While the women of the Korea Dynasty wore hat(笠子) and Mongsu(蒙首) on top of it when going out, the Yi Dynasty, due to more strict Contucian ethics and isolated way of life, had seen the development of the covering clothes, rather veil, for avoiding the opposite sex with diversity and both men and women began wearing PHO(coat), a Korean topcoat over the head and thurs called Changots, but originally PHO for men was named Changyi a men's outer coat. Neuwul(羅兀), like Mongsu(蒙首) of Korea Dynasty was a thin black hood worn on top of the Wowllip or a kind of skirt draped over the head and the latter was called Changots, very similar to Sgaechima, a kind of long hood formally worn by women. Meanwhile, local women wore a long veil with no arm sleeves dubbed Cheunyi(薦衣) But since western civilization and culture landed on Korea around the end of the 19th century, the women's social status has been raised to almost the same level with men and the way of life has changed towards openness, in which men and women have almost daily contact with one another, so these days we can hardly find such veil style covering clothes around us.

Due to recent changes in increased life expectancy, economic power and social development, the new senior generation (focusing on people in their fifties) represents a new market power with strong competitiveness. The new senior generation is the generation after the baby boomers, with characteristics that include a high-level of education, increased income, a high-level of consumption, increased assets, self-fulfillment desires and individuality. Demands in the senior fashion industry are expected to gradually increase and the underwear industry that targets the new senior generation is expected to grow rapidly. These demands will require product development for the new senior generation based on emotional and socio-cultural characteristics. The current new senior underwear market is under the process of R&D with a focus on body shape changes; however, there are limited studies on emotional and socio-cultural approaches. This study formulates a basic design plan for different age groups based on an analysis of the situation of bra wear (current inconveniences, demand and needs) by women in their fifties and over. Subsequently, a functional active bra top that considers activity and comfort was proposed for women in their fifties, an all-in-one foundation bra top that shapes the body was proposed for women in their sixties, and comfort bra tops that are comfortable and easy to put on and take off were proposed for women in their seventies and over.

In case of preparation of ITO thin film for using top electrode of Top-emitting Organic Light Emitting Diodes(TOLEDs), the ITO thin film should be prepared at room temperature and low oxygen gas flow condition in order to reduced the damage of organic layer due to the bombardment of highly energetic particles such as negative oxygen ions which accrued from the plasma. In this study, the ITO thin film with high optical transmittance and low resistivity prepared as a function of oxygen gas (0 ${\~}$ 0.8 sccm) and Ar gas was fixed at 20 sccm by the Facing Targets Sputtering (FTS) method. The electrical and optical properties of ITO thin films were measured by Hall effect measurement, UV/VIS spectrometer, respectively In the results, we obtained the ITO thin film with lowest resistivity($3{\times}10^{-4} {\Omega}{\cdot} cm$) at oxygen gas flow 0.2 sccm and optical transmittance over $80\%$ at oxygen gas flow over 0.2 sccm.

RWR (Random Walk with Restart) is frequently used by many graph-based ranking algorithms, but it does not consider a signed graph where edges may have negative weight values. In this paper, we apply the Balance Theory by F. Heider to RWR over a signed graph and propose a novel RWR, Balanced Random Walk (BRW). We apply the proposed technique into the domain of recommendation system, and show by experiments its effectiveness to filter out the items that users may dislike. In order to provide the reasonable performance of BRW in the domain, we modify the existing Top-k algorithm, BCA, and propose a new algorithm, Bicolor-BCA. The proposed algorithm yet requires employing a threshold. In the experiment, we show how threshold values affect both precision and performance of the algorithm.

This study investigates how consumers perceive the collection of behavioral information through 'cookies' on OTT platforms and the impact it has on personalized services. Through SPSS analysis on 120 consumers, which was conducted to examine four hypotheses, correlations were found between awareness of OTT companies' behavioral information collection and online tracking recognition, awareness and willingness to provide cookies, and the extent of confirming behavioral information collection terms during registration and online tracking recognition. The study concludes that consumer knowledge about behavioral information significantly influences the importance and intention to use personalized services, highlighting the need for regulatory measures by both companies and government entities.

Background: Cancer is currently one of the main public health problems all over the world and its economic burden is substantial both for health systems and for society as a whole. To inform priorities for cancer control, we here estimated years of potential life lost (YPLL) and productivity losses due to cancer-related premature mortality in Iran from 2006 to 2010. Materials and Methods: The number of cancer deaths by sex and age groups for top ten leading cancers in Iran were obtained from the Ministry of Health and Medical Education. To estimate the YPLL and the cost of productivity loss due to cancer-related premature mortality, the life expectancy method and the human capital approach were used, respectively. Results: There were 138,228 cancer-related deaths in Iran (without Tehran province) of which 76 % (106,954) were attributable to the top 10 ranked cancers. Some 63 % of total cancer-related deaths were of males. The top 10 ranked cancers resulted in 106,766,942 YPLL in total, 64,171,529 (60 %) in males and 42,595,412 (40%) in females. The estimated YPPLL due to top 10 ranked cancers was 58,581,737 during the period studied of which 32,214,524 (54%) was accounted for in males. The total cost of lost productivity caused by premature deaths because of top 10 cancers was 1.68 billion dollars (US$) from 2006 to 2010, ranging from 251 million dollars in 2006 to 283 million dollars in 2010. Conclusions: This study showed that the economic burden of premature mortality attributable to cancer is significant for Iranian society. The findings provide useful information about the economic impact of cancer for health system policy/decision makers and should facilitate planning of preventive intervention and effective resource allocation.

Recently, Silicon On Insulator (SOI) devices emerged to achieve better device characteristics such as higher operation speed, lower power consumption and latch-up immunity. Nevertheless, there are many detrimental defects in SOI wafers such as hydrofluoric-acid (HF)-defects, pinhole, islands, threading dislocations (TD), pyramid stacking faults (PSF), and surface roughness originating from quality of buried oxide film layer. Although the number of defects in SOI wafers has been greatly reduced over the past decade, the turn over of high-speed microprocessors using SOI wafers has been delayed because of unknown defects in SOI wafers. A new characterization method is proposed to investigate the crystalline quality, the buried oxide integrity and some electrical parameters of bonded SOI wafers. In this study, major surface defects in bonded SOI are reviewed using HF dipping, Secco etching, Cu-decoration followed by focused ion beam (FIB) and transmission electron microscope (TEM).
