전시컨벤션산업은 고부가가치 서비스산업으로서 고용을 창출하고, 지역 경제를 활성화시키며, 외화획득과 세수증대를 가져올 뿐만 아니라, 개최지역의 국제적 인지도 향상과, 이미지를 개선시켜 해당 지역의 발전에 순기능 역할을 한다. 따라서 본 연구에서는 이러한 환경 속에서 전시컨벤션산업에 종사하는 기업들(원청업체)이 전시컨벤션산업의 여러 분야에 활용하고 있는 아웃소싱 업체 및 조직원의 서비스품질이 이를 활용하는 기업들(원청업체)의 기업성과 및 고객만족에 미치는 영향을 살펴보았다. 실증연구를 위한 모집단은 서울, 경기, 충남지역 기업 중 여러 산업분야에 아웃소싱을 활용하여 전시회 혹은 컨벤션에 참여한 기업들의 임직원 350명을 대상으로 설문조사를 실시하여 성실하게 응답한 267매를 통계조사에 활용하였고 자료 분석은 데이터 코딩과 클리닝 과정을 거쳐 SPSS 20.0 통계패키지를 사용하였다. 이를 통해 전시컨벤션 산업에 있는 여러 기업들이 주요 핵심 업무를 담당하고 있는 직원들을 제외하고는 거의 아웃소싱업체에 의뢰하여 각종 전시회, 회의 및 관련 프로그램 등을 진행하고 있고 아웃소싱 인력이 전시컨벤션산업의 행사접점에 위치하여 있어 아웃소싱업체 및 종업원의 서비스 품질이 기업의 성과와 고객만족에 미치는 영향이 클 수밖에 없으므로 이러한 서비스품질의 주요 결정요인 및 중요성을 알아보았고 원청업체와 아웃소싱업체, 그리고 근무지회사가 아웃소싱의 서비스품질을 효과적으로 관리하기 위한 방안을 모색하였다. Holding conventions and exhibitions are deemed as a highly valued-added services. The conventions and exhibitions industry (CEI) contributes to the development of the region in which the venues are located by creating jobs, boosting the local economics, attracting dollars and increasing tax incomes. At the same time, the international awareness of the region rises after holding an international exhibition or convention. This study investigated the effects of outsourcing services quality that employed by corporations organizing conventions and exhibitions on business performance and customer satisfaction of organizing corporations. It was found that many convention organizing corporations relied on outsourcing services for the most of the process. Given that the staff members of outsourcing companies serve as the major source of services for events, the quality of their services has much effects on the business results of hiring corporations. In this study, major factors influencing the service quality and the importance of the service quality were addressed. And the ideas for effective method for controlling the outsourcing sources were also suggested for hiring corporations and outsourcing companies.

본 논문은 다단연소사이클 엔진의 연소실 내벽을 고온, 고압의 환경으로부터 보호하기 위한 열차폐 코팅 공정 개발에 관한 내용이다. 기존 연소기 내벽에는 열차폐 특성이 우수한 Zr 기반의 세라믹용사코팅을 적용했지만, 세라믹의 특성상 연소실 내벽(금속)과 열팽창계수 차이로 인해 박리가 발생할 수 있다. 때문에 로켓 선진국에서는 열차폐 효과를 다소 희생 하더라도 밀착력 향상을 위하여 금속계 코팅인 Ni-Cr 도금을 적용하고 있다. 본 연구에서는 연소기에 적용 가능한 상향 순환식 유동셀을 적용한 도금조를 개발했으며, 반복적인 공정 개선을 통해 도금 두께 100㎛이상, ±10%의 두께 균일도를 만족하는 Ni, Cr 도금 공정조건을 확립했다. In this paper, the process of electro Ni and electro Cr plating is studied for the purpose of thermal barrier to protect the inner wall combustion chamber. The chamber is under the environment of very high temperature and high pressure when propellants burn in there. As one of the thermal barrier coatings, Zr-based thermal spray coating has been applied to the chamber. However, peeling of coating layer can occur under such a hard condition because of the difference of thermal expansion coefficients between the ceramic and the metallic wall. We study the characteristics of Ni-Cr coating and establish its process. It is found that the thickness of over 100 ㎛ of Ni and Cr coating layers with the uniformity of ±10% can be obtained with the used of as-developed plating bath.

