도시재생은 전 세계적으로 주요 국정과제로서 큰 관심을 보이고 있는 분야이다. 아직 초기단계인 우리나라의 도시재생이 성공적으로 정착하기 위해서는 선행된 도시재생선도지역에 대한 현장 중심의 의견 및 사업의 성과를 분석하고 검토하는 노력이 필요한 시점이다. 이에 본 연구는 도시재생사업의 만족도 평가에 영향을 주는 도시재생계획요인을 사업시기별로 분석하는 데 목적이 있다. 본 연구에서는 적극적인 주민참여로 도시재생사업이 활발히 진행되고 있는 경상북도 영주시에 대하여 지역주민 및 전문가를 대상으로 설문조사를 실시하였으며, 설문결과를 바탕으로 빈도분석 및 상관관계분석과 다중회귀분석을 수행하였다. 분석 결과, 도시재생사업을 추진함에 있어 주민들이 가장 중요하게 생각하고 진행하면서 만족도가 높은 요인은 '공동체적 요인'인 것으로 분석되었다. 최종(현재)시점에서는 '공동체적 요인(0.387)'과 '물리적인 요인(0.454)' 모두가 만족도에 많은 영향을 미치는 것으로 분석되었다. '경제적인 요인(0.111)'에 대한 만족도는 더디게 진행되지만 물리적인 요인과 함께 현재시점에서 상승하였으며, '사회적인 요인(-0.007)'은 오히려 하향세를 나타냈다. 본 연구결과는 사업초기에 사회적 요인과 공동체 요인의 역할이 뒷받침되어야만, 장기적으로 물리적 요인과 경제적 요인의 상승효과를 가져올 것으로 판단된다.

최근 도시재생을 통해 도심 속 유휴공간의 재활용 방안에 한 관심도가 높아지고 있다. 이에 유휴공간을 재생하여 새로운 부가가치를 창출해 내기 위한 다양한 연구가 진행 중이다. 본 연구는 유형별 유휴공간의 재생이 주민 삶의 질과 지역경제 활성화에 어떠한 영향 관계 및 구조를 가지고 있는지 알아보기 위한 목적으로 진행되었다. 연구가설은 Smart PLS 3.0 패키지로 적합성 및 통계적 유의성 분석을 실시하여 검증하였다. 연구 결과 총 11개의 가설 중 '경제기반형 PLS 구조모형'에서는 6개의 가설이, '근린재생형 PLS 구조모형'에서는 4개의 가설이 검증되었다. 그 결과를 크게 몇 가지로 요약할 수 있는데, 첫째, 유휴공간의 재생(경제기반형, 근린재생형)을 통해 거주민의 삶의 질과 지역경제활성화를 동시에 만족하려면 문화적 차원에 대한 부문을 공통적으로 고려해야 한다. 둘째, 물리적 차원이 주민 삶의 질에 미치는 영향은 '경제기반형 PLS 구조모형'에서만 유의한 것으로 나타났다. 셋째, 사회적 차원은 '근린재생형 PLS 구조모형'에서만 유의한 것으로 도출되었다. 본 연구는 유휴공간의 재생에 관한 실증 결과를 분석했으며, PLS 구조 모형의 유형별 차이가 존재함을 밝혔다는 것에 의의가 존재한다.

Bone marrow aspirates concentrate (BMAC) transplantation is a well-known technique for cartilage regeneration with good clinical outcomes for symptoms in patients with osteoarthritis (OA). Magnetic resonance imaging (MRI) has an important role in evaluating the degree of cartilage repair in cartilage regeneration therapy instead of a second assessment via an arthroscopy. We experienced a case of hypertrophic regeneration of the cartilage and a presumed simultaneous regeneration of the posterior horn of the lateral meniscus after BMAC transplantation for a cartilage defect at the lateral tibial and femoral condyle. This report provides the details of a case of an unusual treatment response after a BMAC transplant. This report is the first of its kind to demonstrate a MR image that displays the simultaneous regeneration of the cartilage and meniscus with a differentiation ability of the mesenchymal stem cell to the desired cell lineage.

