In the Chosun Dynasty, the wooden building materials for constructing the official buildings within a capital city were supplied by way of water transport, and they were stored at Hangang riverbanks. After being firstly treated with primary processed-goods there by several craftmen groups, they were carried in the relevant site of construction by cart. The purpose of this paper is to study the process of those supply, the roles of merchants and craftmen in the process.

The purpose of this thesis is a searching out the characteristics of Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism and its influences on Korean modern dwellings especially in the time of 1930's. At the early stage of the colonial time(1905~1919), the central corridor type Japanese dwellings were implanted into Korea for the Japanese official residences. The central corridor type Japanese dwelling was an urban modern dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. After the 1920's the central corridor type Japanese dwellings have spreaded itself and became a prototype of a modern dwelling in Korea. The characteristics of the central corridor type Japanese dwellings have influenced on the Korean high class dwellings and Korean architects' proposals for modern dwelling in the time of 1930's. By the implantation and spread of the central corridor type Japanese dwellings, Korean modern dwellings at the same time have affected and undergone transformation. The aspects of transformation were ; The outbreaking of the Japanese style entrance and central corridor, the transformation of MaDang from the inner court with a function of circulation into the outer court garden with plants and the transformation of Korean dwellings from the rural inner court type into the urban outer court type. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

In the time of the rule of Japanese imperialism, Japanese style official residence played major role at the implantation of modern dwellings into Korea and its influences on Korean modern dwellings are distinguishable. This study focuses on the Japanese style official residence implanted into Korea before 1910. Before 1910 Japanese civilians in Korea builded just a traditional Japanese dwellings at the Japanese settlement in the ports opened. But Japanese engineers engaged in governmental organization of construction in the Old-Korean Empire builded a central corridor type Japanese dwellings as official residence. The central corridor type Japanese dwelling was an urban dwelling compromised between Japanese style and western style and distinguished by an outer-court type plan, Japanese entrance hall, central corridor and western style reception room. It is certified that the central corridor type Japanese dwelling was implanted into Korea before 1910 and this was the first time an urban dwelling to be implanted and spread through the whole Korea. The central corridor type Japanese dwelling implanted into Korea took in On-Dol and transformed to Korea-Japanese eclectic style. The central corridor type Japanese dwellings implanted into Korea in the time of the rule of Japanese imperialism makes function as a precedent of a modern urban dwelling to Korean and makes Korean dwellings transform from the rural inner court type into the urban outer court type.

국내산 41종과 79종 식물체 메탄올 추출물 및 일본산 1종 식물체 정유의 솔잎혹파리(Thecodiplosis japonensis Uchida et Inouye) 유충에 대한 살충황성을 여지접촉법과 충제침지법으로 조사한 결과 살추활성은 식물체 종류에 따라 달리 나타났다. 여지접촉법으로 여지당 시료 10mg을 처리하였을 때, 국내산 미나리아재비과의 지범, 부자의 위령선 뿌리 추출물과 일본산 측백나무과의 Thujopsis dolabrata var. hondai 톱밥의 정유가 90%이사의 살충활성을 보였다. 그러나 충제침지법(5,000ppm)을이용한 생물검정에서는 T.dolabrata var. hondai 톱밥의 정유만이 강한 살충활성을 나타내었다. 따라서 T.dolabrata var. Hondai 톱밥의 추출물의 솔잎 혹파리에의한 소나무림의 피해를 줄일 수 있을 것으로 생각된다.

