한국 재래종 대두(Glycine max) 943계통과 강원도 지성 수집종 야생종(G.soja) 50계통을 polyacrylamide gel electrophoresis와 isoelectric focusing 전기영동으로 LAP 동립효소를 분석한 결과를 요약하면 다음과 같다. PAGE에 의한 Lap1*b는 재래종과 야생종에서 가장 흔한 대립인자였다. Lap1*b의 대립인자 빈도는 한국 야생종(0.94)에서보다 재래종(1.00)에서 더 높았다. 이러한 결과는 한국 재래종 대두는 Lap1 유부자좌에서 Lap1*b 대립인자로 고정되어 있음을 나타내는 것이다. IEF 전기영동법을 이용하여 pH 4∼6.5의 gel에서 LAP 동립효소의 band type을 확인한 결과 재래종과 야생종에서 I type과 II type의 band type을 확인하였다. 재래종과 야생종에서 II type이 6계통(7.2％)과 4계통(8.0％)으로 각각 나타났고 I type은 79계통(92.8％)과 46계통(92.0％)으로 각각 나타났다. 이러한 결과는 다양한 band type이 나타날 수 있는 가능성을 제시하고 있다.

본 연구에서는 약콩(Glycine soja Siebold et Zucc.) 분획 추출물의 미백효능을 관찰하기 위해 B16F10 멜라노마 세포에서 TRP-1 (tyrosinase related protein-1), TRP-2 (tyrosinase related protein-2), 티로시나제 발현을 평가하였다. 그 결과 약콩 분획 추출물 0.125, 0.25, 0.5, 2.0 mg/mL 농도에서 82% 이상의 높은 세포생존율을 나타내었다. ${\alpha}$-melanocyte stimulating hormone (${\alpha}-MSH$)을 처리한 B16F10 멜라노마 세포에 약콩의 EtOAc 분획 추출물을 처리한 결과 티로시나제 발현이 감소되었으며 TRP-1, TRP-2 단백질 발현이 감소하였다. 이러한 결과는 약콩 분획 추출물이 멜라닌생합성과 관련되는 단백질의 발현을 감소시켜 피부 미백효능을 나타내는 것으로 기대할 수 있다.

Genetic improvement of the cultivated soybean [Glycine max (L.) Merr] may be possible through hybridization with its wild progenitor, G. soja Sieb. & Zucc. Interspecific cross between G. max (Hwangkeumkong) and G. soja (IT.182932) was made in the summer of 1997. In F$_2$ the percentage of plant height, nodes per plant, and pods per plant were high but gradually reduced from F$_2$ to F$_4$. In contrast pod length, seeds per pod, and 100-seeds weight were increased gradually through generations advanced. Wild variation as evident in F$_2$ in plant height, number of branches, pods per plant, and 100-seeds weight. Twenty six percent of the F$_2$, 44 % of the F$_3$ and 60% of the F$_4$ segregants showed more G. max traits. The combination of useful traits from both species is possible through interspecific hybridization. The characters that could be transferred from wild species to cultivated species are more pod number, better capacity, and resistance to disease and insects. The interspecific derivatives offer scope for selection for high grain yield. Therefore, introducing genes from G. soja to G. max could be contribute to greater genetic diversity of future cultivars. And semicultivated soybean had some desired characteristics including tolerance to adverse environments and multi-seed characters. It means the infusing of semicultivated germplasm to the cultivated soybean could increase number of seeds and pods per plant significantly, and consequently could enhance selecting potential on yield.

Starch gel electrophoresis was used to examine the banding pattern of Esterase isozyme in the leaf, root-nodule and seedling of four wild legume species, Trifolim repense, Glycine soja, Phaseolus nipponensis and Vigna uexillata. The number of band, enzyme activity and migrating rate of esterase isozyme varies depending on the species and tissues of legume plants. The isozyme banding pattern in the cotyledon and radicle of T. repense showed same pattern, however, the number of band were varible among the cotyledon of G. soja, P. nipponensis and V. vexzllata, respectively. Est-1 in the leaf of G. soja, V, vexillata. root-nodule of G. soja and seedling of V. vexillata expreesed the highest enzyme activity. The Est-1 showed the rapidest migrating rate among the isozymes.

The esterase isozyme in tissue of wild legume plants were separated by horizontal starch gel electrophoresis. Extracts used in this study were prepared from fully expanded young leaf, cotyledon and radicle of seedling and root-nodule of Glycine sola, Vigna vexillata var. tsuscmensis and Trifoliwn repens. The results are as follows; 1. Each tissue examined had a characteristic banding pattcrn. Number of bands in each species, G. soja, V. vexillata, and T . repens, were 14, 8 and 1 1 bands, respectively. And difference in esterase isozyme bands were greater from tissue to tissue than difference between habitat. 2. Est-I, Est-2. Est-3 and Est-4 in G. soja, Est-I in V. vexillata and Est-l and Est-2 in T. repens showed strong cnzyme activity than other enzyme. 3. Esterase isozyme variation in G. soja and T . repens showed more variety than V. vexillata. This is resulted from many genotypic differences within species. 4. The main enLyme among thc esterase isozyme were Est-I. Est-2, Est-3 and Est-4.

