Objective : This study was designed to assess the protective effects of Chengwhabosimtang on the animal model of depression, chronic mild stress(CMS). Method : Male Sprague-Dawley rats were used for this experiment. The subjects were divided into 3 groups ( 1. CMS-drug: Chengwhabosimtang administered during CMS treatment, 2. CMS-vehicle: water administered, 3. normal ). After 4 weeks of CMS treatment, they were executed Forced swimming test(FST) and Elevated plus maze. Tyrosine hydroxylase(TH) in ventral tegmental area(VTA) and c-Fos in paraventricular nucleus(PVN) were measured. Result : 1. In FST, CMS-drug group showed significantly decreased immobility behavior. 2. CMS-drug group showed no significantly lower TH level in VTA than CMS-vehicle group. 3. CMS-drug group showed significantly less c-Fos expressed cell bodies in PVN than CMS-vehicle group. 4. In Elevated plus maze, CMS-drug group showed no significantly anxiety. Conclusion : These results suggest that Chengwhabosimtang may have protective antidepressant effects in CMS model rats. And these effects could be explained by the elevated stress-copying behaviors which are related with PVN of hypothalamus and dopaminergic neurons in VTA.

A lot of designers are adopting a mixed imitation as techniques of cretion because cultural boundary and structure of meaning in the era of post-modernism are collapsed and dissolved. I raise up a question mark to how can genuine and creative designers can be identified at this epoch when we are today familiar with the trend of informationalization, opening and globalization. Characterisitics of multi-culturalism and compromising blending are meshed with appearance of a theory of disorganization and consumer-driven economic activity of multi-national enterprises in the age of post capitalism. Accordingly it can be said that designers are leaning upon public and consumeroriented pattern rather than pursuing a creative cultural production. With mass media in rapid advancement and public culture in father dissemination, mass production and mass re-production became a natural cultural phenomenon strengthen ing its root. Creative designers somewhat slow and limitative in pace of adaption to rapid changing society amid such social backgrounds and flooded information are coming to dead-end of wall. A mixed imitation as techniques of creation is a result of borrowing, duplicating or re-combining of existing things because the mixed imitation is equivalent to borrowing, copying, compilation and recombination of well-known artworks, motive, diverse people's cultural features, image, techniques and the likes. It is too delicate thing for one to definitely distinguish such cultural phenomenon from either one as creative work or a plagiarized work. Looking into the facts as they are, we should recognize the designers limitation in their creative works by means of the mixed imitation. thus we can have a view upon them from a criticizing standpoint against the designers creation and imitation. On the other hand, when we look at things how the mixed imitation appears in the fashion as a piece of culture, we can understand something of the contemporary designers. I try to find a significance in seeking out a method of approaching to creative fashion designers direction in future times.

The purpose of this study is to investigate Modernism of Gabrielle Chanel in respect to her fashion business. Chanel always considered the work of a fashion designer 'a technique, a craft, a trade' and chastised couturiers who looked upon themselves as artists. She was the first to cater to the public in its broader sense and to produce standard which appealed to every taste, the first to democratize the art of dressmaking for purely economic reasons. The results were as follows; 1. Chanel personified ~his new spirit of independence and evolved a style of dress for the modern, liberated woman. 2. Chanel excelled at fabrics, their interpretation, and an ability to use them. She had taken a humble material, one that was used by men and that they had shunned, and turned it into a fashionable fabric. In the process she also accelerated the growth of the ready-to-wear industry for it was a fabric within the financial reach of the majority of woman who wanted to dress fashionably but were not well off. 3. Chanel thought black chic and would never go out of fashion. As American Vogue for 1 October 1926 prognosticated, her little black dress became a kind of uniform. 4. Chanel represented an exception among couturiers because she was flattered that her styles were so popular and widely copied. She believed that her style would be affirmed by high-street copies-after all, copying is the sincerest form of flattery. 5. Chanel changed the concept of costume jewellery. It was not an original idea of Chanel's. Whereas Poiret had pioneered the original idea of costume jewellery, it was Chanel's avant-garde way with it not to mention her usual deceptive simplicity and supreme artistry that made costume jewellery evolve a successful and lucrative part of the fashion industry.

The Purpose of this study is to explore he mathematical discovery and justification of six 10th grade students through mathematical modeling activities in spreadsheet environments. The students investigated problem situations with a spreadsheet, which seem to be difficult to solve in paper and pencil environment. In spreadsheet environments, it is easy for students to form a data table and graph by inputting and copying spreadsheet formulas, and to make change specific variable by making a scroll bar. In this study those functions of spreadsheet play an important role in discovery and justification of mathematical rules which underlie in the problem situations. In modeling activities, the students could solve the problem situations and find the mathematical rules by using those functions of spreadsheets. They used two types of trial and error strategies to find the rules. The first type was to insert rows between two adjacent rows and the second was to make scroll bars connecting specific variable and change the variable by moving he scroll bars. The spreadsheet environments also help students to justify their findings deductively and convince them that their findings are true by checking various cases of the Problem situations.

