The purpose of this study is to analyze the effect of public deliberation with opinion polls of Floating Photovoltaic (FPV) Project in Saemangum. As a result of the analysis, the understanding of the issue as an educational effect has increased, and the positive position on the FPV has also increased significantly from 39% to 68%. In particular, it can be seen that the neutral group, which accounted for 41.5%, moved 28% to positive or negative positions after deliberation. Among the environmental, safety, economic, and social sectors of the FPV, the provision of information related to environmental impacts was found to have the greatest influence on the change in participants’ perceptions. In addition, participants’ evaluation score of the deliberation process was high. It indicates that citizens have a positive opinion about the deliberation poll method. The results of this analysis suggest that it is necessary to provide accurate information and various participation systems so that citizens can have discussions when promoting renewable energy projects that are difficult for citizens to understand, such as FPV. 이 연구는 공론화의 숙의 효과를 살펴보기 위하여 군산시에서 개최한 새만금 군산시 수상태양광 사업 시민토론회 자료를 통계적으로 분석하였다. 분석 결과, 교육적 효과로서 사안에 대한 이해도가 높아졌으며, 수상태양광 사업에 대한 긍정적 입장도 사전 39%에서 사후 68%로 크게 증가하였다. 특히, 사업 시행에 대해 41.5%를 차지하던 중립 의견은 토론회 이후 긍·부정적 입장으로 28%가 이동하여 이러한 숙의적 공론화가 의견 형성에 영향을 미쳤음을 알 수 있다. 수상태양광 사업의 환경·안전·경제·사회 부문 중 환경적 영향과 관련한 정보 제공이 참여자의 인식 변화에 가장 큰 영향을 미친 것으로 나타났다. 또한, 시민참여단의 토론회 평가 점수가 높게 나타나 숙의적 여론조사 방식에 대해 시민들이 긍정적으로 생각하고 있음을 알 수 있다. 이러한 분석 결과는 수상태양광 등 시민들이 잘 알기 어려운 재생에너지 사업을 추진할 때 정확한 정보를 제공하고 시민들이 논의할 수 있도록 다양한 참여 제도를 마련하는 것이 필요함을 시사한다.

Gunsan has been promoting a large-scale floating solar project in the form of resident participation, whose target areas include Okseo-myeon near the power plant site and Hoehyeon-myeon near the site of the power transmission line. Factors affecting residents’ acceptance were analyzed through surveys and in-depth interviews in this study. Through a factor analysis, variables related to social/economic, environmental/safety, and acceptance were derived. As a result of the regression analysis, the more they thought that the project would be economically and socially helpful, the higher the acceptance of the project. And the more they thought that there would be a negative impact in terms of environment and safety, the lower the acceptance. As a result of comparing the two regions through the independent sample T-test, it was found that the residents of Okseo-myeon thought that the floating solar project would be socially and economically helpful, with fewer environmental and safety concerns and, therefore, the project acceptance was relatively higher. The residents of Okseo-myeon emphasized the need to share benefits of the project with the local community in that they did not receive adequate compensation in the past Saemangeum reclamation project, and the floating solar project could cause damage to their fishing activities. Residents of Hoehyeon-myeon experienced severe conflicts with operators during the transmission line project in the past, and expressed strong opposition to the construction of additional transmission lines because of high safety risk. In common, the residents of both local areas thought that it is important to share specific information about the damage and benefits that could be caused by the project. These study findings suggest that project promoters need to work to share information and communicate with local residents based on understanding of their historical experience and socioeconomic conditions. 군산시는 대규모 수상태양광 사업을 주민참여형으로 추진하고 있는데, 관련 대상 지역은 발전소 부지 인근 옥서면과 연계 송전선로 부지 인근 회현면이다. 이 연구에서는 설문조사와 심층면접을 통해 주민들의 수용성에 영향을 미치는 요인을 분석하였다. 요인분석을 통해 사회·경제, 환경·안전, 수용성에 관한 변수를 도출할 수 있었다. 회귀분석 결과 경제·사회적으로 도움이 된다고 생각할수록 사업 수용성이 높고, 환경·안전 측면에서 부정적인 영향이 있다고 생각할수록 수용성이 낮게 나타났다. 독립표본 T검정을 통해 두 지역을 비교한 결과 회현면 주민들에 비해 옥서면 주민들이 수상태양광 사업에 대해 사회·경제적으로 도움이 된다고 생각하고, 환경·안전성 측면의 우려가 더 적으며, 사업 수용성이 더 높은 것으로 나타났다. 옥서면 주민들은 과거 새만금간척 사업 과정에서 보상을 제대로 받지 못했고, 수상태양광 사업으로 어업 피해가 있을 수 있다는 우려로 인해 지역 사회에 이익이 공유될 필요가 있음을 강조했다. 회현면 주민들은 과거 송전선로 사업 과정에서 사업자와의 극심한 갈등을 경험했으며, 안전 위험이 크다는 이유로 추가적인 송전선로 건설을 강하게 반대하는 입장을 나타냈다. 두 지역 주민들은 공통적으로 사업으로 인해 발생할 수 있는 피해와 이익에 관한 구체적인 정보 공유가 중요하다고 생각했다. 이러한 연구 결과는 설비 입지 예정지 주민들의 역사적 경험과 사회경제적 상황에 대한 이해를 기초로 사업자들이 주민들과 정보를 공유하고 소통하려는 노력이 필요함을 시사한다.

