Photoluminescence (PL) imaging is curried out using Cr doped spinel sensors at various temperatures for 2-dimensional fluorescence thermometer application. PL images can be clearly observed using a CCD camera and UV, green and/or blue LED illuminations. Brightness of PL images from Cr doped spinel sensor decrease with temperature up to 250 oC. PL imaging is suggested to be useful for 2-dimensional fluorescence thermometer applications.

Spinel crystals (Cr doped MgAl2O4) with various Cr2O3 and MgO concentrations are grown using floating zone technique for fluorescence thermometer application. Temperature dependence of photoluminescence (PL) intensity is evaluated using spinel crystal and/or composite of spinel with silicone resin. PL intensity from spinel crystal and composite decreases linearly with temperature. Spenel crystal and composite are useful as sensor materials in fluorescence thermometer.

Temperature monitoring is essentially important for stable control of fabrication processes. In order to develop a convenient 2-dimensional temperature monitoring system using a thermo-paint, photoluminescence (PL) images are observed from the luminous paints at various temperatures. Commercially available and in-house modified luminous paints are evaluated for improving temperature sensitivity and stability of the thermo-paints. Temperature dependences of PL images from various luminous paints are reported for developing temperature monitoring procedure using a thermo-paint.

Study Design: Cross-sectional study.Purpose: This cross-sectional study aimed to investigate the risk factors for osteoporosis in men by assessing bone mineral density (BMD), skeletal muscle mass, body fat mass, grip strength, and advanced glycation end products (AGEs).Overview of Literature: Fewer studies have reported the correlation between BMD and skeletal muscle mass in women. Moreover, a few studies have examined the relationship between osteoporosis and skeletal muscle mass.Methods: This study included 99 men (mean age, 74.9 years; range, 28–93 years) who visited Qiball Clinic for BMD and body composition examinations. The osteoporosis group consisted of 24 patients (mean age, 72.5 years; range, 44–92 years), and the control group consisted of 75 individuals (mean age, 74.9 years; range, 28–93 years). Whole-body skeletal muscle mass was measured using a bioelectrical impedance analyzer. BMD was measured by dual X-ray absorptiometry. Skin autofluorescence (SAF), a marker of dermal AGE accumulation, was measured using a spectroscope. Osteoporosis was defined as a bone density T score of –2.5 or less. Physical findings, skeletal muscle mass, BMD, grip strength, and SAF were compared between the osteoporosis and control groups.Results: The osteoporosis group had significantly lower trunk muscle mass (23.1 kg vs. 24.9 kg), lower leg muscle mass (14.4 kg vs. 13.0 kg), and skeletal mass index (7.1 kg/m<sup>2</sup> vs. 6.7 kg/m<sup>2</sup>) than the control group (all <i>p</i><0.05). Lower limb muscle mass was identified as a risk factor for osteoporosis in men (odds ratio, 0.64; <i>p</i>=0.03).Conclusions: Conservative treatment of osteoporosis in men will require an effective approach that facilitates the maintenance or strengthening of skeletal muscle mass, including exercise therapy with a focus on lower extremities and nutritional supplementation.
