Sweet pepper inbred lines (KNU1003, KNU1006, KNU1007, KNU1009, KNU1015, KNU1017 and KNU2006) developed at Kangwon National University (KNU) through conventional means, inbred lines (5AVS1, 5AVS2, 5AVS3, 5AVS5, 5AVS7 and 5AVS8) collected at Rural Development Administration (RDA) and inbred lines (SP12, SP27 and SP14) derived from anther culture were used as female parents and anther culture derived homozygous lines (SP9, SP10, SP14, SP24, SP25, SP27, SP30, SP32, SP34, SP38, SP43, SP45 and SP51) were used as male parents to produce $F_1$ hybrids. A total of 37 $F_1$ hybrids were evaluated for fruit yield and quality characters in summer season, 2007. Variation in fruit number, fruit weight, fruit yield per plant and fruit volume was observed among the $F_1$ hybrids. Superiority on yield over standard/commercial varieties were differed among $F_1$ hybrids. Hybrid $5AVS8{\times}SP45$ exhibited highest heterosis over Special (16.5%) and Fiesta (24.7%). Fruit quality characters (fruit length, fruit width, pericarp thickness, total soluble solid, fruit shape and fruit color) were varied among the $F_1$ hybrids. Fruit number, fruit weight and fruit volume per plant were correlated with fruit yield. Based on the standard heterosis expressed by the hybrids and quality characters evaluation, $KNU1017{\times}SP27$, $5AVS1{\times}SP43$, $5AVS5{\times}SP27$, $5AVS8{\times}SP45$, $SP12{\times}SP38$ and $SP27{\times}SP25$ hybrids were found to be superior over commercial cultivars and are selected. Inbred lines of these hybrid combinations can be used to produce $F_1$ hybrid seed for commercial production.

There has been a lot of controversy over the claim that ancient characters were engraved on a stone plane collected near the Samsin Mountain in Hadong-gun, and that it was used as an altar based on the contents on the stone. The importance of the role of geoscience in prehistoric petroglyph research was presented through analysis and comparison with representative domestic petroglyphs. First, by examining the geological formation process of the collected stone objects, it proved that prehistoric actions were not applied. Second, as a result of comparative analysis from the viewpoints of human geography and topography with representative petroglyphs in Korea, it is unreasonable to argue that the stone was made for an altar. Third, it is considered that among the ancient characters under debate, the straight line indicates a cleavage of carbonate minerals, and the curved shape results from the growth of lichens. Finally, we propose that reproducing the lines found on the stone was impossible by using ancient techniques, and that there was no trace of any artificial actions applied to the spots considered to be curved characters. As shown in such research cases, the results of petroglyph research will have high reliability, if research by experts in each field continues after the geoscientific basis is secured. In this respect, the contribution of Earth science to cultural assets and archeology is expected to increase in the future.

This study proposed the design of audience characters to increase the interactivity between audiences who enjoy music performances in the metaverse. As a research method, domestic and foreign performance videos were investigated, classified according to genre and scale, and facial expressions, gestures, and tools required for interaction were analyzed. As for the facial expressions of the audience characters in the metaverse performance, the facial expressions of cheers and appreciation were added to the nine facial expressions suggested in previous studies. Gestures were organized into 7 gestures after reviewing the video of the case performance, and new gestures were added that could reflect the interaction characteristics of the audience well. The tool classified and organized various tools found in the surveyed performance video by type, and designed and proposed them appropriately. In addition, the body ratio and shape of the characters were appropriately adjusted so that the audience could interact more naturally. The results of this study are expected to contribute to enhancing interaction among audiences by presenting a basic guide to character design for music performances in the metaverse.

An animation is a tool to represent the consciousness of an author. It is a medium that converts his/her consciousness to time by the means of spaces. Image is the most inherent element among the elements of an animation. Character is the element that has the very core function among the elements of an image because a character is a shape that can deliver a story through various actions and facial expressions. In this context, is a representative satire animation that describes a ranked and unequal human society and selfishness and absurdity of human beings existed in the human society, based on the original work of George Orwell. Therefore, this study aims to study what the work tries to satirize through the meanings and symbols that the characters, animals, and spaces in the work. As a result of the study, it was found that the characters appeared in the work are metaphoric symbols that imply the meanings of each character, not just simple characters or spaces. In the work, the farm is a symbolic space that symbolizes a human world. John, a human being, is described as a dictator in an absolute Russian monarchy who suppresses people. Old Major, a pig, is described as an old pioneer that preaches the appropriation of a revolution while Snow Ball, a pig that follows the Major is described as a naive leader that dreams to establish a real socialist state where everybody lives equal, through successful revolution. Another pig, Napoleon is described as the more greedy dictator than human being. He killed Snow Ball for his private ambition and suppresses and exploits the same race, animals. That is, setting man and various animals in the relation of dominant class and subordinated class, the author generates conflicts among characters. Although the characters pursue an ideal society through revolution, it requires another revolution in the process, which expresses repetitive contradiction of human history in a symbolic and strong way.

