In ad hoc networks, a distributed timing synchronization is studied using a firefly-inspired approach. We illuminate the exiting synchronization algorithm based on the theory of pulse-coupled oscillators so that the algorithm can be applied to multi-carrier systems through packet-based communications, where nodes communicate over an orthogonal frequency-division multiple access air interface. As our main result, we introduce a new sync-code detector, which optimally designs both the coupling function and the detection threshold when various network parameters such as the number of nodes in the network and network topology are given a priori. Computer simulations are performed to show the convergence to a synchronized state in realistic network environments.

Popular culture has symbolic meaning and has been constructed through different mass media. Newspapers played a significant role in 1950s and 1960s public culture. In particular, editorial cartoons in newspapers expressed social aspects of the age implicitly through satire and criticism. This study examines delivered culture by reflecting the past social aspects and inquiring on clothing featured in the editorial cartoon "Gobau". As for a research method, literature research was conducted on clothing of the age with a review of "Gobau". As for a research range, examination was done based on the complete works of Gobau composed of 5 volumes published as a first edition by Hankookmunhwasa on November, 1973. Early "Gobau" cartoons from 1951-1963 were published in 5 volumes; therefore, research was conducted for the era from 1950s to the early 1960s. Clothing expressed in "Gobau" were reviewed, classified into formative characteristics and internal meaning. Internal meaning was examined by dividing into the expression of social aspects and criticism of society. The research findings are as follows. First, clothing in "Gobau" reflected characteristic in direct manner. There was a coexistence of Hanbok and western-styled, clear distinction between men's trousers and women's skirt. Besides, various kinds of women's western-styled dress appeared in the 1960s. Second, they showed the dress culture that reflected past social aspects. Many aspects were included to reconstruct old and worn clothes due to scarce resources after the Korean War, and cherishing clothes, buying fabric directly to making clothes, making clothes from dressmaking shop, and restrictions on imported goods and luxury items. Third, the study also examined the social norms for fashion. It contained negative perspectives on women wearing pants, short skirts, and new hair styles (like perms) from western culture as well as lipstick.

Biologically inspired modeling techniques have received considerable attention for their robustness, scalability, and adaptability with simple local interactions and limited information. Among these modeling techniques, Gene Regulatory Networks (GRNs) play a central role in understanding natural evolution and the development of biological organisms from cells. In this paper, we apply GRN principles to the WSN system and propose a new GRN model for decentralized node scheduling design to achieve energy balancing while meeting delay requirements. Through this scheme, each sensor node schedules its state autonomously in response to gene expression and protein concentration, which are controlled by the proposed GRN-inspired node scheduling model. Simulation results indicate that the proposed scheme achieves superior performance with energy balancing as well as desirable delay compared with other well-known schemes.

"lux et sonitus" is an audiovisual art exhibition series with an artistic combination of music and video at its center. Since its first introduction in 2013, the series have been held five times under the theme of "exhibition of music", presenting works featuring both audio and visual media in an effort to explore the key issues in the field of audiovisual art. In addition to the previous achievement of the exhibition, recent works from the series feature new concepts that explore the possibility of expanding the realm of synesthesia. In this paper, details of the entire series are summarized. In addition, theoretical background behind creative results of the series is analyzed in the context of music, synesthesia and space found in Nam June Paik's audiovisual artwork as a source of inspiration. This will contribute to establishing a vision for the creation/analysis of audiovisual art in the future.

Jainpalkwangdae(慈仁八廣大) of Kyungsan area in Kyungbuk province was restored through over 50 years gap. This play basically has the structure of conflict - reconcillation, which is differentiated from a masque and a tightrope walking. The characters of this play are a nobleman, Malttuki (a servant), a legal wife and a second wife. Their personality is deviant from a existing Korean masque. This weird and artificial appearance may be a problem in the process of restoration. Otherwise, it might be a very different transmission type of masque. Therefore, we need to investigate why Jainpalkwangdae is different from a traditional masque.

생체 모방 로봇은 생명체에서 영감을 얻어 새로운 로봇분야를 개척하고 기존의 로봇으로는 하기 힘들었던 한계점들을 극복하는데 목적이 있다. 이러한 생체 모방 로봇은 간단한 생물체의 형태 혹은 메커니즘의 모방으로부터 시작되어 바퀴가 갈 수 없었던 험지, 혹은 하수구, 좁은 통로에서 사용될 수 있는 로봇들을 개발하는 데 초점이 맞추어져 있었다. 이러한 로봇들의 예로써는 크게 이족 보행, 4족 보행, 다족 보행 로봇 등 생물체의 이동 메커니즘을 모방한 로봇들이 있다. 이러한 연구들은 기존 로봇에 사용되었던 재료, 제작 방법을 이용한 것이었다. 하지만 최근 생체 모방 로봇 기술은 새로운 접근 방법, 새로운 재료를 이용한 제작방법으로 기존의 로봇과는 다른 형태로 진화하고 있다. 이러한 기술은 경량화 기술, 초 소형화 기술, 3차원 프린팅 기술 그리고 소프트 물질을 이용한 제작 방법 등이 있다.

The aims of the study were to review the transcriptions of the famous cuneiform tablet 'Plimpton 322' and interpret the meanings of the numbers. Since the tablet was found, many scholars tried to interpretate the relation among numbers. Neugebauer & Sacks, Buck, and Robson's finding are reviewed. This tablet must be the most well known and taken as an important role to complete a proof of the Pytagoras' theorem before the development of Greek Mathematics.

The Purposes of this article are to find Christian religion and Germany expressionism which were background of Nolde's art and analyze formation and special quality, expression mode of holy picture. If synthesize contents of these analysis, we could know that faith is giving religious inspiration continuously during his lift to Protestant experience through the Bible. Though there is some difference by time but we could foretell that he accomplished modern holy picture of new sensitivity by doing individual expression with equal Bible subject traditionally in 20th century that change unlike existent holy picture with these motive power. That is, with new trend which religious inspiration as imagination which spring up in experience that is not experience of artificial Christian religion is then expressionism various that historically, he accomplished unique holy picture to related each other with the historic event.

In this paper, we proposed on the direction of self-repairing mimicking the cell on the digital system design. Three-dimensional array of cells rather than using the original structure of FPGA, an array of blocks for efficient error detection methods were investigated. With a certain regularity, so the design method in detail by dividing the full array. The digital circuits can be detected fault location easily and quickly.
