Objectives The purpose of this study is to see the prevalence and the patterns of the use of complementary and alternative medicine (CAM) in children and adolescent patients with allergies. Methods We analyzed data on 547 children and adolescents (age from 0-18 years old) chosen from all regions throughout the country with allergic diseases, including atopic dermatitis, allergic rhinitis, asthma and allergic urticaria. We used multiple logistic regression modeling to predict CAM use based on predictor variables. Results The previous 12-months prevalence of CAM usage in overall was 70.7% (atopic dermatitis, 78.1%; allergic rhinitis, 52.9%; asthma, 70.3%; allergic urticaria, 86.3%). Central and southern regions displayed significantly lower rate of using CAM compare to the northern region, and CAM was less likely to be used for the allergic rhinitis patients than the atopic dermatitis patients. The most commonly used CAM type was natural products (62.2%). Top five of the most frequently used CAM modalities were softener water, vitamin, red ginseng, wood bathing and aloe oil. One of the main reasons for trying CAM was from the 'hope for a more effective outcomes in additional to the conventional medicine' (43.9%). The subjective effectiveness of CAM was found to be excellent in 74.0% of the patients, and 70.3% of the parents were willing to recommend CAM therapies to the others. Conclusions CAM is used widely to treat allergic diseases in children and adolescents in Korea. Korean medical doctors should actively discuss the use of CAM with the patients and provide information on the effectiveness and safety of CAM as guide in making choice for usage of CAM.

The geometrical structure of 2-ply multifilment yarn was assumed, in order to investigate the bending properties of 2-ply multifilament yarn. And angle, Ψ between single filament in the single strand and strand axis was derived by considering the changes of torsion of constituent filaments of the single strand. The angel, Ψ was expressed as a function of plying helix angle, $\alpha$p, filament helix radius, ${\gamma}$, and traverse rotation angle, $\Phi$2 of constituent filament in the single strand.

The theoretical torsional rigidity of 2-ply multifilament yam is derived in terms of mechanical values of its constituent filaments and yarn structural parameters as follows. Theoretical analysis shows that the specific torsional rigidity of 2-ply multifilament yarn increases with the ratio, Ψ of the filament torsional rigidity to the bending rigidity at low plying helix angle, but it decreases with the ratio at high Plying helix angle. The maximum specific torsional rigidity of 2-ply multifilament yam was observed with increase of plying helix angle at the low value of 9, but the torsional rigidity of it decreases with increase of plying helix angle at the high value of Ψ.

Bending rigidity (8f) of constituent filament in a single strand consisting the geometical structure of: 2- ply multifilament yarn was theoretically derived in terms of helix angle of single strand before plying(as), plying helix angle(oF) and the ratio of the distance to the filament from strand axis(Y) to strand radius(Rs) by strain energy method. And the change of bending rigidity of constituent filament was analyzed and discussed with change of the ratio of the distance to filament from strand axis to strand radius for the purpose of determining the plying twist processing condition.

배경 : 미세변화신증후군은 우리나라에서는 성인 신증후군 중에서 제일 흔한 원인 질환이다. 방법 : 1979년 1월부터 2002년 12월까지 신조직 검사로 확진된 일차성 미세변화신증후군 환자로 16세 이상 성인이면서 최소 6개월 이상 추적 관찰된 환자들을 대상으로 치료에 대한 반응과 재발에 관련된 인자들을 분석하였다. 결과 : 대상은 94명으로 남녀비는 1.6:1이었으며, 초진 시 연령은 평균 30.5 (16-73)세였고, 관찰 기간은 66 (6-297)개월이었다. 스테로이드 초치료를 한 81명 중 완전관해가 68명 (84%), 부분관해 7명 (8.6%), 저항성을 보인 경우는 6명 (7.4%)이었다. 4주까지 완전관해가 온 47명과 그 이후에 완전관해가 오거나 부분관해 또는 저항성을 보인 34명을 비교할 때, 후자에 남자가 더 많았고 (p=0.04), 신기능 저하군 (p=0.01)이 더 많았다. Cyclophosphamide와 스테로이드 복합요법 초치료를 한 환자는 10명으로 이들은 모두 완전관해가 왔다. 모든 초치료로 완전관해가 왔던 79명의 환자에서 관찰 기간 동안 재발 횟수는 0.37회/환자/년였다. 40세 이하군 (61명)과 40세 초과군 (18명)으로 나누었을 때 각각 재발 횟수는 0.44와 0.15로 후자에서 재발 횟수가 적었다 (p=0.02). 완전관해 후 관해 유지 기간을 보았을 때 40세 초과군 (p=0.005), 1일 단백뇨 10 g 이하군 (p=0.04)이 관해가 더 오래 유지되었다. 결론 : 신기능 저하가 있는 환자는 치료에 대한 반응이 좋지 않았고, 고연령 군이 재발이 적고 관해 유지 기간이 길었으며 단백뇨량이 적을 때 관해 유지 기간이 길었다. Background : Minimal change nephrotic syndrome (MCNS) is the most common cause of idiopathic nephrotic syndrome in Korea, not only in children but also in adults. Methods : We reviewed the medical records of patients older than 16 years who were diagnosed MCNS by percutaneous renal biopsy between 1979 and 2002 and followed more than 6 months there after. Results : Of total 94 patients enrolled, there were 58 men and 36 women (male to female 1.6 : 1), the mean age of onset was 30.5 (16-73) years, and the mean follow-up period was 66 (6-297) months. Of 81 patients who were initially given corticosteroid, complete remission (CR) was observed in 68 (84%), partial remission in 7 (8.6%), and failure to remission in 6 (7.4%). In comparison of the 47 patients who showed CR by the 4th week with the group who showed CR after 4 weeks plus who did not show CII after all, male (p=0.04) and renal insufficiency (p=0.01) were more dominant in the latter group. All of 10 patients who were initially given the combination of cyclophosphamide and corticosteroid showed CR. The mean number of relapse per patient per year was 0.37 in 79 patients who achieved CR with initial treatment, 0.44 in 61 patients younger than 40 years, and 0.15 in 18 patients older than 40 years (p=0.02). Remission was maintained longer in patients older than 40 years (p=0.005), and in those with proteinuria less than 10 grams per day (p=0.04). Conclusion : Among patients with MCNS, those who presented with initial renal insufficiency show a less favorable response to corticosteroid. Patients older than 40 years show less frequent relapse and longer duration of remission. (Korean J Nephrol 2004;23 (3):419- 428)
