This study was carried out to provide the basic data for an identifying system for Iris species distributed in Korean market from complete analysing of genetic relationship between three native Iris species and one cultivar bred from the native Iris plant. RAPD analysis of genetic relationship among 4 Irises was possible. According to the RAPD analysis, they were divided into two groups. Among 4 Irises used in this study, Iris laevigata 'Veriegata', Iris laevigata and Iris setosa were classified into the same group since they had many similarities even though the habitat of Iris laevigata in Korean peninsular is restricted mainly in the south and Iris setosa is naturally inhabited in the northern part of Kangwondo. The value for the dissimilarity index of Iris laevigata and Iris laevigata ‘Veriegata’ was 6.757. The value for the dissimilarity index of Iris laevigata and Iris dichotoma was 95.000, so that they were genetically the farthest among them since the genetic relationship between two species are separated far if the value of the dissimilarity index is close to 100.

As the international society becomes more and more open, the international marine transportation demand is growing. And the growth of international tour demands and the developments of new passenger ship routes make the role of passenger terminals crucial. In this context this study analyzes and compares the terminals of Korea and Japan and defines design criteria for the construction of a passenger terminal. As a result of this study, it is proposed that an urban context, an architectural type and spatial characteristics be taken into account for the construction cf a passenger terminal. The ultimate purpose cf this study is to build a future-oriented international passenger terminal based on the result of this study, which will lead the ocean culture.

For a long time, genetic algorithms have been recognized as a new method to solve difficult and complex problems and the performance of genetic algorithms depends on genetic operators, especially crossover operator. Various problems like the traveling salesman problem, the transportation problem or the job shop problem, in logistics engineering can be modeled as a sequencing problem This paper proposes modified genetic crossover operators to be used at various sequencing problems and uses the traveling salesman problem to be applied to a real world problem like the delivery problem and the vehicle routing problem as a benchmark problem Because the proposed operators use parental information as well as network information, they could show better efficiency in performance and computation time than conventional operators.

Interspecific hybrids between onion (Allium cepa L.) and green onion (Allium fistulosum L.) were produced using pistillate parents of two male sterile onion (msC1, msC2) and one male sterile green onion line (msF1), and pollen parents of one male fertile

Improving grain yield and quality of japonica rice continues to be a major breeding objective in Korea. In this study we evaluated genetic divergence among four japonica rice cultivars and assessed the relationship between genetic distance and hybrid perf

T. S. Eliot's "Gerontion" (1919) is so ambiguous that it is almost impossible for the reader to escape the labyrinth of interpretations constructed by critics and scholars with regard to various allusions, obscure poetic dictions and phrases, and contentious images and symbols. The purpose of this paper is to pave a clear path through the labyrinth of conflicting theories and interpretations by contrasting and analyzing the labyrinthine ones on Gerontion's phantasmagoric dramatic monologue. The complicated and controversial interpretations of the battle symbolism, "the jew," "house," "Christ the tiger," characters, "knowledge," "History," "tree," "you," "gull," "the Trades," etc., are traced without bias or ambiguity. Gerontion meditates on depraved transubstantiation, the devouring Christ the tiger, History compared to Satan or a prostitute, and humanity annihilated into atomic fragments. Gerontion also evokes a variety of symbols of the collapse of Western Civilization. He, as a character, embodies the concept of "dissociation of sensibility," for by the end of the poem, his infirm body disappears and thought alone remains. All these things can be revealed to the reader who passes through the labyrinth of interpretations.
