This paper aims to propose a Web-based system for visualizing local politics in Japan. Although many local governments in Japan provide public access to political documents, researchers and scientists cannot take full advantage of them because they consist only of raw text. Therefore, there is a need for these to be converted into panel data and to visualize differences by region or over time. For ordinary citizens, visualizing differences between the topics discussed by assembly members can be useful in assessing their characteristics. The proposed system aims to provide a complete solution that meets all of these requirements.

The system has five main functions: full-text search for political documents, showing keywords in context, map and time-series visualization, cross-tabulation and political keyword extraction. Although three existing systems offer some of these functions, the proposed system integrates all the five necessary functions and provides a complete solution that meets all of the requirements.

The proposed system is demonstrated to be a complete solution for the requirements based on the comparisons with the existing systems and use cases.

The proposed system, which integrates all the five necessary functions and even adds a new cross-tabulation function, meets all the requirements and is a complete solution for researchers, scientists and ordinary citizens.

In order to be able to use the aroma hand massage as a skill that can be done by a nurse who does not have a special aromatherapy technique, we examine anti-stress effects of simplified aroma hand massage for healthy subjects. We evaluated the anti-stress action of aroma hand massage and the different components of the procedure in 20 healthy women in their twenties. We used autonomic nervous function measured via electrocardiogram as an index of stress. After conducting a baseline electrocardiogram, we induced stress in the participants by asking them to spend 30 minutes completing Kraepelin's arithmetic test. We then administered various treatments and examined the anti-stress effects. Kraepelin's test significantly increased sympathetic nervous function and significantly reduced parasympathetic nervous function. Compared with massage without essential oil or aroma inhalation, aroma hand massage significantly increased parasympathetic nervous function and significantly decreased sympathetic nervous function. The effect of the aroma hand massage persisted when the procedure was simplified. The anti-stress action of the aroma hand massage indicates that it might have beneficial application as a nursing technique. There are several limitations in this study; ambiguities of low component/high component ratio of heart rate variability and bias by small subjects groups of the same women.
