MHD WAVE ENERGY FLUXES GENERATED FROM CONVECTION ZONES OF LATE TYPE STARS
Moon, Yong-Jae,Yun, Hong-Sik The Korean Astronomical Society 1991 Journal of The Korean Astronomical Society Vol.24 No.2
An attempt has been made to examine the characteristics of acoustic and MHD waves generated in stellar convection zones($4000\;K\;{\leq}\;T_{eff}\;{\leq}\;7000\;K$, $3\;{\leq}\;\log\;g\;{\leq}\;4.5$). With the use of wave generation theories formulated for acoustic waves by Stein (1967), for MHD body waves by Musielak and Rosner (1987, 1988) and for MHD tube waves by Musielak et al.(l989a, 1989b), the energy fluxes are calculated and their dependence on effective temperature, surface gravity and megnetic field strength are analyzed by optimization techniques. In computing magneto-convection models, the effect of magnetic fields on the efficiency of convection has been taking into account by extrapolating it from Yun's sunspot models(1968; 1970). Our study shows that acoustic wave fluxes are dominant in F and G stars, while the MHD waves dominant in K and M stars, and that the MHD wave fluxes vary as $T_{eff}^4{\sim}T_{eff}^7$ in contrast to the acoustic fluxes, as $T_{eff}^{10}$. The gravity dependence, on the other hand, is found to be relatively weak; the acoustic wave fluxes ${\varpropto}\;g^{-0.5}$, the longitudinal tube wave fluxes ${\varpropto}\;g^{0.3}$ and the transverse tube wave fluxes ${\varpropto}\;g^{0.3}$. In the case of the MHD body waves their gravity dependence is found to be nearly negligible. Finally we assesed the computed energy fluxes by comparing them with the observed fluxes $F_{ob}$ of CIV(${\lambda}1549$) lines and soft X-rays for selected main sequence stars. When we scaled the corrected wave fluxes down to $F_{ob}$, it is found that these slopes are almost in line with each other.

Mastoparan B (MPB)는 벌독으로부터 정제된 양친매성α-helical 구조를 취하면서 14개의 아미노산 잔기로 구성된 염기성 항균성 펩타이드로서 여러 가지 생물막과 작용한다. 본 연구에서는 우리 나라 연안의 적조 (HABs, harmful algal blooms)를 일으키는 4종의 적조생물 (Alexandrium tamarense, Chattonella catenatum)에 대한 MPB의 살조효과를 조사하였다. MPB의 4종의 적조생물에 대한 살조효과는 31.3㎍/㎖에서 세포의 lysis또는 ecdysis와 같은 형태로 현미경으로 관찰할 수 있었다. 또한 MPB는 C. marina 및 C. polykridorides에 대해서 A. tamarense와 G. catenatum보다 더욱 강한 살조효과를 나타내었다. 이러한 MPB의 HABs에 대한 살조효과연구는 새로운 살조물질을 개발하기 위한 자료가 될 것으로 생각된다. Mastoparan B (MPB), an antimicrobial cationic peptide isolated from the venom of the hornet Vespa basalis, is a basic amphipathic a-helical peptide composed of fourteen amino acid residues. In this study, we have investigated the algicidal effect of MPB against hatmful algae blooms (HABs) casative Alexandrium tamarense, Chattonella marina, Cochlodinium polykrikoides and Gymnodinium catenatum. The algicidal effect of MPB showed in the concentration of 31.3 ㎍/㎖ to 500 ㎍/㎖ against 4 HAB species and observed cell lysis or cell ecdysis by microscopy. MPB reacted more sensitive to C. marina and C.polykrikoides than A. tamarense and G. catenatum. The algicidal study of MPB against HABs will provides much insight into development of new algicidal substances.

한국어 정보처리를 하기 위해서는 가장 기초기술인 형태소 분석이 이루어져야 한다. 한국어의 용언은 어미의 활용으로 인하여 형태소분석을 상당히 까다롭게 하는 특성을 가지고 있으며, 대부분의 어절을 대상으로 용언의 불규칙 현상이 있는 지를 조사해야 하므로 시스템의 속도를 떨어뜨리게 된다. 따라서 이 논문에서는 용언 불규칙현상을 분류하고 알기 쉽도록 도식화하면, 전체 시스템의 속도를 높이기 위한 새로운 자료구조 도입과 알고리즘을 소개한다. Korean Morphological analysis is basic technic of Korean Information processing. Korean morphological analyzer is complicated because of irregular verbs. In this paper, we suggest analysis, diagram, and algorithm of korean irregular verbs processing. The system becomes very efficient because the number of dictionary accesses is minimized. The system makes easy to analyze unknown words like compound nouns without adding them to the dictionary.

