In this paper, we deal with various contents relating to the group concept in school mathematics and teaching of algebraic structures indirectly by combining these contents. First, we consider structure of knowledge based on Bruner, and apply these discussions to the teaching of algebraic structure in school algebra. As a result of these analysis, we can verify that the essence of algebraic structure is group concept. So we investigate the previous researches about group concept: Piaget, Freudenthal, Dubinsky. In our school, the contents relating to the group concept have been taught from elementary level indirectly. Tn elementary school, the commutative law and associative law is implicitly taught in the number contexts. And in middle school, various linear equations are taught by the properties of equality which include group concept. But these algebraic contents is not related to the high school. Though we deal with identity and inverse in the binary operations in high school mathematics, we don't relate this algebraic topics with the previous learned contents. In this paper, we discussed algebraic structure focusing to the group concept to obtain a connectivity among school algebra. In conclusion, the group concept can take role in relating these algebraic contents and teaching the algebraic structures in school algebra.

The aim of this work was to assess the Delvo test for the detection of antimicrobial residues in goat milk. A total of fifty six samples (eight farms, seven samplings each) were analyzed by the Delvo, Eclipse 100, and Parallux tests. None of the samples showed positive results with the Parallux test which is based on immune-chemical methods. However, 37.5% of samples showed positive results with the Delvo test. 3.6% of samples showed positive results with the Eclipse 100 test, which is based on a microbiological method. The Delvo test is included in the 'standard methods for the examination of raw milk' by the National Veterinary Research and Quarantine Service as a microbiological method used for the detection of antimicrobial residues. Because "raw milk" is defined as 'milked state of cow, ewe and goat milk for sale or for processing' in the Animal Food Products Processing Law, the Delvo test should be excluded from the 'standard method for the examination of raw milk', or additional official documents referring to the Delvo test as not appropriate for the detection of antimicrobial residues of goat milk are required.

Objective : Ten heavenly stems and twelve earthly branches are the important means to understand the orders of changes in heaven and earth. Method : We have so far looked into detailed explanations about twelve earthly branches in Seolmunhaeja, annotations in Seolmun of four major people, and commentaries in Jeongyeokwonui. Result & Conclusion : This can be also applied to the explanations of twelve early branches, as follows. In the $11^{th}$ month of the lunar calendar, the yang energy is finally born amid full of the ying energy. In the $12^{th}$ month, the yang energy prepares to break through the knots of the ying energy and gets ready to come out of the ground. In the first month, three kinds of the yang energy start to become vigorous and active. In the second month, the yang energy gains more force, sprouting various plants on the ground. In the third month, the yang energy arouse further, strengthening and growing plants. In the fourth month, all the yang energy is released, while the ying energy is still hiding. In the fifth month, one ying energy is born amid full of the yang energy, and there are interchanges between the yang energy and the ying energy. In the sixth month, the yang energy is still strong and vigorous, ripening the fruits in the fields. In the seventh month, the yang energy starts to hurt all creation. In the eighth month, the ying energy starts to flourish, and the yang energy starts to decline, diminishing all creation and, however, still ripening grains to be harvested. In the ninth month, one yang energy starts to hide from sight, not working its duty, while five kinds of the ying energy start to annihilate all creation. Finally, in the tenth month, the small yang energy hides to be rebirthed amid the flux and reflux of the ying-yang energy. The creative and unique interpretation of Jeongyeokwonui about twelve earthly branches is worth to be referred. It is definitely beyond the other existing explanations, as it incorporates trigrams and hexagrams from I Ching (Book of Changes) and the five primary substances.

The purpose of this study is to produce a better way to detect crossroad accidents, which involves an efficient method to produce background images in consideration of object movement and preserve/demonstrate the candidate accident region. One of the prior studies proposed an employment of traffic signal interval within crossroad to detect accidents on crossroad, but it may cause a failure to detect unwanted accidents if any object is covered on an accident site. This study adopted inverse perspective mapping to control the scale of object, and proposed different ways such as producing robust background images enough to resist surrounding noise, generating candidate accident regions through information on object movement, and by using edge information to preserve and delete the candidate accident region. In order to measure the performance of proposed algorithm, a variety of traffic images were saved and used for experiment (e.g. recorded images on rush hours via DVR installed on crossroad, different accident images recorded in day and night rainy days, and recorded images including surrounding noise of lighting and shades). As a result, it was found that there were all 20 experiment cases of accident detected and actual effective rate of accident detection amounted to 76.9% on average. In addition, the image processing rate ranged from 10~14 frame/sec depending on the area of detection region. Thus, it is concluded that there will be no problem in real-time image processing.

