This study explored demographic characteristics based everyday lifestyle patterns and preferred spatial requirements of potential collective housing residents in Korea who would pursue ‘Ambient Assisted Living’ with ‘Aging In Place’ initiatives. Online questionnaire survey was commissioned for the pre-elderly and elderly age groups of 40s, 50s and above 60s, 801 individuals in total. Survey participants were asked to select 3 most preferred answers among 5 with ranked priority to clearly capture each testee’s true priority choices over 50 carefully designed questions in relation with promoting healthcare sensitive residential spaces. Comprehensive analysis was carried out by processing the survey results with cross-tabulation analysis. The outcome showed fairy unanimous preference patterns across majority of the questions regardless of gender, age, and economic status differences. Formation of separate and independent household, relatively spacious living room, possible layout alteration after moving into a residence, non-slippery bathroom floor, bio-medic sensor embedded chair or sofa were identified as those commonly preferred requirements of physical space design for an household. Some subject groups such as female and age group of over 60s show similar preference profile in the sense that both groups prefer living in the same collective residence when they are aged, cooking ordor ventilating kitchen, bed with storage below, ventilation for kitchen and bathroom. This implies certain demographic groups share their residential preference when aging is in progress. Differentiated residential preference profiles among different demographic groups were also identified. For instance, male, age groups of 50s and over 60s, low-income group prefer living in a same household whereas female, age group of 40s and high-income group turn out to prefer living in a separate household in the same collective housing complex when they are aged. While most of testees prefer garden farming for their apartment veranda, age group of 40s and high-income group express their preference of using veranda as a resting place. Comprehensive analysis on those preference profiles across major demographic classification was summarized in table format focused on healthcare sensitive household unit design. This study is a pioneering attempt to identify a set of preferred health-sensitive lifestyles and residential space requirements to be insightful for planning and designing ‘active aging in place’ supportive collective housing household units in Korean context.

갑상선 진료환자 관련 방사성폐기물의 처분을 위한 방사능 측정 및 평가

김창범(Chang-Bum Kim),장성주(Seong-Joo Jang) 한국콘텐츠학회 2014 한국콘텐츠학회논문지 Vol.14 No.6

의료현장에서의 방사성폐기물은 방사성동위원소의 사용량의 증가와 더불어 급격히 늘어나고 있다. 특히, 갑상선 질병의 진단 및 치료용으로 사용량이 증가하고 있는 I-131 핵종의 경우 8.02 일의 짧은 반감기를 가지고 있으며, 관련 폐기물은 모두 자체처분 방법으로 처분하고 있다. 이와 관련하여 국제원자력기구(IAEA)는 개인선량(10 μSv/y) 및 집단선량(1 man-Sv/y)과 핵종별 농도에 근거하여 각각 폐기물의 규제해제기준을 제시(IAEA Safety Series No 111-P-1.1, 1992 및 IAEA RS-G-1.7, 2004)하였다. 이 연구에서는 의료현장에서 발생하는 I-131 핵종 관련 폐기물을 사용상 종류별로 수집 및 측정하여 방사능농도의 측정 방법 및 절차를 수립한다. 또한, 측정 결과를 바탕으로 핵종의 감쇠 유도식을 산출하고, 이것을 바탕으로 자체처분 가능일자를 산출하여 이론식의 경우와 대비하여 고찰하였다. 측정 결과를 바탕으로 유도 감쇠식을 신정하여 이론적 반감기와 유효 반감기를 비교해 본 결과, I-131 핵종의 이론적 반감기가 유효반감기(7.72일)에 비해 긴 반감기를 가지고 있음을 확인하였다. 측정결과를 바탕으로 한 유효 반감기를 적용한다면, 현재보다 더 짧은 기간 동안 I-131 핵종 폐기물을 보관하였다가 자체처분을 할 수 있다. 이 연구 결과는 ISO 표준으로 추진할 예정이다. The generation amount of radioactive waste has been rapidly increased by increase of the usage of radioisotope source in medical field. Especially, the use of the radioactive source of I-131 with short half-life of 8.02 days used in treatment of thyroid has been increased, and all of the wastes concerned have been disposed by means of the self-disposal method. IAEA proposed criteria for clearance level of waste which depends on the individual (10 μSv/y) and collective dose (1 man-Sv/y), and concentration of each nuclide (IAEA Safety Series No 111-P-1.1, 1992 and IAEA RS-G-1.7, 2004). In this study, various radioactive wastes in medical fields are collected and measured for establishing the disposal methods and procedures of radioactive wastes. In addition, comparison evaluation of decay storage period between the half-life which was calculated by attenuation curve based on real measurement and analytical half-life is considered. With comparing the theoretical half-life and the effective half life(7.72 days) which was based on the decay equation of measured data, it is resulted in the theoretical half-life is longer than effective half-life. The storage period of radioactive waste for self-disposal may be curtailed. The result of this study will be proposed as ISO standard.

