  • Weighting of silk fabrics have long been practiced in silk fabric trading based on the primary consideration of price-weight, and secondary one of quality improvement in handle, luster, and drape properties. Recent trend of practicing weighting of silk fabrics is, however, focused on the improvement of the handle, luster, drape, and other properties. During the finishing processes of synthetic fiber, nylon, comprising amide structure, include the use of tannic acid, especially in the dyeing. A multitude of studies are being implemented in terms of improving fastness to washing, fastness to light of dyed nylon product, or the light fastness of nylon 6 itself. In this study, the effects of various tannic acid treatments on the physical properties related to the handle of nylon 6 and silk fabrics are examined and reviewed. The effects of treatment condition of the tannic acid, e.g., the concentration of the aqueous tannic acid solution, treatment time, and temperature were investigated. As the concentration of the aqueous solution of tannic acid increased, the bending rigidity values of the silk and nylon 6 fabrics increased. The treated fabrics felt stiff to the touch. Within the mild conditions of bending employed in the bending measurement of KES, nylon 6 treated fabric specimen exhibited a trend of improvement of bending resiliency within the range of small bending deformation. The weight of treated fabrics have all increased. The air-permeability values decreased as the treatment concentration increased. However, the decrease tendency of air permeability values may be alleviated by adjusting the fabric count during the tentering or expanding processes, either by tension adjustment or heat treatment. Optimum conditions of the treatment for nylon 6 are 1.25% tannic acid concentration, bath temperature of $85^{\circ}C$, pH 3.1, and those for silk fabric treatment are 1.25% tannic acid concentration, bath temperature of $85^{\circ}C$, pH 3.1. The treatment conditions will lead to the improvement in the properties of fabrics for summer.

  • The purpose of this study was to quantify the biomechanical characteristics of the ground reaction force(GRF) during the Taekwondo's Apkubi, one of the basic movement in Taekwondo and the walking. The GRF profiles under the stance foot of Apkubi movement and walking were directly measured in sample of 20 healthy older persons. In the anterior-posterior and vertical direction, the GRF of the Apkubi movement reached to the peak braking force at 10% of the normalized stance time percent and the peak driving force at 90% of stance time, but that of the walking reached to the peak braking force at 20% of stance time and the peak driving force at 80% of stance time. In vertical force, the GRF of the walking showed two peak values, but that of the Apkubi movement seemed three peak values. Moreover the first peak vertical force was significantly(t=6.085, p<.001) greater in the walking(about 1.8 times of body weight) than the Apkubi(about 1.4 times of body weight). The walking velocity was affected significantly(over p<.05) by the braking impulse, the peak braking force and the first peak vertical force. Futhermore the peak braking force in the Apkubi showed a significant effect on the Apkubi's stride length(p<.01). So, we concluded that the braking force after the right touch down, the stance foot on the ground contributed to move the leg forward.

  • Virtual reality(VR) is known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user's physical presence and environment to allow for user interaction. Virtual realities artificially create sensory experience including sight, touch, hearing, and smell. Owing to the use of a single device in most VR contents, user have difficulty in manipulating user interface and game object. And also immersion of the game goes down because they can't see the mouse and keyboard in virtual space. In this paper, we design and implement the chess game to easily and accurately control user interface to improve the immersion in game.

  • The domestic game market is still on a trend of growth. Particularly, as the demand for mobile games is increased, the mobile version is developed in a growing number of cases even after the launch of the games for PCS. In a bid to search for the effective method of UI design depending on the differences between the platforms, this study analyzed the types of different media in the first place and as the approaches to the UI design based on the affordance concept, implemented on the platform of PCS and implemented on the platform of mobile devices were analyzed as the cases which are the same MMORPG games. Since the differences between the game platforms can cause the variations in the physical size of the screens depending on the environment in which the user interface (UI) is rendered and may often involve the controls implemented by the touch of screens rather than the manipulation based on the keyboard and mouse, they usually give the influences on the direction of UI designs. By analyzing these UI elements based on the affordance concept, it may be possible to find the effective method of UI design in the future.

  • Recently, skin diagnosis has been suggested as a promising tool for discrimination of Sasang Constitution, reported by examining the skin characteristics such as thickness, stiffness, slip, and skin textures like wrinkles and furrows. However, the works had a limitation in that clinical decision on the skin characteristics was made by relying upon oriental medicine doctors' subjective sense of touch. In order to objectify the skin diagnosis and claim its efficacy on the discrimination of the Sasang Constitutions, it is necessary to demonstrate its discrimination capability by providing numerical values in terms of physical quantities obtained from measurements using today's sensors and equipment technologies, which motivated this work as a priliminary step towards objectification of skin diagnosis. The skin characteristics focused in this work is the slip property of the back-hand skin that has been exploited using the dynamic friction measurement system. First, curved geometric effects of the back-hand skin on the measured lateral/vertical force signals were estimated using the artificially designed silicon coated structures, which led to a suggestion on a quality controlled experimental design based upon a empirical analysis model. Second, the experimental design thus suggested has been applied to the measurement of dynamic friction coefficients for two healthy male subjects of Taeumin (TE) and Soyangin (SY), respectively. The result shows that the dynamic friction coefficient is less for the SY subject than for the TE subject around the area of the skin used for diagnosis by the oriental medicine doctor, implying the TE subject's skin is more slippery than the SE subject's that is consistent with the oriental medicine doctor's diagnosis. Hopefully, this work can provide guidelines for obtaining quality data in friction measurement to be collected for discussion on the efficacy of the skin diagnosis and its objectification through statistical analysis.

  • The purpose of this study was to explore nursing needs during labor pain that had been suffered by women who have given birth. It is essential to identify the nursing needs in order to solve nursing problems and to provide better care for the parturients. The sample consisted of 20 women of primiparas and 17 women of multiparas. They underwent normal labor and delivered a healthy baby at term. The data had been collected through the unstructured interviews conducted 1-2 days after delivery in the admission room from March 1998 to March 1999. On average, the interviews lasted for about 30 minutes. Interviews were taken with the consent of the subjects. The data are categorized according to the similarities of their contents. Seventeen subordinate categories and six superordinate categories have been identified. Six superordinate categories are 1) physical nursing needs 2) nursing needs of medical behavior 3) emotional nursing needs 4) informational and teaching nursing needs 5) nursing needs of pain control 6) nursing needs of respect(personality). Seventeen subordinate categories include: comfortable posture, touch, professional knowledge and techniques, duty execution, support, company and talk, stable surroundings, reassurance, information on delivery, explanation of medical behavior, information on surroundings, instruction on the case of pain, arbitrary adjustment, artificial adjustment, respect, interest and reflection of opinions. The result of this research is the same as that of foreign research and the items of the questionnaire in Korea are the same as the foreign one. Despite the same result, however, this dissertation is significant in that the research identifies the parturients nursing needs and classified the data and thus the basis has been formed to develop the tools to assess the nursing needs of the Korean parturients. The findings can be used as the guide for nursing intervention of parturients.
