Objectives : In order to investigate the antidepressant effects of Forsythiae Fructus(FF), we performed the Forced Swimming Test(FST). Also the expressions of corticotropin-releasing factor (CRF), c-Fos and tyrosine hydroxylase(TH) were measured by immunohistochemical method at paraventricular nucleus(PVN), ventral tegmental area(VTA) and locus coeruleus(LC). Methods : Spraque-Dawley rats were administered FF extract(100 mg/kg, 400 mg/kg) intragastrically three times prior to the FST. Results : The duration of immobility in the FST was significantly decreased in the FF 100 mg/kg, 400 mg/kg groups(p<0.05). The expression of CRF was significantly reduced in the FF 100 mg/kg and 400 mg/kg groups(p<0.001). c-Fos expression was significantly decreased at PVN in the FF 100 mg/kg group(p=0.069). TH expression at VTA was significantly increased in the FF 100 mg/kg and 400 mg/kg groups(p<0.05). TH expression at LC was not significantly changed(p=0.346). Conclusion : According to the results, it can be suggested that Forsythiae Fructus has antidepressant effect via the decreased immobility through the reduction of CRF and c-Fos expression at PVN.

From the year 2000, an ironic phenomenon struck the Korean pop field with a number of male vocalists singing with similar voice tone colors and with almost the same vocal techniques. People called it "So-mo-ri", and this technique caught on with the public during that period of time. In the early 80s, plenty of vocalists tried to imitate Cho Yong-phil's singing method after his hit song 'Lady outside the window'. However, producing and releasing albums with the same singing method had never been done in history. In this study, I would like to analyse and conclude what the "So-mo-ri" technique was and how this technique began. I would further like to research the vocalization methods that were used.

Objectives : The purpose of this study was to determine whether the published AMI report card could reduce in-patient mortality, 7-day after discharge mortality, and length of stay (LOS). Methods : Interrupted time-series intervention analysis was used to evaluate the impact of the report card for AMI care quality in November 2005 in terms of risk-adjusted in-patient mortality, risk-adjusted 7-day after discharge mortality, and DRGs case-mix LOS using the claim data of Health Insurance Review and Assessment Service. Results : Public disclosure of AMI care quality decreased risk-adjusted in-patient mortality and DRGs case-mix LOS by 0.00050% per month and 0.042 days per month respectively, however there was no effect on risk-adjusted 7-day after discharge mortality. Patterns of effect of public disclosure on AMI outcomes were a fluctuating pattern on risk-adjusted mortalities and a pulse impact for 1 month on DRGs case-mix LOS. Conclusions : We found the public disclosure of AMI care quality had decreasing effects on risk-adjusted in-patient mortality and DRGs case-mix LOS, but the size of the effect was marginal.

We analyzed 44 and 16 types of herbal medicines for Taeumin and Taeyangin, clinically applied in Dongyisoosebowon. In order to discover the standard of herbal classification for the Sasang constitutions, four concepts of Sasang Medicine were applied. These included 'Sadangron (theory of four groups)', 'Seungganggaehap (ascending-descending and gathering-dispersing)', 'Pyorihanyoul (exterior-interior and hot-cold)',and 'Hyungchiaekmi (fragrance, smell, bodily fluid and taste)'. According to these analyzing methods of herbal properties, we have reached the following conclusions: Herbal medicines for 'Taeumin' are characterized by opening energetics that reinforce dispersing Qi. The 'Exterior cold disease' is treated with herbs that ventilate the lungs and disperse dampness in three ways: by moistening the lungs, by releasing exterior, and by resolving dampness. The 'Interior heat disease' is treated with herbs that clear the liver and disperse heat in two ways. One by clearing liver heat through dispersing damp-heat of the small intestine and the other by opening orifices. Herbal medicines for Taeyangin are characterized by those that gather energy inward. They include herbs that treat beriberi, dystrophy of the extremities and vomiting, as well as, fish, shellfish, fruits and vegetable.

