본고는 단국대학교 부설 한문교육연구소에서 개발 중인 특수 어휘 매칭 툴을 구동시켜 어휘 데이터의 문제점과 개선 방향을 논의하기 위해 작성되었다. 한문교육연구소 개발 어휘 매칭 툴은 최종적으로 한문 고전 텍스트를 토크나이징(Tokenizing) 하기 위한 것이며, 특수 어휘의 매칭은 전체 텍스트를 토크나이징을 하기 위한 첫 단계라고 할 수 있다. 이 어휘 매칭 툴 실행 결과를 MARKUS 자동 마크업과 비교함으로써 매칭 툴과 그 데이터의 장단점을 분석하고, 이 과정에 발견된 문제점에 대해 보완할 수 있는 방향을 제시하였다. 한문교육연구소 어휘 매칭 툴은 한문고전에 특화된 도구로서 중요한 역할을 할 수 있으며, 앞으로 한문 고전의 토크나이징 에도 기여할 것으로 기대된다. 하지만 현재 상태에서는 여러 가지 보완이 필요하다. 우선, 한국 고유의 지명과 인명 데이터를 추가할 필요가 있다. 현재 데이터는 주로 중국의 어휘에 집중되어 있어 한국 고유 어휘가 부족한 상황이다. 추가 어휘데이터를 구축함으로써 해결할 수 있을 것으 로 보인다. 또 별칭의 매칭 문제 등을 해결할 필요가 있다.

This study was conducted to obtain basic data on domestic wild Lanopila nipponica K specimens collected in Jeollanam-do from 2015 to 2017 to investigate the characteristics of fruit bodies and analyze their nutritional components. L. nipponica K. was mainly found near hills, such as in persimmon fields around hills, on mountain trails, and in bamboo fields. L. nipponica K. occurred from July to mid-October, especially after the rainy season or a typhoon, when the air humidity was increased. Rainfall occurred for 8–15 days during the 20 days before the collection date, and the average temperature was ≥ 23oC. The size of the fruit body was 12.3–28 cm, and the weight varied depending on the size; however, the fruit body was estimated to grow overnight, reaching the size observed at its discovery. As aging progressed, the surface of the fruit body cracked, and it turned dark after 6 days. Spores were lump-shaped when the surface was cut with a knife. When the soil on the surface of the site where the fruit body was located was scratched, a white thread-shaped mycelium expanded. At the time of collection, the flesh of the fruit body was white, but it turned brown and fluffy as maturity progressed. On the sixth day after the mushroom was generated, it produced a pungent odor and became friable, resembling a black cotton ball. The surface of the fruit body was white and had a circular or elliptical shape. Crude protein content tended to be high at 59% of the dry weight. The antioxidant activity, determined using the DPPH radical scavenging analysis method, was 167 vitamin C equivalents/100 g. The spores were brown, approximately 6 μm in size, with protrusions on their surface.

팽이버섯 생육용 톱밥배지 내 질소함량(1.2~1.8%)과 생육단계 중 억제기 온도(2, 4, 6 ̊C)에 따른 자실체 특성과 저장기간별 저장 특성을 조사하였다. 톱밥배지의 이화학성 분석 결과 배지 내 질소함량에 따른 pH, 탄소함량 등은 차이를 보이지 않았다. 자실체 생육 특성은 배지내 질소함량이 높아질수록 수량은 증가하는 경향을 보였다. 억제기온도의 경우 질소함량에 따라 자실체 생육에 미치는 경향이 달랐는데 질소함량이 1.28%로 낮은 T1의 경우 억 제기온도에 따른 자실체생육에 차이가 없었고 질소함량 1.5% 이상 배지에서는 억제기 온도가 낮을수록 수량과 갓, 대의 길이가 증가하는 것으로 나타났다. 저장기간에 따른 중량감소율은 배지 내 질소함량에 따른 변화는 관찰되지 않았고, 억제기 온도 4 ̊C이하에서 1.50~1.93%로 6 ̊C보다 낮은 중량감소율을 보였다. 자실체 갓 색도는 저장 31일 후 배지 내 질소함량이 높은 T3에 억제기 온도 4 ̊C처리 에서 L값 84.81, ΔE값이 6.3으로 다른 처리구에 비해 갈변도가 적은 것으로 나타났고 관능평가 또한 저장 31일 후에도 5.2점을 받아 판매 가능한 수준의 품질을 유지하였다. 하지만, 전체적인 결과를 봤을 때 배지 내 질소함량과 억제기 온도에 따른 상관관계는 나타나지 않았으며, 두 조건이 복합적으로 팽이버섯의 품질과 저장성에 영향을 끼치는 것으로 보인다. 따라서, 톱밥배지 내 질소함량 및 생육단계별 온·습도 조건에 따른 팽이버섯의 생육과 저장성 특성에 관한 추가적인 연구가 필요할 것으로 판단된다.