Man pursues health as his basic right. Therefore, the government should try to preserve the right of the people's health and carry out the policy of medical treatment for that. But the system of our medical care is advantageous to the medical institutions, which produce medical goods each people buys and sells freely, more than to the maintenance and improvement of their health. That is to say, the first aim of the institution is not the healthy preservation of the people but their accumulation of riches. The medical conflicts are the social situation which is happening between those who produce medical treatment and the patients who consume it. Its behinning comes from the lack of belief by the inhuman relationship between patients and doctors. According to thelatest investigation, the patients of oriental clinics look more content than those who go to common hospitals. The reasons are as follows; fitness to one's physical constitution, the kind altitude of doctors and the view of oriental medicine toward human body. Though the content degreee is higher than western medicine, such conclusions result from the present condition the number of the patients is less. In short, the first, since the right of patients is higher and the fields make more variors and popular, the conflicts and mistakes go on increasing. The second, in their activity of treatment, the legal importance of atlention and explanatory obligation should be considered seriously so as not to break out medical mistakes. The third, in the center of technical books which are accepted by the academic world, the clinical exertion doing treatment is needful. The fourth, as the direct order of medical justification the self-determination of patients should be respected. The fifth, because the process and record of treatment become important in the time of emergency legally, the conversations and movements as well as the details of treatment must be recorded. The sixth, the academic effort about the settlement institution or the legal system is necessary.

The wide spread of genuine and fake information on internet has lead to various studies on text analysis. Copying and pasting others' work without acknowledgement, research results manipulation without proof has been trending for a while in the era of data science. Various tools have been developed to reduce, combat and possibly eradicate plagiarism in various research fields. Text similarity measurements can be manually done by using both parametric and non parametric methods of which this study implements cosine similarity and Pearson correlation as parametric while Spearman correlation as non parametric. Cosine similarity and Pearson correlation metrics have achieved highest coefficients of similarity while Spearman shown low similarity coefficients. We recommend the use of non parametric methods in measuring text similarity due to their non normality assumption as opposed to the parametric methods which relies on normality assumptions and biasness.

Digital watermarking has drawn extensive attention for protecting digital contents from unauthorized copying. This paper proposes a new watermarking scheme in frequency domain for copyright protection of digital audio. In our proposed watermarking system, the original audio is segmented into non-overlapping frames. Watermarks are then embedded into the selected prominent peaks in the magnitude spectrum of each frame. Watermarks are extracted by performing the inverse operation of watermark embedding process. Simulation results indicate that the proposed scheme is robust against various kinds of attacks such as noise addition, cropping, resampling, re-quantization, MP3 compression, and low pass filtering. Our proposed watermarking system outperforms Cox's method in terms of imperceptibility, while keeping comparable robustness with the Cox's method. Our proposed system achieves SNR (signal-to-noise ratio) values ranging from 20 dB to 28 dB. This is in contrast to Cox's method which achieves SNR values ranging from only 14 dB to 23 dB.

Panax ginseng has often been suggested as a geriatric restorative. This study is a double blind crossover trial to test whether ginseng can improve function in subjects with the depression and reduced abilities associated with senescence. 49 screened subjects were given 1500 mg Korean Red ginseng and identical placebo each for ten days, with a washout period in between the dosages. Standard tests of mental function, neuromuscular reflexes, responsiveness, mood and well being were used. The subjects were somewhat better at the co-ordination and speed test ('number copying') but tests of concentration and memory ('Concentration', 'Paired Association', 'Digit Span' and 'Object Learning') gave equivocal results. There were small improvements in mood and well being ('Life Satisfaction' and 'General Health Questionnaire') while the subjects indicated increased energy, alertness and less sleep, but also less happiness on the daily analogue scales. The major result was a highly significant improvement in reactivity, speed and co-oridnation at the tapping test, and the visual, auditory and disjunctive reaction timer. These are the most objective and accurate tests used in this trial. It is therefore concluded that ginseng can increase function in senile individuals. This effect is most easily visualisable in objective psychophysical tests, rather than the more subjective memory and concentration tests.

The application of computer graphics, which is characterized by reality, has even reinforced reality of image and motion expression in digital animation. But reality of digital animation succeeds to traditional aesthetic characteristics of animation for overcoming physical limitations of the real world and realizing imagination through transformation, rather than copying actuality as it is. But it does not succeed to drawing animation wholly. Digital animation adds cartoonish transformation, based on three-dimensional realistic expression and those animation situations look as if they get over realistic restrictions, while drawing animation constantly reminds of mediality in drawing motion, based on two-dimensional plane and handwork. n other words, cartoonish exaggeration that is intermittently inserted between these reinforced realities, expresses digital animation's own aesthetic characteristics as a dialectical sum by crashing into contrast coming from a cross between reality and imagination.

Objectives： The rate of adolescent smoking is important because lead to adult smoking. And early onset of smoking is associated with chronic disease in adult life. The purpose of this study is to describe the smoking status of adolescents and identify the risk factors for smoking in each school. Methods： We selected the participant schools that are located in Yang-cheon Gu, Seoul, Korea, considering the social economic status. The subjects were included 719elementary school students,1,251 middle school students and 1,513 high school students. Self-reported questionnaires were administrated between December 16 and December 24 , 2002. Students were informed in writing that the survey was voluntary. The response rate was 98.7, 81.1 and 95.4 in elementary, middle, and high school, respectively. Results： The results of this study were as follows： 1) Students who have attempted to smoke were 8.8% in elementary school, 29.3% in middle school and 35.0% in high school. 2) The current smokers were 2.0%, 7.9% and 11.5% in elementary, middle and high school, respectively. 3) In elementary school, smoking of mends and physical health were significantly predicted the attempt to smoke. Stress, smoking of mends, alcohol, and binge drinking were associated with the attempt to smoke of middle school students. In high school, the attempt to smoke was related to gender, maternal education, depression, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking. 4) Current smoking was associated with smoking of mends and binge drinking in middle school and gender, school performance, smoking of brothers, smoking of mends, alcohol, and binge drinking in high school in multiple logistic regression. Conclusion： There is a need for health education and specific strategies to help adolescents prevent from smoking. Smoking prevention programs which include risk-taking behavior such as alcohol, method of copying with stress, and supporting environment were required.
