김선신의 『두류전지』 현전하는 유일의 지리산 지리서이다. 지리산권 문화 를 연구하기 위한 일환으로 『두류전지』를 중심에 둔 지리·불교·문학 등 다양한 분과별 연구가 기획되었는데, 이 글은 그 중 문학 분과의 연구 성과로, 『두류전지』 제11편 「貼山詩話」 속 한시를 중심으로 고찰하였다.
「첩산시화」에는 모두 100여 개 항목의 한시가 수록되어 있으며, 그중 온전한 체재를 갖춘 작품은 대략 80수이다. 이들 작품은 김선신이 집필에 활용한 『동국여지승람』 과 지리산권역 10개 지역의 읍지에서 선별한 것이다. 모두 50여 명 작가의 작품이고, 시기적으로는 삼국시대부터 조선중기까지이다.
‘첩산’이라는 말은 ‘지리산에 기대어 있는, 지리산의 주변이나 가장자리’를 뜻 한다. 이는 「첩산시화」에 수록된 작품이 ‘지리산’ 그 자체가 아니라 그 주변 사 람의 이야기를 담은 한시라는 의미이다. 「첩산시화」 속 한시 가운데 9할 이상이 지리산의 주변을 노래하고 있다.
「첩산시화」에 드러나는 김선신의 이러한 선별 의식은 여느 山誌의 체재와 비교해 보아도 매우 독특하다. 예컨대 『주왕산지』 나 』청량산지』에는 ‘題詠 또는 記錄’ 등의 제목 아래에 해당 산을 유람한 유람록과 유람시가 수록되어 있다. 그런데 『두류전지』에는 지리산유람록을 한 편도 실지 않았고, 유람시 또한 극히 일부에 불과하다.
이처럼 김선신이 ‘지리산’이 아니라 ‘지리산 권역’을 읊은 것은 그 속에서 지 리산과 함께 살아가는 인간의 삶과 문화를 드러내고, 그들과 함께 지리산이 지 닌 온전한 덕을 후세에 전하고 싶었던 의도라 판단된다.
Water management information system used by KRC(Korea Rural Community Corporation) operates widely including RIMS, RAWRIS and etc. Other systems are operated by each government department, for example, K-water(Korea Water Resources Corporation)’s WAMIS. Even though small scale reservoirs managed by city/country is just about 12% of total water resource, the reservoirs are important for controlling and securing water resource as the reservoirs, including about 14,700 reservoirs nationwide, are located at main subwater shed. So, it is necessary for KRC to execute integrated informatization. In this research, system analysis was performed to comprise the integrated water management information system including the reservoirs controlled by city and country at first. And then, improvement plan for informatization of the reservoirs controlled by city and country was proposed. This study proposed the improvement plan for informatization of the reservoirs managed by the city and country, which was systematically proposed through systemic analysis including from reservoir site to the integrated water management information system. The objects includes 1. Reservoir (basin, facilities, water depth-area curve, benefiter area), 2. Field supervision organization for the reservoir 3. Local government administrative organization, 4. Center organization 5. Network for information transfer, 6. integrated water management information system. As the reservoirs controlled by city and country are important considering managing water and facilities, operated by local government with minimum budget due to budget problem, securing sufficient budget is necessary to form an specialized organization controlling facilities and the water management system in terms of drought and flood control.
Due to the enlargement and high-rise of reinforced concrete structure, the application of high functional material is required. However, high-strength bar is recently introduced to the country and the material is insufficient to measure the variation of quantity of rebar quantitatively when using high-strength bar. For these reasons, this study is to provide useful data in cost decision making when applying high-strength bar at a stage of architectural project planning. For residence-commerce complex buildings, we set up six types of conditions such as in case of using only rebar, in case of using only high-strength bar, in case of using rebar mixed with high-strength bar and so on. With the standard of study model 1 that applies only SD400 regardless of rebar diameter, the analyzed result of rebar variation and the cost change of construction in other study model is as follows. When the rebar amount and cost in study model I was 100%, each ratio was 88.3% and 90.5% in study model II, 80.2% and 83.4% in study model III, 91.9% and 93.5% in study model IV, 88.9% and 87.7% in study model V and 82.4% and 85.5% in study model VI. Therefore, in case of rebar amount and construction cost, study model III was evaluated as the best that was applied only SD600.
This study was conducted to evaluate the effect of plant number per hill (PNH) on growth and yield of foxtail millet in drained paddy fields. Crop growth, development, and yield in the field were examined for 2 years to assess the efficiency of proposed cropping system. The greatest culm length of 138 and 148 cm in the first and the second year, respectively, at the harvest stage was observed in plots with one plant per hill. The greatest culm diameter of 7.79 and 7.67 mm in the first and second year, respectively, was measured in plots with one plant per hill. The greatest tiller number of foxtail millet in plots with one plant per hill was 2.9 and 2.7 in the first and the second year, respectively. However, there was no significant difference between plots with four and five plant per hill. Among the measured yield components, the spike length and seed number per spike were one plant per hill in both years. The highest grain yield of foxtail millet (324 kg ․ 10a -1 and 333 kg ․ 10a -1 in the first and second year, respectively) was obtained from plots with two plants por hill, followed by plots one, three, four, and five plants per hill.
