Capriccio which has emersed in Italy of the 18th century is a new genre of the landscape painting. This genre represents reality, but it is very artificial product correspondingly its concept and character. It's birth place is distributed on various regions in Italy, but the main stage was Rome. Till the middle of the 18th century Rome was the Holy city of the Grand tour, the home of the Neo-Classicism and furthermore the field where archaeology and art history began to be instituted. On such historical situation the Capriccio came out and was recognized as the best popular genre in the visual art. It was favor of the art collection with the antiquity together and reflected the consciousness of the contemporary to the ancient. This study will examine the phenomena in the newly-developed archaeology and with few representative works of Giovanni Paolo Pannini as central term consider the Capriccio and the archaeological connotation. The systematical and institutional archeology which appeared at the age of the Enlightenment, on the contrary to the critical theories at the same time against capriccio, because it was regarded by them as paradoxical and too much sensitive, utilized it as a theoretical method very actively. Some among Historians and archaeologists did it, especially Francesco Bianchini distinguished the capriccio from simple imagination and made it a capacity of the knowledge. And through it he wanted to find out the historical truth. The visual art was influenced and encouraged by such attitude of the archaeology. However it's output spreaded out in various courses. While Giovanni Battista Piranesi, the best known Capriccist of the 18th century, tried to revive the antique through the epical value and his own imagination, Pannini gave priority to the strict historical research. In the such context Panni succeed Giovanni Battista Nolli who made the great map of the city Rome. Their Capriccio profited motive and was inspired by the historians and archaeologists such as Bianchini and Muratori. The Capriccio reflects not only the academic and popular interest for the antique, but also influenced on the upcoming scientific archaeology vice versa. It caused by their reasonable Interpretation and restoration of the antique through the visual medium. Finally as archaeological landscape Pannini's Capriccio is a historical case, in that the Capriccio applied the theoretical method of the archaeology to make art. It served as a momentum for the connotation to the archaeological thought.

Recently, some methods of converging heterogeneous fire sensor data have been proposed for effective fire detection, but the rule-based methods have low adaptability and accuracy, and the fuzzy inference methods suffer from detection speed and accuracy by lack of consideration for images. In addition, a few image-based deep learning methods were researched, but it was too difficult to rapidly recognize the fire event in absence of cameras or out of scope of a camera in practical situations. In this paper, we propose a novel fire detection system combining a deep learning algorithm based on CNN and fuzzy inference engine based on heterogeneous fire sensor data including temperature, humidity, gas, and smoke density. we show it is possible for the proposed system to rapidly detect fire by utilizing images and to decide fire in a reliable way by utilizing multi-sensor data. Also, we apply distributed computing architecture to fire detection algorithm in order to avoid concentration of computing power on a server and to enhance scalability as a result. Finally, we prove the performance of the system through two experiments by means of NIST's fire dynamics simulator in both cases of an explosively spreading fire and a gradually growing fire.

To understand the vegetation structure in the ridgeline area of Nakdong-jeongmaek, six primary areas in Nakdong-jeongmaek were selected and their vegetation distribution was surveyed considering the environmental conditions and artificial influences. According to the results of community classification based on TWINSPAN, the vegetation in the surveyed region was categorized into 9 groups: Betula costata-Quercus mongolica community, Q. mongolica community, Pinus densiflora-Q. mongolica community, P. densiflora community, Deciduous oaks-P. densiflora community, Deciduous oaks community, P. thunbergii community, P. koraiensis-P. rigida community, and Chamaecyparis obtusa-Alnus firma community. In Baekbyeongsan(Mt.) located in Taebaek-si of Gangwon-do, Betula costata-Quercus mongolica community was found, reflecting the environmental characteristics of northern temperate climate. P. thunbergii community appeared in Gudeoksan(Mt.) of Busan metropolitan city, which is near the coast. Since Gudeoksan(Mt.) is near to the downtown and its altitude above the sea is relatively low, people visit the area often. Therefore, C. obtusa and P. thunbergii have been planted for producing forest trees and implementing anti-erosion afforestation. In the other primary survey areas, Q. mongolica-dominant communities, P. densiflora-dominant communities, and deciduous oak-dominant communities, which are representative forest vegetation types of Jeongmaeks in South Korea, were mainly distributed, showing no significant difference compared to the forest vegetation types of other Jeongmaeks. Since the Nakdong-jeongmaek from south to north, it shows clear characteristics of vegetation changes between the northern temperate climate and the warm temperate climate of the south.

With the development of digital technologies, CAID became an essential part in the industrial design process. Creating photo-realistic images from a virtual scene with 3D models is one of the specialized task for CAID users. This task requires a complex interface of setting the positions and the parameters of camera and lights for optimal rendering results. However, the user interface of existing CAID tools are not simple for designers because the task is mostly accomplished in a parameter setting dialogue window. This research address this interface issues, in particular the issues related to lighting, by developing and evaluating TLS(Tangible Lighting Studio) that uses Augmented Reality and Tangible User Interface. The interface of positioning objects and setting parameters become tangible and distributed in the workspace to support more intuitive rendering task. TLS consists of markers, and physical controller, and a see-through HMD(Head Mounted Display). The user can directly control the lighting parameters in the AR workspace. In the evaluation experiment, TLS provide higher effectiveness, efficiency and user satisfaction compared to existing GUI(Graphic User Interface) method. It is expected that the application of TLS can be expanded to photography education and architecture simulation.

