This paper shows eletrochemical extraction property changes of dyed cations by the various eletrochemical conditions using quartz crystal technique. The quantitative and qualitative changes of electrode surface was monitored measuring oscillation parameters of quartz crystal. The results suggest that the eletrochemical extraction of cation is influenced by the various factors such as ionic size, ionic intensity and tendency of ionization.

Recently the garlic has been proved to have some protective effect on the heavy metal poisoning of cadmium and mercury in several studies. From this fact it may be assumed that the garlic would have a protective effect to the toxicity of heavy metals in pregnant rat also. Therefore this study was designed to confirm the effect of garlic on the toxicity of cadmium in the pregnant rat and its fetus. The result of it was compared with that of 2,3-dimercaptosuccinic acid (DMSA). The experimental groups were devided into 3 groups; cadmium-alone treated group, cadmium-garlic combined treated group, cadmium-DMSA combined treated group. Each group was composed of 3 sub-groups according to the dosage of cadmium injection. The total of 4㎎/kg, 8㎎/kg and 16㎎/kg of cadmium was injected subcutaneously at the back of pregnant rat in each subgroup for 4 days, from the 14th to the 17th day of gestational period. Garlic and DMSA were administered per os from the day before cadmium injection to the 21st gestational day. The results of this study were as follows: 1. The inhibition of fetal growth due to cadmium administration into pregnant rat was prohibited in cadmium-garlic or cadmium-DMSA combined treated group except for the 16㎎/kg cadmium injected subgroups. 2. The accumulation of cadmium in tissues of liver, kidney and blood of pregnant rat, placenta and fetus was increased according to the increase amount of cadmium injection in all 3 experimental groups. Garlic and DMSA decreased the cadmium levels of maternal liver, kidney and blood, but there was no significant difference of cadmium level between garlic and DMSA treated group. 3. Garlic decreased the accumulation of cadmium in tissues of placenta and fetus, but it was not significant statistically comparing with that of DMSA or no-treatment group. Correlations of cadmium levels among maternal blood, placenta and fetus were positively high. 4. Necrosis of proximal convoluted tubules with pyknosis of epithelial cells was observed extensively in fetal kidney of cadmium-alone treated rat. However, the necrosis of the tubules was found only in small numbers of the tubules in cadmium-garlic combined treated one, but there was no remarkable change in cadmium-DMSA combined treated rat comparing with cadmium-alone treated one. As a conclusion this study revealed that the garlic would reduce the accumulation of cadmium in maternal tissues and protect against the toxic effect of cadmium at fetus in context of the growth inhibition and histopathological damage of kidney, but would not attribute the interfering the transportation of cadmium through placental barrier.

This study was performed to identify risk factors for depression among the elderly in a rural area. A survey was done for the elderly living in Gosam-myenn, Ansung-kun during the period of July 28, 1997 and July 30, 1997. Demographic and sodoeconornic characteristics, and functional and health Status were assessed using a structured questionnaire, and the level of depression was measured by GDS score. The data obtained were analyzed by frequencies, percentage, t-test, ANOVA, and multiple regression, and the results were as follows: 1. The total sample consisted of 133 elderly. Of them, 47 elderly (35.4%) showed significant depressive Symptoms. 2. The GDS score was the highest for the group over 85 years of age (p < 0.05). Those living alone or widowed showed lower GDS score than those living with someone or married (p < 0.05). 3. The GDS score was the highest in the absolutely dependent group, followed by the partially dependent group, and the independent group (p < 0.01). The elderly who perceived their health Status as excellent showed the lowest GDS score. In contrast, those who had more than five chronic diseases showed the highest GDS score. 4. The elderly receiving financial and emotional support from their family or friends showed lower GDS score compared to those without any support. 5. The economically dependent group showed higher GDS score than that of independent group. 6. The elderly who involved in leisure activities showed lower GDS score than those without any involvement. 7. In terms of risk factors for depression, we found that perceived health Status, subjective economic Status, leisure activities, living arrangement and financial support were inversely associated with GDS score, whereas labor support was positively associated with GDS score. Based upon the above findings, this study suggests that these risk factors for depression in the elderly should be taken into consideration for a comprehensive mental health program for the elderly living in the rural area.

An analysis of objection request of individual public land price in the Choongju-city indicates that the ratio of objection request is higher than that of an average of the whole country. More than 70% requests out of the total objection request fields requests downward adjustment. Especially, it has been requested downward adjustment centering around a farm and forest land which are located on the town and township for the purpose of tax reduction. However, an objection request of individual public land price is not based on the absolute land value but based on personal interests. Thus, the downward or upward request without a fundamental rule tends to wastes the time and budget. As an alternative, there is need to introduce the scientific system, ALPA, which both selects a comparative standard land and applies land value ratification automatically. With the ALPA, it will increase the confidence of individual public land price. Furthermore, there will be only one time verification procedure before the determination·public announcement of individual public land price.

소리내어 읽어주기 활동이 아동의 언어 이해력에 미치는 영향
송은경,이성은 이화여자대학교 사범대학 교과교육연구소 2006 교과교육학연구 Vol.10 No.1
본 연구는 소리내어 읽어주기 활동이 초등학교 중학년 아동의 언어이해력에 미치는 영향을 알아보는데 그 목적이 있다. 이를 위해 초등학교 3학년 두 학급을 선정하여 한 학급은 실험 집단으로 소리내어 읽어주기 활동을 적용한 국어 학습을 실시하였고, 또 다른 학급은 비교 집단으로 교사가 소리내어 책을 읽어주는 대신 아동 스스로 묵독을 통한 국어 학습을 8주 동안 적용하였다. 연구 결과, 소리내어 읽어주기 활동을 적용한 실험집단의 언어 이해력(듣기·읽기 이해력)이 비교집단보다 모두 통계적으로 유의미한 차이를 보여 소리내어 읽어주기 활동을 적용한 국어 학습이 아동의 언어이해력 증진에 긍정적인 변화들을 가져왔음을 알고 있다. 후속 연구로는 고학년의 아동들을 대상으로 소리내어 읽어주기 활용 방안을 개발하고 그에 따른 학습의 효과를 다양한 측면에서 검증할 수 있는 평가 방안에 대한 연구가 지속적으로 이루어지도록 제언하였다. The purpose of this study was to investigate the effects of reading aloud on the language comprehension-listening and reading- with elementary school students(3rd graders). For this purpose, subjects were chosen; 2 classes of 3rd grade in S elementary school, Dobong-gu in Seoul. Pre and test was developed to evaluate the ability of the language comprehension based on the 3rd grade Korean curriculum. The experimental group studies for 8 weeks 16 period by using Reading Aloud, the comparative group studied by using silent reading. As a result, these results pointed out that reading aloud help elementary school students(especially, 3rd grades) to improve their listening and reading comprehension. This means that Reading Aloud can be a good method for teaching the students that has poor in perceiving letters, as well as attaining comprehension<.001). In listening comprehension, the achievement of the experimental group shows significant difference from the comparative group. In conclusion, this study suggested that necessary to provide many literary works and to support and develop lots of reading aloud methods for enhancing comprehensibility.
