OBJECTIVES: The purpose of this study is to get basic data to develop plan and strategy of com-munity mental health in Pohang city by identifying attitudes toward mentally ill in Pohang community. METHODS: The subjects of this study are the 491 persons aged between 20 and 59 who live in Pohang. Methods of selection for the subjects based on multistage stratified cluster sampling, i.e. by sex, by age, by place of residence("Up", "Myeon", "Dong"), and by ratio to total populations. Tool of the study is Community Attitudes to the Mentally Ill Inventory(CAMI). RESULTS: 1) The residents of Pohang community showed positive attitude in 'Benevolence' and 'Community mental health ideology' subscale and negative attitude in 'Authoritarianism' and 'Social restric-tiveness' subscale. Therefore community mental health project in Pohang city will be established and activated easily. 2) Aged group had more authoritative, social restrictive and less community mental health oriented attitude. 3) The lower educated group had more authoritative, social restrictive and less benevolent, community mental health oriented attitude. 4) The unmarried group had less authoritative, less social restrictive attitude. 5) The home-owners had more authoritative, more social restrictive attitude. 6) The opinion leaders had more authoritative and less community mental health oriented attitude. 7) The respondents whose family had used mental health services had less benevolent attitude. The respondents who themselves had used mental health services had more authoritative, less benevolent and community mental health oriented attitude. CONCLUSIONS: Therefore, it will be necessary to give public information and education for those who have negative attitude groups of aged, low educated, home-owners, opinion leaders and respondents who themselves or whose family had used mental health services. If resource could be made of persons of positive attitude groups of younger aged, highly educated and unmarried, community mental health project will be more efficient.

The neurobiological basis of emotional recognition, processing and regulation has been extensively studied over the past years. Especially, posttraumatic stress disorder (PTSD) can be conceptualized as a dysfunction of fear circuit, thus, many studies focused on neural substrate of fear using functional neuroimaging. Neuroimaging studies of PTSD have suggested that the amygdala is hyperresponsive to fearful stimuli, which may be related to hyperarousal or reexperience symptoms of PTSD. The medial prefrontal cortex is hyporesponsive and fails to inhibit the amygdala. Researches also have acknowledged that abnormal activities in ventromedial prefrontal cortex and hippocampus might be associated with impairment of extinction of traumatic memory. Recent researches using facial emotional stimuli have suggested that PTSD involved not only dysfunction of fear circuit but also dysregulation of basic emotional processing. Despite the progress, many points are left which are yet to be clarified. Fear conditioning, contextualization, habituation and extinction should be investigated using novel paradigms that can explain the complexity of PTSD.

OBJECTIVE: Transcranial magnetic stimulation (TMS) is a new, noninvasive procedure of a localized pulsed magnetic field to the surface of the head to cause a depolarization of neurons in the brain cortex underneath. Knowledge of the neuroanatomic abnormalities of depression is serving as the background for TMS treatment in depression. Here we provide a summarized review of the therapeutic application of TMS in patients with depression. METHODS: We described the clinical and basic researches of TMS in depression and integrated the future direction using literature review and interview with experts. RESULTS: The field of TMS is beginning to address the issues of using TMS as a novel antidepressant. The ability to excite local areas of brain cortex has raised the possibility of the use of TMS as a novel therapeutic tool for depression. CONCLUSIONS: Many parameters, such as intensity, location, frequency, pulse width, intertrain interval, coil type, duration, numbers of sessions, and interval between sessions remain to be systematically explored. However TMS would be a relatively new and noninvasive method to investigate regional brain activity and to treat depression.

Objective:
To identify, for the first time, the prevalence and impact of Boosepivirus (BooV) on calf diarrhea in the ROK.
Methods:
Here, the unknown cause of calf diarrhea was determined using metagenomics We then explored the prevalence of certain pathogens, including BooV, that cause NCD. Seventy diarrheal fecal samples from Hanwoo (Bos taurus coreanae) calves were analyzed using reverse transcriptase and quantitative real-time polymerase chain reaction for pathogen detection and BooV isolate sequencing.
Results:
The complete genome of BooV was detected from unknown causes of calf diarrhea.And also, BooV was the most frequently detected pathogen (35.7%) among 8 pathogens in 70 diarrheic feces from Hanwoo calves. Co-infection analyses indicated that most BooV-positive samples were solely infected with BooV, indicating its significance in NCD in the ROK. All isolates were classified as BooV B in phylogenetic analysis.
Conclusions
and Relevance: This is the first study to determine the prevalence and molecular characteristics of BooV in calf diarrhea in the ROK, highlighting the potential importance of BooV as a causative agent of calf diarrhea and highlighting the need for further research on its epidemiology and pathogenicity.

