Recent wireless communication trends have emphasized the importance of energy-efficient transmission. In this paper, link adaptation with machine learning mechanism for maximum energy efficiency in multiple-input multiple-output orthogonal frequency division multiplexing(MIMO-OFDM) wireless system is considered. For reflecting frequency-selective MIMO-OFDM channels, two-dimensional capacity(2D-CAP) feature space is proposed. In addition, machine-learning-based bit and power adaptation(ML-BPA) algorithm that performs classification-based link adaptation is presented. Simulation results show that 2D-CAP feature space can represent channel conditions accurately and bring noticeable improvement in link adaptation performance. Compared with other feature spaces, including ordered postprocessing signal-to-noise ratio(ordSNR) feature space, 2D-CAP has distinguished advantages in either efficiency performance or computational complexity.

In the mobile Internet, users generally work with handheld devices with limited computing power and small screens. Their access conditions also change frequently. In this paper, we present a novel method supporting intelligent content adaptation to better suit handheld devices. The underpinning is a unit of information (UOI)-based content adaptation method, which automatically detects semantic relationships among the components of Web contents and then reorganizes page layout to fit handheld devices based on identified UOIs. Experimental results demonstrate that our method enables more sensitive content adaptation.

Purpose: The purpose of this study was to determine the degree of undergraduate nursing student adaptation to college life and investigate the factors that influenced that adaptation. Methods: First-year (undergraduate) students attending three nursing colleges were surveyed from November 24 through December 5, 2014; and data from 206 respondents were analyzed. For data analysis, multiple regression analysis was performed using the SPSS WIN 18.0 program. Results: The findings showed that age (p=.002), emotional intelligence (p<.001), and self-efficacy (p<.001) were significant variables that influenced first-year undergraduate nursing student adaptation to college life. Undergraduate nursing student adaptation was explained by self-efficacy (${\beta}=.327$, p<.001), emotional intelligence (${\beta}=.222$, p=.001), satisfaction with education in their academic major (${\beta}=-.217$, p<.001), and academic achievement (${\beta}=.136$, p=.018); and, the explanatory power of these variables was 41.2%. Conclusion: To facilitate undergraduate nursing student adaptation to college life prior to clinical practice, developing and apply programs to improve self-efficacy, emotional intelligence, satisfaction with education in their major, and academic achievement is deemed necessary.

Purpose: This study was to investigate the effects of communication styles and stress coping on college adaptation in nursing students. Methods: The data was collected by questionnaires from 180 nursing students in a university in Gyeongsan, Korea. The data were analyzed with the SPSS/Win 23.0 program, using descriptive statistics, independent t-test, and multiple logistic regression. Results: A positive correlation was found for college adaptation with a functional communication pattern such as leveling stance (r=.36, p<.001) and stress coping (r=.39, p<.001). With more using of functional communication and with higher level of active coping of stress coping, nursing students appeared to more successfully adaptation to college life. It was also found that an explanatory power for college adaptation of these factors was 29.8% (F=20.01, p<.001). Conclusion: The study results indicate that it is necessary to develop various programs that can improve effective communication and active coping of stress coping of nursing students in order to enhance the adaptation process to college life.

Purpose: The purpose of this study was to identify the role adaptation process experienced by executive directors of nursing department of general hospitals. Methods: Data were collected from 9 executive nursing directors though in-depth interviews about their experiences. The main question was "How do you describe your experience of the process of role adaptation as an executive nursing director?" Qualitative data from field and transcribed notes were analyzed using Strauss & Corbin's grounded theory methodology. Results: The core category of experience of the process of role adaptation as an executive nursing director was identified as "entering the center with pushing and pulling". The participants used five interactional strategies; 'maintaining modest attitudes', 'inquiring about trends of popular feeling', 'making each person a faithful follower', 'collecting & displaying power', 'leading with initiative'. The consequences of role adaptation in executive nursing directors were 'coexisting with others', 'immersing in one's new role with dedication', and 'having capacity for high tolerance'. The types of role adaptations of executive directors in nursing department were friendly type, propulsive type, accommodating type. Conclusion: The results of this study produced useful information for executive nursing directors on designing a self-managerial program to enhance role adaptation based on interactional strategies.

This paper explores the efficacy on enforcing empowerment for the beginner special education teachers' adaptation of teaching life. Empowerment is widespread public concern regarding the role of the teacher in decision made in the operation of schools. Therefore what is discussed to be definition, a central component and strategies of empowerment based upon the through literature review. Empowerment is defined in terms of teachers power to participate in decision making about teaching and learning condition, especially is related to disabilities. And Empowerment has six components, decision making, professional growth, status, self-efficacy, autonomy, and impact. When novice teachers in special education utilize self-empowerment strategy, they have the opportunities for greater status and increasing power.Finally, empowerment is at the heart of special education teachers' adaptation of teaching life. It is suggested that follow-up studies should be conducted to develop indicator for assessing what teachers in special education perceived their empowerment in overall work. Also higher education program must address this issue in pre-service training of administrators and teachers in special education.

Purpose: This study examined the effects of self-leadership and critical thinking disposition on adaptation to college among nursing students. Methods: A descriptive study was conducted with 325 nursing students using a self-report questionnaire. Data were analyzed using a t-test, one way ANOVA, $Scheff{\dot{e}}$ test, Pearson correlation coefficients, and stepwise multiple regression analysis with SPSS 20.0. Results: The mean score of college adaptation was 3.22. Significant predictor variables affecting adaptation to college were satisfaction in major (${\ss}=.45$, p<.001), behavior-focused strategies (${\ss}=.16$, p<.001), leadership level (${\ss}=.15$, p=.003), and grade (${\ss}=.11$, p=.016). The explanation power of this regression model was 32.2% and was statistically significant (F=64.60, p<.001). Conclusion: The results of this study indicated that an effective college adaptation program should be developed by including improvement of satisfaction in major, behavior-focused strategies, and leadership level.

We propose a nonlinear feedback controller that can control the induction motors with high dynamic performance by means of decoupling of motor speed and rotor flux. The nonlinear feedback controller needs the information on some motor parameters. Among them, rotor resistance varies greatly with machine temperature. A new recursive adaptation algorithm for rotor resistance which can be applied to our nonlinear feedback controller is also presented in this paper. The recursive adaptation algorithm makes the estimated value of rotor resistance track its real value. Some simulation results show that the adaptation algorithm for rotor resistance is robust against the variation of stator resistance and mutual inductance. In addition, it is computationally simple and has small estimation errors. To demonstrate the practical significance of our results, we present some experimental results.
