With the advancement in modern information technology, virtual reality (VR) is being increasingly used for the diagnosis, assessment, and treatment of mental disorders. Recently, a VR-based cognitive behavioral therapy for social phobia has been recognized as a new medical technology in South Korea. This might lead to an increase in the use of VR in the field of psychiatry. The present review provides an overview of the status of VR therapies in various psychiatric conditions such as anxiety disorder, post-traumatic stress disorder, psychosis, addiction, and eating disorder. Besides, it summarizes the role of VR therapy in the management of disorders associated with child and adolescence psychiatry as well as various other clinical applications. Additionally, we discuss the merits and limitations of VR therapy, which might serve as a useful reference for researchers. In the current environment wherein novel medical models consisting of a combination of digital devices and medicine are being developed; understanding new technologies such as VR could open new doors to mental health treatments.

Purpose: This study was done to explore factors related to amount of service use for elders with long-term care needs. Methods: A descriptive-correlation design was used. The sample included 259 elders and their primary caregivers who had cared for the elders for at least 6 months. Data on long-term care need assessment, service use and interviews with primary caregivers were analyzed. Results: There was no significant relationship between the sociodemographic characteristics and the amount of services use. Amount of service use differed significantly by Long-term care classification. The mean scores for class 1, 2 and 3 were 22.68, 21.47 and 17.87 days respectively. Primary caregiver relationship with the elders and the number of family-friend helpers were also significant. Multivariate regression analysis showed that gender, marital status, activities of daily living, cognitive impairment, and secondary caregiver support explained 17% of the total variance of service use among these elders (F=3.50, p<.001). Conclusion: The results of this study indicate that critical factors including secondary caregiver support and individual background, and other functional dependencies except for physical function should be considered in accurately predicting the amount of service use for community dwelling elders with long-term care needs.

Purpose: This study was done to explore factors relating to number of falls among community-dwelling elders, based on gender. Methods: Participants were 403 older community dwellers (male=206, female=197) aged 60 or above. In this study, 8 variables were identified as predictive factors that can result in an elderly person falling and as such, supports previous studies. The 8 variables were categorized as, exogenous variables; perceived health status, somatization, depression, physical performance, and cognitive state, and endogenous variables; fear of falling, ADL & IADL and frequency of falls. Results: For men, ability to perform ADL & IADL (${\beta}_{32}$=1.84, p<.001) accounted for 16% of the variance in the number of falls. For women, fear of falling (${\beta}_{31}$=0.14, p<.05) and ability to perform ADL & IADL (${\beta}_{32}$=1.01, p<.001) significantly contributed to the number of falls, accounting for 15% of the variance in the number of falls. Conclusion: The findings from this study confirm the gender-based fall prediction model as comprehensive in relation to community-dwelling elders. The fall prediction model can effectively contribute to future studies in developing fall prediction and intervention programs.

Purpose: In Korea, as the number of hypertensive worker grows, identifying the level of health promoting life style practice and related factors in hypertensive workers is becoming more and more important. Method: The subjects of this study were 195 hypertensive male workers in Korea. The data was collected during 3 months ranging from August 2003 to October 2003. The data was analyzed by descriptive statistics. t-test, ANOVA. Pearson's correlation coefficient and stepwise multiple regression by SAS 8.1 program. Results: It was found that there were significant differences between age, religion, medication, perceived health status, perceived benefits, internal health locus of control, powerful other health locus of control and health promoting life style practice. The most significant factor affecting the health promoting life style practice was internal health locus of control. The combination of internal health locus of control, specific self-efficacy, powerful other health locus of control, general self-efficacy accounted for 51.0% of the health promoting life style practice. Conclusion: The level of health promoting life style practice was very low, so it is urgent to manage and care for hypertensive male workers continuously and systemically with occupational health nurses. Based on the above results, cognitive perceptual characteristics should be considered when developing health education programs for hypertensive workers.

Purpose: The purpose of this study was to investigate the actual condition of the disabled due to Occupational accidents based on the functional evaluation tool. Method: The data were collected from 2 Workers Accident Medical Corporation, 311 subjects between February and August, 2007. The tool comprised of six components including physical function, cognitive function, communication, emotional and disturbing behavior, nursing skills and rehabilitation needs. Results: Among the disabled, the average point of physical function of 5 was found in 61.92% and to express and understand were evaluated as normal in 36.69% and 33.44%, respectively. Also, hearing and vision were evaluated as normal in 53.50% and 37.98%, respectively. 19.01% of the disabled had emotional problems and 13.78% had disturbing behavior. Most disabled were in need of nursing skills with 97.73% ROM and activities. The 78.18% and 76.90% of disabled were in need of rehabilitation because of right and left leg in full movement disorders, respectively. Conclusion: The evaluation score for the disabled caused by Occupational accidents was diverse showing 10 to 19 points and 140 to 150 points. The result means the care cost should be determined depending on the care needs of the disabled because there is such a diverse range of care needs for them.

With a long sensing period, the inter-frame spectrum sensing in IEEE 802.22 standard is vulnerable to the effect of the traffic of the primary user (PU). In this article, we address the two degrading factors that affect the inter-frame sensing performance with respect to the random arrival/leaving of the PU traffic. They are the noise-only samples under the random arrival traffic, and the PU-signal-contained samples under the random leaving traffic. We propose the model in which the intra-frame sensing cooperates with the inter-frame one, and the inter-frame sensing uses the time-of-arrival (ToA), and time-of-leave (ToL) detectors to reduce the two degrading factors in the inter-frame sensing time. These ToA and ToL detectors are used to search for the sample which contains either the ToA or ToL of the PU traffic, respectively, which allows the partial cancelation of the unnecessary samples. At the final stage, the remaining samples are input into a primary user detector, which is based on the energy detection scheme, to determine the status of PU traffic in the inter-frame sensing time. The analysis and the simulation results show that the proposed scheme enhances the spectrum-sensing performance compared to the conventional counter-part.
