IAEA가 제시한 중·저준위 방사성폐기물 천층처분시설 기준 안전성평가 사례에 대해 MASCOT프로그램을 이용하여 안전성평가를 수행하였다. 이를 위해 기준시나리오에 대한 개념 모델을 개발하였다. 지질계와 생태계의 연결매체인 우물을 통한 지하수 이동경로에 대한 평가를 수행하였고 생태계 모델에서는 구획모델을 적용하여 인간활동을 통한 최종 방사선적 영향을 평가하였으며, 다른 평가 결과와의 비교를 통해 기준시나리오에 대한 개념모델의 적합성을 조사하였다. 본 연구 결과는 구획모델을 이용한 지하수 유동경로에 대한 대표적인 개념모델을 총체적인 처분시스템의 안전성평가에 만족스럽게 이용할 수 있다는 것을 보여주었다. 또한 MASCOT프로그램을 이용하여 복잡하고 다양한 이동경로를 통한 천층처분시설의 방사선적 안전성평가가 가능함을 보였다. A reference scenario of vault safety case prepared by the IAEA for the near-surface disposal facility of low-and intermediate-level radioactive wastes is assessed with the MASCOT program. The appropriate conceptual models for the MASCOT implementation is developed. An assessment of groundwater pathway through a drinking well as a geosphere-biosphere interface is performed first, then biosphere pathway is analysed to estimate the radiological consequences of the disposed radionuclides based on compartment modeling approach. The validity of conceptual modeling for the reference scenario is investigated where possible comparing to the results generated by the other assessment. The result of this study shows that the typical conceptual model for groundwater pathway represented by the compartment model can be satisfactorily used for safety assessment of the entire disposal system in a consistent way. It is also shown that safety assessment of a disposal facility considering complex and various pathways would be possible by the MASCOT program.

Polyaniline and its derivative, poly(o-toluidine) have various molecular weights depending on the synthetic condition. The factors affecting on molecular weight are the kind of acid, the time of adding oxidant, synthetic temperature, etc. The acids of HCl, H2SO4, and H3PO4 were used. The synthetic temperature were room temperature, 0℃, and -10℃. The molecular weight of polyaniline was identified by GPC. The change of electrical conductivity depending on the change of molecular weight of polyaniline was studied.

The purpose of this study was to investigate of the dietary life, nutritional status and health condition in 100 elderly living in nursing homes in Pusan area. The quality of meals served in nursing homes base on nutrient contents and the state of preferared foods was evaluated by the questionaire and the nutritional status and health condition of subjects were estimated by the analysis of serum components. The results of this study are summarized as follows : 1. Almost all subjects were aged over 70 years and poor-educated. Mean height and weight of subjects were lower than Korean average standard but Body Mass Index(BMI) of those were normal and body fat contents of females were especially high. 2. Protein, vitamin A, vitamin C and Ca intake of subjects were lower than Korean RDA. Subjects preferred pan-broiled for meats and fishes, muchim for vegetables fruits as food between meals. 3. There were no smoking and drinking in almost all subjects. All subjects have taken nutritional supplements, mainly mineral supplements. Prevalence of disease in subjects were in the following order : cardiovascular, stomach, neuralgia in males. The frequency of neuralgia in females was highest. 4. Serum levels of HDI-cholesterol, total cholesterol, triglyceride, total protein, albumin, globulin, Ca and Mg were lower than those of normal ranges. Therefore, it is necessary to improve nutritional status of the elderly in nursing homes with by increasing the various side dishes and to develop the standard menu for those.

The retention of phenyl-substituted alkylammonium cations on a styrene-divinylbenzene copolymeric anion exchange column with acetonitrile-aqueous solution mobile phase was studied. The retention mechanism of ammonium cations was interpreted as a combination of ion exclusion and solvophobic interaction. The concentration of eluent anion and the retention of eluite cation showed good linearity in log-log coordinates. The slope was constant and was not affected by the nature of eluites nor kinds of eluents.

Ar+ ion irradiation on polymethylmethacrylate(PMMA) and polycarbonate(PC) was performed in an oxygen environment in order to improve wettability of polymers to water. Wettability was measured by water contact angle measurement, and the surface functionality was analyzed by X-ray photoelectron spectroscopy(XPS).The contact angle of water to polymer was modified by Ar+ ion irradiation in an oxygen environment. From the XPS analysis, it was concluded that the improvement of wettability is due to the formation of hydrophilic groups such as C-O and/or C=O on the surface of polymer.

On-line SPE-HPLC System을 이용한 Carboxamide류 농약의 연속 분석법 개발

金賢珠 충주대 산업과학기술연구소 1999 産業科學論文集 Vol.7 No.2

The analysis method of carboxamides herbicides using on-line SPE(solid phase extraction)-HPLC(high performance liquid chromatography) system was developed to improve selectivity and detection limit. The recoveries of nine carboxamides herbicides on six various adsorbents were examined. Band broadening which appeared with common on-line system was reduced by developing on-line SPE-HPLC system which permits the preconcentration of analytes and HPLC processing continuously with switching valve. The limit of detection could be lowered since all amounts of preconcentrated analytes were injected directly to HPLC system. XAD-2 was found to be the most efficient adsorbent for carboxamides. However, C18 was proved better precolumn than XAD-2 considering band broadening and calibration data. When C18 was used as a precolumn the recoveries of analytes were higher than 95% and the detection limit of 0.5 ppt was obtained for all compounds.

This study was performed to develope and applicate of food and culture education program that could help elementary school students to understand multi-culture. Developed Food and culture education program consisted of 11 lessons. The contents of the programs were as follows: Korean traditional food, Asia food, Western food and multi-culture etc. This program had been applied to a class of experimental group consisting of 6th graders. As a result of the study, the following findings have been made. Firstly, the students developed a great sense of pride for ones own culture and also learned through the process of cooking that there are many similarities as well as differences within family culture, from country to country. Secondly, the students able to experience a close connenction of intimacy with different group of people and various culture. The food and culture education program enabled the elementary school students to understand multi-culture and to improve the cognition and attitude significantly. Thirdly, most of the students also responded that their interests on food and culture, which proves the integrative educational effects significantly of the program. While the students developed an understanding for the diversity among culture, they also embraced a new respect towards other culture as well. After food and culture education program, students were satisfied and interested in korean traditional food and multi-culture. The positive effects on understand multi-culture and food knowledge of the elementary school students. It showed that programs of food and cultures for understanding multi-cultures can provide wide knowledge and indirect experiences about Korean traditional food cultures, foreign food cultures and various foods. Therefore, in the first-line of teaching this study will be a useful reference for various teaching method and contents for teachers to appropriately implement into their classrooms for the future.
