9 biotopes for 2a, 9 biotopes for 2b, 14 biotopes for 2c and no biotope for 2a. This study suggests that a detailed investigation and improvement plan for high-value biotope areas in the city center area must be continued.

  • 교통안전특정해역은 선박사고의 위험성이 특히 높아 정부가 채택한 연안해역을 의미하나 정작 이 곳에서 적용되는 항법에 대하여는 여전히 논란이 있는 게 사실이며 여수VTS 관제구역에 있는 광양만 출입항로에 있어서는 그 적용이 더 난해한 부분이 있다. 따라서 본 연구에 대한 대책으로서 적극적 관제를 위한 교통안전특정해역에서의 항법적용에 대한 통일된 해석과 적용 방침을 마련하고, 나아가서 해사안전법에서의 특별항법 부분을 별도로 분리 입법하는 방법으로 선박교통안전을 향상하고, 선박교통관제사가 적극적인 업무자세로 집중관제의 토대를 마련하는데 조금이나마 기여하고자 한다.

  • 본 연구는 보호지역으로 보호되고 있는 국가지정 문화재중 천연기념물과 명승을 대상으로 현황을 분석하고 이들 문화재를 보호지역 카테고리에 포함하기 위한 기초연구로 연구결과는 다음과 같다. 첫째, 현재 문화재보호법으로 지정 보호되고 있는 자연문화재중 명승과 천연기념물을 대상으로 보호지역 현황을 조사한 결과 명승40개소, 천연기념물 126개소가 보호지역으로 조사되었다. 둘째, 조사결과 자연문화재에서의 보호지역은 마을에서 '당숲', '성황림', '신림(神林)'등으로 오랫동안 마을사람들의 행(幸) 불행(不幸)에 관계된 성스러운 대상이었으며, 물리적 환경뿐만 아니라 문화적 가치와 규범, 토지에 대한 태도와 신앙관 등이 종합적으로 결합된 결과물로써, 주민들로부터 마을을 지켜주는 신성한 장소로 인식되고 있으며, 그 지역의 독특한 민간신앙 등으로 인해 강력한 보호를 받고 있는 것을 알 수 있다. 셋째, 천연기념물 노거수는 점적인 형태로 인식되어 보호지역에 포함하지 못하고 있으나, 보호지역을 중심으로 보호구역을 설정되어 있어 세계보호지역 등재가 가능할 것으로 조사되었다. 넷째, 명승의 자연성지는 IUCN 카테고리의 지정 목적을 달성할 수 있도록 세계보호지역으로 설정함에 있어 명승 내부의 공간별 특성에 따라 자연성지를 비롯한 개별 카테고리를 세분화하여 적용함으로써 세계보호지역으로 관리하여 보호해야 할 필요가 있을 것으로 판단된다.

  • While the zoning system has been developed based on the rationale of separated and specialized land uses to prevent negative externalities in the modern industrial era, the emergence of office-based new industries in the post-industrial era rather encourages mixed land uses to create agglomeration economies. This study aims to find historical basis to justify the reform of zoning system to promote both specialized and mixed land uses. When the zoning system was first introduced in Japanese colonial period by Chosun Planning Ordinance enacted in 1934, Special District within Manufacturing Area, and later within Residential, Commercial, and Mixed Areas respectively was institutionalized for specialized land uses, though it was not actually designated. When City Planning Law was enacted in 1962, Special District was substituted by Exclusive Areas (Exclusive Residential Area, Exclusive Manufacturing Area). Meanwhile Undesignated Area was designated for mixed land uses by Chosun Planning Ordinance, and later it was converted mostly into Mixed Area and partially into Green Area. Finally Mixed Area was substituted by Semi-Areas (Semi-Residential Area, Semi-Manufacturing Area) by City Planning Law in 1962. These demonstrate that Korean zoning system needs to revive the tradition that clearly promoted both specialized and mixed land uses.
