Evaluating current situation in the East Asia, the foremost issue of concern is the Rising China and China"s leadership. The signs of Cheonan incident, Yeonpyeongdo crisis and East Japan crisis are over clouding the regional security. When the East Asia nations around the region perceive security recess, the region eyes on China, the first largest economy experiencing sustainable economic growth and holds the highest foreign exchange reserve in the world and the rising superpower took the leading role in the economic recovery. As such, the region eyes on China to see whether the country will step up and take the leading role as it did in 2008 if another such crisis occurs in 2011. But China must have been considered one’s political calculation in those critical moments. With that, what are China"s concerns and how would its leaders respond to the current East Asia situation? On a primary level, China is interested in its dollar assets and a slowdown in exports, also weaken their military power. China’s rapid economic growth and military modernization had changed East Asia’s power relations, challenging the predominant position of the U.S. and its role as regional balancer. However, China must have been know its own limitations by Cheonan incident, Yeonpyeongdo crisis and East Japan crisis.

텍스트 신뢰도 자질 기반 지식 질의응답 문서 품질 평가 모델

불특정 다수 사용자가 정보를 생성하는 지식 질의응답 서비스에서는 문서의 품질이 검색결과 만족도에 중요한 요소 중 하나이다. 지식 질의응답 문서의 품질 평가에 관한 기존 연구는 조회 수와 추천수 등의 비텍스트 정보를 이용하여 문서의 품질을 평가하고, 이를 검색 모형에 반영하여 검색 성능을 높이는데 집중하였다. 이러한 비텍스트 정보는 그 유용성이 실험을 통해 증명되었다. 그러나 비텍스트 정보를 이용하여 새로 작성된 문서의 품질을 평가할 경우 심각한 자료 부족 문제가 발생할 수 있다는 단점이 있다. 본 논문에서는 이러한 비텍스트 정보의 자료 부족 문제를 완화할 수 있는 새로운 문서 품질 평가 자질로서 문서 내용 자체에 대한 신뢰성을 반영하는 신뢰도 자질을 제안한다. 제안하는 자질은 문서의 내용으로부터 직접 추출되며, 따라서 추천 수나 조회 수 등 서비스 사용자의 참여를 간접적으로 필요로 하는 비텍스트 자질보다 자료 부족 문제에 견고하다는 장점이 있다. 또한 제안하는 신뢰도 자질은 문서 품질 평가에 유용하다고 알려진 비텍스트 자질과 유사하거나 향상된 성능을 실제 지식 질의응답 문서를 대상으로 한 실험에서 보였으며, 추후 효과적인 품질 평가 자질로서 지식 질의응답 서비스의 성능향상에 기여를 할 수 있을 것으로 기대된다. In Knowledge Q&A services where information is created by unspecified users, document quality is an important factor of user satisfaction with search results. Previous work on quality prediction of Knowledge Q&A documents evaluate the quality of documents by using non-textual information, such as click counts and recommendation counts, and focus on enhancing retrieval performance by incorporating the quality measure into retrieval model. Although the non-textual information used in previous work was proven to be useful by experiments, data sparseness problem may occur when predicting the quality of newly created documents with such information. To solve data sparseness problem of non-textual features, this paper proposes new features for document quality prediction, namely text-confidence features, which indicate how trustworthy the content of a document is. The proposed features, extracted directly from the document content, are stable against data sparseness problem, compared to non-textual features that indirectly require participation of service users in order to be collected. Experiments conducted on real world Knowledge Q&A documents suggests that text-confidence features show performance comparable to the non-textual features. We believe the proposed features can be utilized as effective features for document quality prediction and improve the performance of Knowledge Q&A services in the future.

This essay will observe the status, condition, and participation of military-supported defense exhibitions hosted in the domestic area, with the purpose of invigorating defense export through hosting effective defense exhibitions by identifying areas of improvement and guaranteeing most efficient support measures. Defense exhibitions presently supported by the military are Aerospace & Defense Exhibition (hereinafter, ADEX), Naval & Defense and DX Korea. Given the distinct characteristics on defense industry and expertise, these defense exhibitions were hosted with active support from the military in various areas such as exhibiting military equipment and forces, inviting key military personnel from abroad, providing performance by the military band and honor guard, and demonstrating special force martial arts. Despite the advancement on defense exhibition via continued growth in the international defense industry and increase in export opportunities for domestic defense companies, the military`s support system for exhibition has thus far stalled and calls for improvements. In conclusion, in order to strengthen domestic defense industry and to develop current exhibitions which significantly contribute to defense export at an international level, it is essential to devise a comprehensive defense export plan at national level and to establish a systematic and efficient support system by the government and military agencies, as well as to further promote specific land equipment exhibition to encourage a balance development in land, maritime, and aerospace defense exhibitions.

대전지역 건물음영을 고려한 PV 최적각도 산정

By blocking irradiance, shadows cast by high-rise buildings in urban areas can reduce the power generation efficiency of PV panels installed on low-rise buildings. As the conventionally installed PV panel is not suitable for the urban environment, which is unfavorable for power generating, a more radical solution is required. This study aims to help solve this problem by estimating the optimal PV panel angle. Using the proposed method, the optimal PV angle was calculated by considering shadows that could be cast by nearby buildings throughout the year, and the correlation between solar shading and elevation angle was discovered based on the calculated data.

Objective & Methods: The purpose of this study is to investigate the effects of Artemisiae Capillaris Herba herbal-acupuncture (ACH-HA) at GB34 (Yangleungchean) on hyperlipidemia induced with alloxan injection and high fat diet in rats. The author performed several experimental items to analyze the levels of various components and enzymes in serum, liver, as well as the histological changes of liver and aorta. Results: 1. ACH-HA solution increased the DPPH radical scavenging activity in rat liver cells. 2. ACH-HA at GB34 significantly decreased the levels of serum total cholesterol, low-density lipoprotein (LDL)-cholesterol, free cholesterol and atherogenic index (AI), while significantly increased the ratios of high-density lipoprotein (HDL)/total cholesterol and phospholipid/total cholesterol in hyperlipidemic rats. 3. ACH-HA at GB34 significantly decreased serum aspartate aminotransferase (AST) level in hyperlipidemic rats. 4. ACH-HA at GB34 significantly increased hepatic glutathione (GSH) activity in hyperlipidemic rats. Conclusion: From the above results, it is suggested that ACH-HA at GB34 may have therapeutic and preventive effects on hyperlipidemia.

RFID 애플리케이션을 위한 분산 이벤트 처리 모델

이정태(Jung-Tae Lee),김명욱(Myung-Uk Kim),류기열(Ki-Yeol Ryu) 한국정보과학회 2004 한국정보과학회 학술발표논문집 Vol.31 No.1A

유비쿼터스 환경의 RFID 애플리케이션을 위해 RFID 태그에서 발생하는 베이직 이벤트와 복합 이벤트인 시맨틱 이벤트의 두 가지로 이벤트를 분류하고 이중화된 구조의 분산 이벤트 네트웍 아키텍쳐 모델을 제안한다. 이중화된 구조는 각각 베이직 이벤트의 전달을 위한 아래쪽 이벤트망, 시맨틱 이벤트의 전달을 위한 위쪽 이벤트망으로 구성된다. 제안한 모델은 이벤트 통지 서비스와 메시징 서비스를 응용한 이벤트 등록 및 전달 구조를 사용하여 작업 부하를 애플리케이션에서 미들웨어로 이전함으로써 전체 작업의 양을 감소시킬 수 있고 시맨틱 이벤트를 사용함으로써 미들웨어-애플리케이션 통신량을 줄일 수 있다.
