Two new species of Myrmica from Korea are described. M. koreana belongs to the schencki species-group of Myrmica and is most similar to M. schencki. It is possibly endemic to the Korean Peninsula. M. hyungokae belongs to the lobicornis-group and is most similar to M. jessensis. It has some characters normally associated with social parasites but it is probably a free-living species. Both new species were clearly separated from their nearest relatives on subjective characters (shape, sculpture etc.) and this was confirmed by discriminant analysis of the morphometrics.

The genus Eucephalobus Steiner, 1936, belonging to the family Cephalobidae Filipjev, 1934 (Cephalobomorpha), represents a group of bacterial feeding nematodes. Although this group is cosmopolitan and species-rich, only two species have been reported from South Korea. Eucephalobus iaculocaudatus Bostrom and Holovachov, 2011 was collected from natural forest in Chungcheongbuk-do, South Korea. This species shows typical morphological characters of the genus Eucephalobus, including a bicornuate labial probolae, cephalic probolae absent and three lateral incisures. However, E. iaculocaudatus is distinguished from other Eucephalobus species by conoid tail with a harpoon-shape mucro in female and ragged mucro in male. In this study, detailed morphological characters and morphometrics of E. iaculocaudatus are described and illustrated based on optical microscopy.

This paper introduces a new motion-synthesis technique for animating multiple characters. At a high level, we introduce a hub-sub-control-point scheme that automatically generates many different spline curves from a user scribble. Then, each spline curve becomes a trajectory along which a 3D character moves. Based on the given curves, our algorithm synthesizes motions using a cyclic motion. In this process, space-time warp curves, which are time-warp curves, are embedded in the 3D environment to control the speed of the motions. Since the space-time warp curve represents a trajectory over the time domain, it enables us to verify whether the trajectory causes any collisions between characters by simply checking whether two space-time warp curves intersect. In addition, it is possible to edit space-time warp curves at run time to change the speed of the characters. We use several experiments to demonstrate that the proposed algorithm can efficiently synthesize a group of character motions. Our method creates collision-avoiding trajectories ten times faster than those created manually.

A transitive permutation representation of a group G is said to be multiplicity-free if all of its irreducible constituents are distinct. The character corresponding to the action is called the permutation character, given by $(1_H)^G$, where H is the stabilizer of a point. Multiplicity-free permutation characters are of interest in the study of centralizer algebras and distance-transitive graphs, and all finite simple groups are known to have such characters. In this article, we extend to the alternating groups the result of J. Saxl who determined the multiplicity-free permutation representations of the symmetric groups. We classify all subgroups H for which $(1_H)^An, n > 18$, is multiplicity-free.

This paper focuses on the aesthetic ideology and aesthetic style embodied in the work of 'Blue is the Warmest Color' to dissect it and examine the identity and construction of identity as a minority group in a postmodern context. Blue is the Warmest Color is a film that focuses on homosexual emotions in adolescent development, showing the budding love and emotional orientation of a 15-year-old girl's adolescence, and the ecstsy and torment that comes with an awakened consciousness. The evolutionary process of the characters' emotional orientations is dissected, pointing out that the central theme of the film is the concern for fluid identity and self-identity. Through the narrative and the setting of the characters' emotional patterns and the "Body Writing" of women, this paper further examine the typical variability and fragmentation of postmodern identity, and interpret in detail the content, messages and effects of the characters' dialogues in the film to illustrate the way in which the work expresses class and identity differences. The research method is based on textual analysis and theoretical research.

Prunus cerasifera, P. domestica 및 P. salicina에서 기원된 자두 53 종 또는 품종으로 부터 27 형태형질의 특성을 조사하여 품종 동정에 필요한 기초자료를 제공하고, 그들간의 분류적 관계를 알아보기 위하여 주성분분석 및 집괴분석을 실시하였다. 조사된 형태형질 중 잎의 크기, 잎의 형태 및 엽내 털 발생정도 등이 자 두아속 식물의 동정 및 분류적 관계 해석에 있어서 상당히 유용하게 이용될 수 있을 것으로 단되었으며, 잎의 길이, 엽병 길이, 밀선수, 형, 엽저, 만개기 등은 P. domestica계 자두와 P. salicina계 자두간에 명확한 차이를 나타내었다. 또한 주성분분석 득점치를 이용한 비가 평균결합법에 의한 집괴분석 결과 53개 분류 군들은 평균거리 1.0을 기준으로 할 때 P. alicina-P. cerasifera 표현군, P. domestica 표현군 및 P. pinosa 표현군 등 3개의 표현군으로 분류될 수 있어, 분류군들의 대략적인 분류적 관계 분석이 가능하였다. 그러나 정확한 종군 분류를 위해서는 보다 많은 형태형질의 용이 필요할 것으로 판단되었다.

