Seochon('West Village') is located in the west side of Gyeongbokgung(Gyeongbok Royal Palace) inside the old city wall of Seoul. Seochon has beautiful scenic view surrounding Mt. Inwang and has been known as the representative historical and cultural landscape region in Korea that historical and cultural resources are rich. But when the figure of Seochon which has repeated the changes with the ones of the times is considered, values of beauty of natural landscape that Seochon had and its own placeness have not been gradually recognized as it has been swept away in logic of the development on the strength of economics. This study tries to examine the original form of landscape on Seochon which can be the standard of landscape change, the causes and process of its change and possibility to conserve and restore it to recognize potential value about historical culture of Seochon landscape and conserve and protect it. For this, this study compared and analyzed literature including poems and Yusangi, paintings and names of the scenery of the seasons as the landscape texts with the current status. The study result has found that Pilwundae should rehabilitate cultural assets to secure the prospect right and protect neighboring bedrock, Suseong-dong should expand the restoration areas focusing on the projects to make parks which are now being restored, Cheonghwigak and Cheongpunggye areas should restore waterways including historicity which is connected to figures and Seshimdae and Baekun-dong green zone should set the protective area for conservation.

Alcohol content, which is an important standard for Takju, a traditional multiple parallel fermentation liquor called makgeolli, is a factor that can affect the flavor. For alcohol content analysis, the distillation/hydrometry technique is mainly used. In this study, we analyzed the alcohol content of 14 commercially available Takju by the distillation/hydrometry technique and the improved GC method, respectively, after verifying the reliability of improved GC method. The precision and accuracy of the GC method were satisfactory, and LOQ and LOD were evaluated as 0.5% and 0.1% of ethanol contents, respectively. Among the three Takju exceeding the labelled alcohol content ±1, one Takju was quantitated as alcohol content 9.9% (by GC method) and 10.1% (distillation/hydrometry technique) exceeding labelled 6.0%. It was within the analytical error range of alcohol content for other two Takju, where the alcohol contents were exceeded -1.1%. The average precision (%RSD) of 14 Takju analyzed by the distillation/hydrometry technique (36.2%) and the GC method (12.8%), confirming that the GC method was better than the other. The improved GC method was evaluated to be effective in managing and improving the alcohol content standard of Takju with the wide range of alcohol content.

Due to the increasing influence of the Korean Wave, traditional themes are emerging to the forefront of performance content development, emphasizing the necessity of applying the art of storytelling to the creative process. The purpose of this research is to examine the differentiated costume design of the Pansori ballet "Dokkaeba! Dokkaeba!," developed through the implementation of storytelling in its performance creation process. Choreographers, writers, and costume designer collaborated throughout the storytelling process from planning to content creation. This resulted in a clarified depiction of the Dokkaebi as divine beings with transcendental powers who are simultaneously friendly and familiar entities, often appearing in the form of humans and objects. Accordingly, the costume design based on this collaborative storytelling deliberately avoided the appearance of Dokkaebi reminiscent of 'Kwimyeonwa' or Japanese 'Oni', typically expressed with horns or decorations, and instead implemented novel design elements, such as fusion Hanbok with a variety of dimensionally aesthetic accessories, meaningful color contrast in modern clothing, textural elements indirectly expressing character and transmogrification, and daily clothing attire to illustrate the humanized Dokkaebi. Therefore, this study seeks to contribute to the production of new performance art showcasing the Dokkaebi by identifying the diversity of expression and direction within costume design.

