In this paper, I proposes a method for performing single image super resolution by separating texture-spatial domains and then classifying features based on detailed information. In CNN (Convolutional Neural Network) based super resolution, the complex procedures and generation of redundant feature information in feature estimation process for enhancing details can lead to quality degradation in super resolution. The proposed method reduced procedural complexity and minimizes generation of redundant feature information by splitting input image into two channels: texture and spatial. In texture channel, a feature refinement process with step-wise skip connections is applied for detail restoration, while in spatial channel, a method is introduced to preserve the structural features of the image. Experimental results using proposed method demonstrate improved performance in terms of PSNR and SSIM evaluations compared to existing super resolution methods, confirmed the enhancement in quality.

Becoming construction projects larger and more complicated, and utilizing more varied and complex contracting and delivery systems in the industry, integrating information and managing constructability from project inception to completion became the most critical tasks for the successful project management. However, current industry practices of constructability analysis which are too much dependent on field engineers and managers' experiences, are not performed efficiently and also not managed effectively. Then the scope, method, and procedure in performing analysis tasks are not certain as well as not systematic, In addition, due to using 2D based drawings and documents, information required at project phases for the analysis is inconsistent and inaccurate. This study aims to suggest the use of BIM technology and functions for solving various problems of current constructability practices. In particular, constructability analysis tasks performed at design and construction stages are identified and their adaptability, applicability, and benefits of BIM are investigated through interviews on constructability and BIM professionals in the industry.

오늘날 전 세계적으로 급격한 에너지 사용과 이에 따른 온실가스의 증가로 기후변화 현상이 세계 곳곳에서 나타나고 있다. 이러한 지구온난화는 산업화에 따른 에너지소비가 주요한 원인으로 꼽히고 있으며, 선진국에서는 에너지소비와 이산화탄소 방출을 줄이기 위한 노력을 적극적으로 추진하고 있다. 우리나라에서도 2013년부터는 온실가스 감축 의무 이행국에 포함될 것으로 예상되어 지속가능(sustainable)한 국가발전을 위한 노력을 기울이고 있으며, 저탄소 녹색성장을 화두로 적극 대처하고 있다. 우리나라는 세계10대 에너지 소비국이면서 97%의 에너지를 외국에 의존하고 있다. 더욱이 이산화탄소배출량은 세계9위를 차지하고 있다. 따라서 향후 선진국과 경쟁을 하기위해서는 산업구조를 시급히 개선하여 에너지 소비를 줄이고 이산화탄소 배출을 적극적으로 억제하여야 한다. 현재 국내에서 사용되는 전체 에너지 가운데 건물에서 소비되는 에너지는 약 40%정도를 차지하고 있다. 이에 따라 건물에서의 에너지 사용량을 줄이고 환경부하를 저감할 수 있는 친환경 건축물의 구축이 시급하며, 관련 기술 개발 및 실제 건축물에 적용을 위한 노력이 진행되고 있다. 친환경 건축 관련 기술은 오늘날 많은 신축 건물에 적용되고 있으나, 그 성능은 아직까지 미흡한 부분이 많다. 건축물의 설계단체에 환경성능 분석결과가 적절히 반영된다면 적은 노력과 비용으로 매우 우수한 친환경 건축물을 구축할 수 있다. 하지만 기존의 설계절차 및 성능분석 지원 시스템으로는 건축 설계단계에서 에너지 소비량을 포함한 친환경 성능을 분석하기에 많은 시간의 투입과 전문가의 도움이 필요하다. 다행히 최근에 이러한 건축물의 친환경 성능 분석에 건축정보모델링(Building Information Modeling, BIM)기술을 활용할 수 있는 연구가 진행되고 있다. 건축정보모델링은 컴퓨터를 이용하여 건축물의 설계 데이터뿐 만 아니라 관련 모든 정보를 모델링 하여 건축물의 설계단계부터 건물의 폐기단계까지 활용되는 기술이다. 이미 선진 외국에서는 활발한 연구가 진행되어 실용적용 단계에 있으며, 국내에서도 초기 연구가 진행 중이다. 이러한 건축정보모델링 기술이 친환경 건축물 구축기술에 활용된다면, 친환경 건축물 구축 및 성능 향상에 많은 도움이 될 수 있을 것으로 기대된다. 또한, 녹색 성장의 기반이 될 수 있는 건축물의 설계 및 시공, 유지관리가 가능해 질것이다. 따라서 이번 연재에서는 지속가능한 설계와 건축정보모델링을 활용한 건축 환경 성능을 분석에 관한 내용을 주제별로 다루고 그 사례를 살펴보고자 한다.

