This paper reexamines the formation process of Ch'anggŭk, Korea's musical drama based on p'ansori in the 1930s, focusing on the Ch'anggŭk gramophone records and the repertoire of the Chosŏn Sŏngak Yŏn'guhoe(Korean Vocal Music Association). The paper discussed the achievements and limitations of the Chosŏn Sŏngak Yŏn'guhoe which was at the center of the formation of Ch'anggŭk by examining the activities of the Chosŏn Sŏngak Yŏn'guhoe in the 1930s. The role of 'ipche-chang' and 'narrator' in the Ch'anggŭk gramophone records was seen as Ch'anggŭk imagination that was realized by the members of the Chosŏn Sŏngak Yŏn'guhoe who recognized the 'dramatic space and stage', which is distinct from p'ansori, Korean traditional vocal and percussion music. In addition, the paper discussed the difference and meaning of the concept of 'Sin-Ch'anggŭk' between Seo Hang-Seok and Song Seok-Ha, which is derived from the Ch'anggŭk formation. The performance of stage Ch'anggŭk in the 1930s was a repetition of the discussion that it should reach a point of Kagŭk, music or song dramas. This paper discussed the process of replacing the term 'Ch'anggŭk' with 'Kagŭk' at the time, and examined the way Ch'anggŭk stage was established as a perfect form during the process. The formation of Ch'anggŭk by members of the Chosŏn Sŏngak Yŏn'guhoe could be an important achievement in the history of Ch'anggŭk, but there was no choice but to reveal the limitation in the formal aspect due to the 'refinement' and 'exclusion' according to the cultural policy of Japan. P'ansori musicality was enhanced, but it could not contain the spirit and diversity of the times, so it could be said that there was no choice but to stop as a rudimentary creative imagination of Ch'anggŭk. Ch'anggŭk is a genre that is inherently limited, but the limitation can be overcome over the times, which will be covered in a subsequent paper.

Saekdong is a unique Korean fabric that has been used since ancient times, and it is woven with the plain or satin weave so that vertical stripes appear by various colored warp threads of equal spacing. Saekdong means pleasure, joy, serenity, heavenly blessing, spirituality, wind, and abundance, expressing the optimistic and positive sentiment of Korea's forefathers. This study investigated how ancient Saekdong occurred with meanings. As a research method, this study used literature review and surfing newspapers and photographs, museum and internet search, even from other fields such as earthenware, bronze, and traditional dance. We collected Saekdong and the lifestyles of ethnic Koreans living in China, investigated the Asuka culture of Japan, and the tomb murals of Takamatsu-Chong, which are Baekje and Goguryeo settlement areas. The results are as follows: First, it expresses happy occasion, pleasure, and joy, and expresses a desire for good things to be repeated and lasting. Second, it symbolizes simple beauty, order, equality and harmony of many tribes. Third, Saekdong is life and power which represent a sacred, heavenly, mysterious bird. Fourth, it symbolizes abundance and wealth, rain, wind or fields. Finally, this study showed the brilliance and pride of Korean hanbok through Saekdong. The significance of this study is to examine the symbolism and inherent aesthetic characteristics of Saekdong and to show the unique value and spiritual heritage of the Korean people.

With the changing of social needs and paradigms, citizens are concerned about aesthetic and cultural community gardens from productive urban farms in Korea. It is still difficult, however, to cultivate a beautiful garden with a community to design, install and manage it. Therefore, this study analyzed the community garden design guidelines of other countries to derive the characteristics and implications. The research method analyzed six guidelines for community garden design in the UK, Canada, the USA, Australia and Japan. As a result of the study, most community garden design guidelines are opened freely via on-line service. The guidelines are composed with chronological processes such as intro, site selection, design, construction and maintenance. The introduction section treats definition, purpose, meaning, efficiency and success factors for community gardens. Site selection emphasizes site conditions (soil, light, shadow, water, etc.), landholding and insurance. The design section, however, lacks adequate drawings and case images. These guidelines offer little explanation with few illustrations and sentences. Construction sections explain about plantings, facilities, expense and details. The maintenance guidelines of community gardens contain how to control members, funding, harvesting, pests and plants. In addition, some guidelines include vandalism, organic cultivation methods, recording and advertisement. Lastly, the appendix contains a variety of checklists, administrative documents, guidelines, drawings, and contacts. This study will help understand the trends and characteristics of overseas community gardens design guidelines so as to also supply directions for guidelines to be introduced in Korea.

