Cadmium, a major aquatic pollutant in many parts of the world, is toxic and readily accumulated in aquatic organisms. It mainly exists in water as complexes with organic ligands such as dissolved organic carbon and this complexation is known to have effects on the aquatic toxicities. In this study, acute toxicity, histology, and bioaccumulation were studied to evaluate effects of humic acid on cadmium toxicity and bioavailability to fish using Oryzias latipes and Cyprinus carpio. 96h-LC50 of cadmium was 6.38 ㎎/L using Oryzias latipes. However, the mortality showed the dose-dependent decrease when humic acid was added to the test solution. When fish were exposed to 5㎎/L of cadmium, histological changes in the exposed organs(caudal fins, gills, kidney, liver, and gut) of Cyprinus carpio were decreased by humic acid, especially in kidney and liver. Bioaccumulation of cadmium also decreased by treatment of humic acid. It seems that the formation of complexes between cadmium and humic acid may decrease bioavailability of cadmium to fish, and thus reduce the toxic effects of cadmium.

Yeun Sang-kyu was a Buddhist painter, known as “Mother of Buddha Image Paintings(佛母)” who was inherited by Gyeongsan School and kept the tradition intact till 1930. His Buddhist Image paintings are handed down from the mid-19th century on and his painting styles and lineages are well known and even the painting materials he used are cleary identified. So much he is recognized as unique and distinctive. During the late Joseon Period, the Buddhist paintings in the temples are provided and enshrined by the local monk painters and the large temples have accordingly housed a group of monk painters in their own territories. This monk painters were eventually clustered with the painter groups. “The Gyeonseong or the Gyeongsan School” was one of the most active painter groups who got together in Seoul and Gyeonggi area. Yeun`s Buddhist paintings so far extant in terms of iconography or drawing skills reveals inheritances of various styles of the previous traditions; early and late 18th century, or early and late 19th century styles are included. Moreover, on top of those mixture of traditions, he added a new trend of paintings based on the up-coming new cultures. Even western painting skills of shading were imbued with his many a Buddhist paintings and his creative new form of icons and compositions are keenly felt the influences of his direct master Eungseok`s style. His new Buddhist depictions seem to be popular among the connoisseurs and the collectors so that his art objects are spread out through the country. He tried to explore the new experiments with the visual effects, the painting materials and even utilizing of the folk painting subjects. The “Samse-bul-do(三世佛圖)” of Pyochung temple is an example of the modern skills of paintings, quite differed to traditional ones; applying the geometric shape of circles in the screen, newly alloting the Bodhisattvas and the protective figures, reconfiguring the Buddha images, sectional division of the canvas, etc. Likewise, Yeun`s style changes in his extant paintings show us his creativity along with the modern tranformation of Korean Buddhism. And his legacy is handed down to Manbong, who is one of descents of Yeun and connected to today`s Buddhist painting traditions.

본 연구에서는 개사를 통한 노래부르기가 정신지체아동의 수용과 표현어휘력 신장에 미치는 효과를 알아보고자 하였다. 본 연구대상은 부산시에 소재하는 J초등학교 특수학급에 재학 중인 정신지체아동 2명으로 선정하였다. 13개의 동요 등을 개사하여 72개의 표적어휘를 선정하였고, 개사를 통한 노래부르기는 10주에 걸쳐 주 4회씩 총 40회기동안 실시하였으며 매회기는 40분간 실시하였다. 한국표준수용어휘력검사를 이용하여 사전검사와 사후검사에서 어휘력 검사를 각각 2회 실시하였다. 본 연구에서는 개사를 통한 노래부르기가 정신지체 아동의 수용어휘와 표현어휘 신장에 긍정적인 영향을 미쳤음을 제시하였다. 특히 동물과 식물명, 그리고 일반사물, 가정도구, 가정, 사회생활, 여가생활 등과 관련된 명사 어휘의 수용과 표현이 높아지고 동사와 형용사에 대한 수용어휘력도 향상되었다. Mental retardation refers to substantial limitations such as mental intelligibilities and social interaction in present functioning. Especially, language abilities are basic social skill to identity and interact with themselves and others in the society as human beings. Unfortunately, the children with mental retardation are usually exposed in language difficulties. Vocabulary is a fundamental tool to lead smooth language development. The purpose of this study was to illustrate the effects of singing with changed words of songs to develop vocabulary abilities for children with mental retardation. Two children, 10.6(MA5.7) and 11.0(MA7.2) years old, with mental retardation were participated for this study. Thirteen sings were selected, and the words of the songs were changed based on seventy two target vocabularies. Pre- and post-test with Korean Standard Vocabulary Test were utilized to verify the effective of the singing to improve vocabulary ability for forty sessions. Each sessions was for forty minutes. The results of this study were that: (a) the singing strategy was effective to improve the receptive vocabulary ability; and (b) the singing strategy was effective to improve expressive vocabulary ability for children with mental retardation. Therefore, this study concluded that the singing is effective to improve vocabulary ability for mental retardation.

