The purpose of this study was to examine the effect of vegetable gardening activities for 4-years-old children. For this purpose, this study is focused on learning how effect vegetable gardening activities on 4-years-old children`s science-related attitude and scientific exploration ability. To examine this purpose, the following research questions were investigated: 1. How effects does vegetable gardening activity make on 4-years-old children`s science-related attitudes? 2. How effects does vegetable gardening activity make on 4-years-old children`s scientific exploration ability? The Subjects were fifty children from 2 classes of B kindergarten in Jung-gu, Daejeon. The subject were experimental group consisted of 25 children, while control group consisted of 25 children whose average age 4 years 10 weeks. Measuring tools for this study included the science-related attitude test and the scientific process skills test. For the science-related attitude test researcher modified `Instrument for science-related attitude test` which Che,Jung-yeon had made in 2003 on the basis of Kim, Hyo-nam`s Chung, Wan-ho`s Jeong, Jin-Woo`s national assessment system of science-related affective domain in 1999. And for the scientific exploration ability test researcher modified `Instrument for scientific exploration ability test` which Lee, Kyoug-min had made in 2000 on the basis of Martin`s scientific exploration ability evaluation benchmark in 1997. To verify young children`s science-related attitude, after coming up with score`s difference of pretest and posttest of science-related attitude, executed t-test. To verify young children`s scientific exploration ability, after coming up with frequency and percentage of scientific exploration ability, executed X2-test. The result of study are as follows. First, vegetable gardening activity theory exerted positive effects on 4-years-old children`s science-related attitude. there was also a positive effect as the children`s interest in science, desire to learning more about science, science-related jobs and science-related problems issues increased. However, there was no positive effect on science-related activities. Other positive effects on attitudes to science 4 year old children did vegetable gardening, it increased sense of curiosity, ability critically think, ability to cooperate and ability to volunteer. However, there were no effects on the children`s openness to new ideas, patience and creativity. Second, vegetable gardening activity theory exerted positive effects on 4-years-old children`s scientific exploration ability. this had positive effect as the children`s ability to predict, classify, measure, and discuss improved, but there were no effects on their ability to observe.

오세진(Se-Jin Oh),김성철(Sung-Chul Kim),고주인(Ju-In Ko),이진수(Jin-Soo Lee),양재의(Jae E. Yang) 한국토양비료학회 2011 한국토양비료학회지 Vol.44 No.6

