We usually try to accomodate ourselves to our nature surroundings interacting with nature. There fore I've decided to apply nature materials, esp. the pine to Hair Art as a way of expressing our feelings from Nature. 'Hair Art' is a follow-up study based on the various artistic point of view. There has been various works of 'Hair Art' with nature materials. However, it is rare to see a work of 'Hair Art' with the pine. That's why I've decided to study more about this. This study is a new experiment in 'Hair Art' against a conventional idea "Hair Art values practicability." Therefore, the primary goal of this study is to do much for the cause of learning in 'Hair Art' and encourages some development of 'Hair Art' industry. I've researched an image of a pine tree in art of Joseon Dynasty and contemporary art. Then I've tried to apply the image to a work of 'Hair Art'. First of all, in a view of expression technique for the symbolism of the pine, the artists in Joseon Dynasty drew pictures of a pine tree with a paintbrush but the modern artists make a new attempt from the thought of Modernism. We can find it in some photos. Next, to express traditional oriental idea such as 'unconventional and elegance', comtemporary artists chose the symbolism of the pine tree as an object of their works like pen and ink sketches from the thought of Modernism. Third, in a fusion style picture which contains features of both oriental paintings and western paintings and in a sexualism style picture that depicts a harmony of a male and a female as a shape of a pine, we can find colorful images of a pine tree and Their figurative beauty in art. Those are another symbols of the pine. In conclusion, the implication of the pine tree still hasn't changed even there are differences of drawings of pine tree in the past and the present. I've tried to combine these symbolic ideas of the pine with 'Hair Art' and made 5 hair styles. Throughout the process of researching this topic which is 'The Study of Hair Art Using The Symbolism of The Pine', I've realized that pine trees make it possible to express intrinsic tough spirit of human being and abundance in color and figurative beauty in art. I hope this can contribute to the field of 'Hair Art' and would become an important educational resource for further study.

Portions of chloroplast genes(psbD and rbcL) were amplified from Pinus thunbergii(Japanese black pine : black pine) and Pinus densiflora(Japanese red pine : red pine) by PCR and digested by a restriction enzyme, HaeIII, respectively. Two species specific cpDNA markers were identified. With the observed cpDNA markers, paternal inheritance of cpDNA in pine hybrids was verified in an artificial hybrid family between black pine(Chollanam 37) and red pine(Chungchongbuk 3). On the basis of paternal inheritance of chloroplast genome in a hybrid, 2 portions of cpDNA amplified from 115 individuals of Pinus densiflora for. erecta were screened to detect any traces of black pine specific cpDNA markers in P. densiflora for. erecta which has been postulated as an introgressive hybrid between red pine and black pine(Hyun el al., 1967). All the analyzed individuals of Pinus densiflora for. erects revealed the identical profiles of HaeIII digested psbD and rbcL genes to red pine. This result suggests that there is no introduced chloroplast genome of black pine in Pinus densiflora for. erecta and that there is no concrete evidence of treating P. densiflora for, erecta as an introgressive hybrid between red pine(♀) and black pine(♂).

Tricholoma matsutake (Pine mushroom) is expensive, and its artificial cultivation has been tried in several countries. Until date, the only successful cultivation of artificial pine mushroom in pine forests uses matsutake-infected pine trees. The National Institute of Forest Science in Korea has been restudying this method since 2000. Success in fruit production and reproduction was achieved in 2010 and 2017, respectively, in the same locale. The successes proved that pine mushrooms could be cultivated artificially in the field using matsutake-infected pine trees. The fruiting of pine mushroom in October 2010 occurred 6 years, 6 months after the transplantation of matsutake-infected pine trees. Five pine mushrooms reoccurred in September 2017, 13 years, 5 months and 15 years, 5 months after the transplantation of the respective matsutake-infected pine trees. The distance between the matsutake-infected pine tree and the pine mushrooms was 12 cm at 6.6 years, 90~115 cm at 13.5 years, and 95 cm at 15.5 years. Fruiting bodies occurred 13~16 days after the underground temperature declined to below $19^{\circ}C$. In conclusion, the use of matsutake-infected pine trees remains the only way to artificially cultivate pine mushrooms. More knowledge of the environmental factors affecting matsutake fruiting would be beneficial.

This study was carried out to evaluate litterfall dynamics in three adjacent coniferous tree plantations (larch: Larix leptolepis; red pine: Pinus densiflora; rigitaeda pine: P. rigitaeda) planted in the same year (1963), and growing under similar environmental conditions in the Sambong Exhibition Forests, Hamyang-gun, Gyeongsangnam-do. Litter was collected monthly between July 2006 and June 2008. Needle, broad leaf and total litter inputs followed a similar monthly pattern in the three coniferous plantations. The amounts of needles, flowers, and miscellaneous litter were significantly lower in the larch than in the two pine plantations, while branch litter was significantly higher in the larch than in the two pine plantations. Average total litterfall for two years was significantly higher for the pine (5,475 kg $ha^{-1}\;yr^{-1}$ for red pine and 5,290 kg $ha^{-1}\;yr^{-1}$ for rigitaeda pine) plantations than for the larch (3,953 kg $ha^{-1}\;yr^{-1}$ plantation. Needle litter comprised about 73.1% of total litterfall for the rigitaeda pine, 70.8% for the red pine and 62.9% for the larch plantations. Our results demonstrate that litterfall inputs can be affected by tree species.

