There are 4 types of equipment in diagnostic radiography. These are single phase, three phase, inverter type and condenser type X-ray generators. It is very confusing to make an adequate exposure factor and to know the usage of different type of X-ray generators. In this experiment, I explored a comparative study of outputs in 4 different type of X-ray units. I expect that this experiment could be helpful for manufacturer to make both the X-ray equipment better, In terms of Ideal exposure factors, thereby reducing the patient dose. Experimental results are as follow : 1) X-ray output The ratio of X-ray output of single, three phase and inverter type of X-ray generator was 1 : 1.6 : 2 without absorber and 1 : 2 : 2.6 with 20 mm aluminium absorber. 2) Beam quality The X-ray beam quality of single phase generator was proved to be softer than three phase and inverter type of generators by 0.4 mmAL and 0.55 mmAl HVL respectively. 3) Reproducibility Linearity of X-ray output Retroducibility of X-ray output met the regulation below CV 0.05 and linearity also met the regulation below 0.1 in 4 types of diagnostic X-ray generators. 4) The comparison of incident dose Three phase X-ray generator was 20% higher than two other X-ray generators in radiation dose to make same film density.

Purpose: This study investigated how interprofessional education (IPE) related to medication for undergraduate healthcare students, including nursing students, has been designed and conducted. Furthermore, the outcomes of these IPE programs were evaluated. Methods: A scoping review was performed to understand the content and methods of IPE on medication for undergraduate healthcare students, including nursing students. A literature search was done using PubMed, Cumulative Index to Nursing and Allied Health Literature, Embase, Research Information Sharing Service, and Korean Nursing Database in English between January 2000 and December 2022. In total, 14 papers were selected and reviewed. Results: Eleven research studies were conducted on the implementation of one-time IPE on medication safety or errors. Among them, six studies focused on providing IPE to nursing students alongside medical and pharmacy students, while three studies targeted nursing and medical students, and two studies focused on nursing and pharmacy students. The most commonly employed educational method was simulation, which was utilized in 12 studies. All studies consistently reported a positive impact on attitudes toward IPE and effective communication. Additionally, five studies evaluating medication knowledge reported improvements in participants' understanding of drugs. Conclusion: The effects of IPE related to medication for undergraduate nursing students have been confirmed. It is necessary to introduce IPE in the field of pharmacology.

Cervical cancer is one of the most frequent cancers in women worldwide. Persistent infection with a human papillomavirus (HPV) is the main cause for cervical cancer. Vaccination and Pap smear screening are the best methods for prevention of the disease. The objective of this cross-sectional study was to assess the knowledge and views of upper secondary school female students in Kuala Lumpur, Malaysia, toward prevention of cervical cancer. This study was conducted from April 2009 to September 2009 in 8 schools in Kuala Lumpur area using pre-tested and validated questionnaires. Results indicated that the respondents had low knowledge of cervical cancer and its prevention although the majority of students (80.4%) had heard about the disease. The level of knowledge of cervical cancr and its prevention was significantly higher among students from the science stream (p<0.001) compared to students from the art stream. Most students (69.3%) agreed to take the vaccination if the service was available in schools. A high percentage of students (82.2%) agreed that the vaccination should be compulsory to the students. In conclusion, most students had low knowledge of cervical cancer and its prevention but they had positive attitude toward vaccination and agreed that vaccination should be compulsory. Therefore, suitable educational programmes should be developed to improve the knowledge of secondary school students on the prevention of cervical cancer.

최근 건강-의료 분야의 학과 신설 및 전공자가 급격하게 늘어남에 따라 해부학 교육의 질적 향성 및 학습자의 학습효과 증진을 도모하기 위해서는 새로운 강의방식의 도입이 필요하다. 따라서 본 연구는 해부학 과목이 전공필수로 포함되어 있는 강원대학교 2개 학과(간호학과, 스포츠과학부) 전공자들을 대상으로 해부학 강의를 위하여 강원대학교 e-러닝 센터와 함께 가상강의 컨텐츠를 개발 과정에 있어 담당교수의 역할을 분석하고, 정규교육과정에서 적용한 후, 학생들의 설문 조사와 가상강의실 운영 성과를 평가하였다. 해부학 가상강의 컨텐츠와 운영에 대하여 학생들의 만족도와 활용가능성, 난이도, 운영의 적절성에서 긍정적인 평가를 받았으며, 가상강의실 게시판 활동을 통하여 학생들이 자율적이고 능동적인 학습활동을 보여 주었다. 그러나 학생들이 개선점으로 지적한 컨텐츠의 질적 향상 및 관련 자료의 보강은 시급히 개선해야 할 부분으로 나타났다. 따라서 본 연구는 건강-의료 분야의 전공자뿐만 아니라 다양한 분야에서 요구하고 있는 강의수요에 비해 턱없이 부족한 해부학 전공 교수진의 교육 부담을 경감하고 해부학교육에 있어 새로운 지평을 열수 있는 가상강의에 대한 연구로서, 향후 해부학 강의에 있어 충분한 활용가치가 있는 효과적인 교수법이 될 것으로 사료된다.

