Peg-in-hole assembly is the most representative task for a robot to perform under contact conditions. Various strategies for accomplishing the peg-in-hole task with a robot exist, but the existing strategies are not sufficiently practical to be used for various assembly tasks in a human environment because they require additional sensors or exclusive tools. In this paper, the peg-in-hole assembly experiment is performed with anthropomorphic hand arm robot without extra sensors or devices using "intuitive peg-in-hole strategy". From this work, the probability of applying the peg-in-hole strategy to a common assembly task is verified.

A clothing-erogonomics study was performed to investigate the difference of the upper arm skin skin surface and the relationship among the three aspects of upper arm (height of sleeve rap, sleeve width and armhole girth) by changing arm movements. Plaster cast was used for this experimental research. Arm movements consist of 9 types; just carmly standing on ($0^{\circ}$), and each 4 types ($45^{\circ},\;90^{\circ},\;135^{\circ},\;180^{\circ}$) to the vertical direction in front and in side. The results were as follows; 1) As the arm-movement angle increased, the height of sleeve cap decreased and that ratio was largest in the portion A-B3. 2) The steeve width was enlarged with the increment of movement angle in all portions of upper arm except B1-B5. 3) As increasing the movement angle, the whole armhole girth decreased and the ratio o(front armhole girth (F-A) was larger than that of back. 4) In the vertical direction in front, the height o( the sleeve caps was larger, the sleeve widths were smaller than in the vertical direction in side in all movement types, but there was no significant difference in arm-hole girth between the two cases. 5) There were significantly negative relationships between measurements in height of sleeve cap and those in sleeve width, and also between those in height of sleeve cap and in arm-hole girth. And significantly positive relationships were found between neasurements in height of sleeve cap and those in arm-hole girth.

The purpose of this study is to analyze present the pattern making of the lining fabrics calculating the right ease and rising quantities of arm-hole when the pattern of the lining fabrics of stretchable jacket fabrics is produced. The outcomes of this study are as follows. The right ease of lining fabrics was not room of 0cm as patterns being same the right side of fabrics in the girth of the chest, waist, and the edge of a garment and gets the most excellent valuation, and then the girth of the chest, and waist was applied to 2cm and around the edge of a garment 0cm in regular lining fabrics. In addition to, although the ease of patterns of the lining fabrics was more, it was not necessarily to satisfy. The result of the valuation according to the quantities of rising arm-hole of the pattern of the lining fabrics showed that the making lining fabrics that the quantities of rising arm-hole was 0.8cm in the body and 1.2cm in the sleeve in the both the stretchable fabrics and regular lining fabrics was the most excellent thing, and then 0cm in the body and 2cm in the sleeve, and then 0cm in the body and 0cm in the sleeve. The valuation of external appearance on the quantities of rising arm-hole was recognized similarly because of being rarely significance level, but around the chest and waist was recognized as being significance level in wearing satisfaction.

During the intramedullary nailing procedure, surgeons feel difficulty in manipulation of the X-ray device to align it to axes of nailing holes and suffer from the large radiation exposure from the X-ray device. These problems are caused by the fact the surgeon cannot see the hole's location directly and should use the X-ray device to find the hole's location and direction. In this paper, we proposed the robotic guidance of the distal screwing using an optical tracking system. To track the location of the hole for the distal screwing, the reference marker is attached to the proximal end of an intramedullary nail. To guide the drill's direction robustly, the 6-degree-of-freedom robotic arm is used. The robotic arm is controlled so as to align the drill guiding tool attached the robotic arm with the obtained the hole's location. For the safety, the robot's linear and angular velocities are restricted to the predefined values. The experimental results using the artificial bones showed that the position error and the orientation error were 0.91 mm and $1.64^{\circ}$, respectively. The proposed method is simple and easy to implement, thus it is expected to be adopted easily while reducing the radiation exposure significantly.

