This study contemplates the tendency of the examination questions for History of Korean Landscape Architecture. The study targets the questions of 'Landscape Architecture History' which has been set in the written test for National Qualification Test of a landscape engineer for recent 10 years from 2005 to 2014 and derives analyzable items based on the guidelines of question-setting presented by Human Resources Development Service of Korea. The results of the study are drawn as follows. First, among 5 areas composing Landscape History, the proportion of Korean Landscape questions is getting increased while that of Western ones is decreasing. Second, about 30 traditional trees and 11 types of traditional landscape elements including traditional facilities were shown in Korean Landscape questions. Besides, history, geographic, practical science, horticulture, anthology books and the 25 tradition landscape-related historic documents categorized as the garden painting data were found. And the kings from ancient era to Choseon Dynasty who were associated with the time of palace garden building, the builders or owners of the villas, the authors of the document and Chinese scholars also appeared. Third, there were no the questions of prehistoric times and Balhae Kingdom, whereas those of Choseon Dynasty were dominantly focused. Among the traditional sites of Choseon Dynasty, Byeolseo(villas) were set most, followed by Dosung or Gung-gweol(castle towns or palaces), houses, Nu Jeong Dea(pavilions) and Seowon(local schools) in order. Nak-an eupseong and Yong-ju sa were the only cases for a castle town and a temple each. Fourth, being associated with tradition spaces, the questions asked for understanding the detailed contents of time of sites' construction, builders, location features, building structures, ground plan types and the components s of garden. In addition, as a result of checking whether traditional landscape sites were shown in the set questions in 9 Korean Landscape textbooks, Dongchundang, Pungamjeonsa, Simgogseowon did not appeared. As a result of reviewing the tendency of the examination questions for History of Korean Landscape Architecture, the questions which ask minor facts without generality and which include difficult information and site uncomprehended in the textbook should be reconsidered.

A field experiment was carried out to determine the optimum application level of dicamba herbicide for efficient control of Abutilon avicennae in silage corn field. Five treatments of application levels (0 ; control, $0.75{\ell},\;1.0{\ell},\;1.25{\ell}\;and\;1.5{\ell}$) were arranged at National Livestock Research Institute, RDA, Suwon in 1995 and 1996. The hybrid silage corn was P 3352 and dicamba herbicide was applied at 5~6 leaf stage of corn. The growth of corn was poor in control plot, and the days for tasseling and silking were delayed 2~3 days when compared with the plots of herbicide application. The control efficiency of Abutilon avicennae was excellent as 94.7~98.1% in the plots of dicamba application. A slight injury of herbicide was observed at early stage of corn when applied at $1.0{\ell},\;1.25{\ell}\;and\;1.5{\ell}$ of dicamba per ha. Forage dry matter(DM) yield, length and weight of ear in the plots of dicamba treatments were significantly higher than those of control. The DM yield of control(12,070kg/ha) was only 64.2~66.9% of dicamba treatment plot(18,050~18,795kg/ha). However, there was no yield difference among dicamba application level. The percentage of ear to total DM yield was ranged from 53.4 to 56.8%. The nutritive value(crude protein, ADF, NDF, digestibility and TDN) was very similar among all treatments. From the above results, it is recommended that optimum application level of dicamba herbicide was $0.75{\sim}1.0{\ell}/ha$ for efficient control of Abutilon avicennae and for silage corn production without herbicide injury.

This experiment was carried out to determine harvest date and cultivar effects on growth characteristics, forage yield and quality of spring sown oats at the middle mountain(450m) area at the forage experimental field, Namweon Branch, National Livestock Research Institute. The experiment was arranged in a split plot design with three replication. The main plot consisted of the harvest date(9 June, 18 June). The subplots consisted of different maturities of oat cultivars such as Cayuse, Swan, Foothill, Cashel, Martlock and Winjardie. The results obtained are summarized as follows; A period of 50 days was required to be first headed from seeding with early maturity oats(Swan), but that of 77 days was required with late maturity(Foothill). The dry matter content of early maturity(Swan) oats at 9 June and 18 June were 24.01% and 35.69%, but that of late maturity cultivars(Foothill) were 14.02% and 22.84%. The fresh yield of late maturity(Foothill) oats at 9 June and 18 June were 62,666kg and 59,666kg, but that of early maturity(Cashel) were 54,222kg and 45,493kg(P<0.05). The dry yield of early maturity (Cashel) oats at 9 June was 10,169kg, but that of early maturity (Martlock) was 6,272kg. But no significant difference was found among cultivars at June 18. Crude protein content of oats were decreased from 14.0% to 11.1% as the growing stage progressed, ADF, NDF and CF contents were increased. And in vitro dry matter digestibility was decreased as the harvest date delayed. The present experiment indicated that spring sown oats(Foothill) can be successfully produced as fresh forage by seeding in middle March and harvesting in 10 and 20 June at the middle mountain (450m) area.

