The nursery active-wear uniform designs of Internet shopping malls are simple and similar; however, the latest children's wear trends (mostly composed of training jumpers and pants) do not reflect these qualities. Children's folklore plays (widely used in child education) have an instructive value for the emotional and intellectual development of a child. Nursery active-wear uniform designs applied to children's folklore's plays could be positive for the emotional development and specialized cultural education of children. We designed three nursery active-wear uniforms with three different design concepts (casual, semi-formal and sporty) regardless of sex. The main color of the three nursery active-wear uniforms was yellow. We used three different chroma and values of yellow through three design concepts: Design I of a nursery active-wear uniform (a training suit style with a good activity), Design II of a nursery active-wear uniform (a semi suit style), and Design III of a nursery active-wear uniform (a sportswear style that reflected a sport wear trend). We expressed children's folklore plays in the pattern of a nursery active-wear uniform. The pattern was characterized as a pair of bears flying kites. This pattern was utilized in three nursery active-wear uniforms with the logo and name of the nursery. We modified the designs of active-wear nursery uniforms based on an evaluation of 33 special panels. We made three nursery active-wear uniforms for five-year olds.

This study intends to provide sources which enable students to satisfy uniform design as I surveyed preferable uniform design and degree of satisfaction of uniform design to students. The subjects were gathered into 91 middle-high schools and surveys were done among 400 school girls. The results are as follows; 1)The survey of uniform which students wear. For jacket, tailored collar which is single breasted is most common and for blouse, puff sleeve, soutein collar, shirt collar is common. For skirt, lastly, they usually wear side pleats skirt. 2) Thoughts of uniform students preferred uniform to casual. The merit of wearing uniform can represent themselves as the ‘students’on the other hand, the demerit is shown that uniform is inconvenient enough to move. 3)Preference of uniform design. Students prefer tailored jacket, shirt blouse, flare skirt. Basing on these results above, I’d like to suggest something about uniform. The demerit of wearing uniform lies in inconvenience. It would weaken the degree of satisfaction of uniform and have a negative influence on students in physical and mental side. So we have to find out the concrete problems, at the same time, develop measurable study which fit for body. Adolescence is period of developing and establishing self. So they really need rather creative educational atmosphere than stereo typed-control. Reflecting this opinion, Clothing habits can play an important role and in future it is desirable to have students wear not uniform but casual.

The investigation of the disc cutter wear prediction has an important guiding role in TBM equipment selection, project planning, and cost forecasting, especially when tunneling in a long-distance rock formations with high strength and high abrasivity. In this study, a comprehensive database of disc cutter wear data, geological properties, and tunneling parameters is obtained from a 1326 m excavated metro tunnel project in leptynite in Shenzhen, China. The failure forms and wear consumption of disc cutters on site are analyzed with emphasis. The results showed that 81% of disc cutters fail due to uniform wear, and other cutters are replaced owing to abnormal wear, especially flat wear of the cutter rings. In addition, it is found that there is a reasonable direct proportional relationship between the uniform wear rate (WR) and the installation radius (R), and the coefficient depends on geological characteristics and tunneling parameters. Thus, a preliminary prediction formula of the uniform wear rate, based on the installation radius of the cutterhead, was established. The correlation between some important geological properties (K_V and UCS) along with some tunneling parameters (F_n and p) and wear rate was discussed using regression analysis methods, and several prediction models for uniform wear rate were developed. Compared with a single variable, the multivariable model shows better prediction ability, and 89% of WR can be accurately estimated. The prediction model has reliability and provides a practical tool for wear prediction of disc cutter under similar hard rock projects with similar geological conditions.

This study has the purpose to find basic materials for development of kindergarten's uniform and suggest the improvement of its design based on the survey results from Suncheon area in Jeollanam-do of Korea. Such study methods were conducted as literature review, survey with direct visit, interview, and photographing of dresses regarding the kindergarten uniform. The following are research results. First, kindergarten teachers presented a positive opinion about the necessity for children to wear the uniform. In selection of design, they regarded the activity as most important factor. Kindergartens applying active wear compatible as townwear also accounted for 57.1%, which is more than half. Second, the formal wear, in the winter season was found to consist with jacket or knit cardigan, knit vest, shirts, skirts or pants, and necktie. For color, most of them are in dark tone, which need to be brighter. For pattern, they are in plain color, which needs to have various patterns. As to the cloth material, such problems should be improved as warmth retentivity in consideration of seasonal nature, moisture retentivity, breathability, color retentivity when washing, and harmless to human body. Third, active wear is mostly the casual sportswear type. But it has no characteristic unique to kindergarten in design and needs to be altered for differentiated design. Especially, it is simply divided into winter wear and summer wear in kind. Therefore, it is required to have differentiation for seasonal characteristic and diversity in number of item and improvement in terms of cloth material.

