Objectives : Increasing evidence supports the biological and pharmacological activities of essential oils on the central nervous system such as pain, anxiety, attention, arousal, relaxation, sedation and learning and memory. The purpose of present work is to investigate the protective effect and molecular mechanism of cypress essential oil (CEO) against scopolamine (SCO)-induced cognitive impairments in C57BL/6 mice. Methods : A series of behavior tests such as Morris water maze, passive avoidance, and fear conditioning tests were conducted to monitor learning and memory functions. Immunoblotting and RT-PCR were also performed in the hippocampal tissue to determine the underlying mechanism of CEO. Results : SCO induced cognitive impairments as assessed by decreased step-through latency in passive avoidance test, relatively low freezing time in fear conditioning test, and increased time spent to find the hidden platform in Morris water maze test. Conversely, CEO inhalation significantly reversed the SCO-induced cognitive impairments in C57BL/6 mice comparable to control levels. To elucidate the molecular mechanisms of memory enhancing effect of CEO we have examined the expression of brain-derived neurotrophic factor (BDNF) in the hippocampus. CEO effectively elevated the protein as well as mRNA expression of BDNF via activation of cAMP response element binding protein (CREB). Conclusions : Our findings suggest that CEO inhalation effectively restored the SCO-impaired cognitive functions in C56BL/6 mice. This learning and memory enhancing effect of CEO was partly mediated by up-regulation of BDNF via activation of CREB.

Objectives : This study investigated the differences of working memory among the subtypes of ADHD. Methods : Eighty-one children and adolescents with ADHD and thirty normal controls were recruited. Children with any cognitive disorders and low intelligence were excluded. In order to evaluate the verbal and visuospatial working memory, Digit span and Finger windows tasks were measured, respectively. Performances on these measures between children with ADHD and controls were compared. Further, performances among the groups of ADHD predominantly inattentive(ADHD-IA)(n=40), predominantly hyperactive-impulsive(ADHD-HI)(n= 10), and combined type(ADHD-C)(n=31), were compared. Results : Scores of Finger windows forward task were lower in the ADHD group as compared to the control group, whereas, the Digit span forward showed no difference. Both scores of Digit span backward and Finger windows backward task were lower in the ADHD group than the controls. Children with ADHD-IA performed poorer than children with ADHD-C on the Finger windows backward task. Conclusion : The results of this study showed that children with ADHD have deficits in spatial short-term memory and verbal and visuospatial working memory when compared to normal children. The deficits were evident in children with ADHD-IA subtype and in particular, performance on the visuospatial working memory task in this group was poorer than the ADHD-C group.

Purpose: This study was done to provide support material to traditional nursing interventions through investigation of the effect of Auricular acupressure therapy for female staff in the hospital who have dysmenorrhea but cannot be absent from work even with severe symptoms affecting their work and therefore cannot get proper pain management. Method: The participants in this study were 62 women were working in the G-university hospital in Jin-ju, assigned to experimental (30) and 32 control groups (32). The study method was a quasi-experimental, nonequivalent control group non-synchronized design. The experimental group received acupressure treatment (a pin was attached to tape) on the special stimulation points in the inside of the ear, 5 times for 5 seconds, morning, afternoon, and night. Tape without the pressure pin was applied to the same points for women in the control group to evaluate placebo effect. Data were collected from May to November 2007 and were analyzed using SPSS PC+ 12 version. Descriptive statistics, t-test, $x^2-test$, Fisher's exact test, paired t-test, were used to analyze the data. Results: The experimental group showed a significant decrease in dysmenorrhea compared to the control group (t=-2.743, p<.01). In the sub-part, the experimental group showed menstruation related pain (t=-3.726, p<.01), menstruation related to behavioral change (t=-2.421, p<.05) and symptoms however, there was no significant difference related to attention deficit, water retention, and negative image. Conclusion: Application of auricular acupressure therapy was approved for this study and although auricular acupressure therapy was not effective for all of the symptoms, it was effective for dysmenorrhea.

Objectives : The purpose of this study was to investigate changes in child and adolescent outpatients at a university hospital in Daegu from 2004 to 2013. Methods : The subjects were first-visit patients under 18 years old, who visited Dongsan Medical Center, Keimyung University, from January 1, 2004 to December 31, 2013. Computerized medical records of 2,738 patients (male 1,906, female 832) were reviewed. Results : The ratio of male to female was 2.3 : 1 in the period of study. The most prevalent age category was 7-9 years. The mean age was $10.12{\pm}4.68$ years ($9.84{\pm}4.59$ years in males, $10.76{\pm}4.81$ years in females). The ratio of child and adolescent patients to total outpatients was 27.0%. The most common diagnostic category was the attention-deficit hyperactivity disorder (ADHD) group, followed by the mental retardation (MR) group. In males, the ADHD, MR, communication disorder groups were more prevalent, but in females, the MR, ADHD, depressive disorder groups were more prevalent. Conclusion : The female to male ratio and total mean age were on the rise. The ADHD group was the most prevalent and the depressive disorder group was also on the rise in this period.

Objectives : This study was conducted to compare the object relations and parenting behavior of the mothers of children with attention-deficit hyperactivity disorder (ADHD) with that of the mothers with normal children. Methods : In this study, we studied 64 mothers of children who were diagnosed with ADHD and 90 mothers of normal children. The mothers completed the Bell Object Relations Inventory (BORI), the Parenting Behavior Inventory (PBI), the Parenting Stress Index (PSI) and the Parenting Sense of Competence (PSOC) scale. Results : As compared with the mothers of normal children, the mothers of children with ADHD showed significantly different results for the parenting stress and parenting efficacy. For parenting behavior, the mothers of children with ADHD perceived their mothering as being more neglectful. On the other hand, the mothers of the normal control group perceived their mothering as being more affectionate and the fathers as being more reasonable and monitoring. Conclusion : This study suggests there is a significant difference of object relation between the mothers of children with ADHD and the mothers with normal children. The object relation pathology of the mothers of children with ADHD might contribute to impaired parenting behavior. The result of the present study indicate that inadequate grandparental rearing behavior affects the insecure object relation of their child (the mother), and a mother's insecure object relation affects their parental stress and parenting efficacy.

Objectives ： This study aimed to examine the association between norepinephrine transporter gene (SLC6A2) polymorphisms and attention-deficit hyperactivity disorder (ADHD) and to examine the relationship between the genotypes and allele variants of SLC6A2 and results of the Korean version of the parent ADHD rating scale (K-ARS). Methods ： We examined the association between ADHD and norepinephrine transporter gene polymorphism using DNA from 137 Korean children with ADHD and 120 normal controls. We compared the genotype distributions and allele frequencies of SLC6A2 polymorphism between the control group and the ADHD group. Then, we correlated the children's K-ARS mean totals, inattention scores, and hyperactivity/impulsivity scores with the genotypes and alleles for each SLC6A2 polymorphism. Results ： There were no significant differences in genotype and allele distribution for each SLC6A2 polymorphism, as shown by the Chi-square test (p>.01). There was a trend toward a difference in allele frequency in rs 5568, but it was not statistically significant after adjusting for multiple comparisons (p=.048). Also, there were no significant differences in K-ARS scores according to the genotypes and alleles for the SLC6A2 polymorphisms. Conclusion ： Our study found no significant evidence of an association between SLC6A2 polymorphisms and ADHD.