Experiment was carried out to determine the agronomic characteristics, forage yield of silage corn(Zea mays L.) soil chemical characterictics and $NO_3-N$ level in infiltration water by different application rates of daily liquid manures. Four treatment consisting of chemical fetilizer, $200kg\;N\;ha^{-1}$, daily liquid manure $200kg\;N\;ha^{-1}$, $300kg\;N\;ha^{-1}$ and $400kg\;N\;ha^{-1}$ were arranged in a randonmized complete block design with three replicates. The results obtained at National Livestock Research Institute, RDA., in Suwon from 1996 to 1997 are summarized as follows; In plant height and crude protein content, it were appeared to highest by 264cm, 6.8% at the cattle slurry 150% plot(T3), respectively. but Dry matter yield(14.5MT/ha) and TDN(9.5MT/ha) production of chemical fertilizer plot(T1) were highest. Among daily liquid manure amount, dry matter yield(14.0MT/ha) and TDN yield(9.1MT/ha) of daily liquid manure 100% plot(T2) were resulted to 96% and 97% of chemical fertilizer plot(T1). End year's soil organic matter and phosphate content were appeared to high than those of beginning year in daily liquid manure plots, but it was not in proportioned to increase according to slurry amount. $NO_3-N$ level in infiltration water lower than 60cm of all plots were lowed than a permitted limit of cattle drinkable. As a result, it was appeared that the optimum application amount of dairy liquid manure was 200kg/ha by manure-N.

In developing soil wetting agent using polyoxyethylene octylphenyl ether [$C_8H_{17}O(C_2H_4O)_{10}H$, POE], the effect of mixtures of POE and polyoxyethylene+polypropyleneoxide tridecylether (1:1, w/w, CM-1), polyoxyethylene+polypropyleneoxide tridecylether+propyleneglycol monomethylether (1:1:2, w/w/w, CM-2) or glycerin+ditridecyl phthalate (1:1, w/w, CM-3) on changes of concentration of POE, initial wetting, evaporative water loss, water infiltration, and changes of physical properties in root media were determined. The mixtures of POE and CM-1, 2, or 3 with zeolite or vermiculite as carrier had high concentrations of POE in root media during 6 elution times, but those after 6 times decreased rapidly indicating unstable elution of POE. The commercial AquaGro was more effective than the mixtures of POE+CM-1, 2, or 3 in water retention during 18 hours. Root media incorporated with POE+CM-2 held more water than any other treatments at 84 hours after watering, but the differences among treatments except control were not significant. In the treatments with zeolite as a carrier, POE+CM-3 had the greatest evaporative water loss followed by POE+CM-2, AquaGro, control, and POE+CM-2. In the treatments with vermiculite as a carrier, POE+CM-1 had the highest evaporative water loss followed by POE+CM-3, AquaGro, control, and POE+CM-2. In the effect of mixtures with zeolite as a carrier on infiltration of water into root media, the treatment of POE+CM-1 had the highest amount of water infiltrated followed by POE+CM-3, AquaGro, POE+CM-2, and control. In the effect of mixtures with vermiculite as a carrier on infiltration of water into root media, the treatment of POE+CM-3 had the highest amount of water infiltrated followed by AquaGro, POE+CM-1, POE+CM-2, and control.

In this Paper, we propose the new face detection and tracking method based on template matching for real-time applications such as, teleconference, telecommunication, front stage of surveillance system using face recognition, and video-phone applications. Since the main purpose of paper is to track a face regardless of various environments, we use template-based face tracking method. To generate robust face templates, we apply wavelet transform to the average face image and extract three types of wavelet template from transformed low-resolution average face. However template matching is generally sensitive to the change of illumination conditions, we apply Min-max normalization with histogram equalization according to the variation of intensity. Tracking method is also applied to reduce the computation time and predict precise face candidate region. Finally, facial components are also detected and from the relative distance of two eyes, we estimate the size of facial ellipse.

