PURPOSE: Although the overall incidence of hepatitis A in Korea has been decreasing recently, the adolescents born before the introduction of the hepatitis A vaccine remain to be highly vulnerable to outbreak. This study examines the unvaccinated adolescents' and their parents' knowledge and health beliefs toward hepatitis A vaccination. METHODS: Healthy adolescents aged 13-19 years old who had no previous history of hepatitis A vaccine and hepatitis A infection, and their parents or legal guardians were the subjects of the study. The survey was conducted using a structured questionnaire based on the Health Belief Model, and examined the subjects' demographics, knowledge, and health beliefs (i.e., perceived susceptibility, severity, benefits, and barriers). RESULTS: We included 157 adolescents and their parents/guardians (mean age: 16.0+/-1.6 and 45.6+/-4.7 years, respectively). The average knowledge item score for adolescents and parents was 6.4+/-3.7 and 7.3+/-3.4 (out of 18), respectively. Similarly, average Health Belief Model item scores were: susceptibility, 5.6+/-1.6 and 5.9+/-1.7 (range: 2-10); severity, 16.3+/-4.1 and 18.3+/-3.6 (range:5-25); benefits, 19.7+/-3.3 and 20.6+/-2.1 (range:5-25); and barriers, 41.3+/-8.9 and 39.0+/-9.1 (range:7-85). The major reason for not undergoing hepatitis A vaccination was lack of knowledge about its importance. CONCLUSIONS: Refresher health lectures about hepatitis A and the vaccine are needed by both the adolescents and their parents. Furthermore, the inclusion of hepatitis A vaccine in the national immunization program should be considered to reduce the risk of hepatitis A outbreak and to raise the vaccination coverage among the adolescents in Korea.

PURPOSE: The purpose of this study was to investigate the knowledge and practice level of infection managements in child guardians with respiratory infections after H1N1 diffusion of 2009. METHODS: The data were collected during February and March 2010 using a self-report questionnaire. The participants were 228 child guardians. Data were analyzed using frequency, percentage, means, SD, t-test, F-test, Pearson correlation coefficients, and Cronbach's alpha with the SPSS 17.0 program. RESULTS: Mean age of the guardians and children were 37.8 years, 4.1 years respectively. For knowledge level of respiratory infections, hand washing method had the highest score and snuffles prevention method, the lowest. For practice level for respiratory infections, environmental hygiene management had the highest score and symptom management, the lowest. Infection management knowledge and practice level had a positively significant correlation in every area. CONCLUSION: The results indicate the necessity of continual education on infection management, and that the most efficient timing for the education appears be for participants during their first pregnancy or after the woman has delivered her child.

A 24-year-old man presented with mental change, fever, abdominal pain, tenderness and palpable mass on the lower abdomen. He was a non-Korean engineer and did not accompany a legal guardian, so medical history taking was difficult due to his mental status. Brain magnetic resonance imaging showed multiple rim-enhanced lesions of the brain, and abdominal computed tomography showed huge paraspinal abscess. Chest X-ray and computed tomography showed poorly defined nodular opacities. We initially thought that this patient was infected with toxoplasmosis with typical cerebral image finding and immunoglobulin laboratory finding of cerebrospinal fluid and serum study. The abdominal abscess was confirmed as tuberculosis through the pathologic finding of caseous necrosis. We used anti-tuberculosis medication and anti-toxoplasmosis medication for almost 4 months, and then his clinical state and radiological findings were considerably improved.

Under new mental health and welfare law, involuntary admission is allowed only for persons with mental illness based on the narrowed criteria of mental illness when they meet both need for treatment and danger to themselves and others. These stringent danger criteria along with narrowed definition of mental illness may prevent timely intervention for people with acute psychosis. It is claimed that the danger criteria is essential to keep up with international (UN, WHO) principles for legislation of mental health acts and laws of advanced countries. The international principles, however, do not necessarily call for stringent danger criteria for involuntary hospitalization. Danger criteria are not also prerequisites for involuntary hospitalization in many advanced countries. In countries with strict danger criteria, complementary measures seem to be taken for the drawback of danger criteria. As for the involuntary hospitalization by legal guardians, the complicated qualification for legal guardians may hinder prompt admission. The required number of legal guardians also needs to be changed from two to one person. Even in the situation where involuntary hospitalization is deemed urgent, there is no way to transport the patients to the hospital for assessment or temporary admission unless the police judges the patients to be dangerous to themselves or others. Outpatient treatment order can be an alternative to involuntary admission. However, it is rarely used since the order cannot be applied to those who do not have history of admission due to danger. For voluntary admission, status conversion to involuntary admission needs to be allowed in case of aggravation of symptoms to meet involuntary admission criteria. In addition, informal admission needs to be introduced to avoid unnecessary formal procedures for patients admitting voluntarily to open ward. In view of all these issues with new mental health and welfare law, entire revision of new mental health law is urgent to balance the rights to proper treatments and protection of human rights of persons with mental disorder.

