최근 저자들은 스테로이드에 잘 반응하나 재발을 잘하고 천명음이 동반된 BOOP 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Cultivation of competent manpower is recognized as one of the important factors in the development of fisheries as well as of other industries. For reference to the development of education of fisheries high schools in the Republic of Korea, the author carried out a study on the education in Japan. The reason is why the education on fisheries had been initiated in Japan and her educational system has played the role of a model for neighboring countries. Even though the education on fisheries tends to shrink a little in recent years by diffusing the unwilling tendency to engage in 3D (dirty, difficult and dangerous) jobs, there are fifty-one high schools educating fisheries in Japan. Thirty-eight of them are specialized fisheries high schools and the others are comprehensive high schools to put common course and fisheries course together. In the first step of study, the goal of education on fisheries, organization of department and arrangement of curriculum are analysed. 1. In the newly arranged curriculum which will come into effect from 1994, the goal of education on fisheries is set up as "By educating fundamental knowledge and technology on the production and circulation in the field of fisheries, have students understand the significance and role of fisheries, and so cultivate ability and active attitude to the development of fisheries". The goal means that the circulation of fishery products are regarded as important as the production itself, and active attitude to the development of fisheries is also stressed, different from the present goal. 2. Standard departments directed by the Government are set up as five-Departments of Marine Fishing, of Fisheries Engineering, of Information Communication, of Fish Culture, of Sea Foods. But they are actually organized and named by the founders of schools-local government. Then there are many unique-named departments and the management of schools are somewhat flexible according to the situation of local district. 3. Special subjects are revised to twenty-four in the new curriculum from twenty-two in the present curriculum. Among them the contents are widely revised in the subjects such as Introduction to Fisheries, Fisheries Engineering, Communication Engineering, Communication Technology, Fish Culture. On the other hand, five subjects such as Information Treatment on Fisheries, Information Technology on Fisheries, Subjective Study, Fisheries Economics, Circulation of Sea Foods are newly set up to meet the changing phase of the time.

본 연구는 "광안콩"의 20일 묘를 공시하여 $0{\sim}90\;mM$의 염분조건에서 콩의 생리학적 피해정도를 산정하고 내염성 품종선발과 육종계획에 요구되는 기초자료로 활용하고자 수행되었다. 엽록소의 함량은 정상적인 관수를 실시한 대조구에 비해 염분 처리에서 $15{\sim}60%$ 감소하였고 농도증가에 따라 감소정도가 크게 나타났다. 염분 처리에 따른 광합성과 호흡량은 각각 $28{\sim}48%$와 $16{\sim}34%$ 감소하였고 $O_2$ 생산 비율보다 $O_2$ 소모 비율이 높게 나타났다. 수분 potential은 정상 잎(-1.5 MPa)에 비해 염분처리에서는 농도별로 -2.13에서 -2.69 MPa로 직선적으로 감소하였다. 개화기 염처리에서 대조구 $13.3\;{\mu}g$의 약 $17{\sim}22%$로 감소한 $11.8{\sim}10.4\;{\mu}g$이었으며 증산저항은 $1.08{\sim}1.70\;S/m$로 증가하는 경향이었다. 콩 잎의 수분증산 저항에 미치는 염분의 영향은 잎 내부의 기층저항이 가장 심한 차이를 보였고 무처리에서 45.9 S/m인 반면 염분처리에서는 $53.5{\sim}56.6\;S/m$로 농도증가에 따라 증가하였으며 기공저항과 잎 경계면의 저항은 큰 차이를 보이지 않았다. 대부분의 무기물 함량은 뿌리보다 앞에서 축적량이 더 많게 나타났으나 $Na^+$만이 뿌리에 더 많이 축적되었고 N, P, $K^+$, $Ca^{2+}$ 및 $Mg^{2+}$는 무처리에 비해 오히려 그 축적량이 감소하였다. 염분처리에 따른 콩 잎의 유리 proline은 무처리($10.5\;{\mu}g$) 대비 $1.8{\sim}4.2$배 ($184{\sim}434\;{\mu}g$)로 염 농도가 증가함에 따라 축적량이 증가하는 경향이었다. Nitrate reductase의 활성은 염 농도가 증가함에 따라 증가하였으나 농도가 90 mM 염분 처리에서의 증가폭은 다소 둔화되는 경향이었다. 한편 peroxidase 활성 역시 염분농도가 증가함에 다라 증가하는 것으로 나타났다.

Background: The Korea Interstitial Lung Disease Study Group has made a new nationwide idiopathic pulmonary fibrosis (IPF) registry because the routine clinical practice has changed due to new guidelines and newly developed antifibrotic agents in the recent decade. The aim of this study was to describe recent clinical characteristics of Korean IPF patients. Methods: Both newly diagnosed and following IPF patients diagnosed after the previous registry in 2008 were enrolled. Survival analysis was only conducted for patients diagnosed with IPF after 2016 because antifibrotic agents started to be covered by medical insurance of Korea in October 2015. Results: A total of 2,139 patients were analyzed. Their mean age at diagnosis was 67.4±9.3 years. Of these patients, 76.1% were males, 71.0% were ever-smokers, 14.4% were asymptomatic at the time of diagnosis, and 56.9% were at gender-age-physiology stage I. Occupational toxic material exposure was reported in 534 patients. The mean forced vital capacity was 74.6% and the diffusing capacity for carbon monoxide was 63.6%. Treatment with pirfenidone was increased over time: 62.4% of IPF patients were treated with pirfenidone initially. And 79.2% of patients were treated with antifiboritics for more than three months during the course of the disease since 2016. Old age, acute exacerbation, treatment without antifibrotics, and exposure to wood and stone dust were associated with higher mortality. Conclusion: In the recent Korean IPF registry, the percentage of IPF patients treated with antifibrotics was increased compared to that in the previous IPF registry. Old age, acute exacerbation, treatment without antifibrotics, and exposure to wood and stone dust were associated with higher mortality.

연구배경 : 피부근염/다발성근염 환자의 폐침범에 대한 국내의 보고는 드물며, 이에 폐를 침범한 피부근염/다발성근염 환자의 임상상을 살펴보았다. 방 법 : 1989년부터 1999년까지 서울대병원을 내원한 피부근염/다발생근염 환자의 임상양상과 방사선검사를 포함한 검사소견을 후향적으로 분석하였다. 결 과 : 총 79명(피부근염/다발성근염 : 54/25명)의 환자 중 24명(33%)의 환자에서 폐침범이 있었다. 폐침범이 있는 환자군의 여성비(11:1)와 연령($50{\pm}13$세)이 높았다. 폐침범이 있는 환자에서 호흡곤란(79%)과 기침(67%)의 증상이 있었고, ESR이 $47{\pm}7\;mm/hr$, CK/LD가 $2169{\pm}820/577{\pm}61\;IU/L$로 증가하였다. Anti-Jo1 Ab는 30%에서 양성이었다(p-value : 0.03). 흉부 HRCT 상 망상 또는 간유리 음영(9%), 선상 음영 또는 중격 비후(50%), 반점상 경화(38%), 벌집낭(33%), 결절 음영(17%)으로 관찰되었다. 환자는 $30{\pm}28$개월 동안 추적관찰 되었고, 스테로이드 단독치료(46%)와 면역억제제 병행치료(50%)를 받았다. 경과 중 사망률은 폐침범이 있는 군(21%)에서 폐침범이 없는 군(10%)보다 높은 경향을 보였다.
