As cost pressures have escalated, policy makers, politicians, health care providers and families have tried to devise ways to reduce health care costs. While originally developed to enhance patient control and to provide better care at the end of life, hospice care has recently received significant attention as a mean of reducing health care costs. As a program providing care for patients who are dying at their homes, hospice has expanded slowly since the opening of the first hospice in Korea in 1963. Therefore, a variety of services that responds to the needs and concerns of many dying people and their families is limited The purpose of this study was to determine the potential cost savings at the end of life among patients who used home hospice compared with the patients who received institutional care in Korea. This study used a retrospective, descriptive design. The sample for this study included 46 patients who died of lung cancer: 25 patients who received home hospice care and 21 patients who received institutional care. Data on patient characteristics, kinds and frequencies of provided treatment and nursing services, and hospice and hospital charges during the last month before death were collected. Cost of care was measured by the average cost per patient per day in the last month of life. The results of the study indicated that there were significant differences in average cost of care between home hospice sample and institutional care sample (t=9.956, p<.001; home hospice sample: M=18,102 won, institutional care sample: M=317,578 won). The cost of the home hospice sample was approximately 6% of the cost of institutional care. The majority of the home hospice nursing services were education (35.7%) and supportive counseling (25.2%), followed by medication management (13.6%), assessment (12.1%), basic nursing (7.2%), treatment (5.5%) and others. In institutional care sample, basic nursing and treatment were more emphasized than education or supportive counseling among the nursing services provided. The results of this study showed the potential for hospice to reduce costs and implications for policymakers and clinicians to incorporate hospice program into the formal health care delivery system in Korea.

Perchlorate ion($ClO_4^-$), which is present in the solid propellant for rocket, herbicide and some fertilizers. Perchlorate inhibits iodide uptake by the human thyroid gland. Impairment of thyroid function in expectant mothers may impact the fetus and result in effects including cerebral palsy, give rise to thyroid gland cancer. The US EPA(Environmental Protection Agency) adopted a reference dose(RfD) for perchlorate 0.0007 mg/kg-day, and this guidance lead to a Drinking Water Equivalent Level(DWEL) of 24.5 ${\mu}g/L$. The studies about perchlorate are actively performed in foreign countries, especially in USA but there is no study which surveyed the perchlorate contamination in Korea. Therefore, this study was done to investigate perchlorate contamination in Nak-dong river and tap water. The perchlorate was detected in Nakdong river and ranged from ND to 278.4 ${\mu}g/L$. The highest concentration was observed in Kumichon. The perchlorate concentration was decreased with the down stream of Nakdong river. The perchlorate concentration in tap water was varied with the cities and the concentration levels were $ND{\sim}34.1$ ppb. The highest perchlorate concentration was observed in DalsuGoo in Daegu and the similar concentration($9{\sim}11$ ${\mu}g/L$) was detected in most of the districts in Busan. The result of this study suggests that there is a perchlorate source near the Nakdong river and the urgent policy is needed to control perchlorate for the cities which are supplied from Nakdong river as for their tap water.

Purpose : First of all, this study was performed to assess the result of curative radiotherapy and to evaluate different possible prognostic factors for squamous cell carcinoma of the supraglottic larynx treated at the Pusan National University Hospital. The second goal of this study was by comparing our data with those of other study groups, to determine the better treatment policy of supraglottic cancer in future. Methods and Material : Thirty-two patients with squamous cell carcinoma of the supraglottic larynx were treated with radiotherapy at Pusan National University Hospital, from August 1985 to December 1996. Minimum follow-up period was 29 months, Twenty-seven patients (84.4$\%$) were followed up over 5 years. Radiotherapy was delivered with 6 MV photons to the primary laryngeal tumor and regional iymphatics with shrinking field technique. Ail patients received radiotherapy under conventional fractionated schedule (once a day). Median total tumor dose was 70.2 Gy (range, 55.8 to 75.6 Gy) on primary or gross tumor lesion. Thirteen patients had Induction chemotherapy with cisplatln and 5-fluorouracil (1-3 cycles). Patient distribution, according to the different stages, were as follows: stage I, 5/32 (15.6$\%$): stage II, 10/32 (31.3$\%$); stage III, 8/32 (25$\%$): stage IV, 9/32 (28.1$\%$). Results :The 5-year overall survival rate of the whole series (32 patients) was 51.7$\%$. The overall survival rate at 5-years was 80$\%$ in stage I, 66.7$\%$ in stage II, 42.9$\%$ in stage III, 25$\%$ in stage IV (p=0.0958). The S-year local control rates after radiotherapy were as fellows: stage I, 100$\%$; stage II, 60$\%$ stage III, 62.5$\%$; stage IV, 44.4$\%$ (p=0.233). Overall vocal preservation rates was 65.6$\%$, 100% In stage I, 70% in stage II, 62.5$\%$ In stage III, 44.4$\%$ in stage IV (p=0.210). There was no statistical significance in survival and local control rate between neoadjuvant chemotherapy followed by radiotherapy group and radiotherapy alone group. Severe laryngeal edema was found in 2 cases after radiotllerapy, emergent tracheostomy was done. Four patients were died from distant metastsis, . three in lung, one in brain. Double primary tumor was found in 2 cases, one in lung (metachronous), another in thyroid (synchronous). Ulcerative lesions were revealed as unfavorable prognostic factor ( p=0.0215), and radiation dose (more or less than 70.2 Gy) was an important factor on survival (p=0.002). Conclusion : The role of radiotherapy treatment of supraglottic carcinoma is to important factor on survival and to preserve the laryngeal function. Based on our data and other studies, early and moderately advanced supragiottic carcinomas could be successfully treated with either consewative surgery or radiotherapy alone. Both modalities showed similar results in survival and vocal preservation. For the advanced cases, radiotherapy alone is Inadequate for curative aim and surgery combined with radiotherapy should be done in operable patients. When patients refuse operation or want to preserve vocal function, or for the patients with inoperable medical conditions, combined chemoradiotherapy (concurrent) or altered fractionated radiotherapy with or without radiosensitizer should be taken into consideration in future.

