The present study aims to analyze the extent of the use of STS contents in the areas of 'Evolution of Life' and 'Health of Humanity and Scientific Technology' in 'Science' textbooks and to determine whether they meet the goals of the curriculum revised in 2009. The analysis of the 7 types of textbooks according to the STS topics areas indicated big differences between textbooks as little as 16.67% and as much as 58.33%. Also, among the topics associated with STS, 'Space Development and National Defense' and 'Environmental Problems' were not included. In the STS activity areas, the areas of 'Structured Debate,' 'Interpretation of Data,' 'Research and Investigation' showed great frequency. On the other hand, the STS activity areas of 'Field Activities,' 'Problem-solving and Decision-making,' 'Role Playing,' 'Simulation,' 'Case Study,' and 'Research Design' showed small frequency. Analysis of the STS contents for each area indicated 67.57% for the contents relevant to 'the applicability of science' accounting for the largest part whereas 'Understanding of Occupations related to Science' accounted for 1.63%, showing a great difference in their frequency. Seven standards except 'the applicability of science' were included each contents beyond 10% or less than 10% proportion. The STS contents included in the life science area of the 7 types of convergence-style 'Science' textbooks for the high-school accounted for an average of 20.75%, from as little as 12.35% to as much as 26.90%, depending on the publishes.

Many researchers are studying brain activity to using functional Magnetic Resonance Imaging (fMRI), Time Resolved Spectroscopy(TRS), Electroencephalography(EEG), and etc. They are used detection of seizures or epilepsy and deception detection in the main. In this paper, we focus on emotion recognition by recording brain waves. We specially use fMRI, TRS, and EEG for measuring brain activity Researchers are experimenting brain waves to get only a measuring apparatus or to use both fMRI and EEG. This paper is measured that we take images of fMRI and TRS about brain activity as human emotions and then we take data of EEG signals. Especially, we focus on EEG signals analysis. We analyze not only original features in brain waves but also transferred features to classify into five sections as frequency. And we eliminate low frequency from 0.2 to 4Hz for EEG artifacts elimination.

The purpose of this study is to examine the influence of argumentation for elementary students' scientific writing. Using nine subjects that were comprised of scientific situations and social scientific situations, this study was applied to four 5th grade students utilizing argumentation and scientific writing. The students' scientific writing and argumentation were collected and analyzed based on three domains of scientific writing: scientific thinking, logic, and creativity. The results from this study are as follows. First, the various contents of argumentation positively affected all of the scientific writing domains in post-argumentation scientific writing. Second, the contents of argumentation appeared in the post-argumentation scientific writing as three different forms: 1) Each individual's scientific concepts, claims, and ideas, which were newly mentioned in the process of argumentation, were expressed, 2) Their classmates' claims, grounds and ideas, which were discussed in the process of argumentation, were expressed through internalization, and 3) Expanded ideas, new claims and inferences based on the argumentation were expressed.

In order to obtain data for developing an ideal science curriculum. four kinds of General Science textbooks based on the 6th curriculum were analyzed. Particularly inquiry activities were analyzed by Scientific Inquiry Evaluation Inventory(SIEI). The results are as follows: 1) The average number of inquiry activities in four kinds of textbooks is 115.5. And the number in each textbook is very diverse: textbook A contains 94 inquiry activities, textbook B 147. textbook C 100 and textbook D 121. 2) As for the number of inquiry activity scopes in four kinds of textbook. observation comes to 22, experiment 117, interpreting data 196, investigation 64, discussion 51, classification 4 and prediction 8. And then the conceptional inquiry activity is about 2.3 times as many as the inquiry experiment. 3) According to the analysis of each inquiry task by SIEI. textbook A has 268, textbook B 328, textbook C 207 and textbook D 304. 4) In the analysis of the structure of inquiry activity, the evaluation of the competition and cooperation scale shows more emphasis on common tasks. no pooled results(87.1 %). The discussion scale mostly consists of activities without discussion required among students(83.5%). The evaluation of openness scale shows more emphasis on activities with problems, procedures and answers presented(58.3%). In the evaluation of inquiry scope scale, the inquiry scope scale mostly has the activities to demonstrate or verify the contents of the text(66.9%). 5) As for the analysis of inquiry activities as a whole. The inquiry pyramid in four kinds of General Science textbooks shows the type I that emphasizes the inquiry activities in low level such as gathering and organizing data. The inquiry index in four kinds of textbooks is average 47.8, shows very high level (above 35).

