  • This experiment was carried out to investigate the effect of several organic fertilizers on the growth and root yield of Achyranthes japonica N. from 1995 to 1996. Four organic fertilizers were applied: rice straw manure (RSM), fermented rice straw manure (FRSM), mixed oil cake manure (MOCM) and mighty soil manure (MSM). Organic matter, available phosphate, $K_2O$, CaO, and MgO of soil increased in all plots with the addition of organic fertilizers, specifically with MOCM application. The highest contents of total nitrogen were 6.16% for MOCM and the available phosphate contents were very high in all of organic fertilizers except MSM. RSM and MSM with C/N ratios of 22.5, 17.7, respectively, were easily decomposed but C/N ratios of FRSM and MOCM, which were considered as irresolvable organic fertilizers, were 40.9 and 8.4, respectively. FRSM and MOCM applications increased emergence rate and improved the growth characters of shoot and root parts of plants compared to those of N - P - K fertilization. The highest dry root yield resulted from FRSM 20% and MOCM 26% treatment. There were significantly positive correlations between the growth characters of shoot, root parts of plants and dry root yield in A. japonica grown under organic fertilizer applications.

  • This experiment was conducted to investigate the effects of planting density on the growth characteristics and root yield of Achyranthes japonica N. from 1995 to 1996. Stem diameter, no. of branch and fresh weight of above-ground parts per plant were reduced by increasing the planting density, but stem length, length and diameter of main root increased at high density, $25{\times}5cm$. The heighest percent of large roots was 71 % at $25{\times}5cm$ planting density. The dry root yield per 10a at $25{\times}5cm$ planting density was 7% higher than 306kg of $20{\times}5cm$ planting density, but root yields were lower in other planting density compared to $25{\times}5cm$ planting density. The root dry weight showed negative correlation with stem diameter, no. of branch and fresh weight of above-ground parts per plant but showed positive correlation with stem length, length and diameter of main root.

  • This experiment was carried out to determine the effects of topping time and fertilizer split application on the growth and root yield of Scutellaria baicalensis G. In case of stem cutting at 25cm above the soil surface early in July and middle in August, plant height was reduced by 37cm compared with nontreatment, but stem diameter, the number of branch per plant and the growth of root increased. Topping treatment twice produced the highest dry root yield (182kg/10a) of all, 15% higher than nontreatment. When nitrogen and potassium were applied by the basal dressing with 60% and by the top dressing early in July and middle in August with 20% in each time, the growth of plant (both top and root) increased. The dry root yield per 10a in top dressing twice was 12% higher than once.

  • This study was conducted to evaluate the effects of potassium and sulfur power levels on the growth, nutrients' uptake at different growing stage and seed yield of peanut plant and changes of soil chamical properties in a sandy peanut cultivated soil of Nak-dong riverside in 1984. 1. The length of main stem, that of branch NO. and NO. of branches per plant were increased by the increased application of potassium and sulfur powdar. Especially sulfur powder treated plot were shown in positive effect with obtained in main root length, NO. of roots and Wt. of noudles formed per plant, roots' weight of peanut plant was much more than top's Wt. at harvesting stage, and so ratio of dry matter Wt. top/root was low. 2. The noudle's Wt. formed was positively significant recognized with dry matter Wt. of peanut plant at harvesting stage and the treatments of potassium were increased 7-20% compared with potassium non-treated plot and sulfur's treatments were increased 4-13% than that of potassium 15kg/10a treatment which was sulfur's non-treated plot in seed yield. 3. Relationship between all nutrients' uptake at flowering stage and seed yield were positively significant recognized, but $P_2O_5$ uptake and N/S ratio showed negative effect at harvesting stage of peanut plant. 4. By the increase of potassium and sulfur powder application, the soil pH at two different stages were almost not differential and the content of K, $P_2O$ and $SO_4$ in soil and $SO_4/P_2O_5$ ratio were increasing tendency.

