To find out the suppressive effect of natural extract Curcuma xanthorrhiza on $IL-1{\beta}$ and MMP-2 derived from periodontal ligament cells through in vitro study and to confirm its effect on plaque and gingivitis through clinical study, Curcuma xanthorrhiza containing toothpaste was used and following results were produced. 1. In vitro study, type IV collagenase MMP-2 production was inhibited dose-dependently in the group treated with Curcuma xanthorrhiza compared to the control group. 2. In vitro study, the production of $IL-l{\beta}$ which is one of the inflammatory mediators associated with periodontitis was inhibited dose-dependently in the group treated with Curcuma xanthorrhiza. 3. On the third week, the plaque index of the groups treated with or without Curcuma xanthorrhiza containing toothpastes were both increased significantly compared to the baseline(p<0.05). 4. On the third week, the gingival index of the group treated with Curcuma xanthorrhiza containing toothpaste was not significantly different from baseline. However, the group treated without Curcuma xanthorrhiza containing toothpaste showed a significant increase of gingival index at shielded area(p<0.05). 5. The gingival index of the group without Curcuma xanthorrhiza containing toothpaste showed a significant increase in the sites without tooth brushing when compared to sites with tooth brushing(p<0.05). However. there was no significant difference for the group with Curcuma xanthorrhiza containing toothpaste in sites either with or without tooth brushing. 6. The Bleeding on probing for the group without Curcuma xanthorrhiza containing toothpaste showed no significant difference even when tooth brushing was done. However, for the group with Curcuma xanthorrhiza containing toothpaste, bleeding on probing was significantly reduced compared to baseline when tooth brushing was done(p<0.05).

The purpose of this study was to evaluate the efficacy of the Sonicare $Elite^{(R)}$ power toothbrush in plaque removal and reduction of gingivitis from hard-to-reach sites of the moderate periodontitis compared to regular manual toothbrush in 12 week follow-up. 82 subjects with incipient to moderate periodontitis were randomly assigned to use either the manual or sonic brush, instructed in its use, and asked to brush 2 times a day for 2 minutes. Plaque scores were taken at baseline, 1, 4, 12 weeks using Silness & $L\ddot{o}e$ plaque index and gingival inflammation was assessed by the $L\ddot{o}e$ & Silness gingival index. The results were as follows. 1. The Sonicare $Elite^{(R)}$ power toothbrush showed a significant reduction(p<0.0001) of the plaque(Silness & $L\ddot{o}e$) and gingival inflammation(Loe & Silness). 2. The Sonicare $Elite^{(R)}$ power toothbrush showed a significant better reduction of plaque and gingivitis(p<0.05) than the manual toothbrush after 1, 4, and 12 weeks. 3. The Sonicare $Elite^{(R)}$ power toothbrush demonstrated a significant reduction(p<0.0001) of the plaque in interproximal sites(p<0.0001), buccal sites(p<0.0001) and the lingual sites(p=0.00l8) of the teeth. 4. The Sonicare $Elite^{(R)}$ power toothbrush demonstrated a significant reduction(p<0.0001) of the gingival inflammation in the interproximal sites(p<0.0001), the buccal sites(p<0.0001) and the lingual sites(p<0.0001) of the teeth. The results of this study support the findings that Sonicare $Elite^{(R)}$ power toothbrush has a great potential to remove the plaque and resolve the gingival inflammation during the period of 12 week.

