Objectives: This study was to develop a measurement scale that explains aggressive regulation behavior of middle school student, based on Ajzen's Theory of Planned Behavior (TPB) and verify its validity and reliability. Methods: The basic items were modified by selecting 41 items of middle school student aggressive behavior measurement scale. Through the content validity test, 63 first preliminary question items and 42 second preliminary question items were developed. The participants were 286 middle school students. The collected data were analyzed using content validity, correlation coefficient, exploratory factor analysis, confirmatory factor analysis, reliability and Cronbach α. Results: In this study, it was proved that the most important variable showing aggressive regulation behavior was aggressive regulation intention. This study was composed of 4 factors for direct measurement(attitude toward the behavior, subjective norm, perceived behavioral control, behavior intention) and 5 factors for indirect measurement(behavioral beliefs, outcome evaluation, normative beliefs, motivation to comply, control beliefs). The total variance was 65.4% and 67.6%, respectively, and the reliability was .90, .82. Finally, 42 questions were developed. Conclusion: We found the questionnaire used in this study was valid and reliable as a measure scale to explain the aggressive regulation behavior of middle school student based on TPB. Therefore, it is concluded that the aggressive regulation behavior scale could be a useful scale for the measurement of the aggressive regulation behavior of middle school student.

Background: This study evaluated the efficacy of three intraoral topical anesthetics in reducing the injection needle prick pain from local anesthetic among children aged 7-11 years old. Methods: It is a prospective, Interventional, parallel design, single-blind, randomized clinical trial in which subjects (n=90) aged 7-11 years were included in the study based on an inclusion criteria. Subjects were divided into three groups based on computer-generated randomization with an allocation ratio of 1:1:1. Groups A, B, and C received benzocaine 20% jelly (Mucopain gel, ICPA health products Ltd, Ankleshwar, India), cetacaine anesthetic liquid (Cetylite Industries, Inc, Pennsauken, NJ), and EMLA cream (2% AstraZeneca UK Ltd, Luton, UK), respectively, according to manufacturer's instructions, for 1 minute prior to local anesthetic injection. After application of topical anesthetic agent, for all the groups, baseline pre-operative (prior to topical anesthetic administration) and post-operative scores (after local anesthetic administration) of pulse rate was recorded using Pulse oximeter (Gibson, Fingertip Pulse Oximeter, MD300C29, Beijing Choice Electronic). Peri-operative (i.e., during the administration of local anesthesia) scores were recorded using Face, Legs, Activity, Cry, Consolability (FLACC) Scale, Modified Children hospital of Eastern Ontario Pain Scale (CPS) behavior rating scale, and Faces Pain Scale (FPS-R) - Revised (For self-reported pain). Direct self-reported and physiological measures were ascertained using FPS-R - Revised and Pulse oximeter, respectively, whereas CPS and FLACC scales assessed behavioral measures. To test the mean difference between the three groups, a one way ANOVA with post hoc tests was used. For statistical significance, a two-tailed probability value of P < 0.05 was considered as significant. Results: The Cetacaine group had significantly lower pain scores for self-report (P < 0.001), behavioral, and physiological measures (P < 0.001) than the other two groups. However, there was no significant difference between the Benzocaine group and EMLA group during palatal injection prick. Conclusion: Cetacaine can be considered as an effective topical anesthetic agent compared to benzocaine 20% jelly (Mucopain gel) and EMLA cream.

본 연구의 목적은 휨과 전단에 지배 받는 철근콘크리트 보에서 아치작용에 의한 전단기여분을 평가하는 모델을 개발하는 것이다. 전단력은 휨모멘트의 변화률이라는 관계식을 기초로, 분산트러스 이상화 기법을 이용하여 횡단면에서 베르누이(Bernoulli) 휨 평면으로부터 전단변형적합조건을 새롭게 유도하였다. MCFT와 분산트러스 이상화를 통해 전단흐름에 의한 복부전단요소의 전단곡률을 일치시키는 전단변형적합조건을 수립하였다. 전단변형적합조건을 이용하면, 보 전단거동은 타이드아치작용과 보 작용의 두 성분으로 수치적 분해 될 수 있다. 그리고 두 기본 작용의 분해가 가능하기 때문에 전단에 지배받는 보의 내력을 예측할 수 있다. 제안 모델의 유효성은 기존 문헌에 수록된 활용 가능한 실험 자료를 통해 검증하였고, 수행 결과는 예측치와 실험치 사이에서 실질적으로 일치하는 결과를 얻었다. 결과의 정확성으로부터 제안 모델의 합리성을 확신할 수 있었다.

