In this paper, we present a design and implementation of a TV-Anytime compliant STB to provide personalized content consumption according to user preferences and various terminal/network conditions. This paper mainly details with a metadata engine which consists of meta data de-multiplexing, metadata decoding, and metadata-based content browsing. For personalized content consumption, the proposed metadata engine provides the following key functionalities: advanced EPG, non-linear segment navigation wirh Tables-of-Content and/or event-based summary, automatic recommendation of user-preferred programs, and etc. The implemented STB employing the metadata engine is successfully tested with a set of service scenarios in an end-to-end broadcasting test-bed.

In this paper, an efficient algorithm is proposed which recognizes the mixed document consisting of the printed Korean/alphanumeric texts and graphic images. In the preprocessing step an input document is aligned if necessary by rotating it. We obtain the rotation angle using the Hough transform and align the input document horizontally. Then we separate graphic image parts from text parts by considering chain codes of connected components. We further separate each character using vertical and horizontal projections. In the recognition step Korean and alphanumeric characters are classified and each of them is recognized hierarchically using several features. In summary an efficient recognition algorithm for mixed documents is proposed and its performance is demonstrated via computer simulations.

The Statistic-based method is widely used for automatic single document summarization in large sets of documents such as those on the web. However, the results of this method shows high redundancies in the summarized sentences because this method selects sentences including words that frequently appear in the document. We solve this problem using the method MMR to raise the quality of document summary (The best results are appeared around λ=0.6). Also, we compare the MMR summaries with those done by human subjects and verify their accuracy.

Objective: Egg consumption has been suggested to increase the risk of colorectal and some other cancers. The present study summarized and quantified the current evidence relating dietary intake of eggs and prostate cancer. Materials and methods: Literature searches were conducted to identify peer-reviewed manuscripts published up to July 2012. Twenty manuscripts from nine cohort studies and 11 case-control studies were identified. Summary risk estimates with 95% confidence intervals (CIs) were calculated for case-control and cohort studies separately. Results: Neither the case-control not the cohort studies showed any association of prostate cancer incidence with egg consumption (case-control studies: odds ratio 1.09, 95% CI 0.86-1.31; cohort studies: relative risk 0.97, 95% CI 0.97-1.07). The results were consistent in subgroup analysis. Furthermore, no association was observed between egg consumption and prostate cancer-specific mortality. Conclusions: Our analyses provided no evidence of a significant influence of egg consumption on prostate cancer incidence and mortality. However, more studies, particularly large prospective studies, are needed.

Assistance for the quality assurance management and developers to provide high quality software products. Using a bug record keeping system is exceptionally important in software progress, and it is followed vastly by majority of software producing companies in modern era. Regular application of a bug record keeping system is very helpful in developing software systems. We developed this system which helps the software testing team to keep a complete record of their testing activities during the software testing, also increases your confidence in the software quality, class and worth. Our proposed system offers trouble-free and effortless approaches to acquire desired information about bug, also produces different kinds of reports like summary reports, detailed reports etc. It gives facility to create, delete and update any project. Our developed application system is designed by using visual c# at front end and sql server 2008 management studio express at back end.

본 논문에서는 국가 연구 보고서의 공기 관계 정보와 제목, 요약 등에 가중치를 적용한 유사도 계산방법을 제안한다. 이를 위해 국가 연구개발 보고서에서 텍스트를 추출하여 한 문장 단위로 문서를 분할하고, 기본 불용어와 보고서에서 특징적으로 나타나는 불용어를 처리하고 형태소 분석을 한 뒤 공기관계를 추출하였다. 또한 문서의 유사도 계산시 정확성을 높이기 위해 제목과 요약 부분에 가중치를 부여하였다. 이를 통해 본 논문에서 제안하는 방법이 문서 검색 라이브러인 루씬(Lucene)을 이용한 방법보다 2.5%의 검색성능 향상을 그리고 Knn-휴리스틱 방법보다는 1.1%의 검색성능 향상을 보였다. 이러한 결과를 통해 문서의 요약과 제목 그리고 공기관계 정보가 연구보고서의 유사도를 계산 하는데 영향을 미친다는 것을 보였다.

The new version of Code for Design of Steel Structures (GB50017-2003) and other design standards in China were released over the last two years. Comparing with the previous version (GBJ17-88), many clauses covering the connection design have been revised. A number of additional provisions are supplemented to specify the design requirements for beam-column moment connections, as well as gusset plates for truss joints. In this paper, a summary on the design rules on connections specified in the current Chinese code is presented, and relevant commentary and background information is provided whenever appropriate. The design criteria governing weld and bolt resistance is examined and reviewed. Moreover, several issues such as detailing requirements for stiffeners and end-plate connections are discussed.

Tactile sensors, which are commonly referred to as pressure and strain sensors, have been extensively investigated to meet the demands for attachable and wearable electronics for monitoring the health status or activity of human users. For this purpose, the introduction of two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs) with high mechanical strength at the atomic scale is very suitable for tactile sensors applicable for use in human-friendly devices. In this paper, we examine a descriptive summary of a tactile sensor and review state-of- the-art research trends of 2D material-based tactile sensors in terms of the material and architecture. Finally, we propose a roadmap for future studies into advanced tactile sensors based on our ongoing research.

The overall purpose of this paper is to conduct research on alternatives for strengthening the competitiveness of a state-run shipping company, Vinalines Corporation, the largest shipping and maritime enterprise in Vietnam. The first section of the introduction gives a panoramic overview of the current development situation of the Vietnam maritime industry and Vinalines. After summarizing a literature review in section 2, some alternatives are proposed in sections 3 and 4 to overcome the current difficulties of Vinalines and to improve the corporation's competitiveness for sustainable development by utilizing linear optimization and financial analysis. The final section presents a summary and recommendation for future study. It is concluded that privatization is the key solution for every problem faced by the corporation at present. Furthermore, modification of laws, restructuring of enterprise governance, financial situation, and fleet are also extremely necessary.

In this paper, we propose a novel block cipher mode of operation, which is known as the counter chain (CC) mode. The proposed CC mode integrates the cipher block chaining (CBC) block cipher mode of operation with the counter (CTR) mode in a consistent fashion. In the CC mode, the confidentiality and authenticity of data are assured by the CBC mode, while speed is achieved through the CTR mode. The proposed mode of operation overcomes the parallelization deficiency of the CBC mode and the chaining dependency of the counter mode. Experimental results indicate that the proposed CC mode achieves the encryption speed of the CTR mode, which is exceptionally faster than the encryption speed of the CBC mode. Moreover, our proposed CC mode provides better security over the CBC mode. In summary, the proposed CC block cipher mode of operation takes the advantages of both the Counter mode and the CBC mode, while avoiding their shortcomings.
