  • Two Atractylodes species, A. japonica Koidz. ex Kitam. (AJ) and A. macrocephala Koidz (AM) were used in this study. AJ population had higher amounts of Sesquiterpenoids and stronger tolerance to root rot but less vigor of root growth than AM population. Two populations (AJ and AM) were crossed to make interspecific hybrid population. A total of 98 lines propagated clonally were selected from a cross of AJ and AM, and evaluated for contents of sesquiterpenoids, atractylon (ATLN) and atractylenolide III (AT3) using high performance liquid chromatography (HPLC), and growth characters such as plant height, stem number and root weight. HPLC profiles of the hybrids were compared with those of parent plants, and it demonstrated the production of introgression hybrid by crossing between AJ and AM. Of 98 clonal lines,10 lines were selected by 10% level based on the growth vigor and tolerance to root rot, and AJM2102-51 line showed the heaviest root weight (117.1 g/plant) among them. A total of 98 hybrid lines contained on average $0.16\;{\pm}\;0.10\;mg/g$ of $AT3,\;2.00\;{\pm}\;1.37\;mg/g$ of ATLN, and $2.16\;{\pm}\;1.40\;mg/g$ of total sesquiterpenoids, showing high coefficients of variation (above 65%). Ten lines having high contents of sesquiterpenoids were selected, and AJM2101-15 had the highest amount (9.83 mg/g) of ATLN, and showed 40.8 g/plant of root weight similar to mean value (39.9 g/plant) of hybrid lines. The result showed that the introgression of both characters of vigorous growth from AM and high sesquiterpenoids content from AJ could be possible to make new hybrid lines by crossing between AJ and AM.

  • We described the scale characteristics of induced hybrids between female red seabream (Pagrus major Temminck et Schlegel) and male black seabream (Acanthopagrus schlegelii Bleeker), and of their parental species. The external scalar morphology of induced hybrids showed intermediate characters compared to those of the parental species. The mean number of primary apical grooves and lateral line scales was $10.5{\pm}2.6$ and $49.5{\pm}0.5$, respectively, in induced hybrids, which also showed intermediate meristic characters compared to those of the parental species (P<0.01). The meristic characters used in this study may be useful parameters for the identification of genotypes of these seabream species.

  • In seven species of Korean Asarum, 44 qualitative and 28 quantitative characters were reviewed taxonomically. Among 44 qualitative characters observed in vegetative and reproductive organs, the states of 27 characters were common in all the seven species. Among 28 quantitative characters, five characters have the same values in all the seven species; the number of cataphyll (2-4), leaf (2), calyx lobe (5), stamen (12) and pistil (6). White spots on adaxial surface of leaf (effectively) distinguished A. maculatum and A. versicolor from the other species. Many long soft hairs on abaxial surface of leaf distinguished A. mandshuricum from other species with short hairs. The glandular hairs on inner surface of calyx tube were divided into 2 types, reflecting the taxonomic relationships between the species: Type 1 has non-stalked glandular hairs (A. maculatum, A. sieboldii and A. sp.), and Type 2 has stalked glandular hairs (A. patens, A. versicolor, A. mandshuricum and A. misandrum). The length, shape, colour of calyx lobe and the extent to which the calyx lobe recurves, as well as the diameter and colour of calyx tube throat, were confirmed to be taxonomically valuable. In the case of glandular hair density on the surface of calyx lobe, A. patens with low density and A. sp. with high density were clearly distinct from all the other species with intermediate hair density. Meanwhile, the stylar protuberance length of A. patens (2.9-3.3 mm) was strikingly different from other species (1.4-2.5 mm). Additionally, further examination of the identities of A. yeonbyeonense and A. yeonbyeonense var. viridiluteolum is required.

  • In order to find useful taxonomic morphological characters, 17 taxa from East-Asia Astragalus and Oxytropis anertii were investigated. In this study, seed coat structure, fruit surface, and fruit anatomical structures were selected to classify the species in Astragalus. As a results, useful morphological and anatomical characters in East-Asia Astragalus were life cycle, leaflet shape, raceme, petal color, seed color, pod shape, absent or present of hairs in pod surface, bent degree of dorsal suture, and thickness of endocarp. Using medicinal sources in China, A. floridus, A. membranaceus, A. membranaceus var. mongholicus and A. tongolensis were formed same group. However, these were not completely consensus in the morphological characters. The other hand, A. koraiensis and A. sikokianus, which have controversial taxonomic issue, have clearly no differences morphological characters each other. Therefore, A. koraiensis, A. sikokianus, and A. bhotanensis should be conducted a comparative study on the DNA sequences and molecular cytology in order to clarify the taxonomic treatments in the near future.

  • This study evaluated the effects of the syllable number(one, two), font type(gothic, myung), color contrast (black on white, white on black), display type(paper, LCD), age(20s, 60s) and character size(2~80pt) on the Korean characters' legibility. Total twenty subjects from two age groups (20s: n=10, 60s: n=10, five male and five female in each group) participated in the legibility test. A target panel was presented in the distance of 50 cm, and subjects conducted a reading tests for, in total, 16 treatment conditions (full combination of syllable number, font type, color contrast and display type). Results showed that two-syllable words revealed better legibility than one-syllable character. The main effects of the age, display type, font type, color contrast, and character size were statistically significant(p<0.01). Paper showed better legibility than LCD, particularly in the 20s and in the character sizes of less than 9pt. Gothic revealed more correct answers than Myung, particularly in the 60s, paper, and white on black conditions. It is expected that these results can provide basic data for the determination of the Korean characters' minimum legible size standards. For example, the minimum legible size for the Gothic and black on white characters presented in the paper should be 5pt for 20s and 1lpt for 60s if the 75% correct reading(3 correct answers in this study) was applied for the legibility criterion.

