체육계열 대학생의 입학경로 유형 및 특성에 따른 대학생활 만족에 관한 연구
김성덕 ( Kim Sungduck ) 한국체육대학교 체육과학연구소 2020 스포츠사이언스 Vol.38 No.1
The purpose of this study is to analyze the types of entrance paths of college students in physical education and to analyze the differences in college life satisfaction according to the characteristics of college students in physical education. In order to achieve the above research objectives, a total of 345 physical education college students' questionnaire data were subjected to descriptive statistics, one-way analysis of variance, and Chi square analysis to obtain the following results. First, a college student in the department of physical education applied for a job in the sports industry or hoping to become a physical education teacher, and also chose physical education as an area suitable for his or her aptitude and talent. In particular, the main influence of the decision to enter the university was influenced by parents, family members, school teachers, sports officials, friends and seniors. Second, college students in the department of physical education usually prepare for entrance exams in the second and third grades of high school through cram schools at specialized sports colleges, and spend at least 300,000 won and up to 600,000 won. Third, in terms of university life satisfaction according to the characteristics of college students in the sports category, there were partial differences in university life satisfaction depending on gender, grade, entrance examination, average grade, location area and whether they went to the university they wanted. Therefore, there is a need for discussions on the selection of college students in the sports field, systematic career setting and academic management.

The purpose of this study is to investigate the relationship between Perceived Organizational Support, exercise satisfaction and exercise commitment of student athletes. In order to achieve this goal, student athletes registered with the Seoul City Sports Council were the population, which were surveyed from March to May 2020. Specifically, most participants were student athletes studying National Sport University, and some of which were middle and high school student athletes. A total of 400 student athletes were sampled using convenience sampling method, but 306 were finally used in the data analysis excepting incomplete or faithless questionnaires. the data analysis was conducted through frequency analysis, Cronbach's α, Confirmatory Factor Analysis (CFA), correlation analysis and Structural Equation Model (SEM) using SPSS 20.0 and AMOS 20.0. As a Result; Firstly, Perceived Organizational Support of student athletes positive had a significant effect on exercise satisfaction and exercise commitment. Secondly, exercise satisfaction positive had a significant effect on exercise commitment. Therefore, supervisors need to closely manage the Organizational Support of student athletes.

코로나-19 팬데믹으로 인한 체육전공 대학생의 교수실재감, 온라인 수업 만족도, 인지된 학업 성취도 및 지속참여의사의 관계
김성덕 ( Sungduck Kim ),김주영 ( Jooyoung Kim ) 한국체육대학교 체육과학연구소 2021 스포츠사이언스 Vol.39 No.2
The purpose of this study was to investigate the relationship between teaching presence, online lectures satisfaction, perceived learning outcomes, and intention to continue participating in physical education college students due to the COVID-19 Pandemic. In order to achieve this goal, we selected 400 college students who took online classes using convenient sampling methods and conducted a reliable survey of 357 students. 357 were finally used in the data analysis excepting incomplete or faithless questionnaires. the data analysis was conducted through frequency analysis, Cronbach's α, Confirmatory Factor Analysis (CFA), correlation analysis and Structural Equation Model (SEM) using SPSS 21.0 and AMOS 21.0. Technical statistics and frequency analysis were conducted to identify the form of non-face-to-face classes. Recording lectures were the highest, followed by video conferencing (Zoom, Meet, etc.) and recording and providing the entire video of the professor's lecture. The results are as follow: Firstly, teaching presence positive had a significant effect on online lectures satisfaction. Secondly, online lectures satisfaction positive had a significant effect on perceived learning outcomes. Thirdly, online lectures satisfaction positive had a significant effect on intention to continue participating.

체육전공 대학생의 블렌디드-PBL 기반 진로교육 효과성 연구
김성덕 ( Sungduck Kim ) 한국체육대학교 체육과학연구소 2021 스포츠사이언스 Vol.39 No.3
The purpose of this study is to investigate the effectiveness of blended-PBL-based career education for students majoring in physical education. In order to achieve this purpose, 40 subjects who participated in class A were selected and surveyed from March to June 2021 among the physical education majors at the university located in C city. Finally, the data of 37 people who submitted the assignment were used for the study. Next, the research process was conducted on a weekly basis. After the first and second career preparation behavior tests and core theory lectures, Holland tests and disc behavior type tests were conducted. And the pre-post-analysis of the career preparation behavior test was conducted based on SPSS. The results are as follows. First, in the Holland test and disc behavioral type test of college students majoring in physical education, the occupational group with professional social and social characteristics was desired, and the social type type was high. Second, it was found that career preparation behavior increased statistically significantly after blended-PBL education. Therefore, it is estimated that career education based on self-directed learning is necessary based on sufficient self-understanding of college students majoring in physical education.

K-NN 측위 방법과 Bayesian 측위 방법의 실험적 비교 분석
임재걸 ( Jaegeol Yim ),김성덕 ( Sungduck Kim ) 한국정보처리학회 2006 한국정보처리학회 학술대회논문집 Vol.13 No.2
옥내 위치기반서비스(LBS : Location Based Service)를 제공하려면 옥내에 있는 사용자의 위치를 정확히 측정하는 것이 중요하다. 옥내 측위 방법으로는 UDP 패킷의 신호 세기를 이용한 RADAR 방법, 적외선을 이용한 Active Badge, RF(Radio Frequency)와 Ultrasound를 이용한 Cricket 방법이 있다. 기존의 이러한 방법들은 모두 측위만을 위한 특수 장치가 설비되어야 측위가 가능하다. 즉, RADAR에서는 측위를 위하여 base station (desktop computer)과 통신을 하여야 하며, Active Badge에서는 방마다 적외선을 수신하는 장치가 있어야 하고, Cricket에서는 천정에 센서를 설치해야 한다. 본 논문에서는 이미 설치되어 있는 무선랜용 AP로부터 수신되는 신호의 세기(RSSI)를 이용함으로 측위만을 위한 특수 장비가 필요 없는 경제적인 측위 방법을 제안한다. 측위 알고리즘으로 RADAR에서 사용한 K-NN(K-Nearest Neighbor) 방법과 Bayesian classification 방법을 구현하여 두 가지 방법의 성능을 비교하는 실험을 수행 한다.

무한장 도체를 삽입한 솔레노이드 코일의 전자기적 특성의 해석
김성덕,심재명,정재기 大田産業大學校 1994 한밭대학교 논문집 Vol.11 No.0201
This paper dealt with electro-magnetic properties in the solenoid coil. Flux density of the solenoi coil is represented in the form of zero and first order function by the using Bessel function. In the case of the conducting rod inserted in the solenoid coil, the variation of the impedance due to the flow of the eddy current on the rod is investigated, The variations of magnetic permeability and fill factor is considered in the computer simulation. The simulation result of impedance variations with repect to the frequency variations in the case of nonferromagnetic rod and ferromagnetic rod is presented.
