This paper examines the issue of deepfake technology from technological and ethical perspectives. This technology has the potential to revise the traditional notion of replication and undermine the evidentiary capabilities of video and audio. The development of deepfakes also risks creating a threat to authentication technology. Pornographic videos using deepfake technology have also become a social problem. Therefore, this paper examines what possible countermeasures can be taken to address the risks of this new technology. Moreover, we argue that engineers who develop AI programs should consider the risks seriously.

Recently, because aging is progressing in our country, cerebral disease is becoming a serious problem. Therefore, viewing this problem objectively, we can say support of aging and dementia patients is a very useful research theme. In this time, we examine the drinking condition as one noticing point in a case of carrying out the rank evaluation of dementia. Because it is generally known the condition like dementia by alcohol, dementia is deeply involved with alcohol. In this time's experiment, we examined the condition like dementia by alcohol. We carried out the experiment to observe an internal condition (cognitive ability) and an external condition (expression control ability) for the first stage and second stage in drinking level. First, by assessment of cognitive ability, though decline of cognitive ability by drinking occurs whole brain, it is shown to influence to left-brain in first step. Next, by assessment of expression control ability, we showed AU influenced by drinking in expression's output level. By these 2 experiments, we found out the concrete symptom of the condition like dementia by alcohol. In future, we examine the relationship between the condition like dementia by alcohol and dementia, and then we proceed advancing of rank evaluation of dementia.

本研究は認知症の予防に対する作り笑いの可能性を探ることを目的としている.本稿では,作り笑いがストループ効果と顔表面温度に与える影響について述べる.はじめに実験で用いた作り笑いじゃんけんシステム,笑み筋体操およびストループ効果について述べる.実験ではストループ効果を指標として用いて,作り笑いじゃんけん評価実験を行い,認知症の予防に対する作り笑いの可能性を示した.次に笑み筋体操顔表面温度変化実験を行い,笑み筋体操によって顔の表面温度を上昇させることを示した.
