  • The purpose of this study was to investigate the crease recovery and the elastic recovery as a function of the direction of plain woven fabrics. The crease recovery was measured by Mosanto's Method and the elastic recovery was investigated by Autograph for ten kinds of plain woven fabric samples. The results were as follows; 1. Values of crease recovery were in the order of bias>weft>warp. 2. The lengthening of recovery time had a little effect on crease recovery. 3. The directions of crease recovery were affected by that of thread twist. 4. The linearity was shown between total crease recovery and warp-weft crease recovery. 5. The linearity was found between crease recovery and elastic recovery in the fabrics.

  • In this study, inelastic displacement ratios and ductility demands are investigated for SDOF systems with period range of 0.1-3.0 s. with elastoplastic behavior considering soil structure interaction. Earthquake motions recorded on different site conditions such as rock, stiff soil, soft soil and very soft soil are used in analyses. Soil structure interacting systems are modeled with effective period, effective damping and effective ductility values differing from fixed-base case. For inelastic time history analyses, Newmark method for step by step time integration was adapted in an in-house computer program. Results are compared with those calculated for fixed-base case. A new equation is proposed for inelastic displacement ratio of interacting system ($\tilde{C}_R$) as a function of structural period of interacting system ($\tilde{T}$), strength reduction factor (R) and period lengthening ratio ($\tilde{T}/T$). The proposed equation for $\tilde{C}_R$ which takes the soil-structure interaction into account should be useful in estimating the inelastic deformation of existing structures with known lateral strength.

  • This paper presents durational characteristics of Korean distant-talking speech using speech data, which consist of 500 distant-talking utterances and 500 normal utterances of 10 speakers (5 males and 5 females). Each file was segmented and labeled manually and the duration of each segment and each word was extracted. Using a statistical method, the durational change of distant-talking speech in comparison with normal speech was analyzed. The results show that the duration of words with distant-talking speech is increased in comparison with normal style, and that the average unvoiced consonantal duration is reduced while the average vocalic duration is increased. Female speakers show a stronger tendency towards lengthening the duration in distant-talking speech. Finally, this study also shows that the speakers of distant-talking speech could be classified according to their different duration rate.

  • In this study, strength reduction factors are investigated for SDOF systems with period range of 0.1-3.0 s with elastoplastic behavior considering soil structure interaction for 64 different earthquake motions recorded on different site conditions such as rock, stiff soil, soft soil and very soft soil. Soil structure interacting systems are modeled and analyzed with effective period, effective damping and effective ductility values differing from fixed-base case. For inelastic time history analyses, Newmark method for step by step time integration was adapted in an in-house computer program. Results are compared with those calculated for fixed-base case. A new equation is proposed for strength reduction factor of interacting system as a function of structural period of system (T), ductility ratio (${\mu}$) and period lengthening ratio (T/T). It is concluded that soil structure interaction reduces the strength reduction factors for soft soils, therefore, using the fixed-base strength reduction factors for interacting systems lead to non-conservative design forces.

  • Purpose: The purpose of this study was to explore the concept of deconditioning within the field of nursing allied health sciences. Method: The concept analysis method described by Walker and Avant(1995) was used. Critical attributes, antecedents, consequences, and empirical referents were identified. Also model, borderline, contrary and related cases were proposed. Results: The definition of concept 'deconditioning' was a decrease in the function of general system that occured after long periods of immobility and might be marked by frail upon return to normal conditions. The attributes of deconditioning were as follows; 1) the deconditioning was caused by lengthening of physical inactivity; 2) the deconditioning state was resulted by respiratory system, cardiovascular system, musculoskeletal system, hematologic system and generalized manifestation; 3) the deconditioning state could be reconditioned. 4) The reinforced functions by exercise could be compromised by physical inactivity. Conclusion: Deconditioning is important concept in nursing practice since it occurs commonly in any patients who lack physical activity for long time and affects many aspects of clinical outcomes, but it could be reversible by nurses' efforts.

  • Resistive therapeutic exercise prescription goal is to improve functional performance and capabilities through the development of increased muscular strengh endurance or power. Resistance can be applied to either dynamic or static muscle contractions. Resistive therapeutic exorcise can be carried nut concentrically, eccentrically, isometrically, isokinetically. Neurodevelopmental treatment has not resistive therapeutic exercise concept. But proprioceptive neuromuscular facilitate techniques have resistive therapeutic exercise concept with pattens and techniques. It is aid muscle contraction, motor control and increase strength. Manual muscle testing will help the therapist establish a qualitative and quantitative baseline level of strength. Manual resistance maybe applied a against controlled lengthening contraction re static contraction of a muscle. A repetition maximum is not easy to calculate and is not the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Oddvar Holten Diagram is essy to calculate and is the most accurate method available today to measure strength before of after a resistive therapeutic exercise program. Plyometric training emphasize the development of muscular power and coordination. Quick bursts of force in functional movement patterns are often necessary of a patient is to return to high-demand occupational, recreational or sports related activities.

  • The main purpose of retaining wall methods for deep excavation is to keep the construction site safe from the earth pressure acting on the backfill during the construction period. Currently used retaining wall methods include the common strut method, anchor method, slurry wall method, and raker method. However, these methods have drawbacks such as reduced workspace and intrusion into private property, and thus, efforts are being made to improve them. The most advanced retaining wall method is the prestressed wale system, so far, in which a load corresponding to the earth pressure is applied to the wale by using the tension of a prestressed (PS) strand wire. This system affords advantages such as providing sufficient workspace by lengthening the strut interval and minimizing intrusion into private properties adjacent to the site. However, this system cannot control the tension of the PS strand wire, and thus, it cannot actively cope with changes in the earth pressure due to excavation. This study conducts a preliminary numerical analysis of the field applicability of the controllable prestressed wale system (CPWS) which can adjust the tension of the PS strand wire. For the analysis, back analysis was conducted through two-dimensional (2D) and three-dimensional (3D) numerical analyses based on the field measurement data of the typical strut method, and then, the field applicability of CPWS was examined by comparing the lateral deflection of the wall and adjacent ground surface settlements under the same conditions. In addition, the displacement and settlement of the wall were predicted through numerical analysis while the prestress force of CPWS was varied, and the structural stability was analysed through load tests on model specimens.

  • Purpose: The presence of epicanthal fold and the absence of supratarsal fold are characteristics of Korean eyelids. There has been many surgical procedures to eliminate medial epicanthal fold but those procedures focus on the lengthening of horizontal palpebral fissure and the shortening of intercanthal distance so that the shape of eye had tendency to be sharp. The authors suggest that the supermedial shifting of epicanthal fold enhance the aesthetic result. Methods: From Sep 2006 to May 2007, total 17 women(mean age 22) with Type III epicanthal fold underwent epicanthoplasty using author's modified Uchida method. The design for epicanthoplasty was drawn superolaterally along epicanthal fold and split V-W plasty was done to shift the epicanthal fold superomedially. Also non-incisional double-eyelid operation was underwent. Results: The epicanthal fold was shifted in superomedially, intercanthal distance was shortened and double-eyelid was achieved. The patients were satisfied with the result and no major complication was noted. Conclusion: This method can be effective in correcting the epicanthal fold of Korean eyelid by shifting the epicanthal fold superomedially to make the shape of eye aesthetically without noticeable scar.
