There are a lot of games which have good benefits in the game genre such as serious game. In this paper we implement an serious game for increasing intensive power by calculating the index of the intensive power based on EEG signal. First we explain the definition of the EEG and the classification of the brainwaves and we depict the method for increasing the intensive power. Then we apply the index of the intensive power to the game production to train the intensive power. At last we make an experiment on the effect of an game which increases the intensive power and the analysis shows the increase of the intensive power.

In this paper, we investigate the achievable sum rate and energy efficiency of downlink massive multiple-input multiple-output antenna systems with zero-forcing precoding, by taking into account the randomness of user locations. Specifically, we propose two types of non-uniform user distributions, namely, center-intensive user distribution and edge-intensive user distribution. Based on these user distributions, we derive novel tight lower and upper bounds on the average sum rate. In addition, the impact of user distributions on the optimal number of users maximizing the sum rate is characterized. Moreover, by adopting a realistic power consumption model which accounts for the transmit power, circuit power and signal processing power, the energy efficiency of the system is studied. In particular, closed-form solutions for the key system parameters, such as the number of antennas and the optimal transmit signal-to-noise ratio maximizing the energy efficiency, are obtained. The findings of the paper suggest that user distribution has a significant impact on the system performance: for instance, the highest average sum rate is achieved with the center-intensive user distribution, while the lowest average sum rate is obtained with the edge-intensive user distribution. Also, more users can be served with the center-intensive user distribution.

Coordinating operation between large-scale wind power and thermal units in multiple time scale is an important problem to keep power balance, especially for the power grids mainly made up of large coal-fired units. The paper proposes a novel operation mode of multi-scale unit commitment (abbr. UC) that includes mid-term UC and day-ahead UC, which can take full advantage of insufficient flexibility and improve wind power accommodation. First, we introduce the concepts of multi-scale UC and then illustrate the benefits of introducing mid-term UC to the wind-coal intensive grid. The paper then formulates the mid-term UC model, proposes operation performance indices and validates the optimal operation mode by simulation cases. Compared with day-ahead UC only, the multi-scale UC mode could reduce the total generation cost and improve the wind power net benefit by decreasing the coal-fired units' on/off operation. The simulation results also show that the maximum total generation benefit should be pursued rather than the wind power utilization rate in wind-coal intensive system.

Purpose: This study was done to define nursing behavior in neonatal intensive care units so as to estimate resource-based relative value-. Method: Participating in this study were 292 nurses in neonatal intensive care units. The study surveyed physical and mental labor, stress and time involved in nursing work. Tool used in this study was a nursing labor per relative value tool. For analyzes, the relative value of each nursing behavior was calculated, where the mean value of the three components, labor intensity and component-by-component explanatory power were in percentage terms. Results: 1. Nursing behaviors in neonatal intensive care unit were classified and defined at three levels: 5 main domains, 17 mid-domains, and 42 small domains. 2. The per component explanatory power of intensity involved in nursing labor showed physical effort to be 32.45%, mental 32.86%, and stress 34.69%. 3. The reliability of nursing labor factors was very strong, Cronbach's alpha value of 0.96. Conclusion: In this research, which is a first in defining nursing behavior in neonatal intensive care units, individual nursing behavior were broken down using resource-based relative value for nursing cost, and each nursing behavior was successfully translated to a numerical value.

Purpose: This study was conducted to investigate the factors influencing the competence in intensive and critical care nursing of senior nursing students. Methods: A descriptive survey was used to examine the factors that influence competence in intensive and critical care nursing. The data were collected using self-administered questionnaires; 237 senior nursing students were asked about general characteristics, critical thinking, communication competence, self-esteem, self-resilience, and self-leadership. Results: Multiple regression analysis indicated that self-leadership, self-esteem, and confidence in intensive care unit practice predicted the competence in intensive and critical care nursing (37.8% of explanatory power). Critical thinking, communication competence, and self-resilience were not shown to be significant predictors of, but were positively correlated with, the competence in intensive and critical care nursing. Conclusion: Based on the results, it is suggested that self-leadership, self-esteem, and confidence in intensive care unit practice should be considered in nursing education in order to improve nursing students' level of competence in intensive and critical care nursing.

Technology-intensive industries can be used as a major growth engine for resource poor country in the territories. For example, in the case of Korea, nuclear power and radiation technology industry was highly developed, and it was possible to obtain national interests such as solving energy problems within the country and exporting nuclear power plants. On the other hand, there are cases where national damage is caused by erroneous governmental policy-making on technology-intensive sectors. In this study, we analyzed cases of misguided governmental policy-making for technology-intensive industry and three factors were identified. And we tried to develop a rational policy-making model using three types of allison's model in combination. The results of this study are expected to be useful for rational governmental policy-making processes for technology-intensive industries.

Purpose : The aims of this study was to provide basic data to enhance the professional self-concept of nurses in intensive care unit and identify the relationship between job stress, working bullying, self-efficacy and professional self-concept and identify the factors influencing professional self-concept in intensive care unit nurses. Methods : This study was conducted from June to August, 2018 at five general hospitals over 500 beds. Structured questionnaire were completed by 120 nurses who had agreed to understand and participate in the study. The collected data were analyzed using the SPSS win 24.0 program. Results : Factors affecting the professional self-concept of the subjects were self-efficacy, working bullying, unsatisfaction and satisfaction of nursing job satisfaction, age. The explanatory power of these variables on professional self-concept was 55.1%. Conclusion : The self-efficacy, working bullying, nursing job satisfaction, and age of the intensive care unit nurses were identified as the major factors influencing the professional self-concept. Therefore, it is necessary to develop and apply an educational program to improve self-efficacy and nursing job satisfaction and reduce working bullying, which are influencing factors of professional self-concept of intensive care unit nurse.
