This study aims to survey the satisfaction level with the fit of ready-made suits(jackets and pants) among adult males and thereby to show its differences by the age group and body type. The respondents to the questionnaire survey were 465 males, aged 20 through 59 years. The conclusions are as follows: 1. The average satisfaction level for the fit of each item ranged from 2.65 to 3.57, with the higher level found in jackets than in pants, and also in circumference parts than in length parts 2. The satisfaction level for the fit by the age of adult males showed inter-group differences in the parts of jacket length, sleeve length, shoulder width, sleeve openings, and sleeve band width for jackets; and pant length of pants. 3. The satisfaction level for the fit by the body type of adult males indicated into-group differences in chest circumference of jackets only. 4. The satisfaction level for the fit, with the exclusion of the age and body type relationship showed that adult males are affected more by the age than by the body type. 5. In the repair frequency by the item, pants(45.6%) showed a higher level than jackets(24.7%). The parts with a high repair level by the item were jacket length(8.4%) and steeve length(19.8%) for jackets; and pant length(42.4%) and waist circumference(8.4%) for pants.

The purpose of this study was to design men's jacket pattern for variable body types by employing the data of wearing evaluation from experimental basic bodices selected by male subjects in the 30's. As a result of sensory evaluation, functional test and clothing pressure test by each type of experimental basic bodices, the 3rd experimental basic bodice was chosen to be a basic bodice type in this research since it showed a high degree in fitness and function, but a low in the clothing pressure test. As a comparison of one item from conventional jacket and sleeve pattern with each somatotype, the type 2(the standard somatotype) indicated a great fitness in both basic bodice type and conventional jacket pattern, whereas the type 1 and the type 3 showed higher fitness and moving function in the basic bodice type. In the making of men's jacket, many corrections were made in the front interscye breadth, back interscye breadth, front and back length, and shoulder line as adapting each body type. Thus, the ease-amount of chest circumference at scye for clothes should be established differently according to the size of chest circumference at scye.

This study investigates the design relation between shoulder line and sleeve line for designing bulky silhouettes as well as examines the trend sensitivity and design difference of each city through a comparison of the four cities collection (Paris, Milan, London, and New York). The results are as follows. In the four major fashion capitals, the rates of all-season coats were higher in 2014/15 F/W than those in the 2013/14 F/W season. At the 2014/15 F/W season, the proportion of the bulky silhouette coat, (including the fur and cape coat) increased and confirmed the bulky silhouette fashion trend. Second, an examining of the proportion of bulky silhouette coats manufactured by leading brands in major cities, indicated that London brands readily followed the trend of bulky silhouette coats when compared to other cities. This trend was also accepted by most brands in New York. Most brands in London and New York are highly compliant with the latest fashion trends. Third, the drop shoulder design was mostly presented in the shoulder pit of the bulky coat. In case of the sleeve, the shape of the jar was kept wide at the elbow line and made narrower toward the beak in most bulky silhouette coats. The importance of shoulder and sleeve design is clearly highlighted in the bulky silhouette coat. Fourth, detail design trends were different according to type of sleeve and shoulder fit. The results show the relationship between shoulder and sleeve design.

소아에서의 슬개골 골절은 성인을 포함한 전체 슬개골 골절의 약 2% 미만에서 발생하고, 모든 소아 골절의 약 1% 정도로 매우 드물게 발생한다. 성장중인 슬개골은 성인에서의 슬개골 골절과는 달리 골연골 골절 또는 견열 골절의 형태로 흔히 발생하며, 그 형태는 주로 소매형 골절로 나타난다. 소아 슬개골의 견열 골절 또는 소매형 골절은 슬개골의 상단부 혹은 하단부에서 발생하나, 대부분 슬개골 하단부가 주를 이루며, 상단부에 생긴 경우는 드물다. 저자들은 16세 소아에서 슬개골 상단부의 소매형 골절 1례를 경험하여 이를 문헌고찰과 함께 보고하는 바이다.

