This study was conducted to identify the pain characteristics, family support and physical functioning and to determine predictors of the quality of life in aged women with chronic pain. Method: The questionnaires were collected through direct interview by a trained research assistant from July 2 to August 24, 2001. Subjects were 108 women clients with chronic pain over 65 years of age. Data analyzed frequency, percentage, mean, Pearson's correlation, ANOVA and stepwise multiple regression by SAS. Result: Care providers were mostly spouses and daughters in law. Care providers who took care of elderly for a few hours a day had the highest percentile. Aged women had persistently had chronic pain of moderate intensity and was moderately satisfied with pain management. The mean score of disability due to pain was 3 on a 10 point scale. The mean scores of physical function and quality of life were moderate and there were negative correlations between pain characteristics, physical functioning, and quality of life at the range from r=-.46 to r=-.83. Satisfaction with care, duration of pain, disability due to pain, and physical functioning accounted for 56% of the variance in perceived quality of life for aged women with chronic pain. Disability due to pain was the most predictable variable of quality of life and physical function was the second .Conclusion: The results suggest that care by family, education in pain control, prevention of disability, and maintenance of physical function are important to improve and maintain quality of life in aged women with chronic pain. Therefore, there is a need for program development that enhance family support and nursing intervention that focuses on active pain control.

This study is aimed at standardizing the process of spatial database construction and developing a software tool for process management. Knowhow of five GIS firms and provisions of NGI(National Geography Institute) was analyzed. In this study, the process of spatial database construction was standardized. The system from this study has the capability to manage the process of construction database using GIS and to deal with the metadata of unit map, generated from the process, systematically and continuously. The process was also shown by using either Gantt chart or PERT chart after developing an interface for "MS Project". A software "Visual Basic for Application" was used for this study.

This paper proposes an opportunistic age replacement policy. The system has two types of failures. Type I failures (minor failures) are removed by minimal repairs, whereas type II failures are removed by replacements. Type I and type II failures are age-dependent. A system is replaced at type II failure (catastrophic failure) or at the opportunity after age T, whichever occurs first. The cost of the minimal repair of the system at age z depends on the random part C(z) and the deterministic part c(z). The opportunity arises according to a Poisson process, independent of failures of the component. The expected cost rate is obtained. The optimal $T^{\ast}$ which would minimize the cost rate is discussed. Various special cases are considered. Finally, a numerical example is given.

Sleep disturbances are commonly encountered problems in cancer patients. Sleep has a role in maintenance of immunity, metabolism, and quality of life but little has been known about the prevalence, risk factors, and effects on prognosis of sleep disturbances in patients with cancer. Also little attention has been made on proper assessment and management of sleep disorders in these patients. Recently, there have been some reports that sleep disorders are related with development of many cancers such as breast, colorectal, prostate, and endometrial cancers. An intermittent hypoxia and a disruption of circadian rhythm are considered as one of the possible mechanisms of cancer developments. More aggressive evaluation and meticulous management of sleep disturbances in cancer patients are essential to improve quality of life as well as prognosis.

This paper presents different issues of the real-time compression algorithms without compromising the video quality in the distributed environment. The theme of this research is to manage the critical processing stages (speed, information lost, redundancy, distortion) having better encoded ratio, without the fluctuation of quantization scale by using IP configuration. In this paper, different techniques such as distortion measure with searching method cover the block phenomenon with motion estimation process while passing technique and floating measurement is configured by discrete cosine transform (DCT) to reduce computational complexity which is implemented in this video codec. While delay of bits in encoded buffer side especially in real-time state is being controlled to produce the video with high quality and maintenance a low buffering delay. Our results show the performance accuracy gain with better achievement in all the above processes in an encouraging mode.

Building information modeling refers to combination or set of technologies and organizational solutions that are expected to increase collaboration in the construction industry and to improve the productivity and quality of the design, construction, and maintenance of buildings. For enhanced communication among project participants, various information which BIM model usually includes is provided, furthermore data which contain exchange of unstructured information is needed. If the extension of BIM standard file format for practical use of design Issue information about collaborative design process is fulfilled, the productivity and quality of design will be improved.

In object-oriented software development, reuse has been studied for the enhancement of software quality and software developer's productivity. But improper modeling in design phase and uncontrolled change during maintenance activities have a problem to reuse a class. In this paper we analyze a semantic cohesion of classes using C++ Program dependency graph, and slice a class with cohesion, so that this method supports the re-estimate of class quality and the extensibility of class. Therefore this proposed method in this paper increases the easibility of the restructuring in the reusable systems, when the developer selects a requested component for a object-oriented program development.

Glossing Exposure Concrete is a high quality architectural concrete, i.e., appearance of natural stone and a marbling effect concrete to achieve high quality glassy reflective surface for outer wall of the building. In this study to obtain the conservation and durability of gloss of the "glossing exposure concrete" we developed a from practice and the best mix proportion and derived the optimistic removal time of form to bring out the durable glassy reflective surface and durable concrete. Hereby with the "glossing exposure concrete" obtained, we investigate the accelerate carbonation and accelerate durability test to evaluate the durability factor of this type of concrete.is type of concrete.

In these days, repair materials for leakage cannot help but being taken in temporary way without any noticeable countermeasure. This kind of repair is socially criticized many times that is defective construction even if tills costs a lot. It was not arrange the standard for performance evaluation test method and quality maintenance for materials, even it has been used various injection repairing agent. In conclusion, We suggest that the test method for repair materials for leakage to establish the leakage repairing technology as increase of structure demand, so that the necessity of the establishment of the quality control standard and the performance testing way on the relevant water-proof seal is increasing a lot to regulate the water-proof technology and the leakage repair technology.

Since 1990, urban areas have been expanded rapidly due to the concentration of the population and several development projects including large scale apartment complexes and residential developments. Due to these development projects, the quality and functions of ecosystems have been continuously degraded, regardless of public agencies' efforts introducing development index, guideline, and amendment of law for sustaining the quality of ecosystems. Substantial guideline and content cannot expect the sustainable maintenance of nation's natural resources. Recent improve this situation, ecological planning was introduced, but research data of environments and objective systems were not enough showing the limits. The purposes of this study were to reduce the urban sprawl caused by residential development plans for environment-friendly residential developments, to establish applicable ecological planning, and to suggest the land use plans that reduce adverse effects of developments to nature ecosystem.
