The purpose of this study was to examine the relations of matemal parenting behaviors, child's stranger anxiety, and separation anxiety to matemal separation anxiety. A total of 288 middle class mothers having children aged from 36- to 59-month- olds answered to a questionnaire based on Maternal Separation Anxiety Scale (Hock, 1989). They also answered the questions about maternal parenting behaviors, child's stranger anxiety, and separation anxiety. The main results were as follows : 1. There were no significant differences in maternal separation anxiety as a function of demographic variables. 2. Maternal parenting behaviors such as physical contact and discipline involvement were significantly related to maternal separation anxiety. And child's stranger anxiety and separation anxiety were also significantly related to matemal separation anxiety. 3. Maternal separation anxiety was accounted for 15% of the variance by maternal physical contact, discipline involvement, and chlid's stranger anxiety and separation anxiety.

The purpose of this study was to examine the relations between mothers's and children's characteristics, maternal separation anxiety, and overprotective parenting with a sample of 212 mothers of 3-6 year-old children. The subjects reported maternal separation anxiety, children's initial temperament, their own experience in the childhood and personality, and overprotectiveness. The results indicated that 1) mothers who experienced higher parental acceptance showed higher maternal separation anxiety; 2) mothers who perceived that their children had avoidant temperament showed higher material separation anxiety; 3) mothers who showed higher separation anxiety reported higher overprotectiveness; 4) maternal separation anxiety played a mediating role in the relations between children's approach-avoidance temperament and mothers' sheltering behavior.

The purpose of this study was the development of a scale to assess maternal anxiety after mother-child separation. Subjects consisted of 384 mothers who had children from 6 to .36 months of age. A questionnaire consisting of eighty Likert-type items and Spielberger's(1970) State Anxiety Scale were administered to mothers and data were analyzed using item analysis. factor analysis. multiple regression. Cronbach's ${\alpha}$. Pearson's correlation and F-test. Sixty of the eighty items were significant and deemed acceptible through item discrimination method with indices ranging from. 32 to .95. Factor analytic procedures have selected 54 items of the 60-item scale and supported a 5-factor solution. The subscales labeled 'Maternal Separation Anxiety'. 'Perception of Separation Effects on the Child', 'Desire for Physical Cuddling and Closeness'. 'Attitudes toward the Value or Importance of Exclusive Maternal Care' and 'Employment-related Separation Concerns,' Finally. a multiple regression analysis conducted to reduce the length of the scale yielded a 39-item form for the Maternal Separation Anxiety Scale(MSAS). Internal consistency of the MSAS was high(Cronbach's ${\alpha}$ =.85). The correlation of the MSAS with the Spielberger's State Anxiety measure yielded a coefficient of .36, revealing a moderate and positive relationship.

Ketamine has long been used as an anesthetic agent. However, ketamine use is associated with numerous side effects, including flashbacks, amnesia, delirium, and aggressive or violent behavior. Ketamine has also been abused as a cocktail with ecstasy, cocaine, and methamphetamine. Several studies have investigated therapeutic applications of ketamine, demonstrating its antidepressant and anxiolytic effects in both humans and rodents. We recently reported that neonatal maternal separation causes enhanced anxiety- and aggressive-like behaviors in adolescent. In the present study, we evaluated how acute and chronic ketamine administration affected the behavioral consequences of neonatal maternal separation in adolescent mice. Litters were separated from dams for 4 hours per day for 19 days beginning after weaning. Upon reaching adolescence (post-natal day 35-49), mice were acutely (single injection) or chronically (7 daily injections) treated with a sub-anesthetic dose (15 mg/kg) of ketamine. At least 1 h after administration of ketamine, mice were subjected to open-field, elevated-plus maze, and resident-intruder tests. We found that acute ketamine treatment reduced locomotor activity. In contrast, chronic ketamine treatment decreased anxiety, as evidenced by increased time spent on open arms in the elevated-plus maze, and remarkably reduced the number and duration of attacks. In conclusion, the present study suggests that ketamine has potential for the treatment of anxiety and aggressive or violent behaviors.

The purpose of this study was to find out the characteristics of foster care of long-distance parents who meet their children on weekend and to examine the relationships among the separation anxiety and maternal guilt in foster care. The subject consisted of 138 employed mothers who are living separately with their children. The instruments used for this study were the Separation Anxiety Scale(Cho & Park,1992), the Maternal Guilt Scale(Kim & Kang, 1997), the Parental Satisfaction Scale(Hyun & Cho,1994), and the Parental Stress Scale(Park,1994). The main results of this study were as followings: 1. Mothers had a tend to rely on family members expecially grandparents for foster care of their children. They usually have visited to meet their children weekend and made a phone call once a day. Parental satisfaction in foster care was reported to be moderately high level. 2. The subject’s separation anxiety was found to be high, and it was strong positive relationships to maternal guilt feeling in foster care. The results of this study have implications for both formal and informal support systems of employed mothers with children. The findings of this study may used as basis for understanding long-distance parents’problems in foster care, developing support programs, and public policy for employed mothers.

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 purpose of this study is to analyse how the separation anxiety of mothers and children influences on the children's peer competence through mother's overprotection. The subjects of this study were 302 children and their mothers, three to five years old who attended at educare centers and kindergartens which were located in Cheongju city and Daejeon city. The results of this research were as follows: First, there were differences in the separation anxiety of mothers and children, maternal overprotective behavior, and children's peer competence according to the social demographic backgrounds. Second, the separation anxiety of mothers and children influenced on mother's sheltering behavior and babying behavior. Third, mothers' sheltering behavior mediated the relationship between mothers' and children's separation anxiety and children's prosocial behavior. It also appeared that mothers' babying behavior mediated the relationship between the separation anxiety of mothers and children and children's initiative.

The relationship of maternal separation anxiety, availability of support system and child gender to initial preschool adjustment was examined. Data were collected on 72 middle-class Korean children(35 boys, 37 girls) between the ages of 31 months and 60 months who were entering preschool. Subjects were from intact families, all with non-working mothers. Mothers completed the Maternal Separation Anxiety Scale(MSAS) and indicated the number of extended family members in the home as an index of social support. Classroom teachers completed the Preschool Behavior Questionnaire (PBQ) for each child after the first 2 weeks and again after 6 weeks of school. Each child was observed by the research team during the first 2 weeks of school and again after the 6th-week using the Child Observation System (COS). Applying the COS observed behavior was classified as being in the dependent, neutral, or active mode. All instruments were culturally relevant as validated by Korean experts. Maternal Separation Anxiety was a significant predictor for girls only, accounting for 11% of initial COS variance (p=＜.05). In contrast, social support was a significant predictor for boys only, accounting for 28% of initial PBQ variance when entered after MSAS(p=.005). A significant difference between initial and 6th-week adjustment was obtained in the expected direction on the COS with behavior improving with time (t=-4.06, p=.001). Although a significant difference between initial and 6th-week PBQ adjustment was also obtained (t=-3.63, p=.001), it was not in the direction expected, problematic behavior were found to increase with time. Cultural and developmental factors help explain the findings. Given the patrilineal social system in Korea, boys are highly preferred over girls. Thus the at-home support system, comprised primarily of grandparents, may have a significant influence on school adjustment particularly of first-born sons. In contrast, since girls are viewed as fragile and vulnerable, mothers may express greater separation anxiety about girls. Finally, as would be expected, older children may be able to develop coping skills more readily than younger ones, as child adjustment on the COS significanlty improved over the 6-week period.
