  • The life of the transformers is significantly dependent upon the rate of thermal deterioration in the employed insulating materials. Therefore, the study should be based on hot-spot temperature considerations for the life expectancy and possible overload of transformer. We have measured directly temperature of the winding using thermocouples and these test results are compared with those obtained from computer simulation. In this work, our fundamental investigations are well described for the analysis in the thermal distribution of the oil-immersed transformer with the rating of 30kVA.

  • Avascular necrosis of the femoral head is a debilitating disease that leads to destruction of tho hip joint in patients who are in the third, fourth, or fifth decade of life. The total societal cost is so high because these patients are generally young, hold jobs, and have a considerable life expectancy. Therefore, we have to delay or eliminate the need for total hip replacement as possible as we can. The purpose of this review is to provide a current perspective of avascular necrosis of the femoral head.

  • As life expectancy increases, chronic diseases become a problem, and health management in daily life becomes important. With the development of IT convergence technology, personal health records have been collected through various data sources, but they are saved separately by each medical services. Distributed storage of personal health records caused inconvenience about managing the user's health records. In this paper, we designed and implemented an integrated repository and web-based dashboard UI components to solve that inconvenience. The proposed method shows that users can manage their personal health records in the integrated repository effectively and show them through dashboard UI components.

  • The rises of the life index quality together with the medical technology improvement lead to a longer life expectancy. Then a better health care program, especially for elderly, is needed. The common health problems facing those senior citizens are changed from acute diseases to chronic diseases, such as diabetes, hypertension. Then u-Health takes center stage in medical industry. Although u- Health medical device manufacturers have been improving their instruments, these instruments still rely on proprietary technologies without fixed platform. Even if the interface has been provided by the manufacturer, there is no widely-accepted uniform data model to access data of various u-Health devices. IEEE 11073 is a standard attempting to unify the interfaces of all medical devices. In this paper we have proposed a conversion software platform that assures interoperability among medical devices for ubiquitous sensor network. This module uses in order to develop a standard platform of medical system.

  • Great efforts have been made to improve both the quality of life and life expectancy of diabetes by treating problems associated with chronic complications such as neuropathy, retinopathy and nephropathy. In particular, diabetes is an increased risk of developing several types of kidney disease, and the predominant cause of end-stage renal disease in patients with this disorder is diabetic nephropathy. Therefore, prevention of the occurrence and progression of diabetes and its complications has become a very important issue. The scientific observations of an animal model of streptozotocin-induced diabetes, spontaneously occurring diabetes and diabetic nephropathy in this study suggest that one of the Kampo prescriptions, Hachimi-jio-gan comprising eight constituents, is a novel therapeutic agent.

  • With the advantages of power savings, increased life expectancy and fast response time over traditional incandescent bulb, LEDs are increasingly used for many applications including automotive, aviation, display, and special lighting applications. Since the high heat generation of LED chips can reduce service life, degrade luminous efficiency, and cause variation of color temperature, many studies have been carried out on the optimization of LED packaging and heat sinks. In this study, a fin expansion type cooling device using heat pipe, instead of a solid aluminum heat sink, was designed for LED security lightings based on thermal resistance analysis. Numerical analysis and experimental validation were carried out to evaluate its cooling performance.

  • As Korea has just turned into an aging society with the increase of average life expectancy, and the main causes of deaths is cancer and other chronic diseases. And this corresponds to a dramatic increase in medical expenses for the aged. To curve this problem, the hospice care can be an effective alternative, which can provide patients with both quality service and intensive care to help ensure high quality life for the patients. To demonstrate the economical effect of hospice services, a comparative study on the media expenses of geriatric hospitals and general hospitals, which bear similarities in common regarding the characteristics of their patients, is performed. Thus the results of the study can serve as a quantitative indication for the management of hospice services.

  • In order to evaluate the aging of mineral oil immersed distribution transformers, it gathered some insulation oil in over loaded and long time(exceed their service life, 13yrs.) aged transformers in the field, we measured moisture content, acid number, dielectric strength of the oil as defined in KS C 2101 standard. And also, it had been measured dielectric constant, specific resistant, $tan{\delta}$ on aged transformer oil at from $10^{\circ}C$ to $130^{\circ}C$. These results are compared with a new mineral oil. From this study, it can be considered that the analysis of mineral oil may be suitable for evaluation of life expectancy in distribution transformers

  • Abdominal pain associated with chronic pancreatitis is often difficult to control with analgesics and can be severely debilitating with significant impairment of quality of life. In these patients, neurolytic celiac plexus block (NCPB) is an effective treatment option with a low complication rate. However, there is a risk of ejaculatory failure after NCPB, which may be a problem in patients with a long life expectancy. We report a case of ejaculatory failure after unilateral NCPB in a patient with chronic pancreatitis.

  • The increased average life expectancy and an aging society mean a lot of change socially and economically. With the increased population of the new elderly generation, holding a desire to pursue high quality life, plans and marketing strategies towards this group have progressed in the clothing industry. Purchases of clothing will lead the silver clothing industry to a huge consumer market and silver clothing brands are expected to have a lot of potential to grow, especially in department stores in Korea. From now on, there is a need for attacking the market with distinct tactics and characteristics that will satisfy the elderly consumers emotionally. Psychological views towards the elderly generation must be changed and our unique environment state must be considered. With all that, there is also a strong need for researches and development technically and industrially.