This study was carried out to investigate the effect of Pine needle extract on lipid oxidation and free radical reaction in iron sources reacted with active oxygen species. The results were summarized as follow; The pine needle extracts didn`t show a distinct effect on reduction of lipid oxidation if the iron ion didn`t exist in oil emulsion. The pine needle extracts played role as a strong chelating agents to bind iron ion if Ferrous iron(Fe\ulcorner) exist in oil emulsion. Ferric iron(Fe) was lower effect than Ferrous iron(Fe) on free radical reaction in oil emulsion. And also, the Fe\ulcorner reacted with pine needle extract did not show distinct effect on free radical reaction, compared to Fe\ulcorner reacted with pine needle extract. And also, Pine needle extracts reacted with H\ulcornerO\ulcorner were tended to show a low oxygen scavenging ability in case of H\ulcornerO\ulcorner only was existed, compared to those of H\ulcornerO\ulcorner + Fe\ulcorner complex. Pine needle extracts were the most powerful Fe\ulcorner binding agents, compared to other strong synthetic antioxidants such as EDTA and DTPA.

Results for the concentrations of total polychlorinated biphenyls (total PCBs) and the PCB profile with different types of leaves from four coniferous trees (pine needles) at the same sampling site are presented. Concentrations of total PCBs detected in pine needles were very similar among them regardless of their different types of leaves, which means a possibility for bio-monitoring regional contamination of PCBs. Correlation coefficients(r) of PCB congeners between pine needles were very significant (r>0.97, p<0.001), which showed that PCB congener's patterns of each pine needle were similar. Profiles of PCBs detected in pine needles showed correlation with gaseous phase PCBs in air, otherwise not with particle phase PCBs in air. Therefore, it was estimated that dry gaseous deposition was a principal pathway of PCBs accumulation in pine needles. In addition, although we analyse a different types of leaves in pine needles at the same region, they can be used to identify regional contamination patterns of PCBs for larger regions.

The purpose of this study was to investigate usefulness of the pine needles extract on Atopic Dermatitis(AD)-like skin lesions. To investigate the effect of pine needles extract in vivo, atopic dermatitis (NC/Nga) mice using DNCB (2.4-Dinitrochlorbenzene) was used. NC/Nga mice were challenged with DNCB during 2 weeks to develope AD-like skin lesion. After that, pine needles extract was applied to AD-like skin lesion on the backs of the NC/Nga mice during 3 weeks. The efficacy of pine needles extract in the NC/Nga mice was evaluated by measurement of the skin lesion severity(NC mouse score), the serum IgE level, epidermal thickness changes, and mast cell number. Blood was collected from the retro-orbital area and the level of IgE in the blood was measured. The epidermal thickness and mast cell number were observed by microscopic method after H&E stain. The serum IgE levels were decreased after treatment with pine needles extract. The epidermal thickness and mast cell number were decreased after treatment with pine needles extract. To conclude, the topical application of pine needles extract suppressed the progression of AD-like skin lesion.

Peroxidase activities and isozyme patte군 of the pine needles (Pinus densiflora) were examined and compared in the coastal regions of Anmyum-Do(Choongnam, Taean-Gun) and inland regions of Shinchang-Myun(Choongnam, Asan-City). The pine needle peroxidase from Anmyum-Do showed approximately three times higher specfic activity than Shinchang pine needle peroxidase. The pine needle extracts of Anmyun-Do and Shinchang contained three anionic isoperoxidases, named A1, A2 and A3, when subjected to starch gel electrophoresis at pH 7.0. Cjationic isoperoxidases could not be found in both extracts., However, there existed unique isoperoxidase An only from the extracts of Anmyun-Do pine needles under the salinary environment. Moreover, the specific activities of catalase and glucose-6-phosphate dehydrogenase from Anmyun-Do, known for the inducible enzymes under the stress condition, were about 1.8 times higher than those of Shinchang pine needles. However, the specific activities of other enzymes did not show great differences between the two regions. Considering the above results of the higher specific activity of peroxidase and the unique expression of isoperoxidase An, pine needle peroxidase might involve in the defence mechanism against the salinary stress of Anmyun-Do.

We extracted pine-needles using ethanol as solvent, and we obtained the refined oil component from pine-needles extract. Also we tested the tyrosinase activated inhibition effect with melanin experiment and analysed with ICP/OES and UV/VIS. Accordingly we obtained the next conclusion from the result of this experiment. From the first result of this experiment, we could know that the degree of recovery of refined oil component from pine-needles extract appeared in about 8.0%. From the second result of this experiment, we could know that the tyrosinase activated inhibition rate increased more and more in case of increasing concentration of pine-needles, green-tea, vitamine-C. Also we could know that vitarnine-C influences to tyrosinase activated inhibition contained in pine-needles. From the third result of this experiment, we could know that inorganic materials of Ca, Mg, V, Mn, etc contained in pine-needles detected with ICP/OES analysis, and the absorbance of pine-needles extract appeared very high in UV/VIS analysis.

The distribution and form of pine wood nematode (PWN) were investigated in Jinju-si and Sacheon-si areas, where infested with pine wilt disease (PWD). The average PWN population per g of the tubulation part in the wilted Japanese balck pine were 381.2 and 341 in Jinju-si and Sacheon-si, respectively. The PWN population per g of affected Japanese black pine with wilt rate below 60% were 556 and 518 in Jinju-si and Sacheon-si, respectively. The ratios of PWN and other plant-parasitic nematode in the wilted Japanse black pines were 48% vs. 52% in Jinju-si and 53% vs. 47% in Sacheon-si after exposure to PWD for 1 year. The survivorship of pine wood nematode in the sampled trees after 1 year was 0-10% in the Jinju-si area and 5-20% detected in the Sacheon-si area. In the forest areas affected by PWN, the highest survival rates were 37.2% and 39.8% at 25 cm diameter at breast height (DBH) in Jinju-si and Sacehon-si, respectively, while the highest wilt rates were 30.5% and 28.3% at 30 cm DBH in Jinju-si and Sacehon-si, respectively.