The purpose of this study was to evaluate the surface change after 15% carbamide peroxide home bleaching to various restorative materials (composite resin [CR], resin modified glass ionomer [RMGI] and glass ionomer [GI]) and to observe the effect of surface condition of the materials on re-staining. Three esthetic restorative materials (Filtek Z250, 3M, USA; Fuji II LC, GC, Japan; Fuji II, GC, Japan) were used in this study. Twenty specimens per material group were made and divided into two groups (bleached and control). The specimens were immersed in coffee after applying bleaching agent. The color change and surface roughness were measured before and after bleaching and after immersion in coffee. The data were analyzed with SPSS 18.0. The results were as follows: 1. The color of all experiment groups was significantly changed after bleaching (p<0.05). RMGI was the greatest value of ${\Delta}E^*$ and ${\Delta}L^*$. GI and CR groups were in ordering (p<0.05). The ${\Delta}a^*$ value was decreased GI, RMGI and CR. RMGI was only significantly decreased in ${\Delta}b^*$ value (p<0.05). 2. The surface roughness before and after bleaching was significantly different on CR, RMGI and GI (p<0.05). 3. After staining with coffee, the value of ${\Delta}E^*$ was increased in GI, RMGI and CR, furthermore GI and RMGI showed significant difference in the bleaching groups (p<0.05). The ${\Delta}L^*$ value of GI and RMGI was significantly decreased. 4. The change of surface roughness after staining was not significantly different in all groups (p>0.05). The maintenance of color stability in esthetic restorations is one of the most important properties. Tooth whitening is for the aesthetic. Therefore, dental professionals should notice to patients about re-staining after tooth whitening. They should give an instruction that how to prevent and which kinds of agents could be stained.

This paper examines how the cinematic representation of the Japanese military "comfort women" stimulates 'imagination' in the realm of everyday life and in the memory of the masses, creating a common awareness and affect. The history of the Japanese military "comfort women" was hidden for a long time, and it was not until the 1990s that it entered the field of public recognition. Such a transition can be attributed to the external and internal chronopolitics that made possible the testimony of the victims and the discourse of the "comfort women" issue. It shows the peculiar status of the comfort women history as 'politics of time'. In the same vein, the cinematic representations of the Japanese military "comfort women" can be found in similar chronopolitics. The 'comfort women' films have shown the dual time frame of the continuity and discontinuity of the 'silence'. In Korean film history, the chronotope of the reproduction of "comfort women" can be divided into four phases: 1) the fictional representations of "comfort women" before the 1990s 2) documentaries in the late 1990s as the work of testimony and history writing, 3) melodramatic transformation in the feature films in the 2000s, and 4) the diffusion of media and categories. The purpose of this article is to focus on the first phase and the third phase in which the issue of 'comfort women' is represented in the category of popular fiction films. While the "comfort women" representations before 1990 were strictly adhering to the framework of commercial movies and pursued the sexual exploitation of "comfort women" history, the recent films since the 2000s are experimenting with various attempts in the style of popular imagination. Especially, the emergence of 'comfort women' feature films in the 2000s, such as Spirit's Homecoming, I Can Speak, and Herstory, raise various questions as to whether we are "properly" aware of issues and how to remember and present the "cultural memory" of comfort women. Also, focusing on the cinematic representation strategies of the 2000s "comfort women", this article discusses the popular politics of melodrama, the representation of victims and violence, and the feature of 'comfort women' as meta-memory. As a melodramatic imagination and meta-memory for the historical trauma, the "comfort women" drama shows the historical, political, and aesthetic gateways to which the "comfort women" problem must pass. As we have seen in recent fiction films, the issue of "comfort women" goes beyond transnational relations between Korea and Japan; it demands a postcolonial task to dismantle the old colonial structure and explores a transnational project in which women's movements and human rights movements are linked internationally.

