真空調理法によるイカ肉の物性および食味特性を通常調理法と比較し, 真空調理については加熱温度や加熱時間の影響を物性, クッキングロスおよびスペースロス, 肉中のプロトン緩和曲線から検討し, 官能評価との関連性をみた.結果は次の通りである.(1) 真空調理時の加熱温度は40, 50, 60, 70および80℃について検討したところ, 温度の上昇に伴うイカ肉の硬さは40, 50, 60℃と上昇するに従い軟らかくなり, 60℃で最も軟らかい値を示した.さらに60℃を越すと加熱温度の上昇とともに硬くなることが認められた.クッキングロスは温度の上昇に伴い大となった.(2) イカ肉の真空調理の加熱時間の影響を20分間から50分間加熱について比較したところ, その差は認められなかった.(3) イカ肉中の水の動きの変化は60℃付近から起こり, 水分含量の減少や緩和時間丁2値の上昇は70℃加熱の肉に認められた.(4) 官能評価においては外観や食感に関する食味特性および嗜好について検討したが, 60℃および80℃加熱はともに好まれない傾向を示し, 70℃-30分間加熱により嗜好性の向上が認められた.(5) 以上の結果から, イカ肉の真空調理に適した加熱温度は約70℃であり, 加熱時間は20~30分間が適当と考えられた.(6) 真空調理法によりイカ飯を調製したところ, 煮込み調理に比べて官能評価の食感の項目でより好まれる傾向を示した.また調理操作の面では加熱中の攪拌が不必要であり, 少量の煮汁で加熱が可能であるなどの利点が認められた.

To establish the superiority of monocular presentation in augmented reality (AR) over binocular presentation, we report two experiments involving a tracing task with an AR image covering a visual field observed in both the monocular and binocular conditions. In Experiment 1, the subjective visibility of the AR image and the accuracy of the tracing task were measured. In Experiment 2, participants identified a character in the AR image while tracing. The AR image was less visible in the monocular condition than in the binocular condition. Hence, participants could observe the real world more easily in the monocular condition, and the resulting performance on the tracing task was better in the monocular condition. Information acquisition from the AR image in the monocular condition was equivalent to that in the binocular condition. These results exhibit the superiority of monocular AR presentation for the performance of manual tasks.

Development and endocrine changes in Thoroughbreds colts and fillies were compared between those reared at two facilities of the Japan Racing Association, the Hidaka Training and Research Center (Hidaka) and Miyazaki Yearling Training Farm (Miyazaki). Thoroughbred colts and fillies born in Japan between 2003 and 2010 were used. Each colt group and filly group was divided into 2 groups, respectively, and raised in Hidaka or Miyazaki for 7 months from September at 1 year old to April at 2 years old. For the growth parameters, the body weight, height at withers, and girth and cannon circumferences were measured once a month. For parameters of endocrine function, circulating prolactin, luteinizing hormone (LH), follicle-stimulating hormone (FSH), insulin-like growth factor-1 (IGF-1), testosterone, progesterone, and estradiol-17β levels were measured. Regarding growth, the rate of increase over the 7-month period was significantly higher in both colts and fillies raised in Miyazaki than in Hidaka in all 4 parameters: body weight, height at withers, and girth and cannon circumferences. The endocrine changes of the colts and fillies born in 2007 were as follows. In colts, although circulating prolactin tended to be higher in colts reared in Hidaka from October to April, circulating LH, FSH, testosterone, estradiol-17β and IGF-1 tended to be higher in colts reared in Miyazaki than in Hidaka, suggesting that the gonadotropin-releasing hormone-LH/FSH system and the growth hormone-IGF-1 system were more active in colts reared in Miyazaki as compared with those reared in Hidaka. In fillies, circulating prolactin tended to be higher in fillies reared in Hidaka in February and March, but no significant difference was noted in the serum LH, FSH, IGF-1, or progesterone level between the 2 groups. Circulating estradiol-17β tended to be higher in fillies reared in Miyazaki than in Hidaka in October and November. Regarding ovarian function, the initial ovulation occurred by the end of March in 2 (16.7%) of 12 fillies reared in Hidaka and 7 (38.9%) of 18 fillies reared in Miyazaki, suggesting that the ovarian function was more active in fillies reared in Miyazaki as compared with those reared in Hidaka. Based on these findings, it was clarified that development of the body and gonads was faster in Miyazaki compared with Hidaka in both colts and fillies.
