        한국의 과채류 재배 스마트 온실 실태: 온실 환경 및 병해충 관리

        박영균,백성훈,임재성,김민중,이준호,Park, Young-gyun,Baek, Sunghoon,Im, Jae Seong,Kim, Min-Jung,Lee, Joon-Ho 한국응용곤충학회 2020 한국응용곤충학회지 Vol.59 No.1

        스마트 온실은 주로 파프리카, 토마토, 딸기와 같은 과채류 작물을 대상으로 보급되었다. 스마트 온실의 보급량은 지속적으로 증가하고 있지만, 그 실태에 대한 조사는 부족하다. 그러므로, 이번 연구를 통해 한국의 스마트 온실의 시설 규모, 재배작물, 재배방법, 발생 병해충과 실사용자의 평가를 중심으로 한 현 실태를 파악하고자 하였다. 스마트 온실의 리스트는 각 권역별 현장지원센터로부터 제공받았으며, 모든 조사는 농가를 직접 방문하여 수행되었다. 조사된 스마트 온실 농가의 약 50%가 3,300 ㎡~6,600 ㎡ 사이의 규모로 운영하고 있었다. 조사된 농가 중 97.1%가 화학적 방법을 이용해 병해충을 방제하고 있었다. 조사된 농가에서 응답한 주요 식물병은 흰가루병과 잿빛곰팡이병으로 각각 54.4%, 33.8% 비율로 주로 문제가 되는 식물병이라고 응답하였다. 모든 토마토 농가에서 가루이류가 가장 문제가 되는 해충이라고 응답하였다. 그러나, 파프리카 농가의 76.5%, 70.6%가 총채벌레류와 진딧물류를 가장 문제가 된다고 응답하였다. 스마트 온실에 대한 사용자의 만족도는 10점 만점에 평균 7.5점이었다. 이 결과는 한국의 현재 스마트 온실을 관리하고 미래 스마트 온실을 설계하는 계획을 세우는 데 도움이 될 것이라 생각된다. Smart greenhouses are primarily used for growing fruits and vegetables, such as sweet peppers, tomatoes, strawberries. Although the number of smart greenhouses has been increasing exponentially, no studies have been performed to evaluate the state of smart greenhouses in Korea. Therefore, this study was conducted to determine current state of smart greenhouses with regard to greenhouse specifications, crop growing methods, pests, and user satisfaction in Korea. Contact information for smart greenhouses was provided by the officials of local agricultural research and extension services. This survey was conducted by visiting each greenhouse. Results showed that approximately 50% of surveyed smart greenhouses were between 3,300 ㎡ and 6,600 ㎡. The most frequently chosen method for pest control was chemical pesticides (97.1%). Powdery mildew and gray mold comprised 54.4% and 33.8% of the crop diseases, respectively. All tomato greenhouse farmers considered whiteflies the most problematic pest. In contrast, 76.5% and 70.6% of sweet pepper farmers believed thrips and aphids posed significant threats, respectively. The mean satisfaction score was 7.5 out of 10 points, with 10 being "extremely satisfied". These results will aid in decision making with respect to the management of current smart greenhouses and the design of future smart farms in Korea.

        생태통로 내부 식생구조에 대한 지표성 딱정벌레류(딱정벌레목: 딱정벌레과)의 반응

        정종국 ( Jong Kook Jung ),박유정 ( Yu Jeong Park ),이선경 ( Sun Kyung Lee ),이효석 ( Hyo Seok Lee ),박영균 ( Young Gyun Park ),이준호 ( Joon Ho Lee ),최태영 ( Tae Young Choi ),우동걸 ( Dong Gul Woo ) 한국환경생태학회 2016 한국환경생태학회지 Vol.30 No.2

