김태순,유장걸,송기준 한국농화학회 1979 Applied Biological Chemistry (Appl Biol Chem) Vol.22 No.4

The soils and plants were sampled from 26 sites of Deogpyeongri, Goisangun, which had been found to be one of the uranium deposit areas. Uranium levels of the samples were determined and the amount of uranium intake by the residents through the food-chains was estimated. The average uranium concentration of Deogpyeongri soils was 15.5ppm with a range of from 4.9 to 43.6ppm showing rather higher values than those of control area, Yangjugun and Icheongun, Gyeonggi-do. The average uranium content of the plant samples from Deogpyeongri was 0.69ppm, about twice the uranium concentration of the control samples. The daily intake of uranium by an adult lived on the agricultural food stuffs produced in Deogpyeongri, was estimated to be about 247㎍, eqivalent to 0.83×10^(-4)μCi, which is much higher activity compared to the daily intake cf uranium by New York citizen, 1.3㎍. However the calculated uranium level accumulated in the human body of Deogpyeong area was 2.03×10^(-4)μ which is still lower than 0.2μCi, the maximum permissible burden in total body recommended by the ICRP.

The weatherability and stability of the K-bearing and those secondary clay minerals in the Asan series soil of inceptisols are evaluated by the soil solution activity of Al3+as pAl3+under conditions at pK+=2.35, pH=5.0, and pSi(OH)4=3. The pAl3+values of orthoclase, muscovite and microcline are 0.2, 3.5 and 7.5 respectively. The minerals, therefore, increase in stability in the order: orthoclase, muscovite, microcline. Conversely, orthoclase show higher weatherability than muscovite or microcline. As for the clay minerals, the stability increase in the order: halloysite, gibbsite, illite, kaolinite, montmorillonite. The pAl3+are 6.4, 7.0, 7.4, 8.7 and 10.0 respectively. Comparing with the primary minerals most clay minerals maintain lower pAl3+than the former minerals. For 1 : 1 type minerals, halloysite weathers much more than kaolinite at the present time. Gibbsite is unstable under the current conditions because of the pSi(OH)4 value is less than that of 4.6 at equilibrium between kaolinite and gibbsite. Kaolinite, therefore, seems to be maintaining stability as a stable solid. In short, the current evaluation is agreed well with the order of stability that given by Goldrich. The lower K content of the soil as compared to that of reference soils also support the fact that weathering of K-bearing minerals caused considerable K leaching loss. Finally on the particle size distribution of K, much more K is concentrated in 0.1-0.062mm and below 0.062mm particle size fractions than 0.25mm or larger size fractions. The results could be explained that the mineral weathering is still going on and will continue.

土壤 우라늄에 관한 硏究

金台淳 건국대학교 1990 學術誌 Vol.34 No.2

The complete analysis of U, Si, Al, K, Mn, Fe, Mg, and Ca in twenty five series of the national typifying pedons, erects of the chemical and mineralogical characteristics of those parent rocks on the U concentration, the U with the soil taxonomic relation, and correlations with those elements were ewamined in this paper. The range of the U concentration of the soils (collected from 1964 to 1969) are 7.6∼12.2 ppm, 7.4∼13.1 ppm, and 7.4∼11.6 ppm in the A, B, and C horizons respectively. No clear differences of the U concentration among the h7ri2ons short, but it tend to be in the order of B>A>C horizons. The concentration of U in the soils shorts closer relation with the chemical and mineralogical compositions of the parent rocks, that is, the soils weathered from the acidic roocks which contain richer is Si and K, and poor in Fe and Mg show higher U concentration while the soils from the basic rocks which are richer in the mafic minerals than the felsic one and the sedimentary rock (tuff) are lower the concentration. In addition to the facts, the U concentrations of the alluvial soils which derived from the fluvial and the fluvio-marine deposits show the same trend with that of the soils from the acidic rocks. For the diluvial soils, the U concentration tends to be lower as compared to the above soils. Highly significant positive correlations with U and Si/Al mole ratio, and Si and K content are shown while highly negative correlations exist with the coil pH and Mn, Fe+Mg, and Ca content in the Boils.

