경의선 공원 프로젝트가 주택 가격에 미치는 영향

학위논문 (석사)-- 서울대학교 대학원 : 생태조경·지역시스템공학부, 2017. 2. 윤희연.Gyeongui Line Park is an urban park project that the City of Seoul has adopted as a means to revitalize declining neighborhoods. This study aims to analyze the projects effects on housing prices. Unlike extant hedonic studies, this analysis focuses on revealing the heterogeneous effects of the project by the development process, from inception to completion, to understand when and to what extent the park has influenced housing values in the host neighborhood. Findings indicate that the Gyeongui Line Park project has resulted in generally positive externalities to both apartments and multi-family dwellings, with the magnitude varying by relative location. The effects differ according to the projects phase and housing type: in the apartment market, values increased about 15% per 100-meter approach to the park, starting with the announcement of the parks procurement plan in 2006continued to increase through Phase I completionthen decelerated to 0–3% at the beginning of Phase II construction. For multi-family homes, the project corresponded with positive, but smaller, increases on housing values (about 2%) starting with Phase I construction in 2012, with the magnitude remaining at 1–2% from 2012 to the present. Findings from this study and its methodology will be valuable in determining the course of future planning efforts to maximize the positive effects of projects in urban revitalization practice.1.

생화학분자에 대한 테라헤르츠 분광학 및 의료영상에 대한 연구

DoctorThe development of Terahertz (THz) technology has opened the new way for useful applications in physics, chemistry, biology, and medicine. Interestingly, given the theoretical predictions, collective vibrational and torsional motions of biomolecules occur in the THz region. This has attracted much attention in characterization of biologically relevant materials at THz frequencies. THz time domain spectroscopy (TDS) can give good information of materials and is a powerful tool for probing the low frequency collective dynamics of biomolecules leading to conformational change and biomolecular function. Here, we report THz research in biology and medicine, including label-free DNA sensing, THz pulse imaging of human cartilage tissue and cervical cancer lymph node, and THz spectroscopy of crystalline α-lactose monohydrate and aqueous solution. Firstly, large contrasts in the complex refractive index between denatured and hybridized DNA were obtained, indicating that DNA samples of single and double strands can be readily distinguished. Secondly, we observed that each THz image exhibits the distinct structural organization of cartilage and clearly distinguishes between the abnormal and normal cartilage tissues. The water distribution in human osteoarthritic articular cartilage has been quantitatively characterized using THz TDS. We measured the refractive index and absorption coefficient of cartilage tissue in the THz frequency range. Based on our measurements, the estimated water content was observed to decrease with increasing depth cartilage tissue, showing good agreement with a previous report based on destructive biochemical methods. Thirdly, THz absorption spectra of crystalline α-lactose monohydrate showed strong absorption peaks at 0.1 - 2.0 THz. We examined β-amyloid peptide and amyloid fibril by using THz TDS. Collective vibrational modes in THz frequency region are affected by conformational change of biomolecules. Distinct spectral difference between β-amyloid peptide and amyloid fibril was observed in 0.1 ~ 2.0 THz. Finally, hydration dynamics in aqueous solution has been characterized. We precisely measured the dielectric constants of aqueous solution using THz TDS. As the solute concentration increased, THz absorption coefficients of aqueous solutions decreased due to the decrement of bulk water. It indicates that the biomolecule, bulk water, and hydration water in the hydration shell are closely correlated. The dielectric relaxation of sucrose solution was different from those in pure water

Extended TAM Analysis of a Residential DR Pilot Program

전력 수요가 증가하고 재생 가능 에너지에 대한 관심이 증폭됨에 따라, 수요를 억제하여 필요한 공급량을 줄일수 있는 수요반응 프로그램에 대한 관심이 증가하고 있다. 본 연구는 가정에 스마트미터를 구비한 국내 사용자들을대상으로 진행된 에너지 수요반응 실증사업에 대한 실증분석으로, 사전심층 인터뷰, 설문 및 기술수용모델 분석을통하여 가정 전력 사용자들이 수요반응 프로그램을 받아들이는 데 중요한 요인들을 살펴본다. 수요반응의 목표는 피크시간대에 미션이 발령되면 전력사용량을 평소보다 줄이는 것이며, 실험대상은 스마트미터 구입 경로와 에너지를절감했을 때 보상받는 방식에 따라 2개의 상이한 집단으로 구성되었다. 집단 A는 주로 IoT플랫폼 서비스에 가입하는 과정에서 마케터와의 대화를 통해 전체 서비스 중 하나인 스마트미터 서비스에 함께 가입하는 경로로 수요반응프로그램에 유입되었고, 보상으로는 통신비 할인을 받았다. 반면 집단 B는 스마트미터를 자발적으로 구매하거나 에너지 자립 마을 지역주민으로서 지자체 지원을 통해 스마트미터를 지원 받아 프로그램에 유입되었고, 미션 성공에대한 보상은 사회적 기부를 통해 이루어졌다. 분석 결과 집단 A는 인지된 용이성과 인지된 유용성 외에 인지된 유희성도 포함된 확장된 기술수용모델이 적합함을 알 수 있었고,집단 B는 모델의 적합도가 떨어지기는 하지만 집단 A에비해 인지된 유용성에 대한 중요도가 높음을 확인할 수 있었다. 이와 같은 결과는 집단 특성에 따른 프로그램 설계방향을 제시하여 향후 수요반응 프로그램을 효과적으로 운영하는 데에 도움을 줄 것으로 보인다. While electricity demand is generally increasing, stably controlling supply is becoming a serious challenge because renewable energies are becoming popular and often their productions are dependent on the weather. The 'demand response' programs can be used to complement the problems of renewable energies, and therefore their role is becoming increasingly important. This study provides an analysis of a demand response pilot that was conducted in Korea. The study first focused on questionnaire surveys and in-depth interviews, and the data was used to perform a Technology Acceptance Model (TAM) analysis. The goal of the pilot was to have the residential users reduce their power consumptions when an energy reduction mission is issued during peak load hours. The experimental subjects consisted of two groups with different characteristics. Subjects in group A obtained smart meters as an optional function of IoT platform service provided by a mobile service company, and received a charge deduction as their compensation. Subjects in group B either voluntarily purchased smart meters as individuals or received them by participating in an energy self-sufficient village program that was run by a local government, and were entitled to a donation as their compensation. With the analysis, group A was found to fit the extended technology acceptance model that includes perceived playfulness in addition to perceived ease of use and perceived usefulness. On the contrary, group B failed to fit the model well, but perceived usefulness was found to be relatively more important compared to group A. The results indicate that the residential energy groups behavior changes are dependent on each groups characteristics, and group-specific DR design should be considered to improve the effectiveness of DR.OAIID:RECH_ACHV_DSTSH_NO:T201723481RECH_ACHV_FG:RR00200001ADJUST_YN:EMP_ID:A079687CITE_RATE:0FILENAME:HCI학회논문지 12권4호(27)_정은아.pdfDEPT_NM:융합과학부EMAIL:[email protected]_YN:NFILEURL:https://srnd.snu.ac.kr/eXrepEIR/fws/file/08b929d1-1438-4138-bb7a-99a139599fb9/linkN
