손태환,조욱상 학습자중심교과교육학회 2024 학습자중심교과교육연구 Vol.24 No.3
목적 이 연구는 생활체육 수영지도자들이 제공하는 피드백 유형이 참여자의 지도자 신뢰와 운동몰입에 미치는 영향을 분석하는데그 목적이 있었다. 방법 이를 위해 수도권에 소재한 생활체육 수영장에 등록되어있는 성인 350명을 대상으로 설문조사를 실시하였으며 변인 간 상관관계분석, 다중회귀분석, 매개효과분석을 진행하였다. 결과 본 연구 결과 첫째, 생활체육 수영지도자의 피드백 유형, 지도자 신뢰, 운동몰입은 유의미한 상관관계가 있었다. 둘째, 생활체육 수영지도자가 제공하는 피드백 유형은 참여자의 지도자 신뢰에 영향을 주는 것으로 나타났다. 셋째, 생활체육 수영지도자가 제공하는 피드백 유형은 참여자의 운동몰입에 영향을 주는 것으로 나타났다. 넷째, 생활체육 수영지도자의 피드백 유형과 참여자의 운동몰입 간 지도자 신뢰는 매개효과가 있었다. 결론 이상의 결과를 바탕으로 생활체육지도자의 피드백 유형은 생활체육 수영참여자의 지도자 신뢰, 운동몰입에 긍정적인 영향을주는 점에서 매우 중요한 요인임을 검증하였다. Objectives The Purpose of this study is to identify how much participants are satisfied and their exercise sustainability increases when sports for all instructors provide certain types of feedback. Methods The sampling methods used in the study is the judgment sampling which is the method of extracting samples after selecting sports for all swimming participants, who are currently enrolling in the swimming classes in Seoul, and distributed 320 questionnaires. In the actual analysis, the researcher analyzed 300 questionnaires excluding 20 questionnaires which were in discord with the question or missing some part of investigation contents. The analysis methods used in the study are SPSS 29.0 program and AMOS program. Frequency Analysis is used to analyze the respondents’ general characteristics. Exploratory factor analysis and reliability analysis are used to define the questionnaires about sports for all swimming instructors’ Feedback type, sports for all swimming participants’ instructors Trust and Sport Flow. Moreover, t-test and one way-ANOVA are used to identify the differences between these three variables. After that, correlation analysis is used to clarify correlations between three variables and which variables affect which variables. Results There was no significant difference in Sports for all swimming participants’ general characteristics by Sports for all swimming Instructors’ Feedback Type, Instructors Trust, and Sport Flow. The correlation of Sports for all swimming Instructors’ Feedback Type and Instructors Trust showed a positive correlation. Also, Instructors Trust and Sport Flow showed a statistically positive correlation. As a result of clarifying the effect of sub-factors of Sports for all swimming Instructors’ Feedback Type on sub-factors of Instructors Trust, it showed that positive general feedback performance knowledge feedback, and positive non-verbal feedback have an positive effect on sub-factors of Instructors Trust(p<0.05), while negative non-verbal feedback did not as well as in the analysis of The effect of sub-factors of Sports for all swimming Instructors’ Feedback Type on sub-factors of Sport Flow. As a result of analyzing the effect of sub-factors of Instructors Trust on sub-factors of Sport Flow, it appeared that diligence(p<0.023), openness(p<0.008), altruism(p<0.037) affecting cognitive commitment, and consistency(p<0.056) and ability(p<0.06) did not. Conclusions Firstly, there is no major difference on Instructors Trust and Sport Flow by gender, Sports for all swimming careers and frequency of exercise. Secondly, Sports for all swimming instructors’ Feedback Type has a partial effect on participants’ Instructors Trust. Specifically general positive feedback, performance knowledge feedback, and positive non-verbal feedback had a positive effect on consistency, ability and openness which are sub-factors of Instructors Trust, while negative verbal feedback had a negative effect on those three sub-factors. However, there is no effect on diligence and altruism, which are sub-factors of Instructors Trust, at all.
마이크로파 수분 측정장치를 위한 L대역 저잡음 증폭기 설계
손태환,정주수,주창복 경남대학교 신소재연구소 1995 論文集 Vol.5 No.-
본 논문은 유전율 2.54 두께 0.64[mm]의 테프론기판에 집중정수소자와 마이크로스트립 선로를 이용하여 주파수 0.8∼2.0[GHz]대역에서 이득 33±0.5dB, 잡음지수 1.0±0.2dB,이내, 입·출력반사 손실이 -10dB,이내의 동작특성이 우수하다고 생각되는 저잡음, 고이득 증폭기를 설계하였다. 설계사양에서 이득은 30dB,를 목표로 2단 증폭기로 구성하여 설계하고 최적화하였으나 최적화 시뮬레이션결과 이득은 33dB,에서 아주 놓은 이득평탄특성을 얻은반면 주파수 0.8∼0.9[GHz]부근세어의 출력측 반사손실이 다소 나쁜 결과로 나왔다. 그러나 반사손실 -5.8dB,이내에서는 전압정재파비가 1.64이하가 되므로 대체로 설계대역에서 만족할만한 결과가 얻어졌다고 생각된다. The low-noise amplifier(LNA) is designed and optimized using the microwave circuit CAD simulator, Harmonica. Considering the circuit size of amplifier. the microstrip lines and lumped elements are used properly on the teflon substrate (ε_{γ} = 2.54 , h = 0.64mm). The simulated experimental results show that gain is 33±0.5dB.noise figure is 1.0±0.2dB and the input, output return loss is generally less than -10dB over the frequency band of 0.8-2.0GHz. The gain is increased than the design goal of 30dB.but its simulation result showed very excellent operating characteristics. In case of return loss at frequency of 0.8-0.9GHz. it is also little increased but the return loss -5.8dB correspond to VSWR that of less than 1.6. In generally the designed low-noise amplifier is suitable for the microwave moisture measuring receiver module across the frequency band.
