114 untethered UUV dives: lessons learned
The Ocean Engineering Division at the Naval Command Control and Ocean Surveillance Center RDT&E Division (NRaD) has developed and field tested two successive untethered, supervisory controlled UUV systems: a prototype, and an improved model. These robotic vehicle systems were part of the Advanced Unmanned Search System (AUSS) programme. It was only after the prototype was fielded, many lessons were learned. As a consequence of the prototype experience, the improved model was developed. The second system was a complete redesign, using state-of-the-art subsystems and technologies. The resulting product was both capable and reliable, yet flexible, creating a plethora of system evolutionary possibilities. Sea tests, improved tactics, and systems engineering became synergistic and interactive. AUSS involved pioneering research in underwater search and in UUV systems. Important knowledge was also gained in systems analysis, system engineering, and program evolution. Invaluable experience was gained from 114 successful untethered dives. The purpose of this paper is to share many of the lessons learned during the AUSS program.

A LITERATURE REIEW OF TARGET COSTING IN SSCI AND SCI&SCI-EXPANDED INDEXES
Target costing as a cost management and profit planning system is used by many competitive firms since 1970s. Although the concept is simple, the implementation needs an extensive collaboration inside and outside of the organization. In contrast, many organization managers think that target costing is just related with accounting and finance staff. Our study aims to review the literature of this important concept; target costing by examining 41 English articles published in SSCI and SCI&SCI-Expanded between 1985-2008. The study aims to briefly explain the content of each article to show the reader what has accomplished so far.
