Senior business has been paid attention due to rapid global aging and baby boomers turning 60. However, senior business is not successful as expected because of a lack of understanding of consumers and small size of Korean domestic market. Understanding of senior consumers and overseas markets and providing attractive product and service contents needs to overcome the current challenges. Therefore, this study explores and compares consumers of different generation and different countries. We employ consumption value theory and analyze which consumption values are perceived strongly by each four group(Korean consumers in their 20s, Korean their consumers in 50s, Chinese consumers in their 20s, and Chinese consumers in their 50s). We conducted online survey to compare consumption values among samples of consumers in two countries: Korea and China. There are forty survey instruments in twelve consumption values. The results can be used to develop a strategy for planning, developing, distributing, and promoting product and service contents which consumers, in particular baby boomers, have a strong intention to purchase it.

Tourism is an attractive field of industry to many countries due to its strong potentials in increasing employment rates as well as improving the national image. The positive effect of the tourism on the national economy and globalization has been recognized in Korea. A multilateral effort has been made in order to develop its tourist industry. Therefore, it is necessary to analyze the patterns of tourism demand in Korea. The present study analyzes and demonstrates the effects of a nation's characteristics on tourism demand. The study model was based on factors that affected tourism demand, especially emphasizing on the economic size, distance, national income, and language differences from the mother country. In particular, this study highlights the effects of economic relations between the countries and their exchange rate on tourism demand. In summary, this thesis demonstrates that actual national and international panel data enhance the credibility of the research and precisely determine factors that have a direct influence on tourism demand. A corresponding strategy of development and products are required as most tourists show the preference in advanced nations.

In this article, concepts, types, and aspects of geological heritage with increasing interests as utilization as tourist attractions domestically and internationally are introduced, and the characteristics of the interpretive facilities for geological heritages in western Australia, one of the most famous geotourism areas, are considered. Based on this, the potential geotourism for the Korean Cretaceous geological heritages including dinosaur fossil sites is discussed in diverse aspects including academic values, academic and tourism infrastructures, characteristics of geotourists, systematic devices for conservation of geological heritage, economic value, and sustainability as tourist attractions. Although the Korean Cretaceous geosites are not quite competent in their scale or diversity when compared to world-class geosites, convenient access, world-class unique geographical characteristics of each geosites, and relatively cheaper travelling expenses seems to be able to give the geotourism of the South Korean Cretaceous geosites a competitive edge, attractive for international and domestic tourists seeking unique experience of 'Age of dinosaurs' for short periods with easy access from metropolitan areas and low costs. Likewise, the development of geotourism for the Korean Cretaceous geosites can revitalize the geotourism industry in South Korea, contributing to the growth in job opportunities, including students majoring in geological sciences at University.

Portable low-cost magnetic resonance imaging (MRI) systems have the potential to enable "point-of-care" and timely MRI diagnosis, and to make this imaging modality available to routine scans and to people in underdeveloped countries and areas. With simplicity, no maintenance, no power consumption, and low cost, permanent magnets/magnet arrays/magnet assemblies are attractive to be used as a source of static magnetic field to realize the portability and to lower the cost for an MRI scanner. However, when taking the canonical Fourier imaging approach and using linear gradient fields, homogeneous fields are required in a scanner, resulting in the facts that either a bulky magnet/magnet array is needed, or the imaging volume is too small to image an organ if the magnet/magnet array is scaled down to a portable size. Recently, with the progress on image reconstruction based on non-linear gradient field, static field patterns without spatial linearity can be used as spatial encoding magnetic fields (SEMs) to encode MRI signals for imaging. As a result, the requirements for the homogeneity of the static field can be relaxed, which allows permanent magnets/magnet arrays with reduced sizes, reduced weight to image a bigger volume covering organs such as a head. It offers opportunities of constructing a truly portable low-cost MRI scanner. For this exciting potential application, permanent magnets/magnet arrays have attracted increased attention recently. A magnet/magnet array is strongly associated with the imaging volume of an MRI scanner, image reconstruction methods, and RF excitation and RF coils, etc. through field patterns and field homogeneity. This paper offers a review of permanent magnets and magnet arrays of different kinds, especially those that can be used for spatial encoding towards the development of a portable and low-cost MRI system. It is aimed to familiarize the readers with relevant knowledge, literature, and the latest updates of the development on permanent magnets and magnet arrays for MRI. Perspectives on and challenges of using a permanent magnet/magnet array to supply a patterned static magnetic field, which does not have spatial linearity nor high field homogeneity, for image reconstruction in a portable setup are discussed.

Lips have a defect in maintenance of moisture due to their thin layer. As aging progresses, lips lose volume and redness, and become wrinkled. Fat grafting and filler surgery have been used to achieve attractive lips, but little research has been reported to develop better materials to replace the present methods. Recently, a study suggests that the increase of adipocyte number can be enhancing the expansion endogenous fat. In previous study, we identified that the efficacy of Magnolia officinalis bark extract (MOBE) was effective on the induction of adipogenic differentiation. In this study, we confirmed that MOBE enhanced the differentiation of human adipose-derived stem cells on the fat mimic 3D structure built by 3D bioprinting method From further experiments in human, we established a method to quantify the severity of lip wrinkle by measurement of standard deviation of gray value using Image J software. Finally, we found that topical treatment with 1% MOBE formulated lip balm significantly improved the lip wrinkle after using for 12 weeks. In conclusion, these findings suggest that MOBE has great potential, as a cosmetic ingredient, to reduce the lip wrinkle through the effect of promoting adipogenic differentiation.

