COVID19로 인한 동호인 테니스 문화의 변화 : 수용된 문화를 중심으로

김민철,김한범 국민체육진흥공단 한국스포츠정책과학원 2023 체육과학연구 Vol.34 No.4

[목적] 본 연구에서는 해당 문화들이 어떻게 변화되었는지, 그리고 그 과정에서 테니스 동호인들이 어떤 경험을 하였는지를 살펴보았다. [방법] 연구참여자는 총 7명이며, 연구참여자는 모두 5년 이상의 동호회 참여경험, 2개 이상의 동호회 참여, 정기적 그리고 적극적으로 참여하고 있는 테니스동호인들이 참여하였다. 주로 심층면담을 진행하였으며, 원활한 심층면담을 위해 바구조화된 설문지를 활용하였다. [결과] 첫째, COVID19 이후 테니스동호인들은 비접촉 문화에 적응하였으며, 테니스동호인들은 이를 하나의 문화로수용하는 모습을 보여주었다. 둘째, 사회적 거리두기로 인해 많은 인원이 모이는 것이 어려워지자, 테니스 동호회 활동에 제한적으로 참여하게 되엇다. 그리고 이로 인해 이전과는 다른 좀 더 느슨해진 공동체 의식이 테니스 동호회 문화에 자리잡게 되었다. 셋째, 비대면콘텐츠에 대한 관심이 높아지면서 SNS를 통해 테니스를 즐기는 참여자들이 늘었다. SNS를 통해 얻은 정보와 경험은 코칭의 형태를 수동적인 모습에서 능동적인 모습으로 변화시키는데 기여하였다. [결론] COVID19로 인해 변화되어 테니스 동호인들에게 수용된 문화는 앞으로도 지속될 것으로 예상되며, 연구를 통해서 도출된 결과는 향후 변화되는 스포츠 문화에 대해 이해하는데 실마리를 제공할 수 있을 것이다. PURPOSE This study examined the cultural experiences of tennis club members that have changed due to COVID-19, specifically emphasizing the accepted culture within these clubs. METHODS Seven tennis club members, with over five years of experience, active participation in two or more clubs, and a history of active participation, were interviewed using in-depth interviews and a semi-structured questionnaire. RESULTS Firstly, the tennis club members accepted the “no contact” culture that has emerged since COVID-19. Secondly, social distancing made getting together in large groups difficult, and tennis club activities became more limited. This has led to weakening the tennis club community, which is different from what we have seen before. Lastly, the growing interest in non-traditional content has led to an increase in participants enjoying tennis through social media. The information and experiences gained through social media have changed the perception of coaching. CONCLUSIONS The cultures that tennis players have adopted due to COVID-19 are expected to continue in the future. The findings from this study may provide evidence for understanding the changing culture of sports in the future.

Chatbot service for providing the information of Oreum

김민철 제주대학교 관광과경영경제연구소 2019 産經論集 Vol.39 No.2

Jeju Oreum is a favorite tourist service among many Jeju Wellness activities. Based on this importance, information provision of Jeju Oreum can be regarded as a very important procedure of tourism service. In particular, This study is in the process of introducing a break-in period to protect Jeju Island. However, tourists and residents are aware of the situation of breaks by searching the Internet or contacting the person in charge for correct information. Therefore, this study suggested possibility of developing chatbot service as information providing service. Dialog Flow was used for this development, and Korean morphological analysis was performed using mecab morphoreme analyzer. In particular, I opened up Python using a Jupiter notebook and added items to the user dictionary by running a user prebuild script and Powershell. Through this procedure, this study finally presented a realization of user-based chatbot service. In the future, it is hoped to develop an improved deep learning based chatbot that links knowledge systems.

