2018년 6월 1일부터 9월 17일까지 109일 동안, 총 112개 국외 발 국내 입항 선박을 대상으로 편승자 해충(hitchhiker insect pests)에 대한 모니터링을 실시하였다. 그 결과, 총 336개체의 편승자 해충을 확보하였으며, 이를 통합 분류학적 종동정 방법(integrative identification method)을 이용하여 9목 47과 159종으로 동정하였다. 이 중 총 3목 9과 14종의 한국 미분포종(not-distributed species)이 확인되어 보고하며, 검출된 미분포종에 대해서 침입종(invasive species) 내지 침입 가능종(invasive likelihood species)에 대한 위험성 평가를 위한 data sheet를 제공하였다. 또한, 미기록(unrecorded species), 미보고종(unreported species) 내지 신기록종(new recorded species)과 용어의 혼동을 피하기 위하여 본 연구에서는 미분포종(not-distributed species)을 제안하여 사용하였다.

Recently, with the development of computer technology, field instrument and control system using in industrial fields have changed from mechanical, electrical systems to digital electronic systems. Distributed control system(DCS), control functions are dispersed for grading up reliability and informations are combined fur effective management has been developed and sold. As this system has been enlarged and complicated, it is difficult to testing the system and very important to verifing functions systematically. In this report, function test procedure which is performed spontaneously by domestic or foreign DCS manufacturer was searched and analyzed. As its results, the test procedure of DCS functions were proposed. The proposed procedure was applied to DCS being used for a thermal power plant. The function test for DCS requires continuous and dynamic input/output signals, therefore we proposed the method to compose virtual plant which simulate the DCS functions with. And we suggested the test procedure of each DCS function.

In tobacco, in vitro pollination has been successfully applied to overcome interspecific incompatibility. The use of this technique will make it possible to introduce DNA into pollen tubes just before fertilization. In this study, we showed improvement of the efficiency of in vitro self-pollination and introduction of foreign genes into pollen tubes by the method of polycation. A plasmid harbouring the GUS gene was introduced into pollen grains and pollen tubes, which had incubated on pollen germination medium(PGM), by polyornithine method. Transient expression of the GUS in pollen grains and pollen tubes that were treated with 0, 2, 5 and $10{\mu}g/m\ell$ DNA was observed. In results, combination of the techniques of polyornithine and in vitro pollination was efficient new technique for genetic transformation through fertilization processes.

관통성 손상 후 외부 이물질이 신체 조직 내 남아 있는 경우는 응급실을 방문하는 주요 원인 중의 하나이다. 수부에서 발견되는 이물질은 대부분 외상에 의해 발생하며 식물성 조각들이 가장 흔하고, 다음으로 유리조각, 금속조각의 순서로 발생한다. 특히 나무조각이나, 플라스틱 조각 등은 방사선투과성(radiolucency)을 가지고 있어 단순 방사선 사진으로 쉽게 발견하기 어려운 경우가 많아 외부 이물질을 찾는 것이 어려울 뿐만 아니라 일부 제거하더라도 이물질의 잔존 여부를 감별하기가 어렵다. 이에 저자들은 나무가시에 수상 당한 후 1차 의료기간에서 일부 나무가시를 제거 후 잔존 나무가시를 발견하지 못하고 수상 4주 이후 초음파을 이용하여 잔존 이물질을 진단하여 수술적으로 치료 후 동통의 감소를 보인 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

이 논문은 한국이 체결한 자유무역협정(FTA)이 해외직접투자를 추진하고 있는 한국기업들의 생산성에 어떠한 영향을 미치는 가를 분석하기 위해 작성되었다. 특히 기업규모에 따라 영향의 차별이 나타나는지를 보기 위해서 기업대상을 대기업과 중소기업으로 나누어서 FTA 체결을 전후로 총요소생산성의 변화가 나타나는지를 조사하였다. 조사기간은 2002년부터 2010년까지로 하고 국내 모기업과 해외 현지법인의 기업별 자료를 이용하였다. 분석결과 FTA를 체결한 나라들에 투자한 한국기업들 중 중소기업의 모회사와 해외현지법인은 FTA 발효후 생산성이 상승하는 것으로 나타났고, 대기업의 경우는 유의성을 발견하지 못하였다. 이는 자유무역협정이 대기업에 유리한 영향을 줄 것이라는 일반적인 견해와 다른 것이다. 중소기업의 생산성이 상승한 배경에는 FTA 발효이후 모회사는 자본집약적 성향이 더 강해졌고, 해외현지법인의 경우는 한국으로의 수출이 증가한 것 등이 작용하고 있음을 발견하였다.

