Objective : The purpose of this study is to investigate the characteristics of patients with warts. Methods : We conducted statistics study on 100 patients, who had visited to Wart Clinic, from September 2008 to February 2009. Results : The results were as follows. 1. The wart was found more often from female(64%) than from male(36%). The age distributions of patients showed highest in 21-30 years, followed by 31-40 years, and 11-20 years. 2. The distributions of duration of warts showed highest in 1-5 years, followed by 6-10 years, and over 10 years. 3. The most common warts were Verruca plana(48%), Verruca vulgaris(25%), Verruca vulgaris with Palmoplantar wart(14%), Verruca plana with Verruca vulgaris(9%). 4. The Verruca vulgaris was found mostly in the hand, whereas the Verruca plana was seen mostly in the face. 5. Laser therapy was the most common previous treatment, followed by cryotherapy, immunotherapy in order. 6. The distributions of duration of treatment showed highest in 1-4 weeks, followed by 5-8 weeks, 9-12 weeks in order. 7. After treatment, 43 cases(43%) showed complete clearance, and 29 cases(29%) showed partial clearnace. Conclusion : We analyzed the characteristics of patients with warts. Further studies would be needed to develop the better treatment on warts.

Purpose: This study aimed to investigate the changes in the occurrence of rotavirus gastroenteritis (RGE) after the introduction of rotavirus vaccine and estimate rotavirus vaccine effectiveness in hospitalized children. Methods: We compared the retrospective data of 671 patients with acute gastroenteritis (AGE) admitted to the Department of Pediatrics, Hanyang University Seoul Hospital from January 1, 2014, to December 31, 2015, with retrospective data of 1,243 patients admitted to the same institution with AGE from January 1, 2004, to December 31, 2005. The vaccine effectiveness was estimated using a case-positive control test-negative study. Results: The proportion of RGE in AGE was significantly lower in 2014 to 2015 (9.0%, 48/531) than in 2004 to 2005 (22.7%, 282/1,243) (P<0.001). In particular, there was a significant decrease in the 6- to 11-, 12- to 23-, and 24- to 35-month-old groups (P<0.001), whose rotavirus vaccination rates were higher than the remaining age groups. The monthly distribution of patients with RGE in 2004 to 2005 was higher from November to May, peaked in January, followed by December and February. In 2014 to 2015, the monthly distribution of patients with RGE slightly peaked in January. In 2014 to 2015 study, the complete rotavirus vaccination rate was 66.0% (332/503) and incomplete vaccination rate was 6.2% (31/503). Presumed rotavirus vaccine effectiveness was 83.3% (95% confidence interval [CI], 60.5% to 92.9%) in the complete vaccination group and 27.4% (95% CI, -163.7% to 80.0%) in the incomplete group. Conclusions: The proportion of RGE in AGE has markedly decreased since the introduction of rotavirus vaccines, and improving vaccination coverage will further reduce the burden of RGE in Korea.

Objective : The purpose of this study was to investigate the effects of Combination therapy with Gwakhyangjeonggisangamibang and Sojangjeonggyeok on patients with verucca plana. Methods : Sixty-five patients(male 19, female 46) with verruca plana were treated with Gwakhyangjeonggisangamibang and Sojangjeonggyeok for at least 3 months. After treatment, a clearance rate was divided into 4 scales such as; complete clearance / partial clearance-good / partial clearance-poor / no change. Statistical analysis was performed by using Independent-sample t-test. Results : Mean age of patients was 30.3 and mean period of disease duration was 64.6 months. Fifty-eight patients(73.8%) showed complete clearance, nine(13.8%) partial clearance-good, and eight(12.3%) partial clearance-poor. Complete clearance group(CC group) was statistically younger than failure group and disease duration of CC group was shorter than failure group. Although treatment period of failure group was statistically longer than CC group and dosage(貼) of herbal medicine of failure group was more than CC group, failure group showed partial clearance. Conclusion : This data demonstrates that combination therapy with Gwakhyangjeonggisangamibang and Sojangjeonggyeok could be an effective and safe treatment for the verucca plana.

