  • This research is to develop kiln-drying schedules for 2.7 mm thick boards of Neolitsea sericea and Dendropanax morbifera, which grow in the southern region of Korean Peninsula. These two species are lesser-known to woodcraft industry in this country. The proper USDA drying schedules for Neolitsea sericea and Dendropanax morbifera were found to be T10-C6 and T10-E6, respectively, by using the Quick Oven-drying Method. The boards dried in a kiln with the newly-developed schedules were revealed to be free from warping and checking.

  • The complete chloroplast (cp) genome sequence of Neolitsea sericea was determined by Illumina sequencing. The complete cp genome was 152,446bp in length, containing a large single-copy region of 93,796 bp and a small single-copy region of 18,506bp, which were separated by a pair of 20,072bp inverted repeats. A total of 112 unique genes were annotated, including 78 protein-coding genes (PCGs), 30 transfer RNAs, and four ribosomal RNAs. Among the PCGs, 18 genes contained one or two introns. A very low level of sequence variation between two cp genomes of N. sericea was found with seven insertions or deletions and only one single nucleotide polymorphism. An analysis using the maximum likelihood method showed that N. sericea was closely related to Actinodaphne trichocarpa.

  • Two compounds were isolated from the diethylether and ethyl acetate fraction of hot water extracts by TLC and column chromatography as dyeing components. The isolated compounds were characterized as H-dibenzoquinoline-2,10-diol,5,6,6a,7-tetrahydro-1,9-dimethoxy-6-methyl (compoundI) and lyoniresinol (compoundII) by NMR and Mass spectrophotometry. To investigate if the isolated compounds are involved in the dyeing process, HPLC analysis was used. The retention time of the components from dye used in the study and the dye decolorized from the dyed substrate, silk by ethyl acetate were compared to conform the identity of those compounds. The retention time of the components from the dye and decolorized solution were identical. As a results, those two compounds were considered as dye bound to the silk.

  • To investigate the dying properties of the extracts from different parts of Neolitsea sericea Koidz on Hanji, the dye materials were prepared from the extraction methods using $1{\ell}$ of hot water and alkaline solution with 40 g of leaves, bark, and wood each. K/S values and H (V/C) values of the Hanji dyed at different pH, temperature, time, and concentration of extract were determined using a spectrophotometer, and the maximum absorption wavelength of the dyed Hanji was 400 nm. From the analyzed data, the optimum dying conditions were pH 5 of dying solution, $70^{\circ}C$ of dying temperature, 40 minutes of dying time, and 100% of dye concentration. The color of dyed Hanji was Y to YR and color R- and RP-type could also be formed from the different treatment conditions. From the dyeing using mordants, amount of the bound dye materials was high in the pre-mordanted Hanji and in Hanji treated with extracts from the leaves. Also, the amount of the bound dye materials in the pre-mordanted Hanji was higher when aluminum and iron mordant was used rather than other mordants. Not likely with this, amount of the bound dye materials in the post-mordanted Hanji was higher when copper mordant was used. In color, Hanji treated extracts from the leaves appeared as Y-type and ones treated with extracts from bark and wood showed YR-type.

  • Vascular plants of Island Gageo in Jellonamdo were investigated 10 times from August, 2005 to August, 2011. In the result of survey, the flora of this island consists of 341 taxa totally; 93 families, 246 genera, 289 species, 7 subspecies, 36 varieties and 9 forms. Yellow-fruit bearing plants of $Neolitsea$ $sericea$ which were found in this island are newly named as $Neolitsea$ $sericea$ (Bl.) Koidz. for. $koreana$ M. Kim. There were 8 Korean endemic plants such as $Hosta$ $yingeri$, $Impatiens$ $furcillata$, $Saussurea$ $pseudo-gracilis$, etc. Also 3 Korean endangered species which is designating by Ministry of Environment such as $Osmanthus$ $insularis$ and $Cyrtosia$ $septentrionalis$ and 9 rare and remarkable species such as $Viburnum$ $japonicum$, $Asplenium$ $yoshinagae$, $Broussonetia$ $kazinoki$ for. $koreana$, etc. were found in this island. Furthermore, 11 taxa of naturalized plants (3.2%) were also observed in this island.

