The purpose of this study was to investigate whether sperm selection by hyaluronic acid (HA) binding could improve fertilization rate and embryo quality in intracytoplasmic sperm injection (ICSI) cycles. Two hundred nineteen oocytes obtained from eighteen women were injected with either HA-bound (n = 107) or conventionally selected spermatozoa (n = 112)in a randomized way. All of the participants were infertile couples who had normal sperm parameters but low fertilization rate in previous in vitro fertilization (IVF) cycle (n = 5) or experienced multiple IVF failures (n = 13). Lower fertilization (75.7% vs 83.0%) and cleavage rate on day 2 (72.9% vs 83.0%) was observed in oocytes injected with HA-bound spermatozoa than the conventional group, but the difference was not significant. Significantly lower cleavage rate was observed on day 3 in HA group (56.0% vs 69.6%,P = 0.038). Blastocyst formation rate and the number of transferred embryos were similar in both groups. In multiple IVF failure patients, significantly reduced fertilization rate (71.8% vs 85.3%, P = 0.046) and cleavage rate on day 2 (70.4% vs 85.3%, P = 0.029)and day 3 (53.5% vs 77.3%, P = 0.002) were noticed in HA group. Five women achieved pregnancy continuing more than 12 weeks after transfer (27.8%). Success of ICSI was not related with the number of embryos fertilized by HA-bound spermatozoa. Application of ICSI by sperm selection using HA binding is not helpful in couples with repeated poor fertilization or implantation despite normal sperm parameters.

패럴림피언의 삶의 기록: 장애인 탁구 패럴림피언을 중심으로

최승아,김지훈 대구대학교 한국특수교육문제연구소 2023 특수교육저널 : 이론과 실천 Vol.24 No.3

[목적] 본 연구는 세계적으로 장애인 탁구 종목에서 뛰어난 성장과 성과를 올리고 있지만, 여전히 일반 대중에게는 관심에서부터 소외되고 있는 장애인 탁구 대표팀의 패럴림픽 참가 경험과 그 경험이 의미하는 것은 무엇인지 살펴보는 것에 있다. [방법] 탁구 패럴림픽에 참가한 경험을 가진 연구 참여자들의 심층 면담 과정을 통해 패럴림픽 출전과정은 어떻게 되는지? 패럴림픽에 출전해서 입상까지 과정은 어떻게 되는지? 패럴림픽이 패럴림피언들에게 삶의 어떠한 의미를 부여하고 있는지 시기별로 분류하고, 이야기되는 맥락을 분석하여 해석을 도출하였다. [결과] 연구 결과는 다음과 같다. 첫째, 참여자 모두 군대에서 불의의 사고로 원치 않은 장애를 얻었고, 재활을 위해 탁구를 접하게 되면서 장애가 생긴 그들에게 다시 살아갈 수 있게 한 희망이 된다. 둘째, 패럴림픽 참가는 시간과 비용뿐만 아니라 무관심과 차별, 장애의 고통까지 극복해야 하는 일이었다. 셋째, 패럴림픽 챔피언이 된 이후 그들의 운동여건은 개선되고 있지만, 여전히 그들은 생활고를 신경 쓰고 있었다. [결론] 여전히 관심도 부족하고 지원도 턱없이 부족한 상황을 이겨내며 패럴림픽을 준비하는 장애인 체육인들에 관한 실질적인 지원에 더불어 언론을 비롯한 우리들의 더 많은 관심이 필요하다. [Purpose] This study aims to examine the Paralympic participation experience of the disabled table tennis team, which is still marginalized from interest to the general public, and what it means. [Method] What is the process of participating in the Paralympics through in-depth interviews with research participants who have participated in the table tennis Paralympics? What is the process of participating in the Paralympics and winning a prize? The meaning of life of the Paralympics was classified by period and the context of the story was analyzed to derive an interpretation. [Results] The results of the study are as follows. First, all participants gained unwanted disabilities due to unexpected accidents in the military, and as they encountered table tennis for rehabilitation, it is a hope that they can live again. Second, participation in the Paralympics had to overcome not only time and cost, but also the pain of indifference, discrimination, and disability. Third, their athletic conditions have been improving since they became Paralympic champions, but they were still concerned about their hardships. [Conclusion] We need more attention from the media and others, along with practical support for disabled athletes preparing for the Paralympics while overcoming the still lack of interest and support.

