Medical act divides unlicensed medical practice into medical practice by non-medical practitioners and unlicensed practice by medical practitioners. In the past, it was a common approach to strictly distinguish between western and Korean medicine, but the Supreme Court's Decision of December 22, 2016, Do. 21314, provided a new direction regarding the criteria for determining whether a Korean medicine practitioner is acting outside license. This paper analyzes the new criteria in detail, examines the significance of the new criteria, and explores its impact on the dualistic medical system. The difference between the new criteria and the previous criteria in the precedents is that the judgment is not based on the connection between Korean medicine principles and Western medicine principles. It is an advanced standard that actively accepts the overlap and variability of medical practice, moving away from dichotomous thinking that exclusively distinguishes between Korean medicine and Western medicine.

Objectives: This study investigated public opinion on the use of modern diagnostic medical devices by Korean Medicine doctors. Methods: A questionnaire looking into perceptions on the use of modern medical devices was developed. It was distributed by a third party and data was collected. Results were analyzed through frequency analysis, chi-square analysis (χ²-test), frequency and cross analysis using R program. The measurement variable in the study was the respondent's perspectives and expectations on the use of modern diagnostic medical devices by Korean Medicine doctors. The maximum significance level was 0.05. Results: There were a total of 3,000 responses and 80.8% of the respondents replied that there is a need for government-level discussion on endowing rights to Korean Medicine doctors as supervisors for safety management of radiation generating devices. Also, 83.3% of the respondents agreed the use of ultrasound imaging equipment in Korean Medicine clinics should be legalized. Conclusions: According to this study, respondents strongly support the use of modern diagnostic medical devices by Korean Medicine doctors. This is the first study to investigate public opinion in this area and it provides a significant insight into the public needs and desires for a wider scope of practice for Korean Medicine in the healthcare system.

A laser ultrasonic inspection system is a non-contact inspection device which generates and measures ultrasounds by using laser beams. A laser ultrasonic inspection system provides a high measurement resolution because the ultrasonic signal generated by a pulse laser beam has a wide-band spectrum and the ultrasonic signal is measured from a small focused spot of a measuring laser beam. In this paper, we have investigated the detection techniques of a surface-breaking crack by using the laser ultrasonic surface waves. A crack acts as a low pass filter whose cut-off frequency is lowered in proportion to the depth of a crack. And, the center frequency value of a spectrum is decreased in proportion to the depth of a crack. In this paper, we extracted the crack information by using the frequency attenuation from the normalized transfer function spectrum of a surface-breaking crack. Also, we effectively measured the crack depth by using the decreasing value of the center frequency from a crack passed ultrasonic signal. The proposed measuring techniques of crack depths provided more precise information than the amplitude measuring technique.
