Purpose: The aim of the study was to identify the effects of education from using cellular phones and a short messaging service. Methods: Collected data included baseline demographics, blood pressure, abdominal circumference, total cholesterol, body mass index and health behavior index (Dietary Practice Guidelines Score, Physical Activity, Drinking frequency, Stress score, Subjective health status, and Action change stage score). Data were collected at public health centers in Chungcheongnam-do from January to December, 2011. Data obtained from Individual health counseling Programs in Chungcheongnam-do. Analysis was divided into health risk group and Disease management group, using a paired t test. Results: Following the education of using short messaging service of cellular phones Health risk group was a reduction in the systolic blood pressure, diastolic blood pressure, waist circumference. Disease management group was a reduction in the systolic blood pressure and body mass index. In both groups, there were improvement in the Health behavior index; dietary practice guidelines score, physical activity, stress score, subjective health status and action change stage scores. Conclusion: These results indicated that education using short messaging service of cellular phone for Community was effective in improving health behaviors and status. By applying the results, development of customized teaching messages for stable settlement is required.

기존의 가정용 건강측정기는 기기만이 독립적으로 사용되거나 기기로부터 생체정보를 전송 받아 로컬 컴퓨터에서만 처리하는 시스템이 주를 이루었다. 본 논문에서는 가정용 건강측정기 중 혈당측정기를 적외선 통신(Infrared Communication, IrDA)으로 PocketPC에 연결하여 혈당정보를 전송받는다. 이러한 정보를 PocketPC용 CDMA(Code Multiple Access) 확장 팩을 이용하여 문자메시지(Short Message Service, SMS)로 다른 휴대폰에 전송하고, 무선 랜(WLAN, IEEE 802.11)을 이용하여 웹서버에 있는 게시판에 건강측정정보를 자동 등록 하여 정보를 공유할 수 있는 시스템을 구축하였다. 특히 비공개된 혈당측정기의 프로토콜을 분석하여 통신에 사용하였으며, API(Application Programming Interface)를 제공하지 않는 CDMA 확장팩 시스템의 사용자용 프로그램을 IPC(Inter Process Communication)를 이용한 제어를 통해 필요한 태스크를 수행하는 기법을 사용하였다.

돼지의 상태에 따라 자궁내 온도는 변화하게 되는 데 특히 수정 적기에는 특징적으로 변하게 된다. 수정적기는 자궁내 온도가 최고점인 40도 정도까지 상승했다 하강하는 때이다. 자궁내온도의 변화는 저전력 소모를 위해 제작된 무선센서를 부착하여 유비쿼터스 센서 네트워크를 통해 지속적으로 관찰한다. 유비쿼터스 센서 네트워크는 무선센서가 사용자의 컴퓨터에 설치된 수신기 및 서버로 온도변화 데이터를 보내주며 서버는 SMS 서버를 이용하여 사용자의 핸드폰에 문자 메시지를 보내준다. 사용자의 휴대폰에 수정적기에 메시지를 보내줌으로서 소득증대에 기여 할 뿐만 아니라 돼지 생육에 좋은 환경을 제공할 수 있다.

The purposes of this study were to examine effective variables influencing on adolescents' mobile phone addiction. The subjects were the 666 middle or high school students who had their own mobile phone in Gwangju. Data were analyzed with frequency, percentage, cronbach's ${\alpha}$, mean, SD, pearson's correlation and multiple regression using SPSS/PC WIN 14.0 program. The major findings were as follows: 1. The most frequently used function of student mobile phones was text message and they used text message more than 41 times a day. Mostly they were talking to the same sex friends on the phone and the monthly charges ranged from 20,000 to 30,000 won. In general, they called to their friends after school. Their parents' attitudes toward their mobile phone using showed that the most of their parents did not care about their children's mobile phone use. The restriction of using their mobile phone at school was normal. 2. The average scores of mobile phone addiction were lower than median(3.0) and self esteem, self control, family strengths, peer conformity and school life adaptation were higher than median. 3. The adolescence's mobile phone additions were influenced by peer conformity, school life adaptation, school levels, sex and self control. And these variables explained to the adolescence's mobile phone additions about 28%.

Some spoken word errors that violate grammatical or writing rules occurs frequently in communication environments like mobile phone and messenger. These unexpected errors cause a problem in a language processing system for many applications like speech recognition, text-to-speech translation, and so on. In this paper, we proposed and implemented an automatic correction system of ill-formed words and word spacing errors in SMS sentences that has been the major errors of poor accuracy. We experimented three methods of constructing the word correction dictionary and evaluated the results of those methods. They are (1) manual construction of error words from the vocabulary list of ill-formed communication languages, (2) automatic construction of error dictionary from the manually constructed corpus, and (3) context-dependent method of automatic construction of error dictionary.

