Purpose : The purpose of this study was to find out The effect of Low back pain on the total pattens of Proprioceptive neuromuscular facilitation(PNF). Methods : The subjects of the study were 62 low back pain patients. They were divided into two groups: 31 in the experimental group and 31 in the control group. the experimental group performed modalities and PNF total patterns three times for a week. the control group performed only modalities and ROM exercise three times for a week. Back muscle strength was measured by a back muscle strength measuring machine, the intensity of pain was measured by the Visual Analogue Scale (VAS), and the level of disability was measured by Oswestry low back pain disability index. Study measurements were compared before and after 6 weeks exercise program. The two groups of subjects were assessed by utilizing two different balance measurement: Static standing balance was measured by balance performance monitor (BPM) and Dynamic standing balance was measured by one leg standing(OLS). The scale for static standing balance was measured by using, sway area, sway path, max velocity. Results : The results of this study were as follow: 1) The score on visual analogue scale shows statistically significant increase on PNF group of post test(p<.05). 2) The score on Oswestry low back pain disability index. shows statistically significant decrease on PNF group of post test(p<.05). 3) The change sway area was statistically significant on pre-test and post-test(p<.05). 4) The change sway path was statistically significant on pre-test and post-test(p<.05). 5) The change max velocity was statistically significant on pre-test and post-test(p<.05). 6) The score on one leg standing shows statistically significant increase on PNF group of post test(p<.05). Conclusion : These results of this study indicated that Proprioceptive Neuromuscular Facilitation Total patterns which performed for six weeks had a statistically significant influence on low back pain. If the exercise for muscle strength is performed along with therapeutic stabilizing exercise, a better effect can be expected on low back pain. We hope that this study will provide a basic data for further research with a bigger group and on a long-term effect.

The US railroad network carries 40% of the nation's total freight. Railroad bridges are the most critical part of the network infrastructure and, therefore, must be properly maintained for the operational safety. Railroad managers inspect bridges by measuring displacements under train crossing events to assess their structural condition and prioritize bridge management and safety decisions accordingly. The displacement of a railroad bridge under train crossings is one parameter of interest to railroad bridge owners, as it quantifies a bridge's ability to perform safely and addresses its serviceability. Railroad bridges with poor track conditions will have amplified displacements under heavy loads due to impacts between the wheels and rail joints. Under these circumstances, vehicle-track-bridge interactions could cause excessive bridge displacements, and hence, unsafe train crossings. If displacements during train crossings could be measured objectively, owners could repair or replace less safe bridges first. However, data on bridge displacements is difficult to collect in the field as a fixed point of reference is required for measurement. Accelerations can be used to estimate dynamic displacements, but to date, the pseudo-static displacements cannot be measured using reference-free sensors. This study proposes a method to estimate total transverse displacements of a railroad bridge under live train loads using acceleration and tilt data at the top of the exterior pile bent of a standard timber trestle, where train derailment due to excessive lateral movement is the main concern. Researchers used real bridge transverse displacement data under train traffic from varying bridge serviceability levels. This study explores the design of a new bridge deck-pier experimental model that simulates the vibrations of railroad bridges under traffic using a shake table for the input of train crossing data collected from the field into a laboratory model of a standard timber railroad pile bent. Reference-free sensors measured both the inclination angle and accelerations of the pile cap. Various readings are used to estimate the total displacements of the bridge using data filtering. The estimated displacements are then compared to the true responses of the model measured with displacement sensors. An average peak error of 10% and a root mean square error average of 5% resulted, concluding that this method can cost-effectively measure the total displacement of railroad bridges without a fixed reference.

This study covers the selection of systems measuring the behaviour of the slender structure in the underwater environment and its performance assessment. From a comparison of an instrumentation system that can measure the continuous behaviour along the entire length of the slender structure, the underwater camera system is finally selected as the most appropriate semi-permanent measurement system for Deep-sea Ocean Engineering Basin of KRISO. An experiment on the rigid pipes for a basic performance evaluation of the underwater camera is conducted in this study. The motion of a top excited rigid pipe is measured with the utilization of the underwater camera system. The performance of the underwater camera is evaluated by comparing the movement of a pipe measured by the underwater camera with the measured input signals. Through the top excitation experiment for the slender structure, the real-time three-dimensional measurement of the underwater camera system is qualitatively evaluated in this case. The developed underwater camera system can apply to the system to measure dynamic behaviour of a slender structure and mooring line in Deep Ocean Engineering Basin.