Purpose: Developments in micro/macrostructures of implants and surgical techniques brought out stable outcomes of implant dentistry. The aim of this study was to evaluate the distributions of implant patients, the types of implanted sites, and the success or survival rates of various implant systems and to analyze the implant placement done at each specificintraoral site and situation. Materials and Methods: The data of dental implantations collected between 1992 and 2006 at the Department of Periodontology in 00000 University Hospital were analyzed. Results: 1. Largest part of the patients were at the age of 40s and 50s in bothgender who lost their teeth mostly by periodontaldiseases and caries at the posterior intraoral sites as major ones. Bone densities of type II(mandible) and III(maxilla) were likely to be seen with quantity of type B. Lengths of the implants between 10 and 15 mm and wide platform took the largest part. 2. Survival rates of $Implantium^{(R)}(98.8%)$, $Xive^{(R)}(100%)$ and ITI $TE^{(R)}(100%)$ were high when $Frialit-2^{(R)}$ showed 82%(poor bone density area) or 87.2%(combined with additional therapy). $IMZ^{(R)}$ had lowest cumulative survival(67.5%) and success rate(49.4%) amongst all. 3. Replacement with 2 wide or 3 regular platforms showed no significant differences in survival rate and marginal bone loss atmandibular posterior area. In single restoration of mandibular second molar, 5-year success rate of machined surface $Br{\aa}nemark^{(R)}(70.37%)$ was lower than that of rough surface $ITI^{(R)}$ SLA(100%). 4. Replacement of single tooth in anterior area showed high survival rate of 94.5%. 5. The success rates of $Br{\aa}nemark$ Ti-Unite and ITI SLA at posterior maxilla with poor bone density both showed stable outcomes. 6. 10-year cumulative survival rate of implants with maxillary sinus augmentation by lateral window approach appeared to be 96.60%. Low survival rate(75%) was shown when there were more than two complications combined. Height of grafted bone remained stable above the implant apex. Conclusions : Rough surfaced implants showed stable outcomes in most of the situation including poor bone density and additional therapy combined.

Tiffany & Co. had been recognized so highly in Korea even before its official advance to the country in 1991 that a successful jewelry company was called ‘Korean Tiffany’. The purpose of this study was to explain how American brand Tiffany had been spread and recognized among Korean people by analyzing related articles and advertisements during the period from the Liberation to the 1989. The research method used in this study was the articles of newspapers and relevant literature. This is the result that, with the run of movie ‘Breakfast at Tiffany’s in Korea in 1962, the trade name and trademark of Tiffany were used illegally not only by jewelry traders but also by other businesses. Other luxury jewelry brands in the same period could not enjoy indirect advertising and spillover effects as good as Tiffany. As a result, a successful jewelry company was called ‘Korean Tiffany’ in 1989, and the expression is still valid in the country.

