본 연구에서는 건지황을 증숙하여 제조하는 숙지황 제조과정 동안의 중금속과 농약의 안전성을 평가하였다. 숙지황을 제조할 때 건지황을 황주로 9번 증숙하는 과정동안 증숙한 한국 시료의 평균은 As는 $0.147{\pm}0.007\;mg/L$이었으며, Cd는 $0.025{\pm}0.001\;mg/L$이었고, Pb는 $0.193{\pm}0.021\;mg/L$이었다. 또한 중국 시료의 평균은 As, Cd와 Pb가 각각 $0.0145{\pm}0.014\;mg/L,\;0.023{\pm}0.002\;mg/L$와 $0.299{\pm}0.013\;mg/L$이었다. 건지황을 숙지황을 제조하는 동안 중금속의 농도는 큰 변화가 없었다. 일반 시중 숙지황 중에서 As는 우리나라 시료는 평균 $0.106{\pm}0.052\;mg/L$이었으므로 As의 허용기준 3.0mg/kg에 3.53%이었으며, 중국 시료는 $0.135{\pm}0.011\;mg/L$이었으므로 As의 허용기준에 4.50%이었다. 우리나라와 중국의 숙지황 중 Cd농도는 허용기준 0.3 mg/kg에 각각 6.66%와 5.33%였다. Pb의 허용기준은 5.0 mg/kg인데 우리나라와 중국의 숙지황 중 Pb농도는 허용기준의 5.16%와 7.86%였다. 이와 같이 우리나라와 중국의 숙지황 중 중금속의 농도가 허용기준의 $3{\sim}8%$ 수준으로 매우 낮았으며, 이는 중금속으로부터 안전하였다. 우리나라 안동과 중국 하남의 건지황 중 잔류농약으로 Aldrin, $BHC-{\alpha},\;BHC-{\beta},\;BHC-{\gamma},\;BHC-{\delta}$, Captan, Chlorfenapyr, Chlorpyrifos, DDD, DDE, DDT-o,p, DDT-p,p, Dieldrin, Endosulfan-sulfate, $Endosulfan-{\alpha},\;Endosulfan-{\beta}$, Fenitrothion, Penthoate, Permethrin, Quintozene, Tolyfluanid와 Vinclozolin 등이 검출되지 않았다. 숙지황 제조에 사용된 황주 시료에도 이들 농약이 모두 동일하게 불검출로 나타났다. 따라서 이를 이용하여 제조한 숙지황에도 이들 농약이 불검출 되었다. 따라서 본 연구에서 검토된 우리나라와 중국지역의 건지황으로 제조된 숙지황은 중금속과 잔류농약이 식품의약안전청 기준에 적합한 안전성이 확인되었다. To obtain the risk assessment of hazardous materials with maturing process of Rehmanniae Radix Preparata, the residual heavy metals and pesticides in samples are surveyed. Concentration of As, Cd and Pb during the maturing process of Rehmanniae Radix Preparata of Korea are $0.147{\pm}0.007\;mg/L,\;0.025{\pm}0.001\;mg/L\;and\;0.193{\pm}0.021\;mg/L$, respectively. Concentration of As, Cd and Pb during the maturing process of Rehmanniae Radix Preparat of China are $0.0145{\pm}0.014\;mg/L,\;0.023{\pm}0.002\;mg/L\;and\;0.299{\pm}0.013\;mg/L$, respectively. Concentration of As, Cd and Hg remain unchanged during the maturing process of Rehmanniae Radix Preparata. Concentration of As, Cd and Pb in Rehmanniae Radix Preparat on the Korea are 3.53%, 6.66% and 5.16% for Korea Food & Drug Administration (KFDA) advisory level, respectively. The residual pesticides, such as aldrin, $BHC-{\alpha},\;BHC-{\beta},\;BHC-{\gamma},\;BHC-{\delta}$, captan, chlorfenapyr, chlorpyrifos, DDD, DDE, DDT-o,p, DDT-p.p, dieldrin, endosulfan-sulfate, $endosulfan-{\alpha}$, $endosulfan-{\beta}$, fenitrothion, penthoate, permethrin, quintozene, tolyfluanid and vinclozolin, are not detected in Rehmanniae Radix Preparat on the Korea and China. The hazardous materials in Rehmanniae Radix Preparata on the Korea and China are verified the safety of the residual heavy metals and pesticides compare with Korea Food & Drug Administration (KFDA) advistory level.