200 N급 GCH₄/LOx 소형로켓엔진의 형상설계와 성능시험평가 (Part II: 정상상태 지상연소시험)

김민철,김영진,김정수,Kim, Min Cheol,Kim, Young Jin,Kim, Jeong Soo 한국추진공학회 2020 한국추진공학회지 Vol.24 No.1

A performance evaluation of the 200 N-class GCH₄/LOx small rocket engine was performed through ground hot-firing test. As a result, the combustion pressure and thrust raised with the increase of the oxidizer supply pressure, and thus the specific impulse, characteristic velocity, and their efficiency increased. The characteristic velocity was measured at about 90% performance efficiency. The change of chamber aspect ratio did not affect the performance of the rocket engine in the test condition specified. In addition, uncertainty evaluation was conducted to ensure the reliability of the test results.

학대피해노인의 외상후 성장에 관한 구조모형연구

김민철,허준수 한국노년학회 2023 한국노년학 Vol.43 No.1

본 연구는 학대 피해 노인의 외상 후 성장에 영향을 미치는 요인 간의 관계를 구조방정식 모형을 통해 살펴보는 것으로Tedeschi와 Calhoun(2004)의 외상 후 성장이론을 토대로 학대 피해 노인의 자기 노출과 의도적 반추 그리고 사회적 지지가 외상 후성장에 미치는 직접, 간접효과와 변수 간의 구조 관계를 확인하고자 하였다. 본 연구는 전국 조사로 진행되었으며 17개 광역시도에설치된 지역노인보호전문기관을 통해 만 65세 이상의 피해 노인 303명을 대상으로 연구를 진행하였다. 분석방법으로 기술통계분석, 상관관계분석, 확인적요인분석, 구조방정식 모형을 활용하였고 이를 위해 SPSS 22.0 및 AMOS 22.0 통계프로그램을 활용하였다. 본연구의 결과는 다음과 같다. 직접효과에 대한 6개의 가설 중 5개 가설이 채택되었으며 1가지 가설이 기각되었고 간접효과에 대한3개의 가설 중 3가지 모두 지지 되었다. 채택된 직접효과를 살펴보면, 학대 피해 노인의 사회적 지지와 의도적 반추가 높으면 외상후 성장이 높은 것으로 나타났다. 그리고 자기 노출과 사회적 지지가 높으면 의도적 반추가 높은 것으로 나타났다. 또한, 자기 노출이높으면 사회적 지지가 높은 것으로 나타났다. 반면, 자기 노출은 외상 후 성장에 유의미한 직접효과를 나타내지 않았다. 간접효과를살펴보면, 의도적 반추는 자기 노출과 사회적 지지와 외상 후 성장 간의 영향을 매개하는 것으로 나타났다. 또한, 자기 노출과 외상후 성장 사이를 사회적 지지, 의도적 반추가 이중매개함을 확인하였다. 본 연구결과를 바탕으로 학대 피해 노인의 외상 후 성장을촉진하는 의도적 반추, 사회적 지지, 자기 노출을 향상시킬 수 있는 프로그램과 실천방안, 법률 및 제도 개선의 필요성을 제시하였다.

토양정화 공법 및 단위공정에 따른 토양건강성 평가

김민철,천미희,김정선,박민정,Kim, Mintchul,Chun, Mihee,Kim, Jungsun,Park, Minjeong 한국지하수토양환경학회 2021 지하수토양환경 Vol.26 No.6

The Soil Health Index (SHI) developed by Park et al. (2021) is used to evaluate soil health on remediated soils collected from several remediation project sites and monitored the changes of SHI during the remediation process of land farming, soil washing, and thermal desorption. In the case of land farming, the soils remediated below a legal standard didn't show any significant changes in indices of SHI except the downgrade of available phosphate from medium to a low level. The SHI scores were ranged from 52 to 56 in the contaminated soil and 54 to 57 in the remediated soil. With soil washing, bulk density changed from high to a low level, and available phosphate was lowered from medium to low level. As the SHI scores were evaluated as 58 to 63 for contaminated soil and 38 to 42 for remediated soils. For thermal desorption, soil respiration rate was reduced from high to low level and SHI was scored as 50 to 51 for contaminated soils and 43 to 47 for remediated soils. Even though any abrupt changes of the SHI in remediated soils were not identified in the soils used in this study, it is expected that soil in different conditions such as types and concentrations of contaminant and soil characteristics would result in distinguished changes of the SHI. There is a room for more studies collect diverse information on SHI across the country.
