Corporations look for their competitiveness in many different areas, and one of them is customer call center, which provides professional, special service to the customers. The importance and the value of realization of customer satisfaction at each call center have become significant as it plays a leading role and is responsible for customer recreation and follow-up services. This study held in-depth interviews with 3 groups of professional call representatives (categorized by experience) from popular property and life insurance companies in Korea who operate in and outbound calls. Three variables, emotional quotient, organizational citizenship behavior (OCB), and IT utilization skill, were selected and it was observed how these variables affect the job performance of in and outbound call center representatives. The importance of the relationship between the variables and the key factors in the future direction of improvement of the call center representative organization was analyzed. Emotional quotient refers to the ability to recognize and use the emotion of oneself and others. It was considered it would be effective in enhancing the counseling ability of call center representatives, This study identifies the effect of emotional quotient on job performance and organizational citizenship behavior, which is defined as actions outside of normative roles in the organization. Also, the study aims to prove the effect of emotional quotient on the rapidly developing IT utilization ability in relation to job performance. As a result, it was found that service career (3 months, 3 years, 10 years) had a significant effect on the key factors that affect the organization-emotional quotient, IT utilization skill, and OCB. Especially for OCB, it was considered relatively less important to the new employees, while it greatly affected the job performance, rate of settlement, and sustainment of the working life for those with longer experience. Also, the result of the interview for each variable differed by the service career. Emotional quotient, IT utilization skill, and OCB were close connection for the representatives with longer experience than for those with shorter experience. And the level of intimacy of their relationship with job performance was in proportion to the years of service. Thus, to secure stability for the call center representatives and enhance their job performance continually, the importance of emotional quotient and IT utilization skill shall be reflected in the operation process actively. In particular, in order to lead a organization with outstanding culture, a management system shall apply OCB from the recruitment process.

Objectives: This study aims to supplement the limitations of the preliminary study and expand the use of the Child-Adolescent Functional Assessment Scale by providing standardized T-scores for measuring function in different areas, as well as guidelines for their interpretation. Methods: The Child-Adolescent Functional Assessment Scale and Korean-Child Behavior Checklist were administered to a total of 623 individuals, including 467 parents of emotionally and behaviorally disturbed elementary school students, 45 parents of emotionally and behaviorally disturbed middle school adolescents and 111 parents of elementary school students with developmental disorders, as well as to a control group consisting of 186 parents of mainstream elementary school children in the Seoul metropolitan area. Results: In contrast to the preliminary study, the emotional domain was disassociated into two factors, negative affect and emotion regulation, and the coefficient of determination for misconduct was increased significantly. Also, the overall reliability and validity of the Child-Adolescent Functional Assessment Scale were similar to those in the preliminary study, and the item structure was consistent. This study provides standardized T-scores of function in different areas based on the revised scale, and provides guidelines for their interpretation. Conclusion: The Child-Adolescent Functional Assessment Scale can assist the Child Global Assessment in Functioning in providing the information necessary for case management and treatment planning by comparing the impairment severity in each area of functioning, and also determining changes in behavior and function after treatment interventions. On the other hand, this scale has yet to clearly distinguish between rebellious behavior and misconduct. Further research is necessary to provide standards for more diverse age groups and for its utilization.

The controllability and stability of power systems can be increased by Flexible AC Transmission Devices (FACTs). One of the FACTs devices is Interline Power-Flow Controller (IPFC) by which the voltage stability, dynamic stability and transient stability of power systems can be improved. In the present paper, the convenient operation and control of IPFC for transient stability improvement are considered. Considering that the system's Lyapunov energy function is a relevant tool to study the stability affair. IPFC energy function optimization has been used in order to access the maximum of transient stability margin. In order to control IPFC, a Brain Emotional Learning Based Intelligent Controller (BELBIC) and PI controller have been used. The utilization of the new controller is based on the emotion-processing mechanism in the brain and is essentially an action selection, which is based on sensory inputs and emotional cues. This intelligent control is based on the limbic system of the mammalian brain. Simulation confirms the ability of BELBIC controller compared with conventional PI controller. The designing results have been studied by the simulation of a single-machine system with infinite bus (SMIB) and another standard 9-buses system (Anderson and Fouad, 1977).
