Plasma nitriding is a surface treatment process which is increasingly used to improve wear, fatigue and corrosion resistance of industrial parts. Active screen plasma nitriding (ASPN) has both the advantages of the classic cold wall and the hot wall conventional dc plasma nitriding (DCPN) method and the parts to be nitrided are no longer directly exposed to the plasma. In this study, AS plasma nitriding has been used to nitride the UNS S31803 duplex stainless steel, AISI 304 and AISI 316 austenitic stainless steel, and AISI 420 martensitic stainless steel. Treated specimenswere characterized by means of microstructural analysis, microhardness measurements and electrochemical tests in NaCl aerated solutions. Hardness of the nitride cases of AISI 420 stainless steel by Knoop test can get up to 1300 HK0.1. From polarization tests, the corrosion current densities of AISI 420 and UNS S31803specimens ASPN at $420^{\circ}C$ were generally lower than those of their untreated substrates. The corrosion resistance of UNS S31803 duplex stainless steel can be enhanced by plasma nitriding at $420^{\circ}C$ Cowing to the formation of the S-phase.

The objectives of this study the effects of fabric noise from active wear on electrodiagnosis(EMG), to examine the effects on subjective sensation, and to relate the EMG results and the subjective sensation.. Five nylon water repellent taffeta fabrics were rubbed each other and the fabric noise were recorded. EMG was done from 10 female university students and electrodes were attached on each participant's upper arm and lower am. The subjective sensation was measured by FMME(Free Modulus Magnitude Estimation). The EMG values from upper arm showed higher voltage than those from lower arm, and the differences between values with fabric sound and without were larger at upper arm than those at lower am. EMG decreased when fabric sound was evaluated soft and pleasant, however It increased in proportion as fabric sound was evaluated loud and sharp. The predicted models for subjective sensation using physical sound properties and EMG results were well explained except roughness. Pleasantness was well predicted by EMG at upper am and EMG at lower arm, as the result, it was explained that the lower the EMG, the more pleasant the participant.

Background: This study was designed to analyze Repetitive dorsiflexion exercises in ankles have effects on the active range of flexion and extension motion through lumbar, cervical spine and ankle, wrist joints. Methods: 30 female college students in their twenties who frequently wear high heels participated the number of the experimental group was 15 persons and the number of the control group was 15 persons. They did exercise at the physical therapy room in M college, from the 8th of March to the 11th of April 2007. The experimental group had used the model of dorsiflexion repetitive exercise three times per week, for 4 weeks, but the control group did not exercise at all. In the sagittal plane active ROM of the these spine and joints were measured before and after the experiment using a digital goniometer. The results of two groups were compared and analyzed using paired T-test. Results: The active range of flexion and extension motion of the vertebra(especially lumbar flexion) and distal joints were significantly different in exercise group(p<.05). Conclusion: The model of repetitive dorsiflexion exercise of the ankle joint had positive effects on improving the active range of flexion and extension motion of the lumbar vertebra and distal joints of limbs. The results suggest that the repetitive dorsiflexion exercise is useful and also effective therapy for improving motion in women usually wearing high-heel.

The purpose of this study is reviewing and researching the symbolic meaning and classifying the types of the style of the Costume in classical novel 'Shimchungjun' focusing on the woman's costume through the antique records and tombs bequests. Titled ladies for royal family put on 'Wooimkyoryong' and 'Sungun' as a petticoat when the ladies of Song period rode on horses. The underskirt played a part to swell a skirt for ladies. 'Bakjueui' and 'Hwangsangi' were ordinary clothes ranging from ladies of loyal family to women. The red color was limited to royal family. The ordinary clothes of women were white ramie clothes commonly and floral patterned clothes were prohibited to the ordinary clothes for women. 'Ko', a breast-tie (breast ribbon) of a Korean coat, was made of silk and women wear as an outer garment. The common people will wear 'Ko' of white ramie clothes which was very active items. The ladies of royal family and women put on shoes made of white ramie clothes, but the full dress of queen wore blue boots made of leather. The noble women wore 'Suk'(boots) made of deer skin and common people wore straw shoes regardless of gender and age. Sometimes they wore 'Woopihye' made of cowhide. In the first of Koryo era, the styles of dress were consisted of 'Monso', 'Eui', 'Po', 'Dae', 'Koh', 'Sang', 'Sungkun' and 'Kangnang'. The structure of costume for women made little difference and there was a great difference with decoration.

