본 연구에서는 특성화를 전제로 식물원마다 지역경관자원이 잘 반영되기 위한 방향제공과 식물원 조성 시 비교적 적은 예산과 인력으로 최대한의 효과를 기대하기 위해서 지역경관자원을 활용한 식물원 계획지표를 개발하고 중요도를 분석하고자 하였다. 그 결과 상위계층(1계층)에서는 ‘자연자원(0.624)’이 가장 높게 나타났으며, ‘역사문화자원(0.203)’, ‘사회자원(0.172)’의 순으로 나타났다. 중간계층(2계층)에서는 ‘문화자원(0.592)’, ‘생태자원(0.454)’, ‘역사자원(0.408)’, ‘공동체자원(0.408)’, ‘산림자원(0.400)’의 순으로 비슷하게 나타났다. 하위계층(3계층)에 있어서는 ‘식생(0.688)’, ‘마을전통(0.641)’, ‘축제(0.581)’, ‘숲(0.557)’의 순으로 나타났다. 전체적으로 볼 때 중요도가 높은 것은 ‘식생(0.195)’, ‘숲(0.139)’이 높게 나타났으며, ‘초지(0.058)’, ‘습지(0.056)’가 다음 순이었다. ‘마을전통(0.053)’, ‘산(0.052)’, ‘지형지세(0.050)’도 계획 시에 중요한 지표가 될 수 있다. 그 외 ‘마을 상징물(0.050)’, ‘전설(0.044)’, ‘축제(0.041)’ 등의 항목도 중요한 지표로 판단되었다. 따라서 지역 경관자원을 활용한 식물원 조성방향을 설정하기 위해서는 ‘자연자원’의 ‘생태자원’, ‘산림자원’과 ‘역사자원’의 ‘마을전통’과 ‘문화자원’의 ‘전설’, ‘마을 상징물’과 ‘사회자원’으로서의 ‘축제’ 등이 중요한 계획지표라 할 수 있다. 따라서 지역경관자원을 활용한 식물원의 계획 시 기존의 자연자원 뿐만 아니라 지역의 정체성을 담을 수 있는 역사문화자원과 함께 사회자원을 수용할 수 있는 노력이 수반되어 할 것으로 사료된다.

To investigate optimal condition of acid-catalyzed hydrothermal hydrolysis of Laminaria japonica, the main constituentsof Laminaria japonica such as cellulose, alginic acid and mannitol were hydrolyzed using acid-catalyzed hydrothermalreaction. Then, we proposed the re-designed experimental method including the predicted optimal conditions of the mainconstituents and performed acid-catalyzed hydrothermal hydrolysis of Laminaria japonica. The coefficients ofdetermination (R2) of Y5 (yield of reducing sugar from Laminaria japonica) were 0.877. P values of Y5 were 0.002,indicating significance, within 1% (p<0.01). The optimum reaction condition for acid-catalyzed hydrothermal hydrolysisof Laminaria japonica determined by the response surface methodology is 143.65oC of reaction temperature, 22min ofreaction time, hydrochloric acid concentration 0.108N, resulting in a production rate of 115.62mg/g-Laminaria japonica.

This study aimed to investigate the optimal enzymatic hydrolysis conditions of alginic acid using Viscozyme® L, Celluclast® 1.5L, Saczyme®, Novozym®, Fungamyl® 800L, Driselase® Basidiomycetes sp., and Alginate Lyase, for production of reducing sugar. Response surface methodology (RSM) based on central composite rotatable design was used to study effects of the independent variables such as enzyme (1-9% v/w), reaction time (10-30 h), pH (3-7) and reaction temperature (30-70oC) on the production of reducing sugar from alginic acid. The coefficients of determination (R2) of Y1, Y2, Y3, Y4, Y5, Y6, and Y7 for the dependent variable regression equation were analyzed as 0.947 0.968, 0.840, 0.926, 0.923, 0.892 and 0.825. And the p-value of Y1, Y2, Y3, Y4, Y5, Y6, and Y7 within 1% (p < 0.01) was very significant. The optimal conditions were 1.0% of the quantity of the enzyme, 10.0 hours of the response time, pH 3 and 70.0oC of the reaction temperature, where the production rate was 483.1 mg/g-alginic acid, the highest of all the enzymes used.

Acid hydrolysis of cellulose using hydrothermal reaction was conducted to maximize reducing sugar concentration and the response surface methodology (RSM) was applied to study the effects of independent variables, such as reaction temperature (116 ~ 184oC), reaction time (12 ~ 28 min) and hydrochloric acid concentration (HCl, 0.0159 ~ 0.1841 N) on reducing sugar concentration and production yield from the cellulose. With the optimum conditions of the acid-catalyzed hydrothermal hydrolysis, the reducing sugar (RS) was obtained as 369.14 mg-RS/g-cellulose in 172.77oC of the reaction temperature, 28.41 min of the reaction time and 0.067 N of the hydrochloric acid concentration. The glucose (Glu) was obtained as 281.94 mg-Glu/g-cellulose in 154.70oC of the reaction temperature, 11.59 min of the reaction time and 0.184 N of the hydrochloric acid concentration.

