Since the introduction of carbonated drinks in the 1950s, 'cola' and 'cider'along with orange juice, the dominator of the juice market, have been two main streams of the Korean beverage market. This market pattern has caused the following effects; a. Economical loss due to the import of foreign brands - royalty payments to x company. b. Loss of opportunity to develop a domestic beverage market. c. Inflow of an unfiltered foreign culture. This study shows a change in the Korean beverage market. In the 1980s. consumers' tastes started to change as a trend of developing beverages using traditional Korean ingredients started to begin. On the basis of this change, I would like to discuss the desirable path in developing beverages using traditional ingredients. 'Traditional ingredients'refers to the ingredients that the Korean people have enjoyed within the course of their life, whether it be via food or beverage. These ingredients have been chosen by our people as first rate for centuries. How to modernize and develop these work-in-progress products is the desirable direction for the development of drinks using traditional Korean ingredients. This study also shows various examples of how Korean traditional ingredients and the Western scientific civilization can fuse together to develop a modern and value-added product. One project in particular, created a method of producing a beverage using rice a simple traditional ingredient, marking it a hit product. Through this example, I present the desirable direction of how to develop a modernized drink using traditional ingredients that can change both the consumers' current value on the Korean beverage market as well as create a new pattern of consumer tastes.

Despite well established health benefits, today's children do not eat enough vegetables. The purpose of this study was to determine the association between the number of unfamiliar foods in the vegetable food group and the preference for these foods and dietary factors. Subjects were 1,072 children in 5th and 6th grades from elementary schools located in 4 cities in Gyeonggi-do, Korea. A two-page questionnaire consisted of questions asking about the subjects' preference and familiarity for 64 foods in the vegetable group, preferences for three fast foods, four types of vegetable dishes, and six tastes. Also included in the questionnaire were questions assessing subjects' adherence to national dietary guidelines. The subjects were divided into quintiles according to the number of unfamiliar vegetables; the 1st quintile (N=226) was children who had less than 14 unfamiliar vegetables and the 5th quintile (N=229) was more than 29. Compared to the children in the other quintiles, the children in the 5th quintile had a significantly lower adherence to national dietary guidelines regarding consumptions of vegetable and protein sources, regular exercise, awareness of desirable height and weight, and reading food labels, as well as total (P<0.05). The preferences for bland tastes (P<0.05), salads (saengchae, P<0.01), stir-fried vegetables (P<0.01), and several vegetable items (P<0.05) were significantly lower in the 5th quintile compared to the other quintiles. This study proposes the potential benefits of teaching children names of a variety of vegetables to improve their dietary factors such as food preferences and dietary habits.

The purpose of this study is to investigate the current status and motives of buying second-hand clothing among university students and to suggest a plan to activate second-hand clothing transactions. In order to discover the effect of the buying motives on the purchasing of second-hand clothing, 112 university students who have purchased second-hand clothing over the past six months were surveyed and their responses were used for analysis. As a result of the analysis, it was found that design differentiation, habitual use, and economical factors had a meaningful effect on the purchase of second-hand clothes. Second-hand clothes have a positive environmental perception, but that perception did not impact the purchasing of second-hand clothes. It is necessary to raise the awareness and social movement around second-hand clothing and teach consumers the environmental benefits and sustainability of second-hand clothing. An activation plan for the second-hand clothing market is: 1. Proposes various market subdivisions that meet the characteristics and tastes of consumers that lead to the purchase of used clothing. In this study, two economic factors were found among the buying motives. The first is purchasing second-hand clothing at a very low price, and the second is finding luxurious expensive items or unique values at a lower price. Therefore, it is necessary to find various markets segments that suit consumer tastes by checking consumer characteristics and detailed factors. 2. Nurture second-hand clothing processing brands for the diversification of the second-hand clothing market. 3. There is an urgent need for quality classification, quality assurance, and the standardization of second-hand clothing. This study is meaningful in that it explored the possibility of having a positive effect on activating the second-hand clothing market.

The purpose of this study is to compare and analyze the perception of retro fashion and new-tro fashion using big data. TEXTOM allowed the collection of big data on the words 'retro fashion' and 'new-tro fashion', which was refined afterwards. As for the data collection period, Jan. 1, 2019 to Nov. 30, 2022 was set. A top 50 list of words were extracted from this data based on appearance frequency. The extracted words were processed through Network centrality analysis and CONCOR analysis using Ucinet 6. The results are as follows. 1) In retro fashion, the appearance frequency of 'style' was the highest, followed by 'sensibility', 'color', 'trend', 'fashion', and 'brand'. These words came up with high TF-IDF values. Network centrality analysis discovered that 'color', 'style', 'trend', 'sensibility', and 'design' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; trends, styles, looks, and photos. 2) In new-tro fashion, the appearance frequency of 'retro' was the highest, followed by 'trend', 'generation', 'style', 'brand', and 'fashion'. These words also came up with high TF-IDF values. Network centrality analysis found that 'retro', 'trend', 'generation', and 'brand' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; style, brand, clothing, and trend. 3) New-tro fashion is included in retro fashion in that it reproduces the styles of the past. However, it is taken completely differently from generation to generation. Unlike the older generations, millennials actively accept newly created clothes and brands based on the past styles. They perceive it as a fashion that reveals their own unique tastes and tastes.