한국 현대도예의 회화적 표현에 관한 고찰

홍지연 ( Hong Ji Youn ) 한국기초조형학회 2018 기초조형학연구 Vol.19 No.2

회화와 도예는 창조를 근본으로 하여 물질적으로 표현 되어지는 예술분야 중 하나이다. 현대에 이르러 예술의 영역은 광범위해지고 있으나, 모든 예술은 하나로 이어져 있다. 그 중에서도 회화와 도예는 역사적으로도, 각 장르의 표현의 방법으로도 밀접한 관계를 지니고 있다. 그리하여 본 연구에서는 회화와 도예의 상관관계와 접목성을 확인하고, 한국 현대도예에서의 회화적 표현을 되짚어봄으로써 두 분야의 밀접한 관계에 대해 고찰하여 한국도예에서 회화적 표현의 무한한 발전가능성을 확인하고자 하였다. 본 연구의 2장에서 그 두 분야에 대한 관계를 고찰해보고, 3장에서는 한국 현대도예의 회화적 표현이 어떠한 양상으로 이루어지고 있는지 시기별로 살펴본 후 그 결과로 앞으로 한국 현대도예가 나아가야 할 근본적 방향을 제시한다. 첫째, 세계화로 나아가는 현대시대에는 작가의 개념적 표현이 중시되고, 과거의 불에 의한 우연의 효과보다는 계획된 디자인과 감성표현이 작업에 반영되어 도예가들은 자신만의 조형언어를 이용하여 이미지를 구체화하는 회화적 표현으로 발전시킬 수 있다. 둘째, 회화적 양상을 띤 도예작품으로 인해 도예의 가치성과 예술성을 인정받는데 이바지 할 수 있으며, 회화적 양상을 띠는 작품도 다양한 방향으로 발전시킬 수 있음을 확인하였다. 마지막으로 패턴과 장식적 표현 및 이미지차용, 다양한 색의 사용, 전통회화의 입체화, 흙의 물성을 이용한 회화적 표현, 추상적 도자조각 등 다양한 양상으로 보여 지는 도예의 회화적 표현을 알 수 있었다. 나아가 도예를 회화의 개념으로만 인식하거나 회화를 도예표현의 하나의 수단으로써 인식 또는 회화적 느낌의 수단으로 인식하는 것이 아닌 세계의 경향에 따라 한국의 정신을 가지고 한국 고유의 현대적 재해석을 통한 진정한 접목으로써 예술적 한국 현대도예로 발전되어 가길 기대한다. Paintings and ceramics are the genres of art materially expressed based on creation. In modern days, diverse genres of art are not only expanding, but also converging. Notably, paintings and ceramics have been closely related to each other throughout the history of art as the methods of expression. Hence, this study confirms the correlation and connection between paintings and ceramics, and considers the painterly expressions in Korean contemporary ceramics to ponder upon the intimate relationship between the two genres and ultimately to establish the infinite potential of the painterly expressions in Korean ceramic art. Chapter 2 of this paper reviews the relationship between the two genres. Chapter 3 examines the aspects of painterly expressions implemented in Korean contemporary ceramic art by period and suggests the following integral directions which Korean contemporary ceramic art should pursue. First, in the global modern world where artists’ conceptual expressions are valued, rather than the classical accidental effects dependent on fire, planned design and emotional expressions are reflected in artworks. In the same vein, ceramists can draw on their own formative language to formulate and develop specific images with painterly expressions. Second, painterly ceramic works are conducive to ceramic art’s value and aesthetic quality being recognized. Also, the works of ceramic art assuming painterly aspects can be developed further in various ways. Finally, the painterly expressions in ceramic arts are characterized by diverse aspects including patterns, ornamental expressions, appropriation of images, use of multiple colors, 3D stereogram of traditional paintings, painterly expressions utilizing the properties of earth, and abstract ceramic sculpture. In brief, Korean contemporary ceramic art will evolve further by following the global trends while holding on to the spirit of Korean art and attempting an original Korean modern reinterpretation and connection, not by perceiving ceramic art just as a painterly concept or paintings as a means of expressions in ceramic art or a painting-like means.

Chinese styles worked as a source of new inspiration in the history of European arts and designs, and their influence has been recurring continuously until now. In particular, the Chinese mode that began to rose in Europe in the early 20th century provided new energy to modern European design and triggered the advance of modernism. The present study examined the influence and meaning of Chinese culture by analyzing Chinese styles observed in European gem-set craft in the early 20th century in terms of material, design motive and color. The influence of Chinese styles was characterized by the use of materials such as jade, enamel and mother of pearl, and design motives such as Chinese figure and scenary, dragon and Buddhism. In terms of color, black - white - green - blue - red was a representative color combination and in which boldly mixed each other. Chinese styles, which originated with the fusion of European and Chinese culture, brought various changes to gem-set craft in Europe during the early 20th century. Moreover, they did not die out, but the cultural fusion has laid the ground of new aesthetics for comtemporary gem-set craft.

