Nano-sized gadolinium-doped ceria (GDC)/nickel particle-dispersed $La_ySr_{1-y}Ti_{1-x}Fe_xO_3$ (LSFTO)-based composite solid oxide fuel cell anodes were fabricated by an infiltration method and the effects of the GDC/Ni nanoparticles on the anode polarization resistance and cell performance were investigated in terms of the infiltration time and nickel content. The anodic polarization resistance of the LSFTO anode was significantly enhanced by GDC and/or Ni infiltration and it decreased with increasing infiltration time and Ni content, respectively. It is believed that the observed phenomena are associated with enhancement of the ionic conductivity and catalytic activity in the nanocomposite anodes by the addition of GDC and Ni. Power densities of cells with the LSFTO and LSFTO-GDC/Ni nanocomposite anodes were 150 and $300mW/cm^2$ at $800^{\circ}C$, respectively.

이 논문은 지난 수십년 동안 군사시설보호구역으로 지정된 수원비행장 주변의 고도제한규제, 건축제한규제로 인한 다양한 사회갈등 유발에 따른 효과적인 대책마련 위해 갈등관리 요인분석을 실시하였다. 논문의 분석기준이 될 갈등관리 성공요인을 도출하여, 도출된 성공요인(합의안의 정당성 요인, 갈등관리과정의 효율성 요인, 갈등당사자의 만족도 요인, 이해관계자 간 관계성 요인, 합의안의 지속성 요인, 그리고 합의안의 합리성 요인)을 주요 분석요인으로 하여 수원비행장 소음피해규제와 비행안전규제의 현황과 실태에 적용ㆍ분석하였다. The objective of this paper is to suggest effective resolution to the conflicts over Suwon Airport regulations. The airport has been protected as a military facility for the last few decades with regulations such as altitude and construction on the surrounding areas. This has caused various social conflicts. To come up with effective resolution, the paper first identifies conflict management success factors which are justification of the agreement, efficiency of conflict management process, satisfaction of the stake holders, relationship between the stake holders, continuity of the agreement, and rationality of the agreement. These factors are then applied in analyzing the current status and impact of Suwon Airport noise pollution and flight safety regulations.

The potential candidates for IT-SOFCs cathode materials, $Ba_{0.5}Sr_{0.5}Co_{0.8}Fe_{0.2}O_{3-{\delta}}$ (BSCF) and $La_{0.6}Ba_{0.4}Co_{0.2}Fe_{0.8}O_{3-{\delta}}$ (LBCF) powders, were synthesized by a EDTA-citrate combined method from $Sr(NO_3)_2$, $Ba(NO_3)_2$, $La(NO_3)_3{\cdot}6H_2O$, $Co(NO_3)_2{\cdot}6H_2O$, $Fe(NO_3)_3{\cdot}9H_2O$, citric acid and $EDTA-NH_3$. The cathode performance of symmetrical electrochemical cells consisting of BSCF-GDC or LBCF-GDC composite electrodes and a GDC electrolyte was investigated using by AC impedance spectroscopy at the temperature range of 500 to $700^{\circ}C$. It was found that a single phase perovskite could be successfully synthesized when the precursor is heated at $850^{\circ}C$ for 2 h. Due to thermal expansion mismatch between BSCF and GDC, the composite cathodes with lower GDC content than 45 wt% were peeled off from the GDC electrolyte and their electrode polarization resistance was estimated to be high. The thermal expansion coefficient of BSCF-GDC composites was decreased with increasing the GDC content and the electrode peeling off did not occur in BSCF-45 and 55 wt% GDC composites. BSCF-45 wt% GDC composite electrode showed the lowest area specific resistances (ASR) of 0.15 and $0.04{\Omega}{\cdot}cm^2$ at 600 and $700^{\circ}C$, respectively. On the other hand, LBCF-GDC composite cathodes showed higher ASR than the BSCF-45 and 55 wt% GDC and their cathode performance were decreased with the GDC content.

공공조직들은 목표가 모호하고, 다양하며, 정확히 측정하기 어렵다는 특징을 가지고 있다. 민간 기업의 목표가 이윤추구라면, 공공조직은 조직목표 차원에서 공공선(公共善), 공공성과 같은 행정가치를 추구한다. 이러한 공공조직의 특수성을 바탕으로 공･사 간 리더십 이론의 차별화가 이루어질 필요성이 제기되면서, ‘공공 리더십’이 등장하였다. 이에 본 연구에서는 전문가 델파이 분석을 통해 한국형 공공 리더십을 도출하였다. 결론적으로, 공공 리더십은 거래적 리더십 (상황적 보상, 규정 및 절차에 의한 관리), 변혁적 리더십(비전 제시, 영감 및 동기부여, 지적자 극, 맞춤형 배려), 서번트 리더십(공감, 소통, 집사 정신, 권한위임), 윤리적 리더십(윤리의식, 규범적 관리, 공공선 추구), 협력적 리더십(자원 확보 및 공유, 이해관계자 설득, 수평적 신뢰 구축), 진성 리더십(자기조절, 균형적 시각)으로 구성되었다. Public organizations have characteristics such as, ambiguous, diverse, and difficult to measure accurately. when it comes to the goal of private organization it pursues profit, while public organizations pursue administrative values such as public good and public value at the level of organizational goals. As the need to differentiate between public and private leadership theories based on the distinct characteristics of public organization, the conecept of “public leadership” was emerged. Therefore, in this study, we verified style public leadership under the Korean public sector circumstances through Delphi analysis. In doing so, public leadership was designated trtransaction, transformation, servant, ethical, collaborate, and authentic leadership
