Hardware implementation methods for Artificial Neural Network (ANN) have been researched for a long time to achieve high performance. We have proposed a Network on Chip (NoC) for ANN, and this architecture can reduce communication load and increase performance when an implemented ANN is small. In this paper, a multiple NoC models are proposed for ANN, which can implement both a small size ANN and a large size one. The simulation result shows that the proposed multiple NoC models can reduce communication load, increase system performance of connection-per-second (CPS), and reduce system running time compared with the existing hardware ANN. Furthermore, this architecture is reconfigurable and reparable. It can be used to implement different applications of ANN.

The design of a supertall building poses many challenges to the architect and engineer. Using Jeddah Tower as a case study; this paper intends to discuss a few of those challenges specifically related to the arrangement of programmed spaces in the tower, their functional connection by means of the vertical transportation system and physical connection with shafts which introduces the potential for stack effect in the building. The measures applied in response to and mitigation of these issues are discussed.

변화하는 기업 환경에 효과적으로 대응하기 위해서는 우리나라 중견 제조업 환경에 적합한 생산 마스터 정보관리 솔루션 도입이 시급하다 따라서 본 논문에서는 사용하기 편리한 사용자 인터페이스를 가지며, 다양한 시스템들과도 쉽게 연동할 수 있도록 표준 데이터 구조를 설계하였다. 또한 표준 데이터 구조를 중간언어 형태로 생성해 주는 자동화 연동 모듈을 탑재하고, 생산 관리 데이터의 확장이 가능한 생산 마스터 정보관리 솔루션을 개발하였다. 본 개발을 통하여 업무적으로는 관리하지 않았던 데이터를 관리함으로써 보다 효율적인 업무 프로세스 구성을 이룰 수 있을 뿐만 아니라 시스템 확장 시 보다 안정적인 시스템 구축을 위한 근간을 제공할 수 있다.

Performance-based seismic design (PBSD) is currently used for retrofitting of older buildings and the design of new buildings. Whereas, application of performance-based design for wind load is still under development. The tendency has been in the codes to increase wind hazard based on recent recorded events. Since tall buildings are highly susceptible to wind load, necessity for developing a framework for performance-based wind design (PBWD) has intensified. Only a few guidelines such as ASCE (2019) provide information on using PBWD as an alternative for code prescriptive wind design. Though wind hazards, performance objectives, analysis techniques, and acceptance criteria are explained, no recommendations are provided for several aspects like how to select a proper level of wind hazard for each target performance criterion. This paper is an attempt to explain current design philosophy for wind and seismic loads and inherent connection between the components of PBSD for development of a framework for PBWD of tall buildings. Recognizing this connection, a framework for PBWD based on limits set for serviceability and strength is also proposed. Also, the potential for carrying out PBWD in line with ASCE 7-16 is investigated and proposed in this paper.

In order to guarantee the user-requested quality-of-service(QoS) and keep the network utilization at maximum it is required to manage the network performance continuously after the network installation. The performance management function should provide the useful information for the network expansion and the capacity reallocation in the future. Currently the TINA provides the specification of the management function of configuration management connection management and fault management ; but the management function of performance management and security management are not well-defined yet. In this paper we propose a TINA-based performance management architecture for the efficient performance management of the heterogeneous networks or NEs with TMN and SNMP management functions. And we examine the proposed architecture into the ATM network (with SNMP and TMN) monitoring. The proposed architecture is based on the distributed processing architecture and the concept the TMN perfo mance management. The proposed architecture have been designed and implemented in multiprocess and multithread structure.

Since 2002, Architecture Schools in Korea was changing long traditional architectural education system from 4 years generalized architectural engineering curriculum to 5 years professional architecture program. Until 2010, 76 architecture schools have changed their program to 5 years course which was focused to design studio education. It was a very rapid change and there was not much time develop their own system which could represent institutional identity, character of students and local environment. Korea joined as a regular member of Canberra Accord in 2010 and it is meaningful to compare Korean architecture program contents to another country education contents. US architecture programs were selected for this comparison study. The goals of this study are to create a comparable understanding the form of contents of Architectural Education in US and Korea and to verify the substantial equivalence of these systems. To achieve above goals, three public institutes of each country were selected and analyzed with general information, history, resources, curriculum and the matrix of Student Performance Criteria for quantitative comparison. For qualitative comparison education context of programs were analyzed with program missions, the way of advising, professional connection and distribution of faculty loads.

Korea is closed to China in the geographical position and is related to China as two countries have developed similar culture, art, and social systems. Architecture is a kind of culture and has advanced in the wooden architecture with a considerable change. The study investigated a phylogenetic relationship between two countries based on characteristics of architectural universality. With comparison and analysis on the common feature and difference of the beam and structure in the wooden architecture from the Koryo and Zhejiang Province(China), the systemicity of the wooden architecture was examined. The beam is a part of timber which is consist of the wooden structure frame and also a crucial subject to understand a development process of the wooden architecture.

School architecture has been functionally changed a lot as well as the changes of school education. School tries to educate people to recognize their dignity and give life to their personality. In addition, it's also important for school facilities to contribute to making social communities as community establishments beyond its own purpose of education. Researches for school architecture have been going on to make facilities suited for that. At this point of view, this research is looking for methodology contributed to design institutions suitable for education through working on precedents for planning school design. One way to this is studying the method of designing of the design team, 'Coelacanth', selected for good architecture in Japanese school architecture so many times and finding out its connection to interior.

Recently, many New Han-oks have been constructing in all over the country to popularize as a type of green house. But, achievement of thermal performance of external wall is still the very important issue to become popular. Purpose: The purpose of this study is to verify the thermal performance level of modern New Han-ok through Temperature Difference Ratio inside(TDRi) analysis at corners of the external wall in Han-ok. Method: To achieve this goal, measurements were carried out in 12 Han-oks(experimental mock-up(1), exhibition Han-ok(1), happy village Han-oks(10)) by taking a infra-red thermography using thermal video system. Following are analysis items about connection joint between wall and wood columns of external wall conditions; the part between external wall and external wall(2D), external wall and ceiling(or floor)(2D), 2 external walls and ceiling(or floor)(3D) and so on. Result: It was analyzed that the probability of condensation at most of connection joint appear high and TDRi of 3D corners is higher than that of 2D corners in general. It means that the development of construction techniques about connection joint between wood columns and external wall is still required. The results of this study may be used to improve the construction technology of new Han-ok and as a basis for the specifying the desired thermal comfort environment of dwelling.

무량판 구조의 슬래브-기둥 접합부는 뚫림전단파괴에 취약하여 구조 성능을 향상시킬 필요가 있다. 본 연구에서는 새로운 슬래브-기둥 접합부 전단 보강 방법인 래티스 보강의 강도와 변형 능력을 평가하기 위한 실험 연구를 실시하였다. 주기 횡 하중을 받는 4개의 래티스 보강 접합부에 대한 실험을 실시하였으며, 비교를 위하여 전단 무보강 시험체, 스터드 레일, 전단 밴드, 스터럽 등 다양한 기존의 전단 보강 방법으로 보강된 실험체에 대하여 실험을 실시하였다. 실험 결과, 래티스 보강은 강도와 변형 능력면에서 모두 우수한 성능을 나타내었으며, 현행 기준의 예측 강도를 현저히 상회하는 강도를 나타내어 전단 보강에 매우 효율적인 보강 방법으로 평가되었다. 반면에 스터럽, 스터드 레일과 전단 밴드 실험체는 전단 무보강 실험체에 비하여 강도 증진 효과가 크지 않거나, 그 강도에 미치지 못하는 강도를 나타냈다.
