Three major trails of campus forest in Chungnam National University were selected to investigate the use impacts on environmental deterioration of trail according to the different amount of use. Rook-exposed, root-exposed, deepening, widening, diverged points as the deterioration types of trail which were surveyed at total of 92 points in major trail of campus forest in Chungnam National University. Major deterioration types of trail were widening, rock-exposure, root-exposure, in order of frequency. And trail conditions(trail slope and maximum depth) of deteriorated points were significantly different from those of non-deteriorated points.

Objectives : Cinnamomi Ramulus (CR), the young twing of Cinnamomi loureirii nees, has been used for treating symptoms related to pain. rheumatic arthritis and inflammation in Korean herb medicine. This study was carried out to investigate the anti-inflammatory effect of CR in vivo and in vitro. Methods : Extracts of CR were prepared and the chemical components of the extracts were examined by gas chromatography-mass spectrometry (GC-MS). The extracts were administrated to the rat paw edema model induced by carrageenan to evaluate the anti-inflammatory effect of CR. The expressions of nitric oxide (NO). prostaglandin E2(PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 were also quantified in lipopolysaccharide (LPS)-induced RAW 264.7 macrophages to survey the effect of CR in vitro. The main components were cinnamaldechyde and coumarin. Results : We examined the anti-inflammatory activity of the 80% ethanol extract of Cinnamomi Ramulus in vivo by using carrageenan-induced rat paw edema model. Maximum inhibition of 54.9% was noted at the dose of 1000㎎/㎏ after 2 hours of drug administration in carrageenan-induced rat paw edema and this showed a potent anti-inflammatory effect. Conclusions : The results showed that Cinnamomi Ramulus suppressed dose-dependently LPS-induced NO production in RAW 264.7 macrophages and also decreased iNOS protein expression. Cinnamomi Ramulus also showed a significant inhibitory effect in LPS-induced PGE2 production and COX-2 expression.

본 논문에서는, 일반적인 스트립 구조의 결합기가 갖는 문제 즉, 높은 온도에서 나쁜 특성을 보이는 문제점을 극복하고자 Air Line Type의 결합기를 구현하였다. 또한 이 결합기는 24dB이상의 지향성을 가지고 있다. 해석을 위해 짝수 모드와 홀수 모드 해석법을 사용하였고, EM-Simulation으로 확인한 특성과 실제 제작된 20dB, 30dB Cellular 대역(800∼900MHz) Air Line 결합기의 결고 특성은 좋은 일치를 보여주고 있다. 또한 최대 장점인 온도 특성은 온도 데이터를 통하여 온도에 강한 특성을 보임을 알 수 있다.

