Labia Majora Share

Lee, Hanjing,Yap, Yan Lin,Low, Jeffrey Jen Hui,Lim, Jane Korean Society of Plastic and Reconstructive Surge 2017 Archives of Plastic Surgery Vol.44 No.1

Defects involving specialised areas with characteristic anatomical features, such as the nipple, upper eyelid, and lip, benefit greatly from the use of sharing procedures. The vulva, a complex 3-dimensional structure, can also be reconstructed through a sharing procedure drawing upon the contralateral vulva. In this report, we present the interesting case of a patient with chronic, massive, localised lymphedema of her left labia majora that was resected in 2011. Five years later, she presented with squamous cell carcinoma over the left vulva region, which is rarely associated with chronic lymphedema. To the best of our knowledge, our management of the radical vulvectomy defect with a labia majora sharing procedure is novel and has not been previously described. The labia major flap presented in this report is a shared flap; that is, a transposition flap based on the dorsal clitoral artery, which has consistent vascular anatomy, making this flap durable and reliable. This procedure epitomises the principle of replacing like with like, does not interfere with leg movement or patient positioning, has minimal donor site morbidity, and preserves other locoregional flap options for future reconstruction. One limitation is the need for a lax contralateral vulva. This labia majora sharing procedure is a viable option in carefully selected patients.

Background: The combination of polycaprolactone and hyaluronic acid creates an idealenvironment for wound healing. Hyaluronic acid maintains a moist wound environment andaccelerates the in-growth of granulation tissue. Polycaprolactone has excellent mechanicalstrength, limits inflammation and is biocompatible. This study evaluates the safety and efficacyof bio-conjugated polycaprolactone membranes (BPM) as a wound dressing. Methods: 16 New Zealand white rabbits were sedated and local anaesthesia was administered. Two 3.0×3.0 cm full-thickness wounds were created on the dorsum of each rabbit, betweenthe lowest rib and the pelvic bone. The wounds were dressed with either BPM (n=12) orMepitel (n=12) (control), a polyamide-silicon wound dressing. These were evaluatedmacroscopically on the 7th, 14th, 21st, and 28th postoperative days for granulation, reepithelialization,infection, and wound size, and histologically for epidermal and dermalregeneration. Results: Both groups showed a comparable extent of granulation and re-epithelialization. Nosigns of infection were observed. There was no significant difference (P>0.05) in wound sizebetween the two groups. BPM (n=6): 8.33 cm2, 4.90 cm2, 3.12 cm2, 1.84 cm2; Mepitel (n=6):10.29 cm2, 5.53 cm2, 3.63 cm2, 2.02 cm2; at the 7th, 14th, 21st, and 28th postoperative days. The extents of epidermal and dermal regeneration were comparable between the two groups. Conclusions: BPM is comparable to Mepitel as a safe and efficacious wound dressing.

Efficient Viewer-Centric Depth Adjustment Based on Virtual Fronto-Parallel Planar Projection in Stereo 3D Images

Hanje Park,Hoonjae Lee,Sanghoon Sull IEEE 2014 IEEE transactions on multimedia Vol.16 No.2

<P>This paper presents an efficient method for adjusting the 3D depth of an object including as much as a whole scene in stereo 3D images by utilizing a virtual fronto-parallel planar projection in the 3D space perceived by a viewer. The proposed method just needs to establish object correspondence instead of the accurate estimation of the disparity field or point correspondence. We simulate the depth adjustment of a 3D point perceived by a viewer through a corresponding pair of points on the stereo 3D images by moving the virtual fronto-parallel plane on which the left and right points are projected. We show that the resulting transformation of image coordinates of the points can be simply expressed by three values of a scale factor and two translations that depend on one parameter for the depth adjustment. The experimental results demonstrate the feasibility of the proposed approach that yields less visual fatigue and smaller 3D shape distortion than the conventional parallax adjustment method. The overall procedure can be efficiently applied to each frame of a stereo video without causing any artifact.</P>

적응적 파라미터 추정을 통한 향상된 블록 기반 배경 모델링

김한준(Hanj-Jun Kim),이영현(Young-Hyun Lee),송태엽(Tae-Yup Song),구본화(Bon-Hwa Ku),고한석(Han-Seok Ko) 한국컴퓨터정보학회 2011 韓國컴퓨터情報學會論文誌 Vol.16 No.4

