Japanese language and the influences of computer-mediated communication: how people feel about their language use

This study investigates how Japanese young people feel about their language use, for example, its accuracy and appropriateness. Extensive exposure to Japanese mobile phone email (Keitai-mail) as computer-mediated communication (CMC) may differ in terms of standard language use and grammar. Therefore, this study investigates how CMC affects language use in young people. The results show that Japanese native speakers feel that the advanced part of the Japanese language, such as the polite form (Keigo) and/or kanji (Chinese characters), is difficult. They are also concerned that the dictionary installed on their mobile device will affect their language abilities in both positive and negative ways. Some participants try to read print works in an effort to uphold their literacy standard.

CMC and Its Psychological Motives in Communication: A Case Study in Japanese Mobile Phone-E-Mail

The study investigates 60 young people aged 18 to 30 who are familiar with mobile phone e-mail (Keitai-mail) practices in Japan (a 1-to-1 ratio of male and female, the participants’ domiciles in several big Japanese cities) using a questionnaire on how they feel about CMC communication, in order to elucidate one type of widely used communication methods in the time the IT has been offering the variety of communication platforms. The result shows that senders are ruled by the norms entailed in Keitai-mail communication: Keitai-mail should be responded to immediately but should also be a complete sentence or message. In addition, the expressions used in Keitai-mail vary based on the interlocutors, making Keitai-mail a heavily context-dependent communication medium.

The Language of a Computer-Mediated Communication in Japan: Mobile-Phone E-Mail

This study analyzes a Japanese mobile phone e-mail data corpus (created by the researcher) of 43,295 Keitai-mail exchanged for the purpose of personal communication by 60 young people aged 18 to 30 who are familiar with Keitai-mail practices. The result shows that the Keitai-mail analyzed consists on average of approximately 40 moji (symbols) including 3 emoticons per message, showing that composition is short but not overly abrupt – generally Keitai-mail does not finish in the middle of a sentence. Non-standard textual elements, language plays (LP) such as emoticons, long vowel symbols, irregular use of small moji, and non-standard use of each type of script (e.g., use of Katakana instead of Kanji) are found to be governed by the conventions of Standard Japanese and are not totally random occurrences.

The Pattern of Unique Use of Language: A Case Study in the Greeting Messages ‘Konnichiwa’ and ‘Konbanwa’ on Japanese Mobile Phone E-mail

This study considers the mechanism underlying how people use unique patterns of language use as a greeting message, using Konnichiwa( : good afternoon), and Konbanwa ( : good evening), a simple and common message appearing in Japanese mobile phone e-mail (Keitai-mail), as an example. The data corpus analyzed for this study consists of 43,295 mails for communication purposes from 60 Japanese young people. The result shows that people apply uniqueness in a limited way, and moreover their unique use of language is largely affected by the standard rules of Japanese, including sound information such that as (ha) is pronounced /wa/ (wa).

Social Differences in CMC: a Case Study of Japanese Mobile Phone E-mail

This study investigates how people in different social groups use computer-mediated communication (CMC) in their communication, using Japanese mobile phone e-mail exchanges as an example. The data corpus for this study—43,295 mails for communication purposes from 60 Japanese young people—is analysed, including non-parametric statistical analysis (Mann-Whitney U test and Steel-Dwass test). As for intergroup differences, Keitai-mail are found to be used differently by different age and gender groups. Women create longer texts with more emoticons and non-standard usage of language than men do. At the same time, they also change their style of composition based on the interlocutors’ gender. These differences suggest that code-switching is actively applied in Keitai-mail communication. Other differences found among different gender and age groups relate to what kind of topics they mainly discuss in Keitai-mail: the topics which they generally choose or which are even unconsciously chosen are reflections of their lifestyle. This study illustrates the different uses of a CMC practice based on users’ properties, and further experimental studies (e.g. structural equation modelling) will elucidate more detailed mechanisms of communication practices, or longitude clinical research will evaluate the factors relating to CMC how critical and prolonged they are, with better treatment outcomes.

H-PC: a cloud computing tool for supervising hypertensive patients

Hypertension or high blood pressure is a condition on the rise. Not only does it affect the elderly but it is also increasingly spreading to younger sectors of the population. Treating it involves exhaustive monitoring of patients. Current health services can be improved to perform this task more effectively. A tool adapted to the particular requirements of hypertension can greatly facilitate monitoring and diagnosis. This paper presents the computer application Hypertension Patient Control (H-PC), which allows patients with hypertension to send their readings through mobile phone Short Message Service (SMS) or e-mail to a cloud computing datacenter. Through a graphic interface, clinicians can keep track of their patients, thus facilitating monitoring. Cloud-based datacenters provide a series of advantages in terms of scalability, maintainability, and massive data processing. However, the ability to guarantee Quality of Service (QoS) is crucial for the commercial success of cloud platforms. A novel and efficient cloud-based platform managing H-PC with QoS is also proposed in this paper.