생열귀나무의 잎에 대한 일반성분과 tocopherol 동족체를 분석하였으며, 생리활성 기능을 검색하기 위해 메탄올 추출물의 항산화력을 보다 더 정제하기 위해 헥산, 클로르포름, 에틸아세테이트, 부탄올 및 물충으로 분획하여 얻어진 추출물과 분획물을 이용하여 자외선(UV 308, 350 nm) 차단효과와 DPPH 자유라디칼 소거법에 의한 항산화성 효과를 검토하여 다음과 같은 결론을 얻었다. 일반성분의 분석 결과 수분이 67.5%로 가장 높게 나타났으며, 탄수화물 18.9%, 조단백질 6.8%, 회분 6.1% 그리고 조지방 0.7% 순이었다. 무기질 함량으로 가장 높은 것은 칼륨으로 1,637.2 mg%로 나타났다. 메탄올 추출물을 물로 현탁시킨 후 헥산, 클로르포름, 에틸아세테이트, 부탄올 순서로 용매를 분획하여 각각의 분획물을 얻은 결과 물(34.8%)이 가장 높게 분획되었으며, 메탄올 추출물을 각각 n-헥산, 클로르포름, 에틸아세테이트, n-부탄올 및 물 분획물을 얻어 자외선 차단효과를 측정한 결과 장파장대 (UVA 320∼400 nm)의 경우 에틸아세테이트 분획물(151.4)에서 가장 높게 측정되었다. 한편, 메탄올 분획물의 항산화 활성을 검토한 결과 에틸아세테이트 분획물의 항산화 홀성 (IC_(50) : 6.0 μg)이 가장 높았으며, 그 다음이 부탄올 분획물((IC_(50) : 14.0 μg)로 나타났다. The objective of this study was carried out to investigate nutritional characteristics and biological activities effects of Korean leaf of Rosa davurica Pall, in vitro. They were extracted with methanol and then further fractionated to n-hexane, chloroform, ethyl-acetate, n-butanol and water from methanol extracts. Methods of the antigenotoxic used in this experiment were UVA/UVB absorption property and DPPH radical scavenge. The proximate compositions of leaves of Rosa dauvrica Pall were 67.5% of crude Moisture, 0.7% of crude fat, 6.8% of crude protein, 6.1% of crude ash, and 20.8% of crude fiber. The major minerals were K (1637.2 mg%), Ca (219.5 mg%), and Mg(135.1 mg%). Most of the fractions of methanol extract which leaves of Rosa dauvrica Pall, have strong absorbency at UVB region (308 nm) and UVA region (350 nm). These fractions have a good absorbency property as synthetic filter and could be served as substitutes for synthetic UV sunscreen agents. All fractions (n-hexane, ethyl-acetate, n-butanol and water) from methanol extracts except chloroform fraction exhibited DPPH radical scavenging activity with IC_(50) of 35.3, 6.0, 14.0, and 18.0 μg/mL.

Objective : The use of herbal therapy is becoming an increasingly attractive approach for the treatment of various inflammatory disorders. The Alpiniae officinari Rhizoma is popular in Aisa as a traditional herbal medicine. Alpiniae officinari Rhizoma is a species of the ginger family(Zingiberacease). Method : This study was performed to investigate the anti-inflammatory effect of Alpiniae officinari Rhizoma extract by the methods of "carrageenan induced paw edema" and "Lipopolysaccharide-induced inflammatory mediators in mouse macrophage RAW 264.7 cells". Result : We suggest that Alpiniae officinari Rhizoma extract decreased paw volume induced by plantar injection of carrageenan. Also Alpiniae officinari Rhizoma extract inhibited nitric oxide, prostaglandin E₂production and induced nitric oxide synthase, cyclooxygenase-2 protein expression in Mouse macrophage RAW 264.7 cells stimulated with lipopolysaccharide. Conclusion : This study shows that Alpiniae officinari Rhizoma extract seems to have anti-inflammatory effect by inhibition of nitric oxide, prostaglandin E_(2) production and nitric oxide synthase, cyclooxygenase-2 protein expression.

Mt. Mudeung is considered as one of the important tourist attractions to satisfy Kwangju citizens as well as tourists so this study on provincial parks shows following suggestions to help the development of tourist resources and the preparation of recreation space. The conclusions are : First, in developing tourist resources, native and available resources should be considered in relation to local characteristics. And then tourist route, space for receation, and paths up the mountain should be provided, in connection with tourist attractions. Second, the landscape ought to be designed in harmony with surrounding natural forests, so that it can show both its unity and variety coming out of characteristics of the space. Third, after grasping functions and characteristics of Mt. Mudeung, the strategy for development should be made. Fourth, experts are required to take care of cultural resources. Firth, as the silent pattern of tour and recreation have changed into active one, resources to developed. Besides, convenience facilities should be repaired and newly made. Sixth, visitors' purpose and motivation show that Mt. Mudeung, provincial park, is being used as a nearby park. Seventh, it is to destory nature and the scenery that Mt. MuDeung provincial park is exploit the openspace of tourism and leisure. Consequently the development of openspace for social tourism and leisure is enough considered with natural environment and it is well planned to don't destory the ecosystem in order to play the important role of developed space and citizen's park.
