Purpose: The purpose of the study was to assess married couples' attitude toward family-birth according to the range of spouse's participation in family-birth. Method: Data were obtained by the 54 couples who used to visited in order to participate on family-birth at two teritary women's hospital in G-city. Result: There was a significant difference in pregnant woman's attitude : the status of having a job(Z=-2.01, p=.044) & type of nuclear family(Z=-2.17, p=.029), planned pregnance(Z=-2.54, p=.011). The spouse who partly participated in the process of family-birth showed higher(t=2.30, p=.030) compared to the spouse who participated in the whole process of family-birth. Conclusion: The results of the study suggest that hospitals and women's hospitals should support pregnant woman's social work and encourage spouse who partly participation and develop education programs.

This paper is concerned with the convergence of double trigonometric series and Fourier series. Since the beginning of the 20th century, many authors have studied on those series. Also, Ferenc $M{\acute{o}}ricz$ has studied the convergence of double trigonometric series and double Fourier series so far. We consider $L^p(T^2)$-convergence results focused on the Ferenc $M{\acute{o}}ricz^{\prime}s$ studies from the second half of the 20th century up to now. In section 2, we reintroduce some of Ferenc $M{\acute{o}}ricz^{\prime}s$ remarkable theorems. Also we investigate his several important results. In conclusion, we investigate his research trends and the simple minor genealogy from J. B. Joseph Fourier to Ferenc $M{\acute{o}}ricz$. In addition, we present the research minor lineage of his study on $L^p(T^2)$-convergence.

The purpose of this descriptive research was to investigate importance awareness on peripheral intravenous infusion, and to identify the factors influencing on importance awareness among 128 children's hospital nurses. The collected data were analyzed with descriptive statistics, T-test, ANOVA, Pearson's correlation analysis and Hierarchical multiple regression using SPSS 21.0. Importance awareness on peripheral intravenous infusion of children's hospital nurses was the lowest in education, and the highest in hand hygiene. There were significant differences in subdomains of peripheral intravenous infusion according to marriage state, working department, position and final education(p<.001~.046), and there were positive correlations between education and importance awareness of peripheral intravenous infusion(p<.001). And factors affecting importance awareness were education(${\beta}=.446$) and working department(${\beta}=.247$), and explannation rate was 31.0%(p<.001). These results could be used as basic data of educational program on peripheral intravenous infusion for children's hospital nurses after repeated study.

Many iterative algorithms like that Picard, Mann, Ishikawa and S-iteration are very useful to elucidate the fixed point problems of a nonlinear operators in various topological spaces. The recent trend for elucidate the fixed point via inertial iterative algorithm, in which next iterative depends on more than one previous terms. The purpose of the paper is to establish convergence theorems of new inertial Picard normal S-iteration algorithm for nonexpansive mapping in Hilbert spaces. The comparison of convergence of InerNSP and InerPNSP is done with InerSP (introduced by Phon-on et al. [25]) and MSP (introduced by Suparatulatorn et al. [27]) via numerical example.

A Convergence study was conducted to investigate the factors influencing the burnout in caregivers and to present a strategy for effective program development. The subjects of this study were 185 caregivers who had worked for 6 months in a G city Nursing facility and distributed the self-reported questionnaire in September 2015. Data were analyzed using t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson's correlation coefficient and Stepwise multiple regression analysis were performed. According to the results, the identified influencing factors were stress of personal role and daily work factors(${\beta}=.307$, p<.001), stress of relationship with supervisors(${\beta}=.186$, p<.021), confidence(${\beta}=.182$, p<.005), passive coping(${\beta}=.140$, p<.035) with burnout in caregivers. The explanatory power($R^2$) by 4 variables was 27.5%. Based on the results of this study, it would be necessary to develop an burnout reduction program that can reduce stress, increase self-confidence, and diversify coping strategies in order to reduce burnout of caregivers.

A Convergence study was attempted to identify the effects of stress on Suicidal ideation and mediating effects of depression in the relationship. The study were 166 elderly's over 65 years at G city and period was from August 29 to September 9, 2018. Data were analyzed PASW 18.0 program. As a result, stress had a significant effect on depression in stage 1, stress had a significant effect on suicide ideation in stage 2, stress and depression of parameter were significant predictors in stage 3. The explanatory power of the two variables was 24.3% in stress, 26.8% for stress accompanied with depression, and the partial mediating effect of depression on the effect of stress on suicide ideation. Based on this study, it can be used as a basic data for reducing suicide ideation of the elderly and study is needed to develop suicide prevention programs.

We fabricated the distributed feedback (DFB) InP/InGaAs/InP grating structures on InP (100) substrates by metal-organic chemical vapor deposition, and their structural properties were investigated by atomic force microscopy and scanning electron microscopy. Self-assembled InAs/InAlGaAs quantum dots (QDs) were grown on the InP/InGaAs/InP grating structures by molecular beam epitaxy, and their optical properties were compared with InAs/InAlGaAs QDs without grating structure. The duty of the grating structures was about 30%. The PL peak position of InAs/InAlGaAs QDs grown on the grating structure was 1605 nm, which was red-shifted by 18 nm from that of the InAs/InAlGaAs QDs without grating structure. This indicates that the formation of InAs/InAlGaAs QDs was affected by the existence of the DFB grating structures.

The purpose of this convergence study was to identify the effects of favorite music therapy on anxiety, fatigue, and vital signs of patients undergoing prostatectomy with spinal anesthesia. This study used a nonequivalent control group design. A sample of 45 patients was included. The experimental group was given music therapy during operation. The data were collected using a structured questionnaire and monitoring at 30 min before operation, at 20 min and 40min undergoing operation, and at arrival recovery room after operation. Data were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test, repeated measures ANOVA. The experimental group reported significantly lower anxiety and lower fatigue than the control group(p=.001; p=.020). However there were no significant differences in the systolic blood pressure, diastolic blood pressure and pulse rate between groups(p=.821; p=.473; p=.782). This findings indicate that the tailored favorite music therapy can be an effective nursing intervention for patient undergoing prostatectomy with spinal anesthesia to reduce anxiety and fatigue related to operation.

We analyze the convergence properties of Powell's UOBYQA method. A distinguished feature of the method is its use of two trust region radii. We first study the convergence of the method when the objective function is quadratic. We then prove that it is globally convergent for general objective functions when the second trust region radius p converges to zero. This gives a justification for the use of p as a stopping criterion. Finally, we show that a variant of this method is superlinearly convergent when the objective function is strictly convex at the solution.

This study was purposed to figure out current situation of part of 273 middle-school girls' dietary behavior and problems, then provide baseline data which helps to develop desirable eating behavior and life style. It appeared that suitable amount of eating(F=6.378, p=.002), degree of unbalanced diet(F=3.542, p=.030), Nutrients intake(F=6.780, p=.001), and life style(F=4.291, p=.015) differs between groups depending on student's subjective physical health status. It turned up that perceived physical health status is related to moderate amount of eating, degree of unbalanced diet, and Nutrients intake(p<0.05). As a results, in the period of adolescent which is a rapid growth period, there should be a systematic and endurable practice of right eating behavior, foods for formation of lifestyle, and convergence education in health area.
