Objectives : The purpose of this study was to investigate important therapeutic factors in encounter group and compare these therapeutic factors with those in long-term outpatient group psychotherapy, to understand the content and process in real cases for facilitation of interpersonal learning which is important for long-term outpatient group psychotherapy, and to acquire basic data of long-term outpatient group psychotherapy on the basis of this understanding. Methods : The subject was 7 encounter groups, composed of 41 persons. We used short from of Yalom's Q-sort to find important therapeutic factors in encounter group. We selected 2 cases for analying the process and content in these cases. Results : Three of the most important therpeutic factors were existential factors', 'self understanding', and 'interpersonal learning(input)'. Conclusion : We suggest that interpersonal learning is the most important therapeutic factor in encounter group.

Worldwide energy consumption has been recently increasing enormously, especially in refrigeration and air conditioning industries. As a result of this increase, atmospheric hydrocarbon and other gas levels have increased so that they may be a source of world environmental problems. Therefore, new research was started to overcome the environmental problems, like the destruction of the ozone layer and the warming of Earth's temperature, by the use of natural refrigerants as substitutes for the freon refrigerant. In this paper, evaporation heat transfer of global heat pump using grooved inner tube was studied. New natural refrigerants R-290 and HCFC refrigerant R-22 were used. The local heat transfer coefficient was decreased according to the evaporation process. Moreover, the increment of heat transfer coefficient was found in R-290 refrigerant. Average heat transfer coefficient was obtained the higher value in R-290 refrigerant than R-22. Comparing the heat transfer coefficient between experimental result and simulation data of other's, the Shah's correlated equation was closely assimilated to the author's experimental results.

The accuracy of machinindg using grinding wheels depend upon the combined parameters that are depth of cut, the speed of workpiece and wheel, the state of wheel surface and kinds of grinding wheel. If this parameters apply inadequately for grinding work, it'll break out the abnormal states such as grinding crack and grinding burn. Therefore, this paper aims at analysing the variations of grinding forces that are closely concerned this abnormal states, proposing the normal and proper conditions of grinding work, an making up the economic grinding.

In this paper, first of all we compared psychoanalysis with psychodrama by a historical point of view. Next, we reviewed group psychotherapy generally and considered the position of psychodrama through the comparison with various types of group psychotherapy. On the basis of this consideration, we compared Yalom's group psychotherapy as a typical type of group psychotherapy with psychodrama. Lastly, we discussed the application of group psychotherapy and psychodrama to each other. Psychoanalysis, psychodrama, and group psychotherapy developed separately at similar times in different fields. Finally, these three fields met with one another in the field of psychiatry. Each of these three fields changed itself as a result of absorbing various things from one another. Therefore, nowadays these fields became to have a close relation with one another. Psychodrama is in a position as a type of group psychotherapies, so it is important to understand group psychotherapy generally for understanding psychodrama. Psychodrama has similar aspects to other group psychotherapies, but also has different aspects from other group psychotherapies. When we understand these aspects, we can conduct therapeutic works effectively in practice. Psychodrama's methods can be applied to group psychotherapy and group psychotherapy's theories can applied to psychodrama. When psychodrama and group psychotherapy takes good points from the other side they can make progress.