The rates of litter production and decomposition of litters from grasslands and forests in Mt. Guryong were studied. The annual litter production of Glycine soja showed the highest value 1950.88 g/$m^2$/yr in the grasslands and that in Quercus acutissima, as 2202.38 g/$m^2$/yr in the forests. The highest decay rate of the grasslands was found in G. soja as k=0.713 and that of the forests was in Salix koreensis as k=0.319. The Z values of k in the grasslands was higher than that in the forests. The shortest half-time of the litter decay in the grasslands was 0.9 years in G. soja and the longest one of the forests was S. koreensis as 2.1 years and the longest of all was Q. mongolica as 5.2 years. In the amount of total nitrogen of litters, G. soja was the highest of the grasslands and S. koreensis was the highest of the forest. The content of the total nitrogen in litters was directly propotional to the decay rates.

한반도 남부지역에 분포하는 돌콩(Glycine soja) 종자의 galactomannan조성과 관련한 지리적 변이를 추적하기 위하여, 북위 $34^{\circ}50'00"\sim38^{\circ}12'00"$ 사이에 위치한 8개 지역(속초, 원주, 치악산, 청주, 안동, 대구, 울산, 사천)을 선정하여 채종한 종자를 재료로 mannose와 galactose의 정량분석을 실시하였다. 각 지역별 mannose의 함량은 최저 55.23 mg/g(사천)에서 최고 460.00 mg/g(안동)의 범위 내에서 다양하게 나타났다. Galactose의 지역별 함량 역시, 최고 387.50(울산)에서 최저 67.17(사천)에 이르는 다양한 수치를 보였다. 환경적응과 관련한 생태지표로서 종자의 경실도(硬實度, seed hardness)를 의미하는 mannose/galactose 함량비를 산출한 결과, 지역에 따라 $0.41\sim1.73$의 값을 나타내었고, 대체로 중북부형(원주, 치악산, 청주), 중남부 내륙형(안동, 대구) 및 해안형(속초, 울산, 사천) 의 3개 유형이 구분되었다. mannose/galactose 함량비의 전반적인 경향은 중남부 내륙형에서 비교적 높은 수치를 보였고, 중북부형에서 상대적으로 낮은 수치를 보였다.

This paper aims to introduce and understand critically the work of Edward Soja, mainly the First part of the which develops his own concepts, such as 'synekism', 'trialectics of space', 'regionality' and 'geohistory'. Most of all, in explaining Geohistory, he emphasizes three 'Urban revolutions': First Urban revolutions in Jericho and ÇatalHüyük, which shows first synekism as proto urban society, Second in Ur and other Sumerian cities where appeared a concentrated power of central government and its transcendental ideologies, and Third in Manchester and in Chicago, typical capitalist cities. These three urban revolutions don't correspond to the established historical periodization. In order to understand these revolutions, it is necessary to comprehend the concept of 'machine' of G. Deleuze and F. Guattari, inspired, in fact, by Lewis Mumford - Primitive Territorial machine, Barbaric Despotic machine, and Civilized Capitalist machine. However, these periodization and concepts of E. Soja have to be applied very cautiously in accordance with concrete historical sources, avoiding theoretical distortion on positivity of historical facts.

Glycine soja Sieb. et Zucc., a predominantly selfing annual, has been served as a reservoir of germplasm for soybean, G. max (L.) Merr., cultivar improvement. This study describes the levels and distribution of genetic variation within and among 22 Korean populations of G. soja using starch gel electrophoresis. The species maintains very similar levels of genetic variability within populations observed in most other annuals. At the population level, the mean percent of polymorphic loci (P) was 32.6%, mean number of allele per locus (A) was 1.32, and mean expected heterozygosity (He) was 0.112. In addition, total genetic diversity (HT) calculated only for polymorphic loci was 0.347. However, significant differences in allele frequencies among populations were found for all loci (P<0.001 in each case) and, on average, about 70% of the total variation in the species is common to all populations. Indirects estimate of the number of migrants per generation (Nm=0.58, calculated from mean GST) indicates that gene flow is low among Korean populations of the species. In addition, analysis of fixation indices revealed a substantial heterozygote deficiency in most populations and at all loci. This indicates that most populations sampled may have been substructed largely due to inbreeding (predominantly selfing) and restricted gene flow, coupled with founder effect and genetic drift. Considering a high genetic divergence among populations, it is recommended that several Korean populations of the species should be preserved, especially such as populations in the eastern and southeastern Korean peninsula with high variation.
