ABSTRACT
Good assessment is crucial for feedback on curriculum and to motivate students to learn. This study was conducted to perform item analysis on the Medical Education Assessment Consortium clinical knowledge mock examination (MEAC CKME) (2011–2016) and to evaluate several effects to improve item quality using both classical test theory and item response theory. The estimated difficulty index (P) and discrimination index (D) were calculated according to each course, item type, A (single best answer)/R (extended matching) type, and grading of item quality. The cut-off values used to evaluate P were: >0.8 (easy); 0.6–0.8 (moderate); and <0.6 (difficult). The cut-off value for D was 0.3. The proportion of appropriate items was defined as those with P between 0.25–0.75 and D ≥0.25. Cronbach α was used to assess the reliability and was compared with those of the Korean Medical Licensing Examination (KMLE). The results showed the recent mean difficulty and decimation index was 0.62 and 0.20 for the first MEAC CKME and 0.71 and 0.19 for the second MEAC CKME, respectively. Higher grade items evaluated by a self-checklist system had better D values than lower grade items and higher grade items gradually increased. The preview and editing process by experts revealed maintained P, decreased recall items, increased appropriate items with better D values, and higher reliability. In conclusion, the MEAC CKME (2011–2016) is deemed appropriate as an assessment to evaluate students' competence and prepare year four medical students for the KMLE. In addition, the self-checklist system for writing good items was useful in improving item quality.

With regard to required quantization medical quality,precise medical measurement is to influence profoundly. From the five aspects to explain the relationship of medical measurement and medical quality, and to discuss management of medical measurement on installing inside measurement administration, take specific task and complete measurement work effectively in various Grade hospitals.
ABSTRACT
Strengthening the management of medical measurement is introduced to ensure the safe use of medical equipment. The methods about strengthening the management of medical measurement is introduced from the three aspects in which strengthening the construct of measurement institution and rational allocation of staff, regulating the process to ensure the verification quality, multi-path detection and equipment to ensure that more controlled, at the same time, in maintaining the accuracy and security of instruments and equipment has done a number of exploration.
ABSTRACT
This paper presents the definition,characteristics and significance of medical measurement control in modern hospitals.It also clarifies how to found a good medical measurement system.
ABSTRACT
This paper aims to establish an evaluation target system on military medical measurement so as to increase effectiveness of metrological management on military medicine. According to evaluation method of modern industry measurement, principles of engineering economy and quality requirement of health service, such relative evaluation targets as normal military medical evaluation target, health service department evaluation target and economic effect evaluation target are expounded and proved. This system has a valuable reference to the evaluation of military.medical measurement
ABSTRACT
Objective: To evaluate economic benefits of military medical measurement. Methods: According to the record of the metrological verification from the measurement station in Nanjing military region from 2000 to 2004, database is set up by Excel 2003 and the economic benefits from 14 kinds of measuring standard are analyzed. Results In a 5-year-lifetime cycle, the NPV of 10 kinds of measuring standards were over 0, 4 kinds less than 0, the average pay back period was 4.43year, and total benefit cost ratio was 2.73. Conclusion Economic benefits have been gained obviously in the investment of military medical measurement.
ABSTRACT
A new measurement management thought satisfying actual demands and the requirements of the coming war is put forward in this paper. Combining the reality of military medical measurement, related support modes at peacetime and wartime as well as supervising modes are analyzed in detail. Several kinds of support modules their logical relations are mentioned.
