¹³¹I is a fission product produced in a nuclear reactor by irradiating tellurium dioxide, with a half-life of 8.02 day. The most important and widely used method for making ¹³¹I is irradiation using a nuclear reactor and post-irradiation followed by dry distillation. The advantage of the dry distillation process is that the process and the equipment are relatively simple, namely TeO₂ (m.p. 750 ℃), which can withstand heating during reactor irradiation. Based on TeO₂ irradiation by neutron following the technique of dry distillation was explained for production of ¹³¹I on a large scale. A dry distillation followed the radioisotope production operation using the 30 MW GA Siwabessy nuclear reactor to meet national demand. TeO₂ targets are 25 and 50 g irradiated for 87-100 h. The resulting ¹³¹I activity is 20.29339-368.50335GBq. According to the requirements imposed on the radionuclide purity of the preparation, the contribution of ¹³¹I training in the resulting preparation was not less than 99.9 %

There has recently been a growing demand for pathodiagnosis to determine the cause of death in cats. We retrospectively analyzed the diseases diagnosed in cats that were submitted to Animal and Plant Quarantine Agency (APQA) in 2015~2017. Overall diagnostic rate in feline samples was 85.2% (n=104/122). Among diagnosed cases, infectious diseases (n=63) were responsible for most of the feline diseases and feline panleukopenia (n=29) were most prevalent. Highly pathogenic avian influenza (HPAI) H5N6 was first diagnosed in cats at the end of December 2016 in the HPAI outbreaks. One case in 2015, 4 cases in 2016, and 14 cases in 2017 were associated with animal abuse, such as trauma and poisoning. These results suggest that suitable vaccination of feline infectious diseases, monitoring of the susceptible domestic animals during HPAI outbreaks, and interest on veterinary forensics to prevent and determine animal abuse are needed.

A stray female cat of unknown age, presenting bright red watery diarrhea, was submitted to the Animal and Plant Quarantine Agency for diagnosis. In the small intestines extracted from the necropsied cat, numerous white oval-shaped organisms were firmly embedded in the mucosa and there was thickening of intestinal wall. Histopathological analysis revealed severe necrotizing enteritis, together with atrophied intestinal villi, exfoliated enterocytes, and parasitic worms. Recovered worms were identified as Pharyngostomum cordatum by morphological observation and genetic analysis. Although P. cordatum is known to occur widely in Korea, this is the first clinical description of an infection by P. cordatum causing severe feline enteritis.

본 연구에서는 과학 교육 문헌에서 학생들의 실행에서 행위주체성의 어떠한 측면에 주목해왔으며 이를 학습 공동체를 구성하는 행위주체의 행위로서 어떻게 탐색해왔는지 검토하였다. 그 결과, 행위주체성이 크게 다섯 가지 측면에서 논의되었다는 점을 보였다. 행위주체로서 학생들의 실행은 인식적, 변화적, 실천적 측면에서 논의되었고, 행위주체인 학생들이 상호작용하는 학문 영역과 물질의 행위주체성 또한 논의되었음을 살펴보았다. 연구 결과에서 각 측면에 주목할 때 어떠한 구조적 특성을 지닌 활동 속에서 행위주체성을 어떻게 포착하고 논의하였는지 설명하였다. 이러한 논의를 바탕으로, 공동체를 구성하는 행위주체로서의 학생들의 실행을 각 문헌에서 구체적으로 어떻게 분석했는지 검토하였다. 그 결과를 학습 공동체 전반의 행위주체성에 주목한 경우, 초점을 맞춘 한 학생이 공동체의 활동 구조에 미치는 영향에 주목한 경우, 여러 학생들 사이의 상호작용에 주목한 경우로 구분하여 살펴보았다. 각 경우에 학습과 행위주체성을 해석한 관점과 그러한 연구가 지니는 시사점을 연구 결과에서 논의하였다. 본 연구는 학생들이 학습 공동체의 주체로서 역할을 하는 모습을 탐색하고 이를 지원하려는 노력에 기여할 것으로 기대된다.

The purpose of this study was to identify the degree of learned helplessness and self-care agency in dialysis patients and the relationship between learned helplessness and self-care agency. The subjects were 168 dialysis patients who were undergoing hemodialysis and peritoneal dialysis from 1 university hospital, 1 hospital, 1 hemodialysis center in Seoul, 1 hospital in Incheon, Korea. The data were collected with two interview questionnaires which were Learned Helplessness Scale (LHS) and Self-as-Carer Inventory (SCI). The collected data were analyzed by descriptive statistics and t-test, One-way ANOVA and Pearson Correlation with SPSSWIN program. Results were obtained as follows : 1) The mean scores of learned were 45.93(range 20-80). The mean learned helplessness scores of peritoneal dialysis patient and hemodialysis (HD) patient were not different significantly. However by the aging process, the mean scores of learned helplessness has a tendency to get higher and who had a job were likely to low score of learned helplessness. 2) The mean scores of self-care agency were 142.48 (range 33-198). The mean self-care agency scores of peritoneal dialysis (PD) patient much higher than the score of it with hemodialysis. The score of self-care agency were significantly different between peritoneal dialysis patient and hemodialysis patient. The patients who have job were likely to be higher score of self-care agency than other groups. 3) There was significant relationship between the score of learned helplessness and self-care agency. In conclusion, there was an inverse relationship between learned helplessness and self-care agency in dialysis patients. Considering this, the high level of learned helplessness of dialysis patients should be intervened by nurse with a well developed edicational program or cognitive behavioral therapy.

Ensuring sufficient supplies of clean, economic and acceptable energy is a critical global challenge for the 21st century. There seems little alternative to a greatly expanded role for nuclear power, but implementation of this option will depend on ensuring that all resulting wastes can be disposed of safely. Although there is a consensus on the fundamental feasibility of such disposal by experts in the field, concepts have to be developed to make them more practical to implement and, in particular, more acceptable to key stakeholders. By considering global trends and using illustrative examples from Japan, key areas for future R&D are identified and potential areas where the synergies of international collaboration would be beneficial are highlighted.
