  • Scirpus L. s.l. of Cyperaceae has been regarded as a monophyletic group, but the taxa of Scirpus s.l. were rearranged into the five independent genera in recent molecular phylogenetic research: Bolboschoenus (Asch.) Palla, Schoenoplectus (Rchb.) Palla, Schoenoplectiella Lye, Scirpus L., and Trichophorum Pers. In this study, we examined the morphological characteristics and presented the delineation of the five genera of Scirpus s.l., including 21 taxa from South Korea. As a result of our investigation and analysis of domestic collections and those from abroad, the each taxon could be identified using key characteristics of the rhizome features; a cross-section of culm; the degree of development and the width of leaves; the shapes of the membranous region of leaf sheath; and the shapes and size of inflorescence, bract, floral scale, and achene. These major characteristics are illustrated and artificial keys are suggested in this study. In addition, we suggest a new combination for an unrecorded taxon of Schoenoplectiella that was discovered in Gangwon-do, Goseong-gun and give it the Korean name, as 'a-do-song-i-go-raeng-i'.

  • This study aims to understand causal relationship among preference factors - preferred design, design image, and design elements-to create interaction between artists and spectators, concerning eating and drinking table decoration which is produced with subjective representation chiefly by virtue of the authors' conceptualization and planning. As an experimental research , face-to-face personal interviews have been made in off-line setting through questionnaires. Acquired information from it has been analyzed, which results are as follows. As harmonious, warm, womanish design image, combination of pink-tone similar colors were preferred. As image adjectives highly related with design preference were 'harmonious and inharmonious' A design factor of 'harmonious' was combination of similar colors, while that of 'inharmonious' was association of mixed colors. It has been found that 'colors' have been an important factor among preference design factors. As above, a new concept for design can be established by using data-based information, along with suggesting a direction for preferred design in the field of eating and drinking table decoration. Furthermore, it will be possible to make a study of new preferred design through evaluation of quantitative spectators in this area. It is expected that such researches could give an opportunity to get satisfactory results from newly experimented designs using quantitative data even in a creative design area, as well as table decoration.

  • Background: Pollination is an ecosystem service of utmost importance for agriculture. In this context, the study aimed to evaluate the pollination service of naturally occurring bees and after densification with colonies of stingless bees (Nannotrigona testceicornis and Tetragonisca angustula) in commercial strawberry plantation. The study was carried out in the four seasons of the year and under two experimental conditions: natural pollination (NP) and pollination under bee densification. The supply of flowers and bee density were estimated. For bee densification, four boxes of colonies of Iraí bees and four of Jataí bees were placed near the strawberry plantation. Five treatments were established for each condition, considering NP and pollination with bee densification on different days from flower anthesis, ranging from the 1st to the 5th day. Fruits were harvested, quantified, and submitted to evaluations to determine biometry, degree of deformity, and percentage of fertilized achenes. Results: There was a higher density in summer compared to other seasons in both conditions evaluated. The weight was greater (20.19 g) when fruits were pollinated on the first day after floral anthesis under pollination conditions with bee densification. It was observed that free pollination provided fruits with greater a greater of deformation of flowers on the fourth and fifth day after anthesis. However, when bee density became higher, the greatest degree of deformity was observed only in fifth-day fruits. The densification with stingless bees provided a 50% increase in the number of bees present on strawberry plants in summer and also a 15% increase in fruit weight and the occurrence of a lower degree of fruit deformity. Conclusions: Density with stingless bees provided a 50% increase in the number of bees present on strawberry plant in the summer, with an improvement in fruit quality and aggregate commercial value, providing a 15% increase in fruit weight and a lower degree of deformity under the conditions of densification of Iraí (N. testceicornis) and Jataí (T. angustula) bees. Under the evaluated conditions, the introduction of stingless bee boxes in the summer is recommended.

  • This study was conducted to investigate the flora of Sonjukdo Island(Yeosu-si), Korea. From results of four field surveys from April 2023 to October 2023, we identified 483 total taxa, representing 440 species, seven subspecies, 35 varieties, and one hybrid. They were placed in 322 genera and 109 families, including 249 taxa newly recorded in this study. Among them, four taxa were endemic to Korea, four taxa were IUCN red list plants, and 22 taxa were climate sensitive indicator plants. Floristic target plants amounted to 99 taxa, including two taxa of grade IV, 41 taxa of grade III, 10 taxa of grade II, and 46 taxa of grade I. A total of 54 taxa of alien plants were identified, with a Naturalized Index of 11.2% and an Urbanization Index of 13.8%. Three plants disturbed the ecosystem. The flora of this surveyed area belongs to the south-coast province among floral provinces of the Korean Peninsula. Our results provide basic data on vascular plants flora, plant species diversity, and distributional changes.

