종의 棲息密度가 낮아지고 있는 하늘나리, 섬초롱, 자란 3종의 식물을 인위적으로 棲息地를 造成하기 위하여 국립공원 속리산 등산로변 標高 200m, 400m, 600m 지점에 150주식 종당 450주를 조직배양 및 분주에 의하여 육묘 된 묘를 이식하여 생존상태 및 棲息地 造成의 가능성을 2년에 걸쳐 검토한 결과는 다음과 같다. 1. 造成 棲息地의 토양의 理化學的 造成은 pH 5.2∼5.6, 유기물 함량 29∼54g/㎏, CEC 9.4∼11.5㎝ mol(+)/㎏으로 산성을 띠고 있었으며, 유기물 함량은 높은 편이었고, 염기치환용량은 낮았으나 비교적 우리나라 典型的 山地土壤의 理化學的 造成과 유사하였다. 2. 棲息地內 생장기간의 投光率은 標高 200m 지역은 10.8∼11.6%, 400m lw역은 10.8∼11.4%, 600m 지역은 11.0∼12.8%로 식재식물의 生長環境에 부족한 상태였다. 3. 식재 식물 수는 식재 후 활착율은 3종 모두 양호하였으나, 점차 감소되었으며, 특히 자란의 감소율이 높았다. 감소의 원인을 분석한 결과 하늘나리, 섬초롱, 자란 모두 굴취나 절취의 피해가 많았으며, 특히 자란은 凍害에 의한 枯死가 1년차 72∼86주, 2년 차에서 19∼35주로 조사도어 자연상태에서의 越冬은 어려운 것으로 나타났으며, 집중호우에 의한 流失도 감소의 한 원인이었다. 4. 식재식물의 생장상태는 불량하였는데 이는 投光量 부족으로 판단되어 棲息地造成時에는 錄陰期 投光量에 대한 사전 검토가 중요한 요인으로 나타났다. 5. 개화율은 섬초롱과 자란에서 높았으며 標高가 높을수록 개화기는 2∼4일 늦어지고 휴면기는 빨라지는 경향이었다. 식물 棲息地 造成時에는 造成 식물의 생장에 적합한 토양, 光環境 등을 고려한 위치 선정이 중요하며, 上層林에 의한 遮光으로 下層 초본식물 遷移速度가 빨라짐으로써 光環境 개선을 위한 上層林의 間伐, 周邊樹種의 更新이 요구된다. In order to make the artificial habitats of Lillium concolor, Campanula takesimana and Bletilla striata that the number of plant became sparse, 150 plants per species were transplanted at the region of 200m, 400m and 600m above sea level. And the growth of plants and the potential as habitats creation were analyzed. In the physical and chemical properties of soils in the there, soil pH was 5.2 to 5.6, organic matter content was 29 to 54g/㎏ and cation exchange capacity(CEC) was 9.4 to 11.5㎝ mol(+)/㎏. The transmittance rates of sunlight of the habitats during the growing periods were 10.8 to 11.6% in the 200m region, 10.8 to 11.4% in the 400m region and 11.0 to 12.8% in the 600m region. These transmittance rates were deficient for normal growth of plants. After the plants were transplanted, the survival rates of three species were high in common but the rates decreased gradually. Especially the decrease rate was high in the Bletilla striata. The causes of decrease were digging and cutting by climbers, sweeping asay by rainfall and freezing damage. Especially, the cold tolerance of Bletilla striata was weak in the natural condition. The growth of planted plants was poor, and it was assumed that the reason was shortage of sunlight transmittance. The flowering rates were high in the Campanula takesimana and Bletilla striata. And as the elevations were high, the flowering was later by 2 to 5 days but the dormancy was earlier. In the artificial making of plant habitats, the growth environment of plants have to be considered to choose the suitable region. And, because the habitats are shaded by the trees and bushes, the thinning of trees and the change of species are needs to improve the light transmission.

