Recently A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. ECG and HRV are used in most virtual reality system. GSR is electrical impedance of biological tissues and the changes in impedance accompanying physiological activity. GSR is better than ECG or HRV for explaining mental states in other study. In this study, we will analysis GSR signal when a acrophobia patient and a normal is on high floor.

We dentists perform many of routine dental procedures and must deal with much of the population's dental anxiety and fear. Dentists have used many non-pharmacological modalities initially to overcome anxiety and fear, including distraction, empathy, desensitization, and so on. However, certain patients need pharmacological backup of anxiety and fear to conquer dental treatment. This article presents four cases to introduce the methods from nitrous oxide and oxygen inhalation to general anesthesia for difficult adult dental phobic patients to deal with.

Acrophobia is an abnormal fear of heights. Medications or cognitive-behavior methods have been mainly used as a treatment. Lately the virtual reality technology has been applied to that kind of anxiety disorders. A virtual environment provides patient with stimuli which arouses phobia, and exposing to that environment makes him having ability to over come the fear. Recently, the patient can take diagnose from a medical doctor in distance with the telemedicine system. The hospital and doctors can get the medical data, audio, video, signals in the actual examination room or operating room via a live interactive system. Audio visual and multimedia conference service, online questionary, ECG signal transfer system, update system are needed in this system. Virtual reality simulation system that composed with a position sensor, head mount display, and audio system, is also included in this telemedicine system. In this study, we tried this system to the acrophobia patient in distance.

Anxiety and phobia in dental procedures are common deterrents for patients visiting the dental care unit. For these individuals, procedural sedation may aid in completion of dental treatments. In most cases, the patients are conscious during sedation, thereby allowing spontaneous ventilation. Intravenous sedation (IVS) is widely used during dental treatment to relieve patient anxiety. IVS is the most effective route of administration to achieve this goal, but it requires advanced training, more than that provided during undergraduate education. During IVS, rapid onset, repetitive drug administration, easy titration, and rapid recovery from sedation can be achieved. However, conscious sedation during IVS can result in deep sedation that can cause respiratory and cardiovascular depression. Therefore, the characteristics of intravenous sedatives should be known. The purpose of this review is to discuss the characteristics and usage of intravenous sedatives currently used for dental procedures.

This article discusses the issues of benefit and possibility of application of patient-controlled sedation (PCS) for the dental treatment. The purpose of administering PCS for patients is to diminish anxiety and to provide cooperative and effective dental treatment. But there are a lot of barriers to application of PCS such as knowledge about pharmacokinetics of sedatives, expensive high speed and patient-controllable syringe pump, and well educated sedationist. And there could be risk of deep sedation, airway obstruction and hypoxic brain damages, etc. In order to decrease incidence of complication, appropriate drug selection, selection of right bolus dose, lock-out time is much important.

The purpose of this study was to analysis on the victims of sexual violence. Data was obtained from the interview resources between January 2001 and June 2003. Data were analyzed using SPSS program. The major findings of this study were as follows. The most of sexual violence was female. The sexual violence occurred mainly from victim circumference but, the report was low. Type of sexual violence was many rape and sexual harassment. Therefore, sexual violence victims mainly visited an obstetric & gynecologic clinic. Injuries of sexual violence were physical (rupture of the hymen and vaginal injury), psychological (phobia, anxiety and confusion) and sexual (retire from the world) injuries. The results will be useful to furnish a guideline for prevent sexual violence.

The purpose of the present study was to investigate empirically the relationship among self-image, depression, anxiety, and social sensitivity in adolescents. 1602 normal adolescents(697 males and 905 females) responded to self report scales-Offer Self-Image Questionnaire-Revised, 3 subscales of Symptom Checklist-90-Revised. The data were analyzed with ANOVA and LISREL to examine the effect of self-image on depression, anxiety, and social sensitivity, and to test the relationship among the above 4 variables. Adolescents with low self-image showed significantly higher scores in the scales of depression, anxiety, and social sensitivity than did adolescents with high self-image. The result of LISREL showed that the low self-image leads to the emotional state of depression and anxiety, and those of depression and anxiety lead to the increase of social sensitivity, suggesting that self-image has a direct effect on depression and anxiety, and has a direct effect on social sensitivity in adolescent. These results were discussed in terms of implications for the prevention and treatment of adolescent social phobia.

This study observes the psychological changes of unemployed people according to their unemployment period. With this what psychological changes they face according to their unemployment period and what psychological characteristics they show, whether if psychological changes and job hunting activities are in relation, and whether if psychological changes affect job hunting activities. The study subjects received unemployment wage and were divided according to before employment, 1~3 months unemployed, and 4 months or more unemployed. An in-depth research of 8 people was conducted within the period of 2017.05~08. The psychological characteristics of people, in the period from when they first sense unemployment possibilities until three months of unemployment, are anger, anxiety, fear, which is a mixed characteristic that does not disappear but continues deepening. In study there was no significant difference in depression, anxiety, anger, social phobia, alcohol, religion factors, low self-esteem, and low self-efficacy in before employment, 1~3 months unemployed, and 4 months or more unemployed. However, the average levels of anger anxiety, depression, and social phobia were higher when the unemployment period was longer and the results of low self-esteem and low self-efficacy support further research.

Background: People with special needs tend to require diverse behavioral management in dentistry. They may feel anxious or uncomfortable or may not respond to any communication with the dentists. Patients with medical, physical, or psychological disorders may not cooperate and therefore require sedation (SED) or general anesthesia (GA) to receive dental treatment. Using the healthcare big data in Korea, this study aimed to analyze the trends of SED and GA in special needs patients undergoing dental treatment. It is believed that these data can be used as reference material for hospitals and for preparation of guidelines and related policy decisions of associations or governments for special needs patients in dentistry. Methods: The study used selected health information data provided by the Korean National Health Insurance Service. Patients with a record of use of one of the eight selected drugs used in dental SED between January 2007 and September 2019, those with International Classification of Diseases-10 codes for attention deficit hyperactivity disorder (ADHD), phobia, brain disease, cerebral palsy, epilepsy, genetic disease, autism, mental disorder, mental retardation, and dementia were selected. The insurance claims data were analyzed for age, sex, sedative use, GA, year, and institution. Results: The number of special needs patients who received dental treatment under SED or GA from January 2007 to September 2019 was 116,623. Number of SED cases was 136,018, performed on 69,265 patients, and the number of GA cases was 56,308, implemented on 47,257 patients. In 2007, 3100 special needs patients received dental treatment under SED while in 2018 the number of cases increased 6 times to 18,528 SED cases. In dentistry, ADHD was the most common disability for SED cases while phobia was the most common cause of disability for GA. The male-to-female ratio with respect to SED cases was higher for males (M : F = 64.36% : 35.64%). Conclusion: The application of the SED method and GA for patients with special needs in dentistry is increasing rapidly; thus, preparing guidelines and reinforcing the education and system are necessary.
