Compared to the present clinical field strengths, MR at 47 and above promises to improve anatomic imaging quality by factors, and to bring metabolic and functional imaging to the forefront of research and diagnostic modalities. While human bore sized magnets as high as 9.4T are now installed, realization of the potential benefit of these magnets will require more of the MR system than a simple field, frequency or power scaling from technologies used at lower fields. New constraints on the high field MR studies, both physical and physiological, will require new technical developments to be considered for the highest field systems.

This paper discusses the social changes in the late 19th century that provided a historical background in the appearance of the ready-to-wear clothing in the West. It examines the social meanings of the appearance of the ready-to-wear clothing at the time and traces the origins of these social characteristics to the book published in the $16^{th}$ century by Thomas More, Utopia. The results of this study can be summarized as the following. First, the appearance and expansion of the ready-to-wear clothing coincided with the social transition from a class-based society to a democratic society in the west in the $19^{th}$ century. Second, uniforms were produced in the $18^{th}$ century Europe in order to distinguish different classes and ethnic groups, with the military uniforms being the most visible example. Frequent military campaigns in Europe resulted in the increasing demand and expansion of military uniforms, which later became the basis of the standardization of the men's clothing with uniforms. Third, the women's ready-to-wear clothing appeared later than their male counterpart and was made possible by the simplification of design, an important characteristic of women's wear in the later period. Fourth, the social characteristics of the ready-to-wear clothing can be traced to a democratic and egalitarian society without personal properties that was depicted in the book of Utopia by Thomas More. Fifth, one of the characteristics of the ready-to-wear clothing can be found in the description of Utopia, in which everyone in Utopia wears a clothing of the same form for life.

PURPOSE: This study examined the relationship between lumbar instability and shortening of the iliopsoas muscles in patients with chronic low back pain. METHODS: Forty-nine patients with chronic low back pain participated in this study. The modified Thomas test was used to examine the shortening state of the iliopsoas muscle. The length of the iliopsoas muscle was measured using the hip flexion angle, and those with a flexion angle of 10° or more were classified as positive. Five subtests were used for the lumbar instability test: testing for prone lumbar instability, passive lumbar extension, anterior-posterior mobility, passive straight leg raise, and age. Those who tested positive for at least three of these tests were classified as positive for the lumbar segment instability test. RESULTS: There was a significant association between the results of the lumbar instability test and the shortening of the iliopsoas test (p < .05). After analyzing the association between the iliopsoas length test and the five lumbar instability subtests, the results of the prone lumbar instability test (p < .001) and the anterior-posterior mobility test (p < .05) showed a significant association with the iliopsoas length test. CONCLUSION: The association between lumbar instability and shortening of the iliopsoas muscles was examined in 49 patients with chronic low back pain. Patients with shortened iliopsoas muscles tested positive in the lumbar instability tests more often. Hence, the length test of the iliopsoas muscle can be used to determine lumbar instability in patients with chronic low back pain.

The current study aims to 1) investigate how fashion is perceived in societies that utopian novels were born and 2) what fashion means in utopian worlds by content analyzing two utopian novels, Thomas More�s Utopia and William Morris�N ews from Nowhere. The analyses of More�s Utopia and Morris�s News from Nowhere revealed that both utopian societies made corrections from our (imperfect) societies to increase happiness of people. Dresses of those two utopian societies were described as comfortable, pleasant, and attractive. There was a difference in design in that More considered simple and natural designs as the best whereas Morris considered human processed, labor intensive designs as the most attractive. However, fashion did not exist in either utopian world. It is reasonable to say that utopian societies were anti fashion in general due to the conflicting natures of fashion and utopia.

The cracking problem in concrete is widespread and complex. This paper reviews the problem and focuses on those parts of the problem that are more readily solved. Polymer fibers are shown to have promise in several important areas of the cracking problem. To investigate one of these areas of the cracking problem more completely, an experimental research program focusing on the early-age properties of fibers was carried out. This study researched the properties of four polymer fibers; two of the fibers were macrofibers, and two were microfibers. Each fiber was tested at several dosage rates to identify optimum dosage levels. Early-age shrinkage, long-term shrinkage, compressive strength, and tensile strength were investigated. Long-term shrinkage and strength impacts from the polymer fibers were minimal; however, the polymer fibers were shown to have a great impact on early-age shrinkage and a moderate impact on early-age strength.

