Lee,Jun-Ki,Hyun,Sang-Ki,Lee,Sang-Sun,Chai,Jung-Ki 한국자원식물학회 2002 Plant Resources Vol.5 No.1

Twenty-three plants of Japanese apricot (Prunus mume) were collected from several sites around Mountains JIRI in Korea. Japanese apricots having the different morphological features were evenly distributed in the groups made from the cluster analysis, indicating no geographic distributions but artificial vegetations in Korea. Japanese apricots were, as based on the PCR-RAPD techniques, clustered into the three groups; a group (prototype) having the five white petals with the five red sepals, a group (green type) having the five white petals with the five green sepals, and a group (hybrid type) having the more than five red petals with various colored sepals. The prototype apricots showed higher toxicities than other type apricot against bacteria and production of less compounds in TLC plates. The polypetal types of Japanes apricot were related to those of p. armebiaca in the characteristics of seed (the ruggedness), but also to be closed to those of p. armebiaca in PCR-RAPD analysis. The cluster analysis of the twenty three apricots and its related species calculated from the two primers were shown to distinguish relationships of cultivars within species, or of individual plants within cultivars, but also to display the two overlapping bands resulted from PCR-RAPD technique.

잣나무 조림지를 대상으로 가지치기의 정도가 임목의 생육에 미치는 영향과 가지절단방법이 절단면의 유합속도에 미치는 영향을 알기 위하여 가지치기 정도와 가지절단방법을 달리하여 시험조사된 본 연구에서는 다음과 같은 결과를 얻었다. 1. 가지치기한 후 2년까지는 수고생장이 가지치기 정도의 영향을 받는 것으로 나타났지만 그 이후부터는 그다지 영향을 받지 않았다. 2. 흉고직경생장에 있어서도 가지치기 정도의 영향을 크게 받지 않는 것으로 나타났다. 3. 가지의 절단면 형태에 따른 유합정도는 지융부 포함 절단법(91.9%)이 지융부 제외 절단법(78.0%)보다 더 높은 유합정도를 나타내었다. 4. 가지의 절단직경의 크기와 유합정도와의 상관관계는 처음 2년간은 두가지 방법에서 모두 유의성을 인정할 수 있었는데 특히 지융부 포함 절단법은 절단후 2년동안은 절단직경이 클수록 빠른 유합정도를 보였으나 어느정도의 유합이 이루어진 후에는 절단직경의 크기와 유합정도 사이에는 유의성을 찾을 수 없었다. This study was conducted to find out the effect of pruning on tree growth and the effect of pruning methods on healing of wound orientated Pinus koratensis afforested land. Through-out a different test in pruning and cutting-methods of pruning obtained result as follows. 1. Degrees of pruning have an effect on height growth for two years after pruning but since that time they not an effect on height growth. 2. Degrees of pruning have not an effect on D.B.H. growth. 3. Healing rate by pruning method were B method(straight angle cut line 91.9%)higher than A method(end of turgid cut line(78.0%). 4. Correlation coefficients between healing of wound and diameter of cutting face were allowed significant in A method(P>0.05). The larger the diameter of cutting face was the faster the healing of wound in all methods for two years. But B method was allowed no significant after two years.

