AN all‐magnesium aircraft has been built in the United States by East Coast Aeronautics Inc. under contract to the Air Force Air Development Center. It is the latest in a series of projects connected with the use of magnesium for aircraft primary structures. J. P. Donald Garges, vice‐president of the company, gave a detailed account of these projects in a paper presented to the Institute of Aeronautical Sciences at its annual meeting in January 1955, and published in Aeronautical Engineering Review in August 1955.

HOLLOW steel airscrew‐blades which, it is claimed, are stronger, weigh no more, and are less susceptible to impact and abrasion than forged aluminium blades of the same size are being manufactured in quantity from seamless steel tubing by the American Propeller Corporation, a subsidiary of the Aviation Corporation. The conception of using tubing for blade making is logical, but the difficulties of putting it into practice were great and required the development of many new methods and production tools. For the following description and accompanying illustrations, the author is indebted to the Propeller Corporation and to supplemental information contained in an article in Steel written by A. H. Allen, Detroit editor of that journal.

Dr. D. G. Hopkins, a joint managing director of I.C.I. Paints Division, has retired after 33 years of service with I.C.I.

ALL essential data on operation, performance and stresses of a new‐model aircraft in flight test are picked up, transmitted and recorded automatically by a radio system developed and built by Vultec Aircraft Inc., of Downey, California. The indications of seventy‐two different instruments in the machine can be transmitted a distance of about 100 miles and recorded simultaneously at a ground station at a maximum speed of 100 instrument readings per second.

TIME spent and expense incurred in making jigs, fixtures and some other production tools have been reduced substantially during a tooling simplification programme conducted for more than five years by the Republic Aviation Corporation, of Farmingdale, NY, USA.

FIRST doubling, then tripling of the rate of production of the Lockheed Lightning fighter without expansion of plant size has been made possible, by ingenious engineering adaptation of automobile chain‐line assembly practice to aircraft manufacture. The accompanying illustrations show clearly some of the features of this system.

AIRCRAFT production engineers have long sought detailed information regarding the laminated wood construction process which has been under development for a number of years by the Duramold division of the Fairchild Engine and Airplane Corp. for production of the company's AT‐21 advanced trainer and PT‐19 Army patrol‐torpedo planes. This information has been made generally available, however, only since the end of 1943, after success of the development had been proved not only experimentally but in production operations of considerable volume.

Accounting Education Change Commission reveals that accounting professionals are required to have interpersonal skills. For this reason, higher education requires the dynamics of learning that can foster critical thinking skills, analysis, communication, negotiation, cooperation and argumentation. Therefore, studies in the field of accounting education have led to a project approach to provide students with complex learning experiences to develop various supporting skills in addition to learning outcomes. Interestingly, the methods have its own dilemma with social loafing in groups. Therefore, a lecturer must be able to match it with an appropriate evaluation instrument. The purpose of this paper is to examine the effect of implementing peer evaluations and project-based learning (SMEs project) on improving the interpersonal skills of accounting students.

The population of this research is Accounting students at Medan State University, while the sample is students who are undergoing Cost Accounting courses taken with purposive sampling. The within-sample of field experiment method was conducted in the current study. Furthermore, data analysis was performed using one-way ANOVA analysis assisted by SPSS 19.

The results of this study showed that students had an increase in interpersonal skills in their board, and peer-evaluation design resulted in learning satisfaction and fairness in students.

The results of this study produce practical recommendations for lecturers to innovate their learning activities with actual project design and control group dynamics with accommodative evaluation designs. This study provides new insights in building a comprehensive instructional design, so it can strengthen the concept of instructional and evaluation designs which are integral parts that should match between one another.

ENGINEERING of the Airocobra fighter proceeded from the conviction of the Bell Aircraft Co., of Buffalo, N.Y., at the time of its organization in 1935, that a superior interceptor must combine the highest attainable speed with utmost destructive fire power, and therefore would have to be different from any then produced by‐established aircraft companies in the United States.
