This study analyzed the body-type characteristics of 340 old-aged obese women that had been on the rise as a part of efforts to activate the silver clothing industry. The subjects were in the age range of 60-79 and met some obesity requirements, including a Rohrer Index of 1.6 or higher, a BMI of 25 or higher, and a WHR of 0.85 or higher. Old-aged obese women showed increased thickness of the torso with age, which suggests that they revealed the characteristics of regardless of gender. In other words, they became bigger in the waist and abdomen, shorter in height, slimmer in the lower body, and thicker in the torso. There are three types of obesity: Type 1 is lower-body obesity with a higher degree of obesity in the abdomen than the upper body. Type 2 is abdominal obesity with a higher degree of obesity in the upper body than in the lower body. Type 3 is whole-body obesity with balanced obesity of the whole body. As for changes to the types of obesity according to age, those who are in their sixties usually fall into the categories of upper-body and whole-body obesity, and those who are in their seventies are much more concentrated in the categories of abdominal obesity and upper-body obesity with a decreased percentage of whole-body obesity. It is apparent that the percentage of abdominal and upper-body obesity rises with age due to fat accumulation in the abdomen.

The purpose of this study is to understand the characteristics of body types of adult woman under 155cm in height. To do this, direct measurement data showed that only 660 women aged 20~69 years old and under 155cm tall were classified, and their body type characteristics were analyzed. There are 51 body measurement items used in the analysis. The results of the study are as follows: As a result of the comparison of the body size of all adult women and women under 155cm, it was seen that short women were smaller than the all women, and were flattened with a slightly plump and bendless body. Factor analysis was performed to classify the body type of short women. Six factors including body size, body height, shoulder length and width, waist back length, hip length, and shoulder angle were measured. The results of cluster analysis, using factor scores, were classified into three types. Type 1 is taller among short women and slightly slimmer, and is an A-shape. Type 2 has the largest BMI and was the middle stature among short women It is the most obese body type and is an H-shape. Type 3 is short and plump, with a poor hip and is a Y-shape. As a result of crossover analysis, there was a difference in the body type characteristics of each age group. After all, the body type of the short adult women under 155cm was clearly different from those of all adult women, there was also a difference in the body type among short adult women.

This study conducted a questionnaire survey on diet behavior in male and female university students in Cheongju area and examined the behavioral characteristics related to diets such as body type awareness degree, actual weight and height, diet experience, and side effects. The desired average weight of male students was 68.81kg, which was 6.42% less than the current average weight of 73.53kg. The desired weight of female students was 49.15kg, which was 9.95% lower than the current average weight of 54.58kg. There was a significant difference between male and female groups in all questions on diet characteristics (p<0.05, p<0.01, p<0.001). Looking at the result of this study, it is necessary to provide accurate nutrition knowledge and proper education and counseling programs so that university students who desire to have a slimmer body shape that have highly dissatisfied view on their weight can maintain their healthy life through desirable weight management.

Purpose: This study was planned to clarify a negative view of chewing gum due to the concern that continuous gum chewing might cause a change in the gonial angle and make the lower facial appearance look square. Materials and Methods: We had 25 adults (13 males and 12 females, with an average of 27.3 years) chew 6 g of gum (spearmint) evenly with both right and left posterior teeth for one hour per day for three months. We then measured their gonial angle, the inclination of occlusal plane, facial height, bone marrow density, and masticatory force before chewing, 1, 2, and 3 month after chewing to verify its significance statistically. Result: The results showed that the gonial angle increased from $122.7^{\circ}$ to $123.3^{\circ}$ (P>0.05), and thus the jaws became slightly slimmer. There was no change in the occlusal plane inclination and facial height. Meanwhile bone marrow density in the mandibular angle and ascending ramus increased from $0.285g/cm^2$ to $0.290g/cm^2$ (P<0.05), and masticatory force also increased by 0.5 kg on the right side and 0.8 kg on the left side (P<0.05). Conclusion: Continuous chewing of gum gives an appropriate exercise effect to the stomatognathic system. As chewing gum has effect on increase bone marrow density without changing the mandibular angle and facial appearance the claim that jaw bone changes to a square jaw through chewing gum is regarded to be groundless.