Using the case of the Ghent University and its Technology Park, we will illustrate how changing policies and practices at the level of the university concerning research valorization have an impact on our science park. We will also demonstrate how the evolving nature of our science park has a clear impact on the university, as the science park becomes more and more an integral part of the university knowledge eco-system. We will also highlight the involvement of Ghent University in the Korea Songdo Global University Campus Project.

The purpose of this article is to continue the study of q, 𝜔-special functions in the spirit of Wolfgang Hahn from the previous papers by Annaby et al. and Varma et al., with emphasis on q, 𝜔-Apostol Bernoulli and Euler polynomials, Ward-𝜔 numbers and multiple q, 𝜔power sums. Like before, the q, 𝜔-module for the alphabet of q, 𝜔-real numbers plays a crucial role, as well as the q, 𝜔-rational numbers and the Ward-𝜔 numbers. There are many more formulas of this type, and the deep symmetric structure of these formulas is described in detail.

Germany as a densely populated and heavily industrialised country has a long and broad experience in handling contaminated sites. With this presentation we want to describe some main aspects of the soil protection policies and the remediation of contaminated sites in Germany. Due to the history of working on contaminated sites in Germany the Federal Soil Protection Act came into force in 1998. A lot of programmes and network in Germany and in Europe, funded by the State or the European Union, helped developing new measures and techniques for remediation and also for implementing regulations for the involved authorities. Questions like 'who is responsible？' and 'who has to pay for measurements and the remediation？' became more and more important. In the near future there will be an official European Soil Protection Policy (is expected in June 2004). Besides the contaminated sites also other soil protection policies as 'Reducing the land consumption' are pursued and an indicator is developed.and an indicator is developed.

Managing quality is nothing new, but it increasingly become more challenging. Demands form customers, flatter organizations, measuring and assessing outcomes, stiffer competition for resources, technology, environmental concerns and others, all have created changes in the workplace for which enhanced leadership is needed. TQM, CQI, TQL, (managing quality), other acronyms can be summarized as a means of moving an organization into the new millennium with a keen focus on people, service, efficiencies, effectiveness and excellence. It is not an accident. It is the result of a clear, well-directed strategically focused thinking. Attention to quality encourages individuals and teams throughout organizations to continually learn, think and contribute ideas on how to explore processes that affect them. The organization must change into a learning organization that seeks to continually improve its processes and services. This learning attitude requires a cultural shift from autocratic to more participatory leadership. This presentation will examine the principles and lessons learned form implementation of quality initiatives from different organizations. Many of the themes shared are independent of the source and, as such, may be helpful in validating what you are doing or give you ideas on leading and implementing change within your organizations.

The modern era of water quality modeling in the United States began in the 1960s. Pushed by advances in computer technology as well as environmental sciences, water quality modeling evolved through five broad periods: (1) initial model development with mainframe computers (1960s - mid 1970s), (2) model refinement and generalization with minicomputers (mid 1970s - mid 1980s), (3) model standardization and support with microcomputers (mid 1980s - mid 1990s), (4) better model access and performance with faster desktop computers running Windows and local area networks linked to the Internet (mid 1990s - early 2000s), and (5) model integration and widespread use of the Internet (early 2000s - present). Improved computer technology continues to drive improvements in water quality models, including more detailed environmental analysis (spatially and temporally), better user interfaces and GIS software, more accessibility to environmental data from on-line repositories, and more robust modeling frameworks linking hydrodynamics, water quality, watershed and atmospheric models. Driven by regulatory needs and advancing technology, water quality modeling will continue to improve to better address more complicated water bodies and pollutant types, and more complicated management questions. This manuscript describes historical trends in water quality model development in the United States, reviews current efforts, and projects promising future directions.
