  • The structural phase transition of $Cs_2MnCl_4{\cdot}2H_2O$ single crystals was investigated by determining the $^{133}Cs$ spin-lattice relaxation time $T_1$. The number of resonance lines in the $^{133}Cs$ spectrum changes from seven to one near 375 K, which means that above 375 K the Cs sites are symmetric. Further, the $T_1$ of the $^{133}Cs$ nucleus undergoes a significant change near 375 K, which coincides with the change in the splitting of the $^{133}Cs$ resonance lines. The change in $T_1$ near $T_C$ is related to the loss of $H_2O$, and means that the forms of the octahedra of water molecules surrounding $Cs^+$ are disrupted.

  • The purpose of this study was to investigate the variables on employees' retirement expectations divided into imposed frustration, new beginning, transition to rest, and continuing. Independent variables were individual(gender, age, occupation, income, education, and health condition), psychological(self-esteem, locus of control, attitude of leisure, and attitude of family), and job-related variables(job attitude, job satisfaction, and job stability). In order to achieve this purpose, a survey was conducted with 515 employees from Daegu and Kyungpook. Retirement expectations were measured with questionnaire based on several studies. The data analyzed by frequency, percentage, mean, factor analysis, Cronbach's $\alpha$, correlation, and multiple regression. The major findings were as follows. First, imposed frustration was affected by income, self-esteem, locus of control, job satisfaction, job attitude, and job stability. Second, new beginning was affected by self-esteem, locus of control, attitude toward leisure and family, and job stability. Individual variables were not statistically significant predictors of new beginning. Third, transition to rest was affected by locus of control, attitude toward family, job satisfaction, job attitude, and job stability. Individual variables were not statistically significant predictors of transition to rest. Finally, continuing was affected by age, education, job satisfaction. Psychological variables were not statistically significant predictors of continuing.

  • From the 1920s to 1945, East Asia experienced radical social change with the introduction of new fashion styles, and new ways of thinking, from the West. The emergence of a new generation of "new women" educated in modern schools was part of this phenomenon, and functioned as a trend-setting influence in East Asian society. In schools, education in dressmaking, sewing, and home economics were important parts of female education. Adopting a new fashion style is, by necessity, accompanied by the new technology of dressmaking. Given that ready-made clothing was not generally available, dressmaking education also served to introduce a new material culture. In Korea and Taiwan under Japanese colonization, the greater part of school curricula and textbooks mirrored those in Japan, which enabled these countries to develop and adopt transnational styles as well as local styles. This research explores the transition of women's fashion in East Asia in modern and colonial conditions from the 1920s to the 1940s by analysing curricula and textbooks on dressmaking in comparison with the prevailing styles in each region. This is expected to suggest the impact of modernity in East Asia and the transnational styles of fashion in colonial Korea and Taiwan, as well as Japan, developed within the local culture. Colonial conditions are also discussed in terms of their impact and limitations in the transition of styles.

  • This study investigated highschool students' brain waves on functional tasks such as a transition(F task) from equation to graph and the other transition(G task) vice versa. A total of 39 students participated in the study who attended a high school located in Gyunggi province. These students were divided into two groups, HMA and LMA by MASS test revised by Ko, & Yi (2012). The functional tasks for the stroop task to measure EEG were provided from a previous study, Seok(2015). The results indicated two groups on G tasks showed deeper and wider brain waves which demonstrated G tasks were more difficult than F tasks. However, HMA group had an effect of the non-psychological program which had given more chances on G tasks rather than F tasks within Students' Zone of Proximal Development. Also, HMA group's brain waves had more ranges in amplitude and width of waves. These results imply that the characteristics of students' brain waves with math anxiety are consistent to the previous studies.

  • New silicon-monosubstituted (${\eta}^4$-2,3,4,5-tetraphenyl-1-silacyclopentadiene)transi tion metal complexes are described. The new (silole-transition metal complex)Fe$(CO)_3$ was obtained from the reaction of silole-tansition metal complex and Fe$(CO)_5$. We have determined the crystal structure of (${\eta}^4$-exo-cyclopentadienyldicarbonyliron-endo-1-meth yl-2,3,4,5-tetraphenyl-1-silacyclopentadienyl)tric arbonyliron by using graphitemonochromated Mo-$K_{\alpha}radiation. The compound was crystallized in the monoclinic space group $P2_1$/c with a = 8.925(1), b = 18.689(3), c = 19.930(3) ${\AA}$, and ${\beta}$ = 102.02$(1)^{\circ}$. The iron moiety CpFe$(CO)_2$ on silicon is in an axal position. The (silole-transition metal complex) Fe$(CO)_3$ was also prepared through the reaction of (${\eta}^4$-1-chloro-2,3,4,5-tetraphenylsilacyclopentadiene) Fe$(CO)_3$ and metal complex nucleophile. The structure configuration was studied by conventional spectroscopy.

