Application of EKIDES¡]Ergonomic Knowledge Intelligent DEsign System¡^to training and ergonomic evaluation of the instrument panel in nuclear power plant

Lin, Tien-chi 07 September 2007 (has links)
The public security and working safety are the most important issue for technical engineers operated in nuclear power plant, to face the works with the equipment in nuclear power plant. An Ergonomics Knowledge and Intelligent DEsign System¡]EKIDES¡^ was developed by Munich University of Technology, Germany. EKIDES is a set of ergonomic project software, which has been applied to some institution, such as BMW, AUDI and RWE Essen. This thesis is mainly based on EKIDES, which is introduced to the ergonomic training as well as aids for staffs survey the operation of nuclear power plant. First, EKIDES has been translated to a Chinese version, which includes the existing task analysis, such as environmental factors, technical components, service manual and operating instructions, referring the data of body size, forces and motions, for the most basic requirement of ergonomics. Second, the customer information about the nuclear energy is added into the database, including basic rules and laws of nuclear power plant. Third, a remote function is linked into EKIDES. By utilizing a web-cam, one can have the convenience for monitoring security and a training for operating nuclear power plant. Finally, an assessment interface is developed by Visual Basic for testing the comfortableness of the panel color of instrument. From this program one has a questionnaire test for comfortable color. Through analysis, a distribution of comfortable color has been found out referring to the panel design for the future. This work can also be used for training new employees of nuclear power plant. This study has performed for testing some engineers in the Third Nuclear Power Plant of Taipower Co. in PingTung, Taiwan. A comfortable panel color and brightness distribution has been analyzed from color scale of red, orange, yellow, green, blue, indigo, purple, black and white. In accordance with the result, the comfortable color of background is in the range of blue, indigo and green, and the comfortable brightness of background is between 14 to 20 Lux.

Diversity in Perception of Alternatives as Related to Selected Aptitude and Background Factors

Lott, Jane Agaya 01 May 1968 (has links)
The relationship between breadth of perspective, defined as the range of alternative solutions that one is able to bring to mind whn presented with a problem, and selected aptitude and background factors was studied. Scholastic aptitude was the chosen aptitude factor. The background fac tors chosen were: (1) size of home town; (2) number of towns lived in; (3) number of children in the family of origin; (4) the subject ' s perception of his travel experience; (5) number of books read during the past year; and (6) number of friends of other nationalities. The sample consisted of 130 female students from five selected classes in the College of Family Life at Utah State University during the 1967 - 68 school year The instruments used were: (l) a background questionnaire; (2) scholastic aptitude, as measured by the students' ACT scores; and (3) Warshay's three unfamiliar problem situations . The statistical t es t used was the Independent x2 t es t of significance. No significant relationship was found between the number of alterna tives perceived and scholastic aptitude, size of home town, number of towns lived in, number of children in the family of origin, or number of books read during the past year. Perception of alternatives was related to the subject's perception of his travel experience at the .05 level and to number of friends of other nationalities at the .10 level .
