Daylighting affects the luminous environment and provides comfortable environment to the occupants. However, excessive daylighting might have negative influences on the visual comfort. Skylight, light intensity and distribution, and insolation could cause glare effects on the occupants. This study analyzed the effect of fenestration on the interior glare effects, and verified luminous environment adjustability through mock up test of conventional fenestration and 'Convergence Window System' by analyzation of luminance, luminance contrast, and glare effect. Consequently, room installed Convergence Window System was improved luminance contrast and PGSV Level.

Nickel hexacyanoferrate supported palladium nanoparticles (Pd-NiHCF NPs) were synthesized and studied for oxygen reduction reactions in direct methanol fuel cell. The NiHCF support was readily synthesized by a comixing of $Ni(OCOCH_3)_2$ and equimolar $K_3[Fe(CN)_6]$ solution into DI water under rigorous stirring. After the preparation of NiHCF support, Pd NPs were loaded on NiHCF via L-ascorbic acid reduction method at $80^{\circ}C$. Pd-NiHCF NPs were electrochemically active for oxygen reduction reaction in 0.1 M $HClO_4$ solution. X-ray absorption near edge structure analysis was conducted to measure the white line intensity of Pd-NiHCF to verify the OH adsorption. As a comparison, carbon supported Pd NPs exhibited same white line intensity. This study provides a general synthetic approach to easily load Pd NPs on porous coordination polymers such as NiHCF and can provide further light to load Pd based alloy NPs on NiHCF framework.

The change of digital convergence service environment converted the subject of design into user -centric one instead of developer-centric one, and changed the existing design environment focused on product development into the new user -centric design environment. Accordingly, GUI considering user's usability come to take big shares in those contents being used for multimedia equipments. However, as the present educational contents provide complex interface due to its design produced based on the existing e-learning system, they have many problems in that they don't consider user's usability. Thus this paper aimed to analyze actual examples through GUI elements of educational contents being used for multimedia equipments and attempt to suggest some directions for development. additionally, consider the various characteristics of digital convergence environment and educational contents, and try to set up strategic directions possible to utilize user'-centric interface elements more usefully and properly at the time to produce designs.

Today, the convergence of fashion design and digital technology has become a popular method and accordingly been tried variously in the fashion area. This study aimed to analyze the character of the collaboration with fashion and technology, and the meaning of technology as emotional expression methods. Selected designer's collections, literature and other related studies were reviewed in order to analyze the generative structure of the meaning and the binary-opposition in the convergence of body, fashion design and technology. Literatures and selected designer's collections were reviewed and quantitatively studies were performed to classify the convergence of human bodies, fashion design and technology through Greimas Semiotics rectangle based on binary-opposition of meaning and isotophy analysis. The research presents three types of fashion technology methods: mechanical movement, light/digital media, and virtual image. The convergence of fashion and technology was classified as the direct convergence and the indirect convergence. The direct convergence was characterized by variability and has automatic, independent movement, but the indirect convergence was shown closed and to have contradistinctive images.

This paper proposes a Distributed Transaction models based on the multimedia framework (MPEG-21) in digital convergence environment. Digital media market is growing up rapidly according to the extension of internet and universality of multimedia contents. So, importance of the effective management with the production and distribution of produced multimedia contents is becoming larger. For effective management of multimedia contents, the multimedia contents which are represented with different standard each other can be processed adaptively in the variable network environment. A free compatibility among the different terminals and standards are the essential particular should be offered for the digital convergence environment. A multimedia framework supports this compatibility and various multimedia services. In this paper, the Distributed Transaction models that multimedia contents can be circulated among the individual users safely and freely are proposed and the relation technologies are described.

As environmental pollution has become severe due to the rapid increase in pollutant generation in the air, measurement, collection, and analysis of atmospheric environment information plays an important role. However, it is difficult to measure the high-resolution and real-time atmospheric environment of the cities and tourist spots with high population mobility only by measuring equipment of stationary measuring stations. Therefore, this paper proposes a portable atmospheric environment measurement system for real-time measurement and monitoring of atmospheric environment information. The proposed system is a portable client with a low-power wireless communication method. It is possible to reliably transmit and receive the measured data through a multi-threaded server to monitor the trend of pollutants in the air in real-time.

산업과 ICT 기술간의 융합으로 새로운 부가가치를 창출할 수 있는 융합환경이 도래되어짐에 따라 경제성장과 더불어 우리의 삶의 질이 향상 되고 있지만 이러한 융합환경은 다수의 이익만을 제공하는 것이 아니라 융복합적인 보안 위협이 발생됨에 따라 다양한 보안문제를 발생시켰다. 이러한 보안 문제를 해결하기 위해서는 기존의 기술적인 접근으로 단편적인 보안 문제 해결방식이 아닌 통합적인 관점에서 보안문제를 접근할 필요가 있다. 그래서 본 연구에서는 전략적 관점, 관리적/운영적관점, 기술적 관점 등 다차원적인 관점에서 신뢰성 있는 보안 거버넌스 관리를 할 수 있도록 인적측면이 고려되어진 보안 거버넌스 프레임워크를 개발하였다. 그래서 이 프레임워크를 통해 보안 관리에 대한 단일 기준을 제시함으로서 최고 경영진들의 직접적인 관여가 가능하고 조직구성원들이 스스로 보안활동을 수행하고 책임 질수 있는 신뢰성 있는 보안관리체계를 구축할 수 있을 것이다.

Nowadays, the complexity of object tracking models among hardware applications has become a more in-demand duty to complete in various indeterminable environment tracking situations with multifunctional algorithm skills. In this paper, we propose a virtual city environment using AirSim (Aerial Informatics and Robotics Simulation - AirSim, CityEnvironment) and use the DQN (Deep Q-Learning) model of deep reinforcement learning model in the virtual environment. The proposed object tracking DQN network observes the environment using a deep reinforcement learning model that receives continuous images taken by a virtual environment simulation system as input to control the operation of a virtual drone. The deep reinforcement learning model is pre-trained using various existing continuous image sets. Since the existing various continuous image sets are image data of real environments and objects, it is implemented in 3D to track virtual environments and moving objects in them.
