This study was to provide basic data for aquatic ecosystem research using fishes. Field sampling was carried out at five selected sites of Gap Stream, and fish samples, especially for a selection of sentinel species were collected three times in June, September, and October 2007. We analyzed total length distribution of Zacco platypus in relation with the season and the sampling sites, and then compared with total body weight, condition factor (K), and age distribution of the fish. The fish population data were compared with physico-chemical water quality, obtained from the Ministry of Environment, Korea. Water quality analysis showed a significant nutrient enrichment, based on total nitrogen (TN) and total phosphorus (TP), and organic matter pollution, based on biological oxygen demand (BOD) and chemical oxygen demand (COD) in the Site 5, which is directly influenced by wastewater disposal plant (WDP). Population analysis of the sentinel species showed that the total number of individuals, age distribution, and the population size-structure were influenced by the effluents from the WDP, and that reproductive failure of young-age population were evident in Site 5. According to the relation analysis of total weight to K, the disturbed population was mainly attributed to combined effects of habitat modifications and chemical degradations. Regression analysis of K values against water quality parameters showed significant (p<0.05) positive relations with nutrient and organic matter contents. Our data suggest that the population structure using a sentinel fish species reflected the ambient water quality in the stream and that diagnosis of aquatic ecosystem health using Z. platypus population may be practical for water resource and ecosystem conservations.

본 연구는 만 2~5세 영·유아의 발달 상태를 객관적으로 평가함과 동시에 발달이 지연된 영·유아를 선별할 수 있는 발달평가도구 문항을 개발하기 위한 예비연구이다. 이를 위해 문헌고찰 및 발달관련 평가도구들을 비교 분석하여 발달지표를 선정하고, 만 2세~5세까지의 영·유아의 언어, 인지, 사회·정서발달영역을 교사관찰에 기초하여 평가할 수 있는 문항을 개발하였다. 연구대상은 대도시, 중소도시, 읍면 소재지 별로 표집 된 만 2세부터 5세까지 총 13개 유아교육기관에 다니는 435명의 영·유아들이며, 본 연구에서 최종 개발된 평가도구의 문항은 총 141문항이다. 평가도구 문항은 언어, 인지, 사회·정서발달영역별로 영·유아의 행동과 언어를 중심으로 교사가 관찰하고, 관찰하기 어려운 문항에 대해서는 단서와 kit를 제시하여 평가할 수 있도록 구성하였다. 개발된 평가도구 문항의 적절성을 알아보기 위하여 내용 타당도와 내적 신뢰도를 살펴본 결과 비교적 양호한 것으로 나타났다. This was a preliminary study to construct a developmental rating scale for understanding children's objective developmental levels and screening developmental disabilities. For this purpose, a developmental indicator was selected by a literature review and comparative analysis of related developmental assessment tests. An assessment scale based on teacher's observations to measure language, recognition, and social-emotional developmental areas was developed. The subjects were 435 young children aged 2 to 5 who lived in both urban and rural areas. A trial test consisted of 141 assessment items in the language, recognition, and social-emotional developmental domains. The developmental scale was evaluated by teachers who observed children's behavior and language, and used clues and kits. Tests on validity and reliability for confirming the appropriateness of the developed assessment scale showed that content was relatively valid and internally consistent.

동화(同化)와 이화(異化)의 문화정치, 1925년의 음악계

김은영 ( Kim Eun Young ),신혜승 ( Shin Hye Seung ) 이화여자대학교 음악연구소 2021 이화음악논집 Vol.25 No.4