Objectives We aimed to identify the neuroimaging marker for prediction of the use of atypical antipsychotics (AAP) in dementia patients. Methods From April 2010 to March 2013, 31 patients who were diagnosed as dementia at the psychiatric department of Soonchunhyang University Hospital, completed the brain magnetic resonance imaging scan and cognitive test for dementia. Ten patients were treated with AAP for the improvement of behavioral and psychological symptoms of dementia (BPSD) and the other 21patients were not. Using T1 weighted and Fluid Attenuated Inversion Recovery (FLAIR) images of brain, areas of white matter (WM), gray matter (GM), cerebrospinal fluid (CSF) and white matter hyperintensities (WMH) have been segmented and measured. Multivariate logistic regression models were applied for assessment of association between AAP use and the GM/WM ratio, the WMH/whole brain (GM + WM + CSF) ratio. Results There was a significant association between AAP use and the GM/WM ratio (odds ratio, OR = 1.18, 95% confidence interval, CI 1.01-1.38, p = 0.037), while there was no association between AAP use and the WMH/whole brain ratio (OR = 0.82, 95% CI 0.27-2.48, p = 0.73). Conclusions The GM/WM ratio could be a biological marker for the prediction of AAP use and BPSD in patients with dementia. It was more likely to increase as dementia progress since atrophy of WM was more prominent than that of GM over aging.

We interviewed and surveyed parents of 3 to 6-year-old boys in order to determine designs for indoor apparel that appealed to toddlers. In addition, on the basis of the behavioral characteristics of such boys, improvements in the development of indoor apparels were suggested. Parents preferred indoor apparels because it could be worn as underwear when the kid is outdoors and as outerwear when indoors. These apparels were popular with toddlers. Therefore, indoor apparel that gives the impression of outerwear while performing the function of underwear was designed. Underwear fabric was used, but outerwear apparel design was partially adopted. In order to improve the activity, fabric that could be stretched in any direction was used for the sleeves and pant legs, while organic fabric with soft texture was used for the trunk part of the apparel. Dark-colored material was used for the chest and elbow parts of the clothes in order to prevent contamination in these parts. In particular, a bib was used to prevent contamination in the chest part. Given that toddlers engage in many activities, the fabric needed to be durable, so this led to thick materials being used for the knee part. As certain parents complained about the short length for tops, we increased the length of the tops by 5cm. In the survey items that investigated overall wearability, ease, and suitability for toddlers' activities, the test apparel obtained a higher score than existing apparel did. This indicates that the overall suitability of the newly designed apparel was improved.

Objective : The present study was carried out in order to assess the effects of Cognitive-Behavioral Group Therapy (CBGT) on victims of school violence, as assessed by the CAPS-CA. Methods : The subjects were 14 children who had experienced school violence and were subsequently diagnosed with PTSD and partial PTSD using the Clinician-Administered PTSD scale for Children and Adolescents (CAPS-CA). Seven children agreed to participate in CBGT, and they received 10 sessions of therapy. After CBGT, both the CBGT and non-CBGT groups were assessed using the CAPS-CA and School Adaptation Test. Results : The study results showed significant decreases in avoidance (p=0.010) and hyperarousal in the CBGT group (p=0.009) following the completion of CBGT. The analysis of school adaptation showed that there was a significant improvement in peer relationships after CBGT in the CBGT group (p=0.045). Conclusion : CBGT is effective in improving PTSD symptoms in children who experience school violence and subsequently suffer from PTSD.

The behavioral phenotypes of out-bred ICR mice were compared with those of in-bred C57BL/6 and BALB/c mice. In particular, this study examined the locomotor activity and two forms of hippocampus-dependent learning paradigms, passive avoidance and object recognition memory. The basal open-field activity of the ICR strain was greater than that of the C57BL/6 and BALB/c strains. In the passive avoidance task, all the mice showed a significant increase in the cross-over latency when tested 24 hours after training. The strength of memory retention in the ICR mice was relatively weak and measurable, as indicated by the shorter cross-over latency than the C57BL/6 and BALB/c mice. In the object recognition memory test, all strains had a significant preference for the novel object during testing. The index for the preference of a novel object was lower for the ICR and BALB/c mice. Nevertheless, the variance and the standard deviation in these strains were comparable. Overall, these results confirm the strain differences on locomotor activity and hippocampus-dependent learning and memory in mice.