The purpose of the study is to figure out the difference in preference of clothes between Korean and Chinese female college students, who share similar ethnic traits despite having different sociocultural backgrounds and environment, and see the differences in their body image and body satisfaction. The questionnaire-based survey for the study was conducted for about a month and a total of 449 copies of the questionnaire were collected for the final research. For the research method, we examined the differences in clothes preference and fit between Korean and Chinese students, and then the corresponding differences in body image and body satisfaction. The result showed significant differences in the categories of skirt length, pants length, upper garment fit, and lower garment fit. Korean students preferred slim fit clothes, while their counterparts preferred natural fits. A comparison of body image between Korean and Chinese female students showed that the Korean students had lower body satisfaction levels, and viewed themselves as fat even though they were slimmer than their counterparts. The conclusion of the analysis was that compared to Korean students the Chinese students pursued a more comfortable and casual style, preferring unique and diverse designs instead of simply following a fashion trend.

People have been getting interested in the Orientalism and it has come up in various areas due to scientific progress. I designed uniforms, which was simple and western, to show its symbolic meanings in the Orientalism. And I have been trying to generalize uniforms with originality and beauty. I have studied the process of the Orientalism and its changes and transitions, concepts and origins in history. And I applied the styles of Korean, Japanese and Chineses costume on it. I also referred to characters of uniforms, which already had images of Korea, Japan and China. Firstly, Korean styles have a contrast in colors by application of Taegeuk. And they gave lines with dark colors in black one-piece dress. This makes people who are wearing looking slimmer. White ramie top looks fresh and Korean traditional tie called Maedeup is set up for button. Secondly, Japanese styles were mainly Kimono style, one piece. They changed into two pieces designed to be active. So, it has emphasized the image of Kimono with Obi at the waist. Thirdly, Chinese styles basically are Chipao style, which has a Chinese collar and a long skirt, which has opening. But they gradually changed into short skirts and more open in the chest. For one of them, they gave lines in the side of chest, sleeves and skirt to be more natural. The costumes have kept their positions as a part of mass society that grows and changes with speed. And oriental uniforms are not just uniforms any longer only for work. It is quite symbolic like a 'second face' as it represents images for their countries and enterprises.

The continuing demand for increasingly slimmer and brighter liquid crystal display (LCD) panels has led to an increased focus on the role of light guide panels (LGPs) or optical films that are used to obtain diffuse, uniform light from the backlight unit (BLU). The most basic process in the production of such BLU components is the micromachining of V-shaped grooves. Thus, given the current trend, micromachining of V-shaped grooves is expected to play increasingly important roles in today's manufacturing technology. LCD BLUs comprise various optical elements such as a LGP, diffuser sheet, prism sheet, and protector sheet with V-shaped grooves. High-aspect-ratio patterns are required to reduce the number of sheets and enhance light efficiency, but there is a limit to the aspect ratio achievable for a given material and cutting tool. Therefore, this study comprised a series of experimental evaluations conducted to determine the machining limit in microcutting V-shaped grooves on electroless nickel plated die materials when using single-crystal diamond tools with point angles of $20^{\circ}-80^{\circ}$. Cutting performance was evaluated at various cutting speeds and depths of cut using different machining methods and machine tools. The experimental results are that V-shaped patterns with angles of $80^{\circ}$ or up can be realized regardless of the machining conditions and equipment. Moreover, the feed rate has little effect on machinability, and it is thought that the fly-cut method is more efficient for shallow patterns.

Recent development of core techniques the IT electronics industry can condense into lightweight and slimmer. In this circumstance, researches for the lightweight materials and subminiature screw have been attracted. In this study, the CFRP was produced by stacking angle to obtain the tensile properties. And Comparing the coated screws and non-coated screws on the specimen, and evaluating the adequacy for the application of CFRP using the result. So The clamping force measured by comparison evaluation. Low screw reverse and Superior torque value at each stacking angle were found the optimum conditions, when Subminiature Screw is applied on smart devices. Both tensile strength and stiffness of $[{\pm}0^{\circ}]_{10}$ is the highest. Followed by $[90^{\circ}/0^{\circ}]_{10}$ is the highest. The largest clamping torque is $[90^{\circ}/0^{\circ}]_{10}$ When Subminiature Screw is applied coating and non-coating to prevent loosening. Based on the above, Subminiature Screw should be applied in smart devices, because $[90^{\circ}/0^{\circ}]_{10}$ meet both tensile properties and clamping force.

As the number of smartphone users grows, number of applications and the expected overall functionality in a smartphone grow simultaneously. With ever-so increasing expectations comes intense competition to squeeze in myriads of functions in a limited space that is only getting 'slimmer' by the year. In order to achieve this, companies often decrease the size of components in smartphones - battery connectors in particular. While they may fit, smaller battery connectors have their disadvantages due to the heat generated by the high current flow in the circuits. In collaborating with Korea's leading battery connector manufacturers, this research presents current issues and design concepts that should be considered when engineers design power connectors based on their electrical and thermal analysis.
