Abstract

Puasa preoperatif merupakan keharusan sebelum dilakukan tindakan anestesi. Alasan utamanya adalah untuk mengurangi volume lambung, tingkat keasaman lambung, dan mengurangi risiko aspirasi paru. Namun, puasa preoperatif sering kali lebih lama daripada yang direkomendasikan karena berbagai sebab. Tujuan penelitian ini mengetahui durasi puasa preoperatif pada pasien operasi elektif dan hubungan antara durasi puasa preoperatif dan kadar gula darah sebelum induksi pasien operasi elektif di Rumah Sakit Dr. Hasan Sadikin Bandung. Penelitian observasional dilakukan selama 1–31 Juni 2014 dengan melakukan wawancara pasien sebelum induksi anestesi dan pengukuran kadar gula darah menggunakan glukometer. Analisis korelasi menggunakan Uji Mann-Whitney. Hasil penelitian pada 371 pasien didapatkan lama puasa dari makanan padat, durasi minimum adalah 4 jam, maksimum 20,5 jam, dan rata-rata 10,42 jam. Pada puasa dari minuman, durasi puasa minimum adalah 2 jam, maksimum 18 jam dengan rata-rata 8,06 jam. Terdapat 8 pasien dengan kadar gula darah kurang dari 70 mg/dL dengan rentang kadar gula darah 59–70 mg/dL dan rentang durasi puasa 6–18 jam. Tiga di antaranya orang lanjut usia di atas 60 tahun. Sebanyak 253 pasien berpuasa makanan padat >8 jam dan 357 pasien berpuasa minuman >2 jam. Simpulan, tidak terdapat hubungan antara durasi puasa dan kadar gula darah sebelum induksi.Kata kunci: Durasi puasa preoperatif, kadar gula darah, operasi elektifCorrelation between Preoperative Fasting Duration and Blood Glucose Level before Induction in Elective Surgery Patients in Dr. Hasan Sadikin General Hospital BandungPreoperative fasting is a requisite before anesthesia. The main reason for preoperative fasting is to reduce gastric volume and acidity and, thus, decrease the risk of pulmonary aspiration. However, preoperative fasting is usually prolonged beyond the recommended time for various reasons. Despite the many adverse effects of prolonged fasting, patients sometimes fast for a prolonged time when the surgery is delayed for different reasons. The aim of this study was to assess the duration of preoperative fasting for elective surgery and its correlation with blood glucose after preoperative fasting in Dr. Hasan Sadikin General Hospital Bandung. An observational study was conducted from 1- 31 June 2014. Patients were interviewed before induction, and blood glucose level was measured using a glucometer. A correlation analysis was performed using Mann-whitney test. All 371 elective surgery patients admitted during the study period were included. The minimum, maximum, and mean fasting hours for food were 4, 20.5, and 10.42, respectively. The minimum, maximum, and mean fasting hours for fluid were 2, 18, and 8.06, respectively. Only 8 patients had blood a glucose level below 70 mg/dL with blood glucose levels range from 59 to 70 mg/dL and duration of fasting range from 6 to 18 hours. Three of elderly patients, who was above 60 years old, participated in this study. There were 253 patients (68.2%) fasted from solid food more than 8 hours and there were 357 (96.2%) fasted from clear fluid more than 2 hours. It is concluded that there is no correlation between duration of fasting and blood sugar level before induction.Key words: Duration of preoperative fasting, elective surgery, blood glucose level DOI: 10.15851/jap.v4n2.822

Abstract

Tiling is a process to create a repetitive - larger size - image. However if the picture on the left side of the original image is not continuous to the picture on its right side, the tiling image will have a virtual vertical line called seam. Meanwhile the virtual horizontal line will appear if the picture on the top side of the original image is not continuous to the picture on its bottom side. The research performed here tries to generate a seamless tiling image by finding the closest match of the fractional source image to the partially build resulted image. From the experiment, it can be shown that the quality of the resulted image are affected by the number of similar elements in the source image, the number of fractional images created from the source image, and the width of the overlap area. Source image with a lot of similar element, high number of fractional images, and wider size of the overlap area have been proven to yield a seamless tiling image.

Abstract

Original ray tracing method can be used to create picture of objects that are very similar to photographic. However for simplicity, the method mimics a pinhole camera in its model. In pinhole camera all objects visualized in the image generated will be seen sharp. In some cases, this kind of image is acceptable but in other cases it is not. For example, in the movie industry, sometimes it is preferable to get the image that can be focused to a certain object and not to all objects. This effect occurs due to the usage of a lens in a camera. In order to get the same effect to the real camera, then it is necessary to modify the original ray tracing method to use lens in its model. The research performed here has successfully simulating the effect of lens in camera. Therefore only objects that are placed in the lens focus will be seen sharp while the others will become blurry.

Abstract

Alphanumerical password is the password scheme that obligates the users to enter characters as their password. In spite of its popularity, alphanumerical password usually can be cracked easily when it is used by novice users. Since these users usually type their password slowly, unauthorized person can get the password easily by observing the movement of the users' finger as they entering the password. A graphical password is proposed to replace the alphanumerical password. From the experiment it can be shown that none of users graphical password can be cracked, meanwhile 80% of the users' alphanumerical password can be cracked by the researcher. However in average, users need only 4.68 seconds to enter the password in alphanumerical password scheme, meanwhile in graphical password scheme it takes about 39.06 seconds. Hence password entry in the graphical password scheme needs about 8 times longer than in alphanumerical password. Based on this fact, the graphical password may still be considered to be used in applications that do not need a rapid password entry and the system security is becoming the main issue.
