본 연구는 제주지역에서 소비되는 식품중의 ^(137)Cs과 ^(40)K 방사능 농도를 조사하여, 식 품 섭취에 따른 ^(137)Cs와^(40)K에 의한 내부피폭 선량의 값을 평가함으로써 만일의 원자 력 사고로 인한 방사능 오염에 대처할 수 있는 기초 자료를 확보하고자 수행하였다. 시료로 채위한 식품류는 농산물 31, 축산물 6, 수산물 12, 임산물 4, 그리고 가공식품(차류)이 3종류 였고 방사능 분석은 고순도 게르마늄검출기가 장착된 감마선분광게로 수행하였다. 시료중 ^(137)Cs방사능 농도범위는 농산물이 MDA이하∼ 650 mBq/㎏·fresh, 축산물 MDA이하 ∼131 mBq/㎏·fresh, 임산물 MDA 이하 ∼834 mBq/㎏·fresh,, 수산물 MDA이 하∼ 253 mBq/㎏·fresh, 그리고 가공식품은 320∼483 mBq/㎏·fresh 이었다. ^(40)K의 경 우는 농산물 16.6∼542 Bq/㎏·fresh,, 축산물 39.1∼294 Bq/㎏·fresh, 임산물 85.5∼116 Bq/ ㎏·fresh, 수산물 50.1∼657 Bq/㎏·fresh, 그리고 가공식품 33.6∼1,065 Bq/㎏·fresh, 범위 였다. 시료증 ^(137)Cs 방사능 농도가 가장 높은 것은 표고버섯으로 834 mBq/㎏·fresh 이 었으며, ^(40)K은 커피가 1,065 Bq/㎏·fresh 가장 높았다. 각 식품류 중 ^(137)Cs와 ^(40)K에 의한 연간 유효선량은 농산물이 66,543 nSv로 가장 높았 고, 축산물 19,311, 가공식품(차류) 6,648, 수산물 6,579 그리고 임산물 860 nSv 순으로 낮았 으며 이것을 모두 합한 총 연간 유효선량 값은 99,941 nSv 이었다. 본 연구에 포함된 식품 의 1인당 연간 섭취량이 연간 총 식품 섭취량의 60%임을 감안해도 자연환경 중에서 이루어 지는 외부피폭에 의한 연간 유효선량인 2,400,000 nSv에 비하면 무시할 정도여서 평상시 식 품섭취에 의한 방사선 내부피폭은 매우 미량이었다. 이상의 자료는 유사시 방사선에 의한 식품류 오염정도를 식별하는데 필수불가결할 것으로 사료된다. This work was conducted to provide the reference data of radioactivity in the foodstuffs at a radiological emergency situation in Jeju Island. The sampled foodstuffs were agricultural (31), livestock (6), marine (12) and forest products (4), and processed foods (3) consumed by Jeju Islanders. ^(137)Cs and activities were determined by HPGe Y-ray spectrometry. The activity ranges of ^(137)Cs was <MDA (less than minimum detectable activity-650 mBq/㎏ ·fresh in the agricultural products, <MDA-131 mBq/㎏·fresh in the livestock, <MDA-834 mBq/㎏·fresh in the forest, <MDA-253 mBq/㎏·fresh in the mafine and 32.0-483 mBq/㎏·fresh in the processed foods (tea). In case of ^(40)K, the activity was 166-542 Bq/㎏·fresh in the agricultural products, 39.1-294 Bq㎏· fresh in the livestock, 85.5-116 Bq/㎏·fresh in the forest, 50.1-6.57 Bq/㎏·fresh in the marine, and 33.6-1,065 Bq/㎏·fresh in the processed foods (tea). The highest activity of ^(137)Cs, 834 mBq/㎏·fresh was observed in oak mushroom and ^(40)K, 1,065 Bq/㎏·fresh in coffee. Annual effective doses of ^(137)Cs and ^(40)K by intake of foodstuffs per capita were the following order; agricultural products (66,543 nSv) > livestock products (19,311 nSv) > processed foods (6,648 nSv) > marine products (6,579 nSv) > forest products (860 nSv). Therefore, total annual effective dose was summed 99,941 nSv which is quite low level comparing to the annual effective dose by external exposure, 2,400,000 nSv. The data obtained in this study can be useful for monitoring whether the foodstuffs are contaminated or not at an emergency radiation accident, and showed that the foodstuffs consumed in Jeju are safe in terms of annual effective dose of ^(137)Cs and ^(40)K.

