As the service industry develops, service quality, customer satisfaction, and human resource management are considered priorities in modern management to maintain a company's growth. Therefore, understanding the strategic importance of service marketing is an essential task for modern companies. This study examined the relationship between the internal service quality of employees in the organization and customer orientation through organizational effectiveness. In the case of an airline, a service can be defined as an interaction between an external customer and an internal customer service provider. This interaction significantly affects the behavior and attitude of the employees. Based on the results, empowerment has a significant influence on the internal service quality, but it has no significant effect on customer orientation. As the relationship between department and employees improved, the more confident staff showed an improved ability to perform their work. Therefore, it is important that the organizational structure and the reporting system are as concise and clear as possible to allow employees to accurately recognize the authorities and responsibilities assigned to them and have autonomy and discretion in the framework.

In order to facilitate the supply of gradually increasing power demand, it is also necessary to increase the number of power cables for power transmission as well as generation facilities. However, the expansion of electric power cables for supplying power to most urban areas requires a space for installation of additional cables, and the space for installing cables in domestic downtown areas is insufficient at present. The superconducting power cable, which can transmit more power with the same size, has emerged as an alternative to overcome the insufficient cable installation space. However, superconducting power cables, which have the advantage of large power transmission, have some losses in the AC (Alternating Current) system. Therefore, the design and analysis of AC losses are essential to introduce superconducting power cables in AC power transmission systems. In this paper, we analyze the AC loss of various superconducting power cables and consider the actual superconducting power cables and their application to the system. Although there is a theoretical calculation method of AC loss for single superconducting wire, it is not easy to calculate AC loss of superconducting power cable with large number. Therefore, the authors intend to analyze various kinds of superconducting power cable AC loss by using electromagnetic finite element analysis considering E-J (Electric field-Current density) characteristics of superconductivity. The analysis of the AC loss characteristics of the superconducting power cable will be an important factor in the design and development of the superconducting power cable to be applied to the actual system.

Wind energy is one of the rapidly developing renewable energies which is being developed and invested in response to climate change. As renewable energy policies and power plant installations are promoted, the supply of wind power in Korea is gradually expanding and attempts to accurately predict demand are expanding. In this paper, the ARIMA and ARIMAX models which are Time series techniques and the SVR, Random Forest and XGBoost models which are machine learning models were compared and analyzed to predict wind power generation in the Jeonnam and Gyeongbuk regions. Mean absolute error (MAE) and mean absolute percentage error (MAPE) were used as indicators to compare the predicted results of the model. After subtracting the hourly raw data from January 1, 2018 to October 24, 2020, the model was trained to predict wind power generation for 168 hours from October 25, 2020 to October 31, 2020. As a result of comparing the predictive power of the models, the Random Forest and XGBoost models showed the best performance in the order of Jeonnam and Gyeongbuk. In future research, we will try not only machine learning models but also forecasting wind power generation based on data mining techniques that have been actively researched recently.

The conflicts among nations surrounding international rivers are intensifying as worldwide water shortage is getting worse. The Mekong River is a representative trans-boundary river in Southeast Asia shared by six countries, China, Myanmar, Thailand, Laos, Cambodia, and Vietnam. As the economy grows, hydroelectric power has become a major power supply source to meet the increasing power demand of the these countries. However, the construction of dams on the Mekong River is controversial because hydroelectric power in the river upstream has a negative impact not only on the whole river ecosystem but also on residents' life around downstream, in particular. In order to understand the controversy arising from international rivers, it is necessary to take into account different positions of countries sharing it. However, studies on the position of a specific country to Mekong hydropower have been conducted mainly focusing on China and Laos. Therefore, this study tried to study the position of Cambodian government which is located downstream of the Mekong River and is likely to bear costs rather than to gain benefits from hydroelectric power generation. What is the attitude of the Cambodian government to the hydroelectric development of the upper Mekong and what is the reason for that? The study confirmed the Cambodian government's support for dam construction on the Mekong River. It also figured out influential factors on the formation of such a position as follows: 1) economic asymmetry with China, 2) power dependency and geographical asymmetry in Laos, and 3) importance of hydroelectric power in Cambodia.