Pharynx is a system transporting foods by peristaltic motion(contraction and expansion movement! into the esophagus and functioning as airway passages. In this study, structural changes of pharyngeal dysfunction are analyzed by biomechanical model using CT and FEM(finite clement method). Loading condition was assumed that equal pressure was loaded sequentially to inside of pharyngeal tissue. In order to analyze the pharyngeal muscular dysfunction by biomechanical model. the pharyngeal dysfunctions was classified into 3 cases. Taking into account the clinical complication by neuromuscular symptoms such as pharyngeal dysfunction after stroke. we assumed that a change of material property is caused by muscular tissue stiffness. A deformation of cross sectional area of the pharynx is analyzed increasing the stiffness $25\%,\;50\%,\;75\%$ in each case on the basis of stress-strain relationship. Based on three-dimensional reconstruction of pharyngeal structure using limited factor - techniques and the optimization procedure by means of inverse dynamic approach. the biomechanical model of the human pharynx is implemented. The results may be used as clinical index illustrating the degree of pharyngeal muscular dysfunction. This study may be used as useful diagnostic model in discovering early deglutitory impediment caused by physiological or pathological pharyngeal dysfunction.

Recently, society's relationship with science is in a critical phase. There was never a time when the issues involving science were more exciting. Many people are deeply uneasy about the safety and ethics of bio-technology. On the other hand, this could be interpreted as a dynamic process in which a new relationship between science and public is reshaping. And in this new relationship citizen participation in science is not a option but a necessity. This article is a case study of 1970's re-combinant DNA debate. Early 1970's bio-technology saw the emergence of an enormously powerful new methodology, recombinant DNA technology. But, at the outset, this technology posed many potential dangers. Concern over possible hazards prompted hot debates and conflict between leading scientists and community, In this process Cambridge Laboratory Experiment Lion Review Board (CERB) is organized by Cambridge City Coun il for assessing the possible risk of recombinant DAN technique. This is one of the first citizen-initiated participation movement in bio-technology. And the debates has come to be a principal focus for many of the most important questions concerning citizen participation in science. This study make a attempt to analyze CERB case. In conclusion, we can confirm the possibility of civil participation in science policy making and decision making from CERB case study. Still, we also realize the limit of CERB case.

The current Korean labour movement is at an impasse that is partly sustained by the idea of "strong" transnational corporations (TNCs) versus "weak" labour, and this perception is based on the "global-local dichotomy," wherein TNCs are depicted as abstract and structured entities operating at the global scale and workers are represented as having a concrete and weak presence within the local sphere. As an alternative perspective to break this "global" capital vs. "local" labour dichotomy, I focus on labour geography, which assumes that labour is not simply a factor of production but a sentient spatial actor that (un-)intentionally produces the landscape of capitalism. Borrowing insights from the multi-scalar perspective, this paper aims to understand the actual methods in which workers utilize spatial strategies through an empirical case study of the Nestlé Korea labour union strike in 2003. Based on this case study, this paper claims that workers are both capable of employing coordinated multi-scalar practices and can be more influential to the economic geographies of TNCs. Additionally, it suggests that workers' scalar practices are actually more complicated and multi-directional as a result of their complex and dynamic interactions with political, economic and cultural forces and actors at diverse geographical scales.

Lewis Carroll's Alice's Adventures in Wonderland expands scope of Children's Literature genre by introducing the discourse of pleasure as opposed to that of didactic discipline. Carroll's narrative is important, not only for children's literature, but also as a forerunner of post/modernism of James Joyce with its language play and linguistic invention. Its treatment of Alice's body change follows the motif of body transformation in myth and literature. Comparing "stasis" of Susan Sontag's character Alice (James) in her play Alice in Bed and "movement" of Carroll's Alice, this study explores the issues of woman's alienation and the dichotomy of mobility/immobility in reality and in their literary representations. Focusing on a female child's double alienation as woman and child, I argue Alice's Adventures in Wonderland is a counter-narrative of alternative bildungsroman. Alice gains her subjectivity through her adventure by power of language and story-telling. Through representation of the dream/adventure of two desiring sisters, Carroll's narrative exhibits subversion of social order and emergence of new order of "chaosmos" out of chaos. As a method of study, this study traces genealogy of "curiosity" in myth and literature as a motivating force that triggers adventure and argues "creative curiosity" is a dynamic energy propelling Alice's adventure.

