BiPbSrCaCuO 계 초전도체에서 관측되는 자기부양효과에 대하여 연구를 수행하였다. BiPbSrCaCuO 계 초전도체에 산화은을 첨가한 시료와 첨가하지 않은 시료의 자기적 특성을 측정하여 자기부양효과의 메카니즘에 대하여 고찰하였다. toroidal자석에서 관측되는 자기부양 효과는 자석의 중심부분에서만 발생하며, 자석의 ring 부분에서는 관측되지 않았다. 이 결과는 본 연구의 자기 부양효과의 발생에는 자석의 형상 및 자속의 분포 형태와 밀접한 관련이 있음을 의미한다.

BiPbSrCaCuO계 초전도 소결체에 산화은을 첨가하여 자기 부양 효과를 나타나는 시료의 제작 조건을 조사하였다. 2%의 산화은이 첨가된 시편에서 자기 부양 효과가 가장 효과적으로 관측되었다. toroidal자석에서 관측되는 자기 부양 효과는 자석의 중심부분에서만 발생하며, 자석의 ring부분에서는 관측되지 않았다. 이 결과는 본 연구의 자기 부양 효과의 발생에는 자석의 형상 및 자속의 분포 형태와 밀접한 관련성이 있음을 의미한다. 자기 부양 효과에 관한 측정 결과로부터 자속 밀도가 극소가 되는 장소에 초전도체가 놓이게 되면 초전도체는 반자성효과로 인하여 초전도체의 상하로부터 작용하는 자기력을 받게 된다. 또한 산화은을 첨가하지 않은 BiPbSrCaCuO계 초전도체와 2%의 산화은이 첨가된 시편의 자기부양 효과를 조사한 결과 pinning center의 역할이 중요함을 알 수 있다.

The purpose of this study is to provide a basic data for reducing care-giving stress of family members of the elderly with mild dementia by determining the relationship between the behavioral and psychological symptoms of the elderly with dementia and their family members' care-giving stress and self-efficacy. The descriptive statistics, t-test, and ANOVA were used for analysis in order to investigate the relationship. The behavioral and psychological symptoms of the elderly with mild dementia and their family members' care-giving stress had a positive correlation (r=.655, p<.001), and as their family members' care-giving stress and the members' self-efficacy had a negative correlation (r=-.334, p<.001). Based on the result of this study, it is necessary to reduce the care-giving stress of family members of the elderly with mild dementia and improve the self-efficacy of family members by developing proper measures to cope with the behavioral and psychological symptoms of the elderly with mild dementia.

The purpose of the current research is to reconstruct the process in which changes in elderly support take place from the perspective of the elderly in rural areas. Six elderly couples were interviewed three times with the use of Schütze's 'autobiographical-narrative interview'. The entire interviews consisted of 17 sessions. Interviewed data was analyzed, following the method of Schütze's 'autobiographical-narrative interview analysis'. Research findings were as follows: Elderly support as experienced by the current elderly couples is mainly 'family support', which turned out to be 'dual structural shift' in the process of modernization. That is, there has been an 'internal structural shift' from 'family support on intergenerational, mutual support dimension' to 'family support on intragenerational self-support dimension' on the one hand. An 'external structural shift' has been noticed that realizes the 'socialization of family support' on the other hand. Additionally, a 'discrepancy' was captured between support norm and support behavior as occurred in the process of 'dual structural shift'. Perception on the 'dual structural shift' has proven 'ambivalent'. On the basis of these results, a critical discussion of modernization theory ensued, along with some implications for practice.

본 연구에서는 일차적인 부양자로서의 역할을 담당하고 있는 며느리들을 중심으로 시부모를 부양하면서 느끼는 스트레스를 완하시킬수 있는 자원에는 어떤 것들이 이는지를 살펴봄으로써 효과적인 시부모 부양방안을 규명하는데 그 목적이 있다. 767명의 며느리들을 대상으로 자료를 수집하여 회귀분석해 본 결과 자기통제력.부모부양태도와 같은 개인적요인, 부양의 호혜성.관계의 질과 같은 관계적 요인 및 비공식적 지원망의 성원들로부터의 지원과 같은 가족사회적 요인등이 부양스트레스 인지를 낮추는 것으로 나타나 이들요인들이 시부모를 부양하면서 부담 내지 스트레스를 느끼는 며느리들에게 주요한 부양자원이 된다고 할 수 있다. 이를 감안해 볼 때, 며느리의 부양 부담 및 스트레스를 낮출수 있는 다양한 자원에 초점을 둔 지역사회 단위의 교육 및 상담사업의 필요가 절실하다고 하겠다.