The need for Maker Education has received attention as an educational environment for cultivating the active and creative ability that can solve new problems in this era, and it is applied in various educational fields. Many of them use Design Thinking as a stage of maker activities. However, the educational value of each concept has not been magnified, since maker programs are designed by simply borrowing steps without considering the similar but different features of them. Therefore, this study developed a model of Maker Education utilizing Design Thinking based on complementary relationships. To this end, formative research methodology was conducted by the following procedures, developing a draft, conducting a formative evaluation, and completing the final model. As a result, the stages of Maker Education were visualized and detailed activities and instructing strategies in each step by reflecting the features of Maker Education, the autonomy of the learner and producing visible outputs using various tools and materials, and Design Thinking, the specific process of solving problems and enabling social participation.

This study evaluates potential sources of errors in k-NN(k-nearest neighbor) algorithm such as procedures, variables, and input data. Previous research has been thoroughly reviewed for understanding fundamentals of k-NN algorithm that has been widely used for short-term traffic states prediction. The framework of this algorithm commonly includes historical data smoothing, pattern database, similarity measure, k-value, and prediction horizon. The outcomes of this study suggests that: i) historical data smoothing is recommended to reduce random noise of measured traffic data; ii) the historical database should contain traffic state information on both normal and event conditions; and iii) trial and error method can improve the prediction accuracy by better searching for the optimum input time series and k-value. The study results also demonstrates that predicted error increases with the duration of prediction horizon and rapidly changing traffic states.

As the competition between companies are deepened, the number of companies adopting six sigma principles, which is one of the innovative management strategies, are increasing. According to this trend, the changes in both strategies and methodologies of six sigma are continuous. However, the evaluations and the management principles included in the process after the six sigma applications are insufficient, and the cooperation between the parties in the company is also not enough because the application process of six sigma is too complex and not efficient. In order to solve this problem, a research for developing the methodology which can learn about and do six sigma applications is so necessary, specifically for expanding the six sigma applications and introducing the participation of all company members. The purpose of this study, therefore, was to develop and present more efficient Six Sigma applied process by reducing the existing unnecessary steps in improvement one, by applying the examination method of wasteful elements on the potential factors, through analyzing the Six Sigma DMAIC applied case in the construction industry. The result of those application showed that the detection of potential factors using wasting elements was possible in measurement step and that it was possible for the improved process with reduced steps compared to existing process while to remain the outcomes. It is considered that the performance rate of Six Sigma project will be improved significantly because the reduction in the improvement step does not affect the improvement effect within the whole Six Sigma project.

Recently our country need to change about hospital building operation and business change. The recent real estate development projects are made in very complex due to the diversity of development method or its legal aspects. Under such a real estate investment, the review of investment yield rate is fundamentally important for the one that invests and the one that finances it. Previously, the focus was in the review of the time to turn the surplus or the plan for making repayment of the borrowings, and without the analysis of sufficient investment yield rate. For a simple issue of finding the most advantageous project method, there is a need for reviewing the taxation issues, fund procurement method, legal aspects, policy analysis aspects and others. Therefore, the real estate investment is now likely to encounter the form of having the time of venture as well. In conclusion, the scientific and reasonable decision making in investing on the real estate does not suggest the absolute evaluation standard but the need and the use are more and more demanded.