The role of sentence closing as an emotional marker: A case of Japanese mobile phone e-mail

This study investigates how symbols are used as a sentence closing method in Japanese mobile phone e-mail (Keitai-mail), in order to discuss how this practice has extended to increase the possibility of what can be conveyed via written composition.43,295 mails from 60 Japanese young people are analysed in this study. The results show that, as in other CMC practices, emoticons are mostly used as sentence closure devices in the collected data (about 63%), indicating that writers of Keitai-mail naturally use the end of the sentence as a place to add extra-textual messages such as feelings or implications. Moreover, some standard scripts such as periods (‘。’) are also used as emotional markers in addition to their formal usage as simple sentence closing devices. These texting practices can be interpreted as showing that the sentence closing is the most important method since the messages intended to be expressed in Keitai-mail have become more sensitive in terms of reflecting a subtle meaning or implication through this method. The choice of whether to use standard or picture-based symbols contributes to this practice as well.

Efficacy of a programme for workers with metabolic syndrome based on an e-health system in the workplace: a pilot study

We tested the efficacy of the Healthy Workplace programme for metabolic syndrome. A total of 226 workers with metabolic syndrome from 12 companies enrolled in the study and completed baseline and 6-month follow-up. The Healthy Workplace programme consisted of a 4-week structured education module, telephone counselling, mobile phone messages (SMS) and email messages in the ensuing 6 months. The main outcome measures of the pre-post study were waist circumference, high-density lipoprotein (HDL) cholesterol, triglycerides, blood pressure (BP) and glucose levels. At follow-up, waist circumference and diastolic BP were significantly reduced compared to baseline. Triglyceride and fasting glucose levels improved significantly 6 months after the study. At 6-month follow-up, manifest risk factors for metabolic syndrome had disappeared in 9% of the participants. The integrated Healthy Workplace programme encouraged workers to improve self-care behaviours.

Development of Adaptive Kanji Learning System for Mobile Phone

This paper describes an adaptive learning system based on mobile phone email to support the study of Japanese Kanji. In this study, the main emphasis is on using the adaptive learning to resolve one common problem of the mobile-based email or SMS language learning systems. To achieve this goal, the authors main efforts focus on three aspects: sending the contents to a learner following his or her interests, adjusting the difficulty level of the tests to suit the learner’s proficiency level, and adapting the system to his or her learning style. Additionally, this system has already been evaluated by the learners and the results show that most of them benefited from the system and would like to continue using it.

Kei-Tying teens: Using mobile phone e-mail to bond, bridge, and break with social ties—a study of Japanese adolescents

This paper examines the extent to which Japanese adolescents use mobile phone e-mail to bond, bridge, and break with their social ties. Although existing literature shows that adolescents use mobile phone e-mail to bond with intimate strong ties, the fluid nature of social networks during adolescence suggests that mobile phone e-mail may also be used to bridge to new ties and to break with old ties. Drawing on a stratified random sample survey of 501 high school students living in Tokyo, we find that mobile phone e-mail is used both to bond and bridge, but not to break with ties. We also find that the intensity with which Japanese adolescents use mobile phone e-mail is more fundamentally a result of bridging than bonding. These findings apply both to typical users and heavy users.

Causal relationship between Internet use and social capital in Japan

Based on longitudinal data collected from a random sample panel survey, the present study found that different types of Internet usage are differentially related to social networks. The more social ties people have, the more likely they are to use personal computer (PC) email, and the use of PC email increases social ties. The results also show that the more supportive ties people have, the more they tend to use mobile phone email; however, it does not prove the use of mobile phone email increases supportive ties. However, participation in an online community is not related social networks. These findings suggest that PC email may increase the size of personal social networks, whereas mobile phone email is useful in maintaining existing strong ties which provide social support.

Personal Media Producer: A System for Creating 3D CG Animation from Mobile Phone E-mail

Mobile phone e-mail is increasingly being chosen by consumers as their primary communication tool. Messages exchanged among mobile phone users frequently contain emoticons (smileys) and emoji (pictograms). Some consumers have started to use services that add a relevant animated image to a message. Consumers will start to exchange animated messages if they are available. This paper proposes a method of generating animation sequences from plain text messages without an authoring process. This method utilizes information available in the consumer's ubiquitous computing environment to obtain necessary information not included in the original e-mail. The results of the preliminary evaluation show that a user needs around two minutes to create a one-minute animation using this method, a 3.6 times improvement in creation efficiency over that of a prior method.

Multilingual disaster information system: information delivery using graphic text for mobile phones

A multilingual disaster information system (MLDI) has been developed to overcome the language barrier during times of natural disaster. MLDI is a web-based system that includes templates in nine languages so that translated texts can be made available immediately. Mobile phone e-mail with graphic text is a useful tool for delivering multilingual disaster information. The visibility of graphic text on mobile phones was measured and found to be equivalent to the built-in font. However, visibility deteriorates as the character size becomes smaller, especially, on displays with poor resolution. This article also discusses the necessity of multilingual information and measures for a safe and barrier-free society.
