  • This paper is concerned with figuring out a scheme to facilitate UML utilization through examining the factors which affect the intention to use UML. For this, we conducted a survey of those factors among software engineers in IT service companies. In order to examine the factors affecting the intention to use UML, we developed a model by combining the Technology Acceptance Model and the Innovation Attributes Theory, which have been proved to explain well about the acceptance of new technologies and services. Statistical analysis shows that the subjective norm which is one of social factors has significant influence on the career consequences, and also on the compatibility when the result of UML utilization is demonstrable. The career consequences, the compatibility and the ease of use are found to have significant influence on the usefulness perception of UML utilization, implying that the recognition that one's future career can be affected in the long term by UML utilization is important in shaping how one perceives the usefulness along with the compatibility with one's current task type and the ease of use. The usefulness and the compatibility are evaluated to be the factors that have significant influences on the intention to use UML.

  • Muscle atrophy, known as a sarcopenia, is defined as a loss of muscle mass resulting from a reduction in muscle fiber area or density due to a decrease in muscle protein synthesis and an increase in protein breakdown. Many conditions are associated with muscle atrophy, such as aging, denervation, disuse, starvation, severe injury and inflammation, prolonged bed rest, glucocorticoid treatment, sepsis, cancer, and other cachectic diseases. On the other hand, osteoarthritis (OA) is the most common form of joint disease and is wide spread in the elderly population and is characterized by erosion of articular cartilage, osteophyte formation, and subchondral bone sclerosis. The cytokine network plays an important role in the development and progression of OA with the inflammatory cytokine. Schisandrae Fructus (SF) derived from the ripe fruit of Schisandra chinensis (Turcz.) Baill. (Magnoliaceae) has been extensively used in traditional herbal medicines in Asia. It was originally used as a tonic and has been traditionally used for the treatment of many uncomfortable symptoms, such as cough, dyspnea, dysentery, insomnia, and amnesia for a long time. Previous reports have shown that SF and its related compounds possess various biological activities such as antioxidant, anti-inflammatory, anticancer, anti-microbial, antiseptic, anti-aging, hepatoprotective and immunostimulating effects. However, the therapeutic effects of SF on muscle atrophy and OA has not yet been evaluated. In the present study, we aimed to determine whether extracts of SF, the dried fruit of S. chinensis, mitigates the development of muscle atrophy and OA.

  • This study is conducted to investigate the current status on the utilization of health care and plan for solving this problem. The claims data of the fiscal tear 1995 obtained from the regional health insurance society are used for the study. The main findings of the study are summarized as follows. Indexes(The Extremal Quotient(EQ), coefficients of variance(CV's))which represent the regional difference in the admission rate of the tertiary medical diagnosis group report that there is difference in quantity and quality of utilization of health care. The admission rate is lower in the big city areas, Kyoungkido, Kangwondo and Chunlapukdo. Even after age-sex adjustment, the admission rate is still low in Kangwondo, Chunlapukdo and Kyoungsangpukdo. The big city areas tend to have higher rates in the expenses per claim, hospital days per claim, and daily expenses but the rates are still low in some area in Kangwondo, Chunlanamdo and Kyoungsangpukdo. This result remains as same after age-sex adjustment. There is a large regional difference in average utilization rate for the tertiary hospital of the tertiary medical diagnosis group: 57.2%(SD 11.53). The utilization rates for the tertiary hospital in their large catchment area are 96.34%, 83.19% and 73.22% in each Kyoungin, Kyoungnam and Kyoungpuk areas whereas it is lower in a Chungpuk and Chungnam areas. The regional differences of health care utilization of the tertiary medical diagnosis group gave some relationships with their geographical characteristics such as socio-economic characteristics and supply factors of medical services. It is important that many medical policies should be developed in order to minimize and balance out the regional differences of health care utilization. The service allocation policy should include the reconstruction of manpower policy, developing the resource allocating formula, finding the self-sufficient catchment area and reforcing of public health services. Moreover, in order to achieve the balanced development by region, they should investigate and consider each county's microscopic properties under the consistent macrocopic policy. The further studies to find causes of regional difference are needed.

