This paper presents an experimental study of the factors modulating the urgency perception of voice alarm generated by concatenative synthesizers. Four experiments were conducted using psycho-physical approach in which 105 participants made magnitude estimation for urgency perception of various voice alarm stimuli. Experiment 1 identified 6 acoustic and non-acoustic factors modulating the perceived urgency of synthesized voice alarm. Experiment 2, 3 and 4 quantified the relations between the objective changes in each of the quantifiable parameters and the subjective changes in urgency perception. This research has implications for the design and implementation of synthesized voice alarm systems where urgency mapping is required.

Several studies of eye-slaved nonverbal communicators have been performed recently. By integrating the eye and head-position monitoring devices, the present authors had developed an eye-controlled human/computer interface based on the line-of-sight and an intentional blink to invoke commands in the preceeding study. As a successive study, this paper examines the characteristics of performing the intentional double blinks experimentally and proposes the double blinks as an alternative triggering method. The applications may extend to several domains such as rehabilitation and virtual reality system with head mounted display.

N/A The clinical features and laboratory findings of 123 patients with histologica]ly confirmed Hashimoto's thyroiditis were examined from April 1984 to December 1987 at the Masan Koryo General Hospital. The results were as follows: 1) All 123 patients with Hashimoto's thyroiditis were women and the age distribution showed the peak incidence between the second and fourth decades (Average of 35 years). 2) Eighty-four cases (68.3%) had a moderately diffuse goiter, 106 cases (86.2%) firm and 98 cases (79.7%) had symmetrical swelling of the glands. Thirty-Seven cases (30.1%) were palpated as nodular surfaced thyroids. 3) All 123 patients could be divided into three groups according to the thyroid function test on initial visits, i. e. euthyroid 59 cases (48.0%); hypothyroid, 49 cases (39.8%) and hyperthyroid, 15 cases (12.2%), 4) The positive rate for antithyroglobulin and antimicrosomal antibody were 30.8% and 74.5%. The difference in the titer of antibodies according to the thyroid function status could not be observed. 5) One hundred thyroid scans were studied and classified into the following groups: 48 cases (48%) showed diffuse enlargement with inhomogeneous uptake, 18 cases (18%) showed diffuse enlargement with increased uptake, 16 cases (16%) showed normal appearance, 13 cases (13%) showed cold areas, and 5 cases (5%) showed both lobes faintly visualized. 6) The thyroid needle biopsy is considered as a safe, important diagnostic tool for differential diagnosis and for determining the prognosis. 7) With thyroid hormone therapy, goiters were reduced and various symptoms were improved in the hypothyroid group.
