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: 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: 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.
