The definition of the 'Pocket', according to the Korean encyclopedia, is an accessory that a person puts in small belongings or money and carry on waist or holds with a hand. Since the pockets were not attached to the clothes at that period of time, the portable bag or pocket had been used without distinction of age or sex for carrying personal belongings. The pocket in France was also used in a similar manner, where it was used as a handbag to carry purse, comb, or a key by women during the middle ages. The pockets were decorated, made of quality material such as velvet, silk, or satin with splendid embroidery or beads. This study closely examines the history of the pocket from late 16th century around Renaissance to early 20th century in France and during the mid Cho-Sun dynasty in Korea and compares the different kinds of patterns, symbolism, and the purpose of the pockets. In addition, the relationships between the pockets, belongings, and ornament are examined as well by thoroughly investigating the unique characteristics of the pocket of each country.

PURPOSE: This study aims to examine the impact of the location of a walker-aid pocket that is attached to the walker while walking. METHODS: The research subjects included 10 male adults and 10 elderly people. The subjects used a two-wheeled walker for the walking analysis, and a firm velcro-type pocket that can be attached to the walker aid was used for weight loading. The size of the external loads was set at 2kg, which corresponds to approximately 2.5% of the mean body weight of the subjects. The pocket was attached to the left, center, and right sides of the walker aid. Stride length, stride, step width, and time were investigated according to the location change. RESULTS: No statistical differences were observed in all the walking factors among the adults and elderly people regardless of the changes in the location of the walker pocket. In cases of no weight and the 2kg walker pocket, stride length and strides were longer for the adults, while the step width was greater and walking time was longer for the elderly people. CONCLUSION: The weight of the walker pocket turn out to retard walking speed, although the location of the walker pocket is not affect walking with the walker-aid.

This study was conducted to estimate the amounts of the electromagnetic wave penetrating from a cellular phone in a pocket of dress shirt, as well as to test how different the penetration amounts were under the conditions of wearing. It was also investigated the possibilities that the amounts of the electromagnetic wave penetrating could be decreased by using twofold pocket or electromagnetic wave free fabric. The amounts of the electromagnetic wave penetrating were measured in the following five cases; one-layered pocket with 10 different fabrics as dress shirt, a pocket adding a layer of knitted cotton, two-layered pocket with same fabric as dress shirt, two-layered pocket adding a layer of knitted cotton, and one-layered pocket adding a layer of electromagnetic wave free fabric. Each of these five cases were measured using the front and back sides of a cellular phone facing to the body. The results were as follows; 1) The amounts of the electromagnetic wave penetrating were not significantly different in 10 different fabrics and were all above the caution range (0.02mW/$cm^2$). 2) The amounts of the electromagnetic wave penetrating in cases of the back side of the cellular phone to the body, were more than in cases of the front side. 3) There is a significantly differences in part on adding a knitted under wear to one and two layers of the pocket in the case of penetration amount under the wearing conditions. 4) The amounts of the electromagnetic wave penetrating in cases of adding a layer of electromagnetic wave free fabric, were close to the safe standard value of it. The above results suggested that facing the front side of cellular phone to the body and using extra layering with some electromagnetic wave free fabrics might have some protective effects again to the penetration amounts.

The conformational dynamics of heme pocket, a small vacant site near the binding site of heme proteins -myoglobin (Mb) and hemoglobin (Hb), was investigated after photolysis of carbon monoxide from MbCO and HbCO in D$_2$O solution at 283 K by probing time-resolved vibrational spectra of photolyzed CO. Two absorption bands, arising from CO in the heme pocket, evolve nonexponentially in time. The band at higher energy side blue shifts and broadens with time and the one at lower energy side narrows significantly with a negligible shift. These spectral evolutions are induced by protein conformational changes following photolysis that modify structure and electric field of heme pocket, and ligand dynamics in it. The conformational changes affecting the spectrum of photolyzed CO in heme pocket likely modulates ligand-binding activity.

In process planning for pocket machining, the selection of tool size, tool path, overlap distance, and the calculation of machining time are very important factors to obtain the optimal process planning result. Among those factors, the tool size is the most important one because the others depend on tool size. And also, it is not easy to determine the optimal tool size even though the shape of pocket is simple. Therefore, the optimal selection of tool size is the most essential task in process planning for machining a pocket. This paper presents a method for selecting optimal toos in pocket machining. The branch and bound method is applied to select the optimal tools which minimize the machining time by using the range of feasible tools and the breadth-first search.

Pocket machining is metal removal operation commonly used for creating depressions in machined parts. Numerically controlled milling is the primary means for machining complex die surface. These complex surfaces are generated by a milling cutter which removes material as it traces out pre-specified tool paths. To machine, a component on a CNC machine, part programs which define the cutting tool path are needed. This tool path is usually planned from CAD, and converted to a CAM machine input format. In this paper I proposed a new method for generating NC tool paths. This method generates automatically NC tool paths with dynamic elimination of machining errors in 2$\frac{1}{2}$ arbitrary shaped pockets. This paper generates a spiral-like tool path by dynamic computing optimal pocket of the pocket boundary contour based on the type and size of the milling cutter, the geometry of the pocket contour and surface finish tolerance requirements. This part programming system is PC based and simultaneously generates a G-code file.

The purpose of this study is to evaluate the combination of suit details through visual evaluation which helps compensating middle aged womens body defects for their more attractive fashion styles. In this study, styles of the evaluated suits are formal and classical. The designs of evaluated suits are manipulated in 40 different kinds by the essential elements such as collars, necklines(tailored collars, soutien collars, stand collars, round necklines, V-necklines), bottoms(slacks, skirts), pocket(flap pocket, none) and opening(opened, closed). The data evaluated by a multiple ranking test were analyzed by mean, paired t-test, ANOVA and Duncans multiple raged test. The results are summarized as follows: 1) The classic style suits-middle aged womans body construct looks better when she is wearing it with the combination of suit details; opened tailored collar jacket with flap pocket or non-pocket, opened stand collar jacket with non-pocket, closed soutien collar and round neckline jacket with non-pocket, closed V-neckline jacket with flap pocket or non-pocket on slacks. 2) The middle aged woman wearing slacks looks smaller in upper body, longer in lower part of her body and taller as a whole than when wearing a skirt suit. And Opened jacket makes a middle aged woman be seen with less appeared abdomen than that on closed jacket. The stand calar and round neckline jacket with non-flap pockets makes her look smaller in upper body and hip. 3) With tailored, soutien, stand collar jacket, it looks slimmer in a neck, narrower in shoulder, smaller in upper body, and taller than on a round neckline and V-neckline jacket.
