The propose of this study was to develop the new pre-parent education program for couples in i=transition to parenthood. This program was consisted three process, total eight sessions. The first process(the basic process) has two sessions. This process was designed to understand the whole parenthood, and to cope the role strain in early parenting period. The second process has three sessions, designed to enrich the marital relationship before the baby was born. And the Third process(parent-child process) has three sessions, too. Especially in last sessions, parent can exercise infant caring, and adapt fetus to their family member.

High oxygen pressures appear an important tool in Solid State Chemistry. Two main routes can be developed: (i) the stabilization of thermally unstable oxides, used as precursors, in order to open the synthesis of new materials, (ii) the stabilization of the highest oxidation states of transition metals. This paper is essentially devoted to this second research axis. The methodology developed for preparing new oxides containing Fe(Ⅴ), Ir(Ⅵ), high spin Fe(Ⅳ) and Cu(Ⅲ) is described.

2,5-Di-(2'-hydroxyethoxy)-4'-nitrostilbene (3) was prepared and polycondensed with terephthaloyl chloride, adipoyl chloride, and sebacoyl chloride to yield novel T-type polyesters (4-6) containing the NLO-chromophores dioxynitrostilbenyl groups, which constituted parts of the polymer backbones. Polymers 4-6 are soluble in common organic solvents such as acetone and N,N-dimethylformamide. They showed thermal stability up to 260 oC in thermogravimetric analysis with glass-transition temperatures obtained from differential scanning calorimetry in the range 90-95 oC. The second harmonic generation (SHG) coefficients (d33) of poled polymer films at the 1064 nm fundamental wavelength were around 1.42 ´ 10-9 esu. The dipole alignment exhibited high thermal stability up to 5 oC higher than glass-transition temperature (Tg), and there was no SHG decay below 100 oC due to the partial main-chain character of polymer structure, which is acceptable for NLO device applications.

An aquifer thermal energy storage (ATES) model is simulated by FEFLOW according to the scenario of heat pump operation in two layered confining aquifer. The scenario is consisted of 4 steps: 90 days pumping (west well) and waste water injection (east well: 35 $^{\circ}C$), 90 day s stop, 90days pumping (east well) and waste water injection (west well: 5 $^{\circ}C$), and 95 days stop. The injection of the waste water is limited in the second layer and the first layer is aquitard. The temperature distribution at the surface shows low difference with reference temperature and opposit aspect with that of the second layer because the thermal transition through the first layer is very slow. Even though the simulated thermal transition in the aquifer system have a difference with real ATES system, optimal design and operate system can be developed with field tests and operational experience.

MgB$_2$samples have been prepared by a stoichiometry mixture of Mg and B inside stainless steel tubes(Commercial Stainless Steel Tube Enveloping Technique). XRD data show that there are no second phases like MgO. The transition temperature of specimens is 37.5 K with a sharp transition width of ΔTc within 1K. From magnetic hysteresis measurement, flux jump was shown up to 15K, which was higher than that of samples by other methods. We have concluded that the flux jump is mainly affected by impurities and second phases.

Optimal control gain for time-delay systems is made by an optimal control gain for delay-free systems multiplied by a state transition function for the delay time. The optimal control gain for delay-free systems is obtained by pushing two zeros of the PID controller closely to a larger pole of the second order plant. Thus the optimal tuning of PID controller for time-delay second order system is able to be obtained by calculation for the state transition function.

Our experimental research focuses on manipulating pinning deflects to alter the phase diagram of vortex matter, creating new vortex phases. Vortex matter offers a unique opportunity for creating and studying these novel phase transitions through precise control of thermal, pinning and elastic energies. The vortex melting transition in untwinned YB $a_2$C $u_3$ $O_{7-}$ $\delta$/ crystals is investigated in the presence of disorder induced by particle irradiation. We focus on the low disorder regime, where a glassy state and a lattice state can be realized in the same phase diagram. We follow the evolution of the first order vortex melting transition line into a continuous transition line as disorder is increased by irradiation. The transformation is marked by an upward shift in the lower critical point on the melting line. With columnar deflects induced by heavy ion irradiation, we find a second order Bose glass transition line separating the vortex liquid from a Bose glass below the lower critical point. Furthermore, we find an upper threshold of columnar defect concentration beyond which the lower critical point and the first order melting line disappear together. With point deflect clusters induced by proton irradiation, we find evidence for a continuous thermodynamic transition below the lower critical point..

This study examined the experiences and meanings of career transition becoming a counselor by examining the experiences of career transition process before two women became counselors through the narrative inquiry method. To do this, two counselors with career counseling qualifications and two or more career transition experiences were selected as research participants. The results are as follows. First, they had several career experiences without having the opportunity to think about their interests or aptitudes. Second, it was an experience that career transition adapts itself. Third, as they went through various occupations, they gradually went to the work and study they wanted. Fourth, They were satisfied with the profession of the counselor they had chosen, and they were inspecting themselves as a counselor. In this study, it is meaningful to accept the career transition as a part of life and to confirm the meaning of career transition experience as a counselor walking the path of counseling specialist.

Results: The results of this study could be summarized as follows. First, the reputation and interaction of the characteristics of franchise educational institution had significantly positive(+) effects on the educational transition. Second, all the sub - variables of educational contents such as job relevance, education method, and instructors' professionalism had positive(+) effects on the educational transition while the educational transition had positive effects on the organizational commitment, career commitment, and job commitment. Lastly, the organizational commitment and job commitment had positive(+) effects on the recommendation intention. Thus, the trainees with higher organizational commitment and job commitment in a franchise educational institution, showed higher intention to recommend the educational institution to others. Conclusions: The results of this study imply that the franchise educational institutions could increase the actual performance of education such as educational transition, commitment, and recommendation intention by increasing interactions within educational institutions and also designing effective educational contents, so that the trainees could highly perceive the educational transition of education.

Purpose: The purpose of this study was to identify factors that can affect transition shock in newly-graduated nurses. Methods: The first descriptive written survey was conducted on 450 graduate students from five nursing colleges. After their employment, the second survey was conducted on 316 participants who had responded to the first survey. A total of 158 respondents were used for the final analysis. Data were analyzed using an independent t-test, ANOVA, Tukey test, Pearson's correlation coefficient, and hierarchical multiple regression analysis with the SPSS Win 25.0 Program. Results: The average age of the participants was 24.25±4.47. Of the participants, 126 (79.8%) were satisfied that they had majored in nursing. The average score for transition shock was 2.61±0.55 points. Factors influencing the transition shock of newly-graduated nurses were the working department, working period, and working environment. The more positively the newly-graduated nurses perceived the nursing work environment, the less of a transition shock they experienced. Grade point average, clinical competence, confidence in performing core nursing skills, and nursing professionalism did not affect their transition shock. It could be confirmed that there is a gap between college nursing education and the clinical field. Conclusion: In order to reduce the transition shock of newly-graduated nurses, it is necessary to improve the nursing work environment and apply educational and emotional support strategies according to the characteristics of each work department and the period of work.