본 실험은 수도에서 문제 잡초로 대두되는 올방개의 효과적인 방제법을 구명하고자 sulfonylurea계 제초제를 각각의 약제간, 시기별로 구분하여 처리하였고, 주요 결과는 다음과 같다. 1 약제처리시기에 따른 올방개 방제효과는 이앙 후 10일 처리에서 Bensulfuron-methyl, Pyrazosulfurone-thyl, Azimsulfuron, Imazosulfuron, Halosulfuron, Cinosulfuron, Cyclosulfamuron 이상 7종이 올방개 방제효과가 우수했고, 이중 Bensulfuron-methyl, Pyrazosulfuron-ethyl, Azimsulfuron, Imazosulfuron은 이앙 후 20일 처리에서도 방제효과가 우수했다. 2 Pyrazosulfuron-ethyl + Mefenacet 합제를 시기별로 처리한 결과 이앙 후 14일과 21일 처리에서 90%이상의 방제가를 보여 우수한 방제효과를 보였던 반면, 이앙 후 7일과 28일 처리에서는 방제효과가 떨어졌다. 3. Befurasate는 Pyrazosulfuron-ethyl과 Azumsulfuron을 혼합사용하였을 때, Cyclosulfamuron은 Azimsulfuron과 혼합사용하였을 때 올방개의 방제가 증대되는 상승적 작용이 관찰되었다. 4. 이앙 동시처리제인 Imazosulfuron + Fentrazamude 합제, Imazosulfuron + Oxaziclo mefone + Dymron 합제, Bensulfuron-methyl + Fentrazamide합제의 경우 올방개의 방제가가 각각 68%, 76% 66%로, 이앙 후 10일에 처리한 Pyrazosulfuron-ethyl + Mefenacet 합제보다 방제가가 낮아, 올방개가 우점된 논에서의 이앙 동시처리제에 의한 올방개 방제는 어려운 것으로 판단되었다. Sulfonylureas are quite recent low dosage and wide spectrum herbicides, popularly used in paddy rice field. The acetolactate synthase inhibitors are effective for the control of broad leaf and perennial paddy weeds, however for the control of Eleocharis Kuroguwal Ohwi has been reported less than satisfactory. Therefore, present commercial sulfonylureas were evaluated for the control efficacy of Eleocharis Kuroguwal Ohwi and the time of application was studied for the better control. Among the tested sulfonylureas, Bensulfron-methyl, Pyrazosulfuron-ethyl, Azimsulfuron and Imazosulfuron exhibited 80% or better control efficacy at both treatments of 10 and 20 days after transplanting (DAT). While Halosulfuron, Cinosulfuron, and Cyclosulfamuron showed good weed control from 10 DAT treatment, but showed less than desirable results at 20 DAT treatment. Ethoxysulfuron showed low control efficacy at both of the time applied. Benfurasate, alone, appeared not effective for the control of Eleocharis kuroguwal Ohwi. Evaluation for the timing of the herbicide application showed that 14 to 21 DAT treatments appeared appropriate. When applied before the period, the weed regrowth became problematic. On the other hand, when applied the later, the weed outgrew to be controlled with the herbicide. For labor saving for herbicide application, herbicide application at transplanting was sought. However, Elevcharis kuroguwal Ohwi was difficult to control from the earlier application, the herbicide application at transplanting appeared impractical where Elevcharis kuroguwai Ohwi is dominant.

자연환경방사선의 세 가지 주요 요소인 지각방사선, 우주선 전리성분 및 라돈과 그 자핵종이 주는 선량을 측정, 해석하였는 바 18개월간에 걸쳐 대전, 수원, 경산 지역에 대하여 수행하고 이를 종합하여 유효선량당량으로 평가하였다. 지각방사선과 우주선 전리성분 측정을 위하여 3"∮×3" Nal(Tl) 섬광검출기와 휴대형 다중파고분석기를 이용한 감마선 분광분석 및 ^7LiF PTEE disk TLD에 의한 적산선량측정을 병행하였고, 공기중 라돈농도의 측정은 CR-39 고체비적검출기를 내장한 라돈컵을 설계제작하여 사용하였으며 비적수 라돈농도 교정인자는 스웨덴 국립방사선 방호연구소의 표준 라돈 챔버내에서 조사하여 결정하였다. 세 지역의 가연방사선에 의한 유효선량당량에는 약간의 수치적 차이는 있었으나 본질적 차이는 찾아볼 수 없었으며 지역 측정치의 분산가중 평균치는 지각방사선 (463±3)uSvㆍy^-1[(52.9±0.3)nSvㆍh^-1], 우주선 전리성분 (287±15)uSvㆍy^-1[(32.8±1.7)nSvㆍy^-1]로 외부 피폭이 (775±9)uSvㆍy^-1[(88.5±1.0)nSvㆍy^-1]였으며 라돈과 그 자핵종에 의한 내부피폭은 (1973±298)uSvㆍy^-1[(225.2±34.0)nSvㆍy^-1]였다. 따라서 자연황경방사선에 의한 여간 총 선량당량은 (2762±296)uSvㆍy^-1[(315.3±34.0)nSvㆍh^-1]로 평가되었는데 이 값들은 UN보고서^(11)에 나온 “정상적 자연방사선 지역”의 값과 비교할 만한 타당한 값으로 나타났다. Assessment of effective dose equivalent from natural environmental radiation that consists of terrestrial gamma­ray, ionizing component of cosmic­ray and alpha­rays of atmospheric radon and its decay products has been carried out for 18 months in Daejeon, Suwon and Kyungsan areas. A 3"∮×3"cylindrical Nal(Ti) scintillation detector in association with portable multichannel analyser and ^7LiF PTFE disk TLDs were used for the measurement of terrestrial gamma­ray and cosmic­ray ionizing component, while self­designed radon­cups with CR-39 SSNTD attached to the inside bottom were used for the integral measurement of at­mospheric radon concentration. Determination of calibration factor for converting track density of CR-39 detector to radon concentration was made by irradiation of radon­cups in the standard radon chamber of Swedish National Institute of Radiation Protection. Although resultant effective dose equivalents of three different measurment points show minor numerical differences, no essential discripancy between the places was found. The variance weighted means of the annual effective dose equivalents of each component of radiation from the tree places came out to be: (463±3)uSvㆍy^-1[(52.9±0.3)nSvㆍy^-1] for terrestrial gamma­ray, (287±15)uSvㆍy^-1[(32.8±1.7)nSvㆍy^-1] for ionizing component of cosmic­ray and (1973±298)uSvㆍy^-1[(225.2±34.0)nSvㆍy^-1] for internal exposure of radon and its decay products. Consequent total effective dose equivalent turned out to be (2762±298)uSvㆍy^-1[(315.3±34.0)nSvㆍy^-1], which if reasonably comparable with that appeared in UNSCEAR Report^[11]as per caput annual effective dose equivalent in “areas of normal back ground radiation.”