문영수 한국환경과학회 1996 한국환경과학회지 Vol.5 No.3

This study is an attempt to classify climatic regions of Korea based on the data of sunshine duration and to clarify the characteristics of sunshine for each divided regions. The data used in this study are the mean values of monthly and ten-daily sunshine duration, sunshine percentage, solar radiation and cloud amount obtained from 63 weather stations of the Korea Meteorological Administration during the period of 1974∼1993. The characteristics of annual change of sunshine percentage, annual duration of sunshine, percentage of sunshine, annual radiation, amount of cloud, days of sunshine percentage above 80% and days of sunless are investigated by the mean values of the stations belong to divided regions. The ward method of hierarchical cluster analysis is adopted to the analysis of data for the regional division. The results obtained in this study are summarized as follows. (1) The sunshine regions of Korea can be divided into six regions of the central west, central east, south west, south east, Ullung-do and Cheju-do. These are strongly affected by the distribution of inclined slopes taking account of the topographic characteristics of Korea. (2) Annual distribution shows the sunshine duration of 1777∼2287 hours, sunshine percentage of 40∼53%, solar radiation of 3469∼4637 MJ/㎡, cloud amount of 5.0∼6.1, days of sunshine percentage above 80% of 53∼116days and sunless days of 46∼71days. (3) The types of annual change of sunshine percentages is classified with four types of minimum in July and maximum in October, minimum in July and maximum in December, high in May and October and low in July and January, high in May and November and low in June and January. (4) The Iong-term trend of sunshine duration decrease in peninsula area but increase in island area and the long-term inclination of cloud amount is almost zero. The author believe this tendency is related to a pollutional turbidity than a cloud amount in inland area.

This study is an attempt to investigate the chemical components of precipitation and its variation according to surface wind. Precipitation samples were collected by an wet-only precipitation sampler during the period of October 1994 to September 1995 at Kyungsan in Korea. The results obtained in this study are summerized as follows. The annual average of precipitation pH is 5.0, the highest month of pH is July of 5.5, and the lowest month of pH is December of 4.4. The most frequent appearance is in the range of pH 5.0 to 5.5 and its rate is 56.8%. The order of ion concentration in precipitation is SO_4^2->NO_3^->Cl^-in case of anion and Ca^2+>NH_4^+ >Na^+>Mg^2+ in case of cation. It is found from our analysis that the correlation coefficient among the precipitation pH and ion components is below r=0.3, while the correlation coefficient between SO_4^2- and NO_3, Na^+ and Cl^- is above r=0.8, respectively. The mean pH of precipitation is 4.8 under the westerly wind and 5.2 under the easterly wind. The concentrations of anion and cation under the westerly wind are more than the concentrations under the easterly wind. In autumn, the concentration of Na^+ and Cl^- under the easterly wind are higher than the concentration under the westerly wind. The correlation coefficients between wind speed and pH, ion components show very low correlation of -0.41≤r≤0.2. But the present study show that the correlation coefficient between wind speed and pH of precipitation is positive and the correlation coefficients between wind speed and ion concentration is negative.

Catalytic slurry reactors, in which a solid maintained in the form of fine particles suspended in a liquid, are frequently used in chemical and biochemical and industries. In these processes the particle loading is normally low so that the effects of particles on the liquid-film mass transfer coefficent and the gas-liquid interface area are assumed to be negligible. But it is known from the works, amongst others, that the finely powdered activated carbon can increase the gas-liquid mass transfer significantly in surface-aerated reactors. The stirred cell (13.2cm inside diameter) contained four baffles and at the stirring speeds range of 80∼300rpm, the gas-liquid interfacial area could be considered as that of the cross section of the vessel (that is, 130.1㎝2). When the stirrer speeds were increased, the effective interfacial area was slightly higher than the geometric area and was obtained experimentally from the Danckwerts'plots.

李炳坤,文永守 慶北大學校 1985 論文集 Vol.39 No.-

According to the series of several recent studies, it has been clear that the urban climate in Korea has its own characteristics due to the industrial development and population growth since 1960's. By analyzing the secular variation of climatic elements of the four cities chosen in this study and comparing these with those of rural areas near the cities, it is attempted to clarify quantitatively the characteristics of the urban climate. The results are summarized as follows: (1) The annual mean temperature shows an increasing tendency in urban area. While it decreases in august, it increases in January. (2) The amount of annual precipitation in urban area seems to decrease. However, there is much more precipitation in cities than in rural area in August. (3) The relative humidity in urban area is slightly decreasing. The urban area is less humid than rural area, particularly in August. (4) The number of fog days shows no noticeable change in the secular variation of urban area. However, they are noticeably fewer in urban area than in rural area, particularly in August. (5) The mean wind velocity shows no conspicuous change in urban area. However, it is stronger than that of rural area in August. (6) In urban area there is a tendency that the annual mean percentage of sunshine has decreased for ten years since 1965, and it has increased again after that. However, it is worth noting that the percentage in August in urban area has decrease steadily since 1965. Furthermore it is lower than that in rural area, particularly in August.

This study attempts to divide precipitation regions of Korea by spring data and cluster analysis. The data used are the ten-daily mean precipitation of spring during the period of 1976-1985 taken by 60 weather stations of Korea Meteorological Service and the monthly mean precipitation of spring during the period of 1961-1980 taken by 240 precipitation stations of Construction Ministry. The results in this study are summarized as follows: (1) Seasonal precipitation regions of spring can be divided into 7 lst regions and 19 2nd regions. (2) The characteristics of divided regions are closely associated with the prevailing direction of air flow and the strike of mountain ranges. (3) Seasonal precipitation regions are simply divided compared to the annual precipitation regions.
