  • This study aims at analyzing the relationship between team characteristic and innovation performance. The mediating effect of creative climate on the team characteristic and innovation performance is also measured. Based upon literature review, individual creative characteristics, team diversity, team cohesion, task characteristics are presented as antecedents of team characteristic. Creative climate affects the creative behavior and innovative performance. Creative climate is measured as the Team Climate Inventory (TCI) proposed by Anderson & West (1998) including goal, participative-autonomy and innovative-support. Data were collected from 186 survey responses (54 Teams) out of total 462 (69 teams) from the R&D department of a major ICT firm in Korea. Empirical results show the diversity, cohesion, job characteristic, individual creative characteristic have a positive effect on the creative climate and innovation performance. The participative-autonomy climate factor appears to mediate the relationship between team characteristic (diversity, cohesion, job and individual characteristics) and innovation performance. However, the mediating effects of goals and innovative-support factors were not significant statistically. It was confirmed that the organization can contribute to improve the team innovation performance by facilitating a autonomy and participative climate as well as fostering the team characteristic.

  • As the temperature has changed by climate change, changes in its own characteristic values of the chemical substance or the movement and distribution of chemicals take place in accordance with the changes of hydrological and meteorological phenomena. Depending on the impact of climate change on the chemical behavior, it is necessary to understand and predict quantitative changes in the dynamics of the environment of pollutants due to climate change in order to predict in advance the occurrence of environmental disasters, and minimize the impact on the life and the environment after the incident. In this study, we have analysed and compared chemical fate models validated by previous studies in terms of model configuration, application size and input/output factors. The potential models applicable to municipal and industrial areas were selected on the basis of characteristic of each model, availability of input parameters and consideration for climate change, identified the problems, and then presented an approach to improve applicability.

  • 사과 및 배의 재배적지 구분을 토양환경정보시스템을 통한 토양조건에 의한 재배적지값과 국립원예특작과학원에서 제작한 미래 상세 전자기후도 제공 시스템을 통한 기후조건에 의한 재배적지값을 최대저해인자법을 이용하여 통합된 적지 구분을 하였다. 사과 및 배 모두에서 통합된 적지구분은 토양의 적지 구분의 패턴과 상당히 유사하였다. 기후조건에 의거한 구분도에 비해서 토양조건에 의한 구분도가 전체적으로 상대적으로 적지의 등급이 낮은 것이 그 이유로 여겨진다. 토양조건에 있어서 적지등급을 결정하는 최종구간 값들이 상당히 높게 형성되어 있어 전체적으로 등급이 낮게 결정된 것으로 사료되어 최종구간값들의 정확도에 대한 보정이 요구된다. 최대저해인자법은 이렇게 하나의 인자의 값들이 저평가되었을 때, 그 값들이 대표화되어 전체적으로 등급의 영향을 미치는 단점을 가지고 있다고 여겨진다. 세부적 인자에 대한 최대저해인자법의 적용 및 계층분석방법(Analytic Hierarchy Process, AHP) 등의 다양한 방법론과 토양 및 기후의 세부적 요소에 근거한 실제 단위면적 당 생산량 혹은 경제적 수익 등의 실제 현장관측값들과의 보정을 통해 재배적지구분의 정확도 및 정보의 실효성을 높일 수 있을 것으로 사료된다.

  • Recently, the climate change due to global warming, heat wave, heavy snow etc., is rapidly progressing all over the world. This kind of climate change is judged to be affecting a lot in construction industry which has characteristic of outdoor industry. Therefore this study, to prevent death disaster occurring by climate elements at construction site, quantitatively analyzed real condition of death disaster on construction site and suggests basic management direction which to be conducted on the site.

  • This study attempts to facilitate climate change adaptation in conservation area by spatial planning of climate adaptation zone for endangered species. Spatial area is South Korea and select leopard cat (Prionailurus bengalensis) as a target species of this study. In order to specify the climate adaptation zone, firstly, Maximum entropy method (Maxent) was used to identify suitable habitat, and then core habitat was selected for leopard cat. Secondly, land use resistance index was evaluated and least cost distance was analyzed for target species. In this step we choose dispersal capacity of leopard cat to reflect species ecological characteristic. Finally, climate adaptation zone is described and adaptation measures are suggested. The presented approach could be generalized for application into conservation planning and restoration process. Furthermore, spatial planning of climate adaptation zone could increase heterogeneity of habitat and improve adaptive capacity of species and habitat itself.

  • To reduce the energy consumption of HVAC system in buildings, thermally activated building system(TABS) has been applied to low energy building because of energy efficient performance and reduction of peak load. DOAS coupled with a parallel sensible cooling could be promising because TABS handles sensible heat load only. The purpose of this study was to evaluate the indoor thermal environment and cooling operation characteristic of TABS with dedicated outdoor air system(DOAS) in Korea climate. Indoor thermal environment and operation characteristic of TABS integrated with DOAS are investigated at different TABS operation schedules and climate conditions by simulation tests. The result shows that the DOAS is more suitable for hot and humid climates. And also it show that the potential of intermittent operation of TABS.

  • The NLCCA has been applied to analyze the East Asia sea surface temperature (SST) and Korea monthly precipitation, where the eight leading PCs of the SST and the eight PCs of the precipitation during 1973-2007 were inputs to an NLCCA model. The first NLCCA mode is plotted in the PC spaces of the Korea precipitation and the world SST present a curve linking the nonlinear relationship between the first three leading PCs of Korea precipitation and world SST forthright. The correlation coefficient between canonical variate time series u and v is 0.8538 for the first NLCCA mode. And there are some areas' climate variability have higher relationship with Korea precipitation, especially focus on the north of East Sea' climate variability have represented the higher canonical correlation with Korea precipitation, with the correlation coefficient is 0.871 and 0.838. Likewise in Korea, most stations display similarly uniform distributing characteristic and less difference, in particular the inshore stations have display identical distributing characteristic. In correlation variables' scores, the fluctuation and variation trend are also seasonal oscillation with high frequency.

  • 본 논문에서는 배전 시스템을 구성하는 기기들에 대한 설치 현황자료와 고장 자료 및 전국 지점을 대상으로 한 설문조사 자료를 이용하여 기후별 고장률을 예측하였다. 같은 종류의 배전 설비라 하더라도 그 설비가 설치되어 있는 기후 상태에 따라서 고장률은 다르게 나타날 수 있다. 그러므로 배전기기의 고장률을 설비관리나 최적 투자 계획의 운용에 사용하기 위해서는 대상 설비가 설치된 기후 특성을 고려해야 하며 이를 위해 기후 특성을 고려한 고장률 예측이 요구된다고 할 수 있다. 기후특성분석을 위하여 한국전력공사의 전국지점을 대상으로 기후 특성(호우, 낙뢰, 강풍, 해일, 특징 없음)으로 구분하여 설문조사를 실시하였고 기후 특성에 따른 영향도를 분석하였고 고장률 추정 알고리즘을 제안하였다.
