  • The purpose of this study is to examine the effects of human touch on turnover intention of ground handling employees at airport. Additionally, this study examines a comprehensive mediating effect of the work schedule and workload between human touch and turnover intention. To examine them, over 700 ground handling employees from six international airports of South Korea were surveyed using the simple random sampling method. The instrument for data collection was a questionnaire, and it was developed based on previous research results. The methodology adopted in this study is the structural equation modeling (SEM). According to SEM analysis, it was proven that both psychological and physical human touch have a significant effect on turnover intention of the employees. Work schedule played a mediating role among all three factors of human touch and turnover intention. However, workload has a mediating effect only between communication human touch and turnover intention. Based on the above findings, theoretical and practical implications are also discussed.

  • Recently, the researches based on vision about user attention and action awareness are being pushed actively for human computer interaction. Among them, various applications of tabletop display system are developed more in accordance with touch sensing technique, co-located and collaborative work. Formerly, although supported only one user, support multi-user at present. Therefore, collaborative work and interaction of four elements (human, computer, displayed objects, physical objects) that is ultimate goal of tabletop display are realizable. Generally, tabletop display system designs according to four key aspects. 1)multi-touch interaction using bare hands. 2)implementation of collaborative work, simultaneous user interaction. 3)direct touch interaction. 4)use of physical objects as an interaction tool. In this paper, we describe a critical analysis of the state-of-the-art in advanced multi-touch sensing techniques for tabletop display system according to the four methods: vision based method, non-vision based method, top-down projection system and rear projection system. And we also discuss some problems and practical applications in the research field.

  • The purpose of this study was to investigate the effects of heat transfer characteristics of fibers on the Qmax of insulating nonwovens. The effects of fiber type, moisture content, washing cycles on the Qmax were observed. The correlations between Qmax measured by KES-F7 system and subjective warm/cool touch perception test was analyzed. The results obtained were as followed: 1. Heat transfer characteristics of fibers effected on the Qmax of insulating nonwovens. 2. Moisture transport properties of fibers effected considerably on the Qmax of nonwovens and the increasing rate of Qmax by increasing moisture content was much higher at wool than polyester. 3. As a result of subjective perception test, subjective warm/cool touch and wettness of wool nonwoven was increased obviously by increasing moisture content. 4. At the same moisture content, wool nonwoven showed higher subjective cool touch and wetness than polyester. 5. In the physical properties of nonwovens, thickness was the most effective factor on the Qmax of insulating nonwovens.

  • Reverse engineering is reproducing products by directly extracting geometric information from physical objects such as clay model wooden mock-up etc. The fundamental work in the reverse engineering is to acquire the geometric data for modeling the objects. This research proposes a novel method for data acquisition aiming at unmanned fast and precise measurement. This is come true by the sensor fusion with CCD camera using structured light beam and touch trigger sensor. The vision system provides global information of the objects data. In this case the number of data and position allocation for touch sensor is critical in terms of the productivity since the number of vision data is very huge. So we applied wavelet transform to reduce the number of data and to allocate the position of the touch probe. The simulated and experimental results show this method is good enough for data reduction.

  • In this paper, we use VR technologies including touch processing technologies and haptic devices to offer touch of fish objects to users. The Omni, a kind of haptic device and made by Sensable Inc., is used to implement multi touch model in VR space. In addition, Matlab/Simulink and proSENSE Virtual Touch Toolbox of Handshake Inc., are used as programing tools. Functions needed to describe the movement of x, y, and z axis respectively are applied to delineate the natural movement of fish objects modeled with 3D. Such movements offer realistic physical interactions to two users controlling multi point respectively. In experiment, to perceive the appearance of 3D object by touch and to feel the respiration by touch are well conducted. We also verify that it is possible to develop games or contents through multi participation in VR Space by using multi point.

  • Each cotton fiber is a unicellular hair collected from the seed of cotton plant. The fiber contains many convolutions along its length. Mercer was the first to suggest caustic soda treatment of cotton in commercial application. Mercerization has been commercially used since Lowe's suggestion to endow cotton with increased strength and affinity for dyes with additional properties such as fabric touch or luster. In this study, cotton fabric specimens were mercerized to investigate the changes in physical and mechanical properties pertaining to the hand or touch of fabrics. Physical properties were measured using the KES(Kawabata Evaluation System).

  • Various high-touch textile products have been developed recently including ultra-fine denier filament yarn fabrics. The touch or hand of high value-added products is of prime importance. Physical and mechanical properties of fabric specimens, ultra-fine denier filament yarn fabric specimen, 100% wool fabric and wool/polyester 50:50 fabric,were measured using the KES. Compressibility of the ultra-fine denier fabric is recommendable, possibly due to the good bulk property of the specimen. Overall, the THV of the ultra-fine denier fabric is positioned between those of the 100% wool fabric and wool/polyester 50:50 fabric. Observed differences in the physical and mechanical properties explain the fabric specimen characteristics reasonably.

  • Purpose: This study aims to explore the relationship between exclusion experiences and tactile sensations in online contexts, moving beyond existing frameworks of social exclusion research. Social exclusion induces psychological and physiological pain similar to physical pain, which can lead to various behavioral responses aimed at overcoming these distressing experiences. This study focuses on the potential of touch to mitigate psychological and physiological pain. Individuals who experience social exclusion feel emotional distress, leading to an increased desire for physical contact, which is expected to influence their responses to positive tactile products. Data and methodology: To validate this, the study examines how individuals who have experienced social exclusion respond to tactile products, such as sweaters, in online environments. Results: The results indicate that participants in the exclusion condition had a higher purchase intention for tactile products compared to those in the control condition, confirming the psychological mechanism of the desire to touch these products. Conclusions: This research is the first to analyze the relationship between social exclusion and tactile products, contributing to the expansion of the field of social exclusion studies. Additionally, it provides practical implications for marketers regarding the exposure of products targeting individuals experiencing social isolation and emotional loneliness.

  • Purpose: This study is aimed to confirm the effects of Yakson therapy on the growth and physical response of preform infants, and maternal attachment to them compared with GHT therapy. Method: The design of this study is nonequivalent control group with repeated measuring by quasi experimental study. The subjects are preterm infants in 26 - 34 gestational age hospitalized in the NICU of 4 university hospitals with an experimental group of 15 and a control group of 14. Yakson therapy consists of three phases: laying a hand, caressing by hand, and laying a hand again taking 5 minutes for each phase. Result: As a result of administering Yakson therapy to preform infants; the average weight gain of the Yakson group was higher than that of the GHT group, but there is no significant difference between groups. The oxygen saturation and maternal attachment difference between the Yakson and the GHT group were not significant. Significant differences in the average daily increase of oral intake and apical pulse rate were observed between the Yakson group and GHT group. Conclusion: These data suggested that Yakson therapy may be an effective nursing intervention which can facilitate growth and physical response of preform infants.
