최재훈,권선화,이상원,남상해,최상도,박석규 한국식품저장유통학회 ( 구 한국농산물저장유통학회 ) 2003 한국식품저장유통학회지 Vol.10 No.3
전통메주의 표면에서 발행하는 야생곰팡이 착생, 유해곰팡이에 대한 mycotoxin 생성 및 메주 표면의 과도한 건조 등을 해결하기 위하여 메주 외층에 Aspergillus oryzae로 만든 쌀 종국(0.3%, w/w)을 혼합시킨 증자 검정콩으로 얇게 코팅한 후, 25℃, 상대습도 80%에서 14일간 발효시킨 캡슐형 메주를 개발하였다. 캡슐형 메주의 표면에서 야생곰팡이의 오염은 발견되지 않았으나, 대조구 메주는 12일 이후에 푸른곰팡이가 많이 관찰되었다. 메주의 수분 함량은 평균 32.7%로서 34.7~29.4%의 범위를 나타내었다. 적정산도는 캡슐형 메주가 대조구 메주보다 높게 나타났으며, 대두 캡슐형 메주와 검정콩 캡슐형 메주는 비슷하게 나타났다. 유리당의 함량은 검정콩 캡슐형 메주가 123.98㎎%로 대조구 메주 15.02㎎%와 대두 캡슐형 메주 59.85㎎%보다 각각 10배, 2.1배, 높게 나타났다. 아미노산성 질소의 함량은 대조구 메주에서 147.00㎎%였으며, 검정콩 캡슐형 메주는 255.50㎎%로서 대두 캡슐형 메주 187.25㎎%보다 약 1.37배 높은 함량을 나타내었다. 총 유기산의 함량은 캡슐형 메주(대두 119.98㎎%, 검정콩 95.94㎎%)가 대조두 메주(26.44㎎%)보다 함량이 높게 나타났으며, 캡슐화에 따라 lactic acid와 malic acid 가 가장 큰 변화를 나타내었다. 색차계 색도는 검정콩 캡슐형 메주가 대두 캡슐형 메주보다 명도값(L)이 크게 나타났으며 지방산 조성은 메주의 종류에 따라 큰 차이를 나타내지 않았다. 총 유리 아미노산의 함량은 검정콩 캡슐형 메주(1039.70㎎%)가 대두 캡슐형 메주 (556.07㎎%)와 대조구 메주(236.45㎎%) 비하여 각각 2.4배, 4.4배 높았다. In order to improve some problems such as contamination of undersirable mold, mycotoxin production and excessive drying on the surface of traditional meju, we developed a capsule type-meju(CM) coated with steamed black bean and Aspergillus oryzae - rice koji(0.3%, w/w) mixture to surface of traditional meju and fermented at 25℃ for 14 days under 80% relative hunmidity. Contamination of undersirable mold on the surface of CM was not detected within 2 weeks and some genus Penicillium molds on control meju without koji were found naturally after 12 days of fermentation. The moisture content of meju was showed to be in the range of 34.7 - 29.4% being 32.7(w/w) of mean value. Titratable acidities in CMs prepared with black bean(BCM) and soybean(SCM) were much higher than that in control meju, and BCM was similar to SCM. Free sugar content in BCM(123.98 ㎎%) was 10 times and 2.1 times higher than that in control meju(15.02 ㎎%) and SCM(59.85㎎%), respectively. Amino type nitrogen content in control meju was 147.00 ㎎% and its content in BCM(255.50㎎%) was 1.37 times higher than that in SCM(187.25 mg%). Total organic acid content in BCM(95.98㎎%) and SCM(119.98㎎%) were much higher than that in control meju(26.44 ㎎%), and then latic and malic acid contents were markedly changed according to capsulation of meju. Lightness value(l) of Hunter color index was much higher in BCM than in SCM. Fatty acid composition of CM was not different as compared to control meju. Total free amino acid content in BCM(1039.70 ㎎%) was 4.4 times and 2.4 times higher than that in control meju(236.45 ㎎%) and SCM(556.07 ㎎%), respectively.