The effects of various sugars and amino acids of the stability of the plam oil in Ramyon, was studied. Stability of the palm oil in Ramyon was determined from acid, peroxide, anisidine values and color development. The effects of sugars added on the stability of the palm oil in Ramyon was in order of arabinose, xylose, glucose, fructose, lactose, sucrose, raffinose. In addition of amino acids and glucose, the stability of the palm oil in Ramyon showed a significant increase in order of β-alanine, glycine, valine, lysine, but threonine and glutamic acid showed less stability. The effects of glycine concentration on the stability was increased to 0.5%. After deep-fried, color developments of Ramy on surface increased in darkness to 0.5% glycine concentration and decreased during the storage period.

The parasitic copepod. Caligus chanos parasitized on labridae fish around MunSum. Cheju Island, have been basically studied form Sep.. 1996 to Aug.. 1997. Parasitic pattern and water temperatures have a close relationship. which is high in June and low form Feb. to Apr.. Fishes of main hosts were Pseudolabrus japonicus and Pteragogus Ragellifer. Parasitic copepods prefer the body and tail of the host to the head, and prefer adult host to juveniles or older one.

Rice breeding strategy for Africa through KAFACI program in Korea

Kang Kyung-Ho,Bo-Kyeong Kim,Jae-ki Chang,Kyung-Rae Cho,Geun-Pyo Lee,Sang-bok Lee,Ji-Ung Jeung 한국육종학회 2014 한국육종학회 심포지엄 Vol.2014 No.07

In Africa, rice is the fastest demanding staple food with a high growth rate of consumption at 4.5% per annum. Currently Africa occupies 32% of world rice imports, and pressure on rice is expected to rise in the near future. Faced with this deficit, Korea has launched the rice breeding project through Korea-Africa Food & Agriculture Cooperation Initiative (KAFACI) of which goal is to increase rice productivity through accelerated development of improved germplasm and varieties in Africa. As of 2013, the ten African member countries joined the rice breeding projects of KAFACI program; they are Cameroon, DR Congo, Ghana, Kenya, Malawi, Mali, Nigeria, Sudan, Tanzania, and Uganda. We adopted the breeding strategy of intervarietal cross and anther culture to speed up high-yielding secondary populations using the Korean and African germplasm. Korean germplasm is composed of 1) temperate japonicas adaptable to tropical conditions of short-day length and high temperature 2) wide-cross derivatives from African wild species, O.glaberrima and O,longistaminata, and 3) tongil-type varieties. These germplasm is evaluated for adaptability in Africa and African partners make crosses with local germplasm with the best selections. Korea produce double-haploid populations from these crosses for another cycle of selection for high-yielding lines in Africa. Inter-varietal crosses and double-haploid technology could accelerate the development of high-yielding germplasm and new rice varieties in Africa within short project period.

Case Reports : Renal infarction resulting from traumatic renal artery dissection

Kyung Pyo Kang,Sik Lee,Won Kim,Gong Yong Jin,Ki Ryang Na,Il Yong Yun,Sung Kwang Park 대한내과학회 2008 The Korean Journal of Internal Medicine Vol.23 No.2

Renal artery dissection may be caused by iatrogenic injury, trauma, underlying arterial diseases such as fibromuscular disease, atherosclerotic disease, or connective tissue disease. Radiological imaging may be helpful in detecting renal artery pathology, such as renal artery dissection. For patients with acute, isolated renal artery dissection, surgical treatment, endovascular management, or medical treatment have been considered effective measures to preserve renal function. We report a case of renal infarction that came about as a consequence of renal artery dissection.
