The purpose of this study is to determine the parent-perceived effect of adaptive seating devices on the lives of infant or young children with physical and brain lesion disabilities(age 1-13y) and their families. Using the seating device for disabled parents of 42 people with disabilities who use FIATS-AS to investigate functional outcomes. All parents completed the FIATS-AS 4 times-2 times before and 2 times after their child received a new adaptive seating system. Repeated-measures analysis of variance detected significant mean differences among the FIATS-AS scores. Also to estimating the impact of the new seating intervention for the 3 age cohorts using the FIATS-AS scores. The FIATS-AS detected a significant interaction between age cohort and interview time. Providing adaptive seating devices has been found that the positive effects on guardians. The change was significant in 1~7 years of age. Environmental modification, such as seating and other assistive technology devices, may have an important role to play in the lives of young children with disabilities and their families.

Many microorganisms capable of hydrogen photoproduction were isolated from samples of mud fiats of paddy field collected in Seongnam area near Seoul. Among the 63 isolants, a strain K-13 was selected for the capability of hydrogen evolution. As the results of examinations in physiological, morphological and cultural characteristics, the strain K-13 was identified as Rhodopseudomonas gelatinosa.

The rodent uterotrophic assay is currently recommended as one of the primary in vivo assays far endocrine disrupting chemicals by the Organization for Economic Cooperation and Development (OECD) and Endocrine Disruptor Screening and Testing Advisory Committee (US EPA EDSTAC). Generally, this assay relies on the rapid increase in uterus and vagina weights when exposed to estrogenic compounds. Phthalate esters have been used extensively as a plasticizer in the manufacture of plastic products such as PVC films and medical devices. Recently, phthalate esters have been shown to induce endocrine system mediated responses. However, a flew studies have been conducted for the screening of their estrogenic activity. In this study the estrogenic activity of seven phthalate esters, butyl benzyl phthalate (BBP), di(2-ethylhexyl) phthalate (DEHP), di-n-butylphthalate (DBP), diethylphthalate (DEP), di-n-pentylphthalate (DPF), di-n-propylphthalate (DPrP) and dicyclohexylphthalate (DCHP), was examined in uterotrophic assay. Phthalate esters dissolved in corn oil were administered to ovariectomized (OVX) female Sprague-Dawley rats by sub-cutaneous injection for three consecutive days. fiats were sacrificed 24h after final treatment, and then uterus and vagina weights were deter mined. All phthalate esters tested in this assay did not change talc uterus and vagina weights at dosage levels up to 200 mg/kg/day treatment. These results demonstrated that phthalate esters did not exhibit estrogenic activity in vivo uterotrophic assay.
