Glomus tumors are benign tumors that account for 1% to 5% of all soft tissue tumors of the hand and are characterized by a triad of sensitivity to cold, localized tenderness and severe paroxysmal pain. Paroxysmal pain is a symptom common not only in glomus tumors but also in CRPS, and the hand is one of the commonly affected sites in patients with both glomus tumors and CRPS. Therefore, it is not easy to clinically diagnose glomus tumors superimposed on already affected region of CRPS patients. We report a case of glomus tumor concomitantly originating with CRPS at the hand.

We developed the system which could trace the hand and arm motion to test the product usability by integrating a wired-glove and a magnetic position sensing system. The magnetic position sensing system traces the position and orientation of the arm while the sired-glove measures 18 phal angeal joint angles. A case study was performed on two different camcorders in weight. The heavier camcorder was more stable than the lighter one. Also the recording task is more stable than the zoom-in and zoom-out tasks. This system could be used to monitor and quantify the hand and arm motion in real time and also could be used to test the product usability where the hand motion is important.

This article aims to provide information necessary for the measurement and analysis of human vibration, especially hand-arm vibration. The major health problems associated with the use of powered hand tools are the signs and symptoms of peripheral vascular and peripheral neural disorders of the fingers and hands. To prevent these problems, it is the first and the most important to measure the amount of the vibration transmitted to the upper extremities, and analyze its characteristics against the exposure limits such as ISO standards. In our country, however, very few studies have been done on the hand-arm vibration. One of the possible reasons might be lack of knowledge for the measurement and analysis schemes. The information introduced in this article would hopefully be of help for the upcoming studies.

A new method to govern the navigation of a mobile robot is proposed based on the following two procedures: one is to achieve vision information by using a 2 D-O-F camera as a communicating medium between a man and a mobile robot and the other is to analyze and to behave according to the recognized hand gesture commands. In the previous researches, mobile robots are passively to move through landmarks, beacons, etc. To incorporate various changes of situation, a new control system manages the dynamical navigation of a mobile robot. Moreover, without any generally used expensive equipments or complex algorithms for hand gesture recognition, a reliable hand gesture recognition system is efficiently implemented to convey the human commands to the mobile robot with a few constraints.

Unlike printed character, the recognition of Hand written one has various kinds of difficulties due to the existence of the huge pattern associated with the person who writes. Therefore, in general, recognition of Hand written characters requires an algorithm which takes into consideration of the individual differences. Hangul characters are basically made of straight lines and circles. They can be represented in terms of feature parameters such as the end point of the straight line, the length and the angle. Then all Hangul characters can be represented by the number of basic segments(-, /, vertical bar, O) multiplied by the feature parameters respectively. In this study we propose a method for recognizing Hand written Hangul characters in terms of fuzzy inference.

Location awareness is one of the key functions to build an U-city. Recently, many of works for the location-aware systems are emerging to be applied to on-going large-scale apartment complex. For example, when dwellers or cars with active tags are move in the apartment complex, the active tags broadcast their own identifiers periodically and receivers such that routers use this information to calculate the location of the active tags. Since the active tags can actually move between routers and coordinators, it requires a hand-off mechanism. In this paper, we investigate the hand-off problem occurred in location awareness system based on ZigBee active tags. We propose and analyze a new approach for handling the hand-off problem. Through a mathematical analysis, we show that our approach diminishes the quantity of packet transfer than ZigBee's approach.

The purpose of this research was to investigate the motives of second-hand clothing consumers who both purchase from and donate to one retail outlet. Individuals' purchasing and donating motivations were examined using the hedonic/utilitarian framework. Eighteen participants who had donated to and purchased second-hand clothing from a charitable organization's thrift store were purposively selected and interviewed. Themes that emerged during data analysis were used to categorize the participants. The participants' responses suggested that hedonic and utilitarian motives drove both donation and purchase behavior. Academic and practical implications are presented.

The drinking manners of the modern generaton were reviewed based on historical records. First, for reasons of health, we should reject the drinking from the same cup as others in reciprocation. Second, if the other people are older or younger brothers above the same level, pouring with one hand is all right, but if 5 years older or more, or stranger, grasp the bottle in two hands in the following manner. With the right hand under the bottle, and the left hand supporting its side, carefully pour wine not to show the palm of the hand. Third, ladies, also, can drink freely at the same table, but if people of the opposite sex are sitting together, they should pour with two hands to convey the meaning of courteous treatment. Fourth, because the level of our living is not two high, we must not order more them we can use, so that when we are finished, there will be no remainder.

The purpose of this study was to examine the effects of chemical finishes on performance characteristics of microfiber blend fabrics. A 60% polyester microfiber /40% cotton blend woven fabric was finished by ten chemicals: three silicone softeners, one fluorochemical, and their mixtures. Performance characteristics examined were fabric hand attributes. Fabric hand was evaluated by instrumental measures using Kawabata KES-F system instruments. Silicone-only finishes did not change the bending properties significantly from those of the control fabric. The fluorochemical-only finish made the fabric stiffer and crisper. When the two chemicals were mixed they tended to offset this adversary effect. Most of the chemical finishes made the surface finer and smoother. Fluorochemical-only finish improved fabric strength. Likewise, dimethylpolysiloxane silicone improved fabric strength. Amino-functional hydrophilic and diamino-functional silicone softeners, on the other hand, reduced fabric strength. However, when mixed with the fluorochemical, the adversary effect was diminished.

Turrets exostosis are extremely rare to occur. Benign bony outgrowths from the dorsum of the phalanges following trauma are termed Turrets exostosis. We report an unusual case of Turrets exostosis of the fourth finger with no preceding trauma which has never been reported before. A 50-year-old female patient presented to us with a bony swelling on the dorsum of the fourth finger of her right hand in one year. The swelling was dormant initially and started to progress in size since three months leading to pain, restriction of movements and deformity of the finger. Turrets exostosis are very rare to occur. A preceding history of trauma is not necessary for it to occur as described in the literature. Surgical excision yields good results and is indicated when the bony mass causes a progressive deformity of the finger and restriction of movements of the finger.