Currently, a lot of people are aware of their health and well-being, so they are concerned about their healthcare. 'Taekwondo' is one of the popular sports that Korean people are passionate about Taekwondo has also become globalized. The uniform of Taekwondo is gaining importance. Taekwondo involves a lot of movement, hence the pattern should facilitate the movement. In addition Taekwondo uniform pattern should meet the demands of functionality, fit and consumer design preferences. This study aimed to provide the basic data for development of Taekwondo uniform pattern based on design preferences and functionality to wearer satisfaction. The result of this method indicated fit and design details. Also, the length of pants, top, and sleeve was too wide, which has to more fitted for both of genders. For females, the breakpoint was too low, which requires some increase to make females feel more secure. In conclusion, the results of this study indicated that in order to increase 'Takwondo' value, Taekwondo uniform is required to be more fashionable and comfortable to wear, which could influence other sports wear.

The purpose of this study is to examine introduction and establishment of the police uniform during Japan's early Meiji period, in order to get deeper understanding of the introduction of the modern uniform. The research method included a literature review of laws related to police uniform, which were collected and analyzed. The result shows that the uniform stipulated by Keisi-cho Uniform regulation in 1874 included characteristics of Western uniforms that show the rank of the officers using emblems, such as different cap badges and uniform stripes, while maintaining the same form. Later, the modern uniform system came into form with the addition of a national symbol, building system of formal wear, separating uniforms for different classes, and adding additional uniforms. This illustrates the process of introducing and establishing western-style uniform in the East and can serve as a reference for similar studies.

This study analyzed and compared wearer mobility for different types of clothing that also included the potential to develop firefighter station uniforms using range of motion (ROM) and electromyography (EMG). This study focused on a comparison of wearer mobility affected by different materials and shapes of the station uniforms worn under firefighter turnout gear. Japanese standard uniform (UNI), stretch-wear (ST), and compression-wear (CP) were used as station uniforms for the experiment. This study analyzed wearer movements and quantified ROM and EMG. In addition, the subjective evaluation of wearer mobility and comfort were assessed for comparisons. Nine healthy male students participated in the experiment. Wearer mobility was analyzed using ROM and EMG data obtained by measuring five motions; in addition, subjective evaluations were also obtained. As compared with the standard station uniform, ROM increased 6.8 % and 7.2 % due to stretch-wear and compression-wear. The benefits of wearing stretch material or compression material to improve muscle performance (such as reduced percent of maximum voluntary contraction) were not proven. Differences between materials and designs influenced subjective wearer comfort. In particular, the wearing of compression materials was shown best in terms of wearer comfort that may also allow greater wearer mobility.

In recent times the potential application of the high speed steel produced by HIP process for wear resistant and cutting materials are increasing. In this work the microstructure of Anval 30 produced by HIP process was investigated and the effect of WC, TiC addition on microstructure formation and wear properties were studied. After HIP process at 1150 $^{\circ}C$, the original feature of spherical raw powders was not removed and consequently, nonuniform microstructure was formed. However the WC added by simple powder mixture incereased the sinterbility of high speed steel and uniform microstructure formed. The wear characteristics of Anval 30 with carbide addition were tested at RT and $600^{\circ}C$. The uniform microstructure played an more important role in wear resistance as compared with the hardness.

PTFE is generally utilized as the form of composites with adding various fillers. The purpose of this paper lies on clarifying the friction and wear properties of the PTFE coating layer on steel. Especially, the effects of PTFE powder size for coating and surface roughness of the counter material on the properties are investigated. Sliding friction and wear tests are conducted at several sliding speeds by employing two types of PTFE coating layer using different powder sizes. One type of coating layer is composed of uniform fine powder, whereas the other type is made up of mixture powder of different sizes. As results, it is found that PTFE coating layer are effective to improve the wear resistance and to reduce the friction coefficient. It is clear that PTFE coating layers are abrasively removed by asperities of the counter material during sliding contact. However, PTFE coating layer with uniform fine powder shows somewhat better wear resistance than that with mixture powder of different sizes in low sliding speed region. It can be seen that the wear of the coating layer are drastically reduced because wear fragment from counter material are transferred to the coating layer. On the other hand, friction coefficient is shown not to be directly related with PTFE powder size in coating layer.
