The purpose in this paper is to provide the theoretical framework of characteristics of programming thinking processes in computational literacy education. That is, we developed the theoretical framework through analyzing novices' cognitive thinking processes, applied it to the real situation about computational literacy problem-solving processes and defined characteristics of the processes. For this purpose, we tried to analyze characteristics of programming thinking processes of novices by using think-aloud method. Also we developed the programming process code about novices' cognitive processes and programming processes, and analyzed the process that novice faced and overcame programming barriers by using qualitative research tool, Nvivo. As a result, we found what characteristics of programming problem-solving processes were and how novices used the thinking skill in the process. This study contributes to understand programming problem-solving processes and provides the criterion to analyze the processes scientifically.

의도와 관심의 실현을 위하여, 언어 행동을 주도하는 '의식'이 사고와 언어를 연결할 때에 드러내는 특성과 기능 일부를 밝히기 위해, <실용 논리> 수업 시간에 녹화한 한 대학생의 토론 첫 부분 내용을 Chafe의 '억양 단위' 분석법에 따라 분석한 결과, 억양의 단위는 평균 1.8초, 9.5음절로 구성되며, 언어와 사고는, 물처럼 흐르는 것이 아니라, 억양 단위로 끈어진 토막들이 의식에 의해 연결되면서 '관심점'의 내용이 전개되고 있는 것임을 발견하였다. 각 억양 단위 속에는 뚜렷하게 발음하는 하나 정도의 '초점'과, 그렇지 않은'주변' 내용과 형식으로 구성됨을 확인하고, 초점들을 서로 이으면 결국, 이어진 말 중심 내용이 드러남도 발견하였다. 한국어와 일본어 억양 단위는 주어＋동사 형식을 갖추지 않은 예가 60％와 67.4％이므로, 주어＋동사 모형은 언어와 사고 전개 모형의 한 예에 불과하다고 해석한다. 각 단위들의 연결 면에는 문제가 있음도 발견하였다.

식품의 관능검사는 인간의 의식과 식품간의 반응결과를 객관적으로 나타내는 방법으로 수치, 언어적 묘사, 도표 등의 표현법을 사용하고 있으며 검사 요원들 간의 오차를 발생한다. 이 오차를 줄이기 위하여 통계 및 심리학적으로 접근하여 해결을 시도해 오고 있으며 오차를 심리적 잡음 (psychological noise)이라고 주장되고 있다. 식품의 기호도는 감각신경세포에서 전기적 신호로 전환되어 뇌에 전달되고 의식의 분석과 해석을 거쳐 얻어지는 것이므로 전기적 신호처리가 포함된다. 그러나 현재의 관능검사 방법들은 시간의 함수관계를 중시하고 있지 않다. 감각신경의 신호 전달체계의 유사성을 바탕으로 관능검사과정에 시간함수를 도인하는 개념이 요구된다. 시간을 개입하는 방법론으로 의식과 식품간의 일어나는 순차적 또는 병열적 행동과 의식체계를 분석하고 시간인자의 중요성을 부각시켰다. 시간함수의 도입방법으로 관능영향인자 표의 구성하고 bar-code를 생성하는 프로그램과 파형곡선으로 전환하는 개념을 제안하였다.

The purpose of this study was to investigate the effects of learning achievement by comparing project approach group and the control group on the unit of growing flowers and vegetables in practical arts education. For this purpose, the experimental study on the unit of growing flowers and vegetables was achieved with 63 students(5th grade 2 classes) in S elementary school. The project approach model (Chung, Sung-bong) was applied to the experimental group, and the traditional model to the control group. To verify the effects of each class, nonequivalent control group post test-only design was applied 10 times. The SPSSWIN(ver 12. 0. 1) was used for analyzing the frequency and t-tests. The results of this study were as follows ; First, there was significant effect of learning achievement(cognitive domain) in the project approach groups. In addition, learning achievement of the experimental group has been showed significant difference about intellectual function and ability but not about knowledge. Second, there was significant effect of learning achievement(psychomotor domain) in the project approach groups. In other words, there has been showed significant difference in basic skill and integrated skill for growing flowers and vegetables but not in elemental skill for planting. Third, as the post test, there existed significant effect(affective domain) in the project approach groups. In other words, there was a meaningful difference in acceptance, value, belief, actualization but not in interest. Based on these results, It is believed that the project approach model in the unit of 'growing flowers and vegetables' is more effective than the traditional learning method in learning achievement of learners' cognitive, psychomotor and affective domain.

Introduction: It has been proposed that narcolepsy and REM sleep behavior disorder (RBD) have overlapped symptom profile and pathophysiology. This study was aimed at measuring and comparing changes in EEG frequency band of REM sleep in narcolepsy and RBD, applying EEG spectral analysis method. Methods: Nine patients diagnosed as narcolepsy and the same number of RBD patients were studied. Spectral analysis of the REM sleep EEG was performed in each patient on 9 epochs selected evenly from the first, second, and third REM periods. Then, we compared frequency band percentages of REM sleep EEG in narcolepsy and RBD. Results: Narcolepsy patients had significantly higher delta frequency ratio than RBD ones (p=0.00). In alpha and beta2 frequency bands, RBD patients showed higher percentage than narcolepsy ones. Slow wave sleep was more prevalent in narcolepsy patients. But, no difference of REM sleep percentage was found between the two groups (p=0.93). Conclusion: Higher delta frequency ratio in REM sleep of narcolepsy patients than RBD ones reflects that sleep-promoting mechanism is more dominant in narcolepsy than in RBD.

The purpose of this study was to examine the effect of twitter influenctials on users' willingness on express opinions. Based on the spiral of silence and corrective action hypothesis, the contradictory hypotheses were drawn. The online expeiment was conducted to verify which hypothesis is valid. Participant were assigned to the four experimenatal conditons: a famous influential's twit which agrees with the issue; a famous influential's twit which disagrees with the issue; an ordinary influential's twit to agree with the issue; an ordinary influential's twit to disagree with the issue. Results showed that opinion congruency with a twitter influential did not influence participants' willingness to express opinion online and offline, but the interaction effect with the type of influentials was found. Opinion dissonance with an ordinary tiwtterian increased willingness to express opinion. The findings suggest that twitter influentials, particulary an ordinary influentials with differnet opinions, can motivate users to express their own opinion.