의료용 Re-186 오염폐기물의 규제해제를 위한 방사능측정

김창범(Kim Chang-Bum),이상경(Lee Sang-Kyung),장성주(Jang Seong-Joo),김정민(Kim Jung-Min) 대한방사선과학회(구 대한방사선기술학회) 2017 방사선기술과학 Vol.40 No.4

방사선 진료기술의 발전에 따라 의료분야에서 발생하는 방사성폐기물이 급속히 증가하고 있다. 최근의 경향을 보면, 갑상선암 진료 목적의 I-131을 비롯하여 PET/CT 조영제로 사용하는 F-18, 핵의학검사에 폭 넓게 적용하는 Tc-99m 등의 방사성동위원소 사용이 일반화 되고 있다. 사용과정에서 이러한 핵종에 오염된 방사성폐기물이 발생하게 되는데, 일정기간 보관한 후에 방사능이 규제해제(Clearance) 수준으로 감쇠하면 소각 등의 방법으로 자체처분하게 된다. 국제원자력기구(IAEA)에서는 10μSv/y의 개인선량 및 1man-Sv/y의 집단선량과 함께 핵종별 농도에 근거하여 방사성폐기물의 규제해제기준을 제시하였다. 이 연구에서는 IAEA의 핵종별 방사능농도기준에 따른 규제해제 시점을 확인하기 위하여, Tc-99m과 방사화학상 유사한 성질을 가지고 있는 Re-186 관련 방사성폐기물을 수집하여 방사능을 측정하였다. Re-186은 반감기가 3.8일 로 방사성의약품으로는 비교적 길고, 베타선 및 감마선을 방출하여 방사성의약품 치료와 영상에 모두 사용된다. Re-186 사용과 관련하여 발생하는 오염된 일회용장갑(Poly Glove)의 방사능측정을 위하여 다중파고분석기(Multi Channel Analyzer; MCA)를 이용하였으며, 이를 위하여 표준물질을 제작하여 MCA를 교정한 이후 감마방사능 측정 절차에 따라 수행하였다. 측정결과를 근거로 방사능 감쇠 유도식을 산출하여 이론식과 대비하여 고찰하였는바, Re-186 핵종의 유도반감기(3.6일)는 이론적 반감기(3.8일)에 비해 다소 짧은 것으로 나타났다. 따라서 측정결과에 근거한 유도반감기를 적용한다면, 다소 줄어든 기간 동안 Re-186 핵종 폐기물을 보관하였다가 자체처분을 할 수 있을 것으로 확인하였다. 이 연구 결과는 현재 추진하고 있는 국제표준화기구(International Organization for Standardization) 국제표준에 포함될 예정이다. The amount of radioactive waste has been rapidly increased with development of radiation treatment in medical field. Recently, it has been a common practice to use I-131 for thyroid cancer, F-18 for PET/CT and Tc-99m for diagnosis of nuclear medicine. All the wastes concerned have been disposed of by means of the self-disposal method, for example in-cineration, after storage enough to decay less than clearance level. IAEA proposed criteria for clearance level of waste which depends on the individual (10 μSv/y) and collective dose (1 man-Sv/y), and concen-tration of each nuclide (IAEA Safety Series No 111-P-1.1, 1992 and IAEA RS-G-1.7, 2004). In this study, specific radioactivity of radioactive waste contaminated with Re-186 was measured to con-firm whether it meets the clearance level. Re-186 has long half life of 3.8 days relatively and emits beta and gamma radiation, therefore it can be applied in treatment and imaging purposes. The specific radioactivity of contaminated gloves weared by radiation workers was measured by MCA(Multi-channel Analyzer) which was calibrated by reference materials in accordance with the measuring procedure. As a result, comparison evaluation of decay storage period between the half-life which was calculated by attenuation curve based on real measurement and physical half-life was considered, and it is showed that the physical half-life is longer than induced half-life. Therefore, the storage period of radioactive waste for self-disposal may be curtailed in case of application of induced half-life. The result of this study will be proposed as ISO standard.

The curve of a roof is one of the distinctive external characteristics in traditional buildings of three far-eastern countries. Nevertheless, it has not been easy to identify and classify various roof styles. With the advance of culture technology, it becomes necessary to devise a mathematical method how to methodologically characterize the roof curve of traditional buildings. In this context, we explored, through differential geometric techniques, how a roof curve could be formulated by a discrete curvature. Discrete real data is corrected by numerical analytic method and discrete curvature is computed. The outcome of the research could be used to systematically describe and categorize roof curves to regenerate them in cyber world primarily for 3D rendering or animation of traditional oriental buildings.
