This research examines the effects of organizational learning and network involvement, as well as many contextual factors, on power generation businesses' innovation capability and operational success in Vietnam. This research also aims to attest to the moderating roles of top management support and company age, and firm possession type in the power generation industry. This study applied the exploratory factor analysis (EFA) and PLS-SEM approach for data analysis. In this research, we have tested hypotheses with data collected from 132 top managers and other key personnel from power generation companies in Vietnam. The results also attest to the moderating role of top management support on the two relationships between organizational learning - innovation capability and network involvement - innovation capability. Another important finding is that the company age has a negative impact on operational performance but shows a positive moderating role in the relationship between innovation capability and operational performance. This study highlights the central roles of organizational learning and innovation capability in impacting the organizational performance of power generation companies. These companies play a key role in supporting the development of industries in practice. This research also emphasizes the moderating roles of top management support and company age and possession type in practice.

도로는 일관성 있는 선형으로 안전하게 주행할 수 있도록 설계되어야 하며. 안전성 향상을 위해 적절한 주행속도로 주행할 수 있는 환경이 제공되어야 한다 적절한 도로환경을 제공하기 위하여 설계 시 정확한 주행속도의 반영은 필수적이므로, 이를 예측할 수 있는 주행속도 예측모형이 필요하다고 판단된다. 이에 본 연구에서는 주행속도 예측모형 구축을 위해 영동고속도로를 대상으로 주행속도에 영향을 미치는 요인을 크게 선형요소, 교통운영특성 요소로 분류하였다. 분류한 요인을 중심으로 평면직선, 평면곡선구간 그리고 종단곡선구간의 각 구간별로 상관분석을 통하여 주행속도에 영향을 미치는 요인을 선정하였다 선정한 요인들을 대상으로 다중회귀모형을 이용하여 주행속도예측모형을 구축 및 검증 결과, 본 연구의 주행속도 예측모형이 통계적으로 모두 적합한 것으로 나타났다. 본 연구는 평면 및 종단선형요소를 동시에 반영하여 국내 도로 실정에 맞는 주행속도 예측모형을 개발하였다는 데에 그 의의가 있다. 그러나 분석자료가 영동고속도로로 한정되어 전국을 대표할 수 없으므로 향후 전국을 대상으로 도로 선형요소를 바탕으로 대표성을 지닐 수 있는 연구가 필요하다고 판단된다.

The reliability of power system components can be affected by a numbers of factors such as the health level of components, external environment and operation environment of power systems. These factors also affect the electrical parameters of power system components for example the thermal capacity of a transmission element. The relationship of component reliability and power system is, therefore, a complex nonlinear function related to the above-mentioned factors. Traditional approaches for reliability assessment of power systems do not take the influence of these factors into account. The assessment results could not, therefore, reflect the short-term trend of the system reliability performance considering the influence of the key factors and provide the system dispatchers with enough information to make decent operational decisions. This paper discusses some of these important operational issues from the perspective of power system reliability. The discussions include operational reliability of power systems, reliability influence models for main performance parameters of components, time-varying reliability models of components, and a reliability assessment algorithm for power system operations considering the time-varying characteristic of various parameters. The significance of these discussions and applications of the proposed techniques are illustrated by case study results using the IEEE-RTS.

To reduce energy consumption in wastewater treatment plants (WWTPs), renewable energy applications such as small hydropower, solar energy, and wind energy are popular. However, it should be noticed that energy originated from operation of wastewater treatment process can be reduced through optimized operation based on analysis of factors affecting energy. In this research, the relationship to the various operational variables and influent factors was explored using correlation analysis and decision tree algorithm. Due to the non-linear characteristics of the process, it was difficult to find clear linear patterns through correlation analysis. However, decision tree algorithm showed its usefulness in uncovering hidden patterns that consume energy. As operational factors, influent flowrate, the amount of aeration, nitrate recycling pumping rate, and sludge wasting pumping rate were selected as important factors. For environmental factors associated with influent compositions and removal rate, BOD and T-N removal rate were selected as significant factors.

Purpose - This paper examines the effects of host country's non-economic factors on foreign affiliate's financial and operational performance. Design/Methodology - Using Korean-owned foreign affiliate-level data, we employ various measures that represent host country's non-economic factors and examine their effects on foreign affiliate's performance. We further investigate the effects of local top managers and local middle managers on the impact of country's non-economic factors on foreign affiliate's performance. Findings - We find that local top managers are effective in increasing foreign affiliate's financial performance by dealing with institutional and cultural factors, particularly in high-income countries, while local middle managers are effective in increasing affiliate's operational performance by responding to the changes in doing business factors, particularly in low-income countries. Originality/value - Considering that most of previous FDI studies focus on examining host country's economic factors on firm's FDI decision, our findings suggest that country's non-economic factors are strongly associated with actual business performance of foreign affiliates.
