This study examined the mediating effects of self-reassuring and self-attacking in the relationship between mental health and psychological well-being among college students. The study subjects were 230 (98 males and 132 females), and the collected data were analyzed using the SPSS PROCESS Macro based on regression analysis. The results of the study were as follows. First, there were significant relationship among mental health, psychological well-being, self-reassuring and self-attacking. Second, depression, obsessive compulsive disorder, interpersonal sensitivity and psychosis had a significant negative effect on psychological well-being. Third, self-reassuring and self-attacking had a partial mediating effect on the relationship between mental health and psychological well-being. The indirect effect of mental health on psychological well-being through self-reassuring was significantly higher than the indirect effect of psychological well-being through self-attacking. Based on the results of this study, we discussed the role of self-reassuring in the relationship between mental health and psychological well-being.

Objective: The purpose of this study was to verify the influence of educare teachers' self-encouragement and social support on their psychological burnout. Methods: This study was 329 educare teachers working in Jeju Special Self-Governing Province. The questionnaire for this study (self-encouragement scales, social support scales, and psychological burnout scales) was conducted and t-test, F-test, Turkey post test, Pearson Correlation analysis, simple regression analysis and multiple regression analysis was conducted by using the SPSS windows 18.0 program. Research results of analysis were as follows. Results: First, the difference of self-encouragement of educare teachers was remarkable according to age group and that of social support noticeable according to age group and career while that of psychological burnout was noticeable according to age group and marital status. Second, educare teachers' self-encouragement and social support has negative correlation with their psychological burnout. Third, educare teachers' self-encouragement and social support affect their psychological burnout in negative manner. In particular, self-encouragement functions, more than social support, as a main factor in reducing psychological burnout. Conclusion/Implications: These results can be utilized as basic data for developing education and counselling programs designed to provide emotional stability for educare teachers and help them give more positive child-care service.

자기저항헤드용 Ni-Fe-Co/Cu/Ni-Fe-Co/Fe-Mn 다층박막에서 자기적 성질과 전기적 성질에 관하여 조사하였다. 저 포화자계에서 고 자기저항을 나타내는 스핀 밸브형 다층박막을 제작하기 위하여 Borond이 도핑된 p-type Si(100)기판위에 Ni-Fe-Co 단층박막과 Si/Ni-Fe-Co/Cu/Ni-FeCo, Si/Ni-Fe-Co/Fe-Mn 구조의 다층막을 제작하여 자기적 특성을 조사하였다. Ni-Fe-Co 단층박막의 자기적 특성은 고정된 아르곤 분압에서 박막의 두께 등에 의존성이 있는 것으로 나타났다. 또한 Si/Ni-Fe-Co($70AA$)/Fe-Mn 구조에서 Ni-Fe-Co와 Fe-Mn 계면에서의 두 자성층의 이방성 차이에 의해서 발생되어지는 교환자기이방성이 존재하였으며, 교환자기이방성자계값은 Fe-Mn 두께가 $150\AA$일 때 가장 큰 값을 나타내었다. Ni-Fe-Co texture와 교환자기이방성자계값은 Fe-Mn 두께가 $150\AA$일 때 가장 큰 값을 나타내었다. Ni-Fe-Co texture와 교환자기이방성자계값의 의존성을 알아보기 위하여 Ti, Cu를 바닥층으로 사용하였다. Ti을 바닥층으로 사용하였을 경우, 교환자기이방성자계값은 23.5 Oe 정도의 가장 큰 값을 나타내었다. XRD 분석결과, Ti 바닥층이 Cu 바닥층이나, 바닥층이 없는 경우와 비교하여 성막된 Ni-Fe-Co 자성층의 강한 fcc(111) texture를 형성하는 것으로 나타났다. 각각의 단층박막과 다층박막에서의 자기적 특성을 측정한 후, Si/Ti($50\AA$)/Ni-Fe-Co($70\AA$)/Cu($23\AA$)/Ni-Fe-Co($70\AA$)/Fe-Mn(150$\AA$)/Cu(50$\AA$)의 스핀밸브구조를 갖는 다층박막을 제작하였으며, 11 Oe의 낮은 포화자계값에서 4.1%의 고 자기저항값을 얻을 수 있었다.

