  • In the past, the Internet connected people together; recently, however it has been extended to the Internet of Things (IoT), allowing all things in the physical world to be connected. We call a new society in which everything is connected through IoT a 'hyper-connected society'. IoT for a hyper-connected society is more than just connecting things to the Internet, it is an infrastructure providing intelligent services without human intervention by connecting things to the Internet using sensors and communication functions, collecting data from connected things, and analyzing and predicting information. Therefore, IoT is a convergence technology that includes not only sensors and communication networks but also big data and AI. This paper examines the short history of IoT, reviews its current trends, and finally, discusses its future direction.

  • This study intends to discover characteristics and methods of retro image wedding dresses by analyzing prior studies about retro characteristics. The characteristics of retro image wedding dresses are as follows: 'Recreative Retro', Trend revival Retro', 'Nostalgic Retro' and 'Remixed Retro'. The expressional characteristics and methods of each character are as follows. The 'Recreated Retro' has been recreated in the wedding dresses worn by celebrities, actresses' wedding dresses in movies, and also in the famous designer's high end wedding dresses. These dresses do not merely duplicate the originals, but also reflect images, which were reproduced by combining modern technology. The 'Trend revival Retro' emerged as a combination of past fashion styles and new trends. It seems to stimulate the customers' reminiscence of past fashion trends and create unique designs through expressing the metaphor or the adaptation of past fashion styles. The 'Nostalgic Retro' started from the discovery of emotional values for something old or the inclination to be attracted to old styles. It has been expressed through design concepts with natural themes. The 'Remixed Retro' is from recombination of Retro elements. It is shown as a new interpretative code which explains how current time blends with different times.

  • In this paper some of the important trends in the spacecraft technology development have been discussed. Trends of higher satellite radiate power, which involves higher TWTA powers and antenna reconfiguration, and Ka-band (30/20 G $H_{z}$) utilization are discussed. Evolutionary trends in satellite communications in general have demonstrated immense potential for meeting the evolving nees and challenges regarding provision of global telecommunications during over past two decades. Their promise for the coming decades as we enter the 21st century may far surpass our imagination. The expansion of fixed satellite service market will depend upon more inelligent spacecraft and a network of more cost effective small earth stations. Radiation hardened microwave analog technologies and high speed digital technologies are getting ready to meet the challenge posed by future markets.

  • Background: Although the breast cancer incidence rate in Japan is lower than in western countries, the age-specific rates have markedly increased in recent years, along with the problems of declining birth rate and an aging population. Materials and Methods: We examined past trends of age-specific breast cancer incidence using data from the Osaka Cancer Registry from 1976 to 2010, and estimated future trends until 2025 based on the changes observed and population dynamics using a log linear regression model. Results: The age-specific breast cancer incidence rate has increased consistently from the 1970s, and the rates have caught up with those of Japanese-Americans in the US. Assuming the increasing tendency of age-specific breast cancer incidence to be constant, the average annual incidence of breast cancer will increase 1.7-fold from 2006-2010 to 2021-2025. Furthermore, the number of patients aged 80 years should increase 3.4-fold. Conclusions: The medical demand for breast cancer care in Japan may increase explosively in the future, particularly among the elderly. We need to prepare for such a future increase in demand for care, although careful monitoring is needed to confirm these results.

  • Purpose: This study aimed to investigate trends in home-visit nursing care by agencies' characteristics under the national long-term care insurance system. Methods: Cochran-Mantel-Haenzel tests were conducted, using data drawn from the nationwide long-term care insurance claim database of the Korean National Health Insurance Corporation from 2009 to 2011. Results: The number of home-visit nursing care agencies has decreased continuously since 2009. There were also similar trends in the total amount of service provided by home-visit nursing care agencies, the number of recipients, the number of employees, and payments. This study showed that there were statistically significant differences in the trends in home-visit nursing care by agencies' characteristics. Despite the overall downward trend, there were some increases in the percentage of home-visit nursing care provided by agencies which were established by individuals, located in large cities, and which combined home-visit care with home-visit bathing. Conclusion: Home-visit nursing care agencies are responsible for providing community-based healthcare services. For past three years, however, they have not been utilized to their full potential. Understanding the trends in home-visit nursing care by agencies' characteristics is important to develop utilization strategies for home-visit nursing care.

  • The purpose of this paper describes the changes of TGV & ICE series' nose shape by increasing train speed and according to the periodical characteristics. As the speed increases, the length of the nose shape trends to lengthen longer. But the nose shape length does not increase as speed improves by optimized nose shape to reduce aerodynamic drag and micro-pressure wave in tunnels. TGV & ICE series' nose shape can be classified into Advanced paraboloid type, Shape-nosed type, Organic double-edged type and Flat-nosed type by the advance research(the changes of Shinkansen vehicle' nose shape) of high speed railway. Because it trends to be diversified and characterized more and more. This paper analyzed and introduced as TGV & ICE series' nose shape by top 2 nation (Germany, France) and high speed railway in the past years(1980-2007) for their railway design trends by new positioning(Advance research).