BACKGROUND/OBJECTIVES: This study aimed to compare student consumption of school meals by school level, to identify the influencing factors of school meal consumption, and to assess improvement needs of school food service among students. SUBJECTS/METHODS: A total of 1,441 elementary, middle, and high school students attending 58 schools in Gyeonggi-do, South Korea participated in the survey in 2015. A questionnaire and informed consent forms for students and legal guardians were sent home and completed responses were returned to the researcher. RESULTS: Approximately 58% of the students perceived the portion sizes of school meals as appropriate and 76.1% consumed almost all or all of the meals served. More elementary and middle school students than high school students consumed almost all or all of the meals (P < 0.001). A regression analysis revealed that the students with a higher dietary behavior score (P < 0.001), higher satisfaction with food service (P < 0.001), a higher environmental protection practice score (P < 0.05), and more positive attitudes toward school meals (P < 0.01) consumed significantly more meals. The provision of foods that taste good and reflecting student opinions on menus were the most important factors for increasing school meal consumption. CONCLUSIONS: To increase consumption of school meals, food service staff should provide students with quality meals and engage students in school food service. Nutrition education that emphasizes healthy eating behaviors and cafeteria environment modification that applies strategies based on behavioral economics can encourage students to consume more school meals.

Sexual violence, by definition, means all kinds of the physical, emotional, or linguistic violence by means of sex on which one would never agree. In a broad sense, sexual violence could include sexual assault, molestation (also referred to as sexual abuse), and sexual harassment. Sexual assault is a substitute for rape used in media reports. Rape is an coerced sexual intercourse in which a man is putting his penis inside a woman's vagina by means of an act of violence and intimidation and a heinous crime which infringe on human rights of sexual self-determination, and freedom and tranquility of sexual life. Psychologically, it is important to be aware that rape is not a sexual behavior in common sense. It should be treated as an event in which one person violate another by means of sex. Many a serious rape is liable to be committed from the impure motive of sadistic ostentation of one' power and retributive exhibition of one's anger. The criminal object of rape is women and girls. Previously, as prescribed by law, interpretation of the law restricted the object of the crime to biological and genetical female who also is not rapist's wedded wife. But, the latest judicial precedent appreciated a person who is rapist's wedded wife as the object of the crime. Considering previous judicial precedents and the tendency of juridical interpretation on the minors of transgender, even a transgender female underwent sex exchange operation could be legally appreciated as the object of the crime. So, therefore, gynecologist who would initially confront rape victim in the field of medical practice should carry out one's medical and legal obligation, irrespective of whether or not the victim would be a biological and genetical female or a rapist's wedded wife or a transgender female underwent sex exchange operation. Especially, gynecologist should not judge whether rape is committed or not only by external wound. And, even if the victim and legal guardians would not want to accuse rapist on charges of rape at the moment, gynecologist should collect all the criminal evidences just in case an accusatorial procedure would be presented later on. Successful prosecution of rapist would be dependent upon the completion of the detailed forensic examination. Because of the legal ramifications of rape, consent should be obtained from the victim before taking the history, performing the physical examination, and collecting the criminal evidence. Many rape survivors would not inform their gynecologist of the assault voluntarily, unless they are directly asked. So, therefore, on getting a medical history, gynecologist should routinely ask their patients a question, "Has anyone ever coerced you to have sexual relations?". Actually, rape is severe and complex form of trauma which could bring about an excruciating damage on physical, psychological, and sexual health and, thereupon, might have an impact on the victim for the rest of one's days.

OBJECTIVETo test and verify the regression equation got before for children's dental behavior management problems(BMP).

METHODSThe study group included 279 children aged 2- < 8 years who received dental treatment by 16 pediatric dentists in the Department of Pediatric Dentistry, Peking University School of and Hospital of Stomatology. Interviews were conducted with accompanying guardians and children's dental behavior was rated by a modified Venham's clinical anxiety scale and a cooperative behavior rating scale. The variables were put into the regression equation and the results were compared with their dental behavior scale.

RESULTSThe accuracy rate of regression equation reached 84.2% (235/279) , sensitivity was 0.613 (95%CI:0.514-0.712) and specificity was 0.957 (95%CI:0.928-0.986).

