  • 백설기의 제조 시 쌀가루의 체질 방법이나 횟수에 따른 제품의 품질 특성을 CrumbScan을 이용한 객관적인 영상분석 방법으로 알아보았다. Tiff file로 처리된 영상분석의 결과, 체질을 한 경우가 제품의 속질이 부드럽고, 특히 손 체질을 하는 경우가 가장 제품의 상태가 좋아지는 것으로 나타났으며, 제조상의 실수도 줄일 수 있는 것을 알 수 있었다. 특성의 분석 결과, 체질을 할 경우 대조구와 비교하여 제품의 부피는 작아졌고, 무게도 가벼워졌으며, 2회의 손 체질과 1회의 기계 체질이 적합한 것으로 나타났다. 속질의 조밀함은 손 체질의 경우 높게 나타났으나, 기공의 형태가 찌그러짐을 보여주었다. 특성들 간의 관계를 살펴보면, 손 체질을 하는 경우에서 부피와 무게에 부의 관계가 나타나기도 했지만 큰 영향을 주지는 않으며, 기계 체질의 경우에는 부피와 다른 특성들 간에는 관계가 나타나지 않았다. 결론적으로 손을 이용한 전통적인 체질 방법이 백설기의 제조에 좋은 것으로 나타났으며, 전통적인 방법과 기계적인 방법의 혼용도 연구가 되어야 한다고 사료되었다.

  • This paper describes the intelligent robot's hand with three finger sensors for a humanoid robot. In order to grasp an unknown object safely, the intelligent robot's hand should measure the mass of the object, and determine the grasping force using the mass, finally control the grasping force using the finger sensors and the controller. In this paper, the intelligent robot's hand for a humanoid robot was developed. First, the six-axis force/moment sensor was manufactured. second, three finger force sensors were designed and fabricated, third, the high-speed controller was manufactured using DSP(digital signal processor), finally, the characteristic test for determining a grasping force and for grasping an unknown object safely It is confirmed that the hand could grasp an unknown object safely.

  • Purpose: The purpose of this study was to identify the effect of hand moxibustion for reduction of pain during menstruation. Method: Fifteen women were selected as subjects and data collection was conducted from September to December 2003. The Visual Analogue Scale (VAS) and Digital Infrared Thermotraphic Image (DITI) were used to measure the degree of pain and body heat. Result: The results showed that there was a significant reduction of pain during menstruation when hand moxibustion was performed. Also, there were significant differences in the change of body heat. These were left hands (Z=-2.805, p=.005), right hands (Z=-2.805, p=.005) and lower abdomen (Z=-2.803, p=.005). Conclusion: It was found that hand moxibustion decreased pain during menstruation and increased body heat. Therefore, hand moxibustion may be a good method for intervention to decrease pain during menstruation.

  • 현대 커뮤니케이션 디자이너는 시각적 혹은 형태적인 운영이나 해석은 물론 컨텐츠의 개발과 스토리 텔러로서 의 역할이 요구된다. 그러나 커뮤니케이션 디자이너들에게 있어서 컨텐츠를 이루는 이야기 구조에 대한 이해와 실험은 아직도 미미한 상태이다. 특히 디지털 기술의 급속한 발달로 인하여 80년대부터 타이포그라피의 영역은 정적인 형태에서 역동적인 형태를 갖는 Type in Motion으로 빠르게 전이되고 있다. 이에 스토리의 내용과 구조를 가장 잘 표현 할 수 있는 수단으로서의 Type in Motion에 관한 체계적인 연구가 필요하게 되었다. 본 논문은 이러한 컨텐츠로서의 스토리를 형태로서의 Type in Motion 기법을 이용해서 어떻게 효과적으로 표현 할 수 있는가를 연구한 것이다. . Type in Motion의 구성요소를 통해서 스토리의 함축적인 표현 방법과 기능적인 표현 방법을 분석하였다. 오늘날 디지털 기술이 디자이너에게 많은 혜택을 가져다 준 것은 사실이지만 한편으로는, 디지털 디자인의 효율적인 운영을 위해서는 다양한 분야의 지식이 필요하다. 따라서 디지털 타이포그라피를 다루는 디자이너도 시각언어로서의 Type in Motion뿐 아니라 음성언어로서의 Type in Motion에 대한 이해와 연구가 필요하다. 이런. 관점에서 스토리와 Type in Motion를 전체론 적 관점에서 해석하고 이들의 유기적 관계를 탐구하는 것은 효과적인 디지털 타이포그라피의 운영에 있어서 필수적이라고 하겠다.

