Recently, due to the popularization of 3D depth cameras, new researches and opportunities have been made in research conducted on RGB images, but estimation of human hand pose is still classified as one of the difficult topics. In this paper, we propose a robust estimation method of human hand pose from various input 3D depth images using a learning algorithm. The proposed approach first generates a skeleton-based hand model and then aligns the generated hand model with three-dimensional point cloud data. Then, using a random forest-based learning algorithm, the hand pose is strongly estimated from the aligned hand model. Experimental results in this paper show that the proposed hierarchical approach makes robust and fast estimation of human hand posture from input depth images captured in various indoor and outdoor environments.

This paper presents a novel diagnostic method to determine Sasang Consitution (SC) by elasticity coefficient of hand dorsal skin of elderly people. For this purpose, we carried out a clinical test, in which Our SC diagnostic tool and one Oriental medical doctor with SC medicine expertise participated to categorize 458 healthy subjects into four constitutions. After excluding heavy-noise, we extracted 295 subjects' elasticity coefficient feature data and statistically analyzed their SC relevance with ANOVA test. It resulted in that, Taeum-in has high elasticity coefficient compared to Soeum-in in a significance level of 0.05. There are no differences of elasticity coefficient in genders. This result is supported by the theory of Longevity and Life Preservation in Eastern Medicine(Donguisusebowon, 동의수세보원) which suggested that Taeum-in's flesh is solid and Soeum-in's one is tender. This is the first work which reports the relatedness of skin elasticity coefficient and SC by an objective clinical test.

According to Post-modernists including deconstructivists, as Modernism is changed into Post-modernism, the paradigm is shifted from consciousness to language. The paradigm of consciousness corresponds to representational language, and the paradigm of language to self-referential one. In post-modern age most of architects are wandering what kind of language architecture is. Some theorists contend that architecture is representational, and others that it is self-referential. Allan Colquhoun, who is known as one of the best architectural theorists inUnited States, accepts both the former and the latter, but fails to reveal the meaning and the limitation, of the two languages. Although he believes that the representational language of architecture ('figure') is the source of self-referential language of architecture('form'), he never clearly answers what kind of language architecture. In order to overcome the limitation and the meaning of Colquhoun's figure and form, and synthesize the two language, this essay appropriates Martin Heidegger's some concepts, 'ready-to-hand,' 'present-at-hand' and 'being-in-the-world' to make a theoretical framework for 'image' which prevails over and synthesizes 'form' and 'figure.' Since Image is based upon both 'being-in-the world' and 'ready-to-hand,' it is the source of 'form' and 'figure.' When 'image' is fragmented, the former and the latter emerge. Image is therefore both the former and the latter because it represents and self-refers a world as a reality.

Pulp and palm of the hand and heel of the sole are anatomically unique. Satisfactory reconstruction of these areas presents the plastic surgeon with many challenges and requires durable and sensible skin coverage, minimal donor morbidity and reliable operative procedure. We presents 7 clinical cases of sensate instep free flap transfer in this paper during the last 2 years. Three cases were soft tissue defects due to crushing and avulsion injury on the pulp of finger. 1 case was unstable scar and redundant flap after reconstruction of soft tissue dect of palm and 1 case was contracture of first web of hand. One case was a soft tissue defect due to avulsion injury on heel. Lastly, one case was chronic osteomyelitis with open wound on lateral malleolar area. Follow-up period ranged from 3 months to 2 years. Through the whole follow-up period, all flaps were viable and durable to persistant stress or weight bearing and were sensible enough to porotect the recocstructed area from injuries and maintain functions. In conclusions, the instep free flap should be considered as a valuable tool in reconstruction of hand and extremity requiring durability and sensation.

Cheiro-oral syndrome is characterized by a partial sensory disturbance in one hand and the ipsilateral oral comer. Its lesion is on the sensory track, and it is comparatively small. Most studies are case studies. These studies reported less than 10 cases. We studied two cases. In one, we observed intracranial hemorrhage involving left thalamus, posterior limb of internal capsule about 5cc in brain computed tomographic scan. The case was shown paresthesia of the right hand and ipsilateral comer of the mouth. The patient also complained about disturbing dysstereognosis and disorder of graphaesthesia. In the other case, we observed nodular calcification at the left basal ganglia external capsule in brain computed tomographic scan. The patient also complained about dysesthesia of the right thumb and index finger, fatigue and verbal disturbance. These cases appeared to be typical strokes in the acute phase, but after acute phase, they had dysethesia in the hand and periord for three months.

