It is widely recommended that teachers should actively mediate students' engagement with tools such as manipulative materials. This paper is to help to parse classroom life so that both social and psychological aspects are accounted for and coordinated. Building on the theory of affordances from ecological psychology and the activity theory from sociocultural perspectives, the main strategy of this paper is to view manipulative materials as simultaneously participating in social and psychological activity systems. Within these activity systems it is charted how both mathematical affordances related to the structure of mathematical concepts and ecological affordances related to socially situated classroom practices need to be considered by teachers in effective mediation of mathematical manipulatives. This paper has three major sections. The first section develops a theoretical extension of Gibson's theory of affordances from natural to social environments. The second section introduces mathematical and ecological affordances using empirical data from a grade two elementary school classroom. The third section illustrates the need of coordinating the two affordances as embedded in different activity systems.

A growing body of evidence shows that most psychological traits are polygenic, that is they involve the action of many genes with small effects. However, the study of selection has disproportionately been on one or a few genes and their associated sweep signals (rapid and large changes in frequency). If our goal is to study the evolution of psychological variables, such as intelligence, we need a model that explains the evolution of phenotypes governed by many common genetic variants. This study illustrates simple statistical tools to detect signals of recent polygenic selection: a) ANOVA can be used to reveal significant deviation from random distribution of allele frequencies across racial groups. b) Principal component analysis can be used as a tool for finding a factor that represents the strength of recent selection on a phenotype and the underlying genetic variation. c) Method of correlated vectors: the correlation between genetic frequencies and the average phenotypes of different populations is computed; then, the resulting correlation coefficients are correlated with the corresponding alleles' genome-wide significance. This provides a measure of how selection acted on genes with higher signal to noise ratio. Another related test is that alleles with large frequency differences between populations should have a higher genome-wide significance value than alleles with small frequency differences. This paper fruitfully employs these tools and shows that common genetic variants exhibit subtle frequency shifts and that these shifts predict phenotypic differences across populations.

According to a study on the accident patterns of older people in 2006 by Korea Consumer Agency (CISS), the number of accidents of the elderly at home reached 486, and the figure has increased every year. As Korea is about to enter into the aged society, it is important to investigate the factors that cause an accident in the welfare facilities for the aged and establish the barrier-free construction standards. The accident influence factors include facility environmental, physical functional, socio demographic and socio psychological factors. In terms of the verification tools, there are Facility Evaluation Index, FIM, MMSE-K and General Feature. In terms of analysis method, in addition, there are real number, percentage, t-test, ANOVA and logistic regression. In conclusion, this paper attempts to reveal correlations among the accident influence factors using the Facility Evaluation Standards (115 items in total) for facility environmental factor, FIM (3 items) for physical functional factor, MMSE-K (6 items) for socio psychological factor and questionnaire (5 items) for socio demographic factor.

This research is a fundamental research to provide the foundation that psychological test can be utilized efficiently. It investigated and studied the reality of the psychological test used in elementary school, teacher's degrees of understanding and utilization of psychological test, requirements for improving the psychological test that is performed currently, and the direction of the testing tools that are required by elementary school. First, the main purpose of psychological test was different. The tests that were usually utilized in elementary schools were career inventory test and aptitude test, followed by personality test, learning test, creativity test and intelligence test in order. Second, it showed that teachers read the testing manual before carrying out the psychological test and understood it individually, the degree of understanding of T score showed to be the lowest. As a factor that hampered elementary school teacher's understanding of the psychological test, there was insufficiency of the teacher's professional knowledge, and it showed that the preparatory training for teachers about the tools of psychological test was necessary in order to improve this. Teacher's degree of utilization of psychological test showed to be lower than that of understanding. As a factor that influenced this kind of utilization by teachers, the lack of methodical understanding in afterwards guidance after the testing was the biggest factor. To increase the teacher's degree of utilization of psychological test, it was investigated that advice for more specific methods of guidance after the testing was necessary. Third, cross analysis was executed to find out if there was difference in the degree of understanding and utilization of psychological test according to whether a teacher completed the education course regarding counseling or not, and as a result, there was difference in the degree of understanding regarding some tests, but there was no difference found in the degree of utilization. Besides these, the point to be complemented in psychological test that was currently executed elementary schools and the direction of the testing tools that elementary schools require were investigated.

Objectives : The aim of this study is to review the instruments used to assess patient condition and the effects of Korean medical treatment for patients injured in traffic accidents in clinical studies in the Korean medical field published in South Korea. Methods : A literature study was performed, and clinical studies on patients injured in traffic accidents visiting Korean medical clinics or hospitals were examined. Data about chief complaints, tools used to assess either patients' condition or the effectiveness of Korean medical treatment, and time point of assessment were extracted. The studies were classified according to symptom. The use-frequency and the parent category of the assessment tools were also analyzed. Results : 78 studies were selected and classified into 5 categories based on the chief complaints, neck pain, lower back pain, headache, psychological symptoms and unspecified symptoms. Various scales were used to report the patient's pain severity, and functional or psychological status resulting from traffic accidents. Pain index, in particular VAS, was most frequently used and a few mechanical instruments and Korean medicinal assessment tools were mentioned. Conclusion : Most instruments used in Korean medicine clinical studies on patients injured in traffic accidents are self-reported tools. To assess both the patient's condition precisely and the effectiveness of Korean medical treatment on patients injured in traffic accidents, more appropriate and unified tools should be designed that consider pain, functional disability, psychological status and objective assessments measured by devices together.

Since the working machine generates an excessive loud noise as much as its use-purpose and dimension, those damages are occurring to the exposed workers such as unpleasant sense, stress and occupational hearing-impaired. Accordingly, as one of the measures for prevention such loud noise, various soundproof protection tools were developed. However, such soundproof protection tools were presented the physical measured value only, it is real state that the psychological study result with regard to the soundproof effect which the workers are actually feeling, is not existing. On such point of view, with the object on the typical earplugs and earcaps among the soundproof protection tools, this study has ever tried a subjective evaluation about the degree of soundproof effect through Psycho-acoustics experiment. It is considering that such study result could be utilized as the useful material when establishing the soundproof measure for the workers in the future.
