Purpose: To Compare the improvement of erectile dysfunction (ED) and lower urinary tract symptoms (LUTS) as well as the efficacy of mirodenalfil 50mg once daily and 100mg on-demand in patients with benign prostatic hyperplasia (BPH) and erectile dysfunction (ED). Materials and Methods: Prospective study was done with 220 patients who had BPH and ED from June 2013 to October 2014. Out of 220 individuals, 260 met inclusion criteria and 204 finished the research. Patients were divided into two groups. Group 1 had mirodenafil 50mg once daily and Group 2 had mirodenafil 100mg on-demand. The five-item version of the International Index of Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS), Qmax, and residual urine volume(PVR) were assessed immediately before initiation of treatment (V1) and after four (V2) and twelve weeks of treatment (V3). Results: No difference of IIEF-5, IPSS, Qmax, and PVR between two groups in V1. At V3, both groups had improvements of IPSS and group 1 had better improvements (-5.1±4.4 vs. -3.1±3.9 p<0.001). And Group 1 had larger improvements than Group 2 in Qmax significantly. No difference in PVR in both groups comparing V1 vs. V2 and V1 vs V3. Group 1 had better improved IIEF-5 than Group 2 (V1 vs. V3 : 4.8±5.8 vs. 4.4±5.1; p=0.032). There was no drop out patients due to cardiovascular problems. Conclusions: Once daily mirodenafil 50mg was more efficacious in treating both ED and LUTS than on-demand dosing mirodenafil 100mg without any complication of cardiovascular problems.

Purpose: Pathogenically, both erectile dysfunction (ED) and benign prostatic hyperplasia (BPH) are closely related to vascular problems, and vascular problems are closely associated with obesity. This study evaluated the relationships between obesity, BPH, and ED. Materials and Methods: The medical history of male patients, aged ≥40 years, evaluated at urology outpatient clinics of 11 university hospitals in Korea with chief complaints of lower urinary tract symptoms (LUTS)/BPH and ED were retrospectively evaluated. The correlations of medical history, body mass index (BMI), international prostate symptom score (IPSS), prostate volume, International Index of Erectile Function -5 (IIEF-5), and serum testosterone level were assessed. Results: Body mass index showed significant correlations with IPSS (r=0.087, p=0.003), prostate volume (r=0.384, p<0.001), IIEF (r=-0.072, p=0.015), and serum testosterone concentration (r=-0.303, p<0.001). Conclusions: Body mass index correlates with testosterone concentration, prostate volume, and markers of LUTS and ED in men with the latter conditions.

전국 관광명소 이미지 데이터 기반의 EfficientNet 모델을 활용한 이미지 분류 분석
박기태 ( Ki-tae Park ),조중훈 ( Joong-hun Cho ),최상현 ( Sang-hyun Choi ) 사단법인 한국빅데이터서비스학회 2023 빅데이터서비스학회 논문집 Vol.1 No.2
In the post-pandemic recovery period, service-based tourism platforms are being actively developed for efficient data management in the tourism industry and customized tourism recommendations for travelers. These tourism platforms require various new attempts and high-quality services to attract travelers to tourist destinations. Therefore, tourism platforms are using basic tourist information data for personalized tourist suggestions, but there are limitations in fully reflecting the specific needs and preferences of users. To study technologies that can help personalize and customize services through efficient classification and management of tourist image data and efficient data management, we conducted a study to classify tourist images into categories using the EfficientNet model using OpenAPI data from the Korea Tourism Organization. The study used Version B7 of the EfficientNet model to classify tourist images into 36 subcategories, and the classification accuracy of the model was 85.15%. However, the accuracy performance of the model decreased as the data was trained, and there was a need to improve the accuracy by securing additional data for each class.

본 연구는 예비남자유아교사들이 교과목 학습수행에서 강점을 보이는 분야와 취약함을 보이는 분야를 파악하여 유치원 현장에서의 남자교사의 역량 기반과 활동의 참고자료로 활용하고자 실시되었다. 연구대상은 예비남자유아교사 10명이었으며, 연구결과는 다음과 같다. 첫째, 남자예비유아교사들은 유아교육학과에서 유아교사가 되기 위한 지식과 기술, 태도를 배울 것이라고 예상하였으나, 실제로는 예상보다 세분화, 전문화된 내용을 배웠다고 응답하였다. 전공교과에서는 신체활용이 많은 교과목의 학습수행이 수월하였고, 예능교과에서 수행에서는 어려움을 경험했다고 하였다. 둘째, 전공필수 교과목은 아동간호학, 유아사회교육, 유아동작교육 순으로 학습결과가 좋은 것으로 나타났으며 전공 선택 교과목은 보육실습, 아동 및 청소년 음악치료, 유아체육 및 레크레이션 순으로 학습결과가 좋은 것으로 나타났다. 교직과목 학습수행에서는 이론중심이기 때문에 남녀의 차이가 크게 나지 않고 비교적 수월하였던 것으로 나타났다. 교직과목에서는 교육행정 및 교육경영, 교육방법 및 교육공학, 교육실습 순으로 학습결과가 좋은 것으로 나타났다. This study examined the learning performance of the subjects during school to find out the areas in which male pre-service in early childhood teachers show strength and vulnerability. For this purpose, 10 prospective male infant teachers who are attending or are expected to graduate from the department of early childhood education atUniversity in Seongnam City. The results were as follows. First, the survey on pre-school expectations of male pre-service in early childhood teacher and changes in their perception after classes showed that the department of infant education expected to learn knowledge, skills and attitudes to become infant teachers, but responded that it actually learned more detailed and specialized contents than expected. In the performance of major subjects, it was found that subjects using the body were easy to perform, and that they had difficulty in sharing roles in entertainment subjects and detailed roles, especially in group activities. Second, the subjects that said the results of major required subjects were good followed by nursing, social education for infants and children, and children s and youth music therapy, and infant sports and recreation. In the course of teaching, it was found that the difference between men and women was relatively easy because it was based on theory. The subjects of teaching were education administration and education management, education methods and education engineering, and education practice.