Most of countries are trying to increase the supply of renewable energy as the substitute of the fossil energy for reducing greenhouse gas emissions. However, renewable energy sources account for only about 3.86% of the total Korea primary energy supply. To increase the rate of renewable energy in Korea’s energy consumption, various policies for expanding the use of renewable energy should be applied. Also these policies should be consider renewable energy resources distribution and regional inequality. In this study, the potentials of photovoltaic, wind power and bioenergy from rice straw, livestock waste and food waste are calculated and the distribution characteristic and regional inequalities are analyzed using Gini’s coefficient and Gini decomposition method. As the results, technical potentials of photovoltaic and wind power of city region(Gu) has more potential rate than theoretical potentials. Livestock waste has the most unequal distribution (Gini’s coefficient: 0.617) among renewable resources.
Ninety ducks (one-day-old Pekins, 45 males and 45 females) were used to evaluate the effects of supplementing diets with Houttuynia cordata powder on the fatty acid profiles of duck breast meat. The ducks were allotted to one of the three treatment diets using a completely randomized design, each treatment-group containing three replicate pens with ten birds each (five of each gender). The experimental diets were: 1) Control (basal diet), 2) T1 (Control+ 1% Houttuynia cordata) and 3) T2 (Control+2% Houttuynia cordata). In spite of significant difference, the addition of Houttuynia cordata resulted in higher unsaturated fatty acid and lower saturated fatty acid contents than in the Control group. However, no remarkable difference was observed between 1% and 2 % Houttuynia cordata groups for fatty acid profiles.
Background : Every year, Damping-off is repeated in the germination time of ginseng on April to May. This study was carried out to find out the cause of damping-off and the optimum eco-friendly product for suppression of damping-off caused by Rhizoctonia solani on Panax ginseng. Methods and Results : Bikona (Bioagent), Lime-Sulfur Mixture, Lime-Bordeux Mixture, NaOcl, and Fludioxonil were tested in farmer's field located in Youngju and Bonghwa, Gyeongbuk. Experimental plots (20m×0.9m) of 4-year-old ginseng fields were artificially infested with 2kg and 3kg in fresh weight of inoculum in Youngju and Bonghwa, respectively. Growth characteristics in all the plots of eco-friendly product were similar and had no difference significantly. Damping-off incidences were 0.8% at the polt of NaOcl in Bonghwa, which showed the lowest in all the plots. Ginseng yield in the plot of NaOcl and Fludioxonil were 1.75 kg and 1.71 kg per 1.62 ㎡, which increased 10∼12% compared to the control plot. Conclusion : Sodium hypochlorite as eco-friendly materials for control of damping-off caused by Rhizoctonia solani in ginseng represented a similar performance with Fludioxonil and seems to be utilized in the farm.
Background : The Ginseng has been one of the crops that represents Korea, and the main export items in the 1960s, Now it occupies the first exports of agricultural products. The Eco-friendly cultivation of Ginseng was difficult for various reasons. But the cultivation in Green House can be suppressed disease occurrence, when utilizing an environmentally friendly materials has the advantage that can dramatically increase the income by possible organic production. For other crops, it made up a lot of studies on water management, But the studies on water management of ginseng is somewhat lacking. Therefore, this study was conducted to establish appropriate soil- moisture-management-systems within the house of ginseng cultivation. Methods and Results : The type of house is a double steel structure. The first layer was PE film, the second layer was the blue shading net and 75% black shading net. The Soil texture was silt loam and the Soil Series was YEONGOK Series. Install the house on the adjacent paddy soil and upland soil, and planting on April 30, 2011 which was cultivated by the straw mulching. The irrigation start point was the 40, 30, 20kpa, and the end point was treated with 15, 10kpa. Soil moisture measurements were determined by tension meter(Jet Fill) depth 20cm in soil. Growth and Yield Survey was conducted in accordance with the Rural Development Administration (RDA) standard research. Statistical analysis of the results were analyzed using the Microsoft's Excel 2003. Conclusion : In a survey due to differences in soil traits and Irrigation point, from 2 years to 4years of root weight and yield of Ginseng were heavier in the upland, especially 30kpa irrigation point treatment was heaviest than the other treatments. From 5year to 6 Years of ginseng has showed heavier in paddy soil, the most treatment was 30kpa- 15kpa irrigation point. This trend was the same in upland soil. Soil moisture management in the case of silt loam, the humid-state-control was more advantageous than dry-state control in upland and paddy soil.
Background : Acreage of rain-shelter plastic greenhouse to prevent anthrax is being gradually increased according to growing importance of safe Boxthorn production. But When Boxthorn is grown in the hot season in rain-shelter plastic greenhouse, quantity of Boxthorn decreases. therefore the research was carried out to investigate Fertilization mode. Methods and Results : Chungwoon was very strong self-incompatibility. Chengyangjaerae, Chengyang18 and CBP11542-206 was self-compatibility. Artificial fertilization rate was slightly higher in roof and side vents than in side vents of rain-shelter plastic greenhouse in hot season. Pollen sterility due to high temperature is not critical because artificial fertilization rate was high in side vents of rain-shelter plastic greenhouse in hot season. Airborne fertilization rate was significantly lower in all varieties. Open fertilization rate was higher in roof and side vents than in side vents of rain-shelter plastic greenhouse Conclusion : Roof and side vents was good in compared to side vents in rain-shelter plastic greenhouse of Boxthorn because of high Airborne and open fertilization rate. Self-compatibility varieties were better than self-incompatibility varieties in rain- shelter plastic greenhouse because of high open fertilization rate.
