Online streaming wars are intensifying. Netflix is known as the market leader in the streaming business. However, since 2019, Netflix has been losing subscribers in the United States and is at a turning point where it needs to reassess its current position in the market. While Netflix is losing dominance, rivals Amazon Prime and Hulu continue to gain market shares. Studies from Deloitte and PricewaterhouseCoopers indicated a new shift in the streaming landscape caused by the abundance of streaming options and rising subscription costs. Recent surveys showed that consumers are excited about new streaming services, such as Disney +. Nearly two-thirds of consumers intend to terminate or downgrade one or more of their current subscriptions to make room for a new service. Moreover, it seems that consumers want ad-supported options. In Deloitte's latest Digital Media Trends survey, 65% responded that they would watch ads to eliminate or reduce subscription costs. Seventy percent of Hulu's subscribers choose its lower-priced ad-supported plan. NBC recently launched its own streaming service, Peacock, with a free ad-supported option. This opposes Netflix's brand identity of "no ads" and premium differentiation. With increasing pressure from competition and the growing risk of subscriber loss, Netflix needs to diversify its price plans. The company could try implementing the lower-priced mobile-only plan they are currently testing or plan to test in other regions. Netflix should also consider features or benefits for loyal subscribers to maintain a stronger consumer base.

The (Korean) Medical Services Act revised in 2009 introduces the accreditation of specialty hospital. When a hospital meets prescribed standards, passes a board review, and is accredited as a specialty hospital by the Minister of Health and Welfare, then it may use 'specialty hospital' in its name and certification mark of specialty hospital. The problem is that the (Korean) Fair Trade Commission and the (Korean) Ministry of Health and Welfare, both of which have authorities to regulate advertising in general and in health care service in turn, announced the guidelines to prohibit internet (portal) service providers to provide keyword search ads service using key-words such as 'specialty' or 'specialized in' for those who are not accredited by the Minister of Health and Welfare. In this article, whether these guidelines can be justified by the current regime and whether the current specialty hospital policy is agreeable would be examined. To do this, the legal nature of accreditation of specialty hospital, the limit of advertisement regulation, the law of keyword search ads, and the liability of internet service providers also would be analyzed.

This study aims to analyze the characteristics of transnational cigarette companies' strategies to expand the female market in Korea after the market opening of 1988. Focusing on 'Virginia Slims' and 'Finesse', which are the PM and BAT's representative female brands, this study explores whether their typical advertising strategies were transformed in Korean market. After 3years from the market opening, 'Virginia Slims' gave up its brand identity and the strategy was so successful that 'Virginia Slims' continued to be 2nd best-selling brand in the imported cigarette market in Korea. In contrast, 'Finesse' maintained a typical women's cigarette image during the 1990s and consequently occupied the highest brand awareness as a female cigarette but lower market share than Virginia Slims. TTCs adapted to a doubly obstructed Korea market with its strong taboo against female smoking and a comparatively stronger legal ban on all cigarette ads targeting women. However, diverse indirect cigarette ads and promotions, which circumvented regulations, suggest that ads transforming was not to give up Korean female customers. Furthermore, the cigarette ads that the soft and mild taste of female brands are associated with healthy image rather than gendered image may appeal to Korean women without touching their emotions and desires.

This paper presents a design of low power CMOS LNA(Low Noise Amplifier) for 2.4 GHz ZigBee applications that is a promising international standard for short area wireless communications. The proposed circuit has been designed using TSMC $0.18{\mu}m$ CMOS process technology and two stage cascade topology by current reuse technique. Two stage cascade amplifiers use the same bias current in the current reused stage which leads to the reduction of the power dissipation. LNA design procedures and the simulation results using ADS(Advanced Design System) are presented in this paper. Simulation results show that the LNA has a extremely low power dissipation of 1.38mW with a supply voltage of 1.0V. This is the lowest value among LNAs ever reported. The LNA also has a maximum gain of 13.38dB, input return loss of -20.37dB, output return loss of -22.48dB and minimum noise figure of 1.13dB.

Acidic air pollutants were collected to characterize indoor air quality in a residential area in the summer. All indoor and outdoor samples were measured simultaneously using an annular denuder system(ADS) in Seoul. The data set was collected from July 26 to September 11, 1997. The mean indoor/outdoor ratios measured from this study were : 0.34 for $HNO_3$; 0.91 for $HNO_2$; 0.22 for $SO_2$; 1.34 for $NH_3$; 0.78 for $PM_{2.5}(d_p$ <2.5 $mutextrm{m}$); 0.90 for $SO_{4}^{2-}$; 0.68 for $NO_{3}^{-}$ and 0.79 for $NH_{4}^{+}$. Indoor concentrations of $HNO_3$, $SO_2$ and $PM_{2.5}$ were highly correlated with the outdoor concentrations. The relationship between indoor and outdoor air is dependent, to a large extent, on the rate of air exchange between these two environments. A tracer-gas decay technique with sulfur hexafluoride ($SF_{6}$) as a tracer gas was used to estimate the air exchange of a private home in the summer. The average air exchange rate was estimated to be 23.7 hr(sup)-1. The deposition velocities for $SO_{4}^{2-}$, $NO_{3}^{-}$ and $NH_{4}^{+}$ calculated were 0.17, 0.69 abd 0.39 cm/sec, respectively.