A seven-parent half-diallel cross was analyzed for white center, white belly and alkali digestibility value(ADV). The analysis of variences were significant for all characters at 1% level. Both general and specific combining ability were significant for all characters. Non-additive genetic varience predominated for ADV(12hr. treatment) and additive effects were more important than non-additive effects for other characters. With the exception of ADV(12hr. treatment), which showed complete dominance, partial dominance in a negative direction was observed for the other characters. Heritability values were high in all characters. White belly was high positively correlated with white center and ADV.

Twenty seven species of pufferfishes (family Tetraodontidae) have been examined to find their generic characters based on olfactory organ, lateral line system, prickles, body form and color characters of specimens collected in 20 places along the coast of Korea from September, 1989 to July, 1994. Based on nostril shape, the genera of Takifugu, Lagocephalus, Plurancanthus, Spheoides and Feroxodon have two nostrils, and those of Ephippion and Canthigaster have a single nostril or nasal tentacle, while Boesernanichthys, Arothron and Chelonodon have no nostril. In the genera of Lagocephalus, Spheoides, Boesemanichthys, Arothron and Feroxodon have only a single well-developed lateral line on the body, in those of Takifugu and Plurancanthus usually have two lateral lines, and those of Chelonodon and Ephippion have two lateral lines merged on the caudal peduncle. Based on the lateral line system and olfactory organ, genus Canthigaster has different characters from the other genera of the family Tetraodontidae. In Ephippion guttifer, the prickles on the dorsal and lateral of the body are enormously enlarged into plates forming a partial carapace. Of the 22 species which have prickly spines, the genera, Lagocephalus, Takifugu stictonotus and Arothron Stellatus have the larger ventral pricklyy spines than the dorsal ones. In genera Lagocephalus most of the species have prickly spines that coverd both the back and belly, while L. inermis has no prickly spines.

Anatomical features of both leaves and stems of the four mistletoes in Korea (Viscum album var. coloratum, Korthalsella japonica, Loranthus yadoriki, L. tanaka) and of their secondary haustorial structure within several host plants were investigated. Among the four mistletoes, there were diagnostic characters of the anatomy of leaves and stems which enabled us to distinguish the four taxa. Leaves were observed to have three distinct characters including unifacial or bifacial leaves, the number of vascular bundles in the midveins, and the level of development of sclerenchyma cells. There were four diagnostic characters of stems: overall morphology of stems in transverse view, degree of cuticle development, arrangement of vascular bundles, and features of the sclerenchyma and pith. In order to determine secondary haustorial traits, the research focused on the seven host plants of L. yadoriki and on the five host plants of K. japonica. The following features were found to be important: presence or absence of an aerial runner root, the shape of the haustorial strand and flange, the degree of penetration into host tissues, and their development of shaft in transverse view, the development both of secondary haustorial cells and short tracheid in hyphae. Korthalsella japonica and L. yadorki were clearly distinguished by these characters. The secondary haustorial forms in each host were somewhat different, due to varying degrees of development in the strength of the host plants' wood. However, qualitative characters like the final position of the secondary haustorial penetration into host tissues and the development of short tracheid cells were not only affected by the degree of development of the host plants, but also useful for the systematic study.