Today, modern society pursues the paradigm of creative city and regeneration. Cultural regeneration of revitalizing locality by utilizing culture catches attention, is a major approach. Public arts is considered as a catalyst of cultural regeneration, and it inspires vitality to declined districts. Gamcheon Culture Village, Busan has accelerated propagation of revitalization only in recent couple of years, and it has been developing with residents' participation continuously. The purpose of this research is to analyse the revitalizing effects of public arts introduction to Gamcheon Culture Village regeneration. In specific, social, cultural, economical, physical and environmental revitalization effects of the village were defined. The research method is questionnaire survey and 320 reponses from residents and visitors were collected. Data were statistically analyzed with SPSS18.0. The effects of public arts introduction to Gamcheon Culture Village regeneration are positive overall. However, according to the districts of the village, having diversity of art projects in both quantity and quality, the perceptions were different. Regeneration with utilizing public arts for revitalizing declined district, the Gamcheon case shed light on the future. The research indicated the value of public arts and some strategies of allocating art projects.

The number of vehicles applied diesel engine are rapidly rising for fuel economy. Accompanying this trend, application of an after-treatment system is strictly required as a result of reinforced emission regulation. The Diesel Particulate Filter (DPF) system is considered as the most efficient method to reduce particulate matter by car makers but also in retrofit market. In this paper we discussed the optimization of active regeneration timing by comparing the fuel consumption from back pressure caused by PM loading and from active regeneration. The effects of back pressure of DPFs during PM loading, active regeneration condition and engine emission(PM) on additional fuel consumption are experimentally investigated and the proper regeneration timings according to DPF systems and fuel loss for 160,000km are determined.

Suncheon City Regeneration Project is known as the concept of cultural residents. Through the previous projects, the residents' capabilities have been improved, and the projects have been carried out according to their strategies. For this reason, participants in urban regeneration projects are important. The purpose of this study is to actually identify the 'rescue center' and 'direct relationship' with the analysis utilizing the characteristics of social networks NetMiner solution of the participants, who led the project, Suncheon. Surveys and interviews were conducted for participants, and the characteristics of social networks were analyzed in time series to quantify and visualize the results. As a result of the analysis, social networks were changed among the participants before and after the urban regeneration project. Initially, loose networks were denser over time, and initially networks formed only around participants were expanded over time. Network analysis has revealed that the system is strengthening with urban regeneration projects in the form of public and public-private cooperation. This highlights the need for a city-centered urban regeneration strategy centered on people and shows that a dense network of participants can be a success factor.

Adventitious buds appeared within 2 weeks on the base of the petiole explants and increased for two months. A maximum of regeneration (15.6%) was obtained on the medium containing $1.5\;{\mu}M$ TDZ in combination with $1\;{\mu}M$ IBA. To know which explants are the best for the induction of regeneration, three explants such as leaf, petiole and leaf-petiole were used. Among the explant types, the leaf-petiole explant was significantly more effective than leaf and petiole for promoting adventitious shoots, with leaf-petiole inducing at the highest regeneration frequency (33.7%). The regeneration frequency of adventitious shoots in the leaf-petiole explants was significantly affected by leaf size and the position of explants. The leaf-petiole smaller than 5 mm leaf in width was induced at the highest regeneration frequency (68.9%). The smaller leaf sizes, the greater regeneration frequency. Also when the leaves are nearer to the shoot tip, the regeneration frequency is higher. When the rooted micro-shoots were transferred to the soil after growing for 6 weeks in the media, the survival rate was 90%.

In terms of urban regeneration of the present that focuses on a city's original history, culture and environment, it is now being understood as a concept of how a city by itself gets vitalized through local participation and communities. That is what indicates how a main agent of urban regeneration is changing to relevant local residents from public organizations and due to that reason, establishment of a differentiated urban regeneration policy that would reflect opinions of the locals is demanded. In the light of that, this study aimed to offer an urban regeneration project planning indicators targeting an old downtown area of Mokpo city which has been selected as an urban regeneration district. An AHP (Analytic Hierarchy Process) survey on the locals had revealed priorities of the indicators which helped the study to present indicators to be practically used for the urban regeneration project on the old downtown area in Mokpo.
