This paper argues that news speech entails a distinct intonational pattern from natural speech, effectively reflecting that it primarily focuses on providing new information. We conducted a phonetic experiment to compare the tonal contours between news speech and natural speech, examining the distributions of pitch accents and the overall pitch ranges. We utilized 70 American Press (AP) radio news utterances and 70 natural utterances extracted from TV dramas. Results show that news speech involves 3.38 H*'s (including L+H* and !H*) within an intonational phrase (IP) or intermediate phrase (ip) whereas natural speech, 1.8 in average. The number of IP/ip's per sentence is 3 in news speech, which is shown in the highest rate of 32.07% of the news speech, but it is merely 1, taking up the highest 41.42% in natural speech. Next, declination tends to be prevented in news speech, and the pitch range is much greater in news speech than in natural speech. Finally, a secondary stress syllable is comparatively frequently given a pitch accent in news speech, explicitly distinct from natural speech. These results can be interpreted as stating that news has the particular purpose of providing new information; every content word tends to be given a H* or its related pitch accent like L+H* or !H* because news speech assumes that every word conveys new information. This definitely brings about more IP/ip's per sentence due to a human physiological constraint; that is, more H*'s will cause more respiratory breaks. Also, greater pitch ranges and pitch accents imposed on secondary stress may be attributed to exaggerating new information.

The technology convergence of television, communication, and computing devices enables the rich social and entertaining experience through Smart TV in personal living space. The powerful smart TV computing platform allows to provide various user interaction interfaces like IR remote control, web based control, body gesture based control, etc. The presently used smart TV interaction user control methods are not efficient and user-friendly to access different type of media content and services and strongly required advanced way to control and access to the smart TV with easy user interface. This paper propose the optical wireless communication (OWC) based remote controller design for Smart TV using smart device Flashlights. In this approach, the user smart device act as a remote controller with touch based interactive smart device application and transfer the user control interface data to smart TV trough Flashlight using visible light communication method. The smart TV built-in camera follows the optical camera communication (OCC) principle to decode data and control smart TV user access functions according. This proposed method is not harmful as radio frequency (RF) radiation does it on human health and very simple to use as well user does need to any gesture moves to control the smart TV.
A nutrition education program for teachers and caregivers of the preschool children can be most effective when it is based on a comprehensive needs assessment dealing with sociodemographic factors, dietary habits, and nutrition. The purpose of the present study was to investigate current dietary habits and nutrition knowledge of the teachers and caregivers of the day-care centers. Two hundred forty two teachers and caregivers were administered a questionnaire which was designed to ascertain informations on sociodemographic data, dietary habits and nutrition knowledge. Dietary habits of the teachers were found to be significantly different by sociodemographic variables; breakfast skipping/meal irregularities (age, p=0.011); frequency of snacking (education level p=0.031); preference for salty taste(age, p = 0.000, marital status p=0.038); preference for sweet tarte (age p=0.009); preference for vegetables (income level p=0.050); frequency of eating out (age p=0.028, marital status p=0.001); frequency of coffee drinking (age p=0.019). Daycare center teachers' nutrition knowledge level was found to be less than adequate expecially on nutrients that are liable to be deficient in young growing children and their food sources. Proportions of the teachers who answered correctly to the questions on foods rich in vitamin A, iron content of milk, bioavailability of calcium in plant foods were as low as 20.2%-54.5%. The most frequently used sources of nutrition information were mass media such as TV, radio, newspaper and magazines. Only 2.9% of the subjects reported that they obtain nutrition information from health professionals such as nutritionists/dietitians, physicians, and nurses. These findings are applicable at the planning and implementation stages of various nutrition programs for the improvement of dietary habits and nutrition knowledge of the teachers and caregivers of the daycare centers. Further studies are needed to investigate the effects of teachers' dietary of habits and nutrition knowledge on food habits of young growing children.