유기박막트랜지스터는 각 박막계면의 접촉성에 따라 그 성능이 좌우 된다는 것은 널리 알려진 사실이다. 이 때문에 계면간의 접촉성 및 결함을 최소화 하고 효율적인 패턴 형성을 위해 자기조립단분자막의 이용이 최근에 많이 시도되고 있다. 고품질 자기조립단분자막의 제작을 위해 RCA 세척을 통해 웨이퍼 표면에 OH기를 도입 보다 완벽한 단분자막의 형성을 촉진 하였으며 패턴제작은수분이엄격이조절된환경에서 alkyilsilane과 aminosilane 자기조립단분자막을 각각 ${\mu}CP$과 용액공정을 통해 시도되었다. 이 과정에서 물리적 흡착이나 OH기 부족으로 생성된 결함을 보안하기 위하여 SC1용액을 사용 단순 물리흡착된 자기조립단분자 물질의 제거와 다시 OH기 도입 용액공정을 통해 자기조립단분자막 형성을 반복적으로 실시하였다. 그 결과 자기조립단분자막의 결함이 최소화 되었고 자기조립단분자막의 질에 따라 유기전극재료 증착 시 선택적인 성장 과 형성된 유기전극재료 층의 형상이 다르게 관찰 되었다. 이런 반복적인 용액공정을 통해 결함이 최소화된 고품질 자기조립단분자막은 박막계면 간 옴성접촉을 형성하여 유기박막트랜지스터 제작 시 성능 향상이 기대되어진다.

한 시계열의 자기상관계수의 절대값을 시차를 무한대로 접근시켜 가면서 각 시차에 대하여 구하고 이 절대값을 모두 더한 값이 무한일 때 이 시계열은 장기기억을 가진다. 이로 인하여 장기기억 모수를 추정하는데에는 자기상관을 기본으로 한다. 표본의 자기상관과 이론적 자기상관 사이의 거리를 최소하여 추정통계량을 유도하고 있는 것이 일반적이다. 이 경우에는 정상적 과정에 한하여 적용이 가능하다. 시계열은 어느 시계열이던지 간에 이 시계열에 적합한 모형이 존재할 것이고 이 모형을 시계열에 적용하면 잔차 시계열을 얻을 수 있다. 원래 시계열의 이론적 상관 대신 원래 시계열의 잔차 시계열의 자기상관과 표본의 자기상관 사이의 거리를 최소하여 추정통계량을 얻으면 통계량의 계산이 편하고 이 추정량은 정상적 시계열과 비정상적 시계열에 다같이 적용할 수 있다. 본 논문에서는 잔차의 자기상관을 이용하여 자기회귀 분수적분 이동평균 과정의 모수 추정량을 도출한다. 그리고 이 추정 통계량에 입각하여 주가의 형성과정을 살펴보고 장기기억이 옵션가격과 포트폴리오 구성에 미치는 영향을 밝힌다.

Magnetic and physical properties of sintered bodies prepare from waste sintered barium hexaferrite magnets which were come from fabrication process of isotropic permanent magnets were investigated. The properties of the sintered bodies were characterized by XRD, XRF, SEM, and BH curve tracer. After the waste permanent magnets were milled and granulated, the granules of the waste permanent magnet powders and the commercial granules were mixed with various proportions, pressed, and sintered. although the magnetic properties were decreased gradually with the content of waste magnet powder, the magnetic characteristics of the sintered magnets at $1150~1200^{\circ}C$ were comparable to those required for isotropic permanent magnets.

The purpose of this study is to examine the mediating effect of perception of society and evaluation of oneself in the relationship between self-compassion and life satisfaction. A survey was conducted on 215 full-time workers along with self-compassion scales, life satisfaction scales, social well-being and core self-evaluation. As a result of the study, social well-being and core self-evaluation completely mediated the relationship between self-compassion and life satisfaction, and the difference of indirect effects between social well-being and core self-evaluation was not significant. These results show that the effect of self-compassion improving life satisfaction can be explained through social well-being and core self-evaluation. The implications and limitations of this study for future research were discussed.

This study was conducted to investigate learning motivation, communication skill, academic self-efficacy which influence self-directed learning ability in nursing students. A total of 194 second year students were recruited from nursing department in Gwangju. Structured questionnaire was self-administrated from November 2 to 30, 2015. In self-directed learning ability, there were significant differences in gender, personality disposition, applied motivation, satisfaction on major, satisfaction of campus life, and school grade. In multiple regression analysis, learning motivation, communication skill, academic self-efficacy, satisfaction on major and school grade were significant factors of self-directed learning ability explaining 53.1% of the variables. In conclusion, to enhance self-directed learning ability for nursing students, it is necessary to develop program and curriculum for increasing learning motivation, communication skill, and academic self-efficacy.

The purpose of this study was to investigate the mediating effect of academic self-efficacy in the relationship between self-management competency and employment preparation behavior of senior nursing students. The data were analyzed using SPSS 26.0 program, frequency analysis, t-test, ANOVA, Pearson's correlation, and multiple regression. As a result of the study, self-management competency was positively correlated with academic self-efficacy, employment preparation behavior, and academic self-efficacy with employment preparation behavior. Academic self-efficacy showed a partial mediating effect between self-management competency and employment preparation behavior. The higher the level of self-management competency and academic self-efficacy, the higher the level of employment preparation behavior, and the explanatory power (R²) was 34%. Therefore, it suggests that it is important to develop self-management competency and to prepare an integrated strategy that can induce a sense of academic self-efficacy in order to promote the employment preparation behavior of nursing students.
