This study investigated the problems of Korean female combat uniforms and collected primary data for developing new combat uniforms with improved functionality. We analyzed fit and motion suitability by administering a questionnaire evaluating the current uniforms to 20 Korean female soldiers. The evaluation of fit suitability found that satisfaction with the combat uniforms was generally high. However, short sleeve length, large wrist circumference, small hip circumference, large ankle circumference, and low crotch height were discomfort factors. In the evaluation of motion suitability, dissatisfaction was found with the sleeve circumference, elbow circumference, armhole circumference, knee crease and crotch height, and back waist height during motion. Therefore, it is necessary to establish a more segmented size system that suits the physique of current female soldiers and to devise appropriate solutions for improving motion suitability. This study is meaningful for its evaluation of the current combat uniform of female soldiers, and it is expected to serve as a reference for the future development of military combat uniforms for this group.

This study investigates the problems of fitness and motion suitability for Korean male military winter jackets (inner and outer) and provides data for new pattern development. We analyzed fitness and motion suitability by a questionnaire survey with 140 Korean male soldiers and a wearing evaluation with 7 subjects of central army male size. A survey of male soldiers indicated that the fitness and motion suitability satisfaction was over 3.0 (Likert scale) for both inner and outer jackets. There were opinions that the sleeve length was short for the inner jacket and the waist girth and hem girth was slightly large for the outer jacket. In the wearing evaluation results with subjects of central army male size, fitness of total length, sleeve length and collar height showed a score lower than 3.0 for the inner jacket and collar height on the outer jacket. The motion suitability result showed a low score (1.0-2.0) in an arm raising motion for the inner jacket and 2.0-3.0 at neck motion in the outer jacket. In conclusion, there is more dissatisfaction in inner jackets than outer jackets. For the inner jacket, sleeve is short, sleeve hem is narrow, collar height is a little high and the sleeve creeps up during arm motion. The waist girth and hem girth was slightly large and collar height was a little high for the outer jacket.

This study developed an ergonomic Korean female military winter jacket and (inner and outer) pattern in in order to increase dimension and operational suitability for military missions. First we developed the 1st development pattern and sample jackets with improved dimensions and operational suitability based on a previous investigation of fitness and motion suitability of Korean female military winter jackets (inner and outer) and motion suitability by a wearing test. The evaluation result of fitness for the 1st development pattern were over 4.0 (5.0 Likert scale) for both the inner and outer jacket, a positive result and the result of motion suitability were over 3.5 in both the inner and outer jacket except for the neck front part by collar height. However, we did not modify the collar height because decreases in warmth and military regulations. We also evaluated appearance by experts that showed good results in both the inner and outer jacket. Finally, we developed a final pattern based on evaluation results and military regulations. Existing military uniform research was conducted mainly on male soldiers. Beginning with this study, we expect to expand research on the development of military uniform patterns suitable for a female soldier body type.

For the structural firefighting protective clothing, it can show a synergy effect when it satisfies smart fabric to block off a harmful environmental element and ergonomics design that apply range of motion of human body and appropriate size system. There are various standards about the structural firefighting protective clothing, but it's difficult to find a rule about movement suitability because the performance of the material holds a lot of the rules. Therefore, the purpose of this study is to propose a scheme to evaluate the current structural firefighting protective clothing and to improve movement suitability by research on the actual condition. For this, the survey about wearer acceptability scale on design and size and about improvement requirements was executed gathering firefighters' opinion. Questionnaire was composed with 23 items about satisfaction on current structural firefighting protective clothing, body suitability, movement suitability, improvement requirement and subjective information. As a results, Korean firefighters demand ergonomics design of structural firefighting protective clothing which to minimize restriction of body movement and to maximize body suitability.

In this study, the fit of commercial sports bras was analyzed according to various design variations, focusing on the shape of the shoulder strap, which is known to cause great discomfort in wearing sports bras. Experimental clothes were set to four commercially available sports bras with different shoulder strap shapes. The results showed that, in "size suitability," the overall satisfaction with experimental clothing B, of which the shoulder strap can be adjusted, was the highest, especially for "underbust circ. fit," "bust circ. Fit," and "shoulder strap length." In the "Shape suitability" and "Wearability" sections, experimental clothing B also showed the highest satisfaction and the shoulder strap adjustment device did not negatively affect wearing satisfaction. In the question on "side wings rolled up," experimental clothing A also received a relatively good score, which is due to its long front length. In the "Compression of the front center" section, the responses for experimental clothing A and B were "appropriate" and for C and D, they were "pressurized." In "motion suitability" as well, satisfaction with experimental clothing B was the highest, followed by experimental clothes A, C, and D. In the "body shape correction" section, clothing B elicited the highest satisfaction, followed by experimental clothes A, C, and D, in that order. Overall, it is recommended that shoulder straps be applied with adjustable straps for the comfort of the shoulder area while wearing sports bras.

