AbstractPhotoelectrochemical (PEC) hydrogen production, using sunlight to split water, is an important enabling technology for a future “Green” economy which will rely, in part, on hydrogen as an energy currency. The traditional semiconductor-based PEC material systems studied to date, however, have been unable to meet all the performance, durability and cost requirements for practical hydrogen production. Technology-enabling breakthroughs are needed in the development of new, advanced materials systems, and toward this end, the U.S. Department of Energy’s Working Group on PEC Hydrogen Production is bringing together experts in analysis, theory, synthesis and characterization from the academic, industry and national-laboratory research sectors. Key Working Group activities, as described in this paper, include performing techno-economic analyses of large-scale PEC production systems and establishing standardized testing and screening protocols for candidate PEC materials systems. In addition, a number of Working Group “Task Forces” are focused on advancing critical PEC materials theory, synthesis and characterization capabilities for application in the research and development of broad-ranging materials systems of promise, including complex metal-oxide and -nitride compounds, amorphous silicon alloys, III-V semiconductors and the copper chalcopyrites. The current status of Working Group activities and progress is summarized.

The phenomenon in the field illustrates that the existence of the working group or forum has not yet provided a significant contribution to the improvement of teacher competency. Various obstacles faced by teachers, principals, and supervisors currently in an effort to create active and effective activity groups. The purpose of this study is to describe efforts to improve teacher competency in developing learning implementation plans through empowering teacher working group activities. This type of research is the principal's action research. The data analysis technique was analyzed descriptively using the percentage formula. Based on the results of the study it was found that: 1) To improve competence in the learning process carried out through empowering competency activities in the learning process carried out through empowering teacher working group activities on a regular basis as much as 2 cycles, each cycle of 2 meetings, each meeting to make four stages of the planning activities, the implementation of actions, observations and reflections. 2) Observation is carried out by the principal as a collaborator supervisor, ending with reflection to see the positive and negative aspects as a basis for planning the next action in cycle 2. With clinical supervision, there is an increase in teacher competence at the beginning of activities 71.43% to 93.73% an increase of 22.30%.

One of the major activities of AGARD Panels is to form working groups which assemble experts who work on the particular subject for two or three years. As a result of the work an Advisory Report is published which compiles the state of the art knowledge on the chosen specific topic. This paper explains the philosophy and procedures adopted during the formation of working groups of the Propulsion and Energetics Panel. Working groups concerning gas turbine technologies are presented. The selected working groups aim to improve the computational and experimental knowledge which would lead to the design of advanced aero gas turbine engines. Objective, scope, procedure, and important results of each Working Group will be explained. Working groups which were active during 1980’s and which are presently active are covered.