Owing to causes such as population aging, increased use of various medical devices, long-term hospitalization of various patients with reduced immune function such as cancer, diabetes, and organ transplant patients, and the growing size of hospitals, hospital infections are continuing to increase. As seen in the MERS crisis of 2015, hospital infections have become a social and national problem. In order to prevent damage due to such hospital infections, it is necessary to first strictly implement measures to prevent hospital infections, while, on the other hand, providing proper relief of damage suffered due to hospital infections. However, the mainstream attitude of judicial precedents relating to hospital infection cases has been judged to in fact shift responsibility over damages due to hospital infections on the patient. In light of the philosophy of the damage compensation system, whose guiding principle if the fair and proper apportionment of damages, there is a need to seek means of drastically relaxing the burden of proof on the patient's side relative to conventional legal principles for relaxing the burden of proof, or the theory of de facto estimation. In relation to such need, the German civil code (Burgerliches Gesetzbuch), which defines contracts of medical treatment as typical contracts under the civil code, and has presumption of negligence provisions stipulating that, in cases such as hospital infections which were completely under the control of the medical care providers, if risks in general medical treatment have been realized which cause violations of the life, body, or health of patients, error on the part of the person providing medical care is presumed, was examined. Contracts of medical treatment are entered into very frequently and broadly in the everyday lives of the general public, with various disputes owing thereto arising. Therefore, it is necessary to, by defining contracts of medical treatment as typical contracts under the civil code, regulate the content of said contracts, as well as the proof of burden when disputes arise. If stipulations in the civil code are premature as of yet, an option may be to regulate through a special act, as is the case with France. In the case of hospital infection cases, it is thought that 'legal presumption of negligence' relating to 'negligence in the occurrence of hospital infections,' which will create a state close to equality of arms, will aid the resolution of the realistic issue of the de facto impossibility of remedying damages occurring due to negligence in the process of occurrence of hospital infections. Also, even if negligence is presumed by law, as the patient side is burdened with proving the causal relationships, such drastic confusion as would occur if the medical care provider side is found fully liable if a hospital infection occurs may be avoided. It is thought that, alongside such efforts, social insurance policy must be improved so as to cover the expenses of medical institutions having strictly implemented efforts to prevent hospital infections in the event that they have suffered damages due to a hospital infection accident, and that close future research and examination into this matter will be required.

Objectives: This study was aimed at investigating the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors. And we want to compare the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors among the provinces. Methods: In order to compare, the data was referred to National health insurance center for affirming the insurance type of the dead. And age adjusted mortality rate of tuberculosis of each insurance type was analyzed by whole country and the provinces. Related factors of the provinces were gathered from public statistic books. We analysed correlation study between the ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis and related factors among the provinces. Results: Major findings were as follows 1. The ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis was 5.6. And the ratio was relatively high at 40-60 ages. 2. The ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis by the province was varying. And the factors that were financial independence, crowdedness, percent of people on medical aid, population size served by each public health center, number of hospital by a million peoples have correlated with increment of the ratio. Conclusions: As a consequence of tuberculosis control, the ratio was high. Thus this finding suggests that medical utilization and preventive behavior, environment of tuberculosis patient are under handicapped condition. Especially large cities like metropolitan area who have high financial independence, high population density, high percentage of medical aid peoples have high ratio of medical aid over health insurance of age adjusted mortality rate of tuberculosis. There is need for additional and systematic research on the attitude or tendency toward medical services(inc1uding preventive services) utilization of medical aid tuberculosis patients.