Pamela 소고

최상규 공주교육대학교 초등연구원 1969 公州敎大論叢 Vol.6 No.-

Richardson's PAMELA is the first true English novel in view of the fact that it changed the stream of novel-form in English literature, by sustituting an unique story-telling device which, in epistolarly form, enabled him of presenting the psychological implications of character directly and dramatically to the readers receding himself invisible, for the fantastic and insubstantial romance or so superficial and shallow novel, as of Defoe. His aims in the novel were to edify and amuse the reader taking up a series of conflict and struggle between seduction and resistance, that is, between Mr. B. and Pamela. And his main protest was in the name of religion and morality, and his concern was to improve moral through a thrilling sexual narrative. In defiance of such structural and technical defects as the descrepancy between the promises of the title and the actuality of the text, limitation of Mr. B. as a character, shift in the characterization of Pamela from the vital, witty girl of Part I to the almost allegorical figure o£ Part II, and difficulties of an epistolary style in which there is only one correspondent, who therefore must constantly advertise her own virtues, etc…,it was a great success. And the most vital element in the work and, at the same time, the thing that made it so spectacularly successful is its confused but angry concern with social injustice rather than its psychological realism.

재량적 회계변경의 정보효과

최성규, 서대석 영남대학교 사회과학연구소 2000 社會科學硏究 Vol.20 No.1

본 연구는 재량적 회계변경에 대한 자본시장의 반응을 검증하기 위한 5개의 가설을 제시하고 이를 실증하였다. 이 가설들의 기본 논리는 대부분의 재량적 회계변경이 회계정보의 유용성을 증가시키기보다는 기업의 재무상태와 경영성과를 유리하게 보이기 위한 경영자의 기회주의적 유인이 더 많이 작용했을 것이라는 데 초점을 맞추고 있다. 가설을 검증하기 위하여 재량적발생에 대한 반응계수를 살펴보았으며, 검증결과, 가설과 일관된 결과를 얻을 수 있었다.

장애아동의 어휘지도를 위한 일반아동의 기초어휘 난이도 분석

최성규 국립특수교육원 1999 특수교육연구 Vol.6 No.-

언어의 사용능력은 어휘에 대한 정확한 이해와 사용 어휘의 양에 영향을 받기 때문에 어휘지도의 중요성이 강조된다. 본 연구의 목적은 장애아동의 체계적인 어휘지도를 위하여 일반아동을 대상으로 기초어휘의 난이도를 분석하는 것이었다. 주관식과 객관식 방법을 혼용한 절충식 방법으로 선정한 허위를 100개 문항에 각 다섯 개의 어휘를 배분하여 500개의 어휘가 선정되었다. 선정된 어휘의 난이도는 장애아동의 특성을 고려하여 각 어휘에 대한 난이도를 최소화하여 밀도 높은 어휘 문항으로 구성하였다. 각 조별로 100개의 문항으로 배정하여 모두 500어휘를 전국의 병설 유치원과 초등학교에 재학중인 939명의 아동을 배상으로 검사하여 난이도를 분석하였다. 연구결과를 기초로 각조별 어휘를 난이도에 따라 배분하여 각조별 신뢰도가 상호간에 r2=.90이상이 되도록 조정하였다. 그리고 기초어휘의 정답수를 기초로 평균과 표준편차를 산출하여 검사결과에 대한 어휘 습득 백분율(점수환산표)을 제시하였다. 본 연구에서 제시된 기초어휘는 장애아의 어휘력 습득을 객관적으로 산출하는 검사도구로 활용이 가능하기 때문에 장애아의 어휘력 신장을 위한 개별화교육 프로그램 작성에 중요한 참고 자료로 활용이 가능할 것이다. 그러나 본 연구는 기초어휘의 수용에 관한 사항에 한정하였으므로 기초어휘의 표현과 기초어휘에 대한 문자 언어의 이해력 등과 같은 연구가 지속적으로 이루어져야 할 것이다. Language is an important ability and tool in human societies, however, there is no single way in which learn to communicate. Although each child follows an individual developmental pattern, language development requires basic vocabulary ability. Vocabulary ability related with amount and quality on vocabulary is a core in language development. The purpose of this study was to investigate children's difficult degree on basic vocabulary ability to teach vocabulary for children with disabilities. The vocabulary was selected mixed method which is combined with subjective and objective method in vocabulary selection methods. One hundred vocabulary items which include five vocabulary on one plate. Therefore five hundred vocabularies were selected. The subjects were 939 kindergarten and elementary children. After test the difficult degrees in each items were manipulate to keep validity to use regardless specific items which means the items have high validity as .90. Also, score table based on mean and standard deviation were analyzed. This research suggested that (1) this study in limited on comprehensive ability on vocabulary, therefore productive ability on vocabulary needs for following study; and (b) written language ability based on basic vocabulary is needed for next study.
