  • To accomplish the greenhouse gas reduction which is over core unit project of the "Green growth" policy and "Resource circulation society", it is important to maintain proper balance and complement between energy recovery from waste and material recycling. This research(study) examined the related policies on the past of korea and foreign country, and also "The 4th resource recycling master plan" and "Energy recovery from waste plan" to provide advisable direction for resource recycling policy. The results of the research(study) showed that there were no significant difference between korea and developed foreign countries waste management policies. But in German policy, energy recovery from waste and pre-treatment are importantly considered and highly required for permission. Under current circumstance in korea, recycling will be more difficult than in the past. According to "The 4th resource recycling master plan", film type of synthetic resin was not sustainable recycled material in substance."Energy recovery from waste plan", proved that the energy recovery from RDF/RPF have lower efficiency than regular incineration generation and substance recycling. To solve these problems, the energy and remainder heat recovery must be generalized to "Energy recovery" concept and institutional improvement such as LCA(Life Cycle Assessment) system are need to support it. And also technology development to extract synthetic polymer by dissolved film type of synthetic resin must be provided.

  • PURPOSE: The purpose of this study was to evaluate whether light-emitting diodes (LED) irradiation could be effective in a noninvasive, therapeutic device for the treatment of osteoarthritis(OA). METHODS: Twenty-four male Sprague-Dawley rats were divided into four groups: Vehicle control (saline); monosodium iodoacetate-injection (MIA); LED irradiation after MIA injection (MIA-LED); indomethacin-treatment after MIA injection (MIA-IMT). OA was induced by intra-articular injection of 3 mg MIA through the patellar ligament of the right knee. Vehicle control rats were injected with an equivalent volume of saline. The LED was irradiated for 15 min/day for a week after 7 days of MIA treatment. To compare with the effect of LED irradiation, the indomethacin was administrated 20 mg/kg twice a week orally after 7 days of MIA treatment. Knee joints were removed and fixed overnight in 10% neutral buffered formalin and decalcified by EDTA for 2 week before being embedded in paraffin. The assessment of OA induction were monitored by knee movement and radiographic finding. Histologic analysis were performed following staining with hematoxylin and eosin, safranin O-fast green, or toluidine blue, picrosirius red, and histologic changes were scored according to a modified Mankin system. Apoptotic cell in tissue sections was detected using TUNEL method. RESULTS: Radiographic examination could not show the differences between the MIA-treated and the MIA-LED-treated rats. In the histologic analysis, however, LED irradiation prevented cartilage damage and subchondral bone destruction, and significantly reduced mononuclear inflammatory cell infiltration and pannus formation. LED irradiation also reduced apoptosis of cartilage cells, but it prevented apoptosis of infiltrated inflammatory cells in synovium. In addition, LED irradiation showed an increase of collagen production in the meniscus. CONCLUSION: These results suggest that the 840 nm LED irradiation would be a suitable non-thermal phototherapy for the treatment of OA, as a cartilage protection and anti-inflammatory modality.

A cross was made between 'Lilabella' and 'Mephisto' with purple and semi-double in 2005. After investigation of the characteristics for five years (from 2005 to 2009), it was selected specially as a cut flower. The 'Paspin' cultivar has a pastel pink flower color (RHS R52B) with green disc center and semi-double flower. It has large-sized flowers which average flower diameter is about 12.8 cm. And inner ray floret and disc diameters are 7.87 cm and 2.57 cm, respectively. It has an adequate peduncle height of 48.6 cm, and a longer vase life of 10.8 days. It is vigorous in growth and also adaptable to the local cultural environments of Korea. It is expected that if the 'Paspin' cultivar will be planted, the royalty fees to be paid to other countries can be saved. And the local growers will also be benefitted since the cost of cultivars will be lower than the imported ones.

  • Cypripediums, popularly called lady's slippers or moccasin flowers, are the showiest and most sought after hardy terrestrial orchids, collected and grown by orchid and alpine plant enthusiasts alike. In Korea, 4 species of cypripedium are reported as Cypripedium japonicum, C. macranthos, C. guttatum, and C. calceolus. We had already reported the feasibilities of C. macranthos and C. guttatum with in vitro germination methods from immature seeds. The seeds of white lady's slipper orchid (Cypripedium macranthos Sw. alba) were collected 65 days after pollination in 2018. The green pods were sterilized with flame and sowed immediately on the POM(Phytomax orchid maintenance media(R), Sigma) supplemented with BAP 0, 0.5, 1.0 mg/L and NAA 0, 1, 2mg/L. The germination of seed was observed 90 days after sowing, and the plantlets were subcultured to the same media according to the size of the protocorm with 1~2, 2~3, 3~4, 5~6, 7~8mm. The time of the subculture to the new media seems to be critical factors of forming rhizoids which is the hairy root of the cypripediums. As a results, the protorms of the white lady's slipper orchid was successfully germinated in the POM media supplemented BAP 0.5 and NAA 1.0 mg/L. The roots and rhizoids were formed in 5~6mm protocorms subculture over 95% survival ratio. We also tried to subculture to liquid medium without activated charcoal, however the browning or malformation of the roots was observed in the root. The formation of shoots from the protocorm was effectively enhanced in the POM media with non-additives of plant growth regulators. These results indicate the possibility of high and stable production and practical industrialization of endangered white lady's slipper orchids.

  • Tourist industry has many sensitive issues with climate change and is worthy of study from an aspect that it could provide new opportunities and threats from the low-carbon - green- growth point of view. To study how the change of awareness and attitude of the customers due to climate change affects the tourism demand and tourism choices is very important. Even at present, the effect is ongoing. In this paper, diverse needs and changes of tourists, who are the subjects of tourism activities, have been grasped through the examination of psychological characteristics according to climate change after defining the influencing relations of tourism experience, tourism value, tourism risk factors, satisfaction, and behavioral intention, affected by awareness of climate change and their attitude toward it. Through this, the implications that are necessary for establishing marketing strategies could be provided. The results of this present paper are as follows: First, it was shown that awareness of climate change did not affect tourism risk factors while it had a significant influence on tourism experience and tourism value. Secondly, it was revealed that the Chinese tourists generally influenced more greatly than the Koreans. Thirdly, it was shown that the attitude toward climate change did not affect tourism value while it influenced significantly on tourism experience and tourism risk factors. Fourthly, it was revealed that tourism risk factors did not affect tourism satisfaction while tourism experience and tourism value had a significant influence on tourist satisfaction. Fifthly and last, it was shown that tourism experience, tourism value, and tourism risk factors did not influence behavioral intention respectively.
