  • 최근 세계적으로 환경보호에 대한 관심이 고조됨에 따라 기술개발 방향이 환경을 고려한 규정 및 장치에 제한을 받고 있다. 따라서 냉동 공조 기기에 사용되는 기존의 CFC계열 냉매가 오존층 파괴의 주 원임이 판명됨에 따라 환경 문제가 없는 HCFC계열인 R123와 HFC R134a로의 대체가 불가피하게 되었다.

  • 현대사회의 의료 시술 중 부작용이 거의 없으며 배우기 쉬워 일상적으로 널리 사용되고 있는 의료형태를 대체의학이라 한다. 많은 선진국에서 미래형 의료 서비스로 대체의학에 관한 연구를 활발히 진행하고 있다. 대체의학은 종류가 많지만 그 중 귀에 몸의 각 부위가 상응하는 반사점이 있으며 이를 자극하여 치료하는 형태를 이침요법(耳針療法)이라 한다. 본 논문에서는 이러한 이침요법(耳針療法)을 사용하여 폐에 상응하는 이혈 반사점을 자극하였을 때 음성의 변화를 분석하는 실험을 수행하였다. 이를 위해 폐 이혈(耳穴) 자극 전과 후의 음성을 수집하고 기존 연구를 기반으로 폐와 연관성이 있는 음성분석 요소인 발화속도, Intensity 기술을 적용하여 변화 지표를 측정하고 이를 분석하여 이혈요법의 효과를 입증하는 연구를 수행하였다.

  • The participants were 102 students with digital broadcasting and media major.. A hypothetical model proposed included learning flow, school support as predictors, and satisfaction and learning persistence as a criterion. The results of this study through multiple regression analysis indicated that learning flow and school flow predicted significantly on satisfaction. And school flow, school support, and satisfaction predicted significantly on learning persistence. In addition, satisfaction mediated between learning flow and learning persistence, and between school flow and learning persistence. A constructive foundation for providing learning strategies in the successful engineering education would be proposed on the basis of the current results of this study.

  • The purpose of this study is to analyze work values of undergraduates according to major and gender. The result of this research is following. First, undergraduates from engineering and social science department took a very serious view of achievement and leasure of body and mind in work values. Second, undergraduates made much of achievement, job stability, leasure of body and mind, economic compensation and reputation. And undergraduates thought that internal value orientation was more important than external value orientation. Third, two groups had significant difference in service, knowledge pursuit, patriotism, economic compensation, reputation, and indoor activity. Fourth, the result of this analysis according to gender is following. Male undergraduates made much of leasure of body and mind, achievement, job stability, knowledge pursuit, and economic compensation in order. But female undergrduates made much of economic compesation, leasure of body and mind, achievement, and job stability in order. Fifth, that undergraduates make little of domain of service and patriotism gives a suggestion as to improvement of course education. As a result, this study is suggestive of instruction and advice in course search curriculum.

  • 설계홍수량의 유도를 위해 일차적으로 극치계열인 금강, 영산강 및 석진강 수개 3개 유역의 연최고치계열을 중심으로 하여 SMEMAX법, 역변환(Power Transformation) 및 2단계역변환(Two step Power Transformation, TSPT)법에 의해 척도분포의 정규화를 위한 변환법의 효율성 검정과 설계홍수량의 유도 및 비교분석을 수행한 결과 SMEMAX 법과 Power 변환법에서는 정규분포화를 왜곡도계수의 영으로의 접근 시도는 가능하나 소설도, 3으로의 조건을 충족시킬 수 없었던 반면 2단계역변환법에서는 소설도, 3에 매우 근접된 결과를 가져오므로서 척도분포의 정규화를 기할 수 있었고 각각의 변환법에 유도된 설계홍수량간의 비교분석에서는 SMEMAX 및 Power 변환법에 비해 2단계역변환방법에 의한 설계 홍수량이 재현기간 10년 이상 실측치에 보다 접근된 좋은 결과를 나타내었다.

  • In order to analyze the influence of subjective cognition about determinant factors in employment on job satisfaction, this study utilized The Graduates Occupational Mobility Survey(GOMS) 2010 Year and the subjects of this survey were 4,051 people who graduated from university. The results of this study were follows: First, subjective cognition about determinant factors in employment and job satisfaction were showed significant difference by gender, type of school, school location, major fields. Second, school in region, education major, the academic factor, the certification & major field factor, the personality & human connection factor were found to have positive(+) influence on the intrinsic satisfaction. Third, 2~3years college, school in region, social major, education major, technology major, natural major, medical major, academic factor, the certification & major field factor, the personality & human connection factor were found to have positive(+) influence on the extrinsic satisfaction. This study provides detailed analysis on subjective cognition about determinant factors in employment, offering new verification of work job satisfaction.

  • This study researched methods for coping with safety accidents by university students, after considering the situation of safety education by universities in Korea. For this study, a survey of 411 students of universities in the cities of Gwangju and Daejeon was conducted. According to the results, the ratio was high for answers such as willingness to participate in safety education beginning with the departments of engineering, art and physical training, education, art and humanity, social sciences and natural sciences, and medical sciences. It was found that university students most preferred first aid among the contents of safety education. University students of all departments answered that they had experienced safety education, but were afraid to be embarrassed in the case of actual safety accidents, as was found through the results of investigations of their awareness of coping methods with safety accidents. It was verified that many times their suffered skin and other wound in an earlier safety accident that they had experienced. This study suggests that safety education needs to be accomplished in the university curriculum, predicting and practicing for causes and factors of danger in advance, in order to improve the level of safety awareness and safety competence among university students.