Video information retrieval has become a very important issue because of the explosive increase in video data from Web content development. Meanwhile, content-based video analysis using visual features has been the main source for video information retrieval and browsing. Content in video can be represented with content-based analysis techniques, which can extract various features from audio-visual data such as frames, shots, colors, texture, or shape. Moreover, similarity between videos can be measured through content-based analysis. However, a movie that is one of typical types of video data is organized by story as well as audio-visual data. This causes a semantic gap between significant information recognized by people and information resulting from content-based analysis, when content-based video analysis using only audio-visual data of low level is applied to information retrieval of movie. The reason for this semantic gap is that the story line for a movie is high level information, with relationships in the content that changes as the movie progresses. Information retrieval related to the story line of a movie cannot be executed by only content-based analysis techniques. A formal model is needed, which can determine relationships among movie contents, or track meaning changes, in order to accurately retrieve the story information. Recently, story-based video analysis techniques have emerged using a social network concept for story information retrieval. These approaches represent a story by using the relationships between characters in a movie, but these approaches have problems. First, they do not express dynamic changes in relationships between characters according to story development. Second, they miss profound information, such as emotions indicating the identities and psychological states of the characters. Emotion is essential to understanding a character's motivation, conflict, and resolution. Third, they do not take account of events and background that contribute to the story. As a result, this paper reviews the importance and weaknesses of previous video analysis methods ranging from content-based approaches to story analysis based on social network. Also, we suggest necessary elements, such as character, background, and events, based on narrative structures introduced in the literature. We extract characters' emotional words from the script of the movie Pretty Woman by using the hierarchical attribute of WordNet, which is an extensive English thesaurus. WordNet offers relationships between words (e.g., synonyms, hypernyms, hyponyms, antonyms). We present a method to visualize the emotional pattern of a character over time. Second, a character's inner nature must be predetermined in order to model a character arc that can depict the character's growth and development. To this end, we analyze the amount of the character's dialogue in the script and track the character's inner nature using social network concepts, such as in-degree (incoming links) and out-degree (outgoing links). Additionally, we propose a method that can track a character's inner nature by tracing indices such as degree, in-degree, and out-degree of the character network in a movie through its progression. Finally, the spatial background where characters meet and where events take place is an important element in the story. We take advantage of the movie script to extracting significant spatial background and suggest a scene map describing spatial arrangements and distances in the movie. Important places where main characters first meet or where they stay during long periods of time can be extracted through this scene map. In view of the aforementioned three elements (character, event, background), we extract a variety of information related to the story and evaluate the performance of the proposed method. We can track story information extracted over time and detect a change in the character's emotion or inner nature, spatial movement, and conflicts and resolutions in the story.

Pollen grains of 19 taxa belonging to 12 genera in 5.families of the Korean gymnosperms were investigated by LM, SEM and TEM, and their morphological characters were described and palynological keys were made for each family. From the taxonomic viewpoint, palynological characters are very available to intergeneric and intrageneric classifications since their distinctive differences in pollen shape, size, condition of surface, sculpture pattern and presence of air bladders and projection except for the intrageneric classification of the genus Pinus since the overlapped characters such as pollen size and sculpture pattern. Pollen grains of Picea koraiensis in the family Pinaceae are distinguished from thc genera Pinus and Abies for the reasons that shape of air bladders are irregular, air bladders are bigger than pollen body, and pollen wall is thin. Compared with the genera Abies and Pinus that have air bladders, Picea koraiensis is closely related to Abies in that pollen body wall become gradually thin from pole of proximal face to air bladder, surface of pollen body is not rough, and pollen size is similar to that of the genus Abies. The presence of ektexine and enexine in proximal face, and the connections of the former to air bladder wall and the latter to distal face were elucidated by the investigation of pollen grains with air bladders through TEM. Endexine of the families of Taxaceae, Taxodiaceae and Cupressaceae was also obse-rved as a pile of laminae. From the observation by SEM, sculpture pattern of air bladder was foveolate with fine pits on surface. Sculpture pattern of air bladder is reticulate under LM, but observed by TEM, it resulted from the transmission of netted structure in air bladder.

Morphological characters of aggregated achenes, and achene and its epidermal microstructures were observed for 7 taxa belonging to the section Adonanthe of subgenus Adonanthe [A. amurensis Regel et Radde, A. bobroviana Sim., A. davidii Franch., A. multiflora Nishikawa et Ko. Ito, A. pseudoamurensis W. T. Wang, A. ramosa Franch. and A. tianschanica (Adolf) Lipsch. ex Bobrov] and for 1 taxon belonging to the section Lophocarpa of subgenus Adonis (A. aestivalis var. parviflora M. Bieb.). The morphological characters such as shape of aggregated achenes, length of aggregated achenes, shape of achene, and recurved type of persistent style were useful in the classification of the subgenera Adonanthe and Adonis, and each species of the series under section Adonanthe. Epidermal microstructures of achene were grouped into three types according to the presence of microwrinkles and their arranged patterns. These microwrinkles were absent in A. amurensis, were of parallel type in A. bobroviana, A. pseudoamurensis, A. ramosa, and A. aestivalis var. parviflora, and were of parallelperpendicular mixed type in A. davidii, A. multiflora, and A. tianschanica. Also, a new key to them was made using morphological characters of their aggregated achenes and achene.