This study was initiated to research on the uniform preference uniform satisfaction and wearing of female workers' uniform of the fiber firms. Data was obtained from 361 female workers of the fiber firms in Chon Buk. And it was analyzed by frequency percent mean duncan's multiple test. The results of this study were as follows; 1) Pocket sleeve and front hem were parts of the damage. The weaving workers were mostly wore upper and under garments but most of there workers were only wore an upper garment on the basic type of uniform The older and married were small in the fitness of uniform the armhole sleeve girth sleeve length and breast girth were unfitted 2) Workers was dissatisfied to the noise and the dust in working environment. Uniform satisfaction of workers were mostly low design color and fabric were the lowest factors of uniform satisfaction. The satisfaction of material were also low the lowest factors were absorptiveness elasticity breathability. Workers wanted the fashion and light colored uniform but they prefered function activity to work and manageability on wearing rather than externals among the uniform preference.

This paper presents the plastic inhomogeneous deformation behavior of bimetal composite rods during the axisymmetric and steady-state extrusion process through a conical die. The rigid-plastic FE model considering frictional contact problem was used to analyze the co-extrusion process with material combinations of Cu/Al. Different cases of initial geometry shape for composite material were simulated under different conditions of co-extrusion process, which includes the interference and frictional conditions. From the simulation results, the sleeve cladding rate at the core/sleeve interface was recorded as a distribution of diameter ratio and interference conditions, which will be useful for the investigations of the bonding process during co-extrusion process. In addition, the results of the co-extrusion, connected with the results of the variations of diameter rate and average contact pressure, demonstrate a good agreement and present the possibility of describing the parameters of the plastic zones in non-uniform deformation of these type of composite materials.

In diesel engines, it is inevitable that the torsional vibration is produced by the fluctuation of engine torque. Therefore, it is necessary to establish preventive measures to diminish the torsional vibration. The sleeve spring type damper is one of the preventive measures for reducing the torsional vibration. In this study, 2-roll bending process was proposed to manufacture sleeve spring; The program to calculate the initial radius including springback effect was developed and the FEA method to analyze elasto-plastic problem was verified through analysis of 90 degree bending process. The elasto-plastic analysis of 2-roll bending process was carried out by the FEA method verified to set a new criterion, and the new process design parameter(contact angle) in the 2-roll bending process was proposed.

Sports climbing requires more maximum body motion range than any other sport. This study examined what element affects the actions of sports climbers and suggest an ideal pattern archetype to maximize function based on motion. The theoretical background included abstracted elements influencing clothing design by researching the body type of sports climbers and the motion of sports climbing. Along with the characteristic of climbing wear, this study also conducted a comparative analysis of sleeve patterns for sports climbing wear and general sports jackets, abstracting comparative parts that influence sports climbing wear design. To develop the final research archetype, research was done on 107 sports climbers in their 20s-30s that selected the top 3 brands and collected patterns as well. A research archetype was selected based on 3-D virtual clothing and developed into 4 different patterns with different sleeve cap heights. Appearance evaluation and a motion functionality evaluation were then conducted in order to select a final research archetype adequate for sports climbing based on evaluation findings. In addition, this study identified aesthetical problems of the final research archetype produced based on functionality that could suggest an archetype for a climbing jacket that could be visually satisfying through appearance evaluations and motion functionality evaluations.

The main purpose of this study was to evaluate the endurance against Al alloy melts and wear resistance of an in-situ synthesized titanium matrix composite (TMC) sleeve for aluminum alloy die-casting. The conventional die-casting shot sleeve material was STD61 tool steel. TMCs have great thermal stability, wear and oxidation resistance. The in-situ reaction between Ti and $B_4C$ leads to two kinds of thermodynamically stable reinforcements, such as TiBw and TiCp. To evaluate the feasibility of the application to a TMCs diecasting shot sleeve, the interfacial reaction behavior was examined between Al alloys melts with TMCs and STD61 tool steel. The pin-on-disk type dry sliding wear test was also investigated for TMCs and STD61 tool steel.