현대 사회에서 휴대폰은 더 이상 문자 메시지를 송수신하거나 통신을 위한 매개체가 아니라 이동 중에도 인터넷 검색 또는 대용량 데이터를 전송하는 용도로 쓰인다. 특히 통신사에서 제공하는 서비스를 통한 모바일 인터넷 뉴스 기사 검색은 현재 효율성과 주관적 만족도가 떨어진다. 이에 본 연구는 목록 제시 방식이 모바일 브라우징 사용성에 미치는 영향을 보고자 하였다. 따라서 정보 제공의 완전성과 정보 제공의 지연 여부의 2 가지 측면으로 목록 제시 방식을 구분하였다. 탐색 과제를 통한 목록 제시 방식 효과를 비교한 결과 정보 제공이 완전하면서 지연이 없는 레이어드 팝업 조건에서 사용성과 지각된 사용성이 가장 높았으며 정보 제공이 완전하나 정보의 지연이 있는 동적 제시 조건, 정보 제공이 불완전하나 지연이 없는 ‘…’ 조건 순으로 나타났다. 그러나 레이어드 팝업 조건과 동적 제시 조건 간의 유의미한 사용성 차이는 발견되지 않았다. 이 결과는 정보의 지연 여부보다 정보 제공의 완전성이 모바일 브라우징에 더 큰 영향을 준다는 것을 시사한다. 본 연구의 결과는 상이한 디스플레이 방식들 간의 차이만을 살펴보는 수준을 넘어서 현재 적용되고 있는 WAP 서비스의 한계점을 보완하여 사용성을 향상시킬 수 있는 방안을 구축하였음에 의의가 있다.

A sow has a characteristic changing in its temperature. It is a suitable time that is decreasing after sow's body temperature increased to the highest point. We observe the variation of temperature through USN(Ubiqutous Sensor Network) system using wireless sensor inserted in the womb. The wireless sensor send massage to user's server and its server send SMS massage to user's cell phone. We contribute to user's income increase as it notice to suitable fecundation.

Short message service (SMS) is one of the most important communication methods for people who use mobile phones. However, illegal advertising spam messages exploit people because they can be used without the need for friend registration. Recently, spam message filtering systems that use machine learning have been developed, but they have some disadvantages such as requiring many calculations. In this paper, we implemented a spam message filtering system using the set-based POI search algorithm and sentence similarity without servers. This algorithm can judge whether the input query is a spam message or not using only letter composition without any server computing. Therefore, we can filter the spam message although the input text message has been intentionally modified. We added a specific preprocessing option which aims to enable spam filtering. Based on the experimental results, we observe that our spam message filtering system shows better performance than the original set-based POI search algorithm. We evaluate the proposed system through extensive simulation. According to the simulation results, the proposed system can filter the text message and show high accuracy performance against the text message which cannot be filtered by the 3 major telecom companies.

As the number of elderly people living alone has been increasing in the recent years, systems for their safety have been required, and some related services or pilot systems have been operating. These systems provide the monitoring service for the activities of the elderly people living alone with indoor location tracking technology using the various sensors. However, most systems provide services on expensive infrastructure such as attached tags and mobile devices. In this point, this paper attempts to suggest a system based on low cost sensors to collect event data in home environment. And a main characteristic of the system is that people can monitor the results of provided services through web browser in real time and the system can provide related context information to guardians and health care managers through SMS of mobile phone.

With the rapid evolution of the Internet and mobile environments, text including spelling errors such as newly-coined words and abbreviated words are widely used. These spelling errors make it difficult to develop NLP (natural language processing) applications because they decrease the readability of texts. To resolve this problem, we propose a spelling error correction model using a spelling error correction dictionary and a newspaper corpus. The proposed model has the advantage that the cost of data construction are not high because it uses a newspaper corpus, which we can easily obtain, as a training corpus. In addition, the proposed model has an advantage that additional external modules such as a morphological analyzer and a word-spacing error correction system are not required because it uses a simple string matching method based on a correction dictionary. In the experiments with a newspaper corpus and a short message corpus collected from real mobile phones, the proposed model has been shown good performances (a miss-correction rate of 7.3%, a F1-measure of 97.3%, and a false positive rate of 1.1%) in the various evaluation measures.