Auricularia polytricha has strong decomposition ability on wood fiber and a wide range of temperature adaptation as mid-high temperature mushroom. In addition, Auricularia polytricha does not require light in the mycelial growth period, but it is cultivated in the field because the light promotes the differentiation of fruiting bodies and affects the pigment formation. This study was conducted to investigate the possibility of the cultivation of Auricularia polytricha (Mont.) Sacc. "Geoni" which was bred at Jeonnam Agricultural Research Institute in 2012 at a simple-typed PE film mushroom house, and to compare the quality characteristics of the Auricularia polytricha (Mont.) Sacc. "Geoni" cultivated at air-conditioned mushroom house. Auricularia polytricha (Mont.) Sacc. "Geoni" was cultivated with sawdust-based media (0.9 kg) every 3 days from June 15 to July 13 at air-conditioned mushroom house and PE film mushroom house, and harvested until July 26th. The temperature and the humidity of the air-conditioned mushroom house was maintained at 23°C and 90-9 %. The Irrigation was conducted 1 time per day and 2 to 3 times per day at air-conditioned mushroom house and PE film mushroom house respectively. The harvesting period were the same for each treatment. The fruiting body was 6.0 ㎝ and 5.1 ㎝ in major axis and 4.6 ㎝ and 4.0 ㎝ in minor axis at PE film mushroom house and air-conditioned mushroom house respectively, as a result the size of the fruiting body grown at PE film mushroom house tended to be larger. The thickness of fruiting body was 0.85㎜ and 1.24㎜ at PE film mushroom house and air-conditioned mushroom house respectively. These results are considered to be due to the difference in the humidity control conditions between each treatment. The number of fruiting bodies per bag was 4.3 at PE film mushroom house and more tendency than 3.7 at air-conditioned mushroom house. The springiness of the fruiting body was 1.23 ± 0.21 and 1.01 ± 0.17. the chewiness was 620 ± 89 and 507 ± 128, and the resilience was 0.49 ± 0.03 and 0.35 ± 0.07 at PE film mushroom house and air-conditioned mushroom house respectively. As a whole, it was judged that the physical properties of the fruiting body grown at PE film mushroom house were excellent. Also, when comparing the chromaticity of fruiting body, L(lightness)-a(red color)-b(yellow color) value was 30-5.5-3.9 and 39-6.5-7.5 at PE film mushroom house and air-conditioned mushroom house respectively. The yields did not show differentiated tendency by cultivation time. However, the weight of fruiting body per bag was 308g and 252g at PE film mushroom house and air-conditioned mushroom house respectively. Therefore, according to these result, Auricularia polytricha (Mont.) Sacc. "Geoni" was judged to be a suitable cultivar at PE film mushroom house for summer.