Purpose: This research was a descriptive study of nursing activities observed in nursing simulation during a senior nursing student practicum. Content and frequencies of nursing activities during the simulation practice were identified. Methods: Thirty-six episodes of pediatric nursing simulation were videotaped. Both verbalizations and descriptions of nonverbal behaviors were recorded from the videotapes. The data were coded and analyzed. The coded nursing activities were evaluated for frequency and purpose of interaction. Results: Average time per simulation episodes was 27 minutes and ranged from 3.30 to 32.54 minutes. Nursing activities in these simulation episodes included nursing assessments such as vital sign measurement, associated symptom assessment, and check of patient condition, nursing interventions such as medication, tepid water massage, fluid therapy, provision of oxygen, suctioning, hyperglycemia and hypoglycemia management, communication such as parent education, procedure guidance, and communication among providers. Activities in assessment were most frequent, and among them, vital sign measurement and check of patient condition were more frequent than others. Conclusion: Students showed enhanced nursing activities such as more frequent nursing assessment, communication and interventions in their simulation experience. Therefore simulation experience can be considered as one strategies to provide nursing students with better and more intense practicum experience.

본 논문에서는 웨이브릿 영역에서의 영역 분류와 대역간 예측 및 선택적 벡터 양자화를 이용한 다분광 화상테이타 압축 기법을 제안하였다. 이 방법에서는 각 대역을 웨이브릿 변환 후, 각 대역의 기저밴드의 대역별 특성을 이용하여 영역 분류를 행하였다. 그리고, 다른 대역과 해상도가 동일하고 공간적 분산이 작으며 분광적 상관성이 큰 기준대역 (reference channel)을 결정한 뒤, 이를 영역별 스칼라 및 분류별 가변 벡터 양자화를 행하여 부호화 하였다. 또한 기준대역과의 대역간 상관성이 큰 대역들에 대해서는 영역별 대역간 예측을 행한 후, 활동도가 높은 블록에 대해서만 선택적 벡터 양자화로 부호화를 행하였다. 이때, 활동도가 높은 블록들의 위치정보는 기준대역으로부터 얻어지는 임계치 지도 (threshold map; THMAP)를 이용하였다. 즉, 제안한 방법에서는 각 대역에 대해 웨이브릿 영역에서의 영역 분류 후 영역별 대역간 예측을 행함으로써 다분광 화상데이타에 존재하는 대역간 중복성을 제거하고 선택적 벡터 양자화를 행함으로써 대역내 중복성을 효과적으로 제거하여 압축효율을 향상시킨다. 실제 원격 센싱된 인공위성 화상데이타에 대한 실험을 통하여 제안한 기법의 부호화 효율이 기존의 기법에 비하여 우수함을 확인하였다.

Current discussions on productive aging are going towards the direction to sustain a social productivity and lessen a social burden, and this becomes distinct as it gives a strong value to the activity and independence of older people. This study highlights complex situations of productive activities in the group of older people by analyzing the survey of Among the productive activities of older people, two areas of activities - paid labor and social support - were interpreted differently according to their economic stability, spontaneity and family relations. This difference becomes more remarkable in the analysis on life satisfaction of older people. In paid work, which is the most common productive activity, there was a big difference in life satisfaction between those who work spontaneously and those who work inevitably to make a living. And in the comparison of life satisfaction for those who participate in homemaking and care working according to their economic situations and family relations, those who were unsatisfied with family relations showed lower life satisfaction.
