The anthropometric characteristics of the intended user population are most important parameters in the equipment and workplace layout design, particularly in the airplane cockpit design. Because human body is composed of multi-dimensional body segments, single 'average' or 'extreme' manikin is not sufficient in computer-aided design(CAD) environments. To overcome this limitation, we constructed a manikin group representing Korean Male pilot population. First, we identified 16 anthropometric variables which are important parameters in the evaluation of reach, visibility, and clearance. And we found their correlations and conducted a factor analysis. Four common factors were extracted in the factor analysis. The first one was related with length dimensions, the second was with the arm reach, the third was with the sitting height, and the last was with breadth-depth dimensions. Finally, 17 manikins were constructed and presented in the CAD prototype.

Objective: The present study suggested practical measures for successful patent registration based on a review of success and failure cases of patent application filed based on inventions obtained from physical ergonomics research. Background: The protection of intellectual property (IP) contributes to economic growth and competitiveness and facilitates innovation and creativity. IP rights are pursued on research findings for effective technology transfer and commercialization; however, a patent application can be rejected if patentability requirements such as patent eligible subject matter, utility for industrial application, novelty, or non-obviousness are not satisfied. Method: Three successful and three failed cases of patent applications based on physical ergonomics research were reviewed, critical reasons for their successes and failures were examined, and measures were proposed to avoid failures in patent registration. Results: The following measures were identified based on the patent application case review. First, abstract ideas including logical procedures and/or mathematical formulas need to include use of tangible apparatus and methods in idea realization. Second, the provision of grace period inventor disclosure exception needs to be properly followed in case an invention is disclosed before filing of patent application. Lastly, a comprehensive analysis of prior art published or publicly known anywhere in the world and a claim preparation of distinguished, non-trivial features compared to prior art solutions are needed to avoid possible violation of novelty and non-obviousness. Application: The proposed measures can help to prepare a patent application with patent eligibility.

감성 공학 과제가 진행되면서 많은 데이터들이 생산되었다. 하지만 데이터의 효율적인 관리가 이루어지지 않고 있는 실정이다. 이에 효과적인 데이터 관리 및 정보 공유, 나아가 다른 연구에의 활용을 목표로 본 연구를 진행하게 되었다. 연구의 큰 틀은 웹 페이지에서 받아들인 데이터를 바로 데이터베이스에 입력·저장하는 것이다. 이로 인해 크게 웹 페이지와 페이지에서 입렵된 데이터를 받아서 저장하는 데이터베이스, 두 부분으로 구분하여 진행하였다. 본 논문은 데이터 관리의 하나의 예시를 제시하고자 한다.

Classification of Korean characters(alphabets) and frequency data of them are studied that is essential to information process of Korean. We defined a classification of characters using the concept of 'set of 2 parts' and 'set of 3 parts', and we researched frequencies about all combinations of continual two characters. These data would be important basic data to design input device of computer, for example.

Objective: to improve agricultural working environment using tools and equipments. Background: most existing tools currently used, in fact, are discrepant from human factor guidelines so that they are still exposed to the musculoskeletal disease. Method: the provided tools and equipments are mostly designed considering human factor engineering or usability engineering in a way to avoid musculoskeletal disease. Results: propose the top-down procedure and usability engineering steps to evaluate them for the system design suitability. Conclusion: apply them conveniently into rural environment to help farmers working environment.

The purpose of this study is to provide basic information for elderly women's clothing design and to develop dress forms that can reflect the characteristics of their bodies. Three hundered twenty subjects, between the ages of 60 .approx. 85, were chosen and the data were collected from anthropometric data. Principal component analysis which is one of the basic methods in factor analysis was applied to the interpretation of anthropometric data. As a result of analysis, the data are able to be decided into appropriate group.

Anthropometric characteristics and considerations of sex differences are essential for the correct design of ergonomic work spaces. This paper is concerned with longitudinal study on the physical growth in the Korean youth. Five hundred and fourty subjects were selected from third year students of high schools, and their records on physical examination during the last twelve years were surveyed by longitudinal method. This study investigated the anthropometric characteristics of physical structure and the shape of physical growth for boys and girls. The result showed that there were significant sex differences in the pattern of physical growth in height.

Traditional methodologies for ergonomic evaluation are too laborious to be accepted broadly. CAD flex- flexibility and its ease can be a key to breaking this barrier. In this paper, a biokinematic modelis suggested for interactive computer aided ergonomic evaluation. Model parameters are derived and validated by regression analysis. This model showes more flexibility than the stick and joint models. An application is presented to show the clarity of this approach.

The object of this research is to develop an interactive computerized graphic program for graphic output of velocity, acceleration and motion range of body task reference point. Human motions can be reproduced by scanning (rate = 1/60) the vidicon image, at same time, C.O.G of body segment group, and the results are stored in an Apple II P.C. memory. The results of this study can he exteneded to simulation and reproduction of human motions for optimal task design.

우리 주변에는 필요에 따라 많은 종류의 의자를 사용하고 있으며 그 용도와 크기, 모양에 따라 많은 의자가 존재한다. 이같이 수없이 많이 존재하는 의자를 몇 개의 부류로 구분하기란 참으로 어렵고 힘든일이다. 그러나 그 모양이나 형태는 다르지만 그 용도와 기능에 따라 분류 하면 몇 개의 부류로 분류할 수 있다. 이 같은 분류방법은 그 분류기준이 어떻게 정의 되느냐 에 따라 달라지며 그에 따라 의자의 종류가 결정되게 된다. 예를 들면 Shackel은 의자의 종류를 사용되는 상항에 따라 3가지로 분류하였다. 즉 3시간 이상 앉아있게 될때 사용하는 일반적인 의 자, 사무실용 의자와 식탁용 의자로 분류하였다.
