Amish 집단(미국 오하이오주 홈스카운터 거주)의 vitamin E 영양상태를 24시간 회상법, 영양보충제의 사용량 조사 colorimetric법에 의한 혈장 vitamin E의 분석으로 평가하였다 평균식이 섭취 vitamin E는 7.4mg a-tocopherol equivalent였으며 평균 181.4 IU는 영양보충제로 섭취했다 전체 vitamin E의 67.7% 는 식이를 통해 섭취했으며 32.4%는 영양보충제를 복용함으로 섭취했다 평균 혈장 vitamin E 농도는 13.4mg/ml였다 혈장 vitamin E와 영양제로 복용한 vitamin E 사이에는 유의적인 상관과계가(r=0.489 p=0.0001)를 보여주었고 혈장 vitamin E와 연령과도 상관관계(r-0.216, p=0.0017)가 있었다 Amish 집단의 vitamin E 영양상태는 충분했으며 이집단 중의 어떤 자들은 고단위의 다량의 vitamin E 영양제를 복용하고 있어 vitamin E에 대한 올바른 정보를 알려주고 효율적인 영양교육을 시킬 필요성이 요청되었다.

This study investigated the location conditions, spatial linkage structures, and firm specific problems of small firms of the Greater Cincinnati metropolitan area by sectors and by areal distribution. The major locational advantages were closeness to customers and suppliers followed by accessibility to inter-state highways. These results were supported by spatial linkage structures in which within-region linkages occupied a greater portions of linkage, showing the importance of small firms in the regional economy. The linkage patterns showed distance decay effect with high elasticity. While there were no significant differences of locational conditions and spatial linkage structures of small firms between core and peripheral area, a slight difference was identified among sectors. Chemical related manufacturing firms show different locational conditions and spatial linkage structure with weak within-local linkages. The main locational disadvantages were lack of qualified labor, undesirable neighborhood, heavy tax, and space shortage. Considering the biggest problems such as lack of qualified labor, difficulties in sales/marketing, low accessibility to financial resource, and technological inability, the inter-related cooperative business networks among firms and regional institutions, consulting companies, chamber of commerce, and universities are needed to stimulate regional economic development and survival of small firms.

This study examines why families move to neighborhoods at different levels of income. By analyzing a survey dataset of homeowners who sold and bought a house in 1999 in Franklin County, Ohio, in USA on their mobility decisions, this study examined the factors associated with cross-income residential location decisions. I categorized both survey respondents and neighborhoods into low-, middle-, and high-income levels and ran multinomial logit analyses for each of the low-, middle-, and high-income family groups to examine why families moved to neighborhoods at different levels of income. The analysis suggests that middle-income families moved to high-income neighborhoods because of school reputation and moved to low-income neighborhoods because of investment purposes.

The spatial distribution of crime incidences in urban neighborhoods is a reflection of their socio-economic environment and spatial inter-relations. Spatial interactions between offenders and victims lead to spatial autocorrelation of the crime incidences. The spatial autocorrelation among the incidences biases the interpretation of the ecological model in OLS framework. This research investigates residential crimes using residential burglaries and robberies occurred in the city of Columbus, Ohio, for 2000. In particular, the spatial distribution of incidence rates of residential crimes are accounted in OLS framework using eigenvectors, which reflect spatial dependence in crime patterns. Result presents that handling spatial autocorrelation enhanced model estimation, and both economic deprivation and crime opportunity are turned out significant in estimating residential crime rates.

There is growing consensus among planners and policymakers that brownfield remediation has positive impacts on neighborhoods in terms of housing prices, public health, and environmental quality. However, there is a limited understanding of how brownfield redevelopments spatially affect neighborhood housing turnover and stability. This paper addresses the spatial impacts of brownfield redevelopments on neighboring housing turnover in Cuyahoga County, Ohio. This study examines housing turnover before and after the remediation of brownfield sites countywide and in housing submarkets stratified by household income. Based on housing sales data between 1996 and 2007, the extended Cox Hazard model with the difference-in-difference approach is employed to clarify the causal relationships between brownfield redevelopments and neighboring housing turnover. Additionally, along with the results of the previous study examining impacts of brownfield remediation on nearby housing prices, this paper estimates the change of neighborhood stability due to brownfield redevelopments based on both attributes of housing prices and turnovers.

In the United States, a marked emphasis on personal achievement has been among enduring values characterizing American culture from the beginning of the republic. Particularly, Americans have attached great value to the spirit of self-reliance in striving for personal achievement. However, there have been few empirical studies focusing on the effects of Americans' self-reliant spirit on American electoral politics. Through a field experimentation focusing on the voters of Portage County in Ohio, this study examined the effects of Americans' self-reliant spirit on the evaluations of presidential candidates' personal traits, which constitute the candidates' character. The results of this study demonstrated that American voters evaluated those presidential candidates who were described as self-reliant significantly more favorably than the presidential candidates who were not so described, for 8 out of the 11 personal traits. The findings provide meaningful evidence for ascertaining the potential and legitimacy of the influences of the spirit of self-reliance, in the American society including electoral politics.

It is often challenging to evaluate local spatial association among onedimensional vectors generally representing paired-location events where two points are physically or functionally connected. This is largely because of complex process of such geographic phenomena itself and partially representational complexity. This paper addresses an alternative way to identify spatially autocorrelated paired-location events (or vectors) at a local scale. In doing so, we propose a statistical algorithm combining univariate point pattern analysis for evaluating local clustering of origin-points and similarity measure of corresponding vectors. For practical use of the suggested method, we present an empirical application using transactions data in a local housing market, particularly recorded from 2004 to 2006 in Franklin County, Ohio in the United States. As a result, several locally characterized similar transactions are identified among a set of vectors showing various local moves associated with communities defined.

A series of bench scale activated sludge units were operated to find the causes of filamentous bulking(Schizothrix calcicola) at the Southerly Wastewater Treatment Plant. The results shows that the algal bulking problem is caused by the combination of fermented brewery waste and a low/high DO pattern in the aeration basin. The volatile fatty acids in the influent are not themselves the only cause of bulking but indicators of an unidentified substance that either suppresses zoogloeal growth or stimulates algal growth during low DO conditions, because the volatile fatty acids do not stimulate algal growth unless they are added to a sewage that already contains, some fermented brewery waste.