예운상규는 경산화파의 화맥 안에서 전승되는 불화의 형식으로 작업에 임했으며 또한 전승시킨 불모(佛母)이다. 19세기 중반부터 전하고 있는 그의 불화는 1930년에까지 이르고 있다. 경산화파는 불모들의 계보 가운데 비교적 화맥이 잘 밝혀져 있고 전해지는 불화의 소재가 어느 정도 파악되어 그 특징을 살펴 볼 수 있다. 조선 후기에는 대부분 사찰 불화의 수요가 그 지방 승려들에 의해 충족되었고 이에 따라서 다양한 승려가 많이 모이는 대사찰 중심으로 배출된 화승들은 자신의 출신 사찰을 중심으로 인근지역 안에서 활동함으로써 지역에 따른 화사(畵師) 집단이 형성되었다. 이와 같은 화사 집단 가운데 서울·경기지역에서 활동한 화사들을 경성화파 또는 경산 화파라 부른다. 예운 불화는 조선 후기 서울·경기지역 불화와 같이 시대와 양식에 따라 분류할 수 있다. 18세기 초와 18세기 말~19세기 초, 19세기 말로 분류하는데, 현존하는 근대기 예 운의 불화는 도상과 표현기법에 있어 다양한 경향의 불화 제작과 새로운 문물의 유입을 통한 신경향의 불화를 남기고 있다. 근대기 예운의 불화의 상당수는 서양화의 명암법을 도입하고 있으며 스승인 응석 의 맥을 이어 새로운 도상과 구도법을 창안하였다. 서양화의 명암법을 적용해 그린 그의 불화들은 당시 후원자들로부터 상당히 인기가 있었던 듯하며 현재 전국에서 작품이 남 아 전한다. 예운은 전통 도상을 기반으로 일반 회화나 민화와 같은 각종의 회화자료, 그 리고 새로 유입된 외국의 인쇄물 등의 시각적 체험과 자료들, 당시의 풍물·풍속 등 새 로운 요소들을 수용하기 시작하는 등 끊임없이 변화를 주기위한 시도들을 하였다. 표충사 <삼세불도>처럼 원과 같은 기하학적 도형을 사용해 화면에 집중감을 주면 서도 때로는 수많은 권속들을 적절히 분류하고 구획하여 시각적 효과를 살린 불화들과 기존 불화의 구성요소들을 새롭게 재구성하거나 일부를 첨삭하는 등의 방법으로 주제를 강조한 불화들을 제작하였다. 화면분할식 불화와 함께 새로운 불화를 시도하려 했던 그의 창작 의도가 보다 명확하였다고 할 수 있다. 이와 같이 근대기 예운 불화의 의미는 화사의 창의성이 발현된 점이라고 할 수 있으며 이후 새롭게 만봉에 의해 전승이 되고 현재에까지 이어짐으로 해서 역사적 변천을 살필 수 있다는 점이 또한 중요하게 평가될 수 있는 것이다. 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.

Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

Thomas Wolfe’s novels make altogether one impression that he was a novelist who had been struggling solely by himself to gain the battle grappling with the whole system of his own ideas and experiences. He had always explained himself in each work whatever the title of the novel should be, and written a single long story about himself. Consequently, he gained ill fame, not only that he had written an autobi-ography and could have done nothing more, but also that he had been ignorant of the authodoxical techni-que and requisite form of a novel. But the extraordinary heap of his experiences and memories was the only constituent of his lost world that he could recapture, and it was not merely the material and resource for his story. It was rather a medium of the flight into the cosmos of eternal time, which enabled him to cognize the world, the core of being, the entity of the whole universe. This is the very reason why his antobiograph ical self-pursuit surpasses romantic self-justification or formless absurdity of spate-writing.

Choi,Seong-Kyu,Yun,Kyeong-Won,Chon,Sang-Uk,Seo,Young-Nam,Seo,Kyoung-sun,Kwon,Byung-Sun 한국자원식물학회 2003 Plant Resources Vol.6 No.3
This study was conducted to produce effectively more leaves of Angelica acutiloba through year-round production system by using various mulching materials and polyethylene(PE) tunnel. Soil temperature by covering treatment was higher in PE mulching and PE tunnel than in rice straw mulching, especially showing the highest temperature in PE tunnel from April through May. Water content of soil was higher in PE mulching than in non-mulching. Leaf production of Angelica acutiloba through year-round production showed the highest in PE tunnel and root production in PE mulching. These results suggest that leaf production of Angelica acutiloba can be maximized through PE tunnel cultivation system.
