This study was conducted to evaluate the microbial contamination levels in the processing company of Nuroong-ji. Microbial contamination levels were examined for sanitary indication bacteria such as aerobic plate count, coliforms and fungi, and pathogenic bacteria such as Escherchia coli O157:H7, Salmonella spp., Staphylococcus aureus, and Listeria monocytogenes. Contamination levels were detected differently according to handling materials and purposing work-space. The equipments and raw materials were not seriously contaminated but there were necessary to attend the cross-contamination. A high contamination level was detected at the process where the interference of the employees was relatively higher than the other process. Standardization of the roasting process (120~170℃, about 10 min) could be necessary to control the microbial organism effectively on Nuroong-ji manufacturing process. At small/medium size foodstuff manufacturers, it is the most important to improve the recognition level of individual hygiene but also expand a hygiene facility.

Network analysis for co‐occurrence of pest insects on host crops

도윤호,최문보 한국곤충학회 2019 Entomological Research Vol.49 No.1

In this study, the co‐occurrence patterns of 618 pest insects for 47 host crops, including vegetables, grains, and fruits, were identified. To identify the pest co‐occurrence patterns for various crops, and the interactions among the pest insects and crops, we employed social network analysis methods. We used three traditional centrality measures (degree, closeness, and eigenvector) to determine the relative significance of each crop and pest as a node in the network. Throughout the network analysis, crops and pest nodes were divided into six groups, based on modularity. Crops in the same group could be considered as alternate hosts for pests from the same group. There were clear differences in the cultural practices between groups (i.e., dryland farming versus wetland farming). This indicated that dryland crop pests do not use wetland crops as resources. Pome fruit trees, such as apple and pear, had high centrality indices, which indicated the importance of these crops in the network and their high vulnerability to damage by a multitude of pests. In this study, although it was assumed that all crops were cultivated on the same piece of land during a single growing season, the complex interactions between the whole units were visualized and analyzed as a computable network.

Quantitative analysis of research topics and public concern on V. velutina as invasive species in Asian and European countries

도윤호,김정배,심정희,김창준,권오석,최문보 한국곤충학회 2019 Entomological Research Vol.49 No.10

We analyzed the research topics and public concern on Vespa velutina as an invasive species in Asian and European countries quantitatively though digitized texts such as scientometrics and conservation culturomics.We collected 126 scientific publications of V. velutina published during the last three decades, and 423 news articles on V. velutina in South Korea. In total, 22 countries have contributed to scientific research on V. velutina. Research topics were clearly classified to studies on taxonomy and invasion of V. velutina. In South Korea, people have recognized the ecological and health impact of V. velutina. Although scientific and public interest in V. velutina has increased since 2000, research topics may be narrow and information of news articles may be simple. To achieve the sustainable management of V. velutina, multilateral studies including environmental, social, and economic research on V. velutina are necessary.

울주군 정족산 곤충군의 분류학적 다양성과 생태학적 평가

도윤호,문태영,남상호 대전대학교 기초과학연구소 2002 自然科學 Vol.13 No.1

울산광역시 울주군 웅촌면 정족산에서 산기슭의 마을(고도 50m), 산지중층(정족산. 50~510m) 그리고 무제치 제 1늪과 제2늪(510~545m)으로 구분하여 곤충군의 다양성을 조사한 결과 11目 60科 124屬 143種으로 정리되었다. 관찰된 대부분의 종들이 경작지와 도시화 특징을 보이는 종들이었으며, 마을에서 Pheropsophus javanus (Dejean) 남방폭탄먼지벌레가 우점종으로 나타났으며, 산지중층에서는 Megacopta punctatissima (Montandon) 무당알노린재, 무제치늪에서는 Diplous depresus (Gebler) 사개천먼지벌레가 우점종으로 나타났다. 이 세 지역에서 관찰된 종조성에는 전체적으로는 두드러진 차이를 논하기 어렵지만, 지표보행성 갑충군에서는 서로 독립된 다양성 구조가 확인되었는데, 이는 산기슭의 수전경작지와 늪은 본질적으로 차이가 있고 또한 늪과 주변산지도 역시 차이가 있는 것을 볼 수 있었다. 따라서 산지성 늪의 특성을 설명할 수 있는 생물지표종에 대한 연구를 위해 지표보행성 갑충군의 군집의 구조에 대한 자세한 연구가 이루어져야 할 것이다. It was investigated the insect diversity and community structures from Mt. Jungjoksan located at Ulju-gun. The insects were sampled at the village at the bottom, the mid-slope area and the moors of the mountain to see the difference between the sites with a particular interest of the presence of moor inhabiting insects with a strong potential of indicators. Overall 143 species in 124 genera were identified belonging to 60 families under 11 orders. Most species were the insects appearing along agricultural fields and in urban areas. Out of the species. Pheropsophus jauanus (Dejean) was the dominant one in village field, Megacopta punctatissima (Montandon) in the mid -slope areas and Diplous depressus (Gebler) in moors. The species composition between the investigated sites were difficult to draw any distinct differences, while it was confirmed some patterns of independency between the ground-walking Coleoptera groups at the sites. It is suggested that the potential indicator species for wetlands may be established through the detailed tracing the ground- walking Coleoptera in the moors.

