Background: We aimed to investigate the analgesic efficacy of an erector spinae plane block (ESPB) in immediate breast reconstruction (IBR) with a tissue expander. Methods: Adult women undergoing IBR with a tissue expander after mastectomy were randomly assigned to either intravenous patient-controlled analgesia (IV-PCA) alone (group P) or IV-PCA plus ESPB (group E). The primary outcome was the total amount of opioid consumption during 24 hours postoperatively between the two groups. Secondary outcomes were patient satisfaction, pain score at rest and on shoulder movement using numerical rating scale, incidences of postoperative nausea and vomiting (PONV), and a short form of the brief pain inventory (BPI-SF) at 3 and 6 months after surgery between the groups. Results: Fifty eight patients completed the study. At 24 hours postoperatively, total opioid consumption was significantly less in group E than in group P (285.0 ± 92.0, 95% confidence interval [CI]: 250.1 to 320.0 vs. 223.2 ± 83.4, 95% CI: 191.5 to 254.9, P = 0.005). Intraoperative and cumulative PCA fentanyl consumption at 3, 6, 9, and 24 hours were also less in group E than in group P (P = 0.004, P = 0.048, P = 0.020, P = 0.036, and P < 0.001, respectively). Patient satisfaction was higher in group E (6.9 ± 1.8 vs. 7.8 ± 1.4, P = 0.042). The incidences of PONV was similar. Conclusions: The ESPB decreased postoperative opioid consumption and increased patient satisfaction without significant complications after IBR with a tissue expander after mastectomy.

The performance of a passenger vehicle has been greatly improved recently owing to the intensive use of electronic controllers. Many components of a vehicle, including the engine, are controlled by electronic systems installed in the vehicle. Therefore, the electrical power required for such electronics has increased significantly. However, the electrical power generated by the vehicle’s alternator, operated by the engine, is limited, and when the vehicle is started, a large instantaneous current is required. The voltage of the vehicle electrical system fluctuates to a very low level, then, it is gradually recovered. This case is very severe and can even cause damage to electronic systems. In this study, a voltage-stabilizing module comprising electric double layer supercapacitors, which could alleviate the voltage variation, was developed and tested.

Recently, there are many opinions to develop rural tourism. Especially, how to make rural objects for rural tourism resources. The contents of tourism products is very important in tourism market. The purpose of this paper are to make clear the concept of tourism products and to present the strategies to make rural tourism resources for rural tourism products. There are four basic strategies, three strategies in the respect to the organization and four strategies at the dimension of products. Before making tourism products, we must find something for rural tourists to make something to do at rural destinations. There are 7 ways to make something to do. Then we can choose and arrange them for rural tourist products.<br/> <br/>

영상등록은 영상모자잌기술 중 중요한 기술로 인식되고 있으며, 파노라마 영상생성이나 비디오 모니터링, 영상복원 등과 같은 다양한 분야에서 사용될 수 있다. 영상등록에서 중요한 처리과정은 많은 시간이 소요되는 특징점 검출과 추적이다, 본 연구에서는 연속된 영상자료에서 특징점을 검출하고 추적하기 위해서 KLT 특징점 추적자를 제안하였으며, 무인헬기에서 촬영된 연속영상프레임의 영상등록에 적용하여 효용성을 입증하였다. 그 결과 KLT 추적자에 의한 반복처리는 연속영상의 첫 번째 프레임에서 추출된 특징점을 이용하여 전체 프레임에 걸쳐 성공적으로 추적할 수 있었다. 또한, 회전, 축척, 이동량이 다른 각각의 프레임들간의 특징점추적은 KLT영상피라미드와 처리조건의 선택에 의해 정확도를 향상시킬 수 있었다. Image registration is one of the critical techniques of image mosaic which has many applications such as generating panoramas, video monitoring, image rendering and reconstruction, etc. The fundamental tasks of image registration are point features extraction and tracking which take much computation time. KLT(Kanade-Lucas-Tomasi) feature tracker has proposed for extracting and tracking features through image sequences. The aim of this study is to demonstrate the usage of effective and robust KLT feature detector and tracker for an image registration using the sequence image frames captured by UAV video camera. In result, by using iterative implementation of the KLT tracker, the features extracted from the first frame of image sequences could be successfully tracked through all frames. The process of feature tracking in the various frames with rotation, translation and small scaling could be improved by a careful choice of the process condition and KLT pyramid implementation.