        최근 서식처 파편화에 의한 생물다양성 감소를 막고 서식처간 연결성을 증진시키기 위해 건설되는 생태통로의수가 증가하고 있지만, 생태통로 내부의 식재 및 식생 유지·관리에 대한 구체적인 가이드라인과 내부 식생 구조 차이에 따른 생물 이동 영향에 대한 정보는 부족한 실정이다. 따라서 본 연구에서는 지표성 딱정벌레류를 이용하여 동일한 농업-산림 경관에서 육교형 생태통로 상부 식생이 나지 및 초본으로 이루어진 생태통로(나지/초본형)와 관목림이우거진 생태통로(관목형)에 대한 비교 연구를 수행하였다. 이를 위해 2015년 4월 하순부터 9월 초순까지 생태통로 및 인접한 산림을 따라 함정트랩을 설치하여 33종 4,207개체의 지표성 딱정벌레류를 채집하였다. 지표성 딱정벌레류의 우점종과 지점별 개체수 및 종수는 생태통로 내부의 식생이 복잡한 관목형이 나지/초본형에 비해 더 높은 경향이었으며, 종 구성은 나지/초본형 생태통로의 종 구성은 인근 산림 지역 및 관목형 생태통로에 비해 다른 특징을 보였다. 이와유사하게 생태통로 내부의 식생 관리 여부는 토양습도와 교목층 울폐도에 영향을 주었고, pH, 초본층 피도 및 교목층울폐도는 함정트랩이 설치된 위치에 따라서도 유의미한 차이를 보였다. 결론적으로 생태통로 내부의 식생이 복잡해지면 산림에 서식하는 지표성 딱정벌레류의 산림 패치간 이동 역시 증가할 것으로 판단된다. 따라서 생태통로의 생태적기능을 향상시키기 위해서는 통로 가장자리에는 관목 또는 교목을 식재하여 은신처 및 이동통로로 제공하고, 중앙부에는 대형 포유동물이 이동하기 용이한 나지 형태의 통로를 제공하는 형태로 개선될 필요가 있을 것이다. Korea has put in significant efforts to increase the number of wildlife crossings between fragmented habitats to prevent loss of biodiversity and to encourage the habitat connectivity in Korea. However, there is a lack of biological data on the effect of vegetation structure in these wildlife crossings and guidelines for design and management of wildlife crossing structures in Korea. Therefore, we selected ground beetle assemblages as model organisms to compare the effect of vegetation structure in wildlife crossings, i.e. bare ground- and shrub-type corridors, in agro-forested landscapes. For this study, 4,207 ground beetles belonging to 33 species were collected through pitfall trapping along the northern forest.corridor.southern forest transects from late April to early September in 2015. Dominant species, abundance, and species richness of ground beetles were significantly higher in the shrub-type corridors than the bare ground-type corridors. Also, the species composition of bare ground-type corridor was significantly different compared to the other habitats such as shrub-type corridor and forests. Similarly, environmental variables were also influenced by vegetation management regimes or trap locations. Collectively, our study clearly indicates that the movement of forest associated ground beetles between forest patches can increase as the vegetation in wildlife crossings becomes complex. Although further studies are needed to verify this, there are indications that the current wildlife crossings that comply with the guidelines may be unfriendly to the movement of ground dwelling arthropods as well as ground beetles. To enhance the ecological function of wildlife crossings, the guidelines need to be rectified as follows: 1) Shrubs or trees should be planted along the corridor verges to provide refuge or movement paths for small mammals and ground dwelling arthropods, and 2) Open spaces should be provided in the middle of the corridors to be used as a path for the movement of large mammals.

        We investigated the characteristics of the marine environment and phytoplankton community of surface in the adjoining sea of Yangtze river of the East China Sea in June 2005. According to the analysis of a T-S diagram, three characteristic of water masses were identified. We classified them into the mixed water mass by the Chinese continental coastal waters and Taiwan/Tsushima warm current, Chinese continental coastal waters and Taiwan/Tsushima warm current. The first water mass was characterized by high water temperature, low salinity, low density and very high Chl-a concentration. The second one was characterized by high water temperature, low salinity, low density and high Chl-a concentration and the last one was characterized by low water temperature, high salinity, high density and low Chl-a concentration. The phytoplankton community identified a total of 95 species belonging to 43 genera. The dominant species was 3 species, that is, mainly centric diatom, Skeletonema costatum in the Chinese continental coastal waters. The others one, one dinoflagellates, Prororcentrum donghaiense and one silicoflagellates, Dictyocha speculum var. otonaria in warm current regions. Standing crops of phytoplankton and Chl-a concentration were very high with ranged from 5.9 x 103 cells/L to 1.1 x 106 cells/L, and 2.90 ㎍/L to 26.40 ㎍/L, respectively. Phytoplankton productivity in the East China Sea was controlled by the discharge of Yangtze river waters which include a high concentrations of nutrients.

