The present study attempted to analyze the behavioral patterns and attitudes of high school girls toward apparel ads in magazines in relation to their physical self-concept. The study used a self-administered questionnaire. The sample consisted of 419 students at 3 girl's high schools located in Seoul. Likert scales were used for most measures with 1=never or very unimportant and 5=always or very important. Physical self-concept was measured on the basis of W S. Jung's Standardized Self-concept Test and Tennessee Self-concept Scale. Percentage, t-test, and Chi-square were used for the analysis of the data. Results are as follows: (1) Those with a high sense of physical self-concept read more magazines. (2) Those with higher sense of physical self-concept showed greater interest in magazine ads, consulted magazines for fashion trends, found ads more useful, and more often expressed satisfaction with the ads, than the lower self-concept group. (3) Advertisers should attempt to gain a deeper understanding of the socio-psychological characteristics of their readership as self-concept appeared to be related to several magazine readership attitudes and behaviors. Apparel ads targeting high school girls should consider the importance of company ads.

We tested whether ginsenosides $Rg_3$-standardized ginseng extract (RGE) has anti-stress effects in restraint-stressed animals. RGE increased time spent in the open arms and open arm entries in the elevated plus-maze test. In addition, RGE blocked the reduction of center zone distance and stereotypes behaviors in the open-field test. RGE also increased head dips in stressed mice, indicating anxiolytic-like effects. Stress decreased movement distance and duration, burrowing, and rearing frequency but increased face washing and grooming. RGE significantly reversed burrowing and rearing activity in stressed mice. In addition, we measured sleep architecture in restraint stressed rats using EEG recorder. Stress increased rapid eye movement (REM) sleep, but total sleep and non-rapid eye movement (NREM) sleep were not changed. RGE did not affect sleep architecture in stressed rats. These behavioral experiments suggest that RGE has anti-stress effects in restraint-stressed animal models.

The purpose of this study was to investigate the relationship of toddlers' vocabulary ability with reading activities and teachers' verbal and nonverbal behaviors during book reading. The subjects were 52 teachers and 104 toddlers at age 2. Lee and Kim (2004)'s categories of the Teachers' Verbal Behaviors, the categories of the Nonverbal Behavioral Analysis(Kim. 2005), and the Peabody Picture Vocabulary Test-Revised (Kim, et al.1995) were used. The data was analyzed by t-test, ANOVA, and Correlations. The results indicated that there were significant correlations in the subcategories of reading activities in classrooms, teachers' picture book reading behaviors, and toddler's vocabulary ability. The toddler's vocabulary ability increased as the 'interacting time both before and after book reading' became longer. The toddler's vocabulary ability increased as 'connecting with previous experience', 'asking questions for confirmation', 'acknowledging,' and 'expanding' of verbal behavior, as well as the nonverbal behavior, such as 'requesting behavior', 'emotional contact,' and 'empathetic behavior.' In conclusion, teachers' reading behaviors and activities were related to toddlers' vocabulary ability.

This study was performed to investigate the anti-depression effect of Guibiondamtang in rat model of depression. The rats in the experiment were stratified into 3 groups, ie, Guibiondamtang, saline, normal (non-stressed) groups. Chronic exposure to mild unpredictable stress such as white noise, flashing lights and restriction of food and water, causes the behavioral symptoms correspondent to depression. Consumption of 1% sucrose solution fell in rats exposed to CMS for 4 weeks. In the open field test , the exploratory activity ie. locomotion and centering decreased after CMS. We then evaluated the sucrose consumption and activity during 4 weeks of treatment with experimental drugs. The results were as follows: 1) There was no relation between sucrose intake and weight. 2) The Guibiondamtang(歸脾溫膽湯) group reinstated sucrose consumption within 5-6 weeks while having no influence on sucrose intake in normal group. 3) The Guibiondamtang(歸脾溫膽湯) group restored some exploratory activity in the open field test. 4) The Guibiondamtang-group had a-reduced potentiated startle response.

