본 연구는 초등학교 교사들이 2022 개정 교육과정에 관해 어떻게 인식하고 있으며 현장 적용 과정에서 무엇을 경험하는지 탐구하려는 목적에 따라 수행되었다. 연구 목적을 효과적으로 달성하기 위하여 전남 지역에 근무하는 초등학교 교사 11명을 대상으로 FGI를 수행하고 그 내용을 질적 분석하였다. 연구 결과 첫째, 교사들은 교육과정 총론에서 주요하게 제시된 용어인 자율에 관해 공감하고 그 필요성을 인정하는 동시에 개념적 혼란과 불안을 느끼고 있었다. 둘째, 디지털 교육 측면에서 교사들은 개인적 배경과 지역적 맥락에 따른 큰 격차를 경험하고 있었다. 셋째, 교육과정의 개정과 적용과는 별개로 교사들은 나름대로 개인적인 수업 전문성을 갖추어 나가고 있었다. 넷째, 평가에서는 개정 이전의 교육과정과 큰 차별점이 나타나지 않았다. 이러한 연구 결과를 토대로 교육과정 개발과 운영 측면에서 시사점을 제언하였다. This study aimed to explore how elementary school teachers perceive the 2022 revised national curriculum and what they experience during its implementation in the field. To achieve this objective, a Focus Group Interview (FGI) was conducted with 11 elementary school teachers working in the Jeonnam region, and the data were analyzed qualitatively. The results of the study are as follows: First, while teachers sympathized with the concept of "autonomy," a key term presented in the general guideline of the curriculum, and acknowledged its necessity, they also expressed conceptual confusion and anxiety. Second, in the context of digital education, teachers experienced significant disparities due to personal backgrounds and regional contexts. Third, regardless of the curriculum revision and its implementation, teachers were individually developing their own teaching expertise. Fourth, there were no significant differences in assessment compared to previous curricula. Based on these findings, implications were suggested for curriculum development and implementation.

조재성,Jo, Jai Seong 충남대학교 농업과학연구소 1975 Korean Journal of Agricultural Science Vol.2 No.2

최근 새로 육성(育成)된 Indica친수도품종(親水稻品種)/계통(系統)의 파종기이동(播種期移動)에 따르는 출종기(出種期)의 생태적변이(生態的變異)를 구명(求明)하기 위하여 21개(個) Indica친수도품종(親水稻品種)/계통(系統)과 대비품종(對比品種)으로 13개(個) Japonica 품종(品種)을 4월(月) 1일(日)부터 10일(日) 간격(間隔)으로 6회파종(回播種)하고 한편으로 단일처리구(短日處理區)와 고온처리구(高溫處理區)를 설치(設置)하여 각품종(各品種)/계통(系統)의 출종기(出種期)를 조사분석(調査分析)하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1) Japonica 품종(品種)은 물론 Indica친품종(親品種)에서도 파종기(播種期)가 늦어짐에 따라 출수(出穗)까지의 일수(日數)는 거의 직선적(直線的)인 단축(短縮)을 보였다. 2) Japonica 수도품종군(水稻品種群)에서는 조생종(早生種)은 고온(高溫)에 의한 출수기(出穗期)의 단축효과(短縮效果)가 컷으나 중만생종에서는 약간의 단축효과(短縮效果)를 보였거나 혹은 약간 늦어 졌는데 Indica친수도품종(親水稻品種)/계통상(系統詳)에서는 대체로 품종(品種)의 조만생에 관계(關係)없이 고온조건하(高溫條件下)에서는 출수기(出穗期)가 오히려 현저히 늦어졌다. 3) Japonica 수도품종군(水稻品種群)에서는 출수기(出穗期)의 단축(短縮)에 미치는 단일(短日)의 효과(效果)가 중만생종에서 크고 조생종(早生種)에서 작았으나 Indica친수도품종(親水稻品種)/계통군(系統群)에서는 단일효과(短日效果)가 품종(品種)의 조만성과는 전혀 무관(無關)하게 나타났다. 4) 고온조건하(高溫條件下)에서의 출수(出穗)까지 일수(日數)는 Japonica품종군(品種群)이나 Indica 친품종군(親品種群)에서 모두 일반재배시(一般栽培時)의 출수(出穗)까지 일수(日數)보다 길었는데 단일조건하(短日條件下)에서는 Japonica 계수도품종군(系水稻品種群)의 출수(出穗)까지 일수(日數)는 일반재배시(一般栽培時)의 출수(出穗)까지 일수(日數)보다 짧았으나 Indica친수도품종군(親水稻品種群)에서는 일반재배시(一般栽培時)의 출수(出穗)까지 일수(日數)보다 길었다. 5) Japonica계(系)나 Indica친수도품종군(親水稻品種群)에서 모두 각파종기(各播種期)에서의 품종(品種)의 조만성과 일반대배시(一般對培時)의 품종(品種)의 조만성간에는 고도(高度)의 유의상관(有意相關)이 인정(認定)되었다. 6) Japonica 계수도품종군(系水稻品種群)에서는 파종기(播種期)지연에 따르는 출수(出穗)까지 일수(日數)의 단축율(短縮率)과 품종(品種)의 조만성간에 비교적(比較的) 높은 상관(相關)($P{\fallingdotseq}0.1$)이 인정(認定)되었으나 Indica친품종군(親品種群)에서는 이 양자문(兩者問)에 전혀 상관관계(相關關係)가 인정(認定)되지 않았다. This experiment was carried out to obtain some imformations about the ecological variations of the heading time of the newly breeded Indica x Japonica varieties/pedigrees according to the seasonal changes of the seeding date. day length and temperature. The results obtained are summarized as follows; 1) At all varieties. days to heading showed a straight reduction according as the seeding time was delayed. 2) At the group of Japonica varieties. the days to heading of early maturing varieties were much shortened and that of medium or late maturing varieties were little or not shortened under high temperature condition but at the group of Indica ${\times}$ Japonica va rieties/pedigrees. days to heading were significantly elongated under high temerature condition. 3) At the group of Japonica varieties. the effect of the short day condition on the days to heading was significantly high at the medium and the late maturing varieties than at the early maturing varieties. however. the short day effect on the reduction of days to heading was not related with the earlyness of each varieties at the group of Indica ${\times}$ Japonica varieties/pedigrees. 4) Days to heading of all varieties under the high temperature condition were longer than that under the ordinary culture. On the other hand, the days to heading of Japonica varieties under the short day treatment were shorter than the days to heading of ordinary culture but at the group of Indica x Japonica varieties/pedigrees. the days to heading under the short day treatment were longer than ordinary culture. 5) At both varieties groups. the days to heading at each seeding time were significantly correlated with days to heading at ordinary cultivation. fl) At the group of Japonica varieties. relatively high correlation(p=0.1) was recognized between the days to heading by delay of seeding time, but at the group of Indica ${\times}$ Japonicava rieties/pedigrees, correlation between the ordinary heading date and the shortening rate of days to heading was very low.

