To obtain basic information on the Korean local com lines a total of 57 lines were selected from 1,000 Korean local collection at Chungnam National University, and classified by principal component analysis, and genetic nature was investigated. There were a great variation in mean values of plant characters of the lines. The mean values of plant characters except for density of kernels varied with types of crossing. All characters except for tasselling dates were reduced in magnitude when selfed, while those characters were increased when topcrossed. The inbreeding depression varied with plant characters and lines. The characters such as yield, kernel weight per ear, ear weight and plant height showed great degree of inbreeding depression. Group I showed high inbreeding depression in such characters as 100 kernel weight, leaf number, plant height and days to tasselling, while group II showed high inbreeding depression in other plant characters. Heterosis of plant characters varied also with lines. The ear weight, kernel weight per ear, yield, 100 kernel weight, and plant height were some of the plant characters showing high heterosis. Group II showed high values of heterosis in such characters as ear length, ear diameter, ear weight, kernel weight per ear, 100 kernel weight and leaf length, while group I was high in heterosis in other plant characters. The degree of homozygosity was highest in ear weight (79.1%) and lowest in ear number per plant (-2.1%). Group II showed higher degree of homozygosity than group I. Correlation coefficients between characters of sibbed and topcrossed lines were positive for all characters. Highly significant correlation coefficients between sibbed and topcrossed lines were obtained especially for characters such as ear number per plant, plant height, leaf length and yield per plot.

By finding two characters of subgroups of the Heisenberg group $H_{27}$ whose induced characters are same, we prove that the Birch and Swinnerton-Dyer conjectures for two elliptic curves corresponding to the characters are equivalent.

Parks [7] showed that there is an one to one correspondence between good pairs of subgroups in G and irreducible monomial characters of G. This provides a useful criterion for a group to be monomial. In this paper, we study relative monomial groups by defining triples in G, and find relationships between the triples and irreducible relative monomial characters.

Among the Chinese Characters originated in Japan, some of them are very ancient in their origin and others come to exist as different forms by being used widely in forged books in Chinese. These Characters can be divided into three groups. First, the Chinese Characters whose forms are different. Most of these are 'hoiui' (회의)character, being made by imitating the forms of the original Chinese Letters. These characters do have meaning but not pronunciation. This is one distinct feature of Chinese Characters originated in Japan. Second, the Chinese Characters whose meaning has been assigned by the Japanese people. These letters can be grouped into two. One is the letters whose meanings are entirely different from original Chinese Characters, and the other is the letters whose meanings are not known although their pronunciations are known. It can be explained that the letters with different forms are made because of the ignorance of letter's existence. Or, the letters were made on purpose in ordoer to be used in different meanings. Third, the Characters with a partial modification of original Chinese Characters. Among the Characters in three groups above, pure Japanese-made Chinese Characters are those in group one and three since those in group two are Chinese Letters whose meanings (or pronunciation) only are Japanese. As a results of detailed investigation of pure Japanese-made Chinese Character in JIS X 0208-1990, the followings are discovered: 1. Pure Japanese-made Chinese Characters are 147 in numbers. 2. The Characters which were originally Chinese but now considered to be Japanese-made are 5 in numbers. Among these letters, 39 Characters are not listed in TaeHanHwaSaJon(Whose fame is well known as the authoritative dictionary of Chinese Characters), 47 Characters are not found in the dictionaries of Chinese Characters compiled in Korea. 3. 14 Characters seem to be Japanese-made Chinese Characters although it cannot be said so with accuracy because of various meanings found in several dictionaries of Chinese Characrters.

In the teaching of Chinese characters, making full use of the phonetic function of phonetic symbols can help learners improve their learning efficiency. The research on the characteristics of phonetic symbols and the rules of their construction is the premise of teaching Chinese characters with phonetic symbols. The phonetic symbols that can accurately prompt the pronunciation of the whole word and the homophone characters that they constitute provide the applicable materials for the teaching of Chinese characters. The split method simply and intuitively reflects the internal relationship among shape, sound and meaning in pictophonetic characters. "The analogy method of homophonic character group" and "the converse method of homophonic character group" are the combination of the function of the sound prompt and the characteristics of the analogy and induction of homophonic character, which can not only help students save the time of memorizing the sound, but also effectively increase the amount of literacy. The quantitative analysis of phonetic symbols and homophone symbols is of great significance to the classification of Chinese characters and the improvement of textbook editing.

