The antibacterial activities of methanol extract and systematic solvent fractions(-hexane, chloroform, ethyl acetate, and butanol) from Korean common type figs at different ripening stages were tested by the broth dilution method against 8 representative food-poisoning bacteria- : L. monocytogenes, S. aureus, S. enteritidis, E. cols 0157:H7, E. cols, Y. enterocolitico, V. parahaemolvticus, and S. ttphimurium. The methanol extracts of unripened Ⅰ and Ⅱ showed stronger activity than that of the ripened figs especially against L. monocytogenes, S. enteriridis, E. toll 0157:H7, V. parahaemolvticus and S. nphimurium in 10 mg/mL. The systematic solvent fractions showed stronger antibacterial activities than the methanol extract, even at the lower concentrations. The hexane fraction of ripened Figs showed higher growth inhibition than those of unripened Ⅰ and Ⅱ against L. monocytogenes, E. colt 0157.117, Y. enterocolitica and V. parahaemolvtieus. The chloroform fraction showed strong antibacterial activity in all ripening stages against E. soli 0157:H7 and V. parahaemolyticus. The butanol fraction showed better inhibition activity in unripened I and II than in the ripened figs. The hexane and chloroform fractions showed inhibition activity of more than 75% against E. coli 0157:117, V. parahaemohvicus in 0.5 mg/mL. Each fraction showed a little different antibacterial activity according to the ripening stages of the fruits and the tested strains. Especially, rigs in the unripened II stage revealed superior activity relatively and the hexane and chloroform tractions revealed the strongest activity, followed by the butanol fraction, while the ethylacetare and water fractions hardly showed any activity.

Fig(Ficus carica L.) which belongs to Moraceae family has been used as digestion promoter, cure for ulcerative inflammation and eruption in Korea. Figs have very short preservation period and can be kept only 1 week even in the refrigeration system. The possibility of wine-making from Korean figs was tested by analyzing the fermentation characteristics, proximate analysis and free sugar contents of wine made of slices with 20% sugar addition. Ethanol fermentation of the figs by Saccharomyces cerevisiae was done rapidly. The ethanol contents, pH, total acidity and sugar content were 12.1%, 3.91, 0.42% and 9.9 °Brix, respectively. The results from the sensory evaluation were as follows. The wine made from the sliced figs were better than that from fig juices in their sensory scores. The wine made with frozen figs was not different from that made with fresh ones. To improve the quality of wine, the addition of dried leaf powder in the concentration of 100 ppm were tried and found it was superior to the one made without leaf.

먹는샘물, 먹는물중의 이온함량 조사

정란경 慶熙大學校 地球環境硏究所 1998 지구환경논문집 Vol.9 No.-

물 속에는 함유하고 있는 다양한 물질 중 음이온(F, Cl, NO_3-, SO_4)을 중심으로, 국내 시판되고 있는 먹는샘물과 먹는 물 중의 함량을 조사하는 효율적 방법을 연구하였다. 먹는샘물 15개의 경우 각 이온별 기준치 초과가 없었으나 먹는물 150개의 경우 불소는 2.6% 기준을 초과했고, 염소이온의 경우 1.3% 기준을 초과했다. 질산성질소의 경우 9.3%나 되었고 황산이온의 경우는 기준치 초과가 없었다. 각 이온 성분별 분포에서 불소는 먹는 샘물의 경우 불검출~1.2ppm의 분포를 보이고, 먹는물은 불검출~2.6ppm으로 나타났고, 염소이온은 먹는샘물이 불검출~71ppm, 먹는물이 불검출~173ppm으로 나타났다. 질산성질소의 경우 먹는샘물은 불검출~2.1ppm으로 나타났고 먹는물의 경우 불검출~44.8ppm까지 나타났다. 황산이온은 먹는샘물의 경우 불검출~23ppm으로 나타났고, 먹는물의 경우 불검출~141ppm으로 나타났다.

