A total of 41 Salmonella (S.) strains were isolated from pigs suffered with severe watery diarrhea and were tried to identify by both matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and polymerase chain reaction (PCR) analysis. Fibrinous exudate and ulceration in the large intestine were prevalent in gross observation, and variable degrees of enteritis were observed in the histology of large intestines. Subsequent polymerase chain reaction (PCR) analyses demonstrated that 41 strains were identified as S. Typhimurium (39 strains), though 2 stains were failed to identify. Further identification was performed using both direct smear and protein extraction method by MALDI-TOF MS analyses. In terms of extraction methods, 100% (41/41) of isolates were identified to species level of S. spp. Whereas only 43.9% (18/41) were identified to species level using the direct method. These results thus suggest that rapid and accurate diagnosis of porcine salmonellosis can be guaranteed by MALDI-TOF MS combined with protein extraction method.

It is very important to provide a parameterized quality of service (QoS) using traffic specification (TSPEC), such as mean data rate, maximum burst size, and peak data rate, when packets from the application layer need to be transmitted with guaranteed services in a high-rate wireless personal area network (HR-WPAN). As medium resources are limited, the optimal medium time required for each device needs to be estimated to share the resources efficiently among devices. This paper proposes a variable-service interval-based resource allocation algorithm to efficiently make a reservation of medium resources based on a parameterized QoS. In other words, the proposed algorithm calculates the number of medium access slots (MASs) based on TSPEC, local resources, and local conditions and determines suitable locations for the MASs within a superframe to accommodate more devices. The simulation results show that the proposed algorithm can accommodate more devices and has greater than 10% resource allocation efficiency in an HR-WPAN compared to existing schemes.

Acanthomatous epulis is a malignant form of gingival tumor. This is a case of epulis affecting a four-year old, intact, female Maltese dog raised as indoor pet in Iksan city. Clinical examination showed an enlarged palpable mass along the rostral maxillary gingiva. Section of the excised mass showed epithelial overgrowth and expansion from the basal portions through the tissue stroma. Post-surgical radio-graph showed displacement of the first and second maxillary incisors. Histochemical staining showed strongly positive reaction to epithelial marker cytokeratin and moderately positive reaction to connective tissue marker vimentin. This case was diagnosed as a form of maxillary gingival acanthomatous epulis. Routine clinical oral examination is suggested.

Software and Systems Product Line(SSPL) is a paradigm that has been developed and applied by European Union(EU) to achieve the productivity and competitiveness of EU industries on the world market. It is not just a simple system or software development methodology, but a sophisticated technology requiring capabilities for a high level of mass customization, platforms, processes and convergence of software and systems. EU has applied SSPL for the five selected industrial sectors including aerospace, automobile, medical equipment, consumer electronics and telecommunication equipment since 1990s and led the way to other industry sectors to stimulate the application of SSPL from 2006. In order for Korea to secure competitiveness in the manufacturing and service industries in the competitive borderless market, it is essential to gain the high level of capabilities for software development and convergence of software and systems. SSPL can be a powerful means to achieve this end. This paper discusses the paradigmatic concept of SSPL, how EU's major industries and companies have secured competitiveness through SSPL, key capabilities that are necessary for successful institutionalization of SSPL in Korea, and finally suggestions on core strategies to materialize the benefits of SSPL for Korea.

In May 2007, mass mortality of Israeli carp, Cyprinus carpio L., was occured on a pond farm located in Jeollabukdo Province, Korea. The mortality rates reached up to 2% of the total fish in the farm per day. Typical clinical signs were abdominal distension, reddish foci on the skin, enteritis, liver congestion and enlarged spleen and kidney. On the basis of biochemical characteristics and 16S rDNA sequence, the causative bacteria isolated from affected carp were identified as Aeromonas veronii. Histologically, degeneration of hepatocytes and congestion in sinusoids were observed in the liver. Spleen showed hemorrhage and the destruction of the sheathed tissues. In kidney, necrotized renal tubules and glomerular destructions were observed. Intestinal tissues revealed necrotized and severe hemorrhage. Mass hemorrhage was observed in muscles. This is the first report that A. veronii caused mortality in cultured Israeli carp in Korea.