The purpose of this study is to propose a strategy for creating an advertisement for Corporate Social Responsibility(CSR) based on the strategy of selecting an advertisement model in order to efficiently execute the advertisement of CSR. Data were analyzed by regression analysis. The results of this study are as follows: First, it is found that the value-relevance factors of the model are important regardless of the theme of CSR. In the economic field, the reliability of the model is important. But, the attractiveness of the model was more important in the environmental field. Second, it is effective to select a model with high value-relevance when selecting CSR advertising model. But, in the case of an expert, it is effective to select not only value addition, but also attractive and reliable models. Third, when producing CSR ads using emotional messages, it is important to consider the value and reliability of the advertising model. But, it is important to select the model considering the importance of the value and attractiveness of the advertisement model when producing the CSR advertisement using the informational message. It was found that it is very important to select a model that has a high relevance to the image of the social responsibility subject and the advertisement model when producing the social responsibility advertisement.

In spite of a few numbers of Hyangga that is handed down today, Hyangga has diverse and abundant contents. So it is possible to survey Hyangga as a journey literature of the middle age. On this purpose we can inquire into the Hwarangs' group journey, because the Hwarang was one of the main enjoying group of Hyangga. Hwarangs' group journey shows many aspects. They made a journey for the public purpose like a tour of inspection of people's daily life and the fortresses of the country's peripheral areas. Also, they made a journey for personal purposes like enjoying the attractive view of the mountains and rivers or seeking pretty girls outside of the palace. On these journeys, Hwarang made and enjoyed Hyanggas. Among Hyanggas that remains today, Hyeseongga and Cheoyongga have a direct relation to Hwarang's journey. Hyeseongga was made to eliminate the calamities that occurred at the time of the start of a journey. It is expressed in this poem that Hwarang could take a peaceful trip with the condition that the celestial objects shed light on the earth path. As such, the trip becomes a sacred ceremony. Cheoyongga reflects the fact that the foreigner Cheoyong became Hwarang and toured the streets of Seorabeol, the capital of Shilla. The Cheoyong's bitterness of broken love is expressed in this poem. SongSadahamga and MoJukjirangga come under a broad category of Hwarang's journey literature. SongSadahamga is a farewell poem for Hwarang who leaves to fight on the battlefield. It was universal to make a journey for the fighting of a battle in Shilla period, so many Hyanggas would be made under those situations. MoJukjirangga has the content of Hwarang's trip for saving his follower who was taken by another senior. It expresses the intimate relationship between Hwarang and the follower. Though the words of the song have not been remained, Hyeongeumpogok, Daedogok, and Mungungok were created on the way of Hwarang's journey. These seem to be a series poems which have the proper characteristic features of the Hwarang's journey literature. In these poems, the king's open mind and liberal political views are reflected. In short, Hwarang created and enjoyed Hyanggas on the way of their journey, so Hyangga has the features of journey literature in Korean middle ages.

The wind turbines with a rated capacity of 50kW or less are generally considered as small class. Small wind turbines are an attractive alternative for off-grid power system and electric home appliances, both as stand-alone application and in combination with other energy technologies such as energy storage system, photovoltaic, small hydro or diesel engines. The research objective is to develop the 50kW scale wind turbine blades in ways that resemble as closely as possible with the construction and methods of utility scale turbine blade manufacturing. The mold process based on wooden form is employed to create a hollow, multi-piece, lightweight design using carbon fiber and fiberglass with an epoxy based resin. A hand layup prototyping method is developed using high density foam molds that allows short cycle time between design iterations of aerodynamic platforms. A production process of five blades is manufactured and key components of the blade are tested by IEC 61400-23 to verify the appropriateness of the design. Also, wind system with developed blades is tested by IEC 61400-12 to verify the performance characteristics. The results of blade and turbine system test showed the available design conditions for commercial operation.

This study examined the fantasy drama series Tale of the Nine Tailed, which uses the world view of a folktale and adopts the motif of reincarnation. Tale of the Nine Tailed adopted a cyclical structure where the fate of the past repeats itself in modern life. The traditional Korean folktales that are used in the drama series all share the same topic, but they also vary slightly by region or era. Tale of the Nine Tailed changes people's common negative perception of the nine-tailed fox. First of all, the series portrays the nine-tailed fox as an attractive male, rather than a seductive female. It also incorporated various episodes to tell the story of a heroic nine-tailed fox that uses supernatural powers to save not only those whom he loves, but also the general public. Furthermore, it was a new attempt to bring the nine-tailed fox together with other characters from different folktales into a story to make different world views merge into one. This study analyzes how the narrative structures of traditional folktales are adapted and changed in fantasy drama series, and it explains how various types of result can be created from the storylines of traditional folktales and the imaginations of the authors.

In this study, an augmented reality-based make-up tool was built to analyze the user's face shape based on face-type reference model data and to provide virtual makeup by providing face-type makeup. To analyze the face shape, first recognize the face from the image captured by the camera, then extract the features of the face contour area and use them as analysis properties. Next, the feature points of the extracted face contour area are normalized to compare with the contour area characteristics of each face reference model data. Face shape is predicted and analyzed using the distance difference between the feature points of the normalized contour area and the feature points of the each face-type reference model data. In augmented reality-based virtual makeup, in the image input from the camera, the face is recognized in real time to extract the features of each area of the face. Through the face-type analysis process, you can check the results of virtual makeup by providing makeup that matches the analyzed face shape. Through the proposed system, We expect cosmetics consumers to check the makeup design that suits them and have a convenient and impact on their decision to purchase cosmetics. It will also help you create an attractive self-image by applying facial makeup to your virtual self.
