Modern society shares new culture derived from the fusion of various cultures unlike the past culture regulating one phenomenon of certain field as the representative icon of the era. Especially, the phenomenon of globalization acts as the catalytic agent to receive coexistence of variousness easily. Especially, in fashion industry, these flows and the view of naturalism are harmonized and new fashion trend called 'Ethnic' was embossed. As it reflects internal spirit of human being that wants to return to the memory due to expansion of material civilization, the interest in the designer pursuing it is increasing. This study tries to consider the Ethnic style displayed by Chinese American designer, Anna Sui, who pursues the eastern style with full wit and individuality. Anna Sui, who was praised by New York Times for 'the superb harmony of houte couture style and up-to-date style', created another fashion trend, romanticism in New York and she is the worldwide designer representing Ethnic. Like it, the consideration on her Ethnic style reanalyzing as eastern style provides guidance to check how designer's fashion philosophy appears in one category of America and China and new study material that enables us to understand the third world culture code as well as Anna Sui. This confirmation has the meaning as the basic material for the endless challenge to the new style that fashion will go on in the future. Anna Sui was confirmed to have been recognized as a designer who represented the ethnic collection in the United States, exerting the influence with her unique oriental background. Moreover, her design could identify the pivotal point of ethnic image by developing her unique style which is distinct from other designers in terms of silhouette, color, fabric, detail, and so on. This kind of study can provide the basic data required to understand the fashion world of designer in the future.

This study was conducted to examine the trend of national health insurance service use with relation to pregnancy, childbirth, and the puerperium among pregnant and postpartum women older than 35 over the last decade. A descriptive analysis was conducted, using the data which were drawn from the "nationwide claim database of Korean National Health Insurance Corporation(NHIC)". Data were composed of the total cases related to pregnancy, childbirth, and the puerperium (International Classification of Disease, $10^{th}$revision [ICD-10] codes O00-O99) from 2001 to 2008. During 2001-2008, the number of pregnant and postpartum women older than 35 had continuously increased and the percentage of them also had increased in both hospital and ambulatory care. There are similar trends in their total use of national health insurance service and total expenditure. According to demographic characteristics, there was the biggest increase of the percentage in residents in large cities, self-employed workers, ones in the highest income level. According to ICD-10 codes, there was the biggest increase of the percentage in O10-O16 (oedema, proteinuria and hypertensive disorders in pregnancy, childbirth and the puerperium). According to the major prevalent disease, there was the biggest increase of the percentage in O60 (preterm labor and delivery). Throughout the past decade, the necessity has been emphasized of supporting pregnant and postpartum women older than 35. But in maternal and child health care, they are in an early stage of development.

We have applied an advanced multi-aperture indexing photometry and sophisticated de-trending method to existing Taiwanese-American Occultation Survey (TAOS) data sets. TAOS, a wide-field ($3^{\circ}{\times}3^{\circ}$) and rapid photometry (5Hz) survey, is designed to detect small objects in the Kuiper Belt. Since TAOS has fast and multiple exposures per zipper mode image, point spread function (PSF) varies in a given image. Selecting appropriate aperture among various size apertures allows us to reflect these variations in each light curve. The survey data turned out to contain various trends such as telescope vibration, CCD noise, and unstable local weather. We select multiple sets of stars using a hierarchical clustering algorithm in such a way that the light curves in each cluster show strong correlations between them. We then determine a primary trend (PT) per cluster using a weighted sum of the normalized light curves, and we use the constructed PTs to remove trends in individual light curves. After removing the trend, we can get each synthetic light curve of star that has much higher signal-to-noise ratio. We compare the efficiency of the synthetic light curves with the efficiency of light curves made by previous existing photometry pipelines. Our photometric method is able to restore subtle brightness variation that tends to be missed in conventional aperture photometric methods, and can be applied to other wide-field surveys suffering from PSF variations and trends. We are developing an analysis package for the next generation TAOS survey (TAOS II) based on the current experiments.
