Objective: The purpose of this study is to review research paper on low level laser therapy (LLLT) and to improve the knowledge of LLLT field. Methods: For introduction, laser characteristics, including, wavelength, medium, beam size, power, and unit power were explained. In order to understand LLLT, tissue optics and light-biomatter interaction were briefly mentioned. We reciewed 21 Korean papers on laser acupuncture and LLLT on the viewpoint of laser apparatus. Results and Conclusion: We found that the description of laser apparatus employed for LLLT experiments were not fully written. Laser wavelength and power which are the most crucial parameters, were omitted in several papers. No paper had information on beam size. In order to have high efficacy, laser should be used with proper laser parameters. Conditions of irradiation area or acupoints should be considered too. Some future technology on laser acupuncture were mentioned.

CdO가 첨가된 고온 초전도체 Y1Ba2CU3O7-δ(CdO)x(x=0.00,0.09,0.22,0.34,0.42,0.49)를 고상 반응법으로 제작하여 상온에서 Cu 핵사중극 공명 실험을 하였다. 구리-산소 평면에 있는 63Cu(2)의 핵사중극 공명 진동수는 31.13∼31.39 MHz이고, 65Cu(2)의 공명 진동수는 28.82∼29.06 MHz이었다. 이러한 공명 진동수는 χ가 증가할수록 높은 진동수 방향으로 이동하였다. 63Cu(2)과 65Cu(2)의 NQR 공명 진동수의 비는 모든 시료가 1.08로 63Cu과 65Cu의 핵 사중극 모멘트의 비와 같았다. 구리-산소 사슬에 있는 63Cu(1)의 공명 진동수는 22.15~22.36 MHz에서 관측되었는데, χ에 따른 공명 진동수의 이동 경향은 63Cu(2)과 65Cu(2)의 경우와 비슷하였다. 선폭은 63Cu(2)과 65Cu(2)그리고 63Cu(1)의 경우 모두 약 200∼300 kHz고, 전반적으로 χ가 증가할 수록 감소하였다. 스핀-에코 방법으로 구한 스핀-스핀 이완 시간 T2는 χ가 증가함에 따라 약간씩 증가하였다. We have studied Cu-NQR in CdO-mixed high-Tc superconductor Y1Ba2Cu3O7-δ(CdO)x(x=0.00, 0.09, 0.22, 0.34, 0.42, 0.49) at room temperature prepared by solid state reaction method. In the Cu-O plane, 63Cu(2)-NQR frequencies were measured to be in the range of 31.13-31.39 MHz and those of 65Cu(2) were in the range of 28.82-29.06 MHz. The position of spectrum-peaks shifted to the higher frequency with increasing χ. The ratio of 63Cu(2) and 65Cu(2)-NQR frequencies have the value of 1.08 which is equal to the ratio of 63Cu(2) and 65Cu(2) nuclear quadrupole moment for all samples. The resonance frequencies of 63Cu(1) in the Cu-O chain have been observed in the range of 22.15-22.36 MHz and the tendency of resonance frequency behaviour with χ were nearly the same for both 63Cu(2) and 65Cu(2). The line-widths of 63Cu(2), 65Cu(2) and 63Cu(1) were observed to the value of 200∼300 kHz and they decreased with increasing χ. The spin-spin relaxation time T2 obtained by spin-echo method increased slightly with increasing χ.

Objective: We wanted to review the usefulness of ultrasonography (US) for the diagnosis of appendicitis and to evaluate the diagnostic accuracy of US according to patients' and researchers' characteristics. Materials and Methods: The relevant Korean articles published between 1985 and 2003 were included in this study if the patients had clinical symptoms of acute appendicitis. The histopathologic findings were the reference standard and the data were presented for 2 2 tables. Articles were excluded if patients had no sonographic signs of appendicitis according to graded-compression US. Two reviewers independently extracted the data on study characteristics. The Hasselblad method was used to obtain the combined estimates of sensitivity and specificity for the performance of US. Results: Twenty-two articles (2,643 patients) fulfilled all inclusion criteria. The estimate of calculated by combining the sensitivity and specificity was 2.0054 (95% confidence interval [CI]: 1.8553, 2.1554) by a random effects model. The overall sensitivity and specificity (95% CI) were 86.7% (85.4 to 88.0), and 90.0% (88.9 to 91.2), respectively. According to the subgroup meta-analysis by patients' characteristics, the estimate (95% CI) of dominantly younger age, male, and highly clinical suggestive group for US was 2.2388 (1.8758 to 2.6019), 2.7131 (2.2493 to 3.1770), and 2.4582 (1.7387 to 3.1777), respectively. Also, according to subgroup meta-analysis by researchers' characteristics, the value (95% CI) for US done by diagnostic radiologists and gray-scale was 2.0195 (1.7942 to 2.2447) and 2.2630 (1.8444 to 2.6815). Conclusion: This evidence suggests that US may be useful for the diagnosis of acute appendicitis, especially when patients are younger age, male, and highly clinical suggestive.
Health Care and Days of Disability Survey Koje Island, Korea
Yu, Seung-Hum The Korean Society for Preventive Medicine 1972 예방의학회지 Vol.5 No.1
거제(巨濟) 지역사회(地域社會) 개발(開發) 보건원(保健院)은 농촌 지역에서 보다 효과적으로 총괄적인 의료를 베풀기 위하여 세계 교회 협의회 의료 선교 위원회의 지원으로 1970년에 개원하였다. 시범 산업이기에, 사업의 효과를 여러 모로 평가하는 것이 필요하겠으며, 의료에 관한 연구도 그 중 하나라고 생각된다. 이 연구에서는 대조지역으로 프로젝트에서 가장 멀고, 교통이 제일 불편한 면을 택하였다. 월간 유병율은 일년 전보다 감소한 것을 볼 수 있었으며, 치료율은 차이가 없었으나, 의사의 치료를 받은 율이 증가하였다. 대조 지역과 비교하면 프로젝트 지역에서 보다 많이 의사의 치료를 받았다. 치료를 받지 않은 중요 이유로는 "별로 아프지 않아서"가 일년 전에 비해 증가하였고, "너무 비싸서"라는 이유가 감소하였다. 아직 사업의 효과를 평가하기에는 이르지만, 이 연구와 일년 전과를 비교할 때, 의료 수준이 높아진 것으로 보인다.
