The goal of this study is to examine the impact of self-esteem, self-efficacy, and attributional disposition on communication apprehension in college students. The research problems were verified by correlation analysis and multivariate regression analysis. A questionnaire survey was conducted on 239 college students. The findings are as follows: First, the higher level group in the self-esteem and self-efficacy have lower communication apprehension scores than the lower level group. Particularly, it is found that self-confidence in self-efficacy variables has the greatest effect on communication apprehension. Second, college students with high internal attributional disposition tend to feel less communication apprehension, while college students with high other's attributional disposition and accidental attributional disposition tend to have higher communication apprehension. Third, as a result of examining the relative effects of self-esteem, self-efficacy, and attributional disposition on communication apprehension, self-efficacy is found to have the greatest effect.

In this paper, we design and implement complement based speech training system for voice disorder. The system consists of three level of training: precedent training, training for speech apprehension and training for speech enhancement. To analyze speech of voice disorder, we extracted speech features as loudness, amplitude, pitch using digital signal processing technique. Extracted features are converted to graphic interface for visual feedback of speech by the system.

Tremors are trembling movements and are seen in association with alcoholic intoxication, certain drugs, thyrotoxicosis, multiple sclerosis, hysteria, and nervous tension. Dental fears, such as, pain, drill, unknown, dependency, helplessness, mutilation and oral change, induce the neuroendocrine response (release of epinephrine and norepinephrine, etc). The clinical manifestations of epinephrine or other vasopressor overdose include : anxiety, tenseness, restlessness, throbbing headache, tremor, perspiration, weakness, dizziness, pallor, palpitation and respiratory difficulty. Signs of local anesthetic overdose appear clinically whenever the anesthetic level in the blood rises to an appropriate level in an individual. The clinical signs of moderate overdose levels include : talkativeness, apprehension, excitability, slurred speech, tremor and muscular twitching. This is a case report about the severe tremor care after the endodontic treatment under right mandibular block anesthesia in a 56-years old female patient.