Early-type galaxies represent the end point of galaxy evolution and, despite pervasive residual star formation, are generally considered "red and dead", that is composed exclusively of old stars with no star formation. Here, their molecular gas content is constrained and discussed in relation to their evolution, supporting the continuing importance of minor mergers and/or cold gas accretion. First, as part of the Atlas3D survey, the first complete, large, volume-limited survey of CO in normal early-type galaxies is presented. At least of 23% of local early-types possess a substantial amount of molecular gas, the necessary ingredient for star formation, independent of mass and environment but dependent on the specific stellar angular momentum. Second, using CO synthesis imaging, the extent of the molecular gas is constrained and a variety of morphologies is revealed. The kinematics of the molecular gas and stars are often misaligned, implying an external gas origin in over a third of all systems, more than half in the field, while external gas accretion must be shot down in clusters. Third, many objects appear to be in the process of forming regular kpc-size decoupled disks, and a star formation sequence can be sketched by piecing together multi-wavelength information on the molecular gas, current star formation, and young stars. Fourth, early-type galaxies do not seem to systematically obey all our usual prejudices regarding star formation (e.g. Schmidt-Kennicutt law, far infrared-radio continuum correlation), suggesting a greater diversity in star formation processes than observed in disk galaxies and the possibility of "morphological quenching". Lastly, a first step toward constraining the physical properties of the molecular gas is taken, by modeling the line ratios of density- and opacity-sensitive molecules in a few objects. Taken together, these observations argue for the continuing importance of (minor) mergers and cold gas accretion in local early-types, and they provide a much greater understanding of the gas cycle in the galaxies harbouring most of the stellar mass. In the future, better dust masses and dust-to-gas mass ratios from Herschel should allow to place entirely independent constraints on the gas supply, while spatially-resolved high-density molecular gas tracers observed with ALMA will probe the interstellar medium and star formation laws locally in a regime entirely different from that normally probed in spiral galaxies.

The effect of various post-annealing temperature to sputtered Pb(Zr,Ti)$O_3$ (PZT) thin films was investigated. The crystallization process, surface morphology and the electrical characteristics strongly depends on the rapid thermal annealing (RTA). In radio frequency (RF) sputtering methods, there were many papers mostly forcing on the crystal forming and the surface variations with different elements distribution (Pb, Ti, Zr, O) on the surface of the PZT layer. In this experiment, the post-annealing treatment promoted the Pb volatilization in PZT thin film and affected the Ti diffused throughout the Pt layer into the PZT layer. Second ion mass spectroscopy (SIMS) analysis was employed to show that the Pb element in the PZT layer was decreased at the same time the Ti element mass was slight decreased than Pb with increasing RTA temperature. That result prove the content of Pb affect the PZT thin film property.
The brightness of Io's magnetic footprint, an indicator of electromagnetic interaction at the satellite, appears to be strongly connected to the satellite's distance from the plasma equator. As a result, the brightest footprints were detected when Io is near the interception location between the satellite's orbital plane and the plasma equator. However, volcanic activities on Io show strong correlation with the equatorward shift of Jupiter's main auroral oval, consequently causing the disappearance of Io's footprint. The same conclusion was suggested via the observation of Jupiter's hectometric radio emission, called HOM, which closely corresponds to Jupiter's auroral activity. The plasma environment near the Jovian satellites was found to vary significantly at different observational epochs. The electron density increased by approximately a factor of three from the Voyager epoch (1979) to the Galileo epoch (1995), while the electron density was found to be significantly higher (~ 5 times) in the Cassini epoch (2001). In this current study, the magnetic footprints were clearly brighter ten years ago (from peak brightness in 1998-2001) than the footprints detected in 2007. For volcanic activities on Io in 2007, there are two clear activities in February and late May. The magnetic footprint appeared to be dimmer in March 2007, expected to be the result of volcano activities in Feb 2007. However, the magnetic footprint brightness in June appeared to be slightly brighter than the footprints observed in May. The reason could be the time delay between the brightening of the sodium nebula on approximately May 31st and, a while later, the enhancement of flux tube content peaking on approximately June 5th. On the other hand, Io's magnetic footprints were observed during June 1st - 10th when they may not yet have been affected by the increase in mass outflow due to the increase of plasma density.
