The pain is common among individuals with physical disabilities. It can interfere with therapy since patients with pain can become uncooperative and reluctant to move. This paper reviews the natural physiological mechanisms that can reduce pain perception, and considers physiological mechanisms which contribute to clinical pain by describing how the pain system changes its sensitivity depending upon the body's needs. The peripheral and central mechanisms contributing to sensitised nociceptive system are described with reference to the symptoms of clinical pain such as hyperalgesia, allodynia sopntaneous 'on-going'-projected and referred pain. It is suggested that in some chronic pain the nociceptive system maintains a state of sensitivity despite the absence of on-going tissue damage and under such circumstances the nociceptive system itself may have become dysfunctional. Such situations are often initiated by damage to nervous tissue which results in changes in the activity and organization of neuronal circuits within the central nervous system. The ability of the nociceptive system to operate in a suppressed state is also discussed with reference to pain modulation. The physical therapist can help facilitate the activation of these mechanisms through a combination of noninvasive modalities, functional activities, and the therapeutic use of self.

Purpose: To investigate the abilities to act and fear of falling in home-dwelling elderly. Methods: This study interviewed 351 home-dwelling elders residing in Seoul and Gyonggi-do using a Survey of Activities and Fear of Falling in the Elderly. Results: Of the 351 subjects, 203(57.8%) had activity restrictions. The main three activities that the subjects could not perform were going out when it is slippy, reaching something overhead and walking crowded places outside. According to general characteristics, performable activities were significantly fewer in subjects perceiving that their health status was low that those perceiving that their health status was high. On a scale of 3 points for fear of falling, the average score of the subjects was 1.46. The highest score of fear of falling was 2.62 for the activity of going out when it is slippery, next 1.87 for the activity of reaching something overhead. There was a significant inverse relationship between subjects' abilities to act and fear of falling. Conclusions: The significant variables associated with fear of falling were gender(female), educational background, economic status (low-income), and experience of falls during the last one year. Thus further study is necessary, focused on the vulnerable population in order to prevent falls and to reduce fear of falling.

Prosodic features of speech are known to play an important role in the transmission of linguistic information in human conversation. Their roles in the transmission of para- and non- linguistic information are even much more. In spite of their importance in human conversation, from engineering viewpoint, research focuses are mainly placed on segmental features, and not so much on prosodic features. With the aim of promoting research works on prosody, a research project 'Prosody and Speech Processing' is now going on. A rough sketch of the project is first given in the paper. Then, the paper introduces several prosody-related research works, which are going on in our laboratory. They include, corpus-based fundamental frequency contour generation, speech rate control for dialogue-like speech synthesis, analysis of prosodic features of emotional speech, reply speech generation in spoken dialogue systems, and language modeling with prosodic boundaries.

The purpose of this paper is to investigate how the young fashion which maintains a large share of fashion market emerged in the 1960s, its characteristics and what its influences on the contemporary fashion industry are. In particular, I am going to consider the significance of the young fashion by looking at the formation of niche market, the emergence of mass market for fashion, the expansion of aesthetic categories. we will be able to see the 60s young fashion of the young generation who emerged as new consumers in mass consumer culture exerted important influences on the contemporary fashion industry. First, the counterculture of young generation who rebeled against the uniformity of mass production helped the formation of new niche market. Second, the young fashion which pursued the lower prices for fashion made a big contribution to the popularization of fashion. The young generations tendency to demand new things and rapid change coincided with that of inexpensive popular fashion people can buy and change more easily than expensive high fashion. Lastly, the playful tendency of the young fashion expanded the aesthetic boundaries of the clothing, going beyond the uniformity of modernism with the emergency of diverse fashion materials - fabric and textiles - enable by technological development and the miniaturization of forms as revealed in mini skirt.

