Purpose : This study examined characteristics of, problems of and services provided to hospice recipients and their family members at a home hospice organization. Methods : The subjects were 113 people who were discharged from one free-standing home hospice organization between November, 1994 and lune, 1999. Since the opening of the organization in November of 1994, it has provided hospice services at patients' homes with no charge. Data were collected from those subjects' records. Results : The average age of the subjects was 57.1 years; those aged 60 and over were 54%. Spouse was the most frequent(50.9%) primary caregiver followed by daughter-in-law and daughter. All the subjects were diagnosed as having cancer. Of those 41 subjects who did not know their terminal stage in the beginning, 31 subjects came to know their states. Of the subjects, 72.7% were referred from their physicians. On the average, the service duration and the number of home visits were 6.8 weeks and 7.2 times, respectively. Pain was the most prevalent problem of the subjects(89.4%). Medication management was the most frequently provided service followed by psychological supports. The reasons for discharge were death(88.5%) and refusal(8%). Home was the most frequent place of death(60%). Conclusion Home hospice service providers should be trained particularly in working with elders and in managing cancer pain. People need to be referred at an appropriate time for achieving goals of hospice. Community recognition of hospice services needs to be promoted.

In this study, anthraquinone-2,7-disulfonic acid (2,7-AQDS) is used as negative active material and Tiron is used as positive active material for aqueous redox flow battery (RFB). In previous results that used the 2,7-AQDS and Tiron, sulfuric acid ($H_2SO_4$) was a supporting electrolyte. However, in this study, ammonium chloride ($NH_4Cl$) is suggested as the electrolyte for the first time. By changing the supporting electrolyte from $H_2SO_4$ to $NH_4Cl$, the cell voltage of RFB is improved from 0.76 V to 1.01 V. To investigate the effect of $NH_4Cl$ supporting electrolyte of the performance of RFB, the full-cell tests of RFB using 2,7-AQDS and Tiron that are dissolved in $NH_4Cl$ supporting electrolyte are carried out, while cut-off voltage range is a main parameter to determine their performance. When the cut-off voltage range is 0.2~1.6 V, the hydrogen evolution occurs during charging step. To address the side reaction effect, the cut-off voltage range is changed to 0.2~1.2 V. When the revised cut-off voltage range is used and the current density of $40mA/cm^2$ is applied, hydrogen evolution is not observed and the optimal RFB shows the charge efficiency of 99% and discharge capacity of 3.3 Ah/L at 10cycle.
