  • This study describes the effect of myo-inositol on sustained cell division and plant regeneration from cotyledon-derived protoplast of cabbage (Brassica oleracea var. capitata). Freshly isolated protoplasts were cultured in modified Murashige and Skoog (MS) medium removed ammonia ions and containing $0.4\;mg\;l^{-1}$ thiamine HCl, $100\;mg\;l^{-1}$ myo-inositol, $2\;mgl^{-1}$ 2,4-D, $0.5\;mgl^{-1}$ BA, $30\;gl^{-1}$ sucrose and several concentrations of myo-inositol (2, 4, 6, 8, 10% (w/v)) as an osmotic stabilizer. After 3 weeks of culture in the dark at $25^{\circ}C$, the plating efficiency of cabbage protoplasts reached to $22.5{\pm}2.9%$ when cultured in modified MS medium supplemented with $2\;mgl^{-1}$ 2,4-D, $0.5\;mgl^{-1}$ BA, $30\;gl^{-1}$ sucrose and 8% (w/v) of myo-inositol at a density of $2{\times}10^5$ protoplasts/ml. Rapidly growing cell colonies after 3 weeks of culture were transferred to the same culture medium removed osmoticum. To induce shoot regeneration from calluses, calluses with about 2 mm in diameter were transferred to the MS medium containing $2\;mgl^{-1}$ BA and $0.5\;mgl^{-1}$ NAA. After further three weeks of incubation onto the medium in the light, green shoots were formed on the surface of calluses at a frequency of 30%. Upon transfer to half-strength MS basal medium, roots were formed onto the bottom of regenerated shoots without auxin treatments. These regenerated plantlets were successfully acclimatized to soil transfer, grown to normal mature plants. The cabbage protoplast culture system established in this study could be applied for production of somatic hybrids or cybrids by asymmetric protoplast fusion and mass proliferation of elite somatic clones of cabbage.

  • The study was performed to investigate the characteristics of charcoal and temperature change of a kiln's inner and outer walls in carbonization process using improved kiln. In this kiln system, carbonization process was completed in eight days. In the kiln, the ignition temperature was kept about $720^{\circ}C$. And then the temperature were increased gradually prior to be refined. Finally, the temperature in refining process was reached to maximum point, $1,000^{\circ}C$. In the chimney, the temperature was increased gradually from $90^{\circ}C$ at ignition to $750^{\circ}C$ at refining. The temperature change of the kiln wall resembles a temperature change progress curve during a carbonization process. The highest temperature of the kiln wall that appeared by a carbonization process was around $500^{\circ}C$. As a result of having measured an inner wall and the outer wall of the kiln using an infrared thermography camera, it was judged with there being considerable latent heat on kiln wall and ceiling. Fixed carbon contented of charcoal was 85.9~89.9%. Refining degree of charcoal, hardness, calorific value and pH were l, 12, 7,047~7,456 kcal/kg, 9.0~9.9, respectively. The yield of wood charcoal was 13.8%, and compared to conventional kiln's yield increased 1.5%.

  • The geological structures and some of the stratigraphy in the area studied are being thought to be ambiguous and controvertible. The present study intended to clarify these ambiguities by correct interpretation of the geological structures and lithostratigraphy of the area concerned. The so-called "Sambangsan formation", which was designated as an unknown age by the Taebaksan Geological Investigation Corps (1962) and as the mid Cambrian age by T. Kobayashi (1966) and I.S. Kim (1983), has been determined by the present study as the $Hongj{\breve{o}}m$ series of Carbo-Permian age resting unconformably on the Cambro-Ordovician limestone formations. This determination was supported by conodont study concurrently carried out by I.S.Kim. The so-called "Daehari formation", which was renamed by the later study group after the original "Sambangsan formation" distributed in the area from southwest of Sambangsan toward southwest to $Juch{\breve{o}}n$, possesses more or less the same lithlogy as "Sambangsan formation" of the old designation in the eastern of the area, but different lithology in the western localities where Sadong formation, the basal sandstone member of the Kobangsan formation and the green shale member of the Nokam formation are cropped out. The narrow belt of the complex mixture of the $Py{\breve{o}}ngan$ group in-between limestone formations extending over 16km with a width of 500m to 1000m was formed by the faults: the northern boundary with the limestone formations is a fault contact all the way through entire area and the southern boundary is either fault contact in most of the area and unconformity in some other area. The $Hongj{\breve{o}}m$ formation on the Mt. Sambangsan shows rather steeply dipping nearly isoclinal folds which plunges $10^{\circ}$ to $20^{\circ}$ southward. There are also field evidences that the limestone formations distributed in both north and south of the Hongjom formation (erstwhile "Sambangsan formation") along the Sambangsan ridge are the same formations and show the same folding as the $Hongj{\breve{o}}m$ formation. Therefore, these limestone formations should be rezoned in the light of the new structural interpretation although they were differently designated in the previous studies as $Py{\breve{o}}ngchang$ and $Y{\breve{o}}ngw{\breve{o}}l$-type of the Joson Group. The structures developed in the area mostly faults, which acted as one of the guides for the new interpretation of the geology and structure of the area are described and shown on the geologic map.

