I would like to suggest a solution to the problem of aircraft battalion helicopter noise complaints. Among the noise evaluation units, the unit that meets the military helicopter noise evaluation is analyzed and selected to scientifically and reasonably resolve the conflict between residents in the neighboring area and the aviation battalion. Helicopter noise is one of the important problems causing pollution in various pollution problems in the area around the aircraft battalion. The rational and planned process of aircraft battalions will be a way to address aircraft noise pollution.

본 연구는 서해에 위치한 영광 연안해역의 해양수질환경 및 해저퇴적물 환경을 파악하여 기초자료로 제공하고자 한다. 영광 안마도 인근 해역의 21개 정점을 선정하여 2020년 7월에 조사를 실시하였다. 표층해수는 고무 용질의 소형바스켓, 저층은 Van Dorn 채수기를 이용하여 채수하였고, 퇴적물은 Van Veen grab sampler로 채취하였다. 분석항목은 수온, 염분, DO, COD, 영양염류 등 13개의 항목이며, ‘해양환경공정시험기준(해양수산부, 2019)’에 준하여 분석을 실시하였다. 수온은 21.20 ~ 24.20℃, 염분은 31.35 ~ 32.53 psu, 수소이온농도 는 7.62 ~ 8.06, 투명도는 0.20 ~ 3.10 m, 부유물질 농도는 47.00 ~ 455.20 mg/L, COD의 경우에는 0.42 ~ 3.78 mg/L, Chl-a는 0.70 ~ 5.51 μg/L, 용존 무기질소는 0.28 ~ 4.17 uM, 인산은 0.24 ~ 1.14 uM, 규산 규소는 16.28 ~ 35.35 uM, 총 질소는 0.186 ~ 0.542 mg/L, 총 인의 경우 0.037 ~ 0.111 mg/L 의 범위를 나타내었다. 퇴적물 COD의 경우 일본수산용수기준치인 20 mg/g-dry(일본수산자원보호협회편, 2000)보다 낮은 값을 나타내었다. 또한 주성분 분석을 실시하여 해역의 특성을 파악하였다.

This study was conducted to investigate the effects of underwater noise caused by pile driving during marine construction on fish. In this study, the three gray rockfish were released about 1 km away from the construction site of wind power generation on July 18, 2018 and traced using two acoustic telemetry techniques. The behavior of the fish was analyzed by calculating the moving distance, swimming speed and direction of the gray rockfish. In the results of the acoustic tracking using the ship, the rockfish moved about 2.11 km for about two hours at a speed of 0.28 ± 0.14 m/s (0.94 TL/s). The bottom depth of the trajectory of the rockfish was 1.0 ± 0.6 m on average. There was a significant directionality in swimming direction of the gray rockfish, and there was no significant correlation between the swimming direction and tidal current direction. Moving distance during 5 minutes (5MD) during pile driving and finishing operations between rock surface and bedrock were 0.94-0.96 times (76.0-77.0 m) and 1.81-2.73 times (146.0-219.5 m), respectively, compared with no pile driving. This study is expected to be used as a basic data of fish behavior research on underwater noise.

The purpose of this study was to determine changes in neighborhoods due to the development of residential districts around Jangchungdan(獎忠壇) altar in Seoul from the 1920s to the 1930s. In the Joseon Dynasty, this area was a protected and sacred area to honor the spirit. The reputation of the area, however, turned into the place to play and take a rest and neighborhoods around Jangchungdan altar were developed as high-grade residential districts with the impression of suburbs during the Japanese colonial period. Residential districts were formed with the destruction of the Hanyang City Wall and the privatization of nation-owned forest, which were physical and symbolic boundaries of Seoul in the Joseon Dynasty.

우리나라 남해안의 대표적인 패류양식해역 중에 하나인 고성만 주변 표층 퇴적물 중 유기물과 중금속의 분포 및 오염현황을 이해하기 위해 입도와 총유기탄소(TOC), 총질소(TN), 중금속 9종(As, Cd, Cr, Cu, Fe, Hg, Mn, Pb, Zn)에 대해 조사하였다. 고성만 주변 퇴적 물은 세립질의 점토(clay)와 니(mud)로 이루어져 있었다. 유기물과 중금속은 만의 입구쪽에서 안쪽으로 갈수록 상대적으로 높은 농도를 보 였다. 특히, 퇴적물중 유기물 및 중금속의 분포와 C/N 비(5-10)를 고려하였을 때, 고성만 퇴적물 중 유기물은 해역 자체 내 생물체에 의해 생성된 해양기원성 유기물의 영향을 크게 받고, 중금속은 만 주변 혹은 만내 산재해 있는 인위적인 오염원의 영향을 크게 받고 있는 것으 로 파악되었다. 4 가지 퇴적물 오염평가 방법을 이용하여 고성만의 중금속 오염현황을 살펴본 결과, 고성만 퇴적물은 전 해역에 걸쳐 중 금속에 대하여 약간 오염된 상태였으며, 만의 북쪽과 북동쪽의 일부 해역은 퇴적물의 중금속 오염도가 높아 퇴적물에 서식하는 저서생물 에 큰 위해를 줄 수 있는 상태인 것으로 나타났다. 따라서, 고성만 주변 퇴적환경 개선을 위한 체계적인 관리계획의 수립과 함께 지속적 인 양식활동 및 양식생물의 안전성 확보를 위한 오염물질에 대한 집중적인 모니터링 연구가 병행되어져야 한다.