  • The research was carried out in order to find climate factors which determine the distribution of Neolitsea sericea, and the potential habitats (PHs) under the current climate and three climate change scenario by using species distribution models (SDMs). Four climate factors; the minimum temperature of the coldest month (TMC), the warmth index (WI), summer precipitation (PRS), and winter precipition (PRW) : were used as independent variables for the model. Three general circulation models under A1B emission scenarios were used as future climate scenarios for the 2050s (2040~2069) and 2080s (2070~2099). Highly accurate SDMs were obtained for N. sericea. The model of distribution for N. sericea constructed by SDMs showed that minimum temperature of the coldest month (TMC) is a major climate factor in determining the distribution of N. sericea. The area above the $-4.4^{\circ}C$ of TMC revealed high occurrence probability of the N. sericea. Future PHs for N. sericea were projected to increase respectively by 4 times, 6.4 times of current PHs under 2050s and 2080s. It is expected that the potential of N. sericea habitats is expanded gradually. N. sericea is applicable as indicator species for monitoring in the Korean Peninsula. N. sericea is necessary to be monitored of potential habitats.

  • The purpose of this study was to suggest vegetation management Planning and plant community structure of Camellia Japonica forest at Hakdong, Kojedo, Hallyo-Haesang National Park. Forty-six plots(l00$\m^2$/plot) were established in Camellia japonica forest and surveyed. By DCA ordination technique and mean importance value analysis, the plant communities were classified into four community types, which were Camellia japonica community, Camellia japonica-Eurya japonica community, Camellia japonica-Neolitsea sericea community, Chumaecyparis obtusa-Camellia japonica community. It was supposed that Camellia japonica-Neolitsea sericeu community succeeded to Neolitsea sericea community. The others would not be replaced by another woody species. The vegetation management for successional controls in long-term basis were suggested; for the short-term basis, the species of Chamaecyparis obtusa, Neolitsea sericea and Eurya japonica should be removed. The species of Quercus serrata, Prunus sargentii, Meliosma myriantha, Machilus thunbergii and Litsea japonica. must be controlled under the long-term management of vegetation.

  • The distribution of three typical warm-temperate evergreen trees, Quercus acuta Thunb., Neolitsea sericea (Blume) Koidz., and Machilus thunbergii Siebold & Zucc., were surveyed on the Korean Peninsula based on field and specimen investigations and the distribution maps of the three species were prepared. The distribution patterns of the species correspond to the south coast floristic region in Korea, which includes the distributional areas of Jeju-do, Isl. Ulleung, the southern coastal areas, and the areas up to the islands around Incheon in the Yellow Sea. The northernmost limit of the distribution of Quercus acuta is Isl. Nap of Incheon in the west, and a new distribution was found at Isl. Ulleung in the East Sea; additionally, the limit of Neolitsea sericea is the Deojoek archipelago of Incheon. The northernmost limit of Machilus thunbergii is Isl. Daecheong of Incheon, which is the highest latitude among those of the three species. This distribution survey of evergreen broad-leaved trees in Korea can be used as basic data for the delimitation of floristic regions and as a bio-indicator of climatic change.

  • To study plant community structure and successional sere of the Kojedo District, Hallyo-Haesang National Park, fifty six plots were set up and surveyed(each plot $l00\m^2$). Fifty-six plots were classified into four community, Quercus variabilis-Zelkova serrata community(I), Q. variabilis-Cinnamomum japonicum-Neolitsea sericea community(II), Pinus thunbergii-C. japonicum-N. sericea community(III), P. thunbergii-P. densiflora community(IV) by TWINSPAN technique. Most area of forests in Kojedo district are artificial or coppice forest after artificial disturbance. The age of four community were about 35~40 years and the number of species 32~44 species per $600\m^2$. Ecological succession had been proceeded from deciduous broad-leaved species(Q. variabilis-Z. serrata etc.), P. thunbergii, P. densiflora to evergreen broad leaved forest(C. japonicum, N. sericea etc.).
