The purpose of this study was to analyze characteristics such as spatial composition, areas, location of functional unit space and comparing the type and the number of operating programs by type of managements of multipurpose senior center in Youngnam metro area. first, the consignation management facilities had functional unit space of 152 things and the direct management facilities had 115 things. When comparing average areas composition ratio, direct management is public welfare, social education, public part, medical and rehabilitation order and consignation management is public part, social education, public welfare and rest part order. Second, medical part must be located around the first floor or the elevator, because many people can frequently use this area at the same time. Third, as a result of analysis of management programs indicated that the total number of programs is as a whole 74 things a range of $min12\~max20$ in the each direct management facilities and 111 things a range of $min20\~max24$ in the each in the each consignation management facilities. This fact shows that consignation management provided many people with more various programs than direct management. Finally, the number of staff in the direct management is less than consignation management. When comparing programs per staff and space, the direct and consignation management each appeared (2.74, 0.64) and (1.35, 0.73). This fact implied that the consignation management was more specialized than direct management in the service and function.

Purpose: The treatment of thyroid cancer patients was continuously increased. According to the increment of thyroid cancer patients, the establishment of iodine therapy site was also increased in each hospital. This treatment involves the administration of radioactive iodine, which will be given in the form of a capsule. Therefore, protections and managements for radioactive source pollution and radiation exposure should be necessary for radiation safety. Among the many problems, the problem of disposing the radioactive wastes was occurred. In this study, The date for self-disposal for radioactive wastes, which were contaminated in clothes, bedclothes and trash, were calculated. Materials and Methods: The number of iodine therapy ward was 15 in Korea Institute of Radiological Medical and Sciences. Recently, 8 therapy wards were operated for iodine therapy patients and others were on standby for emergency treatment ward of any radiation accidents. Radioactive wastes, which were occurred in therapy ward, were clothes, bedclothes, bath cover for patients washing water and food and drink which was leftover by patients. Each sample was hold into the marinelli beaker (clothes, bedclothes, bath covers) and 90 ml beaker (food, drink, and washing water). The activities of collected samples were measured by HpGe MCA device (Multi Channel Analysis, CANBERRA, USA) Results: The storage period for the each kind of radioactive wastes was calculated by equation of storage periods based on the measurement outcomes. The average storage period was 60 days for the case of clothes, and the maximum storage period was 93 days for patient bottoms. The average storage period and the maximum storage period for the trash were 69 days and 97 days, respectively. The leftover foods and drinks had short storage period (the average storage period was 25 days and maximum storage period was 39 days), compared with other wastes. Conclusion: The proper storage period for disposing the radioactive waste (clothes, bedclothes and bath cover) was 100 days by the regulation on self-disposal of radioactive waste. In addition, the storage period for disposing the liquid radioactive waste was 120 days. The current regulation for radioactive waste self-disposing was not suitable for the circumstances of each radioactive therapy facility. Therefore, it was necessary to reduce the leftover food and drinks by adequate table setting for patients, and improve the process and regulation for disposing the short-half life radioactive wastes.

본 연구에서는 국내산 50% 에탄올 복령추출물(KPE)과 중국산 50% 에탄올 복령추출물(CPE)의 약리활성 비교를 위하여 전 지방세포주인 3T3-L1 세포주와 암세포주인 Sarcoma 180 세포주를 이용하여 지방축적 억제활성과 항암활성을 비교하였다. 또한 노지재배 및 시설재배의 1년산 복령과 2년산 복령의 50% 에탄올 복령추출물(LPE, FPE)에 대해서도 50% 항암억제활성($IC_{50}$)로 중국산 복령과 비교하였다. 추가적으로 현재 시중에서 유통되고 CPE와 KPE의 안전성 자료를 획득하고자 단회 경구 독성시험을 실시하였다. CPE와 KPE를 3T3-L1 세포에 처리 후 48시간 이후에 대조군과 비교 시 지방축적 억제를 보였으나(p< 0.05), CPE와 KPE 사이에서는 지방축적 억제활성의 차이가 없었다. Sarcoma 180에 대한 CPE와 KPE의 항암활성을 비교할 때 시험한 농도에서 유사한 활성을 보였지만 $300{\mu}g/mL$의 고농도에서는 KPE가 CPE보다 높은 항암활성을 보였다(p < 0.05). 중국산 복령을 대체하고자 인공재배에서 생산된 노지재배 복령(LPE)과 시설재배 복령(FPE)의 항암활성 비교에서 CPE의 항암활성보다 높게 나타났다(p < 0.05). 단회 독성시험에서 CPE와 KPE의 $LD_{50}$(반수치사량)은 2,000 mg/kg 이상으로 추정되었다. 위의 결과를 종합 시 암세포주인 Sarcoma 180 세포주를 이용한 항암활성측정법은 중국산과 국내산의 원산지 검증의 생물활성검증의 보조수단으로 활용이 가능할 것으로 기대되었다. 국내에서 인공재배 되는 노지재배 복령 및 시설재배 복령은 중국산 복령을 대체하여 수입 감소의 효과를 기대할 수 있으며 지방축적 억제활성 및 항암활성의 기능성 원료로 활용이 가능할 것으로 생각되었다.