A 3-year-old spayed female beagle dog was presented with epiphora, severe hemorrhagic and purulent ocular discharge in the right eye (OD). A reflux of the discharge through the other canaliculi, associated with signs of chronic inflammation, was observed on cytology. Dacryocystorhinography revealed retention of contrast media ventral to the lower punctum, indicating complete obstruction and the potential presence of radiolucent foreign body. Ocular discharge subsided after the first treatment, including flushing of the nasolacrimal duct and application of topical antibiotics and corticosteroids, but clinical symptoms of the dacryocystitis waxed and waned thereafter. Surgical treatment was delayed for 8 months due to Dirofilaria immitis infection, and topical treatment and monthly flushing were maintained. On the day of operation, a foreign body was released through the fistula, while flushing for disinfection under general anesthesia, just before the surgery. Dacryocystectomy was performed to remove necrotic tissue and residual foreign body around the nasolacrimal cyst. Upon histopathologic findings, the removed foreign body was considered to be a plant, and the nasolacrimal cyst was comprised of chronic active ulcerative inflammation and necrotic tissues. At the 1-week recheck, improvement of epiphora and ocular discharge and healing of the surgical site was noted. In conclusion, nasolacrimal duct foreign body can be considered in recurrent dacryocystitis, despite nasolacrimal flushing and topical medication. In this study, dacryocystectomy was curative without recurrence of dacryocystitis or epiphora.

The purposes of this study was to investigate accuracy and indigenity of landscape plant species in planting design and construction at housing complex and offer basic data for improving precision of planting construction. The scientific name of landscape plant species was described in planting drawings at only two sites among twelve survey sites. According to analysis on indigenity of plant species in planting drawings, it was found that the component ratio of foreign species was the highest and the component ratio of native species at public housing complex was the lowest. The component ratio of landscape plant species in planting construction was severely differed to that of planting drawings. Also the component ratio of cultivar was higher than that of planting drawings due to planting of sevveral cultivars for one species in planting drawings. In the result of accuracy analysis on landscape plant species in planting construction, it was found that mean ratio of inacccurate species was 33.2% at public housing complex, 29.6% at local company housing complex and 26.4% at nationwide company housing complex. It was found that several cultivars were planted for one species in planting drawings. The representative species which were planted by several cultivars were Camellia japonica, Rododendron spp., Prunus spp. and Magnolia spp. and so on. In order to promote the precision and speciality of planting design and construction, scientific and cultivar name of plants should be described in planting drawings.

Almost domestic power plants are being operated by foreign distributed control system. Many korean power plants are being operated over their lifetime so they need to be retrofitted. So we are developing the distributed control system to solve this problem by our own technique. The simulator was already made to verify the reliability of the algorithms. The unit loop function tests of all algorithms were finished in the actual distributed control system for installation of power plant and their results were satisfactory. The unit loop function tests are for each unit equipment algorithm. So the total operation tests will be made with all algorithms together in the actual distributed control system to be applied to power plant. When the verification through all tests is finished, algorithms with hardware will be scheduled to be installed and operated in the actual power plant. This research result will contribute to the safe operation of the deteriorated power plant and korean electric power supply as well as domestic technical progress. This entire processes and results for the development are written for the example of boiler feedwater master algorithm out of all algorithms in this paper.

Agrobacterium-mediated gene transfer has recently been developed to improve rice transformation. In this study, 3 different transformation methods were tested including soaking, co-cultivation, and vacuum infiltration. Agrobacterium tumefaciens GV3101 harboring the binary vector pGreen:: LeGSNOR was used in this experiment. This study aimed to identify the most appropriate method for transferring LeGSNOR into rice. Vacuum infiltration of the embryonic calli for 5 min in Ilpum resulted in high transformation efficiency based on confirmation by PCR, RT-PCR, and qRT-PCR analyses. In conclusion, we described the development of an efficient transformation protocol for the stable integration of foreign genes into rice; furthermore, the study results confirmed that PCR is suitable for efficient detection of the integrated gene. The vacuum infiltration system is a potentially useful tool for future studies focusing on transferring important genes into rice seed calli, and may help reduce time and effort.
