문홍식,오창영,Moon Hong-Sik,Oh Chang-Young Korean Veterinary Medical Association 1978 대한수의사회지 Vol.14 No.4
1973년 6월부터 1975년 6월까지 2년간 창경원 동물원에서 사유중에 사망한 동물과 조류의 폐와 수집된 비둘기의 폐 231건을 대상으로 하여 육안적 및 조직학적으로 폐내 분근침착상태를 조사한 결과 다음과 같은 결론을 얻었다. 1. 총231건의 동물폐중 170건($73.6{\%}$)이 탄폐로 검출되었으며 이중 고도침착이 $3.9{\%}$로서 대개가 경도 및 중등도 탄폐로 검출되었다. 2. 포유류에선 $89.3{\%}$ 조류에선 $71.5{\%}$가 탄폐로 나타났으며 파충류에서는 3건 모두 양성이었다. 이중 고도탄폐는 포유류와 조류에서 각각 $3.6{\%}$ 및 $4.5{\%}$였다. 3. 사유기간이 길수록 탄폐는 심한 경향이 있었다. 즉 사유기간이 1년 이하의 동물은 $53.8{\%}$ 2년 이상에서는 $87.2{\%}$가 양성으로 나타났다. 4. 축사내사유가 축사외사유은 각각 $68.6{\%}$와 $74.5{\%}$의 탄폐가 있어 유의한 차가 없었다. 5. 육안적소견으로 탄내 분허침착을 확인한 경우는 5건밖에 없었으며 전부 조직학적검사로서 확인되었다.

키랄 보조제로서의 C<sub>2</sub>-대칭성 피롤리딘 아미드의 합성과 광학 순도 결정
문홍식,고동수,Moon, Hong-sik,Koh, Dongsoo 한국공업화학회 1998 공업화학 Vol.9 No.6
쉽게 얻을 수 있는 1,2:5,6-di-O-isopropylidene-D-mannitol (1)로부터 $C_2$-대칭성 피롤리딘 아미드 (8)을 합성하였다. 벤질 아민과 dimesylated hexitol (4)를 고리화 반응 시키면 트랜스 형태의 $C_2$-대칭성 피롤리딘 아민(5)가 주생성물로 얻어지나, 이와 함께 이성질화가 일어나 시스 이성질체인 화합물(6)도 생성된다. 피롤리딘 아민 (5,6)을 탈보호된 아민 (7)을 거쳐 아미드 (8,9)로 변형시켜 이를 순수한 형태로 분리하고, 이 $C_2$-대칭성 피롤리딘 아미드(8)의 광학 순도를 측정하기 위해 Mosher 유도체(13,14)를 합성하였다.$^1H$ 과$^{19}F$ NMR 실험으로 Mosher 유도체 (13,14)가 단일 물질임이 밝혀졌고, 이로서 피롤리딘 아미드 (8)이 광학적으로 순수한 화합물임을 확인하였다. Optically pure $C_2-Symmetric$ pyrrolidine amides (8) were synthesized from readily available 1,2:5,6-di-O-isopropylidene-D-mannitol (1). Cyclization of dimesylated hexitol (4) with benzyl amine gave an inseparable mixture of $C_2-Symmetric$ pyrrolidine amine derivative (5) as a major product, concurring with its cis isomer (6) as a minor product. The pyrrolidine amines (5,6) were converted to separable pyrrolidine amides (8,9) via free amine (7). Optical purity of desired $C_2-Symmetric$ pyrrolidine amide (8a) was determined with its Mosher derivatives (13,14) by their $^1H$ and $^{19}F$ NMR spectra.

An investigation on the heavy metals in the lung of 82 capture pigeons and 184 collected dogs from Seoul, Incheon and Yeongju district was carried out from 1974 to 1976. The results were as follows: 1. The highest concentration of heavy metals in the pigeon lungs was 1791.3㎍/g of iron while the lowest was 0.16㎍/g of chromium. The concentration of heavy metals of the lungs increases iron, copper, magnesium, zinc, cadmium, nickel and cobalt in that the pneumonoconiosis. 2. Both the highest and lowest concentration of heavy metals in the dog lungs were shown as 1625.8㎍/g of calcium in the pneumonoconiosis of minimum degree at Seoul. 3. The highest concentration of iron in the dog lungs was 1081.1㎍/g in the pneumonoconiosis of slight degree at Seoul while the lowest was 4612.8㎍/g of calcium in the pneumonoconiosis of minimum degree at Seoul. 4. The concentration of copper for the samples collected at Yeoungju was found to be highest of 9.05㎍/g while the lowest was 5.00㎍/g at Incheon. 5. The highest concentration of magnesium in the dog lungs was 452.8㎍/g at Yeongju while the lowest was 242.2㎍/g at Incheon. 6. Both the highest and lowest of zinc in the dog lungs were shown as 106.8㎍/g and 64.9㎍/g in the pneumonoconiosis of minimum and moderate degree at Seoul. 7. The highest concentration of cadmium in the dog lungs was 0.83㎍/g at Yeongju while the lowest was 0.10㎍/g in the pneumonoconiosis of moderate degree at Seoul. 8. The highest concentration of nickel in the dog lungs was 1.39㎍/g at Incheon while the lowest was 0.64㎍/g in the pneumonoconiosis of moderate degree at Seoul. 9. The highest concentration of cobalt in the dog lungs was 0.40㎍/g in the pneumonoconiosis of moderate degree at Seoul while the lowest was 0.13㎍/g at Yeongju. 10. The highest concentration of lead in the dog lungs was 1.45㎍/g in the pneumonoconisis of minimum degree at Seoul which the lowest was 0.47㎍/g at Yeongju. 11. The highest concentration of chromium in the dog lungs was 0.13㎍/g at Incheon while the lowest 0.05㎍/g at the pneumonoconiosis of minimum degree at Seoul. 12. Both the highest and lowest of calcium in the dog lungs were shown as 1625.8㎍/g and 921.2㎍/g in the pneumonoconiosis of minimum and moderate degree at Seoul. 13. The concentration of tin thallium and beryllium were detected with trace amounts.

자기자화자왜센서를 이용한 설비 off-line Health Monitoring 시스템 개발
김이곤(Yi-Gon Kim),문홍식(Hong-Sik Moon),김준(Jun Kim),김지현(Ji-Hyeon Kim) 한국지능시스템학회 2012 한국지능시스템학회논문지 Vol.22 No.4
본 논문은 석유화학 플랜트 등의 결함을 자기자왜센서기술을 활용하여 주기적으로 검사하는 오프라인 모니터링이 가능한 ‘Health Monitoring System’의 개발과 그 활용성에 대해 확인하였다. 기존의 유도파 검사 방식은 용접부위 검사에는 적용할 수 없고, 일반적인 부위에서도 노이즈 및 반사파 등으로 검사의 정밀도에 한계를 갖고 있다. 본 기술은 주기적인 모니터링을 통해 결함의 진전에 따른 변위정보를 활용할 수 있음으로서, 더 정밀한 검사가 가능하기 때문에 석유화학 플랜트에서 매우 유용하게 활용될 수 있을 것으로 사료된다. This thesis examines the development and application of ‘Health Monitoring System’ which monitors periodically the state of a pipe of petrochemical plant by using magnetostrictive sensor technology. The existing guided-wave inspection methods cannot be applied to welding part inspection in pipe, and has a limit of precision when applied to general parts because of noise, reflected waves, and so on. This technology uses the information on displacement of a defect through periodic monitoring, which makes more precise inspection, and can be utilized very usefully in a petrochemical plant.