        Sudden hearing loss(SHL) is defined as an abrupt onset of sensorineural hearing loss which develops over a period of hours or a few days without definitive cause. However, the etiology, treatment and prognosis of the sudden hearing loss are controversial at present time. Authors observed 33 cases(30 patients) with SHL who had been admitted and treated in our ENT department from January. 1992 to December, 1996.. They were evaluated by clinical and statistical analysis. The results were as follows : 1. Of the 33 cases, 8 cases(24.3%) had complete recovery, 6 cases(18.2%) had partial recovery, 3 cases(9.0%) had slight recovery and 16 cases(48.5%) had no response. 2. Those patients who were treated within 2 weeks from onset had better improvement(p<0.01). 3. Those patients who had ascending or flat audiogram pattern had better improvcment(p<0.05). 4. The patients with tinnitus had better improvement than those with vertigo(p<0.001).

      • 중이 진주종에서 랑게르한스 세포 및 림프구의 분포에 관한 면역 조직학적 연구

        박영균,김성현,이준환,최봉남,이도용,도남용,김용기 朝鮮大學校 附設 醫學硏究所 1997 The Medical Journal of Chosun University Vol.22 No.2

        The clinical significance of the middle ear cholesteatoma lies in its association with progressive bone destruction which requires major middle ear surgery for eradication of the pathological lesion. The exact pathogenesis of this disease is still to some extent unknown. Recent advances in immunology have opened a new approach to investigating the etiology and pathogenesis of cholesteatoma by the immunohistochemical technique. The aim of this study was to measure the number of Langerhans' cells and T lymphocytes in the middle ear cholesteatoma through the immunohistochemical technique and to compare them with those in retroauricular skin. The authors used an immunohistochemical method to verify the distribution of the Langerhans' cell in choesteatomatous tissues and the existence of other immunologically active T lymphocytes, using ABC technique for cholesteatomatous tissue and retroauricular skin. The results showed that active immunological processes including the recruitment of Langerhans' cell were present in the cholesteatomatous tissue and the Langerhans' cells in choesteatoma increased compared to those in the retroauricular skin. It was also suggested that Langerhans's cell and lymphocytes should play important roles in maintaining chronic inflammatory reaction in the natural course of cholesteatoma and the process of bone destruction.

      • 비·부비동 종양의 신생혈관 형성에서 COX-2 및 VEGF의 역할

        도남용,박성용,조성일,윤혁수,박선홍,박영균,권대승,임성철 조선대학교 2003 The Medical Journal of Chosun University Vol.28 No.1

        Background and Objectives : COX-2, the inducible form of cyclooxygenase(COX), is upregulated in transformed cells and in malignant cells, which have important roles in promotion of colorectal carcinogenesis, invasiveness and angiogenesis. Vascular endothelial growth factor(VEGF) may act as endothelial cell mitogen in various cancer tissues. It will increase tumor growth and angiogenesis. Aims of this study were to asses COX-2/VEGF expression and it's clinical correlation in sinonasal tumors and to investigate the effects on angiogenesis also. Materials and Method : The study samples were obtained from surgical removal of 27 cases of inverted papilloma(IPs), 5 cases of IP with malignant transformation(IP-MT), 16 cases of Squamous cell carcinoma(SCC) in sinonasal cavity COX-2 and VEGF expressions were assessed by immunohistochemical staining. Synchronism of COX-2/VEGF expression in one tumor cell was demonstrated with double immunofluorescence technique. Results : The expression rates of COX-2 were 37% in IP, 80% in IP-MT and 100% in SCC. The positive rates of VEGF were 29 6% in IP, 100% in IP-MT and SCC. COX-2 and VEGF expressions were increased as tumor progressed, and there is a positive correlation between COX-2 &EGF expressions. All clinical features which were compared are not associated with COX-2 &EGF expressions except malignant change in IP(p=0 028). Synchronism of COX-2/VEGF expressions was noted in all positive immunostaining samples. Conclusion : These findings suggest the role of COX-2 pathway could be involved in sinonasal tumor angiogenesis, which is modulated by VEGF COX-2 may act as autocrine factor in VEGF expression. There is a potential role for selective COX-2 inhibitors in the treatment of these lesions.