This study aims to provide foundational information to support the development of effective farm- and district-level (si-gun-gu) biosecurity policies against African Swine Fever (ASF) outbreaks in South Korea. Using ASF outbreak data and detailed farm characteristics from 2019, when ASF was first detected in Korea, to April 2023, we estimated farm-level ASF occurrence probabilities through random forest and panel logistic regression models. These probabilities were then aggregated to the district level to facilitate practical biosecurity management. Key factors significantly influencing ASF risk included farm distances from the nearest farm, distancesfrom the nearest ASF-infected farm, herd size, number of neighboring farms within 5 km and 10 km radii, frequency of ASF-positive wild boar detections within a 4 km radius, number of ASF-infected farms within the district, farm distances from roads, and land-use characteristics such as areas of cultivated land, forest, and rivers. Both prediction models demonstrated high accuracy; the random forest model was particularly effective in short-term forecasting, whereas the panel logistic model demonstrated greater utility for medium- to long-term forecasting. Further studies are necessary to clarify the precise causal mechanisms through which these factors influence ASF occurrence probabilities.

To obtain information on the inheritance of the quantitative characters related with the vegetative and reproductive growth of rice, the $F_1$ seeds were obtained in 1974 from the all possible combinations of the diallel crosses among five leading rice varieties : Nongbaek, Tongil, Palgueng, Mangyeong and Gimmaze. The $F_1$'s including reciprocals and parents were grown under the standard cultivation method at Chungnam Provincial Office of Rural Development in 1975. The arrangement of experimental plots was randomized block design with 3 replications and 12 characters were used for the analysis. Analytical procedure for genetic components was followed the Griffing's and Hayman's methods and the results obtained are summarized as follows. 1. In all $F_1$'s of Tongil crosses, the longer duration to heading was due to dominant effect of Tongil and each $F_1$ showed high heterosis in delaying the heading time. It was assumed that non-allelic gene action besides dominant gene effect might be involed in days to heading character. However, in all $F_1$'s from the crosses among parents excluding Tongil the shorter duration was due to dominant gene action and the degree of dominance was partial, since dominance effects were not greater than the additive effect. The non-allelic gene interaction was not significant. Considering the results mentioned above, it was regarded that there were two kinds of Significantly different genetic systems in the days to heading. 2. The rate of heterosis was significantly different depending upon the parents used in the crosses. For instance, the $F_1$'s from Togil cross showed high rate of heterosis in longer culm. Compared to short culm, longer culm was due to recesive gene action and short culm was due to recesive gene action. The dominant gene effect was greater than the additive gene effect in culm length. The narrow sense of heretability was very low and the maternal effects as well as reciprocal effects were significantly recognized. 