  • 배를 캐나다 등 외국에 수출할 시는 수출 상대국의 검역요건에 맞추어 주어야 한다. 수출국 특히 캐나다에 수출되는 배의 검역상 문제점을 찾아 그 해결법을 제시하고자 수출 조건에서 수출 단계별 검역규제병해충을 조사하였다. 조사 결과 복숭아명나방과 복숭아순 나방이 발견되었으나 이들은 저온처리로 인하여 모두 사멸되었다. 해충은 복숭아심식나방류 유충이 과실로 이동되는 시기에 방제를 소홀히 한 생산지 과실에서 발견되었으므로 복숭아명나방 등 심식나방류 유충이 과실로 이동되는 시기에 예찰을 철저히 하여 적기방제 하는 것이 필요하다. 한편 병원균은 과실의 선과 작업과 이동할 때 생긴 압상, 자상 등 상처를 통하여 Penicillium sp. 및 Alternaria sp.의 부생균이 감염된 것이 발견되고 검역병원균은 발견되지 않았다. 그러나 이들 병원균도 비록 비검역병원균이라고 하지만 부패과실이 일정비율 초과할 경우 수출자가 수입자에게 이를 보상하여야 하므로 수출배 중 외피가 얇은 황금배 등은 수확 후 운송과정과 선과장 선과 작업 중에 특별한 주의가 요구된다.

  • Cancer has been the leading cause of death in Korea for the last 30 years. Cancer patients' 5-year survival rate between 2005 and 2009 was 62.0%, representing a highly advanced standard of care, as much as developed countries in the EU and the US. The Korean government formulated its first 10-year plan for cancer control in 1996 and has been carrying out a second 10-year plan for cancer control since 2006. But despite the Korean government's efforts, the cancer burden in Korea continues to increase. Many separate laws have gone into effect concerning the management of carcinogen exposure. However, there are no integrated regulatory laws or management systems against carcinogen exposure in Korea. Dead zones remain where carcinogen exposure cannot be controlled properly in Korea. In this paper, we suggest the need to establish a national carcinogen list based on international harmonization as a prerequisite for a paradigm shift in cancer control policy from treatment to primary prevention.

A total of 98 species belonging to 75 genera and 36 families are enumerated; all species are provided with habitat data (bathymetric distribution and bottom sediments character), given separately far living and dead (empty shells) specimens, and some with taxonomic and zoogeographic comments. Fifty-six species are illustrated with photographs. Astarte hakodatensis Yokoyama, 1920 (Astartidae), Nitidotellina pallidula (Lischke 1871) (Tellinidae) and Lyonsia nuculanoformis Scarlato in Volova et Scarlato, 1980 (Lyonsiidae) are found to be new to the Korean fauna, and the genus Salaputium Iredale, 1924 (Crassatellidae) with one species Salapurium Iredale, 1924(Crassatellidae) with one species Salaputium cf. unicum Hayami and Kase, 1993, previously described as being found only from submarine caves in the Ryukyu Islands, is recorded as being found in the East Sea(Sea of Japan) for the first time.

  • In September 2017, an outbreak with high mortality, which showed the typical signs of ND, occurred among a flock of more than 2000 Eurasian collared doves in Konarak, southeast of Iran. A confirmed pigeon paramyxovirus type 1 strain was isolated from the brain tissues of the dead doves. The isolate, which was called Pigeon/Iran/Konarak/Barin/2017, was classified as a highly velogenic NDV. Complete genome sequencing and phylogenetic analysis showed that the isolate belonged to subgenotype XXI.2, which has never been reported from Iran before. The isolate had the highest homology (96.15%) with early 2010s Italian isolates. Further studies will be required to understand the diversity better.