The purpose of this study is to supply available data for men's fashion design planning by analyzing the trend and design tendency of the preppy look in the domestic men's collection. In the men's collection of Seoul fashion week from 2011 S/S to 2015 S/S, 494 photos judged to be the preppy look by three design specialists were chosen in Seoul fashion week and style.com's web-site. Design analyses were compiled based on year, season, brands, item, color, material, and silhouette. The preppy look was found often in S/S season, three piece combinations were the most common, and "H", "I" silhouettes were also popular. Refined black and refreshing orange were used with traditional preppy colors like navy, beige, gray, and white. Contrast color arrangement and neutral, moderate tones were seen repeatedly. Two-thirds of fabrics were pattern-less with clean, bulky, and soft textures. Coordinating accessories like hats, backpacks, books, headsets were used frequently. Among the various preppy fashion types, there were 'traditional preppy' faithful to tradition, 'sophisticated preppy' with refined semi-formal look, 'sportive preppy' with active sports sense, and 'natural preppy' with natural and comfortable senses. In a contemporary preppy look, traditional and practical senses are combined with casual and sportive pieces. This study can provide the data for design planning, interpreting, and applying the fashion themes along with contemporary sensibilities since the preppy look is based on cultural history.

Recently, research and development of the linear compressor are being active. The reason is that the one has not only higher efficiency than reciprocating type, but also lower noise. But because the dicharge valve of linear compressor is operated in high pressure and temperature circumstance, it is important to prevent leakeage. In this paper three other plastic reinforced composite materials were used. Those are TPI, PEEK and PEK which were containing other volume and kind of carbon fibers. First, for assessing mechanical properties, we measured the hardness and the heating property of the trst sepecimen by the microvickers hardness tester and the differential scanning calorimeter respectively. Finally, through FALEX tester, we could know the characteristics of the wear proving the results of before-conducted experiments.

The purpose of the study was to examine how changes of women's sexual identity and gender role were expressed in designs of dance costumes by analyzing costumes used in creative dance works. Related articles, dance magazines, Internet information and dance costumes were used for the analysis of various performance cases to express persona and animus of a woman. The results of the study were as follows: 1. As a woman's role, persona, has recently changed into active propensity, dance directors have come to prefer bold and daring image of female dancer to strongly express animus, the masculine inclination of a woman. 2. Female dancers' costumes were frequently associated with daring body exposure such as body painting on half-naked body, to reflect the above and a number of female dancers dressed daringly in masculine style trom head to toe. Also, pants or hot pants instead of skirt were frequently used as dance costumes to symbolize animus. In addition, colors in dance costumes became vivid and bold in comparison to the simple and soft colors used in the past.

Ag-Cd alloy has been widely used as an electrical contact material, since Ag-Cd alloy has a good wear resistance and stable contact resistance. But nowadays Ag-Cd alloy is not considered as electrical contact material any more due to detrimental effect on environments. Currently, active researches are being performed on ($Ag-SnO_2$ and $Ag-SnO_{2}-In_{2}O_{3}$) as an alternative solution which can fix the remaining environmental problems. However, $In_{2}O_{3}$ is relatively expensive and Ag-Sn alloy has low wear resistance. Our recent research results show that Ag-X%Zn-Y%Sn has similar physical and chemical properties. In the present study, so we tried to change and to optimize the Zn oxide content to over 6 wt% and Sn oxide content with 0.5, 1.0, 1.5 wt%. Results obtained from the experiments on the Ag-X%ZnO-Y%$SnO_2$ are discussed.