3. The lenght of the of the uppermost internode of each $F_1$ plant was a little lorger than these of respective parental means or same as those of parents having long internodes, indicating partial dominance in the direction of lengthening the uppermost internodes. The additive gene effects on the uppermost internode was greater than the dominance gene effect. The narrow as well as broad sense of heritabilities for the character of the uppermost internode were very high. There were significant maternal and reciprocal effect in the uppermost internode. 4. The gene action for the flag leaf angle was rather dominance in a way of getting narrower angle. However, in the Palgueng combinations, heterosis of $F_1$ was observed in both narrow and wide angles of the flag leaf. The dominant effects were greater than the additive effects on the flag leaf angle. There were observed also a great deal of non-allelic gene interacticn on the inheritance of the flag leaf angle. 5. Even though the dominant gene action on the length and width of flag leaf was effective in increasing the length or width of the flag leaf, there were found various degrees of hetercsis depending upon the cross combination. Over-dominant gene effect were observed in the inheritance of length of the flag leaf, while additive gene effects was found in the inheritance of the width of the flag leaf. High degree of heretabilities, either narrow or broad sense, were found in both length and width of the flag leaf. No maternal and reciprocal effect were found in both characters. 6. When Tongil was used as one parent in the cross, the length of panicle of $F_1$'s was remarkedly longer than that of parents. In other cross comination, the length of panicle of $F_1$'s was close to the parental mean values. Rather greater dominent gene effect than additive gene effect was observed in the inheritance of panicle l 벼의 생육(生育) 및 수량(收量)에 관(關)한 주요양적형질(主要量的形質)의 유전(遺傳)에 관(關)한 정보(情報)를 얻고져 1974년(年) 농백(農白), 통일(統一), 팔굉(八紘), 만경(萬頃), 금남풍(金南風)을 교배친(交配親)으로 전조합(全組合) 이면교배(二面交配)를 실시(實施)하여 $F_1$종자(種子)를 얻었으며 1975년(年) 이들 $F_1$ 및 교배친(交配親) 품종(品種)을 재배(栽培)하여 여러 형질(形質)을 조사(調査)하고 그 결과(結果)를 Griffing 및 Hayman의 방법(方法)에 따라 유전분석(遺傳分析)을 하였던 바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 통일(統一)을 교배친(交配親)으로 한 조합(組合)에서는 출수기(出穗期)가 늦어지는 쪽이 우성(優性)이었고 출수기(出穗期)가 늦어지는 방향(方向)으로 각(各) 조합(組合)에서 모두 높은 Heterosis를 나타내었던 바 높은 우성효과(優性效果)와 비대립유전자간(非對立遺傳子間)의 교호작용(交互作用)도 인정(認定)되었는데 통일(統一)을 제외(除外)한 품종(品種)을 양친(兩親)으로 한 조합(組合)에서는 출수기(出穗期)가 빠른 쪽이 우성(優性)이었고 상가적효과(相加的效果)가 우성효과(優性效果)에 비(比)해 현저(顯著)히 큰 부분우성(部分優性)을 나타내었으며 비대립유전자간(非對立遺傳子間)의 교호작용(交互作用)도 인정(認定)되지 않았다. 2. 통일(統一)을 교배친(交配親)으로 한 조합(組合)에서는 장간(長稈)쪽으로 높은 Heterosis율(率)을 나타내었으며 간장(稈長)이 긴 것이 짧은 것에 비(比)해 우성(優性)이었고 상가적효과(相加的效果)에 비(比)해 우성효과(優性效果)가 매우 커서 초월우성(超越優性)을 나타내었으며 협의(狹意)의 유전력(遺傳力)은 아주 낮았다. 그리고 교배조합(交配組合)에 따라 모본효과(母本效果)와 정역효과(正逆效果)가 현저(顯著)하였다. 3. 이삭의 추출도(抽出度)는 모든 조합(組合)에서 양친(兩親)의 평균(平均)보다 약간 길었으며 추출도(抽出度)가 길어지는 방향(方向)으로 부분우성(部分優性)을 나타내고 있었다. 우성효과(優性效果)에 비(比)해 상가적작용(相加的作用)이 현저(顯著)히 컷고 광의(廣意) 및 협의(狹意)의 유전력(遺傳力)도 모두 높았다. 추출도(抽出度)에서도 간장(稈長)에서와 같이 모본효과(母本效果)와 정역효과(正逆效果)가 유의(有意)하였다. 4. 지엽각(止葉角)은 대체로 예각(銳角)의 방향(方向)이 우성(優性)이었으나 팔굉(八紘)에서만은 교배조합(交配組合)에 따라 예각(銳角)과 둔각(鈍角)의 두 가지 상반(相反)되는 방향(方向)으로 Heterosis를 보였다. 우성효과(優性效果)가 상가적효과(相加的效果)보다 약간 높았는데 지엽각(止葉角)의 유전(遺傳)에는 교배조합(交配組合)에 따라 비대립유전자간(非對立遺傳子間)의 교호작용(交互作用)도 상당히 크게 작용(作用)한 것으로 보여진다. 5. 지엽장(止葉長)과 지엽폭(止葉幅)에서는 모두 이들이 증가(增加)되는 방향(方向)이 우성(優性)이었으나 Heterosis의 정도(程度)는 교배조합(交配組合)에 따라 각각 다르게 나타났다. 지엽장(止葉長)의 유전(遺傳)에서는 상가적효과(相加的效果)에 비(比)해 아주 높은 우성효과(優性效果)를 보여 초월우성(超越優性)이 인정(認定)되었던 반면(反面) 지엽폭(止葉幅)에서는 우성효과(優性效果)는 적었고 상가적효과(相加的效果)가 매우 크게 나타나 부분우성(部分優性)을 보였으며 광의(廣意) 및 협의(狹意)의 유전력(遺傳力)이 모두 높았다. 그리고 지

