This study was conducted by using the ICP-AES (Inductively Coupled Plasma - Atomic Emission Spectrometry) to investigate the seasonal changes of copper and manganese content in the raw bovine milk. From July 2003 to June 2004, the milk samples were collected from the two geographical locations, Chungcheong-do and Jeolla-do, in Korean peninsula. Copper (Cu) content was determined in the range of min. 10.10 to max. 21.00 ${\mu}g$/100 mL (13.79 ${\mu}g$/100 mL) in spring, 5.06 to 15.41 (10.17) in summer, 5.04 to 19.70 (10.70) in autumn and 6.96 to 17.90 (12.11) in winter. For manganese (Mn), 3.00 to 8.30 (4.87) in spring, 2.30 to 6.44 (3.75) in summer, 2.81 to 6.04 (3.82) in autumn and 2.25 to 9.02 (4.48) in winter. Those data have shown that levels of copper and manganese was relatively constant but higher in Spring than other seasons, suggesting that the levels were not affected by seasons and different locations in Korea.

지난해 수도권에서 월드컵경기가 진행되었던 2002년 6월 6일에 구리 수택동 지점에서 203ppb에 이르는 고농도 오존이 발생하였다. 이때의 기상상태는 바람이 약하고 일사량이 강하고 운량이 적는 둥 고농도 오존의 좋은 조건이었다. 반면 2002년 7월 27일은 6월의 경우와 마찬가지로 기상조건은 고농도 오존생성의 호조건이었으나 수도권 67개 지점의 오존 평균 농도가 30ppb이하의 낮은 농도를 나타내었다. 본 연구에서는 광화학모델인 Models-3/CMAQ을 이용하여 이러한 2가지 오존 사례를 모사하고 특징을 비교 고찰하고자 한다.

미 국방성에선 '94년 6월부터 PERRY 전 국방장관 지시에 의거 방위산업의 원가절감을 이유로 약 3만종의 군사규격중 30%에 해당하는 9천여종이 사용취소나 상용규격으로 바뀌는 대대적인 규격개혁 작업이 진행되었다. 이러한 변화는 미국과 군사규격체계를 공유하는 한국에도 직.간접으로 영향을 미칠것이라 판단되어, 변화를 인식하고 사전에 대비해야 할 필요성 때문에 이 글을 작성하게 되었다. 이 자료는 ‘94년 6월부터 '96년 6월까지 2년간 미 국방성에서 규격 개혁작업한 내용을 번역한 것으로 방위산업체와 규격관련 담당관의 검토가 필요하리라 판단된다.

BACKGROUND: To evaluate the impact of rapid temperature change at spring and the early summer seasons in climate change, we have investigated the physiological response and yield of onion in a greenhouse with thermostat control system. METHODS AND RESULTS: Seedlings of onion(cv. Sunshine) were planted on October 30, 2012 and harvested on May 30, 2013. The used treatments(March-April-May) for a rapid temperature change were T0(control): $6.0-10.4-17.2^{\circ}C$, T1: $6.0-5.4(-5)-17.2^{\circ}C$, T2: $6.0-10.4-22.2(+5)^{\circ}C$ and T3: $6.0-5.4(-5)-22.2(+5)^{\circ}C$. Total yields of bulb within the temperature change as high temperature treatment T2 and control treatment T0 were increased significantly(p<0.05), as compared to the low temperature treatment T1. Low temperature conditions significantly (p<0.05) reduced plant height, SPAD reading, crude protein and fiber etc., as compared to the TO and T2. CONCLUSION: The rapid temperature changes were highly affected by low temperature than high temperature. These results suggest that rapid climate change of future could need systematic standard model for physiological characteristics and yields of onion.

This experiment was conducted to determine best harvesting time and observe paeoniflorin and some chemical component concentrations of 4-year-old paeonia radix in Euisung and Milyang varieties. Concentrations of paeoniflorin and some chemical components were investigated at 8 periods from Feb. to Oct. Yield of paeonia radix was investigated in Aug. 19, Sep. 18 and Oct. 17. Paeoniflorin and some chemical components were changed seriously at May as flowering time and stabilized after June. The lowest dry matter ratio was 23% and the maximum shrinkage ratio was 47% in May during all the growing stages. Especially, the difference of paeoniflorin concentrations between Euisung and Milyang was about 2%, and paeoniflorin concentrations in Milyang were higher than in Euisung variety during all the stages. Serious infection of disease in October, stem length, stem number per stock and healthful stem ratio in October were more reduced than in August. Yield of paeonia radix was not different from August to September, but that of October harvest was obviously reduced by root-decay-disease. Reasonable harvesting time in 4-year-old paeonia radix was late August to mid-September. When infected shoot rate by disease were severely high, early harvest was more stable in the yield and quality aspects.

Maize double cropping with winter cereals is important for round-year production of forage or grain, and increase of self-sufficiency of upland grain crops such as maize and wheat. Changes of maize growth and yield for forage or grain according to late planting in June for double cropping with winter barely were investigated compared to proper planting in April for three years from 2007 to 2009. Forage and grain yields of maize planted in mid or late June decreased by 20~30% compared to proper planting in April, but total grain yields per year of double cropping increased by 30~40% compared to single cropped maize. Reduction of ear dry matter was less than that of stalk in late planting within maize plant part. Yield reduction by late planting was the least at Kwangpyeongok, which showed the highest grain yield, 850 kg $10a^{-1}$ in even though late planting in June. Meteorological condition during harvesting time of double cropped maize, which in late September (forage) and mid October (grain), were better than that of conventional maize harvesting time which in late August and mid September. It is thought that more researches for double cropped maize for higher grain production is needed in the future.

This study set out to investigate the changes to the growth, yield, and flavonoid contents of mungbean according to different seeding times from mid May to mid July in the southern region of Korea. Days to first flowering, days to first maturing, and cultivation period were shorter at later seeding time than earlier seeding time. But later the seeding time was, days from first maturing to first harvesting, days required between harvesting increased. Number of pods at first harvesting and yield of mungbean were highest when seeded at late June, showing increase in yield 14% more than at early June as standard seeding time. However number of seeds per pod and 1,000-seed weight at first harvesting were highest when seeded at mid July. The number of harvesting was smallest at two times when seeded at June or mid July. The contents of average vitexin and isovitexin in mungbean were highest in the order of mid July, late June, and mid May. In particular, their contents reached its highest point in the seeds of the second harvest. Considering the results of the cultivation period, yield, harvesting times, vitexin and isovitexin contents, the proper seeding time of mungbeans in the southern region of Korea will be from late June to mid July.
