The Fourth Industrial Revolution has increased studies on observing the cross section by overlapping the clothing worn using 3D human body data. However, there is a lack of studies on the effect of pressure clothing that contracts the shape of the human body. Therefore, this study objectively evaluated the shaping functionality of body shapers using 3D scan and 3D data. Two types of commercial body shapers were selected for this study. The nude body and body wearing body shapers were then scanned. A 3D program evaluated the shaping functionality by overlapping the nude state with the body wearing body shaper A and B respectively. As a result, it was found that the effect of body shapers could be adequately observed according to body parts. The smaller body shaper was shown to have superior shaping capability with the abdomen more affected. Analysis of the horizontal cross section indicated that the waist circumference decreased by 6 cm when wearing body shaper A and decreased by 12cm when wearing body shaper B. The volume of the waist part decreased by 8.6% when wearing body shaper A and by 20.4% when wearing body shaper B. Therefore, it is more effective to compare the objective shaping functionality by body parts using the overlapped 3D scanned data rather than using exterior evaluation or length measurement when wearing clothing that contracts the body shape.

Snowboarder accidents at ski resorts are increasing; therefore, it is essential to wear protective wrist, hip and knee protectors when snowboarding. However, most studies focus on the improvement of gear or expansion of safety facilities with few studies on protectors that directly safeguard the body from accidents caused by tumbling. Protectors currently on the market do not properly consider the needs of the users. Therefore, this study investigates the reality of usage and satisfaction rate of those that use snowboarding protectors along with factors deemed important upon wearing them to provide the grounds for the development of comfortable protectors. Subjects were 1,058 adults in their 20s to 40s. First, a survey was conducted regarding demographic traits as well as the wearing and purchasing of protectors. Second, 325 people that purchased and wore protectors were investigated in regards to the wearing satisfaction rate of current commercial protectors. The results showed that 86% of the 1,058 subjects wore protectors; knee protectors (72%), hip protectors (57%) and wrist protectors (38%). Important factors upon purchasing and wearing satisfaction were studied according to demographic traits, snowboarding experience, and number of snowboard rides for one season. As a result, the damage rate increased along with the number of snowboard rides for one season. Important factors considered when purchasing varied significantly according to sex, age, snowboarding experience, and favored slopes. The results of this study will help in the design of comfortable protectors for snowboarders.

The study was designed to investigate the antibacterial effect of Helicobacter pylori against 32 medicinal plants commonly used as health foods. The medicinal plants used in this study were 32 kinds of medicinal plant extracts using the disk diffusion method for H. pylori activity, which can be eaten every day by everyone. Amoxicillin sodium (150 mg / ml, Ildong Pharmaceutical) and Metronidazole 50 mg / ml) was used as a control group. We measured the area of the transparent area and evaluated that the larger the area, the more effective it is for H. pylori. As a result of this study, the clear zone of inhibition was highest at $372.90mm^2$, second was $358.30mm^2$, and Chungho was $348.32mm^2$. The positive control group, Metronidazole (50 mg / ml CJ), was $503,29mm^2$. In the future, the development of antimicrobial materials of various medicinal plants is expected to be effective for the inhibition of H. pylori.

In this paper, we designed a new antireflective film to improve the optical efficiency of organic light-emitting diode displays (OLEDs). The reflection characteristics in the normal and side viewing directions of OLEDs with the antireflective film were calculated, depending on the degree of polarization and transmittance of the currently used polarizer when used in the antireflective film of an OLED. The results showed that when the polarization degree of the commercial polarizer (99.990~99.995%) is lowered to 99.900%, the average reflectance of the antireflective film is increased by about 0.1% (2.5% in terms of rate of increase) which is difficult to notice with the human eye, while the transmittance is increased by 1.63~3.34% (4.2~8.2% in terms of rate of increase). This study provides an optimal design for high-light-efficiency OLEDs with good antireflection properties.

Ready-made products produced in the industrialized consumer society after the 20th century have been adopted by artists as a new material called "Found object," and are reinterpreted in a broad sense in their works. The method of giving new meaning using this creates a new paradigm that is expanded conceptually as well as expression style. After Pablo Picasso's in 1912, when the Found object was used for the first time in contemporary art, we examine the development of objects through Dadaism, Surrealism, and Pop Art, and the expression of Found objects in the late 20th century. In this study, the artists and their work are analyzed by dividing it into three types: 'Unprocessed objects', 'Transformed objects', and 'Tenant objects', depending on how the Found object is mixed in works. Through this study, I pay attention to the fact that a work incorporating a Found object not only develops the object materially, but also allows the practice of free concept art to escape from the traditional norms of art.

Various types of clothing are being developed to boost thermal comfort during cold winters along with research on change of body temperature when heating is applied. There is a noticeable behavioral difference by gender when using heating panels in a cold environment; however, research on women has been insufficient. This study find a temperature range that provides sustainable thermal comfort in a low temperature environment by observing temperature and change of temperature when subjects are classified according to physical activities or cold sensitivities. For the study results, 8 women in their 20s were subjected to experiment in a low temperature environment for 75 minutes (sitting position: 30 min., running: 15 min., and sitting position: 30 min.). Subjects were asked to turn on/off the heating panel freely to analyze the range of comfortable temperature and clothing microclimate; in addition, skin temperature and heating panel temperature were measured and analyzed at 9 points. As a result, temperature at which subjects turn on and off the heating panel indicated a statistically meaningful difference between the cold sensitivity group depending on exercise or non-exercise. The range of comfortable abdomen temperature was wider than the lower back and was significantly reduced when the subject was running. The range of comfortable temperature was also largest for the heating panel temperature, microclimate, and skin temperature in suggesting that adequate adjustment will be required depending on the surrounding environment or movement of the wearer.

This study aimed to develop a new Hanbok Jeogori prototype based on design extracted through a preference survey on new Hanbok Jeogori. This study was conducted based on K-patterns selected as excellent patterns in prior research and utilized the SPSS 27.0 program for analysis of appearance evaluation. As a result of the first appearance evaluation and garment pressure evaluation, the shoulder area was required to be modified, so the shoulder end point was moved within 1cm to rearrange the armhole line. Modification of sleeve length and circumference was also required, reducing sleeve length by 1.5cm and sleeve circumference by 0.5cm at both ends. As a result of the second evaluation, the length of Jeogori, hem circumference, and sleeve length were required, reducing the length of the front and back Jeogori by 1 cm and reducing the sleeve length by 1cm. The hem circumference was reduced by 0.2cm each in the princess line, which was highly evaluated in the final evaluation. In future research, it is thought that pattern studies by material, length, and age should be conducted and corrections should be derived through actual wear experiments.