The mechanical properties and softness of electrospun polyvinylidene fluoride (PVDF) nanofibers was improved by the addition of a small amount of tributyl citrate (TBC) plasticizer to PVDF spinning solutions. The PVDF nanofibers containing TBC were prepared by electrospinning and subsequent calendering. The morphology, mechanical properties, and thermal properties of the electrospun PVDF nanofibers were investigated using Field Emission Scanning Electron Microscopy (FE-SEM), tensile test and DSC analysis. The results of the tensile experiment indicate that the PVDF nanofibers containing 5 wt% of TBC have three times better strength and six times higher elongation in the mechanical direction (MD) compared to those of pure PVDF nanofibers. Thus, the results indicate that PVDF nanofibers containing TBC have potential applications not only in the textile industry but also in the electrical and biomedical fields. Further, the excellent mechanical properties and softness of the eco-friendly nanofibers containing TBC plasticizer is useful for its commercialization.

Several offshore wind power conflicts occur due to the problems in which the site selection process led by privateoperators is improperly managed. To review the institutional improvement measures that solve this problem, domestic and foreigninstitutions and operational cases were comparatively analyzed, focusing on key actors from the multi-level governance perspective. First, the status of the site selection process in the Republic of Korea, major issues in stakeholder conflicts, and discussions on theplanned site system-related laws (draft) were reviewed. Next, the site selection process and relevant cases in Germany, theNetherlands, and Japan were analyzed. In all these countries, site selection is done by the central government. In Germany and theNetherlands, maritime-related ministries establish overall offshore wind power site plans and conduct strategic environmentalassessments for these plans. Futhermore, in the process of determining each individual site, extensive site investigation includingenvironmental assessments are conducted. This aspect needs to be supplemented in the discussion on the direction of institutionalimprovement in the Republic of Korea.

유정희,소윤미,황정원,도상환,김종수 대한마취통증의학회 2009 Anesthesia and pain medicine Vol.4 No.2

Background: Epidural analgesia provides effective pain control during labor. However, its influence on the course of delivery is controversial. The aim of this study was to assess the effect of epidural analgesia on the course of delivery and the perinatal outcome and to examine the changes of the cesarean delivery rates that are associated with epidural analgesia. Methods: Among 1,200 parturients who delivered in our hospital from 2003 to 2005, we obtained the demographic and obstetric data for 240 primiparous deliveries (120 women in the epidural group [group E] and 120 women in the nonepidural group [group N]). The duration of the active phase and the second and third stages of labor, the perinatal outcome and the incidence of emergency cesarean delivery were analyzed. Results: The duration of the second stage of labor was longer in group E (41 ± 23 min in group N vs. 49 ± 28 min in group E, P = 0.02). The incidences of cesarean delivery were similar between the two groups [15 (12.5%) in group N vs. 18 (15%) in group E, P = 0.6]. The incidences of fetal distress during the active phase of labor did not differ in both groups (48% vs. 41%, respectively, P = 0.4). The neonatal outcomes, including the birth weight, fetal heart rate deceleration or bradycardia during labor and the Apgar score, were similar between the two groups. Conclusions: We conclude that epidural labor analgesia does not seem to be associated with an increased incidence of cesarean delivery. In addition, epidural labor analgesia seems to have no adverse effect on the perinatal outcomes of primiparous women.

Poly(vinylidene fluoride) (PVDF) is a critical polymeric material used in the mass production and application of electrospun nanofibers, and is popular due to its excellent properties. However, electrospun PVDF nanofibers are very hydrophobic and possess low surface energies, limiting their broad application. In this work, we investigated practical methods for the hydrophobic surface modification of PVDF nanofibers using four techniques: radio-frequency (RF) and PIN-type atmospheric plasmas, planar inductively coupled plasma (ICP), and planar capacitively coupled plasma (CCP). The use of RF atmospheric plasma was ineffective under the experimental conditions used, while the PIN-type atmospheric plasma efficiently modified PVDF nanofiber surfaces locally. The application of planar CCP to PVDF nanofibers was more effective than planar ICP for the same experimental conditions. In particular, the water contact angles of samples treated with planar CCP for 600 s and 900 s were $25^{\circ}$ and $10^{\circ}$ respectively, and wettability improved. Analysis with FT-IR, XPS, and FE-SEM showed that the surface CF and CH hydrophobic groups were destroyed without damaging the PVDF nanofibers, and hydrophilic species such as C=O, OH, and COOH were formed. As a consequence, quantitative analysis of nanofiber chemical composition is necessary when treated by plasmas, providing insight into the correlation of specific property changes with processing conditions, and indicating precise research results and application examples.
