Hydrogen absorption experiments were carried out by the titanium(Ti) sponge for investigating the characteristics of hydrogen absorption. From experimental results, Ti sponges showed the high hydrogen absorption capacity inspite of low reaction temperature. The H/M which mean the capacity of hydrogen absorption was measured 2.0 for Ti sponge in the experimental condition of 25℃. The effects of the reaction temperature, activation conditions, and the presence of helium in the hydrogen were investigated.

A mathematical model was studied to predict flow rate, heat transfer and heat of combustion in rotary kiln incinerator. For the design of equipments and for the optimum operating conditions, it is necessary to understand the combustion status such as the transient temperature distribution and the degree of combustion. The objective of this study is to establish the combustion model that can be used for design and performance evaluation of incinerator. And also, numerical analysis to be able to understand heat transfer phenomena in the rotary kiln incinerator was performed in this study.

Disc displacement in temporomandibular joint surgery has been troublesome. Problems-migration, foreign body reation, bony erosion, secondary pain & swelling, fragmention etc.-have occured. The autogenous graft, rather than alloplastic materials, may be the material of choice when replacement of the temporomandibular joint disc is indicated. The technique and results of replacement of the articular disc by autogenous ear cartilage are presented. In the three patients-five joint-operated with a follow up from eleven to twelve months, all patient were improved in postoerative symptoms, mouth opening ranges and jaw functions. The autogenous ear cartilage appeared to be a suitable autogenous tissue graft, maintaining its viability and functioning as an interpositioning material between the condyle and fossa.
