차세대 에너지로 연료전지가 각광을 받고 있는 현재, 세계 각국에서는 연료전지의 상용화를 위해 노력하고 있다. 그러나 촉매분야에서 백금계 촉매의 사용량의 문제에 따른 매장량 한계점과 귀금속이라는 문제점이 존재하기 때문에 이에 대하여 대책강구가 필요한 시점이다. 이에 백금 촉매의 활성을 증대하고자 나노 크기의 제어 연구가 진행되고 있다. 또한, 촉매의 구조적인 면에 따라 촉매의 활성이 달라지는 점을 착안하여 백금계의 나노 형상 조절 연구와 백금계 촉매를 대체할 비백금계의 촉매 개발 연구가 활발히 진행되어지고 있다. 이에 본 연구는 백금계 촉매 중 Pd을 polyol process에 의한 나노 형상 조절을 통하여 단위 질량당(or 단위 부피당) 촉매의 활성을 높이고자 하였다. Polyol process에서는 환원제, 계면활성제, 온도, 시간, 기타 첨가제에 따라 나노 형상이 다르게 조절되는데, 이에 계면활성제로 PVP를 사용하고, 반응속도 및 형상조절을 위해 다양한 첨가제를 이용하여 polygonal Pd NPs을 형성하였다. 본 나노 형상 조절에서는 첨가제와 온도가 가장 큰 영향을 미치는 요인으로 착안하여 그에 따른 polygoanl Pd NPs의 사이즈 조절을 통해 전기화학 특성이 차이의 연구에 중점을 두었다. 이에 따라 나노 형상 조절이 된 Pd촉매를 이용하여 상용화된 촉매(Pd/C(XC-72R))에 비하여 전기화학적인 특성의 차이와 Pd 촉매의 촉매적 특성의 효과를 보고자 한다.

본 연구는 인접한 저수지 간의 연계운영을 통해 홍수조절능력을 제고시키기 위한 저수용량 공유기법 개발의 일환으로서 안동댐과 임하댐의 병렬저수지 시스템을 연구대상유역으로 선정하였다. 홍수조절에 의한 병렬저수지의 연계운영기법으로서 홍수시 임하댐의 저수량을 안동댐으로 전환시켜 임하댐의 홍수조절능력을 제고시키고 안동댐의 저수량을 확보하여 용수공급능력을 제고시킬 수 있는 방법을 연구하였다. 임하댐의 유입량 중 안동댐으로 전환되는 유량비를 최적화계수 a로 두고 재현기간별로 유량전환비를 산정한 결과 최적화계수로 제안한 유량전환비 a는 재현기간 T=50년일 때 $a_{50}=0.310$, T=80년일 때 $a_{80}=0.185$, T=100년일 때 $a_{100}=0.130$, T=150년일 때 $a_{150}=0.035$로 산정되었으며, T=200년일때는 유량전환에 의한 홍수조절 효과가 없음을 알 수 있었다. 이러한 계산결과는 홍수규모가 클 경우에 안동댐 저수량(위) 증가로 인하여 임하댐의 유량전환비가 감소하기 때문임을 알 수 있었으며, 그 유량전환비가 거의 0이 될 경우는 홍수규모가 재현기간 T=200년 빈도 이상에서 나타나고 있음을 알 수 있었다. 이로 인한 홍수조절효과는 임하댐의 경우 재현기간 T=50년 일 때 4.1%, T=80년일 때 2.8%, T=100년일 때 2.1% 및 T=150년일 때 0.7%로 증가한 것으로 나타났으며, 안동댐의 경우 재현기간 T=50년일 때 14.4%, T=80년일 때 8.6%, T=100년일 때 6.0% 및 T=150년일 때 1.6%로 증가한 것으로 분석되었다.

The purpose of this study was to examine the mediating effects of adaptive-maladaptive cognitive emotion regulation strategies in relationship between communication competence and problem-solving capacity. Subjects were 189 male collegiate athletes. The results were as follows: Their communication competence had a positive influence on their problem-solving capacity, and their adaptive emotion regulation strategies had a partial mediating effect on the relationship between communication competence and problem-solving capacity. But the maladaptive emotion regulation strategy did not have a statistically significant relationship with communication competence or problem-solving capacity. This result suggests that the communication competence and customized adaptive emotion regulation strategies are necessary to improve the problem-solving capacity of collegiate athletes.

This study aimed to identify the moderating effect of public health service utilization rate between public health resources and community mental health. The subjects included 144 local communities, from the data of 6th Community Health Plan and the 2015 Community Health Survey. Public health resources were measured by public health budget, public mental health budget and public mental health personnel; and mental health was measured by rate of perceived stress, rate of depressive mood and suicide rate. The hierarchical regression analysis was used to identify the moderating effects. The results were as followed. First, the effect of public mental health budget on rate of depressive mood was moderated by public health service utilization rate. Second, the effect of public mental health personnel on rate of depressive mood was moderated by public health service utilization rate. Third, the effect of public mental health personnel on suicide rate was also moderated by public health service utilization rate. Fourth, the effect of public health resources on mental health differed between the groups with high and low public health service utilization rate. In improving community mental health, the measures to improve the public health service utilization rate should be considered to ensure that reinforcing public health resources leads to the improvement of community mental health.

This study analyzed the moderating effect according to school levels in the structural relationship between stressful interpersonal relationships at work and rumination in teachers' depression. For this study, a research model was formed based on theoretical understandings and a literature review. The researchers surveyed 811 teachers at primary and secondary schools to measure scales of depression, rumination, and stress in interpersonal relationships at work. Primary education and secondary education were the grouping variables for the school levels, and the collected data was analyzed using multi-group structural equation modeling. Also, to affirm equivalence between the two models, the data was investigated using the constrained model of measurement equivalence. The research results verified the equivalence between the two models and the moderating effect by comparing the path coefficients of the two models on the assumption of equivalence constraint. As a result, the moderating effect according to school levels was revealed on the path from stressful interpersonal relationships at work to depression. Grounded on this analysis, stress in interpersonal relationships at work mediates the impact of rumination in teachers' depression. In addition, the research revealed that the moderating effects on stressful interpersonal relationships at work varied according to school level, and the moderating effect of stress in interpersonal relationships at work affected middle school teachers but not primary school teachers.
