Nausea, vomiting and retching are universal symptoms that affect individuals' state of health and self-care activities of individuals. Accurate measurements of individual symptoms are required to gather more definitive data, and enhance understanding, planning, and implementation of self-care actions. Recently the Rhodes Index of Nausea, Vomiting, and Retching(INVR), a new format of the INV-2(the Rhodes Index of Nausea and Vomiting), was developed to measure the symptoms of nausea, vomiting and retching in an English speaking population. To determine the reliability and validity of the INVR, and the possibility of using the instrument in Korea, the Korean translation of the INVR and the INV-2 were administered to a convenient sample of 105 patients at two University Hospitals in Kwangju, Korea. The Cronbach's alpha to estimate the internal consistency of reliability for INVR was 0.844. Equivalent measures of reliability were conducted to determine the percentage of agreement and the Spearman rank correlation coefficients for responses on the two instruments. The percent agreement was 83% and the correlation coefficient was 0.906 over all. A significant differences between the INVR scores of the patients with and without nausea, vomiting, or retching were seen, which indicated a construct validity. The INVR was found to be more user friendly for the patient and the healthcare providers. As a result, it is suggested that the INVR can provide a scientific base for measuring the symptoms of nausea, vomiting, and retching for nurses to improve patients' care and quality of life.

Background: With recent progress in health science administration, a huge amount of data has been collected from thousands of subjects. Statistical and computational techniques are very necessary to understand such data and to make valid scientific conclusions. The purpose of this paper was to develop a statistical probability model and to predict future survival times for male breast cancer patients who were diagnosed in the USA during 1973-2009. Materials and Methods: A random sample of 500 male patients was selected from the Surveillance Epidemiology and End Results (SEER) database. The survival times for the male patients were used to derive the statistical probability model. To measure the goodness of fit tests, the model building criterions: Akaike Information Criteria (AIC), Bayesian Information Criteria (BIC), and Deviance Information Criteria (DIC) were employed. A novel Bayesian method was used to derive the posterior density function for the parameters and the predictive inference for future survival times from the exponentiated Weibull model, assuming that the observed breast cancer survival data follow such type of model. The Markov chain Monte Carlo method was used to determine the inference for the parameters. Results: The summary results of certain demographic and socio-economic variables are reported. It was found that the exponentiated Weibull model fits the male survival data. Statistical inferences of the posterior parameters are presented. Mean predictive survival times, 95% predictive intervals, predictive skewness and kurtosis were obtained. Conclusions: The findings will hopefully be useful in treatment planning, healthcare resource allocation, and may motivate future research on breast cancer related survival issues.

Purpose: To develop the dose volume histogram (DVH) management software which guides the evaluation of radiotherapy (RT) plan of a new case according to the biological consequences of the DVHs from the previously treated patients. Materials and Methods: We determined the radiation pneumonitis (RP) as an biological response parameter in order to develop DVH management software. We retrospectively reviewed the medical records of lung cancer patients treated with curative 3-dimensional conformal radiation therapy (3D-CRT). The biological event was defined as RP of the Radiation Therapy Oncology Group (RTOG) grade III or more. Results: The DVH management software consisted of three parts (pre-existing DVH database, graphical tool, and $Pinnacle^3$ script). The pre-existing DVH data were retrieved from 128 patients. RP events were tagged to the specific DVH data through retrospective review of patients' medical records. The graphical tool was developed to present the complication histogram derived from the preexisting database (DVH and RP) and was implemented into the radiation treatment planning (RTP) system, $Pinnacle^3$ v8.0 (Phillips Healthcare). The software was designed for the pre-existing database to be updated easily by tagging the specific DVH data with the new incidence of RP events at the time of patients' follow-up. Conclusion: We developed the DVH management software as an effective tool to incorporate the phenomenological consequences derived from the pre-existing database in the evaluation of a new RT plan. It can be used not only for lung cancer patients but also for the other disease site with different toxicity parameters.

The Activity Based Costing(ABC) means the process that makes clear how the actions and input resources have changed into service to calculate medical services costs. These days, the number of hospital which is using the ABC system is increasing to make their policy decision making efficient and run the hospitals more resonable. This study analyzes the unbalance in the level of health insurance service fee and the improvement plans based from 8 hospitals(ABC system) and 95 clinics(ABC survey). The cost recovery ratio has shown different levels according to each service type. A surgery service type recorded 76.8% and an evaluation & management service type is 84.6%, a treatment procedure type(85.8%), a function test type(91.6%) and health insurance fee even did not reach to the original cost. Meanwhile, a laboratory test type and imaging test type show high level of cost recovery ratio. they recorded 188.3% and 158.8%. Resultingly now of unbalance in the level of health insurance service fee accelerates supply of every test. so there is a need to make laboratory test type and imaging test type lower to keep balance with the surgery and medical service. These methods should be performed gradually with monitoring the unbalance fee ratio and for this, a panel medical institution have to be established for generalizations of studying result, fairness of selecting researching sample.

Objectives: We investigated whether oriental medical therapy influences the results of in vitro fertilization-embryo transfer. Methods: 19 women with infertility were treated by oriental treatment from August 1999 to June 2000 in the department of obstetrics and gynecology of an oriental medical center. The women were planning in vitro fertilization-embryo transfer after oriental medicine treatment. The data from the women was analyzed, we obtained the following results. Results: The average age of infertile women was $35.42{\pm}4.86$; infertility caused by male factor or tubal factor were the most frequent. The average number of previous failed IVF treatments was $2.21{\pm}1.81$. The number of aspirated oocytes was $9.00{\pm}6.09$ in IVF cycle before oriental therapy, increasing to $9.80{\pm}5.41$ after therapy, but it was not statistically significant. In IVF before oriental therapy, the average number of embryos transfer was $3.20{\pm}1.90$, and it significantly increased to $4.40{\pm}1.45$ after treatment. The quality points of embryos were $10.00{\pm}6.02$ before treatment, but statistically significantly improved to $14.07{\pm}4.98$ after. The characteristics of women being pregnant and non-successful women were compared with age, period of taking herbal medicine and the number of failed IVF treatments, but there was no significant difference. Conclusion: Oriental treatment before IVF could be expected to have good results in treatment of infertility.

Recently, due to external environment like the changes in health policy and various healthcare accreditations, along with hospital's internal efforts to improve the quality of medical services, demands for the development of medical information systems are increasing. Some examples are clinical information like DUR (Drug Utilization Review), CVR (Critical Value Report), and automatic benefit processing by treatment purposes, or hospital DSS (Decision Support System) on overall medical practice. Such systems act as a guide in making clinic judgments during practice or in other medical practice, and their effects on the medical treatment improvements are being proven by previous studies. In the reality of increasing attention in the effects of medical treatment improvement, studies related to hospital DDS were mostly focused on clinical, technical, and engineering points of view, and studies focusing on the user viewpoint are very limited. In order to verify the effects of DSS on practice improvements and hospital's management performance, this study used a research model constructed to verify how SERVQUAL of hospital DSS affects hospital management performance in BSC (Balanced Score Card) point of view. To empirically verify the research model, a questionnaire was conducted on the basis of "K-University Hospital's DSS" on clinicians and hospital employees related to system development, and the relationships between the factors were analyzed through path analysis. As a result of path analysis, excluding reactivity, tangibility, confidence, reliability, empathy among service qualities, had partially significant effects on management performance factors (learning and growth, internal process, financial affairs). This study is to prepare the theoretical ground on the management performance analysis of hospital DSS, and suggest the service quality of the system that should be considered in the planning and development stages for improved system.