The dried roots of Rehmannia glutinosa(RG) have been used in the traditional medicine for treatment of diabetes, fever and dysuria, etc. In order to investigate the quality evaluation of the dried roots of RG, we conducted the physico-chemical and biological evaluation method. The amount of catalpol from commercial samples is very diverse about 0.00~3.89% by using HPLC method, because it is easily decomposed by processing of RG. So, we should try to identify the correlation with the contents of catalpol and biological activities of RG. We chose 3 samples which were a wide difference of catalpol contents between each sample(Sample-I; 3.4%, Sample-II; 2.8%, Sample-III; 0.05%). Sample-I and Sample-II were found to be more effective than Sample-III on the DPPH free radical scavenging effect and inhibitory effect on H₂O₂-catalyzed lipid peroxidation in rat liver in vitro. And, Sample-I and Sample-II exhibited more significant effects than Sample-III on accelerating actions of the small and large intestinal transport, and diuretic action in mice. So, it is suggested that the quantitative determination of catalpol should be required for the standardization of the dried roots of RG.

The amount of catalpol from commercial samples is very diverse about $0.00{\sim}3.89%$ by using HPLC method, because it is easily decomposed by processing of RG. So, we should try to identify the correlation with the contents of catalpol and biological activities of RG. We chose 3 samples which were a wide difference of catalpol contents between each sample (Sample-I; 3.4%, Sample-II; 2.8%, Sample-III; 0.05%). Sample-I and Sample-II were found to be more effective than Sample-III on the DPPH free radical scavenging effect and inhibitory effect on $H_2O_2-catalyzed$ lipid peroxidation in rat liver in vitro. And, Sample-I and Sample-II exhibited more significant effects than Sample-III on accelerating actions of the small and large intestinal transport, and diuretic action in mice. So, it is suggested that the quantitative determination of catalpol should be required for the tandardization of the dried roots of RG.

On 16 April 2014, the Sewol ferry, carrying 476 people, sank in the ocean off the south coast of South Korea. Two hundred and ninety five are confirmed dead and 9 remain missing. The Korean Neuropsychiatric Association (KNPA) set up a Disaster Mental Health Committee (KDMHC) for out- reach services and to provide general strategies for promoting mental health and resilience. Mem bers of KDMHC and Volunteering Psychiatrists of the KNPA had participated in disaster mental health services organized by Gyeonggi- Ansan disaster mental health support team. Their activities were composed of psychoeducation, supportive individual and familial counseling and referring service to professional institutes. This report has described the outline of the initial and acute mental health care responses by KDMHC and volunteers among KNPA members.

In this study, the electrochemical and mechanical durabilities of two types of cast membranes and a reinforced composite membrane based on sulfonated poly(arylene ether sulfone) were evaluated by OCV test and wet-dry cycle test. The composite membrane with electrospun microporous polyimide substrates showed higher mechanical stability than the cast membranes. Also, the higher the molecular weight of polymer membrane, the greater the electrochemical stability.

The quantity of leachate from Sudokwon landfill site was found to increase 30% in the rainy seasons than in dry seasons. With regard to water quality, BOD(Biochemical Oxygen Demand) was found to rapidly decrease to about 270 mg/L in 2001 when the landfill was completed from about 7,000 mg/L in 1993, one year after landfill started. On the other hand, nitrogen was found to gradually increase from about 600 mg/L in 1993, up to 2,200 mg/1 in 2000 when the landfill was completed.. As a result of operating denitrification and nitrification process, the organic material showed treatment efficiency of about 99% for BOD and 94% for COD<sub>Cr</sub> at MLVSS of 7,000 ~9,000 mg/L, HRT of 6.3 days, and water temperature of about 30~40℃. Nitrogen showed stable treatment efficiency of over about 80% for T-N and about 99% for NH₄<sup>+</sup> -N at C/N(BOD/NH₄<sup>+</sup>-N) of over 3.0 and return ratio of about 7Q in addition to above conditions. As a result of operating coagulation process, it showed the treatment efficiency of about 55% when concentration of FeCl₃ was maintained at about 400 mgFe<sup>3+</sup>/L. As a result of operating fenton oxidation, fenton reagent concentration was about 140 mgFe<sup>2+</sup>/L, 100 mgH₂O₂/L in consideration of color and economic feature of discharge water. In this regard, proper concentration of reagent(Fe<sup>2+</sup>/H₂O₂) was found to be about 1.4.
