1. 1974年 3月에서 1975年 3月사이 每月 大湖日과 小湖日에 洛東江 勿禁 益山市 士水道 舊取水場源水의 鹽化이온, 칼슘, 마그네슘의 量을 每時間마다 測定하였다. 2. 1974 年 3月에서 1975年 1月사이의 鹽化이온 濃度는 5.12-39.4ppm에 平均같이 11.9 ppm, 總 硬凌는 27.8-70.8 ppm에 平均값이 49.5 ppm 였고, 1975年 2月 9日에서 3月 7日까지의 潮差가 큰 期間에는 鹽化이온濃度 10.8-876 ppm에 平均값이 89.8 ppm, 總硬度는 48.0-407 ppm에 平均값이 89.9 ppm 였다. 3. 季節的으로는 冬季에 濃度가 높고 潮差가 큰 2月과 3月初 사이가 가장 높다. 鹽化이온濃度 150ppm를 넘은 날이 모두 2月에 들어있다. 4. 總硬度 역시 鹽化이온濃度와 비슷한 變動을 한다. 水道法의 許容限界인 300ppm를 넘는날이 2月 9日에서 3月 7日 사이에 約 4 日 程度 나타난다. 5. 水位는 河川水量과 潮位로써 정해지는 까닭에 水位만으로는 鹽化이온 濃度를 알수가 어렵지만 鹽化이온濃度와 水位의 時間的 變動關係는 水位가 높을 때 濃度가 높으며, 2月 및 3月에서 더욱 그러하다. 6. 潮位와 水位와는 약간의 時差를 두고 거의 같은 모양의 變動을 하며 最高湖位에서 最高水位까지 大潮日에는 約 2時間 30分, 小潮日에는 約 3時間의 差가 나타난다. The contents of chloride ion, calcium and magnesium in Nagdong River water were determined at Mul Geum where the intake station for Busan city water is located. Samples were taken in spring and neap tides of every month from March 1974 to March 1975. The range and mean values of the chloride ion and total hardness were 5.12-39.4ppm, 11.9ppm; 27.8-70.8ppm, 49.5ppm respectively from March 1974 to January 1975. The highest values were found in the period of the widest tidal range of a year, from February 9 to March 9 in 1975, such as the ranges and means of chloride ion and total hardness were 10.8-876 ppm, 89.8ppm; 48.0-407ppm; 89.9ppm. On several days of this period those concentrations were over the criteria of drinking water, 150 ppm in chloride and 300ppm in total hardness. Chloride ion concentration was increased with increasing of water level of the Nagdong River at Mul Geum. The patterns of the variations of tide level were similar to that of water level with delay of 2. 5 hours in spring tides and 3 hours in neap tides.

Heavy metal concentrations have been determined in fishes and shellfishes sampled from October 1971 to April 1972 in Korea. In general, fish viscera, shellfish muscle and crustacean exoskeleton contained high concentrations of the metals. With regard to the regional variations of the metals, samples of the west coast of Korea contained relatively high concentrations of mercury, copper, cadmium and lead, but those of the south coast contained high levels of cadmium and lead. In particular, the concentrations of copper in the samples of the west coast were almost twice as much those of the other coasts. The concentrations of mercury in the samples, as a whole, ranged from 0.02 to 0.58ppm with Boa an average of 0.16ppm. The concentrations of cadmium were higher in the fish viscera and shellfish than the fish muscle, ranging from less than 0.02 to 0.78ppm with an average of 0.12ppm in the fish and shellfish muscle samples. The lead concentrations were slightly high in the fish viscera. In the muscle and bone of fish and shellfish, the range was 0.06-4.84ppm with an average of about 1ppm. The concentrations of copper were very high in the viscera of fish and shellfish. The shellfish muscle contained almost four times as much copper as in the fish muscle, particularly cephalopods, i.e., squid and octopus, contained very high levels of copper, and oysters collected from Gunsan area on the west coast contained the highest levels of copper. The concentrations of copper ranged from 0.12 to 28.7ppm with an average of 1.4ppm in the fish muscle and of 5.9ppm in the shellfish muscle.

