  • This stduy was attempted to establish the basic data for evaluating chemical components in the sap from birches(Betula platyphylla Sukatschev, Betula costata Trautv, Betula davurica Pallas), bamboos(Phyllostachys pubescens, Phyllostachys bambusoides, Phyllostachys nigra), Darae(Actinidia arguta). Calcium and potassium in five kinds of mineral detected in the sap were dominant mineral, magnesium, sodium and iron in order and calcium, potassium and magnesium are abundant in the sap from bamboo more than the other sample and the contents were 242.0~422.1mg/L, 793.8~ 2504.1mg/L and 72.6~165.9mg/L, respectively. Free sugars of the sap determined were glucose, fructose and sucrose, but maltose was not detected. The contents of glucose and fructose of the sap from Betula platyphylla Sukatschev(#2) were the highest and 42.1g/L and 36.9g/L, respectively. The detectabel nucleotides and their related compounds were CMP, UMP, GMP, IMP, AMP and hypoxanthine. The total contents of composition amino acids detected from eighteen kinds of the sap were in the range of 2.4~30.4mg%. The major amino acids were taurine, glycine, lysine, alanine and threonine in the sap from birch(#1, #2), glutamic acid and lysine in the sap from Betula costata Trauty(#3) and Betula davurica Pallas(#4), lysine, valine, alanine, serine, tyrosine and glutamic acid in the sap from bamboos, and glutamic acid, leucine, alanine in the sap from Darae.

  • 함정그물은 어살류와 낙망류로 나뉜다. 그 중 죽방렴은 고정목을 설치하여 어획하는 어구로서 어살류에 속한다. 죽방렴은 유속이 매우 빠른 남해안 협수로에서 이루어지는 어업으로, 날개와 발통 두 부분으로 구성된 어구이다. 어구의 구조는 해저에 돌을 쌓아올려 그 위에 고정목을 박아 V자형 날개를 설치하고, V자의 꼭지점에 해당하는 곳에 발통을 설치한다. 과거에는 발통 부분을 대나무로 엮어서 만들었기 때문에 죽방렴이라 했으나, 현재는 대나무 대신 망목 크기가 작은 그물을 발통 내부에 둘러싼다. (중략)

  • 홍조류의 일종인 우뭇가사리에서 채쥐한 섬유소로 제작된 종이(펄프)가 최근 서영범 충남대학교 임산공학과 교수에 의해 공개됐다. 지금까지 목재 펄프가 아닌 비목재 펄프에 대한 도전은 많았다. 볏짚, 사탕수수, 갈대, 대나무 등 주로 지상에서 채취되는 원료를 사용했는데, 해조류를 활용한 것은 지극히 예외적인 경우로 더욱 큰 관심을 불러일으키고 있다.

  • The Kong-Chung Jung's relics made of wooden materials were pre-examined for conservation. Kong-Chung Jung was a General of the Chosun Dynasty and his weapons were made of wood. The pre-examining method was focused on the quality and species of the wooden weapons. X-ray radiation was used for the observation of wood structure, and the condition of the relics was relatively good although they contained some cracks. The examination of species using optical microscope showed that the species of each relics were Pinus densiflora of hanging scroll pole, Lozoste lancifolia of a top of flagnole, Fraxinus sp. of a flagpole, Phyllostachys sp. of arrow shafts. For the conservation of the relics, celyl alcohol as dimensional stability chemicals was used and poly(vinyl acetate) and epoxy adhesives were also used for the joining and restoring of the relics.

  • In order to assess the spatial and dynamic changes in bamboo forests, this study used the national-level spatial data between 1980 and 2010 to extract spatial information of bamboo forests through GIS technology. The results showed that the distribution types were mainly expansion, normal, mixed, damage, and separation. In case of mixed bamboo forest in the Sacheon region, the expansion characteristics were: area 2.5 ha, velocity 0.08 ha/yr, and distance 1.1 m/yr. The Phyllostachys pubescens forest in the Geojae region showed the following characteristics: area 1.9 ha, velocity 0.06 ha/yr, and distance 0.9 m/yr with where along from valley to ridge. This approach could provide a valuable tool for decision-making and implementations such as the bamboo forest management plan, environmental impact assessment for a preventing the bamboo expansion, and sustainable managing the bamboo resources.

  • In the present study, safe management and value improvement of bamboo sunblind, which is an item of cultural heritage, were performed by adopting stable conservation treatment methods. The bamboo sunblind used in the present study was excavated from No. 1 catchment site in Baesanseongji, Busan. It was determined that the main material used to make the sunblind was bamboo, and herbal plants were used to weave the bamboo using lacquer as an adhesive agent. All contaminants and soil adhered to the sunblind was removed. Thereafter, the sunblind, which was recovered in the form of blocks, was washed separately after fixing it to a temporary plaster frame and to avoid the blocks from breaking during washing. Then, polyethylene glycol (PEG) impregnation was utilized for the reinforcement treatment. Based on the preliminary test results, the shape of the sunblind was fixed using a stainless-steel frame to prevent physical damage that may occur during the drying process. Thereafter, the bamboo sunblind was vacuum freeze-dried. PEG 20% (in ethyl alcohol) was applied as a surface treatment agent for stabilization the sunblind. After the surface treatment, the bamboo sunblind were joined together to fit the maximum width, and the rectangular shape of the sunblind was restored-as best as possible-while filling in the missing parts by maximizing the use of unknown members such as in the disturbed layers below bamboo sunblind surface. The conservation treatment was completed by fixing the bamboo sunblind into the fabricated frame.

  • Hexeneuronic acid in soda-anthraquinone(AQ) pulps from Moso bamboo(Phyllostachys pubescebs), Timber bamboo(Phyllostachys bambusoides) and Henon bamboo(Phyllostachys nigra var. henonis) was investigated with mercuric chloride hydrolysis and UV spectroscopic quantification. Concentration of hexeneuronic acid in bamboo pulps was $36.6-45.4{\mu}mol/g$, which contributed to 3.1-3.9 value increase of kappa number. Lower concentration of 4-O-methylglucuronic acid in bamboo xylan contributed to lower hexeneruonic acid content in bamboo pulps than those of hardwood(yellow poplar or eucalyptus) but higher than softwood(red pine).

  • This study was conducted to investigate optimal processing conditions, cooking characteristics, antioxidant activity and packaging method of rice coated with bamboo extract. In sensory evaluation of cooked rice, rice coated with bamboo ethanol extract was higher smell and taste than the other extraction methods, but texture showed no difference. As coating concentration increasing, L, a and b values of coated rice were increased. But L value of coated rice after cooking was decreased. On sensory evaluation of cooked rice, smell and taste were best in 10$\%$ coated with bamboo ethanol extract. Mineral contents of coated rice with bamboo extract were higher than those of uncoated. Water absorption and volume expansion of coated rice were lower than uncoated rice but showed higher toyo value. Hardness, gumminess and chewiness values of cooked rice with coated rice were higher than uncoated rice. Antioxidant activity of coated rice was higher than uncoated rice about twice times. Toyo values and alkali digestive values of coated rice were highest in paper package than the other packaging conditions. The total bacterial counts of rice coated with bamboo extract after cooking was lower than uncoated rice during storage at 25 and 6O$^{\circ}C$.