본 연구는 다량의 중금속을 함유하는 폐석탄 광산에 적치된 폐석으로부터 발생하는 침출수의 안정화를 위해 석탄회를 안정화제로서의 적용성을 평가하는데 목적이 있다. 석탄폐석에 석탄회를 적용하여 컬럼시험을 수행한 결과는 다음과 같다. 1) 석탄회의 pH는 비산재와 바닥재가 각각 11.1, 9.7의 강알칼리성을 갖는 것으로 나타나 강산성 조건의 폐석 (pH 3.5)를 교정하였으며 유기물을 비롯하여 식물생장에 필요한 영양소인 인산, 칼슘 등을 함유하는 것으로 나타나 폐석과 혼합할 경우 비옥도가 개선될 수 있을 것으로 판단된다. 2) 폐석만을 충진한 컬럼에서 발생하는 침출수의 pH는 3.5~4.0의 수준을 시험기간 동안 지속적으로 유지하는 것으로 나타나지만, 석탄회의 처리량에 따라 40% (pH 5.0~6.0) 〉 20% (pH 4.5)로 나타나고, 동일 처리량 (40%)의 처리방법에 따른 효율성은 완전혼합 (pH& & 5.0~6.0) 방법이 층위처리 (pH 4.0~4.5)에 비해 pH 상승효과가 높은 것으로 조사되었다. 3) 침출수의 Ca과 Mg의 함량은 4 pore volume까지 빠르게 용탈되다 그 이후부터 안정화 되었으며 석탄회에서 용탈된 Ca과 Mg의 영향으로 폐석에 함유되었던 Cu, Pb, As, 및 Al 등이 탄산이온 (CO₃<SUP>2-</SUP>) 또는 수산화이온 (OH-)과 불용성 화합물을 형성하여 안정화 되는 것으로 사료된다. 4) 철의 용존함유량에 대한 분석결과 석탄회 처리구의 용존량이 석탄회를 40% 층위처리한 처리구를 제외하고 대조구에 비해 약 8-74% 정도 감소하는 것으로 조사 되었다. 5) 석탄회를 이용한 폐석의 중화 및 철의 용존량 감소 효율성을 평가한 결과 폐석의 중화 효율성은 석탄회를 40% 완전혼합한 경우 가장 높았으며 철의 용존량 감소 효율성은 석탄회를 20% 완전혼합한 경우가 가장 좋은 것으로 조사되었다. 따라서 석탄회를 이용하여 현장에서 폐석을 처리할 경우 약 20-40%의 석탄회를 처리해야 높은 효율성을 얻을 수 있을것으로 사료된다. In this study, coal combustion ash (CCA) was evaluated for its stabilization effect on acidic mine waste with column experiment. Total of six treatments were installed depending on mixing ratio between coal wastes and CCA (0, 20, 40%) and mixing method (completely mixing and layered). Artificial acidic rain (pH 5.6) was used for feeding solution with flow rate of 0.05 mL min<SUP>-1</SUP>. Result showed that higher pH of leachate was observed as more CCA was mixed. The highest pH in leachate was measured when 40% of CCA was mixed with coal waste (pH of 5.8). Also, complete mixing with CCA and coal waste was more effective to increase the pH of leachate than layered treatment. Regarding the reduction of soluble Fe amount, the highest efficiency (78%) was observed when 20% of coal ash was completely mixed with mine waste. Based on those result, optimum mixing ratio of coal ash with mine waste can be ranged 20-40% depending on environmental circumstances in the field.

This study focuses on Comparative of conventional Agriculture and Organic Farming Among various kinds of environmentally sound farming practices the organic and Conventional Agriculture practices are chosen for this study. The main objective of this study is to evaluate the technological systems of organic farming practice in order to find the possibility of extending such technological system to the general farmers. Compared with the general farming practices, the organic farming requires many special technologies. Among them, technologies relating to compost making, pest, insect and weed control are different from those fo general farming practices. New technologies for the improvement of organic farming practices are developed or and imported from abroad by the organic farming association. As far as technology development for the organic farming, many research organizations between the goals of technology development of the conventional and organic farming system. In other words, land productivity of the organic farming technological system is lower than that of the conventional farming technological system.

Sleep is an essential component in health and the quality of life of individual. Normally, sleep pattern changes with advancing age. These changes often result in sleep impairment and become a major stressor in elderly. Even though the elderly is the fastest growing population, sleep impariment among elderly has not been well documented, few studies have been conducted related to the sleep of the elderly in Korea. The purpose of this study is to explore sleep pattern, related factors, and sleep satisfaction among healthy community-dwelling elderly, in order to present basic informations regarding Korean elder's sleep. 170 subjects over 60-yer-old were participated in the study. The survey questionnaire was developed by translation and modification of two well-known sleep questionnaires which originally developed by Monroe(1967) and Ellis, et al.(1982). Pilot study was done liefore final contents of a questionnaire was organized. SPSS/PC+ was utilized for data analysis. Results as follows: 1. Sleep pattern changes were reported by 75% of the subjects: decline in sleep time: frequent awakening: difficulty in falling asleep; lack of deep sleep; falling asleep early and getting up early; sleepy; decline in early morning sleep; irregular sleep habit; early retiring in bed. 2. Most of the subjects reported to fall asleep between 9-11pm, and get up between 4-6am. Forty point one percent of the subjects stated that they have problems in falling asleep. More than 70% reported their sleep to be satisfied. Sixty one point eight responded that they hardly or never take a nap. 3. Regarding sleep-disturbing factors, physical factor(30.1%), emotional factor(44.2%), environmental factor(41.0%) were reported. 4. Nineteen point two of the subjects practiced some types of strategies for better sleep. But a few(12.8%) used hypnotics, mainly in occasional base. 5. Variables showed statistically significant differences in sleep satisfaction were; getting up right away upon waking; frequency of awakening during night time sleep; difficulty in falling asleep; feeling rested upon waking int eh morning ; difficulty in going back to sleep upon awakening during night time sleep. From the results of this study, it can be concluded that the elderly in the community do have some sleep impairment but do not practice adequate strategies for better sleep. Further research are needed to develop better sleep measurement tool, to compare sleep pattern with other age groups and to develop nursing intervention.

