Judul: Evaluasi Radiografi Toraks Anak Babi (Sus scrofa) sebagai Hewan Model dalam Manuver Rekrutmen Cedera Paru Akut Pediatri.
Abstrak: Studi dilakukan untuk menganalisis perubahan pada paru-paru manuver rekrutmen anak babi yang diinduksi cedera paru akut (CPA) sebelum manuver rekrutmen (praperlakuan) dan setelah manuver rekrutmen (pascamanuver). Ada sepuluh ekor anak babi diinduksi CPA dengan melakukan kumbah bronkus menggunakan NaCl 0.9%. Anak babi dibagi menjadi dua kelompok, kelompok pertama dilakukan manuver rekrutmen tanpa pembebatan di dada (nonbebat) dan kelompok kedua dilakukan manuver rekrutmen dengan pembebatan di dada (bebat). Hasil menunjukkan pada kedua kelompok perlakuan ditemukan perubahan radiografi yaitu pola intertsisial berupa peribronchial pattern, pola alveolar berupa cotton-like density, air bronchogram, edema pulmonum dengan tipe nonkardiogenik dan tidak ditemukannya gambaran dilatasi vena pulmonalis. Gambaran perubahan antara kelompok bebat dengan nonbebat tidak ada perbedaan.

Judul: Interpretasi Radiografi Jantung Anak Babi (Sus Scrofa) pada Manuver Rekrutmen Cedera Paru Akut Pediatri
Abstrak: This study was conducted to evaluate cardiovascular radiography (vertebrae heart score (VHS) and cardiothoracic ratio (CTR)) during recruitment maneuver after induced acute lung injury (ALI) in piglet as animal model. As many as ten piglets used on this study. Condition of ALI were induced by lavaging prewarmed saline into lung parenchymal. Recruitment maneuver performed into two groups. The first group (RmB) was bandaged on their chest during recruitment maneuver while the second group (Rm) was not. Chest bandaging is simulated abnormalities of diaphragm muscle in baby. Samples were taken before and after recruitment maneuver. On right lateral view showed that, angle of heart value were ranged between 28.28-34.83o and VHS value increase in RmB greater than Rm. This is happened because chest bandaging provided additional intrathoracic pressure. On Dorsoventral view, CTR value between groups still in the normal range. RmB as a model pediatric musculoskeletal disorders showed significant disturbance in right heart has showed increase short axis value. Rm showed no significant abnormalities. Intrathoracic pressure agreeged heart contractility by enlarging right heart chamber during recruitment maneuver.

Judul: Construction of Strongly Optimal Binary Linear Code with Minimum Distance 9 and 11
Abstrak: A binary linear code of length n over q F is a subspace of n q F . A code has three parameters that attached to it, namely length, dimension, and minimum distance. A code with length n, dimension k and minimum distance d is often called [n, k, d ]-code. Usually, when two parameters are given, then we want to find a code that has the best value for the last parameter. Based on Gilbert- Varshamov bound, if a [n, k, d ]-code exists and can not be expanded, we call it a strongly optimal code. In this paper, we construct strongly optimal code with minimum distance 9 and 11. In constructing the code, we created a theorem and algorithm based on Gilbert-Varshamov bound before we implement the algorithm to MAPLE programming language. Because of computational limitations, the program can only construct up to k = 10 for d = 9 and k = 12 for d = 11.