  • Rapid changes in the flora of exotic species are ecological problems that cause the alteration of national and regional biota. The purpose of this study is to identify the reality of neophyte flora currently inhabiting in Korea. Having analyzed a total of 151 studies published up until 2016, we found the qualitative and quantitative gaps among the preceding studies due to the lack of rigorousness on the application of the spatial and temporal level of exotic species and academic terminology. In this study, the neophyte is defined as the flora introduced temporarily after the Enlightenment in Korea (late 19th century) and spatially in the Eastern Asiatic Province of the Takhtajan's floral region instead of a country boundary. A total of 326 taxa of 184 genera of 39 families were identified and analyzed for their distributional origin and habitat characteristics. Approximately 87% (285 taxa) was a component of the single-layered herb vegetation, and a total of 211 taxa originated from Europe and North America which are the same temperate biome as Korea. The wetland vegetation components were much fewer with 21 taxa, but they included a large number of invasive alien species that caused critical deterioration in the habitat structure and function of aquatic ecosystems. Ecological approaches to exotic species categories such as Ephemerophyten and Apophyten have emerged.

  • This study carried out palynological analysis and seismic interpretation to establish a stratigraphic and environmental reconstruction mainly based on fossil palynomorphs and seismic reflection data correlated with the oil exploation well (BP-1) located in the Sora Sub-basin. There were frequent environmental and floral changes due to sea level change in the Sora Sub-basin. The palynomorph assemblages found in the well sediments enabled paleoecological zonation of the well sediment sequence resulting in 4 zones: Ecozone III, Ecozone IV, Ecozone V, Ecozone VI. Index fossils among palynomorphs indicate geological ages of the units within the well ranging from Eocene to Pleistocene, and paleoenvironment varies from freshwater to inner neritic marine. Previous studies suggest that the marine deposits were slightly different in stratigraphic range from well to well. It is considered the difference is credited to geomorphological setting. This study also shows stratigraphic correlation between existing wells and BP-1 well to establishes a standard stratigraphy of the Domi Basin.

  • The purposes of this study were to investigate the emotional consumption propensity and the preferences for sensibility factors of fabrics(color tone, pattern and texture image), and to analyse the differences according to demographic variables and relationships between emotional consumption propensity and preferences for sensibility factors of fabrics, focusing on male and female consumers in 20's, 30's and 40's. The emotional consumption propensity were classified into symbolic consumption propensity, individual consumption propensity, aesthetic consumption propensity and hedonic consumption propensity. The subjects attached great importance in the order of aesthetic consumption propensity, individual consumption propensity and symbolic consumption propensity. Those factors of emotional consumption propensity showed partially significant difference according to demographic variables. Female consumers preferred various color tones than men did, and preference for light color tone showed significant differences according to gender and occupation of consumers. The preferences for floral pattern showed significant difference according to gender, age, education, occupation and marital status of consumers. The factors of the texture images for the fabrics showed partially significant difference according to demographic variables except education of consumers. There were almost significant relationships between emotional consumption propensity and the preferences for sensibility factors for fabrics.

  • The description of vegetation cover and floral composition was undertaken in terms of phytosociological study in Dodamsambong(scenic site no. 44) and Danyangseokmoon(no. 45). In this study a total of 17 $relev{\acute{e}}s$ containing 144 taxa were collected and analyzed. Eight plant communities are differentiated, grouped into 4 physiognomic types: forest type(Buxus microphylla var. koreana-Thuja orientalis community, Tilia mandshurica-Quercus variabilis community, and Cynanchum wilfordii-Pinus densiflora community), mantle type(Cardamine leucantha-Neillia uekii community), secondary meadow type(Galium kinuta-Spodiopogon sibiricus community, Diarthron linifolium-Zoysia japonica community), and crevice type(Patrinia rupestris-Selaginella stauntoniana community, Hypodematium glandulosopilosum community). The vegetation of Dodamsambong and Danyangseokmoon is characterized by local flora, such as calciphilous plants, geological distribution-limit species, and endemic species. The soil depth, slope, and human impact have been identified as the most important differentiating ecological factors. Buxus microphylla var. koreana-Thuja orientalis community, Tilia mandshurica-Quercus variabilis community, and Patrinia rupestris-Selaginella stauntoniana community were evaluated highly by National Vegetation Naturalness. In order to restore the value of specific landscape for scenic site, we should improve the problems of protected area such as wrong management on habitat, forest fragmentation by facilities and decline in vegetation by lack of growing the next succession.

