The main factor of biodiversity decline in major biological populations around the world is invasion of alien species. To protect native species, it is necessary to manage alien species. Recently, to eradicate ecosystem disturbance caused by alien species in Korea, many efforts have been made to capture individuals using nets and purchase captured individuals. However, there is no standard for classifying species due to the form of nest site or external characteristics of eggs of freshwater turtles. Thus, Mauremys reevesii eggs might be discarded due to mistaking as eggs of alien turtles. Based on more data, this study aims to compare and analyze external differences among eggs of Trachemys scripta elegans, Pseudemys concinna, and M. reevesii and use them as reference materials in the process of eradicating alien turtles. This study measured characteristics of eggs of the three turtle species. As a result of comparison, all variables of external characteristics of alien turtles and M. reevesii eggs showed significant differences. The shape of egg was also different, with eggs of T. scripta elegans and P. concinna showing a bicone shape and those of M. reevesii showing an ellipsoid shape. In conclusion, based on results of previous studies and the present study, eggs of M. reevesii, T. scripta elegans, and P. concinna are different in shape and structure. Thus, it is possible to distinguish between M. reevesii and invasive alien turtle using their eggs.

국내 과학관 수는 지난 10여년 동안 양적으로는 팽창하고 있으나, 대부분이 중소규모의 과학관으로 인력부족 및 과학전시 컨텐츠 부족에 따라 운영에 어려움을 겪고 있다. 이에 따라 과학관이 보유하고 있는 전시 컨텐츠의 DB구축 및 정보 공유를 통해 과학관간 상호 교환 및 교류를 촉진할 수 있는 과학관 전시 플랫폼 구축이 요구되고 있는 실정이다. 국외 선진 과학관의 경우 자연사 컨텐츠의 전산화 및 DB 구축을 통해 대국민 검색서비스를 제공하여 전시품 등을 다양하게 활용하고 있는 추세이다. 따라서 본 연구에서는 과학관에서 활용가능한 자연사 컨텐츠 중, 곤충을 중심으로 이들의 전시 컨텐츠 발굴 및 DB확보 현황과 향후 플랫폼 구축 계획에 대해 소개하고자 한다.

This study was performed to investigate latent problems of Hazard Analysis Critical Control Point (HACCP) prerequisite program operation at Korean slaughterhouses. We analyzed the slaughterhouses HACCP operation assessment reports implemented by Consumers Union of Korea during 2007 through 2008, and also reviewed the livestock products HACCP instruction manual published by Korea National Veterinary Research and Quarantine Service. Non-compliance rates were 14.2% of facility management and 10.9% of sanitary management at mammal slaughterhouses, and 7.4% of facility management and 6.7% of sanitary management at poultry slaughterhouses. A big obstacle to better HACCP operation was a repeated non-compliances identified at the same slaughterhouse. Twenty-six inspection items of the facility management, which were same items used for the business permission standard, is required to be amended to a safety control purpose. Sanitary management items also should be complemented to more precise contents for practical and objective evaluation.

The toxicity of red pine needle hydrodistillate (RPN-HD), 19 RPN-HD constituents and 12 structurally related compounds and control efficacy of four experimental spray formulations containing RPN-HD (0.5. 1, 2 and 3% sprays) to adult Dermatophagoides farinae was evaluated. RPN-HD (24 h LC50,68.33 μg cm–2) was toxic. Menthol was the most toxic compound (12.69 μg cm–2) and the toxicity of this compound and benzyl benzoate did not differ significantly from each other. High toxicity was also produced by α-terpineol, bornyl acetate, geranyl acetate, thymol, linalyl acetate, terpinyl acetate, citral, linalool and camphor (18.79–36.51 μg cm–2). These compounds were more toxic than either deet or dibutyl phthalate. In vapour-phase mortality tests, these compounds were consistently more toxic in closed versus open containers, indicating that their mode of delivery was largely a result of vapour action. RPN-HD 3% experimental spray provided 95% mortality against adult D. farinae, whereas permethrin (cis:trans,25:75)2.5gL–1 spray treatment resulted in 0% mortality. In the light of global efforts to reduce the level of highly toxic synthetic acaricides in indoor environments, RPN-HD and the compounds described merit further study as potential biocides for the control of Dermatophagoides populations as fumigants with contact action.

