The purpose of this presentation is to outline the measurement made at Korea Cancer Center Hospital, KAERI, and to present the result obtained. These measurements were designed to demonstrate the complicance of the isocentric fast neutron facility. 1. Neutron production and delivary. 2. Physical parameters of the neutron beam. 3. Neutron beam calibration including 'n' ratio and detector design. 4. Treatment planning. 5. Health physics consideration etc. will be covered the above topics.

Purpose: This study investigated the level of Activities of Daily Living (ADL) of elderly patients with pulmonary disease preparing for discharge and the factors affecting it. Methods: The participants of this cross-sectional, descriptive study were 104 patients aged over 65 diagnosed with pulmonary disease at an acute care hospital. Data were collected from November 28, 2018 to March 15, 2019 using a structured questionnaire and the participants’ electronic medical record. The questionnaire asked about demographic and disease-related characteristics and respiratory symptoms experience, and included the Korean versions of the ENRICHD Social Support Instrument, Hospital Anxiety and Depression Scale, and Katz’s ADL. Results: In the enter-method multiple linear regression analysis, the model explained 38.1% of the ADL (F=4.26, p<.001). The higher the participants’level of depression, the lower their level of ADL (β=0.43, p<.001), while those without a history of any neurological or psychiatric disease had higher levels of ADL than their counterparts with it (β=-0.22, p=.024). Conclusion: The findings suggest that an intervention that considers depression and history of neurological or psychiatric disease should be implemented to promote ADL among elderly patients with pulmonary disease preparing for discharge. In addition, the results of this study can be used as fundamental information to assess the discharge readiness of elderly patients with pulmonary disease and improve their health-related quality of life by promoting ADL.

Trillions of microorganisms reside in the hosts' gut. Since diverse activities of gut microbiota affect the hosts' health status, maintenance of gut microbiota is important for maintaining human health. Green tea (GT) has multiple beneficial effects on energy metabolism with antiobesity, antidiabetic, and hypolipidemic properties. As GT contains a large amount of bioactive ingredients (e.g., catechins), which can be metabolized by microorganisms, it would be feasible that consumption of GT may cause compositional changes in gut microbiota, and that the changes in gut microbiota would be associated with the beneficial effects of GT. In this study, we demonstrated that consumption of GT extract relieves high-fat diet-induced metabolic abnormalities. Interestingly, GT administration significantly encouraged the growth of Akkermansia muciniphila (Akkermansia), a beneficial microorganism to relieve obesity and related metabolic disorders. Finally, we found that epigallocatechin gallate is the component of GT that stimulates the growth of Akkermansia. According to these data, we propose that GT could be a prebiotic agent for Akkermansia to treat metabolic syndromes.
