  • 숲길은 산림휴양서비스의 주요한 축으로 기존의 정상정복형 등산문화에서 벗어나 숲길이 가진 자연 및 역사문화자원을 이용한 다양한 활동에 대한 국민의 요구와 수준도 동시에 높아지고 있다. 따라서 각 숲길 특성에 따른 이용행태를 분석하여 이용유형에 적합한 방향으로 숲길의 관리 및 운영, 휴양서비스 제공이 필요하다. 본 연구는 접근성, 물리적 속성 등에 있어 차이를 보이는 북한산 둘레길, 울진 숲길, 지리산 둘레길을 대상으로 진행하였다. 연구결과 숲길 이용객의 인구통계학적 특성, 탐방동기, 이용행태 등에 있어 전반적인 특성을 도출하였고 숲길에 따른 차이를 확인하였다. 북한산 둘레길은 중 노년층의 이용이 많고 등산, 트레킹 및 건강프로그램을 선호하며 인근주민의 가벼운 산책코스로써 이용이 두드러진다. 울진 숲길은 일부러 시간을 내어 방문하는 유형이 많았고, 트레킹 외에도 다양한 체험활동에 대한 요구가 높은 것으로 나타났다. 지리산 둘레길은 젊은 층의 이용이 많고, 트레킹에 대한 선호와 보행편의성에 대한 요구가 높아 다른 숲길에 비해 걷는 것 자체를 목적으로 이용하는 경향을 보였다.

  • 본 연구는 2011년 산불피해지인 울진과 영덕지역 산불피해지를 대상으로 산불 피해강도의 공간 자기상관성 검증에 목표를 두고 수행되었다. 자기상관성은 산불 피해지의 현장조사, 피해지 모니터링 등 샘플링의 적정 이격거리 설정과 자료의 독립성 검증 측면에서 매우 중요하다. 산불 피해강도 측정을 위해 SPOT영상을 이용하여 NDVI 값을 계산하였으며, 5000개의 지점들을 GIS상에서 랜덤으로 대상지에 분산 배치시키고 지점별 NDVI 값을 샘플링하였다. 공간 자기상관도는 Moran's I값과 Variogram 모형을 이용하여 분석하였다. 분석결과 Moran's I 값이 울진의 경우 0.7745, 영덕의 경우 0.7968로 나타나 강한 공간 자기상관이 존재하는 것으로 분석되었다. Variogram 및 Lag class 별 Moran's I값 변화에 기초하여 도출된 적정한 샘플링 이격거리는 울진의 경우 566-2,151 m, 영덕의 경우 272-402 m 범위에서 상관도의 정도에 따라 다른 이격거리를 적용하여야 할 것으로 분석되었다. 이격거리를 획일적으로 적용하는 것 보다 Anisotropic 분석결과를 기초로 하여 상관도가 높은 지역에서는 크게, 반면 낮은 지역은 상대적으로 작게 유동적으로 적용하여야 효과적일 것으로 판단된다.

  • In order to clarify the relation between sea breeze penetration and Planetary Boundary Layer development in southeastern part of the Korean Peninsula, several numerical assessments were carried out using atmospheric numerical model WRF(Weather Research and Forecasting). Compared with onset time of sea breeze at eastern coast area(Uljin), the time at southern coast region(Masan) with complex costal line tend to delay for several hours. The penetration patterns of sea breeze between two coastal regions are some different due to the shape of their coastal line and back ground topography. Intensified valley wind due to high topography of lee side of Uljin can help penetration of sea breeze at early time. So penetration of sea breeze at early time often prevent PBL to develop at Uljin and lower PBL height last for a day time. But because of late penetration of sea breeze at Masna, PBL Height dramatically decrease after 1500LST. The distribution of front genesis function based on the heat and momentum variation are explained obviously the sea breeze penetration patterns and agreed well with the PBL height distribution.

