The publication of books on modern agriculture started under the influence of Silhak Thought developed from the late Chosun Dynasty. The common intention found in these publications is the objective to enrich the country through increased agricultural productivity and thus to secure national independence from the surrounding powers. The study reviews three different categories in this area; five general books on agriculture, three on agriculture related legal regulations, and ten books introducing techniques of commercial agriculture. The first category is comprehensive treatment of general agricultural content and the second is legal regulations which affected the contemporary agriculture. The third category is introductory books on commercial techniques aimed at accumulating wealth through agriculture. Silkworm cultivation occupies an important place in these publications owing to the active encouragement given by the Section of Silkworm Cultivation in the Ministry of Agriculture, Commerce and Industry. We can recognise the extensive involvement of Suh Pyung Sook, who served as the Section Chief of Silkworm Cultivation in 1904, by examining introductions and prefaces of many books in this category. The examples of general books on agriculture are 'New Agricultural Administration' (농정신편), 'General Introduction on Agiculture' (농업대요), 'New Textbook on Agricuture' (신찬농업교과서), 'Pragmatic Agriculture' (실리농방신편), Of these, 'New Agricultural Administration' (농정신편) is evaluated as the first publication on modern agriculture. It was written in 1881, and the first edition was published was published in 1901 with the second edition following in 1905. Examples of the second category are; 'The regulation on utilizing uncultivated state owned land' (국유미간지리용법) legislated and declared with the intention of expanding cultivated area, 'Mining and Forestry Regulation' (광임법규), 'Forest Land Regulation' (임야법령) to administer mining and forestry. Books on commercial agriculture take up the highest proportion in the agricultural publication of this period. These cover silkworm cultivation, chicken farming, vegetables and fruits. The books introduce Western techniques with more scientific and rational approach especially on Silkworm cultivation and chichen farming which had become increasingly significant as commercial agriculture from the late Chosun Dynasty.

This study was designed to examine agro-healing services and programs provided and operated by farms in Korea. The results of the analysis of the agro-healing programs and operation of farms were as follows. The purpose of the operation of farms was to raise productivity by managing farms in a cooperative way through agricultural production, education and healing, and to raise income by processing and selling agricultural products. It was difficult to access farms by public transport and thus visitors had to use their own cars. The size of farms varied. The main resources utilized in the surveyed programs were plants, rural environments and landscapes, and agricultural products. The programs were conducted using resources that were commonly found in rural areas. Facilities on each farm were equipped with facilities (indoor and outdoor learning place, gardens, vegetable gardens, orchards, etc.) and convenience facilities (parking lots, drinking fountains, kiosks, etc.) to support program operation. However, facilities for the handicapped and accommodation facilities were insufficient. The programs operated on each farm utilized agricultural resources, farm produce, and rural resources and were classified into activities such as making, feeling, and growing. The average number of people who operated the family-centered program was 2-3, having qualifications such as welfare horticultural therapists, forest interpreters, experience instructors, and social workers. In addition, they had expertise in medicinal food, dietary life, and social welfare, and they also had essential expertise required to operate programs.

농업은 인간의 활동 중 기상 활동에 가장 종속적이며, 기후 변화 및 기상 재해와 같은 대기 변동성의 증가 속에서 농업기상서비스의 중요성은 점점 증가하고 있다. 유용한 농업기상서비스를 제공하기 위해서는 관측 자료의 품질 관리와 더불어 실제 농경 활동 현장을 대표할 수 있는 곳에서의 기상 관측이 필수적이다. 이를 위해 기상청에서는 자동농업기상관측망(AAOS)을 실제 농경지 근처로 재배치하는 등 관측망 환경을 개선하고 있지만, 아직까지 모든 농업기상관측이 실제영농 환경이 아닌 잔디밭에서 이루어지고 있는 문제가 남아 있다. 기온, 상대 습도, 토양 온도, 토양 수분 관측요소는 지표면의 식생 형태와 관개 등의 영농 활동에 큰 영향을 받는데, 현재의 농업기상관측은 이러한 요소들의 영향을 관측하는데 근본적인 한계가 있다. 본 연구에서는 AAOS 관측 자료의 시간적, 연직적 변이를 분석하고, 실제 농경지 위에 설치된 국가농림기상센터(NCAM) 타워에서 관측하고 있는 공통 기상 및 토양 관측 요소를 비교하여, AAOS 관측 자료의 특성 및 문제점을 분석하였다. 분석 시기는 결측이 가장 적고 추수 이전인 8월과 추수 이후인 10월로 선정하였다. 각 관측 요소별로 관측 높이 및 깊이에 차이가 있었으므로, 차이가 가장 적은 높이 또는 깊이 값을 비교대상으로 선정하였다. 기온의 경우 AAOS 4 m 관측 값이 NCAM타워 관측 값이 비해 낮과 밤 또는 추수이전과 이후 모두 낮았으며, 큰 일중 변화 없이 일정한 차이를 유지하였다. 수증기압 역시 NCAM 관측 값이 AAOS 관측 값에 비해 항상 높았으며, 8월이 10월에 비해 더 큰 차이를 보였다. AAOS 순단파복사의 경우 AAOS 관측 반사복사량이 NCAM 관측 값에 비해 높은 경향을 보였다. 한편, 토양 관측 요소는 대기 관측요소에 비해 더 큰 차이를 보였다. 추수 이전인 8월에는 대부분 논에 물이 차 있었으며, 그로 인해 NCAM 관측 토양 온도가 AAOS 관측 토양 온도에 비해 낮았으며, 일 변화 폭 역시 작았다. NCAM 관측 토양 수분은 강수 여부와 관계 없이 지속적으로 포화상태를 유지하는 반면, AAOS 관측 토양 수분은 강수에 의해 증가한 뒤 감소하는 경향을 보였다. 추수 이후인 10월에는 8월과 다른 경향을 보였다. 토양 온도의 경우, NCAM 관측 값과 AAOS 관측 값의 일 평균값은 비슷하였으나 일 변화 폭은 NCAM 관측 값이 더 컸다. 토양 수분은 NCAM 관측 값이 지속적으로 높았으나, 두 관측 값 모두 강수에 의해 상승하고 증발 또는 배수에 의해 감소하는 경향을 보였다. 이상의 결과는 AAOS 관측 자료의 품질 관리 문제와 함께 논과 잔디밭이라는 지표면 피복 및 영농 활동의 영향을 반영하지 못하는 대표성 문제를 보여주는 것으로서, 본 연구는 2011년 이후 이루어지고 있는 기상청 농업기상관측장비의 농지 부근 이동 작업에 이은 후속 조치로, 농업기상 관측을 대표할 수 있도록 잔디밭이 아닌 논, 밭, 과수원 등 실제 지역 대표 농업 현장에 설치되어야 함을 제언한다.

