Resilience refers to a person's ability to successfully adapt to acute stress, trauma or more chronic forms of adversity, maintaining psychological well-being. Recent years have seen a lot of research into the neurobiological factors and mechanism that characterize resilient individuals. It has shown that resilience is mediated by adaptive changes in several neural circuits involving numerous neurotransmitter and molecular pathways. Much more study is required to achieve a deeper understanding the genetic, biological, and psychological underpinnings of resilience, as well as the interactions between these factors.

Human aggression is an urgent social and clinical problem. Aggression is an inescapable clinical challenge in diverse neuropsychiatric patients populations. Beacuse aggressive or violent behavior has many different causes and manifestations, the study of aggressive or violent behavior is very difficult. However, over the past 30years, such experiments have yields a large amount of information on the neuroanatomical, biochemical, and physiological mechanisms underlying aggression in mammals. In this paper, we reviewed the neurochemical and neuroanatomical aspects of human aggression.

Depression is a complicated psychiatric illness with severe consequences. Despite recent advanced achievements of molecular neurobiology, pathophysiology of depression has not been well elucidated. Among new findings of pathophysiology of depression, the possible fast antidepressant effect by N-methyl-D-asparate receptor antagonist, such as ketamine, is regarded as a promising treatment target of depression. Ketamine stimulates the mammalian target of rapamycin (mTOR) signaling pathway and activation of mTOR signaling pathway may be a key mechanism of the antidepressant effect of ketamine. Thus, this review describes the role of mTOR signaling in the pathophysiology of depression and developing a new treatment target of depression.

With the structural and functional neuroimaging studies on alcohol use disorders, the neurobiology of alcohol use disorder can now be directly measured in vivo. This article reviews the findings of structural and functional neuroimaging studies related to alcohol use disorder. Issues about intoxication, dependence, withdrawal, abstinence, organic change induced by chronic alcohol use, neurochemistry and craving are discussed and its clinical implications and future direction of neuroimaging studies are also suggested.

A large proportion of patients with schizophrenia show a poor response to first-line antipsychotic drugs, which is termed treatment-resistant schizophrenia. Previous studies found that a different neurobiology might underlie treatment-resistant schizophrenia, which necessitates the development of different therapeutic approaches for treating treatment-resistant schizophrenia. This study reviewed previous studies on the pathophysiology of treatment-resistant schizophrenia and the pharmacological intervention, and forthcoming investigations of treatment-resistant schizophrenia are suggested.

Stress and trauma research has traditionally focused on negative sequelae of adversity. Recently, research has begun to focus on positive outcomes, specifically post-traumatic growth (PTG) - "positive change experienced as a result of the struggle with trauma" - which emphasizes the transformative potential of one's experiences with highly stressful events and circumstances. This article describes the concept of PTG at three different perspectives. In addition we reviewed the neurobiological factors and mechanism of PTG. It has shown that PTG is mediated by adaptive changes in several neural circuits involving numerous neurotransmitter and molecular pathways. Much more study is required to achieve a deeper understanding the biological and psychological underpinnings of PTG, as well as the interactions between these factors. After all, the clinical phenomenology of PTG is very important for mental growth after trauma. The findings of this article provide further directions for research and clinical implication of PTG.

There have been considerable advances in our understanding of the neurobiology and the treatment of obsessive-compulsive disorder (OCD). However, it seems that many patients with OCD are not met with proper treatment, and even the patients who receive sufficient therapy the response rate is not high. This paper reviews the pharmacological treatments of OCD with special focus on therapeutic options for treatment resistance cases. In treating a resistant case, the clinical characteristics including comorbid conditions of the patient should be reevaluated. Through until recently, there has been no standarized guideline to treat resistance cases and much is up to clinician's preference, but thoughtful selection and combination of drugs with optimized psychosocial approach may improve the response rate. We propose an integrative therapy model for treatment resistant OCD to emphasize the need for the expansion of treatment resources. Treatment resistant OCD deserves more clinical and socioeconomic attentions and needs further research for management.

Alcohol dependence (AD) is a chronically relapsing disease and has various biological etiologies. Neither genetics nor neurobiology explains the pathogenesis of AD exclusively. AD is a multifactorial disease. This article reviews the genetic and biological aspects of AD. Many candidate genes and neurotransmitters play important roles in AD. Further studies are needed to elucidate the biological mechanisms of AD. Also the treatment of AD should be individualized according to the patients's biological characteristics.

Phenomenology was founded in the 19th century by Edmund Husserl. Apart from natural sciences and metaphysics, phenomenology is presented as a rigorous scientific discipline, which aims to provide an understanding of the subjective experiences of human beings. After the eras of descriptive and dynamic psychiatry, phenomenological methods were adopted by psychiatry, and phenomenological psychopathology suggested a new perspective for understanding the pathological experiences of psychiatric patients. However, after the development of psychopharmacology and the operational diagnostic system, the center of phenomenology in psychopathology was moved from comprehensive understanding to simple description. Thus, phenomenological psychopathology in its original meaning did not get remarkable repercussions, especially in the English-speaking world. In this article, some major concepts of phenomenology will be briefly presented and then phenomenological psychopathology in its original meaning will be introduced. Secondly, as an example of its application, symptoms of schizophrenia will be interpreted in terms of phenomenological psychopathology. Finally, the authors will present a neurobiological interpretation of the phenomenological psychopathology of schizophrenia and suggest a possible role of phenomenological psychopathology in mitigating the impasse in psychiatric genetics research.