  • The relationship between the distribution of sea surface temperature(SST) and dinoflagellate(Cochlodinium polykrikoides) bloom areas were studied. The SST data were derived from the infrared channels of AVHRR(Advanced Very High Resolution Radiometer) sensor on NOAA(National Oceanic and Atmospheric Administration) 12 and 14 satellites during 1995-1998. The initial water temperature at C. polykrikoides bloom was about 21${\circ}C$ at the coastal areas of the South Sea and along the shore of the East Sea of Korea during the summer season of 1995. The northern limit of red tides was coincident with that of 21${\circ}C$ isothermal line in the East Sea. The red tides that initially bloomed at the coast of Pohang on September 21, 1995 moved to the coast of Uljin on September 26, 1995. The skipped appearance of the red tides in the areas between Pohang and Uljin was due to the East Korean Warm Current, which was moving offshore from Pohang to approach to Uljin. The cold water which was formed by tidal front in the western coast of the South Sea and by upwelling water from deep layer in the southeastern coast of the Korean peninsula played a role in blocking the spreading of red tides during summer season in 1997 and 1998. In conclusion, the distribution of red tides appeared to be dependent on the initial water temperature at red tides bloom. The SST at the red tides varied from 21${\circ}C$ to 25${\circ}C$; 21${\circ}C$, 23${\circ}C$, 24 and 24-25${\circ}C$ in 1995, 1996, 1997 and 1998, respectively.

  • This study analyzed the community structure of macrobenthic organisms in the subtidal area suffering under the influence of thermal discharge from the Uljin nuclear power plant during 2012-2013 and reviewed the temporal change in the faunal composition of the macrobenthic community using data from previous studies since the start of the plant operation in 1989. A total of 319 species were collected in 2012-2013, with a mean density of $3,330ind./m^2$ and a mean biomass of $131.96g/m^2$. These results were similar to those obtained in 2006-2007. The dominant species were not different from each other before and after the power plant operations began, but the faunal density near the power plant drainage port was significantly higher compared to those densities obtained from other stations. Spiophanes bombyx and Polydora sp., which is known as a pollution indicator species, was dominant only in the drainage port area. The study area consisted of two subregions with different macrobenthic communities depending on the water depth, which was similar to the results of the 2006-2007 survey. The macrobenthic community structures before and after the operation of the power plant in the coastal area were not changed, but there were seasonal differences in the long-term macrobenthic community structure which were strongly related to the thermal discharge from the power plant.

  • Cytogenetic and hematological analysis was performed in peripheral blood from the Korean native goat bred in the nuclear power plant (Wolsong and Uljin) and control area. The frequency of micronuclei (MN) in peripheral blood lymphocytes from goat was used as a biomarker of radiobiological effects resulting from exposure to environmental radiation. An estimated dose of radiation was calculated by best fitting linear-quadratic model based on the radiation-induced MN data over the range from 0 to 4 Gy from the goat lymphocytes with in vitro irradiation. MN rates in goats from the Wolsong and Uljin nuclear power plant, and control area were 9.60/1000, 6.83/1000 and 9.88/1000, respectively. There were no significant differences in MN frequencies and hematological values in goats between nuclear power plant and control area. High level of platelet in the goat from Uljin nuclear power plant was observed, which seemed to be related to the goat management.

  • 동해안 울진 지역 천부 지하수의 수리지구화학 자료에 대하여 지구통계 분석(이원배치 분산 분석, 군집 분석, 요인 분석)을 수행함으로써, 수질 자료와 오염 특성의 시간적.공간적 변화 양상을 규명하고 대수층에서 일어나는 주요 반응을 고찰하였다. 이원배치 분산 분석 결과, 광역적 수질 특성은 8개 수계분지를 따라 유의한 공간적 변화를 보여주지 않았으나, Ca, HCO$_3$,SO$_4$등 일부 이온종은 수계분지별로 의미 있는 변화를 나타내었다. 시료 채취시기에 따른 계절 변화는 SO$_4$를 제외하고는 인지되지 않았다. 그러나 군집 분석 결과, 수리지구화학 특성의 변화는 해안으로부터의 거리에 따라 아주 잘 설명될 수 있음을 지시하였다. 요인 분석 결과, 연구 지역 천부 지하수의 수리지구화학 특성은 다양한 요인에 의해 지배됨을 확인하였다. 중요 순서로 그 요인을 나열하면, 1) 물-암석 반응(주로 탄산염 광물의 용해), 2) 바다에서 기원한 해염의 혼입, 3) 비료와 각종 농화학 약품에 의한 오염으로 밝혀졌다.

