접근성의 향상과 지역경제

김흥배,강무진,최석우 대한국토·도시계획학회 1995 國土計劃 Vol.30 No.4

It is generally recognized that national economic growth is positively related to interregional accessibility. Surprisingly enough, however, the literature shows that the presence of transportation has been largely disregarded in regional analysis, in part because the recognition of space significantly complicates analysis. Transportation primarily results in price differentials across regions which stem from the cost differential attributable to transport. This price differentials lead consumers to buying products of their region more than products of other regions. This study analyzes the impact of Kyongbu High-Speed Rail on regional economies of Korea. Two fundamental assumptions are made regarding space and distance; no space within a region and distance between regions. A price endogenous multi-regional input-output model is employed. Since regional technical coefficients and trade coefficients are endogenous variables in the model, the impact of Kyongbu High Speed Rail on regional economies is specifically traced through changes of industrial output and employment.

The percentage of spike-bearing tillers in barley(Hordeum vulgare L.) and wheat(Triticum aestivum L.) was considered to be proper method in comparison of tillers instead of counting number of tillers in these crops. Varietal differences of spike-bearing tillers were significant in barley and wheat. In barley the highest percent of spike-bearing tillers was 98.4% and that of lowest was 88.6%. The percentage of spike-bearing tillers in wheat was higher than barley. The highest was 99.6% and the lowest was 90.8%. Other 6 characters also showed varietal difference both barley and wheat. Relationships between percentage of spike-bearing tillers and 6 characters of barley were all negative but only spike length showed significant correlation. Correlation coefficient between percentage of spike-bearing tillers and spike length was positive and significant in wheat. Except the spike length in wheat, other 5 characters were negatively correlated with percentage of spike-baring tillers. Of these culm length, number of grain, and spike weight showed highly significant correlation.

밀의 優秀交配親選定에 關한 硏究

金興培 東國大學校 1991 東國論叢 Vol.30 No.-

Using variance of F_1, F_2, F_3, Y­ values were calculated for 5 characters on the 4 wheat crosses. Upper 5% and 10% of F_5 population were averaged and compared Y­ value to 5% and 10%. Heritability and correlation were estimated to show the relationships among 5 characters. Number of spikes did not agree Y­ value to 5% and 10% average of F_5. Grain per spike, however, considered to be excellent character due to Y­ value fit well with 5% and 10% average of F_5. Grain per plant and spike length were considered to be bad character because there is big difference between Y­ value and 5% and 10% average of F_5. It was considered that the number of spilkelet was a excellent character. Their Y­ values were exactly same with 5% and 10% average of F_5. Estimates of broad-sense heritability were singinficant in the 5 characters and ranged from 59.75 for grain per plant to 85.75 for number of spikelet. Number of spikelet and grain per spike were excellent characters showing high heritability. Correlation coefficient between number of spikes and grains per plant were 0.9538 that is highly significant and the number of spikelet and grains per spike were 0.5645 that is signiticant.

보리의 간장, 경수, 수장, 100입중, 개체당수수 수당입수, 수량등 7개 형질에 대한 광의의 유전역을 조사하고 형질들 간의 표현형상관, 유전상관, 환경상관을 조사하고 또 유전상관에 의해 형질들의 수량에 대한 직접 및 간접효과를 알기 위해 경노계수 분석을 해 본 결과는 다음과 같다. 1. 유전역은 간장이 0.923으로 가장 높았고 다음은 수장이 0.907로 역시 높았으며 수당입수, 수량, 100입중등도 상당히 높은 수치를 나타냈다. 그러나 경수는 0.179, 개체당수수는 0.147로서 상당히 낮은 유전력을 나타냈다. 2. 간장은 100입중과 고도의 유의성있는 표현형 상관이 있었으며 또 높은 유전상관을 보였다. 경수도 수수와의 사이에서 높은 표현형 상관과 유전상관을 보였고 수장은 입수와의 사이에서 높은 표현형 및 유전상관을 보였다. 수량은 수장, 100입중, 입수등과의 사이에서 고도의 유의성 있는 표현형상관을 보였고 또 높은 유전상관을 보였다. 3 . 경노계수 분석결과 간장은 수량에 대해서 직접효과가 없었으며 다른 형질을 통한 간접효과도 없었다. 경수는 직접효과가 다른 형질보다 가장 컸으며 수장과 100입중도 수량에의 영향이 비교적 강한 것으로 나타났다. 수수는 수량에 대해서 가장 큰 부의 직접효과를 보였다. 수수는 경수를 통해서 그리고 입수는 수수를 통해서 강한 간접효과를 보였으며 경수는 수수를 통해서 가장 큰 부의 간접효과를 보였다. Estimate of heritabilities, genotypic and phenotypic correlations and path coefficient analysis were performed for the seven characters of barley cultivars (Hordeum vulgare L.). Heritabilities of broad sense for stem length and spike length were 0.923 and 0.907. Kernels per spike, grain yield and 100 grain weight also showed high heritabilities. High genotypic and phenotypic correlations existed between stem length and 100 grain weight. Grain yield showed highly significant phenotypic correlation with spike length, 100 grain weight and kernels per spike. Genotypic correlations between those characters were moderately high. Number of stem had greatest direct effect but the number of spike had a strong negative direct effect upon grain yield. Kernels per spike via number of spike showed greatest indirect effect and the number of stem via number of spike showed strong negative indirect effect upon grain yield.