본고는 1920년대 문화통치기의 음악사회를 고찰하였다. 3.1운동 이후 일제는 식민통치의 방식을 무단통치에서 문화정치로 바꾸었고 조선어 신문의 발행을 허용했다. 민족주의자들은 신문 및 잡지를 정치적 담론의 공간으로 활용하는 한편, 일제에 의해 허용된 범위 내에서 문화운동을 전개하였다. 1920년대의 문화운동은 특히 일본 유학생 출신의 지식인들이 주도하였고 서구 근대예술을 모델로 하는 신문화운동의 전개와 사회주의의 영향을 받은 예술 활동을 특징으로 하고 있다. 식민지 지식인들의 문화운동에 김영환, 홍난파, 윤심덕, 한기주 등 동경 유학파 출신 음악가들의 참여도 있었다. 본고에서는 1925년의 음악회를 중심으로 1920년대의 음악사회를 고찰하였다. 1925년은 최초의 음악전문잡지 『음악계』가 출판된 해로, 홍난파는 전문음악회를 표방하였다. 그가 생각하는 “음악회다운 음악회”는 동정음악회나 자선음악회와 같은 사회구제 성격의 음악회가 아닌 ‘음악을 위한 음악회’, 다시 말해 서구음악을 주요 레퍼토리로 하는 음악회였다. 그러나 1925년의 대홍수로 한반도는 엄청난 피해를 입었고 이 사건으로 일제의 동화정책의 허구와 민족차별의 실체가 드러나게 된다. 수해구제를 위한 음악회는 경성을 넘어 전국에 걸쳐 개최되었으며 당국은 수해구제를 명시하는 음악회를 금지함으로써 음악회는 민족 공동체의 일체감을 형성하는 중요한 매개체가 된다. 1920년대 음악회의 또 다른 양상으로 음악무도의 유행이 있었다. 천도교 소년회에서 시작된 어린이/소년운동은 사회주의의 영향으로 건강한 신체의 단련을 표방했고 음악무도는 이 시대를 특징짓는 하나의 음악현상이 되었다. 음악무도의 유행은 1925년의 음악회에도 반영되어 당대의 대표적 음악가들이 참여한 가운데 어린이 및 소년회, 각 교회의 주일학교, 유치원 등에서 주최하는 경우가 많았다. 1925년의 음악회를 통해 문화통치기 일제의 동화주의 정책의 이면에는 배제와 차별의 이화(異化)가 존재했음을 확인할 수 있다. 일제가 문화통치를 위해 노린 것은 민족주의 내부의 분열과 이를 통한 친일파의 양성에 있었고 음악계도 문화통치의 영향에서 벗어날 수 없었다. This paper examines the music society under the cultural rule during 1920s. After the March 1st Movement, the Japanese changed the way of colonial rule to cultural politics and allowed the publication of Korean newspapers. Nationalists used newspapers and magazines as spaces for political discourse, while carrying out cultural movements within the limits allowed by the Japanese. The cultural movement of the 1920s was especially led by intellectuals who studied in Japan, and was characterized by the development of a new cultural movement modeled on Western modern art and artistic activities influenced by socialism. Musicians from Tokyo, such as Kim Young-hwan, Hong Nan-pa, Yoon Shim-deok, and Han Ki-joo, also participated in the cultural movement led by colonial intellectuals. This paper examines the music society during 1920s, mainly focusing on music concerts in 1925. 1925 was the year when the first music magazine ‘The Musical World (Um-Ak-Gye)’ was published, and Hong Nan-pa advocated a professional music concert. He thought of “concert-like concerts” as “concerts for music,” in other words, a concert with Western music as its main repertoire, not a concert of social relief such as sympathetic concerts or charity concerts. However, it was also the year when the great flood in 1925 that caused tremendous damage to the Korean Peninsula, revealing unsubstantiality of imperialism’s assimilation policy and national discrimination of Japan. Concerts about flood relief took place across the country beyond Gyeongseong, and by banning concerts specifying flood relief, concerts become an important medium for forming a sense of unity in the national community. There was a trend of music and dance, as another aspect of music concerts during 1920s. The children’s/boys movement, which began at the Cheondogyo Juvenile Association, advocated the training of a healthy body, and music and dance became a musical phenomenon characterizing this era. Music concerts in 1925 were hosted by children’s and juvenile associations, Sunday schools of each church, and kindergartens. The participation of all musicians active at the time stands out. Through the concert in 1925, it was confirmed that there was a politics of exclusion and discrimination behind the assimilationist policy of the Japanese colonial rule. What the Japanese imperialism aimed at for cultural rule was the division within nationalism and was to make pro- Japanese group through it, and the music community could not escape from the influence of cultural rule. History proves this.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

