A variety of research has been conducted on anthropometric dimensions and their applications to various products and space architecture, Also robust research has been conducted on various parts of human body and the possibility of applications. However, research on the specific dimensions regarding fingers and characteristics of hands have rarely been conducted in Korea. In addition, except for the NASA Anthropometric Source Book that suggests measures for specific purposes such as gloves and hand-operated device, almost no literature can be found on this topic, The primary objective of this study was thus to provide anthropometric dimensions of Korean hands and fingers and recommend appropriate product design solutions for human hands. Six hundred Korean male and female subjects aging from 11 to 93 were selected, Thirteen different hands and fingers were measured along with demographic data(e.g., age, stature, weight} to determine the relationships among these obtained data, The results of this study should be considered in ergonomic design for every hand-used products and hand-operated control devices.

This paper discusses the next direction for user experience design to keep pace with an ongoing IT paradigm shift, particularly focused on UX standardization activity contributing to reinforcement of brand power and customer loyalty. The paper introduces a model that identifies four levels of UX standardization and a key concept called "sustainable UX ecosystem" as its top level. It argues that in the new IT paradigm the fourth level of UX standardization, the sustainable UX ecosystem, is the next direction user experience must head towards.

It is necessary to quantitatively evaluate the workload of workers in order to improve the level of safety and efficiency as well as to prevent workers from musculoskeletal disorders. The purpose of this study is to introduce biomechanical methods that are largely used to quantitatively evaluate workload. The biomechanical methods use kinematics and kinetics to analyze the movement and force of biomechanical body. Motion analysis, joint angle measurement, ground reaction force, mathematical model, and electromyography (EMG) were introduced as a tool or device for biomechanical evaluation. In this study, the special feature of each method was emphasized and important tips for field measurement were summarized. The information and technique disclosed in this summary can be used to evaluate and design the workplace better by effectively control the workload of field workers.

In order to provide the basic data for planning of stairways design in elderly housing, the study of Ergonomics were exmined. 3 old women and 3 female subjects were tested: 1) The relations between blood pressure and pulse: In case of the old, blood pressure was the highest at 13 cm and pulse was the highest at 23 cm. But in case of the young, the former was the highest at 23 cm and the latter was at 13 cm. 2) EMG: According to the height of stairs, the significant differences on the statistics were not seen. 3) Riviewing that biological characters according to the finishing materials, in case of the old groups, they feel most stable, as they up the wooden stairs. While they feel very dangerous, as they up the stairs where carpet is on. In the biological characters according to the stairs heights and the finishing materials, the most stable conditions for the old are 15 cm-high-stairs, wooden. And even if the stairs used inside the house, the installment of the handrails at both side must be considered.

This study is to define a congitive paradigm including a new model of common cause human behavior error domain and to analyze their causal factors and their properties of common cause human error characteristics in software engineering. A laboratory study was performed to analyze the common causes of human behavior domain error in software development and to identify software design factors contributing to the common cause effects in common cause failure redundancy. The results and analytical paradigm developed in this research can be applied to reliabbility improvement and cost reduction in software development for many applications. Results are also expected to provide training guidelines for software engineers and for more effective design of ultra-high reliable software packages.

The objective of this study is to collect and analyze the anthropometric data for Korean adults. These data are intended to be used for the product design in industry. Sixty three college students participated in the measurement. One hundred twenty four lengths, thirty circumferences, four strengths, weight, and age data were collected. Descriptions and statistical analysis of the anthropo- metric data are summarized. The results were compared with foreign data available. It was found that forty weven body dimensions were closely correlated each other. It was also found that three dimensions, stature, eye height, and hand length, can be assessed by adding other body dimensions.

Today, rapid development and timeliness of introducing a new product be- comes a more influencing factor of determing its competitive power due to a shortened product cycle, while rapid improvement of manufacturing technology makes product design and manufacturing fuse together. This implies that prod- uct usability evaluation and improvement starts right from its design phase, resulting in less development time and cost. To make this possible, proper as- sessment of human reach is one of essential functions for ergonomic product us- ability evaluation, specifically in the platform of computer-aided ergonomic evaluation models or any CAD system with a built-in man model. In this study, an analytic reach prediction algorithm ensuring the posture that human naturally takes, is presented by employing the methods developed for robot kinematics. Among robot kinematic methods for solving the multi-link system, the resolved motion method was found to be effective to solve human reach as a redundant manipulator model. Also, the joint range availability was used as a performance fonction to guarantee human naturalness. The result is expected to be directly applicable to product usability evaluations.

Most designers of equipment, or of a workplace layout, frequently choose 5 percentile female and 95 percentile male dimensions as design limits. If the design is not an one-dimensional problem, it is difficult to choose '5 percentile female' or '95 percentile male'. Hence it is important to consider the interactions or relationships between body dimensions. This paper deals with correlation analysis, factor analysis and partial correlation analysis using data above age 20 from the national anthropometric survey in Korea, 1986. Besides, a model which represent the extremes of body size of Korean has been developed in this paper.

The purpose of this study is to identify the types and features of job rotation being operated in a motor company. The types of job rotation have been classified according to the range of rotation and its cycle. Also, the features of the favorable rotation types were examined by the worker's age and their types of tasks. The results show that workers prefer broader ranges and slower cycles of rotations as they age. Moreover, older workers tend to show an increase in the preference of participating in job rotations. The result of this study is expected to be applied as fundamental data to job design.

Macro interface is primarily focused at the organization, while micro interface is primarily focused at the products or services. UI(User Interface) or UX(User Experience) organizations in Korea are institutionalized from 2000 years. Since most of the UI organizations are not institutionalized with the strategic plan, structures of them aren't optimized efficiency. The structure of the organization is conceptualized as having three core dimensions: complexity, formalization, and centralization. The status of the UI organizations in Korea is reviewed with these dimensions. This study issued the key success factors for institutionalization for UI team. Organizational maturity is considered in 5 levels based on a model by CMMI. The UI strategy has to be based the maturity level of the organization.