This paper reorganized five service qualities dimensions of ski-resorts, then derived the improvement priority order of the service quality through a satisfaction measure considering the importance. There're more competitive situations to guarantee customers using the skies and snowboards is a major sports in winter season. In these competitive environments, this paper's going to propose a predominant-competitive strategies for improving the service quality of ski-resorts. This study measured the satisfaction considering the importance of service quality target on customers has an experience ski resort service quality to improve ski resort service quality. This study using Performance Model decide a priority order about a particular item improvement, then is going to present a guideline that can improve the service quality more exactly. As a result of the study the factors that is important to the customer were prime physical factor, access, assistance physical factor, staff service and assistant service, an improvement priority order were accommodation and eating-drinking facilities, waiting time of a slope and lift/gondola, entertainment/shopping facilities in the resorts, equipment rental and lift fare.

Since 2002, the market opening of architecture design, reformation efforts and corresponding studies on architectural education system in Korea have been made to meet the standards of international recognition and accreditation. As a result, the importance of design in architecture program has been recognised and reflected on the reformations on the curriculum by increasing hours in design courses, for instance. At the same time, much need is demanded on the qualitative improvement on architectural design education, both on its contents and structure. In addition, the current reformational changes on architectural education in Korea have their bases on the performance evaluation criteria of National Architectural Accrediting Board of America. To improve the quality of architectural program accounting the unique cultural and social requirements of Korea, various perspectives from other countries, besides American system, are needed to be considered and studied for the on-going reformations in architectural education. The purpose of this study is to contribute to the current on-going reformation efforts on the improvement of architectural design education. The study will closely examine the current architectural curriculum in German university and provide a systematic program for introductory architectural design curriculum.

Ocean-bottom seismic survey is a seismic acquisition technique which measures data by installing 4-component receiver on the sea floor. It can produce more improved data in quality than any other acquisition techniques. In the ocean-bottom seismic survey, however, the number of receivers is limited due to high cost. Since only a small number of receivers are used for acquisition, ocean-bottom seismic data may suffer from discontinuities of events over traces, which can result in spatial aliasing. In this paper, we implemented Kirchhoff migration using mirror-imaging algorithm to improve the quality of ocean-bottom seismic image. In order to implement the mirror imaging algorithm, the seismograms should be separated into up-going and down-going wavefields and the down-going wavefield should be used for migration. In this paper, we use the P-Z summation method to separate the wavefield. Numerical examples show that the migration results using mirror imaging algorithm have wider illumination than the conventional migration, especially in the shallow layers.

Ice-going ships such as icebreakers, icebreaking tankers, and icebreaking LNG carriers are subjected to wave loads in open water and ice loads in ice-covered water. In terms of the ship's structural design, the local ice load is important. The fatigue failure due to repeated ice loads is also important. ISO 19906 specifies the assessment of the fatigue limit for a polar offshore structures. In addition, Lloyd's Register refers to fatigue damage based on ShipRight FDA ICE. In ShipRight FDA ICE, the fatigue damage indices due to wave and ice loads are simply presented as 0.5 for each load. It also states that the sum of the two fatigue damage indices should not exceed one. This study calculated and analyzed the fatigue damage index and fatigue life considering ARAON's voyage schedules and the assumed Antarctic voyage based on data measured during the Arctic voyage of ARAON in 2010.

This paper represents a basic statistical examination on the navigability of ocean-going ship from the point of estimating the time lasting period when propeller racing occurred by using the basic probability theory and the statistics. The propeller racing is one of the most important seakeeping qualities in relation to the safety of the main engine and shafting system. The trend of the racing has been mainly investigated in order to estimate allowable maximum propeller diameter, operation of ocean-going ships, etc.. In those studies, the propeller racing generally and mainly means the situation (propeller exposed) in which the relative motion amplitude between ship hull and wave surface would exceed a depth of point in rotary disk propeller. Therefore, it seems that the magnitude of the amplitude and its exceeding frequency of propeller racing have been examined as a principal subject of study as usual. However, the time during which the amplitude exceeds the depth of point, that is, the propeller exposes in the air, must be also one of most important factor affecting the trend of propeller racing. Then, this paper proposes a new practical method for estimating the time lasting of exposed propeller related to propeller racing in rough-confused seas on the basis of the linear strip theory and the statistics. And, numerical examples of estimating the propeller racing probability are given for four wide ship forms. Finally the usefulness of the proposed method for predicting propeller racing based on the time lasting period is discussed.
