Information on the energy consumption of buildings that can be obtained through conventional methods is limited. Therefore, this study aims to develop a model that can support decision making about building facility management through digital transformation technologies. Through the IoT sensor, the building's energy data and indoor air quality data are collected, and the monitored data is visualized through the ELK Stack and produced as a dashboard. In addition, the target building is photographed with a 360-degree camera and maps using a tool to create a 360-degree tour. Using such digital transformation technologies, users of buildings can obtain various information in real time without visiting buildings directly. This can lead to changes in actions or actions for building management, supporting facility management decisions, and consequently reducing building energy consumption.

Digital transformation has become a pivotal focus in the Architecture, Engineering, and Construction (AEC) industry, driven by an urgent need to enhance productivity and optimize resource management. This transformation plays an essential role throughout the entire project lifecycle, from the early stages of conception to the final phases of completion. The paper underscores the critical importance of aligning digital transformation initiatives with the broader business strategies of AEC organizations. This alignment is key to gaining a competitive edge and fostering sustainable growth within the industry. The paper introduces a comprehensive and adaptable strategic framework for digital transformation. This framework is designed to be flexible, allowing AEC organizations to tailor digital transformation strategies to meet their specific needs and objectives. The framework not only addresses the technological aspects but also considers the cultural and operational shifts required for successful implementation. Moreover, the paper delves into various aspects of digital transformation, such as data management, workflow automation, and the integration of emerging technologies like AI and IoT in AEC processes. It discusses the potential barriers to digital adoption and offers strategies to overcome these challenges. This paper serves as an in-depth guide for AEC organizations looking to seamlessly integrate digital technologies into their business models. It provides valuable insights and methodologies that are crucial for any entity in the AEC industry striving to thrive in an increasingly digitalized world, making it a must-read for leaders and decision-makers within the industry.

This paper reports on a single-inductor multiple-output step-up converter with digital control. A systematic analog-to-digital-controller design is explained. The number of digital blocks in the feedback path of the proposed converter has been decreased. The simpler digital pulse-width modulation (DPWM) architecture is then utilized to reduce the power consumption. This architecture has several advantages because counters and a complex digital design are not required. An initially designed unit-delay cell is adopted recursively for the construction of coarse, intermediate, and fine delay blocks. A digital limiter is then designed to allow only useful code for the DPWM. The input voltage is 1.8 V, whereas output voltages are 2 V and 2.2 V. A co-simulation was also conducted utilizing PowerSim and Matlab/Simulink, whereby the 55 nm process was employed in the experimental results to evaluate the performance of the architecture.

인터넷 기술과 멀티미디어 기능의 발달로 인하여 디지털 콘텐츠는 새로운 성장 산업으로 주목받으며 다양한 경로를 통해 빠르게 보급되고 있다. 한 예로, 국내 디지털 콘텐츠 산업의 매출 규모 또한 2003년 이후 연평균 14.7%의 높은 성장률을 기록하고 있음에도, 정보 공학의 역기능 측면(저작권 침해, 부적합한 콘텐츠의 범람, 명예 훼손과 프라이버시의 침해)이 주요 문제로 대두되고 있다. 본 논문에서는 앞서 제시한 디지털 콘텐츠 유통 시 문제점을 해결하기 위하여 인터넷 환경 내 신뢰할 수 있는 디지털 콘텐츠 유통 아키텍처 (TDCDA)를 제시하였다. TDCDA는 콘텐츠 배포 시 신뢰성 확보와, 디지털 콘텐츠의 무결성 및 저작권 보호 메커니즘을 통한 안전한 콘텐츠 유통 방안을 소개하였고, 마지막으로 TDCDA의 알고리즘과 적용 방안을 제시함으로써, 실 웹 기반의 컴퓨팅 환경 내 활용 방안을 타진하였다.

Currently the locations of Unpleasant Facilities, especially surrounding the site selections, have been causing conflicts among the national government, many local governments and local residents. These Unpleasant Facilities must be necessary facilities for people's modern cultural lives, but there is no obvious solution that will make us all pleasant for the locations of them until now. In this study, we'll focused on applying the Floating architecture, one of the variety of marine structures, as an alternative location of Public service facilities accommodating Unpleasant Facilities which are classified as public service facilities. Of course, there should be beforehand studies in which we can define Unpleasant Facilities and analyse the conflicts surrounding the locations of them, and we can suggest that applying the Floating architecture should be the very solution to solve all these problems together. And as our main study, we should research and develop the structure and construction, maintenance and management of the Floating architecture which will be applied to the Unpleasant Facilities, together with the environmental considerations of their emergence on the waters. In future, to secure Unpleasant Facilities sites will become more and more difficult, and so Various kinds of public service facilities will have to be the subject to the floating construction.

This study examines the impact of the Internet on the organizational innovation. With the introduction of digital technology, the entire organizational process and structure is now being restructured. The purpose of this study is to develop a framework to help classify the organizational innovations and understand organizational innovation processes. This study suggests that the wide diffusion of digital technology has affected the modularization of the organizational routines and processes. The modularization of knowledge and organization give rise to a new organizational architecture, a modular architecture. In the Fordist regime, the characteristics of organizations were depicted as vertically integrated and tightly coupled system. The organizational processes and routines were tightly linked and integrated. However, the diffusion of Internet, which has a tendency to disassemble this tightly coupled system, has resulted in the emergence of loosely coupled and vertically disintegrated system. Eventually the modular architectures are emerging as a new organizational paradigm in the post-Fordist regime. In this study, the modes of organizational innovation is classified as follows. If the organizational innovation enhances both existing organizational components and tile tightly coupled architecture, it is incremental innovation (Mode 1): if it destroys both existing components and the tightly coupled architecture, it is radical innovation (Mode 4): however if only the tightly coupled architecture is transformed into the modular architecture and the codification of organizational component is enhanced, the innovation is architectural (Mode 3). The last one is component innovation (Mode 2), in which existing organizational components are destroyed but tightly coupled architecture is enhanced. It is argued that the organizational innovation process follows Mode I$\longrightarrow$ Mode II $\longrightarrow$ Mode III $\longrightarrow$ Mode IV in order.

다수의 처리 장치가 실시간 실현에 필수적이라는 것이 많은 디지털 신호처리를 일정한 시간 내에 하기 위한 요구 조건이다. VLSI 기술이 발전함으로 많은 기능 장치로 구성된 컴퓨터 시스템을 설계하고, 실현하는 것이 가능하게 되었다. 일정한 시간내에 높은 처리 능력을 갖음으로서 디지털 신호처리에 응용할 수 있는 VLSI 구조를 연구하는데 데이터 통신의 요구량과 계산의 복잡성을 최소화 할 수 있는 알고리듬의 개발이 요구된다. 이 문제를 해결하는 방법으로 DLSI 시스템이나 적응 시스템을 모델로 하는 효과적인 알고리듬을 조사하고 , 이 알고리듬을 실현할 수 있는 VLSI구조와 연관된 멀티 프로세서 시스템을 개발하는데 본 연구의 목적이 있다. 본 연구에서는 실시간 2차원 신호처리를 할 수 있는 새로운 VLSI 구조를 제안했다. 이 VLSI 구조는 칩 내부에서 단일 처리 장치가 갖는 개념을 다수의 처리 장치를 사용하는 경우로 확장하였다. 이 VLSI 구조는 입력 데이타의 크기가 증가함에 따라서 복잡성과 입력당 계산의 수가 증가하지 않는다는 장점을 갖기 때문에 매우 큰 2차원 데이타를 실시간에 처리할 수 있다.
