Cu-Zn-S (CZS) films were deposited by the spray pyrolysis method. As-deposited CZS film showed a low crystallinity. The resistivity of CZS film with Cu/(Cu+Zn) ratio of 50% is around 10-2Ω﹒cm. The CZS film elements using spray Cu-Zn (=1:1) solution with thiourea was confirmed as? Cu:Zn:Sn=2:2:3 by ICP-MS and EDX. The band gap of CZS films was varied in the range of 1.8 - 3.5 ev when the? Cu/(Cu+Zn)ratio was increased from 0 to 67%;CZS film with Cu/(Cu+Zn)ratio of 50 % showed an wide band gap of 2 eV. The photovoltaic characteristics were confirmed with cell structure of . The best cell was observed at the CZS films with Cu/(Cu+Zn)ratio of 50%;these cells depicted a conversion efficiency of 1.7%.

AIM:To investigate whether microsomal prostaglandin E synthase-1 (mPGES-1) expression in hepatocellular carcinoma (HCC) and in non-cancerous liver affects HCC prognosis after hepatectomy. METHODS: The relationship between patient clinical prof iles, tumor factors, surgical determinants, and mPGES-1 expression and the recurrence-free survival rate were examined in 64 patients who underwent curative hepatectomy between March 2003 and December 2006. RESULTS: The scores for mPGES-1 expression were higher in well differentiated and moderately differentiated HCC tissues than in poorly differentiated HCC tissues (well differentiated, 5.1 ± 2.7; moderately differentiated, 5.1 ± 1.7; poorly differentiated, 3.0 ± 1.8). In noncancerous liver tissues, the mPGES-1 levels were higher in injured liver tissues than in normal tissues. Cirrhotic livers had higher mPGES-1 levels than livers with chronic hepatitis (normal livers, 3.3 ± 0.7; chronic hepatitic livers, 5.4 ± 1.9; cirrhotic livers, 6.4 ± 1.6). A univariate analysis revealed that the recurrence-free survival rate was signif icantly lower in patients with vascular invasion,a higher mPGES-1 level in non-cancerous liver tissue,a larger tumor diameter (≥5 cm), and a lower serum albumin level (≤3.7 g/dL). The mPGES-1 expression in HCC tissues did not correlate well with postoperative recurrence. A multivariate analysis demonstrated that the presence of vascular invasion and higher mPGES-1 levels were statistically significant independent predictors for early postoperative recurrence of ***: Increased mPGES-1 expression in noncancerous liver tissues is closely associated with the early recurrence of HCC after curative resection.

The Japan Dementia Prevention Society conducted a questionnaire survey of dementia specialists conducted in August 2020. Regarding the worsening of symptoms in people with dementia, 8% answered that they “accept more” and 32% answered that they “recognize a minority”. In the previous research report (Open Journal of Therapy and Rehabilitation Vol.8 No.3), we examined whether hand care therapy (HCT) as one of the passive horticultural therapy was effective in preventing dementia/MCI. Start of the test in August 2018 (I: BL) to February 2020 (VII: 18M) was, the use of HCT was to be effective in preventing dementia and MCI illness and slowing progression. Due to the COVID19 pandemic, VIII (24M) was evaluated in August 2020, and IX (27M) also measured ANS during activity. At that time, they divided into the Group E who had refrained from welfare facilities for the elderly due to the influence of COVID19 and the Group F who HCT continued. In the evaluation of VIII (24M), it was found that the cognitive function of the Group E was significantly reduced compared to VII, and Group F did not show a significant decrease. ADL decreased and depressive symptoms increase by continuing a life with less going out due to the influence of COVID 19 regardless of the use of the facility. It became clear that both Group E and Group F show good changes in ANS balance in the IX. Therefore, by utilizing horticultural therapy that the power of nature and plants in addition to utilizing welfare facilities for the elderly, cognitive impairment in COVID 19. It was expected to lead to prevention and prevention of negative psychology and behavior such