The relationship of cartilage canals to initial osteogenesis of primary ossification center of developing vertebrae in human fetuses ranging from 50mm to 260mm in crown rump length was studied by light and electron microscopy. The cartiage canals of the thoracic vertebrae were first observed at 60mm fetus. Cartilage canals were identified as vascular channels arising from perichondrium surfaces. A number of cartilage canals were observed around the primary center of ossification at 80mm fetus. At 120mm fetus, cartilage canals of the bodies of vertebra were increased. Eventually the canals were eroded from the main medullary cavity and remained at only peripheral regions of growth cartilage. Superficial, intermediate, and deep canals were identified by the characteristics of cartilage cells. Fibroblasts, undifferentiated mesenchymal cells, and vacuolated macrophages were observed adjacent to the matrix of resting cartilage cells in the superficial canal. Fibroblasts and mesenchymal cells were densely packed at the tip of canal, giving an epithelial appearance to the clustered cell in the intermediate canal. Vacuolated macrophages were in contact with matrix of hypertrophied cartilage. The thick-walled vessels in the intermediate and deep canals consisted of typical endothelial cells, but in the newly formed vessels contained mesenchymal cells and fibroblasts incorporated into the vessel wall. During lengthening of cartilage canal, the matrix of cartilage cells were invaded by newly formed capillaries and vacuolated macrophages. At the deep canal, the lateral wall of the canal terminated in matrix containing calcified cartilage. The mesenchymal cells began to differentiate into osteoblasts adjacent to the calcified matrix. The results indicate that the connective tissue cells within the cartilage canals proliferate and differentiate into osteoblasts at the site of primary ossification center.

에틸포메이트는 해충을 방제하기 위한 훈증제로서 사용되어 왔다. 그러나 농산업에서 해충을 박멸하기 위하여 사용된 이 물질이 일으키는 훈증독성의 작용점에 대해서는 많은 연구가 수행되지 않았다. 본 연구에서 저자들은 복숭아혹진딧물 약충에 에틸포메이트를 훈증 처리 하였을 때 추측 가능한 작용점들을 제시하였다. 에틸포메이트 훈증 처리 후 복숭아혹진딧물 약충에 대한 생화학 및 분자적 수준에서의 변화를 측정하였다. Cytochrome c oxidase (COX)의 활성은 에틸포메이트 훈증 처리된 복숭아혹진딧물 약충에서 약 2배 이상 증가하였다. Acetylcholinesterase (AChE)의 경우 에틸포메이트의 훈증 처리농도가 증가됨과 함께 유전자 발현이 감소되었다. 이 두 발견은 COX와 AChE가 주요한 에틸포메이트 훈증독성의 작용점임을 시사하였다. 이 결과들과 함께 MALDI-TOF MS/MS를 이용하여 지질대사체를 분석한 후 2배 이상 증감을 보인 9종 인지질들을 동정하였고 이들이 세포막 조성에 변화를 유발함을 밝혔다. 결론적으로 복숭아혹진딧물 약충에 대한 에틸포메이트의 훈증독성은 COX 활성 변화, AChE 발현 변화, 그리고 인지질의 생성 변화에 기인하였다. Ethyl formate has been used for the control of insect pests by fumigation. However, there were not many reports to show its target site of fumigant toxicity on insect pests since its first use in the agricultural industry. In the present study, we showed the presumable target sites of ethyl formate fumigation in insect pests using Myzus persicae nymphs. After ethyl formate fumigation, the nymphs of this species were collected and the changes at the biochemical and molecular level were determined. The activity of cytochrome c oxidase (COX) was approximately two-fold higher after ethyl formate fumigation. In addition, the expression levels of acetylcholinesterase (AChE) decreased gradually with increasing ethyl formate concentration. These two findings suggested that COX and AChE might be the major target sites of ethyl formate fumigation. In addition to these results, the analysis of lipid content using MALDI-TOF MS/MS identified 9 phospholipids differently generated 2-fold higher in the ethyl formate-treated nymphs than that in the control nymphs, thereby leading to changes in cell membrane composition in M. persicae nymphs. Therefore, the ethyl formate fumigation caused lethal effects on M. persicae nymphs by changing COX activity, AChE gene expression, and phospholipid production.

In this paper, we focus on the Food Safety Incident Management Issues in China. Facing with a series of food safety incidents in recent years, Chinese government does make a lot of effort to solve problems, ensure food safety and protect consumers from dangers. But still the areas in which further improvement might be considered as follows: First is to reduce the number of food safety incidents by improving the overall food safety level. Second is that the local administrative departments should continue to set up food safety publicity, improve the public ability to identify toxic plants and animals, increase public awareness of food safety according to the local diets, living habits and climatic characteristics. Third is to emphasize on prevention and control of food safety incidents. Fourth is that enterprises or related producers must at least have a moral bottom line as production progress is the first basic step of all manufactures. The last most important reform would be to allow the effective operation of the existing system of private civil litigation and bankruptcy that would allow injured parties to take action independent of the government, giving the producers a warning to act legally.