  • Equity in health care has taken priority in the Korean government's policy agenda after the government-led national health insurance achieved universal coverage in 1989 along with the final inclusion of the self-employed as beneficiary. The purpose of this study is to examine the extent to which there exists difference or inequality in the utilization of health care, especially cancer inpatient services among income classes. We analysed the utilization of cancer inpatient services of residents in Jeju Island for a year of 2000, using the national health insurance data for qualification of beneficiaries and utilization of health care. The independent variable are 10 income classes based on the national health insurance fee imposed on each household for a year of 2000. The dependent variables of this study are an amount of cancer inpatient health care utilization measured by cancer admission days and cancer treatment costs. Also, cancer inpatient health care utilization is analysed by three categories divided into utilization in medical care institutions (1) within Jeju Island, (2) outside Jeju Island, and (3) all within and outside Jeju Island. We measured concentration index of cancer inpatient health care utilization. This analysis showed negative concentration index within Jeju Island and positive outside Jeju Island, and positive in all within and outside Jeju Island. This results suggest inequality against the relatively poor income groups in utilization of cancer inpatient health care services. Especially, inequity of cancer inpatient health care would be more serious in Jeju Island of Korea, considering that lower income groups reportedly have higher incidence rates in most of cancer and thus use more health services.

  • This study is an attempt to quantify rainwater utilization and miscellaneous water demand in Tokyo's 23 special wards, the core of the urban area in Tokyo, Japan, in order to elucidate the potential of further rainwater utilization. The rainwater utilization for miscellaneous appropriate water demands, including toilet flushing, air conditioning, and garden irrigation, were calculated for six different types of building: residential house, office, department store, supermarket, restaurant, and accommodation. Miscellaneous water demands in these different types of building were expressed in terms of equivalent rainfall of 767, 1,133, 3,318, 1,887, 16,574, and 2,227 (mm/yr), respectively, compared with 1,528 mm of Tokyo's average annual precipitation. Building types, numbers and its height were considered in this study area using geographic information system data to quantify miscellaneous water demands and the amount of rainwater utilization in each ward. Area precipitation-demand ratio was used to measure rainwater utilization potential for miscellaneous water demands. Office and commercial areas, such as Chiyoda ward, showed rainwater utilization potentials of <0.3, which was relatively low compared to those wards where many residential houses are located. This is attributed to the relatively high miscellaneous water demand. In light of rainwater utilization based on building level, the introduction of rainwater storage mechanisms with a storage depth of 50 mm for six different types of buildings was considered, and calculated as rainfall of 573, 679, 819, 766, 930, and 787 (mm), respectively. Total rainwater utilization using such storage facilities in each building from 23 wards resulted in the retention of 102,760,000 $m^3$ of water for use in miscellaneous applications annually, and this volume corresponded to 26.3% of annual miscellaneous water demand.

  • Purpose: This study examined change in healthcare utilization by disease severity after case management (CM) for Medicaid. Methods: Data were extracted from survey data on "Healthcare utilization and health status of Medicaid beneficiaries" conducted in 2007 and 2008 by the Ministry for Health, Welfare and Family Affairs. This study was designed to compare change in healthcare utilization between the CM group and the non-CM group. The subjects were 528 Type I Medicaid beneficiaries who utilized healthcare more than 365 days during 2006. Results: In beneficiaries having fewer than 3 among the 11 notified diseases, the CM group showed a significantly larger decrease in outpatient day, outpatient expense, medication day, and medication expense than the non-CM group. In beneficiaries having 3 or more among the 11 notified diseases, however, there was no significant difference in healthcare utilization between the CM group and the non-CM group. Conclusion: CM worked effectively on Medicaid beneficiaries outpatient healthcare utilization for mild diseases. However, its effects on hospitalization, which is a major cause increasing the total expense, were not observed. Therefore, a future study is needed to develope strategies to reduce hospitalization and care for Medicaid beneficiaries with severe diseases.
