Purpose: This is a report on the results of 150 consecutive cases of delayed postmastectomy reconstruction with TRAM flap performed by single surgeon. The purpose of this study is to review the merits, demerits and other considerations of this method by analyzing the results. Methods: From July 2001 to July 2008, 150 patients who had breast reconstruction by single surgeon were reviewed prospectively. Reviewed factors included demographic factors, mastectomy method, adjuvant therapies (such as radiation, chemotherapy) complication rate, simultaneous contralateral breast procedure rate, secondary touch - up procedure rate and patients’ satisfaction. Results: Ovarall TRAM flap complication rate was 22.6 %. Among them, donor site complication rate was 36 %, simultaneous contralateral breast procedure rate was 44.6 %, secondary touch - up procedure rate was 40 %. All rate was higher compared to immediate reconstruction with TRAM flap. But the patients’ satisfaction was about the same as immediate reconstruction. Conclusion: Delayed postmastectomy reconstruction with TRAM flap can yield satisfactory results despite relatively high complication rate and concomitant procedure rate when it is performed by a experienced surgeon.

대규모 대장암 데이터를 활용한 다중오믹스 데이터 통합 기법과 매개변수 분석

정인욱 한국정보과학회 2020 정보과학회논문지 Vol.47 No.8

Research is being conducted to reveal the mechanisms of diseases and organisms through analysis of genomic data including the expression information of genes. At the genomic level, the principles of living organisms or diseases are very complex, as there are many genes involved, and there is a sophisticated regulatory relationship between the genes. Additionally, various omics participate in the gene expression regulation. Recently, the volume of genome data generated yearly is rapidly increasing because of the decrease in the cost of next-generation sequencing. Various new technologies to measure multi-modal omics from one sample are in active development. In this study we conducted a parametric analysis on colon cancer multi-omics data to observe the effect of the sample number and omics objects on the classification of its four subtypes. Two well known multi-omics integration methods and our in-house built method were used for the analysis. As a result, we found that at least 100 samples and less than 5,000 omics objects were required to achieve a satisfactory subtype classification performance. Three different multi-omics analysis methods were compared. 유전자 발현정보를 포함한 다양한 유전체 데이터의 분석을 통해 질환과 생물체의 기작을 밝히기 위한 연구들이 활발히 수행되고 있다. 유전자 발현 조절 기작은 유전체 수준에서 수많은 유전자 간의 매우 정교하고 복잡한 관계에 의해 조절된다. 유전자 이외에 다양한 오믹스 또한 유전자 발현 조절에 관여한다. 최근 차세대 시퀀싱 비용의 하락으로 생성되는 유전체 데이터는 급속도로 증가하고 있다. 또한, 다양한 오믹스 데이터 생성을 위한 새로운 차세대 시퀀싱 기술들이 개발되고 있어 동일 생물체에 대해 여러 오믹스 데이터 측정이 가능하다. 본 논문에서는 제안하는 비음수텐서분해기법과 기존 다중오믹스 통합 기법들의 성능을 평가하고 데이터의 양 및 유전자 수와 같은 변수가 분석정확도에 미치는 영향력을 분석하였다. 대장암 데이터의 아형 분류를 위해 최소 100~150개 샘플과 5,000개 이하의 오믹스 개체가 필요한 것으로 분석됐다. 텐서분해기법이 가장 높은 분류정확도를 보였다.

This study aims to propose ESG (Environmental, Social, Governance) activities to shift perceptions within professional sports teams. Recently, there has been a notable increase in the ESG activities of professional sports teams, along with a diversification of these activities. However, existing ESG activities are primarily focused on social contributions, with some increase in environmental activities. Yet, there is criticism regarding the lack of a comprehensive approach to ESG initiatives. To achieve the research objectives, this study investigates the current direction of ESG activities in professional sports teams and employs in-depth interviews to address the established research questions. For the interviews, four experts, including professional sports team officials, and four sports fans who are directly engaged with the teams activities were selected. The interviews were conducted in a mixed format of face-to-face and virtual one-on-one sessions. For the first research question, a literature review of previous studies and in-depth interviews were conducted, revealing issues such as the absence of established ESG management committees and the exclusive focus on social contribution activities. Additionally, problems related to the improvement of eco-friendly facilities were identified. For the second research question, a thematic analysis method was employed for the in-depth interviews. This process highlighted the necessity for a broader range of ESG activities and presented various ESG initiatives based on this need, along with suggestions for future research.

단일 세포 분화 궤적 추론을 위한 시계열 다중 클러스터링 기법

장재연,정인욱 한국정보과학회 2022 정보과학회논문지 Vol.49 No.10

From time-series single-cell transcriptome data, gene expression information can be generated to observe the timing of significant cell differentiation changes while accounting for important biological phenomena in relation to experimental conditions. Due to recent surge of time-series single-cell transcriptome data, studies on various dynamic variation in cells such as cell cycle and cell differentiation have been actively conducted. Particularly, time series analysis at single-cell level for cell differentiation is advantageous for biological interpretation compared to a single time point as it is possible to observe changes in the time axis. In this paper, we proposed a multi-clustering method to infer cell trajectory by considering time information at the genetic-level of time-series single-cell transcriptome data. Analyses of gene expression data on the development of human neuron cell differentiation using this method showed similar results to biological results uncovered in a previous study. 시계열 단일 세포 전사체 데이터에서 유전자 발현 정보는 중요한 세포의 분화 변화 시점을 관찰하기 위해 생성되며 실험조건과 관련하여 중요한 생물학적 현상 설명이 가능하다. 최근 시계열 단일 세포 전사체 데이터가 급증함에 따라 세포주기 및 분화와 같은 세포의 다양한 동적인 변화에 대한 연구가 활발히 진행되고 있다. 특히, 세포 분화에 대하여 단일 세포 수준에서의 시계열 분석은 시간 축으로의 변화 관찰이 가능하여 단일 시점에 비해 생물학적 해석이 유리하다. 본 논문에서는 시계열 단일 세포 전사체 데이터를 활용해 유전체 수준에서 시간 정보를 고려하여 세포 궤적을 추론하는 다중 클러스터링 기법을 제안한다. 해당 기법을 사용해 인간 뇌세포 분화과정에 대한 유전자 발현 데이터를 분석한 결과 사전 연구에서 밝혀낸 생물학적인 결과와 유사한 결과를 찾아냈다.