There are four kinds of formulas for purging the liver to cure its sthenic syndrome based on the types of preparation formulas : Sagan-tang, Saganhwan, Saseem-san and Saganeum. Another formula called Sacheonghwan, Sacheong-tang and Sacheong-san is to purge the green colour of liver. There are 38 kinds of Sagan-tang, 2 kinds of Saganhwan, 29 kinds of Sagan-san, 5 kinds of Saganeum, 4 kinds of Sacheonghwan, 3 kinds of Sacheong-tang and 1 kind of Sacheong-san. Combination of herbal medicines, carried out in formulas for purging the liver, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Sagan-tang for curing the sthenic syndrome of liver through analyzing the component medicines and combination principles of Hyeongok's Sagan-tang, and furthermore, maximizing the clinical use of Sagan-tang. This study analyzed the component medicines and combination principles of Hyeongok's Sagan-tang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$Yellow Emperor's Canon of Internal Medicine${\lrcorner}$, the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Sagan-tang is an odd prescription, composed of 7 kinds of ingredients : No.1 Radix Paeoniae (2don;7.5 g), No.2 Fructus Chaenomelis (1don;3.75 g), No.3 Radix Rehmanniae (1don), No.4 Folium Phyllostachydis Henonis (1don), No.5 Radix Bupleuri (1don), No.6 Radix Scutellariae (1don), and No.7 Radix Glycyrrhizae (1don). There are three methods for curing the sthenic syndrome of liver according to the five elements doctrine : purging the liver, purging the heart and invigorating the lung. In the case of taste purgation, two herbal medicines with sour taste, Radix Paeoniae and Fructus Chaenomelis, are combined into the principal and assistant herbal medicine, respectively. For property purgation, two herbal medicines with the cool property, Radix Bupleuri and Radix Scutellariae, are combined into adjuvant herbal medicines. Both sweet and cold herbal medicines, Radix Rehmanniae and Folium Phyllostachydis Henonis, are combined into adjuvant herbal medicines. Sour herbal medicines, Radix Paeoniae and Fructus Chaenomelis, were combined to invigorate the lung. Cool herbal medicines, Radix Bupleuri and Radix Scutellariae, were combined to invigorate the lung and to purge the liver. In addition, Radix Glycyrrhizae are combined as dispatcher herbal medicine, harmonizing all the herbal medicines composing the formula. First, to cure the sthenic syndrome of the liver, the methods of purging the liver and the heart, and invigorating the lung should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herbal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Sagan-tang is combined according to the above theories.

상품 검색시간의 단축과 쇼핑에 투입되는 노력의 감소 등, 온라인 쇼핑이 주는 장점에 대한 긍정적인 인식이 확산되면서 전자상거래(e-commerce)의 중요성이 부각되는 추세이다. 전자상거래 기업들은 고객확보를 위해 다양한 인터넷 고객관계 관리(eCRM) 활동을 전개하고 있는데, 개인화된 추천 서비스의 제공은 그 중 하나이다. 정확한 추천 시스템의 구축은 전자상거래 기업의 성과를 좌우하는 중요한 요소이기 때문에, 추천 서비스의 정확도를 높이기 위한 다양한 알고리즘들이 연구되어 왔다. 특히 협업필터링(collaborative filtering: CF)은 가장 성공적인 추천기법으로 알려져 있다. 그러나 고객이 상품을 구매한 과거의 전자상거래 기록을 바탕으로 미래의 추천을 하기 때문에 많은 단점들이 존재한다. 신규 고객의 경우 유사한 구매 성향을 가진 고객들을 찾기 어렵고 (Cold-Start problem), 상품 수에 비해 구매기록이 부족할 경우 상관관계를 도출할 데이터가 희박하게 되어(Sparsity) 추천성능이 떨어지게 된다. 취향이 독특한 사용자를 뜻하는 'Gray Sheep'에 의한 추천성능의 저하도 그 중 하나이다. 이러한 문제인식을 토대로, 본 연구에서는 소셜 네트워크 분석기법 (Social Network Analysis: SNA)과 협업필터링을 결합하여 데이터셋의 특이 취향 사용자 (Gray Sheep) 문제를 해소하는 방법을 제시한다. 취향이 독특한 고객들의 구매데이터를 소셜 네트워크 분석지표를 활용하여 전체 데이터에서 분리해낸다. 그리고 분리한 데이터와 나머지 데이터인 두 가지 데이터셋에 대하여 각기 다른 유사도 기법과 트레이닝 셋을 적용한다. 이러한 방법을 사용한 추천성능의 향상을 검증하기 위하여 미국 미네소타 대학 GroupLens 연구팀에 의해 수집된 무비렌즈 데이터(http://movielens.org)를 활용하였다. 검증결과, 일반적인 협업필터링 추천시스템에 비하여 이 기법을 활용한 협업필터링의 추천성능이 향상됨을 확인하였다.
