The aim of this study is to explore the purpose and method of reading by examining relevant research from various academic fields. According to the reading theory in the Cho-seon Dynasty, reading was classified as either a way of gaining fame, becoming a gentle man, or solving problems. However, this views have been largely replaced by the belief that reading serves two main purposes: self-discipline and practical usage in this study (Confucian perspectives have been excluded from this approach). The traditional reading method, known as sukookdok-jeongsa, influenced by Chu-tzu's reading, emphasized a fluent reading and a deep reading. A fluent reading (sukookdok) method involved a reading aloud, memorizing, and a repeated reading for the literal decoding. After decoding, a deep reading (jeongsa) involved a reading while taking notes, a reading with reference and a repeated reading for the optimal comprehension. A fluent reading in the traditional reading theory is succeeded by 'a reading for liberal arts' and a deep reading is succeeded by 'a reading for learning'. The sukookdok-jeongsa's various reading methods are useful enough to apply to reading education in the school library. But 'a reading for fun' did not appear in the traditional reading theory.

In addition to the emphasis on filial piety ethics in everyday life, filial piety obtained a further significance in Confucianism which had the strong sense of ancestor worship. This paper focuses on filial piety as a mechanism of continuity within Confucianism and points out that it owed its development to its connection to agricultural culture. The sedentary life with less mobility forged a relative intimacy among people and filial piety was the actual expression of that kind of intimate affection. Yet, filial piety in Confucianism created a unique culture in terms that it not only stipulated material and emotional support for parents but also expected one's piety to the further ancestors through a memorial service and made its connection to the infinite posterity through sons. From the perspective of Confucianism that established filial piety at the turning point from life to death, the self existing in present was not an isolated self anymore. Yet, one can see another characteristic of Confucianism from that filial piety, based on blood bonds, could move beyond paternalism to broaden itself. It could be expanded to the care for strangers. The aged experience and wisdom through agricultural life begot the insight that the nature made its infinite connections with everything through circulation. As a stone thrown in a pond would enlarge its boundary by drawing larger and larger concentric circles, this thought enabled people to enlarge their affection to their parents to universal humanity. In this enlarged network, though it was natural to make distinctions between the closer and the farther, Confucianism sought to overcome it by establishing oneself upright. Confucianism emphasized the moral cultivation with its filial piety concept that contained the diachronic thought penetrating life and death and the broadened perspective relating everything around. In Confucianism, filial piety provided an important medium in forming a moral subject that penetrated life and death and related self and others. Inherent in it is the Confucius thought of continuity that searched for a paragon of a moral human being regardless of time and space.

The spatial and temporal non-uniform distribution of precipitation makes water management difficult. Due to climate change, nonuniform distribution of precipitation is worsening, and droughts and floods are occurring frequently. Additionally, the intensity of droughts and floods is intensifying, making existing water management systems difficult. From June 2022 to June 2023, most of the water storage rates of major dams in the Yeongsan river and Seomjin river basin were below 30%. In the case of Juam dam, which is the most dependent on water use in the basin, the water storage rate fell to 20.3%, the lowest ever. Pyeongnim dam recorded the lowest water storage rate of 27.3% on May 4, 2023. Due to a lack of precipitation starting in the spring of 2022, Pyeongnim dam was placed at a drought concern level on June 19, 2022, and entered the severe drought level on August 21. Pyeongrim dam and Suyangje(dam) have different operating institutions. Nevertheless, the low water level was not reached at Pyeongnim dam through organic linkage operation in a drought situation. Pyeongnim dam was able to stably supply water to 63,000 people in three counties. In order to maximize the use of limited water resources, we must review ways to move water smoothly between basins and water sources, and prepare for water shortages caused by climate change by establishing a consumer-centered water supply system.

3∼6m long plot with 3-4 replications will be practical for yield trials in the early hybrid generations. The C. V. values with 9m long plot was about 6.6％ in variety Yudal and 13.9％ in 12m plot. These results indicate that 9-12m plot with 3-4 replications could be employed in securate yield test in the advanced generations.

The competitive effects of annual weeds on soybeans (Glycine max. (L.) Merr. 'Gwang Gyo') were Studied on silt clay loam soil. Weeds allowed to grow in the row for 2, 4, 6, 8, 10 weeks after soybean planting and full season reduced soybean yields 6.5, 3.2, 10.7, 8, 8.24.4, and 44%. respectively. Reduction in leaf area index (LAI) and crop growth rate (CGR) of soybeans were closely correlated to percent soybean yield reduction. Weed com petition showed to reduce the number of soybean pods per plant, the number of branches per plant, and plant height.

