Some oriental medicine turned out to have a significant clinical effect on the cure for dementia. Therefore, thorough scientific tests for physiological effect of oriental medicne are needed. This study is aimed at doing experimental studies on the effects of two medicines, Jowiseungcheongtang and hyungbangjihwangtang, on the cure for dementia.For the demonstration of the effect of the two medicines on aged rats, we perfomed a radial arm medicines on aged rats, water maze task, known for their proper learning paradigm for behavior.Previous studies on aging and dementia show that aged rats displayed significant impariments in the learning of the radial arm maze task compared with younger rats. As in experiment 1, we found that the learning of the radial arm maze task compared with younger rats. As in experiment 1, we found that the learning deficits aged rats exhibit in radial arm maze task were improved with the application of each medicine. The resutls suggest that these two medicine can be effective to patients whose working or shortterm memory is impaired. In experiment 2 we studied the effect of the two medicines on the deficit of the aged rats with the Morris water maze task known for measuring long-tern memory. We did not find significant results between the performance of the ages rats and the younger ones. Considered the different results previous studies have reported, more thorough studies are needed to investigate the effect of the medicines on long-term memory.In conclusion, the results we found in experiment 1 and 2 suggest that Jowisengcheongtang and hyungbangjihwangtang can have useful effects for the cure of age-related memory (especially for short-term memory)deficits. Recent interests in dementia urges researchers concerned to explore the effect of oriental medicine on the disease. As there have been relatively few behavioral or scientific studies on dementia using oriental medicine to date, further studies are expected are expected to continue to elucidate 'what the wisdom of the oriental medicine tells about dementia'.

Although science continues to be a key subject in the education of the majority of young people throughout the world, it is becoming increasingly clear that school science is failing to win the hearts and minds of many of today's younger generation. Researchers have begun to look at ways in which the learning that takes place in museums, science centres and other informal settings can add value to science learning in schools. Four case studies are used to illustrate the potential afforded by informal contexts to research aspects of science learning. The case studies involve: the European Union PENCIL (Permanent European Resource Centre for Informal Learning) project (a network of 14 museums and science centres working with schools to enhance learning in maths and science); a large natural history museum in England; the Tate Modernart gallery in London, and the Outdoor Classroom Action Research Project which involved researchers working in school grounds, field centres and farms. The range of research questions that were asked are examined as are the methodological approaches taken and the methods used to collect and analyse data. Lessons learned from the studies about research in the informal contexts are discussed critically.

Despite the number of developed theories, it still remains a difficult task for some established and emerging scholars in various academic fields to clearly articulate new theories from research studies. This paper reviews and collates the views of scholars on what a theory is and how a good theory can be developed. It explains the concept of a theory, and the different components that make up a theory. The paper discusses the different processes of theory development by emphasizing what theory is and what theory is not. This review found that scholars differ in their definition of a theory, which leads to using terms such as model, paradigm, framework, and theory interchangeably. It found the lack of theoretical constructs in a study to be one of the factors which explains why articles are rejected for publication. This paper may be of benefit to established researchers who may be struggling with theory development, and especially younger academics who are the future of scholarship in various academic fields, particularly in information science.

Researchers have claimed that Korean younger speakers tend to less clearly differentiate aspirated and lax stops with VOT values while older speakers clearly differentiate these two stops with VOT values. To explain this phenomena, the current study consider both an aging effect and a general sound shift. For this study, VOT values and F0 of Korean stops produced by eight male speakers(years of birth were 1942 ~ 1952) analyzed using Praat. Their productions were compared with the values of participants whose year of birth were 1943 ~ 1952) in Silva(2006)'s research. Silva's research was conducted in 2004 using the same methods. The result shows that 2014's VOT gap between aspirated and lax stops and less F0 gap between aspirated and lax stops than those of 2004. When the F0 values related to physical conditions of the larynx is considered, it could be analyzed as the following: to distinguish the three-way phonation type clearly, older speakers depend on the VOT value more instead of F0 which they have difficulty to control.

