This study was performed to investigate factors affecting sensitivity and preference for salty tastes of Korean adult females. Sensitivity and preference for salty tastes were determined as detection threshold concentration of NaCl solution and the optimally-preferred NaCl concentration of the bean sprout soup, respectively. A self-administered questionnaire was used to obtain the information regarding general characteristics, self diagnosis of stress, health-related lifestyle practices, dietary habits and food preferences. Dietary intake using 24-hours recall and blood pressure were measured. Salty taste detection thresholds and optimally-preferred NaCl concentrations were 0.0197% and 0.357%, respectively. There was a significant positive correlation between the optimally-preferred salt concentration and age, despite no significant correlation between either sensitivity or preference for salty taste and sodium intake, which was 3,605mg/day. Those who had bread or cereal with milk as breakfast instead of a traditional Korean meal and those who preferred jjigae to soup had significantly higher NaCl preferences for bean sprout soup. Going to bed after midnight and skipping meals (${\geq}3/week$) decreased salty taste sensitivity without reaching statistical significance. Self awareness of one's own health, recent weight changes, family history of hypertension, sleep quality, getting-up time, rate of eating and other food preferences did not affect either perception. Stress level, TV watching, BMI and sodium intake did not have significant correlation to sensitivity or preference. Further research including a large number of well-controlled subjects and more accurate measurement of sodium intake should be directed to find other factors affecting salt preference and sensitivity in order to decrease Na intake and related diseases.

The purpose of this study is a descriptive research study to understand the relationship between sexual attitude, sexual knowledge and gender sensitivity of general college students, and to analyze the effect on gender sensitivity. Participants included 139 general college students. Data collection was conducted through self-reported questionnaires. Data were analyzed using descriptive statistics, t-test, ANOVA and Schffe test for multiple comparisons. The average score of the general college students sexual knowledge was 22.73 out of 38 points, and their sexual attitudes scored 2.92 out of 5points. The average score of gender sensitivity was 2.03 out of 5points. As a result of the study, gender sensitivity was positively correlated with sexual attitude (r=.201, p=.018), and the factors affecting gender sensitivity of general college students were sexual attitude (𝛽=.196, p=.021), and the explanatory power of these factors was 34.0%. Based on the results of this study, it is thought that it is necessary to development of a program that can establish a correct sexual attitude in order to increase the gender sensitivity of general college students.

The purpose of this study is to analyze the relationship between early childhood teachers' play teaching efficacy and play sensitivity and children's play immersion, and to investigate the effect of play teaching efficacy and play sensitivity on children's play immersion. To this end, a survey was conducted targeting 359 early childhood teachers working in kindergartens and daycare centers located in J province. The research tools used in this study were 'Efficacy in Play Teaching' and 'Teacher's Play Sensitivity Scale' targeting teachers and 'Infant Play Immersion Test' targeting infants. As a result of the study, first, the correlation between play teaching efficacy and play sensitivity and young children's play immersion showed that there was a positive correlation between all variables other than the transformation of the sense of time among the teacher's play sensitivity sub-factors and play observation and children's play immersion sub-factors. Second, as a result of examining the effect of teacher's play teaching efficacy and play sensitivity on young children's play immersion, it was found to have a partially statistically significant effect.

Purpose - This study extracts performance-reward factors based on the previous studies related to Herzberg's two-factor theory and performance-reward and proposes a research method to identify how these factors have an influence on task performance directly related to production performance and contextual performance that has an indirect influence. Research Design, Data, and Methodology - This study draws performance-reward factors through Focus Group Interview(FGI), classifies them into economic/uneconomic and direct/indirect factors, draws maintenance/improvement factors and unnecessary ones through IPA, and maximizes the effectiveness of performance-reward factors. Results - It also identifies how performance-reward factors have an influence on internal and external motives based on previous studies, classifies performance-reward factors into task performance and contextual performance and identifies the influence relationship between these, and proposes a research model to identify the roles of equity sensitivity based on equity theory. Conclusion - The findings from this study are expected to lay the groundwork for drawing various methods to reduce the turnover rate of employees and be important resources for reinforcing the competitiveness of businesses by classifying the performance -reward factors that may cause internal and external motives from the small and medium-sized manufacturing perspective and presenting methods to identify if these have an influence on task performance and contextual performance.