  • This study is to evaluate economic effect of the creation project of snow crab, Chionoecetes opilio, spawning and habitat ground in Uljin and Youngdeok county. The main results of this study are summarized as follows: first, 14,400 million won was invested in the creation project cost of Chionoecetes opilio spawning and habitat ground of Uljin and Youngdeok County from 2015 to 2020. Second, the creation project of Chionoecetes opilio spawning and habitat ground directly provides fishing benefits, festival benefits, research and development benefits and employment benefits. Third, on the basis of above benefits, the creation project of Chionoecetes opilio spawning and habitat ground has net present value of 29,900.53 million won, internal rate of return 16.9%, and benefit-cost of 2.91 under a 4.5% social discount rate. Also, the creation project creates 195 jobs. This indicates that the creation project of Chionoecetes opilio spawning and habitat ground not only contributes to the increase in the income of coastal fishery and fishing villages but also to the job making. The result of this study provides useful information to policy makers or project managers as it shows that the project to create spawning and habitat ground should be carried out in consideration of the resource and biological characteristics of individual fish and that economic assessment logic should also be developed based on this. Also, it proves that the project to create a snow crab spawning and habitat ground is a national and local infrastructure project that increases the actual fishing income in the region. At the same time, it maintains the reproducibility function of most fish species, along with enhancing the people's benefits such as fishing village tourism and marine product consumption. Moreover, it provides useful information on budgeting for the continuous development of snow crab spawning and habitat ground in the mid to long-term.

  • This study attempted to grasp the status and perception of Uljin Geumgangsong by grasping mass media issues and user perception using big data, and to present basic data when constructing monitoring using user perception by examining the establishment relationship of agenda setting from a time-series perspective. The results of collecting and analyzing text data that can identify mass media and visitor awareness are as follows. First, both mass media and visitor keywords were related to the importance of the value and meaning of Uljin Geumgangsong. Second, in the case of the connection network, Geumgang Pine Agriculture was centered, but in the case of difference in perception between mass media and visitors, such results were derived due to the object of interest. Third, in the case of the connection relationship structure, the connection strength was strong because there were many overlapping contents of mass media. Fourth, as a result of the centrality analysis, both mass media and visitor-aware keywords were positively recognized as spaces created and maintained through institutional support, and objective perception could be grasped by finding hidden keywords. Fifth, as a result of time series analysis, it was possible to grasp the flow through the issue keywords that appeared by period, and unlike the past, it was recognized as a place for tourism and travel. Finally, as a result of examining whether the agenda setting is consistent, there is a mass media influence, so it is thought that more diverse and more information and publicity are needed by utilizing it.

  • 경상북도 울진 보암광상 일대에서 리튬 페그마타이트와 관련된 화성암체의 분포를 파악하기 위해 중력탐사를 실시하고, 주변 지질 및 광체와의 공간적 관계를 연구하였다. 중력탐사 결과 보암광상 주변은 상대적으로 낮은 중력이상을 나타내고 있다. 보암광상은 남서-북동 방향으로 길게 분포하는 화성암체(분천화강편마암)와 남동쪽의 율리층군 및 원남층군, 동서 방향의 장군석회암층 및 동수곡층 퇴적암과 만나서 이루는 남서-북동 방향의 중력이상 경계 인근에 위치하고 있다. 이러한 남서-북동 방향의 서쪽 경계가 상대적으로 뚜렷하기는 하지만, 이외에도 광상 주변으로 동쪽과 남쪽 경계에서도 상대적으로 낮은 중력이상이 둘러싸고 있기 때문에 이곳에서도 주변으로 지표에 드러나지 않은 화성암체가 분포하고 있을 수 있다. 중력탐사를 통해 추정되는 잠두 화성암체의 분포 특성은 추후 리튬 페그마타이트의 분포와 규모를 예측하는데 유용한 자료로 활용될 것이다.
