Purpose: This study was conducted to investigate the effects of preparatory nursing information and information offering by SMS on anxiety and nursing satisfaction among family members of ICU (Intensive Care Unit) inpatients. It utilized a quasi-experimental research design with a non-equivalent and non-synchronized control group. Methods: The experimental group and the control group were offered a booklet guiding ICU and were offered face-to-face information by nurses using Power Point. The experimental group was additionally offered SMS (short message service) message on patient's safety at night every morning during the hospital stay between 8 and 9 am. All participants in the experimental group and the control group were measured in reference to anxiety at the point of hospitalization and were surveyed anxiety and nursing satisfaction on the third day of hospital stay. Results: The anxiety demonstrated no significant difference between the groups, while the nursing satisfaction was significantly higher in the experimental group than that of the control group. Conclusion: Proving direct information and indirect information via SMS message were considered effective in improving the family member's satisfaction with nursing care. The frequencies of SMS message and the contents of the message and information need to be defined and specified in the given population.

Many Web sites adopt SMS(Short Message Service)-based user authentication when a user loses her password or approves an online payment. In SMS-based authentication, the authentication server sends a text in plaintext to a user's phone, and it allows an attacker who eavesdrops or intercepts the text to impersonate a valid user(victim). We propose a challenge-response scheme to prove to the authentication server that a user is in a certain place at the moment with her smartphone beside her. The proposed scheme generates a response using a challenge by the server, user's current location, and a secret on the user's smartphone all together. Consequently, the scheme is much more secure than SMS-based authentication that simply asks a user to send the same text arrived on her phone back to the server. In addition to entering the response, which substitutes the SMS text, the scheme also requests a user to input a passphrase to get the authentication process started. We believe, however, the additional typing should be tolerable to most users considering the enhanced security level of the scheme.

Purpose: The purpose of this study was to investigate the effect of the SMS(Short Message Service) informing patients' surgical operation status to his or her family members on their nursing satisfaction. Methods: A non-equivalent control group non-synchronized design was used. The subjects were the family members of patients underwent spine surgery operation at a general hospital in B city. Twenty five subjects in the experimental group received SMS services whereas the other twenty five subjects in the control group received no intervention. Results: There was a significant difference in the level of nursing satisfaction in the experimental group compared to that of the control group(t=7.14, p=.001). Conclusion: The result above indicates that the level of nursing satisfaction of family members of the patients under surgical operation can be raised by providing SMS informing surgical operational status during the operation. This finding leads to the conclusion that such information service can be used as one of the efficient interventions for improving patient and family satisfactions with nursing care in a surgical unit.

Background: Stomach cancer is one of the five most common cancers in Iran. This study examined the effectiveness of a mobile telephone short-message service (SMS) based-education intervention using Health Belief Model (HBM) variables in improving dietary behavior in terms of stomach cancer prevention among a sample of Iranian female college students. Materials and Methods: In this quasi-experimental study, 124 female college students in the dormitories of Yazd University, Yazd, Iran were randomly selected and assigned to either the intervention (n=62) or the control group (n=62). Information (data) regarding HBM variables and dietary behavior related to stomach cancer prevention was collected by a self-administrated questionnaire. Forty eight messages were designed and sent to the participants' phones in the intervention group during the 48-day intervention period. Two groups were followed-up one month after the intervention delivered via SMS. Results: There were significant differences in HBM variables (except for the perceived severity) and the preventive dietary behaviors for stomach cancer in the intervention group compared to the comparison group following the education intervention delivered via SMS. Conclusions: SMS-delivered nutrition education intervention can be a practical strategy to improve dietary behavior related to stomach cancer prevention.

In this paper, a new cm (Caller ID) transceiver is introduced for SMS(Short Message Service) and e-mail services by the wire and digital cordless phones in 900MHz like as mobile phones. For this wireless digital cm phone, improved radio transceiver modules is proposed and implementedusing the analysis of data processing errors. As a result, many wireless cm services can be popular without the kind of switching systems.

Purpose: The purpose of this study was to determine the effects of self-care program using Short message service (SMS), e-mail, or telephone call on self-care compliance and nutritional status in maintenance of hemodialysis patient. Methods: Nonequivalent pretest-posttest control experimental design was used. Ninety-six patients were allocated to control (n=24), SMS (n=24), e-mail (n=24), or telephone (n=24) group from four hospitals. Experimental groups received self-care program about hemodialysis diet, drug administration, exercise, and fistula care by SMS, e-mail, or telephone call respectively at 3 times a week for 4 weeks. Results: Subjective self-care compliance, and objective self-care compliance including interdialytic weight of SMS and telephone groups were significantly increased than those of control groups. However, nutritional status of SMS and e-mail groups were significantly improved than those of control groups in albumin and protein level. Conclusion: Self-care program using SMS and telephone call were effective on promoting self-care compliance, while SMS and e-mail were effective on improving nutritional status. The pop-up remaining effect and easy accessible effect of SMS message in busy daily life was considered as an alarm to control fluid and diet.

Short message service(SMS) in a mobile communication environment is a very convenient method. However, it caused a serious side effect of generating spam messages for advertisement. Those who send spam messages distort or deform SMS sentences to avoid the messages being filtered by automatic filtering system. In order to increase the performance of spam filtering system, we need to recover the distorted sentences into normal sentences. This paper proposes a method of normalizing the various types of distorted sentence and extracting keywords through automatic word spacing and compound noun decomposition.

General customer uses internet, SMS(Short Message Service), ATM(Automated Teller Machine), DM(Direct Mail), and telephony services, etc, for service of big businesses and small and medium enterprises, securities, financial institutions, bank. In particular, the case of Fire insurance & Securities, financial institutions, banks must meet Real-Time constrain control through QoS(Quality of Service) ensure. In this paper, we design and implement a system model about Fault-Tolerance IVR(Interactive Voice Response) of Multi Channel Service based on CRM(Customer Relationship Management) environment for the first inbound position of customer. The proposed model can be widely used in Large-scale Customer Response service.
