본 연구는 이냐시오 성인의 성찰과 식별방법에 기초하여 우리사회의 자살, 자살시도자, 자살유가족에 대해 살펴본 내용이다. [이웃의 죽음]으로 정리된 내용은 어린 시절의 학대경험과 연결된 성인기 자살위험성 발현과 취약한 사회적 안전망 속에서 조금만 문제가 생겨도 쉽게 사각지대에 놓이게 되고 사회적 무관심과 고립 속에서 극단적 선택으로 사라져가는 이웃의 모습을 본 것이다. [유가족과의 만남]에서는 자살에 부여된 낙인으로 인해 감당하기 힘든 슬픔을 표현할 수도 없고 애도할 수도 없는 자살유가족의 상황과 고인의 죽음선택 이유를 계속해서 자신에게 귀인 시키며 스스로를 괴롭히며 살아가는 유가족의 모습을 본 것이다. 상담현장에서 이루어진 내적 성찰과 식별은 가톨릭 평신도들과의 공동체적 성찰과 식별과정을 거쳐 ‘이웃 생명에 대한 우선적 관심“이라는 실천적 주제로 이어졌다. 이와 함께 제시한 대안은 어려움에 처한 사람에게 귀 기울이는 ‘생명의 소리를 듣는 영성’, 가정에서부터 어린생명이 보호받을 수 있는 ‘생명을 키우는 영성’, 가난한 이웃과 자살유가족을 적극적으로 지원하는 ‘생명을 돌보는 영성’ 등 세 가지로 정리되었다. 이러한 방향이 앞으로 가톨릭 공동체가 가야 할 길이라고 보았다. This study explores the suicide phenomenon and suicide attempters and family survivors in South Korea that based on the reflections and spiritual discernments of St. Ignatius (Ignatian Spirituality). The results of this study are as follows: first, “the death of neighbor”, a illumination of suicide phenomenon and suicide attempters is seen as neighbor who is easily placed in blind spots and disappearing into the extreme choices surrounded by interpersonal disinterest and isolation, even if a small problem arises, it can lead to the emergence of adult suicide risks linked to childhood abuse experience and vulnerable safety nets. Second, “the encounter with a family members bereaved by suicide”, a meaning of the families who are grieving after the suicide of a precious family is seen as the families living in complicated grief, constantly recurring back to the reasons for the suicide of a family member and the maladjusted situation of the families who were unable to express their grief and mourning over the stigma of suicide. Internal examen and discerning heart at the counseling field became the basis of the theme of “the preferential concern for neighboring life and death” after a process of community-dimensional discernment with lay people in Catholic Church. Three realms, as the practical alternatives, presented along with the role of laity included ‘the spirituality of listening of the sound of life’ that listening to the needy, ‘the spirituality of life growing’ that eradicating domestic violence and child maltreatment, and “spirit of caring for life” that practising substantive helping to the poor and suicidal survivors. This is the path of the Catholic Church Community that need to be achieved.

치과는 가까이 있지만 심리적으로 접근하기 힘든 곳이기도 하다. 본 연구는 치과를 방문하려고 하는 대부분의 환자가 스마트폰을 가지고 손쉽게 방문 전에 자기 정보를 등록하고 등록된 정보를 바탕으로 치위생 전문가는 환자의 상태를 진단하여 간단한 조치 내용을 알려주거나 필요하면 치과를 방문하여 진료를 받을 수 있게 하는 앱 개발에 관한 것이다. 환자들은 이 앱을 통해 비용과 시간을 절감할 수 있으며 치과와 IT 기술을 융합하는 차원에서 의미가 있다고 할 수 있다.

The hydraulic design optimization and performance analysis of mixed-flow pumps for waterjet marine vehicle propulsion has been carried out using mean streamline analysis and three-dimensional computational fluid dynamics (CFD) code. In the present study the conceptual design optimization has been formulated with a non-linear objective function to minimize the fluid dynamic losses and then the commercial CFD code was incorporated to allow for detailed flow dynamic phenomena in the pump system. New designed mixed-flow model pump has been tested in the laboratory. Predicted performance curves by the CFD code agree very well with experimental data for a newly designed mixed-flow pump over the normal operating conditions. The design and prediction methods presented herein can be used efficiently as a unified hydraulic design process of mixed-flow pumps for waterjet marine vehicle propulsion.

RCP (Reactor Coolant Pump) is the coolant circulation pump in the nuclear power plant. In general, pump is selected with a sufficient operation margin because it is controlled by the control valve. But, in the nuclear system, primary cooling system is operated without a control vale to improve the safety of the reactor. So, exact fluid system analysis is required to estimate the flow rate, pressure drop, NPSHa, slope of the performance curve and other requirements. At here, slope of the performance curve is important to ensure the normal operation during the life-time of the plant because the system curve is shifted during from the beginning of the plant to the end of plant. In the present study, Slope of the RCP performance curve is calculated based on the numerical simulation results. Two kinds of inlet pipe are used to calculate the pump performance: Straight pipe, elbow pipe. The slope of the performance curve with the straight pipe is steeper than that with the elbow pipe inlet.

A turbo blower, driven by a high-speed blushless DC motor, was designed as a efficient substitute of a ring blower or a roots blower. Computational analysis and performance tests have been performed to investigate performance characteristics of the blower. Experimental measurements showed that the blower has a good stability margin. This paper gives an outline of design, computational flow analysis and performance test for aerodynamic evaluation of the variable speed turboblower.

A circulating pump with installation space constraints was developed satisfying performance requirements such as flowrate, head and NPSHAv. The development procedures are composed of conceptual design, configuration design, performance analysis by CFD and performance test which were established in KIMM. The developed pump is OH4 type centrifugal pump which has a mixed-flow type impeller, a double volute and a rigid coupling. As a result of tests, the pump proved to meet all the requirements including space constraints and performance.
