본 연구에서는 스마트시티 조성에 있어 해당지역의 리빙랩 조성에 맞춰 사업의 전과정을 공유하고, 개별 솔루션별 주민들의 피드백 지향을 통해 지역주민의 체감도를 높일 수 있는 대안적 방안을 제안하였다. 이는 사업의 실제 사용자인 지역주민의 요구사항에 맞춰 지역이 안고 있는 현안 문제를 해결해야 함을 전제로 하고 있으며, 이를 위해 스마트시티 리빙랩의 특성과 유형별 사례를 통해 주요 핵심요소를 파악하였고, 실제 스마트시티 조성에 맞춰 지역별 리빙랩 운영성과를 정리하였다. 향후 지역주민의 체감도를 높일 수 있는 대안적 고찰과 함께 사업 유형별 리빙랩 모델에 대한 성과측정의 필요성과 유형별 모델의 정합성 분석도 이후의 종합적인 성과공유를 통해 진행되어야 한다 In this study, an alternative plan was proposed to share the entire process of the project by creating a living lab in the area to create a smart city and to increase the perception of local residents through the direction of feedback from residents for each solution. This presupposes that the current issues facing the region must be resolved by the needs of residents, who are actual users of the project, and to this end, major key elements were identified through the characteristics, and type-specific cases of smart city living labs, and the actual smart city creation summarized the operation performance of living labs by region. In addition to alternative considerations that can increase the perception of residents in the future, the necessity of measuring the performance of the Living Lab model by project type and the analysis of the consistency of the model by type should be conducted through comprehensive performance sharing. However, this study has the following limitations and implications. It is difficult to standardize the living lab process by generalizing the characteristics of individual cases, and it is also necessary to design a system of roles and requirements according to the level of participation of residents by combining the size and regional factors of the project site. In particular, local governments' resident participation projects also require continuity of resources that can be used, and it is expected that living lab-type performance sharing will continue to occur for projects with various purposes in the future.

We studied the dielectric and dynamic mechanical losses according to the quenching condition in low density polyethylene being used to power cables. According to severe quenching condition, characteristics of the temperature in internal friction los peak have decreased the magnitude of loss peak as amorphous region lengthen. From now on, the frequency dependent characteristics of dielectric loss have investigated at room temperature, and the dielectric loss peak due to interface polarization, between crystal and amorphous region, occurs about 30[Hz], and that, the peak due to orientation polarization in correspondence to the loss peak in internal friction has observed at about 3 [MHz]. As quenching velocity increased, the effect on quenching condition about the dielectric loss has decreased the magnitude of the loss peak. Thus, estimation has been carried out on the activation energies nd the degree of crystallinity by means of X-ray diffraction are obtained as follows: room quenching : 26.4 [kal/mole] and 54.73 [%], ice quenching : 25.6 [kcal/mole] and 48.47 [%], liquid nitrogen quenching specimens : 22.56 [kcal/mole] and 40.95 [%].

The objective of this study was to estimate the investment limit in equipment capital by Capital Recovery Method. The data used was collected from 23 Hanwoo(Korean Native Cattle) farms in 1994. The necessary time for herd size expansion was average 5 years from opening(9.7 heads) to 50 heads, 4 years from 50 to 100heads, 3 years from 100 to 150 heads, and 2 years from 150 to 200 heads, respectively. It took 14 years from opening to 200 heads of herd size. The debts for fattening cattle farms were 15.2million won for the size of 50 heads, 37.1 million won for the size of 100 heads and 89.0 million won for the size 200 heads, respectively. Average rates of debt interest were 5.1 % 7.2 and 10.8, correspendingly. As the hear size increased, debt interest rates also increased due to government funds limit. The investment limits in equipment capital perfarm household were 77.7 million won for 50 heads, 135.1 for 100 heads, and 294.3 for 200 heads for 5,500 won per kg liveweight, 70.7 million won for 50 heads, 122.6 for 100 heads and 269.3 for 200 heads for 5,000 won per kg liveweight, 63.6 million won for 50 heads 110.0 for 100 heads and 244.2 for 200 heads for 4,500 won per kg liveweight.

1994년 처음으로 GM 토마토인 Flavr Savr가 시장에 나온 이후, 2010년 현재 140여 품목의 GM식물이 전 세계적으로 상업화되었다. GM식물들에 대한 안전성 승인여부의 확인 및 표시제관리를 위하여 이들 GM식물내로 도입된 삽입유전자의 정보를 이용한 검정방법이 도입되었으며, 또한 도입유전자의 발현된 단백질을 분석하기 위하여 정성 및 정량을 위한 면역학적 방법이 도입되었다. 본 총설에서는 국내 외적으로 개발된 콩, 옥수수, 카놀라, 면화 등의 GM식물에 적용된 multiplex PCR, real-time PCR 방법과 최신 개발 중인 microarray, 나노기술 등을 활용한 방법들을 조사하였다. Since the first commercial GM plant, the FlavrSavr tomato, authorized in 1994, more than 140 GM plants were authorized for marketing globally. For the authorization and labelling of GM plants, the detection methods for genes introduced and proteins expressed in GM plants were developed qualitatively and quantitatively. This review presented the detection methods, conventional PCR, multiplex PCR and real-time PCR, for soybean, maize, canola and cotton as the dominant GM plants. Also, microarray assay and nanotechnology as new approaches for detection methods for GM plants were investigated.