In near future about 500,000 hectares of Japanese larch and pitch pine need thinning to improve crop-tree spacing and reasonable species composition in Korea. Although thinned trees show very little high quality wood, in fact, all the sawed products are suitable for construction and farming materials. Studies on the utilization of thinned small-diameter trees have been implemented in order to increase lumber yield and display the skeleton of farm buildings. The results obtained in this study were summarized as follows: 1. According to Korean Conifers Log Grading System, log grade 3 was 87.4 percent in Japanese larch bolts and 95.8 percent in pitch pine bolts from thinned trees. The ability to identify defects was essential for grading logs. 2. Cutting diagrams of sawing were developed for 1-sided sawing, 2-sided sawing and 3-sided sawing by small end diameter class of bolt and cutting sizes also were found to use effectively lumber with wane. 3. Lumber recovery of Pitch pine was a little higher than that of Japanese larch. The maximum lumber yields of pitch pine by sawing patterns were 87.2 percent for 1-sided sawing, 80.8 percent for 2-sided sawing an 64.1 percent for 3-sided sawing, up yield compared with 58.1 percent for 4-sided sawing. The lumber yield of 1, 2 and 3-sided sawing significantly was higher value than that of 4-sided sawing. 4. Lumber was inspected and graded. Lumber quality of diameter class 12cm was a little better than that of diameter class 8cm, but 90 percent of lumber in diameter c1ass 16cm fell into grade 3. The lumber grade was classified by Korean standard grades of confiers lumber. 5. Lumber from 1, 2 and 3-sided sawing was used to build the skeleton of a farm house ($53m^2$) and greenhouse ($60m^2$) in order to display more efficient use of small diameter trees from thinning 6. Total volume of timber for building a farm house was $8.1m^3$ of imported timber. Timber of $7m^3$, 70 percent of total volume would be substituted imported timber for domestic timber.

자연 생태계의 일부분으로 발생한 삼림은 공기를 맑게하고 수자원을 보존하며, 번식과 멸종의 방지, 휴식공간 제공 그리고 인간생활 환경을 형성하고 보존시키는 역할을 수행한다. 본 연구에서 원격탐사 자료를 이용하여 삼림식생을 분류한 것은 침염수, 활엽수, 농경지 및 초지, 물의 네 가지로 삼림식생정보를 분류하였다. TM 수치영상을 컴퓨터를 이용하여 분류할 경우, 물지역의 특성 값은 제 4밴드에서 7-13 D.N으로 나타났다. 그러나 침엽수, 활엽수, 농경지 및 초지는 모두 비슷한 특성 값이 나타나므로 화상처리를 해야했다. 화상처리를 제 2밴드와 제 3밴드를 합성한 영상을 비연산처리한 결과, 제 3밴드로부터 활엽수 지역은 72-91의 D.N으로 나타나고, 제 1밴드에서의 침엽수 지역은 l18∼136, 제 3밴드에서의 농경지 및 초지는 96-120의 D.N에서 일치하였다. 또한 최대 우도법으로 분류한 결과와 TM 수치영상의 현지답사에 대한 비교오차를 구한 결과 침엽수, 활엽수, 농경지와 초지 및 물에서 각각 －7.43%, ＋1.89%, ＋7.58%, -2.04%의 분류 정확도를 얻었다. 결론적으로 이 결과는 원격탐사 자료를 이용한 삼림식생분류가 매우 유용한 것임이 입증되었다.

The purpose of this study is to understand the relation between the land use status in watersheds and stream turbidity. Major water quality components (flow rate, turbidity, SS, BOD, TN, TP, etc.) of two streams (Jaun and Naerin) and the land use status for each correspondent watershed have been analyzed through the field sampling and the geographical overlaying of land use and watershed map. The detailed results of this study showed that; turbidity has been increased rapidly from 1.9 to 13.0 NTU for Jaun Stream, 0.4 to 0.7 NTU for Naerin Stream, due to the increased flow rate during the period of June. The agricultural area of the Jaun watershed was $13.5km^2$ (10.1% of the overall watershed), comparing to $2.0km^2$(1.4%) of upper watershed of Naerin stream. The forest was widely distributed along the 30m buffering zone from the center of Naerin stream, which comprised 64.14% of the whole watershed area. But in case of the Jaun, the ratio of forest was 17.84%, while the ratio of farming field was 30.33%.
