Judul: Electrocardiogram of Pigs (Sus scrofa domestica) as Animal Model Candidate of Artificial Myocardial Infarction
Abstrak: Penelitian ini bertujuan mengetahui perubahan aktivitas listrik jantung akibat infark miokardium pada hewan model babi (Sus scrofa domestica) menggunakan elektrokardiografi (EKG). Pengambilan data dilakukan pada tiga ekor babi jantan dengan umur 4-5 bulan. Perekaman data EKG dilakukan sebelum dan setelah prosedur operasi pembuatan infark miokardium pada babi. Parameter yang diamati adalah durasi P, amplitudo P, interval PR, interval QRS, amplitudo R, amplitudo T, interval QT, segmen ST, dan frekuensi denyut jantung yang direkam pada sadapan II. Data yang diperoleh dianalisis menggunakan uji paired sample T test dan dinyatakan dalam nilai rata-rata serta standar deviasi. Hasil rekaman EKG menunjukkan adanya perbedaan nyata pada parameter interval PR, gelombang T, interval QT, segmen ST, dan frekuensi denyut jantung. Hal ini menunjukkan bahwa kondisi infark miokardium mempengaruhi konduksi listrik atau aktivitas kelistrikan jantung.

Judul: Physiological Parameters of Pig (Sus scrofa domestica) Post-Induced Cardiac Infarction with Total Occlusion in Circumflex Artery
Abstrak: Penyakit kardiovaskular adalah penyebab utama kematian di dunia. Sistem kardiovaskular babi dapat digunakan dalam penelitian infark miokardium karena memiliki kemiripan anatomi dan fisiologi dengan manusia. Pemeriksaan parameter fisiologis selama pembedahan merupakan cara cepat dan efisien untuk memantau kondisi pasien, mengidentifikasi masalah, dan mengevaluasi respons pasien terhadap intervensi bedah. Penelitian ini bertujuan mengetahui parameter fisiologis terkait nilai frekuensi napas, frekuensi jantung, dan suhu tubuh 15 menit sebelum dan sesudah induksi oklusi total arteri circumflexa dengan cara ligasi pada babi. Babi yang digunakan berjumlah lima ekor dengan jenis kelamin empat jantan satu betina bobot 51–55 kg. Frekuensi napas dan jantung dipantau dari patient monitor serta suhu tubuh diukur dari termometer digital. Data yang diperoleh diolah secara deskriptif. Frekuensi napas dan frekuensi jantung 15 menit pascainduksi infark miokardium menunjukkan rata-rata terjadinya penurunan tetapi masih berada dalam rentang nilai normal, sedangkan suhu tubuh menunjukkan hasil lebih rendah dari rentang nilai normal meskipun terjadi peningkatan. Hal ini diduga disebabkan perubahan fisiologis, aktivitas saraf, dan hormon., Cardiovascular disease is the leading cause of death in the world. Swine cardiovascular system can be used in the study of myocardial infarction because it has anatomical and physiological similarities to humans. Physiological parameters examination during surgery is a quick and efficient way to monitor the patient's condition, identifying problems, and evaluate the patient's response to surgical intervention. This study aims to determine the physiological parameters related to the value of respiratory rate, heart rate, and body temperature 15 minutes before and before induction of total occlusion of the circumflex artery by ligation in pigs. The number of pigs used were five with the sex of four males and one female weighing 51–55 kg. Respiratory and heart rates were monitored from the patient monitor and body temperature was measured from digital thermometer. Obtained data were processed descriptively. The respiratory and heart rate 15 minutes after the induction of myocardial infarction showed an average decrease within the normal range, while body temperature showed a lower result than the normal value range despite an increase. This has been thought due to physiological changes, neural activity, and hormones.

Judul: Query Expansion based on Bilingual Dictionary Using Conditional Probability
Abstrak: Query expansion is a technique that can be used to bridge vocabulary gaps between queries and documents in the collection. With query expansion, user will be helped to formulate queries well so that user will optimize the search result. In this study, the expansion term was resulted from the translation of bilingual dictionary. Subsequently, several terms of expansion were elected based on the closeness of its relationship with the original query. This research showed that conditional probability can be used to select expansion term in bilingual translation method query expansion. The result of 1000 documents was more than 97% relevan document can be retrieved by this system. The more expansion term used, the larger number relevan document was retrieved.