Full 3D Level Set Simulation of Nanodot Fabrication using FIBs

김흥배 한국진공학회 2016 Applied Science and Convergence Technology Vol.25 No.5

The level set method has recently become popular in the simulation of semiconductor processes such as etching, deposition and photolithography, as it is a highly robust and accurate computational technique for tracking moving interfaces. In this research, full three-dimensional level set simulation has been developed for the investigation of focused ion beam processing. Especially, focused ion beam induced nanodot formation was investigated with the consideration of three-dimensional distribution of redeposition particles which were obtained by Monte-Carlo simulation. Experimental validations were carried out with the nanodots that were fabricated using focused Ga+ beams on Silicon substrate. Detailed description of level set simulation and characteristics of nanodot formation will be discussed in detail as well as surface propagation under focused ion beam bombardment.

Deep sowing caused elongation of barley plant height but did not cause that of wheat. Long straw wheat variety Yongkwang showed the longest plant height when the seed was planted at 5Cm deep. In both case of barley and sheat, deep sowing caused decreased number of culms. Spike length of barley and sheat were not affected by the sowing depth but spike length of wheat variety Bezostyal was shorter by deep sowing. There was no effect of the both number of grain of barley and number of spikelet of wheat by deep sowing. Positive significant correlation was found between plant height and sowing depth in barley but low negative correlation was found in wheat. Negative correlation was observed between number of culms and sowing depth in barley and wheat. Various correlation from negative to positive was found among varieties. Correlation between number of grain and sowing depth showed 0.985 in Olbori and 0.075 Buhung and others are moderate but positive.

파종심도에 따른 맥류 및 옥수수의 초엽장과 초장의 변화

金興培 韓國作物學會 1994 Korean journal of crop science Vol.39 No.3

보리 4품종, 밀 4품종, 호밀 3품종, 옥수수 1품종을 가지고 파종 심도를 달리 하였을 때 이들 작물들의 초엽장과 식물체장을 조사하였고 또 이들 간의 상관을 조사한 결과를 요약하면 다음과 같다. 1. 보리, 밀, 호밀, 옥수수가 발아할 때 생기는 관 아래의 절간을 중경 또는 지하경 이라고 호칭하고 있는데 지하경으로 부르는 것이 옳을 것 같으며 보리, 밀, 호밀은 초엽이 종자로부터 지하경과 함께 나오고 옥수수는 지하경 정단의 관에서 나오는 것을 확실하게 해두는 것이 좋을 것 같다. 2. 보리의 초엽의 길이는 파종 심도가 깊어질수록 현저하게 길어지고 식물체장도 같은 경향이 있는데 보리의 2cm파종은 6cm, 10cm깊이 파종 보다 현저하게 짧게 나타났다. 품종간에는 차이를 볼 수 없었다. 3. 밀의 초엽 길이도 마찬가지로 파종 심도에 따라 현저하게 길어졌으며 2cm 파종은 6cm, 10cm 파종보다 현저하게 짧게 나타났으나 보리보다는 못하였다. 이것도 품종간 차이는 별로 나타나지 않았다. 4. 호밀과 옥수수도 파종 심도가 깊어질수록 초엽이 길어졌으며 그 변이가 보리와 밀보다 크게 나타났다. 호밀과 옥수수에서 변이가 컸다. 5. 각 작물과 품종들에 있어서 초엽과 식물체장 간에 유의성이 있는 상관을 보였고 칠보 호밀은 고도의 유의성을 나타내었다. The term underground stem is not used correctly as mesocotyle that is the first internode of barley, wheat and rye. Mesocotyle does not elongate and it remain in the seed in case of these crops. The elongated stem is second internode of these crops and not mesocotyle but rhizome or underground stem. The node on which the underground stem is attached is coleoptile node and coleptile is attached here. The objective of this study was to determine if the depth of sowing affect the coleoptile length and plant height. The deeper sowing caused the longer coleoptile length and plant height. Coleoptile length and plant height of 2cm depth of sowing showed significant difference with 6cm and 10cm depth of sowing in barley and wheat. Variation of these two characters were high in rye and corn because these crops were both heterogeneous due to out crossing. All the varieties of 4 crops showed significant correlation between coleoptile length and plant height. Chilbohomil showed highly significant correlation between two characters.

Carbon fiber epoxy composite materials are widely used in the structures of aircrafts, robots and other machines because of their high specific strength, high specific stiffness and high damping. In order for the composite materials to be used in the aircraft structures or machine elements, accurate surfaces for bearing mounting or joints must be provided, which require precise machining. In this paper, the machinability characterisitcs of the drilling operation of the carbon fiber epoxy composite materials was experimental1y investigated. The experimental results are as follows l. The entrance of hole is very good manufacturing existing, but exit come to occur sever surface exfoliation. 2. The cutting force in drilling of the carbon fiber epoxy composite materials is decreased as the drilling speed increased. 3.The hole of the carbon fiber epoxy composite materials is not good manufacturing by use of the standard twist, therefore, the new drill design in order to accurate hole.