This study aimed to develop and propose a Korean character group with the story of Shim Cheong applied as a motif. By borrowing the four stories (a dream of the birth of a child, filial behavior, regeneration and eyesight-gaining) presented in the story of Shim Cheong which has been passed on orally, the study designed the Korean character group and set up types of characters' roles to visualize these other characters seen in the content such as Shim Cheong the heroine, goblins, a baby dragon, Mr. Shim the blind and others. As a next step, the study applied the types to the seven essential types of Vogler's original characters. A process of how to visualize the group of those characters appearing in the story including Shim Cheong the heroine was offered. In particular, the study concentrates on figuring out how to expand and develop the Shim Cheong character to be this image of one of the most popular Korean princess characters. What this study had discussed will contribute to the field of character production when they try to commercialize characters and develop Korean characters with unique Korean features included.

The present study was conducted to evaluate agronomic characters of the soybean germplasm which was collected from the sites covering whole areas of southern Korean peninsula. A total of 2,748 Korean native soybeans was grouped for fruiting period and in this group frequency distribution of the important agronomic characters and relationships among the characters were determined. The results obtained were summarized as follows; The soybean germplasm was comprised of SeoulㆍKyonggi-do 7.5%, Kangwon-do 13.3%, Chungchongbuk-6.6%. Chungchongnam-do 12.3%, Chollabuk-do 10.7%, Chollanam-do 12.6%, Kyongsangbuk-do 20.8%, Kyongsangnam-do 15.3% and Cheju-do 0.6% in number of collections. Frequency distribution of the germplasm for fruiting period was 0.14% in Group I (below 55 days). 1.67% in Group II (56-60 days), 10.58% in (Group III(61-65 days), 23.18% in Group IV(66-70 days), 25.91% in Group V(71-75 days) 19.79% in Group Ⅵ(76-80 days), 15.1% in Group Ⅶ(81-85 days) and 3.6% in Group Ⅷ(over 85 days). The lines over 70 days in fruiting period were as much as 64.4% of germplasm. The fruiting period varied largely from 45 days to 91 days. Fruiting period was positively correlated to seed weight, days to maturity, days to flowering, plant height and number of branches per plant, respectively. While. it was negatively correlated to number of pods, lodging and virus infectivity, repectively, and in particular negative correlation was shown significantly between yield and fruiting period. Average yield was very high as much a 1.389kg/ha in fruiting period Group I, and decreased with increment of fruiting period, 1.400kg/ha in Group II. 1.384kg/ha in Group III. 1,299kg/ha in Group IV, 1,197kg/ha in Group V, 1,117kg/ha in Group Ⅵ, 967kg/ha in Group Ⅶ and 832kg/ha in Group Ⅷ.

Korean local and introduced varieties were classified by the cluster analysis of correlation and taxonomic distance based on nineteen growth characters. 1. Thirty six varieties can be classified into three groups(I, II, III) by WVGM (weighted variable group method) 2. Major characters for classifying cultivars were days to flowering, number of leaves, leaf length, stem diameter and width of midrib: the five characters seemed to be useful in monothetic classification. 3. Korean varieties were similar to oriental, and japanese varieties to taiwan. 4. WVGM was more accurate and meaningful than classification by WPGM (weighted paired group method) and reticulate diagram of correlation. 5. Characteristics of each group: Group I closely related to many leaves, late of maturity and broad leaf type, Group II related to medium leaves, late of maturity and narrow leaf type, Croup 19 related to few leaves, early of maturity and medium leaf type respectively.

Vegetative characters (e.g. habitat, root, ramification and habit of stem, phyllotaxy, leaf sape, shape of leaf margin, shape of division and lobe of division, number of division, thick and texture of leaf and shape of stipule) on 35 species of Asian Geranium were reviewed to discussion propriety of taxonomic character and evolutionary trends. Wilfordii group is characterized by three divided leaf, Farreri group was grown a high altitude, and Maculatum group is grouped by life cycle of anneal. Arrangement state of leaf is alternate type G, tripartitum, G. eriostemon, and G. erianthum is thought the more primitive than the other taxon, and regarded as more advanced group the sibiricum group and pseudosibiricum group which divided of leaf deeply. Shape of leaf, division degree of lobes, shape of leaf margin and number of division are considered a good identification characters because width of change are fixed between population.