凍結溫度에 대한 植物의 反應과 生存戰略

식물은 여러 온도조건에서 생육하고 있으며 조직이 빙점 이하의 온도에 노출되면 내동성의 정도에 따라 다양한 피해정도를 나타내게 된다. 동결에 의한 식물세포의 피해과정을 과거 다양한 가설로 설명하여왔으나 최근에는 막의 이상접근이라는 공통된 현상을 기초로 한 가설로 설명하고 있다. 막의 이상접근을 동결상해의 원인으로 하면 저온순화에 의한 동결과정중에 세포에서 발생하는 구조변화 및 인공적인 동결보존과정에서의 동결상해 방어기구를 개념적으로 설명하는 것이 가능하다. 그러나 이 가설은 복잡한 생리기능을 나타내는 식물세포와 동결과정에서 발생하는 물리 화학적인 stress의 상호작용을 설명하기에는 아직 불충분하다. 한편, 식물은 동결이라는 극한상황에 적응하기 위하여 세포외동결이나 과냉각, 기관외동결로 대표되는 생존전략을 진화, 발전시켜 왔다. 어떤 생존전략을 선택하느냐에 따라서 식물이 적응, 생존할 수 있는 한계온도가 결정되며, 식물의 지리적 분포도 결정되다. 과냉각에 의해 내동성을 획득하는 경우 균질핵생성온도인 -40℃가 내동성의 한계가 되며, 기관외동결이나 세포외동결에 의한 내동성은 세포가 동결탈수에 저항할 수 있는 능력에 의해 결정되며 제한이 없다. 따라서 과냉각에 의해 내동성을 획득하고 있는 농작물의 재배지역의 한계는 과냉각특성을 이용한 재배적 기법이나 육종기법을 이용하여 세포외동결 및 기관외동결특성을 도입하는 방법 등에 의해 극복할 수 있을 것이다. 식물이 내동성을 획득하는 과정을 분자수준에서 분석하는 기법이 주목을 받고 있다. 저온에 감응한 세포에서 발생하는 유전자의 전사나 최종산물인 단백질 등을 분석하여 저온순화과정을 밝히고자 하는 노력으로 많은 단백질이 확인되었으나 이들이 내동성의 획득에 관여하는 역할은 아직 명확하지 않다. 한편에서는 내동성의 획득에 관련된 유전자를 cloning하여 형질전환 식물체의 육성이 시도되고 있다. 이와 같이 생명공학에 의해 가까운 미래에 생산성이 높고 내동성이 강한 식물을 창출하기 위해서도 내동성이라는 현상을 보다 명확히 할 필요가 있으며, 생물학을 시작으로 물리학, 화학 등의 광범위한 분야의 협력을 얻어 종합적으로 식물이 지니고 있는 동결이라는 극한상황에 대한 적응능력을 밝힐 필요가 있다.

The most important element is a rise ratio when regarding beauty and economics of arch bridges. Only the effect of dead load has been considered to decide the rise ratio. In this study, when going over the rise ratio of arch bridges, examined the problems, that the determination of the rise ratio by the dead load has, by adding the factor of a determination of optimum rise ratio, which is not only the effect of the dead load that has been currently considered but also the problem with respect to wind resistant dynamic stability that is now taken seriously. Synthetically, when deciding rise ratio that is investigated in basic step of design, it is not necessary to consider the evaluation wind resistant dynamic stability. Therefore the result of this research can be summarized as followes ; If it is identify oneself with rise ratio that the divided ratio due to the tie girder of the 3 continuous spans half-through steel arch bridges cannot cause a big effect in stability the wind resistant dynamic stability. If it is identify oneself with the relative stiffness ratio and girder depth ratio of the 3 continuous spans half-through steel arch bridges that the rise ratio proposes that it uses 0.10~0.30, divided ratio due to tie girder proposes that it uses 1.0~2.5 because of the wind resistant dynamic stability and the stress of the hanger. The rise ratio proposes that it uses 0.16~0.18 is given by the Japanese bridge construction association to obtained in investigation equation between an arch span length and the rise, using 0.1~0.2 at the basic design phase and the divided ratio which using 1.5 due to tie girder generally has been employed to main results and very well agrees with a research accomplishment results.

The objective of this study is to develop an automatic object changer unit to improve processing problems existed in the conventional horizontal machining center. In order to perform this objective, a upward and downward traverse unit in which a unit that consists of a motor and reducer, chain and sprocket wheel, and upper and lower base employed in an automatic object changer unit performs sliding contact motion in a frame was designed. To achieve this design, constraint conditions for the upward and downward traverse unit first designed. Then, an operation mechanism was designed and that was introduced as a sum of kinetic energy for the sprocket wheel and upper and lower base based on the moment of inertia, which is the kinetic energy of the converted upward and downward traverse unit in the side of the reducer. In addition, The work required to rotate the converted upward and downward traverse unit in the side of the reducer by one revolution can be calculated using the sum of work that is required in the sprocket wheel and upper and lower base that is a part of the upward and downward traverse unit. Furthermore, the converted equation of motion in the side of the motor can be introduced using the equation of motion using the converted upward and downward traverse unit in the side of the motor. Then, Then, a proper motor can be determined using predetermined specifications employed in the motor and several parameters in the upward and downward traverse unit in order to verify such predetermined specifications. Also, a design of a horizontal traverse unit that performs sliding motion on a upward and downward traverse unit and simulation that verifies the results of this design are required as a future study.
