Game was begun to sell to multi platform rather than is sold as a title of a kinds of machine since some moment. In case of competition flag species such as PS (Play Station) or XBOX, there is 'Final Fantasy', 'Gear of War' masterpiece. However, title of game was begun to manufacture to multi platform and this is step that much games are manufactured to multi platform by selection of game developers to minimize danger by production cost rise of game. About game character development method in multi platform surrounding that this research is such game character abstract of multi platform and multi platform environment direction for multi platform through analysis and example proposal to basis data for presentation utilize wish to.

The distributed object computing is possible to distributed computing on same or heterogeneous machine environment with growth of distributed computing and object-oriented technology. The typical of model, CORBA is int solved the interoperability in heterogeneous machine environment over the network But, the CORBA has a problem that the server is can't rely on request of client occurs network overhead by extinction of network A plan was on the rise to solve the problem that is combination of mobile agent and distributed computing technology.

기업의 물류활동은 화물의 기종점 정보와 더불어 출발지와 도착지간 수배송특성, 업종간 거래 관계, 가격흐름, 경로 등 다양한 공급사슬관점에서 설명되어야 한다. 본 연구는 화물의 흐름을 물적인 흐름의 공급사슬망인 유통경로 관점에서 실증분석을 목적으로 한다. 그동안 공공부문의 물류관련 연구들은 물류현황조사 자료로부터 지역간 기종점 통행량에 기초하여 물류시설을 포함한 국가의 사회간접자본 투자정책에 주로 활용된 경향이 있었다. 또한, 민간부문의 유통경로 관련 연구는 주로 상적인 유통경로에 한정되어 보다 종합적인 공급사슬관리 측면에서 기업의 물적 유통경로선택에 대한 이해가 부족하였다. 본 연구에서는 2001년 전국물류현황조사중 기업의 물류실태조사에서 수행된 600개의 표본자료에 기초하여 기업들의 유통경로 선택의 특성을 분석하였다. 사용된 자료들의 설문조사방식은 다양한 유통노드들이 제시되고, 기업들이 상위 매출액이 높은 품목들이 다양한 유통경로 상에서 어떻게 노드들을 이용하는지 조사되었고, 이를 공장순회형, 물류센터 중심형, 도매자 중심형, 소비자 중심형 등 4개로 유형화하였다. 본 연구는 이들 4개의 유통경로들의 선택에 미치는 영향을 사업체 현황, 수배송현황, 물류활동평가, 물류시설관리 현황 등의 다양한 특성변수를 고려하여 선택에 미치는 영향을 분석하였다.

Background : Spontaneous pneumopericardium is a very rare condition. Spontaneous pneumothorax and pneumomediastinum have been reported to be associated with an idiopathic pulmonary fibrosis (IPF). However, spontaneous pneumopericardium has not yet been reported in association with IPF. Here we report a case of spontaneous pneumomediastinum and pneumopericardium in a patient with acute exacerbation of IPF with a review of the relevant literature.

Emphysematous pyelonephritis is a necrotizing renal infections characterized by intrarenal and occasional perirenal gas production. Although uncommon (89 cases in the literature), it occurs almost exclusively in diabetic patients (87% of the cases). Prompt and aggressive management is required to salvage these patients. We describe a recent case of a diabetic woman with emphysematous pyelonephritis due to E. Coli, successfully managed with unilateral nephrectomy.

As network security is coming up with significant problem after the major Internet sites were hacked nowadays, IDS (Intrusion Detection System) is considered as a next generation security solution for more trusted network and system security We propose the new IDS model which can detect intrusion in the expanded distribute environment in host level, drawback of existing IDS, and implement prototype. We used pattern extraction agent so that we extract automatically audit file needed in intrusion detection even in other Platforms.

네이티브 앱은 디바이스에 설치하여 직접 실행하는 타입으로 속도가 빠르고 좋은 성능을 보인다. 그러나 네이티브 앱은 특정 스마트폰 OS에 종속되어 실행되므로 서로 다른 이 기종 OS에서 실행되기 위해서는 추가 개발 비용이 발생한다. 이를 해결하기 위해 모바일 웹의 개발이 증가하고 있지만 모바일 웹의 사용자 인터페이스를 네이티브 앱과 동일하게 구성하기 쉽지 않은 단점이 있다. 본 논문은 이 기종 스마트폰 환경에서 앞서 언급한 문제점을 해결하기 위해 cocos2D를 활용한 모바일 웹 설계 및 구현 결과를 제안한다. 제안된 모바일 웹은 기존 모바일 앱의 사용자 인터페이스와 유사하게 구성하여 이질감을 없애고 OS에 상관없이 동일하게 실행된다. cocos2D 게임엔진을 활용하여 사용자 인터페이스를 설계하였다. 이것을 모바일 웹으로 구성하기 위해 JAVA Script에 내장하여 HTML5로 구현하였다. 구현결과는 현재 사용되고 있는 스마트폰 OS 및 여러 디바이스에서 검증하였으며 높은 가동률을 보였다. 논문에서 제안된 기술을 활용할 경우 개발자는 개발에 소요되는 비용을 줄일 수 있을 것으로 예상되며 사용자의 경우 디바이스의 제약 없이 모바일 어플리케이션을 사용할 수 있을 것이다.

The initial market of alternative-fuel vehicle (AFV) will show geographically uneven distribution due to AFV's high price, and thus efficient location model should consider spatial variation of demand. This paper estimates AFV trips by incorporating an AFV demand estimation model with origin-destination (OD) trips. The estimates are the input for the flow-refueling location model that maximizes the OD flows that can be refueled by the given number of stations considering AFV's limited range per refueling. A scenario analysis is conducted by varying assumptions in estimating demands and AFV acceptance rate. Optimal location alternatives for Orland metropolitan area are provided and results are compared.

An efficient PCB assembly method with Gantry type machine is developed and proposed in this paper to improve system productivity. Nozzle changes at Gantry type machine is the major reason causing lower system performance instead of header and slot movements on the other type machines. The problem is attacked by maximizing multiple adsorptions to reduce the number of necessary nozzle changes with Gantry type machine. It is designed to reduce the assembly time per PCB with multiple adsorptions based upon the positions of feeders and nozzles. A simulation model is constructed to show the effectiveness of the suggested heuristic and necessarily a comparison study is followed with different methods on selection of next assembly feeder and nozzle with various cases.

The Weolchulsan is one of the phytogeographically important areas among national parks of Korea because this region is located in the northern limit of Southern Plant Types. The flora of the area was enlisted as 516 taxa, 106 families, 318 genera, 453 species, 59 varieties, and 4 forms. The six taxa such as Diplomorpha trichotoma, Monotropastrum globosum, Hololeion maximowiczii, Drosera rotundifolia, Utricularia japonica and Utricularia racemosa are enlisted as the Rare and Endangered Species which is categorized by the Korea Forest Service. The Ratio of Naturalized and Urbanization Index was 4.65% and 9.06%, respectively.