Thyrotoxic periodic paralysis occurs primarily in Orientals with an overwhelming male preponderance and a higher association of specific HLA antigens. Clinical manifestations include onset after high carbohydrate ingestion or heavy exertion with progressive symmetric weakness leading to flaccid paralysis of the extremities and other muscle groups, lasting several hours. Other precipitating facters include trauma, infection, administration of epinephrine, thyroid hormone, or corticosteroid. If hypokalemia is present, potassium administration may help abort the attack. Although propranolol can be efficacious in preventing further episodes, the only definitive treatment is euthyroid state. The pathophysiology is still controversal, but reflects altered potassium and calcium dynamics as well as certain morphologic characteristics within the muscle unit itself. We discribed two patients with thyrotoxic periodic paralysis who had a no familial history of paralysis and had a decreased level of serum potassium during attack.

The structure of sodium trans-bis(methyliminodiacetato) chromate(Ⅲ), C_10H_14O_8N_2CrNa, has been elucidated with two space groups P 1-; a=8.9856(6), b=13.308(1), c=6.261(1)Å, α=76.38(1), β=110.361(9), r=107.394(6)˚, V=662(2)Å^3, Z=2, μ=0.47mn^(-1), d=1.831Mg/㎥, R=0.0295 for 1901 independent reflections with F^2>2σ(F^2), and A2/n; a=13.65(5), b=6.261(1), c=16.85(6)Å, β=113.05(1)˚, V=1324(7)Å^3, Z=4, R=0.0287 for 1013 independent reflections with F^2>2σ(F^2). There are two different asymmetric half molecules in triclinic system and one asymmetric half molecule in monoclinic system. The structures of three different molecules are very similar in conformations. The four carboxyl O atoms and the two imino N atoms in each molecule produce a distorted octahedral coordination geometry around the Cr atom. The average distances of Cr-O(carboxyl) and Cr-N(imino) are 1.956 and 2.061Å respectively. Molecules are held together by ionic forces. In this paper, it has been also shown that the cell constants, Miller indices, atomic coordinates, lattice directions and reciprocal lattices of the two space groups can be mutually transformed.

1999년 10월에서 11월 사이에 남해안 일대의 홍민어 종묘 생산장에서 20~30열령의 치어가 척추만곡 및 이상유영을 하며 대량 폐사하였다. 병어는 특이 외부 증상이 없었고, 높은 누적폐사량이 바이러스 질병으로 의심되어, 조직학적 및 분자생물학적인 검사를 행하여 폐사원인을 확인하였다. 폐사개체의 조직을 H-E 염색하여 관찰한 결과 뇌와 안구의 신경세포에서 공포와 괴사가 관찰되었고, 전자현미경 관찰에서는 안구와 뇌에서 바이러스 입자가 관찰되었다. RT-PCR 결과에서는 ≒426 bp의 DNA 단편을 확인할 수 있었다. 이러한 결과로 홍민어에서 발생한 대량폐사는 바이러스성 신경괴사증(VNN)으로 진단되었다. Mass mortalities occurred among red drum lavae, 20 to 30 days old, culturing at hatcheries on southern costal area. No specific external signs were observed except abnormal swimming and spinal deformity. It was, however, suspected as a viral etiology due to high mass mortalities so that histopathological and molecular biological study was performed to evaluate the agent. Both vacuoles and necrosis were observed on nerve cells of brain and eye by H-E staining, and viral particles were observed on electronmicroscopic examination. On the other hand, DNA fragment, approximately 426 bps, was amplified with RT-PCR. The above results were able to diagnosis the etiological agent of mass moralities in red drum larvae as VNN(viral nervous necrosis)virus.
