일본의 방사선의학총회연구소는 1957년에 설립되어, 금년으로 30주년을 맞이한다. 동 연구소에서는 방사선에 의한 암치료에도 크게 공헌해 왔다. 나아가 장래에 중립자선이라는 새로운 방사선을 사용한 획기적인 암치료의 계획이 구체화 되어 내년부터 시설의 건설이 시작될 예정이다.

매년 11만 명의 새로운 암환자가 발생하고, 이중 6만여 명이 암으로 사망을 하고 있음에도 정부나 사회, 심지어 의료인조차도 호스피스는 종교단체가 행하는 자선운동의 한 형태 정도로 바라보고 있는 것 같다.

The purpose of this study is to examine the factors influencing social performance of social entrepreneurship and Corporate Social Responsibility(CSR) activities. This model tests various theoretical research hypotheses relating to social enterprise, social entrepreneurship, and CSR activities. Social entrepreneurship have been classified as innovativeness, proactiveness, risk-taking, and social value orientation. And CSR activities have been classified as community responsibility, philanthropic responsibility, and environmental responsibility. The proposed model is analyzed to target social entrepreneurs. Valid 115 questionnaires have been collected within three months of 2013. Smart Partial Least Square(PLS) 2.0 have been utilized for deriving the study results. The result of hypothesis testing are as follows. First, social entrepreneurship positively influence community responsibility, philanthropic responsibility, and environmental responsibility. Second, community responsibility, philanthropic responsibility, and environmental responsibility positively influence social performance in social enterprise. The results of this study will provide various implications to improve social performance and social entrepreneurship in social enterprise.

This Study has been conducted to examine the transition of Japanese 'Social Welfare' in the light of Monthly Welfare which is the oldest professional journal of social welfare in Japan. Especially, this study has insisted on grasping the interaction among politics, economy, society, and culture through social historic perspective. Consequentially, some important themes are emerged from the journal which had been changed as time passes(Charity, Society and Relief, Social Work, Public Welfare Work, Social Work, and Monthly Welfare) as follows; 'strict declaration of charity and relief', 'relief work and social worker', 'professionalism and science of social work ', 'national life rebuilding and localization of welfare facilities', 'new face of livelihood protection and social work', 'community work and fund raising', and the like. In particular, it is revealed that 'Sahoisaup' is a word of translation from Social Work, in addition this word has been used as a word including diverse works in Japan. Also, it is emphasized that the necessity of Japanese experience could be studied in Korea.

Competing theories predict that others' contributions might be either substitutes or complements to one's own. Based on such competing theoretical discussions, this study attempted to examine the relationship between information about other citizens' giving behavior and citizens' giving. To achieve study objective, this study utilized a natural field experiment that investigates citizens' voluntary contributions to three types of kettle (transparent kettle with no money, transparent kettle with a large amount of bills and coinage, and red invisible kettle) during Salvation Army Red Kettle Campaign in 2011 and 2012. The experiment took place at subway stations which does not differences in the amount donated in previous years. In this field experiment, this study manipulated information about other citizens' giving behavior available to citizens by altering the different red kettle donation boxes. This study found that there are no positive or negative information effect on individual citizens' contributions. The results did not show either crowding-out effect or crowing-in effect. Thus, this study showed that social information has statistically non-significant impact on the propensity to donate and the amount donated.

Purpose Proton therapy can deliver an optimal dose to tumor while reducing unnecessary dose to normal tissue as compared the conventional photon therapy. As proton beams are irradiated into tissue, various positron emitters are produced via nuclear fragmentation reactions. These positron emitters could be used for the dose verification by using PET. However, the short half-life of the radioisotopes makes it hard to obtain the enough amounts of events. The aim of this study is to investigate the effect of off-line PET imaging scan time on the PET image quality. Materials and Methods The various diameters of spheres (D=37, 28, 22 mm) filled with distilled water were inserted in a 2001 IEC body phantom. Then proton beams (100 MU) were irradiated into the center of the each sphere using the wobbling technique with the gantry angle of $0^{\circ}$. The modulation widths of the spread out bragg peak were 16.4, 14.7 and 9.3 cm for the spheres of 37, 28 and 22 mm in diameters respectively. After 5 min of the proton irradiation, the PET images of the IEC body phantom were obtained for 50 min. The PET images with different time courses (0-10 min, 11-20 min, 21-30 min, 31-40 min and 41-50 min) were obtained by dividing the frame with a duration of 10 min. In order to evaluate the off-line PET image quality with the different time courses, the contrast-to-noise ratio (CNR) of the PET image calculated for each sphere. Results The CNRs of the sphere (D=37 mm) were 0.43, 0.42, 0.40, 0.31 and 0.21 for the time courses of 0-10 min, 11-20 min, 21-30 min, 31-40 min and 41-50 min respectively. The CNRs of the sphere (D=28 mm) were 0.36, 0.32, 0.27, 0.19 and 0.09 for the time courses of 0-10 min, 11-20 min, 21-30 min, 31-40 min and 41-50 min respectively. The CNR of 37 mm sphere was decreased rapidly after 30 min of the proton irradiation. In case of the spheres of 28 mm and 22 mm, the CNR was decreased drastically after 20 min of the irradiation. Conclusion The off-line PET imaging time is an important factor for the monitoring of the proton therapy. In case of the lesion diameter of 22 mm, the off-line PET image should be obtained within 25 min after the proton irradiation. When it comes to small size of tumor, the long PET imaging time will be beneficial for the proton therapy treatment monitoring.

Main research question of this study is based on situational gap between donation motivation and behaviour in non-profit organization. However, researches investigating the gap were limited. Therefore, this study examined components of psychological variables. Specially, we proposed the variables about consumer's impulsive motivation or behavior on impulse literature in donation toward non-profit organization. This study conducted a scale development to measure consumer's charity donation impulse based on non-conscious viewpoint. For the development of measurement tool for charity donation impulse, we conducted two stages of research process. First, the measurement items of charity donation impulse were developed through FGI and in-depth interview on experts. Secondly, the factor analysis was performed, and then some items were eliminated through this analysis. As a result, we found the final scale with 26 items, which were named as evaluation sensitivity charity impulse, reward sensitivity charity impulse, functional impulse, non-planning charity impulse. These results showed that the measurement items developed in this study were confirmed to be useful tools for measuring charity donation impulse.
