쏨뱅이목 날개줄고기과에 속하는 Aspidophoroides monopterygius 6개체 (표준체장 151.4~171.2 mm) 가 강원도 삼척과 강릉 연안에서 동해구외끌이중형저인망에 의해 채집되었다. 본 종은 긴 체형, 1개의 등지느러미, 입이 몸의 전방에 위치, 두부에 수염이 없으며 주둥이에 몸의 후방을 향하는 날카로운 비골극이 있는 것이 특징이다. 본 종은 민어치(Anoplagonus occidentalis)와 형태적으로 매우 유사하지만, 비골극을 가지는 점에서 차이가 있다. 우리나라에서 처음 보고되는 본 종의 국명으로 “악어줄고기”를 제안한다. Six specimens (151.4~~171.2 mm in standard length) of the poacher Aspidophoroides monopterygius were collected by Danish seine net in the coastal waters off Samcheok and Gangneung, the East Sea, Korea. This species is characterized by a slender body, one dorsal fin, terminal mouth, no barbel on the head, and a pair of nasal spines on the snout. It differs from Anoplagonus occidentalis Lindberg in having a nasal spine. We describe it as the first record within the Korean fish fauna, and propose the new Korean name “Ak-eo-jul-go-gi” for this species.

차세대 군용⋅소방용⋅산업용 화학보호복 개발

박평규(Pyoung Kyu Park),윤병선(Byoung Sun Yoon) 한국화재소방학회 2022 한국화재소방학회 학술대회 논문집 Vol.2022 No.춘계

화학보호복은 크게 군용⋅소방용⋅산업용으로 분류되고 있다. 먼저, 군용 화학보호복은 침투성(Permeable)과 불침투성(Impermeable) 보호복으로 나뉘며 주요 역할은 전쟁 작용제(Chemical weapon agents)인 신경/혈액/수포/질식 등을 보호하기 위한 것이 가장 중요하며 최근에는 산업분야에 화학사고들이 많기 때문에 TICs(Toxic Industry Chemicals)의 필요성이 대두되고 있다. 국내의 화학사고의 현황(2014.1.8. ~ 2021.11.21.)을 보면 첫 번째가 누출(535건), 다음은 화재(42건), 폭발(55건), 및 기타(40건)가 전국적으로 발생되었으며 특히, 경기도가 가장 많은 분포를 보였고 다음으로 울산, 충남 및 전남 순으로 나타났다. 소방용 화학보호복은 크게 3종류(Leve A, Level B, Level C)로 나뉘며 Level A화학보호복은 내화학성 뿐만 아니라, 난연성과 열방호성이 있어 화재현장에 사용가능한 보호이며 Level B는 비난연성 보호복인 반면 Level C보호복은 Level A와 Level B를 제외한 보호복이다. 반면 산업용 화학보호복은 유럽규격을 그대로 인용하여 Type 1 ~ Type 6까지 있다. 최근 선진국인 미국 Dupont의 Tychem 6000 FR(이전, ThermoPro)과 독일 Drager사의 CPS 7900은 제품 무게를 5.8kg로 경량화하여 기존 제품보다 착용 편리성과 피로도를 향상시켰다. 특히, Tychem 6000FR은 원단 중량이 280g/m2로 매우 경량화된 제품이며 원단에 화학물질을 방호할 수 있는 다층복합필름이 없는 것이 특징이며 열가소성 플라스틱이 다층으로 코팅되어 있으므로 내화학성능, 난연성능(ISO 13506) 및 전기아크에 대한 성능을 보유하고 있어 차세대 화학보호복으로 고려되고 있다. 반면, 국내 화학보호복은 열방호성능, 난연성능 및 내화학성능을 우수하나 약 10kg의 무게로 소방공무원의 피로도(Stress)를 상승시키는 결과를 초래하여 실수요자인 소방관들이 이에 대한 개선 의견이 많아 혁신적인 원단개발이 필요한 실정이다. 본 연구에서는 국내외 가장 높은 수준의 화학보호복의 특성을 비교하며 향후 개선되어야 할 사항 등을 논의하고자 한다.

