Since Sirimavo Bandarinaike became the first female prime minister in 1960, women all over the world has been trying to break the highest glass ceiling. In a place where men had been dominating throughout history, women political leaders had to find a way to look the part by wearing power suits. Feminity was out of the question until the digital era of 21st century started. The world has evolved into a place where feminity could be strength instead of weakness. Now women political leaders are showing body curves, cleavage, using vivid and pastel colors, soft fabrics, elaborate details, accessories, long and curly hair. The padded shoulders of dark coloured power suits were replaced by soft colorful flowing feminine suits. Yulia Tymoshenko of Ukraine is the best example of 21st century woman political leader using feminity in her fashion style while enacting her role. When she first started politics in 1990's, she wore dark colored power suits like all other women political leaders did with short dark hair. As time passed her suits became more feminine with light colors and elaborate details. She has changed her hair into a neat braid, based on a traditional Ukrainian hair style. She used orange color for the Orange Revolution and white for pure image. Yulia Tymoshenko's fashion style as a way of role enactment showed professionalism, feminity, integrity, and ethnicity.

Effects of injector position and momentum flux ratio on a vertical jet in a cross flow field were studied qualitatively and shown by using air and water. The experiment was carried out by fixing the momentum flux ratio and varying the position of the injector hole. Conversely, the injector hole position was fixed and the momentum flux ratio was varied. Image visualization was performed by a Shadowgraph technique using a high speed camera. The visualized images were compared for finding differences in spraying through Density Gradient Magnitude Image. It is observed that as the x/d of the apparatus increased the jet break up height decreases and the spray angle also decreases. When x/d is 0, the spray reaches the floor and ceiling at any momentum flux ratio.

Sound insulation performance of a unit cabin mock-up is studied, where two identical rooms simulating cruise ship cabin are installed. STL (Sound Transmission Loss) measurement in the mock-up shows that STL of the partition between rooms is degraded by imperfect door ceiling and gap between wall and floor. It is also observed that gap around lighting and electrical outlet slightly affect the STL in high frequency ranges, since lighting and electrical outlet are supported by mineral wool in the back side due to fire-resistance requirement. Even after all possible gaps are sealed, STL of the partition is found to be lower than that measured in the laboratory by 9 dB. Measurement of SBN (Structure-Borne Noise) reveals that flanking transmission of SBN along the steel deck floor can severely deteriorate STL of the partition. Statistical energy analysis (SEA) of the mock-up confirms importance of the floor SBN control, in which increasing damping is essential to ensure high STL.

Objective: This study tried to examine the muscle activity of the neck and trunk according to head posture changes during use of laptops. Design: Cross-sectional study. Methods: This study included nineteen young men and women. All subjects maintained each posture while practice typing on laptops for ten minutes with a 5-minute break between each posture. For the neutral head posture, the subjects practiced typing while pulling their chins down towards the Adam's apple and were able to look at their knees while having their external auditory meatus, acromion, and greater trochanter vertical to the ground. For the natural head posture, they practiced typing while balancing their posture between extension and flexion of the cervical vertebrae by themselves without any guidelines. While a forward head posture was created by having their heads face the front horizontal to the rope hanging from the ceiling, they practiced typing with their external auditory meatus located in the place which was 5 cm in front of the vertical plane. The subjects used general word process but practiced typing with accuracy and high speed. Muscle activities were randomly measured using surface electromyography according to each postures. Results: The research result had found that muscle activity with the natural head posture was more significantly reduced than that of the forward head posture in the sternocleidomastoid muscle, upper trapezius, cervical vertebral spinae, and thoracic vertebrae spinae muscles (p<0.05) and that the neutral head posture was more significantly reduced than that of forward head posture in the upper trapezius, cervical vertebral spinae, and thoracic vertebrae spinae muscle activity (p<0.05) with significant increases in lumbar spinae muscle activity (p<0.05). Also, muscle activity with the neutral head posture significantly increased more in the sternocleidomastoid muscle and lumbar spinae than that of the natural posture (p<0.05). Conclusions: Our study results suggest that in order to prevent musculoskeletal pain, the neutral head posture with use of laptops is effective in reducing load to the shoulders and vitalizing the postural muscles.

In the case of interior fire in an apartment building, contamination of vestibule area by fire smoke before air fan operating when fire doors are open makes the evacuation of people very difficult. In order to investigate the effect of heat release rate (HRR) and interior opening on fire flow velocity, numerical simulations using Fire Dynamics Simulator were carried out. In simulations, actual dimensions and configuration of an apartment building were considered and interior leakage and HRR were varied. From simulation results, it was found that fire flow velocity distribution is significantly influenced by HRR and interior opening resulting in the change of the location of a neutral plane. Also, it is shown that there is a larger difference of the fire flow velocity between upper and lower part of the fire door when the neutral plane becomes closer to the ceiling.