The annual variations of some heavy metal concentrations, Al, Mn, Fe, Cu, Pb, Zn, Cd, Hg were determined on tile day of spring tides in every month from May 1977 to April 1978 at eight stations in the Nagdong River downstream. Samples were taken at intervals of one or two hours from 7 a.m. to 7 p.m. at each station. Annual ranges and means of concentrations of the heavy metals are as follows : aluminium 40.7-3700 ppb, 286 ppb; manganese 10.3-261.5 ppb, 80.8 ppb; iron ND-1237 ppb, 147.7 ppb; copper ND-30.9 ppb, 2.49 ppb; lead ND-29.9 ppb, 1.10 ppb; zinc ND-156.8 ppb, 5.61 ppb; cadmium ND-1.22 ppb, 0.09 ppb; mercury ND-0.37 ppb, 0.02 ppb respectively. In general, the contents of heavy metals except managanese and mercury were higher at the stations above station one, Kupo, though the ranges of the contents showed remarkable difference according to the sampling stations. Annual means of the concentrations of iron and manganese were exceeded already the desirable standards for industrial water and closed to the criteria of raw water for public supply. The values that over the criteria of raw water were sometimes found. Mercury concentration showed comparative high level such as ND-0.37 ppb in annual range but it was not over the environment criterion, 0.5 ppb. Aluminium, iron and mercury showed generally high values in summer period and other metals in winter period, through the patterns of seasonal variations were difference depending on the sampling stations and the kind of metals.

A gamma camera system using a pinhole collimator is used to locate a large area such as that of a radiation disaster. However, the existing pinhole collimators have difficulty in determining the correct position because the rotation radius and the magnification are fixed. The purpose of this study was to use Monte Carlo simulations to optimize the pinhole collimator of a gamma camera with magnification images for radiation monitoring. The sensitivity and the resolution were simulated for various the hole diameters and channel heights. This allowed the optimal design variables for each magnification were optimized between 3.5 and 4.5 mm for magnifications from 1.0 to 3.0. The simulation results allowed us to determine the optimal values of the hole diameter and the channel height, which was be 4 mm and 4 mm, respectively. These results demonstrated that the pinhole collimator designed in this study can be utilized to create a disaster radiation-monitoring system. 방사선 재난 구역 등 넓은 영역의 위치를 파악하기 위해 바늘구멍 조준기를 사용한 감마카메라 시스템이사용되고 있다. 하지만 기존의 바늘구멍 조준기는 회전반경 및 확대율이 고정되어 정확한 위치를파악하는데 어려움이 있다. 이에 본 연구는 감마카메라 검출기를 이동하여 확대 영상을 얻을 수 있는시스템에 적용 가능한 바늘구멍 조준기의 설계변수를 도출하였다. 감마카메라 시스템의 모델링과 조준기성능평가를 위해 GATE을 이용하였다. 바늘구멍 조준기의 구멍직경 및 채널높이를 다양하게 변경하여민감도와 공간분해능의 결과값을 바탕으로 조준기의 설계변수 값을 도출하였다. 그 결과 각 배율에최적화된 설계 변수는 방사선원 위치의 공간분해능의 최소 하한을 제한하여 1.0 배율에서 3.0 배율까지구멍 직경 3.5 – 4.5 mm 사이에서 최적화 변수를 도출 하였다. 본 연구를 통해 최적화된 조준기의 설계변수 값을 바탕으로 방사선 재난 감시에 활용하는 등 모니터링 상황에 맞게 사용할 수 있음을 검증하였다.

원종훈,박상준,주영중,임종주,박상권 한국공업화학회 2002 한국공업화학회 연구논문 초록집 Vol.2002 No.0

Recently, several studies have been performed for the substitution of the conventional short chain alcohol by butyl lactate as a cosurfactant on the preparation of microemulsions. The effort is attractive since butyl lactate can be obtained from renewable resources and may be used as a safe and biodegradable product in the cosmetic and the dermal drug delivery. In the present work, the phase behavior was investigated and the characterization study was performed for the SDS microemulsion system which employed butyl lactate as a cosurfactant. The butyl lactate system provided the wider microemulsion region than the system for pentanol. The results of conductivity study indicated that the ratio, r = [cosurfcatant]/[SDS] at the interface, was varied from 1 to 2 depending on the composition of microemulsions and the results revealed that the area occupied by butyl lactate at the W/O interface was about 33 A2..