엘리트체육인의 삶과 폭력의 대물림

최승아,윤대중,김지훈 한국구술사학회 2019 구술사연구 Vol.10 No.1

The purpose of this study is to find out how an athlete's life affects his or her identity as a student, and how this formed identity changes as a leader. According to the study, violence exerted by leaders and seniors within the Ministry of Exercise and discrimination at schools affected the identity of the study participant. As the leader of the high school athletic department, he used the violence he learned, starting the reproduction of the violence. The research participant, who became university athletic director, went through a change of perception due to reflection on his graduate education and discontinued the reproduction of violence by changing his behavior. The study revealed that violence within the athletic department continued in tacit consent and advocacy of schools, leaders, and parents. It was also known that a student athlete who learned violence would reproduce it when he or she later became a leader. To end such violence, professional leader education, especially leader personality education, must be provided, and strong punishment for violence must be made. 본 연구는 학생선수로 시작하여 현재는 지도자의 길을 걷고 있는 한 인물의 삶에대한 경험과 기억을 현재의 구술을 통해 학생선수가 어떠한 정체성을 형성하게 되고, 지도자의 길을 걷게 되면서 그 정체성이 어떻게 변화되는지에 대해 알아보는데 목적이 있다. 연구결과 참여자는 운동부 안에서 지도자와 선배로부터 받은 폭력과 학교에서 받은 차별이 정체성 형성에 영향을 미쳤고, 고등학교 지도자가 되어서는 학습된폭력이 표출되면서 폭력의 대물림이 이뤄졌다. 이후 대학교 지도자가 된 참여자는 대학원 교육을 받으면서 반성을 통해 인식의 변화를 겪었고, 그 결과 폭력의 대물림을끊게 된다. 본 연구를 통해 운동부 내에서 이루어지는 폭력이 학교, 지도자, 부모의 암묵적 동의와 옹호 속에서 지속했던 것이 드러났고, 폭력을 학습한 학생선수가 훗날 지도자가되면서 폭력을 대물림하는 것도 알 수 있었다. 이러한 폭력의 단절을 위해서는 전문지도자교육, 특히 지도자 인성교육을 실시해야 하며, 폭력에 대한 강력한 처벌이 이루어져야 한다.

Causes of Child Mortality (1 to 4 Years of Age) From 1983 to 2012 in the Republic of Korea: National Vital Data

최승아,조성일 대한예방의학회 2014 Journal of Preventive Medicine and Public Health Vol.47 No.6

Objectives: Child mortality remains a critical problem even in developed countries due to low fertility. To plan effective interventions, investigation into the trends and causes of child mortality is necessary. Therefore, we analyzed these trends and causes of child deaths over the last 30 years in Korea. Methods: Causes of death data were obtained from a nationwide vital registration managed by the Korean Statistical Information Service. The mortality rate among all children aged between one and four years and the causes of deaths were reviewed. Data from 1983-2012 and 1993-2012 were analyzed separately because the proportion of unspecified causes of death during 1983-1992 varied substantially from that during 1993-2012. Results: The child (1-4 years) mortality rates substantially decreased during the past three decades. The trend analysis revealed that all the five major causes of death (infectious, neoplastic, neurologic, congenital, and external origins) have decreased significantly. However, the sex ratio of child mortality (boys to girls) slightly increased during the last 30 years. External causes of death remain the most frequent origin of child mortality, and the proportion of mortality due to child assault has significantly increased (from 1.02 in 1983 to 1.38 in 2012). Conclusions: In Korea, the major causes and rate of child mortality have changed and the sex ratio of child mortality has slightly increasedsince the early 1980s. Child mortality, especially due to preventable causes, requires public health intervention.

견관절 전산화단층촬영 관절조영술과 자기공명 관절조영술의 비교: 견관절 관절순인대 열상의 진단

최승아,차장규,홍현숙,최득린,박재성,이혜경,김대호 대한영상의학회 2007 대한영상의학회지 Vol.57 No.5

Purpose: To compare the accuracy of 16-slice multi-detector row computed tomographic arthrography (MDCTA) and magnetic resonance arthrography (MRA) for making the diagnosis and classification of labroligamentous injuries. Materials and Methods: This study is a prospective series that used MRA and MDCTA to examine 23 patients who complained of shoulder instability. Two radiologists independently analyzed the MRA and MDCTA. The sensitivity, specificity, accuracy, positive and negative predictive values were calculated from the arthrograms and the arthroscopic findings. The images of MDCTA and MRA corresponded with the findings on arthroscopy. Results: Both imaging modalities had the same sensitivity for detecting Bankart lesions (n=10, 90%) and posterior labral tears (n=2, 50%) on McNemar test (p=1.00). For superior labrum anterior-to-posterior (SLAP) lesions, 6 MRA cases and 4 MDCTA cases corresponded with the arthroscopic findings. The difference between the sensitivities of MDCTA (66.7%) and MRA (100%) was not significant (p=0.09). Conclusion: We suggest that the sensitivity of diagnosing labral lesions that induce shoulder instability is similar for MDCTA and MRA. MDCTA is effective for diagnosing and evaluating shoulder instability. 목적: 관절순인대 열상의 진단을 위한 16 slice 전산화단층촬영 관절조영술(16-slice multi-detector row computed tomographic arthrography; MDCTA)과 자기공명 관절조영술(magnetic resonance arthrography; MRA)의 진단율을 비교한다. 대상과 방법: 견관절 불안정성을 호소하는 23명의 환자를 대상으로 MRA와 MDCTA를 모두 시행한 후 수술적 관절경으로 병변을 확인하였다. 두 명의 영상의학 전문의가 개별적으로 MRA와 MSCTA를 판독하여 견관절 불안정성을 유발하는 병변의 유무를 기술하였다. 관절경 소견을 기준으로 각 검사의 민감도, 특이도, 정확도 및 양성예측도와 음성예측도를 구하고 McNemar test를 이용하여 민감도 차이를 비교하였다. 결과: 관절경에서Bankart variant를 제외한 15 개의 견관절 중 3 개에서 두 가지 병변이 혼재하여, 총 18예의 병변을 확인하였다. Bankart lesion과 posterior labral tear의 진단에서 MRA와 MDCTA의 판독결과는 일치하였다. 결과적으로 McNemar test를 이용한 통계분석에서 MRA와 MDCTA의 유의한 민감도 차이는 없었다. 결론: 견관절 불안정을 유발하는 관절순인대 열상의 질환에서, MDCTA의 진단율은 MRA의 진단율에 상당히 근접하여, 진단에 유용하게 사용할 수 있다.