목 적: 뇌하수체저하증 환아들은 비만, 당불내성, 고지질혈증을 포함한 대사증후군의 양상을 보인다. 이 연구의 목적은 뇌하수체저하증과 연관된 소아 지방간질환의 임상 양상과 간조직 소견을 알아보는 것이다. 방 법: 뇌하수체저하증 환자 중에서 비알코올성 지방간질환으로 진단된 소아 11명의 임상자료를 조사하였다. 결 과: 뇌하수체저하증 진단 시 연령은 10.4${\pm}$3.2세였다. 지방간질환 진단 시 연령은 13.1${\pm}$2.7세였다. 두 개인 두종이 뇌하수체저하증의 기저질환 중 가장 흔하였다. 지방간질환 진단 당시 체질량지수 85백분위수 이상이 9명(82%), 금식 시 고혈당이 5명(45%), 고지질혈증이 9명(82%)에서 발견되었다. 신장의 표준편차 점수의 평균은 뇌하수체저하증 진단 시보다 지방간질환 진단시에 유의하게 낮았다. 간생검을 실시한 6명 중에서 1명은 간경변, 2명은 연결 섬유화가 동반된 지방간염, 2명은 경도의 간문맥 섬유화가 동반된 지방간염, 1명은 단순 지방간으로 진단되었다. 결 론: 뇌하수체저하증을 가진 소아는 저신장, 비만, 고지질혈증, 비알코올성 지방간질환이 발생할 위험이 높다. 간조직의 진행된 섬유화가 흔하기 때문에 뇌하수 체저하증 환아에서 지방간질환의 조기 진단이 중요하다. Purpose: It has been reported that children with hypopituitarism have features of metabolic syndrome, including obesity, impaired glucose tolerance, and dyslipidemia. The aim of this study was to investigate the clinical features and liver histology of pediatric non-alcoholic fatty liver disease (NAFLD) associated with hypopituitarism. Methods: We reviewed the clinical data of 11 children diagnosed with NAFLD among patients with hypopituitarism. Results: The mean age at the time of diagnosis of hypopituitarism was 10.4${\pm}$3.2 years, and the mean age at the time of diagnosis of NAFLD was 13.1${\pm}$2.7 years. A craniopharyngioma was the most common cause of pituitary dysfunction. At the time of diagnosis of NAFLD, 9 patients (82%) had a body mass index greater than the 85th percentile, 5 patients (45%) had elevated fasting blood glucose levels, and 9 patients (82%) had hypertriglyceridemia. The mean height SD score was significantly lower at the time of diagnosis of NAFLD than at the time of diagnosis of hypopituitarism. Of the six patients who were biopsied, one had cirrhosis, two had non-alcoholic steatohepatitis (NASH) with bridging fibrosis, two had NASH with mild portal fibrosis, and one had simple steatosis. Conclusion: Children with hypopituitarism are at risk of short stature, obesity, dyslipidemia, and NAFLD. The early diagnosis of NAFLD is important in children with hypopituitarism because advanced fibrosis is common.
Wake-Up Radio 네트워크에서 RIS 자가 변조 방법을 활용한 AP의 선택적 단말 제어 프로토콜
윤정민(Jung-Min Yoon),김경민(Kyoung Min Kim),이태진(Tae-Jin Lee) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.6
기존 Wake-Up 기반의 네트워크에서는 Wake-Up 신호를 수신한 특정 단말들이 AP(Access Point)로 채널 경쟁을 통해 데이터를 전송하기 때문에 AP가 특정 단말의 데이터를 신속하게 수집하기 어려웠다. 본 논문에서는 WLAN(Wireless Local Area Network) 환경에서 AP가 RIS(Reconfigurable Intelligent Surface)의 다중 빔 전송 방법을 활용해 Wake-Up 신호와 단말의 제어 정보를 특정 단말로 전송하는 MAC(Medium Access Control) 프로토콜을 제안하였다. 제안 방법을 통해 AP가 선택적으로 특정 무선 센서 단말을 Active 모드로 동작 시켜 필요한 데이터를 수집함으로써 단말들의 불필요한 경쟁과 에너지 낭비를 최소화하였다. 시뮬레이션을 통해 제안 방식이 기존 방식에 비해 수신 지연 시간 성능이 향상되었음을 확인하였다.
