A simulation model of the 2010/11 foot-and-mouth disease (FMD) epidemic in the city of Andong, Republic of Korea was constructed to evaluate the epidemiologic effectiveness of FMD-control strategies. Seven FMD-control strategies were evaluated with respect to a number of epidemiologic indicators relating to the outbreak, including the number of infected animals, number of infected farms, and epidemic duration. The FMD-control strategies in the model consisted of pre-emptive slaughtering, movement restriction, and vaccination; however, levels of each control option differed. The constructed model was not perfectly representative of the 2010/11 FMD epidemic, although it was considered to mimic the actual FMD epidemic in its prediction of two outcomes: the median number of simulated FMD-detected farms was 294 (range 207–515), which was close to the number of farms detected (299) during the actual FMD epidemic (x2=87.239, df=98, p = 0.774); and the simulated epidemic curve was visually similar to the actual epidemic curve of the 2010/11 FMD epidemic. The effectiveness evaluation of simulated FMD-control strategies emphasized the amount the FMD outbreak size could have increased if the radius of the pre-emptive slaughtering area or the duration of movement restriction were decreased.

전라남도 해남군 문내면 일대에 축성된 전라우수영 성곽의 부재를 대상으로 암석학적 연구를 수행하고 산지를 추정하여 보수정비를 위한 자료를 제공하고자 한다. 연구대상인 전라우수영은 2016년에 사적 제535호로 지정되었으며 성곽의 잔존구간은 약 15% 정도로 보존관리가 필요한 실정이다. 이번 연구에서는 성곽 부재에 대한 암석기재적 특징을 바탕으로 축성에 사용된 암석을 분류하고 사용비율을 산출하였으며 동시에 전암대자율을 측정하였다. 채취한 성곽 시료의 현미경관찰로 광물 구성 및 조직 등을 파악하였으며 주변지역에 대한 지질조사를 통해 축성 재료의 가능성이 있는 주변암과 비교하였다. 연구 결과, 성곽 부재는 크게 응회암류와 기타 암석으로 구분할 수 있으나 대부분이 응회암류이며 세부적으로는 응회암, 화산력 응회암, 화산력암이다. 부재로 사용된 비율을 살펴보면 화산력 응회암이 60.3%로 가장 많이 사용되었으며 이어서 응회암(34.7%), 화산력암(2.5%) 순이다. 전암대자율 측정 결과 응회암류는 1×10−3 SI unit 이하의 낮은 값과 1-14×10−3 SI unit의 높은 값을 보이는 유형으로 구분할 수 있다. 주변암은 응회암이 우세하나 위치마다 기재면에서 차이를 보이며 그 외의 응회암류는 화원면 신덕리 일대에 분포한다. 암석기재적인 특징과 전암대자율값, 채석산지의 가능성을 고려하면 부재의 응회암은 문내면 동외리, 화산력 응회암은 화원면 신덕리 일대가 산지로 추정된다. 추가로 축성 재료의 기준 설정을 위해 성곽의 주요 부재를 대상으로 물성시험을 수행하였으며, 압축강도 면에서 응회암이 약 156 MPa의 양호한 값을 보였다. 물성시험 결과와 부재의 암종 별 사용량을 종합하면 성곽의 보수정비 시 대체석으로는 응회암이 적절할 것으로 판단된다.

Riptortus pedestris (Fabricius) has caused severe agricultural damage in Asian regions. To clarify genetic relationships among different populations of R. pedestris in Korea, 294 COI sequences were generated from 294 individual samples collected in 42 local regions. In total, 36 haplotypes were detected from the 294 COI sequences, and the genetic distances among the 42 local populations ranged from 0.00 % to 1.50 %. In the AMOVA results, a variability of more than 98 % was observed within populations, and the median joining (MJ) networks revealed that R. pedestris has expanded by crossing the nine geographical groups. Most of the samples shared one haplotype, H2; however, some samples obtained from the same regions displayed slight genetic differences. These results indicate that R. pedestris have undergone a series of genetic variations.

Soft power is an important part of national comprehensive strength, many countries has taken all kinds of measures to improve the level of soft power, but there are big differences of efficiency. Important reason lies in the cultural communication strategy. This paper takes China and Republic of Korea as examples to sum up the influence of cultural communication strategy on soft power. The common characteristics of the two countries is the importance of government. However, due to differences in cultural industrialization and dissemination content, there are still great differences in the effect of cultural transformation into soft power. Overall, Republic of Korea has more successful experiences and China is in the process of development.

