The present paper proposes a novel dynamic system for hand gesture recognition. The approach involved is comprised of three main steps: detection, tracking and recognition. First, the gesture contour captured by a 2D-camera is detected by combining the three-frame difference method and skin-color elliptic boundary model. Then, the trajectory of the hand gesture is extracted via a gesture-tracking algorithm based on an occlusion-direction oriented linear extrapolation predictor, where the gesture coordinate in next frame is predicted by the judgment of current occlusion direction. Finally, to overcome the interference of insignificant trajectory segments, the longest common subsequence (LCS) is employed with the aid of velocity information. Besides, to tackle the subgesture problem, i.e., some gestures may also be a part of others, the most probable gesture category is identified through comparison of the relative LCS length of each gesture, i.e., the proportion between the LCS length and the total length of each template, rather than the length of LCS for each gesture. The gesture dataset for system performance test contains digits ranged from 0 to 9, and experimental results demonstrate the robustness and effectiveness of the proposed approach.

This article considers Chunhyanjeon written in Japanese by Jang Hyukju in 1938. His Chunhyangjeon was presented from among the collusion and crack of 'things Japanese' and 'things Chosun' discussed in Japanese literary world in the 1930's. This article analyzed the writing method and the meaning of the text. Jang Hyukju(張赫宙, 1905~1997) became known to Japanese literary world by the second grade nomination of the prize contest of the magazine Kaizo in 1932. Since then, he worked actively in the Japanese literary world by writing novels in Japanese and introducing the literature of Chosun. Thanks to his activity, the literature of Chosun drew attraction from the Japanese, which can be called 'boom'. Jang Hyukju was in the middle of this boom. So, his text presented the collusion and crack of empire and colony. We can make sure this issue from his play Chunhyangjeon. When he presented Chunhyangjeon, Jang Hyukju mentioned his purpose of writing. He intended to write modern play in new literary style. Chunhyangjeon was surely the material of things traditional Chosun, which was corresponded to the demand of Japanese literary world. Through the story of Chunhyangjeon, however, he formed the modern text style. He wrote in standard Japanese language, and described things from the perspective style which is often used in modern novel. And he renewed the character characteristically and arranged the structure of the play. His writing style showed clear distinction in the comparison to Chunhyangjeon written by You Chijin which was presented in Korean language 2 years earlier than Jang Hyukuju's. The text Chunhyangjeon written in Japanese by Jang Hyukju reflected specificity as a district of Japan. But on the other hand, a new literary method of modern realism was tried. Chunhyangjeon written by Jang Hyukju shows the cross penetration of empire and colony. And in his Japanese-language literature, the literature of Chosun is coexisting and playing variation.

한국역사에서 일제강점기에 대한 당위적 결론은 종종 역사적 상상력을 압도하는 경우가 많았는데, <경성탐정이상>도 근대역사학의 한계를 지적하면서 등장한 역사추리소설장르임에도 비슷한 양상을 보여준다고 지적되고 있다. <경성탐정이상>에 등장하는 역사적 사실, 민족주의에 기반 한 독립의 당위성, 근대문명 등은 일제강점기 역사문화 콘텐츠에서 눈에 익은 구도이다. 이는 '상상의 공동체(민족)'에 대한 대중의 현재적 욕망을 현재로서의 역사, 현재의 사회적 갈등이 투사된 역사로 역사문화콘텐츠에 반영하기 때문이다. 역사를 다룬 콘텐츠들에서 역사, 역사적 사실, 허구는 뒤섞여지며 새로운 '역사적 상상'을 만들어 낸다. 실재로서 과거의 사실은 하나지만, 역사가가 만드는 역사적 사실은 하나가 아니라 여럿이듯이 역사문화콘텐츠의 역사적 상상은 다양하다. 아직까지 역사학은 미래를 위한 상상력으로까지 나가고 있지 못하지만, 역사문화콘텐츠를 통한 역사쓰기는 '가능성의 역사'를 만들어낼 수 있을 것이다.

At present, the world is witnessing a rapid change in all the fields of human civilization business interests and goals of all the sectors are changing very fast. Global changes are taking place quickly in all fields - manufacturing, service, agriculture, and external sectors. There are plenty of hurdles in the emerging technologies in agriculture in the modern days. While adopting such technologies as transparency and trust issues among stakeholders, there arises a pressurized necessity on food suppliers because it has to create sustainable systems not only addressing demand-supply disparities but also ensuring food authenticity. Recent studies have attempted to explore the potential of technologies like blockchain and practices for smart and sustainable agriculture. Besides, this well-researched work investigates how a scientific cum technological blockchain architecture addresses supply chain challenges in Precision Agriculture to take up challenges related to transparency traceability, and security. A robust registration phase, efficient authentication mechanisms, and optimized data management strategies are the key components of the proposed architecture. Through secured key exchange mechanisms and encryption techniques, client's identities are verified with inevitable complexity. The confluence of IoT and blockchain technologies that set up modern farms amplify control within supply chain networks. The practical manifestation of the researchers' novel blockchain architecture that has been executed on the Hyperledger network, exposes a clear validation using corroboration of concept. Through exhaustive experimental analyses that encompass, transaction confirmation time and scalability metrics, the proposed architecture not only demonstrates efficiency but also underscores its usability to meet the demands of contemporary Precision Agriculture systems. However, the scholarly paper based upon a comprehensive overview resolves a solution as a fruitful and impactful contribution to blockchain applications in agriculture supply chains.