Background: Meningiomas are the second most common primary intracranial tumors after gliomas. Epigenetic biomarkers such as DNA methylation, which is found in many tumors and is thus important in tumorigenesis can help diagnose meningiomas and predict response to adjuvant chemotherapy. We investigated aberrant O6-methyl guanine methyltransferase (MGMT) methylation in meningiomas. Materials and Methods: Sixty-one patients were classified according to the WHO grading, and MGMT promoter methylation status was examined via the methylation-Specific PCR(MSP) method. Results: MGMT promoter methylation was found in 22.2% of grade I, 35% of grade I with atypical features, 36% of grade II, and 42.9% of grade III tumors. Conclusions: There was an increase, albeit not statistically significant, in MGMT methylation with a rise in the tumor grade. Higher methylation levels were also observed in the male gender.

Purpose: This review aimed to evaluate the effectiveness of telemonitoring (TM) in the management of children and adolescents with asthma. Methods: We searched Ovid-MEDLINE, Ovid-EMBASE, CENTRAL (Cochrane Central Register of Controlled Trials), CINAHL (Cumulative Index to Nursing and Allied Health Literature), and 5 domestic databases to identify randomized controlled trials (RCTs) published through December 2017. Two reviewers independently selected relevant studies, assessed methodological quality and extracted data. We performed a meta-analysis of TM versus usual care and summarized the intervention characteristics of included studies. Results: Of the 3,095 articles identified, 8 RCTs (9 articles) were included in this review. The type of TM intervention of included studies was varying across studies (transmitted data, transmission frequency, data review, etc.). The pooled asthma control score was not significantly different between TM and usual care (standardized mean difference 0.04, 95% confidence interval (CI) -0.20~0.28). Another pooled analysis demonstrated no statistically significant difference in asthma exacerbation between TM and usual care (odds ratio 0.95, 95% CI 0.43~2.09). Overall, the pooled results from these studies revealed that TM did not lead to clinically significant improvements in health outcomes, but some studies in our analysis suggested that TM increased patient medication adherence and intervention adherence. Conclusion: The current evidence base does not demonstrate any differences between TM intervention and usual care, but TM intervention might be considered a promising strategy for the delivery of self-management support for children and adolescents with asthma. Further well-designed studies are needed to assess the effects on clinical outcomes.

Breast cancer is the most common cancer among women worldwide. The primary aim of this work was to provide an in-depth evaluation of research publications in the field of diets and breast cancer. The impact of economic outcome on national academic productivity was also investigated. Data were retrieved using Pubmed for English-language publications. The search included all research for which articles included words relating to "diets and breast cancer". Population and national income data were obtained from publicly available databases. Impact factors for journals were obtained from Journal Citation Reports$^{(R)}$ (Thomson Scientific). There were 2,396 publications from 60 countries in 384 journals with an impact factor. Among them, 1,652 (68.94%) publications were Original articles. The United States had the highest quantity (51% of total) and highest of mean impact factor (8.852) for publication. Sweden had the highest productivity of publication when adjusted for number of population (6 publications per million population). Publications from the Asian nation increased from 5.3% in 2006 to 14.6% in 2012. The Original article type was also associated with geography (p<0.001; OR=2.183; 95%CI=1.526-3.123), Asian countries produced more proportion of Original articles (82%) than those of rest of the world (67.6%). Diets and breast cancer-associated research output continues to increase annually worldwide including publications from Asian countries. Although the United States produced the most publications, European nations per capita were higher in publication output.
