Sound scattering in 3D complex geometry is difficult to model with body-fitted grid. Thus Brinkman Penalization method is used to compute sound scattering in 3D complex geometry. Sound propagation of monitor/TV is studied. The sound field for monitor/TV is simulated by applying Brinkman Penalization method to Linearized Euler Equation. Solid Structure and ambient air are represented as penalty terms in Linearized Euler Equation.

Warfarin is an anticoagulant for preventing thromboembolic disorder. Because of it's narrow therapeutic range and adverse effect such as bleeding or thromboembolism, we should monitor patient closely. The patients must be educated various drug-drug and drug-food interaction. We investigated patient's awareness and the rate of adverse effect for warfarin therapy. This study was conducted through retrospective chart review and questionnaire of fifty outpatients who received warfarin sodium for at least three months from July to September 1998. As s result, forty one patients(82%) have known about disease. The awareness of pharmacological effect and adverse effect was 48% and 52%, respectively. The awareness of drug-drug and drug-food interaction was 6% and 0%, respectively. Thirty two patients(64%) experienced bleeding complication. Among the patients, twenty nine patients experienced minor bleeding such as bruise, delayed hemostatis, gingival bleeding, epistaxis, hemoptysis, bloody stool. And three patients visited hospital because of GI bleeding, intracranial bleeding or severe epistaxis. Two patients(4%) experienced thromboembolic complication such as stroke or pulmonary embolism. The percentage of the patients maintained unstable and subtherapeutic International Normalized Ratio(INR) was 28% and 48%. respectively. The rate of bleeding complication of the patients maintained stable and unstable INR was 25% and 93%, respectively. In this research, we found that the patient's awareness was low and more adverse effects occurred in the patient with unstable INR. We concluded that medical team educate patient continuously and adjust dosage regimen for Warfarin therapy. Pharmacist-managed Anticoagulation Service(ACS) may provide to improve the quality and end ensure the continuity of patient care.

Purpose: The purpose of this study was to know relationship between Sex Life Satisfaction and Depression of the Elderly, provide fundamental information of a sex related nursing intervention health promotion program in order to decrease depression and improve the quality of life for the elderly. Method: The subjects were collected by convenient sampling comprised of 113 elderly. The instruments used for this study were the Hwang’s sex life satisfaction measuring instrument to evaluate sex life satisfaction, the K-GDS(Korean Form of Geriatric Depression Scale) to evaluate depression. Result: The general factors effecting the sex life satisfaction of the elderly were as follows: Religion, Subjective financial condition. The general factors effecting depression were as follows: Personal relationship. Among the characteristics of the sexually active subjects’ sex lives, ‘How often do you enjoy your sexual life’ affected depression. As a result of analyzing Pearson’s product moment correlation coefficient in order to figure out the elderly’s perception of the relationship between the level of depression and sex life satisfaction, it showed that there was a statistically significant inverse relationship(p-value of 0.01). Conclusion: This study revealed that the relationship between Sex Life Satisfaction and Depression of Elderly were inversely related with statistical significance. Especially, the all-round quality of life that the elderly subjectively feel was an important factor affecting their sex life satisfaction and depression. Therefore, there should be an institutional improvement for advancement of the level of economic status and health, and a development or practice of program for personal relationships.
