  • It is important to understand the factors that affect the business performance of insect farm for continuous insect farm management. The purpose of this study is to investigate factors influencing the business performance of insect farm. For this study, 1,577 questionnaires were collected through a telephone survey targeting insect farm owner. As a result of analysis using linear multiple regression analysis, the factors affecting total sales were gender, age, business experience, number of workers, and national and local government support projects. The factors affecting the net profit rate were age, business experience, number of workers, national and local government support projects, and education. When the gender of the business operator is male, it only affected the increase in total sales, and it was found that both the total sales amount and the net profit margin increased with the younger the business operator's age.

  • 본 연구에서는 정서곤충을 이용한 치유프로그램 활동이 지역아동센터를 이용하는 아동 43명의 스트레스에 미치는 영향을 조사하였다. 치유프로그램에 이용된 정서곤충은 누에나방[Bombyx mori (Linnaeus)]이다. 스트레스의 정도는 타액 ɑ-아밀라아제 검사를 통해 측정하였다. 스트레스 수치를 평가하기 위한 타액 샘플 채취와 곤충 선호도에 대한 설문지는 곤충치유활동에 참여하기 전과 후에 측정되었고, 활동을 모두 마친 후에는 치유프로그램 참여 경험에 대한 만족도 점수를 평가하였다. 분석 결과, 곤충치유프로그램 활동은 참여 아동의 타액 ɑ-아밀라아제 수치를 통계적으로 낮추고, 곤충에 대한 선호도를 높여준다는 결과를 확인하였다. 누에를 이용한 치유프로그램 활동에 참가한 아동들의 만족도는 5점 만점에 4.23점이었다.

  • The composition of the bacterial populations in Gorosoe(Acer mono Max.) sap was characterized during storage with different heat treatments($63^{\circ}C$ for 30 min and $73^{\circ}C$ for 15 sec). The saps were aseptically collected at 0, 15 and 30 days of storage and analyzed by dilution plating and 16S rDNA PCR-DGGE analysis. There were significant differences in the total number of colony forming units(CFUs) of bacteria between heated and nonheated saps. Bacteria of nonheated sap were present at a level of $3.4{\times}10^7CFU/m{\ell}^{-1}$, whereas living bacteria were not detected in the heated sap. According to the 16S rDNA sequence and DGGE analysis, Pseudomonas sp. was the most abundant bacterial strain in the samlpes, and the bacterial community structures become more simplified with time and were composed of the Chryseobacterium sp. with time. These results allowed us to characterize the dominant bacteria involved in Gorosoe sap and to better understand their dynamics throughout storage.

  • An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ2-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

  • Benthic macroinvertebrates were seasonally sampled from upstream and downstream of the Gunwi Dam construction site from 2006 to 2012. Totally 148 and 165 species were collected at the upstream and downstream sampling sites, respectively. At the upstream area after dam construction, there was no significant change of the numbers of non-insect taxa, but at the downstream area, the non-insect taxon numbers were increased gradually. The individual ratio of Ephemeroptera and Diptera had higher value than the other taxa in both of up and downstream. The trichopteran individual ratios were increased in upstream sites, but decreased in downstream sites from 2010. Also, non-insects and coleopteran individual ratios were decreased in upstream, but increased in downstream after completion of dam construction. The annual range of fluctuation in community indices narrowed after construction. According to a functional feeding group analysis, the individual ratios of FC (Filtering Collector) were increased, and GC (Gathering Collector) and SC (Scraper) were decreased in upstream sites annually. In contrast, the annual individual ratios of FC were decreased, and GC and SC were increased in the downstream sites.

  • Difference of the inset diversity and community structures between the bog Hwaeom-neup and its surrounding forest of Mt. Wonhyo-san located at Yangsan were investigated. Overall 15 orders, 87 families, 204 genera and 233 species were identified. Hydrophilic Harpalidae species were observed in small number at the bog, while the insect species representing hardwood forest were also collected at the bog. Species diversity was relatively higher at the forest (H'=4.80) than at the bog (H'=4.10). The dominant species was Diplous depressus (Gebler) both at bog as well as at forest. Ground-walking Coleoptera as Carabus sternbergi stembergi Roeschke, Damaster jankowskii jankowskii (Oberthur) and D. depressus was spread from forest into bog. Longhorn beetles Leptura arcuata Panzer and Chlorophorus diadema (Motschulsky) being characteristic species of shrub forest were also observed spreading into bog. It was consequently suggested that the bog was in part progressed into dry succession and its boundary was not clearly defined with forest at least upon the structure of insect commnunity.

  • 경남의 대표적 습지인 주남습지를 구성하는 주남저수지, 동판저수지, 산남저수지와 인근의 인공 연꽃단지에서 2010년 5월부터 10월까지 육상 곤충상을 조사하고 군집특성을 분석하였다. 네 곳에서 총 12목 85과 268종, 5,730개체가 조사되었다. 조사된 종 수는 딱정벌레목 63종, 나비목 60종, 노린재목 37종 순이었다. 총 조사된 곤충 수에 대한 목별 개체수의 비율은 딱정벌레목 25.9%, 잠자리목 22.3%, 나비목과 메뚜기목이 각각 15.4%와 12.7% 이었다. 조사 저수지별로는 주남저수지에서 175종, 동판저수지에서 197종, 산남저수지에서 154종이 조사되어 비슷한 양상을 보였으나 인공 연꽃단지에서는 86종이 조사되었다. 조사된 4곳의 곤충상을 요약하면 딱정벌레목에서는 일본잎벌레, 잠자리목에서는 고추잠자리, 나비목에서는 네발나비가 우점종이었다. 조사 전(全) 기간에 대한 종다양성 지수를 분석한 결과, 우점도 지수는 인공 연꽃단지가 0.25로 가장 높았고 주남저수지가 0.08로 가장 낮았다. 다양도 지수는 주남저수지가 4.48, 동판저수지가 4.44, 산남저수지가 4.28, 인공 연꽃단지가 3.87로 모두 높은 편이었다. 각 습지의 곤충상 유사도를 분석한 결과 주남저수지와 동판저수지의 유사도가 0.96으로 가장 높았으며, 세 곳 저수지와 인공 연꽃단지의 유사도는 0.45~0.53으로 낮은 편이었다.
