Three species of the genus Centropages(C. calaninus, C. orsinii, and C. sinensis) were newly collected from Korean waters. The Korean specimens were consistent with previous descriptions, but differ in the following characteristics: in C. orsinii male right antennule with spine on dorsoposterior surface of each segment XIII and XIV; distal end of segment XIX with humplike process on dorsal surface; in C. calaninus female long spinelike process on second exopodal segment of leg 5 of reaching 1/2 length of terminal spine on third exopodal segment; in male, first endopodal segment of leg 5 without inner seta; left second exopodal segment serrated on distal margin; and in C. sinensis male distal spine of left second exopodal segment of leg 5 not fused with segment. In this study, key characters for species identification also were provided.

Three Pleuromamma copepods were newly collected from the South Sea of Korea in the summer when the Tsushima Warm Current was strong. They were identified as Pleuromamma abdominalis(Lubbock, 1856), P. indica Wolfenden, 1905, and P. xiphias (Giesbrecht, 1889). Although these species have been reported in world oceans, they were first reported from Korean waters. So far, four species of Pleuromamma (P. borealis Dahl, 1893, P. gracilis Claus, 1863, P. piseki Farran, 1929, and P. robusta (Dahl, 1893)) have been recorded in Korean waters. We provided re-description of these three species insufficiently described by previous authors and key characters for species identification in addition to species hitherto known in Korea.

We propose a new approach to the feature selection for the classification of handwritten characters using two-dimensional(2D) wavelet packet bases. To extract key features of an image data, for the dimension reduction Principal Component Analysis(PCA) has been most frequently used. However PCA relies on the eigenvalue system, it is not only sensitive to outliers and perturbations, but has a tendency to select only global features. Since the important features for the image data are often characterized by local information such as edges and spikes, PCA does not provide good solutions to such problems. Also solving an eigenvalue system usually requires high cost in its computation. In this paper, the original data is transformed with 2D wavelet packet bases and the best discriminant basis is searched, from which relevant features are selected. In contrast to PCA solutions, the fast selection of detailed features as well as global features is possible by virtue of the good properties of wavelets. Experiment results on the recognition rates of PCA and our approach are compared to show the performance of the proposed method.

The taxonomic status and scientific names of Artemisia gmelinii and its allied taxa have long been debated. To provide correct names and taxonomic status, A. gmelinii and its allied taxa were reviewed in this study based on morphological characters. After a comparison of original descriptions and type specimens, the names of A. freyniana f. discolor and A. freyniana f. vestita used in Korea were recognized as A. sacrorum var. sacrorum and A. sacrorum var. incana, respectively, based on the characters of the trichome on the leaf, the geographical distributions, the chromosome numbers, and the existence of a pinule connection on the exine of the pollen. A. iwayomogi, the scientific name misused as A. gmelinii, was combined and newly named A. sacrorum var. iwayomogi (Kitam.) M. S. Park & G. Y. Chung based on its morphological similarity to the A. sacrorum group. A description, illustration, and key for each of the taxa are provided here.

The costumes as an expression system in film are inserted intentionally for a particular purpose. Costumes in film, namely the cinematic dress code, and that in reality are dissimilar in meaning structure. The costumes in film perform a role of a complicated eye-catcher in correlation with the other filmic factors. But the previous studies on the costumes in film are focused on the keywords 'fashion style', 'fashion trend', or 'PPL (product placement)'. In film studies, however, the costumes should be observed from the point of view as semiosis, not as fashion, in other words, from the angle of symbol, icon and index. And the meaning and the process of the communication, which that produce, should be pointed out. It could expose, that costumes play one of the key roles for the developing of narratives and the creating of characters in film. Therefore, this study's aim is to examine the semiosis of costumes in film and to analyse the dress code, dress plot, and dress message in (1990) by Garry Marshall. But this work does not try to indicate the problems of the film-semiotics or to intensify the concept of the semiotic terminology. Thus, this study attempts to approach the theme of costumes in film from the perspective of the semiosis and its meaning process. With this, it has been proved, that semiotic systems are in hiding beyond the conventional forms of cinematic costumes and its natural harmony with characters.

The 3D game graphic technology has become an important factor in the contents field with the game contents development. In particular, game character technology provides a realistic technique and visual pleasure, as well as an intermediate step in the immersion of the game in which the game might create an optical illusion that enables the player to enjoy heroic adventure in the game. The high expression level of characters in 3D games is a key factor in the development process, with details and carefulness of the character setting work [3]. In this paper, we propose a character representative technique applied to mobile games using mathematical model of radiosity energy, spectral radiance model, and ray tracing model method using 3D unity game engine with sensible AI algorithm for game implementation. As a practical application to the game contents, it was found that the projection of the surface in the rendering process and the game simulation might change according to the lighting condition of the game content environment, so that the high quality of game characters was simulated.

Parastenocaris koreana sp. nov. is described based on examination of numerous adult specimens of both sexes from several localities in Korea. Scanning electron micrographs are used to examine intra- and interpopulation variability of micro-characters, in addition to light microscopy. The new species is most closely related to the Japanese P. biwae Miura, 1969, which we redescribe based on newly collected material from the Lake Biwa drainage area. The two species differ in size, relative length of the caudal rami, shape of the anal operculum, shape of the genital double somite, relative length of the inner distal process on the female fifth leg, as well as relative length of the apical setae on the second, third, and fourth legs exopods in both sexes. Detailed examinations of three disjunct populations of P. koreana reveal also some geographical variation, especially in the surface ornamentation of somites, which may indicate some population structuring or even cryptic speciation. Lack of intraspecific variability in the number and position of sensilla on somites, as well as their potential phylogenetic significance, is a novel discovery. Both species examined here belong to the brevipes group, which we redefine to include 20 species from India (including Sri Lanka), Australia, East Asia, Northern Europe, and North America. A key to species of this group is also provided. In order to test the monophyly of the redefined brevipes group with highly disjunct distribution, as well as relationship between different species, a cladistics analysis is performed based on 39 morphological characters and with help of three outgroup taxa. Six equally parsimonious cladograms are generated, all of which show that the ingroup is well defined by at least three synapomorphies. Reconstructed phylogeny questions the previously suggested hypothesis about the origin of this group in South East Asia, with one Australian species showing the most basal position. We speculate that the present distribution of this group may be a combination of ancient vicariance and subsequent dispersal, with a possible origin in the Gondwanaland, in the rift valley between Australia and India.

Since the advent of digital games with hardware development a key component of the game characters are changed to retard the rate at which types of users based on their favorite theory of human proportion. Many popular to gamers in the game according to the change in the retard rate in a unique image of the character. Studies on the head and body proportion are thought that up to now been insufficient. The purpose of this study is to examine a fundamental human proportion that has importance as a molding factor in the game character development, it investigated the characteristics of the game character, and classifying the retard rate of the game character, through the research method of analyzing the results, into the retard rate look for and investigate studying the effect on future game images. Five types of game characters that make up the analysis were analyzed with a unique image, and the more specialized users prefer retard rate, the figurative exaggeration to retard rate than the actual main body. Utilizing a bit exaggerated the difficulties of the character looks relatively small proportion character in the graphic wallpaper increased visibility. The proportion of a game character through the study is considered as a very important factor as the game image in the game development.