8.Update on the Evidence Regarding Maintenance Therapy.
Tuberculosis and Respiratory Diseases 2014;76(1):1-7
Maintenance therapy has emerged as a novel therapeutic paradigm for advanced non-small-cell lung cancer (NSCLC). Maintenance therapy that aims to sustain a clinically favorable state after first-line chemotherapy has two strategies. Switch maintenance therapy entails switching to a new and non-cross-resistant agent in an alternating or sequential manner, on completion of first-line chemotherapy. Continuous maintenance therapy keeps ongoing administration of a component of the current regimen after four to six cycles of chemotherapy, if there is a stable disease, or better response. Both maintenance therapies can be continued, until disease progression. The potential evidence regarding maintenance therapy includes providing the opportunity to receive additional treatment, through sustaining tumor shrinkage, and delayed emergence of tumor-related symptom. Thus far, debates over the parameters used to predict the effectiveness of maintenance therapy, financial burden, and uncertainty of improving the quality of life exist. Despite many debates, maintenance therapy, which is currently recommended, has been disclosed to be beneficial.

PURPOSE: Although there have been studies emphasizing the re-education of North Korean (NK) doctors for post-unification of the Korean Peninsula, study on the content and scope of such re-education has yet to be conducted. Researchers intended to set the content and scope of re-education by a comparative analysis for the scores of the preliminary examination, which is comparable to the Korean Medical Licensing Examination (KMLE). METHODS: The scores of the first and second preliminary exams were analyzed by subject using the Wilcoxon signed rank test. The passing status of the group of NK doctors for KMLE in recent 3 years were investigated. The multiple-choice-question (MCQ) items of which difficulty indexes of NK doctors were lower than those of South Korean (SK) medical students by two times of the standard deviation of the scores of SK medical students were selected to investigate the relevant reasons. RESULTS: The average scores of nearly all subjects were improved in the second exam compared with the first exam. The passing rate of the group of NK doctors was 75%. The number of MCQ items of which difficulty indexes of NK doctors were lower than those of SK medical students was 51 (6.38%). NK doctors' lack of understandings for Diagnostic Techniques and Procedures, Therapeutics, Prenatal Care, and Managed Care Programs was suggested as the possible reason CONCLUSION: The education of integrated courses focusing on Diagnostic Techniques and Procedures and Therapeutics, and apprenticeship-style training for clinical practice of core subjects are needed. Special lectures on the Preventive Medicine are likely to be required also.

OBJECTIVE: Weight gain is a commonly encountered problem associated with atypical antipsychotics, especially olanzapine. To investigate the weight reducing effect of amantadine, we conducted an prospective open label study. METHODS: We started amantadine treatment in outpatients who had gained weight during olanzapine treatment (mean dose of 11.94 mg/day, mean weight gain of 6.33 kg). Data were collected at St. Mary's Hospital, College of Medicine, The Catholic University of Korea. The add-on treatment of amantadine was given at a mean dose of 161.9 mg/day with mean duration of administration for 110.2 day. Brief Psychiatric Rating Scale (BPRS), Extrapyramidal Symptom Scale were checked to evaluate the tolerability of amantadine. RESULTS: Before administration of amantadine, the mean dose of olanzapine was 11.94+/-4.58 mg and mean duration of administration was 123.1+/-174.6 days. Body weight and BMI during this period was significantly increased mean 6.33+/-4.45 kg (Z=-3.839, p<0.001), 4.94+/-0.75 (Z=-3.724, p<0.001) respectively. Amantadine was administered mean dose of 161.90+/-58.96 mg for mean 110.2+/-78.7 days. Body weight and BMI was decreased mean 0.96+/-3.44 kg, 0.71+/-2.7, respectively. There was no deterioration in psychiatric symptoms, as shown in BPRS score decrement and no adverse effects were reported. CONCLUSION: The present data suggests that amantadine does not significantly decrease weight gain experienced by some patients during olanzapine treatment and does not worse psychotic symptoms. Randomized placebo-controlled trial should be needed to confirm these findings.
