The main purpose of this study was to investigate the relationships of children's creativity to field independence-dependence cognitive style and demographic variables at age 5. The subjects for the present study were 86 five-year-old boys and girls selected from two kindergartens in Seoul and their parents, who replied to the questionnaire about demographic variables. Children were tested in groups, with the Torrance tests of Creative Thinking-Figural, and individually with the Preschool Embedded Figures Test. The data were analyzed by one way ANOVA, t-test, and Pearson's product-moment correlations. Children's fluency and originality in creativity showed significant positive correlations with field dependent-independent cognitive style. There were no significant differences in creativity according to sex. There were significant differences in field dependent-independent cognitive style according to sex. The score of field independent cognitive style of boys were significantly higher than those of girls. Children's creativity showed low correlations with demographic variables.

Since the superconductor type II with high critical current and high critical magnetic field was discovered in 1961, there were many studies on the superconducting coil for high field and highly homogeneous field. The graphical method and the numerical method by Newton Raphson technique have been studied as the method for design of homogeneous superconducting coil. It is comparatively easy to get a compensating coil for any given main coil by the above methods, but it is too laborious to get a general solution for main coil dimension. This paper studies the optimal design method for minimum volume of superconducting coil under certain central field and highly homogeneous field. The present method makes use of the nonlinear programming for optimization. The optimal solution of NMR superconducting coils by this method are demonstrated very well.

The purpose of this study was to investigate (1) children's field dependence by age and sex, (2) children's interpersonal problem solving ability by age, sex, and contextual factors, (3) children's interpersonal problem solving ability by field dependence. The subjects were 120 five-, seven-, and nine-year-olds. Children's field-dependence was measured with the Children's Embedded Figures Test (CEFT). Children's interpersonal problem solving ability was measured with the Preschool Interpersonal Problem Solving Test (PIPS Test). Statistical methods adopted for data analysis were frequencies, percentiles, means, standard deviation, t-test, oneway ANOVA. $Scheff{\acute{e}}$ test and Pearson's correlations. Major findings were that (1) The older children were more field-independent than the younger ones (2) The older children suggested more problem solving methods and higher-level problem solving strategies than the younger ones. (3) Children suggested higher-level problem solving strategies in contexts involving familiar as opposed to unfamiliar participants and contexts involving children as opposed to adults. (4) 9-year-olds' field-independence was positively associated with interpersonal problem solving ability.

In this paper, the wave propagation in an infinite poroelastic cylindrical bone with cavity is studied. An exact closed form solution is presented by employing an analytical procedure. The frequency equation for poroelastic bone is obtained when the boundaries are stress free and is examined numerically. The magnitude of the frequency equation, wave velocity and attenuation coefficient are calculated for poroelastic bone for different values of magnetic field, density and frequency. In wet bone little frequency dispersion was observed, in contrast to the results of earlier studies. Such a model would in particular be useful in large-scale parametric studies of bone mechanical response. Comparison was made with the results obtained in the presence and absence of magnetic field. The results indicate that the effect of magnetic field, density and frequency on wave propagation in poroelastic bone are very pronounced.

DWI of biological effects are independent of magnetic field strength in various regions. High field strength, however, does affect the signal to noise ratio (SNR) and artifacts of diffusion weighted imaging (DWI) images, which ultimately will influence the quantitative of diffusion imaging. In this study, the effects of field strength on DWI are reviewed. The effects of the diseases also are discussed. Comparing DWI in cerebellum, WM, GM, Hyperacute region measurements both as a function of field strength (1.5T and 3.0T). Overall, the SNR of the DWI roughly doubled going from 1.5 T to 3.0 T. In summary, DWI studies at 3.0 T is provided significantly improved DWI measurements relative to studies at 1.5T.

This study began to classify the studies on 'culture' in the field of environmental design overall. The classifying process adopted not the approach to preselect the criteria but the phenomenological inductive approach and content analysis method focusing on environmental design in order to understand which place the environmental design had taken. As a result, following aspects were reviewed: what is the area in which the studies on culture is made under the environmental design; what is the trend of using the word 'culture' in terms of logical connection; what is the level of approach to culture from the viewpoint of search, correspondence or application stage. On the whole, followings were drawn as conclusions. First, the interest of the studies on culture has been increased with time especially in the field of interior design. Second, the word 'culture' has become to be used a lot as 'cultural', and was used together with traditional, enterprise and material. Lastly, culture was studied at a starting point by and large. Although the papers, the objects of this study, are confined to five kinds of journals, the analysis of them is helpful to preestimate the trend of studies on culture because they have propensity to lead the international professional academic world.

Objectives : The purpose is to discuss the clinical applications of Orungsan(Goreisan: 五苓散) as an alternative management for increased intracranial pressure in the field of neurosurgery in Japan. Methods and Results : Attention has focused on Kampo medicine(traditional Japanese medicine) for some cerebral disease including chronic subdural hematoma(CSDH) and cerebral infarction in Japan. Orungsan and one of its classes, Sirungtang(Saireto: 柴苓湯) are well known their effects on brain edema. After some studies of Orungsan has the anti-edemic effects by the inhibition of aquaporin, this herbal medicine has been used widely in the neurosurgery field in Japan. It is high time to think about where we are and we go ahead for the progress and the integration in medicine. We have reviewed the studies using Orungsan or Sirungtang, that was reported at the 20th annual meeting of 'the Japan society for Kampo medicine and neurological surgery' was held on November 5, 2011 in Tokyo. Fifteen studies related with Orungsan or Sirungtang were reported among all 32 studies at the meeting. Orungsan in ten, and Sirungtang in five among 14 studies contained specific clinical case. In the aspects of disease, thirteen papers were related with SDH, including CSDH(11), SSDH(1), aneurism clipping for SDH prevention(1), and one was acute cerebral infarction and one was multiple metastatic brain tumor. In the report style, case control study was 7(mostly retrospective), and the case report was 8. Conclusions : Orungsan may be plausible to be an alternative method to reduce brain edema after SDH and other brain injury in the field of neurosurgery.

With a view to contributing to the epistemological and methodological debates in Southeast Asian Studies, the aim of this paper is to examine critically the epistemic concepts and approaches in the social sciences and then to seek an epistemic reflexivity and its potential methodological applications to Southeast Asian Studies. Although the field of social sciences has attempted to search for a means of tackling the ontological and epistemological dilemmas in its major paradigms, Southeast Asian Studies still demands a more 'actor-centered' epistemic account of reflexive interaction between actors and social structures. Bearing in mind the need for a more 'actor-centered' epistemic approach, this paper continues to discuss the 'epistemic reflexivity' in the social sciences and its potential applications to Southeast Asian Studies. In this paper, I will consider 'epistemic reflexivity' as an alternative methodological orientation. It emerges as interlinked with the ontological standpoint of what is called 'reflexive approaches' and its application to the detailed 'reflexive methodology' which I am proposing in this paper. In doing so, this paper discusses the autobiographical experiences of the author arising from his ethnographic field research in North Sulawesi, Indonesia and their implication for a reflexive methodology in Southeast Asian Studies. In conclusion, the paper argues that we need a 'more actor-centered' epistemic framework to compensate for the epistemological and methodological dilemmas in the social sciences and the alternative framework will equip Southeast Asian Studies with a reflexive methodology relevant to the life-dynamics of the social world in the process of developing its inquiries, methodological technics, analysis, and validation.
