Background and Objectives: The aim of the study was to identify the factors associated with life satisfaction of hospitalized Vietnam veterans. Material and Methods: The data were collected from 200 hospitalized Vietnam veterans of 5 veterans hospitals in Korea from September 13 to 23, 2004. Information of general characteristics, health behavior, disease history, family function, depression and life satisfaction were collected by structured questionnaire. Results: The mean of life satisfaction was 21.48(±6.03), and the mean of depression was 53.10(±9.64). The prevalence of depression was mild depression 24.0%, moderate depression 43.5% and severe depression 25.0%. Depression was associated with life satisfaction and depression was higher, life satisfaction was lower. Family function and age were positively associated with life satisfaction, Conclusion: Life satisfaction was affected by depression and family function in hospitalized Vietnam veterans. Therefore, it was thought that psychosocial approaches such as improve depression and family function in care of hospitalized Vietnam veterans is required.

This research is done to design and manufacture prototype clean room garments to improve the product yield of the clean room processing. To assist the research, other papers and references on the same subject were collected for analysis. Also the researcher made interviews with the workers at the clean room. The prototype garments made for this project was compared against the commercially available clean room garments used in the industry. A set of test was conducted to measure particle release from the garments. The prototype clean room garments was manufactured after having considered all the aspects stated above, and tested for the level of particle release. The test subjects performed 4 different movements(marching, arms stretch, squat and rise, and jogging) while wearing the prototype garments and commercially available clean room garments. Particle counts produced by each movement were measured. The data collected was statistically analyzed. The followings are the result of the test. 1) Overall, the prototype garments yielded less particle release.(p<0.001) 2) It showed greatest difference of particle counts for jogging(p<0.001) and squat and rise(p<0.001). In the arms stretch test, the prototype garments was also more effective in controling the particle, however, in the marching test, no significant difference was detected. 3) The prototype garments had less particle release in upper(p<0.001), middle(p<0.001), and lower level(p<0.01) than the commercially available clean room garments. Manufacturing a new fabric for the clean room processing is important, but this research proves that the design of the clean room garments also determines the efficiency garments in the particle control. Therefore the same fabric can perform differently according to how it is designed. Improving the design will also improve the particle control and reduce the cost of research. Eventually, the manufacturers will increase the product yield.

Proper regulation of bone morphogenetic protein (BMP) signaling is critical for correct patterning and morphogenesis of various tissues and organs. A well known feedback mechanism is a BMP-mediated induction of Smad6, an inhibitor of BMP signaling. Hoxc8, one of the Hox family transcription factors, has also been shown to negatively regulate BMP-mediated gene expression. Here we add another level of Hoxc8 regulation on BMP signaling. Our results show that Hoxc8, when over-expressed in C3H10T1/2 or C2C12 cells, suppressed basal Smad6 promoter activity and its mRNA expression. Activation of Smad6 transcription either by BMP2 treatment or Smad1 over-expression was also abolished by Hoxc8. When chromatin was precipitated from mouse embryos with anti-Smad1 or anti-Hoxc8 antibody, Smad6 promoter sequence was enriched, suggesting that Hoxc8 proteins make complexes with Smad1 in the Smad6 promoter region. Yet, a lack of Hox binding motifs in the Smad6 promoter sequence suggests that instead of directly binding to the DNA, Hoxc8 may regulate Smad6 expression via an indirect mechanism. Our results suggest that the Smad6-mediated negative feedback mechanism on BMP signaling may be balanced by the repression of Smad6 expression by Hoxc8.

Intraneuronal deposition containing $\alpha$-synuclein is implicated in the pathogenesis of synuclein-opathies including Parkinsons disease (PD). Although it has been demonstrated that cytoplas-mic inclusions of wild type $\alpha$-synuclein are observed in the brain of PD patients and that $\alpha$-synuclein mutations such as A30P and A53T accelerate aggregate formation, the exact mech-anism by which $\alpha$-synuclein forms insoluble aggregates is still controversial. In the present study, to understand the possible involvement of tissue transglutaminase (tTG) in aggregate formation of $\alpha$-synuclein, SH-SY5Y cell lines stably expressing wild type or mutant (A30P or A53T) $\alpha$-synuclein were created and aggregate formation of $\alpha$-synuclein was observed upon activation of tTG. The data demonstrated that $\alpha$-synuclein negligibly interacted with tTG and that activation of tTG did not result in the aggregate formation of $\alpha$-synuclein in SH-SY5Y cells overexpressing either wild type or mutant $\alpha$-synuclein. In addition, $\alpha$-synuclein was not modi-fied by activated tTG in situ. These data suggest that tTG is unlikely to be a contributing factor to the formation of aggregates of $\alpha$-synuclein in a stable cell model.