도윤호,김항아,김성보,임란영,김성기,주기재 한국습지학회 2012 한국습지학회지 Vol.14 No.3

습지에 대한 인식 정도는 습지를 보전하고 관리하는데 있어 매우 중요하다. 이러한 인식은 단순히 한 시 대의 사회·경제적인 상황뿐만 아니라 역사, 종교, 문화 등과도 밀접한 관계가 있기 때문에 이를 정확히 이해하기 위해서는 학제적인 접근이 필요하다. 본 연구에서는 역사적으로 습지에 대해 어떻게 이해했는가를 파악하기 위해 조선시대의 사료들을 분석하였다. 조선시대의 사료들에서 습지를 지칭하는 용어를 찾고 습지를 어떻게 이용하고 관리하였는가를 파악하였다. 약 20여 개의 단어가 습지 또는 습한 환경을 지칭하고 있었는데, 대부분의 경우 습 지는 부정적인 장소로 인식하고 있었음을 확인하였다. 일부 농지로 전환이 가능하여 소출을 얻을 수 있는 곳이나 수경재배에 필요한 물을 댈 수 있는 수리시설로 이용이 가능한 곳은 중요시 여겨 특별히 관리한 것으로 보인다. 조선시대에는 습지에 대한 부정적인 인식과 더불어 농업생산을 회복하고 증진하는 국가적인 목표를 위해 많은 습 지가 농경지로 개간되었음을 확인하였다.

Spatial-temporal distribution of carabid beetles in wetlands

도윤호,주기재,조현빈,강지훈 한국생태학회 2012 Journal of Ecology and Environment Vol.35 No.1

In this study, we investigated carabid beetles residing in the wetlands to understand their ecological adaptation and strategy selection associated with restricted resources and habitat limitation. The species richness, abundance, seasonal activity, and spatial distribution of the carabid beetles between the Mujechi Wetlands (wetland sites) and Mt. Jeongjok (mountain sites) have been compared. A total of 1,733 individual beetles from 30 species were collected and classified at the studied sites. The wetland sites were identified as having lower species richness and abundance for carabid beetles when compared with the adjacent mountain sites, whereas these beetles were observed to be dominant in the wetland sites than in the adjacent mountain sites. Calosoma inquisitor cyanescens, Carabus sternbergi sternbergi, and Carabus jankowskii jankowskii species were dominant in both the wetland and mountain sites. These species showed significantly different seasonal activity patterns in the wetland sites relative to the mountain sites. Although the three listed carabid species were observed to be widely distributed throughout the wetland sites, they still showed preference for drier sites,which clearly shows a distinction in their habitats. The results of the spatial-temporal distribution of carabid beetles in the wetland sites reflect their special strategies regarding space and time partitioning for maintaining their population. The distribution patterns of carabid beetles in the wetland sites also showed the desiccation gradient and environmental changes prevalent in wetlands. Ecological surveys, which use carabid beetles in the wetlands, can then be performed when restoring wetlands and for establishing management practices for improving the habitat quality.

Community changes in carabid beetles (Coleoptera: Carabidae) through ecological succession in abandoned paddy fields

도윤호,정광석,Maurice Lineman,김지윤,김항아,주기재 한국생태학회 2011 Journal of Ecology and Environment Vol.34 No.3

Carabid beetle community changes in paddy fields, abandoned paddy fields, and mountains were investigated to understand differences in species diversity and composition of different habitat types in small agricultural landscapes in South Korea. A total of 2,938 individuals from 37 species were identified and classified from the studied habitats. Diversity in the mountains was higher than that in abandoned paddy fields. As the number of years since abandonment increased, the diversity and stability of the carabid beetle community also increased. Abandoned paddy fields in some paddy field areas and adjoining mountainous areas, left with preconditions for management and control, have provided the opportunity to improve the diversity and habitat of small agricultural landscapes. Species composition changed continuously from the paddy fields to the mountains, in accordance with individual species habitat preferences. Abandoned paddy fields in small agricultural landscapes are believed to play an important role as transitional buffer zones between paddy fields and the adjacent mountainous areas.