The relationship between debris flow and topographical factors is essential for the reliable estimation of soil loss. The objective of this paper is to estimate stability index and soil loss for assessing landsliding risk caused by debris flow. SIMAP and RUSLE are used to estimate stability index and soil loss, respectively. The landsliding risk area estimated by using SIMAP is found to be different from the large land area estimated by RUSLE. It is found that the spatial distribution of soil cover significantly influences landsliding risk area. Results also indicate that stability index and soil loss, estimated by soil cover factor, improve the assessment of landsliding risk.

본 연구에서는 현재 소비문화공간으로 대표되는 신사동 가로수길, 삼청동, 서래마을의 세 곳을 중심으로 나타나고 있는 용기정원을 조사, 분석하여 장소에 따른 용기정원의 특성을 살펴보고자 하였다. 그 결과, 신사동 가로수길은 초기 패션과 디자인 계열이 입점했던 것에서 영향을 받은 패션업종에서 가장 많이 나타났고, 원형의 테라코타 용기에 상록과 그린색의 식물을 이용하여 입구에 가장 많이 위치시켜 동선을 유도하며, 패션소품으로 활용하였다. 삼청동의 경우는 오래되고 규모가 작은 공간에 활력을 불어 넣기 위해 모든 업종에서 고루 나타났고, 목재의 직사각형의 용기에 분홍색의 초화류를 이용하여 전면하부에 많이 위치시켜 밝은 분위기를 조성하였다. 서래마을의 경우는 프랑스마을의 장소성과 관련하여 야외 테라스의 카페와 레스토랑에서 많이 나타났고, 걸이와 벽면에서 난색계열의 초화류와 덩굴식물을 주로 이용하였다. 장소는 문화적이고 지역적인 것을 기반으로 하여 나타나는 맥락적 의미로 현재 소비문화공간에서 활발하게 조성되는 용기정원의 특성 또한 영향을 받고 있으며, 이것은 다시 장소성을 만드는 데 중요한 역할을 하고 있다. 차후에 이용고객을 대상으로 용기정원이 재방문에 어떤 영향을 미치는지와 장소성 형성에 어떤 영향을 미치는지에 대한 연구가 계속 진행되어야 할 것이다.

Sugar, starch and lignocellulosic biomass has been mainly used as raw materials for the production of the bioethanol. However, the sharp fluctuation of grain prices, a threat of world famine, and hardly biodegradable substance like lignin contained in lignocellulosic materials make the pre-processing of the biomass complicated in several aspects. As a result, the focus of attention has now shifted to the ‘third biomass’ such as algae, which has a high value of energy recovery. In this study, a kind of macroalgae and its characteristic were surveyed and then, the physical, biological, chemical, combined, and hydrothermal pretreatments for its hydrolysis were deeply considered. Consequently, the macroalgae could be more effectively hydrolyzed at the combined process such as the hydrothermal-chemical or biological treatment, chemical-biological treatment and so on than the single process like the biological pretreatment.

The layer technique is to produce many memorable scenes by generating layers of new experiences on the existing ones as it is adding the cognitive layers on to the visually seen landscape. Its need is high for places whose landscape itself influences perception, value or expression and which determines the spatial and quality standards. The existing floor plan-based design methods have failed to be useful in generating complex visual experiences. In order to maximize the aesthetical landscape experiences in landscape planning, cognitive layers are needed which complement the input of adequate cognitive elements and the inter-element relationships. Here, layers are utilized to change the arrangement of the landscape elements and coordinate the cognitive flow so that the images could be connected and imagination could occur. A case in point is Anhyun Village in Gochang where physically distinctive layers are additionally set to make a visual experience enriching. The new landscape layers discover the fact that it provides diversity in experiencing the village landscape and forming the sense of beauty and that it is deeply immersed into the daily life of the village. Meanwhile, Guwau Village in Taebaek is an example showing the usefulness of various-layer setting in landscape planning in setting effective circulation planning. That is, the bottom line is the spacing-starting where and making it stay where for a few seconds, and the visual layers. It is also critical to encourage inducing circulation so that layers of the senses stimulating five senses could intervene. Lastly, Mulgeon-ri in Namhae is a case which directly made a parallel of the physical layers of the landscape composition and the cognitive layers of the landscape experience. Artificial landscape planning is mostly about manipulating of visual traits that people feel beautiful, but the layer technique is linked to how to make experiences enriching and renewed.
