Notch ratio in pulmonary flow predicts long-term survival after pulmonary endarterectomy for chronic thromboembolic pulmonary hypertension.

Background: Assessment of the pattern of the RV outflow tract Doppler provides insights into the hemodynamics of chronic thromboembolic pulmonary hypertension (CTEPH). We studied whether pre-operative assessment of timing of the pulmonary flow systolic notch by Doppler echocardiography is associated with long-term survival after pulmonary endarterectomy (PEA) for CTEPH.

Methods: Fifty-nine out of 61 consecutive CETPH patients (mean age 53 ± 14 years, 34% male) whom underwent PEA between June 2002 and June 2005 were studied.

Technology for reducing distracted driving in developing countries: the level of usage and intention to use in Indonesia.

Distracted driving is a major cause of car crashes. Considering the dangers of distracted driving, efforts to develop prevention and/or reduction technology are underway. The purpose of this study is to observe the level of usage of distracted-driving-reduction technology in Indonesia and model the intention to use this technology on the technology acceptance model (TAM).

The Role of Safety Silence Motives to Safety Communication and Safety Participation in Different Sectors of Small and Medium Enterprises: Investigation Results on Two Kinds of Industries in Indonesia.

Background: A number of accidents have occurred in small and medium enterprises (SMEs). Efforts in reducing accidents have been undertaken through the implementation of safety behaviors. Unfortunately, few studies have examined motives behind unsafe behaviors, such as safety silence motives.

Mobile phone use among Indonesian motorcyclists: prevalence and influencing factors.

Objective: Indonesia is one of many developing countries that relies on motorcycles as a major mode of transportation. Unfortunately, the widespread use of motorcycles in Indonesia coincides with a high number of motorcycle accidents which can often be attributed to unsafe behaviors of the motorcyclist. One unsafe behavior that is common and hypothetically associated with accidents is the use of a mobile phone while motorcycling.

The ergonomics of mothering and child care activities (ErgoMOMics) in Indonesia: Individual and social factors influencing musculoskeletal symptoms.

Background: Mothering and caring for children have been associated with a decrease in mothers' wellbeing. Limited research has been conducted from the ergonomics perspective of mothering and caring for children due to the belief that being a mother is not considered an occupation.

Objective: To observe the ergonomics of mothering and caring for children (ergoMOMics) among Indonesian mothers and the prevalence of related musculoskeletal symptoms (MSS).