This study was to develop an ergonomic Korean male military winter jackets (inner and outer) pattern. First, we developed a prototype pattern and sample jackets based on a previous investigation for fitness and motion suitability of Korean male military winter jackets and evaluated fitness and motion suitability by a wearing test. The evaluation results were positive with an over 3.0 (5.0 Likert scale) for both the inner and outer jacket. However, a relatively low score was shown in the sleeve length and collar front height at the inner jacket and shown in hem circumference, neck circumference, elbow and front neck at the outer jacket. Next, we developed the secondary pattern and sample jacket reflecting the prototype evaluation result and executed expert evaluation. The result showed that the ease amount was appropriate (except for the collar back height) and the appearance was good. Finally, we developed a final pattern that showed good results after evaluation at a Korean military army base.

The purpose of this thesis is to conduct research on the degree of satisfaction (for both wearing and functioning) of cycle wear; to present the basic data to develop cycle wears which can lesson the trouble for human body and have an excellent feeling in wearing. To inquire the degree of satisfaction, the method of questionnaire was used for 100 peoples consisted of male cycling players. As the result of the satisfaction degree in wearing, it can be certain that the users are satisfied overall and yet they express the lowest satisfaction at material among material, design, color and function. When it comes to unsatisfactory factors of wearing cycle wear, the most unsatisfactory one is the poor function of clothing on the whole. As the result of the site suitability of cycle wear, we can find the problems on the girth of neck and armhole of the upper garment, and on the part from waist to hip length and the girth from thigh through knee to calf of lower garment. As the result of the motion suitability of cycle wears, we can acknowledge that there are problems on the part of neck, armpit, and abdomen of the upper garment rather than the lower one.

This paper examines the suitability of using the Computational Fluid Dynamics (CFD) tools, ANSYS-CFX, as an initial analysis tool for predicting the drag and propulsion performance (thrust and torque) of a concept underwater vehicle design. In order to select an appropriate thruster that will achieve the required speed of the Underwater Disk Robot (UDR), the ANSYS-CFX tools were used to predict the drag force of the UDR. Vertical Planar Motion Mechanism (VPMM) test simulations (i.e. pure heaving and pure pitching motion) by CFD motion analysis were carried out with the CFD software. The CFD results reveal the distribution of hydrodynamic values (velocity, pressure, etc.) of the UDR for these motion studies. Finally, CFD bollard pull test simulations were performed and compared with the experimental bollard pull test results conducted in a model basin. The experimental results confirm the suitability of using the ANSYS-CFX tools for predicting the behavior of concept vehicles early on in their design process.

This study used a preliminary survey to help develop an ergonomic flight jacket that is suitable for the working environment and mission performance. The results are as follows. The ergonomic sleeve pattern was designed with a forward 165° incline that considers a shoulder joint direction suitable for the motion; in addition, a closely design opening provided warmth and safety from fire. As a result of the dimensional suitability, pilots evaluated that sleeve length and total length of the developed flight jacket were a little long (p<.01), while flight engineers and crew evaluated that those of the developed flight jacket were appropriate (p<.01). Pilots evaluated that chest circumference and waist circumference were large (p<.05), while flight engineers and crews evaluated that those of the developed flight jacket were appropriate. The evaluation of the motion suitability indicated that pilots, flight engineers and crew found the developed flight jacket more comfortable than the current flight jacket (p<.05, p<.01, p<.001). The evaluation of the usability of pockets and penholders indicated that pilots, flight engineers and crew found the developed jacket easier to use (p<.01). The flight engineers and crew evaluated that the appearance of the developed flight jacket was better than the current flight jacket (p<.05). The results of this study show that the difference of environment and mission performance has a significant influence on evaluation; therefore, it is necessary to develop separate military uniforms that included a winter flight jacket to reflect the needs of each group.