CONCLUSIONSThe regression equation is characterized by its accuracy rate at a good level. Younger age, negative guardian expectations of the child's behavior during treatment, anxiety or shyness around strangers, and presence of toothache were four risk factors for children's dental BMP.

OBJECTIVE: The progress in computer and communication technologies is making the Internet increasingly heterogeneous in terms of network, hardware and software capacities. Moreover, this has made it possible for emergency telemedicine services to provide high quality medical services. However, resource availability on the Internet varies unexpectedly. Thus, providing an efficient access to emergency telemedicine services requires that medical multimedia streams be adapted according to the environment constraints. One approach to this issue is based on the use of intermediate nodes within the network to perform such adaptations (media transformations and data transcoding). For this purpose, we have designed and implemented a proxy server for Quality of Service adaptations of medical multimedia streams. METHODS: We have organized a new emergency telemedicine system by designing a proxy server to execute transcoding. The proxy server is located between a patient system and a doctor system over heterogeneous networks. Before a patient system can deliver medical video streams to a doctor system, the proxy server measures uplink bandwidth which is one of the Quality of Service factors, from the proxy server to the doctor system. At this moment, frame rates are determined according to the measured bandwidth, and the proxy server transmits medical video streams modified for new frame rates to the doctor system. We describe the implementation of this proxy server on top of the Microsoft DirectShow(R) environment and report on a performance evaluation which demonstrates the effectiveness of the approach. RESULTS: The quality of requested medical video streams can be predicted when they are adapted to the receiver. With this prediction, adapted medical video streams which meet the frame rates constraints of the receiver can be delivered without additional measurements of bandwidth. CONCLUSION: This study represents a proxy server of a hybrid multimedia telemedicine system over heterogeneous networks. We expect that the designed proxy server can provide not only dynamic Quality of Service monitoring functions along bandwidth measurement, but also medical video adaptations to the receiver in heterogeneous network environments.

OBJECTIVES: Deficit schizophrenia (DS) constitutes a disease separate from non-deficit schizophrenia (NDS). The aim of the current study was to compare the quantitative EEG and low resolution electromagnetic tomography (LORETA) imaging between DS and NDS. METHODS: This study was performed by 32 channels EEG for 42 schizophrenia patients who we categorized into DS and NDS using proxy instrument deficit syndrome (PDS). We performed the absolute power spectral analyses for delta, theta, alpha, low beta and high beta activities. We compared power spectrum between two groups using Independent t-test. Partial correlation test was performed with clinical parameters. Standardized LORETA (sLORETA) was used for comparison of cortical activity, and statistical nonparametric mapping (SnPM) was applied for the statistical analysis. RESULTS: DS showed significantly increased delta and theta absolute power in fontal and parietal region compared with NDS (p<0.05). Power spectrum showed significant correlation with 'anergia' and 'hostility/suspiciousness' subscale of brief psychiatric rating scale (BPRS)(p<0.05). sLORETA found out the source region (anterior cingulate cortex/limbic part) that delta activity was significantly increased in DS (p=0.042). CONCLUSIONS: DS showed different cortical activity compared with NDS. Our results may suggest QEEG and LORETA could be the marker in differentiating between DS and NDS.

PURPOSE: Recent studies suggest that the symptomatic improvement in benign prostatic hyperplasia significantly related with transition zone volume (TZV). The purpose of this study was to determine the clinical significance of TZV and transition zone index (TZI) in changes of prostate volume (PV) and clinical parameters following finasteride therapy. MATERIALS AND METHODS: 140 patients over 50 years of age with symptomatic benign prostatic hyperplasia were treated with finasteride (5mg/d) for 12 months and underwent transrectal ultrasound evaluation of PV and TZV prior to initiating therapy and after 12 months. Patients were grouped according to the results of PV (> OR =40ml or <40ml), TZI (> OR =0.45 or <0.45) and PSA level (> OR =2.5 or <2.5). The responders was determined as improvement in peak flow rate more than 3mL/sec. RESULTS: PV decreased by 14.11% in patients with TZI less than 0.45, while the decrease was 19.25% for men with TZI greater than 0.45 (p<0.01). In addition, PV was significantly decreased by 16.72% in patients with PV less than 40cc and TZI greater than 0.45 (p<0.01). PV decreased by 17.37% in patients with PSA less than 2.5, while the decrease was 18.92% in men with PSA greater than 2.5. In responders, only TZI was significantly different among PSA, PV and TZI (p<0.05). CONCLUSIONS: Treatment effect of finasteride on symptomatic benign prostatic hyperplasia patients was increased in proportion to enlarged PV, increased TZI, increased PSA. TZI was a useful proxy for predicting clinical outcomes in initiating finasteride therapy on benign prostatic hyperplasia.