포스트모더니즘적 관점에서 본 민화와 우키요에의 비교연구

홍지연(Hong Ji youn) 한국조형디자인학회 2017 조형디자인연구 Vol.20 No.1

모든 예술과 사조들은 과거로부터 반발하거나 계승하고 또한 차용하면서 발전되어 나아간다. 포스트모더니즘 또한 모더니즘의 연속인 동시에 부정으로 리얼리즘의 객관적 재현미학에 반대하는 것이다. 민화나 우키요에나 사실적인 부분을 회화로 담아내고는 있지만 구도나 크기에서는 리얼리즘 회화와는 다른 방식을 취하고 있다. 이는 논리적 사회문화에서 감각적 사회문화로의 변화를 반영하여 담아내고 있다. 포스트모더니즘이 자본주의 소비문화와 대중예술에 기반을 두고 있는 점에서 대중적 회화인 민화와 우키요에와 같은 맥락으로 볼 수 있으며, 그 특성들도 포스트모더니즘적 관점에서 유사한 미학적 개념을 지니고 있음을 알 수 있다. 민화는 우리민족의 독창적 예술성을 가장 잘 나타내고 있으며, 민화 그림속의 무늬들은 각각의 의미와 상징을 지니고 있어 옛 사람들의 생활과 생각들을 알 수 있다. 또한, 민화는 인간내면의 무의식 세계를 표현한다는 점에서도 매우 조형적인 특징을 지니고 있다. 우키요에는 정토성불(淨土成佛)하는 불교적 사상에서 출발하여 현세를 잘 살아보자는 향락주의적 인생관을 보여주려 했던것에 기인해서 지극히 일상적인 화풍으로 사람들의 생활상을 감각적으로 풀어낸다. 기존의 틀과 관습을 타파하고자 하는 시대의 흐름에 따라 장식적인 요소가 강한 화려한 색채와 기존의 방식과 다른 구도, 대담함 등의 혁신적인 요소가 유럽인들에게 매력적으로 다가갔을 것으로 여겨진다. 함축적이면서도 동양적인 정서를 반영한 표현으로 독특한 아름다움을 지닌 민화와 우키요에에는 대중성, 상징성, 다양성, 장식성, 일상성 등의 특징들을 볼 수 있다. 민화와 우키요에의 평범하면서도 감각적인 화풍은 이제까지 답습되어온 관념화된 전통적 동양화풍의 틀에서 벗어나 신선한 사고의 전환을 가져다주게 된 화풍이다. 이 두 소재를 포스트모더니즘의 여러 요소 중에 대중성과 조형성을 중심으로 비교연구 함으로써 우리 민화의 가치를 재발견하고, 이를 통해 세계화의 무한한 가능성을 인식하여야 한다. All arts and trends develop while resisting against the past, and inheriting or borrowing from it. Postmodernism also is a continuation of modernism while opposing against objective representation esthetics of realism. Although folk painting and Ukiyo-e represent realistic parts in the form of painting, they take different methods from realism painting in composition or size. This reflects a shift from logical social culture to sensible social culture. Postmodernism can be seen in the same context as popular painting such as folk art and Ukiyo-e in the sense that it is based on consumption culture of capitalism and popular art. Characteristics of folk painting and Ukiyo-e have a similar esthetic concept from the perspective of postmodernism. Folk painting represents the unique artistry of Korean people more than anything else, and each pattern in folk painting has its own meaning and symbol that enable us to have a glimpse of life and thought of our ancestors. Also, folk paining has a good deal of plastic characteristics in the sense that it represents the unconscious inner world of human beings as well. Ukiyo-e, which began from a Buddhist thought of attaining Buddhahood in Pure Land that gave rise to a hedonistic outlook on life, describes everyday life of people sensibly in an extremely matter-of-fact fashion. Such innovative elements as brilliant and fanciful colors, composition that is different from existing styles, and boldness which reflect the current trend to get out of existing conventions and frames must have appeared attractive to Europeans. In folk painting and Ukiyoe containing a unique beauty which reflects connotative and Oriental sentiment, one can see characteristics of popular appeal, symbolism, diversity, fanciness, and everyday life. Plain and sensitive fashion that characterizes folk painting and Ukiyo-e is a style of painting that enables us to get out of a conceptual tradition in Oriental painting for a refreshing shift in our thinking. Accordingly, an attempt was made in this thesis to rediscover the value of Korea’s folk painting by conducting a comparative study of these two subjects in the context of postmodernism and to recognize the unlimited potential of folk painting for globalization through it.
