기상요인(氣象要因)과 수도(水稻)의 생육(生育) 및 수량(收量)과의 관계(關係)를 구명(究明)하고자 13개(個) 수도품종(水稻品種)에 대(對)하여 6년간(年間)의 수도(水稻)의 생육(生育) 및 수량(收量)을 조사분석(調査分析)하여 보았던바 그 결과(結果)를 요약(要約)하면 다음과 같다. 1. 평균기온(平均氣溫)의 년차변이(年差變異)는 7월(月) 상중순(上中旬) 및 8월(月) 하순(下旬), 9월상순(月上旬)에서 컸고 6월하순(月下旬)과 7월하순(月下旬)에서 가장 적였다. 일조시수(日照時數)의 년차변이(年差變異)는 1월중구(月中句)에서 가장 컸으며 6월하구(月下句)및 7월하구(月下句)에서 가장 적었다. 2. 수량구성요소중(收量構成要素中) 수수(穗數)의 년차변이(年差變異)가 가장 컸고 현미천립중(玄米千粒重)의 년차변이(年差變異)가 가장 적었으며 품종별(品種別) 각형질(各形質)에서의 년차변이(年差變異)의 정도(程度)는 각각(各各) 다른 경향(傾向)이었다. 3. 수량(收量)에 미치는 직접효과(直接效果)는 등숙비율(登熟比率)이 가장 컸고 다음이 현미천립중(玄米千粒重)이었으며 수량(收量)에 대(對)한 수량구성요소(收量構成要素)의 영향(影響)은 해에따라 상당(相當)히 다른 경향(傾向)을 보였다. 4. 평균기온(平均氣溫)이 높을수록, 그리고 일조시수(日照時數)가 길수록 최고분얼기(最高分蘖期)는 지연(遲延)되었으며 한편출수기(出穗期) 까지의 일수(日數)는 단축(短縮)되었다. 5. 이앙후(移秧後) 11~40일(日)의 평균기온(平均氣溫)과 입수간(粒數間)에는 높은 (-)의 상관(相關)이 인정(認定)되었고 이앙후(移秧後) 61~70일(日)의 평균기온(平均氣溫)과 입수간(粒數間)에는 (+)의 상관(相關)이 인정(認定)되었다. 출수전(出穗前)의 고온(高溫)은 등숙비율(登熟比率)을 증가(增加)시키는 경향(傾向)이 였으나 출수직후(出穗直後)의 고온(高溫)은 등숙비율(登熟比率)을 오히려 감소(減少)시키는 경향(傾向)이 였다. 6. 적산기온(積算氣溫)과 천립중(千粒重) 간(間)에는 전기간(全期間)에서 높은 (+)의 상관(相關)을 보였다. 이앙후(移秧後) 61~70일(日)의 평균기온(平均氣溫)과 현미중(玄米重) 간(間)에 가장 높은 (+) 상관(相關)을 보였고 출수후(出穗後)의 평균기온(平均氣溫)과는 (-)의 상관(相關)을 보였다. 7. 호등숙비율(登熟比率)과 적산일조시수(積算日照時數) 간(間)에는 높은 유의상관(有意相關)을 보였으며 이앙후(移秧後) 31~50일(日) 및 61~70일(日)의 일조시수(日照時數)와 등숙비(登熟比) 율간(率間)에 높은(+)의 상관(相關)을 보였다. 현미수량(玄米收量)과 일조시수간(日照時數間)에는 이앙후(移秧後) 51~60일(日)에서 높은 (+)의 상관(相關)을 보였다. 6 years data on the plant growth and grain yield of 13 rice varieties were investigated to define the relations between meteological conditions and plant growth of rice including grain yield. The results obtained are summarized as follows; 1. Variation of average temperature by years showed great number at early and middle July, middle August and early November, however smallest figure at late June and late July. And that of sunshine hours by years were least at late June and late July, and largest at middle July. 2. Among rice yield components variation of panicle number per hill by years was biggest and that of 1000 grain weight least. Rate of variation of plant growth and rice yield was different by rice varieties. 3. Direct effects on rice yield was greatest at maturing ratio and next at 1000 grain weight. The effects of yield factor on the rice yield wers different by years. 4. Higher temperature and longer sunshine delayed the miaxmum tillering stage but shortened the days from seeding to heading. 5. A significant negative correlation was recognized between the number of panicles per hill and average temperature of 11 to 40 days after transplanting, and number of grains per panicle was correlated with the average temperature of 11 to 70 days after transplanting. High temperature before heading time showed atime decreased maturing ratio. 6. Accumulated temperature was highly correlated with 1000 grain weight in all season. Highest positive correltaion was recognized between grain yield of rice and average temperature of 61 to 70 days after transplanting but correlations between rice yield and average temperature after heading stage were negative. 7. Highly significant correlations were confirmed between maturing ratio and sunshine hours of 31 to 50 days as well as 61 to 70 days after transplanting, and maturing ratio was highly correlated with accumulated hours of sunshine. Correlation between rice yield and hours of sunshine was significant at 51 to 60 days after transplanting.