  • There is a problem with the existing method of selecting the difficulty levels of Hanja characters. Some Hanja characters selected by the existing methods are different from Sino-Korean words used in real life and it is impossible to know how many times the Hanja characters are used. To solve this problem, we measure the difficulty of Hanja characters using the multiple regression analysis with the frequency as the features. Based on the elementary textbooks, FWS and FHU are counted. A questionnaire is written using the two frequencies and stroke together to answer the appropriate timing of learning the Hanja characters and use them as target variables for regression. Use stepwise regression to select the appropriate features and perform multiple linear regression. The R2 score of the model was 0.1105 and the RMSE was 0.1105.

  • The purpose of this study was to evaluate the legibility of one-syllable Korean characters with the participation of sixteen subjects. The experiment considered nine factors including age (young and old), gender (male and female), illuminance (150lx and 600lx), viewing distance (50cm and 200cm), material type (paper and LCD), typeface (Ming and Gothic), thickness (plain and bold), color contrast (black letter/white background and white letter/black background), and complexity (simple, complex, and number) to examine main effects with a $2^{6-3}\times3$ fractional factorial design. The dependent variables were minimum character size of 100% correctness, maximum character size of 0% correctness, and minimum character size of comfortable reading preference. The results of analysis of variance (ANOVA) revealed that age, illuminance, viewing distance and complexity were significant for all dependent variables, except gender which was significant only for the minimum character size of comfortable reading preference. In general, the young could see twofold smaller size letters than the elderly. The subjects could see smaller sized letters with the illuminance of 600lx and viewing distance of 50cm than 150lx and 200cm, respectively and also with numbers, simple characters, and complex characters in that order. The findings of this study could be characterized about the legibility of Korean characters and be good resources for developing its standard.

  • The purpose of this study is to establish how main characters' mental states are expressed through costumes and makeup by understanding and analyzing the relationship between the costumes and the makeup in the movie "Anna Karenina" and to compare the 19th century Russian costumes. The study methods are a literature review and an empirical case study. The results are as follows. First, the costumes in "Anna Karenina" are a mixture of late crinoline and early bustle style in general. However, the costumes were altered after the actress's movements and acting were considered. Regarding colors, Anna wears a lavender robe as the virtuous wife, a wine-colored robe for love and death, and a white robe for innocence, thus reflecting her mental states; through the colors, her changes of mental state are expressed. Second, the costumes of Alexei Vronsky, are similar in style and colors to those of mid-late 19th century Russian military uniforms. White, blue and black costume colors are used to describe his situations and emotional changes. Third, Alexei Karenin wears 19th century costumes of dark and achromatic colors without decorations, representing his conservative, authoritative character. However, he showshis rage with a wine and red-colored costume at the end of the movie. Fourth, regarding the makeup in the movie, Anna wears makeup of a soft pink-gold color influenced by 19th century naturalism. Male characters express their characteristics with their beards and hair styles. Vronsky's Hollywood mustaches and wavy blonde hair show his charm, and Karenin's chin curtain beard and bald head reveal his conservative character. The costumes of the three main characters in the movie are not very different from 19th century style in general, but mental states and situations are expressed through accessories, and colors maximize all of the effects. Through this research, it is illustrated that the costumes and makeup in a movie can not only express characters' emotional changes but also show the relationships between the characters in different scenes.

  • In "A Good Man Is Hard to Find," Flannery O'Connor describes a striking journey of a family, in which all the members dramatically get killed. Through the tragic death of Bailey's family, O'Connor evokes the reader to think about life and the life after death. Growing up in the communities of Catholicism and Protestantism, O'Connor herself had agonized with the same question between the two types of Christian belief throughout her life. In the story, O'Connor embodies her anguish with the major characters and questions the reader about the meaning of Christian salvation. More specifically, Bailey's family represent the people who get lost in life. They live without any direction and purpose. Red Sammy and his wife, on the other hand, provide travellers with rest, food, and the necessaries. The Tower is a shelter of travellers in life; however, it is not everlasting but temporary. The Misfit, exemplifying religious stragglers, has been completely frustrated with the variance of Christian salvation theories, and no longer practices the religion but knows enough to justify his cruel behaviors. Finally, the grandmother is the manipulator and opportunist of the religion. All those characters are fragments of human characters and their life - obscene and transitory. In the story, there is little God's grace on the surface even though the writer claims "all my stories are about the action of grace." Nonetheless, the reader should be able to identify with those characters because they are the mirror images of themselves. While visualizing the characters, O'Connor wants the reader to have a moment to think about the "Righteousness," and ultimately to seek out God's grace that she essentially wishes to show the reader. Instead of showing God's grace directly, O'Connor ultimately leads the reader to consider about God and the grace as she/he reads the work.

  • For discrimination the origins and the commercial herb medicines of three Angelicae Radixes (Danggui), anatomical characters of leaves, petioles, and root cross-section were investigated and those were compared each other. The key for discrimination of these herb medicines was made by below simple characters: development of periderm, absent and present of collenchyma under the periderm, and distribution of latex tube in cortex. The result of discrimination for the commercial herb medicines based on the discrimination key, Angelicae gjgantis Radix (Angelica Gigas Root), Angelicae Radix (Japanese Angelica Root), and Radix Angelicae Sinensis (Danggui) were correctly identified for Angelica gigas Nakai, A acutiloba Kitagawa, and Angelica sinensis (Oliv.) Diels., respectively. Consequently, anatomical characters could be utilized for useful method to discriminate three Angelicae Radixes (Danggui).