Purpose: Teeth are generally exposed when people smiling. Moreover, the exposed teeth and soft tissue when smiling becomes an important guideline for esthetically prosthetic restoration. This research is to compare and find out differences of Korean young men's smile living in presence and twenty years ago. Materials and methods: Subjects, 100 young men (50 male and 50 female), were required about several aspects; normally developed physical condition, no psychological or genetic disorders, a fine face with no loss of teeth, no experience in orthodontic or prosthetic treatment, relatively normal occlusion, aged between 20-29. The photos of the subject at rest position and front face when fully smiled were taken three times. 100 photos (50 male and 50 female) were chosen at random from the 240 university students' smile photos taken by Yoon and his colleagues in 1991. By Hulsey's method of measuring smile, several factors; the change of upper lip curvature, the change of the relation between the upper lip and teeth, parallelism between Mx. incisor and lower lip, contact relation between Mx. incisor and lower lip and teeth displayed in a smile, were measured and analyzed. Meanwhile, ten dentists assessed aesthetic evaluation about men and women's smile for twice and recorded and compared smile score. The -test (P<.05) was used to compare the measured value. The difference of smile score was analyzed by t-test (P<.05). Results: The smile score calculated in 2011 (60.22) was higher than that of 1991 (52.80). Among five measurement categories, the noticeable difference was distinguished from two factors; the change of upper lip curvature and contact relation between Mx. incisor and lower lip. Conclusion: The Korean young men's smile has been considerably improved for twenty years. And it is found that the change of upper lip curvature plays an important role, that is, the smile formed with an ascended labial commissure has been increased significantly.

The entry of an aging society and the extension of human life expectancy, the increasing interest in women's social advancement and men's appearance, and the natural interest in K-culture through media media, while receiving worldwide attention, Focus on K-Bueaty. Recently, looking at the occupation of the medical tourism field, in the case of aesthetic medicine tourism such as molding and dermatology, it has gained popularity not only in Asia such as China and Japan, but also in North America and Europe. The first external confirmation of human aging is the wrinkles on the skin of the face. Clean, wrinkle-free, elastic and healthy skin is a desire of most people. Skin condition and condition such as focused ultrasonic stimulation (HIFU: High Intensity Focused Utrasound) and low frequency, high frequency (RF: Radio Frequency), galvanic therapy using microcurrent, cryotherapy using rapid cooling, etc. Depending on the method of management, the effect of the treatment differs depending on the output and the stimulation site, etc., even in the treatment of medical equipment and beauty equipment using the same mechanism. In this research, in order to develop invasive high-frequency dermatological devices using a large number of beauty medical devices and microneedles of beauty devices, the international standards IEC 60601-2 (standards for individual medical devices) and MFDS (Ministry of) We designed and developed a high-frequency output device in compliance with the high-frequency stimulation standard announced in the Food and Drug Safety (Ministry of Food and Drug Safety). The circuit design consists of an amplifier (AMP: Amplifier) using Class-A Topology and a power supply device using Half-Bridge Topology. As a result of measuring the developed high-frequency output device, an average efficiency of 63.86% was obtained, and the maximum output was measured at 116.7W and 50.67dBm.

South Korea had a hard time creating its own image of a nation that formed its identity due to 6.25, Japanese-style rule, division of South and North Korea, and military dictatorship. Recently, Korea has been searching and spreading its identity by creating a Korean wave such as various events and K-POPs. However, since there are still no images and cultural products representing Korea's identity, it is necessary to develop design contents related to native culture and professional cultural product design. Design powers such as France and Japan focus on design projects that can add value to their national design policy projects. Traditional Korean contents also need to be specialized and continuous in image design and research. In this study, five lucky-SubokGangnYeon(long life, happiness and peace), a representative of Korean culture, studied with the most interest in the old and the modern, namely, "Living healthy long." Through the development of cultural product design and the use of design content, I would look forward to presenting the diversity and direction in producing Korea's own design products and images that fit the trend of modern 'age of 100.' Based on images based on special exhibitions related to longevity of the National Folk Museum of Korea, the museum discovers key used features and meanings, studies patterns and patterns, and analyzes design cases applied to modern cultural product design. We also want to look at the direction available through design content, which is a symbol of llong life happiness and peace. First, cultural products have limitations that lack the development of design products, lack of public relations and sales outlets, and lack of awareness of traditional culture, which should precede policy support and awareness reform at the national level. Second, we need to streamline prices that meet the needs of the market. Third, cultural product design and contents related to tradition can be settled and disseminated more easily when traditional design is utilized and distributed mainly on practical stationery and household goods. Fourth, it is necessary to develop contents of various Korean images based on research on Korean cultural history and aesthetic consciousness. Research on the Korean culture of designers should be conducted, not just in the form of figurative images. Fifth, traditional manufacturing methods and materials should be respected by modern times, but modern production products should be developed with economy and durability.
