Objectives : Effects of multiple trauma are complex and extend beyond core PTSD symptoms. However, few psychological instruments for trauma assessment address this issue of symptom complexity. The Trauma Symptom Checklist-40 (TSC-40) is a self-report scale that assesses wide range of symptoms associated with childhood or adult traumatic experience. The purpose of the present study was to evaluate the validity of the Korean Version of the TSC-40 in a sample of psychiatric outpatients. Methods : Data of 367 treatment-seeking patients with DSM-IV diagnoses were obtained from an outpatient department of psychiatric unit at a university hospital. The diagnoses were anxiety disorder, posttraumatic stress disorder, depressive disorder, adjustment disorder and others. Included in the psychometric data were the TSC-40, the Life events checklist, the Impact of Event Scale-Revised, the Zung's Self-report Depression Scale, and the Zung's Self-report Anxiety Scale. Cronbach's ${\alpha}$ for internal consistency were calculated. Convergent and concurrent validity was approached with correlation between the TSC-40 and other scales (PTSD, anxiety and depression). Results : Exploratory factor analysis of the Korean Version of TSC-40 extracted seven-factor structure accounted for 59.55% of total variance that was contextually similar to a six-factor structure and five-factor structure of the original English version. The Korean Version of TSC-40 demonstrated a high level of internal consistency. (Cronbach's ${\alpha}=0.94$) and good concurrent and convergent validity with another PTSD scale and anxiety and depression scales. Conclusions : Excellent construct validity of The Korean Version of TSC-40 was proved in this study. And subtle difference in the factor structure may reflect the cultural issues and the sample characteristics such as heterogeneous clinical population (including non-trauma related disorders) and outpatient status. Overall, this study demonstrated that the Korean version of TSC-40 is psychometrically sound and can be used for Korean clinical population.

Purpose : Febrile convulsions are a common pediatric neurological disease, and it is important to prevent such a disease by controlling the risk factors that may recur. A recent report states that influenza virus infections have a high probability of a relationship with febrile convulsions; therefore, it is necessary to identify the clinical properties of febrile convulsions in relation to domestic influenza virus infections. Methods : Between November 2005 and February 2008, children hospitalized because of febrile convulsions and subsequently confirmed to have influenza infections were enrolled as subjects (patient group, n=11). The control subjects were those admitted with influenza virus infections but no febrile convulsions (control group 1, n=46) and those who developed febrile convulsions without influenza virus infection (control group 2, n=53). Results : The patient group showed a higher maximum body temperature ($39.3{\pm}0.5^{\circ}C$), more histories of past febrile convulsions (72.7%), and a shorter total duration of fever ($2.9{\pm}1.2$ days) than control group 1. When multivariate analysis was performed, the probability of febrile convulsions was found to be as high as 225.9 times in patients who had influenza virus infections with a past history of febrile convulsions (OR=225.9, 95% CI: 1.7-4780.0, P<0.05). When patients with febrile convulsions were compared based on the symptoms of influenza virus infections, the patient group showed a shorter duration of fever ($0.9{\pm}0.7$ days) before convulsion than control group 2; these convulsions were mostly a recurrence of febrile convulsions. When multivariate analysis was performed, the cases with a past history of febrile convulsions showed 5.5 times (OR=5.5, 95% CI: 1.2-25.1, P=0.03) the probability of convulsions when infected with the influenza virus, and this probability decreased by 0.3 times over one-day increments of the febrile period until febrile convulsions (95% CI: 0.1-0.9, P=0.02). Maximum body temperature, total duration of fever, family history of febrile convulsions, and complex febrile convulsions did not show a statistical significance. Conclusion : In cases of pediatric influenza virus infection, the past history of febrile convulsions could be identified within the risk factor of recurrent febrile convulsions. Therefore, influenza vaccination of children having a past history of febrile convulsions will be helpful to avoid the recurrence of these convulsions.

The personal bio-information supplied from the PHD(Personal Health Device) for personal health management is very sensitive in relation to a personal living body in an aspect of privacy protection. On the assumption thai the information is about a patient, it is more serious problem if it is revealed to a third party. However. the established ISO (International Organizations for Standardization) standard protocol[1] in October 2009 has just considered a transmission part for mutual exchange of bio-information between individuals, but has never actually considered security elements. Accordingly, this paper is to show all sorts of security threats according to personal health management in the u-health environment and security requirements newly.

