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.

2000년대 들어서 가요계는 이전에는 볼 수 없었던 특이한 현상이 발생하였다. 많은 남자 가수들이 똑같은 목소리, 똑같은 창법으로 노래를 부르는 현상이 그것이다. 혹자들은 그것을 "소몰이 창법"이라 이름 붙였는데 당시에는 특이한 목소리로 인해 대중들에게 상당한 인기를 끌었다. 80년도 초 조용필의 "창밖의 여자"가 히트를 하면서 많은 가수들이 조용필의 창법을 익히고자 했던 적은 있었지만 많은 남자 가수들이 똑같은 목소리와 창법으로 앨범까지 발표한 적은 유래가 없었다. 본 연구에서는 "소몰이 창법"이 무엇인지 어떻게 시작 되었는지 또한 발성의 특징은 무엇인지 등에 관한 연구 논문이다.

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.

DRM 시스템의 재배포 기능은 디지털 콘텐츠 산업 활성화에 필수적이다. 기존의 DRM은 지적재산권의 안전에 치중하였기 때문에 배포에 대한 제약과 소비자 권리를 억제하는 요소가 된다. 본 연구는 사용자간 재배포를 강화할 수 있는 라이센스관리 모델을 제시한다. 배포 시에 콘텐츠 헤더에 사용자의 식별정보를 넣어서 배포함으로써 배포 이력을 관리한다. 라이센스 발급 후에는 클라이언트가 헤더와 라이센스의 식별정보를 비교하여 안전을 확인한다. 배포 형식과 라이센스를 유형별로 분류하여 적합한 배포 방식을 적용하고 적합한 라이센스를 발급함으로써 배포를 활성화할 수 있다.

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.
