  • 대극과 대극속 Anthacantha절의 한계와 근연 분류군과의 유연 관계를 규명하기 위해 Anthacantha절에 속한 8종과 근연 분류군을 포함하여 총 16종의 종자를 광학 및 주사전자현미경으로 연구하였다. 측정된 형질 중 6가지 정성형질만을 이용한 수리분석을 바탕으로 3가지 유형으로 구분되었다. Type I (sect. Anthacan 능선 주변에는 결절이 없이 표면이 매끈한 특징을 가진다. Type II (sect. Medusae+sect. Treisia-1군)는 사각형태로 배능선 주변에 돌출된 세포가 발달되어 있으며 표면에 결절이 있는 특징을 가진다. Type III (sect. Treisia-2군)는 전체적인 형태는 난형이며 배능선 주변에 돌출된 세포가 발달되어 Type II에 가까우나 세포표면에 종피세포가 여러 개 모여 솟아올라있어 Type I, II 에는 없는 특징을 보여준다. 본 연구를 통해 Anthacantha절에 속한 종과 Meleuphorbia절에 속한 종은 종자형태의 형질이 매우 유사하여 유연관계가 깊은 것으로 생각되며, 기존의 분자적, 화분분류학적 연구의 결과와 잘 일치하는 양상을 보였다. 또한 Treisia절과 Medusae절에 속하는 분류군은 종자 형태적으로 Anthacantha절의 종들과 차이를 보이고 있어 이들과는 상대적으로 유연관계가 먼 것으로 추정되며 이와 같은 결과는 최근에 수행된 분자적 연구의 결과와는 상반된 양상으로 나타났다.

  • Typology of religious organization is a useful analysis from the stand point of sociology of region. A study on the change of type of religious organization according to typology is a academic responsibility. This study can also make a religion prepare theoretical shape for the future of the religion. Although Daesoonjinrihoe now becomes a established sect, Daesoonjinrihoe should retain characteristics as a alternative sect. This feature as a alternative sect is an important identity of Daesoonjinrihoe which was established to criticize and overcome established sect. Dotongjingyeong is an ideal world of Daesoonjinrihoe. The foundation of Dotongjingyeong as an ideal world is essential value and reason of existence of Daesoonjinrihoe. For this reason, Daesoon jinrihoe should not just maintain its position but lead to reach the Dotongjingyeong here and now. Dotongjingyeong which should be built here and now is beyond Daesoonjinrihoe as a religious organization, because Dotongjingyeong is new heaven and new earth. Daesoonjinrihoe should put an guard against trial and error through change of type. Otherwise, Daesoonjinrihoe can not retain characteristics as an alternative sector. Now Daesoonjinrihoe may be at a revolutionary turning point for the foundation of Dotongjingyeong.

  • We report meiotic chromosome numbers of three taxa in Carex sect. Mitratae in Korea: Carex breviculmis R. Br. (n = 32II, 33II, 34II), C. polyschoena H. Lév. & Vaniot (n = 37II, 38II), and C. sabynensis Less. ex Kunth (n = 27II). Section Mitratae is one of the most species-rich Asian groups in Carex, comprising approximately 45-80 taxa. Twenty-seven of these occur in Korea, and they are some of the most challenging taxa to identify due to their obscure and inconspicuous diagnostic characters. Including the counts reported here, half of the native Korean sect. Mitratae chromosome numbers have been documented. Their haploid chromosome numbers range from n = 10 to n = 40, and many exhibit variations in the numbers counted within a taxon. These variations, along with the overall significant variation in sect. Mitratae, suggest that dynamic chromosome activity may be related to the high species diversity of Carex.

  • An anthecological study of Tilia in Korea was undertaken for six native and one introduced species. Flowers are protoandrous with anther and stigma opening during the day-time in section(sect) Anastraea and the night-time in sect Astrophilyra. Nectar production was coincided with anther and stigma opening. It is revealed that the primary role of floral bracts was attracting pollinators especially in sect Astrophilyra. The peak of stamen and stigma function, and the production of nectar and odor were closely related with pollinator attraction. Forthy-three species of insects in 30 families were identified for the pollination studies; bees were the most commonly observed visitors in sect Anastraea, while moths were the primary visitors in sect Astrophilyra. Pollination study indicate that it is section specific. But within a section, pollination is not species specific thus interspecific hybridization occurs.