Understanding the genetic background of hearing loss is important since almost 50% of the cases of profound hearing loss are caused by genetic factors. Until now, more than 150 causative genes have been identified. In this review, classification of genetic hearing loss (syndromic versus non-syndromic, recessive versus dominant, X-linked and mitochondrial), pitfalls in elucidating causative genes, anatomy of the inner ear, introduction of the most common syndromic hearing loss, introduction of the most common non-syndromic hearing loss-causing genes, mitochondrial and multifactorial hearing losses were discussed. Moreover, clinical approaches to the patients with hereditary hearing loss and genetic counseling were also explained briefly. Finally, future directions of the hereditary hearing loss research in Korean population were presented.

Objective: This study aims to determine whether national patient safety indicators (PSIs) can be calculated. Methods: Using PSI criteria from Organization for Economic Co-Operation and Development (OECD) Health Technical Papers 19 based on the Agency for Healthcare Research and Quality (AHRQ), PSIs were identified in the Korean National Hospital Discharge In-depth Injury Survey (KNHDIIS) database for 875,622 inpatient admissions between 2004 and 2008. Logistic regression was used to estimate factors of variations for PSIs. Results: From 2004 to 2008, 3,084 PSI events of 8 PSIs occurred for over 80 thousands discharges. Rates per 1,000 events for decubitus ulcer (PSI3, 4.88), foreign body left during procedure (PSI5, 0.05), postoperative sepsis (PSI13, 1.32), birth trauma-injury to neonate (PSI17, 7.92) and obstetric trauma-vaginal delivery (PSI18, 32.81) are all identified between ranges from maximum to minimum of OECD rates, respectively. However, rates per 1,000 events for selected infections due to medical care (PSI7, 0.22), postoperative pulmonary embolism or deep vein thrombosis (PSI12, 0.90) and accidental puncture or laceration (PSI15, 0.71) are below the minimum of OECD range. 7 PSIs except PSI 18 showed statistically significant relationship with number of secondary diagnoses. When adjusting patient characteristics, there are statistically significant different rates according to bed size or location of hospitals. Conclusion: This is the first empirical study to identify nationally number of adverse events and PSIs using administrative database. While many factors influencing these results such as quality of data, clinical data and so on are remain, the results indicate opportunities for estimate national statistics for patient safety. Furthermore outcome research such as mortality related to adverse events is needed based on results of this study.

Purpose: The study aims to evaluate the effects of Tai Chi applied cardiac rehabilitation program(TCCRP) on cardiovascular risks, recurrence risk in ten years, and cardiac specific quality of life in individuals with coronary artery disease. Methods: The sample was comprised of individuals diagnosed with coronary artery disease within six months of the study who were referred by their primary physicians to participate in the TCCRP. The design was a pretest/posttest with non-equivalent groups with 30 in TCCRP program and 33 wait-listed comparison group. Results: The average age of all participants was sixty seven years. At the completion of the TCCRP, the Tai Chi group showed significant reduction in their ten year recurrent risk for coronary artery disease measured by Framingham's algorithm. The quality of life for the experimental group was reported as significantly higher than the comparison group, especially the area of general symptom. Conclusion: The outpatient cardiac rehabilitation with Tai Chi was applied effectively and safely without any complication to individuals with coronary artery disease. Tai Chi can be useful as an alternative exercise for cardiac rehabilitation program which may provide more access to individuals for cardiovascular risk management in the community settings.

The behaviors associated with illness are different depend upon individuals even if Patients complaints same symptoms and have same disease. Understanding the patterns of those behaviors become one of the important elements in determining the diagnostic and treatment approaches and treatment compliance. The sick role plays a essencial part in abnormal illness behavior. The characteristics of abnormal illness behavior ran be applied to many parts in medicine. In case of the various kinds of functional disorders whose organic foundations are obscure and in applying the cognitive therapy, rehabilitation program and occupational therapy, the assessment and evaluation of the abnormal illness behvior is known to be beneficial. For improving the comprehensive psychiatric treatments which could be applied to the Koreans more effectively in patients with somatoform disorders and other various kinds of neurotic disorders further researches especially on the medico-historical and socio-cultural aspects of the illness behavior should be followed. And understanding the abnormal illness behavior would be helpful in enhancing the medical cost effectiveness.

The resistance to dentistry is as old as the history of dentistry. Historically, dental treatment techniques have continued to evolve to minimize pain with effective treatment, but the negative perception of dentistry has not been reduced as much as the development of technology. Particularly, children have a lack of resistance to external stimuli, mental development and patience, and the degree of cooperation with dental care is reduced due to changes in parenting methods including parental influence, so can experience DFA(dental fear and anxiety) and DBMP(dental behavior management problem). Among the various stimuli experienced by the child in the dentist, psychological factors affecting the dentist, dental clinic, and social factors affect the formation of the relationship with the dentist. Especially in recent years, the addiction related to smartphone is emerging as a social problem, and the effects of smartphone addiction on the oral cavity and the effects on dental behavior are examined.