The discharge characteristics of 3 electrcdes AC surface discharge plasma display were analyzed. For an unstable state of the discharge which appeared at the maximum discharge voltage, it is found that a parbal erase of the wall charge by the second discharge is a cause. Based on the second discharge, new operation margin considering the interrelation between the address discharge and the display discharge was defined and the validity of it was verified by the experiments. It is necessary to decrease the acklress pulse width for high-speed addressing. However, the operation margin of the ackIress pulse decreases as the pulse width of it becomes narrower. If the address pulse width is wider than l[ps], the operation margin of the display discharge is not related to the address pulse width. From the experimental result, image or 8bit 253 gray level was displayed on PDP with the cell structure of the HDTV class by using the high-speed address ADS drive methcd with pulse width of $1[{\mu}s]$ and the brightness of $560[cd/m^2]$ was obtained. ained.

This study focuses how storytelling in advertising has introduced and determinated mobile telecommunication technology as a digital technology in the process of its rapid acceptance into our society. The objective of the study is to confirm the role of advertising in introducing technology into a society and the relation between advertising and technology by chasing the digital discourse produced by advertising while digital technology permeates through our society. This study uses content analysis for basic research and discourse analysis for exploring the change of digital discourse in the corporate ads of mobile telecommunication companies since 15 years. As a result, 1) 'digital' and 'analogue' discourses were found to be competing and contesting with each other across the years. Digital discourse mainly connected to a new mode of thinking and lifestyle appeared predominant in the early period, but eventually gave way to its alternative, analogue dialogue. The analogue discourse was brought with such values as humanity, slowness and happiness, which has been by and large undermined by the new, fancy digital technologies and their world, 2) whereas some mixed forms of these two discourses were also found. 3) In the meantime, digital-based mobile communication technologies were identified with people who think outside of box and have an innovative attitude toward their life in the ads. Through this signification process, the ads contribute to permeation of mobile communication technology into our daily life.

Purpose: We undertook this study to find out the recognitions of terminal cancer patients and doctors about advance directives (ADs), of how they would do in non-response medical conditions and whether ADs could be one of medical options for their dying with dignity. Methods: One hundred thirty four cancer patients in the Hospice Unit, St. Vincent's Hospital, and 97 medical doctors in the Department of Internal Medicine, Catholic Medical Center, were asked about ADs, including Do-Not-Resuscitate (DNR), medical power of attorney, living will and medical options. Results: One hundred thirty patients (97%) and 38 doctors (39.2%) were unfamiliar with ADs, however, 128 patients (95.5%), 95 doctors (97.9%) agreed with it. Seventy nine patients (59.0%) and 96 doctors (99.0%) wanted DNR rather then intensive treatments if they were in non-response medical conditions. Eighty four patients (62.7%) and 75 doctors (77.3%) were agreeable to medical power of attorney. One hundred Thirty four patients (100.0%) and 94 doctors (96.9%) did not want medical options to be in terminal conditions, and hoped to die in peace. Conclusion: Most of patients did not know about ADs and how to make it. However, they showed positive attitudes about it. If we advertise it properly, it is highly likely that a large number of cancer patients would make their living wills easily by ADs. Nevertheless, many legal and ethical problems have to be solved. Doctors should engage their patients in an ongoing communication about the end-of-life. Therefore, let the patients have opportunities to plan their own deaths.

A spatially adaptive falter was formulated to imrove PET image qualify and the Performance of the filter was evaluated using simulation and phantom and human PET studies. In the proposed filter. if a pixel was identified as the edge Pixel, the Pixel value was Preserved. Otherwise a Pixel was replaced by the mean of the pixel values weighted by 2:7: 2. A Pixel was identified as the edge Pixel. if it satisfies the following conditions : the number of ADs (absolute difference between center and neighborhood pixels) which is smaller than THl (($pix_max{\times}0.1/log_2(NPM)$, NPM : mean of 6 neighborhood pixels excluding minimum and maximum) is 8-k and the number of ADs which is lager than TH2 ($NPM{\times}0.1$) is k. where k : 2, 3, …, 6. The results of this study demonstrate the superior performance of the Proposed titter compared to Gaussian fitter, weight median filter and subset averaged median filter. The proposed tittering method is simple but effective in increasing uniformity and contrast with minimal degradation of spatial resolution of PET images and thus. is expected to Provide improved diagnositc quality PET images .
