양성자가속기는 재료산업, 반도체산업, 생명산업, 등 다양한 산업에 폭 넓게 이용되고 있다. 양성자가속기의 이용 분야에서 양성자 요법도 빼놓을 수 없는 중요한 분야이다. 양성자가속기의 제어 소프트웨어는 일반적으로 EPICS라는 개발 도구를 이용하여 개발하는데 반하여 양성자 요법에서는 제어시스템으로 IBA에서 개발된 PTS(Proton Therapy System)이 사용된다. 대형 양성자 가속기는 산업용과 의료용으로 다양하게 사용될 수 있으므로 EPICS로 개발된 제어소프트웨어와 IBA의 PTS가 호환성이 있든지 아니면 의료용의 양성자 요법 시스템용 제어소프트웨어까지 EPICS로 개발할 필요가 있다. 본 논문은 EPICS로 양성자 요법 시스템의 제어소프트웨어의 사용자 인터페이스를 구현한 결과를 소개한다.

Purpose: This study was undertaken to evaluate the clinical usefulness of Tensilon test, repetitive nerve stimulation test(RNST), single fiber EMG(SFEMG) test and acetylcholine receptor antibody(AchR Ab) assay for making diagnosis of myasthenia gravis(MG). Method: These tests were performed in 21 MG patients which were classified into 11 ocular, 5 mild generalized, 4 moderate generalized, and 1 chronic severe MG. Result: The overall positivity of Tensilon test, SFEMG and AchR Ab was 95%, 87%, and 76% respectively. The overall positivity of RNST was 67%; 38% on flexor carpi ulnaris, 43% on adductor digiti quinti and 62% on orbicularis oculi muscles. The positivity of each test was higher in generalized MG group than in ocular MG group. But we could observe the statistically significant difference only in the RNST(p<0.05). Conclusion: Tensilon test showed the highest positivity in all MG groups. So we would like to recommend the, Tensilon test for the diagnosis of MG at first, followed by RNST and AchR Ab assay, and SFEMG would be indicated to MG group which showed relatively low postivity in other tests.

This study examines the characteristics of teacher education system and professional standards of teachers in Canada through analysis of the current teacher education curriculum and salary grids of teachers in Canada. As a result, the following characteristics were found. First, contents and theories acquired during the course of teacher education are connected to the actual practice to increase the site-compatibility. Second, professional standards of teachers is rather holistic, than detailed and systematic. Based on the findings, the following implication can be drawn. To enhance the site compatibility of teachers in the Republic of Korea, it is requisite to build a persistent, and cooperative relationship among the faculty members of teacher education program, the members of the community, and supervisor teachers of practicum schools. Also, it is necessary to come up with a system that directly connects the professionalism of the teachers and the salary grids, as the salary of teachers are adjusted according to the completion of degree or courses, reflecting the professionalism.

Science teachers' perception on their preparation program can help in conceptualizing how science teachers could be prepared. Based on this premise, this study aims to investigate preservice and inservice science teachers' perception on their teacher preparation programs with a focus on the coherence and balance of program. For this purpose, 20 preservice and 39 inservice science teachers were participated. Selection form and open-ended form questionnaires were developed to survey science teachers' perception on their program. The results of study are as follows: Firstly, participating preservice and inservice science teachers perceived the coherence of their program as moderate. The most and least coherent category of program was 'planning & preparation' and 'professional responsibilities' respectively. Inservice teachers perceived the program less coherent than preservice teachers in all four categories. Secondly, participating preservice and inservice science teachers perceived that practical elements were deficient compare to theoretical elements in light of balance of the program. Lastly, participating preservice and inservice science teachers perceived that current science teacher preparation program was biased to test-driven curriculum, and four domains of the program (subject matter knowledge, pedagogical content knowledge, general pedagogical knowledge, and teaching practicum) need to be more strongly connected to secondary school context. Alternative ways to be more coherent and balanced science teacher preparation program were also discussed based on the research.

나노기술, 정보통신기술, 바이오 기술 등을 중심으로 기술융합이 급속히 진행되는 가운데, 이러한 변화에 대응할 수 있는 인력 양성의 필요가 제기되고 있다. 이에 대하여, 본고에서는 지식형성측면을 중심으로, 이러한 융합기술의 확산에 대응한 융합인력양성의 방향성을 제시하고자 한다. 융합기술에 대응한 인력양성 및 활용을 위해서는, 융합기술의 진행에서 지식의 속성이 어떠한 변화를 가지는지, 또한 특정한 속성의 변화가 존재한다면 새로운 속성을 포함한 지식의 생성과 습득은 어떠한 과정을 통해 달성될 수 있는지가 규명되어야 할 것이다. 본고는 IT기반 의공학부문과 양자암호체계에서의 융합연구 사례를 통해, 기술 성격과 지식 습득 전략을 검토하고, 이들 융합기술 수행과정상의 특징으로 부터 인력양성에 대한 함의를 얻고자 한다.

제지산업의 발전에 따라 치환도가 다른 여러 가지 용도의 양성 전분이 개발되어 적 용되고 있다. 특히 보류제로서 양성전분을 사용할 경우 보류 향상과 더불어 강도개선 효과를 동시에 얻을 수 있는 이점을 지니고 었다. 하지만 용수 조건의 악화, 미세분 함 량의 증가 등과 같은 점차 열악해지는 초지공정에 적용하기 위해서는 보다 높은 치환 도의 전분이 요구 되고 있다. 이에 본 연구에서는 고치환 양성 전분이 초지계 내에 첨가되었올 경우 나타나는 홉 착 특성을 파악하고, 보류 및 탈수 성능을 평가함으로서 올바른 적용 방법을 제시하고 적용 효율의 극대화를 모색하고자 하였다. 산-염기 세척과정을 거쳐 제조한 활엽수 BKP를 이용해 지료를 조성하고, DDA

This study was conducted to evaluate the clinical effectiveness of proton therapy as an advanced convergent cancer therapy. Clinical data of proton therapy were analyzed. As proton enters patient's body, it releases low dose of energy and shows an increasing energy deposition as it reaches certain point unlike x-ray. It may therefore reduce the radiation dose to the normal tissues in front and beyond the lesion and minimize the radiation damage. Proton therapy is expected to improve clinical outcomes and reduce treatment related toxicities. It is used in various cancers. Further studies are necessary.

Purpose To investigate the incidence of tuberculosis (TB) in healthcare workers (HCWs) with positive interferon-gamma release assay (IGRA) results based on chest X-ray (CXR) and CT findings and determine the role of imaging in the diagnosis of TB. Materials and Methods Among 1976 hospital personnel screened for TB using IGRA, IGRApositive subjects were retrospectively investigated. Clustered nodular and/or linear streaky opacities in the upper lung zone were considered positive on CXR. The CT findings were classified as active, indeterminate, inactive, or normal. The active or indeterminate class was considered CT-positive. Results IGRA was positive in 255 subjects (12.9%). CXR and CT were performed in 249 (99.2%) and 113 subjects (45.0%), respectively. CXR- and CT-positive findings were found in 7 of 249 (2.8%) and 9 of 113 (8.0%) patients, respectively. Among the nine CT-positive subjects, active and indeterminate TB findings were found in 6 (5.3%) and 3 (2.7%) patients, respectively. Microbiological tests, including acid-fast bacilli staining, culture, and polymerase chain reaction for TB, were negative in all nine CT-positive subjects. Empirical anti-TB medications were administered to 9 CT-positive subjects, and 3 of these nine subjects were CXR-negative for pulmonary TB.
