Majority problem and synchronization problem on cellular automata(CA) are hard to solve, since they are global problems while CA operate on local information. This paper proposes a way to find state transition rules of these problems. The rules of CA are represented as CMR(conditionally matching rules) and evolutionary algorithms are applied to find rules. We find many solution rules to these problems, compared the results with the previous studies, and demonstrated the effectiveness of CMR on one-dimensional cellular automata.

This study is based on Freud's psychoanalysis and intends to deal with the actual psychoanalytic counseling applied to it. In particular, I would like to study the counseling process and counseling techniques. The research results are as follows. The counseling process goes through four stages: initiation, transfer development, training, and transfer resolution as follows after selecting a client and constructing a counseling situation. In the beginning phase, the client listens to important past histories. In the metastasis development stage, it is from the time when metastasis appears. The training phase is the phase in which the client's insight is translated into real life to bring about change. The transfer resolution stage is the period when transfer analysis and interpretation are completed. Counseling techniques include free association, empathy, resistance, transference and countertransference, and interpretation. Free association is a key technique in psychoanalytic therapy and plays an important role in maintaining the analytical framework. Empathy is the ability of the therapist to identify herself with the client and the ability of the therapist to convey the empathic experience to the client itself is a key mechanism for change. Resistance refers to any behavior in which the client does not cooperate with counseling. Transference and countertransference are the main techniques of psychoanalysis. This is because the psychoanalyst induces and resolves the transference of the client during the treatment process. Interpretation refers to the technique of responding verbally in order to understand the needs, meanings, and motives hidden behind the client's thoughts, feelings, and actions. In conclusion, the counseling process of psychoanalytic counseling refers to the purpose of effective counseling by selecting a client and constructing a counseling situation. In addition, the principles of psychoanalysis in counseling techniques are applied to treatment procedures that vary according to the nature of the case, and can be variably applied while treating the same client.

본 논문에서는 자유 선택 신호 전이 그래프와 비동기 유한 상태기로 기술된 회로 명세로부터 직접 속도 독립 회로를 합성하는 시스템에 대해 기술한다. 기존의 상태 그래프 기반의 합성 시스템은 상태의 수가 지수승으로 증가할 수 있기 때문에 큰 규모의 회로에 대해서는 합성에 실패할 수 있다는 문제점을 가지고 있다. 이를 해결하기 위해 여러 직접 합성 방법들이 제안되었는데, 본 논문의 합성 시스템은 마크드 그래프 분할 방법과 임시 전이의 사용을 허용함으로써 합성할 수 있는 회로의 범위를 넓혔다. 기존의 벤치마크 회로에 대한 실험결과 본 합성 시스템은 기존의 상태 그래프 기반의 합성 시스템에 비하여 현저하게 수행 속도를 단축시킬 수 있었고 기존의 직접 합성 시스템에 비하여 보다 확장된 그리고 보다 실용적인 회로 명세를 처리할 수 있었다.

본 논문은 ATM(Abstract Timed Machine)에 대해서 기술한다. ATM 은 임무 위급 시스템과 같은 실시간 시스템을 명세, 분석 및 검증할 수 있는 정형 기법이다. ATM 은 모드(mode), 전이(transition), 포트(port)로 구성된다. 모드는 머신의 압축된 상태를 의미하고 전이는 모드와 모드 사이의 변화를 말한다. 포트는 ATM 들 사이의 상호작용을 위한 진입을 나타내기 위한 것이다. ATM 은 소프트웨어 순환 공학을 위해 디자인 되었다. ATM은 재/역공학적 측면에서 계산 이론과 더불어 기존의 실시간 시스템의 소스코드에 대한 디지안 및 환경 정보를 나타낸다. 본 논문은 병렬성, 병렬적으로 동작하는 엔터티들 사이의 제어 정보이 흐름, ATM 타입과 클래스로부터의 인스턴스, 비/동기적 이벤트, 포트와 이벤트 타입, 포트의 타입, 통신, 입/출력, 예외처리, 시간에 관한 요구사항, 다수를 대상으로 하는 통신 주기적 작업등과 같은 ATM의 여러 개념을 기술하고 이러한 속성들을 Producer-Buffer-Consumer 예제로 살펴본다.