Recently, there have been large storage demands for manipulating multimedia data. To solve the tremendous storage demands, one of the major researches is the SAN(Storage Area Network) that provides the local file requests directly from shared-disk storage and also eliminates the server bottlenecks to performance and availability. SAN also improve the network latency and bandwidth through new channel interface like FC(Fibre Channel). But to manipulate the efficient storage network like SAN, traditional local file system and distributed file system are not adaptable and also are lack of researches in terms of a metadata structure for large-scale inode object such as file and directory. In this paper, we describe the architecture and design issues of our shared-disk file system and provide the efficient bitmap for providing the well-formed block allocation in each host, extent-based semi flat structure for storing large-scale file data, and two-phase directory structure of using Extendible Hashing. Also we describe a detailed algorithm for implementing the file system's device driver in Linux Kernel and compare our file system with the general file system like EXT2 and shard disk file system like GFS in terms of file creation, directory creation and I/O rate.

The rapid increase of the current marine accidents is mainly due to the human execution errors. In an effort to address this, various kinds of researches such as construction of the digital vessels and vessel information monitoring systems have been conducted. But for safe navigation of vessels, it lack on systems study which can efficiently store, utilize and manage the mass data accepted by the vessel. In this paper, we propose a VWS(Virtual World System) that is based on the architecture of intelligent systems RVC(Reactive Layer-Virtual World-Considerative Layer) model of intelligent autonomous navigation system. VWS is responsible to store all the necessary information for safe navigation of the vessel and the information services to the sub-system of intelligent autonomous navigation system. VWS uses topology database to express the specific problem area, and utilizes a scheduling to reflect the characteristics of the real-time processing environment. Also, Virtual World defines API for the system to reflect the characteristics of the distributed processing environment. As a case study, the VWS is applied to a intelligent ship autonomous navigation system, and simulation is done to prove the effectiveness of the proposed system.

This study suggests a new time distribution method of rainfall for small urban watersheds. IETD (Interevent Time definition) determination method considering basin characteristics and dimensionless accumulation rainfall curves involving rainfall events with shorter duration than 3-hours are suggested. A new definition of IETD is the time period from the end of a rainfall event to the end of a direct runoff. Using the method, we drive an area-IETD regression curve for the Joong-Rang basin. The rainfall event with 10 year-return periods, 2-hour duration is distributed and applied four urban watersheds. In the four watersheds, we calculate hydrographs for four watersheds using SWMM and compare them with ones of the Huff's distribution model. From the comparison, we find that peak flows resulted from the developed methodology are $11\sim15%$ larger than ones from the Huff's model. As conclusion, the Huff method should be adopted for the urban watersheds with careful verification.

A distributed multimedia school system is developed for the multimedia classroom at high school and university. The system is designed and implemented for students to improve the learning efficiency through the personalized multimedia contents and pace of learning. The previously developed multimedia information retrieval systems have some limitations on being applied to the multimedia classroom: expensive cost per stream or poor retrieval quality inappropriate for education, unscalability of system and service, unfamiliar proprietary client environment, and difficulty for teachers to use the authoring tools and manage the authored teaching materials. The system we developed overcomes the above problems. It is so scalable as to be applicable not only to a segmented classroom but also to the world wide Internet. The stream server is one of the components of the system: stream servers clients, a service gateway system, and a authoring management system. This paper describes the design and implementation of the stream server. A single stream server can simultaneously playback the multimedia streams as many as clients at one classroom. This is achieved only by the software engine without any changes of the hardware architecture. The systematic coupling with other components gives the scalability of the system and the flexibility of services.

The 'NIST Framework and Road Map for Smart Grid Interoperability Standards' proposes an architecture framework to secure the direction of development and standard interoperability of smart grid and provides a list of identified standard, standard cyber security strategies, and certification framework. In particular, SEP 2.0 and OpenADR 2.0 are the examples. SEP 2.0 and OpenADR 2.0 can functionally link HEMS and Smart Grid, but interoperability standards between the two protocols are not planned in above document. The OpenADR Alliance also announced that work is underway to define mapping tables for interoperability between OpenADR 2.0 and SEP 2.0, but no information is yet available. Therefore, In this paper, in developing energy efficiency improvement HEMS, we propose a mapping model that supports syntactic and semantic founded interoperability between SEP 2.0 and OpenADR 2.0b for ICT grid convergence based on the standard specification document of each protocol and confirmed through an example of the semantic mapping function based on the demand response service scenario.

Over the last 10 years, the number of disasters has been increasing in Korea. As a result, the need for temporary residences or shelters for disaster conditions is increasing. In this study, post-disaster refugees housing was developed using lightweight composite panels that are lighter than the materials that make up the existing shelter. To accomplish this, the structural performance of the lightweight composite panel was validated. Among the performance tests on the panels, the transverse load test was conducted according to the ASTM E 72 criteria. As a result of the experiment, when each specimen was subjected to a uniformly distributed load, the allowable load was determined according to the span. All the experiments were ended due to a loss of adhesive at the junction of the skin and core. Further analysis was conducted to calculate the shear stress when the junction was dropped. The mean shear stress at the adhesive surface of a specimen, 150 mm and 200 mm in thickness, was 0.0170MPa and 0.0156MPa, respectively. This suggests that similar values were obtained from panels of equal thickness. In addition, this stress provides a criterion of judgment that could be used to inspect the structural performance of the panels. The performance of the panel was evaluated based on the allowable load, but it may be possible to increase the strength of the lightweight composite panel by improving the joining method to avoid separation from the junction.