This study was planned to suggest countermeasure of nutrition education by investigating adolescents, dietary behavior, food weight, and acknowledgement of food calories. 210 middle school boys were selected and asked to fill out the questionnaire. The subjects were divided by nutrition education experience; 1st grade who received nutrition session and 3rd grade who divided subjects. In terms of acknowledgement of food calories subjects nutrition education experience had more recognition for calories than the other group(p<0.01). When one bowl of rice, a potato, a bowel of kimchi and a carrot were asked. However recognition for meats, fishes and eggs were not different between two groups. Among milk and dairy foods the educated group showed high recognition both calories and weight of a piece of cheese than the other(p<0.05). The educated group showed better recognition for calories and weight of tea-spoon of butter, a tea spoon of oil and a tea-spoon of mayonaise, compared to the other group(p<0.01, p<0.05, p<0.05). Also the educated group showed better recognition for calories and weight of a packet of shrimp snack than the other group. The results of this study suggest that nutrition education improved the recognition of calories and weights of foods in study subjects. Also, the number of foods recognized for their calories and weights was higher among subjects who received nutrition education. These results will influence the choice the food by adolescents. Also the nutrition education are thought to be more effective by using photographs or food models, not just by lectures on theories.

김은영,권민석,김신,정태성 大韓小兒齒科學會 2012 大韓小兒齒科學會誌 Vol.39 No.1

The concept of resin infiltration which was born in an innovative philosophy to arrest the incipient caries. However, the structural changes of resin infiltrated lesions have not yet explained completely. The liquid resin might contribute not only to maximizing the penetration but to deteriorating physical stability. This study was performed to examine some physical and histological features of resin infiltrated incipient carious lesions. With the specimen of resin infiltrated lesions, microhardness by nanoindentation in depth profile, morphology of resin tags were revealed after HCl dissolution, and degree of microleakage were assessed. The percentage of microhardness of surface layer and lesion body of untreated specimen to sound enamel was 64.6% and 24.6% respectively, while that of resin-infiltrated lesions was 72.1%, showing significant difference (p<0.05). The resin tags observed under SEM had relatively homogeneous length of 433(282~501) ㎛ on the average. Among 20 specimens for microleakage assessment, 13 specimens showed no leakage while 5 and 2 showed leakage into outer and inner half of lesion respectively. It was thought the infiltrant resin penetrates deeply and homogeneously into lesion body and improves its hardness with relatively good physical stability. 본 연구는 infiltrant resin을 침투시킨 초기 우식 병소의 특성을 평가하기 위해 법랑질의 깊이에 따른 경도를 측정하고, 병 소 내로의 레진 침투양상을 분석하며, 미세누출 정도를 관찰하여 다음의 결과를 얻었다. 건전 법랑질에 대한 초기 우식 법랑질의 경도 백분율은 표층(5~40 ㎛) 64.6%, 병소본체(60~350 ㎛) 24.6%였으며, infiltrant resin을 침투시킨 병소의 경도 백분율은 72.1%로 나타났다. 5~350 ㎛의 전 깊이에서, infiltrant resin을 침투시 킨 병소는 비처치 우식 병소보다 경도가 유의하게 높았지만 정상 법랑질에 비해서는 경도가 유의하게 낮았다(p<0.05). FESEM 관찰 결과 탈회된 법랑질 내부로 비교적 균일하게 침투한 레진 테그가 관찰되었으며, 침투깊이는 433 ㎛(282-501)로 측정되었다. 열순환 처리 후 13개의 치아에서 미세누출이 관찰되지 않았고, 5개에서 병소 외측 절반, 2개에서 병소 내측 절 반까지 미세누출이 관찰되었다.

In this study, we prepared biodegradable polysaccharide films with pullulan, κ-carrageenan, curdlan and chitosan and measured physical properties and antibacterial activity All of polysaccharide films showed the high biodegradability but antibacterial activity on bacteria was only observed at chitosan film. The permeability of the gas(O₂and C0₂) of polysaccharide films besides chitosan film showed 50∼100 times lower than polyethylene(PE) film. Therefore, we prepared two film types to give low gas permeability and antibacterial property at polysaccharide film : one type was the physically mixed film(k-carrageenan +chitosan) and other type was the chitosan coated κ-carrageenan film. Chitosan coated κ-carrageenan film showed low gas permeability and antibacterial activity.
