        다른 장르의 게임에 비해 포커는 게이머의 심리적 요소가 많은 영향을 끼친다. 본 논문에서는 CNN과 SVM을 기반으로 온라인 포커 게임에 게이머와 아바타 간의 감성연결을 실현하기 위한 새로운 감성 인식방법을 제안한다. CNN모델을 이용하여 원래 얼굴 이미지의 특징을 추출하고, 다중 클래스 SVM분류기를 사용하여 목표 이미지를 인식하고 분류한다. FER-2013데이터베이스에서 이 방법은 감성인식률 68.79 %를 달성하였다. 기존의 다른 감성 인식 모델과 비교하면, 이 모델은 뚜렷한 장점을 보일 수 있다. 본 게임은 Socket 통신방식을 통해 감성인식결과를 Seven Poker로 전송하여 아바타가 게이머와 같은 감성을 표현하도록 설계하였다. 온라인 포커 게임에 감성연결 기술을 이용하면 게임과 인간의 상호작용이 향상될 뿐 아니라 게이머가 상대방의 심리적인 활동을 효과적으로 분석할 수 있다. 감성연결 기술은 게임에서 게이머들에게 새로운 게임 경험을 제공할 수 있는 기술이라고 생각된다.

        Background : This experiment was conducted to study the characteristics of Korean ginseng (Panax ginseng C. A. Meyer) growth by LED artificial light source in the plastic house using multi-stage cultivation facility and artificial soil. Methods and Results : Seedlings of Korean ginseng cultivar cultivated from 6:00 am to 6:00 pm by adjusting the ratio of 1 : 1, 2 : 1 and 3 : 1 for red light and blue light for the LED light quality test. Controls were tested by treating the white light (fluorescent lamps) for the same time. The average temperature inside the plastic house remained above 25℃, then below 25℃ after mid-August and below 20℃ after mid-September. The temperature near the roots of the artificial soils was higher than 26℃ in late July and early August and lowered to 20℃ or lower in all treatments in September. The pH of the soil was in the standard range, but the EC value was 2.89 in the soil before the test and 5.83 in the white light treatment, higher than the standard range of 1.0. The light intensities were 95.3 μmol and 94.9 μmol in the 3 : 1 and 2 : 1 ratios of red and blue light, respectively. The photosynthetic rate was 1.72 μmole CO2/㎡/s in 3 : 1 treatment and 1.9 times higher than white light treatment. As the red light ratio increased, the light amount and photosynthetic rate increased. Growth characteristics of aerial parts (plant height, leaf length etc.) by LED irradiation were longer than that of white light treatment in the 2 : 1 or 3 : 1 treatment of red light and blue light. The root length was the longest at 13.7 ㎝ in the 3 : 1 treatment of red and blue light, taproot length were 6.9 ㎝ and 6.6 ㎝ in the 2 : 1 treatment and 3 : 1 treatment, respectively, longer than 4.3 ㎝ in white light. Root fresh weight was the heaviest (3.6 g/plant) in 3 : 1 treatment for red and green lights. Conclusion : It was confirmed that the rate of photosynthesis of Korean ginseng was higher than that of white light treatment and the growth characteristics of aerial and root parts were excellent at the ratio of 3 : 1 of LED red light and blue light in plastic house using multi-stage cultivation facility and artificial soil.

        Background : This study was conducted to investigate the effect of inorganic compounds (germanium etc) on the characteristics of growth and ginsenoside contents in Korean ginseng (Panax ginseng C. A. Meyer) cultivated in plastic houses. Methods and Results : The experiments were performed in the Jinan (elevation: 300 meters above sea level). Seedlings (n = 72 per 3.3㎡) of Korean ginseng cultivar were planted on March 23, 2015. Shading material of plastic house was blue-white vinyl. From May to September of each year, 500 and 1,000 times diluted solution of germanium and silicate and these mixed solutions were drenched once a month. The chemical properties of the soil are as follows : pH, EC, organic content, and P2O5 of the soil were within the proper range, and the Mg content of the Ex-cations was lower than the standard value in 3 treatments, including 500 times solution of silicate. The rate of photosynthesis in Korean ginseng leaves were 2.2 - 2.5 μmole CO2/㎡/s in germanium and silicate treatment than in the non-treatment (1.5 μmole CO2/㎡/s). In the mixed treatment of silicate and germanium, the growth characteristics of the aerial parts (leaf and stem) of the Korean ginseng plants tended to be higher and longer than the other treatments. In a mixed germanium and silicate treatment, the root length was 33.3 ㎝, diameter was 23.5 ㎜, and the weight was the best at 53.8 g. The ginsenoside content was 16.8 ㎎/g in germanium treatment, 16.3 ㎎/g in germanium + silicate treatment. These were 37% and 33% higher than the control, respectively. The incidence of disease such as Alternaria panax was less in the inorganic treatment than in the non-treatment, and the incidence of disease was significantly decreased in the treatment with germanium + silicate. Conclusion : By soil drench of inorganic ingredients in Korean ginseng plastic house cultivation, the growth of the aerial and root parts in ginseng were more improved than non-treatment and ginsenoside content was increased and decreased the incidence of disease.

