Recruited from Korean-Chinese elementary schools in Shenyang and Harbin, China, 100 children living apart from their parents and experiencing non-maternal care provided information about the separation (reason and duration of parent-child separation, present location of parents, etc.), their adjustment to separation, and their perception of attachment with their caregivers. Results showed that although the separated children adjusted positively to parent-child separation in general, over 55% of them reported loneliness. Attachment with caregiver was the most significant influential variable on children's behavior problems. Duration of separation from father was related to children's hostility/aggression and hyperactivity/attention deficit problem, while duration of separation from mother influenced children's anxiety.

Objectives: This study aimed to evaluate preliminarily the clinical effects of cognitive-behavioral treatment in children with anxiety disorders. Methods: Subjects were 11 children between 2nd and 6th grade with anxiety disorder. All subjects were diagnosed through Kiddie-Schedule for Affective Disorder and Schizophrenia Present and Lifetime Version (K-SADS-PL) interview. The CBT program consisted of sessions once a week (60min/session) for 14 weeks with parent education. Results: Children and parents reported significantly improved social skills, social competence and decreased anxiety. However, there were no significant changes in children's negative thoughts and subjective depressive symptoms. Conclusion: Cognitive-behavioral treatment is expected to be effective in children with anxiety disorders such as generalized anxiety disorder, phobia, separation anxiety disorder, and obsessive-compulsive disorder.

Objective: Taking note of the fact that North Korean refugee children experience frequent separation from their mothers and long-term maternal deprivation during their childhood, this study examined the relationship between children's separation experiences and attachment. Methods: A total of 37 children aged from 5 to 9 were assessed on their attachment using the Separation Anxiety Test, and their mothers reported on their child's separation experiences. Results and Conclusion: The major findings of this study were as follows: first, the result of evaluating their attachment pattern showed North Korean refugee children had a high level of insecure attachment with a high tendency for avoidant attachment. This avoidant attachment tendency is probably due to growing up in a repressed emotional environment by frequently experiencing maternal separation in North Korea, China, and even after settling down in South Korea. Second, children's secure attachment level was higher if they did not experience separation from their mother, if their mother had a high level of education in South Korea, or if they lived with a big family.

This study was conducted to investigate the effects of covid-19 pandemic on mother's child-rearing style and provide information on mother-rearing. The significance of regression coefficients was verified to investigate the factors affecting warm parenting and control parenting, and the effect of separation and individualization on warm parenting (β=-).40, p <.001). Moreover, covid infection has a positive effect on controlled child care (β=.21, p=.002), and separation has a significant effect on controlled child care (β=-26, p<.001). Based on the results of these studies, we can see that the strong belief in mother-rearing and the separation and individualization of healthy children have a great impact on child growth.

Objective: Sex differences in attachment types are absent during early childhood, but emerge in middle childhood. Prior research has shown that boys classify as more often avoidant than ambivalent. The purpose of this study was to investigate marked sex differences in the distribution of attachment types in middle childhood, especially in boys. Methods: Attachment was assessed with the Separation Anxiety Test in a sample of 208 boys in Grades 3 and 4. Their socioeconomic backgrounds and developmental histories were also collected. Results: The distribution of attachment types was differed from those in early childhood, with insecure boys more often avoidant (31.3%) than ambivalent (7.2%). Insecure-avoidant boys were rated as over 10% compared the global distribution. Conclusion: These results supported the hypothesis of adrenarche in middle childhood. Boys may be changed to have more avoidant types in attachment.

