BACnet(Building Automation and Control networks) is a standard data communication network protocol designed specifically for building automation and control systems. BACnet provides BACnet/IP Protocol for data communication through the Internet. BACnet device uses BBMD(BACnet Broadcasting Management Device) to deliver BACnet broadcast messages. In this study, we propose a fault tolerant BBMD in the BACnet/IP protocol. The fault tolerant BBMD improves the connectivity of BACnet/IP networks by inheriting the operation of original BBMD in the networks. The fault tolerant BBMD is implemented with added functions to the original BACnet/IP protocol so that it can provide backward compatibility with the original BACnet/IP devices. We examined the validity of the fault tolerant BBMD using an experimental model.

BACnet(Building Automation and Control networks) is a standard data communication protocol designed specifically for building automation and control systems. BACnet provides BACnet/IP Protocol for data communication through the internet. BACnet device transmits BACnet broadcast messages and BACnet/IP messages using conventional IP technologies. Specially, BBMD(BACnet Broadcasting Management Device) is used to deliver BACnet broadcast messages. In this study, we propose a mechanism of fault tolerant BBMD in the BACnet/IP protocol. The Fault Tolerant BBMD mechanism(FTBM) improves the connectivity of BACnet/IP networks by inheriting the operation of BBMD in the networks. The FTBM is implemented with added functions to the original BACnet/IP protocol so that it can be applied together with original BACnet/IP devices. We also prove the FTBM's backward compatibility with original BACnet/IP protocol using experimental analysis.

Modern cities are weak in traditional culture with the lack of characteristics and the problem of environmental deterioration. As the important carrier of urban culture, landscape architecture should be responsible for solving these problems. The urban need is paid much attention in the design of South Bank Linear Park in Meizhou city. Following the principle of inheriting and developing urban traditional culture, the design of the whole park is integrated with Hakka culture in Meizhou, which forms the landscape with local features and modern landscape architecture culture, and promotes the urban culture construction.

It is known that a single-key and a related-key attacks on AES-128 are possible for at most 7 and 8 rounds, respectively. The security of CMAC, a typical block-cipher-based MAC algorithm, has very high possibility of inheriting the security of the underlying block cipher. Since the attacks on the underlying block cipher can be applied directly to the first block of CMAC, the current security margin is not sufficient compared to what the designers of AES claimed. In this paper, we consider HMAC-DM-AES-128 as an alternative to CMAC-AES-128 and analyze its security for reduced rounds of AES-128. For 2-round AES-128, HMAC-DM-AES-128 requires the precomputation phase time complexity of $2^{97}$ AES, the online phase time complexity of $2^{98.68}$ AES and the data complexity of $2^{98}$ blocks. Our work is meaningful in the point that it is the first security analysis of MAC based on hash modes of AES.

The Han Dynasty was the great unification dynasty in history after the Qin Dynasty. Since the Han Dynasty inherited the Qin system, the seal script of the Han Dynasty developed continuously based on inheriting the Qin Small Seal Script. With the progress of social productivity, the Official Script gradually replaced the Seal Script in the Han Dynasty, but the Seal Script did not disappear completely; instead, a special line of development arose under the influence of the Official Script. Through the study of seal script of Han Dynasty inscriptions, this paper understands that the practical function of seal script of inscriptions has been weakening under the influence of clerical script, but the aesthetic value has been increasing day by day. Moreover, there were new artistic innovations in the context of the development of the diversification of inscriptional forms, and its emphasis on social role, cultural status, and the presentation of an aesthetic style that had a profound impact on later generations are worth studying.

This study is intended to examine the common features of costume images in science-fiction (SF) movies that deal with current socio-cultural situations by examining their themes and tones about the future it can be generally concluded that costume images of SF movies are divided into two patterns : one inheriting traditional styles constructed on linear progress and the other based on dismantiling the tradition. this analysis is made through the research of actual cinematic contexts on the common features of multiple styles shaping the two patterns of costume images. The results can be summarized as the following: The former is related with the future built up on the basis of belief in reasonal progress rooted in the Enlightenment reasonable plan for ideal social order and strong faith in uniformity. So It shows functional uniformity disregarding wasteful competitiveness in consumption and luxuriousness and clothing that has the aesthetic value of purity without emphasizing human body or sensuality are presented. On the other hand SF movies which show the uncertain costume image as the meaning of dismantling of tradition take up a rather critical view of assumption that society can move toward utopian future as it searches future images in the notion of hetero-topia by emphasizing pluralism consequently as for clothing diversity and uncertainty in post-modern style are presented destroying modernistic dichotomy and the assumption of Utopian clothing made in the notion of modern progressivism.

VoIP provided voice service using Internet is receiving footlights when it escapes an initial curiosity. VoIP interest became larger, because it can transfer existing phone service and deliver voice data through internet technology. Is inheriting as it is threats of IP base because a VoIP technology provides audiocommunication service taking advantage of an existing IP technology, and have new threats that happen from new know-hows for VoIP service offer. In this paper, presented about problem and consideration and countermeasure of examines about security threat of VoIP service, and applies security.

Ordinary people generally bury or burn placenta when the baby was born. But, Joseon royal family put placenta in pot and then buried it in propitious site praying for good health and long life. After that baby had become the king of Joseon, people built stone figures formed fixed type at that place. It is called gabong-taesil(加封胎室). The purpose of this study is to figure out the type and characteristics of the King Taejo's taesil in Joseon Dynasty. The King Taejo's taesil had built first as soon as Joseon was established circa 1393, and repaired largely in 1689. Since then, this was damaged by the Japanese Empire and assembled in recent days at near place from the original place. Center piece of taesil remains the original form, and the rest of stone figures is assumed to be rebuilt in 1689. But, some materials like sangseok(裳石) and jeonseok(磚石) are assumed that are original stone figures or were made, assembled by the style of then. Considering most of remained taesil is a relic of the latter part of Joseon Dynasty, the King Taejo' taesil has high cultural value as the first gabong-taesil of Joseon Dynasty inheriting Goryeo Dynasty type.
