        울돌목 시험조류발전소의 수중소음 특성 연구

        고명권,최지웅,이진학,정원무,Ko, Myungkwon,Choi, Jee Woong,Yi, Jin-Hak,Jeong, Weonmu 한국음향학회 2012 韓國音響學會誌 Vol.31 No.8

        최근 친 환경 발전에 관한 관심이 높아지면서 태양광, 풍력, 조력, 조류 발전에 대한 수요가 점차 증가되고 있다. 이러한 친 환경 발전 방식 중 조석운동에 의한 해수의 흐름을 이용하는 조류발전은 지형적 특성에 의해 강한 조류가 발생하는 지역에서만 사용할 수 있는 특수한 발전 방식이다. 울돌목 해역은 조류 발전이 가능한 매우 강한 조류가 형성되는 지역으로 다른 지역의 해역과 구분되는 특별한 환경을 제공한다. 하지만, 해양에서의 인간의 활동은 수중소음을 야기하여 해양환경에 큰 영향을 미친다. 최근에는 환경영향평가의 중요성이 대두되면서 발전소 가동 시의 소음 특성 분석 및 전파양상 예측에 대한 필요성이 증가하고 있다. 본 연구는 조류발전소의 수중소음 특성을 측정하고 울돌목 해역으로의 전파양상을 모델링 하였다. Recently, as a result of increasing concern about eco-friendly power, the demand for the power stations using environmentally friendly powers such as photovoltaic energy, wind force, tidal power, and tidal current has been increasing worldwide. Among these power stations tidal current power plant requires strong current generated by the topographic characteristics of the ocean floor. Uldolmok waterway producing very strong current is an ideal location for a tidal current power generation. However the occurrence of anthropogenic underwater noise generated by the tidal current power station may affect the marine environment. Therefore, it is necessary to evaluate the noise radiated from the station and predict the range influenced by the radiated noise. In this paper, the measurements of radiated noise spectrum level by the tidal current power station are presented, and the source level per unit area is estimated. Finally, the propagation properties of the radiated noise in the Uldolmok waterway is evaluated from the model simulation using the parabolic equation method, RAM.

        Lichen nitidus(LN) is an unaommon chronic eruption of numerou tiny, discrete, usually flesh colored, shiny papules most cornmonly located on the penis, arms, for arms, and abdomen. It was described by Pinkus, first in 1901. The distribution of LN is most often locaized, but in some cases it may become generalized. A 10-year-old healthy boy was seen by our department because of many flesh colored, discrete, shiny papules on the whole body. The papules are skin colored, pinhcad sized, round, and flat-topped. The lesions appeared first at the age of 9 on the forehead and then neased in the number and extended downward to the neck, trunk, abdornen and both extremities. This case was successfully treated with topical corticosteroid. (Kor J Derrnatol 1994; 32(6): 1107-1110)

        Prurigo pigmentosa is a chronic pruritic inflammatory dermaoss characterized by erythematous papules in a reticulated pattern that resolve leaving a reticulated, mottled hyperpigmentation. Most cases have been reported from Japan. Two cases of prurigo pigmentosa have been reported in Korean women. We experienced a casc of prurigo pigmentosa in a Korean man of 20 years of age. Histopathological findings of reddish papule showed exocytosis, sponsiosis, intraepidermal vesicles, hydropic degeneration of basal cells in the epidermis, and hyphohistiocytic infiltration in the upper dermis. Direct irnmunofluorescence was negetive. Therapy with dapsone, 50 mg given daily, resulted in a rerinable regression of the reddish papules. The daily dose of clapsone was reduced to 25mg; however, no new reddish, pruritic papules have appeared. (Kor J Dermatol 1995;33 (2): 390-395)

      • 수중음향을 활용한 해저지진 탐지 가능성 연구

        고명권(Ko, Myungkwon),양원준(Yang, Wonjun),신성원(Shin, Sungwon),최지웅(Choi, Jee Woong) 한국연안방재학회 2018 한국연안방재학회 학술발표대회 논문집 Vol.2018 No.1

        해저지진은 지진에 의한 직접 피해와 지진해일 발생에 원인이 되기 때문에 해저지진 탐지연구는 매우 중요하다. 최근 연구에 따르면 해저에서 발생하는 지진은 육상 지진계를 이용한 탐지보다 수중에 위치한 수중청음기를 활용한 탐지 방법이 더욱 효과적이라는 연구 결과가 있다. 이에 본 연구에서 수중음향을 활용한 해저지진 탐지 가능성을 수치모델을 통해 확인하였다.

        심덕택(Duck Taik Shim),김영근(Young Keun Kim),이종석(Jong Suk Lee),고명권(Myoung Kwon Ko) 대한피부과학회 1994 대한피부과학회지 Vol.32 No.4

        Nevus lipomatosus cutaneous superficialis(NLCS) is a rare nevoiri anomaly characterized by ectopic adipose tissue in the dermis without predilection. In this disease two clinical types are distinguished: The classic type consists of asymptomatic linear or zosteriform coliection of soft, flesh colored to yellowish, papules or nodules that often coalesce into plaque. It is usually located in the pelvic girdle and lumbar area but has been repeted on the abdomen, thorax, thigh, and scalp. The solitary form usually appears later in life and can occur at any site. There is no sexurl irredilection or hereditary trend. There are no assoeiated abnor malities. The authors experienced three cases of typical NLCS including thia silitary type that had several solitary nodules irregularly. The first case was a 24-year-old female which has had multiple, flesh to dark brown-colored, confluent nodules over the left upper thigh for 5-year.. The second case is the solitary type that a 56-year-old female has had discrete bean sized to what sized nodules on the right buttock for 13-years. The third case was a 23-year-old female who had soft, yellowish skin colored, cerebriform tumor on the right buttock for 10-yesrs. Diagnos was confirmed by clinical and histopathologic findings.

        Idiopathic nodular panniculitis is an inflammatory disease of subcutaneous fat tissue which is clinically characterized by recurrent crops of nodular panniculitis. Some cases are accompanied by systemic features such as fever, malaise, abdominal pain and arthritis. We report a case of idiopathic nodular panniculitis in 36 year-old woman, who had erythematous subcutaneous nodules on the extremities, trunk and face accompanied by various general symptoms such as fever, malaise, abdominal pain and weight loss.