  • Carex splendentissima U. Kang & J. M. Chung, endemic to the Korean peninsula, is characterized by staminate terminal spikes and glabrous elliptic perigynia. Based on its broad leaves, androgynous spikes, and tri-stigmatic features, the species has been placed in Carex sect. Siderostictae Franch. ex Ohwi, an East Asian section and a basal group in the genus. To clarify the monophyly and phylogenetic position of the species, a molecular study using the internal transcribed spacer region of nuclear ribosomal DNA and chloroplast DNA (trnL-F) data was conducted. The DNA sequence data of ten taxa in sect. Siderostictae and closely related taxa (two taxa in sect. Surculosae) with outgroups were analyzed based on maximum parsimony and maximum likelihood (ML) criteria. In the analyses, C. splendentissima was monophyletic and placed within the Siderostictae clade (sect. Siderostictae + two species of sect. Surculosae), forming a clade with C. ciliatomarginata and C. pachygyna (endemic to Japan). The clade (C. splendentissima + C. ciliatomarginata + C. pachygyna) shows evidence of diploidy. Furthermore, C. splendentissima is a sister to C. ciliatomarginata in the ML tree, and the two taxa have staminate terminal spikes. This study also updates the distribution of C. splendentissima and provides keys to the four Korean taxa in sect. Siderostictae. To conserve the endemic species C. splendentissima, further research on its genetic and ecological features should be conducted at the population level.

  • The achene morphology of 21 taxa of Persicaria sect. Cephalophilon including the related taxa of Koenigia (Polygonaceae) was examined using stereo microscopy and scanning electron microscopy to evaluate its diagnostic values and taxonomic implications. The outlines of achene were narrowly ovoid to broadly ovoid in general, and elliptic achenes were observed in Koenigia taxa, with the achene shape being biconvex or trigonous. The size of the P. sect. Cephalophilon taxa ranged from $0.93-3.55{\times}0.80-2.31mm$ and the size of examined Koenigia taxa ranged from $1.10-1.84{\times}0.79-1.02mm$. The smallest achenes in P. sect. Cephalophilon were observed in P. humilis and the largest achenes were found in P. chinensis var. chinensis. Furthermore, infraspecific taxa of P. chinensis had relatively large achenes compared to other taxa within the section. Most taxa of P. sect. Cephalophilon had dull achenes, while four taxa had glossy achenes (P. capitata, P. runcinata var. runcinata, P. runcinata var. sinensis, and P. sinuata). Four types of surface patterns (smooth, tubercles, small pits, and irregular ridge) were observed, and the tubercles were divided into two subtypes according to the grouping and distribution pattern. The achene morphology of P. sect. Cephalophilon is described and compared, and its taxonomic implications are also discussed.

  • This study examines the characteristics of 45 sects of seven new aboriginal religious groups in Korea including Jeungsan sect, Tangun sect, Soowoon sect, Won Buddhism, Bongnam sect, Gahksedo sect, Shamanism sect through field study and various documents. The purpose of the study is to elucidate how their religious ideas are reflected in their ceremonial costumes and what characteritics and underlying meanings these costumes have, and I reached the following conclusions 1. The new religious groups in Korea modified or mixed the designs or names of existing outfits to convey their ideas or beliefs in their costumes. 2. The costumes of new religious groups turned out to have certain characteristics in common: they all reflected the times, Korean tradition, ancestor worship. 3. I looked at the symbolicity, names, and types of the outfit, and their color scheme to establish their structural characteristics, and it turned out that they an symbolized the creeds and ideas of each religion. The names of the costumes such as Way-Robe, Law-Robe, and Ceremony-Robe, for instance, had to do with Buddhism Taoism, and Confucianism. The most common type of costume consisted of traditional hanbok top, pant, robe, and some type of headpiece for men, and hanbok top and, skirt for women, and if women were to wear a robe, it usually meant the sect believed in sexual equality. There was also a tendency to simplify or minimize the dress code, which seems to indicate that the sect was trying to adapt itself to, the times. The most common type of the outer garment for men was a robe with narrow sleeves, straight lapel, and no slits, and a robe with wide sleeves, straight lapel, and slits for women. The color scheme of the costumes included blue, white, yellow, red, and black, reflecting the influence of the Yin-Yang and Five Elements idea and traditional preference for white of Koreans. 4. These religious costumes were worn at various ceremonies, ritual, and various anniversary services for the master and other dignitaries of the sect to render greater piety to those gatherings, to distinguish the sect from other religious groups, to clarify the meaning of the ceremony, and to heighten the devout feelings of the participants. Thus, the structure (the symbolicity, names, and types of the outfit, and their color scheme) and religious background of the costumes of the new aboriginal religious groups in Korea turned out to have inherited and mixed various element of traditional Korean outfit and those of existing religions to symbolize their religious ideas. Many religions in and fall, and each has its own dress codes, and I hope this study provides a framework and data for other researchers and leaders of new religious groups that will emerge in the future.