We performed a survey for flavivirus infection and distribution of Aedes albopictus that known as Zika and Dengue virus vector using black–light trap and BG-sentinel trap around urban area in Korea. Mosquitoes were collected in 27 cities during March to November (twice a month) year 2016. Total numbers of mosquitoes collected 102,102 including 19 species 8 genera during collecting period. Total 21,467 Ae. albopictus was collected that 20,961(24.3%) by BG-sentinel trap and 506 (3.2%) by Black-light trap in urban area. Trap index(trap/night) of Ae. albopictus was showed highest in Hamyang (TI:992.3) and lowest in Taebaek (TI:0.3) there was only collected by Black-light trap. A total of 894 pools from all collecting Ae. albopictus were performed a Flavivirus detection. Flavivirus was not detected during study period. This study may provide basic information for surveillance of imported diseases (include Zika virus) and vectors in Korea.

The goal of this master plan is to utilize the historical and cultural landscape resources of Deokjin park, with a thousand years of history, to improve the park’s value, promote the creative development of the historical and cultural landscape, increase the number of tourists, and tourists’ experience elating to traditional culture in the northern district of Jeonju, Korea. To establish master plan, this study analyzed the location, natural environment, and human environment of Deokjin park. The target of this study was limited to the area surrounding Deokjinji within Deokjin park. In order to reflect visitors’ opinions, a survey was conducted relating to the tourism resources around Deokjinji. “Masterpiece of the world! Deokjin park” was selected as a vision statement for the park. The theme of the master plan for the area surrounding Deokjinji is “Pure love that has bloomed for a millennium in Deokjinji,” with the motifs of millennial history and lotus flowers. The development strategy includes thematizing the love of Deokjinji over a thousand years, strengthening the connections with nearby resources, and specializing in the nightscape and nighttime activities. This study suggested the following as facilities for year-round tourism: a traditional dike to reinforce the historic nature of Deokjinji; a performing ferryboat that connects Deokjinji with Jeonju Pansori (traditional dramatic songs); a water lily greenhouse and a botanical garden of sweet-flags/lotuses, thereby using lotuses, as the representative resource of Deokjinji. In particular, the dike around Deokjinji has been designed as the millennial love dike trail, taking into account the historic nature and structural significance based on its thousand-year history and its unique curved shape.

Calpuff 역모델링 기법을 이용해 산출된 자료는 오염물질 발생량을 예측할 수 있으며, 여러 가지 자료 비교를 통해 감축 가능성 및 목표 수립이 가능해졌다. 본 연구에서는 동해항 주변지역을 대 상으로 Calpuff 역모델링 기법을 이용하여 대기 중 미세먼지 저감량 설정하기 위한 기초자료 구축에 목 적을 두었으며, 모델링을 이용한 동해항을 포함한 5개 지역 배출농도 산출결과는 다음과 같다. 대기환경기준인 50 ㎍/㎥을 적용하여 대상 지역별 허용배출량 산출 결과 site-D에서 가장 많은 4.95 ㎍/㎡·S의 배출량 저감이 요구되었으며, 4.95 ㎍/㎡·S의 배출량을 감소시킬 경우 영향예측지점(동해하수 종말처리장)의 PM10 평균 예측농도는 42.6 ㎍/㎥로 감소될 것으로 나타났다. site-A(동해항)에서 배출되는 오염물질만을 적용하여 모델링 진행 결과 동해항 주변 민가의 기여농도 는 평균 40~50 ㎍/㎥으로 나타났으며, 배경농도를 고려하면 대기환경기준인 50 ㎍/㎥을 상회 할 것으 로 예상됨에 따라 더 이상의 오염물질 배출량은 허용되지 않을 것으로 판단된다. site-B는 상가와 나대지로 차량 통행과 나대지에서 비산되는 먼지로 인해 0.11 ㎍/㎡·S의 배출량 저감 이 요구되었으며, site-C와 E는 오염물질 저감량은 발생하지 않았으나 지속적인 관리가 요구된다.