본 연구는 노부모부양가족의 어려움과 요구에 적합한 프로그램을 개발하여 노부모를 부양하는 성인자녀를 실제적으로 도와주고 그들의 부양부담감을 감소시키고자 하는 데에 목적이 있다. 이러한 목적을 위해서 일차적으로 우리나라 노부모 부양가족의 요구가 고려된 실험적 노부모 부양가족 프로그램을 구상하였다. 구상된 프로그램으로 노부모가 한분이라도 생존해 계신 여덟명의 교육대상을 소규모 집단으로 모집하여 시범교육을 실시하였다. 실시과정에서 파악되는 문제점과 개선점을 검토하고 사전 검사후 사후 검사를 2회 실시하여 프로 그램의 효과를 검증평가하였다. 그 결과 본 프로그램의 참여가 프로그램의 목적과 관련된 부양에 필요한 지식정보와 자기결단 및 통제력 수준을 향상시키고, 부양자로 하여금 보다 긍정적인 노부모 부양태도나 인식을 가지게 한 것으로 나타나 프로그램의 효과성을 입증해 주었다.

The purpose of this study was to investigate the influences of characteristics of the long-term care elderly and caregivers on caregivers' stress. The data of this study were collected from 105 long-term care elderly caregivers with 3 grade in Pusan, Daegu, and Gyung-buk area. The results showed that each stress of caregivers was influenced by diverse characteristics in various ways. Time-dependent stress of caregivers was influenced by elderly dependency and caregivers' health. Self-development stress of caregivers was influenced by elderly dependency, caregivers' health, caregivers' age, and relationship quality. Physical stress of caregivers was influenced by elderly dependency and caregivers' health. Social stress of caregivers was influenced by elderly dependency, caregivers' health, and relationship quality. Emotional stress of caregivers was influenced by relationship quality between the elderly and caregivers. These results indicated that the caregivers' stress was influenced not only physical characteristics of the elderly and the caregivers but also relational characteristics.

In this paper, the requirements of passive levitation for nonmagnetic body in magnetic fluid are investigated. The passive levitation system includes the electromagnetic system composed of two hollow solenoids, the magnetic fluid and the nonmagnetic body made of aluminum. The hollow solenoids generate nonuniform magnetic fields, leading to the gradient of the magnetic field in magnetic fluid. Hence, the resultant magnetic body force in magnetic fluid is used to levitate the nonmagnetic body in the opposite direction of the gravitation. The levitation conditions according to applied current and the mass of the nonmagnetic body are obtained analytically.

The purpose of this study is to examine the effects of care-giving stress of dementia elderly on the caregiver's suicidal ideation. In addition, mediating effect of self-efficacy was examined. In order to accomplish these purposes, a total of 336 who are caregivers of dementia elderly using self-report questionnaires. In this study, 325 elderly patients were used for final analysis. Date were analyzed by frequency and descriptive analysis, regression model analysis with SPSS 22.0. The analysis result of dementia elderly caregiver's symptoms showed that prevalence of suicidal ideation were 32.6%. Regression analysis was conducted under the control of dementia elderly's disease period, ratings, general characteristics and age, sex, educational background, occupation status, health status, living standard level of caregivers who were the subject of the survey. As a result, it was confirmed that the care giving stress had a statistically significant effect on suicidal ideation. Also, the self-efficacy of caregivers was found to partial mediate the relationship between care-giving stress and suicidal ideation(***p<.001). Based on this result, I suggested the various policies and the necessity of social welfare intervention to restore the mental health of caregivers of the elderly with dementia.

The main purpose of this research is to investigate the effect of Korean adults' perception of parent-child relation on their self-efficacy, child rearing practices, elderly parent care practices, and happiness. In this study the parent-child relation is a relationship between the adults' parents and the adults. The participants in the study were adults (2,632; male=1,275, female=1,357) with children in primary, secondary, and/or university, with an average age of 45.44-years-old (male=46.96-years-old, female=44.10-years-old). The results showed a direct influence of the adults' perception of parent-child relation on their self-efficacy and their child rearing practices, and an indirect influence on their happiness. This indicates that a more positive adult's perception of parent-child relation leads to higher self-efficacy and greater devotion to their child rearing practices. And furthermore, an elevated self-efficacy enhanced their happiness. Gender differences were found for the influence of adults' perception of parent-child relation on elderly parent care practices. For Korean male adults, a more positive perception of parent-child relation lead to a more active participation in elderly parent care practices. However, for Korean female adults no direct influence was found. Based on these results, a discussion of the influence of adults' perception of parent-child relation on the adults' psychological characteristics and family-members relationships is provided.