화점높이 변화에 따른 풀 화재의 연소특성을 알아보기 위하여 인화성액체인 메탄올과 노르말 헵탄을 $100mm{\times}100mm{\times}50mm$ 크기의 사각형 용기에 내에 넣고 연소실험을 하였다. 용기의 재질은 스테인레스를 사용하였다. 연소시간, 질량감소속도, 화염온도, 화염높이 및 외부에서 화염으로의 공기유입속도 등을 측정하였으며 연소시 화염의 거동은 비디오카메라를 이용하여 촬영하였다. 실험을 통해서 화점의 높이가 증가할수록 외부에서 화염으로 유입되는 차가운 공기의 유입량이 증가하여 풀 화재의 연소특성이 감소함을 확인 할 수 있었다.

최근 인터넷 방송이나 VOD와 같은 대용량 데이터 서비스에 대한 이용이 보편화되면서 네트？의 트래픽이 급증하고 있다. 이에 따라 발생하는 서비스의 지연문제를 해결하기 위해 대역폭의 확장뿐 아니라 망의 확장성을 해결할 수 있는 방안들이 모색되고 있다. 이러한 방안의 하나로서 MPLS는 망의 확장성과 고속의 라우팅을 지원하는 장점이 있으나 모든 패킷은 입구 노드에서 출구 노드까지 LSP가 설정 되기 전까지 지연이 발생한다. 본 논문에서는 이러한 지연 문제를 해결하기 위해 데이터가 MPLS 도메인을 거쳐 가야 할 경우 입구노드에서 출구 노드까지의 홉수에 따라 서로 다른 레이블 할당 기법을 사용하는 방안을 제안한다. 또한 제안된 방안을 사용했을 경우 어느 정도의 지연 감소를 얻을 수 있는지를 보였다.

Objectives: The purpose of this study was to discuss the overall and oral health conditions that affect obesity in middle-aged women in Jeju and to help them operate the effective obesity program in the future. Methods: Participants of this study were 171 middle-aged women living in Seogwipo City, Jeju Special Self - Governing Province. Data were collected through the convenience sampling method. Body mass index and waist circumference of each participant were measured, and a self-report questionnaire was applied. Results: The overall health status of obesity comprised depression, stress, diabetes, and menopause. The oral health conditions affecting obesity were bad breath and chewing. Hypertension was the main factor affecting body mass index and depression was the main factor influencing waist circumference. Obesity was more influenced by overall health status factors than by oral health status factors. Conclusions: The results of this study are expected to be useful as basic data for efficient health care services in the prevention of obesity.

Telematics, one of the so-called New Growth Engine of IT839, is a leading IT service where wireless internet service represented by information and mobility is extended to the area of transportations to provide Telematics service. The killer-application of Telematics is navigation system. Recently, due to the mass storage conversion, the performance of the terminal and mobile communications technology development, navigation system is also changed. It more and more develops into 3D in a preexistence 2D map. In the future, it is expected to include the remote sensing map. There is also the characteristic of all the information expressed in frequently a change partially happening. That is, POI(Point Of Interest) which is freshly registered or is deleted is many. In a preexistence, MCP(Map Contents Providers) offer the new version map by off-line monthly or quarterly. And a user wastes time and is inconvenient because of updating the total map by the off-line. Thus, in this paper, in order to resolve this, we describe MCP-MAUS(Maus Air Update Server) interface for updating only the partial map that was changed.

We reported that high dielectric hafnium oxide nano-film deposited by thermal atomic layer deposition on the poly-silicon film (poly-Si). The poly -Si film was produced by plasma enhanced chemical vapor deposition and excimer laser annealing. We used the hafniu m chloride ($HfCl_4$) and water as the precursors and analyzed the hafnium oxide film by transmission electron microscope and secondary ion mass spectrometer. Hafnium oxide produced by the ALD method showed very good coverage on the rough surface of poly-Si film. While deposited with 200 cycles, these hafnium oxide films revealed a relatively smooth surface and good uniformity, but the cumulative roughness produced by the incomplete reaction was apparent when the amount of deposition cycle increased to 600 cycles.
