Objective: The aim of this paper is to introduce ergonomic evaluation methods for agricultural work. Background: Work-related Musculoskeletal Disorders(WMSDs) became a major problem in agriculture industry recently. A number of ergonomics evaluation methods have been developed in order to evaluate the work load for preventing WMSDs. The workload evaluation methods were developed for manufacturing industry. Therefore, these ergonomic evaluation methods were used carefully in agriculture industry because work type in agriculture different from work type in manufacturing. Method: Various references of ergonomic evaluation methods such as OWAS, REBA, RULA, NLE and Snook table have been reviewed for agricultural work. Results: This paper presents the characteristics, the selection and application procedure of ergonomic evaluation methods for agricultural work. Application: These results can be used to provide baseline information for ergonomic evaluation methods.

The purpose of the paper is to review current trends and future issues of automotive ergonomics. The current trends include 1) universal design considering for regional differences, elderly drivers, female drivers, 2) quantification of driver's discomfort 3) trade-off between design trends and comfort, 4) digital ergonomic evaluation with digital human models 5) optimization of driver's interface. The future issues of automotive ergonomics cover 1) intelligent driver assistance system 2) Fun-to-drive and 3) differentiation from other vehicles based on ergonomics.

Ergonomic ship design aims to improve the safety and convenience of crew and passenger. Recently, ergonomic design is a key issue in the warship design, as a basis of analysing and evaluating ergonomic design and evaluation methods for warship, existing military design guidelines and navy criteria in the fields of ergonomics were surveyed. Also, the methodology including ergonomic human model was introduced. Finally, it is shown that the ergonomics evaluation of a design at the early stage of warship design can be performed using commercial ergonomics evaluation model such as Delmia's ERGO.

'Emotional value' has been a buzz word for design and ergonomics in the era of business innovation. However, the complication of 'emotion' in terms of literal and practical meaning has made it a challenging but confusing task for designers to develop a new product with emotional value. 'Sensibility' and 'emotion' are interchangeable terms to describe human feeling ('gamsung' in Korean). The confusion reached at its peak with Korean terms. Even scholars in Korean language, psychologists, ergonomists, and designers are bewildered at the choice of proper expression for human feeling in both Korean and English. The difficulty could explain the problems in 'sensibility ergonomics' in Korea. The purpose of this paper is to provide both fundamental and satisfying information with people in the area of 'sensibility ergonomics'. Therefore, in this paper, a number of articles and books on sensibility, psychology, sensibility ergonomics, and design were reviewed to clarify the meaning of sensibility and relationship among similar words that have been used with unintentional misunderstanding. Also many adjectives on human sensibility were collected and complied for the use of sensibility evaluation.

As the method of providing information is getting multimedia, the synthetic voice is used in not only CTI(Computer Telephony Integration), information service for the blind, but also applications on internet. But properties of synthetic voice, such as speech rate, pitch, timbre and so on, are not adjusted to customers' preference but providers' preference. In order to consider customers' preference, this study proposed four subjective factors of voice through the evaluation of voice using the method of sensibility ergonomics. And the relation synthetic voice to be agreeable to the ear with emotional images was formulated as a fuzzy model. Consequently, this study proposed the speech rate and pitch of synthetic voice which is agreeable to the ear.

Virtual reality can be applied well to product design and evaluation. A virtual design evaluation system for an automobile cabin was implemented on a desk-top virtual environment system. It has two frontal seats, a dashboard, a steering wheel, and various displays/controllers. Users can interact with these components as they do that with real ones. To verify the effectiveness of the virtual design evaluation system, 17 subjects participated in the evaluation procedure. The evaluation result showed that the stereoscopic vision enhanced the subjective reality of the virtual automobile cabin. Graphic details, design, and time lag were also related to the subjective feel for reality.

Data obtained for sensory evaluation have a wide dispersion and fuzziness since human sensory organs are used as a means of measuring sensation instead of measuring instruments. Such dispersion and fuzziness are caused by all kinds of time error and have a great influence on the sensory evaluation, but most of previous papers not consider time errors. In this study, the comparative judgement capability of the evaluator was discriminated by means of the eigen- structure analysis on the premise that evaluation values of sensory evaluators obtained by a paired-comparison become different by the order of sample presentation.

The evaluation of product may be classified by technical tests or by ergonomics assessments. If an ergonomics assessment is required, then the three types of interface dimension are available to the researcher. In this paper, we proposed the heuristic evaluation method for usability of product in the three types of interface dimension The evaluation method is used the fuzzy weighted checklist technique computerized for evaluating or comparing prototype of system and IT product.

The objective of this paper is to study the usability of the ingress/egress of elderly people, and analyze the physiological workload electromyography (EMG). We investigated the factors of discomfort while the elderly people are using the ingress/egress. Experiments were performed using a seating buck with 22 elderly participants (over 65 years old). The results showed that different muscles are activated during ingress and egress. A system called "easy access" was found which helps to access easily when a driver gets into a car. The current easy access was compared a newly proposed one. It was found that elderly people use less muscle during in/egress in the new easy access system.

Evaluation of user interfaces has to be performed in an intuitive and subjective manner by experts especially when the problem comes to the complexity and consistency of sophisticated interface procedures. The manual analysis and evaluation of logical interfaces also tends to be slow and laborious. To make the evaluation more formal and objective, the criteria and the procedure with which the evaluation can proceed must be explicitly prescribed. Furthermore, to make the formal procedure as practical as subjective expert evaluation, the criteria must reflect the user knowledge of the target tasks since the task knowledge plays the role of a basis for users to understand the interface organizations and procedures. This paper describes ESTIM, a support system for task-based evaluation of user interface, that includes the interface evaluation criteria and implies an evaluation procedure. The support system can be used either in an interactive manner by the analyst during the evaluation or in an automatic evaluation mode. It was verified that the result of automatic evaluation by ESTIM matched the results of expert evaluation fairly well.