  • 본 논문의 목적은 코로나-19 이후 뮤지엄 운영이 차질을 빚고 있는 상황에서 발달하고 있는 VR 전시의 한계에 대해 논의하고, 그 대안으로 현재까지 소개된 여러 유형의 AR 전시를 뮤지엄 중심으로 연구하여 코로나 시대에 디지털 콘텐츠가 어떻게 효과적으로 변화하고 활용될 수 있는지 알아보는 데 있다. VR/AR 전시를 코로나-19를 전후로 살펴본 결과, VR은 대부분 현실을 동영상으로 촬영하여 소개하고 있어 미학적 현장감부재와 HMD 장비운영 문제를 드러낸다. 주로 보급률이 높은 모바일을 이용한 AR은 특정 실내 공간에서 콘텐츠를 감상할 수 있는 '뮤지엄용', 개방된 실외 공간에서 이용할 수 있는 '특정 장소형', 디지털 콘텐츠와 인쇄물에 접목하여 우편형식으로 발송 가능한 '불특정 장소형'으로 나누어 볼 수 있다. 이중 특정/불특정 장소형은 실외 공간 및 우편 발송을 통해 가장 높은 비대면 효과를 나타내고 있어 펜데믹 시대의 효율적인 뮤지엄 콘텐츠 개발 방향을 제시할 수 있다.

  • Background Hand strength deficit following digital replantation is usually attributed to the mechanical deficiency of the replanted digit. Zone 1 replantation, however, should not be associated with any mechanical deficit, as the joint and tendon are intact. We evaluate shortterm motor functions in patients who have undergone single-digit zone 1 replantation. Methods A single-institution retrospective review was performed for all patients who underwent zone 1 replantation. Hand and pinch strengths were evaluated using standard dynamometers. Each set of measurements was pooled according to follow-up periods (within 1 month, 1 to 2 months, 2 to 3 months, and after 3 months). The uninjured hand was used as reference for measurements. Results The review identified 53 patients who had undergone zone 1 replantation and presented for follow-up visits. Compared to the uninjured hand, dynamometer measurements revealed significantly less strength for the hand with replanted digit at one month. The relative mean grip, pulp, and key pinch strength were 31%, 46%, and 48% of the uninjured hand. These three strength measurements gradually increased, with relative strength measurements of 59%, 70%, and 78% for 4-month follow up. Conclusions Despite the lack of joint or tendon injury, strength of the injured hand was significantly lower than that of the uninjured hand during the 4 months following replantation. Improved rehabilitation strategies are needed to diminish the short-term negative impact that an isolated zone 1 replantation has on the overall hand strength.

  • Shoulder hand syndrome is characterized by pain, vasomotor instability, and tenderness, mainly in the distal upper extremity. The pathophysiologic mechanism of this syndrome is not yet proved. The purpose of this study is to evaluate the usefulness of thermographic imaging on shoulder hand syndrome after stroke for early diagnosis and its clinical pattern analysis including acupuncture and electroacupuncture therapy. This study was performed from June to September in 1996 on 46 stroke patients who were admitted at Oriental hospital of Kyung Hee Medical Center. The study group were 23 patients with shoulder hand syndrome. The control group were 23 patients without shoulder hand syndrome. Skin temperatures on the both upper extremities were measured by Digital Infrared Thermographic Imaging(D.I.T.I.) before the study and 3 weeks later again. The results were as follows; 1. The shoulder hand syndrome group were significantly more restricted in shoulder passive range of motion than the control group. 2. The shoulder hand syndrome group showed significant temperature difference of both dorsal hands. 3. The electroacupunture therapy group were significantly more improved on the temperature difference of both dorsal hands than acupuncture therapy group in 3 weeks later. 4. Both posterior arms showed the biggest temperature difference from 11 to 30 days in shoulder hand syndrome group. 5. The lesser passive ROM(range of motion) of shoulder group showed significantly increased temperature difference of both hands. The above results show that measurement of shoulder passive range of motion and D.I.T.I. is a useful method for early diagnosis on shoulder hand syndrome and its clinical pattern analysis including evaluation of acupuncture and electroacupuncture therapy. Continuous study will be needed for more clinical application and evaluation on shoulder hand syndrome.

  • In this study, six grip spans (45mm-65mm) were tested to evaluate the effects of handle grip span and user's hand size on maximum grip strength, individual finger force, and subjective ratings of comfort using a digital dynamometer with individual force sensors. Forty-six males were assigned into three hand size groups according to their hand lengths. Results showed that overall 55mm and 50mm grip spans were the most comfortable sizes and associated with the highest grip strength in the maximum grip force exertions, whereas 65mm grip span was rated as the least comfortable size as well as the lowest grip strength. In the interaction effect of grip span and hand size, small and middle hand sized participants rated the best preference and the least preference grip spans differently with large hand sized participants. With respect to the analysis of individual finger force, the middle finger force was the strongest and the highest contribution to the total finger force, followed by ring, index and little fingers. In addition, it was noted that each finger had a different optimal grip span for exerting maximum force resulting in a bowed contoured shaped handle for two-handle hand tools. Thus, the grip spans for two-handle hand tools might be designed according to the users' hand and finger anthropometrics to maximize performance and subjective perception of comfort.
