Judul: Evaluation Of Leukocyte Profile In Piglet (Sus Scrofa) During The Recruitment Maneuver On Pediatric Acute Lung Injury Model
Abstrak: This study evaluated the recruitment maneuvers effectiveness in piglet as model for pediatric acute lung injury (PALI). Leukocyte differentiations were observed as parameter. Six piglets in 5-8 kg weight range were divided in two groups. Three piglets as the first group without chest bandaging (A) and three piglets as the second group with chest bandaging (B). Chest bandaging in B group used as model for undeveloped diaphragm in infants. Recruitment maneuver was performed after induced acute lung injury by lavaging warm saline into lung parenchymal. Samples were taken at screening stage and postrecruitment maneuver within 95% confidence level. The results showed non-significant increase of the percentage of neutrophils and non-significant decreases of the total leukocytes, percentage of eosinophils, lymphocytes, and monocytes in both treatment groups. The increase and decrease level was bigger in the chest bandaging group.

Judul: Evaluasi Ekokardiografi Anak Babi (Sus scrofa) Selama Manuver Rekrutmen pada Model Cedera Paru Akut Pediatri
Abstrak: The aim of this study was to evaluate echocardiography in piglet (Sus scrofa) after induced acute lung injury (ALI). Eight piglets 1-3 months in age with body weight 5-8 kgs were divided into two groups. The first group received recruitment maneuver without chest bandaging (BTB) and the second group with chest bandaging (BB). Recruitment maneuver was performed after induced ALI by lavaging warm Saline 0.9% into lung parenchymal. Chest bandaging is a model of unfully developed diaphragm in infants. Echocardiography was performed by measuring the M-mode image on the right parasternal short axis view on papillary muscle level. Samples were taken at an early stage (screening) were used as the normal value and at post-recruitment. The results of this study showed preload decreased in left ventricular after recruitment maneuver. The evaluation results of echocardiography had worse at BB group. BB group was significantly decreased (p<0.05) in heart rate (HR) and cardiac output (CO). Hence, recruitment maneuver had worse effect to the ALI pediatrics with unfully developed diaphragm.

Judul: Cycle Hamilton pada Graf Lengkap, Graf Regular, dan Graf 2-Connected 4-Regular Berorder Kurang dari Sepuluh
Abstrak: Suatu graf disebut graf Hamilton apabila graf tersebut memuat cycle Hamilton, yaitu cycle yang melewati setiap vertex tepat satu kali. Menentukan keberadaan cycle Hamilton pada suatu graf dapat menggunakan syarat cukup yang berupa teorema-teorema yang telah diperkenalkan sejak tahun 1950-an. Beberapa syarat cukup yang dibahas dalam karya ilmiah ini adalah syarat cukup yang berhubungan dengan graf lengkap dan graf regular. Suatu graf lengkap berorder 𝑛������ ≥ 3 dan graf r-regular berorder 𝑛������ ≤ 2𝑟������ + 1 merupakan graf Hamilton, Karena kedua graf tersebut memuat cycle Hamilton. Selanjutnya, syarat cukup tersebut digunakan untuk menentukan keberadaan cycle Hamilton pada graf 2-connected 4- regular berorder kurang dari 10.
