이 연구는 한국씨름의 기원을 밝히는 데 있다. 이를 위해 우리나라 씨름이 서역에서 왔는지, 씨름이 서역에서 온 것이라면, 구체적으로 어떤 곳에서 온 것인지를 유물을 통해 밝히고, 우리나라 씨름의 특징들을 분석하였다. 첫째, 서역인을 보지 않고서 그들을 벽화에 기록할 수는 없을 것이기 때문에 분명히 서역을 통해서 온 것이다. 씨름은 漢과 匈奴라는 두 제국이 분열하고 약화되면서 민족이 대이동하고 비교적 평화롭던 시기에 고구려로 들어온 것이다. 둘째, 문헌기록상으로는 각저라고 불리는 씨름은 AD 136년 부여를 통해 들어왔다. 그러나 씨름은 기원전부터 중국에서 유행하였고, 그것이 고구려에서 시행되었다. 셋째, 우리나라 씨름의 특징은 샅바라고 할 수 있다. 고대 이집트와 그리스 그리고 이란과 인도 등에서도 띠를 붙잡고 하는 씨름이 있었다. This study reveals the cultural anthropological origins of Korean wrestling Ssireum. For this purpose, where and when the Korean wrestling came from the western area, it is revealed through specific relics and analyzed the characteristics of Korean wrestling. The result is, firstly, that Korean wrestling Ssiruem certainly came through the western part because it would not be possible to record them on the tomb wall without seeing the westerner. And Ssirum was introduced that the two empires, Han(漢)and Huns(匈奴) were divided and weakened and during peace period of another two empires, Rome and Persia. Second, in the documentary records, Ssiruem which is called the Gakjeo(角?) introduced in Buyeo(夫餘) at AD 136. Gakjeo has been popular in China since BC, and it has been applied to Goguryo(高句麗). Third, the characteristic of Korean wrestling Ssireum is a belt called Satba. In ancient Egypt and Greece and Iran and India, there is a form of belt wrestling.

BACKGROUND: Earthworms are essential detritus feeders that play a vital role in the process of decomposition of organic matter and soil metabolism. The complex process of partial breakdown of organic matter and mixing with mucous and gut microbial flora in the form of earthworm cast results in the reduction of the toxicity. This study focused on the change of cast amount and pollutant contents before and after the eating of the organic waste and upland soil with the two species of earthworm. METHODS AND RESULTS: The two species of earthworms were compared to the cast production. In the upland soil material, the daily amount of worm’s cast was 1.42 g in E. andrei and 0.40 g in A. agrestis. In the organic waste material, the cast of E. andrei was 0.78~0.83 g and the cast of A. agrestis. have not been collected because all earthworms died after the treatment. The heavy metals treated in the upland soil were evaluated the impact of the worm excretion. With the E. andrei, the cast production was decreased 0.1~0.8 times in zinc, 0.2~0.5 times in copper, and 0.1~0.7 times in cadmium compared to the control treatment according to the levels of concentration. With A. agrestis, the cast amount was decreased 0.3~1.1 times in zinc, 0.2~0.3 times in copper, and 0.1~2.1 times in cadmium, respectively. The changes of pollutant contents before and after the eating of the organic wastes with E. andrei were studied. In the treatment of the Alcohol Fermentation Processing Sludge and the Fruit Juice Processing Sludge, heavy metal content of the cast was increased 0.7~53.3% compared to the sludge materials. PAHs contents were decreased 50.1% in the cast of the Alcohol Fermentation Processing Sludge and 36.6% in the cast of the Fruit Juice Processing Sludge, respectively. CONCLUSION: In conclusion, although the A. agrestis was bigger than E. andrei in size and weight, the cast amount of A. agrestis was small. The two species of earthworm was less excretion with high concentration of heavy metals. While the heavy metals such as zinc, copper, and cadmium were considerably accumulated in the cast, the total compounds, PAHs were fairly decomposed. There results would provide us for restoring contaminated soil and cleaning organic wastes.

체격을 측정하는 경우 여러 가지의 측정 오차를 발생시키는 요인들을 가정할 수 있다. 이러한 측정 오차는 측정도구, 측정시간, 측정자, 측정 참여자의 특성 등의 단일 요인 또는 복합적 요인에 의하여 발생할 수 있다. 측정오차의 원인을 규명하는 것은 측정의 신뢰도와 객관도 나아가 타당도를 제고하는데 많은 정보를 줄 수 있다. 본 연구는 체격, 특히, 신장과 체중의 측정상에서 발생되는 오차요인을 규명하는데 목적이 있다. 연구대상은 중학교 남학생 800명이었다. 측정도구는 신장과 체중 각각 두 종류의 다른 도구를 사용하였으며, 측정시간은 오전과 오후에 실시하고, 측정자는 전문가, 준전문가, 비전문가의 3 수준으로 하였다. 각 학생은 다른 측정도구(2), 측정시간(2), 측정자(3)에 의하여 2×2×3, 즉 12회 반복 측정되었다. 신장과 체중 측정에서의 오차요인은 양상이 각각 다르게 나타났으며 신장의 경우 측정시간에 따른 측정결과가 평균값의 차이를 나타내었고, 체중의 경우 세 요인의 복합적 상호작용에 의한 오차가 큰 것으로 조사되었다. There exist many possible measurement errors when physique is measured. The measurement errors can come from measurement instruments, different measurement time, and/or multiple measurers. This study was attempt to investigate the sources of measurement errors in physique measurement. Participants of this study were 800 middle school boys. Height and weight of a student were measured by two types of instruments and three measurers in the morning and in the afternoon. Measurement time was a major error factor for hight but for weight an interaction of three facets was a major error factor.

The purpose of this study is to describe the favor and disfavor experience that forms the attitude. For this study, I analyzed the stories of 150 learners' writing experience in first grade of middle school by using the qualitative research methods and verified the experiences that effected on the writing attitude separated by the before and after of school age period. For the writing learning in the before of school age, the attitudes toward teaching and reinforcement of educator, literacy environment and birth order in the family and others effected on the writing attitude of learner. For the writing learning in the after of school age, the dissatisfaction for the forced writing represented to the diary writing, social reinforcement and others effected on the writing attitude of learner. I should prepare the teaching method that can reinforce the favor affect and relief the disfavor affect.

This study was performed to investigate the effects of pine pollen and horseradish. which were known as antimicrobial materials, on the fermentation of Kimchi. The physicochemical and microbial changes of Kimchi were investigated during period 30-days at 10t. Even though Kimchi added pine pollen or horseradish powder were sustained the higher pH and lower acidity after 10 days, it delayed only I- 2 more days to reach optimal value of Kimchi fermentation in experimental groups than control. The horseradish powder showed the antimicrobial effect of Kimchi at initial stage, but thereafter that effect of pine pollen or horseradish were not significant. Therefore the addition of pine pollen or horseradish powder to Kimchi is not sufficiently effective for extension of shelf-life of Kimchi.
