The purpose of this study was to investigate the changes of flavor and taste characteristics of black pepper treated with three different nonthermal sterilization methods, which are intense pulsed light (IPL), ultraviolet (UV), and cold plasma (CP). Also, the sensorial and instrumental evaluation of black pepper before and after nonthermal treatments were analyzed. As a result of color value, UV and CP treatments did not show chromacity difference (ΔE), but IPL treatment showed a significant difference of 6.58. Piperine contents of sample before nonthermal treatments was 10.7±0.53 mg/g and the piperine contents of all samples decreased after nonthermal treatments. The result of the electronic nose analysis were divided into two groups before and after nonthermal treatments, and divided into three group by principle component analysis. According to the intensity test, after nonthermal treatments, all sample had low flavor and taste, and the intensity was in the order of IPL, CP, and UV. In thirteen sensory attribute languages developed through quantitiative descriptive analysis (QDA), the intensity value of the samples were low after nonthermal treatments.

The purpose of this study was to identify the relationships among academic self-efficacy, major satisfaction and career decision attitude of sport related majoring students. To achieve the purpose, 382 sport related majoring students were selected from universities in B city and Y city. Out of the 382 questionnaires responded to, only 316 were used for data analyses because 66 were responded to incorrectly. To process data, SPSS PC+25.0 Version statistical program for Windows were used and descriptive statistic, exploratory factor analysis, reliability analysis, correlation and standard multiple regression analysis were conducted. As the results, the following conclusion was derived. First, academic self-efficacy in sport related majoring students had a significant effect on major satisfaction. Second, academic self-efficacy in sport related majoring students had a significant effect on career decision attitude. Third, major satisfaction in sport related majoring students had a significant effect on career decision attitude. 이 연구의 목적은 체육계열 대학생들의 학업적 자기효능감과 전공만족도 및 진로결정태도의 관계를 구명하 는데 있었다. 이러한 연구목적을 달성하기 위하여 B시, Y시에 소재한 대학교 5곳에서 재학 중인 체육계열 대학생 382명을 편의표집방법(convenience sampling method)을 이용하여 표본을 추출하다. 수집된 자료는 Window용 SPSS 25.0 version을 이용하여 기술통계와 탐색적 요인분석, 신뢰도 분석, 상관관계분석, 표준중 다회귀분석(standard multiple regression analysis)을 실시하다. 이러한 연구방법과 절차를 통해 분석한 결론 은 다음과 같다. 첫째, 체육계열 대학생들의 학업적 자기효능감은 전공만족도에 유의한 향을 미친다. 둘째, 체육계열 대학생들의 학업적 자기효능감은 진로결정태도에 유의한 향을 미친다. 셋째, 체육계열 대학생들 의 전공만족도는 진로결정태도에 유의한 향을 미친다.