A fully coupled thermo-hydro-mechanical model is established to evaluate frost heave behaviour of saturated frost-susceptible soils. The method is based on mass conservation, energy conservation, and force equilibrium equations, which are fully coupled with each other. These equations consider various physical phenomena during one-dimensional soil freezing such as latent heat of phase change, thermal conductivity changes, pore water migration, and the accompanying mechanical deformation. Using the thermo-hydro-mechanical model, a sensitivity analysis study is conducted to examine the effects of the geotechnical parameters and external conditions on the amount of frost heave and frost heaving rate. According to the results of the sensitivity analysis, initial void ratio significantly affects each objective as an individual parameter, whereas soil particle thermal conductivity and temperature gradient affect frost heave behaviour to a greater degree when applied simultaneously. The factors considered in this study are the main factors affecting the frost heaving amount and rate, which may be used to determine the frostbite sensitivity of a new sample.

Internet lowers the search cost to acquire information about products and sellers price information. Because consumers can easily compare prices among different Internet retailers, the price competition among merchants in Internet has been intensified. For online retailers, it is important to differentiate their sites from competitors based upon services rather than prices. This study investigates which factors influence on consumers price sensitivity in Internet book markets and examines whether consumers price sensitivity has any effect on the type of preferred Internet bookstore (hybrid or pure online book stores). Survey is conducted to empirically investigate the relationship among the various consumer attitudes and price sensitivity. The result shows that price search and price importance have effect on the choice of Internet bookstore. Consumers with higher price sensitivity preferred to purchase books from pure Internet bookstores rather than hybrid (click-and-mortar) bookstores. This study provides an exploratory framework that tries to understand consumer behavior about price sensitivity that might provide some marketing implications to lessen the price competition of Internet retailers.

The purpose of this study was to analyze the effect of fiber contents of socks fabric on the subjective sensitivity and emotional sensibility of consumers. We investigated the relationship of subjective sensitivity and sensibility according to fiber contents and color value of socks. We made five plain knit fabrics as specimens, with a combination of chitosan/SUS fiber contents and three value levels of grayish color. The subjects were 15 males and 54 females in the twenties. The data analysis was conducted with Pearson's correlation analysis, ANOVA, Duncan multiple range test, and regression analysis. The major finds were as follows: A factor analysis showed that subjective sensitivity was classified into five factors (bulky, surface-rough, elastic, attention, and variety) and emotional sensibility was into four factors (salience, stability, luxury, and activity). There were significant correlation between the subjective sensitivity and emotional sensibility. The subjective sensitivities of 'surface-rough' and 'elastic' were significantly influenced by fiber contents. The sensibilities of 'salience' and 'luxury' were significantly influenced by fiber contents. Where as the 'salience' and 'roughness' were significant influenced by color value level. According to sex, there were significantly difference in 'bulky', 'elastic' and 'salience'. As a result of the regression analysis, preference, consuming desire and satisfaction appears to be closely related with all subjective sensitivity and sensibility.

Vehicle body frame stiffness affects the dynamic and static characteristics. Vehicle frame structural performance is greatly affected by crossmember and joint design. While the structural characteristics of these joints vary widely, there is no known tool currently in use that quickly predicts joint stiffness early in design cycle. This paper presents the joint design factors affecting on low frequency vibration. The joint factors are joint panel thickness, section property, flange width and weld point space. To study the effect on vehicle low frequency vibration, case studies for these factors are performed. And Sensitivity analysis for section property is performed. The result can present design guide for high-stiffness vehicle.
