Experiments were conducted by moderate season culture of each of 7 early, medium and late maturing varieties which were considered to be of strong salt tolerance in non-salty, low- and high-salty reclaimed areas (salt content: 0.5% and 1% at the end of April). The results of the experiments revealed that the early maturing varieties were suffered greatly from salt damage in such reclaimed salty area which is the "fall better type" in the year-round changes of soil salt concentration in Korea. Better yielding varieties in the salty area showed generally a high yield ratio in the salty area compared with the non-salty area. This indicates that they are strong salt tolerant varieties. It seemed that the salt tolerance could be measured by the number of delaying days in heading, the growth rate of culm length, number of panicles and number of grains per panicle in the salty area to compare with the non-salty area. The effects or salt damage on the yields of each variety at maturing stage and agronomic characteristics in the salty area were compared and discussed with the non-salty area.alty area.

우리나라의 인쇄문화를 꽃피웠던 조선조에 있어서 교서관은 전기 및 후기 즉 전대를 통하여 서적의 인출을 관장하던 기관으로 조선조 문화창달의 산실이었다고 볼 수 있을 것이다. 그러므로 이어서 인출된 서적에 관한 연구는 즉 조선조의 관판에 대한 분석의 일환으로서 이를 통해 당시의 시대 사상 및 문화의 특징을 알수 있는 바, 본 연구에서는 우선 교서관 자체의 변천 과정 및 그 기능과 함께 조선왕조 후기에 있어서 가장 문운이 진작되었던 정조조을 중심으로 당시 교서관을 통해 간행되었던 서적들의 성격을 규명해 보고자 한다.

The best way of getting knowledge is reading in the Cho-sun dynasty, so getting books is the most interesting thing to the scholars. The most important way of getting books for scholars in Cho-sun dynasty is taking Bansabon published and given to scholars by government. but there is few data and few concrete studies of it. This study deals with the object and the scale of distribution of books on the basis of Bansagi ; king Jeong-jo published 『Kyujangjeonun』 distributed about 1,500 volumes to scholars and govermment agencies.

The purpose of this study is to measure fundamental data required for the prediction of rice quality and to develop regression models to predict protein, amylose, moisture and fatty acid contents, and Toyo taste meter value (TTMV) of brown and polished rice from hulled rice NIR spectra. NIR spectra of hulled rice measured in transmittance mode (850-1050 nm) and in reflectance mode (400-2500 nm) were used to predicted chemical compositions of brown rice and polished rice. For most chemicals, the transmittance spectra could provide better calibration results than the reflectance ones. Beside the Toyo taste meter value (TTMV), the hulled rice spectra could predict chemical contents with the determination coefficients higher than 0.8. Spectra of hulled rice measured in transmittance mode could be used for the prediction of chemical compositions in brown rice and polished rice precisely. However, taste value of polished rice was a constituent that was hardly to be predicted.

Uptake amount, percent translocation to grain and grain yield efficiency of N. P. K. Si were investigated with N. P. K simple trials (countrywide, 1967~69) and other nitrogen fertiltzer field trials in relation to yield class. 1) Uptake rate with yield increase were similar in all nutrients but silica showed greater yearly variation. 2) In N. P. K simple trials showing very low nitrogen efficiency(46kg grain/ nitrogen uptake kg) it and percent translocation increased with yield increase. 3) Nitrogen efficiency deacreased with the increase of nitrogen uptake and the decreasing rate depends greatly on fertilizer forms and variety. Nitrogen efficiency was greater in sandy loam where yield was higher than in clay loam. 4) Nitrogen efficiency positively correlated with percent translocation. 5) In high yielding fields yield was attributed only to the increase of nitrogen uptake, keeping efficiency around 50. 6) Major factor for high yield is considered as the increase of nitrogen efficiency rather than nitrogen uptake. 7) Phosphorus efficiency in N. P. K. simple trials was considerably low, suggesting too much uptake due to soil reduction.

This paper is an essay on Chaekmun(Answer papers of official examination in Pre-modern period). Especially I tried to point out the possibility of practical use in the field of politics. For this purpose, I analyzed an examination paper written by Lee Ga-hwan, and the title is "a debate about construction of the Miang palace". Exquisite writing skill is also important in Chaekmun, but it is not everything. The subject of Chaekmun concerns various fields such like politics, economy, society, culture, and history. So that writers should have sufficient knowledge and opinion. The King, as an examiner, wants to test retainers' ability both in writing and politics. In this paper, I focused on using in field of politics between the King and the retainers. And as an good example, I analyzed a paper which dealt the event of building huge palace named Miang palace. That is because the King reflects his concerns by setting exam questions. And his concerns also could not be free of contemporary political conditions. Therefore we should be careful of reading those articles. Regarding this, Lee Ga-hwan's article had a distinctive characteristic. Unlike any other articles dealing with same event, he tried to access through creative point of view. And his thought were much close to the King's heart.