The number of Asian women immigrants in Korea is getting bigger and it's important to note that their communication problem in Korean causes not only the difficulty of adapting to Korean society but their children's speech-language disorder. To date there is little research on their acoustics characters and articulatory errors. Therefore, this study focuses on acoustic characters and articulatory error patterns of the women immigrants from Japan and Philippine based on the theory of "contrastive analysis". The subjects were 16 Japanese women immigrants(age: 42.5$\pm$4.4) and 14 Philippine women immigrants(age: 31.64$\pm$6.7) and control group consisted of 10 Korean women(age: 28.3$\pm$1.2). Speech and hearing of all subjects and control group were within normal limits. Speech samples were analyzed in a computer using CSL and data analysis was done on FFT widow for F1, F2, F3 of vowels and on wideband spectrogram for VOT of plosives and africatives. The results of this study were like this; For Japanese women immigrants, they had different articulatory patterns of /e/, /a/, /u/, /o/, /$\varepsilon$/, /m/ from those of Koreans and showed articulatory errors on the fortis and aspirated sounds. The reason is Japanese has only two distinctive characters for plosives and affricates; voicing and voiceless. The Philippine women immigrants also showed the same error patterns as the Japanese women immigrants. Especially the errors on aspirated sounds were prominent because their mother tongue has no distinctive characters about aspirated sounds. For vowels, they showed errors of /a/, /o/, /c/.

본 연구는 동료 멘토링을 활용한 수학 수업에서 학생들의 수학적 인성과 수학 학업성취도에 미치는 영향을 분석하는데 목적이 있다. 본 연구 결과 동료 멘토링을 활용한 수학 수업에서 선행 연구들과는 달리 수학적 인성의 하위요소인 존중심, 배려심, 공유심, 개방심 영역에서 멘토 집단과 멘티 집단 사이에 통계적으로 유의미한 차이는 보이지 않았다. 그러나 수학 일기와 학습지 분석을 통해서는 동료 멘토링 수업으로 인한 수학적 인성의 변화를 각 하위 요소별로 구체적으로 확인해 볼 수 있었고, 학생들의 수학 학업성취도에도 통계적으로 유의한 차이를 보이는 것으로 나타났다. 이러한 결과를 바탕으로 동료 멘토링을 활용한 수업은 학생들의 수학적 인성 함양과 수학 학업성취도 향상에 도움을 주고, 멘토보다는 멘티에게 보다 큰 변화가 있음을 알 수 있었다. 초등 수학 수업에서 동료 멘토링에 대한 다양한 학년 수준에서의 후속 연구를 제언하였다.

This paper proposes a method for constructing the virtual characters adopting the personal body types for the clothing coordination. At first, the method produces the 38 kinds of the Korean 3D body models considering sex, ages and body types, and constructs model DB. We select a model similar to the personal body size from DB and deform the selected model according to body size. The method deforms the model linearly for height 12 items, width 6 items, depth 5 items and round 13 items, and constructs the personal character fitted to the personal body size. The preprocess for model deformation consists of grouping for body part and establishing the feature points. Linear deformation for each group leads us to easy construction of the virtual personal characters. This method has two advantages as follows: 1. Large reduction of man power, cost and time for DB construction of the body 3D models, since the preprocess permits us to effectively use the various body models whose geometrical structures are different, 2 Suitability to Web-based clothing coordination, since the body deformation method is simple and its speed is very high.

엉겅퀴속의 한국 특산종으로 인식되어온 고려엉겅퀴 (Cirsium setidens)와 정영엉겅퀴 (Cirsium chanroenicum) 그리고 동래엉겅퀴 (Cirsium toraiense)를 대상으로 분류군의 한계와 그 실체를 명확히 밝히고자 외부 형태학적 형질을 중심으로 수리분류학적 연구를 수행하였다. 고려엉겅퀴와 정영엉겅퀴는 주요 식별형질인 잎, 화서 및 총포에 관한 29개의 외부 형태학적 형질과 잎에 관한 12개의 주요 식별형질들을 비교 분석한 결과, 거의 구별이 되지 않는 하나의 집단으로 나타났다. 이러한 결과, 한국 특산종인 정영엉겅퀴는 고려엉겅퀴에 포함하는 것이 적절하다고 판단되며, 또한 동래엉겅퀴는 원기재문에 의한 생육지 조사, 기준표본과 표본관 소장 석엽표본 조사 등의 결과, 그 실체를 확인할 수 없었다.
