In psychology it is common to use the term "crisis" when describing human behavior in any extreme situation. The term "crisis", however, is not infrequently used in such a way as "identity crisis" or "growth crisis". It is noted from this that the conception of "crisis" does not always apply to sudden critical situations in which body and mind suffer acute danger or suspense. It is, therefore, advisable to avoid the confusion of the concept by using the phrase "extreme situation" as distinguished from "crisis" in the studies of these fields. Various studies have been made so far about extreme situations studies on disaster psychology, prisoners' psychology and other special studies as well as experimental basic studies. All these studies aim at understanding human behavior in extreme situations, but they are not yet fully interrelated to one another. We would like to propose that, in future, we should make efforts toward systematizing all these studies into one synthesis under the denotation of "Extremity Psychology".

The difference in the tissue reaction in the tissue-titanium interface between mature (22-week-old) and young (6-week-old) rats was examined by using light microscopy with decalcifiedsemi-thin sections (1μm) and undecalcified sections (40μm) and scanning electron microscopy (SEM). A titanium implant (diameter=1.0mm: height=1.5mm) was inserted into a tibia.Rats in both groups were killed on the 1st, 3rd, 5th, 7th, 14th and 28th day after operation. The bonycontact ratio and area and thickness of the newly formed bones in the undecalcified section weremeasured with an image analysis system.On the 5th day, calcification in newly formed tissue was observed in young rats, and on the 7thday, in mature rats. On the 7th day, the mass of bone-like tissue in the mature rats was smaller thanthat in young rats. On the 28th day, the implant in both rats was almost enclosed circumferentiallywith newly-formed bone (thickness=20-30μm). However, by the image analysis, the bonycontact ratio and the area of newly formed bone in the mature rats were significantly smaller thanthose in the young rats. SEM revealed collagenous fibril-like structures (thickness=2-5μm) inthe bone-titanium interface of the mature rats, but obscure structures (thickness=0.4-0.6μm) inthat of the young rats.
