Abusive head trauma (AHT) in infants, especially acute subdural hematoma, has an extremely poor outcome. The most decisive and important finding is the appearance of a widespread low-density area on head computed tomography. This phenomenon was traditionally thought to be caused by cerebral ischemia. However, many other pathophysiological abnormalities have been found to be intricately involved. Recent studies have found that status epilepticus and hyperperfusion injures are the major causes. Another serious problem associated with AHT is cardiopulmonary arrest (CPA). Many infants are reported to visit to the hospital with CPA, and its pathophysiology has not been fully elucidated. This paper examines the background of these pathological conditions and associated factors and elucidate the pathophysiological mechanisms resulting in poor outcomes in AHT. In addition to the intensity of assault on the head, the peculiar pathophysiological characteristics in infants, as well as the social background specific to child abuse, are found to be associated with poor outcome.

Objectives : This study aims to identify temperament and characteristics of cannabis and methamphetamine abusers for elucidating psycho-biological variables related to certain substance abuse. Methods : A total of 320 patients who registered in the 'Hepatitis C cohorts study of intravenous drug users' between March 2006 and March 2010 participated in this study. Data on demographic variables were obtained and the Temperament and Character Inventory (TCI) and measures for nicotine dependence, alcohol dependence, depression and anxiety were assessed. After comparing TCI between cannabis, methamphetamine, and co-abusers, correlations between TCI and other clinical variables were examined. Results : The methamphetamine abuser group showed significantly higher scores in Novelty Seeking (NS2) and Harm Avoidance (HA3) in temperament than the cannabis abuser and co-abuser groups, whereas the cannabis abuser group had higher scores in purposefulness (SD2), congruent second nature (SD5), and self-directedness (SD) in character than the methamphetamine abuser group. In addition, temperaments and characters correlated with various psychiatric symptoms. Conclusions : We found the differences in temperament and characters among cannabis abusers, methamphetamine abusers. These findings might contribute to further understanding of mechanisms of cannabis and methamphetamine abuse.

The purpose of this study was to develop prevention and educational programs for battered women. The first stage was to assess battered women's health status and health needs. The second stage was to develop prevention and educational programs to improve battered women's health. A survey research design was used to gather data from June-November 1999 by the counselor. Research sample was recruited from shelter and women's counseling centers in Seoul, Inchon, Chooncheon, Taejeon, and Jeoju. Trained counselors contacted 218 women, who agreed verbally to participate in the study. The researcher did a literature review and developed the tool used. We did ten pretests and three counselors checked the tool for content validity. The reliability and validity of the instrument were acceptable. The second stage of the research consisted of lay-professional groups discussing the abuse problems and possible solutions. Each group had five professionals (counsellor, nurse, minister, psychiatrist, social worker) and five women who have experienced battering from her husband in community. Result of the survey and two(lay persons and professionals) group discussions showed that victims need more assessment of physical, mental and spiritual needs. Victims were beaten more often during their pregnancies than at other times. Various kind of strategy were frequently utilized, but still the number of women abused and suicides committed increased. Both studies showed that the women experienced severe beating, that they felt powerless, that they need to understand that society abuser characteristics, that they lack a protection support system and that society lacks would an understanding of battered women. Based on the result of both studies, we developed model for prevention and education of battered women. This educational program will increase women s power to solve the abuse problems. The ultimate goal of the program is to develop a one-stop center to give wholistic approach care to women in abuse situations.

The objective of this study was to evaluate the effects of a short-term/extreme temperature abuse (STA) on color characteristics and oxidative stability of aged beef muscles during simulated retail display. Two beef muscles (longissimus lumborum, LL and semitendinosus, ST) were aged for 7 (A7), 14 (A14), 21 (A21), and 28 d (A28), and further displayed at 2℃ for 7 d. The STA was induced by placing steak samples at 20℃ for 1 h on the 4th d of display. Instrumental and visual color evaluations, ferric ion reducing capacity (FRC) and 2-thiobarbituric acid reactive substances (TBARS) assay were performed. Initially, redness, yellowness and hue angle of all beef muscles were similar, regardless of aging time before display (p>0.05). An increase in postmortem aging time increased lipid oxidation and caused a rapid discoloration after STA during display (p<0.05). ST muscle was more sharply discolored and oxidized after STA, when compared to LL muscle (p<0.05). The FRC value of beef muscles was decreased after 7 d of display (p<0.05). The results from the current study indicate adverse impacts of postmortem aging on color and oxidative stabilities of beef muscles, particularly under temperature abusing conditions during retail display. Thus, developing a specific post-harvest strategy to control quality attributes in retail levels for different muscle types and aging conditions would be required.

Drug abuse and its related problems are increasing continuously in Korea. One of the most frequently abused drugs is methamphetamine, but there are few medical report in Korea. This is the first report of the identification of methamphetamine in the blood of a patient who had a return of spontaneous circulation after cardiac arrest and survived discharge. A 33-year-old male arrived at the emergency department presenting with chest pain and dyspnea. He had ingested methamphetamine and alcohol approximately 7 hours before arrival. One hour after arrival, he had seizure followed by cardiac arrest. Spontaneous circulation was recovered after 4 minutes of CPR. An analysis of the National Forensic Service identified plasma methamphetamine with an estimated average concentration of plasma methamphetamine at the time of arrival of 0.6 mg/L, a lethal dose. He had rhabdomyolysis and acute kidney injury but survived after continuous renal replacement therapy. Since then, he has suffered chronic kidney disease, and he is being followed up at the out-patient department. In Korea, although drug abuse is still uncommon, it is on the increase. Therefore, emergency physicians should be aware of the clinical characteristics of methamphetamine poisoning.

Purpose: The purpose of this study was to determine the relationship between customer contact service and mental health among Korean taxi drivers. Methods: This was a secondary analysis of data collected from the 2015 Korean Working Conditions Survey. The sample included 496 taxi drivers in South Korea. The effect of customer contact service on mental health was analyzed using logistic regression analysis. The independent variables were general characteristics, working conditions, and hazardous factors in interactive service. Results: The prevalence of poor mental health was 56.3%. Taxi drivers experienced emotional involvement (17.2%), hiding feeling (32.0%), and contact with angry clients (18.3%) in their job. During the first month of their work, 33.7% experienced verbal abuse and 12.3% threats/humiliating behaviors. In bivariate analysis, verbal abuse, threats/humiliating behaviors, and physical violence were associated with mental health of taxi drivers. Multiple logistic regression analysis revealed 'emotional involvement' and 'contact with angry clients' were significant predictors of mental health. Conclusion: The findings of this study may be useful in developing intervention programs to improve the mental health of taxi drivers in South Korea.