        Background : The purpose of this study was to establish the optimum organic compost composition and fertilizer application for nutrient management during the cultivation of Korean ginseng (Panax ginseng C. A. Meyer) in the greenhouse. Methods and Results : Wood chips, popped rice hulls, and mixed expeller cake were mixed with certain contents, fermented microorganisms were added, and fermented for about 100 days to produce organic composts. Organic compost was applied to the greenhouse soils at a rate of 1,500 – 3,000 ㎏/10 a, and the Korean ginseng seedlings were planted (2015) and cultivated. The growth and quality characteristics of 4-years-old Korean ginseng were investigated as follows. In all treatments, the emergence date were April 17, and the emergence rate were 70 - 74%. Soil chemical properties such as pH (6.7 - 6.8) and trace element Ca (7.9 - 9.2 cmol+/㎏) were higher than the standard values, and EC, P2O5 and OM were appropriate. Disease incidence rate were less than 0.2% in the control (treatments of livestock manure compost 1,500 ㎏/10 a) and treatment 3 (wood chips 60% + popped rice hulls 40%), but there were no disease in other treatments. Plant growth such as plant height, leaf length, and stem diameter were superior to treatment 1 (wood chips 20% + popped rice hulls 80%), and growth of underground part such as root length were excellent in treatment 1 as a whole. In particular, in the application of 1,500 - 2,000 ㎏ of treatment 1, root weight (39.9 g, 42.3 g/plant, respectively) were superior to the other treatments. In general, as woodchip content and usage amount increase, root weight tended to decrease. Conclusion : It is considered appropriate to apply 1,500 - 2,000 ㎏/10 a of fermented compost of organic material which is mixed with wood chips (20%) and popped rice hulls (80%) with mixed expeller cake when growing Korean ginseng in the plastic house covered with blue-white vinyl.

        Background : This study was conducted to examine the suitability of the blue/white vinyl for ginseng cultivation greenhouses in different regions in an effort to develop a stable ginseng cultivation technology and contribute to popularizing ginseng greenhouse farming. Methods and Results : For comparison purposes, ginseng plants were cultivated in the traditional shading and greenhouse shading facilities. The average temperature in the greenhouse shading facilities during the period of May through October was 20.5℃ in Namwon, 21.4℃ in Jinan, and 23.3℃ in Iksan, with Iksan recording a 1.9–2.8℃ higher average temperature, presumably due to its location in a plain area with low elevation. The average temperatures in the traditional shading facilities ranged between 22.9℃ and 25.7℃, 2.4–2.6℃ higher compared with the greenhouse shading facilities. As for the incidence of disease and pest, as low as 0.1–0.3% of the plants grown under greenhouse shading were infected with Colletotrichum dematium, Alternaria panax, and Rhizoctonia solani, whereas much higher incidences were noted in the control plants, with 3.3–11.3%, 4.7–17.0%, 0.1–0.5%, and 3.0–5.7% infected with Colletotrichum dematium, Alternaria panax, Rhizoctonia solani, and Phytophthora cactorum, respectively, throughout the regions. Heat injury occurred only in Iksan (0.3%) in the case of greenhouse-shaded plants, whereas the control plants suffered from much severer heat injury: 3.5% in Namwon, 10% in Jinan, and as high as 35.3% in Iksan. As for the roots, Namwon outperformed other regions in root length (29.7 ㎝), taproot length (8.7 ㎝), and taproot diameter (25.3 ㎜), and also the root fresh weight (53.4 g), followed by Jinan (48.7 g) and Iksan (40.4 g). In yield as well, the greenhouse in Namwon outperformed other regions with 1,297㎏/10a, followed by Jinan (1,183 ㎏) and Iksan (932 ㎏). The effect of greenhouse blue-white vinyl shading on yield by region was analyzed to increase of 177% in Namwon, 209% in Jinan, and 173% in Iksan with respect to their respective traditional shading facilities. Conclusion : The suitability of the blue/white vinyl shading in ginseng cultivation greenhouses was tested experimentally in three different regions. As a result, greenhouse-shaded ginseng plants were found to be much less affected by heat injury compared with traditionally shaded ginseng plants, resulting in much higher yields in all regions. This allows the conclusion that greenhouse ginseng cultivation can contribute to more stable ginseng yield and popularization of ginseng cultivation.

