레저용 플로팅 건축물은 구조물 안전성, 건축물 용도, 건설 및 관리 경제성, 주변 지역이나 도시와 개발 연계성, 해양환경에의 영향 등을 고려할 때 입지선정에 대한 체계적 지침과 합리적 기준이 반드시 필요하다. 그러나 현재 우리나라에는 레저용 플로팅 건축물이 많이 계획되고 설치되는 시점에 있음에도 불구하고 입지선정에 관한 연구나 지침이 전혀 없는 실정이다. 따라서 본 연구는 레저용 플로팅 건축물의 입지선정을 위해 체계적 입지선정프로세스. 합리적 입지선정기준 및 입지평가지침을 제시하는 것이 목적이다. 본 연구에서는 지자체나 민간 기업에서 레저용 플로팅 건축물을 계획할 경우 체계적이고 합리적 입지선정에 활용할 수 있도록 입지선정과정, 입지선정기준, 입지평가항목 및 요인을 그림과 표로 알기 쉽게 제시하였다.

Patient Navigation Program (PNP) is considered as an important implementation of health care systems that can assist in patient's treatment. Due to the feasibility of PNP implementation, a systematic reuse is needed for a wide adoption of PNP computerized system. SPL is one of the promising systematic reuse approaches for creating a reusable architecture to enabled reuse in several similar applications of PNP systems which has its own variations with other applications. However, stakeholder decision making which result from the imprecise, uncertain, and subjective nature of architecture selection based on quality attributes (QA) further hinders the development of the product line architecture. Therefore, this study aims to propose a quality-driven approach using Multi-Criteria Decision Analysis (MCDA) techniques for Software Product Line Architecture (SPLA) to have an objective selection based on the QA of stakeholders in the domain of PNP. There are two steps proposed to this approach. First, a clear representation of quality is proposed by extending feature model (FM) with QA feature to determine the QA in the early phase of architecture selection. Second, MCDA techniques were applied for architecture selection based on objective preference for certain QA in the domain of PNP. The result of the proposed approach is the implementation of the PNP system with SPLA that had been selected using MCDA techniques. Evaluation for the approach is done by checking the approach's applicability in a case study and stakeholder validation. Evaluation on ease of use and usefulness of the approach with selected stakeholders have shown positive responses. The evaluation results proved that the proposed approach assisted in the implementation of PNP systems.

최근 FCC(Federal Communications Commission)에서는 통신 채널의 부족을 극복하기 위해 기존의 허가된 사용자의 무선 주파수에 대한 비 허가 사용자의 사용을 고려하고 있다. 이에 채널을 실시간으로 감지하고 선택하는 CR의 개념이 도입되어 IEEE 802.22 WRAN(Wireless Regional Area Networks) 워킹 그룹에서 CR(Cognitive Radio)의 기술개발을 진행 중에 있다. CR의 기술을 사용함에 있어서 채널을 선택하는 기준에 따라 네트워크의 통신 효율에 상당한 영향을 미치기 때문에 최적의 채널을 선택하는 방법이 중요하다. 따라서 본 논문에서는 효율적인 통신을 위해 무선인지 기술 기반의 정책에 따른 동적 채널 선택 구조(Policy-based Dynamic Channel Selection Architecture for Cognitive Radio Network)를 제안한다. 제안하는 동적 주파수 선택 방법에는 가중치 채널 선택 방법(weighted channel selection)과 순차적 채널 선택 방법(sequential channel selection)곡 혼합 채널 선택 방법(combined channel selection)의 세 가지 방법이 있으며 제안하는 방법을 사용함으로써 최적의 채널 리스트를 구성해 줄 수 있을 뿐만 아니라 동적으로 채널을 할당해 줄 수 있다.

Selection procedures of earth retention systems are increasingly complex and directly related to the serviceability of the retaining structure selection systems since significant changes in earth retention technology motivates the review of design, and selection processes of earth retaining structures. Collection and classification of retaining structure selection knowledge are key issues because two expert groups, geotechnical and structural engineers, are mainly involved in the retaining structure selection. The course of natural tendency of expert knowledge are investigated considering the decision factors. The decision factors for selecting retaining structures are divided into four categories: application of the structure, and spatial, behavior, and economic constraints.