  • recently, world is progressing large quantity consumption with continuous Innovation and economic growth and pollution is accelerated at these process. Increase of industry activity and service that is point of corporation activity is discharging environmental pollutants at whole process to manufacture of end product and exhaust process from acquisition of raw material for accompanied product production hereupon. At the same time, being promoting resources consumption by that use much raw material, As a result, is becoming obstacle factors in sustainable development. So, corporation's responsibility for environmental protection is emphasized. Corporation which must prepare in green round or environmental problems should consider environmental effects that is happened over whole life of products that include waste treatment after raw material acquisition and use as well as selling end product simply. A Life Cycle Assessment techniques is normalized and standardized in International Standard Organization for technical committee 207(TC 207) world widely, and effort to apply in corporation's activity because mastering LCA techniques in domestic several corporations is undergone actively. Coming into effect of Kyoto's Protocol and International Organization for Standard 14000 series revision are presenting new survival principle in competition between country or corporation. LCA technique may become very useful means to corporation which wish to attempt environment management in real condition that awareness for environment is important. Also, An LCA to each product is going to cause big effects in corporation's whole image as well as competitive power raising for single product. Therefore, this research wishes to examine some instances for the future competitive product development at the estimation of environmental friendliness using LCA techniques and more theoretical considerations of the LCA techniques that can dominate corporation's fate.

  • This study was conducted to investigate the physicochemical quality properties of oriental melon pickles harvested after pollination (green and fully ripe period) and soaking (cured and ripened). After the increase of the pollination size of melon, at 21 days, melon had a strong yellowish color, but at 24 days, its tip was completely yellow. In addition, 21 days after 5 days soaking, the weights of the harvested melons were reduced. Since then, there were no remarkable changes in weight. At 27 and 30 days, the b values of the melons that were harvested showed no trace of influence by the number of days of soaking and ripening. The melons harvested after 24 and 27 days, and the oriental melon pickles, maintained a constant hardness and texture after five days of soaking. This result indicates that melons harvested between 15 and 27 days after pollination can be used for melon pickles. To produce high-quality melon pickles with a yellowish color and a chewy texture, melons harvested 27 days after pollination and then soaked and ripened in salt water for 15 days should be used.

  • This study observed changes of understory vegetation to evaluate the role of forest aggregate after 15% aggregated retention harvest in mature oak forest (> 100 years) in Gyungsangbukdo Bonghwagun in 2010 and 2011. Spontaneous responses of understory vegetation cover (%), species richness, abundance of plant growth forms (herbaceous and woody plants), and overall attributes (by Ordination analysis) were estimated in aggregate area (0.15 and n=36) and clear cut area (0.85 and n=192) in experimental site and control site (1 and n=300). Based on ordination analysis, overall change of species composition in aggregated sites were relatively lower than in harvest area. Right after treatment, total cover of cutted area slightly decreased from 15.6% to 14.7%, and species richness increased from 14 species to 22 species. Cover and richness in the both of aggregate and control sites increased. In plant growth forms, 15% aggregate harvest revealed positive effects on the abundance (cover and richness) of herbaceous plants than woody group. After retention treatment, overall, edge effect likely played major component of vegetation changes in aggregate forest and in harvested area, mechanical damage from harvest operation and change of forest structure by clear cutting were critical. As pre-treatment data, which are rare in ecological studies in Korea, were critical for interpretation between patterns that may have arisen from spatial distributions in the original forest, our experimental design have higher opportunity for long term monitoring on the effect of forest aggregate and vegetation regeneration in clear cutted area.

  • This study was conducted to investigate the characteristics of bird community and to suggest a proper way how to manage and protect bird community in Mt. Paldal, Suwon City. The survey was carried out by line transect method from March 1992 to February 1993, and from October 1998 to August 1999. Twenty-seven birds were recorded, and these birds were also classified into 14 species for residents, 8 species fur summer visitors, 4 species for winter visitors and 1 species fur passage migrant in 1992. Twenty-one birds were recorded, and these birds were also belonged to 16 species fur residents, 2 species fur summer visitors, 2 species for winter visitors and 1 species for passage migrant in 1999. In 1992, seasonal change of number of species and individuals showed a typical pattern of temperate deciduous forests, however, seasonal pattern in 1999 was somewhat differed from that of temperate deciduous forest. According to data of migration habits of bird community in same months, percentage of residents were higher in 1999 and that of summer visitors were higher in 1992. In guild analysis of breeding bird community, bush-nesting and foraging guild that utilize the bush layer as nest and food resources showed the decreasing number of species and individuals, also summer visitors did the same decreasing trends from 1983. Therefore, it should be suggest that protection of bush layer for inhabitation of bush-nesting and foraging guild and summer visitors, and it will be considered that construction of green net-work among urban forests such as Mt. Kwanggyo, Mt. Chilbo, Mt. Paldal, Mt. Sukgi and Mt Yeogi in Suwon City.
