In recent years, medical practice has seen a drastic change due to the rapid, exponential expansion of scientific and medical technologies. Specially, the role of medical technologists (also known as medical laboratory scientists and/or clinical laboratory scientists) are increasing in the development of science of medical technology. As such, their responsibility has also been increasing. Therefore, given their highly specialized knowledge and skills, they are not regarded solely as doctor's assistants. Their independence and deeper specialization have been increasing, as they perform medial practices under the guidance of doctors or dentists pursuant to the "Act on Medical Service Technologists." From a legal point of view, medical guidance and scope of work were examined. As a conclusion, the definition of doctor's superintendency on the "Act on Medical Service Technologists" is required, and the qualification for the Korean license examination and their roles should be stated clearly. Moreover, communications among health professions regarding the roles of medical technologists are necessary to further facilitate clarification of their role. There is a need for independent legislation to expand the field of medical technologists and to strengthen their professionalism.
This study analyzed the curriculum and clinical practicum of the department of clinical laboratory science in Korea. The 2017 educational curricula of all 3-year and 4-year universities were analyzed. Clinical practice was conducted by a questionnaire. As a result of curriculum analysis, the 3-year curriculum was able to grasp the curriculum that focused on the national examinations of medical technologists, and the 4-year curriculum was open to a variety of subjects reflecting the changes in the future, but only at a few universities. In addition, the autonomous enrollment application made it possible to take a national examination without enrolling in courses that students find difficult in major courses. In the case of clinical practice, it was difficult to standardize in various practical institutes, practice periods, and practice credits. Therefore, it will be necessary to standardize the composition of the credits according to the duration of clinical practice and the duration of education. Moreover, is necessary to revise the curriculum in consideration of medical technologist job analysis and clinical field, and it will be necessary to standardize the curriculum and clinical practice model through the Medical Technologist Evaluation Center.
In vivo labeling of bone with fluorochromes is a widely used method for assessment of bone formation and remodeling processes. In particular, calcein is used as a marker for identification of bone growth, which is indicated by a green color. Calcein green is a calcium chelator that adheres to regions of mineralizing bone thereby allowing localization of new bone. Bone formation and remodeling in vivo can be assessed by calcium-binding calcein labeling. In this study, changes in the femoral bone of a normal mouse model at both 4 and 8 weeks were evaluated using calcein labeling. Intense deposition of calcium in the bone was observed after application for 8 weeks. A mouse model is suitable for application in in vivo experiments using genetically modified mice, such as knock-out mice, however data regarding femoral cross sectional bone in young mice are limited. The current study confirmed calcein as a useful marker for identification of bone growth, which was indicated by a green color on photomicrographs. This methodological process may provide basic information for interpreting bone formation and regeneration to pharmacologic or genetic manipulation in mice.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
