Purpose: The purpose of this study is to find out the accuracy and usability of the three dimensional ultrasonography in measuring the size of the rotator cuff tear, especially before and after the injection of normal saline into the glenohumeral joint. Materials and Methods: 14 patients of rotator cuff tear who were diagnosed and operated from August 2007 to September 2008 were included in this study and authors compared the size of rotator cuff tear measured with three dimensional ultrasonography with the real size measured intraoperatively. In preoperative ultrasonographic evaluation, horizontal and longitudinal length of rotator cuff tear before and after injection of normal saline intraarticularly. During the arthroscopic operation the size of tear was measured by passing a Kirschner wire through a spinal needle and direct measure was performed in open surgery. Results: The average difference was 8 mm in horizontal and 1.9 mm in longitudinal length of tear without saline injection between ultrasonographic and intraoperative measure. The average difference was 4.1 mm in horizontal and 1.6 mm in longitudinal length of tear after the normal saline injection. Conclusion: In three dimensional ultrasonographic evaluation in rotator cuff tear, intraarticular normal saline injection would produce more accurate results.

This study examined the transition process of clinical laboratory technologists' national examination and job definition in Korea and compared the differences in the national examination between Korea and neighboring countries, such as Japan and Taiwan. In Korea, the number of questions made for it was 200 (1965), 200 (1977), 300 (1982), 250 (1992), 330 (2006), and 280 (2015). The practice of clinical physiology is important for real-time monitoring, given the characteristics of physiological testing. On the other hand, there are conflicts between other occupations in the working area. Clinical molecular biology needs to be established as a new major subject considering the diagnostic importance of molecular biological tests and the speed of science and technology development. Clinical laboratory operations provide policy and guidance recommendations to technologist staff. The proposed clinical laboratory technologists' national examination comprises major subjects: clinical biochemistry, clinical hematology, clinical transfusionology, clinical immunology, clinical microbiology, clinical molecular biology, clinical histology, clinical cytology, clinical physiology, and clinical laboratory operations. In addition, this study proposes the job definition of clinical laboratory technologists, revising various chemical or physiological testing to biomedical or physiological testing required for medical practice.

복잡한 음성장애를 이해하기 위해서는 음성관에 대한 여러 단계에서의 정량적인 검사가 이루어져야 한다. 이를 위하여 여러 가지 검사 법이 이용되고 있는데 예를 들면 음성의 인지적 검사(perceptual intelligibility), 음향음성학적검사(acoustic analysis), 공기역동학적 검사(aerodynamic study), 후두구조물의 운동 관찰, 그리고 근과 신경의 기능 검사(electromyographic study)등이 있다. 이중 인지적 검사는 청취자 동의 문제와 검사 법에 대하여 문제점이 제기 되기도 하며 발화 중 후두기능의 병태생리에 관한 추론적인 정보만을 제공한다는 문제점이 있다. 음향음성 검사는 이미 잘 알려진 상태로서 많은 parameter들이 측정되어온 것이 사실이나 그 유용성에 대해서도 아직 논란이 있으며 단지 성대의 진동에 의해 나타나는 현상만을 이용한 검사로서 일종의 정지성 연구에 불과한 것이 사실이다.

Nerve conduction studies (NCS) are the most objective measure of nerve function and essential for the diagnosis of sub-clinical neuropathy in diabetes mellitus and diabetic polyneuropathy (DPN). This study evaluates the characteristic of electrophysiological abnormalities in DPN. Electrodiagnostic data from 120 patients with diabetic polyneuropathies and 77 control subjects were reviewed. Motor nerve conduction velocities (MNCV), distal motor latencies (DML), compound muscle action potential (CMAP) amplitudes, No potential frequency and conduction block were analyzed. Data were normalized based on normative reference values, and the proportion of nerves with abnormal values in the lower and upper limbs were evaluated. DPN was systemic demyelinating peripheral polyneuropathy and more severe abnormal nerve conduction was found in lower limbs than in upper limbs. The abnormal degree was more severe in peroneal nerve. It was no statistically significant difference of conduction block in control and DPN group. Our findings suggest that DPN had more common and severe peroneal nerve involvement in the motor nerve conduction studies (MNCS). These findings have important implications for the electrophysiological evaluation of DPN.

This study aimed to investigate the association between asthma and emotions, such as depression, stress, and health awareness. We observed the effects of blood indices on asthma in Korean adults. Data from 5852 adults were taken from the 2017 Seventh Korea National Health and Nutrition Examination Survey and analyzed using a multivariate logistic regression model. The probability of asthma occurrence in over 65 years old was higher than in 19-44 years old (OR = 1.48), and asthma occurrence was high in subjects with low educational (OR = 1.89) and income (OR = 2.07) levels. With regard to marital status, singleness and divorce and dye were found to have increased the probability of asthma occurrence by 1.62- and 2.30-folds, respectively. The restriction of activities was another factor that increased with asthma occurrence (OR = 2.39). In terms of emotions, general health awareness was significantly 3.45 times increased the probability of asthma occurrence at their health bad awareness. Furthermore, depression (OR = 1.782) was shown to have increased asthma occurrence. The blood index of C-CRP 1.12 times increased the probability of asthma occurrence. The factors that influenced asthma occurrence were age, education, income, marital status, the restriction of activities, general health awareness, depression, and C-CRP. Emotional factors and blood indices are potential risk factors for the development of asthma in Korean adults. By understanding the increased risks of asthma occurrence with general characteristics and emotional factors and blood indices, the management and prevention of asthma should include the management of emotional factors.

Quantitative electroencephalography (QEEG) has been widely used in research and clinical fields. QEEG has been widely used to objectively document cerebral changes for the purpose of identifying the electrophysiological biomarkers across various clinical symptoms and for the stimulation of specific cortical regions associated with cognitive function. In electroencephalography (EEG), the difference in quantitative and qualitative analyses is discriminated not by its measurement methods and relevant clinical or research environments, but by its analysis methods. When performing a qualitative analysis, it is possible for a medical technologist or experienced researchers to read the EEG waveforms to exclude artifacts. However, the quantitative analysis is still based on mathematical modeling, and all EEG data are included for the analysis, leading the results to be affected by unexpected artifacts. In the hospital setting, the case that the medical technologists in charge of the EEG test perform academic research has been little reported, compared to other clinical physiological measurement-based research. This is because there are few laboratories specialized in clinical physiological research. In this respect, this study is expected to be utilized as a basic reference material for medical technologists, students, and academic researchers, all of whom would like to conduct a quantitative analysis.