  • Eurasian eagle owl (Bubo bubo kiautschensis) is a natural monument (No. 324) and is also classified as an endangered wildlife grade II the Ministry of Environment of Korea. Eurasian eagle owl is threatened by the human being. But the efficient rescue and treatment for Eurasian eagle owl are still problematic, due to lack of basic data. In this study, to obtain basic resources for establishing more efficient rescue system, we held a physical examination and measured size physical part. In addition, we analyzed blood sample and feces samples and autopsy. We conduct the physical examination with measuring tapes and scales for 16 live features and 11 dead features. After inhalation anesthesia take the blood samples from wing vein. Blood samples are analyzed in hematologic and chemistric methods. We collected the feces through individual floor of cages from 12 live features and conducted the feces analysis. Autopsy was conducted for 11 dead samples. In physical examination, the mean body weight and total length of live features was 2.26${\pm}$0.35kg, 61${\pm}$2.38cm, the mean body weight and total length of dead features was 1.57${\pm}$0.51kg, 59.31${\pm}$3.51cm. Mean PCV was 46.57${\pm}$4.97%, while mean TPP was 3.49${\pm}$0.57g/dL. In feces sample analysis, 9 of 12 owls(75%) were infested by gastrointestinal helminths. The infection rates were: Trematoda (41.7%), Capilaria sp.(66.7%), acanthocephalans (25%). In autopsy, we confirmed 11 features were infested by duplicated infection of more than 2 helminths. Result of this study will be used for establishing reference range for physical features, blood analysis in Eurasian eagle owl. Therefore, to obtain basic resources for establishing more efficient rescue system, we have to make long-term conservation plans for Eurasian eagle owl.

  • On a farm with 6 Korean beef cattle, an adult cow and a calf suddenly died while eating. At that time, hair was pressed upon the stanchion facilities where the adult cow was fed. Two dead cattle were submitted to the Animal and Plant Quarantine Agency for disease diagnosis. Grossly, the mouth of the adult cow was full of feed that had been eaten before death, and there was a foamy fluid in the calf's trachea. Both hemorrhages were observed in the muscles, as well as in the internal organs such as the liver, lungs, and heart. Ruminal mucosa was easily peeled off. Histopathologically, both muscles and internal organs showed severe hemorrhages. In particular, affected muscles were shown segmental and band-like patterns of myonecrosis, disappeared some myocytes, burned hair follicles, and irregular surface of skin. Severe hemorrhages of muscles and internal organs were consistent with previous reports. Easily separated mucosa of rumen and muscle lesions were very characteristic. We determined electrocution according to the pathological findings, laboratory results, and traces of accidents. This report will help to understand of pathological lesions of electrocution. Furthermore, this case suggests that the electrical wires and devices must be installed and handled carefully during the construction of the cowsheds care.

  • 본 연구는 우리나라 특산식물인 히어리 군락이 지리산 국립공원 동부지역에 대규모로 분포하고 있는 것을 처음으로 발견하여 군락지의 분포 및 맹아지 특성 그리고 군락의 보호대책을 위한 기초자료를 축적하고자 수행되었다. 각 계층별 중요치는 교목층에서 소나무(134.15) 일본잎갈나무, 산벚나무, 비목나무, 신갈나무 등이 우점하였고 아교목층에서는 히어리, 거제수나무. 비목나무, 졸참나무, 노각 나무 그리고 관목층에서는 히어리가 우점하였으며 그 외에 철쭉꽃, 진달래, 생강나무 등이 출현하였다 그리고 맹아지 특성은 1개 방형구(25m2)에 평균 17.75개의 주간이 형성되고 1개 주간당 맹아지 수는 평균 6.00개 고사지는 2.80개로 조사되었다. 흉고직경급별 분포에서 생장지의 경우 흉고직경 1.0-4.0cm 구간에서 전체의 64.78%를 차지하였으며 대부분 2.0-3.0cm 구간에서 54.74%를 차지하여 히어리 군락의 중심계급이었다 흉고직경 1.0cm 이하의 고사지가 전체의 53.16%를 차지하였는데 이는 근주에서 돋아나는 1년생 맹아지가 대부분 고사하였기 때문이었다 특히 히어리의 번식습성은 실생묘에 의한 번식도 가능하지만 본 조사지에서와 같이 수관이 울폐된 지역에서는 주로 근맹아에 의한 번식을 더 선호하는 것으로 나타났다.

  • Water status of intact plants has been optically estimated by measuring reflectance at the wavelengths 1,450 nm and 1,900 nm based on their signal strengths. Although another water band at 970 nm is considered to have very small signals, the band apparently lies within the detection range of inexpensive spectrometer and plain charge-coupled device (CCD) camera used in wild fire studies. However measurement of the reflectance at 970 nm has been rarely applied to estimate the water status of dead plant materials such as fallen branch, twig, and leaf. To test the possibility of applying water reflectance at 970 nm to estimate the water content (WC) in leaf litter, the reflectance in various WC values were measured in the leaf litter of three Quercus species (Q aliena, Q aliena, Q mongolica, and Quercus variabilis). The results showed that the WC in the leaf litter can be determined by reflectance water index (WI) in the three Quercus species ($WC=1,450{\times}WI-1,378.8$, r=0.865). However, there was no interaction effect in the relationship between WI and WC among the litter of the three Quercus species.
