At present, content-based methods are regard as the more effective in the task of Short Message Service (SMS) spam filtering. However, they usually use traditional text classification technologies, which are more suitable to deal with normal long texts; therefore, it often faces some serious challenges, such as the sparse data problem and noise data in the SMS message. In addition, the existing SMS spam filtering methods usually consider the SMS spam task as a binary-class problem, which could not provide for different categories for multi-grain SMS spam filtering. In this paper, the authors propose a message topic model (MTM) for multi-grain SMS spam filtering. The MTM derives from the famous probability topic model, and is improved in this paper to make it more suitable for SMS spam filtering. Finally, the authors compare the MTM with the SVM and the standard LDA on the public SMS spam corpus. The experimental results show that the MTM is more effective for the task of SMS spam filtering.

With the overflowing of Short Message Service (SMS) spam nowadays, many traditional text classification algorithms are used for SMS spam filtering. Nevertheless, because the content of SMS spam messages are miscellaneous and distinct from general text files, such as more shorter, usually including mass of abbreviations, symbols, variant words and distort or deform sentences, the traditional classifiers aren't fit for the task of SMS spam filtering. In this paper, the authors propose a Short Message Biterm Topic Model (SM-BTM) which can be used to automatically learn latent semantic features from SMS spam corpus for the task of SMS spam filtering. The SM-BTM is based on the probability of topic model theory and Biterm Topic Model (BTM). The experiments in this work show the proposed model SM-BTM can acquire higher quality of topic features than the original BTM, and is more suitable for identifying the miscellaneous SMS spam.

The study was conducted to examine the effect of Short Message Service (SMS) Texting on medication adherence among tuberculosis patients. 68 persons diagnosed with tuberculosis and registered in the public health center in Klari, Karawang, West Java, Indonesia, were randomly appointed to an experimental or control group; 34 persons assigned to each group. Participants in the experimental group received routine SMS Texting, while those in the control group receive none. Data were analyzed using Dependent t-test and Independent t-test. The results indicated that after participating by receiving SMS texting, there was a significant improvement in medication adherence in TB patients in the experimental group, which was shown by significant difference in mean score of medication adherence. In addition, after participating in the program, there was a meaningful difference in mean scores of medication adherence between the experimental group (X=6.38, SD=0.85) and the control group (X=3.64, SD=1.04), p<0.01. The SMS Texting method appears to be effective in improving medication adherence among TB patients.

Anemia merupakan salah satu penyebab terjadinya perdarahan dan bisa mengakibatkan kematian pada ibu hamil. Suplementasi besi merupakan program pemerintah dalam mengatasi anemia pada wanita hamil dan beberapa wanita hamil masih ada yang belum patuh dalam mengkonsumsi tablet besi. Oleh karena itu, diperlukan sebuah metode yang bisa meningkatkan kepatuhan wanita hamil dalam mengonsumsi tablet besi yaitu dengan short message service (SMS) reminder. Penelitian ini bertujuan untuk mengidentifikasi efektivitas SMS reminderterhadap kepatuhan konsumsi tablet besi pada ibu hamil di (unit pelayanan terpadu) UPT Puskesmas Cibuntu Kota Bandung. Rancangan penelitian quasi experimentaldengan desain posttest-only with control group designdengan teknik pengambilan sampel yang digunakan adalah purposive sampling. Penelitian ini dilaksanakan dari bulan April–Mei tahun 2014 di Puskesmas X Kota Bandung. Sampel berjumlah 40 orang wanita hamil yang tidak patuh dalam mengonsumsi tablet besi yang dibagi menjadi 20 kelompok intervensi dan 20 kelompok kontrol. Data diperoleh melalui kuesioner dalam bentuk self report.Analisis data yang digunakan adalah analisis deskriptif dan uji chi square. Hasil penelitian menunjukkan sebagian besar kelompok intervensi 17 orang (85%) patuh dan sebagian besar kelompok kontrol 16 orang (80%) tidak patuh. Hasil analisis dengan menggunakan chi squaredidapatkan p(0.000) dengan taraf signifikan <0.05 sehingga dapat disimpulkan bahwa SMS reminder efektif terhadap kepatuhan konsumsi tablet besi pada wanita hamil dan bisa dijadikan bahan pertimbangan bagi pihak Puskesmas untuk menjalin kerjasama dengan pihak provideratau mengajukan dana ke Dinas Kesehatan untuk mengaktifkan SMS reminderdi Puskesmas.Kata kunci: Kepatuhan, SMS reminder,tablet besi, wanita hamil AbstractAnemia is one of the leading causes of hemorrhage during pregnancy, and it can cause death to expectant mothers. Iron supplementation is a government program to overcome anemia among expectant mothers, and some of the expectant mothers still do not obediently consume iron tablets. Therefore, to increase the obedience of the expectant mothers on consuming the iron tablets, SMS reminder is the appropriate method needed. This research aims to identify the effectiveness of SMS reminder to the obedience of iron tablets consumption among expectant mothers at UPT Puskesmas Cibuntu , Bandung. The research employed quasi-experimental design with posttest-only control group design using purposive sampling technique. The research was held on April–May 2014 at UPT Puskesmas Cibuntu, Bandung. Forty expectant mothers consuming iron tablets disobediently divided into 20 intervention groups and 20 control groups were taken as the samples. Questionnaire in form of self report was used to obtain data. In addition, descriptive analysis and chi square test were applied to analyze the data. The result of the research showed that 17 persons (85%) of intervention groups were mostly obedient, and 16 persons (80%) of control groups were mostly disobedient. From the analysis using chi square, it was found the difference of the obedience of iron tablets consumption after SMS reminder (p=0.00) had been delivered with significant level <0.05. Based on the result of this research, SMS reminder had an effective impact toward the obedience of iron tablets consumption among the expectant mothers. The result will be a good consideration for Puskesmas to cooperate with provider or proposed some funds to Dinas Kesehatan to activate SMS reminder.Key words:Expectant mothers, obedience, SMS reminder, iron tablets

Kemajuan perkembangan teknologi komputer dan telekomunikasi dapat membantu menyelesaikan pekerjaan dengan cepat, akurat dan efisien. Alat komunikasi yang banyak digunakan pada saat ini adalah mobile phone atau disebut juga telepon seluler. Salah satu teknologi yang digunakan untuk berkomunikasi pada mobile phone adalah dengan mengirimkan data berupa pesan singkat atau SMS (Short Message Service). Permasalahan yang ditemukan dalam berkomunikasi menggunakan mobile phone adalah pencurian, penyadapan, atau penghapusan data khususnya data SMS (Short Message Service) sehingga aspek keamanan data dianggap penting. Oleh karena itu dibutuhkan sistem kriptografi enkripsi dan dekripsi SMS, disini digunakan enkripsi simetris. Sistem ini merupakan aplikasi yang menerapkan metode zig zag cipher yang menggunakan kunci simtetris. Hasil pengujian dari sistem ini adalah pesan SMS dienkripsi dengan pola zig zag menggunakan kunci dan didekripsi menggunakan kunci yang sama dengan enkripsi.
