Objectives The high sensitivity of ultrasound and thyroglobulin determination for follow-up of differentiated thyroid cancer allows early detection of nonpalpable recurrences. Intraoperative localization of these small foci in previously dissected necks is a surgical challenge. We assessed the safety and effectiveness of ultrasound-guided tattooing (US-tattoo) with a charcoal suspension for localizing nonpalpable cervical recurrences after thyroidectomy for thyroid cancer. Subjects and Methods Between March 2009 and December 2010, we retrospectively reviewed 19 patients who underwent US-tattoo with injection of a charcoal suspension for recurrent thyroid papillary cancer on central neck compartment after thyroidectomy. All patients underwent the surgical dissection after US-tattoo. The complications and effectiveness of US-tattoo were evaluated. Results The technical success rate of US-tattoo for suspicious lesions was 100%. There was no complication with regard to US-tattoo. During surgery, all but one tattooed lesions were detected by surgeons. On final pathologic reports, all recurrence lesions but two cases were successfully removed. Conclusion Preoperative US-tattoo is a safe and effective method for successful reoperation of central neck compartment recurrences after thyroidectomy.

향후 우리 군은 작전소요 등 특별한 경우를 제외하고는 불용탄의 야외처리를 단계적으로 축소하지 않으면 안 될 것이며 이에 대한 환경감시는 더욱 강화될 것이다. 뿐만 아니라 NIMBY 현상 등 지역 이기주의에 따라 현재기술로 가장 안전하다고 입증된 소각 대체기술로서 환경과 폭발안전을 도모할 수 있는 새로운 기술이 요구되고 있다.

Objective : We report the effects of Korean medical treatment for Verruca Plana. Methods : We used herbal treatment, acupuncture, herbal acupuncture. To evaluate the results of this treatment, we observed the patient's condition and photographed. Results : After Korean medical treatment, the patient's warts remarkably disappeared and there was no recurrence. Conclusion : We suggest that Verruca Plana can be treated by Korean medical treatment effectively. We expect these study results help provide useful evidence of Korean medicine as an effective treatment for Verruca Plana.

Objective : Portulacae Herba (PH) can clear away heat, detoxicate, cool down blood heat. The present study was designed to investigate the effects of PH on ACD induced by 2,4-dinitrochlorobenzene (DNCB) in mice. Method : In this experiment, the effects of PH on changes in body weights, thicknesses and weights of ear, thicknesses of dorsum skin, degree of symptoms on the dorsum skin, histopathological changes of ear and dorsum skin, spleen weights, TNF-${\alpha}$ and IL-10 in serum were observed. And the effects on the proliferation rates of splenocytes were also investigated in vitro and in vivo. Results : 1. PH spread (PHS) group and PH spread plus administered (PHS+Adm) group didn't show any changes in weight and thickness of ear. 2. But in PHS and PHS+Adm group, thickness of dorsum skin decreased significantly. 3. And PHS and PHS+Adm group showed meaningful effectiveness on ACD symptoms like erythema, desquamation and keratinization. 4. In histopathological observation, hyperplasia and edema of spongy tissues were remarkably diminished in PHS and PHS+Adm group. 5. And PH reduced the proliferation rates of splenocytes in vivo and vitro study. Conclusions : PH effectively decreased symptoms of ACD in this study, therefore PH can be one of medicinal ingredients to treat ACD.

본 논문에서는 인체감전의 영향에 관한 국제표준으로서 전기적 안전요건을 설정하기 위해 사용하는 IEC 60479의 "인체감전의 생리학적 현상"에 대한 내용 중에서 일상생활에서 감전의 우려가 가장 큰 상용주파 교류에서의 감전보호에 관한 내용을 소개하고자 한다. 감전보호에 대해 IEC 60479와 함께 양대 표준이라 할 수 있는 IEEE 80의 감전보호를 위한 접지설계 개념과의 차이를 살펴 봄으로써 감전보호를 위한 접지설계에 참고가 되도록 하고자 한다.
