The purpose of this study was to determine factors affecting the suicidal ideation in spouse caregivers of the elderly with dementia Living in the Community. The data were collected from 160 spouses of elderly people with dementia who use dementia support centers and long-term care service in seoul. Data were collected with structured questionnaires to investigate the general characteristics and suicidal ideation-related factors, and analyzed using t-test, ANOVA, Pearson's correlation coefficient, Multiple regression analysis with SPSS win version 24.0 program. The significant factors affecting suicidal ideation were entrapment(${\beta}=.452$), SDAP(${\beta}=.273$), coping strategies(${\beta}=-.199$), it were explained 55.7%(F=19.199, p<.001). Therefore, counseling and education should be provided to help reduce the entrapment and enhance coping strategy with the dementia condition of the elderly with dementia. Measures also need to be made to improve the accessibility of a spouse with dementia that are left neglected.

The purpose of this study is to figure out family member's perceptions of side rail use in geriatric hospital by Cavanagh's content analysis with in-depth interview. This finding of the study suggests that the six themes of these perceptions are precautionary safety supervision, movement convenience, ritualistic nursing, physical restraint, danger of wounds, and alternative methods in an older person ward, and that the cause of recognized perceptions is not based on actual events, but rather on relatives' perceived protective value. With the transition of medical industry environment, there is a significant emphasis on efficacy and effectiveness of practice, risk management and evidence-based practice. However, the issue of side rail use and physical restraints remains unsolved in care of older people. Nurses claim the necessity of regimented protocol and clarification from professional organization regarding the side rail use.

The MR ratios and the exchange biasing field and interlayer coupling field were investigated in $Ni_{91}Fe_{19}/Co_{90}Fe_{10}/Cu/Co_{90}Fe_{10}/NiO$ spin-valve sandwiches grown on antiferromagnetic NiO films as a function of the NiO thickness, the thickness of Cu and pinning layer $Co_{90}Fe_{10}$. The spin-valve sandwiches were deposited on the Corning glass 7059 by means of the 3-gun dc and 1-gun rf magnetron sputtering at a 5 mtorrpartial Ar pressure and room temperature. The deposition field was 50 Oe. The MR curve was measured by the four-terminal method with applied magnetic soft bilayer [NiFe/CoFe] (90$\AA$) decreased dramatically to less than 10 Oe when the NiFe/CoFe bilayer used an NiFe bilayer thicker that 20$\AA$. So NiFe layer improved the softmagnetic properties in the NiFe/CoFe bilayer. The GMR ratio and the magnetic field sensitivity of the spin-valve film $Ni_{91}Fe_{19}(40{\AA})/Co_{90}Fe_{10}(50{\AA}) /Cu(30{\AA})/Co_{90}Fe_{10}(35{\AA})/NiO(800{\AA})$ was 6.3% and about 0.5 (%/Oe), respectively. The MR ratio had 5.3% below an annealing temperature of 20$0^{\circ}C$ which slowly decreased to 3% above 30$0^{\circ}C$. The large blocking temperature of the spin-valve film was taken (as being) due to the good stability of the NiO films. Thus, the spin-valve films with a free NiFe/CoFe layer clearly had a high large GMR output and showed a effective magnetic field sensitivity for a suitable spin-valve head material.

Purpose: This study was designed to examine the relationships among daily hassles, social support, entrapment and mental health status in relation to gender in university students. Methods: Data were collected via a self- administered questionnaire from 118 male and 98 female college students in Kangwon province. Data were analyzed using SPSS/WIN 18.0 program for descriptive statistics, t-test, ANOVA, Pearson correlation, and stepwise multiple regression. Results: There were significant differences in daily hassles, entrapment and depression between male and female group. Also, there were significant relationship between entrapment and mental health status (i.e. depression, anxiety, hostility, somatization) in both groups. In male students, internal entrapment was the significant predictor of depression and anxiety, and external entrapment was the significant predictor of hostility and somatization whereas, in female students external entrapment was the significant predictor of depression, and internal entrapment was the significant predictor of anxiety, hostility and somatization. Conclusion: These results suggest that entrapment is an important factor for psychological maladaptation due to stressful life events. Therefore, strategies that reduce perception of entrapment according to gender should be developed for psychological adaptation.

Purpose: The purpose of this study was to examine the factors influencing the entrapment of primary caregivers of cancer patients. Methods: From 6 general hospitals, 146 primary caregivers of cancer patients who were receiving home healthcare nursing service were selected for the study. Regarding data collection, structured questionnaires were distributed to the caregivers for data collection. T-test, ANOVA and hierarchical regression were used for data analysis. Results: The significantly influential factors on their entrapment were caregiving time, taking turms to look after the patient, disease duration, home healthcare nursing period, quality of relationship, perceived health status, and social support. And the explanatory power was 55.1% Conclusion: To reduce primary caregivers' entrapment, it is necessary to perform comprehensive and continuous nursing intervention, and to develop a standardized home healthcare nursing intervention program, and to come up with a system for using resources available in local communities.

The critical currents I$_c$ of the YBCO grain boundaries of 90-degree [100] symmetric tilt showed a hysteretic behavior depending on how the external magnetic fields were applied. Near 77K for fields less than ${\sim}$1 T, the field-cooled I$_c$ of grain boundaries was larger than the zero-field-cooled I$_c$. This result is consistent with the model in which the grain-boundary vortices can be pinned by neighboring Abrikosov vortices in the nearby grains.

The solution properties of sodium n-dodecyl sulfate, as an anionic surfactant in the presence of a cationic watersoluble 5, 10, 15, 20-tetrakis (N-methylpyridinium-4-yl) porphyrin (TMPyP) has been comprehensively studied by means of conductometry, UV-vis and resonance light scattering (RLS) spectroscopies. The results represent the decreasing of critical micelle concentration of SDS solution due to increasing of TMPyP concentration. The stabilization of SDS micelle is due to neutralization of negative charge at the micelle surface. The presence of three different species of TMPyP in SDS solution has been unequivocally demonstrated: free porphyrin monomers, porphyrin monomers or aggregates bound to the micelles, and nonmicellar porphyrin/surfactant aggregates. Our results show SDS induced an aggregation in TMPyP. In fact two kinds of J-aggregations were observed: one of them for porphyrin monomers or aggregates bound to the micelles and the other for nonmicellar porphyrin/surfactant aggregates. However, the results represent the electrostatic interaction of TMPyP with SDS anion below the cmc.

Purpose: The aim of this study was to identify the status of psychological health among boys in high school and to examine the mediating effects of social support on the relationship between anger and entrapment on psychological health. Methods: The participants in this study were 193 high school boys from Jeju. Measurements included state-trait anger expression inventory, entrapment scale, student social support scale, and questionnaires to assess mental and physical health. Data were analyzed using independent t-test, one-way ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficient, simple and multiple regression techniques with the SPSS 21.0. Mediation analysis was performed with the Baron and Kenny's method, and Sobel test. Results: Mean scores for anger experience, entrapment, social support, and psychological health were $29.81{\pm}7.34$, $34.09{\pm}16.33$, $45.75{\pm}7.02$, $22.51{\pm}9.91$, respectively. There was a significant correlation between anger experience and psychological health. Entrapment was significantly correlated with psychological health. Social support showed partial mediating effects in the relationship between anger experience and psychological health (Sobel test: Z=54.18. p<.001). Social support showed partial mediating effects in the relationship between entrapment and psychological health (Sobel test: Z=2.24. p=.025). Conclusion: The results indicate a need to develop social support programs for boys in high school.