농인의 관점에서 본 농교육의 전환 : The Deaf Centered Approach

곽정란,정운기,김경진 국립특수교육원 2004 특수교육연구 Vol.11 No.2

본 연구의 목적은 농아동을 특수교육의 대상으로 국한시키는 것에서 벗어나 농교육의 중요한 주체의 하나로서 인식하여, 그들의 요구(needs)를 이해하고 지원하기 위해 농인의 관점에서 농교육의 전환 방향을 모색해 보는데 있다. 이를 위해 첫째, 농인에 대한 사회·문화적 관점은 어떤 내용을 내포하고 있으며, 농인 스스로는 자신을 어떻게 바라보고 있는가, 둘째, 농인의 관점을 지원하기 위한 사회제도는 어떻게 변화하고 있으며, 최근 농사회의 자기권리 주장은 무엇인가, 셋째 농인의 관점에서 농교육의 전환 방향은 무엇인가를 살펴보았다. 고찰 한 결과 농(deaf)의 개념은 청각장애만을 의미하는 것이 아니라 사회·문화적 환경에 따라 다른 의미로 구성될 수 있는 것으로, 이는 농인의 언어인 수화에 대한 사회적 수용에 따라 달라지는 것을 알 수 있었다. 즉 농인에 대한 사회·문화적 관점에 기반할 때 농인은 청각장애인을 의미하는 것이 아니라 수화라는 언어를 사용하는 언어적·문화적 소수집단을 의미하였다. 이에 따라 오늘날의 사회는 수화통역제도 수화통역센타를 통해 농인의 언어적·문화적 입장을 존중하기 위해 변화하고 있으며, 농인 역시 언어적·문화적 권리를 강조하고 있는 것으로 나타났다. 농인의 관점에 입각한 농교육의 전환 방향은 첫째 농아동의 언어적·문화적 배경을 이해하고 지원해 줄 수 있는 농인 교사가 필요하며, 둘째 농인으로서의 정체성을 고려하기 위해 교육과정의 재구성이 요구될 뿐 만 아니라, 셋째 농학교는 본연의 교육적 역할을 충실히 수행함과 아울러 농인의 언어와 문화를 지지하는 문화적·언어적 공간으로서의 역할을 재정립할 필요가 있는 것으로 나타났다. The purpose of this study was find ways (1) to accept people with deaf as a main or core for the education for the deaf, themselves, being over the invisible limitation that they were positioned as subjects - being educated - only on the field, and (2) to reform education for the deaf, according to the stand of view of Deaf people, which was reflected the real needs of Deaf people should be understood and supported. To establish these, the writer investigated following issues; (1) the contents of social and cultural environment of Deaf people, (2) the transition of social approach or system to support needs of Deaf people, which were issued currently on their social and cultural environment and for the more, (3) reformation of education for the deaf that was reflect opinions from or by the deaf. The concept 'deaf' doesn't mean only hearing impairments but being positioned another additional status for the cultural and social environment. The obvious factors to produce the causes of the differences are whether social acceptance and recognition their sign language as their daily communication methods, as people use speaking language. Which means considering their social and cultural environment, we can say people with deaf rather minority who are using sign language in social than handicapped people with hearing impairments. Thus, sign language translating serves, for instance, are providing to support socal and cultural stand of the deaf and ensure appropriate communication between people who are not use sign language and use it. And people with deaf put stress on the right of using their own (sign) language nowadays. The findings of reform education ways reflected view of the culture of the deaf are as follows; First, teachers who are deaf by hisself or herself in be hired in every school for the deaf to fully-understand and support students' social and cultural background, Second, curriculum of deaf education should be restructured to adapt and increase identification as a deaf, Third, schools for the deaf perform to educate deaf more substantially and should be the resource center of sign language and deaf culture.

In this paper, We propose an improved A5 stream cipher for a GSM data security. As the conventional A5 stream cipher has been analyzed in having a weakness of the 64-bit key length, we enlarge the key length of it twice (128-bit). As a result, we analyze the random property, period and linear complexity of the output sequence. Finally, We simulate the improved algorithm by C-language.