This study aims to investigate the content and meanings of a homeroom teacher’s experiences with teaching students in an inclusive class in elementary school based on the autoethnography of the investigator’s experiences of teaching children with the autism spectrum disorder for many years. Based on the analysis results of collected data, the content of experiences was mainly divided into lessons, life guidance, and relations with people around. In the aspect of lessons, there were the lack of professionalism in special education and the confusion over the essence of inclusive education. In the aspect of life, the teacher had experiences of helping children with the autism spectrum disorder adjust to the class by applying a repeated and focused behavior formation method based on the assistance of various people around her. In the aspect of relations with people around, the teacher had subtle tension and disagreement even amid cooperation with people around her under a single goal. These experiences held three meanings: the direction of inclusive education for children with the autism spectrum disorder was not clear in elementary school; there was no effective communication and support between the different systems providing inclusive education; and there were possibilities of inclusive education for children with the autism spectrum disorder. Based on these findings and their implications, the study made proposals for future studies.

조재성,Jae-Seong Joo 한국작물학회 1979 Korean journal of crop science Vol.24 No.3

These studies were designed to define the effects of temperature on the vegetative growth of the korean ginseng, the induction and growth of the ginseng callus and organ differentiation from the callus of ginseng. At the temperature over $25^{\circ}C$. the plant growth of ginseng was significantly decreased and the chlorophyll in the .central parts of leaflets was deteriorated. Induction and growth of the ginseng callus was best at $25^{\circ}C$. High temperature of $29^{\circ}C$ promoted the initiation of roots from callus tissue but the shoot was not initiated at the temperature over $25^{\circ}C$. Shoots initiation from the ginseng callus occurred at $21^{\circ}C$ or lower temperature. 인삼의 재배 및 기내재양시 Callus 조직의 유기와 생장 및 Callus조직으로부터 근 및 경엽의 재분화에 미치는 온도의 영향을 구명하고자 본실험을 수행하였던 바 그 결과를 요약하면 다음과 같다. 1. $17^{\circ}C$ 내지 $21^{\circ}C$에서는 배에서 발아한 유묘가 정상적인 성장을 보였으며 특히 $21^{\circ}C$에서 가장 왕성한 생육을 보였으나 $25^{\circ}C$에서는 경의 신장이 억제되고 엽의 엽록소가 퇴화되었으며 $29^{\circ}C$에서는 잎은 백화고사하고 생육이 정지 되었다. 2. 2년근인삼의 생육역시 $17^{\circ}C$~$21^{\circ}C$에서는 정상적이 었으나 $25^{\circ}C$에서는 경엽의 신장이 억제되고 엽중앙부의 엽록소가 퇴화되는 현상을 보였으며 $29^{\circ}C$에서 가장 왕성하였다. 4. Callus조직으로부터의 근의 재분화는 고온에서 축진되었으며 $29^{\circ}C$에서 발근량이 가장 많았으나 $25^{\circ}C$이상의 온도에서는 경엽의 분화가 거의 없었다. 5. $25^{\circ}C$이상에서 배양하던 Callus를 $21^{\circ}C$로 배양온도를 낮추면 Callus에서 아가 형성되고 경엽이 분화신장된다.
