본 연구는 가족치료 상담자의 의사소통 능력향상을 위해 훈츠누어셔의 대화문법론을 기반으로 가족치료 전체 회기에 나타나는 상담자와 내담자 간 의사소통의 전형적인 구조인 ‘대화연속체 원형’을 기술하고 설명하는 것을 목적으로 한다. 먼저 선행연구를 통하여 가족상담의 과정단계를 초기, 중기와 종결단계로 분류하고, 각 과정단계의 부분적 기능단계를 분위기 조성단계, 가족사정단계, 인식변화 유도단계, 변화체험 확인단계, 종결단계로 나누어 대화연속체 원형을 구축하였다. 그리고 2명의 상담자와 30명의 내담자가 참여한 실제 가족치료 대화를 분석하여 각 기능단계에서 나타나는 대화연속체 원형을 설명하였다. 본 연구를 통해 구축된 대화원형은 일반적인 가족치료의 대화구조를 분석하는 틀로써 상담의 목적에 맞게 가족치료를 구조화시키고 상담자들의 효과적인 의사소통 능력을 평가하는데 사용될 수 있다. This study investigated dialog sequence prototype that was the structure of communication, which could be shown in family counseling conversation between therapists and clients. The study was intended to review the process stages of family counseling through literature review, and divided functional phases into 'atmosphere formation phase', 'family evaluation phase', 'persuasion phase of cognitive change', 'confirmation phase of change experience', and 'termination phase'. The study selected two family therapists and 30 clients for research objects. They allowed data collections for the study after the explanation about the research objects. The transcribers were trained by the consent of transcription, which used particular symbol for verbal and nonverbal contents in conversation. The transcribed data were analyzed by dialog grammar, one of the linguistic dialog analysis method developed by Hundsnurscher(1994). This study described and explained dialog sequence prototype that displayed in conversation between family therapist and client through the total sessions in family therapy. The study found three types of dialog sequence prototype in 'atmosphere formation phase', eight types in 'family evaluation phase', nine types in 'persuasion phase of cognitive change', eight types in 'confirmation phase of change experience', and eight types of 'termination phase'. Even if the dialog sequence prototype mentioned above cannot be applied to the process of family therapy at its face value, these findings may contribute to beginners in counseling and graduate students majoring family therapy to do practice in counseling. The research has a limitation in which the study investigated dialog sequence prototype of conversation in two persons. Future research needs to include dialog sequence prototype of conversation among more than three persons. Specifically, when a family therapist do family counseling,he/she treats more than three family members as usual. Therefore, the researchers hope that future study investigates dialog sequence prototype between therapist and client, client and client, among therapist, client and other family members.

Servers that provide clouding should be prepared for data usage changes. In case of web traffic, if the power consumption of the base unit generates heat and it can not be cooled down smoothly, the clouding system will be out of the operating temperature range of the IT equipment. The efficient power consumption of the data center requires CPU technology that maintains the performance of the underlying equipment at high temperatures and technology that efficiently cools the underlying equipment. The local cooling in the enclosure rack, which is cooled inside the rack, without draining the heat generated by the server"s heat from the server rack, is the most efficient way to reduce power consumption. This paper describes server cooling system using variable liquid pump control which absorbs hot air generated by the server heat and then discharges the cooled air to the front of the server rack to discharge heat out of the rack. The server cooling unit uses PWM(Pulse width modulation) fan control to keep the cooling air temperature constant, and saves power energy by using stable cooling load and efficient power usage. By using the power consumption information of PDU(Power distribution unit) that supplies power to the server to effectively control the amount of cooling, stable operation of the cloud server equipment is ensured by fast and accurate cooling. This study controls the rotation of EEV(Electric expansion valve) and liquid pump with variable refrigerant flow control.

The permanent magnet machines have the advantages of high efficiency and power density, features very improtant for air-borne applications with their requiement of no external dc supply for rotor excitation, in addition, a very lower synchronous reactance thus making it a stiff source of power with a higher steady state and more transient capability than ist counterpart, the wound rotor type. In this paper, The permanent magnet synchronous machine is taken as a power source in the variable speed constant frequency power conversion scheme with converter-inverter system. All digital routines are excuted in the sampling time of 100 micro second by a DSP Board (TMS320c25) with A/D converters, which is detect the load current, capacitor current and DC link voltage at a sudden load change and to compute the predicted current. In one sampling interval, two optimal space voltage vectors as well as tow zero voltage vectors are employed so that the capacitor current may follow the reference. As a result, sinusoidal output constant voltage is obtained while swiching frequency is constant, and experimental results are presented, which shows the effectiveness of the proposed control method.
