A species of moss (Musci) is observed on the Matanuska Glacier of Alaska in the middle of summer. The life cycle of the moss is perfectly observed. This is very rare and special because the environment is completely glacial and barren of plants. Matanuska is a gigantic glacier formed about 18,000 years ago in the Palmer region near Anchorage. It has a dimension of 27 miles in length and 4 miles in width. The glacier is located in the region between Anchorage and Mount McKinley. This huge glacier carved the Matanuska valley thousands of years ago. The mighty glacier also forms the Matanuska River. The summer weather is very changeable throughout the day: warm, cold, sunshiny, windy, cloudy, rainy, snowy, foggy, etc. The Arctic clouds move very quickly and create variable climates. So there are four seasons even in one day during the summer period of this region.

1. This study was made on the flora of bryophytes on Mt. Kwanak, which is situated ($37^{\circ}$30' N. Lat. $127^{\circ}$O'E. Long) to the south of Seoul area. 2. The bryophytic flora of this mountain consists of the following elements. 1) Holarctic elem, Musci………16 species (25.0%), Hepaticae………4 species (28.6%). 2) North Pacific elem. M.………1 species (1.56%), H………O. 3) Cosmopolitan elem. M………10 species (15.65%), H………1 species (7.1%). 4) East-Asiatic elem. M………16 species (25%), H.………4 species (28.6%). 5) Tropical elem. M.………3 species (4.68%), H.………3 species (21.4%). 6) Japane-Korean elem. M.………17 species (26.56%), H.………2 species (14.3%). 7) Endemic elem. M.………1 species (1.56%), H.………O. 3. In the list of bryophytes of Mt. Kwanak, 62 species, 1 variety and 1 subspecies belonging to 47 genera for Musci and 12 species 2 subspecies belonging to 10 genera for Hepaticae were enumerated. Of these the following 5 species are new to Korean flora. 1) Macromitrium japonicum D.M. 2) Entodon arenosus Okam. 3) E. okamurae Broth. 4) Gollania ruginosa (Mitt.) Broth. 5) Temnona birmensis (St.) Hatt.

In this paper, we evaluate and compare the performance of speech/music discrimination based on various feature parameters and classifiers. As for feature parameters, we consider High Zero Crossing Rate Ratio (HZCRR), Low Short Time Energy Ratio (LSTER), Spectral Flux (SF), Line Spectral Pair (LSP) distance, entropy and dynamism. We also examine three classifiers: k Nearest Neighbor (k-NN), Gaussian Mixure Model (GMM), and Hidden Markov Model (HMM). According to our experiments, LSP distance and phoneme-recognizer-based feature set (entropy and dunamism) show good performance, while performance differences due to different classifiers are not significant. When all the six feature parameters are employed, average speech/music discrimination accuracy up to 96.6% is achieved.

The purpose of this study is to examine a distinctive feature and meaning of Reggae fashion and to establish a form of design on the basis of the Reggae style appeared in the 1990s. For the study, we review a formative background and stream of the Reggae fashion. And then, characteristics of the Reggae fashion is clarified through analyzing street fashion and High-fashion. The result of the analysis demonstrates that the Reggae fashion as a general term of the fashion style is connected to the Reggae musci emerged from Such socio-cultural changes as the tendency of the anti-fashion , the influence of the Afro-fashion , and the popularity of the Reggae music. The reggae fashion has been altered in terms of its style with the lapse of time-Rastafaran style, Raggnuffins and Bhangra style, Hip-hop Reggae style. The Reggae fashion emerged in the 1990s falls into three styles ; Afro-Reggae style, Feminine Reggae style, and Sporty Reggae style. The above mentioned results demonstrate that the design of Reggae fashion targets fro a youth in one's early 20s following a tendency in the 1990s and the 2000s. The design concept represents Romantic Reggae.

This study is to provide basic data on ecology and morpho-pedo milieu by analyzing diatom and grain size of Mt. Jeombong forest wetland. Sample was collected from 6 points and named sample 943, 932, 885, 881A, 881b, 849. Sample 934 could not identify diatom, and the soil layer was colluvium deposited by mass-movement process. Layer of sample 932 was developed in the lower velocity environment, and presence frequence of complete diatom was very low. Hydrological situation of sample 855 was analysed in oligosaprobien environments. Sample 881A was meso-saprobic environments, velocity was slow area that inhabit musci bryopsida and sphaerocarpus. Sample 881B was acidic wetland in oligosaprobien environments. Sample 849 was analysed in oligosaprobien environments. The results of soil and diatom analysis are well reflect on wet environments of mountain wetlands and also it will expected to be in the help of environmental changes study of mountain wetlands.

본 논문에서는 수정된 MUSIC 도래 방향 추정 알고리즘에 대해서 연구 하였다. 수정된 MUSIC 알고리즘은 특이 값 행렬과 베이즈 방법을 적용시켜 공 분산행렬을 최적화 시키고 가중치를 갱신하여 원하는 신호를 추정하는 방법이다. 그리고 MUSCI 알고리즘의 신호 부 공간 방법을 적용시켜 원하는 신호를 정확히 추정하였다. 무상관 신호가 수신 시스템에 입사하면 기존의 MUSIC알고리즘으로 원하는 신호를 추정 할 수 있다. 그러나 일반적으로 수신 시스템에는 상관성 신호가 입사하므로 기존의 MUSIC알고리즘으로 원하는 도래 방향 신호를 추정할 수 있는 능력이 현저히 떨어진다. 모의실험을 통해서 상관성 신호인 경우에 본 연구에서 제안된 MUSIC알고리즘과 기존의 MUSIC알고리즘의 성능을 비교 분석한다.