유기농 답전윤환밭 및 연속밭의 옥수수 8품종(얼룩찰1호, 흑점2호, 일미찰, 흑진주찰, 찰옥4호, 미백2호, 대학찰)과 수수 7품종(황금찰, 앉은뱅이수수, 목탁수수, 소담찰, DS202, 남풍찰, 동안메)에서 나방류 발생 및 수량 특성을 조사하였다. 조명나방 성충은 년 3회 최성기를 보였고 담배나방류 성충들은 3-4회 최성기를 보였다. 또한 조명나방 유충에 의한 옥수수 및 수수의 잎과 줄기 피해율은 시간이 지날수록 증가하는 경향을 보였는데, 수수의 조명나방 유충에 의한 피해율은 8월 중순에 급격히 증가하였다. 미흑찰, 얼룩찰1호, 일미찰, 흑점2호, 미백2호 등 옥수수 품종들에 대한 조명나방 유충에 의한 피해율은 윤환밭과 연속 밭 간 통계적으로 유의한 차이(P=0.05)를 보였고, DS202 품종(83%와 89%)을 제외한 나머지 6종 수수 품종들의 조명나방 유충에 의한 피해율은 연속밭에서 높거나 비슷하였다(50-92%). 옥수수의 나방 유충에 의한 이삭 피해율은 5%(찰옥4호)에서 38%(흑진주찰)였는데, 대학찰 품종은 답전윤환밭(33%)에서 연속밭(14%)에 비해 상대적으로 더 높은 피해를 입었다. 답전윤환 수수 포장에서 소담찰(94%)과 DS202(82%)가 높은 피해율을 보였고, 연속밭에서는 7개 수수 품종 모두 78% 이상의 피해율을 보였다. 흥미롭게도 답전윤환밭 및 연속밭의 옥수수와 수수 품종들에 대한 조명나방 유충에 의한 평균 피해율과 평균 침입공수 간에는 각 정의 상관관계(옥수수 r=0.69윤환밭, 0.95연속밭; 수수 r=0.93윤환밭, 0.97연속밭)를 보였다. 또한 수확 후, 유기농 윤환밭 및 연속밭 포장에서 나방 유충에 의한 옥수수 8품종들과 수수 7품종들의 평균 피해율과 이삭무게 또는 천립중(g) 간에 부의 상관관계(옥수수 r=-0.38윤환밭, -0.49연속밭; 수수 r=-0.70윤환밭, -0.57연속밭)를 나타냈다. 이상의 결과는 유기농 옥수수 및 수수 재배포장에서 나방류의 관리가 수량 확보에 매우 중요하다는 사실을 의미한다.

본 시험은 논으로부터 밭으로 윤환한 2년차인 답전윤환밭과 연속밭에 풋옥수수 찰옥4호 등 8품종을 사용하여 윤환밭과 연속밭의 병충해 발생, 생육 및 수량특성 차이 구명은 물론 풋옥수수의 체계적인 유기농 답전윤환 재배기술을 위한 기초자료를 확립하고자 수행한 결 과는 다음과 같다. 유기농 답전윤환 시 주요 병해는 전반적으로 연속밭에 비해 윤환밭에서 발병률이 높았으며, 시험품종 중 저항성 품종으로 발병률이 2% 미만인 흑진주찰과 대학찰 로 판단되었다. 유기농 답전윤환 시 주요 충해인 조명나방 유충 피해는 전반적으로 연속밭 에 비해 윤환밭에서 피해주율이 높았으며, 시험품종 중 저항성 품종으로는 피해주율이 낮 은 찰옥4호와 흑점2호로 판단되었다. 유기농 답전윤환 시 수량은 윤환밭에서 연속밭의 85 % 수준으로 감소하였으며, 답전윤환밭에서는 찰옥4호가 789.0 kg/10a로 가장 수량이 많았 다. 내병성, 내충성, 수량을 종합 평가하면 유기농 답전윤환 시 적합 품종으로는 찰옥4호, 흑진주찰, 흑점2호로 판단된다.

The subject of this experiment is to supply basic data to inhibit non-productive tillers which are uneconomical for mechanical harvesting and to evaluate optimum planting density and sowing date in central district. Total number of tillers and effective first and second of tillers according to different planting density was higher in 80 ㎝ ridge than 60 ㎝ ridge in proso millet. The wider between plant distance on the ridge, the more increased total number of tillers and effective first and second of tillers. The highest effective tillers (91.7 %) in the first tillers was obtained from the second sowing date (23 May) among different sowing date and next is in the order of 3 rd (13 June, 89.8%) > 1 st (2 May, 85.6%) > 4 th (4 July, 85.2%). The percentage of effective tillers in the second tillers was decreased in the order of 2 May (53.7%), 23 May (40.7%), 13 June (22.2%), 4 July (0%) as the sowing date was delayed. There was no significant difference in days to heading and days to ripening according to different planting density. Although culm length was increased as planting density was increased, whereas number of tillers, stem diameter, ear length, grains per ear and 1000 grain weight was decreased. In the growth and yield characteristics of proso millet according to different sowing date, days to heading and days to ripening, culm length, stem diameter, ear length, grains per ear and yield per 10a were decreased. After the sowing date of 13 June, the reduction of growth and yield characteristics were higher because of excess-moisture injury.
