Objective: This study aims to suggest different approaches in analyzing risks associated with musculoskeletal disorders (MSDS) for risk assessment. Background: Upon concluding that the changes in the industrial environments have made it hard to regulate diverse risk factors, the government has implemented a policy for risk assessment. Method: This study has proposed a method, creating programs using Excel that perform qualitative or quantitative analysis, for evaluating risk factors in risk assessments and has applied this in manufacture and service industries. Results: To verify the validity of the developed program, risk assessment has been performed on restaurant chefs as an example. For quantitative evaluation, the study has suggested approaches using the results for REBA evaluation and the analysis report on the work scenes of a fitting-shop in a shipbuilding industry. Application: Constructing and adapting a system using Excel in evaluating risk factors for risk assessments as this study suggests, is expected to contribute to revitalizing risk assessments.

The objective of the study is to investigate the influence of aesthetic attributes on user interface design. Theories of aesthetics are first studied from which aesthetic attributes are defined as information sources. Representation of a product is viewed as a combination of aesthetic attributes, based on a hypothesis that each attribute has a certain influence on the performance in terms of user interface. An experiment was conducted to support the hypothesis. Various combinations of aesthetic attributes of a microwave oven were generated from the orthogonal array of a conjoint analysis. Subjects perfomed on a computer two types of tasks, each of which simulated a combination of attributes. Reaction time was evaluated as a performance measure for the conjoint analysis to find out how much influence each attribute has on the performance. A computer program, UISA(User interface Simulation system of Aesthetic attributes0, was developed and used for simulation. Findings on the influences of aesthetic attributes were summarized.

For the medical approaches of work-related musculoskeletal diseases, it is important to consider occupational relatedness and occupational fitness. Clinical approach includes physical examination, radiologic tests and other related tests and we should choose proper management which is suitable to workers' status for the prevention of early disease's progression and later disabilities. Also, it suggests that occupational prevention program consultation for work-related musculoskeletal diseases considering workers' variable circumstances should be done via occupational relatedness and occupational fitness.

The purpose of this study was to investigate the relationships between weights of backpack and back and shoulder pains of elementary school students in Korea. A cross-sectional sample of 278 boys and 233 girls aged between 7 and 12 years were analyzed for this study. 49.1% of the participated children reported their backpacks were felt heavy, and the weights of their backpack were grater than 13.3% of their body weight. About 65.4% of students carried greater than 10% of their body weights. The weight of the backpack showed significant positive relationship with shoulder pain but not with their back pain. The results of this study suggested that overweighed backpack could cause the musculoskeletal pain to the elementary school students. Therefore, an effective backpack safety program for parents and students is necessary to educate them how to prevent possible musculosketal pain related to the weight of backpack within the perspective of the ergonomical approach.

This study is plan to show what kinds of problems we have and how we can overcome problems about occupational safety and health education and training system in Korea, Some features which advanced countries had were found and characterized as follows; First, advanced countries realized the importance of safety and health education on the role of preventing accident and they had varieties of training and education programs on the industrial safety and health for employer and worker. Second, there were many safety and health education programs and grants which especially focused to the small businesses. Third, they had also several programs to induce employer and worker's concerning about the safety and health education voluntarily, In conclusion, we introduced some inducing models, and proposed to revise contents of the education programs and to increase participation of other parties in safety and health education market so that could vitalize our safety and health education and training.

In this study. differences in attention allocation patterns between expert and novIce pilots were investigated by a verbal protocol when pilots were engaged in a task during the instrument flight. Ten pilots including experts and novices were participated to conduct a pre-determined task(a fix-to-fix) on F-5E Cockpit Procedure Trainer Simulator. Experts show better performance as expected with more stable variations in speed. altitude. and attitude. In attention allocation patterns. novices allocated about 83% of attentional resources on the primary instruments (airspeed indicator. altitude indicator. and attitude) relating to the task of the basic flight while experts spent 57%. This difference in the availability of attentional resources allowed expert pilots to accomplish the task better than novices. In other words. training a pilot should consider a program for building up wider instrument scanning patterns to become an expert in a shorter time.

Seat belt is an important means to protect drivers and passengers from the damages by car accidents. Many ways to increase the seat belt wearing rate have been proposed through human factors researches. The primary ways to increase seat belt use rate have emphasized the intention-behavior cycle. This study focused on the gap between intention and behavior. The gap may be bridged by the habit for seat belt use behavior. Divers following a desirable car starting sequence, from sitting on the chair, fastening seat belt, starting engine to moving a car, reported that higher belt wearing rate and unconscious behavior (automated response). That is, the habitualized procedure knowledge prevented drivers from forgetting to fasten their seat belt. The reminder systems such as warning light and warning sound could not significantly give an influence in remembering to fasten seat belt. In order to increase the seat belt use rate, the desirable car starting procedure should be included in the driving education program.

This paper measured the range of arm joint motion for Korean 54 males in twenties. The range of the arm joint motion of the subjects was measured directly using Goniometer and protractor. The number of the static and the dynamic anthropometric variables are seven and thirteen, respectively. The anthropometric data are analyzed by basic statistical analysis (four group), correlation analysis and regression analysis using commercial SAS program. The results of analysis are compared with American students anthropometric data by Laubach(1978). Thin subjects have larger movement angle as wrist flexion, wrist abduction, elbow flexion, and elbow wupination and have smaller as wrist adduction and shoulder flexion. Fat subjects have larger movement angle as shoulder flexion and are smaller wrist abduction, elbow flexion, pronation, shoulder extension, shoulder adduction, shoulder abduction, and shoulder medial rotation Korean are more flexible than American in wrist and ranges of elbow flexion and elbow rotation. The shoulder movement is similar to that of American, but shoulder flexion is less flexible.

A statistical method was developed to examine the US navy women's sizing system. Subjects including 906 navy female personnels were classified into seven groups based on the body type. Regression analyses were performed within seven groups to determine the sizing system maximizing the fitness of clothing in each group. New parameters were developed and used to statistically investigate the fitness level based upon boty navy sizing system and regression based system in this study. A customizef SAS program was used to compute the fitness levels. Results indicated that the navy sizing system showed lower fitness level in most groups except Juniour than the regression based system. It was concluded that the current method with new parameters could be used as an objective tool to evaluate the existing or new sizing system. This method can be further validated in other sample populations.
