The purposes of this study were to assess the effect of therapeutic exercise and to offer an approach to the physical therapy and rehabilitation procedure of the temporomandibular joint (TMJ) following surgery. In this research, 42 patients with TMJ surgery were assigned one of two groups. The experimental group included 21 patients who performed therapeutic exercise, and the control group included 21 patients who did not perform therapeutic exercise. Conservative therapy such as an ice pack, a hot pack, and pulsed ultrasound was applied to both groups. Treatment was applied twice a day during the admission period and, after discharge, everyday for six weeks. Visual analogue scale (VAS), incisal biting force, and joint ROM were measured before surgery and at 30 days after surgery. The results were as follows: VAS (p<0.05), mouth opening (p<0.01), lateral excursion to unaffected side (p<0.05), and protrusion (p<0.05) between experimental group and control group showed statistically significant differences. Incisal biting force and lateral excursion to affected side between experimental group and control group showed no statistically significant difference.

To identify characteristics of elderly inpatients who had long term hospitalization in a general hospital, this study categorized into two groups who were hospitalized for less than 30 days and a group hospitalized for more than 30 days. To compare the groups the independent variables were the sociodemographical characteristics, the medical care utility characteristics, and the disease characteristics and finally analyzed factors affecting the hospitalization period. The data of 18,727 inpatients who were older than 65 years of age by the year 2005 were used and the data were analyzed using SPSS for Windows 12.0. With the results, it is necessary to provide intensive and positive management to elderly inpatients who belong to the more than 30 days group and also necessary to share roles and functions of hospital by medical network with local hospitals and clinics in order to manage long-term elderly inpatients and offer continuous post-management to discharged patients by encouraging them to use a long-term care center or by implementing an early discharge program. This study should provide many studies on how to manage the period of hospitalization efficiently on long-stay elderly inpatients in the future.

This study aimed to investigate leisure activity of the elderly, focused on the elderly education. Two hundred thirty nine elderly persons in the region of Cheongju were selected, and questionnaire was utilized for collecting data. As statistical methods, frequency, %, crosstabs analysis with spsswin was used. Five principle results emerged from this study. First, the elderly education was based on law of welfare of the aged and law of life long education. Second, the elderly education programs consist of four subcategories- intellectual, emotional, social, physical subcategories. Third, many of the elderly participated in physical subcategories. Fourth, the levels of elderly participating in leisure activity was relatively high and differed significantly according to age, time level and cause of participating in leisure activity. Fifth, they were segmented into eight groups by level of education, health and economic status. Among them, the group of positive attitudes and participated on elderly education was more likely to be higher level of education, health and economic status. Based on the results of this study, participating elderly education provides solution of problem and self development for the elderly. In order to prepare Korean society for the aged society, the government need to offer a basis on law and policy for the elderly education, as well as program the elderly education.

The purpose of this study was to investigate consumers' utilization and satisfaction of the current food labeling system, their awareness of the nutrition labeling and its necessity, and their acceptance of the future enforcement of nutrition labeling. Questionnaires were distributed to 500 adult female consumers in Northern area of Kyonggi-do. Out of 402 questionnaires collected 358(89.1%) were analyzed using SAS computer program. The findings of this study were as follow: First, in the aspects of consumers' utilization and satisfaction of the current food labeling system, although they payed much attention to the food labels when they purchased food goods, the degree of their satisfaction in food labels was low. Among items in food labels they payed more attention to the expiration date, the date of production, and the name of manufacturer. However, the current food labeling system does not offer sufficient and reliable informations to consumers. Second, in the awareness of nutrition labeling and its necessity, majority of consumers appeared not to have seen the nutrition labeling in food products either domestic or imported. However, 93% of respondents answered that nutrition labeling is necessary. Third, in terms of the consumers' acceptance of enforcement of nutrition labeling, they were affirmative in bearing the increased costs, and their expectation to the beneficial effects of enforcement of nutrition labeling was stronger than worrying about the disadvantages or side effects of it.

