The purpose of this study were to analyze the species and tree-ring dates of coffin woods excavated at Yerim site in Yesan, Chungnam, Korea. We sampled 12 pieces of woods from two coffins. The species of all coffin woods were identified as red pine group, most likely, $Pinus$ $densiflora$. The last rings of both coffins were dated A.D. 1557 and A.D. 1601, respectively. The tree-ring dates indicated that the coffins were made in the late 16th and early 17th century.

Environmental specimen bank (ESB) is a new tool to assess ecosystem in environmental impact assessment (EIA). ESB looks at changes in the concentration of pollutants in human and environmental specimens over long periods of time through retrospective analysis of archived samples. Korea started to design its National Environmental Specimen Bank (NESB) in 2007 and planned to launch an operational pilot project by 2010. NESB prepares five Standard Operating Procedures (SOPs) of shoots of Red and Korean pine, leaves of Mongolian oak, Pigeon's egg, and Common carp's muscle out of 14 planned specimens in 2009. ESB contributes to monitoring the effectiveness of EIA projects and policies by providing a time capsule through ecosystem assessment of representative species. This study reviews ecosystem assessment in EIA and the ESB establishment in Korea and probes NESB applications in ecosystem assessment.

Wood cell-wall modification with acetic anhydride, lumen filled with styren monomer and methyl methacrylate, and a combination of these two treatments were studied for their effectiveness for dimensional stability. Compared to those of untreated Pinus densiflora Sieb. et Zucc and sole acetylated red pine, The combination of acetylation and impregnation with methy methacrylate greatly reduced water absorption, increased ASE to the best and gave better bending strength and compression strength.

The endophytic fungi were isolated from red pine trees (Pinus densiflora) that were distributed in three sites of Chungbuk, Korea. Twenty fungal isolates were isolated from 16 trees and divided into 8 groups by morphological characters. The fungal isolates were identified using the sequences of ITS region of rDNA; Lophodermium complex, Sydowia polyspora, Hymenula sp., Sistotrema brinkmannii, Septoria pini-thunbergii, Earliella sp. Lophodermium spp. were the most frequently found fungal species the across sites and firstly detected from Pinus species in Korea by molecular work.

This study aimed to investigate differences in ectomycorrhizal (ECM) fungal communities between disturbed sites and undisturbed old forest sites. ECM root tips of Pinus densiflora were collected from 4 sites disturbed by human activities and 3 undisturbed old forest sites adjacent to the disturbed sites. Results in this study showed that the number of ECM root tips, species diversity, and number of species were significantly higher in the disturbed sites than in the undisturbed sites, suggesting that the ECM fungal community structure was affected by the degree of disturbance.

This study aims to date wooden coffins excavated from graves in Shinnae-dong, Seoul, South Korea, using dendrochronology. The species of woods used to make the coffins were identified as Pinus densiflora S. et Z., one of the major conifers in Korea. Of 12 graves, 10 were successfully dated using various red-pine chronologies of South Korea. Due to the absence of the last-formed tree ring before felling, the number of sapwood rings, used to obtain likely cutting dates, had to be estimated. The terminus post quem for two coffins without plaster frames were AD 1548 and AD 1571, respectively. Eight coffins with plaster frames yielded estimated dates from AD 1664 to AD 1799. The tree-ring dates indicated that the coffins with plaster frames in Shinnae-dong were constructed approximately 100 years later than those without plaster frames.

주거 건축 및 가구산업의 자재로써 합성목재(Wood-Plastic Composites)는 점차 각광받고 있다. 본 연구에서는 합성목재의 연소특성을 살펴보기 위하여 한계산소지수 측정(ASTM D2863) 및 콘칼로리미터 시험(ISO 5660-1)을 실시하였으며 또한 일반목재인 적송(red pine)과 방부 처리를 한 방부목에 대하여도 동일한 시험을 통하여 합성목재와 연소특성을 비교 검토하였다. 한계산소지수 측정결과 합성목재가 적송 및 방부목에 비해 가장 낮게 측정되었다. 콘칼로리미터 시험결과 합성목재의 열방출률값이 가장 빨리 피크치에 도달하였고 점차적으로 감소하였다. 합성목재의 최대 열방출률 값 및 평균 열방출률 값은 적송 및 방부목에 비해 가장 높게 나타났으며 총 방출열량 또한 가장 높게 나타났다.

The usefulness of the multi-temporal satellite image to monitoring the vegetation recovery process after forest fire was tested. Using multi-temporal Landsat TM and ETM＋data, NDVI and NBR changes over times were analyzed. Both NDVI and NBR values were rapidly decreased after the fire and gradually increased for all forest type and damage class. However, NBR curve showed much clearer tendency of vegetation recovery than NDVI. Both indices yielded the lowest values in severely damaged red pine forest. The results show the vegetation recovery process after forest fire can detect and monitor using multi-temporal Landsat image. NBR was proved to be useful to examine the recovering and development process of the vegetation after fire. In the not damaged forest, however the NDVI shows more potential capability to discriminate the forest types than NBR..

소나무 채종원내 클론 간 교배양식을 구명하기 위해서 4개의 nSSR 표지와 6개의 cpSSR 표지를 이용하여 소나무 채종원 내에서의 타가교배율, 기여 화분친 수, 화분오염율을 산출하였다. cpSSR haplotype에 근거한 타가교배율은 94~100%로, 평균 98.9%의 타가교배율이 산출되었다. nSSR genotype에 근거한 타가교배율은 90.3~100%로, 평균 95.9%의 타가교배율이 산출되었다. 별개의 DNA 표지분석에서 자가교배로 확인 되었던 종자들을 두 표지를 동시에 비교하여 확인한 결과 타가교배 종자로 최종 확인되었다(누적 타가교배율 100%). 화분오염율은 최소 43.6%(강원10)에서 최대 56.4%(강원12)로 평균 48.9%로 계산되었다. 종자의 cpSSR haplotype을 근거로 확인한 기여 화분친은 경북38에서 21개로 최대치가 확인되었으며, 강원10에서 13개로 최소치가 확인되어 평균 16.2개의 기여 화분친이 확인되었다. 결론적으로, 안면도 소나무 채종원 ’77단지내 클론간 높은 타가교배율이 확인됨으로써 채종원산 종자의 유전적 안정성을 기대할 수 있으며, 안면도 소나무 채종원 '77단지 내 교배양식 분석을 통해서 확인된 결과가 향후 전진세대 채종원 조성 및 관리에 유용한 정보를 제공할 것으로 기대된다.

The ten traditional symbols of longevity are represented as 10 which means perfection in oriental philosophy, the sun, mountain, water, cloud, rock, pine tree, elixir plant, tortoise, crane and deer. each subjects symbolizing longevity had used in isolation. unlike China and Japan, the ten symbols of longevity became a fixed form and was widely used in paintings, household effects and clothes in Korea. therefore, It will be a meaningful study how the ten symbols of longevity, as one of subjects in painting, changed into a pattern on clothes. The ten symbols of longevity was affected by various philosophies and religion. especially, it laid emphasis on order by Yin-Yang and the Five Elements theory. the order was applied to arrange each subjects and use colors carefully. the sun colored with red and was on the upper. the pine tree colored with green meaned tree and was on the left. the earth and the mountain meaned the soil and was on the center. the rock meaned the iron and was on the right. the water meaned the water and was on the bottom. The subjects of the study were embroideries like spectacle cases, spoon cases and pouches. the scope of study was the Latter Part of the Joseon Dynasty because there are more relics in the Joseon Dynasty than any other times.