13C2H2분자의 1.54949$\mu$m 회전-진동 전이 흡스선을 이용하여 DFB LD의 발전주파수를 안정화 시킴으로써 이를 주파수대욕 광 다중통신(OFDM)의 표준주파수를 광동기 신호로 활용하는 방안에 대하여 연구하였다. 본 연구에서는 DFB LD의 발진주파수의 변화에 따른 기체 Cell의 투과한 빛의 세기의 변화를 연산 처리하여 이를 안정화 Loop에 대한 error 신호로 사용하여 줌으로써 MHz 이내에 주파수 안정도를 갖는 광 동기신호를 구성하였다. 이러한 안정화 방법을 이용하여 이제까지 제안된 다른 방법에 비하여 광학계통과 광신호처리 과정을 크게 단순화 된, 또한 동작중 자체 진단 및 자동복구 기능을 갖춘 이상적인 신호를 구성하였다.

In a large number of words and the continued speech recognition system using a phoneme as teh recognition unit, it is necessary to segment processing. In this paper, a normalized AMDF new method. The suggested parameter represents a degree of sharpness at valley point. This method can detect the speech segment between the steady state and transient region to the continued speech without a prior information of speech signal.

Introducing algorithm and programming education to the middle school 'Information' curriculum is appropriate to develop higher thinking skills like problem solving ability and creativity that is the most important ability to the people living in the knowledge and information society. But to providing reduced algorithm and programming contents of higher education increase the cognitive burden on the students in the concrete operational period who is not yet reached to the formal operational period, and moreover transfering principles and strategies learned in the algorithm to the programming for the problem solving is difficult. For this study, student's developmental characteristics in the concrete operational period among cognitive developmental periods was considered, and FAAP(First-Algorithm After-Programming) learning model which can transfer algorithm to programming was developed, and finally the effectiveness of learning motivation and achievement to the concrete operational period's students was verified. Results of the tests showed that learning motivation and achievement of the concrete operational period's students that learned FAAP model were different significantly.

In OFDM-based Full Duplex Relays (FDR) with Decode and Forward (DF) scheme, an interference cancellation technique in the frequency domain is more efficient than the one in the time domain. However, an Inter-Symbol Interference (ISI) and Inter-Carrier Interference (ICI) may occur due to the timing mismatch between the feedback interference signal and the desired signal from Base Station (BS) when the feedback interference cancellation and demodulation are performed in the frequency domain. In this paper, the effects of timing mismatch on the synchronous type and asynchronous type of OFDM-based FDR are analyzed for uplink and downlink cases. Then, synchronization procedure and methods for reducing ISI and ICI in OFDM-based FDR with frequency-domain feedback interference canceller are proposed and verified by computer simulation.

In this paper, there is summarized the validation of ground test results through the telemetry acquired during on-orbit initial activation on solar-array drive assembly(SDA) of GK2A launched at Dec-5, 2018. Especially, the decision logic of SDA initial position and the compensation logic are validated and confirmed. The SDA initial position is needed when GK2A enter to geostationary orbit from transfer orbit and the compensation logic is for the accumulated position error due to the open-loop control. Up to now, it is normal operating. Also the periodic offset between the geostationary orbit and Sun position is found that it is not checked on design phase, and then the proper threshold value is applied.

This paper is brought to asses the training effect of KS-QFD boot camp for the companies in the early growth stage. In particular, the focus of research falls on measuring transfer intension of the participants from the early stage companies older than three years old, motivating effect of applying knowledges acquired from KS-QFD training camp into their real business case. KS-QFD program is presented to help company in the early stage companies over three years old of boosting up their sales volume more than 5 times than now for the next 18 months by this training. The training program of KS-QFD is ultimately to design more practical and helpful program to real business and spread out. The research establish model by setting the learner readiness and perceived content validity by doing training design as independent variables, self-efficacy of learner as mediating variable, and transfer intension as dependant variable. Research results shows the following outcomes. First, learner readiness does not have directly effect on transfer intension under keeping statistical significance. But as the parameter of self-efficacy, it has perfect mediating effect. Second, research proves that perceived content validity have directly impact on learning transfer intension of mediating by self-efficacy partially. This research contributes on proving that learning by doing KS-QFD boot camp enable the participants to build up their self-efficacy and lead to enhance transfer intension. In more steps, the research validates that KS-QFD training camp have delivered very practical and helpful on-site knowledge to the participants.
