Filipino language is an Austronesian language based on numerous native languages with influences from other major languages such as English and Spanish. The Filipino alphabet is consists of 26 English alphabets, with the addition of two letters, "$\tilde{n}$" and "ng", a total of 28 letters. Filipino language expressions and sentences are still incomparable to English and Spanish even though there are numerous borrowed words from these languages. This study aims to discover the uniqueness in the Filipino language by identifying the frequencies of the letters in common words used and be able to introduce a revolutionary keypad for the Filipinos which is scientifically efficient. To compare the efficiency of the revised and the original keypad, computations using Fitts' Law, Hick-Hyman Law and KSPC were done. Results showed that the new keypad layout was more effective than the original keypad. Introducing a improvised keypad to the Filipinos is one step closer in achieving customized services and features to Filipinos in mobile computing.

Although the incidence is not high in the general surgical population, pulmonary aspiration of gastric contents can result in serious long-term morbidity and mortality. We report a case of early use of extracorporeal membrane oxygenation (ECMO) to correct severe hypoxemia refractory to conventional mechanical ventilation in a patient with massive aspiration of gastric contents immediately followed by acute lung injury during general anesthesia induction. A 64-year-old woman diagnosed with stomach cancer was scheduled for elective diagnostic laparoscopy. Although there was no sign of gastrointestinal tract obstruction and midnight Nil per Os (NPO) was performed before the operation, pulmonary aspiration occurred during the induction of anesthesia. Despite the endotracheal intubation with mechanical ventilation, severe hypoxemia with hypercapnea persisted. Medical team agreed with applying veno-venous (VV) ECMO, and her blood gas analysis results became stable. ECMO was weaned successfully 9 days after the first aspiration event had occurred. Based on this case, early application of extracorporeal life support can have survival benefits.

Sarcopenia is an ageing-related disease that results in progressive muscle volume decrease. Stroke is also an ageing-related disease and many stroke patients have underlying sarcopenia in whom functional decline may be more severe than neurological damage; however, in the acute stage of stroke, sarcopenia can be underestimated so the patients may not receive appropriate evaluation and treatment. This report suggests the need for diagnosis using dual-energy X-ray absorptiometry when sarcopenia is suspected in patients with stroke. Furthermore, if sarcopenia is confirmed, it is necessary to provide rehabilitation intervention tailored to the disease because appropriate treatment can promote the return to daily life. After an accurate diagnosis of sarcopenia, a quantitative muscle strength evaluation, an exercise prescription that considers fatigue and appropriate amino acid supplementation are necessary to establish a strategy for rehabilitation intervention.

Witsarut Sriratana,Namo Narknam,Ruangsit Apichitanon,Narin Tammarugwattana 제어로봇시스템학회 2020 제어로봇시스템학회 국제학술대회 논문집 Vol.2020 No.10

This paper presents the image processing system for quality inspection of rice grains after sorting process by using an ordinary webcam to ensure that rice grains should meet the quality standards and impurity such as grits, dirt and stones should not be found [1]. Moreover, statistical information of rice grains from image processing could be taken into analysis to enhance the efficiency of the sorting process. Image data analysis of rice grains can be divided into 2 main arrangement conditions, non-overlapping and overlapping. In this study, the experiments to inspect rice grains were applied for 24 samples and 18 experimental designs including the complete and incomplete structures, the overlapping and non-overlapping arrangements, and the combination of rice grains from complete and incomplete structures in equal and unequal ratios. From experiments, it was found that the inspection of rice grain quality by using image processing technique and image data recorded by an ordinary webcam was reliable and efficient. The inspection errors under non-overlapping arrangement condition of complete and incomplete structures of rice grains were not observed. The inspection errors of rice grains combined from complete and incomplete structures in equal and unequal ratios were about 0.8% and 1.11%, respectively. However, under overlapping arrangement condition, it was observed that the inspection errors of image processing would be high by up to 53.82% on average.

Persistent Left Superior Vena Cava Detected Incidentally after Pulmonary Artery Catheterization

Hyun Jeong Lee,Namo Kim,Hyelin Lee,Jae Kwang Shim,Jong Wook Song 대한중환자의학회 2015 Acute and Critical Care Vol.30 No.1

We present a case of pulmonary artery catheter (PAC) placement through the right internal jugular vein, bridging vein and coronary sinus in a patient with previously unrecognized persistent left superior vena cava (LSVC) and diminutive right superior vena cava. A 61-year-old male patient was scheduled for mitral valve repair for regurgitation. Preoperative transthoracic echocardiography revealed dilated coronary sinus, but no further evaluations were performed. During advancement of the PAC, right ventricular and pulmonary arterial pressure tracing was observed at 50 and 60 cm, respectively. Transesophageal echocardiography ruled out intra-cardiac knotting and revealed the presence of the PAC in the LSVC, entering the right ventricle from the coronary sinus. Diminutive right superior vena cava was observed after sternotomy. The PAC was left in place for 2 days postoperatively without any complications. This case emphasizes that the possibility of LSVC and associated anomalies should always be ruled out in patients with dilated coronary sinus.

Fixed Pupillary Light Reflex due to Peripheral Neuropathy after Liver Transplantation

Kwan Hyung Kim,Namo Kim,Sungwon Na,Jaewon Jang,Jeongmin Kim 대한중환자의학회 2015 Acute and Critical Care Vol.30 No.3

A 46- year-old female patient was admitted to the intensive care unit (ICU) after liver transplantation. About an hour later after the ICU admission, she had no pupillary light reflex. Both pupils were also fixed at 5 mm. Patients who undergo liver transplantation are susceptible to neurologic disorders including hepatic encephalopathy, thromboembolism and intracranial hemorrhage. Abnormal pupillary light reflex usually indicates a serious neurologic emergency in these patients; however, benign neurologic disorders such as peripheral autonomic neuropathy or Holmes-Adie syndrome should also be considered. We experienced a case of fixed pupillary light reflex after liver transplantation diagnosed as peripheral autonomic neuropathy.
