  • Phytosociological study was carried out to investigate the structural characteristics of Humulus japonicus community in the Middle area of Korea. The vegetation data of total 67 $relev\acute{e}s$ were analyzed by the $Z\ddot{u}rich$-Montpellier school's method. Upper layer plant communities of Humulus japonicus were classified into four community groups : Humulus japonicus-Artemisia princeps community, Chenopodium album community, Setaria viridis-Echinochloa crus-galli community and Typical community. Lower layer plant communities were classified into five community groups : Galium spurium-Stellaria aquatica community, Equisetum arvense community, Persicaria theunbergii community, Echinochloa crus-galli-Digitaria ciliaris community and Typical community. According to the results of canonical correspondence analysis by vegetation and environmental factor, Setaria viridis-Echinochloa crus-galli community of upper layer was distributed throughout the soil with high relative light and soil hardness. Chenopodium album community appeared in the soil with high pH. Galium spurium-Stellaria aquatica community of lower layer was formed in the high soil pH. Persicaria theunbergii community and Echinochloa crus-galli-Digitaria ciliaris community were distributed in the soil with high moisture.

  • A phytosociological study of forest vegetation of Mt. Kaya was carried out from August 1988 to September 1992. The forest vegetation of the area was classified into 3 communities (Quercus monogolica community, Lindera erythrocarpa community, Pinus densiflora community) and 3 subunits (Rhododendron mucronulatum subunit, Platycarya strobilacea subunit, typical subunit of Pinusdensiflora community). The Pinus densiflora community was located at the lower altitudes (100~300m) than those of other communities. The Lindera erythrocarpa community was located at the upper altitude (500m). Most of the inverstigated area were occupied by the secondary forest of Pinus densiflora community in the actual vegetation map and the profile diagram, suggesting that it was frequently destroyed by human interference

  • To investigate the plant community structure of Paekdam-Valley in Soraksan National Park, fifty-two plots have been set up and surveyed. By DCA ordination technique, the plant communities were classified into fkve community types, which were Pinus densiflora community and Q. mongolica community. It was supposed that Q. serrata community change to C. laxiflora community. It seemed that P. densiflora community, deciduous broad-leaved mixed forest and Q. serrata community would not be replace by another woody species. And it seemed that C. laxiflora community succeeded to Q. serrata community, so it was similar to the typical ecological succession of natural forest in the middle temperate regions. The range of Shannon's diversity index was 0.9827~1.2946(Unit area : 400m$^2$) and that was over another Korean National Parks area relatively.

  • An underwear originated from when a human lost his purity and recognized his situation. But, it could not be sure when underwear and an outer garment were classified according to a function. An underwear has been used for a decorative and mental function, as well as a practical one. Also, it is the most fundamental medium to understand a human and a period. However, many studies on outer garments not an underwear have been done till now Therefore, this study was done to be arranged and analyzed materials scattered in order to give a correct understanding of an underwear as a clothes. The data were based on the existing fashion pamphlets, fashion magazines and other materials. The main results were as follows; Female's contemporary underwear was classified into Hosiery, Foundation and Lingerie. The Hosiery was again classified into chemise, combination, drawers and brief. The most typical hosiery was a chemise for a health and hygiene, and the drawers was adhered closely to a body. The Foundation which had a function to be well shaped was classified into Brassiere, Girdle, All in one, Body suit, Corset, Waist nipper and Garter belt. A typical contemporary foundation was a brassiere and a girdle. A brassiere had a role to support the breast up and A girdle compensate a hip area. The Lingerie which made body silhouette be vivid was classified into Slip, Panty, Wintum, Linge, Home lingerie, and so on. A slip, a panty and a lingo were typical lingeries. A slip made an outer garment be well-formed.

  • The purpose of this study was to analyze forest vegetation type classification and relationships between the type and environment factor in Mt. Dutasan. Data were collected by total of forty six plots using Z-M phytosociological method from June to October, 2016, and analyzed by vegetation classification, canopy layer structure and relationships between vegetation unit and environment factor using coincidence methods. As a result of vegetation type classification, Quercus mongolica community group was classified at a top level of vegetation hierarchy that was classified into Rhododendron schlippenbachii community and Betula costata community. R. schlippenbachii community was divided into Lychnis cognata group and R. schlippenbachii typical group. L. cognata group was subdivided into Veratrum oxysepalum subgroup and L. cognata typical subgroup. B. costata community was divided into Fraxinus mandshurica group and Betula schmidtii group. F. mandshurica group was subdivided into Weigela subsessilis subgroup and Cimicifuga heracleifolia subgroup. Therefore the forest vegetation was composed of six vegetation units with two kinds of bisected species groups and fourteen species groups. As the result of an analysis of canopy layer structure, there were two kinds of structures with monotonous structures V. oxysepalum subgroup (vegetation units 1), L. cognata typical subgroup (vegetation units 2), W. subsessilis subgroup (vegetation units 4) and complicated structures R. schlippenbachii typical group (vegetation units 3), C. heracleifolia subgroup (vegetation units 5), Betula schmidtii group (vegetation units 6). The vertical layer structure of vegetation unit 5 was the most developed and vegetation unit 6 had the lowest coverage of herb layer. According to the correlation between vegetation unit and environmental factor, R. schlippenbachii community (vegetation units 1~3) and B. costata community (vegetation units 4~6) were classified based on 1,100 m of altitude, middle slope, twenty of slope degree, twenty percents of bare rock and thirty centimeters of DBH in tree layer. R. schlippenbachii community (vegetation units 1~3) showed positive correlation with altitude, topography and B. costata community (vegetation units 4~6) showed negative correlation tendency with them.

  • The forest vegetation occurring mainly at the mountain areas in periphery of Seoul were inversigated phyeosociologically. The granitic rocky outcrops are typical physiognomy on the study areas. The greater part of forests was the secondary vegetation to be disturbed by hyman impacts, because of being situated near the metropolis with a highly dense population. Four community types were largely differentiated by species composition. The representitive ones were the Quercus monogolica community and Pinus densiflora-Juniperus schinensis community, which are predominantly gorwing at the slopes above about 100m in altituse and the rocky ridges, respectively. The Betula chinensis-Potentilla dickinsii community at several single-peaks of windswept and the Zelkova serrata-Prunus padus community at stony valley are sporadically growing in a small area.