Today the market of EDMS is esteemed more than 100 billions won. It signifies a comming of age of electronic records. The traditional archival theories which are based on the paper records are confronted with a new challenge. In some leading countries of archival studies reorientation of archives management has been tried by a number of distinguished specialists such as Bearman and Hedstrom since 10 years. As a consequence new paradigm of archival theories has been developed. Also in Korea this new paradigm has been introduced by some expert such as Lee, Sang-Min, Sul, Moon-won, Lee, Seung-Eok. However their arguments are too general to offer a concrete clue for new paradigm. Faced by new age of electronic records, it's important to start a discussion for the reasonable methods of electronic records management at once. The most drastically changed part of record management by the electronic technique is the life-cycle of records. The commonly practiced three-stage life-cycle is to be reduced to the two-stage life-cycle, and the concept of the spatial movement of records is to be changed. It can be also pointed that the public emerges as user from the early creating stage of records beyond time and space. Thus is can be said that the method of the management features dynamic and cohesive. The method of appraisal must be also changed and reproduced, so that it can reflect the various levels considering dynamics of the electronic records. Supposedly it will be a core factor that causes the change of methodology in records management with the change of life-cycle theory. It must be noted that various subjects would be involved in the work of classification and description over time and space and that feedback between them is of important. Description also tends to be made at the crating stage of records and structured dynamically. It results from the change of life-cycle and the introduction of the concept of continuum. Such trend allows us to start discussions on the assumption that description of both creator and archival professionals act together an important role. Of course, it is linked with the methodology in which most descriptions are made automatically at the early drafting stage of the structure. The meat date is formed on the assumption that there should be feedback between areas of automatic description, description of creators and archival professionals. The most important thing in description is to develop a suitable way how it is structured. An alternative must be offered for managing data set. As iweb that is being operated by Myongji university shows, records created in daily business are managed not as electronic records but as date base. This is because they exist outside the repository in the EDMS system. Since data set often has various sources, an alternative for classification needs to be developed. It is now likely that database is filed according to the created year to be transferred automatically to the repository. Over a long-term the total management of database, electronic records and electronic information will be a topic. A right direction of new paradigm will be found for both iweb and E-government, when practice and studies of theories are combined and interacted.

The purpose of this paper is to create an inter-religious dialogue between the Western Christian concept of the spirit and Eastern ch'i philosophy within the category of panentheism. The Hebrew term ruah means 'moving air' and 'wind' which derive from the particular experience of the ancient Hebrew people living in the desert. The Greek pnuema also means 'life' and 'wind' which denote the natural power. Both ruah and pneuma consist of the main idea of the spirit exploring the symbol of relationality of the divine in Western tradition. Eastern ch'i philosophy indicates a vital force for keeping the body and soul alive, which is unconscious and spontaneous. Ch'i as a vital force constitutes cosmogony and cosmology with the constant movement of yin and yang. Yin and Yang as representing earth and heaven are dynamic breaths, blending harmoniously to become all existence. The ethical implication of the inter-religious dialogue between the spirit and ch'i would be the integration and interconnection of heaven, earth, and human beings. The dialogue suggests becoming one body with nature and human community through embodying the non-dualistic spirit of life. The inter-relationality means that since all modalities of existence are made of the cosmic life, human beings are part of the divine cosmic process. This is related to degree of spirituality in the entire chain of being: rocks, trees, animals, humans, and goods represent different levels of spirituality based on the varying composition of the spirit and ch'i. All beings that internally embody with the spirit and ch'i are organically inter-connected, and they are integral part of a continuous process of transformation of life towards holistic liberation of human and nature community.