울산사고현장의 소방용 특수방화복의 요구사항 및 향후 개선방안에 대한 연구

박평규(Pyoung Kyu Park),윤병선(Byoung Sun Yoon) 한국화재소방학회 2022 한국화재소방학회 학술대회 논문집 Vol.2022 No.춘계

지난 2021년 울산화재(화재진압 중 20대 소방관(노명래 소방사) 및 2022년 평택 냉동창고화재(소방관 3명)로 부터 순직하는 사고로 인하여 소방청 등 및 국민들도 많은 충격을 주었다. 당시 5명의 소방관이 3층 미용실내부로 투입되었지만 가연성물질인 다량의 스프레이가 폭발하므로 인하여 전실화재(Flashover)를 일어나서 1층에 에어메트도 있어지만 너무 강력한 화염에 맞섰우 없었기 때문에 5명 소방관의 등쪽에 2도 및 3도 화상을 입은 것으로 판단된다. 특히, 문헌상 Flashover는 최소 500℃부터 시작하여 최대 1100℃까지 이르며 발화기, 성장기(Pre-flashover), 최성기 및 감쇠기에 단계별 나아간다. 이 상황에서는 산소는 완전 고갈상태이며 일산화탄소는 10% ~ 20% 및 이산화탄소는 20% 이상을 모니터링되고 있다. Flashover상태에서는 모든 소방관은 사망상태로 보는 경향이 많다. 특히, 소방관의 제 2의 피부인 특수 방화복(Turnout gear)은 소방관의 개인보호장구류중 가장 많은 부피를 차지하고 있다. 최근에 친환경 전기차가 많이 보급되고 있으며 수소차 및 관련 시설들에 대한 연구가 활발히 수행중이다. 수소가스는 화학가스중에 공기보다 가볍워 쉽게 휘발되는 특성이 있으나 폭발충격이 매우 크다고 볼 수 있다. 2019. 6. 10 노르웨이의 오슬로인근에 샌드비카의 수소충전소에서 폭발사고가 일어났으며 폭발의 충격으로 충전소 주변에 세워진 차량들의 유리창이 깨지고 에어백이 터져 2명 이상이 부상되는 피해 발생되었다. 앞으로 많이 발생될 수 있는 대형화재에 대응하기 위한 1차 대응자(First responder)인 소방관 위한 현재와 미래의 보호복에 관한 연구를 하고자하며 특히 열적인 성능위주로서 현용 방화복과 해외 방화복의 2도 및 3도 화상정도를 비교하므로 써 극한 화염인, 전실화재에 대응 가능한 수준 정도를 파악하고자 한다

This study was performed to estimate biomass and provide management guidance through population ecological characteristics, including growth parameters, instantaneous coefficients of natural and fishing mortalities, and age at first capture of the starry flounder, Platichthys stellatus and olive flounder, Paralichthys olivaceus of Korea. For describing growth of this species, a von Bertalanffy growth model was adopted. The von Bertalanffy growth parameters estimated from a non-linear regression for starry flounder were L∞=48.25 cm, K=0.16/yr, and t0=-1.48, respectively and those for olive flounder were L∞=86.46 cm, K=0.26/yr, and t0=-0.29, respectively. Biomass of Platichthys stellatus was estimated by direct biomass estimation method was 2.6 M/T, that was estimated by indirect method was 13.4 M/Tt. Those of Paralichthys olivaceus were estimated as 10.1 M/T, 19.3 M/T, respectively. An yield per recruit analysis showed that the current yield per recruit on Platichthys stellatus was about 48.2 g with F=0.646/yr and the age at first capture (tc) 1.35yr, that on Paralichthys olivaceus was about 167.6 g with F=1.121/yr and the age at first capture (tc) 1yr.
