Currently, there have been issues concerning the depletion and scarcity of mineral resources. This is mostly due to the excavation of high grade minerals having already occurred years and years ago, hence forcing the mining industry to opt for the production and optimization of lower grade minerals. This however brings about a plethora of problems, many of which economic, stemming from the purification of those low grade minerals in various stages required for mineral processing. In order to reduce costs and aid in the optimization of the mining stream, this study, introduces an automatic mineral identification system which combines the predictive abilities of deep learning with the excellent resolution of hyperspectral imaging, for pre-stage of mineral processing. These technologies were used to identify and classify high grade arsenic (As) bearing minerals from their low grade mineral counterparts non-destructively. Most of this ability to perform such tasks comes from the highly versatile machine learning model which employs deep learning as a means to classify minerals for mineral processing. Experimental results supported this statement as the model was able to achieve an over 90% accuracy in the prediction of As-bearing minerals, hence, one could conclude that this system has the potential to be employed in the mining industry as it achieves modern day system requirements such as high accuracy, speed, economic, userfriendly and automatic mineral identification.

Damping-off of kale (Brassica oleracea L., Acephala group) was found in Iwata, Shizuoka, Japan in 2016. Isolates obtained from basal stems with typical symptoms were identified as Rhizoctonia solani AG-4 HG-I. Original symptoms were reproduced on healthy kale seedlings after inoculation with the isolates, and inoculated fungi were reisolated from the diseased plants. This is the first report of kale damping-off caused by R. solani in Japan; therefore, we refer to this new disease as “damping-off of kale”.

Erectile dysfunction following radical prostatectomy (RP) is still a significant burden as a post-operative morbidity, despite advances in nerve-sparing techniques and penile (erectile function) rehabilitation (PR) programs. We assessed the effects of stimulation with the masturbation device "EGG" on enhancement of erectile response along with administration of phospho diesterase type 5 inhibitor. We also studied the change of self-esteem and motivation for continuation of PR after stimulation with EGG. Eight nonresponders for PDE5-I who underwent retropubic RP were enrolled. Patients' median age was 71.5 years old. No patients received adjuvant therapy for prostate cancer. The patients' erectile response in the penile rehabilitation session (masturbation) with PDE5-I+manual stimulation and PDE5-I+stimulation with EGG were evaluated by erection hardness score (EHS). Changes of self-esteem and motivation for penile rehabilitation were assessed by the self-esteem subscale of the Self-Esteem and Relationship (SEAR) questionnaire and one original question, respectively. PDE5-I + stimulation with EGG significantly enhanced EHS compared to PDE5-I+manual stimulation in the eight patients (p=0.027). Transformed score of self-esteem subscale score of SEAR questionnaire was significantly increased in the PR session with EGG compared to the PR session with manual stimulation (p=0.043). Six patients who showed a better erectile response with EGG retained motivation for continuation of PR. PDE5-I+stimulation with EGG improved the erectile response in post-RP patients. EGG as a masturbation device may have a potential for contribution to successful PR.

現在のONUは屋内設置を前提に設計されている。しかし、光ファイバを加入者宅内まで敷設した場合、光線路の切分けが困難になり、保守上支障を来すことが考えられることから、ONUが屋外設置の可能性も考察する必要がある。この場合、コネクタ損失分を含む線路損失の低減が可能となるが、従来の設計温度範囲に比較して広範囲な環境温度の変化が予想される。そこで、温度に対する伝送特性劣化について検討が必要となるため報告する。
