  • Purpose: The aim of this study was to present specific criteria for setting goals for hand rehabilitation by comparing the degree of difference in grip force, coordination, and dexterity between the dominant and non-dominant hand according to gender. Methods: We recruited 100 healthy adults in their 20s and 30s. A handheld digital dynamometer was used to evaluate the grip force of each of the dominant and non-dominant hand, a chopsticks manipulation test was used to evaluate coordination, and the Purdue Pegboard test was used to evaluate agility. Results: In all subjects, the grip force, coordination, and dexterity showed statistically significant difference (p <0.01) between the dominant and non-dominant hand. In the comparison according to gender, both male and female dominant and non-dominant hands showed statistically significant differences in grip force, coordination, and dexterity (p <0.01). In the comparison according to grip force, there was a statistically significant difference between the dominant and non-dominant hand, and men showed stronger result values in both hands compared to women (p <0.01). In the comparison according to coordination, there was no statistically significant difference between the dominant and non-dominant hand in men and women (p >0.05). In the comparison according to dexterity, there was a statistically significant difference between the dominant and non-dominant hand, and women were shown to be faster in performance time with both hands, compared to men (p <0.01). Conclusion: Differences according to gender exist in grip force and dexterity but not coordination, and differences between dominant and non-dominant hand exists across all measurements.

  • 사회 변화의 가장 중요한 원인 중의 하나는 세대 간 차이이다. 어떠한 대상에 대해 연령대별로 어떠한 인식을 지니고 있는가를 살펴보는 것은 그 대상이 현재 어떤 상태이고, 또 앞으로 어떤 방향으로 나아갈지에 대한 시금석이 될 수 있다. 따라서 본 연구에서는 연령대별로 규제 인식에 대한 차이가 존재하는지를 살펴보고자 한다. 연령대별 규제인식 차이 여부를 검증하는 것은 우리 사회의 규제 현상을 이해하는데 도움을 줄 수 있다. 분석결과 규제에 대한 인식은 연령에 따라 차이가 존재하고 있다. 연령대가 높을수록 규제에 대해 긍정적인 성향을 보이고, 연령대가 낮을수록 규제에 대해서 부정적인 인식을 지니고 있다. 특히 규제의 전문성 부문과 대기업에 대한 규제 등에 대해서는 50대와 20대가 서로 반대로 인식하고 있었다. 규제에 대해서 연령차이가 존재한다는 것은 규제 정책 제정 및 집행과 관련해서 보다 다양한 측면을 고려할 필요가 있다는 점을 제시한다.