While prior work has noted the importance of knowledge creation in gaining competitive advantages, much less is understood about why firms do not actually use what they create. Building upon institutional approaches to organization studies, we offer a new framework to explain the gap between knowledge creation and utilization. We test our framework in an empirical context of sustainable innovation and environmental technologies where ideas of environmental sustainability have recently gained public popularity and shaped how interested audiences make evaluative assessments of firms. In such a context, firms are apt to perceive the social attention toward sustainability to be a normative pressure, which causes them to create new knowledge and develop technologies consistent with the pressure. Using data from the government-initiated certification system for green technologies, our study finds that firms do not always fully implement new environmental technologies they develop in response to the certification program, the situation we refer to as knowledge decoupling. We also examine a set of conditions under which knowledge decoupling becomes more or less amplified. Taken together, our findings show how a firm's knowledge creation and utilization is shaped by its external institutional environment as well as internal learning processes.

Object recognition is a challenging application for high-performance computing. Currently, the superscalar architecture dominates todays microprocessor marketplace. As more transistors are integrated onto larger die, however, an on-chip multiprocessor is regarded as a promising alternative to the superscalar microprocessor. This paper examines the behavior of the object recognition on the on-chip multiprocessor, which will be employed in general-purpose parallel machines. To obtain the performance characteristics of the microprocessor, a program-driven simulator and its programming environment were developed. The simulation results showed that the on-chip multiprocessor can exploit thread level parallelisms effectively and offer a promising architecture for the object recognition application.

Background: There have been an increasing number of reports about infection-related complications after epidural block, and the analysis of these previous reports may offer valuable information for the prevention and treatment of such complications. Methods: We searched for complications about infection that was related to epidural blockade procedures by using the Medline Search program. We analyzed the types of infection-related complications as well as the potential risk factors, the time course from symptom development to treatment, the causative organisms and the treatment outcomes. Results: Seventeen cases were identified. The types of complications were epidural abscess, subdural abscess, spinal arachnoiditis, bacterial meningitis and aseptic meningitis. Five patients received a single block and twelve patients received a continuous block with catheterization. The most common site of epidural catheterization was the lumbar area and eight patients had indwelling catheters for less than fifteen days. Eight patients had a diabetes mellitus as a risk factor and fourteen patients showed less than seven days from the development of symptoms to treatment. Eleven patients received laminectomy and intravenous antibiotics as a treatment and eight patients had full recovery without neurological deficit. Conclusions: Early diagnosis and treatment is essential for the favorable outcome of infection-related complication after epidural block. In addition, absolute sterile technique should always be performed and patient education concerning these potential complications must be accompanied.

Recently membrane-based gas separation has attracted a great deal of research interests due to the growing demands on greener technologies. Current membrane-based gas separation is dominant by polymer membranes and limited mostly to non-condensable gases even though condensable gases such hydrocarbon isomers are much more attractive. This is primarily due to the limitations of polymer materials. Zeolites and their composites with polymer can offer alternative to current polymeric membranes owing to their superior separation and chemical/thermal properties. This review is intended to provide a brief overview on zeolite and zeolite/polymer composite membranes for gas separation applications.

The clinical clerkship focuses students on developing their ability to perform comprehensive diagnosis and management of patients with common undifferentiated problems by the integration of knowledge and clinical reasoning. Therefore, the clerkship evaluation system should assess their actual problem solving and professional behavior. However, concern remains that clerkship evaluations are imprecise and highly variable. This review is designed to provide faculty members with concepts, options, and a methodology to actively teach and evaluate the clinical clerkship, as well as offer encouragement and inspiration to medical students. We reviewed past and current clinical clerkship evaluations and discuss several tips to improve clinical excellence such as continuity, transparency of the evaluation process, a faculty development program, practical examination of clinical skills, implementation of a checklist for recording exposure and skills, providing prompt and constructive feedback to students, self-evaluation of professional performance, varying multi-faceted assessment combinations, being outpatient clinic-centered, and having dedicated faculty members who give students one-on-one contact with a preceptor.