고대격투기 판크라티온의 특성

This study is a review of the characteristics and match methods of pankration on the basis of old Greek photographs, poems, and sculptures as well as various books and theses at home and abroad. As Plato depicts, "pankration" is a fierce combat sport event of mixing the aspects of wrestling and boxing. The game started from the 33rd Olympics in 648 BC. In particular, in that kicking was mainly used in pankration, it was a game mixing today's Judo, wrestling, boxing, and taekwondo. Pankration has several different characteristics compared with modem Judo, wrestling, boxing, and taekwondo. three main traits are as follows: First, that the pure Greeks (that is, noblemen only) participated, and that naked, in the exercise and the game. Second, that a flower crown and honor were the only awards given to the winners. Namely, the ancient Greeks were more interested in spiritual honor, honorably given by gods, than in material matter. third, big diiference was that pankration was a violent match risking one's life until the opponent admitted his own loss. Pankration in a one-to-one match was very relentless but two things were prohibited as fouls, poking the opponent in the eye and biting. The skills of letting the competitor fall like wrestling and striking with fists like boxing were used a lot. The competitors were drawn, while a match was continued until one player admitted his own loss by holding up one finger (usually index finger). Pankration had two types, "kato" and "ano." Kato pankration was the match going on when one player fell on the floor, and ano pankration was the match with two players standing. Noteworthily, a winner in pankration could enjoy more pan-national fame than the winners in other events, because it was not only dangerous but demanded correct training, an unusual attitude, agility, and tough endurance. According to the development of our society, contemporary people demand more violent combat sport events. As pankration is scheduled to become an exhibition event in the 28th Athens

고려전기 庶孼에 대한 사회적 인식

이정란 영남대학교 2003 민족문화논총 Vol.28 No.-

A child-by-a-concubine(hereafter Seo-el(庶孼)) in the era of Chosun was settled and fixed as a legal and social class. So, not only the person himself, but also were his descendants tagged as Seo-el. The descendants of Seo-el, with few exceptions, maintained marriage relations with Seo-el families, and became concubines of a noble class, reproducing Seo-el class. In contrast, Seo-el in Koryo was not yet fixed as a single social class. In spite of a little level of discrimination in the process of advancing to official government service, his descendants were granted a wide range of chance to free themselves from such discriminations through a variety of ways. For those reasons, the existing studies about Seo-el have been carried out whithin the scope of Seo-el in the early Chosun. Namely, Koryo's Seo-el was dealt with as a previous history of Chosun's Seo-el, not being recognized as a single independent social class. However, such a trend of study about Seo-el was derived from the limit of study in which Seo-el was examined within the confines of the history of social status. Even if it was the case that Seoel was not fixed and grouped as a social class until the late Chosun, the study about Seoel could not be touched on with little importance if the sense of discrimination against during Koryo era was deeply rooted. Moreover, the contents and degree of the discrimination against Seoel in Chosun society was so intensive that it is almost impossible to find out any similar precedent from other countries. So, it is not reasonable to account for the case in association with the introduction of metaphysics and economic background. That is to say, it does not work to try to get the answer to the discrimination policy toward Seoel, which was so noticeable only in Chosun, on the basis of the inheritance dispute derived from the disorder of marriage system at the end of Koryo, and the introduction of Metaphysics with its emphasis on clan rules. From this point of view, the sense of discrimination against concubines and their children-Seoel-during Koryo era requires close attention. Although no significant restrictions were imposed on their official career and marriage to the point that Seoel was fixed as a social class, it could be an underlying cause of the establishment of the Chosun's unique "solid discrimination policy toward Seoel". In this thesis, it is found that there had been consistent sense of discrimination toward concubines and Seoel since the early Koryo.

The purpose of this study was to examine perspectives on coaching student teaching and identify the tasks for its reconstruction. Positivisim, inquiry, and critical theory were reviewed in terms of shedding light on the problems as well as the roles and functions of the current coaching student teaching. Although they gave us some specific strategies for the efficient coaching student teaching, they have not suggested alternatives which adequately apply to various kinds of teaching-learning situations faced by cooperating teachers and student teachers. Reflective perspective was introduced as bases for transformation of the current coaching student teaching. On the basis of reflective perspective, three strategies for reconstruction of the coaching student teaching were proposed in this study; first, reconstruction of the coaching student teaching should be based on supportive relationships with equal participation and cooperation between cooperating teacher and student teacher; second, it should be built upon equal role and relationships between cooperating teacher and student teacher; lastly, it should be developed based on dialogue and conscious reflection.

This study is about an experimental investigation was conducted to examine the feasibility of Carbon Fiber sheet(CFS), a kind of high strength fiber, for repair and reinforcement method of concrete structures. The experimental program included tests of beams different in wrapping method and amount of CFS. The beams were subjected to monotonic loading. In order to practically apply the repair and reinforcement method, further research is needed for the distrtbution, amount, and bond of CFS. In this study, an experiment was conducted for R/C beams reinforced with CFS, for various wrapping method and amounts of CFS. Experimental results showed the wrapping method increasing the bond area and amount of CFS layer caused the increase in the strength of the beams.