Objectives : Increasing evidence has linked chronic inflammation to a number of neurodegenerative disorders including Alzheimer's disease(AD), Parkinson's disease(PD) and Huntington's disease(HD) in the inflammatory process. Uncontrolled activation of microglia may directly toxic to neurons by releasing various substances such as inflammatory cytokines ($TNF-{\alpha}$, $IL-1{\beta}$ and IL-6), NO, PEG2 and superoxide. In this study, the immunomodulatory effects of the herbal extract Panax notoginseng on cultured BV2 microglial cells and primary microglia were investigated to address potential therapeutic or toxic effects. Notoginseng radix extracts extracted from the root of the plant using Methanol. Methods : Cells were stimulated with LPS and treated with notoginseng at different concentrations. Results : Notoginseng significantly decreased LPS-induced production of $TNF-{\alpha}$ and IL-6 by the cultured microglial cells in a dose-dependent manner. The activation of iNOS mRNA and secretion of nitric oxide(NO) in microglial cells were inhibited in microglial cells in a dose-dependent manner by notoginseng. Conclusion : These results indicate that notoginseng inhibits LPS-induced activation of microglial cells and demonstrates notoginseng possess anti-inflammatory and immunosuppressive properties in vitro.

Objectives The purpose of this study is to emphasize the importance of preventing precocious puberty. This study assessed current number of the patients with early puberty and their medical expenses from 2010 to 2015. Methods Using the data from Korean Statistical Information Service and Heathcare Bigdata Hub, number of patients diagnosed with precocious puberty by gender, age, and year from 2010 to 2015 were reviewed. Also, annual medical insurance expenses and the incidence of leuprorelin use were reviewed. Results Number of the patients with precocious puberty has increased from 29,251 in 2010 to 75,945 in 2015. Total medical insurance expenses have increased from 25,716,431 won in 2010 to 56,367,981 won in 2015. The use of lueprorelin also has increased annually from 11,097,590,000 won in 2010 to 21,617,585,000 won in 2015. Conclusions As a result, the patients diagnosed with precocious puberty are increasing in number, and their medical costs have been rising as well. It may be necessary to control the environmental causes of precocious puberty to reduce not only the physical and psychosocial health problems, but also the social costs.

Super-distribution is essential for revitalization of digital contents industry in DRM system. Since existing DRM systems emphasize on security for intellectual property rights, it became restrictions to content distribution and the consumer rights. This paper suggests license management mechanism which strengthen super-distribution between consumers. It is to manage distribution history for each content by inserting consumer's identification information in content head. Client can verify security by comparing header and license after issuing license. It classifies the type of distribution and license, and then applies adaptive distribution methods. It can revitalize contents distribution by releasing proper license for super-distribution.

Protection against disclosure of survey respondents' identifiable and/or sensitive information is a prerequisite for statistical agencies that release microdata files from their sample surveys. Coarsening is one of popular methods for protecting the confidentiality of the data. Grouped data can be released in the form of microdata or tabular data. Instead of releasing the data in a tabular form only, having microdata available to the public with interval codes with their representative values greatly enhances the utility of the data. It allows the researchers to compute covariance between the variables and build statistical models or to run a variety of statistical tests on the data. It may be conjectured that the variance of the interval data is lower that of the ungrouped data in the sense that the coarsened data do not have the within interval variance. This conjecture will be investigated using the uniform and triangular distributions. Traditionally, midpoint is used to represent all the values in an interval. This approach implicitly assumes that the data is uniformly distributed within each interval. However, this assumption may not hold, especially in the last interval of the economic data. In this paper, we will use three distributional assumptions - uniform, Pareto and lognormal distribution - in the last interval and use either midpoint or median for other intervals for wage and food costs of the Statistics Korea's 2006 Household Income and Expenditure Survey(HIES) data and compare these approaches in terms of the first two moments.