This experiment was conducted to compare the agronomic characteristics and productivity in induced vetch cultivars at paddy field of Cheonan (National Institute of Animal Science) and Naju (Jeollanam-Do Agricultural Research and Extension) from 2004 to 2006. The vetch cultivars used in this study were 6 varieties ('VV4712', 'Welta', 'Penn-02', 'Ostsaat', 'Oregon com.', 'Sander 2'). At the Naju region, the most fast flowering date variety was Chinese milk vetch, Sander 2 was very late as 20th May. The average dry matter (DM) content was 21.7%. Vetch cultivars were severely different. 'Oregon com.' showed the highest DM yield by 5,406 kg/ha but the DM yield of 'Ostsaat' was low by 4,852 kg/ha. At the Cheonan region, the most fast flowering date variety was Korean milk vetch, Sander 2 was very late as 25th May. The average dry matter (DM) content was 16.9%. Vetch cultivars were severely different. 'Welta' and 'Ostsaat' showed the highest DM yield by 2,173 kg/ha and 1,883 kg/ha respectively, but the DM yield of 'VV4712' was low by 1,079 kg/ha. Crude protein (CP) content of vetch was 11.5%. 'Sander 2' showed the highest CP content by 14.4% and Chinese milk vetch showed the highest content by 19.3%. Average acid detergent fiber (ADF), neutral detergent fiber (NDF) and total digestible nutrient (TDN) content were 26.8%, 42.2% and 67.5%, respectively. The results of this experiments indicated that the productivity of vetch cultivar varied from winter hardness, therefore we will consider the winter hardness as main factor when induce vetch cultivars. According to the results obtained from this study, it is suggested that 'Oregon com.' at the Naju region and 'Welta' and 'Ostsaat' at the Cheonan region would be recommendable for fall sown 'vetch' for dry matter production.

Forest carbon stocks change due to land use change is an important data required by UNFCCC(United Nations framework convention on climate change). Spatially explicit estimation of forest carbon stocks based on IPCC GPG(intergovernmental panel on climate change good practice guidance) tier 3 gives high reliability. But a current estimation which was aggregated from NFI data doesn't have detail forest carbon stocks by polygon or cell. In order to improve an estimation remote sensing and GIS have been used especially in Europe and North America. We divided research trends in main countries into 4 categories such as remote sensing, GIS, geostatistics and environmental modeling considering spatial heterogeneity. The easiest way to apply is combination NFI data with forest type map based on GIS. Considering especially complicated forest structure of Korea, geostatistics is useful to estimate local variation of forest carbon. In addition, fine scale image is good for verification of forest carbon stocks and determination of CDM site. Related domestic researches are still on initial status and forest carbon stocks are mainly estimated using k-nearest neighbor(k-NN). In order to select suitable method for forest in Korea, an applicability of diverse spatial data and algorithm must be considered. Also the comparison between methods is required.

This study was conducted to develope a new type of ready-to-eat smoked Sebastes schlegeli product with high acceptability and extended shelf-life. A Sebastes schlegeli was salted at 4% salt concentration for 6 hr at $4^{\circ}C$. The cold smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$ followed by smoking for 2 hr at $22{\sim}24^{\circ}C$. The warm smoking conditions for the salted Sebastes schlegeli consisted of drying for 2 hr at $22{\sim}24^{\circ}C$, smoking for 2 hr at $22{\sim}24^{\circ}C$, and smoking again for 30 min at $47{\sim}50^{\circ}C$. The rancidity of the smoked Sebastes schlegeli did not change after 1 year storage at $-20^{\circ}C$ by monitoring the iodine value, peroxide value, and acid value. The number of viable cells in the cold and warm smoked samples were counted as $7.4{\times}10^5$ and $6.2{times}10^5$ CFU/g, respectively. Viable cells were not detected after 1 year of storage at $-20^{\circ}C$. The sensory evaluations of the processed Sebastes schlegeli showed that elastic texture increased with smoking as compared to with salting. There were no significant differences between cold and warm smoking in terms of sweetness, elastic texture, color, and smoke flavor. However, for overall acceptability, preference were in the oder of cold smoked, warm smoked, and salted.