Among finite filed arithmetic operations, division/inverse is known as a basic operation for public-key cryptosystems over $GF(2^{m})$ and it is computed by performing the repetitive $AB^{2}$ multiplication. This paper presents a digit-serial-in-serial-out systolic architecture for performing the $AB^2$ operation in GF$(2^{m})$. To obtain L×L digit-serial-in-serial-out architecture, new $AB^{2}$ algorithm is proposed and partitioning, index transformation and merging the cell of the architecture, which is derived from the algorithm, are proposed. Based on the area-time product, when the digit-size of digit-serial architecture, L, is selected to be less than about m, the proposed digit-serial architecture is efficient than bit-parallel architecture, and L is selected to be less than about $(1/5)log_{2}(m+1)$, the proposed is efficient than bit-serial. In addition, the area-time product complexity of pipelined digit-serial $AB^{2}$ systolic architecture is approximately $10.9\%$ lower than that of nonpipelined one, when it is assumed that m=160 and L=8. Additionally, since the proposed architecture can be utilized for the basic architecture of crypto-processor and it is well suited to VLSI implementation because of its simplicity, regularity and pipelinability.

Thinning of apple fruitlets is one of the most laborious and important works for the improvement of fruit quality and for the promotion of sufficient flower bud formation to prevent alternate bearing in commercial cultivars. Lateral fruits of self-thinning apple cultivars fall naturally within 30 days after full bloom and only central fruit remains to mature. Differences of gene expression between central fruit and lateral fruit were investigated by differential display (DD) PCR. Partial cDNAs of 30 clones from the central fruit and 24 clones from the lateral fruit were selected for nucleotide sequence determination and homology searches. The levels of transcripts coding for proteins involved in pathogenesis related proteins, senescence, temperature stress, protein degradation, fruit browning, sorbitol metabolism were significantly higher in pedicels of lateral fruit than in pedicels of central fruit. On the other hand, the up-regulation of proteins involved in anthocyanin and flavanol biosynthesis and ethylene synthesis were observed in pedicels of central fruit. In Real time PCR analysis, cytochrome P450 gene was confirmed as showing a higher expression level in lateral fruit than in central fruit. The results of this study indicate that differentially expressed genes are related to self-thinning characteristics in apple tree.

This study is an analysis of Mengshan heshang analects. Mengshan heshang lived in Song(?) and Yuan(?) Dynasty and he was a Buddhist monk of Linji Chan(???). His works handed on Buddhist monks of Goryeo in the late Goryeo Dynasty. And he influenced Buddism in the early Joseon Dynasty. In Joseon Dynasty Mengshan heshang Sermons abstract was confirmed existence of 39 editions and Mengshan heshang Liudao Pushuo was confirmed existence of 24 editions. All 63 editions show that Sermons abstract and Liudao Pushuo are his representitive analects. All editions were printed in early Joseon Dynasty. At that time Mengshan heshang analects was distributed in Joseon Dynasty. Mengshan heshang analects was distributed in all over the nation as well as in Royal Family of Joseon. Also Mengshan heshang analects was published many times in the Mt. Jiri area. The names of almost engravers found on the publications of many temples. Some engravers actively participated in publishing Buddhist scriptures in particular area. His ideas were received in the late Goryeo Dynasty and the early Joseon Dynasty actively and his many works appears like this.

In this study, I examined the visual elements for narrative structure and the symbols, scene components and visual styles in the images through analyze the flat staging in Tomm Moore's animated feature film, . As a research method, I figure out the general theories about staging and analyze extracted scenes which revealed flat staging in the , then summarize and clarify the flat staging production elements and features of Tomm Moore. As a result, in , the composition of the screen using the basic shapes, the screen composition containing the spiral which is symbol of the Celtic traditional pattern, the stable and flat frame expression through the balanced screen composition, expression of spatial sensation using perspective, appearance of the period by using the inverted perspective, and composition that can emphasize the flat formability are appeared as a characteristic. Through this, the two-dimensional planarity was maximized to convey the feeling of appreciating the illustrations of fairy tales. Tomm Moore, who produced animation based on folk tales in order to inherit the traditional culture of Ireland, has been attracting worldwide attention because of its flat staging to help narrative, enhancing the original expression and performance of animation. I hope that this study will be used as basic data for industry workers and researchers who make unique and excellent animated feature film.

This study Dasan Jeong Yak-yong, great writings, "Mokminsimso" and " Kyoungseyupyo"argued for reform of Dasan Jeong Yak-yong's tax law is a series of Surtax that have been included in or not in the law and have aggravated the tax burden on the people. Dasan Jeong Yak-yong's reform drive for the tax law did not end with a desk discussion, but went so far as to scrutinize the tax data in Gangjin, Jeolla-do, where he was in exile, and present various measures to abolish taxes and improve them in "Mokminsimso" and "Kyoungseyupyo". Based on the details of the tax laws for Dasan Jeong Yak-yong, "Mokminsimso" and "Kyoungseyupyo" this study reviewed the tax data and related prior research that Dasan Jeong Yak-yong investigated during his exile in Jeolla-do, The method of collection of various Surtax and the definition of tax amount and character of the Joseon Dynasty, which were insufficient in the preceding study, was modified and supplemented. and further summarized various Surtax that were not mentioned in the preceding study. In addition, similar and opposite Surtax found in the review process of this study were compared in the text. also, various Surtax collected from the Min-go that increased the tax burden of the people at that time were summarized.