  • The purpose of this study is to investigate the changes and developments that occurred as a result of the exchanges of gyeong-geum(經錦), a warp-faced compound weave of East Asia, and wie-geum(緯錦), a weft-faced compound weave of West Asia. In order to maximize the efficiency of this research, topics were narrowed down to the weaving skills and patterns, and the period was limited to the Tang dynasty. The systematic characteristics and differences of gyeong-geum and wie-geum were compared and contrasted through different works of literature. Then the excavated remains of geum-textiles were analyzed and the characteristics of the geum-textiles were defined in chronological order. The origin of wie-geum is traced back to the time when West Asia started to imitate the weaving style of the East Asian gyeong-geum. When combined with the weaving skills of the West Asian, gyeong-geum, which broke through the West and developed into the weft-faced compound twill silk, or samite. The exchange of geum-textiles took place as the techniques of gastric filament woven geum-textiles returned to the East. Along with the pearl roundel motifs of Sassanian Persia, mythical animals and western motifs of hunter patterns were used for the patterns of wie-geumin during the early Tang dynasty. This tendency is related to pa-sa-geum(波斯錦), ho-geum(胡錦), beon-geum(番錦) according to the recorded literature. The 8th and 9th century are periods when the West Asian Persian style was abandoned and the East Asian style, samite, was established. Not only did S twist silk threads replace Z twists, but also the repetition of patterns unfolded along with the weft and the warp. As this tendency was strengthened after the 9th century, the expression of patterns became more vividly colorful and showed both elements of naturalism and realism. The characteristics of the Bosangwha(寶相花) pattern in the Tang period were established with the rampantly repeated rosettes with birds often holding auspicious branches, that fly amid floral compositions.

  • This study attempted to investigate the plastic characteristics of cyber punk fashion with a focus on fashion in the cyber punk movies in order to inquire into how the influence of the cyber punk taking the lead in the spiritual culture and way of life of the humankind in the 21th century would be expressed in fashion. For this purpose, it sought to analyze the beauty of new fashion creating the cyber environment and identify its contemporary meaning. An attempt was made to investigate the image of cyber punk fashion with a focus on fashion expressed in the cyber punk movies. As a result, the following findings were obtained: First, the image of cyber punk fashion expressed in the cyber punk movies was simplicity, which was to express the modest silhouette and details exclusive of decoration. In addition to clean and smooth gloss, it contained the modest image of resistance', not 'revolt' by borrowing the partial motive and image from existing punk fashion. The change of cyber punk fashion into the characteristic of concise, smooth external appearance brought about the restraint of its image and symbolism as well as its plastic characteristic. Second, it was characterized by the Eroticism nature of emphasizing the body line while expressing the future and modest image or exposing the body. Cyber punk fashion expressed the avant-garde image by using materials that gave a mysterious and future feelings, as well as unsymmetrical silhouette, the slit of body-conscious line, coarse cutting, the method of do-constructing and reconstructing the silhouette, the method of applying diverse underwears such as corset, brassiere and the like. Third, cyber punk fashion was marked by the nature of mined sex. It had the masculine image by using the black color containing the image of masculinity and resistance in female clothing and expressing the suit, coat and military looks giving an masculine impression. And it expressed the image of mixed sexes with the masculine image in male clothing by borrowing feminine images such as body-conscious line, widely cut neckline, floral decoration, leggings and the like. Fourth, cyber punk fashion was marked by naturalness. It was expressed as clothing made from silhouette, knit, cotton and the like in the atmosphere expressing love, comfortableness and truth. This contained the image of naturalness, a return to the primitive, that human being wanted to return to their original figure in the future element. The cyber punk movie may contain a dismal, gloomy future image on the whole, which can be overcome, and shows the possibility that it may grow into the alternative culture, not the revolting culture. The movie of 'The Fifth Element' demonstrates the meaning and role that shows the bright future image. It is thought that designers should make efforts for cyber punk fashion to perform its role in changing the gloomy future image into the bright image of society
