Judul: Studi Kasus Patologi Hernia Diafragmatika pada Kucing
Abstrak: A cat was found with several critical conditions such as skin ulceration, exophthalmus, anorexia, cachexia, dyspnoe, anemia, constipation, and severe dehydration. The cat was well-treated with some medications but it failed. Radiographs show that diaphragm line was not seen with some abdominal contents displacement into the thoracic cavity. Necropsy study revealed many lesions in characteristic of congenital diaphragmatic hernia due to diaphragm anomalies. Histopathologically, congestion and other lesions were found in heart, lungs, liver, kidneys, spleen, lymph node, and brain. Those lesions were found due to negative pressure effect which moved the intestine and a part of liver into the thoracic cavity. Therefore, the heart and lungs could not work normal then consequence of the death was caused by congestive heart failure.

Judul: Studi Kasus Perbaikan Traumatic Diaphragmatic Hernia pada Kucing di Pet First Veterinary Centre, Kuala Lumpur, Malaysia
Abstrak: Traumatic diaphragmatic hernia is an injury to the thorax in which the forces applied to the diaphragm exceed the diaphragmatic holding strength, resulting in a defect that allows abdominal contents to protrude into the thoracic cavity. This case research aimed to investigate diaphragmatic hernia treatment and surgical repair. The patient is a 1-year old, female domestic short hair (DSH) cat, black-white hair with a body weight of 2.8 kg. Pet First Veterinary Center monitored clinic symptoms and diagnostic data before surgery. Patient state was closely checked. The loss of the ventral border of the diaphragm and the displacement of abdominal viscera within the thorax are the most prominent radiological features in patient with diaphragmatic hernias. Surgery was performed at Pet First Veterinary Centre to restore negative pressure in the thoracic cavity by thoracocentesis. Diaphragmatic hernia repair involved reconstructing the diaphragm to restore its original function. Intermittent positive pressure ventilation (IPPV) was performed in this surgery. The treatment with corrective surgery was recorded, followed by the recovery of the patient within one month of the surgery. This research demonstrated that diaphragmatic hernia repair was an effective method of treatment for diaphragmatic hernia to preserve pulmonary function., Hernia diafragma traumatis adalah cedera pada toraks akibat adanya gaya pada diafragma yang melebihi kekuatan diafragma untuk menahan tekanan. Penelitian bertujuan mengetahui cara pengobatan dan teknik pembedahan kasus hernia diafragma traumatis pada kucing. Pasien adalah kucing domestic short hair (DSH) betina berumur 1 tahun berbulu hitam putih dengan berat badan 2,8 kg di Pet First Veterinary Center. Studi kasus dimulai dengan pemeriksaan fisik untuk melihat gejala klinik dan melihat data diagnostik sebelum operasi. Hilangnya batas ventral diafragma dan bergesernya organ abdomen ke rongga toraks menjadi gambaran radiologis yang terlihat pada pasien penderita hernia diafragmatika. Pembedahan dilakukan di Pet First Veterinary Center untuk memulihkan tekanan negatif di rongga toraks dengan thoracocentesis. Diaphragmatic hernia repair merupakan teknik pembedahan untuk mengembalikan fungsi diafragma. Intermittent positive pressure ventilation (IPPV) merupakan teknik ventilasi yang membantu pasien agar dapat bernapas optimal selama proses bedah berlangsung. Perawatan post-operasi berlangsung dicatat dalam sistem rekam medik digital dan pemulihan pasien terjadi dalam waktu satu bulan. Penelitian menunjukkan bahwa diaphragmatic hernia repair adalah metode pengobatan yang efektif untuk kasus hernia diafragma traumatis sehingga dapat mempertahankan fungsi paru-paru.

Judul: Selang kepercayaan untuk koefisien B1 dari garis regresi apabila ragam galat tidak homogen dengan metode ols, wls dan bootstrap
Abstrak: Slope estimation of a regression line and its confidence interval can be constructed by OLS (Ordinary Least Squares) and WLS (Weighted Least Squares) method. Confidence interval being found by both method must satisfy assumption about normality of error term with zero mean and common variance for OLS method and heteroscedasticity for WLS method and independency of error term. NC (Nanayakkara and Cressie) method is a method aimed to reduce variance of estimate resulted from OLS method when error term has non- constant variance.
