  • This study was carried out to analyze annual diameter growth characteristics for major 11 tree species using the data for Gangwon province of the National Forest Resources Inventory in 2007. The annual diameter growth of coniferous species was 5.02 mm, 4.70 mm, and 3.90 mm in Korean white pine, Japanese larch, and Korean red pine, respectively. In growths of the deciduous trees, dogwood, basswood, and cork oak had 3.55 mm, 3.48 mm and 3.01 mm, respectively. Average of the annual diameter growths for all species was 3.38 mm. The relationship between diameter growth and age class showed that the growth rate decreased for all species as age increased. The age class II had the highest annual diameter rate. In relation of the stand density(trees per hectare) and diameter growth, the diameter growth tended to decrease as the stand density increased for most species, especially Korean white pine, cork oak, and basswood. Finally age had the highest value in the correlation coefficients between measurement factor and growth rate regardless of species.

  • The root-bark of the mulberry tree has been used as a medicine with antitussive, antiphlogistic, diuretic etc. in Korea. Among many kinds of mulberry trees, Morus Lhou has been widely cultivated in our country. In this experiment, three substances were obtained from the root-bark of Morus Lhou removed its cork layer by column chromatography of methanol extract. One of the substances was supposed as ${\alpha}$-amyrin acetate, another was alyceride, the other was confirmed as ${\beta}$-sistosterol by chemical and physical methods.

  • 박물관에서 소장품의 저산소 농도 살충처리를 위해, 직물, 염색 직물, 종이, 염색지 및 채색편의 색상 및 기계적 성질에 미치는 영향을 평가하였다. 저산소 농도 살충 조건은 질소 및 아르곤을 사용하여 조성한 산소 농도 0.01%, 온도($20^{\circ}C$, $25^{\circ}C$, $30^{\circ}C$), 습도 50%, 살충 시간 30일이였다. 직물은 생견 직물, 자외선 열화 생견 직물, 정련 견직물, 자외선 열화 정련 견직물, 광목 및 자외선 열화 광목을 평가 대상으로 하였다. 천연염색 견직물과 면직물은 생쪽, 쪽, 홍화, 자초, 꼭두서니, 소목, 황벽, 울금, 치자, 황련, 괴화, 코치닐, 자광, 오리나무, 오배자, 밤피 및 쪽과 홍화 복염, 쪽과 황벽 복염, 쪽과 괴화 복염, 쪽과 소목 복염 등 천연염색 직물 각 20종이었다. 평가 대상 종이는 한지(닥지, 닥과 볏짚 혼합지), 화지(안피지), 면지, 린넨지, 면, 아마 및 마닐라삼 혼합지, 복사지, 신문지, 반수 닥지 등 9종이었다. 염색지는 한지에 쪽, 소목, 꼭두서니, 홍화, 치자, 황벽, 괴화로 천연염색한 것을 평가하였다. 채색편은 반수 한지와 반수 화견에 석청, 석록, 주사, 주, 석자황, 등황, 연단, 대자, 석간주, 니람, 연지(자광, 코치닐, 홍화, 꼭두서니), 뇌록, 스몰트, 울트라마린블루, 라피스라즈리, 프러시안블루, 백토, 연백, 호분(굴껍질 호분, 대합껍질 호분) 등 23종의 안료 분말을 아교물에 개어 도포한 것이었다. 평가 대상 재료에 대해 저산소 농도 살충처리 전후의 색차를 평가한 결과, 색차 ${\Delta}E^*$는 1.5 이하이거나 대조군보다 낮았으며, 직물 및 염색 직물의 살충처리 전후의 인장강도 변동률은 기준치 이하였다. 그리고 가스(질소와 아르곤)와 살충 온도에 따른 색차 및 인장강도 변동률에 대한 영향도 없었다.

  • Yellow dye-stuffs in natural plant were extracted from a gardenia, saffron, safflower, amur tree and pagoda. And then they were used to color Korean handmade paper(Hanji) on using a mordant. The results of the degree of discoloration are as follows. 1. As for a gardenia(Gardenia jasminodes Ellis for. grandiflora Makino), the effects of coloring were outstanding in the acid area. But for the preservation, it might be desirable that used a lye in a dye-stuff obtained at $40{\pm}5^{\circ}C$. 2. As for saffron(Curcuma longa L.), when used alum as a mordant, it was colored to a medium yellow color with green color. But easily discolorated and was not desirable. And, it didn't fit in a dye-stuff of Hanji. 3. For safflower(Carthamus tinctorius L.), when pH was in the low acid it was colored to the cleaner yellow color. It was the distinction of discoloration that the degree of brightness's increase was low. 4. For amur cork-tree(Phellodendron amurense Rupr.), the effects of yellow coloring were great in the areas of acidity and alkali. But, when used alum, the degree of the discoloration was high and was not effective. 5. For pagoda tree(Styphnolobium Japonica L.), using a calcium hydroxide as a mordant, enabled the more than average yellow to be gained. The degree of discoloration was good.