본 연구는 저탄소 녹색성장의 국가 정책에 맞추어 주류 제조과정에서 발생하는 생전분발효 부산물인 주박(酒粕, 술지게미)을 펠릿화(pellet) 하는 것이 목적이다. 주류 제조과정에서 발생하는 주박을 100g당 물 100ml 비율로 섞어 충분히 반죽 후 녹즙기로 압축 성형화 하는 과정을 대신 하여 주박을 뽑았다. 이 주박을 온열 건조기에서 20시간이상 건조 시키면 완성이 된다. 주박펠릿은 폐기물을 재활용한 것이기 때문에 열량-가격대비를 비교해 보았을 때 등유 8950kcal-1000원/L, 경유 9050kcal-1433원/L, 면세경유 9050kcal-821/L, 우드 1812kcal-400원/kg, 주박 1989kcal-200원/kg으로 훨씬 저렴하며 열량도 높다. 주류업체에서 주박을 폐기물 처리하므로 가격 책정은 어렵다. $CO_2$ 발생량도 적어 온실가스를 절감시킬 수 있는 친환경적인 청정연료이다. 또한 연료로서 운송, 저장 및 보관이 편리하다. 주류업체도 주박 처리로 인해 연간 12억 정도 사용된다. 폐기물을 에너지화 함으로써 타 신재생에너지에 비해 초기 투자 비용이나 연료비가 저렴하다. 그리고 태우고 남은 회분은 토양개량제로 다시 재활용 되기 때문에 무해백익하다. 현재 폐목재를 사용한 우드펠릿은 원료를 수입해야 한다는 점과 삼림자원의 부족시 문제가 발생할 수 있다. 그리고 폐목재를 분쇄한 후 가공 및 성형을 해야 하기 때문에 주박이 효율성이 좋다. 현재 세계에서 가장 많이 사용되고 있는 석유나 화석연료의 매장량이 고갈 되어가고 있다. 하지만 주박은 술이 사라지지 않는 한 계속적으로 발생하기 때문에 무궁무진하게 사용이 가능하다. 또한 주류 제조시 발생하는 주박은 바로 성형 및 가공이 용이하다. 현재 주박으로 만든 펠릿은 전 세계적으로 전무하다. 막걸리 및 전통술의 특화사업으로 주박량은 더욱 증가하고 있다. 더욱이 2012년부터 해양 투기 금지로 주박 폐기물 처리가 힘들어진다. 주박 폐기물을 펠릿화해서 에너지원으로 사용하면 해결이 된다. 주박의 에너화를 통해 재생산의 열원으로 사용되고 펠릿을 연료원과 더불어 기계적인 시스템을 개발한다면 저탄소 녹색성장인 국가 정책과 부합된 미래형 에너지가 될 것이다.

This paper identified the values and awareness of Koreans in 20s regarding Hanbok, the traditional clothing of Korea, and proposed an approach to promote the traditional clothing culture. The subject of the survey were male and female Koreans in their 20s who wear modern street clothes in places people frequently visit including in the metropolitan area and Chungcheong-do as well as those who wear Hanbok in Seoul and Jeonju, Jeollabuk-do. In accordance with the analysis of the survey, Koreans in their 20s rented Hanok rather than buying it. The respondents wore Hanbok for events, festivals or national holidays or while travelling. Elements to improve in Hanbok rental services were designs, materials, washing and stains. The decision factors for renting Hanbok were 'personal tendency' and 'advice from an expert.' While Koreans in their 20s had a positive awareness of Hanbok, they thought it was difficult to buy, rent and put on Hanbok and that it was not comfortable to wear. There was not sufficient opportunity and means to wear Hanbok due to insufficient accessories or shoes to match. On the basis of the analysis of the survey results, the following approach was proposed for the development of the traditional clothing culture. First of all, develop traditional clothing designers who can satisfy the personalities of Koreans in their 20s. It is necessary to develop experience-focused and participatory programs that provide systematic education regarding traditional clothing to pass down this tradition. In addition, it is necessary to create a social and cultural atmosphere that enables the Koreans in their 20s to easily wear Hanbok by popularizing Hanbok.

With the growing popularity of smart devices, various location based services have been providing to users. Recently, some location based social applications that combine social services and location based services have been emerged. The demands of a k-nearest neighbors(k-NN) query which finds k closest locations from a user location are increased in the location based social network services. In this paper, we propose an approximate k-NN query processing method for fast response time in a large number of users environments. The proposed method performs efficient stream processing using big data distributed processing technologies. In this paper, we also propose a modified grid index method for indexing a large amount of location data. The proposed query processing method first retrieves the related cells by considering a user movement. By doing so, it can make an approximate k results set. In order to show the superiority of the proposed method, we conduct various performance evaluations with the existing method.

