The purpose of this study is to analyze the formative characteristics of Hanbok among youngsters based on SNS proof shots, identify new characteristics of Hanbok as part of play and travel rather than as formal Hanbok, and provide information for the Hanbok market. As research methodology, our search was carried out by using '#Hanbok Travel' as the search word in Instagram, where the Hanbok proof shot phenomenon is actively under way. A total of 535 posts from March 21, 2016 to April 1, 2016 were selected as objects of this study, excluding posts containing Hanbok with indiscernible shape, Korean traditional costume manufacturers' promotional posts, and repetitive posts by one person. First, the 535 posts were analyzed by season, region, number of people, and gender, and after men's data were excluded, 644 Hanboks were left for analysis. Their formative characteristics were analyzed by using SPSS 21.0. The results showed that the formative characteristics of Hanbok shown in SNS proof shots included diversification of length in jeogori(Korean traditional jacket), skirt, and sleeve, use of pragmatic material and achromatic color, and reduced use of decorative technique. Hanboks shown in the Hanbok proof shots should be considered as significant data because each shots show clothes selected and worn directly by user's side, unlike the existing studies centering on Hanbok designers' works.

Today, visitors of art galleries like to share their life in their communities than interacting with artwork. Meantime, image sharing of an exhibition on social media has become more important than actual watching of the artwork. Accordingly, most of the galleries have started paying more attention in organizing an exhibition environment for proof-shots to attract more visitors. We initially conducted research about the internet environment from the late 1990s to the recent years and analyzed the changing watching patterns of the exhibition since the advent of social media. Secondly, for empirical case analysis, we selected 'Plastic Fantastic' held in D-Museum as the target of analysis. The analysis targeted 500 recent postings that were discovered on Instagram on March 4, 2018, as 'Plastic-Fantastic'(in Korean). The methods of analysis included classification types of image, hashtag, and text on Instagram and were arranged in an order of relation to the exhibits. Based on the image analysis, 44.2% of the images involved exhibition displays; the others included a person or other goods. Based on the results of the text and hashtag analysis, only 3.6% of posting included information about the exhibition and 56.4% had non-related inflow hashtags only with image. The behavior of these shares is likely to gradually lose the inherent meaning of the exhibition and to the value rather than imparting the artistic thrill that viewers derive from art. Exhibition should try to seek deep interaction between the display, audience, and social media users, rather than encouraging the visitors to take proof-shots.

A RAM-based neural network is a weightless neural network based on binary neural network(BNN) which is efficient neural network with a one-shot learning. RAM-based neural network has multiful information bits and store counts of training in BNN. Supervised learning based on the RAM-based neural network has the excellent performance in pattern recognition but in pattern categorization with unsupervised learning as unsuitable. In this paper, we propose a unsupervised learning algorithm in the RAM-based neural network to perform pattern categorization. By the proposed unsupervised learning algorithm, RAM-based neural network create categories depending on the input pattern by itself. Therefore, RAM-based neural network for supervised learning and unsupervised learning should proof of all possible complex models. The training data for experiments provided by the MNIST offline handwritten digits which is consist of 0 to 9 multi-pattern.

Recently, 『Gyeongja(庚子)/Daetongryeok(大統曆)』(1600), a memorandum record of Yu Seong-ryong during the reign of King Seonjo(宣祖) of the Joseon Dynasty, was returned to Korea from Japan, and about 4,000 letters in cursive characters have been interpreted by Ro Seung-suk. The contents for 203 days written in the margin of 『Gyeongja(庚子)/Daetongryeok(大統曆)』 are mostly new, and are meaningful in understanding Yu's life and social association circumstances. There are daily routines of each day, contemporary figures, diseases and oriental medicine prescriptions. In particular, the combat record of Admiral Yi Sun-shin in 83 letters on the cover is very important to understand the situation in those days. It seems that the reason for writing the combat situations a year and a few months after Admiral Yi died in war was to honor his distinguished military service for a long time by King Seonjo's order according to the public opinion of the royal court. The record can be classified into two categories. First, Admiral Yi sighed when he heard about Yu's dismissal from the office in Gogeumdo, and was always alert with clear water on the boat after the Battle of Waekyo Castle. Second, he was killed by bullets shot by the enemy while directly encouraging battle, not listening to his men who tried to dissuade him from leading the naval battle at Noryang. This only contained contents of devoting his life desperately, which is an important proof of the theory of his death in war. It also contains nine methods for making liquor and another method that wasn't known to the public, and seems to include popular alcohol brewing methods or newly devised ones. In addition, there is a detail that Heo Jun, the author of 『Donguibogam』, introduced medicine to Yu, along with being unable to attend ancestral rites and relieving the poor written in red. There are also stories about Kang Hang(姜沆) returning to Korea after being captured by Japan and Lee Deok-hong(李德弘)'s son, who introduced Gugapseondo(龜甲船圖, the first picture of the Turtle Ship in Korea) to King Seonjo. In the light of the above, 『Gyeongja(庚子)/Daetongryeok(大統曆)』is an important historical record to empirically research not only figures related to Yu but also the circumstances of those days since it contains new facts that are not in the existing literature. In particular, the big accomplishment of this study is to correct the mistakenly known theory of Admiral Yi's suicide and to find out the new fact that Heo Jun provided medical information. In this respect, this book is expected to serve as a testament to the future study of the history and characters related to Yu in the mid-Joseon period.