Purpose: The purpose of this study was to develop and test the validity and reliability of the Korean version of the Perinatal Infant Care Social Support (K-PICSS) for postpartum mothers. Methods: This study used a cross-sectional design. The K-PICSS was developed through forward-backward translation. Online survey data were collected from 284 Korean mothers with infants 1-2 months of age. The 19-item K-PICSS consists of functional and structural domains. The functional domain of social support measures infant care practices of postpartum mothers. Exploratory factor analysis (EFA) and known-group comparison were used to verify the construct validity of the K-PICSS. Social support and postpartum depression were also measured to test criterion validity. Psychometric testing was not applicable to the structural social support domain. Results: The average age of mothers was 32.76±3.34 years, and they had been married for 38.45±29.48 months. Construct validity was supported by the results of EFA, which confirmed a three-factor structure of the scale (informational support, supporting presence, and practical support). Significant correlations of the K-PICSS with social support (r=.71, p<.001) and depression (r=-.40, p<.001) were found. The K-PICSS showed reliable internal consistency, with Cronbach’s α values of .90 overall and .82-.83 in the three subscales. The vast majority of respondents reported that their husband or their parents were their main sources of support for infant care. Conclusion: This study demonstrates that the K-PICSS has satisfactory construct validity and reliability to measure infant care social support in Korea.

웹 응용 관련 기술이 널리 이용되면서 적은 비용, 짧은 개발 기간, 고품질 등 새로운 요구사항이 등장하고 있다. 웹 응용 개발 현장에서는 이러한 요구사항을 만족시키기 위하여 개발 초기부터 UI 프로토타입(UI Prototype)을 적극적으로 이용하는 방법을 택하고 있다. UI 프로토타입에에는 클라이언트 측의 항해가 구현되어 있기 때문에, 항해 설계 활동(Navigation Design Activity)이 불필요하다고 생각할 수 있다. 그렇지만 UI 프로토타입의 복잡성과 비정형성 때문에 큰 규모의 웹 응용 개발 과정에서 요구사항을 만족시키지 못할 가능성도 있다. 이 논문에서는 항해 모델을 이용하여 웹 응용 전체를 쉽게 파악할 수 있고, 사용자 관점 및 서버 관점에서 항해의 문제점을 파악할 수 있다는 점을 근거로 UI 프로토타입에 기반한 항해 설계의 필요성을 제시한다. 그리고 웹 응용 개발 프로세스에서 항해와 관련한 활동들의 세부 단계를 밝히고, UML SPEM 프로파일(Profile)을 이용하여 세부 단계를 표현한다.

놀이중심 교육과정에 기초한 유아들의 실내 놀이 공간 활용 탐색

박서연(Seoyeon Park),이숙희(Sukhee Lee),권미량(Meeryang Kweon) 학습자중심교과교육학회 2023 학습자중심교과교육연구 Vol.23 No.15

목적 본 연구는 놀이중심 교육과정에 기초하여 유아들이 놀이하는데 실내 놀이 공간을 어떻게 변경 및 활용하는지를 현장의 실제적 장면을 통해 탐색하고자 하였다. 방법 이를 위해 S어린이집의 유아반 교사 3인과 만 3·4·5세 유아 45명을 연구참여자로 선정, 2021년 10월 18일부터 11월 5일까지 총 18회의 참여관찰과 교사당 6~8회의 면담, 유아 면담 그리고 녹화와 연구자 일지 등의 자료를 귀납적으로 분석하였다. 결과 유아들의 실내 놀이 공간 활용은 첫째, ‘공간을 넘나들며 놀이하기’로, 흥미 영역과 교실을 넘어 놀이 공간을 확장하고, 일상공간과 놀이 공간을 넘나들며 놀이하였다. 둘째, ‘새로운 놀이 공간 창조하기’로, 원하는 놀잇감을 재배치, 새로운 놀이 구조물을 구축, 교실 전체 공간을 변형하며 놀이하였다. 셋째, ‘놀이 공간 조율하기’로, 혼자만의 사적 공간을 인정하였고, 필요한 욕구에 맞추어 놀이 공간을 협의하며 놀이하였다. 이를 통해 유아는 자신의 놀이를 주도적으로 진행하고, 다른 친구와 공간을 조율하며 놀이하는 힘이 있음을 확인할 수 있었다. 결론 이는 개정 누리과정에서 지향하는 주도적인 놀이와 이러한 놀이를 통한 배움의 가치를 실현하기 위한 하나의 방법으로 놀이공간 활용의 자율성이 얼마나 중요한 요소인지를 시사한다. Objectives This study aimed to explore how young children change and utilize indoor play spaces for play through actual scenes in the field, based on the play-centered curriculum. Methods For this, three early childhood teachers and 45 children aged 3, 4, and 5 from S Daycare Center located in Busan were selected as research participants, and were analyzed inductively using a total of 18 participant observations and 6-8 interviews per teacher, infant interviews, recordings, and researcher's journals, from October 18 to November 5, 2021. Results As a result of the study, the use of indoor play spaces by young children was classified into ‘playing across spaces’, ‘creating new play spaces’, and ‘adjusting play spaces’. Conclusions Through this, it was confirmed that infants have the power to play by leading their own play and coordinating space with other friends. This suggests how important the leading play aimed at in the revised Nuri Curriculum and the autonomy of play space utilization as a way to realize the value of learning through play is.