45일된 암컷 English Coca Spaniel(0.65kg, 증례 1)과 60일 된 암컷 진돗개(2.05 kg, 증례 2)가 항문폐쇄증으로 내원하였다. 증례 1은 생후 5일부터 만성적인 설사를 보였으며, 내원 7일 전에 이유시켜 상업용 건사료로 바꾸었다. 내원 당시의 임상증상은 복부팽창, 식욕부진, 항문폐쇄 그리고 질 주위에 오줌과 변으로 오염되어 있었다. 증례 2는 내원 당시 우울증, 복부팽만, 항문폐쇄 등의 임상증상을 보였고 질 주위에 수양성 변으로 오염되어 있었다. 증례 1과 2에서 직장 조영술을 실시해서 직장과 질에 누공이 형성되고, 결장이 팽만되어 있음을 확인하고 수술을 실시하여 누공을 폐쇄하고 항문 형성술을 실시하였다. 증례 1은 수술직후 항문에 변이 불연속적으로 배출되었고, 2달후에는 정상적인 항문괄약근의 운동을 관찰할 수 있었다. 증례 2는 술후 4일에 식욕부진과 원기소실로 폐사하였다.

These studies were carried out to clarify the effects of black P.E. mulching and planting density on the growth and rhizome yield of Jihwang #1, a new high yielding Rehmannia glutinosa variety. Emergence ratio was higher 3.1％ in mulching than in non-mulching, but was not affected by planting density. Plant height and fresh leaf weight per plant were increased by mulching and at lower planting density. However, the fresh leaf weight per unit area was increased at higher planting density. Dry rhizome weight was increased 28% in mulching than that of non-mulching. Dry rhizome weight per plant was increased, but that of per unit area was decreased at lower planting density.

In this study, I would like to review how our ancestors understood and used caves for which purposes, and also to research the good use of caves as residential area, myths and tales, proverbs and civilian religions through folk customs' approach to caves. in pre-historic age, I understood that the caves was used for residential area and for food life by various archeological data. I could review the meaning of caves through Dangoon myth and deeply comprehend the caves, as every cave has it's own tales related with mysterious world. Caves are spotlighting as proverbs related with unknown world, and the caves as prayer place and mental training place, and also as foods warehouse, military facility, and play space I.E sightseeing place from a viewpoint of modern living folk customs.

An artificial lodging was made at various growth stages of the rape varieties Yongdang and Mokpo 29 to evaluate its effect on seed yield and other important agronomic characters. Results showed general increases in plant height and number of branches per plant whereas reductions in 1.000 grain weight, number of pods and seeds per plant in the severly lodged plots. As compared to control of lodging, about 29 percent yeild reduction was caused by the severe lodging treatment. Further more, the most severe lodging before blooming resulted in about 60% yield losses.

소과종 수박의 고밀도 지주재배시 질소시비량을 260kg/㏊, 200, 140, 0, 무비구로 하여 생육, 수양, 품질 및 무기양분 흡수에 미치는 영향을 조사한 결과는 다음과 같다. 가. 생육특성은 질소시용구가 0kg시용구와 무비구보다 초장, 엽면적, 생체중 및 건물중이 좋았고, 질소시용구간에는 차이가 없었으며 엽수는 모든 처리구에서 차이가 없었다. 나. 수량특성은 140kg/ha시용구가 32,010kg/ha로 가장 높았고, 착과율도 79%로 가장 높았다. 다. 품질특성은 140kg 시용구가 식미지수 3.9, 당도 12.5 $^{\circ}$Bx로 다른 처리구보다 좋았고, 무비구가 12.0 $^{\circ}$Bx로 처리구 중에서 가장 낮았다. 과피두께는 질소 시비량이 증가할수록 두꺼웠다. 라. 식물체(잎)내 T-N의 함량은 질소시비량이 많았던 처리구일수록 증가폭이 컸으며, 모든 처리구에서 생육중기에 가장 많이 흡수되었다. 인산함량은 질소시비량에 따라서 큰 차이가 없었으며 칼슘함량은 질소시비량이 많을수록 증가하는 경향을 보였고, 마그네슘 함량은 칼슘과는 달리 질소시비량이 많을수록 생육후기에 낮았다. 마. 이상의 결과를 종합해 보면 소과종 수박을 밀식하여 지주재배를 실시할 때 토양 염류집적을 줄여주고, 품질 및 수량을 향상시키기 위해서는 질소시비량을 대과종 수박재배시의 70% 수준으로 줄여서 시비하는 것이 바람직하다고 사료된다.