        Background : This study was conducted to determine the optimal ginseng greenhouse shading material for minimizing heat injury and maximizing the yield of ginseng plants in an effort to develop a stable ginseng cultivation technology and contribute to popularizing ginseng greenhouse farming. Methods and Results : Three different types of greenhouse shading material were used: polyethylene (PE) film + black screen (95%), light scattering film + black screen (75%), and blue-white vinyl. Important experimental details were implemented in accordance with the Analysis Standard of Agricultural Test and Research set out by the Rural Development Administration. The average greenhouse temperature for the period of May through October was 20.0℃ under the PE film + black screen, 20.2℃under the light scattering film + black screen, and 19.7℃ under the blue/white vinyl. High average photosynthesis rates of ginseng plants were demonstrated by light scattering film+black screen (2.35 μmole CO2/㎡/s) and blue-white vinyl (2.38 μmole CO2/㎡/s), with the PE film + black screen showing a considerably lower photosynthesis rate (1.55 μmole CO2/㎡/s). Heat injury occurred in 0.3%, 10%, and 0.1% of the plants grown under the PE film + black screen, light scattering film + black screen, and blue-white vinyl, respectively. As for the roots, the blue-white vinyl outperformed the other shading materials in root length (25.7 ㎝), taproot length (5.9 ㎝), and the number of fine roots (23.2). The blue-hite vinyl also yielded the greatest root fresh weight (30.2 g), followed by the light scattering film + black screen (29.1 g), with the PE + black screen yielding by far inferior average weight (22.0 g). The highest crude saponin content was yielded by the light scattering film+black screen (16.61 ㎎/g), followed by blue-white vinyl (11.36 ㎎/g) and PE + black screen (11.0 ㎎/g). Conclusion : Comparing the effects of three different shading materials on greenhouse-cultivated 3-year-old ginseng plants, the blue/white vinyl outperformed two other shading materials in most of the growth characteristics, whereas the and the light scattering film + black screen yielded the highest ginsenoside content.

        Background : The organic matter content of land clearing or soil brought from an other place is very low, less than 0.5%. However, the organic matter content of natural habitat soil and leader farmhouse soil was two to three times higher than that of general farmhouse soil. As a result, the yield of Gastrodia elata was higher than that of general farmhouse. Therefore, this experiment was carried out to investigate the yield of G. elata according to the application of green manure crops (GMCs). Methods and Results : This experiment was carried out in a soil with organic matter content of 0.5% in rain shelter greenhouse. The kind of GMCs are corn, Sudan grass, sorghum and oats, and the throughputs per 10 a were 2,000 ㎏, 2,200 ㎏, 1,500 ㎏ and 700 ㎏ of each. The soil preparation was carried out after treated of GMCs at least one month before G. elata was formally planted. As the results of these experiment, organic matter content in soils increased 4 - 5 times compared with before treatment. As a result, the yield of G. elata increased by 21 - 41% in all treatments of GMCs. In addition, there was 2 - 5% more G. elata of good merchantable quality. However, the soil temperature in the summer season period of 2016 (7.1 - 8.31) was 1.2 - 1.6℃ higher than the previous year. The day when the outside temperature was above 30℃ was 41 days. It doubled from the previous year. Soil moisture content showed similar tendency according to treatments. As a result, 20 - 30% of high temperature damage and 20 - 50% of putrefaction occurred, and the total yield also decreased by 20 - 30% compared to normal year. Conclusion : In conclusion, some organic matter is needed for cultivation of G. elata. Therefore, it is considered that it would be better to keep the organic matter content at 2 - 3% when the destination are managed, and to use corn or Sudan grass as the GMCs.