This study shows an alternative method for the determination of object's position, based on a computer vision method. This approach develops the vision system model to define the reciprocal relationship between the 3-D real space and 2-D image plane. The developed model involves the bilinear six-view parameters, which is estimated using the relationship between the camera space location and real coordinates of known position. Based on the estimated parameters in independent cameras, the position of unknown object is accomplished using as sequential estimation scheme that permits data of unknown points in each of the 2-D image plane of cameras. This vision control method is the robust and reliable, which overcomes the difficulties of the conventional research such as precise calibration of the vision sensor, exact kinematic modeling of the robot, and correct knowledge of the relative positions and orientation of the robot and CCD camera. Finally, the developed vision control method is tested experimentally by performing determination of object position is the space using computer vision system. These results show the presented method is precise and compatible.

The present study investigated the effects of varying durations of nursery diets differing in percentages of milk products on growth performance of pigs during the nursery phase (NP) and subsequent grow-finish phase (GFP) to find the feasibility of reducing the use of nursery diets containing costly milk products. A total of 204 21-d-old weanling female and castrated male pigs were subjected to one of three nursery phase feeding programs differing in durations on the NP 1 and 2 and GFP diets containing 20%, 7%, and 0% lacrosse and 35%, 8%, and 0% dried whey, respectively, in 6 pens (experimental units) for 33 d: HIGH (NP 1, 2 and 3 diets for 7, 14, and 12 d), MEDIUM (NP 2 and 3 for 14 and 19 d), and LOW (NP 2 and 3 and GFP 1 for 7, 14, and 12 d). Subsequently, 84 randomly selected pigs [14 pigs (replicates)/pen] were fed the GFP 1, 2 and 3 diets during d 54-96, 96-135, and 135-182 of age, respectively. The final body weight (BW) and average daily gain (ADG) of nursery pigs did not differ among the HIGH, MEDIUM, and LOW groups (14.8, 13.3, and 13.7 kg in BW and 273, 225, and 237 g in ADG, respectively). The average daily feed intake during the nursery phase was greater (p < 0.01) in the HIGH group than in the MEDIUM and LOW groups, whereas the gain:feed ratio did not differ across the treatments. The BW on d 182 and ADG during d 54-182 were greater in the HIGH and MEDIUM groups vs. the LOW group (110.0, 107.6, and 99.6 kg in BW, respectively; p < 0.01). The backfat thickness and carcass grade at slaughter on d 183 did not differ across the treatments. In conclusion, the MEDIUM program may be inferior to the commonly used HIGH program in supporting nursery pig growth. Nevertheless, the former appears to be more efficient than the latter in production cost per market pig whereas the LOW program is thought to be inefficient because of its negative effect on post-nursery pig growth.
