Disaster alerts are text messages sent by government to people in the area in the event of a disaster. Since the number of disaster alerts has increased, the number of people who block disaster alerts is increasing as many unnecessary disaster alerts are being received. To solve this problem, this study proposes a deep learning model that automatically classifies disaster alerts by disaster type, and allows only necessary disaster alerts to be received according to the recipient. The proposed model embeds disaster alerts via KoBERT and classifies them by disaster type with LSTM. As a result of classifying disaster alerts using 3 combinations of parts of speech: [Noun], [Noun + Adjective + Verb] and [All parts], and 4 classification models: Proposed model, Keyword classification, Word2Vec + 1D-CNN and KoBERT + FFNN, the proposed model achieved the highest performance with 0.988954 accuracy.

The purpose of this study is to examine the mobile phone service usage patterns of Korean teenagers and their motivation to use it, and to explore the relationships between the teenagers' social-psychological characteristics and their trails of mobile phone usage. After reviewing prior theoretical studios, three hypotheses regarding the research questions shown above were generated. Questionnaire study was conducted with 400 high school students in Busan and Ulsan metropolitan areas. They were to answer three categories of questions, such as frequencies of voice calls and text messaging services and the other mobile services, questions asking their social-psychological characteristics, and their motivations for using mobile phone services. Findings show that the teenagers more likely to tend to use voice calls when communicating family members. They tend to avoid those services with high rate of use as multimedia, game, and broadcasting services via mobile phones. The teenagers use mobile phone services for the similar purposes to conventional telephone uses. Therefore, the classical theories showing the alternative purposes or motivations to use conventional telephone usage, which divided the main purposes for phone uses in to two; work/instrumental and socializing/entertaining, proved to be reasonable. The cheap messaging services with texts are popular among the teenagers and are used for socializing/entertaining purposes rather than instrumental/functional purposes. In addition, the teenagers' social-psychological characteristicss are significantly associated with the amount of mobile phone uses. A characteristic of "individual-centeredness" is positively related with non-voice service uses, while "group-centeredness" explains heavy amount of using voice calls and text messaging services. Such characteristics as "immediacy," "directness," "innovativeness," and "other-direction" are positively associated with the frequencies and amounts of mobile phone uses, while "inner-direction" and "tradition-direction" are negatively correlated.

휴대전화의 보급에 따라 문자 서비스가 대중에 보급되었고, 인터넷의 발전에 따라 인터넷 전화기의 사용이 보편화되면서 이를 이용해서 문자를 주고 받을 수 있다. 사내에서도 비용을 절감하기 위해서 IP-PBX(Internet Protocol Private Branch Exchange) 장비를 이용해 IP폰으로 음성통화나 문자 서비스를 제공 받을 수 있다. 현재 IP-PBX 시스템 상에서 또는, IMS망끼리만 메시지를 주고 받을 수 있었지만 IP-PBX와 IMS망을 연동하는 방법은 없었다. 따라서 본 논문에서는 IMS망과 IP-PBX와 연동해서 메시징 서비스를 제공하는 방법에 대해 제안하였다.

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.

In this paper, a detection technique of smishing using a TaintDroid is suggested. Suggesting system detects malicious acts by transmitting a URL to the TaintDroid server and installing a relevant application to a virtual device of the TaintDroid server, when a smartphone user receives a text message including the URL suspected as a smishing. Through this we want to distinguish an application that can not install because of suspicion of a smishing in an actual smartphone whether said application is malicious application or not by testing with the virtual device of said system. The detection technique of a smishing using the TaintDroid suggested in this paper is possible to detect in a new form a smishing with a text message and to identifying which application it is through analysis of results from a user.

Purpose: The purpose of this study was to investigate the effect of a short message service intervention on adherence to maximal barrier precautions (MBP) and catheter-related blood stream infections. Method: The data were collected from March to September, 2008, at an 826-bed university-affiliated hospital in Daejeon. The study participants were 24 physicians who were inserting central catheters and 133 patients (control group 78 and intervention group 55) with central catheter insertions. The researcher sent the message (adherence to MBP and optimal recommendations) to each internal medicine doctor using the short message service (SMS) for cellular phones. Messages were sent monthly for 3 months. Data were analyzed by chi-square test and t-test using SPSS 12.0 windows program. Result: Adherence to maximal barrier precautions was significantly increased from 44.9% to 69.1% (p=.006) after the SMS intervention. But changes in the rate of CRBSI (catheter related blood stream infection) between the intervention group (1.89) and the control group (4.45) were not significant (p=.323). Conclusions: The results indicate that the SMS intervention is effective in increasing the adherence to maximal barrier precautions and the SMS intervention can be recommended for utilization in infection control nursing practice.