Biodiversity has globally declined because of various drivers, and the loss of biodiversity encroaches ecosystem services resulting in more serious socio-economic and environmental problems in low-income or underdeveloped countries where local livelihood is highly dependent on ecosystem services. Official Development Assistance (ODA) from developed countries may help address the negative drivers of biodiversity loss. However, little researches on ODA related to biodiversity issues in the Republic of Korea are available. This study was conducted to review the current status of ODA related with biodiversity issues provided by Korea. We used ‘Green ODA’ guided by the Korea International Cooperation Agency (KOICA) and ’Creditor Reporting System (CRS)’ code of the Organization for Economic Cooperation and Development (OECD) to identify and analyze biodiversity-related ODAs. As a result, ODAs for biodiversity provided by Korea were belonged to two of five categories of the Green ODA. The total amount of the overall ODAs and Green ODAs have increased steadily since the 2000s. However, the amount of biodiversity-related ODAs had greatly changed over time, and its proportion to overall ODA budgets had remained low. This may be largely because the ODAs for biodiversity had been implemented on a short-term basis, not for systematic long-term projects. In order to meet the global trend for biodiversity conservation, it is necessary to expand the total amount of ODAs for biodiversity, establish long-term plans, and maintain the continuity of biodiversity-related ODA projects.

ZnO micro/nanocrystals with different morphologies were synthesized by thermal evaporation of various zinc source materials in an air atmosphere. Zinc acetate, zinc carbonate and zinc iodide were used as the source materials. No catalysts or substrates were used in the synthesis of the ZnO crystals. The scanning electron microscope(SEM) image showed that the morphology of ZnO crystals was strongly dependent on the source materials, which suggests that source material is one of the key factors in controlling the morphology of the obtained ZnO crystals. Tetrapods, nanogranular shaped crystals, spherical particles and crayon-shaped crystals were obtained using different source materials. The X-ray diffraction(XRD) pattern revealed that the all the ZnO crystals had hexagonal wurtzite crystalline structures. An ultraviolet emission was observed in the cathodoluminescence spectrum of the ZnO crystals prepared via thermal evaporation of Zn powder. However, a strong green emission centered at around 500 nm was observed in the cathodoluminescence spectra of the ZnO crystals prepared using zinc salts as the source materials.

베트남은 3,444 가 넘는 해안선, 수천 개의 섬 그리고 길이 4260 이상인 2,360개의 강과 수로가 있는 해양국이다. 선박 에 의한 유류수송의 빈도와 수송량이 증가하면서 기름유출사고의 가능성이 과거 어느 때보다 높아지고 있다. 해상에서의 연료유 및 화 물유의 유출은 해양생태계, 연안자원 및 인간건강은 물론 사회 경제에 대하여 광범위하고 장기적인 영향을 미친다. 본 연구는 20년 동안의 기름유출사고 건수와 유출량과 같은 베트남의 해양기름유출 현황 그리고 기름유출대응(OSR)에 대한 국가체제 등과 같은 국가 대응체계에 관한 전반을 보여줄 뿐만 아니라, 특히 베트남과 한국 사이의 국가기름유출대응체제를 비교함으로써 기름유출사고에 대응 하여 베트남의 국가역량을 강화하기 위한 권고안을 제시하고자 한다. 그 결과, 베트남의 해양기름유출사고 건수와 유출량은 한국의 하 락 추세와는 대조적으로 상승 추세를 보였다. 이는 베트남의 연안 해역에서 실제적 기름유출 가능성이 높다는 것을 의미한다. 따라서 베트남의 국가기름유출대응역량을 강화하기 위한 3가지 주요 권고안을 다음과 같이 제안한다. 즉 OPRC협약의 수락 · 이행 그리고 유류오염으로 인한 피해 및 손실을 보상하는 국가기금의 조성과 같은 기름유출사고에 대비하고 대응하기 위한 법률제도를 포함한 국 가기름유출대응 시스템을 강화하기 위한 방안의 개발; 일관된 보고, 경보 및 모니터링 시스템의 강화; 표준 교육과정 내용으로 구성된 교육 및 훈련 프로그램의 개발을 제안하고자 한다.

In this presentation,the national vector management systems and studies will be addressed.Key words : Disease vectors, National management, the Republic of Korea, climate change

Suillus granulatus is an ectomycorrhizal fungus that is associated with pine roots. S. granulatus is edible mushroom and known as the weeping bolete. S. granulatus is similar to S. luteus, but S. granulatus has a ringless stalk. We investigated in the growth characteristics of the 4 strains of S. granulatus with growth medium, temperature, and cellulase enzyme activities. NIFoS 1211 and 2701 showed the highest growth on PDA and NIFoS 1997 produced abundant mycelia on MMN. NIFoS 2615 was grown well on SDA. In spite of same species, the optimal media were different according to habitat of fruit body. The optimal temperature for mycelial growth of all strains was 25oC and NIFoS 2615 was also grown well at 30oC. All of strains on MMN liquid medium were typically grown at pH ranges from 5.8 to 6.2. The dry weights of S. granulatus strains were measured according to different inorganic nitrogen sources. All strains showed the highest dry weight on MMN and showed little difference on none contained nitrogen source, ammonium and nitrate media. We measured cellulase activity on carboxymethylcellulose (CMC) agar plates, and determined clear zone according to pHs. The 4 strains of S. granulatus showed the positive reactions in cellulase activity. All strains formed the height clear zone at pH 6.
