Usefulness of transthoracic lung ultrasound for the diagnosis of mild pneumothorax.

The aim of the present study was to investigate the diagnostic accuracy of ultrasonography in the detection of mild pneumothorax using computed tomography (CT) in dogs. Nine adult healthy beagles were included in the study. A thoracic tube was inserted into pleural space at the left thoracic wall, and each dog underwent the examinations in the order of CT, lung ultrasonography, and radiography before the infusion of room air into the pleural space.

Behavior of PAHs from sewage sludge incinerators in Korea.

Although production of sewage sludge increases every year, its proper treatment has only been recently raised as a new issue, as current landfill and ocean dumping arrangements are expected to become increasingly difficult to manage in the future. The Korean Ministry of Environment plans to diversify its processing facilities and expand its processing systems by 2011, with the purpose of processing all sludge produced in Korea. According to this plan, incineration (including incineration of municipal wastes) will process 30% of the entire sewage sludge throughout the country in 2011.

Predicting unit performance by assessing transformational and transactional leadership.

How do leadership ratings collected from units operating under stable conditions predict subsequent performance of those units operating under high stress and uncertainty? To examine this question, the authors calculated the predictive relationships for the transformational and transactional leadership of 72 light infantry rifle platoon leaders for ratings of unit potency, cohesion, and performance for U.S. Army platoons participating in combat simulation exercises.

Adaptive self-regulation: meeting others' expectations of leadership and performance.

Work-group characteristics and performance in collectivistic and individualistic cultures.

The authors conducted a cross-cultural longitudinal investigation of the effects of culture (individualism-collectivism dichotomy) on group characteristics (functional heterogeneity, preference for teamwork, group potency, outcome expectation) and on performance of 83 work groups performing 2 decision-making tasks over a 15-week period. The individualists (U.S.
