Y. J. KIM, J. G. JI, J. T. KIM, J. H. HONG, J. S. LEE, H. S. LEE, S. B. PARK. A comparison study for mask plantar pressure measures to the difference of shoes in 20 female. Korean Journal of Sport Biomechanics, Vol. 14, No. 3, pp. 83-98, 2004. The purpose of this study was to investigate the test-retest of plantar pressures using the F-Scan system over speeds and plantar regions. 6 healthy female subjects in 20's were recruited for the study. Plantar pressure measurements during locomotor activities can provide information concerning foot function, particularly if the timing and magnitude of the loading profile can be related to the location of specific foot structures such as the metatarsal heads. The Tekscan F-Scan system consists of a flexible, 0.18mm thick sole-shape having 1260 pressure sensors, the sensor insole was trimmed to fit the subjects' right. left shoes - sneakers shoes & dress shoes. It was calibrated by the known weight of the test subject standing on one foot. The Tekscan measurements show the insole pressure distribution as a function of the time. This finding has important implications for the development of plantar pressure test protocols where the function of the forefoot is important. According to the result of analysis it is as follows : 1) Center of force trajectory in women's dress shoes display direct movement, compare with center of force trajectory in Sneaker shoes displays a little bit curved slow pronation movement. Sneaker shoes in forefoot part display very quick supination movement, therefore, this shoes effects negative effectiveness for ankle's stability. Considering center of force trajectory analyzing, the more center of force close straight line, the more movement can be quick movement for locomotion. For foot pressure distribution, center of force trajectory in locomotion is better to curved trajectory with pronation movement. So sneaker shoes style is good shoes considering center of pressure distribution trajectory compare with women's dress shoes. 2) Women's dress shoes increased peak pressure in medial, this is effected by high hill's height. The more increased women's dress shoes's height, the more women's peak pressure will increase, pronation can increase compare with before. Supination movement increase, this focused pressure in lateral, also, supination increased more. If the supination movement increased, foot pressure focused in lateral, therefore, it is appeared force distribution in gait direction. This is bad movement in foot's stability. 3) Women's dress shoes in landing phase displayed a long time, this is when women's dress shoes wear, gait movement is unbalance, so, landing phase displayed a long time. For compensation in gait, swing phase quick movement. 4) Women's dress shoes displayed peak pressure distribution in lateral of rearfoot part, Sneakers shoes displayed peak pressure distribution in medial of forefoot part. Its results has good impact absorption compare with women's dress shoes. In forefoot part, sneakers shoes has good propulsive force compare with women's dress shoes.

Ji, E. S.,Hwang, H.,Park, G. W.,Lee, J. Y.,Lee, H. K.,Choi, N. Y.,Jeong, H. K.,Kim, K. H.,Kim, J. Y.,Lee, S. Springer Science + Business Media 2016 Analytical and Bioanalytical Chemistry Vol.408 No.27

<P>Fucosylation of N-glycoproteins has been implicated in various diseases, such as hepatocellular carcinoma (HCC). However, few studies have performed site-specific analysis of fucosylation in liver-secreted proteins. In this study, we characterized the fucosylation patterns of liver-secreted proteins in HCC plasma using a workflow to identify site-specific N-glycoproteins, where characteristic B- and/or Y-ion series with and without fucose in collision-induced dissociation were used in tandem mass spectrometry. In total, 71 fucosylated N-glycopeptides from 13 major liver-secreted proteins in human plasma were globally identified by LC-MS/MS. Additionally, 37 fucosylated N-glycopeptides were newly identified from nine liver-secreted proteins, including alpha-1-antichymotrypsin, alpha-1-antitrypsin, alpha-2-HS-glycoprotein, ceruloplasmin, alpha-1-acid glycoprotein 1/2, alpha-2-macroglobulin, serotransferrin, and beta-2-glycoprotein 1. Of the fucosylated N-glycopeptides, bi- and tri-antennary glycoforms were the most common ones identified in liver-secreted proteins from HCC plasma. Therefore, we suggest that this analytical method is effective for characterizing fucosylation in liver-secreted proteins.</P>