The purpose of this study was to examine teachers' perception of Montessori kindergarten and Montessori daycare centers, view of Montessori classroom management and altitude toward Montessori teaching-learning methods in an effort to provide information on the management of these educational institutes and to help teachers apply Montessori programs in a more ideal manner. The research Questions were posed as below: 1. What differences are there in the way of looking at Montessori education between Montessori kindergarten teachers and Montessori daycare center teachers? 2. What differences are there in arrangement of educational areas in Montessori classroom and activities using teaching aids between Montessori kindergarten teachers and Montessori daycare center teachers? 3. What differences are there in attitude toward teaching-learning methods between Montessori kindergarten teachers and Montessori daycare center teachers? The subjects in this study were 238 teachers who worked at kinder garten and daycare center that offered Montessori education in five cities in Gyeonggi province, including Anyang, Euiwang, Gwacheon, Suweon and Ansan. The instrument used in this study was questionnaires for teacher that were reconstructed to serve the purpose of the study and consisted of 15 items, including nine about their perception of Montessory education, six about classroom arrangement and use of teaching aids, and 15S about teaching-learning attitude. The collected data were analyzed with SPSS program and x2 test and frequency analysis were conducted to make a comparative analysis of the kindergarten and daycare center teachers. The major findings of the study were as follows: First, regarding their view of Montessori education, they thought that programs should be prepared to cater to Korean circumstances, and they called for a wide array of activity programs ta take advantage of teaching aids. As to the frequency of education, the kindergarten teachers offered more frequent education than the daycare centers. Second, as for Montessori classroom arrangement and use of teaching aids, the Montessori kindergartens were better equipped than the Montessori daycare centers. With regard to when teaching equipment was put to use, the kindergartens utilized teaching aids in working class, and the daycare centers harnessed them when young children were engaged in free play. Third, concerning their attitude toward teaching-teaming methods, the teachers looked upon young children as ones who were entitled to make a choice of teaching aids on their own, and they viewed their relationship with preschoolers as one of crucial teaching-learning methods. They observed four or five young children in Montessori class, and the outcome of observation was utilized to get a feedback. As for the form of class, multi-age class was considered to produce the best educational effects, and working was viewed as one of primary teaching-loaming media. As to a supply of teaching aids, the kindergarten teachers presented teaching aids by area, and the daycare centers did it according to child development stage. Concerning what made it hard to observe children, the kindergarten teachers pointed out large class size as the reason, and the daycare centers cited their own insufficient knowledge to draw up an observation record. It's required to cut down on class size, since the Montessori kindergartens and daycare centers found it difficult to offer Montessori instruction properly due to a large number of children, Besides, the Montessori daycare centers were less. equipped with teaching aids than the Montessori kindergartens. If daycare centers are more subsidized, they are expected to be able to trigger a plenty of good interaction between preschoolers and tracking aids, and then that will have a favorable impact on the teaming and development of young children.

요즘 우리 평단은 '시와 리얼리즘'논의로 자못 활기를 띠고 있다. '서정시에서 리얼리즘 실현은 가능한가'하는 문제가 뚜렷한 쟁점으로 부각된 것이다. 필자는 이미 지난해 실천문학사 주관 심포지엄 (〈다시 문제는 리얼리즘이다 〉,1991.9.27)에 제출된 최두석의 「리얼리즘시론 」이 한국근현대시의 사적 전개를 일목요연하게 재구성할 수 있는 과학적인 시연구방법론으로서, 그리고 창작방법론적 전범으로서 얼마나 생산적일 수 있는가에 다소 의문을 제기한 바 있다. 이 논의가 한국근현대시의 주요한 시적 성과물들에 대한 체계적 연구 및 시창작 면에서 새로운 활로를 개척할 수 있으리라는 점은 일정하게 인정하면서도, 자칫 그것이 서정시 특유의 현실반영 방식에 대한 섬세한 고려 없이 시창작의 평판화와 연구의 단선화 경향을 부추김으로써 오히려 소모적인 방향으로 전개될 것을 우려한 때문이다.