  • In our country there are five species of Morus genus including Morus alba L.. Also their varieties and hybrids are distributed so much. In sucession of previous report we collected control and marketing specimens of Mori Cortex Radicis, comparative experiments were pharmacognostically carried out to identify the control specimen by the differences of external and internal morphology. It was difficult to identify marketing specimens by external morphology, because they are similar in spite of conparating with control specimen which the origin is definite. In internal morphology, medullary ray is developed near the cambium to primary bark in control specimen A(Morus alba series) and C(M. Lhou series), but less developed in B(M. bombycis series). The difference of these three series was observed. The thickness of cork layer is almost the same($7{\sim}12$ layers) in A and C series, but B is thin layer and sample E(that on the market) is generally more thick and has a stick cork cell. The kinds of starch, Ca-oxalate and latex, cell centents were same, but it was easy to identify them by the differences of their distribution. The bast fibre of D(wild specimen) and E were light lignified, latex tube of A and C series was richer distributed than others. These results show that the origin of Mori Cortex Radicis on the market can be appreciated in four groups of Korean Morus genus which are M. alba, M. bambycis, M. Lhou series and the others.

  • The dyeing behaviors of berberine chloride, palmatine chloride hydrate, and Phellodendron bark extract on silk fabric were investigated to evaluate palmatine as another chromophoric substance of Phellodendron bark. The dyeing conditions were composed of combinations of pH (3, 5, 7, 9), temperature (10, 30, 55, $80^{\circ}C$), and time (10, 30, 60 min). The results indicate that palmatine was comparable to berberine in the dyeing behaviors tested for this study and the results were statistically significant. The dye exhaustion and dye uptake of palmatine-CH were slightly lower than berberine-C, which however were not statistically significant. Similar to berberine-C, palmatine-CH favored a pH 7 condition for both dye exhaustion and dye uptake. However, palmatine-CH favors a higher dyeing temperature and longer dyeing time than berberine-C for superior dyeing results.

  • In order to improve the light fastness of a natural colorant berberine, several natural antioxidants such as gallic acid, L-ascorbic acid, and ${\alpha}-tocopherol$ were applied by aftertreatment method. Even though the increase in light fastness of berberine colorant was not substantial, L-ascorbic acid was the most effective. It was considered that this improvement of the light fastness was due to high antioxidation action of L-ascorbic acid to colorant, which led very highly excited species of the colorant formed by photo-energy to return to the original stable state without being decomposed.

  • As the substitute of synthetic coloring materials for hair dyeing, we selected some natural ones of three primary colors such as sappan wood, logwood(red), gardenia blue(blue) and amur cork tree(yellow). Mixed colorants and metallic mordanting technique were used to widen the color space of dyed samples. In view of similarity in morphological and chemical structure, wool was adopted as the reference material for human hair to evaluate the color properties of hair dyeing. The color properties of the dyed samples were evaluated by using CIE $L^*a^*b^*$ and Munsell color systems. The addition of an alum or ferrous mordants was effective to expand the color space of hair and to increase the colorfastness to washing and light more than the rating of 1. Displaying the dyed samples by using Munsell color system, better linearity of hue values between the dyed samples of wool and human hair was shown when alum mordant was used.

  • In order to analysis on color difference of natural dyes, I have dyed Hanji, cotton, silk fabric and exposed them to carbon arc light. The results of experiment have been analysed by wavelength of maximum absorption, amounts of dye uptake, color difference, Hunter's value and Munsell's value. Gardenia Jasminoides is monogenetic dye, but it gained darker color by pre-mordanting method used Al mordant agent and greenish yellow color by Fe mordant agent. whereas Curcuma, an Amur cork, and bud of pagoda tree are shown as greenish yellow color, and A barberry root, Betel nut, and Rhubarb are shown as reddish yellow color. these gained khaki colored dyed fabric by Fe mordanting. In addition, Sappan wood showed great result in pre-mordanting. Especially, it gained dark red color by Al pre-mordanting. The pink color was shown by post-mordanting. and Logwood showed great dyeing result in Hanji and cotton better than silk. Specially pre-mordanting was effective. Hanji and cotton showed greenish blue color by Al pre-mordanting, and silk showed brown color.
