근래 우리나라 농촌지역이 안고 있는 문제점은 여러 가지가 있겠지만, 고령화에 따른 안전사고와 근골격계 질환 환자의 증가가 주목을 받고 있다. 농촌지역의 고령화 현상을 조사한 보고에 따르면 농촌지역은 이미 2007년도에 고령자 비율이 22.2% 넘어서 초고령 사회로 진입한 것으로 나타나고 령화 현상으로 인한 여러 문제들의 대책 마련이 도시지역보다 더욱 시급함을 알 수 있다. 그러므로 본 연구에서는 노화에 따른 신체적, 인지적, 감각적 기능의 변화와 관련된 선행 연구들 중에서 장비의 설계와 평가에 필요한 요소를 추출하고 이를 바탕으로 고령자를 위한 농작업 편이장비의 주요 UI 구조부를 도출하였다.

손목 비틈 작업시 한국 여성들의 연령대별 토크에 관한 연구

손병창,신승헌 대한인간공학회 2002 大韓人間工學會誌 Vol.21 No.4

The present study investigates the maximum and preferred torques of Korean women in wrist operations. A total of 227 women in 20s to 80s participated in the study. The maximum and preferred torques were measured for the combinations of three grip diameters(28, 40, and 66mm) and two twisting directions(clockwise and counterclockwise). The women in 30s showed significantly higher maximum torques; a rapid decline was observed in maximum torque for the women aged 70 years or older. Grip diameter and twisting direction had a large effect on torque production. No significant difference was observed in the preferred torque among the women in 20s to 60s. The ratio of the maximum to preferred torques was not significantly different among the participants in different age groups. Compared to the maximum torque, the preferred torque was 65% for the counterclockwise direction and 68% for the clockwise direction. Standardized regression analysis indicated that the twisting torque was mainly determined by grip diameter, maximum grip force, and age in descending order.

The effectivenes of the opener has also been evaluated. The developed opener increased the torque capability of the wrist by 3.2 times so that most of the elderly can open screw caps. In this study the range of the screw cap sizes tested were between 22.0~ 32.0m, which covers over 92.0% of the screw caps in the market that are difficult to open. This particular screw cap opener developed in this study applies to the aged asstrength.

손목 비틈 작업의 토크에 관한 연구

손병창,신승헌 대한인간공학회 2002 대한인간공학회 학술대회논문집 Vol.- No.-

This study investigates the maximum torque and preferred torque of Korean women in wrist twisting operations. A total of 227 women in their 20"s to their 80"s participated in this study. The maximum torque and preferred torque was measured in three types(A: 28㎜ dia. B: 40㎜ dia., C: 66㎜ dia.), and in the clockwise & counter clockwise directions. The result indicated that the women in their 30"s had the highest maximum torque and had a tendency to decline afterwards. A rapid decline could be observed for subjects after 70 years of age. The shape of their gripping hand or direction of twisting had a large effect on their performance(p<0.001). Between the ages of 20-60 the difference of the preferred torque had no significance(p>0.05) but between the 70-80"s year range a difference could be observed(p<0.05). However, the ratio of maximum torque over preferred torque remained similar over all age ranges. It turned out to be 65.0% for the counter clockwise direction and 68.0% for the clockwise direction. The factors affecting the torque in descending order were the shape of the gripping hand, gripping pressure, and finally the age.

스포츠 유틸리티 차량의 테일게이트 개폐 불편도와 만족도 평가

The difficulties in opening and closing a sport utility vehicle (SUV) tailgate is important aspect of JD (James David) power’s Initial Quality Survey (IQS) assessment, and affective quality has a big impact on the the success of thesedays products. The purpose of this study is to evaluate the perceived difficulty and satisfaction of customers by the opening and closing of the tailgate and to grasp the relationship between them and the opening and closing reaction force. The mechanical force required to open and close 42 domestic and overseas SUV tailgates was measured with the help of an auto company. In the experiment, 100 male drivers in their 20s to 50s evaluated perceived difficulty and satisfaction with opening and closing the tailgate. The results of the analysis showed that perceived difficulty and satisfaction were statistically different depending on the vehicle, but did not depend on the personal characteristics of the participants. The perceived difficulty and satisfaction regression model of tailgate opening and closing was developed by mechanical force variables and had a relatively high adjusted R2 ranging from 0.62 to 0.73. The models showed that the the initial close and open force, the difference between initial and maximum close force and the difference between initial and auto-fall angle should be small for the low perceived exertion and high satisfaction. In addition, the correlation analysis between IQS score of tailages and perceived difficulty and satisfaction showed that the IQS scores were more related to the perceived difficulty and satisfaction of closing than those of opening. The results of the study will be helpful to design and test mechanical open and close structure of SUV tailgates.