This study was carried out to investigate sound characteristics including sound parameters and subjective sensation, and primary hand values related with sound of fabrics for blouse, and furthermore to predict subjective sound sensation with mechanical properties and sound parameters. Sound of specimens was analyzed by FFT. Level pressure of total sound(LPT), loudness(Z), coefficients of autoregressive(AR) functions for fitting the spectra, and sound color factors(ΔL and Δf) were obtained as sound parameters. Primary hand values for women's thin dress were calculated by using KES-FB. Subjective sensation for sound including softness, loudness, sharpness, clearness, roughness, highness, and pleasantness was evaluated by free modulus magnitude estimation. The results were as follows; 1. Fabrics for blouse showed similar spectral shapes to one another in that amplitude values were lower in most ranges of frequencies than fabrics for other uses. 2. It was found that fabrics for blouse were less louder because LPT, loudness(Z), and ARC values were lower than other fabrics. 3. Primary hand values indicated that specimens were soft-touched, flexible, and less crisp. Among primary hands related with sound, Shari values were higher for silk fabrics than for synthetic ones, while the values for Kishimi were similar, 4. Fabrics for blouse were rated more highly for softness, clearness, and pleasantness than for loudness, sharpness. roughness, and highness. Silk fabrics were evaluated more pleasant than synthetic fabrics. 5. Subjective sensation for sound of blouse fabrics were predicted with mechanical properties and physical sound parameters.

Beau first described transverse depressions of the fingernails after an acute febrile illness in 1846. It was the result of the temporary arrest of nail matrix formation. The transient interference of nail growth rate is usually induced by disability caused by severe systemic disease. Such as Raynaud disease, myocardial infarction, pulmonary embolism, acute renal failure, psoriasis and dysmenorrhea were reported to be the cause of Beau's line. The trauma caused either in a hand or in a forearm was also reported to be the cause of Beau's line. We experienced patients with Beau's line, two cases secondary to fingertip injury and one case due to fracture in radius. They had Beau's lines in all fingers of traumatized hand and nails of opposite hand were normal. During the follow-up, the growth rate of traumatized fingernails were normal and there was no complication.

In order to evaluate performance of anti-vibration gloves, it is necessary to measure the transmitted vibration to the hand and the applied forces at the same time while gripping the vibrating handle. In the study a system was developed to measure both the vibration and the forces. The system consists of a measurement handle with eight strain gauges and two accelerometers and a PC-based system with a software for signal processing, evaluation of the hand-transmitted vibration and for control of applied forces in the pre-determined range. The handle was installed on the vibration shaker which is strong enough so as not to be affected by dynamic coupling with the hand-arm. Whole procedure of ISO 10819:1996 to determine the vibration transmissibility of anti-vibration gloves was programmed into the system. As an example of the application, three subjects joined the test to get vibration transmissibilities of 9 anti-vibration gloves where each glove was tested twice a subject. Average and standard deviation of the corrected vibration transmissibility were also calculated. All tested gloves fulfilled criterion for M-spectrum($\overline{TR_M}$<1.0), but one glove fulfilled criterion for H-spectrum($\overline{TR_H}$<6.0),

The shoulder joint permit ate greatest mobility of any joint area carries out the importment function of stabilization for hand use. So handgrip activity is important to evaluate while assessing shoulder load in manual work. There was an association between static handgrip and shoulder muscle activity. The purpose of this study was to find out the changes of the hand grip strength according to shouter an81e. One hundred (50 female, 50 male) college adult volunteers with no known shoulder dysfunction participated subject in three positions with elbow extension: (1) shoulder $0^{\circ}$ flexion (2) shoulder $90^{\circ}C$ flexion (3)shoulder $180^{\circ}C$ flexion. The paired t-test was used to determine the different in grip strength between right and left hand at shouter position change. All, there was significiant for all three position by right and left shoulder (p<0.001). In mon, the ANOVA results revealed not a significiant F-ratio fer all three position by right and left hand. In woman, revealed significiant (p<0.05).