^42K 同位元素 稀釋에 의한 K^+의 土壤吸着 特性

金台淳 건국대학교 1987 學術誌 Vol.31 No.2

This study was carried out to characterize K+ adsorption on soils with different pH, content of clay, and organic matter by 42K isotopic dilution method. Two slightly alkaline soils, Typic Haplaquent, Gwanghwal and Lithic Udorthent, Jangseong series, and remaining two strongly acid soils, Aquic udipsamment, Sadu and Aquic Hapludalf, Paju series were used for this study. The K+ adsorption on the soils, in the range of concentrations with 6.9~27.8μCi 42K l-1 and 253∼ 1014ppm K+ are fitted well on both of the Freundlich and the Langmuir adsorption isotherms. The amount of the Langmuir adsorption maximum are: highest in Jangseong series, Paju and Gwanghwal soils that show similar amount are come next, and the lowest in sandy Sadu soil. High pH and higher content of clay and organic matter, and prominent content of vermiculite in the Jangseong soil seemed to be attributed the highest K+ adsorption. For K+ holding strength, the Langmuir constant, however, that show weak possibly due to weak bonding on the organic matter in the soil. In the case of Paju and Gwanghwal soils, higher clay content with dominant 2:1 minerals and high pH seemed to be affected respectively much for K+ adsorption on both soils. As for sandy Sadu soil, lower clay content and dominant kaolinite may be caused on the lowest K+ adsorption.

Challenges of Marriage in Islam: A View from Social Cultural Anthropology

김태순 한국신학정보연구원 2019 Canon&Culture Vol.13 No.2

There is no shortage of literature on marriage in Islam, even when the subject matter is narrowed down to the development of Muslim marriage traditions on polygamy. A multiplicity of discussion also exists on disputes repudiation about the husband’s unilateral rights of divorce (talaq). Interestingly, not much literature is found on the topic of ‘temporary marriages’ despite its long-standing traditions within Islam, except for some studies focusing on the Shia’s infamous practice of ‘temporary marriages’ (muta nikah) known to cover-up legalized prostitution. Even less research seems to be available on the Sunni’s practice of ‘temporary marriages’ (misyar nikah) which have persisted nevertheless. Only very recently Sunni’s misyar began receiving attention from non-Muslim public media sources as the BBC. The question ‘What is marriage?’ is fundamentally asking who has the authority to govern the institution. While marriage is a sacrament for Christians, it is a civil contract for Muslims. The Christian idea of marriage as a sacred union between husband and wife is commonly expressed in the wedding vow, ‘until death do us apart,’ promises to keep the marriage bond as a covenant with and before God. The Islamic idea of marriage as a civil contract, rather than as a covenant, significantly weakens the religious dimension of marriage that would strengthen the marital duty. This article aims to present at least four essential categories of ideas about marriage which are particularly dissimilar between modern Islam and Christianity. The first category is brought to a focus by comparing how Christianity and Islam differ on the basic idea of marriage. The consequence of labeling marriage as a civil contract, while retaining the basic gender-biased structure and guideline, perpetuates injustice, rather than provide accountability. The last three areas have also been recently identified through non-Muslim societal norms and jurisprudence: ‘different kinds of marriages,’ ‘practice of polygamy,’ and ‘practice of divorce.’

