Purpose: The purpose of this study was to review journal articles, master's theses, and doctoral dissertations on self-leadership in nurses in order to identify overall trends in nursing self-leadership and to suggest strategies to improve self-leadership. Methods: Twenty-six papers on self-leadership in nurses were reviewed. Results: These papers were journal articles, master's theses, and doctoral dissertations regarding nurses who worked in general hospitals, university hospitals, and public health centers. Self-leadership was measured by using instruments developed by Manz (1983), Prussia, Anderson, & Manz (1998), and Houghton & Neck (2002). The instrument was composed of 18 items, with a 5-point Likert scale developed by Manz (1983) and modified by Kim (2002). Nurses' self-leadership was found to be related to job satisfaction, organizational commitment, nursing performance, and citizenship behavior. General characteristics of nurses, including age, education, marital status, position, and career, were also associated with self-leadership. Conclusion: The study findings provide data on recent trends in nurses' selfleadership. These results serve as basic data to provide a standard for developing self-leadership and indicate directions for further research.

리더십이란 조직을 이끌어 가기 위해 발휘하는 능력이라고 정의할 수 있다. 최근 산업계뿐만 아니라 학계 등에서는 리더십 관련 연구에 관심이 고조되고 있다. 리더십의 종류에 따라 조직의 성격과 문화, 생산성 등에 많은 영향을 미칠 수 있기 때문이다(Manz와 Sims, 1987). 리더십과 관련한 많은 연구들은 주로 경영학 분야뿐만 아니라 산업심리 혹은 심리학 분야에서도 많은 관심을 보이는 연구 분야다. 특히 최근에는 셀프리더십(self-leadership) 관련 연구가 학계, 산업계에서 더 많은 관심이 모아지고 있다. 본 연구는 정보기술(information technology)관련 과목을 수강하고 있는 대학재학중인 학생들의 셀프리더십 정도가 학업성과에 어떤 영향을 미치는 지를 연구하고 한다. 연구의 결과는 대학생들의 셀프리더십을 고양하므로써 학업성과를 촉진할 수 있는지 여부에 대해 시사점을 줄 수 있을 것이며, 나아가 기업의 생산성을 제고할 수 있는 리더십 프로그램 개발에 도움을 줄 것이다.

This study was conducted to investigate a correlation of factors that have an influence on the happiness of college students, and to investigate the effect of factors on happiness of college students by analyzing the structure of influencing factors of happiness. To this end, 430 freshmen in college were selected and tested on character, self-esteem, self-leadership, and happiness. The measurement tools used in this study were the 30 questions of Character Scale that Choi Min-Soo and Im Eun-Young(2013) developed and modified by Im Eun-Young(2015), a Self-Leadership Scale of Manz(1998) classified into behavioral strategy and cognitive strategy that Wang Ji-Seon(2011) translated and modified. a Self-Esteem Scale(SES) of Rosenberg(1986) that the researcher modified and used, and The Oxford Happiness Questionnaire of Hills and Argyle(2002) that Choi Yo-Won(2002) translated and the researcher modified. According to the research result, for correlation with happiness, self-esteem was .86, self-leadership was .74, and character was .66, and for correlation with self-leadership, character was .70, self-esteem was .66, and correlation between character and self-esteem was .57. Secondly, for direct effect on happiness, self-esteem was .62, character as .20, self-leadership was .19, and for direct effect on self-leadership, character was .49 and self-esteem was .38. Thirdly, indirect effect of character on happiness through self-leadership was .94 and indirect effect of self-esteem on happiness through self-leadership was .73. Through these research results, it was identified that character, self-esteem, and self-leadership of college students are the influencing factors on happiness, and that self-esteem is the biggest influencing factor on happiness of college students among the three variables. The results of this study suggested that university students' personality had a positive relationship with self-esteem and that university students' personality, self-esteem, and self-leadership altogether had a direct influence on happiness. Moreover, both personality and self-esteem of university students had an indirect influence on happiness through their self-leadership.

Fluorescent probes bound to DNA typically display nanosecond decay times and reveal only nanosecond motions. We extend the time range of measurable DNA dynamics using $[Ru(pby)_2(dppz)]^{2+}$ (bpy=2.2'-bipyridine, dppz=dipyrido[3,2-a2',3'-c]phenazine) (RuBD) which displays a mean lifetime near 90 ns. To test the usefulness of RuBD as a probe for diffusive processes in calf thymus DNA, we compared the efficiencies of fluorescence resonance energy transfer (FRET) using three donors which display lifetimes near 5 ns for acridine orange (AO), 22 ns for ethidum bromide (EB) and 92 ns for RuBD, with nile blue (NB) as the acceptor. The F rster distances for AO-NB, EB-NB and RuBD-NB donor-acceptor pairs were 42.3, 52.3, and $30.6{\;}{\AA}$, respectively. All three donors showed dramatic decreases in fluorescence intensities and more rapid intensity decays with increasing NB concentrations. The intensity decays of AO and EB in the presence of varying concentrations of NB were satisfactorily described by the one-dimensional FRET model without diffusion (Blumen and Manz, 1979). In the case of the long-lifetime donor RuBD, the experimental phase and modulation somewhat deviated from the recovered values computed from this model. The recovered NB concentrations and FRET efficiencies from the model were slightly larger than the expected values, however, the recovered and expected values did not show a significant difference. Thus, it is suggested that the lifetime of RuBD is too short to measure diffusive processes in calf thymus DNA.

Background: Self-leadership, an action strategy that can maximize individual capabilities, can affect the organizational commitment of dental hygienists and ultimately improve the quality of medical services. This study aims to demonstrate the need for self-leadership and organizational commitment for dental hygienists and develop measures to improve the quality of medical services. Methods: An online survey of dental hygienists working at dental hospitals and clinics in Seoul and Gyeonggi province, Republic of Korea was conducted from March 28 to May 1, 2022. A total of 341 questionnaires were returned and analyzed. The measurement tools were modified and supplemented based on the theories and models developed by Manz for self-leadership, Mowday for organizational commitment, and Cronin and Taylor for medical services. Descriptive statistics, independent t-tests, ANOVA, simple regression, and multiple regression analyses were performed using SPSS 25.0. Results: In leadership education, self-leadership is based on participation experience, the number of participants, and when and where it is received. Organizational commitment comes from participation experience, and the quality of medical services has been found to affect participation experience and location. Self-leadership had an effect on the quality of medical services (β=0.497, t=10.551, p<0.001; β=0.599, t=13.783, p<0.001; β=0.353, t=7.601, p<0.001) and organizational commitment was found to have a mediating effect. Conclusion: Dental hygienists' self-leadership has a positive effect on the quality of medical services through the formation of appropriate interrelationships within the organization. Therefore, self-leadership programs should be developed, participated in, and promoted to improve the self-leadership of dental hygienists. Moreover, hospitals should improve their environment to provide and improve self-leadership education.
