Recognizing a Chip on Edge of a Cutting Tool by Hough Transform
Junki Fujii,Masami Konishi 제어로봇시스템학회 2009 제어로봇시스템학회 국제학술대회 논문집 Vol.2009 No.8
Conventionally,?fnished cutting tools are checked by human eyes. Most of the defects are minute and it is needed to be checked with a microscope. Therefore, it is a very labourous work. To light enhuman load, the automatic testing system is required. The aim of this research is the development of are recognizing system for a chip on the edge by using image processing. As the preprocessing methods, a color image of the edge is analized through gray scal-ing, binarization, extraction of the outline by Prewitt-flter and Hough transformation. These procedure sared eveloped and realized in the developed testing system to make the edge detection. To a scertain the effect, estimation of the amount of a chip on the egde is made not only the judgement if it has a chip or not. And using Neural Network, an abnormal chip,abroken edge and a surface defect are recognized.

As a general background, Sabaka-daikon, one of the heirloom vegetables in Kyoto, ceased its commercial cultivation in the late 1960s at north Kyoto, leading to an extinction crisis. We review the activities of the local residents to revive the commercial cultivation of Sabaka-daikon from 2010. We also discuss the significance of the information on the health benefits of local foods in motivating local residents to protect local foods from extinction. For methodology, through field interviews of administrative members, venders, and farmers in Maizuru city, we explore reasons for the success in reviving a local heirloom vegetable, Sabaka-daikon. We also apply chemical analysis to determine individual differences in the anticarcinogenic (cancer preventive) compound, 4-methylthio-3-butenyl isothiocyanate, in Sabaka-daikon to guarantee its added health benefits. As a result, the primary factors for the revival of Sabaka-daikon in Maizuru city include the passion of farmers, measures undertaken by the local administration, and the marketing strategies of venders. The secondary factor is the fact that one primary factor (passion of farmers) coincides on a time axis with the other two factors (administrative measures and marketing strategies of venders). Wide individual differences in the anticarcinogenic compound, 4-methylthio-3-butenyl isothiocyanate, were observed, likely due to the variable genome of Sabaka-daikon. In conclusion, the results imply that the information on the health benefits of daikon contribute to motivating the local residents (i.e., passion of farmers) in protecting Sabaka-daikon from extinction. Revival of this heirloom vegetable would contribute to the diversification of local foods, and to the preservation of those foods and the cooking knowledge for future generations. As Sabaka-daikon variety has some races in variation of 4-methylthio-3-butenyl isothiocyanate production, a race with a fixed amount of 4-methylthio-3-butenyl isothiocyanate should be established to guarantee added health benefits of Sabaka-daikon.

Objective: Some antidepressants have been implicated as risk factors for QT prolongation, which is a predictor of sudden cardiac death. However, the QT interval is considered an imperfect biomarker for proarrhythmic risk. Therefore, we reevaluated the risk of sudden cardiac death due to antidepressants using improved methods, namely, QT dispersion (QTD), T wave peak-to-end interval (Tp-e), and Tp-e/QT ratio. Methods: We compared the effects of antidepressants on QTc (QT/RR1/3), QTD, Tp-e, and Tp-e/QT ratio in 378 patients with mood disorder. We also compared each index between 165 healthy controls and 215 randomly selected age-matched patients. Results: Age (p<0.01), sex (p<0.05), tricyclic antidepressant (TCA) use (p<0.05), and clomipramine (p<0.01) and mianserin (p<0.05) use in particular, significantly associated with a prolonged QTc. We also found that age (p<0.01), TCA use (p<0.05), and clomipramine (p<0.01) and mianserin (p<0.05) use in particular, significantly prolonged QTD. However, there was no correlation between each variable and Tp-e or Tp-e/QT ratio. Significant differences in QTc and QTD were found between the patients and healthy controls. Conclusion: From our results, prediction of risk of sudden cardiac death by QTD, Tp-e, or Tp-e/QT ratio was inconsistent. Increased QTD may be more suitable for predicting sudden cardiac death due to antidepressants.

Obesity is an established risk factor for colorectal cancer. Pioglitazone is a peroxisome proliferator activated receptor$receptor{\gamma}$ ($PPAR{\gamma}$) agonist that induces differentiation in adipocytes and induces growth arrest and/or apoptosis in vitro in several cancer cell lines. In the present study, we investigated the effect of pioglitazone on the development of azoxymethane-induced colon aberrant crypt foci (ACF) in KK-$A^{\mathcal{Y}}$ obesity and diabetes model mice, and tried to clarify mechanisms by which the $PPAR{\gamma}$ ligand inhibits ACF development. Administration of 800 ppm pioglitazone reduced the number of colon ACF/mouse to 30% of those in untreated mice and improved hypertrophic changes of adipocytes in KK-$A^{\mathcal{Y}}$ mice with significant reduction of serum triglyceride and insulin levels. Moreover, mRNA levels of adipocytokines, such as leptin, monocyte chemoattractant protein-1 and plasminogen activator inhibitor-1, in the visceral fat were decreased. PCNA immunohistochemistry revealed that pioglitazone treatment suppressed cell proliferation in the colorectal epithelium with elevation of p27 and p53 gene expression. These results suggest that pioglitazone prevented obesity-associated colon carcinogenesis through improvement of dysregulated adipocytokine levels and high serum levels of triglyceride and insulin, and increase of p27 and p53 mRNA levels in the colorectal mucosa. These data indicate that pioglitazone warrants attention as a potential chemopreventive agent against obesity-associated colorectal cancer.