Despite continuous efforts to redraw the boundaries between art and culture, the conventional concept of originality has persisted in approaches to the practice of contemporary art. In the discourse of originality, various forms of lesser arts that employ the method of replication have been referred to as kitsch, or "rear-guard," the opposite of avant-garde. This categorization points to the contested issue regarding the oppositional relation between modernism and mass culture. With its easily accessible content and financial affordability, mass culture has become both an irresistible attraction and a most powerful threat to modernism. This threat has instigated a discursive system that has situated mass culture as a cultural other of modernism. Taking the marginalized category of kitsch as the area of contention, this paper examines a discursive repression of kitsch. It analyzes the conceptual framework that defends originality and autonomy in art and, conversely, degrades kitsch as an inferior and dangerous cultural category. Greenberg'S concept of kitsch as a by-product of industrialization evolved into the criticism that advocates the autonomy of art. The Frankfurt School scholars, particularly Theodor Adorno and Max Horkheimer, practiced comparable cultural critiques. Focusing on mass culture such as film, radio, and television, instead of art works, they critically analyzed the system of mass culture and theorized the negative implications of the ubiquitous presence of kitsch. Some critics, on the other hand, perceived the growth of mass culture as opening possibilities in cultural development. Walter Benjamin and Harold Rosenberg asserted the socio-cultural dynamics of mass culture underlining the potential for continual transformation in reality and in the subject. They acknowledged that technological advances changed the condition of creation and enabled unmediated interactions between media. By scrutinizing conflicting views on kitsch, this paper intends to reassess arts that draw "the forces of the outside."

The existing digital signage systems inside the elevators are a lack of tailored contents appropriate to the space and environment inside or outside the elevators. Also, they almost impossible to flexibly respond to various contents disclosure according to the demand of the consumers or the elevator markets. Therefore we design and implement an IoT(Internet of Things)-based smart digital signage system for the safety of elevator passengers.. In order to provide IoT-based information to the smart digital signage within the elevator, we propose an IoT system as a set-top box with gyroscope sensor, acceleration sensor, RFID(Radio-Frequency Identification), fine dust sensor, etc., which processes various data collected by the sensors and provides the elevator passengers with various tailored contents such as elevator driving information, environmental information inside and outside the elevator, and disaster information in addition to simple advertisement information. The proposed IoT system is a set-top box that operates the smart digital signage and has an independent information control processor based on the IoT sensors that do not depend on the elevator control system. For the proposed smart digital signage, it supports an operating system that is independent of the elevator driving service as well as the media service. So the smart signage system has a characteristic that it does not depend on the elevator control system since it is a stand-along IoT-based information control system. With the proposed system providing intuitive content for the surge, steep descent, and radical movements of an elevator due to an emergency situation, the elevator passengers should be able to recognize the situation quickly and respond accordingly. In the near future, the proposed system will expand the market of digital signage applied in conjunction with the development of contents in the disaster, safety and environment fields, and expect expected to revitalize related industries associated with signage.
Purpose: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident. Methods: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data. Results: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities. Conclusions: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.
NiO thin films were deposited by radio frequency magnetron sputtering on glass substrates. The processing variables of the oxygen content, sputtering power, and pressure were varied to investigate the electrical properties and surface morphology of NiO films. It was found that the resistivity of NiO films at $1.22{\times}10^2{\Omega}cm$ (2.5% $O_2$ in Ar gas) was greatly reduced to$ 2.01{\times}10^{-1}$${\Omega}cm$ (100% oxygen) under a typical sputtering condition of 6 mTorr and 200 watts. In an effort to observe the resistivity variances, the sputtering power was varied from 80 to 200 watts at 6 mTorr with 100% $O_2$. However, the resistivity of the NiO films changed in the range of $10^{-1}-10^{-2}$${\Omega}cm$. The dependence on the sputtering power was therefore found to be weak in this experiment. When the sputtering pressure was changed from 3 to 60 mTorr at 200 watts with 100% $O_2$, the resistivity of the NiO films showed the lowest value of $5.8{\times}10^{-3}$${\Omega}cm$ at 3 mTorr, which is close to that of commercial ITO films (${\sim}10^{-4}$${\Omega}cm$). As the sputtering pressure increased, the resistivity also increased to 4.67 cm at 60 mTorr. The surface morphology of the NiO films was also checked by Atomic Force Microscopy. It was found that the RMS surface roughness values ranged from 0.6 to 1.5 nm and thtthe dependence on the sputtering parameters was weak.