流紋岩質 角礫凝灰岩 粉末에 의한 NH₄+, k+의 Langmuir 吸着과 ??脫着

金台淳 建國大學校附設 農業資源開發硏究所 1982 論文集 Vol.7 No.-

Kaolinite, Halloysite, Gibbsite를 主粘上鑛物로 含有하고 있는 田, 畓土壤의 物理化學性 改良材로서 流紋岩質 角礫凝灰岩 粉末의 有效性을 評價하기 위해서 ??, ??의 Langmuirg吸着 및 그것으로부터의 K 脫着特性을 檢討해 봤다. 粉末試料의 X線回折 分析 結果, 이 粉末에서 陽이온 吸着能을 가지고 있는 Clinoptilolite와 Mordenite가 檢出되었다. 또한 ??, ??이온 吸着은 Langmuir 等溫吸着이 適用됨을 確認했다. 凝灰岩 粉末의 Langmuir 最大吸着은 95∼129m.e./100g 범위였다. 또한 이 값은 試料의 陽이온 置換容量과 大體로 같았다. 吸着된 K를 IN-NH₄OAc로 4回 連續 浸出했을 때 K는 試料 중의 全加里의 52∼80%가 脫着되었다. 그런데 放出된 K量의 67∼70%는 1回 浸出때에 放出되었다. 즉, 양북(慶州地方), 금곡 및 마현(浦項地方)産地 試料는 각각 70.5%, 69.1%, 66.7%에 해당하는 K가 放出되었다. ?? and ?? adsorption by and ?? desorption from the rhyolitic tuff breccia powders were studied to evaluate its effectiveness as ameliorating material for soils which is involved dominantly kaolinite or halloysite, gibbsite and the others. Clinoptilolite and mordenite which is known to having the cation adsorptive power were identified by the X-ray diffraction analysis of the powdered samples. ?? and ?? ions adsorption by the samples could be confirmed to fit well the Langmuir adsorption isotherms. The values of the Langmuir adsorption maxima of the powders were in the ranges from 95 to 129 m.e./100g and that the values corresponded to those of the cation exchange capacities of the samples. As for desorption of K from the potassium adsorbed powders, 52 to 80 percent of total K could be released during four times of successive extractions by using IN-NH₄OAc solutions. 67 to 70 percent of the potassium released, however, could be desorbed by the initial IN-NH₄OAc extraction.

Diphenylhydantoin의 造血能에 미치는 影響

金台淳,黃基錫 慶北大學校 醫科大學 1974 慶北醫大誌 Vol.15 No.2

① 體重 kg當 5mg의 diphenylhydantoin을 經口的으로 每日 4週間 投與한 實驗群에서도 血色素値, 好中球 絶對數 및 血小板數에 있어서 4週間에 걸쳐 有意한 變動이 없었으며 骨髓의 巨核球數, 骨髓球系細胞數, 赤芽球系細胞數 및 赤血球 ^59Fe 利用率에 있어서도 對照群에 比하여 有意한 差가 없었다. ② 體重 kg當 50mg의 diphenylhydantoin을 經口的으로 每日 4週間 投與한 實驗群에서는 血色素値는 뚜렷 한 減少가 있었으나 好中球絶對數 및 血小板數에 有意한 變動이 없었다. 그리고 骨髓의 巨核球數 및 骨 髓球系細胞數는 對照群에 比해 有意한 差가 없었으나 赤芽球系細胞數 및 赤血球 ^59Fe 利用率에는 有意 한 差가 있었다. ③ 體重 kg當 50mg의 diphenylhydantoin을 每日 經口的으로 4週間 投與하고 同時에 體重 kg當 0.1mg의 葉酸을 每日 筋肉內로 4週間 投與했던 바 diphenylhydantoin으로써 誘發된 貧血에 對하여 葉酸의 治療的 效果는 없었다. 上記 實驗成績으로서 diphenylhydantoin을 大量으로 흰 쥐에게 投與하는 境遇에는 赤芽球性無形成을 일 으킬 수 있다는 것을 알 수 있었다. Diphenylhydantoin was administered to male albino rats in order to study its effect on the hematopoiesis and to evaluate the effect of folic acid on the anemia induced by the drug with the following results. 1. Control rats receiving no medication revealed no significant changes in hemoglobin, absolute neutrophil count and platelet count during a period of four weeks. 2. Rats receiving diphenylhydantoin orally at a dose of 5 mg per kg daily disclosed no significant changes in hemoglobin, absolute neutrophil count and platelet count. Also no appreciable differences were noted in marrow megakaryocyte count, erythroid cell count, myeloid cell count, and erythrocyte ^59Fe incorporation as compared with those of the control rats. 3. Rats receiving diphenylhydantoin orally at a dose of 50mg per kg daily for four weeks showed a marked decrease of hemoglobin level whereas no significant alterations were observed in either the absolute neutrophil count or the platelet count. The examination of both erythroid cell count and erythrocyte ^59Fe incorporation showed significant changes as compared with those of the control rats, whereas the marrow megakaryocyte count, and the myeloid cell count revealed no significant alterations. 4. Rats receiving concomitantly diphenylhydantoin orally at a dose of 50mg per kg and folic acid intramuscularly at a dose of 0.1mg per kg daily for four weeks revealed that folic acid was not effective in ameliorating the anemia induced by diphenylhydantoin. 5. It is concluded from the aforementioned experimental data that rats receiving the administration of large doses of diphenylhydantoin could develop erythroid aplasia.