The aim of this study was to investigate the wearing acceptability of chemical protective clothing during fires and to provide basic data for the safety of firefighters. The results of the study were as follows: Wearer acceptabilities of chemical protective clothing under static movement (e.g., looking at the ceiling with maximum head bending, wrapping one's arms around oneself, sitting obliquely on the floor, and maintaining a crouching position) were 21.7%-47.8% lower than those of general uniforms. When wearing chemical protective suits, the acceptability under static movement was statistically low (p < .001). Wearer acceptabilities of chemical protective clothing under dynamic movement (e.g., running, lifting a heavy object (20 kg) up to the waist, lifting and moving a heavy object (20 kg) by 1 m, lifting a stretcher and walking forward, and lifting a stretcher and walking backward) were 19.2%-47.8% lower than those of general uniforms. When wearing chemical protective suits, the acceptability under dynamic movement was also statistically low (p < .001).

The accurate prediction of fire detector activation time is required to ensure the reliability of fire modeling during the safety assessment of performance-based fire safety design. The main objective of this study is to determine the activation temperature and the response time index (RTI) of a fixed heat detector, which are the main input factors of a fixed-temperature heat detector applied to the fire dynamics simulator (FDS), a typical fire model. Therefore, a fire detector evaluator, which is a fire detector experimental apparatus, was applied, and 10 types of domestic fixed-temperature heat detectors were selected through a product recognition survey. It was found that there were significant differences in the activation temperature and RTI among the detectors. Additionally, the detector activation time of the FDS with the measured DB can be predicted more accurately. Finally, the DB of the activation temperature and RTI of the fixed-temperature heat detectors with reliability was provided.

Cave on the Moon is considered as the most appropriate place for human to live during the frontier lunar exploration. While the lava flows, the outer crust gets cooled and solidified. Then, the empty space is remained inside after lava flow stops. Such empty space is called the lava caves. Those lava tubes on the Earth are formed mostly by volcanic activity. However, the lava tubes on satellite like Moon and planet like Mars without volcanic activity are mostly formed by the lava flow inside of the crater made by large meteorite impact. Some part of lava tube with collapsed ceiling appears as the entrance of the cave. Such area looks like a deep crater so called a pit crater. Four large pit craters with diameter of > 60 m and depth of > 40 m are found without difficulty from Kaguya and LRO mission image archives. However, those are too deep to use as easily accessible human frontier base. Therefore, now we are going to identify some smaller lunar caves with accessible entrances using LRO camera images of 0.5 m/pixel resolution. Earth's lava caves and their entrances are well photographed by surface and aerial camera in immense volume. Thus, if the image data are sorted and archived well, those images can be used in comparison with the less distinct lunar cave and entrance images due to its smaller size. Then, we can identify the regions on the Moon where there exist caves with accessible entrances. The database will be also useful in modeling geomorphology for lunar and Martian caves for future artificial intelligence investigation of the caves in any size.

We study, in this paper, on the decorative design of the Treasure-architectural form for the Silla Buddhist reliquary and this research went through the observation on the Buddhist Reliquaries of the Song-Lim-Sa, the Eastern-Western three floor pagodas in the Kam-Eun-Sa, the three floor pagodas in the Bul-Guk-Sa and the reportedly discovered Nam-Won. The Buddhist reliquaries of these 5 Reliquaries, when compared with those of China and Japan in the same period, they worshiped the Buddhist reliquary as a Buddhist God itself and put them as a part of the architectural decoration, being installed in the construction forms. In the form and the composition of the architecture, we can see those having been designed with very detailed and brightly decorated form. The Buddhist reliquaries in the Song-Lim-Sa and Kam-Eun-Sa, the most important ones in this research, were in a royal palace shape having completely the altar part, interior space part, and the ceiling part, which inform us the whole structure of the architecture in details. In particular, for the case of Kam-Eun-Sa, the columns in the shape of bamboo trees, the expression of the gates, the terrace of double parts formed of word-shape Man, and the statue of a general with superhuman ability in the shrine explain us the description of the Gyun-Bo-Tap-Pum of Lotus Sutra. After all these researches, we conclude that the Buddhist reliquaries in form of the Treasure-architecture represented the architectural style of the same period as a form of industrial arts and we can see that they tried to use all of their highly skilled and talented methods to describe the Buddhist Pure Land.

The purpose of this research is to analyze the methods of the decorations using module plants in interior spaces. This research produced 18 types of the module plant decoration: considering the classifications of module plants(soil, hydroculture, moss), directions of module plants (up, side, down), assembling ways of module plants (horizontal, vertical). Applying these 18 types to the interior space decoration (floor stand, wall attach, ceiling hanging), 54 types were classified. After that, 150 cases of the decoration using module plants in interior spaces were collected and analyzed. In result, the cases were belong to 25 types of 54 types. The important types were the types to be able to decorate wide area of walls or ceilings without occupying floor area: SOIL-UP-VERTICAL, HYDROCULTURE-UP-VERTICAL, MOSS-SIDE-VERTICAL. These types were the decorations with function of bio-filter for air cleaning. Special types were SOIL-SIDE-HORIZONTAL, SOIL-SIDE-VERTICAL with soil developed not to pour and SOIL-DOWN-HORIZONTAL, SOIL-DOWN-VERTICAL with lucks not to pour soil. Plants will be used widely in interior design because of the awareness of eco-friendly design. The strength that module plants are portable, changable, able to exchange parts helps users to maintain plants in interior spaces. For designers, module plants are flexible materials in order to make variety of forms to adjust to interior spaces. The results of this research about methods of the decorations using module plants in interior spaces are useful to designers who want to design interior spaces eco-friendly and user-friendly.