We examined whether wogonin (WO) improved hippocampal neuronal activity, behavioral alterations and cognitive impairment, in rats induced by administration of trimethyltin (TMT), an organotin compound that is neurotoxic to these animals. The ability of WO to improve cognitive efficacy in the TMT-induced neurodegenerative rats was investigated using a passive avoidance test, and the Morris water maze test, and using immunohistochemistry to detect components of the acetylcholinergic system, brain-derived neurotrophic factor (BDNF), and cAMP-response element-binding protein (CREB) expression. Rats injected with TMT showed impairments in learning and memory and daily administration of WO improved memory function, and reduced aggressive behavior. Administration of WO significantly alleviated the TMT-induced loss of cholinergic immunoreactivity and restored the hippocampal expression levels of BDNF and CREB proteins and their encoding mRNAs to normal levels. These findings suggest that WO might be useful as a new therapy for treatment of various neurodegenerative diseases.

This study was performed to investigate the influence of the amino acid composition of diet and environment on RNA, protein content in brain and learning ability in rats. Forty-two Sprague-Dawley male rats were divided into six groups according to type of diet, casein, soybean meal, or corn gluten and rearing condition, isolated or enriched. They were fed foods ad libitum for 6 weeks. A water maze was used to test behavioral performance for 3 weeks from 4th week. The rats were sacrificed at 6th week and their whole brains were taken and frozen for assay of RNA and protein. The results were summarized as follows : 1) The body weight gain for the experimental periods of corn gluten group was significantly lower than the casein and the soybean meal group. 2) The brain weight of the corn gluten group was significantly lower than the casein and the soybean meal group and the environmental enrichment slightly increased it among rats fed the corn gluten diet. 3) The total RNA contents were the greatest in the environmentally enriched casein group. The brain protein contents of the isolated corngluten group was the smallest. However, the contents of the enriched corn gluten group were similar to those of the others. 4) In the water maze test, the isolated corngluten group spent significantly more time than the others. Environmental enrichment could decrease time to perform the task of the maze.

Background : Acupuncture has been used as a clinical treatment in Oriental medicine for various diseases including pain relief. The descending pain control system of periaqueductal gray (PAG) is a powerful pain control system in mammalians. Expression of c-Fos is used as a marker for stimuli-induced metabolic changes of neurons. Objective : In the present study, the effects of acupuncture on analgesic effect in visceral pain were investigated through the writhing reflex and c-Fos expression in ventrolateral PAG (vlPAG) area using immunohistochemistry in mice. Method : For the writhing test, mice were divided into five groups. Immediately after finishing the behavioral test, the animals were weighed and overdosed with Zoletil. After a complete lack of response was observed, the brains of the mice were dissected into serial coronal sections, and c-Fos immunohistochemistry was performed. Statistical analysis of all data was performed using one-way ANOVA. Result : The present results showed that acupuncture affected the writhing reflex and that Choksamni (zusnali) acupoint and aspirin significantlysuppressed acetic acid treatment-induced increased writhing reflex, and the expression of c-Fos in vlPAG was significantly increased in the acupunctured group. Conclusion : The present study suggests that acupuncture has an antinociceptive effect on acetic acid-induced visceral pain by increase of c-Fos expression in mice. Aspirin also showed analgesic effect, however the mechanism is different from the acupuncture.

Audiometric calibration is a prerequisite for securing the reliability of audiometric test results by checking the internal consistency of the relevant instrument. The purpose of this review is to help instrument operators understand the calibration procedure of aural acoustic immittance instrument which is frequently used for objective assessment. By referring to the latest international standards and the national standards relevant to the aural acoustic immittance instrument, the following parameters will be reviewed: 1) introduction of performance characteristics, 2) detailed procedure of the calibration method. According to the newest international and national standards [IEC 60645-5 (2004), ANSI S3.39-1987 (R2012)], the aural acoustic immittance instrument basically includes six components: 1) calibration cavity, 2) acoustic immittance analysis system, 3) probe assembly/unit and signal, 4) pneumatic air-pressure pump system, 5) acoustic reflex activator system and 6) tympanogram and acoustic reflex plotting system, each of these components should meet set standards. The result of behavioral hearing tests is influenced by various complex factors including the examinee's cooperation, background noise of the examination room, measurement method, skill level of the audiologist and calibration status, but the objective hearing tests is more influenced by the calibration status of the instrument than any other factors. The audiologist should take full responsibility for the reliability of the hearing test result, so he/she should carry out the calibration check and adjustments of aural acoustic immittance instrument periodically and maintain the instrument continuously by referring to the newest standards and the manufacturer's instruction manual.
