The purpose of this paper is to propose a method of calculating the sentiment value of a tweet based on the emoticon role.

Classification of emoticon roles as four types showing “emphasis”, “assuagement”, “conversion” and “addition”, with roles determined based on the respective relations to sentiment of sentences and emoticons.

Clustering of users of four types based on emoticon sentiment.

Formalization, using regression analysis, of the relation of sentiment between sentences and emoticons in all roles.

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.

This study aims to highlight the value of economics, social relations and culture in building a healthy community by interpreting qualitative data.

A qualitative descriptive approach was used between June 2016 and May 2017 and interviews were analysed inductively. Twenty residents of a shopping street in Tohoku, a rural town in north-eastern Japan, participated in this survey. This study focused on the residents’ value of economics, social relations and culture in building a healthy community.

People acquired economic benefits in the hope of gaining irreplaceable relationships with customers and residents, including memorable stories and heart-to-heart satisfaction. The narratives reflected not only the ideal aspects of social relations but also realistic and complex aspects, such as feelings of being uncomfortable with strangers, whether they were long-term residents or newcomers. The daily life of the town is a story, which is built based on customs fostered and strengthened through capital bonds.

To build a healthy community, people residing on shopping streets have unique care systems in which multiple glass shop windows make it easier to tell narrative stories, communicate or request assistance, which is very different from knocking on doors in suburban neighbourhoods.

Despite the growing popularity of online secondhand platforms globally, there is a lack of studies exploring how consumers worldwide perceive contamination and the use of secondhand goods differently according to the culture. Based on the consumer contamination theory, this study aims to investigate the cultural differences of South Koreans and Americans by examining three variables (e.g. transaction type, ownership duration and physical attractiveness) related to consumers' perception of contamination and purchase intentions for a secondhand apparel item.

Data were collected from 422 US and South Korean female consumers who were assigned to an experimental scenario, and their secondhand purchase intentions and perceived contamination were compared through independent t-tests and moderated regression analyses.

Consumers' purchase intentions increased, and perceived contamination decreased when the transaction type was business-to-consumer (vs consumer-to-consumer), when the item had been owned for a shorter period of time and when the item was sold by an attractive seller. Such effect was more pronounced for South Korean consumers than the US consumers in the negative contamination contexts (i.e. transaction type, ownership duration), but not in the positive contamination context (i.e. attractiveness).

The findings of the study add to the literature on consumer contamination theory through an examination of several negative and positive contamination factors in retail contexts and highlight the role of culture as a critical moderator.

This study aims to re-examine the money stock determination process for South Korea under the assumption of the existence of potential asymmetric (non-linear) relations (a mechanism) between the money stock and the monetary base. Because, the true and detailed diagnosis of this mechanism is crucially important for the Bank of Korea’s (BOK)’ monetary policy, as this country has been adopting an inflation targeting policy (ITP) for a long-time.

This paper applies the non-linear autoregressive distributed lag model by Shin et al. (2014). This model separates the original series of the monetary base into their increases (+) and decreases (−). The increases (+) and decreases (−) done by the BOK correspond to expansionary and contractionary monetary policies, respectively, in this study.

The empirical findings are two-fold. First, the money stock determination process in Korea has a non-linear (asymmetric) structure. This means that increases (+) and decreases (−) in the monetary base have asymmetric (different) impacts on money stock. Second, the BOK’s only expansionary monetary policy exhibits exogenous nature money stock determination with an almost stable money multiplier. These findings may help the BOK to take preventive precautions in its monetary policy implementations.

This study with its methodology may help the BOK to take preventive measures in its ongoing ITP proactively.

Recently, considerable attention has been attracted to the development of the new concept motor for EV or HEV. Wider torque and speed controllable operating range and high efficiency under driving area are needed for traction motor. The purpose of this paper is to realize the new concept variable field flux motor with claw pole rotor and brushless robust structure for high-speed range.

In the previous paper, the authors proposed a half-wave rectified brushless variable field flux method with a diode inserted into the field winding. This paper presents a designing for a novel claw pole rotor type motor using the variable field flux method (CP-HVFM). The claw pole type rotor has simple and robust structure for high-speed operation. This paper describes a first prototype design result for CP-HVFM using 3D-FEM. And the authors report the torque and efficiency characteristic results using 3D-FEM.

The authors have studied the designing for CP-HVFM using 3D-FEM. The designed prototype CP-HVFM reached a rated power of 2 kW or more at a rated speed 1,800 rpm under design restrictions of experimental equipment and initial specifications. In addition, the authors found the ratio of the tip and root embrace of the claw pole shape for maximum average torque and minimum torque ripple. Finally, the authors revealed an influence of the armature current on the torque and the efficiency characteristic results for the designed prototype CP-HVFM using 3D-FEM.

The half-wave rectified brushless variable field flux method proved to be effective for the claw pole rotor type motor. And also the authors found the best claw pole shape for torque characteristic. This results are applied to another concept motor for EV or HEV.