  • Purpose: The purpose of this study was to explain the role transition process to nurse case managers (NCMs) for Medical-aid beneficiaries in Korea. Methods: Fourteen NCMs were interviewed regarding their experiences of becoming proficient in the new role of case manger. Data were analyzed through the application of grounded theory. Results: 'Taking root in a barren land' was the core category explaining the role transition process of NCMs. They engaged in four stages: launching, trial and error, proficiency, and wait-and-see stages. NCMs showed not only fear but also passion for case management practice. Despite their passion and effort, NCMs went through a period of trial and error. After becoming skilled, NCMs went through a stage of wait-and-see often because of job insecurity related to temporary position or few opportunities for promotion. Factors influencing NCMs' role transition process included their understanding of client characteristics, belief in case management, and support from their colleagues and families. Conclusion: NCMs experience many challenges in the process of becoming proficient NCMs. To help with their role transition, there is a need for education programs, preceptorship programs, research on their roles and functions, and regulation for securing NCMs' employment and career stability.

  • Purpose: This study was done to identify differences in the life transition process of parents caring for children with autism according to parents' socio-demographic characteristics. Methods: Participants were 194 parents caring for children with autism. Data were collected from December 2013 to February 2014 through self-report questionnaires, and analyzed using descriptive statistics, t-test, ANOVA with SPSS/WIN 20.0. Results: Mean scores for despairing or accepting phases were higher than those for denying or wandering phases in the life transition process. According to parents' gender, educational level, and job, there were some significant differences in the denying and wandering phases. Differences in denying phase by education (p=.033), job (p=.004) were significant. Respondents with higher educational level, and having a job showed a lower level of denying than other respondents. Wandering phase differed significantly by gender (p=.009) and job (p=.001). Mothers and those who did not have a job showed a higher level of wandering than fathers and those who had a job. However, there was no difference in the despairing or accepting phases. Conclusion: The life transition phase of parents with autistic children needs to be assessed to provide differentiated and intensive support program and help them move to the accepting phase.

  • 화석연료의 고갈과 국제 유가의 폭등, 기후온난화와 빈번한 환경 재난은 자원 및 환경 담론과 정책의 강화를 요청했으며, 이에 따라 지속가능한 발전의 개념이나 탄소 규제 전략에 바탕을 둔 정책들이 추진되어 왔다. 그러나 이러한 기존 개념이나 전략들은 신자유주의화 과정에 포섭되면서, 실효성이 있는 성과를 얻지 못했다. 이러한 점에서 새로운 전략적 규범적 개념으로 에너지 전환과 더불어 에너지 자립의 개념이 제시된다. 대구시는 비교적 일찍 에너지 문제에 관심을 가지고 솔라시티 정책을 추진해 왔지만, 거시적 배경에 편승하여 도시 에너지 문제를 제대로 대응하지 못했다. 이러한 점에서 이 논문은 대구시의 에너지 문제 실태와 정책의 의의와 한계를 살펴보고, 도시 에너지 전환과 자립을 위한 4가지 원칙, 즉 화석에너지 및 핵에너지에서 재생가능 에너지로의 전환, 공급주도형에서 수요관리 중심 정책으로의 전환, 중앙집중형에서 지역분산형 에너지 시스템으로의 전환, 그리고 시장의존적 관리에서 시민 참여적 에너지 거버넌스로의 전환 등을 제안하면서 이에 바탕을 둔 구체적 방안들을 제시하고 있다.

  • Spin Hamiltonian for the paramagnetic center with a three-fold symmetry and high spin ($S{\geq}2$) multiplicity should contain the fourth order zero-field splitting (ZFS) terms. Electron magnetic resonance transition lines of the center with S = 5/2 are expected to split in a pair when the magnetic field is applied off the principal axes of ZFS, while they are superimposed when the magnetic field is applied parallel to the principal axes of ZFS. In this study we report that the transition lines of $Mn^{2+}$ centers at the three-fold symmetric sites in $LiNbO_3$, chemically equivalent but physically different, split in two due to the nonzero fourth order ZFS term.