목 적: 안경구매자의 구매결정요인과 브랜드 자산인식이 구매만족과 구전의도에 미치는 영향에 대한 상호 관계를 알아보고자 하였다. 방 법 : 2011년 10월부터 12월까지 광주지역, 대구지역, 대전지역의 안경원 구매고객을 대상으로 437부의 설문지가 자료분석에 사용되었다. SPSS 18.0 통계 프로그램을 이용하여 구매결정요인에 대한 상관관계분석 과 구매만족과 구전의도에 대해여 다중회귀분석을 실시하였다. 결 과 : 구매결정요인은 고객서비스 및 디자인요인, 상품특성요인, 구매경험요인, 컨텐츠 및 커뮤니티요인 순으로 나타났고, 안경구매 소비자의 브랜드자산 인식에 대한 구매만족 및 구전의도는 브랜드에 대한 지각된 품질, 브랜드 인지도, 브랜드 이미지 순으로 나타났다. 결 론 : 안경구매자의 구매만족과 구전의도를 향상시키기 위해서 고객서비스 및 디자인에 대해 경쟁력을 갖추어야 하며 브랜드에 대한 지각된 품질을 향상시키는 노력이 필요하겠다.

본 연구에서는 서로 다른 지역에서 재배된 장뇌삼 8 품종과 밭에서 재배된 재배인삼 등 총 9개체에 대해 장 뇌삼 품종들 간의 유연관계를 분석하였다. RAPD분석에 사용한 random primer는 총 40종류(OPA 1～20, OPB 1～20)였으며, 이 중 34개가 각기 다른 지역에서 재배된 품종간의 집단을 형성하여 9개 품종간 유연관계를 밝히 는데 유용하였다. 유연관계를 분석한 결과, 홍천과 재배 인삼, 의성과 금산, 진안과 풍기와 강화, 상주와 안동 4개 의 그룹으로 구분되었으며 이는 다시 2개의 그룹「홍천- 재배인삼-의성-금산」,「풍기-강화-상주-안동」으로 구 분 되었다. 9개 지역에서 수집한 품종간의 유사도 값은 최저 0.30, 최고 0.53으로 나타났다. RAPD방법은 사용법 이 간단하고 소요시간이 적게 소요될 뿐만 아니라 적은 양의 DNA시료로도 분석이 가능한 검정법으로 형태적인 차이가 구별되지 않는 장뇌삼 품종 간의 유전적 유연관 계를 밝히는 데 유용한 방법임을 알 수 있었다. 그러나 품종별 계통유연관계를 보다 정확히 분석하기 위해서 AFLP 또는 Molecular Maker를 이용하거나 계통분류에 널리 이용되는 핵, 엽록체 DNA의 유전자 염기서열 비교 와 같은 정밀한 분자계통학적 연구가 수행되어져야 할 것으로 사료된다.

The purpose of this study was to develop the national park visitor counting system using the ubiquitous sensor network. This system is composed of a sensor node, sink node, gateways, CDMA module, server, and clients. The results of the study were: 1) stable data transmission distance was possible within 100 meters between sensor nodes, 2) the developed counting sensor system showed a network communication stability level of 88.3 percent in 1.2m wide trails. When installed in concentrate use areas or forks of national parks, the visitor counting system will not only contribute to provide reliable visitor counting, but also to improve the quality of national park visitor service, to manage park facilities and natural resources more efficiently, to achieve an information oriented national park system.

The Monitoring System developed in this study was designed to help manage the recreational forests by gathering data on visitors' profiles and their opinions about recreational use and related facilities. This data could identify for changing situations in forest recreation demand as well as providing information on planning the management and use of the forest areas in advance. The standardized questionnaire had contained visitor profiles, activities, distribution of use by area, distribution us by time, duration of the visit, expenditure of visitors and information on visitor satisfaction and motivation. Also, the questionnaire had included the evaluations visitors' perception of facilities in order to identify the importance and performance of the various facilities, such as recreational and educational facilities, accomodations, directional signs as well as infrastructure. The monitoring system was developed in the object-oriented programming (OOP) environment. Microsoft Visual Basic 6.0 for the program language, Microsoft Access, and Excel program were used to develop the system. The monitoring system was composed of data input, database, and data analysis system. Once data were put into data input system, it automatically transferred to database, and it eventually produced the results of statistical analysis with one step procedure. This study was integrated with facilities and visitor monitoring system to identify the visitor impact at the recreational forests. In addition, this monitoring system would provide necessary and useful background information for management on recreational use of natural resources in a practical manner.
