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.
사회복지현장실습이 사회복지전공학생들의 진로발달 및 전문직업의식에 미치는 영향

The purpose of this study is to investigate the effectiveness of social work practicum by examining influences of social work practicum on career development. Specifically, this study examined the relationships between the factors affecting social work practicum such as students, supervision, institution, and college, and the career development and professional consciousness of social welfare. The targets for this study were arbitrarily chosen from among social welfare students in third and fouth grade with practicum experience. Answers from 280 respondents were analyzed for the study and the collected data were statistically processed through SPSS 12.0 Analysis. The study showed that the levels of career development and professional consciousness of social welfare were little bit lower than average. The satisfaction levels of supuervision, practicum class, and student's major selection were significant predictors of students' career development. Also, the satisfaction levels of supuervision, practicum class, and student's major selection and the appropriateness of practicum contents in the field were significant predictors of students' professional consciousness of social welfare. In conclusion, the quality of supervision and the substantiality of practicum class are very important for improving the levels of students' career development and professional consciousness of social welfare. Finally, several theoretical and practical implications, suggestions for future studies, and limitations of this study were presented 본 연구의 목적은 사회복지현장실습 경험이 사회복지전공학생들의 진로발달과 전문직업의식에 어떠한 영향을 미치는지를 살펴보고자 함이다. 구체적으로 실습 주요요인이라고 밝혀진 학생요인, 기관요인, 수퍼비전요인, 학교요인이 학생들의 진로발달과 전문직업의식과 어떤 관계가 있으며 그 영향력은 어떠한지 살펴보았다. 연구결과, 사회복지전공학생들의 진로발달과 전문직업의식 수준은 보통수준에 약간 못 미치는 것으로 나타났다. 진로발달의 경우 수퍼비전 만족도, 학교실습수업 만족도, 실습생의 전공선택 만족도가 유의한 영향을 미치는 변수로 나타났으며, 전문직업의식의 경우 수퍼비전 만족도, 학교실습수업 만족도, 실습생의 전공선택 만족도, 기관의 실습내용 적절성이 유의한 영향을 미치는 것으로 나타났다. 이러한 연구결과를 바탕으로 앞으로 사회복지전공학생들의 진로발달 및 전문직업의식의 증진을 위하여 보다 질 높은 수퍼비전의 제공과 학교 실습수업의 내실화가 무엇보다도 선행되어야 함을 제안하였다. 또한 본 연구의 이론적, 실천적 함의와 더불어 후속연구를 위한 제언과 연구의 제한점을 제시하였다.
Points at infinity of complete open Riemannian manifolds
김태순,전명진 한국수학교육학회 2004 純粹 및 應用數學 Vol.11 No.4
For a complete open Riemannian manifold, the ideal boundary consists of points at in¯nity. The so-called Busemann-functions play the role of distance functions for points at in¯nity. We study the similarity and di��erence between Busemann-functions and ordinary distance functions.

Two methods for the determination of Cesium-137 in various foods(ashes) were compared. The one comprises two steps, the first being the separation of alkalies as cobaltinitrites or perchlorates by the radiochemical method, and the second being the measurement of photopeak area due to the presence of Cs-137 by the use of scintillation spectrometer. The other method is the direct subjection of ash samples to the spectrometry without the radiochemical separation. The combined contribution of K-40 and Rb-87 to the spectrum was not found on account of the difference in energies of these nuclides. These two methods gave, a good agreement in the determination of Cs-137 in 50-100g ash samples of vegetables or cereals under investigation.