  • Field experiments were conducted to investigate the yield and paeoniflorin content between healthy peony and blight plot of top part with every year during 3 years at June, July, August, September, separately. Stem length and diameter, No. of stem in the blight plot of peony were decreased in early in blight time compared with those in no blight growth. No. of flower buds per plant was 5.2, 4.6 in 3 year- grown and 4year-grown plots at late June blight compared with 11.5, 16.2 in no blight. No. of axillary flower was also similar to as above. Main root length and root diameter was most decreased in the plot of late June blight compared with healthy peony. No. of root more than 10mm of root diameter was small in order of blight time, namely Late June, July, August and September. The root dry yield of 4 year healthy peony was most high in 1,603kg per 10a, but it was lowed in 1,007kg in the plot lasted blight during 3years at late June. Paeoniflorin content was no different between 3year-grown and 4year-grown, but it was high in late June blight plot increased with the early in blight time.

  • After the revision of the Urban Park Act in 2005, historical parks emerged in Korea to promote the preservation of historical heritage while also offering recreation and education to ordinary citizens. It is now time to examine the characteristics of domestic historical parks by examining their current operational conditions, and seek appropriate institutional improvements. By studying the characteristics of historical parks in various countries, as well as the trends in the designation and development of domestic historical parks, this study attempts to examine the function and role of historical parks, and seeks a direction for future action. Through its literature review, this study also examines the current state of historical parks through cooperation with relevant public officials and experts. The results of the study show that, despite historical resources being concentrated in sites dating to the Joseon Dynasty, they also include heritage pertaining to persons, events, and places. There is also a trend toward increasing the focus on modern heritage. Historical parks show differences across existing cities and new towns, as well as between major cities and provincial cities. Provincial cities showed a recent trend of using historical parks as important resources for strengthening their economics and solidifying their identities. Also, there are many cases where the designated category for a park is changed to a historical park. In such cases, there may be a problem where certain functions of the park run into conflict. Domestic historical parks can be divided into four categories: heritage parks, memorial parks, historical theme parks, and historic parks. Such detailed classification schemes may serve as the strategic foundation for later conservation and usage of historical heritage, as well as a standard for suggesting concrete direction in the operation of historical parks.

  • 우리나라 전력기술 수준의 평가는 전력기술 중장기 발전계획에 대한 기초자료로서 전력인프라의 투자, 연구개발정책의 수립, 예산배분의 기된 데이터로서 활용되고 있지만, 대부분의 기술수준 평가방법이 전문가 설문조사에 의한 정성적 평가에 그치고 있어 산업 현장의 데이터가 반영되는 데는 미흡한 점이 있었다. 된 논문에서는 이러한 단점을 보완하기 위해 전력기술전반의 수준 평가를 전력산업 각 부분의 계량지표를 관간으로 산출하는 방법에 의한 계량적인 기술평가를 시도하였다. 이 정량적 평가결과를 전문가의 정성적 평가결과 및 과학기술부 조사결과와 대비함으로써 그 차이를 논하고 향후 해석적인 기술평가를 위한 발전방향을 제시하였다.

  • 항공기의 비행경로 시각화는 저고도 임무나 지형고도에 대한 위협을 해소하기 위하여 널리 사용되는 시스템이다. 하지만, 시스템을 구성하기 위하여 GPS와 방대한 지리정보를 구축해야하는 제약으로 인하여 게임 등의 저가형 시스템에 사용되기에는 불가능하다. 본 논문에서는 비행경로를 경제적으로 시각화하기 위한 오픈소스 기반의 DMM(Digital Moving Map) 시스템을 제한한다. 먼저 X-Plane에서 UDP를 통하여 비행정보를 전달받아 구글어스에서 시연 및 지형고도 정보를 DMM 시스템에 전달한다. DMM 시스템에서는 비행체의 고도와 현 위치의 지형고도를 매핑하여 ArcGIS의 MapServer를 통해 가져온 지도 정보상에 비행경로를 시각화한다. 시간간격에 다른 지형고도와 비행체의 고도 비교를 위하여 별도의 모니터링 화면을 제공한다. 본 논문의 결과물은 게임 및 연구 등의 목적으로 비행경로를 시각화하는 분야에 경제적인 도구로 사용될 수 있을 것이다.
