Proper ergonomic design of a passenger seat for the highspeed train is one of the essential design components that is directly related to passenger comfort. This study investigated a systematic approach to the ergonomic passenger seat design and evaluation for the Korean highspeed train. To design an ergonomic passenger seat that improves passenger confort, Korean anthropometric data, pas- senger activities in the coach, body postures, body contours and seat dimensions were considered. By analyzing the interredlationship of such factors, resultant seat dimensions were suggested. To properly ecaluate the suggested dimensions, four prototypes were subsequently made and iteratively tested in the laboratory. It is expected that this approach is readily applicable to the passenger seat design of other transport vehicles as well as a train.

According to several pilot tests, petite women have their own body proportion which is not simply an overall diminutive reflection of the proportion of Misses sizes. Apparel manufacturers and pattern companies do not consider racial differences nor do they consider petite women's own specific body proportions in their size categories to produce petite garments. The primary objectives of this study was to describe the petite women's body proportions especially the differences between Asian and Caucasian petite women and to compare their body proportions to the average body figure. A physical body measurement chart was developed and revised through a pretest. Sixty subjects, thirty for each group of Asian and Caucasian. They were landmarked using an anthropometric instrument and photographed using the method of somatography for analysis of body proportions. Data were analyzed by t-test for a description of the petite subject's body proportion. The results of this study indicated that the Caucasian subjects had generally a longer lower torso than tehAian subjects in their body proportions. both subject groups had differnt body proportions from the aerage body figure.

A local manufacturing companyin which low back pain(LBP) complaints were frequently reported was selected, and regularly perfomed lifting tasks were investigated using questionnaires and the 1991 NIOSH lifting guide. Among several processes of manufacture in the company, three processes-forming, heating and packing-were studied, where most of tasks were perfomed through manual materials handling (MMH). Questionnaire surveys showed that anthropometric data such as stature, weight and someatotype did not affect and weight of load influenced significantly the incidence of LBP, and workers who expwrienced LBP was older than the inexperienced. In addition, safety education conducted at the company was found to be ineffective in preventing LBP injuries. Lifting indexes(LI) was ranged from 0.86 to 17.0 with an average of 4.49, which revealed that tasks performing in the selected factory were in danger of LBP, and should be ertonomically redesigned. The critical factor reducing LI was found to be the horizontal component in all three processes, and most of weight of load was heavier than load constant(23kg) of the 1991 NIOSH lifting equation in heating process and packing.

Human dummies are essential tools in the development of such products as vehicle have been actively used not only in reach and view field tests. but also in impact perception evaluations. This study attempted to obtain geometric and dynamic model body segments from Korean anthropometric data. The investigation focused on the de both human and dummy for the geometric and inertial properties. The dynamic modeli being suggested is based on rigid body dynamics using fifteen individual body segments by joins. The segments are connected at the locations representing the physical joint body so that each segment has its mass and moment of inertia. For visual three-dimensional graphic was used for easier implementation of the dumn applications. For applications, proposed Korean dummies Were used in dynamic crash and driver's view and reach test modules were developed in virtual environment.

This study was designed to investigate the effects of work postures and anthropometry on the musculoskeletal discomfort of the telephone operators involved in VDT tasks. The level of musculoskeletal discomfort were evaluated for 279 VDT operators from three different workplaces. The work postures and the anthropometric data were evaluated for 70 VDT operators out of the total of 279 operators. Multiple regression analysis was utilized to examine the relation- ship between the measured ergonomic variables and the level of the musculoskeletal discomfort. It is evident from the result of the study that the ergonomic factors have great influences on the level of the musculoskeletal discomfort.

This study is focused on the development of a child human model, which is composed of skin, skeleton, joints and muscle, etc. The dimension of child outer skin is referred to anthropometric data from KRISS (Korea Research Institute of Standards and Science). The positions of joint and mass properties of body segments are calculated from ATB(Articulated Total Body) program, GEBOD. The properties of bones and muscles are obtained by the way of scaling from adult human model. To verify the developed human model, ROM simulation and sled test is conducted. Developed human model can be effectively applied to the evaluation of human injury in crash situation and development of child restraint system. The explicit finite element program $PAM-CRASH^TM$ was used to simulate six-year old child human model.

A nutrition survey of 133 children, 9 to 12 years old, in the Nan Hyang elementary school, which offers no school lunch program and is situated in Shinllim 7-dong of Seoul, as the location of one of the socioeconomically vulnerable groups, was undertaken in July of 1989, to investigate dietary intake. Total daily energy and nutrient intake were below the RDA's, except for intake of vitamin. A and ascorbic acid. Carbohydrate provided 69% of total energy intake ; protein accounted for 12% ; fat provided 19%. The survey found that 15% of subjects skipped a meal more than once a day. Nutrient intakes of boxed lunch prepared at home and school, lunch eaten at home were out of balance. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the urgent need for expansion of the school lunch program.

Human Factors Engineering (HFE) for Main Control Room (MCR) of Nuclear Power Plant (NPP) has been applied to optimize the design and operation of Man-Machine Interface (MMI) between operators and their equipment in consideration of physical, psychological and cognitive aspects. However, it has been observed that operators complain about environmental discomfort in the MCR since the operators in the MCR experience excessive stress due to the environmental factors such as inappropriate interior and lighting system. Since the HFE is an essential factor for the high fidelity performance of operators in the MCR, the adequate MCR environment design with HFE rules and guidelines is as much important to enhance the operability and reliability of the MCRs. Therefore, there has been a strong need to design a pleasant environment for the MCR to improve human performance of the operators.

A parametric body model generation system has been developed. Using various mathematic and geometric algorithms of this system, a three-dimensionally scanned human body can be converted into a resizable body model. Once a parametric body model is formed, its size and shape can be modified instantaneously by providing appropriate anthropometric data. To facilitate the subsequent pattern arrangement process for garment drape simulation, a bounding box generation algorithm has been developed in this study. Also the model can be converted into a set of parametric surfaces that it can also be used for three-dimensional garment pattern design system.

The purpose of this study was to establish the range of the body frame size determination for elderly subjects. Anthropometric data were collected from over 60 years old 229 elderly peoples. Three methods for determining frame size were to measure elbow breadth, ankle breadth, and height to wrist circumference ratio. Among the three variables, ankle breadth exhibited the lowest correlation with skinfold thickness and changed little with age. A pairwise comparision among three methods for determining frame size showed that the highest incidence of overall agreement was achieved when the ankle breadth and elbow breadth were compared. This analysis supported that ankle breadth can be used as an indicator of frame size. Small, medium and large categories of ankle breadth were presented depending on whether the measurements were below the 15th, between the 15th and 85th, and above the 85th percentile for ankle breadth.