Korean historical constellations and their names are similar to Chinese ones. Although Korean historical astronomy is influenced by China, they have distinct differences in each shape and names of the constellations. We, therefore, compare Bocheonga (步天歌) of the early Joseon dynasty (朝鮮, $1392{\sim}1910$) preserved in Gyujanggark (奎章閣) with that of the Sui dynasty ((隋代, $581{\sim}618$ of China written by Wang Ximing(王希明) in terms of star charts and descriptions of the contents. We find out that the two books are partly different all over the books. First, there are definite differences in preface, three area of constellations (三垣) in the heaven, and the description of the Milky Way. Second, some of constellations show different in shape, the number of stars. Especially connecting pattern in some constellations shows different in each other. Third, Joseon Bocheonga describes their colors for some stars. These mean that Joseon has a unique tradition of star maps unlike Chinese one. We also summarize the differences and distinctive characteristics of Joseon star charts compared with Chinese ones.

S. komarovii is halophyte that grows in soil or waters of high salinity, such as in saline semi-deserts, sloughs and seashores. Traditionally, S. komarovii has been used for food and medicinal purposes in Korea. S. komarovii was extracted in 70% ethanol to measure anti-oxidative activity using DPPH and ABTS assay. The IC₅₀ values of the S. komarovii extract against DPPH radicals and ABTS radicals were 186.10 mg/mL and 121.89 mg/mL. In addition, total polyphenol and reducing power were measured. The S. komarovii extract exhibited superior polyphenolic (22.5%) and antioxidant (28.4%) contents. Regarding cell bioactivity, MTT assay was conducted to reveal cytotoxicity of S. komarovii extract and showed the non-cytotoxicity of S. komarovii extract. Anti-inflammatory and skin whitening effects were measured at 100 ㎍/mL. Therefore, this study suggests that the S. komarovii extract can be used as a functional cosmetic product material.

Hanbok industry is not based on a consumer-oriented market system, which is related to poor competitiveness in various areas, such as product planning, marketing, and flow of raw materials. The purpose of this paper is to design and conduct an empirical study on important aspects of consumers. experiences and perspectives about Hanbok, and thereby aims to provide much-needed guidance about ways to promote the Hanbok market. Out of 1065 questionnaires distributed, a total of 1039 was returned with responses and used for analyses. The respondent sample included consumers of various background characteristics in their residential areas, age, gender, education levels, and income levels. Cronbach's alpha and a factor analysis were employed for the reliability and the construct validation of the survey instrument. One-way ANOVA associated with post-hoc comparison tests was used to investigate differences across different demographic subgroups of consumers. The results show that consumers generally view Hanbok as one of the formal dresses, worn one or two times per year for traditional events or ceremonies. Consumers tend to show negative opinions about the pricing, and the inconvenience in cleaning and wearing Hanbok. However, consumers think very highly of the aesthetic values, the gracious styles, and the iconic identity of nationalism of Hanbok. This study suggests that Hanbok for modern consumers should be considered as clothing for a ritual, rather than clothing to reconstruct to be fitted to modern daily lives. Hanbok should be promoted as part of up-scaled and differentiated traditional cultures, as clothing that represents and enhances the traditional elegance and beauty unique to the Korean people.

This paper proposes a motion estimation-based super resolution algorithm to restore input low-resolution images of large movement into a super-resolution image. It is difficult to find the sub-pixel motion estimation in images of large movement compared to typical experimental images. Also, it has disadvantage which have high computational complexity to find reference images and candidate images using general motion estimation method. In order to solve these problems for the traditional two-dimensional motion estimation using the proposed registration threshold that satisfy the conditions based on the reference image is determined. Candidate image with minimum weight among the best candidates for super resolution images, the restoration process to proceed with to find a new image registration algorithm is proposed. According to experimental results, the average PSNR of the proposed algorithm is 31.89dB and this is better than PSNR of traditional super-resolution algorithm and it also shows improvement of computational complexity.
