The dependency structure matrix (DSM) was invented for optimizing product development processes. Although it has broader applications – including, as we shall see, to software – we shall describe it in its original context to make the discussion as concrete as possible.
In the development of a product, a collection of tasks is performed. Thes

The diagnosis of ischaemic heart disease underlying particular symptoms depends largely on the nature of the symptoms. The first investigation is an electrocardiogram (ECG/EKG), both for "stable" angina and acute coronary syndrome. An X-ray of the chest an

So we investigated how the isolation of the elderly is connected to the suicide of the aged and what mechanism is exist in that process. In our study, we focused on confirming the risk factors of elderly suicide to come up with the preventi
