Hydrothermal process has been applied for effective production of Hydrogen from biowastes. In this study hydrothermal process for production of valuable Hydroxylapatitefrom chicken manure containing phosphorus was focused on. Conditions of 400?C and 26 - 27 MPa with addition of 1 mmol Ca(OH)2 were determined as the optimal by using O-phospho-DL-serine as a model compound. Afterwards, the real biowaste containing phosphorous, chicken manure was processed under the same conditions. Formation of a Hydroxylapatite;in the solid residue was confirmed from X-ray diffraction (XRD) patterns, after purification. It was found that 27.9% of P in the chicken manure was converted to Hydroxylapatite. With the use of acetic acid as a chemical purification medium, Hydroxylapatite was obtained.

＜正＞A novel method of the deoxidation of the molten iron has been proposed with in-situ production of the magnesium vapor by aluminothermic reduction of magnesia. A reaction model has been developed to examine the rate controlling mechanism and highly efficient deoxidation with the magnesium vapor. The model calculation results show that, in order to achieve the high efficiency, control of the magnesium vapor pressure in the injected bubble is essential.

Objective: This study aimed to evaluate the immediate psychological effects of coordination exercises on women in Japan. Methods: The subjects were 17 adult women (height, 160.1 ± 5.1 cm;weight, 54.3 ± 10.5 kg;age, 57.8 ± 8.3 years) living in the community and attending a fitness club. The subjects performed a coordination exercise called Life Kinetik®. The subjects responded to the Two-Dimensional Mood Scale–Short Term before and after performing 30 minutes of Life Kinetik®. The results were tabulated and four psychological states were calculated (i.e., vitality, stability, pleasure, and arousal). The pre- and post-implementation results were statistically analyzed using a corresponding t-test. Results: Significant differences were found in activation and arousal levels, but not in stability and comfort levels. Conclusion: The coordination exercise, Life Kinetik®, was found to be an exercise program with potential psychological benefits, as it could change women’s psychological condition to active and excited states.

In Western countries, clinical trials on prostate cancer screening demonstrated a limited benefit for patient survival. In the Asia-Pacific region, including Japan, the rate of prostate-specific antigen （PSA） testing remains very low compared with Western countries, and the benefits of population-based screening remain unclear. This review describes the current status of population screening and diagnosis for prostate cancer in Japan and discusses the efficacy of population screening for the Asian population. Since the 1990s, screening systems have been administered by each municipal government in Japan, and decreases in the prostate cancer mortality rate are expected in some regions where the exposure rate to PSA screening has increased markedly. A population-based screening cohort revealed that the proportion of metastatic disease in cancer detected by screening gradually decreased according to the increased exposure rate, and a decreasing trend in the proportion of cancer with high serum PSA levels after population screening was started. The prognosis of the prostate cancer detected by population screening was demonstrated to be more favorable than those diagnosed outside of the population screening. Recent results in screening cohorts demonstrated the efficacy of PSA. These recent evidences regarding population-based screening in Japan may contribute to establishing the optimal prostate cancer screeninK system in Asian individuals.