본 논문에서는 모델 히스토그램 개수를 적응적으로 조절하는 블록기반의 배경 모델링 방법을 제안한다. 기존의 블록 기반의 배경 모델링 방법은 각 블록에 대한 모델 히스토그램의 개수를 고정한다. 따라서 조명변화와 움직이는 객체에 대해 오검출이 발생하는 문제가 있고 움직임이 없는 객체에 대해서는 검출이 되지 않는 문제가 있다. 또한 입력영상의 종류마다 달라질 수 있는 최적의 모델 히스토그램의 개수를 수동적으로 찾아야 하는 문제가 있다. 본 논문에서는 실험을 통해 엘리베이터 내에서 조명변화가 있고 객체가 움직이는 상황과 조명변화가 없고 객체가 정지해 있는 상황에 대해 기존의 방법과 성능을 비교하여 제안한 알고리즘의 효용성을 입증한다. In this paper, an improved block-based background modeling technique using adaptive parameter estimation that judiciously adjusts the number of model histograms at each frame sequence is proposed. The conventional block-based background modeling method has a fixed number of background model histograms, resulting to false negatives when the image sequence has either rapid illumination changes or swiftly moving objects, and to false positives with motionless objects. In addition, the number of optimal model histogram that changes each type of input image must have found manually. We demonstrate the proposed method is promising through representative performance evaluations including the background modeling in an elevator environment that may have situations with rapid illumination changes, moving objects, and motionless objects.

The purpose of this study was to analyze the paper-pencil test items for evaluating cognitive domain in 8th grade Physical Education (PE). Paper-pencil tests that commonly used for final test in PE were used as data source. Data were collected from 14 middle schools of 11 school districts in Seoul. Total of 530 items were analyzed. Hwang (2002) and Bloom’s (1956) taxonomy were used as a framework for analysis. More specifically, we analyzed and categorized test items by types of question, topics, and levels of abstraction of questions. Results of this study showed that most of the items (96.6%) were multiple-choice types of questions. More than a third of test items (34.7%) were developed from individual and team sport areas. Also, 86.4% of items were categorized as lower level of test questions asking recall of information or comprehension of the facts. Suggestions for writing test items to assess achievement of instructional objectives and to measure an appropriate level of student knowledge were discussed.

이 연구의 목적은 학생운동선수와 일반학생의 일상생활경험을 조사하는 것이다. 한국대학교(가명) 체육학과학생 78명(학생운동선수 42명, 일반학생 36명)이 연구에 참여하였다. 경험표집 질문지를 이용하여 자료를 수집하였으며, 빈도분석, 교차분석, 단일표본 t-test를 실시하였다. 연구결과 첫째, 학생운동선수와 일반학생의 일상생활에서 경험하는 주요 활동에는 차이가 있는 것으로 나타났다. 구체적으로 학생운동선수는 여가활동, 생활유지, 운동, 학업활동 순으로 나타났으며, 일반학생은 생활유지활동, 여가활동, 학업활동, 운동 순으로 나타났다. 둘째, 학생운동선수와 일반학생의 일상생활 활동 중 활동 공간에는 차이가 있는 것으로 나타났다. 구체적으로 학생운동선수는 생활유지 공간, 학교, 공공장소, 운동관련 공간 순으로 나타났으며, 일반학생은 학교, 생활유지 공간, 공공장소, 운동관련 공간 순으로 나타났다. 셋째, 학생운동선수와 일반학생의 일상생활 중에 경험하는 내적 심리상태는 주요 활동에 따라 차이가 있는 것으로 나타났으며, 활동 공간에 따라서도 차이가 있었다. The purpose of this study was to examine college student athletes’ and non-athletes' daily time use patterns. Research question was how student athletes’ time is distributed across different activity contexts? Seventy eight undergraduate students at a university located in large urban areas participated in this study. The sample consisted of 42 student athletes and 36 non-athlete students majoring in Physical Educautin. Time use patterns were measured using the Experience Sampling Method (ESM). Participants carried a small booklet of self-report forms and completed self-report forms when signaled over the course of one week. The ESM self-reported form contained open-ended questions, such as “What were you doing just before you were signaled?” Responses to this question were categorized into five broad categories of activities: schoolwork (i.e., classwork, homework), discretionary activities (i.e., socializing, leisure), maintenance activities (i.e., eating, resting), sport activities (drill or practice related to sport), and other activities. Results of this study showed that student athletes spent 43.1% in discretionary activities, 32% in maintenance activities, 16.3% in sport, 4.5% of their waking hours in schoolwork, and 4.1% in other activities. Non-athlete student spent 33.2% in maintenance activities, 26.1% in discretionary activities, 24.7% in schoolwork, 9.8% in other activities, and 6.2% in sport. Both student athletes and non-athletes experienced more positive affect and motivation during discretionary activities, whereas more negative emotional states during schoolwork. Findings suggested that differences in student athletes’ and non-athletes’ daily life activity experience might lead to difference in socialization outcomes.

