속성수로 활용되는 버드나무속 식물들은 생식기관과 영양기관의 성장 시기가 달라 형태적 특성 평가를 위해 수년간의 조사 기간이 요구된다. 따라서 바이오매스 우수 버드나무속 교잡종 육성의 성공 여부를 조기 판별하기 위한 식별 기술이 필요하다. DNA 마커는 식물의 생장단계와 관련 없이 탐색할 수 있으며 환경에 영향을 받지 않는 장점이 있다. 식물의 계통 분류 시 주로 사용되는 엽록체 DNA는 유전자 염기서열의 변이가 비교적 크지 않은 장점이 있으나 대부분의 활엽수에서 모계를 통해 유전되는 특징이 있다. 하지만 종간 교잡종의 식별은 각각의 부모종과 구분할 수 있어야 하므로 본 연구는 엽록체 DNA가 아닌 핵 DNA를 대상으로 분석하였다. 본 연구의 목적은 호랑버들을 암나무로 갯버들을 수나무로 인공교배하여 육성된 종간 교잡종을 식별하는 핵 DNA 마커를 탐색하는 것이다. 이를 위해 버드나무속에서 개발된 총 35개의 nSSR (nuclear Simple Sequence Repeat) 마커를 대상으로 호랑버들과 갯버들, 종간 교잡종의 식별 가능성을 평가하였다. 분석 결과 호랑버들과 갯버들, 종간 교잡종 간 차이를 나타내는 2개의 핵 DNA 마커를 선발하였다. 따라서 선발된 핵 DNA 마커를 활용하여 호랑버들과 갯버들, 종간 교잡종의 조기 식별에 활용이 가능할 것으로 사료된다.

고병원성조류인플루엔자는 2003년 12월 10일 충북 음성군에서 최초 발생한 이후 2004년 3월 20일 경기 양주시를 마지막으로 총 19건이 발생되었으며, 지난 5월 29일 경남 양산지역을 마지막으로 이동제한이 전국적으로 해제되었다. 정부에서는 2004년 9월 21일부로 국제수역사무국(OIE)에 국내종식상황을 통보하였고 이에 일본에서는 국내산 가금육의 수입중단조치를 10월 13일에 해제하기에 이르렀다. 그러나 6월 16일 인도네시아를 기점으로 베트남(6.29), 태국(7.6), 중국(7.6) 등 총 15개에서 재발$\cdot$확산되고 있으며, 태국에서는 이종간의 전파로 호랑이가 30여마리가 조류인플루엔자로 폐사하고 유사증상을 보이는 호랑이 30마리를 살처분하기(10월 21일)에 이르렀다.

'10년이면 강산이 변한다'는 말은 이제 호랑이 담배피던 시절 얘기일 뿐이다. 하루가 멀게 바뀌는 트렌드의 물결 속에서 제과업계는 어떻게 변해가고 있을까. 유난히 힘겨웠던 지난해 우리업계가 걸오온 발자취를 더듬으면서 하반기부터 슬슬 다시 좋아진다는 올해의 희망을 예감해본다. 2003년부터 2004년까지 쭉 훑어본 제과업계를 들여다보자.

I tried to understand a folk tale "The half-boy" in terms of analytical psychology. In the story, a lady without children prayed to the Buddha. The white old man came and gave three fishes, but the cat ate half of it. So, she ate two and a half. She gave birth to two perfect sons. The third son had one arm, one leg, and one eye. They grew well. Brothers went to take the civil service examinations, and the half-boy followed. But two brothers did not like the half-boy coming along. So, brothers tied the half-boy to the rocks and trees, and he picked them up with force and gave them down to the yard of the house. And the half-boy followed his brothers again, and brothers tied him with kudzu and put him in front of the tiger. The half-boy won the tiger by betting with cutting kudzu. The half-boy stripped off the tiger's skin. The host coveted the tiger skin and they played with janggi. The half-boy won the game and was permitted to take host's daughter. The half-boy went with a string, a drum, a flea, and a bedbug. He teased host's people with these. The half-boy brought a virgin and lived well. "The Half-Boy" folktale is an old story spread throughout the country. There are similar stories in India and Africa. Unilateral figures are universally distributed archetypal images. In numerous cultures gods and spirits are being portrayed as unilateral figures. In the creation mythology, half-figure beings have immortality. In Indonesian and African folk tales, the half-born boy goes to heaven and merges with its half and becomes perfect. Some of one-sided spirits are harmful to humans but some of one-sided birds, chickens, and spirits are helpful to people. Sometimes half being is a cultural hero who steals grain from heaven or gets some advice how to use bamboo. There are stories that half body becomes a whole body afterwards. But in this folktale and most of the similar folktales, half-figure does not change and maintains half-figure to the end. And as a half-figure he does various great things and marries a virgin. The half-boy symbolizes a psychic experience born in the unconscious. The unconscious contents may seem strange and weird at first and the collective consciousness does not want to accept them. But the unconscious exerts greater power and brings vitality and creativity to consciousness. This folk tale seems to have compensated for the stubborn collective consciousness of our society, which was a Confucian class society. It also allows people to change their attitude toward disabled people and recognize strengths and creativity of the handicapped.

Tigers are the large cats with prominent, black or brawn, stripes. They are common in jungles of India and Java, but range as far as the snowy, forested mountains of Siberia. Legal and illegal killing(over-hunting, poaching for skin, and also its bones, f

Genetic variation of Ilex cornuta Lindley et Paxton was examined by sequence analyses of ITS for 65 individuals from Korea and China. The length of ITS 1 ranged from 253 to 259 bp. The 5.8S was 159 bp and ITS2 was observed to be 231 bp. A total of 8 different ITS types (Single Nucleotide Polymorphism haplotypes), which showed the difference of 1 - 6 bp, were detected from 65 individuals. The sequence polymorphisms of ITS appeared at 9 different sites. All of four individuals collected at Daejeong-eup in Jeju-do exhibited different types, but all individuals from Naju-si and Muan-gun in Jeollanam-do were identical. The variation of ITS was higher in Jeju-do population than in inland population. Since I. cornuta contains various types of ITS sequences, ITS analyses will provide important information on genetic diversity and conservation of this species.

This study aims to determine the perspectives of pre-service elementary school teachers on the science curriculum in the fourth industrial revolution era. In this study, 128 pre-service elementary school teachers were asked to express their perspectives on the Saber-toothed Tiger Curriculum through photovoice activities. The resulting images were classified into three types: conservative, progressive, and radical perspectives. The number of both conservative and progressive perspectives was similar and high, whereas the number of radical perspectives was l ow. Those who had conservative perspectives on the Saber-toothed Tiger curriculum regarded "Inquiry" as the basis of the science curriculum, which should be maintained regardless of the time period and environment. Similarly, older teachers believed that this curriculum was based on eternal truth, which should be protected. Those who showed progressive perspectives on the Saber-toothed Tiger curriculum regarded a progressive person as someone succeeding to the blood of "New fist," and they showed positive attitudes toward AI-based education such as coding and meta-verse, regarding these practices as part of the teaching and learning method that could replace the existing inquiry-based education. Those who showed radical perspectives on the Saber-toothed Tiger Curriculum assumed critical attitudes toward the rapidly changing political circumstances of science education and criticized conflicts between different social classes formed through progressive curriculum. Based on these results, this study found that pre-service elementary school teachers needed to consider the science curriculum from several different perspectives rather than just one.