This article set out to develop an old Chinese - modern Korean collated terminology by analyzing and paralleling Chinese-Korean translational terms relevant to Korean medicine at a minimum meaning unit from "Eonhaegugeupbang", "Eonhaetaesanjipyo" and "Eonhaetaesanjipyo". Those are composed of original Chinese texts and their subsequent corresponding Korean translations. It tries to make a list of translational standards of Korean medicine terms by classifying the cases of translational ambiguity in terms of disease, body position, thumbnail-pressing acupuncture method, and disease-curing method. The above-mentioned ancient books are medical classics written by Huh Jun, the representative medical physician, and published by the Joseon government. Thus, they are appropriate enough as historically legitimate medical documents, from which are drawn out words and terms to form an old Chinese - modern Korean collation dictionary. This collation glossary will contribute to the increased relevance of data ming, or information retrieval. in a database system and information search engine of massive Korean medical records, by means of providing a novel way to obtaining synchronized results between the original writings of old Chinese and the secondary translated ones of modern Korean. The glossary will promote the collective but consistent translation of numerous old archives of Korean medicine and in other related fields as well.

Via the Internet, the information infrastructure of modern health care has already established medical information systems to share electronic health records among patients and health care providers. Data hiding plays an important role to protect medical images. Because modern medical devices have improved, high resolutions of medical images are provided to detect early diseases. The high quality medical images are used to recognize complicated anatomical structures such as soft tissues, muscles, and internal organs to support diagnosis of diseases. For instance, 16-bit depth medical images will provide 65,536 discrete levels to show more details of anatomical structures. In general, the feature of low utilization rate of intensity in 16-bit depth will be utilized to handle overflow/underflow problem. Nowadays, most of data hiding algorithms are still experimenting on 8-bit depth medical images. We proposed a novel reversible data hiding scheme testing on 16-bit depth CT and MRI medical image. And the peak point and zero point of a histogram are applied to embed secret message k bits without salt-and-pepper.

Field epidemiology involves the implementation of quick and targeted public health interventions with the aid of epidemiological methods. In this article, we share our practical experiences in outbreak management and in safeguarding the population against novel diseases. Given that cities represent the financial nexuses of the global economy, global health security necessitates the safeguard of cities against epidemic diseases. Singapore's public health landscape has undergone a systemic and irreversible shift with global connectivity, rapid urbanization, ecological change, increased affluence, as well as shifting demographic patterns over the past two decades. Concomitantly, the threat of epidemics, ranging from severe acute respiratory syndrome and influenza A (H1N1) to the resurgence of vector-borne diseases as well as the rise of modern lifestyle-related outbreaks, have worsened difficulties in safeguarding public health amidst much elusiveness and unpredictability. One critical factor that has helped the country overcome these innate and man-made public health vulnerabilities is the development of a resilient field epidemiology service, which includes our enhancement of surveillance and response capacities for outbreak management, and investment in public health leadership. We offer herein the Singapore story as a case study in meeting the challenges of disease control in our modern built environment.

In this modern era of technology and information, e-learning approach has become an integral part of teaching and learning using modern technologies. There are different variations or classification of e-learning approaches. One of notable approaches is Personal Learning Environment (PLE). In a PLE system, the contents are presented to the user in a personalized manner (according to the user's needs and wants). The problem arises when a new user enters the system, and due to the lack of information about the new user's needs and wants, the system fails to recommend him/her the personalized e-learning contents accurately. This phenomenon is known as cold-start problem. In order to address this issue, existing researches propose different approaches for recommendation such as preference profile, user ratings and tagging recommendations. In this research paper, the implementation of a novel interaction-based approach is presented. The interaction-based approach improves the recommendation accuracy for the new-user cold-start problem by integrating preferences profile and tagging recommendation and utilizing the interaction among users and system. This research work takes leverage of the interaction of a new user with the PLE system and generates recommendation for the new user, both implicitly and explicitly, thus solving new-user cold-start problem. The result shows the improvement of 31.57% in Precision, 18.29% in Recall and 8.8% in F1-measure.
