This research is to study the interaction of multiculture parents in law between. daughter in law. We approached hermeneutical grounded theory and six of multiculture family's parent's in law participated this research. Data were collected by the depth interview and various written records and we could construct 9 hermeutical theme by analyzing and categorizing 83 meaning units, 22 categories. We descripted the process of acculturation between parent's in law and daughter in law. The result as follows : ① sticking self dimensions → ② strategic acceptomce → ③ making shade of co-existence → ④ self dismantling and reconstruction. Finally we proposed the 「joint program of parent's in law and daughter in law for reinforcing culture unpetence」.

This study applied hermeneutic grounded theory suggested by Rennie to understand general meaning of adoption decision process of 7 non-married mothers. At the end of the analysis, 191 meaning units, 46 subcategories, and 11 hermeneutic categories were constructed. The core category that threads throughout the adoption decision process was represented as "living with a scar left by the duality of motherhood; repudiating and embracing." The adoption decision process emerged as recognition of pregnancy, avoidance of reality, searching for adoption, escalation of confusion, determination and rationalization or forfeiture. Based upon our research, we suggested that the adoption decision process of non-married mother was another way of practicing motherhood, and we proposed that we need to develop a psycho-social support program to improve the lives of non-married mothers.

This research is to study the psychological, emotional, physical pains of the spouses of gambling addicts and the recovery process from the suffering. From this, we expect to propose a supportive program to help the recovery. Nine of the spouses of gambling addicts joined this research and the hermeneutical grounded theory methodology was applied to interpret it. Data were collected by the depth interview and various written records and they were analyzed by Rennie(2007)'s methodology. We could construct 20 categories by analyzing and categorizing meaningful units of the data. The core theme of the recovery experience was presented as "Stopping rolling the Sysyphus's boulder, and returning to the routine peace." Based upon the research outcomes, we suggested a supportive program considering male and female differences and a way to improve the accessibility to the therapy system for the spouses of gambling addicts and the need for a meaning therapy.

This study was conducted to explore initial motherhood experience of non-married mothers who decided to raise their babies. We applied Rennie's hermeneutic grounded theory for this study in which 7 non-married mothers participated. 9 hermeneutic categories which are 'decision to give birth', 'feeling of hitting bottom', 'ambivalence toward a life in stomach', 'realization of motherhood', 'motherhood anxiety', 'the bridle of social tag', 'hope of motherhood', 'encounter with new self' and 'visage of weary life' were constructed based on 145 meaning units, 34 subordinate categories. The core category that integrates motherhood experiences of participants was postulated as living with two conflicting visages of motherhood which are a cure and a poison at the same time. Motherhood experience processes were emerged in five stages which are decision to give birth, psychological frustration, realization of motherhood, confusion, and hope and discouragement of motherhood. Three types of motherhood experience were analyzed in the study which are adaptative, conflictive, and resistant. Based on the result of the study, the motherhood experience of non-married mother who decided to raise their babies are the process of emergence of new identity called mother. The non-married mothers formed their motherhood identities as they internalize socioculturally granted motherhood ideology. Moreover, the gap between socially oriented motherhood and realistic role of motherhood led to confusion. Based on this study, we suggest intervention plans to the field of social welfare practice that will support initial motherhood of non-married mothers who decided to keep their babies.

Two-element plate concept is incorporated into the buckling problem in order to simplify the nonlinear distribution of stress through the thickness of plate. Finite element formulations and programs based upon the Reissner functional and the modified Reissner functional using two-element plate concept are developed for buckling analysis of plates under axial compression. The two programs have been applied to obtain the linear elastic buckling behavior of axially compressed flat plates. Excellent agreement of linear elastic-solution results with exact or approximate solutions of other authors for the same boundary conditions proves the validity of the finite element method using two-element plate theory.

We suggest a method which solves the planar, two vehicle collision reconstruction problem. The method based on the Principle of impulse and momentum determines the pre-impact velocity components from Post-impact velocity components, vehicle Physical data and collision geometry. A novel feature is that although the impact coefficients such as the restitution coefficient and the impulse ratio are unknown, the method can estimate automatically the coefficients and calculate the pre-impact velocity components. This reverse calculation is important for vehicle accident reconstruction, since the pre-impact velocities are unknown and Post-impact Phase is the starting Point in a usual collision analysis. However. an inverse solution is not always Possible with the analytical rigid-body impact model. Mathematically, one does not exist under the common velocity condition. On the other hand, our method has a capability of reverse calculation under the condition if the absorbed energy during the collision process can be estimated using the crush profile. To validate the developed collision reconstruction a1gorithm, we use car-to-car collision test results. The analysis and experimental results agree well in the impact coefficients and the Pre-impact velocity components.

The ultimate bearing capacity of surface foundations on a sand layer overlying clay has been theoretically investigated. First, a review of previous studies on the bearing capacity problems for this type of foundation was performed and a discussion was presented concerning the practical application. Second, the kinematic approach of limit analysis was used to calculate the upper bound of the true ultimate bearing capacity. The kinematic solutions are upper bounds and their accuracy depends primarily on the nature of the assumed failure mechanism. This approach makes it convenient to create design charts, and it is possible to trace the influence of parameters. Third, the commercial finite element program ABAQUS was applied to obtain the ultimate bearing capacity based on the elasto-plastic theory. Results obtained from the kinematic approach were compared with those from the program ABAQUS and the limit equilibrium equations proposed by Yamaguchi, Meyerhof and Okamura et al. Finally, the validities of the results from the kinematic approach, the results from the program ABAQUS and the limit equilibrium equations were examined.

현장상황에 대한 불충분한 자료와 파괴 메커니즘에 대한 불완전한 이해로 인해 발생하는 가변성(variability)과 불확실성(uncertainty)은 암반사면공학뿐만 아니라 지반공학에서 흔히 접하게 되는 문제점이다. 특히 암반사면공학에서는 이러한 가변성과 불확실성이 불연속면의 방향 및 기하학적 특성, 그리고 실내실험 결과의 분산으로 나타난다. 그러나 안전율(factor of safety)의 개념을 기초로 하는 전통적인 결정론적 해석방법(deterministic analysis)은 이러한 분산을 고려하지 않은 채 단일 대표 값만을 이용하여 구조물의 안정성을 판단하여 왔다. 확률론적 해석방법(probabilistic analysis)은 이러한 가변성과 불확실성을 효과적으로 정량화하여 해석에 이용할 수 있는 방법 중의 하나로 제안되었다. 이러한 해석방법은 불연속면의 기하학적 특성과 강도 특성을 확률변수(random variable)로 취급하여 신뢰성이론(reliability theory)과 확률이론(probability theory)을 근거로 분석하였으며 이를 기초로 하여 Monte Carlo Simulation과 같은 해석법을 이용, 구조물의 붕괴가능성을 확률로 표현하였다. 확률론적 해석 방법은 기존의 안전율을 대체하여 구조물의 안정성을 붕괴확률(probability of failure)로 제안하였으며 이 붕괴확률은 안전율의 확률분포함수 (probability density function)에서 안전율이 1보다 작을 가능성을 확률로 나타낸 수치이다. 본 논문에서는 확률론적 해석방법을 이용하여 불연속면 특성들의 확률특성을 고찰하였으며 이를 기초로 하여 암반사면의 안정성 해석에 응용했다.