Clothing must have the individual beauty and the function that one can do one's body movement freely. therefore, from the human engineering view point, the exact measurement of the human body and the analysis of it's results must be applied to clothing because the arm works most. In this study, the skin surface of arm was investigated by shell made of Alginate of each movement. And by sometic method the rate of expansion and contraction of each section, inter-relation among the bust girth, axillary arm girth and scye girth and between the shoulder length right and the under axilla waist length were calculate4d. With these results, cap height, breadth of a sleeve and arm hole girth of existing sleeve pattern have been compared and analysed. The results are as follows; 1) According to the developmental figures of shell, the whole area change was small but that of shape was remarkable in M 4, 9, 13. The change of the Block 1 was particular. 2) Over arm length was contracted in all movements except M6 and under arm length expanded. The changes of sections a, b, c are large, while those of sections d, e are small. 3) In terms of latitudes, change of fore-arm region was small. The rate of scye girth varied from 14.3% of M13 to-5.6% of M2. The breadth of a sleeve expanded in all movements, and especially the front region expanded more than the back. 4) The relation between the shoulder length right and under axilla waist length, in all occasions, was contracted mutually, and one contracted, the other expanded. Therefore, in clothing construction when we consider the function of the arm it is better to widen the arm hole and the breadth of a sleeve at the same time than no widen the shoulder length by lowering the upper part of the upper side seam line.

This paper is intended to grasp the characteristics of many bodices patterns which have been shown so far. The way is by selecting four characteristic kinds of patterns, making blouses offer the patterns and measuring ease. In measuring the degree of ease, $Scheff\`{e}'s$ paired comparison is made use of. In analysis, variation ratio has come out of analysis of variance, and significance is tested by producing estimated values between patterns. The Result is summed up as follows. 1. After wearing blouses made ofter different basic patterns and measuring ease, the analysis of variance is made about the sensory value of ease. The result is as follows. 1) In the ease of different patterns, all the areas are significant at the level of $1\%$ , regard- less of movements. 2) Under the influence of movements, the back area of arm hole is significant at the level of $5\%$ in narrow movements, and the front and the back area of arm hole are each significant at the level of $1\%$ in wide movements. 3) In the interaction of patterns and movements, bust and the under area of arm hole are each significant at the level of $1\%$ in narrow movements, and bust is significant at the level of $1\%$ in wide movements. 2. When comparing estimated values between patterns, the value of c is the largest and in the order of b,4, a. And in the other movements, the order changes into c,d, b and a. Thus the ease of blouses is different according to patterns. The reason for this is that the amount of ease of bust, the amount and location of darts, and sleeve cap height have complicate influences on the ease of blouses. Both sleeve cap height and the depth of arm hole have influences on the ease of sleeve. Consequently, in making clothes, it would be better to select and use proper patterns which go with the purposes and desings of clothes rather than to apply one pattern to various clothes.

The purpose of this study is to compare and analyze methods of women's apparel prototypes and provide for some useful fundamental data to improve the apparel prototype suitable for Korean women. Two different drafting methods, the Bunka pattern of Japan Bunka Women's University and the Secoli pattern of Italy istituto carlo secoli, an italian pattern drafting institute, were selected. The result and discussion are as follows; In the calculation formula, the Bunka was shown more comfort at arm-hole part, because of it's lower arm-hole depth, wider arm-hole width and lower cap height in comparison with the Secoli. At the shoulder angle, the Bunka is inclined more in front shoulder than the back shoulder, whereas the Secoli is inclined more in back shoulder than the front shoulder. It could explain that the Bunka is suitable for bendforward type and the Secoli is suitable for lean-back type. In the sensory test, the one-piece pattern of the Secoli with 4cm ease was highly estimated in ease. It seems young women's preference to body conscious clothes which reflected in many new elastic fabrics. At the bust point to neck, the Bunka was highly estimated, compared with the Secoli. It seems like to be caused that for the bust point to neck formula, the Bunka used bust girth, the Secoli used stature which has low correlation with the bust point to neck.

The subject, in the blouses that sleeve caps and sleeve lengthes are different from, did sensory test by right arm movement and both arms movement. This sensory test which is used in fabric good, is Shef's. RESULTS : 1) The ease of bust size is very significant by cap height, at 5%, 1% level by sleeve length. 2) The front area of arm hole is affected by cap height, sleeve length movements more than the back and the under area of arm hole are 3) Sleeve width is affected by cap height, sleeve length both arms movement. That is, they should be designed according to the use because they affect the ease of blouse very much. Especially bust size should be considered with sleeve pattern because the ease bust becomes different with sleeve pattern.