Purpose: The purpose of this study was to investigate sexual communication among college student couples and to analyze the relationship among sexual communication, sexual attitude, sexual autonomy and sexual satisfaction. Methods: Using a descriptive correlation study design, 281 college student couples were recruited through convenience random sampling from September 18th to October 3rd, 2014. Data were analyzed using average, standard deviation, percentage, t-test, ANOVA, Scheffe test, Duncan’s test and Pearson’s correlation using the SPSS 21.0 program. Results: In both genders, it is identified that high scores for sexual communication is related to sexual openness (male: R= .347, p<0.01 / female: R=.337, p<0.01) higher sexual satisfaction (male: R= .349, p<0.01 / female: R=.336, p<0.01) and sexual autonomy (male: R= .336, p<0.01 / female: R=.364, p<0.01). The same outcome is found when each male and female are grouped as a couple. Among sub-categories of sexual attitude, sexual pleasure was related to sexual communication the most in male (R=.337, p<0.01), female groups (R=.317, p<0.01) and couples (R=.402, p<0.01). Among sub-categories of sexual satisfaction, psychological factor was related to sexual communication the most in the male group (R=.342, p<0.01) and interactive factor was related to sexual communication the most in the female group (R=.317, p<0.01) and couples (R=.402, p<0.01). Conclusion: The significance of this research is that the relations of sexual communication with the other three dependent variables among each gender and couples are shown. In addition, this study suggests the importance of sexual communication between couples which will lead to healthier and better quality of sexual relationships. However, with the lack of sufficient advanced research, there are limitations of analyzing each variables divided by demographic characteristics.

지승한,이능헌,김용혁,김진수,이희규,이덕출 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1

In this paper Dielectric and polarizable properties of 0.9Pb(Mg_(1/3)Nb_(2/3))O_(3)-0.1PbTiO_(3) Ceramics have been investigated as a addition of the amount of La_(2)O_(3)(0≤x≤0.05). The Temperature-dependant electrostictive characteristics of 0.9PMN-0.1PT relaxor ferroelectic system were improved by enhencing the extent of the diffuse phase transition(DPT). This was achieved using PMN-PTceramics by the partial substitution of La at the Pb site. The curie temperature and the maximum dielectic permittivity decreased by substituting La and the electic field-related hysteresis phenomena decreased with increasing La substitution amount.

지원영,이준호 한국고무학회 2002 엘라스토머 및 콤포지트 Vol.37 No.2

고압애자용 실리콘 고무를 제조하기 위해 사용되는 polydimethylsiloxane(PDMS)의 vinyl 기 함량과 실리카의 종류가 전기특성 및 물성에 미치는 영향을 연구하였다. 실리콘 폴리머의 비닐함량이 증가함에 따라 가교밀도와 경도가 높아졌으며 이로 인해 인장강도, 체적저항 및 트래킹 특성이 증가하였다. 건식실리카로 보강된 실리콘 고무가 습식실리카로 보강된 실리콘 고무보다 전기적 특성 및 물성이 우수하였으며 이는 실리카에 존재하는 수분의 함량에 영향을 받는 것을 알 수 있었다. This study was carried out to investigate the influences of the vinyl content of polydimethylsiloxane(PDMS) and type of silica on the electrical and mechanical properties of silicone rubber for high voltage insulation. When the content of vinyl group was increased, cross-linking density and hardness were increased, and tensile strength, volume resistivity and tracking resistance were improved. The mechanical and electrical properties of silicone rubber reinforced with fumed silica were higher than those of silicone rubber reinforced with precipitated silica. It was found that the electrical and mechanical properties of silicone rubber were influenced greatly by the water contents of silica.