This study aimed to develop an indicator system for assessing regional agricultural competitiveness and categorizing rural areas accordingly. The indicator system comprises 3 domains, 15 items, and 30 core indicators: regional economic foundation, agricultural structure, and fiscal conditions. The regional economic foundation reflects the fundamental economic basis required for maintaining and developing local industries, while the agricultural structure represents the scale, structure, and characteristics of regional agriculture. Fiscal conditions, on the other hand, mirror the region's financial self-sufficiency and agricultural budget. Domain-specific indices were derived through principal component analysis and correlation analysis between principal components and agricultural production. Employing hierarchical cluster analysis, 154 cities and counties were classified into 5 types: industry-vulnerable areas (25 cities), non-agricultural industrial areas (29 cities), agriculturally-developed areas (27 cities), typical rural areas with scaled and modernized farms (39 cities), and typical rural areas (34 cities).

The purpose of this study is to investigate influence of hakwon on high school students. Two research problems were set to define the research direction. First, this study investigated how the contents of hakwon courses in Korea changed as high school students advanced into a higher grade. The researcher found that students chose different hakwon by their grade level and figured there had to be a reason. With this understanding, firstly, this study intended to discover and interpret elements of changes in school curriculum, class, and college entrance examination system in connection to hakwon. Secondly, the meaning of hakwon to Korean high school students was investigated. The summary of results of this study is as follows. High school students’ experience with hakwon was summarized into three large groups by grade level. First, first grade high school students wanted to prepare for internal school exams which is becoming increasingly important and difficult and they wanted to concentrate on math and English, the key subjects in high school education. Secondly, to second grade high school students, hakwon was a place where they can prepare for KSAT and major subjects they are about to learn in earnest. Specially, it was meaningful since administrative dilemma of high school curriculum triggered by KSAT was resolved. Thirdly, third grade high school students choose EBS KSAT lecture to get high scores in KSAT and this changed paradigm of KSAT studies. In the meantime, significance of hakwon education perceived by high school students was classified into four main categories. First, high school students understood hakwon as an institute to provide customized learning to better meet their own situation and necessities. Second, students perceived hakwon as an institute with the greatest influence and responsibility for high school records and college entrance examination, the most important factors in their lives in the moment. Third, highschool students considered hakwon as a resting place where they can have conversation about themselves and get practical help. This means they saw hakwon is a place where they could have close relationship with their peer students both in learning and personal life. Fourth, experiences in hakwon tended to undermine students’ own learning abilities. In the long run it seems necessary to ensure education to help students find their goals and grow problem-solving ability by searching for answers on their own. Whether it is positive or negative, it is becoming an undeniable fact that high school students are getting a lot of help for college entrance through hakwon education. Hakwon is exploiting the chance and providing satisfactory services for students. Also, the chance is, to some extent, created by schools. Of course, school system is not the only factor that created the loophole and gave the change to hakwon since teaching knowledge and preparing for college entrance exam are not the fundamental goals of school system. However, schools must be changed. Schools need to take measures to correct misconception and misunderstanding on hakwon and need to learn educational method and practical system of hakwon and apply them in schools. This study is expected to provide opportunities for this process to be put into practice. 한국의 고등학생들에게 공부는 그 어떤 것보다도 중요하다. 그들은 공부를 더 잘하기 위해 학 원을 찾는다. 본 연구에서는 고등학생들이 학원을 찾는 현상을 더 깊이 바라보고자 했다. 이를 통해 고등학생을 위한 학원은 어떠한 모습을 갖고 있는지, 그리고 그들이 학원에 가는 이유와 의미는 무엇인지를 탐구하고자 했다. 연구를 실행하기 위해서 각 학년을 대표하는 고등학생을 선정하여 심층면담을 진행했다. 동시에, 고등학생들의 학원 생활을 잘 드러내 줄 수 있는 일정 규모의 학원들을 방문하여 면담 및 참여관찰, 문서분석을 실시했다. 이러한 연구의 결과로 두 가지의 특징을 제시할 수 있었다. 첫째, 학년에 따른 고등학생들의 학원교육 경험의 특징과 변화가 있었다. 학원교육은 역동적이며 학생들이 처한 상황에 따라 자유자재로 변하는 특성이 있었다. 둘째, 고등학생들이 느끼고 있는 학원교육의 의미가 있었다. 학생들은 학원교육을 신뢰 하며, 학원 속에서 자신의 발달을 이루어내려고 하고 있었다. 다만, 고등학생들이 지나치게 학원에 의존하려는 경향도 찾아낼 수 있었다.

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.
