Purpose: This study was designed to determine the test-retest, inter-rater, and intra-rater reliability of the Pediatric Balance Scale (PBS) when applied to children with cerebral palsy (CP). Methods: Subjects were out-patient children with cerebral palsy at four CP clinics in Gyeonggyi-do and Chungcheong nam-do. For test-retest and inter-rater reliability studies, the PBS was used twice on 7 separate days by twenty-four children with CP. To assess intra-rater reliability, 10 CP subjects were selected by random sampling. Four pediatric-trained physical therapists with 2-13 years of clinical experience scored the children’s performance blindly, while replaying videotaped data. Results: There was no significant difference in total scores (ICC 3,1=0.89, 0.93, 0.90, and 0.91) measured by each of the four therapists on two occasions. The Inter-rater reliability assessed the 1st and 2nd time was high (1stICC 3,1=0.91, 2nd ICC 3,1=0.93). The intra-rater reliability measured by each of the four therapists using the 2nd scores was also high (ICC 3,1=0.98, 0.99, 0.97, and 0.98). Conclusion: The PBS is reliable. We believe that it can be used in characterizing children with CP.

A more interactive teaching-learning system is increasingly necessary in the consumer-oriented environment of distance education. This article would like to suggest a more spontaneous system which is learners at various levels. The suggested system keynotes its efficiency with the introduction of a "mobile agent" concept through which learners are able to network and complete their assignments despite their dispersed environments. This article also suggests some managerial techniques for the systematic management of agent-based learners possessing diverse characteristics. Through this study, we expect more highly effect by offer data adapted to learning goal to learner's ability, get out of uniform web-based teaching-learning.

Background: Although oral isotretinoin is an effective established therapy for acne, Korean data related with this therapy is very limited. Moreover, there is no published data available on the efficacy of this drug that uses a grading system suitable for Korean acne patients. Objective: The purpose of this study is to evaluate the efficacy of oral isotretinoin (Roaccutane(R)) by using the Korean Acne Grading System (KAGS) and the general satisfaction of patients in treating acne. Methods: In this multicenter and prospective clinical study, 499 patients with acne, who visited at 5 dermatologic clinics during 11 months, were enrolled. The drug dosage was 0.2∼1.0 mg/kg/day over 4 months. The efficacy assessment was performed at baseline and monthly after, with an acne grading based on the KAGS and the patient satisfaction questionnaire. Results: Out of the 499 patients, 435 and 371 have completed the 3-month and 4-month treatments, respectively. After the 4-month treatment, the mean acne grades significantly decreased from 2.71 to 0.68, thus showing a 75.9% reduction in pretreatment scores. The mean patient satisfaction scores improved at the end of 4-month treatment, showing a 4.42 out of 5. Conclusion: In this paper, we describe the efficacy of oral isotretinoin by using the KAGS, which has not been previously reported in the Korean literature. Our results show that oral isotretinoin is an effective and satisfactory treatment modality for acnes of all grades in Korean patients, regardless of the dosage.

Intravascular papillary endothelial hyperplasia (IPEH), a benign, reactive vascular lesion, is characterized by the development of endothelial-lined papillary projections in a vascular lumen. Although there has been some controversy about the nature of IPEH, most investigators favor the idea that IPEH usually results from a peculiar organization of a thrombus. The lesions are frequently located in the subcutis of the fingers, hands, forearms, head and neck as a solitary, often tender, bluish or reddish nodule. We report a rare case of IPEH arising on the left sole, an unusual site. IPEH should be among the differential diagnosis of tender lesions on the soles. (Korean J Dermatol 2008;46(1):113∼116)
