도심형 양식시스템을 바이오플락 양식기술과 아쿠아포 닉스 배양대로 구성하여 사육수를 교체하지 않고 메기를(사육조 3.3톤 2개) 양성한 결과 151일의 사육 후 2.8 g의 종묘가 평균 무게 171.3 g (총중량 56.53 kg)과 235.5 g (총 중량 71.1 kg)로 성장하였다. 입식에서 수확까지의 누적 생존율은 65% 보였고, 성장 구간별로 입식에서 1차 성장 후 분조 이전까지 77.7%, 분조 이후 생존율은 수조에 따라 차이를 보여 각각 92.9%와 78.0%로 나타났다. 초기 바이오플 락 사육수가 만들어지는 과정에서 일부 폐사가 발생하였고, 수질이 안정된 이후에는 폐사가 감소하였다. 메기의 혈액분석결과 사육초기 BFT 사육수가 안정화 이전인 4월에 간 손상 지표인 AST의 농도가 유의적으로 높은 값을 보였으며 ALT, triglyceride는 전 사육기간 내에 차이가 없었 다. Glucose, cholesterol, total protein은 7월에 유의적으로 높은 값을 보이고 다른 기간에는 차이가 없었다. 메기 사육수를 이용한 아쿠아포닉스 가동 시 생산된 식물은 상추, 바질, 적근대, 적치커리 등이 원활한 성장을 보여 5개월간 총 148.85 kg의 식물을 수확하였다. 또한 아쿠아포닉스 시스템에서 식물재배에 따른 사육수 내의 질산 제거능력과, 질산이 제거된 사육수는 메기 사육수로 재사용이 가능한 것으로 확인되었다. 결론적으로, 본 연구에서는 도심형 양식시스템으로 물을 교환하지 않고 어류를 양식할 때 사육 수에 축적된 질산을 제거하고 재사용이 가능한가를 아쿠아포닉스 기술을 결합하여 연구하였으며, 양식생물 (메기) 수용량에 따른 적정 식물량을 유지하면 농수산 복합양식이 가능하다는 것을 보여주었다.

Shrimps infected with WSSV (White Spot Syndrome Virus) generally exhibit white spots in their inner space of carapaces as an acute clinical sign. In an effort to identify the correlation between this acute clinical sign and the condition, the index factors (RNA/DNA concentration and ratio, trypsin activity) were analyzed. A total 580 farmed Fenneropenaeus chinensis and 130 Lithopenaeus vannamei were collected from western and southern fifteen outdoor ponds in Korea. The status of the white spot pathology was divided into four stages (stage 0, stage I, stage II, and stage III), in accordance with the clinical signs as to the size and area of white spots. A significant decrease in RNA concentration and RNA/DNA ratio for multi-infected fleshy prawn (WSSV and vibrio sp.) occurred during the stage III (the whole carapace is covered with a white spot). In particular, RNA/DNA ratio was significantly lower as 1.47±0.04 than other groups. A similar trend was also found in the single infection (WSSV), but the decrease was less than the multi-infection. In the species comparison, both species were vulnerable to the multi-infection, but L. vannamei was more sensitive than F. chinensis (ANOVA, p<0.05): A significant decrease in RNA concentration and RNA/DNA ratio was first found in stage II for the former species, while it was found in stage III for the latter species. Trypsin activity was also showed a similar tendency with nucleic acid variation. Multi-infected shrimp showed drastically decrease of trypsin activity. According to the results, clinical signs of the white spot under carapace have an only physiological effect on shrimp if they covered entirely with white spots.

The purpose of this study is to improve practical skill evaluation method of mushroom - trained certified technician's practical skill evaluation which is one of national qualification tests based on national incompetency standards. One of the current National Competency Standards (NCS), mushroom - trained certified technician uses NCS based practical assessment method. In order to improve the current practical evaluation method, we try to improve practical evaluation method based on field customized problem solving ability and improve the practical evaluation method, various evaluation methods should be constructed. On the purpose of identify the diversity and problems of the evaluation method, the experts of the group consultation, the mushroom-related research institute and the related industry collaborated to identify the problems of the actual mushroom - trained certified technician practicum test, This study on the evaluation improvement method was carried out. In this study, the contents of practical test of the current mushroom traits were analyzed and the trends of the latest mushroom industry were widely reflected.

This study is investigated the growth characteristics(number of available stipe, pileus diameter, pileus thickness, stipe length, stipe thickness, object weight, comparison yield ability of 1 cycle) and storage characteristics of ‘Sanjo 701’ (S7) cultivars according to relative humidity. The S7 growth characteristics were investigated by quantifying the growth and the characteristics according to the relative humidity, The storage stability was investigated every 5 days and freshness was measured by ‘Minamide Method’. S7 pileus diameter is The higher the relative humidity was confirmed becomes larger and the more increased relative humidity also increase the comparison yield ability of 1 cycle. However, pileus diameter or stipe length This could not see the big difference in the three treatment groups, the plieus thickness was no significant difference in the treatment of 80% and 95%. The fresh weight of S7 decreased significantly at 80% and 95% relative humidity after 10 days of storage, but decreased continuity in 65% humiditiry. The elongation percentage of S7 pileus was observe in 95% relative humidity, values of L, a and b (SCI), showed the highest L value in 65% and the a value in 95%. b values were similar in 65%, 80% and 95% treatments. On the ‘Minamide Method’ measure freshness was changed from the 10th day of storage at relative humidity of 95%, but humidity of 65% and 80% treatments, it changed after 15 days of storage. In this study growth characteristics and yield were increased at higher relative humidity, but storage stability was decreased. Therefore, it is deemed necessary to change the relative humidity to produce high quality mushrooms.

본 연구에서는 표준강수지수를 이용하여 가뭄사상을 정의하고, 가뭄심도와 부족 강수량을 대상으로 이변량 가뭄빈도해석을 수행하였다. 부족강 수량은 표준강수지수의 가뭄기준인 -1에 해당하는 강수량을 기준으로 산정하였다. 지금까지 연구에서 가뭄지수의 심도와 지속기간 이용한 빈도해석을 통한 가뭄의 평가가 주를 이루었다. 하지만 이 두 변량은 선형적인 관계가 매우 높아 각 변량에 대한 단변량 빈도해석과 비교하여 정보의 확장성은 크지 않다. 2015년 가뭄의 경우, 서울, 양평, 충주지점의 ‘가뭄심도-부족 강수량’량의 재현기간은 모두 300년 이상의 극심한 가뭄을 나타내고 있지만, ‘가뭄심도-지속기간’에서는 재현기간을 약 10년, 50년, 50년으로 평가하여 큰 차이를 나타냈다. 우기를 포함한 가뭄은 강수량 부족이 심각할지라도 가뭄심도는 가뭄을 상대적으로 낮게 평가할 수 있어 실제 가뭄의 심각성을 나타내는데 한계가 있었다. ‘가뭄심도-부족 강수량’ 빈도해석 결과는 강수량의 절대적인 부족량 정보를 함께 포함하고 있어, 가뭄에 대응하기 위한 지표로 활용성이 높을 것으로 판단된다.