This paper tried to apply psychosocial factors in industrial safety research. Since Zohar's(1980) publication of safety climate in the field of safety research, this approach have been done by many researchers. Here, this paper reviewed the relationship between safety climate factors(safety rule, prevention, superior attitude, social support) and safety compliance, and the moderating effects of work condition, required skill and age. Based on the responses from 233 employees in Kangwon province industry, hierarchical regressional analysis showed that all safety climate factors(safety rule, prevention, superior attitude, social support) have positive relationship with safety compliance. Safety rule appeared to be more positively related with safety compliance, while work condition is more favorable and worker is older. But social support appeared to be more positively with safety compliance, while work condition is more unfavorable, and also prevention appeared to be more positively with safety compliance, while worker is more younger.

The purpose of this study was to explore musical development of 3- to S-year-old children and their musical home environment. The subjects were one hundred ninety-four children and their mothers enrolled in four kindergartens in Seoul. Each child sang the birthday song with peers in a birthday play setting. It was audiotaped for the children to sing the song. Questionnaire of musical home environment developed by the researchers was used for the mothers. The children's rhythm and pitch development were coded by the scoring categories of Project Spectrum(Krechevsky, 1994). The data were analyzed by t-test, ANOVA, Scheffe, and Pearson correlation. The results of this study were as follows: Firstly, there was no a significant difference in the children's rhythm development among three age-groups as well as between boys and girls. Among rhythm subcategories, the unit of note was ranked in the highest score and the pulse the next. Secondly, there were significant differences in children's pitch development among three age-groups and between boys and girls. The older children significantly achieved higher scores than the younger. Among pitch subcategories, the contour was ranked in the highest score and the interval the next. Thirdly, the children's musical development and their physical home environment related to music were correlated positively. The children's pitch development was significantly related to the mothers' musical attitude and the children's rhythm development to the mothers' educational levels.

The majority of research on institutional theory suggests that the new institutional practices presented by national governments and expert groups is a legitimate demand by society, and that the organization is a passive actor that accepts it. However, individual organizations often perform so-called decoupling acts that run their organizations in their own way instead of following the way the system requires, despite the pressures of a strong institutional environment. In this study, the decoupling behavior of these organizations can be varied by the characteristics of the highest decision maker in the organization based on the upper-echelon theory(UET) even if there is no difference in pressure experienced by individual organizations, and their relationship is empirically analyzed among secondary educational institutions that are relatively strongly regulated by the government. According to the analysis of 192 high schools in Korea, the female principal, the younger the principal, and the higher the educational background, the more likely they are to engage in decoupling behavior that are different from the intent and content of government policies. Therefore, from the results of this study, meaningful theoretical and practical implications can be provided for researchers and managers in the field of knowledge management research.

Previous studies showed that traditional attitudes toward consumer credit and the accumulation of debtare declining, especially among younger life stage groups. The social stigma of high debt levels has largely gone. However, only a few researchers have studied and changes in consumers' attitudes toward credit and its determinants. This study investigates factors related to the probability of respondents having favorable or unfavorable attitudes using the 1992-2004 U.S. Surveys of Consumer Finances. A logistic analysis was used since the dependent variables were binary. All other things equal, respondents in 1995, 1998, 2001 and 2004 were significantly less likely to have favorable or unfavorable attitudes toward credit than otherwise similar respondents in 1992, but the patterns did not correspond well to the changes in the bankruptcy rate. Black and Hispanic respondents were more likely to have favorable attitudes and less likely to have unfavorable attitudes than were otherwise similar white respondents, but those in the Other group, mostly Asians, were not significantly different from whites. Respondents with college degrees were less likely to have a positive attitude and more likely to have a negative attitude than those without a college degree. Respondents who took risks with investments were more likely to have a positive attitude and less likely to have a negative attitude than those unwilling to take risks. Implications for understanding of credit use are discussed. This publication was made possible by a generous grant from the NASD Investor Education Foundation.
