This research examined perceived-being-accepted and perceived-being-rejected in depressive processes. There are two hypotheses and one assumes perceived-being-accepted and perceived-being-rejected as causes participating in depression. Another presupposes that they are the phenomena as results which accompany to depressive process. Then, the author, adjusting the influence of the depression to precede (time 1), examined the influence which perceived-being-accepted and perceived-being-rejected (time 2) have on later depression (time 3). 260 undergraduates participated in three times research. In the result of partial correlation analysis, adjusting the influence of the depression to precede perceived-being-accepted and perceived-being-rejected predicted later depression. It suggested that perceived-being-accepted and perceived-being-rejected would be the causes of depression.

The role of self-help group has been identified as having a buffering effect for individuals experiencing psychosocial transitions or stressevents. Bereaved parents were reluctant to talk of their interactions with their deceased children in the presence of people for whom their experiences seemed "crazy." When the experiences are normalized in settings such as self-help group meetings, they eagerly share the experiences as good parts of their lives. Data from this study are drawn from a long-term ethnographic study of the Gentle Breeze-Chiisana Kaze No Kai, a self-help group of parents whose child have died.

One of most important features in quantum computation might be said to be the linearity of state transitions. This feature strongly suggests a possibility such that linear circuits may give a new computational machinery with natural parallelism. The present article describes such a possibility. After noting that linear circuits with two-terminals may realize a linear mapping represented by a diagonal matrix, we show how to build both of one bit unitary operation and Controlled-NOT. Based on these facts it will be proved that the computation ability of linear circuits is not less than that of Turing machines and the number of computational steps of linear circuits is equal to or less than the one of quantum computation. Based on these facts, the NP complete problem such as TSP is shown to be solved within the polynomial time in the sense of linear circuits.

This paper investigates the meanings and the forms of Old English prepositional phrases of time introduced by on, Æt, to and in. The source of data is the Parker MS. of the Anglo-Saxon Chronicle. It was found that the preposition on governs both the accusative and the dative and is used overwhelmingly to denote time, showing the widest distribution of use. But it is not clear whether differences in grammatical case correspond to distinctions in meaning. Æt occurs only with cirr or cierr to govern the dative. Though its distribution is the smallest among the three prepositions, Æt has its own field of distribution. To governs the dative, and partially overlaps with on in terms of distribution. But it is the only one, among the all the prepositions examined in the present study, that implies a future-orientation. The distribution of in overlaps with that of on, and seems to be subsumed by it. Though the total number of examples is the smallest, in governs both the accusative and the dative.
