Objectives: Pharmacopuncture is a new form of acupuncture treatment that injects herbal medicine into acupuncture points. This paper introduces the management status of pharmacopuncture through accreditation, and examines the effect of accreditation on pharmacopuncture management. Methods: The Accreditation System of External Herbal Dispensaries (EHDs) of traditional Korean medicine clinics announced by the Ministry of Health and Welfare in September 2018 were investigated. Results: The Accreditation System of EHDs assesses and certifies herbal medicine and pharmacopuncture preparations. Regular components for the 'pharmacopuncture' certification consist of nine standards, 30 categories, and 165 items. The nine standards include: herbal dispensary facilities, clean room management, management and organization operation, employee management, document management, continuous quality control, herbal medicine management, management of preparation, and pavement management. Conclusion: Through EHD accreditation and certification system, traditional Korean medicine clinics and EHDs can now manage pharmacopuncture medicine quality and promise safe pharmacopuncture treatment for the people.

An image fidelity assessment using the edge histogram descriptor (EHD) of MPEG-7 is presented. Neither additional data nor fragile watermarking is needed, and there is no need to access the original image as a reference. Only the EHDs of the original image and the received image are required. The peak signal-to-noise ratio (PSNR) obtained by comparing the EHD extracted from the received image and that of the original image is used to assess the noise level of the received image. Experimental results show that the PSNRs calculated from the conventional pixel-to-pixel gray level and from the proposed bin-to-bin EHD maintain a proportional relationship. This implies that the EHD can be used instead of image data for the image fidelity assessments.

실크 피브로인은 뛰어난 생체적합성 및 생분해성으로 인해 의료용 천연고분자소재로 각광받고 있으며 다양한 형태로 제조되어 이용되고 있다. 전기분사법은 고분자 용액에 고전압을 적용하여 미세입자를 제조하는 방법으로 진행과정이 간단하고 첨가제를 필요로 하지 않는다는 장점을 지닌다. 본 연구에서는 실크 피브로인 다공성 미세입자를 제조하기 위하여 폴리(에틸렌 글리콜)(PEG)을 첨가한 후 전기분사를 실시하였다. PEG를 첨가함으로써 분사원액의 전도도는 감소하였고 점도는 증가하였다. 제조된 미세입자의 크기는 PEG 첨가에 따라 감소하였는데 이는 분사용액의 전도도 및 점도보다는 피브로인과 PEG간의 상분리에 의한 효과인 것으로 보인다. 제조된 실크 피브로인 미세입자를 물에 침지한 결과 PEG가 제거되었으며 최종적으로 실크 피브로인 다공성 입자를 제조할 수 있었다. 제조된 다공성 실크 피브로인 미세입자는 약물전달체 및 조직공학용 세포전달체로 이용가능성이 높을 것으로 기대된다.