이 연구의 목적은 협동학습수업모형 적용이 학업성취에 미치는 영향을 조사하는 것이다. 중학교 1학년 체육교과 축구단원을 협동학습모형과 전통적 수업모형으로 나누어 수업 후 심동적, 인지적, 정의적 영역에 미치는 영향을 분석하였다. 이 연구에는 중학생 64명(협동학습집단 32명, 전통적 수업집단 32명)이 참여하였다. 심동적 영역의 학업성취를 평가하고자 실험학교인 H중학교의 축구단원 수업의 수행평가 항목을 이용하였고, 인지적 영역의 학업성취 평가는 교육과정 평가원에서 제시한 문항을 이용하여 측정하였다. 정의적 영역의 학업성취 평가는 20개 문항의 태도 질문지를 사용하였다. 연구결과, 첫째, 협동학습집단은 전통적 수업집단보다 심동적, 인지적, 정의적 학업성취, 즉 체육점수가 높게 나타났다. 둘째, 협동학습집단의 남학생들이 여학생들보다 학업성취가 높게 나타났다. 셋째, 협동학습은 학생들의 학업수준이 높거나 중간이거나 낮거나에 상관없이 학업성취에 효과적인 것으로 나타났다. The purpose of this study was to examine the effects of cooperative learning(CL) model on students' achievement in the seventh grade soccer unit. Participants were seventh grade students(N=64) in a middle school. Quasi-experimental design, nonequivalent control group design with pretest and posttest, was used for this study. Control group(n=32) received traditional teacher-directed instruction while the experimental group(n=32) used CL instruction. Data were collected by students' achievement test(i.e., soccer skill test, knowledge test, and students' attitudes toward PE) before and after the three week soccer unit. Overall, the results of three-way ANOVA showed that students working with CL instructional modelexhibited significantly higher scores in the achievement test(F(1, 52)=42.736, p<.001). More specifically, students in CL instruction model showed greater improvements than teacher-directed instruction in the psychomotor, cognitive and affective domain. Male students showed better achievement gains than Female students who had the same forms of instruction.

O-Wern Low,Tian Fu Loh,Hanjing Lee,Yan Lin Yap,Jane Lim,Thiam Chye Lim,Vigneswaran Nallathamby 대한성형외과학회 2022 Archives of Plastic Surgery Vol.49 No.1

Reconstruction of defects around the knee region requires thin and pliable skin. The superior lateral genicular artery (SLGA) flap provides an excellent alternative to muscle-based flaps. The anatomy and the surgical techniques of the SLGA flap were reviewed and the results of cases using the SLGA flap for coverage of knee and proximal leg defects were analyzed. SLGA flaps were performed in two cases and followed up for at least 6 months. Twelve articles on the use of the SLGA flap were also identified. A review of 39 cases showed that the mean diameter of the perforator supplying the skin of the flap was 1.04 mm, while the mean diameter of the SLGA at its origin was 1.78 mm. The mean length of the pedicle measured from the origin of the popliteal artery was 7.44 cm. The average dimensions of the flap were 14.8×6.6 cm with primary closure of the donor site in 61.5% of cases. Of these cases, 38.5% were due to trauma, 23.1% were post-burn complications, 12.8% were defects after resection of tumors, and 10.3% were for ulcers post-bursectomy. The most common complication was flap tip necrosis. All studies reported favorable outcomes with complete wound healing.