A. auricular-judae cultivars, ‘Yong-a’ was cultivated in JARES on 2015. Ear mushroom have been consumed the form of dried mushrooms imported from china, but the production and consumption of domestic ear mushroom have been increasing recently. However, how the different drying methods affect the quality of domestic varieties is not clear. Therefore, we examined the effects of drying methods to improve the competitiveness of dried ear mushrooms using domestic cultivar, ‘Yong-a’. Ear mushroom samples were dried using sun-drying and hot air drying(50, 60°C) and combined of two methods(hot air drying at 50, 60°C after 3,6 and 9 hours sun drying) and drying time, rehydration ratio, color and hardness, vitamin D2 contents were evaluated. Drying time was the fastest at 60°C hot air drying(11.5h) and the slowest at 50°C hot air drying(16h) and drying time was shorter as the sun drying time was longer. The rehydration ratio was the highest at 60°C hot air drying(18.6%) and increased as the drying time decreased. After drying and rehydration, the color showed no significant difference between drying methods. The hardness of rehydrated mushroom was highest at sun drying and 60°C hot air drying. The contents of ergosterol were not significantly different by drying methods. However, vitamin D2 was lowest at 50 °C and 60°C hot air drying (4.22mg%, 3.87mg%) and highest at sun drying and 50°C hot air drying after 6 hours sun drying (12.52mg%, 12.99mg%). vitamin D2 contents was higher at 50°C hot air drying than 60°C. According to the results of color, hardness, vitamin D2 contents of dried ear mushroom, sun drying is the best method. When the sun drying is not possible, hot air drying at 60°C is suitable, but it is better to use sun drying method to increase the vitamin D2 contents.

Mineral carbonation using alkali industrial waste is an eco-friendly, economic technology used not only to reuse waste but also to store carbon dioxide. Alkali waste such as slag, cement waste, and coal ash has been mainly used as a raw material required for the technology. Many studies have been conducted to find optimal conditions for Ca/Mg extraction and carbonation with various extraction solvents under different temperatures, pressures of carbon dioxide, ratios of liquid to solid, and reaction times. Furthermore, in order to secure economic feasibility, there have been recent attempts to proceed the mineral carbonation at the room temperature and atmospheric pressure, to recover highly pure carbonate salts, and to reuse the extraction solvent. We expect that future researches will be in quest of economically storing as much carbon dioxide as possible by developing raw materials and carbonation technologies which provide high carbonation efficiency. In this article, we have reviewed recently published domestic and international research papers and then classified them according to the kind of industrial waste and the carbonation technology (direct and indirect carbonations).

Carbon dioxide has steadily increased in atmosphere since the industrial revolution, and it is the main cause of the global warming. In this study, carbon dioxide is stored in the form of insoluble calcium carbonate through indirect carbonation using paper sludge ash (PSA) as a raw material and acids (acetic acid and hydrochloric acid) as solvents. Acid is very efficient to extract calcium from PSA, which is as high as 55%. However, since the pH of calcium extractant obtained using acid is as low as 6 and carbon dioxide is not present in the form of CO32- at the low pH, carbonation reaction does not occur to form calcium carbonate. Sodium hydroxide, therefore, is added into the calcium extractant to increase pH up to 13. The amount of sodium hydroxide is calculated based on the equivalent of calcium in the extractant. Then, carbon dioxide is injected into the calcium extractant for 30 minutes at a flow rate of 0.05 L/min. The calcium extractant is prepared in advance using 40 g of PSA and 1L of 0.7 M acid, and 35mL of 50% sodium hydroxide is added into the extractant to adjust pH. During carbonation, liquid samples are taken at designated intervals to measure pH and calcium concentration. After the carbonation is completed, white solids are collected to dry at 105℃ for 12 hours, which weigh 30.0 g and 33.1 g from the extractants using acetic acid and hydrochloric acid, respectively. The white solids are found to be highly pure calcite by XRD analysis. Based on the solid mass, the amounts of carbon dioxide sequestrated in PSA are calculated to be 330.4 kg CO2/ton PSA and 363.7 kg CO2/ton PSA using acetic acid and hydrochloric acid as solvents, respectively.