In this paper, we proposed a hardware-oriented Genetic Algorithm Processor(GAP) based on subpopulation architecture for high-performance convergence and reducing computation time. The proposed architecture was applied to enhancing population diversity for correspondence to premature convergence. In addition, the crossover operator selection and linear ranking subpop selection were newly employed for efficient exploration. As stochastic search space selection through linear ranking and suitable genetic operator selection with respect to the convergence state of each subpopulation was used, the elapsed time of searching optimal solution was shortened. In the experiments, the computation speed was increased by over $10\%$ compared to survival-based GA and Modified-tournament GA. Especially, increased by over $20\%$ in the multi-modal function. The proposed Subpop GA processor was implemented on FPGA device APEX EP20K600EBC652-3 of AGENT 2000 design kit.

^x This paper aims to grasp the basical things of the architectural meaning of Bu - Seok Temple through the background of site selection and the analysis of arrangement change of it. For this purpose, I try to examine the process of folk- belief adhesion of Buddism and Feng - Shui as the choice factor of site when the temple was established, the spatial characters of the changing stage in arrangement. These characters of Bu - seok temple have significance for the basic study on the site selection and the spatial analysis of a mountainous district Temple in Shilla.

We focus on the issues of the non-linear return/risk relationship of IT investment and the balance between return and risk of IT portfolio. We develop an IT project selection model by integrating DEA models with Markowitz portfolio selection theory. The project data collected from a Fortune 100 company are used to illustrate the implementation of the model. In addition, computational experiments are conducted to demonstrate the validity of the proposed model.

This research aimed to identify walking trails' purpose of its use and the factors that influence the selection. For this, a survey targeting the walking trail users was conducted in 2016 to question the research aim stated above. The mean number of walking trail usage in a month was 2.51 times and the duration of use ranged from one to ten hours, with the average of 2.5 hours. The main reason for the usage was to maintain physical health and the following was for mental relaxation, thus showing more than 90% of the people concerned with physical and mental health. Walking trails near the residences had the greatest percentage and trails that include mountains, rivers, seas and lakes were the following. Trails near historical locations or countryside showed a lower percentage. The choices showed relevance to the proximity as a standard of selection. The next highest percentage was the convenience of transportation. Additionally, people that access the trails three or more times were inclined to be influenced by the installation of exercising equipment. The aspect of facilities showed that the place for relaxation was a significant selection factor such as bathrooms for 20s to 30s and exercising equipments for people older than 50. To access the walking trails, people reach it by automobiles, public transport, walking and bicycles and out of these, automobiles had the highest percentage.

For estimating the seismic demand of buildings, most seismic design provisions permit conducting linear and nonlinear response history analysis. In order to obtain reliable results from response history analyses, a proper selection of input ground motions is required. In this study, an accurate algorithm for selecting and scaling ground motions is proposed, which satisfies the ASCE 7-10 criteria. In the proposed algorithm, a desired number of ground motions are sequentially scaled and selected from a ground motion library without iterations.

The hybrid architecture of content delivery networks (CDN) and peer-to-peer overlay networks (P2P) is a promising technology enables effective real-time streaming services. It complements the advantages of quality control and reliability in a CDN, and the scalability of a P2P system. With real-time streaming services, however, high connection setup and media delivery latency are becoming the critical issues in deploying the CDN-P2P system. These issues result from biased peer selection without location awareness or content awareness, and can lead to significant service disruption. To reduce service disruption latency, we propose a group-based CDN-P2P hybrid architecture (iCDN-P2P) with a location/content-aware selection of peers. Specifically, a SuperPeer network makes a location-aware peer selection by employing a content addressable network (CAN) to distribute channel information. It also manages peers with content awareness, forming a group of peers with the same channel as the sub-overlay. Through a performance evaluation, we show that the proposed architecture outperforms the original CDN-P2P hybrid architecture in terms of connection setup delay and media delivery time.