Objectives The loss of maternal care during early postnatal period may increase development of mood-related disorders, such as depression, anxiety, and personality disorders. In this study, the effect of acupuncture on depression in relation with cell proliferation in the hippocampal gyrus dentatus was investigated using maternal-separated rat pups. Methods On the postnatal 14th day, rat pups from six dams were grouped into following groups: maternal care group, maternal separation group, maternal separation and non-acupoint-acupunctured group, maternal separation and Zusanli-acupunctured group, and maternal separation and fluoxetine-treated group. Acupuncture was performed from postnatal 28th day to postnatal 37th day. The rat pups that belong in the maternal separation and fluoxetine-treated group were injected subcutaneously with 5 mg/kg fluoxetine hydrochloride once a day for the same period of time. To evaluate activity of the rat pups, open field test was performed. Immunohistochemistry for serotonin (5-hydroxytryptamine, 5-HT) and tryptophan hydroxylase (TPH) in the dorsal raphe and for 5-bromo-2'-deoxyuridine (BrdU) in the hippocampal gyrus dentatus was conducted. Results The present results reveal that the activity was decreased by maternal separation. In contrast, acupuncture at Zusanli overcame maternal separation-induced hypoactivity. Maternal separation suppressed TPH expression and 5-HT synthesis in the dorsal raphe and decreased cell proliferation in the hippocampal gyrus dentatus of rat pups. In contrast, acupuncture at Zusanli alleviated maternal separation-induced decrease of 5-HT synthesisand TPH expression. Conclusions The present results demonstrate that acupuncture at Zusanli ameliorated depressive state through increasing cell proliferation and enhancing 5-HT synthesis.

The study presented the experience of playtherapy of a 6-yr old girl with elective mutism and attempted to understand her psychopathology and formulated her psychodynamic which was expressed though the therapeutic process of playtherapy in the viewpoint of developmental model. Therapist's attitude was nondirective and supportive. Main theme of her play, fantasy and art was separation anxiety and abandonment fear as the result of continued psychic traumas such as separation from her grandmother and physical abuse by her father and mother etc. So she couldn't achieve developmental tasks such as autonomy and separation individuation and became generally inhibited and selectively mute. The process of play therapy was summarized and coceptualized as her successful progress through sequential developmental phases within the therapeutic relation ship. By reexperiencing this developmental process, she could accomplish her autonomy and separation individuation and developed to oedipal stage and successfully resolve oedipal conflict.

With the recent development of sleep medicine, insomnia has been perceived as a disease from a simple symptom. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment In general, insomnia is classified into five categrories of physical, physiological, psychological, psychiatric and pharmacological aspects. However, such categorizations are often insufficient in treating insomnia. Furthermore understanding of the developmental mechanisms of insomnia is required. The function of sleep is developed and maintained through the balance of the reciprocal forces of sleep and arousal. These forces are contantly regulated by what is called a circadian rhythm. Sleep is induced by this rhythm which is affected by factors such as awakening time in the morning, amount of intellectual function, amount and time length of physical exercise and sunlight Insomnia could develop when this rhythm is delayed and leads to a "forbidden zone" which is a very difficult period for inducing sleep about two to four hours before the routine bedtime. Whereas sleep gradually develops in line with the circardian rhythm, arousal can occur very abruptly by any cause triggered by emotional discomfort or anxiety. Such characteristic and emotional factors as perfectionism, separation anxiety, secondary gain, insecurity, and negative cognition may provoke the inner anxiety and fear for insomnia, which can lead acute insomnia to a chronic one. As chronic insomnia is developed by multiple causes and factors, integrated approaches through analysis of above mentioned factors will be more effective in the treatment of insomnia than a simple administration of hypnotics.

Electroencephalography (EEG) measures neural activation due to various cognitive processes. EEG and event-related potentials (ERPs) are widely used in studies investigating psychopathology and neural substrates of psychiatric diseases in children and adolescents. The present study aimed to review recent ERP studies in child and adolescent psychiatry. ERPs are non-invasive methods for studying synaptic functions in the brain. ERP might be a candidate biomarker in child-adolescent psychiatry, considering its ability to reflect cognitive and behavioral functions in humans. For the EEG study of psychiatric diseases in children and adolescents, several ERP components have been used, such as mismatch negativity, P300, error-related negativity (ERN), and reward positivity (RewP). Regarding executive functions and inhibition in patients with attention-deficit/hyperactivity disorder (ADHD), P300 latency, and ERN were significantly different in patients with ADHD compared to those in the healthy population. ERN showed meaningful changes in patients with anxiety disorders, such as generalized anxiety disorder, separation anxiety disorder, and obsessive-compulsive disorder. Patients with depression showed significantly attenuated RewP compared to the healthy population, which was related to the symptoms of anhedonia.
