Yongneup wetland protected area, the only high moor in Korea, is a core area to conserve biodiversity. Even though the Yongneup wetland protected area is relatively small, various plant species are distributed in the Yongneup wetland protected area because it includes various habitats showing different environmental gradients. Vascular plants distributed in the Yongneup wetland protected area were identified as a total of 376 taxa that is composed of 73 families, 217 genera, 322 species, 3 subspecies, 44 varieties and 7 forms. For endangered plants designated by the Ministry of Environment, 5 species including Trientalis europaea var. arctica, Lilium dauricum, Halenia corniculata, Lychnis wilfordii and Menyanthes trifoliata were found and 34 taxa were confirmed to be distributed only in the mountainous wetland habitats. Regarding naturalized plants, a total of 11 taxa were distributed, but most of them were distributed in the areas where artificial interference has occurred. And in areas inside the wetlands that are relatively well preserved, 2 species of Bidens frondosa and Erigeron annuus were observed. In this study, the occurrence and distribution of Pseudostellaria baekdusanensis M. Kim, which was recently found in Mt. Baekdu and reported as a new species, were identified in the Yongneup wetland protected area. A wetland is a very vulnerable area to drastic environmental changes and damages to its ecosystem could cause the extinction of rare plant species which are distributed only in the wetlands. Therefore, it is mandatory that current status of the Yongneup wetland protected area is evaluated and actions to prevent rapid environmental changes are taken. Fourteen separate investigations were conducted in 2013 and another four in 2014, to evaluate current status of the Yongneup wetland protected area. These investigations have provided us the basic information for future actions of conservation and restoration.

The Balanced anesthesia has many benefits such as no air pollution, no hepatic or renal toxicity and postoperative pain relief compaired with inhalation anesthesia. The Study pointed out differences of cardiovasular change, serum glucose and cost among Inhalation (Enflurane), Propofol and Midazolam-Fentanyl. Thirty-three patients of ASA class I or II scheduled to undergo elective operations were classified randomly into 3 groups. Enflurane group(E) was induced with thiopental sodium 5.0mg/kg and maintained with 1.5-2.0 vol% Enflurane and 50% nitrous oxide. Propofol group(P) was induced with propofol 2mg/kg and maintained by the continuance of a intravenous infusion of propofol 6mg/kg/hr with which is supplied 50% nitrous oxide. Fentanyl group (F) was induced with midazolam 0.1mg/kg and fentanyl 4g/kg and maintained by the continuance of a intravenous infusion of fentanyl 4-6 g/kg/hr and midazolam 0.2mg/kg/hr with which is supplied 50% nitrous oxide. The results were as follows : 1. Systolic arterial pressure was increased significantly in two group (E & P group) at 1 min. after intubation (p<0.01) and decreased in three groups (E,P & F) at 10 min. after intubation (p<0.05). 2. Diastolic arterial pressure was increased in E group at 1 min. after intubation (P<0.01) and decreased in P group at 5 min., 10 min. after intubation (p<0.05). 3. Heart rate was significantly increased in E group at 1 min., 5 min. after intubation and P group at 1 min. after intubation (p<0.05). 4. Serum glucose was significantly increased in three groups at 60 min. after skin incision (p<0.01). 5. Cost was lower in P group than E and F groups.

Storage mites are believed one of the most important allergens in farmers and rural regions. Tyrophagus putrescenitiae, belonging to storage mites, is found not only within storehouses but also in the house dust, and the third most common mites following Dematophagoides farinae and Dermatophagoides pteronyssnus in house dust in Korea. The sensitization rate to Trophagus putrescentiae was reported as high as that of house dust mite in patients visiting the allergy clinic in large cities in Korea. We experienced a 69-year-old man who had suffered from dyspnea, wheezing, and coughing for 10 years. He retired from the teaching profession, and had lived in a large city. Deajeon. The skin prick test showed a positive reaction to Tyrophagus putrescentiae and negative reactions to house dust mites. The bronchial challenge test with Tyrophagus putrescentiae showed late asthmatic reaction. We confirmed a Tyrophagus putrescentiae induced asthma in non occupational setting.

Normally at a flood season the operation of the dam depends on a short range weather forecast that makes many difficulties of the management at a dry season. It is needed to study the pattern of the long period rainfall. The concept of PMP(Probable Maximum Precipitation) was used for designing dam. From the concept, this study is applied the concept of monthly probable maximum precipitation for operating dam. It can be possible to let us know the appropriateness of a limiting water level at a rainy season. For the operation of dam at a dry season this study can predict roughly the flood season's pattern of precipitation by month or period, therfore the prediction of precipitation can rise efficient operation of a dam.

Background and Objectives : The overexpression of P-glycoprotein (Pgp) or multidrug resistanceassociated protein (MRP) confers multidrug resistance (MDR) to cancer cells. MDR cells could be sensitized to anticancer drugs when treated concomitantly with a chemosensitizer. In this study, orange peel have been screened for the development of chemosensitizers reversing MDR. Materials and methods : Expression of Pgp in AML-2/WT and AML-2/D100 were determined using western blot analysis and RT-PCR. Candidates for chemosensitizers were isolated, purified from orange peel using sephadex LH-20 column chromatography and silica-gel column chromatography, whose structure was determined using ^1H-NMR, ^13C-NMR, ^1H-^1H-COSY, 13C-NMR, EI-Mass, IR. Chemosensitizing effect of NP-28 on AML-2/DX100 over expressing Pgp and MRP was determined by the MTT assay. Membrane toxicity was evaluated by the RBC hemolysis test. Antioxidant effects were examined by using a fluorescence probe (2’-7’-dichlorofluorescein diacetate). Results : A potent candidate, NP-28, has a flavonoid nucleus with some methoxy moiety. NP-28 is believed to have high therapeutic index, being non-transportable inhibitor and possibly, of inhibiting other efflux pumps such as MRP and antioxidant effects. NP-28 is also unlikely to be a substrate of Pgp. NP-28 did not increase Pgp levels. Conclusion : NP-28 has a Chemosensitizing effect to reverse Pgp-mediated MDR by increasing the intracellular accumulation of drugs. Furthermore, they do not increase expression of Pgp, which can allow a long term use without the concern about Pgp activation. NP-28 is anticipated as an ideal second-generation flavonoid chemosensitizer and/or possibly other therapeutic agents by further investigation.