실버용 제품 설계를 위한 손의 동작 범위 및 근력에 관한 연구

손병창(Son, Byung-Chang),김혜경(Kim, Hye-Kyung) 한국노년학회 2006 한국노년학 Vol.26 No.1

본 연구의 목적은 고령자의 기능에 적합한 제품을 설계하기 위하여 손의 동작 범위와 근력을 측정ㆍ평가 하는 것이다. 이를 위하여 20연령대에서 80연령대의 여성 227명을 대상으로 하여 손의 동작 4가지에 대하여 요골편향과 척골 편향의 범위를 측정하였다. 또한 물체를 잡을 때의 손의 모양을 3가지로 분류하여 요골 방향과 척골 방향으로 비트는 최대 근력을 조사하였으며, 상관관계 분석을 통하여 동작 범위와 근력에 영향을 미치는 요인들의 관계를 검토하였다. 동작 범위는 20연령대가 가장 크고 근력은 30연령대에서 가장 큰 것으로 조사되었으며 그 후 점차 감소하는 경향이 있었다. 특히 70연령대에서 감소폭이 컸다. 70연령대의 요골 편향의 범위는 20연령대에 비해 30.5%정도 낮았으며, 척골 편향은 그 기능이 상대적으로 오랫동안 유지되어 23.1%정도 낮은 것으로 나타났다. 물체를 잡고 비틀 때의 근력은 요골 방향으로 비틀 때가 척골 방향으로 비틀 때 보다 높게 나타났으며 연령, 잡는 손의 모양, 사용하는 손가락의 수에 따라 차이가 있는 것으로 조사되었다. The present study investigated the range of hand motions and maximum strength of Korean women in wrist operations. A total of 227 women in 20s to 80s participated in the study. The range of hand motions were two twisting directions (clockwise and counterclockwise) and the maximum strength was measured for the combinations of three grip diameters. The women in 30s showed significantly higher maximum torques; a rapid decline was observed in maximum torque for the women aged 70 years or older. In conclusion, the present study determined the maximum strengths in the radial and ulnar deviation are dependent on the types of gripping actions, and their range of actions. It is expected, as a result of this study, that these findings can be utilized as a standard for calculating strength appropriate to humans in the design of tools and products that require actions with radial and ulnar deviation. Specifically, range of hand motions in three types grasp that was not addressed in the previous studies may have significance as a new standard for the design of tools and products.

The need for research on luxury consumption behavior is increasing as individual luxury consumption is expanding among various consumers as a symbolic factor representing their individuality and social status due to the economic development of society and the increase in personal income. Therefore, in this paper, propensity to consume, motivation for purchasing luxury goods, and luxury purchase attitude were investigated and analyzed to study the consumption behavior of the hair designer group. This study directly distributed 400 questionnaires to adults in their 20s and older in Seoul and Gyeonggi Province through a self-response survey, and collected 338 questionnaire analysis data, excluding 62 that were deemed insufficient to analyze. Through reliability analysis and factor analysis, the validity and reliability of hair designers' propensity to consume, motivation for purchasing luxury goods, and luxury purchase attitude were confirmed. In addition, through regression analysis, it was analyzed how propensity to consume, affects motivation for purchasing luxury goods and luxury purchase attitude, and how motivation for purchasing luxury goods affects luxury purchase attitude. As a result of the analysis, it was confirmed that consumers with high ostentatious and planned tendencies are more likely to have an incentive to motivation for purchasing luxury goods, and consumers with reasonable tendencies have a negative relationship with the motivation for purchasing luxury goods. It has also been confirmed that hair designers who want to purchase luxury goods for social or practical purposes have a more positive attitude toward luxury goods. This shows that there is a close relationship between motivation for purchasing luxury goods and purchase attitude, and suggests that consumers' purchase motivation should be considered through strategies that emphasize brand value.
